HIV Testing Among Heterosexual Young Adults: The Influence of Partners' Risk Behaviors and Relationship Dynamics

Using relational theory and survey data from the Toledo Adolescent Relationships Study (n = 665), this article examined whether individuals were tested for HIV while intimately involved in a current or recent heterosexual relationship. The analyses included the respondent's and partner's sexual risk factors (non-exclusivity and lifetime number of partners), relational variables, prior testing, and demographic characteristics. It was found that 39% of respondents had an HIV test while involved in their current or most recent sexual relationship, and women (47%), compared with men (29%), were significantly more likely to have been tested. Whereas some predictors operated similarly (number of sex partners and pressured to have sex), others displayed significant gender differences (partner's sexual exclusivity, sexual communication difficulties, and pregnancy), particularly related to women's testing behaviors. Excerpts from qualitative interviews with male respondents suggested that some relational dynamics, not well reflected in relational theory, played a role in their testing. Results highlight the need to consider gendered dynamics when targeting young adults for routine HIV testing.     

Job-Seeking Behavior in Young Adults: Do Unemployment Insurance Benefits Hurt Job Search Efforts?

ABSTRACT. The purpose of the present study was to evaluate the association between extended unemployment insurance (UI) benefits and young adults’ job-seeking behavior. In particular, the study evaluated if the extension of UI benefits to 99 weeks in 2008 had direct effects on job search efforts. Three waves (2007–2009) of data (N = 915) from the National Longitudinal Survey of Youth were analyzed using multiple regression models to assess the association of UI benefits to young adults’ job search efforts. Additionally, the homogeneity of slope coefficients of the UI benefit on job search effort was evaluated across 3 years using an analysis of covariance (ANCOVA). The results of regression analyses suggest that UI benefits were negatively associated with job search efforts for 2007 and the pooled sample of 2007 to 2009, but the relationship was not significant for 2008 and 2009. The results of the ANCOVA suggest that the UI benefit extension of 2008 did not have any negative association with job search efforts. Future studies should explore the subjective experiences and decisions young adults make in consideration of unemployment, UI benefits, and job search efforts.     

Elder abuse and neglect in South Africa: a case of marginalization, disrespect, exploitation and violence

The problem of elder abuse and neglect in South Africa is widespread, but the definition of abuse remains problematic. An expanded typology is needed to classify certain types of abuse reported commonly, such as marginalization, disrespect, exploitation and violence. The history of elder abuse and responses is traced, relevant legislation and selected intervention programs are reviewed, and research and the status of elder abuse are evaluated. Interventions to address sociostructural factors that impact elders' settings, increase their vulnerability, and diminish their ability to realize human rights can contribute to an improvement in their condition and a reduction in abuse and rights violations in the long-term.     

Immigration policies and trends: A comparison of Canada and the United States

This paper discusses recent migration to North America with reference to the 1962 and 1967 Canadian immigration regulations and the 1965 United States Immigration and Nationality Act. Despite the similar emphasis on manpower and kinship criteria as the basis for the admission of immigrants, differences between Canada and the United States exist with respect to the importance of immigration for the respective economies, the organization of immigration, the formal regulations, and the size and composition of migrant streams. After an examination of the volume, origin, and occupational composition of immigration to Canada and the United States, flows between the two countries are studied. The paper concludes with a scrutiny of changes in immigration regulations which are pending in both countries.     

“The More You Gesture,the Less I Gesture”: Co-Speech Gestures as a Measure of Mental Model Quality

Studies in the literature have revealed that a speaker’s co-speech gestures favor the construction of a complete and articulated mental model of the discourse by the listener; moreover, from the literature on co-speech gestures we know that they help the speaker to organize the stream of thought. Given these data, we hypothesized that a person who listens to a discourse accompanied by gestures would produce fewer co-speech gestures in recollecting the discourse compared to a person who listens to a discourse not accompanied by gestures. The analysis of the co-speech gestures produced by the participants in two experiments while recollecting the content of a discourse confirmed our predictions.     

The Enduring Significance of Racism: Discrimination and Delinquency Among Black American Youth

Prominent explanations of the overrepresentation of Black Americans in criminal justice statistics focus on the effects of neighborhood concentrated disadvantage, racial isolation, and social disorganization. We suggest that perceived personal discrimination is an important but frequently neglected complement to these factors. We test this hypothesis with longitudinal data on involvement in general and violent juvenile delinquency in a sample of Black youth from a variety of communities in 2 states. We examine the direct effects of concentrated disadvantage and racial isolation and the direct and mediating effects of social organization, support for violence, and personal discrimination. Consistent with our hypothesis, perceived personal discrimination has notable direct effects on both general and violent delinquency and is an important mediator between neighborhood structural conditions and offending; moreover, its effects exceed those associated with neighborhood conditions.     

Using Object Knowledge in Visual Tracking and Reaching

Nine‐month‐old infants were presented with an engaging and challenging task of visually tracking and reaching for a rolling ball that disappeared and reappeared from behind an occluder. On some trials, the infant observed the experimenter place a barrier on the ball's track; the barrier remained partially visible above the occluder throughout the remainder of the trial. When the task involved only predictive tracking, infants' anticipatory gaze shifts were faster when no barrier was present. When the task involved both tracking and reaching, there were more reaches when no barrier was present. If the infant reached, the timing and extension of the reach and the accompanying gaze shift did not differ with regard to the barrier. Because catching the ball was quite difficult for these infants, task demands interfered with the integration of visual information and visuospatial reasoning about the barrier with the reaching action.     

Integrating commercial and residential pickup and delivery networks: A case study

This paper presents a strategic analysis of the network design problem faced by pickup and delivery companies operating in metropolitan areas and serving two or more classes of customers. The focus is on a division that treats commercial and residential customers separately, a situation motivated by their respective geographic densities and the size and frequency of their demand. In constructing driver work areas, it is necessary to take into account expected demand, vehicle capacity, time on the road, and the aspect ratio of the individual territories. This leads to a capacitated clustering problem with side constraints that has been the subject of intense research over the last decade.
