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.

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.     

The interdisciplinary dimensions of the study of organized crime

This essay and review systematically charts the various influences from other areas of scientific research, including economy, psychology, and neurobiology, on the study of organized crime. Drawing on an analysis of American and international literature, metaphorical, and substantive references to other disciplines are highlighted on five levels of observation: the individual “organized criminal,” the activities these individuals are involved in, the associational patterns through which they are connected, the power structures that subordinate these individuals and collectives to common or particular interests, and the relations between these individuals, structures and activities on the one hand, and the legal spheres of society on the other. It is argued that a research program aiming at building up a cumulative body of knowledge is needed to overcome the shortcomings of the current eclectic use of concepts and theories from other disciplines.     

How do Asians evaluate Europe’s strategic involvement in East Asia?

Europe is neither in the centre of Southeast Asia’s nor of Northeast Asia’s strategic interest. For both, Asians and Europeans it has been equally difficult to articulate their visions of each other’s role in security matters. However, Asia recognizes positively the EU’s civilian dominated approach in peacekeeping missions, e.g. in East Timor or in Aceh. Europe’s contribution to the Asia Regional Forum has been rather modest. But due to the increasing importance of comprehensive security, Europe’s experiences as a soft power could well change this position, provided both sides pay more attention to the constraints of the two regions. China as the major power in the region is somehow caught between the devil and the deep blue sea: on one side, it neither wants nor expects Europe to play a strategic role in East Asia. On the other, it would like to see Europe to become a power of its own in a China-US-EU triangle. This paper is based on a speech given by the author in Paris/France on 8th December 2006 at a conference on ‘French and European Strategic Interests in East Asia’ organised by the ‘Asia Centre’ with the support of the Secrétariat général de la défense nationale (SGDN). Mr. Norbert von Hofmann is an independent consultant on Southeast Asian-European co-operation in Germany. Formerly he was the Head of the Friedrich-Ebert-Stiftung’s Office for Regional Cooperation in Southeast Asia in Singapore.
