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

Training in child and adolescent mental health for nursing, occupational therapy and social work students: does it influence career intentions?
Full text linkDespite increased funding in child and adolescent mental health there remains a shortage of qualified health professionals working in this area in New Zealand. This study was designed to determine whether increasing training in child and adolescent mental health would increase undergraduate nursing, occupational therapy and social work students’ interest in working in the area. An additional aim of the study was to develop a sustainable teaching resource on child and adolescent mental health in CD-Rom format.
Students participating in the study were asked to complete a questionnaire before and after attending a workshop in child and adolescent mental health and again at a follow-up point, three to 16 weeks later, to establish whether or not this had influenced their stated career intentions. To assess students’ and their educator’s perceptions of the quality and acceptability of the workshop a quality of teaching questionnaire was administered after the workshop.
Three-hundred-and-seventy-three students participated in 14 workshops held in seven cities around New Zealand. The workshop had a positive impact on students’ career intentions in relation to child and adolescent mental health. A repeated measures analysis showed an overall time effect (F2,546 = 16.29, p = <0.0001). Further investigation of this difference was carried out using a multiple comparison test (Scheffe test) which showed a highly significant positive increase in career intentions between pre-workshop and post-workshop ratings (p = <0.0001), which dropped between post-workshop and follow-up (p = 0.004), with no change between pre-workshop and follow-up ratings (p = 0.43). There was no differential effect by students’ professional group (p = 0.08), ethnicity (p = 0.6), gender (p = 0.75) or age (p = 0.26).
The study reflected similar career intention trends found in the literature. In particular, at base-line there were differences in profession-specific career intentions. Job attributes such as job satisfaction, personal interest, a job with supports available and being able to help people were also factors influencing students’ career intentions. The present study showed that a workshop on child and adolescent mental health had a significant immediate impact on undergraduate students’ career intentions
Evaluation of a computerised cognitive behavioural therapy program for depressive symptoms in sexual minority youth
No full textIn this thesis I have described a body of work designed to address the problem of depression in sexual minority youth. I started by determining whether sexual minority youth have unique mental health and help-seeking needs. Subsequently the primary aim of my doctoral project was to design and evaluate the acceptability of a self-help program, specifically a computerised cognitive behavioural therapy (CCBT) program specially adapted for sexual minority youth with mild to moderate depressive symptoms. This thesis comprises four studies. In Study One I used multiple logistic regression to examine the associations between sexual attraction and depressive symptoms, suicidality, self-harming and help-seeking behaviours, in data collected from a nationally representative secondary school health and well-being survey (Youth'07). Sexual minority students consistently had higher prevalence estimates of depressive symptoms (p=<0.0001), suicide attempts (p=<0.0001) and selfharming (p=<0.0001) than students attracted to the opposite sex. Students who reported they were attracted to both sexes had the highest odds ratios for depressive symptoms (OR 3.7, 95% CI 2.8-4.7), suicide attempts (OR 7.0, 95% CI 5.2-9.4) and self-harm (OR 5.8, 95% CI 4.4-7.6). Non-heterosexual students were more likely to report having seen a health professional for an emotional worry and having difficulty accessing help for emotional concerns. For Study Two, I used thematic analysis based on the general inductive approach to analyse the results of three focus groups. In these groups nine sexual minority participants discussed the unique challenges they face and whether these challenges could usefully be addressed in a CCBT program. Participants also provided feedback on prototypes of a 3D fantasy-based role-play CCBT program (SPARX), designed for a general youth population, and made suggestions about how SPARX could be adapted for sexual minority youth. Participants reported experiencing a number of challenges in their day-to-day life including living within a homophobic and gender-stereotyped world. They highlighted issues unlikely to be experienced by their heterosexual or oppositesex attracted peers related to discrimination and mistreatment due to their sexuality. As a result of participants' feedback a specially modified version of SPARX, called SPARX: The Rainbow Version, was developed for sexual minority youth. In Study Three I conducted an open trial to assess the acceptability and feasibility of SPARX: The Rainbow Version (or Rainbow SPARX) amongst 21 sexual minority youth with depressive symptoms. I also collected preliminary data on the efficacy of Rainbow SPARX. The depressive symptoms of sexual minority youth (assessed using the Child Depression Rating Scale - Revised) decreased significantly post intervention (p<0.0001), with a large pre- to post-effect size (d=1.01) and this positive change was maintained at three-month follow-up. There were also significant improvements on secondary outcomes including self-rated symptoms of depression and anxiety, and a reduction in hopelessness. Over 80% of the sexual minority youth completing SPARX: The Rainbow Version thought CCBT would appeal to other young people. The results from the open trial were compared with those of a randomised controlled trial, where 154 exclusively opposite-sex attracted youth were equally randomised to SPARX and treatment as usual (TAU). With the exception of mean age of participants, open trial and RCT participants did not differ significantly in terms of baseline demographic data, baseline clinical characteristics and changes in assessment scores over time. However, open trial participants were more likely to complete treatment when compared with RCT participants (p=0.007). Study Four was a qualitative study which involved analysing the results of semi-structured interviews using the general inductive approach. Interviews were conducted with 25 youth immediately after they completed SPARX: The Rainbow Version. Twenty of these interviews were with open trial participants from Study Three. Of the remaining five interviews, four interviewees did not have depressive symptoms at baseline and one interviewee identified as being 'straight'. Seventeen participants reported that SPARX: The Rainbow Version helped them feel better or less depressed and most of the participants reported that the program included useful messages or content. The majority liked the look and feel of the program. Eighteen participants highlighted minor technical issues that they thought needed to be addressed. Participants in Study Four also identified suggestions or tips that would help encourage sexual minority youth to participate in future research. I have shown that, relative to their peers, sexual minority youth are more likely to have depressive symptoms and to experience difficulty accessing appropriate healthcare. To address these issues I sought the views of sexual minority individuals and then incorporated their views into an adapted form of CCBT for sexual minority youth. Taken together the results of my open trial (Study Three) and the qualitative study (Study Four) indicate that SPARX: The Rainbow Version shows promise as an intervention for mild to moderate depressive symptoms in sexual minority youth and that this intervention was acceptable to participants and that delivery was feasible
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

Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
