The United States Supreme Court’s recent decision relating to violent video games revealed divisions within the scientific community about the potential for negative effects of such games as well as the need for more, higher quality research. Scholars also have debated the potential for violent games to have positive effects such as on visuospatial cognition or math ability. The current study sought to extend previous literature by using well-validated clinical outcome measures for relevant constructs, which have generally been lacking in past research. Cross-section data on aggression, visuospatial cognition, and math achievement were available for a sample of 333 (51.7 % female) mostly Hispanic youth (mean age = 12.76). Prospective 1-year data on aggression and school GPA were available for 143 (46.2 % female) of those youth. Results from both sets of analysis revealed that exposure to violent game had neither short-term nor long-term predictive influences on either positive or negative outcomes. A developmental analysis of the cross-sectional data revealed that results did not differ across age categories of older children, preadolescents or adolescents. Analysis of effect sizes largely ruled out Type II error as a possible explanation for null results. Suggestions for new directions in the field of video game research are proffered. 相似文献

Previous research has shown that voters’ perception of electoral fairness has an impact on their attitudes and behaviors. However, less research has attempted to link objective measurements of electoral integrity on voters’ attitudes about the democratic process. Drawing on data from the Comparative Study of Electoral Systems and the Quality of Elections Data, we investigate whether cross-national differences in electoral integrity have significant influences on citizens’ level of satisfaction with democracy. We hypothesize that higher levels of observed electoral fraud will have a negative impact on evaluations of the democratic process, and that this effect will be mediated by a respondent’s status as a winner or loser of an election. The article’s main finding is that high levels of electoral fraud are indeed linked to less satisfaction with democracy. However, we show that winning only matters in elections that are conducted in an impartial way. The moment elections start to display the telltale signs of manipulation and malpractice, winning and losing no longer have different effects on voter’s levels of satisfaction with democracy. 相似文献

Since the mid‐1990s, formal scientific risk management has been codified at all levels of food safety governance in affluent states: firm‐level standards, national regulation, and international law. Developing countries' access to affluent importers and power in international standard‐setting fora now hinges on their scientific capacity. This article explores the consequences of these developments in India, which moved quickly from resistance to acquiescence, and then later to mobilization around narratives of scientific risk management's local benefits. The case suggests a two‐stage model of scientization among developing countries: (1) coercive and competitive mechanisms drive adoption of science‐based governance models, and (2) as local actors mobilize to meet foreign demands, they attach their own interests and agendas to science‐based reforms. The outcome is a set of rational myths about the benefits of scientization. The article draws on content analysis of organizational, policy, and news documents and a small set of interviews with highly placed pubic officials and industry representatives. 相似文献

This study examined community-based clinicians’ (N = 294) attitudes, background/experiences, values, and knowledge relating to issues of co-occurring disorders, which occur at a high rate among adolescents involved in the juvenile justice system. Study results reveal that clinicians self-rate their clinical values and attitudes at or above the expected level of competency, but they concede that their skill and knowledge levels are not adequate. Comparison measures reveal that employment setting conditions, geographic region, hours worked per week, and strongly held convictions about the importance of integrated mental health and substance use disorders service delivery distinguish clinicians’ co-occurring disorders knowledge levels. Implications are offered. 相似文献

This multisite assessment of five, court-affiliated parent education programs incorporates information from 3,000 exit surveys by attendees, 602 telephone interviews with willing parents six months later, comparisons with 145 divorcing parents who did not attend a program, and reviews of court activity. Parents report high levels of satisfaction with the programs and credit them with helping to sensitize them to their children's needs and making visitation more successful and enjoyable. Although attendees report better compliance with divorce decrees, comparable proportions of parents in treatment and comparison groups report conflict over child custody and access, and a review of court files shows identical litigation patterns for both groups over a four-year period of time . 相似文献

ABSTRACTPolicies on transnational labor migration do not consider workers' needs as parents or the rights and welfare of their children, including a child's right to an official identity through birth registration. A study of birth-registration decision making by migrant parents in Lombok, Indonesia underscored the need for targeted responses to uniquely challenging circumstances and priorities of migrant parents. Free birth registration through birthing and health centers and village-level leaders can overcome problems of decentralized implementation of national strategies and an exploitive registration brokerage industry, mitigating risks of de facto statelessness for children and a multigenerational pattern of undocumented and unsafe migration. 相似文献
