The Effects of Acetaminophen on Aggression Using the Point Subtraction Aggression Paradigm
Full text linkAcetaminophen, the active ingredient in the popular over-the-counter analgesic Tylenol, has recently been found to have effects on psychological responses other than just reducing pain. Prior work in the laboratory has found that acetaminophen increases aggressive behavior on one laboratory measure of aggression, the Competitive Reaction Time task. The goal of this experiment was to further explore these social side effects and determine if the increase in aggressive behavior after taking acetaminophen generalizes to a different laboratory aggression paradigm, the Point Subtraction Aggression Paradigm (PSAP). The PSAP is a computer task in which participants engage in a competitive point-earning game with a fictitious opponent. Participants (N = 106) received 1000mg of acetaminophen or placebo and one hour later completed a 10-minute session of the PSAP. There was no effect of acetaminophen on aggressive responding. However, the acetaminophen group had marginally significant reductions in aggressive motivations and emotions. Participants receiving acetaminophen also accurately perceived the number of points subtracted from them by their opponent (i.e. provocations), whereas the placebo group underestimated the number. Thus, the increase in aggressive behavior seen on the CRT does not appear to generalize to the PSAP. The reductions in aggressive emotions and motivations for those in the acetaminophen condition on the PSAP suggest that drug effects may vary by the situation. This work is important in understanding the psychological side effects of a drug that is used by many people on a regular basis.A five-year embargo was granted for this item.Academic Major: Psycholog
Pancreatitis with a Normal Serum Lipase, a Rare Post-esophagogastroduodenoscopy Complication: A Case Report
Full text linkIntroduction: Pancreatitis after esophagogastroduodenoscopy (EGD) is not a common occurrence, particularly in the setting of a normal serum lipase. The lack of commonality may delay diagnosis and treatment in some patients presenting to the emergency department (ED) with abdominal pain after an otherwise uncomplicated procedure.Case Report: A patient with a history of gastroesophageal reflux disease presented to the ED with a complaint of abdominal pain and fever three days after an uncomplicated EGD. The patient was ultimately diagnosed with pancreatitis after a computed tomography showed pancreatic head inflammation, despite having a normal serum lipase. There were no other identified risk factors for pancreatitis in this case.Conclusion: This case serves to bring awareness to this potential procedural complication and the possibility of pancreatitis with a normal serum lipase

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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

Full text link“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 linkWe 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
