Collection of DNA for genetic profiling is a powerful means for the identification of individuals responsible for crimes and terrorist acts. Biologic hazards, such as bacteria, endospores, toxins, and viruses, could contaminate sites of terrorist activities and thus could be present in samples collected for profiling. The fate of these hazards during DNA isolation has not been thoroughly examined. Our goals were to determine whether the DNA extraction process used by the Royal Canadian Mounted Police eliminates or neutralizes these agents and if not, to establish methods that render samples safe without compromising the human DNA. Our results show that bacteria, viruses, and toxins were reduced to undetectable levels during DNA extraction, but endospores remained viable. Filtration of samples after DNA isolation eliminated viable spores from the samples but left DNA intact. We also demonstrated that contamination of samples with some bacteria, endospores, and toxins for longer than 1 h compromised the ability to complete genetic profiling. 相似文献

We analyze the relation between naturalization, mobility, and security through 50 in-depth interviews with migrants of different origins living in two Italian regions. We show how migrants pursue naturalization both to protect themselves against bureaucracy and deportation and to move to a third country. The second migration is motivated by improving one's conditions, forced by the economic crisis, or completes the original migratory project once a strong passport is obtained. We argue that citizenship is not essentially linked to either stability or mobility and that mobility should be understood as neither exceptional nor always chosen. 相似文献

Gender Differences in Rates of Depressive Symptoms Among Low-Income,Urban, African American Youth: A Test of Two Mediational Hypotheses 总被引:3,自引:0,他引:3
Grant Kathryn E. Lyons Aoife L. Finkelstein Jo-Ann S. Conway Kathryn M. Reynolds Linda K. O'Koon Jeffrey H. Waitkoff Gregory R. Hicks Kira J. 《Journal of youth and adolescence》2004,33(6):523-533
The present study tested for gender differences in depressive symptoms in a sample of 622 low-income, urban, African American adolescents. Results indicate that adolescent girls in this sample were significantly more likely to endorse depressive symptoms than were boys. To examine possible explanations for this gender difference, 2 variables were tested as mediators of the relation between gender and depressive symptoms: (1) interpersonal stressors and (2) ruminative coping. Results indicate that ruminative coping, but not interpersonal stressors, mediated the relation between gender and depressive symptoms in this sample. Possible explanations for these findings, in light of the common and unique experiences of low-income, urban youth of color, are explored. 相似文献

Since the escalation of the Syrian conflict and refugee crisis in 2011, almost a fifth of Syrian Armenians in Syria have fled to Armenia. Most of them are descendants of the Armenian Genocide (1915) victims, who found shelter in Syria a century ago. Contrary to expectations on ethnic repatriation, their displacement and attachment to Syria emerge. The study assesses this peculiar case of the origin and return of a ‘traditionally diasporic’ community by combining models offered by diaspora studies with analysis of qualitative research on Syrian Armenian returnees who fled war-torn Syria. Continuing on the pathway initiated with the ‘Great Repatriation’ of Armenian diasporans to Soviet Armenia of 1946, the return to Armenia is a prolonged trajectory of diasporic displacement. Syrian Armenians returning to Armenia experience a conflict-generated diaspora of diaspora in the supposed homeland of Armenia. Explanations include the dissociation between the imagined Armenian homeland and the legally constituted one in present-day Armenia, and between the latter and the motherland of Syria. This challenges the essentialist account of the Armenian diaspora and, ultimately, the hypothesis surrounding Syrian Armenian marginalization and gradual ‘exit strategy’ in Syrian society. 相似文献

New entrepreneurial ventures may represent a viable and effective mechanism to transform academic knowledge into regional economic growth. We test this notion for the Italian provinces between 2001 and 2006. We evaluate three outputs of academic activities: teaching, research and intellectual property rights activities. New ventures may be able to transform the mentioned outputs into improved economic performance. The findings show that the effects of academic outputs on provincial economic growth (all sectors) are appreciable when they are associated with sustained entrepreneurial activities in the province. It suggests that academic inquiry may provide new ventures with valuable commercial opportunities overseen by established companies. 相似文献

The paper draws on recent research on the economics of prostitution focussing on the role of stigma in shaping the interaction
between demand and supply and the resulting sub-markets in which this activity is typically organised. Here we extend the
framework to consider the role of reputation and stigma in determining policy decisions regarding the regulation of prostitution
and show how sub-optimal outcomes (from the point of view of the welfare of sex workers) may prevail. 相似文献

The relationship between perceived maternal control and depression was examined in 111 urban adolescent girls seeking psychological services at an outpatient mental health center in the Midwest. This study sought to clarify inconsistent findings in earlier research linking parental control and adolescent depression by examining urban girls with mental health problems and by testing ethnic background as a moderator of the general relationship. Data were collected using self-administered questionnaires of adolescent girls' depressive symptoms, and perceptions of their mothers' parenting styles. Analyses did not detect a significant association between maternal control and depression in the combined sample of adolescent girls; however, findings were moderated by the ethnicity of the girls. Once ethnicity was included, no relation between control and depression was found for Caucasian and Latina girls, but high control was linked to less depression among African American girls. These findings highlight the importance of ethnicity and gender in child rearing and adolescent depression and stress the need for more culturally sensitive conceptualizations of depression 相似文献

Abstract. During the investigations into political corruption in Italy, judges emerged in the eyes of the public as the 'heroes' of a peaceful revolution against the 'villainous' politicians. The established explanation for the active role of the judiciary against corruption stresses the unusual degree of independence of Italian judges. Without denying the importance of this institutional variable, analysis of the interactions between politicians and judges in the history of the Italian Republic allows one to discuss the role of other two important variables: the informal networking between politicians and judges, and the professional culture of the magistracy. The three sets of variables are in fact used to explain two different strategies adopted by Italian judges in their interaction with the political system: a strategy of 'role substitution', acccording to which some judges act as a surrogate power for the protection of the citizens against corrupt politicians, and a 'collusive strategy', consisting of various levels of hidden exchanges between judges and politicians. This article is based on an examination of judicial documents relating to 40 episodes of political corruption, in–depth interviews with experts, reports of relevant Parliamentary Inquiry Commissions, requests for indictment of Members of Parliament, official statistics and the daily and weekly press. 相似文献

Since 1992, administrative reform has become a major theme on the Italian political agenda. This article examines the pressures leading to reform under the Ciampi government (April 1993‐May 1994). It focuses, first, on the directions to be taken by reform that were identified and, second, on their implementation. Also considered are the obstacles to reform found in the political and administrative systems. The limits to the reform and its legacy illustrate the more general problems of the Italian legal and constitutional order. 相似文献
