Enhancing anatomy learning: A concept map-based approach for first-term MBBS students
No full textBackground: The complexity of the subject content, and its 3D orientation in anatomy makes students difficult to learn, assimilate, and recapitulate the topics. There is a need for innovative teaching methods in anatomy for better understanding of the subject and improved performance of students. In this context, an attempt is made to use concept maps as a tool for learning anatomy. Material and methods: After obtaining ethical committee approval and informed consent, 128 first-term MBBS students were divided into 2 groups, 64 in the study and the control group. After the lecture on each topic from anatomy (radial nerve, median nerve, and ulnar nerve), a pre-test was conducted on 128 MBBS students. Post-test multiple-choice questions-based assessment was conducted for both groups after 1 week of each lecture. Difference in knowledge by comparing the assessment scores of the study group and control group. A feedback form with a 5-point Likert scale was administered to all students at the end of 3 sessions. Mann–Whitney U-test and Wilcoxon signed-rank test were applied to check the significance (p≤.01) of the results. Results: There was a statistically significant difference between the 2 groups during the pre-test for cognition, and total scores and the post-test for recall, cognition, and total scores. 98% of students perceived that the concept map-based approach helped better retain the topic. Conclusions: Concept maps promote comprehensive learning and applying knowledge in new situations. From this study, we recommend that concept mapping can be a pedagogical tool in Anatomy. Resumen: Antecedentes: La complejidad del contenido de la asignatura y su orientación 3D en Anatomía dificulta que los estudiantes aprendan, asimilen y recapitulen los temas. Existe la necesidad de métodos de enseñanza innovadores en Anatomía para una mejor comprensión de la materia y un mejor rendimiento de los estudiantes. En este contexto, se intenta utilizar los mapas conceptuales como herramienta para el aprendizaje de Anatomía. Material y métodos: Después de obtener la aprobación del comité ético y el consentimiento informado, 128 estudiantes de primer semestre de MBBS se dividieron en 2 grupos, 64 en el estudio y el grupo control. Después de la conferencia sobre cada tema de Anatomía (nervio radial, nervio mediano y nervio cubital), se realizó una prueba previa a 128 estudiantes de MBBS. Se realizó una evaluación posterior a la prueba basada en MCQ para ambos grupos después de una semana de cada conferencia. Diferencia en el conocimiento al comparar las puntuaciones de evaluación entre el grupo de estudio y el grupo de control. Se administró a todos los estudiantes un formulario de retroalimentación con una escala Likert de cinco puntos al final de 3 sesiones. Se aplicaron la prueba U de Mann Whitney y la prueba de rangos con signo de Wilcoxon para comprobar la significancia (p ≤ 0,01) de los resultados. Resultados: Hubo una diferencia estadísticamente significativa entre los dos grupos durante la prueba previa de cognición y puntuaciones totales y la prueba posterior de memoria, cognición y puntuaciones totales. El 98% de los estudiantes percibió que el enfoque basado en mapas conceptuales ayudó a retener mejor el tema. Conclusiones: Los mapas conceptuales promueven el aprendizaje integral y la aplicación del conocimiento en situaciones nuevas. A partir de este estudio, recomendamos que los mapas conceptuales pueden ser una herramienta pedagógica en Anatomía
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
Hyperostosis Frontalis Interna and Temporalis Interna: A Rare Case Report
Get PDFHyperostosis is a slow-growing benign bone tumour often seen in the bones of the cranial vault, more commonly found in elderly females. It is an incidental finding noted during radiological examination. The clinical manifestation of such tumour depends on its location inside the cranial cavity: the proximity to the paranasal sinuses, brain tissue, nerves, or blood vessels, etc. Its clinical findings may range from mild obstruction of the paranasal sinuses or blood vessels to severe compression of the surrounding cranial nerves. Here a rare case of hyperostosis of the frontal and temporal bones found during a routine cadaveric dissection in the Department of Anatomy is presented. Causes of the formation of such unusually enlarged bone masses inside the cranial cavity and their clinical presentation 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
