There are many contributing factors that influence the development, deployment, and use of lean manufacturing techniques. This study will focus on an automotive factory production system but will gather data across many areas. The concepts presented in the available research will then be related to lean manufacturing techniques at a union-based automotive factory. Several factors to focus on during this study are the Industry 4.0 movement, production systems, deployment and implementation strategies, lean manufacturing, persuasive technology, and manufacturing culture. These factors play a significant role in developing and implementing core techniques, which would lead to best in class metrics. The study will also experiment with different technologies and apply these finding to an assembly line. Two contributions that this research will add to the body of knowledge: 1. An action research deployment of instant feedback stations at operators’ workstations with results and analysis of quality outputs. 2. An action research deployment of instant feedback production check sheets from operators to management with results and analysis of quality outputs.

Rapid urbanization and limited resources is creating enormous challenges to cities in the global South, which has been increasingly acknowledged as a motivation for international cooperation in recent years. Both theory and practice have however paid little attention to how differences in geographical contexts and views on what sustainability is play out in such cooperation. This study therefore explores how Swedish actors have sought to contribute to urban sustainability in low-income countries in the Global South. These efforts are traced through a case study of the Swedish SymbioCity concept by using an actor-network theory approach. Policy mobility theory is used to discuss how the transfer and translation of policies between cities takes focus away from their contested nature. Concepts are then drawn from socio-technical transitions theory to discuss what this specifically means in transitioning towards sustainability. Data is gathered through review of written materials and semi-structured interviews with actors in the case study. In following the evolution of the Sustainable City concept, I argue that it has managed to mutate so well “from trade to aid” due to its “fluid” and lovable qualities and a notion of Swedish urban sustainability which can be flexibly interpreted. In tracing the networking of Swedish sustainability, I argue that SymbioCity has followed a previously observed pattern in which the approach has been adapted to travel and the recipients have been prepared to receive the approach. In considering how the approach has impacted its recipients, I argue that although its applications seem to have been appreciated, the translation of urban sustainability throughout the network has turned focus away from the issue of what urban sustainability is by coordinating activities and by educating the recipients’ attention towards techno-managerial problem framings. I conclude that Swedish actors have managed to carefully adopt a commercial model of urban sustainability to the purposes of development cooperation and its geographical contexts of application. While this mutation has given rise to a network of somewhat disconnected practices, the efforts of both branches have nevertheless contributed to establishing sustainability as being fundamentally uncontested in its nature. This view of sustainability can be said to be permitted by certain interpretations of the Swedish experience of becoming more sustainable. From this I conclude that to ensure that international cooperation for urban sustainability takes place on equal and fundamentally democratic terms, Swedish actors (and sustainability transition theorists alike) would do well to also encourage and facilitate inclusive and critical discussions of how urban sustainability can be understood, in the North as well as the South. The main limitation of this work lies in the actual engagement with the targeted cities, which prevents a thorough understanding of both the perceived and the actual impact of the export of Swedish urban sustainability. Further research should therefore pay attention to how it has affected the targeted cities.

The need for a more sustainable approach to water consumption has increasingly gained attention in the last decade. The domestic sector accounts for over half of abstracted water in the UK and, as such, has become a major target for water efficiency interventions. Current research and water efficiency interventions are dominated by a positivist approach, focusing on a limited range of factors that can be quantitatively measured. This thesis questions the dominant approach and argues that a more holistic overview of water efficiency can be achieved through the consideration of socio-technical and behavioural theories. Taking a more constructivist approach, this research draws on four theories from socio-technical and behavioural fields and combines them to create a framework for the analysis of water efficiency interventions. The framework is applied to two case studies, exploring water users¿ perceptions of water, water supply, personal water use, and their responses to the water efficiency interventions. The case studies were selected to provide examples of current mainstream approaches to water demand management. Research methods used included semi-structured interviews and observation. The research findings support the argument that the current dominant approach to domestic water efficiency interventions is limited and, in some cases, ineffectual. Issues of trust, knowledge, motivation and the relationships between water users and water companies were raised. The thesis concludes that the use of a constructivist perspective could help to provide a more effective approach to understanding and improving water demand management.

Brazil is one of the largest economies in the Global South. Because of the country’s strong agribusiness and large population, it has a huge potential for biogas production that has yet to be realized. Biogas systems could potentially address a broad range of social, environmental, and economic issues, such as improving accessibility to clean energy sources in rural areas, alternative cooking fuel, and providing proper treatment of organic waste. Hence, biogas systems can play an important role in sustainability transitions by improving the environmental performance of energy generation, waste management systems, and food production. However, despite the availability of substrate for biogas production and the multiple benefits that biogas systems could bring, there is still a large implementation gap.   Biogas systems go beyond technical components and involve a multitude of stakeholders, infrastructure, knowledge, and formal and informal institutions. Therefore, the diffusion of biogas systems cannot be explained only by analyzing the technical components of biogas systems. Previous studies have explored the influences of societal contexts on technological diffusion, but these explored countries in the Global North. However, social, economic, and political aspects differ significantly between Global North and Global South countries.   This thesis aims to explain how societal contexts influence the diffusion of biogas systems in Brazil. The thesis distinguishes between societal contexts, delineating them as societal environments and socio-economic structures. Societal environments refer to the circumstances and aspects surrounding the diffusion process where alignment processes between new socio-technical systems and society happen across five environments: user, business, regulatory, cultural, and trans-local. Socio-economic structures refer to societal arrangements that shape social and economic aspects of society. The Varieties of Capitalism framework provides a tool for comparison of the socio-economic structures of different countries in the Global North and South. The thesis relies on case studies based on quantitative and qualitative data from documents (scientific articles, news articles, technical reports, research reports, official documents by governmental agencies, and policies) and interviews.    Societal contexts appear to be more unstable and fragmented compared to counterparts in the Global North, influencing the diffusion of biogas systems. Hierarchical structures in Brazil lead to power disparities between administrative levels (municipal, state, and federal levels), impacting policymaking and hindering local-level biogas system configurations. The thesis highlights socio-economic diversity among Brazilian states and how it influences where and which biogas system configurations are formed. This thesis emphasizes that studies on biogas systems’ potential should consider contextual aspects beyond substrate availability to comprehensively understand biogas systems diffusion in diverse settings. / Brasilien är en av de största ekonomierna i den globala södern. Givet landets starka jordbruksindustri och stora befolkning finns goda förutsättningar för storskalig biogasproduktion. Men det är en potential som ännu inte har exploaterats i någon större utsträckning. Biogassystem har potential att bidra till lösningen på flertalet sociala, miljömässiga och ekonomiska frågor, såsom att förbättra tillgången till rena energikällor på landsbygden, erbjuda alternativa bränslen för matlagning och att tillhandahålla lämplig behandling av organiskt avfall. Därmed kan biogassystem spela en viktig roll i en hållbar omställning genom att förbättra miljöprestandan för energiproduktion, avfallshantering och livsmedelsproduktion. Trots de många fördelarna som biogassystem medför finns alltså fortfarande en stor klyfta mellan potentialen och vad som är realiserat.   Biogassystem sträcker sig bortom tekniska komponenter och inkluderar även en mångfald av intressenter, infrastruktur, kunskap samt formella och informella institutioner. Därför kan spridningen av biogassystem inte förstås enbart genom att analysera tekniska komponenter i biogassystemet. Tidigare studier som har studerat hur sådana bredare samhällsfaktorer påverkar spridningen av teknologi har huvudsakligen undersökt länder i västvärlden (det globala norr). Men sociala, ekonomiska och politiska aspekter skiljer sig betydligt mellan länder i det globala norr och det globala söder.   Denna avhandling syftar därför till att förklara hur olika samhällsfaktorer påverkar spridningen av biogassystem i Brasilien. Avhandlingen skiljer mellan olika sorters samhällsfaktorer och delar in dem i samhälleliga miljöer och socioekonomiska strukturer. Samhälleliga miljöer avser de omständigheter och aspekter som omger spridningsprocessen där anpassningsprocesser mellan nya sociotekniska system och samhället sker över fem miljöer: användarmiljön, affärsmiljön, den reglerande miljön, den kulturella miljön och den translokala miljön. Socioekonomiska strukturer avser samhälleliga arrangemang som formar sociala och ekonomiska aspekter av samhället. För att jämföra socioekonomiska strukturer i olika länder i det globala norr och globala söder används även ramverket ”Varieties of Capitalsim” som beskriver olika former av kapitalism. Avhandlingen baseras på fallstudier och använder kvantitativa och kvalitativa data från dokument (vetenskapliga artiklar, nyhetsartiklar, tekniska rapporter, forskningsrapporter, officiella dokument från statliga organ och policys) samt intervjuer. Resultaten visar att de studerade samhällsfaktorerna i Brasilien verkar vara mer instabila och fragmenterade jämfört med motsvarigheter i det globala norr, vilket påverkar spridningen av biogassystem negativt. Hierarkiska strukturer i Brasilien leder till maktobalans mellan administrativa nivåer (kommunal, delstatlig och federal nivå), vilket påverkar politiskt beslutsfattande och hindrar utvecklingen av biogassystem på lokal nivå. Avhandlingen lyfter fram betydelsen av socioekonomisk mångfald bland Brasiliens delstater och hur dessa påverkar var och vilka biogassystem som utvecklas. Avhandlingen understryker att studier om biogassystems potential bör överväga kontextuella aspekter bortom tillgång på substrat för att bättre förstå spridningen av biogassystem i olika sammanhang. / <p><strong>Funding:</strong> the Biogas Solutions Research Center (BSRC)</p>

There is an emerging market of radical eco-innovations that require high involvement from the U.S. consumer for successful routinization. Yet, there exists a gap in knowledge that guides the dissemination of such innovations for related stakeholders. Among these innovations is the household digester (HD), which is marketed as an innovation capable of generating biogas and fertilizer through processing organic waste at its point-of-source (POS). The HD may surpass other high-involvement eco-innovations in respect to levels of involvement necessary for consumer routinization and sustained operation. However, previously unexplored factors within the contemporary U.S. landscape have spurred recent growth in HD adoption. This dissertation took a three-manuscript approach in the investigation of factors that influence the adoption and diffusion of HD in the U.S. The first of three studies tested a literature-based conceptual model framed within the multi-level perspective (MLP) to identify barriers and drivers of HD adoption. Qualitative data from expert interviews and social media posts inform the production of a taxonomy of complexities that depict the current state of HD in the U.S. Findings indicate that HD marketing during the Covid pandemic brought forth new adopter populations seeking resilience due to infrastructure distrust. The second study investigated motivations for HD adoption through operationalizing constructs from psychology literature and diffusion of innovation theory (DOI). Through in-depth interviews with adopters, the factors of relative advantage, compatibility, and cost were found to outweigh pro-environmental behavior (PEB) in adoption decisions. Furthermore, high-involvement was not found to influence adoption decisions. The final study employed a collective case study approach that explored paths to HD routinization among ten adopters. Results highlight the ability of adopters to overcome technical challenges through reinventions necessary for contextual adaptations. This dissertation contributes insights into the adoption and diffusion of radical high-involvement eco-innovations, offering implications for policy, practice, and future research in emerging innovations interacting within socio-technical transitions. / Doctor of Philosophy / A variety of emerging products are entering the U.S. consumer market that promote household sustainability, many of which require high levels of involvement from consumers for successful adoption. These high-involvement eco-innovations have been studied within the context of electric cars, organic foods, and other products that require extensive consumer research before purchase. However, this research focuses on a new product entering the U.S. market where involvement not only requires extensive pre-purchase research but also radical levels of interaction during operation and maintenance for successful product use. The household anaerobic digester is an apparatus that turns organic waste into cooking fuel and fertilizer. This innovation has been widely adopted in the developing world with some success, but technical issues during operation have been shown to result in discontinued use. This dissertation focuses on the adoption of household digesters in the U.S. Radical high-involvement eco-innovations need further scientific analysis to understand what factors might affect adoption, as well as explore the viability of such products entering a market where convenience is a social norm. This research aims to provide an analysis of this phenomenon through three studies. Chapter Two explores this new product and factors that may hinder or accelerate adoption in the U.S. Experts in the field of household digesters are interviewed for data collection, as well as analysis of social media posts where new adopters share information. This study aims to determine the social and technical complexities of Americans adopting household digesters. The Third Chapter assesses the purchase motivations of current adopters of household digesters in the U.S. This assessment takes place through interviews, where consumers provide information about their traits, values, and the degree to which they use the product to replace an existing technology. Chapter Four takes a further look at adopters to gain an understanding of paths to adoption and commonly shared practices that are employed to be successful in the adoption of household digesters. This study first presents the stories of each adopter and then provides a cross-case analysis that reveals commonalities of adopters regarding how paths to adoption often lead to shared practices for successful HD operation. The work is summarized in Chapter Five with conclusions, lessons learned, and recommendations for future research. This includes drawing connections between the three studies' findings and how the studies' chronology brought forth validation in the instruments used for data collection.

Socially coupled systems are comprised of inter-dependent social, organizational, economic, infrastructure and physical networks. Today's urban regions serve as an excellent example of such systems. People and institutions confront the implications of the increasing scale of information becoming available due to a combination of advances in pervasive computing, data acquisition systems as well as high performance computing. Integrated modeling and decision making environments are necessary to support planning, analysis and counter factual experiments to study these complex systems. Here, we describe SIMFRASTRUCTURE -- a computational infrastructure that supports high performance computing oriented decision and analytics environments to study socially coupled systems. Simfrastructure provides a middleware with multiplexing mechanism by which modeling environments with simple and intuitive user-interfaces can be plugged in as front-end systems, and high-end computing resources -- such as clusters, grids and clouds -- can be plugged in as back-end systems for execution. This makes several key aspects of simulation systems such as the computational complexity, data management and resource management and allocation completely transparent to the users. The decoupling of user interfaces, data repository and computational resources from simulation execution allows users to run simulations and access the results asynchronously and enables them to add new datasets and simulation models dynamically.  Simfrastructure enables implementation of a simple yet powerful modeling environment with built-in analytics-as-aservice platform, which provides seamless access to high end computational resources, through an intuitive interface for studying socially coupled systems. We illustrate the applicability of Simfrastructure in the context of an integrated modeling environment to study public health epidemiology and network science. / Master of Science

Modern complex safety-critical socio-technical systems (STSs) operate in an environment that requires high levels of human-machine interaction. Given the potential for catastrophic events , understanding human errors is a critical research area spanning disciplines such as management science, cognitive engineering, resilience engineering, and systems theory. However, a research gap remains when researching how errors impact system performance from a systemic perspective. This dissertation employs a systematic methodology and develops models that explore the relationship between errors and system performance, considering both macro-organizational and micro-worker perspectives. In Essay 1, the focus is on how firms respond to serious errors (catastrophic events), by exploring the oscillation behavior associated with the organizational learning and forgetting theory. The proposed simulation model contributes to the organizational science literature with a comprehensive approach that assesses the firm's response time to "serious" errors when the firm has a focus on safety with established safety thresholds. All of these considerations have subsequent impact on future performance. Essay 2 explores the relationship between safety-critical system's workers' workload, human error, and automation reliance for the Belgian railway traffic control center. Key findings include a positive relationship between traffic controller performance and workload, and an inverted U-shaped relationship with automation usage. This research offers new insights into the effects of cognitive workload and automation reliance in safety-critical STSs. Essay 3 introduces a calibrated System Dynamics model, informed by empirical data and existing theories on workload suboptimality. This essay contributes to the managerial understanding of workload management, particularly the feedback mechanism between operators' workload and human errors, which is driven by overload and underload thresholds. The model serves as a practical tool for managerial practitioners to estimate the likelihood of human errors based on workload distributions. Overall, this dissertation presents an interdisciplinary and pragmatic approach, blending theoretical and empirical methodologies. Its broad impacts extend across management science, cognitive engineering, and resilience engineering, contributing significantly to the understanding and management of safety-critical socio-technical systems. / Doctor of Philosophy / This dissertation is motivated by the increasing autonomy in infrastructure systems designed to enhance safety performance. Yet paradoxically, we continue to witness system failures leading to catastrophic disasters. High-profile incidents such as the Metro-North train derailment in New York City, the Boeing 737 MAX plane crashes, and the Challenger and Columbia space shuttle accidents highlight this contradiction. This research delves into safety-critical systems where the intricate collaboration between humans and machines is crucial, and where even minor human errors can lead to disastrous consequences. This dissertation is presented in three parts. In the first part I examine how firms react to serious errors. The study focuses on their learning processes following safety incidents and the potential for these lessons to be forgotten over time. I introduced a simulation model grounded in the organizational science literature, offering deeper insights into how companies respond to errors, including changes in safety focus, safety culture, and policy, and the impact of these factors on future company's performance. The second part shifts to a worker-centered perspective, exploring the relationship between workload, performance, and automation usage among traffic controllers. The findings indicate that while performance can improve with an increase in workload up to a certain threshold, excessive reliance on automation may lead to a decline in performance. This part of the study sheds light on how cognitive workload and technology usage influence operators in safety-critical roles. The final part of the dissertation presents another simulation model, this time focusing on how workload, and the resulting stress and boredom due to workload, influence the likelihood of errors. Utilizing real operational data from the Belgian railway transportation system, this model aids managers in understanding how to optimally balance workloads to minimize error risks. Overall, this dissertation takes an interdisciplinary and pragmatic approach, merging theoretical concepts with empirical data. Its extensive impact spans management science, cognitive engineering, and resilience engineering, significantly enhancing our comprehension and management of safety-critical socio-technical systems.

Transitions to more sustainable technologies and processes are a largely discussed topic that concerns several, if not all, global industries. This thesis studies the novel technology of electric passenger aviation as a sustainable option in the aviation industry. The study examines the prospects of electric passenger planes in Sweden specifically and is based on the perspective of established actors within the Swedish aviation industry. As such, the results of the study revolves partly around the technological capabilities of electric planes, and partly around the economical, social and political aspects necessary to make electric planes commercially viable. To assist in examining these diverse aspects, the thesis evaluates the technology from the viewpoint of a socio-technical system, using the theoretical framework of the multi-level perspective to guide the study. The results have found that electric passenger planes are likely to be introduced into the Swedish aviation market in the coming years. However, their long term success is not guaranteed and depends on multiple factors. Key challenges include: the development of battery technology, financial viability compared to alternative sustainable travel solutions, and consumers willingness to change travel habits. These challenges come as a consequence of the relatively short flight range of electric aircrafts, which in turn is due to the low energy density of the batteries being used. / Hållbarhet är ett koncept som diskuteras allt mer frekvent kring både processer och teknologier, inom många, om inte alla globala industrier. Denna uppsats studerar den nya tekniska utvecklingen kring elektriska passagerarplan som ett hållbart alternativ inom flyindustrin.  Studien undersöker de framtida möjligheterna för elektriska passagerarplan att etablera sig på en svensk marknad och baseras på perspektiv från etablerade aktörer inom svensk flygindustri. Således fokuseras studiens resultat dels på tekniska detaljer kring elflygplan, dels på ekonomsika, sociala och politiska aspekter som krävs för att kommersialisera elektriska passagerarplan. För att undersöka dessa olika aspekter använder studien ett socio-teknsikt system perspektiv, samt tar guidning av ett teoretiskt ramverk som på engelska kallas multi-level perspective.  Resultaten från studien indikerar att elektriska passagerarplan troligen kommer att introduceras inom den svenska flygmarknaden under kommande år. Dock är deras långsiktiga framgång inte garanterad och beror på ett antal faktorer. Noterbara utmaningar som identifieras är: Utvecklingen av batteriteknik, finansiell stabilitet jämfört med andra hållbara flygalternativ, och konsumenters villighet att ändra sina flygvanor. Dessa utmaningar är kopplade till den relativt korta räckvidden elektriska flygplan besitter, vilket i sin tur beror på den långa energidensiteten hos de batterier som används.

The increase and changes in the demand for emergency care require pro-active responses from the designers and implementers of the emergency care system. The role of Emergency Care Practitioner (ECP) was introduced in England to improve the delivery of emergency care in the community. The role was evaluated using cost-benefit approach and compared with other existing emergency care roles. An analysis of the cognitive elements (situation awareness (SA) and naturalistic decision making (NDM)) of the ECP job was proposed considering the mental efforts involved. While the cost-benefit approach can justify further spending on developing the role, a cognitive approach can provide the evidence in ensuring the role is developed to fulfil its purpose. A series of studies were carried out to describe SA and NDM amongst ECPs in an ambulance service in England. A study examined decision-making process using Critical Decision Method interviews which revealed the main processes in making decision and how information was used to develop SA. Based on the findings, the subsequent studies focus on the non-clinical factors that influence SA and decision making. Data from a scoping study were used to develop a socio-technical systems framework based on existing models and frameworks. The framework was then used to guide further exploration of SA and NDM. Emergency calls that were assigned to ECPs over a period of 8 months were analysed. The analysis revealed system-related influences on the deployment of ECPs. Interviews with the ECPs enabled the identification of influences on their decision-making with respect to patient care. Goal-directed task analysis was used to identify the decision points and information requirements of the ECPs. The findings and the framework were then evaluated via a set of studies based on an ethnographic approach. Participant observations with 13 ECPs were carried out. Field notes provided further insight into the characteristics of jobs assigned to the ECPs. It was possible to map the actual information used by the ECP to their information needs. The sources of the information were classified according to system levels. A questionnaire based on factors influencing decision-making was tested with actual cases. It was found that the items in the questionnaire could reliably measure factors that influence decision-making. Overall, the studies identify factors that have direct and indirect influences on the ECP job. A coherent model for the whole emergency care systems can be developed to build safety into the care delivery process. Further development of the ECP role need to consider the support for cognitive tasks in light of the findings reported in this thesis.

Trata-se da análise das estratégias de articulação e comunicação utilizadas por jovens produtores culturais da cidade de São Paulo, de modo particular sob o ponto de vista daqueles organizados em grupos e coletivos culturais localizados em suas regiões mais periféricas. Investigou-se quais relações se estabelecem entre esses coletivos e as redes e circuitos culturais existentes na cidade de São Paulo, e qual o papel exercido pelas Tecnologias de Informação e Comunicação (TICs) nesse processo, concebidas aqui enquanto ferramentas dessa articulação, não seu fim último. O estabelecimento do recorte de ação para a pesquisa partiu da investigação de uma política pública municipal de fomento à produção cultural, desenvolvida na cidade de São Paulo desde 2004, e que vêm sendo responsável por desvelar e dar visibilidade às diferentes manifestações artísticas e culturais realizadas por esses jovens: o Programa para Valorização das Iniciativas Culturais. Dentro do conjunto de projetos suportados com recursos desse programa, optou-se pela realização de um estudo de caso específico uma iniciativa em particular: a implantação de uma agência de fomento a cultura popular, denominada Agência Popular Solano Trindade. Especial atenção foi dada ao processo de elaboração do portal na internet que a Agência lançou no final do ano de 2012, e que se propõe funcionar como plataforma tanto de informação sobre as ações da instituição, suas motivações e objetivos, como de mapeamento dos atores culturais que a integram. Desse modo, pretendeu-se oferecer subsídios para o debate sobre a dinâmica das práticas culturais que se desenvolvem nas bordas da metrópole, e analisar mais detidamente de que maneira uma rede social pode animar e ampliar o desenvolvimento de uma rede sociotécnica, e o papel assumido pelo usuário enquanto parceiro do processo de construção e circulação da informação. / These studies analise the articulation and communication strategies used by cultural young producers from the city of São Paulo, in a particular way from the point of view of those organized in cultural groups located in the outskirts of the city. The dissertation investigated which relations and connections were established between this groups and cultural networks of the city of São Paulo, and what was the role of the Information and Communications Technology (ICTs) in this process, comprehended here as tools for this articulation, not as a final objective/goal. The choice for the research was originated from the investigation of a municipal public policy of cultural production enhancement, developed in São Paulo since 2004, which is being responsible for unveiling and promote visibility to different kinds of artistic and cultural expressions held by young.: the VAI (Portuguese abbreviation for Cultural Initiatives Appreciation). Among all the projects financed by this program, a specific case study of one iniciative in particular was chosen: the establishment of a popular culture enhancing agency called Agencia Popular Solano Trindade. Special attention was given to the construction of an internet website that this Agency launched in the end of 2012, and which was designed to work not only to market the actions, motivations and objectives of the institution, but also as a mapping tool of the actors who integrate it. In this way, aimed to offer elements for the cultural practices dynamics debate which are grown in the outskirts of the Metropolis but also due considerate the ways in which a social network can enhance and expand the development of a socio-ethnic network, and the role played by the user as a partner of the building and circulation of the information.
