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
Health-related quality of life among first-degree relatives of patients with obsessive-compulsive disorder in Italy
No full textOBJECTIVE: The aim of this study was, first, to examine health-related quality of life among relatives of Italian patients with obsessive-compulsive disorder and, second, to search for potential predictors of quality of life among these relatives. METHODS: Health-related quality of life was assessed among 64 non-psychiatrically ill family members of 48 patients with obsessive-compulsive disorder by using the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). The Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) and the Structured Clinical Interview for DSM-IV Axis II Disorders were used to assess obsessive-compulsive disorder among the patients. Mean SF-36 scores of participants were compared with expected scores for 2,031 persons from the Italian general population (Italian norms) by using the one-sample t test. Correlates of health-related quality of life were examined by means of independent-sample t tests and Pearson correlations; variables significantly associated with SF-36 subscales were entered into a stepwise multiple linear regression analysis with the physical and mental components as dependent variables. RESULTS: Relatives of patients with obsessive-compulsive disorder showed a greater impairment in health-related quality of life in the SF-36 subscales of role limitations due to physical health, vitality, social functioning, role limitations due to emotional problems, and mental health. When a stepwise multiple linear regression analysis was performed with the physical component and the mental component of the SF-36 as dependent variables, female gender, older age, and the total score on the Family Accommodation Scale predicted a poorer score on the physical component, whereas the only predictor of a poorer score on the mental component was the patient's Y-BOCS total score. CONCLUSIONS: The study provides evidence that obsessive-compulsive disorder impairs health-related quality of life among family members of patients with obsessive-compulsive disorder, even among healthy family members. Involving family members in the treatment of obsessive-compulsive disorder could improve their perceived quality of life
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
