A Poética de Adélia Prado: espaço de articulação entre língua portuguesa e língua literária / The poetry of Adéilia Prado: articulation space between portuguese language and literary language

Maria Celeste de Castro Machado 31 March 2010 (has links)
A tese estuda a obra poética de Adélia Prado sob o ponto de vista da Estilística. Mostra que a metáfora é o recurso mais afeito a construir a língua literária e, no caso da poetisa, modelá-la em português. O estudo atesta que a linguagem conotativa da poetisa alcança os três níveis da língua e promove o inesperado e o distante da expressão comum. Afirma a importância da polifonia e da intertextualidade , além da excelência do discurso indireto livre na criação literária, não só da poetisa, mas de todo uso da língua portuguesa como ferramenta de expressão poética, principalmente se a intenção do autor é criar o discurso surrealista. A pesquisa mostra que há, na obra, um grande número de poemas em que predomina a linguagem religiosa católica. Ocorre a expressão da alma feminina , marcada com orgulho pela poetisa. A autora cria prosodemas, inaugura neologismos ,aproveitando todos os processos de criação vocabular. Assim, a obra se notabiliza pelo aproveitamento da sonoridade das palavras, pela escolha lexical inédita, por uma estrutura frasal apositiva, evocativa, sucinta e nominal, não escravizada às regras do registro culto como padrão literário. A tese reconhece que a autora lida eficientemente com as classes de palavras, com a construção nominal e com uma estruturação sintática peculiar, em que sobressai a oração adjetiva com função de sujeito, apesar de conter verbo: a oração adjetiva subjetivada. A essência da pesquisa são os conjuntos metafóricos, verdadeiros modelos universais, que permitem reconhecer a possível existência de uma língua literária em português. No mesmo contexto, focaliza um grupo de poemas chamados de telegráficos, curtos e de teor filosófico. Tal qualidade metafórica mostra a importância da poetisa Adélia Prado para a articulação da língua literária em língua portuguesa / The thesis studies the poetry of Adelia Prado in the view of the stylistics. It shows that the use of metaphor is more used to construct the literary language and in the case of the poet, model it in Portuguese. The study shows that the connotative language of the poet reaches the three levels of language and promotes the unexpected and far from the common expression. Emphasizes the importance of polyphony and intertextuality, and the excellence of free indirect discourse in literary creation not only of the poet, but all use the English language as a tool of poetic expression, especially if the author's intention is to create the surreal speech. Research shows that there is in the works, a large number of poems in the language that dominates religious Catholic. Is the expression of the feminine soul, marked with pride by poet. The author creates prosodemas inaugurates new words, taking advantage of all the processes of creation vocabulary. Thus, the work is distinguished by the use of the sound of words, the lexical choice unprecedented, for a test patch phrasing, evocative, succinct and nominal, not enslaved to the rules of registration as a cult literary standard. The thesis acknowledges that the author deals effectively with classes of words, with the building face and a syntactic structure peculiar in that it highlights the relative clause which functions as subject, although it contains verb: the relative clause subjectivized. The essence of the research is the sets metaphorically true "universal models" for recognizing the possible existence of a literary language in Portuguese. In the same context, focuses on a group of poems called "telegraph", short and philosophical content. This metaphorical quality shows the importance of the poet Adelia Prado for the articulation of the literary language in Portuguese

Com foco no trabalho, a pesquisa conduziu a análise ao entrelaçamento entre estratégias governamentais, regulação do mercado, organização do trabalho, políticas de gestão e relações de trabalho. Assim, trata-se de um trabalho que articula a análise das mudanças nas atividades de trabalho à reestruturação do setor. A pesquisa possui um recorte de natureza qualitativa, baseando-se em entrevistas com gestores, sindicalistas e trabalhadores, análise documental e observação direta de atividades de trabalho em unidades operacionais. O governo do presidente Fernando Henrique Cardoso propôs a reestruturação do setor postal brasileiro ao apresentar o projeto de "Lei Postal", que previa a liberalização e o fim gradual do monopólio dos Correios. O governo do Partido dos Trabalhadores rompeu com as propostas da "Lei Postal" e iniciou o processo de reestruturação organizacional da ECT, adequando-a ao arranjo institucional das sociedades anônimas e permitindo a constituição de subsidiárias, a internacionalização da atuação e a incorporação de novos segmentos de mercado. A organização do trabalho foi reestruturada no período a partir do Projeto de Gestão da Produtividade Aplicada aos Correios. A estratégia de reestruturação, baseada no compartilhamento de informações sobre métodos de gestão da produção, adotou estratégias de gestão desenvolvidas na área industrial para a gestão de atividades terciárias, configurando uma produção industrial de serviço. Com isso, investiu-se na automação da área de triagem, na modernização e terceirização da rede de atendimento e, sobretudo, na reformulação dos Centros de Distribuição Domiciliária. Nestas unidades operacionais, o processo de reestruturação resultou na configuração de relações de trabalho marcadas pela cadência acelerada das atividades e pela noção de tempo escasso para cumprir os prazos estipulados, aspectos que tornam as atividades de trabalho cada vez mais fragmentadas e individualizadas, já que centradas individualmente em cada funcionário por meio da adoção da lógica do trabalho por tarefa. Assim, a individualização das metas e responsabilidades torna o dissenso e o conflito integrantes das relações interpessoais no âmbito da unidade operacional, canalizando as insatisfações não contra as ações gerenciais, mas contra os colegas de trabalho, individualizando demandas por mudanças e dificultando a solidariedade entre trabalhadores em demandas coletivas. A política de gestão de pessoas na estatal é marcada pela tensão. A política salarial e de benefícios, juntamente com a relativa estabilidade no emprego, constituem instrumentos de retenção da força de trabalho. Ao mesmo tempo, a participação nos lucros e resultados a partir de 2003, a adoção de novo plano de cargos, carreiras e salários em 2008, as negociações coletivas e as polêmicas em torno da terceirização da força de trabalho e as recentes negociações coletivas têm conduzido a crescentes tensões e à judicialização das negociações trabalhistas. Verifica-se também que a força de trabalho é predominantemente masculina e reproduz desigualdades de oportunidades entre homens e mulheres. Com a ascensão do PT ao governo, constata-se crescente participação de ex-sindicalistas no quadro de gestores / Abstract: The goal of this thesis is to discuss the transformation of work in the Brazilian Post Office between 1994 and 2011. By focusing on work, this research guides the analysis towards the entanglement between government strategies, market regulation, and the organization of work, management policies and labor relations. This work, therefore, brings together the analysis of changes in work activities and the restructuring of the industry. The research includes an overview of qualitative research, based on interviews with managers, trade unionists and workers, document analysis and direct observations of work activities in operational units. The administration of President Fernando Henrique Cardoso proposed a restructuring of the Brazilian postal services when it presented the "Postal Law" project, which provided for the gradual liberalization and end of the monopoly held by Post Office. The government led by the Workers Party (PT) broke with the proposals of the "Postal Law" and started an organizational restructuring process of the ECT, adapting it to the institutional arrangement of corporations and allowing the establishment of subsidiaries, the internationalization of activities and the incorporation of new market segments. The organization of work was restructured in this period based on the Project for Productivity Management Applied to the Post Office. The restructuring strategy, which was based on the sharing of information on production management methods, adopted management strategies developed in the industrial area for the management of tertiary activities, turning the post office into an industrial producer of services. This meant investing in the automation of the sorting process, modernizing and outsourcing the customer service network and, most of all, reformulating the Home Distribution Centers. In these operating units, the restructuring process resulted in the establishment of labor relations marked by the accelerating pace of activities and a sense that there was little time to meet deadlines. Aspects that make the work activities increasingly fragmented and individualized, since they are focused on each individual employee by adopting the piecework logic. The individualization of goals and responsibilities make dissent and conflict an integral part of interpersonal relationships within the operational unit, funneling grievances not against managerial actions, but against coworkers, individualizing demands for change, and hindering solidarity between workers in collective bargaining. The people management policy in the state company is marked by tension. Wage and benefit policies, in addition to relative employment stability, are instruments to retain the workforce. At the same time, profit sharing schemes since 2003, the introduction of new jobs, wages and career plans in 2008, collective bargaining, and the controversies surrounding the outsourcing of the workforce have led to rising tensions and the judicialisation of labor negotiations. We also see that the workforce is predominantly male and that inequalities of opportunity between men and women are reproduced. With the rise of the PT to the government, there has been an increase in the participation of former unionists in management / Doutorado / Ciencias Sociais / Doutor em Ciências Sociais

O art déco na Obra Getuliana. Moderno antes do modernismo / Art Deco in the Obra Getuliana (Getulio Vargas Era). The modern before the modernism.

Reis, Márcio Vinicius 23 May 2014 (has links)
Trata-se de estudo investigativo de mão dupla acerca do art déco enquanto expressão primaz do moderno - não modernista - na Obra Getuliana, que assinalada pelos inúmeros edifícios públicos erigidos no período de 1930 a 1945, contribuiu para disseminá-lo no país. A princípio buscou-se explicitar em forma de panorama, uma parcela da vultosa produção arquitetônica oficial desse período, a cargo das seções de engenharia e arquitetura dos ministérios civis. Para tal, recorreu-se ao universo das exposições propagandísticas das realizações do governo estadonovista, ocorridas a partir de 1938 no antigo Distrito Federal, nas quais a Obra Getuliana esteve em evidência. A saber: Exposição do 30º aniversário do Ministério da Viação e Obras Públicas (1938); Exposição do Estado Novo (1938); Exposição do Ministério da Guerra (1941); e Exposição de Edifícios Públicos (1944). Como meio de se atestar o proposto, particularizou-se as produções do Ministério da Viação e Obras Públicas (MVOP) e Ministério da Educação e Saúde (MES), centradas respectivamente na arquitetura postal do Departamento de Correios e Telégrafos (DCT) e hospitalar relativa aos sanatórios para tuberculosos. Intentou-se também remontando o \"sistema de obras\" criado em 1939 para coordenar a referida produção oficial, e gerido pelo Departamento Administrativo do Serviço Público (DASP), entendê-la como alvo da política de racionalização dos serviços públicos pelo órgão máximo do executivo. Evidenciar as preocupações arquitetônicas oficiais relacionadas à estética e monumentalidade requeridas para os edifícios públicos nascidos dentro de um contexto político autoritário, mas progressista, foi outra forma de se averiguar a preponderância do art déco na Obra Getuliana. Nesse quesito, lançou-se mão da Revista do Serviço Público (1937-), veículo de comunicação entre Governo e funcionalismo, e de importantes registros da Obra e seu \"sistema\". / This is a two way investigative study about Art Deco whereas prime expression of the modern, but not modernist, in the Obra Getuliana, which was marked by numerous public buildings erected in the period from 1930 to 1945, thereby contributing to disseminate it in the country. At first we tried to explain it in shaped of panorama, a portion of the bulky official architectural production of this period, in charge of the sections of civil engineering and architecture departments. To this end, we adopted the universe of propagandistic exhibition of the achievements of the New State government occurred since 1938 in the former Federal District , in which the Obra Getuliana was in evidence . Namely : Exhibition of the 30th anniversary of the Ministry of Roads and Public Works (1938) ; Exposition of the New State (1938); Exhibition of the Ministry of War (1941) and Exhibition of Public Buildings (1944). As a means of proving the proposed, it was particularized the productions of the Ministry of Roads and Public Works (MVOP) and Ministry of Education and Health (MES), centered respectively on postal architecture of the Department of Posts and Telegraphs (DCT) and hospital on sanatoriums for tuberculosis. It was also attempted reassembling the \"system of works\" created in 1939 to coordinate such official production , and managed by the Administrative Department of Public Service (DASP),to understand it as a target for rationalization of public services policy by the highest body of the executive . Another way to determine the preponderance of art deco style in Obra Getuliana was to highlight the oficial architectural concerns related to aesthetics and monumentality required for those public buildings that were born within an authoritarian political context, but progressive. In this aspect, it made use of the Journal of Public Service (1937), vehicle of communication between government and civil service, and important records of the Obra and its \"system\".

A physics-based statistical random telegraph noise model / Um modelo estatistico e fisicamente baseado para o minimo RTN

Silva, Maurício Banaszeski da January 2016 (has links)
O Ruído de Baixa Frequência (LFN), tais como o ruído flicker e o Random Telegraph Noise (RTN), são limitadores de performance em muitos circuitos analógicos e digitais. Para transistores diminutos, a densidade espectral de potência do ruído pode variar muitas ordens de grandeza, impondo uma séria limitação na performance do circuito e também em sua confiabilidade. Nesta tese, nós propomos um novo modelo de RTN estatístico para descrever o ruído de baixa frequência em MOSFETs. Utilizando o modelo proposto, pode-se explicar e calcular o valor esperado e a variabilidade do ruído em função das polarizações, geometrias e dos parâmetros físicos do transistor. O modelo é validado através de inúmeros resultados experimentais para dispositivos com canais tipo n e p, e para diferentes tecnologias CMOS. É demonstrado que a estatística do ruído LFN dos dispositivos de canal tipo n e p podem ser descritos através do mesmo mecanismo. Através dos nossos resultados e do nosso modelo, nós mostramos que a densidade de armadilhas dos transistores de canal tipo p é fortemente dependente do nível de Fermi, enquanto para o transistor de tipo n a densidade de armadilhas pode ser considerada constante na energia. Também é mostrado e explicado, através do nosso modelo, o impacto do implante de halo nas estatísticas do ruído. Utilizando o modelo demonstra-se porque a variabilidade, denotado por σ[log(SId)], do RTN/LFN não segue uma dependência 1/√área; e fica demonstrado que o ruído, e sua variabilidade, encontrado em nossas medidas pode ser modelado utilizando parâmetros físicos. Além disso, o modelo proposto pode ser utilizado para calcular o percentil do ruído, o qual pode ser utilizado para prever ou alcançar certo rendimento do circuito. / Low Frequency Noise (LFN) and Random Telegraph Noise (RTN) are performance limiters in many analog and digital circuits. For small area devices, the noise power spectral density can easily vary by many orders of magnitude, imposing serious threat on circuit performance and possibly reliability. In this thesis, we propose a new RTN model to describe the statistics of the low frequency noise in MOSFETs. Using the proposed model, we can explain and calculate the Expected value and Variability of the noise as function of devices’ biases, geometry and physical parameters. The model is validated through numerous experimental results for n-channel and p-channel devices from different CMOS technology nodes. We show that the LFN statistics of n-channel and p-channel MOSFETs can be described by the same mechanism. From our results and model, we show that the trap density of the p-channel device is a strongly varying function of the Fermi level, whereas for the n-channel the trap density can be considered constant. We also show and explain, using the proposed model, the impact of the halo-implanted regions on the statistics of the noise. Using this model, we clarify why the variability, denoted by σ[log(SId)], of RTN/LFN doesn't follow a 1/√area dependence; and we demonstrate that the noise, and its variability, found in our measurements can be modeled using reasonable physical quantities. Moreover, the proposed model can be used to calculate the percentile quantity of the noise, which can be used to predict or to achieve certain circuit yield.

Volunteer Tourism : How the public opinion has changed and how Post-development ideas are shaping the discourse on volunteer tourism

Bäck, Sabina January 2018 (has links)
Volunteer tourism is a globally, popular and well-known field in which anyone may participate. During recent years the industry has increasingly received some criticism, in contrast to the otherwise quite commonly positive view of it. Hence, this thesis is taking a closer look at the industry and the discourse surrounding it and how the public opinion has changed during the last years. It will bring into light the impact volunteer tourism has both on the local communities and the volunteer tourists themselves. This will be done with respect to the following cases; positive, critical and seeing both sides of the discourse. The data derives from secondary and tertiary sources, the majority from articles from four of the world’s biggest newspapers. Post-Development theory will be used to identify the ideas regarding the discourse, which will be done with an approach of structured, focused comparison and critical discourse analysis. Additionally it will aim to identify the pros and cons with volunteer tourism and discuss why one of the perspectives might require more attention than it has had up until now. Significantly though, it will aim to provide the reader with an overall and objective view of the field.

Emerging Non-Volatile Memory Technologies for Computing and Security

Govindaraj, Rekha 31 May 2018 (has links)
With CMOS technology scaling reaching its limitations rigorous research of alternate and competent technologies is paramount to push the boundaries of computing. Spintronic and resistive memories have proven to be effective alternatives in terms of area, power and performance to CMOS because of their non-volatility, ability for logic computing and easy integration with CMOS. However, deeper investigations to understand their physical phenomenon and improve their properties such as writability, stability, reliability, endurance, uniformity with minimal device-device variations is necessary for deployment as memories in commercial applications. Application of these technologies beyond memory and logic are investigated in this thesis i.e. for security of integrated circuits and systems and special purpose memories. We proposed a spintonic based special purpose memory for search applications, present design analysis and techniques to improve the performance for larger word lengths upto 256 bits. Salient characteristics of RRAM is studied and exploited in the design of widely accepted hardware security primitives such as Physically Unclonable Function (PUF) and True Random Number Generators (TRNG). Vulnerability of these circuits to adversary attacks and countermeasures are proposed. Proposed PUF can be implemented within 1T-1R conventional memory architecture which offers area advantages compared to RRAM memory and cross bar array PUFs with huge number of challenge response pairs. Potential application of proposed strong arbiter PUF in the Internet of things is proposed and performance is evaluated theoretically with valid assumptions on the maturity of RRAM technology. Proposed TRNG effectively utilizes the random telegraph noise in RRAM current to generate random bit stream. TRNG is evaluated for sufficient randomness in the random bit stream generated. Vulnerability and countermeasures to adversary attacks are also studied. Finally, in thesis we investigated and extended the application of emerging non-volatile memory technologies for search and security in integrated circuits and systems.

Internationalization Of Communication In Greater Eastern Mediterranean Region Turkey, Greece And Israel

Ozyurt, Figen Gulcin 01 July 2007 (has links) (PDF)
This thesis analyzes the current and possible impacts of the new global information and communication order regime institutionalized by the 1993 WTO agreements, GATS and TRIPS, and the following 1997 BTS agreement on Turkey, Greece and Israel, telecommunications markets, three important countries of the GEMED region. Since the early 1980s these countries have showed significant efforts to establish telecommunications systems and computer networks based on high- technology. They have adopted corporate-oriented strategies and complemented necessary changes consisting up of four stages: liberalization, deregulation, corporatization and privatization in order to internationalize and to realize full liberalization of their national telecommunications markets. Full liberalization and resulting internationalization process has increased interests of global telecommunications giants seeking new markets for their IT products and services based on NGN technologies to enter into the Turkish Greek, and Israeli telecommunications markets. Huge costs of NGN technologies will inevitably accelerate merging and resulting concentration process in the hands of the very few numbers of conglomerates will likely conclude with &ldquo / back to natural monopoly position&rdquo / whose rules will be defined by private monopoly consisting up of merging two or three the most powerful private conglomerates.

Analyse des effets des déplacements atomiques induits par l’environnement radiatif spatial sur la conception des imageurs CMOS / Analysis of displacement damage effects on CMOS image sensor design

Virmontois, Cédric 23 March 2012 (has links)
L' imagerie spatiale est aujourd'hui un outil indispensable au développement durable, à la recherche et aux innovations scientifiques ainsi qu’à la sécurité et la défense. Fort de ses excellentes performances électro-optiques, de son fort taux d’intégration et de la faible puissance nécessaire à son fonctionnement, le capteur d’images CMOS apparait comme un candidat sérieux pour ce type d’application. Cependant, cette technologie d’imageur doit être capable de résister à l’environnement radiatif spatial hostile pouvant dégrader les performances des composants électroniques. Un nombre important d’études précédentes sont consacrées à l’impact des effets ionisants sur les imageurs CMOS, montrant leur robustesse et des voies de durcissement face à de telles radiations. Les conclusions de ces travaux soulignent l’importance d’étudier les effets non-ionisants, devenant prépondérant dans les imageurs utilisant les dernières évolutions de la technologie CMOS. Par conséquent, l’objectif de ces travaux de thèse est d’étudier l’impact des effets non-ionisants sur les imageurs CMOS. Ces effets, regroupés sous le nom de déplacements atomiques, sont étudiés sur un nombre important de capteurs d’images CMOS et de structures de test. Ces dispositifs sont conçus avec des procédés de fabrication CMOS différents et en utilisant des variations de règle de dessin afin d’investiguer des tendances de dégradation commune à la technologie d’imager CMOS. Dans ces travaux, une équivalence entre les irradiations aux protons et aux neutrons est mise en évidence grâce à des caractéristiques courant-tension et des mesures de spectroscopie transitoire de niveau profond. Ces résultats soulignent la pertinence des irradiations aux neutrons pour étudier les effets non-ionisants. L’augmentation et la déformation de l’histogramme de courant d’obscurité ainsi que le signal télégraphique aléatoire associé, qui devient le facteur limitant des futures applications d’imagerie spatiale, sont évalué et modélisés. Des paramètres génériques d’évaluation des effets des déplacements atomiques sont mis en évidence, permettant de prévoir le comportement des capteurs d’images CMOS en environnement radiatif spatial. Enfin, des méthodes d’atténuation et des voies de durcissement des imageurs CMOS limitant l’impact des déplacements atomiques sont proposées. / Today, space imaging is an essential tool for sustainable development, research and scientific innovation as well as security and defense. Thanks to their good electro-optic performances and low power consumption, CMOS image sensors are serious candidates to equip future space instruments. However, it is important to know and understand the behavior of this imager technology when it faces the space radiation environment which could damage devices performances. Many previous studies have been focused on ionizing effects in CMOS imagers, showing their hardness and several hardening-by-design techniques against such radiations. The conclusions of these works emphasized the need to study non-ionizing effects which have become a major issue in the last generation of CMOS image sensors. Therefore, this research work focuses on non-ionizing effects in CMOS image sensors. These effects, also called displacement damage, are investigated on a large number of CMOS imagers and test structures. These devices are designed using several CMOS processes and using design rule changes in order to observe possible common behaviors in CMOS technology. Similarities have been shown between proton and neutron irradiations using current-voltage characteristics and deep level transient spectroscopy. These results emphasize the relevance of neutron irradiations for an accurate study of the non-ionizing effects. Then, displacement damage induced dark current increase as well as the associated random telegraph signal are measured and modeled. Common evaluation parameters to investigate displacement damage are found, allowing imager behavior prediction in space radiation environment. Finally, specific methods and hardening-by-design techniques to mitigate displacement damage are proposed.
