Esta pesquisa tem como objetivo principal analisar a apropriação do desenvolvimento geográfico desigual brasileiro pelas empresas de Contact Center. A constituição e expansão das operações brasileiras de teleatendimento estão atreladas às privatizações do setor de telecomunicações, com a aquisição das empresas estatais por grandes transnacionais, e a consequente terceirização dos serviços a partir do final da década de 1990. A análise da divisão territorial do trabalho das operações de teleatendimento revela a presença de forças centrípetas, com a manutenção do controle nas principais metrópoles brasileiras, e centrífugas, com a dispersão das unidades de produção para os centros urbanos não metropolitanos e para a região Nordeste. O uso seletivo da densidade técnica e informacional do território permite às empresas a incorporação lucrativa de áreas onde os recursos, principalmente, capital e trabalho, são desvalorizados. / The present work intends to analyze the exploitation of Brazilian uneven geographical development by Contact Center companies. Since the end of the 1990s, the establishment and expansion of Brazilian operations telemarketing has been linked to the privatization of the telecommunications sector, with the subsequent acquisition of state enterprises by large transnational corporations, with has resulted in the outsourcing of services. The corporations territorial division of labor shows the presence of both centripetal forces, with maintenance control in major Brazilian cities, and centrifugal forces, with the dispersion of production facilities in non-­ metropolitan and urban centers in the Northeast. The selective use of technical and informational density allows companies to lucratively incorporate areas where resources, especially labor and capital, are devalued.

La programmation par contraintes est une approche régulièrement utilisée pour résoudre des problèmes combinatoires d’origines diverses. Dans cette thèse nous nous focalisons sur les problèmes d’ordonnancement cumulatif. Un problème d’ordonnancement consiste à déterminer les dates de débuts et de fins d’un ensemble de tâches, tout en respectant certaines contraintes de capacité et de précédence. Les contraintes de capacité concernent aussi bien des contraintes cumulatives classiques où l’on restreint la somme des hauteurs des tâches intersectant un instant donné, que des contraintes cumulatives colorées où l’on restreint le nombre maximum de couleurs distinctes prises par les tâches. Un des objectifs récemment identifiés pour la programmation par contraintes est de traiter des problèmes de grandes tailles, habituellement résolus à l’aide d’algorithmes dédiés et de métaheuristiques. Par exemple, l’utilisation croissante de centres de données virtualisés laisse apparaitre des problèmes d’ordonnancement et de placement multi-dimensionnels de plusieurs milliers de tâches. Pour atteindre cet objectif, nous utilisons l’idée de balayage synchronisé considérant simultanément une conjonction de contraintes cumulative et des précédences, ce qui nous permet d’accélérer la convergence au point fixe. De plus, de ces algorithmes de filtrage nous dérivons des procédures gloutonnes qui peuvent être appelées à chaque nœud de l’arbre de recherche pour tenter de trouver plus rapidement une solution au problème. Cette approche permet de traiter des problèmes impliquant plus d’un million de tâches et 64 ressources cumulatives. Ces algorithmes ont été implémentés dans les solveurs de contraintes Choco et SICStus, et évalués sur divers problèmes déplacement et d’ordonnancement. / Constraint programming is an approach often used to solve combinatorial problems in different application areas. In this thesis we focus on the cumulative scheduling problems. A scheduling problem is to determine the starting dates of a set of tasks while respecting capacity and precedence constraints. Capacity constraints affect both conventional cumulative constraints where the sum of the heights of tasks intersecting a given time point is limited, and colored cumulative constraints where the number of distinct colors assigned to the tasks intersecting a given time point is limited. A newly identified challenge for constraint programming is to deal with large problems, usually solved by dedicated algorithms and metaheuristics. For example, the increasing use of virtualized datacenters leads to multi dimensional placement problems of thousand of jobs. Scalability is achieved by using a synchronized sweep algorithm over the different cumulative and precedence constraints that allows to speed up convergence to the fix point. In addition, from these filtering algorithms we derive greedy procedures that can be called at each node of the search tree to find a solution more quickly. This approach allows to deal with scheduling problems involving more than one million jobs and 64 cumulative resources. These algorithms have been implemented within Choco and SICStussolvers and evaluated on a variety of placement and scheduling problems.

With known techniques their textural properties were determined and dynamics techniques in programmed temperature were used to find the acid properties of the materials. A thermodynamic model was used to determine the adsorption and desorption capacity of chloromethane. Two types of reactions were studied. Firstly the chloromethane was catalytically converted to hydrocarbons (T = 300 450 oC e m = 300 mg) in a fixed bed reactor with controlled pressure and flow. Secondly the deactivation of the unmodified support was studied (at 300 ?C and m=250 g) in a micro-adsorver provided of gravimetric monitoring. The metal content (2,5%) and the chloromethane percent of the reagent mixture (10% chloromethane in nitrogen) were fixed for all the tests. From the results the chloromethane conversion and selectivity of the gaseous products (H2, CH4, C3 and C4) were determined as well as the energy of desorption (75,2 KJ/mol for Ni/Al2O3-SiO2 to 684 KJ/mol for the Zn/Al2O3-SiO2 catalyst) considering the desorption rate as a temperature function. The presence of a metal on the support showed to have an important significance in the chloromethane condensation. The oxide class catalyst presented a better performance toward the production of hydrocarbons. Especial mention to the ZnO/Al2O3-SiO2 that, in a gas phase basis, produced C3 83 % max. and C4 63% max., respectively, in the temperature of 450 oC and 20 hours on stream. Hydrogen was produced exclusively in the FeO/Al2O3-SiO2 catalysts (15 % max., T = 550 oC and 5,6 h on stream) and Ni/SiO2-Al2O3 (75 % max., T = 400 oC and 21,6 h on stream). All the catalysts produced methane (10 ? 92 %), except for Ni/Al2O3-SiO2 and CrO/Al2O3-SiO2. In the deactivation study two models were proposed: The parallel model, where the product production competes with coke formation; and the sequential model, where the coke formation competes with the product desorption dessorption step. With the mass balance equations and the mechanism proposed six parameters were determined. Two kinetic parameters: the hydrocarbon formation constant, 8,46 10-4 min-1, the coke formation, 1,46 10-1 min-1; three thermodynamic constants (the global, 0,003, the chloromethane adsorption 0,417 bar-1, the hydrocarbon adsorption 2,266 bar-1), and the activity exponent of the coke formation (1,516). The model was reasonable well fitted and presented a satisfactory behavior in relation with the proposed mechanism / S?lica alumina amorfa e modificada por impregna??o incipiente de precursores de ferro, n?quel, zinco e cromo foram sintetizados na forma de ?xido e reduzidos, tendo sido posteriormente avaliados como catalisadores na convers?o de clorometano em hidrocarbonetos. Propriedades texturais e t?cnicas din?micas em temperatura programada foram usadas para a determina??o das propriedades ?cidas dos materiais. Um modelo termodin?mico para representar a capacidade de adsor??o e dessor??o de clorometano foi avaliado. Dois tipos de rea??es foram abordados. No primeiro, o clorometano foi convertido cataliticamente a hidrocarbonetos (T = 300 450 oC e m = 300 mg) em um reator de leito fixo catal?tico com controle de fluxo, press?o e vaz?o m?ssica e, no segundo, com o suporte puro (T = 300 oC e m = 250 mg) foi estudado a rea??o de desativa??o do catalisador pelo coque em um micro adsorvedor com monitoramento gravim?trico. O teor de metal no suporte (2,5 %) e o percentual de clorometano na mistura (10 %) foram mantidos constantes durante os experimentos. Com os resultados obtidos foram avaliadas a convers?o e a seletividade dos produtos gasosos, ou seja, H2, CH4, C3 e C4 bem como a energia da etapa de dessor??o (75,2 KJ/mol para o Ni/Al2O3-SiO2 e 684 KJ/mol para o catalisador Zn/Al2O3-SiO2), considerando a taxa de adsor??o do g?s em fun??o da temperatura. A presen?a do metal no suporte mostrou uma import?ncia significativa em termos de atividade na rea??o de condensa??o do clorometano. Os catalisadores na forma de ?xido apresentaram melhor desempenho para obten??o de hidrocarbonetos. ? poss?vel destacar o ZnO/Al2O3-SiO2 que , em termos de constituinte gasoso, produziu apenas C3 (M?x. de 83 %) e C4 (M?x. de 63%), respectivamente, na temperatura de 450 oC e 20 horas de rea??o,. O g?s hidrog?nio foi formado exclusivamente com os catalisadores FeO/Al2O3-SiO2 (M?x. de 15 %, T = 550 oC e tempo de rea??o de 5,6 h) e Ni/SiO2-Al2O3 (M?x. 75 %, T = 400 oC e tempo de rea??o de 21,6 h). Todos os catalisadores produziram o g?s metano (10 ? 92 %), salvo os do tipo Ni/Al2O3- SiO2 e CrO/Al2O3-SiO2. No estudo com o suporte puro foram propostos dois modelos de iii desativa??o, do tipo paralelo, onde a forma??o do produto compete com a forma??o de coque e o sequencial, onde a etapa de dessor??o ? a competidora. Com as equa??es do balan?o de massa baseadas no mecanismo proposto foram determinados duas constantes cin?ticas (a primeira de valor 8,01?10-4 min-1, relacionada ? etapa da forma??o de hidrocarbonetos e a segunda, 1,46?10-1 min-1, ao coque depositado no s?tio do material), tr?s constantes de equil?brio (a global 0,003, relativa ao clorometano 0,417 bar-1, e a de forma??o de hidrocarbonetos 2,266 bar-1) e o do perfil do fator de atividade (1,516). Em termos de ajustes, o modelo representou um comportamento satisfat?rio em rela??o ao mecanismo proposto

En érigeant un cadre théorique réunissant les concepts de fixation spatiale et d’état d’exception, la présente thèse vise à brosser un portrait des Zones franches d’exportation (ZF) à la lumière du cas salvadorien entre les années 1980 et 2000. L’objectif est de proposer des pistes de réflexion quant au caractère exceptionnel des ZF et leur insertion dans les cycles d’accumulation capitalistes. Sont ainsi abordés les discours légitimant la création des ZF et leur maintien, les moyens financiers, juridiques et logistiques déployés pour permettre leur construction, les relations de pouvoir exceptionnelles qui caractérisent les rapports intra et extra-ZF ainsi que les intérêts que les ZF servent. Cette thèse se veut donc une tentative de compréhension du processus général à l’oeuvre derrière les ZF, dans l’objectif de mieux cibler les possibilités de résistance. *** This thesis aims to analyse the emergence of export processing zones (EPZ) through a theoretical framework that combines the concepts of spatial fix and state of exception. Taking as an illustration the Salvadoran case in the 1980-2000 period, the objective is to suggest means for reflecting on the exceptional character of the EPZ and their insertion in cycles of capitalist accumulation. The thesis will also explore the discourses legitimizing the creation and the retention of EPZ, the logistical, juridical and financial means deployed to allow their construction, the exceptional power relations that characterize the intra and extra-EPZ relations and the interests served by EPZ. This thesis is thus an attempt to encompass the general process behind the EPZ, in order to identify the resistance possibilities.

Studien undersöker fenomenet undervisning med bildkonst och dess potential för ett growth mindset hos barnen. Growth mindset är en del i en psykologisk inlärningsmodell för att öka barns och elevers mindset att välkomna utmaningar och därigenom uppleva att de lyckas. Forskning kring estetiska lärprocesser för ämnesöverskridande lärande berör främst matematik och litteracitet, men har inte studerats som ett verktyg för uppnå ämnesövergripande effekter på lärandet, som delvis kan exemplifieras med growth mindset. Syftet är att undersöka fenomenet förskollärares undervisning med bildkonst, genom att fördjupa kunskapen om verksamma pedagogers upplevelser kring bildskapande konstarter med barn i förskolan. Frågeställningarna är; Vilka är förskollärarnas resonemang och upplevelser om bildkonstens betydelse för barns lärande?, Vilka psykologiska meningsbärande enheter uppstår i förskollärares resonemang om undervisning med bildkonst? samt Vilka effekter av ett growth mindset framträder i förskollärarnas berättelser om arbetet med bildkonst?. Studien har utgått från fenomenologisk vetenskapsteori tillsammans med psykologisk teori om fixed och growth mindset. Narrativ intervju användes tillsammans med video stimulated reflection i studiens datainsamling. The Descriptive Phenomenological Psychological Method används som analysmetod. Studiens resultat mynnade ut i fyra psykologiska meningsbärande enheter; Förskollärares ledarskap, Bildundervisning i förskolan, Bildkonst som mål eller medel? och Skapandets roll i förskolan. I studien visas en växelverkan mellan effekter av ett fixed- och ett growth mindset i förskollärarnas resonemang kring fenomenet undervisning med bildkonst. Växelverkan tydliggjordes i förskollärarnas resonemang kring deras pedagogiska ledarskap och syfte när de i undervisning med bildkonst tog hänsyn till barnens intressen och skapande. Och samtidigt efterleva läroplanen och rikta barnens lärande mot bildundervisningens innehåll. Slutsatsen är att undervisning med bildkonst har potential att uppnå effekten av ett growth mindset i barns lärande.

För att studera hur omställningen från vertikal till horisontell energiutvinning kommer att påverka samhället har två fallstudier gjorts. Fallstudierna tillsammans med teorin om socialekologiska fix har använts för att analysera de socialekologiska transformationerna som sker på landskap och politiken som finns kring dessa transformationer. En fallstudie har studerat vindkrafts projektet Markbygden i Norrbottens län och den andra studerar vindkraftsetableringen i Östergötlands län. Dessa fallstudier har genomförts genom en kvalitativ studie i form av intervjuer med aktörer som är med och påverkar samt påverkas av dessa vindkraftsetableringar. Fallstudierna visar att landskapet har förändrats fysiskt av byggnationen av vindkraftverken vilket har bidragit till en transformation av markanvändningen. Karteringar som har gjorts i samband med vindkraftsetablering har påverkat hur människor använder och förhåller sig till marken samt hur ägandeförhållandena ser ut. Vidare har vindkraftsetableringen i Östergötland och Norrbotten lett till olika konflikter som exempelvis störningar av ljus och buller samt konflikter med renskötseln som tidigare bedrivits i området Markbygden. Dessa konflikter har alltså uppkommit till följd av den landskapstransformation som har skett i samband med vindkraftsutbyggnaden. I Norrbotten och Östergötland är en ekonomisk kompensation respektive en markhyra aktuell, dock anses dessa vara otillräckliga för att kompensera för den förlust av betesmark för renar som sker i Norrbotten respektive för de besvär lokalbefolkningen upplever med bullret i Östergötland. Slutligen visar resultatet även på att den största drivkraften för företag att etablera vindkraft är vinst och därmed sker otillräckliga karteringar av vind och markanvändning vilket försvårar implementeringen av vindkraft. Slutsatserna för denna rapport är därmed att olika kartläggningar av främst vind har förändrat markanvändningen och andra verksamheter som tidigare bedrivits i landskapet har begränsats och i stor utsträckning ersatts av produktion av vindkraft. Då vindkraften i Östergötland och Norrbotten har byggts ut med otillräckliga kartläggningar som inte tar de sociala relationerna i beaktning har dessa olika konflikter uppstått. / To study how the transition from vertical to horizontal energy recovery will affect society, two case studies have been conducted. The case studies, together with the theory of socio-ecological fixes, have been used to analyze the socio-ecological transformations that take place on landscapes and the politics that exist around these transformations. The first case study concerned the wind power project called Markbygden in Norrbotten County and the second case study concerned wind power establishment in Östergötland County. These case studies were conducted through a qualitative study in the form of interviews with actors who are involved in and are affected by these wind power establishments. The case studies show that the landscape has changed physically by the construction of wind turbines, which has contributed to a transformation of land use. Mappings that have been made in correlation with wind power establishment have affected how people use and relate to the land and what the ownership conditions look like. Furthermore, the establishment of wind power in Östergötland and Norrbotten has led to various conflicts such as disturbances caused by light and noise as well as conflicts with reindeer husbandry that was previously conducted in the Markbygden area. These conflicts have thus arisen as a result of the landscape transformation that has taken place in connection with the expansion of wind power. In Norrbotten and Östergötland, financial compensation and land rent are current, however, these are considered insufficient to compensate for the loss of grazing land for reindeer that occurs in Norrbotten and for the problems the local population experiences with the noise in Östergötland. Finally, the results also show that the biggest driving force for companies to establish wind power is profit and thus insufficient mapping of wind and land use takes place, which makes it more difficult to implement wind power. The conclusions of this report are thus that various mappings of mainly wind have changed land use and other activities previously conducted in the landscape have been limited and to a great extent been replaced by the production of wind power. As wind power in Östergötland and Norrbotten has expanded with insufficient mappings that disregard existing social relations, the various conflicts have arisen.

This thesis examines the relationship between Cold War science fiction fix-up novels and social cycle theory. The study engages with textual, cultural, and comparative analysis to elucidate and analyze links between the fix-up novel format, a cyclical conception of human history, and the Cold War setting of the construction and publication of three SF novels. The objects of this study are three Cold War era fix-up novels with origins in World War II pulp science fiction magazine short stories: The Martian Chronicles by Ray Bradbury, City by Clifford D. Simak, and A Canticle for Leibowitz by Walter M. Miller Jr. The project examines these three novels alongside the reflective nature of the fix-up novel format, the authors' interactions with social cycle theory, and the Cold War cultural considerations of ideological instability and the threat of annihilation. By examining these works through the lens of retroactive continuity, social cycle theory, and the Cold War cultural imaginary, this thesis demonstrates the complex interplay between literature, culture, and history, and the ways in which SF authors have used their works to engage with the pressing concerns of their time. / Master of Arts / The Cold War era novels The Martian Chronicles by Ray Bradbury, City by Clifford D. Simak, and A Canticle for Leibowitz by Walter M. Miller Jr. share origins in pulp science fiction magazine short stories. These authors consolidated and revised previously published short stories to produce these works, known as fix-up novels. These three fix-up novels interact with representations of human progress as cyclical or non-linear. This project examines how the Cold War setting of the authors may have influenced science fiction authors' conceptions of human progress as cyclical. This thesis studies how the revision process of creating fix-up novels combined with the transition from World War II to the societal anxieties of the Cold War may have impacted the cultural messages of these novels.
