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
HIV Status Disclosure, Stigma and Viral Suppression among Adolescents and Young Adults Living With HIV
Get PDFThesis (Ph.D.)--University of Washington, 2022Introduction: Viral suppression remains the gold standard in determining success in HIV treatment. Adolescents and young adults with HIV (AYHIV) have poorer adherence and viral suppression than adults. Several factors have been associated with viral non-suppression among AYHIV through their influence on adherence. Individual level factors include younger age and male sex, sub-optimal dosing, and HIV-related stigma; interpersonal factors include low social support while health system factors include having treatment support cadre of staff and dedicated adolescent spaces in facilities. There is mixed evidence regarding the influence of social processes (including how one knew their HIV status [i.e., disclosure], stigma, and social support) on viral suppression in AYHIV. The WHO recommends that children between ages 6-12 years are informed of their HIV status through a planned and structured disclosure process involving their caregivers and providers. Few studies have described the disclosure experiences of AYHIV and their preferences especially following the roll out of disclosure guidelines and wider availability of disclosure tools in SSA countries since 2014. Methods: The aims of the dissertation address the following questions: Chapter 1) what is the prevalence and severity of HIV stigma among AYHIV, the co-occurrence of different stigma domains, and modifiable factors associated with HIV stigma? We used cross-sectional survey data from an observational study, Data-Informed Stepped Care (DiSC) to improve Adolescent HIV outcomes, among youth ages 15-24 years. Generalized linear models (GLM) were utilized to estimate the associations between modifiable factors and HIV stigma. Chapter 2) what is the impact of HIV stigma on mental health, treatment adherence and viral suppression? We used the longitudinal survey and routine data from the DiSC study to conduct longitudinal analyses, utilizing GLM for the analysis for viral suppression, and generalized estimating equations (GEE) for the analyses for depressive symptoms and treatment adherence. Chapter 3) what are the adolescent perspectives on the disclosure process, their experiences, preferences and perception of the impact disclosure had on their treatment and other aspects of life? We utilized cross-sectional survey data from the Adolescent Transition to Adult Care for HIV-infected Adolescents in Kenya (ATTACH) study for AYHIV ages 10-24 years, in addition using GLM to assess associations between modifiable factors associated with the disclosure process and satisfaction with disclosure. Results: Chapter 1: The mean overall stigma score for the 1,011 AYHIV was 25 (range: 10-50). The majority (88%) reported anticipated stigma, 48% perceived community stigma, 36% experienced stigma and 24% internalized stigma. Factors associated with higher stigma levels were AYHIV attending general/adult clinics compared to those in adolescent clinics, AYHIV having dropped out of school, being in a sexual relationship, exposure to violence. Some caregiver involvement in HIV care, and being in a support group were associated with lower mean stigma levels. Chapter 2: Among the 1,011 AYHIV, there were significant increments in risk of depressive symptoms, non-adherence and having a detectable viral load (>50 copies/ml) for every 1 standard deviation increase in stigma scores. Experienced and anticipated stigma were associated with detectable VL , while internalized and perceived community stigma were associated with depressive symptoms.
Chapter 3: Majority of the 375 AYHIV enrolled were disclosed to by providers, although 53% preferred that caregivers performed disclosure. Three-quarters preferred disclosure to be completed by age 12 years. Nearly three-quarters of AYHIV reported they were ready for disclosure when it happened, and 83% were satisfied with the process. Majority also reported that they felt supported by the clinic and caregivers pre-and post-disclosure. Lower support was associated with lower disclosure satisfaction. AYHIV reported that disclosure positively influenced their ART adherence. Conclusions: The studies in this dissertation identify key factors that may predict HIV stigma, and are likely amenable to interventions. This includes clinic structures that favor provision of adolescent friendly care, the school environment, and caregiver involvement in HIV care. The significant impact of HIV stigma on mental health, health behaviors and treatment outcomes demonstrated is an important catalyst for development of anti-stigma interventions. Lastly, we identified ways to improve the disclosure experience for AYHIV, especially through enhanced caregiver and clinic support throughout the process
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
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
