A number of researchers have recently challenged the long-held notion among criminologists that rape, along with most other
violent crimes, is an intraracial crime. Based on analysis of survey data they concluded that black rapists “prefer” or “seek
out” white victims and that the likelihood of a black offender selecting a white victim has been increasing during recent
years. Data presented here (1977–88 National Crime Surveys) refute the notion that black rapists “prefer” white victims. Moreover
these same data fail to support the contention that rapes involving black offenders and white victims have been increasing.
According to National Crime Survey estimates, the proportion of black offenders that victimize whites has been declining.
An earlier version of this paper was presented at the annual meetings of the American Society of Criminology, November 1991. 相似文献

The theory of family paradigms provides an integrative framework for under-standing and systematizing the diverse ways that families organize and make sense of family life. Using formal methods of analysis based on logical and geometrical arguments, the priecise implications of models of family types can be investigated and compared. The paradigmatic framework can thus be refined and extended to form a more rigorous theoretical grounding for family typologies is explored and a miltidimensional model is derived the geometry of which is equivalent to, but more succinctly captures, the underlying structure of uariation in family para-digms. In Part II, the resulting model is interpredtd and explored in terms of implications for family theory, theory construction, and family therapy. Clarifying the basic dimensions of the paradigmatic framework also permits more precise exploration of interrelationships among related models of family types, which can be understood as reduced models derivable from the complete geometry of the paradigmatic framework. 相似文献

Previous investigations have shown that a social choice function which is partially implementable must be characterized by pervasive veto power. This paper investigates how much additional latitude in the design of social choice functions, and how much relief from this vetoers result, can be achieved by examining multi-valued social choice rules and relaxing the requirement of partial implementability to a requirement that we call weak partial implementability. We find that the power structures which characterize partially implementable social choice functions, including the veto properties, also characterize weakly partially implementable social choice rules. The conclusion is that invoking multi-valuedness and implementation of appealing social choice rules in strong Nash equilibria. Our results apparently exhaust the possibilities for implementation in strong Nash equilibrium. If any implementation possibility results are to be achieved, they can apparently come only by weakening the equilibrium requirement. 相似文献

A theoretical model of human systems is presented based on the basic paradigms upon which families, groups, and social systems can be organized. Four fundamentally distinct paradigms are described and the interrelationships among them explored, with special consideration given to the social evolution of systems organized on these paradigms. Implications for the study of alternative lifestyles and utopian societies are discussed.Portions of this paper are based on a presentation at the Fifth Annual Conference on Utopian Studies, Pennsylvania State University, 11 October 1980. The author wishes to thank Rich Erlich, Barry Singer, and Kersti Yllo for valuable comments on earlier versions. Inquiries to the author: 22 Bulette Road, Acton, Massachusetts 01720. 相似文献

Characteristics of the population and economic measures that constitute traditional social indicators are compared with more recent “quality of life” measures to demonstrate that social indicators are always value statements at the policy level. The possibility of alternative perspectives is illustrated. It is suggested that an awareness of the assumptions implicit in any given indicator is as important as the data they provide. 相似文献

Revolutionary products often come from upstart players or companies outside the industry, while mainstream operators follow a risk-averse path of concentrating on their current business. This article urges companies to channel resources into looking at the periphery for ideas that could be profit-drivers of the future. It suggests three strategies for finding new products: frame the landscape; develop game-changing hypotheses; and use targeted hunting. It concludes by saying that these approaches will encourage managers to combine broad searching and thinking with focused evaluation and execution. 相似文献

The violent attack on the staff of Charlie Hebdo and an earlier plot to kill cartoonists from the Danish newspaper Jyllands-Posten raise the issue of censorship of satirical religious cartoons to avoid potential retaliatory violence from those offended by the cartoons. With third-person effect (TPE) as the theoretical underpinning, this study examined the relationship among TPE, religiosity, and support for censorship of religious satirical cartoons. Data were collected in May 2015. A national sample of participants (N=374) was acquired through Amazon’s Mechanical Turk. The results show that individuals with a higher degree of religiosity are more likely to support censorship of satirical religious cartoons, and though TPE is not positively correlated to support for censorship, respondents’ perception of the effect of the cartoons on themselves may indicate an increased propensity for supporting censorship. 相似文献

This study used a factorial experimental design and a new modeling methodology to investigate the impact of a number of labor scheduling flexibility alternatives and labor requirements characteristics on labor utilization within a tour scheduling environment. Break-placement flexibility and shift-length flexibility were found to be extremely effective in improving labor utilization for all labor requirement distributions used. Flexibility with respect to the number of days included in a tour schedule resulted in substantial improvement in labor utilization for all labor requirements distributions exhibiting daily and/or weekly variation. Surprisingly, virtually no improvement in labor utilization was achieved for any labor requirement distribution by the removal of requirements for consecutive days off. In addition, almost no improvement was found by allowing the shift start time to vary across the working days included in tours. High labor requirement amplitude was found to have a strong adverse effect on labor utilization while longer operational days were associated with improved labor utilization for all labor requirement distributions. We discuss the implications of these results for service operations management and provide suggestions for future research. 相似文献
