Malgré des études prolifiques sur le bien-être et la détresse psychologique, peu d'études ont testé la relation entre ces domaines de la santé mentale. De plus, il y a peu de modèles de la santé mentale qui ont été validés auprès des personnes âgées. II est essentiel de comprendre la notion de santé mentale des personnes agées étant donné le nombre important que represents cette population. Obiectifs : L'objectif de cette étude était de tester un modèle de mesure de la santé mentale chez les Canadiennes et Canadiens agés. Une validation de construit a été realisée pour les échelles de mesures du bien-être et la détresse psychologique et l'hypothèse d'indépendance des deux dimensions a été examinée. Le modèle a été testé selon le sexe et l'âge. Méthodoloqie : Les données proviennent de L'Enquête sur la santé dans les collectivités canadiennes - Cycle 1.2 - Santé mentale et Bien-être de Statistique Canada (2002). Cette étude épidemiologique transversale a été realisée auprès de 37 000 canadiens vivant dans la communauté dont 8 000 personnes de 65 ans et plus. Les échelles de mesures incluent l'Echelle de mesure des manifestations de bien-être psychologique de Masse et al. et le K10, une mesure de détresse psychologique developpée par Kessler et al. Les modèles d'équations structurales ont été testés à l'aide de la version 8.71 de LISREL. Résultats : Le modèle 2-facteur était valide pour les hommes et les femmes ages de 55 - 74 et 75 et plus. Ses résultats sont en accord avec la littérature. L'échele du bien être besoin plus d'études de validation. Des échantillons plus grands des personnes âgées ont nécessaires pour valider l'étude étant donne les méthodes utilités.

BACKGROUND:Researchers are finding limitations of currently available disease-focused questionnaire tools for outcome studies in complementary and alternative medicine/integrative medicine (CAM/IM).METHODS:Three substudies investigated the new one-item visual analogue Arizona Integrative Outcomes Scale (AIOS), which assesses self-rated global sense of spiritual, social, mental, emotional, and physical well-being over the past 24 hours and the past month. The first study tested the scale's ability to discriminate unhealthy individuals (n = 50) from healthy individuals (n = 50) in a rehabilitation outpatient clinic sample. The second study examined the concurrent validity of the AIOS by comparing ratings of global well-being to degree of psychological distress as measured by the Brief Symptom Inventory (BSI) in undergraduate college students (N = 458). The third study evaluated the relationships between the AIOS and positively- and negatively-valenced tools (Positive and Negative Affect Scale and the Positive States of Mind Scale) in a different sample of undergraduate students (N = 62).RESULTS:Substudy (i) Rehabilitation patients scored significantly lower than the healthy controls on both forms of the AIOS and a current global health rating. The AIOS 24-hours correlated moderately and significantly with global health (patients r = 0.50 / controls r = 0.45). AIOS 1-month correlations with global health were stronger within the controls (patients r = 0.36 / controls r = 0.50). Controls (r = 0.64) had a higher correlation between the AIOS 24-hour and 1-month forms than did the patients (r = 0.33), which is consistent with the presumptive improvement in the patients' condition over the previous 30 days in rehabilitation. Substudy (ii) In undergraduate students, AIOS scores were inversely related to distress ratings, as measured by the global severity index on the BSI (rAIOS24h = -0.42, rAIOS1month = -0.40). Substudy (iii) AIOS scores were significantly correlated with positive affect (rAIOS24h = 0.56, rAIOS1month = 0.57) and positive states of mind (rAIOS24h = 0.42, rAIOS1month = 0.45), and inversely correlated with negative affect (rAIOS24h = -0.41, rAIOS1month = -0.59).CONCLUSIONS:The AIOS is able to distinguish relatively sicker from relatively healthier individuals / and correlates in expected directions with a measure of distress and indicators of positive and negative affect and positive states of mind. The AIOS offers a tool for CAM/IM research that extends beyond a disease emphasis.

Borehole imaging is one of the fastest and most precise methods for collecting subsurface data that provides high resolution information on layering, texture and dips, permitting a core-like description of the subsurface. Although the range of information recoverable from this technology is widely acknowledged, image logs are still used in a strictly qualitative manner. Interpreting image logs manually is cumbersome, time consuming and is subjective based on the experience of the interpreter. This thesis outlines new methods that automate image log interpretation and extract subsurface lithofacies information in a quantitative manner. We developed two methodologies based on advanced image analysis techniques successfully employed in remote sensing and medical imaging. The first one is a pixelbased pattern recognition technique applying textural analysis to quantify image textural properties. These properties together with standard logs and core-derived lithofacies information are used to train a back propagation Neural Network. In principle the trained and tested Neural Network is applicable for automated borehole image interpretation from similar geological settings. However, this pixel-based approach fails to make use explicitly of the spatial characteristics of a high resolution image. TAT second methodology is introduced which groups identical neighbouring pixels into objects. The resultant spectrally and spatially consistent objects are then related to geologically meaningful groups such as lithofacies by employing fuzzy classifiers. This method showed better results and is applied to outcrop photos, core photos and image logs, including a ‘difficult’ data set from a deviated well. The latter image log did not distinguish some of the conductive and resistive regions, as observed from standard logs and core photos. This is overcome by marking bed boundaries using standard logs. Bed orientations were estimated using an automated sinusoid fitting algorithm within a formal uncertainty framework in order to distinguish dipping beds and horizontal stratification. Integration of these derived logs in the methodology yields a complete automated lithofacies identification, even from the difficult dataset. The results were validated through the interpretation of cored intervals by a geologist. This is a supervised classification method which incorporates the expertise of one or several geologists, and hence includes human logic, reasoning, and current knowledge of the field heterogeneity. By including multiple geologists in the training, the results become less dependent on each individual’s subjectivity and prior experience. The method is also easily adaptable to other geological settings. In addition, it is applicable to several kinds of borehole images, for example wireline electrical borehole wall images, core photographs, and logging-while-drilling (LWD) images. Thus, the theme of this dissertation is the development of methodologies which makes image log interpretation simpler, faster, less subjective, and efficient such that it can be applied to large quantities of data.

Normative Male Alexithymia (NMA; Levant 1992) and Gender Role Conflict (GRC; O’Neil, 2008) have emerged in the literature as empirically supported masculinity-based constructs that could be possible predictors of men’s psychological well-being. Moreover, several researchers examined the impact of masculinity in the contexts of men’s romantic relationships. Yet, there exists a paucity of research that investigates the intersection of the GRC, NMA, and men’s friendships, and psychological well-being of men. The purpose of this study was to examine the triadic relationship of GRC, NMA, and men’s friendships with other men; and the impact of this triadic relationship on men’s psychological well-being. The researcher collected survey data from 216 participants who identified as male. Data collection included responses to demographic questionnaires, Normative Male Alexithymia Scale (NMAS; Levant et al., 2006), Gender Role Conflict Scale (GRCS; O'Neil et al, 1986), Network of Relationships Questionnaire- Relationship Qualities Version (NRI-RQV; Buhrmester, 1992; Buhrmester & Furman, 2008), and the scales of Psychological Well-Being (SPWB; Ryff, 1989). Bivariate correlations revealed significant correlations among all four variables. NMAS scores yielded a small positive correlation (Cohen, 1988) with the NRI-RQV discordant scales scores (r = .202, p < .01), and a moderate negative correlation (Cohen, 1988) with the total full scale scores of PWB (r = -.427, p < .01). NRI-RQV discordant had a strong negative correlation (Cohen, 1988) with total scores of PWB (r = -.517, n = 216, p < .01). GRCS had a small negative correlation (Cohen, 1988) with the total scores of PWB full scales (r = -.166, n = 216, p < .05). The moderation analysis indicated that GRC significantly moderated the effect of NMA on men’s PWB scores (∆R² = .073, F (1,212) = 20.795, p < .001). High levels of NMA and friendship discords factored in as the best predictor of men’s PWB, and accounted for the 37% variation in overall PWB scores with an effect size of f² = .60. Clinical implications for mental health counselors are discussed based on the study’s results; limitations of the study and future directions are provided.

This thesis focuses on the concept of Single Well Imaging (SWI) in which a seismic source and receivers are deployed in a borehole to investigate the surrounding geology. The Uniwell project (1997-1999) was the first attempt to develop the SWI method; it used a fluid-coupled downhole source, which unfortunately generated high amplitude guided waves in the borehole which obscured all other useful information. Initial research work detailed in this thesis focused on removing the high amplitude guided waves, known as tube waves. Two-step source signature deconvolution using first the recorded source signature, and then the tube-wave reflected from the bottom of the well, succeeded in compressing the tube wave. The results were not consistent across all receivers, but there is enough correlation to identify a P-wave. Further work concentrates on using a new technique called Empirical Mode Decomposition to separate the tube-wave mode from the data. This identifies three dominant modes and a possible body wave arrival, but the results are ambiguous due to the inability of the decomposition to focus on the narrow bandwidth of interest. The source signature deconvolution technique can also be used to process real-time vertical seismic profiling (VSP) data down-hole, during pauses in drilling, in what is referred to as a Seismic-While-Drilling (SWD) setup. Results show that the technique is versatile and robust, giving 1 ms precision on first-break picking even in very noisy data. I also apply the technique to normal VSP data to improve both the resolution and the signal-to-noise ratio. A major effort in this thesis is to consider the effect of a clamped downhole source to overcome the tube-wave problem, using a magnetostrictive source. Earlier work established that the use of a reaction mass tended to excite resonances in the tool which caused the transducer to break. A new design for the source was developed in cooperation with colleagues which utilises a hydraulic amplifier design and a low power coded waveform driving method exploiting the time-bandwidth product to extract the signal from the noise. My results show that as the run time increases the resolution improves. With a run length of 80s it is possible to resolve the signal transmitted 50 cm through a granite formation. This analysis led to a revised design of the source to improve its efficiency. I have used finite difference modelling, with a variable grid technique, to compare an ideal explosive source with an ideal clamped source. The fluid-coupled source emits high amplitude tube waves which virtually obscure the body wave, whereas the clamped source emits a clearly identifiable P-wave along with lower amplitude tube waves. This clearly illustrates the advantage of an ideal clamped source. To model the source more accurately the idealwavelet is replaced by the respective recorded source signatures, and the data is then processed by cross correlation with the appropriate signature. The results show that the coded waveform approaches the resolution of the ideal wavelet very well, with all major events being visible. However, the fluid-coupled source performs very poorly with only the highest amplitude tube-wave visible. This work illustrates that by replacing a fluid-coupled source by a clamped source driven by a coded waveform, and by processing the data using cross correlation or signature deconvolution, it is possible to minimise or eliminate tube-wave noise from a SWI survey. It is hoped that the results outlined here will provide the basis for a new SWI method than can be used to prolong the supply of North Sea oil.

The aim of the present study was to further understand psychological well-being (PWB) and future-directed thinking in individuals with a diagnosis of Borderline Personality Disorder (BPD). A cross-sectional mixed design was used with 24 individuals with a diagnosis of BPD and 24 community participants (Controls). Participants were measured on PWB and a measure of future-directed thinking. Future-thoughts provided by participants were also content analysed, and it was hypothesised the BPD Group would have particularly marked deficits within interpersonal future thoughts. Consistent with previous findings (MacLeod et al., 2004), BPD participants had fewer positive future-directed thoughts compared to Controls, in the absence of any differences in negative future-directed thoughts. The BPD Group had significantly lower PWB scores on all six of the Ryff Psychological Well-being dimensions. The Control Group generated significantly more positive future-directed thoughts related to Relations with Others and Recreational activities, as well as more thoughts related to Having/Raising Children than the BPD Group. The findings extend the understanding of BPD individuals by profiling their well-being and describing in more detail their future-directed thinking.

Thesis (MA)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: The purpose of this study was to examine the relationship between age and the following subjective well-being (SWB) variables: global life satisfaction (as measured by the Satisfaction With Life Scale [SWLS; Diener, Emmons, Larson, & Griffin, 1985], the temporal (past, present and future) dimensions of life satisfaction (as measured by the Temporal Satisfaction With Life Scale [TSWLS; Pavot, Diener, & Suh, 1998]), gratitude (as measured by the Gratitude Questionnaire-Six Item Form [GQ-6; McCullough, Emmons, & Tsang, 2002]) and health satisfaction (as measured by the Health Satisfaction Question [HSQ; Chatters, 1988; Coyle, Lesnick-Emas, & Kinney, 1994; Gwozdoz & Sousa-Poza, 2009]). The interrelationships between these variables were explored, as well as the relationship between certain sociodemographic variables and global life satisfaction in late adulthood. Two groups of male and female South African participants were used, namely, individuals aged between 24-34 years (early adulthood) and 60-75 years (late adulthood). Differences between the two groups with regard to the SWB variables were investigated by using one-way ANOVAs and t-tests, and the interrelationships between the SWB variables were calculated by means of Pearson correlations, for each group seperately, as well as for the two groups combined. Differences in global life satisfaction between different sociodemographic subgroups within the late adulthood group were analysed using one-way ANOVAs and Bonferroni posthoc comparisons. Results indicated that individuals in late adulthood reported significantly higher levels of life satisfaction than individuals in early adulthood. Similarly, individuals in late adulthood reported significantly higher levels of health satisfaction when compared to their younger counterparts. Regarding the trajectories of life satisfaction based on the subscales of the TSWLS, t-tests revealed that the early adulthood group considered their present and future (expected) life satisfaction to be significantly higher than their past life satisfaction. On the other hand, individuals in late adulthood considered only their present to be significantly higher than their past life satisfaction. Pearson correlations indicated significant relationships between global life satisfaction, the temporal dimensions of life satisfaction, and gratitude for both the early and late adulthood groups, as well as for both groups combined. Additionally, gratitude correlated significantly with health satisfaction and future life satisfaction for the early adulthood, but not for the late adulthood group. Neither gender, length of retirement or length of widowhood were significantly related to global life satisfaction, although married individuals reported significantly higher global life satisfaction than those who were not married. The results of the study suggest that there are significant differences between South African early and late adults with regard to some SWB variables and their interrelationships. The implications of these findings were discussed. / AFRIKAANSE OPSOMMING: Die doel van hierdie studie was om die verband tussen ouderdom en die volgende subjektiewe welsyn (SWS) veranderlikes te ondersoek: globale lewensbevrediging (soos gemeet met die Satisfaction With Life Scale [SWLS; Diener, Emmons, Larson, & Griffin, 1985], die temporale (verlede, hede en toekoms) dimensies van lewensbevredigings (soos gemeet met die Temporal Satisfaction With Life Scale [TSWLS; Pavot, Diener, & Suh, 1998]), dankbaarheid (soos gemeet met die Gratitude Questionnaire-Six Item Form [GQ-6; McCullough, Emmons, & Tsang, 2002]) en gesondheidsbevrediging (soos gemeet met die Health Satisfaction Question [HSQ; Chatters, 1988; Coyle, Lesnick-Emas, & Kinney, 1994; Gwozdoz & Sousa-Poza, 2009]). The interverbande tussen hierdie verandelikes is ondersoek, sowel as die verband tussen sekere sosiodemografiese veranderlikes en globale lewensbevrediging in laat-volwassenheid. Twee groepe manlike en vroulike Suid-Afrikaanse deelnemers is gebruik, naamlik individue tussen die ouderdomme van 24-34 jaar (vroeë volwassenheid) en 60-75 years (laat volwassenheid). Verskille tussen die twee groepe wat betref die SWS veranderlikes is ondersoek met eenkantige variansie-analises en t-toetse, en die interverbande tussen die SWS veranderlikes is bereken met behulp van Pearson-korrelasies, vir elke groep afsonderlik, sowel as vir die twee groepe gekombineer. Verskille in globale lewensbevrediging tussen sosiodemografies-verskillende subgroepe binne die laat-volwassenheidgroep is ondersoek met behulp van eenkantige variansie-analises en Bonferroni opvolg-vergelykings. Resultate het aangetoon dat individue in laat-volwassenheid beduidend hoër vlakke van lewensbevrediging gerapporteer het as individue in vroeë volwassenheid. Individue in laat-volwassenheid het ook beduidend hoër vlakke van gesondheidsbevrediging in vergelyking met die jonger groep getoon. Wat betref die trajektorieë van lewensbevrediging gebaseer op die subskale van die TSWLS, het t-toetse aangetoon dat die vroeë volwassenheidgroep hul huidige en toekomstige (verwagte) lewensbevrediging as beduidend hoër as hul verlede-lewensbevrediging beoordeel het. Hierteenoor het individue in laat-volwassenheid slegs hul huidige lewensbevrediging as beduidend hoër as hul verlede-lewensbevrediging beoordeel. Pearson-korrelasies het beduidende verbande aangetoon tussen globale lewensbevrediging, die temporale dimensies van lewensbevrediging, en dankbaarheid vir beide die vroeë - en laat volwassenheid-groepe, sowel as vir beide groepe gekombineer. Verder het dankbaarheid beduidend gekorreleer met gesondheidsbevrediging en toekomstige lewensbevrediging vir die vroeë volwassenheidgroep, maar nie vir die laat- volwassenheidgroep nie. Nie geslag, tydperk van aftrede of tydperk van weduweeskap/ wewenaarskap het beduidende verbande met globale lewensbevrediging getoon nie, alhoewel getroude individue beduidend hoër globale lewensbevrediging as dié wat nie getroud was nie, gerapporteer het. Die resultate van die studie suggereer dat daar beduidende verskille tussen Suid-Afrikaanse vroeë en laat volwassenes bestaan wat betref sekere SWS veranderlikes en hul interverbande. Die implikasies van hierdie bevindings is bespreek.

A critical issue in the development of gas condensate reservoirs is accurate prediction of well deliverability. In this investigation a procedure has been developed for accurate prediction of well production rates using semi-empirical approach. The use of state of the art fine grid numerical simulation is time consuming and computationally demanding, therefore not suitable for real time rapid production management decisions required on site. Development of accurate fit-for-purpose correlations for fluid property prediction below the saturation pressure was a major consideration to properly allow for retrograde condensation, complications of multiphase flow and mobility issues. Previous works are limited to use of experimentally measured pressure, volume, temperature (PVT) property data, together with static relative permeability correlations for simulation of well deliverability. To overcome the above limitations appropriate fluid property correlations required for prediction of well deliverability and dynamic three phase relative permeability correlation have been developed to enable forecasting of these properties at all the desired reservoir conditions The developed correlations include; condensate hybrid compressibility factor, viscosity, density, compositional pseudo-pressure, and dynamic three phase relative permeability. The study made use of published data bases of experimentally measured gas condensate PVT properties and three phase relative permeability data. The developed correlations have been implemented in both vertical and horizontal well models and parametric studies have been performed to determine the critical parameters that control productivity in gas condensate reservoirs, using specific case studies. The improved correlations showed superior performance over existing correlations on validation. The investigation has built on relevant literature to present an approach that modifies the black oil model for accurate well deliverability prediction for condensate reservoirs at conditions normally ignored by the conventional approach. The original contribution to knowledge and practice includes (i) the improved property correlations equations, (4.44, 4.47, 4.66, 4.69, 4.75, 5.21) and (ii) extension of gas rate equations, for condensate rate prediction in both vertical and horizontal wells. Standard industry software, the Eclipse compositional model, E-300 has been used to validate the procedure. The results show higher well performance compared with the industry standard. The new procedure is able to model well deliverability with limited PVT and rock property data which is not possible with most available methods. It also makes possible evaluation of various enhanced hydrocarbon recovery techniques and optimisation of gas condensate recovery.

This thesis is presented as a collection of four studies in which the associations between athlete attachment styles, perceptions of basic psychological needs, and experiences of well/ill-being are examined. The first study of this thesis examined the mediating role of basic psychological need satisfaction, within the coach and parent relational contexts, in the associations between athletes (N = 430) global attachment styles and their experiences of well-being. Results demonstrated that satisfaction of the athletes basic psychological needs did mediate the associations between attachment styles and well-being. Study 2 examined whether mean differences and changes in athletes (N = 110) attachment style predicted psychological need satisfaction, within two relational contexts (coach and parent), and well-being, and whether mean differences and changes in need satisfaction within the relational contexts predicted well-being. Findings from the study provide further support for the role of attachment in need satisfaction and well-being within sport psychology, as well as highlighting important within- and between-person effects. Study 3 aimed to examine the possible social mechanisms that affect insecure athletes (N = 215) perceptions of basic need satisfaction. The social factors investigated as possible mediators were social support, interpersonal conflict, autonomy supportive behaviours, and controlling behaviours, each examined within both the coach and parent relational contexts. The findings of Study 3 highlighted that social factors have an important role in explaining the associations between athletes insecure attachment styles and their perceptions of basic psychological need satisfaction within two important relationships. The final study presented in this thesis aimed to focus on how thwarting of athletes basic psychological needs impacted upon athletes experiences of both well- and ill-being. Study 4 also measured athletes (N = 241) attachment styles to the coach specifically. Findings revealed that when athletes perceptions of their basic psychological needs were actively thwarted, within both aforementioned contexts, athletes insecure attachment to the coach impacted upon experiences of well- and ill-being. Overall, the findings of the current research have supplied new knowledge and understanding concerning athletes psychological functioning through the employment of established theoretical frameworks.

Using cross-cultural and cultural perspectives, this thesis investigated ideals of parenting and the relations between parenting mismatches and youth adjustment in a sample of adolescents from Chinese immigrant families and Canadian non-immigrant families. Asian traditional parenting techniques have been linked to both positive and negative outcomes in Asian immigrant youth. This study sought to clarify these mixed findings by focusing on adolescent interpretations of parenting, specifically their opinions of how parents should behave, which is referred to as parenting ideals. Parental behaviours of warmth, reasoning, monitoring, and harsh discipline were investigated. Results indicated that adolescents from Chinese immigrant families and Canadian adolescents desired similar levels of these parenting behaviours from their fathers and mothers, with the exception of harsh discipline behaviours. Amongst Chinese adolescents, some findings supported the hypothesis that cultural orientation is related to parenting ideals. Parenting mismatches, or discrepancies between actual and ideal parenting, were hypothesized to be related to more depressive symptoms and lower self-esteem. Findings supported this hypothesis in the dimensions of parental warmth and monitoring, but not reasoning. Low endorsement of perceptions, ideals, and mismatches in harsh discipline precluded strong conclusions about this parenting dimension. Directions for future research and implications for parent education and clinical settings were discussed. / Graduate / 0621 / vivienso@uvic.ca
