The politics of the new Germany

The Politics of the New Germany takes a new approach to understanding politics in the post-unification Federal Republic. Assuming only elementary knowledge, it focuses on debates and issues in order to help students understand both the workings of Germany's key institutions and some of the key policy challenges facing German politicians. Written in a straightforward style by four experts, each of the chapters draws on a rich variety of real-world examples. Packed with boxed summaries of key points, a guide to further reading and a range of seminar questions for discussion at the end of each chapter, this book highlights both the challenges and opportunities facing policy-makers in such areas as foreign affairs, economic policy, immigration, identity politics and institutional reforms. The book also takes a bird's-eye view of the big debates that define German politics over time, regardless of which party happens to be in power. It pinpoints three key themes that have characterised German politics over the last sixty years; reconciliation, consensus and transformation. Table of Contents: Introduction 1.

Group diversity and group identification:the moderating role of diversity beliefs

Research on diversity in teams and organizations has revealed ambiguous results regarding the effects of group composition on workgroup performance. The categorization—elaboration model (van Knippenberg et al., 2004) accounts for this variety and proposes two different underlying processes. On the one hand diversity may bring about intergroup bias which leads to less group identification, which in turn is followed by more conflict and decreased workgroup performance. On the other hand, the information processing approach proposes positive effects of diversity because of a more elaborate processing of information brought about by a wider pool and variety of perspectives in more diverse groups. We propose that the former process is contingent on individual team members' beliefs that diversity is good or bad for achieving the team's aims. We predict that the relationship between subjective diversity and identification is more positive in ethnically diverse project teams when group members hold beliefs that are pro-diversity. Results of two longitudinal studies involving postgraduate students working in project teams confirm this hypothesis. Analyses further reveal that group identification is positively related to students' desire to stay in their groups and to their information elaboration. Finally, we found evidence for the expected moderated mediation model with indirect effects of subjective diversity on elaboration and the desire to stay, mediated through group identification, moderated by diversity beliefs.

A dynamic model of the hypoxia-inducible factor 1α (HIF-1α) network

Activation of the hypoxia-inducible factor (HIF) pathway is a critical step in the transcriptional response to hypoxia. Although many of the key proteins involved have been characterised, the dynamics of their interactions in generating this response remain unclear. In the present study, we have generated a comprehensive mathematical model of the HIF-1a pathway based on core validated components and dynamic experimental data, and confirm the previously described connections within the predicted network topology. Our model confirms previous work demonstrating that the steps leading to optimal HIF-1a transcriptional activity require sequential inhibition of both prolyl- and asparaginyl-hydroxylases. We predict from our model (and confirm experimentally) that there is residual activity of the asparaginyl-hydroxylase FIH (factor inhibiting HIF) at low oxygen tension. Furthermore, silencing FIH under conditions where prolyl-hydroxylases are inhibited results in increased HIF-1a transcriptional activity, but paradoxically decreases HIF-1a stability. Using a core module of the HIF network and mathematical proof supported by experimental data, we propose that asparaginyl hydroxylation confers a degree of resistance upon HIF-1a to proteosomal degradation. Thus, through in vitro experimental data and in silico predictions, we provide a comprehensive model of the dynamic regulation of HIF-1a transcriptional activity by hydroxylases and use its predictive and adaptive properties to explain counter-intuitive biological observations.

Contrast sensitivity improves after brimonidine therapy in primary open angle glaucoma:a case for neuroprotection

Aims: To determine the visual outcome following initiation of brimonidine therapy in glaucoma. Methods: 16 newly diagnosed previously untreated glaucoma patients were randomly assigned to either timalal 0.5% or brimanidine 0.2%. Visual acuity, contrast sensitivity (CS), visual fields, intraocular pressure (IOP), blaad pressure, and heart rate were evaluated at baseline and after 3 months. Results: IOP reduction was similar far both groups (p<0.05). Brimanidine improved CS; in the right eye at 6 and 12 cpd (p = 0.043, p = 0.017); in the left eye at 3 and 12 cpd (p = 0.044, p = 0.046). Timolol reduced CS at 18 cpd in the right eye (p = 0.041). There was no change in any other measured parameters. Conclusion: Glaucoma patients exhibit improved CS an initiation of brimanidine therapy.
