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
Clinical and Electrophysiological Profile of Chronic Kidney Disease Patients Undergoing Peritoneal Dialysis at a Tertiary Care Centre of Bihar
Get PDFChronic kidney disease (CKD) is a progressive decline in renal function, which is responsible for significant morbidity and mortality. The present study was carried out to assess prevalence of peripheral neuropathy in CKD patients on PD patients with special emphasis on electrophysiological parameters and severity of peripheral neuropathy and its relation with diabetes mellitus. Methodology: During the period from November 2020 to April 2020, 50 consecutive patients diagnosed to have CKD and are on OPD at J.N.K.T. Medical College, Madhepura, Bihar, India were included in the present study. Patients with pre-existing peripheral neuropathy prior to the diagnosis of CKD were excluded from the present study. The study was approved by the Institutional Ethics Committee and written informed consent was obtained from the patients for their participation in the study. The patients were divided into two equal groups, randomly: Group 1 included 25 diabetic patients Group 2 included 25 nondiabetic patients. All cases were subjected to nerve conduction studies (NCS) using Medelec synergy and Natus machines. NCS procedure was done for both motor conductions and sensory conductions. Median nerve, ulnar nerve, common peroneal nerve, and posterior tibial nerve were assessed for motor conductions. Median nerve, ulnar nerve, and sural nerve were assessed for sensory conductions. Results: The prevalence of peripheral neuropathy among the study participants was 62% (31 out of 50) based on clinical symptoms and 80% (40 out of 50) based on electrophysiological parameters. Based on electrophysiological data, prevalence of peripheral neuropathy in CKD patients on PD with DM and without DM was 100% and 60%, respectively. Conclusion: Rationale management of diabetes in CKD patients on PD probably lowers the prevalence and severity of peripheral neuropathy
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
A study on correlation of serum uric acid level and glycemic control among patients of type II Diabetes Mellitus at a tertiary care center of Bihar
Get PDFIntroduction: Diabetes mellitus is a metabolic disorder which is characterized by hyperglycaemia and insufficiency of the secretion or the action of endogenous insulin. Although the aetiology of the disease has not been well defined, viral infections, autoimmune diseases, and environmental factors have been implicated. With this background, the present study was undertaken to find the correlation of the serum uric acid and the glycemic control in patients with type 2 Diabetes mellitus. The proxy indicator used for glycemic control here was glycated hemoglobin level (HbA1C). Methodology: The present case control study was undertaken in the Department of Physiology of J.N.K.T. Medical College, Madhepura, Bihar, India. The study period was 6 months that was from May 2020 to October 2020. Prior ethical approval was obtained from the Institutional ethics committee. The subjects who were included in this study were divided into 2 groups: Group A included 20 normal healthy individuals, in the age group 40-65 years, of either sex and without any family history of DM. Group B included 20 diagnosed patients of Type 2 Non-Insulin Dependent Diabetes mellitus (NIDDM), who were in the age group 40-65 years, of either sex, from the same population. Results: The mean age of the patients in group A was 31.8 ± 7.9 years and that of patients in group B was 33.6 ± 6.8 years. In the control group, there was a slight male predominance with 55% being male, while in the study group, female dominant with 75%. There was no statistical difference between both the groups based on gender and age. The mean FBS level of group A was 76.2 ± 8.3 mg/dl and that of group B was 144.9 ± 62.4 mg/dl, which was significantly higher than that of group A (p < 0.05). Conclusion: In conclusion, our study suggests that there is an increase in the serum uric acid levels with an increase in the HbA1C levels. This showed a positive relationship in Type 2 Diabetes mellitus
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
