A clear positive case for anabolic steroids doping was confounded by alleged urine tampering during doping control procedures. Review of the chain of custody showed no flaws, but nevertheless the athlete was adamant that the urine sample should be analyzed for DNA in order to support her contention that she was not the donor of the sample. The results obtained showed that the urine sample that scored positive for steroids contained nuclear DNA that could not be matched to the DNA obtained from the athlete's blood. On the other hand, the same urine sample contained mitochondrial DNA whose nucleotide sequences spanning the hyper variable regions HV1 and HV2 proved to be identical to those determined in mitochondrial DNA amplified from the athlete's blood. The occurrence of an extraneous genotype is compatible with exogenous nuclear DNA admixture to the athlete's urine. Alternatively, taking in consideration the mitochondrial DNA, we could not exclude that a sibling or a maternal relative of the athlete could have acted as a donor of the urine utilized for doping control and DNA analysis. Both situations point to possible tampering of the urine by the athlete. Adjudication at CAS maintained previous national and international federation decision that there was no proof of a chain of custody flaw to justify the athlete's allegation of urine substitution after collection. 相似文献

Fiscal policy and reelection in Brazilian municipalities 总被引:1,自引:0,他引:1
This paper uses a new panel of more than 2,000 Brazilian municipalities over 13 years to analyze the influence of public expenditures on the probability of mayors’ reelection. We examine Brazilian municipal elections from 1988 to 2000 using a logit fixed-effects model. The results suggest that mayors who spend more during their terms of office increase the probability of their own reelection or of a successor of the same political party. In particular, higher capital spending over the years preceding elections and current expenditures in election years are beneficial to Brazilian incumbent mayors. 相似文献

This study explores the prevalence and correlates of past-year physical violence against women in slum and nonslum areas of urban Bangladesh. The authors use multivariate logistic regression to analyze data from the 2006 Urban Health Survey, a population-based survey of 9,122 currently married women aged between 15 and 49 who were selected using a multistage cluster sampling design. The prevalence of reported past-year physical spousal violence is 31%. Prevalence of past-year physical spousal violence is higher in slums (35%) than in nonslums (20%). Slapping/arm-twisting and pushing/shaking/ throwing something at the women are the most commonly reported acts of physical abuse. Multivariate analysis shows that the risk of physical spousal abuse is lower among older women, women with post-primary education, and those belonging to rich households and women whose husbands considered their opinion in decision making. Women are at higher risk of abuse if they had many children, believe that married woman should work if the husband is not making enough money, and approve wife-beating norms. This study serves to confirm the commonness of physical spousal abuse in urban Bangladesh, demonstrating the seriousness of this multifaceted phenomenon as a social and public health issue. The present findings suggest the need for comprehensive prevention and intervention strategies that capitalize on the interplay of individual and sociocultural factors that cause physical spousal violence. Our study adds to a growing literature documenting domestic violence against women in urban areas of developing south Asian nations. 相似文献

Over the past decades, university-industry relationships have become an important subject due to the essential role played by technological progress in the economic development of countries. From a theoretical point of view, several studies have shown the close relationship between investments in research and innovative activities of universities and the economic growth of specific territories. Indeed, the strong linkages between universities and a country’s production system encourage the process of technology transfer and the commercial use of the research results. For this reason, the European Union has implemented a series of measures to promote the adoption of research findings in the real economic and social context, strengthening the linkages between universities, industries and government. As a starting point for enhancing this link, specific mechanisms have been devised by universities. In particular, technology transfer offices (TTOs) have been created to stimulate and encourage the dissemination of the research outcomes, translate them into practise, and facilitate their interrelations with the other two agents of the innovation systems: industries and government. Within this context, the present paper aims to gain knowledge on the determinants of spin-off creation in Italy with special attention to the role played by university TTOs. Specifically, an econometric probability model has been built merging the extant literature into four distinct strands. The analysis, based on the NetVal indicators and primary data survey, has allowed us to assess the Italian experience at an aggregate and disaggregate level. 相似文献

The negative adaptation hypothesis states that Black employees, but not White employees, have psychologically adapted to the
occurrence of interpersonal mistreatment in organizations because they experience more negative events across different domains
of social life than Whites. Consequently, Blacks react less strongly to the same level of actual interpersonal mistreatment
compared to Whites. The authors applied this prediction to the relationship between non-contingent punishment and organizational
citizenship behaviors (OCB). As expected, in a field study among 456 manufacturing plant workers, the relationship between
non-contingent punishment and supervisory-rated OCB was negative and significant for Whites, but not for Blacks. Implications
for the study of race, interpersonal mistreatment, and the perpetuation of racial inequalities in organizations are discussed.
