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
Pathways from Childhood Sexual Abuse to Sexual Risk Behaviour in MSM: A Mixed Methods Study
Get PDFMen who have sex with men (MSM) are disproportionately affected by childhood sexual abuse (CSA) compared to heterosexual men. CSA has been associated with a wide range of adverse outcomes later in life, including engagement in sexual risk behaviours (e.g., condomless anal intercourse), that place MSM at greater risk for HIV acquisition and transmission. Although the links between CSA and sexual risk are well-established among MSM, little research has investigated psychosocial factors that may mediate this relationship. Using a mixed-method approach, this study (a) explored psychosocial factors as pathways linking a composite of complex CSA experiences (i.e., CSA complexities) with sexual risk (N = 297 HIV-uninfected men; Mage = 38.0, SD = 11.6) and (b) drew upon the perspectives and experiences of a subset of MSM with histories of CSA (n = 39). Mediation analyses provided some support for hypotheses. CSA complexities were positively associated with sexual risk behaviours (i.e., condomless anal and/or vaginal intercourse) cross-sectionally and negatively associated with change in sexual risk behaviours over time. CSA complexities had a positive indirect effect on sexual risk behaviours only through the PTSD avoidance symptom cluster cross-sectionally, but not over time. There were no significant indirect effects of CSA complexities on sexual risk behaviours through substance use and other PTSD symptom clusters both cross-sectionally and over time. Thirty-nine audio recorded and transcribed impact statements were analyzed to provide insight into how CSA is related to cognition, affect, behaviour, and resilience among MSM. Findings are discussed in terms of their implications for informing HIV prevention interventions
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
Bullying and Body Image: Body image disturbance in emerging adults with a history of bullying victimization
Get PDFBeliefs about body image that are shaped in childhood and adolescence often continue into emerging adulthood, a developmental period encompassing ages 17-29 years. Bullying is “behaviour intended to inflict injury or discomfort upon another individual.” Appearance related teasing is a form of bullying where individuals are victimized based on an aspect of their appearance. Those who experienced childhood or adolescent bullying with appearance related teasing have been found to be at a higher risk of expressing extreme body image disturbances up to and including clinical disorders such as Body Dysmorphic Disorder (BDD). With the introduction of the Muscle Dysmorphia (MD) specifier into the BDD diagnostic category in the DSM-5, there is also a need for more research into understanding how experiences of bullying are associated with MD. The current study explored the relationship between childhood or adolescent bullying, appearance related teasing and body image disturbance up to and including BDD and MD among a sample of emerging adults. Participants who experienced both underweight and overweight appearance related teasing had increased body image disturbance demonstrated by the presence of BDD and MD symptoms. Additionally, both men and women were more likely to exhibit MD symptoms after being teased for being underweight. These results contribute to the growing body of literature on bullying and body image and contribute to our understanding of MD by further linking the presence of MD symptoms among those with a history of being bullied. Further, the results of this study can be used to inform clinical interventions for those experiencing body image disturbance following a history of being bullied related to an aspect of their appearance
Body Image Disturbance and Social Networking Site Behaviours
Get PDFSocial Networking Sites (SNSs) are becoming increasingly popular in modern society, with emerging research indicating that appearance focused SNS use in particular is associated with body image concerns. The present study investigated body image disturbance and appearance related SNS behaviours, including engaging in appearance comparisons and self-photo (“selfie”) activities. A sample of 358 Canadian university students (259 females and 93 males) aged 17 to 57 years (M = 21.93 years, SD = 5.30 years) completed an online questionnaire consisting of self-report measures assessing body image disturbance, appearance comparison, selfie taking, selfie sharing, selfie investment, and selfie editing. Results indicated that body image disturbance was associated with greater degrees of appearance comparison, selfie investment, and selfie editing, as well as less frequent selfie sharing online. Frequency of selfie taking was not associated with body image disturbance. Further, the link between body image disturbance and selfie editing was found to be partially mediated by appearance comparison. Appearance comparison did not serve a mediational role for the associations between SNS use nor selfie sharing with selfie editing behaviour. Findings from this study revealed notable sex differences, with females reporting significantly higher body image disturbance and greater frequencies of the appearance related SNS behaviours measured. Implications and future research directions are discussed
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
