Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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

How Emerging Concerns about Field Sobriety Testing May Help Us Understand the Abuse Potential of Alcohol
No full textAmericans are struggling with substance use disorders more than ever before. For alcohol use, comparisons of nationally representative survey data from 2001 to 2012 indicated that U.S. adults have increased both risky drinking and rates of alcohol use disorders (Grant et al., 2017). These increases in drinking have paralleled the increases in opioid-related deaths that have become a public health crisis (Brady et al., 2016). The purpose of this talk is to highlight how results from Dr. Marczinski’s lab in the Department of Psychological Science can help us better understand why people abuse alcohol and other drugs of abuse.
The human and animal literature demonstrates that the acute administration of alcohol reliably impairs the ability to balance without swaying when standing (Zoethout et al., 2012). Since alcohol-induced increases in body sway contribute to feelings of instability when walking, motor impairments that are experienced after drinking alcohol appear to provide social drinkers with feedback that may contribute to their perceptions of their impairment. For example, the results from a field study revealed that subjective intoxication ratings given by bar patrons were better predicted by motor impairment and not by cognitive impairment, after controlling for current breath alcohol concentration (Celio et al., 2014). In essence, motor impairment (or lack thereof) may indicate intoxication levels. An individual feeling imbalanced while standing or walking may be more likely to self-assess impairment. Also, external assessments of alcohol intoxication heavily emphasize observable motor impairment. The standardized field sobriety test used by police requires an individual to stand on one leg or walk a straight line to detect possible alcohol impairment. A bartender may assess that a patron should no longer be served alcohol after observing the inability to stand up without assistance. Given that we (individually and as a society) rely so heavily on motor impairment to detect intoxication, it is interesting that little is known about the impact of stimulant drugs on prototypical alcohol-induced gross motor impairment. This talk describes findings from two separate 2018 publications from Dr. Marczinski’s lab on the combined effects of alcohol and energy drinks on body sway and other objective and subjective measures relevant to understanding impaired driving. By finding some flaws with the standardized field sobriety tests, she will also highlight how the data actually give us greater understanding about the abuse potential of alcohol. Given that consumers of alcohol mixed with energy drinks (or other stimulant drugs) are more likely to drive while impaired and receive a diagnosis of a substance use disorder when compared to alcohol alone consumers, studying drugs in combination rather than in isolation may be key in improving our understanding of the development of substance use disorders.

Variations on the Author
Get PDF“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
Get PDFWe 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
Get PDFWe 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 textWe 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
