Cette thèse examine la formation des citoyens à l'Âge de l'information en comparant les visions et les pratiques d’alphabétisation et d’enseignement de la culture informatique aux enfants et au grand public aux États-Unis, en France, et en Union soviétique. Les programmes d'alphabétisation et d'acculturation informatique ont été lancés dans ces trois pays dans les années 1970 avec pour objectif l'adaptation des individus à la vie dans la société informatisée telle qu'elle était envisagée par les savants, penseurs et praticiens dans chaque contexte culturel et sociopolitique. La thèse porte sur les idées et influences de trois personnes qui ont joué des rôles importants dans la promotion des initiatives d'éducation en informatique dans chacun des pays étudiés : Seymour Papert aux États-Unis, Jean-Jacques Servan-Schreiber en France, et Andrei Ershov en Union Soviétique. Selon ces pionniers, devenir alphabétisé ou cultivé en informatique signifiait plus qu’acquérir des compétences vis-à-vis de l’ordinateur ou bien apprendre à être un utilisateur passif du micro-ordinateur. Chaque pionnier envisageait une façon distincte d’incorporer la machine dans la manière de penser et d'être des individus -- comme une augmentation cognitive aux États-Unis, comme une culture en France, ou bien comme un partenaire dans l'Union Soviétique. Les hybrides hommes ordinateurs en résultant exigeaient tous une relation ludique à l'ordinateur personnel conçu comme un espace libre, non structuré et propice à l’exploration créatrice. Dans cette étude, je trace la réalisation de ces hybrides hommes-ordinateurs à partir de leurs origines dans les visions des quelques pionniers, de leur incorporation dans le matériel, les logiciels, et les programmes éducatifs, de leur développement dans les expériences locales avec les enfants et les communautés, et, enfin dans leur mise en œuvre à l'échelle de la nation. Dans ce processus d'extension, les visions des pionniers se heurtent à de puissants imaginaires sociotechniques (sociotechnical imaginaries) de l’État. Je montre alors pour chaque cas, comment, suite à la confrontation avec ces imaginaires, les visions des pionniers ne sont pas pleinement réalisées. En conclusion, je propose une lecture de la manière dont les imaginaires du Vingtième siècle de citoyens alphabétisés ou cultivés en informatique s’étendent au-delà de leurs points d'origine et se connectent à des aspects contemporains de la constitution des humains dans un monde informatisé. / In this dissertation I trace the formation of citizens of the information age by comparing visions and practices to make children and the general public computer literate or cultured in the United States, France, and the Soviet Union. Computer literacy and computer culture programs in these three countries began in the early 1970s as efforts to adapt people to life in the information society as it was envisioned by scholars, thinkers, and practitioners in each cultural and sociopolitical context. The dissertation focuses on the ideas and influence of three individuals who played formative roles in propelling computer education initiatives in each country: Seymour Papert in the United States, Jean-Jacques Servan-Schreiber in France, and Andrei Ershov in the Soviet Union. According to these pioneers, to become computer literate or computer cultured meant more than developing computer skills or learning how to passively use the personal computer. Each envisioned a distinctive way of incorporating the machine into the individual human’s ways of thinking and being—as a cognitive enhancement in the United States, as a culture in France, and as a partner in the Soviet Union. The resulting human-computer hybrids all demanded what I call a playful relationship to the personal computer, that is, a domain of free and unstructured, exploratory creativity. I trace the realization of these human-computer hybrids from their origins in the visions of a few pioneers to their embedding in particular hardware, software, and educational curricula, through to their development in localized experiments with children and communities, and finally to their implementation at the scale of the nation. In that process of extension, pioneering visions bumped up against powerful sociotechnical imaginaries of the nation state in each country, and I show how, as a result of that clash, in each national case the visions of the pioneers failed to be fully realized. In conclusion, I suggest ways in which the twentieth-century imaginaries of the computer literate citizen extend beyond their points of origin and connect to aspects of the contemporary constitutions of humans in the computerized world.

The proliferation of the internet and associated online activities exposes users to numerous information security (InfoSec) threats. Such online activities attract a variety of online users who include novice computer users with no basic InfoSec awareness knowledge. Information systems that collect and use sensitive and confidential personal information of users need to provide reliable protection mechanisms to safeguard this information. Given the constant user involvement in these systems and the notion of users being the weakest link in the InfoSec chain, technical solutions alone are insufficient. The usability of online InfoSec systems can play an integral role in making sure that users use the applications effectively, thereby improving the overall security of the applications. The development of online InfoSec systems calls for addressing the InfoSec problem as a social problem, and such development must seek to find a balance between technical and social aspects. The research addressed the problem of usable security in online InfoSec applications by using an approach that enabled the consideration of both InfoSec and usability in viewing the system as a socio-technical system with technical and social sub-systems. Therefore, the research proposed a socio-technical framework that promotes the development of usable security for online information systems using online banking as a case study. Using a convergent mixed methods research (MMR) design, the research collected data from online banking users through a survey and obtained the views of online banking developers through unstructured interviews. The findings from the two research methods contributed to the selection of 12 usable security design principles proposed in the sociotechnical information security (STInfoSec) framework. The research contributed to online InfoSec systems theory by developing a validated STInfoSec framework that went through an evaluation process by seven field experts. Although intended for online banking, the framework can be applied to other similar online InfoSec applications, with minimum adaptation. The STInfoSec framework provides checklist items that allow for easy application during the development process. The checklist items can also be used to evaluate existing online banking websites to identify possible usable security problems. / Computer Science / D. Phil. (Computer Science)

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / This dissertation has as its theme the communication processes developed organizations in the digital media / corporate blog, which is enclosed in the examination of socio-technical strategies of visibility and legitimacy undertaken in 16 blogs the corporate Medium-Large Business and Large Business of the blogsphere Brazilian. The overall objective is to develop an array of strategies for socio-technical visibility and legitimacy for corporate blogs with the intention of responding to problem: what strategies sociotechnical practiced organizations in promoting corporate blogs that search visibility and legitimacy '. The methodology uses empirical research proposal mediated computer (Johnson, 2010), from two main methods for research qualitative: the hidden field observation and non-participatory and triangulation methodological techniques. The theoretical approach and methodology developed in this research focused on the finding that 68.75% of companies are conspicuous by their field of study sociotechnical strategy of visibility positioned at the level of relationship intermediate and 75% by sociotechnical strategy of legitimacy positioning also returned to the relationship and intermediate level. The positioning of relationship besides having preferably is at intermediate level and therefore absorbed in the socio-technical strategies of visibility and legitimacy in more than half corporate blogs the field of study. / A presente dissertação tem como tema os processos comunicacionais desenvolvidos pelas organizações na mídia digital/blog corporativo, que é delimitado no exame das estratégias sociotécnicas de visibilidade e legitimidade empreendidas em 16 blogs corporativos das Médias-Grandes Empresas e Grandes Empresas da blogosfera brasileira. O objetivo geral é desenvolver uma matriz de estratégias sociotécnicas de visibilidade e legitimidade para os blogs corporativos com o intento de responder à problemática: quais estratégias sociotécnicas praticadas nos blogs corporativos pelas organizações promovem a busca de visibilidade e legitimidade?. A metodologia utiliza a proposta de pesquisa empírica mediada por computador (JOHNSON, 2010), a partir de dois principais métodos para pesquisas qualitativas: a observação de campo encoberta e não participativa e a triangulação de técnicas metodológicas. O percurso teórico e metodológico desenvolvido nessa pesquisa incidiu na constatação de que 68,75% das empresas do campo de estudo primam pela estratégia sociotécnica de visibilidade com posicionamento de relacionamento no nível intermediário e 75% pela estratégia sociotécnica de legitimidade com posicionamento também voltado ao relacionamento e com nível intermediário. O posicionamento de relacionamento além de ter preferência se encontra em nível intermediário e, portanto, absorvido nas estratégias sociotécnicas de visibilidade e legitimidade em mais da metade dos blogs corporativos do campo de estudo.

Influential actors refer to smart grids as a revamped version of the energy systemwhen they argue for alternative energy pathways, and assign demonstration projects with the task of turning prospects about the future into functional configurations. This thesis explores notions of the smart grid future that are implicitly conveyed in Swedish smart grid strategy and planning documents. The purpose of this thesis is to describe and analyse how a smart grid is assembled in a Swedish demonstration project. Inspired by Science and Technology Studies (STS), it explores this process through interviews, document studies and participant observation. By combining concepts such as sociotechnical imaginaries, material participation and translations, this study sheds light on the negotiations, tensions and struggles at play in the process of making smart grids functional. This study examines how included and excluded users make sense of the smart grid and of their own role in shaping the future. What imaginaries do the actors involved in the project draw on? What materialities take part in shaping the smart grid, and what user engagements are encouraged? The aim of the study is to seek an enhanced understanding of how smart grids are made, of the different forces that shape this process and, ultimately, of the reality of Swedish households as part of a smart grid in the making. This study shows that making a smart grid functional is not as feasible as the smart grid imaginaries suggest, and it finds potential in user engagements that are suppressed within the current market regime, which is primarily arranged around economic incentives. / Inflytelserika aktörer beskriver smarta elnät som ett sätt att modernisera energisystemet och sjösätter demonstrationsprojekt med uppgift att omforma potentiellt omvälvande visioner till fungerande konfigurationer. Denna avhandling undersöker vilka föreställningar om smarta elnät som implicit förmedlas i svenska strategi- och planeringsdokument, och beskriver och analyserar hur dessa visioner påverkar hur ett smart elnät sätts samman i ett svenskt demonstrationsprojekt. Inspirerad av teknik- och vetenskapsstudier (STS) analyserar avhandlingen denna process med hjälp av intervjuer, dokumentstudier och deltagande observation. Genom att kombinera teoretiska begrepp som sociotekniska föreställningar, materiellt deltagande (material participation) och översättningar, undersöker studien de förhandlingar, spänningar och konflikter som inträffar när smarta elnät blir till. Studien belyser också hur inkluderade och exkluderade användare förstår det smarta elnätet och sin egen roll när det gäller att forma framtiden. Vilka föreställningar om framtiden använder sig de aktörer som är involverade i projektet av? Hur inkluderas olika materialiteter i utformningen av det smarta elnätet och vilka typer av användare uppmuntras av den konfigurering som sätts samman i projektet? Syftet med studien är att nå en djupare förståelse för dels hur smarta elnät blir till och de olika krafter som bidrar till denna process, och dels hur svenska hushåll konstrueras som en del av smarta elnät. Studien visar att det är inte så enkelt att skapa fungerande smarta elnät som föreställningarna gör gällande, och den hittar en outnyttjad potential hos användarna vars deltagande dikteras av marknadsmässiga villkor och ekonomiska incitament snarare än ansvar och delaktighet.

Online marketing activities play an increasingly important role for organization in connection with the development of internet based technologies and their positive reception by the society. The aim of this dissertation is to design an artefact that would support the decision making of marketing specialists and thus the management of online marketing activities. The starting point is an explorative research among Czech companies, which identifies the issues felt as problematic and the needs of the selected set of organizations. Introduced at the same time is the current state of use of selected tools for online marketing by these organizations, and the situation is compared with worldwide development. The output of this explorative research, the examination of scientific literature, and a critical analysis serve as a basis for designing an own method, Genoma, whose purpose is to support the decision making of marketing specialists, and thereby also the management of marketing activities in internet-mediated environment. This method is presented as Deming (PDCA) cycle, which enables it to be used not only separately, but also as part of other frameworks for the management of marketing activities (e.g. the frameworks PMF, MCPF and RACE, which are presented in the dissertation). The Genoma method uses mainly the genetic algorithm for selecting a suitable portfolio of online marketing tools for a particular campaign. The selection is made on the basis of expected feedback at the level of social interaction, meeting the given marketing targets, and the financial demands of the individual tools. The prerequisite of using this method is a knowledge base that includes the area of sociotechnical interaction, which is based on interpreting phenomena related to the internet-mediated environment and the features of complex networks. Methodically, this dissertation builds on the complementary relationship of the behavioural (social informatics) and the design type of research (design science research). The final assessment of the suitability of the proposed method is done on the basis of a multiple case study, which uses also an own program created in C#, implementing the genetic algorithm used in the Genoma method.

(in English): This thesis focuses on the theories of Human-computer interaction, called by the selected authors "postcognitivistic", that react critically to the cognitivistic approach of the first- wave HCI. The working hypothesis of this work is to view the broader context of interface of technological objects as a medium of a sociotechnical relation between technological artefacts, human actors and the society. The goal of the thesis is to develop a theoretic-philosophical analysis and the comparison of how the primary sources focused on the HCI theory and sociotechnical systems, together with the chosen literature on the new media theory and philosophy of technology, contribute to the contemporary discussion about the contextual aspects of HCI, including the question of how seeing the interface as a sociotechnical relation influences the work of the designers who have to deal with the complexity of contemporary design problems.

In der vorliegenden Arbeit wird die Rolle grafischer Prototypen bei der Gestaltung von Mensch-Maschine-Systemen untersucht. Diese grafischen Modellierungen von Gestaltungsentwürfen sollten den Aufbau mentaler Repräsentationen fördern und somit die Lösung von Gestaltungsproblemen unterstützen. Diese Annahme wird in zwei Experimenten überprüft. Die Erkenntnisse werden in die Methode zur prospektiven Gestaltung von Mensch-Maschine-Systemen integriert und in einer Fallstudie auf ihre Praktikabilität untersucht. Damit leistet die Arbeit einen Beitrag zur Untersuchung der Rolle von Visualisierungen in der Gestaltung von Mensch-Maschine-Systemen. Gestaltung von Mensch-Maschine-Systemen wird als partizipativer Problemlöseprozess betrachtet, der der integrierten Gestaltung sozialer und technischer Komponenten von Mensch-Maschine-Systemen dient. Zur Unterstützung der Gestaltung wird der Einsatz von Prototypen, Modellierungen der Gestaltungsproblemen und -entwürfen, diskutiert. In aktuellen Methoden zur Gestaltung von Mensch-Maschine-Systemen kommen unterschiedliche Prototypen zur Unterstützung der Gestaltungsaktivitäten Entwerfen (Konstruktion von Prototypen) und Evaluation (Kommunikation durch die Elaboration von Prototypen) zum Einsatz. Sowohl die Konstruktion als auch die Elaboration von Prototypen sollte den Aufbau mentaler Repräsentationen fördern (Neyer, Doll & Moeslein, 2008; Sachse, Hacker & Leinert, 1999; Smith & Browne, 1993). Dieser Aufbau mentaler Repräsentationen stellt eine zentrale Funktion von Prototypen dar, da angemessene Repräsentationen des Gestaltungsgegenstands als Voraussetzung für gute Gestaltung und für die Evaluation durch Beteiligte angesehen werden (Eason, Harker & Olphert, 1996; Novick & Hmelo, 1994; Sachse & Hacker, 1997). Welche Form von Prototypen dafür besser geeignet ist, wurde bislang nicht empirisch geprüft. Die Hauptfragestellungen dieser Arbeit beziehen sich auf den Effekt der Konstruktion von Prototypen sowie die Effekte der Konstruktion und Elaboration grafischer im Vergleich zu narrativen Prototypen auf mentale Repräsentationen. Diesen Fragestellungen wird in zwei Experimenten und einer Fallstudie im Anwendungsbereich der Gestaltung von Mensch-Maschine-Systemen nachgegangen. In dem ersten Experiment wurde die Unterstützung der Entwurfsphase, d.h. der Aufbau mentaler Repräsentationen durch die Konstruktion von Prototypen untersucht. Probanden konstruierten grafische oder narrative Prototypen eines Mensch-Maschine-Systems (Experimentalgruppen) oder rezipierten Informationen zum Mensch- Maschine-System (Kontrollgruppe). Die Konstruktion von Prototypen führte zu besseren mentalen Repräsentationen des Problemraums. Die Form der Prototypen beeinflusste die Güte der mentalen Repräsentationen nicht, jedoch wurde die grafische Modellierungsnotation besser bewertet. Im zweiten Experiment wurde die Funktion von grafischen und narrativen Prototypen für die Kommunikation von Gestaltungsvisionen untersucht. Die Fragestellung war, wie sich die Elaboration grafischer oder narrativer Prototypen auf die mentalen Repräsentationen, die zur Elaboration benötigte Zeit sowie die Bewertung der Modellierungsnotation auswirkt. Mit grafischen Prototypen konnten in kürzerer Zeit mentale Repräsentationen des Problemraums aufgebaut werden, die mehr Elemente enthielten als die narrativer Prototypen. Zudem wurden grafische Prototypen erneut besser bewertet. Darüber hinaus wurde die Funktion grafischer Prototypen in einer Fallstudie erprobt. Die Methode zur prospektiven Gestaltung von Mensch-Maschine-Systemen (Hamborg, Schulze & Sendfeld, 2007) wurde in dieser Arbeit weiterentwickelt und zur Einführung von Standardsoftware eingesetzt. Grafische Prototypen kamen in Kombination mit Gestaltungsheuristiken sowohl in der Entwurfs- als auch der Evaluationsphase zum Einsatz. Es zeigte sich, dass die Methode durchführbar und praktikabel ist und die Gestaltung unterstützt. Grafische Prototypen wurden dabei als verständlich und nützlich bewertet. Zusammenfassend zeigen die Ergebnisse der Untersuchungen, dass grafische Prototypen das Entwerfen und die Kommunikation von Gestaltungsentwürfen unterstützen, indem sie zum Aufbau mentaler Repräsentationen des Problemraums beitragen. Der Einsatz grafischer Prototypen erlaubt es z.B., die Folgen von Technologie- Einführungen im Vorfeld berücksichtigen zu können. Damit hat diese Arbeit über den reinen Erkenntnisgewinn hinaus einen praktischen Nutzen bei der Verbesserung der methodischen Unterstützung der Gestaltung von Mensch-Maschine-Systemen. In weiteren Untersuchungen sollten die vermuteten Effekte von Prototyping auf die Gestaltungsgüte empirisch adressiert werden und die gewonnenen Erkenntnisse in quasiexperimentellen Studien repliziert werden.

Implementeringen av ERTMS/ETCS har haft betydande inverkan på lokförarnas roll och arbetssituation. Denna studie undersöker konsekvenserna av ERTMS/ETCS gällande lokförarnas ansvar, grad av kontroll och den viktiga balansen mellan automation och mänsklig kompetens. Intervjuer med lokförare och branschexperter visade på en tydlig förändring från aktivt beslutsfattande och operativ kontroll till en mer passiv roll där lokförarna följer systemets instruktioner. Med ERTMS/ETCS har lokförarnas självständighet minskat, eftersom systemet kan ta över kontrollen om förarna avviker från systemets rekommendationer. Därmed förskjuts maktbalansen mot systemets fördel och minskar lokförarnas inflytande. För att upprätthålla en balans mellan bevarandet av lokförarnas kompetens och användningen av avancerade system övervägs en strategi där lokförarna utbildas som "Säkerhetsoperatörer". Faktorer såsom ljuskänslig display och dess positionering är tydliga tecken på att ERTMS/ETCS inte beaktat den sociala aspekten ur ett sociotekniskt perspektiv. / The implementation of ERTMS/ETCS has had a significant impact on the role and work situation of train drivers. This study examines the consequences of ERTMS/ETCS in terms of train drivers' responsibilities, level of control, and the crucial balance between automation and human competence. Interviews with train drivers and industry experts revealed a clear shift from active decision-making and operational control to a more passive role where train drivers follow the system's instructions. With ERTMS/ETCS, train drivers' autonomy has decreased as the system can take control if the drivers deviate from its recommendations. Consequently, the power dynamics shift in favor of the system, diminishing train drivers' influence. To maintain a balance between preserving train drivers' competence and utilizing advanced systems, a strategy is being considered to train train drivers as "Safety Operators." Factors such as the light-sensitive display and its positioning indicate that ERTMS/ETCS has not considered the social aspect from a socio-technical perspective.

[pt] A transição para uma economia circular (EC) requer modelos multidimensionais para a definição de objetivos e metas de circularidade em diferentes horizontes temporais, prazos, diretrizes circulares setoriais, políticas públicas nacionais e regionais, entre outros. Visando fornecer estruturas consistentes para decisões de negócios baseadas em evidências, com implicações para os níveis meso e macro de CE, o objetivo desta dissertação é propor um modelo de mensuração estratégica para monitorar e avaliar o desempenho da circularidade no nível micro, integrando GMA e dois métodos multicritério de tomada de decisão. Os principais resultados deste estudo envolvem: (i) uma matriz morfológica genérica composta por oito parâmetros e seus possíveis estados para definir e representar visualmente possíveis cenários de transição de CE para uma determinada organização que pretende evoluir através de transições de CE; (ii) o uso potencial de uma abordagem metodológica híbrida (que combina GMA com dois métodos MCDM) para selecionar os indicadores C mais relevantes para cada estratégia-R pode ser destacado; (iii) uma lista inicial de 58 C-indicadores e métricas associadas a dez estratégias-R e um conjunto de 38 C-indicadores selecionados por meio da adoção do método híbrido AHP-TOPSIS; (iv) definição de dez indicadores de circularidade compostos associados às estratégias R, bem como um Índice de Performance de Circularidade (IPC) geral, e um procedimento passo a passo para calculá-los em diferentes cenários de transição de CE. De uma perspectiva de transição circular, os resultados destacam implicações práticas para organizações e cadeias de valor, uma vez que o modelo foi concebido para ser aplicado em diferentes contextos de negócio, especialmente em organizações que irão definir seus objetivos de circularidade e respectivas agendas relativas à transição para uma economia circular. / [en] The concept of a circular economy (CE) transition requires multi-level frameworks regarding the definition of goals and targets for different time horizons, desired change timeframes, sectoral circularity guidelines, and national and regional public policies, among other factors. Aiming to provide consistent frameworks for evidence-based business decisions with implications for the meso and macro levels of CE, the objective of this dissertation is to propose a strategic measurement model to monitoring and evaluating the circularity performance at the micro level by integrating GMA and two multicriteria decision-making methods. The main findings of this study are: (i) a generic morphological matrix comprising eight parameters and their possible states to define and visually represent possible CE transition scenarios for a given organization that aims to evolve through CE transitions; (ii) the potential use of a hybrid methodological approach (that combines GMA with two MCDM methods) for selecting the most relevant C-indicators for each R-strategy could be highlighted; (iii) an initial list of 58 C-indicators and metrics associated to ten R-strategies and a set of 38 selected C-indicators by adopting the hybrid AHP-TOPSIS method; (iv) definition of ten composite C-indicators associated with the R-strategies, as well as an overall Circularity Performance Index (CPI), and a step-by-step procedure to calculate them in different CE transition scenarios. From a CE transition perspective, the results highlighted practical implications for organizations and value chains, once the proposed model is designed to be applied in different business contexts, especially in those organizations that will define their circularity targets and respective agendas concerning CE transitions.

AI is a phenomenon that does not only manifest itself as a disruptive technology, but also entails a paradigmatic shift with conceivably unprecedented and unforeseeable consequences for society and the human condition. This technology with its components Big Data and Machine Learning/algorithms has evoked critical reactions because of ethical concerns that follow on the backwash of its ubiquitous and ever more expanding use. Whose voices are presently raised and what contributions can actually be expected from the information systems (IS) discipline – an academic field that is prone to scrutinize phenomena that emerge when the social and technological system interact? By reviewing a systematically defined selection of the latest IS research literature and analyzing the critical perspectives, this study displays current themes in the IS discipline concerning critique of AI. The accumulation and clustering of the results can provide an answer to the question of what themes appear in the critique of AI in the IS discipline and whether a critical standpoint towards detrimental effects of AI use in society is formed. Social critique, which has no longstanding tradition in IS research, would be necessary to succeed in offering a well-informed and science-based guidance on how to face AI as a society and with the human condition as a focal point.
