This study analyzed 390 (303 girls and 87 boys) cases of child sexual abuse to understand sex differences in child sexual victimization. Analyses focused on three domains that have received considerable empirical attention: victims' relationships with the offender, type and extent of abuse, and disclosure. Findings largely replicated previous efforts that reported sex differences in terms of victims' relationships with offenders. Although results also replicated previous findings about sex differences in disclosure patterns, these sex differences were minor in comparison with similarities in the way most instances of abuse were eventually identified. In terms of type and extent of abuse, results were the opposite of previous findings: girls, not boys, were the victims of more physical injury, violent threats, and use of force; and girls, not boys, were more likely to have physically resisted abuse. Divergences in findings were interpreted in terms of memory biases and social forces operating differently on the sexes.  相似文献

This paper sets up a model of household dissolution in which one party decides to leave a household that contains children. We study the effects of divorce law on this decision and, in particular, the role of legal provisions governing the post-dissolution care of the household’s children. In particular, we show that there is an inevitable tension between achieving efficiency in marriage and at the same time achieving efficiency in divorce.  相似文献

State spaceports are an interesting example of intergovernmentalrelations because activities conducted at such facilities spanthe state, federal, and international realms. Five states—Alaska,California, Florida, New Mexico, and Virginia—are themost visible participants in the process. In this study, thesupporting rationales for such endeavors are discussed withinthe context of the broader contours of intergovernmental relations.The field is a product of the post-Cold War period during whichopportunities for state space activities arose due to changesin the national security environment. Three distinct but interrelatedexplanations are suggested for why the field has developed slowly,although during the past two years, progress in achieving goalshas begun to occur.  相似文献

Existing research highlights that families face geographic, social, and psychological constraints that may limit the extent to which competition can take hold in school choice programs. In this paper, we address the implications of such findings by creating a network of student flows from 11 cohorts of eighth‐grade students in the Chicago Public Schools (CPS). We applied a custom algorithm to group together schools with similar sending and receiving patterns, and calculated the difference in mean achievement between a student's attended and assigned high schools. For all identified school groupings, we found that the students were on average moving to higher achieving schools. We also found that the movement toward higher achieving schools of the top achievement quartile of students was over twice as large as that of the bottom quartile, but that the flows of both the highest and lowest achieving student quartiles were toward higher achieving destinations. Our results suggest that student movements in CPS between the years of 2001 to 2005 were consistent with creating market pressure for improvement as well as increasing segregation by achievement. However, further research into how schools responded to those movements is required to make inferences about the level or consequences of competition generated by choice‐related reforms during that time.  相似文献

The ingestion of corrosive substances may produce severe burns to the upper aerodigestive tract and stomach, particularly if the pH is greater than 12 or less than two. There is a biphasic age grouping with adult cases most often involving self‐harm and pediatric cases accidental ingestion. Three cases are reported to demonstrate characteristic features following the ingestion of potassium hydroxide, glacial acetic acid and Lysol®, respectively. All deaths were due to the effects of caustic burns to the upper aerodigestive tract, esophagus and stomach with perforation and/or hemorrhage. The extent of injuries in these cases depends on the nature, amount, and concentration of the agent and on the exposure time. A point to note at autopsy is that tissue damage may also occur from postmortem exposure. Typical injuries involve perioral, limb, and trunk burns, with extensive aerodigestive liquefactive/coagulative necrosis causing hemorrhage and perforation.  相似文献

Although well placed to render assistance to refugees, indigenous NGOs usually play only a marginal role, compared with the Northern NGOs which dominate most humanitarian aid programmes. The unbalanced power relations between Northern agencies and donors and Southern NGOs in the delivery of refugee assistance are reviewed. Using data from the assistance programmes for Mozambican refugees in Malawi and Zimbabwe, the strategies and conditions by which some indigenous NGOs successfully challenged this prevailing situation are examined. Factors considered to be significant are institution building; diversifying the donor-base; project design and development; and the skills and expertise of field directors. The broader applicability of these experiences is considered.  相似文献
