    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

    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

    Examining the Role of Executive Functions on the Intention-Behavior Gap of Alcohol Harm Reduction Strategy Use

    Alcohol harm reduction strategies are health behaviors that aim to minimize the likelihood or severity of consequences associated with alcohol use. Despite the demonstrated usefulness of harm reduction strategies, there is variability in who and when the strategies are used, leading to the question “if they work, why not use them all the time?” One potential explanation is a discrepancy between the intention to drink safely and actually drinking safely, termed the intention-behavior gap. It is unclear to what extent college drinkers plan on engaging in safe drinking behaviors but fail to follow through. It is plausible some drinkers have the intention to drink safely but lack the ability to effectively initiate and execute the harm reduction behaviors. As such, executive functions (EF: cognitive abilities associated with goal-directed behavior) may be one mechanism that helps explain the gap between safe drinking intentions and behavior. Using ecological momentary assessment, the current study explored the extent to which an intention-behavior gap in harm reduction strategy use exists among college student drinkers (n=77), and investigated how potential individual differences in EF (i.e., working memory, set-shifting, and inhibition) were associated with translating intentions of drinking safely into action. Daily monitoring assessments contained brief measures of intention to use harm reduction strategies, actual strategy use, and alcohol-related behaviors, and were assessed daily for twenty-one days. Multilevel model analyses revealed that although intention to use strategies predicted actual strategy use, measures of EF did not significantly moderate the relationship. Efforts to increase intentions to use alcohol harm reduction strategies should be included in alcohol use prevention and intervention programs for all drinkers, regardless of differences in EF ability

    Motivation Matters: The Interaction of Approach and Avoidance Alcohol Motivation and Self-Control Demands in College Drinkers

    Failure in self-control has long been identified as a risk factor for problematic alcohol use among college students, as individuals who are less equipped or less able to regulate their thoughts, emotions, and behaviors use alcohol more frequently and are at greater risk for binge drinking. Recent findings suggest self-control depletion and motivation interact to determine performance on subsequent tasks that require self-control. The purpose of the present study was to investigate the ways self-control exertion and desires to use alcohol (approach inclinations) and desires to avoid using alcohol (avoidance inclinations) impact subsequent alcohol use behavior. Using ecological momentary assessment, the interaction of self-control exertion and alcohol motivation in the prediction of alcohol use behaviors was assessed in a sample of college drinkers. Daily monitoring assessments contained brief measures of alcohol-related behaviors, alcohol motivation, and self-control exertion and were administered five times daily for fourteen days. Results indicated that although self-control exertion interacted with alcohol motivation to predict drinking (controlling for drinking history, affect, and day of week), the relationship was not in the expected direction; higher self-control exertion among those high on both approach and avoidance motivation was associated was fewer number of drinks at the next measurement occasion. Findings highlight the need for consideration of the unique effects of both alcohol use motivation and self-control demand in the prediction of alcohol consumption, and draw attention to the need for further investigation into the complex interplay of these processes in daily life
