Psychosocial Treatment for Drug Dependence
No full textAll randomized controlled studies published in international peer-reviewed journals up to July 1999 were meta-analysed with the aim of studying the effect of psychosocial interventions on patients with drug dependence. Systematic literature searches were administered by SBU. In all 104 studies were screened and rated according to the 12 dimension quality score of SBU. The analyses in the chapter studied the effects on drug abuse and retention and aimed at specific domains of research; 1) efficacy of treatment of opiate abuse/ depen¬dence (n=24) containing 5.721 patients, 2) of cocaine abuse/dependence, 26 studies with 5.956 patients), 3) cannabis abuse, (7 studies with 707 patients), 4) of treatment methods for patients with mental illness and (9 studies), 5) residential treatment containing 9 studies and 4.867 patients, 6) finally for structure interventions with other outcome measures than drug use, 5 studies with 461 patients. A clinical methodological model elaborated from Wolberg´s (1988) classification, divided the interventions into three groups: ranging in therapist skills, goals and costs from a) supportive, b) reeducational to c) psychotherapeutic intervenetions. Effect sizes were calcylated using Hedge´s d and groups of interventions were weighted with the root of the variance. In opiate abuse re-educational and psycho-therapeutic interventions had a significant but low Wd of .23 and .29 respectively. Re-educational interventions only gained a significant but low effect size of Wd = .24 in treatment of cocaine abuse. Family therapies finally were efficient in the treatment of teenage cannabis abusers in with an intact family network. Supportive interventions, generally, were not effective. For retention as outcome measure, finally, psychotherapies had a significant medium effect size in retention of opiate abuse (Wd= .56, n=3.380) and a low but significant positive effect size in retention of cocaine abuse (Wd= .30, n=3.381)
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
