Educational attainment in adolescence is of paramount importance for attaining higher education and for shaping subsequent life chances. Sociological accounts focus on the role of differences in socioeconomic resources in intergenerational reproduction of educational inequalities. These often disregard the intergenerational transmission of cognitive ability and the importance of children’s cognitive ability to educational attainment. Psychological perspectives stress the importance of cognitive ability for educational attainment but underemphasize potentially different roles of specific socioeconomic resources in shaping educational outcomes, as well as individual differences in cognitive ability. By integrating two strands of research, a clearer picture of the pathways linking the family of origin, cognitive ability, and early educational outcomes can be reached. Using the population-based TwinLife study in Germany, we investigated multidimensional pathways linking parental socioeconomic position to their children’s cognitive ability and academic track attendance in the secondary school. The sample included twins (N?=?4008), respectively ages 11 and 17, and siblings (N?=?801). We observed strong genetic influences on cognitive ability, whereas shared environmental influences were much more important for academic tracking. In multilevel analyses, separate dimensions of socioeconomic resources influenced child cognitive ability, controlling parental cognitive ability. Controlling adolescent cognitive ability and parental cognitive ability, parental socioeconomic resources also directly affected track attendance. This indicated that it is crucial to investigate the intertwined influences on educational outcomes in adolescence of both cognitive ability and the characteristics of the family of origin. 相似文献

AbstractExisting research on party behaviour has largely focused on the drivers of issue salience in direct party communication. However, less is known about party?issue linkages in election campaigns covered by the mass media, from which most voters get their information about party positions. Against this background, this article explores how two important drivers of issue salience in direct party communication – issue ownership and systemic salience – play out in the media. Based on considerations about the news value of specific party?issue associations, one would expect both relationships to be particularly important in the media. Despite substantial similarities in party?issue linkages across platforms, a comparison of manifestos and newspaper content reveals evidence for this claim. In particular, smaller parties are hardly covered in the news on issues they do not own, while large parties are especially covered on salient topics. These findings contribute to our understanding of issue competition in mediated environments. 相似文献

We develop a new conceptualization of political advertising effects by looking at the effect of the marginal advertising dollar during the heat of presidential campaigns. We argue that in contrast to other studies investigating effects of political ads, our approach is more apt to capture the natural environment in which political ads are encountered during a presidential campaign. We focus on the intense inundation of political ads voters are confronted with in swing states in the weeks leading up to the presidential election, and argue that it is unclear a priori whether we should expect advertising to affect vote intention in that critical circumstance. We empirically validate this hypothesis using a trove of data from the 2012 campaign: daily polling in media markets around the country, detailed data on all registered voters in the country, all TV advertisements by market and exact airtime, and the entire Twitter corpus. We find that neither overall increases in advertising spending nor partisan imbalances in spending expanded the candidates’ electorate. In fact, total Designated Market Area (DMA)-level spending significantly moderates a negative relationship between spending advantages and advantages in vote intention, suggesting a boomerang effect of additional spending late in the campaign. In closing, we discuss the ramifications of our findings for future research, and stress the importance of research tracking advertising effects. 相似文献

This study traces the (geopolitical) knowledge on terrorism circulating in Germany, India, Kenya, and the United States based on an analysis of school textbooks. It contributes to the existing literature in three ways. First, it transcends the Western-centrism of International Relations by analysing discourses from the Global North and the Global South. Second, it introduces school textbooks as a crucial object of research in constructivist terrorism studies and International Relations. School textbooks indicate the (geopolitical) knowledge deemed essential in a given society, but are also widely distributed among young people. Third, I address the debate about a presumed homogenization and internationalization of terrorism discourses in recent years. Results show that all four discourses depict terrorists as evil, focus on external non-state groups as perpetrators and associate terrorism with Islam. But there are also considerable differences regarding the relative importance of terrorism as a security threat, the referent object affected and the countermeasures deemed appropriate. 相似文献
