Research pertaining to personality traits has largely focused on broad dimensions that define personality configurations, rather than on specific actions and behaviours that people engage in every day. While trait theorists hold the belief that individuals' personality traits predict their behaviours, there is no thorough conceptualization of behavioural manifestations of personality traits in the existing literature. The first goal of the present dissertation was therefore to conceptualize a model of behavioural manifestations of the Five Factor Model (FFM) traits. To achieve this goal, in the first article, a taxonomy of behavioural expressions of FFM traits was operationalized through the development of an instrument: the Behavioural Expressions of Traits Inventory (BETI). Results from Study 1 (N = 454) and Study 2 (N = 297) validated the proposed taxonomy by means of both exploratory and confirmatory factor analyses. The final version of the BETI comprised 30 items (6 items/subscale) that presented a clean factor structure. Concurrent validity results revealed that the taxonomy of behavioural expressions could be distinguished from FFM traits. The BETI also displayed good construct validity, satisfactory internal consistency values of all subscales, and no issues with social desirability. The second goal of this dissertation was to use this conceptualization of behavioural expressions of traits advantageously to examine an important fundamental topic: the processes at play in the associations between FFM personality traits and motivation through the lens of Self-Determination Theory (SDT). Results from emerging studies consistently revealed positive associations between beneficial FFM traits (openness to experience, conscientiousness, extraversion, and agreeableness) and autonomous motivation. Conversely, negative associations were obtained for neuroticism, a detrimental trait. The second article of this dissertation aimed to further our understanding of the associations between FFM traits and autonomous motivation by examining two potential mediators of this relationship: behavioural expressions of FFM traits and basic psychological need (BPN) satisfaction, a well-known antecedent of autonomous motivation. Two motivation domains central to the lives of undergraduate students were examined: academics and friendship. In Study 3 (N=635), undergraduate students completed online questionnaires. Structural equation modelling revealed a series of direct and indirect effects, as evaluated by Sobel's test of indirect effects: (1) FFM personality traits were positively associated with their corresponding behavioural expressions; (2) behavioural expressions of beneficial personality traits (openness to experience, conscientiousness, extraversion, and agreeableness) were positively associated with BPN satisfaction (autonomy, competence, and relatedness), while neuroticism was negatively associated with BPN satisfaction; (3) BPN satisfaction was positively associated with (a) autonomous academic motivation and (b) autonomous friendship motivation; (4) behavioural expressions of personality traits mediated the relationships between their corresponding trait and BPN satisfaction; (5) BPN satisfaction mediated the relationships between behavioural expressions of personality traits and (a) autonomous academic, and (b) friendship motivation and (6) behavioural expressions of personality traits and BPN satisfaction acted as sequential mediators of the associations between personality traits and (a) autonomous academic, and (b) friendship motivation. The sequential action of behavioural expressions of traits and BPN satisfaction as processes that explain the relationship between FFM personality dimensions and autonomous motivation is a novel idea that was put to a successful empirical test herein. Taken together, this research contributes to further our understanding of the intricacies involved in the joint study of the FFM model of personality traits and motivation as conceived by SDT.

Published Article / The relationship between the big five personality traits, Extraversion, Agreeableness Neuroticism, Conscientiousness and Openness to Experience and deep and surface approaches to learning forms the basis of this article. The findings of a research study in this milieu will be presented to prove that earlier studies in this field have been upheld, but that an important deviation has occurred on certain levels of personality. A students way of learning implies the type of learning that is taking place. Ultimately we as lecturers want to encourage deep learning as this stimulates retention of information, important in production of students that are ready for employment.

The general aim of this study was to investigate the relationship between personality traits and team culture, establish whether this relationship changed over time and determine if there were significant differences between the research groups in their personalities and team cultures from a before to an after assessment. The study was conducted on a sample from the South African Police Services and assessments utilising the Basic Traits Inventory (BTI) and the Team Emotional and Social Intelligence survey (TESI) were analysed at the onset and completion of the participants' training. The results indicated a slight relationship between personality and team culture and significant differences were detected from the before to after phases of the study. The findings of the study contribute to an understanding of personality as amenable to a specific occupational setting and of team culture as a more stable variable, which is established early in the team‟s development. / Industrial and Organisational Psychology / M.A. (Industrial and Organisational Psychology)

Inom ramarna för Femfaktormodellen var det övergripande syftet med föreliggande studie att undersöka relationen mellan personlighet och val av utbildning respektive akademisk prestation på den valda utbildningen i ett svenskt stickprov. Vidare undersöktes om Hollands (1997) teori, som utvecklades för snart 20 år sedan i USA, kan vara av betydelse i dagens Sverige. Totalt deltog 177 studenter som vid tidspunkten för datainsamlingen läste program inom humaniora (N = 121) eller ekonomi (N = 56) vid olika svenska universitet. Dessa fyllde i en webbenkät innehållande IPIP-NEO-PI testet (Goldberg, 1999) samt frågor om utbildning, prestation och yrkesintressen enligt RIASEC – modellen (Holland, 1997). Multivariata kovariansanalyser visade att det finns skillnader i personlighet mellan humaniorastudenter och ekonomistudenter som dessutom verkar inte bero på socialisationsprocessen. Separata korrelationsanalyser för de två grupperna visade på skillnader i samband mellan personlighet och prestation beroende på utbildning. Multipla linjära regressionsanalyser visade att det inte är samma personlighetsfaktorer som predicerar prestation då endast humaniorastudenterna undersöktes och då hela urvalet undersöktes vilket kan vara ett tecken på att olika personlighetsfaktorer predicerar prestation i olika utbildningar. Slutligen visade resultatet på skillnader i utbildningsmiljöer mellan humaniora och ekonomi utifrån RIASEC modellen. För gruppen humaniora, men inte för ekonomi, visade resultatet också på att ”fit” mellan individens profil och typ av utbildningsmiljö ledde till högre prestation. Dessa resultat diskuteras i relation till tidigare forskning inom området. I ett bredare perspektiv diskuteras också innebörden av dessa resultat både för praktiken samt vilka aspekter framtida studier bör ta hänsyn till. / Within the framework of the Big Five factor model, the aim of the present study was to investigate the relationship between personality and choice of college major as well as academic performance in a Swedish sample. A secondary aim was to test whether Hollands (1997) vocational choice theory, which was developed for almost 20 years ago in the United States, could be meaningful for Sweden in present-days. A total of 177 students enrolled in college majors within Humanities (N = 121) and Economics (N = 56) from several Swedish universities used a web-based survey to complete the IPIP-NEO-PI inventory (Goldberg, 1999) and to answer questions about their studies, their academic performance and vocational interests according to the RIASEC model (Holland, 1997). Multivariate covariance analyses showed that there were personality differences between humanities students and economics students that seem to pre-exist rather than to be a consequence of a socialization process. Correlation analyses, separate for the two groups, showed different associations of personality factors with performance across groups. Multiple linear regression analyses showed that the personality factors that predict performance were different when only data from humanities students was analysed and when data from the whole sample was analysed which can be interpreted as if the personality factors that predict performance are different across majors. Finally, results showed that there are differences between educational environments of humanities and economics according to the RIASC model. For humanities students, but nor for economics students, the results also showed that “fit” between the individuals profiles and the profile of the environment leads to higher performance. These results are discussed in relation to previous research in the field. From a wider perspective the implications for practice of these results are discussed as well as insights about aspects needed to be considered in future research.

Personlighet är per definition relativt stabila mönster av tankar, känslor och beteenden men det finns även klara belägg för att personlighet kan ändras under hela livsloppet. Exakt hur stabil personligheten är och vilka förändringar som sker hos äldre individer är däremot inte klarlagt. Mognadsprincipen säger att förändring i personlighetsdrag med ökad ålder speglar en funktionell mognad. Nyligen har det föreslagits att sådan mognad i personlighet hos de äldsta individerna skiljer sig från den förändring som sker hos unga vuxna och i medelåldern. Den föreliggande uppsatsen hade två syften. Det första var att undersöka rangordningsstabiliteten i personlighet hos äldre och det andra var att undersöka medelvärdesförändring i personlighetsdrag hos äldre utifrån mognadsprincipen. En longitudinell design användes i ett material av 341 individer mellan åldrarna 60–78 år vid baslinjemätning, över en tidsperiod av 12 år. Personlighet mättes med hjälp av femfaktormodellen (The Big Five). Resultaten visade att: (1) rangordningsstabiliteten var moderat till hög i alla fem personlighetsdrag, (2) Conscientiousness och Extraversion minskade för hela gruppen medan Agreeableness och Openness endast minskade för de yngre deltagarna, (3) Neuroticism visade en icke-signifikant trend av att öka hos de äldsta individerna. Uppsatsens resultat ger stöd för att personlighet är relativt stabil även bland äldre. De förändringar i personlighet som sker verkar skilja sig från trenderna som tidigare påvisats hos unga vuxna och i medelåldern och därmed spegla en annorlunda mognad. / Personality is by definition relatively stable patterns of thoughts, feelings and behaviour but there is also clear evidence that personality can change during the entire life span. Exactly how stable personality is and what kind of changes occur in the elderly, however, is not clear. The maturity principle states that change in personality traits with increased age reflects a functional maturity. Recently it has been proposed that such maturation of personality among the oldest individuals is different from the changes that happen in young adults and in middle age. The current study had two purposes. The first was to examine the rank-order stability of personality in the elderly and the second was to examine mean level change in personality based on the maturity principle. A longitudinal design was used in a sample of 341 individuals between the ages of 60-78 at baseline, over a time period of 12 years. Personality was measured using the five-factor model (The Big Five). The results showed that: (1) the rank-order stability was moderate to high in all five personality traits, (2) Conscientiousness and Extraversion decreased in the entire sample while Agreeableness and Openness decreased only in the younger participants, (3) Neuroticism showed a non-significant trend of increasing in the oldest participants. The results of the thesis support the notion that personality is relatively stable even among the elderly. The changes in personality that do occur seem to deviate from the trends that have been established in young adulthood and middle age and thereby reflect a different maturation.

Det finns individuella skillnader i hur vi påverkas av stress och ett sätt att identifiera skillnaderna är att undersöka hur personlighetsdrag predicerar upplevd stress. Detta kan tillämpas vid rekrytering till yrken med särskilda krav på stresstålighet. Lazarus transaktionsmodell är ledande inom stressforskning och inom personlighetsteorier representerar femfaktormodellens (FFM) neuroticism, extraversion, öppenhet, samstämmighet och samvetsgrannhet de grundläggande personlighetsdragen. Enligt tidigare forskning utgör neuroticism en särskild sårbarhet för stress. Tre hypoteser prövades och undersökningens syftet var att predicera hur personligheten påverkar benägenheten att uppleva stress utifrån FFM, på dimensions- och facettnivå, samt att undersöka skillnader i upplevd stress beroende på kön. Etthundratolv studenter svarade på en enkät innehållande NEO-PI-R som mäter personlighetsdimensionerna samt Perceived Stress Scale (PSS) som mäter upplevd stress. Korrelationsanalyser, t-test och hierarkiska multipla regressioner gjordes. Hypoteserna om neuroticism och stress får stöd i resultatet men inte hypotesen om kön och stress. Oväntade resultat beträffande andra personlighetsdimensioner framkommer och möjliga orsaker till detta diskuteras.

In this thesis we use nonstandard methods for the valuation of derivatives on electricity. We model the dynamics of electricity spot price as mean reverting processes on the hyperfinite binomial tree and by switching to the risk-neutral world we derive analytical formulas for the price of forward contracts. Both of our models are fitted to the German electricity market and forward price predictions are compared with forward products traded on the exchange. We conclude that both the Ornstein-Uhlenbeck and the Schwartz one factor model fit long-term forward contracts well while our prediction results for short-term forward prod- ucts are not conclusive due to low liquidity and alternative approaches might be suitable. 1

De manière générale, la qualité d’un circuit de distribution peut-elle influencer le capital d’une marque ?C’est la principale question que nous traitons dans cette recherche. De nombreuses recherches ont étépubliées sur les déterminants du capital marque. Cependant, peu de choses ont été dites sur le rôle de ladistribution. De plus, une grande partie des recherches ont considéré l’image du point de vente comme unconcept global ou unidimensionnel. Or, la majorité des recherches affirme que l’image du point de vente estun construit multidimensionnel.Le but de cette recherche est d’étudier la relation entre la qualité de la distribution et le capital de la marquequi y est référencée. Nous développons un modèle qui met en relation les dimensions du magasin (l’imageprix, la variété de l’assortiment, la qualité de MDD, la qualité des produits, la qualité de service etl’accessibilité du magasin) et le capital marque, mesuré à l’aide des constantes qui, sont considéréescomme la mesure de l’utilité incrémentale de la marque. Nous utilisons les variables de contrôle telles que lacatégorie de produits. Nous élaborons un modèle factoriel dynamique en utilisant les données de panel sur4500 ménages, 12 magasins appartenant à de chaines différentes en France sur une période de cinq ans etdemi (2004-2009). Les résultats montrent que les effets de l’image du magasin sur le capital marque varientselon l’enseigne, le format de magasin, les catégories de produits, les marques et les caractéristiques desconsommateurs.D’un point de vue théorique, cette recherche permet d’identifier les dimensions les plus pertinentes del’image d’un point de vente ainsi que leurs conditions d’efficacité. D’un point de vue méthodologique, nousutilisons un modèle factoriel dynamique qui n’a pas encore été utilisé sur la mesure du capital marque. D’unpoint de vue managérial, cette recherche permettra aux responsables de marques de mieux apprécierl’influence d’un magasin sur la valeur de leurs marques. / Does a store format quality can generally influence brand equity? This is the main question we address inthis research. Numerous studies have been published on brand equity drivers. However, little has been saidabout the role of distribution. In addition, much research has conceptualized store image as a global or onedimensionalconcept. However, according to the research majority, store image is a multidimensionalconstruct.The purpose of this research is to investigate the relationship between distribution quality and brand equity.We develop a model that connects store image dimensions (price image, assortment variety, private labelquality, product quality, service quality, and location) and brand equity, measured thanks to the interceptswhich are considered as a brand incremental utility measure. The model controls for the variables such asthe product category. We adopt a dynamic factor model using panel data on 4500 households, 12 storesbelonging to different chains in France over a period of five years and a half (2004-2009). The results showthat store image effects on the brand equity depend on the store name, store format, product categories,brands and consumer characteristics.From a theoretical perspective, this research identifies the most relevant store image dimensions as well astheir efficiency conditions. From a methodological point of view, we use a dynamic factor model that has notyet been used on brand equity measurement. From a managerial standpoint, this research may help brandmanagers to better assess the store impact on their brands value.
