    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    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

    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

    EFFECT OF OIL AND AGRICULTURE ON ECONOMIC GROWTH IN NIGERIA

    No full text
    The study examines the interaction and feedback mechanism between agricultural and oil sectors with output in Nigeria from 1981 to 2012, using vector auto regression (VAR) methodology. Output response to OIL revenue innovation was only additive in the shortest. Output response to agriculture output exhibited positive effect of economic development through investing in the agricultural sector even from the gains from the oil sector in as oil shock showed positive response in the agricultural sector in Nigeria. Conclusively, the three economic variables are vital economic mix for economic development in Nigeria and policies and planning be optimised for economic progress

    Education and Health as Siamese Twins in Nigeria’s Economic Development

    The study examined the effect of education and health as Siamese twins’ indicators of human capital (HC) in the economic development process in Nigeria. The imperativeness of HC in Nigeria becomes out-sound when such uprising like education standard, quality of graduates, tertiary institution ranking, standard of medical facilities, rising diseases/infections, rate of infant mortality, low life expectancy and access to medical service per thousand etc are considered. This study therefore seeks to question the efforts of government in contributing to transform these sectors and seek to know which sector impact more on economic growth in Nigeria. Annual data on education, health and economic output with the dynamics of both descriptive and econometric methods from 1981-2010 were used. The descriptive analysis showed that health and education effort by the government were inconsistent with expectation until the nations’ democratic dispensation where a progressive efforts were evident in HC development. With innovation in the endogenous growth model, the OLS regression showed that the education growth contributes significantly to on economic growth rate in Nigeria within the study period while the health growth rate negatively relating to economic growth rate though at a non-significant level in Nigeria economy. Conclusively, both education and health are germane to economic growth but education impacted more in Nigeria and no effort exerted will be too much. The government and private sector are therefore implored to invest in education and health-related areas for healthy economic transformation in Nigeria.

    koamabayili/VECTRON-author-checklist: VECTRON author checklist

    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
