    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

    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

    Objective and subjective assessment of digestion after ingestion of an iced dessert in healthy volunteers

    The aim of our study is to assess, with objective measures, the impact on digestion of a coffee-flavoured iced dessert ingested at the end of a standardized meal; moreover, a subjective assessment, using a specific questionnaire, was carried out in order to compare objective and subjective data. Ten healthy male volunteers, after ENT and psychological assessment, underwent two scintigraphic evaluations (standardized meal without and with coffee-flavoured iced dessert) and, after the meal, filled in a specific questionnaire named dynamic digestibility questionnaire. In our sample the ingestion of the coffee-flavoured iced dessert seemed to improve the digestibility of a standardized meal: the difference between the curves of gastric emptying without and with iced dessert is statistically significant. These data are strongly confirmed by subjective assessment: the dynamic digestibility questionnaire (DDQ) showed a higher digestibility of a standardized meal with the coffee-flavoured iced dessert in comparison to a normal meal. The current study represents a preliminary report on this topic with a small sample of healthy volunteers: further studies on larger population are requested in order to confirm all the encouraging results herein discusse

    Digestibility, palatability and emotional status after ingestion of an iced dessert: analysis of subjective responses in 100 healthy volunteers.

    Food choices are influenced by many factors, perhaps the most important being availability. However, the desire to consume one item over another may be viewed as an outcome of sensory hedonic likes, situation and current internal state. In a previous preliminary report, an improvement of joy and mood, associated with good data of digestibility and palatability, was observed in a group of 30 healthy female subjects who consumed a coffee-flavoured iced dessert immediately after a standardized meal. The aim of this study is to confirm the results previously obtained in a smaller population and to investigate whether any differences between male and female subjects could be observed concerning the digestive process and emotional status. One hundred volunteers, after ENT and psychological assessment, were asked to fill out a Psycho-Emotional Questionnaire to assess their basal emotional pattern before the consumption of an iced coffee-flavoured dessert after a standard meal. After the meal they completed an Organoleptic-Sensory questionnaire, a Dynamic Digestibility questionnaire and again the Psycho-Emotional Questionnaire. In our study, most of the 100 subjects found the tested coffee-flavoured iced dessert pleasant according to the Organoleptic-Sensorial Questionnaire (OSQ), in terms of taste, aspect, texture and smell; moreover, the Dynamic Digestibility Questionnaire (DDQ) showed a good digestive experience in 71 subjects. According to the Psycho-Emotional Questionnaire (PEQ), an improvement of joy, activation and mood, associated with good data of digestibility and palatability was recorded. All these observations are statistically significant and the results seem to show a positive correlation between pleasure in eating such a product and emotional status. No statistically significant differences were recorded between male and female subjects

    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
