    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    SUCCESSFUL MANAGEMENT OF RADIAL NERVE PARALYSIS IN A 2 YEAR-OLD MONGREL

    A 2 year-old mongrel was presented to the Veterinary teaching hospital, University of Ibadan with knuckling of the right forelimb. The client gave history of automobile accident. The animal was clinically evaluated with rectal temperature 38oC, heart rate 80 beats/minutes and respiratory rate of 16 The animal resented the limb being touched. The case was managed therapeutically with Neurobion® which is a combination of vitamins B1,B6 and B12 , Non-steroidal anti-inflammatory drug (NSAID) which was given by oral administration. The right fore-limb was placed in plaster cast (POP) to discourage the use of the limb so as to avoid further use of the limb while cage rest was advised. The type of nerve injury encountered here falls under the classification of neuropraxia. Here, it presents as minor contusions or compression of the peripheral nerve with a temporary interruption in the transmission of electrical impulses that will typically resolve by 3 to 6 weeks. Finally, the use of plaster cast was to discourage active use of the limb and an anti- inflammatory agent helped to quickly restore the use of the limb

    Effects of aloe vera gel application on epidermal wound healing in the domestic rabbit

    Background: A wound is a breakdown in the protective function of the skin or loss of continuity of epithelium, with or without loss of underlying connective tissues, muscles, nerves, bones following injury to the skin, surgery, a blow, cut, chemicals, heat, cold, friction, shear force, pressure or diseases such as leg ulcers or carcinomas. A study was undertaken to determine the healing properties of Aloe vera gel on epidermal wounds in rabbits.Methods: Twelve adult rabbits were divided into two groups randomly of six each representing the treatment and control respectively. A pair of wounds measuring 2cm x 2cm each was created on the back of each rabbit lateral to the spinal cord. The wounds were treated with homogenized Aloe vera gel while the wounds on control group were treated with normal saline. Wound contraction was measured on days 5, 9 and 12 representing the inflammatory, proliferative and maturation phases of wound healing respectively. Blood samples were collected on days 0, 3, 6, 9 and 12 for analysis.Results: Animals treated with Aloe vera gel had significantly (p<0.05) faster rates of healing with shorter days of scab fall off than the control and showed significant (P<0.05) changes in the packed cell volume, mean corpuscular volume, lymphocyte and neutrophil counts.Conclusions: The study concluded that Aloe vera was effective in treating epidermal wounds in rabbits over the control. An improvement occured in haematological profile of the experimental animals and these findings will go a long way in expanding the horizon of clinical application of this plant in solving wound healing problems in both humans and other animal species

    Variations on the Author

    “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 link
    We 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 link
    We 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 text
    We 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
