Implementing a Secure Annotation Service

Annotation systems enable "value-adding" to digital resources by the attachment of additional data in the form of comments, explanations, references, reviews, corrections and other types of external, subjective remarks. They facilitate group discourse and capture collective intelligence by enabling communities to attach and share their views on particular data and documents accessible over the Web. Annotation systems vary greatly with regard to the types of content they annotate, the extent of collaboration and sharing they allow and the communities which they serve. However within many applications, there is a need to restrict access to the annotations to a particular group of trusted users - in order to protect intellectual property rights or personal privacy. This paper describes a secure, open source annotation system that we have developed that uses Shibboleth and XACML to identify and authenticate users and restrict their access to annotations stored on an Annotea server

User experience in cross-cultural contexts

This dissertation discusses how interdisciplinary UX teams can consider culturally sensitive design elements during the UX design process. It contributes a state-of-the-art meta review on UX evaluation methods, two software tool artifacts for cross-functional UX teams, and empirical insights in the differing usage behaviors of a website plug-in of French, German and Italian users, website design preferences of Vietnamese and German users, as well as learnings from a field trip that focused on studying privacy and personalization in Mumbai, India. Finally, based on these empirical insights, this work introduces the concept culturally sensitive design that goes beyond traditional cross-cultural design considerations in HCI that do not compare different approaches to consider culturally sensitive product aspects in user research

Design and Analysis of an Efficient Friend-to-Friend Content Dissemination System

International audienceOpportunistic communication, off-loading and decentrlaized distribution have been proposed as a means of cost efficient disseminating content when users are geographically clustered into communities. Despite its promise, none of the proposed systems have not been widely adopted due to unbounded high content delivery latency, security and privacy concerns. This paper, presents a novel hybrid content storage and distribution system addressing the trust and privacy concerns of users, lowering the cost of content distribution and storage, and shows how they can be combined uniquely to develop mobile social networking services. The system exploit the fact that users will trust their friends, and by replicating content on friends’ devices who are likely to consume that content it will be possible to disseminate it to other friends when connected to low cost networks. The paper provides a formal definition of this content replication problem, and show that it is NP hard. Then, it presents a community based greedy heuristic algorithm with novel dynamic centrality metrics that replicates the content on a minimum number of friends’ devices, to maximize availability. Then using both real world and synthetic datasets, the effectiveness of the proposed scheme is demonstrated. The practicality of the proposed system, is demonstrated through an implementation on Android smartphones

The housing of soldiers in military barracks with particular reference to Nigeria

The research traces the housing of soldiers in Military Barracks from the time of the Roman Army, and by examining the Contemporary Military Establishment, identifies the changes that have occurred. It notes the advancement in the technology of warfare which necessitates the recruitment of a higher calibre of men into the Military.The survey methodology establishes the use and nature of the questionnaire and the priority evaluation game which was developed to obtain the soldiers' housing priorities. The data collected by the survey from a sample of soldiers is analysed, in order to understand their attitudes towards existing Barrack housing and to identify their expectations in an ideal Barrack housing.The findings show a general dissatisfaction with the existing housing and a preference for the semi- detached house with private backyard. Furthermore, the result indicates that the individual's dissatisfaction with the existing housing is associated with his level of education.The implications resulting from the majority of soldiers now being married are discussed so far as the provision of satisfactory living conditions for troops and their families affect morale and loyalty

Method of Instruction The educational program of the law school is designed to equip its graduates to render the highest quality of legal services, while instilling a sense of professional responsibility. Students are trained in the analysis and solution of legal problems by the application of logical reasoning. The course of study is not designed to teach legal rules, but rather to provide a foundation for the application and analysis of the law and the development of professional skills. The traditional case method of instruction is used in many courses. However, clinical education and courses devoted to various professional skills are increasingly prominent. The full-time faculty is augmented by a number of adjunct faculty members, lawyers and judges, who offer courses in their areas of expertise. An excellent faculty offers a curriculum that is well balanced in theoretical and practical courses and carefully selected to prepare the graduate for the successful practice of law.https://scholarship.richmond.edu/law-catalogues/1068/thumbnail.jp

Multidisciplined Individuals: Defining the Genre

Much of literature is predicated upon the assumption that learning occurring inside the workplace is related to developing expertise associated with the tasks for which the individual is employed and has a background in. This research investigates those individuals who acquire expertise in other disciplines and how the application of that additional expertise changes and enhances the individual and the organisation. By combining perspectives across the disciplinary boundaries and developing multidisciplinary expertise, these individuals demonstrate better methods of achieving business objectives, leading to faster, more imaginative solutions, more frequently, and with significantly less effort. The literature review commenced with defining “multidisciplinary” before addressing communities that cluster around disciplines such as professional societies and Communities of Practice, Aspects of organisational, team and “learning by participation” (Ashton, 2004) literature were also considered. The study took an inductive approach using an ethnographical perspective to data collection and analysis to achieve its aim of determining the existence of multidisciplined individuals and how they acquire additional disciplines. The study used interviewing as its primary method yielding both qualitative and quantitative data from a cross sectional sample set inside a medium sized oil and gas consultancy offering technical and management advice. The disciplines inside the case organisation were mapped to ascertain boundaries where the richest learning opportunities lie. Measuring learning across the disciplines confirmed the existence of multidisciplined individuals with evidence pointing towards the integrated multidisciplined team being the ideal learning environment. The study was able to use Threshold Concepts (Meyer and Land, 2003) to demonstrate the multidisciplinary individual development process. Moreover, having examined the social interaction learning processes the potential negative impacts of Communities of Practice in encouraging this type of multidiscipline approach was highlighted. The study concluded that developing multidisciplined individuals was worthwhile but required organisations to be willing to provide the appropriate platform for such learning by more adventurous individuals who held the appropriate underlying abilities required by the additional discipline (s)
