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
The medical geography of cannabinoid botanicals in Washington State: Access, delivery, and distress
No full textThough rendered dormant by a post-1937 Cannabis sativa L. prohibition, the emerging field of cannabinoid medicine is growing in the United States as ever greater numbers of physicians become educated about the physiologic importance of the endogenous cannabinoid system and about the wide safety margins and broad clinical efficacies of cannabinoid drugs, available in both purely botanical and purely chemical varieties and useful for managing pain and other conditions in the growing chronically and critically ill patient population. Research presented here is focused on medical access and delivery of cannabinoid botanicals in Washington State and seeks to map the geography of this developing cannabinoid medical care system by taking medical geographic “snapshots” of two purposefully chosen locations: a rural clinic site in Washington State where patients currently access cannabinoid botanicals for medical use in the treatment of chronic pain syndromes with acceptable safety under medical supervision and another site where qualifying patients are delivered environmentally-culled cannabinoid botanicals. At the former site, retrospective chart reviews were conducted with 139 patients with chronic pain, and at the latter site, a convenience sample of 37 qualifying patients delivered a monoclonal lot of cannabinoid botanical medicine were prospectively studied using standard and tailored survey instruments. A political ecology of disease approach was employed to rationalize and depathologize patients' mental distress at potentially facing possession-related legal problems due to their consumption of the still-contraband biota. Results provide quantitative and qualitative insight into the frail health status in both samples of qualifying patients and give a grounded understanding of the lengths that patients and care providers go, despite multiple hurdles, to access and deliver treatment with cannabinoid botanicals that relieves patients' diverse symptoms and improves their health-related quality-of-life
