The purpose of this study was to examine the effects of the use of technology on students’ mathematics achievement, particularly the Florida Comprehensive Assessment Test (FCAT) mathematics results. Eleven schools within the Miami-Dade County Public School System participated in a pilot program on the use of Geometers Sketchpad (GSP). Three of these schools were randomly selected for this study. Each school sent a teacher to a summer in-service training program on how to use GSP to teach geometry. In each school, the GSP class and a traditional geometry class taught by the same teacher were the study participants. Students’ mathematics FCAT results were examined to determine if the GSP produced any effects. Students’ scores were compared based on assignment to the control or experimental group as well as gender and SES. SES measurements were based on whether students qualified for free lunch. The findings of the study revealed a significant difference in the FCAT mathematics scores of students who were taught geometry using GSP compared to those who used the traditional method. No significant differences existed between the FCAT mathematics scores of the students based on SES. Similarly, no significant differences existed between the FCAT scores based on gender. In conclusion, the use of technology (particularly GSP) is likely to boost students’ FCAT mathematics test scores. The findings also show that the use of GSP may be able to close known gender and SES related achievement gaps. The results of this study promote policy changes in the way geometry is taught to 10th grade students in Florida’s public schools.

There is an abundance of research that examines disability and technology in the context of computers and the Internet, however few have examined disability and mobile devices. Also largely absent from existing literature are the voices of disabled people themselves. This dissertation draws upon science and technology studies (STS) and disability studies to address these gaps by conducting in-depth qualitative research that examines disabled people’s experiences using smartphones and tablets. At its core, this dissertation aims to provide insight on the following: 1) an understanding of how disability is perceived in the digital age and the subjective meanings of access, inclusion and equality; 2) the ways in which mobile devices impact the lived experience of disability; and 3) how perspectives in disability studies and STS can be applied to understand the relationship between the body, disability and technology. The empirical contribution of this research draws from participant diaries and interviews with disabled people, as well as from open-ended questionnaires completed by mobile app developers. The concept of ‘subjectivities of disability’ is introduced to refer to the uniquely personal and individual experience of disability. Findings reveal that mobile device use amongst disabled people redefines their subjectivities of disability through socio-technical interactions whereby disabled people use their devices in ways that are integrated into their everyday lives and positively shapes how they view themselves in relation to their experience of disability. The responses from app developers reveal that there is a place for disability in the mobile market and that disabled people play a key role in making apps accessible. The data suggests that mobile devices facilitate access, inclusion and equality by integrating the body in ways that recognize and accommodate diversity. The results furthermore make it clear that the interaction between disabled people and mobile devices takes on an embodied and social characteristic. This research concludes that both on an individual level and collectively, disabled people are engaging with digital artifacts in ways that promote agency and independence as well as reshaping how disability is experienced and perceived in the digital age.

Sociologists of health and illness have tended to overlook the architecture and buildings used in health care. This contrasts with medical geographers who have yielded a body of work on the significance of places and spaces in the experience of health and illness. A review of sociological studies of the role of the built environment in the performance of medical practice uncovers an important vein of work, worthy of further study. Through the historically situated example of hospital architecture, this article seeks to tease out substantive and methodological issues that can inform a distinctive sociology of healthcare architecture. Contemporary healthcare buildings manifest design models developed for hotels, shopping malls and homes. These design features are congruent with neoliberal forms of subjectivity in which patients are constituted as consumers and responsibilised citizens. We conclude that an adequate sociology of healthcare architecture necessitates an appreciation of both the construction and experience of buildings, exploring the briefs and plans of their designers, and observing their everyday uses. Combining approaches and methods from the sociology of health and illness and science and technology studies offers potential for a novel research agenda that takes healthcare buildings as its substantive focus.

Race as a biological category has a long and troubling history as a central ordering concept in the life and human sciences. The mid-twentieth century has been marked as the point where biological concepts of race began to disappear from science. However, biological definitions of race continue to penetrate scientific understandings and uses of racial concepts. Using the theoretical frameworks of critical race theory and science and technology studies and an in-depth case study of the discipline of immunology, this dissertation explores the appearance of a mid-century decline of concepts of biological race in science. I argue that biological concepts of race did not disappear in the middle of the twentieth century but were reconfigured into genetic language. In this dissertation I offer a periodization of biological concepts of race. Focusing on continuities and the effects of contingent events, I compare how biological concepts of race articulate with racisms in each period. The discipline of immunology serves as a case study that demonstrates how biological concepts of race did not decline in the postwar era, but were translated into the language of genetics and populations. I argue that the appearance of a decline was due to events both internal and external to the science of immunology. By framing the mid-twentieth century disappearance of race in science as the triumph of an antiracist racial project of science, it allows us to more clearly see the more recent resurgence of race in science as a recycling of older themes and tactics from the racist science projects of the past.

This dissertation proposes an analysis of the governance of the European scientific research, focusing on the emergence of the Open Science paradigm: a new way of doing science, oriented towards the openness of every phase of the scientific research process, able to take full advantage of the digital ICTs. The emergence of this paradigm is relatively recent, but in the last years it has become increasingly relevant. The European institutions expressed a clear intention to embrace the Open Science paradigm (eg., think about the European Open Science Cloud, EOSC; or the establishment of the Horizon Europe programme). This dissertation provides a conceptual framework for the multiple interventions of the European institutions in the field of Open Science, addressing the major legal challenges of its implementation. The study investigates the notion of Open Science, proposing a definition that takes into account all its dimensions related to the human and fundamental rights framework in which Open Science is grounded. The inquiry addresses the legal challenges related to the openness of research data, in light of the European Open Data framework and the impact of the GDPR on the context of Open Science. The last part of the study is devoted to the infrastructural dimension of the Open Science paradigm, exploring the e-infrastructures. The focus is on a specific type of computational infrastructure: the High Performance Computing (HPC) facility. The adoption of HPC for research is analysed from the European perspective, investigating the EuroHPC project, and the local perspective, proposing the case study of the HPC facility of the University of Luxembourg, the ULHPC. This dissertation intends to underline the relevance of the legal coordination approach, between all actors and phases of the process, in order to develop and implement the Open Science paradigm, adhering to the underlying human and fundamental rights.

Cette thèse explore les implications politiques de la montée en puissance des normes internationales sur nos sociétés contemporaines et pose la problématique des dynamiques participatives des représentants des consommateurs au sein des formes de pouvoir non étatique à l'aide du cas de l'Organisation internationale de normalisation (ISO). Le renforcement du pouvoir des normes internationales et autres spécifications techniques soulève d'importants enjeux démocratiques qui portent aussi bien sur la représentativité des acteurs qui les élaborent, sur l'articulation des prérogatives publiques et privées dans la gouvernance de la mondialisation, que sur le rôle de l'expertise dans la reconnaissance de ces nouvelles formes de pouvoir. La participation du monde associatif intervient sur ces différents enjeux de manière complexe. Cette recherche s'inscrit à la suite des études en relations internationales/économie politique internationale sur les formes d'autorité non étatique et s'inspire du concept de traduction issu de la sociologie des sciences et techniques pour mettre en lumière le rôle des spécifications techniques dans la construction d'une société de consommation centrée sur la liberté de choix et la façon dont les associations de consommateurs se saisissent des arènes de normalisation pour y faire valoir des préoccupations collectives, leur expertise et leur identité. Cette thèse défend l'idée que les consommateurs participent à la construction de l'autorité des normes internationales par leur rôle dans la traduction qui permet de relier les spécifications techniques au fonctionnement des marchés, au cadre réglementaire de la loi et aux préoccupations sociétales. L'analyse repose sur une observation ethnographique des délibérations d'un comité technique de l'ISO, une recherche-­‐action, la réalisation d'entretiens et la consultation de documents d'archives de l'ISO. -- This thesis explores the political significance of the rise of international standards on contemporary societies and questions the participatory dynamics of consumers' representatives within nonstate forms of power, using the case of the International organization for standardization (ISO). The power granted to international standards and other technical specifications raises important democratic issues regarding the representativity of standard-­‐ writers, the public-­‐private relationships involved in this form of governance or the expertise sustaining the recognition of such new forms of power. The participation of civil society associations affect such issues in complex ways. This research relies on international relations/international political economy approaches of nonstate authority and takes inspiration from the concept of translation developed by science and technology studies to highlight the crucial role played by technical specifications in building a consumer society based on the freedom of choice as well as how consumers' associations take stock of standardization arenas to promote collective issues and claim their expertise and identity. This thesis argues that consumers contribute to the construction of the authority of international standards through their role in the translation that links international standards to the market society, the regulatory state as well as to societal preoccupation. The analysis is based on an ethnographic observation of deliberations within an ISO technical committee, a research-­‐action, interviews as well as on the consultation of ISO archives.

Internet évolue avec la société et les nouvelles technologies, mais ses usages restent centrés sur le principe communicationnel de partager ses idées, ses histoires avec d’autres personnes. Comprendre les modes de communication des internautes offre des défis de taille aux chercheurs. Malgré une riche littérature sur les usages d’Internet, peu d’études se sont penchées sur l’analyse en profondeur des habitudes des internautes ordinaires. Cette thèse a pour objet d’étude le partage de contenus en ligne, car il s’agit d’une pratique permettant de réfléchir sur le rapport des usagers à la technologie. En m’inspirant des travaux d’Henri Lefebvre et de Michel de Certeau, je mobilise le concept de la vie quotidienne, concept qui met en lumière les processus à travers laquelle les gens font sens de leur vie. Afin de mieux saisir le quotidien, lequel est mobile, fluide et multiple, des métaphores spatiales tirées d’études des sciences, technologies et société (STS) seront mobilisées. Les concepts d’espace fluide et de feu sont idéaux pour étudier les pratiques de partage de vidéo que l’on peut qualifier de mutables et adaptables. Dans cette thèse, l’accent est mis sur les expériences subjectives des internautes ; ainsi, j’ai adopté une méthodologie qualitative pour recueillir les témoignages d’une dizaine de participants décrivant longuement leurs pratiques. En effet, j’ai rencontré chaque personne à plusieurs reprises et nous avons discuté d’exemples spécifiques. À travers les thèmes récurrents qui ont émergé des verbatims, et dans la tradition de la théorisation ancrée, la première partie de l’analyse fournit une riche description du quotidien des participants. J’explore en particulier la façon dont les internautes adaptent leur partage sur leurs expériences des sites de réseaux sociaux, comment la vidéo est utilisée dans le maintien de leurs relations sociales, et comment le partage des vidéos complémente leurs conversations. Sachant que les pratiques en ligne et hors ligne se fondent l’une dans l’autre, la deuxième partie de l’analyse articule la complexité de la vie quotidienne et la fluidité des pratiques de partage à l’aide du concept de l’objet fluide pour traiter des aspects complexes, dynamiques et souples des pratiques des internautes ordinaires. Cette recherche qualitative fournit un portrait de l’expérience humaine qui est autant détaillé que possible. Elle permet de souligner que c’est dans une variété contextes non remarquables – car faisant partie intégrante de la vie quotidienne – que les Internautes naviguent et que les activités humaines sont sans cesse construites et transformées, ouvrant des possibilités vers de nouvelles façons de faire et de penser. La thèse poursuit un dialogue interdisciplinaire entre la communication (les Internet Studies notamment) et les études des sciences, technologies et société (STS), tout en apportant de nombreuses données empiriques sur les pratiques des internautes « ordinaires ». De plus, la thèse offre des métaphores capables d’ouvrir de nouvelles perspectives pour l’analyse des usages du Web social. Elle apporte également une contribution originale en intégrant des approches théoriques des pratiques quotidiennes avec la théorisation ancrée. Tant les fondements conceptuels et des approches méthodologiques développées ici seront des exemples très utiles pour d’autres chercheurs intéressés à poursuivre la compréhension des pratiques quotidiennes impliquant l’Internet, surtout quand ces derniers impliquent le visuel, l’émotif et le relationnel.

Smart grid research has tended to be compartmentalised, with notable contributions from economics, electrical engineering and science and technology studies. However, there is an acknowledged and growing need for an integrated systems approach to the evaluation of smart grid initiatives. The capacity to simulate and explore smart grid possibilities on various scales is key to such an integrated approach but existing models – even if multidisciplinary – tend to have a limited focus. This paper describes an innovative and flexible framework that has been developed to facilitate the simulation of various smart grid scenarios and the interconnected social, technical and economic networks from a complex systems perspective. The architecture is described and related to realised examples of its use, both to model the electricity system as it is today and to model futures that have been envisioned in the literature. Potential future applications of the framework are explored, along with its utility as an analytic and decision support tool for smart grid stakeholders.
