Introduction. Dance research and transmedia practices
No full textContemporary dance is a field full of interpretative possibilities for a Semiotics interested in dynamic and performance open texts connected to theatre practice and/or multimedia. If dance manifests itself as a choreographic discourse/text formed through a creative process then, in order to investigate expression and contents in their narrative or plastic nature, it will be appropriate to take into consideration a series of issues related to the dimension of the senses, but also the figurative and the interpretative dimensions, from the point of view of dance main semiotic actors (dancer, choreographer, audience). Dance as a process, dance as discourse, text analysis, notation, technology, translation, arts, body, are therefore only some of the key words used in this monographic issue, together with the notions of performance - intended both as discourse and process - in the multiple semantic possibilities of a word in which spectacular conceptions and more semiotic ones, although overlapping, are all predominantly considered in virtue of live execution
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
Characterizing the Spectral Energy Distribution of blazars as candidates for neutrino emission
No full textBlazars are potential neutrino emitters as suggested by the detection of a high-energy neutrino in the direction of the flaring Blazar TXS 0506+056, in 2017. However, the origin of neutrinos from this source is still unclear. This work aims at finding and characterizing other Blazars with similar features as TXS 0506+056. We selected sources from the most recent Fermi Catalogue, the 4LAC, finding 4 candidates. They were characterized through a multiwavelength analysis, which revealed some peculiarities in the SED of the candidate
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
Benefits of pre-treating MSWI fly ash before alkali-activation
No full textThe significant amount of heavy metals and soluble salts contained in municipal solid waste incineration fly ash (MSWI FA) and the corresponding risk of leaching make them classified as hazardous waste. Nowadays, the ashes are usually landfilled, but another application can be the inertization and valorization of MSWI FA in building materials. Geopolymer can be a potential material because it can naturally entrap heavy metals physically and chemically inside its matrix. This research investigated how the use of electrodialytic treatment compared to a water washing procedure, considered as pre-treatments for MSWI FA, influenced a metakaolin-based geopolymer as an encapsulation matrix for MSWI FA. Geopolymers with metakaolin and 5, 10, 20 wt% of raw or pre-treated MSWI FA were compared with a sample containing only metakaolin for environmental, mechanical, and physical properties. The formation of aluminosilicate gel was confirmed for all geopolymers, although with varying degrees of impurities. The results show low compressive strength for the sample with washed ash but good mechanical strength for geopolymers with raw and electrodialytic treated ash compared to metakaolin-based geopolymer or with geopolymer with washed ash. A decrease in leaching for all the metals in the samples confirms the encapsulation capacity of geopolymers. The electrodialytic pre-treatment decreases, particularly the leaching of Cr, Zn and chloride in geopolymers, confirming the potential use of this pre-treatment to improve the environmental and mechanical characteristics of geopolymers with MSWI FA
