The participants in this study were adult males (N = 111) who were accused of various sexual crimes against children 16 years of age or younger, and who were evaluated at a state forensic facility in a large Midwestern state. This study examined the relationship of Psychopathy Checklist-Revised (PCL-R) scores to type of child sexual offender (same sex extrafamilial, opposite sex extrafamilial, and incest offenders), the presence of violence during the most recent child sexual offense, and criminal versatility. Results indicated that those sexual offenders who employed physical violence against the children they abused were significantly more psychopathic than those who did not. No significant differences were found between types of child sexual offenders or with general criminal versatility. 相似文献

This research investigates three different indicators of at-risk socio-demographic conditions including dropping out of high
school, being idle, and being in highest-risk idleness among non-immigrant persons aged 19–24. Using data from the 2000 US
Census, our results detail the differentials in these characteristics for 30 different racial/ethnic groups that are further
broken down by gender. The findings indicate a wide range in the prevalence of these at-risk socio-demographic conditions.
Groups that tend to be the most at-risk in terms of these indicators include African Americans, Cambodians, Laotians, Native
Americans, other Hispanic whites, and white Mexicans. With the exception of the other Pacific Islander and Thai, young women
have lower high school dropout rates than do young men. However, young women are substantially more likely than young men
to be idle which we define as not being in school, the labor force, or the military. After defining highest-risk idleness
as never-married persons without children who are idle, however, the rates are slightly lower for young women than for young
men. 相似文献

Circular data arise in many contexts, a particularly rich source being animal orientation experiments. Often, in the analysis of such data, a fundamental question of scientific interest is whether the underlying distribution is reflectively symmetric about some specific axis. In this paper, the situation in which the axis of interest is known to be a median axis is considered and a simple, asymptotically distribution- free test for circular reflective symmetry against skew alternatives is developed. The results from a simulation study lead to a testing strategy incorporating the new test and the circular analogue of the modified runs test of Modarres & Gastwirth (1996). The application of the testing strategy is illustrated using circular data arising from two animal orientation experiments. 相似文献

This paper explores the discourses of ‘old-comer’ Korean communities (zainichi) in Japan in relation to the recent advent of notions of coexistence (kyōsei) and multiculturalism (tabunka). I adopt an analytical framework that has been used to critically examine Australian multiculturalism, recognising that although the Australian context is different, this analytical framework is useful for the examination in hand. I argue that although the discursive recognition of Japan as multicultural is an important step away from ubiquitous notions of monoculturality, this relatively new direction needs to be balanced with critical interrogation of how it is being represented. The results of this research clarify the positions adopted by the Korean diaspora in Japan and offer a possible alternative perspective on the way forward. 相似文献

The author addresses the problem of testing circular data for reflective symmetry about an unknown central direction and proposes a simple omnibus test based on the sample second sine moment about an estimation of this direction. Under quite general conditions, for an underlying distribution which is reflectively symmetric, the large‐sample asymptotic distribution of the test statistic is standard normal. Randomization and bootstrap variants of the test are also introduced, and the operating characteristics of different versions of the test are investigated in a Monte Carlo study. The large‐sample and bootstrap versions of the test are applied in the analysis of two illustrative examples drawn from the circular statistics literature. 相似文献

North American problems in coming to terms with the management of the semi-arid Plains environment are well known. Less documented are those of Argentina's equivalent on the fringe of the Humid Pampas. Argentine agricultural aid and research has been focussed on the Humid Pampas, and little understanding of the special problems of the dry zone is apparent. Issues of production and conservation are in urgent need of attention. In addition to the limits posed by the natural environment, a number of human factors affect the ability of ranchers to produce from the dry lands. In a field study of the Caldenal, some indications are that the factors are different from other environments in Latin America. Large properties are not less productive per hectare than small, and standard technology does not guarantee good results from ranching. Tenant farming is not a problem, but there is an impoverished group, those ranchers without other means of earning a livelihood. A recommendation is for encouragement to be given to larger ranch units, and for more research into relevant technology, which is likely to include conservationist measures, whose introduction to the ranches should be financially supported. 相似文献

This paper describes mental health risks to the birth-to-three foster care population. The paper describes risks of a relational and contextual nature. Relational risk factors, which have been previously identified by foster care researchers and clinicians, include the following: 1. Poor attachment signaling by foster infants and toddlers; 2. Discomfort with infant and toddler dependency by some foster parents; and 3. Regulatory problems of foster infants and toddlers. Contextual risk factors include the following: 1. Lack of coordinated and coherent efforts to help foster infants and toddlers and; 2. Lack of support for the parent–child relationship during placement. A case example and discussion is offered to illustrate these risks. 相似文献

The profession's present role in day care is assessed through a review of the social work literature. This analysis suggests that the profession is not systematically involved enough in child care systems on a local or national basis. The author discusses why this is so, and suggests professional points of access for social workers interested in providing social services in different types of child care. In addition, it is recommended that more policy and programmatic emphases be put on providing social services to family day care homes, the care of children by their relatives, and for centers that serve ethnic minorities and disadvantaged families.I wish to thank Beatrice Saunders and Eleanor Brilliant for their help in writing this article. 相似文献

The research and development project selection process is one of the most difficult and important problems faced by management. It is typically complicated by indivisibility of projects and multiple and conflicting objectives, in addition to limitations on funding, facilities, and qualified researchers. In this paper a case example involving a high technology electrical equipment manufacturer is developed to illustrate this problem using zero—one goal programming to accommodate indivisibility of projects in addition to multiple and conflicting goals. The model presented is an attempt to provide managers with a robust tool for allocating scarce resources among research and development projects. 相似文献
