Virtopsy: postmortem minimally invasive angiography using cross section techniques--implementation and preliminary results

Postmortem investigation is increasingly supported by Computed Tomography (CT) and Magnetic Resonance Imaging (MRI). This led to the idea to implement a noninvasive or minimally invasive autopsy technique. Therefore, a minimally invasive angiography technique becomes necessary, in order to support the vascular cross section diagnostic. Preliminary experiments investigating different contrast agents for CT and MRI and their postmortem applicability have been performed using an ex-vivo porcine coronary model. MSCT and MRI angiography was performed in the porcine model. Three human corpses were investigated using minimally invasive MSCT angiography. Via the right femoral artery a plastic tube was advanced into the aortic arch. Using a flow adjustable pump the radiopaque contrast agent meglumine-ioxithalamate was injected. Subsequent MSCT scanning provided an excellent anatomic visualization of the human arterial system including intracranial and coronary arteries. Vascular pathologies such as calcification, stenosis and injury were detected. Limitations of the introduced approach are cases of major vessel injury and cases that show an advanced stage of decay.     

Experimental tests for the validation of active numerical human models

The development of numerical human models is a topic of current interdisciplinary research. In the field of automotive safety these models can be applied for the optimization of protection systems. In forensic research human models can be used for the investigation of injury mechanisms and for the prediction and reproduction of injury patterns. However, up to now human models have been validated on the basis of PMHS tests without considering the effects of muscle activity. This paper shows two experimental volunteer test set-ups for the generation of experimental validation data. In a pendulum set-up the influence of muscle activity on the human kinematics was investigated. A drop test set-up was developed for the analysis of the effects of muscle activity on impact response characteristics of muscle tissue. Experimental results, presented in this paper, can be used for the validation and optimization of active numerical human models.     

Becoming an entrepreneurial university? A case study of knowledge exchange relationships and faculty attitudes in a medium-sized,research-oriented university

This paper seeks to contribute to the growing literature on the entrepreneurial university by mapping knowledge exchange relationships of entrepreneurial faculty in a comprehensive manner and also capturing faculty attitudes towards measures taken by the university administration to promote entrepreneurship. We report on an exploratory study of Sussex University, a medium-sized, research-oriented university, which launched technology transfer activities in the mid-1990s. Our results show that, in spite of a comparatively late start, a considerable number of researchers engage in knowledge exchange processes with industry and other non-academic partners. We present evidence that suggests faculty in the social sciences and humanities as well as natural sciences and engineering maintain links to industrial partners, including multinational corporations. Furthermore, our observations indicate that schools differ in the way their faculty engage in university–industry collaborations. Further differences can be observed with respect to faculty attitudes towards technology transfer and awareness of the university’s respective codes of practice.

Rechtssicherheit und Einzelfallgerechtigkeit im Wirtschaftsprivatrecht

Das Wirtschaftsprivatrecht ist von professionellen und planenden Akteuren beherrscht, die zur Minimierung der Transaktionskosten auf die weitestm?gliche Vorhersehbarkeit und Durchsetzbarkeit der Rechtslage angewiesen sind. Das entspricht nicht dem Blickwinkel des Richters, der nach Einzelfallgerechtigkeit in einem Rechtsstreit zwischen zwei konkreten Parteien strebt, aber auch nicht der begleitenden Wissenschaftler, die schon aus Gründen der Profilierung im wissenschaftlichen Umfeld zu innovativen und nicht selten gesetzesfernen Konzepten neigen. Der folgende Beitrag pl?diert daher für einen judicial und academic self-restraint, der sich unter Berücksichtigung der überindividuellen Auswirkungen um eine ermessensund beweisarme Rechtsatzbildung bemüht. Umso mehr sollte sich auch der Gesetzgeber des Postulats der Rechtssicherheit im Sinne der Rechtsklarheit, -stabilit?t und -durchsetzbarkeit und vor allem auch im Sinne der Vorhersehbarkeit richterlicher Entscheidungen wieder st?rker bewusst werden.     

Explaining Reforms of Parliamentary Minority Rights: A Theoretical Framework with Case Study Application

How can we explain institutional reforms that redistribute institutional power between the parliamentary majority and minority? This paper proposes an informal theoretical model to explain such reforms in European parliaments based on congressional literature and inductive explanations from case studies. The article argues that political parties as the relevant actors pursue institutional reforms based on their substantive goals, their current and expected future government status, transaction and audience costs of reforms, second-order institutions that regulate the relative influence of actors in changing parliamentary rules, and the institutional status quo. Hypotheses derived from this model are tested with a qualitative case study of all standing order reforms in the Austrian parliament from 1945 to 2014. The empirical analysis finds support for various hypotheses and their underlying causal mechanisms. As Austria constitutes a least-likely case, the evidence provides strong support for the theoretical model.     

Human capital and social capital in criminal networks: introduction to the special issue on the 7th Blankensee Colloquium

This essay and review on criminal network analysis provides an introduction to the special issue “Human Capital and Social Capital in Criminal Networks”. It traces the history of the application of network analysis in the study of organized crime since the early 1970s. It argues that while criminal network analysis has brought a new level of methodological rigor to the study of organized crime, a number of limitations have become apparent. These include the problem of missing data and the challenges encountered in adequately capturing latent structures, individual characteristics of network members and socio-ecological conditions.     

Violence in development: the logic of forced displacement on Colombia's Pacific coast

A progressive piece of legislation in 1993 granted collective land rights to Colombia's black communities living in the rural areas of the Pacific coast region. This measure aimed partly to support sustainable development strategies in the region through territorial empowering of local communities. Yet 14 years later, the escalation of the country's internal conflict into the Pacific region has created unprecedented levels of forced displacement among rural black communities. Once referred to as a ‘peace haven’, the Colombian Pacific coast is now characterised by new spaces of violence and terror, imposed by warring guerrilla and paramilitary groups, as well as the armed forces. This article examines the nature of the externally induced violence in the region and shows how specific economic interests, in particular in the African Palm sector, are colluding with illegal groups that are used to spread fear and terror among local residents, to make them comply with the requirements of these economic actors.
