During waves of contention, international media attention can be of crucial importance for activists and protest participants. However, media attention is a scarce resource and the competition over news coverage is high. While some emphasize the agenda-setting power of news outlets and argue that receiving coverage is determined by factors outside the protest movement, others suggest a dynamic relationship between media attention and activism where social movement organizations are assumed to have some agency to make it to the news. In this article, we contribute to the latter and analyze how protest can endogenously trigger more coverage. Building on insights from communication science, we argue that widely covered protests attract media attention and temporarily lower the selection threshold for subsequent incidents. Using fine-grained data on anti-regime protest in all authoritarian countries between 2003 and 2012, we find robust empirical evidence for this hypothesis. We also show that this effect becomes weaker and eventually disappears with increasing spatial and temporal distance from a highly salient event. These findings are important for research in contentious politics, since they allow us to gauge the extent to which protest activity on the ground may under certain circumstances be overreported in the media.  相似文献

Synthesizing several theories about the likely impact of case reports in the news, we propose that the impact of featuring identified victims in a news story is contingent on the degree of similarity between the audience member and the identified victims. We execute a population-based survey experiment involving immigration policy to examine our theory. Our results suggest that featuring specific, identified victims in a news story will promote more supportive policy opinions than otherwise identical stories about unidentified victims, but only when the victim is highly similar to the audience member. Conversely, case reports featuring identified people who are dissimilar to the audience member will decrease the extent to which the story encourages victim-supportive policy attitudes. Overall, our experimental findings shed light on the conditions under which the inclusion of case reports increases versus decreases the policy relevance of news stories. Our findings also help explain previous inconsistencies in findings about the impact of case reports. Additional analyses allow us to speculate as to the reasons for the differential direction of effects.  相似文献

Abstract

Cognitive Analytic Therapy (CAT) is a collaborative time-limited psychotherapy developed by Ryle. The approach aims to formulate how early experiences influence the development of unhelpful patterns that maintain a person's current difficult experiences. Within the UK, forensic services personnel are increasing their uses of CAT approaches within contextual, i.e. treatment teams, settings. Offending behaviour is relational (perpetrator to victim), and CAT is a relational model. Within the context of National Health Service consultation service (Serious Offender Liaison Service) working with the Police and Criminal Justice Social Work to assess, formulate and give advice regarding working with serious sexual and violent offenders, often with personality disorders, a case example is presented. The paper suggests that utilising a relational model, such as CAT, and applying one of the main the tools of this approach, through diagrammatic representations (maps) of the formulation, can enable agencies working with an individual to share a common formulation and language.  相似文献

Candidates listed first on the ballot paper regularly receive more votes than other candidates, but what role does ballot layout play in this connection? Experimental studies from first-past-the-post systems show that the ballot position effect is causal as the order of names functions as a cue to voters. Does this also hold for PR systems where voters may vote for a party instead of a specific candidate? We identify a natural experiment in Danish local and regional elections involving more than 10,000 candidates on 103 different ballot papers using ballot layout to study ballot position effects. We find indeed, the ballot position/layout has a causal effect on election results in PR systems. Our findings indicate that the empirical domain of ballot position and layout effects is much wider than suggested by previous research.  相似文献

Generalized social trust has been argued to have positive effects for both individuals and society, but despite solid theoretical arguments in favour of different contextual effects, the empirical evidence remains scant. We here examine whether and how the effect of generalized trust on the propensity to become politically active is moderated by the level of generalized trust in society. We inspect two different causal mechanisms: The rainmaker effect, which entails that the effect of generalized trust is weaker at the individual level when there is a high level of generalized trust in society; and the sunmaker effect, which entails that the effect of generalized trust is strengthened by a high level of generalized trust in society. We examine the links for three forms of political participation: voting, institutionalized participation, and non-institutionalized participation. The data come from the fourth round of the European Social Survey from 2008 [European Social Survey. (2008 European Social Survey. (2008). Data file edition 4.0. Norwegian Social Science Data Services, Norway – Data Archive and distributor of ESS data. [Google Scholar]). Data file edition 4.0. Norwegian Social Science Data Services, Norway—Data Archive and distributor of ESS data], and we include 47,489 respondents in 25 democratic countries. The results from a series of multilevel logistic regressions suggest that the effect of generalized trust varies depending on the level of generalized trust in the surrounding community but the causal mechanisms differ for different kinds of political participation.  相似文献

Many studies show that policy makers react to the policy choices made in other jurisdictions, but we still know relatively little about the factors driving interdependent policy making, especially about how context shapes interdependence. Theoretical arguments suggest that contextual factors, such as stable institutions and geographic location, explain variation in interdependence. However, there is a lack of empirical research investigating contextual heterogeneity in interdependent policy making, mainly because it cannot be analysed with standard spatial econometric methods. This article introduces multilevel modeling that allows the study of contextual variation in interdependence and illustrates the method with the analysis of uneven tax competition in Switzerland. The findings of fine‐grained data show that cantonal governments compete more strongly with their competitors the closer a unit is located to a metropolis with comprehensive public good provision. The analysis demonstrates that we can better understand the mechanisms of interdependent policy making by studying its contextual drivers.  相似文献

Theories make varying predictions regarding the functional form of the relationship between neighborhood poverty and crime rates, ranging from a diminishing positive effect, to a linear positive effect, to an exponentially increasing or even threshold effect. Nonetheless, surprisingly little empirical evidence exists testing this functional form. This study estimates the functional form of the relationship between poverty and various types of serious crime in a sample of census tracts for 25 cities, and it finds that a diminishing positive effect most appropriately characterizes this relationship whether estimating the models nonparametrically or parametrically. Only for the crime of murder does some evidence exist of an accelerating effect, although this occurs in the range of 20 to 40 percent in poverty, with a leveling effect on crime beyond this point of very high poverty. Thus, no evidence is found here in support of the postulate of scholars extending William Julius Wilson's (1987) insight that neighborhoods with very high levels of poverty will experience an exponentially higher rate of crime compared with other neighborhoods.  相似文献

美国司法部与联邦贸易委员会于2010年8月联合发布了新版《横向合并指南》,新指南进一步淡化了结构主义色彩,打破了1992年指南所创设的五步分析法,相关市场界定的重要性也被大大降低,指南的制度设计趋向一个事实为基、更富弹性的分析框架。中国应借鉴美国的成熟经验,尽快研究制定横向合并指南,从"反竞争效果认定制度群"、"反竞争效果抗辩制度群"以及"反竞争效果补救制度群"三大方面来把握横向合并指南的内容。中国应注意平衡合并审查制度的确定性与灵活性,加强合并审查中法学与经济学的融合,并积极创建合并案件跟访制度。  相似文献

The global increase in extreme weather events in recent years has spurred political scientists to examine the potential political effects of such phenomena. This paper explores effect of flooding on electoral outcomes and offers evidence that the impact of adverse events varies with changes in political context. Using a difference-in-differences identification strategy to analyse three consecutive general elections in the United Kingdom (2015, 2017 and 2019), the paper finds variability in partisan electoral benefit from one election to the next that calls into question the blind retrospection and rally-round-the-leader explanations which are often advanced to account for electoral reactions to natural disasters. Instead, changing party positions on environmental issues appear to account more convincingly for shifts in electoral support in response to flooding. This suggests that parties can derive benefit from, or be punished for, the positions they take on environmental issues when extreme weather events affect citizens.  相似文献

This article touches upon theories accounting for the rise in adolescent anxiety and depression and how the prevalence of adolescent anxiety and depression affects how we navigate parenting plan evaluations. This article also discusses the importance of screening youth for depressive and anxious symptoms and assessing family, parental, and youth risk and protective factors related to adolescent depression and anxiety. This article also highlights the importance of assessing for mediating factors that increase the risk of anxiety and depression in youth in the context of parental separation, such as interparental conflict, financial difficulties, and limited contact with one parent. This article also identifies various methods of assessing depression and anxiety, including the adolescent interview, observations during the interview, and self-report measures. Additionally, this article discusses potential interventions that address mediators of the impact of divorce, such as parenting problems, family conflict, or the parent–child relationship.  相似文献
