Education, empowerment and community based structural reinforcement: an HIV prevention response to mass incarceration and removal

In the context of US urban jails, incarceration is often seen as an opportune intervention point for prevention interventions in public health. For the detained individual, it is an opportunity to reflect on individual choices and the potential for changes in one's life course. For population focused public health professionals, jail detention facilities represent a concentration of health risks, and an opportunity to have an impact on a significant portion of those at risk for HIV and other health concerns. This paper presents an innovative education and empowerment model that bridges across jail walls, beginning on the inside, and continuing on the outside of jail where individuals continue to be challenged and supported toward positive health and social choices. The intervention also seeks to foment community activism in the communities to which jail detainees return, thus aiming to have a structural impact. This paper examines both the intervention model and the challenges of examining the effectiveness claims for the intervention at multiple levels.     

志愿者动机之社会和文化起源——六国大学生调查情况比较

虽然有关志愿者活动的参与以及志愿者动机(Motivationsto Volunteers,以下简称MTV)的研究已经受到许多国家(尤其是美国)的持续关注,但是,从文化和政治背景来解析的研究却鲜见。本文对志愿者活动的社会起源论和信息传递论这两种理论进行了比较,阐述了不同国家志愿者动机的差异,着重分析了来自6个国家具有不同文化背景的5,794名学生各自的反应。所得到的结果有力地支持了信息传递论,与此同时却淡化了社会起源论。文章得出结论:参与志愿者活动系个人的决定,更多地受个人影响,当然某种程度上也受到巨大的社会力量的影响。     

Patterns of Aggressive Behavior and Peer Victimization from Childhood to Early Adolescence: A Latent Class Analysis

The developmental period characterized by the transition from childhood and elementary school to early adolescence and middle school has been associated with increases in aggressive behavior and peer victimization. Few longitudinal studies, however, have examined the stability of aggression and victimization during this critical transition. This study uses latent class analysis (LCA) to examine patterns of aggressive behavior and victimization during the transition to middle school among urban, public school students (N = 458; Girls = 53%; Latino/a = 53%; M age at t1 = 10.2 years). Independent LCA models were conducted using self-reported data assessing subjects’ involvement in aggressive conduct and victimization during the spring semesters of grades four, five, and six. Elementary school students in the fourth grade initially belonged to one of four groups identified as aggressor, victim, aggressor-victim, and uninvolved latent classes. Contrary to prior research, membership in these classes changed significantly by the time students completed their first year of middle school with most youth participating in episodes of aggression and victimization during the transition. Six common paths that describe patterns of aggressive behavior and victimization from the last two years of elementary school to the first year of middle school were found. Findings are discussed in the context of social dominance theory and prior research that has found greater stability in aggression and victimization among early adolescents.     

The Influence of the Social Bond on Self-control at the Moment of Decision: Testing Hirschi’s Redefinition of Self-control

Hirschi (2004) redefined self-control as the tendency to consider the “full range” of potential costs relevant to a criminal act, suggesting that such costs vary in number and salience based on one’s level of self-control. He also suggested self-control, as expressed at the moment of decision, was influenced by the individual’s level of social bonding; those with fewer bonds would exhibit less self control by considering fewer costs and finding them less salient when making a decision. This study presents an initial attempt to examine Hirschi’s theoretical statement linking concepts from the two theories. Presented with a hypothetical drunk driving scenario, participants were asked to identify perceived costs and salience as a measure of self-control, as Hirschi (2004) suggested. Results support Hirschi’s assertion demonstrating that the social bond impacts offending likelihood through its relationship to self-control expressed within the decision. Future theoretical and empirical directions are outlined.     

Growing Stem Cells: The Impact of Federal Funding Policy on the U.S. Scientific Frontier

This paper articulates a citation‐based approach to science policy evaluation and employs that approach to investigate the impact of the United States’ 2001 policy regarding the federal funding of human embryonic stem cell (hESC) research. We evaluate the impact of the policy on the level of U.S. hESC research, the U.S. position at the knowledge frontier, and the strategic response of U.S. scientists. Consistent with recent research on the science of science and innovation policy, we employ a difference‐in‐differences approach using bibliometric data with the aim of analyzing the causal impact of the policy on cumulative research. Our estimates suggest that in the aftermath of the 2001 policy, U.S. production of hESC research lagged 35 to 40 percent behind anticipated levels. However, this relative decline was largely concentrated in the years 2001 to 2003 and ameliorated over time. The rebound in U.S. hESC research after 2003 was driven by contributions by researchers at elite U.S. institutions and U.S. researchers who collaborated with international partners. The results suggest that scientists respond strategically to research funding restrictions and that modest science policy shifts can have a significant influence on the within‐country composition of research and the pattern of global research collaboration.
