Interview avec Preetha Ram, CEO of OpenStudy.com
J'ai décidé d’interviewer à Mme Preetha Ram, une américaine leader en l’éducation, qui a développé une start-up dans le cadre de l’apprentissage et de l’enseignement en ligne. Je trouve ce sujet très intéressant pour découvrir le monde de la création de nouveaux services pour le e-learning qui ne font pas partie d’une institution éducative. Le but de OpenStudy.com est de créer un site internet où les étudiants peuvent se rencontrer pour s’aider les uns les autres à étudier, pour trouver des..
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
Problem-based learning in undergraduate education. A sophomore chemistry laboratory
For the first time in my life what we were doing in lab had meaning to the outside world other than just mixing chemicals together. -Comment turned in by a student in Chem. 291L Problem-based learning (PBL) is a pedagogical approach based on recent advances in cognitive science research on human learning (1). A PBL classroom is organized around collaborative problem-solving activities that provide a context for learning and discovery. PBL has been used in medical schools to enhance the development of clinical reasoning skills and to promote the integration of basic biomedical sciences with clinical applications. Medical education literature is replete with articles on the practice and evaluation of PBL methods, but there is very little published on the application of PBL for science education in undergraduate settings. A recent paper by Dods in this Journal describes a very interesting application of PBL in a biochemistry lecture course (2). There have been some presentations at recent ACS conferences describing the application of PBL in chemistry courses (3, 4 ). Other problembased approaches to pedagogy have been described by Wenzel and Hughes (5, 6 ). These approaches are similar to PBL in that students learn in the context of an authentic problem solving experience. This paper describes the implementation of PBL pedagogy in an undergraduate classroom setting. The author provides a brief description of PBL philosophy and PBL protocols, guidance on how to choose and design a PBL problem and integrate it into the curriculum, and a description of a laboratory course in which PBL has been successfully implemented
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
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
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
