Effectiveness of Field Visit in Community Medicine: A Randomized Control Trial
No full textBackground: The community medicine is a major subject in un- dergraduate curriculum in India. Though much is said about methods and technologies to improve teaching in the subject, the scientific proof of field visits being better than class room teaching for understanding concepts like primary health care lacks. A ran- domized controlled trial, can give better idea of effectiveness of the intervention i.e. actual field visit to the heart of primary health care services-primary health center.
Method: Double- blind block randomization trial with two arm parallel design. The intervention group and control group were subjected to a semi-structured questionnaire following interven- tion. Logistic regression for Odds ratio adjusted for sex and at- tendance calculated.
Results: Crude and adjusted odds ratio highly significant in fa- vour of intervention group. However, on sub component analysis for adjusted odds ratio for both variables, data management at PHC was having odds ratio <1. Adjusted odds were significantly high, specially for functions of medical officer and staffing pattern of PHC.
Conclusion: The randomization clearly suggests that field visit of primary health center helps students understand and realize con- cepts of primary health care better than classroom teaching. Repli- cation of such studies with larger sample size may help
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
A Prevalence Study of Iodine Deficiency Disorder in Children of Primary Schools in Gandhinagar District
No full textObjective: To assess the magnitude of IDD in Gandhinagar region and also assess the salt consumption patterns in the region.
Study Design: It is a Cross-sectional study conducted in primary schools of both urban and rural areas. Clinical examination of study population for goiter, laboratory assessment of casual urine sample for urinary iodine and estimation of Iodine in salt samples were done. School children in the age group of 6-12 years were selected for study using WHO 30-cluster methodology. During the school survey, 10 salt samples were collected from the students (preferably from all age group) and tested on the spot with UNICEF kit. Iodine concentration recorded as 0, 15. Fourteen Samples of Urine were obtained from students for Iodine estimation from each school.
Results: An overall goiter prevalence of 7.75% was observed in the district. Females had a prevalence of 7.68% and males 7.82%. 78.57 percent of subjects had urinary iodine excretion >100mcg/l with 21.43% having moderate -mild iodine deficiency. In Gandhinagar region, 93.2% of households consume powdered salt with 90.5% powdered salt samples having an iodine content of greater than 15 ppm.
Conclusion: Iodine deficiency remains a public health problem in kalol and dehgam taluka and proper administrative action to enhance universal iodinization is recommended
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
