Effects of fluoxetine on aggressive behavior of adult inpatients with mental retardation and epilepsy
No full textNineteen mentally retarded inpatients with epilepsy and a history of current or recent aggressive behavior were treated with 20 mg of fluoxetine daily. All were concurrently taking other psychotropic medications, including carbamazepine and neuroleptics. A standardized rating scale (MOAS) was used to assess the effects of fluoxetine on aggressive behavior. There were wide individual differences in drug response. In nine patients, fluoxetine treatment was associated with increased aggression, while drug withdrawal led to a decrease to below pretreatment levels. Two hypotheses concerning the apparent association between fluoxetine and increased aggression are discussed: 1) adverse effects secondary to either drug interaction or fluoxetine overmedication; and 2) a specific serotonergically mediated effect on the regulation of aggression. This study suggests that the clinician who treats mentally retarded patients with impulsive aggressive behavior should remain aware that fluoxetine may have diverse effects on aggression that vary over time and interindividually
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
XR-Based Mindfulness and Art Therapy: Facing the Psychological Impact of Covid-19 Emergency
No full textThe latest events related to the spread of the Covid-19 virus have seen the rise of new social needs in countries like Italy, especially regarding the most vulnerable individuals. The emergency highlighted the insufficiency of some traditional methods of psychological support for that part of the population concretely facing the risk of social isolation. This research aims to discuss an innovative methodology that, by exploiting information and communication technologies (ICT) resources, combines the need to protect the vulnerable population with the need to prevent their social isolation, by intervening on the psychological well-being of users most at risk. In particular, we want to evaluate the feasibility of a Cross Reality (XR) project that combines the technologies of Virtual, Mixed and Augmented Reality with the most consolidated therapeutic methods of Mindfulness and Art Therapy
