Supporting collaborative information retrieval in the virtual library

The advent of the virtual library is usually presented as a welcome development for library users. Unfortunately, this tends to reinforce the perception of the use of information resources as a solitary activity. In fact, as many studies have emphasised, information retrieval (IR) in the conventional library is often a highly collaborative activity, involving users' peers and experts such as librarians. Failure to take this into account in the design of virtual library services may result in its users being disadvantaged and denied timely and effective access to sources of assistance. Our focus here is on collaboration between users and librarians. We report an investigation of collaboration issues as seen from the perspective of librarians' and users' contexts and encapsulated in the notion of genre. Finally, we describe the design of a pilot multimedia-based system intended to support collaboration between librarians and IR system users

Virtuality in human supervisory control: Assessing the effects of psychological and social remoteness

Virtuality would seem to offer certain advantages for human supervisory control. First, it could provide a physical analogue of the 'real world' environment. Second, it does not require control room engineers to be in the same place as each other. In order to investigate these issues, a low-fidelity simulation of an energy distribution network was developed. The main aims of the research were to assess some of the psychological concerns associated with virtual environments. First, it may result in the social isolation of the people, and it may have dramatic effects upon the nature of the work. Second, a direct physical correspondence with the 'real world' may not best support human supervisory control activities. Experimental teams were asked to control an energy distribution network. Measures of team performance, group identity and core job characteristics were taken. In general terms, the results showed that teams working in the same location performed better than team who were remote from one another

Optimal Portfolio Management in Alaska: A Case Study on Risk Characteristics of Environmental Consulting Companies

A Project Submitted in Partial Fulfillment of the Requirements for the Degree of MASTER OF SCIENCE in Project ManagementSharp declines in global oil prices have led to a marked contraction in Alaska’s natural resource dependent economy. This, coupled with record the State’s budgetary shortfalls and a decrease in incoming federal dollars, has created a climate where environmental consulting companies must accept riskier projects to balance portfolio growth and security. As a result, companies must adopt a risk-based portfolio management approach as both a high level strategy and a core management practice. It is important to specifically identify projects best suited for an organization’s tolerance for risk based off of the supply and demand of the industry in rapidly changing economic conditions. Therefore, the aims of this project report are to help environmental consulting companies identify risk characteristics and manage their portfolio, as well as develop a tool to guide decision-making and selecting projects best suited for a companies’ portfolio strategy. The results of this research may provide Alaska based environmental companies with a clear understanding of the types of projects that offer both development and financial security for an organization. This research paper will present the methodology, results, and an environmental consulting portfolio management tool.Title Page / Table of Contents / List of Exhibits / Abstract / Introduction / Background / Literature Review / Project Methodology / Research Methodology / Presentation and Analysis of Data from Survey / Data Validation From Survey / Conclusion / Recommendation / Project Conclusion / Recommendations for Further Research / References / Appendi

Innovation in services : the contribution of design theory

Research in economics clearly points out that our economy is increasingly dependent on services but, paradoxically, the literature on innovation remains oriented toward product. Therefore many firms lacks well-tested methods to develop new services and rely on informal and largely haphazard processes. The paper makes use the recent advances in design theory to propose an integrated model of New Service Development. It illustrates how the identification of six design parameters of a new service (target clientele, support product, contract, front et back-office processes, economic model) helps clarifying the working of NSD processes. Further the paper assigns four different uses of the model as a NSD management tool.Services;Télématique automobile;Théorie de la conception;Gestion de l'innovation

Software development performance in remote student teams in international computer science collaboration

Approximately two-thirds of software projects are late because project teams encounter challenges that threaten their success. In addition, many projects are developed using remote collaboration, due to pressure of time, distribution of expertise, and organisational constraints. In parallel, technology has developed that allows effective remote collaboration.The purpose of this research was to investigate what characterises high performance in software development in remote student teams. The data was drawn from the Runestone Project, which involved Swedish and American computer science students in international collaboration on a substantial software development project. Runestone gave students the opportunity to use different technologies for collaboration across time and distance, as well the chance to develop problem-solving experience with different cultures in a team-based environment.This research tracked the progress and changes in the entire electronic communication for 8 student teams identified as the 4 highest- and lowest- 4 performers in the 2000 presentation of Runestone. A set of categories was developed to characterise over 31,000 lines of communication, focusing on the amount and nature of communication for each team, and on decision-making patterns throughout the software development process. The research also looked at students' use of available communication technology.Results indicate that both communication and the process and timing of specific actions are crucial to a team's success. Teams communicated differently, with high performing groups communicating less. High performing teams were more organised in the way they conducted their meetings and work. The management of the software development process as a whole was crucial, as was leadership style. An effective use of the software development process can also mean that key decisions are made during the times in the software process where they will be most effective. This research has implications for remote collaboration in both education and industry

Process Models and Distribution of Work in Offshoring Application Software Development

Common process models for the development of application software (AS) are examined as to how well they are suited for offshoring projects. The need for communication and interaction among onsite and offshore project stakeholders is identified as a critical success factor. Process models used by organizations providing offshoring services are discussed, and a generalized offshoring life cycle model is developed. A specific focus is set on the distribution of work between the organization that outsources AS development and the offshore organization that carries out the major share of the development work. Problems and challenges that have to be faced, making offshoring a difficult task, are discussed. --
