Correlation of age and ossification of the medial clavicular epiphysis using computed tomography

OBJECT: The aim of this study was the examination of relationship between the age and the ossification of medial epiphysis of the clavicle referred to CT examination. MATERIALS AND METHODS: Concerning the epiphyseal ossification of the clavicle CT's of 100 patients (50 male and 50 female) between 16 and 25 years (10 patients for each year) were analyzed by three viewers. RESULTS: In the legal relevant age segment (16-25a) we saw a turnover from stage 3 to stage 4 at the age of 21 years. The calculated empiric distribution function showed 95% of stage 4 over 21 years while 75% of the patients with stage 3 were under 21 years. A reconstruction kernel suitable for osseous structures should be used, images should be viewed or presented in a bone window. CONCLUSION: According to these results it can be concluded that a person with stage 4 is probably 21 years or older, while a stage 3 leads to an estimated age under 21 years. On the other hand, a confidence level of 99.67% is not reached. Therefore, CT of the medial epiphysis of the clavicle will only be suitable for age estimation around the age of 21 years, if this relevant statistic obstacle is defeated. Bearing this in mind, further studies are needed to evaluate slice thickness as the most critical parameter.     

Post-mortem examination prior to cremation--an instrument to verify the quality of medical post-mortems and uncover non-natural deaths?

The external post-mortem examination, its deficient quality and possible causes have been the subject of numerous political and professional discussions. The external post-mortem examination is the basis for the decision whether further criminal investigations are required to clarify the cause of death. It is thus an essential instrument to ensure legal certainty. Before cremation, a second external post-mortem examination is performed by a public medical officer to make sure that errors of the first post-mortem are corrected. In the present study, cases were retrospectively analyzed in which a forensic autopsy had been ordered on the basis of the results of the post-mortem examination performed before cremation. The entries on the death certificate regarding the manner and cause of death were compared with the autopsy results. Between 1998 and 2007, 387 autopsies were ordered after external examination before cremation. In 55 cases (14.2%), the autopsy revealed a non-natural death, although a natural death had been attested on the death certificate. In descending order, a wrong manner of death was attested by clinicians, general practitioners and emergency physicians. With regard to the place where the first external post-mortem had been performed the lowest error rate was seen in nursing homes. Concerning the cause of death, discrepancies between the first post-mortem and autopsy were found in 59.4% of the cases. In this respect, general practitioners and clinicians were ranking first, whereas in nursing homes the cause of death was wrongly assessed in over 70% of cases. At present, the medical post-mortem does not meet the required quality standards, especially with regard to legal certainty. Determination of the cause of death on the basis of the external post-mortem examination is a challenging task even for the experienced medical examiner. As to the categorization of the manner of death it has to be stated that non-natural deaths are often not recognized or that the possibility to certify a death as unclear is not sufficiently used. As a result, it seems important to demand intensive, qualified, additional training in external post-mortem examinations for physicians.     

Transitions in the negotiations on climate change: from prisoner’s dilemma to chicken and beyond

Frequently, international environmental negotiations have been analyzed in two-agent (2 × 2) games. Yet, in order to involve additional strategies, (3 × 3) games gained attention recently. We employ such a (3 × 3) game setting in order to depict international negotiations on climate change and integrate both the prisoner’s dilemma and the chicken games in this setting. We analyze transitions of negotiation states and describe how ancillary benefits and first-mover advantages influence agents’ behavior in the negotiations, when three different strategies or levels of climate protection efforts are available. Finally, we also integrate strategies to mitigate and to adapt to climate change into the analysis in the (3 × 3) game setting.     

Between man,woman and dog: Olive Schreiner’s The Story of an African Farm

The dog in Schreiner’s novel is represented both as an individualized human companion and as a figure of the social outcast. This split signification is homologous with other such instances in the novel – the anomaly of a “failed” bildungsroman, the narrative division between the real and the dreamlike, the aporia of human consciousness in the face of nature, the entanglements of gender, the problematics of race. Focusing on Waldo, Lyndall, and the dog Doss, the paper tracks the way in which the dog refracts not only the relation between human and animal but also a range of other relations in the novel, social and metaphysical. Reading the novel and its late nineteenth-century contexts of thought from the retrospective standpoint of the present – a hermeneutic position that is itself the site of a split signification – the paper considers the dog good to think with.     

Keynes,Friedman, or Monnet? Explaining parliamentary voting behaviour on fiscal aid for euro area member states

This article investigates the determinants of parliamentary support for international fiscal aid. Departing from the literature on presidential systems, it analyses an exemplary case of a parliamentary system, Germany. Two theoretical accounts are distinguished. The first perceives MPs as policy-seekers and focuses on the positioning of government and opposition parties and individual MPs on an economic left?right and a pro- versus anti-EU dimension. The second regards MPs as vote-seekers and presumes an electoral district connection. The statistical analysis of a new data-set containing information on 17 Bundestag roll-call votes from 2009 to 2015 finds support for the first account: voting in favour of fiscal aid measures is mainly driven by government membership and EU support. By contrast, neither economic ideologies, nor district or mandate characteristics influence support for fiscal aid. The article contributes to a growing literature on the domestic politics of international political economy.     

The influence of personality on violent victimization – a study on police officers

The current study aims to examine the influence of police officer characteristics, civilian characteristics, and possible interactions between both on violent victimization of police officers. Based on literature distinguishing between ‘provocative’ and ‘submissive’ victims, focus is given on effects of police officers’ personality in terms of the five-factor model plus risk-taking. Patrol police officers (n?=?1813) from Lower Saxony, Germany, completed a paper-and-pencil survey including personality assessments as well as questions about their last three police encounters. Binary logistic multilevel regression analyses demonstrate that police officers with higher scores on neuroticism and openness to experience were more likely to be violently attacked. Furthermore, agreeableness reduced police officers’ risk of violent victimization, while risk-taking and neuroticism increased their risk when confronted with a violent civilian. The study indicates that personality and especially traits that are assumed to provoke potential perpetrators were linked with violent victimization. It further stresses the need to include perpetrator attributes in victim studies in order to identify relevant interaction effects between both parties.     

Meeting local needs? Case study of a communication project in the Pacific Islands

The Internet has become a major source and vehicle for technological transfer and project development during the 1990s. Three Pacific Island countries—Fiji, Samoa and Vanuatu—were connected through Pactok, an inexpensive computer‐mediated communication (CMC) system originally developed for non‐government organizations (NGOs) through the Pacific Sustainable Development Networking Project (PSDNP). The PSDNP was established by the United Nations Development Programme (UNDP) in 1993 and funded by the UNDP until December 1996. Content analysis of the Project Document indicated that although the PSDNP aimed to improve access by these countries to scientific and technical information, an important underlying theme was to ensure these Pacific Island countries were connected to the Internet. It also appeared that the agency was keen for organizations in these countries to increase access to international information, with little regard for local and regional sources. Subsequent analysis of Pactok sites early in 1997 showed that the PSDNP had encouraged the project's primary stakeholders—regional organizations and NGOs—to join Pactok. However, international agencies such as the UNDP and other foreign assistance also have access to Pactok and are able to disseminate agency ideologies, objectives and priorities directly to users in Pacific Island countries.
