Gender and racial/ethnic differences in addiction severity, HIV risk, and quality of life among adults in opioid detoxification: results from the National Drug Abuse Treatment Clinical Trials Network.

PURPOSE: Detoxification often serves as an initial contact for treatment and represents an opportunity for engaging patients in aftercare to prevent relapse. However, there is limited information concerning clinical profiles of individuals seeking detoxification, and the opportunity to engage patients in detoxification for aftercare often is missed. This study examined clinical profiles of a geographically diverse sample of opioid-dependent adults in detoxification to discern the treatment needs of a growing number of women and whites with opioid addiction and to inform interventions aimed at improving use of aftercare or rehabilitation. METHODS: The sample included 343 opioid-dependent patients enrolled in two national multi-site studies of the National Drug Abuse Treatment Clinical Trials Network (CTN001-002). Patients were recruited from 12 addiction treatment programs across the nation. Gender and racial/ethnic differences in addiction severity, human immunodeficiency virus (HIV) risk, and quality of life were examined. RESULTS: Women and whites were more likely than men and African Americans to have greater psychiatric and family/social relationship problems and report poorer health-related quality of life and functioning. Whites and Hispanics exhibited higher levels of total HIV risk scores and risky injection drug use scores than African Americans, and Hispanics showed a higher level of unprotected sexual behaviors than whites. African Americans were more likely than whites to use heroin and cocaine and to have more severe alcohol and employment problems. CONCLUSIONS: Women and whites show more psychopathology than men and African Americans. These results highlight the need to monitor an increased trend of opioid addiction among women and whites and to develop effective combined psychosocial and pharmacologic treatments to meet the diverse needs of the expanding opioid-abusing population. Elevated levels of HIV risk behaviors among Hispanics and whites also warrant more research to delineate mechanisms and to reduce their risky behaviors.

Reflexôes sobre discriminacâo étnico-racial e práctica docente em matemática: uma experiência na eja

El presente artículo tiene como objetivo presentar los resultados de la investigación realizada con alumnos jóvenes y adultos en una escuela pública en la ciudad de Uberlandia/MG (Brasil), tratando de reflexionar y aprender a percibir la presencia de conocimientos africanos en matemáticas por manifestaciones de tradiciones afro-brasileñas, además de identificar que los estudiantes contemplando la cuestión de la raza, apodos y la imagen que tienen de las matemáticas y de las tradiciones afro-brasileñas, con miras a desarrollar una educación enraizada en los fundamentos de nociones, que busca reforzar la producción de conocimientos matemáticos a otros grupos sociales para una matemática crítica e incluyente. La encuesta también trató de contribuir al desarrollo de acciones educativas basadas en la ley brasileña 10.639/03. La enseñanza de las matemáticas, teniendo debidamente en cuenta los cultivos afro brasileños también tienen mucho que contribuir a la comprensión del mundo como una posibilidad para desarrollar valores y ampliar conceptos.

Qualitative methods in the study of children's racial attitudes and identities

This article examines the role that qualitative methods can play in the study of children's racial attitudes and behaviour. It does this by discussing a number of examples taken from a qualitative, ethnographic study of five- and six-year-old children in an English multi-ethnic, inner-city primary school. The examples are used to highlight the limitations of research that relies solely on quantitative methods and the potential that qualitative methods have for addressing these limitations. Within this context the article contrasts the strengths and weaknesses of qualitative and quantitative methods in the study of children's racial attitudes and identities. The article concludes by arguing that a much more integrated multi-method approach is needed in this area and sets out some of the most effective ways this could be achieved.

Cultural politics and the racial cartographics of human origins

Discussions about human origins, both scientific and pre-scientific, have frequently been freighted with the cultural politics of race relations and questions about human equality. In one way or another, maps have played a critical role in these enterprises by presenting in visual form narratives of human genesis and patterns of human ancestral lineages. In this paper I discuss how a sequence of cartographic representations of human beginnings have transacted racial power from the middle ages to the present day.
