    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

    Feeding Rates of Black Soldier Fly (Hermetia Illucens) Fed on Palm Kernel Meal and Bovine Blood

    Slaughterhouses are economic activities that generate significant waste, including blood. Blood is a biological hazardous material due to its potency as a source of disease. Standard waste management methods for this material, involving physical and chemical treatment technologies, are considered expensive and impractical for small-scale entrepreneurs, leading to a neglect of waste management. Another possible waste management approach for blood is to use biological agents that utilize its nutrients. One candidate is the black soldier fly, known for its ability to consume various organic materials to produce high-value biomass. However, this process is highly dependent on the feed material\u27s characteristics and the feeding rate. In this study, bovine blood was mixed with fermented palm kernel meal as the feeding material for black soldier fly (Hermetia illucens) larvae. The objective of this study was to assess the effect of feeding rates of 50, 100, 200, 300, and 400 mg/larvae/day on the growth performance and survival of the larvae. The results showed that the time required for larvae to become pupae is 20-24 days. A 200 mg/larvae/day produced the best harvested weight and lowest FCR (feed conversion ratio). The highest growth rate was achieved at a dosage of 300 mg/larvae/day. At the same time, a 400 mg/larvae/day dose produced the highest length and WRI (Waste Reduction Index). On the other hand, the survival rate ranged from 77% to 91%, with 100 mg/larvae/day being the most effective. Mixing bovine blood with palm kernel meal at a feeding rate of more than 100 mg/larvae/day will allow the effective black soldier fly (H. illucens) larval composting process

    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

    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
