Les incapacités motrices lourdes engendrent des situations de handicap au cours desquelles l’autonomie du corps et du sujet sont bousculées. Les attendus et les évidences du corps valide sont suspendus. Ne pouvant plus agir directement sur elle-même ou sur son environnement, la personne en situation de handicap doit passer par l’intermédiaire d’un dispositif d’aide polymorphe constitué à la fois d’aides humaines et techniques. Au cours de chacune des interactions avec ce dispositif, les limites entre soi et l’autre, entre l’intérieur et l’extérieur, se brouillent.A partir de trois enquêtes ethnographiques réalisées auprès de personnes en situation de handicap vivant à domicile, la recherche doctorale a pour objet l’analyse de cette expérience corporelle. Dans une première partie, la thèse montre que la singularité de cette expérience repose sur le principe d’une distribution du corps, alternant entre déconstruction de soi et renégociations empiriques des frontières à partir de la définition d’une intimité. La recherche distingue ensuite trois formes possibles d’une existence au quotidien avec des incapacités motrices. Chacune d’entre elles se traduit par unedistribution singulière des frontières de l’identité / Severe motor impairments generate disability situations in which the autonomy of body and of the subject are disrupted. Expectations and taken-for-granted attitudes regarding the valid body are challenged. No longer in capacity to act directly on themselves or on their environment, persons with disabilities must interact with polymorphic help devices consisting of both human and technical aids. In these interactions, limitations between self and others or between inside and outside are blurred.Based on three ethnographic studies conducted with persons with disabilities living at home, the doctoral research aims at analyzing their specific corporal experience. The first part of the dissertation analyzes the experience of people with severe motor impairments as an experience of a distributed body, alternating between self-destruction and empirical negotiations of body frontiers with reference to intimacy. The second part distinguishes three forms of the experience of everyday life with severe motor impairments, which result in different distributions of the frontiers of self

The prevailing discourse of “resistance vs. acceptance” in IT implementation research mostly personalizes the issue as “users” versus IT implementers (e.g., managers, CIOs, CMIOs, etc.). This kind of discourse has created an IT-implementer-centric attitude among IS scholars and practitioners. The IT-implementer-centric attitude, while embraces “acceptance” as a desirable reaction almost unconditionally, frequently holds for minimizing or more conservatively suppressing “resistance” to IT implementation. In other words, the mainstream IT implementation research, almost completely, treats “users” as passive recipients whose choices, as they face pre-developed/pre-designed/pre-rolled-out technology being implemented, can only be defined on a spectrum from “acceptance” to “resistance.” The current research study, however, offers an alternative perspective that views the “resistance vs. acceptance” duality “from the other side,” i.e., from the perspective of the supposed “resistors” or “acceptors” themselves. Through a review of the literature, this study first identifies major drawbacks of the extant theories and models of IT implementation research. Next, drawing on an interpretive paradigm of research (more specifically, phenomenological sociology), this study investigates a real world case of healthcare IT implementation. The results of the aforementioned literature review and case investigation subsequently form the basis for the study’s proposed theoretical account, which provides an unprecedented understanding and explanation of how actors representing different stakeholder groups, among which people who are routinely called “users” are but one group, experience IT implementation as they live their everyday lives. The proposed theoretical account is lastly used as a guide for crafting both practical and research prescriptions with respect to managing IT-involved change occasions.
