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

This article assesses whether police Field Training Officers (FTOs) display patterns of attitudes that distinguish them from non-field training officers. The analysis focuses on attitudes toward four important groups: fellow officers, immediate supervisors, top managers, and neighborhood residents. Interview data used were collected from Indianapolis Police Department (IPD) during the summer of 1996. Findings show that FTOs are more critical of their immediate supervisors and district managers than non-FTOs, whereas FTOs and non-FTOs hold similar attitudes toward their co-workers and neighborhood residents. Implications for future research and policy are discussed.  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

A 35 years old student with prior suicidal tendencies was found dead laying enclosed in a plastic-bag together with four plastic-bags of minor capacity. Three bags were opened by cuts and empty, one bag contained 73 1 of 83.2 Vol.% carbon monoxide. Postmortem carboxyhemoglobin concentrations in blood of five different regions of the corpse ranged from 80.3% to 93.4%. From the circumstances--chemicals and apparatus--it could be reconstructed that carbon monoxide was produced by the reactions of formic acid and sulfuric acid.  相似文献

Determination of ABO-blood group on human hair segments of 79 individuals was performed by means of modified Yada absorption-elutions technique. The studies were carried out with 4 micron thin cross sections of hair. In 79% of the cases it was possible to establish the correct blood group. Individual hair segments of 0.5 cm length yielded reliable results. Antigen identification was best with blood group B and most difficult of the AB type.  相似文献

In a typical laboratory “Investment Game” experiment, participants’ endowments are provided by the experimenter; thus, the worst case for the investor is that she loses all of her “found” money. By contrast, in naturally occurring environments, investment decisions can often lead to a loss of one’s own money. This paper investigates whether “trust” found in one-shot anonymous laboratory interaction is robust to “own money” environments. Our results show that, consistent with previous investment game results, most investors send a positive amount, and most trustees return at least the transfer amount, regardless of whether the investors purchase or are gifted their endowment. However, investments are on average lower when participants use their own money, and the fraction of maximum investments (the most “risky” investment decision) is only half as large under “own money” as it is under gifted endowments. Our results explain why one should exercise caution in placing trust in any government’s ability to spend other people’s money prudently.  相似文献
