O Processo de trabalho e a organização operária na Azaléia Nordeste à época da mundialização do capital

Santos, Márcio Soares 17 August 2008 (has links)
This paper has as objective to analyze the work process and the syndical worker’s organization from the footwear industry Azaléia Nordeste. The industrial unit of the Azaléia Nordeste is hosted in the bahian city of Itapetinga since 1997, and belongs to the Grupo Calçados Azaléia S/A, the latter, since 1958, with headquarters in the city of Parobé, in the Brazilian state of Rio Grande do Sul. Knowing that it’s not possible to understand in a satisfactory way the coming of the Azaléia industry to Bahia, and in particular to the city of Itapetinga and surrounding region, it became necessary to search the most general determination that had produced the favorable conditions to the current productive displacements. Thus, the research deals with subjects such as the structural crisis of the capital since the 70s, the worldwide of the capital, the flexible accumulation and the most recent productive reorganization of the capital, all remarkable events between the end of the years 1970 and beginning of the 1980 decade, but which have lasted until the current days. There are also some issues which are dealt as the State crisis, the decline of the Fordism, fight of classes, the lack of work conditions and the unionism crisis. Beyond the macrostructure determination, particularities had also been verified as being associated to these phenomena, as much in national level (Brazil), as state (Bahia) and even municipal (Itapetinga). Thus, the introducing of the Azaléia in the micron-region of Itapetinga must be explained by the joint of the structural changes of the capitalism with the factors and specific situations, of national regional and local character; or either, the arrival of the Azalea to the micron-region of Itapetinga, with all its consequences, could only be fully understood from the dialectic joint of the general with the particular one. This joint is one of the nexuses of the perspective of the totality. And the most fruitful formularization of the totality notion used the legacy of Marx and Engels, later developed by the Marxism. It’s about the historical dialectic materialism. For this reason, one searched to apply in this study this theoretical referential. / Fundação de Amparo a Pesquisa do Estado de Alagoas / Esta dissertação tem por objeto analisar o processo de trabalho e a organização sindical dos trabalhadores da indústria de calçados Azaléia Nordeste. A unidade industrial da Azaléia Nordeste está sediada no município baiano de Itapetinga desde 1997, e pertence ao Grupo Calçados Azaléia S/A, este, desde 1958, com sede no município de Parobé, no estado brasileiro do Rio Grande do Sul. Sabendo não ser possível compreender de maneira satisfatória a vinda da Azaléia para a Bahia, e em particular para o município de Itapetinga e região circunvizinha, fez-se necessário buscar as determinações mais gerais que engendraram as condições favoráveis aos atuais deslocamentos produtivos. Assim, a pesquisa aborda temas como a crise estrutural do capital desde os anos 1970, a mundialização do capital, a acumulação flexível e a mais recente reestruturação produtiva do capital, todos acontecimentos marcantes entre o final dos anos 1970 e início da década de 1980, mas que perduram até os dias atuais. São abordadas também questões como a crise do Estado, o declínio do fordismo, luta de classe, a precarização das condições de trabalho e a crise do sindicalismo. Para além das determinações macro-estruturais, também foram verificadas particularidades associadas a estes fenômenos, tanto em nível nacional (Brasil), quanto estadual (Bahia) e mesmo municipal (Itapetinga). Assim, a implantação da Azaléia na micro-região de Itapetinga deve ser explicada pela articulação das mudanças estruturais do capitalismo com os fatores e situações específicas, de caráter nacional, regional e local; ou seja, a chegada da Azaléia à micro-região de Itapetinga, com todas as suas conseqüências, somente poderá ser plenamente compreendida a partir da articulação dialética do geral com o particular. Esta articulação é um dos nexos da perspectiva da totalidade. E a mais fecunda formulação da noção de totalidade vale-se do legado de Marx e Engels, posteriormente desenvolvido pelo marxismo. Trata-se do materialismo histórico-dialético. Por esse motivo, buscou-se aplicar nesse estudo esse referencial teórico.

Estratégias de diferimento na produção primária e secundária da pastagem natural / Deferrals strategies in primary and secondary production of natural grassland

Costa, João Luiz Benavides January 2015 (has links)
As pastagens naturais são a base alimentar para grande parte da pecuária de corte no Rio Grande do Sul, ainda que este ambiente seja susceptível a variações climáticas estacionais que afetam o crescimento da vegetação, quais sejam as baixas temperaturas de inverno e deficiência hídrica no verão. A fim de minimizar os efeitos deletérios proporcionados à vegetação por períodos climáticos desfavoráveis, a presente dissertação tem por objetivo avaliar o efeito de duas estratégias de diferimento na produção animal e vegetal de uma pastagem natural da região fisiográfica da Campanha. O trabalho foi desenvolvido na Embrapa Pecuária Sul, localizada no município Bagé, onde foram avaliados duas épocas de diferimento: primavera (DP) e verão-outono (DVO) e um tratamento testemunha sem diferimento (SD), durante dois anos. O delineamento foi inteiramente casualizado, com medidas repetidas no tempo (ano) e três repetições de área por tratamento. Foram utilizados novilhos da raça Braford em lotação continua com carga variável de forma a manter uma oferta média de forragem de 10 kg MS/100 kg de peso corporal/dia. A taxa média de acúmulo de pasto e a produção liquida de forragem foi semelhante entre tratamentos, com médias de 14,7 kg MS/ha/dia e 4648 kg MS/ha/ano, respectivamente. Já a massa média de forragem foi 27% superior nos tratamentos com diferimento. Com relação à produção animal, o primeiro ano permitiu taxa de lotação média 14% superior ao segundo ano e, na média dos anos o diferimento de primavera foi 21% superior aos demais. O ganho médio diário e a produção animal por área apresentou interação entre ano de avaliação e tratamento, sendo observado maiores GMD no primeiro e segundo ano para SD e DVO, com média de 0,321 e 0,340 kg, respectivamente. De uma forma geral o que explica essa interação é a diferença no número de dias que os animais permaneceram pastoreando cada tratamento e a estrutura da pastagem pós período de diferimento. As estratégias de diferimento não apresentaram superioridade na produção de pasto frente ao tratamento testemunha devido a ocorrência de condições climáticas anormalmente favoráveis nos anos avaliados. Ainda assim, o diferimento de primavera no primeiro ano e de verão-outono no segundo ano, apresentaram desempenho semelhante ao tratamento sem diferimento, mesmo estes apresentando um período de pastoreio consideravelmente menor. / The natural pastures are the main food resource for most portion of the beef cattle in Rio Grande do Sul, even though, this environment to be susceptible to seasonal climatic variations that affect vegetation growth, namely the low winter temperatures and water stress in summer. In order to minimize the deleterious effects provided for vegetation by unfavorable climatic periods, this thesis aims to evaluate the effect of two deferral strategies in animal and plant production of natural pasture in the Campanha physiographic region. The study was conducted in Embrapa South Livestock located natural in the municipality Bagé, where were evaluated two deferral periods: spring and summer-autumn, and a control treatment without deferral, during two years of treatment application. The design was completely randomized with repeated measurements over time (year) and three replications per treatment. Braford steers were used in continuous stocking with variable load in order to maintain an average forage allowance of 10 kg DM/100 kg Life Weight per day. The accumulation forage average rate and the net forage production was similar between treatments, with averages of 14.7 kg DM/ha/day and 4648 kg DM/ha/year, respectively. The average forage mass was 27% higher in treatments with deferral. Regarding to animal production, the first year had an average stocking rate 14% higher than the second year and the average of the years the spring deferral was 21% superior to the others. The average daily gain and animal production by area showed interaction between year of assessment and treatment, being observed greater average daily gain in the first and second year for without deferral and summer-autumn deferral, averaging 0.321 and 0.340 kg, respectively. In general way which explains that interaction is the difference in the number of days that animals were grazing each treatment and the structure of pasture at post deferral period. The deferral strategies did not show superiority in the production of pasture in front of the control treatment due to non-occurrence of normal adverse weather conditions in the evaluated years. Still, the spring deferral in the first year and the summerautumn deferral in the second year showed similar performance to treatment without deferral, even these having considerably less grazing period.

Studium inhibice ABC lékových efluxních transportérů vybranými inhibitory tyrozinkináz pomocí akumulačních metod s cytostatickými substráty / Study of ABC drug efflux transporter inhibition by selected tyrosine kinase inhibitors using accumulation methods with cytostatic substrates

Suchá, Simona January 2018 (has links)
Charles University Faculty of Pharmacy in Hradec Králové Department of Pharmacology & Toxicology Student: Simona Suchá Supervisor: RNDr. Jakub Hofman, Ph.D. Title of diploma thesis: Study of ABC drug efflux transporter inhibition by selected tyrosine kinase inhibitors using accumulation methods with cytostatic substrates ATP-binding cassette (ABC) drug efflux transporters are transmembrane proteins that utilize the energy from ATP hydrolysis to drive transport of endogenous and exogenous compounds out of the cell. The overexpression of ABC transporters plays a crucial role in the development of multidrug resistance (MDR), a phenomenon responsible for the failure of chemotherapy. Tyrosine kinase inhibitors (TKI) represent novel beneficial therapeutic approach in cancer treatment. TKI block tyrosine kinases which regulate important cellular processes. Deregulation of these enzymes can lead to various types of cancers. In the present work, we investigated interaction potential of selected TKI (alectinib, brivanib, osimertinib, selumetinib) in MDCKII parent cell line and those transduced with human efflux transporters ABCB1, ABCC1 and ABCG2. Using the accumulation studies, we determined the amount of accumulated model substrates (daunorubicin, mitoxantrone) and evaluated the inhibitory effect of...

Effects of off-axis melt supply at fast-spreading mid-ocean ridges: A study of the 9-10n region of the East Pacific Rise

Durant, Douglas Troy, 1965- 06 1900 (has links)
xiv, 103 p. : ill. (some col.) / Results from a recent mid-ocean ridge tomography study along the fast-spreading, northern East Pacific Rise (EPR) reveal that the axis of mantle upwelling beneath the ridge is skewed with respect to the spreading axis, giving rise to regions of both rise-centered and off-axis mantle melt accumulation. Here, we investigate the effects of off-axis melt accumulation on the architecture of overlying crust as well as off-axis melt delivery on crustal construction along the ridge axis. We first present evidence for off-axis magmatism 20 km from the spreading center in 300-ka-old crust overlying a region of off-axis melt supply. Seismic data reveal an intrusive complex ∼2 km beneath the seafloor that is limited in lateral extent (<5 km) and comprises a melt lens underlain by low-velocity, high-attenuation crust, which provides the necessary conditions to drive off-axis volcanic and hydrothermal activity. We next present results from thermodynamic modeling that show systematic, along-axis variations in the depth of crystallization and degree of differentiation of magma produce crustal density variations of ∼0.1 g/cm 3 . These density anomalies are on the order inferred from a recent study that shows increasing axial depth along the northern EPR correlates with an increase in crustal density and offset of mantle upwelling with respect to the ridge axis. Our results, along with geophysical and geochemical data from the 9°-10°N region of the EPR, suggest that along-axis deeps correspond with magmatic systems that have significant near-Moho (i.e., crust-mantle transition) crystallization, which we attribute to off-axis delivery of mantle melt. As this investigation is motivated by the EPR tomography results, we conclude with a numerical study that examines the travel time sensitivity of Pn , a sub-crustal head wave commonly used in local travel time tomography, to crustal and mantle heterogeneity. Our results indicate that Pn travel times and Fresnel zones are insensitive to normal sub-axial crustal thickness anomalies, mantle velocity gradients and crust-mantle velocity contrast variations and that mantle low-velocity zones must be at least 3 km thick to produce significant, near-constant Pn delay times. Our data support the validity and interpretation of the EPR tomography results. This dissertation includes both previously published and unpublished co-authored material. / Committee in charge: Dr. Douglas R. Toomey, Chairperson; Dr. Paul J.

Phytoextraction of chromium and iron from contaminated soil using psoralea pinnata

Ochonogor, Oluchuku Richie 27 May 2014 (has links)
The overall efficiency of plants to remediate soils contaminated by metals depends on their growth ability especially on soils with low-fertility. For twelve weeks, the ability of Psoralea pinnata to grow well and remove chromium and iron from artificially contaminated soil was tested. The concentrations of chromium and iron in two soils obtained from different sources namely, University of South Africa premises (US) and commercial potting soil (PS) were 80 ppm, 130ppm, 180ppm, 230ppm, 280ppm, 330ppm, 380pp, 430ppm and 480ppm. Psoralea pinnata was transplanted into the contaminated soils and the experiments were watered daily to maintain 70% moisture at field capacity in a greenhouse. Shoot height and root length of Psoralea pinnata before and after planting were measured. Other parameters that were measured were number of leaves, wet shoot and dry weights, and wet root and dry weights. The growth of Psoralea pinnata, after 12 weeks of experimentation was noticeably affected by the concentrations of chromium and iron in the soil. The percentage increases in shoot height of Psoralea pinnata in the PS Soil (C-PS, 48cm from initial shoot height of 12.6cm) treatments were generally higher than the increases in the US Soil (C-US, 45.2cm from initial shoot height of 12.8cm) treatments. Psoralea pinnata in the (US) treatments accumulated Fe (50.02 ppm) from the soil more than Cr (32.38ppm). In the (PS) treatments, Psoralea pinnata also accumulated more Fe (60.57 ppm) than Cr (38.34 ppm). In the experiments containing both Fe and Cr, the US treatments with 40 ppm each of Cr and Fe, chromium was initially mostly accumulated by Psoralea pinnata (68%). At higher concentrations (320 ppm) of the combined metals (Cr and Fe) treatment, more Fe (55%) was accumulated in Psoralea pinnata. This study however showed that Psoralea pinnata may not be an efficient phytoextraction plant for hyperaccumulation. / Environmental Sciences / M. Sc. (Environmental Management)

A lei geral da acumulação capitalista e a situação da classe trabalhadora nos Estados Unidos da América

Machado, Fernanda Valada January 2016 (has links)
Nesta dissertação, interpreta-se as causas e as consequências do processo de concentração da renda e da riqueza nos Estados Unidos da América a partir da teoria de Karl Marx. Defende-se, que a “Lei Geral da Acumulação Capitalista”, onde culmina a construção teórica de Marx do livro primeiro d’O Capital, é consistente para explicar a evolução histórica da situação da classe trabalhadora sob as relações sociais de produção capitalistas. Para isso, desenvolve-se a análise teórica essencialmente sobre as obras de Marx - d’O Capital e dos Grundrisse-, e o país que melhor exemplifica a análise teórica de Marx, é os Estados Unidos da América - a maior nação capitalista do mundo. Para tanto, são apresentados dados acerca da concentração da renda e da riqueza, da evolução das taxas de pobreza, discorre-se sobre o movimento trabalhista, sobre a legislação trabalhista e sobre os sindicatos. Apresenta-se o panorama histórico dos Estados Unidos, entre a construção do New Deal e a restauração conservadora sobre o invólucro “neoliberal”. / In this dissertation, interprets the causes and consequences of the process of concentration of income and wealth in the United States with Karl Marx's theory. It is argued that the "General Law of Capitalist Accumulation", which culminates the theoretical construction of Marx's first book of Capital, is consistent to explain the historical developments of the working class in the social relations of capitalist production. It develops the theoretical analysis primarily on the works of Marx - of Capital and Grundrisses-, and the country that best exemplifies the theoretical analysis of Marx is the United States - the largest capitalist nation in the world. For this purpose, data are presented about the concentration of income and wealth, changes in poverty rates, it talks about the labor movement on the labor legislation and on trade unions. It presents the historical background of the United States, including the construction of the New Deal and the conservative’s restoration under the "neoliberal"’s casing.

Dimensões do princípio do ne bis in idem / Perspectives of ne bis in idem principle

Keity Mara Ferreira de Souza e Saboya 31 October 2012 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Objetiva-se reconstruir o sentido e o alcance do princípio do ne bis in idem, estudando-se as interferências recíprocas do direito penal e do direito administrativo sancionador, com ênfase na concorrência normativa entre tais manifestações do ius puniendi do Estado, seus desdobramentos e os riscos que representam para a liberdade humana, especificamente em face da interdição de duplicidade ou multiplicidade punitiva encartada no princípio em comento. Estrutura-se o texto em três pilares: a primeira parte cuida dos aspectos mais universais do princípio do ne bis in idem, percorrendo tanto seu traçado histórico como seu reconhecimento internacional; a segunda parte examina a consistente experiência jurídica europeia, analisando os marcos teóricos e práticos relacionados à matéria; finalmente, a terceira parte atinge o âmago da investigação, enfocando teoricamente o princípio do ne bis in idem, de modo a renovar sua interpretação no plano nacional, redimensionando as convergências entre o direito penal e o direito administrativo sancionador, a unicidade da (re)ação repressiva do Estado e as possibilidades de enfrentamento das disfunções desse princípio no direito brasileiro. Demonstra-se que a acumulação de sanções de caráter punitivo, de natureza penal e/ou administrativa sancionadora, quando presentes os pressupostos de identidade de sujeito, de fatos e de fundamentos, é vedada pelo espectro de proteção do princípio do ne bis in idem. Postula-se, ainda, esclarecer se, nas situações de exacerbação punitiva com fins semelhantes ou confluentes, deverá sempre prevalecer a aplicação da lei penal. Espera-se, ademais, formular propostas para a regulamentação de conflitos nos casos de concorrência normativa entre o direito penal e o direito administrativo sancionador. Evidencia-se, enfim, que o objetivo principal da investigação é a plena compreensão do princípio do ne bis in idem, refletindo-se a respeito da ilegitimidade da acumulação de sanções penais e sanções administrativas, tão somente pelo fundamento de que não é possível a desvinculação das regras de independência entre a competência jurisdicional e a atribuição sancionadora da administração ou em razão de supostas indiferenças ontológicas entre os ilícitos penal e administrativo. / The purpose of this work is to reconstruct the meaning and scope of the principle of ne bis in idem, with the study of reciprocal interference of criminal law and sanctioning of administrative law, with an emphasis on competition rules between these manifestations of the penalizing authority of the State, its consequences and the risks posed to human freedom, especially in the face of prohibition of double or multiple punitive inset in principle under discussion.The text is structured on three pillars: the first part takes care of the most universal principle of ne bis in idem, covering both your track record as its international recognition; the second part examines the consistent European legal experience, analyzing the theoretical frameworks and related to practical matters; finally, the third part goes to the heart of research, focusing theoretically the principle of ne bis in idem in order to renew their interpretation at the national level, resizing the convergence between the criminal law and administrative law sanctioning the uniqueness the (re)action repressive state and the possibilities of coping with dysfunction of this principle in Brazilian law. It shows that the accumulation of punitive sanctions, criminal and/or administrative sanctions, if present assumptions identity of subject, facts and fundamentals, is forbidden by the specter of protection of the principle of ne bis in idem. It also intends to clarify whether, in cases of exacerbation punitive or confluent with similar purposes, shall always prevail criminal law enforcement. It is expected, moreover, to formulate proposals for the regulation of conflicts in cases of competition rules between the criminal law and administrative law sanctioning. It shows, finally, that the main objective of the investigation is fully understanding the principle of ne bis in idem, reflecting about the ilegitimacy accumulation of criminal penalties and administrative sanctions, especially with the fundament that it is not possible untying the rules of independence between the jurisdiction and the award of punitive or administration due to ontological indifferences between the illicit criminal and administrative.

Aveia branca (Avena sativa l.) como suplemento na terminação de novilhas em pastagem de aveia (Avena strigosa Schreb.) e azevém (Lolium multiflorum) / White oat (Avena sativa l.) supplementation to finishing heifers on pasture of oat (Avena strigosa Schreb.) and ryegrass (Lolium multiflorum)

Azevedo Junior, Ricardo Lima de 31 March 2015 (has links)
Conselho Nacional de Desenvolvimento Científico e Tecnológico / This study aimed to investigate the effect of supplementation with white oats grain on the performance of heifers of 21 and 33 months of age on temperate pastures and the influence on productive parameters of pasture, performance, carcass and meat characteristis. Twenty-four Charolais x Nellore heifers, 12 with an average age of 21 months and average weight of 194.9 kg; and 12 with an average age of 33 months and average weight of 270.3 kg, were assigned to the treatments: With supplementation (WITH): heifers kept on pasture of oat + ryegrass receiving broken white oat grain at 0.6% body weight; Without supplementation (WITHOUT): heifers exclusively on pasture of oat + ryegrass. The experiment had a completely randomized design, in a 2 x 2 factorial arrangement (two treatments x two ages); data were analyzed using the SAS statistical package (2013). The chemical analysis of qualitative simulation of grazing and white oat grain showed no differences (P≥0.05), for supplementation and age of heifers. The forage mass was significantly different (P≤0.05) with mean values of 966.16 and 774.76 kg/ha for heifers WITH and WITHOUT supplementation, respectively. The supplementation promoted a greater production of pasture (7116.03 vs. 6251.14 Kg /DM/ha) (P≤0.05). The stocking rate was significantly different (P≤0.05) for animals of different ages, 785.51 and 577.53 kg body weight/ha for heifers of 21 and 33 months of age, respectively. The daily body weight gain was statistically different (P≤0.05), with mean values of 1.40 and 1.20 kg body weight for heifers WITH and WITHOUT supplementation, respectively. The slaughter weight was influenced by age; heifers of 36 months of age were heavier than heifers of 24 months of age (422.71 vs. 336.83 kg) (P≤0,05). Hot and cold carcass yields were not influenced by supplementation and age of heifers. Supplementation significantly affected the absolute weight of carcass fat (47.75 vs. 41.60) (P≤0,05). Heifers of 24 months of age, without supplementation, presented a lower fat thickness (1.72 mm), thus determining a greater carcass cooling loss (2.38 kg/100 kg carcass) (P≤0,05). There were interactions for the variables palatability, juiciness and tenderness of the meat. / Objetivou-se neste estudo investigar a resposta da utilização da suplementação com o grão de aveia branca, no desempenho de novilhas de 21 e 33 meses de idade em pastagens de clima temperado e a resposta nos parâmetros produtivos da pastagem, no desempenho, características da carcaça e da carne. Foram utilizadas 24 novilhas cruzas Charolês x Nelore, sendo 12 com idade média inicial de 21 meses e peso vivo médio de 194,9 kg; e 12 com idade média inicial de 33 meses e peso vivo médio de 270,3 kg, distribuídas nos tratamentos: Com suplementação (COM): novilhas mantidas em pastagem de aveia + azevém, recebendo grão de aveia branca quebrada em nível de 0,6 % do peso vivo; Sem suplementação (SEM): novilhas mantidas exclusivamente em pastagem de aveia + azevém. O delineamento experimental foi o inteiramente casualizado, em fatorial 2 x 2 (dois tratamentos x duas idades), os dados foram analisados com o auxílio do pacote estatístico SAS (2013). Para as análises bromatológicas de simulação de pastejo e do grão de aveia branca não foram encontradas diferenças (P≥0,05), para a suplementação e idade das novilhas. A massa de forragem apresentou diferença (P≤0,05) com médias de 966,16 e 774,76 kg/ha para novilhas COM e SEM suplementação, respectivamente. A suplementação promoveu maior produção de pastagem (7116,03 vs. 6251,14 kg/MS/ha) (P≤0,05). A taxa de lotação apresentou diferença (P≤0,05) em relação à idade das novilhas, apresentando médias de 785,51 e 577,53 kg de peso vivo/ha para as novilhas de 21 e 33 meses, respectivamente. O ganho de peso vivo diário apresentou diferença (P≤0,05), apresentando médias de 1,40 e 1,20 kg de peso vivo para novilhas COM e SEM suplementação, respectivamente. O peso de abate foi influenciado pela idade, sendo as novilhas de 36 meses mais pesadas do que as novilhas de 24 meses de idade (422,71 vs. 336,83 kg) (P≤0,05). Os rendimentos de carcaça quente e fria não foram influenciadas pela suplementação e idade das novilhas. A suplementação influenciou o peso absoluto da gordura na carcaça (47,75 vs. 41,60) (P≤0,05). As novilhas de 24 meses e sem suplementação apresentaram menores valores de espessura de gordura (1,72 mm) (P≤0,05), determinando maior quebra ao resfriamento da carcaça (2,38 kg/100 kg de carcaça) (P≤0,05). Foram encontradas interações para as variáveis palatabilidade, suculência e maciez da carne.
