Bancou, Léo. "From being there to becoming together : Organizing co-presence in hybrid modes of working." Electronic Thesis or Diss., Université Paris sciences et lettres, 2024. http://www.theses.fr/2024UPSLD047.
Повний текст джерелаThis doctoral research explores the complex, multi-faceted nature of co-presence within hybrid work arrangements. Dominant understandings of co-presence often focus on ‘being there’ in physically or virtually shared spaces. However, this thesis proposes moving beyond co-presence as merely a socio-spatial situation, instead framing it as a dynamic, embodied process of becoming together. By emphasizing the relational and organizational underpinnings of co-presence, this research aims to capture the intricacies of social dynamics and collective organizational life in hybrid settings. Drawing on a process phenomenology perspective, the thesis examines co-presence as a lived bodily experience that manifests through diverse modalities across time-space and physical-virtual boundaries. This conceptualization challenges traditional notions of presence and absence, opening new avenues for understanding the fluidity of co-presence in technology-enabled work environments. Ultimately, this research seeks to answer: What does it mean to feel co-present in hybrid work arrangements, and how is it organized in these conditions?
Decamps, Jennifer. "Les modes amiables de rupture du contrat de travail." Thesis, Avignon, 2014. http://www.theses.fr/2014AVIG2039/document.
Повний текст джерелаThe ways to break a work contract amicably are booming . Even if the amicable break of the contractual relationship , from Article 1134 of the civil code , has been recognized for several decades , its lack of real understanding and use by the social legislation limits its use , even though its effectiveness,regarding the fixed period employment contracts and the training contract does not need to be proven any more ! The current revival of this way to break a contract comes from the creation of a new act : the 25 th june 2008 modernization of the labour market law . The conventional breach, supposed to be an act which permits to reinforce the safety of the relational breach has boosted the confidence of employers as well as employees, when the use of consualism , they had created, has to be broken .So, without really putting into question the breach itself the origin of which being the common law, the conventional breaking is the most likely act to put an end to the hegemony of unilateral acts of breach

Повний текст джерелаAlternative dispute resolution for individual labour cases are developing in most labour disputes. Labour law has accepted negotiated resolutions but imposing at the same time a restriction on possibilities of a conventional solution during the contract of employment and on the opposite allowing an absolute freedom to negotiate when the contract is breached. The challenge is to keep the guarantees of state justice with the combination of the best conventional solutions

Повний текст джерелаReporters professionalism can be considered in two different ways : 1 - group-recognition discourse, it is intended to make good the deficiency of journalism's definition (limits, skills, approach, role) : 2 - as a non-ability entirety, it emphasizes a proactise of the informative activity which is divided between both the demand for rationalization and expression. As a secular journalism model, reporting is looked into its historical origins (19th century), its expansion (thirty popular works analysis. 1890-1990) and its contemporary aspects (twenty reporters interviewed)

Повний текст джерелаFrom the definition of the "total social fact" by Marcel Mauss, we assum that hiring is an exchange which bring in more than the trath subject, here job. Maurice Halbwachs's analysis about individual "value" of a social group's representative, confirmed this problematic. We assum that recruitment produiced its own hierarchies, within the social groups. They still don't meet any instituted model : they are not explained by qualification systems, neither by graduation systems, nor by earned incomes. Hiring is a moment when every classification form is acting simultaneoulsy, without any prevailing one. Through recuitment operations, classification systems realised a sort of symbiosis, which produiced, "in fine", a normative definition of groups in their relation with employment. This research used varied materials : interviews and surveys with managers and wage earners, textual analysis of job offers

Повний текст джерелаThe central features of telework involve the use of telecommunications, advanced information technologies and the performance of work at an other location than traditional work place. The central question here is to establish the economic consequences induced by distant work for the firm and the social impact on workers. We have studied impacts of telework on the labour relation analysis to emphasis the main opportunities and problems which can occur. We have established a typology of organisational structures to focus the type of firms integrated telework. The main problem is concerning social links between workers and firms, hardly sustainable

Повний текст джерелаThe emergence of a wide variety of photonic structures over the past decades has enabled the realization of on-chip devices performing increasingly complex free-space optical functions. Among them, dielectric membrane structures have made it possible to implement a wide range of planar optical devices, ranging from resonant spectral filtering to beam shaping, with negligible losses. While these structures provide almost a full control of the radiated electromagnetic field, this control is usually static and determined by manufacturing. An increasing number of applications - such as free-space telecommunications, sensors for autonomous systems or imaging - require agile photonic devices, thus motivating the search for means of active control of the optical response to be implemented within the dielectric structures. To this purpose, various properties of graphene are proving promising. In particular, the capability to modulate its absorption opens up numerous prospects for the electrical and optical control of photonic structures that integrate graphene. This has led to the demonstration of various electro-optic and all-optical modulators, by leveraging the recently developed 2D material transfer processes, which have made it possible to obtain high-quality hybrid graphene/dielectric structures. In this context, the work presented in this thesis seeks to exploit graphene’s tunable absorption to achieve dynamic control of surface-addressable device’s optical response, in the special case of dielectric photonic structures operating in the near infrared. A generic coupled mode theory model is first developed and adapted to hybrid dielectric/ graphene structures in order to identify the key parameters for maximising the control allowed by graphene absorption. In the single resonance case, the system’s response is mainly determined by the critical coupling condition classically defined for the study of graphene’s absorption. In the two-resonance case however, a new control parameter – associated with the absorption difference between the resonances – provides an additional tunability factor. Different strategies for maximising this parameter are therefore proposed and the technological processes underlying their implementation are studied experimentally in order to assess - by means of Raman spectroscopy and photoelectron spectroscopy - their effect on the structural and chemical quality of graphene. The spatial modulation of graphene’s absorption – here proposed to differentiate the absorption induced on different optical modes – is then studied experimentally using structures exploiting the charge transfer effect at the interface between graphene and an oxide with high workfunction, namely tungsten oxide. The devices developed here allow to obtain a graphene’s chemical potential modulation of 0.1eV - characterized by nano-XPS (ANTARES beamline of the SOLEIL synchrotron) and Raman spectroscopy - which can lead to an absorption modulation higher than 70% for certain wavelengths. Ultimately, an active hybrid device architecture enabling dynamic control of the laser emission is proposed. This architecture is based on a vertical symmetry breaking membrane and allows us, in principle, to switch between two emission angles by modulating graphene’s absorption. The interest of these structures in achieving continuous tunability of the emission angle is also presented

Повний текст джерелаSince about ten years all the european countries have been more or less concerned by the economic crisis. The collective conflicts resulting from those circonstances have changed by nature and their importance. In order to resolve those problems every country can essentially have recourse to conciliation, mediation and arbitration procedures, being however tightly bound to industrial specific relations adapted to each nation

Повний текст джерелаIndividual labor cases are adjudicated to a special court: “le Conseil des prud'hommes”. The judges of this special court are elected by employers and employees. In most cases the law requires a two step process: conciliation and, if needed, adjudication. Another possible way is to try to resolve the conflict by reaching mutual understanding in the shadow of the law trough mediation. The purpose of this thesis is to study the current legal conciliation process for individual labor cases, while investigating the possible use of other Alternative Dispute Resolution modes, like mediation and co-mediation. Our research advocates the “mixed way” that involves the resort to judges, while attempting the use of ADR to get a mutually agreeable solution

Повний текст джерелаThe financial compensation of work realized by the employee is not limited to the wages only, but corresponds to a global remuneration responding to performance objective. A global movement of financial implication of employees to their own performance or to their firms is growing. It is translated by an evolution of remuneration : an individualization and an institutionalization. The individualization of remuneration is illustrated by an intensification of the contract of employment function and a development of original remuneration. Reversely, the institutionalization of remuneration consists in the attribution of variable and collective remuneration, not calculated function of individual work, but function of the firm global results. How to control this evolution of work relations ? An objectivation of individualization is trying to develop along the meaning of the contract of employment, stock-options attribution conditions, or a strict application of non-discrimination principle. An institutional gestion of remuneration is developing through collective mechanisms, like joint negotiations about SAYE and a better employee's representation, thanks to a new form of corporate governance

Повний текст джерелаThis study, which concerns the patterns of life of Athenian couples, is based on the data of a research which has been done with the participation of 1924 married women, of 15 to 45 years old, living in Athens area. Our problematic is founded on a double dimension. First of all, we have distinguished the variety of family models adopted by the couples-traditional or modern. Afterwards, we have examined the norms of housework distribution between the spouses looking for elements which could possibly differentiate it and we have also seen how these two sectors interact. In fact going through this study, it has been proved that the domestic activities do not occupy much of the time of the Athenian husbands although those same activities are a very important part of everyday life of the Athenian wives. Nevertheless, the most equal distribution, as well as the adoption of more modern patterns of life, (i. E. The innovating attitudes,) is associated with the young and educated couples and with the husbands who are white collars or employees. In addition, the exercise of a professional activity by the wives, strengthens, the participation of husbands in the domestic activities in Greece, as well in other countries. And it is among the professionally active women and their companions that we can see the existence of doubts as far as traditional family values are concerned

Повний текст джерелаThe framework of this thesis is the cooperative software development environment COO. COO uses transactional approach to handle concurrency control problems but it does not provide any guarantee about the quality of the software products. We propose to define constraints in order to have such guarantee. Unfortunately, the classical verification algorithms of constraints are not compatible with the nature of development activities. We define a new verification algorithm which is suitable for cooperative environment. Our results are: a hybrid approach Maïzena which uses semantic knowledge to restrict the accepted execution by the syntactical protocol of COO and allows to enclose cooperation in a security sphere; an algorithm to maintain the consistency of software products. This algorithm maintains constraints defined by temporal formulae. It is implemented in COO environment; a recovery mechanism which allows to split an activity to several ones and to uses cooperation to satisfy constraints

Повний текст джерелаWomen's participation in the labour force doesn't depend only on economic variables such as women' wage and family incom e. In fact we always have to take into account the impact of child care modes on this participation. For this reason, the presence of relatives in the household, who constitute a potential source for child care, has also an affect on woman's decision to participate in the labour force. Considering the impact of female participation on the labour market , we find that the increase in the number of women in the labour force has a negative effect on the wage level of younger workers

Повний текст джерелаThe present thesis develops the effects resulting from the social classifications concerning a certain youth: this is particularly advanced by studying the conditions of access to job by young people and by the confrontation of these results to the theory of the "professional transition" (J. Rose). The classification are analyzed as a necessary condition for the setting up of employment policies and particularly the measures called TUC-CES (collective usefulness jobs - solidarity employment contracts) on one hand, the TUC-CES people are fundamentally analyzed from the point of view and the mobilization strategies developed by institutions which appeal to these young people. On the other hand, this population (TUC-CES people) is analyzing by questioning the steps taken by young people: here, institutional determinations are strongly tied up with individual processes. The concepts of socialization and identity allow the construction of a framework which examines an original program of employment policy

Повний текст джерелаIn transitional economies, a hybrid mode of corporate governance – the clanic mode – refers to the interaction between the firm and its institutional environment through its participation in politics. It is characterized by socialization, predominance of informal practice and non market factors. It constitutes a recation of the firm towards its evolutive and turbulent institutional environment. In Ukraine, the relations between the firm and the authorities are based on clientelism through an exchange of resources. The firm deploys their political resources represented by votes of their employees in favor of political parties. It obtains form policymakers a favorable regulation through a rent provided via subventions.This thesis seeks to prove the existence of the relation between corporate political and economic resources. The firm invests available resources to obtain benefits. Political activity can be seen as profitable. Rent-seeking constitutes modus operandi of the clanic governance that allows to the firm to operate efficiently in a specific business environment. This mode of governance is also characterized by informal practices. The exchange of resources with policy-makers is made through informal networks whose configuration defines the perimeter of clanic structures

As this part, the comparative approach is the most indicated to tackle the problems related manners of workingman. Of cause, such option suppose that our must take into accunt workman skills in the two brewery, their knowledge, the ideas that they have of industrial system and of the work they carry out, their previous experience, their culture, the tradition which is tied up work, their frame and their manner of work appropriation. To aboard the problematic of manners of workingman, we refered to a theoric frame which can suggest the required conceptual basis and methodological. This object we manager to do a bibliographic review, which is relative work thematics, the oraganization behavior in intercultural situation, the transfer of technology and ergonomics. The methodology that we carry to grasp the manners of working is adopted classic means (observation, discussion, work analysis). The datos treatment which have been calleded required the use of camputer impliments. The (qualitative or quantitative) result of study permited to validate the hypothesis which suppose differences between the manners of workingman and to explain these one with the fact that workman move around a situation of technical, organization, cultural contraints which overdetermine as it were not only both the logics of actions, but as their activities or the process that they carry out. As well in the conception of technical objects as in the work representations, there are important differences, which allocate workmans in both brewery. The results of this study defined the typology of model to functioning operators

Повний текст джерелаOur essay on the changes in the condition of workers shows management of stronger type in "modernized" firms where workers are more closely controlled, hence entering the disappearance of the relative balance between managers' domination and the labour force, as at the time of the "Fordist compromise". The economic, technological, and social reorganization following the crisis of the 1970s resulted in workers' collectives being dismantled, in class solidarity vanishing, and in unions getting weaker. The "modern" firm has lost its integrative function by making jobs temporary and replacing them according to economic circumstances. Since then, the new balance has been favourable to managers. The traditional forms of workers' resistance have been harmed by the new management method where social control is omnipotent. To counteract the reinforcement of managers' control, new forms of rebellion have appeared : there are defensive rather than offensive, secret, and above all individual rather than collective. Temporary wage-earners, fearing social exclusion, have very little liberty left; the least resigned of them try to make the most of it. This movement is hardly controlled by the management and is a tool for reconquering the self-esteem that was lost in such firms where economic stakes outclass people's lot

Повний текст джерелаThe study of the Bellac labour market area, where most of the workers are employed in small factories or at subcontractors for the car-manufacturing industry, will be used to analyze the changes in employment and working-class identity. The first part will deal with the political and religious history of the region and the specicities of its recent industrialization. The second part will examine the organization of factories, the social life around them, then will focus on men and women's experiences, the way they consider work in general, whether they are currently employed or jobless (for a short or long period of time). We will discover that working environments are often organized according to "jobs" or the notion of expertise for a "post". The last part of the study will show how employees have to react to very diverse work situations and acquire new skills to adapt to a new work reality. People may be tempted to think that they have become autonomous and free, able to manage their own career path whereas they remain extremely vulnerable to the lack of job security, the weakering of collective protections, the individualization of careers and the uncernty of their futures

Повний текст джерелаThe concept of hybrid training, combining activities in presence and distance, most often supported by a digital platform, before 2020 was a niche solution, little recognized. It was forcibly democratized with the covid-19 pandemic, even forcing the emergence of a new form of hybridization where the two modalities merge. The first definition of hybrid training appeared in 1995, written by Didier Valdès in his thesis for Paris 2 Panthéon Assas. He pointed out a certain number of criteria essential to the design of such training. However, the historiography concerning the study of these, from a erspective of definition, evaluation and design, was quickly turned upside down by the emergence of web 2.0. The design criteria adopted became more and more numerous and technical, the authors interviewing only a part of the actors (teachers or students), without a global vision and without taking into account their real activity. This approach, not integrating the activity of their operators, leads to complex hybrid training courses to be followed both for students and teachers, who may even be resistant to Information and Communication Technologies (ICTs). ) employees, or even to training in general. We are therefore looking to observe a hybrid training taking into account the activity of the operators, in order to deduce design tracks more in line with it. We employ an ethnocentric methodology, based on the theoretical framework of the activity, with an associated method - in particular the notions of prescribed and real. We thus seek to go beyond the usual dichotomies with machine / without machine, and presence / distance. We refer particularly to the activity theory developed by Yrjö Engeström, and to the instrumental theory of Pierre Rabardel. We observe a hybrid module of initiation to information and Pix certification within a university course More specifically, we have retained for the analysis a chapter of the course comprising a 1h30 face-to-face session and work to be done remotely. All the data available over this observation period is used, i.e. a heterogeneous set including open observations in class, video recordings, interviews carried out with users and designers, questionnaire for students, collection of emails from the teacher, data generated through the IT platform, and presence on student workspaces and exchanges such as Facebook and Google Drive. These data are combined in quantitative and qualitative ways, and analyzed through the production of detailed chronologies, Engeström contradiction tables, and a revised version of Gaëtan Bourmaud's Method of Failures and Substitutions of Resources (MDSR). We highlight a clear gap between prescribed and actual training (that is to say between training designed and in situ), resulting from a design in use carried out by the actors - teachers and students. This implies paradigm shifts, particularly with regard to student autonomy, the objective of the training which disrupts the position of the teacher. This conception in use is the result of a collective work of the operators (teacher and students), practically leading to a redesign of the training according to the needs actually felt. The design of a hybrid training in accordance with this activity would thus suppose to use the distance for what it is, in order to facilitate the creation of a community of university learning

Повний текст джерелаLes machines de fabrication additive métallique actuelles sont dispendieuses et généralement peu productives. De plus, la plupart des pièces issues de la fabrication additive doivent être usinées après l’impression pour obtenir de bonnes tolérances géométriques. L’objectif de ce projet de recherche est de développer un système de fabrication additive hybride pouvant remplacer les machines d’usinage traditionnelles. Les systèmes hybrides combinent les avantages de la fabrication additive et de l’usinage dans un seul système. Ce mémoire présente le développement et la mise en service d’un système de fabrication additive hybride formant des pièces en aluminium à partir d’un filament d’Al4043. Ce système utilise une technologie innovatrice qui se base sur le principe de chauffage par induction. Le filament est fondu directement par induction à l’intérieur d’un tube, puis un flux d’argon permet à l’aluminium en fusion de s’éjecter du tube. Cette méthode permet de faire des préformes en aluminium qui peuvent être usinées afin d’obtenir une pièce finale. Cette technologie permettrait de fabriquer une machine hybride à faible coût tout en ayant un taux de déposition élevé. Le système a été installé sur un bras robotisé FANUC. Les résultats préliminaires démontrent qu’il est possible de générer des gouttelettes d’aluminium de manière contrôlée en pulsant le débit d’argon grâce à une valve. Les gouttelettes sont générées à chaque pulse puis sont projetées sur un substrat en suivant une trajectoire précise. L’accumulation des gouttelettes formera une couche d’aluminium, puis les couches seront empilées pour former une pièce. Des pièces en aluminium ont été mises en forme grâce à ce nouveau procédé de fabrication additive. Le volume des pièces pouvant être imprimées est limité par la perte d’efficacité du système de chauffage par induction après plusieurs minutes d’utilisation. La densité apparente la plus élevée obtenue avec ce système est de 84%.
Current metal additive manufacturing machines are expensive and generally unproductive. In addition, the majority of parts from additive manufacturing must be machined after printing to achieve good geometric tolerances. The objective of this research project is to develop a hybrid additive manufacturing system that can replace traditional machining machines. Hybrid systems combine the benefits of additive manufacturing and machining into a single system. This thesis presents the development and usage of a hybrid additive manufacturing system that can form aluminum parts from a Al4043 filament. The system presented in this thesis uses an innovative technology that is based on the principle of induction heating. The filament is melted directly by induction inside a tube, then a flow of argon allows the molten aluminum to eject from the tube. This method makes aluminum preforms that can be machined to obtain a final piece. With this technology, it could be possible to manufacture a hybrid machine at low cost while having a high deposition rate. The system was installed on a FANUC robotic arm. Preliminary results demonstrate that it is possible to generate aluminum droplets in a controlled manner by pulsing the argon flow through a valve. The droplets are generated at each pulse and are projected onto a substrate along a precise trajectory. The accumulation of droplets will form a layer of aluminum, then the layers will be stacked to form a part. Aluminum parts have been shaped by this new additive manufacturing process. The volume of parts that can be printed is limited by the loss of efficiency of the induction heating system after several minutes of use. The highest bulk density obtained with this system is 84%.

Повний текст джерелаThe aim of this thesis is to analyze the factors that determine the conditions of access to the labor market for individuals who arrive in France through the asylum system – whom I refer to as “governed by asylum”. I explore the economic trajectories of these immigrants often framed as political. Drawing on a critical dialogue with the concept of “modes of incorporation”, the first chapters take a historical perspective in order to trace the differential modes of economic incorporation of refugees in France from the 1920s to the 2010s, which both structure and are structured by various social relations of domination. Using a combination of archival materials from government agencies and charities, I retrace the development of a specific system for employing refugees and its fragmentation from the 1980s onwards. In each historical configuration, I analyze the interactions between individuals and organizations within the bureaucratic subfield of refugee management : administrations, nonprofit organizations and members of the field of refugee advocacy, as well as economic actors. The specific nature of the process of refugee labor market integration is to be found in the various rights acquired, in concrete arrangements or in specific modes of mobility control (camps and accommodation centers). Based on fieldwork conducted at the French Interior Ministry and interviews carried out in 2020 and 2021 with actors from the nonprofit, public and private sectors, I then focus on the public policy concerning the “professional integration of refugees” introduced from 2015 onwards. I examine the policy’s contentious origin in light of divisions within the administrative field and demonstrate how the involvement of various private actors influences the discursive framing of refugee employment, the organization of public action and the structure of the nonprofit organizations field. I also analyze how nonprofits, acting as intermediaries in refugee employment and caught between state and market pressures, produce a simplified version of the French language proficiency among refugees and downgraded professional qualifications. Finally, based on a statistical analysis of the ELIPA 2 survey as well as interviews with exiles, I aim to scrutinize the employment status and trajectories of refugees at the end of the 2010s by combining qualitative and quantitative methods from an intersectional point of view. Across different periods and different methods, I propose to consider the employment of refugees and asylum seekers in France as a result of differential modes of economic incorporation. While the material and legal conditions of refugees generally restrict their labor power to the subordinate jobs of the productive system – reinforcing a classist, gendered and racial division of labor – certain groups and individuals manage to be somewhat less governed than others, countering institutional constraints through collective or individual resources

Повний текст джерелаA fundamental route for the exploration of solid state based quantum information is the generation of EPR pairs of quantum-entangled objects. Although experimental tests of nonlocality have been successfully conducted with pair of entangled photons, it has not yet been possible to realize an electronic analogue of it in the solid state, where fermions are the natural quantum objects. However, Cooper pairs in superconductors are known as suitable sources of entanglement. Non-local entanglement is the key and Crossed Andreev reflection process can provide it by converting a Cooper pair into two spin-entangled electrons located in separate conductors.I investigated a device where three superconducting (Al) electrodes are connected by a sub-micron normal metal (Cu) composing a Josephson three-junction. In this hybrid nanostructure, new sub-gap features appear in the differential conductance when two terminals are biased at opposite voltage with respect to the third one. These features correspond to correlated motion of Cooper pairs and are consistent with the prediction of Quartets formed by the simultaneous splitting of two Cooper pairs from one of the superconducting reservoirs and the emission of two phase correlated Cooper pairs in the two other electrodes. In order to probe the quantum coherence of such features, I irradiated the device with a microwave at 14 GHz down to very low temperature (100 mK). Well known Shapiros resonances (both integer and half-integer) are observed when the microwave frequency matches the frequency of the AC Josephson currents generated by applying differents voltages across the three-junction.My study reveals that the quartet feature also shows Shapiro-like resonances. This result demonstrates that the quartet feature is a true quantum mechanism and confirms the quartet scenario that implies the coherent splitting of two Cooper pairs

The working time patterns constitute a major purpose, if not to say central, element in employment policies toward bringing flexibility in the organisation of work and working time. Heteronomy related to the working time shows a recent diversification in the individual and collective duration of work related to the stacking of the devices regarding working time. We consider the selected methods of organization of the working time, by questionning the remaining of the labour division and the effects of reorganizations of work an on its evolution, specially in connection with the consequences related to the working conditions. It suggests that the 35-hours week is an opportunity to introduce new methods in managing the labour force

Повний текст джерелаThis thesis has for objective the writing of a data-processing code allowing the determination of the electromagnetic field in a Reverberation Chamber (RC), using harmonic mode. The principal difficulty in this project is the quantity of useful data-processing resources, especially in the used frequencies range. The developed method is a hybridization using the FDFD/Waveguide mode expansion. The interest of hybridization is to net only part of the interior zone of the enclosure. In the diffraction zone, the finite difference in frequency domain (FDFD) is applied, whereas the electromagnetic field is expanded on a basis of functions in the measurement zone. We define a scalar product utilizing only the longitudinal component of the field, in a cross-section of the cavity. We show that the basic functions then define an orthogonal basis. The originality lies in obtaining the basic functions by numerical calculation (in opposition to analytical), in cases of section of an unspecified form. The validations are carried out by comparison with the analytical ones (without stirrer) and by rebuilding of field cartographies, this for enclosures with rectangular and circular section. The carried out code makes it possible to obtain the weights of the various modes. When the stirrer is present, the validation is statistical and we confirm the laws followed by the various rectangular components and the modules of the field. We note the fundamental role of the losses, defined by the quality factor of the CR for the statistical laws verification

Повний текст джерелаThe objective of this thesis is to incorporate aspects of psychology and behavioral economics theories in discrete choice models to promote a better understanding of mode choice at regional level. Part II examines the inclusion of latent variables to explain mode choice. A literature review of integrated choice and latent variable models – that is, models combining a structural equation model and a discrete choice model – is followed by the estimation of an integrated choice and latent variable model to show how the heterogeneity of economic outputs (here, value of time) can be explained with latent variables (here, perceived comfort in public transport) and observable variables (here, the guarantee of a seat). The simulation of scenarios shows, however, that the economic gain (decrease in value of time) is higher when policies address tangible factors than when they address latent factors. On the basis of a mediation model, the estimation of a structural equation model furthermore implies that the influence of environmental concern on mode choice habits is partially mediated by the indirect utility derived frompublic transport use. Part III examines two utility formulations taken from behavioral economics: 1) rankdependent utility to model risky choices, and 2) reference-dependent utility. Firstly, a rank-dependent utility model is included in discrete choice models and, in particular, a latent-class model, in order to analyze intra- and inter-individual heterogeneity when the travel time is subject to variability. The results show that the probability of a delay is over-estimated for train travel and under-estimated for car travel, especially for car users, as train users are more likely to take into account the expected travel time. In the models that account for risk aversion, the utility functions are convex, which implies a decrease in value of time. Secondly, a new family of discrete choice models generalizing the multinomial logit model, the reference models, is estimated. On my data, these models allow for a better selection of explanatory variables than the multinomial logit model and a more robust estimation of economic outputs, particularly in cases of high unobserved heterogeneity. The economic formulation of reference models shows thatthe best empirical models are also more compatible with Tversky et Kahneman’s reference-dependent model

Повний текст джерелаThis thesis falls within the pillar of energy efficiency. The work presented in this manuscript is to make a modest contribution to the vast body of research on energy efficiency, focusing on the utilization of heat sources at temperatures below 250°C. These sources are referred as "low-to-medium temperature" heat sources, in reference to their limited exploitability in industry. Since the energy from these waste heat sources is often unusable directly, its conversion appears to be an interesting prospect for generating a useful effect that can be injected on-site or into a nearby energy network. The proposed and examined thermodynamic process in this research enable the conversion of low-to-medium temperature heat into two useful effects: cold (at low temperatures) and electricity, with a storage functionality of the heat source in the form of chemical potential. This so-called "hybrid" process is designed based on the integration of a work extraction machine called “volumetric expander” into a thermochemical cycle which exploits a reversible chemical reaction between a solid and a gas (in a reactor) to produce cold from a low-to-medium temperature heat source. The storage functionality in the cycle allows for the separation of the heat source availability phase from the phase of cogenerating useful effects (cold and electricity). This property is extremely advantageous because the timing of the resource and the demand can be very different. A state of the art is conducted to specifically position hybrid thermodynamic cycles involving a sorption process within the context of low-to-medium temperature heat source valorization. After reviewing existing resources (notably industrial heat waste) and the potential for heat storage, the chapter introduces current systems that generate electricity and/or cold from low-temperature heat sources, placing the discussion within the context of existing technical solutions. It highlights the research on “hybrid sorption cycles” and identifies the experimental gaps in their examination. The hybrid thermochemical prototype developed at PROMES (to achieve the proof of concept) is then presented. The first examinations on the cycle are presented. After the concept proof by producing simultaneously cold and stable mechanical power, the effect of cold temperature is studied on the dynamics of the cycle and on its cogeneration. Analytical analysis of the coupling is done too. After, numerical and experimental analyses of the hybrid cycle are done. The effect of the electrical charge coupled to the generator at the expander is studied. The dynamics of the cycle and its cogeneration are analyzed experimentally for different coupled electrical load. Main limitations affecting the production in the cycle are highlighted. The numerical model in steady state is validated, and a sensitivity study on the limiting parameters is done. Detailed numerical work on the cycle is performed. The dynamic energetic model (based on the 1st law) is set under validation with the experimental results, by identifying and adapting its parameters with the ones of the prototype. After, an exergetic model is developed. Exergy destructions in the cycle are calculated, by estimating the irreversibility at each component (based on the 2nd law). Following an exergetic analysis to minimize the exergy destruction during the production phase, the cogeneration performance is improved. Finally, the thesis concludes with a summary of the work undertaken. It outlines perspectives based on this research, including potential developments for the cycle and its components, real-world integration, and new configurations

Повний текст джерелаLes analyses phylogénétiques montrent que la polyandrie est ancestrale au sein du genre Cataglyphis. Le premier axe de ce travail a pour but d’étudier les causes évolutives justifiant le maintien d’un tel système de reproduction au sein de ce genre. Ce travail porte sur les avantages d’une diversité génétique accrue parmi les ouvrières. Une telle diversité génétique permettrait notamment d'accroître le polymorphisme de taille des ouvrières et l'efficacité de la division du travail [Chapitre 1], ou la résistance aux pathogènes de la force ouvrière [Chapitre 2]. [1] Ce premier travail a été réalisé sur Cataglyphis cursor, une espèce strictement monogyne et polyandre. Les résultats de cette étude révèlent une très grande fidélité des ouvrières à la tâche. Ils montrent l’existence d’une association significative entre la tâche réalisée par une ouvrière et sa lignée paternelle, ainsi qu’entre la taille des ouvrières et la tâche effectuée. [2] Le second travail de cette thèse a été réalisé chez C. mauritanica. Nos résultats montrent que la résistance aux pathogènes diffère entre ouvrières issues de différentes lignées paternelles lorsque ces dernières sont isolées. Curieusement, cette différence s’estompe lorsque les lignées paternelles sont regroupées au sein des sociétés polyandres. Dès lors, la polyandrie permettrait d’homogénéiser l’immunité des sociétés. Nos données montrent cependant que la résistance des ouvrières à Metarhizium anisopliae n’est pas corrélée à la diversité génétique de la colonie ou au nombre d’accouplements des reines.
Le second axe de ce travail porte sur les stratégies de reproduction remarquables observées chez les espèces de Cataglyphis appartenant au groupe altisquamis :C. velox, C. mauritanica, C. humeya et C. hispanica. Ces espèces partagent une stratégie unique dans le règne animal, appelée hybridogénèse sociale. L’hybridogénèse classique est un système reproductif dans lequel les parents issus de lignées génétiques distinctes s’hybrident. Alors que les génomes maternels et paternels sont exprimés dans la lignée somatique des descendants, le génome paternel est systématiquement écarté de la lignée germinale. En conséquence, seul le génome maternel est transmis aux générations futures. Dans le schéma d’hybridogénèse sociale reporté dans ces travaux, les reines s’accouplent systématiquement avec un mâle originaire d’une lignée génétique distincte. Elles utilisent la reproduction sexuée pour la production d’une caste ouvrière stérile intégralement hybride (analogue à la lignée somatique) et la reproduction asexuée par parthénogénèse pour la production des castes reproductrices mâles et femelles (analogues à la lignée germinale). Dans ce système, bien que les génomes paternels et maternels soient exprimés dans la caste ouvrière, seul le génome maternel est transmis aux descendants reproducteurs [Chapitre 3]. Le groupe altisquamis est représenté par plusieurs espèces au sein desquelles deux lignées génétiques s’hybrident systématiquement pour la production de la caste ouvrière. Le dernier chapitre de cette thèse [4] est une analyse phylogéographique des espèces de ce groupe dans la péninsule ibérique. Les résultats confirment l’existence d’une seule paire de lignées génétiques au sein de chaque espèce. Ces résultats révèlent également une contradiction entre les marqueurs nucléaires et mitochondriaux traduisant la complexité du système reproductif. Ces travaux soulignent l’ambiguïté des relations phylogéniques entre espèces d’un tel système et discutent de son implication dans la spéciation des espèces hybridogénétiques.
Social insects represent the most extreme form of cooperative life in the animal kingdom. This is based on the existence of a division of reproductive activities between the reproductive individuals (queens and males) and a majority of workers performing all logistical tasks at the expense of their own reproduction. In social Hymenoptera, comparative analysis of reproductive strategies reveals that colonies headed by a single mated queen (monogyny/monoandry) is the ancestral structure of colonies. This structure provides a high genetic correlation between the workers and the brood they raise and, therefore, their overall reproductive success (inclusive fitness). However, an increasing number of genetic studies reveal that the reproductive structure of colonies can strongly differ from this pattern. This is particularly obvious in ants, which have a very large social polymorphism resulting in a large variability in the number of reproductive females within colonies. The Formicidae are also remarkable for the diversity of their modes of reproduction. This diversity relates to mating frequency (monoandry/polyandry) or conditional use of sexual and asexual reproduction. In some species, new queens are produced by parthenogenesis (they are almost clones of their mothers), while the workers arise from a classical sexual reproduction. By using alternative modes of reproduction for queen and worker castes, queens can increase the transmission rate of their genes to their reproductive female offspring while maintaining genetic diversity in the worker population. This high diversity of social structures and modes of reproduction suggests the occurrence of many selective forces. This thesis aimed at determining environmental and genetic factors responsible for the large social polymorphism and the high diversity of reproductive modes display by Cataglyphis desert ants. This thesis is divided into two main parts.
Phylogenetic analyses show that polyandry is ancestral across the genus Cataglyphis. The first part of this thesis examines the genetic hypothesis to account for the evolution and maintenance of multiple mating by queen in this genus. This work focuses on the benefits of increased genetic diversity among workers. Such genetic diversity may increase the size polymorphism of the worker force and improve efficiency of the division of labor [Chapter 1] or increase pathogen resistance of the colony [Chapter 2]. In Chapter 1, the genetic hypothesis to enhance efficiency of division of labor was tested on Cataglyphis cursor, a strictly monogynous and polyandrous species. The results reveal a great fidelity in task performance by workers. They reveal a significant association between patriline and task preference: workers belonging to different patrilines differ in their propensity to perform a given task. We also found that worker size is closely associated with task specialization. The second work of this thesis [Chapter 2] was performed in C. mauritanica. Our results show that resistance to pathogens differs between workers from different patrilines when patrilines are raised separately. Surprisingly, this difference disappears when the patrilines are grouped within polyandrous colonies. Therefore, polyandry would standardize the overall resistance of colonies. Consistent with this result, our data show a positive association between the number of matings by the queens and colony resistance to Metarhizium anisopliae.
The second part of this thesis expounds the unorthodox reproductive strategies observed in species belonging to the group Cataglyphis altisquamis: C. velox, C. mauritanica, C. hispanica and C. humeya. These species share a unique strategy in the animal kingdom, called social hybridogenesis. Hybridogenesis is a sexual reproductive system, whereby parents from different genetic origin hybridize. Both the maternal and paternal genomes are expressed in somatic tissues, but the paternal genome is systematically excluded from the germ line, which is therefore purely maternal. Consequently, only the maternal genome spread across generations. Here, we report a unique case of hybridogenesis at a social level. Queens mate exclusively with males originating from a different genetic lineage than their own to produce hybrid workers, while they use parthenogenesis to produce the male and female reproductive castes. In consequences, all sterile workers (somatic line) are sexually produced hybridogens, whereas sexual forms (germ line) are clonally produced. Thus, only maternal genes are perpetuated across generations [Chapter 3]. The group C. altisquamis is represented by several hybridogenetic species in which two highly divergent genetic lineages co-occur, despite their constant hybridization. The last chapter of this thesis [Chapter 4] is a phylogeographic analysis of C. altisquamis species in the Iberian Peninsula. Our results confirm the existence of a single pair of genetic lineages within each species. Our results also reveal strong incongruences between nuclear and mitochondrial markers that reflect the reproductive system complexities. These studies reveal phylogenetic ambiguities among these hybridogenetic species and discuss the involvement of such unconventional system in speciation process.

Повний текст джерелаThe competences to cooperate/collaborate are amongst the first to be developed in many educational frameworks. Within digitized societies, they promise efficiency, innovation, and well-being at work. However, these competences are not put forward in profesionnal organisations, and they are lacking from adult training courses.Based on this observation, this thesis aims at identifying the competences to be developed to work more easily with others. Bringing light on the abilities to act, convienently called “collaborative competences”, and on the way which they can be developed through training are the objects of this study.Thoroughly analysing the context of a hybrid training is carried out based on the study of the profesionnal trainingcourse “Animacoop: animating a collaborative project” which concerned 200 interns from 2010 to 2014. In this study, collaborative competences are analysed in link with profesionnal experiences and collaborative projects.Falling within an empirical approach, the research methodology connects a few data collecting tools (questionaires, interviews, observations) and on a conceptual level mobilises the Activity Theory and the notion of Training System .This research offers a model of key competences to lead a collaborative project. It analyzes the training system as a strong internally coherent ecosystem, open to development, prone to creativity, which favors collaborate competences development

Повний текст джерелаThis thesis examines the paths and practices of digital artists navigating within the multimedia sectors of Montreal. Through the study of the paths of eleven digital artists based in Montreal we found that production practices in digital arts cannot be reduced to the logic of production specific to a single place, whether a private company, a digital arts center or a university. The issue of maintaining these practices leads one to pay attention to the plurality of elements that inform their perpetual (re)constitutions. This requires new ways of theorizing digital artists' paths and practices. We propose a new way of conceptualizing these paths - as trajectories - to highlight the plurality of ways the digital art practices are articulated. They are thus considered in terms of their co-constitutive mediations with different elements. We have identified three sets of elements to account for the maintenance of the practices in digital arts and through which these unfold their multiple effectivities. The first set covers the technologies involved in digital art practices. The second set relates to the digital arts community and the organizational modes characteristic of those locales. Finally, the third set deals with the relationship between the worlds of business and practices in digital arts. These three sets of elements contribute in various ways to the establishment, maintenance and singularity of digital arts practices that deploy their effectivities far beyond a circumscribed or specialized social space.
