With the EU-enlargement process well underway, this paper focuses on social citizenship as a conceptual frame for analyzing the restructuring of social institutions in applicant countries in East Central Europe. So far, comparative welfare state analysis has concentrated mainly on the developed economies of the OECD-countries; there is little systematic analytical work on the transitions in post-communist Europe. Theoretically, this paper builds on comparative welfare state analysis as well as on new institutionalism. The initial hypothesis is built on the assumption that emerging patterns of social support and social security diverge from the typology described in the comparative welfare state literature inasmuch as the transformation of postcommunist societies is distinctly different from the building of welfare states in Europe. The paper argues that institutionbuilding is shaped by and embedded in the process of European integration and part of governance in the EU. Anticipating full membership in the European Union, the applicant countries have to adapt to the rules and regulations of the EU, including the "social acquis." Therefore, framing becomes an important feature of institutional changes. The paper seeks to identify distinct patterns and problems of the institutionalization of social citizenship.

Despite experimental evidences, the contributions of the concrete slab and composite action to the vertical shear strength of simply supported steel-concrete composite beams are not considered in current design codes, which lead to conservative designs. In this paper, the finite element method is used to investigate the flexural and shear strengths of simply supported composite beams under combined bending and shear. A three-dimensional finite element model has been developed to account for geometric and material nonlinear behavior of composite beams, and verified by experimental results. The verified finite element model is than employed to quantify the contributions of the concrete slab and composite action to the moment and shear capacities of composite beams. The effect of the degree of shear connection on the vertical shear strength of deep composite beams loaded in shear is studied. Design models for vertical shear strength including contributions from the concrete slab and composite action and for the ultimate moment-shear interaction ate proposed for the design of simply supported composite beams in combined bending and shear. The proposed design models provide a consistent and economical design procedure for simply supported composite beams.

In this Thesis, details of a proposed method for the elastic-plastic failure load analysis of complete building structures are given. In order to handle the problem, a computer programme in Atlas Autocode is produced. The structures consist of a number of parallel shear walls and intermediate frames connected by floor slabs. The results of an experimental investigation are given to verify the theoretical results and to demonstrate various factors that may influence the behaviour of these structures. Large full scale practical structures are also analysed by the proposed method and suggestions are made for achieving design economy as well as for extending research in various aspects of this field. The existing programme for elastic-plastic analysis of large frames is modified to allow for the effect of composite action of structural members, i.e. reinforced concrete floor slabs and the supporting steel beams. This modified programme is used to analyse some framed type structures with composite action as well as those which incorporate plates and shear walls. The results obtained are studied to ascertain the influence of composite action and other factors on the load carrying capacity of both bare frames and complete building structures. The theoretical failure load presented in this thesis does not predict the overall failure load of the structure nor does it predict the partial failure load of the shear walls and slabs but it merely predicts the partial failure load of a single frame and assumes that the loss of stiffess of such a frame renders the overall structure unusable. For most structures the analysis proposed in this thesis is likely to break down prematurely due to the failure of the slab and shear wall system and this factor must be taken into account in any future work on such structures. The experimental work reported in this thesis is acknowledged to be unsatisfactory as a verification of the limited theory proposed. In particular perspex was not found to be a suitable material for testing at high loads, micro-concrete may be more suitable.

Gas suppliers including Russia are facing the gas market uncertainty caused by the fast growing development of shale gas and liquefied natural gas (LNG). Given that Russia is one of the key energy suppliers in the world, Russian energy policy is intensively studied. However, the majority of the researches focus on the conventional gas sector and very few focus on the unconventional gas sector such as shale gas and LNG. In this light, this thesis aims at examining how the gas market uncertainty is framed in Russian gas export policy as well as discover how the interaction between underlying ideas and the policy frames informs policymaking. After analyzing Russian official documents, three policy frames were identified: shale gas—competition frame, LNG—cooperation frame and cooperation—competition frame. The shale gas—competition frame emphasizes the confrontation with the shale revolution in the USA. The LNG—cooperation frame rests on the idea of building cooperation with the Asia-Pacific region by the LNG trade. The cooperation—competition frame describes the oscillating Russia-EU relationship. Both the economic and ecological dimensions in the policy environment enable these three policy frames. However, the cooperation frame is constrained by the physical dimension since Russia has only one LNG facility in use. The institutional dimension underpins the idea of competition in the cooperation—competition frame. The reason is because of the divergent perspectives between Russia and the EU regarding regulations and market liberalizations. In sum, the result is different from the traditional geopolitical frame which depicts Russia as an energy superpower. Instead, this thesis suggests that Russia is shifting the priority from political interests to business interests in Russian gas export policy, particularly in the domain of shale gas and LNG.
