This research extends prior work that examines self‐esteem as an outcome of protective behaviors against crime victimization by focusing instead on the moderating influence of self‐esteem on the relationship between the fear of crime and the decision to protect oneself from victimization. The fear of crime is conceptualized as two separate components (fear of victimization and perceived risk) in accordance with prior work. Self‐esteem is conceptualized as three separate components (worth, efficacy, and authenticity), and measured with a recently designed instrument for capturing each aspect of self‐esteem separately. Data are collected through surveys of a population at high risk for victimization (undergraduate college students). Logistic regression analyses demonstrate that self‐esteem does play a role for deciding whether to engage in protective behaviors, and that the specific components of self‐esteem moderate defensive behavioral outcomes differently. Specifically, the self‐worth, self‐efficacy, and authenticity components of self‐esteem influence the decision to carry protection, but not the decision to take a self‐defense class. Implications for both the fear of crime and self‐esteem literatures are addressed. 相似文献

Women's growing numerical representation in the professions has not necessarily translated into women being truly integrated in these occupations. Questionnaire data are used to examine whether female physicians are socially integrated in the male‐dominated profession of medicine in terms of the support they receive from their medical colleagues compared to male physicians. The literature on tokenism and homophily suggests that women in male‐dominated professions receive less support than their male colleagues, whereas the social support literature predicts that women typically receive more emotional support than men but less informational and instrumental support. The results of this study shed light on the complex and multi‐layered ways in which gender is relevant to our understanding of the extent to which co‐workers provide empathy, information and assistance to one another. 相似文献

This paper considers the problem of selecting matched pairs of observations for the reduction of bias in statistical hypothesis testing. A Euclidean distance function is suggested for measuring the similarity between paired observations. The matching process is then formulated initially as an assignment problem. Alternative formulations of the problem that would reduce computational difficulty are considered. 相似文献

An important question with respect to government incentive contracts that has received little attention is: What alternatives to the current practice of making single-stage choices of incentive sharing rates can lead to situations in which these sharing rates can be chosen under reduced risk or cost uncertainty? This paper provides a decision-theoretic framework that illustrates a possibility of reducing risk, from the viewpoints of both the contracting parties, given some negotiated estimate of costs to be incurred. It is shown that such a possibility can arise in a situation in which it is technically feasible to separate or partition the contractual work into closely related tasks or units. Specifically, it is demonstrated that for a given cost estimate (target cost) and target profit, a set of optimal sharing rates (one for each unit) yields a higher risk-adjusted value of the contract than the single-stage sharing rate for the entire contract. 相似文献

We use data from the 1931, 1941, and 1951 censuses of India and the 1951 census of Pakistan to examine the demographic consequences of Partition in the Punjab in 1947. Had growth rates for the period 1931-41 for the Punjab as a whole continued to 1951, the population of the Punjab would have been 2.9 million larger than that recorded in 1951. Population losses from migration and mortality above age 20 were approximately 2.7 million greater between 1941 and 1951 than would have been predicted by loss rates between 1931 and 1941. We estimate a net Partition-related population movement out of the combined Punjab of about 400,000. We conclude from several lines of analysis that Partition-related population losses in the Punjab, either from deaths or unrecorded migration, were in the range 2.3-3.2 million. Partition was also marked by a dramatic religious homogenization at the district level. 相似文献

San Antonio, Texas, the seventh largest city in the United States, has experienced steady population growth, since the “boom”
of the 1960s. Projected water shortages due to this growth were realized as early as the 1970s by city leaders and south-central
Texas regional development decision makers. To reduce dependence on the already over-taxed, Edwards aquifer, a solution, the
Applewhite Dam and Reservoir Project, was developed with wide acceptance by federal, state, and city leaders who regarded
the project as a necessary measure for regional growth and development. However, opposition by taxpayer and environmental
groups led to referendums of 1991 and 1994 in which voters blocked construction of the dam and reservoir leaving the city
with limited options for water provision. This case study investigated the factors which led to a clear mismatch in communication
between decision makers—those who were aware of the actual and quantifiable risk to the region in terms of reduced water supplies—and
the general public, a population that did not have complete and/or adequate knowledge of their actual risk regarding future
water shortages, nor, of solutions being developed, such as the Applewhite project. The findings from this case study indicate
that when municipal leadership fails to adequately communicate risk regarding resource shortage to an affected public, as
well as, openly planned solutions, that voters are likely to underestimate future impacts of water shortages, heed last-minute
opposition, and reject long-standing, publicly proposed projects. The intent of this research is not to support either side
in the Applewhite controversy, but to shed perspective on the process of adequately and effectively communicating future water
needs to an at-risk population. Decision makers in cities across the United States who are faced with solving problems of
limited resources needed by a large populace may be informed by the results of this research. 相似文献
