Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
A possible correlation between diet, serum oxytetracycline concentration, and onset of reproductive disturbances in bitches: Clinical observations and preliminary results
Based on the increase of food-related disturbances in animals and the recent findings concerning the toxicity of oxytetracycline (OTC) presence within pet food, we compared the effectiveness of two commercially available diets in 36 bitches suffering from reproductive disturbances. We ran a randomized clinical evaluation over a 90-day period. Bitches were randomly assigned to receive a control diet (CD) or a nutraceutical diet (ND) and were assessed for the presence of OTC in their sera before and at the end of the study. Sixteen of 18 bitches in the ND group went into heat within an average of 35.5 ± 3.1 days, and 15 of them became pregnant. In the CD group, 12 of 18 bitches went into heat within an average of 54.1 ± 3.2 days, and 10 of them became pregnant. A significant decrease in mean OTC serum concentration was observed in bitches belonging to the CD and ND group (P < 0.01). The overall amelioration, in particular in the ND group, provides new insights for future studies involving the modification of diet in order to restore the normal physiology of bitches suffering from reproductive disturbances
Variations on the Author
“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
We 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
