The individuality of fibres used to provide forensic evidence--not all blue polyesters are the same.
Fibres used in forensic casework suffer from a disadvantage common to other forms of trace evidence--it is not possible to state with absolute certainty that they originate from a specific source. Target fibre studies, population studies and research on 'blocks of colour' have effectively demonstrated the polymorphism of textile fibres (particularly man-made ones) and have shown that when a fibre is believed to have a specific putative source, the chance that it has originated from a different source purely by coincidence is extremely remote. A study by Houck MM (Houck MM, Inter-comparison of unrelated fibre evidence. Forensic Science International 2003; 135: 146-149) has shown that no coincidental matching fibres were recovered from items of clothing examined in 20 unrelated crimes. The study involved over two million comparisons. This work goes a step further, and using the example of blue polyester fibres shows that even within a very narrow segment of the whole general fibre population, many examples of a specific colour/type of man-made fibre taken from random sources can be compared and the chance of any two being the same is very low. These studies should help to show the specificity and value of transferred fibres in providing forensic evidence. 相似文献

This article tests cross-nationally the minority group threat thesis that public sentiments toward repressive crime-control policies reflect conflicted racial and ethnic relations. Using multiple data sets representing France, Belgium, the Netherlands, East and West Germany, Italy, Luxembourg, Denmark, Great Britain, Greece, Spain, Finland, Sweden, Austria, Canada, Ireland, and Portugal, we examine whether racial and ethnic intolerance—animus, resentments, or negative sentiments toward minorities—predicts greater support for the death penalty. Our results reveal that the respondents were significantly more likely to express support for capital punishment if they were racially or ethnically intolerant while controlling for other covariates of public opinion. These findings indicate that the link between support for capital punishment and racial and ethnic animus may occur universally in countries with conflicted racial and ethnic relations. 相似文献

This paper explores the multi-layered representations of violence and crime in the recent Hollywood film Gangs of New York [Scorcese (2003) Miramax]. We use our exploration of this film to suggest that popular culture, even through its most mainstream products, can be seen as a critical criminological space where alternative views of law, crime and the state are made available. Rather than understanding Hollywood movies simply as vehicles for disseminating conventional mores, we suggest that they can furnish critical (and complex) points of view on law and crime and that the project of a critical criminology can be strengthened by engaging more forthrightly with these ubiquitous cultural forms. 相似文献

This paper argues that corruption is a product of self-aggrandizement; of unrealistically low remuneration which makes it impossible for public servants to live within their legitimate means; and of a closed political system which inevitably tends to exclude aggregated interests'. Corruption leads to loss of much needed revenue and human talent for development, distorts priorities for public policy, and shifts scarce resources away from the public interest. The mutual distrust that results among the different sections of society, and the growth of despondency in the general public, are incompatible with the requirements for successful public policy. The main theme running through the paper is that political instability, corruption and underdevelopment are mutually reinforcing. The paper finally outlines certain measures that need to be taken in order to clear the path for sustained growth and development. 相似文献

New York State experimented with replacing their litigation-oriented system for achieving toxic dump site cleanup with one promising to lower transaction costs through alternative dispute resolution. Our analysis of outcomes is informed by three generations of implementation work focusing on (1) the motivations and incentives shaping individual behavior, (2) the larger organizational and political factors associated with variation across cases, and (3) the generic properties of policy implements. This mosaic approach to explanation produces, we believe, a more lifelike picture of use to policy makers for understanding the dynamic and interrelated nature of their choices. 相似文献
