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
Lower Urinary Tract Symptoms Associated with Parkinson's Disease
Parkinson’s Disease (PD) is a neurodegenerative disease associated with a loss of dopaminergic neurons in the basal ganglia, located in the midbrain. PD patients are typically over the age of 50 because dopamine production slows due to continuous degeneration of dopamine cells as age progresses. Individuals with the disease typically exhibit both motor and non-motor symptoms, including some autonomic issues. Motor symptoms occur early in the disease, and are described as tremors, muscle rigidity and slowness of movement. A common autonomic issue is bladder dysfunction, typically caused by detrusor overactivity, leading to nocturia, increased urgency and increased frequency.
This project aims to recreate these urinary symptoms in laboratory rats by injecting 6-OHDA into the periaqueductal grey area of the midbrain and the lumbosacral spinal cord. The purpose of the injection is to prove that the loss of dopaminergic neurons are in fact the cause of these bladder issues. The current protocol begins with a 6-OHDA injection in the intended area (either into the midbrain or the CSF in the lumbosacral spinal cord) and requires the periodic monitoring of micturition patterns in awake rats with the use of diuresis chambers. After this period of observation, the animals are anesthetized for a terminal procedure that examines and records bladder-sphincter reflexes. Lastly, immunohistochemistry is used to test for tyrosine hydroxylase (TH), a dopamine marker, once the brain and spinal cord are removed. It is anticipated that these manipulations will result in changes in LUT function similar to those that occur in PD.SUNY BrockportSUNY Undergraduate Research Conferenc
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

Postoperative Discharge Opioid Education including Narcan Kit Access to Prevent Overdose: A Quality Improvement Project
Significance and Background: Opioid related overdoses are considered a public health epidemic and emergency in recent years within the United States. With a staggering number of opioid related deaths which have continued to rise, steps have been taken to decrease risk within local communities through programs including personalized patient education during provider visits, the dispensing of Naloxone with opioid prescriptions and encouraging the use of alternative pain management strategies. Most recently, New York State passed a recommendation encouraging all healthcare providers to prescribe Naloxone with the first opioid prescription of each year for patients deemed high risk for overdose. A policy to encourage appropriate patient education with Naloxone prescriptions was needed within a local community hospital setting. Evidence supported the use of an opioid safety toolkit education within the postoperative population being discharged on opioid pain medications.
Purpose: Deliver opioid safety toolkit education with Naloxone prescription to postoperative patients being discharged with opioid pain medications. Compare patient confidence in Naloxone use within the community post education.
Methods: Plan-Do-Study-Act. Plan: The presence of an opioid safety toolkit education within the outpatient pharmacy of the project hospital which is readily given with Naloxone to postoperative patients going home with opioid prescriptions. Do: Outpatient pharmacy staff introduced the opioid safety toolkit into their normal workflow, including education regarding Naloxone use, alternatives to opioids, proper use, side effects and overdose red flags. Study: Data was gathered on patient self-reported confidence in Naloxone use within the local community post-discharge. Act: Present data to organizational stakeholders.
Outcome: Over the ten-week data collection period which was divided into five-week trials, there were a total of 155 opioid prescriptions and 79 Naloxone co-prescriptions (a co-prescription rate of 50.96%). In the second and more successful trial, there were 95 opioid prescriptions and 68 Naloxone co-prescriptions (a co-prescription rate of 71.6%). All patients, with the exception of two reported high confidence in Naloxone use post-discharge in an emergency situation (97.4% reported confidence). Only two patients declined the prescription due to high copayment costs, but a copayment assistance program was adopted from a state-funded resource to address and eliminate this burden (97.5% accepted the co-prescribed Naloxone). Naloxone prescriptions increased substantially during this period, and education was provided to every patient that was given a Naloxone prescription.
Discussion: The implementation of the opioid safety toolkit education program increased patient confidence in Naloxone use post-discharge within the community setting and increased Naloxone prescriptions within the project hospital. Education focused on providing patients with practical knowledge on Naloxone as well as information regarding proper opioid use, side effects to be aware of and signs of overdose which may otherwise be overlooked
koamabayili/VECTRON-author-checklist: VECTRON author checklist
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
