Nesta direção desenvolver uma abordagem que descreva os coletivos sociotécnicos articulados a partir e através deste permanente conflito entre doping e antidoping é a via de entrada para uma melhor compreensão das relações entre esporte e tecnologia na atualidade. Seja, na performance atlética, que passa a ser compreendida como uma realidade intrinsecamente heterogênea a partir dos diversos artefatos sociotécnicos, conceituais e materiais envolvidos em sua constituição. Como nos contra investimentos realizados pelas instituições esportivas com o intuito de coibir e detectar as práticas de doping. No intuito de apreender como estas relações complexas produzem diversos dispositivos técnicos e conceituais que atuam nas intersecções entre o esporte profissional e a tecnociência, constituindo novas práticas e saberes sobre o corpo do atleta.

With the continuously demarcated boundary between doping and anti-doping, between licit and illicit in sport, the limits of the body nature and the human are traced. In this direction the dissertation develops an approach that describes the pleadings from sociotechnical collectives and through this ongoing conflict between doping and antidoping is the entry pathway to a better understanding of the relationship between sport and technology nowadays. An athletic performance shall be understood as a reality intrinsically heterogeneous composed through the socio-technical relations, conceptual and material involved in its constitution , as in the investments made by the sports institutions in order to curb and detect doping practices. In order to grasp how these complex relationships produce various technical and conceptual devices that operate at the intersections between professional sport and technoscience, building new practices and knowledge about the athlete's body. Finally, tensing the anthropos as a conceptual figure, both ethically questioning what we know and understand as human as disciplinary, highlighting the methodological limits of anthropological analysis, when it happens as disciplinary project, which aims at understanding the Human.

Cette thèse s’inscrit dans le cadre théorique très général de la conception des systèmessociotechniques complexes. Elle est appliquée au système de l'Appareil à Gouverner des sous-­‐marins. Elle traite, tout particulièrement, de l'étape d’allocation des fonctions entre l’homme et la machine.L’objectif des premiers travaux a été de tester un système automatisant la phase d’analyse de l’information mise à disposition du barreur. Deux expérimentations ont évalué les effets d’une interface "écologique" sur la performance, la charge de travail et la conscience de la situation de barreurs réalisant une tâche de pilotage sur simulateur.Une deuxième phase a consisté à définir différentes solutions d’allocation dynamique des fonctions entre l’homme et la machine dans le système de pilotage de sous-­‐marin. Une expérimentation a évalué l’apport d’une réallocation à la machine de la gestion du cap et/ ou de l'immersion, en fonction de la performance et de la charge de travail de l'opérateur.Les résultats de ces différentes études conduisent à proposer une démarche de conception d'un système sociotechnique qui reprend et enrichit le cadre du CWA (Cognitive Work Analysis) et à discuter du positionnement et de la formalisation del’allocation des fonctions dans le processus de conception des systèmes homme-­‐machine. / This thesis comes within the scope of sociotechnical systems design. It is applied to thesubmarine rudder control system. It focuses, in particular, on the stage of functions allocation between helmsman and machine.The objective of the first experiments was to test an "ecological" interface automating the function of information analysis. Two experiments evaluated its effects on performance, workload and situation awareness of helmsmen performing steering tasks.A second phase consisted in defining different proposals of dynamic allocations of functions between helmsman and machine. An experiment was carried out, in order to evaluate a solution of adaptive automation.The results of these studies lead to propose an approach for designing a socio-­‐technical system, which relies on and enhances the CWA (Cognitive Work Analysis) framework. They lead also to discuss place and formalisation of the functions allocation's stage into the process of sociotechnical systems' design.

Essa dissertação é formada por três artigos que versam sobre o Serviço de Atendimento Móvel de Urgência – SAMU, da Região Metropolitana de Porto Alegre. O primeiro artigo analisa a extensão na qual o SAMU opera como um sistema sociotécnico, considerando os 19 princípios propostos por Clegg (2000), tendo ficado claro que o sistema atende a 4, parcialmente a 3 e não atende a 12 deles. O segundo artigo foca o sistema de regulação do SAMU à luz dos quatro subsistemas do sistema sociotécnico: o pessoal, do projeto de trabalho, o tecnológico e do ambiente externo. O método utilizado para análise foi a Análise Macroergonômica do Trabalho – AMT (GUIMARÃES, 2010), que viabilizou a identificação de demanda ergonômica dos envolvidos no sistema, a partir de entrevistas e/ou questionários com 118 pessoas, sendo 41 trabalhadores da regulação e 77 das bases.Os resultados mostraram que os ítens de maior impacto para o desenvolvimento do serviço advém do ambiente externo, principalmente o despreparo da população para o uso do serviço (os trotes chegam a 69% das chamadas) e o risco de omissão de socorro. O terceiro artigo avalia o SAMU como um sistema complexo sob a ótica da Engenharia de Sistemas Cognitivos (ESC), que considera os fatores de coordenação, resiliência e “affordance” que emergem nas interações entre tecnologia e pessoas que compõem um sistema de trabalho. Concluiu-se que o SAMU possui diversas características de um sistema sociotécnico complexo, e que o sistema é descoordenado e clumssy, pois não possui artefatos e procedimentos de trabalho que agilizem o processo de trabalho. As características de resiliência são pró ativas e emergentes, pois os agentes diretos estão em constante adaptação para contornar os obstáculos encontrados no sistema de trabalho. Foram feitas algumas sugestões para melhoria do serviço, que poderão ser efetivadas a longo prazo, tendo em vista as dificuldades impostas pelo ambiente externo (legislação e questões políticas e sócio-culturais). / This dissertation consists of three articles that focus on the Mobile Emergency Service – SAMU of the Metropolitan Region of Porto Alegre. The first article examines the extent to which the SAMU operates as a sociotechnical system, considering the 19 principles proposed by Clegg (2000), it was clear that the system meets the 4, 3 and partially does not meet 12 of them. The second article focuses on the system of regulation of SAMU in the light of the four subsystems of the socio-technical system: staffing, project work, the technological and the external environment. The method of analysis was the Macroergonomic Work Analysis - MWA (GUIMARÃES, 2010), which enabled the identification of ergonomic demands of those involved in the system, based on interviews and / or questionnaires to 118 people, including 41 employees of regulation and 77 bases. The results showed that the items of greatest impact on service development comes from the external environment, especially the unpreparedness of the population using the service (hazing reach 69% of calls) and the risk of failure to save. The third article assesses the SAMU as a complex system from the perspective of Cognitive Systems Engineering (CSE), which considers the factors of coordination, resilience and "affordance" that emerge in the interactions between technology and people that make a system work. It was concluded that the SAMU has several characteristics of a complex socio-technical system and the system is patchy and clumssy as it has no artifacts and work processes that streamline the work process. The characteristics of resilience are clear, as the direct agents are constantly adapting to bypass the obstacles encountered in the work. There have been some suggestions for improving the service, which could take effect in the long term, in view of the difficulties imposed by the external environment (legislation and policy issues and socio-cultural).

O Serviço de Atendimento Móvel de Urgência (SAMU) é o responsável pelo atendimento préhospitalar (APH) realizado no Brasil que é aquele que se desloca para atender as vítimas em casos de urgência-emergência, funciona através de uma rede telefônica e pode ser caracterizado como um sistema complexo por envolver as centrais de regulação e as bases com as ambulâncias. Essa dissertação é formada por dois artigos que versam sobre o SAMU. No primeiro deles o objetivo foi mapear as influências do ambiente externo do SAMU metropolitano de Porto Alegre sob a ótica dos sistemas sociotécnicos. Para tal foi utilizada a análise macroergonômica do trabalho – AMT (GUIMARÃES, 2010) que tornou possível o entendimento da influência do ambiente externo no atendimento da população. Foi destacada na pesquisa a falta de conhecimento da população quanto ao funcionamento do SAMU, o elevado número de trotes, a falta de integração entre os serviços públicos, entre outros. Além disso, dentro da macroergonomia, a percepção dos fatores de riscos a que estão submetidos os trabalhadores é fundamental para que durante o atendimento realizado à população não haja dúvida quanto aos procedimentos seguros a serem adotados, para se evitar que possa ocorrer algum acidente. No segundo artigo foi realizada uma pesquisa identificando a percepção dos trabalhadores quanto aos fatores de risco. Identificou-se que os fatores de riscos como levantamento de peso, esforço físico intenso, calor e contaminação biológica por fluidos corpóreos dos pacientes foram os mais significativos na percepção dos trabalhadores do SAMU. / The Mobile Emergency Service (SAMU) is the responsible for the Emergency Medical Services (EMS) in Brazil. The EMS system is that move to take care of the victims in urgencyemergency cases, it works through a telephonic net and can be characterized by a complex system that involving the central offices of regulation and the bases with the ambulances. This dissertation consists of two articles that focus on the SAMU. In the first article, the objective of the study was to analyze the influences of the external environment of the SAMU of the Metropolitan Region of Porto Alegre under the optics of the sociotechnical systems. In this study the method of analysis was the Macroergonomic Work Analysis – MWA (GUIMARÂES, 2010) that it made possible to understand the influence of the external environment in the attendance of the population. It was identified in the research: the lack of knowledge of the population on the functioning of the SAMU, the raised number of hoax, the lack of integration between the public services, among others. Besides, in the macroergonomics, the perception of the hazards for the workers is fundamental. Since during the emergency medical service for the population it must not have doubt on the safe procedures to be adopted, to prevent that some accident can occur. Therefore in the second article, a research was carried out to identify the perception of the workers on the hazards. It was identified that the hazards as weight lift, intense physical effort, heat and biological contamination for corporeal fluids of the patients had been those most significant in the perception of the workers of the SAMU.

A tese tem como foco central a configuração que assume a rede sociotécnica do babaçu no Bico do Papagaio – TO, construída pela associação de seres humanos e não humanos e a interface que estes estabelecem com as estratégias de reprodução social e as relações sociedade-natureza. O que se busca destacar na pesquisa são as formas de reprodução social do agroextrativismo do babaçu como produto dessa rede sociotécnica e as dinâmicas atuais das relações sociedade-natureza decorrentes dessas estratégias. Como ponto de partida foram formuladas três questões de pesquisa: a primeira, direcionada à identificação e análise dos elementos (sociais, políticos e naturais) convergentes e/ou divergentes que têm afetado o extrativismo do babaçu; a segunda, no entendimento da interação dos diferentes atores na formação dessa rede; e a terceira, na busca dos desdobramentos dessa interação na reprodução social das famílias agroextrativistas do babaçu e nas dinâmicas das relações sociedade-natureza. A pesquisa de campo foi realizada no segundo semestre de 2009 e no primeiro semestre de 2010, na qual se adotou como referencial teórico-metodológico a Teoria do Ator-Rede (ANT), que parte do pressuposto epistemológico da necessidade de rompimento da dicotomia sociedade-natureza. Após análise dos dados primários levantados por meio de uma pesquisa etnográfica concluiu-se que as mudanças e permanências sofridas no contexto da região do Bico do Papagaio, que as estratégias de reprodução social adotadas pelos agroextrativistas, têm produzido efeitos transformadores, em vários níveis e intensidades, nas dinâmicas de relações sociedade-natureza no sentido de serem produtoras de resultados menos nocivos ao ambiente. Por outro lado, as atividades agropecuárias (criação de gado e monocultivos) e a produção silvícola, contribuem para a produção de efeitos negativos ao ambiente natural com a diminuição da biodiversidade e a ameaça às formas de exploração agroextrativista. Conclui-se, então, que o estabelecimento da rede sociotécnica do babaçu no Bico do Papagaio - TO, iniciada com a luta pela posse da terra, pelo acesso livre e preservação do babaçu, está inteiramente atrelada a categorias culturais nucleantes, centrais para o agroextrativismo, como a terra, o babaçu, a família e o trabalho. A terra e o babaçu organizam a vida das famílias rurais do Bico do Papagaio, porém elas resignificaram a luta iniciada pelo direito à posse da terra. Atualmente, essa luta baseia-se nas mobilizações em torno do acesso livre ao babaçu, preservação da palmeira, contra a expropriação e em busca de agregação de valor ao fruto. / The central focus of this thesis is the configuration that takes the sociotechnical network of babassu in the Bico do Papagaio-TO region, constructed by the association of humans and nonhumans, and the interface they establish with the strategies of social reproduction and the relations between society and nature. This research attempts to highlight the forms of social reproduction of the babassu’s havesting as a product of this sociotechnical network and the current dynamics of the nature-society relations derived from these strategies. As a starting point, there were formulated three research questions: the first, targeted on the identification and analysis of the social, political and natural convergent and/or divergent elements that have affected the babassu’s harvesting; the second, in the understanding of the interaction of the different actors in the network formation; and the third, in the search of the implication of this interaction within the social reproduction of the families that harvest babassu palm, and in the dynamics of the nature-society relations. The field research was conducted in the second half of 2009 and the first half of 2010. Actor-Network Theory (ANT) was adopted as a theoretical and methodological reference, which assumes the need for an epistemological rupture in the nature-society dichotomy. After analyzing the primary data obtained through ethnographic research, the conclusion is that the changes and continuities occurred in the context of the Bico do Papagaio region, and the social reproductive strategies adopted by the social agroextractivists had produced transformative effects at various levels and intensities, especially in the dynamics of nature-society relations in the sense of producing less harmful results to the environment. On the other hand, agricultural activities (cattle and monocultures) and the silviculture production contribute to produce negative impacts to the natural environment by reducing the threat to the biodiversity and the ways of harvesting babassu. In conclusion, the establishment of the sociotechnical network of babassu in Bico do Papagaio-TO, which began with the fight over land ownership, access and preservation of babassu palm, is entirely tied to cultural nuclear categories key to the extractivism such as land, babassu palm, family and work. The land and babassu palms organize the lives of rural families in Bico do Pagagaio, but they reframe the fight over the right to land ownership. Currently, this fight is based on the mobilizations around the free access to babassu palm coconut, preservation of its palm, and against expropriation and the search of adding value to the fruit.

Les "déchets" organiques sont utilisés pour fertiliser les terres agricoles depuis l’avènement de l’agriculture. Longtemps considérés comme des ressources, les résidus organiques urbains ne deviennent des déchets qu’au début du 20ème siècle. Ils sont alors délaissés par le monde agricole et entassés dans des décharges. Aujourd’hui leur valorisation s’impose comme un des axes majeurs des politiques de gestion des déchets. En parallèle, l’agriculture cherche les voies d’une augmentation de la production qui soit respectueuse de l’environnement. A la croisée de ces deux problématiques, le programme de recherche ANR "ISARD", qui constitue à la fois le cadre et l’objet de cette étude, vise à une "Intensification écologique des Systèmes Agricoles par le Recyclage des Déchets". Différents "produits résiduaires organiques" sont ainsi appelés à devenir de véritables intrants agricoles, sûrs et efficaces, participant à l’intensification de l’agriculture. Leur intégration dans des dispositifs industriels de normalisation, leur conférant le statut de produit commercial, apparaît comme le moyen le plus adapté pour répondre à ces attentes. En suivant les enseignements des sociologies pragmatistes prenant en compte le rôle des objets dans l’action, c’est à la description des différentes formes sociotechniques de la valorisation agricole (ressource, déchet, produit) que se consacre ce travail. La prise en compte d’une pluralité de formes de valorisation permet d’insister sur les déplacements induits par une logique "produit" et les reconfigurations qu’elle provoque, notamment par rapport à la pluralité des mondes agricoles. / Organic "waste" has been used to fertilize agricultural land since the very beginning of agriculture. Urban organic residue, which has been considered a resource for a long time, only became a real "waste" at the beginning of 20th century, being then abandoned by farmers and packed into dumps. Today, after its reduction, its valorisation is becoming a major goal of waste management public policies. At the same time, the agricultural world is trying to reach an increased production with less environmental impact. Poised between these two issues, the ISARD research program, which is both the subject and the framework of this study, aims at an "ecological intensification of agricultural production systems through waste recycling". As a consequence, various "residual" organic matters are destined to become safe and efficient agricultural inputs, taking part of the agricultural intensification by strengthening the fertilization ecosystem services naturally provided by soils. Their integration in normalized industrial systems, making them real commercial products, seems to be the best way to come up to these expectations. This work devotes itself to describe the various socio-technical forms of agricultural valorisation (resource, waste, product), following the teachings of pragmatist sociologists by taking the role of objects in action into account. The plurality of valorisation forms allows this study to lay stress on the changes brought by a "product" approach and the related social reconfiguration possibly conflicting with a number of agricultural worlds.

abstract: This dissertation explores the contemporary politics of global transformation: the ways biological expertise and economic rationalities are positioned as agents of governance in the face of emerging global crisis. It examines visions for a new bioeconomy that are offered in response to impending global crisis. Leaders point to calculations of global population growth and resource depletion to predict future crises and call for a new bioeconomy as a pillar of sustainable and “good” governance. Focusing on visions and practices of bioeconomy-making in the U.S. and Brazil, the dissertation examines bioeconomy discourse as a response to global crisis and a framework of global governance that promises resource abundance and human wellbeing. Bioeconomy discourse makes visible shared notions of how the world is and how it should be that animate the world-making practices of bioeconomy. The dissertation analyzes the bioeconomy as simultaneously a product of existing institutional and nationally situated values and rationalities, and a significant site of performative novelty. It is an effort to reformulate existing projects in the biosciences—from technology regulation to market formation—and establish new rationalities of governance in the name of producing thoroughgoing transformations to both the global economy and to life itself. Framing existing scientific and economic rationalities as suppressed and misdirected in their power to govern, bioeconomy proponents envision a novel order derivable from the proper conjugation of biological and economic rationalities. Through the lens of bioconstitutionalism, the dissertation elucidates how national, scientific and public rights and responsibilities are coproduced in relation to a sociotechnical imaginary of vital conjuring. Underwritten by the imaginary of vital conjuring, visions of a future transformed promise that abundance and order can be called up from a tangle of crisis and decay. The imaginary of vital conjuring marries a vision of the technological potential of biological life and the forms of economy capable of unlocking that potential. This vision of bioeconomy, the dissertation argues, is a vision of governance: of the right relationships between state, citizen and science. / Dissertation/Thesis / Doctoral Dissertation Human and Social Dimensions of Science and Technology 2020

Infrastructure continues to perpetuate the effects of splintering urbanism in South African cities. Where apartheid planning policies such as the group areas act used infrastructure as a mechanism of social organisation, this design dissertation proposes using architecture as social infrastructure to transcend these sociotechnical divides. The concept of the sociotechnical denotes the synergy of a city's infrastructural systems and its social life. In this design dissertation this idea is explored at various scales: at the urban level, through a development strategy that spatialises unsafe public open land; at the architectural scale, through surface articulation and interfacing with urban infrastructure; and at the technical level, through building performance analysis and technical design development in support of architectural goals. The project uses a distributed programme that stretches across communities in order to socialise the existing urban infrastructure of a pedestrian bridge. By leveraging the social significance of a local football club, the project proposes a social programme around the idea of a football clubhouse as a programmatic anchor. In reacting to urban infrastructure, the idea of imageability and presence are important considerations. These concepts enable youth to positively engage with the architecture, and allows the building to convey its purpose and programmatic intent, thereby creating a strong social interface with its users. Sociotechnical architecture is considered as an urban armature that socialises and spatialises urban infrastructure. The architecture therefore seeks the minimal amount of fixity to support a variety of flexible events surrounding sports and recreation activities. This is achieved through a selection of robust materials used in horizontal surfaces of social purpose, and the combination of structure, materiality and geometry to create a series of vertical surfaces of social presence and architectural imageability. The result is a strategic arrangement of architectural interventions deployed across a large urban scheme. By distributing the architecture across urban infrastructure, the project connects two communities and presents an architectural response to splintering urbanism.

Developing complex sociotechnical systems often involves integrating new technology into existing systems by applying systems engineering processes. This requires an understanding of the problem space and the possible impact of the new technology. Systems engineering uses modelling to explore the structural, functional, and operational elements of the problem and solution space (Hitchins 2008). Historically, systems engineering has however struggled with complex sociotechnical systems projects, as it cannot cope with the dynamic behaviour of complex sociotechnical systems. The hypothesis of this thesis is that addressing the contribution of humans performing work in a complex, constrained and dynamic environment using modelling will result in a better understanding in the analysis phase; it should also lead to improved requirements, designs, selection of technologies, and implementation strategies, enabling sociotechnical systems to cope with complex operating environments. A sociotechnical system consists of humans applying technology to perform work through processes within a social structure (organisation) aimed at achieving a defined objective (Bostrom & Heinen 1977, Walker et al. 2009). Work can become complex due to non-linear and dynamic interaction among the people themselves, among people and technology, as well as among people and the environment. Complexity may lead to “wicked and messy” problems, as many unintended or unpredicted consequences may be experienced. The new technology may also lead to new task possibilities that evolve user requirements (Carroll & Rosson 1992). Systems engineering, as developed in the 1950s, forms the basis of developing systems, including sociotechnical systems. Classic systems engineering processes assume that problems can be isolated and decomposed, making the development of complex sociotechnical systems difficult. One way to improve the success of systems engineering is to ensure that the problem to be solved is properly understood. Analysis of the problem and solution space involves capturing and modelling the knowledge and mental models of the stakeholders, to support understanding the system’s requirements. A good description of the problem situation through a model is the first step towards designing and developing a solution. The aim of this study is to develop and demonstrate a modelling methodology for complex sociotechnical systems, in support of the systems engineering process. The two approaches used in the modelling methodology are cognitive work analysis and system dynamics. Cognitive work analysis is a framework for analysing the way people perform work in an organisation, while taking the environmental constraints into consideration. The outputs of cognitive work analysis are constructs or models that capture the structure of the problem. Functions provided by different technological elements are linked to the functional requirements of the system, to achieve its purpose (Lintern 2012). However, cognitive work analysis is limited in investigating the dynamic effect of decisions and policies on the system (Cummings 2006). The dynamic behaviour of complex sociotechnical systems can be analysed using system dynamics, which uses the structure of the system in simulation. System dynamics analyse the effect of feedback and delays on operating the system, as a result of decisions based on policies (Sterman 2000). The design science research framework, which also supports the research design of this thesis, is used to implement the modelling and structure the methodology. Design science research aims at creating technology for a human purpose, unlike the natural sciences, which are geared towards attempting to understand and define reality (March & Smith 1995). The proposed methodology is demonstrated in a case study using modelling and analysis of the impact of a new collaboration technology on command and control systems. Command and control is a good example of a complex sociotechnical system, as humans use technology to assemble and analyse information for situation assessment in support of planning operations (Walker et al. 2009). These systems are also used to control the successful implementation of plans in constrained and variable operating environments. The modelling methodology is demonstrated by modelling and assessing the effect of a new command and control technology for border safeguarding operations, anti-poaching operations and community policing forums. The new technology to be implemented in these complex sociotechnical systems is called “Cmore”. It is a web-based collaboration system that uses smartphones to capture information and track users. Even though the three demonstrations constitute similar systems, the different contextual situations result in diverse behaviour and issues to be investigated. The demonstrations centre on the functions of situation awareness and decision support. The different output models for the command and control systems are used in system dynamics simulations to assess the effect of new technology on the operating and effectiveness of a system. The case studies demonstrated that the modelling methodology support learning about the implementation of a new technology in various complex sociotechnical systems. The developed models and constructs also supported developing evaluation templates during the planning of experiments through identifying key issues. The system dynamics simulations used parametric inputs to investigate the behaviour of the system. In most cases, the simulation outputs identified interesting and counter-intuitive behaviour for deeper assessment. The community policing forum case study also gathered qualitative empirical evidence on the system's behaviour, during a field experiment. The outcomes are compared with the models and simulation outputs to improve the system behavioural models. The learning and improved understanding of the complex sociotechnical system behaviour gained through the modelling methodology, demonstrated its utility. / Thesis (PhD)--University of Pretoria, 2014. / tm2015 / Graduate School of Technology Management (GSTM) / PhD / Unrestricted
