Presentation of the Italian version of the Obsessive Beliefs Questionnaire (part II).Convergent validity and specifity of the constructs in a clinical group
No full textThe Obsessive Beliefs Questionnaire (OBQ) is a questionnaire developed by the international group Obsessive Compulsive Cognitions Working Group (OCCWG) to assess cognitive domains that are considered central in the development and maintenance of obsessive-compulsive disorder. In the first part of this work we have described the Italian validation procedure and have presented some psychometric characteristics of the OBQ-46. In this second part we present the results related to concurrent and discriminant validity of the OBQ-46. The questionnaire was administered to 49 patients with obsessive-compulsive disorder, 21 patients with other anxiety disorders and to 50 non-clinical controls. Comparison between groups highlights the specificity of the responsibility for harm and for omission in OCD Italian population. In addition, the congruence between OC sub-types and beliefs does not seem entirely confirmed. Results are discussed in terms of future expansion and revision of centrality and specificity of the cognitive constructs related to obsessive-compulsive disorder and the possible existence of higher-order constructs

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
Observational learning of a discriminative shuttlebox avoidance by rats
No full text The study of observational learning of discriminative avoidance response in shuttlebox has methodological advantages over the usual appetitive responses. Three groups of 10 Wistar rats each received avoidance training after observation of a trained model, after observation of a naive model, after adaptation to procedure and no model. The first group performed better than the naive-model group both for frequency and latency of responses. The hypothesis that this learning occurs through observation of the model's behavior explains these results. However, observing the behavior to be learned does not facilitate acquisition of the avoidance response compared with rats learning after adaptation and no model. </jats:p
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
