This paper discusses results of a supercritical fluid extraction-gas chromatography/mass spectrometry (SFE-GC/MS) study of small samples ( 100 microg to 1 mg) of human scalp hair. The method offers a number of benefits including greater sensitivity than liquid extraction methods because the entire extractable mass is transferred to the analytical system, compared with only a few percent from a conventional liquid extraction/injection. The project's goals were to determine if SFE-GC/MS analyses of the surface-extractable components of an individual's hair yield consistent chemical profiles and to investigate if the profiles are sufficiently different to distinguish them from those of other individuals. In addition, the mtDNA sequences from ten of the same individuals used in the SFE-GC/MS study from four family units were determined, and, while the families were distinguishable, the maternal relations yielded identical sequences. In tandem, SFE-GC/MS and mtDNA techniques may provide valuable complementary data from forensic hair samples. 相似文献

A major source of oppression in industrial and post-industrial society is the restrictive and highly authoritarian nature
of the workplace. One response is to democratize the workplace by increasing the participation of workers in making decisions
and in choosing and evaluating managers as well as sharing in the ownership of the firm. These are not new ideas, and there
are many examples of organizations pursuing various forms of democratic practices. However, a major objection is that such
participation would compromise economic and other types of organizational productivity. This article examines the empirical
support for that argument over a wide range of types of organizations in which workers participate in important decisions
affecting their welfare. The overall results of this survey across many different forms of work organization suggest that
the evidence supports the opposite conclusion, that worker participation increases productivity, particularly when workers
share the benefits of higher productivity. The challenge is to ascertain ways of spreading these practices more widely. 相似文献

De‐identified wound data from 197 homicidal gunshot postmortems were obtained between 2000 and 2008. Forensic ballistics data were only available for cases between 2004 and 2008. Males represent 91% of gunshot victims and were struck in the thorax/abdomen with an average of 2.3 bullets. The type of firearms involved were semi‐automatic pistols in the predominant caliber 9‐mm Luger and assault rifles in caliber 5.56 × 45 mm and caliber 7.62 × 39 mm Soviet, using full metal jacket bullets. The majority of shootings occurred at ranges of 1 m or greater. The most common bullet path was front to back in 66% of cases. Entry wounds occurred more often on the left side of the thorax, abdomen, and back. The most common critical organs/tissues to sustain bullet trauma in descending order were as follows: heart, lungs, liver, aorta, spleen, kidneys, and vena cava. Ribs were struck by most bullets that entered the thorax. 相似文献

This article presents findings from a qualitative study of seventy-one New York immigration lawyers who are engaged in private practice. It focuses on the lawyers' backgrounds, career paths, and early professional training and describes, inter alia, the unusual diversity of this bar, the lawyers' reasons for practicing immigration law, the ways in which they learn to practice law, and the strong sense of community within the private immigration bar. It uses the idea of communities of practice to help understand how lawyers learn from their colleagues and are influenced by them. The article identifies several factors that may contribute to the supportiveness of the bar and the strong sense of community within that practice specialty, notwithstanding its great diversity. It concludes by making some preliminary comparisons between immigration lawyers and lawyers in other practice specialties and by identifying some questions for future study. 相似文献
