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
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
Impact of a Community-Developed Nutrition Fotonovela Versus a Brochure on Dietary Practice in the Dominican Republic
Get PDFBACKGROUND: Cardiovascular disease is the number one cause of mortality in the Dominican Republic, and diet is one of the main factors contributing to its development (World Health Organization, 2016; Mokdad et al., 2018). A fotonovela is similar to a comic book but uses photographs to tell a story about a health topic and has been shown to increase awareness and promote healthier practices.
OBJECTIVE: After two weeks and one month, participants experiencing the community-developed nutrition fotonovela will display more changes in dietary behavior than the participants experiencing the nutrition brochure.
METHODS: Zumbón was randomly selected from five communities surrounding Santo Domingo to develop a fotonovela about eating a balanced diet through focus groups. Haina and El Batey were the intervention groups in which the pastors presented the fotonovela to the communities while San Joaquín and Tres Brazos were control groups in which the pastors presented an existing nutrition brochure to the communities. Before the presentation, the participants completed a survey containing demographic and dietary behavior questions. To evaluate whether the fotonovela or brochure intervention significantly changed their diet, participants completed an identical survey two weeks and one month after the presentation.
RESULTS: Besides differences in gender, cooking ability, employment, and household composition, there were no other demographic differences within the brochure and fotonovela presentation communities. With a p-value of less than 0.05 being significant, people in Haina were eating starches more often two weeks after the fotonovela presentation. In San Joaquín, significantly more people ate grains daily at one month than before the brochure presentation. In the brochure presentation communities of San Joaquín and Tres Brazos, significantly more people ate no added fat at the one month survey compared to the two week survey. No other significant dietary changes were found within the brochure and fotonovela presentation communities when comparing pre- to post-presentation surveys.
CONCLUSION: Although differences in dietary changes between those receiving the brochure versus fotonovela were limited, the brochure presentation communities made more preferable changes in their diet than the fotonovela presentation communities within a one-month period. Nutrition brochures are effective in promoting a healthy diet while fotonovelas can potentially have long-term beneficial effects on diet. Future studies are recommended to distribute color copies of the fotonovela to a larger sample size and to follow participants' eating habits beyond one month
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
Using Pre-Op Rhythm Strips to Reduce Cardiac-Related OR Cancellations
Get PDFBACKGROUND: Same-day cancellations pose a significant financial burden to ambulatory surgical centers. Cardiac abnormalities comprise a small percentage of total cancellations, but these abnormalities are detected primarily once the patient is already in the OR and after standard ASA monitors are placed on the patient, which is particularly disruptive. Even so, 12-lead electrocardiograms (ECG) are not recommended as a pre-op test for low-risk surgeries and are not part of the standard vital signs required on the day of surgery. Thus, implementing a 3-lead ECG with rhythm strip analysis during pre-op on the day of surgery may allow for earlier detection of these cardiac abnormalities before the OR.
AIM STATEMENT: Between March 2021 to October 2022, all cardiac abnormalities that warrant a same-day surgical cancellation will be detected by our 3-lead ECGs prior to the patient entering the OR.
METHODOLOGY: This is an ongoing prospective quality improvement study at UT Southwestern Medical Center's University Hospital Outpatient Surgery Center. The study period is from March 15, 2021 to October 13, 2022. All patients arriving at the study site on the day of their surgery were included, irrespective of demographics or risk factors. Exclusion criteria included any patients under the age of eighteen, and those with missing or incomplete information documented. A 3-lead ECG test was performed in addition to the standard day-of-surgery vital signs (BP, pulse oximetry, heart rate, and temperature). An anesthetic pre-op evaluation, along with patient vital signs, was reviewed by anesthesiologists prior to admission into the operating room. For all cancellations, the primary reason, the scheduled date of surgery, and the scheduled service were recorded by hand. Plan-Do-Study-Act (PDSA) cycles were used to design and evaluate the success of interventions in each phase of this study.
RESULTS: Within the study period and site, a total of 254 surgical cancellations were identified with three distinct categories: patient-focused (113 cases, 44.5%), systemic/facility (46 cases, 18.1%), and medical (96 cases, 37.4%). Of the 96 cancellations due to medical reasons, 26 of those were detectable by an ECG. All 26 of these cancellations were detected from our rhythm strip analysis during pre-op; there were no cardiac cancellations in the OR.
CONCLUSIONS: Our findings suggest that the implementation of a 3-lead ECG was effective and allowed for earlier detection of cardiac abnormalities that would have not otherwise been discovered until the patient was in the OR. With respect to expenditure data specific to our study site, earlier detection allows for substantial cost savings. Limitations include the absence of data on total surgeries performed by specialty service and baseline cancellation rates prior to ECG implementation. In the next PDSA cycle, documentation of specific surgical procedures has been added to the cancellation intake template. With rates of cardiac abnormalities like atrial fibrillation rising and with the patient population for ambulatory surgeries becoming older, this study represents a feasible, low-cost intervention that addresses these trends
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
