Desenvolviment(ism)o, descolonialidade e a geo-história da administração no Brasil: a atuação da CEPAL e do ISEB como instituições de ensino e pesquisa em nível de pós-graduação

O objetivo desta tese é investigar a atuação da Comissão Econômica para a América Latina (CEPAL) e do Instituto Superior de Estudos Brasileiros (ISEB) na história da educação em administração no Brasil. Esta tese partiu de uma metodologia historiográfica consolidada na área, mas utilizou a abordagem descolonial para problematizar o termo história e, assim, propor uma nova agenda de pesquisa. A importação de temas de pesquisa historiográfica como americanização e Guerra Fria provoca um mimetismo de agendas de investigação e termina por subalternizar outros eventos locais que contribuíram para a historiografia da administração. A investigação geo-histórica desta tese é feita a partir da interação entre dois conceitos de desenvolviment(ism)o – o que emerge a partir da realidade da América Latina e o que é recebido de fora via americanização – que ora se aproximam, ora se afastam, e que estão inseridos na long durée da modernidade/colonialidade da América Latina. A busca pela ciência da administração se iniciou, no Brasil, vinculada ao processo de modernização e desenvolvimento do país, que levou à criação, durante a década de 1950, das primeiras escolas de ensino de graduação em administração e dos cursos objetos desta tese, que formaram 1.316 profissionais em nível de pós-graduação. Neste período deve ser minimizado o papel da americanização e relativizada a atuação destas escolas de ensino de graduação na geo-história da administração. Devemos, portanto, descolonizar a atuação da CEPAL e do ISEB como instituições de ensino e pesquisa para trazer à tona conhecimentos da tradição do pensamento social crítico latino-americano que foram subalternizados na literatura de administração, para que possam informar a área no Brasil e no exterior. Este é um caminho para descolonizar a agenda de pesquisa historiográfica e escapar da tendência de reproduzir acriticamente conhecimento recebido do exterior.

A reafirmação do bairro:um estudo geo-histórico do bairro do Alecrim na cidade de Natal-RN

By the end of the 21st Century, economy globalization trends to show a velocity process through which market being expanded characterized by an intense going on of the internationalization of finance, after that marginalizing the periphery of the social spaces. It is clear to see that this process occurred in those less developed countries happens in an accentuated way just because income distribution that is so regressive and also because the insufficient enclosing of the social programs, we find this situation in a big part of Brazilian cities. The marginalizing social economical process observed in Natal, a city located in the east coast part of Northeast region in Brazil and that owns a population upper to 778 thousand in habitants is nearly linked to the extension of goods and services commerce. The installation of new urban activities in the city pointed out tourist activity as the greater impulsive thing in the phenomenon promotion, most of them aiming to promote Natal to the national and international scenery. It privilege strongly in the South zone with economical implementations such as shopping s centers, supermarkets, and home buildings condominiums leading to a loss of functionality of some traditional district located in central areas of the city. Notwithstanding, some spaces, for instance Alecrim district officially created in 1911, has notably resisted to the expansion of the urban process pointed out in Natal in the last years. So that this put Alecrim District as a district with originally characteristics reaffirmed along the historical process form old times. The predominance of some residential characteristics such as the incidence of some villages and a concentration of a big and confuse popular commerce distributed along streets puts Alecrim District as a resistant space in Natal. The same way analyze Alecrim District under the prism of Historic Geography because we understand this way it accomplishes a fundamental role in the theoretical methodological development of our work, just when we analyze the time as a variant in our object of study. It is still inside this theoretical field that we carry out a brief reviewing about quarter/district definition, under the optic from several registered and scientific resources taken into account along this work, because we understand that it was necessary to think this important spatial unit especially to know exactly what we are referring to as a district and so we can reaffirm Alecrim as an important and traditional district to Natal and it has been resisting to spatial transformation verified in the last years in Natal city. To give support to our reflection we used methodological tools related to inhabitants lifestyles knowledge and also the study of Alecrim District as a space that promote a certain centrality in Natal as some indicators to keep original characteristics in the district in Natal

Integrating geo-referenced multiscale and multidisciplinary data for the management of biodiversity in livestock genetic resources

P>In livestock genetic resource conservation, decision making about conservation priorities is based on the simultaneous analysis of several different criteria that may contribute to long-term sustainable breeding conditions, such as genetic and demographic characteristics, environmental conditions, and role of the breed in the local or regional economy. Here we address methods to integrate different data sets and highlight problems related to interdisciplinary comparisons. Data integration is based on the use of geographic coordinates and Geographic Information Systems (GIS). In addition to technical problems related to projection systems, GIS have to face the challenging issue of the non homogeneous scale of their data sets. We give examples of the successful use of GIS for data integration and examine the risk of obtaining biased results when integrating datasets that have been captured at different scales.

Near-infrared third-order nonlinearity of PbO-GeO(2) films containing Cu and Cu(2)O nanoparticles

We report measurements of the nonlinear (NL) refractive index n(2) of lead-germanium films (LGFs) containing Cu and Cu(2)O nanoparticles (NPs). The thermally managed eclipse Z-scan technique with 150 fs pulses from a laser operating at 800 nm was used. The NL refractive index measured, n(2)=6.3x10(-12) cm(2)/W has electronic origin and the NL absorption coefficient alpha(2) is smaller than 660 cm/GW. The figure of merit n(2)/lambda alpha(2) is enhanced by more than two orders of magnitude in comparison with the result for the LGFs without the copper based NPs.

Discriminating among earth composition models using geo-antineutrinos

It has been estimated that the entire Earth generates heat corresponding to about 40 TW (equivalent to 10,000 nuclear power plants) which is considered to originate mainly from the radioactive decay of elements like U, Th and K, deposited in the crust and mantle of the Earth. Radioactivity of these elements produce not only heat but also antineutrinos (called geo-antineutrinos) which can be observed by terrestrial detectors. We investigate the possibility of discriminating among Earth composition models predicting different total radiogenic heat generation, by observing such geo-antineutrinos at Kamioka and Gran Sasso, assuming KamLAND and Borexino (type) detectors, respectively, at these places. By simulating the future geo-antineutrino data as well as reactor antineutrino background contributions, we try to establish to which extent we can discriminate among Earth composition models for given exposures (in units of kt · yr) at these two sites on our planet. We use also information on neutrino mixing parameters coming from solar neutrino data as well as KamLAND reactor antineutrino data, in order to estimate the number of geo-antineutrino induced events. © SISSA/ISAS 2003.

Geo(anthropo)genic factors affecting the radioactivity in groundwaters from Guarani aquifer, Brazil

This investigation was carried out within the Paraná sedimentary basin, involved the sampling of 77 pumped tubular wells, and was realized with the puipose of evaluating the radioactivity in the Brazilian part of Guarani (Botucatu-Pirambóia, Tacuarembó, Misiones) aquifer. The radioactivity due to nuclides belonging to uranium and thorium series decay was investigated in terms of the uranium isotopes 234U and 238U, radon (222Rn), and the radium isotopes 226Ra and 228Ra. The obtained results were compared with the maximum permissible concentration limits in drinking water defined by the Brazilian national standard, as well with the guidelines for drinking water quality established by the World Health Organization. The importance of water-rock/soil interactions was considered in order to explain most of the obtained data.

Resistivity piezocone for geo-environmental site characterization: Two case histories from Brazil

This paper presents two case histories from Brazil where geophysical and resistivity piezocone tests were carried out to detect contamination. At the first one, the site investigation program was carried out to detect salt-water intrusions in a superficial sedimentary aquifer, at the Paranaguá harbor, in Paraná State. The second case history is a sanitary landfill from Bauru City, São Paulo State. In both sites, superficial geophysical tests were interpreted to detect and delineate the shape of contamination plume, helping to locate the resistivity piezocone tests. It was found that the interpretation of resistivity piezocone tests is straightforward to assess salt-water intrusion in sedimentary sands. For tropical soils, this technique presented some limitations since the groundwater table sometimes is deeper than the layer penetratable to the cone. Moreover, the genesis of those soils affects soil behavior and soil and water sampling is required to support interpretation.

Geo-environmental investigation: A brief review and a few suggestions for brazilian contaminated sites

This paper presents a brief review about site investigation procedures for contaminated sites recommended by Brazilian and Canadian environmental agencies as well as discusses the theme of geo-environmental investigation as applied to Brazilian practice. The main definitions on the theme are reviewed and some guidelines are proposed for conducting a geo-environmental investigation of Brazilian contaminated sites using different site and laboratory investigation techniques based on the presented review and on the experience obtained from the investigation of a solid waste disposal site in the interior of the state of São Paulo, Brazil.

The resistivity piezocone for high resolution geo-environmental site investigation: A Brazilian example

A suit able decision-making on managing a contaminated site characterization program is strongly dependent of the diagnosis process. A detailed diagnosis can be done based on a Conceptual Site Model (CSM) elaboration using high resolution site characterization tools. The piezocone (CPTu) test is a high resolution tool which allows attaching several specific sensors, like the resistivity probe. This hybrid device is called the resistivity piezocone (RCPTu). A simulated geo-environmental site characterization program was performed on an erosion site using different tools (direct push tools soil samplers, hollow stem auger (HSA) drilling and RCPTu tests) to develop the CSM for a site similar to the Brazilian conditions. It was observed a good agreement between the site profiles interpreted by the different methods. The resistivity sensor attached to the piezocone improved the interpretation and the decision-making process on site was significantly better for the CSM elaboration. The RCPTu test data also allowed identifying the hydrogeological heterogeneities. The present study shows that the RCPTu test is also a useful and powerful tool to development an accurate CSM in a Brazilian condition, especially in an approach that prioritizes high resolution geo-environmental investigation. © 2013 Taylor & Francis Group.

Distribuição geo-sociolinguística do ditongo 'ej' no português falado no estado do Pará

Este trabalho tem por objetivo apresentar os resultados de um estudo sobre a simplificação do ditongo decrescente /ej/ no português falado no Estado do Pará, localizado ao Norte do Brasil, com base nos pressupostos teórico-metodológicos da Sociolingüística Variacionista e da Geografia Linguística. Trata-se, portanto, de uma abordagem Geo-Sociolingüística, a qual relaciona fenômenos lingüísticos a comportamentos sociológicos e geográficos, que impõem e são impostos por normas específicas nas mais diversas manifestações da vida em sociedade. O corpus que se utilizou para a análise foi levantado a partir de questionários do Projeto Atlas Lingüístico do Brasil (ALiB), e está composto de entrevistas aplicadas a informantes previamente selecionados por meio de critérios também definidos a priori. Foram utilizados três questionários – QFF (Questionário Fonético-Fonológico), QSL (Questionário Semântico-Lexical) e QMS (Questionário Morfossintático) – além de perguntas sobre questões de pragmática, discurso semi-dirigido e texto reproduzido via leitura. Todo esse material foi elaborado pela equipe do projeto ALiB e aplicado por diretores científicos e suas respectivas equipes. Abrange a transcrição grafemática de todo o corpus e fonética do QSL e QFF, além da triagem dos itens lexicais continentes do ditongo supracitado que o corpus apresentou, para que estes pudessem ser submetidos à análise probabilística do programa computacional VARBRUL. Obtidos os resultados estatísticos, buscou-se interpretar os dados à luz das pesquisas já apresentadas sobre a variável no Brasil, além daquelas que serviram de base às problematizações acerca do fenômeno em língua portuguesa. Com base nessa interpretação, verificamos que, do ponto de vista lingüístico, o ditongo /ej/ apresenta restrições estruturais à sua realização plena; e que, do ponto de vista extralingüístico, há uma significativa distribuição dessas realizações no Estado ora pesquisado, que parece estar pautada em fatores dialetológicos, mas pouco relacionada a fatores sociais, exceto o fator escolaridade, que se mostrou relevante na aplicação da regra de monotongação ou na manutenção da semivogal do ditongo na fala do paraense.

Estudo da estrutura geo-elétrica da Região do Juruá, AM, pelo método magnetotelúrico

Utilizando-se dados magnetotelúricos (MT), foi obtida uma imagem geo-elétrica nítida da região do Juruá, Bacia do Solimões, na forma de seções geo-elétricas. Os dados de campo foram registrados ao longo de três linhas de 15 km, espaçadas de 3.5 km, recobrindo uma área de 100 km². O espaçamento entre as 35 estações é irregular, variando de 400 m a 3500 m. A faixa de freqüências utilizada cobriu de 0.001 Hz até 300 Hz, o que permitiu investigar de 100 m até 60 km de profundidade. Os dados apresentam-se afetados pelo efeito de distorção estática. Para corrigir este efeito foi utilizada a mediana da resistividade do primeiro condutor, correspondente à Formação Solimões. Foi utilizado o invariante do tensor MT para interpretar a estrutura geo-elétrica do Juruá. As seções geo-elétricas foram obtidas a partir do agrupamento dos dados resultantes da transformação de Bostick e da inversão 1D de Occam, para cada estação. Foi identificada uma seqüência de camadas condutivas e resistivas, correspondentes ao pacote sedimentar, uma zona de falhas e o topo do embasamento geo-elétrico, caracterizando a Bacia do Solimões. Abaixo do embasamento geo-elétrico foram também identificados uma zona condutora, seguida por uma camada de baixa condutividade, a profundidades iguais ou superiores a 20 km. Esta camada é interpretada como sendo de composição de gabro, estando associada a processos de acreção vertical, intimamente ligados à estabilização crustal e espessamento da litosfera. Os resultados apresentam uma boa concordância com os perfis de resistividade de poços e dados sísmicos de superfície.

Hospitalizations for Conditions Sensitive to Primary Care: A Geo-Epidemiological Profile Analysis of in a Hospital in the Sao Paulo State, From July 2010 to June 2011

The primary health care has been recognized as one of the key components of an effective health system. In its most developed form, the primary health care is the first contact with the health system and the site responsible for the organization of health care over time: individuals, their families and the general population; seeks to provide balance between the two goals of a national health system, which are improving the health of the population and provide equitable distribution of resources. Hospitalizations for primary care sensitive conditions (HPCSC) may be associated with deficiencies of service coverage primary health care or its effectiveness. Hospitalization rates can and should represent a warning sign, triggering mechanisms for analysis and search for explanations for these problems. The use of hospitalization data for HPCSC can serve as indicators of inequality in the health system, contributing to the evaluation of the deployment and implementation of health policies.

Methods and results of a search for gravitational waves associated with gamma-ray bursts using the GEO 600, LIGO, and Virgo detectors

In this paper we report on a search for short-duration gravitational wave bursts in the frequency range 64 Hz-1792 Hz associated with gamma-ray bursts (GRBs), using data from GEO 600 and one of the LIGO or Virgo detectors. We introduce the method of a linear search grid to analyze GRB events with large sky localization uncertainties, for example the localizations provided by the Fermi Gamma-ray Burst Monitor (GBM). Coherent searches for gravitational waves (GWs) can be computationally intensive when the GRB sky position is not well localized, due to the corrections required for the difference in arrival time between detectors. Using a linear search grid we are able to reduce the computational cost of the analysis by a factor of O(10) for GBM events. Furthermore, we demonstrate that our analysis pipeline can improve upon the sky localization of GRBs detected by the GBM, if a high-frequency GW signal is observed in coincidence. We use the method of the linear grid in a search for GWs associated with 129 GRBs observed satellite-based gamma-ray experiments between 2006 and 2011. The GRBs in our sample had not been previously analyzed for GW counterparts. A fraction of our GRB events are analyzed using data from GEO 600 while the detector was using squeezed-light states to improve its sensitivity; this is the first search for GWs using data from a squeezed-light interferometric observatory. We find no evidence for GW signals, either with any individual GRB in this sample or with the population as a whole. For each GRB we place lower bounds on the distance to the progenitor, under an assumption of a fixed GW emission energy of 10(-2)M circle dot c(2), with a median exclusion distance of 0.8 Mpc for emission at 500 Hz and 0.3 Mpc at 1 kHz. The reduced computational cost associated with a linear search grid will enable rapid searches for GWs associated with Fermi GBM events once the advanced LIGO and Virgo detectors begin operation.
