The Development of Peer Interaction in Infancy: Exploring the Dyadic Processes

Peer interaction is an important component of children's social repertoires that is associated with a variety of developmental outcomes and life skills. The present study provides an in‐depth study of early dyadic peer behaviors during the infancy period, during which social competence with peers is first being developed. Results from variable‐centered analyses highlight the effectiveness of behaviors, such as offering objects to peers, and point to the importance of the social context set by a peer's prior social behavior and processes for eliciting peer responses. Findings from person‐centered analyses reveal marked individual differences in the processes through which infants are successful in eliciting responses from their peers, illustrating the presence of multiple pathways to achieving social competence with peers.     

Land-Grant University-Industry Relationships in Biotechnology: A Comparison with the Non-Land-Grant Research Universities1

Abstract The results of a 1986 survey of 185 biotechnology faculty in the land-grant colleges of agriculture are presented. Comparisons are made to a previous survey of biotechnology faculty in nonagricultural research universities. The survey investigates issues raised by industrial involvement in university biotechnology research and the impact of the new biosciences on the agricultural colleges. It was found that college of agriculture biotechnologists have more recently received their highest degrees, show more industrial involvement, and are more positive about the possible benefits of that involvement than their nonagricultural university counterparts. Industrial funding proved to be a significant exogenous variable affecting the activities and attitudes of agricultural college biotechnology faculty. Those with higher levels of industrial funding appear to have lower university productivity.     

Neural Correlates of Human and Monkey Face Processing in 9‐Month‐Old Infants

Behavioral and electrophysiological evidence suggests a gradual, experience‐dependent specialization of cortical face processing systems that takes place largely in the 1st year of life. To further investigate these findings, event‐related potentials (ERPs) were collected from typically developing 9‐month‐old infants presented with pictures of familiar and unfamiliar monkey or human faces in 2 different orientations. Analyses revealed differential processing across changes in monkey and human faces. The N290 was greater for familiar compared to unfamiliar faces, regardless of species or orientation. In contrast, the P400 to unfamiliar faces was greater than to familiar faces, but only for the monkey condition. The P400 to human faces differentiated the orientation of both familiar and unfamiliar faces. These results suggest more specific processing of human compared to monkey faces in 9‐month‐olds.     

The Social Construction of Romantic Relationships in Adolescence: Examining the Role of Peer Networks,Gender, and Race*

Romantic activity is a social psychological phenomenon. Gender, race, and peer networks are key contexts for understanding the social construction of this behavior as gender‐ and race‐based norms structure feelings and behaviors that define “appropriate” romantic activity and peer networks serve as incubators of this activity. With a nationally representative sample of adolescents (N= 8510) drawn from the National Longitudinal Study of Adolescent Health, this study explored the linkages among peer networks, conceptions of idealized romantic relationships and actual romantic relationships, and the ways in which gender and race moderate these associations. Several characteristics of peer networks predicted adolescent attitudes about romantic behaviors as well as actual romantic behavior. Moreover, the linkages among peer networks, romantic attitudes, and romantic behaviors varied by race.     

A Meta‐Analysis of Campaign Contributions' Impact on Roll Call Voting*

Objectives. Conventional wisdom about the link between campaign contributions and roll call votes is that contributions rarely matter because groups tend to give to like‐minded legislators. This meta‐analysis examines the conventional wisdom by analyzing published research on this topic. Methods. More than 30 studies are pooled to produce more than 350 individual tests of the contributions‐roll call link. Extending meta‐regression ( Stanley and Jarrell, 1989 ), a logit meta‐analysis is conducted to summarize the literature and assess the importance of various modeling choices. Results. We find that some, but not all, model specifications have an impact on whether significant results are present. Models that control for friendly giving by including a measure of legislators' ideology and that include more than one contributions variable are less likely to produce significant results. Conclusions. After considering the impact of model choice on study results, we conclude that one‐third of roll call votes exhibit the impact of campaign contributions.     

Rural/Urban Residence,Migration, HIV/AIDS,and Safe Sex Practices among Men in Zimbabwe*

Abstract The AIDS epidemic was initially thought to be primarily an urban phenomenon. However, migration between rural and urban areas has resulted in the spread of the virus to all segments of the population. Prevention efforts continue to focus on the ABCs of AIDS, namely, abstinence among young adults, being faithful within a monogamous relationship, and/or using condoms at each sexual encounter. We examine the effects of residence, migration status, and selected social and demographic variables on the use of these three practices among men in Zimbabwe, a nation experiencing one of the highest HIV/AIDS prevalence rates in the world. Both residence and migration status were found to be significantly related to safe sex practices. Knowledge of a source with easy access to condoms was the strongest predictor of this behavior. Knowledge of prevention methods and experience with persons with AIDS also exerted significant effects, although not always in the manner hypothesized. Possible reasons for the findings and implications for policy are discussed.     

Reports of Conferences,Institutes, and Seminars

In the span of four weeks, from late March to early April 2008, three important technical services conferences were held: the Electronic Resources & Libraries Conference, the New England Technical Services Librarians Conference, and the North Carolina Serials Conference.     

Treatment of psychogenic seizures in adolescents

This article will review the problem of psychogenic seizures in adolescents and the impact of family therapy and individual therapy on treatment. Why particular individuals are prone to psychogenic seizures, the relationship between psychogenic seizures and family dynamics, and unresolved individual issues will be covered. The article will address a selected case, with a specific clinical paradigm for treatment.
