The concentration of thyreoglobulin (tg) was determined for death caused by hanging, strangulation by ligature, and throttling. Cases of sudden death (traumatic aortic rupture, penetrating wounds of the heart) were used for comparison. The mean values in cases of hanging (149.9±202.3 ng/ml), strangulation by ligature (193.1±173.3), manual strangulation (561.6±173.9) are distinguishable from violent acute deaths (23.3±27.6) and living healthy individuals (17.3±16.1). By means of statistical comparisons, significant differences were found between throttling and strangulation by ligature and between throttling and hanging (adjusted P<0.001). In connection with examination of the bodies high tg values can be regarded as a vital reaction in obstructive asphyxia. 相似文献

A growing body of evidence shows that minorities are disproportionately the targets of police brutality, but important theoretical questions about the causes of that inequity remain unanswered. One promising line of research involves structural‐level analyses of the incidence of police brutality complaints; however, existing studies do not incorporate variables from alternative theoretical explanations. Drawing on the community accountability hypothesis and the threat hypothesis, we tested the predictions of two prominent structural‐level explanations of police brutality in a study of civil rights criminal complaints. The study included cities of 150,000+ population (n = 114). The findings reveal that two community accountability variables—ratio percent Hispanic citizens to percent Hispanic police officers and the presence of citizen review—were related positively to police brutality complaints, partially supporting that perspective. Two threat hypothesis measures of threatening people—percent black and percent Hispanic (in the Southwest)—were related positively to complaints, as predicted. The relative degree of support for the two hypotheses is assessed. 相似文献

A number of recent studies have explored the consequences ofinterracial peer effects on the academic and social performanceof minority students. This article contributes to that discussion,focusing, however, on perceptions rather than behaviors. Theanalysis suggests that exposure to white peers is associatedwith declining perceptions of racial justice among black andLatino high school students. While cautioning against causalinterpretations of this finding, the article suggests that theintegrationist aims of Brown v. Board of Education will notbe satisfied without more thoughtful and vigorous desegregationefforts. 相似文献

A report of an international collaborative experiment to demonstrate the uniformity obtainable using DNA profiling techniques. 总被引:2,自引:0,他引:2

This paper describes a collaborative exercise intended to demonstrate whether uniformity of DNA profile results could be achieved between different European laboratories. It was shown that this goal can be obtained provided that a common protocol is followed (specifically the use of a common electrophoretic buffer as being the most important parameter). Generally, lower molecular weight loci (with lower molecular weight fragments) such as YNH24 perform better than higher molecular weight loci such as MS43a. The results of the exercise are discussed in relation to the objectives of the European DNA profiling group (EDNAP). 相似文献

With Asia's economy still booming in the second half of the 1990's “Asian values” were announced by some politicians (Lee
Kuan Yew, Mahatir, Ishihara, Mahbubani etc.) and contrasted with “Western values”. Soon a controversial debate within Asia
ensued (Kim, Fidel Ramos ea..), into which also the western democracies joined. The “West” however reacted rather defensively
to the new assertiveness of some Asian statesmen, inspite of the fact that the authors of this debate put into question the
western dominance in global value setting which has been in existence since the French revolution. But has this debate withstood
the test of time, the challenges posed by the recession in Asia and by the ever increasing globalization? Hardly. The crisis
has destroyed the notion that “Asian values” had been the main cause and guarantor of Asia's exorbitant growth rates.
While in the West Christianity forms the essential basics of culture, in Asia there is a multitude of coexisting - and frequently
confronting world religions. There is no other continent which in cultural and political terms is so contradictory and potentially
conflict ridden like Asia. “Asianism” as a concept was surely also intended as an instrument to integrate multiethnic Asian
societies with weak internal cohesion. At the same time it served to neutralize the human rights issue.
In the meantime the debate has become quieter and more dispassionate. In the developed West the notion gained acceptance to
abandon “Eurocentrism”. At the same time there is recognition that “Asian values” are not exclusive. Also in Europe the family
plays a special role. A debate on values is needed for societal integration – also in the “West” which should become more
aware of the need to reassert the origins of its own spiritual foundations. Following September 11th the west is well advised
to continue the dialogue on values with Asia.
