Anonymous reputation based reservations in e-commerce (AMNESIC)

Online reservation systems have grown over the last recent years to facilitate the purchase of goods and services. Generally, reservation systems require that customers provide some personal data to make a reservation effective. With this data, service providers can check the consumer history and decide if the user is trustable enough to get the reserve. Although the reputation of a user is a good metric to implement the access control of the system, providing personal and sensitive data to the system presents high privacy risks, since the interests of a user are totally known and tracked by an external entity. In this paper we design an anonymous reservation protocol that uses reputations to profile the users and control their access to the offered services, but at the same time it preserves their privacy not only from the seller but the service provider

Integrating information and knowledge for enterprise innovation

It has widely been accepted that enterprise integration, can be a source of socio-technical and cultural problems within organisations wishing to provide a focussed end-to-end business service. This can cause possible “straitjacketing” of business process architectures, thus suppressing responsive business re-engineering and competitive advantage for some companies. Accordingly, the current typology and emergent forms of Enterprise Resource Planning (ERP) and Enterprise Application Integration (EAI) technologies are set in the context of understanding information and knowledge integration philosophies. As such, key influences and trends in emerging IS integration choices, for end-to-end, cost-effective and flexible knowledge integration, are examined. As touch points across and outside organisations proliferate, via work-flow and relationship management-driven value innovation, aspects of knowledge refinement and knowledge integration pose challenges to maximising the potential of innovation and sustainable success, within enterprises. This is in terms of the increasing propensity for data fragmentation and the lack of effective information management, in the light of information overload. Furthermore, the nature of IS mediation which is inherent within decision making and workflow-based business processes, provides the basis for evaluation of the effects of information and knowledge integration. Hence, the authors propose a conceptual, holistic evaluation framework which encompasses these ideas. It is thus argued that such trends, and their implications regarding enterprise IS integration to engender sustainable competitive advantage, require fundamental re-thinking

SOLACE: A framework for electronic negotiations

Copyright @ 2011 Walter de Gruyter GmbHMost existing frameworks for electronic negotiations today are tied to specific negotiation systems for which they were developed, preventing them from being applied to other negotiation scenarios. Thus, the evaluation of electronic negotiation systems is difficult as each one is based on a different framework. Additionally, each developer has to design a new framework for any system to be developed, leading to a ‘reinvention of the wheel’. This paper presents SOLACE—a generic framework for multi-issue negotiations, which can be applied to a variety of negotiation scenarios. In contrast with other frameworks for electronic negotiations, SOLACE supports hybrid systems in which the negotiation participants can be humans, agents or a combination of the two. By recognizing the importance of strategies in negotiations and incorporating a time attribute in negotiation proposals, SOLACE enhances existing approaches and provides a foundation for the flexible electronic negotiation systems of the future

Kesan pembelajaran koperatif terhadap pencapaian pendidikan alam sekitar dalam kalangan pelajar sekolah menengah rendah

Pembelajaran koperatif merupakan satu teknik pembelajaran yang melibatkan pelajar bekerjasama dalam satu kumpulan untuk mencapai matlamat tertentu. Dalam topik Pendidikan Alam Sekitar, pelajar didapati agak lemah dalam memahami sesuatu istilah dan tidak dapat mengaitkan topik dengan pengalaman serta persekitaran mereka. Sebelum ini, pengajaran dan pembelajaran lebih berpusatkan guru. Pembelajaran koperatif pula hanya melibatkan mata pelajaran yang menggunakan makmal atau bengkel. Kajian ini bertujuan untuk meninjau kesan pembelajaran berkumpulan terhadap pencapaian pelajar dalam Pendidikan Alam Sekitar melalui mata pelajaran Geografi. Bentuk kajian yang digunakan ialah kuasi-eksperimen yang dijalankan dengan menggunakan ujian pra dan ujian pasca ke atas kumpulan eksperimen dan kumpulan kawalan. Sampel kajian adalah dua kumpulan pelajar tingkatan 1 dari Sekolah Menengah Kebangsaan Luar Bandar di negeri Johor. Sampel kajian terdiri daripada 37 orang pelajar kumpulan eksperimen dan 35 orang pelajar kumpulan kawalan. Kumpulan eksperimen merupakan kumpulan yang menggunakan kaedah pembelajaran koperatif manakala kumpulan kawalan diajar tanpa pembelajaran koperatif. Instrumen kajian ialah ujian pencapaian, borang soal selidik, jadual pemerhatian dan temubual. Hasil kajian mendapati min pencapaian kumpulan eksperimen adalah tinggi iaitu 18.16 berbanding dengan min kumpulan kawalan, iaitu 13.91. Dapatan kajian menunjukkan terdapat peningkatan pencapaian bagi pelajar yang menjalani pembelajaran koperatif berbanding dengan pelajar yang tidak mengamalkan kaedah pembelajaran tersebut. Pelajar juga dapat menerima penggunaan pembelajaran koperatif dalam proses pengajaran dan pembelajaran. Kesimpulannya, pembelajaran koperatif bukan sahaja dapat meningkatkan hasil malah dapat meningkatkan kualiti proses pengajaran dan pembelajaran

Health informatics domain knowledge analysis: An information technology perspective

Health Informatics is an intersection of information technology, several disciplines of medicine and health care. It sits at the common frontiers of health care services including patient centric, processes driven and procedural centric care. From the information technology perspective it can be viewed as computer application in medical and/or health processes for delivering better health care solutions. In spite of the exaggerated hype, this field is having a major impact in health care solutions, in particular health care deliveries, decision making, medical devices and allied health care industries. It also affords enormous research opportunities for new methodological development. Despite the obvious connections between Medical Informatics, Nursing Informatics and Health Informatics, most of the methodologies and approaches used in Health Informatics have so far originated from health system management, care aspects and medical diagnostic. This paper explores reasoning for domain knowledge analysis that would establish Health Informatics as a domain and recognised as an intellectual discipline in its own right
