20.500.12556/DKUM-66398 Homophily in coauthorship networks of East European sociologists We study to what degree and how homophily and network properties affect individual citation counts of researchers in the sociology departments of three East European countries, namely Poland, Romania, and Slovenia. We built first-order personal coauthorship networks out of the Web of Science publication records. Each sociologist is assigned as a focal node or ego, while her coauthors are alters. We analyze the data using structural measurements methods, hierarchical regression models, and we make visualizations based on the clustered graph technique. For all three populations, our results indicate that the mean score of the citations of alters substantially predicts the citation counts of egos. In particular, citation similarity increases the chances for coauthorship ties. Evidence for the impact of network properties on the citation levels of egos is mixed. For Poland, normalized ego-betweenness shows a negative effect on citation counts, while network density displays a positive one. For Romania and Slovenia, network characteristics have only a minor impact. Even if the visual summarization of the personal networks uncovers a wide palette of coauthorship patterns, homophily appears to be pervasive. These results are relevant for domestic policy makers who aim to improve the aggregated research performance in East European countries. social network sociology homophily physics of social systems družbena omrežja sociologija homofilija fizika socioloških sistemov true true true Angleški jezik Slovenski jezik Članek v reviji 2017-06-23 11:05:36 2017-06-23 11:07:40 2024-09-02 13:58:28 2019-07-11 15:46:08 2016 0 0 str. 1-12 Letn. 6 2016 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2016-08-26 2016-10-11 2016-10-27 2045-2322 316.472.4 18727432 22738696 10.1038/srep36152 2045-2322 URN:SI:UM:DK:2OCQ62YD Scientific_Reports_2016_Hâncean,_Perc_Homophily_in_coauthorship_networks_of_East_European_sociologists.pdf Scientific_Reports_2016_Hâncean,_Perc_Homophily_in_coauthorship_networks_of_East_European_sociologists.pdf 1 89C48E4A878E1D50825AB1FF0179E745 52960ccce413a01fe4bc23eee3a39d44fad917b4507532a1c7a1eacc781182dc 4a30f02b-7c0e-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=113015 http://www.nature.com/articles/srep36152 1 https://dk.um.si/Dokument.php?lang=slv&id=113014 Fakulteta za naravoslovje in matematiko 0 0 0
