ABSTRACT

This article analyses how the presence of a dominant group of voters within the electorate affects voter turnout. Theoretically, we argue that its absolute size affects turnout via increased free-riding incentives and reduced social pressure to vote within a larger dominant group. Its relative size compared to other groups within the electorate influences turnout through instrumental and expressive responses – in both the dominant and dominated groups – to the degree of electoral competition between groups. Empirical evidence from a large cross section of German municipalities is in line with these theoretical predictions. The observed effects should be taken into account when redesigning electoral jurisdictions through, for instance, municipal mergers or gerrymandering.  相似文献

Given that minority ethno-political organizations are generally weaker than states yet seek to change their policies or remove the ruling regime from power, why would negotiation occur? States prefer to ignore or repress such organizations, which typically have little to offer in return amidst negotiations that can legitimize them while delegitimizing the state. When a challenging organization establishes governing structures and controls movement in part of a state's territory, however, it can easily inflict significant economic and political costs on the state while also possessing a valuable asset to exchange for concessions. An organization with territorial control cannot be ignored, while the state will have a strong incentive to negotiate before the state loses more face, the group gains more legitimacy, neighboring states are more likely to invade, and the international community is more likely to formally recognize any facts on the ground as a new status quo. Our analysis of 118 organizations in the Middle East and North Africa from 1980–2004 reveals that territorial control is the most important determinant of intrastate negotiation. In regards to existing scholarship, this suggests that a certain type of successful violence works—not all violence and not only nonviolence—while certain types of strong organizations—those that control territory—are more likely to reach negotiations with the state than weak ones.  相似文献

The main aim of this study was to investigate the causal nature of the relationship between adolescents’ risky sexual behavior on the internet and their perceptions of this behavior. Engagement in the following online behaviors was assessed: searching online for someone to talk about sex, searching online for someone to have sex, sending intimate photos or videos to someone online, and sending one’s telephone number and address to someone exclusively known online. The relationship between these behaviors and adolescents’ perceptions of peer involvement, personal invulnerability, and risks and benefits was investigated. A two-wave longitudinal study among a representative sample of 1,445 Dutch adolescents aged 12–17 was conducted (49% females). Autoregressive cross-lagged structural equation models revealed that perceived peer involvement, perceived vulnerability, and perceived risks were all significant predictors of risky sexual online behavior 6 months later. No reverse causal paths were found. When the relationships between perceptions and risky sexual online behavior were modeled simultaneously, only perceived peer involvement was a determinant of risky sexual online behavior. Findings highlight the importance of addressing peer involvement in future interventions to reduce adolescents’ risky sexual online behavior.  相似文献

Few studies have examined risk factors of childhood and early adolescent depressive symptomatology trajectories. This study examined self-report depressive symptomatology across a 6-year time period from 2nd to 8th grade to identify latent groups of individuals with similar patterns of depressive phenomena in a sample of 951 children (440 girls, 511 boys). Analyses, using semiparametric group modeling (SGM), identified 5 trajectory groups for girls and boys: low depressed stables, low depressed risers, mildly depressed stables, moderately depressed changers, and moderately depressed risers. Individual risk factors, with the exception of shy/withdrawn behavior, were significantly different across trajectory group membership for boys and girls, as was low-income status for boys. Boys in the low depressed and mildly depressed stable trajectory groups had significantly higher levels of antisocial behavior, attention problems, and lower social competency compared to girls in similar groups. These results suggest that universal prevention programs implemented in early elementary school that target selected risk factors may be helpful in reducing future adolescent mental health problems, specifically depressive symptomatology.  相似文献

Much economic policy is deliberately shifted away from direct political processes to administrative processes—political pressure deflection. Pressure deflection poses a puzzle to standard political economy models which suggest that having policies to ‘sell’ is valuable to politicians. The puzzle is solved here by showing that incumbents will favor pressure deflection since it can deter viability of a challenger, essentially like entry deterrence. U.S. trade policy since 1934 provides a prime example, especially antidumping law and its evolution.  相似文献

According to the democratic domino theory, increases or decreases in democracy in one country spread and "infect" neighboring countries, increasing or decreasing their democracy in turn. Using spatial econometrics and panel data that cover over 130 countries between 1850 and 2000, this article empirically investigates the democratic domino theory. We find that democratic dominoes do in fact fall as the theory contends. However, these dominoes fall significantly "lighter" than the importance of this model suggests. Countries "catch" only about 11% of the increases or decreases in their average geographic neighbors' increases or decreases in democracy. This finding has potentially important foreign policy implications. The "lightness" with which democratic dominoes fall suggests that even if foreign military intervention aimed at promoting democracy in undemocratic countries succeeds in democratizing these nations, intervention is likely to have only a small effect on democracy in their broader regions.  相似文献

This article represents the effect of public opinion on government attention in the form of an error-correction model where public opinion and policymaking attention coexist in a long-run equilibrium state that is subject to short-run corrections. The coexistence of policy-opinion responsiveness and punctuations in political attention is attributed to differences in theoretical conceptions of negative and positive feedback, differences in the use of time series and distributional methods, and differences in empirical responsiveness of government to public attention relative to responsiveness to public preferences. This analysis considers time-series data for the United Kingdom over the period between 1960 and 2001 on the content of the executive and legislative agenda presented at the start of each parliamentary session in the Queen's Speech coded according to the policy content framework of the U.S. Policy Agendas Project and a reconstituted public opinion dataset on Gallup's "most important problem" question. The results show short-run responsiveness of government attention to public opinion for macroeconomics, health, and labor and employment topics and long-run responsiveness for macroeconomics, health, labor and employment, education, law and order, housing, and defense .  相似文献
