Pela construção de um estado de crítica: a reflexão crítica como campo dialógico

O texto aqui apresentado foi originalmente elaborado para o debate sobre a crítica de arte no I Congresso de Jornalismo realizado em São Paulo, pela Revista Cult, em Maio de 2009. Tendo como campo de trabalho a prática artística e a docência e envolvida no processo de formação de artistas desde 1982, meu objetivo foi argumentar a favor de um entendimento da crítica como dispositivo da arte e, portanto, atributo não só de críticos, mas também de artistas. Defendo a idéia da manutenção de um ‘estado de crítica' para o contexto brasileiro a partir de uma relação dialógica e internacionalizada, envolvendo também a fala crítica de artistas. Para isso reporto às práticas adotadas no século XX pelos artistas que colaboraram para inserir a obra de arte no campo programático da auto-crítica e da crítica ao sistema, evidenciando assim a posição destes como agente ativos no sistema

The chemiluminescent peroxyoxalate system: state of the art almost 50 years from its discovery

Almost fifty years after the discovery of the peroxyoxalate reaction by E. A. Chandross in the early nineteen sixties, this review article intends to give a general overview on mechanistic aspects of this system and to describe the principles of its analytical application. After a short general introduction on the principles of chemiluminescence and the history of peroxyoxalate discovery, mechanistic aspects of high-energy intermediate formation, its structure and its reaction with an activator in the peroxyoxalate system are discussed. Finally, analytical applications of peroxyoxalate chemiluminescence are exemplified using representative recent examples, including oxalic acid detection in biological samples.

The antioxidative effect of de novo generated vitamin B-6 in Plasmodium falciparum validated by protein interference

The malaria parasite Plasmodium falciparum is able to synthesize de novo PLP (pyridoxal 5'-phosphate), the active form of vitamin B-6. In the present study, we have shown that the de novo synthesized PLP is used by the parasite to detoxify O-1(2) (singlet molecular oxygen), a highly destructive reactive oxygen species arising from haemoglobin digestion. The formation of O-1(2) and the response of the parasite were monitored by live-cell fluorescence microscopy, by transcription analysis and by determination of PLP levels in the parasite. Pull-down experiments of transgenic parasites overexpressing the vitamin B-6-biosynthetic enzymes PfPdx1 and PfPdx2 clearly demonstrated an interaction of the two proteins in vivo which results in an elevated PLP level from 12.5 mu M in wild-type parasites to 36.6 mu M in the PfPdx1/PfPdx2-overexpressing cells and thus to a higher tolerance towards O-1(2). In contrast, by applying the dominant-negative effect on the cellular level using inactive mutants of PfPdx1 and PfPdx2, P. falciparum becomes susceptible to O-1(2). Our results demonstrate clearly the crucial role of vitamin B-6 biosynthesis in the detoxification of O-1(2) in P falciparum. Besides the known role of PLP as a cofactor of many essential enzymes, this second important task of the vitamin B-6 de novo synthesis as antioxidant emphasizes the high potential of this pathway as a target of new anti-malarial drugs.

The clinical impact of chromosomal rearrangements with breakpoints upstream of the SOX9 gene: two novel de novo balanced translocations associated with acampomelic campomelic dysplasia

Abstract Background The association of balanced rearrangements with breakpoints near SOX9 [SRY (sex determining region Y)-box 9] with skeletal abnormalities has been ascribed to the presumptive altering of SOX9 expression by the direct disruption of regulatory elements, their separation from SOX9 or the effect of juxtaposed sequences. Case presentation We report on two sporadic apparently balanced translocations, t(7;17)(p13;q24) and t(17;20)(q24.3;q11.2), whose carriers have skeletal abnormalities that led to the diagnosis of acampomelic campomelic dysplasia (ACD; MIM 114290). No pathogenic chromosomal imbalances were detected by a-CGH. The chromosome 17 breakpoints were mapped, respectively, 917–855 kb and 601–585 kb upstream of the SOX9 gene. A distal cluster of balanced rearrangements breakpoints on chromosome 17 associated with SOX9-related skeletal disorders has been mapped to a segment 932–789 kb upstream of SOX9. In this cluster, the breakpoint of the herein described t(17;20) is the most telomeric to SOX9, thus allowing the redefining of the telomeric boundary of the distal breakpoint cluster region related to skeletal disorders to 601–585 kb upstream of SOX9. Although both patients have skeletal abnormalities, the t(7;17) carrier presents with relatively mild clinical features, whereas the t(17;20) was detected in a boy with severe broncheomalacia, depending on mechanical ventilation. Balanced and unbalanced rearrangements associated with disorders of sex determination led to the mapping of a regulatory region of SOX9 function on testicular differentiation to a 517–595 kb interval upstream of SOX9, in addition to TESCO (Testis-specific enhancer of SOX9 core). As the carrier of t(17;20) has an XY sex-chromosome constitution and normal male development for his age, the segment of chromosome 17 distal to the translocation breakpoint should contain the regulatory elements for normal testis development. Conclusions These two novel translocations illustrate the clinical variability in carriers of balanced translocations with breakpoints near SOX9. The translocation t(17;20) breakpoint provides further evidence for an additional testis-specific SOX9 enhancer 517 to 595 kb upstream of the SOX9 gene.

Videocirurgia na criança: estado da arte. Experiência com 1408 procedimentos no Instituto da Criança "Pedro de Alcântara"

A videocirurgia em Cirurgia Pediátrica encontra um imenso campo de aplicações ainda, infelizmente, pouco explorado. São poucos os serviços que utilizam rotineiramente essa via de acesso e são escassas as referências nacionais publicadas. O Instituto da Criança do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo (ICr) há uma década e meia a utiliza e hoje a videocirurgia é a via de primeira escolha para tratar, entre outras doenças, o refluxo gastresofagiano, a colecistopatia calculosa, o testículo não palpável e o megaesôfago. Neste artigo relataremos a experiência em videocirurgia pediátrica do ICr, adquirida com 1408 pacientes operados, para divulgar e popularizar esta via de acesso, útil e benéfica para um grande número de situações e ainda subutilizada em Cirurgia Pediátrica.

Las grandes transparencias: Dada y surrealismo en los libros-collage de Julio Cortázar

The topic of this research is to demonstrate the technical and conceptual connections which can be seen between the style adopted by the Argentinean writer Julio Cortázar (1914-1984) in his “collage” books La vuelta al día en ochenta mundos (1967) and Último round (1969) and with the avant-garde art movements Dada and Surrealism.

The Presence of Words in Visual Art from Surrealism to Conceptualism

Without a doubt, one of the biggest changes that affected XXth century art is the introduction of words into paintings and, in more recent years, in installations. For centuries, if words were part of a visual composition, they functioned as reference; strictly speaking, they were used as a guideline for a better perception of the subject represented. With the developments of the XXth century, words became a very important part of the visual composition, and sometimes embodied the composition itself. About this topic, American art critic and collector Russell Bowman wrote an interesting article called Words and images: A persistent paradox, in which he examines the American and the European art of the XXth century in almost its entirety, dividing it up in six “categories of intention”. The aforementioned categories are not based on the art history timeline, but on the role that language played for specific artists or movements. Taking inspiration from Bowman's article, this paper is structured in three chapters, respectively: words in juxtaposition and free association, words as means of exploration of language structures, and words as means for political and personal messages. The purpose of this paper is therefore to reflect on the role of language in contemporary art and on the way it has changed from artist to artist.

The wine hedonic price models in the "Old and New World": : state of the art

The basic hedonic hypothesis is that goods are valued for their utility-bearing characteristics and not for the good itself. Each attribute can be evaluated by consumers when making a purchasing decision and an implicit price can be identified for each of them. Thus, the observed price of a certain good can be analyzed as the sum of the implicit prices paid for each quality attribute. Literature has reported hedonic models estimates in the case of wines, which are excellent examples of differentiated goods worldwide.The impact of different wine attributes (intrinsic or extrinsic) on consumers’ willingness to pay has been analyzed with dissimilar results. Wines coming from "New World" producers seem to be appreciated for different attributes than wines produced in the "Old World". Moreover, "Old and New World" consumers seem to value differently the wine’s characteristics. To our knowledge, no cross country analysis has been done dealing with "New World" wines in "Old World" countries, leaving an important gap in understanding underlying attributes influencing buying decisions.

Acerca de los procesos educativos en los movimientos sociales : contribuciones para un estado del arte sobre la cuestión

En este artículo nos proponemos ofrecer un panorama de las perspectivas teóricas utilizadas en los estudios recientes en nuestro país acerca de los procesos educativos de los movimientos sociales contemporáneos. Nos interesa identificar en cada caso 1os interrogantes y categorías centrales desde los cuales se aborda y problematiza el vínculo movimiento social-educación, entendiendo este ejercicio analítico abordado como un aporte a la elaboración de un estado del arte sobre la cuestión. Nuestra reflexión se apoya en los resultados de un relevamiento de distintas fuentes (comunicaciones en eventos científicos, libros y artículos de revistas), que requirió de una metodología específica para la codificación y análisis de los datos, inspirada en la propuesta de la investigadora brasileña Samira Kauchakje. Por ello, en la primera parte nos detenemos en los momentos y procedimientos involucrados en la elaboración de nuestro propio relevamiento, dando cuenta de los ajustes y criterios teóricos utilizados en la selección y análisis de los trabajos relevados, así como de las implicancias de todo lo anterior en la construcción del objeto de reflexión (las investigaciones sobre los procesos educativos señalados). Palabras clave: movimiento social, educación, investigación académica, metodología, relevamiento.

Estado, globalização e políticas educacionais : Mídia na Educação

O presente artigo tem como objetivo, verificar como as mídias na educaçao sao usadas pelo Estado. O Brasil, sendo um país em desenvolvimento, na aérea da educaçao passa por várias transformaçoes. Discussoes que partem desde o percentual do Produto Interno Bruto (PIB) para a educaçao até a discussao sobre a federalizaçao da educaçao. Com a globalizaçao, as políticas educacionais existentes, graças à modernidade técnica/tecnológica, passam por modificaçao. Porém, a globalizaçao pode deixar uma parcela da populaçao sem acesso a essas novas políticas educacionais, pois já que precisam de um novo suporte, alguns podem ser excluídos, mas se torna tarefa governamental levar essa nova forma de educaçao para todos, sem exclusao. Devemos buscar ampliar cada vez mais o acesso de todos à informaçao e as novas tecnologias, por uma política educacional democrática e aberta para todos os brasileiros, na forma da lei. Isso deve ser feito com seriedade, sem monopolizar informaçoes, e sociologicamente dizendo direitos e deveres de todos para com a formaçao de uma sociedade mais igualitária e justa. Assim, observamos um novo cenário, onde a globalizaçao avança, a tecnologia acompanha este crescimento, que deve ser acompanhado pelas políticas educacionais do Estado

Migrações para assentamentos rurais : Analisando as trajetórias de assentados no município de Padre Bernardo no Estado de Goiás Brasil

This work is the result of a case study that analyzes the trajectories of migrants to rural settlements located in the municipality of Padre Bernardo, the region surrounding the Federal District, Goiás State in this region several settlements created in the late 90's, were consisting of workers of rural origin who migrated from various regions of Brazil to work, especially in services and construction in Brasilia before reaching settlements. Thus, the text aims to give some reflections on understanding the dynamics of migration to rural settlements in Brazil trajectories with rural-city-settlements. As consideration, it was noticed that after many years or even decades living in the city, these migrants decide to join the struggle for land and depart for land occupation in the region. In the settlement, the settlers are facing a new challenge that will be built collectively and individually

El desarrollo rural y las contribuciones de la Psicología : Un estado de la cuestión

En todo el mundo, el 70 de la población pobre vive en áreas rurales. A pesar de los programas para revertir la pobreza, los resultados han sido limitados. El desarrollo rural busca reducir la desigualdad. Varios obstáculos que se les presentan a estos programas son psicosociales. El objetivo de este trabajo es explorar y describir las vinculaciones entre la Psicología y los procesos de desarrollo rural territorial en 111 publicaciones aparecidas entre 1985 y 2012. En la revisión, se encontró que los constructos utilizados fueron, entre otros, percepción, creencias, decisión, actitudes, participación y fortalecimiento. La Psicología puede realizar contribuciones al desarrollo rural territorial
