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
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
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
Formative Feedback Passport: A Tool to Engage Students in Reflecting on and Incorporating Mid-Point Feedback
Get PDFBACKGROUND: The importance of formative feedback in undergraduate medical education is widely appreciated; however, it is historically inadequate. The formative feedback passport (FF tool) was developed and implemented in the Internal Medicine (IM) clerkship at UT Southwestern to address these concerns.
OBJECTIVE: This dissertation examines the FF tool's role in facilitating an optimal formative feedback process.
METHODS: Initially, a pre-intervention study was conducted, in which randomly selected, de-identified FF tools from the 2018-2019 IM clerkship were analyzed for content and quality of student reflection. Results revealed that student reflection on feedback was insufficient, with transformative, thoughtful reflection seldom occurring. In response to these findings, the FF tool's instructions were augmented with a module to encourage critical reflection. Subsequently, a post-intervention study was conducted, in which randomly selected, de-identified FF tools from the 2020-2021 IM clerkship were analyzed in the same manner as the pre-intervention study.
RESULTS: 149 feedback tips from 50 FF tools were included in the pre-intervention study, and 162 feedback tips from 54 FF tools were included in the post-intervention study for a total of 311 feedback tips from 104 FF tools analyzed. In both studies, most of the feedback tips aligned with established standards for resident and faculty evaluators. In addition, the mean scores for each REFLECT Rubric criterion were significantly higher in the post-intervention group than the pre-intervention group.
CONCLUSION: The FF tool is an invaluable electronic feedback tool in the IM clerkship at UT Southwestern. It enables documentation of formative feedback and promotes critical student engagement, reflection upon feedback, and the development of plans to implement feedback for improvement. Study results demonstrate that students receive formative feedback from an attending, resident, or patient that is appropriate in content. Additionally, study results demonstrate that the intervention improved student engagement and quality of reflection on feedback using the FF tool
Physician Estimated Depth: Can It Reduce Unnecessary CT Scan Evaluation of Pectus Excavatum?
Get PDFThe 57th Annual Medical Student Research Forum at UT Southwestern Medical Center (Tuesday, January 22, 2019, 3-6 p.m., D1.600)BACKGROUND: The severity of pectus excavatum is determined by computed tomography (CT) derived indices such as the Haller Index (HI) and the Correction Index (CI). Physician estimated depth (PED) as an alternative measurement may preclude for CT. We retrospectively evaluated PED as a screening tool to identify surgical candidates.
METHODS: Patients with a diagnosis of pectus excavatum between 1/1/2009 and 3/30/2018 were extracted from the electronic health record for review. Patients without available imaging were excluded. HI and CI were calculated from CT images. CT derived measurements acted as an approximation of PED. Using ROC analysis, we estimated the optimal PED cut-off for identifying surgical candidates according to an HI ≥ 3.25.
RESULTS: A total of 94 patients were identified and all met inclusion criteria. Patients were predominantly males (82%) with a median age of 15 (IQR=14-16). Almost half (46%) were underweight (BMI < 18.5). The median HI was 4.1 (IQR=3.7-5.1) with 89% ≥ 3.25. The median CI was 39 (IQR=29-47). CI was highly correlated with HI (r=0.77, area under the curve, AUC=0.88). A CI of 27 was best at correctly classifying HI above/below 3.25 (sensitivity, Se=89%, specificity, Sp=90%). Median PED was 2.5 (IQR=2.1-3.0). Overall, a PED of 2cm correctly classified 86% of HI above/below 3.25 (Se=88%, Sp=70%, AUC=0.84). Among underweight patients, ROC parameters improved (93% correctly classified, Se=95%, Sp=75%, AUC=0.92). PED was highly correlated with CI (r=0.77, AUC=0.94). Among underweight patients, a PED of 2cm correctly classified 95% of CI above/below 27 (Se=97%, Sp=80%, AUC=95%).
CONCLUSION: PED over 2cm can accurately identify patients who require CT imaging and pectus correction. Our findings show that PED may be employed easily in the clinic as a screening tool, thereby minimizing unnecessary CT scans. A prospective evaluation of PED is underway at our center.Southwestern Medical Foundatio
