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
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
A study to evaluate the effectiveness of HIV Post Exposure Prophylaxis interevention in sexually abused Children presenting to the University Teaching Hospital,Lusaka
Get PDFChild sexual abuse (CSA) is a growing global problem. In Zambia, CSA was found to be a
significant concern in Lusaka and to be associated with a high risk of HIV infection. CSA provides
an increasing but highly unfortunate avenue of paediatric HIV infections among Zambian children.
OBJECTIVE
The aim of the study was to determine the incidence of the human immune deficiency virus (HIV)
transmission and the effectiveness of HIV post exposure prophylaxis (PEP) intervention among
sexually abused children who presented to the University Teaching Hospital (UTH).
RESEARCH DESIGN AND METHODS
A cohort of HIV negative female children aged less than 16 years of age presenting with child sexual
abuse to the UTH in Lusaka, were recruited over a period of 13 months and conveniently grouped
into two study arms based on the time of presentation to UTH. Cases presenting at less than 72 hours
post exposure {given HIV post exposure prophylaxis (HHIV-PEP)}, whilst controls presented after
72 hours (not given HIV-PEP). The participants had an HIV Polymerase Chain Reaction ( PCR) test
done at baseline and a follow up test done after one month.
RESULTS
A total of 376 clients were enrolled into the study with 239 cases and 137 controls. Only 166
participants were retained at one month (106 cases and 60 controls) with an overall retention rate of
44%. The overall HIV infection rate among children that came for the second visit was 2.4% (4/166).
The HIV infection rate was 1.7 % among controls and 2.8% among cases. However, among cases that
received HIV-PEP but did not finish the full PEP course, the HIV infection rate was 15.8%, whilst
there were zero infections among those that completed HIV- PEP (p=0.005). Risk of HIV infection
was about 16 times more in children that did not complete the full course of PEP compared to
children completing PEP.
Young adolescents (10 -15 years) were more frequently sexually abused, comprising about 70% of
the cases. Kanyama-John Laing, Mtendere-Kalingalinga, and Chawama-Kuku-Misisi residential areas
were the places with most occurrences of child sexual abuse cases. Most frequently, the perpetrator
was a person well known to the child, either the neighbour or boyfriend. The majority of the cases
(64%) sought PEP intervention within the recommended time frame of within 72 hours. Important
influencers of seeking PEP early or starting PEP were age of child (OR: 0.33, CI: 0.13 - 0.86, p =
0.02), abuser's relationship (OR: 0.49, CI: 0.26 - 0.93, p = 0.03), and residence (OR: 2.78, CI: 1.16 -
6.67, p =0.02).
CONCLUSION
The overall HIV infection rate was 2.4% following child sexual abuse in children presenting to the
University Teaching Hospital (UTH), Lusaka regardless of HIV-PEP Administration. However, this
could not be generalized to the entire population due to the small sample size and the high drop-out
rate of 56% in the study. When HIV PEP was administered, there was no significant difference in
HIV infection based on early (within 36hours) or late (36 to less than 72 hours) presentations.
However, the risk of HIV infection was about 16 times more in children not completing PEP
compared to children completing PEP. Therefore, HIV PEP is effective in reducing the risk of HIV
infection following CSA only when it is administered correctly and for the correct duration. The age
of the child, relationship of defiler to the child and residence are significant predictors for early
presentation for HIV PEP

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.
