Abstract:

Includes bibliographical references (leaves 81-90).
Before organisations adopt agile methods, they need to ensure that they are prepared for the change. They also need to understand the problems they are trying to address by adopting agile methods. Agile methods deviate substantially from traditional methods of systems development (Tolfo & Wazlawick, 2008). This, therefore, makes it difficult for organisations to adopt agile methods even though they might see them attractive, as the adoption of such methods has an effect on organisational culture. If the culture cannot accommodate an agile approach, then the organisation will not be able to adopt agile (Lindvall, Basisli, Boehm, Costa, Dangle, Shull, Teseriero, Williams & Zelkowitz, 2002). Having a culture that is conducive to the adoption of agile methods is almost unanimously perceived by agile experts to be a necessary factor for the introduction of agile methodologies (eWorkshop, 2002). It is also important to understand the phases organisations go through during the process of adopting agile methods.

Abstract:

This thesis has created an image of the exchange of information among teachers in the Swedish upper secondary school. The study indicates that the exchange of information seems to be limited at all levels and the exchange that takes place outside the own teaching team occurs mainly through teachers personal networks. The study also shows barriers that may exist and the opportunities that an increased exchange may generate. From the picture that the empirical material provides and the theory that is presented a discussion is made around how IT can best support the organizational learning in schools. A concrete proposal is that at national level an IT platform should be created, which primarily focuses on materials that are created by its users and has an open architecture with a single login.

Abstract:

Swedish health care is far behind society in general when it comes to using digital tools. One example of this is The Department for investigation of infectious diseases in Västerbotten, where work is still documented on paper or in Excel and stored in physical binders. As an attempt to start a first introductory conversation in order for Health Care to have an intuitive and aesthetically pleasing digital system that is more in phase with the present, this study aims to answer the question How could a digital infection tracking system be visualized to support Health Care in Västerbotten? This was investigated through an initial qualitative interview with two hygiene doctors and three hygiene nurses. The data was analyzed and resulted in four criteria to meet their needs and expectations. An exploratory design phase followed which led to the design of a clickable prototype. The prototype was tested under observation with four hygiene doctors and four hygiene nurses. The data from the observation was analyzed against the same four criteria, which showed that the criteria were met in some parts but also that a good user-friendly design needs more iterative laps. It also indicated the importance of information vitalization as a support to make work more efficient.

Abstract:

The purpose of this study was to describe senior nurses’ expectations concerning how a digital information and communication technology systems (ICT) can contribute to the improvement of care leadership and how it can strengthen ties between the school's theoretical world and the practical clinical work-based training (WP) in nursing. The study has a descriptive design with a qualitative approach. The study involved seven leading care nurses. Data were collected through semi-structured interviews. Subject matter was analyzed based on qualitative content analysis. The analysis yielded in a first category practical examples of how using ICT as a tool could strengthen the ties between theory and practice in order to understand the usefulness of theory in practice. The informants also gave specific examples of ICT content that could be given to students and also to supervisors both in terms of information and education. The second category described the supervisors’ views on receiving students in clinical placements. The senior care nurses felt that at present the reception of students was unsatisfactory due to a muddled organization. It was often unclear what responsibilities they had as mentors and what the responsibility of the student was for his or her practice placement. Conclusions of the study are that the supervisors could see ICT as a tool to clarify these ambiguities. In the future it is necessary to respond to the needs of supervisors with respect to their views on what an ICT system should provide them with in order to improve their care supervision. By providing an ICT learning tool the two worlds could meet and the ties between theory and practice in the nursing program could be strengthened.

Abstract:

I dagens ständigt föränderliga affärsvärld finns en mängd olika information tillgänglig för organisationer och med utvecklande teknologier finns möjligheten att tillvara ta på denna information till att bättre kunna förstå sin verksamhet och därtill utveckla den. Syftet med denna kandidatuppstas är att undersöka och identifiera vilken påverkan som informations möjliggörande business intelligence applikationer kan ha för att möjliggöra och stödja verksamhetsutveckling. Undersökningen är gjord utefter en kvalitativ forskningsmetodik med kvalitativa intervjuer som datainsamlingsmetod där fyra intervjuer är genomförda för fyra olika typer av organisationer där respektive intervjuperson arbetar med business intelligence på något sätt regelbundet. Intervjuerna var semi-strukturerade där frågorna togs fram utefter studiens teoretiska referensram, som sedan analyserades utefter en tematisk analys. Resultaten för studien visar på att business intelligence är en möjliggörare för att kunna skapa diverse olika nyttor inom olika verksamheter med ett påtagligt värde. Slutsatserna för studien påvisar också att det är svårt att kunna härleda särskilda verksamhetsutvecklings möjligheter för enskilda informationsapplikationer inom BI-lösningar. Men att BI som en helhetslösning är ett underlag för verksamhetsutveckling och utveckling för affärsmöjligheter, processer och prestanda är något som påvisas efter genomförd studie.

Abstract:

Feedback kan definieras som en process där effekten av en handling returneras till sin källa för att förändra framtida handlingar. I undervisningssystem är feedback oftast förknippat med lärarens respons på studentens prestationer. Tidigare forskning visar att feedback-processen mellan lärare och student är komplex och involverar en rad problemområden. Denna studie syftade dels till att undersöka, ur studentens perspektiv, om dessa problemområden förekommer vid Linnéuniversitetet och dels till att beskriva och analysera de problemområden som bekräftas existera, med stöd av informations- och kommunikationsteorier. De teorier som har använts i denna studie är Shannon-Weavers och Schramms kommunikationsmodeller, kriterier för informationskvalitet och Media Richness Theory. I studien användes en kvantitativ metod med en deduktiv ansats, som genomfördes med hjälp av en enkätundersökning riktad till studenter vid Linnéuniversitetet. Resultat/analys identifierade problemområden och beskrev dessa genom valda teorier. Slutsatsen besvarade frågeställningarna om vilka problemområden som identifierades vid Linnéuniversitet, samt hur dessa problem kan beskrivas med hjälp av studiens valda information- och kommunikationsteorier.
Feedback can be defined as a process where the effect of an action is returned to its source in order to alter future actions. Within educational systems feedback is commonly associated with the teacher’s response to student performance. Previous research shows that the feedback process between tutor and student is a complex one that involves several problem areas. This study aimed to explore, from a student perspective, whether these problem areas exist at Linnaeus University and to describe and analyze existent problem areas with information- and communication theories. The theories used in this study are Shannon-Weavers models of communication, criteria for information quality and Media Richness Theory. The study has been conducted with a quantitative method and a deductive approach, carried out by a survey targeted to students at Linnaeus University. The result/analysis of the study identified problem areas and described them with the selected theories. The conclusion of the study was an answer to the question regarding which problem areas can be identified at Linnaeus University as well as how these problems can be described with the use of the study’s selected information- and communication theories.

The paper emphasises the importance of a research programme focused on developing and making widely available GIS relevant spatial analysis technology. It outlines generic criteria able to discriminate between GIS-relevant and GIS-irrelevant spatial analysis tools and outlines a list of six researchable spatial analysis themes. It is argued that presently there is an opportunity to develop a EU based spatial analysis research programme and then install the technology in the World's GIS. (authors' abstract)

Abstract:

The conditions for the third, non-profit sector, such as grassroots organisations and trade unions, have changed dramatically in recent years, due to prevailing social trends. Non-profit organisations have been seen as early adopters of information technology, but the area is, at the same time, largely unattended by scientific research. Meanwhile, the field of information systems development is, to an increasing extent, recognising the importance of user involvement in the design process. Nevertheless, participatory development approaches, such as Participatory Design are not suited to the context of entire organisations, and new, networked organisational structures, such as those of non-profit organisations. This reasoning also applies to the theoretical framework of Activity Theory, whose potential benefits for systems development have been acclaimed but less often tried in practice. This thesis aims, first, at extending Participatory Design to use in large, particularly non-profit organisations. This aim is partly achieved by integrating Participatory Design with an Argumentative Design approach and with the application of Activity Theory modified for an organisational context. The purpose is to obtain reasoning about and foreseeing the consequences of different design solutions. Second, the thesis aims at exploring information technology needs, solutions, and consequences in non-profit organisations, in trade unions in particular. The case under study is the Swedish Trade Union Confederation (LO) and the design of an information system for its 250 000 shop stewards. The thesis is based on six related studies complemented with data from work in a local design group working according to the principles of Participatory Design. The first study was aimed at investigating and comparing trade union management’s view of the new technology and the actual needs of shop stewards. The second study investigated the situation, tasks and problems of shop stewards, as a pre-requisite for finding information technology needs. The third study merged the previous findings into an argumentative design of an information systems design proposal. The fourth study collected the voices from secondary user groups in the organisation, and presented an Activity theoretical analysis of the union organisation and a modified design proposal in the form of a prototype. The fifth study presented an Activity theoretical framework, modified for organisational application, and used it for producing hypotheses on possible shop steward tasks and organisational consequences of the implementation of the information system. The sixth paper was aimed at the initial testing of the hypotheses, through the evaluation of information technology facilities in one of the individual union affiliations. The complementary data was used to propose further modifications of the integrated Participatory, Argumentative, and Activity Theory design approach. The major contributions of the study are, first, a modified Participatory Design approach to be applied at three levels; in general as a way of overcoming experienced difficulties with the original approach, in the context of entire, large organisations, and in the specific non-profit organisation context. The second contribution is generated knowledge in the new research area of information technology in the non-profit, trade union context, where for instance the presented prototype can be seen as a source of inspiration. Future research directions include further development and formalisation of the integrated Participatory Design approach, as well as actual consequences of implementing information technology in non-profit organisations and trade unions.

Abstract:

Avec l’avènement de la décentralisation au Sahel depuis les années 90 et l’expérience acquise par les pays du Sahel, suite aux sécheresses à répétition1 qui ont affecté leurs zones, des systèmes d’information pour la planification d’actions de développement voient le jour à différentes échelles territoriales. Mais, selon l’avis des communautés de base, ces outils mis en place au niveau local et destinés à l’aménagement du territoire, tant au niveau de la collecte des données que de l’usage du système d’information obtenu, demeurent toujours en deçà de leurs attentes et reste à la disposition et au service exclusifs des décideurs et des techniciens.Or, la prise en compte des connaissances locales des populations, notamment celles relatives à l’information géographique, donne des moyens plus efficients de collecte de données, à partir desquelles peuvent être construits des outils adaptés à la participation et à la négociation entre les différents acteurs et à la planification de projets économiques, ce qui nécessite l’élaboration d’une approche basée sur l’analyse et une gestion participative de l’information géographique issues des connaissances des dites populations.La présente thèse veut accompagner les acteurs locaux des régions sahéliennes dans la mise en oeuvre du développement local de leurs collectivités territoriales, et dans le renforcement de leur citoyenneté par une meilleure participation aux prises de décision. Il s’agira de contribuer à une bonne gestion des ressources naturelles par l’élaboration de plans d’aménagement des différentes zones à travers une gestion participative de l’information géographique locale et la mobilisation des connaissances et savoir-faire locaux.La question est de savoir comment co-définir avec les populations sahéliennes les plans de développement locaux, avec chacune ses spécificités socio-économiques (pasteurs, agropasteurs, agriculteurs, leaders d’opinions, agents d’Etat…) et intégrer leurs connaissances, notamment spatiales, dans la conception d’outils de planification de projets de développement économique.Les résultats de l’expérience menée dans le Nord du Mali ont permis de faire le point surl’état d’avancement des processus de décentralisation, des difficultés de participation despopulations locales dans les prises de décision, des approches du développement local et l’immense connaissance des communautés. Ces résultats ouvrent également des perspectives pour le développement local des collectivités spécifiques du Sahel en les dotant d’outils de planification issus d’une gestion harmonieuse et participative de l’information géographique locale
When decentralization came to the Sahel in the 90s, and with the experienced gained after repeated droughts impacting their countries, information systems for planning development actions were implemented at various levels. But, according to the communities, these tools implemented at the local level for land planning, both for data collection and using the information system thus obtained, fell short of expectations and remain in the exclusive hands of decision-makers and technicians.Yet, when the expertise of the people is taken into account, including geographic information,data collecting is made easier and can help build tools tailored to the participation and negotiation between the various operators and program economic projects, which requires an approach based on the analysis and participative management of geographical management based on the expertise of these peoples.This thesis aims to be a support for local operators in the Sahel region when implementinglocal development plans and empower them by allowing a larger say in the decision making process. The aim is to contribute to a sound natural resources management by the development of management plans in the various areas, through a participative management of local geographical information and by mobilizing local expertise and knowhow.The question is how to define local development plans with the Sahel peoples, each with its own socio-economic specificity (pastoralists, agro-pastoralists, farmers, public figures, state officials ...) and to integrate their expertise, including their spatial expertise, in the developments of planning tools for economic development programmes.The results of the Southern Mali experience was an opportunity to take stock of the progress in the decentralization process, of the difficulties in having local peoples participate in decision making, of local development approaches and the vast expertise of the communities. These results offer prospects for the local development of specific communities in the Sahel, giving them planning tools based on a well-balanced participative management of local geographic expertise

Abstract:

Dans le cours des dernières années, la traçabilité s’est positionnée au cœur de plusieurs enjeux fondamentaux pour les entreprises. Cependant, cette notion est encore aujourd’hui vue comme une contrainte, servant uniquement à respecter des impositions légales et à rappeler des produits non-conformes. Dans ce projet, nous nous sommes attachés à élargir la définition de traçabilité aux domaines de la prévision et de la protection, pour qu’elle ne soit plus perçue comme une obligation supplémentaire à assumer, mais comme un véritable argument d’avantage concurrentiel. Ces travaux de recherche sont consacrés à l’exploitation des informations de traçabilité par l’utilisation des techniques d’intelligence artificielle et de recherche opérationnelle, afin de proposer des actions d’amélioration en production et en logistique. Ils ont été menés en collaboration avec la société ADENTS International, experte en traçabilité. Ce projet est composé de deux principaux axes de travail : l’un portant sur le diagnostic de la criticité d’une production, en fonction des informations de traçabilité et l’autre sur les actions à entreprendre par rapport à ce diagnostic. Dans le premier, nous remarquons l’importance de la notion de dispersion de matières premières et des composants, ainsi que celle des écarts en termes de qualité et de sécurité. Dans le second, nous nous intéressons d’avantage à la notion de rappel de produits, visant une gestion de transformations adaptée en aval de la production, afin de minimiser ces rappels. Pour la mise en place de ces deux grandes activités, nous nous sommes engagés à proposer des modèles et des méthodes flexibles et réactives, pouvant s’adapter à la versatilité ontologique des flux d’informations de traçabilité
The recent product traceability requirements demonstrate an industrial need to improve the information management strategies within traceability systems in order to evolve from reactivity to proactivity. The aim of this work is to exploit the recently available real-time access to traceability information. We propose the utilization of artificial intelligence and operational research techniques to analyse the information and therefore suggest improvement actions. This research project is composed of two main activities: first, the diagnosis of the criticality value associated to a production regarding the traceability information and second, the actions to undertake as a result of this diagnosis. One of the issues studied in this thesis is the problem of minimizing the size of products recall. Initially the problem of raw materials dispersion minimization is analysed. Then a result of the dispersion rate along with other production criteria are evaluated in order to determine a risk level criterion in terms of quality and security that we name “production criticality”. This criterion is used subsequently to optimize deliveries dispatch with the purpose of minimizing the number of batch recalls in case of crisis. This is achieved by implementing flexible and reactive tools

Abstract:

Le système d’identification d’iris est considéré comme l’une des meilleures technologies biométriques. Toutefois, des problèmes liés à la segmentation de l’iris et à la normalisation de la texture de l’iris sont généralement signalés comme principales origines des reconnaissances incorrectes. Dans notre travail, trois contributions principales sont proposées pour améliorer le système d’identification d’iris. Une nouvelle méthode de segmentation est développée. Elle détecte la frontière externe de l’iris par un contour circulaire et la pupille, d’une manière précise, à l’aide d’un modèle de contour actif. Ensuite, une nouvelle méthode de normalisation est proposée. Elle assure une représentation plus robuste et un meilleur échantillonnage de la texture de l’iris comparée aux méthodes traditionnelles. Enfin en utilisant le système d’identification d’iris proposé, la localisation des caractéristiques discriminantes dans une région d’iris est identifiée. Nous vérifions que l’information la plus importante de la région de l’iris se trouve à proximité de la pupille et que la capacité discriminante de la texture diminue avec la distance à la pupille. Les méthodes de segmentation et de normalisation développées sont testées et comparées à un système de référence sur une base de données contenant 2639 images d’iris. Une amélioration des performances de reconnaissance valide l’efficacité du système proposé
Iris identification system is considered among the best biometric technologies. However problems related to the segmentation of the iris and to the normalization of iris templates are generally reported and induce loss of recognition performance. In this work three main contributions are made to the progress of the iris identification system. A new segmentation method is developed. It approximates the outer iris boundary with a circle and segments accurately the inner boundary of the iris by use of an active contour model. Next, a new normalization method is proposed. It leads to a more robust characterization and a better sampling of iris textures compared to traditional normalization methods. Finally using the proposed iris identification system, the location of discriminant characteristics along iris templates is identified. It appears that the most discriminant iris characteristics are located in inner regions of the iris (close to the pupil boundary) and that the discriminant capabilities of these characteristics decreases as outer regions of the iris are considered. The developed segmentation and normalization methods are tested and compared to a reference iris identification system over a database of 2639 iris images. Improvement in recognition performance validates the effectiveness of the proposed system

Abstract:

Em meados de 1998, Charles Hoffman, contador americano, conseguiu desenvolver um novo conceito para a transmissão e gestão da informação financeira em meio digital. Posteriormente denominada de XBRL, sua essência era simples: tentar criar uma forma de comunicação que fosse inteligível e comum tanto para os homens quanto para o computador, sem que para isso fosse necessário imobilizar os conceitos e terminologias financeiras. Sua inovação ganhou respaldo e interesse de diversas instituições responsáveis pela regulação e fiscalização do mercado de capitais norteamericano, assim como de empresas públicas e privadas, que em conjunto, iniciaram medidas a fim de incentivar seu desenvolvimento e sua apreciação prática. No Brasil, seus reflexos ocorreram a partir de 2001, por meio de estudos pioneiros realizados pelo Prof. Edson Luiz Riccio e o TECSI (Laboratório de Gestão da Tecnologia e Sistemas de Informação) do Departamento de Contabilidade e Atuária da FEA/USP, bem como com a publicação de livros e artigos que explicavam ao público o funcionamento e como a inovação se mobilizava entre outros países. Em 2011, o interesse nacional em efetivar sua implantação e adoção ganhou força pela cooperação de diversos agentes interessados, de diversas instituições e com interesses distintos, por meio da criação da taxonomia local. Apesar dos benefícios prometidos, diversos países tiveram dificuldades na aplicação da tecnologia no ambiente interorganizacional, em contraposição com outros tantos que serviram como cases de sucesso para a implementação da XBRL. Grande parte da literatura acredita que, inicialmente, a adoção de uma tecnologia é baseada em escolhas racionais e, posteriormente, sua difusão entre as organizações é explicada pelo processo institucional. Neste trabalho, optou-se pela teoria institucional revisada do modelo conceitual de Swanson e Ramiller (1997), denominado visão organizacional. Por meio dessa perspectiva, o processo institucional é exercido já no período anterior à adoção e difusão de uma tecnologia de sistemas de informações pela criação da visão das diversas organizações institucionais que formam o ambiente. A finalidade do modelo da visão organizacional é entender o processo de interpretação, legitimação e mobilização de recursos para a tecnologia estudada. Ao considerar o XBRL um componente da tecnologia de sistemas de informações, este trabalho apresenta os seguintes problemas de pesquisa: como os arranjos e forças institucionais formam a visão organizacional do XBRL no Brasil? Qual a situação dessa visão organizacional? Por meio de pesquisa qualitativa, foram realizadas, entre dezembro de 2012 a maio de 2013, 9 entrevistas semi-estruturadas com agentes institucionais, de diferentes tipos de organizações, que possuíssem conhecimentos sobre o XBRL. Para análise das entrevistas, optou-se pela categorização semântica seguindo as classes predefinidas no modelo conceitual da visão organizacional. Conclui-se que as organizações com interesse na tecnologia trabalham em estado de cooperação para sua promoção. Avanços foram realizados para a adoção e difusão do XBRL, principalmente na área pública. Entretanto, a visão organizacional precisa demonstrar maior plausibilidade e importância para atrair novos participantes na formação de seu discurso, pois a interpretação, legitimação e mobilização ocorrem em ritmos distintos entre as organizações institucionais.
Around 1998, Charles Hoffman, an American accountant, developed a new concept for the transmission and management of the financial information in digital media. Named XBRL afterwards, its essence was simple: try to create an intelligible and ordinary way of communication both for men and the computer, without the need of hard concepts and financial terminology. This innovation called the attention of many institutions responsible for the regulation and supervision of the American capital market, as well as of public and private companies. Together, they started measures so as to encourage its development and practical appreciation. In Brazil, its repercussions started in 2001, through pioneer studies developed by Prof Edson Luiz Riccio and TECSI (Information Systems and Technology Management Lab) at the Accounting Department of the School of Business, Economics and Accounting - FEA/USP, as well as edition of books and articles that explained the society how it worked and how such an innovation was happening among other countries. In 2001, the national interest to actualize its implementation and adoption enhanced by means of the cooperation between many agents from diverse institutions and with different interests, through the creation of the local taxonomy. Although the promised benefits, many countries had difficulties when applying this technology in the interorganizational environment, if compared with so many others that were success cases for the implementation of XBRL. Great part of literature believes that, initially, the adoption of a technology is based on rational choices and, afterwards, its spread among organizations can be explained by the institutional process. In this research, we chose the revised institutional theory from Swanson & Ramiller (1997) conceptual model, called organizing vision. Through this perspective, the institutional process can be exerted in the period before the adoption and spread of an information systems technology, by creating the vision of the so many institutional organizations taking part in the environment. The aim of the organizing vision is to understand the resources interpretation process, legitimation and mobilization for the studied technology. As we consider XBRL a component of information systems technology, in this research, we present the following problems: how can the institutional strengths and arrangements form the XBRL organizing vision in Brazil? What is the situation of this organizing vision? Through qualitative research, between December 2012 and May 2013, 9 semi-structured interviews were made with institutional agents from different types of organizations, with knowledge of XBRL. To analyse the interviews, we chose the semantic categorization, following the predefined classes of the organizing vision conceptual model. It can be concluded that the organizations interested in technology work in cooperation for its promotion. Progress was made for the adoption and spread of XBRL, mainly in the public area. However, the organizing vision needs to demonstrate more importance and plausibility to attract new participants when forming its discourse, because the interpretation, legitimation and mobilization occur differently among institutional organizations.

Abstract:

For now, vastly growing Web-technology has matured enough to become an attractiveplatform for business applications and organizational information systems. Indeed, largeand small organizations are increasing their investment in Web-based Information Systems(IS) resources, such as Electronic Commerce, Intranets and Extranets. As DIWA(1999) explained that Web technology is often presented as a 'revolution' in informationsystem technologies in the business press, which could propel change from static, hierarchicalstructures to more dynamic, flexible and 'knowledge-based' organizationalforms. To the companies, more and more legacy information and database systems arebeing migrated to Web-based environments.

This research aims to analyse and advise enterprises to be Web-based enterprise withchallenges and opportunities.

During the research, the author investigated a company that were using the Web-based(applications made available via the World Wide Web) information service. For obtainingreliable conclusions and delivering valuable advises, various research methods wereadopted by the author including qualitative research methodology, analysis, interviews,and literature study. Data was collected through lecture review and in-depth interviews.

Undoubtedly, there are some troubles existed in migrating, such as technologies for restructureinformation system structure, resource distribution, benefit analysis, planningand management, operation and maintenance etc.

But still obviously, as the research shows that there are many benefits can be got followsthe implementation of Web-based solution, which includes improving efficiency,modernizing company IT environment, providing better IS/IT systems’ maintenanceand providing more agility and functionality etc.

Abstract:

Näringslivet internationaliseras och globaliseras alltmer samtidigt som ny teknik utvecklas. Kunder ställer allt högre krav på kvalitet och produkternas livscykler blir allt kortare. Detta ställer höga krav på flexibel produktion och korta ställ- och ledtider.

Syftet med denna uppsats är att ta fram en handlingsplan för att förbättra processerna, ar-betsmetoderna och mätsystemet på en reproavdelning inom den grafiska industrin för att öka dess produktivitet.

Utifrån teori från områdena informations- och produktionslogistik har vi byggt upp en referensram och en kunskapsplattform. Detta har legat till grund för processkartläggningen och nulägesanalysen av den reproavdelning som studerades i fallstudien. Utifrån detta arbe-te togs ett förslag på lämpligt mätsystem inklusive mätspecifikationer fram, där hänsyn också togs till de krav som finns på verksamheten, både internt och externt. Det empiriska re-sultatet analyserades utifrån den teoretiska referensram som tagits fram och resulterade i en handlingsplan.

Vi kan identifiera flera områden där det finns potential för att förbättra och effektivisera processerna och arbetsmetoderna för att öka produktiviteten. Dessa har beaktats i handlingsplanen. De viktigaste förbättringsåtgärderna är:

•Eliminering av onödiga aktiviteter

•Effektivisering av informations- och kunskapsspridning

•Implementering av ett lämpligt mätsystem som visar helheten av verksamheten

•Utnyttjande av balanserat styrkort för uppföljning och styrning.

Genom att göra en processkartläggning och se över sina verksamhetsprocesser kan alla företag och organisationer upptäcka flaskhalsar, icke värdeskapande aktiviteter och andra brister som hindrar ett effektivt flöde i verksamheten.

Introduction -- Knowledge and knowledge management systems -- Towards a measurement model of KMS success -- Research methodology -- Data analyses and results -- Conclusions and implications.
Knowledge management is becoming pervasive in organizations. Information technology (IT) has been widely used in organizational knowledge management initiatives, and organizations continue to invest in IT expecting that its use will improve knowledge workers' productivity and organizational performance. -- Knowledge management systems (KMS) are information technology applications designed for knowledge management. The pervasive use of KMS in organizations has raised crucial concerns about the use and value of KMS, which can be expressed as two key questions: - What are the key determinants to the users' acceptance and use of KMS in their daily work? - What is the actual role of KMS in the support of knowledge management? -- For this thesis, empirical research was conducted on KMS success in organizations from a social capital perspective, aiming to tackle these critical questions. Based on a review of existing studies on knowledge management and information systems success, two KMS research models are developed, namely a Socio-Technical System Framework of KMS and an Adaptive Structuration Theory (AST)-based KMS Success Model. The socio-technical framework model of KMS sets out the main KMS components and the interrelationships between these components, presenting a systematic view of KMS in organizations. The AST-based KMS success model represents dynamic and evolutionary KMS in organizations, proposing a system-to-value chain of KMS success linking KMS use to social capital, and to intellectual capital. In the research, the two models have been operationalized; consequently, a set of theoretical hypotheses has been derived. -- A set of survey instruments has been developed or adapted for the study. A preliminary study is used to test, adapt, and modify the new instruments. A web-based cross-sectional survey is conducted, and a sample of 362 knowledge workers from a variety of organizations enables the researcher to further validate the new instruments, assess the research models, and test the hypothesized relationships through structural equation modeling techniques (PLS and LISREL). The results provide clear evidence of the newly developed instruments' reliability, validity, and general applicability, and demonstrate that the research models have good explanatory power for the variances in the KMS use and social capital constructs. Significantly, the study has confirmed that KMS does have the expected significant positive effects on individual social capital development, a critical social infrastructure for knowledge management. The significant positive impacts of KMS use on three dimensions of social capital-structural, relational, and cognitive dimension-have been assessed, and significant findings have been achieved. Moreover, a set of potential critical determinants to users' acceptance and use of KMS has also been assessed in the study. The results have demonstrated the different levels of impacts of these factors on the users' acceptance and use of KMS. -- Based on the research results, recommendations are made for managers, and implications have been drawn for future research. -- Keywords: Knowledge Management Systems (KMS), KMS success measurement, performance-related use of KMS, structural equation modeling, social capital.

Abstract:

IT-system utvecklas idag ofta i globalt distribuerade organisationer. Detta görs för att möta de krav som ställs från omgivningen samt för att finna specialkompetens. En global organisation kan medföra distribuerat arbete, alltså att utvecklingsgrupper sprids över flera platser. Ett problem med detta kan vara att få alla delar av verksamheten att arbeta mot ett gemensamt mål. Koordination – att hantera beroenden mellan element i komplexa organisationer för att möjliggöra effektivt arbete mot ett gemensamt mål – blir då en viktig aktivitet. Att kommunicera över distans i den takt organisationen kräver är en omöjlighet utan att implementera informations- och kommunikationsteknik (IKT) – digitala verktyg med fokus på kommunikation och spridandet av information. Vi vill i denna uppsats undersöka hur koordination sker i distribuerade IT-projekt, samt vilken roll IKT-stöd har vid koordination av distribuerade IT-projekt. Syftet med denna studie är att bidra med kunskap gällande användandet av IKT-stöd för koordination i distribuerade IT- projekt. Vi genomför denna kvalitativa fallstudie hos IFS World Operations AB – en global affärssystemsleverantör. Data har samlats in genom intervjuer med personer i olika roller inom det undersökta it projektet. Vi har ställt de empiriska resultaten i relation till teorier inom områden som koordination, IT-projekt samt IKT. Våra resultat visar att koordination i agila, distribuerade IT-projekt sker på två nivåer; strategisk samt operationell koordination. Dessa syftar att uppnå mål på olika nivåer. Vi har också kunnat dela in koordinationshandlingar i tre typer utvecklade från teori och observationer; ömsesidig anpassning, framväxande standardisering och organisationsförvaltning. Vi kan även sluta oss till att IKT-stöd främst förhåller sig till koordination på tre sätt i ett distribuerat IT-projekt; möjliggörande, medierande samt begränsande. Med stöd av de ovan presenterade resultaten har vi tagit fram faktorer vi funnit påverka möjligheten att koordinera IT-projekt. Dessa är; gruppdynamik, graden av distribution, fasta utvecklingsgrupper, utveckla teknik tillsammans med organisation samt standardiserade kommunikationskanaler.
Information systems are often developed in globally distributed organizations. Many times the reason for being distributed is to meet requirements and demands from the organizations surrounding and to acquire a specialized set of skills. Global organizations may choose to work distributed, which means that development teams are spread out over multiple locations. This can create problems; how do you make all parts of the organization work together towards a common goal? Thus, coordination – The management of interdependent elements in a complex organization so as to enable them to work together effectively toward a specific goal – becomes important. Long distance communication using information and communication technology (ICT) – digital tools with the purpose of endorsing communication and knowledge – is required to coordinate between locations. In this thesis we examine how coordination is performed in distributed IT-projects. We will also address the role that information and communications technology plays in coordination of these projects. The purpose of the study is to contribute with knowledge in the area of using ICT tools for coordinating distributed IT-projects. This qualitative case study was conducted in cooperation with IFS World Operations AB – a global provider of an Enterprise Resource Planning system. Our empirical data has been collected using five interviews, all with different types of roles from within IT-projects. The data has then been put in relation to theories concerning coordination, IT-projects and ICT. Our findings show coordination in distributed, agile software development projects is working on two levels; strategic and operational coordination. The difference lies with the motivation to complete goals on different levels of the organization. We can also conclude that there are three different kinds of means to carry out coordination; Mutual Adjustment, Emerging standardization and organizational management. Concerning the role of ICT in the coordination of distributed IT-projects we have found it to be threefold; enabling, mediating and limiting. Based on these findings we conclude this study by presenting five factors that influence the ability to coordinate distributed IT-projects. These are: group dynamics, level of distribution, fixed development teams, parallel development of technology and organization and standardized communication channels.

Abstract:

Utvecklare tenderar att leverera meningslösa dashboards till användare på olika organisationer. En dashboard är en visuell skärm som presenterar det absolut viktigaste på en enda skärm för att användare därefter ska fatta beslut ifrån. Eftersom det är med hjälp av dashboards som beslut ska fattas är utseendet lika viktigt som att datat är korrekt. En utvecklare har i dagsläget oftast fria tyglar och visualiserar utefter egen erfarenhet och känsla vilket kan få användarna att inte sträva efter att arbeta med dashboarden. Med en användarvänlig dashboard blir det enklare för användaren att fatta sina beslut samt uppskattas det mycket. Studiens resultat tyder på att det finns viktiga områden som utvecklare ska fokusera på för att det ska vara möjligt att uppnå en användarvänlig dashboard. Studien har endast fokuserat på användarvänlighet utifrån designprinciper. Utifrån fokusområden som tagits fram har det också fastställts punkter som tagits fram utifrån vad samtliga användare själva har sagt och tycker gemensamt om. De fokusområden som tagits fram är placering av information, färger och val av grafer. Studiens resultat framställer en tydlig skillnad från vad tidigare litteratur har sagt samt vad användare har gemensamt med litteraturen.
Developers have a tendency to deliver meaningless dashboards to users from different organizations. A dashboard is a visual display that presents the important information on one single screen, for users to make decisions. As it is with the help of dashboards that decisions are to be made, the design is as important as the data is right. Most of the time the developer only throws something up on a dashboard and visualize according to his own experience and feelings, which may cause users not to attempt to work with the dashboard. With a user-friendly dashboard, it becomes easier for the user to make decisions and also becomes more grateful. 2 The results of this study is that there are important areas that developers should focus on in order to be able to achieve a user-friendly dashboard. The study has only focused on user-friendly based on the design principles. Based on the focus areas that have been developed, points have also been established based on what all users themselves have said and share in common. The developed focus areas are the placement of information, colours and choice of graphs. The study´s results make a clear difference from what previous literature has said and what users have in common with the literature.

Abstract:

A saúde pública no país é uma área de alta demanda, dependente de tecnologia cara e de rápida obsolescência, com custos operacional e de manutenção altos, e com uma cobrança de crescimento ininterrupto, decorrente tanto do aumento vegetativo dos usuários, quanto da instabilidade social, quando os desempregados perdem a condição de se utilizar da saúde suplementar e migram para a rede pública. Há um agravamento de tal situação pela dispersão geográfica da população, pelo tamanho do país. O Sistema Único de Saúde, através do PlanejaSUS, tem um esforço continuado de planejar o funcionamento da saúde pública no país, para o que se utiliza, entre outros recursos, dos seguintes sistemas: de Informações sobre Nascidos Vivos; de Informação de Agravos de Notificação; de Informações Hospitalares; e de Informação de Mortalidade. Com o objetivo de identificar o grau de consistência dos mesmos, foi feito um levantamento de periódicos dos últimos 5 anos, de artigos que apontavam tal característica. Mediante a utilização de recortes dos artigos, análise e tabulação de resultados, identificou-se o predomínio de deficiências de pessoal e de qualidade das informações, estas últimas decorrentes das primeiras. Em apenas um caso houve queixa da infraestrutura de tecnologia da informação. Conclui-se pela priorização de trabalhos de persuasão e capacitação de funcionários; por um ajuste na expectativa pela precisão dos sistemas, já que por seu macro dimensionamento, face à dispersão geográfica e ao grande número de pessoas envolvidas, são sistemas com tendência natural à instabilidade; pelo papel que pesquisas como as apresentadas nos artigos podem fazer no controle de tais sistemas; pela consistência apresentada atualmente pelos sistemas, que embora não seja ótima, tem sustentado inúmeras pesquisas cujos resultados são validados por subsídios da literatura e cruzamento de bancos de dados. Aventa-se ainda a possibilidade de, em um trabalho de parceria entre universidades, centros de pesquisa, e o Sistema Único de Saúde, este último estabeleça alguns eixos e categorias, e estimule continuadamente pesquisas voltadas para identificação do nível de consistência dos sistemas mencionados, pesquisas estas cujos resultados poderão funcionar na redução da instabilidade dos mesmos
Public health in the country is a department of high demand, dependent on expensive technology and quick obsolescence, with high operational and maintenance costs, and with a charge of uninterrupted growth, due to both the vegetative growth of users, and the social instability, when the unemployed lose the condition of using additional health system and migrate to the public service. There is a worsening of the situation caused by the geographical dispersion of the population, by the size of the country. The Sistema Único de Saúde (Unified Health System), through the PlanejaSUS, mantain a continued effort of planning the operation of public health in the country, for what it use, among other features, the following systems: information on live borns; reportable diseases information; hospital information; and mortality information. In order to identify the consistency degree of these systems was made a survey of the past 5 years, using articles that pointed such feature. Using cutouts of articles, analysis and tabulation of results, it was identified the predominance of disabilities of personnel and quality of the information, the latter arising out of the first. In only one case there was complaint of information technology infrastructure. It is concluded by the prioritization of work of persuasion and training of employees; by an adjustment in anticipation for the accuracy of the systems, since by its macro scale, given the geographic dispersion and the large number of people involved, that these are systems with natural tendency to instability; the role that research such as those presented in articles can make in the control of such systems; by consistency presented by systems, which although are not great, has sustained extensive research whose results are validated by literature subsidies and databases crossover. It also suggests the possibility of, in a working partnership between universities, research centers, and the Sistema Único de Saúde (Unified Health System), the latter shall establish some axes and categories, and encourage continued research aimed to identifying the level of consistency of the mentioned systems, these research results may work in reducing instability

Abstract:

Com o avanço tecnológico, a valorização da informação, o ritmo acelerado das mudanças e a globalização, características que fazem com que os hospitais (sejam eles, filantrópicos, governamentais ou privados), aliada às exigências cada vez maiores dos pacientes, aumentem a busca pela qualidade na prestação dos serviços. Sobre este pretexto, os hospitais integrantes do Sistema Único de Saúde (SUS), devem elaborar seus respectivos Censos Hospitalares e apresentar seus dados estatísticos ao Ministério da Saúde, baseado nas definições da Portaria no. 312 de 02 de maio de 2002. Estes indicadores não são os únicos necessários ou importantes para a gestão hospitalar, entretanto são considerados como informaçãoes básicas em uma instituição desta natureza. Contudo, a disponibilidade destas informações de forma contínua, sustentável e confiável não tem se mostrado uma tarefa trivial, principalmente devido alguns fatores: falta de registro, registro inadequado e incompleto, falta de padronização na aplicação do vocabulário médico e mudanças constantes nas rotinas administrativas. Em hospitais considerados de grande porte, este problema pode tomar uma extensão ainda maior. Por ser bastante complexo o Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo HCFMUSP, considerado o maior complexo hospitalar da América Latina, com aproximadamente 2.200 leitos e atendendo em média 6.000 pacientes ambulatoriais por dia, constitui um bom objeto para estudo de caso, pois permite que vários desafios em relação ao tratamento da informação, como por exemplo: compartilhamento, conectividade, interoperabilidade e integração, possam surgir de maneira mais acentuada a outros hospitais de menor complexidade. Segundo esta abordagem, o trabalho também pretende explorar o nível de contribuição dos diversos Sistemas de Informação Hospitalar utilizados pelo hospital na obtenção de variáveis, para a composição de informações que serão utilizadas como base para as ações administrativas e avaliação de desempenho. O alto grau de heterogeneidade presente nas soluções no domínio da saúde, distribuídos nos diferentes sistemas de informação, apontam para a v necessidade de compartilhar e troca informações entre ambientes heterogêneos. Neste contexto, a interoperabilidade tem um papel fundamental, pois permite a comunicação de forma transparente entre sistemas e ambientes heterogêneos, autônomos e distribuídos. Foram utilizados neste estudo documentos oficiais relativos aos sistemas de informação assistencial e sua gestão no HC-FMUSP, além de atas de Reuniões do Comitê de Tecnologia da Informação do hospital (CTI). Para a coleta de dados foi aplicada a técnica de entrevista semi-estruturada aos sujeitos responsáveis pelo Serviço de Arquivo Médico SAME de áreas estratégicas do hospital e do Núcleo de Informação em Saúde NIS. A crescente complexidade da assistência à saúde torna premente a necessidade de integração dos sistemas corporativos, bem como a adoção de padrões de registro e procedimentos, porém, não basta resolver as questões somente do ponto de vista tecnológico, o desafio é trabalhar estes problemas considerando toda a sua complexidade e articulando diferentes áreas, em busca de resultados efetivos
With the technological advance, the valuation of the information, the sped up rhythm of the changes and the globalization, characteristics that make with that the hospitals (they are they, philanthropy, governmental or private), allied to the bigger requirements each time of the patients, increase the search for the quality in the installment of the services. On this excuse, the integrant hospitals of the Only System of Health (SUS), must elaborate its respective Hospital Censuses and present its statistical data to the Health department, based on the definitions of governmental decree no. 312 of 02 of May of 2002. These pointers are not only the necessary ones or important for the hospital management, however they are considered as basic information in an institution of this nature. However, the availability of these information of continuous, sustainable and trustworthy form if has not shown a trivial task, mainly had some factors: lack of register, inadequate and incomplete register, constant lack of standardization in the application of the medical vocabulary and changes in the administrative routines. In considered hospitals of great transport, this problem can take an extension still bigger. Of to be sufficiently complex the Hospital of the Clinics of the College of Medicine of the University of Sao Paulo - HCFMUSP, considered the hospital complex greater of Latin America, with approximately 2,200 stream beds and taking care of in average 6,000 patients per day in the ambulatory, constitutes a good object for case study, therefore it allows that some challenges in relation to the treatment of the information, as for example: sharing, connectivity, interoperability and integration, can appear more of accented way to other hospitals of lesser complexity. According to this boarding, the work also intends to explore the level of contribution of the diverse systems of hospital information used by the hospital in the attainment of the variables, for the composition of information that will be used as base for the administrative cases and evaluation of performance. The high degree of present heterogeneity in the solutions in the domain of health distributed in the different systems of information, points with respect to the necessity to share and changes information between heterogeneous environments. In this vii context, the interoperability has a basic paper, therefore it allows to the communication of transparent form between systems and heterogeneous, independent and distributed environments. Official documents to the systems of health care information and its management in the HCFMUSP had been used in this study relative, beyond acts of meetings of the Committee of Technology of the Information of the hospital (CTI). For the collection of data the technique of interview half-structuralized to the responsible citizens for the Service of Medical Archive was applied - SAME of strategical areas of the hospital and the Nucleus of Information in Health - NIS. The increasing complexity of the health care becomes pressing the necessity of integration of the corporative systems, as well as the adoption of register standards and procedures, however, are not enough to only decide the questions of the technological point of view, the challenge are to work these problems considering all its complexity and articulating different areas, in search of effective results

Abstract:

Den digitala transformationen av arbetsplatsen har enligt Bartsch et al. (2020) påskyndas av att många verksamheter till följd av Covid-19-pandemin tvingats övergå till distansarbete. Denna transformation har gjort att många ledare som tidigare lett följare ansikte-mot-ansikte (AMA) på ett kontor tvingats övergå till distansledarskap förmedlat via informations- och kommunikationsteknik (IKT). Både akademiker (Bartsch et al., 2020; Carnevale & Hatak, 2020) och näringslivsidkare (Holmberg & Petrelius, u.å; Deloitte, 2020) menar att övergången till IKT-förmedlat distansledarskap skapar utmaningar för ledare och flertalet forskare menar att kunskapen om e-ledarskap i distala sammanhang är bristande (Avolio et al., 2014; Savolainen, 2014; Bolden & O’Regan, 2016; Contreras et al., 2020; Torre & Sarti, 2020). Denna studies syfte är därför att undersöka hur ledarskapet förändras då det övergår från AMA-ledarskap till IKT-förmedlat distansledarskap samt vilka utmaningar som uppstår. Studien har en kvalitativ ansats med ett interpretativistiskt och konstruktionistiskt förhållningssätt. Den primära datainsamlingsmetoden är semistrukturerade intervjuer och den sekundära datainsamlingsmetoden är innehållsanalys av enkätstudien. Den primära datainsamlingsmetodens intervjurespondenter är åtta operativa chefer med personalansvar på en medelstor svensk myndighet. Respondenterna har tidigare utövat ett AMA-ledarskap och vid övergången till distansläge började de leda med hjälp av IKT-förmedlat distansledarskap. Urvalet av respondenter har gjorts av en personalhandläggare på samma myndighet. Dataanalysen utgjordes av en tematisk analys. Studien kommer fram till att vid övergång från AMA-ledarskap till IKT-förmedlat distansledarskap upplever ledare utmaningar relaterat till tillit, följares välmående, kommunikation, sammanhållning och IT-kompetens. Tre tillitsutmaningar för ledare är: (1) de vet inte om följarna kommer utföra sina arbetsuppgifter, (2) de vet inte om följarnas tillit till dem minskat och (3) de tycker det är utmanande att bygga tillit vid nyanställning. Två utmaningar för ledare relaterade till följares välmående är: (1) de vet inte hur följarna mår och (2) det upplevs inte finnas tillräckligt med tid för att interagera med följarna. Tre kommunikationsutmaningar för ledare är: (1) den informella kommunikationen minskar (2) det är svårt att inleda informella samtal med följare och (3) det är svårt att kommunicera ut deras budskap. Två sammanhållningsutmaningar för ledare är att: (1) hantera att sammanhållningen minskar och (2) hantera att sammanhållningen mellan subgrupper minskar. IT-kompetensutmaningen för ledare är att använda IKT-verktyg för att utöva ledarskapet. Studien visar även att vid övergång från AMA-ledarskap till IKT-förmedlat distansledarskap förändras ledarskapet. Gällande tillitsaspekten kan ledarskapet initialt bli mer kontrollerande och mer närvarofokuserat. Relaterat till följares välmående kan ledarskapet bli mer observerande och ställer högre krav på ledare att möjliggöra sociala kontakter samt boka in frekventa avstämningar. Kommunikationen och sammanhållningen kan påverka ledarskapet och får ledare att inta en roll som facilitator av informella möten. Relaterat till IT-kompetens påverkas utövandet av ledarskapet men vi kan inte se att det förändrar ledarskapet och dess övergripande syfte.
The digital transformation of the workplace was, according to Bartsch et al. (2020), accelerated when organizations were forced to switch to teleworking due to the Covid-19 pandemic. This transformation has forced many leaders who previously led followers face-to-face during office work to switch to remote leadership mediated through information and communication technology (ICT). Both academics (Bartsch et al., 2020; Carnevale & Hatak, 2020) and business actors (Holmberg & Petrelius, u.å; Deloitte, 2020) believe that the transition to ICT-mediated remote leadership creates challenges for leaders and researchers argue that the knowledge of e-leadership in distal contexts is scarce (Avolio et al., 2014; Savolainen, 2014; Bolden & O'Regan, 2016; Contreras et al., 2020; Torre & Sarti, 2020). The purpose of this study is therefore to examine how leadership changes as it transitions from face-to-face leadership to ICT-mediated remote leadership and what challenges arise. The study has a qualitative approach with an interpretative and constructivist approach. The primary data collection method is semi-structured interviews, and the secondary data collection method is a content analysis of survey results. The respondents of the primary data collection method are eight operational managers with personnel responsibilities at a medium-sized Swedish public agency. The respondents have previously carried out face-to-face leadership and during the transition to remote work, they began to lead with the help of ICT-mediated remote leadership. The selection of respondents has been made by a HR coordinator at the same public agency. The data analysis consisted of a thematic analysis. The study concludes that in the transition from face-to-face leadership to ICT-mediated remote leadership, leaders experience challenges related to trust, followers' well-being, communication, cohesion, and IT skills. Three trust challenges for leaders are: (1) they do not know if the followers will perform their duties, (2) they do not know if followers' trust has decreased and (3) they find it challenging to build trust with new employees. Two challenges for leaders related to the well-being of followers are: (1) they do not know if their followers’ wellbeing has decreased and (2) they feel that there is not enough time to interact with the followers. Three communication challenges for leaders are: (1) informal communication decreases (2) it is difficult to initiate informal conversations with followers and (3) it is difficult to communicate their message. Two cohesion challenges for leaders are to: (1) manage that cohesion in general decreases and (2) manage that cohesion between subgroups decreases. One IT skill challenge for leaders is use ICT tools to practice their leadership. The study also shows that leadership changes with the transition from face-to-face leadership to ICT-mediated remote leadership. Regarding the trust aspect, leadership may initially become more controlling, and more presence focused. Related to follower’s well-being, leadership may become more observant and place higher demands on leaders to enable social contacts and book frequent follow-up meetings. Communication and cohesion may affect leadership and force leaders to take on a role as facilitators of informal meetings.

Abstract:

Longe vão os tempos em que a Administração Pública no seu papel fundamental de satisfação das necessidades colectivas e das necessidades individuais - satisfeitas por processos colectivos - se cingia a uma mera administração de fundos, porventura ainda suficientes. Exige-se agora um papel pró-activo da gestão dos recursos disponíveis, para os quais todos contribuímos. O actual gestor tem necessidade de ter indicadores actualizados e disponíveis. Para tal a concepção dos Sistemas de Informação exige uma lógica de integração da informação e uma orientação específica. Através da análise de três Estudos de Caso de Serviços Públicos, considerados no panorama europeu como serviços de excelência, foram identificados os seus sistemas de informação numa abordagem focalizada no modelo de avaliação adoptado - EFQM. O trabalho permitiu concluir que, o modelo conceptual para os Sistemas de Informação destas instituições baseia-se nos critérios de qualidade definidos pelas estratégias. Permitiu ainda compreender que em termos conceptuais o foco dos Sistemas de Informação de suporte à avaliação não está nas alterações de workflow ou de planeamento operacional, mas sim em opções de SYTIC'S que "tragam" o cliente/utente e o accionista/Estado para dentro da instituição. /*** Abstract - There were times that Public Services, in its nuclear role of satisfaction of the collective necessities and the individual necessities - satisfied for collective processes – was only administration of founds. Now we demande a pro-activ altitude on management of resources, for which all we contribute. The modern manager want's available and correct key pointers. For such the conception of the Information Systems demands logic of integrated Information. Through the analysis of three Casy Studies of Public Services, considered in the European panorama as best in class, we had identified its Information system by the view of the assessment model adopted - the EFQM.Model. The work allowed concluding that the conceptual model for the Information System of these institutions is based on quality criteria established by the policy and strategy. It still allowed to understand that the focus of Information System to support assessment actions is not on workflow or operational planning, but in options of IS/AT that bring the client and stakeholders into the organization.

Abstract:

The overall objective of the thesis was to investigate how older family caregivers in rural areas experienced participation in an e-health based caregiver support system. Participants were 95 caregivers allocated to intervention group (n=63) and control group (n=32). The thesis had a mixed method design and is based on four original articles (I-IV). Data was collected through web-camera interviews (I-III), telephone interviews (II,IV) and questionnaires (II,IV) after 1.5 years of using e-health support. Quantitative data was analyzed using comparative statistics, multiple linear regression and logistic regression. Qualitative data was analyzed with content analysis. Article I showed that the caregivers, despite lacking experience from using computers, were able to adopt the new technology, with help from support nurses and family. Caregivers felt e-health helped them to regain social inclusion. Article II had a comparative design, comparing e-health support with conventional caregiver support. Caregivers using e-health were more satisfied with their support and found it to be available, flexible and helping them enhance caregiver competence. Control group caregivers were less satisfied with support and experienced unmet needs. Article III showed that e-health can reduce caregivers’ feelings of isolation. Two themes were created, Expanding the concept of place and Developing networks. Article IV revealed that caregivers used e-health frequently, experienced benefits from using it and had become more independent. Support nurses were disappointed about the decrease in contact with caregivers, and also acknowledged a need for developing the professional nursing role while working with e-health. Conclusions drawn from the findings were that participants experienced benefits from e-health support and it helped them become more independent. Swedish municipalities are obliged to provide caregiver support, the findings from the study are valid to conclude that e-health support are as good as, or even more effective, than conventional support for older family caregivers in rural areas.
Det övergripande syftet vara att undersöka hur äldre anhörigvårdare på landsbygden upplevde att få anhörigstöd via en e-hälsa-tjänst. Avhandlingen hade en mixed method design och bestod av fyra originalarbeten (I-IV). Deltagare i studien var 95 personer, boendes i gles- och landsbygdsområden, som i det egna hemmet vårdade en make eller maka med kronisk sjukdom. Deltagarna var fördelade på interventionsgrupp (n=63) och kontrollgrupp (n=32). Datainsamling skedde efter 1.5 års användning av e-anhhörigstödet, genom web-kamera intervjuer (I-III), telefonintervjuer (II,IV) och frågeformulär (II,IV). Kvantitativa data analyserades genom komparativ statistik, multipel linjär regression och logistisk regression. Kvalitativa data analyserades med innehållsanalys. Artikel I visade att anhörigvårdarna, även om de inte hade någon vana av datorer sedan tidigare, kunde lära sig och bli användare av den teknik och utrustning som ingick i e-anhörigstödet, när de fick hjälp och stöd av anhörigstödjare eller andra. Anhörigvårdarna upplevde att e-anhörigstödet hjälpte dem att återfå social delaktighet. Artikel II hade en komparativ design och jämförde e-anhörigstöd med traditionellt anhörigstöd. De som använde e-anhörigstödet var nöjda med stödet i högre utsträckning än de som fick traditionellt stöd. E-anhörigstödet upplevdes som tillgänglig, flexibelt samt bidrog till att de utvecklade sin kompetens i vårdandet. Kontrollgruppen var mindre nöjd med sitt stöd samt upplevde att de hade behov som inte tillgodoseddes av stödet. Artikel III visade att e-anhörigstöd kan minska anhörigvårdares upplevelse av isolering, dels genom att de upplevde en känsla av att vara på andra platser fast de rent fysiskt befann sig i hemmet, dels genom att de utvecklade sociala nätverk. Artikel IV visade att anhörigvårdarna ofta använde e-anhörigstödet och att de upplevde nytta av att använda det. De blev också mer självständiga vilket ledde till färre kontakter med anhörigstödspersonalen. Personalen kände viss besvikelse över att kontakterna iv med anhöriga minskade och uttryckte att den professionella omvårdnads-rollen behöver utvecklas när e-hälsa införs och tillämpas i vård- och omsorgsarbete. Slutsatser som drogs från fynden i avhandlingen var att anhörigvårdarna hade stor nytta av att använda e-anhörigstöd samt att det hjälpte dem att bli mer självständiga, vilket reducerade deras behov av kontakt med kommunernas anhörigstöd. Sveriges kommuner har en skyldighet enligt lag att tillhandahålla anhörigstöd, med stöd av fynden från den här studien kan man dra slutsatsen att e-anhörigstöd kan fungera lika bra som, ibland till och med effektivare än, traditionellt anhörigstöd.

Abstract:

Even though most clinical information systems (CIS) today are technically sound, the number of successful implementations of these systems is low. For that reason, understanding the characteristics and challenges for organizations implementing CIS is now considered key to successful information technology deployment (Lorenzi & Riley, 1997). Although theory driven information systems models and CIS studies exist, an integrated model to predict a successful CIS has not been evaluated. The purpose of this research was to evaluate the ability of a theoretically-based integrated model of CIS success (CISSM) to predict a successful CIS from the clinicians' perspective. Data were collected and analyzed from 234 registered nurses in 4 hospitals who had used the Cerner PowerChart Admission Health Profile (AHP) longer than 3 months. Construct validity and internal consistency reliability of the 23-item online instrument were established. The results of stepwise multiple regression analyses provided tentative support for the CISSM model.

A presente pesquisa teve como tema subsÃdios para a implantaÃÃo de aterro sanitÃrio. O seu objetivo consistiu em realizar um estudo de caso sobre a implantaÃÃo de aterro sanitÃrio no municÃpio de BaturitÃ. Para tanto, a metodologia de Mc Harg(1969) utilizada na confecÃÃo de mapas temÃticos por meio do software Idrisi, referentes aos fatores ambientais (Geologia, Geomorfologia, Pedologia, Recursos HÃdricos, VegetaÃÃo), seguida de uma reclassificaÃÃo de caracterÃsticas dos mapas a fim de identificar a Ãrea mais adequada para a implantaÃÃo de aterro sanitÃrio, gerando assim, o mapa de aptidÃo final.

The present research it approached as to generate subsidies for implantation of landfills in the BaturitÃ city. For this, the methodology of Ranieri (2000) was used to make thematic maps through of software Idrisi, regarding environmentals factors (use of the natural resources, pedology, hydric resources, geomorphology, vegetation, geology). Later, was made a new classification of characteristics of the maps for identify areas more adjusted for implantation of landfills generating the final map of aptitude. In this manner, the results showed in the research presented a total area of 1.475km2 , regarding the selected area respecting the minimum limits of 2,0 km from the center of the city and maximum limits of 15km, being however only 5,9km2 of it, that is considered adjusted for implantation of landfills through the overlapping of the specified maps. Concluded, therefore, that the study area is not prepared enough for receive the activity of landfills because the its size is minimum still that presenting favorable geoenvironmentals characteristics. In addiction, the results of gravimetrical composition it got high contents of organic substance justifying the necessity of landfills. However, on the basis of the simulation of the final map of aptitude has little area. Concluded, also, that there is the necessity of 1,5 ha of the area for to implant the landfills but the simulation did not point this area all.

Abstract:

En C, une stratégie classique pour implémenter les codes de gestion d'erreur est de faire suivre chaque opération qui peut générer une erreur d'une structure conditionnelle qui teste si l'opération a renvoyé une erreur. Ce stratégie basique, cependant, est sujette à erreurs, et il est courant d'oublier des opérations de nettoyage requises, ainsi que d'oublier de mettre à jour des codes de gestion d'erreur existants lorsque la fonction est étendue avec de nouvelles opérations. De plus, une partie importante du code doit souvent être dupliquée. Un style de programmation, stratégie goto , qui peut réduire en partie certaines de ces difficultés. Pour améliorer la structure des codes de gestion d'erreur dans les logiciels système, nous définissions un algorithme qui permet de transformer les codes de gestion d'erreur implémentés suivant la stratégie basique en codes de gestion d'erreur qui utilisent la stratégie goto. Même lorsque les codes de gestion d'erreurs sont structurés, la gestion et la libération des ressources allouées restent un problème lorsqu'il s'agit d'assurer la robustesse du code système. Dans cette thèse, nous proposons un algorithme microscopique de détection d'omission de libération de ressource, basé sur une analyse principalement intra-procédurale, qui prend en compte les flux et les chemins du code et qui cible et exploite les propriétés des codes de gestion d'erreur. Notre algorithme est résistant aux faux positifs dans l'ensemble des acquisitions de ressources et des opérations de libération, ce qui produit un faible taux de faux positifs dans les rapports renvoyés par l'outil tout en passant à l'échelle.

Abstract:

Patient data in health care have traditionally been used to support direct patient care. Although there is great potential in combining such data with genetic information from patients to improve diagnosis and therapy decisions (i.e. personalized medicine) and in secondary uses such as data mining, this is complex to realize due to technical, commercial and legal issues related with combining and refining patient data. Clinical decision support systems (CDSS) are great catalysts for enabling evidence-based medicine in clinical practice. Although patient data can be the base for CDSS logic, it is often scattered among heterogenous data sources (even in different health care centers). Data integration and subsequent data mining must consider codification of patient data with terminology systems in addition to legal and ethical aspects of using such data. Although computerization of the patient record systems has been underway for a long time, some data is still unstructured. Investigation regarding the feasibility of using electronic patient records (EPR) as data sources for data mining is therefore important. Association rules can be used as a base for CDSS development. Logic representation affect the usability of the systems and the possibility of providing explanations of the generated advice. Several properties of these rules are relatively easy to explain (such as support and confidence), which in itself can improve end-user confidence in advice from CDSS. Information from information sources other than the EPR can also be important for diagnosis and/or treatment decisions. Drug prescription is a process that is particularly dependent on reliable information regarding, among other things, drug-drug interactions which can have serious effects. CDSS and other information systems are not useful unless they are available at the time and location of patient care. This motivates using mobile devices for CDSS. Information structures of interactions affect representation in informatics systems. These structures can be represented using a category theory based implementation of rough sets (rough monads). Development of guidelines and CDSS can be based on existing guidelines with connections to external information systems that validate advice given the particular patient situation (for example, previously prescribed drugs may interact with recommended drugs by CDSS). Rules for CDSS can also be generated directly from patient data but this assumes that such data is structured and representative. Although there is great potential in CDSS to improve the quality and efficiency of health care, these systems must be properly integrated with existing processes in health care (workflows) and with other information systems. Health care workflows manage physical resources such as patients and doctors and can help to standardize care processes and support management decisions through workflow simulation. Such simulations allow information bottle-necks or insufficient resources (equipment, personnel) to be identified. As personalized medicine using genetic information of patients become economically feasible, computational requirements increase. In this sense, distributing computations through web services and system-oriented workflows can complement human-oriented workflows. Issues related to dynamic service discovery, semantic annotations of data, service inputs/outputs affect the feasibility of system-oriented workflow construction and sharing. Additionally, sharing of system-oriented workflows increase the possibilities of peer-review and workflow re-usage.

Abstract:

Travailler en collaboration n’est plus une question mais une réalité, la question qui se pose aujourd’hui concerne la mise en œuvre de la collaboration de façon à ce qu’elle soit la plus réussie possible. Cependant, une collaboration réussie n’est pas facile et est conditionnée par différents facteurs qui peuvent l’influencer. Il est donc nécessaire de considérer ces facteurs au sein du contexte de collaboration pour favoriser l’efficacité de collaboration. Parmi ces facteurs, le collaborateur est un facteur principal, qui est étroitement associé à l’efficacité et à la réussite des collaborations. Le choix des collaborateurs et/ou la recommandation de ces derniers en tenant compte du contexte de la collaboration peut grandement influencer la réussite de cette dernière. En même temps, grâce au développement des technologies de l’information, de nombreux outils numériques de collaboration sont mis à la disposition tels que les outils de mail et de chat en temps réel. Ces outils numériques peuvent eux-mêmes être intégrés dans un environnement de travail collaboratif basé sur le web. De tels environnements permettent aux utilisateurs de collaborer au-delà de la limite des distances géographiques. Ces derniers laissent ainsi des traces d’activités qu’il devient possible d’exploiter. Cette exploitation sera d’autant plus précise que le contexte sera décrit et donc les traces enregistrées riches en description. Il devient donc intéressant de développer les environnements de travail collaboratif basé sur le web en tenant d’une modélisation du contexte de la collaboration. L’exploitation des traces enregistrés pourra alors prendre la forme de recommandation contextuelle de collaborateurs pouvant renforcer la collaboration. Afin de générer des recommandations de collaborateurs dans des environnements de travail collaboratifs basés sur le web, cette thèse se concentre sur la génération des recommandations contextuelles de collaborateurs en définissant, modélisant et traitant le contexte de collaboration. Pour cela, nous proposons d’abord une définition du contexte de collaboration et choisissons de créer une ontologie du contexte de collaboration compte tenu des avantages de l’approche de modélisation en l’ontologie. Ensuite, une similarité sémantique basée sur l’ontologie est développée et appliquée dans trois algorithmes différents (i.e., PreF1, PoF1 et PoF2) afin de générer des recommandations contextuelles des collaborateurs. Par ailleurs, nous déployons l’ontologie de contexte de collaboration dans des environnements de travail collaboratif basés sur le web en considérant une architecture de système des systèmes d’informations du point de vue des environnements de travail collaboratif basés sur le web. À partir de cette architecture, un prototype correspondant d’environnement de travail collaboratif basé sur le web est alors construit. Enfin, un ensemble de données de collaborations scientifiques est utilisé pour tester et évaluer les performances des trois algorithmes de recommandation contextuelle des collaborateurs
Working collaboratively is no longer an issue but a reality, what matters today is how to implement collaboration so that it is as successful as possible. However, successful collaboration is not easy and is conditioned by different factors that can influence it. It is therefore necessary to take these impacting factors into account within the context of collaboration for promoting the effectiveness of collaboration. Among the impacting factors, collaborator is a main one, which is closely associated with the effectiveness and success of collaborations. The selection and/or recommendation of collaborators, taking into account the context of collaboration, can greatly influence the success of collaboration. Meanwhile, thanks to the development of information technology, many collaborative tools are available, such as e-mail and real-time chat tools. These tools can be integrated into a web-based collaborative work environment. Such environments allow users to collaborate beyond the limit of geographical distances. During collaboration, users can utilize multiple integrated tools, perform various activities, and thus leave traces of activities that can be exploited. This exploitation will be more precise when the context of collaboration is described. It is therefore worth developing web-based collaborative work environments with a model of the collaboration context. Processing the recorded traces can then lead to context-aware collaborator recommendations that can reinforce the collaboration. To generate collaborator recommendations in web-based Collaborative Working Environments, this thesis focuses on producing context-aware collaborator recommendations by defining, modeling, and processing the collaboration context. To achieve this, we first propose a definition of the collaboration context and choose to build a collaboration context ontology given the advantages of the ontology-based modeling approach. Next, an ontologybased semantic similarity is developed and applied in three different algorithms (i.e., PreF1, PoF1, and PoF2) to generate context-aware collaborator recommendations. Furthermore, we deploy the collaboration context ontology into web-based Collaborative Working Environments by considering an architecture of System of Information Systems from the viewpoint of web-based Collaborative Working Environments. Based on this architecture, a corresponding prototype of web-based Collaborative Working Environment is then constructed. Finally, a dataset of scientific collaborations is employed to test and evaluate the performances of the three context-aware collaborator recommendation algorithms

Abstract:

The 5th generation mobile telecommunication system (5G) is currently being specified and developed, with large expectations on throughput and efficiency. While 4G and more specifically LTE might constitute a basis of the design of the network, there are some parts that should be improved. One thing to improve is the static signalling that occurs very frequently in a 4G network, of which system information such as synchronization signals, detection of network frequencies, operators, configurations etc. is a part. It has been shown that the static signalling requires both much energy and time-frequency resources. Since the system information is not intended for a single user it is always broadcast so that any user, and any amount of users can read it when needed. 5G will use a technique called massive MIMO, where the base station is equipped with a large number of antennas which can be used to direct signals in space, called beamforming. This thesis presents a new method for distribution of system information that can utilize the beamforming capabilities of massive MIMO. A simple model together with simulated user channel statistics from urban 4G scenarios are used to show that the new method outperforms the classical method of only broadcasting the information, with respect to time-frequency resources. Especially if there are high requirements on the latency of the system information, the new method results in a large gain.

Abstract:

En raison du déploiement massif et progressif des systèmes de vidéosurveillance dans les grandes métropoles, l'analyse a posteriori des vidéos issues de ces systèmes est confrontée à de nombreux problèmes parmi lesquels: (i) l'interopérabilité, due aux différents formats de données (vidéos) et aux spécifications des caméras propres à chaque système ; (ii) le grand temps d'analyse lié à l'énorme quantité de données et métadonnées générées ; et (iii) la difficulté à interpréter les vidéos qui sont parfois à caractère incomplet. Face à ces problèmes, la nécessité de proposer un format commun d'échange des données et métadonnées de vidéosurveillance, de rendre le filtrage et l'interrogation des contenus vidéo plus efficaces, et de faciliter l'interprétation des contenus grâce aux informations exogènes (contextuelles) est une préoccupation incontournable. De ce fait, cette thèse se focalise sur la modélisation des métadonnées multi sources et hétérogènes afin de proposer un filtrage négatif et une interrogation intelligente des données, applicables aux systèmes de vidéosurveillance en particulier et adaptables aux systèmes traitant de grands volumes de données en général. L'objectif dans le cadre applicatif de cette thèse est de fournir aux opérateurs humains de vidéosurveillance des outils pour les aider à réduire le grand volume de vidéo à traiter ou à visionner et implicitement le temps de recherche. Nous proposons donc dans un premier temps une méthode de filtrage dit "négatif", qui permet d'éliminer parmi la masse de vidéos disponibles celles dont on sait au préalable en se basant sur un ensemble de critères, que le traitement n'aboutira à aucun résultat. Les critères utilisés pour l'approche de filtrage négatif proposé sont basés sur une modélisation des métadonnées décrivant la qualité et l'utilisabilité/utilité des vidéos. Ensuite, nous proposons un processus d'enrichissement contextuel basé sur les métadonnées issues du contexte, et permettant une interrogation intelligente des vidéos. Le processus d'enrichissement contextuel proposé est soutenu par un modèle de métadonnées extensible qui intègre des informations contextuelles de sources variées, et un mécanisme de requêtage multiniveaux avec une capacité de raisonnement spatio-temporel robuste aux requêtes floues. Enfin, nous proposons une modélisation générique des métadonnées de vidéosurveillance intégrant les métadonnées décrivant le mouvement et le champ de vue des caméras, les métadonnées issues des algorithmes d'analyse des contenus, et les métadonnées issues des informations contextuelles, afin de compléter le dictionnaire des métadonnées de la norme ISO 22311/IEC 79 qui vise à fournir un format commun d'export des données extraites des systèmes de vidéosurveillance. Les expérimentations menées à partir du framework développé dans cette thèse ont permis de démontrer la faisabilité de notre approche dans un cas réel et de valider nos propositions
Due to the massive and progressive deployment of video surveillance systems in major cities, a posteriori analysis of videos coming from these systems is facing many problems, including the following: (i) interoperability, due to the different data (video) formats and camera specifications associated to each system; (ii) time-consuming nature of analysis due to the huge amount of data and metadata generated; and (iii) difficulty to interpret videos which are sometimes incomplete. To address these issues, the need to propose a common format to exchange video surveillance data and metadata, to make video content filtering and querying more efficient, and to facilitate the interpretation of content using external (contextual) information is an unavoidable concern. Therefore, this thesis focuses on heterogeneous and multi-source metadata modeling in order to propose negative filtering and intelligent data querying, which are applicable to video surveillance systems in particular and adaptable to systems dealing with large volumes of data in general. In the applicative context of this thesis, the goal is to provide human CCTV operators with tools that help them to reduce the large volume of video to be processed or viewed and implicitly reduce search time. We therefore initially propose a so-called "negative" filtering method, which enables the elimination from the mass of available videos those that it is know in advance, based on a set of criteria, that the processing will not lead to any result. The criteria used for the proposed negative filtering approach are based on metadata modeling describing video quality and usability/usefulness. Then, we propose a contextual enrichment process based on metadata from the context, enabling intelligent querying of the videos. The proposed contextual enrichment process is supported by a scalable metadata model that integrates contextual information from a variety of sources, and a multi-level query mechanism with a spatio-temporal reasoning ability that is robust to fuzzy queries. Finally, we propose a generic metadata modeling of video surveillance metadata integrating metadata describing the movement and field of view of cameras, metadata from content analysis algorithms, and metadata from contextual information, in order to complete the metadata dictionary of the ISO 22311/IEC 79 standard, which aims to provide a common format to export data extracted from video surveillance systems. The experiments performed using the framework developed in this thesis showed the reliability of our approach in a real case and enabled the validation of our proposals

Abstract:

Récemment, avec les progrès technologiques rapides que nous observons dans le domaine des Technologies de l'Information et de la Communication (TIC), de nombreux Systèmes d'Information (SI) sont introduits dans nos vies à la maison ou au travail. Cela entraînera des défis croissants pour les utilisateurs, tels que la nécessité de gérer d'énormes quantités de ressources et la difficulté de collaborer avec les autres. Afin de trouver la bonne information au bon moment pour prendre des décisions éclairées, les utilisateurs doivent rechercher des ressources réparties dans de nombreux SI (courriels, réseaux sociaux, pages wiki, notes électroniques, etc.). Le processus de recherche de ressources dans différents SI est coûteux et prend du temps; il doit donc être optimisé. L'émergence des Écosystèmes Numériques (DE) offre aux utilisateurs le potentiel d'améliorer l'accessibilité et la coordination des différents systèmes.D'autre part comparable à un DE, un système de systèmes d'information (SoIS) est composé de SI intégrés qui sont hétérogènes et fonctionnent indépendamment de manière autonome, mais qui sont mis en réseau pour un objectif commun.L'objectif mentionné précédemment, pourrait être l'organisation et le partage de ressources hétérogènes. Cette thèse se concentre sur le passage des Écosystèmes Numériques à un système de systèmes d'information en tant que solution aux défis émergents auxquels sont confrontés les utilisateurs de différents SI dans un contexte de collaboration. Le SoIS donne l'occasion d'explorer comment la collaboration peut être améliorée grâce à une combinaison de différents SI dans l'environnement numérique des organisations. Dans ce contexte, nous avons défini un modèle sémantique et un modèle architectural de SoIS. Nous avons ensuite développé un prototype, appelé MEMORAeSoIS, basé sur ces modèles comme support de collaboration. Ce prototype peut offrir la possibilité d'indexer, de partager, d'annoter et de recommander des ressources importantes provenant de différents SI
Recently, with the rapid technological advancement that we are witnessing in the domain of Information and Communication Technology (ICT), many Information Systems (ISs) are introduced into our lives either at home or at work. That will cause growing challenges for the users, such as the need for managing huge amounts of resources and the difficulty to collaborate with others. In order to find the right information at the right time to make educated decisions, users have to look for resources distributed in many ISs (emails, social networks, wiki pages, electronic notes etc.). The process of searching for resources in different ISs is costly and time-consuming; therefore it needs to be optimized. The emergence of Digital Ecosystems (DE) presents the users with the potential for improving the accessibility and coordination of different systems. On the other hand, comparable to DE, a System of Information Systems (SoIS) is comprised of integrated ISs which are heterogeneous and independently operable on their own but are networked together for a common goal. The goal, as mentioned before, might be organizing and sharing of heterogeneous resources.This thesis focuses on moving from Digital Ecosystems towards a System of Information Systems as a solution to the emergent challenges facing users of different ISs in a collaboration context. The SoIS gives the opportunity to explore how collaboration can be enhanced through a combination of different ISs in the digital environment of organizations. In this context, we defined a semantic model and an architectural model of SoIS. We then developed a prototype, called MEMORAeSoIS, based on these models as collaboration support. This prototype can provide the ability to index, share, annotate, and recommend important resources coming from different ISs.Recently, with the rapid technological advancement that we are witnessing in the domain of Information and Communication Technology (ICT), many Information Systems (ISs) are introduced into our lives either at home or at work. That will cause growing challenges for the users, such as the need for managing huge amounts of resources and the difficulty to collaborate with others. In order to find the right information at the right time to make educated decisions, users have to look for resources distributed in many ISs (emails, social networks, wiki pages, electronic notes etc.). The process of searching for resources in different ISs is costly and time-consuming; therefore it needs to be optimized. The emergence of Digital Ecosystems (DE) presents the users with the potential for improving the accessibility and coordination of different systems. On the other hand, comparable to DE, a System of Information Systems (SoIS) is comprised of integrated ISs which are heterogeneous and independently operable on their own but are networked together for a common goal. The goal, as mentioned before, might be organizing and sharing of heterogeneous resources.This thesis focuses on moving from Digital Ecosystems towards a System of Information Systems as a solution to the emergent challenges facing users of different ISs in a collaboration context. The SoIS gives the opportunity to explore how collaboration can be enhanced through a combination of different ISs in the digital environment of organizations. In this context, we defined a semantic model and an architectural model of SoIS. We then developed a prototype, called MEMORAeSoIS, based on these models as collaboration support. This prototype can provide the ability to index, share, annotate, and recommend important resources coming from different ISs

Abstract:

In an information system which includes plenty of information services, we are always seeking a solution to enhance efficiency and reusability. Emergency medical service system is a classic information system using application integration in which the requirement of information flow transmissions is extremely necessary. We should always ensure this system is running in best condition with highest efficiency and reusability since the efficiency in the system directly affects human life.

The aim of this thesis is to analysis emergency medical system in both qualitative and quantitative ways. Another aim of this thesis is to suggest a method to judge the information flow through the analysis for the system efficiency and the correlations between information flow traffic and system applications.

The result is that system is a main platform integrated five information services. Each of them provides different unattached functions while they are all based on unified information resources. The system efficiency can be judged by a method called Performance Evaluation, the correlation can be judged by multi-factorial analysis of variance method.

Abstract:

Introduktionsprocesser är en viktig del i många verksamheter och speciellt inom restaurangbranschen där nyanställda snabbt ska kunna arbeta självständigt. Restaurangbranschen är också en av de branscherna med högst personalomsättning, vilket kan vara ett problem. Med en genomtänkt och förbättrad introduktion vid nyanställning kan organisationer få sina anställda förstå de mål, visioner och strategier som organisationen satt upp. Detta kan då leda till att personal stannar längre på arbetsplatsen. Målsättningen med denna studie har varit att kartlägga och jämföra hur introduktionen ser ut för nyanställda inom restaurang A och B och vilka åtgärder som kan göras för att förbättra introduktionen med hjälp av etablerade teorier och modeller inom informationslogistik. För att besvara studiens forskningsfrågor har ett deduktivt angreppssätt använts där vi som undersökare gått från empiri till teori. Den data som samlats in kommer från intervjuer och enkätundersökningar som var metodvalen för undersökningen. Två stycken restaurangers introduktionsprocesser för nyanställda kartlades för att se hur de arbetar med introduktionen för nyanställda. Undersökningen gjordes med de ansvariga för respektive introduktion och de personer som varit anställda två år eller kortare. Med hjälp av de intervjuer och enkätundersökning som genomfördes med ansvariga restaurangchefer och anställda inom restaurang A och B kunde en kartläggning av nuläget presenteras. De diskussioner som förts från resultatet av studien har visat att ansvariga för introduktionerna saknar dokumentation för hur processen ska gå till. Introduktion har därför kunnat bli skiftande beroende på hur och när den genomförts. En etablerad introduktionsprocess bör införas, för att varje nyanställd ska få samma förutsättningar att kunna utföra sitt arbete enligt restaurangernas mål, visioner och strategier. De slutsatser som studien presenterar visar på förbättringsförslag genom den empiri som samlats in har kopplats ihop med teori, modeller och tidigare forskning. Dessa förbättringar har skapat introduktionsplan med etablerade processer.
Introduction processes are an important part of many activities, especially in the catering industry, where new employees can quickly work independently. The catering is also one of the sectors with the highest turnover, which could be a problem. With a well thought out and improved introduction for new employees, companies can get their employees to understand the goals, visions and strategies that the company had set up. This can then lead to staff staying longer at work. The aim of this study was to identify and compare how the introduction looks for new employees in the restaurant A and B and the measures that can be done to improve the introduction using the established theories and models in information logistics. To answer the thesis research questions, have a deductive approach been used where we as investigators passed from empiricism to theory. The data collected from interviews and surveys were elections approach for the investigation. Two restaurant's introduction process for new employees was surveyed to see how they work with the introduction of new employees. The survey was conducted with those responsible for each introduction and the people who have been employed for two years or less. With the help of interviews and surveys we conducted with responsible restaurant managers and employees of the restaurant, A and B could be an overview of the current situation presented. The discussions of the results of the study have shown that responsible for the introductions have no documentation of how the process should be conducted. Introduction has therefore been able to be varied depending on how and when it is completed. An established introduction process should be introduced to each new employee should have the same opportunities to carry out their work according to the restaurant's goals, visions and strategies. The conclusions of the thesis present the shows of improvement proposals by the empirical evidence gathered has been linked with the theory, models and previous research. These improvements have created introductory plan with established processes.

Abstract:

Information systems design was investigated and a model was developed aimed obtaining organisational advantages through quality and participation. This was developed by connecting high quality information assurance in an IS to the needs of the organisation and incorporating the users in the development through participation factors.

The model generates a instruction that connects the impact on the individual and organisation when developing an IS to the organisational benefits. Its purpose is to enable the benefits of motivation, awareness and empowerment.

We applied the model using the case study approach for connecting the model to a real life situation. The results provided a blueprint to implement the IS design strategy and may be investigated later to verify if the advantages were reached.

The work is of great interest to project managers, software developers and programmers

Design av informationssystem var undersökt. En modell togs fram med målet att knyta organisatoriska fördelar från kvalitet och medverkan av organisationen i framtagandet av ett IS. Modellen skapades utifrån två ståndpunkter, hög kvalitet på datasäkerhet och de behov som finns inom organisationen samt en inkorporerad medverkan av användarna i framtagandet av IS.

Modellen fungerar som en instruktion med målet att koppla påverkan på organisationen samt individen av att implementera ett IS till de organisatoriska fördelarna genererade av förändringen. Resultatet möjliggör fördelarna av motivation, medvetenhet och empowerment hos organisationen samt individen.

Vi applicerade modellen i ett verkligt företag. Resultatet blev en beskrivning för realisering av en IS designstrategi. Denna strategi bör senare bli utvärderad för att säkerställa att det önskade målet har uppnåtts.

Detta arbete skulle kunna intressera projektledare, mjukvara utvecklare och programmerare.

Abstract:

La confiance et l'incertitude sont deux aspects importants des systèmes distribués. Par exemple, de multiples sources d'information peuvent fournir le même type d'information. Cela pose le problème de sélectionner la source la plus fiable et de résoudre l'incohérence dans l'information disponible. Gérer de front la confiance et l'incertitude constitue un problème complexe et nous développons à travers cette thèse, une solution pour y répondre. La confiance et l'incertitude sont intrinsèquement liés. La confiance concerne principalement les sources d'information alors que l'incertitude est une caractéristique de l'information elle-même. En l'absence de mesures de confiance et d'incertitude, un système doit généralement faire face à des problèmes tels que l'incohérence et l'incertitude. Pour aborder ce point, nous émettons l'hypothèse que les sources dont les niveaux de confiance sont élevés produiront de l'information plus fiable que les sources dont les niveaux de confiance sont inférieurs. Nous utilisons ensuite les mesures de confiance des sources pour quantifier l'incertitude dans l'information et ainsi obtenir des conclusions de plus haut niveau avec plus de certitude.Une tendance générale dans les systèmes distribués modernes consiste à intégrer des capacités de raisonnement dans les composants pour les rendre intelligents et autonomes. Nous modélisons ces composants comme des agents d'un système multi-agents. Les principales sources d'information de ces agents sont les autres agents, et ces derniers peuvent posséder des niveaux de confiance différents. De plus, l'information entrante et les croyances qui en découlent sont associées à un degré d'incertitude. Par conséquent, les agents sont confrontés à un double problème: celui de la gestion de la confiance sur les sources et celui de la présence de l'incertitude dans l'information. Nous illustrons cela avec trois domaines d'application: (i) la communauté intelligente, (ii) la collecte des déchets dans une ville intelligente, et (iii) les facilitateurs pour les systèmes de l'internet du futur (FIWARE - le projet européen n° 285248, qui a motivé la recherche sur nos travaux). La solution que nous proposons consiste à modéliser les composants de ces domaines comme des agents intelligents qui incluent un module de gestion de la confiance, un moteur d'inférence et un système de révision des croyances. Nous montrons que cet ensemble d'éléments peut aider les agents à gérer la confiance aux autres sources, à quantifier l'incertitude dans l'information et à l'utiliser pour aboutir à certaines conclusions de plus haut niveau. Nous évaluons finalement notre approche en utilisant des données à la fois simulées et réelles relatives aux différents domaines d'application
Trust and uncertainty are two important aspects of many distributed systems. For example, multiple sources of information can be available for the same type of information. This poses the problem to select the best source that can produce the most certain information and to resolve incoherence amongst the available information. Managing trust and uncertainty together forms a complex problem and through this thesis we develop a solution to this. Trust and uncertainty have an intrinsic relationship. Trust is primarily related to sources of information while uncertainty is a characteristic of the information itself. In the absence of trust and uncertainty measures, a system generally suffers from problems like incoherence and uncertainty. To improve on this, we hypothesize that the sources with higher trust levels will produce more certain information than those with lower trust values. We then use the trust measures of the information sources to quantify uncertainty in the information and thereby infer high level conclusions with greater certainty.A general trend in the modern distributed systems is to embed reasoning capabilities in the end devices to make them smart and autonomous. We model these end devices as agents of a Multi Agent System. Major sources of beliefs for such agents are external information sources that can possess varying trust levels. Moreover, the incoming information and beliefs are associated with a degree of uncertainty. Hence, the agents face two-fold problems of managing trust on sources and presence of uncertainty in the information. We illustrate this with three application domains: (i) The intelligent community, (ii) Smart city garbage collection, and (iii) FIWARE : a European project about the Future Internet that motivated the research on this topic. Our solution to the problem involves modelling the devices (or entities) of these domains as intelligent agents that comprise a trust management module, an inference engine and a belief revision system. We show that this set of components can help agents to manage trust on the other sources and quantify uncertainty in the information and then use this to infer more certain high level conclusions. We finally assess our approach using simulated and real data pertaining to the different application domains
