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
Improving STI/HIV passive partner notification using quality improvement methods in Malawi
Full text linkA research report submitted to the Faculty of Health Sciences, University of Witwatersrand-School of Public Health, in partial fulfillment of the requirements for the Master of Science (MSc) degree in Epidemiology – Implementation Science.
April 18, 2018.Introduction
Human Immunodeficiency Virus (HIV) and other curable Sexually Transmitted Infections (STIs) constitute a large public health burden world-wide. The control of HIV and STIs is incomplete if sexual partners of individuals with HIV and STIs are not identified and treated. The proportion of sexual partners that present to health facilities for screening and treatment is low in the sub-Saharan African (SSA) region. A recent study in Malawi reported a sexual partner referral proportion of 24% through passive partner notification. Several other approaches to partner notification (PN) have been shown to be feasible, acceptable and cost-effective for SSA. However, passive PN is widely used as the standard of care (SOC) and is the most preferred approach for resource-limited settings including Malawi. The low proportion of sexual partner referral points to the need to improve the efficiency and effectiveness of the SOC method of PN in order to realize a better yield of sexual partners in Malawi and SSA.
Methods
A pre- and post-intervention quasi-experimental study was conducted at Bwaila STI Unit (BSU) in Lilongwe Malawi from January to June 2017. At baseline, we estimated the proportion of sexual partner referral and identified health system-related factors that influenced PN at BSU through interviews with health workers and clinic observations. Based on the baseline findings, a three-prong intervention was designed through expert consultation and implemented with a quality improvement (QI) team using the model for improvement (MFI). The intervention included: early start time of the clinic; shortening of the group health talk and expedited clinic flow for sexual partners. Each intervention was tested twice through 1-week long test cycles and then combined into one package and tested twice. Process data were collected and monitored using run charts. We used run charts to assess for non-random signals of change in the PN process and assessed for a 10%
increase in the sexual partner referral proportion between the pre- and post-intervention periods at 95% power and at α=0.05.
Results
At baseline, the proportion of sexual partner referral was 15.6%. Experts included BSU staff, research staff and Ministry of Health officials who were involved in the selection of interventions based on findings from the interviews and clinic observations. The QI team consisted of the investigator, a nurse-in-charge, a counselor, a clinic receptionist and a clinic aide who championed implementation of the intervention. In the post intervention period, we assessed 267 patient records. The median age was 29 years and 56% were female. Out of the three interventions, the team managed to shorten the duration of the group health talks from 56 minutes to less than 40 minutes and expedited the clinic flow for partners by reducing the duration of clinic stay by 45 minutes. However, the target clinic start time of 08:00 hours was not achieved. The post-intervention proportion of sexual partner referral was 21.4% representing a statistically significant increase of 37% (P=0.04). There was an upward trend in data points on the run chart which was indicative of a non-random signal of improvement in the proportion of sexual partners.
Discussion
Our results demonstrate that passive PN can be successfully improved through use of the model for improvement in Malawi and suggest that our intervention was highly effective at increasing the proportion of sexual partner referral. However, despite this increase, the proportion of sexual partner referral remains suboptimal. More effort is required to increase the proportion of sexual partner referral in Malawi.LG201
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

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.
