Likelihood of condom use when sexually transmitted diseases are suspected: results from a clinic sample
No full textObjective. To determine the event-level associations between perceived risk of sexually transmitted disease (STD) acquisition/transmission and condom use during penile–vaginal intercourse (PVI) among STD clinic attendees. Method. A convenience sample (N = 622) completed daily electronic assessments. Two questions were proxies of perceived risk: suspicion that the partner might currently have an STD and that “you” might currently have an STD. Participants reported whether condoms were used with PVI events in the past 24 hours. Generalized estimating equations determined the association between each of the perceived risk variables and event-level condom use. Results. For the model pertaining to suspicion of sex partner infection, there were 16,674 events of PVI, with condom use during 10,552 of these events. The effect of current suspicion was significant after adjusting for gender and whether participants identified as African American/Black (estimated odds ratio = 2.17, 95% confidence interval = 1.57-3.00, P = .0001). The model pertaining to suspicion of self-infection included 16,679 events of penile–vaginal sex, with condom use during 10,557 of these events. Again, the effect of current suspicion was significant after adjusting for gender and African American/Black race (estimated odds ratio = 2.05, 95% confidence interval = 1.43-2.40, P = .0001). Tests for interactions with gender and with race were nonsignificant (all Ps > .25). Conclusion. Using an event-level research design, strong associations were found between perceptions of STD risk and condom use in a clinical population. Health care providers and other professionals may indirectly promote condom use by helping clinic patients realistically evaluate their risk of having sex with infected partners or of being a source of STD transmission to others
Negative perceptions about condom use among a clinic population: comparisons by gender, race, and age
No full textObjectives:We sought to elucidate the associations of 13 items assessing negative perceptions about condom use with gender, age, and race in a sample of clinic attendees.Methods:Patients from 4 clinics, in three US cities, were recruited (N=928). Data were collected using audio-computer assisted self-interviewing. The primary measure was a 13-item adapted version of the Condom Barriers Scale. Logistic regression and chi-square tests were employed to relate the 13 items to gender, age, and race.Results:Gender, race, and age all had significant associations with negative perceptions of condoms and their use. A primary finding was a large number of significant differences between men and women, with negative perceptions more common among women than men. For African Americans, especially women, negative perceptions were more common among older participants than among younger participants.Conclusions:Important demographic differences regarding negative perceptions may inform the tailoring of intervention efforts that seek to rectify negative perceptions about condoms and thus promote condom use among individuals at risk for STIs in the US. On the other hand, our findings also suggest that the majority of STI clinic attendees may hold positive perceptions about condoms and their use; maintaining and building upon these positive perceptions via education, counseling, and access is also important
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
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
