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

Unwanted sexual attention (UWSA) encompasses unsolicited verbal comments, gestures, stares, and other noncontact behaviors made regarding one's sexuality and physical appearance. The present study examined the correlates and impact of such UWSA perpetrated toward girls by family members. The first objective of the study was to explore whether family climate is associated with intrafamilial UWSA. This included looking at three types of dysfunctional parenting styles (unaffectionate, unavailable, and patriarchal) as well as exploring the co-occurrence of UWSA by adult and child relatives. The second objective was to then measure the impact of such intrafamilial UWSA on childhood emotional health, after controlling for parenting style and the experience of more traditional forms of child sexual abuse (CSA). Of the 296 university women (mean age = 19) who participated in the study, 70% (N = 206) reported UWSA from a family member prior to age 18. Whereas each dysfunctional parenting style was related to presence of UWSA, a simultaneous multiple regression analysis indicated that two of the parenting styles, patriarchal and parental unavailability, also predicted frequency of nonphysical UWSA within the family. Presence of UWSA from a child relative was significantly correlated with presence of UWSA from an adult relative. Additionally, a hierarchical multiple regression, entering the three parenting styles simultaneously in the first step, childhood sexual abuse in the second step, and familial UWSA in the last step, indicated that the frequency of UWSA by family members significantly predicted poorer childhood mental health when controlling for the other variables. Overall, results indicate that while the specific parenting styles which co-occur with UWSA may be detrimental in their own right, the impact of UWSA on girls appears to be above and beyond that of either parenting styles or CSA. Clinical implications are discussed. 相似文献

After the Agreement on the Trade-Related Aspects of Intellectual Property Rights (TRIPS) came into operation in 1995 developing countries have found themselves in a process of continual negotiation over intellectual property rights and access to medicines. These negotiations have taken place in the World Trade Organization and in the context of free trade agreements. The paper suggests that the only real win for developing countries has been the Doha Declaration on the TRIPS Agreement and Public Health in 2001. What have been the lessons for developing countries in a decade of negotiations over access to medicines? Drawing on themes of rule complexity and regulatory ritualism the paper discusses four key lessons for developing countries. It concludes by arguing that developing countries will do better if they adopt a networked governance approach to negotiation rather than continuing to rely on traditional coalition formation. 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

The DNA commission of the International Society of Forensic Genetics (ISFG) was convened at the 21st congress of the International Society for Forensic Genetics held between 13 and 17 September in the Azores, Portugal. The purpose of the group was to agree on guidelines to encourage best practice that can be universally applied to assist with mixture interpretation. In addition the commission was tasked to provide guidance on low copy number (LCN) reporting. Our discussions have highlighted a significant need for continuing education and research into this area. We have attempted to present a consensus from experts but to be practical we do not claim to have conveyed a clear vision in every respect in this difficult subject. For this reason, we propose to allow a period of time for feedback and reflection by the scientific community. Then the DNA commission will meet again to consider further recommendations. 相似文献

East Asia, including Northeast Asia and Southeast Asia, has developed tightly-linked production/distribution networks through
globalizing corporate activities. The vertical chain of production in East Asia has been even more sophisticated than economic
integration in East Europe or Latin America. However, the political environment of East Asia for trade and investment has
been far from borderless. The integration effort at the policy level has been very much limited so far, due to the historical
background as well as geopolitics surrounding East Asia.
The Asian currency/financial crisis provided these countries a historical turning point. After the burst of the crisis, East
Asians realized that they have to take care of themselves in their difficulties, not depending on outside forces. A natural
choice for them was to step into the realm of regionalism. In 1998, Japan and Korea officially announced that they would discard
the long-lasting GATT/WTO-only approach and adapt the multi-layered approach, including both regionalism and multilateralism.
The ultimate goal of regionalism would be a region-wide integration including ASEAN+3. As a steppingstone, Japan signed the
Japan-Singapore Economic Partnership Agreement (JSEPA) in January 2002. In a parallel move, the ASEAN and China Leaders announced
in November 2001 the establishment of an ASEAN-China Free Trade Area (ACFTA) within 10 years.
This article will follow up the most recent advancement of regional institutional building in East Asia with the emphasis
on peculiar characteristics of economic integration in the region and discuss its implications for Asia-Europe relations.
