    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

    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

    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

    Prevalence of Hepatitis B and Hepatitis C Viral Infections and Their Associated Factors among Diabetic Patients Visiting Debre Tabor Referral Hospital, Northwest Ethiopia, 2021: A Cross-Sectional Study

    No full text
    Background. Viral hepatitis is a global public health problem that affects millions of people each year, causing disability and death. Hepatitis B and C viruses are the most common causes of viral hepatitis and are associated with chronic liver disease, cirrhosis, and hepatocellular carcinoma. The primary site of infection for these viruses is the liver, the primary site of hormone and glucose metabolism closely linked to diabetes mellitus (DM), which is associated with increased morbidity and mortality worldwide. As a result, assessing the coexistence of viral hepatitis and DM could be important in disease management, prevention, and control measures in DM patients. Objective. The aim of our study is to assess the prevalence and associated factors of HBV and HCV among diabetes patients attending Debre Tabor Referral Hospital. Methods. An institutional-based, cross-sectional study was conducted from December 1, 2021, to February 30, 2021. A systematic sampling technique was used for selecting study participants. Serum samples were screened with a rapid test kit for hepatitis B (HBV) and hepatitis C (HCV) infections. A pretested structured questionnaire was constructed to collect the data, which were later analyzed using SPSS version 23. Inferential statistics were used to evaluate the associated risk factors for the outcome variable. A p value of <0.05 was considered statistically significant. Result. A total of 152 diabetes patients were included in this study, with 78 (51.3%) males and 74 (48.7%) females, with a mean age of 39.24 ± 17.90 years. The prevalence of HBV and HCV was 6 (3.9%) and 2 (1.3%), respectively. Most of potential risk factors such as, histories of surgical procedures, tooth extraction, hepatitis infection in the family, blood transfusion, alcohol consumption, body tattooing, and multiple sexual partners were not statistically significant for HBV and HCV infections. Conclusion. In this study, no association was obtained between sociodemographic, clinical, and behavioural factors and the prevalence of hepatitis B and C viruses. Furthermore, there is no significant association detected between HBV or potential HCV infection and DM. Despite these results, continuing professional training programs on HBV and HCV infection, including increased vaccination coverage rates for HBV, are required

    Dispelling the Myths Behind First-author Citation Counts

    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
