Quality assurance samples submitted from the NCSBI as part of a contract with TBTG to outsource DNA Database samples showed unexpected discrepancies for the locus D16S539 when all other loci yielded identical results. Discrepancies observed included allele drop out and an imbalance in sister alleles with samples returned from TBTG. This led to a comprehensive review of the technical procedures used between the two laboratories to determine the cause of the discrepancies noted for the locus D16S539, since both laboratories were using the PowerPlex 1.1 typing kit from the Promega Corporation. The NCSBI and the TBTG utilize different extraction methods (organic extraction vs. FTA) and amplification conditions (AmpliTaq vs AmpliTaq Gold), respectively, so the exact cause of discrepancy observed was not immediately apparent. Experiments at the NCSBI associated the observed allele drop out and the imbalance of the sister alleles with the use of AmpliTaq Gold and a hot start procedure. Sequencing data revealed that a point mutation resides on the D16S539 primer-binding site that reaches polymorphic levels in African-American populations. This led to the development of a degenerate primer by the Promega Corporation to detect "missing" alleles when AmpliTaq Gold is used. The degenerate primer was then thoroughly tested to show its efficacy in detecting the "true" D16S539 profile when used. 相似文献

Recent research has highlighted the role of culture in emerging adulthood (age between 18 and 25 years). However, most studies have examined majority cultures (e.g., China) as well as subcultures (e.g., American ethnic minorities). Thus, work on other aspects of culture such as religion is needed given the emerging evidence that it may have an impact on development. This study explored the role of religious culture in the emerging adulthood of college students. Participants were 445 undergraduates (ages 18–20 years) from institutions that were Catholic (31 males, 89 females), Mormon (48 males, 200 females), and public (21 males, 56 females). Results found religious differences in (a) the criteria young people deemed necessary for adulthood, (b) the extent to which emerging adults felt they had achieved these criteria, (c) various aspects of spirituality including practices and beliefs, and (d) the behaviors in which emerging adults engage.Portions of this study were presented at the biennial meeting of the Society for Research in Adolescence, Baltimore, Maryland, in March 2004.Assistant Professor of Psychology at Loyola College in Maryland.

Traditional theories of democracy suggest that political representation of excluded groups can reduce their incentives to engage in conflict and lead to lower violence. However, this argument ignores the response of established elites when (1) their interests are threatened by the policy stance of new political actors and (2) elites have a comparative advantage in the exercise of violence. Using a regression discontinuity approach, we show that the narrow election of previously excluded left‐wing parties to local executive office in Colombia results in a one standard deviation increase in violent events by right‐wing paramilitaries. We interpret this surge in violence as a reaction of traditional elites to offset the increase in outsiders' access to formal political power. Consistent with this interpretation, we find that violence by left‐wing guerrillas and other actors is unaffected and that violence is not influenced by the victory of right‐wing or other new parties in close elections. 相似文献

Water privatization battles and their aftermath in seven Latin American, African, and Asian countries feature diverse and often complementary forms of action by unions, popular movements, neighbourhood associations, and non-governmental organizations (NGOs). NGOs cooperate with popular movements for water rights more than the literature would suggest, and after mobilizations against privatization, activists have had some success maintaining pressure for better service to poor neighbourhoods through advocacy and local self-provision arrangements. Public employees’ unions play important roles in water policy coalitions, often practising a distinctive form of social movement unionism. These experiences argue for a more flexible understanding of categories and organizational forms in civil society. 相似文献

From Peasant to Entrepreneur: the Survival of the Family Farm in Italy, by Anna Bull and Paul Corner. Oxford: Berg, 1993. Pp. ix + 174. £29.95. ISBN 0 85496 309 X. Bull and Corner's historical study of the development of the ‘pluriactive’ rural household and its impact on the structure of industry in one region of Italy might go unnoticed by those concerned with rural change in other parts of the world. However, the clear similarities between the experience they describe and contemporaneous developments in Japan suggest the possibility of an alternative pattern of agriculture/industry relations over the course of industrialisation in economies where the small‐scale, multi‐functional, rural household prevails. 相似文献

Many countries now operate state-funded international broadcasters, communicating directly with foreign publics to promote a variety of foreign policy goals. RT (formerly known as Russia Today) is currently one of the most prominent broadcasters in a crowded field. What is RT’s strategy, the size of its audience, and the effectiveness of its broadcasts in implementing its strategy? To answer these questions, we explore a case study of RT’s YouTube programming utilizing a new dataset of 70,220 video titles spanning the 2 years from February 2015 through January 2017. RT’s three-prong strategy focuses attention on strategic groups outside the West, including Arabic, Russian, and Spanish speakers, circumvents local media in target countries to promote Kremlin aims, and spreads a positive image of Russian accomplishments, particularly in Syria, which it considers a foreign policy success. The data presented here show that RT’s strategy is only partially successful since it underperforms among Arabic speakers, its main target, while doing relatively better among Russian, global English, and Spanish audiences. 相似文献

This article argues against a common-sense logic that money can assist in socialist transformation, espouses a non-market ecosocialist position and urges greater clarity in associated discourse. Analyses of capitalist operations show that growth is not simply a characteristic tendency of capitalism but rather an essential outgrowth of its deficiencies. Marx identified these deficiencies, indicating that the end of capitalism was an end to money, that is, exchange value. Money is not a tool but evolves as a code of conduct to structure social relationships that reproduce inequity, competition, distrust and alienation. Indeed, the existence of capitalists and capitalism without money is inconceivable and impossible in practice. Money refusal and the development and defence of fair non-monetary forms of livelihood continuously critique capital and demonstrate alternative (or at least “hybrid”) socialist forms. Contemporary anti-capitalists have developed constructive skills to move beyond money and capitalism in their practical development of “green materialism.” However, a wide-ranging discourse remains to be had on moving beyond money sooner rather than later. The final section of this paper sketches a non-market ecosocialist vision. 相似文献

Trust is important to the institutions that make societies successful. Globally, Indigenous peoples are actively building institutions for self‐governance, but there remains little empirical work on trust in this context. To address this gap, we use a mixed methods approach to explore three levels of trust among individual members from three related, but politically distinct First Nations (Indigenous peoples) in British Columbia, Canada. British Columbia offers a unique and dynamic context to explore trust and its relationship with the diverse institutional choices among First Nations. Survey results show that trust is low among respondents and individual variables predictive of trust in mainstream contexts, like education and employment, are not determinative. However, interpersonal trust and political trust were highest in the First Nation most active in institution building, and who linked this with a cultural revitalization narrative. Interviews suggested a bidirectional relationship between individual and collective drivers of trust in this context. 相似文献
