Because organizations are making large investments in Information systems (IS), efficient IS project management has been found critical to success. This study examines how the use of incentives can improve the project success. Agency theory is used to: identify motivational factors of project success, help the IS owners to understand to what extent management incentives can improve IS development and implementation (ISD/I). The outcomes will help practitioners and researchers to build on theoretical model of project management elements which lead to project success. Given the principal-agent nature of most significant scale of IS development, insights that will allow for greater alignment of the agent’s goals with those of the principal through incentive contracts, will serve to make ISD/I both more efficient and more effective, leading to more successful IS projects.

This thesis describes research into business user involvement in the information systems application building process. The main interest of this research is in establishing and testing techniques to quantify the relationships between identified success factors and the outcome effectiveness of 'business user development' (BUD). The availability of a mechanism to measure the levels of the success factors, and quantifiably relate them to outcome effectiveness, is important in that it provides an organisation with the capability to predict and monitor effects on BUD outcome effectiveness. This is particularly important in an era where BUD levels have risen dramatically, user centred information systems development benefits are recognised as significant, and awareness of the risks of uncontrolled BUD activity is becoming more widespread. This research targets the measurement and prediction of BUD success factors and implementation effectiveness for particular business users. A questionnaire instrument and analysis technique has been tested and developed which constitutes a tool for predicting and monitoring BUD outcome effectiveness, and is based on the BUDES (Business User Development Effectiveness and Scope) research model - which is introduced and described in this thesis. The questionnaire instrument is designed for completion by 'business users' - the target community being more explicitly defined as 'people who primarily have a business role within an organisation'. The instrument, named BUD ESP (Business User Development Effectiveness and Scope Predictor), can readily be used with survey participants, and has been shown to give meaningful and representative results.

Information systems are corporate resources, therefore information systems development must be aligned with corporate strategy. This thesis proposes that effective strategic alignment of information systems requires information systems development, information systems planning and strategic management to be united. Literature in these areas is examined, breaching the academic boundaries which separate these areas, to contribute a synthesised approach to the strategic alignment of information systems development. Previous work in information systems planning has extended information systems development techniques, such as data modelling, into strategic planning activities, neglecting techniques of strategic management. Examination of strategic management in this thesis, identifies parallel trends in strategic management and information systems development; the premises of the learning school of strategic management are similar to those of soft systems approaches to information systems development. It is therefore proposed that strategic management can be supported by a soft systems approach. Strategic management tools and techniques frame individual views of a strategic situation; soft systems approaches can integrate these diverse views to explore the internal and external environments of an organisation. The information derived from strategic analysis justifies the need for an information system and provides a starting point for information systems development. This is demonstrated by a composite framework which enables each information system to be justified according to its direct contribution to corporate strategy. The proposed framework was developed through action research conducted in a number of organisations of varying types. This suggests that the framework can be widely used to support the strategic alignment of information systems development, thereby contributing to organisational success.

This research concerns information systems and information systems development. The thesis describes an approach to information systems development called Multiview. This is a methodology which seeks to combine the strengths of a number of different, existing approaches in a coherent manner. Many of these approaches are radically different in terms of concepts, philosophy, assumptions, methods, techniques and tools. Three case studies are described presenting Multiview 'in action'. The first is used mainly to expose the strengths and weaknesses of an early version of the approach discussed in the thesis. Tools and techniques are described in the thesis which aim to strengthen the approach. Two further case studies are presented to illustrate the use of this second version of Multiview. This is not put forward as an 'ideal methodology' and the case studies expose some of the difficulties and practical problems of information systems work and the use of the methodology. A more contingency based approach to information systems development is advocated using Multiview as a framework rather than a prescriptive tool. Each information systems project and the use of the framework is unique, contingent on the particular problem situation. The skills of different analysts, the backgrounds of users and the situations in which they are constrained to work have always to be taken into account in any project. The realities of the situation will cause departure from the 'ideal methodology' in order to allow for the exigencies of the real world. Multiview can therefore be said to be an approach used to explore the application area in order to develop an information system.

Computer modeling is a perspective method for optimal design of prosthesis and orthoses. The study is oriented to develop modular ankle foot orthosis (MAFO) to assist the very frequently observed gait abnormalities relating the human ankle-foot complex using CAD modeling. The main goal is to assist the ankle- foot flexors and extensors during the gait cycle (stance and swing) using torsion spring. Utilizing 3D modeling and animating open source software (Blender 3D), it is possible to generate artificially different kind of normal and abnormal gaits and investigate and adjust the assistive modular spring driven ankle foot orthosis.

In this paper we try to present how information technologies as tools for the creation of digital bilingual dictionaries can help the preservation of natural languages. Natural languages are an outstanding part of human cultural values and for that reason they should be preserved as part of the world cultural heritage. We describe our work on the bilingual lexical database supporting the Bulgarian-Polish Online dictionary. The main software tools for the web- presentation of the dictionary are shortly described. We focus our special attention on the presentation of verbs, the richest from a specific characteristics viewpoint linguistic category in Bulgarian.

Background: The Medical Education Partnership Initiative, has helped to mitigate the digital divide in Africa. The aim of the study was to assess the level of access, attitude, and training concerning meaningful use of electronic resources and EBM among medical students at an African medical school. Methods: The study involved medical students at the University of Zimbabwe College of Health Sciences, Harare. The needs assessment tool consisted of a 21-question, paper-based, voluntary and anonymous survey. Results: A total of 61/67 (91%), responded to the survey. 60% of the medical students were ‘third-year medical students’. Among medical students, 85% of responders had access to digital medical resources, but 54% still preferred printed medical textbooks. Although 25% of responders had received training in EBM, but only 7% found it adequate. 98% of the participants did not receive formal training in journal club presentation or analytical reading of medical literature, but 77 % of them showed interest in learning these skills. Conclusion: Lack of training in EBM, journal club presentation and analytical reading skills have limited the impact of upgraded technology in enhancing the level of knowledge. This impact can be boosted by developing a curriculum with skills necessary in using EBM.

Una delle realtà criminali che ha maggiormente fruito delle innovazioni introdotte dalla “società dell’Informazione” è, senza dubbio, quella dell’abuso sessuale sui minori. Tra le differenti forme di abuso sessuale sui minori, si è scelto di affrontare il fenomeno della pedopornografia online in ragione del preoccupante diffondersi di questa forma di criminalità che, grazie all’implementazione delle tecnologie dell’informazione, ha assunto caratteri nuovi, per alcuni versi difformi dai “tradizionali” profili della pedofilia, che sollevano interrogativi e nuove sfide sia sul versante della repressione di queste condotte illecite, sia sul piano della prevenzione. Nell'ambito di questo contributo, saranno esaminate in particolare le politiche penali elaborate in due diverse realtà nazionali, l'Italia e la Francia, a partire da differenti punti di vista e ponendo particolare attenzione agli strumenti, normativi ed operativi, introdotti per reprimere lo sfruttamento sessuale dei minori legato alla dimensione virtuale.
