Caso sonho real : mídia e direitos humanos na desocupação do Parque Oeste Industrial em Goiânia

Dissertação (mestrado)—Universidade de Brasília, Centro de Estudos Avançados Multidisciplinares, Programa de Pós-Graduação em Direitos Humanos e Cidadania, 2015.Inspirado e situado em um campo interdisciplinar, este trabalho tem como objetivo analisar a cobertura realizada e o papel desempenhado pela imprensa e mídia goiana no processo do violento despejo de cerca de 14 mil pessoas da ocupação Sonho Real na cidade de Goiânia em 2005. Também objetiva analisar as relações da mídia com diferentes concepções de Direitos Humanos. Para fornecer embasamento e fundamentos para a pesquisa, seguiu-se um caminho de análise histórica e teórica que aponta a importância da imprensa na constituição e desenvolvimento das sociedades modernas e democráticas. Nesta análise, foram levantados alguns conceitos-chave para o trabalho assim como empreendeu-se uma leitura sobre o desenvolvimento e características do campo jornalístico. Com o intuito de se ter um panorama da realidade midiática nacional, foi feito um levantamento histórico da consolidação de um sistema midiático no país buscando estabelecer as relações políticas e econômicas em sua constituição. Como forma de subsidiar um dos objetivos do trabalho, foram feitas aproximações entre mídia e Direitos Humanos, assim como buscou-se através do diálogo com alguns autores estabelecer diferenças entre algumas concepções destes direitos. Na esteira da apresentação do caso Sonho Real e de algumas interpretações sobre o direito à moradia e direito à cidade, foi organizado no segundo capítulo a apresentação da pesquisa realizada com dois jornais de Goiânia, O Popular e Diário da Manhã, e a cobertura que realizaram em relação à ocupação Sonho Real. A análise dos materiais selecionados dos jornais foi feita baseada em uma metodologia com algumas categorias de análise que contribuíram para a obtenção de alguns resultados quantitativos e crítico qualitativos sobre o objeto e o caso estudado. Ao final, foi feita uma “amarração” crítica entre os referenciais teóricos e históricos levantados e os resultados da pesquisa com os jornais goianienses. Nesta fase, chegou-se a algumas conclusões que apontam a influência e relevância que a mídia teve não só na desocupação do Sonho Real, mas em todo o processo de legitimação das operações desempenhadas pelo Estado de Goiás, na formação de uma opinião pública favorável ao despejo, na criminalização dos sem-teto e na afirmação de uma concepção de direitos, democracia e Justiça alinhadas a uma perspectiva liberal de lei e ordem. Também constatou-se o alinhamento da mídia a uma concepção convencional ou hegemônica dos Direitos Humanos, ao passo que as ações do movimento sem-teto podem ser consideradas como localizadas em uma perspectiva contra-hegemônica deles. Fechando o trabalho, apresentou-se uma experiência diferenciada de cobertura midiática do caso realizada pelo Centro de Mídia Independente de Goiânia e alguns pontos sobre direito à comunicação e democratização da mídia, apontados como uma saída necessária.The analysis of the role of the media and the press during the process that culminated in the eviction of 14 thousand people from the Sonho Real occupancy in Goiânia (Goiás, Brazil) in 2005 is the main purpose of this interdisciplinary paper. It also aims to analyze the relations between media and the different conceptions in Human Rights. A historical and theoretical analysis followed in order to provide this research with the fundamentals and substance to point out how important the press is in the constitution and the development of democratic modern societies. This analysis undertook some key concepts and reading about the development and the main features in the journalistic field. A historical survey on the consolidation of a media system in Brazil aiming to determine both the economic and political relations in its constitution was made so that a panorama of the national media reality could be presented. As a way of sustaining one of this paper´s objective Media and Human Rights were brought together meanwhile the dialogue with some authors would establish some of the differences among the concepts of these rights. A presentation of the survey made from two newspapers from Goiânia, O Popular and Diário da Manhã, and their coverage about the Sonho Real occupancy was arranged in the second chapter right after the introduction of Sonho Real case and some interpretations of the right to housing and the right to the city. The analysis of the selected materials from both newspapers was based on a methodology with some analytical categories that contributed to some quantitative and critical qualitative results about the object and the referred case. Then, the historical and theoretical references collected previously and the results of the survey made from the newspapers from Goiânia were critically combined. At this point, some conclusions indicated how influential and relevant media was not only in the eviction of Sonho Real but also in the whole legitimating process of the operations led by the government of the State of Goiás through the formation of a public opinion favorable to the eviction, the criminalization of homeless people and the statement of a conception of democracy, Justice and rights aligned with a liberal perspective of law and order. An alignment of media with either a conventional or a hegemonic conception of the Human Rights was also noted, whereas the actions of the homeless movement can be considered to be under a counter-hegemonic perspective of them. In the end, a differentiated experience of media coverage of this case made by Centro de Mídia Independente de Goiânia (Indymedia) and some considerations about the right to communication and the media democratization were presented as a necessary breakthrough

Space-Efficient Representations of Raster Time Series

Financiado para publicación en acceso aberto: Universidade da Coruña/CISUG[Abstract] Raster time series, a.k.a. temporal rasters, are collections of rasters covering the same region at consecutive timestamps. These data have been used in many different applications ranging from weather forecast systems to monitoring of forest degradation or soil contamination. Many different sensors are generating this type of data, which makes such analyses possible, but also challenges the technological capacity to store and retrieve the data. In this work, we propose a space-efficient representation of raster time series that is based on Compact Data Structures (CDS). Our method uses a strategy of snapshots and logs to represent the data, in which both components are represented using CDS. We study two variants of this strategy, one with regular sampling and another one based on a heuristic that determines at which timestamps should the snapshots be created to reduce the space redundancy. We perform a comprehensive experimental evaluation using real datasets. The results show that the proposed strategy is competitive in space with alternatives based on pure data compression, while providing much more efficient query times for different types of queries.The data used in this study were acquired as part of the mission of NASA’s Earth Science Division and archived and distributed by the Goddard Earth Sciences (GES) Data and Information Services Center (DISC).

In-Vivo Real-Time Control of Protein Expression from Endogenous and Synthetic Gene Networks

We describe an innovative experimental and computational approach to control the expression of a protein in a population of yeast cells. We designed a simple control algorithm to automatically regulate the administration of inducer molecules to the cells by comparing the actual protein expression level in the cell population with the desired expression level. We then built an automated platform based on a microfluidic device, a time-lapse microscopy apparatus, and a set of motorized syringes, all controlled by a computer. We tested the platform to force yeast cells to express a desired fixed, or time-varying, amount of a reporter protein over thousands of minutes. The computer automatically switched the type of sugar administered to the cells, its concentration and its duration, according to the control algorithm. Our approach can be used to control expression of any protein, fused to a fluorescent reporter, provided that an external molecule known to (indirectly) affect its promoter activity is available

Efficient Estimation of the Robustness Region of Biological Models with Oscillatory Behavior

Robustness is an essential feature of biological systems, and any mathematical model that describes such a system should reflect this feature. Especially, persistence of oscillatory behavior is an important issue. A benchmark model for this phenomenon is the Laub-Loomis model, a nonlinear model for cAMP oscillations in Dictyostelium discoideum. This model captures the most important features of biomolecular networks oscillating at constant frequencies. Nevertheless, the robustness of its oscillatory behavior is not yet fully understood. Given a system that exhibits oscillating behavior for some set of parameters, the central question of robustness is how far the parameters may be changed, such that the qualitative behavior does not change. The determination of such a “robustness region” in parameter space is an intricate task. If the number of parameters is high, it may be also time consuming. In the literature, several methods are proposed that partially tackle this problem. For example, some methods only detect particular bifurcations, or only find a relatively small box-shaped estimate for an irregularly shaped robustness region. Here, we present an approach that is much more general, and is especially designed to be efficient for systems with a large number of parameters. As an illustration, we apply the method first to a well understood low-dimensional system, the Rosenzweig-MacArthur model. This is a predator-prey model featuring satiation of the predator. It has only two parameters and its bifurcation diagram is available in the literature. We find a good agreement with the existing knowledge about this model. When we apply the new method to the high dimensional Laub-Loomis model, we obtain a much larger robustness region than reported earlier in the literature. This clearly demonstrates the power of our method. From the results, we conclude that the biological system underlying is much more robust than was realized until now

Laguna Tordillo Formation: Eocene dacitic volcanism in the Deseado Massif, Santa Cruz province

Se determinó una nueva entidad formacional para la provincia geológica Macizo del Deseado. Se trata de rocas volcánicas melanocráticas que se presentan como dos afloramientos en inmediaciones de la laguna Tordillo, en el sector oriental del macizo del Deseado. Son lavas de color negro a rojizo, de textura porfírica con fenocristales de labradoritas (An55-57) inmersos en una pasta de textura hialocristalina, de tipo hialofítica. Además, poseen xenolitos de roca volcánica de textura glomeroporfírica con fenocristales de labradoritas (An56-59) y enstatitas (En56-Fs40-Wo4 ), con rebordes de reacción pigeoníticos (En44-Fs47-Wo9 ). Los análisis de elementos mayoritarios y traza las definen como lavas dacíticas, de tipo subalcalino y con afinidad calcoalcalina. Las relaciones estratigráficas evidencian una edad post-Jurásico superior, la cual fue confirmada mediante un fechado radimétrico K/Ar en roca total (fracción vidrio), que resultó en 40,8 ± 2,4 Ma (Eoceno). Teniendo en cuenta el marco paleogeográfico y geotectónico paleógeno para la Patagonia, se propone que estas rocas se generaron como consecuencia de un subplacado básico de magmas, posiblemente vinculados con el Basalto Cerro del Doce o unidades paleógenas correlacionables. Sin embargo, no se descarta una vinculación entre las rocas de la Formación Laguna Tordillo y las piroclastitas de la Formación o Grupo Sarmiento.A new formational entity for the Deseado Massif geological province was determined. They are melanocratic volcanic rocks presented as two outcrops in the proximity of the Tordillo lagoon, in the eastern Deseado Massif. They are black to reddish lava flows, with porphiritic texture composed by labradorite (An55-57) phenocrystals in a hialocrystalline, hialophitic texture matrix. They have also volcanic rock xenoliths with glomeroporphiritic texture composed by labradorite (An56-59) and enstatite (En56-Fs40-Wo4 ), with a pigeonitic rim (En44-Fs47-Wo9 ), phenocrystals. Majority and trace element analysis define them as subalkalic, with calc-alkaline affinities, dacite lavas. The stratigraphic relationships evidence an post-upper Jurassic age for these rocks; this was confirmed by a K/Ar whole rock (vitreous fraction) isotope determination, resulting in a 40.8 ± 2.4 Ma age (Eocene). Considering the Paleogene paleogeographic and geotectonic environment for Patagonia, it is proposed that these rocks were generated as a consequence of a basic magma underplating, possibly linked with the Cerro del Doce Basalt or correlated Paleogene units. Nevertheless, it is not discarded a link between the Laguna Tordillo Formation rocks and the Sarmiento Formation or Group pyroclastic rocks.Fil: Guido, Diego Martin. Universidad Nacional de La Plata.

The Bajo Pobre Formation Jurassic in the eastern Deseado Massif, Patagonia: Relationship with the Bahía Laura Group

Se describen nuevos afloramientos de la Formación Bajo Pobre hallados en el sector oriental del Macizo del Deseado, provincia de Santa Cruz, Patagonia Argentina. Esta unidad, junto con el Grupo Bahía Laura, corresponden al evento más importante magmático-piroclástico del Jurásico medio a superior del Macizo del Deseado. Se trata de lavas melanocráticas porfíricas a afaníticas, con fenocristales de plagioclasa, piroxeno y ocasional biotita, en una pasta de textura intersertal con microlitos de plagioclasa, piroxeno, opacos y en ocasiones con olivina. Las plagioclasas son de composición An53 a An85 (labradorita a bitownita) y los piroxenos son augita (Wo39 En48 Fs13), y pigeonita (Wo11 En54 Fs35) en los microlitos de las rocas con olivina (Fo51-45 Fa49-55). Son rocas intermedias a básicas, de composición andesita basáltica a andesita y con afinidades calcoalcalinas. Se describen lavas de la Formación Bajo Pobre con relaciones estratigráficas infra y suprayacentes respecto de rocas volcánicas ácidas del Grupo Bahía Laura. En las andesitas basálticas suprayacentes al Grupo Bahía Laura se obtuvo una edad K-Ar en roca total de 151,3 ± 3,4 Ma y para las andesitas infrayacentes se asume una edad Ar-Ar en plagioclasa de 177 ± 4 Ma. Estos estudios corroboran la extensión de los afloramientos de la Formación Bajo Pobre hacia la región costera del Macizo del Deseado y la combinación de las observaciones estratigráficas y geocronológicas confirman la relación de coetaneidad y posible intercalación entre las lavas de la Formación Bajo Pobre y las volcanitas ácidas del Grupo Bahía Laura, avalando la bimodalidad del magmatismo jurásico en el Macizo del Deseado.New Bajo Pobre Formation outcrops found in the eastern sector of the Deseado Massif, Santa Cruz province, Patagonia, are described. This unit, together with the Bahía Laura Group, is the most important magmato-pyroclastic event of the Deseado Massif. They are melanocratic, porphyric to aphanitic lava flows, with plagioclase, pyroxene and occasionally biotite phenocrysts in an intersertal matrix with plagioclase, pyroxene, opaque and occasionally with olivine microlites. Plagioclases are An53 to An85 (labradorite – bytownite) and pyroxenes are augite (Wo39 En48 Fs13), and pigeonite microlites (Wo11 En54 Fs35) in the rocks with olivine (Fo51-45 Fa49-55) microlites. They are intermediate to basic rocks, basaltic andesite to andesite in composition with calc-alkaline affinities. Underlying and overlying stratigraphic relationships of the Bajo Pobre Formation lava flows with the Bahía Laura Group acid volcanics are described. In the basaltic andesites overlying the Bahía Laura Group it was determined a 151.3 ± 3.4 Ma whole-rock K-Ar age and an assumed plagioclase Ar-Ar age of 177 ± 4 Ma for the underlying andesitic rocks. These studies confirm the extension of the Bajo Pobre Formation outcrops up to the Laura Group it was determined a 151.3 ± 3.4 Ma whole-rock K-Ar age and an assumed plagioclase Ar-Ar age of 177 ± 4 Ma for the underlying andesitic rocks. These studies confirm the extension of the Bajo Pobre Formation outcrops up to the coastal region of the Deseado Massif. The combination of stratigraphic observations and geochronology is in agreement with the coeval and possible interbedding relationship between the Bajo Pobre Formation lavas and the Bahía Laura Group acid volcanic rocks, supporting the bimodality of the Jurassic magmatism for the Deseado Massif.Fil: Guido, Diego Martin.

Age and petrography and geochemistry features of subvolcanic outcrops from Cerro León Formation, east of the Deseado Massif, Santa Cruz

Se presentan nuevos afloramientos de cuerpos subvolcánicos correlacionables con la Formación Cerro León en el sector oriental del Macizo del Deseado. Esta unidad aflora en dos sectores, en el bajo Leonardo y en el afloramiento Bahía Laura del Complejo Río Deseado. El primer sector presenta trece diques y un filón capa intruyendo a las sedimentitas pérmicas de la Formación La Golondrina y el segundo sector comprende tres diques que intruyen a rocas del basamento. Se trata de rocas de color gris a negro, frecuentemente alteradas, con textura microgranuda a porfírica, con fenocristales de plagioclasa, diópsido (En42 Fs11 Wo47) y en menor medida de hornblendas ricas en Mg (magnesio hastingsita), en una matriz holocristalina de textura intergranular. Son rocas subalcalinas de composiciones basalto-andesita y con afinidades calcoalcalinas. La edad Ar/Ar obtenida en una de estas muestras (180,1±1,5 Ma) representa la primer determinación realizada en esta unidad y es coherente con las relaciones estratigráficas observadas para esta formación. La comparación con rocas ígneas jurásicas de la provincia geológica Macizo del Deseado, favorece la vinculación temporal y genética con el evento volcánico-piroclástico del Jurásico medio a superior (Formación Bajo Pobre y Grupo Bahía Laura). Sin embargo, la diferencia en las edades Ar/Ar, sugieren una interrupción entre el evento subvolcánico (180 Ma) y el volcanismo Jurásico medio a superior (177 a 150 Ma). Se considera, preliminarmente, que los cuerpos subvolcánicos de la Formación Cerro León representarían las primeras evidencias magmáticas del rift jurásico en el Macizo del Deseado.New subvolcanic outcrops, correlated with the Cerro León Formation and located in the eastern Deseado Massif, are presented. This unit outcrops in two sectors, the Leonardo depression and the Bahía Laura outcrop of the Río Deseado Complex. In the first sector there are thirteen dikes and a sill intruding permian sedimentary rocks of the La Golondrina Formation and in the second sector, there are three dikes intruding the basement rocks. They are gray to black rocks, frequently altered, with microgranular to porphiritic texture, with plagioclase, diopside (En42 Fs11 Wo47) and Mg-rich hornblende (magnesio hastingsite) phenocrystals in a holocrystaline matrix with intergranular texture. They are subalkalic rocks, basalt-andesite in composition and with calc-alkaline affinities. The Ar/Ar age obtained from one of these rocks (180.1±1.5 Ma) represents the first determination on this unit and is coherent with the stratigraphic relationships observed in this formation. Comparison with jurassic igneous rocks from the Deseado Massif geological province, favor the temporal and genetic relationship with the middle to upper volcanic-pyroclastic event (Bajo Pobre Formation and Bahía Laura Group). Nevertheless, differences in Ar/Ar ages, suggest a gap between subvolcanic event (180 Ma) and the middle to upper Jurassic volcanism (177 a 150 Ma). It is proposed, preliminarily, that subvolcanic bodies from Cerro León Formation represent the first magmatic evidences of the Jurassic rift in the Deseado Massif.Fil: Guido, Diego Martin.

Impaired Fast-Spiking, Suppressed Cortical Inhibition, and Increased Susceptibility to Seizures in Mice Lacking Kv3.2 K+ Channel Proteins

Voltage-gated K(+) channels of the Kv3 subfamily have unusual electrophysiological properties, including activation at very depolarized voltages (positive to -10 mV) and very fast deactivation rates, suggesting special roles in neuronal excitability. In the brain, Kv3 channels are prominently expressed in select neuronal populations, which include fast-spiking (FS) GABAergic interneurons of the neocortex, hippocampus, and caudate, as well as other high-frequency firing neurons. Although evidence points to a key role in high-frequency firing, a definitive understanding of the function of these channels has been hampered by a lack of selective pharmacological tools. We therefore generated mouse lines in which one of the Kv3 genes, Kv3.2, was disrupted by gene-targeting methods. Whole-cell electrophysiological recording showed that the ability to fire spikes at high frequencies was impaired in immunocytochemically identified FS interneurons of deep cortical layers (5-6) in which Kv3.2 proteins are normally prominent. No such impairment was found for FS neurons of superficial layers (2-4) in which Kv3.2 proteins are normally only weakly expressed. These data directly support the hypothesis that Kv3 channels are necessary for high-frequency firing. Moreover, we found that Kv3.2 -/- mice showed specific alterations in their cortical EEG patterns and an increased susceptibility to epileptic seizures consistent with an impairment of cortical inhibitory mechanisms. This implies that, rather than producing hyperexcitability of the inhibitory interneurons, Kv3.2 channel elimination suppresses their activity. These data suggest that normal cortical operations depend on the ability of inhibitory interneurons to generate high-frequency firing
