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
Evaluation Of The Capacity To Appropriately Diagnose And Treat Malaria At Rural Health Centers In Kabarole District, Western Uganda.
No full textSetting: Malaria has remained the leading cause of morbidity,
responsible for 47% of the total causes of ill health at the outpatient
department, in Kabarole District for over ten years. In Uganda, the
malaria treatment policy changed the first-line treatment from
chroloquine and sulfadoxine/pyrimethamine (SP) to artemisinin-based
combination therapies in 2005, necessitating building new technical and
infrastructural capacities. Objective: This study evaluated the status
of the capacities and practices to appropriately manage malaria in a
rural setting following the new guidelines. Methods: A stratified
random sample of 16 heath facilities was selected from public and
private not for profit health centres. We used a pre-tested
interviewer-administered questionnaire to interview 26 health workers,
and observation checklists to assess essential equipment, supplies,
anti-malarial medicines, human resources and treatment practices. Data
analysis was done with Epi-Info soft ware. Procedure observations made
were coded according to the emergent themes and frequencies calculated.
Results: More than 75% of the respondents had little knowledge on basic
facts about malaria and 54% did not know the new malaria treatment
policy. Over 50% health workers did not understand the rationale for
intermittent preventive treatment and 65% had never had refresher
training about malaria management. At least 65% mentioned AL as the
first-line anti-malarial treatment and 73% mentioned parental quinine
as a drug of choice for complicated malaria. Over 80% health facilities
had experienced stock-outs of artemether/lumefantrine (AL) and SP
within the 3 months prior to the study. Only one health centre had 80%
of the minimum required staff. Malaria treatment policy guidelines
lacked in 86% health facilities, microscopes in 50%, while 100% lacked
insecticide-treated bed nets. All clinicians spent inadequate time i.e.
less than (10-19 minutes) with malaria patients, 82% never conducted
physical examination, 92% never checked for anemia and 67% never
weighed patients. Conclusion: The district has very low capacity to
manage malaria correctly according to the guidelines. The study
recommends regular refresher training of health workers on malaria
policy and additional support to health facilities to improve their
capacity to manage malaria
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
