Volatiles emitted by decaying human remains are in the focus of recent research. The identification of core volatiles in this field is of high importance, because cadaveric volatiles generally show high variation. In this study, the volatile profiles of five mice (Myodes glareolus) were sampled with charcoal filter tubes from their time of death until advanced decay. Eleven compounds were quantitated by means of gas chromatography–mass spectrometry. Electroantennographic experiments with female Calliphora vicina antennae led to the identification of dimethyl trisulfide, dimethyl disulfide, nonanal, hexan‐1‐ol, 1‐octen‐3‐ol, 3‐methylbutan‐1‐ol, and heptanal as electrophysiologically active compounds. When these were compared, dimethyl trisulfide (17 ng/μL) and dimethyl disulfide (11 ng/μL) were found to be emitted in higher concentrations. The roles of these compounds and nonanal as core volatiles for cadaver detection or postmortem time determination and their correlation to the stages of decay and the accumulated degree days are discussed.  相似文献

One crucial element for the evolution of cooperation may be the sensitivity to others?? efforts and pay-offs in comparison with one??s own costs and gains. If an individual responds to a disadvantageous reward distribution, then it would likely increase its relative fitness compared with those who do not (Brosnan & de Waal, Nature 428:140, 2004). Recent experimental research indicates that sensitivity toward unequal reward distribution is not a uniquely human trait; non-human primates react to inequity if they witness a conspecific that obtains a more attractive reward for the same effort. However, primates are not the only species that cooperate and thus would benefit from inequity aversion. Canids also frequently cooperate with group members (e.g., wolves, wild dogs, etc.) or humans (domestic dogs), allowing for the possibility that they also are sensitive to the reward distribution. We report the findings of two studies of dogs?? responses to inequity and the social factors that mediate such responses. In the first study, we investigated whether domestic dogs showed a response to the inequity of rewards received for the same action in pairs of familiar dogs. We found that dogs showed significant behavioral differences when tested without food rewards when in the presence of a rewarded partner compared to the baseline and asocial control situations. This indicated that the presence of a rewarded partner matters (Range, Horn, Virányi, & Huber, Proc Natl Acad Sci USA 106(1):340?C345, 2009). In contrast to primates, dogs did not react to differences in the quality of food or effort. In the second study, we analyzed whether individual (motivational or personality) characteristics determined the response of each subject to unequal reward distributions or whether the subject??s responses depended on the specific relationship they had with its partner. We found that individual motivation and the quality of the relationship influenced the dogs?? performance in test conditions, but that these factors varied across the control and reward inequity conditions. Overall, our results suggest that inequity aversion in dogs is conditional on their and their partner??s rewards. Whether inequity aversion is based on the same mechanisms in both humans and non-human primates is still unclear.  相似文献

The Czech–German borderlands are an archetypal European border region. They evoke not only Cold War histories, but also shelter layers of European memories of the ethnic reshaping of early post-war Europe. By means of life story interviews with German speakers of the border region, this article analyzes the symbolic meaning of and the individual dealing with the local Iron Curtain. It will shed light on the biographical and narrative interconnectedness of experiences of ethnic cleansing in the early post-war period and retrospective perceptions of the Iron Curtain in these borderlands. In particular, it inquires whether and to what extent the local Iron Curtain intensified fractures caused by the region's post-and pre-war attempts to halt the multiethnic composition of the border communities. The article suggests that the local Czech–German Iron Curtain would have never endured as strongly if the border communities' common identity had not already been severely damaged in the course of the region's traumatic history and forced population transfers.  相似文献

The paper explores the long road to the Federal Constitutional Court's 2006 landmark decision on the unconstitutionality of the century-old prohibition of output-based remuneration of lawyers, analyses the court's ruling and outlines the regulation of speculative fee agreements that is now in place in Germany. Another focus of the paper is an analysis of how the change has affected the German legal services market, drawing on empirical research on the subject carried out between 2006 and 2014.  相似文献

The currently accepted narrative regarding WWII in China suggests that Nationalist China and the Third Reich had no diplomatic connections after their official break of diplomatic relations in July 1941. Based on archival material from Germany, China and Taiwan, this article challenges this narrative. As I hope to demonstrate, communications between Germany and China continued well after July 1941 through back channels. From Switzerland, Chinese agents maintained connections with the German party intelligence service (RSHA), and Germany acted as a mediator between China and Japan. It is the role that intelligence personnel played in maintaining this communication channel and their role in clandestine Sino-German relations, which form the foundation of this paper.  相似文献
