A large body of research has identified correlates of risky sexual behavior, with depressive symptoms and marijuana use among the most consistent psychosocial predictors of sexual risk. However, substantially less research has examined the relationship between these risk variables and adolescent risky sexual behavior over time as well as the interaction of these individual-level predictors with family-level variables such as parenting factors. Additionally, most studies have been restricted to one index of risky sexual behavior, have not taken into account the complex role of gender, and have not controlled for several of the factors that independently confer risk for risky sexual behavior. Therefore, the current study investigated the association between depressive symptoms and parameters of parenting on marijuana use, number of sexual partners and condom usage measured 9 months later for both boys and girls. Participants were 9th and 10th grade adolescents (N = 1,145; 57.7 % female). We found that depressive symptoms may be a gender-specific risk factor for certain indices of risky sexual behavior. For boys only, marijuana use at Time 2 accounted for the variance in the relationship between depressive symptoms at Time 1 and number of partners at Time 2. Additionally, strictness of family rules at Time 1 was associated with the number of partners with whom girls engaged in sex at Time 2, but only among those with lower levels of depressive symptoms at Time 1. Results from the current investigation speak to the utility of examining the complex, gender-specific pathways to sexual risk in adolescents. Findings suggest that treatment of mental health and substance use problems may have important implications in rates of risky sexual behavior and, conceivably, controlling the high rates of serious individual and public health repercussions.  相似文献

The current study evaluated a range of social influences including misdemeanor arrests, drug arrests, cocaine consumption, alcohol consumption, firearm availability, and incarceration that may be associated with changes in gun-related homicides by racial/ethnic group in New York City (NYC) from 1990 to 1999. Using police precincts as the unit of analysis, we used cross-sectional, time series data to examine changes in Black, White, and Hispanic homicides, separately. Bayesian hierarchical models with a spatial error term indicated that an increase in cocaine consumption was associated with an increase in Black homicides. An increase in firearm availability was associated with an increase in Hispanic homicides. Last, there were no significant predictors for White homicides. Support was found for the crack cocaine hypotheses but not for the broken windows hypothesis. Examining racially/ethnically disaggregated data can shed light on group-sensitive mechanisms that may explain changes in homicide over time.  相似文献

Traditional economic theory posits that people make decisions by maximizing a utility function in which all of the relevant constraints and preferences are included and weighed appropriately. Behavioral economists and decision-making researchers, however, are interested in how people make decisions in the face of incomplete information, limited cognitive resources, and decision biases. Empirical findings in the areas of behavioral economics and judgment and decision making (JDM) demonstrate departures from the notion that man is economically rational, illustrating instead that people often act in ways that are economically suboptimal. This article outlines findings from the JDM and behavioral-economics literatures that highlight the many behavioral impediments to saving that individuals may encounter on their way to financial security. I discuss how behavioral and psychological issues, such as self-control, emotions, and choice architecture can help policymakers understand what factors, aside from purely economic ones, may affect individuals' savings behavior.  相似文献

People who want to tackle tough social problems and achieve beneficial community outcomes are beginning to understand that multiple sectors of a democratic society—business, nonprofits and philanthropies, the media, the community, and government—must collaborate to deal effectively and humanely with the challenges. This article focuses on cross-sector collaboration that is required to remedy complex public problems. Based on an extensive review of the literature on collaboration, the article presents a propositional inventory organized around the initial conditions affecting collaboration formation, process, structural and governance components, constraints and contingencies, outcomes, and accountability issues.  相似文献

The Clean Air Act (CAA) controls routine emissions at petroleum refineries, by creating limits and penalties for excess emissions. The CAA offers provisions for upset events, air emissions released because of unforeseen or unavoidable circumstances, if companies report the emissions and take corrective action. States enforce upset event rules and many states provide exemptions for a variety of circumstances, which may allow upset emissions to become a substantial, yet mostly unregulated source of emissions. We catalog the quantity and type of emissions generated during upset events at 18 Texas petroleum refineries from 2003 to 2008. We find that upset events occur frequently at these facilities and are collectively large in magnitude, emitting a combined total of 75 million lbs of emissions. In a select number of cases, single upset events exceeded annual emissions reported to the Toxics Release Inventory. Future research should assess the accuracy of upset event reporting and impact of upset events on environmental health.  相似文献

An increasingly predominant strategy used by organizations seeking to increase support for gay marriage is to personalize the issue by focusing on individuals in the LGBT community. However, competing theoretical traditions (e.g., Allport??s contact theory, group threat, implicit bias) raise questions about whether this strategy has the desired effect. This paper presents results from an original field experiment conducted in coordination with a marriage equality organization. Callers who self-identified as a member of the LGBT community were less effective in soliciting donations compared to callers who did not self-identify, suggesting that personalization has a negative effect on persuasion efforts. The findings cut against the grain of the Allport (The nature of prejudice, 1954) hypothesis and have important implications for social advocacy organizations in terms of rhetorical and message strategy.  相似文献

Bilateral symmetric bone nodules were observed in the anterolateral first ribs of an infant with shaking injuries at autopsy. The location prompted diagnostic considerations of healing fractures versus anomalous articulations with pseudarthroses. The forensic pathologist worked with forensic anthropologists and pediatric radiologists to evaluate autopsy findings and compare premortem and postmortem X‐rays. Gross examination of the bones by the pathologist and anthropologists confirmed bilateral, callus‐like bone nodules in first‐rib locations associated with pseudarthroses. Histologic examination of one of the bones further showed features most consistent with pseudarthrosis, not a healing fracture. Radiologists then compared multiple premortem and postmortem radiographs that showed no remodeling of the bone over a 2‐week interval between the time of injury and death, which would be unexpected for a healing fracture in an infant. This multidisciplinary approach resulted in the appropriate diagnosis of pseudarthroses due to anomalous articulations, an uncommon finding in forensic pathology.  相似文献

After several decades of research on how the criminal justice system handles reports of sexual assault, the attrition of cases at the police and prosecutor stages continues to draw the attention of policy makers, victim advocates, and academics. Such attrition has implications for thousands of victims and their alleged offenders each year. Current estimates show that significant rates of attrition persist and vary across jurisdictions. Recent work in two jurisdictions reveals a pattern of exceptional clearances being used to close sexual assault cases reported to the police and that prosecutors are weighing in at the arrest stage. Broadening this analysis we use incident data from a multitude of jurisdictions that report to the National Incident Based Reporting System (NIBRS) in combination with data from other law enforcement sources to investigate how legal and extra-legal incident factors as well as agency factors differentiate the decision to clear cases by exceptional means from clearance by arrest. We find that agency, legal, and extra-legal factors predict the use of exceptional clearance relative to arrest and discuss how these findings suggest a downstream orientation in case processing.  相似文献

The neoliberal direction of social policy under New Zealand’s fifth National government (2008–) is demonstrated in its 2012 White Paper for Vulnerable Children. This document advocates increased monitoring and policing of welfare populations and the downgrading of child protection policy to a technical administrative system for managing ‘risky’ families. The White Paper’s release came soon after the coroner’s report into the deaths of the ‘Kahui twins’, which were treated by the media as a shocking case of child abuse, and exemplified the media’s use of a fantasy of a ‘savage’ Maori welfare underclass in reporting cases of child abuse. Drawing on Isin’s analysis of ‘governing through neurosis’, this article explores how these media and policy discourses reinforce normative patterns of neoliberal citizen subjectivity by offering compelling pathways out of anxiety that re-route citizens’ anxiety over child abuse in support of neoliberal modes of citizen subjectivity.  相似文献
