L’histoire de l’université à distance pionnière au Royaume-Uni : l’Open University - Entretien avec Martin Weller
Get PDFIn his interview, Professor Martin Weller explains the origins of the Open University, the UK’s pioneer distance education university, and describes the different contexts in which the Open University has had to navigate through in the last 50 years. The interview focuses on showing how the Open University’s mission (to be ‘open to people, places, methods and ideas’) has been at the heart of the institution’s developments, and how the concept of openness has evolved throughout the changes and the challenges of the recent years.En su entrevista, el profesor Martin Weller explica los orígenes de la Open University, la universidad a distancia pionera en el Reino Unido, y describe los diferentes contextos en los que la Open University ha tenido que desenvolverse en los últimos 50 años. En sus comentarios, destaca, por un lado, el importante papel que su misión (estar "abierta a las personas, a los lugares, a los métodos y a las ideas") ha desempeñado en el desarrollo de la institución y, por otro, cómo esta noción de apertura ha evolucionado a través de los cambios y de los retos a los que se ha enfrentado la universidad a lo largo del tiempo. Dans son entretien, le professeur Martin Weller parle des origines de l’Open University, l’université à distance pionnière au Royaume-Uni, et décrit l’évolution de l’Université depuis sa création, il y a 50 ans. Dans ses propos, il souligne, d’une part, l’importance du rôle qu’a joué la mission de l’Open University (être « ouverte aux gens, aux lieux, aux méthodes et aux idées ») dans les développements de l’établissement et, d’autre part, la manière dont cette notion d’ouverture a évolué au travers des changements et des défis auxquels l’Université a dû faire face au fil du temps
Metaphors of Ed Tech, 2022. By Martin Weller. Athabasca University Press. 192 pages. ISBN 9781771993500
Get PDFIn Metaphors of Ed Tech, Martin Weller explores the field of learning technology in both the broadest and deepest senses. Weller chooses the application of metaphors as a method, and the resulting book reads more like an enjoyable set of ruminations than rigorous investigation. Weller has long employed metaphors and analogies on his blog, going back to 2006, and in this book he sets out to apply this “more playful aspect of thinking and writing about educational technology (ed tech)” across its practice and culture (p. 3)
La battaglia per l'Open
No full textCon il successo delle pubblicazioni ad accesso aperto, dei Massive open online courses (MOOC) e delle pratiche di open education, l’approccio aperto all’istruzione si è spostato dalla periferia alla scena centrale. Questo segna un momento di vittoria per il movimento open education, ma allo stesso tempo fa iniziare la vera battaglia per la direzione che l’openness deve prendere. Come per il movimento green, l’openness ha ora un valore di mercato ed è soggetta a nuove tensioni, come ad esempio i venture capitalist che finanziano le società MOOC. Questo è un momento cruciale per determinare la direzione futura dell’open education. In questo volume, Martin Weller esamina quattro aree chiave che sono state fondamentali per gli sviluppi nell’ambito dell’open education: accesso aperto, MOOC, risorse didattiche aperte e ricerca scientifica aperta. Esplorando le tensioni all’interno di queste aree chiave, sostiene che capire chi detterà la futura direzione dell’openness è significativo per tutti coloro che sono interessati al tema dell’istruzione. La traduzione italiana di Simone Aliprandi rende l’opera più facilmente fruibile ai lettori italiani e la postfazione di Elena Giglia apporta preziosi spunti di approfondimento e di aggiornamento
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
