Sex Determination by Discriminant Function Analysis of Lumbar Vertebrae

Sex determination is critical for developing the biological profile of unidentified skeletal remains. When more commonly used elements (os coxa, cranium) for sexing are not available, methods utilizing other skeletal elements are needed. This study aims to assess the degree of sexual dimorphism of the lumbar vertebrae and develop discriminant functions for sex determination from them, using a sample of South African blacks from the Raymond A. Dart Collection (47 males, 51 females). Eleven variables at each lumbar level were subjected to univariate and multivariate discriminant function analyses. Univariate equations produced classification rates ranging from 57.7% to 83.5%, with the highest accuracies associated with dimensions of the vertebral body. Multivariate stepwise analysis generated classification rates ranging from 75.9% to 88.7%. These results are comparable to other methods for sexing the skeleton and indicate that measures of the lumbar vertebrae can be used as an effective tool for sex determination.

Strain,Negative Emotions,and Deviant Coping Among African Americans: A Test of General Strain Theory

Although previous research on Agnew's (1992) general strain theory (GST) tends to yield significant effects of strain on negative emotions as well as deviance and crime, results tend to be mixed with regard to (1) the effects of negative emotions on deviance and crime and (2) conditioning factors that Agnew suggests affect the selection of coping strategies. To address these issues, we test hypotheses, derived from GST, about the relationships among strain, negative emotions, and deviant coping by analyzing data from a nationally representative sample of African American adults. Ordinary least squares regression results generally support our hypotheses. First, fully mediating the effects of strain on deviant coping, negative emotions have consistently significant effects on deviance, regardless of whether we use composite or separate measures of inner- and outer-directed emotions and deviance. Interestingly, as hypothesized, the same-directed effects of negative emotions on deviant coping are larger than the opposite-directed ones. Second, while self-esteem and self-efficacy as conditioning factors generally fail to receive empirical support, religiosity is found to significantly buffer the effects of negative emotions on deviance. Implications of our findings for further development of GST are discussed.     

The W***D C*P of 2*1*: FIFA's intellectual property rights in South Africa

Legal context: This article focuses on the relationship between trade markrights and other forms of statutory protection. Key points: FIFA is the proprietor of a number of trade mark registrationsin South Africa. The strength of these registrations is discussedand the view taken that a number are open to attack, in termsof both distinctiveness and user requirements. It is then shownthat, if statutory protection is given for the same words andphrases, the weaknesses of the trade mark registrations willbe avoided. Practical significance: The article serves as an illustration of the manner in whichinternational sporting bodies attempt to extend their IP protectionbeyond the bounds of existing legislation.     

'Dat Var Negressen Walaida Snow'

This essay is about the jazz musician and black variety stage artist Valaida Snow and the years she spent caught in Nazi occcupied Denmark. Despite rumors that she was held in a concentration camp, this essay argues that she may in fact have been shielded from the occupiers by the Danes. This essay argues that a masculinist bias in popular cultural/jazz studies obscures the histories of black women expressive artists and limits theoretical possibilities in the study of performance. It argues that the study of black women performers demands the development of more supple analytical models that attend to the heterogeneity of black expressive forms.

Coparent Support and Conflict in African American Single Mother-Headed Families: Associations With Maternal and Child Psychosocial Functioning

This longitudinal investigation examined main and interactive effects of coparent support and conflict on mother and child adjustment in 248 low-income, African American, single mother-headed families. The findings indicated that coparent conflict was a more robust predictor of mother and child maladjustment both cross-sectionally and longitudinally than was coparent support. Moreover, findings revealed that coparent conflict and support interacted to predict one parenting behavior, monitoring, both cross-sectionally and longitudinally. Coparent relationships characterized by high levels of support and low levels of conflict were associated with the highest levels of parental monitoring behavior, whereas coparent relationships characterized by low levels of support and high levels of conflict were associated with the lowest levels of monitoring. The findings highlight the importance of examining both positive and negative aspects of coparent relationships in this at-risk, but understudied, group.     

Coparenting Conflict and Parenting Behavior in Economically Disadvantaged Single Parent African American Families: The Role of Maternal Psychological Distress

Substantial research has focused on the negative associations between coparenting conflict, parental psychological functioning, and parenting behavior in European American, middle-income, families. However, less attention has been given to ethnic minority families and to families that are nontraditionally structured. In an effort to address this gap, the current longitudinal study examines the relation between conflict with the mother-identified primary co-caregiver and parenting practices in single parent, economically disadvantaged African American families. Participants included 234 mother–child dyads. It was hypothesized that conflict would relate to less utilization of positive parenting practices and that this association would be mediated, at least in part, by maternal psychological distress. Hypotheses were examined using structural equation modeling (Lisrel 8.3): Conflict with a co-caregiver was significantly related to parenting both directly and indirectly through maternal psychological distress. Implications of the findings are discussed.

Articulating language oppression: colonialism,coloniality and the erasure of Tibet’s minority languages

ABSTRACT

Roche’s article discusses ‘language oppression’ as a form of domination that is coherent with other forms of oppression along the lines of ‘race’, nation, colour and ethnicity. Scholars have defined language oppression as the ‘enforcement of language loss by physical, mental, social and spiritual coercion’. It is part of an evolving suite of concepts from linguistics, sociolinguistics and linguistic anthropology that examines issues of language discrimination, or ‘linguicism’. Roche explores one aspect of linguicism—language erasure—and how it relates to language oppression, focusing on Tibetans in the People’s Republic of China (PRC). He examines how language oppression is produced through practices of erasure: the ways in which certain populations and their languages are systematically rendered discursively invisible. He argues that the erasure of certain languages in the Tibetan context is systematically reproduced by two otherwise opposed political projects: the colonial project of the PRC state; and the international Tibet movement that seeks to resist it. He refers to the contingent cooperation between these two opposed projects as ‘articulated oppression’. In concluding the article he examines how the disarticulation of this oppression is a necessary condition for the emancipation of Tibet’s minority languages, and discusses the broader significance of this study for understanding language oppression, and its relation to other forms of oppression.
