Cannabis en los jóvenes: patología psiquiátrica y escalas de consumo
Get PDFEl cannabis es la droga ilegal de uso más extendido en España siendo la prevalencia de
su consumo elevada (17% en el último año-población de 15 a 34 años).
Dado que diversos estudios muestran que sólo una pequeña proporción de personas
con abuso o dependencia de cannabis buscan tratamiento, para detectar un consumo
patológico se hace necesario disponer de instrumentos que se puedan utilizar tanto en
atención primaria como en las encuestas a población general o escolar.
Por otro lado, teniendo en cuenta la asociación entre problemas mentales y consumo
de sustancias (comorbilidad psiquiátrica) y dado que en nuestro país no existen
estudios de morbilidad psiquiátrica en población joven consumidora de cannabis fuera
de tratamiento, es de interés estudiar la patología psiquiátrica asociada a dicho
consumo en una muestra de sujetos jóvenes reclutados fuera del marco asistencial.
Este estudio se diseñó para dar respuesta a estas deficiencias.El cànnabis és la droga d’ús il·legal més extensa a Espanya sent la prevalença del seu
consum elevada (17% en l’últim any-població de 15 a 34 anys).
Donat que diversos estudis mostren que només una petita proporció de persones amb
abús o dependència de cànnabis busquen tractament, per a detectar un consum
patològic és necessari disposar d’instruments que es puguin utilitzar tant en atenció
primària como en las enquestes a població general o escolar.
Per una altra banda, tenint en compte l’associació entre problemes mentals y consum
de substàncies (comorbiditat psiquiàtrica) i donat que en el nostre país no existeixen
estudis de morbiditat psiquiàtrica en població jove consumidora de cànnabis fora de
tractament, és d’interès estudiar la patologia psiquiàtrica associada a aquest consum
en una mostra de subjectes joves reclutats fora del marc assistencial.
Aquest estudi va ser dissenyat per donar resposta a aquestes deficiències.Cannabis is the illicit drug most widely used in Spain being prevalence of consumption
high (17% in the last year-population 15-34 years).
Since studies show that only a small proportion of people with cannabis abuse or
dependence seek treatment, to detect abnormal consumption is necessary to have
instruments that can be used both in primary care and in general population surveys or
school.
On the other hand, given the association between mental health problems and
substance use (psychiatric comorbidity) and given that in our country there are no
studies of psychiatric morbidity in young people consuming cannabis off treatment, is
of interest to study psychiatric disorders associated this consumption in a sample of
young subjects recruited outside the care setting.
This study was designed to address these shortcomings.Programa de doctorat en Biomedicin

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
No full textWe 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
