EzWeb/FAST: Reporting on a Successful Mashup-based Solution for Developing and Deploying Composite Applications in the Upcoming Web of Services

Service oriented architectures (SOAs) based on Web Services have attracted a great interest and IT investments during the last years, principally in the context of business-to-business integration within corporate intranets. However, they are nowadays evolving to break through enterprise boundaries, in a revolutionary attempt to make the approach pervasive, leading to what we call a user-centric SOA, i.e. a SOA conceived as a Web of Services made up of compositional resources that empowers end-users to ubiquitously exploit these resources by collaboratively remixing them. In this paper we explore the architectural basis, technologies, frameworks and tools considered necessary to face this novel vision of SOA. We also present the rationale behind EzWeb/FAST: an undergoing EU funded project whose first outcomes could serve as a preliminary proof of concep

Building Adaptive Capacity: An Analysis of Innovations in Information and Communication Technology in Post-Earthquake Haiti

New information and communication technology (ICT) platforms that emerged in the humanitarian response to the 2010 earthquake in Port-au-Prince, Haiti, have been hyped for their ability to spatialize and coordinate disaster relief efforts and, more broadly, to assist short-term mitigation efforts. This research examines the role of recent innovations in ICT in augmenting the adaptive capacity of the Haitian state to carry out mitigation and adaptation planning. Case studies, analysis of communication flows, and interviews were used to assess the state uptake of three different mobile and open source platforms, including: Ushahidi/Noula, SIS-KLOR, and OpenStreetMap. Findings suggest while these new platforms do offer the potential to increase state efficiencies, assess community need, and produce geospatial information, a combination of fear of responsibility, limited resources, lack of local ownership, and path dependency render foreign technologies unsuitable for Haitian use and impede institutionalization. Recommendations focus on shifting practice from investing in foreign technologies to promoting domestic innovation in ICT by strengthening and updating intellectual property legislation and investing in domestic tech firms. This research is relevant to strategic planners, policy-makers, and international organizations working in the IT secto

Free and open source software adoption framework for Swiss small and medium-sized tourist enterprises

The link between IT and the hospitality and tourism industry has been the focus of many research initiatives. As the hospitality and tourism sectors significantly contribute to a nation’s economy, it is imperative that hospitality and tourism enterprises enhance their competitiveness to participate and survive in the global competition. It is common that the tourism and hospitality sector in any economy consists primarily of small and medium-sized enterprises (SMEs). In the case of Switzerland, tourism and hospitality is one of the sectors that employs a significant workforce but is mainly comprised of SMEs. Swiss tourism SMEs are under immense pressure to achieve and maintain a sustainable competitive advantage. Although information technology (IT) adoption has been strongly advocated for tourism enterprises to ensure their success in the global tourism value chain, tourism SMEs have not been utilising IT solutions in their businesses due to the prohibitive costs and a lack of appropriate information about IT solutions. A special class of IT applications known as free and open source software (F/OSS) is growing in prominence and offers scope to provide viable and affordable solutions for various operational and strategic levels for businesses. F/OSSs are socially developed software solutions that are primarily low cost in comparison to their proprietary counterparts. This thesis argues that, in the context of Swiss tourism SMEs, F/OSS-type applications can provide low-cost and high-quality technological solutions, which could assist in improving their competitiveness. Accordingly, the objective of this study is to create an F/OSS adoption framework, which enables analysis of Swiss SMTEs’ willingness to adopt F/OSS applications in their operations. Based on the level of FOSS development and the potential areas for technology adoption within SMTEs areas as outlined in the previous literature, this study proposes and empirically tests an F/OSS adoption model in the context of Swiss tourism SMEs. The model identifies direct and indirect determinants of FOSS adoption which are moderated by demographic factors (age, gender, education and internet experience). The research design consisted of sampling techniques, questionnaire development, qualitative interviews, and pre- and pilot testing of the survey instrument. In order to test the model, data was collected electronically from 152 cross-sectional participants. The data analysis consisted of descriptive analysis and structural equation modelling (SEM). The results of this analysis demonstrated that the predictors of BI to adopt F/OSS explained 23.2 per cent of the variance. Semi-structured interviews were conducted to further validate the research model. In terms of a general F/OSS acceptance model in the context of Swiss SMTEs, based on the findings of the current research, effort expectancy, social influence and community influence are significant determinants of Swiss SMTEs’ behavioural intention towards F/OSS adoption, more than performance expectancy and facilitating conditions. Moreover, the characteristics of Swiss SMTEs and of F/OSS itself could be valid factors influencing the behavioural intentions of Swiss SMTEs. The main contribution of this thesis lies in filling the gap in the research by proposing and testing an F/OSS adoption model that can assess how F/OSS-type applications might be adopted by tourism SMEs. The model contains both direct and indirect determinants of F/OSS adoption. Researchers and practitioners can benefit from the results of this study as it contributes towards our understanding of SMEs’ stance on and intentions to adopt F/OSS

Designing the Sakai Open Academic Environment: A distributed cognition account of the design of a large scale software system

Social accounts of technological change make the flexibility and openness of interpretations the starting point of an argument against technological determinism. They suggest that technological change unfolds in the semantic domain, but they focus on the social processes around the interpretations of new technologies, and do not address the conceptual processes of change in interpretations. The dissertation presents an empirically grounded case study of the design process of an open-source online software platform based on the framework of distributed cognition to argue that the cognitive perspective is needed for understanding innovation in software, because it allows us to describe the reflexive and expansive contribution of conceptual processes to new software and the significance of professional epistemic practices in framing the direction of innovation. The framework of distributed cognition brings the social and cognitive perspectives together on account of its understanding of conceptual processes as distributed over time, among people, and between humans and artifacts. The dissertation argues that an evolving open-source software landscape became translated into the open-ended local design space of a new software project in a process of infrastructural implosion, and the design space prompted participants to outline and pursue epistemic strategies of sense-making and learning about the contexts of use. The result was a process of conceptual modeling, which resulted in a conceptually novel user interface. Prototyping professional practices of user-centered design lent directionality to this conceptual process in terms of a focus on individual activities with the user interface. Social approaches to software design under the broad umbrella of human-centered computing have been seeking to inform the design on the basis of empirical contributions about a social context. The analysis has shown that empirical engagement with the contexts of use followed from conceptual modeling, and concern about real world contexts was aligned with the user-centered direction that design was taking. I also point out a social-technical gap in the design process in connection with the repeated performance challenges that the platform was facing, and describe the possibility of a social-technical imagination.Ph.D

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

Towards a global participatory platform: Democratising open data, complexity science and collective intelligence

The FuturICT project seeks to use the power of big data, analytic models grounded in complexity science, and the collective intelligence they yield for societal benefit. Accordingly, this paper argues that these new tools should not remain the preserve of restricted government, scientific or corporate élites, but be opened up for societal engagement and critique. To democratise such assets as a public good, requires a sustainable ecosystem enabling different kinds of stakeholder in society, including but not limited to, citizens and advocacy groups, school and university students, policy analysts, scientists, software developers, journalists and politicians. Our working name for envisioning a sociotechnical infrastructure capable of engaging such a wide constituency is the Global Participatory Platform (GPP). We consider what it means to develop a GPP at the different levels of data, models and deliberation, motivating a framework for different stakeholders to find their ecological niches at different levels within the system, serving the functions of (i) sensing the environment in order to pool data, (ii) mining the resulting data for patterns in order to model the past/present/future, and (iii) sharing and contesting possible interpretations of what those models might mean, and in a policy context, possible decisions. A research objective is also to apply the concepts and tools of complexity science and social science to the project's own work. We therefore conceive the global participatory platform as a resilient, epistemic ecosystem, whose design will make it capable of self-organization and adaptation to a dynamic environment, and whose structure and contributions are themselves networks of stakeholders, challenges, issues, ideas and arguments whose structure and dynamics can be modelled and analysed.

Development of a Web-based Instructional Module for Interpretation of Craniofacial Cone Beam CT Pathology

The introduction of Cone Beam Computed Tomography (CBCT) in dental practice constitutes a paradigm shift in the way clinicians look at and interpret diagnostic information. With the rapid pace of CBCT development, and with new manufacturers and models appearing in the market each year, it is clear that this technology is assuming an increasingly important role in dental diagnosis. Because of this it will be important to provide a solid foundation on which dental students, general practitioners and specialists alike can build diagnostic skills utilizing this imaging modality. CBCT provides volumetric scans of the patient head that can be visualized in a variety of ways both in 2D and 3D. The newly developed MARCILAN website offers a highly interactive, multimedia rich, web-based, didactic module for interpretation and correlation of 3D anatomical structures as seen on CBCT. However, the current offering does not include a module to aid clinicians in the diagnosis of pathological conditions. The purpose of this study is to develop a web-based instructional module to interpret pathology as presented on cone beam CT images
