Abstract:

In order to succeed, it is imperative that all e-commerce systems include an effective and reliable trust and reputation modeling system. This is particularly true of decentralized e-commerce systems in which autonomous software engage in commercial transactions. Many researchers have sought to overcome the complexities of modeling a subjective, human concept like trust, resulting in several trust and reputation models. While these models each present a unique offering and solution to the problem, several issues persist. Most of the models require direct experience in the e-commerce system in order to make effective trust decisions. This leaves new agents and agents who only casually use the e-commerce system vulnerable. Additionally, the reputation ratings of agents who are relatively new to the system are often indistinguishable from scores for poorly performing agents. Finally, more tactics to defend against agents who exploit the characteristics of the open, distributed system for their own malicious needs are required. To address these issues, a new metric is devised and presented: seniority. Based on agent age and activity level within the e-commerce system, seniority provides a means of judging the credibility of other agents with little or no prior experience in the system. As the results of experimental analysis reveals, employing a reputation model that uses seniority provides considerable value to agents who are new agents, casual buyer agents and all other purchasing agents in the e-commerce system. This new metric therefore offers a significant contribution toward the development of enhanced and new trust and reputation models for deployment in real-world distributed e-commerce environments.

Abstract:

Joseph E. Levine has been largely neglected by Film Studies, yet he was a uniquely important figure in the US film industry during his lifetime. As an independent producer, distributor and promoter, Levine's influence on the post-War cinematic landscape of the US was wide-ranging and profound. His versatility and multifariousness were unsurpassed during his lifetime and analysis of his abilities, strategies and influence complicates many areas of current film scholarship. Levine was a very prominent figure in the popular press where he was perceived as a master showman. His prominence and hyperbolic style undermines the traditional understanding of the cultural intermediary, a role usually associated with discretion. Levine's conspicuousness led to him becoming an easily identifiable public figure yet, due to his varied output, he resists the notions of branding that are often associated with prominent figures in the film industry. Studies of reputation building strategies are often closely aligned to critical approval, yet Levine never courted critical favour. Although Levine's output catered for many niche tastes, his public image was unabashedly populist. He would, however, utilise the critical adulation bestowed on others to bolster his own reputation as a supporter of talent, providing an ideal case study for the complex political interactions of reputational assessment. As a pioneer of industrial strategy and practice, Levine was hugely influential. He pioneered saturation publicity and opening tactics and was an early advocator of the use of television in movie marketing, and therein he represents a vital missing link in the evolution of blockbuster marketing techniques. He was similarly influential regarding the marketing and distribution of art cinema and, in the 1960s and 1970s, he helped to redefine the role of the independent producer. All these factors combine to make Levine an ideal vantage point for surveying cultural and filmic mores of the post-War US. His career was one of extraordinary contradictions and complexities. An analysis of his career provides a deepening of understanding of film historiography of this era and calls into question many commonly held scholarly assumptions regarding taste cultures, cultural boundaries and the supposed demarcation between independent and major studio film production.

Abstract:

L'E-réputation est un syntagme dont la construction laisse entendre que la révolution technologique dans les télécommunications assure une emprise sur la notion de réputation. Ce phénomène semble avoir une véritable existence dans la littérature, dans la doctrine et dans les sources normatives. Il s'agit d'une vérité sociale qui passe dans le langage et dans les pratiques juridiques. L'E-réputation nécessite d'étudier des notions juridiques distinctes de la réputation qui sont englobées par l'E-réputation, une fois confrontées à la dimension numérique. Cette analyse a pour ambition de : - dresser un schéma intelligible original des règles de droit mobilisables dans la résolution d'une problématique liée à l'E-réputation, - proposer une méthodologie de mise en œuvre de ces règles de droit qui combine les usages professionnels actuels et des propositions tirées des résultats de cette analyse
E-reputation is a syntagm whose construction suggests that the technological revolution in telecommunications ensures a grip on the notion of reputation. This phenomenon seems to have a real existence in literature, in doctrine and in normative sources. It is a social truth that pass in legal language and practice. E-reputation requires studying distinct legal notions of reputation that are encompassed by E-reputation, when faced with the digital dimension. This analysis aims to : - draw up an original intelligible diagram of the rules of law that can be mobilized in the resolution of a problem related to E-reputation, - propose a methodology for implementing these rules of law that combines current professional uses and proposals drawn from the results of this analysis

Abstract:

Reputation systems have the potential of improving the quality of on-line markets by identifying fraudulent users and subsequently dealing with these users can be prevented. The behaviour of participants involved in e-commerce can be recorded and then this information made available to potential transaction partners to make decisions to choose a suitable counterpart. Unfortunately current reputation systems suffer from various vulnerabilities. Solutions for many of these problems will be discussed. One of the major threats is that of unfair feedback. A large number of negative or positive feedbacks could be submitted to a particular user with the aim to either downgrade or upgrade the user's reputation. As a result the produced reputation does not reflect the user's true trustworthiness. To overcome this threat a variation of Bayesian Reputation system is proposed. The proposed scheme is based on the subjective logic framework proposed Josang et al. [65]. The impact of unfair feedback is countered through some systematic approaches proposed in the scheme. Lack of anonymity for participants leads to reluctance to provide negative feedback. A novel solution for anonymity of feedback providers is proposed to allow participants to provide negative feedback when appropriate without fear of retaliation. The solution is based on several primitive cryptographic mechanisms; e-cash, designated verifier proof and knowledge proof. In some settings it is desirable for the reputation owner to control the distribution of its own reputation and to disclose this at its discretion to the intended parties. To realize this, a solution based on a certificate mechanism is proposed. This solution allows the reputation owner to keep the certificate and to distribute its reputation while not being able to alter that information without detection. The proposed solutions cater for two modes of reputation systems: centralised and decentralised. The provision of an off-line reputation system is discussed by proposing a new solution using certificates. This is achieved through the delegation concept and a variant of digital signature schemes known as proxy signatures. The thesis presents a security architecture of reputation systems which consists of different elements to safeguard reputation systems from malicious activities. Elements incorporated into this architecture include privacy, verifiability and availability. The architecture also introduces Bayesian approach to counter security threat posed by reputation systems. This means the proposed security architecture in the thesis is a combination of two prominent approaches, namely, Bayesian and cryptographic, to provide security for reputation systems. The proposed security architecture can be used as a basic framework for further development in identifying and incorporating required elements so that a total security solution for reputation systems can be achieved.

PONTIFÍCIA UNIVERSIDADE CATÓLICA DO RIO DE JANEIRO
A vez das plataformas de marketplace online finalmente chegou no Brasil, um modelo de negócio que conecta compradores com vendedores por meio de um intermediário. A aplicação desse tipo de comércio em larga escala trouxe consigo diversas modificações no relacionamento entre empresas e consumidores dentro de um ambiente online já bastante carregado de incertezas acerca do objeto de compra. No entanto, grandes empresas que exercem o papel de intermediadoras nessas plataformas, passam a priorizar o volume de acessos de usuários em seus domínios acima das demais atividades relacionadas ao processo de compra em si. O crescente número de reclamações e processos visando reparação de danos de consumidores indica uma piora no setor em geral. Nesse sentido, essa pesquisa busca investigar a importância relativa das percepções do comprador sobre as reputações dos vendedores terceiros, e, seus efeitos na relação de risco percebido e confiança das empresas envolvidas no modelo de marketplace e os consequentes impactos na intenção de compra dos consumidores online. Uma survey online foi conduzida com indivíduos brasileiros que compraram em lojas virtuais ao longo dos últimos 12 meses. Os dados obtidos confirmam as hipóteses colocadas, sugerindo que avaliações de reputações de vendedores exercem influência na intenção de compra por meio de percepções de confiança e risco percebido no processo de compra. Algumas sugestões são propostas para que empresas do setor de e-commerce otimizem seus esforços dentro e fora de ambientes de marketplaces online.
Online marketplace platforms finally arrived in Brazil, a business model that connects buyers with sellers through an intermediary party. This particularly application of commerce in large scale has brought with it several modifications in the relationship between companies and consumers, taking in account an online environment already quite loaded with uncertainties on buy process. However, large companies that act as intermediaries in these platforms, prioritize the volume of user accesses in their domains above the other activities related to the purchase process itself. The growing number of complaints and lawsuits seeking compensation for consumer losses indicates a decline in the industry as a whole. Considering that, this research seeks to investigate the relative importance of buyer perceptions on the reputations of third-party vendors and their effects on the perceived risk and trust relationship of the companies involved in the marketplace model and the consequent impacts on consumers online purchase intention. An online survey was conducted with Brazilian individuals who shopped at virtual stores over the last 12 months. The research s data confirmed all the hypotheses formulated, suggesting that evaluations of reputations of seller s influence in the intention to buy through perceptions of confidence and perceived risk. Some suggestions are proposed for companies in the e-commerce industry to optimize their efforts inside and outside marketplaces online.

Abstract:

As plataformas de e-marketplace (EM) atuam como um ponto de encontro virtual, onde vendedores e compradores encontram-se e eventualmente fecham negócios. Em um EM, diversos vendedores competem entre si anunciando ao mesmo tempo produtos exatamente iguais por preços possivelmente diferentes. No entanto, não necessariamente o anúncio mais barato é o que realiza a venda. Dado que nos anúncios publicados nestas plataformas há um grande conjunto de elementos sob responsabilidade do operador do EM, iguais entre todos os anúncios, este trabalho busca colaborar com a compreensão dos fatores controláveis pelo vendedor que influenciam na geração de preço-prêmio em e-marketplaces. A partir da revisão de pesquisas anteriores sobre o tema, foi elaborado um modelo que considera que a geração do preço-prêmio é influenciada pelas características do vendedor (reputação, porte e localização), do anúncio (utilização de recursos multimídia, divulgação, opções de pagamento e entrega, serviço e histórico do anúncio) e do produto (condição e tipo). Para validar este modelo, foi desenvolvido um programa que ao longo de 56 dias coletou dados reais de vendas de três produtos diferentes (celulares iPhone, videogames Playstation 4 e tênis femininos da marca Osklen) no maior e-marketplace deste tipo no Brasil. Estes dados analisados e utilizados para a verificação de nove hipóteses. A reputação que o vendedor construiu ao longo das vendas anteriores mostrou-se como um importante fator de influencia. Vendedores com boa reputação conseguem vender com preços maiores, assim como vendedores com pior reputação são penalizados nos valores de suas vendas. O porte dos vendedores influencia positivamente até certo ponto. Existem vendedores de grande porte que, possivelmente se beneficiando dos ganhos de escala, praticam preços menores. A localização do vendedor é relevante no preço da venda e esta relevância varia de acordo com o produto. Também há diferença na influência de acordo com o produto para a utilização de recursos multimídia e para o envio da nota fiscal junto ao produto. Pagar por um pouco mais de exposição que os padrão oferecido pela plataforma gratuitamente permitiu a realização de vendas com preços maiores, mas o efeito oposto foi observado quando pagou-se pela máxima exposição possível. Também venderam por valores mais altos os anúncios mais antigos e os que ofereceram frete gratuito.
E-Marketplace (EM) platforms are virtual meeting points where sellers and buyers can meet and eventually close a deal. In an EM, various sellers compete against each other offering similar products with different prices. The cheapest offer is not necessarily the one that make the sale. As listings published in an EM have a great number of elements controlled by the platform operator, hence equal to all listings. This work aims to understand the factors controllable by the seller that can influence premium price generation in EMs. Based on the existing literature a model is proposed, in which premium price is influenced by seller characteristics (reputation, size and location), listing characteristics (multimedia resources, exposure, payment and shipping methods, service and ad history) and product (item condition and type). To validate this model a software was developed to collect real data from the largest retail EM in Brazil. During 56 days sales of three products (iPhone smartphones, Playstation 4 videogame consoles and Osklen female tennis shoes) were watched and stored in a database. This data was analyzed and used for verification of nine hypotheses. Reputation acquired by a seller with his previous sales was found as an important element influencing the sale price. Sellers with good reputation were able to sell its items by a higher price and sellers with bad reputation had to sell it cheaper. Seller size exerted positive influence to some extent. Big retailers selling in the EM may be able to sell for a smaller price and make profit thanks to the economies of scale. Seller localization is also relevant. The intensity of this relevance varies by product. It was also noticed difference according to the product for the use of multimedia resources and to if the seller says it will provide a tax invoice attached for the sale. Paying to the EM operator for some additional exposure also made it possible for the seller to achieve prices, but the effect was the opposite when the seller paid for the maximum exposure possible. Old listings and listings that offered free shipping also reached higher prices.

Atualmente, a atribuição de novas tecnologias aliadas à computação distribuída tem crescido exponencialmente devido a necessidade cada vez mais imposta de otimização dos recursos computacionais. As redes P2P (Peer-to-Peer) são um exemplo de arquitetura de sistemas distribuídos onde os nós atuam tanto na função de clientes como na de servidores. A relação desses nós participantes apresenta questões relacionadas à confiança devido as comunicações que esses realizam, e uma vez que o comportamento dos nós é dinâmico, indicam-se problemas voltados a segurança. Dessa forma, um sistema de reputação e confiança é um meio de se controlar o funcionamento da rede e demais problemas através de métodos de recompensa e penalização. Analisando o contexto de aplicação, nota-se que utilizar um mecanismo de penalização para limitar largura de banda, como acontece tradicionalmente em sistemas P2P, não é uma alternativa viável para ambientes LAN, devido justamente aos recursos que esse tipo de rede detém como característica própria. Dentre diversas outras possibilidades, a limitação de acesso às informações sobre os arquivos compartilhados evidencia adequadamente uma maneira concisa e aplicável para tratar a penalização em redes locais. Este trabalho tem como objetivo então o desenvolvimento de um sistema de reputação para redes locais, denominado TrustLP2P. O TrustLP2P propõe um modelo que visa adequar os aspectos do ambiente de rede local ao mesmo tempo em que atribui conceitos baseados em outros sistemas de reputação existentes, fazendo uso de valores de reputação e confiança para que os nós possam classificar uns aos outros. Aliado a isso, mensurando através dos valores de reputação os participantes, o sistema também tem por finalidade recompensar ou penalizar os nós de acordo com seu comportamento. Um exemplo de aplicação para o TrustLP2P é o LP2P (Local Peer-to-Peer ), uma plataforma de comunicação para ambientes distribuídos voltada para o compartilhamento de arquivos, desenvolvida pelo projeto da linha de pesquisa de Redes de Computadores e Sistemas Distribuídos do PIPCA, Unisinos. Assim, o sistema proposto proporciona ao LP2P um controle adequado sobre as ações dos nós, através de aspectos consistentes que são descritos no seu modelo.
Currently, assign new technologies designed to distributed computing has grown exponentially due to the need for optimization of computing resources. The P2P (Peer-to-Peer) is an example of architecture of distributed systems where the nodes work both in the role of client as the server. The relationship of these nodes presents issues relating to the trust due the communications between them, and since the behavior of nodes is dynamic, security problems are indicated. Thus, a reputation and trust system is one way to control the operation of the network and other problems through methods of reward and punishment. Analyzing the application context, it is notable that use a penalty mechanism to limit bandwidth, as traditionally happens in P2P systems, it is not a viable alternative for LAN environments, due to the resources that this type of network has its own characteristic. Among several other possibilities, limiting access to information about the shared _les shows a concise and applicable manner to establish the penalty in local networks. This study aims to develop a reputation system for local networks, called TrustLP2P. The TrustLP2P proposes a model that adapts aspects of the local network environment at the sime time that related concepts based on other existing reputation systems, making use of reputation and trust values so that the nodes can classify each other. Allied to this, measuring the values of reputation through the participants, the system also aims to reward or penalize the nodes according to their behavior. An application for TrustLP2P is LP2P (Local Peer-to-Peer), a communication platform for distributed environments focused on the sharing of _les, developed by the research project of Computer Networks and Distributed Systems of PIPCA, Unisinos. Thus, the proposed system provides for LP2P an adequate control over the actions of the nodes, through consistent aspects that are described in their model.

Abstract:

Social media is an ideal environment for online small to medium sized enterprises (e-SMEs) to build and develop brand communities. However, there is currently limited research investigating how initial and continual consumer trust is formed through this type of engagement for new and existing e-SME customers. Conducted from three data sets (an e-SME social media netnography, key informant and consumer interviews) this thesis investigates this issue by developing a framework highlighting how engagement within social media brand communities can influence e-SME brand trust. The findings identify eight core trust themes which positively influence initial and continual consumer trust, expanding the existing online consumer trust literature. The increasing role of engagement is also investigated with strategic avenues identified, as well as the influential effect engagement can have on loyalty and trust. This thesis also investigates how e-SMEs can identify business value from the use of social media and increase corporate reputation through social media brand communities. Business value through social media brand community engagement is found to lie primarily in the lasting relationships developed and trust created for consumers. This thesis provides an important contribution to knowledge by increasing the theoretical and managerial understanding of social media brand community engagement for e-SMEs, and how the effects of such engagement can influence consumer trust and reputation.

Abstract:

As the adoption of mobile devices grows around the world, the use of this tool to access the internet and, consequently, interact with a mobile store is also growing. A mobile commerce that is trustworthy tends to have advantages if compared to its competitors and, therefore, better results. This study focuses on understanding and measuring the influence of trust antecedents applied to mobile commerce, in Brazil. The final antecedents found are Data Controls, Website Interactivity, Reputation and Willingness to Customize. The results indicate that Data Controls, followed by Reputation and Website Interactivity are the main influencers of Trust. If Reputation is not considered as part of the model, Website Interactivity becomes an important antecedent. The results provided in this thesis are relevant, since there is a lack of research related to trust in mobile commerce. It has deep practical applications by helping an online business to focus on actions that are essential to build trust through a device with such differentiated capabilities and dynamics of use.

Title: French luxury companies: Challenge to do E-Commerce withoutaffecting their brand image Authors: Clément LEMAIRE and Paul LASSALLE Supervisor: Jean-Charles Languilaire Level: Bachelor Thesis in Business Administration, Marketing Key words: Marketing, E-commerce, E-merchandising, E-CRM, Louis Vuitton, Luxury market, French market, Website, Brand and Reputation Purpose: How French luxury companies, in a context of changing demand, use the e-commerce without affecting the image of their brand? Method: In the method we explain that we decide to use a descriptive method of research. We collect secondary data from our University Library and primary data from our observation of Louis Vuitton website. We also explain why we choose this company and what the limits of our study are. Theoretical framework: In a first part, we have written all the definitions and information about definitions that we have used in the empirical part. It means E-Commerce, E-Merchandising, Marketing mix and ECRM. Then, we have given some information about website elements as the first page, the graphic website, buying process, electronic payment and website security. Finally, we have defined all the information about the brand and its different powers on the market: We start by a “brand awareness” explication, then we have defined “how is build a brand” to finish by the topic “band and reputation”. Conclusions: We present the answer of our purpose. French Luxury companies use marketing tools in order to protect the image of their brand when they do e-commerce. We also bring some suggestions to Louis Vuitton and give some critics concerning our study. Finally we open our reflexion to related studies that could be interesting to do.

Abstract:

Ce travail décrit les logiques et les processus des contributions des salariés sur les médias sociaux, pour analyser les relations et les enjeux entre la présence numérique des salariés et celle de l'entreprise. La thèse fait appel à un cadre conceptuel pluridisciplinaire : théorie du don et les théories du capital social et du capital symbolique pour analyser la logique sous-jacente de la contribution, les notions d’ordre de l’interaction et de genres de contribution pour appréhender le processus de la contribution et enfin, les notions de présence numérique et de gouvernementalité pour aborder les enjeux de la contribution. La posture interprétativiste justifie une méthodologie de recherche qui repose sur trois approches complémentaires : une étude exploratoire, six études de cas et une étude Delphi. Les résultats desdifférentes études menées montrent que la contribution des salariés aux médias sociaux repose principalement sur une logique de légitimation de la "figure du contributeur", que le processus de contribution se concrétise dans un répertoire des "genres de contributions" et que les "traces numériques" définissent les enjeux de la présence numérique des salariés et de l'entreprise
This work describes the logic and the processes of employees’contributions on social media in order to analyze the relationships and issues between their own numerical presence and that of their company. Our thesis is based on a multidisciplinary framework: we mobilized the the gift theory as well as the theories of social and symbolic capital in order to understand contribution logic, the notions of interaction order and contribution genres in order to understand the contribution process and, finally, the concepts of numerical presence and governmentality in order to address the contribution issues.Our research methodology adopts an interpretativist approach, based on three complementary studies: an exploratory study, six case studies and a Delphi study. The results show that employees’ contribution to social media is primarily based on a logic of legitimizing the "figure of the contributor", the contribution process materialized in a repertoire of "contributions genres" and that "digital traces" define the challenges of the numerical presence of employees and that of their company

Abstract:

Avec les mutations de l’internet induites par le développement des outils collaboratifs (blogs, flux RSS, réseaux sociaux, partage d’informations...) l'information change de nature. Sa production devient de plus en plus simple. L'utilisateur, qui depuis les débuts de l’internet grand-public, se contentait d’un rôle de consommateur tout-court d'informations s'est, petit-à-petit, transformé en « consommateur-producteur ». Il est au cœur du nouveau système de production et de diffusion de l’information. Ce changement qui s'opère dans toutes les couches sociales avec comme caractéristiques principales la floraison des blogs, la veille personnalisée, la customisation des outils, le partage, la collaboration dans les réseaux sociaux ..., s’identifie à travers les appellations « web 2.0 », « web social », « web collaboratif ». Plus que des mots, il s’agit de pratiques informationnelles qui mettraient en cause les acquis des entreprises en matière de veille et d'Intelligence Économique. Ainsi, l'intérêt de mesurer les tenants et les aboutissants de ce renouvellement des usages informationnels nous pousse à travers cette thèse à s’interroger sur leur impact réel ou supposé dans la veille et l'Intelligence Économique. Ce travail propose de mesurer le degré de récupération des compétences des utilisateurs du web 2.0 dans les démarches de veille et d’IE en PME et TPE. À l’issue d’une enquête de terrain portant sur un échantillon de 70 entreprises de différentes régions du monde (France, États-Unis, Grande-Bretagne, Maroc, Sénégal…) il a été intéressant de constater que le web 2.0 est assez bien connu dans les entreprises quelle que soit leur taille. Toutefois, la récupération de ses applications dans une démarche de veille et d’Intelligence Économique reste assez dispersée du fait, notamment, de la méconnaissance des potentialités de certains outils, qui a comme conséquence leur non prise en compte dans les politiques informationnelles. Ce résultat nous a convaincu de proposer aux TPE et aux PME une démarche de mise en place d’un dispositif de veille collaborative qui a l’originalité d’intégrer les outils du web 2.0. S’inscrivant dans la logique d’un dispositif de veille de seconde génération (Lietzelman et al.), la démarche proposée constitue une amélioration de celles déjà existantes (AFNOR, Paul Degoul). Elle prend en compte dans chacune des phases (conception, planification et mise en œuvre) la dimension sociale de l’internet et de ses pratiques. Un exposé de techniques d’exploitation de certains de ces outils pour un problème de veille a été produit afin de sensibiliser sur leurs potentialités dans l’éventualité de leur intégration dans un système de veille et d’intelligence économique
With the web as a platform and the development of collaborative tools (blogs, RSS feeds, social networking, information sharing ...) information is changing and its production becomes increasingly simple. The average user, who since the advent of the Internet has merely a short role as consumer of information, is transformed into a "consumer-producer" of information. He is at the heart of the new system of production and dissemination of information. This change whose characteristics cannot be ignored: blogs, personal monitoring, social bookmarking, personalization tools for research, collaboration in social networks etc. and known under the names "Web 2.0", "social web", "collaborative web" would undermine the achievements of companies in terms of information monitoring and Competitive Intelligence (CI); hence the importance of measuring the ins and outs of this renewal informational practices. In addition to questions about the real or supposed changes in information monitoring and Competitive Intelligence in the Age of social web, our research also wanted to measure the degree of recovery skills of web 2.0’s users in SMEs CI‘s systems. With a field survey covering a sample of 70 companies from different regions of the world (France, USA, Great Britain, Morocco, Senegal ...) we noticed that the Web 2.0 is fairly well known by companies regardless of their size, but the recovery of its applications in a process to monitor information is dispersed (using disparate, breach of certain tools potential, lack of information policy incorporating tools 2.0...). This result has convinced us to propose to the SME an approach of establishing a collaborative information monitoring system which has the originality to include the tools of Web 2.0 since the phases of design, planning and implementation. In order to respect the logic of a second generation Information Monitoring System (Lietzelman et al.), the proposed approach is an improvement of existing ones like the AFNOR system or that of Paul Degoul. It is accompanied, for sensitizing SME by a statement of operational techniques of some social media tools for their possible inclusion in a Competitive Intelligence System

Abstract:

CoordenaÃÃo de AperfeiÃoamento de Pessoal de NÃvel Superior
A intensificaÃÃo das relaÃÃes entre os mercados globalizados tem reflexo relevante nas organizaÃÃes, de forma que, para permanecerem no mercado, elas necessitam preservar e aprimorar sua imagem perante seus stakeholders. Nesse sentido, emerge o conceito de reputaÃÃo, frequentemente discutido no contexto das organizaÃÃes, e que pode ser entendido como o conjunto de atributos organizacionais desenvolvidos ao longo do tempo, que influencia na forma pela qual os stakeholders percebem as empresas no mercado. No presente estudo, a reputaÃÃo corporativa Ã analisada na perspectiva da sustentabilidade e de sua influÃncia no desempenho superior e persistente das empresas, sob a fundamentaÃÃo da teoria da sinalizaÃÃo. EvidÃncias empÃricas revelam que as aÃÃes socialmente responsÃveis por parte das empresas lhes conferem reputaÃÃo favorÃvel, na medida em que emitem sinais positivos ao mercado, propiciando maior atratividade aos stakeholders, uma vez que estes percebem maior confianÃa e menor risco (FOMBRUN; SHANLEY, 1990; FOMBRUN; RINDOVA, 1996; FOMBRUN; VAN RIEL, 1997; SCHULTZ; NIELSEN; BOEGE, 2002; GARDBERG; FOMBRUN, 2002; ROBERTS; DOWLING, 2002; CAIXETA et al. 2011). Ao atrair e firmar suas relaÃÃes com os vÃrios stakeholders, garante-se a conquista da vantagem competitiva sustentÃvel, ou do desempenho superior e persistente, das empresas no mercado (BARNEY, 1991; TIERGARTEN; ALVES, 2008; SARAIVA JUNIOR; ALCALDE; COSTA, 2009). A abrangÃncia de estudos anteriores sobre o tema nÃo permitiram anÃlise da longevidade dos benefÃcios conquistados pela boa reputaÃÃo corporativa e nem em contextos mercadolÃgicos diferenciados. Nesse contexto, o presente estudo tem o objetivo de investigar a relaÃÃo entre a reputaÃÃo corporativa e o desempenho superior e persistente das companhias de capital aberto que publicam relatÃrios de sustentabilidade, segundo a listagem do Global Reporting Initiative (GRI). Para tanto, trata-se de uma pesquisa descritiva e explicativa, de natureza quantitativa, utilizando-se os procedimentos bibliogrÃfico e documental, com a aplicaÃÃo das ferramentas estatÃsticas AnÃlise de CorrespondÃncia (Anacor), Teste de MÃdia, AnÃlise fatorial e AnÃlise em painel, no perÃodo de 2008 a 2011. O estudo se justifica na medida em que busca contribuir para ampliaÃÃo da discussÃo sobre a reputaÃÃo corporativa na perspectiva da sustentabilidade. AlÃm disso, apresenta uma anÃlise diferenciada, por tratar do tema relacionando-o com o desempenho superior e persistente, verificando se a reputaÃÃo corporativa se relaciona com a conquista e preservaÃÃo da vantagem competitiva sustentÃvel. A Anacor aponta que as empresas com mais elevados nÃveis de reputaÃÃo figuram no grupo de empresas com maior desempenho. AlÃm disso, o teste de mÃdia realizado demonstra que as empresas com desempenho superior e persistente possuem reputaÃÃo estatisticamente diferente das empresas sem desempenho superior e persistente, sendo que aquelas apresentaram mÃdia de Ãndice de reputaÃÃo corporativa maior do que estas. A anÃlise de dados em painel preliminarmente realizada indicou que nÃo hÃ associaÃÃo entre a reputaÃÃo corporativa e o desempenho superior e persistente, refutando a hipÃtese da pesquisa. PorÃm, ao transformar as variÃveis em fatores e utilizar estes na anÃlise de dados em painel, identificou-se relaÃÃo de dependÃncia do desempenho para com os fatores porte (representado pelo tamanho) e credibilidade (representado pelo endividamento e reputaÃÃo). Logo, conclui-se que, para a amostra considerada, a reputaÃÃo sozinha nÃo Ã capaz de influenciar o desempenho empresarial, mas levando em conta o endividamento, o fator credibilidade (constituÃdo pelos fatores endividamento e reputaÃÃo) pode ser explicativo do desempenho. Assim, conforme a Teoria da SinalizaÃÃo, a reputaÃÃo representa sinais emitidos ao mercado capaz de influenciar o comportamento dos stakeholders, impactando seu desempenho.
The intensification of relations between the global markets presents a relevant reflection on organizations, so as to remain in the market, they need to further preserve and improve their image in front of their stakeholders. In this sense, the concept of reputation emerges, being often discussed in the context of organizations and moreover can be understood as the set of organizational attributes developed over time, which influences the way stakeholders perceive companies within the market. In this study, corporate reputation is examined from the perspective of sustainability and of its influence in the companiesâ superior and persistent performance under the theory of signalingâs foundation. Empirical evidence reveals that socially responsible actions taken by companies provide them a favorable reputation, as they issue positive signals to the market, offering greater attractiveness to stakeholders since they perceive higher reliability and lower risks (Fombrun, Shanley 1990; Fombrun; RINDOVA, 1996; Fombrun, Van Riel 1997, SCHULTZ, Nielsen; BOEGE, 2002; GARDBERG; Fombrun, 2002; ROBERTS & Dowling, 2002; CAIXETA et al. 2011). By attracting and establishing their relationships with various stakeholders, the achievement of either sustainable competitive advantage or the superior persistent performance is assured in the market companies (Barney, 1991; TIERGARTEN; ALVES, 2008; HAIL JUNIOR; ALCALDE; COSTA, 2009). The scope of these previous studies on the topic did not allow analysis of the longevity of the benefits gained by neither good corporate reputation nor in differentiated market contexts. Within this context, this study aims at investigating the relationship between corporate reputation and superior persistent performance of public companies that publish sustainability reports, according to Global Reporting Initiative (GRI)âs listing. It is a descriptive and explanatory research of quantitative nature, using bibliographic and documentary procedures with the application of statistical tools Correspondence Analysis, Average Testing and Panel Analysis. The studyâs justification is to seek to contribute on expanding the discussion on corporate reputation in the perspective of sustainability. Moreover, it presents a differentiated analysis for dealing with the issue relating to the superior persistent performance and checking whether corporate reputation relates to the achievement and maintenance of a competitive advantage for a long period of time. Anacor points out that companies with higher levels of reputation are included in the group of companies with higher performance. Moreover, the conducted average testing shows that companies with superior persistent performance regard a statistically different reputation from their counterparts without superior persistent performance, being that the former presented an average index of corporate reputation greater than the latter. The preliminarily performed panel data analysis indicated no association between corporate reputation and superior persistent performance, disproving the research hypothesis. However, by transforming the variables into factors and using them in the panel data analysis, a performance dependency relationship was identified regarding size (represented by its size) and credibility (represented by its debt and reputation) factors. Therefore, it is concluded that, for the sample considered in this research, reputation alone is not able to influence business performance, but taking debt into account; the credibility factor (grouping the reputation and debt factors) may provide further explanations about performance. Thus, according theory of signaling, the reputation represents signals to the market and it is able to influence the behavior of stakeholders, impacting their performance.

Abstract:

The social responsability is a hot topic and, in recent years has been consolidated with the belief that companies should assume a larger role to the society that not only the maximization of profit and wealth creation. From these assumptions, the study assesses the impact of adopting sustainable business strategies on the performance of Brazilian industrial firms. The study's findings should support the development of a model of excellence for world-class management aligned with international requirements to ensure the entry and maintenance of Brazilian industrial firms on the world stage. For this, questionnaires were applied to 93 companies linked to ANPEI, all of them large. Getting a 48% response rate could be doing a good relationship and analysis of cases to which it was intended to verify.
A responsabilidade social das empresas é um tema atual e, nos últimos anos, vem sendo consolidada à crença que as empresas devem assumir um papel mais amplo perante a sociedade que não somente o de maximização de lucro e criação de riqueza. A partir desses pressupostos, o estudo busca analisar o impacto da adoção de estratégias de negócios sustentáveis no desempenho de empresas industriais brasileiras. As conclusões do estudo deverão corroborar com o desenvolvimento de um modelo de excelência de gestão classe mundial alinhado às exigências internacionais que garantam o ingresso e a manutenção de empresas industriais brasileiras no cenário mundial. Para isto, foram aplicados questionários à 93 empresas associadas a ANPEI, todas elas de grande porte. Obtendo um índice 48% de respostas conseguiu-se fazer uma boa relação e análise das hipóteses ao qual se era proposto verificar.

Abstract:

La détection participative est un nouveau paradigme dans lequel les citoyens utilisent volontairement leur téléphone portable pour capturer et partager les données détectées deleur environnement afin de surveiller et d'analyser certains phénomènes. Divers systèmes de réputation ont été proposés pour surveiller le comportement des participant’s dans lesapplications de détection participative afin d'identifier ceux qui fournissent de mauvaises contributions. Cependant, les systèmes de réputation existants ne fournissent pas de garanties de confidentialité aux contributeurs. Ainsi, les utilisateurs hésitent généralement à se joindre à des campagnes de détection participatives car ils sont invités à fournir leurs données détectées, notamment l'heure, l'emplacement, etc. Il a été démontré dans différents travaux que jusqu'à 95% de l'identité des participants peut être réidentifiée par le partage de quatre. Contributions contenant des données multi-capteurs. Pour cette raison, l'intégration entre les systèmes de protection de la vie privée et les systèmes de reputation est un besoin crucial pour la création d'applications de détection participative sécurisées et fiables. Cette intégration nécessite la garantie d'objectifs apparemment contradictoires. En effet, les systèmes de réputation surveillent les comportements des participants tout au long des interactions. Alors que l'objectif des systèmes de préservation de la vie privée est de dissocier le lien entre les interactions ultérieures. Dans cette thèse, nous étudions des stratégies possibles pour intégrer des systèmes préservant la confidentialité dans des systèmes sensibles à la réputation. Cette intégration poseun nouveau défi en matière de vie privée en raison de la contradiction entre leurs objectifs. Ensuite, une nouvelle attaque a été définie (attaque RR). L'attaque RR exploite cette contradiction pour détecter la succession des contributions fournies par le même participant. Ensuite, un nouveau protocole préservant la confidentialité (PrivaSense) est proposé. PrivaSense définit une méthode qui garantit à la fois la confidentialité et la réputation et résout simultanément leur contradiction. Enfin, nous proposons un nouveau système de réputation DTSRS, qui repose sur un ensemble de participants fiables pour évaluer la réputation des participants. DTSRS introduit de nouvelles mesures pour évaluer la confiance des contributions des participants. DTSRS a la capacité de se défendre plus fortement contre un ensemble d'attaques qui n'ont pas été considérées dans la littérature (par exemple, Collision, On-off, etc.). DTSRS permet au serveur d'applications d'agréger les données plus précisément. De plus, le DTSRS évalue correctement la confiance et la réputation même si un grand nombre d'adversaires sont inclus dans la campagne de détection
Participatory sensing is an emerging paradigm in which citizens voluntarily use their mobile phones to capture and share sensed data from their surrounding environment in order to monitor and analyze some phenomenon. Various reputation systems have been proposed to monitor participants' behavior in participatory sensing applications in order to identify those who provide bad contributions. However, the existing reputation systems do not provide privacy guarantees to the contributors. Thus, users usually hesitate to join participatory sensing campaigns since they are asked to provide their sensed data including time, location, etc. It has been shown in different works that up to 95% of participants’ identities can be re-identified through sharing four contributions containing multi-sensor data. Due to this reason, the integration between privacy preserving systems and reputation systems is a crucial need for building secure and reliable participatory sensing applications. This integration requires the assurance of seemingly conflicting objectives. Indeed, reputation systems monitor participants’ behaviors along subsequent interactions. Whereas, the objective of privacy preserving systems is to in fact detach the link between subsequent interactions. In this thesis, we study possible strategies to integrate privacy preserving systems within reputation-aware systems. This integration raises a new privacy challenge because of the contradiction between their objectives. Then, a new attack has been defined (RR attack). RR attack exploits this contradiction in order to detect the succession of contributions provided by the same participant. Next, a new privacy preserving reputation-aware protocol (PrivaSense) is proposed. PrivaSense defines a method that ensures both privacy and reputation and simultaneously solves their contradiction. Finally, we propose a novel reputation system DTSRS, which depends on a set of the most trusted participants in order to assess the reputation of participants. DTSRS introduces new measures to evaluate the trust of participants' contributions. DTSRS has the ability to defend more strongly against a set of attacks that was not considered in the literature (e.g. Collision, On-off, etc.). DTSRS enables the application server to aggregate the data more accurately. Moreover, DTSRS assesses both trust and reputation correctly even if a large number of adversaries are included in the sensing campaign

Mestrado em Marketing
Com a evolução do mercado de ebooks e do marketing, muitas empresas começaram a utilizar uma estratégia de inbound marketing baseada na gratificação de ebooks em troca do contato de potenciais clientes. Nesse contexto, a presente investigação se baseou na teoria dos usos e gratificações para compreender se a motivação para fazer downloads de ebooks influencia a reputação percecionada da marca e a decisão de compra do consumidor. Para isso, foi feita uma pesquisa quantitativa com uma amostra não probabilística por conveniência, tendo sido obtidas 612 respostas válidas através da aplicação de um questionário online a maiores de 18 anos que fizeram o download de algum ebook, pelo menos, uma vez no último ano. Com a execução da pesquisa foi possível identificar 9 motivações para o download de ebooks e descobrir que essas motivações podem ser divididas em 2 grupos, o das motivações profissionais e o das motivações lúdicas. Além disso, foram encontrados resultados estatisticamente significativos indiciadores da influência positiva desses 2 grupos de motivações na reputação da marca e das motivações lúdicas na decisão de compra do consumidor. Adicionalmente, confirmou-se a influência positiva da reputação da marca na decisão de compra. Os resultados apurados podem ser relevantes para académicos que queiram estudar a teoria dos usos e gratificações em contextos digitais e, na perspetiva das organizações, ajudar a decidirem se devem optar por essa estratégia de inbound marketing.
With the evolution of the ebook market and marketing, many companies have started to use an inbound marketing strategy that consists on giving a free ebook as gratification in exchange for contact information of potential customers. In this context, this research was based on the uses and gratifications theory to understand whether the motivation to download free ebooks influences the perceived reputation that the customers have about the brand and influences their purchase decision. Quantitative research was performed, using a non-probabilistic and convenience sample. A total of 612 valid responses were obtained through the application of an online questionnaire to people over 18 years old, who had downloaded an ebook at least once in the last year. With the execution of this research, it was possible to identify 9 motivations for downloading ebooks and discover that these motivations can be divided into 2 groups, the professional motivations and the recreational motivations. In addition, statistically significant results were found in the positive influence of these 2 groups of motivation on the reputation of the brand and the recreational motivations in the consumer's purchase decision. Additionally, the positive influence of the reputation of the brand on the purchase decision was confirmed. With the results of this research, it is possible to assist academics who want to study the uses and gratifications theory in digital contexts and, from the perspective of organizations, help them decide if it is a good idea adopt this inbound marketing strategy.

Mestrado em Marketing
A reputação pode ser vista como um conjunto das perceções dos stakeholders, que refletem tanto a imagem como a identidade da organização (Davies, Chun, Silva, & Roper, 2001). A presença do líder como referência principal nas organizações e a possibilidade da sua reputação estar associada à reputação da organização que lidera tem sido objeto de estudo, nem sempre conclusivos. Esta dissertação pretende compreender se existe uma associação entre a reputação do líder e a reputação da empresa que o mesmo lidera. Estuda-se essa associação no contexto empresarial de três organizações - Facebook, Instagram e WhatsApp, detidas pela mesma pessoa - Mark Zuckerberg. É utilizada a perspetiva de reputação de Davies, Chun, Silva e Roper (2001) e o instrumento de medida é a Escala de Carácter Corporativo. Foi realizado um estudo quantitativo, com uma amostra por conveniência, através de um inquérito por questionário aplicado online com 304 respostas válidas. Os resultados obtidos indicam que existe uma possível relação entre a reputação do líder e a reputação da empresa que lidera, uma vez que, apesar das perceções de reputação não serem idênticas, existe uma correlação positiva entre ambas, no qual se realçam as dimensões de empreendedorismo, sofisticação e concordância.
Reputation can be argued as a collective perception, created by the stakeholders, which combines an organisation's image and identity (Davies, Chun, Silva, & Roper, 2001). The leader's presence, as the main reference of an organisation, and the probability that their reputation may influence corporate reputation, has been studied and claimed in some, and sometimes, not conclusive researches. This dissertation aims to understand the relationship between the leader's reputation and corporate reputation. To study the link between both reputations, three companies - Facebook, Instagram and WhatsApp, hold by the same leader - Mark Zuckerberg, were assessed. A quantitative analysis was undertaken using the reputation concept and Corporate Character Scale of Davies, Chun, Silva and Roper (2001), as a measuring instrument. Through an online questionnaire, and a convenience sampling, 304 valid responses were obtained. Although the perception of both reputations were not identical, the results indicate that there is a possible relationship between the leader's reputation and corporate reputation due to the positive correlation between them, focusing on the high correlation levels of the dimensions: enterprise, chic and agreeableness.

Abstract:

Image sur le web : analyse de la dynamique des images sur le Web 2.0. En plus d’être un moyen d’accès à la connaissance, Internet est devenu en quelques années un lieu privilégié pour l’apparition et la diffusion d’opinions.Chaque jour, des millions d’individus publient leurs avis sur le Web 2.0 (réseaux sociaux, blogs, etc.). Ces commentaires portent sur des sujets aussi variés que l’actualité, la politique, les résultats sportifs, biens culturels, des objets de consommation, etc. L’amoncellement et l’agglomération de ces avis publiés sur une entité (qu’il s’agisse d’un produit, une entreprise ou une personnalité publique)donnent naissance à l’image de marque de cette entité.L’image d’une entité est ici comprise comme l’idée qu’une personne ou qu’un groupe de personnes se fait de cette entité. Cette idée porte a priori sur un sujet particulier et n’est valable que dans un contexte, à un instant donné.Cette image perçue est par nature différente de celle que l’entité souhaitait initialement diffuser (par exemple via une campagne de communication). De plus,dans la réalité, il existe au final plusieurs images qui cohabitent en parallèle sur le réseau, chacune propre à une communauté et toutes évoluant différemment au fil du temps (imaginons comment serait perçu dans chaque camp le rapprochement de deux hommes politiques de bords opposés). Enfin, en plus des polémiques volontairement provoquées par le comportement de certaines entités en vue d’attirer l’attention sur elles (pensons aux tenues ou déclarations choquantes), il arrive également que la diffusion d’une image dépasse le cadre qui la régissait et même parfois se retourne contre l’entité (par exemple, «le mariage pour tous» devenu « la manif pour tous »). Les opinions exprimées constituent alors autant d’indices permettant de comprendre la logique de construction et d’évolution de ces images. Ce travail d’analyse est jusqu’à présent confié à des spécialistes de l’e-communication qui monnaient leur subjectivité. Ces derniers ne peuvent considérer qu’un volume restreint d’information et ne sont que rarement d’accord entre eux. Dans cette thèse, nous proposons d’utiliser différentes méthodes automatiques, statistiques, supervisées et d’une faible complexité permettant d’analyser et représenter l’image de marque d’entité à partir de contenus textuels les mentionnant. Plus spécifiquement, nous cherchons à identifier les contenus(ainsi que leurs auteurs) qui sont les plus préjudiciables à l’image de marque d’une entité. Nous introduisons un processus d’optimisation automatique de ces méthodes automatiques permettant d’enrichir les données en utilisant un retour de pertinence simulé (sans qu’aucune action de la part de l’entité concernée ne soit nécessaire). Nous comparer également plusieurs approches de contextualisation de messages courts à partir de méthodes de recherche d’information et de résumé automatique. Nous tirons également parti d’algorithmes de modélisation(tels que la Régression des moindres carrés partiels), dans le cadre d’une modélisation conceptuelle de l’image de marque, pour améliorer nos systèmes automatiques de catégorisation de documents textuels. Ces méthodes de modélisation et notamment les représentations des corrélations entre les différents concepts que nous manipulons nous permettent de représenter d’une part, le contexte thématique d’une requête de l’entité et d’autre, le contexte général de son image de marque. Nous expérimentons l’utilisation et la combinaison de différentes sources d’information générales représentant les grands types d’information auxquels nous sommes confrontés sur internet : de long les contenus objectifs rédigés à des informatives, les contenus brefs générés par les utilisateurs visant à partager des opinions. Nous évaluons nos approches en utilisant deux collections de données, la première est celle constituée dans le cadre du projet Imagiweb, la seconde est la collection de référence sur le sujet : CLEFRepLab
Analyse of entities representation over the Web 2.0Every day, millions of people publish their views on Web 2.0 (social networks,blogs, etc.). These comments focus on subjects as diverse as news, politics,sports scores, consumer objects, etc. The accumulation and agglomerationof these notices on an entity (be it a product, a company or a public entity) givebirth to the brand image of that entity. Internet has become in recent years aprivileged place for the emergence and dissemination of opinions and puttingWeb 2.0 at the head of observatories of opinions. The latter being a means ofaccessing the knowledge of the opinion of the world population.The image is here understood as the idea that a person or a group of peopleis that entity. This idea carries a priori on a particular subject and is onlyvalid in context for a given time. This perceived image is different from theentity initially wanted to broadcast (eg via a communication campaign). Moreover,in reality, there are several images in the end living together in parallel onthe network, each specific to a community and all evolve differently over time(imagine how would be perceived in each camp together two politicians edgesopposite). Finally, in addition to the controversy caused by the voluntary behaviorof some entities to attract attention (think of the declarations required orshocking). It also happens that the dissemination of an image beyond the frameworkthat governed the and sometimes turns against the entity (for example,« marriage for all » became « the demonstration for all »). The views expressedthen are so many clues to understand the logic of construction and evolution ofthese images. The aim is to be able to know what we are talking about and howwe talk with filigree opportunity to know who is speaking.viiIn this thesis we propose to use several simple supervised statistical automaticmethods to monitor entity’s online reputation based on textual contentsmentioning it. More precisely we look the most important contents and theirsauthors (from a reputation manager point-of-view). We introduce an optimizationprocess allowing us to enrich the data using a simulated relevance feedback(without any human involvement). We also compare content contextualizationmethod using information retrieval and automatic summarization methods.Wealso propose a reflection and a new approach to model online reputation, improveand evaluate reputation monitoring methods using Partial Least SquaresPath Modelling (PLS-PM). In designing the system, we wanted to address localand global context of the reputation. That is to say the features can explain thedecision and the correlation betweens topics and reputation. The goal of ourwork was to propose a different way to combine usual methods and featuresthat may render reputation monitoring systems more accurate than the existingones. We evaluate and compare our systems using state of the art frameworks: Imagiweb and RepLab. The performances of our proposals are comparableto the state of the art. In addition, the fact that we provide reputation modelsmake our methods even more attractive for reputation manager or scientistsfrom various fields

Abstract:

Los conceptos de confianza y reputación determinan un campo de investigación relevante para varias disciplinas científicas. Desde el punto de vista de las Ciencias de la Computación, una gran parte de los esfuerzos en esta dirección se ha dedicado a la definición de mecanismos de control adaptativos de las comunidades virtuales tomando como referencia las relaciones que se presentan en las sociedades humanas. El hecho de tener en cuenta elementos asociados a la confianza y la reputación contrarresta el elevado grado de incertidumbre bajo el cual los individuos toman sus decisiones. Así, un modelo de confianza y reputación hace frente a la incertidumbre asociada a las decisiones que toman las partes "inteligentes" de varios tipos de sistemas. En este sentido, resulta importante proporcionar algunos mecanismos de estimación de los valores de confianza y reputación que permitan ofrecer recomendaciones valiosas aun cuando no se disponga de la información suficie nte para hacerlo. También destaca la necesidad de adopción de algún modelo conceptual común y eficaz para la representación de los elementos dependientes del dominio de aplicación.Esta tesis está dedicada a la definición y estudio de un modelo de confianza y reputación que, adoptando un marco de representación ontológica para la definición de los elementos dependientes del dominio de aplicación, utiliza criterios de similitud para estimar el desempeño de las partes del sistema cuando la información relacionada se presenta incompleta. Se estudia el comportamiento del modelo para diferentes alternativas de definición de algunos de sus elementos, y frente a diferentes situaciones experimentales, determinadas por las variaciones del desempeño de los elementos del sistema.
. The concepts of trust and reputation determine an important research field for several scientific disciplines. From the point of view of Computer Sciences, a large amount of efforts in this direction has been devoted to the definition of adaptive control mechanisms for virtual communities based on the relationships that take place in human societies. Taking into account some elements associated with trust and reputation, the high degree of uncertainty, under which individuals make decisions, is reduced. Thus, a trust and reputation model could help to deal with the uncertainty associated with the decisions of "smart" parties, in some types of systems.This way, it is important to provide some mechanism to estimate the trust and reputation values in order to give valuable recommendations, even if there are no sufficient information to do so. It also stands out the necessity to adopt a common and effective conceptual model for the representation of the application doma in elements.This thesis is devoted to the definition and study of a trust and reputation model, based on a common ontological framework for the definition of domain-dependent elements, using similarity criteria for estimating the performance of parts of the system when related information is incomplete. Also it analyzes the behavior of the model to different alternatives for the definition of some of its elements, and in front of different experimental situations, determined by variations in the performance of the system elements.

Nowadays, peer-to-peer networks are very popular mainly, when we wish to search or share a considerable amount of information and resources among various participants. One of the main difficulties of this technology is how to avoid that those participants maintain, at the same time, a considerable number of shared resources and to guarantee that those resources are not corrupted or polluted content. Another problem commonly found in P2P networks is the lack of interoperability among existing P2P solutions especially because the inconsistencies of metadata and operation interfaces used in node communication. This work describes P2PWSRep, a reputation management protocol that identifies non-cooperative nodes or that can hinder network performance by sharing corrupted, infected or non-existent files. P2PWSRep infrastructure was based on web services in order to tackle interoperability problems and to facilitate its extensibility, making it feasible to be accessed by several other P2P applications. The P2PWSRep protocol employs a distributed reputation computation using an exponentially weighted average that takes into account the current and previous node reputation and which is tuned by an adjustment parameter in order to obtain the final reputation, thus considering the node s behavior. The P2PWSRep protocol is validated by means of simulation and our results show that it is able to point out the more trustable nodes in the network as well as to insulate those which are not reliable or cooperative. Besides, the protocol does not unnecessarily impacts on the network load P2PWS.
As redes peer-to-peer (P2P) são muito populares atualmente, principalmente quando se deseja buscar ou compartilhar uma grande quantidade de informações e recursos entre os seus participantes. Uma das grandes dificuldades desse tipo de tecnologia é evitar que esses participantes mantenham, ao mesmo tempo, um número considerável de arquivos compartilhados, e ainda garantir que esses arquivos não sejam conteúdo poluído ou corrompido. Outro problema bem comum nas redes P2P, é a falta de interoperabilidade entre as diversas redes existentes, principalmente devido às incompatibilidades dos metadados e das interfaces das operações utilizadas na comunicação entre os nós. Este trabalho descreve o P2PWSRep, um protocolo de gerenciamento de reputação para identificar nós que não desejam cooperar ou que podem prejudicar o desempenho da rede pelo compartilhamento de arquivos corrompidos, infectados ou inexistentes. A infraestrutura da rede do P2PWSRep foi baseada em serviços web para contornar problemas de interoperabilidade e facilitar sua extensibilidade, tornando-o fácil de ser utilizado por diversas aplicações de redes P2P. O protocolo P2PWSRep possui um cállculo de reputação distribuído, utilizando-se uma média ponderada exponencial, que considera o valor da reputação anterior do nó e o valor atual, obtido dos demais nós da rede, e regulado por um parâmetro de ajuste, para obter a reputação final, de forma que o histórico do comportamento do nó seja considerado. O protocolo P2PWSRep é validado por meio de simulação e os resultados obtidos mostram que o mesmo é capaz de apontar os nós ou recursos mais confiáveis da rede, ao mesmo tempo em que isola aqueles nós que não são íntegros ou pouco cooperativos, além de não impor uma sobrecarga desnecessária à rede P2PWS.

Abstract:

Šio darbo tikslas yra nustatyti veiksnius, kurie įtakoją organizacijos reputaciją. Siekiant darbo tikslų atskleidimo iš pradžių buvos analizuojamos diferencijuotos ir analoginės mokyklų autorių mintys, ko pasėkoje buvo prieita prie teoretikų kaip Balmer, Bromley, Fombrun (diferencijuotos mokyklos atstovai), reputacijos koncepcijos, kuri pažymi, kad organizacijos reputacija yra įmonės ankstesnių veiksmų ir pasekmių atspindys, kuris parodo organizacijos gebėjimą paskirstyti rezultatą publikai. Ji laiko atžvilgiu yra ilgalaikiškesnė nei įvaizdis. Tuo tarpu įvaizdis gali būti greitai keičiamas ir melagingas, be to reputacija yra siejama publikos patirtimi su organizacija. Darbe taip pat atlikta organizacijos įvaizdžio ir identiteto koncepcijų analizė bei palyginimas su organizacijos reputacija, kadangi šios sąvokos yra glaudžiai susijusios ir dažnai painiojamos tarpusavyje. Organizacijos įvaizdis tai vidinės ir išorinės organizacijos publikos nuomonių bei pažiūrų visuma, o įmonės identitetas yra organizacijos savęs pristatymas, priklausantis nuo charakteristikų, kurios organizaciją pateikia savo elgesio pavyzdžiu, simbolių ir ryšių pagalba. Esminis skirtumas tarp šių koncepcijų yra tas, kad organizacijos identitetas tai būdas, kuriuo organizacijos nariai vertina savo organizaciją, įvaizdis tai būdas, kuriuo organizacija prisistato visuomenei ir reputacija tai būdas kuriuo visuomenė vertina organizaciją. Remiantis „Financial times“ bei „Fortune“, išskirti šeši pagrindiniai... [toliau žr. visą tekstą]
The aim of this paper is to demonstrate the factors that have an influence over the reputation of organization. In order to achieve the goals of the paper the analysis of the authors’ thoughts from differential and analog schools has been made. The outcome of Balmer, Bromley, Fombrun (the representatives of differential school) is the concepts of reputation that signify that the reputation of organization is the result of past actions and that shows the capability of organization to allocate the result to the public. Reputation is more sustained than the image in terms of time. In addition image can be changed quickly and can be untrue; reputation on the other hand is more associated with the experience of organization. The analysis of organizational image and identity concepts has been made and a comparison with organizational reputation has been done. This has been done because these two concepts are associated and sometimes understood as synonyms. The image of organization is the summation of the inner and external public opinions; the identity is the presentation of organization, dependable on the characteristics that represent the organization by using symbols, examples and communications. The main difference between these concepts is that the identity of organization is a mean by which the members of organization value the organizations; the image is a mean by which organization presents itself to the society; reputation is a mean by which the society values the...

CAPES - Coordenação de Aperfeiçoamento de Pessoal de Nível Superior
A importância dos softwares nas organizações é crescente. No entanto, para manter seu valor, o software deve ser alterado e atualizado. A manutenção de software depende da alocação de recursos humanos para o cumprimento das atividades de alteração definidas. Entretanto, em um cenário distribuído no qual a colaboração é fundamental para o bom funcionamento das atividades, torna-se uma tarefa não trivial designar desenvolvedores para as atividades de manutenção. Neste contexto, a reputação se torna um elemento chave, afetando os elementos de colaboração, tais como: a coordenação, a cooperação, e a comunicação. Portanto, o acompanhamento da evolução da reputação é importante para promover a colaboração nas atividades de manutenção. A teoria de Dinâmica de Sistemas pode ser aplicada no acompanhamento da evolução da reputação. Através dos dados obtidos, é possível compreender o passado, estabelecer o que ocorre no presente e projetar o comportamento futuro da reputação. Diante disso, este trabalho apresenta um modelo para cálculo da reputação dos desenvolvedores de software, apoiado por técnicas de Dinâmica de Sistemas, o qual permite simular como a reputação se comporta ao longo do tempo. Este modelo serviu de base para a construção de uma infraestrutura para informações de reputação dinâmica, cujo objetivo é possibilitar o gerenciamento e acompanhamento de informações de reputação dos desenvolvedores geograficamente distribuídos de forma a apoiar a alocação desses desenvolvedores às tarefas de manutenção. Além disso, oferece elementos de visualização e colaboração, em um ambiente integrado às atividades de manutenção de software. Uma prova de conceito e um experimento realizados com dados reais de uma empresa são apresentados com o intuito de identificar a viabilidade e aderência do modelo proposto, bem como dos demais recursos oferecidos pela infraestrutura.
The importance of software in organizations is growing. However, to maintain its value, the software must be changed and updated. Software maintenance depends on the allocation of human resources to fulfill defined change activities. However, in a distributed scenario in which collaboration is critical to the well running of activities, designate developers for maintenance activities becomes a non-trivial task. In this context, reputation becomes a key element, affecting elements of collaboration, such as: coordination, cooperation, and communication. Therefore, tracking reputation evolution is important to promote collaboration in maintenance activities. The theory of System Dynamics can be applied in monitoring the evolution of reputation. Through the data obtained, it is possible to understand the past, establish what occurs in the present, and project future reputation behavior. Therefore, this work presents a model for calculating the reputation of software developers, supported by System Dynamics techniques, which allows simulating how reputation behaves over time. This model served as the basis for building an infrastructure for dynamic reputation information, which aims to enable the management and tracking reputation information of geographically distributed developers to support the allocation of these developers to maintenance tasks. In addition, it provides visualization and collaboration elements in an integrated environment for software maintenance activities. A proof of concept and an experiment made with real data of a company are presented with the intention of identifying the feasibility and adherence of the proposed model, as well as of the other resources offered by the infrastructure.

Abstract:

Mestrado em Marketing
O construto da reputação tem-se revelado complexo e tem sido olhado sob diversas perspectivas. De acordo com Davies et al (2003), a reputação engloba uma perspectiva interna (identidade) e uma perspectiva externa (imagem), que correspondem à visão dos colaboradores e dos clientes, respectivamente. Os autores criaram uma escala que permite medir ambas as perspectivas em simultâneo e ainda explorar a ligação da reputação com outros conceitos como satisfação e lealdade. Neste estudo, pretende-se compreender a reputação no contexto das profissões. Os principais objectivos são: (1) aferir a reputação da profissão de gestor e de marketeer, quando percepcionada pelos alunos de uma instituição académica; (2) verificar se existem diferenças na percepção da reputação de cada uma das profissões entre alunos que pretendam exercê-las no futuro e entre os restantes alunos; e (3) comparar a reputação das duas profissões quando percepcionada pelo total de alunos. Este estudo, de carácter exploratório, recorreu ao método quantitativo, através do inquérito por questionário a uma amostra não probabilística de 247 alunos de uma instituição de ensino superior. A Escala de Carácter Corporativo (Davies et al, 2003) foi o instrumento utilizado para medir a reputação. Os resultados obtidos permitem concluir que: (1) no geral, os alunos atribuem às profissões de gestor e de marketeer reputações positivas; (2) não se verificam diferenças significativas quanto à reputação da profissão de gestor entre os grupos de alunos considerados, mas existem diferenças em relação à reputação da profissão de marketeer; e (3) entre as duas profissões, verificam-se diferenças significativas na reputação percepcionada pelos alunos.
The reputation has revealed itself as a complex construct and has been seen under different perspectives. According to Davies et al (2003), it includes an internal view (identity) and an external view (image), that correspond to the employees and students' perspectives, respectively. These authors created a scale that measures both perspectives simultaneously and explores the links between reputation and other concepts such as satisfaction and loyalty. In this study, we intend to understand reputation in the professions' context. The main objectives are: (1) assess the manager and marketeer professions' reputation from the perspective of university students; (2) verify the differences between future professionals and other students' perceptions; and (3) compare both professions' reputation as perceived by all students. This is an exploratory research that used the quantitative approach through a survey applied to a non-probabilistic sample of 247 students of an academic institution. The Corporate Character Scale (Davies et al, 2003) was used to measure reputation. It was possible to conclude that: (1) in general, students hold a positive reputation of manager and marketeer professions; (2) there are no significative differences between distinct targets' perceptions about the manager profession, but in the marketeer profession there are significant differences; and (3) between both professions, there are significative differences in the reputation perceived by the whole sample of students. Study limitations and suggestions for future research are also presented.

Abstract:

Cette recherche-action menée au sein de la DSIC de La Poste s’intéresse à la réputation des organisations et à son pendant numérique (l’e-réputation) par le prisme des sciences de l’information-communication. Elle propose le développement d’un processus et d’un dispositif de veille stratégique par infomédiation sociale permettant à une organisation d’évaluer, de gérer et in fine de construire son e-réputation.Dans un premier temps, nous présentons un cadre théorique de la réputation des organisations comme objet info-communicationnel. Puis nous abordons l’e-réputation (ou réputation en ligne) des organisations comme une information stratégique constituée de l’ensemble des indicateurs issus de la commensuration des interactions intentionnelles endogènes ou automatisées des communautés virtuelles avec l’organisation : productions d’opinions, notations ou encore agir des publics.Dans un deuxième temps, nous nous questionnons sur les moyens à disposition du groupe La Poste pour construire cette e-réputation. Par « construction », nous entendons la manière de structurer l’environnement informationnel dans lequel les publics de l’organisation évoluent chaque jour sur le web dit social, et plus spécifiquement sur la plate-forme Twitter. Dans ce cadre, nos observations empiriques nous permettent de mettre en exergue, de questionner et d’analyser des utilisateurs du web dont les pratiques informationnelles nous amènent à les qualifier « d’agents-facilitateurs », et dont la caractéristique principale est de participer à la prescription informationnelle et à la médiation documentaire sur le web.Suite à l’observation de certains de ces agents et à la production d’une typologie, nous proposons un modèle et un processus de veille les intégrant. Processus dont les résultats opérationnels au sein de La Poste mettent en avant la nécessaire prise en compte et analyse des pratiques de recommandation des internautes au sein des réseaux socionumériques afin que l’organisation construise son e-réputation de manière proactive
This research within La Poste's DSIC is focused on corporate reputation and on e-reputation through the prism of information and communication sciences. It proposes the development of a web monitoring and a social search process enabling to assess, manage and build online reputation.At first, we present a theoretical framework for corporate reputation as an info-communicational object. Then we discuss corporate e-reputation such as a strategic information made up of all commensuration indicators constituted by intentional (endogenous or not) interactions with the virtual communities and the firm : productions of opinions, assessment or public behavior.In a second step, we investigate how La Poste group can build its e-reputation. By "build" we mean the way to structure the informational environment where customers evolve each day on social web, and more specifically on the Twitter platform. In this context, our empirical observations allow us to highlight, question and analyze, web users whose informational practices permit us to qualify of "facilitators-agents", and whose main characteristic is to participate in informational prescription and the documentary mediation on the web.After the observation of some of these agents and the production of a typology, we propose a model and a monitoring process to integrate them. Our process's results in La Poste show the need to take into account and analyse recommendation practices on social networks to build corporate e-reputation proactively

Service-based communication is becoming increasingly relevant, as seen in the Internet of Things scenarios. Choosing an adequate service however can be a difficult task, as this form of communication may involve sensible resources and data. A trustworthy, safe, and privacy preserving mechanism is desirable for service selection. Reputation systems can help in this selection. This thesis presents a reputation system for service selection based on the security and privacy mechanisms of crypto-coins. In order to evaluate the performance of the proposed mechanism in the identification of low quality service providers we also investigated the use of different formulations used to determine a reputation based on peer voting. Results from simulation show the proposed system architecture is viable and supports large adoption via a scalable infrastructure. The performance analysis of different formulations for the calculus of reputations also shows that the recent behavior of an entity is the most impacting factor in establishing its reputation.
A comunicação por meio de serviços tem se tornado cada vez mais relevante, como em cenários da Internet das Coisas. A escolha entre serviços, contudo, pode ser uma tarefa difícil, já que essa forma de comunicação pode envolver recursos e dados sensíveis. Assim, é preciso um sistema de seleção de serviços que seja confiável, seguro e privado, garantindo que as expectativas dos utilizadores dos serviços sejam alcançadas. Sistemas de reputação podem ajudar nessa seleção. Assim, este trabalho apresenta um sistema de reputação distribuído para avaliação de interações baseadas em serviços utilizando conceitos da arquitetura de sistemas das cripto moedas. Para avaliar o desempenho na detecção de serviços de baixa qualidade utilizando o mecanismo proposto, apresenta-se também um estudo do comportamento de diferentes formulações para o cálculo de reputações. Resultados obtidos via simulação mostram que a arquitetura do sistema de reputação proposto é viável e permite uma ampla adoção com uma infraestrutura escalável. A análise do comportamento das formulações também permite concluir que o histórico recente do comportamento dos elementos avaliados é o fator que mais influencia na qualificação dos dispositivos.

Relatório Profissional para obtenção de grau de Mestre em Comunicação Social, vertente de Comunicação Estratégica
As organizações, pelo papel que exercem na sociedade, são importantes fontes de informação e têm o direito e o dever de prestar contas das suas ações aos seus públicos. O relacionamento que desenvolvem com os meios de comunicação social não deve, por isso, restringir-se à divulgação dos seus produtos e serviços. As organizações devem assumir, de igual forma, uma responsabilidade pública enquanto fontes de informação. Considera-se, assim, pertinente analisar neste trabalho, a importância da construção de um relacionamento eficaz entre organizações e media, como estratégia para o fortalecimento de uma imagem. No presente relatório é apresentada uma descrição detalhada da atividade profissional desenvolvida pela mestranda, desde o término da licenciatura em Ciências da Comunicação- Ramo Comunicação Social / Jornalismo (1998-2003) até à presente data e o tipo de competências adquiridas. O percurso profissional realizado assentou numa estreita relação entre Jornalismo e Comunicação Organizacional, o que motivou a escolha do tema "Comunicação Organizacional: o relacionamento com os media", que será desenvolvido no capítulo dois, como enquadramento teórico-temático à experiência profissional adquirida.
For the role they play in society, organizations are important sources of information and have the right and the duty to answer for their actions to their public. The relationship they develop with the media should not, therefore, be restricted to the dissemination of their products and services. Organizations must assume, similarly, a public responsibility as sources of information. It is therefore relevant to examine in this report, the importance of building effective relationships between organizations and media, as a strategy to strengthen an image. This report presents a detailed description of the professional activity carried out by the master student, since completion of the degree in Sciences of Communication, Media / Journalism (1998-2003) until today and the type of skills acquired. The accomplished career was based on a close relationship between Journalism and Organizational Communication, which motivated the choice of the topic "Organizational Communication: the relationship with the media," which will be developed in chapter two, as the theoretical framework to the professional experience.

Abstract:

Reputação tornou-se, no contexto contemporâneo, um valor que norteia os discursos e as atitudes de organizações e indivíduos na contemporaneidade. Para as organizações capitalistas tornou-se um ativo de geração e manutenção do seu valor de capital numa ambiência cada vez mais orientada pela intangibilidade, imaterialidade e no entendimento das significações produzidas pelos variados sujeitos contemporâneos integrados pelas redes de relacionamento virtuais suportadas pelas Tecnologias de Informação e Comunicação-TICs. O grande objeto tranformador dessa realidade, a comunicação, tornou-a um instrumento de poder e validador de legitimidade, inclusão ou exclusão. Ela tornou-se processo, saindo de sua ação funcional para exercer àquela demandada pelas organizações: a de agente de interação, entendimento e do nível de porosidade interna do entendimento das significações e demandas do ambiente externo. A pesquisa conduzida neste estudo projeta reputação sob as interpretações e as essências surgidas das falas dos sujeitos gestores das organizações, das classes e daqueles em interação em ambiente virtual de uma rede colaborativa, comparadas à norma e ao discurso global do Reputation Institute. Buscou-se entendimento sob a ótica dos individuos gestores da Comunicação e da Comunicação bem como das classes que os representam. Procurou-se tambem entender como o termo se manifesta na contemporaneidade, a partir do levantamento dos estudos produzidos no Brasil e em quais campos eles mais são produzidos. Com relação aos sujeitos organizacionais foram considerados os da gestão da Comunicação Corporativa, da gestão de Marca e Comunicação Institucional e da gestão de Relação com Investidores do Itaú- Unibanco; o gestor de Marketing/Comunicação e do negócio da Lecom-Comunicação Digital; da Comunicação Corporativa da SAP Brasil; representantes da Abracom-Associação Brasileira das Agências de Comunicação, do Conrerp/Sudeste/Sul-Conselho Regional de Relações Publicas e do IBRI-Instituto Brasileiro de Relações com Investidores. Reputação se manifesta, na pesquisa, como norma. Ela apresenta indicadores para uma gestão diferenciada de reputação, a partir das essências dos sujeitos participantes. Como norma, reputação se mostra como instrumento que assegura o controle de comportamentos de forma a alinhar práticas e discursos e atitudes que garantam confiança e credibilidade de acionistas, investidores, publicos de relacionamento e da sociedade. Na integração de todos os sujeitos, o estudo mostrou que é possível a arquitetura de um modelo gestor de reputação integrador sustentado nas variaveis humanas, que leve à evolução de todos os sujeitos a partir dos valores e normas que permeiam cada agrupamento e a partir do qual gera confiança e pode tornar a organização referencial de construção de novos valores e padrões normativos integrados
Reputation has become in a contemporary context, a value that guides speeches and attitudes of organizations and individuals in the contemporary present. For capitalist organizations it has turned in an asset of generation and maintenance of its capital value in an ambience of increasing orientation by intangibility, immateriality and understanding of meanings produced by varied contemporary actual subjects integrated by virtual relationships networks supported by Communication and Information Technologies - CITs. The great transforming object of this reality, the communication, it made the communication an instrument of power and a legitimacy, inclusion or exclusion validator. It has changed to a process, moving from its functional action role to perform those demanded by organizations such as: agent of interaction, and of the level of understanding internal porosity of the meanings and demands of the external environment. The research led in this tesis highlights reputation under interpretations and essences extracted from organizations managing subjects, their representative classes and those interacting in a collaborative virtual environment network speeches, compared to the standard and the global discourse of the Reputation Institute. The understanding was based on the perspective of Communication and the Capital Management individuals. Also sought to understand how the term is manifested (expressed) in contemporary times currently, based on the researches produced in Brazil and in which fields they are produced more , available in the research environment google. Regarding to organizational subjects this reseach considered the Management of Corporate Communications , Brand and Corporate Communications Management and Management Itaú Unibanco Investors Relationship; Manager of Marketing /Communications and Business of Lecom - Comunicação Digital; Corporate Communication of SAP Brazil; representatives of Abracom - Associação Brasileira das Agências de Comunicação; CONRERP / South East / Southern -Conselho Regional de Relações Públicas and IBRI - Instituto Brasileiro de Relações com Investidores. Reputation is manifested in the research as a norma. It presents elements for a noteworthy reputation management, based on the essences of the participating subjects. As a norm, reputation is seen as a path to ensure control of behaviors in order to align practices, discourses and attitudes to assure confidence and trust of shareholders, investors , stakeholders and society . The study demonstrated that is possible to design an integrating reputation management model supported by human variables and subjects integration, leading to the evolution of all subjects based on the values and standards instilled in each group and from which can generate confidence and may place the organization as a reference leader for new values and integrated normative standards

Abstract:

Mestrado em Marketing
As empresas competem umas com as outras por reputação.As empresas com boa reputação têm uma vantagem competitiva,aquelas que têm má reputação têm uma desvantagem competitiva (Fombrun,1990).Uma reputação favorável encoraja os shareholders a investir na empresa (Chun,2005),atrai bons colaboradores e retém clientes (Markham,1972) e está relacionada com retornos globais superiores (Robert&Dowling,1997;Vergin&Quoronfleh,1998).Uma boa reputação é um valioso activo para a empresa (Caruana,1997).Por ser um activo intangível,a reputação dificilmente é imitada pela concorrência. O consumo de suplementos alimentares entre os desportistas profissionais e recreativos é frequente e generalizado.A melhoria do desempenho desportivo é a principal razão do uso de produtos de nutrição desportiva,quer seja pela necessidade do consumo de nutrientes,acima da dose diária recomendada,como consequência do esforço intenso exigido pela prática desportiva,quer seja para compensar desequilíbrios na dieta diária. O objectivo geral deste estudo é medir a reputação da marca de nutrição desportiva EAFIT em dois grupos de stakeholders distintos?colaboradores e consumidores,comparando os resultados.Os objectivos específicos do estudo consistem na investigação da relação entre o constructo principal e os conceitos de satisfação e lealdade dos colaboradores e consumidores.O método usado é a Escala da Personalidade da Marca proposta por Davies et al.(2004).Foram desenvolvidos dois questionários -um destinado a consumidores e outro a colaboradores.Os resultados mostram semelhanças entre a identidade e a imagem da marca,e denotam a relação entre reputação e satisfação de consumidores e colaboradores.Pode concluir-se ainda que a lealdade dos consumidores não é independente do julgamento que fazem da relação qualidade/preço dos produtos EAFIT.Finalmente,colaboradores mais satisfeitos recomendam mais os produtos.
Companies compete for reputation. Organizations with good reputation have a competitive advantage, those that have a bad one have a competitive disadvantage (Fombrun,1990). A favourable reputation encourages shareholders to invest (Chun,2005), attracts good employees and retain consumers (Markham,1972), besides favouring superior financial performance (Robert&Dowling,1997,Vergin&Quoronfleh,1998). A good reputation is a valuable asset (Caruana,1997). Because reputation is an intangible asset, it is difficult to be copied by competitors. Dietary supplements consumption among professional and recreational athletes is widespread. Improving sports performance is the main reason of the use of these products, either by the need for nutrient intake, above the recommended daily dose, as a result of intense effort required by the sports modality, either to compensate daily diet mistakes. The main objective of this study is to measure reputation of the sport nutrition brand EAFIT among two groups of stakeholders - employees and customers, comparing results. Specific objectives are to discover the link between the main construct and satisfaction and loyalty of both employees and customers. The method used is the one proposed by Davies et al.(2004) - the Corporate Character Scale. Two surveys were developed - one for customers and another one for employees. Findings show similarities between identity and brand image. Results demonstrate that there is a positive correlation between reputation and customer and employee's satisfaction. Another conclusion is that customers that agree EAFIT products represent good value for money are more loyal. Finally, the more satisfied employees are, the more they recommend EAFIT products.

Abstract:

Les réseaux sociaux en ligne manifestent la transcription mais également l’intensification des rapports humains à l’échelle numérique. Plus généralement, l’apparition et l’usage massif de ces sites révèlent une évolution profonde des rapports sociaux commencée au milieu des années 2000. Partant, le droit pénal en tant que « miroir de la civilisation » s’en trouve nécessairement impacté au point de justifier une adaptation de ce dernier.Ces sites constituent indéniablement un nouvel espace juridique porteur de comportements cyberdélinquants. Pour la majorité d’entre eux, les réseaux sociaux en ligne ne sont qu’un nouveau support d’atteintes dont les incriminations préexistantes à leur apparition ont parfaitement vocation à s’appliquer. Cependant, de nouvelles formes d’atteintes ont émergé de ces espaces d’échanges mettant en lumière des carences structurelles au sein du droit pénal se traduisant par l’incapacité des incriminations préexistantes à appréhender ces nouvelles formes d’atteintes. Le droit pénal s’est alors adapté par la création de nouvelles incriminations témoignant de l’évolution profonde de la protection pénale de l’intimité et de l’identité mais plus généralement, de la vie privée.Les réseaux sociaux suscitent également des enjeux pour le droit pénal concernant la répression des comportements cyberdélinquants pouvant s’y retrouver. En l’occurrence, les régimes de responsabilité pénale applicables aux différents acteurs des réseaux sociaux, utilisateurs et opérateurs, démontrent une inadaptation certaine se matérialisant par un problème d’effectivité de la loi pénale sur les réseaux sociaux. La solution consiste alors à faire évoluer, ou plutôt diversifier la réponse aux infractions en développement et encadrant une régulation des contenus en collaboration avec l’autorité administrative. Se dessine ainsi un nouveau régime de responsabilité applicable aux principales plateformes numériques de partage favorisant progressivement en leur sein une logique de mise en conformité. Au final, le droit pénal s’adapte aux réseaux sociaux en ligne autant que les réseaux sociaux en ligne s’adaptent au droit pénal
Online social networks demonstrate the transcription, as well as the intensification, of human relationships on a digital level. More generally, the apparition and widespread use of these sites reveal a profound evolution of social relationships that began in the mid-2000s. Consequently, criminal law, as a “mirror of civilisation” has necessarily been impacted to the extent of warranting its adaptation.These websites undeniably constitute a new legal arena within which delinquent online behaviour is present. For the most part, online social networks are merely a new medium for infringements, to which pre-existing criminal offences are perfectly designed to apply, should they arise. However, new forms of infringements have emerged from these places of exchange, highlighting the structural shortcomings within criminal law, that manifest as the inability of pre-existing criminal offences to cover these new forms of infringements. Criminal law has therefore adapted through the creation of new criminal offences, demonstrating the profound evolution of the protection of privacy, identity and more generally, private life, under criminal law.Social networks also raise criminal law issues with regard to the suppression of delinquent online behaviour that can be found on them. In this case, the regimes of criminal responsibility applicable to different social network players, users and operators, demonstrate a certain unsuitability which manifests itself as the ineffectiveness of criminal law on social networks. The solution therefore consists of developing, or rather diversifying the response to emerging offences and providing a framework for the regulation of content in collaboration with the administrative authorities. A new regime of responsibility thus emerges, applicable to the main digital sharing platforms, that progressively promotes a principle of compliance within them. Ultimately, criminal law adapts to online social networks as much as social networks adapt to criminal law

Abstract:

Startups’ contributions on economic growth have been widely realized. However, the funding gap is often a problem limiting startups’ development. To some extent, VC can be a means to solve this problem. VC is one of the optimal financial intermediaries for startups. Two streams of VC studies are focused in this dissertation: the criteria used by venture capitalists to evaluate startups and the effect of VC on innovation. First, although many criteria have been analyzed, the empirical assessment of the effect of startup reputation on VC funding has not been investigated. However, reputation is usually positively related with firm performance, which may affect VC funding. By analyzing reputation from the generalized visibility dimension and the generalized favorability dimension using a sample of 200 startups founded from 1995 operating in the UK MNT sector, we show that both the two dimensions of reputation have positive influence on the likelihood of receiving VC funding. We also find that management team heterogeneity positively influence the likelihood of receiving VC funding. Second, studies investigating the effect of venture capital on innovation have frequently resorted to patent data. However, innovation is a process leading from invention to successful commercialization, and while patents capture the upstream side of innovative performance, they poorly describe its downstream one. By reflecting the introduction of new products or services trademarks can complete the picture, but empirical studies on trademarking in startups are rare. Analyzing a sample of 192 startups founded from 1996 operating in the UK MNT sector, we find that VC funding has positive effect on the propensity to register trademarks, as well as on the number and breadth of trademarks.

This thesis seeks to explain how moderators of satisfaction - reputation and involvement - act on the willingness to pay more and loyalty. These moderators were chosen because they are recognized in the literature as components which relates with cognitive and emotional elements that make up the satisfaction. The purpose of this study is to explain the influence of reputation and involvement variables on the relationship between satisfaction (independent), loyalty to the brand, and the willingness to pay more (dependent) for after-sales service. The gap that this study seeks to fill is to demonstrate to what extent consumer satisfaction with after-sales service contributes important aspects to the companies' market results. To this end, it aims to answer how the company's reputation and consumer involvement influence the effect of consumer satisfaction on loyalty and the desire to pay more. This quantitative study uses a survey to obtain data. After the collection, regressions were performed with the objective of verifying how the interaction between the variables occur. Of the 9 hypotheses constructed, 4 were confirmed, 2 were partially confirmed and 3 could not be verified. An unexpected result is that the response of the willingness to pay more as a function of satisfaction was linear, whereas the theory suggests that it should be non-linear. At the end, limitations, academic and managerial contributions as well as suggestions for future research are presented.
Esta dissertação busca explicar como dois fatores moderadores da satisfação do consumidor – reputação e envolvimento – agem sobre a disposição de pagar mais e a lealdade. Estas moderadoras foram escolhidas por serem reconhecidas na literatura como componentes que se relacionam com os elementos cognitivos e emocionais que compõem a satisfação. O objetivo deste estudo é explicar a influência das variáveis: reputação e envolvimento na relação entre satisfação (antecedente), lealdade em relação à marca e à disposição de pagar mais (consequentes) pelo serviço de pós-venda. A lacuna que este estudo busca preencher é demonstrar em que medida a satisfação do consumidor, com serviço de pós-venda, contribui com aspectos importantes para o resultado mercadológico das empresas. Para isso pretende responder como a reputação da empresa e o envolvimento do consumidor influenciam o efeito da satisfação desse sobre a lealdade e a disposição de pagar mais. Este é um estudo quantitativo que utiliza um survey para a obtenção de dados. Após a amostra coletada, regressões foram realizadas com o objetivo de verificar como a interação entre as variáveis ocorrem. Das 9 hipóteses construídas, 4 foram confirmadas, 2 foram parcialmente confirmadas e 3 não puderam ser confirmadas. Um resultado não esperado é que a resposta da disposição de pagar mais em função da satisfação se mostrou linear, enquanto a teoria aponta que deveria ser não linear. Ao final são apresentadas limitações, contribuições acadêmicas e gerenciais, bem como sugestões de pesquisas futuras.

Abstract:

A tarefa de avaliar a produção científica de um pesquisador é fortemente baseada na análise de seu currículo. É o que fazem, por exemplo, as agências de fomento à pesquisa e desenvolvimento ou comissões de avaliação, quando necessitam considerar a produção científica dos pesquisadores no processo de concessão de bolsas e auxílios, na seleção de consultores e membros de comitês, na aprovação de projetos ou simplesmente para avaliar o conceito de um programa de pós-graduação. Nesse contexto, a modelagem de perfis de pesquisadores é tarefa fundamental, especialmente quando se quer avaliar a reputação dos pesquisadores. Isto pode ocorrer por meio de um processo de análise da trajetória de toda a carreira científica do pesquisador. Tal processo envolve não somente aspectos relacionados a artigos ou livros publicados, mas também por outros elementos inerentes à atividade de um pesquisador, como orientações de trabalhos de mestrado e de doutorado; participação em defesas de mestrado e de doutorado; trabalhos apresentados em conferências; participação em projetos de pesquisa, inserção internacional, dentre outros. O objetivo deste trabalho é especificar um modelo de perfil de pesquisadores (Rep- Model) e uma métrica para medir reputação acadêmica (Rep-Index). O processo de modelagem do perfil envolve a definição de quais informações são relevantes para a especificação do perfil e as apresenta por meio de 18 elementos e 5 categorias. O processo para medir a reputação do pesquisador é definido por uma métrica que gera um índice. Esse índice é calculado mediante a utilização dos elementos constantes no perfil do pesquisador. Para avaliar a abordagem proposta na tese, diversos experimentos foram realizados. Os experimentos envolveram a avaliação dos elementos do Rep-Model por meio de análise de correlação e por algoritmos de mineração de dados. O Rep-Index também foi avaliado e correlacionado com duas métricas amplamente utilizadas na comunidade científica, o h-index e o g-index. Como baseline, foram utilizados todos os pesquisadores do CNPq das áreas de Ciência da Computação, Economia e Odontologia. O trabalho desenvolvido nesta tese está inserido no contexto da identificação da reputação de pesquisadores no âmbito acadêmico. A abordagem desta tese tem como premissa ser abrangente e adaptável, pois envolve a vida científica do pesquisador construída ao longo de sua carreira científica e pode ser utilizada em diferentes áreas e em diferentes contextos.
The task of evaluating the scientific production of a researcher is based strongly on the analysis of their curriculum. It's what makes the agencies for research support or evaluation committees, when they need to consider the scientific production of researchers in the process of awarding grants and aid in the selection of consultants and committee members in approving projects or simply to assess the concept of a program graduate. In that context, the modeling of profiles of researchers is fundamental task especially when one wants to evaluate the reputation of the researchers. This can occur by means of a process of analysis of the trajectory of all the scientific career of the researcher. Such process involves not only aspects related to papers or books, but also other elements inherent in the activity of a researcher, as orientations of master’s degree and doctorate; participation in defense of master's and doctoral degrees; papers presented in conferences, participation in research projects, international integration, among others. This proposal specifies a profile template for researchers (Rep-Model) and a metric to measure academic reputation (Rep-Index). The profile modeling process involves define which information is relevant to the specification of the profile and shows through 18 elements and 5 categories. The process for measuring researcher's reputation is defined by a metric that generates an index. This index is calculated by using the information contained in the profile of the researcher. To evaluate the approach proposed in the thesis, extensive experiments were conducted. The experiments involved the evaluation of Rep-Model by means of correlation analysis and data mining algorithms. The Rep-Index was also evaluated and correlated with two metrics widely used in the scientific community, the h-index and gindex. As a baseline, all of CNPq researchers in the areas of Computer Science, Economics and Dentistry were used. The work in this thesis is set in the context of identifying the reputation of researchers within the academic sphere. The approach of this thesis is premised be comprehensive and adaptable, because it involves the life science researcher built throughout his scientific career and can be used in different research areas and in different contexts.

This paper presents a new model of social-political perspectives impact on eWOM. eWOM can be regarded as a key indicator about personal reputation. In this study, we examined how eWOM is influenced by reputation and how political skills affect the reputation of social media. Therefore, a research model consisting of five hypotheses is proposed, including social astuteness, networking ability, apparent sincerity, interpersonal influence, reputation and eWOM. The experimental results show that social astuteness and networking ability are positively related to reputation. The relationship between reputation and eWOM is significantly positively influenced by interpersonal influence and apparent sincerity, which enhances the positive impact of reputation on eWOM when there is a high degree of political skill. Our findings suggest that the impact of political opinions on eWOM can be applied to social media. Keywords: Political skill, eWOM, Social astuteness, Networking ability, Apparent sincerity, Interpersonal influence, Reputation, Social media

Abstract:

The purpose of this study is to understand how a firm’s reputation for innovation influences the perceptions of co-created products. We investigated the impact of the co-creation claim (collaboration between customer and producer in the new product development process) against developed internally by firm professionals in the sportswear industry in terms of innovation ability, quality perceptions, attitude towards the product and willingness to pay. We investigated whether the level of firm’s reputation for innovation influences product assessments of co-created products. In order to do so we test two different new product development processes (by firm professionals and Cocreation) of a pair of running shoes in two firms with different levels of reputation for innovation. Results show that for companies with a high reputation for innovation the co-creation claim has a negative impact on product quality perceptions. Cocreation design mode did not affect significantly willingness to pay, overall product evaluations and innovation ability perceptions in these companies. Companies with low reputation for innovation are more likely to capitalize on co-creation initiatives. Our findings suggest that these companies benefit by informing consumers that a product was co-created, because it enhances substantially quality and firm ability perceptions. Furthermore consumers’ willingness to pay is higher for co-created products. Our findings indicate that, professionally developed products from companies with a high reputation for innovation have better perceive quality than professionally developed products from companies with a low reputation for innovation, suggesting that companies with high reputation for innovation are associated to higher manufacturing expertise.
O objetivo deste estudo é entender como a reputação por inovação de uma empresa influencia as percepções dos produtos co-criados. Investigou-se o impacto da co-criação (colaboração entre o consumidor e produtor no desenvolvimento de novos produtos) versus o método de desenvolvimento tradicional (com recurso apenas aos profissionais internos) na indústria de produtos desportivos em termos de: capacidade de inovação, percepções de qualidade, a atitude em relação ao produto e a disposição a pagar. Testámos dois processos diferentes de desenvolvimento de novos produtos (profissionais internos versus co-criação) de um par de ténis em duas empresas com diferentes níveis de reputação por inovação. Os resultados mostram que para empresas com uma reputação por inovação alta, a comunicação da co-criação tem um impacto negativo na percepção da qualidade do produto. A co-criação não afectou significativamente a disposição a pagar, avaliações de produtos e percepções de capacidade de inovação nestas empresas. Empresas com baixa reputação por inovação são mais propensas a beneficiar da comunicação da comunicação da co-criação. Os nossos resultados sugerem que estas empresas beneficiam, ao informar os consumidores de que um produto foi co-criado, dado que tal comunicação tem um efeito positivo nas percepções de qualidade do produto e capacidade de inovação da empresa. Além disso os consumidores mostraram-se dispostos a pagar mais por produtos co-criados versus produtos desenvolvidos internamente por profissionais. Os nossos resultados indicam também que, produtos desenvolvidos por profissionais de empresas com alta reputação por inovação beneficiam de melhores percepções a nível da qualidade do que produtos desenvolvidos por profissionais de empresas com baixa reputação por inovação, sugerindo que as empresas com alta reputação de inovação estão associadas a uma maior capacidade de desenvolvimento interno.

There are more and more people joining in e-auctions due to the mature of the internal auction websites. However, the situation of imposture cases on the websites are on the increase, the degree of trust between sellers and bidders is getting more important. Because sellers’ personal information isn’t offered on the websites, the seller reputation and historical bidding prices are the main information for bidders. Therefore, following such clues how do bidders judge whether sellers deserve to be trusted in? And how do they decide whether to bid or not? 　　This study adopts computer-simulated experiment (Experimental Design) to examine how buy price, current bid, and seller reputation affect trust and how seller reputation and trust affect bidding intention. The conclusions of the study are as followed. (1) A higher seller reputation will result in higher competence and integrity trust and it will also raise the bidding intention in the meanwhile. (2) Both of competence and integrity trust will raise the bidding intention. (3) Neither buy price nor current bid has any obvious influence on trust. 　　This study suggests e-auction operators should ban trustless sellers and offer complete reputation systems. It also suggests the sellers in e-auctions should know exactly the product what they offer and manage their reputations well.

Abstract:

O objectivo principal do presente estudo consiste em perceber de que forma se relacionam o intraempreendedorismo, a reputação e o empenhamento afectivo (EA). Foram recolhidas duas amostras (88 colaboradores e 93 clientes) numa empresa multinacional da área da restauração. A reputação pode ser definida, de forma lata, como um conjunto de crenças sobre a capacidade da empresa conseguir satisfazer os interesses dos vários grupos que se relacionam com ela (Gabbioneta, Ravasi & Mazzola, 2007). O intraempreendedorismo pode ser definido, por sua vez, como o empreendedorismo em organizações existentes (Antoncic & Hisrich, 2003). As relações entre intraempreendedorismo e reputação (e.g. Lumpkin & Dess, 1996), intraempreendedorismo e EA (e.g. Holt, Rutherford & Clohessy, 2007) e reputação e EA (e.g. Wiedmann & Buxel, 2005) têm sido sugeridas na literatura. Com o objectivo de testar as principais hipóteses foram utilizadas Correlações e a Regressão Linear. Verificou-se que o intraempreendedorismo tem um impacto positivo na reputação e no EA. Os resultados indicam ainda que a reputação tem um impacto positivo no EA e que possui um efeito mediador na relação entre intraempreendedorismo e EA. Adicionalmente, verificou-se que a reputação tem um impacto positivo na fidelidade de clientes. Os resultados sugerem, também, que não existem diferenças na percepção da reputação de acordo com a idade e o género, mas que existem differenças entre as percepções de grupos de interesse internos e externos à organização. São tecidas considerações relevantes para as temáticas em estudo e as implicações dos resultados são discutidas.
ABSTRACT: The main goal of the present investigation consists in understanding how intrapreneurship, reputation and affective commitment (AC) relate with each other. Two samples were collected (88 employees and 93 customers) from a multinational food service company. Reputation can be broadly defined as a set of collectively held beliefs about a company’s ability to satisfy the interests of its various stakeholders (Gabbioneta, Ravasi & Mazzola, 2007). On its turn, intrapreneurship can be defined as entrepreneurship in existing organizations (Antoncic & Hisrich, 2003). Relationships between intrapreneurship and reputation (e.g. Lumpkin & Dess, 1996), intrapreneurship and AC (e.g. Holt, Rutherford & Clohessy, 2007) and reputation and AC (e.g. Wiedmann & Buxel, 2005), have been suggested in literature. For testing the main hypothesis, Correlations and Linear Regression were used. The results show that intrapreneurship has a positive impact on reputation and on AC. The results also indicate that reputation has a positive impact on AC and that it has a mediating effect on the relationship between intrapreneurship and AC. Additionally, results suggest that reputation has a positive impact on customers loyalty. It was also verified that there are no differences on reputation’s perceptions according to age and gender, but that there are differences between internal and external stakeholders’ perceptions of reputation. Relevant considerations are made about the topics in study and implications of results are discussed.

Vivemos em tempos de mudança mediada por sistemas abertos e, isso não se aplica apenas à vida pessoal de cada um, como também, a outros setores dos quais as empresas são parte integrante. Ao longo dos anos, as empresas têm desenvolvido estratégias de captação e de fidelização procurando estar aonde estão os seus clientes (sejam eles efetivos ou potenciais). Os Social Media não escapam a este paradigma, o qual, apesar de tudo, é ainda novo e não totalmente compreendido. Embora, muitas empresas ainda lutem para perceber como se devem posicionar, a maioria não tem dúvidas de que mais do querer estar, têm que estar presentes nestes canais de comunicação. Assim sendo, as grandes questões que se colocam às organizações não é se devem ou não estar presentes, mas sim como estar e em que medida a sua presença pode trazer como benefícios melhorias ao nível da reputação organizacional e compromisso. Ciente que o tema dos Social Media, especialmente na vertente B2C, coloca diversos desafios, confrontos com várias questões, e no qual as empresas têm vindo a efetuar algumas apostas, o autor resolveu abraçar o desafio de refletir sobre a presença da TAP Portugal e EasyJet Portugal no Facebook, tendo como ponto de partida uma revisão de literatura fulcral na consolidação de conhecimentos fundamentais ao desenvolvimento da dissertação. Sendo a reputação e compromisso organizacional ativos intangíveis para as empresas, o autor propôs compreender a associação destes dois ativos e a familiarização dos clientes, de ambas as organizações, com as suas páginas no Facebook e respetivo impacto. A metodologia de investigação passa pela observação direta das páginas de Facebook das empresas referidas e aplicação de inquéritos aos usuários da página. Posteriormente, tendo por base uma análise crítica e comparativa de resultados, o autor espera inferir um conjunto de conclusões alusivas aos Social Media numa empresa premium e low cost, TAP e EasyJet, respetivamente.
We are living in times of great changes raised by open systems, and that does not apply to the personal life but also to other sector which the companies are part of. Over time, companies have been developing strategies to attract new customers and ensure the loyalty of the current ones by searching where the clients are (being them effective or potential ones). Social networks does not escape to this paradigm which, after all, is quite new and not totality understood. Although, many companies are still struggling to understand the best way to position themselves in the market, most of them do not have doubts that more than want, they have to be present in this media. Aware of this issue, especially in the B2C side, which disposes companies to new challenges, confronts to new questions, that have been allowed them to new approaches, the author decided to accept this challenge and study the impact of TAP Portugal and EasyJet Portugal´s presence on Facebook, having as starting point a literature review crucial in the consolidation of fundamental knowledge to the dissertation development. Therefore, as the corporate reputation and engagement have been accepted as valuable intangible assets for companies, the author decided to investigate the relation between these two assets and engaged consumers, against their Facebook pages and respective impact. The research methodology will include direct observation of their Facebook pages and an online survey to the users of their Facebook pages. Afterwards, according to a critic and comparative analysis the author aims to deduce some conclusions related to the Social Media use, of a premium and a low-cost company, TAP Portugal and EasyJet Portugal.

Recently, online auction has become a new type of e-commerce and also a popular topic for scholars doing researches. Online auction combines the conventional auction model with information technology. With both the convenience and connection provided by the Internet, it makes a different style and features for business transactions. However, in such a condition of information asymmetric within online auction, it also increases many risks and uncertain factors. According to previous studies, there are many factors of buying situation that will affect consumers’ online auction purchasing intention. Among these factors price and reputation have received significantly higher attention. However, the interactions effects between involvement and price and reputation on perceived risk, attitude towards websites and purchasing intention are rarely been discussed. In this study, we used experimental design to discuss whether the product price and e-retailer reputation will have influence on perceived risk, attitude towards websites and purchasing intention. The 2 (product price: high and low) × 2 (e-retailer reputation: high and low) model was conducted to analyze hypotheses and used involvement as a moderate variable. The results of this study indicated that product price and perceived risk negatively influenced purchasing intention. E-retailer reputation and attitude towards website positively influence purchasing intention. Besides, e-retailer reputation presented more influential effect than product price. Moreover, moderating effect of involvement on the influence of product price and e-retailer reputation on perceived risk and attitude towards websites indeed existed.

The purpose of this study is to understand how reputation for innovation influences the perceptions of co-created products. From a managerial standpoint this is an important topic given the growing importance of co-creation in the development of new products and because of the impact of corporate reputation on evaluation of co-created products. As such we investigated how consumers that do not participate in the co-creation process, i.e, the broader market, perceive the product outcomes of co-creation. Our setting is the insurance industry and we particularly look at the result of co-creation with customers and sale agents vis-à-vis developed by firm professionals. We focus on perceptions of firm innovation ability, intentions to recommend the firm, purchase intention and willingness to pay. Our finding show that firms that co-created are perceived with more innovation ability, display higher intentions to recommend and co-created products reveal higher purchase intentions. Interestingly, this highly innovative firms draw the least benefit from communicating co-creation. In these firms when the broad market learns that a product was cocreated innovation ability, intentions to recommend, purchase and willingness to pay decrease. As such the positive effect of communicating that consumers were involved in the development of the product is mainly benefitial for low innovative firms. In this instance, our finding indicate that co-creation enchances innovation ability as well as intentions to recommend and purchase. We then discuss implications for theory and practice.
O objectivo deste estudo é compreender como a reputação de inovação da empresa influencia as percepções de produtos cocriados, que da perspectiva da gestão, este tópico é crucial dada a crescente importância dos produtos co-criados e por causa do impacto que a reputação de uma empresa tem na avaliação dos produtos. Deste modo, investigámos como os consumidores que não participam no processo de co-criação, ou seja, o mercado percepciona os efeitos da co-criação nos produtos. O nosso estudo centrou-se na indútria seguradora e com especial atenção para os resultados da co-criação com clientes e mediadores em relação aos profissionais da empresa. Nós focámo-nos nas percepções dos clientes em termos de capacidade de inovação, intenções de recomendação, aquisição e disponibilidade de pagamento da empresa. A nossa descoberta mostra que empresas que co-criaram são percepcionadas com maior capacidade de inovação, demonstram maiores intenções de recomendação e os produtos co-criados revelam maior intenções de aquisição. Curiosamente, estas empresas inovadoras obtiveram o menor benefício de comunicar co-criação. Nestas empresas, quando o mercado descobre que o produto foi co-criado, a capacidade de inovação, intenções de recomendação e disponibilidade de pagamento diminuem. Assim sendo, o efeito positivo de comunicar aos consumidores envolvidos no desenvolvimento do produto é maioritariamente benéfico para empresas pouco inovadoras. Neste caso, a nossa descoberta indica que a co-criação melhora a capacidade de inovação, assim como intenções de recomendação e aquisição. Nós discutimos implicações teóricas e práticas destes resultados.

Eletronic commerce, know as e-commerce, is a system that consists in buying and selling produtcs/services over the internet. The internet is used by millions of people, making the management of the available information (e.g. competitor analysis market) a very difficult task for those operationg an e-commerce business. So that the managers can better position their companies against competitors, comes the need to create automatic mechanisms to extract information from various web sources (websites). The hotel business is a market where e-commerce is essential since the internet is their biggest selling point, either through sales channels or through their own websites. At the same time, these channels have important information, regarding the reputation of the hotel and their competitors, for instance in the form of guest comments. In this thesis a solution to some of those problems is presented, in which the main focus is the automatic extraction of information from sales channels, such as Booking. com. The extracted information is used to help the hoteliers in the analysis of the prices and opinions of hotel’s guests. That information will be extracted using web robots, able to analyze and interact with web pages, by simulating human behavior. This behavior simulation takes advantage of the navigation patterns present on most sales channels, so that users can easily follow the steps to the final purchase. Briefly describing the overall process, the web robot begins by filling the web site search form with a set of configurable parameters. For each hotel that met the search criteria the most relevant information is extracted, such as: prices, offers, comments and location of the hotel. The collected data is grouped and stored in an intermediate database. Once collected, the data is: (a) used by mathematical prediction models that analyze the prices of the hotels in recent years and generate a forecast of prices that hotels will practice in the future and, (b) used to check the hotel’s reputation taking into account the comments of the guests. This thesis presents a set of four papers resulting in past from the author’s work in project "SRM: Smart Revenue Management" financed by QREN I&DT, no. 38962, with promotor VISUALFORMA - Tecnologias de Informação, SA and co-promoter University of the Algarve.
A simplicidade do protocolo HTTP [19] e a extrema flexibilidade dos navegadores web (clientes HTTP) potenciaram o crescimento do número de sites e por sua vez o comércio eletrónico. O comércio eletrónico, também conhecido como e-commerce, é um sistema que consiste na compra e venda de produtos ou serviços através da internet [22]. Sendo a internet um meio de comunicação utilizado por milhões de pessoas, a gestão da informação que é disponibilizada e a análise do mercado concorrente torna-se uma tarefa bastante árdua para quem gere um negócio de e-commerce. Para que os gestores se possam posicionar melhor perante os concorrentes surge a necessidade de criar mecanismos automáticos capazes de extrair informação das várias fontes web (websites). A hotelaria é um mercado em que o e-commerce é imprescindível fazendo da internet o seu maior ponto de venda, seja através de canais de venda ou através dos seus próprios websites. Em simultâneo, os referidos canais apresentam informações importantes sobre a forma de comentários dos hóspedes, relativamente à reputação do hotel e seus concorrentes. Existem dois métodos principais para a procura de informação na web [93], sendo esses: (a) a extração manual através de cópia e colagem e a (b) extração automática através de web robots. Relativamente à extração manual, algumas empresas contratam pessoas para efetuar a extração manual dos dados. Este método consiste em procurar pela web e copiar/colar ficheiros, reformatar texto, imagens, documentos, ficheiros multimédia e outros dados. Este método de extração de dados torna-se dispendioso, pois exige bastante tempo e mão de obra. Por outro lado, para efetuar a extração de dados da web automaticamente, é necessário um crawler (web robot) para visitar as várias páginas web existentes, partindo de uma URL semente. À medida que estas URLs vão sendo visitadas pelo crawler, extraiem-se os dados da página HTML correspondente. Posteriormente por norma esses dados são armazenados numa base de dados, de forma a tornar o acesso aos dados mais eficiente. Nesta dissertação é apresentada uma solução para alguns problemas apresentados, em que o principal foco é a extração automática de informação de quatro canais de venda de reservas de alojamento, sendo esses Booking.com, Tripadvisor, Expedia e Bestday. A informação que se pretende extrair tem como função auxiliar os gestores hoteleiros a analisar a disponibilidade de quartos, os preços praticados e a opinião dos hóspedes relativamente aos hotéis concorrentes. Essa informação será extraída com recurso a web robots, capazes de analisar HTML e interagir com as páginas web simulando o comportamento humano. Esta simulação de comportamento tira partido dos canais de venda seguirem um padrão de navegação de modo a que o utilizador siga facilmente os passos até efetuar a compra. Por cada um dos canais de venda que se pretende extrair informação foi criado um web robot diferente, pois as páginas web estão estruturadas de maneira diferente. Descrevendo sucintamente o processo global, cada web robot começa por efetuar a pesquisa no formulário do respetivo website com um conjunto de parâmetros que são configuráveis. Após efetuar a pesquisa, são percorridos todos os hotéis que satisfizeram os critérios previamente definidos e de seguida é extraída a informação presente nos canais de venda, como sejam: os preços, as ofertas, os comentários e a localização do hotel. Esses dados são agrupados e armazenados numa base de dados não relacional. Nesta fase os dados armazenados estão em bruto, i.e., sem qualquer tratamento. Posteriormente, num processo independente (assíncrono), esses dados serão consolidados através de algumas regras previamente definidas de modo a eliminar redundância e a aumentar a consistência dos mesmos. Neste processo de consolidação existem várias preocupações, sendo possivelmente a principal a associação dos dados extraídos das diferentes páginas. Esta problemática surge devido à discrepância dos nomes dos hotéis nos diferentes canais de vendas. Além disso existem muitas outras discrepâncias entre os canais sendo as mais importantes: o número de estrelas das unidades hoteleiras, o nome dos quartos e a escala de pontuação dos hóspedes. Após concluído todo este processo de tratamento da informação, os dados são armazenados numa base de dados final. Ao contrário da base de dados usada na primeira fase, esta é uma base de dados relacional, o que significa que os dados estão devidamente estruturados possibilitando assim o uso por vários tipos de aplicações. Depois de recolhidos e consolidados, a finalidade dos dados é serem: (a) Utilizados por modelos de previsão matemáticos que analisam os preços praticados pelos hotéis nos últimos anos e geram uma previsão de preços que os hotéis irão praticar no futuro, e (b) utilizados para verificar a reputação dos hotéis tendo em conta os comentários dos hóspedes. Este trabalho não só apresenta a implementação dos web robots e da construção dos dados, como também uma vertente de análise da reputação dos hotéis através da análise dos comentários e pontuação dos hóspedes. A análise desses comentários e pontuações consiste em aplicar algumas regras de semântica e algumas métricas de modo a entender quais são os índices de satisfação dos hóspedes dos hotéis. Através destes indíces é possível verificar a importância de um hotel no mercado, pois num negócio são os clientes que definem o seu sucesso.
