The fingernails of Mary Sullivan, the last victim of the Boston Strangler, were examined to determine if any genetic information about the murderer could be obtained. The nails were extremely friable necessitating the development of new techniques for isolating and purifying DNA. DNA yields from nails were optimized by using a NaOH-based preparation technique, which was simple, efficient, and minimized handling. Methods for selectively and thoroughly removing exogenous material on nails were also developed through use of a species-specific PCR assay, wherein mitochondrial DNA from the nail could easily be differentiated from DNA of contaminating cells.  相似文献

This article assesses the internal dynamics of the cartel party model. It argues that a party's endeavour to increase its societal reach by opening membership boundaries while keeping candidate selection local (two tendencies ascribed to this model), and the general need to maintain party unity, are difficult to reconcile. Therefore a fully fledged cartel party is organisationally vulnerable, which reinforces its resort to selective benefits (i.e. political appointments, patronage) whenever in government to satisfy organisational demands, a trigger intensifying party–state relations which is usually overlooked. Further, the dominant view of the ascendancy of parties' 'public face' needs to be qualified: the Irish Fianna Fáil, with its permeable boundaries and local candidate selection, reflects the cartel party model without a cartel at the party system level. Majoritarian dynamics have forced Fianna Fáil repeatedly into opposition which reveals the following: Fianna Fáil as a cartel party can afford to neglect its infrastructure on the ground as long as it is controlling government resources. In opposition its leadership initiates reforms to reinvigorate the party's infrastructure since it is pressed to generate organisational support through other means than distributing benefits.  相似文献

The basis of ethnic inequality is set during preschool age. This article aims to explain developmental ethnical differences by using a resource-investment-model. The question is, wether the influence of the ethnic origin could be mediated by the social background and parental investments. The project “Preschool education and educational careers among migrant families” supplied data on 1046 families. The analyses clearly show ethnic differences in early development. These differences persist even after controlling for the socioeconomic background, but disappear after controlling for the investments of the parents. Therefore, the family background and the investment of parents in their children’s home environment improve the developmental score of the child and explain the observed ethnic differences. Additional analyses show that among German children the social background is even more important than among Turkish children. The differential development of Turkish children is mainly stimulated by their parent’s investments.  相似文献

Abstract:  This article examines the European approach to joint venture regulation. It updates previous analysis by examining the impact of modernisation reforms on joint venture regulation in Europe. It is argued that although the changes on the whole are conducive to joint venture activity, problematic aspects of regulation were either unaddressed, or could be provoked by, the reform. In particular, the substantive and procedural divide in legal treatment of 'concentrative' and 'cooperative' joint venture arrangements continues to engender some difficulty.  相似文献

Interpersonal violence within lesbian relationships is a significant yet understudied problem. Women attending a gay pride festival in Atlanta, GA, were asked to complete a survey concerning same-sex interpersonal violence. Women who reported being in a current or previous same-sex partner relationship were included in the analyses (N = 226). Factors that occurred in the context of interpersonal violence were investigated: substance use, HIV/STI risk behaviors, barriers to reporting abuse, and attitudes inhibiting seeking of social support. In addition, the survey assessed relationship-related power dynamics. Results of multivariate analyses support the hypotheses that power imbalance and inequality when making sex-related decisions within women’s same-sex relationships are associated with interpersonal violence. Further findings suggested that a combination of factors must be considered when dealing with and reducing the risk for violence in same-sex relationships.  相似文献

At the 2021 Shanghai Cooperation Organization (SCO) summit, the Russian- and Chinese-led bloc announced the approval of Iran's longstanding bid for membership. Iran has viewed its involvement in the organization as a means of bolstering external legitimacy, fostering security-oriented regionalism, and promoting the transition toward the so-called multipolar world order. The SCO has served as a regime-preservation network by providing Iran with a source of solidarity against external pressure. Tehran's commitment to the normative order, sustained by the SCO's discourse of noninterference, sovereignty, and countering the “three evils”—terrorism, extremism, and separatism—has galvanized the organization's role as a common front against the imposition of liberal norms and challenges to regime security.  相似文献

This paper examines the participation of member states of the Caribbean Community (CARICOM) in the World Trade Organisation (WTO)’s dispute settlement system and its associated negotiations. In so doing, it highlights the dispute settlement system’s important contribution to the WTO and the need for CARICOM member states to engage more actively with this aspect of the WTO’s work. The paper concludes by articulating some of the lessons learnt from CARICOM member states’ experiences to date and offering some concrete suggestions on how the region can improve its current record of engagement.  相似文献

Often, criminal acts involving a vehicle are caught on digital video surveillance systems. While potentially useful for an investigation, the recording conditions are typically less than optimal for the extraction of key information for the identification of the perpetrator, such as a license plate. Providing the make, model and year of a questioned vehicle is a common request for examiners, to narrow the field of potential suspect vehicles. This study seeks to compare the performance of a nonpeer-reviewed make, model, and year determination between two separate groups, specifically, trained forensic image examiners and nontrained individuals. Results show that even with varied image capture conditions and quality, the trained forensic image examiners more correctly and completely identified the test group of questioned vehicles make, model, and year.  相似文献

Abstract: Modern health‐care systems in OECD countries were built around hospitals and the preferences of organized medicine and are largely focused on acute‐care services and services provided by doctors. Starting in the early 1980s, however, the professionalization in several countries of trades traditionally involved in health promotion, together with the constitution of a group of researchers in social epidemiology and the corresponding development of specialized schools and research centres, brought new actors into health policy‐making worldwide. This led to the extension of contemporary health policy beyond the post‐war bio‐medical model into population health promotion and social policy. This article describes and analyses the means (and limitations) used by Canada and Sweden for extending the action radius of health policies. Results show that national policies in health promotion beyond the health sector contributed above all to developing and legitimizing an official discourse that presents social problems as factors affecting social inequalities in health. Health promotion represented a tool for maintaining central social norms, as national governments were re‐defining their role in social policy. Sommaire: Les systèmes modernes de soins de santé dans les pays de l'OCDE ont été construits autour d'hôpitaux et des préférences de la médecine organisée et sont essentiellement axés sur les services de soins intensifs de courte durée et les services médicaux. Cependant, depuis le début des années 1980, la professionnalisation des métiers traditionnellement impliqués dans la promotion de la santé survenue dans plusieurs pays, associée à la constitution d'un groupe de chercheurs en épidémiologie sociale et le développement d'écoles et de centres de recherche spécialisés ont introduit de nouveaux acteurs dans l'élaboration de politiques en matière de santéà l'échelle mondiale. Cela a entraîné une transformation de la politique de la santé contemporaine, qui a dépassé le modèle biomédical d'après‐guerre pour s'étendre à la promotion de la santé de la population et à la politique sociale. Le présent article décrit et analyse les moyens utilisés par le Canada et la Suède pour étendre le rayon d'action des politiques de la santé et les limites auxquelles ils font face. Les résultats indiquent que les politiques nationales visant la promotion de la santé au‐delà du secteur de la santé ont contribué avant tout à développer un discours officiel qui présente les problèmes sociaux comme des facteurs ayant une incidence sur les inégalités sociales de la santé. La promotion de la santé a représenté un outil pour maintenir des normes sociales nationales, alors que les gouvernements centraux redéfinissaient leur rôle en matière de politique sociale.  相似文献
