Trace elements among a sample of prisoners with mental and personality disorders and aggression: correlation with impulsivity and ADHD indices
Objectives: Mental, personality and substance use disorders are over represented among prisoners and aggressive individuals. The psychopathological and biological markers linked to mental functioning remain still unclear. In particular, the role of trace elements in mental illness is still matter of debate. Here, we investigated whether trace elements are correlated to specific psychopathological phenotype groups. Methods: Axis I and II disorders, aggression, impulsivity, adult attention deficit/hyperactivity disorders (ADHD) indices and serum levels of zinc, copper and cadmium were evaluated in 160 male prisoners. Results: Using latent class analysis we could subdivide prisoners into three distinct psychopathological classes: Class 1 characterized by low prevalence of aggression, personality disorders and substance abuse/dependence (alcohol, cannabis, cocaine); Class 2 represented by low prevalence of aggression and high prevalence of personality disorders and substance abuse/dependence; Class 3 defined by high prevalence of aggression, personality disorders and substance abuse/dependence. Serum levels of zinc were higher in Class 2 and 3 compared to Class 1. Moreover, Class 3 was associated with higher scores of impulsivity and ADHD indices. Conclusion: Our results suggest that impulsivity but also adult ADHD indices are related to aggressive behaviour, and higher zinc levels are linked to personality disorders and addictions, but not to aggression
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
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
Dispelling the Myths Behind First-author Citation Counts
We conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
We have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
Prédire le comportement suicidaire des détenus avec le Suicide Probability Scale et des variables actuarielles
La problématique du suicide en milieu carcéral est connue et décrite dans plusieurs recherches. Toutefois les outils de dépistage du risque suicidaire ont surtout été développés pour des populations à risque non carcérales et la capacité de prédiction de ces échelles n'a été inférée qu'indirectement. Depuis un peu plus de dix ans, le questionnaire Suicide Probability Scale (Cull et Gill, 1988) est utilisée auprès de détenus québécois qui débutent une sentence fédérale. Cependant le survol de la littérature n'a pas permis de retrouver d'étude psychométrique liée à la validité prédictive de ce questionnaire auprès d'une population spécifiquement carcérale. L'objectif de la présente recherche était donc d'évaluer la valeur prédictive du questionnaire Suicide Probability Scale (SPS) auprès d'une population masculine carcérale.La recherche vise à vérifier si les détenus dépistés à risque modéré ou élevé en 1995-1996 par le SPS ont effectivement eu des comportements suicidaires par la suite, pendant qu'ils étaient encore sous la responsabilité des services correctionnels. Les résultats sont basés sur une période d'observation globale de 11 ans et demi (entre 1995 et 2006) et confirment que le SPS, dans sa forme actuelle, permet de prédire le comportement suicidaire. Une amélioration de la prédiction du risque suicidaire est démontrée si le point de découpage est modifié de 50 (point de démarcation actuel des auteurs du SPS) à 40 pour la clientèle spécifique des hommes incarcérés dans un pénitencier. Les résultats obtenus au SPS permettent aussi de dépister les détenus à risque de comportement hétéro-agressif en milieu carcéral. Le deuxième article a évalué la valeur prédictive de 24 variables actuarielles, connues en début de sentence, en combinaison avec le SPS, afin d'augmenter la prédiction et de la rendre plus spécifique en réduisant le nombre de faux négatifs.La capacité de prédiction a été analysée avec des modèles de régression logistique et la valeur sous la courbe ROC. L'ajout d'une ou de deux variables actuarielles permet d'améliorer le dépistage des comportements suicidaires sur une période de 24 mois et même de 120 mois
