No. of bitstreams: 1 Rogério Murback Caielli.pdf: 1880774 bytes, checksum: 4f8f30139f635f486eb60fd9d904f198 (MD5) Previous issue date: 2017-12-07 / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / Interested in the relations between cities, the citizen and the arts, this project turns to the work of the French multi-media urban artist JR. The research is guided by the hypothesis that his production can be inserted in the so-called rebel culture, emphasizing the utopian content in its production, having the assumption to use art as an instrument of intervention and social revolution. The corpus of the research comprises the projects of JR that, since 2005, began to have international scope, such as Women are Heroes (2008 - 2010), Rio de Janeiro and Wrinkles of the City (2008-), Cuba . The artist transits among photography, video, dance, scenography, music and, in the limit, digital media, having a personal website as the final support of his interventions. Thus, in consonance with the extremely hybrid nature of the object and the research hypothesis, the communicational ambience and the intersemiotic relations among the mediatic discourses, involved in creative processes, are equally considered. The state of the art involves studies focused on the historical vanguards, such as Le Siècle Rebelle - Dictionaire de la Contestation au XX Siècle de Emmanuel de Waresquiel. The main theoretical references refer to the theories of the image, as formulated by Rancière in O Destino das Imagens and, alternatively, the Hubermasian theory, with emphasis on the reading model proposed in Diante da Imagem. Methodologically, the research is bibliographical and documentary. We believe that its relevance lies in unveiling an internationally renowned artist, still unkown among us and – above all - pointing out an interesting form of convergence between art and social communication / Interessado nas relações entre as cidades, o cidadão e as artes, este projeto volta-se para a obra do artista urbano multimidiático francês JR. A pesquisa é guiada pela hipótese de que sua produção pode ser inserida nas assim chamadas culturas rebeldes, ressaltando o teor utópico em sua produção; e ainda tem como pressuposto, utilizar a arte como um instrumento de intervenção e revolução social. O corpus da pesquisa compreende os projetos de JR que, a partir de 2005, passaram a ter abrangência internacional, incluindo ações como Women are Heroes (2008 - 2010),no Rio de Janeiro e Wrinkles of the City (2008- ),em Cuba. O artista transita entre a fotografia, o vídeo, a dança, a cenografia, a música e, no limite, o digital, tendo um site pessoal como suporte final de suas intervenções. Assim, a pesquisa se coloca em consonância com a natureza extremamente híbrida do objeto e do artista, a sua ambiência comunicacional e as relações intersemióticas entre os discursos midiáticos envolvidos nos referidos processos criativos. O estado da arte envolve estudos abalizados em torno das vanguardas históricas, a saber de Le Siècle Rebelle - Dictionaire de La Contestation au XX Siècle de Emmanuel de Waresquiel. Os principais referenciais teóricos são referentes às teorias da imagem, tal como formulada por Rancière em O Destino das imagens e, subsidiariamente, a teoria hubermasiana, com ênfase no modelo de leitura das proposto em Diante da Imagem. Metodologicamente, a pesquisa é bibliográfica e documental. Acreditamos que sua relevância está em desvendar um artista em trânsito dentro do universo da arte e de renome internacional, além de assinalar uma interessante forma de convergência entre a arte e a comunicação

Globale Finanzmärkte / Global financial markets

January 2005 (has links)
Sicherlich geht es bei der Gestaltung der gewaltigen globalen Finanzströme nicht darum, ein zweites Bretton Woods-System als Prokrustesbett herzurichten, sondern diese polymorphen Strukturen gilt es grenzüberschreitend zu regulieren. Das betonen Norbert Walter, Bernhard Speyer und Alexander Börsch in ihren Beiträgen. Oliver Keßler fragt, inwieweit der Wissensvorsprung von Finanzakteuren staatliche Regulierungsbemühungen unterwandert. Und Daniel Mügge stellt fest: Bei allen technischen Fragen der Regulierung gilt: Politique d´abord, es ist vorrangig ein politisches Problem! Im Kontext der Terrorismusbekämpfung sind illegale Finanzaktivitäten stärker ins Visier geraten. Diese Schnittstelle von Ökonomie und Sicherheit diskutieren Jan Bittner und Markus Lederer, wobei sie die Defizite bisheriger Strategien aufzeigen und den „genuin politischen Umgang“ mit den Finanzquellen des Terrorismus einfordern.

A partir da compreensão do direito como ideologia nas determinações inerentes à moderna sociedade civil-burguesa, trata-se de levantar a função específica do direito na particularidade histórica do capitalismo nacional. Na linha argumentativa apresentada observa-se que o direito no Brasil cumpriu função bem específica, com profundos engendramentos na lenta transição da colônia para a sociabilidade propriamente capitalista. O objetivo central deste trabalho é contribuir para a explicação do reflexo jurídico e de como este aparece no pensamento de Prado Jr. A hipótese central é de que o autor na maior parte de suas obras oscila entre uma visão economicista - deixando o direito secundarizado em relação à economia e à política - e a função ativa do direito. Esta última, inegavelmente presente em suas obras, entretanto, salta os olhos de forma implícita e não expressa. Por outro lado, quando se trata especificamente da questão agrária, Caio Prado Jr. se detêm profundamente nos engendramentos do problema analisado e a obscuridade da função do direito fica mais transparecida, pois sua análise ganha concretude. / This dissertation presents the results of the research on the appearance of the juridical phenomenon in the main historiographical works of Caio Prado Jr., in view of the formation of Brazilian via colonial capitalism. From the understanding of law as ideology in the determinations inherent to modern civil-bourgeois society, it is a question of raising the specific function of law in the historical particularity of national capitalism. In the argumentative line presented it is observed that the law in Brazil fulfilled a very specific function, with deep engenderings in the slow transition from colony to the sociability properly capitalist. The central objective of this work is to contribute to the explanation of the legal reflex and of how it appears in the thought of Prado Jr. The central hypothesis is that the author in most of his works oscillates between an economistic view - leaving the secondary right in relation the economy and politics - and the active function of law. This, undeniably present in his works, however, implicitly and not expressed. On the other hand, when it comes specifically to the agrarian question, Caio Prado Jr. dwells deeply on the engendraments of the problem analyzed and the obscurity of the function of law becomes more transparent, since its analysis gains concreteness.

A frase e sua teoria no horizonte de retrospecção de Mattoso Câmara / The sentence and its theory in the Mattoso Camara retrospection horizon

Silva, Francivaldo Lourenço da 18 June 2019 (has links)
Este trabalho apresenta o percurso histórico da ideia de frase a partir de sua presença na obra do linguista brasileiro Joaquim Mattoso Câmara Jr. (1904-1970). Entende-se por ideia de frase as representações que pretendem dar conta dos segmentos da cadeia dialógico-discursiva no âmbito das ciências ou disciplinas dedicadas ao estudo qualificado e especulativo da linguagem. Partiu-se do problema geral da definição da frase e de seu papel no estudo da linguagem. Mattoso Câmara, como linguista brasileiro, ilustra, por meio de suas reflexões sobre a questão da frase e de seu horizonte de retrospecção, os movimentos e transformações do percurso histórico do problema considerado; contribuiu, também, com os capítulos XI e XII de seu Princípios de linguística geral (1ª ed., 1941) para o esforço de precisão conceitual-terminológica da ideia de frase; o fez a partir da compreensão do caráter heteróclito da frase e de seu enquadramento teórico a partir da dicotomia saussuriana langue / parole. Este trabalho resulta do levantamento, a partir das pistas encontradas na obra de Mattoso Câmara, das emergências da ideia de frase e dos contextos epistemológicos em que surgem. O percurso de sua presença e de sua problematização no longo tempo do pensamento linguístico ocidental nos eixos espaço-temporais da Antiguidade Grega, da França racionalista e do Brasil que se moderniza permite compreender e localizar na história das ideias linguísticas brasileiras a contribuição de Mattoso Câmara à conceituação do termo frase. O viés teórico-metodológico deste trabalho é o da História das Ideias Linguísticas, na proposta do filósofo e historiador Sylvain Auroux. O cerne desta proposta teórico-metodológica é o saber metalinguístico constituído e/ou em vias de se constituir que pode ser de quatro tipos: especulativo, prático, técnico e competente (AUROUX, 1988). O conceito de ideia de frase subjacente a este trabalho resulta do saber metalinguístico de natureza especulativa, visto que é no âmbito do estudo qualificado que as representações que pretendem lidar com as entidades manifestadas no mundo sensível e identificadas pelos termos frase, sentença, oração, proposição, período e enunciado foram buscadas. / This work presents the historical course of sentence idea. The presence of discussions about sentence in the work of the Brazilian linguist Joaquim Mattoso Câmara Jr. (1904-1970) is the motive for elaboration of this historical course. Sentence idea is understood, in this work, by representations of dialogical-discursive chain segments in scope of sciences or disciplines dedicated to speculative study of language. It started from the general problem of defining the sentence and its role in the study of language. Mattoso Câmara\'s reflections about the sentence illustrate the movements of historical path of sentence idea. The same occurs with his retrospection horizon. The Chapters XI and XII of his Princípios de linguística geral (1st ed., 1941) are his contributions to the conceptual-terminological precision effort of sentence idea. He does so understanding the sentence\'s heteroclite character and its theoretical framework from the Saussurian dichotomy langue / parole. This work results from the survey of clues of sentence idea and the epistemological contexts in which they arise. Most of those clues was found in the work of Mattoso Câmara. The course of presence and problematization of sentence question in the long term of Western linguistic thought in the space-time axes of Greek Antiquity, Rationalist France, and Brazil that is modernized enables us to understand and locate in the history of Brazilian linguistic ideas the contribution of Mattoso Câmara to conceptualization of the term FRASE. The theoretical-methodological bias of this work is the History of Linguistic Ideas; it was proposal by the philosopher and historian Sylvain Auroux. The core of this theoretical-methodological proposal is the metalinguistic knowledge constituted and / or about to be constituted. They can be of four types: speculative, practical, technical and competent (AUROUX, 1988). The concept of sentence idea underlying this work results from the metalinguistic knowledge of a speculative nature, since it is from there that came the terms, in Portuguese, frase, sentença, oração, proposição, período e enunciado.

COMMON DETECTORS FOR TIER 1 MODULATIONS

Nelson, Tom, Perrins, Erik, Rice, Michael 10 1900 (has links)
ITC/USA 2005 Conference Proceedings / The Forty-First Annual International Telemetering Conference and Technical Exhibition / October 24-27, 2005 / Riviera Hotel & Convention Center, Las Vegas, Nevada / The ARTM Tier 1 waveforms include two versions of Feher patented QPSK (FQPSK-B and FQPSK-JR) and a version of shaped offset QPSK (SOQPSK-TG). In this paper we examine three common detector architectures for the ARTM Tier 1 modulations: a symbol-by-symbol detector, a cross correlated trellis coded modulation (XTCQM) detector, and a continuous phase modulation (CPM) detector. We show that when used to detect Tier 1 modulations, these detectors perform well even without knowledge of the modulation used by the transmitter. The common symbol-by-symbol detector suffers a loss of 1.5 dB for SOQPSK-TG and 1.6 dB for FQPSK-JR in bit error rate performance relative to the theoretical optimum for these modulations. The common XTCQM detector provides a bit error rate performance that is 0.1 dB worse than optimum for SOQPSK-TG and that matches optimum performance for FQPSK-JR. The common CPM detector achieves a bit error rate performance that is 0.25 dB worse than optimum for SOQPSK-TG and that approximately matches optimum for FQPSK-JR. The common XTCQM detector provides the best bit error rate performance, but this detector also has the highest complexity.

RECOMMENDED MINIMUM TELEMETRY FREQUENCY SPACING WITH CPFSK, CPM, SOQPSK, AND FQPSK SIGNALS

Law, Eugene 10 1900 (has links)
International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / This paper will present equations for calculating the minimum recommended frequency separation of two digital telemetry signals. The signals can be filtered continuous phase frequency shift keying (CPFSK), multi-h continuous phase modulation (CPM) [1], shaped offset quadrature phase shift keying-Telemetry Group (SOQPSK-TG, aka SOQPSK-A*) [2], or Feher’s patented quadrature phase shift keying FQPSK-B (or FQPSK-JR [3]). The equations are based on measured data in an adjacent channel interference (ACI) environment for filtered CPFSK (aka PCM/FM), multi-h CPM (or CPM for short), SOQPSK-TG, FQPSK-JR, and FQPSK-B. This paper is an extension of my 2001 and 2002 International Telemetering Conference papers on this topic [4, 5]. The quantity measured was bit error probability (BEP) versus frequency separation at a given signal energy per bit to noise power spectral density ratio (Eb/No). The interferers were CPFSK, CPM, SOQPSK-TG or FQPSK-B (-JR) signals. The results presented in this paper will be for a desired signal bit rate of 1 to 20 Mb/s, one interferer 20 dB larger than the desired signal (a few tests included two interferers), and various center frequency spacings, interfering signals, receivers, and demodulators. The overall ACI test effort has collected data sets at several bit rates and with one and two interferers. The results will be useful to system designers and range operators as they attempt to maximize the number of Mb/s that can be simultaneously transmitted with minimal interference in the telemetry bands.

En trumslagare för freden! : En kritisk granskning av Martin Luther King Jr:s ickevåldsideologi

Abrahamsson, Christoffer January 2014 (has links)
Den här uppsatsen är en kritisk analys av King och hans ickevåldsideologi. Uppsatsens syfte och avgränsning är att granska och redogöra för den ideologi som King genom sina tal, predikningar och övriga skrifter redogjorde för. Metoden jag använt mig av är att systematisera Kings ideologi för att därefter analysera den. Efter en kritisk granskning av Kings ickevåldsideologi står det klart att den är koherent, men att hans argumentation emellanåt är bristfällig. I synnerhet brister King vid en rimlighetsprövning.                       Kings ickevåldsideologi utgick från en teocentrisk världsbild med naturrättslig filosofi. Han menade att alla människor är skapade till Guds avbild och att alla människor har möjligheten att göra gott. Kings ickevåldsideologi grundar sig på aktivt motstånd där människan med kärleken som redskap och civil olydnad kan åstadkomma samhällsförändringar. Han tog tydligt avstånd från all typ av våldshandlingar och menade att våld aldrig medför en varaktig förändring, att våld är omoraliskt och ovärdigt en människa samt att ickevåld är det enda sättet att förändra samhällsproblem sett ur ett långsiktigt perspektiv. / The purpose of this Master thesis is to give an account of and review the ideology yhat King presented through his preaching, speeches and other sources. The metod I have chosen for this purpose is to systematize King’s ideology and the to critically analyze it. When doing so I have discoverd that King’s non-violent ideology is coherent, but that his argumentation is somewhat defective, especially when examing its plausibility.                      King’s non-violence ideology was based on a theocentric wordview and a natural law pholosophy. He tought that all men are created in the image of God and that all humans have the possibility to do good. King’s non-violence ideology is based on active resistance where people use love and civil disobedience as tools to enforce subversive changes. King was against all types of violent actions and stated that violence never leads to sustainable change, that violence is immoral and unworthy of any human. King also said that non-violence is the only way to combat societal problems in a long-term perspective.

Newspapers, frames & King : A qualitative framing analysis of how Martin Luther King Jr. was portrayed in three U.S. Newspapers & how this relates to the ESL classroom

Abdiladif, Abdullahi January 2019 (has links)
The aim of this piece of research is to analyze how Martin Luther King Jr. was portrayed in three U.S newspapers based on framing theory. Through the use of qualitative frame analysis, ten newspaper articles are studied from the period 20/04/1967-11/05/1967. The dates were selected in relation to King’s public opposition to the Vietnam war. The results show that the articles are in most cases characterized by a focus on difference of opinion, polemic responses, and appeals to MLK to stop opposing the war. When understood from the lens of framing theory, this way of writing has been termed the conflict frame. Furthermore, three classroom tasks related to the newspaper articles are suggested. These activities are based on the Swedish curriculum for teaching English as a second language, schema theory, and framing theory.

Validation of a New Concept for Measuring Respirable Dusts

Liu, Xiao 07 November 2018 (has links)
Sampling of airborne dust in industry is influenced by the potential health effects associated with human exposure. Health effects depend on mass concentration and particle size which influences the site of pulmonary deposition. Occupational diseases tend to be associated with dust deposition in specific regions of the respiratory tract. The ACGIH size selective TLVs are expressed in three forms: Inhalable Particulate Matter, Thoracic Particulate Matter, and Respirable Particulate Matter. In pneuomoconioses, the amount of dust deposited in the lungs can be estimated by sampling the respirable fraction. Dose-response relationships are derived by relating the health experience of workers to the extent of their exposure to respirable dust. It can be readily seen that validity of these relationships depends primarily on the accuracy of estimation of the exposure dose. Different sampling techniques, such as impactors, horizontal elutriators and cyclones were used for decades to estimate the exposure to respirable dusts. Cyclones have been the most widely utilized. However, the performance curve of the cyclone is considerably different from observed dust deposition data in the human alveolar compartment. Current methods of measuring respirable dust overestimate that dust fraction, which results in underestimating the agent’s toxicity in dose-response relationships. In this investigation, a new concept for sampling respirable dust was proposed and validated. The goal of this study was to design a combined impactor/cyclone device that provides better estimation of the amount of respirable dust. The objectives of this study were: 1) to calibrate ten single-stage impactors previously deigned and machined by Dr. Hammad, 2) to obtain the collection efficiency curves of ten impactor-cyclone combinations by superimposing the collection efficiency curves of impactors on the well-defined cyclone efficiency curve, and 3) to compare the combined efficiency curves to actual human alveolar deposition data, and thus validate this new concept for sampling of respirable dust. The experiment was conducted in a 20’’x20’’x20’’ aerosol testing chamber constructed from aluminum with a glass window. A LoveLace nebulizer with a nominal droplet size of 7 micrometers was used to generate fluorescent monodisperse polystyrene latex aerosols 0.5, 1, 2, and 3 micrometers in diameter. A Vilnius aerosol generator was used to generate fluorescent PSL dry powders 6 micrometers in diameter. The generated aerosols were collected on 37 mm polyvinyl chloride filters positioned after the impactors. Sample fluorescence was determined using a GloMax-Multi Jr fluorometer. Impactor efficiencies at the various sizes were used to construct the collection curves of impactors. Efficiency curves were subsequently superimposed on the cyclone efficiency curve to obtain the final efficiencies of the sampling devices. The results indicated that the cut-off diameters increased with impactor jet size. The new efficiency curves of the sampling devices had similar shapes to actual alveolar deposition as determined experimentally in human subjects. Actually they fell between actual alveolar deposition curves 2 and 4 seconds for mean residence times. The findings from this work can be applied to design a novel respirable dust sampler that provides a realistic estimate of pulmonary deposition to be used in dose- response relationships for the various mineral dusts encountered in general and mining industries. The under estimation of the dust toxicity associated with the current sampling methodology may be one of the reasons for continuous lowering of the TLV and PEL for silica.
