Wounds inflicted by high velocity, center-fire rifles firing hunting ammunition are radically different from wounds caused by handguns or .22 rim-fire rifles. Injuries from pistol or .22 rim-fire bullets are confined to tissue and organs directly in the wound track. In contrast, high velocity rifle bullets can injure structures without actually contacting them. This is due to the temporary cavity produced by such missiles with the resultant shock waves having pressures of up to 200 atmospheres (20 MPa). Organs struck by such high velocity rifle bullets may undergo partial or complete disintegration. Hunting ammunition, as it passes through the body, tends to shed fragments of lead from its core, producing a characteristic snowstorm picture on X-ray. The maximum range at which powder tattooing of the skin occurs from center-fire rifles depends on the physical form of smokeless powder used as propellant. In a test with a 30-30 rifle, cartridges loaded with ball powder produced powder tattooing out to a range of 30 in. (76 cm), while similar cartridges, loaded with the traditional cylindrical powder, produced tattooing out to only 12 in. (30 cm) of range.  相似文献

In this paper, we analyze the tax compliance behavior of U.S. taxpayers by using a 1979 data set that combines information from a random sample of individual tax returns, each of which has been thoroughly audited, IRS administrative records, and sociodemographic data from the Census. We find evidence that both audits and tax code provisions affect compliance. However, the effects are significant for only low-and high-income groups. Interestingly, work on the underground economy also suggests that it is these two groups that are least compliant. Our results for audits suggest that the ripple or general deterrent effect of audits may be substantially larger than the direct revenue yield of audits for high-income taxpayers. Our results for allowable subtractions from income imply that the 1986 Tax Reform Act changes that lowered allowable subtractions may have procompliance effects.  相似文献

Four hundred and fiftynine students from 20 different high school classrooms in Michigan participated in focus group discussions about the character strengths included in the Values in Action Classification. Students were interested in the subject of good character and able to discuss with candor and sophistication instances of each strength. They were especially drawn to the positive traits of leadership, practical intelligence, wisdom, social intelligence, love of learning, spirituality, and the capacity to love and be loved. Students believed that strengths were largely acquired rather than innate and that these strengths developed through ongoing life experience as opposed to formal instruction. They cited an almost complete lack of contemporary role models exemplifying different strengths of character. Implications of these findings for the quantitative assessment of positive traits were discussed, as were implications for designing character education programs for adolescents. We suggest that peers can be an especially important force in encouraging the development and display of good character among youth.  相似文献

This paper analyzes the propaganda campaign orchestrated by the Russian authorities with the aim of promoting a version of the country’s history for political purposes. This version puts the accent on the exceptionality of Russian historical development, and is geared to endowing the figure of Vladimir Putin – seen as the person who has succeeded in carrying out a number of national projects that have been frequently abandoned throughout Russian history. The analysis presented here centres on two channels used in the campaign: school textbooks and the film industry.  相似文献

In this study we revisit the question of black representation on city councils and school boards using a novel substantive and methodological approach and longitudinal data for a sample of over 300 boards and councils. Conceptualizing black representation as a two-stage process, we fit Mullahy's hurdle Poisson models to explain whether and to what extent blacks achieve representation in local legislatures. We find that while the size of the black population and electoral arrangements matter more than ever, especially for overcoming the representational hurdle, the extent to which the black population is concentrated is also strongly associated with black council representation. Further, whereas black resources and opportunities to build "rainbow" coalitions with Latinos or liberal whites are marginally if at all related to black legislative representation, we find that legislative size is an underappreciated mechanism by which to increase representation, particularly in at-large systems, and is perhaps the best predictor of moving towards additional representation.  相似文献
