Cette thèse contribue à la littérature économique sur les compétences non cognitives essentielles pour la réussite de la vie, particulièrement pour la réussite scolaire. Elle comprend quatre essais basés sur des approches économiques comportementales et expérimentales, avec deux objectifs principaux. Le premier objectif est d’étudier deux compétences non cognitives, à savoir la confiance en soi et la créativité. Notre but est alors de comprendre les déterminants de la confiance en soi et l’impact de la créativité sur les résultats économiques. Le deuxième objectif est d’étudier comment le système scolaire influence les décisions éducatives, les résultats scolaires et la mobilité intergénérationnelle, secteurs où les compétences non cognitives peuvent jouer un rôle important, en particulier via leurs effets sur la confiance en soi et la motivation. Nous observons un impact important des capacités non cognitives sur le comportement et sur les résultats économiques, notamment en ce qui concerne les décisions éducatives. Tout nous montre à penser que fondamentalement les écoles s’inquiètent du développement de ces capacités non cognitives - et non pas seulement des capacités cognitives. Aider les élèves à avoir de meilleures estimations de leur confiance en soi, favoriser le développement du potentiel créatif, stimuler la motivation et l’effort devraient alors faire partie de l’éducation que les élèves reçoivent dans les écoles ; promouvant alors de meilleures décisions, de meilleurs résultats et une société plus équitable. / This thesis contributes to the growing economic literature on noncognitive skills that are critical for life success, specially for academic success. It comprises four essays based on behavioral and experimental economics approaches, with two main objectives. The first objective is to study two noncognitive skills, namely self-confidence and creativity. We aim at understanding the determinants of self-confidence, and the impact of creative potential on economic outcomes. The second objective is to study how school systems impact educational decisions, educational outcomes and intergenerational mobility, where noncognitive skills may play an important role, specially self-confidence and motivation. We observe an important impact of the noncognitive abilities on behavior and economic results, especially for the educational achievements. Taken all our evidences together, it seems fundamental that schools worry about the development of these noncognitive abilities - and not only of the cognitive abilities. Helping students to have better estimates of self-confidence, favoring the development of creative potential, and stimulating motivation and effort should be part of the education that pupils receive in schools ; promoting then better decisions, better outcomes and a more equitable society.

O propósito deste trabalho é investigar os antecedentes do comportamento de retaliação dos consumidores. Primeiramente, revisam-se os fundamentos teóricos relativos ao tema. A seguir, apresenta-se a metodologia empregada, ressaltando-se as quatro etapas de pesquisa realizadas. Na primeira, qualitativa, foram realizadas 27 entrevistas em profundidade, que deram origem ao questionário e aos cenários das etapas experimentais do estudo. Na segunda, foi aplicado o primeiro experimento com o objetivo de examinar os efeitos do nível de insatisfação e das demais variáveis dependentes (autoconfiança, valência, eficácia de mercado e tendência por agressão deslocada) na intenção de retaliação em dois momentos diferentes: pós-insatisfação inicial (RPII) e pós-insatisfação com o gerenciamento da reclamação (RPIGR). A autoconfiança e a tendência por agressão deslocada emergiram como fortes moderadores da relação entre nível de insatisfação e intenção de retaliação. A valência indicou exercer efeito mediador nessa relação. A eficácia de mercado não influenciou a intenção de retaliação. Ainda, como os resultados do primeiro experimento indicaram que a retaliação é um fenômeno bem mais prevalente em situações de insatisfação pós-recuperação de serviço, o segundo experimento investigou os efeitos das percepções de justiça (distributiva, processual e interpessoal) e da iniciativa de recuperação (pela empresa vs. pelo consumidor) na intenção de retaliação. Os resultados confirmam as hipóteses do estudo e reforçam a existência da interação das dimensões de justiça na predição da intenção de retaliação. Os efeitos moderadores da autoconfiança e da tendência por agressão deslocada foram confirmados também no segundo experimento. Por outro lado, o papel mediador da valência foi rejeitado. No terceiro experimento, uma explicação adicional para o fenômeno de retaliação foi testada (influência social). Os resultados do terceiro experimento replicam os resultados do segundo e confirmam parcialmente a hipótese da influência social na intenção de retaliação. Não existiu diferença significativa na intenção de retaliação quando somente o próprio entrevistado é injustiçado do que quando ele observa outros indivíduos serem injustiçados ou quando ele sofre e observa alguma injustiça. Esses resultados fornecem uma série de implicações gerenciais e acadêmicas, bem como abrem caminho para futuras pesquisas. / The intention of this work is to investigate the antecedents of the consumer retaliatory behavior. First, the theoretical basis concerning the theme was reviewed. Next, the methodology applied was presented, emphasizing the four phases of research. In the first, qualitative phase, 27 in depth interviews were made, originating the structured questionnaire and the scenarios of the experimental phases of the study. In second phase, the first experiment was applied with the objective to examine the effect of the dissatisfaction level and the other dependent variables (self-confidence, valence, market effectiveness and trait of displaced aggression) in the intention to retaliate at two different moments: after an initial dissatisfaction (RPII) and after a dissatisfactory complaint handling (RPIGR). The selfconfidence and trait of displaced aggression emerged as strong moderators to the relation between dissatisfaction level and intention of retaliation. The valence exerted a mediating effect in this relation. The market effectiveness did not influence the retaliation intention. Still, as the results of the first experiment had indicated that the retaliation is a phenomenon well more prevalent in dissatisfaction after service recovery situations, the second experiment investigated the effect of the perceptions of justice (distributive, procedural and interpersonal) and of the recovery initiatiation (by the company vs. by the consumer) in the retaliation intention. The results confirm the hypotheses of the study and strengthen the existence of the interaction of the dimensions of justice in the prediction of the retaliation intention. The moderator effect of the self-confidence and of the trait of displaced aggression was also confirmed in the second experiment. On the other hand, the mediating role of the valence was rejected. In the third experiment, an additional explanation for the retaliation phenomenon was tested (social influence). The results of the third experiment replicate the results of the second one and partially confirm the hypothesis of the social influence in the retaliation intention. There was no significant difference in the intention to retaliate between the groups that the own partcipant in the experiment is victim of an injustice, that he or she only observes other individuals to be victims of an injustice and that he or she suffers and observes an injustice. These results supply several managerial and academic implications, as well as they open a new agenda for future research.

The thesis deals with the issue of singletons. Its main question is directed to the childhood of singletons and its importance for the whole life of a human. It wonders whether the childhood of singletons affects humans in adulthood, or in which areas and which way. The thesis is divided into two parts, theoretical and part of the research. In the first part basic terms are defined which constitute the basis for the second part of the work. The research part of the work is more extensive and forms the core of the thesis. It is a qualitative research. Biographical design, specifically the realistic biography, has been used as the most appropriate research plan. First, three interviews were made and processed - depth probes of the respondents who grew up as the singletons. The analysis of the probes divided the interview into three stages: childhood upbringing, the upbringing of their own children and self-education. After processing the individual parts of the research, the final synthesis revealed that the childhood of the respondents and the fact of being an only child had a significant impact on their overall life. It affected their childhood and also the following life stages. The biggest deficit of the singletons was in socialization, predominantly in the area of interpersonal relations and...

En systematisk litteraturstudie om vilka faktorer som kan orsaka matematikängslan hos elever i grundskolan och hur lärare kan arbeta för att stärka elevernas självförtroende och hjälpa dem att minska denna ängslan. Vi människor föds inte med matematiska förmågor och automatiskt blir antingen bättre eller sämre på matematik, utan vi utvecklas och lär med tiden att bli matematiska. I studien lyfts normer och attityder till matematik fram och problematiseras i samband med elevers matematikängslan. Studiens resultat visar att det framför allt är yttre sociala faktorer,normer och negativa handlingar som påverkar elevers matematikängslan. Detta kan leda till att elever utvecklar ett lägre självförtroende och negativa attityder till ämnet matematik. Det kan därmed vara svårt att bryta detta då det blir en negativ spiral, vilket kan resultera i att elever ser på sig själva som mindre matematiska. Men genom att bygga bra lärar-elev-relationer, stärka elevens självförtroende och skapa positiva attityder och goda normer till ämnet matematik så 3kan lärare hjälpa eleven att minska denna ängslan. Därför ligger ett stort ansvar på att lärare utvecklar kunskaper i hur de kan bemöta elever med matematikängslan. / A systematic literature review on factors that could cause math anxiety in primary school students and how teachers can work to strengthen students' self-confidence and help them reduce this anxiety. We humans are not born with mathematical abilities and automatically become either better or worse at mathematics, but we develop and learn over time to become mathematical. We highlight norms and attitudes to mathematics in the study and problematize them in connection with students' mathematics anxiety. The results of the study indicate that it is most social factors, norms and negative acts and comments that affect students' math anxiety. This leads to developing lower self-confidence and negative attitudes towards the subject of mathematics. This could be difficult to break as it becomes a negative spiral, which results in the student seeing themselves as less mathematical. But by building good teacher-student relationships, building the student's self-confidence, and creating positive attitudes and good norms towards the subject of mathematics, teachers can help the student to reduce this anxiety. Therefore, teachers have a responsibility to learn how they can help students with math anxiety.

Bakgrund: Trots den synliga framgången inom idrotten kan tävlingsångest vara en dold utmaning som potentiellt påverkar prestationen negativt. Könsskillnader på tävlingsångest är komplicerad och kan härledas till en kombination av biologiska, psykologiska och sociokulturella faktorer. För att hantera tävlingsångest och optimera prestationen kan flera metoder tillämpas för mental träning, som visualisering, coping-strategier, mindfulness och self-talk. Genom att förstå och hantera tävlingsångest kan atleter uppnå bättre resultat och bidra till en hälsosammare idrottsmiljö. Syfte: Syftet med denna studie är att belysa eventuella könsskillnader på upplevelsen av tävlingsångest hos atleter. Studien syftar även till att belysa potentiella faktorer som påverkar tävlingsångest samt potentiella åtgärder för att minska tävlingsångest hos atleter. Metod: Studien är en strukturerad litteraturöversikt med en deskriptiv ansats. Fyra olika databaser (Medline, APA PsycInfo, Scopus, Cinahl) användes för att inhämta relevant litteratur, vilket resulterade i inkluderingen av totalt tretton artiklar. Resultat: Resultaten tyder på att kvinnliga atleter rapporterade högre somatisk och kognitiv ångest samt lägre självförtroende än manliga atleter. Även ålder och erfarenhet är avgörande faktorer för tävlingsångest. Äldre och mer erfarna atleter visade lägre nivå av både somatisk och kognitiv ångest samt högre självförtroende. Flera åtgärder utforskades för att hantera tävlingsångest, inklusive self-talk och mental träning, vilket visade sig vara effektivt för att minska tävlingsångest och öka självförtroendet hos atleter. Slutsats: En väsentlig betoning läggs på att individualisera interventioner för att hantera tävlingsångest utifrån enskilda behov och förutsättningar. Dessutom identifieras könsskillnader och individuella skillnader i upplevelsen av tävlingsångest, vilket bidrar till utformningen av skräddarsydda och effektiva stödåtgärder för atleter. För framtiden förespråkas en ökad forskningssatsning i Sverige där forskningsläget är otillräckligt.

Cette thèse se concentre sur trois aspects très différents de l'éducation mais qui affectent chacun la qualité de son offre. Dans le premier chapitre, nous étudions le comportement stratégique adopté à la fois par l'université et par les professeurs, afin pour les uns d'attirer les meilleurs universitaires et pour les autres d'accéder aux meilleures positions, en faisant un compromis entre salaires élevés, sécurité de l'emploi et possibilités de mobilité ascendante. Dans un deuxième chapitre, nous étudions comment la répartition des revenus dans les districts scolaires affecte la qualité des écoles publiques, par la voie des votes locaux et de la fiscalité. En effet, un district scolaire avec une polarisation de revenu plus élevée conduit à un vote pour une faible taxation et donc de plus basses dépenses pour l'école publique impliquant une moins bonne qualité de cette dernière. Enfin, dans un dernier chapitre, nous montrons que les attentes des garçons et des filles concernant leurs futures carrières ainsi que les antécédents scolaires sont façonnés par des stéréotypes de genre. Par exemple, le stéréotype selon lequel les hommes sont meilleurs en mathématiques crée un stéréotype négatif sur les aptitudes des filles en mathématiques. Les stéréotypes représentent l'explication principale dans les différences entre les garçons et les filles en matière de confiance en soi et ont des conséquences importantes sur les chemins qu'ils suivent tout au long de leur vie. / This thesis focuses on three very different aspects of education but which all affect in their way the quality of its provision.In the first chapter, we investigate the strategic behavior adopted by both the university and the professors, in order, for the first to attract the best academics, and for the second to access the best positions making a trade-off between high salaries, job security and upward mobility possibilities. We question the efficiency of such system in attracting, but also in keeping, the best academics. In a second chapter, we investigate how the income distribution of school districts affects the quality of public schools through the channel of local votes and taxation. In fact, an income polarized school district (more poor and rich at the expense of the middle class) leads to a vote for low taxation and thus low expenditure toward public school and a poorest quality of school. The mechanism being that the richest households send their children to private schools and thus are not concerned by public school quality while poorest households can not afford a too high taxation.Finally, in a last chapter we show how boys' and girls' career expectations and educational background are shaped by gender stereotypes. For instance, the stereotype that men are better at mathematics creates a negative stereotype on girls aptitudes in mathematics. Stereotypes represent the main explanation in boys and girls differences in self-confidence, and have important consequences on the paths they take throughout their lives.

This Study elaborates the topic of Biblical Trust in the World of Pentateuch. This trust is understood as to rely in a purely subjective way on a word or instruction of some person. In case of God it frequently means a conviction that some humanly unrealizable promises are to be fulfilled. Such attitude secures to the trusting person merits before God. Rely on God is often understood in a confrontational way as opposite to the life of unbelievers. Trust requires courage to make leap in the dark. Meanwhile it is always right to trust in God, trust in a human person is in Pentateuch interpreted as fool. But if the respective man is the spokesman of God, the eventual mistrust is seen as an attack against God himself. In case of God's revelation trust becomes duty. If there is any doubt people can ask some sign of authenticity for the presented God's will. But if the will is known, eventual mistrust is interpreted as disobedience and follows a severe punishment. The same trust which belongs to God is required also for his prophet and for the Law proclaimed in the God's name. If somebody relies on himself in sense of exaggerated self-confidence which does not count on God, it is understood as a crime. In the same manner is valuated the trust directed towards the pagan divinities.
