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
Assessment of Association between Thyroid Disorders and Gout
No full textBackground: Thyroid hormones (THs) play their parts in multiple events, including development, growth, metabolism, and reproduction. Recently, attentions have been paid to THs again due to the increasing prevalence of metabolic diseases, because THs boost the body energy metabolism. Hence; the present study was conducted for assessing association between thyroid disorders and gout. Subjects and Methods: A total of 50 subjects were enrolled. Complete demographic details of all the subjects were obtained. Out of 50 subjects, 25 subjects were of subclinical hypothyroidism while the remaining 25 subjects were healthy control. Complete demographic details of all the subjects were obtained. The thyroid-stimulating hormone (TSH) test was conducted in all the patients. Triiodothyronine (T3) and thyroxine (T4) hormonal tests were also carried out. The diagnosis of subclinical hypothyroidism was performed by the physician by interpreting the results of tests based on increased TSH levels based on the age and normal range of T3 and T4. Serum uric acid levels were obtained from all the patients and the results were subjected to statistical analysis. All the results were obtained and analysed by SPSS software. Results: Mean TSH levels of the subjects of the study group and control group was 9.2 mIU/L and 4.5 mIU/L. Significant results were obtained while comparing the mean TSH levels among the subjects of the study groups. However; non-significant results were obtained while comparing the mean uric acid levels among the patients of the study group and control group. Conclusion: From the above results, authors conclude that no significant correlation exist between thyroid disorders and gout. 
Assessment of Serum Lipid Profile in Patients with Hypertension
No full textBackground: Hypertension had a global burden on 26.4% of the adult population in 2000, and projections reveal a rise to 29.2 per cent by 2025. Given its high prevalence and associated risks of progression to cardio-vascular disease (CVD) and stroke, early diagnosis becomes crucial. The present study was undertaken for assessing serum lipid profile in patients with hypertensive patients. Subjects and Methods: A total of 50 patients with confirmed diagnosis of essential hypertension were enrolled. Another set of 50 age and gender matched subjects were taken as healthy controls. Complete demographic and clinical details of all the subjects were obtained. Blood samples were obtained from all the subjects and were sent to laboratory where autoanalyzer were used for assessment of serum lipid profile. All the results were recorded in Microsoft excel sheet and were analyzed by SPSS software. Results: Mean Triglycerides among the patients of the essential hypertension group and control group was 1.36 and 1.15 respectively (p- value < 0.05). Mean total cholesterol levels among the patients of the essential hypertension group and control group was 4.96 and 4.05 respectively (p- value < 0.05). Conclusion: Serum lipid profile is significantly deranged in essential hypertension patients. 
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
