Semantic discovery and reuse of business process patterns

Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

Exploring strategic leadership challenges in achieving an ICT enabled transformational government

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel UniversityThis empirical research focuses on exploring the role of strategic leadership in the shift from Electronic Government (eGovernment) to Transformational Government (tGovernment). Despite the fact that many countries have implemented eGovernment, the literature reports a number of themhave failed to reach the promised seamless transformation. Moreover, there is a dearth of research into the domain of tGovernment; the research which exists is limited in extent thus leaving scope for timely and novel research contributions. This thesis reveals that a valuable contribution to knowledge could be derived from exploring the domain of transformational government. The leadership motivationand incentives to conduct a radical government organisational change have become an area of great importance. There is limited research on the strategic role of leadership in achieving transformational government domain; hence, the implications of seamless integration for transformational government have yet to be explored. This research discusses transformational government by using a qualitative, multiple case study research strategy. Data is triangulated and analysed according to its explanatory properties and underlying structural context. This researchextends established norms in literature for tGovernment implementation by incorporating established theories in organisational change from other related disciplines. This is to explain the significance of the underlying philosophical nature of the emerging themes, thus enabling government leaders to create robust strategic proposals for tGovernment. This empirical research is conducted in a Middle Eastern cultural context based in Dubai, United Arab Emirates. The research arrives at several key findings and themesthat contribute to the body of knowledge. A primary finding is the need for a radical change and an innovative managerial approach in using ICT to enable radical change in government organisations. A related finding of this research is that many assumptions underlying the various tGovernment models for transformation fall short to empirically explain the transformational government domain.The government visionary leadership has been proven to be a powerful driver for change in terms of initiating and leading the process for transformational government

Trusted computing or trust in computing? Legislating for trust networks

This thesis aims to address several issues emerging in the new digital world. Using Trusted Computing as the paradigmatic example of regulation though code that tries to address the cyber security problem that occurs, where the freedom of the user to reconfigure her machine is restricted in exchange for greater, yet not perfect, security. Trusted Computing is a technology that while it aims to protect the user, and the integrity of her machine and her privacy against third party users, it discloses more of her information to trusted third parties, exposing her to security risks in case of compromising occurring to that third party. It also intends to create a decentralized, bottom up solution to security where security follows along the arcs of an emergent “network of trust”, and if that was viable, to achieve a form of code based regulation. Through the analysis attempted in this thesis, we laid the groundwork for a refined assessment, considering the problems that Trusted Computing Initiative (TCI) faces and that are based in the intentional, systematic but sometimes misunderstood and miscommunicated difference (which as we reveal results directly in certain design choices for TC) between the conception of trust in informatics (“techno-trust”) and the common sociological concept of it. To reap the benefits of TCI and create the dynamic “network of trust”, we need the sociological concept of trust sharing the fundamental characteristics of transitivity and holism which are absent from techno-trust. This gives rise to our next visited problems which are: if TC shifts the power from the customer to the TC provider, who takes on roles previously reserved for the nation state, then how in a democratic state can users trust those that make the rules? The answer lies partly in constitutional and human rights law and we drill into those functions of TC that makes the TCI provider comparable to state-like and ask what minimal legal guarantees need to be in place to accept, trustingly, this shift of power. Secondly, traditional liberal contract law reduces complex social relations to binary exchange relations, which are not transitive and disrupt rather than create networks. Contract law, as we argue, plays a central role for the way in which the TC provider interacts with his customers and this thesis contributes in speculating of a contract law that does not result in atomism, rather “brings in” potentially affected third parties and results in holistic networks. In the same vein, this thesis looks mainly at specific ways in which law can correct or redefine the implicit and democratically not validated shift of power from customer to TC providers while enhancing the social environment and its social trust within which TC must operate

Information Technology Standards in eResearch: A Conceptual Model of the Primary Adoption Process in Higher Education Organizations

Current research on IT standards tends to focus on their lifecycle: from the development and selection, to their implementation and use. This work proposed an interdisciplinary perspective to analyze primary adoption process in the eResearch domain. As organizations are the core entities in the innovation process, the analysis of IT standards adoption was applied to eResearch infrastructures within higher education organizations. The core argument was built on the adopter s viewpoint as it provides the most explanatory process about adoption. Two international case studies probed the suitability of a model to identify the determinant role of factors like external and internal networks, top management support and organization structure. This dissertation delivers new insights that contribute to bring certainty about one relevant context of standards adoption

Manager’s and citizen’s perspective of positive and negative risks for small probabilities

So far „risk‟ has been mostly defined as the expected value of a loss, mathematically PL, being P the probability of an adverse event and L the loss incurred as a consequence of the event. The so called risk matrix is based on this definition. Also for favorable events one usually refers to the expected gain PG, being G the gain incurred as a consequence of the positive event. These “measures” are generally violated in practice. The case of insurances (on the side of losses, negative risk) and the case of lotteries (on the side of gains, positive risk) are the most obvious. In these cases a single person is available to pay a higher price than that stated by the mathematical expected value, according to (more or less theoretically justified) measures. The higher the risk, the higher the unfair accepted price. The definition of risk as expected value is justified in a long term “manager‟s” perspective, in which it is conceivable to distribute the effects of an adverse event on a large number of subjects or a large number of recurrences. In other words, this definition is mostly justified on frequentist terms. Moreover, according to this definition, in two extreme situations (high-probability/low-consequence and low-probability/high-consequence), the estimated risk is low. This logic is against the principles of sustainability and continuous improvement, which should impose instead both a continuous search for lower probabilities of adverse events (higher and higher reliability) and a continuous search for lower impact of adverse events (in accordance with the fail-safe principle). In this work a different definition of risk is proposed, which stems from the idea of safeguard: (1Risk)=(1P)(1L). According to this definition, the risk levels can be considered low only when both the probability of the adverse event and the loss are small. Such perspective, in which the calculation of safeguard is privileged to the calculation of risk, would possibly avoid exposing the Society to catastrophic consequences, sometimes due to wrong or oversimplified use of probabilistic models. Therefore, it can be seen as the citizen‟s perspective to the definition of risk
