In recent years, the European Union has come to view cyber security, and in particular, cyber crime as one of the most relevant challenges to the completion of its Area of Freedom, Security and Justice. Given European societies’ increased reliance on borderless and decentralized information technologies, this sector of activity has been identified as an easy target for actors such as organised criminals, hacktivists or terrorist networks. Such analysis has been accompanied by EU calls to step up the fight against unlawful online activities, namely through increased cooperation among law enforcement authorities (both national and extra- communitarian), the approximation of legislations, and public- private partnerships. Although EU initiatives in this field have, so far, been characterized by a lack of interconnection and an integrated strategy, there has been, since the mid- 2000s, an attempt to develop a more cohesive and coordinated policy. An important part of this policy is connected to the activities of Europol, which have come to assume a central role in the coordination of intelligence gathering and analysis of cyber crime. The European Cybercrime Center (EC3), which will become operational within Europol in January 2013, is regarded, in particular, as a focal point of the EU’s fight against this phenomenon. Bearing this background in mind, the present article wishes to understand the role of Europol in the development of a European policy to counter the illegal use of the internet. The article proposes to reach this objective by analyzing, through the theoretical lenses of experimental governance, the evolution of this agency’s activities in the area of cyber crime and cyber security, its positioning as an expert in the field, and the consequences for the way this policy is currently developing and is expected to develop in the near future.

This thesis explores, in a team context, using the Michigan Model, the relationship between social support, stress and well-being outcomes. The studies reported were carried out in Post Office Ltd. Study one examines differences in social support source and type for employees working in teams and quasi teams. Analysis was carried out at the individual level. The results supported previous work on well-being in teams: individuals working in teams report significantly higher levels of well-being, job satisfaction and organisational commitment than those individuals in quasi teams. Members of teams reported greater satisfaction with support from their manager and colleagues, and all types of support compared to members of quasi teams. Manager support and specific types of support mediated the relationship between team working and well-being outcomes. In terms of stressors, satisfaction with manager support and emotional challenge predicted greater influence which was positively related to the well-being outcomes. Study two conducted at the team level builds on relationships established in study one. Stage one explored teamness, the extent to which, along a continuum the team was well-defined. Stage two explored teamness agreement, the extent to which the team agreed on their teamness. The extent to which the Branch Office were a well-defined team had a positive effect on team functioning; participation, innovation and commitment to task excellence. Team functioning was associated with higher levels of satisfaction with manager and team support and all types of support. Working in a well-defined team was associated with job satisfaction, mediated by positive team functioning and social support. Teamness agreement predicted team well-being, clarity of objectives, work demands and satisfaction with reality check. Working in a team was not associated with performance. This thesis advances understanding in the area of team working and processes within teams, advancing understanding of the specifics of social support from different so urces and types of support. The studies reveal the key role of team functional characteri stics in creating the vehicle through which supportive interactions take place. which contribute to positive outcomes associated with working in a well-defined team.

Previous work has indicated the presence of collapsing and structured soils in the surface layers underlying Sana's, the capital of Yemen Republic. This study set out initially to define and, ultimately, to alleviate the problem by investigating the deformation behaviour of these soils through both field and laboratory programmes. The field programme was carried out in Sana'a while the laboratory work consisted of two parts, an initial phase at Sana's University carried out in parallel with the field programme on natural and treated soils and the major phase at Aston University carried out on natural, destructured and selected treated soils. The initial phase of the laboratory programme included classification, permeability, and single (collapsing) and double oedometer tests while the major phase, at Aston, was extended to also include extensive single and double oedometer tests, Scanning Electron Microscopy and Energy Dispersive Spectrum analysis. The mechanical tests were carried out on natural and destructed samples at both the in situ and soaked moisture conditions. The engineering characteristics of the natural intact, field-treated and laboratory destructured soils are reported, including their collapsing potentials which show them to be weakly bonded with nil to severe collapsing susceptibility. Flooding had no beneficial effect, with limited to moderate improvement being achieved by preloading and roller compaction, while major benefits were achieved from deep compaction. From these results a comparison between the soil response to the different treatments and general field remarks were presented. Laboratory destructuring reduced the stiffness of the soils while their compressibility was increasing. Their collapsing and destructuring mechanisms have been examined by studying the changes in structure accompanying these phenomena. Based on the test results for the intact and the laboratory destructured soils, a simplified framework has been developed to represent the collapsing and deformation behaviour at both the partially saturated and soaked states, and comments are given on its general applicability and limitations. It has been used to evaluate all the locations subjected to field treatment. It provided satisfactory results for the deformation behaviour of the soils destructed by field treatment. Finally attention is drawn to the design considerations together with the recommendations for the selection of potential improvement techniques to be used for foundation construction on the particular soils of the Sana's region.
