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
Geographic Trends in the Ophthalmology Residency Match: Influence of Program and Applicant Characteristics
No full textAbstract
Introduction The ophthalmology residency match remains competitive. Several prior studies have examined various factors that contribute to a successful match into an ophthalmology residency program; however, the role of geographic location in the ophthalmology residency match process is unclear. The purpose of our study was to evaluate geographic trends in the ophthalmology residency match and to determine whether geographic trends vary based on program level factors such as program rank or funding source and/or applicant factors such as year of training, gender, and medical degree earned. Specifically, we assessed associations with residents training at the residency program affiliated with their medical school and/or within the same geographic region as their medical school, using data obtained through publicly available sources and residency program surveys.
Methods We used the American Medical Association\u27s Fellowship and Residency Electronic Interactive Database database to identify accredited ophthalmology residency programs. Residency program Web sites and email inquiries were used to collect demographic and geographic information for residents in the graduating classes of 2021 to 2023. Statistical analysis included χ2 testing and multivariate logistic regression.
Results In total, 1,378 residents were included from 110 ophthalmology residency programs and 218 medical schools. Residents who matched at the residency program affiliated with their medical school (18%) were evenly distributed among the Midwest, Northeast, South, and West regions (p = 0.2236). Residency programs in the West (31.7%) matched fewer regional medical students compared with programs in the South (61.2%), Midwest (57.4%), and Northeast (58.4%) (p \u3c 0.0001). Attending a publicly funded medical school was associated with higher odds of matching into a regional residency program (odds ratio [OR], 1.45; 95% confidence interval [CI], 1.10–1.90; p = 0.0001) and attending a privately funded medical school was associated with higher odds of matching into a top-ranked residency program (OR, 1.53, 95% CI, 1.34–1.82; p = 0.0002).
Conclusions The majority of current ophthalmology residents trained at programs in the same geographic region as their medical schools, with nearly 20% of residents training at their medical school-affiliated program. Geographic differences in match results were observed based on resident gender, medical school characteristics, and residency program region
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
Relative Importance of Applicant Characteristics in Ophthalmology Residency Interview Selection: A Survey of Program Directors
No full textAbstract
Introduction Ophthalmology residency positions remain competitive. A lack of clarity regarding which residency selection criteria are prioritized by program directors can heighten the stress associated with the match process. While surveys of program directors in several other medical specialties have been conducted to identify the most important residency selection criteria, there is limited data on selection criteria used by ophthalmology residency program directors. The purpose of our study was to survey ophthalmology residency program directors to identify the current state of interview selection decisions—the factors currently considered most important in determining whether to extend an interview invitation to residency applicants.
Methods We developed and distributed a Web-based questionnaire to all U.S. ophthalmology residency program directors. Questions evaluated program demographics and the relative importance of 23 different selection criteria used by ophthalmology residency program directors when evaluating applicants for residency interviews (Likert scale 1–5, with 1 being “not important” and 5 being “very important”). Program directors were also asked to identify the one factor they felt was most important.
Results The overall residency program director response rate was 56.5% (70/124). The selection criteria with the highest average importance scores were core clinical clerkship grades (4.26/5) followed by letters of recommendation (4.06/5), and United States Medical Licensing Examination (USMLE) Step 1 score (4.03/5). The most frequently cited single most important factor for interview selection was core clinical clerkship grades (18/70, 25.7%), with USMLE Step 1 score (9/70, 12.9%) and rotations at the program director\u27s department (6/70, 8.6%) also commonly reported.
Conclusion Our results suggest that core clinical clerkship grades, letters of recommendation, and USMLE Step 1 scores are deemed the most important selection criteria by ophthalmology residency program directors as of a 2021 survey. With changes in clerkship grading for many medical schools and changes in national USMLE Step 1 score reporting, programs will face challenges in evaluating applicants and the relative importance of other selection criteria will likely increase
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
