The aim of this study was to investigate the relationship between developmental factors and deviant sexual preferences in child molesters. In total, 146 adult males having committed a sexual offence against a child were included in the study. Three types of factors were investigated: negative experiences during childhood, behavior problems during adolescence, and sexual criminal activity in adulthood. Negative experiences and behavior problems were assessed through a semistructured interview. The sexual criminal activity was determined using police records. Sexual preferences towards children were assessed using phallometric assessment. Hierarchical regression analyses suggested the presence of two developmental pathways. The psychosocial deficits pathway is related to a sexual interest for nonviolent sexual stimuli involving children. The sexualization pathway is associated with a sexual interest for violent sexual stimuli involving children. These two pathways are discussed in light of previous empirical findings related to the development of deviant sexual preferences in child molesters.  相似文献

During the last few years, the number of privately ordered paternity investigations has increased considerably. Probably due to financial reasons in more and more cases only the putative father and the child are investigated. Additionally, very often only one method, such as STR analysis, is employed. This raises the question whether such a reduced analysis leads to reliable and clear results when investigating cases with related putative fathers. We investigated 165 individuals from 27 families using the AmpFlSTRIdentifiler multiplex PCR and calculated the paternity probabilities of the children to their biological fathers, uncles, grand fathers and other relatives. In more than 30% less than three exclusions between child and relative were detected. In five cases no exclusions were found between child and uncle, always leading to paternity probabilities >99.9%. These results show that the calculation of high probabilities (>99.9%) does not necessarily lead to the accurate conclusion of fatherhood. In many of our cases misleadingly the brother of the real father or another close relative would have been declared to be the biological father.  相似文献

In this paper we estimate the macroeconomic consequences of terrorism using panel data for 147 countries for the period 1968–2002. The results reveal that the potential gains to a country from reducing terrorism are quite large, although the specific estimates depend on a country's population, base level of output, and investment. We present estimates of the impact of terrorism on GDP, GDP growth, investment, consumer spending, and tourism. These estimates of the marginal impact of terrorism provide a threshold against which a country's expenditures on anti-terrorism can be weighed.  相似文献

Cultural differences have been found in body image perceptions among Black and White adolescents, however little is known about the factors associated with perceptions of an ideal body size (IBS). This study examined differences in correlates of IBS among 265 Black (116 girls and 62 boys) and White (63 girls and 24 boys) adolescents. IBS for White girls and boys was related to perceptions of how their parents wanted them to look, while IBS for Black girls was related to perception of how peers look and would like to look. IBS for Black boys was significantly related to perceptions of their current size, how peers would like to look, how parents think they look, and depressive symptoms. Findings suggest cultural differences in the factors related to body image perceptions and have implications for educational programs promoting healthy body image development among Black and White adolescents.Assistant Professor, Department of Preventive Medicine and Public Health, University of Kansas Medical Center.

Recent challenges to fingerprint evidence have brought forward the need for peer-reviewed scientific publications to support the evidential value assessment of fingerprint. This paper proposes some research directions to gather statistical knowledge of the within-source and between-sources variability of configurations of three minutiae on fingermarks and fingerprints. This paper proposes the use of the likelihood ratio (LR) approach to assess the value of fingerprint evidence. The model explores the statistical contribution of configurations of three minutiae using Tippett plots and related measures to assess the quality of the system. Features vectors used for statistical analysis have been obtained following a preprocessing step based on Gabor filtering and image processing to extract minutia position, type, and direction. Spatial relationships have been coded using Delaunay triangulation. The metric, used to assess similarity between two feature vectors is based on an Euclidean distance measure. The within-source variability has been estimated using a sample of 216 fingerprints from four fingers (two donors). Between-sources variability takes advantage of a database of 818 ulnar loops from randomly selected males. The results show that the data-driven approach adopted here is robust. The magnitude of LRs obtained under the prosecution and defense propositions stresses upon the major evidential contribution that small portions of fingermark, containing three minutiae, can provide regardless of its position on the general pattern.  相似文献

Prevalence and correlates of adult physical assault and rape in six Native American tribes are presented (N = 1,368). Among women, 45% reported being physically assaulted and 14% were raped since age 18 years. For men, figures were 36% and 2%, respectively. Demographic characteristics, adverse childhood experiences, adulthood alcohol dependence, and cultural and regional variables were assessed. Using logistic regression, predictors of physical assault among women were marital status, an alcoholic parent, childhood maltreatment, and lifetime alcohol dependence. Predictors of sexual assault among women were marital status, childhood maltreatment, and lifetime alcohol dependence. Among men, only childhood maltreatment and lifetime alcohol dependence predicted being physically assaulted. Tribal differences existed in rates of physical assault (both sexes) and rape (women only). The results underscore the problem of violence victimization among Native Americans and point to certain environmental features that increase risk of adulthood physical and sexual assault. Implications for tribe-specific interventions are discussed.  相似文献
