Cette recherche se propose trois objectifs : il s’agit, premièrement, de dégager les représentations et les causes que les patients tunisiens attribuent à la pathologie cancéreuse. Deuxièmement, de déceler les croyances en matière de contrôle perçu pour ce qui est de l’évolution de la maladie. Enfin, de chercher l’effet direct, médiatisé ou modéré d’un ensemble de variables personnelles, médicales et environnementales sur le coping de ces patients. Les résultats auxquels nous avons abouti, au moyen d’une étude quantitative, mettent en évidence l’effet direct du niveau socio-culturel du patient sur le choix du coping centré sur le problème. Cet effet se trouve médiatisé partiellement par un Lieu de contrôle-médecin, un fort sentiment d’efficacité personnelle et une tendance vers l’optimisme. En outre, une étude qualitative a fait émerger des notions comme celle d’optimisme réaliste, du coping religieux et de la croyance en un monde juste. De tels résultats sont en faveur de la conception et de la mise en place de programmes de formation et de développement des ressources humaines afin de promouvoir le système de santé du pays. / This research proposes three objectives: the first one consists in bringing out the representations and the causes that the Tunisian patients attribute to the cancerous pathology. The second is to identify the beliefs concerning the perceived control of the disease evolution. Finally, the third objective is to seek the direct, mediate or moderate effect of a set of personal, medical and environmental variables on the coping of these patients. The results which we have come to, by means of a quantitative study, highlight the direct effect of the socio-cultural level of the patient on the choice of the problem-focused coping. This effect is partially mediated by a doctor-health locus of control, a strong personal perceived efficacy and a tendency towards optimism. In addition, a qualitative study has led to the appearance of notions such as realistic optimism, religious coping and belief in a just world. Such results support both the conception and the establishment of programs for the training and the development of human resources in order to promote the country's health system.

Earlier studies in the context of windows and blinds selection have mostly tried to increase the awareness regarding various effects of windows and blinds selection on subjective well-being, including their effect on visual comfort, thermal comfort, energy consumption and life cycle cost. However, the main problem is the potential conflicts between visual comfort, thermal comfort, energy consumption and life cycle cost. Increased awareness about the contradictory effect of windows and blinds selection on subjective well-being on one hand and lack of a feasible method in managing the conflicts on the other hand may bind individuals, as decision-makers, in a situation where they follow the immediate economic benefits rather than the long-term visual and thermal benefits. To solve the mentioned problem, this study analysed first the degree of the conflicts between average daylight illuminance and total energy consumption in Sweden. This decision was made due to large variation in solar elevation angle and solar intensity between summer and winter in Sweden, which has significant effects on daylight illuminance and total energy consumption. Analysing the conflicts was accomplished by developing two multivariate linear regression models for calculating average daylight illuminance and total energy consumption. Comparison and analysis of the multivariate linear regression models showed the existence of a high degree of conflicts, which makes window and blind selection a rather complex multidimensional problem. Specifying the degree of the conflicts formed a hypothesis as: “A multi criteria decision-making method increases the controllability and manages the conflicts in selecting windows and blinds”. The developed hypothesis was later tested by employing analytical hierarchy process, as widely used multi criteria decisionmaking method. The analytical hierarchy process prioritizes decision-maker’ preferences and introduces a desired trade-off solution. The results of employing analytical hierarchy process showed the capability of it in managing the conflicts among visual comfort, thermal comfort, energy consumption and life cycle cost. Finally, the application of the analytical hierarchy process was expanded by integrating it with nondominated sorting genetic algorithm-II, as an optimization algorithm. Through this integration, optimization algorithm combines windows’ and blinds’ design variables and analyses a large number of solutions, while analytical hierarchy process ranks the solutions based on decision-makers’ preferences and introduces a desired trade-off solution. The integration between analytical hierarchy process and the nondominated sorting genetic algorithm-II was presented later as a conceptual framework. The developed conceptual framework can be used for selecting windows and blinds II in both residential and commercial buildings. In selecting windows and blinds, the conceptual framework is a novel solution to the lack of a feasible method for increasing the controllability for decision-makers and obtaining a desired trade-off solution. / Tidigare studier avseende val av fönster och solskydd har främst försökt fastställa olika effekter som valet av fönster och solskydd har på det subjektiva välbefinnandet. Detta inkluderar dessa föremåls effekt på den visuella komforten, den termiska komforten, energiförbrukningen och livscykelkostnaderna. Det huvudsakliga problemet är dock de potentiella konflikterna mellan visuell komfort, termisk komfort, energiförbrukning och livscykelkostnader. Avsaknaden av en metod för att hantera denna konflikt leder till att beslutfattaren fastnar i en situation där de snarare gör sitt val utifrån omedelbara ekonomiska fördelar än de långsiktiga visuella och termiska fördelarna. För att lösa ovan nämnda problem analyserades konflikterna mellan det genomsnittliga dagsljusinsläppet och den totala energiförbrukningen i Sverige. En av huvudanledningarna till konflikterna är att solens infallsvinkel och intensitet varierar kraftigt mellan sommar och vinter i Sverige. Detta har betydande effekter på dagsljusinfallet och den totala energiförbrukningen. Konflikterna analyserades genom att utveckla två multivariata linjära regressionsmodeller för att beräkna det genomsnittliga dagsljusinfallet och den totala energiförbrukningen. En jämförelse och analys av de multivariata linjära regressionsmodellerna påvisade en hög grad av konflikter, vilket gör valet av fönster och solskydd till ett komplext och flerdimensionellt problem. Bestämningen av graden av konflikt formade följande hypotes: ” En multikriterieanalysbaserat beslutsstöd ökar kontrollerbarheten och hanterar konflikter vid valet av fönster och solskydd”. Den utvecklade hypotesen testades senare med hjälp av Analytical Hierarchy Process (AHP), en ofta använd multikriterieanalys metod för beslutsfattande. Metoden tar fram lösningar genom att göra prioriteringar enligt beslutsfattarens preferenser. Resultaten av att tillämpa metoden visade metodens förmåga att lösa konflikterna kring visuell komfort, termisk komfort, energiförbrukning och livscykelkostnad. Slutligen utökades metoden genom att integrera AHP med optimeringsalgoritmen Non-dominated sorting genetic algorithm-II. Genom denna integrering kombinerar optimeringsalgoritmen fönstrens och solskyddens design variabler till ett stort antal lösningsförslag. Dessa lösningsförslag analyseras och till sist rangordnas lösningsförslagen med hjälp av AHP baserat på beslutsfattarnas preferenser. Integreringen av AHP och optimeringsalgoritmen presenterades som ett konceptuellt ramverk. I valet av fönster och solskydd är det konceptuella ramverket en ny lösning för att öka den upplevda kontrollen och därmed förstärka det subjektiva välbefinnandet. / ProWood

Bakgrund: Stressrelaterade sjukdomar har blivit allt vanligare i Sverige. Stress är kopplat till flertalet sjukdomar, psykisk ohälsa och smärta. Meditation i olika former har visat sig påverka ett flertal funktioner i hjärnan positivt, och kan ha en stressreducerande effekt hos människor. Problemformulering:Få studier har undersökt den subjektiva upplevelsen av stress i samband med meditation. Att minska och förebygga stress är intressant ur ett fysioterapeutiskt perspektiv då stress kan försämra hälsa. Syfte:Att undersöka om meditation kan ha en stressreducerande effekt för ett mindre antal meditationsutövare med ingen eller liten erfarenhet, under fem veckor. Metod: Tre personer fick skatta upplevd stress dagligen genom en modifierad version av PSS-14 bestående av tre frågor under baslinje och intervention som berör upplevelsen av stress och nervositet, irritationsmoment och känslan av att kontrollera viktiga saker i livet. Interventionen bestod av en nybörjarkurs i en stilla meditationsform fördelat på fyra kurstillfällen bestående av teoretisk och praktisk undervisning samt 45–60 minuters meditationsutövande dagligen. Antal minuter som mediterats besvarades också dagligen. Resultat:Upplevelsen av stress och nervositet minskade, förmågan att hantera irritationsmoment ökade och känslan av att inte ha kontroll över viktiga saker i livet minskade hos samtliga deltagare. Ingen tydlig skillnad observerades mellan självskattning av de tre aspekterna hos varje enskild individ under interventionen. Konklusion:Meditation kan ha positiva effekter på alla tre aspekterna av stress. Andra metoder som multipel baslinje-design, längre baslinje och strategier för att fånga upp externa faktorer hade behövts, vilket kunde ha producerat mer trovärdiga resultat. / Background:Cases of stress-related disorders have increased in Sweden. Stress is related to several diseases and mental illness and could cause or aggravate pain. Meditation has previously shown positive effects on brain functioning and could reduce perceived stress. Problem: Few studies have examined the subjective experience of stress in association with meditation. To reduce and prevent stress is of interest from a physiotherapeutic perspective, as stress could deteriorate health conditions. Purpose:To examine if meditation during five weeks could reduce stress in a small number of meditation-practitioners with no or little experience. Method:Three participants assessed perceived stress using a modified version of the PSS-14 existing of three questions during baseline and intervention concerning the sensation of stress and anxiety, sources of irritation and the ability to control important things in life. The intervention included taking part of a beginners’ course in sitting meditation including four course meetings consisting of both theoretical and practical teachings and 45-60 minutes of meditation practice daily. Results:Perceived stress and anxiety were reduced, the ability to control irritations in life was improved and the feeling of being unable to control important things in life was reduced in all participants. No distinct differences were noted between assessments of all three aspects of stress in every individual separately. Conclusion: Meditation could havepositive effects on all three aspects of stress. Other methods such as multiple baseline design, longer baseline and strategies to identify external factors should have been used which might have produced more credible results.

Background: The society has changed and become increasingly characterized by technology-facilitated interactions. Companies are starting to make use of self-service. technologies (SSTs), instead of interpersonal encounters during service deliveries. Customers’ usage of SSTs has been examined in previous research. However, previous studies have ignored the fact that different types of SSTs have different factors that influence customer's experience and decision to use them, increasing the relevance of examining one specific SST, namely private SST to achieve more accurate results regarding what specific factors that influences customer decision to use this type of SST. The reason for choosing private SSTs is not only because it is the most recent type of SST, it is also the type of SST that develops continuously with the increased use of the Internet and the World Wide Web. Purpose: The purpose of this research is to identify the most important factors influencing customers to use private SST. Research Questions:- What value judgement influences customers to use private SSTs the most? - What factors influences customers’ value judgements? Methodology: This research takes on a quantitative approach with an explanatory research design. The chosen data collection method is performed through one independent survey. Conclusion: Hedonic and utilitarian value judgements have a positive relationship towards customer's decision to use private SSTs. The utilitarian value judgements have a greater impact on customer's decision to make use of private SSTs, in comparison to the hedonic value judgements. However, hedonic value judgements can still be considered as an important factor in influencing customer's decision to use private SSTs, as the hedonic value judgements still have a relatively strong impact on customer's decision to use private SSTs.

Cette thèse fournit des éléments pertinents dans la prédiction de l'intention d'usage d'un progiciel de gestion intégrée (PGI) dans le secteur de transport aérien en Tunisie. L'introduction de ce type de progiciel implique des changements au niveau de l'organisation du travail et des appréhensions au niveau des salariés en regard de sa complexité. Le premier objectif empirique de ce travail est de relever les rôles respectifs du sentiment d'auto-efficacité, le sentiment de contrôle comportemental perçu et la charge subjective du travail dans le choix d'adoption de ces progiciels (étude 1). Les résultats indiquent qu'une synergie est bien présente entre les éléments indiqués et qu'ils influencent de manière significative le recours à l'utilisation des PGI. L'auto-efficacité informatique et le contrôle perçu favorisent l'intention le recours à l'usage des PGI de manière directe et indirecte via les perceptions d'utilité et d'utilisabilité relatives au progiciel. Tandis que la charge subjective de travail entrave le recours à l'utilisation de cet outil. Les composantes de la charge subjective de travail (la charge mentale, la charge temporelle, la demande en effort et en performance et la frustration) ont ainsi un poids considérable dans la formation de l'intention d'usage de ce progiciel. La principale source de cet effet négatif est due au sentiment de frustration que pourrait ressentir le salarié lors de l'usage d'un PGI. L'étude des différentes formes de la frustration (étude 2) suggère un impact plus important du sentiment de découragement que le sentiment de stress perçu sur l'utilisabilité et l'intention d'usage des PGI. Cette présente thèse a un double objectif : une contribution théorique sur le rôle des déterminants émotionnels sur l'intention d'usage des progiciels de gestion intégrée et une contribution pratique puisque ce travail permet de repenser la décision d'investissement en l'implémentation du progiciel et canaliser les efforts des formateurs afin de diminuer la charge subjective chez les salariés lors de l'utilisation effective de l'outil. / This thesis provides us with relevant factors which served as predictions of intentions used through Enterprise Resource Planning (ERP) in the air transport sector in Tunisia. The introduction of such type of package implies changes in work's organizations and employees' apprehensions since it is to be considered as a complex process. The first empirical objective of this work is to pinpoint respectively the main role of the sense of self-efficacy, the perceived behavioral control and subjective workload in choosing adoption of such packages (study 1). The results indicate that interrelatedness is well marked and therefore, it has a significant influence in the use of the ERP. Both computer's self-efficiency and experienced self-control lead to a direct or indirect use of ERP through the perceived utility and relative usability of the package. Whereas, the subjective aspect of the workload go against a good use this tool. The components of subjective workload (mental workload, temporal workload, asked efforts, performance's level and frustration) have considerable effect in the formation of good willingness for the use of such software. This experienced negative effect stems its origins from the employee's frustration when using an ERP system. The study of different forms of frustration (Study 2) suggests that a greater impact is to be recorded, and then, a feeling of discouragement is far to be dismissed and it can be considered as more important than the perceived stress related with usability of the ERP. The present thesis has two layers of research: the first is a kind of theoretical contribution on the role of emotional determinants on the intentional use of ERP systems and the second is a practical contribution since it paves the way to a rethinking of the decisional invest in the implementation of such a package's in-put and therefore it mainstreams the effort of educators in the aim to reduce the subjective burden among employees during an actual and efficient use of the tool.

The current research considered parent report of sleep problems in children with an intellectual disability (ID). Of specific interest were parents who reported child sleep issues/disturbances but who did not consider their child to have a sleep problem. Also of interest was the use of a general parent-training program to treat both the sleep and behaviour problems in children with an ID. Study 1 examined parent perceptions regarding sleep in children with an ID. Parents who reported a child sleep problem provided information on the types of sleep treatment tried and rated their effectiveness. Overall, 243 questionnaires were completed by parents of children with a range of disabilities aged between 3.1 to 18.7 years. While 62% of parents rated their child as displaying problematic night settling, night waking, early waking, or other disturbing sleep behaviours, only 27% of parents considered their child to have a sleep problem. A higher number of parents (75%) than expected had tried at least one type of intervention, although it was not possible to discern 'self help' treatments from 'professionally sought' treatments. Study 2 investigated child and parent factors associated with parent perception of sleep problems in children with an ID. Seventy-six parents from Study 1 completed measures in relation to child adaptive and daytime behaviour, parent stress, locus of control, personality (extraversion, neuroticism, and psychoticism), parenting competence, and perceived control over the child's sleep and daytime behaviour. Based on parent report on a sleep measure and response to the question 'do you think your child has a sleep problem' parents were allocated into one of three sleep groups: Parents who recognised a sleep problem (RSP, N=20), parents whose child did not have a sleep problem (NSP, N=35), and parents who did not recognise their child to have a sleep problem (USP, N=21). The results revealed differences between parents who do (RSP) and parents who do not (USP) recognise their child's sleep problem. These differences related to amount of child sleep (as reported by parents) and parent perceived control over the child's sleep and daytime behaviour. Study 3 examined the efficacy of a general parent-training (behaviour management) program, with sleep used as the training exemplar, for the treatment of sleep problems in children with an ID. Of the 20 parents in the RSP group in Study 2, five agreed to take part in Study 3 and three completed the intervention. The effect of the intervention on (a) a targeted sleep problem, (b) a targeted behaviour problem, (c) other sleep and daytime behaviours, (d) parent stress, (e) parent sleep, (f) parent sense of competence, and (g) parent perceived control over the child's sleep and daytime behaviour were examined. All parents reported an improvement in target sleep behaviour, and at follow-up all of the parents no longer considered their child to have a sleep problem. One parent reported a decrease in stress and an increase in measures of perceived control, and parenting competence, while two parents showed minimal to no improvement on child and parent outcomes.

In this thesis, pre-school teachers’ perceived control, is examined in relation to problem behaviours of children and the actions of teachers in the classroom. In addition, other factors that are thought to relate to teachers’ perceived control were studied. The results of Study I indicate that pre-school teachers’ high perceived control was related to high intentions to act in the event of child behaviour problems. Teachers’ high satisfaction with their work was also related to high perceived control. Study II showed that low perceived control was associated with having a high proportion of children with a high level of externalising behaviours and of boys in the classroom. Study III shows that children who had a high level of externalising behaviours at the beginning and throughout the school year had teachers with low perceived control. Teachers’ perceived control was not related to their perception of internalising behaviours in the same way as to externalising behaviours and it was unrelated to a change in any direction of problem behaviours. Concerning changes in problem behaviours, no other factor was found, except a low child to adult ratio for a positive change of internalising behaviours. In Study IV, the aim was to examine naturally occurring child–teacher interactions. Teachers’ responding with commands to children was associated with teachers’ low perceived control, whereas restrictive teacher responses were not related to teachers’ perceived control. The present study indicates that teachers’ perceptions of children are important for their perceived control. It provides evidence that teachers’ low perceived control is associated with their difficulties in handling externalising behaviours and the behaviour of the boys in the classroom. Responding to problem behaviours can be explained by teachers’ perceived control, and their perception of a child’s sex and externalising behaviours.

Title: Attitudes and motivations of young people towards sport betting Objectives: To find out which factors significantly influence sport betting in young Czechs between the age of 18 and 30. Methods: Due to the quantitative nature of the research, the only used method was electronic survey. The survey was based on the theory of planned behaviour. It primarily sought information on independent variables (predictors) within this theory, which are attitudes, subjective norm and perceived control (in connection with sport betting). This part was adopted from a similar previous research. The intention and behaviour of the respondents as response variables were also surveyed in order to describe the relationships between independent and response variables. The sample consisted of 122 respondents, mostly active betters. Statistical methods such as correlation and regression analysis were used, followed by a final path analysis, which provided a model visualizing the relationships between the crucial variables. Results: All of the examined predictors within the theory of planned behaviour influence the intention to bet - the values are 0,241 for attitudes, 0,335 for subjective norm and -0,410 for perceived control. The negative value means that those with higher perceived control have lower intention to...
