The role of the greens in the local politics of West Germany.

The study examines the contribution of the Greens to the changing nature of West Germany's local politics in the 1980s. The changes correspond broadly to the politicisation and parliamentarisation of a sphere of government traditionally perceived as being "unpolitical". Building upon theories of the New Politics, it is suggested that the varying pace of socio-economic change across the Federal Republic underlies the nonuniform development of its local party systems. The party systems of localities which have witnessed rapid social and economic change are found to be more susceptible to the emergence of a New Politics dimension than those of communities in which change has occurred less rapidly. The thesis continues by addressing aspects of the Greens' role in the development of local party systems across the Federal Republic. Despite the fact that marked differences in the Greens' approach to local political participation are registered in communities of varying socio-economic types, it is argued that the Greens are largely responsible for the introduction of a "New Local Politics" dimension into West Germany's local party systems. In a comprehensive study of the Greens' role in the Mainz party system, the conflicting styles and practices of the Greens and the established political parties in the city are depicted. The failure of the Green Party to form an alliance with the SPD in the city council is attributed to the cleavage between the Greens' New Politics and the SPD's Old Politics approaches. A detailed analysis of the parliamentary initiatives introduced by the four parties represented in the Mainz council between 1984 and 1987 also supports the contention that a New Politics dimension exists in the city's party system. This dimension is identified as representing a significant source of conflict during the period of analysis.

Cryptographic techniques for personal communication systems security

The advent of personal communication systems within the last decade has depended upon the utilization of advanced digital schemes for source and channel coding and for modulation. The inherent digital nature of the communications processing has allowed the convenient incorporation of cryptographic techniques to implement security in these communications systems. There are various security requirements, of both the service provider and the mobile subscriber, which may be provided for in a personal communications system. Such security provisions include the privacy of user data, the authentication of communicating parties, the provision for data integrity, and the provision for both location confidentiality and party anonymity. This thesis is concerned with an investigation of the private-key and public-key cryptographic techniques pertinent to the security requirements of personal communication systems and an analysis of the security provisions of Second-Generation personal communication systems is presented. Particular attention has been paid to the properties of the cryptographic protocols which have been employed in current Second-Generation systems. It has been found that certain security-related protocols implemented in the Second-Generation systems have specific weaknesses. A theoretical evaluation of these protocols has been performed using formal analysis techniques and certain assumptions made during the development of the systems are shown to contribute to the security weaknesses. Various attack scenarios which exploit these protocol weaknesses are presented. The Fiat-Sharmir zero-knowledge cryptosystem is presented as an example of how asymmetric algorithm cryptography may be employed as part of an improved security solution. Various modifications to this cryptosystem have been evaluated and their critical parameters are shown to be capable of being optimized to suit a particular applications. The implementation of such a system using current smart card technology has been evaluated.

The role of third party logistics providers (3PLs) in the adoption of green supply chain initiatives

The increasing importance of environmental sustainability has sharpened the focus on the need for innovative approaches to the purchasing of transport and logistics services. This article points out some of the challenges that purchasers of transport and logistics services, as well as their suppliers in the third party logistics (3PL) industry, are facing. These include the need for closer collaboration between 3PLs and their customers, as well as developing systems for the robust assessment of the environmental sustainability of services. The article is based on several years’ research experience in Ireland, Italy and Sweden.

Evaluating the use of IT by the third party logistics in South East Asia to achieve competitive advantage and its future trend

As the number of using 3PL providers are increasing rapidly in recent years, 3PL providers play a major role in the logistics industry. Due to customers demands are raising and changing, it has facilitated 3PL providers to invest IT systems that could meet customer requirements and create competitive advantage. The use of IT systems could assist 3PL providers to achieve supply chain visibility and enhance supply chain collaboration with business partners. In this paper, it is mainly focus on the Europe and Far East 3PL providers in terms of current and future IT systems, IT motivators and barriers, as well as the future supply chain demands that address by IT systems. The common IT system that implemented in both regions is information technology, which is mainly used to collaborate and share information with supply chain partners. Some of the common motivations and barriers were existed and 3PL providers need to be understood. Given the future demands of IT implementation and supply chain collaboration, IT systems such as RFID and integration systems would be strongly focus in the future. The suggestion about the advanced integration system such as business process management (BPM) could be the next key IT systems in the future logistics industry. © 2012 AICIT.
