The Role of Aggressive Peer Norms in Elementary School Children’s Perceptions of Classroom Peer Climate and School Adjustment

Journal of Youth and Adolescence - Although prior research has indicated that peer norms for aggression enhance the spread of aggression in classrooms, it is unclear to date how these norms relate...     

Socially Demoralizing Environments and the Development of the Street Code from Childhood to Emerging Adulthood

This study examines hypotheses regarding patterns of developmental change in street code commitment from childhood through emerging adulthood. It tests whether street code commitment demonstrates developmental stability or if it fluctuates in response to evolving socially demoralizing conditions. Latent growth curve and parallel process models are applied to longitudinal data from an African American sample. Confirmatory factor analysis tests the degree to which neighborhood violence, peer processes, and family hostilities combine to form a latent construct of socially demoralizing environments. Analysis also tests measurement invariance across the study assessment periods. Street code commitment demonstrates a non-linear growth pattern across time. Commitment increases in childhood, peaks in late adolescence, and declines in emerging adulthood. Exposure to demoralizing social environments demonstrates a similar pattern of change characterized by a peak in adolescence followed by a gradual decline. Harsh childhood social environments affect the initial levels but not the growth of the street code. Street code commitment fluctuates in response to contemporaneous environmental conditions. The street code is malleable from childhood through emerging adulthood. Commitment to the street code is not a stable product of socialization or early childhood social environmental exposures. The degree to which individuals embrace the code is largely a function of their current social environment.     

FEDERAL LEGISLATION AND INTEREST FORMATION: THE CASE OF IMPUTED INTEREST GROUPS

This paper examines an impact of federal legislation on the formation of political interests; it identifies and defines a phenomenon we have labeled imputed interest groups . The interest groups can be seen when federal legislation makes benefit packages that serve as incentives to interest formation and ties interest groups to the maintenance of these benefit packages. Identification of imputed interest groups necessitates a re-examination of subgovernments, service deliverer-recipient relationships, and policymaking in a federal system.     

Human subjects protections in biomedical enhancement research: assessing risk and benefit and obtaining informed consent

The protection of human subjects in biomedical research relies on two principal mechanisms: assessing and comparing the risks and potential benefits of proposed research, and obtaining potential subjects' informed consent. While these have been discussed extensively in the literature, no attention has been paid to whether the processes should be different when the objective of an experimental biomedical intervention is to improve individual appearance, performance, or capability ("enhancement research") rather than to prevent, cure, or mitigate disease ("health-oriented research"). This essay examines this question in order to ensure that subjects in biomedical enhancement research receive adequate protection.
