Como resultado, uma nova geração de aplicações está emergindo e consequentemente novos modelos mentais se fazem necessários para lidar elas. Neste contexto, Máquinas Sociais aparecem como um modelo promissor para o desenvolvimento de software. Entretanto, é um tema novo, com conceitos e definições provenientes de diferentes campos de pesquisa, o que torna o entendimento unificado do conceito um esforço desafiador. Nesta tese, nós fornecemos uma base conceitual mais coerente para entender máquinas sociais como um paradigma unificado para descrever, projetar e implementar aplicações e serviços sociais emergentes. Para isso, primeiramente revisitamos o conceito de relacionamento e estendemos a noção de máquinas sociais como um modelo de abstração comum a ser utilizado para fundir elementos computacionais e sociais em software. Em segundo lugar, para descrever máquinas sociais, apresentamos diretrizes para a análise que abordam algumas questões relacionadas com o exercício de engenharia de sistemas existentes. Em terceiro lugar, definimos a Social Machine-oriented Architecture (SoMAr) - um estilo arquitetural híbrido para projetar máquinas sociais através da combinação de diferentes princípios da prática atual da engenharia de software. Por fim, discutimos as experiências e lições aprendidas com a aplicação do paradigma de máquinas sociais em diferentes contextos. / The open, distributed approach of the Web and the relationship’s prevalence of applications and services are transforming both the way we develop software and how they operate and interact with each other. As a result, a novel breed of applications is emerging, and consequently new mental models are needed to deal with them. In this context, Social Machines appear as a promising model for developing software. However, it is a fresh topic, with concepts and definitions coming from different research fields, making a unified understanding of the concept a somewhat challenging endeavor. In this thesis we provide a more coherent conceptual basis for understanding Social Machines as a unified paradigm to describe, design and implement emerging social applications and services. To do that, we revisited the concept of relationship and extend the notion of Social Machines to establish a common abstraction model that is used for blending computational and social elements into software. Second, to describe social machines, this proposal presents an analysis guideline that addresses some issues related to the engineering exercise of existing systems. Third, we provide the Social Machine-oriented Architecture (SoMAr) - a hybrid style to design social machines through the combination of different principles from current software engineering practice. Finally, we discuss the experiences and lessons learned from applying the social machines paradigm in different contexts.

O presente trabalho é uma avaliação do efeito da administração de ocitocina nasal sobre o perfil de ativação do sistema nervoso autônomo e níveis salivares de cortisol, buscando compreender a relação entre esses vetores dentro da perspectiva da teoria polivagal e da concepção da ocitocina como um peptídeo de ação pró-social. A hipótese testada foi se o sistema pró-social, mediado pela ocitocina, exerce um efeito de ativação no ramo parassimpático, diminuindo o nível salivar de cortisol, comprovando o efeito anti-stress dessa molécula, ao desligar o sistema de alarme, reação filogenética para a preparação fisiológica para a interação social (relaxamento e tranquilidade). Para tanto, utilizou-se do Trial Social Stress Test, cuja tarefa é falar em público, situação em que parâmetros autonômicos foram medidos em sujeitos humanos, assim como o nível de cortisol salivar avaliado, em dois grupos: um experimental (com administração de ocitocina) e um controle (com administração de placebo) e em dois momentos (pré e pós stress social), relacionando-os a dados de personalidade (teste Bateria Fatorial da Personalidade). Os achados foram indicativos que a ocitocina exerce um efeito inibitório notável sobre os níveis de cortisol, não encontrando dados conclusivos sobre o vinculo ou não da atividade parassimpática relacionada com a presença da ocitocina e baixo nível de cortisol, embora se tenha encontrado forte influência da presença da ocitocina na atividade cardíaca (mediada pelo sistema nervoso autônomo). O fator de personalidade se mostrou bastante relevante nos resultados de cortisol e efeitos de ocitocina, correlacionados com o índice de Neuroticismo e se encontrou indicativos de que outros fatores de personalidade podem também ser importantes / The present work is an evaluation of nasal administration effect of oxytocin over the activation profile of the autonomic nervous system and salivary levels of cortisol, seeking to understand the relationship between these vectors within the perspective of the polyvagal theory and the conception of oxytocin as a pro social peptide. The hypothesis tested was whether the pro-social system, mediated by oxytocin, exerted an activation effect over the parasympathetic branch, reducing the salivary level of cortisol, proving the anti-stress effect of this molecule, when the alarm system was turned off, phylogenetic reaction to the physiological preparation for social interaction (relaxation and tranquillity). For this purpose, the Trial Social Stress Test was used, whose task is to speak in public, in which its autonomic parameters were measured, as well as the level of salivary cortisol evaluated, in two groups: one experimental (with oxytocin administration) and one control (with placebo administration) and at two moments (pre and post social stress), relating these results with personality data (Personality Factor Battery test). The findings were indicative that oxytocin exerts a remarkable inhibitory effect on cortisol levels, and we did not find conclusive data about the relationship or not of the parasympathetic activity related to the presence of oxytocin and low cortisol level, although strong oxytocin influence was found over the cardiac activity (mediated by the autonomic nervous system). The personality factor was shown to be very relevant in the cortisol and oxytocin effects correlated with the Neuroticism Index and it was found that other personality factors may also be important

L'objectif principal de la thèse consiste à explorer des problématiques propres aux sciences sociales et à les étudier à l'aide d'outils issus du champ de la physique statistiques et des systèmes complexes. Le travail de la thèse s'est ainsi décliné sur trois grands sujets dont la problématique principale est la question de l'agrégation d'entités individuelles en une structure collective. Le premier sujet est centré sur un exemple paradigmatique de l'émergence d'un comportement collectif macroscopique inattendu à partir de règles individuelles simples: le modèle de ségrégation de Schelling. Nous avons notamment proposé une résolution analytique inédite de ce modèle et nous avons étudié analytiquement et via des simulations l'impact de différentes formes de coopération entre agents individuels sur le comportement collectif global. Cette thématique a été développée à la fois d'un point de vue économique et d'un point de vue physique. Le second sujet porte sur l'exploration de bases de données bibliométriques. Nous avons ainsi produit des 'cartes des sciences' représentant le champ des systèmes complexes (sa structure interne étant décrypté via une analyse des références utilisées par ~140000 articles) ou encore l'état de la recherche au sein d'un établissement tel que l'ENS de Lyon. Enfin, le troisième thème porte sur l'élaboration de modèles basés sur des outils des sciences 'dures' mais sociologiquement fondés. Nous présentons ainsi le processus d'élaboration d'un modèle construit avec une équipe de sociologues. Enfin, nous développons un modèle d'opinion répondant spécifiquement à une question: l'existence de structures qui durent à partir d'entités qui ne durent pas. / This thesis explores the problems raised by the aggregation of entities into a global, collective level, an old problem encountered in many fields of science. We work on three projects related to the aggregation problem in social systems, using tools derived from statistical physics, and more generally quantitative tools. The first project focus on a paradigmatic model of the emergence of puzzling macroscopic behavior from simple individual rules, Schelling's segregation model. We hence propose an analytical resolution of this model and we studied analytically and via simulations the effect of several forms of cooperation between individual agents on the collective behavior. These questions are tackled in a mutually beneficial way for both economics and physics. The second project is based on the exploration of huge databases on scientific literature. We hence produce several 'science maps' representing the fields of complex systems (its internal structure and coherence being analysed through the references used by ~140000 relevant articles) and the research carried out in a scientific institution such as the ENS de Lyon. Finally, the third project deals with the elaboration of models of social phenomena based on natural sciences tools but sociologically grounded. We hence present the elaboration process of a model built with a team of sociologists. We then propose an opinion model specifically designed to explore a single question: the existence of lasting structure from non lasting entities.

In the shift towards a sustainable society, there have been varying interpretations of what this will mean for the social sphere. Using the parameters for social sustainability presented in the framework for strategic sustainable development (FSSD), this research sought to assist sustainability practitioners in identifying and eliminating the creation of or contribution to barriers that undermine the individual’s capacity to meet their needs. In doing so, the researchers explored the processes of social systems and employed a systems thinking perspective to examine how an organization could, through the intentional structuring of its processes, work to eliminate their contributions to arriers. From this research, characteristics of processes that move an organization towards socially sustainable development were identified as cooperation, transparency, openness, inclusiveness and involvement, around which a guidebook was developed to promote organizational reflection and examination of processes in regards to these characteristics and fundamental human needs. / This thesis aims to provide useful guidance for transforming organizational processes to better reflect a consideration of human needs. It seeks to address structures which act as barriers to the capacity of people to actualize their needs, and proposes a set of characteristics of processes that help to eliminate these barriers. / <p>andbenaim@yahoo.com.br - Andre Benaim acollins01@gmail.com - Amber C.

Abstract This thesis aims to contribute to the restructuring of the research field of ICT in education by trying to reduce the complexity of the research with an analysis of the research from the perspective of research of science. The analysis provides a second order observation of research especially from a paradigm point of view. The concept of paradigm has been re-defined by applying Niklas Luhmann's (1995) theory of social systems. The main research task of this thesis is to describe the paradigms structuring scientific communication in research on ICT integration in education. The research questions here are based on the understanding that paradigms are structures of the social communicative systems of science, creating expectations for the researcher about the scientific nature of the research. The definition of the paradigm as a selective structure in a social communicative system of science implicitly defines that the communication within the system is language by nature. In this research, to separate it from linguistics, the focus is in the use of language in research context, not in language itself. In practice, the paradigms of research on ICT integration in education are analyzed through qualitative analysis of metaphors containing ontological assumptions of research and rhetoric convincing the scientific community of the scientific nature and the interest of research. The sample articles have been selected according to such a criteria that they can be seen representing the core of the scientific communication in the field. From the education point of view, the mainstream of research on ICT integration in education has led to an immersion of the learning theoretical foundation of the research into techno-economic paradigms - and in a sense led to fading of broader educational and social perspectives. The mainstream of the research is shadowing the research that has social and cultural approaches and critical research interests related to a changing education system and global educational problems. Although the research puts emphasis on constructive learning theories, techno-economic paradigms of the research field continue the tradition of instructional technology, which is framing the concept of "e-Education". This mainstream is not viable in solving the current problems of education globally. This is not to say that the research field of ICT in education is growing obsolete. On the contrary, the research is needed urgently but it should focus also on the broader educational and social developments in a global context. / Tiivistelmä Tämä tutkimus liittyy tieto- ja viestintätekniikan opetuskäytön poikkitieteellisen tutkimusalueen jäsentämiseen ja selkiinnyttämiseen. Tutkimuksen lähestymistapa on tutkimuksen tutkimus, jossa tutkimusaluetta tarkastellaan reflektiivisesti ns. toisen tason havainnointina. Tutkimuksessa lähestytään tieto- ja viestintätekniikan opetuskäytön tutkimusaluetta paradigma -käsitteen avulla, joka määritellään Niklas Luhmann'in (1995) sosiaalisen järjestelmän teoriaa hyödyntäen tieteellisen kommunikaatiojärjestelmän valikoiviksi rakenteeksi. Tutkimusongelmat keskittyvät näiden rakenteiden kuvailemiseen olettaen, että nämä valikoivat rakenteet luovat tutkijoille odotuksia tutkimuksen perusolettamuksista. Paradigmat tieteellisen kommunikatiivisen järjestelmän rakenteina perustuvat kieleen, jota käytetään tutkimusten raportoinnissa sekä muussa tieteellisessä kommunikaatiossa. Tässä tutkimuksessa näitä rakenteita tutkitaan kansainvälisissä tutkimusartikkeleissa esiintyvien tieto- ja viestintätekniikan opetuskäyttöön liittyvien metaforisten ilmauksien sekä tutkimuksen lähtökohtiin ja intresseihin liittyvän retoriikan kautta. Tulkinnassa käytetään kielen käytön tutkimuksen menetelmiä, pitäytyen metaforisten ilmausten sekä retoriikan yhdenmukaisuuksien ja erojen analysoimisessa. Analyysin tarkoituksena on jäsentää tieteellisen kommunikaation paradigmaattisia rakenteita. Tutkimuksen tuloksena voidaan lyhyesti todeta, että tieto- ja viestintätekniikan opetuskäytön tutkimusta luonnehtii voimakas instrumentaalinen sekä teknis-taloudellinen suuntaus. Suurin osa tutkimusta hallitsevista metaforista sekä paradigmoista voidaan nähdä tämän laajemman suuntauksen osina. Orastava sosio-kulttuurinen tutkimus-suuntaus on selvästi edellä mainitun pääsuuntauksen varjossa. Oppimisteoreettisesti orientoitunut opetusteknologinen tutkimus korostaa yhteistoiminnallisuutta ja sosiaalista kontekstia oppimisen edellytyksenä. Tutkimusparadigmojen näkökulmasta myös tämä tutkimusorientaatio noudattaa pääosin teknis-taloudellista tutkimussuuntausta. Tämä on havaittavissa teknologian instrumentaalisuuden korostamisessa sekä tutkimuksen perustumisessa pääosin luonnontieteelliseen tutkimustraditioon. Tutkimus ei siten erotu olennaisesti teknis-taloudellisesta tutkimus- ja kehitystyöstä erilliseksi suuntaukseksi. Tutkimuksen keskeiseksi käsitteeksi nousevat erityisesti "e-education" ja "e-learning", joiden varaan uusi koulutus- ja oppimismuoto on jäsentymässä. Sosio-kulttuurinen tutkimusorientaatio, institutionaaliset tutkimuskohdetta kuvaavat metaforat sekä koulutuksen muutosta korostavat tutkimusintressit ovat tutkimusalan kokonaisvaltaisen jäsentymisen ja globaalien koulutuksellisten ongelmien kannalta tärkeitä. Poikkitieteellisen, eri tieteenaloja ja metaforia syntetisoivan viitekehyksen sekä kulttuuritutkimuksellisen lähestymistavan korostaminen ovat tieto- ja viestintätekniikan opetuskäytön tutkimuksen kehittymisen kannalta keskeisiä.

Sveriges riksdag har antagit 16 nationella miljökvalitetsmål. Miljömålsarbetet kan ses som en del av de insatser som krävs för att vi ska skapa en hållbar utveckling, vilken är en målsättning som ska genomsyra hela vårt samhälle. Myndigheter har tilldelats ansvaret för att de nationella miljömålen implementeras, men att målen nås är hela samhällets ansvar. I denna avhandling analyseras de kommunikativa villkoren i det svenska miljömålsarbetet. Studien bygger till stor del på erfarenheter som kommit till uttryck i de fokusgruppsintervjuer som genomförts med miljömålsansvariga tjänstemän på centrala, regionala samt kommunala myndigheter. Såväl politiska dokument som myndighetsrapportering har analyserats och satts i relation till tjänstemännens erfarenheter. Utifrån teorier om målstyrning, implementeringsprocesser och kommunikation i sociala system analyseras sedan kommunikativa barriärer och broar, hur de visar sig och kan förklaras. Avhandlingen visar att det finns kommunikationsbarriärer men också broar i miljömålsarbetet. När nya mål och beslut ska omsättas i etablerade organisationer uppstår kommunikationsbarriärer både inom myndigheter och i kommunikationen med andra aktörer i samhället. Att implementera beslut om ett nytt målstyrningssystem i en komplex omvärld med dess ekologiska såväl som sociala system är ingen friktionsfri process. Olika systemkoder som är i bruk kan förklara en del av problematiken, men även otydlighet i målsystem och bristande resurstilldelning. En utmaning inför framtiden blir att skapa information som ger resonans och skapar mening i olika sociala system och därigenom bidrar till möjligheterna att nå de nationella miljökvalitetsmålen. / In 1999, the Swedish Parliament introduced a new management by objectives (MBO) approach to sustainable development politics with the adoption of 15 national environmental quality objectives, ambitious objectives that are to be achieved within 20 years. Overall responsibility for implementing and evaluating the environmental objectives at the national level is assigned to central agencies but also for business and the public. This dissertation analyses the communicative conditions within the environmental objectives implementation process. The analysis in this study has a social system theoretical approach. The system with National Environmental Quality Objectives has both pros and cons. The National Environmental Quality Objectives has been difficult to communicate in established organisations as well as different sector agencies and departments. A challenge for the future is to adjust information and communication to a differentiated society on purpose to get resonance and understanding about the efforts needed to fulfil the National Environmental Objective’s achievement.

The thesis deals with the Cuban system of social security. The work focuses on general operation of social systems in Latin America and compares them with the Cuban social system. Thus, the thesis aims to explore the system of social security in Cuba, to describe its advantages and disadvantages and to show why the system is sometimes considered as more effective then other systems in this region. Attention has also been paid to the ageing of the population and how Cuba deals with this problem.

The aim of this thesis is to analyze the effective possibilities of civilizing practices in the contemporary societies. For this, two fundamental hypotheses guided, so surreptitious but emphatic, the arguments of this analysis: the first would be the denial of the modern belief in the broad and inexorable powers of the rationality . both the rationality which pointed to their universally positive results, as that which was a scathing criticism of its inability to produce a civilly shared world; the second refers to the denial of a postmodern critical deconstruction of rationality, which resulted in the world of the relativism and the consequent configuration of the world without ethical appreciation. On occasion, we analyze the metaphysics that animated the modernity: the tireless attempt to separate the rationality from the negative influence of the irrationality data. However, not all thinkers surrendered to the rationalist project of the modernity. Freud, Arendt, Foucault, for example, realized that the combination of various disparate elements: it.s, simultaneously, rational and irrational; factual and evaluative; regular and contingent. It was these and other important authors who helped us to think about the second working hypothesis of this thesis, namely, that meaning of the terms modernity and civilization, as well as all the other terms relating to them, are constructed in their daily use, social practices, the collective shocks and political struggles. Thus, there is no meanings that precede their subscriptions in the world, i.e. the world is the result of the effect of each thing, each object, each process. With this, we are not saying that particular meaning of civilization cannot remain active in the orientation of collective conduct (of societies), as if we were denying the possibility of creating lasting consensus. We are not positioned in favor of the relativism; to the contrary, we have argued that, even in contemporary societies, can be viewed attempts to develop productive practices civilizing. Finally, what articulate such hypotheses is the understanding that the practices of any kind are studded end to end by relations of power, relation of force and interests, which provide the tone and texture of the scientific, social, political and cultural dynamics, which characterize, deeply, the development of the civilizing action. / O objetivo central desta tese é analisar as possibilidades efetivas de práticas civilizatórias nas sociedades contemporâneas. Para isso, duas hipóteses fundamentais nortearam, de maneira sub-reptícia, mas enfática, as argumentações desta análise: a primeira seria a recusa da crença moderna nos poderes amplos e inexoráveis da racionalidade tanto daquela que apontava para seus resultados universalmente positivos, quanto da que consistia numa crítica mordaz à sua incapacidade de produzir um mundo civilizatoriamente compartilhado; a segunda refere-se à recusa de uma desconstrução crítica pós-moderna da racionalidade, que resultou no mundo do relativismo e da consequente configuração do mundo vazio de valoração ética. Na ocasião, analisamos a metafísica que animava a modernidade: a tentativa incansável de separar a racionalidade da influência negativa dos dados da irracionalidade. Entretanto, nem todos os pensadores se renderam ao projeto racionalista da modernidade. Freud, Arendt, Foucault, por exemplo, perceberam que o processo civilizatório é ontologicamente constituído pela mistura prática de vários elementos díspares: é, simultaneamente, racional e irracional; factual e valorativo; regular e contingente. Foram esses e outros importantes autores que nos ajudaram a pensar sobre a segunda hipótese de trabalho desta tese, ou seja, a de que o significado dos termos modernidade e civilização, bem como todos os outros termos que lhes são referentes, são construídos em seu uso cotidiano, nas práticas sociais, nos embates coletivos e nas lutas políticas. Sendo assim, não existem significados prévios às suas inscrições no mundo, ou seja, mundo é resultado do efeito de cada coisa, cada objeto, cada processo. Com isso, não se quer dizer que determinado significado de civilização não possa manter-se ativo na orientação de condutas coletivas (de sociedades), como se estivéssemos negando a possibilidade de constituição de consensos duradouros. Não nos posicionamos em favor do relativismo, ao contrário, temos defendido que, mesmo nas sociedades contemporâneas, podem ser visualizadas produtivas tentativas de elaboração de práticas civilizatórias. Por último, o que articula tais hipóteses é o entendimento de que as práticas, de qualquer natureza, são cravejadas de ponta a ponta por relações de poder, por relações de força e de interesses, que fornecem o tom e a textura das dinâmicas científicas, sociais, políticas e culturais, dinâmicas essas que caracterizam, sobremaneira, o desenvolvimento da ação civilizatória.

A teoria da sociedade de Niklas Luhmann, construída como teoria de sistemas sociais, encontra freqüentes críticas voltadas contra seu pretendido distanciamento moral e político no diagnóstico da sociedade contemporânea. Pesa sobre a teoria de sistemas sociais a generalização de um juízo prematuro conforme o qual ela se reduziria a uma sociologia conservadora de tendência tecnocrata, uma herdeira radicalizada do positivismo. Contudo, e contrariamente a essa percepção geral, a teoria de sistemas sociais parece ter um potencial crítico ainda inexplorado em toda a sua extensão, e que pode ser ativado por uma leitura que permita expandir o alcance da teoria. Essa expansão pode ser promovida quando a teoria de sistemas sociais é mobilizada para fundamentar uma teoria da comunicação de matriz materialista (capítulo 1), capaz de permitir que sua categoria fundamental a autopoiese seja compreendida em estreita relação com a apresentação do capital por Karl Marx (capítulo 2) e confrontada com uma teoria do capitalismo (capítulo e 3). Na seqüência, a teoria de sistemas sociais é empregada para dar conta das múltiplas dimensões da desigualdade social (capítulo 4) e da dinâmica dos conflitos e das contradições da sociedade atual (capítulo 5). Esta tese propõe um primeiro passo na direção de uma recepção crítica da obra teórica de Niklas Luhmann. Trata-se de testar os limites e as possibilidades da teoria de sistemas sociais. / Niklas Luhmanns theory of society, built as theory of social systems, is usually met with criticisms pointed against its intended moral and political distance in diagnosing contemporary society. Weights upon the social systems theory the generalization of a premature judgement according to which, this theory would be reduced to a conservative sociology with technocratic tendencies, a radicalised heir to positivism. However, and against this usual perception, the theory of social systems seems to have a critical potential not yet developed in its full extension and which may be activated by an interpretation capable of expanding its range. This extension can be carried out when we handle social systems theory in order to ground a materialistic theory of communication (chapter 1), enabling a close connection between its main conceptual category autopoiesis and Karl Marxs presentation of the capital (chapter 2), as well as a confrontation with a theory of capitalism (chapter 3). Afterwards, social systems theory is used to explaining the manifoldness of social inequality (chapter 4) and the dynamics of contemporary conflicts and societal contradictions (chapter 5). This thesis proposes a first step in the direction of a critical reception of Niklas Luhmanns theoretical work. It is a matter of testing limits and possibilities of social systems theory

Die Arbeit verfolgt die These, dass es sich beim Markt nicht um ein wirtschaftliches Phänomen handelt. Vor dem Hintergrund des wirtschaftssoziologischen Diskurses plädiert sie entsprechend für einen trans-ökonomischen Marktbegriff, auf dessen Grundlage sich auch Märkte in Erdregionen und Erdzeitaltern beobachten lassen, in denen Gesellschaft nicht funktional primär-differenziert ist oder war.
