Firms invest in a variety of information technologies and seek to align their IT asset portfolios with two key performance outcomes: efficiency and innovation. Existing research makes the universalistic assumption that both outcomes will always be realized through firms’ IT asset portfolios. There has been limited research on the conditions under which firms’ IT asset portfolios should be orien...

In 1990, Miller wrote that no tools were available for assessment of what a learner does when functioning independently at the clinical workplace (Miller 1990 ). Since then portfolios have filled this gap and found their way into medical education, not only as tools for assessment of performance in the workplace, but also as tools to stimulate learning from experience. We give an overview of th...

This paper proposes the novel concept of Autonomous Restructuring Portfolios which would enable financial portfolios to re-adjust themselves to cater with the highly volatile customer behavior pattern. It investigates the possibility of using Kohonen’s Self Organizing Maps in analyzing, categorizing & modifying strategies applied on financial portfolios according to the its behavior patterns. I...

How influential is the president’s advantage in cabinet formation in presidential systems? Do presidents receive more and the most important portfolios? What factors lead to a more or less disproportionate distributions of portfolios? In this study, I suggest answers for these questions through a theory in which the disproportional allocation of portfolios can be explained by the privileged pos...

Multimedia conferencing over multiple Local Area Networks (LAN), or across a Wide Area Network requires the use of efficient multicast servers in order to function correctly. This paper presents a proposed Multiple LAN Internet Protocol Converter (MLIC) algorithm currently being implemented by the Network Research Group and Multimedia Research Labs Sdn. Bhd. for use with multimedia conferencing...

The purpose of this paper is to address the simultaneous management of multiple business relationships and multiple projects in the marketing strategy of the project-based firm. The research question is: How can the essence and interdependencies between the portfolios of relationships and projects be conceptualized as the marketing strategy of a project-based firm? We address this question by c...

This paper explores the potential diversification benefits of socially responsible investments for conventional stock portfolios by examining the risk spillovers and dynamic correlations between conventional and sustainability stock indexes from a number of regions. We observe significant unidirectional volatility transmissions from conventional to sustainable equities, suggesting that the crit...

Advances in network technology and research in real-time packet-switched networks have prompted the emergence of internet conferencing. While audio and video conferencing tools are readily available, shared workspaces and drawing tools have been slower to emerge. We present a design for a network conferencing whiteboard that differs in notable respects from other shared workspace prototypes. We...

In this paper we survey the conferencing architectures in H.323 and SIP. We give a compact review of the H.323 framework and capture the current status of the emerging SIP conferencing architecture. Subsequently we present a qualitative comparison of the schemes under study. The evaluation criteria are scalability to large conference sizes and to large geographical dispersion of participants ,a...

In the light of the increasing interest in efficient algorithms for solving abstract argumentation problems and the pervasive availability of multicore machines, a natural research issue is to combine existing argumentation solvers into parallel portfolios. In this work, we introduce six methodologies for the automatic configuration of parallel portfolios of argumentation solvers for enumeratin...
