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
The Status of Epistemological Superiority in the Medical Landscape of South Africa
No full textThe article begins with sketching out narratives around indigenous medicine in South Africa and around its ostensible counterpart ‘modern’, Western medicine. As the former was officially tried to be kept in check by limiting it to its traditional roots, the dissection of the concept of tradition is necessary in order to understand if 'tradition' is really as static as is often assumed. The results clarify that the difference between 'traditional' South African knowledge and 'scientific' Western knowledge is rather a question of narrative than of actual facts. Comparing the legal situation of healers during colonialism and apartheid in South Africa brings to light that the ostensible difference between Western and traditional medicine is of a constructed nature rooted in the different legal treatment of these ways of healing.The second part of the essay assesses whether the prevailing epistemological superiority of Western medicine during colonialism and apartheid has vanished over time. Doing so requires taking a close look at who is able to produce knowledge, how it can be produced and secured. Knowledge production concepts such as hybridity and creolisation are closely examined, delineated and evaluated. This is necessary to critically discuss the ways in which 'traditional' knowledge is treated by the state and to what extent the existing forms of cooperation between the two medical approaches can be regarded as on eye-level
Análisis postcolonial del estatus de la igualdad epistemológica en el ámbito médico sudafricano
No full textEl artículo comienza esbozando narrativas sobre la medicina indígena en Sudáfrica y sobre su aparente contrapartida ‘moderna’, la medicina occidental. Puesto que la primera se intentó mantener oficialmente bajo control limitándola a sus raíces tradicionales, se hace necesario analizar el concepto de tradición para comprender si la ‘tradición’ es realmente tan estática como se suele suponer. Los resultados esclarecen que la diferencia entre el conocimiento ‘tradicional’ sudafricano y el conocimiento ‘científico’ occidental es, más bien, una cuestión de narrativa que de hechos objetivos. Una comparación entre la situación legal de los sanadores durante el colonialismo y el apartheid en Sudáfrica muestra que la aparente diferencia entre las medicinas occidental y tradicional es de naturaleza construida, originada en el diverso tratamiento legal que han recibido estas maneras de curar.La segunda parte del ensayo evalúa si la reinante superioridad epistemológica de la medicina occidental durante el colonialismo y el apartheid ha ido desapareciendo con el tiempo. Para hacer esto es necesario mirar de cerca para ver quién es capaz de producir conocimiento, cómo se puede producir y cómo se puede asegurar. Se examinan, definen y evalúan atentamente conceptos relativos a la producción de conocimiento, tales como la hibridez y la criollización. Esto es necesario para abordar críticamente cómo el estado trata el conocimiento ‘tradicional’ y hasta qué punto las formas existentes de cooperación entre ambos enfoques médicos se pueden considerar al mismo nivel
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
