In this thesis, probability theory and risk analysis are used to determine the riskof wind energy stocks. Three stocks of wind energy companies and three stocksof technology companies are gathered and risks are compared. Three difffferent riskmeasures: variance, value at risk, and conditional value at risk are used in this thesis.Conclusions which has been drawn, are that wind energy company stock risks arenot signifificantly lower than the stocks of other companies. Furthermore, optimalportfolios should include short positions of one or two of the energy companies forthe studied time period and under the difffferent risk measures.

Even though playing and playfulness can make us feel happy and joyful, for some adults, it might not feel comfortable to be playful at work, especially if it is not perceived as contributing to productivity. Evidence exists, however, regarding positive outcomes of playfulness in the workplace including openness to new ideas and psychological benefits such as divergent thinking, emotional regulation, strengthening of relationships, enhancement of positive communication skills, and providing resources for dealing with stress (Csikszentmihalyi, 2014; Van Vleet & Feeney, 2015b; West, Hoff, & Carlsson, 2016, 2017). Research on playfulness in the workplace is quite limited and this study was conducted to shed light on this behaviour trait in the context of work. Both interpretive (van Manen, 2014, 2016) and post-intentional (Vagle, 2018) phenomenological analytical frameworks were applied to explore the research question: What is the lived experience of playfulness in the workplace? Through semi-structured interviews eight participants, identified as being particularly playful at work and representing a range of professions, discussed the feelings and attitudes of playfulness at work. During interviews participants described attributes of playfulness as feeling alive, fun, goofy, silly, being light-hearted, and happy. Other playfulness attributes were discussed such as an ecstatic experience, spirit lifting, as a planned strategy for building relationships, a method of welcoming new solutions, and a strategy for overcoming difficult tasks. Data was initially classified into categories and clusters of meanings and these summaries were further consolidated into codes and subcodes. Subsequently, the codes and sub-codes were considered as being continuously interconnected and related, always moving with no clear aspect or reduction to a singular theme or essence. Testimonial evidence emerged that revealed the complexity of this phenomenon and that creating a playful environment at work is not as easy as saying, “Let’s have fun!” Playfulness at work was shown to have interrelated components that are flexible and continuously being produced. The behaviour trait of playfulness in the workplace environment is a unique and complex reality and is relatively unexplored. This study contributes to the ongoing discussion regarding the complex nature of this phenomenon and offers a recognition of the challenges of creating a playful climate at work. By adding to the conversation about possible processes for including playfulness in the work environment, this project illustrates that developing a playful climate at work involves intersecting components and an awareness and consideration of these interrelationships. This exploratory study highlights that there is no precise technique to promote playfulness at work, but that it is a complex and continuously shifting phenomenon potentially generating positive workplace outcomes. / Graduate

Yes / In a large-scale survey, 6,641 respondents provided descriptions of their first memory and their age when they encoded that memory, and they completed various memory judgments and ratings. In good agreement with many other studies, where mean age at encoding of earliest memories is usually found to fall somewhere in the first half of the 3rd year of life, the mean age at encoding here was 3.2 years. The established view is that the distribution around mean age at encoding is truncated, with very few or no memories dating to the preverbal period, that is, below about 2 years of age. However, we found that 2,487 first memories (nearly 40% of the entire sample) dated to an age at encoding of 2 years and younger, with 893 dating to 1 year and younger. We discuss how such improbable, fictional first memories could have arisen and contrast them with more probable first memories, those with an age at encoding of 3 years and older.

Through quantitative analysis and inferring a possible relationship between experience of inclusion and happiness at work, this study was designed to answer the following research problem: What is the relationship between experience of inclusion and happiness at work? The general objective was to examine the relationship between experience of inclusion and happiness at work. The specific objectives were analyze if the experience of inclusion has greater impact on eudemonic aspects of happiness than on hedonic aspects, and analyze if the experience of inclusion and happiness at work differ by sex, race/color, age, religion, sexual orientation, hierarchical level, salary range and time in the working group. To achieve the proposed objectives, two questionnaires were used: the Scale of Experience of Inclusion and the Scale of Well-Being at Work. For research purposes, two samples were collected, and by descriptive statistics, linear regression and analysis of variance, the results were achieved. There was a moderate correlation between experience of inclusion and the factors of positive affect and realization/expressiveness, and moderate negative correlation between experience of inclusion and the negative affect. Moreover, the importance of individual and environmental characteristics for individuals fell more included and happier at work was observed. This study sought to contribute to the advancement of the concept of inclusion, in that it sought to clarify the role of the variable happiness at work in the theoretical model of the experience of inclusion. It also enabled contribute to the importance of promoting inclusion in the workplace so that there is happiness, since the latter concept, according some studies, appear to be antecedent of the performance and effectiveness in organizations. / Os temas felicidade e inclusão tem se tornado extremamente preciosos em uma sociedade heterogênea como o Brasil. Por meio de análises quantitativas e inferindo uma possível relação entre experiência de inclusão e a felicidade no trabalho, este estudo propôs-se a responder o seguinte problema de pesquisa: Qual é a relação existente entre Experiência de Inclusão e Felicidade no Trabalho? Teve por objetivo geral analisar a relação entre Experiência de Inclusão e Felicidade no Trabalho. Apresentou, por objetivos específicos, analisar se a experiência de inclusão tem maior impacto sobre os aspectos eudaimônicos da felicidade do que sobre os aspectos hedônicos, e analisar se a experiência de inclusão e felicidade no trabalho diferem por sexo, raça/cor, idade, religião, orientação sexual, nível hierárquico, faixa salarial e tempo no grupo de trabalho. Para alcançar os objetivos propostos, foram utilizados dois questionários: a Escala de Experiência de Inclusão e a Escala de Bem-Estar no Trabalho. Para o estudo realizado, foram utilizadas duas amostras e, por meio de estatística descritiva, regressão linear simples e análises de variância, os resultados foram alcançados. Houve correlação positiva moderada entre experiência de inclusão e os fatores afeto positivo e realização/expressividade, e correlação negativa moderada entre experiência de inclusão e afeto negativo. Além disso, foi observada a importância de características individuais e ambientais para os indivíduos sentirem-se mais incluídos e serem mais felizes no ambiente de trabalho. Este estudo procurou contribuir para o avanço do conceito de inclusão, na medida em que procurou explicitar o papel da variável felicidade no trabalho no modelo teórico da experiência de inclusão. Além disso, permitiu contribuir na identificação da importância de promoção de inclusão no ambiente de trabalho para que haja felicidade, uma vez que este último conceito, segundo alguns estudos, parece ser antecedente ao desempenho e efetividade nas organizações.

Missing data is one of the challenges we are facing today in modeling valid statistical models. It reduces the representativeness of the data samples. Hence, population estimates, and model parameters estimated from such data are likely to be biased. However, the missing data problem is an area under study, and alternative better statistical procedures have been presented to mitigate its shortcomings. In this paper, we review causes of missing data, and various methods of handling missing data. Our main focus is evaluating various multiple imputation (MI) methods from the multiple imputation of chained equation (MICE) package in the statistical software R. We assess how these MI methods perform with different percentages of missing data. A multiple regression model was fit on the imputed data sets and the complete data set. Statistical comparisons of the regression coefficients are made between the models using the imputed data and the complete data.
