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

China stands as a paradigmatic sign of deep angst for the United States in late stage capitalism, a menacing spectre of foreignness and otherness that organises Western popular anxieties at a time where nothing is fixed within international markets. Focusing on the so called “currency wars” debate that erupted in the early twenty-first century, when the PRC was accused of devaluating its currency, this article contends that PRC’s representation as a prime currency manipulator and cheater can be conceptualised through what I am calling monetary Orientalism or the ways imperialising thoughts circulate around monetary flows in relation to a rising Asiatic superpower. This framework serves as a prime lens for situating US nationalist sentiment and its sense of an exceptional global self against what it perceives as a global other. 相似文献

Public management networks (PMNs) continue to proliferate as governance becomes more complex, and so does the need to hold them accountable. Agency and collaboration theories provide a solid foundation, but additional constructs are necessary to adapt to this dynamic era. Building from Bovens et al. (2008), the authors offer an ecological framework of third-party accountability that incorporates a number of prominent accountability theories under the same construct. Employing a mixed-methods research design that examines eight local PMNs in the Chicago region, the study finds that an exemplar accountability mechanism—additional cost monitoring—occurs more often in situations predicted by the framework. Additionally, qualitative interviews of network participants suggest that cost structures can differ by network type, which is verified quantitatively. 相似文献

Gottfredson and Hirschi’s General Theory of Crime (GTC) has been one of the most cited and tested theories in criminology. It posits to be in effect transcultural in its application and relevant for any norm-violating behaviors. As most empirical work has been completed in English speaking countries, the current study tested some of the main theoretical postulates in a sample of 214 Argentinean male adolescents, both offenders and non-offenders. More specifically, it tested the relationships between parental practices, self-control, criminal opportunities, and deviance. Findings provide evidence that offenders reported more deviant behaviors and more risk factors than non-offenders. They also provide partial empirical support for the main theoretical propositions. Maternal closeness, support. and monitoring had different effects on self-control and on deviance; both low self-control and opportunities had direct effects of deviant behaviors. Theoretical, research, and practical implications of study findings are discussed. 相似文献

This study used data from a sample of 6th to 12th grade students (N = 48,641, 51% female), nested in 192 schools, to determine if the influence of family-based protective factors varied across
different school contexts. Hierarchical logistic regression models were used to examine the effects of individual-level family
protective factors, relative to school-level aggregates of the same factors, on recent (past 30 days) use of cigarettes, alcohol,
and marijuana. Cross-level interactions indicated that the effect of the student’s level of family protection, relative to
other students in their school, differed depending on the aggregated school level of family protection. The results suggested
that the benefit of belonging to a well-functioning family was more influential for students attending schools characterized
by higher-than-average aggregated levels of protection compared to students attending schools of lower-than-average protection.
Thus, family-level factors offered less protection for students in relatively high-risk school contexts. These results were
consistent with a protective–reactive interaction and suggest that a thorough understanding of adolescent substance use must
consider the complex interplay among adolescents, their families, and their social environments. 相似文献

Baumgartner and Jones (1993) showed how radically new policies emerge on government agendas as a consequence of exogenous shocks to policy subsystems displacing privileged interests. But how do these policies evolve post-punctuation? In this paper, we present three different models of policy change. Policies may revert to the old status quo if displaced interests re-assert themselves, or they may be “locked-in” by new interests now reaping the benefits. Alternatively, they may incrementally change as lawmakers “learn” how to better meet target population needs, particularly by witnessing how other jurisdictions address similar problems. We test these models with data on change in state charter schools laws over time. We find that whether old status quos are overthrow, and the fate of charter policies when they are enacted, is influenced more by competing political interests, especially interest groups, than elite and public perceptions of broad systemic crises. Yet, we also find that changing demands on the state and learning from the successes and failures of neighboring states also play significant roles. 相似文献
