Resumo Diante da intensa resistência à crítica pós-colonial dentro dos estudos brasileiros, este artigo procura organizar a discussão sobre o pensamento pós-colonial no Brasil, estruturando e situando qual seria o seu principal objeto de estudo. De acordo com o argumento desenvolvido ao longo do artigo, a experiência pós-colonial no Brasil é narrada hegemonicamente pelo intelectual nacional-ocidental (o artífice da dialética entre o local e o universal), que sempre atesta uma filiação à tradição ocidental ao mesmo tempo que afirma um desejo por demarcação da singularidade nacional, onde estaria positivada a diferença entre o país e o centro de poder ocidental. Mostro no artigo que esse modo nacional-ocidental de articular o pós-colonial reproduz profundas lógicas de colonialidade. A partir da crítica dessa razão nacional-ocidental, proponho uma outra estruturação do pós-colonial nos estudos brasileiros.

Abstract Given the intense resistance towards postcolonial critique within Brazilian Studies, this article intends to organize the discussion about the postcolonial thought in Brazil, structuring it and situating what would be its main object of study. According to the argument developed in this article, the postcolonial experience is narrated hegemonically by the national-occidental intellectual (the craftsman of the dialectics between the local and the universal). This intellectual frequently claims filiation to the Western tradition whilst also affirming the desire to demarcate the national singularity, turning positive the difference between his marginal country and the center of Western power. In this article I intend to show that the national-occidental way of articulating the postcolonial replicates the profound logic of coloniality. Based on this critique of the national-occidental reason, I offer an alternative structuration to the postcolonial question within Brazilian Studies.

Résumé Cet article vise à organiser la discussion sur la pensée post-coloniale au Brésil, vis-à-vis de l'intense résistance à la critique post-coloniale au sein des études brésiliennes, en structurant et en situant ce qui serait son principal objet d'étude. Selon l'argument développé tout au long de l'article, l'expérience post-coloniale au Brésil est racontée hégémoniquement par l'intellectuel national-occidental (l'artisan de la dialectique entre le local et l'universel), qui rend compte d'une affiliation avec la tradition occidentale en même temps qu'il affirme une volonté de démarcation de l'unicité nationale, dans laquelle la différence entre le pays et le centre du pouvoir occidental serait perçue comme positive. Je montre dans l'article que cette façon nationale-occidentale de penser le post-colonial reproduit les logiques profondes de la colonialité. Sur la base de la critique de cette raison nationale-occidentale, je propose une autre structure du post-coloniale au coeur des études brésiliennes.

Resumo: O artigo discute educação, estética e possibilidades para uma estética decolonial, a partir de uma vivência que denominamos mediação (inter)cultural em uma escola guarani e em uma exposição de arte na 10ª Bienal do Mercosul. A noção de escola (inserida no território indígena) como espaço de fronteira contribuiu para a compreensão de um pensamento fronteiriço, que escapa ao cânone moderno ocidental. A mediação (inter)cultural mostrou-se útil como método para o je guata - caminhada -, uma caminhada investigativa, realizada com um coletivo escolar pertencente ao povo guarani.

Abstract: This article discusses education, aesthetics and possibilities for a decolonial aesthetics, based on an experience we call (inter)cultural mediation in a Guarani school and an art exhibition at the 10th Mercosul Biennial. The concept of school (located in the indigenous territory) as a border space contributed to the understanding of a border thinking, which escapes the modern western canon. The (inter)cultural mediation proved to be useful as a method for je guata - a walking -, an investigative walking, performed with a school group of Guarani people.

Résumé: Cet article porte sur l’éducation, l’esthétique et les possibilités pour une esthétique décoloniale à partir d’une expérience de recherche de médiation (inter)culturelle dans une école guarani et dans une exposition d’art à la 10e Biennale du Mercosur. Dans le contexte indigène, l’école est un espace frontalier et pour nous, elle a contribué à la compréhension d’une pensée sur la frontière qui échappe au canon occidental moderne. La médiation (inter) culturelle s’est avérée utile comme méthodologie de recherche pour réfléchir sur la je guata - la marche -, une marche d’investigation, réalisée avec un collectif scolaire guarani.

The objective of this study was the evaluation of the use of different measures as predictors of breast weight. Thirty-two Anak chicks and 32 Ross chicks were used for the experiment 1. They were randomly sampled from two populations of 400 broilers of each genotype. A slaughter followed by dissection of commercial cuts was done at 53 days old. The following weights were recorded: live weight (PV), eviscerated carcass (PC), and breast (Pch). Proportions to live weight were also used (%PC, %Pch). Breast height and length were measured with calipers previously to the slaughter. Differences between genotypes were found for PV, PC, %PC, Pch and %Pch (p< 0.05). The Ross broilers were heavier than the Anak ones, as theirs carcasses, breasts and proportions were higher. Pch was high correlated with PV, and the calipers measurements did not improve the prediction of Pch and %Pch. Sixty INTA-Campero broilers, randomly sampled from 100, were used for the experiment 2 up to 69 days old. At that age in vivo calipers measures were taken from the length and height of the breast, and ultrasound was used for depth of breast measure. The measured characters at slaughter were the same as those of the experiment 1. An appropriate prediction of Pch was obtained using PV, breast length and breast depth (R²=0,75). The elimination of the ultrasound measurement did not reduce the model fit in an important way (R²=0,725).

El objetivo del presente trabajo fue evaluar la utilización de distintas mediciones como predictores del peso de la pechuga. En la experiencia 1 se utilizaron 32 pollos Anak y 32 pollos Ross, muestreados al azar de dos lotes de 400 animales de cada genotipo. A los 53 dias de edad se realizó la faena y una disección de cortes comerciales. Se tomaron los siguientes pesos: peso vivo (PV), de la canal (PC) y de la pechuga (Pch). Se calculó para el análisis la proporción de cada uno sobre el peso vivo (%PC y %Pch). También se midieron el largo y el ancho de la pechuga con calibre. Se observaron diferencias entre genotipos para PV, PC, %PC, Pch y %Pch (p <0,05). Los animales de la línea Ross resultaron más pesados que los Anak, así coma su carcasa, pechuga y proporciones resultaron mayores. La Pch se correlacionó alta y positivamente con el PV. Ninguna de las mediciones con calibre in vivo significó un aumento de consideración en la precisión de la predicción de Pch. En la experiencia 2 se utilizaron 60 pollos INTA-Camperos, muestreados al azar de un lote de 100 animales. A los 69 días de edad se realizaron mediciones in vivo del largo y ancho de la pechuga con calibre, y de la profundidad por ultrasonido previo a la faena, midiéndose los mismos parámetros que en la anterior experiencia. La correlación entre PV y la Pch fue alta y positiva, pero media a baja con las mediciones con calibre. Se obtuvo una buena predicción de Pch (R²=0,75) a partir del peso vivo, del largo y de la profundidad de pechuga. La eliminación de la medición ecográfica no redujo el ajuste del modelo de manera significativa (R²=0,725).
