Повний текст джерелаBrazilian art from the 1970s is known for its high degree of experimentation and for challenging both artistic and museological canons. The annual exhibitions Panorama da Arte atual Brasileira and Jovem Arte Contemporânea, organized respectively by the Museum of Modern Art of São Paulo and the Museum of Contemporary Art of the University of São Paulo, are dedicated to exposing and legitimizing certain art trends during this period. The comparative analysis proposed by this research reveals and discusses the mechanisms of selection, organization, and presentation works in both exhibitions. The focus of the research takes place in 1972, when the show Jovem Arte Contemporânea presents major innovations and the Panorama discusses sculpture and object categories, the year is also marked by intense growth of the a São Paulo art market, the increase of military repression. We sought to examine the exhibitions within this larger context, taking as references the discussions that occurred in the international encounters of museums directors, and also other paradigmatic exhibitions for the period held in Europe and Latin America.

Повний текст джерелаMålet med denna rapport var att studera hur antalet myror som används av Ant Colony Optimization (ACO) påverkar resultatet vid lö- sandet av Traveling Salesman Problem (TSP). Hur ändras lösningens längd med olika antal myror, när antalet iterationer som får användas är begränsat? För att få fram ett svar på frågan implementerades och testades tre välkända ACO algoritmer: Min-Max Ant System (MMAS), Elitist Ant System (EliteAS) och Ranked Ant System (RankedAS). Efter implementering och utförlig testning så uppdagades trender som var konsistenta över flera testfall. För EliteAS och RankedAS, som bå- da förlitar sig på specialiserade myror, hade antalet specialister en stor påverkan på den funna längden. Normala myror hade istället en liten påverkan på slutresultatet. För MMAS och EliteAS så var skillnaden minimal, med en viss favör mot ett lägre antal myror. RankedAS hade en motsatt trend och hade bäst resultat med fem specialister och lika många normala myror som antalet städer i TSP instansen.

Повний текст джерелаField trials showed that combination applications of Advion and Top Choice provided the fastest and greatest reduction in foraging three days after treatment and the longest residual control of fire ant colonies for one year. Field tests documenting the impacts of Advion and Top Choice on non-target ants indicate treatments do supress ant foraging but ant populations will rebound 10-12 months after treatment.
Laboratory PCR assays revealed that colonies in Virginia are primarily polygyne. Also, Kneallhazia solenopsae, Pseudaction spp. parasitoid decapitating phorid flies, and Solenopsis invicta virues (SINV) genetic materials were detected in fire ant samples.
CLIMEX model results indicate that fire ants will be able to spread as far east as the Greater Richmond area and as far north as Alexandria in Virginia.

Повний текст джерелаNos observations montrent que le recrutement de groupe est lié à une forte motivation de certaines ouvrières à exploiter une source de nourriture découverte. Lorsqu’elles recrutent un groupe, elles passent peu de temps à l’intérieur du nid mais effectuent un taux élevé de contacts avec leurs congénères, principalement à l’entrée du nid, avant de repartir en direction de la nourriture, suivie par le peloton de fourrageuses. Durant le trajet, si une trajectoire rectiligne et une faible vitesse de déplacement favorisent la probabilité des recrutées d’atteindre la source, la perte de recrutées n’entraîne cependant aucune modification du comportement de la meneuse. Enfin, un suivi individualisé des fourrageuses au cours du recrutement montre que la probabilité d’être observée en tant que leader est répartie de manière homogène entre les individus découvrant la source de nourriture, sans influence du nombre de trajets qu’elles ont déjà effectués.
Par ailleurs, nous avons étudié l’influence des leaders sur les choix collectifs de la colonie. Les leaders modulent les caractéristiques du recrutement --fréquence des groupes, tailles des groupes-- en fonction des caractéristiques de la source exploitée. Grâce à un modèle multi--agents, nous avons démontré que cette modulation du recrutement permet à la colonie entière de focaliser son effort d’affourragement sur la nourriture la plus avantageuse lorsque plusieurs sources sont disponibles dans l’environnement. Enfin, nous avons développé un modèle mathématique décrivant le couplage du recrutement de groupe et du dépôt d’une piste chimique. Grâce à l’étude des états stationnaires de ce modèle, nous avons démontré que la présence des leaders est un élément indispensable à l’initiation de l’exploitation collective d’une ressource chez T. caespitum. Ainsi, les leaders de groupe permettent d’atteindre plus aisément un nombre seuil d’ouvrières à la source qui soit suffisant pour permettre l’émergence d’une piste chimique commune assurant à elle seule un recrutement de masse. Les résultats de cette thèse placent dans une nouvelle perspective notre vision des phénomènes de leadership chez les insectes sociaux. A l’échelle individuelle, ils mettent en évidence le statut temporaire de ces leaders chez Tetramorium caespitum basé sur leur propre motivation et les conditions locales du recrutement ;à l’échelle collective, ils soulignent le rôle complémentaire et facilitateur des leaders qui vont permettre l’émergence de structures auto-- organisées impliquant l’ensemble de la fourmilière.

Повний текст джерелаThe dynamics of the harvest is regulated by the coupling of a positive and negative feedbacks. The harvest acts as both: negative and positive feedbacks. Entering food-loads trigger foragers to exploit the newly discovered food source through the well-known recruitment process. At the same time, the harvest proportionally reduces the entering food flow until the complete stop of the foraging activity when the colony reaches satiety. Surprisingly, the positive feedback (that is the recruitment) is not responsible for a faster entering food flow and is not influenced by the colony needs while the exploring activity is. The spatial dynamics of the food exchange network revealed stable patterns and fine tuning regulation of the feeding process. Spatial analysis of the food distribution showed that sucrose is heterogeneously stored among individuals and also heterogeneously consumed. We observed a regular spatial structure leading to centralization of the stocks: heavy loaded individuals being at the center of the cluster and weakly loaded individuals at its periphery.
The spatiotemporal quantification of the food flow allowed describing and understanding the flexibility of the colony to adapt its working force according to its nutritional requirements.

Повний текст джерелаThis thesis is an ethnography of the ideias, practices, histories, memories, native theories, conflicts, inequalities, imaginations and experiences of Brazilian artists, critics, curators, art dealers and art collectors throughout the 1980s and 90s. The temporal and spacial breadth covered oscillates; we have, however, decided to focus the cities of Rio de Janeiro and São Paulo, and the intersection between the contemporary art circuit and its market through fieldwork done in galleries, museums, bienals, libraries, public and private archives, courses on art history, and testimonials. Between the many objects described, an emphasis is made on the international return to painting; the invention of the 80s generation and its relations to the market; the exhibitions Primitivism in the Twentieth Century (MoMA, New York, 1984) and Magiciens de la Terre (Centre Pompidou, Paris, 1989); the rediscovery of body, self and narrative during the 1990s; abject art and its main international exhibitions; the Anthropophagic Bienal of São Paulo (1998); the internationalization of Brazilian art in Europe, United States and Latin America; the trajectories and quarrels between different generations of art dealers in Brazil; the introduction of the entreprenurial and financial classes into cultural policies; and, above all, the status of Brazilian and Latin American art in a globalized context. From the Fluminense school of painting, through Brazilian Modernism, Neoconcretism, Tropicália, to the period emphasized in this work, the Brazilian artistic system and its characters have put a genuinely Brazilian art into question. Anthropophagy has been newly engaged as an alternative to euro-american power hierarchies and impositions, especially in the Anthropophagic Bienal of 1998. Nevertheless, when everyone is a cannibal, who cannibalizes whom? Oswald de Andrade or Montaigne? My hypothesis is the deformation of that matter, overcoming the problem of representation towards that of the presence, drawing on the deleuzian philosophy of the baroque experiments. Overcoming anthropophagy in benefit of the baroque is a way of inventing a different concept of creation, one that conceives the invention of difference through an exteriority in continued discontinuity, becomings, foldings that unfold, anthropophagy and regurgitophagy, inside and outside, figure and ground, interpretation and counter interpretation, framed art, and improvisation.

Повний текст джерелаIn this PHD Dissertation, I make a critical analysis of Brazilian artistic production in traffic of the 60 to 70 of the twentieth century, within the assumptions of feminist theories of cultural criticism, emphasizing the possibilities of female subjectivity by artistic practice. To be more specific, I am concerned here with some work done by thirty women artists working in this period, contemporary with each other and to the advent of the second feminism wave in the country, involving the aesthetic and plastic concerns in vogue, and that allow the approach of a feminist criticism, since they worki with body and identity issues, which mainly cover the limits and/or possibilities of subjective processes from the perspective of confrontations and subversions of the genre.

Resumo: Este trabalho propõe um estudo sobre atividade artística de Anita Malfatti dos anos de 1920, com o objetivo de analisar a inserção dessa produção no debate sobre arte moderna do período e o posterior reflexo desse debate nos principais estudos sobre o Modernismo no Brasil. Essa análise pressupõe uma reflexão sobre a recepção crítica em torno da obra da artista, desde a primeira apresentação ao público brasileiro, até a exposição individual realizada em 1929, que apresentou um panorama geral de sua produção artística. Considerando que a relevância de Anita Malfatti na história da arte brasileira está pontuada entre 1917 e a Semana de Arte Moderna, procuramos abordar as obras realizadas durante o estágio em Paris, entre 1923 e 1928, analisando o diálogo dessa produção com algumas discussões em pauta nesses anos: a relação com a Europa, o nacionalismo, o debate entre tendências mais radicais ou mais moderadas no contexto da arte moderna
Abstract: This study focuses on the artistic activity of Anita Malfatti in the 1920s. The main objective of this thesis is to analyze the relevance of her works in the modern art debate of the period, and the subsequent impact of this debate in the Modernism studies in Brazil. This analysis implies an understanding of the art criticism around her work, from the first presentation to the Brazilian public, until the exhibition held in 1929, which presented an overview of her artistic production. Whereas the relevance of Anita Malfatti in Brazilian art history is mostly discussed from 1917 to the exhibition of the Modern Art Week, this study deals with the paintings produced in Paris, between 1923 and 1928, by reflecting about their relations with modern art in Europe, nationalism in Brazil, and the debate between tradition and advanced art tendencies in the context of modern art

Повний текст джерелаThe research analyses the first fifteen editions of Habitat magazine: magazine of Brazilian art, in the period between October 1950 and April 1954. Of these fifteen editions, initially we investigated the characteristics that made the magazine so exceptional among all the other magazines of this same period the crucial input of Pietro Maria Bardi and Lina Bo, the magazines role as a modern cultural project, its connection with São Paulo´s Art Museum (MASP), the diversity of subjects covered in the magazine, its historical context and the fundamental participation of its collaborators. Secondly, we focused on the architecture shown in Habitat magazine, its selection, the values it expounded and the dialogue it had with international critics, that together, collaborated for the consolidation of modern architecture in the country.

Повний текст джерелаLasius neglectus visita principalmente árboles aislados donde permanece más meses atendiendo áfidos. Por el contrario, las hormigas nativas no visitaron los árboles según su ubicación (aislado, borde o centro del bosque). Excepto en el caso de la hormiga nativa Lasius grandis, que permaneció más tiempo en los árboles aislados cuando Lasius neglectus no estaba presente en el fragmento. La riqueza de especies nativas de hormigas y su visita a los árboles fue menor en fragmentos de bosque con Lasius neglectus. Crematogaster scutellaris, Temnothorax lichtensteini y Lasius grandis lograron coexistir con la hormiga invasora. La estructura de la comunidad de hormigas nativas en fragmentos con o sin Lasius neglectus mostró un patrón aleatorio.
Entre Mayo y Octubre, en las encinas se encontraron dos especies de áfidos, Hoplocallis picta, ocasionalmente atendido por las hormigas, y Lachnus roborisun un mirmecófilo obligado. En encinas visitadas por la hormiga invasora, se observó que la abundancia de Lachnus roboris tendió a duplicarse, como así también su producción de melaza, porcentaje de colonias atendidas comparado con los resultados obtenidos en encinas visitadas por la hormiga nativa Lasius grandis. Consecuentemente, durante el periodo estudiado la hormiga invasora duplicó su colecta de melaza por encina respecto de la hormiga nativa. Las colonias de Lachnus roboris se ubicaron principalmente sobre las bellotas. Sin embargo, no se detectó ningún efecto en la producción o calidad de bellotas y en la emergencia o calidad de las plántulas.
Ambas especies de hormigas capturaron principalmente Pscópteros y Hoplocallis picta como fuente de proteínas. El porcentaje de obreras que llevaba insectos o trozos de artrópodos entre sus mandíbulas fue superior para Lasius grandis.
La comunidad de artrópodos y el nivel de herbivoría no fueron modificados por la presencia de una u otra especie de hormiga. Sin embargo, en las encinas visitadas por Lasius neglectus las arañas, los curculiónidos y los áfidos tendieron a incrementar su abundancia mientras que las larvas de coccinélidos (predadores de áfidos) disminuyeron marcadamente.
La melaza que no es recogida por las hormigas puede incorporarse al suelo disuelta en el agua de trascolación de la copa como carbono orgánico disuelto (COD). La colecta de melaza de Lasius neglectus disminuyó el COD disuelto en el agua de trascolación de las encinas lo cual indicaría una interrupción del flujo de materia y energía entre la copa de las encinas y el suelo aledaño.
En relación a los efectos subsuperficiales se observó que el contenido de nutrientes en el suelo aledaño a las encinas visitas por Lasius neglectus fue mayor respecto del encontrado en encinas visitadas por hormigas nativas. Asimismo, la comunidad de microorganismos se diferenció según la presencia de hormigas nativas o de la invasora; tendiendo la biomasa microbiana del suelo a ser mayor en el caso de la presencia de Lasius neglectus. Según la localidad estudiada, la calidad de la hojarasca producida fue menor en los árboles visitados por Lasius neglectus. Sin embargo, la descomposición de la hojarasca de encina no fue modificada por la presencia de la hormiga invasora.
Se concluye que la presencia de Lasius neglectus modifica aquellos componentes, superficiales y subsuperficiales, del sistema de la encina que están directa o indirectamente relacionados con la colecta de melaza.
Invasive ants displace native ant species and other arthropods. As a consequence, at the invaded system biological interactions and ecological services provided by native ant species are modified. The aim of this study was to investigate some of the above-belowground effects of the invasive ant Lasius neglectus in an urban holm oak forest and to compare these effects with those of native ant species, in particular related to Lasius grandis.
Lasius neglectus mainly visited isolated trees where workers remained more months tending aphids and other insects. On the contrary, native ant tree visitation was not related to tree position in the fragments (isolated, edges or core trees). The only exception was the native ant Lasius grandis which remained more months at isolated trees in fragments where Lasius neglectus was not present. Native ant species richness and its tree visitation were lower at fragments where Lasius neglectus was present. Crematogaster scutellaris, Temnothorax lichtensteini y Lasius grandis were able to coexist with the invasive ant specie. Community structure of native ants did not differ from a random pattern with or without Lasius neglectus.
Some effects of the ant presence were investigated in detail at the holm oak (Quercus ilex) since this tree was the most abundant at the studied forest fragments.
Between May and October, two aphid species were found feeding at holm oak canopy: Hoplocallis picta, which was occasionally tended and Lachnus roboris which was the main tended species. At holm oaks visited by the invasive ant, the abundance of Lachnus roboris tended to increase twice, as well as their honeydew production related to results obtained at holm oaks visited by the native ant Lasius grandis. The percentage of tended colonies tended by Lasius neglectus was higher compared to the percentage tended by Lasius grandis. As a consequence, at the studied period, the invasive ant collected two fold of honeydew per tree related to the native ant. At holm oaks visited by Lasius neglectus or Lasius grandis colonies of Lachnus roboris fed mainly on acorn petiole or on their cap. However, there was not any difference of acorn production acorn or quality and sapling emergency or quality between these holm oaks.
Both ant species mainly captured Pscoptera and Hoplocallis picta as source of proteins. The percentage of workers carrying insects or pieces of arthropods in its jaws was higher for Lasius grandis.
Arthropod community and herbivory level was not modified due the presence of the invasive or the native ant. However, some particular groups showed differences of its abundance. At holm oaks visited by Lasius neglectus, spiders, weevils and aphids tended to increase its abundance while ladybird larvae (aphid predators) decreased markedly.
Honeydew production that was not collected by ants may reach the soil dissolved in throughfall as dissolved organic carbon (DOC). Honeydew collection by Lasius neglectus decreased DOC content in throughfall. This result suggests that the invasive ant interrupts the flux of energy and matter between canopy and the soil surrounding holm oaks.
In relation with belowground effects of Lasius neglectus soil nutrient content was higher beneath holm oaks visited by the invasive ant in relation to those trees visited by native ants. Soil microbial community was characterized by the presence of Lasius neglectus and microbial biomass tended to increase beneath holm oaks visited by this invasive ant. Depending on the study site, litter quality was lower at holm oaks visited by Lasius neglectus. Litter decomposition was not modified by the presence of the invasive ant.
I conclude that Lasius neglectus presence modifies those below-aboveground components of the holm oak system that are directly or indirectly related to honeydew collection.

Повний текст джерелаThis research rises from the verification of the somewhat frequent use of the imperative form in statements in contemporary art. The commands are inserted in the art work itself in the form of “texts” that function as “instructions as art”. The investigation is developed in an anachronic projection – from the most recent art towards conceptual art (1960’s and 70’s), attempting to point out what, in the case of artistic imperatives, could be an updating of procedures and past strategies. In order to do that, the research seeks two study cases: one regarding the exhibit Located work (Madrid) (2008), conceived by Joseph Kosuth, and the other about Estudos para espaço e tempo (1969-2001), by Cildo Meireles. The analysis discusses the discoursives disputes between political conceptualism and tautological conceptual art, indicating a current precariousness of concepts and narratives.

Повний текст джерелаThis dissertation is the result of a data collection, reflections and analysis on the three conceptual Operas made by the artist Jose Roberto Aguilar, realized in the seventies: Circo Antropofágico Cósmico Ambulante Latino Americano apresenta esta noite: A Transformação permanente do Tabu em Totem; Ópera do 3º mundo; As 3 lutas de samurai e os 25 metros de pintura contra os demonios que assolam a arte contemporânea brasileira. Under the perspectives of the conceptual art at that time it was selected some procedures and creative processes used by the artist. From this point of view were positioned topics of discussion, like: the critic of the critic, art and Magic, authors performance, and video media. Important themes at that time. The theme Antropofagia, recurring in the work of Aguilar, was approached in a poetic 13-minute video, where the artist through interviews and reading the manifesto anthropophagic shows his vision of anthropophagic world. The contribution that master degree is to reveal datas and some points of views about three Operas Aguilar, and to amplify the archives of the art from the 70\'s, to contemporary studies.

Abstract: The present work aimed to evaluate the efficiency of crude oils of Carapa guianensis Aubl. (crabwood), Elaeis guineensis Jacq. (African oil palm), Sesamum indicum L. (sesame), Ricinus communis L. (castor beans), Azadirachta indica Juss (neem), Theobroma cacao L. (cocoa), Anacardium occidentale L. (cashew nut) and crude extracts of Anacardium occidentale on leafcutting ants control, using Atta sexdens rubropilosa as model. Toxicity bioassays with ant workers were done using: 1) treatments by incorporation of crude oils or extracts in artificial diet and 2) treatments by topic application of crude oils or extracts on the ants pronotum. According to obtained results in toxicity tests, some crude oils and extracts were select to be incorporated in baits or applied by nebulization and tested on laboratory colonies. The crude oils or extracts more efficient on laboratory colonies control were tested on field grown up colonies. The obtained results in all toxicity tests permitted to select crude oils of C. guianensis, E. guineensis, S. indicum, R. communis, A. indica, A. occidentale and hexane, dichloromethane, ethyl acetate and methanol extracts of A. occidentale to be applied by nebulization and crude oils of E. guineensis, A. indica and A. occidentale to be incorporated in baits and tested on laboratory colonies. On laboratory colonies, the nebulization with crude oils of C. guianensis, E. guineensis, S. indicum, R. communis and A. indica didn't cause any effect on colonies. Therefore, these crude oils don't must be used to leaf-cutting ants control. However, crude oil and hexane, dichloromethane, ethyl acetate and methanol extracts of A. occidentale propitiated the extinction of colonies. The E. guineensis, A. indica and A. occidentale baits didn't any cause effect on colonies hence it follows that these baits don't must be used to leaf-cutting ant's control

Resumo: O presente trabalho teve como objetivo o estudo da evolução dos comportamentos de preparação do substrato, cuidado com a cria e cuidado com a rainha e alados em formigas cultivadoras de fungo. Estas formigas pertencem à tribo Attini, subfamília Myrmicinae, e ocorrem exclusivamente no continente americano. Esta tribo contém aproximadamente 230 espécies, porém pouco se conhece da biologia da maioria delas, graças ao fato de serem extremamente crípticas e de não apresentarem importância econômica, como as formigas cortadeiras, que são as mais estudadas. Foram utilizadas seis espécies, que representam bem os diversos níveis da filogenia da tribo: Acromyrmex disciger, Apterostigma pilosum, Mycetarotes parallelus, Myrmicocrypta sp., Trachymyrmex fuscus e Trachymyrmex sp. nov. Os comportamentos foram estudados em ninhos mantidos em laboratório, com o auxílio de micro-câmeras e um aparelho gravador de vídeo. Os comportamentos foram analisados, caracterizados e quantificados. Os resultados foram divididos em três capítulos de acordo com o tipo de comportamento. No capítulo sobre a evolução dos comportamentos de preparação do substrato foi observado que, basicamente, o processo evoluiu no sentido de aumentar a capacidade das operárias em decompor inicialmente o substrato. As espécies basais, A. pilosum, M. parallelus e Myrmicocrypta sp. apresentaram um processamento mais simples com um número menor de comportamentos e principalmente sem os comportamentos do tratamento químico, que é responsável pela fragmentação do substrato ao mesmo tempo em que ele é tratado com enzimas digestivas. As duas espécies do gênero Trachymyrmex apresentaram um processo mais complexo com grande participação do tratamento químico. Em A. disciger, que é uma cortadeira, há uma intensa especialização do sistema de castas para o aumento da eficiência... (Resumo completo, clicar acesso eletrônico abaixo)
Abstract: This work aims to study the evolution of the behaviors of substrate preparation, brood, queen and winged forms care in fungus growing ants. These ants are included in the tribe Attini, subfamily Myrmicinae, and occur exclusively in the american continent. This tribe contains approximately 230 species, but little is known about the biology of most of them, tanks to the fact that they show very cryptic habits and are not economically important, like the leaf cutting ants, which are the most studied. Six species were used in this work, which represent well all the levels of the phylogeny of the tribe: Acromyrmex disciger, Apterostigma pilosum, Mycetarotes parallelus, Myrmicocrypta sp., Trachymyrmex fuscus and Trachymyrmex sp. Nov. The behaviors were studied in laboratory nests, with a set of micro cameras and a video recording device. The behaviors were analyzed, characterized and quantified. The results were summarized and discussed in tree chapters, arranged by type of behavior. In the chapter about the evolution of the substrate preparation behaviors, basically it is assumed that this process evolved in order to develop the capacity of previously decompose the substrate by the workers. In the basal species, A. pilosum, M. parallelus and Myrmicocrypta sp. this process is very simple with a small number of behaviors and principally without the behaviors of chemical treatment, which are responsible for the fragmentation of the substrate as it is treated by with digestive enzymes. In the two species of the genus Trachymyrmex, the process became more complex and showed a greater participation of these behaviors. A. disciger, witch is a leaf cutting ant, showed an extensive specialization of physical castes in all the phases of the process which elevated it's efficiency. In the chapter about the evolution of the behaviors of brood care... (Complete abstract click electronic access below)

Resumo: Este trabalho ¿ uma investigação sobre a emergência do tema do corpo nas artes visuais da década de 1990 ¿ é composto de três capítulos. O primeiro parte da premissa de que a irrupção do corpo como um tema privilegiado na arte dos anos 1990 relaciona-se ao estabelecimento de uma crise. Ao examinar esta crise, através de uma análise dos debates levantados por alguns teóricos do corpo na contemporaneidade, o capítulo tece um panorama para a compreensão da arte do corpo produzida nos anos 1990. Já o segundo capítulo trata de como a emergência do corpo enquanto um ¿problema¿ na cultura contemporânea refletiu-se no campo das artes visuais. Além de analisar alguns artistas e exposições que obtiveram destaque internacionalmente nos anos 1990, o capítulo discute as teorias ou conceitos do ¿abjeto¿ e do ¿pós-humano¿, largamente empregados pela crítica na caracterização da arte do corpo do período. Já o terceiro e último capítulo examina a arte do corpo realizada no Brasil tendo como parâmetros o 25º Panorama de Arte Brasileira (1997) e o segmento Um e Outro da XXIV Bienal de São Paulo (1998). Duas das mostras periódicas de maior prestígio no país, o Panorama e a Bienal atestam a importância assumida pelo tema do corpo na arte brasileira dos anos 1990
Abstract: This work ¿ an inquiry into the emergence of the theme of the body in the visual arts of the 1990s ¿ is constituted by three chapters. The first is based on the premise that the irruption of the body as a privileged theme in the art of the 1990s is related to the establishment of a crisis. By examining this crisis, through an analysis of the debates raised by some contemporary body theorists, the chapter weaves a panorama for the comprehension of the art of the body produced in the 1990s. The second chapter then investigates how the emergence of the body as a ¿problem¿ in contemporary culture was reflected in the visual arts field. Besides analyzing some artists an exhibitions which gained prominence internationally in the 1990s, the chapter discusses the theories or concepts of the ¿abject¿ and the ¿post-human¿, largely employed in the characterization of the art of the body of the period. The third and final chapter then examines the art of the body produced in Brazil taking as parameters the 25th Brazilian Art Panorama (1997) and the One and Other segment of the 24th São Paulo Biennial. Two of the most prestigious periodical shows in the country, the Panorama and the Biennial demonstrate the importance gained by the theme of the body in the Brazilian art of the 1990s
