Abstract (sommario):

Small and Medium Size Enterprises (SMEs) constitute the backbone of many economies in the world today. This is because they are creating new jobs and contributing positively to their respective economies in which Sweden is not an exception and par-ticularly the municipality of Jonkoping. SMEs invest in IT to gain access to integration of transactions oriented data and business processes.

This thesis, motivational factors for growth in SMEs – (IT perspective) give an overview of how SMEs grow as a result of the introduction and implementation of IT. Information Technology (IT) is seen to be a motivational factor for the growth of SMEs. This is because it acts like an enabler to their businesses and the current business environment.

To answer the research question, I conducted an empirical study of some companies in Jonkoping that are using IT as a motivational factor for growth. Interviews were con-ducted through the use of a structured questionnaire and to a lesser extent, unstructured questionnaire.

Results from studies portrayed that, these companies introduced and implemented IT as a motivational factor for similar reasons though with different objectives.

Abstract (sommario):
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.

Abstract (sommario):
A survey was conducted to investigate motivational and satisfaction differences between Information Systems (IS) and non-IS personnel working in various non-IS organizational departments. The motivational factors of Motivating Potential Score (MPS), Growth Need Strength (GNS), Social Need Strength (SNS), Average Psychological Score (APS), and Overall Satisfaction Score (OSS) were measured. Control for occupational group differences was achieved by classifying survey respondents into one of two job categories: Managerial or Professional/Technical. Significant differences were found in the GNS scores and SNSs of the two job categories. Several implications of the research findings are discussed and recommendations are made with respect to future studies.

Abstract (sommario):
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 (sommario):

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 (sommario):
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 (sommario):

In todays sociaty the use of information systems is wide spread and many corporations and buisnesses both in large and small spread make use of more advanced and sopisticated systems. Larger corporations have their own IT sections that maintain and updates their systems on a daily basis. They have the money and resources for it by how do the small businesses coop with it. How satisfied are the small businesses that are maybe runing on systems that might not be supplying the needs that the business is in need of. In this paper we investigate this question in the form of a questionnaire. The investigation is conducted in a selected part of the market in the swedish city of Växjö. The purpose of the investigation is to see how satisfied 30 businesses are with their information systems. The investigations background comes from a similar american investigation and it’s the papers purpose to compare the results that arose during the american studie with the swedish results to see what diffrences and similaritys there is. The investigation spans over 3 sector of bueisnesses, trade, service and consult. The investigation studies how these 3 sectors satisfaction relates to one and other, how satisfied and disatisfiedthey are in different parts of their IT systems.

Marie Mörndal, Mälardalens Högskola

Problem:

Idag definieras CRM som affärsstrategi i företagen. Denna strategi finns för att kunna skapa en bättre samt en långvarig relation mellan kund och företag. Relationer uppstår då två parter skapar någon form av aktivitet med varandra. Relationsmarknadsföring och Customer relationship management är i stort synonymer, hur kundrelationer bör skötas. Fokusering på kundrelationer i marknaden skulle inte vara möjligt utan ett funktionellt CRM-system. CRM-system ska bidra till en underlättad hantering av kund, men bidrar CRM-systemet självmant till förbättrad kundrelation, eller erbjuder den bara en förenklad kundhantering i företagen? Därför har författarna till denna uppsats valt att ställa följande frågeställning: Hur hanterar ett tjänsteföretag CRM-system och hur påverkar det deras kundrelationer?

Syfte:

Syftet med denna uppsats grundar sig på att beskriva samt analysera hur ett tjänsteföretag hanterar CRM-system och hur det påverkar deras kundrelationer?

Teori & Metod:

Teorin beskriver olika begrepp som relationsmarknadsföring, kundrelationer som sedan leds in i begrepp som CRM-strategi och CRM-system. Det teoretiska kapitlet ger insyn om vad en relation är grundad på och vilken påverkan ett CRM-system har på kundrelationer i ett tjänsteföretag. Studier har gjorts utifrån primär- och sekundär data. Primärdata har tagits från intervjuer medan sekundärdata har tagits från Mälardalens Högskolas databaser samt litteratur som finns i Mälardalens Högskolas bibliotek.

Analys & Slutsats:

I analysen görs olika jämförelser av utvalda delar från uppsatsen som författarna anser vara viktiga för frågeställningen. Dessa är baserade på det teoretiska - och empiriska kapitlet som är baserat på kundrelationer och CRM-system. Författarna har kommit fram till är att det är svårt att fastställa om CRM-systemet självmant bidrar till en förbättrad kundrelation. Detta diskuteras vidare i slutsatsen och mer konkreta svar ges.

Nyckelord:

Abstract (sommario):
Information technology (IT) plays an increasingly important role for individuals, organizations, markets, and society as a whole. IT systems are artefacts (human made objects) designed for various purposes. Given the multiple-purpose characteristics of computers, such artefacts may, for example, support workflows, perform advanced calculations, support human communication and socialization, enable delivery of services and digital products, facilitate learning, or simply entertain. The diverging application areas for IT present a challenge to designers who, as a consequence, have to address increasingly divergent design situations. There have been numerous arguments suggesting that the IT artefact has been 'taken for granted', and needs to be understood and conceptualized better within information systems (IS) research. This thesis is based on the pragmatist notion that one important value of IT resides in its potential to support human collaboration. Such a belief has implications for the development of (1) knowledge aimed for action, change and improvement; (2) knowledge about actions, activities and practices; and (3) knowledge through action, experimentation and exploration. A view of the IT artefact is outlined, showing it as part of a social and technological context. IT artefact design is explained in relation to the induction of social change. The notion of stakeholder-centric design is advocated, along with practical theory to promote a situated understanding of use qualities and design ideals. A set of meta-theoretical implications for design-oriented IS research is proposed. The research process consisted of five inquiries into different IT-reliant social contexts. In the first four inquiries, social and communicative qualities of IT artefacts were assessed, governed primarily by Dewey's notion of inquiry as a theory of knowledge. The fifth inquiry was a large-scale action research project, including interventions into the social setting, and the design and implementation of a new IT artefact into that setting.

Abstract (sommario):
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

Abstract (sommario):
This research explores two separate but related lines of enquiry - the business value of individual applications and the social and organisational impact of information systems. From this research it is clear that information systems have immense potential to change organisations. The conventional view focuses on the value that organisations can obtain through greater efficiency or new activities made possible by specific applications. But experience suggests that many organisations fail to gain the value expected. This research was started with the aim of attaining a greater understanding of the business value that information systems could offer organisations and finding ways by which organisations could assess and realise this value. The research has adopted a variety of methodological approaches and this integrating paper assesses the choices made and locates the papersin relation to the literature on information systems research methodology. The nine research papers taken together demonstrate that is business value is a complex concept and difficult to measure in practice. The research finds that the business and organisational environments are key factors in achieving the business value to be reaped from the range of benefits that each type of IS application offers. The research also demonstrates why IS evaluation practice continues to pose problems for researchers and practitioners. This integrating paper situates the work within the relevant literature on information systems research, assesses the contribution of the research papers to information systems research and concludes with a discussion of future research that flows from this work.

Abstract (sommario):
This PhD project aims to realise a new type of information system, more dynamic and less opaque to its owners, specified with structured natural language models and queried through hypermedia. To accomplish this, we focus on Semantics of Business Vocabulary and Rules (SBVR) as a modelling language, Representational State Transfer (REST) as an interface paradigm and Relational Databases as the persistence mechanism. All three of these technologies have declarative underpinnings, focusing on the ‘what’ rather than the ‘how’, which is why their combination is feasible and effective. By creating appropriate mappings to align these technologies, we create a core platform for Generative Web Information Systems (GWIS). To this end, we present an architecture that binds the three technologies together and adds the concept of a Meta-Process, a way for users to perform process-like workflows without the system having explicit processes defined. The resulting system can gracefully handle unforeseen requests its users may make. To make the Meta-Process feasible, we have created RETRO, a RESTful Transaction Model that allows users to perform more than one action with guarantees of atomicity over the Web. We also describe a service composition framework for Generative Web Information Systems which combines the strengths of the Web with the descriptive capabilities of SBVR to create a Web of Models in which GWIS are native. To validate the conceptual architecture that has been constructed, we have implemented SBVR with Sails, a prototype Generative Web Information System that serves both as a proof of concept and as a basis for future work and exploration of the concept. This model-driven and declarative approach makes semantics and policy integral to the operation of the information system and therefore the individual information system becomes a self-documenting native citizen of the digital ecosystem and the World Wide Web.

Abstract (sommario):
Background Health information systems have emerged as a major component in our response to the trends of rising demands in health care. The insight being gained from the evaluation of those systems can critically influence the shaping of the response. Summative or formative evaluation of health information systems assesses their quality, acceptance, and usefulness, creates insight for improvement, discriminates between options, and refines future development strategies. But the evaluation of health information systems can be challenging due to the propagation of their impacts through multiple socio-technological layers till the ultimate recipients, their heterogeneity and fast evolvement, and the complexity of health care settings and systems. Aim This thesis tries to explain the challenges of evaluation of health information systems with a narrow down on determining evaluation aspects and to propose relevant solutions. The thesis goes for solutions that mitigate heterogeneity and incomparability, recruit or extend available evaluation models, embrace a wide context of application, and promote automation. Method The literature on health information systems evaluation, methods of dealing with heterogeneity in other disciplines of information systems, and ontology engineering were surveyed. Based on the literature survey, the UVON method, based on ontology engineering, was first developed in study 1. The method was applied in FI-STAR, a European Union project in e-Health with 7 use-cases, for summative evaluation of the individual and whole e-health applications. Study 2, extended the UVON method for a formative evaluation during the design phase. Results Application of the UVON method resulted in evaluation aspects that were delivered to the seven use-cases of the FI-STAR project in the form of questionnaires. The resulted evaluation aspects were considered sensible and with a confirming overlap with another highly used method in this field (MAST). No significant negative feedback from the FI-STAR use-case owners (n=7) or the respondents (n=87 patients and n=30 health professionals) was received or observed. Conclusion In the evaluation of health information systems --possibly also in other similarly characterized systems-- ontology engineering methods, such as the proposed UVON method, can be applied to create a flexible degree of unification across a heterogeneous set of evaluation aspects, import evaluation aspects from other evaluation methods, and prioritize between quality aspects in design phase. Ontologies, through their semantic network structures, can capture the extracted knowledge required for evaluation, facilitate computation of that knowledge, promote automation of evaluation, and accommodate further extensions of the related evaluation methods by adding new features to their network structure.

Straub, Bernhard Heinrich. "Ideology and information systems". Thesis, London School of Economics and Political Science (University of London), 1991. http://etheses.lse.ac.uk/1128/.

Testo completo
Abstract (sommario):
Ideology is a political and a sociological term. Thinking about 'system' makes the results of sociological thought appear relevant. The understanding of information systems (IS) as social systems or as phenomena in a social context justifies, therefore, the use of the concept of ideology in the context of IS. As a consequence of this application a series of hypotheses can be formulated about IS and the study of IS. Some of these are taken up in a thought experiment. This experiment is presented in a dialectical mould, consisting of thesis, antithesis and synthesis. In the thesis, the application of the concept of ideology is advocated because it is seen as contributing relevant knowledge to the study of IS. In the antithesis, the above hypothesis is opposed, and consequently the application of the concept of ideology is not advocated. In the synthesis, the application of the concept of ideology is put into a different perspective, where the importance of knowledge is substituted by an emphasis on thinking. Thinking is introduced as the touchstone of relevant knowledge. Its elusive nature is responsible for the elusiveness of claims in systems-thinking and -practice.

Abstract (sommario):
Accounting is an old discipline inherent to any business. Accounting is divided into Financial Accounting (FA) and Management Accounting (MA). Financial Accounting focuses on the pure processing of the economic data. Management Accounting focuses on the decision-making aspects of the accounting. Accounting industry has been tremendously transformed in the past two decades due to the implementation of Enterprise Resource Planning (ERP) systems. These systems integrate and unify an organisation’s business functions and processes into one complex computer system. Previous research suggests that the ERP systems’ main functionality primarily addresses the issues of Financial Accounting and much less the issues of Management Accounting. The purpose of this study is to explore the underlying factors behind the application of the Management Accounting Techniques through the ERP systems and to suggest a further development in the field. Five large Swedish companies were examined through the comparative case studies with semi-structured interviews. This study discovered that MATs were mostly implemented through spreadsheets, BI systems and custom-built software, i.e. outside of the ERP systems. The main reasons were inflexibility and standard design of the ERP systems, that did not fully suit the companies. Additionally, the customization of the ERP systems would be too costly when other tools, such as BI systems or spreadsheets, provided better functionality to a better price. The conclusion of this study is that it is impossible to build a universal ERP system that would suit all kind of companies, however, ERP systems can serve as a common base and a transaction engine for the MA. ERP systems can provide a data structure for the analysis parameters crucial to MA, such as profit centre, cost centre, unit, and other dimensionality aspects. Spreadsheets and BI systems win the MA battle by providing the flexibility, user-friendliness and the acceptable price, required by the users. Therefore, ERP systems must provide good integration possibilities with other software. One can further speculate if ERP system providers choose not to deliver flexible and visually appealing products, since they benefit from the income that the customer education and the customization of an ERP system implies.

Abstract (sommario):

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 (sommario):
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 (sommario):
This thesis presents an approach which the small and medium size firms can use in-house to introduce manufacturing information systems. The approach developed is generic and employs information system design and analysis techniques to guide Small and Medium size Enterprises (SME's) from specification of their need, right through to the implementation of an appropriate solution. Although there are various tools and methodologies that are available for large organisations needs, none are available for SME's. Therefore, the approach presented in this thesis provides original and significant improvements on current practice. The approach emphasises the importance of taking a company wide approach to analyse systems throughout its various departments to establish bad practices and system flaws which may impinge on the performance of the manufacturing operations. The research involved three independent stages. The first stage was the identification of the problem which was realised from two sources: literature survey and interviews with case study company managers. The second stage was the development of a novel approach. The final stage included the validation of the approach by implementing it in five different SMEs in the Devon and Cornwall region. Through the use of this work, company's are encouraged to improve ownership and commitment to the manufacturing information systems by fully involving the relevant company personnel in identifying and resolving various problems. The approach proposed also helps managers understand how the various processes work in other areas of company, and can subsequently lead to improvements in other departments.

Abstract (sommario):
Developments in the technological fields have opened doors to sustain quality of life for making cities smarter and democratic by allowing citizens to play active roles rather being just passive participants along with their governments. Therefore, in this study we have proposed an idealized interaction system- a process used for organizational development based on Interactive Planning Approach, where citizen and government adopt more effective and efficient ways to coordinate, collaborate and communicate for the development and growth of different systems in the city, which ultimately serves as “system to systems”. By using Delphi methodology- a reaserch approach by Norman Dalkey (1946), we invited 25 people representing a wide variety of interests participated in the series two rounds of surveys to suggest more effective and efficient methods of interaction for the citizens and government. All proposed ways after second round of survey are used to design the Idealized Smarter City model – a model of knowledge-based sustainable development. However, structural and behavioral comparisons suggest the need of further improvement to get the proposed system implemented, in review of rapidly increasing population and resulting deteriorating resource availability to sustain the social and technological needs.

Testo completo
Abstract (sommario):
This thesis is about intervening in organisations to improve both operational and strategic computer-based information systems. It addresses a particular situation, in which human activity is seen to be a key factor in the success of the system. A stance is taken regarding current approaches to such development, supported by historical analysis of both the theory and practice of such approaches: in particular, the failure of traditional information systems development methodologies to address these situations is seen to question their validity. A review of existing theory and practice shows that computer-based information systems development appears to be dominated by functionalist, reductionist, engineering methods, marginally challenged by soft, interpretivist approaches. Analysis of the computer-based information systems development domain shows this to be an impoverished view, and indicates that an approach based on social systems is likely to be more representative of the problem situations faced. As a result, computer-based information systems development is taken beyond the 'hard-soft' debate, into a search for theoretical underpinning and practical approaches informed from social theory. However, whilst the theory is readily available, the application of that theory to computer-based information systems development is seen to be problematic. Potential improvement is achieved by the development of an interventionist framework which is based on a branch of social systems theory, that of critical social theory, and which draws heavily on work already undertaken in the domain of management science under the headings of critical systems thinking and total systems intervention. This framework is applied to two case studies and a major, longitudinal action research based investigation. The findings strongly support computer-based information systems development based on social, and especially critical social, theories. These findings are critiqued within the study, and from this emerge clear conclusions, and recommendations for future development.

Abstract (sommario):
An interpretivist investigation of computer-based business information systems was conducted in two commercial companies and two higher education institutes, by using both quantitative questionnaire survey and qualitative interview research methods. The investigation focused on the social and organisational context of information systems development and usage in these organisations. The utility of structured methodologies is now being questioned by some researchers who are calling for alternative approaches, and this investigation draws on that alternative strand of thinking. The collected data primarily reveals that the development and usage of information systems happens in changing organisations, which suggests that the design and usage of information systems must cater for such a changing or dynamic environment. Therefore the data is interpreted using a philosophical outlook encompassing the notion of "living" information systems and Critical Theory, and this philosophical stance regards information technology as liberating human endeavour in organisations. Five sub-concepts and the concept of deferred system's design are derived from the data, which have been formulated to account and cater for change in information systems environments. The concept of deferred system's design encourages the design of information systems which allow for organisational human behaviour, consisting of organisational change, uncertainty, and learning, to be mediated by information technology. A systems design principle called `deferred system's design decisions' is derived to enable designs of tailorable information systems, which may be regarded as one form of living information systems to facilitate such organisational behaviour. An intersubjective theoretical model called the spiral of change model of tailorable information systems is proposed to explain and understand better the changing organisational environment in which information systems must be developed and in which they must function. To inform practice a computer tool is proposed which enables conceptions of " tailorable information systems that employ the principle of deferred system's design decisions and enables modelling changing or dynamic information systems.

Abstract (sommario):
Limited research has been conducted on how system administrators actually can affect information systems (IS) after they have been implemented; hence, this study examines how system administrators can affect IS success in an implemented IS. The study identified a system administrator´s affect on the three IS quality dimensions in the DeLone and McLean IS success model. The empirical findings was based on a single case study where the data was collected through interviews with the system administrator and the system assistants, but also through a questionnaire answered by the users of the IS. The empirical findings suggested that the system administrator can affect IS success through the IS quality dimensions both directly and indirectly. The system administrator´s affect on IS success proved to be highly dependent on the external system vendor and the structure of the internal support unit.

Abstract (sommario):
Complexity and uncertainty have long been problems for organizations of all types. Organizational members do not do a very good job of dealing with the complexity and uncertainty as research shows that when faced with complex situations humans often turn to the same sources of information repeatedly (a practice that will eventually betray them), and/or reduce the amount of scanning that they do (Weick 1995; Boyd and Fulk 1996). Organizations often turn to information systems to help them deal with the complexity, but they often take a techno-centric view of knowledge that does not incorporate the human qualities needed for unstructured decisions (Malhotra 1997; Courtney 2001; Malhotra 2001). Additionally, there are times when the information systems that we are using may hinder the processes of dealing with the complexity (Weick and Meader 1993). Weick's (1995) concept of sensemaking is believed to help us to deal with this complexity. In his work with Meader (1993) he wonders what the effects of a sensemaking support system would have, but he does not have the answer because they state that it has not been asked. This dissertation answers the call of Weick and Meader as well as other scholars that have called for sensemaking and human intuition to be included in our information systems. This is accomplished by viewing sensemaking from an inquiring systems perspective (Churchman 1971) to develop a kernel theory that will be used in the context of design science to develop design requirements and principles for a sensemaking system. These design principles are then used to build an instantiation of the system in the form of SenseMan, a system designed to help a local government agency deal with complexity in the context of software updates. Finally the design is evaluated for its effectiveness in dealing with the complexity of in this context using both quantitative and qualitative methods.

Abstract (sommario):
Logistics and Information System Development are hot topics in today’s business world. Although many studies have been conducted on these two areas, information about logistics costs is still lacking in many companies. Information Systems are tools that, if properly developed, aid organizations in processing data and providing information with speed, accuracy and quality to its intended users. A lacking in the relation between the business world and the Information System’s world was apparent in a studied company’s self-developed Enterprise Resource Planning system, where information about logistics costs was neglected. A case study made in this same studied company, show the importance of seven different logistics costs types and its related information. Using the analysis of the material gathered from both literary work and this case study, it was determined what information about logistics costs is neglected by the manufacturing organization’s self-developed ERP-system. Finally, it was concluded what information on these logistics costs that should be considered by manufacturing organizations for facilitating the understanding of total product cost of specific products and which may not be supported by these systems.

This thesis studies information provision in two contexts: online rating systems and traffic information systems. In the first part of the thesis, we develop a model of Bayesian learning from online reviews and investigate the conditions for asymptotic learning of the quality of a product. Moreover, we characterize the speed of learning under different rating systems and characterize the impact of information provision on the speed of learning. In the model, a sequence of potential customers after observing the ratings of the product, and based on their ex ante valuation, decide whether to purchase. If they purchase, the true quality of the product, their ex ante valuation and ex post valuation determine their overall satisfaction. Given the rating system of the platform, they decide to leave a review as a function of their overall satisfaction. We study learning dynamics under two classes of rating systems: full history, where customers see the full history of reviews, and summary statistics, where the platform reports some summary statistics of past reviews. In both cases, we characterize the asymptotic speed of learning and show that the incentivizes of the platform is aligned with maximizing the speed of learning. We then study the design of rating systems in terms of information collection and information provision schemes. In particular, we identify situations in which providing more information leads to slower learning. In the second part of the thesis, we develop a framework for systematically analyzing how changes in the information sets of users in a traffic network (e.g., due to route guidance systems) impact the traffic equilibrium, and show the conditions under which even those with access to additional information may suffer greater congestion. To this regard, we first introduce a new class of congestion games in which users have differing information sets about the available edges and can only use routes consisting of edges in their information set. We then define the notion of information constrained Wardrop equilibrium for this class of congestion games and establish its existence and uniqueness. Finally, we turn to our main question formulated in the forms of Informational Braess' Paradox (IBP), which extends the classic Braess' Paradox in traffic equilibria. IBP asks whether users receiving additional information can become worse off. We provide a comprehensive answer to this question by providing a tight characterization of network topologies under which IBP emerges.

Mestrado em Desenvolvimento e Cooperação Internacional
This research considers the theoretical and practical link between long-term sustainable development and disaster management. The aim is to develop a theoretical framework and a methodology which allows the use of Geographic Information Systems (GIS) to manage the related information. Literature review leads us to understand development and disaster management as part of a learning cycle. Within this context, a common approach to information management is suggested to support the decision-making process in a cost-effective manner. A “universal” GIS is proposed to integrate information management for development and disaster while exploring the interactions between projects and project and the related geography which is considered a complex reality full of synergies between space, ecosystem, society, culture and economy. Study of academic production, practical implementations, interviews and a limited GIS application (using ArcMap and QGis) are used to endorse the capabilities of this concept. These capabilities are limited by lack of free information and cost of data gathering, interoperability and other technical issues. Open-source and crowdsourcing may solve some limitations while others need further research.

Abstract (sommario):
Hospital Information Systems (HIS) are considering a significant aspect for supporting health care professionals in their work. However, a large number of them are often poor to provide the needed information for accomplishing various work activities in the oriented environment. The aim of this research is to address users’-Administrators and Clinicians- perceptions in order to gain a deeper knowledge about problems they encounter with daily work performed through IS. Additionally, the scope is extended into formulating suggestions through the employment of Soft System Methodology (SSM) that could bring improvements. A qualitative interpretive method with an inductive analysis was followed. Data collection completed through focus group interview sessions and the adoption of SSM three activities in order to acquire the complexity of the problem situation.   Research findings revealed that despite IS Lisora serves as a tool for supporting users work operations, it causes significant problems in their daily operations since the information flow are not feasible. Thus, the research study suggests five feasible and desirable improvements that could improve the overall processes followed by the hospital’s users and bring improvements. In all, SSM was proved to be very efficient in identifying problems that exist. In this way proposed solutions to the problems were enlightened. The general hospital of Preveza shall benefit from the higher efficiency offered by the system, which in turn shall improve the quality of health-care services offered.

Abstract (sommario):

Designing information systems is a complex task. The purpose of this work is to contribute to an improved understanding of the design conditions in order to alleviate the problems that occur due to complexity in the design process. To possibly increase the understanding of the conditions for the design of interactive information systems, this dissertation concerns applying systems approach to the design situation. This is done in order to obtain understanding, but also to be able to identify the consequences and possible benefits of doing so. A literature survey and two extensive interviews have been performed. The material has been analysed, and tentative models of the design situation and its components are presented. These models can be considered general to the design situation and consequences are deduced from them. The result of this work is manifested in the tentative models, which describe the design situation, the designer, the user, the customer and the design. The concepts of complexity and communication have also been thoroughly dealt with.
