Texto completoOnce considered as a specimen of distorted convention for failing to achieve its objective of contractual justice the employment contract is now being renovated to meet its former standard as a consequence of the latest evidentiary developments. Within a few decades evidence, which was formerly biased, has been subjected to in-depth transformation in order to restore balanced evidentiary patterns in employment law. The presentation of evidence and the testing of that evidence testify to that trend. While an employee may now better argue his or her grievances an employer may find it more complicated to set up his or her evidentiary arguments. The rediscovery of the concept of loyalty and the progressive recognition of employees'rights are grounds for a betterbalanced system. Moreover, the increased autonomy of evidentiary questioning in employment law has provided the restoration of the notion of balanced evidence. All of this tends to one and the same objective : contractual justice
Mouloungui, Maganga Aimé Roger. "Le particularisme de la preuve en droit du travail". Limoges, 2012. http://www.theses.fr/2012LIMO1004.
Texto completoFort of the imbalance of strengths enter the employee and the employer the contract of employment, the French legislator, widely followed by the judge, began (undertook) of importances transfers (transformations) regarding proofs. The objective being to restore for the benefit of the employee a balance between the parties to the lawsuit that, the initial contractual relation not guaranteed not. So, we observe that the producing of evidence in labor law, from now on remote from a strict application of the rules (rulers), of proof such as planned by the common law, obeys a particular diet (regime). That it is about thorough rules (rulers), or about those who touch the procedure itself, the law posts( shows) an attitude apparently protector of the low (weak) part (party), in particular the employee for whom, it operates a significant reduction (lightening) of its probationary burden, while, at the same time, that of the employer see itself weighed down to the advantage of the employee
Terroux-Sfar, Florence. "Les règles de preuve et les évolutions du droit du travail". Thesis, Paris 10, 2012. http://www.theses.fr/2012PA100037.
Texto completoThe labor law knew during these last thirty years remarkable evolutions with the appearance of new information technologies and communication in the companies and, the creation of “justification’s requirement”. In the mean time employers are now obliged to detail the motivations of their actions and the employees are working more and more on informatics work station. It’s important to understand how these new characteristics have modified the application of the rules of the proof. If the proof’s burden seems to not have been affected by these evolutions, it is not the same about the proof’s object. Indeed, beyond the appearances, the new information and communication technologies lead to a modification of the proof object by giving to the employees the access of new elements of proof susceptible to influence the judge’s conviction. Besides, the “justification’s requirement” invites the judges to better control the employer’s decision. They have now the obligation to clarify their reasons for action. Concretely it means that, to support their claims, they can’t just argue objective facts to convince the judge but they have to justify the logic of their decisions. So, while the classic doctrine had for practice to expect relevant, controversial and questionable facts as proof objects, the “justification’s requirement” brings us to add “sensible facts" (facts articulated within a coherent speech). If at the first time, we could think that the “justification’s requirement” emergence will lead to subjective decision, we are obliged to admit the reinforcement of the judge control

Texto completoIt should be noted that in labor law, the administration of proof, by the employer, is now conditioned by the requirement of fairness of the proof as understood by the Social Chamber of the Court of Cassation. Beyond this observation, a requirement of loyalty which now underlies the practice of proof in labor law, a problem arises, however: This investment in the field of proof law by case law, and this, by means of the requirement of loyalty, does it always make it possible to achieve the emergence of the truth, the feeling of justness which must emerge from the confrontation of the arguments that have left? On the contrary, this consecration of loyalty as the case law has intended to enshrine it, has it not led to a law of evidence that is too rigorous, the application of which no longer allows the emergence of the truth?

Texto completoAny employer’s decision has to meet the requirement of objectivity, implying that his power cannot be arbitrary, i.e. the employer is prohibited to base any decision on his own personal views. Thus, the employer has to base each decision, outside his discretionary power, on provable factual premises. The objectivity test applies to vocationnal assesment, dismissal, and differenciation between employees. However, the objectivity test is ambivalent as some employers exploit this requirement to restrict employees’ fundamental rights in the name of the company’s interests or some other specific interests. This is all the more easy as judges’ control on employer’s objectiveness is rather loose. Therefore, employers’ staff management have to be scrutinisied on some other legal grounds. On the whole the objectivity test has rather a relative importance

Texto completoProcedure in labour contentious matters is the most significant place to observe the judicial reception of e-proof. Pragmatism and flexibility of the elected industrial tribunal offers a field of study which is suitable to observe the axiological confrontation between ICT and labour law and to observe the practicalconsequences of the inclusion of such proof in the litigants’ argumentation. This research endeavours to demonstrate that the use of e-proof receives a mixed appreciation from the Judge of the contract of employment. Indeed, he adopts a paradoxical behaviour: on the one hand, he shows boldness and takes part in the recognition of the e-proof during the phase of producing evidence; but on the other hand, he seems to be reluctant to make use of it in an effective manner. The result of this study is disappointing when considering the credibility given to e-proof is not equal to its procedural utility; it deserves to be the subjectof a more ambitious approach and of a general and more in-depth reflexion
Boudjani, Nadira. "Aide à la construction et l'évaluation des preuves mathématiques déductives par les systèmes d'argumentation". Thesis, Montpellier, 2018. http://www.theses.fr/2018MONTS060/document.
Texto completoLearning deductive proofs is fundamental for mathematics education. Yet, many students have difficulties to understand and write deductive mathematical proofs which has severe consequences for problem solving as highlighted by several studies. According to the recent study of TIMSS (Trends in International Mathematics and Science Study), the level of students in mathematics is falling. students have difficulties to understand mathematics and more precisely to build and structure mathematical proofs.To tackle this problem, several approaches in mathematical didactics have used a social approach in classrooms where students are engaged in a debate and use argumentation in order to build proofs.The term "argumentation" in this context refers to the use of informal discussions in classrooms to allow students to publicly express claims and justify them to build proofs for a given problem. The underlying hypotheses are that argumentation: (i) enhances critical thinking and meta-cognitive skills such as self monitoring and self assessment; (ii) increases student's motivation by social interactions; and (iii) allows learning among students. From instructors' point of view, some difficulties arise with these approaches for assessment. In fact, the evaluation of outcomes -- that includes not only the final proof but also all intermediary steps and aborted attempts -- introduces an important work overhead.In this thesis, we propose a system for constructing and evaluating deductive mathematical proofs. The system has a twofold objective: (i) allow students to build deductive mathematical proofs using structured argumentative debate; (ii) help the instructors to evaluate these proofs and assess all intermediary steps in order to identify misconceptions and provide a constructive feedback to students. The system provides students with a structured framework to debate during construction of proofs using the proposed argumentation frameworks in artificial intelligence. These argumentation frameworks are also used in the analysis of the debate which will be used to represent the result in different forms in order to facilitate the evaluation to the instructors. The system has been implemented and evaluated experimentally by students in the construction of deductive proofs and instructors in the evaluation of these proofs

Texto completoThis research focuses on medical examiners and the reports they provide upon requisition from Public Prosecutors. Neither occasional collaborators of the judge, nor holders of a specific specialty title, forensic scientists and medical examiners form a professional body that is quite distant from both the judicial expert assessment model and the medical specialty model. They mainly practise the medico-legal expertise in dedicated hospital units, and have undergone a medical university curriculum, with medical specialties ranging from general medicine to anatomopathology, and from occupational medicine to public health.This thesis explores the tension between a judicial expert assessment and a medical specialty, and analyses this tension, simultaneously as being enshrined into the formation process of the occupational group, and as a driving force of the coproduction of medical and judicial truths about facts. The research builds on the implementation of an empirical investigation system, associating ethnographic observations, interviews, and documentation. The different locations that were analysed (autopsy rooms, doctors’ offices, Ministerial directions, decentralised administrations, Public Prosecutors’ committee rooms, congress) constitute a two-level analysis of the medico-legal apparatus: on one hand, the protocol level, where medico-legal activities are organised and supervised, from state-level administrations to local departments; on the other hand, the expert assessment level, where medical examiners were studied from medical examination rooms up to courts of law. The first chapter explores the protocol level, by studying, in particular, the genesis, elaboration and implementation of a forensic medicine reform. It highlights how the organisation of medico-legal activities has been oscillating between two definitions of a medico-legal expertise; these two definitions respectively establish the figure of a judicial expert doctor, and the figure of a forensic specialist. The second chapter focuses on the careers of those who embrace the medico-legal expertise field. It reveals how doctors’ positions on medico-legal expertise are reliant on the way they adjust the practising of this activity to their original medical education. Finally, the third chapter analyses the practices of experts and magistrates from the Public Prosecutor’s department, within the organisations where the medico-legal expert assessments are produced and used, from hospitals to courts of law. This ethnography of how medico-legal evidence is created underlines the tensions that come up within this activity stream, as doctors mix up different frameworks in the way they examine assaulted bodies.This mobile approach of the medico-legal apparatus allows the surfacing of two theoretical concerns. First, the logical hierarchy between the micro level of practises and the meso level of organisations leads to renew the approach for professional segments. Studying segmentation processes is a way of determining if forensic medicine is more driven towards being an activity that is piloted by the judicial administration supervision (which funds and consumes the expert assessments), or towards becoming an autonomous medical discipline with the same regulation mechanisms as a regular hospital specialty. This second concern leads to studying the socialization mechanism as well as the practises of experts in a dynamic way. Ultimately, this thesis proposes to analyse a practise that is stretched between different surroundings in concrete situations, while analysing specific social determining factors of the medico-legal assessment, by dynamically exploring three levels: the organisation of forensic medicine, the socialization of the experts, and the actual activity of the professionals that produce and seize medico-legal assessments

Texto completoThe ability to compose existing services to provide more complex functionality is one of the main benefits of SOA architecture. This services compositions process, especially Web services, is generally defined by a choreography or an orchestration of atomic services. These compositions are seen as a states-transitions systems expressing the communication protocol between the participating services. Services Workflows description languages, expressing these compositions, suffer from the lack of formal semantics and the presence of ambiguities in their constructors definitions in standards defining these languages. The associated tools do not offer the possibility to formally verify and validate the behaviour and the obtained services compositions properties. This thesis focuses on modelling and formal verification of the Web services composition described with the BPEL standard using the B event method. The proposed approach models the static and dynamic parts of BPEL and is based on refinement for structuring the BPEL process development. The theorem proving technique is used for setting properties. One-to-one link is guaranteed between the BPEL elements and their B Event corresponding. This correspondence provides assistance to developers to improve the quality of the BPEL process. This approach has been implemented in the BPEL2B tool
Khacef, Kahina. "Trade-off betweew security and scalability in blockchain systems". Electronic Thesis or Diss., Sorbonne université, 2022. http://www.theses.fr/2022SORUS516.
Texto completoThe development of Blockchain has enabled the emergence of high technology in the sensitive and active sectors by allowing the reliability of information via consensus, the immutability of records, and transaction transparency. This thesis presents the design, implementation, and evaluation of techniques to scale the blockchain. The first part of this thesis consists of building a decentralized, secure peer-to-peer messaging protocol using a PKI-based blockchain, which can be an email, a website, or some other form of message. Managing users’ identities by the Blockchain eliminates the single point of failure of traditional PKIs. By using smart contracts to validate, store and revoke the certificate on a public blockchain. Security and scalability are considered two significant challenges in blockchains’ rapid and smooth deployment in businesses, enterprises, and organizations. The ability to scale up a blockchain lies mainly in improving the underlying technology rather than deploying new hardware. The second contribution of the thesis proposes SecuSca, an approach that makes a trade-off between security and scalability when designing blockchain-based systems. It designs an efficient replication model, which creates dynamic sharding wherein blocks are stored in various nodes. To maintain the required level of security, the proposed approach shows that blockchain replication over the Peer_to_Peer network is minimized as the blockchain’s length evolves. Furthermore, a sharding protocol over the network is proposed to get access to the blockchain data based on historical transactions. The protocol reduces old blocks’ replication; these blocks can be discarded from specific nodes and stored by others. The nodes willing to store the coming blocks and their data are chosen randomly. The block header of each block is kept to achieve consensus. Next, we optimize the latest approach by choosing the entering nodes following the nodes’ capacities instead of randomly

Texto completoThe emergence of the logic of performance illustrates a major change in public or private human resources management strategies. The health care relation is exemplary of these evolutions. Historically, negotiations between the State and physicians exclusively focused on prices. However, since the beginning of the 90’s, public regulation is carried out through professional norms. The goal is to improve the quality of care and to control public spending (avoiding chronic diseases and encouraging the use of generic drugs). The introduction of pay-for-performance in France in 2011 is the ultimate stage in this metrological turning point defined by a numerically-based assessment of medical work. In an institutionalist viewpoint, our thesis seeks to question the relevance of this reform which aims at instituting performance.We show that this project is neither effective nor efficient. Leading to numerous perverse effects, it is implemented regardless of the patients’ interests and of the general practitioners. Contrary to what was proclaimed, this injunction for performance did not achieve the improvement of quality in medical care and the control of health expenditures. Yet, in the contemporary neoliberalism spirit, health is associated with a good as any other, surrounding which it is possible to generate competition among producers and consumers
Fiolet, Mathieu. "La fabrique des faits-divers : le travail des journalistes faits-diversiers dans la presse quotidienne locale". Thesis, Paris 10, 2016. http://www.theses.fr/2016PA100106.
Texto completoThe goal of this thesis is to understand how works a specific category of journalists from day to day: those who produce the “fait-divers” section in daily local newspapers. Even if articles of this section are very popular, newspapers readers, journalism students and even those journalist’s co-workers are ignorant of the functioning of this section. This thesis presents the “fait-divers” articles as products coming out of a factory and has the purpose to describe the machine that manufactures them. It takes an interest in its inner workings that are the different actors in the system, by listing them and by showing how these different “pieces” combine and work together. It focuses on the adjustments but also the dysfunctions of the machine. It takes an interest in the different ways of functioning, which aren’t the same from one newspaper to the other, and in the effects these ways of functioning can cause on those products coming out of a factory: the “fait-divers” articles. The investigation was conducted by participant observation. The author worked full-time during twenty months at different positions as a journalist in three different daily local newspapers located in three different districts. A series of interviews of about twenty journalists working in thirteen other French daily local newspapers was conducted, along with a systematic counting of the content of the “fait-divers” section of one of the studied newspaper, to complete this investigative work. The main theoretical contribution of this thesis involves an analytical description of a specific model of exchange relationships between journalists and state institutions such as police, judiciary, and emergency services. A model that is likely to apply to other work relationships in different professional backgrounds

Texto completoThe present work is a comparative analysis of discussion groups in German and French online press. By studying the use of discourse repetition, it aims at outlining the specific intertextuality of what may be considered as a discourse genre that is both cross-linguistic and cross-cultural. This study is based on conversation analysis and discourse analysis. These tools are used with the double purpose to describe the functioning of " discussion groups " as communication devices and to highlight the existence of a framework that requests the locutors to produce an opinion discourse and also an argumentative discourse. The main focus of attention is put on forms of discourse repetition and the functions that discourse repetition fulfils: the analysis of this discourse practice shows regularities. This may be partly explained by the functioning of the communication device and partly explained by the fact that discourse repetition is indeed a defining characteristic of this emerging genre

Diallo, El-hacen. "Study and Design of Blockchain-based Decentralized Road Traffic Data Management in VANET (Vehicular Ad hoc NETworks)". Electronic Thesis or Diss., université Paris-Saclay, 2022. http://www.theses.fr/2022UPASG017.
Texto completoThe prominence of autonomous vehicles has imposed the need for more secure road traffic data (i.e., events related to accidents, traffic state, attack report, etc.) management in VANET (Vehicular Ad hoc NETworks). Traditional centralized systems address this need by leveraging remote servers far from the vehicles. That is not an optimal solution as road traffic data must be distributed and securely cached close to cars to enhance performance and reduce bandwidth overhead. Blockchain technology offers a promising solution thanks to its decentralization property. But some questions remain unanswered: how to design blockchain-adapted traffic data validation, which is more complex than an economic transaction? What is the performance in real-world VANET scenarios?This thesis addresses those questions by designing blockchain-adapted traffic data management. The performance analysis and the validation of the proposed schemes are conducted through various simulations of real scenarios.We first adapt the PoW (Proof of Work) consensus mechanism to the VANET context whereby the RSUs (Road Side Units) maintain the decentralized database of road traffic data. After that, the proposed scheme is evaluated in the presence of malicious vehicles. The results show that the proposed approach enables a secure and decentralized database of road traffic data at the RSUs level.Next, motivated by our findings, we adopt PBFT (Practical Byzantine Fault Tolerance), a voting-based consensus mechanism, to reduce the blockchain latency. The traffic data validators are dynamically selected based on traffic event appearance location. Finally, we propose a novel blockchain replication scheme between RSUs. This scheme offers a trade-off between the blockchain latency and replication frequency. Simulation results show better performance when the validators (i.e., RSUs) are minimized.Finally, we propose a trust model to minimize the validators without compromising the decentralization and fairness of block-creation. This trust model leverages the geographical distance and the RSUs trust to dynamically form a group of validators for each block in the blockchain. We formalize and evaluate this trust model, considering various scenarios with malicious RSUs. Results show the efficiency of the proposed model to minimize the validators group while isolating malicious RSUs

Texto completoThis thesis focuses on the evolution of the relationship between Japanese daily press reporters and the newspaper companies for which they work. At the crossroad of the interactionist sociology of professions, sociology of journalism and economic sociology, this work is mainly built on fieldwork conducted within the newsroom of one national newspaper, the Asahi Shimbun, the second biggest newspaper in the world regarding circulation and readership. Journalism in Japan is structured around one central element: the company. Large companies train their employees, protect reporters from labor competition by integrating them in their internal market, and by controlling access to the main news sources. In turn, they expect from their reporters a strong commitment in work and the acceptance of the appropriation of their work by the company. All those items constitute the organizational logic of Japanese journalism. The first aim of the thesis is to describe the main features of this model, while showing how some elements related to an occupational logic subsist. A second aim is to analyze the impact of two movements. Specific to the newspaper industry, the first one is related to the evolution of the readership and the editorial policies established by newspaper companies confronted to this evolution. The second, which is more generally related to the world of work in Japan, refers to the transformation of the role played by the company in society. Observations conducted within the newsroom of this newspaper company during three years, qualitative interviews and a statistical analysis has allowed us to examine the careers and the division of labor, and to see what concrete evolutions are related to the weakening of the organizational logic

Texto completoIn its constitutive period, from 1895 until 1921, what was the position of the confederation generale du travail (CGT), as a "working class" organization - not always a united group, on the major issues of education, including the problems of professional training and apprenticeship, the question of education staffs, mainly teaching staffs? These are the questions that we endeavoured to reply to. Our research tools where congress reports and publications by the organization itself or placed under the responsibility of its main leaders. The research shows in particular that the cgt was opposed to the state monopoly over education and, consequently, its dissent with the republican morals taught in nondenominational schools. It underlines teachers' refusal of what was called "la laïque" (which designates the state primary school system in France) at the beginning of the century, then their acceptance, from 1905, whilst resolutely positioning themselves on the side of the revolutionary minority. It shows how, in 1914, CGT leaders used teacher activists who had died in the first months of the war, to strengthen their participation in the "union sacrée" (holy alliance). The research reveals that the CGT and its national structures had an ambiguous position concerning occupational training and apprenticeship, safeguarding more the interests of qualified workers - constitutive nucleus of the national center, than those of apprentices. . . Finally, the research shows how this period of the French trade union movement, often denigrated today, was creative, inventive of new policies in practically all areas of life, whether economic, social or cultural and hence in the field of education and training. It also shows how it has shaped the culture of the organization. In addition, this culture remains alive today in its activists, even those who feel they have moved away

Texto completoOver the past three decades, the industrial and editorial strategies of French press groups pushed the journalistic labour markets to adapt to new requirements. Faced with these changes, the traditional positions of the actors involved in the journalistic field were deeply challenged leading to a reconfiguration in terms of standards and socio-discursive practices, but also in terms of the distribution of roles and powers. Our research focuses on the case of the French “pigistes” journalists who are located in a "grey area" of the labour market and thereby become privileged "analyzers" of the ongoing changes in the French press industry. The precariousness assigned to them is examined as a relational notion, which allows us to approach very closely the "breakdown-restructuring" movement of the modern French journalistic field. The study of the uses of this notion in the discourses of the main actors in this field brings light on the social logics at work. It underlines what is at stake in the stigmatization of “pigistes” journalists in "precarious" professionals on the one hand and which strategies this stigma help to satisfy on the other hand. It appears that this representation implies a differentiation between two types of journalists (the precarious ones and the others), which singularly makes sense in a socio-economic restructuring of cultural industries. Revealing a tension between legitimacy and modernization of a changing press, the precariousness assigned to the “pigistes” journalists supports the adaptation strategies of the actors involved in the field. Above all, this stigmatization serves firstly this stigmatized journalists who by conducting a “reversal of the stigma” seize the opportunity to bring forth a “para-journalistic” identity based on a culture they would own: the “pigisme.”

Texto completoThis thesis deals with the process of valorization of national daily newspapers on the two-sided market of the press (readers and advertisers) and considers the role of the edition activity in the creation of value. The analysis of the activity of “press workers” (writers, editors, managers, commercials in advertising agencies) aims at describing the production of an hybrid good, both informational and advertising, of which final characteristics result from operations of qualification and valuation of contents, and from editorial and technical operations that transform editorial projects into edited products. The observation of editorial work and edition systems uses in daily press newsrooms shows a process of rationalization of the conception and production of newspapers. Editors want to master this process in order to reinforce their control of edition and valorization of newspapers, but industrial rationalization does not guarantee firms profitability in a changing market of informational goods. To face uncertainty of newspapers valorization, editors take action on the editorial position of papers and on the work of edition done by editorial staff, and they engage the development of cross-media newsrooms. The activity of contents edition is at the heart of the value chain of newspaper, but the evolution of cultural practices and the transforming media landscape put in question business models of newspapers and challenge work practices as well as representations of occupations in newsrooms
Wilson, Têtê Norbert. "Impact of physical activity on return to work after cancer diagnosis : an evidence-based approach". Electronic Thesis or Diss., Angers, 2023. http://www.theses.fr/2023ANGE0063.
Texto completoPhysical activity (PA) is one of the leading supportive care programs recommended by several guidelines to improve most of cancer side effects experienced by cancer survivors, because of the strong evidence of its effectiveness on these health outcomes. However the evidence on the effectiveness of PA on return to work (RTW) in cancer survivors remains limited and unknown. In addition, it is unknown whether the recommendations from existing PA guidelines are applicable to RTW after cancer diagnosis. Therefore, the objective of this thesis was to evaluate the effects of PA programs or interventions on RTW in cancer survivors and provide evidence for the effectiveness of PA on RTW after a cancer diagnosis. To address the research question, we used evidence-based methodology (systematic review, meta-analysis, and rapid review). This thesis showed that PA programs are feasible and safe for cancer patients. We found that PA interventions have significant positive effects on RTW in cancer survivors. The dose of PA comprised between 7.6 and 15 METs.h/week, consisting of 100-120 minutes per week of moderate to vigorous intensity aerobic and resistance exercise, seem to be effective in improving RTW after cancer. In conclusion, this thesis provides moderate evidence on the effectiveness of PA interventions on RTW in cancer survivors. It also allowed us to estimate the dose of physical activity needed to improve RTW in cancer patients. Based on these findings, we proposed a guidance with practical protocols for prescribing and implementing PA programs to support RTW in breast cancer survivors

Texto completoIn 1839, cesar daly (1811-1894) issued the revue de l'architecture et des travaux publics which was published up to 1890. This periodical, quite modern as regards its presentation (page-setting, engraving treatment) and its subject (it is meant not only for engineers and architects but also for painters, ornemanists, barristers, historians and archeologists) will soon give rise to many imitations (moniteur des architectes, encyclopedie d'architecture) and will be widely diffused in france and abroad. Being at the melting-point of a complex heritage where the ideals of the "siecle des lumieres", the "modernism" of the romantic inspiration, the enthusiasm of fourrier's followers and the practical efficiency of saint-simonien's school converge, the r. G. A. Intends to make engineers conscious of the rules of art, to give architects a technical training, to work to the progress of humanity. Its most active contibutors counted among the neo-grecs architects and the young representatives of the most progressive and critical movement the ecole des beaux-arts had ever produced. This team was to be renewed many times but in spite of some tensions (conflicts with didron, davioud, viollet-le-duc), its cohesion remained. In this periodical the technical, practical and historical language aroused the production of a theorical thought. Daly's aesthetic is based on the knowledge of the "passe tout entier", turns towards the ideas of development and progress and to the apology for ellipsis, a form which should encourage the architecture of future. If history is called to serve modern architecture, contemporary production is conceived as a consideration on programmes (schools, hospitals, churches, theatres, stations workers'housing, markets etc. ). In its plates (very well-finished and engraved on steel) and articles, the r. G. A. Devotes an important place to provincial architecture

Texto completoThe institution of human relations in the company has created new management methods, and in which the mobile communication was fundamental. In this way, the human factor could be reconsidered in the labor’s organization and employees’ participation in the operation of the company was awake. We chose to analyze the representation of human relationships, through the internal newspaper within the group Elf, to reveal all the practical and technical implementations to allow employees to be happy within the company. Apart from its role of information, with the aim to sensitize employees to the objectives and challenges of the company, the internal newspaper is also a space for expression in which managers and employees identify themselves with an approach collective. It reproduces the human relationships that are born, through the organization and the professional challenges of the business. Because of its content, the newspaper group Elf seems to accompany the company in its role in society through human figures, it carries within it. Such like, there remains an exchange link which supports a triangular relation between the firm, its employees and its external environment
Grossi, Valentina. "L'image négociée. Une sociologie des professions du photojournalisme à l'ère numérique". Thesis, Paris Sciences et Lettres (ComUE), 2018. http://www.theses.fr/2018PSLEH136.
Texto completoMany observers argue that the professions revolving around photojournalism are facing a deep crisis in recent decades due to increased competition with image banks and amateurs. However, several organizations continue to handle the production of photojournalistic images in a specialized manner, championing the importance of maintaining what they refer to as a “professional” attitude towards these objects. How can some actors successfully claim the “license” to produce these artifacts and the possibility of autonomously defining their own “mandate”, while their monopoly over this activity is no longer taken for granted? A two-pronged inquiry, both historical and ethnographic, will provide an answer to this question. The ethnographic part of this research was carried out on three French editorial boards: the photo service of an international news agency, the editorial staff of the print edition of a national newspaper, and the web editorial team of a news magazine. This investigation showed that the strong division of labor in media companies is not at odds with the exercise of professional autonomy, understood as the ability, for actors, to implement complex assessments while reflecting on the very aims of their activity. The virtuosity of photojournalism professionals consists in bringing together heterogeneous constraints, which are not reducible to the simple logic of profit. These constraints are reinforced and updated through interactions between actors who compose the different professional segments and through the contacts they maintain with external groups (i.e. the sources and the public). Autonomy is therefore the result of a sui generis work organization that allows professionals to develop a specific morality in connection with that of neighboring groups as well as the “intelligence” of their activity. However, tendencies towards “deprofessionalization” are also noticeable: the actors’ autonomy is undermined when production systems tend to individualize work and, at the same time, to abolish complex judgment. This thesis thus aims to contribute to current discussions on the impact of digital technologies and new forms of work organization on professional autonomy

Texto completoThis thesis studies the reception and the reintegration in society of Vietnam war veterans as they are represented in two American dailies, The New York Times and The Washington Post. To this comparison between the two newspapers are added the analyses of two weeklies, The Nation and Newsweek, and a bimonthly, National Review, which provide a complete range of the various point of views on the subject. Two periods stand out: from 1966 to 1970, the reintegration of the former soldiers seemed to be easy, according to the newspapers. From 1971 to 1978, the coverage by the media first intensified owing to the difficulties of reintegration that the Vietvets faced and dared to voice loudly for the first time; the press then appeared to progressively lose interest in them. The evolution, in the newpapers, of the representation of the veterans and of their reintegration mirrored the evolution of American society and economy. If both dailies a priori addressed the same kind of readers, the reality that they chose to present and distort through their ideological bias often differed. The thesis also tries to show how their representations may have helped or hindered the reintegration of Vietvets in society

Texto completoMay Day, an eminently political holiday of the socialist workers' movement, became with the celebration of May Day 1933 an official holiday of the National Socialist regime, an embodiment of its social community project, the "Volksgemeinschaft". But did these political rituals really contribute to the creation of a social order or were they merely a deceptive reflection of the regime's communication? In fact, May Day - a public holiday and festive day since 1933/34 - was a device of power(s), of inclusion and exclusion, which aimed at this social fabrication through political and official celebrations but also through the development of leisure activities within enterprises. It contributed to the emergence of a new, unequal and racist social order through classical mechanisms of inclusion and exclusion or even social ascension for the benefit of the >Volksgenossen< and >Volksgenossinnen< thus defined, not only through coercion but also in a constant process of negotiation. The festive and media arrangements had disappointing results, as the organisers (Joseph Goebbels) did not succeed in implanting the partisan mobilisation model inherited from the NSDAP in the heart of German society. In addition to this model, which was particularly highlighted in the media, new social rights were created: the right to holidays - guaranteed by this public holiday, among others - the right to leisure and tourism, as well as access to the consumption of "community services", including the festive evenings organised everywhere for the benefit of Robert Ley's DAF. At the same time, Jewish Germans were excluded from these "community" rights with difficulty. This exclusion clearly defined the "People's Community", while its meaning remained open to debate between "Community of action" through participation, "Community of effort" through processes of distinction, and "Community of leisure"

Texto completoThe research aims to show how social representations of young people in integration, local missions and integration have evolved over time and over a territory, the pays d'Auge in Normandy. The research is based on the theoretical plan of work on social representations (Moscovici, Jodelet, Abric, etc.). The hypothesis was to think that social representations varied on the one hand, according to the level of social and economic development of the territories and on the other hand, according to the periods and the course of time. To test this hypothesis, we used two methods of data collection. To compare the representations on employment areas, we interviewed 30 people involved in the professional integration activities of young people (integration professionals, elected officials involved in integration and journalists who wrote on the subject) through semi-structured interviews to collect their perceptions about integration and changes over a period of 35 years (1982/2017). The data was processed by thematic content analysis. A second modality consisted of collecting and analyzing 211 local newspaper clippings over the 1982-2017 period in order to identify any changes in the perception of integration and local missions, structures specialized in welcoming young people. The data was processed by the Alceste software. The results highlight an evolution of perceptions of insertion in the Pays d'Auge over time as well as differences between the two areas of employment (Honfleur and Lisieux). The area of Honfleur, more dynamic testifies to more positive representations of insertion while the Lisieux area, more difficult social and economic is associated with negative perceptions. These results confirm the observations of Moscovici and Jodelet according to whom, the variety of exchanges and interactions can initiate and change the representations within a working community (here actors of insertion). It also helps to observe how a social object such as insertion manifests itself and changes over time. This type of research should be replicated in other territories in order to identify more precisely the singularity of the links between exchanges between actors and the economic and social development of a territory, as well as their manifestation by social representations

Texto completoIn the second half of the 18th century, the rise of theatrical entertainment and the changes in public space transformed the profession of acting. This thesis aims at identifying the modalities and issues of these changes in the capital, based on the trajectories and work experiences of actors and actresses. At the Comédie-Française, the Comédie-Italienne, as well as in the boulevard theatres, the professional world of actors and actresses is structured at different levels, according to institutional, commercial and political developments. Since the specificity of the profession is to perform on stage in front of spectators, this investigation analyses the importance of public recognition through the prism of work practices. Development of press and new forms of visibility in the city shape careers. They also contribute to redefining the hierarchies and the profession identity, which acquires a new place in society over the studied period. This thesis is thus a contribution to the social history of artistic work, shedding light on a certain number of cultural mutations during the last decades of the Ancien Regime and the Revolution
