Author ranking evaluation at scale     

Marcel Dunaiski  Jaco Geldenhuys  Willem Visser 《Journal of Informetrics》2018,12(3):679-702

We evaluate author impact indicators and ranking algorithms on two publication databases using large test data sets of well-established researchers. The test data consists of (1) ACM fellowship and (2) various life-time achievement awards. We also evaluate different approaches of dividing credit of papers among co-authors and analyse the impact of self-citations. Furthermore, we evaluate different graph normalisation approaches for when PageRank is computed on author citation graphs.We find that PageRank outperforms citation counts in identifying well-established researchers. This holds true when PageRank is computed on author citation graphs but also when PageRank is computed on paper graphs and paper scores are divided among co-authors. In general, the best results are obtained when co-authors receive an equal share of a paper's score, independent of which impact indicator is used to compute paper scores. The results also show that removing author self-citations improves the results of most ranking metrics. Lastly, we find that it is more important to personalise the PageRank algorithm appropriately on the paper level than deciding whether to include or exclude self-citations. However, on the author level, we find that author graph normalisation is more important than personalisation.  相似文献   

Peer victimization,deviant peer affiliation and impulsivity: Predicting adolescent problem behaviors     

《Child abuse & neglect》2016

Abundant evidence has demonstrated an association between peer victimization and adolescent problem behaviors. However, there is a large gap in knowledge about the potential mediators that associate peer victimization with problem behaviors and the potential moderators that exacerbate or buffer this association. The current study examined whether deviant peer affiliation mediated the association between peer victimization and problem behaviors and whether the direct and indirect associations were moderated by impulsivity. A sample of 1401 adolescents (50.1% boys, 11–14 years old) completed anonymous questionnaires regarding peer victimization, impulsivity, deviant peer affiliation, and problem behaviors. Gender, age and socioeconomic status (SES) were controlled for in the analyses. Structural equation models showed that peer victimization was significantly associated with more problem behaviors, and this association was mediated by deviant peer affiliation. Impulsivity moderated both the direct association (peer victimization → problem behaviors) and the second stage of the indirect path (deviant peer affiliation → problem behaviors). Specifically, these associations were especially stronger for adolescents with higher impulsivity. Identifying the processes by which peer victimization is associated with adolescent problem behaviors has important implications for an integrative framework of theory and prevention.  相似文献

德莱塞长篇小说中真实作者宗教意识产生原因浅析     

杨芳 《十堰职业技术学院学报》2011,24(3):84-88

一直以来,在学术界对德莱塞都有着这样一个较为普遍的认知:德莱塞,一位伟大的美国自然主义作家。由于作品中强烈的自然主义风格及作者本人对外宣称不信仰宗教,使得学界对于德莱塞的研究很少注意到其作品中的宗教意识。而我们细读德莱塞的每一部长篇小说就会感觉到,他的小说中或多或少地都渗透着宗教的情结。所以本文试图以叙事学这种在国内还较为新兴的、强势的研究方法为切入点来探讨德莱塞长篇小说中的宗教意识产生原因。  相似文献
