In this case study, the body of a 45‐year‐old man was exhumed after 1 year at the request of the public prosecutor to assess whether the death was caused by drug consumption. Toxicological analyses were performed on several matrices, including liver, kidney, and the alternative matrices hair and teeth. The systematic toxicological analysis (STA), which consisted of basic and acid liquid/liquid extraction and gas chromatography–mass spectrometry (GC‐MS) analysis, showed the presence of opiates in each of the matrices analyzed. Subsequently, to confirm and quantify the presence of opioids, samples of each of the matrices were subjected to solid‐phase extraction and specific GC‐MS analysis. The case presented demonstrates the possibility of drug detection in an exhumed body that has been buried for 1 year, despite the problems of quantitative interpretation of the data, and that toxicological results could be useful along with other forensic evidence.  相似文献

This study examined the perspectives and definition of leadership by women and mothers with children (n = 40) affiliated with Oxford Houses, a communal mutual-help recovery setting. Participants were asked questions relating to their experiences living in an Oxford House including the strengths and challenges encountered and how leadership impacted the stability in their house. Results illustrated the value of female leadership and highlighted the characteristics deemed important for women leaders in Oxford House, as well as some differences between these women's perception of leadership and the standard definition of leadership. The implications of the findings and how they may be useful to women's and mothers' with children houses are discussed.  相似文献

Human remains detection dogs (HRDD) are commonly used by law enforcement agencies to search for cadavers. Biological material is typically used as a training stimulus, also called aids, to train dogs to recognize the smell of cadavers. While HRDD training approaches have received extensive attention, information remains limited on the olfactory cues used to train them. Here, we aimed to decipher the chemical basis of detection dog olfaction. Five specific objectives were explored to precise whether the composition or the concentration of the training aids drives the HRDDs responses. We recorded the behavioral responses of four HRDDs exposed to different cadaveric-like smells. We found that HRDDs recognized a simplified synthetic aid composed of cadaveric compounds. The lowest concentration at which HRDDs continued to perceive the cadaveric smell was determined. HRDDs were not impacted by slight modifications to the chemical composition of a blend of odors that they have been trained with. HRDDs associated sulfur and nitrogen compounds as human cadaver. Our findings highlight a lack of specificity of HRDDs to cadaveric compounds, which could lead to error of detection. Moreover, all dogs did not positively respond to the same blends, despite being trained with the same aids and procedure. However, we confirmed that dogs could be trained with a simplified blend of molecules. The chemical composition of a training aid has, therefore, high consequences on the performance of the trained animal, and this conclusion opens additional questions regarding olfaction-based detection animals.  相似文献

The unusual size and persistence of the gender gap in political knowledge is perplexing in comparison to other dimensions of politics. Building on situational explanations of political engagement, this article claims that women’s and men’s specific adult roles lead to an enlargement of the gender gap in knowledge. The present study analyses men and women’s levels of political knowledge at different life stages by means of two unique datasets specifically collected to measure what people know about politics. Findings show that adult roles provide more opportunities for men to gain political knowledge than for women. Furthermore, the comparison of levels of political knowledge in two such dissimilar countries as Finland and Spain suggests that while gender equality policies are successful in tearing down some of the obstacles that hinder women’s contact with the political world, they are still insufficient to completely bridge the gender gap in political knowledge during adulthood.  相似文献

While the economic vote exists in Western democracies, the question of its stability remains a subject of controversy. This article focuses on two possible factors behind the instability observed: the endogeneity problem and the restricted variance problem. The former concerns the influence of partisan thinking on economic perception, while the latter concerns the influence of economic crisis, when virtually all voters may perceive a bad economy. These problems are examined using panel data from the Spanish national elections of 2008 and 2011. After various causality tests, it is concluded that the economic vote was influential in both contests, but apparently less so in 2011. It is shown in the article that the initial 2011 result misleads because of the statistical artifact presented by the restricted variance problem. Thus, an alternative strategy for exogenising economic perceptions is developed using aggregate economic measures in a pooled cross‐sectional design whereby it is demonstrated that the economy mattered greatly under the economic crisis of 2011. This estimation strategy could be applicable to other Western democracies experiencing such economic crisis.  相似文献

This article presents the first record of Hermetia illucens larvae on a human corpse in Spain (the second case report in Europe). Prepupae of H. illucens, and other insects, were recovered from the dead body of a 72-year-old man in an advanced stage of decomposition. The body was located in Reus (NE Spain), in October 1998. This article provides additional biological data on experimental studies and an update on the geographic distribution of this species in the Iberian Peninsula.  相似文献
