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
Development of Evidence-Based Practice Guidelines for Utilizing Erector Spinae Plane Blockade for Patients Undergoing Cardiac Surgery
Full text linkIn the United States, the aging population and high rates of cardiovascular disease leads to increased cardiothoracic surgeries. Analgesia for cardiac surgeries often involves high-dose opioids. However, with an ever-increasing opioid epidemic and adverse effects on the postoperative healing process, recent literature seeks to decrease opioid consumption by utilizing alternative methods of analgesia. The American Association of Nurse Anesthetists recommends the use of regional anesthesia techniques to reduce the incidence of undertreated postoperative pain that can occur from opioid-sparing methods of analgesia. This project aims to create an evidence-based analgesia guideline for adult patients undergoing cardiac surgery. Interventions will include an erector spinae plane block and an opioid-sparing postoperative guideline; evidence shows that erector spinae plane blocks decrease postoperative opioid consumption and improve postoperative outcomes, specifically decreased postoperative mechanical ventilation time. The Johns Hopkins Evidence-Based Practice Guideline Model for Nurses and Healthcare Professionals will guide this process

Abstract
According to the CDC (2020), heart failure occurs when the heart cannot pump enough blood and oxygen to support other organs in your body. Heart failure is an epidemic disease affecting 1-2% of the population worldwide (Schwinger, 2020). It is one of the leading causes of morbidity and mortality worldwide with an estimated 6.5 million adults with heart failure in the United States (Lo et al., 2021). Medical advances have increased the survival of those diagnosed with heart failure (Lerman, et al., 2019a) leading to an increased prevalence of those with cardiovascular risk factors undergoing non-cardiac surgeries (Smilowitz et. al., 2018). Patients with existing heart failure undergoing surgery are at an increased risk for major cardiovascular complications such as death, myocardial infarctions, and stroke (Smilowitz, et al., 2018). The attached poster explores defining heart failure, the pathophysiology, signs and symptoms, and treatment of heart failure. Due to the increased risks of morbidity and mortality associated with patients with heart failure in the perioperative period, nursing and perioperative considerations are also discussed.

Variations on the Author
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
