Le présent manuscrit développe une problématique liée à l’implication des capacités de gestion de buts et d’engagement des fonctions exécutives dans le raisonnement par analogie et son développement. Les trois premières expériences étudient cette problématique dans deux tâches de raisonnement par analogie différentes à travers l’étude des stratégies visuelles employées par des adultes et des enfants de 6-7 ans. Les résultats montrent des différences de stratégies visuelles entre les tâches, liées aux buts différents de celles-ci, ainsi que, entre enfants et adultes, des différences de patterns visuels liés à l’inhibition de l'information non pertinente pour la résolution des problèmes. Les deux expériences suivantes étudient les stratégies visuelles, toujours en lien avec le fonctionnement exécutif et le maintien du but, dans une tâche A:B::C:? dont la difficulté est manipulée afin de mettre en évidence des différences d’engagement de processus de contrôle et d’évaluation. Les résultats montrent un effet de la difficulté des essais, ainsi que du type de distracteur, dans les stratégies visuelles. Enfin les trois dernières expériences étudient l’implication de la flexibilité cognitive, une des fonctions exécutives, dans le raisonnement par analogie, chez l’enfant (5-6 ans), limité dans sa flexibilité. Les résultats montrent que l’ancrage dans un type de représentation, pertinent ou non pour la solution du problème, est lié à leur capacité à résoudre le problème, et suggèrent une difficulté à changer de représentation au cours de la résolution. Ces résultats sont finalement discutés en rapport aux modèles de raisonnement par analogie et de développement de cette capacité. / This manuscript develops an issue related to the involvement of goal management capabilities and executive functions in this type of reasoning and its development. The first three experiments examine this issue in two tasks of analogical reasoning, the scene analogy task and the A:B::C:? task, through the study of visual strategies used by adults, and children aged 6-to-7. The results show differences in visual patterns related to goals, and to the inhibition of irrelevant information for the solution of the problems, between the different tasks, and between children and adults. The following two experiments study the visual strategies, always in relation to executive functioning and goal management, in an A:B::C:? task whose difficulty is manipulated to highlight the difference in involvement of monitoring and evaluation processes. The results do show an effect of the difficulty of the test and the type of distractor in the visual strategies employed. Finally, the last three experiments investigate the involvement of cognitive flexibility, one of the executive functions, in the analogical reasoning of preschool children (5-6-year-olds), limited in their flexibility. The results show that their early anchoring in a type of representation, relevant or not to the solution of the problem, is related to their ability to solve the problem later, and thus suggest a difficulty in shifting their representation during the resolution of the problems. These results are finally discussed in relation to models of analogical reasoning and of the development of this ability, especially those integrating goal management and executive functions.

Le secteur associatif a pris une place considérable dans nos sociétés contemporaines. C’est un objet d’étude de la sociologie. L’accroissement de la sphère collective, sociale et publique fait aussi de l’association, une organisation utile pour la Société Civile et la firme. Sous différentes dénominations, elle s’est imposée pour réguler des professions, des métiers, des activités commerciales, des produits, des marchés voire des firmes. Dans le secteur des Cafés Hôtels et Restaurants, le potentiel stratégique d’associations de support à la firme telles que la Société des Meilleurs Ouvriers de France, les coopératives publicitaires des réseaux de franchise, les Disciples d’Escoffier, le Comité Français de Modernisation de l’Hôtellerie ou encore la Fédération des Franchisés ACCOR est analysé. Quatre groupes de théories (théories sociologiques, théories de la nature de l’association, théories des Institutions et théories des Organisations) permettent de mettre en évidence sa raison d’être et son utilité pour la firme. A des spécificités propres à ce mode d’organisation correspond une approche managériale autonome qui emprunte au management des affaires publiques et privées. / The voluntary sector has taken an important place in our contemporary societies. It is a topic of study for sociology. The increase of the collective, social and public sphere also makes of the association, a useful organization for the Civil Society and the Firm.Under various names, she was imperative to regulate occupations, jobs, businesses, commercial activities, products, markets and even firms. In the sector of Coffees, Hotels and Restaurants, the strategic potential of associations of support to the firm such as the Company of France’s Best Workers, the advertising cooperatives of the franchise networks, the Escoffier’s Followers, the Hospitality Modernization French Committee or the ACCOR Franchisees Federation is analyzed. Four groups of theories (sociological theories, theories of the nature of the association, Institutions theories and Organizations theories) allows to highlight its purpose and its utility to the firm. At the appropriate specificities of this type of organization corresponds an independent management approach which borrows from the management of the public and private affairs.

L'objet de notre étude est la requête adressée à un moteur de recherche Web par un usager dans le cadre d'une recherche d'information. Nous souhaitons mieux comprendre l'étape de la recherche d'information située entre le besoin d'information et la formulation / reformulation de la requête. Notre thèse est articulée autour de deux hypothèses de recherche. D'abord, nous avons émis l'hypothèse qu'une requête adressée à un moteur de recherche Web peut receler de l'implicite. Ensuite, nous avons considéré que ce contenu implicite peut être utilisé par les usagers dans des tactiques de formulation / reformulation de la requête. Nous avons notamment analysé le discours de 61 étudiants que nous avons interrogés sur leur intention de recherche. Ce discours était principalement constitué d'un niveau sémantique (qui décrit le thème de la recherche) et d'un niveau pragmatique (composé d'un but seul ou d'un but ou plusieurs sous-but(s)). Les termes représentant le niveau sémantique pouvaient être complètement ou partiellement formulés dans la requête, mais ceux représentant le niveau pragmatique n'étaient généralement pas formulés. Cette situation de communication s'apparente à une négociation entre le moteur de recherche et l'usager. Le moteur de recherche tente de disposer d'éléments sur le besoin d'information de l'usager et ce dernier tente d'obtenir à partir d'un contenu explicitement formulé dans sa requête, un ensemble d'information afin de progresser sur la résolution de son problème / The object of our study is the query, sent to a Web search engine, by an Internet user. We aim to reach a better understanding of the phase of information seeking located between the information need and the query formulation. Our thesis is based on two core hypotheses, all related to the query. Firstly, we considered that the query expressed partially the user’s information need and therefore contain an implicit part. Secondly, we also considered that the implicit part can be used by the users in their query formulation tactics. We notably analyzed 61 students’ speech about their search intent. The speech was based mainly on a semantic level (the terms representing the topic of the research) and a pragmatic level (composed of an only purpose or purpose and of many under purposes). The terms representing the semantic level could be rather completely or partially formulated in the query but those representing the pragmatic level weren’t formulated. This situation of communication is similar to a negotiation between the Web search engine and the user. The search engine Web tries to have elements on user’s information need and the user tries to obtain, from a contents explicitly formulated in his query, a set of information in order to progress on his resolution of its problem

Further, the work describes the proposal of platforms for controling the BLDC motor. Low leve software is programed for these chosen platforms. The logic of controling and user interface is created. The logic of controling is created and tested in Simulink. Further more whole programmed code is connected with the low level layer. The whole solution of my diploma thesis is tested.

Nowadays there is research into molten salt reactors. The use of chlorine-based salts, which would be more available than known fluoride salts, is envisaged. The subject of research is not only the chemical and physical properties of chloride salts, but also their behavior in the neutron field and the influence of neutron balance inside the reactor. Many properties can also be determined using calculations that draw information from scientific nuclear libraries (endf). The purpose of this work is to compare important nuclear libraries with each other, and also to compare the reaction rates calculated from the library data with the reaction rates obtained by self-measurement. The preview will include a description of the necessary activities associated with the preparation of measurements, instructions for compiling the computer program NJOY and the process of the measurement itself. At the end of the work will be summarized the results and statements of which nuclear library is the closest in its values to the results of experiments.

The master's thesis is focused on optimal selection of transportation solution provider as a key activity of inbound logistics department of manufacturing company ABC s.r.o. The summary of general activities and objectives of inbound logistics are followed by the analysis of last selection procedure. Then there is mentioned suggestion of new selection procedure using the methods of Multiple Criteria Decision Making which is based on the knowledge from specialized logistical literature. This work assume that using the methods of Multiple Criteria Decision Making will result in more effective selection procedure in company ABC s.r.o.

Improved production and reduced consumption of beef is often highlighted as key aspects for tackling sustainability issues of the food system because the environmental impact of beef is ~100 times higher than plant-based foods. Both scientist and civil society organisations argue that eating “less but better” beef is important for sustainability. Better quality can encompass better eating quality as well as improved sustainability, but despite the two being very important for overall quality, very little research on interactions between them exists. No tools, applicable in Sweden, allowing for joint assessment have been developed. This study investigates the synergies and trade-offs between eating quality and environmental sustainability by using Swedish beef production as a case study. It reviews peer reviewed literature on factors that contribute to eating quality (flavour, tenderness and juiciness), and four factors that contribute to environmental sustainability (climate, biodiversity, feed/food competition and animal welfare). Based on the findings, an indicator-based sustainability assessment framework and a meat quality grading scheme differentiating Premium and Standard eating quality is developed, aimed to be practical tools for Swedish beef assessments. The study provides a systems-based understanding of synergies and trade-offs that may occur when “less but better” is presented as a strategy for tackling the environmental impact of beef. Results show that there are synergies between eating quality and biodiversity, animal welfare and with the right choices of feed, feed/food competition but with consequent trade-offs with climate impact. The discussion addresses the potential of enhanced eating quality to increase the profitability of Swedish beef production without consequent substantial negative impact on sustainability. The suggested methods have the potential to facilitate a shift from quantity- to quality-based consumption, but further empirical studies are required.
