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
Retention in care, viral suppression and factors associated with viral non-suppression among refugee adolescents infected with HIV at Kyangwali Refugee Settlement in Kikuube District, Uganda
No full textIntroduction: Compared to HIV positive non-refugee adolescents, refugee adolescents are generally less likely to receive antiretroviral therapy, and access to the drugs is often inconsistent (UNHCR, 2015). This study aimed to identify factors associated with viral non-suppression among refugee adolescents after at least six months of ART initiation, along with viral suppression and retention rates.
Main Objective: The purpose of this study was to determine the retention in care, the level of viral non-suppression, and identify the factors associated with viral non-suppression among refugee adolescents infected with HIV at Kyangwali re-settlement settlement.
Methods: A cross-sectional study of 246 HIV-positive refugee adolescents conducted between June to November 2021. These are adolescents registered on ART for at least 6 months and with at least one documented viral load in the last 12 months in Kyangwali refugee settlement in Kikuube district. Socio-demographics, clinical history, and treatment outcomes were collected using a questionnaire. Viral load status from routine medical records were used to determine treatment outcome. Epi-data software was used to enter the data, and STATA was used for both bivariate and multivariable logistic regression analyses to identify factors associated with viral non-suppression.
Results: Seventy-eight per cent (78%) of refugee adolescents achieved viral suppression. The viral suppression rates in this group was below UNAIDS' 95-95-95 targets. After six months on ART, 83.8% of respondents were still in care. This is significantly low when compared to national suppression rate for HIV positive adolescents. At bivariate logistical regression analysis level, adolescents (15-19) (crude Odds Ratio (OR) =2.1, 95% CI 1.05 - 4.16), males (crude OR =3.6, 95% CI 1.91 – 6.82), living 5 kms from the health facility (crude OR =2.3, 95% CI 1.25 – 4.30), not living with one’s parents (crude OR =2.3, 95% CI 1.10 – 4.87), history of TB disease (crude OR =4.7, 95% CI 1.73 – 12.10), intake of alcohol (crude OR =7.4, 95% CI 2.93 – 18.56) and adherence to ART (crude OR =3.8, 95% CI 1.59 – 9.13) were statistically significant with viral non-suppression.
After multivariable logistical regression analysis, living at a distance greater than 5 kms from the health facility (Adjusted Odds Ratio (AOR) = 2.5, 95% CI: 1.2 – 5.3), history of TB disease (AOR = 3.4, 95% CI: 1.07 – 10.6), intake of alcohol (AOR = 3.2, 95% CI: 1.0 – 9.9), poor adherence to ART (AOR = 3.6, 95% CI: 1.26 – 10.5) were statistically significantly associated with viral non-suppression.
Conclusion: Viral suppression among refugee adolescents is still below the target of 95%. Retention in care is suboptimal as well. Poor adherence to ART medication is strongly associated with viral non-suppression. The study shows that consuming alcohol, TB disease, having to travel long distances to access ART contribute significantly to the viral non-suppression in the refugee adolescents. Interventions are needed to ensure prompt intensive adherence counselling for adolescents with poor ART adherence, screening for TB as well as alcohol intake regularly, initiating TB preventive Therapy for all adolescents with negative TB screen
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
