Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Waarom hoger opgeleiden zich tegen het politieke systeem keren: Een onderzoek naar de motieven van hoger opgeleiden om te stemmen op populistisch radicaal rechtse partijen
Full text linkThe majority of the voting electorate of Populist Radical Right Parties (PRRPs) generally consists of lower educated citizens. However, Forum for Demo- cracy and JA21 have succeeded in attracting higher educated voters to their electorate. Little scientific research has been performed on the motives of higher educated citizens to vote for these parties, as traditional explanations often focus on the lower educated. The focus of this inquiry will, therefore, be on understanding the deliberations of higher educated citizens and how these have incentivised them to vote for Populist Radical Right Parties. 12 semi-structured interviews were held with higher educated PRRP voters. The results show that cultural factors and political distrust were most relevant in higher educated citizens’ choice to vote for these parties. Especially po- litical distrust seems important, which is shaped by the perceived political knowledge and sophistication of the higher educated. This research shows that the underlying motives of the higher educated to vote for these parties may differ from existing explanations that focus on lower educated voters
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Assessing the impact of school-based interventions using synthetic control methods
No full text<p>Evaluating policy programs in the educational field can be challenging due to the complex structure of the educational landscape. In this project, we leverage the rich CBS microdata to estimate the effectiveness of an extended school week intervention in Rotterdam South. The intervention is one of the main pillars of the National Program Rotterdam South (NPRZ) and aims to improve test scores and primary school advice in approximately 30 primary schools. To estimate the impact of the intervention, we use synthetic control methods, which allow us to not only estimate the average causal effect of the intervention, but also to investigate the variability of the intervention among schools. We discuss the application of synthetic control methods in the educational field and possible advantages and drawbacks. Finally, we consider the implications of the results for the extended school week intervention.</p>
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
