    Trata-se, no presente artigo, de uma análise de aspectos principais do debate teórico acerca da hermenêutica e da crítica e suas respectivas pretensões de universalidade, ocorrido entre Hans-Georg Gadamer e Jürgen Habermas, entre as décadas de 60 e 70 do século XX. Neste artigo, destacaram-se posições divergentes e convergentes entre Gadamer e Habermas. Buscou-se revelar não apenas a controvérsia, mas também a complementariedade entre ambos e entre hermenêutica e crítica, como manifestações vivas do pensamento filosófico contemporâneo

    Orientador: Claudina Izepe RodriguesDissertação (mestrado) - Universidade Estadual de Campinas, Instituto de Matematica, Estatistica e Computação CientificaResumo: 0 objetivo principal deste trabalho é apresentar uma classificação para os dígrafos semicompletos hamiltonianos, extendendo os resultados obtidos para os torneios. Para isso utilizamos da teoria da homotopia regular de grafos de Davide C. Demaria, apresentando resultados sobre torneios simplemente desconexos, a caracterização de torneios por 3-ciclos e o conceito de ciclo conado e não-conado para dígrafos, introduzido por Kiihl e Tironi. Com a noção de ciclo minimal e característico para dígrafo uma classificação para os dígrafos semicompletos hamiltonianos surge então naturalmente. Esses resultados, quando encontrados para torneios, proporcionaram a obtenção de uma classe de torneios reconstrutíveis (torneios normais) e pesquisa nesse sentido deve ser efetuada para dígrafos. Apresentamos em apêndice a matriz de um dígrafo, os torneios de moon, normais e, brevemente, o problema da reconstrução de grafosAbstract: The main target in this work is to present a classification for the hamiltonian semicomplete digraphs, extending the results previously obtained for the tournaments. In this way we apply the regular homotopy of finite directed graphs theory developed by Davide G. Demaria, presenting results on simply disconnected tournaments, on the caracterization of tournaments by 3-cicles and the concept of coned and non-coned cicle for digraphs, introduced by Kiihl and Tironi. With the notion of minimal and caracteristic cicle we naturally get a classification of the semicomplete hamiltonian digraphs. These results, when used for tournaments led to a new class of reconstructible ones (named normal) and future research on the extension of these results for digraphs in general seems to be interesting. We present in appendixes the array of a digraph, the tournaments of Moon, Normal and, briefly, the reconstruction problem for graphsMestradoMestre em Matemátic

    O Mercado Cultural e o Protagonismo Feminino: A Música da Jovem Guarda

    Get PDF
    O movimento musical da Jovem Guarda, surgido nos anos 1960, teve grande impacto na modernização do mercado musical brasileiro, influenciando o consumo cultural e o comportamento. Este estudo analisa uma de suas características fundamentais: o protagonismo feminino nesse mercado, o qual influenciou as mulheres brasileiras na revolução dos costumes. A partir do sucesso de artistas como Wanderléa, Martinha, Rosemary, Elizabeth, Vanusa - e da influência de sua imagem e discurso nas mídias -, as mulheres jovens da época lideraram uma verdadeira revolução de comportamento no Brasil, quebrando o tabu da virgindade, adotando a pílula como método anticoncepcional, a moda como expressão de uma nova liberdade e a ambição profissional como novo horizonte de vida. A Jovem Guarda não assumia conotações ideológicas, mas sua influência foi fundamental na modernização da sociedade brasileira

    AtPIN: Arabidopsis thaliana Protein Interaction Network

    <p>Abstract</p> <p>Background</p> <p>Protein-protein interactions (PPIs) constitute one of the most crucial conditions to sustain life in living organisms. To study PPI in Arabidopsis thaliana we have developed AtPIN, a database and web interface for searching and building interaction networks based on publicly available protein-protein interaction datasets.</p> <p>Description</p> <p>All interactions were divided into experimentally demonstrated or predicted. The PPIs in the AtPIN database present a cellular compartment classification (C<sup>3</sup>) which divides the PPI into 4 classes according to its interaction evidence and subcellular localization. It has been shown in the literature that a pair of genuine interacting proteins are generally expected to have a common cellular role and proteins that have common interaction partners have a high chance of sharing a common function. In AtPIN, due to its integrative profile, the reliability index for a reported PPI can be postulated in terms of the proportion of interaction partners that two proteins have in common. For this, we implement the Functional Similarity Weight (FSW) calculation for all first level interactions present in AtPIN database. In order to identify target proteins of cytosolic glutamyl-tRNA synthetase (Cyt-gluRS) (AT5G26710) we combined two approaches, AtPIN search and yeast two-hybrid screening. Interestingly, the proteins glutamine synthetase (AT5G35630), a disease resistance protein (AT3G50950) and a zinc finger protein (AT5G24930), which has been predicted as target proteins for Cyt-gluRS by AtPIN, were also detected in the experimental screening.</p> <p>Conclusions</p> <p>AtPIN is a friendly and easy-to-use tool that aggregates information on <it>Arabidopsis thaliana </it>PPIs, ontology, and sub-cellular localization, and might be a useful and reliable strategy to map protein-protein interactions in Arabidopsis.

    How do Developers Improve Code Readability? An Empirical Study of Pull Requests

    Readability models and tools have been proposed to measure the effort to read code. However, these models are not completely able to capture the quality improvements in code as perceived by developers. To investigate possible features for new readability models and production-ready tools, we aim to better understand the types of readability improvements performed by developers when actually improving code readability, and identify discrepancies between suggestions of automatic static tools and the actual improvements performed by developers. We collected 370 code readability improvements from 284 Merged Pull Requests (PRs) under 109 GitHub repositories and produce a catalog with 26 different types of code readability improvements, where in most of the scenarios, the developers improved the code readability to be more intuitive, modular, and less verbose. Surprisingly, SonarQube only detected 26 out of the 370 code readability improvements. This suggests that some of the catalog produced has not yet been addressed by SonarQube rules, highlighting the potential for improvement in Automatic static analysis tools (ASAT) code readability rules as they are perceived by developers
