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

I am concerned here with the political responses of peasants on the social and economic margin and of agricultural labourers. The argument is that there is in India a vital and dynamic peasant activism happening at many levels of social and economic interest including among the rural poor. I want to understand these phenomena in Indian terms and in local terms, in other words, what is happening in the fields and villages where most Indians live. This raises the fundamental issue of the language or idiom in which agrarian politics, that is the politics of dissent, is expressed and the equally important question of who is listening and what is or is not being done in response. I develop these ideas around the experience of the Indian People's Front in the last decade, specifically in Bihar, while focussing on the arena of electoral politics which the IPF entered seriously in 1989. 相似文献

This paper develops a metaphor that shows academia as a temple of science where acolytes and priests devote themselves to building and developing an arcane lore that supports their faith. Though a somewhat strained metaphor, its heuristic value will become clearer when illustrated by lessons drawn from the sociology of knowledge. Through these lessons, I will attempt to demonstrate that the university setting has inexorably influenced the theories that have developed there, particularly in contributing to the perception of a gap between theory and practice that an applied, problem-solving field such as public administration can ill afford. 相似文献

Previous studies suggest cardiovascular pathologists are less accurate than noncardiovascular pathologists (e.g., clinical pathologists) in estimating the degree of coronary artery stenosis. To further investigate the effect of training on accurate estimation of coronary artery stenosis, we designed a study to compare the accuracy of estimates made by forensic pathologists versus medical students. Six forensic pathologists and twelve medical students each independently examined 24 images of coronary artery cross sections and gave an estimate of the degree of stenosis. When comparing all 24 images, the forensic pathologists had a median difference between the estimated percentage of stenosis and actual percentage of stenosis of −12.380 and the medical students had a median difference of −16.50 (p-value of 0.08542). In estimating the percentage of stenosis, training in forensic pathology does not guarantee significantly improved accuracy compared with medical students. Our study showed no consistent statistically significant difference between estimates given by forensic pathologists and by medical students. 相似文献

Why do political parties in parliamentary systems undertake actions, such as joining a coalition government, that will entail significant costs for their members in subsequent elections? Recent research points to the incentive structures faced by differentially positioned members of a parliamentary party: unlike backbenchers, MPs who hold a ministerial portfolio can use the prerequisites of executive office to shield themselves from the costs of governance. This article tests the theory of executive particularism by examining the electoral fortunes of government ministers in India. Sitting government ministers are found to outperform other candidates; however, tests of causality fail to demonstrate that holding a ministerial portfolio causes this electoral benefit. Instead, it appears that a candidate’s electoral performance enhances the likelihood of being granted a ministerial portfolio in the first place. This finding raises questions about the generalizability of claims that party elites can use ministerial office to shield themselves from the costs of governing. 相似文献
