The purpose of this article is to examine the self-reported sexual attitudes and behaviors of adolescents living in the Midwest. A survey was administered to 463 African American youths ages 11-19. The results indicate that intent to have sexual intercourse, reported likelihood toward having sexual intercourse, and whether participants felt that they would have sex in the next 3 months were predictors of whether they had sexual intercourse at the 3-month follow-up. The results also revealed that the opinions of referent others did not predict sexual intercourse at 3 months. Negative attitudes toward condoms did predict condom use at 3 months and the opinions of referent others also predicted condom use at 3 months. Limitations as well as future research are also discussed. 相似文献

The Ohio Attorney General's Sexual Assault Kit (SAK) Testing Initiative has resulted in nearly 14,000 kits being processed since the initiation of the project in 2012. A logistic regression model was fit to the data from 2500 SAKs in order to determine the probability of obtaining at least one Combined DNA Index System (CODIS) eligible DNA profile based on a number of predictor variables. The probability of obtaining at least one CODIS eligible DNA profile from an SAK varied as a function of (i) days to kit collection following a sexual assault; (ii) years to kit submission to the laboratory for testing following kit collection; (iii) the age of the victim; and (iv) the occurrence of victim‐reported consensual sex around the time of the assault and/or kit collection. These findings demonstrate the utility of the statistical modeling of data obtained from the “forklift” testing approach of sexual assault kits. 相似文献

The Programme de recherche en démographie historique (Historical Demography Research Programme) (PRDH), founded in 1966 and based at the Département de Démographie of the Université de Montréal, has since its inception featured a central project, a family reconstitution database of Quebec’s Catholic population from 1621 to 1799 named the Registre de la population du Québec ancien (Population Register of Historic Quebec) (RPQA). This article, which marks the fiftieth anniversary of the project, explores the development of the RPQA over the five decades in the context of similar international databases, explains the current state of the database as well as our record linkage methodology, describes an important collaboration now underway to build a larger Quebec historical data infrastructure, outlines new and renewed international collaborations, and summarizes research conducted using these data as well as future research possibilities. The particular geographic context, historical development and manageable colonial population size of Quebec favoured family reconstitution of the whole colony from the beginning of the project. Today, the RPQA comprises 438,193 individual biographies and 74,000 family files encompassing up to nine generations. To reconstitute families, we must identify and incorporate into the database all demographic events, including those whose existence can only be inferred through other sources. Future efforts to link nineteenth-century parish acts will need to deal with large case counts, mixed Catholic–Protestant marriages, and increased geographic and social mobility. The integration of complementary data will provide information on household co-residence, occupations, help track the destinies of mixed-religion persons and persons outside nuclear families and provide additional points of observation. 相似文献
