Повний текст джерелаThe research was focused on the accuracy of memories and effects of cognitive aging. According the constructive memory, our research addressed on the aged effects on false recognition (distinguishing semantic vs. Source-based false recognition). According to this, three main aims were investigated; 2/ to demonstrate a higher age-related susceptibility for source-based false recognitions with naturalistic material or not; 3/ to demonstrate the multi-processes origin (constructive encoding / source monitoring processes) of false recognition susceptibility with age due to a dysexecutive difficulties (according to the frontal aging hypothesis) for both types of false recognition. The results obtained were discussed in the light of various theories, and allowed us to establish an integrated model of aging effects on false recognition phenomenon

Повний текст джерелаWhat are factors that can delay or accelerate senescence? Researchers are seeking these factors at molecular, cellular and life history traits level. Recent studies have firmly showed that the slow-fast continuum, sexual selection and food availability are factors shaping variability in senescence patterns. Surprisingly, the influence of sociality on senescence has been less investigated. The aim of this thesis is to fill this gap and to study the influence of sociality on senescence thanks to an extensive dataset spanning 25 years of study on free-ranging Alpine marmots (Marmota Marmota), a long-lived and highly social mammal. Alpine marmots live in family groups typically composed of a dominant pair, of sexually mature and immature (yearling) subordinates, and of pups of the year. Male subordinates help to raise pups, they are also called helpers. We showed in dominant females that litter size declined at 10 years of age and reproductive success at 8 years of age. In both sexes, survival was constant with age until dominants were between 6 and 8 years of age and declined markedly thereafter. We also showed that the number of helpers at birth and during adult life were independent and additively increased female dominant longevity and lifetime reproductive success. Moreover, we provided evidence that the presence of helpers at birth and during adult life strongly influenced survival senescence and that this influence was sex-specific. Indeed, females benefiting from the presence of helpers at birth showed a delayed and less intense senescence while males born with helpers showed a earlier and faster senescence. The presence of helpers during adult life was beneficial for both sexes by delaying senescence and decreasing its intensity. Sociality, more specifically cooperative breeding and its benefits and costs associated, is an important predictor of the diversity of survival senescence in Alpine marmot. Finally, we worked at the interspecific level and showed that sociality in mammals delayed the onset of senescence

Повний текст джерелаIn France, the growing population of older adults losing their autonomy points to an increase in the demand for institutional care in the midst of a socio-professional, financial, moral and political crisis. The development of social robots promises to improve quality of life for the elderly and reduce the workload of staff in care facilities. However, in practice, these robots are not widely adopted because of technical, ethical, cultural, and socio-economic limitations. Their design has been called techno-centric, out of touch, influenced by science fiction or not participatory enough, resulting in products not suited to the needs, issues, values, and complexity of human social environments. Rooted in the design sciences and holding that social innovation must guide technological innovation, this thesis examines the relevance of social robots in tackling the nursing homes crisis. It approaches their rise not as a technical challenge, but as a vector of social transformation, and adopts a systemic lens to understand their place as a new component of a relational network of humans and artefacts. Through the implementation of two field projects, this project-grounded research (PGR) study in design examines the ways in which social robots adapt to the ecology of aging in nursing homes, their systemic impact, and the expectations of facility users. The first project includes a qualitative observation of a care facility without robots, a design ethnography of the use of six robots in seven facilities, and five co-design workshops. The second project builds a participatory design fiction exploring prospective scenarios. This work offers a reading of the current reality as well as potential socio-technological futures of life in care homes, and presents empirical, methodological and theoretical contributions. By analysing the unsuitability of current social robots in nursing homes from an ecological perspective, this thesis proposes a transformation of innovation and design approaches for these environments. In particular, it advocates a situated understanding of the reality of care prior to any technological development. It suggests the creation of new project formats opening more space for collaboration. It puts human-robot complementarity back into perspective separate from dominant imaginaries and advocates breaking away from solutionist thinking in favour of systemic social change. From a methodological point of view, this work explores the integration of a triple approach to design: ecological, participatory and speculative. This symbiotic methodology helps to rethink the role of users in determining their future and to question the implications of using robots in nursing homes to redefine preferable outcomes. Finally, this research produces a theoretical reflection on the symptomatic place of social robots in the socio-political transformation of care and proposes to mobilise them no longer as a solution but rather as a research tool in establishing what constitutes preferable futures for life within facilities

Повний текст джерелаThere is an incredible diversity of lifespan in the animal kingdom ranging from a few days for small gastrotrichs worms to several hundred of years for some bivalves or tortoises. This amazing diversity has long questioned biology researchers. The growing interest in the phenomenon of aging, mainly due to the increase in life expectancy in humans, has questioned researchers on processes that determine patterns of longevity and ageing. On the one hand, biomedical and biogerontological studies helped describe numerous cellular and physiological mechanisms related to aging. Among these mechanisms, oxidative stress has been identified as playing a major role, through life-time accumulation of damage generated by production of metabolic free radicals. On the other hand, the development of evolutionary theories of aging has contributed to understanding ultimate origins of ageing and of the diversity of life history traits. However, these approaches, although complementary, have long remained separated and works that integrate physiological mechanisms such as oxidative stress in an evolutionary perspective have known only recent developments. In this thesis, we studied how mechanisms such as oxidative stress and its associated costs produced during reproduction or immune response could play a role in the evolution of patterns of ageing in birds and mammals by (i) studying the role of antioxidants as key resources involved in adaptive trade-offs between reproduction and survival through age, (ii) studying the long-term effects of the early environment, (iii) studying the relationship between inflammatory response and contrasted patterns of ageing and longevity between birds and mammals, (iv) focusing particularly on immune regulatory mechanisms, emphasizing their crucial role in fitness of hosts, especially late in life. Overall, our results highlight the importance of physiological constraints in terms of key resources limitation (i.e. antioxidants) or damage caused during costly and destructive activities and on intra-and inter-specific patterns of ageing

Повний текст джерелаHabitat loss and fragmentation are considered as major threats to biodiversity in forests, one of the species-richest terrestrial ecosystems worldwide. The structural simplification and the loss of key habitat elements resulting from forest harvesting threaten forest biodiversity. Through the analysis of datasets shared between laboratories and two original datasets created during this thesis, I intended to evaluate the role for associated beetle diversity of several components of the saproxylic habitat network at local and landscape scales. The effect of local environmental variables has been evaluated and the biodiversity associated with ageing stands, forest reserves and isolated non-forest trees were explored. In parallel, we have analyzed the main technique used to sample our study group. We highlighted (i) strong effects of spatial or temporal replication of sampling on data, but (ii) negligible effects of data simplification by excluding a time-expensive family on results. We demonstrated significant effects of forest setting aside on the restoration, mainly of dead wood and tree microhabitats, but also on associated saproxylic beetle assemblages. Extended rotations in ageing stands did not provide such positive effects. Besides, we evidenced that a high density of forest reserves in the landscape (over 20%) seems necessary to efficiently favor the saproxylic fauna. In addition, we observed that a significant proportion of saproxylic species prefer non-forest solitary tree habitats. The whole saproxylic fauna is therefore not hosted by forests. These non-forest saproxylic structures have to be included in conservation strategies dedicated saproxylic biodiversity

Повний текст джерелаSince several years, virtual reality is widely used in neuropsychology, especially for the study of spatial cognition. The goal of its use is to respond to the lack of ecological validity of classical tests and to the lack of experimental control of assessments in real situations. The studies in the domain of spatial cognition reveal the complexity of learning and navigation activities in large scales spaces and suggest a multifactorial origin to spatial learning and navigation in older adults. The aim of this thesis will be first to verify the ecological validity of our virtual reality application, with a direct comparison of spatial learning and navigation performances between real and virtual learning conditions, in young and old participants. Another goal will be to confirm the hypothesis on the role of executive and memory decline in age-related spatial learning and navigation difficulties. Finally, the role of motor control in spatial learning in large scale spaces, which is poorly studied within the framework of aging, will be tested. With the use of a virtual reality application, requiring memorizing a path in a virtual district replicating a district of Bordeaux, we have studied the effects of aging on spatial memory and navigation performances. We compared real and virtual, active and passive learning conditions and studied the relation between spatial memory and navigation performances with neurocognitive measures and self-report questionnaires on everyday navigation difficulties. Our main results showed a negative effect of aging on the performances in our application, with pattern of results similar between real and virtual learning conditions in young and old participants. We obtained a good relation between measures from our virtual application and everyday navigation difficulties reported by the young participants but no differences between young and old participants on everyday navigation difficulties. These results confirm the good ecological validity of our virtual application and favor the use of direct navigation and spatial memory measures instead of self-report questionnaires for older adults. They also showed directly the role of memory and executive decline in older adults’ navigation difficulties. Contrary to the results obtained with the young participants, the motor control had a negative effect on navigation performances in older adults. We will discuss of the neurocognitive hypothesis already proposed concerning the origin of navigation difficulties due to aging. Also, the role of motor activities and dual-task effect on spatial navigation performances in older adults will be examined
