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
Impact Of Eating Disorder On Nutritional Status And Dietary Pattern- A Cross-Sectional Study On Adolescent Girls Of North 24 Parganas District Of West Bengal
Get PDFIntroduction: Adolescent girls are very much concern about body image, follow disordered eating habits. In 21st century one of the public health problems is eating disorder (ED), characterized by obsession with body image, food habit. Food restriction, selective eating, meal skipping (MS), excessive exercise, laxative misuse are some common behaviors of adolescent girls even of developing countries to make perfect physical posture. Objective of the study is to find out prevalence of ED and MS among adolescent girls of North 24 Parganas district and to determine their association and significance on Body mass index (BMI).
Method: 385 healthy adolescent girls were selected randomly from different schools and colleges of the district according to convenience. ED was detected using Eating Disorder Examination Questionnaire (EDE-Q). MS habit, frequency in a week and timing were asked individually. Statistical tests were performed in SPSS (IBM, version 16) for analysis of data.
Result: 11.95% and 15.84% participants respectively had ED and MS tendency. Statistically significant difference in BMI was found between ED and control (p<0.01) and MS and non-MS (p<0.05) groups. There was significant association (p<0.01) between ED & MS. Weight concern had significant positive correlation with BMI (p<0.01).
Conclusion: BMI was higher among ED and MS participants than others. Excessive weight concern and inappropriate practices to lose weight adversely affect weight and food habit and make psychologically distressed. Meal skipping may cause nutritional deficiencies during the crucial growing period of adolescence age
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
Assessment Of Nutritional Status And Eating Behavior Among Undergraduate Nursing Female Students Of Birbhum District Of West Bengal: A Cross-Sectional Pilot Study
Get PDFOne of the most common psychological and lifestyle disorders of adolescent girls of 21st century is eating disorder(ED) especially among students of heath background; characterized by preoccupation with food, body size and shape. Food restriction, overeating both are categorized under ED. The objective of the study is to determine the prevalence of ED among female nursing students of Birbhum and its association with Body mass index(BMI), anemia and menstruation frequency. The pilot study was done on 100 students of a private nursing college of 19-20 years with self-reported Eating Disorder Examination Questionnaire(EDE-Q). Participants were selected by random sampling method. Height, weight and skin fold measurements were taken. Clinical signs of anemia were checked. Pearson’s Correlation between ED and BMI, body fat percentage and Chi-square test for association of ED with anemia and menstruation frequency were done. 11% students were detected to have ED. Among them, 4 persons were overweight and 5 were obese. 24% population were detected with mild anemia among them 5 girls has ED. 3% students have both ED and irregular menstruation and only 4% students of the rest have irregular menstruation. Weight and shape concern of ED population was also found to be positively correlated. Overweight and irregular menstruations are associated with ED that should be taken into consideration during any ED prevention programme
