Web 2.0 : uma análise evolucionária do seu impacto nas empresas a nível global

Valdez Montalván, Daniel Borja January 2010 (has links)
O objetivo principal desta dissertação é analisar as tecnologias de aplicativos da Web 2.0, desde uma perspectivas evolucionária, e dos seus impactos nas empresas em nível global. Desta forma, para poder entender o seu nascimento, essência e importância econômica para as empresas, se tomou como base teórica o conceito evolucionário de revoluções tecnológicas e paradigmas tecno-econômicos, o qual serviu como modelo para interpretar a atual revolução das tecnologias de informação e comunicação (TIC) e seu conseqüente paradigma tecnoeconômico, e na qual se constatou que este grupo de tecnologias surgiu no período de tempo atual de dito paradigma conhecido como “intervalo de reacomodação” (turning point). Por outro lado, se ressaltou que uma das principais características no processo de difusão de cada paradigma tecno-econômico é o seu impacto na organização das empresas. Desta forma, a teoria evolucionária se apresentou como a abordagem adequada para entender tanto o caráter da empresa atual, entendida esta em termos do conjunto de suas rotinas (conhecimentos e habilidades), quanto as suas principais inovações organizacionais como respostas aos desafios apresentados pela própria difusão do paradigma tecno-econômico atual das TIC, na qual o acumulo permanente de novos conhecimentos e informações, isto é, de rotinas dinâmicas se tornam variáveis chaves para o próprio processo permanente de inovação, vital para as empresas. Diante da crescente utilização das tecnologias de aplicativos da Web 2.0 entre as empresas a nível mundial como meios potenciais para atingir esses objetivos, o presente trabalho analisou o seu potencial para gerar de forma mais fluida novos conhecimentos e informações, isto é rotinas dinâmicas, tanto dentro da organização das empresas como na interação com os seus consumidores, refletindo-se, assim, no aumento de inovações permanentes de novos produtos e serviços. / The main objective of this dissertation is to analyze the technologies of Web 2.0 applications, from an evolutionary perspective, and its impacts on businesses globally. Thus, in order to understand its birth, nature and economic importance for companies, it was taken as theoretical basis the evolutionary concept of technological revolutions and technoeconomic paradigms, which served as a model to interpret the current revolution in information and communication technologies (ICT) and its consequent techno-economic paradigm, in which it was found that this group of technologies originated in the current time of said paradigm known as turning point. On the other hand, it was emphasized that a key feature in the process of diffusion of each techno-economic paradigm is its impact on business organization. Thus, evolutionary theory appeared as the appropriate approach to understand both the character of the current company, which is understood in terms of its set of routines (knowledge and skills), as its main organizational innovations as answers to the challenges presented by the own diffusion of the current ICT techno-economic paradigm, in which the continuous accumulation of new knowledge and information, that is, dynamic routines, become key variables to the self process of continuous innovation, vital for companies. With the increasing use of Web 2.0 application technologies among the companies in the world as a potential means to achieve these goals, this study examined its potential to generate more fluidly new knowledge and information, that is dynamic routines, both within the business organizations and in their interaction with their consumers, which was reflected in the increase of permanent innovations of new products and services.

Caminhos que se bifurcam: idéias, atores, estratégias e interesses na política científica e tecnológica do regime militar / Forking paths: ideas, actors, strategies ans interestsin science and technology policy of the military regime

Ailton Laurentino Caris Fagundes 19 October 2009 (has links)
Este trabalho aborda a política científica e tecnológica brasileira no período do regime militar (1964-1985). As questões às quais ele se refere dizem respeito às idéias e aos interesses de alguns dos seus atores fundamentais: os militares, a comunidade científica e os técnicos responsáveis pela condução da área econômica dos governos. Esses atores, com interesses e idéias distintas e muitas vezes conflituosas acerca dos rumos do desenvolvimento, embora buscassem objetivos diferentes construíram uma trajetória única com projetos ambiciosos para organizar internamente uma rede de instituições que visassem a produção e a aquisição de ciência e tecnologia de ponta. Antes de econômicas, as decisões acerca das políticas de ciência e tecnologia possuíram uma natureza fundamentalmente política e privilegiaram os interesses dos governos e das elites que os sustentaram. Para o Estado, o desenvolvimento científico e tecnológico nem sempre foi um propósito em si; às vezes foi parte de um intento, às vezes um meio para alcançar determinados objetivos. Como meio, essas políticas podiam ser dispensáveis quando se acreditava que era possível ou desejável se chegar aos mesmos resultados percorrendo caminhos mais curtos e menos tortuosos. Seja como meios ou como fins, só é possível entender as políticas do setor quando se tem um horizonte amplo, capaz de deixar perceber quais são os objetivos finais e como eles são perseguidos; para compreender melhor essas relações, dois aspectos são fundamentais: a) as idéias que conduziram à formação, estruturação, organização e atuação do sistema nacional de ciência e tecnologia e dos rumos do desenvolvimento científico e tecnológico no Brasil e, b) os interesses e objetivos que os principais atores possuíam e como esses são, ou não, levados a cabo dentro da estrutura burocrática, e nas ações dos governos, de acordo com as limitações impostas pelos contextos políticos e econômicos internos e externos. / The present thesis approaches the science and technology Brazilian politicses during the period of the military regime (1964-1985). Their main matters tell respect to the ideas and to the interests of some of your central personages: the militaries, the scientific community and the technocrats responsible for the administration of the Government economic sector of that period. Such personages, with interests and distinct thoughts - and many times locking conflicts concerning about of the bearings of the national development, although they sought different goals, they built a single trajectory with ambitious projects to foment internally a joint of institutions with sights to the production and to the acquisition of a science and an advanced technology. Before being economics, the decisions concerning the science and technology policies had a political fundamentally profile and privileged governments\' interests and of the elites that sustained them. For the State, the scientific and technological development not always it was a purpose only; sometimes was a goal, and in at other times was a form of if reach specific goals. Thought as a way, these political can be dispensable from the moment in which it is possible or desirable to reach the same results traversing smaller and less problematic paths. Like means or as ends, only is possible to comprehend the policies of the sector at issue when there is a wide horizon in which is possible to realize whats are the goals and how they are demanded. To comprehend better these relations, two aspects are important: a) the thoughts that led to the formation, structuring and performance of the science and technology national system, as well as of the bearings of the scientific and technological development in Brazil and, b) the interests and objectives that the main personages detained, how were - or were not - carried of radical way inside the bureaucratic structure and in the governments\' lawsuits according to the limitations imposed by the political and economic contexts, both internal and external.

No. of bitstreams: 1 4027.pdf: 1690749 bytes, checksum: 8d859783d2c99e52f4016543ef37c8dd (MD5) Previous issue date: 2011-08-30 / For almost one century, citrus chain has been one of the most important agribusiness for Brazil. Brazil is the largest world orange producer and the largest orange juice exporter, responsible for almost 90% of the worldwide orange juice exportations. Doubtless one of the most important Brazilian sectors, citrus is responsible for a huge percentage of the agribusiness exportations (around USD 1,5bilion/year) and one of the economy motors of the central regions of the State of São Paulo. Over this period, many changes occurred and are still going on into the national and international scenarios. Also, in the XXI century changes have being happened more quick and intense: great fruit and orange juice price oscillations, influence of exchange variation, the 2008 economical crisis, influence of climate conditions and incidence of new diseases, besides demand variations regarding volume and type of product (advent of NFC Not From Concentrate or single strength juice). Citrus processing industry represents a fundamental key role in the whole chain, to achieve new frontiers, putting the Brazilian product into the 5 continents, leveraging exportations to almost 1,300 k/tons of juice exported annually. To guarantee competitiveness in the business, processors have searched continuous improvement on processes, equipment, management techniques as well as quality standards of their products, in order to meet the demands of the market that, year by year, have become more discerning and demanding. There is also the need of continuous improvement and adjustment of the Research & Development techniques for equipment applied to industry, to attend the new parameters. Performance tests of citrus juice equipment are totally important to: evaluate productive process efficiency, investment definition, meet customer s standards and represent a point that impacts the strategic corporate decisions. The purpose of this master s degree dissertation is to propose a method for evaluating the technical-economic stage of citrus juice extraction. The study aims the juice extraction process introduced in the citrus juice extraction chain. For this, it was performed a review of literature and a case study in the segment of citrus juice processing. The research approach used is qualitative and quantitative, using already existent data, from empirical studies conducted in the sector. This work aims to structure and propose a method for the process of citrus juice comparative tests, and the performance evaluation of the extraction system, considering the higher number of variables and ensuring all necessary and sufficient data for decisionmaking. As academic contribution, this work aims to bring an empirical example improvement of food industry equipment, using experimental techniques and data analysis in a specific juice extraction situation, whose results are used for tracking their productive processes, monitoring and improving performance and decision-making regarding changes and investments. / A cadeia citrícola, ao longo de quase um século de existência no Brasil, tem se mostrado uma das mais importantes no agronegócio, visto que o Brasil é o maior produtor mundial de laranjas e o maior exportador de suco cítrico com quase 90% das exportações mundiais. É, sem dúvida, um dos setores mais importantes da economina brasileira, responsável por uma parcela generosa das exportações do agronegócio (cerca de US$ 1,5 bilhões / ano) e um dos motores da economia da região centro do Estado de São Paulo. Ao longo deste período, muitas mudanças ocorreram e continuam acontencendo no cenário nacional e internacional, e no século XXI as mudanças têm se tornado mais rápidas e intensas: grandes oscilações nos preços da fruta e do suco de laranja, influência da variação cambial e da crise econômica de 2008, influência das condições climáticas e incidência de novas doenças, além de variações na demanda no que se refere ao volume e tipo de produto (advento do NFC Not From Concentrate ou suco integral). Nesta cadeia, a indústria de processamento dos cítricos tem papel fundamental no avanço das fronteiras, colocando o produto brasileiro nos cinco continentes, alavancando as exportações com quase um milhão e trezentas mil toneladas de suco exportado anualmente. Para garantir a competitividade no negócio, as indústrias têm buscado melhorias contínuas nos seus processos, equipamentos, técnicas de gestão e também nos padrões de qualidade dos seus produtos, a fim de atender às exigências do mercado consumidor que tem se tornado, a cada ano, mais criterioso e exigente. A fim de atender estes novos parâmetros, há, também, uma necessidade de melhoria contínua e adequação das técnicas de Pesquisa e Desenvolvimento para os equipamentos aplicados na indústria. A realização de testes de desempenho dos equipamentos de extração de sucos cítricos é de fundamental importância na avaliação da eficiência do processo produtivo, definição de investimentos, atendimento aos padrões de qualidade dos clientes, representando um ponto que causa impacto nas decisões estratégicas das empresas. Nesse sentido, esta dissertação de mestrado tem como objetivo a proposição de um método para a avaliação técnica-econômica da etapa de extração de sucos cítricos. O objeto de estudo, inserido na cadeia de produção de sucos cítricos, é o processo de extração de sucos. Para a realização deste trabalho, foi feita uma revisão bibliográfica e um estudo de caso no segmento de processamento de sucos cítricos. A abordagem de pesquisa utilizada é a qualitativa e quantitativa, com a utilização de dados já existentes da literatura e dados de estudos práticos realizados neste setor. Espera-se com este trabalho a estruturação e proposição de um método para o processo de realização de testes comparativos de extração de suco cítrico e a avaliação do desempenho deste sistema de extração, de forma que considere o maior número de variáveis do processo e garanta a obtenção de dados necessários e suficientes para tomadas de decisão. Como uma contribuição acadêmica, espera-se que o trabalho proposto traga um exemplo prático de melhoria no segmento de equipamentos para a indústria de alimentos por meio do uso de técnicas de experimentação e análise de dados em uma situação específica de extração de suco, cujos resultados são utilizados para acompanhamento de seus processos produtivos, monitoramento e aprimoramento de desempenho e tomada de decisão de modificações e investimentos.

Ramalho, Juliana Betarello 28 August 2013 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / The site lithic Cajueiro (BA-RC-19) is located on the banks of the stream in Cajueiro Tree its confluence with the River Correntina, whose area is situated 50 km from the city of Correntina-BA, cerrado in western Bahia. The main purpose of this research is to present a look around the set of lithic material Site Cajueiro (BA-RC-19) in order to understand the cultural choices work with the flint, thus contributing to studies on Prehistory of the Planalto Central. Therefore, we are starting from a technological point of view that you use to discuss the concept of Chaîne-Opératoire, and thus expose the schemes of production and operation of lithic materials analyzed. Understanding the stages of an operational chain having your main goal in mind, the tools, and thus, we believe that for its production several other stigmata of chipping are involved. This process is a mental image of the craftsman who only has meaning within their culture. Our analysis methodologies were able to reconstruct the memory and technical know-how body. So the concept of Chaîne-Opératoire and technofunctional analysis was the chosen path. / O sítio lítico Cajueiro (BA-RC-19) está localizado às margens do córrego Cajueiro em sua confluência com o Rio Correntina, cuja área está situada a 50 km da cidade de Correntina-BA, cerrado do oeste baiano. O principal propósito dessa pesquisa é apresentar um olhar a cerca do conjunto de material lítico do Sítio Cajueiro (BA-RC-19) com a finalidade de entender as escolhas culturais do trabalho com a pedra lascada, contribuindo assim com estudos sobre Pré-História do Planalto Central. Para tanto, estamos partindo de um ponto de vista tecnológico que utiliza para discussão o conceito de cadeia operatória, e assim expor esquemas de produção e perceber potenciais de funcionamento dos materiais líticos analisados. Entendemos as etapas de uma cadeia operatória tendo seu objetivo principal em mente, os instrumentos, e assim, consideramos que para sua produção várias etapas e estigmas de lascamento estão envolvidos. Esse processo é uma imagem mental do artesão que só tem significado dentro de sua cultura. Nossas metodologias de analise foram capazes de reconstituir a memória técnica e o saberfazer corporal. Por isso o conceito de cadeia operatória e a analise tecno-funcional foram o caminho escolhido.

Hagi, Hayato 09 December 2014 (has links)
L’objectif de la thèse est de concevoir un design le plus optimisé possible d’une centrale à charbon pulvérisée fonctionnant en oxy-combustion. Une telle centrale intègre un système de production d’oxygène (ASU), une chaudière, un cycle électrogène, des équipements de dépollution ainsi qu’un système de purification et de compression du CO2 (CPU). Ainsi, dans un premier temps, la thèse portera sur la compréhension, l’analyse et la modélisation des différents procédés qui composent la chaîne d’une centrale fonctionnant en oxy-combustion. Ensuite, les performances et la configuration de la centrale seront optimisées de façon à réduire la destruction d’exergie tout s’assurant de la compétitivité économique de la solution ainsi obtenue. A l’issue de cette thèse, les origines des pertes exergétiques du système étudié et les schémas d’intégration permettant de maximiser les gains énergétique à l’échelle de la centrale seront identifiées. De plus, les stratégies de dépollution des fumées les plus adaptées seront définies et les nouveaux procédés intégrés seront évalués à la fois d’un point de vue technico-économiques et flexibilité. / The objective of the thesis is the conception of an optimized oxy-fired pulverized-coal power plant.

Pengarna som inte kommer fram : Den ekonomiska fördelningsproblematiken i klubbmusik Sverige 2015

Westling, Jonas January 2016 (has links)
Denna uppsats problematiserar hur kollektiva förvaltningsorganisationer fördelar pengar insamlade från offentligt framförd klubbmusik samt undersöker hur etablerade dj’s och producenter ser på dagens system och tror sig påverkas av detta. Med djupintervjuer av fyra personer undersöker uppsatsen även hur dessa ser på rapportering av den spelade musiken, vilka problem som kan uppstå och om det finns tekniska möjligheter att underlätta för korrekt fördelning. Resultaten visar att intervjupersonerna skiljer sig åt i vilken typ av karriär de har och därmed hur man förhåller sig till dagens system. Ingen ställde sig dock positiv till att rapportera in spellistor med vad de spelat som dj’s, man lyfte även fram problemet med att ersätta musik som spelas men ännu inte släppts officiellt. Det framkom också att vi idag har tekniska möjligheter att övervaka vad som spelas genom användandet av akustiska fingeravtryck. Jag diskuterade att det är först när ett sådant system är på plats som vi kan se hur mycket fel dagens pengar fördelas.

Reconfigurable Logic Architectures based on Disruptive Technologies / Architectures logiques reconfigurables utilisant les propriétés de l'électronique moléculaire

Gaillardon, Pierre-Emmanuel 15 September 2011 (has links)
Durant les quatre dernières décennies, l’industrie des semi-conducteurs a connu une croissance exponentielle. En accord avec l’ITRS et à mesure de l'approche vers le nanomètre, les promesses sont énormes et les composants sont réduits à leurs limites physiques et économiques ultimes. L’objectif principal de cette thèse est d’explorer les opportunités offertes par les technologies émergentes pour la conception d’architectures reconfigurables. Tout d’abord, la thèse se centre sur l’architecture FPGA traditionnelle et étudie des améliorations structurelles apportées par des technologies en ruptures. Tandis que les structures de configuration et de routage occupent la majeure partie de la surface d’un FPGA et limitent ces performances, l’intégration 3-D apparait comme une bonne opportunité pour déplacer ces circuits dans les niveaux métalliques. Des circuits de configuration et de routage utilisant des mémoires résistives compatibles back-end, un procédé d’intégration 3-D ou encore un procédé de réalisation de transistors verticaux seront introduits et évalués dans un contexte architectural complet. Par la suite, la thèse présente de nouvelles propositions architecturales pour la logique à grain ultra-fin. La taille des éléments logiques peut être réduite grâce aux propriétés inhérentes de certaines technologies, telles que l’arrangement en structures entrecroisées de nanofils ou la polarité contrôlable des transistors carbones. Considérant le changement de granularité des opérateurs logiques, des topologies d’interconnexions fixes sont nécessaires afin d’éviter l’important surcoût dû à l’interconnexion programmable. Afin d’étudier les possibilités de cette organisation, un flot d’évaluation est présenté et utilisé pour explorer l’espace de conception relatif aux architectures à grain ultra-fin. / For the last four decades, the semiconductor industry has experienced an exponential growth. According to the ITRS, as we advance into the era of nanotechnology, the traditional CMOS electronics is reaching its physical and economical limits. The main objective of this thesis is to explore novel design opportunities for reconfigurable architectures given by the emerging technologies. On the one hand, the thesis will focus on the traditional FPGA architecture scheme, and survey some structural improvements brought by disruptive technologies. While the memories and routing structures occupy the major part of the FPGAs total area and mainly limit the performances, 3-D integration appears as a good candidate to embed all this circuitry into the metal layers. Configuration and routing circuits based on back-end compatible resistive memories, a monolithic 3-D process flow and a prospective vertical FETs process flow are introduced and assessed within a complete architectural context. On the other hand, the thesis will present some novel architectural schemes for ultra-fine grain computing. The size of the logic elements can be reduced thanks to inherent properties of the technologies, such as the crossbar organization or the controllable polarity of carbon electronics. Considering the granularity of the logic elements, specific fixed and incomplete interconnection topologies are required to prevent the large overhead of a configurable interconnection pattern. To evaluate the potentiality of this new architectural scheme, a specific benchmarking flow will be presented in order to explore the ultra-fine grain architectural design space.

Les TICE et l'innovation pédagogique dans l'enseignement supérieur : comment et pourquoi les modes de l’interaction humaine évoluent-ils dans les systèmes d’information pédagogique ? / The ICTE (Information and Communication Technologies for Education) and the Educational Innovation in the Higher Education : Why and How Human Interaction Modes Evolve within the Pedagogical Information Systems ?

Lietart, Armand 10 December 2015 (has links)
Dans le cadre du processus de Bologne et de l’évolution des pratiques traditionnelles vers des modes plus flexibles d’enseignement, notre projet de recherche en cours se propose d’analyser les modalités innovantes d’utilisation des TICE dans les processus d’apprentissage et d’enseignement ainsi que dans les communautés de pratique. Depuis plusieurs années, le concept d’eLearning est entré dans le langage pédagogique et dans les institutions d’enseignement. La plupart des sources consultées le définissent généralement comme un « apprentissage soutenu par les technologies de l’information et de la communication (TIC) » Il s’agit là de définitions intéressantes qui relient l’apprentissage (considéré comme objectif de l’action) avec les technologies (considérées le plus souvent comme un moyen). Cette proximité dans la définition ne signifie pas causalité. Jusqu’ici, toutes les recherches sur les différentes formes de technologies qui sont apparues dans les trente dernières années (de l’EAO au Cédérom interactif), ont conclu en l’importance du dispositif pédagogique dans lequel les outils technologiques sont immergés (Kadiyala & Crynes, 2000). Ceci peut expliquer une grande partie des recherches actuelles sur les conditions d’efficacité des technologies de l’information et de la communication (Technology Enhanced Learning) dans l’éducation (Quelles méthodes ? Quels dispositifs ?) et la recherche des valeurs ajoutées (Quels résultats ?). D’autres recherches ont vu dans les technologies un catalyseur et un accélérateur de l’innovation pédagogique dans les institutions (Liétart, 2007). Dans ce sens, le contexte des Universités de la Communauté française de Belgique (et/ou européennes) est particulièrement intéressant à investiguer : le mélange actuel de formes d’enseignements très variées, les usages technologiques principalement autour de certaines plates-formes comme Claroline (pour bon nombre de partenaires potentiels), la présence de disciplines d’enseignement contrastées, les formes tout aussi variées de formation des enseignants, d’encouragement aux innovations pédagogiques, les dispositifs hybrides, … constituent à la fois un terrain riche et des variables intéressantes à investiguer pour une meilleure compréhension des conditions et des facteurs de qualité de l’innovation technopédagogique et de l’interaction homme/ machine. / The ICTE (Information and Communication Technologies for Education) and the Educational Innovation in the Higher Education : Why and How Human Interaction Modes Evolve within the Pedagogical Information Systems ? ”Within the framework of the Bologna process and the evolution of the traditional practices towards more flexible ways of teaching, our ongoing research project, proposes to analyse the innovative modes of the use of the ICTE in the educational and learning process just as in the practice communities. For many years, the eLearning concept came in the common educational usage and in the educational institutions. Most of the sources we refered to, generally define it as a “learning supported by the ICT”. These are interesting definitions that link the learning process (considered as the action’s goal) with the technologies (considered most of the time as a means). This closeness in the definition doesn’t mean causality. Until now, all the research on the different forms of technologies that appeared during the last thirty years (from the Teaching Assisted by Computer TAC to interactive cd) have highlighted the importance of the educational system in which technological tools are immersed (Kadiyala & Crynes, 2000). This can explain for a large part of the current researches on the conditions of the efficiency of the information and the communication technologies, (Technology Enhanced Learning) in education (Which methods? Which systems?), and the research of the added values (Which results?). Other researches consider the technologies as a catalyst and an accelerator of the pedagogic innovation in the institutions (Liétart, 2007). In that matter, the context of the Universities of the French Community of Belgium (and/or European) is particularly interesting to investigate : the much diversified current mix of educational forms, the technological uses mainly around certain platforms such as Claroline (for many potential partners), the presence of contrasting educational disciplines, the also diversified teacher’s training, the encouragement for educational innovations, the hybrid devices …constitute at the same time a rich field and interesting variables to investigate for a better comprehension of the conditions and of the quality factors of techno-educational innovation and of the human/machine interaction.
