Mongolia is not a hapless object on which the great powers may act at will. Like other small states existing on the periphery of great powers, Mongolia has—and does exercise—political agency. Its policies and actions affect not only the bilateral relationship it has with each of the greater powers, but—as an outgrowth of those bilateral relations—it also exerts some influence on the relationship that the great powers, in turn, have with each other. “… you know as well as we do that right, as the world goes, is only in question between equals in power, while the strong do what they can and the weak suffer what they must.”1 相似文献

Variability in the blood–breath ratio (BBR) of alcohol is important, because it relates a measurement of the blood-alcohol concentration (BAC) with the co-existing breath-alcohol concentration (BrAC). The BBR is also used to establish the statutory BrAC limit for driving from the existing statutory BAC limits in different countries. The in-vivo BBR depends on a host of analytical, sampling and physiological factors, including subject demographics, time after end of drinking (rising or falling BAC), the nature of the blood draw (whether venous or arterial) and the subject’s breathing pattern prior to exhalation into the breath analyzer. The results from a controlled drinking study involving healthy volunteers (85 men and 15 women) from three ethnic groups (Caucasians, Hispanics and African Americans) were used to evaluate various factors influencing the BBR. Ethanol in breath was determined with a quantitative infrared analyzer (Intoxilyzer 8000) and BAC was determined by headspace gas chromatography (HS-GC). The BAC and BrAC were highly correlated (r = 0.948) and the BBR in the post-absorptive state was 2 382 ± 119 (mean ± SD). The BBR did not depend on gender (female: 2 396 ± 101 and male: 2 380 ± 123, P > 0.05) nor on racial group (Caucasians 2 398 ± 124, African Americans 2 344 ± 119 and Hispanics 2 364 ± 104, P > 0.05). The BBR was lower in subjects with higher breath- and body-temperatures (P < 0.05) and it also decreased with longer exhalation times into the breath-analyzer (P < 0.001). In the post-absorptive state, none of the 100 subjects had a BBR of less than 2 100:1. 相似文献

The authors explored the characteristics of individuals that affect their attitudes toward restorative justice-—in which offenders, victims, and communities meet to redress the damage the offence had caused. Across three studies, participants completed questionnaires that assessed whether they believe that people in general, or offenders in particular, can change fundamentally as well as attitudes toward restorative justice, rehabilitation, and punishment. In one study, the questionnaire also included measures of social dominance orientation, goal orientation, and future clarity. Generally, participants who believed that offenders can change fundamentally were more likely to agree to participate in restorative justice meetings and endorse rehabilitation over punishment. Yet, the belief that individuals in general can change fundamentally was not significantly associated with these attitudes toward alternative responses to crime. Social dominance orientation was inversely, and a learning orientation and future clarity were positively, associated with this belief that offenders can change. Thus, interventions that diminish inequality in income, privileges, and influence—and thus curb a social dominance orientation—may foster an openness toward restorative justice. Initiatives that continually reward people who gradually develop their expertise, and thus promote a learning orientation, should also foster this openness toward alternatives to custodial sentences. 相似文献

The present article presents the results of a qualitative study whose purpose was to compare the structure and operation of the programs for intellectual property management and technology transfer, and the mechanisms through which to foster entrepreneurship, in five high-profile research institutions across the Americas. The institutions of focus included Stanford University and the University of California, Davis in the United States; the Universidad Católica and the Universidad de Concepción in Chile; and the National Scientific and Technical Research Council in Argentina. The purpose of the study was to elucidate commonalities and differences among these institutions with respect to their technology transfer practices, and to distill methodologies that could be used to establish or refine technology transfer offices in American regions. Research revealed common goals and core activities, shared and implemented in similar ways among all five institutions. However, the analysis also identified divergent areas within the structure and operation of the various technology transfer programs, representing significant differences between the five institutions. 相似文献

The UK's second nationwide referendum, held in May 2011, offers rich opportunities for analysing the dynamics of a referendum campaign. The articles gathered together in this symposium address three themes. The first concerns the determinants and dynamics of public opinion during a referendum campaign, the second relates to the potential for interaction between the referendum and simultaneous elections, and the third focuses on coverage of the referendum in the media. Following a brief outline of the background to the referendum, this paper introduces the contribution that each article makes to these themes. 相似文献
