O efeito do fim do Acordo sobre Têxteis e Vestuários para a indústria brasileira: uma análise a partir da fronteira de produção estocástica

This article investigates the productivity and production function of thirteen large Brazilian textile and clothing companies before and after the end of the Agreement on Textiles and Clothing (AVT) that abolished import quotas in 2005. For this purpose, we estimate the stochastic production frontier in panel data between 1997 and 2008 and simultaneously an explanatory equation for the (in)efficiency of firms, as proposed by Battese and Coelli (1995). The results indicated that more efficient firms are the oldest. The total factor productivity of firms tended to fall, even after the end of quotas, increasing productivity only from 2007. Overall, firms from Santa Catarina were more efficient than those of other states.

A corporeidade infantil edificada por tempos e espaços escolares

This paper has as its theme the relationship between child corporeity and school culture. The purpose is thus to discuss the school culture, in its dimensions to school times and spaces and to reflect on the influence of these dimensions in the construction of children corporeity who attending primary and the first grade of nine year elementary school.

Teoria crítica da sociedade: um olhar sobre a educação em tempos de sociedade tecnológica

This article aims to discuss and reflect on the contributions of the Critical Theory of Society called for the field of education in times of increasing technological development. Therefore, we look to the works of three authors exponents of Critical Theory: Walter Benjamin, Theodor W. Adorno and Herbert Marcuse, highlighting the reflections and analyzes of these authors and using them as input in the educational field. The selfreflective and self-education is conceived in its potential to overcome the conditions of domination that remain in our society increasingly technified and supposedly democratic. Thus, the educational praxis think it seems like something urgent and necessary to be broken with certain conditions that keeps our potential to barbarism.

Degradação de forças dos elasticos intermaxilares ortodônticos sintéticos

This study aimed to evaluate the force degradation of synthetic elastics over time using dynamic biomechanical tests in order to find clinical parameters of what size of elastic and frequency of exchange should be used in orthodontic therapy. It was used 240 elastics of Dental Morelli, sizes 1/8", 3/16", 1/4 "and 5/16", medium force, divided in four groups. In each group was measured forces at different times, from immediate to 72 hours after immersion in water at 37°C and incubated stretched to 600% of its initial inner diameter. Tensile tests were performed on a universal testing machine EMIC DL2000 submerged in distilled water maintained at 37°C. Data were analyzed using SPSS version 16.0, by the Analysis of Variance (One-Way) with Tukey´s post test. There was a greater increase in pattern of force decay of immediate measurement until 24 hours in all sizes of synthetic elastics, from which it was observed a decrease in force progressively smaller, with the exception of 5/16´´ elastic with a maximum force decay occurred at 12h. It was concluded that: the elastic synthetic Dental Morelli suffered significant force degradation over time, with reduction of approximately 70% of the initial force during 24 hours of stretching, followed by a progressively smaller decrease; the amount of stretch for a ideal force in intermaxillary therapies depends on the distance between the points of attachment of elastic, being necessary to consult the tables to choose the size, force and frequency of replacement.

Resistência ao cisalhamento de bráquetes fotopolimerizados com arco de plasma, LED e luz halógena utilizando diferentes tempos

This study evaluated in vitro the shear bond strength of brackets bonded with xenon plasma arc light, light-emitting diode (LED) and conventional halogen light using different curing times. Brackets were bonded to the buccal surface of 60 human maxillary premolars allocated to five groups. In groups 1 and 2, the resin was cured with the plasma arc for three and six seconds (s), respectively; in groups 3 and 4, the LED was used for five and ten s, respectively; and in group 5, the halogen light was used for 40 s. The specimens were stored in water for 24 hours and subjected to a shear force until bracket failure. The debonding pattern was classified according to the adhesive remnant index (ARI). The results were assessed by Anova and the SNK post-hoc test. No differences were detected among groups 2, 4 and 5, which showed higher averages than groups 1 and 3, which were not different between themselves. The ARI scores showed no differences among the three types of light sources in all times tested. Plasma arc and LED lights can be used with shorter curing times, within certain limits, than conventional halogen light for bonding orthodontic brackets, without decreasing bond strength.

Memorial do fim: as várias faces de Machado de Assis

Este artículo se centra en el análisis de la novela Memorial do fim: a morte de Machado de Assis (1991), de Haroldo Maranhão. Basándose en las formulaciones teóricas de Linda Hutcheon en su Poética del postmodernismo (1991), analizamos la reelaboración paródica de la biografía de Machado de Assis presente en la novela. Esta práctica paródica, que se caracteriza por su dualidad contradictoria de la continuidad y la transgresión, es la principal característica de la narrativa posmoderna en esta novela de Haroldo Maranhão.

Escola, seu fim e o ressurgimento da educação: o paradoxo da subjetividade no saber atual

O sistema educativo passa por um processo da institucionalização do saber. Qualquer forma de aprendizado que não seja subjetivado pelo “saber-escola” é automaticamente desacreditada, tudo isso em virtude da sacralização da escola e de sua demanda. Os colégios promovem uma educação doutrinária e alienante do projeto de vida da comunidade a que se destina, por isso há que enfatizar que estes possuem caráter disciplinador semelhante ao que ocorrem em instituições como as cadeias, manicômios. Através da apreensão do parco poder do saber nas mãos dos dirigentes institucionais, os alunos são transformados em “objetos-sujeito”, alvos de novas técnicas e ações que os desapropriam do direito de questionamento. Muitos autores – Paulo Freire, Ivan Illich, militaram em prol da emancipação das comunidades e de formas de aprendizagem autodirigidas e que promovessem a leitura e apreensão do mundo, efetivando troca de habilidades e o retorno das coletividades. São esses agentes políticos que norteiam essa revisão bibliográfica, de caracteres quiméricos para muitos, mas imprescindível para o retorno da educação que não se encontra apenas nas paredes da arquitetura panóptica dos locais instituídos como educacionais, mas sim em todas as situações que subjetivam os indivíduos ao longo de toda sua vida.
