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
Oral bacterial flora of Indian cobra (Naja naja) and their antibiotic susceptibilities
No full textObjectives: The objective of the present work was to examine the bacterial flora associated with the oral cavity of Indian cobra and to study their antibiogram. Methods: Oral swabs, collected from six healthy (4 males and 2 females) adult cobra, were subjected to microbiological examination through differential media. A total of 74 isolates which demonstrated noticeable colony characters were studied with different biochemical tests. The strains that showed distinctive colonies, morphology and biochemical parameters were additionally subjected to phylogenetic characterization using 16S rRNA gene sequences. Further, the isolates were subjected to antimicrobial susceptibility testing using ICOSA-20-plus and ICOSA-20-minus. Results: Microscopic examination of the oral cavity of Indian cobra revealed the dominance of Gram-negative bacteria over Gram-positive. The oral microflora constituted of bacteria such as Salmonella sp. (S. typhi, S. paratyphi A); Pseudomonas sp. (P. aeruginosa, P. fluorescence); Proteus sp. (P. mirabilis, P. penneri, P. vulgaris); E. coli; Morganella sp.; Citrobacter sp. (C. diversus, C. freundii); Aeromonas sp. (A. hydrophila, A. salmonicida); Enterobacter sp. (E. aerogens); Acinetobacter sp. (A. baumannii); Neisseria sp.; Serratia sp.; Bacillus sp. (B. cereus, B. megatarium, B. atrophaeus and B. weihenstephanensis); Enterococcus sp. (E. faecalis, E. faecium); Staphylococcus sp. (S. aureus, S. epidermidis); Alcaligenes sp.; Chryseobacterium sp. and Micrococcus sp. Most of the isolates were resistant towards antibiotics such as Penicillin, Cefpodoxime, Amoxyclav, Co-Trimoxazole, Ticarcillin, Erythromycin and Nalidixic acid while sensitive towards Ciprofloxacin, Gentamicin, Ofloxacin, Sparfloxacin, Tobromycin, Ceftriaxone, Tetracycline, Novobiocin and Imipenem. Conclusions: The secondary complications of the snake bite victims should be managed with appropriate antibiotics after proper examination of the bacterial flora from the wound sites
Antimicrobial efficacy of potential plants used in the indigenous preparation of traditional rice beverage “Handia”
No full textThe context andpurpose of the study: To explore the available plants usedfor starter preparation of Handia, their ethnomedicinal uses and to screenphytochemical constituents for antibacterial activity against enteric pathogens.The main findings:Semi-structured interview was carried out with 24 informants (mean age 46,male) from 24 locations. Qualitative phytochemicalanalysis, agar cup assay, micro-dilution method for MIC and MBC were followed tostudy antibacterial properties against eight enteric pathogens. Ethanol extracts of the plants contain abundant alkaloids,flavonoids, carbohydrate, protein and amino acids, saponins, tannin and phenolic compounds. With theexception of Aspargus racemosus (root), Cissampelos pareira (leaf), Dioscorea sp. (tuber), Rauwolfia serpentina (leaf) extracts, all otherplants exhibited antibacterial activity by agar cup method. The zone ofinhibition was found maximum against Staphylococcusaureus followed by Shigella sonnei and S. flexneri. The MIC result ranged from 125 to 1000 µg/ml (w/v) with the lowestagainst S. aureus (125, 156, 250µg/ml) followed by S. sonnei (156,250, 312, 500, 625 µg/ml). MBC test validate that in between 1000-2500 µg/ml(w/v) concentrations, most of test bacteria were killed due to broad spectrumactivity. Brief summary andpotential implications: The study establishes thatthe traditional knowledge of Handia preparation using different plant parts will be a useful leadfor phytochemist and pharmacologists for further study
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
