Exploring religious identity negotiation through consumption in secular context : the case of French-Maghreb women living in France by Ranam Alkayyali( )

1 edition published in 2015 in English and held by 2 WorldCat member libraries worldwide

The integration of migrants into Western societies is increasingly becoming a political issue. In this research, we explore how Maghreb women living in France negotiate their religious identity through shopping and consumption. In particular, we focus on how first and second generations of immigrant women who have varying levels of religiosity negotiate their religious identity in the secular context. Interviews were conducted with thirty-six women in Paris (some being two generations within the same family) to explore their acculturation and inter-generational relationships in regards to Islam and consumption. First and second generations of Muslim Maghreb women use products and retail outlets choice from both Muslim Maghreb culture (the brought back heaven) and French culture (the pseudo heaven) inorder to create different identity positions that make their religiosity a chameleon/ serpentine one. We also identify the rule of French market (traditional and modern retailing) -among other factors- in fabricating Muslim Maghreb women identities. Within mother-daughter dyads, a number of inter-generational lifestyle tensions manifesting through consumption emerged indicating the need to separate religion as a determinant of identity
Coproduire le nouveau. Sociologie des plateformes de co-innovation by Emile Gayoso( )

1 edition published in 2015 in French and held by 2 WorldCat member libraries worldwide

Innovation platforms are online disposistifs that companies have started to develop in the middle of the 2000s, in the wake of the Web 2.0, in order to incorporate customers to the innovation process. Presented as new open and collaborative spaces, entirely dedicated to the cooperation with Internet users, these participative processes arouse the enthusiasm of managers and consulting firms specialized in innovation. Yet, there are only few studies dealing with co-innovation that have dedicated a field survey to the dispositifs that have been set up and to the collaborations they host. Sociology, in particular, has had little interest -- in favour of management sciences -- in co-innovation processes involving big companies, and has focussed the most of its analyzes on cases of bottom-up innovation, free software movement and start-up economy.This thesis, by choosing as field survey six platforms built by very large companies from several business sectors (telecommunications, passenger transport and computer equipment), aims to fill this gap.Beyond this ambition that tries to restore the legitimacy of a research topic within a research area, this thesis weaves a reflection on three fundamental problems : why and how do companies associate users to their innovation process ? Why and how do users collaborate with them, most of the time on a volunteer basis ? What new forms of collaboration, nay of relationships, between the individual and the company this sociotechnical dispositifs do carry ?We provide answers to these questions by mobilizing the combined tools of Flichy's theory of reference frame, Thevenot's theory --continued by Auray -- of engagement regimes, and finally the standard concepts of social network analysis (SNA). Empirically, this thesis is based on a field survey conducted since 2010 among the actors of these platforms, in which we have adopted a quali-quantitative method hinging 44 semi-structured interviews with platforms actors (users but also platforms managers, product managers, community managers, etc), online observations and online collaborations network analysis
Au fondement de la relation thérapeutique : l'humilité by Guillaume Monod( )

1 edition published in 2015 in French and held by 2 WorldCat member libraries worldwide

During the therapeutic relationship wich brings together the doctor and the patient, it sometimes occur that the doctor considers the patient to be cured, though the patient does not feel so, or, on the contrary, that the patient considers to be cured even though the doctor thinks the opposite. This paradoxical situation is what can be called the antinomy of the therapeutic relationship. It is the consequence of the fact that healing is not returning to the state of health prior to the illness, but is the implementation of a new norm of life, process named normativity by Georges Canguilhem.Solving the antinomy of the therapeutic relationship requires to put normativity at the center of this relationship, and humility makes this process possible.Humility is a too often held under suspicion, frequently reduced to a form of mysticism or considered as self-deprecation. A critical examination of humility refutes such a commonly-held opinion. Humility, wich seems excluded from the hippocratical corpus and the philosophy of medicine inherited from ancient Greece, is an intelectual and moral virtue, wich hides behind Socrate's maieutic and Aristotle's ethic. Immanuel Kant's Critique of judgement shows that humility is also a scheme wich allows man an opening of his being and wich reveals to him that illness is a trial of life wich is similar to the sublime.A examination of several clinical cases shows that humility, taken as maxim of action of medical practice, is able to solve the antinomy of therapeutic relationship
Économie informelle et les politiques d'emploi en Algérie : quel impact ? by Ali Souag( )

1 edition published in 2018 in French and held by 2 WorldCat member libraries worldwide

Cette thèse porte principalement sur l'impact des politiques d'emploi sur l'économie informelle en Algérie. Dans le premier chapitre, nous tentons de faire le point sur les problèmes de définitions et de mesures quantitatives de l'économie informelle en essayant d'établir un cadre d'analyse standardisé permettant de réduire les conflits méthodologiques. Dans le deuxième et le troisième chapitre, nous estimons le poids réel du secteur informel et de l'emploi informel sur le marché du travail. Nous décrivons aussi les personnes qui travaillent de manière informelle. Dans le quatrième chapitre nous étudions leurs motivations et les raisons d'être de ce type d'emploi. C'est-à-dire nous chercherons à savoir s'ils relèvent d'un processus d'exclusion sociale ou bien d'un choix délibéré. Nous nous interrogeons aussi sur l'hétérogénéité de ces emplois. Dans les deux derniers chapitres nous cherchons à savoir dans quelle mesure les politiques d'emploi en Algérie ont contribué à la réduction de l'économie informelle et le chômage en Algérie respectivement. À la lumière des résultats obtenus précédemment mais aussi sur la base d'autres expériences, nous testons des mesures de politique économique. Pour réaliser cette analyse, nous exploitons les micro-données des enquêtes emplois auprès des ménages menées par l'Office National des Statistiques (ONS) entre 1997 et 2013
La privatisation modifie-t elle la gouvernance de l'entreprise? L'exemple du secteur pétrolier (ENI) en Italie by Ciro Paoletti( )

1 edition published in 2015 in French and held by 2 WorldCat member libraries worldwide

L'ENI - Ente Nazionale Idrocarburi - est un des plus grands groupes pétroliers au monde et un des plus grands groupes entrepreneuriaux d'Italie ; ancien groupe public, privatisé depuis 15 ans, il est un bon cas d'étude pour donner une réponse à la question posée par le titre : La privatisation d'une entreprise modifie-t-elle la gouvernance?La réponse est complexe et est rendue plus difficile du fait des problèmes et des faits qui se sont passés pendant les années et qui ont été exposées dans la thèse. On avait beaucoup de questions préalables à considérer avant de comprendre si la gestion avait-elle modifié par la privatisation et si avait-elle eu du succès ou non. Avant tout quelle était la période à prendre en considération ?Il était nécessaire de regarder toute la période depuis l'aboutissement de la privatisation jusqu'à nos jours, car c'était la seule manière de comprendre. Et on avait encore une raison liée au domaine pétrolier pour regarder à la période la plus longue : on a parfois besoin de 15 à 20 ans pour voir les résultats d'un investissement tel que l'exploitation d'un gisement : donc on ne pouvait pas se limiter à une courte période, mais toute la période à disposition.Enfin il y avait encore un autre problème : le rôle des actionnaires. Leur activité avait-elle appuyé une politique destinée à obtenir des gains et à éviter des pertes dans le groupe ENI ? Le groupe a-t-il vraiment été capable d'obtenir toujours le maximum et, si non, quel a été le rôle de ses actionnaires, ou mieux, le rôle du plus important de ses actionnaires, qui est encore l'Etat italien ? Et ce rôle est-il expliqué de quelle manière ? A-t-il optimisé les résultats entrepreneuriaux ou non et, le cas échéant, a-t il permis au groupe d'atteindre ces résultats d'optimisation, de baisse de prix et d'amélioration du produit et du service au client qui, selon les théoriciens, devraient être le but et à la fois le résultat d'une privatisation ?
L'impact de la spécialisation sur la stabilité économique : le cas des pays émergents. by Ons Abbes( )

1 edition published in 2017 in French and held by 2 WorldCat member libraries worldwide

The fast growth of the world trade during the last two decades was characterized by an improved performance as well as an economic instability of emerging countries. According to the literature, the technological specialization is often associated with growth, competitiveness and economic stability. Recognizing this, we analyze the impact of the specialization of emerging countries on their growth and on their economic stability and we estimate the impact of the competitiveness (itself related to specialization) of these countries on their export performance.In a first chapter, we outline the contours of the notion of specialization according to the various theories.Having determined as objectively as possible a list of emerging countries referring to the most criteria used in the literature and having measured the degree of specialization of these countries, we study the map of the technological specialization in emerging countries over the 1995-2014 period. According to this cartography, we notice a bad orientation of their specialization. These countries are essentially characterized by a strong specialization in Labour-intensive and resource-intensive manufactures and low-tech items that are low value-added specialization. The specializing in high technology is largely driven by imports. Exports are mainly drawn by assembly activities.In the second chapter, we first assess the impact of technological specializations of emerging countries on their economic growth and we compare the results with those found in the developed and developing countries. We find that different types of specialization have a positive impact on the growth of emerging countries. But this positive impact cannot hide the misdirection of this specialization (result of Chapter 1).Second, we study the impact of competitiveness (price- and non-price competitiveness) of emerging countries on the development of their exports. We note that the impact of price-competitiveness on the evolution of the exports of the countries in our sample depends on the indicator used. It is negative when we use the exchange rate and positive when we use productivity.We also find that the impact of the structural competitiveness, measured by the expenses in the high technology and by the specialization in the high technology, is positive. It can be explained by the more and more increasing world demand in the high-technology products.In the last chapter, we focus on the relationship between specialization and economic stability and we compare this relationship with that observed in developed countries. We find that countries whose specialization is based on natural resources are more unstable and that the impact of specialization in high technology depends on the country's level of development. The impact is negative for developed countries and positive for emerging countries. This difference in the impact may be due to the assembling policy used by most emerging countries and which leads to import of high-tech products (HT) as parts and components
Économie informelle en Haïti, marché du travail et pauvreté : analyses quantitatives by Roseman Aspilaire( )

1 edition published in 2017 in French and held by 2 WorldCat member libraries worldwide

The predominance of the informal sector in the economy of Haiti, where more than 80% of the population lives below the threshold of poverty and more than 35% unemployed, suggests links between the informal economy, poverty and the labour market. Highlight these interrelationships, requires an assessment of the informal economy, which is the subject of the four chapters of this thesis, dealing successively with the evolution of the macroeconomic situation, human capital, the informal earnings of workers, and the segmentation of the labour market.The first chapter made a diagnosis of the phenomenon according to the State of affairs of the developed theories and the evolution of the macroeconomic framework of Haiti from 1980 to 2010. And then offers a macroeconomic assessment of the informal sector as a percentage of GDP from a PLS (Partial Least Squares).Chapter two sets out the relationship between the evolution of the informal economy, deregulation and neo-liberal policies through a LISREL (Linear Structural Relations) model. We look at the impact of the budgetary, fiscal and monetary policies of the past 30 years on the informal economy. We also reassess the causes of the evolution of the informal economy generally evoked by the empirical studies (taxes, social security).In the chapter three, we analyse the micro-real dimension of the informal economy through a model of the Mincer earnings estimated by the equations logit from data in a national survey on employment and the informal economy (EEEI) in 2007. We analyse the determinants of informal gains in terms of the position of the market workers (employees, entrepreneurs and self-employed); and revenues (formal and informal) and the socio-economic characteristics of the working poor and non-poor compared to the poverty line.In chapter four, we first test the competitiveness and the segmentation of the labour market by making use of model of Roy and the expanded Roy model through an estimate a model Tobit. We use a model of Dirichlet process: first analyse the segmentation and possible informal work and market competitiveness as its determinants, according to data from the EEEI 2007; then, to distinguish the fundamental characteristics of the involuntary informal (excluded from the formal labour market) than the voluntary informal who gain comparative advantages
La résilience dans l'humanitaire, un concept pour penser autrement la gouvernance des catastrophes socio-climatiques by Camille Raillon( )

1 edition published in 2017 in French and held by 2 WorldCat member libraries worldwide

Resilience in humanitarian. A concept to think differently about the governance of socio-climate disasters.The concept of resilience integrates the humanitarian space in the early 21st century. Its starting point is the ambition of the NGOs to improve the impact of their activities on the most vulnerables populations. If the concept of resilience was born in the physical sciences, its integration in the mid 20th century in multiple research areas: environment, economy, psychology and politics, endows it today with various interpretations and definitions. Through its multiple roots, this integration is by deduction, limited by the complexity to find a definition, indicators and adequate methodology to measure and therefore improve assistance to victims. By focusing on managing socio-climate disasters, namely those related to human activities on ecosystems and extreme climate events, we have chosen to question the meaning and scope of this concept in humanitarian. In other words, the side of its theoretical aspects, how to understand resilience to think differently about the governance of socio-climate disasters?We put forward the idea that resilience is a concept. In the sense that resilience is a general idea that helps to organize knowledge on multiple and complex rebounds capacity of an entity following a shock. Our study in 2014 on the evolution of life histories of 144 homes in the Delta of the Sundarbans in Southern Bangladesh highlights a typology of different capacities following the cyclones Sidr 2007 and Aila 2009. Furthermore, our results argue the idea that if resilience is an endogenous capacity, it interacts with two additional terms and controversies that have integrated the humanitarian space between the middle and late 20th century: the vulnerability and adaptation of societies. We argue that if these three terms are severable and sometimes contradictory, their overlapping enables a more detailed analysis of issues and local socio-ecological dynamics. This allows us to point out our first hypothesis: the concept of resilience is apprehended in humanitarian as an integrating concept serving a systemic approach to disasters governance.Finally, we defend that resilience can also be seen as a systemic approach that challenges the humanitarian model. Since it is not only taking inspiration from the classical model like planning, development, and quality control to answer to disasters, but to be able to model the confusion and conflicting perceptions of the crisis and risks. The integration of resilience contributes to a modeling aid, based on functional, structural and historical aspects of the organization with a more integrated vision of the socio-ecological systems.Through many controversies that cross the idea of resilience, we are witnessing, if this is not a profound change of paradigm in humanitarian, to an enrichment of the thought on governance of disasters, and the models of helps that goes with them. Therefore we ask our research question, how the concept of resilience is apprehended in humanitarian to a systemic approach and innovative models of assistance that emphasize an integrated relationship society-environment?
La résistance socialement responsable à la consommation : proposition de conceptualisation et implications pour les pratiques du marketing by Mouna Benhallam( )

1 edition published in 2016 in French and held by 2 WorldCat member libraries worldwide

This research focuses on protest movements towards market system and its devices, having for main motive the social and environmental concerns. This work aims at underlining the existence of the socially responsible resistance (SRR) and therefore its interest, considering its uniqueness and the managerial challenges that it implies. Through an observational netnography approach using an interpretativist method for data analysis, the research is based on a study of three virtual different communities'representative of the investigated phenomenon and leads to two major results. On the first hand, the research end in an understanding conceptualization of the phenomenon, stressing its initiator factors, caracteristics, but also the SRR wide range of expression forms. On the other hand, this work emphasizes evolution and reform perspectives of marketing practices, methods and strategies
Quelle est l'efficacité des pratiques managériales d'empowerment des consommateurs? : le rôle des caractéristiques du profil des consommateurs et de la familiarité de la marque by Hajer Bachouche( )

1 edition published in 2017 in French and held by 2 WorldCat member libraries worldwide

L'empowerment du consommateur/client est une pratique mobilisée de manière croissante par les entreprises comme dans les travaux académiques depuis plus d'une dizaine d'années. Deux types de stratégies d'empowerment ont été distingués par la littérature : l'empowerment pour créer qui permet aux clients de soumettre des idées pour les nouveaux produits et l'empowerment pour sélectionner qui s'appuie sur les votes des consommateurs pour le choix des produits qui seront in fine commercialisés (Fuchs et Schreier, 2010). Se basant sur l'approche de l'empowerment du consommateur en tant que stratégie managériale collaborative entre consommateurs et entreprises dans le cadre du développement de nouveaux produits, cette recherche vise à en évaluer les effets sur les indicateurs liés à la marque pour les consommateurs participants. En vue de répondre à cette problématique, une étude qualitative (menée auprès de consommateurs et de managers) suivie de trois études expérimentales (N=719) structurent ce travail doctoral. A l'aide d'une approche pluridisciplinaire (politique, sociologie, psychologie), une conceptualisation de l'empowerment des consommateurs est réalisée ainsi qu'une distinction de ce concept des autres formes de co-innovation. Les résultats obtenus montrent que le recours aux stratégies d'empowerment est plus bénéfique pour les marques à faible familiarité perçue (start-ups) en comparaison à des marques familières (réplication sur deux catégories de produit). Aussi, cette recherche révèle que l'empowerment pour créer améliore plus efficacement le bouche à oreille et l'engagement à l'égard de la marque que l'empowerment pour sélectionner. Le rôle de plusieurs facteurs d'ordre individuel et situationnel dont l'expertise perçue à l'égard de la catégorie de produit, les bénéfices perçus par les participants, le type de motivation et l'effet de récompense (gain vs. perte) ont pu être identifiés. Ainsi, les résultats de notre travail doctoral démontrent notamment que le gain du challenge d'innovation (vs. la perte) n'améliore pas significativement les indicateurs liés à la marque étudiés. Des préconisations managériales sont suggérées pour une meilleure prise en compte des caractéristiques du profil des contributeurs et celles liées au design des challenges d'innovation cruciaux pour le déploiement de stratégies d'empowerment efficaces
Towards a better integration of the informal sector : three empirical essays on the interaction between formal and informal firms in Egypt and beyond by Nesma Mohamed Ali( )

1 edition published in 2017 in English and held by 2 WorldCat member libraries worldwide

Depuis les années 2000, les économies du continent africain ont fait preuve de remarquable croissance. Toutefois, le contexte actuel met en péril le développement durable du secteur privé. Les imperfections liées au système institutionnel et à l'environnement commercial entravent l'évolution stable des entreprises et ouvrent la voie à la croissance d'un secteur informel très persistant. Cette thèse ouvre à nouveau le débat polémique sur le secteur informel en soulignant la capacité entrepreneuriale de ce secteur plutôt que les menaces qu'il représente. Afin de comprendre la forte persistance de l'informalité en dépit de ses impacts négatifs, nous testons à quel point la concurrence entre firmes formelles et informelles pourrait affecter l'économie égyptienne. Nous constatons qu'une concurrence plus intense incite les entreprises formelles à devenir plus productives. Nous étendons également notre analyse aux pays d'Afrique subsaharienne en soulignant l'effet stimulateur de la taxation et de la réglementation sur la puissance de la concurrence entre les entreprises formelles et informelles. Nos résultats font appel à l'introduction du secteur informel dans les politiques publiques visant la réforme de la fiscalité et de la réglementation en Afrique. Ces politiques devraient également viser l'accès des entreprises aux sources de financement, d'infrastructure et de formations comme outils principaux induisant le processus de formalisation et favorisant la croissance économique. Cette thèse souligne l'importance de repenser les effets du secteur informel dans les pays en développement, tout en le considérant comme un stimulateur de croissance économique plutôt qu'une menace
L'UNASUR : la nouvelle voie d'intégration régionale sud-américaine sous l'hégémonie du Brésil by Jaime Pinto( )

1 edition published in 2016 in French and held by 2 WorldCat member libraries worldwide

Dans un contexte international où la faiblesse relative de la superpuissance américaine a permis l'émergence de nouveaux acteurs étatiques qui commencent à modifier l'ordre mondial occidental, les processus d'intégration comme ceux d'Amérique du Sud peuvent être interprétés comme un moyen d'acquérir l'autonomie face aux puissances du monde. Mais jusqu'à présent les efforts des pays pour s'intégrer ont été infructueux. Les divergences entre gouvernements de la région et l'inexistence d'une véritable volonté politique de cession de souveraineté auprès des organismes supranationaux ont remis en cause la faisabilité d'organismes existants comme le Mercosur ou la Communauté Andine. Cependant, malgré plusieurs échecs d'essais d'intégration régionale en Amérique Latine, le pouvoir accru des pays émergents dans l'actuel monde unimultipolaire donne la possibilité d'initier un processus de régionalisation sous l'hégémonie du Brésil. L'hégémonie brésilienne est en train de forger une nouvelle configuration géopolitique en Amérique du Sud, par l'intermédiaire institutionnel de l'Unasur. Cet organisme régional est un reflet de la volonté du Brésil de s'insérer de manière complètement autonome dans le système international, créant ainsi progressivement l'un des pôles de puissance qui donneront sa forme au siècle actuel
L'appropriation, les effets et l'évolution des politiques d'égalité professionnelle entre les femmes et les hommes dans les grandes entreprises : combiner les approches qualitative et quantitative pour appréhender ces politiques by Clotilde Coron( )

1 edition published in 2015 in French and held by 2 WorldCat member libraries worldwide

Réalisée dans le cadre d'un contrat CIFRE, cette thèse étudie la construction, l'appropriation et les effets de la politique d'égalité professionnelle entre les femmes et les hommes chez Orange. Mobilisant la perspective appropriative des dispositifs de gestion enrichie par le concept de logiques institutionnelles, ce travail repose sur un matériau riche et varié : entretiens, données RH, séquences d'observation, documents internes, notamment. Nous montrons que la coexistence de plusieurs conceptions de l'égalité professionnelle au sein de l'entreprise structure fortement l'application de la politique au niveau local, mais également sa construction, qu'il s'agisse de l'accord d'entreprise ou de la politique non négociée. L'analyse conjointe de l'application de la politique et de ses effets, permise par la combinaison de matériaux et de méthodes qualitatifs et quantitatifs, nous donne de plus l'opportunité de comprendre les effets quantifiables (ou l'absence d'effets quantifiables) d'une mesure à l'aune de la manière dont elle est appliquée au niveau local. Nous mettons enfin en exergue les spécificités de la négociation sur l'égalité professionnelle par rapport à d'autres négociations, dues notamment à la transversalité de l'égalité professionnelle à de nombreux processus RH ; et nous soulignons l'importance de la coexistence et de l'articulation de l'accord d'entreprise et de la politique non négociée sur l'égalité professionnelle
La mise en oeuvre des sûretés réelles en droit international et européen. L'exemple des navires et aéronefs by Amithisse Monnet( )

1 edition published in 2017 in French and held by 2 WorldCat member libraries worldwide

Ships and aircrafs are valuable assets but their financements are really hard to set up. Unlike most of the goods, ships and aircrafts are linked to a State and are essential for trades. They are submit to special laws which considere their specific nature. Those registrated goods require securites interest which are found on real rights. Thoses securities are différent in each State and they need a judicial execution proceeding to be effective.This study is at the crossroad of different specialities which are needed to allow the efficiency of the real rights. Thoses rights are essential to securite international trade. This study proves that judicial execution proceedings have a role in international trades
Déterminants du commerce international de déchets dangereux et recyclables : analyse économétrique by Esther Amouzou( )

1 edition published in 2017 in French and held by 2 WorldCat member libraries worldwide

This thesis consists of two empirical studies on the analysis of international waste trade determinants, more precisely the hazardous waste on the one hand and the metallic waste on the other hand. Different econometric methods were used on statistical data from Eurostat (for hazardous waste) and UN Comtrade (for recyclable waste). If the literature on the determinants of international trade in waste is scarce and limited, it is because of the absence of a universal definition of waste (due to the plurality of definitions) leading to classification problems, non-matching of waste flows and the absence of a specific database. It is up to the researcher to build his own database from his own definition. We propose, in this thesis, to provide insights on some points which have been too few studied. The first chapter studies the dialectical relationship between waste definition and its related regulations; and focuses on the theoretical aspects of international trade in waste based on those of the international trade in goods. The analysis reveals that waste is a particular good, which makes its trade also particular. Thus, its definitions are superimposed, opposed and / or complement each other. Moreover, the European Union is the pioneer zone in terms of waste policy and waste is highly regulated, especially before its generation (prevention) and from its generation to its final treatment.The second chapter examines the determinants of trade in hazardous waste and asks whether the EU waste policy has succeeded or failed. We find that proximity and differences in waste treatment capacity across countries and in regulations are important determinants of this trade. In particular, countries with high hazardous waste treatment capacities demonstrate increased hazardous waste imports. We also find that these countries have high environmental performance indices. These results imply that EU waste management policy plays an important role in shaping European trade in hazardous waste. Finally, it seems that there is no waste haven effect for the EU hazardous waste trade.The third chapter tests the determinants of international trade in metallic waste, more precisely the assumptions that industrial specialization captured by revealed comparative advantages, virgin material and secondary material prices are important determinants of international trade in metallic waste. We find that industrial specialization is a motivating factor for exports and discouraging for imports. The decision to export or import depends especially on metal and metal scrap price sensitivity. When metal costs more than metallic waste, importing countries specialized in metallurgy prefer to import metallic waste in order to substitute it to the virgin material and / or to preserve the latter. Exporting countries prefer to export metallic waste when its price is in the ascending phase and the price of virgin material is in its downward phase. This, in order to preserve the virgin material and to use the secondary material at its place. In any case, an arbitration is made between the price of the virgin material and the price of the secondary material. Furthermore, the regulation gap plays an important role in arbitration. Metallic wastes are not exported to countries with low environmental performance. Inversely, imports are made from the latter
L'espace public élargi. Opinion, critique et expressivité à l'ère d'internet by Dominique Cardon( )

1 edition published in 2015 in French and held by 2 WorldCat member libraries worldwide

This thesis gathers a series of articles dealing with the ordinary forms of participation in the public space. It attempts to describe the way the public have been led to express itself in traditional media, alternative media and the web. From an approach examining different formats of enunciation (opinion, criticism and testimony), this work intends to understand how public space has expanded to new audiences and new regimes of expression with the appearance of web at the turn of the 2000s. The different researches gathered in this thesis compares (1) case studies on the expression of listeners in traditional radio program (Les auditeurs ont la parole (RTL), Les indignations pour l'abbé Pierre (France Inter) and L'émission de Menie Grégoire (RTL)); (2) analysis of the role of alternative media and the anti-globalization activism in the criticism and the invention of new formats of expression on the Internet; and (3) case studies of new spaces for ordinary expression appeared with the birth of blogs, Wikipedia and social networks of Web 2.0. The opportunity for all to publish on the Internet without going through the filter of traditional media led both to a release of subjectivities and an internalization of expressive constraints by individuals. This analysis also highlights the importance of variation in size and shape of the public in the digital world by showing how to the abstract and anonymous public of traditional media, the web substitutes a dynamic and interactive manufacturing of visibility. In articulating the analysis of digital sociability and the building of public visibility, this thesis shows how the requirements and constraints of the public space are increasingly included in the socialization process of individuals in our societies
Les universités gèrent-elles leurs personnels BIATSS? : l'entretien professionnel comme révélateur des pratiques by Romain Pierronnet( )

1 edition published in 2018 in French and held by 2 WorldCat member libraries worldwide

French universities have undergone recent transformations through reforms inspired by New Public Management. The deployment of a new national budgetary framework (" LOLF ") followed by the LRU law (" Liberté et Responsabilité des Universités ") in 2007 led to the transfer of new responsibilities to universities, including Human Resources Management (HRM): researchers and "professionals" ("BIATSS"). While research work has been devoted to the former, the latter has been studied much less frequently, particularly from the perspective of HRM policies and practices dedicated to them.This research, funded through a CIFRE agreement with Adoc Mètis, aims at understanding the reality of the autonomy of French universities in managing their BIATSS staff. Thus, it takes stock of the effects of the LRU law on this matter, ten years after its adoption. More generally, it can contribute to discussing the reality of public HRM transformations in France, in the light of the model promoted by the reformers: from national and statutory personnel administration practices, the aim is to develop local management based on skills.Conducted within two universities, our research relies on a study of the appraisal interviews conducted by BIATSS staff, at the heart of the desired transformations of public HRM. Our methodology therefore considers appraisal interviewing as a management tool that reveals several HRM processes, linked to the three objectives set out by law: assessment of objectives, management of staff skills and training, and decisions about promotion. Given these aims, we propose to understand the perception and uses of interviewing by staff, both at the local level (within four departments) and at the "central" level (Directorate of Human Resources and promoting committees).Our results first of all question the coherence of appraisal interviews, both internally (lack of consistency of the targets with the assessment methods) and externally (limited integration of the interview with the production of decisions for which specific tools already exist). The interview appears to be a universal clamp of public HRM, which helps explain its sometimes paradoxical and limited effects with regard to its theoretical functions.The analysis of the uses of appraisal interviews suggests that a distinction should be made between several levels, starting with a national level which remains a strong prescriber of university HRM, through its funding to universities and the rules it produces to organize the local management of agents, most of whom are national civil servants. This is the case, for example, with regard to the appraisal interview system itself: while national government intends to develop the autonomy of universities, it is generalizing a system for the appraisal of staff, embedded in procedures and processes for the management of staff stemming from national rules specific to civil servants' bodies.At the local level, both institutions have few specific HRM policies and practices, including the management of their contractual staff. This observation is the result of both internal political resistance and the complex ways in which decisions are produced within university organizations, where different logics confront each other. In so doing, the development of local management, co-produced with managers and based on the local appreciation of objectives and skills, comes up against the persistence of an historical conception of the public service
Disentangling occupational and health paths : employment, working conditions and health interactions by Éric Defebvre( )

1 edition published in 2017 in English and held by 2 WorldCat member libraries worldwide

The objective of this Ph.D. Dissertation is to disentangle some of the many interrelationships between work, employment and health, mostly in a longitudinal approach. Establishing causal relationships between these three concepts is not easy, as many statistical biases generally undermine estimates, including selection biases and the three classical sources of endogeneity. This thesis proposes in a first chapter to study the effect of a mental health shock on workers' ability to remain in employment. The second chapter explores the possible sources of heterogeneity in the role of working conditions on health status by examining the effects of variable early-career exposures in terms of intensity and nature on the onset of chronic diseases. Finally, the third chapter deals with the end of the career and the decision to retire. The French panel data from the Health and Professional Path (Sip, Santé et Itinéraire Professionnel) survey with more than 13,000 respondents is used in this work, as well as several methodologies in order to take into account endogeneity biases, in particular methods relying on instrumental variables and methods for public policy evaluation (matching and difference-in-differences). The results confirm that employment, health and work are intimately related, with clear consequences of health shocks on employment and, conversely, a preponderant role of work on the determination of health status
Analyse économique des préjudices et des indemnisations des accidents de la circulation routière : une approche par la victime by Hamza Achit( )

This thesis analyzes the economic consequences of road accidents for the injured victims. We study the impacts in terms of health spending and in terms of sick leave. The analyses rely on an original dataset obtained by a specific extraction from the information system of the French Health Insurance. This information system constitutes an almost exhaustive database of victimsof road accidents.Different descriptive and econometric analyses are conducted. First, we use generalized estimating equations models to analyze the determinants of extra health expenses, and survival models for the analysis of the determinants of economic loss related to a sick leave episode. Secondly, we analyze the evolution of these extra expenses and losses over time by means of agroup-based trajectory model. This method also allowed us to establish a typology of injured victims based on the similarity of long-run outcomes. Finally, to inform the public and decision makers on the costs occasioned for the different types of accident victims we evaluate the averagecausal effect of an accident with the exact matching method

The Thesis aims at evaluating monetary policy in presence of financial frictions both from an empirical and structural perspective. Along those lines, multi-variate time-series framework as well as model with more explicit theoretical foundations will be deployed. The Thesis presents original contributions in various fields of monetary and financial macroeconomics.The main motivation for the applied research presented in this Thesis are twofold. It responded both to the need for deeper research on macro-financial linkages and to the growing interest of policy institutions for the model-based policy advise. First, the Great recession and in particular, the typology of crisis episodes in Europe over the last decade, unveiled new challenges for monetary policy conduct, notably related to the prevalence of financial factors in cyclical fluctuations, the design of non-standard measures and the interactions with financial service policies. The second motivation has to do with the growing role for structural models in the preparation of monetary policy within central banks. Over the last decades, academic research and central bank practices have mutually benefited from strong synergies, whereby quantitative methods and theoretical advances have had a lasting influence on main preparation avenues for monetary policy making.In Chapter 1, a set of empirical studies intend to demonstrate the prevalence of financial shocks underlying the euro area macroeconomic performance during the Great recession. In particular, BVAR models can identify credit supply shocks and quantify their contribution to the various recessionary episodes over the last decade.Thereafter, Chapter 2 explores more structurally the transmission mechanism of financial shocks together with their heterogeneity across the euro area through the lens of DSGE models featuring a relevant set of demand-side as well as supply-side credit frictions.Against this background, the Thesis examine more normative aspects of monetary policy conduct starting with derivation of optimal monetary policy in selected DSGE models, which is the focus of Chapter 3. The Ramsey approach to optimal monetary provides a clear benchmark for formulating normative prescriptions. We analyse the main properties of the Ramsey allocation within a set of quantitative DSGE models, thereby bring new insight on various closed economy and open economy policy challenges.At times of crisis, as financial-driven recessions bring the monetary policy interest rates to their effective lower bound, central bank deployed a set of non-standard measures in order to engineer the intended policy accommodation. Chapter 4 presents several studies which extend DSGE models to analyse the role of non-standard monetary policy measures like asset purchase programmes or long-term liquidity operations. The credit channel of those measures will be the focus of the analysis. From a more normative standpoint, the optimal central bank asset purchase strategy will be derived.Finally, in Chapter 5, the normative assessment of monetary policy conduct in presence of financial frictions calls for considering strategic interactions with other policies, and notably macroprudential policy. Such interactions are all the more relevant when analysed in a monetary union context through multi-country DSGE models
