Anti-school attitudes, school culture and friendship networks
We estimate the influence of classmates’ ability characteristics on student achievement in exogenously formed university student groups. The study uses administrative data on undergraduate students at a large selective university in Russia. The presence of high-ability classmates has a significant positive effect on individual grades in key economics and mathematics courses as well as on overall academic performance. While a simple linear-in-means model reveals moderate peer effects, non-linear specifications give strong evidence that students at the top of the ability distribution derive the greatest benefit from high-ability classmates. Less able students are not affected by peers and have no significant influence on peers’ outcomes.
A number of researchers have studied the effect of social networks on student academic performance, but the results are not only contradictory but also limited by the use of self-reported estimations of social network use. This paper overcomes this problem, however, as we collect unique data on the real time spent by Russian students in the Vk.com social network. Our results suggest that time spent on the social network before an exam can significantly improve student performance on the exam. The time spent online, however, influences exam results indirectly via peer effects rather than directly. Accordingly, social networks cannot only bring joy, but they can also be a productive channel for exploiting peer effects if the students are connecting with bright and talented classmates.
We estimate the influence of classmates ability characteristics on student achievement in exogenously formed student groups. The study uses the administrative data on undergraduate students in large selective university in Russia. The presence of high-ability classmates has positive effect on individual academic performance, and most benefit is gained by students at the top of the ability distribution. The increase in share of less able students influences individual grades insignificantly.
Adult mortality has been lower in Kyrgyzstan vs. Russia among males since at least 1981 and among females since 1999. Also, Kyrgyzstan’s mortality fluctuations have had smaller amplitude. This has occurred in spite of worse macro-economic outcomes in Kyrgyzstan. To understand these surprising patterns, we analyzed cause-specific mortality in Kyrgyzstan vs. Russia for the period 1981-2010, using unpublished official data. We find that, as in Russia, fluctuations in Kyrgyzstan have been primarily due to changes in external causes and circulatory causes, and alcohol appears to play an important role. However, in contrast with Russia, mortality from these causes in Kyrgyzstan has been lower and has increased by a smaller amount. As a result, the mortality gap between the two countries is overwhelmingly attributable to external and cardio-vascular causes, and more generally, to causes that have been shown to be strongly related to alcohol consumption. These cause-specific results, together with the existence of large ethnic differentials in mortality in Kyrgyzstan, highlight the importance of cultural and religious differences, and their impact on patterns of alcohol consumption, in explaining the mortality gap between the two countries. These findings show that explanatory frameworks relying solely on macro-economic factors are not sufficient for understanding differences in mortality levels and trends among former Soviet republics.
This article addresses the questions, What do children in urban areas do on Saturdays? What type of organizational resources do they have access to? Does this vary by social class? Using diary data on children’s activities on Saturdays in the Phoenix-Mesa-Scottsdale metropolitan area, the authors describe the different types of venues (households, businesses, public space, associations, charities, congregations, and government/tribal agencies) that served different types of children. They find that the likelihood of using a charity or business rather than a government or tribal provider increased with family income. Also, the likelihood of using a congregation or a government facility rather than business, charity, or household increased with being Hispanic. The authors discuss implications for the urban division of labor on Saturdays and offer research questions that need further investigation.
This article is talking about state management and cultural policy, their nature and content in term of the new tendency - development of postindustrial society. It mentioned here, that at the moment cultural policy is the base of regional political activity and that regions can get strong competitive advantage if they are able to implement cultural policy successfully. All these trends can produce elements of new economic development.
