Este trabalho trata da relação entre competição, estrutura e agência nas Relações Internacionais. Ele se estrutura em três partes. A primeira parte contextualiza o estudo na agenda de pesquisa dos Estudos Estratégicos Internacionais. Para tanto, discute-se a pertinência do debate agente–estrutura, bem como delimitam-se os pressupostos ontológicos que nortearão o restante do trabalho. A segunda parte é o artigo. Analisam-se os efeitos da competição no processo de evolução dos sistemas políticos internacionais, sistemas políticos nacionais e estados. Por conta disso, discute-se a ontologia de cada objeto de análise e, em seguida, busca-se os mecanismos causais que conectam suas respectivas trajetórias evolutivas. De acordo com os atores e meios envolvidos, três dimensões de competição social são identificadas: competição internacional; construção do estado; e concorrência regulada. A hipótese de trabalho é que os resultados das interações entre as estratégias escolhidas pelos agentes para enfrentar o tipo de competição com que se deparam causam mudanças na estrutura dos sistemas políticos internacionais, nacionais e nas características das organizações políticas estatais. Na terceira parte, discute-se as implicações teóricas e práticas decorrentes do trabalho, bem como são assinaladas perspectivas para a continuação da agenda de pesquisa. Sugere-se que a incorporação de conceitos e categorias desenvolvidas pela literatura de Teoria de Sistemas e da Complexidade é fundamental para a superação de dicotomias ontológicas e epistemológicas nas ciências sociais. Ademais, argumenta-se que o aperfeiçoamento das organizações políticas é indissociável da compreensão de que a busca por defesa e segurança pelos estados não é apenas uma força destruidora, mas também pode produzir efeitos que potencializam a coesão social e expandem direitos fundamentais. Logo, propõe-se que a agenda de pesquisa decorrente desse trabalho deverá se debruçar sobre a questão de quais são as condições em que interações competitivas contribuem para o surgimento de organizações políticas capazes de sobreviverem e atuarem no sistema político internacional contemporâneo, bem como proverem segurança, bem-estar e direitos políticos para seus cidadãos. / This paper deals with the relationship among competition, structure and agency in International Relations. The study is structured in three parts. The first part contextualizes the work in the research agenda of the International Strategic Studies. Therefore, we discuss the relevance of the agent-structure debate, and delimit the ontological assumptions and that will guide the rest of the study. The second part is the article. It analyzes the effects of competition in the process of evolution of international political systems, national political systems and states. On that account, discusses the ontology of each object of analysis, and then seeks the causal mechanisms that connect their evolutionary trajectories. According to the actors and means involved three dimensions of social competition are identified: international competition; construction of state; and regulated competition. The working hypothesis is that the results of the interactions among the strategies chosen by agents to cope with the kind of competition they encounter cause changes in the structure of international political systems, national political systems and in the characteristics of the state political organizations. In the third part, it is discussed theoretical and practical implications resulting from study, and also prospects for the continuation of the research agenda. It is suggested that the incorporation of concepts and categories developed by Systems and Complexity Theory is fundamental to overcoming ontological and epistemological dichotomies in the social sciences. Moreover, it is argued that the improvement of our political organizations is inseparable from the understanding that the search for security and defense by states is not only a destructive force, but can also produce effects that enhance social cohesion and expansion of fundamental rights. Therefore, it is proposed that the research agenda derived from the study should lean over the question of what are the conditions under which competitive interactions contribute to the emergence of political organizations able not only to survive and act in the contemporary international political system, but also provide security, welfare, and political rights to its citizens.

Human language is both a cognitive and a cultural phenomenon. Any evolutionary account of language, then, must address both biological and cultural evolution. In this thesis, I give a mainly cultural evolutionary answer to two main questions: firstly, how do working systems of learned communication arise in populations in the absence of external or internal guidance? Secondly, how do those communication systems take on the fundamental structural properties found in human languages, i.e. systematicity at both a meaningless and meaningful level? A large, multi-disciplinary literature exists for each question, full of apparently conflicting results and analyses. My aim in this thesis is to survey this work, so as to find any commonalities and bring this together in order to provide a minimal account of the cultural evolution of language. The first chapter of this thesis takes a number of well-established models of the emergence of signalling systems. These are taken from several different fields: evolutionary linguistics, evolutionary game theory, philosophy, artificial life, and cognitive science. By using a common framework to directly compare these models, I show that three underlying commonalities determine the ability of any population of agents to reliably develop optimal signalling. The three requirements are that i) agents can create and transfer referential information, ii) there is a systemic bias against ambiguity, and iii) some mechanism leading to information loss exists. Following this, I extend the model to determine the effects of including referential uncertainty. I show that, for the group of models to which this applies, this places certain extra restrictions on the three requirements stated above. In the next chapter, I use an information-theoretic framework to construct a novel analysis of signalling games in general, and rephrase the three requirements in more formal terms. I then show that we can use these 3 criteria as a diagnostic for determining whether any given signalling game will lead to optimal signalling, without the requirement for repeated simulations. In the final, much longer, chapter, I address the topic of duality of patterning. This involves a lengthy review of the literature on duality of patterning, combinatoriality, and compositionality. I then argue that both levels of systematicity can be seen as a functional adaptation which maintains communicative accuracy in the face of noisy processes at different levels of analysis. I support this with results from a new, minimally-specified model, which also clarifies and informs a number of long-fought debates within the field.

A inexistência de uma regra única que discipline a prevalência de norma constitucional federal sobre norma constitucional estadual, e vice-versa, no sistema federativo brasileiro, é tratada aqui enfocando tão somente os vínculos que dizem respeito aos agentes públicos. Embora as normas constitucionais federais devessem, em princípio, aterem-se à estrutura estatal, à divisão de competências e prerrogativas dos poderes, e às garantias individuais e sociais, os constituintes brasileiros preocuparam-se em regular matérias que recebem o status de constitucionais porque foram guindadas a tanto, seja pela força dos fatos sociais ou, até mesmo, por mero fisiologismo. Nesse terreno, mais próprio da legislação comum, é que está o epicentro das Emendas Constitucionais que têm reflexos nas Constituições Estaduais e em toda a legislação. Cuida-se aqui deste fenômeno e das suas conseqüências nas normas que regulam a Administração Pública e seus agentes. / The fact that there is not an unique rule about the predominance of the precept of the Federal Constitution over the State Constitution and vice versa in the brazilian federative system, is here treated focusing only the public agents relations. Although the federal constitutional rules should mainly deal with State structure, competence division and prerogatives, as well as individual and social garanties, brazilian constituent worried about themes that received the status of constitutional norms because they were turned to it, either by the social facts force, either by pure physiologism. In this field, peculiar to ordinary law, is situated the epicenter of the constitutional amendment that reflects in the State Constitutions and in all the ordinary law. Here this phenomenon is treated as well as its consequences in the laws that regulate Public Administration and its agents.

O envelhecimento populacional faz com que saber entender e relacionar-se com os idosos se torne um desafio para esse personagem na boa execução de suas funções. Assim, é fundamental sabermos o que os ACS pensam e conhecem sobre o idoso e sobre o envelhecimento. Nosso estudo tem os objetivos de descrever e analisar o perfil sociodemográfico, a experiência de convivência e trabalho com idosos, as atitudes em relação à velhice e os conhecimentos que os ACS de Marília-SP têm sobre o envelhecimento. Foi realizado um estudo transversal, de caráter descritivo onde se entrevistaram os 213 agentes comunitários das 12 Unidades Básicas de Saúde (UBS) e 29 Unidades de Saúde da Família (USF) de Marília. Os dados foram coletados através de um questionário sociodemográfico e dois instrumentos: uma escala de atitudes em relação à velhice e um questionário para avaliar conhecimentos gerontológicos. Os resultados mostraram que o quadro de ACS de Marília é formado predominantemente por adultos jovens, do sexo feminino, casados, com mais de 12 anos de escolaridade e inseridos nesta atividade há mais de 6 anos. Verificamos que a maioria dos profissionais relatou experiência com grupo de idosos e convivência intra-domiciliar com pessoas desta faixa etária, porém menos da metade referiu capacitação no tema “envelhecimento”. Comparando UBS e USF, nas primeiras, onde a população idosa é maior, os ACS são de faixa etária mais alta, têm mais tempo de trabalho, maior convivência intra-domiciliar com idosos, mais experiência com grupos de idosos e referem mais capacitação em envelhecimento.

Population ageing makes knowing, understanding and relating to the elderly a challenge to these players in the performance of their duties. Hence, it is fundamental to know what CHAs think and know about the elderly and ageing. Our study aimed at describing and analyzing the socio-demographic profile of CHAs, their experience of being and working with the elderly, their attitudes in relation to old age and the knowledge that CHAs from Marília-SP have about ageing. A cross-sectional descriptive study was conducted in which the 213 community agents from the 12 primary care units (UBS) and the 29 Family Health Units (UFS) in Marília were interviewed. Data were collected by means of a socio-demographic questionnaire and two instruments: a scale of attitudes in relation to old age and a questionnaire to evaluate gerontological knowledge. Results showed that the team of CHAs predominantly comprises young adults who are married, have attended school for longer than 12 years and have worked in this activity for over 6 years. It was observed that most of the professionals reported to have experience with the group of elderly people as well as intradomiciliary contact with individuals at that age range. However, fewer than half of the CHAs reported to have been trained on the topic of “ageing”. By comparing UBSs and USFs, in the former, where the elderly population is larger, the CHAs are older, have been working longer, have more intradomicilary contact with the elderly and more experience with elderly groups. They also report to have been better trained on ageing. Concerning attitudes in relation to old age, the CHA’s positive evaluations occurred particularly in ...

abstract: The Hohokam of central Arizona left behind evidence of a culture markedly different from and more complex than the small communities of O'odham farmers first encountered by Europeans in the sixteenth and seventeenth centuries A.D. Archaeologists have worked for well over a century to document Hohokam culture history, but much about Pre-Columbian life in the Sonoran Desert remains poorly understood. In particular, the organization of the Hohokam economy in the Phoenix Basin has been an elusive and complicated subject, despite having been the focus of much previous research. This dissertation provides an assessment of several working hypotheses regarding the organization and evolution of the pottery distribution sector of the Hohokam economy. This was accomplished using an agent-based modeling methodology known as pattern-oriented modeling. The objective of the research was to first identify a variety of economic models that may explain patterns of artifact distribution in the archaeological record. Those models were abstract representations of the real-world system theoretically drawn from different sources, including microeconomics, mathematics (network/graph theory), and economic anthropology. Next, the effort was turned toward implementing those hypotheses as agent-based models, and finally assessing whether or not any of the models were consistent with Hohokam ceramic datasets. The project's pattern-oriented modeling methodology led to the discard of several hypotheses, narrowing the range of plausible models of the organization of the Hohokam economy. The results suggest that for much of the Hohokam sequence a market-based system, perhaps structured around workshop procurement and shopkeeper merchandise, provided the means of distributing pottery from specialist producers to widely distributed consumers. Perhaps unsurprisingly, the results of this project are broadly consistent with earlier researchers' interpretations that the structure of the Hohokam economy evolved through time, growing more complex throughout the Preclassic, and undergoing a major reorganization resulting in a less complicated system at the transition to the Classic Period. / Dissertation/Thesis / NetLogo code, software, and model initialization data. / Ph.D. Anthropology 2013

Context. Agent based models are used to simulate complex systems by using multiple agents that follow a set of rules. One such model is the boid model which is used to simulate movements of synchronized groups of animals. Executing agent based models partially or fully on the GPU has previously shown to increase performance, opening up the possibility for larger simulations. However, few articles have previously compared a full GPU implementation of the boid model with a multi-threaded CPU implementation. Objectives. The objectives of this thesis are to find how parallel execution of boid model performs when executed on the CPU and GPU respectively, based on the variables frames per second and average boid computation time per frame. Methods. A performance benchmark experiment will be set up where three implementations of the boid model are implemented and tested. Results. The collected data is summarized in both tables and graphs, showing the result of the experiment for frames per second and average boid computation time per frame. Additionally, the average results are summarized in two tables. Conclusions. For the largest flock size the GPGPU implementation performs the best with an average FPS of 42 times over the single-core implementation while the multi-core implementation performs with an average FPS 6 times better than the single-core implementation. For the smallest flock size the single-core implementation is most efficient while the GPGPU implementation has 1.6 times slower average update time and the multi-cor eimplementation has an average update time of 11 times slower compared to the single-core implementation.

Nesta dissertação apresentamos uma arquitetura para um Agente Emocional Hedonista, inspirada parcialmente em diversas destas contribuições. Para tanto, desenvolvemos um controlador que confere comportamento autônomo a uma criatura artificial. Duas implementações foram realizadas: uma baseada em um algoritmo heurístico e a outra, em um algoritmo genético. Ambas as implementações consideram dois níveis de controle hierárquico: um nível de controle direto e um nível de decisão de metas. Desenvolveu-se um simulador para a criatura artificial onde diferentes controladores podem ser acoplados à criatura, por meio da rede, rodando como processos separados. Utilizou-se em ambos os casos "Medo", "Fome" e "Curiosidade" como metáforas emocionais. O trabalho sinaliza, entre outros resultados, a adequação dessas metáforas como design patterns para a construção do comportamento do agente, sugerindo um novo paradigma de programação no desenvolvimento de agentes, que substitui uma programação orientada a casos de uso por uma programação orientada a propósitos / Abstract: The use of emotions as a computational metaphor for the development of autonomous agents control systems has received many contributions in the recent literature. In this work, we present an architecture for an Hedonistic Emotional Agent, partially inspired in many of such contributions. For that, we developed a controller which confers autonomous behavior to an artificial creature. Two implementations were performed: the first based on the generation of an heuristic algorithm, and the second one using a genetic algorithm. Both of them considers two layers of control: a low level of direct control and a higher level of goal decision. We developed a simulator for the artificial creature where different controllers can be attached to the creature through the network, running as different processes. We used in both cases "Fear", "Hunger" and "Curiosity" as emotional metaphors. The work signalizes, among others results, the adequacy of these metaphors as "design patterns" for the construction of agent behavior, suggesting a new programming paradigm in the development of agents, which exchanges a use-case oriented programming for a purpose-oriented new way of programming / Mestrado / Engenharia de Computação / Mestre em Engenharia Elétrica

Estas interações foram possíveis pela abertura do anel epóxido, presente na extremidade da cadeia do precursor, com os centros básicos das aminas. As sínteses destes novos agentes foram confirmadas por espectroscopia na região do infravermelho, mostrando a ausência das bandas referentes às deformações simétrica e assimétrica do anel epóxido. Os agentes sililantes foram, então, utilizados na modificação da superfície da sílica gel e também nas sínteses de filossilicatos de níquel e cobalto. A modificação da sílica foi realizada através das rotas homogênea e heterogênea, originando materiais com estruturas semelhantes, quando foram empregados os mesmos sililantes, porém, houve uma superioridade significante no grau de funcionalização através da rota homogênea, como comprovado pela análise elementar. As sínteses dos filossilicatos organofuncionalizados foram realizadas através do processo sol-gel, cujas estruturas são similares à do talco natural, ou seja, filossilicatos de estrutura 2:1 trioctaédricos, sendo que os metais níquel e cobalto ocupando os sítios octaédricos. Todos os materiais sintetizados foram caracterizados por análise elementar, espectroscopia na região do infravermelho, ressonância magnética nuclear dos núcleos de 13C e 29Si e termogravimetria. Informações estruturais dos filossilicatos ainda foram fornecidas por difratometria de raios X e microscopia eletrônica de varredura. Os materiais foram usados em adsorção de íons bário e cobre, sendo que as sílicas modificadas apresentaram maior capacidade de adsorção de bário que os filossilicatos. O comportamento contrário foi observado para os íons cobre, que apresentou maior adsorção com os filossilicatos, que contêm maiores quantidades de grupos orgânicos pendentes. Este fato pode ser explicado devido ao maior raio iônico do bário, o que possivelmente dificulta a interação com os centros básicos pendentes no espaço interlamelar. Os resultados de calorimetria com o cobre indicaram que os processos de adsorção apresentaram valores exotérmicos de entalpia, com valores negativos de energia livre de Gibbs e valores positivos de entropia. Esses dados termodinâmicos indicam que a interação cátion/centro básico na interface sólido/líquido é favorável / Abstract: Two new silylating agents were synthesized through individual reactions of ethanolamine and diethanolamine molecules with 3- glicidoxypropyltrimethoxysilane. Through these interactions the epoxide ring in the extremity of the precursor chain was opened by the action of the basic centers of the amines. These syntheses were confirmed by infrared spectroscopy, which spectra showed the absence of symmetrical and asymmetrical bands of the epoxide group. The silylating agents were applied on silica gel surface organofunctionalization and also to synthesize nickel and cobalt phyllosilicates. Chemical modification of silica was performed through homogeneous and heterogeneous routes, originating materials with similar structures when the same silylating agent was employed, nevertheless there was an increase of the degree of functionalization on the silicas prepared through homogeneous route, as confirmed by elemental analysis. The syntheses of organofunctionalized phyllosilicates was achieved through sol-gel process, whose structures are similar to natural talc, that is, phyllosilicates with 2:1 trioctahedral structures, with nickel and cobalt metals located in the octahedral sites. All synthesized materials were characterized by elemental analysis, infrared spectroscopy, nuclear magnetic resonance of 13C and 29Si and thermogravimetry. Additional structural information was obtained by X-ray diffraction and scanning electron microscopy techniques. The materials were used on barium and copper adsorption, in which the modified silicas presented higher capacity on barium adsorption than phyllosilicates. On the other hand, it was observed that copper acted more effectively on organofunctionalized phyllosilicates, in agreement with their higher amount of pendant organic groups. This fact can be explained due to the higher barium ionic radius, which can difficult its interaction with pendant basic centers into the interlamellar space. The calorimetry results with copper showed that the adsorption processes of the metallic cations onto pendant basic centers gave exothermic enthalpies, negative Gibbs free energies and positive entropy values. This set of thermodynamic data indicates that cation/basic center interaction at the solid/liquid interface is favorable / Doutorado / Quimica Inorganica / Doutor em Quimica
