Nanotechnology: The Challenge of Regulating Known Unknowns 总被引:3,自引:0,他引:3
Media reports of the health hazards posed by nano-sized particles (NSPs) have turned a white hot spotlight on the risks of nanotechnology. Worried about the risks posed to workers producing nano-materials, the Washington Post has labeled nanotechnology a "seat-of-the-pants occupational health experiment." This article examines our emerging knowledge base about the hazards of two types of exposure: inhalation of NSPs and topical application of products containing NSPs. It argues that a clear-eyed evaluation of the benefits and risks of nanotechnology is made extremely difficult by the marriage of a complex science with a venture capitalist-like hype. It then suggests that, absent additional statutory authority, governmental regulators cannot readily address the risks posed by these products. This regulatory inaction leaves a significant role for the private insurance market, a role that regulators should support in tangible ways outlined in the article. 相似文献

Purpose
Disproportionate minority contact during traffic stops has been a consistent source of commentary and study in recent years. While various theoretical perspectives have been employed to explain these empirical findings, the differential offending hypotheses has been largely ignored as a viable alternative explanation. Building on existing empirical evidence regarding criminal offending patterns and driving patterns, we examined the veracity of this explanation using data from an observational study of urban driving behavior.Methods
Data were collected using an observational methodology in an urban environment. These data were then used to estimate various regression models and test the differential offending hypothesis.Results
Analytic models indicated that Black drivers speed more frequently and engage in more severe speeding compared to White drivers, net of controls.Conclusions
The findings suggest that citizen risk for specific police behavior is partially attributable to differential behavior prior to the encounter. These results mirror the findings of previous research in other geographic locations using different methodologies; thus, contributing to the conclusion that understanding officer decision-making and behavior requires consideration of other factors beyond a citizen's race. 相似文献45.

Helping women victimized by intimate partner violence (IPV) is a challenge, particularly when the women belong to diverse ethnic groups. The objective of our study was to collect information on perceptions of coping with IPV from the perspective of a specific immigrant group of women. Sixty-three women from the Tamil community in Toronto representing different generations and experiences of IPV were interviewed in focus group settings about their views of coping with IPV. Study findings suggested that their views were deeply embedded in their sociocultural context and influenced by the gender-role expectations from the community. The women showed a marked preference for “passive” modes of coping rather than “active.” Study findings have implications for the development of alternative approaches to helping ethnically diverse women deal with IPV. 相似文献

Judges are prone to error and misapprehension when they are verifying the facts of a legal case. We analyze the significance and scope of accurate court decisions and judicial error for labor contracting and identify the implications of these concepts on behavioral incentives and market outcomes. We find that imperfect judicial state verification and the diverging beliefs on a court ruling reduce the efficiency of contingent labor contracts and make them less effective in stipulating sufficient incentives for compliance. If increasing court accuracy in general is not feasible, the courts (and the legislator) should primarily mitigate type I errors. The common reversal of the burden of proof to the employer in labor laws reflects these insights. The model also indicates that the ability of judges to verify facts is a prerequisite for efficient law-making and contributes significantly to the economic role of courts. 相似文献

This study tested the hypothesis that investments in early childhood schools have short-term crime reducing effects in neighborhoods. Time series data from the city of Tulsa, Oklahoma, were analyzed to evaluate the effects of an early childhood school built in the neighborhood of Kendall-Whittier as part of a larger neighborhood revitalization plan, on violent and property crime. Results revealed that after controlling for city-wide crime trends and monthly fluctuations, violent crime declined significantly in Kendall-Whittier. Further analysis indicated that the possible crime-reducing effects of school investments on violent crime spread beyond Kendall-Whittier, and no displacement was found. The results for property crime were mixed. The study demonstrates the use of clustering analysis, a useful tool in neighborhood-level research to identify comparison neighborhoods. The findings shed light on the possibility that investments in early childhood schools can yield results in a shorter term than anticipated, making them a desirable component of urban revitalization. 相似文献

Bullet embolism is a relatively unusual complication of gunshot wounds. Embolism to the right atrium comprises <5% of all reported intravascular bullet emboli. We report an additional case of bullet embolus to the right atrium of a 0.38-caliber bullet following a gunshot wound to the chest. The intracardiac bullet was recognized radiologically on presentation, but the patient was hemodynamically stable and managed conservatively, with the bullet left in place. The missile remained within the heart without clinical significance for several years and was recovered from the right atrium only at the time of autopsy. To the best of our knowledge, this is the first documented case of a 0.38-caliber bullet which embolized to the right atrium and remained inconsequential for an extended period of time. 相似文献
