Time matters - The effect of time delays before and after goal directed reaching in visuomotor adaptation
Get PDFThrough movement, we as humans can interact with our environment. Every movement takes place in a certain temporal context, because the right movement at the wrong time or the right movement coordinated differently in time can lead to a completely different, possibly wrong result. But not only the timing of the individual motor commands is important, also differences in the available time for the neuronal processes underlying the movement, such as movement planning or evaluation, can have an enormous influence. Time itself is often one of the most important variables in behavioral experiments, but also one of the most difficult ones to control.
Thematically, this thesis focuses on the separation of adaptation into an explicit and an implicit component, and how through the manipulation of different time intervals in visuomotor rotation tasks, these can influence computational principles of visuomotor adaptation. First of, drawing on the example of the incomplete asymptote of adaptation, a phenomenon that shows that participants in such trials compensate for perturbation but usually leave a substantial residual error. It has been shown that this residual error is magnified when the time available for planning and preparing the movement is artificially reduced. This thesis shows that prolonging preparation time affects the asymptote in a similar way and can be the solution to overcoming residual errors. Furthermore, some studies have been able to show that a time delay of movement feedback leads to explicit processes becoming prevalent. Under this premise, this thesis investigated the phenomenon of temporal discounting of reward and showed that the explicit component can in fact overcome discounting. As most of the studies use some form of direct methods to measure for the explicit and implicit participation of adaptation, last but not least, this thesis attempted to use EEG, more specifically an event related potential, the feedback related negativity, as a proxy for mapping explicit and implicit processes at the neuronal level
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
