Identidade e história: Belém do Grão-Pará como narrativa da nacionalidade

A motivação inicial desta pesquisa é a fértil discussão acerca da Identidade e das diferenças culturais entabulada especialmente pelos Estudos Culturais e Literários, especificamente a partir da categoria conceitual da nacionalidade. Norteada pelo conceito de Alegoria proposto por Fredric Jameson, para quem tal conceito se aplica principalmente à análise dos textos literários do capitalismo tardio, tentou-se desnudar as estratégias usadas na composição de Belém do Grão-Pará1 para narrar a complexidade da identidade nacional inscrita no Inconsciente Político. Admitindo que a Alegoria, para Jameson, é o próprio objeto cultural e estético cuja constituição e disposição dos elementos estruturais narra, às vezes em foro íntimo ou privado das personagens, a História das sociedades, segundo a experiência político-ideológica de suas classes. Tomados estes pressupostos, fez-se a análise do romance dalcidiano considerando-se a migração do protagonista como alegoria do cruzamento entre diferentes culturas, fato social gerador de uma hipotética diluição da identidade. Contudo, apoiado num paralelo traçado entre o contato do ribeirinho com o modus vivendi da cidade e a reação antropofágica do modernismo brasileiro frente ao modus vivendi civilizado da Europa, este trabalho nega a idéia de que o cruzamento de fronteiras culturais implique no fim da nacionalidade. Em linhas gerais tratamos de um conceito de Identidade fundado na experiência coletiva de indivíduos que, apesar de grandes diferenças de classe social, gênero ou etnia, construíram-se sob ideologias comuns. Nesta análise de Belém do Grão-Pará, cenas urbanas como ir ao cinema ou ver passar o trem são resignificadas pelo protagonista com base nas referências que trouxe de Cachoeira do Arari, seu lugar de origem, enquanto este também passa por uma revisão segundo o novo paradigma urbano que o protagonista vive em Belém.

Colagem, antropofagia e subversão em Galvez imperador do Acre, de Márcio Souza

O presente trabalho aborda o romance Galvez Imperador do Acre, publicado em 1976, pelo escritor amazonense Márcio Souza, estabelecendo as relações entre o texto literário e as propostas estéticas das vanguardas modernistas, tanto européias quanto brasileiras, propondo, assim, a investigação das relações entre modernismo e pós-modenismo, bem como as relações entre literatura, sociedade, história e cultura. Abordaremos questões como a ressignificação de textos literários ou não em Galvez imperador do Acre por meio do processo de colagem e intertextualidade, as relações entre o romance e o momento histórico que retoma e com aquele em que foi produzido, a operação de retomada do passado de forma crítica e transformadora e as possibilidades de leitura do texto literário com vista a algumas teorias pós-modernistas e pós-colonialistas. Observaremos, assim, a maneira como o mesmo retoma a Belle Époque e a extração do látex na Amazônia e sua estética fragmentária, constituída de diversas citações de autores canônicos, investigando o funcionamento da colagem e da antropofagia como principais ferramentas de denúncia e subversão ao processo cultural de importação de valores europeus vivido pelas capitais amazônicas no momento representado pelo romance e cuja crítica pode ser extrapolada para todo um processo de formação cultural no Brasil e na Amazônia. Para isso, poremos em causa as teorias de Jaques Derrida, Walter Benjamim, Claude Levi-Strauss, Fredric Jameson, Luiz Costa Lima, Antonio Candido, Aijaz Ahmad, Homi Bhabha, Stuart Hall, Canclini, Silviano Santiago, Angel Rama, Linda Hutcheon, Antoine Compagnon, entre outros, afim de, a partir do romance em análise, aprofundarmos a discussão teórica acerca das relações comparativas entre textos literários e entre os Estudos Literários e outros campos de estudo.

O cinema, o tempo social e o seu intérprete

By understanding art as a particular form of knowledge is possible to think that sociology has much to learn from it. One thesis that we share in this essay is that the art is able to perform the synthesis of the historical time for its specifi c capacity to be in the world, because, while scientifi c knowledge search universal categories, intending to reduce as much the infl uence of human and social aspects in the apprehension of phenomena, aesthetic knowledge, even if it seeks abstract referentials, can not get rid of the experience and the world around it. This premise, based on the reading of Fredric Jameson, worth as much to the art authorial as for the one performed in series, this is, the production of the cultural industry. Both one and another, in their own way, translates the social time, task that fi ts to criticism unravel.

Contradictio in terminis: dialéctica de la ambigüedad en la arquitectura contemporánea

The twentieth century brought a new sensibility characterized by the discredit of cartesian rationality and the weakening of universal truths, related with aesthetic values as order, proportion and harmony. In the middle of the century, theorists such as Theodor Adorno, Rudolf Arnheim and Anton Ehrenzweig warned about the transformation developed by the artistic field. Contemporary aesthetics seemed to have a new goal: to deny the idea of art as an organized, finished and coherent structure. The order had lost its privileged position. Disorder, probability, arbitrariness, accidentality, randomness, chaos, fragmentation, indeterminacy... Gradually new terms were coined by aesthetic criticism to explain what had been happening since the beginning of the century. The first essays on the matter sought to provide new interpretative models based on, among other arguments, the phenomenology of perception, the recent discoveries of quantum mechanics, the deeper layers of the psyche or the information theories. Overall, were worthy attempts to give theoretical content to a situation as obvious as devoid of founding charter. Finally, in 1962, Umberto Eco brought together all this efforts by proposing a single theoretical frame in his book Opera Aperta. According to his point of view, all of the aesthetic production of twentieth century had a characteristic in common: its capacity to express multiplicity. For this reason, he considered that the nature of contemporary art was, above all, ambiguous. The aim of this research is to clarify the consequences of the incorporation of ambiguity in architectural theoretical discourse. We should start making an accurate analysis of this concept. However, this task is quite difficult because ambiguity does not allow itself to be clearly defined. This concept has the disadvantage that its signifier is as imprecise as its signified. In addition, the negative connotations that ambiguity still has outside the aesthetic field, stigmatizes this term and makes its use problematic. Another problem of ambiguity is that the contemporary subject is able to locate it in all situations. This means that in addition to distinguish ambiguity in contemporary productions, so does in works belonging to remote ages and styles. For that reason, it could be said that everything is ambiguous. And that’s correct, because somehow ambiguity is present in any creation of the imperfect human being. However, as Eco, Arnheim and Ehrenzweig pointed out, there are two major differences between current and past contexts. One affects the subject and the other the object. First, it’s the contemporary subject, and no other, who has acquired the ability to value and assimilate ambiguity. Secondly, ambiguity was an unexpected aesthetic result in former periods, while in contemporary object it has been codified and is deliberately present. In any case, as Eco did, we consider appropriate the use of the term ambiguity to refer to the contemporary aesthetic field. Any other term with more specific meaning would only show partial and limited aspects of a situation quite complex and difficult to diagnose. Opposed to what normally might be expected, in this case ambiguity is the term that fits better due to its particular lack of specificity. In fact, this lack of specificity is what allows to assign a dynamic condition to the idea of ambiguity that in other terms would hardly be operative. Thus, instead of trying to define the idea of ambiguity, we will analyze how it has evolved and its consequences in architectural discipline. Instead of trying to define what it is, we will examine what its presence has supposed in each moment. We will deal with ambiguity as a constant presence that has always been latent in architectural production but whose nature has been modified over time. Eco, in the mid-twentieth century, discerned between classical ambiguity and contemporary ambiguity. Currently, half a century later, the challenge is to discern whether the idea of ambiguity has remained unchanged or have suffered a new transformation. What this research will demonstrate is that it’s possible to detect a new transformation that has much to do with the cultural and aesthetic context of last decades: the transition from modernism to postmodernism. This assumption leads us to establish two different levels of contemporary ambiguity: each one related to one these periods. The first level of ambiguity is widely well-known since many years. Its main characteristics are a codified multiplicity, an interpretative freedom and an active subject who gives conclusion to an object that is incomplete or indefinite. This level of ambiguity is related to the idea of indeterminacy, concept successfully introduced into contemporary aesthetic language. The second level of ambiguity has been almost unnoticed for architectural criticism, although it has been identified and studied in other theoretical disciplines. Much of the work of Fredric Jameson and François Lyotard shows reasonable evidences that the aesthetic production of postmodernism has transcended modern ambiguity to reach a new level in which, despite of the existence of multiplicity, the interpretative freedom and the active subject have been questioned, and at last denied. In this period ambiguity seems to have reached a new level in which it’s no longer possible to obtain a conclusive and complete interpretation of the object because it has became an unreadable device. The postmodern production offers a kind of inaccessible multiplicity and its nature is deeply contradictory. This hypothetical transformation of the idea of ambiguity has an outstanding analogy with that shown in the poetic analysis made by William Empson, published in 1936 in his Seven Types of Ambiguity. Empson established different levels of ambiguity and classified them according to their poetic effect. This layout had an ascendant logic towards incoherence. In seventh level, where ambiguity is higher, he located the contradiction between irreconcilable opposites. It could be said that contradiction, once it undermines the coherence of the object, was the better way that contemporary aesthetics found to confirm the Hegelian judgment, according to which art would ultimately reject its capacity to express truth. Much of the transformation of architecture throughout last century is related to the active involvement of ambiguity in its theoretical discourse. In modern architecture ambiguity is present afterwards, in its critical review made by theoreticians like Colin Rowe, Manfredo Tafuri and Bruno Zevi. The publication of several studies about Mannerism in the forties and fifties rescued certain virtues of an historical style that had been undervalued due to its deviation from Renacentist canon. Rowe, Tafuri and Zevi, among others, pointed out the similarities between Mannerism and certain qualities of modern architecture, both devoted to break previous dogmas. The recovery of Mannerism allowed joining ambiguity and modernity for first time in the same sentence. In postmodernism, on the other hand, ambiguity is present ex-professo, developing a prominent role in the theoretical discourse of this period. The distance between its analytical identification and its operational use quickly disappeared because of structuralism, an analytical methodology with the aspiration of becoming a modus operandi. Under its influence, architecture began to be identified and studied as a language. Thus, postmodern theoretical project discerned between the components of architectural language and developed them separately. Consequently, there is not only one, but three projects related to postmodern contradiction: semantic project, syntactic project and pragmatic project. Leading these projects are those prominent architects whose work manifested an especial interest in exploring and developing the potential of the use of contradiction in architecture. Thus, Robert Venturi, Peter Eisenman and Rem Koolhaas were who established the main features through which architecture developed the dialectics of ambiguity, in its last and extreme level, as a theoretical project in each component of architectural language. Robert Venturi developed a new interpretation of architecture based on its semantic component, Peter Eisenman did the same with its syntactic component, and also did Rem Koolhaas with its pragmatic component. With this approach this research aims to establish a new reflection on the architectural transformation from modernity to postmodernity. Also, it can serve to light certain aspects still unaware that have shaped the architectural heritage of past decades, consequence of a fruitful relationship between architecture and ambiguity and its provocative consummation in a contradictio in terminis. Esta investigación centra su atención fundamentalmente sobre las repercusiones de la incorporación de la ambigüedad en forma de contradicción en el discurso arquitectónico postmoderno, a través de cada uno de sus tres proyectos teóricos. Está estructurada, por tanto, en torno a un capítulo principal titulado Dialéctica de la ambigüedad como proyecto teórico postmoderno, que se desglosa en tres, de títulos: Proyecto semántico. Robert Venturi; Proyecto sintáctico. Peter Eisenman; y Proyecto pragmático. Rem Koolhaas. El capítulo central se complementa con otros dos situados al inicio. El primero, titulado Dialéctica de la ambigüedad contemporánea. Una aproximación realiza un análisis cronológico de la evolución que ha experimentado la idea de la ambigüedad en la teoría estética del siglo XX, sin entrar aún en cuestiones arquitectónicas. El segundo, titulado Dialéctica de la ambigüedad como crítica del proyecto moderno se ocupa de examinar la paulatina incorporación de la ambigüedad en la revisión crítica de la modernidad, que sería de vital importancia para posibilitar su posterior introducción operativa en la postmodernidad. Un último capítulo, situado al final del texto, propone una serie de Proyecciones que, a tenor de lo analizado en los capítulos anteriores, tratan de establecer una relectura del contexto arquitectónico actual y su evolución posible, considerando, en todo momento, que la reflexión en torno a la ambigüedad todavía hoy permite vislumbrar nuevos horizontes discursivos. Cada doble página de la Tesis sintetiza la estructura tripartita del capítulo central y, a grandes rasgos, la principal herramienta metodológica utilizada en la investigación. De este modo, la triple vertiente semántica, sintáctica y pragmática con que se ha identificado al proyecto teórico postmoderno se reproduce aquí en una distribución específica de imágenes, notas a pie de página y cuerpo principal del texto. En la columna de la izquierda están colocadas las imágenes que acompañan al texto principal. Su distribución atiende a criterios estéticos y compositivos, cualificando, en la medida de lo posible, su condición semántica. A continuación, a su derecha, están colocadas las notas a pie de página. Su disposición es en columna y cada nota está colocada a la misma altura que su correspondiente llamada en el texto principal. Su distribución reglada, su valor como notación y su posible equiparación con una estructura profunda aluden a su condición sintáctica. Finalmente, el cuerpo principal del texto ocupa por completo la mitad derecha de cada doble página. Concebido como un relato continuo, sin apenas interrupciones, su papel como responsable de satisfacer las demandas discursivas que plantea una investigación doctoral está en correspondencia con su condición pragmática.

Improving the recovery of coarse coal particles in a Jameson cell

It has been observed in several Jameson cell installation where the source for flotation feed is deslime screens, that the recovery of coal particles greater than 0.5 mm is not as great as that of finer material. Consequently, a research project was undertaken at a CHPP in the Bowen Basin Queensland to assess the possibility of increasing the recovery of coarser particles (+0.5 mm) within the downcomer of the Jameson cell. The effect of decreasing turbulence and agitation in a commercial-scale downcomer was investigated to assess the effect oil the recovery of both coarse and fine coal particles. This paper details the findings of the test work, summarising the results relating to differences in the operating parameters within the downcomer. (C) 2005 Elsevier Ltd. All rights reserved.

The history of theory

Do you see now why it feels so good to be a critical mind? Why critique, this most ambiguous pharmakon, has become such a potent euphoric drug? You are always right! When naïve believers are clinging forcefully to their objects ... you can turn all of those attachments into so many fetishes and humiliate all the believers by showing that it is nothing but their own projection, that you, yes you alone, can see. But as soon as naïve believers are thus inflated by some belief in their own importance, in their own projective capacity, you strike them by a second uppercut and humiliate them again, this time by showing that, whatever they think, their behavior is entirely determined by the action of powerful causalities coming from objective reality they don't see, but that you, yes you, the never sleeping critic, alone can see. Isn't this fabulous? Isn't it really worth going to graduate school to study critique?

Applications of the Jameson cell at the head of base metal flotation circuits

The Jameson Cell is a high intensity flotation device, which utilises induced air from the atmosphere. It was developed jointly by Mount Isa Mines and Professor Graeme Jameson of the University of Newcastle in the 1980s. It is proven to generate fine bubbles, in the order of 300 to 500 µm, in a high intensity, high shear and compact zone contained in the downcomer. This aerated mixture exits the downcomer into the pulp zone, which is the quiescent mineral and gangue separation zone. A number of Australian base metal flotation circuits feature a reverse flotation stage at the head of the circuit. Testwork and plant operating data has shown that the use of a Jameson Cell in the prefloat cleaner application has further improved prefloat gangue recovery and selectivity. Operation of a Jameson Cell in a carbonaceous/pyrite prefloat cleaner duty at the Mt Isa copper concentrator increased copper recovery and reduced pyrite in the copper concentrate. Testwork at Zinifex Century Zinc Mine showed a decrease in zinc losses by the utilisation of Jameson Cell prefloat cleaner. Appraisal of a Jameson Cell in a scalping role within the Mt Isa Copper Concentrator indicated significant benefits could be achieved.

O teatro de Elias Canetti em diálogo com a pós-modernidade

The purpose of this dissertation is to analyse the dramaturgic work of the Bulgarian author Elias Canetti, composed by the plays The Wedding, Comedy of Vanity and Their Days are Numbered, seeking to comprehend how the contemporary critic theories act on his trilogy, making a dialogue with theoretical references which may justify its approaching to the postmodernism. In this perspective, the theories by Jean-François Lyotard, Fredric Jameson and Jürgen Habermas contribute for a better comprehension of the postmodernity phenomenon. Undertaking Canetti’s notes and theatre with the philosophical concepts of Adorno’s negative aesthetics, we realise there is a space to reflect upon the theories which befell, like Foucault’s power relations in Micro-physics of Power and the discourses of resistance and deterritorialisation developed by Deleuze and Guattari in A Thousand Plateau and Anti-Oedipus. Even though Canetti’s plays were written between 1932 and 1956, all of them show a strong critic against modernism, and their characteristics did not help their recognition by the critics, which resulted in a rediscovery of Canetti’s plays after the author won the Nobel Prize in 1981.
