Résumé :
In the present paper, we have briefly reviewed Sznajd's sociophysics model and its variants, and we also have proposed a simple Sznajd-like sociophysics model based on Ising spin system to explain the time evaluation of resistance probability of a closed community against occupation. Using a numerical method, we have shown that the time evaluation of resistance probability of community has a nonexponential character, which decays as stretched exponential, independent of the number of soldiers in one-dimensional model. Furthermore, it has been astonishingly found that our simple sociophysics model belongs to the same universality class of random walk process on the trapping space.

Résumé :
The article describes the elements of the sociophysical approach in relation to the study of processes at an enterprise that produces aircraft engines. The interpretation of the sociophysical approach of financial sustainability for the enterprise is given. It is shown that the use of standard methods of financial and economic analysis of an enterprise in the cases of long-life cycle is limited and leads to contradictory conclusions. The comparison of the results of sociophysical modeling with the results of modeling obtained using the well-known methods of financial and economic analysis of the enterprise have be done. The concept of the sociophysical function and necessary formulas are given. The formulation of the problem of forming a toolkit for sociophysical assessment of sustainability of an enterprise using sociophysical potentials is formulated. Models of the dynamics of the potentials of the sources of financing the assets of the enterprise, the financial sustainability are represented.

Résumé :
We present our research on the application of statistical physics techniques to multi-group social conflicts. We identify real conflict situations of which the characteristics correspond to the model. We offer realistic assumptions about conflict behaviors that get factored into model-generated scenarios. The scenarios can inform conflict research and strategies for conflict management. We discuss model applications to two- and three-group conflicts. We identify chaotic time evolution of mean attitudes and the occurrence of strange attractors. We examine the role that the range of interactions plays with respect to the occurrence of chaotic behavior.

Résumé :
We review a series of models of sociophysics introduced by Galam and Galam et al. in the last 25 years. The models are divided into five different classes, which deal respectively with democratic voting in bottom-up hierarchical systems, decision making, fragmentation versus coalitions, terrorism and opinion dynamics. For each class the connexion to the original physical model and techniques are outlined underlining both the similarities and the differences. Emphasis is put on the numerous novel and counterintuitive results obtained with respect to the associated social and political framework. Using these models several major real political events were successfully predicted including the victory of the French extreme right party in the 2000 first round of French presidential elections, the voting at fifty–fifty in several democratic countries (Germany, Italy, Mexico), and the victory of the "no" to the 2005 French referendum on the European constitution. The perspectives and the challenges to make sociophysics a predictive solid field of science are discussed.

This thesis applies statistical physics concepts and methods to quantitatively analyze complex systems. This thesis is separated into four parts: (i) characteristics of earthquake systems (ii) memory and volatility in data time series (iii) the application of part (ii) to world financial markets, and (iv) statistical observations on the evolution of word usage. In Part I, we observe statistical patterns in the occurrence of earthquakes. We select a 14-year earthquake catalog covering the archipelago of Japan. We find that regions traditionally thought of as being too distant from one another for causal contact display remarkably high correlations, and the networks that result have a tendency to link highly connected areas with other highly connected areas. In Part II, we introduce and apply the concept of "volatility asymmetry", the primary use of which is in financial data. We explain the relation between memory and "volatility asymmetry" in terms of an asymmetry parameter λ. We define a litmus test for determining whether λ is statistically significant and propose a stochastic model based on this parameter and use the model to further explain empirical data. In Part III, we expand on volatility asymmetry. Importing the concepts of time dependence and universality from physics, we explore the aspects of emerging (or "transition") economies in Eastern Europe as they relate to asymmetry. We find that these emerging markets in some instances behave like developed markets and in other instances do not, and that the distinction is a matter both of country and a matter of time period, crisis periods showing different asymmetry characteristics than "healthy" periods. In Part IV, we take note of a series of findings in econophysics, showing statistical growth similarities between a variety of different areas that all have in common the fact of taking place in areas that are both (i) competing and (ii) dynamic. We show that this same growth distribution can be reproduced in observing the growth rates of the usage of individual words, that just as companies compete for sales in a zero sum marketing game, so do words compete for usage within a limited amount of reader man-hours.

Résumé :
O estudo de sistemas sociais sempre foi visto como fora do escopo da física. No entanto, nos últimos anos, com o desenvolvimento da mecânica estatística e da aprendizagem de máquinas, em conjunto com recentes avanços na neurociência, tornou-se possível a criação de diversos modelos no intuito de estudar quantitativamente grandezas antes consideradas majoritariamente qualitativas. Dentre os problemas considerados está a moralidade, bem como suas consequências para as dinâmicas de opinião. Mais especificamente, considera-se relevante estudar como se dá a mudança de opiniões dentro de uma sociedade, bem como estratégias para convencer uma população a alterar sua direção moral. Utilizando um modelo baseado em agentes, na qual cada agente é representado por um vetor moral e utiliza uma estratégia de aprendizagem ótima para o cenário professor/aluno, estudamos a influência de duas estratégias de convencimento no comportamento macroscópico de nossa sociedade modelo. Tomando como base a aprendizagem sequencial sem a presença de ruído, e o fato de que seleção de exemplos na borda da dúvida gera um decaimento exponencial do erro de generalização em redes neurais artificiais, estudamos o efeito desta técnica como estratégia de convencimento populacional, assim como a comparação de sua eficácia com a estratégia padrão, na qual os exemplos são selecionados uniformemente.
The study of social systems was always seen as out of scope for the physical sciences. However, in the last years, with the rapid development of statistical mechanics and machine learning, along with recent advances in the field of neuroscience, it became possible to create a wide range of models with the objective to investigate quantitatively aspects of sociology that were mainly considered as qualitative features. Within the considered problems lies the issue of morality, as well as it\'s consequences to opinion dynamics. More specifically, it is considered relevant to understand how the opinion change dynamics undergoes inside a society, as well as strategies to convince a population to alter it\'s moral direction. Using an agent based model, in which each agent is represented by a moral vector and has an optimally performing algorithm in the professor/student scenario, we study the influence of two different convincement strategies on the macroscopic behaviour of our model society. In the online learning framework, without any noise, it is known that examples distributed perpendicular to the student achieve a exponential decay in it\'s generalization error. Therefore, we study the effect of this technique as a population convincement strategy, along with it\'s efficiency compared to the standard strategy, in which examples are selected uniformly.

Résumé :
Nos últimos anos, uma míriade de modelos de propagação de opinião foram propostos, motivados pelo interesse crescente dos físicos por problemas interdisciplinares tanto em sociologia, quanto em economia e biologia. Um dos objetivos desse trabalho é unificar alguns desses modelos em uma mesma formulação. Para isso, generalizamos a noção de confiança limitada para o que chamamos de regras de confiança, que podem ser interpretadas como a introdução de viéses ou preconceitos nas interações de agentes com opiniões distintas. Munidos dessa formulação, nos propusemos a estudar como modelos que promovem localmente conformidade (o que está de acordo com experimentos para grupos pequenos conduzidos por psicólogos), poderiam gerar diversidade globalmente (explicando a persistência de pontos de vista distintos em sociedades, por exemplo). Nós estudamos o campo médio do modelo do votante e de variantes do modelo Sznajd. Aplicando ferramentas de sistemas dinâmicos, conseguimos resolver analiticamente o comportamento qualitativo dos modelos na ausência de ruído e desenvolvemos uma teoria de perturbação para o modelo Sznajd com ruído infinitesimal, que nos forneceu um retrato parcial do comportamento na presença de ruído. Na ausência de ruído, chegamos a conclusão que o modelo do votante se comporta de maneira completamente diferente, enquanto que os outros modelos tem essencialmente o mesmo comportamento. Também fizemos simulações em redes Barabási-Albert e Watts-Strogatz para os modelos votante e Sznajd e, em colaboração com o grupo de pesquisa do Institute for Complex Systems and Mathematical Biology da Universidade de Aberdeen, estudamos um modelo de biodiversidade que pode ser encarado como uma variante do modelo do votante em uma rede quadrada. As nossas conclusões apontam que os resultados de campo médio podem ser compreendidos através de conexões com teoria de grafos e que os diversos modelos simulados se comportam em um certo sentido da mesma maneira, reforçando a idéia de universalidade entre eles (na verdade é essencial que existam aspectos universais no comportamento humano para que a modelagem de sistemas sociais seja factível, dadas as dificuldades óbvias de se construir um modelo realista para uma pessoa ou uma sociedade). Grosso modo, em todos os sistemas estudados, a coexistência ou não de pontos de vista diferentes parece depender mais crucialmente da rede e do tipo de regra de confiança, do que de outros detalhes específicos do modelo.
In the recent years, a great number of opinion propagation models were proposed, motivated by the increasing interest among physicists in interdisciplinary problems, not only in sociology, but also in economics and biology. One of the goals of this work is to unify some of these models under a same formulation. In order to do that, we generalized the notion of bounded confidence to what we called confidence rules, that can be interpreted as the introduction of biases and prejudices in the interactions among agents holding differing points of view. Using this formulation, we decided to study how models that locally breed conformity (what is in accordance with experiments conducted by psichologists for small groups) could sustain diversity globally (explaining the persistence of different points of view in societies, for example). We studied the mean field version of the voter model and of variants of the Sznajd model. We used dynamical systems techniques and were able to solve analytically the qualitative behaviour of the models in the absence of noise and developed a perturbation theory for the Sznajd model with infinitesimal noise, that yielded a partial picture of the behaviour with noise. In the absence of noise, we found that the voter model has a completely different behaviour, while the other models have essentially the same behaviour. We also did simulations in Barabási-Albert and Watts-Strogatz networks for the voter and the Sznajd models and we collaborated with the research group of the Institute for Complex Systems and Mathematical Biology from the University of Aberdeen, studying a biodiversity model that can be seen as a modification of the voter model in a square lattice. Our conclusions point that the mean field results can be understood through connections with graph theory problems and that the different models that were simulated, in some sense, have the same behaviour, reinforcing the idea of universality for these models (due to the obvious difficulties in modelling human beings in a reliable and realistic way, some degree of universality in human behaviour is actually essential, in order for social modelling to be feasible). Roughly speaking, in all the systems that were studied, the coexistence or not of differing opinions, seems to depend more strongly on the network and on the type of confidence rule used, than in other specific details of the model.

Nesta dissertação foram estudados alguns modelos vetoriais que pretendem modelar e descrever alguns aspectos de sistemas sociais e de sua organização cultural. Partimos do modelo de Axelrod, um processo estocástico definido em uma rede, e introduzimos uma pequena alteração no modelo que desencadeou mudanças qualitativas interessantes, especialmente o surgimento de uma tensão superficial, que leva ao aparecimento de estados metaestáveis e de regiões culturais mais fixamente localizadas no espaço. Através da ótica da mecânica estatística e de extensas simulações computacionais, exploramos alguns dos aspectos que julgamos mais importantes na caracterização desse rico modelo.
Axelrod\'s model for cultural dissemination is a discrete vector representation for modeling social and cultural systems. In this work we have studied it and other related models, and a subtle change in the model\'s rule was proposed. Our slight alterations to the model yielded significant qualitative changes, specifically the emergence of surface tension, driving the system to metastable states. Using concepts from statistical mechanics and extensive numerical simulations, we explored some of the aspects that better describe the rich model devised, such as its transient and stationary behaviour.

Résumé :
The study of how social organizations work, change and develop is central to sociology and to our understanding of the social world and its transformations. At the same time, the underlying principles of organizational dynamics are extremely difficult to investigate. This is partly due to the difficulties of tracking organizations, individuals and their interactions over relatively long periods of time. But it is also due to limitations in the kinds of quantitative methods used to tackle these questions, which are for the most part based on regression analysis. This thesis seeks to improve our understanding of social organizing by using models to explore and describe the logics of the structures and mechanisms underlying organizational change. Particular emphasis is given to the modeling process, the use of new concepts and analogies, and the application of interdisciplinary methods to get new insights into classical sociological questions. The thesis consists of an introductory part and five studies (I-V). Using Swedish longitudinal data on employment in the Stockholm Region, the studies tackle different dimensions of organizational dynamics, from organizational structures and growth processes to labor mobility and employment trajectories. The introductory chapters contextualize the studies by providing an overview of theories, concepts and quantitative methods that are relevant for the modeling of organizational dynamics.  The five studies look into various aspects of organizational dynamics with the help of complementary data representations and non-traditional quantitative methods. Study I analyzes organizational growth statistics for different sectors and industries. The typically observed heavy-tailed statistical patterns for the size and growth rate distributions are broken down into a superposition of interorganizational movements. Study II models interorganizational movements as a labor flow network. Organizations tend to be more tightly linked if they belong to the same ownership sector. Additionally, public organizations have a more stable connection structure. Study III uses a similarity-based method called homogeneity analysis to map out the social space of large organizations in the Stockholm Region. A social distance is then derived within this space, and we find that the interorganizational movements analyzed in Studies I and II take place more often between organizations that are closer in social space and in the same network community. Study IV presents an approach to organizational dynamics based on sequences of employment states. Evidence for a positive feedback mechanism is found for large and highly sequence-diverse public organizations. Finally, Study V features an agent-based model where we simulate a social influence mechanism for organizational membership dynamics. We introduce a parameter analogous to a physical temperature to model contextual influence, and the familiar growth distributions are recovered as an intermediate case between extreme parameter values. The thesis as a whole provides suggestions for a more process-oriented modeling approach to social organizing that gives a more prominent role to the logics of organizational change. Finally, the series of methodological tools discussed can be useful for the analysis of many other social processes and more broadly for the development of quantitative sociological methods.

Résumé :
INTRODUCTION: The interest of this research is the assessment of the quality of architecture and urban planning through human experience. Specially, focusing on the critical point of view of child population and their families about the physical and social school environment. OBJECTIVES: To develop a new methodology, which is able to link the different areas of children's experience, the representation of the environment by children and the quality of school's environment-configuration. A new administrative tool able to complete the existing indicators of the Child Friendly Cities Program, while continuing the work of the GIRAS research group, started in the 70s and based on an approach to the architectural design and urban planning project from the historical and social fields. METHODOLOGY: Qualitative & quantitative multidisciplinary methodology based on the analysis of variables related to: the representation of environments built by children, the data on the experience and the quality of the school's environment configuration. Thanks to the element "school", the concentration of data collection, is possible (through models built by children, surveys carried out among children, families and teachers, and participant observation of the environment by the author of the thesis). RESULTS: The results confirm: on the one hand, the lack of links between the factors of the environment's configuration and the representation's quality. On the other hand, the positive influence on the representation of some specific aspects about the family and the children's experience, and some socioeconomic, sociodemographic and family psychosocial aspects. CONCLUSION: The methodological proposal, as concluded by this work, becomes a tool to assess, both in a playful and pedagogical way and in a rigorous and administrative manner, the socio-physical relationship of children and their families with the school, the school¿s environment and the city where the school is located, through the participation of the whole educational community (children, families and teachers).
L'interès d'aquesta recerca es troba en el fet d'avaluar la qualitat de l'arquitectura i l'urbanisme a través de l'experiència humana i, especialment, en el desenvolupament d'una mirada crítica des de la població infantil i les seves famílies en la relació a l'entorn escolar físic i social. OBJECTIUS: Elaborar una nova metodologia capaç de vincular els diferents àmbits de l'experiència infantil, la representació de l'entorn per infants i la qualitat de la configuració de l'entorn escolar. Una nova eina administrativa capaç de completar els indicadors existents del Programa Ciudades Amigas de la Infancia, i, alhora, de donar continuïtat a la tasca del grup de recerca GIRAS, iniciada als anys 70 i fonamentada en una aproximació al projecte d'arquitectura i l'urbanisme des del medi ambient històric i social. METODOLOGIA: Estructura tri metodològica multidisciplinària, fonamentada en l'anàlisi de variables qualitatives en relació a: la representació d'entorns construïts per infants, les dades sobre l'experiència i la qualitat de la configuració de l'entorn escola; gràcies a l'element "escola", el qual fa possible la concentració de l'obtenció de dades (a través de maquetes construïdes per infants; enquestes realitzades a infants, famílies i professorat; i l'observació directa de l'entorn per part de l'autor de la tesi). RESULTATS: Els resultats confirmen: d'una banda, la inexistència de vincles entre els factors de la configuració de l'entorn i la qualitat de les representacions; i de l'altra, la influència positiva sobre la representació d'alguns aspectes concrets sobre l'experiència familiar i infantil, així com d'algunes característiques socioeconòmiques, sociodemogràfiques i psicosocials familiars. CONCLUSIÓ: La proposta metodològica, tal com conclou aquest treball, es converteix en una eina per mesurar la relació sociofísica dels infants i les seves famílies amb l'escola, l'entorn escolar i la ciutat on s'ubica l'escola, d'una manera tant lúdica i pedagògica com rigorosa i administrativa i a través de la participació de tota la comunitat educativa (infants, famílies i professorat).

Résumé :
O Dilema do Prisioneiro (DP) é o jogo mais proeminente da Teoria dos Jogos devido à emergência da cooperação entre jogadores egoístas. O comportamento de cada jogador depende da estratégia que ele adotada e do seu ganho, que é determinado em função dos parâmetros do DP (T, R, P e S) e do número z de vizinhos com que ele joga. Portanto, a estrutura espacial dos jogadores não é relevante. Em nosso trabalho, utilizamos um autômato celular unidimensional onde cada jogador pode cooperar ou desertar ao interagir, simetricamente, com seus z vizinhos mais próximos. O sistema proposto nos permitiu realizar um estudo exaustivo do espaço de parâmetros para as estratégias evolucionárias Darwiniana (EED) e a Pavloviana (EEP) e compara-las. A geometria unidimensional nos possibilita obter os mesmos resultados dos sistemas em dimensionalidade arbitrária d, além de apresentar várias vantagens em relação a elas. No sistema que propomos os efeitos de borda são menores, exige menos tempo para a execução das simulações numéricas, permite variar o valor de z e é fácil obter uma representação visual da evolução temporal do sistema. Tal visualização simplifica a compreensão das interações entre os jogadores, pois surgem padrões nos agrupamentos de cooperadores/desertores, semelhantes aos pertencentes às classes dos autômatos celulares elementares. O estudo destes padrões nos permite compreender simplesmente a emergência da cooperação ou deserção nos sistemas. A evolução temporal do sistema que adota a EED gera um diagrama de fases muito rico com a presença das fases cooperadora, desertora e caótica. Já para a EEP, obtivemos um novo resultado analítico para as transições de fase, que neste caso são: cooperadora e quasi-regular. O estudo numérico exaustivo determinou as regiões do espaço de parâmetros onde acontecem cada uma das fases, e os efeitos da auto-interação podendo assim validar os resultados teóricos. O estudo do caso particular T = 1, tradicionalmente considerado como trivial, mostrou que ele apresenta comportamentos inusitados. Nossa principal contribuição para o estudo do DP é a obtenção de um novo paradigma. A geometria unidimensional com interação de vizinhos simétricos permitiu a visualização da evolução de padrões de cooperadores e desertores, o cálculo analítico de Tc para a EEP e o estudo de T = 1 para tais sistemas.
The Prisoner Dilemma (PD) is the most prominent game of the Game Theory due to emergency of the cooperation between selfish players. The behavior of each player depends on his/her strategy and the payoff, which is determined in function of the PD parameters (T, R, P and S) and by the number z of neighbors with whom he/she plays. Therefore, the spatial structure of the players does not matter. In our work, we have used a one-dimensional cellular automaton where each player can cooperate or defect when interacting, symmetrically, with his/her z nearest neighbors. The considered system allowed us to carry out an exhaustive exploration of the parameters space for the Darwinian Evolutionary Strategy (EED) and Pavlovian (EEP) and compares them. One-dimensional geometry makes possible to us get the same results of the systems in arbitrary d dimensional networks, besides, it presents some advantages. For the system that we proposed compared to the others dimensional networks, the boundary effects are less present, it needs less time for run the numerical simulations, it allows to vary the z value and is easier to get the visual representation of the system temporal evolution. Such visualization simplifies the understanding of the interactions between the players, therefore patterns appear in the clusters of cooperator/defectors, and these patterns belong to the elementary cellular automata classes. The study of these patterns allows them to understand in an easy way the emergence of the cooperation or defection in the systems. The temporal evolution of the system that adopts the EED yields a very rich phases diagram with the presence of cooperative, defective and chaotic phases. By the other hand, for the EEP, we have got a new analytical result for the phase transitions that in this case are: quasi-regular and cooperative. The exhaustive exploration study determines the regions on the parameters space where happen each phases occurs, and the effect of the self-interaction and thus validate the theoretical results. The study of the particular case T = 1, traditionally considered as trivial one, showed that it presents unusual behaviors, that we will present. Our main contribution for the study of the DP is the attainment of a new paradigm. One-dimensional geometry with interaction of symmetrical neighbors allowed to visualizes the evolution of cooperators and defectors patterns, the analytical result for Tc for the EEP and the study of T = 1 for such systems.

In 2018 Taiwanese municipal elections, the six Kuomintang special municipality candidates didn’t have high voter support at the early stage. The Kuomintang candidate at Kaohsiung gradually became famous and won voter support. This trend helped him to win the Kaohsiung election and also helped Kuomintang to win three elections in Taiwan’s six special municipalities. By applying the factor analysis to the polling data, we find there were two major factors for special municipality polls, and the larger one can be identified as the “Han current”, which is almost a monotonically increasing time series in the later stage of the elections. We use the Galam model to fit the polling data and predict the election results. The time period for the data fitting is selected according to relevant news and social events. Inspired by the “Han current” collective phenomena, we also propose a new model, the magnetic field model, in which a global magnetic field influences all the voters. The tunable parameter in the Galam model only acts on the term with the same number of voter support in an even-voter party, while the magnetic field parameter acts on every term in the model. When the Galam model and the magnetic field model is used to predict election results, we find that adopting small parties of voters will increase the accuracy of prediction. If there are several news scandals or social events affecting the polls, it is better to choose the time period starting from the news or social events closer to the polling day.

Résumé :
Lo scopo di questa attività di ricerca è stato quello di studiare i processi individuali e le dinamiche di piccolo gruppo in interazione/comunicazione virtuale. Una prima fase di ricerca si è concentrata sulle dinamiche di comunicazione e affinità tra individui coinvolti in discussione di piccolo gruppo via chat, una seconda fase ha indagato le relazioni tra personalità, opinione, affinità e comunicazione e infine in una terza fase attraverso i dati sperimentali si propone un modello sociofisico ad agenti di dinamica di opinione.
