Sentire il groove: aspetti percettivi e partecipativi
Full text linkThe study of groove is part of a general re-evaluation of rhythm that took place towards the end of the 20th century. The phenomenon of groove is commonly associated with pleasurable involvement and synchroniza- tion with musical rhythm, inducing responses that are expressed in body movements and psychological entrainment. In syntactic/structural theo- ries, groove is believed to emerge from a combination of cyclically repeat- ed rhythmic lines, while in processual/performative interpretations, it is considered in terms of a musician’s embodied rhythmic sensibility or as the result of interplay in ensemble performance. Whether groove is con- sidered in terms of ‘text’ or performance, scholars often refer to a unified set of parts, similar to the psychological concept of Gestalt. This essay aims to place groove among the pillars of a more general aesthetic theory of popular music, evaluating both the expressive-performative and delib- erately machinic aspects of programmed and electronic popular music. Thus, groove is seen as an aesthetic trait aimed at encouraging direct and immediate participation, which occurs through active and embodied ex- periences and not through formal intellectual contemplation

The effect on the macular function of laser photocoagulation for diabetic macular edema.
No full textThe benefit of focal and grid-laser photocoagulation in reducing the risk of visual loss from diabetic macular edema has been established. In order to investigate the effect of this treatment on macular function, 30 diabetics with macular edema and 1.0 visual acuity were tested before and after laser treatment at intervals of 1 week, and 1 and 3 months, respectively. The test was carried out by means of nyctometry, contrast sensitivity, hue discrimination and critical flicker frequency of blue cones. All patients had abnormal results in macular tests before treatment. During the follow-up, visual acuity remained stable and the macular tests did not statistically modify, except for nyctometry, which deteriorated at the 1-week follow-up (P = 0.02) and then increased to the basal values, and contrast sensitivity [improved at the last control (P = 0.006)]. Clinical regression of macular edema was observed, but macular function tests never normalized. Patients with diabetic macular edema and good visual acuity should be monitored with many functional methods, and laser treatment should be performed before macular function deteriorates irreversibly
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
