This study examined relations among neighborhood disadvantage, parent-child conflict, deviant peer involvement in the neighborhood, and early-starting antisocial trajectories. Antisocial group patterns were identified in 218 low-income boys followed from ages 5 to 11, and neighborhood and family variables were evaluated as predictors in early and middle childhood. Four trajectory groups emerged...

Although neighborhood stressors have a negative impact on youth, and social support can play a protective role, it is unclear what types and sources of social support may contribute to positive outcomes among at-risk youth. We examined the influences of neighborhood disadvantage and social support on global self-worth among low-income, urban African American youth, both concurrently and longitu...

Two studies examined how the relevance of group identity influences two psychological mechanisms of collective action: Emotion- and problem-focused coping with collective disadvantage. Extending Van Zomeren, Spears, Fischer, and Leach's (2004) integrative theoretical model of coping with collective disadvantage, we predicted that when group identity is more relevant to disadvantaged group membe...

Transverse vibrations of Timoshenko type beams carrying a concentrated mass have been investigated. Both ends of this mass-beam system have simply supports. Hamilton Principle has been used in order to derive equation of motion . For this coupled differential equations, approximately solutions have been searched by means of Method of Multiple Scales(a perturbation method). These solutions consi...

We use simulated merger trees of galaxy-cluster halos to study the effect of the halo concentration distribution on strong lensing and X-ray emission. Its log-normal shape typically found in simulations favors outliers with high concentration. Since, at fixed mass, more concentrated halos tend to be more efficient lenses, the scatter in the concentration increases the strong-lensing optical dep...

BACKGROUND 'Place' matters in understanding prevalence variations and inequalities in child maltreatment risk. However, most studies examining ecological variations in child maltreatment risk fail to take into account the implications of the spatial and temporal dimensions of neighborhoods. In this study, we conduct a high-resolution small-area study to analyze the influence of neighborhood cha...

The purpose of the present study was to examine relations among multiple child and family protective factors, neighborhood disadvantage, and positive social adjustment in a sample of 226 urban, low SES boys followed from infancy to early adolescence. The results indicated that child IQ, nurturant parenting, and parent-child relationship quality, measured in early childhood, were all significant...
