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
The Association of Parental Usual Source of Care and Child Health Care Utilization, Health Care Quality, and Functional Impairment Among Children with a Usual Source of Care
Full text linkObjective.
This Masters Paper sought to describe the demographic characteristics of United States children who have a usual source of care and examine child health care utilization, health care quality, and functional impairment by parental usual source of care status.
Methods.
Data were compiled from the 2016 Medical Expenditure Panel Survey Household Component. Analyses were restricted to a complete case sample of 7,388 children who reported having a usual source of care. All data editing and analysis was done using Stata statistical software. The independent variable of interest was a constructed parental usual source of care variable. The dependent variables of interest included sociodemographic items from the general survey, child health utilization and quality items from the Clinician and Group Consumer Assessment of Healthcare Providers and Systems questionnaire, and functional impairment items from the Columbia Impairment Scale. I utilized univariate and bivariate descriptive statistics along with Chi-square tests of significance to examine the relationships between parental usual source of care status and child health care utilization, health care quality, and functional impairment.
Results.
Among children with a usual source of care, there were significant differences in child sociodemographic characteristics and health care utilization by parental usual source of care status. Children whose parents did not have a usual source of care were significantly more likely to be younger in age (0-4 years old vs. 5-17 years old), Hispanic, poor (less than 100 percent of the federal poverty limit), and publicly insured compared to children whose parents had a usual source of care. Additionally, children whose parents did not have a usual source of care were significantly less likely to report that their child in the last 12 months: had an illness, injury, or condition that needed care right away, had routine care, had a doctor or parent who believed they needed care, tests or treatment, and had needed to see a specialist compared to children whose parents had a usual source of care. There were no significant differences in reported health care quality and functional impairment by parental usual source of care status.
Conclusions.
Health professionals, social service providers, and policymakers who wish to improve United States children’s health should consider the impact of parental usual source of care status on child health care utilization. Future research should seek to identify the potential mechanisms between parental usual source of care status and child receipt of health services.Master of Science in Public Healt
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
Infant and Young Child Feeding Practices in the Context of Natural Disasters: A Systematic Review
Full text linkThe Operational Guidance on Infant Young Child Feeding in Emergencies (IYCF-E) includes evidence-based recommendations for all emergency settings. A systematic review on infant feeding in the context of disasters was conducted to identify challenges unique to disasters and areas for future research. I searched Pubmed and Web of Science in May 2019 using the terms “breastfeeding” and “natural disasters”. Seven articles met eligibility criteria. Common themes identified across studies include low adherence to recommended IYCF practices, stress among mothers’, and vulnerability of IYCF to diarrhea and malnutrition. Further research is needed to better understand breastfeeding rates before and after a disaster event, the impact of caregiver stress on feeding practices, barriers to implementing global ICYF-E guidelines, and complementary feeding practices.Master of Public Healt
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
Interpersonal Violence and Hiv Sexual Risk Behaviors: The Influence of Alcohol Harm Reduction and Early Initiation of Sex Work Among Female Sex Workers in Mombasa, Kenya
Full text linkFemale sex workers (FSWs) are at high risk of interpersonal violence and HIV infection. The first paper investigated whether an alcohol harm reduction intervention was associated with reduced interpersonal violence or HIV sexual risk behaviors among FSWs in Mombasa, Kenya. The sample was comprised of 818 FSWs in Mombasa, Kenya who were 18 years or older, associated with HIV prevention drop-in centers and moderate risk drinkers. General linear mixed models examined associations between intervention assignment (alcohol harm reduction or nutrition intervention) and recent violence from paying and non-paying sex partners and HIV sexual risk behavior (engagement in sex work, total number of sex partners) at 6 and 12 months post-enrollment. The alcohol intervention was associated with statistically significant decreases in engagement in sex work and sexual violence from paying partners at 6 and 12 months post-enrollment and physical violence from paying sex partners at 12 months post-enrollment. Future research should explore mechanisms through which alcohol reduction leads to reduced violence among FSWs (i.e., reduced risk-taking, economic empowerment). More research is needed to understand whether alcohol reduction leads to reduced violence among FSWs who continue to engage in sex work or through discontinuation of sex work. Between 20-40% of FSWs worldwide began sex work before age 18. The second paper investigates whether early initiation of sex work (sex work at 17 or younger) was associated with recent interpersonal violence or HIV sexual risk behaviors. Logistic regression was performed, adjusting for drop-in center, current age, HIV status, and childhood abuse. Twenty percent of the sample reported early initiation of sex work. Early initiators were significantly more likely to experience recent physical and sexual violence from paying partners and less likely to report consistent condom use with paying partners. Early initiation was not associated with violence or HIV sexual risk with non-paying partners. FSWs who initiated sex work early are at particularly high risk of violence from paying partners. Interventions to prevent violence and reduce HIV sexual risk behaviors among adolescent FSWs and adult FSWs who initiated sex work early are needed. More work is needed to prevent early initiation of sex work.Doctor of Philosoph
