Gardy, Danièle. "Bases de données, allocations aléatoires : quelques analyses de performances." Paris 11, 1989. http://www.theses.fr/1989PA112221.
Повний текст джерелаThis thesis is devoted to the analysis of some parameters of interest for estimating the performance of computer systems, most notably database systems. The unifying features are the description of the phenomena to be studied in terms of random allocations and the systematic use of methods from the average-case analysis of algorithms. We associate a generating function with each parameter of interest, which we use to derive an asymptotic expression of this parameter. The main problem studied in this work is the estimation of the sizes of derived relations in a relational database framework. We show that this is closely related to the so-called "occupancy problem" in urn models, a classical tool of discrete probability theory. We characterize the conditional distribution of the size of a relation derived from relations whose sizes are known, and give conditions which ensure the a. Symptotic normality of the limiting distribution. We next study the implementation of "logical" relations by multi-attribute or doubly chained trees, for which we give results on the complexity of a random orthogonal range query. Finally, we study some "dynamic" random allocation phenomena, such as the birthday problem, which models the occurrence of collisions in hashing, and a model of the Least Recently Used cache memory algorithm

Повний текст джерелаOne of the oldest and most prominent definitions attributed to Corporate Social Responsibility (CSR) is that given by Howard Bowen who refers to as the father of CSR for his “landmark” 1953 book, Social Responsibilities of the Businessman “The obligations of entrepreneurs to pursue those policies, to make those decisions, or to pursue desired lines of action in terms of the aims and values of our society” (Bowen, 1953a).Later, (Carroll, 1979a) focused rather on firm obligations to certain responsibilities to society that extended beyond the economic and legal domains to include employee and community welfare, the political and educational needs of society and service to improve the quality of human life and defined CSR as: “Social responsibility of business encompasses the economic, legal, ethical, and discretionary expectations that society has of organizations at a given point in time”. Nowadays, CSR is recognized at the global, national, regional, and even local level, mostly as a “voluntary contribution to sustainable development” (Jurkowska-Gomulka et al., 2021). The voluntary concept of CSR views CSR as firms’ commitment to sustainability that is beyond the legal requirements.However, CSR is become crucial part of a company’s strategy plan and a real concern of many industrial companies (Widad et al., 2021). As a result, several organizations have implemented different initiatives to encourage companies to adopt CSR approaches, such as Economic Cooperation Development, United Nations Global Compact, International Labour Organisation, and Global Reporting Initiative (GRI) (Shehabi et al., 2016). All these initiatives have contributed to developing a unified CSR framework known as ISO 26000 standard published by the International Standard Organization (ISO) in 2010 (Popa & Dabija, 2019). ISO 26000 defines CSR as: responsibility of an organization for the impacts of its decisions and activities on society and the environment, through transparent and ethical behavior by taking into account the stakeholder’s expectations (ISO, 2010). Socially responsible behavior of companies is expected nowadays by a wide scope of entities: mainly consumers, but also trading partners, contractors, and public authorities (Haseeb et al., 2019). Under these circumstances, CSR is no longer voluntary, but is becoming a strong moral or even legal duty (some groups of companies are legally obliged to report their non-financial activities in publicly available documents). Companies have become increasingly aware of the dangers that their activities can cause to the planet and to society in the future. Mindful company (MC) represents a company mindset of caring for society, community and environment which manifests behaviorally in the tempering on activities of which is both defeating and environmentally unsustainable

Повний текст джерелаThe main aim of this doctoral dissertation was a better understanding of the emotional process (the emotional determinants to the emotional consequences on sporting performance) that takes place for regional and national table tennis players during their matches in a competitive context. For our study we filmed the participants in competitive situations and noted the participants’ comments during retrospective interviews. These comments referred to the nature of emotions experienced by table tennis players, the cognitive appraisal of the emotional situation, the strategies of emotional regulation used, and the directional interpretation of their emotions. The comments of the participants were analysed by quantitative and qualitative means. The quantitative analysis enabled characterization of the number, nature, duration, direction and co-occurrence of emotions experienced by participants during a competition. Moreover, results suggested that non-punctual emotions, compared to punctual emotions, have a more important impact on the performance of table tennis players. Qualitative analysis (i. E. , grounded theory) showed: (1) the cognitive contents of the appraisal process of per-competitive specific emotions, (2) the characteristics (nature, perceived effectiveness) of the emotional regulation process during competition, (3) the contents of the directional interpretation of per-competitive specific emotions, and (4) the emotional process of each of the per-competitive specific emotions experienced by participants (identification of the concepts and their relationships)

Повний текст джерелаThis thesis examines the types of relational strategies that firms can adopt with their competitors in a network industry : the mobile phone industry. It also purposes to highlight the determinants of these strategic choices and their implication. Finally, it aims to make a comparison of the performances of firms, according to their relational strategies choises. To address these concerns, we used, on one hand the method of structured content analysis so as to identify the strategic movements of the mobile phone operators of different countries and geographical areas ; on the other hand, we used two methods (exploratory and confirmatory) analysis for data processing. Through this thesis, we highlight three key findings : The first result shows that competitive aggressiveness, cooperativeness and coopetition are the viable relational strategies in the mobile phone industry. The second major result shows that the sectorial variables such as industrial concentration, sectorial maturity ; or more or less international presence appear to be factors determining the strategic behavior (aggressive, cooperative and coopetitive) of the mobile operators ; as well that more aggressiveness and more cooperativeness lead to better performance. Finally, it is shown in this study that the performance of the firm depends on the strategy (aggressive, cooperative, or coopetitive) adopted by the mobile operator, but also on its geographical location

Повний текст джерелаIn a supply chain, the value creation potential can only be achieved through effective management of inter-organizational relationships (Madhok and Tallman, 1998). Xu and Beammon (2006) underline the need for a set of resources and tools to manage interdependencies and take consistent decisions while emphasizing the importance of coordination mechanisms. Thus, the objective of this thesis is to figure out elements that make up the inter-organizational coordination in the supply chain. Moreover, we analyze inter-organizational coordination between supply chain partners and the role of contractual and relational mechanisms for managing their interests and resolve conflicts. More specifically, through this Dissertation we seek to answer the following question: What is the impact of coordination mechanisms and contractual relationship on inter-organizational coordination of the supply chain? To better understand this phenomenon, a qualitative study was conducted with fifteen professionals in supply chain management field. A thematic content analysis helped define more accurately the various components of inter-organizational coordination. The collected materials were confronted with the analysis of the literature and then tested on a sample of 216 respondents in the field of supply chain management. Quantitative data collected was analyzed using a principal component analysis in order to purify our scales. We then used the PLS -PM of structural equation models (Partial Least Squares Regression) to estimate the convergent and discriminant validity of the measurement scales validity. This method allowed us to validate our research hypotheses concerning the model of inter-organizational coordination of the supply chain. The results of this research highlight the link between the mechanisms of coordination and contractual relationship and their impact on collaboration, their roles in mastering the difficulties of coordination and their weight on the evaluation of the effectiveness of the contract. We also studied an impact on the type of partner (strategic, non-strategic) on inter-organizational coordination of the supply chain

Повний текст джерелаResource and competence theory is applied to multiple fields and countries. It seems pertinent to infer a possible use to the management of supply chains to better understand the operation. This is the goal of this thesis by questioning the nature of resources and logistic expertise in the hands of logistics service providers (LSP), and how they are mobilized as part of a maneuver integration of the supply chain between industrial and PSL to improve logistics performance perceived by the industry. The conceptual framework developed in the thesis is based therefore on both the resource and competence theory and in-depth analysis of the supply chain integration process. By relying on an extensive literature review, we build a model based on five research proposals relating to the relationship between supply chain integration and perceived logistics performance, which also involves the innovation capacity that can demonstrate LSP. A questionnaire survey was conducted in Vietnam with the participation of 139 food actors. The main results of the research can be summarized in two points. On the one hand, the integration of resources and logistics expertise between industrial and LSP impacts heavily on logistics performance perceived by the industrial. On the other hand, the innovation capacity constitutes for the LSP an important resource, which can have a significant impact on logistics performance perceived by the industrial

Повний текст джерелаNowadays, the importance of the maintenance function has increased, due to the requirements on the maintain in operational conditions phase (MCO) of the system-of-interest (SI). As well as for the relevant role of maintenance in improving availability, performance efficiency, total plant availability, etc. To control performances, maintenance managers should be able to make some choices about the maintenance strategies and the resources that can fulfil the requirements. Within this context, we propose a methodology to formalize a model allowing to perform simulation to assess maintenance strategies. The scientific contribution of our work is that this approach unify by using a probabilistic relational model (PRM), different kind of knowledge needed to assess maintenance strategies. Knowledge is presented as generic and modular patterns based on PRM. These patterns integrate relevant decisional variables of the system of interest and of its maintenance system. This approach eases the modeling phase for a specific application. This methodology is one of the results of the project ANR SKOOB. This approach was tested on an industrial case for the maintenance of a harvest production process

Повний текст джерелаBoth among researchers and practitioners, organizational socialization seems to be a topic of interest nowadays (Fang, Duffy, & Shaw, 2011). Along this line, the present thesis seeks to deepen our understanding of organizational socialization in order to provide a more complete and documented picture of it, but also to develop useful practices for organizations and their employees. Specifically, the relational aspects inherent to the experience of newcomers, largely ignored so far in the literature (Ashforth, Sluss, & Harrison, 2007), are examined using data collected at three points in time among a sample of 224 newcomers. Using social exchange theory (Blau, 1964) as a background and the concept of affective trust (McAllister, 1995), the first of the two articles that comprise the thesis shows that, compared with conventional approaches (i.e., expressing a cognitive view of organizational socialization), a relational approach to organizational socialization can better reflect the psychological bond that is established between newcomers and organizations, while conventional approaches are more explanatory of employee performance. The two approaches thus seem complementary to explain newcomer adjustment. The second article draws from the evidence reported in the first article and seeks to further deepen the relational aspects inherent to the experience of newcomers, as well as their influence on adjustment. To this end, conservation of resources theory (Hobfoll, 1989) is considered and affective commitment (Meyer & Herscovitch, 2001) is put forward as the focal concept. Results suggest that affective commitment to the supervisor compensates for a decline in affective commitment to the organization as resulting from a breach to individuals’ relationship with the organization. Relationships thus seem, under certain circumstances, to have an impact that goes beyond their direct protagonists. This thesis therefore demonstrates that the relational aspects inherent to the experience of newcomers have a distinct, prevailing and complex influence on their adjustment. In doing so, it is part of a research stream that tries to put forward and better understand the relational dynamics within organizations (Ragins & Dutton, 2007). Theoretical and practical implications will be discussed.
Guilmaine, Anne-Marie. "L’empreinte d’une expérience performative en littérature : le cas de Sophie Calle et de Miranda July." Thèse, 2015. http://hdl.handle.net/1866/16117.
Повний текст джерелаThis master’s thesis proposes to establish a dialogue between the practices of two contemporary writers and artists, Sophie Calle and Miranda July. The four studied pieces of work – Calle’s Douleur exquise (2003), Aveugles (2011) and Rachel, Monique (2012) and July’s Il vous choisit (2013) – are based on concrete experiences occurring beforehand, prior to the act of writing itself. Those experiences mobilize the body of the writers engaging them in a real action and often in interactions with other people. This form of action art becomes the foundations of their writing and could be linked to the theories of pragmatic philosopher John Dewey and artist Allan Kaprow – one of the first to develop a reflexion on performance art. The intermedial writing that Calle and July practice as a game of relations between different medias in the same work allows both artists to revive the performative value of the experience. It impulses the writing and initiates a reading experience which itself becomes performative. Exemplary of a relational aesthetic, polyphonic in the voices that are expressed, the studied body of work reveals glimpses of community to feel and experiment. It is a literature that is interdisciplinary and intersubjective but primarily performative in its constant questioning of art’s capacity to transform life.
