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
A cross-sectional study on public knowledge and awareness of antibiotic use and antimicrobial resistance in Mangalore, India
Get PDFBackground: Antimicrobial resistance (AMR) is a growing global public health issue that requires immediate attention. Aim: This study aimed to assess the knowledge, attitudes, and practices related to antibiotics and AMR among the general population in Mangalore, India. Materials and Method: A cross-sectional survey was conducted among 250 participants, out of which 220 were used for reporting results, and 30 were excluded due to incompleteness. Result: The results showed that many participants had limited knowledge regarding the proper use of antibiotics, and a significant number tended to misuse them. 74.3% of participants did not complete the full course of antibiotics, and 51.82% used leftover antibiotics for the same cases. On the other hand, the majority of participants recognized the importance of checking the expiry date of antibiotics 80.91% said yes and 66.36% agreed that unnecessary use of antibiotics causes bacterial resistance. Conclusion: This study highlights the gaps in public knowledge and practices related to antibiotics and AMR in Mangalore, India. It underscores the need for more public education and awareness campaigns to prevent the misuse and overuse of antibiotics, and to prevent the emergence and spread of antimicrobial resistance. A multi-faceted approach that involves healthcare providers, policymakers, and the public is necessary to tackle this global public health challenge.
 
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
COMPARISON OF ANTIBACTERIAL ACTIVITY OF LEAVES EXTRACTS OF TECTONA GRANDIS, MANGIFERA INDICA, AND ANACARDIUM OCCIDENTALE
Get PDFObjective: World Health Organization estimated that 80% of people worldwide rely upon herbal medicines for some aspect of their primary healthcare. For most of the herbs, the specific ingredient that causes therapeutic effect is not known. Bacterial infections are one of the prominent causes of health problems, physical disabilities and mortalities around the world. Plants have been used in medicine as antimicrobial agents since ancient times could provide a promising solution for drug-resistant species. The present study involves comparison of the antibacterial activity of ethanolic extract leaves of Tectona grandis (teak), Mangifera indica (mango), and, Anacardium Occidentale (cashew).Methods: Authentication, morphological studies and phytochemical screening studies on alcoholic extracts of leaves were carried out. Antibacterial activity was carried out by using different concentrations of extracts on bacterial strains of Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa by using agar well diffusion method and results were compared.Results: Preliminary phytochemical screening of extracts revealed the presence of alkaloids, glycosides, saponins, resins, tannins and flavonoids. Antibacterial activity was observed in the concentration range of 25-100 mg/ml for all the extracts except T. grandis leaves. They are effective at 50-100 mg/ml concentration.Conclusion: Comparison of results reveals that leaves of T. Grandis have less antibacterial activity compared to M. Indica and A. Occidantale extracts.Keywords: Teak, Mango, Cashew Leaves Extracts, Phytochemical Screening, Antibacterial activit
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
