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
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
Liberal and communitarian civic orientation in Poland as antagonistic concepts of the moral community. Do they imply different patterns of social and political commitment?
No full textLiberal and communitarian orientation refers to different concepts of the relationships linking citizens with the political community. A significant proportion of Poles combine their various elements, but both orientations are antagonistic in the prototype form. Earlier studies have shown that the distinction between liberalism vs. communitarianism was one of the critical dimensions of the Polish socio-political polarization. These two different concepts of the community imply two sets of hypotheses concerning their moral justifications and specific patterns of civic engagement. The hypotheses were verified in two survey studies conducted on large nationwide samples (N = 710 and N = 1477). Study 1 has shown that the hypothesized liberal orientation's embedding in individualizing moral values found empirical support only for the code of Liberty/Oppression. On the other hand, communitarian orientation turned out to be positively related not only to all components of binding moral values (Ingroup loyalty, Authority, Sanctity) but also to some individualizing moral values (Care, Fairness). Pattern of relationships with moral values largely explains the differences observed in study 2. In this study liberals are better at unconventional activity, which consists in exerting direct pressure on various groups of decision-makers. Communitarianism is more often expressed in helping and cooperation at the local or neighborhood community level. People with a liberal mindset want to be active when they perceive a threat to personal freedoms, human rights, tolerance, and socio-cultural diversity. Communitarians want to protect/cultivate traditional values and the welfare of the local and national community. For both orientations, competing values - liberal or communitarian - seem not even minimally worthy of public involvement
Discriminant analysis. Basic assumptions and applications in social research
No full textThis article is dedicated to the discriminant analysis - a statistical method that allows to test differences between groups of observations (two or more) based on a set of selected independent variables (predictors). It may be effectively applied to various fields of social sciences and practice (psychology, sociology, political science, economy, law). Linear combination of independent variables obtained on the basis of the discriminant analysis model serves as a criterion of assigning observations to groups. Information carried by independent variables is saved in a synthetic form as discriminant function scores. Discriminant analysis may have two goals: discrimination (separation) and classification (allocation). In the first case, the researcher tries to explain causes of differences between groups of observations by making use of their characteristics available as 'disciriminating᾿ variables. In the second case, the researcher seeks to find a mathematical equation that combines group characteristics of observations in order to effectively predict the unknown group category to which the observation belongs. The article consists of two parts. The first part contains a general description of the statistical model, the second includes two empirical examples of its application - for two and for four groups of observations.peerReviewedpublishedVersio
