Using ICTs as a pedagogical resource to facilitate epistemological access in science with teacher education students
Get PDFPhilosophiae Doctor - PhDThe study aimed to investigate the kind of knowledge privileged when student teachers use Information Communication Technologies in facilitating learning in science subjects. The assumptions were that future student teachers, through their pedagogic practices, may either reproduce or interrupt educational inequalities. The ability to interrupt inequalities is conditioned by the manner in which these student teachers have been inducted into the field of teacher education and this process includes the ability to manipulate technological resources to facilitate epistemological access. This concept originally coined by Morrow in the 1980s looked at black students seeking entry to university. Since then the concept was used to signify the importance of knowledge in the curriculum. In this study, the exploration of epistemological access goes beyond physical or formal access and includes meaningful access to knowledge. The semantics dimension of Legitimation Code Theory (LCT) proposed by Maton was used, with a particular focus on semantic density (SD) as a theoretical framework. Maton argues that semantic density can vary across teaching practices and contexts. The study assumes that student teachers, through their pedagogic practices, may either reproduce or interrupt educational inequalitie
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
Communography in Phyllis Naidoo's "Charlie and Jo"
No full textPhyllis Naidoo’s Footprints beyond Grey Street (2007) adjusts conventional
boundaries of the autobiographical genre: it is written by Naidoo but appears not to
be principally concerned with the author’s life. It is written largely about her comrades
in the African National Congress who were in exile in African countries. Of the stories
in Naidoo’s “autobiography”, “Charlie and Jo” in particular epitomises the absence of
the author: a stylistic and generic anomaly which merits particular attention and thus
forms the focus of this article. This memory-tale of social recollection evidences
autobiographical self-displacement: the privileging of collective memory as opposed
to an individual’s nostalgic journey towards self-definition. This foregrounding of a
collective identity has been identified and termed communography in the writings of
comparable political groups such as the Irish Republican Army. d termed communography in the writings of comparable political groups such as the Irish Republican Army
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
