This paper explores the relationship between public housing, health outcomes, and health behaviors among low-income housing residents. While public housing can be a dangerous and unhealthy environment in which to live, the subsidized rent may free up resources for nutritious food and health care. In addition, public housing may be of higher quality than the available alternatives, it may provide easier access to health clinics willing to serve the poor, and it may link residents to social support networks, which can improve mental health and the ability to access higher-quality grocery stores. To test whether there is a "back-door" health benefit to the public housing program, we analyze data from the Fragile Families and Child Wellbeing Study. We minimize the effects of selection into public housing with controls and instrumental variables estimation and find that the results are somewhat sensitive to the instrumental variable used, and thus, we conclude that we are unable to detect a robust health benefit from public housing for our measures of health. However, we do find some evidence that public housing residency has mixed effects on domestic violence, increases obesity, and worsens mothers' overall health status. 相似文献

Cannabinoid hyperemesis syndrome (CHS) is one of the more clinically challenging effects of cannabis consumption. It is characterized by cyclic attacks of nausea and vomiting in chronic cannabinoid users and learned behavior of compulsive hot bathing. The deaths of a 27‐year‐old female, a 27‐year‐old male, and a 31‐year‐old male with a history of CHS are reported. The decedents had a history of cyclical nausea and vomiting, chronic cannabinoid use and negative laboratory, radiological and endoscopic findings. All presented to the emergency department with nausea and vomiting in the days preceding death and were treated symptomatically. Toxicological analysis revealed tetrahydrocannabinol in postmortem blood. The cause of death of two of the three cases was attributed to CHS. CHS was appreciated in the third case but was not the cause of death. These three cases demonstrate the importance of recognizing CHS as a potential cause or contributing factor to death in cannabinoid user. 相似文献

Prior empirical research on intimate partner violence (IPV) in adolescence and young adulthood often focuses on exposure to violence in the family-of-origin using retrospective and cross-sectional data. Yet individuals’ families matter beyond simply the presence or absence of abuse, and these effects may vary across time. To address these issues, the present study employed five waves of longitudinal data from the Toledo Adolescent Relationships Study (TARS) to investigate the trajectory of IPV from adolescence to young adulthood (N = 950 respondents, 4,750 person-periods) with a specific focus on how familial factors continue to matter across the life course. Results indicated that family-of-origin violence and parent-child relationship quality were independent predictors of IPV. The effect of parent-child relationship quality on IPV also became greater as individuals aged. These results have implications for policies targeted at reducing IPV. 相似文献

Despite their widely recognized benefits, integrative approaches to negotiation have seldom been effectively used in interorganizational negotiations. This study analyzes the 1987–1995 Korea–United States Trade Negotiations, identifying elements in those talks that could have moved the negotiations in a more integrative direction. The role of building relationships — especially between key negotiators — is examined. Informal negotiations between the key negotiators from both sides were crucial in building such relationships, which helped both sides create solutions for mutual gains. This process was realized, inter alia, by the dual role that the key negotiators took on as negotiators and as mediators. 相似文献
