This paper explores a popular yet highly destructive form of property crime — graffiti vandalism. The localities of such destruction selected for study were male and female restrooms. Three hundred and ninety-two cases were collected and analyzed. Prior research theorized the existence of a significant difference in the amount of graffiti produced between the sexes. (It was believed that males produce more graffiti than females). Analysis, however, revealed equal production of graffiti by males and females.Content differences between the sexes were hypothesized. The content categories included homosexual, heterosexual, nonsexual (humorous and political statements) and racial graffiti. The findings as they relate to content differences between the sexes are presented and discussed relative to sex-role socialization theory.  相似文献

We describe the forensic science application of a method for quantification of human genomic deoxyribonucleic acid (DNA). The two cases cited in this report involve DNA samples extracted from skin tissue and bloodstained clothing recovered from different crime scenes. High-molecular-weight DNA was recovered from both specimens, and the concentrations of these DNAs were estimated to be approximately 0.5 microgram/microL by ethidium bromide/agarose gel electrophoresis. Using the human-specific DNA probe p17H8 (locus D17Z1) to quantify the amount of human genomic DNA in these samples, it is shown that less than 1% of the DNA isolated from the skin tissue is of human origin and that the DNA isolated from the bloodstained clothing is effectively devoid of human DNA sequences. These case examples illustrate the need to quantify not only the total amount of DNA recovered from forensic casework material, but also the proportion of the DNA that is of human origin.  相似文献

Many law enforcement agencies are currently responding to the problem of online crime by establishing proactive investigative units that track criminals on the Internet. Not only do these specialized teams face problems in the area of emerging technology, they are also faced with handling emerging legal issues. The current research examined the issue of the entrapment defense, and how previously established physical realm doctrine could be applied to the investigation of online crimes such as child pornography. Relying on previous case law it would appear that entrapment claims related to online sting operations involve consideration of: a) did the law enforcement officer continuously contact the suspect with the intention of trying to convince the individual to engage in a particular type of behavior, b) how long was the relationship between the undercover officer and the suspect, and c) how much, if any, reluctance to commit the criminal act did the suspect provide evidence of?  相似文献

The doctrine of successor liability transfers tort liabilityarising from the seller's past conduct from the seller to thebuyer. If the buyer has as much information about the liabilityas the seller, all beneficial acquisitions take place and theseller takes the efficient level of precaution. However, ifthe seller has more information about the liability than thebuyer, not all beneficial acquisitions are consummated and theseller takes a suboptimal level of precaution. I argue that,in the presence of information asymmetry, the courts shouldincrease the damages against the (potential) seller to providebetter incentives to take precaution while decreasing the damagesagainst the buyer to encourage more beneficial asset sales.  相似文献

What explains the persistence and proliferation of the resident ambassador? Why is the role apparently important both to the conduct of international affairs and to the work of governments? I do not try to propose a new theory of ambassadors, but I do offer conclusions about the nature of living in a globalized society of states where the economic logic of markets and the political logic of communities are at cross-purposes. It is a world in which we depend on institutions to help us maintain order and stability. Ambassadors are one of those institutions. At one level they are the concrete day by day reproduction of the society of states. At another level they act on behalf of the members of their community, helping that community to maintain its strength and cohesion by doing what needs to be done, abroad. An increase in the intensity of interactions among states, therefore, seems to lead to an increase in diplomatic representation facilitated rather than impeded by the new technologies of transportation and communications. Ambassadors are still lying abroad, it seems, because changes in technology have brought 'abroad' much closer to home while the myriad effects of globalization have made much more of abroad relevant to people and their governments. Far from being in decline, the resident ambassador seems likely to continue flourishing.  相似文献

A synoptic study of six cases of self-inflicted sharp force injuries is presented, where young, mostly female people had simulated assaults to gain sympathy or other personal advantage. The morphological distinctives of simulated assault wounds from such of real assault are worked out and the common situative and motivative background is cleared up.  相似文献
