Increased recognition of the consequences associated with child maltreatment has led to greater emphasis on its prevention. Promising maltreatment prevention strategies have been identified, but research continues to suffer from methodological limitations and a narrow focus on select prevention models. This investigation uses data from the Chicago Longitudinal Study to examine mediating mechanisms that link the Chicago Child-Parent Center preschool program to a reduction in overall child maltreatment and, more specifically, child neglect. We use structural equation modeling to test child, family, and school measures hypothesized to mediate the effects of CPC participation on maltreatment and neglect. Results indicate that a substantial proportion of the program's impacts can be accounted for by family support processes, including increased parent involvement in school and maternal educational attainment as well as decreased family problems. The CPC program's association with reduced school mobility and increased attendance in higher-quality schools also significantly mediated its effects on maltreatment and neglect. Further, a decrease in troublemaking behavior contributed modestly to mediating the program's association with maltreatment but not neglect. We discuss the implications of these results for the field of maltreatment prevention. 相似文献

The presence of an underwriting profit cycle in property/liability insurance has become a stylized fact. Models of this'underwriting cycle'imply that the insurance market is governed by two regimes, as capacity is constrained or not. We apply the smooth transition regression model to insurance industry data for 1934–1993 to test for a regime shift. We find a rapid shift between two distinct regimes with different dynamics. When capacity is not restricted, we find no evidence of a cycle. The cycle is present in periods when capacity is restricted, immediately following World War II and after 1968. The underwriting cycle appears to be a recent phenomenon. 相似文献

Government expansion of child care services is based on the assumption that both parents are employed (the adult worker model) and make cost‐benefit calculations in choosing child care (the rational economic choice model). This paper addresses this assumption, based on research examining mothers' assessments of appropriate child care. These assessments involve complex moral and emotional decisions around their own and their children's needs, and differ between social groups. On this basis, we conclude that the assumptions underlying current child care expansion policy are inadequate, and that the mere expansion of services is not enough. 相似文献

Anal intercourse poses a greater risk for human immunodeficiency virus (HIV) transmission than vaginal intercourse, and in recent years there has been a growing understanding that heterosexual anal intercourse (HAI) is not uncommon. However, the majority of the anal intercourse literature has focused on men who have sex with men. The little research on HAI has mostly looked at women, with limited work among men. This analysis examined the association between HAI and high-risk behaviors (N = 1,622) and sexual sensation seeking (N = 239) in a sample of men recruited from 2001 to 2012 in Long Beach, California. Almost half of the sample was non-Hispanic Black. The median age was 42 years, 42% were homeless, and 20% reported recent HAI. Men who reported HAI were likely to be Hispanic, were likely to be homeless, had a male partner, engaged in sex exchange, and used cocaine or amphetamines during sex. Men who reported HAI scored higher on the Sexual Sensation Seeking scale. This research supports other work showing the relationship between HAI and high-risk behaviors. More important, it contributes new knowledge by demonstrating the association between HAI and sexual sensation seeking. This research highlights the importance of personality traits when trying to understand sexual behavior and when developing HIV prevention interventions. 相似文献
