Modificações físico-químicas na carne in natura bovina decorrentes da alta pressão hidrostática.
No full textO Brasil tem se mostrado como grande potência em produção e exportação de carne, porém, abaixo de seu potencial de mercado, por abater, em sua maioria, animais zebuínos ou azebuados, os quais possuem reconhecidamente uma carne “menos macia”. O atributo maciez é o principal fator de qualidade relacionado à carne para exportação; nesse sentido, são estudados e empregados métodos de amaciamento, como a maturação convencional, relacionada à ação de enzimas proteolíticas. Mais recentemente, tem sido pesquisado o processo de alta pressão hidrostática (APH), que tem se mostrado promissor para, em menor período de tempo, propiciar o amaciamento de carne e de produtos cárneos, não implicando em grande aumento da temperatura durante o processamento e, dessa forma, modificando minimamente as características originais dos produtos. Esta revisão aborda a aplicação do processo de alta pressão hidrostática sobre a carne in natura e as modificações decorrentes nas características físico-químicas, abrangendo a importância e as perspectivas de aplicação dessa tecnologia para a melhoria da qualidade do produto

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
Azeitonas de mesa no Brasil: mercado, tecnologia e aspectos legais
Get PDFAzeitona de mesa é o produto vegetal fermentado de maior importância no mundo ocidental. Apesar de não possuir produção significativa, o Brasil está entre os dez maiores consumidores de azeitona de mesa do mundo. Para o ano safra 2013/2014 (período entre os dias 01 de outubro até 30 de setembro), estima-se que o país seja o segundo maior importador e o nono maior consumidor do fruto. No entanto, as características do fruto e os principais processos de elaboração de azeitonas de mesa são pouco conhecidos no Brasil. Dessa maneira, este trabalho objetiva realizar um levantamento do mercado, as principais tecnologias utilizadas e os aspectos legais associadas à produção de azeitona de mes
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
