Factor affecting the adoption of information and communication technology in the tourism sector of the Maldives

For many Small Island Developing States (SIDS) like the Maldives, tourism is a significant area of business. The increasing reliance on information and communication technology (ICT) in the tourism industry has become one of the major challenges facing developing countries, especially the SIDS. The success of the tourism industry in SIDS is closely associated with the use of ICT applications and e-business techniques. This research studied the extent of utilisation of e-business and the issues that arise in its adoption and use in the organizations that make up the tourism industry of the Maldives. A theoretical framework was developed to identify the issues pertaining to use of ICT and e-business. The research was qualitative in nature and used a combination of grounded theory and multi-grounded theory approaches for data analysis in order to develop a new theoretical framework. This inductive process resulted in three emergent themes: representing three domains Country, Sector, and Information Systems (IS). ICT or e-business adoption and integration in the tourism organizations is affected by Sector, which is by and large influenced by the Country, which in turn impacts on the IS domain. These three complementary themes formed a new theoretical framework, generating a set of factors and institutional forces affecting the adoption and integration of ICT or e-business in the tourism organisations of the Maldives. This study contributes to our understanding of e-business in developing countries, in particular to small island developing states with islandness, like the Maldives

Ein Integrations- und Darstellungsmodell für verteilte und heterogene kontextbezogene Informationen

Die "Kontextsensitivität" genannte systematische Berücksichtigung von Umweltinformationen durch Anwendungssysteme kann als Querschnittsfunktion im betrieblichen Umfeld in vielen Bereichen einen Nutzen stiften. Wirklich praxistaugliche kontextsensitive Anwendungssysteme, die sich analog zu einem mitdenkenden menschlichen Assistenten harmonisch in die ablaufenden Vorgänge in der Realwelt einbringen, haben einen enormen Bedarf nach umfassenden, d.h. diverse Aspekte der Realwelt beschreibenden Kontextinformationen, die jedoch prinzipbedingt verteilt in verschiedenen Datenquellen, etwa Kontexterfassungssystemen, Endgeräten sowie prinzipiell auch in beliebigen anderen, z.T. bereits existierenden Anwendungen entstehen. Ziel dieser Arbeit ist die Verringerung der Komplexität des Beschaffungsvorganges von verteilten und heterogenen Kontextinformationen durch Bereitstellung einer einfach verwendbaren Methode zur Darstellung eines umfassenden, aus verteilten und heterogenen Datenquellen zusammengetragenen Kontextmodells. Im Besonderen werden durch diese Arbeit zwei Probleme addressiert, zum einen daß ein Konsument von umfassenden Kontextinformationen mehrere Datenquellen sowohl kennen und zugreifen können und zum anderen über die zwischen den einzelnen Kontextinformationen in verschiedenen Datenquellen existierenden, zunächst nicht modellierten semantischen Verbindungen Bescheid wissen muß. Das dazu entwickelte Kontextinformationsintegrations- und -darstellungsverfahren kombiniert daher ein die Beschaffung und Integration von Kontextinformationen aus diversen Datenquellen modellierendes Informationsintegrationsmodell mit einem Kontextdarstellungsmodell, welches die abzubildende Realweltdomäne basierend auf ontologischen Informationen durch in problemspezifischer Weise erweiterte Verfahren des Semantic Web in einer möglichst intuitiven, wiederverwendbaren und modularen Weise modelliert. Nach einer fundierten Anforderungsanalyse des entwickelten Prinzips wird dessen Verwendung und Nutzen basierend auf der Skizzierung der wichtigsten allgemeinen Verwendungsmöglichkeiten von Kontextinformationen im betrieblichen Umfeld anhand eines komplexen betrieblichen Anwendungsszenarios demonstriert. Dieses beinhaltet ein Nutzerprofil, das von diversen Anwendungen, u.a. einem kontextsensitiven KFZ-Navigationssystem, einer Restaurantsuchanwendung sowie einem Touristenführer verwendet wird. Probleme hinsichtlich des Datenschutzes, der Integration in existierende Umgebungen und Abläufe sowie der Skalierbarkeit und Leistungsfähigkeit des Verfahrens werden ebenfalls diskutiert.Context-awareness, which is the systematic consideration of information from the environment of applications, can provide significant benefits in the area of business and technology. To be really useful, i.e. harmonically support real-world processes as human assistants do it, practical applications need a comprehensive and detailed contextual information base that describes all relevant aspects of the real world. As a matter of principle, comprehensive contextual information arises in many places and data sources, e.g. in context-aware infrastructures as well as in "normal" applications, which may have knowledge about the context based on their functionality to support a certain process in the real world. This thesis facilitates the use of contextual information by reducing the complexity of the procurement process of distributed and heterogenous contextual information. Particularly, it addresses the two problems that a consumer of comprehensive contextual information needs to be aware of and able to access several different data sources and must know how to combine the contextual information taken from different and isolated data sources into a meaningful representation of the context. Especially the latter information cannot be modelled using the current state of the art. These problems are addressed by the development of an integration and representation model for contextual information that allows to compose comprehensive context models using information inside distributed and heterogeneous data sources. This model combines an information integration model for distributed and heterogenous information (which consists of an access model for heterogeneous data sources, an integration model and an information relation model) with a representation model for context that formalizes the representation of the respective real world domain, i.e. of the real world objects and their semantic relations in an intuitive, reusable and modular way based on ontologies. The resulting model consists of five layers that represent different aspects of the information integration solution. The achievement of the objectives is rated based on a requirement analysis of the problem domain. The technical feasibility and usefulness of the model is demonstrated by the implementation of an engine to support the approach as well as a complex application scenario consisting of a user profile that integrates information from several data sources and a couple of context-aware applications, e.g. a context-aware navigation system, a restaurant finder application as well as an enhanced tourist guide that use the user profile. Problems regarding security and social effects, the integration of this solution into existing environments and infrastructures as well as technical issues like the scalability and performance of this model are discussed too

What to Expect from Software Experience Exploitation

Software quality management and quality assurance are disciplines that require substantial knowledge of the methods and techniques to be applied. More important than a solid knowledge of methodology, however, is the ability to judge feasibility of approaches, and to tailor activities to the business unit culture and constraints. Software quality activities must be carefully integrated into an existing company or business culture. Making informed decisions requires more than knowledge - it calls for experience of what works and what does not work in a given environment. Experienced quality agents are a scarce resource. Exploiting a scarce resource - like experiences in software quality - more effectively is a straight-forward concept. Five years ago, DaimlerChrysler set up a large research project with business units, called SEC (Software Experience Center). Its purpose was to explore opportunities for learning from experiences within and across different business units. Unlike more general approaches of knowledge management, SEC was entirely devoted to software processes: software development, software acquisition, and in particular software quality in both development and acquisition settings. However, not all expectations that are often related to experience exploitation are realistic. In SEC, some of our initial expectations were met, others were not. This talk reports and reflects on our attempts to capture, engineer, and reuse experiences in the realm of software quality and software process improvement
