    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

    Balancing up, Down, and in: NGO Perspectives During Nepal’s Covid-19 Crisis

    This study examines how different forms of accountability relationships affected NGO operational resilience during Nepal’s Covid-19 crisis. Drawing on stakeholder and institutional theory, the research investigates three key questions: How do federal government restrictions impact NGO operational resilience? What role does local government satisfaction play in organizational resilience? And how do concerns about beneficiary wellbeing relate to operational challenges? Analysis of survey data from 274 NGOs in Nepal, collected during peak pandemic restrictions, reveals three key findings. First, federal government restrictions significantly impaired NGO operations, with regulatory constraints directly impacting organizational effectiveness. Second, satisfaction with local government response showed no significant relationship with operational concerns. Third, organizations more concerned about their beneficiaries’ welfare experienced greater operational challenges. These findings demonstrate how different forms of accountability pressure create varying levels of organizational strain during crises, providing concrete evidence for “Multiple Accountabilities Disorder,” and highlighting the need to differentiate between federal and local government relationships in accountability frameworks. These findings have significant implications for NGO management practices and policy approaches to civil society regulation during crises

    Long term effect of fertilizer application on cadmium uptake on oat (Avena sativa) plant

    Phosphate fertilizers contain varying amounts of Cd and other heavy metals as contaminants from phosphate rock (PR). Periodic applications of these fertilizers resulted in measurable accumulations of Cd in soils and in harvested crops. A long term field study for fourteen cropping seasons (1992-2006) was conducted on an experimental plot located at the Norwegian University of Life Sciences (Ås, Norway) to evaluate the effect of application of cadmium enriched phosphate fertilizer on soil solution dynamics of cadmium and Cd accumulation in Oat (Avena sativa). Treatments consisted of three NPK fertilizer sources containing 1, 90, 381 mg Cd kg-1 P and supplying 0.03, 2.7, 11.43 g Cd ha-1yr-1. Surface soil samples (0-20 cm) were collected after harvesting of plant in 1992, 1995, and 2006. Plant samples were analyzed for 1992, 1995, 1997, 2002 and 2006. Soil samples were analyzed for total and extractable Cd, pH, dissolve organic carbon (DOC) and PO4 3-. Analysis of plant samples was done for total concentration of Cd and plant uptake of Cd was calculated. A general trend of decrease in plant Cd with increased soil pH was observed throughout the experiment period except 1992 where plant Cd concentration did not significantly change with soil pH. Increasing the addition of Cd input through fertilizers only increased the Cd concentration in soil, but the Cd concentration in oat grain was not affected significantly. NH4NO3 - extractable Cd in the soil increased with increasing rate of Cd through different sources but the concentration of extractable Cd in the soil decreased with increased pH throughout the experimental period except in 1995 where soil pH did not show any consistent effect on extractable Cd. Plant Cd did not show any significant correlation with extractable Cd in soil. Hence the concentration of Cd in oat grain was not significantly affected by Cd input through fertilizers

    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
