Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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 Case Study on Ayurvedic management of Mutrashmari (Urolithiasis)
Full text linkBackground: Mutrashmari is disease classified as Asthamahagada which means "difficult to cure." It is Kapha Pradhana Tridoshaja Vyadhi. Due to resemblance in clinical manifestations, Mutrashmari is compared to urolithiasis. Urolithiasis, a pathological condition of the urinary system where aggregation of urinary crystalloids takes place anywhere in the urinary tract, i.e., from the kidney to urinary bladder showing male predominance (Male: female = 3:1) and currently becoming a medico‑surgical and economical challenge for entire health‑care systems. Objectives: The aim of this study was to evaluate the efficacy of Viddhakarma and Shamana Chikitsa in Mutrashmari (Urolithiasis). Materials and Methods: It is a single case study. A 52 years old male patient who was clinically diagnosed case of Urolithiasis before 3 years visited to OPD with complaints of Vrikka Parshava Shoola (Pain in bilateral kidney and b/l flanks region) which was radiating from loin to groin region in late night usually, Mutrakriccha (difficulty in maturation) and Mutradaha (Burning micturition) from last 2 months. The patient was treated with total 4 sittings of Viddhakarma were given at the lateral border of the thumb of the bilateral legs on same day of every week along with Shamana Chikitsa. Results: The patient was showed highly significant results before and after the completion of treatment. All sign and symptoms of patient resolved and there was no trace of calculi in the both kidneys, according to the USG report after 1 month. Conclusion: Highly significant relief in symptoms was seen in patient after 1 month of Ayurvedic treatment
Studies on genesis of Prameha from Amajirna w.s.r. to biochemical parameters
Full text linkBackground: In classical text it had been highlighted that Amajirna is root cause to produce Prameha. Musta is drug which combat Amajirna and it also effective to cure Prameha. So, this gives reasons for need of the present study and also reason for selection of topic. Aim: To evaluate the pathogenesis of Prameha from Amajirna and the efficacy of Musta (Cyperous rotundus) in both Amajirna and Prameha. Material and Methods: This study is an open label, randomized, interventional, comparative, prospective, controlled clinical trial. In the present study the patient of Prameha were enrolled following the subjective criteria of Prameha. A total of 60 patients of Prameha were selected from the OPD and IPD of Shyamadas Vaidya Shastra Pith Hospital, Kolkata, West Bengal, and randomly allocated with a computerized randomization method into two groups. Those selected patients were subjected for a confirmatory biochemical analysis of FBS and PPBS. The prediabetic person was interrogated for Amajirna as a past history or present illness, by the subjective criteria of Amajirna. In group A (n= 30), Musta Churna was given for 90 days and in group B (n= 30), Pippali Churna was given for 90 days. Before treatment and after treatment data FBS, PPBS, HBA1C, SGOT, SGPT, serum amylase, serum lipase and alkaline phosphatase enzyme levels were recorded for statistical analysis. This record of assessment was taken at 0, 30, 60 and 90 days. Wilcoxon signed rank test; unpaired t-test were applied. Result: Both groups showed statistically significant (p<0.05) improvement in chief complaints of Prameha, Amajirna, FBS, PPBS, HBA1C, SGOT, SGPT, serum amylase, serum lipase and alkaline phosphatase. Conclusion: On percentage wise comparison, better relief was found in Group-A i.e., Musta Churna was found to be more effective in all the subjective and objective parameters than Group-B (Pippali Churna)
AN EPIDEMIOLOGICAL STUDY ON PRAMEHA (DIABETES MELLITUS) IN KOLKATA
Full text linkType 2 diabetes mellitus is one of the most leading causes of death and disability worldwide among the lifestyle disorders where dietary and lifestyle factors play a major role. Prameha is a classical metabolic disorder of tissue and cellular level. Unhealthy diet and physical inactivity are the leading causes of the lifestyle disorders; Prameha is also among them as mentioned by Acharya Charaka. A survey study was carried out to study the prevalence of Prameha patients and associated risk factors in the light of epidemiological aspect. 120 diabetic patients from OPD of Institute of Post Graduate Ayurvedic Education and Research, Kolkata, were selected randomly according to their registered address as residents of Kolkata. A survey proforma along with consent form was prepared and detailed history of each patient fulfilling the subjective criteria of Prameha and objective criteria of Diabetes Mellitus were taken. On considering data of Santarpana nidana, maximum patients were taking excess carbohydrate (90%); dairy products (82.5%); fried and fatty diet (68.33%); sweets and sugarcane preparations (79.16%); junk and fast foods (82.5%) in excessive quantity and 51.66% patient were found to be with increased BMI. Factors observed related to lifestyle are Divaswapna (60%) and Asyasukham (65%). Udvega (stress) were found in 88.33% of patients. This study revealed that prevalence of carbohydrate rich diet; dairy products; junk food and increased BMI are found dominant in diabetes patients in Kolkata. Avoidance of these faulty dietary habits and sedentary lifestyle, further progression of the diabetes along with its complications can be inhibited
