Aspect of affective interferences and adhd symptomatology in children
No full textIn this paper, based on specific statistical method, we analyzed the relations between affective interferences and the probability of ADHD symptoms, as well as the presence of the predominant ADHD type in a sample of 142 children aged 8-12. The results showed a significant ADHD types
Aspects of Emotion Regulation Difficulties and Cognitive Deficit in Executive Functions Related of ADHD Symptomatology in Children
No full textIn this paper, based on specific statistical methods (correlations, analysis of variance), we analyzed the relations between
emotion regulation difficulties, cognitive functions deficit, and ADHD symptomatology. The results show a significant
relationship between emotion regulation difficulties and the presence of AD/HD symptoms. The study reveals the possibility
of using emotion regulation as an important indicator to be optimized in order to decrease the ADHD symptomatology and
increasing executive functions in children. As an interesting result, one can notice that ADHD symptomatology is increasing
with age, and thus with responsibilities involved by multiple tasks of daily life management in children

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
Trimetazidine improves post-ischemic recovery by preserving endothelial nitric oxide synthase expression in isolated working rat hearts.
No full textObjective: Previous investigations have consistently shown that the piperazine derivative trimetazidine (TMZ, 1-[2,3,4-trimethoxybenzil]
piperazine, dihydrocloride) has cardioprotective eVects in the experimental ischemia–reperfusion model. We tested the hypothesis that
cardioprotective eVect of TMZ is partly mediated by preservation of the endothelial barrier of the coronary microcirculation.
Methods: Isolated Wistar rat (250–300 g) hearts were subjected to a 15min period of global ischemia and 180min reperfusion in the
presence or absence of 1 M TMZ. Hemodynamic parameters, heart weight, creatinekinase (CK) release and microvascular permeability
(FITC–albumin extravasation) were evaluated. In addition, eNOS gene expression was estimated by rt-PCR, and eNOS protein levels
were assessed by Western analysis. In order to conWrm the involvement of NO in mediating the cardioprotective eVects of TMZ, 30 M
N-nitro-L-arginine methylester (L-NAME), a speciWc inhibitor of nitric oxide synthase, was used.
Results: After ischemia and reperfusion, TMZ produced a signiWcant improvement of mechanical function associated with a reduction
of CK release and FITC–albumin diVusion (P <0.001); the agent also resulted in improvement in coronary Xow (at 45 min +27% vs
control). The eNOS mRNA and protein levels were signiWcantly higher in TMZ-treated hearts compared to controls. The addition of
L-NAME signiWcantly reduced the beneWcial eVects of TMZ on contractile function, CK release and FITC–albumin diVusion.
Conclusions: in the isolated rat heart, TMZ exerts a relevant, NO-dependent, cardioprotection against ischemia–reperfusion injury
and preserves the endothelial barrier of the coronary circulation. This could contribute to explain the cardioprotective action of TMZ
following ischemia and reperfusio
