The Threshold of Representations Integrating Semiotics and the Cognitive Sciences
No full textRepresentations are core epistemic entities of both cognitive sciences and semiotics. The latter can be used as a theoretical resource to better define the object of study "representation", and to provide clarity over the use of this concept. In doing so, it can offer interesting insights to intervene into the debate on representational formats elaborated in the cognitive sciences. Semiotics may function as an instrument of criticism in the discussion of an increasingly popular representational format, which has been postulated to explain situated embodied action: action-oriented representation. In addition, an approach to embodied action that integrates some insights from Peirce's semiotics with the theory of cognitive niches may offer a different theoretical perspective on the problem that action-oriented representations are supposed to explain
When Affective Relation Weighs More Than the Mug Handle: Investigating Affective Affordances
Full text linkEnactive and embodied approaches to cognition are becoming increasingly interested in the affective dimension of human experience. Consistently, this issue has been addressed in empirical research, which is paying growing attention to the affective quality of social contexts by addressing motor simulations, joint actions, emotional disorders, and body psychotherapy.
Still, while in the relationship between two or more agents the involvement of the affective variable, even when uninvestigated, is intrinsically evoked, in the case of the agent-object relationship the recognition of such engagement requires more specific care.
In laboratory-based studies, when dealing with an object and an observer, the practical opportunities that she is able to perceive and use have been mainly operationalized referring to visual manipulable properties of the object, as shape and orientation, associated with its canonical use. Progressively empirical research introduced, and manipulated, also the physical context, and the required responses, distinguishing between functional and volumetric gestures. Are these ‘affordances’? Strictly speaking no, as these accounts clash with direct perception, but they are undoubtedly elegant approaches suitable for outlining answers (also) to most questions of ecological psychology.
In light of the heated debate on affordances between philosophers and cognitive scientists, we propose to draw upon literature in both fields as our aim is twofold. (1) Exploring the great absentee of empirical investigations conducted so far: the affective dimension of perception-action coupling of our relationship with the physical context. To this end a clarification of the philosophical concept of ‘affective affordance’ would be essential. (2) Specifying some criteria of definition for this construct and suggesting an analysis of AAs in its application to the individual human agent’s practice – for our proposal to be not only theoretical, but suitable for experimental investigation, promoting a constructive dialogue between philosophy and empirical psychology
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Full text link“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
Full text linkWe 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
Full text linkWe 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
