A retrospective analysis concerning deaths in the bathtub was carried out in the Institute of Legal Medicine in Hamburg. The study includes 245 death cases between 1971 and 1988 (1% of all autopsies). 66 cases proved to be natural deaths, 76 were classified as suicides, 39 as accidents and 13 as homicides; 51 fatalities remained unclear with respect to one of these groups. Among the natural deaths sudden cardiac deaths were dominating (n = 39), among the suicides the intoxications (n = 37) and electrocutions (n = 20), and among the accidents the intoxications by carbon monoxide (n = 17) and electrocutions (n = 12). Out of 13 homicides only 2 were committed directly in the bathtub: One by drowning of a child and one by electric current via a hair dryer; in the other cases the dead body was put into the bathtub post mortem. About 50% of the victims were alcoholized. Signs of drowning were present in about 40% of all cases; the most frequent finding was emphysema aquosum.  相似文献

A simple and reliable previously reported extraction procedure has been extended to the analysis of a wide range of basic and neutral drugs in postmortem blood and other tissues. The method employs 200 microliters of blood treated with water and ammonia and extracted with diethyl ether. The concentrated extract is generally sufficiently clean for direct analysis by gas chromatography and high pressure liquid chromatography. Recovery, precision and linearity data are presented for selected drugs.  相似文献

The alleles present at the HLA DQ alpha locus may be typed by either allele specific oligonucleotide (ASO) probing or by restriction mapping, referred to here as amplification restriction fragment polymorphism (ARFP) analysis. ASO typing relies upon hybridization principles, whereas ARFP typing relies upon restriction site analysis. Dot-blot ASO typings which are of doubtful interpretation may be directly checked by ARFP analysis. Aliquots of the PCR products amplified using the commercial Amplitype HLA DQ alpha system are digested with suitable restriction endonucleases. Electrophoresis, blotting and detection of biotin-labelled restriction fragments provides a sensitive and robust typing method suited to forensic analysis.  相似文献

Performance management has been a focus of scholars and practitioners for more than 25 years, yet the use of performance information has not greatly expanded as a result of this attention. Acknowledging that performance measurement is not an end in itself but rather a means to enhance focus on results and value, this article evaluates the determinants of the use of performance information by local government administrators. An online survey was administered to local government employees involved in the 2015–16 Florida Benchmarking Consortium. Analysis of the data demonstrates that institutionalization of performance measurement has the strongest statistically significant positive association with the use of performance information, followed by the design adequacy of the performance measurement system.  相似文献

I advance a theory about how compulsory voting affects the behavior of political parties. The theory suggests that parties will pivot toward programmatic vote‐seeking strategies and away from clientelistic tactics, such as vote buying, where voting is compulsory. I test my expectations in three separate studies, using several data sources and empirical approaches. In Study 1, cross‐national analyses show that parties behave more programmatically under compulsory voting and that vote buying is less common where voting is mandatory. In Study 2, synthetic control and difference‐in‐differences analyses show that a switch to compulsory voting in Thailand produced an increase in programmatic vote seeking. In Study 3, a list experiment conducted in tandem with a natural experiment shows that compulsory voting leads parties to rely less on vote‐buying tactics in Argentina. I conclude by discussing the implications of these findings, which together are broadly supportive of my theoretical expectations.  相似文献
