In the late 1990s, NASA conducted a study of the Interplanetary Internet (IPN) architecture. In order to build and deploy IPN infrastructure, the network technology had to be able to cope with long radio signal propagation delays and frequent radio link disruptions. The concept of a Delay Tolerant Networking (DTN) emerged after recognizing that such a networking paradigm can also be applicable for terrestrial use. DTN technology can be applied, for instance, in disaster situations, military battlefields, economically developing areas, and remote regions.This thesis follows the process of applying DTN technology to a remote, communication-challenged area in the Arctic part of Sweden. The aim of the DTN deployments in the remote villages of Sarek and Padjelanta National Parks, between 2008 and 2011, was to provide a basic set of ICT services to the nomadic Sami population. Therefore, the research presented here acknowledges and considers the specific geographical, technical, and cultural conditions of these areas, and how these conditions profoundly shaped the development of the deployed technology as well as the research methodology. As a result, this thesis makes scientific contributions to several research topics, spanning the fields of DTN routing, DTN service development, DTN evaluation methodologies, and ICT deployments.The first contribution in this thesis is the proposal of a new and improved version of the PRoPHETv2 routing protocol. The development of this routing protocol was driven by actual protocol use and the results of experiments conducted during the course of the DTN deployments.Secondly, this thesis proposes an alternative DTN routing objective for a typical remote village DTN scenario. Weaknesses of a conventional DTN routing research objective are exposed by outlining concrete geographical, social, and technical conditions discovered in DTN deployments on the field. When these conditions are overlooked, they can profoundly affect DTN deployments.Thirdly, this thesis discusses the development and deployment of the Not-So-Instant-Messaging (NSIM) DTN service. The NSIM service was designed to leverage from the decentralized DTN infrastructure. Its success in the field demonstrates the importance of localized DTN services. Fourthly, using qualitative reading of DTN routing related papers, this thesis describes shortcomings of established DTN routing evaluation methodologies. Extensive use of simulated environments and scarce real-world experiments in the DTN research field often leads to usage of specific hypothetical scenarios. These scenarios are difficult to compare or relate to each other. Additionally, DTN research that does contextualize itself in remote, extreme, and challenging scenarios performs evaluations of proposed routing schemes in urban or academic environments. The DTN evaluation model that is proposed here tries to improve the readability, comparability, and validity of DTN routing evaluations. This thesis also pays attention to the issue of how to evaluate the complex interplay that occurs between researchers, users, technology and environment throughout the deployment process. The suggested method highlights the dynamics of resistance, as conceptualized within Actor Network Theory (ANT). It illustrates how employment of the concept of resistance facilitates the recognition of different driving forces in the design process that emerge from the events in the deployment.Ultimately, the thesis contributes with the PRoPHET routing protocol specification in the "Request for Comments" (RFC) document series that is the official publication channel for the Internet Research Task Force (IRTF) and other Internet communities. The protocol specification published as the RFC6693 document allows for actual protocol implementation and assures interoperability. The discussion that follows the RFC document in this thesis focuses on the process of transferring scientific findings gained from the experiments on the deployment field into the Internet draft document that was finally recognized as an experimental RFC within the IRTF. / Godkänd; 2014; 20140407 (samo); Nedanstående person kommer att disputera för avläggande av teknologie doktorsexamen.

Enos John Nganani Mabuza's life and work is used as a case study to highlight the conceptual and methodological theories and challenges in academic biographical writing regarding history, memory and legacies. This thesis answers the question: Who was Mabuza and what is his place or relevance in South Africa's history? We over-simplify and stereotype people because it is convenient. We judge others but there is no saint without a past or a sinner without a future. Mabuza reconciled with the main liberation movements and moved from a maligned position on the political fringes to a respectable one within the emerging black economic elite. History, like reference systems and values is not calcified or static. It is prone to interpretation, adaptation, modification, invention, manipulation, decomposition and re-composition. Bourdieu's habitus-field analysis, theory or logic of practice, notions of capital (symbolic, political, social, cultural and economic) is used together with Latour's actor-network theory as the basis of analysis of the social contracts and trust bonds that Mabuza was able to create and which enabled him to navigate South Africa's socio-political and economic milieus during apartheid and the transition in the early 1990s. As people or actors, we believe in the mantra, nothing ventured, nothing gained. We exercise agency and take risks every day. We make choices and those choices have consequences. Mabuza's choices in the fields of education, politics and business had implications for how he is perceived or has been written into history. His choices put notions of identity, citizenship, power, legitimacy, ambition, elite accommodation, class, personal and professional networks, popular struggles, agency and structure under the spotlight. Mabuza's involvement in Bantustan politics, for instance, is contextualised in terms of a historical overview of the unpopular role played by traditional authorities in South Africa before and during colonialism and apartheid. His later foray into the world of business, however, was facilitated in part, by the personal and professional contacts that he made whilst he was in politics and the opportunities which opened up during the country's political transition. Mabuza adapted to changing circumstances and demonstrated a level of versatility which other Bantustan functionaries did not or could not exercise.

Alors que les principales activités d’un chef de projet s’effectuent à travers le processus de communication, on observe que de nombreux projets font l'objet de retards, dérives ou défauts de spécifications. Excès de mesures pour prévenir le risque ou gestion déficiente de la communication laissant trop de place à l’incertitude ? La Théorie de la Réduction de l’Incertitude développée par Berger et Calabrese (1975) dans le champ de la communication ne permet pas de totalement saisir comment un chef de projet dissipe l’incertitude existante entre les acteurs. En revisitant un projet opérationnel dans le cadre d’une recherche-action, nous nous employons à identifier comment incertitude et communication s’influencent et se structurent mutuellement. Nous avons convoqué l’approche constructiviste et la théorie de l’acteur-réseau de Callon et Latour pour accéder au sens de cette relation circulaire. Nous avançons les hypothèses selon lesquelles : - L’incertitude est un actant qui intervient dans la construction du réseau (au sens de Bruno Latour (2007) « ce qui est tracé par les traductions »).- Le processus de communication diffère suivant la nature de l’incertitude rencontrée ou ressentie. - Le processus de communication performe et scelle les relations en les rendant si coûteuses à défaire et si économiques à maintenir, qu’elles deviennent irréversibles. L’approche communicationnelle de l’incertitude mettra en évidence plusieurs caractéristiques de cet actant, comme sa capacité à peupler un « réseau de manques », la façon dont le réseau se hiérarchise pour faire sens, la description du processus d’estimation continue dont il fait l’objet (l’Incertus). Si nous concevons l’incertitude comme l’attribut d’un phénomène alors la « communication-incertitude » fabrique le sens en même temps qu’elle détermine la valeur de cet attribut. En positionnant l’incertitude comme un phénomène socialement construit, nous présentons un modèle constructiviste de « communication-incertitude » où l’observateur est un acteur intentionnel limité par des contraintes (Boudon, 2009) et proposons de distinguer la nature de l’incertitude suivant une typologie : l’incertitude de variabilité (inhérente à la variabilité des choses), l’incertitude épistémique ambiguë ou non (due à l’imperfection de nos connaissances) et l’incertitude d'échelle (en rapport avec l’imperfection de nos modèles de représentations). Dans ce mouvement vers l’irréversibilité, les processus de communication participent au remplacement des médiateurs (qui transforment, redonnent du sens, font faire des choses inattendues) par des intermédiaires (qui transmettent, transfèrent sans modifier) et les actants les plus réversibles sont évacués vers la périphérie du réseau. / While the main activities of a project manager are done through the communication process, it is observed that many projects are subject to delays, excesses or defects specifications. Excess of measurements to prevent the risk ? Defective management of the communication which leaves too much place to uncertainty ? The Theory of Uncertainty Reduction developed by Berger and Calabrese (1975) in the field of communication does not fully understand how a project dissipates the existing uncertainty between actors. By revisiting an operational project within the framework of action research, we strive to identify how uncertainty and communication influence and form themselves mutually. We used the constructivist approach and the actor-network theory of Callon and Latour to reach the meaning of this circular relationship. We advance the following hypotheses: - Uncertainty is a nonhuman actor involved in the construction of the network (as defined by Bruno Latour (2007) "which is drawn by translations"). - The communication process differs according to the nature of the uncertainty encountered or felt. - The communication process performs and seals relationships by making them so expensive to undo and so economic to maintain, that they become irreversible. The communicational approach of the uncertainty will highlight several features of this nonhuman actor, as its ability to populate a "network of gaps", the way the network ranks into a hierarchy to make sense, the description of the continuous process of estimation (the Incertus). If we conceive uncertainty as an attribute of a phenomenon, then "communication-uncertainty" makes sense at the same time it determines the value of this attribute. By positioning uncertainty as a socially constructed phenomenon, we present a constructivist model of "communication-uncertainty" where the observer is an intentional actor limited by constraints (Boudon, 2009). We propose to distinguish the nature of uncertainty following a typology: the variability uncertainty (inherent variability of things), the epistemic uncertainty ambiguous or not (due to the imperfection of our knowledge) and the scale uncertainty (in touch with the imperfection of our models of representations). In this movement towards irreversibility, the communication processes involved in replacing mediators (which transform, give meaning, make unexpected things do) by intermediaries (which transmit, transfer without changing) and the most reversible nonhumans actors are evacuated to the network edge.

Abstracts in English, Afrikaans and Northern Sotho / Many individuals spend their working lives attempting to accrue financial resources to sustain them beyond their retirement. The challenge in professional sport is that a professional athlete’s career is often relatively short with various risks that could end it prematurely. In addition, there are various reasons why professional athletes find it challenging to transition to a vocational career after their sporting careers end. This highlights the importance for professional athletes to attain a high level of financial literacy from a young age. Actor-network theory (ANT) provided a suitable theoretical frame for this study by considering the information that could flow in a network around a professional athlete in pursuit of sound financial decisions. This study first developed a framework for the financial literacy skills required by professional athletes in pursuit of sustainable financial well-being. For this purpose, semi-structured face-to-face interviews were conducted with 27 interviewees. ANT was applied to guide the selection of interviewees from a network of influencers that could guide a professional athlete’s financial decisions. The results of these interviews and the open-ended responses provided the basis for the contributed framework. The second part of this multi-layered study was aimed at developing an artefact or research instrument to assess the financial literacy of professional athletes. Design science research provided the overarching research design for this qualitative study with a second round of interviews held with 10 interviewees from the list of interviewees consulted for the first part of the study. The 10 interviewees were purposively selected after taking the primacy of ethical considerations around research into consideration. The developed instrument may be used as it is, or adapted or extended for research beyond the limits of this study. This study could be valuable in assisting professional athletes to avoid financial distress after their sporting careers end. The study will also be of interest to sport governing bodies, the leadership of professional sports clubs, sports agents, legal advisors, accountants, tax experts, financial planners and other financial advisors to improve their understanding of the financial needs and current levels of financial literacy amongst professional athletes. / Tallose werkende mense spaar lewenslank vir hulle aftrede. Die loopbane van professionele sportlui is taamlik kort en boonop kan verskeie risiko’s voortydig 'n einde aan 'n sportloopbaan maak. Om verskeie redes sukkel professionele sportlui buitendien om die beroepswêreld ná ʼn sportloopbaan te betree. Daarom is dit noodsaaklik dat hulle finansieel geletterd raak terwyl hulle nog jonk is. Die speler-netwerkteorie (SNT) bied 'n geskikte teoretiese raamwerk vir hierdie studie aangesien dit toegespits is op die inligting wat deur 'n netwerk om professionele sportlui wat verstandige finansiële besluite nastrewe, vloei. Ten eerste is 'n raamwerk ontwikkel vir die finansiële vaardighede waaroor professionele sportlui vir volhoubare finansiële welstand moet beskik. Hiervoor is halfgestruktureerde onderhoude van aangesig tot aangesig met 27 ondervraagdes gehou. Op grond van SNT is die ondervraagdes gekies uit 'n netwerk van beïnvloeders wat professionele sportlui se finansiële besluite kan bepaal. Die raamwerk het berus op die uitslag van hierdie onderhoude waarin oop vrae gestel is. In die tweede gedeelte van hierdie gelaagde studie is 'n artefak of navorsingsinstrument ontwikkel waarmee die finansiële geletterdheid van professionele sportlui getoets kan word. Die oorkoepelende navorsingsontwerp vir hierdie kwalitatiewe studie is aan wetenskaplike ontwerpnavorsing ontleen. 'n Tweede ronde onderhoude is met 10 van die 27 ondervraagdes in die eerste ronde onderhoude gevoer. Die 10 ondervraagdes is doelbewus ná inagneming van die voorrang van etiese navorsingsoorwegings gekies. Hierdie instrument kan óf onveranderd gebruik word óf aangepas word vir navorsing wat buite die perke van hierdie studie val. Hierdie studie kan voorkom dat professionele sportlui ná 'n sportloopbaan in finansiële nood verkeer. Dit kan ook sportbeheerliggame, die bestuurders van beroepsportklubs, sportagente, regsadviseurs, rekenmeesters, belastingdeskundiges, finansiële beplanners en ander finansiële adviseurs help om die finansiële behoeftes van professionele sportlui en hulle vlak van finansiële geletterdheid beter te begryp. / Batho ba bantši ba tšea maphelo a bona ka moka a ge ba šoma ba leka go hwetša methopo ya ditšhelete ka nepo ya gore e ba tšwetše pele ka bophelo go ya go ile le ka morago ga ge ba rotše modiro.

Notre travail de recherche explore de manière comparée le développement du neuromarketing aux Etats-Unis et en France. Nous commençons par analyser la littérature sur le neuromarketing. Nous utilisons comme cadre théorique et méthodologique l’Actor Network Theory (ANT) ou Théorie de l’Acteur-Réseau (dans le sillage des travaux de Bruno Latour et Michel Callon). Nous montrons ainsi comment des actants « humains et non-humains »: acteurs-réseaux, traces (publications) et controverses forment les piliers d’une nouvelle discipline telle que le neuromarketing. Notre approche hybride « qualitative-quantitative », nous permet de construire une méthodologie appliquée de l’ANT: analyse bibliométrique (Publish Or Perish), text mining, clustering et analyse sémantique de la littérature scientifique et web du neuromarketing. A partir de ces résultats, nous construisons des cartographies, sous forme de graphes en réseau (Gephi) qui révèlent les interrelations et les associations entre acteurs, traces et controverses autour du neuromarketing. / Our research explores the comparative development of neuromarketing between the United States and France. We start by analyzing the literature on neuromarketing. We use as theoretical and methodological framework the Actor Network Theory (ANT) (in the wake of the work of Bruno Latour and Michel Callon). We show how “human and non-human” entities (“actants”): actor-network, traces (publications) and controversies form the pillars of a new discipline such as the neuromarketing. Our hybrid approach “qualitative-quantitative” allows us to build an applied methodology of the ANT: bibliometric analysis (Publish Or Perish), text mining, clustering and semantic analysis of the scientific literature and web of the neuromarketing. From these results, we build data visualizations, mapping of network graphs (Gephi) that reveal the interrelations and associations between actors, traces and controversies about neuromarketing.

Abstract in English, Afrikaans and Zulu / The aim of the study was to develop a critical posthumanist and democratic theory that may be applied in the teaching and learning of Life Sciences in South Africa in order to achieve an expanded form of democracy that would not discriminate between human and nonhuman. Though both critical posthumanist and democratic theories have been used in pedagogical studies separately, this study focused on the development of a merged and broader theory that has elements of both of the theories. The term nonhuman, as used here, does not specifically refer to non-person individuals only. Rather, it also refers to people who are regarded by the dominant humans as nonhumans – inferiors and subalterns. The latter group of people include the poor, women, children, people of colour and the disabled. Owing to this binarisation characteristic of the Life Sciences as a subject – which it adopts from the nature of science, its curriculum, and pedagogical approaches – the impression is given that as the master of the universe, the human has unlimited power over all other entities. These other nonhuman entities are then regarded as resources for the use of humans. Yet, it is this attitude which has caused humans to abuse nonhumans to the extent that the earth is facing the catastrophe of the Anthropocene. The adoption of a critical education approach characterised by the development of a critical posthumanist and democratic theory that may be applied in the teaching and learning of Life Sciences is essential in dealing with the issue of the Anthropocene that is threatening the earth currently. This study thus seeks to adopt a critical education approach through the introduction of democracy into the teaching and learning of Life Sciences, specifically so that humans would get to a position where they would consider nonhumans as entities with which they co-exist, and entities with equal agency within the environment. The recognition of the need for democracy would allow the humans to treat the nonhumans (such as the environment and ‘subalterns’) with respect, as their compatriots; and by doing that, the harrowing issues leading to the catastrophe of the Anthropocene could be either avoided or averted. / Die doel van die studie was om ’n kritiese posthumanistiese en demokratiese teorie te ontwikkel wat op die onderrig en leer van Lewenswetenskappe in Suid-Afrika toegepas kan word om ’n uitgebreide vorm van demokrasie daar te stel wat nie tussen menslik en niemenslik sal diskrimineer nie. Hoewel kritiese posthumanistiese sowel as demokratiese teorieë apart in pedagogiese studies gebruik word, het hierdie studie op die ontwikkeling van ’n saamgesmelte en breër teorie wat elemente van beide teorieë bevat, gefokus. Die term niemenslik soos wat dit hier gebruik word, verwys nie spesifiek net na niepersoon-individue nie. Dit verwys eerder ook na mense wat deur die dominante mense as niemense – minderes en ondergeskiktes – beskou word. Die laasgenoemde groep mense sluit die armes, vroue, kinders, mense van kleur en gestremde mense in. Vanweë hierdie binêre eienskap van die Lewenswetenskappe as ’n vak – wat dit as gevolg van die aard van wetenskap, sy kurrikulum en pedagogiese benaderings aanvaar het – word die indruk geskep dat die mens as heerser van die heelal onbeperkte mag oor al die ander entiteite het. Hierdie ander niemenslike entiteite word dan as hulpbronne vir gebruik deur mense gesien. Dit is egter hierdie houding wat veroorsaak het dat mense niemense misbruik, in so ’n mate dat die aarde die katastrofe van die Antroposeen in die gesig staar. Die aanneem van ’n kritiese onderrigbenadering wat gekenmerk word deur die ontwikkeling van ’n kritiese posthumanistiese en demokratiese teorie wat by die onderrig en leer van Lewenswetenskappe gebruik kan word, is noodsaaklik om die kwessie van die Antroposeen wat die aarde tans bedreig, te hanteer. Hierdie studie wil dus ’n kritiese onderrigbenadering volg deur middel van die bekendstelling van demokrasie by die onderrig en leer van Lewenswetenskappe, in die besonder sodat mense in ’n posisie sal wees waar hulle niemense as entiteite saam met wie hulle ’n bestaan moet voer, en entiteite met gelyke verteenwoordiging in die omgewing, sal beskou. Om die behoefte aan demokrasie te erken, sal die mense toelaat om die niemense (soos die omgewing en “ondergeskiktes”) as hulle landgenote met respek te behandel; en deur dit te doen, kan die pynlike kwessies wat tot die katastrofe van die Antroposeen sal lei, moontlik vermy of afgeweer word. / Inhloso yalolu cwaningo kwakungukusungula umbono obucayi owenziwa ngemuva kokuphila komuntu nentando yeningi engasetshenziswa ekufundisweni nasekufundeni kwesayensi yezempilo eNingizimu Afrika ukuze kuzuzwe uhlobo olwandisiwe lwentando yeningi olungeke lubandlulule phakathi kwabantu kanye nokungebona abantu.

La mise à l’échelle (scaling up) est un processus qui vise à accroitre l’impact et la pérennité des effets d’innovations jugées prometteuses. Les publications à ce sujet sont en progression importante dans le domaine de la santé depuis une vingtaine d’années. Toutefois, ces processus ont été étudiés de manière essentiellement technique malgré l’importance soulignée dans la littérature d’y prendre en compte des questions évolutives de sens et de valeurs. Ceci est particulièrement significatif pour les innovations de promotion de la santé, construites sur les capacités et collaborations de différents acteurs qui y partagent et négocient diverses vues sur les problèmes, les actions à entreprendre et leur but. Les contenus de ces innovations sont susceptibles d’évoluer de manière significative dans la mise à l’échelle, et d’affecter la fonction d’impact et pérennité du processus. Peu d’études, cependant, mobilisent des théories et méthodologies explicites à cet égard. Cette thèse s’inscrit dans une vision sociale de la mise à l’échelle et propose d’ajouter le concept de cadre interprétatif, ou « frame », à son outillage conceptuel ; elle vise à explorer l’utilité de cette notion au regard de la dynamique sociale de la mise à l’échelle d’innovations complexes de promotion de la santé. La thèse poursuit deux objectifs : 1) développer une articulation théorique de nature sociale pour la mise à l’échelle intégrant la notion de frame ; et 2) explorer l’utilité des frames comme ‘représentations’ pour documenter l’évolution du contenu des innovations au cours de leur mise à l’échelle. La réponse au premier objectif s’appuie sur une perspective de complexité des interventions en tant que réseaux dynamiques d’acteurs pour conceptualiser la mise à l’échelle comme une expansion de réseaux où le framing des questions de santé évolue au travers des relations entre acteurs. L’articulation théorique développée combine la sociologie de l’innovation - théorie de l’acteur-réseau - et les perspectives des frames pour envisager ceux-ci en tant que ‘représentations’ ou ‘interactions’. En réponse au second objectif, l’approche ‘représentationnelle’ aux frames est appliquée à l’étude d’un cas de mise à l’échelle d’innovation éducative à caractère intersectoriel concernant le développement de jeunes enfants socialement désavantagés. Sur la base de documents cadres qui balisent les phases ‘pilote’ et ‘programme à l’échelle’ de l'innovation, une analyse critique de frames est pratiquée au regard de la capacité du programme à grande échelle à supporter l’action sur les inégalités sociales de développement des enfants et l’équité. Les résultats illustrent des différences significatives de définitions du ‘problème’ du DJE et de la solution préconisée pour le programme à grande échelle, qui constituent des améliorations, mais aussi certaines ‘détériorations’ au regard des inégalités et de l’équité. En tant que constructions réalisées à partir des ‘produits’ du processus social qui s’opère dans le réseau intersectoriel des acteurs, les frames comme ‘représentations’ analysés de manière critique sont utiles pour expliciter et caractériser l’évolution des contenus des innovations et leurs conséquences pour la mise à l’échelle. Mobilisés dans un échange constructif avec les acteurs concernés, les frames pourraient constituer un outil intéressant pour favoriser la réflexivité à l’égard de ces processus et de l’impact et de la durabilité des effets des innovations portées à grande échelle. Cette thèse contribue de manière théorique à la littérature de santé publique en clarifiant l’utilité des frames et la manière dont ce concept peut être mobilisé pour documenter la dynamique de la mise à l’échelle d’innovations complexes de promotion de la santé. / Scaling up is a process that aims to increase the impact and sustainability of the effects of innovations deemed promising. Publications on this subject have markedly increased in the field of health over the past twenty years. However, these processes have essentially been studied in a technical way, despite the importance underlined in the literature to take into account their evolving meanings and values. This is particularly significant for health promotion innovations, built on the capacities and collaborations of different actors who share and negotiate various views on the problems, the actions to be taken and their goal. The contents of these innovations are likely to evolve significantly during scaling up, affecting impact and sustainability goals of the process. Few studies, however, mobilize explicit theories and methodologies in this respect. This thesis is part of a social vision of scaling up, and proposes to add the concept of ‘frame’ to its conceptual tools; it aims to explore the usefulness of this notion with regard to the social dynamics of scaling up health promotion innovations. The thesis pursues two objectives: 1) to develop a theoretical articulation of a social nature for scaling up, integrating the notion of frame; and 2) to explore the usefulness of frames as ‘representations’ to document the evolution of the content of innovations during their scaling up. The response to the first objective is based on a complexity perspective of interventions as dynamic networks of actors to conceptualize scaling up as an expansion of networks where the framing of health issues evolves through the relationships between the actors. The theoretical articulation developed combines the sociology of innovation - actor-network theory - and the perspectives of frames to consider them as 'representations' or 'interactions'. In response to the second objective, the 'representational' approach to frames is applied to the study of a scaling up case concerning an intersectoral educational innovation for the development of socially disadvantaged young children. On the basis of framework documents which mark out the 'pilot' and 'at scale program' phases of the innovation, a critical analysis of frames is carried out with regard to the capacity of the large-scale program to support action on the social inequalities in child development and equity. The results illustrate significant differences in definitions of the ECD ‘problem’ and of the recommended ‘solution’ for the at scale program, which constitute improvements, but also some ‘deteriorations’ with regard to inequalities and equity. As constructions made from the 'products' of the social process that takes place in the intersectoral network of actors, the frames as 'representations' critically analyzed are useful for explaining and characterizing the evolution of the contents of innovations and their consequences for scaling up. Mobilized in a constructive exchange with the actors concerned, the frames could constitute an interesting tool to promote reflexivity with regard to these processes and to the impact and sustainability of the effects of innovations carried out on a large scale. This thesis contributes theoretically to the public health literature by clarifying the usefulness of frames and the way in which this concept can be mobilized to document the dynamics of the scaling up of complex health promotion innovations.

This master’s thesis investigates generative AI-art through the lens of actor network theory. By focusing on the role of images in datasets as a material that effects both AI-models and artworks, the decisively non-human agencies generative AI-models can be said to possess, and the traces and associations that generative AI-models imbue artworks with, this thesis aims to investigate art that has been created with GAN-models as well as contemporary text-to-image diffusion-models, by way of similar premises. Forgoing common discussions and questions regarding the status of AI-art as art that inundate many a reasoning regarding this topic, this thesis instead investigates the use of generative AI to make images and art with an understanding of it as a multifaceted practice that can be observed and experienced in a variety of ways.  General topics such as the way images are used to train AI-models, the blurry connections between trained images and generated images, the way AI-models can be used and interacted with by using prompts as well as different kinds of interfaces and AI-Image-generators, are investigated, followed by the analysis of a number of artworks for which generative AI has been used. Throughout this study generative AI-art emerges as a both novel and oftentimes contested artform that is defined by direct and indirect connection to other media, a varied understanding of what it is that the artificial intelligence appears to do, and a use of the AI-artwork as a means to comment the mediums emerging characteristics.

La prestation coordonnée de soins de santé primaires (SSP) a été éprouvée comme améliorant la qualité et l’accès des soins prodigués aux Canadiens. Plusieurs études ont notamment confirmé les avantages des infirmières praticiennes (IP) et des modèles interprofessionnels en SSP pour le système de santé. Les écrits suggèrent toutefois que l’intégration des IP en SSP est jalonnée de tensions et restructurations en raison d’une confusion supposée de leur rôle. À ce jour, les recherches ont principalement ciblé les barrières et facilitateurs de l’intégration du rôle des IP. Une analyse critique des dynamiques socioprofessionnelles et politiques de l’intégration des IP n’a toutefois pas encore été réalisée. Une ethnographie critique combinant la Théorie de l’acteur-réseau et les concepts foucaldiens de discours, savoir et pouvoir a permis l’examen des interactions sémiotiques caractérisant certains milieux de SSP. Différents modèles interprofessionnels de SSP (2 centres de santé communautaire, 2 équipes de santé familiale et 2 cliniques dirigées par les IP) ont été investis. Les données issues d’entrevues semi-dirigées avec des IP (n=23), d’observations directes de milieux et de rencontres interprofessionnelles, et d’analyse documentaire ont été soumises à une analyse thématique puis une analyse critique de discours. Les résultats montrent que la valeur morale des IP, les finalités organisationnelles des milieux de SSP, les normes de pratique, la collaboration interprofessionnelle et la prise en charge des patients disposent les IP à la négociation de leur rôle et à certains enjeux socioprofessionnels et politiques qui génèrent plusieurs contrecoups: pluralisme de leurs rôles professionnels, dissonance identitaire, sentiments d’incompétence et d’incertitude, glissements discursifs dans leurs propres discours, et divers états émotionnels et souffrances. Ces contrecoups commandent diverses stratégies d’adaptation et de résistance permettant aux IP de gérer ces tensions. Plusieurs entités non-humaines (inscription des clientèles, discours de soutien aux médecins et espaces physiques) émergent comme acteurs agissant sur l’intégration et la négociation du rôle des IP en SSP. Cette étude permet de décrire le processus de traduction du rôle de l’IP en SSP qui problématise certains discours tenus pour acquis en SSP. Elle permet également de proposer une nouvelle définition de l’intégration du rôle des IP en SSP.

The aim of this study is to explore heritage processes within contemporary urban planning in Sweden, which is done through a single-case study. The point of departure for the study is the management of Havrekvarnen, an early modernist industrial building within an urban development area of Nacka, Sweden. Through parallel decisions by the County Administrative Board and the local Municipality in 2016, the building was firstly, listed with the strongest legal, cultural, and historical protection available, and secondly, the municipal urban regulations were changed so that the landowner was given permission to pursuit a reconstruction of the building, replicating its original appearance. As such the case constitutes a hitherto unique example of a listed future reconstruction in Sweden. The study examines how the process took place, focusing on actors and critical junctures involved in the execution and how the description of the building's heritage-values changed. The study uses a composite theoretical framework of authorized heritage discourse and actor network theory. To this an explaining-outcome process tracing is applied as method. Through a sequential process of collecting empirical data, in the form of archival records and interviews, the process was mapped through the conceptualization of a causal mechanism. The method had not previously been used in the field of art history and was chosen as such with a tentative approach. The study gives an extensive presentation of the legal and practical framework surrounding heritage processes within urban planning in Sweden, as well as puts the study within a local historical context. The results of the study show that within the observed case, a trade-off situation between authenticity and aesthetic historical values arose, caused by the poor technical condition of the building: the aesthetic values were deemed to take precedence in the assessment. The study also shows how antiquarian consultants have had a decisive influence on the process of legislative enabling of the reconstruction of Havrekvarnen. The research design’s use of process tracing to map heritage processes is thus deemed useful for future enquiries within the field of art history and heritage studies.
