We identified and characterized 14 novel short-tandem-repeats (STRs) on the Y chromosome and typed them in two samples, a globally diverse panel of 73 cell lines, and 148 individuals from a European–American population. These Y-STRs include eight tetranucleotide repeats (DYS449, DYS453, DYS454, DYS455, DYS456, DYS458, DYS459, and DYS464), five pentanucleotide repeats (DYS446, DYS447, DYS450, DYS452, and DYS463), and one hexanucleotide repeat (DYS448). Sequence data were obtained to designate a repeat number nomenclature. The gene diversities of an additional 22 Y-STRs, including the most commonly used in forensic databases, were directly compared in the cell line DNAs. Six of the 10 most polymorphic markers include the newly identified Y-STRs. Furthermore, these novel Y-STRs greatly improved the resolution of paternal lineages, above the level obtained with commonly used Y-STRs, in the European–American population. 相似文献

A summary of a panel discussion by seven participants in the Federal Communications Commission's cable television rulemaking. Analysis of the potential impact of cable on over-the-air broadcasting was a prominent part of the rulemaking; but did it make any difference in the outcome? The panelists discussed how analysis was used and what effect it had on the rules finally adopted. It was agreed that analysis was used, not as a tool in the hands of decisionmakers, but rather as a weapon in the hands of the contending parties. Nevertheless, analysis had an important effect by strengthening the FCC's perceptions of cable's possible benefits and damping fears of its offsetting harms, resulting in a compromise outcome that is more encouraging to cable growth than it otherwise would have been. 相似文献

There is a dearth of published research on the role of intergroup contact on urban US ethnic minority children’s and adolescents’
evaluations of racial exclusion. The current investigation examined these issues in a sample of low-income minority 4th, 7th,
and 10th grade (N = 129, 60% female) African American and Latino/a students attending predominately racial and ethnic minority US urban public
schools. Using individual interviews, participants were presented with scenarios depicting three contexts of interracial peer
exclusion (lunch at school, a sleepover party, and a school dance). Novel findings were that intergroup contact was significantly
related to low-income urban ethnic minority youth’s evaluations of the wrongfulness of race-based exclusion and their awareness
of the use of stereotypes to justify racial exclusion. Further, significant interactions involving intergroup contact, context,
age, and gender were also found. Findings illustrated the importance of intergroup contact for ethnic minority students and
the complexity of ethnic minority children’s and adolescents’ judgments and decision-making about interracial peer exclusion. 相似文献

Korean small businesses have come a long way as sources of industrial power more important than heretofore credited. The nation's undemocratic dirigisme had largely slighted small businesses to the country's disadvantage. Although the government's policy bias against them started to change in the early 1980s, its support of them remained less than fully-fledged. Despite tough socio-economic conditions, however, both the first and second generation small entrepreneurs have strived to prove their self-worth as viable business enterprises and constantly—and increasingly over time—contributed to the incremental improvement of the economy. By shedding light on the little-known motivations, perceptions, and performances of the small business people, this article offers a more balanced and nuanced account of the past and present state of small businesses in the country, which provides a tentative basis for considering alternative vision for future development. 相似文献

Two multiplex polymerase chain reaction (PCR) systems (Midiplex and Miniplex) were developed for the amplification of the mitochondrial DNA (mtDNA) control region, and the efficiencies of the multiplexes for amplifying degraded DNA were validated using old skeletal remains. The Midiplex system consisted of two multiplex PCRs to amplify six overlapping amplicons ranging in length from 227 to 267 bp. The Miniplex system consisted of three multiplex PCRs to amplify 10 overlapping short amplicons ranging in length from 142 to 185 bp. Most mtDNA control region sequences of several 60‐year‐old and 400–500‐year‐old skeletal remains were successfully obtained using both PCR systems and consistent with those previously obtained by monoplex amplification. The multiplex system consisting of smaller amplicons is effective for mtDNA sequence analyses of ancient and forensic degraded samples, saving time, cost, and the amount of DNA sample consumed during analysis. 相似文献

This paper comparatively examines diverse responses from three major actors in the global political economy (the state, civil society, international financial institutions) to the Asian financial crisis of 1997 and the current eurozone crisis. First, it analyses conditional lending policies of international financial institutions (IFIs) such as the International Monetary Fund toward countries in fiscal distress. It then critically examines how the lending policies engendered social tensions and conflicts as austerity measures such as cuts to social welfare programmes hit hard on the populace. Examining how the state and civil society in Asia reacted to and, as a result of contentious state–civil society interactions, altered the policies of IFIs, the paper draws lessons from the Asian financial crisis for the European Union and puts forwards alternative policy suggestions. 相似文献
