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
Effect of Drakshadi Lehya in Underweight Adolescent Girls Aged 10-19 Years
Get PDFAdolescence is a phase of rapid growth and development characterized by significant physical, physiological, and behavioural changes. In India, the prevalence of underweight among adolescent females aged 15 to 19 is 47%. Undernutrition can be compared to Karshya described in Ayurvedic classics. The proposed trial drug, Drakshadi Lehya, is a classical formulation mentioned in Ashtanga Hridaya under Pandu Roga Chikitsa, appears to be safe and potent in managing the condition. The study design was quasi experimental study with a sample size of 20 underweight adolescent girls, each for the study and control group aged between 10 and 19 years with a body mass index (BMI) less than 18.5kg/m2 were selected from the Outpatient Department of Swasthavritta, Govt. Ayurveda College Panchakarma Hospital, Poojappura, Thiruvananthapuram. Subjective parameters assessed were the cardinal signs and symptoms of Karshya as mentioned in the Brihathrayee. The objective parameters were body mass index, mid-arm circumference, and waist-hip ratio, which were analysed before the study (0th day), after the study (45th day), and after the follow up (75th day). The study group was instructed to take 12 grams of Drakshadi Lehya twice daily after meals for 45 days, along with dietary modifications based on their nutritional needs. The control group was given advice regarding dietary modifications only. The statistical analyses, using Friedman\u27s test and pairwise comparisons, consistently showed highly significant changes in the study group (p<0.001 in most cases) and often less significant or non-significant changes in the control group. This pattern of results strongly supports the efficacy of the intervention. After the study, the statistical interpretation suggest that Drakshadi Lehya is an effective formulation in underweight adolescent girls
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
Added Effect of Pratimarsha Nasya with Ksheerabala Taila (14 Aavartita) over Selected Yoga Techniques in Insomnia
Get PDFInsomnia is a prevalent psycho physiological sleeping disorder, included in the International Classification of Sleep Disorders-2 (ICSD-2). By definition insomnia is a difficulty in initiating or maintaining sleep, or both or the perception of a poor quality sleep. Insomnia leads to various social, interpersonal and occupational impairments. Clinical studies have proven that Yoga is effective in insomnia. Present study was to find out the added effect of Pratimarsha nasya with Ksheerabala taila (14 Aavartita) over selected Yoga techniques in relieving insomnia. As per Acharya Susrutha in Chikitsa Sthana, doing Pratimarsha nasya daily during evening hours (Sayamkala) renders Sukhanidraprabhodanam. A pre-post interventional study was performed in 40 participants both male and female, satisfying the inclusion and exclusion criteria. Out of 40 participants, 20 each were randomly allocated to Group I and Group II. In Group I, Pratimarsha nasya using Ksheerabala taila (14 Aavartita) was administered 1ml in each nostril at evening time along with the practice of selected yoga techniques during morning hours. In Group II, only selected Yoga techniques were advised. The study period was for 30 days. The pre & post changes in mean score value was assessed using Pittsburgh Sleep Quality Index (PSQI) score. The data was analyzed using unpaired t test, and was statistically significant with a p value ≤0.01. Thus the added effect of Pratimarsha nasya with Ksheerabala taila (14 Aavrtita) over selected Yoga techniques in insomnia is more effective than selected Yoga techniques alone
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
