A Qualitative Study of the Formation and Composition of Social Networks Among Homeless Youth

Although social networks are essential for explaining protective and risk factors among homeless youth, little is known about the formation and composition of these groups. In this study, we utilized 19 in-depth interviews with homeless youth to investigate their social network formation, role relationships, housing status, and network member functions. Our findings reveal that the formation of these networks occurred in different ways including meeting network members through others or in specific social situations. The majority of social network members were currently housed and provided various functions including instrumental and social support and protection. Responses from participants provide valuable insight into the formation of social networks and potentially explain their subsequent involvement in risky behaviors.     

The effect of poor parenting on male and female dating violence perpetration and victimization

This study examines the effects of poor parenting on dating violence perpetration and victimization among approximately 900 males and females from the National Longitudinal Survey of Adolescent Health (Add Health). Results revealed that more physical abuse and low parental warmth were linked to greater substance use and higher rates of delinquency. In addition, low parental warmth, more neglect, and greater delinquency had positive direct effects on dating violence perpetration, whereas more physical abuse, low parental warmth, and increased delinquency were all positively associated with dating violence victimization. Finally, delinquency mediated the link between low parental warmth and dating violence perpetration and victimization. The results provide some support for both social learning theory and an antisocial orientation perspective.     

古代占卜比较研究的中国视野

尽管古代地中海地区的占卜习俗研究比其他地方已经拓展了许多空间,但还缺乏＂新世界＂的视界,比如希腊、罗马、亚述和中国对占卜术所作的贡献。中国关于占卜的文献记载极为丰富,可以为占卜比较研究提供一些等值的证据,这是极有可能的,而且将这些证据极富意义地并置起来,又可以避免现行的为比较而比较的神谕研究现实。     

Psychosocial Correlates and Consequences of Adolescents’ Self‐Generated Academic Goals and Appraisals

The current study examined whether characteristics of adolescents (i.e., externalizing problems) and their environments (i.e., social support, adverse childhood experiences) relate to academic goal setting, appraisals, and outcomes. Adolescents (n = 99; 87% Black/African American) 13–16 years old completed baseline interviews, and 80% also completed follow‐up interviews. Adolescents with more externalizing problems set fewer academic goals, and youth with social networks characterized by greater support (and less strain) appraised their academic goals as more supported and achievable. Adolescents’ appraisals of their academic goals, but not how many academic goals they had, predicted grades at follow‐up. Increasing social support (and reducing social strain) may foster adolescents’ positive appraisals of their academic goals, which may promote academic achievement.     

Market Impact on IT Security Spending

Traditionally, IT security investment decisions are made in isolation. However, as firms that compete for customers in an industry are closely interlinked, a macro perspective is needed in analyzing these decisions. We utilize the notions of direct‐ and cross‐risk elasticity to describe the customer response to adverse IT security events in the firm and competitor, respectively, thus allowing us to analyze optimal security investment decisions. Examining both symmetric and asymmetric duopoly cases using a continuous‐time Markov chain (CTMC) model, we demonstrate that optimal IT security spending, expected firm profits and willingness of firms to cooperate on security improvements are highly dependent on the nature of customer response to adverse events. We also examine the investment problem when security attacks on different firms are correlated.
