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
The role of personality for gender gaps in political interest and activity
No full textWomen have been found to be, on average, less interested in politics and less politically active than men, which might reduce the representation of women's interests in a democracy. In order to enhance the understanding of these gender gaps, this preregistered study analyzes the role of personality differences for gender gaps in political interest and activity. I use a large representative sample of the adult population in Germany for the analysis. First, I replicate the findings that women tend to have lower scores in political interest and activity and that these gaps are not fully explained by demographic, situational, and structural factors. Second, I find that the remaining gender gaps in political interest and activity are, overall, not significantly explained by gender differences in personality. However, gender differences in some specific personality traits partially explain the political gender gaps: Women's higher average agreeableness contributes to the gender gap in political interest, and women's higher average conscientiousness contributes to the gender gap in political activity
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
Ethnic Minority Background and Personality Characteristics: Evidence from a Representative Sample of the Adult Population
No full textI measure statistical differences in personality characteristics (personality traits, attitudes, and values) between individuals with an ethnic minority vs. ethnic majority background. This analysis might inform research on explanations of discrimination, as some researchers have proposed that discrimination might be based on statistical group differences in unobserved characteristics, such as personality characteristics (statistical discrimination). I use data of N = 6,330 individuals from a representative sample of the adult population in Germany. Analogously to field experiments showing ethnic discrimination, only individuals who have completed secondary schooling in Germany are considered in the analyses. The results suggest that, on average, ethnic minority individuals score slightly higher in openness and slightly lower in conscientiousness than ethnic majority individuals. These statistical differences are more robust—but still small—when demographic factors and measures of the qualification level are held constant. I find no significant ethnic differences in the other Big Five personality traits, feeling of connectedness to the majority population, or gender equality values. Overall, the results provide only weak support for the theory of statistical discrimination as a potential explanation of ethnic discrimination.This Version: January 202
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
Does money change who you are? Quasi-experimental evidence on the effects of wage increases on personality
No full textUsing the 2015 introduction of a statutory minimum wage in Germany as a quasi-experiment, I investigate the effects of wage increases on personality. The degree to which each worker's wage is intended to be affected by the reform is used as an instrument for the relative increase in the worker's hourly wage in a two-stage least squares estimation based on nationally representative panel data (N = 1,955 individuals). The results show no significant effects of relative wage increases on personality traits. As the confidence intervals indicate, any substantial effects of wage increases on personality are largely rejected by the results
Is There an Ethnic Pay Gap in Germany? Evidence from a Representative Sample of the Adult Population
No full textThis study investigates a disparity in hourly wages (i.e., a pay gap) between employees with an ethnic minority vs. ethnic majority background in Germany. To this aim, a Blinder-Oaxaca decomposition based on a representative survey of the adult population in Germany is used. The analysis is restricted to employees who completed secondary schooling in Germany (N = 9,304). The results show that, overall, ethnic minority employees receive significantly lower gross hourly wages than ethnic majority employees, and this difference amounts to 13.8%. The larger part of this gap is explained by group differences in demographic, human capital, and occupational characteristics—in particular, education level, work experience, job tenure, the precise employment status, and occupational status. However, there is also a significant unexplained pay gap that amounts to 2.7% lower wages for ethnic minority (vs. ethnic majority) employees, indicating potential wage discrimination against ethnic minority employees. The total, explained, and unexplained ethnic pay gaps appear to be somewhat larger among men than among women. Finally, an exploratory analysis suggests that the part of the ethnic pay gap that has remained unexplained might be largely explained by whether employees hold the German citizenship and whether they were born in Germany
