Full textOur research tries to carry a critical glance on a rather abundant literature as regards loyalty. It proposes as objective to widen this prospect thanks to integration of concepts and the bringing together of theories and approaches which are generally treated separately. This thesis seeks to show that in order to consider loyalty in the context of a consumption of experiential nature, it is necessary to change the framework of analysis. The objective is to go beyond the vision reducing consumption to an instantaneous act towards a more global solution presenting consumption as an experiment lived by the consumer before, during and after the physical act of consumption. We try to study up to what point the perception of quality (particularly the service quality) allows to explain the force of the relation binding a consumer to his service supplier. Our approach of perceived quality tries to lay the stress on the complementarity of the cognitivist and experiential paradigms. It is a question of studying and checking the validity of a complex network of theoretical relations thus breaking with the behavioural approaches largely developed in marketing. Then, we try, through an empirical study, to test the validity of the relations highlighted in the literature within the framework of an experiment of consumption of a hotel service

In first, the objective is to clarify the concept in particular in relation to neighbouring concepts and to analyse his place in consumer behaviour. Then, this research attempts to modelize brand image perception by consumer in automotive domain. At last, a typology of consumers is realised according to automotive brand image perception

Full textThe present study aims at showing that situational factors can contribute to a better understanding of the perceived assortment variety. While perceived variety is one of the most important choice criteria of a superstore, it has not received much emphasis. Although most of the few studies in that field use the variety-seeking model and deal with the strict sense of the word “variety”, our research applies the heuristic-systematic model (Chaiken, 1980) to show that evaluation process may alternatively depend on : variety, size or both. A study of the perception process in wine department of a superstore emphasizes the role of context and situational factors on perception, regardless of assortment structure

Full textThe purpose of this study consists in apprehending conditions of appearance and the function of a coherent and accurate spatial representation of the city. This research leans on the experimental method applied on place, and focuses on a molar unit of analysis, namely the man/environment system. The two entities of this system being culturally marked, we have operate experimental variation on cultural distance inside the system by comparing southern European students and sub-Saharian Africa students, preserving Paris, a city imbues of European culture, as the unique place of study. It's therefore in terms of familiarity, and particularly in terms of socio-spatial familiarity, that the results are interpreted. It proves that urban area has no meaning in itself. So the storage of socially elaborated meanings appears important for an accurate cognitive map of the city. Thus, differences observed, up to now, in cross-cultural comparaison of cognitive map can also come from the legibility of socio-spatial characteristics of the city. Besides, urban pratices favor storage and diversity of meanings. Nevertheless, their impact on accuracy of cognitive map reminds limited. Then spatial information has an instrumental function permitting to resolve daily problems of spatial order. But it also have a psychological function enable to increase the feeling of coherence by adjusting represented space with real space. Otherwise, the spatial information is not only a tool for activities, its contributes to the elaboration of a life-place. However, this psychological function is possible only if the spatial information fills previously an instrumental function, as Kaplan explains in his model of person/environment compatibility

Full textThe aim of my PhD was to study the perception of two musical dimensions : pitch (i. E. , harmonic relation between tones) and time (i. E. , rhythm and meter). Numerous research has been interested in the perception of pitch and time separately but only few have focused on their joint processing. The independence or interaction of pitch and time processing as well as their underlying neuronal networks involved have been studied in my PhD. In a first part, using a behavioral approach of cognitive psychology in healthy listeners, three experiments studied influence of the level of processing and the material used on the processing of pitch and time dimensions. The findings suggest that the independent or interactive processing of pitch and time depends on the level of processing: in the first levels, the two dimensions seem to be processed independently but interact at later levels of processing in integration. In a second part, using a neuropsychological approach, we analyzed neural networks implicated in the processing of pitch and time. Cerebellar patients showed to be impaired in the perception of the time dimension but not for the pitch dimension. A study, with healthy listeners, concluded that the pitch dimension would be rather processed by the right hemisphere whereas no hemispheric advantage was observed for the time dimension. The findings of the studies are discussed in a neuropsychological model to explain the different stages of the processing of pitch and time

Full textThe teenagers approached in this study are placed in a Social Youth Center. To extricate the adolescent from any negative representations he may feel or of which he is the object in this particular context, due both to this affectation and of a Weak parental authority, we apprehend him neither through experienced failures nor those reminded to him, but through his own personal resources. To achieve this, we invite him towards a progression through pictorial creation and the encounter of the art world, followed by a personal production of wide dimensions and its public exhibition. Photographies of works taken at each step of their realization, enables to follow and assess the process of their making and the progression of their creator. This study is completed by a focus towards understanding the personality of each youth through series of expression tests (Rey’s Figure, AT9 and Rorschach). The search for discernment and aesthetic judgment brings the adolescent to a necessary adjustment between his own individual world and other artistic sensibilities. From this confrontation emerge images which might stimulate and widen his capacity of expression and representation of experienced time, at the same time that they participate in a process of personal evolution

Full textThis thesis deals with structural changes occurring in public companies that need to restructure their organisation in order to cope with European regulations. The issue of our study examines career management in public companies obliged to restructure. The topic of our research refers to career opportunities as perceived by the employees of such organisation in order to specify how career management has evolved further to the opening of some public markets. This work is composed of three parts. The first one consists of an overview of the literature, the second one deals with research methodology, and the last one highlights the results of this study. This qualitative research is based on two case studies (France Telecom and SNCB), carried out in two different countries (France and Belgium). The results, obtained thanks to three different analyses (thematic, textual and cognitive), underline that restructuring public companies leave slowly behind them the objective model of career management to reach a more individualizing model. The changes are mainly conducted in the "cadres” population and start slowly in the "non cadres” population. Moreover, the access to the "cadres” status is not possible depending on the structure in which they evolve. The employees see changes in their work conditions. Their career is now depending on the following criteria: length of service, willingness of the employee, the hierarchical superior's judgment and the internal promotions opportunities

Full textThis exploratory qualitative research analyzes the perception that skilled immigrants have of their employability. Ten Colombian skilled and qualified immigrants established in the city of Quebec were interviewed in order to identify what were the limiting factors and contributing factors that affected their employability, and the strategies they have used to find a job. The discourse analysis of the participant's interviews revealed that the professional expectations are at the center of the project to immigrate. Furthermore, this analysis reveals that despite the obstacles they must overcome to obtain the recognition of their qualifications, skilled immigrants are generally satisfied with the processes to integrate to the job market. Finally, the analysis identifies that skilled immigrants believe certain factors such as personal skills, fluency in the French language and professional field certainly contributed to successfully joining the workforce.
Esta investigación cualitativa de tipo exploratorio, analiza la percepción que los inmigrantes calificados tienen de su inserción profesional. Diez inmigrantes Colombianos calificados establecidos en la ciudad de Quebec fueron entrevistados con el fin de identificar los factores que limitan y que contribuyen a esta inserción, así como las estrategias que han utilizado para integrarse al mercado laboral. El análisis de los discursos de los participantes puso en evidencia que las expectativas profesionales están en el centro del proyecto de migración. Además, este análisis revela que a pesar de los obstáculos que deben superar para hacer reconocer sus títulos profesionales, las personas inmigrantes se sienten generalmente satisfechas de sus procesos de inserción. Finalmente, el análisis permite identificar que para los inmigrantes calificados ciertas predisposiciones como las cualidades personales, el manejo de la lengua francesa y el área de formación profesional son algunos de los factores que contribuyen a una inserción profesional exitosa.

Full textAThe objective of this research is to discover how the image of the body and object relation develop, furthermore, the ego development of congenitally blind people. Problematic: two approaches of blindness have been in confrontation. A pessimistic approach making vision the essential of knowledge, linking physical disability and sensory disability; A moderate vision, giving credit to haptic perception. What then about the body image and object relation? Starting with Lederman concepts, Anzieu and Tisseron, we onceived the idea of the gaze - skin. Hypothesis: The gaze - skin would allow, from the multimodal perception a recognition of the body image and the object; - and an access to the metaphor of desire as a relation to the desired object and its prohibition. Method: To get to confirm or disprove this hypothesis we used, the theoretical knowledge of developmental psychoanalysis, and methodologically, the semi-directive interview, and finally the creation of an observable experimental situation that we created because no visual experimentation was possible. The studied population included 20 congenitally blind people aged 18 to 21 years, which has enabled us to understand the state of blindness, and three young men blind from birth, who have been the subject of a case study, and were excluded those who became blind after a period of vision

Full textTeaching music in school academies has always been a recurrent issue. Is art meant to serve the learners' purpose or conversely, do learners have to comply to the rules of art ? There seems to be no clearcut decision that could close this debate. Since they have to face such a contradiction, learners, teachers and institution seem to be in a paradoxical and antinomic position which makes it hard to settle the matter. How can they solve such a dilemma ? With this aim in view, we will question music itself, using a play on words about the "säs" of music, something between the sense and the essence of music. We will study the sense of music through its three different meanings: its very meaning as regards language, its perspective as regards sociology, its sensation as regards phenomenology. Will this research, by giving some meaning to music, enable us unravel the paradoxical situations generated by music ? In a second part, we will attempt to get as close as possible to music by laying its sound on paper exactly like the written form (le säs) which perfectly renders the music heard in the words "sense" and "essence". For this purpose, we will translate the recording of a piano lesson into a score and we will attempt to reveal what is being woven between a teacher and his pupil. How do these two persons hear the music through the song of the piano ? And finally, we will unexpectedly find out that the musician's paradox can be solved through the practice of improvisation, thein-between, essential to expression and interpretation. In a sense, the essence of music might be hidden in the dephs of improvisation?

With this work we built a four steps methodological framework : outline research conception, empirical information collection, local knowledge building generic knowledge building and diffusion. In this empirical study, we achieved about sixty interviews, in four stores of a small Company. Moreover, we collected others informations (observations, documents). The interpretation of these gave rise to local knowledge building. Comparing this knowledge with existing theory, we built generic knowledge : - if we adopt a positive attitude toward athers, if organizationar goals are in phase with individual goals, extemal commitment and internal commitment could improve themselves in a recursive loop. Then, it is both interesting for individuals to live positively external commitment and to organization to improve their situation. - The " self " construction generic model built starting from Mead works could study dynamically both internal and external commifment - Dzjgereen between behaviors mutual upected and bemeen behaviors mutual perception could develop negative recursive loop - More individuals could interact in explicit communication, more they could feel recognized, more if could be possible to avoid the development of decommitment recursive loop. Then, we focused on knowledge diffusion. We started to make it use in an example

Full textThe importance of the automotive industry no longer has to be proven. Most of us own at least one car or know someone who owns one. The car is one of the most important singular household expenditures in the province Quebec, second only to housing. Thus, this purchase may involve a certain level of perceived risk for consumers since it is often necessary to pay a large sum of money to buy the car and we have no guarantee as to the reliability of the car, even more so for used cars. The main objectif of this project was to evaluate the influence of searching for information on the Internet on the perceived risk of buying a used car. Structural equations modeling was used to evaluate the relation between these two concepts. The primary results, based on a sample of 353 respondents, show that the more a consumer uses the Internet to search for information, the more he or she perceives a higher level of risk in relation to buying a used-car (ß = 0,176 ; p= 0,009 < 0,05). Furthermore, searching for information through social media also increases the perceived risk in regards to this specific purchase (ß = 0,348 ; p= *** < 0,001). These results raise questions in regards to the usefulness of searching for information on the Internet when looking to purchase a used-car.

Full textThe information system security for which the interest joins in the increasing dependence of companies to them information system and in prospect of increasing number of security incidents. We are interested in the information system risk management, for whom the literature underlines the lack of involvement of top-managers.We approach the concern under the view of the decision of top executives for ISS, through four theoretical streams: the models of the managerial perceptions of IS risks, the risks perception in psychology, the institutional theory and the theory about symbolic adoption of the innovations. The aim is to make intelligible the influences on the symbolic adoption of such ISS approach. We use a qualitative method organized around 17 case studies in companies with varied activities. Our results highlight the relevance to study the ISS according to an individual perspective of risk management. On one hand, the characteristics of the psychological evaluation of the risks enlighten the biases for the management of the information system risk. On the other hand, the study of these biases brings a new perspective on the understanding of the investment of the top executives for the ISS. In particular, we underline the insensitivity of the top managers in the exposure of the risk, a preference to approach the risks under a threats point of view. We expose the influences which contribute to adopt a technical and not managerial ISS such as suggests by the Research. Finally, our analysis brings to the foreground perspectives to extend the comprehension of a reactive ISS, defame by ISS’ academics

Full textAvailable literature suggests that dyslexia is a learning disability that is neither linked to mental retardation, not to sensory disorder nor to deprived social background. The dyslexic child shows a difference of 18 to 24 months between the academic achievement of a reading subject and his or her intellectual potentials as measured by an intelligence scaling (IQ). The child suffers from brain structure dysfunction which impedes his cognitive abilities resulting in wrong word identification. We also know that the diagnosis is based on the evaluation of speech, reading and writing abilities. In our work, we focus on child phonological dyslexia. The latter is mainly characterized by impaired phonological route due to poor development of phonological ability. In reality, dyslexic children have a higher intra-categorical sensitivity rather than an inter-categorical perception. If we accept the idea of coupling between speech production and perception, we can posit the existence of a perturbation in the articulatory realisation of speech produced by dyslexic children which explains both their delayed speech and language disorder. Indeed, speech is governed by a number of phonetic and phonological rules; the variation of a coarticulated phoneme is at the root of difficulty of phoneme discrimination encountered by dyslexic children. This coarticulated phoneme has several allophones. We suggest that the articulatory variability of a single phoneme is the main cause of speech impairment. We performed an analysis of their verbal production in search of the articulatory markers that differ from children with no learning disability. With this in mind, we conducted four studies dealing with different sequences (CV, CVCV, and VCVCV VCVCCV). Tasks included reading words and pseudo-words, aloud and at normal speech rate. The measured parameters studied as regards acoustic cues for stops were VTT, the acoustic silent phase and VOT for voiceless stops; occlusion and VOT for the voiced stops, and duration for flanking vowels. During word identification, analyses reveal that the phonological route may be partially operational for our subjects. They also reveal partial or total word deformation; voicing contrast and place of articulation contrasts were also affected. Note should be taken of the higher measures found in dyslexic children than in normal readers, reflecting a slower gestures in their articulatory realizations due to additional time needed in these children. In addition, these parameters do not often follow a coherent pattern of proportional values relative to the requirements imposed by the characteristics of place of articulation and signal quality. However, we find that word intelligibility could be maintained. This experimental study has demonstrated the link between perception and articulation disorder, and to some extent speech and language production impairment
