Argues that globalism propelled by neoliberalism is an inherently destabilizing and criminogenic force. Although globalization creates a plethora of illicit opportunities and illegal motivations, it weakens control structures. Merton's concept of relative deprivation and anomie are becoming increasingly applicable to large swathes of the developing world. The disjunction between goals and means fuels the corruption, drug dealing, transnational prostitution and sexual slavery of shadow economies such as Russia's, as well as rioting, rebellion and other collective action.

Southern Europe suffers from forest fires. The management of these disasters is of importance to both government authorities and the public. This article presents the results of a research project aimed at modeling forest fire events and producing fire risk maps. The mathematical model is embedded in an ArcView Geographic Information System (GIS) platform. The interface is in Visual C++ 6.0. The thematic and individual risk maps generated are merged into an integrated risk map. The assessment platform (model, GIS, data, decision support) was applied to the area of northern Evia Island, central Greece, using five different scenarios. The platform provides a tool for use by authorities to estimate risks for forest fire management. The model was specifically adapted for the Olympic Games of 2004, Athens, Greece.

The medium access control (MAC) protocol and the underlying traffic scheduling algorithm developed within project Magic WAND (Wireless ATM Network Demonstrator) are presented. Magic WAND is investigating wireless ATM technology for customer premises networks in the framework of the Advanced Communications Technologies and Services (ACTS) program funded by the European Union. The MAC protocol, known as MASCARA, is a hub-based, adaptive TDMA scheme which combines reservation- and contention-based access methods to provide multiple access efficiency and quality-of-service guarantees to wireless ATM terminal connections sharing a common radio channel. The traffic scheduling algorithm is delay-oriented to meet the requirements of the various traffic classes defined by the ATM architecture. The results of the simulation of a number of scenarios are presented to assess the performance of the proposed algorithm.

The Medium Access Control (MAC) protocol defined in the Wireless ATM Network Demonstrator (WAND) system being developed within the project Magic WAND is presented. Magic WAND is investigating extensions of ATM technology to cover wireless customer premises networks, in the framework of the Advanced Communications Technologies and Services (ACTS) programme, funded by the European Union. The MAC protocol, known as MASCARA, uses a dynamic TDMA scheme, which combines reservation- and contention-based access methods to provide multiple access efficiency and quality of service guarantees to wireless ATM terminal connections sharing a common radio channel. The paper focuses on the description of PRADOS, a delay-oriented traffic scheduling algorithm, which aims at satisfying the requirements of the various traffic classes defined by the ATM architecture. Simulation results are presented to assess the performance of the proposed algorithm in scheduling transmission of variable bit rate connections.
