The paper proposes addressing the design and implementation of a web‐based risk assessment system that enables remote project team members to assess the risks at the conceptual design stage.

The prototype system is based on a client/server architecture and uses fuzzy logic and web‐based technology. A risk assessment scenario is used to demonstrate the operation and benefits of the prototype system.

The research found that the use of a web‐based risk assessment system for distributed project team members has major benefits in terms of use of linguistic terms to express risk assessment, ease of communication, ease of maintenance, and greater consistency, among others.

There is scope for enhancing the system through the development of a risk management module, improving the user interface and making specific provisions for different project types.

The move in industry towards collaborative working practices is supported by systems such as this. Risk assessment is an important area that requires the input of all team members, if evenly distributed.

This paper has presented an innovative approach to risk assessment for distributed project teams. It will be of interest to all parties involved in construction projects, particularly those involved in risk assessment.

History shows that libraries have always functioned as physical portals to stored information. In the past, the physical library has consisted of reference and subject specific areas, card catalogs, and book stacks, all available during operating hours and confined to the library’s physical space within a building or room. However, with the explosive development of the Internet and the implementation of OPACs, libraries need to reinvent their environments as physical portals while establishing a virtual online portal presence. The Health Sciences Center Library at Stony Brook University has begun deploying several technologies to develop a virtual portal of online information and services, making the library and its resources available both inside and outside the confines of the physical library. The goal of this portal is two‐fold: provide the library’s patrons – particularly the students and faculty of the University’s Medical School – with personalized access to information, and to enable the library to gather statistics on the use of electronically‐based resources. What makes this library’s portal unique is its ability to deliver, over the Internet, desktop applications specific to certain academic programs in addition to traditional library resources, such as full‐text e‐journals and databases along with a Web‐based OPAC. The technology behind this portal incorporates centralized computing and client‐server architectures with recent thin‐client and operating system technologies, such as the Independent Computing Architecture, Windows 2000, and Linux. This portal demonstrates how academic libraries can improve individualized service by integrating existing systems of information delivery and retrieval with newer computing paradigms.

Improved integration, centralized databases, access through Web browsers and application service providers (ASPs) are some of the current trends impacting on organizational decisions regarding IS/IT outsourcing. Web‐based technology liberated the client/server IT model from the limits of geographical boundaries delimited by a local area network. Partnering with the right ASPs could provide organizations with the new synergy required for competitive advantage. This paper outlines the development of a “solutions” innovation business model of rental‐based sourcing, charters current ASPs and the differences in IS/IT provision and offers an audit of the benefits and costs of ASPs to businesses and other stakeholders. Future challenges are mapped out for consideration as are strategic choices associated with continued outsourcing, as distinct from in‐sourcing, of IS/IT.

This chapter focuses on learning space design for students’ technology-rich lifestyles, in particular the evolution and future of learning spaces in the United States. JISC design principles – bold, supportive, future proof, creative, and enterprising – frame discussion in the chapter’s first section, “Planning for the learning spaces of tomorrow.” The section begins with pioneering work in the field and follows with recent learning spaces (both classrooms and informal learning environments) that seek new and innovative ways for students to collaborate. Examples clearly point to students’ need for continual access to flexible, tech-rich spaces that support their work and study habits.

The chapter’s second section, “The future of learning spaces: On-demand apps and Bring Your Own Technology (BYOT),” is a case study focused on software virtualization’s influence on learning space design at Indiana University. The section brings in examples from the University of South Florida and the University of Iowa, asserting that physical and virtual learning spaces must be designed to come together seamlessly, echoing students’ on-the-go lifestyles and constant connectedness. Ultimately, the section makes a bold contention about the evolution of learning spaces: Any space can become a tech-rich learning environment, if students have access to virtualized software.

Throughout, the chapter touches on compelling questions about meeting the learning needs of digital natives: How do we challenge traditional educational paradigms? Can we flip the classroom to further the potential of all learners? What is the role of collaboration in learning? Which models will energize and inspire learners and instructors of the future?

Streaming audio/video contents over the Internet requires large network bandwidth and timely delivery of media data. A streaming session is generally long and also needs a large I/O bandwidth at the streaming server. A streaming server, however, has limited network and I/O bandwidth. For this reason, a streaming server alone cannot scale a streaming service well. An entire audio/video media file often cannot be cached due to intellectual property right concerns of the content owners, security reasons, and also due to its large size. This makes a streaming service hard to scale using conventional proxy servers. Media file compression using variable‐bit‐rate (VBR) encoding is necessary to get constant quality video playback although it produces traffic bursts. Traffic bursts either waste network bandwidth or cause hiccups in the playback. Large network latency and jitter also cause long start‐up delay and unwanted pauses in the playback, respectively. In this paper, we propose a proxy based constant‐bit‐rate (CBR)‐transmission scheme for VBR‐encoded videos and a scalable streaming scheme that uses a CBRtransmission scheme to stream stored videos over the Internet. Our CBR‐streaming scheme allows a server to transmit a VBRencoded video at a constant bit rate, close to its mean encoding bit rate, and deals with the network latency and jitter issues efficiently in order to provide quick and hiccup free playback without caching an entire media file. Our scalable streaming scheme also allows many clients to share a server stream. We use prefix buffers at the proxy to cache the prefixes of popular videos, to minimize the start‐up delay and to enable near mean bit rate streaming from the server as well as from the proxy. We use smoothing buffers at the proxy not only to eliminate jitter and traffic burst effects but also to enable many clients to share the same server stream. We present simulation results to demonstrate the effectiveness of our streaming scheme.

The Wales Institute of Social and Economic Research, Data and Methods (WISERD) is a major new collaborative socio‐economic research programme involving five higher education institutions in Wales. This paper introduces the work of the WISERD data integration team and describes their plans for the development of an online geo‐portal. Their aim is to support WISERD researchers by providing a framework for integrating, managing and disseminating quantitative and qualitative socio‐economic data in Wales. This paper outlines the goals of this major project, discusses the concept of the WISERD geo‐portal and reports on initial investigations into geo‐portal development using free and open‐source (FOSS) software. The paper concludes with a brief summary of the future work of the WISERD data integration team.

This paper presents DocML, a Web‐based digital library of university data. The goal is to build a system capable of preserving and managing student assignments efficiently in a university environment. It is based on a three‐tier architecture that is typical for distributed Web applications. Communication between the layers of the digital library and the architectural components that reside in the middle layer is facilitated through an XML standard. XML is also used for the development of a distributed metadata management system that describes the location and content of the digital library’s documents.

This paper seeks to redress the imbalance between technology and information by first examining three models of Knowledge Management with reference to the law firm context. Secondly, it examines the relationship that exists between the harnessing of corporate knowledge and the overall goals of a law firm, and in particular law firm profitability. Finally, given the existence of this relationship, it provides some signposts for the development of a Law Firm Knowledge Management Strategy.
