SexEd.com: Values and norms in web‐based sexuality education

The sexual values and norms transmitted to adolescents through school‐based sexuality education programs have been noted and critiqued by an interdisciplinary pool of researchers. With the increasing availability of the Internet to many American adolescents, the opportunities it provides for discreet and independent exploration, and the virtual lack of regulation of information provided by web sites, the Internet is emerging as a unique and critical site of sexuality education. This work analyzes the values and norms transmitted to adolescents via 52 sexuality education web sites, drawing parallels to its school‐based counterpart and interrogating the reliance of all forms of sexuality education on a problem‐focused, gendered, and narrowly‐bounded discourse of adolescent sexuality.

Estimation in capture–recapture models when covariates are subject to measurement errors and missing data

For capture–recapture models when covariates are subject to measurement errors and missing data, a set of estimating equations is constructed to estimate population size and relevant parameters. These estimating equations can be solved by an algorithm similar to the EM algorithm. The proposed method is also applicable to the situation when covariates with no measurement errors have missing data. Simulation studies are used to assess the performance of the proposed estimator. The estimator is also applied to a capture–recapture experiment on the bird species Prinia flaviventris in Hong Kong.

Ridge regression: A multivariate analysis of criminal activity

The objective of the paper is to apply the statistical procedure of ridge regression to a multivariate model of criminal activity. The explanatory variables are of an economic, apprehension, and seasonal nature. The Time Shared Reactive On Line Laboratory (TROLL) computer package was used in estimating all regression coefficients and other pertinent statistics. The economic variables, which included per capita personal income, hours worked, and plant closing dummy variable, were found to be statistically related to criminal activity. In addition, police expenditures as well as the three seasonal dummy variables were statistically associated with the dependent variable. A comparison is made between the results obtained from the ordinary least squares procedure and the ridge regression approach.     

Child custody issues and co‐occurrence of intimate partner violence and child maltreatment: controversies and points of agreement amongst practitioners

The situation of families undergoing separation in a context of co‐occurrence of intimate partner violence (IPV) and child maltreatment raises certain issues related to child custody. The results presented in this paper were collected and analysed within the framework of a qualitative study aiming to identify the principal points of agreement and the main controversies amongst practitioners in several different types of organizations. Focus groups were held with a total of 43 practitioners from six different settings concerned with child custody in cases of co‐occurrence of IPV and child maltreatment. Although they agreed on the importance of ensuring the safety of victims of violence, their views diverged on three points: (1) the importance of preserving the father–child relationship; (2) collaboration between voluntary organizations and semi‐voluntary or legal agencies; and (3) consideration of cultural differences.     

Motivators for Resolving or Seeking Help for Gambling Problems: A Review of the Empirical Literature

This literature review summarizes recent empirical research on the reasons disordered gamblers try, through treatment or otherwise, to resolve or reduce their gambling problems. Relevant databases and bibliographies were searched for English-language studies, published since 1998, that asked gamblers themselves about motivators for action. Found were ten studies addressing reasons for trying to resolve or reduce gambling problems, five addressing reasons for seeking help and four addressing reasons for requesting self-exclusion from casinos. Help-seeking occurred largely in response to gambling-related harms (especially financial problems, relationship issues and negative emotions) that had already happened or that were imminent. Resolution was often motivated by the same kinds of harms but evaluation/decision-making and changes in lifestyle or environment played a more prominent role. Self-exclusion was motivated by harms, evaluation/decision-making and a wish to regain control. Awareness and educational materials could incorporate messages that might encourage heavy gamblers to make changes before harms became too great. Intervention development could also benefit from more research on the motivators leading to successful (vs. failed) resolution, as well as on the ways in which disordered gamblers are able to overcome specific barriers to seeking help or reaching resolution.     

PUBLIC SCHOOL SEGREGATION AND JUVENILE VIOLENT CRIME ARRESTS IN METROPOLITAN AREAS

Previous research has established an association between residential segregation and violent crime in urban America. Our study examines whether school‐based segregation is predictive of arrests of juveniles for violent crimes in U.S. metro areas. Using Census, Uniform Crime Report, and Common Core data for 204 metro areas, a measure of school‐based racial segregation, Theil's entropy index, is decomposed into two components: between‐ and within‐district segregation. Findings reveal evidence of a significant interaction term: Within‐district segregation is inversely associated with arrests for juvenile violence, but only in metropolitan areas with higher than average levels of between‐district segregation.
