The attentional state of operators is one of the main reasons for errors during human control of complex systems, and controlling these errors is critical especially in aeronautics, where errors are directly linked to safety and lives might be at stake. In particular, excessively high or low task demands encountered during the operation of such systems result in varying levels of mental workload and engagement which are linked with the operator performance. This research project adopts a Neuroergonomics approach and investigates the use of brain measurement techniques to monitor the attentional state of the operator under ecological conditions. We studied the behavior of the operator under both excessively low and high task demands with the use of multiple physiological and neurophysiological measurement techniques. Our results show that it is possible to use such techniques to characterize the attentional state. We then analyze the potential of real time application for such techniques. We investigated signal processing and analysis tools to improve the real-time usability of brain signals in ecological conditions, and proposed solutions towards the development of brain computer interfaces for assisting the human operator

This work is an attempt at a comparative study of the domestic organization within the alpine domain. The first part is concerned with a discussion of a number of epistemological and methodological issues related to the development of the interdisciplinary field of the "family history". The second part is devoted to an ethnographic and historical analysis of a valley of the piedmontese alps (italy). Through this micro-analytical focus, various chapters discuss the received wisdom ol alpine "family forms". A rethinking of quantitative methods, eco-demographic models and le play's categories goes along with the sketch of an ideal-typical approach. This analytical tool is developed in the comparative exploration which occupies the third part, where the data stemming from a number of ethnographic and historical researches carried on in the alps are examined by means of an interpretative reading

The subject of this study ecological conditions of the growing stock in the low mountains of the occidental rif in morocco. Cork oak (quercus suber) is the species of these woodlands. The regressive dynamics of the vegetation was of major interest. In the past, these cork oak were subject to a management project, which was never finished for reasons of accessibility and finance. Today the degradation of the rif area is a big ecological problem. During 4 years of investigation we dealt with the role of climatic and pedological conditions and particularly with the relation between plant species and ecological variables, using of "factor analyses of correspondances" (f. A. C. ). Further anthropological and sociopolitical factors were taken into account. Important remarks have been made concerning the impact of fire not only on group dynamics but also on mortality and burning losses. The speed of stand types regression was measured by examination of two aireal photographs, which were taken within a scope of 20 years. Finally the development of an original synthesis of photographic materiel out of superposition of cartographic material became possible. It shows the regressive dynamics of the three growing stocks of ahl serif, beni issef and soumata. During this study it became apparent that there is not equilibrium between the vegetation and its environmental factors. The vegetation is not at its climax. In fact, the low mountains of the occidental rif have suffered since many ages from degradation as a result of cutting and burning due to cultivation and pasture. We note that the witnesses of the ancient landscape have been registered by the soil profiles and underlined by the presence of characteristic species. By this study we want to attract the attention of the. .

The purpose of this thesis was to estimate and to determine the impacts of the agricultural policies on the cereal supply in the long-run-period by agro-ecological zones. The description of the historical, quantitative and institutional elements caracterized the different agricultural policies since 1960s and segmented the long period into four significative parts. The cereal supply model lead to the construction of the supply function related to the Nerlove model. The originality of this approach consisted of analyzing statistically the cereal supply function, not only as a national supply function, but as the aggregation of regional supply function defined from the agro-climatic parameters to the level of the agro-ecological zones. It permits to conduct a regional analysis to get the supposed impacts of the different agricultural policies and to provide new tools for a possible regionalization of the agricultural policies inside the country, and for a better definition of the orientations of cereal production

The Cetoniidae to be found in Fontainebleau are members of the Coleoptera, widespread in Europe, and whose saprophagous larvas live inside cavities of hollow trees. They form a guild which plays a major part in the recycling of ligneous matter in natural forest ecosystems, and they are closely linked to the old states of sylvigenetic cycles. The biology of these species shows noteworthy features suggesting K-type strategies, which is exceptional for coleoptera insects. They undergo a strong decline given the fact they are eliminated by the common forest management. The species Osmoderma eremita (Scopoli, 1763) is part of the priority species of the European directive called " Flora and Fauna Habitats ". They can be used as bioindicators of the biodiversity in saproxylic organisms of forest-type ecosystems, because of their big size and easy identification
Saint-Aubert, Jean-Baptiste de. "Impact of aging on human decision-making in ecological conditions." Electronic Thesis or Diss., Sorbonne université, 2023. http://www.theses.fr/2023SORUS511.
Any given day of a human’s life is made of countless decisions, that are influenced by the way our brain handles perceptive inputs, focuses attentional resources, mobilizes memory, or tries to learn from past choices. These processes change throughout lifespan, and human aging impacts the complex interplay of various cognitive and environmental factors that composes decision-making. Appropriate decisions often rely on a balance between exploring new possibilities and exploiting known options, and several studies have reported that aging shifts decision strategies from exploration to exploitation. However, little is known on how age affects exploration strategies and their neural substrates, let alone in uncertain, real-life environments. The main objectives of this doctoral thesis were: i) to characterize the impact of aging on explorative behavior during probabilistic reward learning; ii) to study the consistency of age-related effects in abstract value-based decision-making and in ecological, spatial decision-making; iii) to understand how neural correlates of decisions processes are shaped in mobile conditions. The methodological approach relied on an in-depth analysis of the best design and modeling choices of the decision tasks used to characterize the exploration-exploitation tradeoff. It also required mobile electroencephalography (EEG) recordings, that we validated by capturing brain correlates subtending cognitive processes during active landmark-based navigation with young adults. With a large-scale desktop-based behavioral study, we first confirmed that older adults rely significantly less on exploration than young adults, although not necessarily to the expense of performance and efficiency, thus using more parsimonious explorative strategies. Second, by using a novel spatial decision task that involved active motion in ecological conditions, we found that older adults can use more random, sub-optimal exploration than young adults in highly uncertain environments where subjects are provided with sparser information about the reward distribution. These findings challenge the classic view of the exploration-exploitation dichotomy based on decision-making paradigms that use abstract representations of options and rewards. Brain activity analysis during the active spatial decision task revealed that older adults presented delayed and less pronounced feedback-related negativity over fronto-central areas than young adults, who showed earlier and stronger visual processing of the negative feedback over visual cortical areas. This confirms previous findings on impaired reward processing during probabilistic learning in older adults, and extends them to active, spatial decision-making scenarios. Overall, these works highlight the need for enriching decision-making paradigms with more ecological setups that engage a broader set of cognitive processes involved in daily-life decision-making. It also stresses the necessity of taking into account the high inter-individual heterogeneity of age-related effects, e.g., by extending our set of behavioral models to more accurately depict exploration strategies in older individuals. Better understanding the multi-facets effects of aging on these mechanisms will be key in a future where it has an increasingly prominent role. Complementing the above main contributions focusing on decision-making throughout healthy aging, an aside project was conducted to assess EEG-based brain responses in blind subjects that received an optogenetic visual restoration therapy. This project was part of the multi-centric phase I/II clinical study PIONEER, which involves a cohort of patients affected by retinitis pigmentosa, a disease that leads to complete blindness over the course of adulthood. The EEG study provided objective evidence of partial visual recovery during a perceptual decision-making task, by demonstrating a modulation of occipital brain activity as a function of visual stimulation

Dispersal is the movement of individuals with potential consequences on gene flow. The distribution patterns of metapopulations and communities in the landscapes result from the inter and intra-individual variations of dispersal. The selection pressures due to human-driven landscape changes cause the apparition of specific movement strategies, with a growing contrast between strategies adapted to resource searching inside patches, and patch searching inside landscapes. The quantitative analysis of M. Jurtina dispersal behaviour allowed us to highlight a strategy adapted to long distance dispersal, the “direct moves”, which is different from the “foray loops” strategy that was known for this species, and is adapted to local short-distance exploration. Besides, in ectotherms activity is strongly dependant on meteorological conditions. We showed that this effect applies to dispersal too, that the dispersal strategies of M. Jurtina are differently affected, and that it changes the functional connectivity at the landscape scale. Moreover, we examined the dispersal behaviour of M. Jurtina along a gradient of agricultural intensification, and showed how dispersal is affected by habitat loss and environmental stochasticity. Finally, we estimated the potential corridor role of an agri-environment scheme set up in European landscapes: the grassy field margins. We used a combination of individual-based simulations of movement, and field surveys of movement inside grassy field margins and habitat patches to estimate this corridor function
