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
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
The Impact of HIV-Related Stigmatization on Medication Adherence among HIV-Infected People: A Test of Two Explanatory Mechanisms
No full textStigmatization (i.e., social discrediting and devaluation) due to HIV status may interfere with disease management among persons living with HIV (PLWHA) through associations with disclosure concerns and depressive symptoms. This study tested the hypotheses that disclosure concerns and depressive symptoms would mediate the association of stigma to treatment adherence (medication and clinic appointment adherence) in an outpatient sample of PLWHA (N = 174; 47% White, 41% African-American). Participants completed measures of stigma-related experiences, concerns about disclosing HIV status, depression, and medication adherence; chart data were obtained to characterize clinic appointment attendance. In the first set of analyses, simple mediation models indicated that disclosure concerns mediate the association between stigma and medication adherence (β = -0.097; 95% CI: -0.212 to -0.003), but not the association between stigma and clinic attendance. In the next set of analyses, depressive symptoms were shown to mediate both the stigma-medication adherence association (β = -0.113; 95% CI: -0.232 to -0.034) and the stigma-clinic attendance association (β = 0.397; 95% CI: 0.172 to 0.723). To augment these analyses, serial mediation models tested the serial effect of disclosure concerns on depressive symptoms in the stigma-treatment adherence association. The serial mediation analyses were significant (β = -0.025; 95% CI: -0.068 to -0.004 for medication adherence; β = 0.118; 95% CI: 0.039 to 0.237 for clinic attendance), providing evidence that stigmatizing experiences are negatively associated with medication adherence and missed clinic appointments indirectly through the serial effect of disclosure concerns on depressive symptoms. Disclosure concerns and depressive symptoms are two mechanisms worthy of further research to enhance our understanding of the association between HIV stigma and treatment adherence
Delay Discounting and Sexual Decision-Making: Understanding Condom Use Behavior among College Students
No full textCollege students are an at-risk group for sexually transmitted infections (STIs). Condoms provide an effective means of protection against STIs, however, condomless sex remains common among college students and intentions to use condoms do not consistently translate into condom use behavior. Informed by temporal self-regulation theory, the current study tested which indicator of condom use intentions from a delay discounting paradigm of condom-protected sex best accounted for variance in condom use behavior. The final sample consisted of 187 sexually active college students (51.9% female) who completed measures of self-reported condom use during vaginal and anal sex over the past three months and a decision-making paradigm regarding condom use intentions with hypothetical sexual partners. Three indicators of condom use intentions were calculated: initial intentions to use a condom when one was immediately available, the way in which initial intentions changed across delay trials (e.g., preference for immediate sex without a condom vs. delayed sex with a condom), and a composite measure. Path models were specified such that condom use behavior was regressed on each indicator of condom use intentions. Results showed that variations from one’s initial intentions to use a condom in favor of immediate sex without a condom across delay trials were significantly associated with condomless sex. The isolated effect of change in initial intentions across delay trials best accounted for variance in absolute frequency of condomless sex, whereas initial intentions best accounted for variance in relative proportion of condomless sex. Future research directions and implications for interventions 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
