Esta tese, que se insere na área de História e Historiografia da Educação, busca compreender os processos de construção do tempo das escolas primárias em São Paulo, entre os anos de 1846 e 1890, num momento em que os sistemas públicos primários de ensino emergiam no âmbito mundial. Particularmente, procura-se entender como as discussões que antecedem a criação das escolas graduadas (1893), corroboram o delineamento de um tempo próprio da escola. As fontes da legislação, dos relatórios de inspeção e dos professores além de outras fontes manuscritas como mapas de freqüência, livros de matrícula, circulares, ofícios, encontrados no Arquivo do Estado trazem elementos significativos acerca do que se entendia quanto a tempo escolar, quais as categorias que se faziam presentes, os desafios da construção de um tempo próprio da escola num momento em que a escola primária ainda não era considerada como responsável ou legítima para educar as crianças. Os conceitos de estratégias (Certeau), representações e apropriações (Chartier) sustentam o exame das fontes. Este trabalho evidencia a transição de um tempo da infância regulado por outras referências sociais para um tempo regulado também pela escola. Embora comporte diversas possibilidades analíticas, a expressão \"estudo sobre o tempo das escolas públicas primárias\" designa o conjunto de medidas e discussões tanto administrativo-organizacionais referentes ao calendário (dias letivos ou não, interrupções das aulas, feriados, férias, matrícula, exames); aos marcos como a idade e os horários e a quantidade de horas de permanência na escola; e à organização do tempo didático (Chevallard e Mercier). O que se chama de tempo didático integra a duração do ensino primário, a definição e ordenação dos conteúdos a serem desenvolvidos com as crianças, os modos de ensinar e aprender e o emprego do tempo. É visível, a partir de meados do século XIX, que cada um desses elementos da estrutura temporal da escola vai sendo arquitetado para integrar pouco a pouco uma temporalidade identitária da instituição escolar. Nesse processo, instalaram-se novos tempos para os professores, para os alunos, mas também para a sociedade em geral, e, de modo particular, para as famílias que tinham crianças nas escolas primárias. Ao situar-se num momento histórico que antecede o que há alguns anos foi consagrado pela literatura tradicional de História da Educação como o \"período áureo da educação brasileira\", de modo particular os anos 1890 e 1920, este estudo colabora com as discussões já iniciadas sobre a construção das escolas públicas primárias em São Paulo, mediante a ênfase no aspecto temporal. / This thesis, in the field of Education History and Historiography, aims to understand the processes by which time was constructed in elementary schools in São Paulo, between the years of 1846 and 1890. That was a period when public elementary systems of schooling arose in a worldwide set. It is of special interest to understand how the debates that occurred before the creation of graduated schools (1893), contributed to the definition of school times. This analysis has to consider the specific context of the society (slavery, monarchy, rural economy), its institutions dedicated to the education of childhood (as family and Church) and the school existent in the period. Through this analysis it is possible to contibute to the understanding of the specificities of school culture, considering that it is builted from a specific context in the intersection of social ends (Julia). This concept is also apprehended as the combination of influences from the norms, from those who act in teaching and scholar theories (Escolano). Considering that the school culture and form of the graduate school come from earlier periods (Julia, Vincent) we integrate to this text histories of time in other countries and the cultural influences of other periods and institutions. The documentary sources are the legislation, inspectors\' and teachers\' reports, as well as other manuscripts as freqüency maps, enrollment books and deliberations on everyday business found in the State Archive. These documents express strategies (Certeau), representations and appropriations (Chartier) and bring significant elements on what was understood as school time, what were the categories used and the challenges of the construction of a specific school time when the elementary school wasn\'t still perceived as the main and legitimate institution for the education of the children. In this sense, this research shows the transition of an infant time ruled by other social references to a time that is also regulated by the school. The generic expression \"study on the time of public elementary schools\" contemplates several analytical possibilities, however it refers here to a set of administrative and legal measures, as well as the debates. This set concerns the calendar (school days, hollydays, vacations, enrollment, tests); the milestones as proper school age as well as the distribution and total amount of hours students had to remain in school; also the organization of the didactic time (Chevallard e Mercier) that is a part of elementary schooling, the definition and organization of the contents to be taught to the children, ways of teaching and learning - all of that concerning to the employment of time. It is noticeable, since the middle of the XIXth. Century, that each and every one of these elements of school temporal structure was being planned to integrate progressively a temporality that is central to the identity of this institution. During this process, new times were imposed on teachers and students, but also on the general society and particularly on the families that had children in elementary schools. This analysis contributes to the debates on the construction of public elementary schools in São Paulo because it points out processes that emerged before the period that is traditionally considered by the History of Education as the \"golden ages\" of schooling in the country (especially the years of 1890 and 1920).

Este trabalho apresenta a concepção, o projeto, o desenvolvimento e a validação experimental de uma plataforma robótica bioinspirada o robô KA\'I yxo com a habilidade de escalar árvores para aplicação em monitoramento ambiental. Tal motivação surgiu da necessidade crescente do estudo e do entendimento de ocorrências naturais pelas consequências envolvidas, muitas vezes trágicas. O monitoramento ambiental em larga escala e a dificuldade de acesso e cobertura de áreas significativas são fatores que indicam a importância e a utilidade de robôs nessas tarefas. O robô KA\'I yxo possui como aplicação primeira uma solução para aquisição de dados de radiação solar, temperatura, umidade e altitude, de maneira que a mesma seja uma ferramenta útil para pesquisadores, aplicação esta identificada como relevante para a pesquisa na área ambiental após visitas ao Instituto Nacional de Pesquisas da Amazônia INPA. O desenvolvimento da plataforma robótica bioinspirada exposto nesta tese apresenta a sua evolução, desde a versão inicial do robô Kamanbaré (seis versões), até a versão atual da plataforma KAI yxo (terceira versão). Para esta última, são expostos em detalhes os modelos mecânico e matemático. No modelo mecânico, a importante questão da mobilidade é considerada. O modelo matemático construído compreende a cinemática direta, a cinemática inversa, a definição da andadura e a dinâmica do robô. O texto contém também uma apresentação detalhada das arquiteturas de controle, de software e de hardware. A utilização de Geradores Centrais de Padrões (CPGs) é justificada e discutida em detalhes. O ajuste dos parâmetros da CPG é realizado por meio de um processo de otimização baseado na técnica de Times Assíncronos (A-Teams). Resultados experimentais obtidos com a plataforma robótica são apresentados e discutidos. / This work presents the conception, design, development and experimental validation of a bioinspired robotics platform the robot KA\'I yxo with the ability to climb trees for use in environmental monitoring. Such motivation arose from the growing need of studying and understanding the consequences of natural occurrences involved, often tragic. Environmental monitoring in large scale and the difficulty of access and coverage areas are significant factors that indicate the importance and the usefulness of robots in these tasks. As a first application, the robot KA\'I yxo represents a solution for data acquisition from solar radiation, temperature, humidity and altitude, so that it may be a useful tool for researchers. This application was identified as relevant to environmental research after visits to the National Institute of Amazonian Research INPA. The development of the bio-inspired robotics platform exposed in this thesis presents its evolution starting from the initial version of the robot Kamanbaré (six versions) and ending with the current version of KA\'I yxo platform (third version). For the latter, the mechanical and mathematical models are exposed in details. In the mechanical model, the important issue of mobility is considered. The mathematical model constructed comprises the forward kinematics, the inverse kinematics, the definition of the gait and the dynamics of the robot. The text also contains a detailed presentation of the control, software and hardware architectures. The use of Central Pattern Generators (CPGs) is justified and discussed. The tuning of the CPG parameters is performed by an optimization process based on the Asynchronous Teams (ATeams) technique. Experimental results obtained with the robotic platform are presented and discussed.

In der Erforschung der Städtebaukunst stehen die bildenden Künste im Vordergrund. Die Frage nach den technischen Künsten wird kaum gestellt, obwohl der Entwurf des Architekten nicht nur von individueller Intuition, sondern im gleichen Maße auch vom technisch Machbaren geprägt ist. Um aber das der Planung frühneuzeitlicher Städte zugrunde liegende Konstruktionsschema und die Planungsintention erkennen zu können, ist es notwendig die Städtebau- mit der Technikgeschichte zu verbinden. Die in den Tratakten zur geometria practica und zur architectura militaris beschriebenen Konstruktions- und Vermessungsmethoden werden städtebaulichen Planungen der Frühen Neuzeit gegenübergestellt. An einzelnen Fallstudien, die vom Ende der mittelalterlichen Stadtplanung bis hin zu barocken Stadterweiterungen reichen, wird untersucht, wie das Planungswerkzeug die Entwurfssprache des Architekten beeinflusste und die Formensprache der Stadt- und Landschaftsplanung nachhaltig veränderte. Der Paradigmenwechsel im Städtebau vollzog sich in Mitteleuropa um die Wende vom 15. zum 16. Jh. mit dem Bau der Erzgebirgsstädte Annaberg und Marienberg. Die in Annaberg noch praktizierte rhythmische und räumliche Grundrissgestaltung wurde in Marienberg zugunsten eines egalisierten Stadtgrundrisses aufgegeben. Überlegungen zur Stadtstruktur und Hygiene führten zu diesem Wandel, die Aufteilung des Grundrisses selber aber wurde durch das verwendete Instrumentarium bestimmt. Im Barock stand den Planern Geometrie als allgemeine Kulturtechnik zur Verfügung, das Denken in geometrischen Formen und Proportionen bestimmte den Entwurfsprozess. Geometrie war nicht mehr nur Planungsmittel, sondern wurde - wie bei der Anlage der Berliner Torplätze zu Beginn des 18. Jh. zu sehen ist - Planungsziel. Die Rekonstruktion der Planungsmaße beweist, dass nicht nur die Namensgebung - Rondell, Oktogon und Quarré – auf die Quadratur des Kreises hinweist, sondern die Proportion der Plätze aus ihr heraus entwickelt wurde. / In the research of the art of urban development, the fine arts are mainly taken into account. The question of the technical arts is seldom raised, even though the architect’s design is a work of personal intuition as well as of the technically possible. In order to recognize the construction scheme and the planning intention in the urban planning of Early Modern Times it is necessary to merge the history of urban development with the history of technology. The construction and surveying methods described in the essays of the geometria practica and the architectura militaris are compared to the urban planning of the Early Modern Times. In case studies reaching from urban planning at the close of the Middle Ages to Baroque city expansion it is shown how the planning tools influenced the design language of the architect and the form language of urban development. The paradigm shift in Middle European urban planning took place at the end of the 15th century with the construction of Annaberg and Marienberg in the Ore Mountains. The rhythmic and spatial floor plan design still used in Annaberg was abandoned for a leveled out town plan in Marienberg. Deliberations of city structure and hygiene lead to this change. The design of the layout itself, however, was dictated by the implemented tool. In the Baroque period, geometry was available to the planers as general cultural knowledge and technology: the use of geometrical forms and proportions determined the design process. Geometry was not only planning method, but became planning intention – as can be seen by the Berlin Gate Plazas built in the beginning of the 18th Century. Not only do the names given - Rondell, Oktogon and Quarré – refer to the squaring of the circle, but the reconstruction of the design measurements proves the connection. Only the development of practical geometry enabled the variable form language of Baroque city construction.

Diese Dissertation besteht aus drei unabhängigen Kapiteln in den Bereichen Matching Market Design, Industrieökonomie und Wettbewerbspolitik. Kapitel 1 behandelt den Matching-Markt für juristische Referendariatsstellen in Deutschland. Wegen übermäßiger Nachfrage müssen Anwälte oft warten, bevor sie zugewiesen werden. Der aktuell verwendete Algorithmus berücksichtigt nicht die Zeitpräferenzen der Anwälte. Daher werden viele wünschenswerte Eigenschaften nicht erfüllt. Basierend auf dem matching with contracts Modell schlage ich dann einen neuen Mechanismus vor, der die Wartezeit als Vertragsterm verwendet, so dass die Mängel des gegenwärtigen Mechanismus überwunden werden können. In Kapitel 2 analysiere ich den Wettbewerb von zweiseitigen Online-Plattformen, wie sozialen Netzwerken oder Suchmaschinen. Werbetreibende zahlen Geld, um ihre Anzeigen zu platzieren, während Nutzer mit ihren privaten Daten "bezahlen", um Zugang zu der Plattform zu erhalten. Ich zeige, dass das Gleichgewichtsniveau der Datenerhebung verzerrt ist, abhängig von der Intensität des Wettbewerbs und den Targeting-Vorteilen. Weniger Wettbewerb auf jeder Marktseite führt zu mehr Datensammeln. Wenn jedoch Plattformen Geldzahlungen auf beiden Marktseiten verwenden, wird die effiziente Menge an Daten gesammelt. Kapitel 3 untersucht die dynamische Preissetzung auf Märkten für Flug- oder Reisebuchungen, auf denen Wettbewerb während einer endlichen Verkaufszeit mit einer Frist stattfindet. Unter Berücksichtigung der intertemporalen Probleme von Firmen und vorausschauenden Konsumenten hängen die Gleichgewichtspreispfade von der Anzahl der nicht verkauften Kapazitäten und der verbleibenden Verkaufszeit ab. Ich ermittle, dass mehr Voraussicht der Konsumenten die Konsumentenrente erhöht, aber die Effizienz reduziert. Ferner ist Wettbewerbspolitik besonders wertvoll, wenn die Marktkapazitäten zu hoch sind. Des Weiteren kann die ex-ante Produktion von Kapazitäten ineffizient niedrig sein. / This thesis consists of three independent chapters in the fields of matching market design, industrial organization and competition policy. Chapter 1 covers the matching market for lawyer trainee-ship positions in Germany. Because of excess demand lawyers often must wait before being allocated. The currently used algorithm does not take lawyers’ time-preferences into account. Hence, many desirable properties are not satisfied. Then, based on the matching with contacts model, I propose a new mechanism using waiting time as the contractual term, so that the shortcomings of the current mechanism can be overcome. In Chapter 2 I analyze competition of two-sided online platforms, such as social networks or search engines. Advertisers pay money to place their ads, while users “pay” with their private data to gain access to the platform. I show that the equilibrium level of data collection is distorted, depending on the competition intensity and targeting benefits. Less competition on either market side leads to more data collection. However, if platforms use monetary payments on both market sides, data collection would be efficient. Chapter 3 studies dynamic pricing as in markets for airline or travel bookings, where competition takes place throughout a finite selling time with a deadline. Considering the inter-temporal problems of firms and forward-looking consumers, the equilibrium price paths depend on the number of unsold capacities and remaining selling time. I find that more consumer foresight increases consumer surplus yet reduces efficiency. Further, competition policy is especially valuable when market capacities are excessive. Moreover, ex-ante capacity production can be inefficiently low.

Die vorliegende Dissertation beschäftigt sich mit der Anwendung der Theorie der großen Abweichungen auf verschiedene Fragestellungen der stochastischen Analysis und stochastischen Dynamik von Sprungprozessen. Die erste Fragestellung behandelt die erste Austrittszeit aus einem beschränkten Gebiet für eine bestimmte Klasse von Sprungdiffusionen mit exponentiell leichten Sprüngen. In Abhängigkeit von der Leichtheit des Sprungmaßes wird das asymptotische Verhalten der Verteilung und insbesondere der Erwartung der ersten Austrittszeit bestimmt wenn das Rauschen verschwindet. Dabei folgt die Verteilung der ersten Austrittszeit einem Prinzip der großen Abweichungen im Falle eines superexponentiellen Sprungmaßes. Wohingegen im subexponentiellen Fall die Verteilung einem Prinzip moderater Abweichungen genügt. In beiden Fällen wird die Asymptotik bestimmt durch eine deterministische Größe, die den minimalen Energieaufwand beschreibt, um die Sprungdiffusion einen optimalen Kontrollpfad, der zum Austritt führt, folgen zu lassen. Die zweite Fragestellung widmet sich dem Grenzverhalten gekoppelter Vorwärts-Rückwärtssysteme stochastischer Differentialgleichungen bei kleinem Rauschen. Dazu assoziiert ist eine spezielle Klasse nicht-lokaler partieller Differentialgleichungen, die auch in nicht-lokalen Modellen der Fluiddynamik eine Rolle spielen. Mithilfe eines probabilistischen Ansatzes und der Markovschen Struktur dieser Systeme wird die Konvergenz auf Ebene von Viskositätslösungen untersucht. Dabei wird ein Prinzip der großen Abweichungen für die involvierten Stochastischen Prozesse hergeleitet. / This thesis deals with applications of Large Deviations Theory to different problems of Stochastic Dynamics and Stochastic Analysis concerning Jump Processes. The first problem we address is the first exit time from a fixed bounded domain for a certain class of exponentially light jump diffusions. According to the lightness of the jump measure of the driving process, we derive, when the source of the noise vanishes, the asymptotic behavior of the law and of the expected value of first exit time. In the super-exponential regime the law of the first exit time follows a large deviations scale and in the sub-exponential regime it follows a moderate deviations one. In both regimes the first exit time is comprehended, in the small noise limit, in terms of a deterministic quantity that encodes the minimal energy the jump diffusion needs to spend in order to follow an optimal controlled path that leads to the exit. The second problem that we analyze is the small noise limit of a certain class of coupled forward-backward systems of Stochastic Differential Equations. Associated to these stochastic objects are some nonlinear nonlocal Partial Differential Equations that arise as nonlocal toy-models of Fluid Dynamics. Using a probabilistic approach and the Markov nature of these systems we study the convergence at the level of viscosity solutions and we derive a large deviations principles for the laws of the stochastic processes that are involved.

Diese Dissertation präsentiert neue Techniken der Integration für verschiedene Probleme der Finanzmathematik und einige Anwendungen in der Wahrscheinlichkeitstheorie. Zu Beginn entwickeln wir zwei Zugänge zur robusten stochastischen Integration. Der erste, ähnlich der Ito’schen Integration, basiert auf einer Topologie, erzeugt durch ein äußeres Maß, gegeben durch einen minimalen Superreplikationspreis. Der zweite gründet auf der Integrationtheorie für rauhe Pfade. Wir zeigen, dass das entsprechende Integral als Grenzwert von nicht antizipierenden Riemannsummen existiert und dass sich jedem "typischen Preispfad" ein rauher Pfad im Ito’schen Sinne zuordnen lässt. Für eindimensionale "typische Preispfade" wird sogar gezeigt, dass sie Hölder-stetige Lokalzeiten besitzen. Zudem erhalten wir Verallgemeinerungen von Föllmer’s pfadweiser Ito-Formel. Die Integrationstheorie für rauhe Pfade kann mit dem Konzept der kontrollierten Pfade und einer Topologie, welche die Information der Levy-Fläche enthält, entwickelt werden. Deshalb untersuchen wir hinreichende Bedingungen an die Kontrollstruktur für die Existenz der Levy-Fläche. Dies führt uns zur Untersuchung von Föllmer’s Ito-Formel aus der Sicht kontrollierter Pfade. Para-kontrollierte Distributionen, kürzlich von Gubinelli, Imkeller und Perkowski eingeführt, erweitern die Theorie rauher Pfade auf den Bereich von mehr-dimensionale Parameter. Wir verallgemeinern diesen Ansatz von Hölder’schen auf Besov-Räume, um rauhe Differentialgleichungen zu lösen, und wenden die Ergebnisse auf stochastische Differentialgleichungen an. Zum Schluß betrachten wir stark gekoppelte Systeme von stochastischen Vorwärts-Rückwärts-Differentialgleichungen (FBSDEs) und erweitern die Theorie der Existenz, Eindeutigkeit und Regularität der sogenannten Entkopplungsfelder auf Markovsche FBSDEs mit lokal Lipschitz-stetigen Koeffizienten. Als Anwendung wird das Skorokhodsche Einbettungsproblem für Gaußsche Prozesse mit nichtlinearem Drift gelöst. / In this thesis new robust integration techniques, which are suitable for various problems from stochastic analysis and mathematical finance, as well as some applications are presented. We begin with two different approaches to stochastic integration in robust financial mathematics. The first one is inspired by Ito’s integration and based on a certain topology induced by an outer measure corresponding to a minimal superhedging price. The second approach relies on the controlled rough path integral. We prove that this integral is the limit of non-anticipating Riemann sums and that every "typical price path" has an associated Ito rough path. For one-dimensional "typical price paths" it is further shown that they possess Hölder continuous local times. Additionally, we provide various generalizations of Föllmer’s pathwise Ito formula. Recalling that rough path theory can be developed using the concept of controlled paths and with a topology including the information of Levy’s area, sufficient conditions for the pathwise existence of Levy’s area are provided in terms of being controlled. This leads us to study Föllmer’s pathwise Ito formulas from the perspective of controlled paths. A multi-parameter extension to rough path theory is the paracontrolled distribution approach, recently introduced by Gubinelli, Imkeller and Perkowski. We generalize their approach from Hölder spaces to Besov spaces to solve rough differential equations. As an application we deal with stochastic differential equations driven by random functions. Finally, considering strongly coupled systems of forward and backward stochastic differential equations (FBSDEs), we extend the existence, uniqueness and regularity theory of so-called decoupling fields to Markovian FBSDEs with locally Lipschitz continuous coefficients. These results allow to solve the Skorokhod embedding problem for a class of Gaussian processes with non-linear drift.

There are always different ways of saying the same thing, and these modes are not accidental alternatives. Differences in expression bring ideological distinctions, and thus differences of representation. In the decade of 2008, the world went through an economic recession triggered by US mortgage lending, which led to bank failures, unemployment and rising poverty. Lehman Brothers’ bankruptcy is considered one of the most important milestones of the 21st century, equated only with the terrorist attacks of September 11. The analysis will be made in editorials of two newspapers: Folha de S.Paulo and The New York Times, with basic support of the Systemic-Functional Grammar (SFG). The SFG’s theoretical-methodological proposal makes it possible to relate the lexicographic choices of the text microstructure to the macro structure of ideology and force relations, establishing a link between social and individual, macro and micro, social and cognitive typology. This type of approach is especially useful in examining the discourse of different groups with specific ideological characteristics. For SFG, language has the function of constructing three meanings – or metafunctions: ideational (information), interpersonal (interaction) and textual (linguistic organization of metafunctions). SFG also involves Critical Linguistics, to which any aspect of the linguistic structure carries ideological significance – lexical selection, syntactic choice, etc. The research should answer the following questions: (a) How can ideational metafunction, through transitivity, construct the representation concerning Lehman Brothers bankruptcy? (b) What role do interpersonal metafunctions have, through modality and evaluativeness, in this process? The results show that the Brazilian editorial “Cada vez pior” describes and narrates the negative aspects of the crisis, however, without positioning against or in favor of the issue, while the American editorial “Wall Street Casualties” also describes and narrates, but suggests positive aspects of the collapse / O objetivo desta dissertação é a análise crítica da representação feita pela mídia com referência à falência do Lehman Brothers, uma das maiores instituições bancárias do mundo, bem como aos atores envolvidos. Há sempre modos diferentes de dizer a mesma coisa, e esses modos não são alternativas acidentais. Diferenças em expressão trazem distinções ideológicas, e assim diferenças de representação. Na década de 2008, o mundo passou por uma recessão econômica desencadeada pelos empréstimos hipotecários americanos, que acarretaram falências bancárias, desemprego e aumento da pobreza. A falência do Lehman Brothers é considerada como um dos marcos mais importantes do século XXI, igualado somente aos ataques terroristas de 11 de setembro. A análise será feita em editoriais de dois jornais: a Folha de S.Paulo e o The New York Times, com apoio básico da Gramática Sistêmico-Funcional (GSF). A proposta teórico-metodológica da GSF possibilita relacionar as escolhas léxicogramaticais da microestrutura do texto com a estrutura macro da ideologia e das relações de força, estabelecendo um elo entre o social e o individual, o macro e o micro, o social e o cognitivo. Esse tipo de abordagem é especialmente útil no exame do discurso de diferentes grupos com características ideológicas específicas. Para a GSF, a língua tem a função de construir três significados – ou metafunções: ideacional (informação), interpessoal (interação) e textual (organização linguísticas das referidas metafunções). A GSF envolve também a Linguística Crítica, para a qual qualquer aspecto da estrutura linguística carrega significação ideológica – seleção lexical, opção sintática, etc. A pesquisa deve responder às seguintes perguntas: (a) Como a metafunção ideacional, por meio da transitividade, pode construir a representação referente à falência do Lehman Brothers? (b) Que papel têm a metafunção interpessoal, por meio da modalidade e da avaliatividade nesse processo? Os resultados mostram que o editorial brasileiro “Cada vez pior” descreve e narra os aspectos negativos da crise, embora sem se posicionar contra ou a favor da questão, ao passo que editorial americano “Wall Street Casualties”, ao descrever e narrar, sugere aspectos positivos da derrocada

L’histoire de l’olivier et de l’huile d’olive est indissociable de l’histoire de l’agriculture corse. La réalité historique de la culture de l’olivier et de la production d’huile a été appréhendée à partir de la fin du XVIe siècle jusqu’à la veille de la première guerre mondiale. Le paysage oléicole a connu un grand développement à l’époque moderne sous l’impulsion de la Sérénissime République de Gênes ; il s’est poursuivi au XIXe siècle sous l’autorité de l’administration française. L’étude de l’ensemble des microrégions de l‘île a mis en évidence le rôle majeur joué par les communautés dans l’économie oléicole insulaire. On parle d’une diversité et non d’une unicité de l’olivier en Corse : diversité des variétés, des pratiques culturales, des modes d’extraction de l’huile, des paysages… L’impact économique de cette culture durant la période étudiée a été très important pour la Corse. L’olivier est au cœur des préoccupations des hommes, il a transformé partiellement l’agriculture, les paysages, les infrastructures de transports, l’architecture rurale et a participé à l’émergence d’une société microrégionale originale. / The olive tree and olive oil's history is inseparable from the History of the Corsican agriculture. The real nature of the culture of the olive tree and the production of the olive oil have been comprehended from the end of the XVIth century to the eve of the first world war. The olive landscape knew a great development during the modern age with the Serene highness Republic of Genoa; it pursuded on the XIXth century under the authority of the French administration. The study on the whole microregions of the island higlights the main part played by the comunities in the oleicol economy of the island. Concerning the olive tree in Corsica we notice an important diversity of trees not an uniquiness: diversity of the sorts of trees, of the cultural pratices, of ways to extract the oil, of landscapes... the economic impact of this culture during the era studied had been really important for Corsica. The olive tree is at the heart of the humans' concerns, it partially transformed the agriculture, the landscapes and the substructure of the transports, the rural architecture and took part in the emergence of an original regional micro society. / A storia di l'alivu è di l'oliu d'aliva hè propiu ligata à a storia di l'agricultura corsa.

Em grande parte, isso ocorre pelo fato de os componentes de um time virtual global terem impactos com a tecnologia de comunicação (não é face to face) e muita interação eletrônica como meio de integração. Aliado a isso, existem barreiras no processo de trabalho, como diferenças culturais, fuso horário e idioma, que aumentam muito os desafios em relação às equipes presenciais. A presente dissertação buscou investigar e analisar os fatores-chave na gestão de um time virtual global sob o prisma de uma multinacional de um país em desenvolvimento. O método utilizado foi o estudo de caso único, por se tratar de um caso contemporâneo e pela acessibilidade dos dados, quando o pesquisador tem acesso limitado a outras fontes (GIL, 2002). Para análise de dados, foi utilizada a triangulação das informações e a técnica de conteúdo. Os resultados evidenciam fatores-chave para boa gestão dos times virtuais, corroborando com outras pesquisas sobre o tema. No entanto, este estudo permitiu observar peculiaridades, como fatores específicos em um país em desenvolvimento que não foram verificados na literatura. / Global virtual teams have specific characteristics in relation to face-to-face teams and the work dynamics and interpersonal relationships are more complex in a virtual team, and it is necessary to manage differently. This is largely due to the fact that the global virtual team components have communication technology impacts (not face to face) and a lot of electronic interaction as integration possibility. In addition, there are barriers in the work process such as: cultural differences; time zone; language, which considerably increases the challenges in relation to face-to-face teams. The present dissertation looked for to investigate and analyze the key factors in a global virtual team management under the multinational in a developing country focus. The method used was the single case study, because it was contemporary with limited data accessibility, when the researcher has limited access to other sources (GIL, 2002). For data analysis was used the triangulation data and content technique. The result shows key factors for virtual team’s good management, corroborating with other research on this subject. However, this study allowed us to observe peculiarities such as specific factors in a developing country multinational that were not verified in the literature.
