Post-mortem biochemical investigations of vitreous humor

For several decades vitreous humor has been used for post-mortem biochemical investigations with the objective of a post-mortem diagnosis of pre-existing diseases and the clarification of forensic issues, in particular the determination of the post-mortem interval. For the determination of measured concentrations in vitreous humor pre-analytic factors as well as analytical and instrumental variations have to be taken into consideration. The aim of this study was a methodical investigation of two methods of sample pre-treatment as influencing variables. The compared methods were centrifugation and treatment in the ultrasonic bath. The determined parameters were sodium, potassium, chloride, calcium, lactate, urea, glucose and creatinine. Analyses were performed photometrically or by an ion-selective electrode. For some of the analytes a dilution was necessary before analysing. Regarding to the two pre-treatment methods, significant differences in the measured concentrations were not found. The precision proved to be mostly unsatisfying and was clearly better in diluted samples than in undiluted aliquots. A comparison of the vitreous humor of the two ocular bulbs did not lead to significant differences.     

Institutional Collective Action and Economic Development Joint Ventures

There is high interest in economic development efforts involving cooperation or collaboration among metropolitan jurisdictions. To determine why some local governments engage in cooperative agreements while others do not, this paper investigates transaction obstacles, including bargaining, information, agency, enforcement, and division problems. The authors then advance an institutional collective action explanation for intergovernmental cooperation, focusing on the conditions under which these transactions costs are low. This work anticipates that the costs associated with interlocal cooperation are influenced by the demographic characteristics of communities, local political institutions, and the nature of regional government networks. Empirical analysis based on a national survey of local development officials provides support for several predictions from this model and identifies policy variables that, in turn, increase the prospects for cooperation, specifically through the development of informal policy networks.     

Crossing the Ideological Divide? Egypt's Salafists and the Muslim Brotherhood after the Arab Spring

An important strand in the literature has stressed the analytical distinction between the Muslim Brotherhood's brand of Islamism and the Salafist movement. This article examines the shifts that have occurred within these two movements in Egypt since the Arab Spring. It specifically asks whether approximations between them in terms of strategies of actions have been paralleled by ideological approximations. The article argues that both movements have seen increased diversification which has—especially at the fringes—involved a reshaping of identities and ideological approximations that may facilitate cooperation between segments of these movements in the future.     

Talking Cop: Discourses of Change and Policing Identities

This paper presents empirical and theoretical analysis of the enactment of New Public Management (NPM) within the UK police service. It draws on empirical material gathered in a two-year study that explores the ways in which individual policing professionals have responded to, and received, the NPM discourse. Theoretically informed by a discursive approach to organizational analysis, the paper focuses on the new subject positions promoted within NPM that serve to challenge traditional understandings of policing organization and identities. The paper examines the implications of this for policies that promote community orientated policing (COP) and increased inter-agency partnership. The paper argues that the promotion of a more progressive form of policing, based on community orientation and equality principles, may struggle to gain legitimacy within the current performance regime that legitimizes a competitive masculine subjectivity, with its emphasis on crime fighting.     

Social Service Provision in the US and Germany: Convergence or Path Dependency?

With a special focus on social services, the article discusses the topic of convergence versus path dependency of state welfare arrangements in the US and Germany. In both countries, social services cover a broad spectrum of activities. In the US as well as in Germany, these services are to a large extent provided by non-profit organisations, although the two countries belong to very different welfare regimes. With a special eye on social services, the article provides an overview of the history of the two welfare states; it refers to current developments, of which the shift towards private commercial social service provision is most prominent. Against this background, the article comes to the conclusion that there is no simple answer to the question of path-dependency versus convergence. Indeed, in both countries commercial provision of social services is on the increase; however, current developments in Germany and the US do not reflect thoroughly the path-dependent or the convergence approach of depicting change.
