Consider an under-determined system of nonlinear equations F(x)=0, F:R^m→R^n, where F is continuously differentiable and m > n. This system appears in a variety of applications, including parameter-dependent systems, dynamical systems with periodic solutions, and nonlinear eigenvalue problems. Robust, efficient numerical methods are often required for the solution of this system. Newton's method is an iterative scheme for solving the nonlinear system of equations F(x)=0, F:R^n→R^n. Simple to implement and theoretically sound, it is not, however, often practical in its pure form. Inexact Newton methods and globalized inexact Newton methods are computationally efficient variations of Newton's method commonly used on large-scale problems. Frequently, these variations are more robust than Newton's method. Trust region methods, thought of here as globalized exact Newton methods, are not as computationally efficient in the large-scale case, yet notably more robust than Newton's method in practice. The normal flow method is a generalization of Newton's method for solving the system F:R^m→R^n, m > n. Easy to implement, this method has a simple and useful local convergence theory; however, in its pure form, it is not well suited for solving large-scale problems. This dissertation presents new methods that improve the efficiency and robustness of the normal flow method in the large-scale case. These are developed in direct analogy with inexact-Newton, globalized inexact-Newton, and trust-region methods, with particular consideration of the associated convergence theory. Included are selected problems of interest simulated in MATLAB.

How does the satisfaction (or the lack of satisfaction) of the innate need to have meaningful interpersonal relationships affects behavioural self-regulation? How does having/lacking interpersonal relatedness impact one’s perception of future interpersonal relationships? This doctoral dissertation aimed to answer these two fundamental questions by integrating the views of two complementary theories, need to belong theory (NBT; Baumeister & Leary, 1995) and self-determination theory (SDT; Deci & Ryan, 1985, 2000). Using a series of two laboratory experiments and one longitudinal study, this thesis examined the effects of social exclusion and inclusion on satisfaction of basic psychological needs, self-determined motivation, and self-regulation of behaviours. In Study 1 (N=72), social exclusion and inclusion were manipulated in order to examine their effects on the satisfaction of the three basic psychological needs proposed by SDT, that is the needs for autonomy, competence, and relatedness. Findings from this first experiment revealed that social exclusion decreases satisfaction of the three needs, whereas social inclusion increases satisfaction of these needs when compared to the control condition. Furthermore, significant differences were found between the exclusion condition and the inclusion condition for the reported levels of satisfaction of the needs for competence and relatedness. The effects of social exclusion and inclusion on basic needs satisfaction were further investigated in Study 2 (N=70); also, the second study examined how self-determined motivation and behavioural self-regulation are affected. More specifically, it tested whether participants’ persistence at a laboratory task, as well as their intentions for a future peer interaction (intentions to compete against a peer participant and intentions to collaborate with a peer participant) are influenced by social exclusion and inclusion, through the meditating effects of basic needs satisfaction and self-determined motivation. The results suggested that social exclusion, via the effects of basic needs and motivation decreases peer collaboration, whereas social inclusion was shown to have an opposite effect on peer collaboration. The effect of condition via the mediating effects of basic needs satisfaction and motivation failed to predict persistence at the task and peer competition. Lastly, Study 3 (N=624) assessed naturally occurring social exclusion and inclusion in a population of junior high school students. This third study investigated the independent contributions of SDT and NBT in the prediction of academic motivation and high school dropout. Peer relatedness, perceived needs support from parents, and perceived needs support from teachers were examined as potential predictors of academic motivation and high school dropout. Findings suggested that peer relatedness plays an important role in the prediction of academic motivation, but, that perceived needs support from parents and perceived needs support from teachers are stronger predictors of that outcome. Results from this study also revealed that peer relatedness contributes to the prediction of high school dropout, beyond what can be explained by academic motivation, perceived needs support from parents, and perceived needs support from teachers. However, perceived needs support from parents was shown to be the most essential predictor of high school dropout. In sum, findings from this doctoral dissertation suggested that social exclusion has detrimental effects on one’s motivation and behavioural self-regulation. In contrast, social inclusion fosters social support which promotes satisfaction of the basic psychological needs, self-determined motivation, and successful self-regulation. This doctoral thesis contributed to the application of SDT and NBT by comparing elements of the two complementary frameworks. It also offered an original contribution to research on social exclusion and inclusion by examining their impacts on self-determined motivation, and basic needs satisfaction, as well as testing them in both the laboratory setting and the natural setting.

Ce projet propose une nouvelle approche de la résilience en vue d’assurer le bien-être chez les enseignants. Les raisons qui nous amènent à un tel intérêt sont notamment le stress intense ressenti dans le corps professoral où la tâche est lourde et particulièrement difficile. Sera donc abordé au chapitre premier, le fait que l’environnement de travail, par ses caractéristiques, génère du stress et des effets néfastes. Par la suite, la résilience étant sollicitée pour retenir les travailleurs en poste, nous décrirons son historique, ce qui nous amènera à soulever une problématique d’importance, notamment le fait qu’elle ne soit pas nécessairement accompagnée d’un bien-être salutaire. En contrepartie, un des indicateurs du bien-être est la motivation autodéterminée. Nous détaillerons ces notions et verrons comment elles sont atteintes par les conditions mêmes de travail. Cette mise en contexte nous permettra, en chapitre deuxième, de concevoir la résilience sous un autre jour grâce à la mise en lien avec les motivations autodéterminées. S’y dessineront deux types importants, dans lesquels motivation et bien-être devraient différer sensiblement. Cela pourrait expliquer la raison d’un bien-être mitigé. Nous terminerons ce chapitre par nos hypothèses. Nous aborderons ensuite la vérification de la proposition de types de résilience sous-tendues par la motivation. Au chapitre troisième, la méthodologie décrira l’échantillon de 465 enseignants québécois du primaire et du secondaire, les différents questionnaires de résilience, motivation et bien-être aux fins de l’étude transversale. Le chapitre suivant traitera des résultats des ANOVA , MANOVA et ANOVA factorielles entreprises. Notamment, les différences statistiques de bien-être et de motivation seront détaillées, ainsi que la non interaction entre motivation et résilience. Les effets principaux de résilience à tous les niveaux de motivation seront décrits. Les résultats obtenus nous permettrons une discussion au chapitre cinquième avant de conclure qu’effectivement, des différences sont observables, que la résilience pourrait s’opérer en deux formes durant lesquelles les motivations et le bien-être sont différents. Il sera possible d’envisager la résilience non pas comme une caractéristique personnelle stable ou un résultat statique, mais comme un processus pouvant prendre différentes formes qu’il serait alors possible de promouvoir. En découle également une mise en garde contre le fait de penser qu’il n’est plus nécessaire d’agir auprès des personnes étiquetées de résilientes. Le soutien semble encore nécessaire pour soutenir un processus efficace. / This project proposes a new approach to resilience in order to ensure well-being among teachers. The reasons which lead us to such an interest include the intense stress experienced by teachers in their work due to the heavy and difficult workload. In Chapter 1 we will discuss the work environment and its characteristics, which generate stressors and adverse effects. We then turn to the concept of resilience which is sought for in the effort to retain workers. We describe its history which will lead into the important issue that resilience is not necessarily accompanied by healthy well-being. One indicator of well-being is self-determined motivation. We explore these concepts and see how they are affected by the conditions in the workplace. This background will allow us in Chapter 2 to develop the concept of resilience in a different way by bringing it into relation with self-determined motivation. We will distinguish between two important types of resilience in relation to which motivation and well-being should differ significantly. We will then examine the proposed types of resilience underpinned by motivation. In Chapter 3 we describe the methodology in a sample study of 465 primary and secondary school teachers including the questionnaires on resilience, motivation and well-being used in this transversal study. The following chapter will discuss the results of ANOVA, MANOVA and factorial ANOVA. In particular, statistical differences in well-being and motivation will be detailed as well as the non-interaction between motivation and resilience. Principal effects of resilience for all levels of motivation will be described. The results will show that resilience can occur in two types in which motivation and well being differ. It will be possible to consider resilience not as a static characteristic but as a process which can take different forms which can be promoted. It follows as well that one should not think that resilient people will never be in need of further intervention. Support remains necessary to ensure an efficient process.

Thesis (MScEng (Electrical and Electronic Engineering))--University of Stellenbosch, 2011. / ENGLISH ABSTRACT: This thesis presents a system that is designed to replace the manual process of generating a pronunciation dictionary for use in automatic speech recognition. The proposed system has several stages. The first stage segments the audio into what will be known as the subword units, using a frequency domain method. In the second stage, dynamic time warping is used to determine the similarity between the segments of each possible pair of these acoustic segments. These similarities are used to cluster similar acoustic segments into acoustic clusters. The final stage derives a pronunciation dictionary from the orthography of the training data and corresponding sequence of acoustic clusters. This process begins with an initial mapping between words and their sequence of clusters, established by Viterbi alignment with the orthographic transcription. The dictionary is refined iteratively by pruning redundant mappings, hidden Markov model estimation and Viterbi re-alignment in each iteration. This approach is evaluated experimentally by applying it to two subsets of the TIMIT corpus. It is found that, when test words are repeated often in the training material, the approach leads to a system whose accuracy is almost as good as one trained using the phonetic transcriptions. When test words are not repeated often in the training set, the proposed approach leads to better results than those achieved using the phonetic transcriptions, although the recognition is poor overall in this case. / AFRIKAANSE OPSOMMING: Die doelwit van die tesis is om ’n stelsel te beskryf wat ontwerp is om die handgedrewe proses in die samestelling van ’n woordeboek, vir die gebruik in outomatiese spraakherkenningsstelsels, te vervang. Die voorgestelde stelsel bestaan uit ’n aantal stappe. Die eerste stap is die segmentering van die oudio in sogenaamde sub-woord eenhede deur gebruik te maak van ’n frekwensie gebied tegniek. Met die tweede stap word die dinamiese tydverplasingsalgoritme ingespan om die ooreenkoms tussen die segmente van elkeen van die moontlike pare van die akoestiese segmente bepaal. Die ooreenkomste word dan gebruik om die akoestiese segmente te groepeer in akoestiese groepe. Die laaste stap stel die woordeboek saam deur gebruik te maak van die ortografiese transkripsie van afrigtingsdata en die ooreenstemmende reeks akoestiese groepe. Die finale stap begin met ’n aanvanklike afbeelding vanaf woorde tot hul reeks groep identifiseerders, bewerkstellig deur Viterbi belyning en die ortografiese transkripsie. Die woordeboek word iteratief verfyn deur oortollige afbeeldings te snoei, verskuilde Markov modelle af te rig en deur Viterbi belyning te gebruik in elke iterasie. Die benadering is getoets deur dit eksperimenteel te evalueer op twee subversamelings data vanuit die TIMIT korpus. Daar is bevind dat, wanneer woorde herhaal word in die afrigtingsdata, die stelsel se benadering die akkuraatheid ewenaar van ’n stelsel wat met die fonetiese transkripsie afgerig is. As die woorde nie herhaal word in die afrigtingsdata nie, is die akkuraatheid van die stelsel se benadering beter as wanneer die stelsel afgerig word met die fonetiese transkripsie, alhoewel die akkuraatheid in die algemeen swak is.

Religion was not free to participate in this social phenomenon, despite having set the pace and the meaning of life for centuries. In Brazil a minority religious group, namely evangelicals historically had among its main features membership and participation of the faithful in a church institution. In contemporary times there has been a new phenomenon in this religious field, ie, the existence of evangelicals without bond and participation in a faith community. This paper discusses this process of deinstitutionalization. Looking collaborate to expand the understanding of this phenomenon, reporting a field research with alumni (as) evangelical theology, which despite having been trained to lead evangelical churches have chosen not to belong the same. With this research outline demonstrates the depth of this phenomenon and the narratives of the respondents it was found that spirituality and faith are beyond the institution/church. / Em especial no ocidente, as instituições perdem o seu poder de influência. A religião não ficou isenta de participar deste fenômeno social, apesar de ter ditado o ritmo e o sentido da vida durante muitos séculos. No Brasil um grupo religioso minoritário, a saber, os evangélicos, historicamente tiveram entre as suas principais características a pertença e a participação dos fieis em uma igreja/instituição. Na contemporaneidade tem ocorrido um fenômeno novo neste campo religioso, ou seja, a existência de evangélicos sem vínculo e participação em uma comunidade de fé. Esta dissertação discute este processo de desinstitucionalização. Procurando colaborar para a ampliação da compreensão deste fenômeno, relatando uma pesquisa de campo com ex-alunos(as) de teologia evangélica que, apesar de terem sido treinados para liderar igrejas evangélicas, optaram por não mais pertencer as mesmas. Com este recorte de pesquisa demonstra-se a profundidade deste fenômeno e nas narrativas dos entrevistados constata-se que a espiritualidade e a fé estão para além da instituição/igreja.

Studiens syfte var att undersöka om (a) självbestämmande motivation medierar sambandet mellan behovstillfredsställelse och idrottsrelaterad utbrändhet. Samt om (b) kontrollerad motivation medierar sambandet mellan behovstillfredsställelse och idrottsrelaterad utbrändhet. Föreliggande studie är en kvantitativ tvärsnittsstudie och datainsamling genomfördes via tillgänglighetsurval. Totalt deltog 138 Crossfit deltagare i åldrarna 19 - 58 år (M= 32.19, Sd= 9.02). Baserat på studies syftet skapades två hypoteser som vidare testades i varsin medieringsanalys. Medieringsanalys 1 kunde inte bekräfta hypotesmodell 1 då resultatet påvisar en icke signifikant indirekt effekt mellan behovstillfredsställelse och idrottsrelaterad utbrändhet via självbestämmande motivation. Å andra sidan kunde medieringsanalys 2 bekräfta hypotesmodell 2 eftersom resultatet visar en signifikant indirekt effekt mellan behovstillfredsställelse och idrottsrelaterad utbrändhet via kontrollerad motivation. Resultatet tydliggör förståelsen av att kontrollerad motivation inom Crossfit anses bidrar med lägre grad av behovstillfredsställelse och ökar risken för utveckling av idrottsrelaterad utbrändhet. / The purpose of the study was to investigate if (a) self-determining motivation mediates the correlation between psychological need satisfaction and athletic burnout. Also, if (b) controlled motivation mediates the correlation between psychological need satisfaction and athletic burnout. The current study is a quantitative cross-sectional study. Data was collected by accessibility sampling. There were 138 Crossfit participants who participated in the ages 19 - 58 (M= 32.19, Sd= 9.02). Based on the purpose of the study were two hypotheses created and tested in two separated mediation analysis. Mediation analysis 1 in the study could not accept hypotheses 1, based on the result which indicated no significant indirect effect between psychological need satisfaction and athletic burnout through self- determination motivation. Opposite, mediation analysis 2 could accept hypotheses 2 based on the result which indicated a significant indirect effect between psychological need satisfaction and athletic burnout through controlled motivation. The results illustrate the understanding of controlled motivation in Crossfit because it contributes lower psychological need satisfaction and higher the risk of developing athletic burnout.
