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
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
Impact of Parent’s HIV Status on Their Uninfected Child—A Comparative Analysis of the Child’s Healthcare Utilization, Access and Health Outcomes
Get PDFWith the advent of effective antiretroviral medication and increased expectancy of life span among HIV-infected individuals has lead to an increase in the at-risk population of uninfected children living with their HIV-infected parent(s). The purpose of this study was to investigate the impact of parent’s HIV status on their child’s access to healthcare resources, healthcare utilization and health outcomes.
This was a cross-sectional study in which the information on the children of HIV seropositive parent(s) was collected through a face-to-face interview of the HIV-infected parents having children currently residing with them. The comparative group comprising of children of HIV seronegative parents was obtained from the Medical Expenditure Panel Survey (MEPS) 2006 database. HIV seronegative children aged between 2 yrs and 15 yrs of HIV seropositive as well as HIV seronegative parent(s) were included in this study. A parent was identified as HIV seropositive if they had a prior diagnosis of HIV/AIDS (ICD-9-CM 042, 043, V08) by a physician and had at least one record of a HIV positive serological test result in the past 6 months in their medical records. A parent was defined HIV seronegative if there were no diagnosis of HIV/AIDS (ICD-9-CM 042, 043, V08) in their medical records in MEPS 2006 database. Each child of HIV seropositive parent (primary group) was matched with two children of HIV seronegative parents (comparative group) using the Mahalanobis Distance Metric matching including the propensity score technique. Bivariate and two step multivariable logistic and negative binomial regression analysis was conducted to assess the relationship between the parent’s HIV status and potential variables of interest.
Upon matching, 89 children of HIV seropositive parent(s) matched with 178 children of HIV seronegative parents (1:2 ratio), thus making the final study sample of 267 participants. No differences were observed between the groups in terms of their mean age (8.47 vs 8.94 yrs, p=0.6265), parent’s age (33.57 vs 34.21 yrs, p=0.9464) and other socio-economic and parent’s health insurance variables. This study found no difference between the children in terms of their access to health insurance (97.75% vs 96.63%, p=0.7227) and access to regular source of medical care (87.64% vs 86.68%, p=0.4453). However, a larger number of children of HIV seropositive parent(s) had prescription insurance (95.51% vs 16.29%, p=\u3c0.0001) compared to children of HIV seronegative parents. Also, children of HIV seropositive parent(s) took more time and expressed having difficulty in getting to a healthcare provider compared to children of HIV seronegative parents. Children of HIV seropositive parent(s) were 1.682 times (95% CI: 1.115-6.453) more likely to have a physician visit and had 49% (p=0.0206) more visits to a doctor than the children of HIV seronegative parents. No differences were observed in the likelihood of the children in having a hospital visit or an emergency room visit. However, among children who had a hospital visit and among those who had an emergency room visit, children living with their HIV seropositive parent had 3.0 times more hospital visits (p=0.0244) and 86% more emergency room visits (p=0.0464) compared to children living with HIV seronegative parents, respectively. No relationship was noted between the parent’s HIV status and the child’s absenteeism in school/daycare due to illness (OR: 0.938, 95% CI: 0.425-2.069). However, children of HIV seropositive parent were 4.041 times more likely (95% CI: 1.887-13.471) to be overweight. Though no difference in the likelihood of these children being currently on prescription medication was observed (OR: 0.918, 95% CI: 0.413-2.042), among those who were currently on any medication, children of HIV seropositive parent(s) were more likely to be on a medication for a mental health problem (OR: 5.520, 95% CI: 1.503-20.276).
This study concluded that HIV status of the parent has significant impact on the child’s access in getting to a healthcare provider. It was also found that children of HIVinfected parent(s) had higher utilization of physician’s visits. Higher incidences of obesity and consumption of psychotropic medications among children of HIV seropositive parent(s) signify serious impact of the parent’s HIV status on the nutrition and psychological growth of the child. Further studies are recommended to investigatethe exact cause and long term impacts of the findings observed in this study
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.
