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
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
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
Mothers and the Process of Social Stratification. De invloed van de moeder op het proces van statusverwerving.
Full text linkThe present study embeds the mother's influence into the classical model of status attainment (Blau & Duncan 1967, The American Occupational Structure) that originally was designed to point out status relations between fathers and sons. This model has layed down important methodological foundations upon which much of today's research on social stratification is based. Still most of the research carried out deals only with the relation between the father's and his son's or daughter's socio-economic position. Therefore, the question in how far the mother's and her son's or daughter's socio-economic positions are related, is subject to the current investigation. How large is her influence on her son's and daughter's status attainment? How does her influence, in comparison to that of the father, affect a child's status attainment? In how far does the mother's status background have a special impact on her daughter's, compared with her son's status attainment? And last but not least, how has the mother's influence on the structure of social stratification, compared to the father's influence, changed over time? My conclusions are based on the empirical results drawn from several sources of data: U.S. American (NSFH), German (West German Life History), and Dutch (Households in the Netherlands 1995, Netherlands Family Survey 1992-93) representative household surveys.
The first general conclusion is that the mother's socio-economic resources always have been and up to this day remain to be an important source for the transfer of status advantages from one generation to the next. Her influence on her children's educational attainment is as large as the father's influence. However, observed through a period of 40 years we notice a steady decrease of the influence of both parents on children's educational levels. As parents' influence declines, slowly some differences evolve regarding the relative weights of parents' socio-economic resources for the determination of children's levels of schooling. To an increasing degree parents' (mean) educational level is becoming the important predicament to prognosticate their offspring's educational level. Hence, the education of children is becoming less restricted by the fact that parents have good jobs and can afford to pay for their children's schooling, but increasingly delimited by their parents' (mean) educational level.
Regarding occupational reproduction, the mother's job status influences only her daughter's and not her son's occupational attainment. What is more, her influence increases as the career of the daughter advances. As the daughter's career continues her job status becomes increasingly similar to that of her mother. The dynamic perspective of occupational status reproduction thus reveals the existence of an occupational sex-role model between mothers and daughters. Furthermore, part of my analysis showed that the importance of the mother's occupational status for the daughter's occupational attainment increases for birth cohorts born between 1965 and 1975. In general, studies that find a decreasing influence of social origin on occupational reproduction are based on older data. According to these current results we may be witnessing a reversal of trends found for women's occupational status reproduction in recent years.
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
