On the standardisation of Web service management operations

Given the current interest in TCP/IP network management research towards Web services, it is important to recognise how standardisation can be achieved. This paper mainly focuses on the standardisation of operations and not management information. We state that standardisation should be done by standardising the abstract parts of a WSDL document, i.e. the interfaces and the messages. Operations can vary in granularity and parameter transparency, creating four extreme operation signatures, all of which have advantages and disadvantages

Distributed Computing Grid Experiences in CMS

The CMS experiment is currently developing a computing system capable of serving, processing and archiving the large number of events that will be generated when the CMS detector starts taking data. During 2004 CMS undertook a large scale data challenge to demonstrate the ability of the CMS computing system to cope with a sustained data-taking rate equivalent to 25% of startup rate. Its goals were: to run CMS event reconstruction at CERN for a sustained period at 25 Hz input rate; to distribute the data to several regional centers; and enable data access at those centers for analysis. Grid middleware was utilized to help complete all aspects of the challenge. To continue to provide scalable access from anywhere in the world to the data, CMS is developing a layer of software that uses Grid tools to gain access to data and resources, and that aims to provide physicists with a user friendly interface for submitting their analysis jobs. This paper describes the data challenge experience with Grid infrastructure and the current development of the CMS analysis system

Architecture of a consent management suite and integration into IHE-based regional health information networks

<p>Abstract</p> <p>Background</p> <p>The University Hospital Heidelberg is implementing a Regional Health Information Network (RHIN) in the Rhine-Neckar-Region in order to establish a shared-care environment, which is based on established Health IT standards and in particular Integrating the Healthcare Enterprise (IHE). Similar to all other Electronic Health Record (EHR) and Personal Health Record (PHR) approaches the chosen Personal Electronic Health Record (PEHR) architecture relies on the patient's consent in order to share documents and medical data with other care delivery organizations, with the additional requirement that the German legislation explicitly demands a patients' opt-in and does not allow opt-out solutions. This creates two issues: firstly the current IHE consent profile does not address this approach properly and secondly none of the employed intra- and inter-institutional information systems, like almost all systems on the market, offers consent management solutions at all. Hence, the objective of our work is to develop and introduce an extensible architecture for creating, managing and querying patient consents in an IHE-based environment.</p> <p>Methods</p> <p>Based on the features offered by the IHE profile Basic Patient Privacy Consent (BPPC) and literature, the functionalities and components to meet the requirements of a centralized opt-in consent management solution compliant with German legislation have been analyzed. Two services have been developed and integrated into the Heidelberg PEHR.</p> <p>Results</p> <p>The standard-based Consent Management Suite consists of two services. The Consent Management Service is able to receive and store consent documents. It can receive queries concerning a dedicated patient consent, process it and return an answer. It represents a centralized policy enforcement point. The Consent Creator Service allows patients to create their consents electronically. Interfaces to a Master Patient Index (MPI) and a provider index allow to dynamically generate XACML-based policies which are stored in a CDA document to be transferred to the first service. Three workflows have to be considered to integrate the suite into the PEHR: recording the consent, publishing documents and viewing documents.</p> <p>Conclusions</p> <p>Our approach solves the consent issue when using IHE profiles for regional health information networks. It is highly interoperable due to the use of international standards and can hence be used in any other region to leverage consent issues and substantially promote the use of IHE for regional health information networks in general.</p

Designing and Building immersive education spaces using Project Wonderland: from pedagogy through to practice

This paper presents work on the JISC funded SIMiLLE project to build a culturally sensitive virtual world to support language learning. This builds on the MiRTLE project (funded by Sun Microsystems), which created a mixed-reality space for teaching and learning. The aim of the SIMiLLE project is to investigate the technical feasibility and pedagogical value of using virtual environments to provide a realistic socio-cultural setting and content for language learning interaction. The paper starts by providing some background information on the Wonderland platform and the MiRTLE project, and then outlines the requirements for SIMiLLE, and how these requirements will be supported through the use of a virtual world based on Project Wonderland. We then present our plans for the evaluation of the system, with a particular focus on the importance of incorporating pedagogy into the design of these systems, and how we can support good practice with the ever-growing use of 3D virtual environments in formalised education

Wikis supporting authentic, collaborative activities: lessons in usability

The Open University delivers distance learning to its students. Traditionally, its students work independently of each other. Looking to enhance their students learning, two postgraduate courses have introduced authentic, collaborative activities. This is easier to achieve now because of the availability of wikis: a lightweight, web-based collaborative authoring environment. This paper examines the effect of the wikis’ functionality on the students’ use of the tool, and the consequences for the students’ engagement with the activities and learning opportunities. This is a relatively large scale study involving 56 wikis produced by over 250 students. The data was drawn from the two courses using a variety of methods. A qualitative inductive analysis was used to look for emergent themes. These were validated by cross referencing, to match recorded comments with wiki content. We found that the limited functionality of wikis influenced how students engaged with the collaborative activities. While all groups were able to collaboratively author the documents required for assessment, they were not always produced in the way intended by the course teams. This meant the expected benefits of collaborative learning were not always realised. This paper will be of interest to academics aspiring to employ wikis on their courses and to practitioners who wish to realise the potential of wikis in facilitating information sharing and fostering collaboration within teams

Simplified Single Source Xml Model: for Student-Centered Educational Content Management

This study investigates XML as a single source, recommending solutions and defining future needs for educators to manage student-centered educational content for diverse user preferences and multi-modal delivery. This research proposes a simplified XML single source model for educational course content management and XSL transformation of course material into multi-modal display/output that enables student-centered learning. The reviewed literature exposed four problem areas related to content management in which an XML single source might be a solution. Reviewed and synthesized literature related to XML into a cubed relationship with opposing the sides of the cube (content management/single source, corporate goals/educational goals and reuse/re-purpose) compared and contrasted. The result points to the need for a simplified XML model in order to realize the potential of educational goals for student-centered transformations (re-purposing content) and to future proof content management that is device independent and provides possible solutions to the problem areas in content management and technology management of course material
