Staircase Models from Affine Toda Field Theory

We propose a class of purely elastic scattering theories generalising the staircase model of Al. B. Zamolodchikov, based on the affine Toda field theories for simply-laced Lie algebras g=A,D,E at suitable complex values of their coupling constants. Considering their Thermodynamic Bethe Ansatz equations, we give analytic arguments in support of a conjectured renormalisation group flow visiting the neighbourhood of each W_g minimal model in turn.Comment: 22 pages, Saclay-Bologna preprint SPhT/92-065, DFUB-92-0

A strategic framework for e-government adoption in public sector organisations

E-government has been recognized as a change agent for public sector reform. Through this change, the public sector organisation plans to increase operating efficiencies, build information-sharing partnerships and improve communication with other organisations, as well as with the public. Several studies have discussed how e-government will transform public sector organisations from traditional paper-based systems to electronic delivery that leads self-service operations that develop efficiently managed internal business process. However, a number of voids exist in the immature e-government literature, regarding its adoption strategy and process. This paper looks at the implementation aspect of e-government in public sector organisations. The paper critically reviews the issues of e-government adoption and identifies factors that affect the implementation process, such as, technical, organisational, and environmental. In addition, the authors discuss the benefits and barriers that might influence the decision making process toward the adoption of e-government in public sector. Since, e-government is an emerging research area, there is limited literature explaining the framework of e-government adoption. Therefore, this study suggests a strategic framework for e-government adoption that will assist decision makers in public sector organisations to support their egovernment adoption strategy and guide the IT developers for implementation process of e-government project

Virtual R&D teams in small and medium enterprises: a literature review

Small and medium enterprises (SMEs) are the driving engine behind economic growth. While SMEs play a critical role in generating employment and supporting trade, they face numerous challenges, the prominent among them are the need to respond to fasting time-to-market, low-cost and rapid solutions to complex organizational problems. Towards that end, research and development (R & D) aspect deserves particular attention to promote and facilitate the operations of SMEs. Virtual R & D team could be a viable option. However, literature shows that virtual R & D teaming in SMEs is still at its infancy. This article provides a comprehensive literature review on different aspects of virtual R & D teams collected from the reputed publications. The purpose of the state-of-the-art literature review is to provide an overview on the structure and dynamics of R & D collaboration in SMEs. Specifying the foundation and importance of virtual teams, the relationship between virtual R & D team and SMEs has been examined. It concludes with the identification of the gaps in the existing literature's and calls for future research. It is argued that setting-up an infrastructure for virtual R & D team in SMEs still requires a large amount of engineering efforts and deserves consideration at top level management

Virtual teams for new product development: an innovative experience for R&D engineers

New interaction tools such as internet allow companies to gain valuable input from research and development (R\&D) engineers via virtual teams. Consequently, engineers also get more expertise in diminutive time frames. Virtual R\&D teams present the key impetus to the technology acquisition process. The present knowledge-economy era is characterized by short product life-cycles. Virtual R&D teams may reduce time-to-market, make available a large pool of new product know-how and provide greater flexibilities, which are the key success factors in a competitive market. This comprehensive review contains almost 100 references and covers the recent literature with emphasis on the topic. The review has focused on authentic and reputed publications and extracts the results. This article presents the type of virtual teams and their main features and explains how virtual R&D team can play a prominent role in developing new products. The article is evolved future study guideline and also illustrates how to apply virtual interaction tools and integrate engineers into the innovation process. Management of virtual R&D teams in new product development (NPD) processes in an innovative, effective and efficient is of a high importance, but the issue has been poorly addressed in the previous studies. Findings show that virtual R&D team provides valuable input for new product development and R&D engineers are able to attain virtual experience
