The value of the acid phosphatase spot test in the primary visualization and identification of seminal traces is hampered by the sensitiveness of the enzyme to biodegradation. An alternative spot test is proposed, based on the high concentration of the more stable zinc metal in seminal plasma. The proposed zinc spot test is simple and suitable for on site investigation. Although the sensitivity in fresh stains is lower than that of the acid phosphatase spot test, this is largely compensated by the lower sensitiveness to biodegradation. The specificity for semen is higher than that of the acid phosphatase spot test. In vaginal swabs it was nevertheless seen, that samples should be taken within 24 h after alleged sexual assault to give reliable results. 相似文献

This paper studies aspects of sequential choice (and elimination) through the ‘routewise’ application of choice. (A choice is a mapping of the subsets of a set X into their respective subsets.) This approach sheds some further light on the ‘path-independence’ of choice, as well as on the logical structure of several rationality criteria for choice, as expressed through the properties of the comparison (or preference relation) revealed by a choice. The results bear particular relevance to the theory of collective choice. 相似文献

Microbiologic analysis of different soil samples was undertaken to assess the value of this method for forensic purposes. Three groups of micro-organisms were isolated on selective media: bacteria, fungi, and actinomycetes. Comparison of the morphology of the colonies led to the conclusion of non identity of the soil samples under examination. The method was applied to soil traces on articles of clothing, trousers, shoes, and stockings. It was found that the soil did not originate from the suspected scene of a crime. Examination of the microbiologic soil composition does not provide an absolute certainty of identity, but it is highly reliable. 相似文献

In the Netherlands, the prostitutes' rights movement emerged with the formation of an influential coalition of feminists and policy-makers who devoted themselves to an improvement in the juridical and social position of prostitutes. By seeking to connect into the priorities of the government's emancipation policy, this coalition succeeded in placing the issue of prostitutes' rights onto the political agenda. This paper addresses the question why this policy has failed to strengthen the position of prostitutes. By analyzing both the factors which enabled the initial prosperous development of the prostitutes' rights campaign as well as the conditions under which the turning-point arose, it is concluded that everything went smoothly as long as professional prostitutes monopolized image-formation. The process failed at the moment that policy-makers incorporated multi-problematic categories of prostitutes. In place of the intended social integration of all categories, the prostitutes' rights campaign led to a strengthening of the stigma that is attached to prostitution. 相似文献

The sensitivity and specificity of a zinc spot test for the detection of semen were compared with those of an acid phosphatase detection method. As screening techniques both tests were found to be very sensitive, but the zinc test was more specific and was more reliable in older and especially in deteriorated specimens. It is concluded that the zinc spot test deserves at least the same place as the acid phosphatase test in the primary investigation of suspected semen stains and might well be the test of choice in older and poorly preserved stains. 相似文献
