Recently, Hefner and Ousley (2014) introduced the optimized summed scored attributes (OSSA) method that maximizes between‐group differences in U.S. black and white populations by dichotomizing six cranial morphoscopic trait scores. This study tests OSSA using an independent skeletal sample (Hamann‐Todd, n = 208) and positively identified forensic cases (Mercyhurst University, n = 28, and New York City Office of Chief Medical Examiner, n = 38). An evaluation of trait frequencies suggests shifting the heuristically selected sectioning point separating U.S. black and white populations from ≤ 3 to ≤ 4. We found a total correct classification of 73.0% (B = 50.9%, W = 89.2%) using the originally suggested sectioning point of ≤3, while the total correct classification increases to 79.2% (B = 80.2%, W = 78.5%) with a modified sectioning point of ≤4. With the increased total correct classification and reduced classification bias between ancestry groups, we suggest the modified sectioning point of ≤4 be used when assessing ancestry in forensic unknowns. 相似文献

This study tested associations between adolescent perceptions of interparental conflict, adolescent attachment security with parents, and adolescent marital expectations and romantic experiences. Participants were 96 early adolescent females from 2 parent families. Insecurity was examined as a mediator of the association between negative perceptions of parental conflict and romantic outcomes. Results supported the mediation model in which adolescents' negative perceptions of parental conflict was associated with insecure attachment with parents, which was in turn associated with negative marital expectations and romantic experiences. Implications for understanding how parent-adolescent and interparental variables influence adolescent marital expectations and romantic experiences are discussed.

ABSTRACT This article examines the citizenship dimension of transnational inequalities. It is clear that some citizenships offer great advantages while others are liabilities for the individual, and the aim of this present article is to develop a conceptualisation of citizenship and inequality, in order to be able to assess and compare them. For this purpose, elements of Pierre Bourdieu's sociology are utilized. The argument is that citizenship can be thought of as a form of capital in this Bourdieusian sense – that is, as a resource with which individuals are more or less endowed, and which impacts on people's transnational social positions, their capacities for action, their strategies and perceptions. The main contribution is to develop this idea, which is referred to as “citizenship capital”. Its usefulness is demonstrated by considering its interaction with economic capital for shaping positions in transnational social space. 相似文献

The instrumentalist literature suggests that women can help achieve household food security if they have access to productive resources but do not become overburdened as a result. This paper seeks to assess the relevance of this literature by exploring the gendered cycles of food insecurity in the context of women’s informal labour in northern Mozambique. It considers the relation between women and food security as embedded in the broader socio-economic setting, and finds that the interaction of different forms of deprivation, such as lack of secure employment and conflicting labour demands, generates food insecurity. 相似文献

Varices are the main clinical manifestation of portal hypertension, and their bleeding is the predominant cause of mortality from this condition. Periumbilical varices are known as “caput medusae.” Reports of their bleeding are rare, with only three fatal cases described in the literature. The antemortem diagnosis is relatively simple, while the postmortem diagnosis is more complex. This paper is the first report of fatal hemorrhage from a caput medusae for which the diagnosis was made postmortem, thanks to a complete diagnostic process including scene and circumstances, medical history, and autopsy with detailed histology. The circumstantial analysis showed the presence of a large amount of blood at the scene, blood which originated from a small abdominal wound; an analysis of the subject's clinical data reported that he was affected by portal hypertension. The autopsy revealed some dilated and convoluted veins in the subcutaneous tissue of the umbilical region; a fistula between these veins and the abdominal wound was detected. The histological study confirmed the presence of periumbilical varices, one of them ruptured and connected with the overlying skin. The cause of death was attributed to a massive hemorrhage generated by a periumbilical varix in a patient affected by portal hypertension. 相似文献

ABSTRACTSince a substantial proportion of sexual offenders are not apprehended, researchers have introduced methods to test the propensity to sexually offend among the general public. Proclivity measures assess self-reported sexual interest in lone and multiple perpetrator sexual offending or rape (MPR), and can examine students and community members who indicate a proclivity to sexually offend. This study examines the role of pornography use and rape supportive cognitions to influence proclivity. Anonymous online data was collected from 295 male university students to assess the role of rape supportive cognitions and pornography use in predicting lone and MPR proclivity. Only rape supportive cognitions predicted scores on lone and MPR proclivity measures. 相似文献
