An improved method for detecting diatom in blood is reported. Blood of cadavers was obtained by cardiac puncture at inquest or from the left atrium directly at autopsy. The blood was hemolyzed by sodium dodecyl sulfate (SDS) and filtered through membrane filter (47 mm in diameter and 5 microns in pore size). When the blood was putrefied, two or three pieces of membranes filters were needed because of choking membrane pore. The membrane filters were digested with fuming nitric acid and diluted with distilled water. The diluted solution was filtered through membrane filter (25 mm in diameter) again. After drying the membrane filter was immersed in oil. Diatoms on the membrane filter were clearly observed microscopically. 相似文献

The chemical substances of perspiration found in latent fingerprint residue may hold the key for dating latent fingerprints. To study the chemical transformations of these components as a function of time and environment, fingerprint residues from four males and four females were analysed by thin-layer chromatography (TLC) and high performance liquid chromatography (HPLC). Three major and two or three minor components were detected by both methods and the variation in the quantity of the major components with time was observed. 相似文献

Assessing law enforcement preparedness to address Internet fraud 总被引:1,自引:0,他引:1
Recent societal concern regarding computer crime was well documented in the research literature. To date, however, modest research addressed how large, local police and sheriff's departments confront Internet fraud. Using data collected from surveys distributed to the seven hundred largest police- and sheriff's departments, the present article addresses law enforcement: (1) preparedness to enforce Internet fraud crimes; (2) perceptions of Internet fraud; (3) cooperative policing efforts; and (4) Internet fraud information dissemination practices. Among other things, results suggested that individuals within these departments believed Internet fraud was problematic, although they lacked the resources to properly address the problem. These results are discussed as they relate to the organizational design of law enforcement agencies and their potential to adapt to innovative crimes. Suggestions are offered for a more effective approach to confronting Internet fraud. 相似文献

At the wheels of railroads and streetcars, the law of accidental personal injury, known as negligence, became a discrete body of law between 1870 and 1920. The defining component of negligence was "fault"–the notion that the individuals (injured and injurer) must have failed to act according to some minimal standard of caution. Theorists of the history of negligence have explained that the conduct of all was measured against what a "reasonable man" would have done under the circumstances. The author here challenges this fundamental assertion. Through trial records, lawyer's written arguments, and appellate opinions, she reconstructs the critical role of gender in shaping the law of accidental injury. As she argues, in 19th- and 20th-century America, injury was a gendered event. The fact that courts in these years held men and women to different standards of care undermines theorists' arguments that economic considerations drove the law of accidental injury. Moreover, the reification of gender nm in private law, in turn, vitally affected the experience of gender in turn-of-the-century America. 相似文献

Taiwan is known for rapid economic growth, but in 1988, the government ended 40 years of martial law, resulting in greater political and social freedoms. This paper explores the influence of economic, social, and political structures on crime in the Republic of China on Taiwan. A time series analysis examines the structural correlates of crime in Taiwan from 1964 to 1990. Both total crime and burglary/larceny rates are regressed on seven independent variables derived from various theoretical perspectives. The results support Hagan's power-control and Christie's crime-industry perspectives for total crime, while measures assessing lack of economic means and the economic deprivation were significant for burglary/larceny. 相似文献
