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
Il corpo nella mente: ruolo della pratica sportiva nell'auto descrizione del proprio fisico in adolescenti e giovani con disabilità motoria
No full textDoes perceived sport competence influence physical activity enjoyment?
Full text linkIn the sport and physical activity (PA) field, enjoyment is a positive affective response to the sport experience (Scanlan & Simons, 1992) and it can also be considered an important factor in promoting active lifestyles and regular PA among school-aged children (Carraro et al., 2008). The aim of thepresent study was to investigate the effects of perceived sport competence on PA enjoyment.
Methods
Partecipants were 394 pupils (173 boys and 221 girls) aged between 12 and 13 years (M=12.2). The Physical Self-Description Questionnaire-Short (PSDQ-S;
Marsh et al., 1994) and the Physical Activity Enjoyment Scale (PACES; Carraro
et al., 2008) were completed. Pearson’s correlation test was used to measure
the association between variables.
Multiple linear regression analysis was conducted to investigate the correlation between PSDQ-S scores (independent variables) and PACES total score (dependent variable).
Results
Pearson’s correlation test revealed the following positive associations
between PSDQ-S variables and PACES total score: endurance (r = .527, p < .001);
flexibility (r = .206, p < .001); strength (r = .365, p < .001); coordination(r = .427, p < .001); sport skill (r = .546, p < .001). Multiple linear regression analysis showed the following score indices: SE = 7.76; t = 20.79; R2 = .363; F(5, 388) = 44.13; p < .001.
Our results highlighted positive associations between physical self-concept scales and PA enjoyment, and our hypothesis that perceived sport competence can be considered a good predictor of PA enjoyment was confirmed. The results could contribute to our understanding of the processes involved in the promotion of active lifestyles and regular PA among young people
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
