A interação no livro digital em formato EPUB: potencialidades da hipermídia em obras histórico-regionais
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão, Programa de Pós-Graduação em Design e Expressão Gráfica, Florianópolis, 2013.Esta dissertação apresenta como principal eixo a análise do potencial interativo de livros digitais de formato ePub acessados a partir de dispositivos tablets. Inicialmente é apresentado um levantamento bibliográfico sobre os conceitos do livro digital e sua contextualização tendo em vista o atual cenário do sistema editorial. Posteriormente, estabelece-se a relação da navegação e da interface gráfica de livros digitais de formato ePub com os recursos hipermidiáticos de texto, som, imagem, animação e vídeo. Como delimitação da pesquisa, o estudo propõe um aprofundamento nas potencialidades de interação do livro digital em obras de caráter histórico-regional, por considerar esse gênero de publicação de extrema relevância no contexto social e acreditar que, com a utilização da hipermídia no livro digital, os registros e as narrativas históricas possam ter um destaque ainda maior e proporcionar uma interação mais imersiva por parte dos leitores que terão a possibilidade de ler, ver e ouvir os acontecimentos histórico-regionais relatados nessas obras. O método de pesquisa adotado envolveu, após a etapa de revisão de literatura, o projeto e a avaliação da interação de um livro histórico-regional em formato ePub. Livro este desenvolvido no Laboratório de Hipermídia da Universidade Federal de Santa Catarina e disponibilizado para avaliação em um dispositivo tablet. Os ensaios de interação realizados, somados às técnicas de observação e de entrevistas, objetivaram verificar as especificidades da interação dos usuários com os elementos hipermidiáticos apresentados na obra. Como resultados alcançados, percebeu-se que os elementos de hipermídia inseridos em livros histórico-regionais em formato ePub potencializam o nível de interatividade e garantem uma compreensão mais realista das informações contidas na obra. Por meio do ensaio de interação constatou-se que a exploração dos recursos de vídeo, demonstrando cenas dos acontecimentos históricos presentes na obra, e da relação entre o texto e o áudio correspondente aos depoimentos das fontes orais citadas pelo autor do livro, despertaram interesse e apreciação dos participantes. Os resultados contribuirão para direcionar futuras pesquisas sobre o uso da hipermídia em livros digitais e potencializar a inserção de recursos interativos em obras de caráter histórico-regional. Abstract : This dissertation presents the analysis as the main axis of the interactive potential of digital books in ePub format accessed from tablets devices. Initially we present a literature review about the concepts of digital book and its context in view of the current scenario of the editorial system. Later, we establish the relation of the navigation and the graphic interface of digital books in ePub format with hypermediatic resources of text, sound, image, animation and video. As delimitation of the research, the study proposes a deepening in the potential interaction of digital book in works of historical-regional stamp by considering this genre of publication as extremely relevant in the social context, and believe that with the use of hypermedia in the digital book records and historical narratives may have an even greater emphasis and provide a more immersive interaction from readers who will be able to read, see and hear the historical-regional events reported in these works.The research method used includes, after the step of literature review, the project and evaluation of the interaction of a historical-regional book in ePub format. That book was developed in Hypermedia Laboratory of the Universidade Federal de Santa Catarina and available for evaluation on a tablet device. The tests for interaction performed, combined with the techniques of observation and interviews, aimed to verify the specifics of the interaction of users with hypermedia elements presented in the work. As results, it was noticed that the elements of hypermedia inserted into historical-regional books in ePub format potentiate the level of interactivity and ensure a more realistic comprehension of the information contained in the work. Through interaction assay was found that the exploitation of video resources, showing scenes of historical events contained in the work, and the relationship between text and corresponding audio to the testimony of oral sources cited by the author of the book, aroused interest and enjoyment of the participants. The results will help to guide future research about the use of hypermedia in digital books and enhance the inclusion of interactive features in works of historical-regional stamp
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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
No full text“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
No full textWe 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
