A met��fora fundamental do discurso de John Dewey

This work aims to identify the rootmetaphor of John Dewey���s philosophical and educational discourse, by means of rhetorical analyses parameters. This methodology is founded in Aristotle and in the works of Cha��m Perelman and other contemporary authors involved in the revision of Aristotelian philosophy. The article examines the essays ���The philosophical work of Herbert Spencer��� and ���The influence of darwinism on philosophy���, published by John Dewey respectively in 1904 e 1909. They were written in the early years of Dewey in Columbia University, which intellectual environment was not dominated by Pragmatism, and for this reason they can be considered seminal in the structuring of the author���s arguments. The analysis reveals that Dewey is favorable to Darwinian evolutionism thesis and opposite to Spencer���s one. This positioning suggests that Dewey���s discourse is bound to the metaphor ���undetermined route��� because it situates evolution as a process devoid of previously listed purposes at a pre-determined plan, subject only to the relations that are established, so unpredictable, between organisms and the environmental conditions that surround. Analyzing Dewey���s ideas about education, the article concludes that ���undetermined route��� is the rootmetaphor of Dewey���s discourse, hypothesis that can contribute to discuss Dewey in the context of contemporary philosophy.

Canto e fala: o espet��culo do poder da linguagem na trag��dia grega

No presente estudo, destacamos como a estrutura da poesia tr��gica em partes cantadas e dialogadas resulta num grande espet��culo dominado pela palavra. Nos cantos corais e nos cantos de ator, os estados emocionais s��o marcados pelo vi��s da tradi����o do dialeto d��rico. Nos di��logos, o ritmo pr��ximo da fala quotidiana, em dialeto ��tico, acelera os acontecimentos em cena, p��e em a����o e movimenta o que Arist��teles depois vai chamar de ���a����o���. O resultado da mescla de tradi����o e novidade, de canto e fala, de dan��a e gestos, �� um espet��culo contendo mito e ���realidade���, poesia e ret��rica, entre outras dicotomias, em que o poder da linguagem �� colocado em cena. Na trag��dia, ent��o, a palavra em todos os seus modos de express��o �� o espet��culo a ser visto e ouvido. Assim, a trag��dia grega insere-se numa longa tradi����o iniciada pela poesia oral hom��rica e anuncia o estabelecimento da filosofia.

Paix��o, mito e formas de vida em textos publicit��rios

The passion, understood by Aristotle, as a contingency which causes a change in the essence of the subject, was object of research of the Greek philosopher as rhetorical strategy used by the speaker to touch its listeners. The greimasian semiotics, enlarging the concept of Aristotle���s passion, understands it as the soul states of a subject that can be gathered form the analysis of a text. Reflections towards the passion discursivization and its persuasion effects in advertisements lead us to establish the relationships between passion, myth and ways of life.

A Raz��o e o Sagrado: suas contribui����es filos��ficas para a dessacraliza����o da natureza

Este trabalho tem como objetivo mostrar como se efetuou, historicamente, atrav��s das id��ias dos fil��sofos Pit��goras, Parm��nides, S��crates, Plat��o, Aristóteles, Tom��s de Aquino, Francis Bacon, Descartes e Newton, a cis��o entre os dois modos de conhecimento, o racional e o sensorial e como foi constru��da a religi��o crist��, de onde se originaram seus principais elementos, a imortalidade da alma e a exist��ncia de Deus, que fundamentaram uma religi��o tipicamente antropoc��ntrica, contributiva para uma vis��o utilitarista da natureza. Entende-se que estas duas categorias s��o essenciais para se entender como a natureza passou a ser dessacralizada completamente pelo ser humano e como foram criadas as bases filos��ficas para a houvesse a domina����o dos homens sobre outros homens, postas em pr��ticas com o advento do capitalismo.

Considera����es hist��ricas sobre o infinito e alguns de seus paradoxos

This research aims to elucidate some of the historical aspects of the idea of infinity during the creation of calculus and set theory. It also seeks to raise discussions about the nature of infinity: current infinite and potential infinite. For this, we conducted a survey with a qualitative approach in the form of exploratory study. This study was based on books of Mathematics' History and other scientific works such as articles, theses and dissertations on the subject. This work will bring the view of some philosophers and thinkers about the infinite, such as: Pythagoras, Plato, Aristotle, Galilei, Augustine, Cantor. The research will be presented according to chronological order. The objective of the research is to understand the infinite from ancient Greece with the paradoxes of Zeno, during the time which the conflict between the conceptions atomistic and continuity were dominant, and in this context that Zeno launches its paradoxes which contradict much a concept as another, until the theory Cantor set, bringing some paradoxes related to this theory, namely paradox of Russell and Hilbert's paradox. The study also presents these paradoxes mentioned under the mathematical point of view and the light of calculus and set theory

Futebol, poesia e drama: o espet��culo

O que seria necess��rio para que se pudesse dizer que uma partida de futebol semelha de alguma forma a um espet��culo teatral, po��tico, emocional? O artigo prop��e um passeio livre pela hist��ria dos diferentes tipos de teatro e pelas mudan��as sofridas ao longo dos anos. A autora lembra que existe, da metade do s��culo passado para c��, uma n��tida divis��o que colocou em campos opostos o teatro dram��tico e o teatro ��pico, o drama rigoroso contra o texto quase absolutamente livre, Arist��teles contra Brecht. E volta a apresentar as raz��es pela qual se pode afirmar que existem certos momentos no futebol que o aproximam ainda mais do espet��culo teatral, da dan��a, da com��dia e do drama

Purification, characterization and structural determination of chitinases produced by Moniliophthora perniciosa

The enzyme chitinase from Moniliophthora perniciosa the causative agent of the witches' broom disease in Theobroma cacao, was partially purified with ammonium sulfate and filtration by Sephacryl S-200 using sodium phosphate as an extraction buffer. Response surface methodology (RSM) was used to determine the optimum pH and temperature conditions. Four different isoenzymes were obtained: ChitMp I, ChitMp II, ChitMp III and ChitMp IV. ChitMp I had an optimum temperature at 44-73��C and an optimum pH at 7.0-8.4. ChitMp II had an optimum temperature at 45-73��C and an optimum pH at 7.0-8.4. ChitMp III had an optimum temperature at 54-67��C and an optimum pH at 7.3-8.8. ChitMp IV had an optimum temperature at 60��C and an optimum pH at 7.0. For the computational biology, the primary sequence was determined in silico from the database of the Genome/Proteome Project of M. perniciosa, yielding a sequence with 564 bp and 188 amino acids that was used for the three-dimensional design in a comparative modeling methodology. The generated models were submitted to validation using Procheck 3.0 and ANOLEA. The model proposed for the chitinase was subjected to a dynamic analysis over a 1 ns interval, resulting in a model with 91.7% of the residues occupying favorable places on the Ramachandran plot and an RMS of 2.68.

Ecolog��a y estatus tr��fico del erizo de mar Diadema antillarum (Philippi, 1845) en los fondos rocosos de las Islas Canarias (Gran Canaria, Espa��a)

La explosi��n demogr��fica de erizo Diadema antillarum en los ecosistemas sumergidos rocosos del litoral canario est�� provocando una intensa desertizaci��n, generando los popularmente conocidos como fondos de ���blanquizales��� debido al color blanco que adquiere el recubrimiento calc��reo. Se analizaron los par��metros morfom��tricos, de densidad poblacional, ecolog��a tr��fica e interacci��n espec��fica de la especie de erizo D. antillarum (Philippi, 1845) durante los a��os 2005, 2006 y 2007 en los fondos rocosos de la isla de Gran Canaria, Islas Canarias, Espa��a. Se evaluaron cuatro blanquizales con diferente orientaci��n geogr��fica y con caracter��sticas bi��ticas y abi��ticas distintas, lo que permiti�� analizar el papel tr��fico de D. antillarum bajo diferentes condiciones; adem��s de la evaluaci��n de la biomasa de las especies algales halladas en los fondos rocosos donde habita la especie. El estudio hace un especial ��nfasis en la evaluaci��n de la distribuci��n, discriminaci��n y selecci��n de las diversas fuentes algales consumidas por Diadema antillarum a trav��s de un seguimiento de la asimilaci��n de los productores primarios por los consumidores, mediante el uso de los is��topos estables 13C y 15N Los resultados no mostraron una variaci��n estacional de la morfometr��a de D. antillarum. Sin embargo, si existe una variaci��n respecto al tama��o del erizo con la profundidad. La especie mostr�� una disminuci��n de su tama��o cuanto mayor era la profundidad. Asimismo los resultados exhibieron una correlaci��n negativa entre la densidad poblacional de D. antillarum y el tama��o del erizo. Hay una clara tendencia a hallar las tallas peque��as de erizos conforme aumenta la maduraci��n o desarrollo de los blanquizales. Se encuentran tallas menores cuando la densidad de erizos supera los 5 erizos ��� m-2. La mayor densidad promedio encontrada en este estudio fue de 12, 83 erizos ��� m-2 y la talla menor fue de un di��metro de caparaz��n menor a 2 cm y un ancho de la linterna de Arist��teles de 0,8 cm; la categor��a de di��metro de caparaz��n m��s abundante fue la comprendida en el rango de 3,5-5,4 cm. Las firmas isot��picas de la fuentes algales y del m��sculo de D. antillarum mediante el uso de modelos de mezcla permitieron concluir que en t��rminos generales el g��nero Laurencia result�� un constituyente principal en la dieta de D. antillarum en los diferentes blanquizales; los g��neros Colpomenia, Padina, Sargassum, Hypnea, y Jania son constituyentes importantes en la dieta de D. antillarum cuando habita en sustratos de blanquizales desarrollados (maduros), de la misma forma que Dictyota, Zonaria, Liagora, Lobophora, y Stypocaulon constituyen fuentes importantes en los blanquizales menos desarrollados (inmaduros), mostrando un alto grado de solapamiento de fuentes. D. antillarum present�� una asimilaci��n diferencial, independientemente de la disponibilidad del alimento. La dieta de D. antillarum refleja una composici��n algal espec��fica dependiendo de la etapa de maduraci��n del blanquizal El estudio proporciona una herramienta cuantitativa que permite separar ambientes diferentes - h��bitats que experimentan diferentes grados de perturbaci��n- a trav��s de la evaluaci��n de una asimilaci��n diferencial de las algas por parte de D. antillarum.
