COMPOSER: UM AMBIENTE DE AUTORIA DE DOCUMENTOS NCL PARA TV DIGITAL INTERATIVA
No full textCom o advento da adoção de um padrão de TV digital
interativa pelo Brasil,
tem crescido o interesse pela análise das possíveis
alternativas nas mais diversas
áreas que compõem um sistema de TV digital. No caso do
Brasil, NCL é a
linguagem declarativa adotada para modelagem de aplicações
interativas no
Sistema Brasileiro de TV Digital Terrestre (ISDTV-T -
International System for
Digital TV). Nesse contexto, este trabalho apresenta a
ferramenta Composer, um
ambiente de autoria voltado para a criação de programas
NCL para TV digital
interativa. Da mesma forma como no editor HyperProp, no
qual é baseado, no
Composer as abstrações são definidas nos diversos tipos de
visões que permitem
simular um tipo específico de edição (estrutural,
temporal, leiaute e textual). Essas
visões funcionam de maneira sincronizada, a fim de
oferecer um ambiente
integrado de autoria. Além de ter sua interface gráfica e
funcional remodelada,
principalmente a visão temporal, problemas de
representação e edição de objetos
de mídia, relacionamentos de sincronismo entre objetos,
dentre eles os
relacionamentos interativos, e edição ao vivo são
tratados. Em resumo, o sistema
proposto visa facilitar e agilizar a criação de aplicações
voltadas para TV digital
abstraindo do autor toda, ou pelo menos parte da
complexidade de se programar
em NCL através desse ambiente de autoria.With the advent of adoption of an interactive digital TV
standard by the
Brazilian government, the interest for the analysis of
possible alternatives in
several areas that compose a digital TV system has
increased. In the case of
Brazil, NCL is the declarative language adopted for
modeling interactive
applications in the Brazilian Terrestrial Digital TV
System (ISDTV-T -
International System for Digital TV). In that context,
this work presents
Composer, an authoring tool to create NCL documents for
interactive digital TV.
In the same way that in the HyperProp editor, in which it
is based, in Composer
the abstractions are defined using views that allow to
simulate a specific type of
edition (structural, temporal, layout and textual). Those
visions work in a
synchronized way, in order to offer an integrated
authoring tool. Besides having
the user and the functional interface remodeled, mainly
its temporal view,
problems of representation and edition of media objects,
relationship problems,
amongst then the interactive relationships, and live
edition are treated. In
summary, the proposed system tries to make easier the
creation of documents for
digital TV abstracting from the author all, or at least
some complexity of
programming in NCL using this authoring tool
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
