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
Psychoeducatlon in binge eating disorder: Factors predicting efficacy
No full textObjective: The aim of this study is to identify the factors that influence the effectiveness of group psychoeducation, defined as absence of binge eating, at the end and one year after therapy, in subjects with binge eating disorder (BED). Also was evaluated the correlation between binge eating and obesity, assessing which factors may be predictors for satisfyingly weight loss. Methods: A total of 26 patients were included in the study (Table I). Subjects who continued binge eating at the end of the therapy (t1) were defined as non-responsive patients (NR); those who continued binge eating one year after therapy (t2) were defined as non-abstinent patients (NA) (Fig. 1). The predictor factors were divided into clinical and psychometric variables. The following clinical data were considered: years of dieting and binge eating, body mass index (BMI) and the frequency of binge eating at the beginning of therapy (t0). The psychometric data analysed were: eating aptitude and behaviour (EDI-2), alexithymia (TAS-20), family support (FA), anxiety and depression (HADS). These data were estimated at t0 and t1. Results: The NR (n = 6; 23.1%) were attributed higher scores in the anxiety subclassification (HADS) at t0. The NA (n = 7; 26.9%) presented a higher rate and a higher number of years of binge eating, furthermore they had a lower level of family support at t0. No patients had a satisfactory weight loss at t1; 19.2% of the patients lost weight at t2 (Table II). Conclusions: The present study confirms, as observed in other studies, that clinical parameters, like the rate and number of years of binge eating at the beginning of therapy, are predictor factors for maintenance of effectiveness one year after treatment. Furthermore, anxiety before therapy results in a lower response to treatment and poor family support is associated with inadequate results of maintenance one year after therapy. No association between weight loss and disappearance of binge eating was observed. Thus, these parameters may be used by the clinician to identify a population of patients who need another therapeutic approach, with integrated and long interventions
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
