Racial environment and political participation

This research addresses the determinants of mass participation by developing a model of how the racial environment influences mass participation in the United States. Prior literature on this research question presents two competing expectations. The power-threat hypothesis predicts that a larger size of different racial groups in local areas increases citizen participation because of more intensive interracial con- flicts, while the relational goods hypothesis predicts that a larger size of different racial groups decreases participation because of less frequent interaction with other in-group members. Both hypotheses, however, are derived from rather weak theoretical expectations, and neither is consistently supported in empirical analyses. This research offers a solution to this puzzle by arguing that economic and political characteristics of local areas determine how the racial composition influences mass participation. Local economic and political competition is expected to structure the nature of interracial and intraracial relations and therefore influence the utility calculation associated with political participation. I hypothesize that the power-threat effect on citizen participation is observed only when the degree of economic or political competition is high, while the relational goods effect is observed only when the degree of economic or political competition is low. Empirical analysis using Verba, Schlozman, and Brady’s Citizen Participation Study offers supportive evidence for my hypotheses. This research offers the first theoretically-motivated, rigorous analysis and evidence of the impact of immediate racial environment on individuals’ participation

Between credulity and scepticism: envisaging the fourth estate in 21st-century science journalism

For years Anglo-American news media participated in hyping claims of imminent cures from therapeutic cloning. This hype was scrutinized following the scientific fraud of South Korean therapeutic cloning researcher Hwang Woo-Suk. The scandal left questions about contemporary science journalists' commitment to the ideals of the press as fourth estate or watchdog. The present study adduces data from qualitative interviews with Anglo-American journalists (n = 18) who covered the issue of therapeutic cloning for major newspapers and periodicals. The journalists expressed commitment to the fourth estate ideal, although previous research has shown that their actual coverage fell short of this ideal. Synthesizing previous theory and research with the present study, four meso-level theoretical explanations are postulated for this disjuncture between ideals and practice in journalistic coverage of therapeutic cloning

Does political knowledge increase turnout? Evidence from the 1997 British general election

A number of recent formal models predict a positive effect of political knowledge on turnout. Both information acquisition and turnout, however, are likely to be determined by a similar set of variables, rendering hard the identification of a causal link in empirical investigations. Available empirical regularities should therefore be interpreted as mere correlations. I address this problem by using an intrumental variables approach, where the instruments are represented by various proxies of information supply on mass media. Using survey data from the 1997 British General Election Study, I show that political knowledge has a sizeable influence on the probability of voting and that mass media play an important role in influencing political participation.
