Resilience and Vulnerability in Adolescents: Genetic Influences on Differential Response to Risk for Delinquency

Prior research has identified a vast number of correlates for delinquent behavior during adolescence, yet a considerable number of errors in prediction remain. These errors suggest that behavioral development among a portion of youths is not well understood, with some exhibiting resilience and others a heightened vulnerability to risks. Examining cases that do not confirm prediction outcomes provides an opportunity to achieve a greater understanding of the relationships between risk factors and delinquency, which can be used to improve theoretical explanations of behavior. This study explores the contribution of genetic and environmental factors to differences in individual responses to cumulative risk for delinquency among a sample of adolescent twins (N = 784 pairs, 49 % female) in the National Longitudinal Study of Adolescent Health. The results indicate that additive genetic and unique environmental factors significantly contribute to variation in responses to cumulative risk across 14 risk factors spanning individual, familial, and environmental domains. When analyzed separately, the majority of the difference between vulnerable youths and the overall population was attributed to genetic influences, while differences between resilient youths and the population were primarily attributed to environmental influences. The findings illustrate the importance of examining both genetic and environmental influences in order to enhance explanations of adolescent offending.     

Foreign threat and political party change: Russia and changes in party manifestos

How do political parties react to foreign security threats? There has been very little attention paid in the literature generally to how parties react to international events, particularly how parties react to foreign policy threats. Using data from the Comparative Manifesto Project, we examine how political parties in countries in Europe have reacted to Russian actions in terms of their emphasis on security issues. Based upon our analysis of the manifestoes from 331 parties in 36 countries we find that, generally, interstate threats have no significant effect on the military position adopted by political parties, although these effects vary by party type and by the type of threat. Russian based threats appear to be associated with the Far Left becoming more dovish (which is consistent with what would be expected by the literature) and the Far Right becoming significantly less hawkish.     

The ideological nationalization of partisan subconstituencies in the American States

Since the mid-twentieth century, elite political behavior in the United States has become much more nationalized. In Congress, for example, within-party geographic cleavages have declined, roll-call voting has become more one-dimensional, and Democrats and Republicans have diverged along this main dimension of national partisan conflict. The existing literature finds that citizens have only weakly and belatedly mimicked elite trends. We show, however, that a different picture emerges if we focus not on individual citizens, but on the aggregate characteristics of geographic constituencies. Using biennial estimates of the economic, racial, and social policy liberalism of the average Democrat and Republican in each state over the past six decades, we demonstrate a surprisingly close correspondence between mass and elite trends. Specifically, we find that: (1) ideological divergence between Democrats and Republicans has widened dramatically within each domain, just as it has in Congress; (2) ideological variation across senators’ partisan subconstituencies is now explained almost completely by party rather than state, closely tracking trends in the Senate; and (3) economic, racial, and social liberalism have become highly correlated across partisan subconstituencies, just as they have across members of Congress. Overall, our findings contradict the reigning consensus that polarization in Congress has proceeded much more rapidly and extensively than polarization in the mass public.

Inequality,democracy and taxation: Lessons from the post-communist transition

Using data for the period 1989 – 2002, we examine the determinants of income inequality in post-communist economies. We find a strong positive association between equality and tax collection but note that this relationship is significantly stronger under authoritarian regimes than under democracies. We also discover that countries introducing sustainable democratic institutions early are characterised by lower inequality. We also confirm that education fosters equality and find that larger countries are prone to higher levels of inequality.
