With the explosion of technology we are finding that our methods of communication are  changing rapidly year to year. The way that we interact with each other from personal  levels to more formal business is all being affected. With the birth of the internet we have  seen continuous growth  of communication methods via this medium and most recently is  the boom of the Internet Based Networking Websites (IBNWs) that allow the, over  300million, users to interact with each other. Websites like Facebook, Linkedin, and  Twitter are very good examples of IBNWs that provide great platforms for communicating  messages and advertising companies regardless of where in the world they are. Geography  is quickly becoming an obstacle of the past as IBNWs allow business to reach people based  on their demographic rather then location. Through the use of IBNWs people can target,  segment, and filter according to the people they wish to advertise to, all for free. This in  turn is now having a huge impact on the advertising industry as ad agencies are being  pressured to change their more traditional marketing structures to fit the modern  environment, as people, especially young entrepreneurs, are finding a plethora of ways to  advertise online for free.    Because of this huge reshape of the advertising industry we have chosen to look in to how  this all affects the entrepreneur and therefore have taken on the task of answering the  question:    How do IBNWs affect the process of advertising in the development of new ventures?    In this thesis we delve in to the topic of modern advertising in relation to traditional forms  of advertising (T.V, Radio, Print) to see how and in what ways IBNWs are having an  impact of company start-ups. With the use of many authors and concepts we build a  theoretical perspective to help us analyze the data retrieved from 10 entrepreneurs from  around the world. The theoretical perspective is made of four key elements: Cost, Clutter,  Interactivity, and Objectives of advertising. With a qualitative interpretivist approach we  have constructed an in-depth case study that explores the development of 10 different  ventures from the perspective of the entrepreneurs running them. However to aid us in our  analysis and understanding of the industry of advertising and business development we  interviewed the Chief Creative officer at Ogilvy&Mathers, and an Manager at International  Venture Club.     The final goal of the study is to generate an original framework for entrepreneurs in modern  advertising. What we found was that due to the lack of resources by the entrepreneurs  IBNWs provide a great cost effective method of reaching a large and relevant audience.  Among other findings we found that IBNWs are a great starting point for all entrepreneurs  in their process of advertising due to its cheap and easy to use platform. In conclusion we  found that IBNWs do have a huge impact on the process of advertising in the development  of new ventures.     Keywords: IBNWs, Advertising, Cost, Clutter, Interactivity, Advertising Objectives

Objective: To determine which website characteristics are preferred by orthodontists, adult patients, and parents of patients. Materials and Methods: 1,000 active members of the American Association of Orthodontists and 750 active orthodontic patients/parents were sampled. Participants rated the importance of website characteristics, indicated presence of those characteristics on the current website, and ranked sample website images. Preferences were compared between orthodontist and the patient/parent group using t-tests and sample websites were compared using ANOVA models and Tukey’s adjusted post-hoc tests. Significance level was set at 0.05. Results: 11 of the 16 website features showed significant differences between patients/parents and orthodontists. Participants preferred sample websites with images of people, information at the top of the page, and an ‘about the doctor’ page with a greater amount of information. Conclusion: This study showed significant differences in preferences between orthodontists and patients/parents, by gender, and between adult patients and parents of adolescent patients.

Facebook’s status as the world’s largest social networking platform is well documented. However, studies focusing on Facebook are largely limited to how individuals and businesses use the platform and not on how Facebook expands globally and affects markets and competition in foreign countries. Although international communication scholars have scrutinized the international expansion of major media corporations like Time Warner, Disney and News Corp., analysis on Facebook remains scarce. This thesis seeks to fill in the gap in scholarly research by conducting a meso-level (i.e. organizational level) analysis of Facebook’s expansion into developing countries through the theoretical lens of networks. The network perspective was chosen because it has previously facilitated the most comprehensive analysis of the globalizing strategies of media corporations. This paper simultaneously serves as a test of the applicability of theories of networked globalization and the Network Society to the global expansion of ICTs, and in particular, social-networking websites.

Past research has shown that dialogic communication has essential characteristics that foster two-way communication between organizations and their stakeholders. This study investigates how public relations firms incorporate the principles of dialogic communication on their websites. The top and bottom 50 websites from the Holmes report on Top 250 Global PR agency rankings were content analyzed. Kent and Taylor’s (1998, 2003) five principles of dialogic communication were applied to find out if public relations firms incorporate the principle of dialogic communication effectively on their websites, provide relevant information for stakeholders and prospective clients, and if there are differences between PR rankings in terms of website usability and the dialogic loop. Findings reveal that bottom 50 PR websites are not as dialogic as the top 50 PR websites. In addition, the study revealed that both top and bottom to a considerable extent incorporated the principles of dialogic communication.

The rapid growth of the World Wide Web in the last decade makes it the largest publicly accessible data source in the world, which has become one of the most significant and influential information revolution of modern times. The influence of the Web has impacted almost every aspect of humans' life, activities and fields, causing paradigm shifts and transformational changes in business, governance, and education. Moreover, the rapid evolution of Web 2.0 and the Social Web in the past few years, such as social blogs and friendship networking sites, has dramatically transformed the Web from a raw environment for information consumption to a dynamic and rich platform for information production and sharing worldwide. However, this growth and transformation of the Web has resulted in an uncontrollable explosion and abundance of the textual contents, creating a serious challenge for any user to find and retrieve the relevant information that he truly seeks to find on the Web. The process of finding a relevant Web page in a website easily and efficiently has become very difficult to achieve. This has created many challenges for researchers to develop new mining techniques in order to improve the user experience on the Web, as well as for organizations to understand the true informational interests and needs of their customers in order to improve their targeted services accordingly by providing the products, services and information that truly match the requirements of every online customer. With these challenges in mind, Web mining aims to extract hidden patterns and discover useful knowledge from Web page contents, Web hyperlinks, and Web usage logs. Based on the primary kinds of Web data used in the mining process, Web mining tasks can be categorized into three main types: Web content mining, which extracts knowledge from Web page contents using text mining techniques, Web structure mining, which extracts patterns from the hyperlinks that represent the structure of the website, and Web usage mining, which mines user's Web navigational patterns from Web server logs that record the Web page access made by every user, representing the interactional activities between the users and the Web pages in a website. The main goal of this thesis is to contribute toward addressing the challenges that have been resulted from the information explosion and overload on the Web, by proposing and developing novel Web mining-based approaches. Toward achieving this goal, the thesis presents, analyzes, and evaluates three major contributions. First, the development of an integrated Web structure and usage mining approach that recommends a collection of hyperlinks for the surfers of a website to be placed at the homepage of that website. Second, the development of an integrated Web content and usage mining approach to improve the understanding of the user's Web behavior and discover the user group interests in a website. Third, the development of a supervised classification model based on recent Social Web concepts, such as Tag Clouds, in order to improve the retrieval of relevant articles and posts from Web social blogs.

The purpose of this study is showing that clear semantics and user-friendly navigability on IR websites are essential to communicate with single investors as well as their understanding of the Good Corporate Governance Practices adopted by firms that joined Bovespa s Novo Mercado. This work is divided into four stages. The first chapter explains what Corporate Governance is and how this concept was implemented in Brazil, introduces the stock market, Bovespa s Novo Mercado (New Market) and discusses subjects related to the financial sector. Next, it focuses on the evolution of corporate communications and how the organizations had to adapt their corporate culture and communications channels due to the ongoing and non-stop series of transactions (mergers & acquisitions and incorporations) that has been happening in Brazil since 1994, after Plano Real. This process enabled a geopolitical, cultural, economical and social alteration within corporations. Still in this chapter, the study shows the communications channels characteristics used by corporations in order to interact with their key public. Also, it displays how the internet and all digital media have integrated in this corporate process, the relationship with the investors, IR websites of the New Market firms and individual investor s profile. At last, the study shows the evaluation of IR websites, adopted criteria in order to examining homepage and further pages construction. At this point, the goal was to evaluate clear semantics, that is, the way the information is delivered to individual investors, the accessibility of this communication channel such as the number o clicks needed to obtain access to any piece of information and if the websites have specific areas for this public. Finally, the results are presented, as well as an analysis of corporate communication before and after joining Bovespa s New Market and the final conclusions.(AU)
O estudo pretende mostrar que a clareza semântica e a fácil navegabilidade nos sites de Relações com Investidores são essenciais para a comunicação com os investidores individuais bem como para a sua compreensão das Boas Práticas da Governança Corporativa adotadas pelas empresas que aderiram ao Novo Mercado da Bovespa. O trabalho está dividido em quatro etapas. O primeiro capítulo explica o que é Governança Corporativa, como esse conceito foi implementado no Brasil, apresenta o mercado de ações, o Novo Mercado e aborda os temas relacionados ao setor financeiro. Em seguida, aborda a evolução da comunicação empresarial e como as organizações tiveram que adaptar a sua cultura organizacional e os canais de comunicação devido à constante e ininterrupta série de transações (aquisições, fusões e incorporações) que acontecem no Brasil desde 1994, com o início do Plano Real. Esse processo proporcionou uma alteração geopolítica, cultural, econômica e social nas corporações. Ainda nesse capítulo o estudo apresenta as características dos canais que as organizações utilizam para se comunicar com os públicos de referência. Mostra também como a internet e as demais mídias digitais se integraram nesse processo corporativo, a relação com os investidores, os sites de RI das empresas do Novo Mercado e o perfil do investidor individual. Por último, o estudo apresenta a avaliação dos sites de RI, os critérios adotados para analisar a construção das homepages e demais páginas. Nesse ponto, o objetivo foi avaliar a clareza semântica, ou seja, a maneira como as informações são transmitidas para os investidores individuais, a acessibilidade desse canal de comunicação como a quantidade de cliques necessária para ter acesso a qualquer informação e se os sites possuem espaços específicos para esse público. Finalmente, são apresentados os resultados e uma análise da comunicação empresarial dessas empresas antes e depois da entrada das mesmas no Novo Mercado da Bovespa e as considerações finais.(AU)

La complexité de l'environnement dans lequel évoluent les organisations se traduit par la coexistence permanente d'interprétations multiples et contradictoires de la situation. Perturbées dans leurs capacités de décision et d'action, les organisations déploient des dispositifs sophistiqués de vigilance collective qui permettent de faire face à cette complexité, restaurant leur capacité à dégager du sens et à orienter leur action. La gestion de l'information en fait partie. Parmi toutes les sources disponibles, internet en général, et le web en particulier, constituent les principaux points d'accès à l’information, faisant désormais partie intégrante de ces processus de création de sens. L'évolution récente du paysage informationnel, tant du point de vue des outils que de celui des pratiques, suscite de nouveaux défis. Par leur facilité d’utilisation et leur accessibilité croissante, de nouveaux types de sources en ligne ont remis en question la façon dont les utilisateurs partagent, consomment et produisent du contenu. 

Cette thèse examine la remise en cause des processus habituels de vigilance collective, et en particulier celle de l'adaptation, chez les spécialistes de l'information, des stratégies d'évaluation de la qualité de l'information provenant des sources en ligne. La question de recherche mobilise trois éléments principaux :les professionnels de la gestion de l'information, l'évaluation de la qualité de l'information et l'évolution du paysage informationnel, qu'on appelle communément le Web 2.0. Pour répondre à cette question, une enquête de terrain a été menée auprès de 53 professionnels de la gestion de l'information en Belgique, entre novembre 2007 et juillet 2008. En l'absence de bases théoriques stables et largement acceptées, un cadre conceptuel spécifique a été développé pour assurer l'adéquation entre les éléments de la question de recherche et le dispositif. Ce cadre conceptuel a permis de faire la lumière sur ces éléments. Le recours à une approche sociopsychologique a permis de les articuler, notamment par emprunt aux travaux de Karl Weick et au concept de sensemaking. 

La gestion de l'information (GI), considérée comme un processus de vigilance collective, est un concept générique, comprenant les activités de surveillance, de veille ou encore d'intelligence (économique, stratégique, compétitive, etc.).

Sa conceptualisation, construite par une analyse de définitions des principaux termes qui lui sont associés, a mis en évidence l'importance de son rôle de médiateur d'information dans l'organisation, qui s'articule autour des étapes récurrentes de collecte, de traitement et de distribution de l'information. Le recours au concept d'organizational learning a permis de dépasser les approches purement mécaniques, mettant en évidence sa capacité à créer du de sens. 

C'est au coeur de cette médiation, à l'intersection de la collecte et du traitement de l'information, qu'intervient un autre type de sensemaking: l'évaluation de la qualité de l'information. Elle est envisagée comme un processus de réduction de l'ambiguïté, dont l'action permet la sélection (ou non) d'une source ou d'une information dans la suite de la médiation. La qualité de l'information est abordée sous l'angle de l'information seeking qui permet de faire la lumière sur cette création de sens. Elle est généralement traitée dans la littérature en termes de pertinence, de crédibilité ou de fitness for use. Des études de terrain et des contributions émanant des praticiens ont permis de mettre en évidence les attributs et les critères de la qualité qui peuvent être mobilisés pour construire un jugement de qualité des sources en ligne. Dans le cadre de l'enquête de terrain, une check-list composée de 72 critères renvoyant à 9 attributs a été choisie comme cadre de référence pour l'observer: les objectifs de la source, sa couverture, son autorité et sa réputation, sa précision, sa mise à jour, son accessibilité, sa présentation, sa facilité d'utilisation et sa comparaison avec d'autres sources. 

 

Pour pouvoir mettre en évidence de manière concrète les aspects du paysage informationnel en transformation, une analyse des définitions et descriptions du Web 2.0 a permis de construire une description morphologique qui reprend ses caractéristiques principales. Il peut ainsi être considéré comme un ensemble d'outils, de pratiques et de tendances. Les outils permettent d'identifier cinq types de sources qui lui sont spécifiques: les blogs, les wikis, les podcasts, les plates-formes de partage de fichiers et les sites de réseaux sociaux. Ces types de sources sont éclairés dans cette recherche sous l'angle du concept de genre et, ensemble, sont positionnés en tant que répertoire, qu'il est nécessaire de comparer avec celui des genres "classiques" de sources en ligne. 

L'examen du changement des stratégies d'évaluation de la qualité de l'information a été concrétisé à l'aide d'un questionnaire administré par téléphone, qui visait à croiser les critères de qualité de la liste choisie comme référence avec les cinq genres typiques du Web 2.0. C'est l'importance relative accordée à un critère pour évaluer une information qui a été choisie comme indicateur à observer. Les répondants ont été invités à indiquer s'ils considèrent que l'importance des critères "change" ("≠") ou "ne change pas" ("=") quand ils évaluent un de ces genres, en comparaison de celle qu'ils accorderaient à un genre classique de source en ligne. En cas de changement, le questionnaire a prévu la possibilité de noter s'il s'agissait d'une hausse (">") ou d'une baisse ("<") d'importance. Pour compléter ce dispositif, 14 entretiens semi-dirigés en face à face ont été menés avec des répondants à ce questionnaire, de manière à pouvoir saisir les éléments explicatifs de leurs réponses. 

L'analyse des données a montré qu'une majorité des réponses (57% de "=") indiquent que l'importance des critères d'évaluation ne change pas quand une information est mise à disposition par l'intermédiaire d'un genre Web 2.0, plutôt que par celui d'un genre classique de source en ligne. Pourtant, cela implique que 43% des critères changent d'une manière ou d'une autre. C'est sur base de ce constat que cette recherche soutient l'existence d'un changement perçu qui, s'il ne remet pas fondamentalement en cause le processus de jugement de qualité, suscite néanmoins une adaptation de ce dernier par les professionnels de la GI interrogés. La lecture des données à l'aide de variables secondaires a montré notamment une forte disparité des distributions de réponses entre les répondants; ce qui plaide en faveur du caractère subjectif, personnel et dépendant du contexte du processus d'évaluation. De même, elle a permis de déterminer l'existence de deux groupes d'attributs qui se différencient par le fait que le premier comporte des attributs liés au contenu de la source (les objectifs, l'autorité, la précision, etc.) alors que le second est composé d'attributs liés à la forme (présentation, facilité, etc.).

Les entretiens de la seconde phase de l'enquête ont permis d'affiner l'analyse en éclairant, d'une part, sur la nature du changement et, d'autre part, sur les raisons de celui-ci. Les répondants ont indiqué que fondamentalement le processus d'évaluation est identique quel que soit le répertoire envisagé. Ils admettent toutefois que les genres typiques du Web 2.0 peuvent être à l'origine d'une perte de repères. Elle s'explique par la perception d'une familiarité moins grande à l'égard des sources et se traduit par une perte de la confiance qu'ils accordent aux sources et à leur jugement. Le changement perçu se manifeste donc par une hausse d'importance de certains attributs, qui aide les répondants à restaurer cette confiance. L'élément explicatif de ce changement peut être considéré comme un flou dans les modalités de création de contenu. Ce flou comporte trois dimensions: la façon dont est créé le contenu (How?), l'identité de celui qui le crée (Who?) et sa nature (What?). Ces dimensions peuvent être synthétisées par l'idée selon laquelle n'importe qui peut publier n'importe quoi. 

Les entretiens approfondis confirment que les groupes d'attributs liés au contenu d'une part, et ceux liés à la forme d'autre part, sont bien des éléments explicatifs de la manière dont se manifeste le changement.  Dans le cas des attributs qui augmentent d'importance, les raisons invoquées renvoient au fait que la facilité de création de contenu à l'aide de ces genres permet à "n'importe qui" de créer du contenu. C'est pour cette raison que l'autorité et les objectifs de la source peuvent faire l'objet d'une attention plus forte que sur les genres classiques de sources en ligne. Le fait que n'importe qui puisse publier "n'importe quoi" renvoie à la nature du contenu créé par ces genres. Il est considéré comme dynamique, personnel, indicateur de tendances, source de signaux faibles, subjectifs, etc. Cela pousse les répondants qui sont sensibles à ces questions à remettre plus sérieusement en cause la précision par exemple. C'est aussi en raison de la facilité de création de contenu, et du fait que les outils du Web 2.0 réduisent la responsabilité de l'auteur dans la qualité de la conception de sa source, que des attributs de forme, quand ils changent d'importance, voient leur niveau baisser. Le second groupe a été signalé par les répondants comme étant davantage des indicateurs de sérieux et des arbitres dans leur processus d'évaluation.

Que ce soit pour discuter des divergences de vue entre répondants ou pour déterminer les spécificités des genres, il apparaît qu'un aspect capital de la qualité de l'information tient à sa capacité à répondre aux besoins du moment, le fitness for use. Cette notion est intimement liée à celle de pertinence et toutes deux ont été résolument présentées comme déterminantes dans les stratégies, à la fois du point de vue du jugement d'une information ponctuelle, que dans l'attitude face à aux sources en général. Dans tous les cas, c'est d'abord les besoins d'information qui guident le choix. Toutes observations permettent d'apporter une réponse claire, riche et nuancée à la question de recherche.

The rise of the Internet has made traditional newspapers adjust their business models toward digital to diversify their revenue sources. Online news websites, thus, are growing popular in Taiwan. This study aimed to understand the competitive advantage of the online-only news website through Porter’s value chain analysis. It also adopted the concepts of virtual value chain, online news value chain, and knowledge value chain into one analytical framework to examine the major activities and supporting activities of the online-only news websites. Furthermore, this study compared commercial and social enterprises to point out the possibility of an innovative business model for the online-only news website. In-depth interview and document analysis were used to examine the commercial and social enterprise. In this study, NOWnews, one of the earliest online-only news websites in Taiwan, is a representative for the commercial enterprise group, whereas, Newstalk, the first social enterprise of news, for the social enterprise group. Results show that the commercial enterprise regarded high website traffic as the most important company obejctive to attract advertisers. Besides, the commercial enterprise created its competitive advantage through diversification of businesses and innovation of new media technologies. However, the social enterprise took advantage of free resources and social networking sites to break through the limitation of market economy. The social enterprise also adopted the idea of cause-related marketing as their competitive strategy to engage their supporters.

Contemporary feminism is playing out in increasingly digitised ways as women utilise the Internet and social media to discuss, disseminate and debate key feminist ideas in women-centred dedicated spaces. The speed and scope of digital communications technologies has allowed for the mobilisation of individuals around issues of gender inequality on a global scale while simultaneously launching feminism into the cultural zeitgeist. The rapid pace of technological advancement, the seemingly endless integration of the Internet into our everyday lives, and the corporate colonisation of the digital sphere are all changing the ways in which people understand and interact with feminist thought. As such, the impact of the digital environment on the aims and ideologies of contemporary ‘networked’ feminist communities, and the politics of participation in networked social movements in general, require close scholarly interrogation. Using a case study approach, this research draws from the theoretical toolkit of Pierre Bourdieu in order to analyse the shape and nature of the largest networked feminist community on the social news website Reddit: r/TwoXChromosomes. Comment data collected directly from the 15 popular threads selected for analysis was enriched by moderation and administration guidelines framing the community and Reddit more broadly, providing a rich and multifaceted dataset on which a reflexive thematic content analysis was conducted. This study aims to contribute to understanding the challenges and advantages women face as they organise around feminist issues in the online spaces that are governed primarily by the motivation to accumulate profit. It reveals a number of critical tensions at the foundation of r/TwoXChromosomes as a contemporary networked feminist community.

This dissertation explores deviance, operationalized through news factors, among American community weekly, community daily, large daily, and national daily newspaper websites and social media posts. Computerized quantitative analysis indicates that circulation size makes little to no significant difference concerning the publication of deviant news factors; smaller circulation sizes are significantly related to the publication of news concerning local communities, but not egalitarian news factors generally. Qualitative, structured interviews of community newspaper editors and publishers illustrate a different agenda - a clear focus for news on "regular people and routine events," arguably egalitarianism, over news on "unusual people or extraordinary events," arguably deviance. This indicates a need for further evaluation and development of computerized content analysis, gatekeeping theory, and the community newspaper industry. Results also suggest a need to reconsider and re-evaluate normative deviance as a concept and point to two potential theoretical developments: considering a Deviant-Egalitarian Spectrum and drastically broadening the current fringe focus of deviance research.

With the development of the Internet era, e-commerce has grown rapidly. Many people choose to buy goods on the Internet. It is not only convenient but also fast. As long as customers can access the Internet, they can purchase goods through the online store no matter where they are. In recent years, the number of people using shopping websites to purchase goods has increased year by year, and online news and comments have greatly influenced consumers' decision to buy products. In such a highly competitive environment, a shopping website can use online news to analyze their strengths and weaknesses, and formulate relevant strategies to enhance competitive advantage. This study takes three famous shopping websites in Taiwan, including PChome, Yahoo Shopping, and Momo shopping, as examples to analyze related online news by text mining techniques and social network graphs. Frequent terms of online news for each shopping site and relationships among three shopping sites are analyzed and compared. Then, the Genetic algorithm is employed to calculate the coordinate of each frequent term, and the concept of social network graph is used to display those relationships graphically. Sentimental analysis is adopted to analyze the positive and negative tendencies of each term. In addition, this study uses machine learning methods, including decision tree, support vector machine and neural network, to analyze the impact of the content of on-line news on the stock price, which can be provided to investors for reference. The analysis results can help the managers of the shopping website understand the impressions and opinions of the website from customers’ viewpoints, and help them to adjust their business strategies and enhance their competitiveness.

Through the rapid development of internet, the social networking service (SNS) serves a novel online socializing channel for users. Based on this kind of service, the virtual socializing style has already became indispensable part for our life. This study is intended to investigate the interface usability of social networking website. The research results can be used in promoting the practicability of current social networking websites and in developing new user interface with more intuitive usage. The experiment in this study includes two stages: (1) The pilot test: The purpose is to investigate the current social networking interfaces. In this stage, the author will obtain the usability of each user interface including the operating style, usability, user satisfaction regarding their experiences and the way of interaction on each experimental sample. (2) The validate experiment: Based on the results generated from the first stage, the independent variables are identified. The research will aim at the news feed interface on social networking websites. The validate experiment was planned based on a 3 (levels of information representations) by 3 (layout styles) two-way ANOVA design. There are three levels in the independent variable of information representation: (1) Information is represented as a whole: The information (text content) of news feed interface was represented. (2) Information is represented the same as the current interface: The information (text content) of news feed interface was represented same as current interface. Besides, the text beyond 5 lines will be hidden beneath the button. (3) Information is represented as a brief: The information (text content) of news feed interface was represented as a brief. Besides, the text beyond 1 line will be hidden beneath the button. There are two levels in the independent variable of layout styles: (1) The current layout style: The width of layout of news feed interface is same as the current interface. (2) The wide layout style: The width of layout of news feed interface is about 35-38 characters width and wider than the current layout style. The generate results indicated that: (1) The result of testing on the user who has the experience on using social networking websites but was arranged on the testing website at the first time felt that the most attracting part of social networking interface is its own abundant functions. But at the same time, the user interface may lower the usability and satisfaction of experience quality if it is represented with too much information by list. (2) The results of task performance are that in some tasks the independent variables of information representation and layout style are significance. The analysis showed that, the information represented as current interface is better than others and the wide layout style is better than current layout style. The interaction has significant difference between “information representation” and “layout style”. (3) The results of system usability are information representation as a brief better than represented as a whole and current user interface. From users’ viewpoints, the value of usability will increase if information is represented as a brief in this news feed interface that is full of mass information. (4) The interaction in system usability is significance. With regard to the information represented as a whole is much more suitable for current layout style, but not the information represented as a brief. On the contrary, the information represented as a brief is suitable for wide layout style. And this interface design is better than others. (5) QUIS data analysis showed, generally, the interaction is not significant. But the QUIS in immersion dimension and scenario dimension are significant and wide layout style is better than current layout style. The QUIS values in most of the experimental samples are more than 4. Keywords: Social networking website, Information representation, Layout style, News feed interface, Experience design

The development of Internet technology, the emergence of social networking sites has changed the way of communication between people, through the Internet, people's relationship to a closer, more and more users choose a Social Website Platform to share with friends and build relationships, making the inextricable relationship between the people and the Social Website Platform. Social networking sites also changes along with time. The trend to set the personal data to transparency, openness, therefore brings a lot of privacy issues, such as the leakage of personal information. Social networking websites in order to balance openness and privacy issues updates privacy settings, and policy, many times to reduce privacy issues as well. On October 1, 2012 implementation of the New Personal Data Protection Act is more rigorous to protect of users' personal data. After the implementation of the Act, users make use of social networking sites, we want to know whether they one more concerned about the protection of personal data, the change of the users behavior. The case of Facebook, to explore after the implementation of the New Personal Data Protection Act, whether the intention of the behavior using the social networking sites is influenced by perceived privacy risk, privacy mechanism and privacy information concerns. The study surveyed 426 valid samples. According to the results of statistic analyze: information privacy concerns significantly affect attitudes. Perceived privacy risks affect attitude as expected. Structural guarantee and privacy empowerment significantly affect trust. Trust, subjective norms and attitude significantly affect behavioral intentions.

Under the development of communication technology, More and more people began to pay their attention to national defense affairs by using social media. The rise of Facebook not only changed the personal life, but also affected the media environment and became the policy advocacy and supporting competitions of national defense departments. the new media platform, since 2007, supported by the United Kingdom, the United States and many other countries have gradually established a military-specific fan page. Our Ministry of National Defense has also set up a Facebook fan page on May 24, 2011, which is a bilateral way of communication between the military and the civilians. On February 20， 2014, the Navy Command Headquarters of NMD established a Facebook fan page, and so far the number of followers has reached more than 70,000. While the interactions between the military and civilians of each article has not exceeded 10,000 people. Therefore, this study attempts to understand the current website management strategy by analyzing the posting of the Republic of China Navy's Facebook. This study uses the content analysis method to publish 180 articles of the Republic of China Navy Facebook fan page from July 1st to November 30th, 107, and distributes five categories: document strategy, document content, document nature, communication direction and release time. Analyze and find out by data such as the number of praises, the number of comments, and the number of shares in each article: 1. Among all the published content, the "sweepstakes" is the most effective way to attract the readers, which has a significant impact on the number of votes, messages and the shares. 2. The most effective way to attract readers to interact with each other and thumb up is "video". 3. If the communication direction is "bilateral Reader’s", the reader's willingness to interact will be enhanced. 4. "Publishing time" does not affect the readers’ willing of interaction of the Republic of China Navy's Facebook fan page to listen to people's interactions.

Africa’s way forward requires integration, democracy, good governance, participation and inclusive communication of all issues. Intergovernmental organizations are essential to facilitate the above mentioned goals. New thinking highlights the role of new media especially the Internet in democracy and governance in Africa. Therefore, the question solicited here is whether e-governance facilitates continental governance in Africa and under what circumstances would this be possible? This research introduced the internet (web) as a distinct medium of communications with distinct features and characteristics. A number of scholars argue that the Internet as a distinct medium of communication can better facilitate the democratizing role of the media in society, while others argues that the internet has not changed the nature of politics since ordinary politics in all its complexity and vitality has invaded and captured cyberspace. These arguments are divided respectively between Technological Determinism and the Social Shaping of Technology. This research investigates (AU, EU and Nepad) e-governance websites in order to understand practices, prospects and challenges of continental e-governance systems. It was found that the AU and Nepad use the websites for institutional information rather than interaction with citizens and online service delivery. However, significant steps are taken to enhance interaction in Nepad. It is therefore recommended that, the AU and Nepad need to invest time and commitment in enhancing interactivity and rising awareness for these e-governance systems. As projected, EU performs much better than the above two in terms of interactivity. This is because it has more experience and internet penetration and uses is widespread in Europe than it is here in Africa.

Intitulada ‘Os critérios de noticiabilidade das notícias acerca da União Europeia’, esta dissertação pretende perceber quais são os valores-notícias presentes nos outputs dos meios de comunicação que utilizam imagens audiovisuais provenientes do website do Parlamento Europeu (PE). O conceito central para a contextualização deste estudo baseia-se nos ‘valores-notícia’, com o objetivo de perceber como estes critérios ajudam a construir uma determinada representação nos cidadãos da União Europeia, o que, indiretamente influencia a identidade europeia.

Concluímos neste trabalho que existe uma preocupação pelo Parlamento Europeu em ser mais transparentes e aproximar-se dos seus cidadãos. Com a análise do website Multimedia Centre, para além de verificarmos uma preocupação crescente desta instituição parlamentar em tentar melhorar a sua relação com os media, é visível uma proximidade dos meios de comunicação à agenda do PE.

This paper analyzes whether a company’s image affects its capability of attracting young employees. To do so, the process that leads to the creation of a company’s image by young professionals and the relevance they attribute to companies’ websites were addressed. By using the websites of 20 companies and conducting 12 semi structured interviews near recent graduates, it was possible to conclude that companies and young professionals seek different sources when it comes to form an image of a company and hence, what is perceived by companies as relevant to be communicated, is disregarded by young professionals given its indistinctiveness.
