Sobre o leito vacilante: mudanças na geomorfologia fluvial em meados do século XX / About the wavering bed: changes on fluvial Geomorphology in the mid-20th century

Luiz Gustavo Meira Barros 01 December 2014 (has links)
Um momento chave para o entendimento da evolução da linhagem filogenética da Geomorfologia é o pós-Segunda Guerra Mundial, quando profundas transformações sociais, econômicas e culturais, contribuem para uma nova fase do pensamento científico, mais objetivo e pragmático, e é nesse momento em que a Geomorfologia americana passa por uma quebra de seu paradigma. A construção do conhecimento sobre os processos naturais é antiga e passa por uma série de evoluções ao longo da história, merecendo destaque o estabelecimento dos estudos a partir da revolução científica do século XVII, quando a Geologia começa a ser organizada como um corpo de conhecimento bem definido, e dentro dele, a Geomorfologia aparece como uma importante base de estudos sobre a evolução do relevo. A segunda metade do século XIX é dominada pela influencia de William Moris Davis, que através de seus estudos estabeleceu um modelo de evolução do relevo, denominado de Ciclo Geográfico, dominado por fases de acordo com o grau de transformação provocada pelos rios. Essa teoria, calcada em uma abordagem histórica e geológica, acaba sendo largamente utilizada nos Estados Unidos, Europa Ocidental (exceto Alemanha) e países de língua inglesa em geral. Porém em 1945 é publicado um artigo seminal de Robert E. Horton, que é considerado o ponto de mudança e quebra do paradigma davisiano, ao servir de base para uma série de grupos que desenvolvem uma leitura da Geomorfologia muito mais voltada para a análise de processos, com bases na engenharia e na física, sendo que esse novo enfoque costuma receber o nome de Geomorfologia quantitativa. Dois grupos se destacam nessa transformação, um organizado por Arthur N Strahler, da Universidade de Columbia; e outro constituído por pesquisadores da USGS, unidos pela figura de Luna Leopold. Durante a década de 50 e 60 esses grupos publicaram uma série de artigos e livros que acabam por influenciar os estudos da Geomorfologia fluvial até os dias atuais, buscando a construção de um novo paradigma pós-davisiano, baseado na utilização da linguagem matemática e na formulação de leis, numa clara inspiração nos preceitos do positivismo lógico, inaugurando assim uma nova fase na Geomorfologia, que ainda mantem algumas características estabelecidas nesse período. / A key point for understanding the evolution of phylogenetic lineage of Geomorphology is the post-World War II, when profound social, economic and cultural transformations, contribute to a new phase of scientific thought, more objective and pragmatic, and that is when the American geomorphology involves a breach of its paradigm. The construction of knowledge about natural processes is old and undergoes a series of changes throughout history, with emphasis the establishment of studies from the scientific revolution of the seventeenth century, when the geology begins to be organized as a body of knowledge well defined, and within it, geomorphology appears as an important foundation for studies on the evolution of relief. The second half of the nineteenth century is marked by the influence of William Moris Davis, who through their studies established a model for the evolution of relief, named Geographic cycle, dominated by stages according to the degree of transformation caused by rivers. This theory, based on a historical and geological approach ends up being widely used in the United States, Western Europe (excluding Germany) and English-speaking countries in general. But in 1945 is published a seminal article by Robert E. Horton, who is considered the turning point and breaks of the davisian paradigm, to serve as the basis for a number of groups who develop a reading of Geomorphology much more focused on process analysis with bases in engineering and physics, and this new approach is usually given the name of \"quantitative geomorphology. Two groups stand out in this transformation, one organized by Arthur N Strahler, Columbia University; and another consisting of researchers from the USGS, united by the figure of Luna Leopold. During the 50s and 60s these groups published a series of articles and books that end up influencing the study of fluvial geomorphology to the present day, seeking the construction of a new post-davisian paradigm, based on the use of mathematical language and formulation of laws, a clear inspiration in the precepts of logical positivism, thus inaugurating a new phase in Geomorphology, which still maintains some characteristics established in this period.

A crise orgÃnica do capital: o valor, a ciÃncia e a educaÃÃo / The Organic Crisis of Capital: Value, Science and Education

Aluisio Pampolha Bevilaqua 23 July 2015 (has links)
Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico / O trabalho de pesquisa, sob o tÃtulo A Crise OrgÃnica do Capital: o Valor, a CiÃncia e a EducaÃÃo, sustenta em tese que o conceito de capital à a expressÃo da relaÃÃo social dominante na sociedade capitalista e, como tal, ao atingir seu momento dialÃtico de autonegaÃÃo â a crise do capital â redefine o carÃter da categoria crise como conceito orgÃnico, estrutural e histÃrico, exteriorizando-se na economia, como crise do valor; na ciÃncia, como crise de paradigma; e, na educaÃÃo, como crise pedagÃgica. Sob o mÃtodo dialÃtico do materialismo histÃrico, auxiliado pela epistemologia e matemÃtica aplicada, a pesquisa qualitativa foca-se principalmente na obra de Marx e, secundariamente, na literatura contemporÃnea marxista e nÃo marxista, documentos e estatÃsticas oficiais. O objetivo à demonstrar que as crises da economia mundial, das Ãltimas dÃcadas do sÃculo XX e as do sÃculo atual, constituem momentos e expressÃes singulares de uma crise geral ou global, cuja essÃncia causal à a erosÃo da Lei do Valor, precisamente, do paradigma de mensuraÃÃo do valor - o tempo de trabalho socialmente necessÃrio - na estrutura da composiÃÃo-valor ou orgÃnica do capital e mais-valia sobre a qual orbitam as relaÃÃes de produÃÃo e reproduÃÃo da sociedade capitalista. A crise final ou o colapso do capitalismo continuam sendo problemas e enigmas nÃo resolvidos pela teoria marxista, cuja resoluÃÃo exige uma reinterpretaÃÃo conceitual da Lei Geral da AcumulaÃÃo Capitalista que ultrapasse a teoria do ciclo econÃmico e chegue à teoria da crise estrutural, orgÃnica e histÃrica do capital. Nos Grundrisse, Marx afirmou que o domÃnio do general intellect e do knowledge social geral sobre o processo de produÃÃo e vida social implicaria a estreiteza do tempo de trabalho socialmente necessÃrio para mensurar a ciÃncia e a educaÃÃo na composiÃÃo-valor do capital. A pesquisa demonstra que isto hoje à um fato, daà o carÃter decisivo destas categorias no agravamento e superaÃÃo da crise orgÃnica do capital. O duplo carÃter destas atividades dos sujeitos histÃricos conduz, por um lado, ao paroxismo a contradiÃÃo entre o valor do conhecimento ou intelecto geral e o paradigma de mensuraÃÃo de valor; por outro, à anÃlise lÃgica e histÃrica entre a revoluÃÃo industrial, ou cientÃfica, e o desenvolvimento do aparelho produtivo capitalista; o que demonstra a subordinaÃÃo da ciÃncia e da educaÃÃo aos desÃgnios da economia polÃtica do capital e, em consequÃncia, a crise de paradigmas vividas por ambas como indicam documentos e estatÃsticas das instituiÃÃes internacionais e trabalhos cientÃficos. Finalmente, a tese propÃe a construÃÃo de nÃcleos estratÃgicos e experimentais de formulaÃÃo pedagÃgica com base no paradigma do tempo livre na formaÃÃo humana, como aÃÃo prÃ-ativa à revoluÃÃo cientÃfica e social. / The research, entitled The Organic Crisis of Capital: Value, Science and Education, in theory maintains that the concept of capital is the expression of the social relation that dominates capitalist society and, as such, when its dialectic moment of self-denial is reached - the crisis of capital -, the character of the category crisis is redefined as an organic, structural and historical concept, externalizing itself in the economy, as crisis of the value; in science, as a paradigm crisis; and in education, as a pedagogical crisis. Under the dialectical method of historical materialism, aided by epistemology and applied mathematics, the qualitative research focuses primarily on the work of Marx and secondarily in Marxist and non-Marxist contemporary literature, documents and official statistics. The purpose is to demonstrate that the crisis in the global economy of the last decades of the twentieth century and of the present century, are singular moments and expressions of a general or global crisis, whose causal essence is the erosion of the Law of Value, precisely of the value measurement paradigm - the socially necessary labor time - the structure of the value composition, or organic composition of capital and surplus value over which orbit the relations of production and reproduction of capitalist society. The final crisis or the collapse of capitalism are still problems and puzzles unsolved by Marxist theory whose resolution requires a conceptual reinterpretation of the General Law of Capitalist Accumulation that surpasses the business cycle theory and enter into the theory of the structural, organic and historical crisis of capital. In the Grundrisse, Marx said that the domain of the general intellect and general social knowledge over the production process and social life would result in the narrowness of the socially necessary labour time to measure science and education in the value composition of capital. The research evinces that this is now a fact, thus the decisive character of these categories in the organic crisis of capital aggravation and overcoming. The double character of those activities of the historical subjects leads, on the one hand, the contradiction between the general intellect or knowledge value and the value measurement paradigm to the paroxysm; on the other hand, leads to the logical and historical analysis between the industrial, or scientific, revolution and the development of the capitalist mode of production; this demonstrates the subordination of science and education to the purposes of the political economy of capitalism and, consequently, the crisis of paradigms experienced by both as indicated by documents and statistics of international institutions and scientific papers. Finally, the thesis proposes the construction of strategic and experimental centers of pedagogical based on the free time paradigm in the human formation, as proactive action to the scientific and social revolution.

Verbos defectivos no português brasileiro: eles existem mesmo? / Defective verbs in Brazilian Portuguese: Do they really exist?

Klauber Renan Dutra de Oliveira 19 September 2017 (has links)
Nesta dissertação, os verbos considerados defectivos pela normatividade são o objeto de estudo em questão. O objetivo consiste em averiguar se verbos, como banir, explodir, demolir, precaver, reaver, dentre outros são usados defectivamente pelos falantes. Para isso, nós analisamos e estudamos o conceito de defectividade em autores da tradição brasileira, como Cunha & Cintra (2008), Bechara (2009) e em autores que estudaram a defectividade no português brasileiro por meio de teorias linguísticas, como Nevins, Damulakis e Freitas (2014) e Maiden & ONeil (2010). Vimos que esses autores apontam causas da defectividade por questões fonológicas, morfológicas, semânticas e pragmáticas. Outros trabalhos que não tinham paradigmas verbais no português brasileiro foram fundamentais para o andamento desta pesquisa, como Baerman (2010) e Sims (2006). Dentre esses estudos analisados, procuramos abordar quais as causas identificadas pelos autores citados, dentre elas, encontramos a homofonia como um senso comum. Tratamos nossos dados dentro da teoria da gramática gerativa, como a teoria da otimalidade. Durante a nossa pesquisa, vimos que o fenômeno da defectividade ocorre de maneira desigual, pois, em alguns paradigmas verbais, falta apenas a primeira pessoa do singular do presente, enquanto em outras o paradigma apresenta apenas as formas arrizotônicas. Reanalisamos dados de pesquisas anteriores do ponto de vista fonológico, morfológico e semântico para mostrar alguns problemas nelas. Nosso estudo foi motivado porque encontramos dados os quais mostram que verbos ditos defectivos pela gramática tradicional são conjugados plenamente pelos falantes nativos. Logo, a fim de averiguar se o falante usa os mesmos verbos defectivamente como a gramática, fizemos alguns experimentos para isso. Os nossos resultados mostraram indícios de que a defectividade é vista de uma forma diferente pelo falante, pois há uma incompatibilidade parcial entre o que a gramática diz e entre o que o falante usa. / The verbs considered defective by normativity are the object of study in this thesis. The goal is to verify if verbs such as: ban, explode, demolish, preclude, retrieve, amongst others are used by the speakers defectively. To do so, we analyzed and studied the defectiveness concept in authors from the Brazilian tradition, such as Cunha & Cintra (2008), Bechara (2009), and in authors that have studied defectiveness in Brazilian Portuguese through other linguistic theories, such as Nevins, Damulakis and Freitas (2014) and Maiden & ONeil (2010). We have perceived that these authors point out reasons for defectiveness for phonologic, morphologic, semantic and pragmatic reasons. Other works that did not have Brazilian Portuguese verbal paradigms were fundamental for the development of this research, such as Baerman (2010) and Sims (2006). Amid the analyzed studies, we sought to approach the identified causes mentioned by the quoted authors, among them, we found the homophony as a common ground. We approached our data within the generative grammar theory, as well as the optimality theory. During our research, we saw that the defectiveness phenomenon happens in an uneven way because, in some verbal paradigms, there is only the present first-person singular missing, while in others, the paradigm presents only the forms with no stressed root. We reanalyzed the data from previous researches from the phonologic, morphologic and semantic point of view to present some of their problems. Our study was motivated by finding data that showed us that some verbs considered defective by the traditional grammar are fully conjugated by native speakers. Therefore, with the intent to verify if the speaker uses the same verbs defectively as the grammar, we made some experiments. Our results showed indications that the defectiveness is seen in a different way by the speaker, because there is a partial incompatibility between what is said by the grammar and what is used by the speaker.

Uma hipótese de Werner Heisenberg e o sentimento de solidão humana determinado pelo impacto das mudanças na explicação do cosmos. Um estudo a partir de representações sociais na literatura ocidental / One hypothesis of Werner Heisenberg and the human lonely by the impact of the changes in the explanation of the Cosmos. A study from social representation in the Ocidental Literature

Raquel Aparecida Tonolli Jacob 06 August 2010 (has links)
Nossa Tese visa explorar as implicações da hipótese de Werner Heisenberg na literatura segundo a qual na medida em que a Cosmologia progride no sentido da matematização e da axiomatização esse conhecimento vai se afastando do ser humano e transformando a idéia que ele sempre fez da própria natureza que o cerca. Assim, passaria a existir nesse homem uma verdadeira solidão referente ao estar no mundo. Num primeiro momento ele soube que a Terra não é mais o centro do Universo, (inversão copernicana) depois que poderia não ser mais filho de Deus (teoria da evolução) e, finalmente, nem mesmo pode ter uma idéia fiel da natureza, mas na realidade só lhe resta alcançar um conhecimento matemático que exprima essa natureza, muito diferente daquela na qual sempre viveu. (física subatômica). Poucos são os que tomam conhecimento dessas mudanças no mundo da Física em geral e da Cosmologia, em particular. No entanto, o grande pensador da Psicologia Social, Serge Moscovici, cria o conceito de Representação Social que explica o fenômeno identificável na literatura. O homem comum não estuda e não entende os meandros da Física ou da Cosmologia, mas esse conhecimento chega a ele, ainda que distorcido, trocado em miúdo, como representação social, transmitida pelos divulgadores com maior ou menor grau de entendimento, por intermédio de livros, cinema e comentários em geral; hoje em dia, até pela televisão, ou jornais. Essas mudanças no âmbito da ciência certamente são interpretadas, pela grande maioria dos estudiosos, como mudanças de paradigma. Mas nós adotaremos aqui, o conceito de paradigma de Gilles Gaston Granger. Para Granger, um exemplo típico de mudança de paradigma nas Ciências exatas é aquela que ocorreu na passagem da Física de Aristóteles à Física de Galileu. Aqui realmente há quebra de paradigma, descontinuidade e incomunicabilidade entre eles. Mudou o modelo de Ciência, mudaram todos os conceitos que foram redefinidos no âmbito do novo paradigma. Já as mudanças que ocorrem no domínio da Física, a partir de Galileu, quando se fala em mudança de paradigma, fala-se, em geral, em restrição de um conceito, ou se quisermos, ampliação de um conceito, mas não de ruptura completa ou de incomunicabilidade com o paradigma anterior. Tratar-se-ia então da criação de novos sub-paradigmas. Paradigma, na acepção kuhniana do termo, Granger aceita apenas para as proto-ciências, nas quais podemos falar de ruptura e de incomunicabilidade; como ocorre na Psicologia se considerarmos suas várias teorias. É preciso que se diga que com os avanços dos experimentos a incomunicabilidade começa a ser quebrada. Escolhemos a literatura como uma das formas de verificar o impacto da mudança cosmológica sobre a psique humana, mas poderíamos ter escolhido a arte pictórica ou outra expressão do homem na interpretação do mundo. Confrontamos obras clássicas com a visão aristotélica/ptolomaica e as obras literárias do século XIV com a visão de Copérnico e Galileu. Posteriormente procuramos mostrar o impacto do salto da idéia que o ser humano tinha da natureza com Kepler, Galileu e Newton para a representação da natureza com o advento da Física sub-atômica e sua repercussão em textos literários de significação consagrada pelos grandes críticos e analistas da literatura ocidental / Our Thesis aims to explain the implications of the Werner Heisenbergs hypothesis in literature, according to which this knowledge stands off from man in proportion to Cosmology progresses to mathematization and axiomatization and transforms the idea that he always had about the nature that surrounds him. Thus, it would exist in this man a true solitude feeling of being in the world. In the first moment he discovered that Earth isnt anymore the center of Universe (Copernican inversion), then that he could be no longer the son of the God (evolution theory) and finally that he could not even have a true idea of nature, but that in reality it only remains a mathematical knowledge which expresses this nature very different of that in which he had always lived (subatomic physics) - to be done. Few are those who take knowledge of these changes in Physics in general and Cosmology in particular. However, the great thinker of Social Psychology, Serge Moscovici, creates the concept of Social Representation, which explains the identifiable phenomenon in literature. The common man doesnt study and doesnt understand the meanders of Physics and Cosmology, but this knowledge reaches him, even though distorted, made simple, as social representation, transmitted by the scientific publicizers with more or less understanding through books, cinema and comments in general; nowadays, even through TV or newspapers. These changes in the extent of science certainly are interpreted by the great majority of experts as paradigm shifts. We will adopt here, however, Gilles Gaston Grangers concept of paradigm. For him, a typical example of paradigm shift in the Exact Sciences is the one that occurred in the passing from Aristotelian Physics to Galilean Physics. Here we actually have a paradigm rupture, discontinuity and incommunicability between them. The Science model changed, all the concepts changed, redefined in the scope of the new paradigm. About the changes that occur in the domain of Physics, since Galileo, when we discuss paradigm shift we discuss, generally speaking, a restriction of a concept, or, if we want, enlargement of a concept, but not of complete rupture or incommunicability with the anterior paradigm. It would be about the creation of new sub paradigms. Granger accepts the usage of paradigm in the kuhnian acceptation of the term only for the protosciences, for which we can speak of rupture and incommunicability; as it occurs in Psychology, if we consider its various theories. It must be said that with the experiments advances the incommunicability begins to be broken. We have chosen literature as one of the ways of verifying the cosmologic change impact upon the human psyche, but we could have chosen pictorial art or other human expression in the interpretation the world. We confront classic oeuvres with Aristotelian or Ptolemaic point of view and 15th century literary oeuvres with Copernican and Galilean point of view. Posteriorly we tried to demonstrate the impact of the leap of the idea that the man had about nature with Kepler, Galileo and Newton to the nature representation with the advent of Subatomic Physics and the representations about it in literary texts consecrated by Western Literature important critics and analysts

The link between fixation location and attention during reading : its extent and nature

Wakeford, Laura Jane January 2015 (has links)
This thesis explores the relationship between fixation location and the locus of attention during reading. Early theories of eye movement control during reading suggested that a very tight coupling exists between the two (Just & Carpenter, 1980); however, it has since been shown that dissociations do exist. Whether these dissociations necessarily implicate parallel lexical processing, or whether they can be accommodated for within a serial-sequential framework is explored in a series of experiments. Experiment 1 tested whether parallel lexical processing is, at the very least, psychologically plausible. Two horizontally aligned letter strings were presented simultaneously on a screen, the task being to decide whether they were physically identical or not. Even when presentation duration should have been short enough to prohibit the strictly serial processing of each word in turn, the results show clear lexical effects: high frequency words were responded to faster and with fewer errors than low frequency words. Effects of lexicality and orthography were also found. These results suggest that the two words had been processed at a lexical level in an overlapping fashion. Experiments 2 and 3 investigated the nature and range of word n+2 preview effects. In Experiment 2, word n+1 was either a determiner or 3-letter alternative higher frequency word; in Experiment 3, word n+1 was either a 4- or a 6-letter high frequency word. A gaze contingent display change technique was employed, where prior to passing an invisible boundary located immediately after word n, one, the other, neither or both of words n+1 and n+2 received a nonword preview. In addition to showing orthographic parafoveal-on-foveal effects stemming from word n+1, there was also evidence that word n+2 preview influenced targeting decisions on words n and n+1. Word n+2 preview effects are also found on word n+2 and in the spillover region. These effects were most wide ranging when word n+1 length was an average of 5- compared to 3-letters. Higher-level plausibility preview effects were explored in Experiments 4-6, again using a gaze contingent display change technique. In Experiment 4 word n+1 received either an identical preview, a different but plausible one, or an anomalous, or nonword preview. Critically, an effect of plausibility arose on word n+1, with anomalous previews receiving longer inspection times than alternative plausible previews. Experiments 5 and 6 investigated the range over which these effects might occur, testing for a plausibility preview effect on word n+2. Results showed numerical, but not statistical evidence for a plausibility-related preview effect on word n+2. There were, however, clear orthographic word n+2 preview effects. Finally, Experiment 7 experimentally tested the immediate oculomotor response to a mislocated fixation, using a text shift paradigm to simulate saccadic error and measuring the effect on lexical processing. Critically, this experiment showed that a quick error correction strategy appears to be engaged following a simulated saccadic undershoot, rather than a stay and process response. This suggests that a mislocated fixation account coupled with a stay and process response is unlikely to provide a viable explanation for lexical parafoveal-on-foveal effects. Overall, it is suggested that current instantiations of both serial (e.g., Reichle, Warren & McConnell, 2009) and parallel (e.g., Schad & Engbert, 2012) models of eye movement control during reading appear to fail to capture major aspects of these patterns of results. The results do, however, appear to fit most parsimoniously with a perspective on eye movement control that allows for multiple words to be processed in an overlapping fashion.

The way to make cities smarter : evidences from Europe

Camboim, Guilherme Freitas January 2018 (has links)
As cidades industriais ainda mantêm estruturas para uma dinâmica de produção e consumo em massa, que resultam em vários problemas, como desemprego, falta de moradia, engarrafamentos, poluição, doenças, violência e entre outros. Esta configuração industrial urbana já não está mais condizente com os princípios de criação de valor do novo paradigma do século XXI. A dinâmica do novo paradigma técnico-econômico exige que as cidades resgatem sua própria essência, que é a de aproximar pessoas para interagirem e compartilhar ideias e conhecimentos de modo que seja possível iniciar um novo ciclo de criação de riqueza. Para superar essa crise e entrar nesta nova dinâmica, as cidades do futuro devem encontrar trajetórias adequadas para se tornarem cidades inteligentes. No entanto, não há consenso sobre o que realmente torna uma cidade mais inteligente. O que é uma cidade inteligente? Quais são os elementos que podem aumentar a inteligência de uma cidade? O objetivo deste estudo é propor uma estrutura integrada para entender o processo de tornar as cidades mais inteligentes Para atingir este objetivo, foi realizado uma revisão sistemática da literatura para definição do conceito e também um estudo de casos múltiplos de projetos de cidades inteligentes em quatro cidades europeias (Amsterdã, Barcelona, Lisboa, Viena) onde alguns especialistas foram entrevistados. Os resultados mostraram que as cidades para se tornarem mais inteligentes devem integrar suas dimensões e elementos, a fim de oferecer alta qualidade de vida e um ambiente próspero para inovação e criatividade da maneira mais sustentável. Se uma cidade deseja iniciar esse processo de transformação, deve desenvolver projetos específicos que utilizem e melhorem sua configuração ambiental urbana, sua dinâmica tecno-econômica e sua estrutura sócio institucional, a fim de criar riqueza através de um abrangente processo de inovação. Portanto, o desafio de tornar uma cidade mais inteligente está em definir como articular adequadamente esses elementos direcionadores de cada dimensão, a fim de construir seu próprio ecossistema urbano de inovação. / Industrial cities still maintain structures for a mass production and consumption dynamics, which result in several issues such as unemployment, homeless, traffic jams, pollution, diseases, violence and so on. This urban industrial configuration no longer fits with the value creation principles of the new techno-economic paradigm. The dynamics of the new techno-economic paradigm demand that cities redeem their very essence in order to start a new cycle of wealth creation. In order to overcome this crisis and encompass this new dynamics, cities of the future must find suitable trajectories to become smart cities. However, there is no consensus about what really makes a city smarter. What is a smart city? What are the driving elements that can enhance the smartness of a city? The objective of this study is to propose an integrated framework in order to understand the process to make cities smarter To achieve this objective, it was realized a systematic literature review and a multiple case studies from smart cities projects in four European cities (Amsterdam, Barcelona, Lisbon, Vienna) where some experts were interviewed. Results show that cities to become smarter should integrate their dimensions and elements in order to offer high quality of life and a prosperous environment for innovation and creativity in the most sustainable way. If a city wants to start this process of transformation, it should develop some specific projects that that use and improve its enviro-urban configuration, its techno-economic dynamics and its socio-institutional structure in order to create wealth through a comprehensive innovation process. Therefore, the challenge to make a city smarter lies on defining how to articulate those driving elements in each dimension properly in order to build up its own urban innovation ecosystem.

Entre o empirismo e a teoria : uma análise da produção científica nacional sobre comportamento eleitoral (1956-2014)

Ribas, Vinicius de Lara January 2015 (has links)
A dissertação de mestrado analisa os artigos publicados a respeito do Comportamento Eleitoral no Brasil em periódicos científicos com impacto nacional. Para tal, discute os primeiros trabalhos publicados, datados do fim dos anos 50, até os dias atuais, em revistas nacionais de Qualis A1 e A2. O trabalho discute a evolução das teorias de explicação do voto na ciência política brasileira e tem como argumento principal que os estudos sobre o comportamento eleitoral foram cruciais para a construção da autonomia acadêmica da disciplina e a introdução e difusão do paradigma comportamentalista, ajudando a construir uma Ciência Política no Brasil que se preocupa com a análise empírica e a quantificação. Entretanto, as revistas que servem de plataforma para as publicações, os pesquisadores e seus vínculos institucionais mostram que há uma concentração dessa linha de pesquisa e da produção em instituições de pesquisa da região Sudeste. Também há uma concentração moderada no tipo de abordagem utilizada, pois predomina a explicação psicológica e, em segundo lugar, estudos de geografia eleitoral. Ao analisarmos o desenvolvimento teórico dos estudos publicados no formato artigo em revista, defendemos que a próxima etapa da construção da autonomia acadêmica da disciplina, pelo menos no que se refere à subárea de estudos de comportamento eleitoral, é a descentralização dos meios de produção científica – revistas, editoras, etc. – e a própria produção científica, assim como o aumento do pluralismo teórico e metodológico no estudo desse tema. / The master's thesis analyzes the articles published about the Voting Behavior in Brazil in scientific journals with national impact. As such, it discusses the first published works, dating from the late 50s until the present day, in national journals Qualis A1 and A2. The paper discusses the evolution of theories of vote explanation in Brazilian political science and its main argument is that the studies on voting behavior were crucial to the construction of the academic autonomy of discipline and the introduction and dissemination of the behaviorist paradigm, helping to build a political science in Brazil that cares about the empirical analysis and quantification. However, the magazines that serve as a platform for publications, researchers and their institutional links show that there is a concentration of such research and the production line at research institutions in the Southeast. There is also a moderate concentration in the type of approach used, as predominates the psychological explanation and, secondly, electoral geography studies. By analyzing the theoretical development of the studies published in article magazine format, it is argued that the next stage of construction of the academic autonomy of the subject, at least in regard to the subfield of electoral behavior studies is the decentralization of scientific production means - magazines, publishing houses, etc. - And the scientific production itself, as well as the increase of the theoretical and methodological pluralism in the study of this subject.

Contribui??es da agroecologia para a transi??o paradigm?tica: o caso da Caravana Agroecol?gica e Cultural do Rio de Janeiro

No. of bitstreams: 1 2017 - Mariana Telles Rocha.pdf: 1081497 bytes, checksum: ca49dd03a2afea90b84ff4c91dbf2f76 (MD5) Previous issue date: 2017-05-29 / The paradigm of modern science has been questioned since its inception, and more broadly and profoundly in this century. There are some proposals to rethink it as a whole, relying on several theoretical-practical essays on how to emerge a different paradigm. For that, we will have different ontologies, epistemologies and methodologies, we will enunciate them from multiple places. This allows the existence of multi-faceted looks, reframing the notions of neutrality, rationalism, dualism, reductionism, one-sidedness as the only way to build a truly scientific knowledge. One of these places of enunciation is agroecology, currently recognized as science, social movement, practice, way of life, utopia, government policy, profession, formal education modality, ideology. In order to discuss these different definitions and practices in agroecology, in an attempt to interact and multiply efforts, a perspective that is being used and strengthened by collectives and individuals is the networking and construction of gift networks. To leave the modern paradigm of science and arrive at another under construction, it is necessary to consider the process of transition. Understanding the political character of scientific activity, taking into account the indissociability between teaching, research and extension, agroecology uses a series of methodologies to build agroecological knowledge, seeking to foster dialogue between different knowledge that are equally incomplete. One of the methodologies used is the agroecological and cultural caravans, which has a series of horizontal communication tools such as artistic pedagogical installations, graphic facilitation, and collaborative communication. The sources used for its conception were, among others, the experiences of peasant-to-peasant methodologies, caravans of citizenship, and pilgrimages of the land. We notice the need to consider the psychological structures in the understanding of the interaction and the relationship of this with the structure of society and with the structure of history. Through the moments and spaces built by the ?Comboio Agroecol?gico Sudeste? network, it was possible to see the relationships between the individual, the methodology, the epistemology in the construction of the paradigm of agroecology, and how the agroecological and cultural caravan contributes to the emergence of a new form of building knowledge. In order to deepen and to highlight the clues of this paradigm transition, it is necessary to understand i) whether and how we are moving from cartesian science to a systemic, complex, agroecological, post-normal, postmodern, and / or decolonial science; ii) whether and how we are moving from a state of automatic unconsciousness, which reproduces patterns, which does not assume commitments, to a state of individuation, a "Greater Being" committed to itself and to the collectives iii) how and if the network, through the Caravan of Rio de Janeiro, promoted the dialogue of knowledge in the construction of agroecological knowledge; is therefore to verify if and how we are polishing the lenses of seeing, feeling, thinking, intuiting and being in the world. Some categories emerged from the content analysis and collected interviews conducted to answer these questions. From the construction, realization and evaluation of the agroecological and cultural caravan of Rio de Janeiro, it was possible to verify the paradoxical and complex nature of reality, and the different understandings about what is supposedly a same event, process and a same methodology. / O paradigma da ci?ncia moderna vem sendo questionado desde seus prim?rdios, e mais ampla e profundamente neste s?culo. Existem algumas propostas para repens?-lo como um todo, contando com v?rios ensaios te?rico-pr?ticos de como emergir um paradigma diferente. Para tanto, contaremos com diferentes ontologias, epistemologias e metodologias, as enunciaremos de m?ltiplos lugares. Isso permite ? exist?ncia de olhares pluriversais, ressignificando as no??es de neutralidade, racionalismo, dualismo, reducionismo, unilateralidade como ?nico caminho de construir um conhecimento verdadeiramente cient?fico. Um desses lugares de enuncia??o ? a agroecologia, reconhecida atualmente como ci?ncia, movimento social, pr?tica, modo de vida, utopia, pol?tica governamental, profiss?o, modalidade de educa??o formal, ideologia. Para dialogar essas diferentes defini??es e pr?ticas na agroecologia, na tentativa de interagir e multiplicar esfor?os, uma perspectiva que vem sendo utilizada e fortalecida pelos coletivos e indiv?duos ? a atua??o em rede e constru??o das redes de d?divas. Para sair do paradigma moderno de ci?ncia e chegar a outro em constru??o, ? necess?rio considerarmos um processo de transi??o. Entendendo o car?ter pol?tico existente na atividade cient?fica, levando em considera??o a indissociabilidade entre ensino, pesquisa e extens?o, a agroecologia lan?a m?o de uma s?rie de metodologias para construir o conhecimento agroecol?gico, buscando fomentar o di?logo entre os diferentes saberes que s?o igualmente incompletos. Uma das metodologias utilizadas s?o as caravanas agroecol?gicas e culturais, que conta com uma s?rie de ferramentas de comunica??o horizontal como as instala??es art?sticas pedag?gicas, facilita??o gr?fica, comunica??o colaborativa. As fontes utilizadas para sua concep??o foram, entre outras, as experi?ncias das metodologias campesino-a-campesino, caravanas da cidadania, e romarias da terra. Notamos a necessidade de considerar as estruturas psicol?gicas no entendimento da intera??o e da rela??o desta com a estrutura da sociedade e com a estrutura hist?ria. Atrav?s dos momentos e espa?os constru?dos pela rede do projeto Comboio Agroecol?gico Sudeste, foi poss?vel enxergarmos as rela??es entre o indiv?duo, a metodologia, a epistemologia na constru??o do paradigma da agroecologia, e como a caravana agroecol?gica e cultural contribui para a emerg?ncia de uma nova forma de construir o conhecimento. Para aprofundar e evidenciar as pistas dessa transi??o de paradigmas, ? necess?rio entender i) se e como estamos transitando da ci?ncia cartesiana para uma ci?ncia sist?mica, complexa, agroecol?gica, p?s-normal, p?s-moderna, e/ou descolonial; ii) se e como estamos transitando de um estado de inconsci?ncia autom?tica, que reproduz padr?es, que n?o assume compromissos, para um estado de individua??o, um ?Ser Maior? compromissado com si mesmo e com os coletivos; iii) como e se a rede, atrav?s da Caravana do Rio de Janeiro, promoveu o di?logo de saberes na constru??o do conhecimento agroecol?gico; ?, portanto, verificar se e como estamos polindo as lentes de ver, sentir, pensar, intuir, ser e estar no mundo. Algumas categorias emergiram da an?lise de conte?do e entrevistas coletadas, realizadas para responder essas quest?es. A partir da constru??o, realiza??o e avalia??o da caravana agroecol?gica e cultural do Rio de Janeiro, foi poss?vel verificarmos a natureza paradoxal e complexa da realidade, e os diversos entendimentos acerca do que ? supostamente um mesmo acontecimento, processo e uma mesma metodologia.

The use of social gaze cues in real world scenes

Mitchell, Kathryn Mary Anne January 2015 (has links)
Eyes are an ideal tool for investigating social attention, as their physiological composition with the iris and pupil highly-distinguishable against the white sclera, combined with our foveated vision, mean that gaze cues are both a means of understanding where attention is being allocated and a method for non-verbal communication. Previous attention research using gaze cues has focused on Posner-type paradigms that have supported a model of reflexive orienting of attention in response to gaze cues. However, the ecological validity of this type of paradigm has been called into question given more recent real world research, which has produced findings that cannot be explained by laboratory-based Posner-type paradigms. Therefore, the aim of this thesis was to develop and test a novel, more ecologically-valid paradigm that could investigate observers’ responses to gaze cues in a realistic, but controlled, manner. Based on past research, an initial goal of this research was to develop an early iteration of a realistic visual search paradigm in which a single non-predictive gaze cue is presented. This was built on in later chapters by adding manipulations of task instruction. These chapters presented some evidence that supported a reflexive orienting model of gaze, with clear facilitation to performance as a result of person presence. The second goal of this research was to explore observers’ responses when presented with the same task and search arrays, but with the inclusion of a second gaze cue. This is some of the first research to address multiple gaze cues within a realistic visual search paradigm. These chapters showed multiple gaze cues result in quite considerably different observer eye movement behaviour. Benefits of people presence were stronger and far more congruency effects were apparent. There were also clear effects of instruction, with the suggestion that gaze cues provided may be helpful to the task resulting in significantly greater proportions of overt gaze-seeking than in other instruction conditions. The introduction of multiple gaze cues created a new gaze cue condition – the conflicting condition in which each person cued separate spatial areas within the scene. In order to explore the effects of gaze cue sender reliability on observers’ eye movements, a third version of the study was tested where the gaze cues presented were spatially informative, cuing the target in 70% of trials. Results showed similar benefits of people presence to the previous multiple-cue chapters, but there were minimal reliability effects. Methodological adaptations were suggested based on previous research that has explored reliability effects that may more successfully elicit reliability effects in future research. The final chapter presents a summary of the findings of the research contained within this thesis. The results showed that in a more complex and realistic visual search task employing a single gaze cue, results are somewhat consistent with the reflexive orienting model of gaze due to the clear facilitation as a result of person presence and the lack of instruction effects. The findings presented also demonstrate that once multiple gaze cues are introduced, the reflexive orienting model cannot account for observers’ gaze behaviour. Instead, findings are more consistent with recent real world research. This would suggest that a new model of gaze processing is required when more than one gaze cue is presented, and the final chapter offers some suggestions of what this new model would need to take into account. It is suggested that subsequent research using this novel paradigm should explore the use of dynamic cues and the effects on eye movement behaviour in special populations, and that the research presented in this thesis provides a solid foundation upon which these new directions for research can be built.

Mental Health Treatment for the Elderly Community in a Central California Region

Klevins, John Lewis, Mr. 01 June 2018 (has links)
There is a national, state and local concern that focuses upon the rapid growth of our elder population as well as those within the cohort that suffer with mental illness. However, other than the numerous Alzheimer’s related headlines, there is little national or state consideration being given to non-dementia-related elder mental illnesses. The lack of existing mental health service programs to assist the elderly community merits attention. The Constructionist paradigm was the basis for this study, due to its reliance upon recognized leaders in the field engaging in an interactive group process. These leaders included politicians, governmental agencies, non-profit organizations, and other community leaders. Outcomes from this study produced five action oriented initiatives: Leadership, Funding Campaign, Elder Sensitivity Campaign, Enhancement of Existing Programs, and New Program Expansion. These initiatives, if implemented, could drive change and positively affect the elderly population with mental illness within this central California county research site.
