Between ideology and pragmatism: the politics of dual nationality in Germany

This article discusses the policy and politics of dual nationality in Germany. It contrasts the policy reality, in which dual nationality is tolerated in a wide range of cases, with Germany's continued opposition in principle to this phenomenon. It then analyzes political, cultural and electoral factors to explain why this opposition persists despite these widespread exceptions. In conclusion, the article argues that by continuing formally to oppose dual nationalities, Germany in effect discourages naturalizations and thereby continues to operate a broadly exclusive citizenship.

Is there a trade-off between quality and productivity? The case of diagnostic technologies in Portugal

The purpose of this paper is twofold: first, we compute quality-adjusted measures of productivity change for the three most important diagnostic technologies (i.e., the Computerised Tomography Scan, Electrocardiogram and Echocardiogram) in the major Portuguese hospitals. We use the Malmquist–Luenberger index, which allows to measure productivity growth while controlling for the quality of the production. Second, using non-parametric tests, we analyse whether the implementation of the Prospective Payment System may have had a positive impact on the movements of productivity over time. The results show that the PPS has helped hospitals to use these tools more efficiently and to improve their effectiveness.

The role of experts in policy making

As public policy issues increasingly have a technical aspect to them an interactive relationship has developed between science and policy. The aim of this thesis is to investigate the two aspects of this relationship: the influence of science on policy and the influence of policy implications on science. Most existing studies in this area treat only one or other of these aspects. Furthermore, they tend to provide interesting case study material but very little theoretical analysis. This thesis attempts to overcome these problems by dealing with both aspects of the interaction between science and policy and by providing theoretical models of this relationship. The thesis combines the theoretical development of these models with the analysis of three empirical case studies: the controversy in Britain over smoking and health; the application of educational psychology to the development of education policy in Britain; the controversy over the health effect of lead in the environment. The theoretical models are developed in Part 1. In Part 2 the empirical case studies are presented and in Part 3 the theoretical material is assessed in the light of these case studies. The main thesis of this study is that there is a fundamental mismatch between science and policy-making. Criticism is always essential in science. However, when science is involved in the policy process, either scientific claims are not subjected to a significant level of criticism or they are scrutinized so closely that no view achieves general consensus and conflicting advice results. In this situation, contrary to the traditional view, science can generate uncertainty. The role which science plays in the policy process is influenced by this level of criticism, by the context of political power and by the progress of an issue through the various stages of the policy process.

Understanding the link between transglutaminase and the induction of fibrosis in cystic fibrosis (CF)

The emerging role of the multifunctional enzyme, Transglutaminase 2 (TG2) in Cystic Fibrosis (CF) has been linked to its increased expression and intracellular transamidating activity. However, a full understanding of the molecular mechanisms involved still remains unclear despite numerous studies that have attempted to delineate this process. These mechanisms include the NFκB and TGFβ1 pathway amongst others. This study reveals for the first time that the development of fibrosis in CF is due to a TG2-driven epithelial to mesenchymal transition (EMT) via a mechanism involving the activation of the pro-fibrotic cytokine TGFβ1. Using a human ΔF508/W1282X CFTR CF mutant bronchial cell (IB3-1), its CFTR corrected “add-back” cell (C38) as well as a primary human bronchial epithelial cell (HBEC), elevated TG2 levels in the CFTR mutant IB3 cell were shown to activate latent TGFβ1 leading to increased levels found in the culture medium. This activation process was blocked by the presence of cell-permeable and impermeable TG2 inhibitors while inhibition of TGFβ1 receptors blocked TG2 expression. This demonstrates the direct link between TG2 and TGFβ1 in CF. The presence of active cell surface TG2 correlated with an increase in the expression of EMT markers, associated with the CF mutant cells, which could be blocked by the presence of TG2 inhibitors. This was mimicked using the “addback” C38 cell and the primary human bronchial epithelial cell, HBEC, where an increase in TG2 expression and activity in the presence of TGFβ1 concurred with a change in cell morphology and an elevation in EMT marker expression. Conversely, a knockdown of TG2 in the CF mutant IB3 cells illustrated that an inhibition of TG2 blocks the increase in EMT marker expression as well as causing an increase in TEER measurement. This together with an increase in the migration profile of the CF mutant IB3 cell against the “add-back” C38 cell suggests that TG2 drives a mesenchymal phenotype in CF. The involvement of TG2 activated TGFβ1 in CF was further demonstrated with an elevation/inhibition of p- SMAD 2 and 3 activation in the presence of TGFβ1/TG2 cell-permeable/impermeable inhibitors respectively. The use of a comparative airway cell model where bronchial epithelial cells were cultured at the air liquid interface (ALI) confirmed the observations in submerged culture depicting the robustness of the model and reiterated the importance of TG2 in CF. Using a CFTR corrector combined with TG2 inhibitors, this study showed that the correction and stabilisation of the ΔF508 CFTR mutation in the mutant cell forged an increase in matured CFTR copies trafficking to the apical surface by circumventing proteosomal degradation. Thus the results presented here suggests that TG2 expression is elevated in the CFTR mutant bronchial cell via a TGFβ1 driven positive feedback cycle whereby activation of latent TGFβ1 by TG2 leads in turn to an elevation in its own expression by TGFβ1. This vicious cycle then drives EMT in CF ultimately leading to lung remodelling and fibrosis. Importantly, TG2 inhibition blocks TGFβ1 activation leading to an inhibition of EMT and further blocks the emerging fibrosis, thus stabilizing and supporting the maturation, trafficking and conductance of CFTR channels at the apical surface.

Bioreaction and separation in preparative batch chromatographic columns : the hydrology of lactose to yield glucose,galactose and oligosaccharides

The initial aim of this project was to improve the performance of a chromatographic bioreactor-separator (CBRS). In such a system, a dilute enzyme solution is pumped continuously through a preparative chromatographic column, while pulses of substrate are periodically injected on to the column. Enzymic reaction and separation are therefore performed in a single unit operation. The chromatographic columns used were jacketed glass columns ranging from 1 to 2 metres long with an internal diameter of 1.5 cm. Linking these columns allowed 1, 2, 3 and 4 metre long CBRS systems to be constructed. The hydrolysis of lactose in the presence of β~galactosidase was the reaction of study. From previous work at Aston University, there appeared to be no difficulties in achieving complete lactose hydrolysis in a CBRS. There did, however, appear to be scope for improving the separative performance, so this was adopted as an initial goal. Reducing the particle size of the stationary phase was identified as a way of achieving this improvement. A cation exchange resin was selected which had an average particle size of around half that previously used when studying this reaction. A CBRS system was developed which overcame the operational problems (such as high pressure drop development) associated with use of such a particle size. A significant improvement in separative power was achieved. This was shown by an increase in the number of theoretical plates (N) from about 500 to about 3000 for a 2 metre long CBRS, coupled with higher resolution. A simple experiment with the 1 metre column showed that combined bioreaction and separation was achievable in this system. Having improved the separative performance of the system, the factors affecting enzymic reaction in a CBRS were investigated; including pulse volume and the degree of mixing between enzyme and substrate. The progress of reaction in a CBRS was then studied. This information was related to the interaction of reaction and separation over the reaction zone. The effect of injecting a pulse over a length of time as in CBRS operation was simulated by fed batch experiments. These experiments were performed in parallel with normal batch experiments where the substrate is mixed almost instantly with the enzyme. The batch experiments enabled samples to be taken every minute and revealed that reaction is very rapid. The hydrodynamic characteristics of the two injector configurations used in CBRS construction were studied using Magnetic Resonance Imaging, combined with hydrodynamic calculations. During the optimisation studies, galactooligosaccharides (GOS) were detected as intermediates in the hydrolysis process. GOS are valuable products with potential and existing applications in food manufacture (as nutraceuticals), medicine and drug targeting. The focus of the research was therefore turned to GOS production. A means of controlling reaction to arrest break down of GOS was required. Raising temperature was identified as a possible means of achieving this within a CBRS. Studies were undertaken to optimise the yield of oligosaccharides, culminating in the design, construction and evaluation of a Dithermal Chromatographic Bioreactor-separator.

Public opinion and the making of foreign policy in the 'New Europe':a comparative study of Poland and Ukraine

Since 1989, by drawing a new boundary between the EU and its eastern neighbours, the European Union has created a frontier that has been popularly described in the frontier states as the new 'Berlin Wall'. This book is the first comparative study of the impact of public opinion on the making of foreign policy in two eastern European states that live on either side of the new European divide: Poland and Ukraine. Focusing on the vocal, informed segment of public opinion and drawing on results of both opinion polls and a series of innovative focus groups gathered since the Orange Revolution, Nathaniel Copsey unravels the mystery of how this crucial segment of the public impacts on foreign policy-makers in both states. In developing this argument, Copsey takes a closer look at the business community and how important economic factors are in forming public opinion. Filling a gap in the literature currently available on the topic, this book presents a fresh approach to our understanding of Polish-Ukrainian relations and how the public's view of the past influences contemporary politics. It is an ideal resource for those researching in the field of Russian and Eastern European Studies.

The Ecumenical movement and the making of the European Community

The European Community has largely been considered a predominantly secular project, bringing together the economic and political realms, while failing to mobilise the public voice and imagination of churchmen and the faithful. Drawing on a wide range of archival sources, this is the first study to assess the political history of religious dialogue in the European Community. It challenges the widespread perception that churches started to engage with European institutions only after the 1979 elections to the European Parliament, by detailing close relations between churchmen and high-ranking officials in European institutions, immediately after the 1950 Schuman Declaration. Lucian N. Leustean demonstrates that Cold War divisions between East and West, and the very nature of the ecumenical movement, had a direct impact on the ways in which churches approached the European Community. He brings to light events and issues which have not previously been examined, such as the response of churches to the Schuman Plan, and the political mobilisation of church representations in Brussels, Strasbourg and Luxembourg. Leustean argues that the concept of a 'united Europe' has been impeded by competing national differences between religious and political institutions, having a long-standing legacy on the making of a fragmented European Community.

The politics of knowledge in central Asia:science between Marx and the market

Through careful historical and ethnographic research and extensive use of local scholarly works, this book provides a persuasive and careful analysis of the production of knowledge in Central Asia. The author demonstrates that classical theories of science and society are inadequate for understanding the science project in Central Asia. Instead, a critical understanding of local science is more appropriate. In the region, the professional and political ethos of Marxism-Leninism was incorporated into the logic of science on the periphery of the Soviet empire. This book reveals that science, organizes and constructed by Soviet rule, was also defined by individual efforts of local scientists. Their work to establish themselves 'between Marx and the market' is therefore creating new political economies of knowledge at the edge of the scientific world system.

Between safety and vulnerability:the exiled other of international relations

Inspired by the idea of safe citizenship this article queries the possibilities of safety in an age of securitization. It challenges the cosmopolitan worldview and its iteration of a global cosmopolitan citizen. It champions an account of affective citizenship, narration and attends to the trauma of exile. It offers an account of exile before suggesting an institutional design premised on politicization. This design, it is argued, facilitates moments of storytelling fostering individual empowerment. This unorthodox rendering of agency allows the traumatized exile to negotiate the world as it is, not as it could be, as a potential ‘safe’ citizen.

Minority dissent and team innovation:the importance of participation in decision making

This study integrates research on minority dissent and individual creativity, as well as team diversity and the quality of group decision making, with research on team participation in decision making. From these lines of research, it was proposed that minority dissent would predict innovation in teams but only when teams have high levels of participation in decision making. This hypothesis was tested in 2 studies, 1 involving a homogeneous sample of self-managed teams and 1 involving a heterogeneous sample of cross-functional teams. Study 1 suggested that a newly developed scale to measure minority dissent has discriminant validity. Both Study 1 and Study 2 showed more innovations under high rather than low levels of minority dissent but only when there was a high degree of participation in team decision making. It is concluded that minority dissent stimulates creativity and divergent thought, which, through participation, manifest as innovation.

'Between a rock and a hard place':towards a theorisation of the role of gender in junior management

This paper seeks to theorise the role that gender plays in the careers of junior female managers. We do this by drawing upon two separate empirical studies, firstly a largescale study based on interviews with female managers in the West Midlands (UK) is used to explore the growth of female participation in junior managerial roles with reference to the notion of managerial careers as seduction. We explore the routes the women have taken into junior management careers and the barriers that exist to progression toward more senior roles. Secondly, a small-scale ethnographic study of a large service-based organization, also based in the West Midlands, is documented in an attempt to theorise the organizational role of female junior managers. While the dominance of masculine values and practices in organisations is explored, we also argue that growing female participation at junior managerial levels can only partly be explained by female managers adopting, or appearing to adopt, masculine behaviours. We seek to contribute to a fuller explanation by drawing attention to the way in which senior managers in the case study sought to employ female junior managers particularly for their perceived feminine skills. Significantly, however the ethnography reveals the ambiguously gendered construction of female junior managers roles through an exploration of the enactment of both masculine and feminine practices during the ‘doing’ of management.
