A note on the status of discretion in police research

“Discretion” holds an unrivaled position at the core of the notional inventory employed in the study of criminal justice generally and policing particularly. Efforts to systematically define the term have been irregular and its status in the empirical literature is an ambiguous one. While spoken of as a quantitative aspect of the policing which influences behavior, measurement is rarely addressed. After sketching problems in present formulations, discretion is recast in terms of perceived job autonomy and an outline of two general constructs is contributed in hopes of renewing consideration of the potential relevance of the concept for police theory and research.     

友谊和相互理解的盛会——谈俄罗斯"中国年"

我的老朋友和同行冯绍雷教授请我谈一谈我对俄罗斯"中国年"的想法,对此我欣然应允。3月26日,俄罗斯"中国年"开幕式在克里姆林宫隆重举行。两国领导人——胡锦涛主席和普京总统在讲话中强调了中俄两国互办"国家年"的意义,强调了两国人民命运和两国主要发展目标上的历史共性。实际上,正是两国领导人自己提出了举办这种大规模活动的倡议。中国艺术家们在克里姆林宫剧院的大型演出,成为中国音乐、舞蹈和杂技艺术所取得的突出成就的真实展示。演员们的表演受到了     

"First pass phenomenon" of inhaled gas in the fire victims

We investigated the differences in the levels of carboxyhemoglobin (COHb), cyanide (HCN) and petroleum fuels (gasoline and kerosene) between left and right ventricular bloods from fire victims. COHb was slightly, and HCN and petroleum fuels were markedly higher levels in the left than those in the right. These effects were so called 'first pass phenomena' due to the circulation, diffusion and metabolization before the deaths of fire victims.     

A modification of the microplate method for reverse ABO typing of bloodstains and additional validation studies

The results of additional validation studies of a sensitive microplate hemagglutination assay for ABO reverse grouping of bloodstains are presented. The results of the validation study demonstrate the reliability of the microplate assay for use in routine serological casework. Based on these studies, the microplate assay has now replaced the Lattes crust test for ABO reverse grouping of bloodstains in the FBI Laboratory.
