The goal of the current study was to examine the protective role that maternal media monitoring might have for adolescents. This was done by considering whether styles of media monitoring either directly reduced media use, or whether they buffered the associations between aggressive media use and adolescents’ prosocial behavior, aggression, and delinquency. Participants were 681 adolescents from two cities in the United States (51% female; 73% white), and their mothers, who provided data at two different time points, 2 years apart (when adolescents were roughly ages 13 and 15). Mixture modeling results revealed that mothers used four different styles of media monitoring made up of combinations of active and restrictive monitoring as well as forms of co-use. Styles that included active monitoring and connective co-use (i.e., engaging in media with the intent to connect with children) were directly associated with less media use, and moderated links between adolescents’ media use and behavioral outcomes concurrently but not longitudinally. The discussion was focused on the strength of considering multiple strategies of media monitoring together, and how this approach can inform future research in the area of parental media monitoring.  相似文献

An increasing number of citizens change and adapt their party preferences during the electoral campaign. We analyze which short-term factors explain intra-campaign changes in voting preferences, focusing on the visibility and tone of news media reporting and party canvassing. Our analyses rely on an integrative data approach, linking data from media content analysis to public opinion data. This enables us to investigate the relative impact of news media reporting as well as party communication. Inherently, we overcome previously identified methodological problems in the study of communication effects on voting behavior. Our findings reveal that campaigns matter: Especially interpersonal party canvassing increases voters’ likelihood to change their voting preferences in favor of the respective party, whereas media effects are limited to quality news outlets and depend on individual voters’ party ambivalence.  相似文献

Policymakers have actively pursued urban renewal and dispersal programs to deconcentrate poverty in urban neighborhoods. Relocation strategies lead to new housing opportunities and may encourage employment opportunities for relocated residents if resourceful contacts and job information become more easily available after the move. This study provides an innovative evaluation of the early impacts of involuntary relocation programs in the Netherlands on the housing careers, earnings and employment rates of forced relocatees. It establishes a quasi-experimental design by employing unique longitudinal individual-level population registry data from Statistics Netherlands: forced relocatees are tracked and matched to a control group consisting of similar residents that were not forced to move. A difference-in-difference design shows that forced relocatees are living in less deprived neighborhoods after the move. However, we find no conclusive evidence that this upgrade in housing leads to more socioeconomic opportunities for the forced relocatees.  相似文献

There is widespread evidence that individuals select information that supports their convictions and worldviews. This behavior yields the formation of echo chambers – environments in which an individual’s own political beliefs are repeated and amplified and dissenting opinions are screened out. Recent research demonstrates that social networking sites such as Facebook or Twitter can facilitate this selection into homogenous networks. Using data from a representative nation-wide online survey, we consider the degree to which respondents’ social media networks resemble virtual echo chambers. We then analyze the effect of these social media echo chambers on satisfaction with democracy among Democrats and Republicans in the aftermath of the 2016 US elections. Our findings reveal that virtual echo chambers boost democratic satisfaction among Republicans but they do not have an effect on system support by self-identified Democrats. Our paper therefore adds to a growing literature linking online behaviors to mass attitudes about politics.  相似文献

Climate change adaptation refers to altering infrastructure, institutions or ecosystems to respond to the impacts of climate change. Least developed countries often lack the requisite capacity to implement adaptation projects. The Global Environment Facility’s Least Developed Countries Fund (LDCF) is a scheme where industrialised countries have disbursed $934.5 million in voluntary contributions to support 213 adaptation projects across 51 least developed countries. But how effective are its efforts—and what sort of challenges have arisen as it implements projects? To provide some answers, this article documents the presence of four “political economy” attributes of adaptation projects—processes we have termed enclosure, exclusion, encroachment and entrenchment—cutting across economic, political, ecological and social dimensions. Based on extensive field research, we find the four processes at work simultaneously in our case studies of five LDCF projects being implemented in Bangladesh, Bhutan, Cambodia, the Maldives and Vanuatu. The article concludes with a discussion of the broader implications of the political economy of adaptation for analysts, program managers and climate researchers at large. In sum, the politics of adaptation must be taken into account so that projects can maximise their efficacy and avoid marginalising those most vulnerable to the impacts of climate change.  相似文献

ABSTRACT

This article examines the role of India’s states in shaping the implementation and framing of social policy within India’s federal system. Since the 2000s, the central government has overseen a substantial expansion of social welfare policies partly through a new push toward rights-based social provision. Yet, it is India’s states that are both responsible for an increasing proportion of total public expenditure on social welfare provision as well as determining the nature and effectiveness of that provision across space. Drawing on a comparative research program across pairs of Indian states, three critical factors explaining how state-level political environments shape social policy are identified: the role of policy legacies in shaping policy frames; the role of social coalitions underpinning political party competition; and the role of political leaders in strengthening state capacity to achieve program goals.  相似文献

Crime victim–police interface and registration of crime are the early and fundamental interactions in the criminal justice system. The process of lodging a complaint is marked by the pain of victimization, sharing of information, and expectation of quick remedial action from the police. The nature and quality of experience of the victim and outcomes impact the level of satisfaction with services of police. Through a survey of victims of property crimes, in different areas of a state in India, the author examines the impact of procedural justice and outcomes on victim satisfaction. The study illuminates the outcome oriented expectations of the victim, and the unique dynamics of victim–police interaction, which strains the legal ethical framework of the criminal justice system.  相似文献

A number of studies have shown that arts and cultural programs offer multifarious benefits to individuals and communities. However, there has been little discussion in the public management literature regarding access to cultural programs for people with limited disposable income. Although the arts industry is increasingly emphasizing the importance of expanding cultural access for all, we know little about what drives individual nonprofit organizations’ strategies. This article draws on benefits theory and resource dependence theory to explore the relationships between different types of revenue and the extent to which performing arts nonprofits offer free access. The authors use a unique data set compiled by DataArts to test how various types of revenue influence accessibility to the arts and find that performing arts nonprofits receiving grants from local governments, foundations, and corporations offer more free access. The article concludes with a discussion of study implications and an application of benefits theory to other types of nonprofits.  相似文献

This article seeks to explain why electoral support for the Venezuelan opposition has increased substantially, using Venezuelan public opinion survey data from LAPOP and an opt‐in sample collected through the online vote advice application Brújula Presidencial Venezuela. It analyzes why Venezuelans who had either voted for Chávez or abstained in 2006 defected and started to support the opposition in subsequent elections. It proposes several reasons: negative voter evaluations of the economy, concern for public safety, and dissatisfaction with Venezuelan democracy. While the finding that negative policy evaluations boost support for the opposition aligns with theoretical expectations, this study finds a strong relationship between having different evaluations of the quality of democracy and supporting Chávez, which shows that the advocacy of two competing visions of democracy by the incumbent and the opposition also affects voting patterns in Venezuela.  相似文献
