Ce travail de thèse s'intéresse au problème de l'optimisation globale d'une fonction coûteuse dans un cadre bayésien. Nous disons qu'une fonction est coûteuse lorsque son évaluation nécessite l'utilisation de ressources importantes (simulations numériques très longues, notamment). Dans ce contexte, il est important d'utiliser des algorithmes d'optimisation utilisant un faible nombre d'évaluations de cette dernière. Nous considérons ici une approche bayésienne consistant à affecter à la fonction à optimiser un a priori sous la forme d'un processus aléatoire gaussien, ce qui permet ensuite de choisir les points d'évaluation de la fonction en maximisant un critère probabiliste indiquant, conditionnellement aux évaluations précédentes, les zones les plus intéressantes du domaine de recherche de l'optimum. Deux difficultés dans le cadre de cette approche peuvent être identifiées : le choix de la valeur des paramètres du processus gaussien et la maximisation efficace du critère. La première difficulté est généralement résolue en substituant aux paramètres l'estimateur du maximum de vraisemblance, ce qui est une méthode peu robuste à laquelle nous préférons une approche dite complètement bayésienne. La contribution de cette thèse est de présenter un nouvel algorithme d'optimisation bayésien, maximisant à chaque étape le critère dit de l'espérance de l'amélioration, et apportant une réponse conjointe aux deux difficultés énoncées à l'aide d'une approche Sequential Monte Carlo. Des résultats numériques, obtenus à partir de cas tests et d'applications industrielles, montrent que les performances de notre algorithme sont bonnes par rapport à celles d'algorithmes concurrents.

Emotions have been noted for their crucial role in survival behaviour relating to resistance to cross-cultural ambiguity. Today's globalised multinational corporations (MNCs) have recognised the importance of developing their diverse workforces' intercultural sensitivity (ICS) – a worldview towards cultural difference – as a means of reducing resistance to cross-cultural ambiguity hence maintaining a professional multicultural work environment. However, no studies have yet been made investigating the role of emotional intelligence (EI) in enhancing intercultural sensitivity and simultaneously regulating emotions produced from resistance to cultural difference. Therefore, this study has explored the role of EI in enhancing ICS aiming at increasing the effectiveness of intercultural training within the context of multinational organisations. A theoretical framework was constructed presenting the idea of EI entry-points into intercultural sensitivity and resistance to difference. Through an inductive research approach, a chosen multinational airline company's flight attendants were targeted with in-depth semi-structured interviews. Grounded theory analysis was applied. The analysis resulted in the development of a grounded emotional-cognitive intercultural adaptation process together with three adaptive cognitive states. These were named: Learn, Understand, and Know. Each cognitive state was noted to be associated with a particular emotional state that causes the interacting individual to shift into the relevant cognitive state. The emotions surprise and curiosity were found to be associated with Learn while empathy was found to be associated with Understand, and finally acceptance was found to be associated with Know. The research results strongly support the proposed EI entry-points within the grounded emotional-cognitive content of the produced intercultural adaptation process. The results address the research aim regarding the role of EI in enhancing ICS. Through the EI entry-points, ICS is indirectly enhanced through the development of intercultural performance as EI mental abilities are proposed which would regulate one's behaviour towards the three grounded emotional-cognitive intercultural adaptation states. The developed model is suggested to contribute to enhancing the effectiveness of intercultural training. The trainee's intercultural performance could be enhanced through directing the emotional-cognitive dynamics, during intercultural interaction, towards the empirically grounded set of emotional-cognitive states. As linking EI and ICS remains an important and under-explored topic, it is hoped that the findings of this study will present a better understanding of the dynamics of emotions within the context of multinational organisations, as well as the role of EI in enhancing ICS, subsequently leading to further research.

Business leaders are increasingly coming to recognise that there is more to business success than technical and cognitive competence. Personnel leadership is proving to be critical for business bottom-line achievements considering that most business outcomes are achieved through human capital. Emotional intelligence can be used to the advantage of organisations by developing an emotional intelligence audit. The objective of this study was to investigate the psychometric properties of the Emotional Intelligence Scale (SEIS) developed by Schutte, Malouff, Hall, Haggerty, Cooper, Golden and Dornheim (1998) for Economic Science students from a higher education institution in the North-West Province, South Africa. The psychometric soundness of the SEIS was tested. The general objective of the research is to standardise a psychometric instrument of emotional intelligence and determine the validity of The Schutte Emotional Intelligence Questionnaire (SEIS) (Schutte, et al., 1998). Specific objectives include the conceptualisation of the importance of a standardised psychometric instrument of emotional intelligence in South Africa; the conceptualisation of the nature and evolvement of emotional intelligence measurements in general; determining the validity and internal consistency of the SEIS; and establishing whether any possible group differences in terms of biographical data exist in emotional intelligence. A valid and reliable measure of emotional intelligence could be valuable in the organisation to identify specific EI needs that could be developed through the implementation of EI development programmes. In this context a standardised psychometric instrument of EI could be of use in organisations during the training and development of employees. A cross-sectional method with an availability sample (N = 341) from Economical Science students from a higher education institution was used. The results supported a six-factor model of emotional intelligence, consisting of Positive Affect, Emotion-Others, Happy Emotions, Emotions-Own, Non-verbal Emotions and Emotional Management. The multi-analysis of variance (MANOVA) was used to determine differences in terms of biographical data. The results indicated significant differences between gender and language groups. African language groups compared with Afrikaans and English language groups experienced higher levels of positive affect. Females compared with males experienced higher levels of understanding of the emotions of other people. Recommendations for future research were made. / Thesis (M.A. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2006.

The research on Emotional Intelligence (EI) has advanced considerably over the past 20 years because of the construct’s scientific and practical relevance. However, in South Africa, a measurement instrument of EI that is valid, reliable, standardised, has a consistent factor structure, in a homogeneous working sample and that can be utilised for research and practical purposes is still elusive. EI plays a fundamental role in the quality of service rendered by nurses (Murphy & Janeke, 2009). According to Ogillska-Bulik (2005) the ability to manage one’s own emotions, while having the ability to identify others' emotions, is very important in the nursing environment. The Schutte Emotional Intelligence Scale (SEIS) has been found as a reliable brief scale for measuring trait EI (Schutte & Malouff, 1998). However, there are different results regarding the factor structure of the S. The first objective of this research study was to conceptualise EI and the factor structure of the SEIS through a literature review. Salovey and Mayer (1990) define EI as a mental ability pertaining to the relationship between emotion and cognition. Other researchers’ definition of EI states that EI is the ability to be conscious of one’s emotions, to evaluate and develop one’s emotions to assist thinking, to comprehend emotions and emotional information, and to manage emotions to sustain emotional and intellectual development in oneself (Bar-On, 2000; Goleman, 1998; Salovey & Mayer 1997). Murphy and Janeke (2009) state it is important that reliable and valid measures of EI must be used in the workplace. Numerous research has been done on the most appropriate, valid and reliable approach for the measurement of EI (Petrides & Furnham, 2000; Van Rooy & Viswesvaran, 2005). The SEIS is the leading brief scale for measuring EI (Petrides & Furnham, 2000). However, there are problems with its factor structures. To summarise: a) Schutte et al. (1998) report a unifactorial structure for the SEIS, b) Austin, Saklofske, Huang, and McKenny (2004) report a three-factor structure. c) Petrides and Furnham (2000); Ciarrochi, Chan, and Bajar (2001); Ciarrochi, Chan, Caputi, and Roberts (2001) and Saklofske, Austin, and Minski (2003) report a four-factor structure. d) Jonker and Vosloo (2009) reported a six-factor structure. The second objective of this study was to investigate the factor structure of the 41-item version of the Schutte Emotional Intelligence Scale within a South African nursing environment by means of a confirmatory factor analysis. A quantitative research design was used in this study. A cross-sectional survey design was used for this study. An availability non-probability sample (N = 290) was taken from hospitals in the Gauteng and North-West Provinces of South Africa. The Schutte Emotional Intelligence Scale was applied as measuring scale. An exploratory factor analysis (principal component analysis) was performed on the data. The data did not fit a unifactor, two-factor or three-factor model based on the model of Austin, Saklofske, Huang, and McKenney (2004). The data fitted the original model of Emotional Intelligence of Mayer and Salovey (1990), best explaining 58.52% of the variance. The results supported a five-factor structure of the Schutte Emotional Intelligence Scale. The five factors were named: Emotion Utilisation; Emotion Management; Emotion Awareness; Emotion Perceiving and Emotion Integration. Recommendations were made for future research. / Thesis (MCom (Industrial Psychology))--North-West University, Potchefstroom Campus, 2013

 Title: Emotional Intelligence in an Entrepreneurial context Background: Emotional Intelligence (EI) has been said to matter twice as much as Intelligent Quotient (IQ) for predicting business success (Goleman, 1998b). This study addresses Emotional Intelligence in previously unexplored context in Sweden: entrepreneurship. Purpose: The purpose of this research is to explain Emotional Intelligence and its possible relationship with the entrepreneur. Hypothesis: Being an entrepreneur is positively related to EQ Method: The study has a deductive research approach where the hypothesis is formed by the theoretical framework of Emotional Intelligence, providing an empirical framework that measures the concept in the entrepreneurial context and outlines linkages among the constructs. The study is conducted among members of the business organization Företagarna in Region Halland, Sweden, by the measurement instrument Emotional Intelligence Scale (EIS). Conclusion: The assumptions derived from a theoretical perspective could be confirmed empirically. Being an entrepreneur is positively related to EQ. Keywords: CEO, EI, EIS, EQ, Emotional Intelligence, Entrepreneurs, Entrepreneurship

A partir de estudos de Avaliação de Ciclo de Vida (ACV), tem-se desenvolvido estratégias de otimização das etapas complexas que essa requer, através da Avaliação de Ciclo de Vida Energético (ACVE). Este trabalho buscou discutir a ACVE nas etapas de pré-uso, uso e manutenção e desconstrução de um projeto típico de habitação térrea para o Distrito Federal no Brasil, de 45,64 m², abordando os sistemas de vedação vertical internos e externos. As vedações abordadas foram parede de concreto moldadas no local, alvenaria estrutural de blocos de concreto, steel frame e convencional. Buscou-se também realizar ensaios com a finalidade de obter a EI para a fase de desconstrução, abordando também a EI dos resíduos. Como resultados, verificou-se que as vedações em alvenaria estrutural apresentaram menor EI total. Em todas as situações, a etapa de desconstrução comportou-se como sendo a de menor EI, representando em média 1% da EI total. A etapa de uso e manutenção teve a maior EI para os sistemas abordados. Já a etapa de pré-uso teve maior EI para dois sistemas, sendo as vedações de painéis de concreto com apenas uma utilização das fôrmas e as vedações em steel frame, o qual apresentou no conjunto das três etapas a maior EI total. A partir da análise dos resíduos das vedações na etapa de desconstrução, encontraram-se resultados de que os resíduos podem representar de 6 (seis)% até 11 (onze)% da EI total. Os estudos mostraram que nas condições específicas da pesquisa, os valores para EI total para as vedações foram de 13,17 GJ/m² até 31,99 GJ/m². ________________________________________________________________________________________________ ABSTRACT / The study of embodied energy (EE) in the research context of sustainability on the construction supply chain has contributed for science and technology in Brazil, but the researches are still incipient. Based on studies on Energy Life Cycle Assessment (Energy LCA), some strategies to optimize the complex phases of Life Cycle Assessment (LCA) have been developed. This work discuss Energy LCA in the pre-use, use as well as demolition phases of a typical project of a social housing of one story of 45,64 m² in Distrito Federal, situated in Brazil. The thesis addresses internal and external walls. They addressed walls were concrete wall molded-in-place, structural masonry of concrete block, steel frame and traditional masonry. Tests were made to obtain the EE in the demolition phase, addressing EE of remnants. As a result, it was possible to verify that the structural masonry wasted less total EE than the others. In every analyzed situation, the demolition phase was the one that wasted less EE, representing 1% of the total EE. The use phase consumed the most part of the EE. The pre-use phase consumed the most part of the EE for concrete wall when it uses just one form and for steel frame which presents the higher spending of total EE throughout the three phases. Based on the analyze of the remnants of the internal and external walls in the demolition stage, the remnants can represent from 6% to 11% of total EE.The studies indicated that the amount of total EE for internal and external walls were from 13,17 GJ/m² to 31,99 GJ/m², at the specific conditions of this research.

The purpose of this study was to identify characteristics pertaining to emotional intelligence (EI) that parents and Foundation Phase teachers may use when supporting learners with autism spectrum disorder (ASD) in an inclusive classroom setting. Teachers are facing various degrees of challenges due to the demands of a range of diverse needs attributable to the influx of learners with disabilities in the school system. Given the increase in the number of children diagnosed with ASD, research indicates that it is likely that teachers will encounter learners with ASD in their classes. Teachers are generally not trained to identify and cope with such a disability, as many requirements of these learners are beyond the services of a general school system. A multiple case study was conducted where the perspectives of a teacher and two parents were gained, in order to understand experiences with children with ASD from the participants' point of view. The primary aim of this study was therefore to provide both parents and teachers with listed characteristics of EI that they could utilise while supporting learners with ASD in households or the educational sphere. Findings illuminated the collective characteristics of learners with ASD, which include intense obsessions with a narrow range of subjects, repetitive routines, central coherence difficulties and problems with social-emotional functioning, communication and executive functioning. These indicators require specific responses from parents and teachers to effectively provide support to these learners. Qualities identified that relate to EI are patience, empathy, problem solving skills, working collaboratively with parents and being proactive. The main recommendation relates to specific training in EI skills, to prepare student teachers in supporting the growing number of learners with ASD in their classes. / Dissertation (MEd)--University of Pretoria, 2017. / Early Childhood Education / MEd / Unrestricted

A method to detect nitrated polycyclic aromatic hydrocarbons (nitro-PAHs) in the air has been developed using gas chromatography with an atmospheric pressure chemical ionisation source, coupled to a triple quadrupole mass spectrometer (GC-APCI-MS/MS). An attempt to create a GC method using negative chemical ionisation (NCI) and a high-resolution mass spectrometer, Orbitrap, (GC-NCI-MS) was made as well without success. Nitro-PAHs are a group of widespread contaminants considered as possible mutagens and carcinogens. They are formed from incomplete combustion of organic matter as well as secondary reactions between PAHs and nitrogen dioxide (NO2) in the air. Three air samples (outdoor, in an air vent and indoor), both particulate and gaseous phase, collected in central Örebro during the spring were extracted and analysed for nitro-PAHs on GC-APCI-MS/MS and for PAHs on GC-MS in EI (electron ionisation) mode. Several studies have reported lower amounts of nitro-PAHs than PAHs in the air, which can be seen in this report as well. The levels of detected nitro-PAHs (1-nitronaphalene and 9-nitroanthracene) and PAHs (naphthalene, anthracene, fluoranthene and pyrene) in the different samples were 10.2-119 pg/m3 and 291-77700 pg/m3, respectively. Neither group of analytes were found in the particulate phase. The highest concentrations of both nitro-PAHs and PAHs were found indoors, suggesting that other sources than emissions from traffic are responsible.
