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
School-based education programmes for the prevention of child sexual abuse

Abstract\ud
\ud
Background \ud
\ud
Child sexual abuse is a significant global problem in both magnitude and sequelae. The most widely used primary prevention strategy has been the provision of school-based education programmes. Although programmes have been taught in schools since the 1980s, their effectiveness requires ongoing scrutiny. \ud
\ud
Objectives \ud
\ud
To systematically assess evidence of the effectiveness of school-based education programmes for the prevention of child sexual abuse. Specifically, to assess whether: programmes are effective in improving students’ protective behaviours and knowledge about sexual abuse prevention; behaviours and skills are retained over time; and participation results in disclosures of sexual abuse, produces harms, or both. \ud
\ud
Search methods \ud
\ud
In September 2014, we searched CENTRAL, OvidMEDLINE, EMBASE and 11 other databases.We also searched two trials registers and screened the reference lists of previous reviews for additional trials. \ud
\ud
Selection criteria \ud
\ud
We selected randomised controlled trials (RCTs), cluster-RCTs, and quasi-RCTs of school-based education interventions for the prevention of child sexual abuse compared with another intervention or no intervention. \ud
\ud
Data collection and analysis \ud
\ud
Two review authors independently assessed the eligibility of trials for inclusion, extracted data, and assessed risk of bias.We summarised data for six outcomes: protective behaviours; knowledge of sexual abuse or sexual abuse prevention concepts; retention of protective behaviours over time; retention of knowledge over time; harm; and disclosures of sexual abuse.

Assessing the effectiveness of school-based sexual abuse prevention programs
No full textThis article highlights the importance of systematic reviews for research synthesis, with the strength of this approach demonstrated through the authors’ recent Cochrane review into the effectiveness of school-based programs for the prevention of child sexual abuse. It describes the features of evaluation studies and the differences between systematic reviews and more traditional literature reviews, before summarising the findings of their recent Cochrane review
School-based programs for prevention of child sexual abuse: A Cochrane systematic review and meta-analysis
No full text<b>Objective</b>\ud
\ud
To assess evidence of the effectiveness of school-based education programs for the prevention of child sexual abuse. The programs deliver information about child sexual abuse and strategies to help children avoid it, and encourage help seeking.\ud
\ud
<b>Methods</b>\ud
\ud
Systematic review including meta-analysis, of randomised controlled trials, cluster randomised controlled trials, and quasi-randomised controlled trials.\ud
\ud
<b>Results</b>\ud
\ud
Twenty-four studies with 5802 participants were included. Child self-protective skills [(OR=5.71 (CI 1.98, 16.51)], factual [SMD=0.61 (0.45, 0.78)] and applied knowledge [SMD=0.45 (0.24, 0.65)] increased in the intervention group, and knowledge gains were retained at 6-months [SMD 0.69 (0.51, 0.87)]. There were no differences in anxiety or fear [(SMD -0.08 (0.22, 0.07)], and findings regarding disclosure of abuse were inconclusive.\ud
\ud
<b>Conclusions</b>\ud
\ud
Children’s self-protective skills and knowledge can be increased by participation in school-based sexual abuse prevention programs. However, it is unknown whether gains in skills and knowledge actually decrease the likelihood of child sexual abuse
