Deoxyribonucleic acid (DNA) was isolated from a number of spongy and compact human bone tissue specimens, and the yield was estimated on a "per milligram of starting tissue" basis. DNA was, in addition, isolated from a number of corresponding blood and bone tissue specimens. Spectrophotofluorometry and ethidium bromide visualization on minigels were used to estimate the quantity and degree of degradation of DNA. The DNA from several blood-bone pairs is shown to give concordant restriction fragment length polymorphism (RFLP) typing results by two different typing protocols with five different single-locus probes. DNA from several additional blood-bone pairs is shown to give concordant results for human leucocyte antigen (HLA)-DQ alpha phenotypes following polymerase chain reaction (PCR) amplification and hybridization to specific allele-specific oligonucleotide (ASO) probes, and for the variable numbers of tandem repeats (VNTR) length polymorphisms 3' to the human apolipoprotein B (APOB) gene following PCR amplification with specific primers and analysis of the products by electrophoresis and ethidium bromide visualization. 相似文献

The Institutional Basis of Secessionist Politics: Federalism and Secession in the United States 总被引:1,自引:0,他引:1
According to the literature on secession, the most importantdeterminant of secessionist sentiment is a high level of grievanceexperienced by the would-be secessionist group. However, therationale behind using secession (as opposed to another strategy)as a grievance-amelioration strategy remains almost completelyunexplained. This article contends that the institutional settingin which political conflict and grievance are experienced playsa crucial role in whether secession is conceived of as a viableoption. This contention is tested by examining the institutionalenvironment of federalism and the role it played in secessionin the United States in 1860 and 1861. The United States wasuniquely vulnerable to secessionist pressuresas are allfederal states, potentiallybecause of institutional structuresthat gave constituent states a high level of institutional authorityand capacity; this, in turn, contributed to a discourse of states'rights that included the contested right to secede. 相似文献

The Conditional Nature of Political Risk: How Home Institutions Influence the Location of Foreign Direct Investment 下载免费PDF全文
What determines whether countries' institutions attract or deter investment? Although existing theories predict that multinational enterprises (MNEs) avoid locations where institutions cannot constrain public and private actors' opportunistic behavior, we argue host institutions' attractiveness depends on firms' home environment. Home country institutions shape firms' practices and capabilities, thus helping to determine the environments that firms are best prepared to face abroad. We test our predictions using multiple data sets at different levels of analysis: firm‐level data on MNEs' foreign subsidiaries, data on bilateral foreign direct investment (FDI) positions, and longitudinal data on bilateral FDI flows. We find that states with independent judiciaries are particularly attractive to investment from countries also possessing independent courts. Similarly, countries with low judicial independence disproportionately send FDI to countries lacking independent judiciaries. These findings' implications challenge conventional wisdom: “Good” institutions may not attract all investors, and “bad” institutions may not always deter, as current research suggests. 相似文献

From hegemonic to inclusive masculinities in English professional football: marking a cultural shift
AbstractIn this article, we conduct a generational study of measuring progress towards the inclusion of homosexuality in professional sport. We accomplish this by interviewing an openly gay football player, Anton Hysén, in the year 2017, using the precise same questions about the relationship between his homosexuality and sport that were asked of the first openly gay professional footballer in 1992, Justin Fashanu. We thus measure difference in attitude according to the 25 years that have elapsed between the interviews. Our results emphasize two themes: First, the near-total acceptance of being gay within professional football today, compared to 25 years ago; and second, the social praise that is levied upon today’s openly gay sportsmen, compared to the social stigma placed upon Fashanu. 相似文献

Relative to chronic hunger, seasonal hunger in rural and urban areas of Africa is poorly understood. This paper examines the extent and potential correlates of seasonal hunger in Malawi using panel data from 2011–2013. We find that both urban and rural households report seasonal hunger in the pre-harvest months. Certain strategies to smooth consumption, including crop storage and livestock ownership, are associated with fewer months of hunger. In addition, we find that Malawian households that experience seasonal hunger harvest their crops earlier than average – a short-term coping mechanism that can reduce the crop’s yield and nutritional value, possibly perpetuating hunger. 相似文献
