Full textAbstract:
University of Central Florida College of Engineering ThesisCryptosporidium parvum is a common surface water contaminant that can cause illness in human beings. The presence of this etiological agent in groundwater identifies the groundwater as under the direct influence (GWUDI) of surface water. Currently the determination of SWUDI water sources requires an expensive, labor-intensive laboratory procedure call the Microscopic Particulate Analysis (MPA). The results of the MPA provide a risk index that rates the degree of surface water contamination. The objective of this study is to identify other methods of identifying GWUDI of surface waters, such as well characteristics and hydrogeologic factors which may contribute to higher MPA risk indices. In order to determine which public water systems that are GWUDI, a total of sixty-two wells a water treatment systems suspected of bein GWUDI were investigated. The wells sampled were distributed across seven countried in the Central Florida region. Water samples were collected and analyzed at the Department of Health Laboratory in Tampa, Florida using the MPA. The study also investigated the well characteristics and the hydrogeology of the well locations. The results also showed that 13% of the wells sampled were in the high risk range while 29% and 58% of the wells sampled were within the moderate and low risk ranges, respectively. It was also observed that some well characteristics and the hydrogeology of an area generally influence the MPA risk index. The results also suggested that older well tend to have higher risk. Karst regions were observed to be susceptible to a higher risk than sandy areas.

Full textAbstract:
A Work Project, presented as part of the requirements for the Award of a Masters Degree in Economics from the NOVA – School of Business and EconomicsNowadays many social scientists defend the advantages to define a measure of well being able to complement the GDP per capita. This work project proposes a new index of human development: the happiness index. Many studies have been undertaken in order to determine the best measurement of happiness. Happiness is much more than just feeling good, it is also living and doing well. Thus, in order to create a measure of happiness, it is required to evaluate all factors that intervene and, on the other hand, to consider the best practices, combining growth, environmental sustainability and efficiency. The estimation was made based on data for 83 countries, and then applied to 130 countries in the period 1997-2005. Countries with the highest GDP per capita or Human Development Index are not the ones with the higher happiness index.

Full textAbstract:
Motivated by the reservoir engineering concept of the productivity index of a producing oil well in an isolated reservoir, we analyze a time dependent functional, diffusive capacity, on the solutions to initial boundary value problems for a parabolic equation. Sufficient conditions providing for time independent diffusive capacity are given for different boundary conditions. The dependence of the constant diffusive capacity on the type of the boundary condition (Dirichlet, Neumann or third-type boundary condition) is investigated using a known variational principle and confirmed numerically for various geometrical settings. An important comparison between two principal constant values of a diffusive capacity is made, leading to the establishment of criteria when the so-called pseudo-steady-state and boundary-dominated productivity indices of a well significantly differ from each other. The third type boundary condition is shown to model the thin skin effect for the constant wellbore pressure production regime for a damaged well. The questions of stabilization and uniqueness of the time independent values of the diffusive capacity are addressed. The derived formulas are used in numerical study of evaluating the productivity index of a well in a general three-dimensional reservoir for a variety of well configurations.

Full textAbstract:
This study assessed the effect of variables such as life satisfaction, self-rated health, social support and coping styles on subjective well-being. The level of subjective well-being was studied in a sample of Mexican elderly persons from the state of Yucatan in Merida (n = 122) with an age range of 60-93 years. The results in women show that coping styles predicts subjective well-being in negative affects. Moreover, self-perception of health, coping styles, and satisfaction with life are adequate predictors of the cognitive dimension of subjective well-being. Results in men show that satisfaction with life and coping styles predict the cognitive dimension of subjective well-being. Findings point to the importance of exploring psychosocial variables in older adults.El presente estudio evaluó el efecto de las variables satisfacción con la vida, autopercepción de salud, apoyo social y estilos de enfrentamiento sobre el bienestar subjetivo. Se contó con una muestra de 122 adultos mayores mexicanos del Estado de Yucatán, en la ciudad de Mérida con un rango de edad de 60 a 93 años. Los resultados en mujeres muestran que los estilos de enfrentamiento son predictores del bienestar subjetivo en los afectos negativos. En cuanto a la dimensión cognitiva del bienestar subjetivo, la autopercepción de salud, los estilos de enfrentamiento y la satisfacción con la vida fueron predictores adecuados. En hombres, los resultados demuestran que la dimensión cognitiva del bienestar subjetivo fue predicha a partir de la satisfacción con la vida y los estilos de enfrentamiento. Los hallazgos muestran la importancia del profundizar y promover variables psicosociales en los adultos mayores.

Full textAbstract:
The main goal of this study is to develop a brief scale to assess perceived well being in adolescentpopulation. Besides verifying psychometric properties, we identified individual differences between genders, context and age. Participants were adolescent students recruited in three different areas of Argentina (Metropolitan area -Buenos Aires-, Norwest area- Tucuman- and Southwest area Patagonia- ). aged 13 Th. 18. Instruments administered consisted of BIEPS (well being scale) other classics instruments to assess life satisfaction (SWLS and D-T) anda symptom check list (SLC- 90). Results show that classic instruments to assess well being resulted in less reliable instruments to assess perceived life satisfaction considering other theories. Gender, age and context don't seem to affect subjective perception of psychological well being.El objetivo de este estudio es el desarrollo de una escala breve para la evaluación del bienestar psicológico en adolescentes, la revisión de sus características psicométricas. En el mismo sentido se intentó verificar la presencia de diferencias individuales entre el sexo, la edad y el lugar de residencia de los sujetos evaluados. Los participantes son adolescentes entre las edades de 13 a 18 años (N= 1270) de tres regiones de la Argentina (Región Metropolitana, Noroeste y Patagonia). Los instrumentos administrados son la escala de bienestar (BIEPS-J), otras escalas tradicionales para la evaluación de la satisfacción (Escala SWLS y D-T) y un listado de síntomas psicopatológicos (SCL-90). Los resultados señalan que las escalas clásicas que evalúan satisfacción con la vida resultan indicadores poco válidos para una evaluación del bienestar psicológico autopercibido, considerando las dimensiones teóricas comentadas. Las variables género, edad y contexto sociocultural no parecen afectar la percepción subjetiva del bienestar psicológico.

Li, Jiayuan. "Towards a happier society? : subjective well-being and the happiness index of Guangdong, China." Thesis, University of Birmingham, 2015. http://etheses.bham.ac.uk//id/eprint/5635/.
Full textAbstract:
This thesis focuses attention on the initiative taken in China to balance the tremendous economic success of the past half-century with the social outcome of increased happiness for the population. Though counterintuitive, the evidence from various surveys suggests a generally declining trend in happiness in the country at a time when personal wealth has been increasing. The empirical analysis suggests that social comparison, hedonistic adaptation, and changes in other happiness determinants provide three potential explanations for the decline in self-reported happiness in China. In view of the profound policy implications of such findings, the second part of the thesis centers on the institutionalization of happiness reform, that is, how much the initiative of developing a happiness index in Guangdong has influenced policy and practice in public administration at local levels. Fieldwork undertaken in the province suggested a considerable gap between the rhetoric of commitment to such policy and the reality of public administrative practice. Theoretical insights from neo-institutionalism are explored and offered by way of accounting for the limited impact of this apparently ambitious public policy reform.

Full textAbstract:
Managed Mental Health Care (MMHC) began blanketing the United States when cost of care rose exponentially. MMHC is one avenue many employers and insurance companies have chosen to provide employees with mental health treatment at controlled costs. However, not all employers view supplying their employees with mental health treatment beneficial, as they do not know mental health problems can significantly decrease work productivity. Brown and Jones (2005) used the Social Role Scale (SR) of the Severe Outcome Questionnaire (SOQ) to estimate work productivity in employees under the assumption that the scale measures work productivity. The purpose of this study was to move closer to an estimation of the relationship between improved mental health and improved workplace functioning by examining the relationships among a self-report measure of mental health (i.e., the SR), a self-report measure of work productivity (i.e., the Work Productivity and Activity Impairment Scale [WPAI]), and objective measures of work productivity (i.e., the quality and timeliness of institutional records, supervisor ratings, and sick hours used). It was thought that understanding the relationships among these measures might assist in estimating the cost/benefit of investing in psychotherapy. Participants in this study were employees and inpatients at the Utah State Hospital. Statistical analyses indicated the SR did predict two WPAI scales (i.e., Presenteeism and Activity Impairment) for employees. Specific relationships among measures, and suggestions for future research, are discussed.

Full textAbstract:
The purpose of this thesis is to study if and how well implied volatility can predict realised volatility and returns on the OMXS30 index one month in the future. The findings are put in relation to how historical volatility can predict realised volatility and how changes in implied volatility can predict returns. The study covers the time period from 10th of May 2012 to 9th of February 2020 and the implied volatility used in the study is derived from an unweighted average of OMXS30 call and put option implied volatility. Six different OLS-regressions are performed to study the prediction capability of implied volatility. This study finds support of implied volatility to be a statistically significant estimate for future realised returns in a univariate regression. However, our results show that historical volatility performs slightly better predictions of realised volatility than implied volatility. These are contradictory results to the majority of the papers studied in this thesis. These papers share the common notion that implied volatility is superior to historical volatility in predicting realised volatility. Further our results show that implied volatility nor change in implied volatility are significant estimates to future realised returns and perform poorly as predictors. This result is supported by the larger part of previous research, which found implied volatility to be a weak predictor of returns.

Full textAbstract:
This study examines the association between collective identification with a rural communityfrom the northern coast of Peru, and the subjective, psychological and social expressions of well-being. These variables were analyzed in a sample of 80 community residents. Resultsshow significant associations between some components of collective identification and some expressions of well-being. A path analysis suggest that the general positive self-stereotype has a positive effect on collective self-esteem, while the self-stereotype of low efficacy reduces it. Meanwhile, collective self-esteem increases the degree of identification. Self-stereotype components influence different expressions of well-being. Thus, self-stereotype of low efficacy negatively affects social well-being, and self-stereotype of corruption negatively affects psychological well-being. Finally, social well-being influences psychological well-being, which in turn influences subjective well-being.Este estudio examina las relaciones entre la identificación colectiva con una comunidad rural y las expresiones subjetiva, psicológica y social del bienestar. Estas variables fueron analizadas en 80 pobladores de la comunidad. A través de un modelo estructural se observa que el autoestereotipo positivo general incide positivamente sobre la autoestima colectiva, mientras que el autoestereotipo de baja eficacia, atenúa la misma. Por su parte la autoestima colectiva incrementa el grado de identificación. Los componentes autoestereotípicos presentan relaciones de influencia con distintas expresiones del bienestar. Así, el autoestereotipo de baja eficacia incide negativamente en el bienestar social y el autoestereotipo de corrupción influye negativamente en el bienestar psicológico. Finalmente, se observa que el bienestar social influye en el bienestar psicológico, y este en el bienestar subjetivo.

Full textAbstract:
Introduction: Owing to its importance in the development and evaluation of health policies in favor of the general population, there is currently a greater interest in the study of well-being. Therefore, a valid and reliable measurement of well-being is necessary. In this context, this study evaluated the evidence of validity based on the internal structure, reliability, and factor invariance by sex of the General Well-Being Index (who-5 wbi). Materials and Methods: A total of 499 university students (female = 271; male = 228) from the city of Trujillo, Peru, participated in the study. A confirmatory factor analysis, reliability by internal consistency, and factor invariance by sex were performed using a multigroup analysis. Results: The confirmatory factor analysis indicated that the 5-dimensional model with 5 correlated errors of items 1 and 4 presented a good fit (χ² = 9.667 [gl = 4], p > 0.05; χ²/gl = 2.416; cfi = 0.994; rmsea = 0.053 [ic90% 0.006–0.097]; srmr = 0.018). In addition, acceptable reliability (ω = 0.758) and factor invariance by sex were reported. Conclusion: The who-5 wbi demonstrated empirical evidence in favor of validity based on internal structure, reliability of scores, and factor invariance that allow for a useful and rapid instrument for measuring subjective well-being in university students.

The Woodford Shale (Oklahoma, U.S.A.) is a prolific unconventional hydrocarbon resource. The Woodford has been shown to be heterogeneous in many geochemical, mineralogical, and rock mechanic properties across the state of Oklahoma, which presents a challenge to successful exploitation of this resource (Caldwell, 2014; Turner et al., 2015; Wiley, 2015; Zhang et al., 2017). Most prior studies of the Woodford Shale report properties from a single sample collected from a vertical well, which reports these values as a single point source on a distribution map. Studies using outcrop localities report lateral variations in several rock properties of the Woodford, but are limited to the short distances an outcrop provides (Turner et al., 2015). The main focus of this research is to determine whether rock properties important to the productivity of the Woodford Shale vary across a lateral well bore within the Woodford shale. Measurements of chemical and mineralogical compositions were performed on rock cutting samples from a single horizontal well path of the Carleigh 6H-32 across approximately one mile. The mineral makeup was determined by use of X-ray diffraction (XRD) and elemental concentrations were determined by hand-held X-ray fluorescence (HHXRF). What was found is that the Upper and Middle Woodford Shale are relatively homogeneous laterally. The lack of variation means that it’s possible to determine from which subgroup samples may have been taken. The geochemical data were used to calculate a mineral-based brittleness index (Wang and Gale, 2009), which was compared to the measured frack gradient across perforations of the Carleigh 6H-32 well. In addition, the total organic matter content (TOC) was approximated in the same samples using loss on ignition (LOI) methods. The calculated mineralogy within samples assigned to the Middle Woodford show some variability throughout the horizontal well, which leads to an associated variation in mineral brittleness index when using the Wang and Gale (2009) formula. The mineral based brittleness index correlates with observed fracture gradient during well completion. This suggests that the tendency to fracture is also variable along the well path, which should be considered during design of the well completion.

Full textAbstract:
The primary purpose of this thesis was to psychometrically evaluate the Irish version (English language) of the UK Health and Safety Executive's Management Standards Indicator Tool (ROI-MSITL a self-report survey instrument that assesses perceptions of stressors in the workplace. To that end, the thesis undertook a thorough examination of the ROI-MSIT's scales and items to appraise its criterion-related validity, construct validity, factor structure, reliability, and measurement invariance across gender. Associations between the ROI-MSIT and the WHO-Five Well-being Index (WHO-5) were also investigated in order to explore the salutogenic potential of the Management Standards' risk model, the secondary purpose of this thesis. The aim of Study I was to provide a preliminary investigation of the psychometric properties of the ROI-M5IT. In particular, the study examined the factor structure, internal consistency, and convergent validity (with the WHO-5) of the ROI-MSIT in order to determine its suitability for use in Ireland. Exploratory factor analysis revealed that the factor structure of the ROI-MSIT is practically identical to that of the Italian MSIT, consisting of six factors; the Demands, Control, Peer Support, Relationships, and Role factors were equiva lent to the original UK factors. As with the Italian version, the principal factor was a merger of the Manager Support and Change domains. Reliability analysis of the subscales revealed Cronbach's alpha scores ranging from .80 to .91. Finally, the ROI-MSIT's (six) subscales and WHO-5 were found to be positively correlated (r = .36-44, P <.001), while logistic regression analyses showed that increased scores on the individual items and subscales were associated with a decreased likelihood of being classified in the poor well-being category of the WHO-5 (score <13). Study II used confirmatory factor analysis (CFA) to assess competing measurement models of the ROIMSIT, including the seven-factor structure of the UK Indicator Tool. The construct reliability and internal consistency of the ROI-MSIT were also assessed, as were its convergent and discriminant validity. The seven-factor measurement model of the UK-MSIT provided the best fit to the data compared with a six-factor and one-factor measurement model. A second-order measurement model also proved to be of adequate fit. The construct reliability (CR) and internal consistency were excellent, as each factor achieved a CR and alpha score of .79 or more. The convergent and discriminant validity results were, on the other hand, disappointing, as several subscales failed to meet the minimum values necessary for demonstrating validity. The primary aim of Study III was to test the measurement invariance (MI) of the ROI-MSIT across gender. The seven-factor measurement model and items of the ROI-MSIT were tested for MI; multiple-group confirmatory factor analysis (MG-CFA) was used to test the model, while tests of differential item functioning (DIF) were applied to each item through ordinal logistic regression. The results of these analyses indicated that the ROI-MSIT is fully invariant across gender. The primary aim of Study IV was to investigate associations between scores on the ROI-MSIT and the likelihood of being categorised in the 'good wel l-being' category of the WHO-5 (total score >12). Correlation analysis revealed positive, moderate associations between the (uni-dimensional) ROI-MSIT and the WHO-5 (r = .53, P <.001). In the logistic regression analyses, those in the top ROI-MSIT scoring category were 18.44 times (95% CI: 14.46-23.50) more likely to be classified in the good well-being category of the WHO-5 than those in the bottom scoring group. Similarly, ordinal logistic regression revealed that those in the top category were 21.18 times (95% CI: 17.74-25.28) more likely to be in the good well-being category and flourishing category (WHO-5 score >19). Strong results were also found for the ROI -MSIT's subscales. Although additional research is needed to determine the full salutogenic potential of the Management Standards' risk model, the initial findings of Study IV suggest that following the approach may help employees experience positive mental states rather than just the absence of psychological harm. Small sh ifts in mean scores on the Management Standards Indicator Tool could potentially move the working population towards mental flourishing. The general conclusions of the studies are that a) the ROI-MSIT bears a very close resemb lance to the UK version, b) the ROI-MSIT is a valid and reliable questionnaire, and c) the Management Standards initiative may help employees (and working populations) experience greater 'positive mental health.' Further research is needed to validate the findings of the thesis.

Full textAbstract:
Magister Artium (Psychology) - MA(Psych)The construct of subjective well-being within child well-being and quality of life research has become increasingly prominent in recent years. Central to such developments is the question of to what extent children’s subjective experiences of well-being can be compared cross-culturally. Given the paucity of empirical research on the topic of cross-cultural comparisons, the importance of validating current measures of subjective well-being has been emphasized by many researchers as critical in contributing to the international dialogue. The aim of the current study was to test a measure of subjective well-being (the Personal Well-being Index – School Children) amongst a sample of children from Cape Town, Western Cape Province, South Africa. Given the diversity of experience between children from different language groups in South Africa, the study further aimed to determine the extent to which the measures are comparable across two language groups (Afrikaans and English). Data from the Children’s World Survey were used; and include a sample of 1004 children randomly selected from 15 schools within the Cape Town Metropole. Located within the goodness of fit theoretical framework, confirmatory factor analysis was used to test the overall fit structure and multi-group factor analysis, with Scalar and Metric invariance constraints. The results show appropriate fit structure for the overall model, with Scalar and Metric factor invariance tenable across language groups. The overall findings suggest that the Personal Well-being Index – School Children is appropriate for use with English and Afrikaans children in Western Cape Province, South Africa, and that scores between these groups can be compared by regressions, correlations, and means.

Full textAbstract:
This dissertation is composed of three essays; the first two examine the decisionmaking of potato producing households in Bolivia and the third examines well-being changes among Zimbabwe households. The first essay entitled “The role of risk mitigation in production efficiency: A case study of potato cultivation in the Bolivian Andes” estimates the costs of self-managing environmental risk through activity and environmental diversification. Risk management has the potential to reduce income variability but at the cost of increasing production inefficiency, which we measure employing a stochastic production frontier. Among variables capturing environmental diversification, discontinuity between fields has the most detrimental effect on production efficiency. Activity diversification, measured by the ratio of potato to total crop revenue, has a stronger impact on inefficiency and yield losses than any of the environmental diversification variables.
The second essay entitled “Determinants of market participation decisions and marketing choices in Bolivia” examines three decisions related to potato market participation: market entry, volume sold, and market choice. The first two are analyzed using a Heckman selection model. Results indicate that isolation, measured by population density and distance to markets, negatively impacts market entry. The most important determinant of quantity sold is land holding. Market choices are judged according to second-order stochastic dominance (SOSD). Market choices meeting the SOSD criterion are referred to as optimal marketing strategies as they have the higher expected payoff for a minimal income variance. Results suggest that the probability of selecting an optimal marketing strategy increases with quantity sold, access to market information, and access to liquidity while it decreases with distance to markets.
The third essay entitled “A profile of changes in well-being in Zimbabwe, 2001- 2007/8, using an asset index methodology” shows that it is possible to examine intertemporal and spatial changes in well-being in the absence of consumption expenditures data by using an asset index. The asset index was constructed using Polychoric Principal Component Analysis. Results indicate that poverty and extremely poverty grew significantly in rural Zimbabwe while in urban areas, poverty diminished and extreme poverty grew.Ph. D.

Chichinmanum weamu, traducido como yendo a contracorriente, describe una experiencia por la cual atraviesan muchos jóvenes indígenas universitarios al enfrentar situaciones que afectan su bienestar. Esta investigación analiza si las condiciones en las que estudiaban seis jóvenes awajún en la Universidad Nacional de la Amazonia Peruana garantizaban ese bienestar. Con este propósito, utilizamos una metodología cualitativa y diferentes técnicas etnográficas como entrevistas, grupos focales, observaciones e historias de vida. Argumentamos que estar bien significaba para los estudiantes awajún contar con todos los servicios básicos, bienes y recursos que incluyen relaciones cercanas con sus compañeros y docentes. Al observar dichos aspectos, concluimos que los estudiantes awajún no estaban satisfechos. Sin embargo, el capital social desarrollado a través de la Organización de Estudiantes de los Pueblos Indígenas de la Amazonia Peruana les garantizaba su sobrevivencia en Iquitos.This article analyzes if life conditions in the National University of the Peruvian Amazon assured six young Awajun their well-being. It ponders several questions; what is the emic meaning of being well?, Could young migrants satisfy their socio-economic and affective needs?, which are the strategies used to perform as students? To answer these questions, a qualitative methodology and different ethnographic techniques such as interviews, focus groups, observations and life stories were used. And different actors such as student colleagues, teachers, university authorities, were observed and interviewed. The expression chichinmanum weamu, translated from Awajún as going against the current, describes a situation that many young natives who try to become graduates go through. Young Awajun thought that being good meant having all the basic services, goods and resources needed to develop as students, which also implied having fluid relationships with peers and teachers. The study reached the conclusion that young Awajun were not entirely satisfied. However, the social capital developed through the Student Organization of the Indigenous Peoples of the Peruvian Amazon did ensure their survival in Iquitos.

Full textAbstract:
Philosophiae Doctor - PhDSchools, world-wide, have been regarded as important settings for health promotion and health education. Research indicate that schools constitute a crucial setting for programmes that aim at promoting the health of children, young adults, their families and their community, and could make a positive contribution to the overall health of the society. The psychosocial theory of human development proposes to understand and describe the importance of psychosocial health and well-being of children, in their different stages of development, across the life span, as well as how the different environments of the child's rearing could either add, or hinder, optimal development. Healthy Early Childhood Development, which includes physical, social-emotional, as well as linguistic/cognitive development, is fundamental to success and happiness, not only during childhood, but throughout the course of life. This study, therefore, aimed to design a School Health Index Score Card that assesses psychosocial health and well-being in Early Childhood Development at primary schools in the rural Western Cape. The School Well-Being Model serves as a conceptual framework for this study and is based on Allardt's Sociological Welfare Theory,which assesses well-being as an entity in a school setting. This model takes into account the impact of family, social relationships, personal self-fulfilment and health aspects of children. This study used a mixed methodological sequential explanatory design that consisted of two distinct phases (with 2 stages in each phase) within a participatory action research framework. A needs assessment and a systematic review was conducted in phase 1 followed by phase 2, action planning-design of a school health index score card and a Delphi technique study. Quantitative, numeric, data were collected and analysed using the Statistical Package for Social Sciences V23 (SPSS) for descriptive and inferential statistics first, while the qualitative data were collected and analysed secondly in sequence for this design. The qualitative process helped to explain, or elaborate, on the quantitative results obtained from the respondents by means of a self-administered questionnaire that consisted of three sections; demographical information and the adaptation of the (i) Pediatric Quality of Life Inventory (PedsQL) and (ii) Strengths and Difficulties Questionnaire. The data were collected from teachers, principals, community leaders, parents/primary caregivers, members of school governing bodies, school nurses, social workers, health promotion officers, experts in early childhood development and school psychologists of learners in Grade R to Grade 3 at three primary schools in the rural Western Cape, South Africa. The systematic review of previous studies revealed that, (i) instruments are often designed to identify physical ailments, the individual’s ability to adjust to particular situations, psychiatric diagnosis, educational and intellectual abilities, as well as the personal characteristics of children over their entire lifespan, (ii) that promotion of psychosocial health and well-being challenges in early development does promote positive child development outcomes in later life, and (iii) the use of a valid and reliable instrument to assess psychosocial health and well-being in schools could have a number of advantages for children, their families, teachers and the community. The findings of the current study also indicated that, (i) parents/primary perceived their children to be experiencing challenges in school functioning, social functioning and physical functioning continually and, (ii) teachers perceived the learners to be experiencing social behavioural, hyperactive and behavioural challenges continually at school. Schools play an integral part in the lives of children and their families, by supporting children to form social and emotional relationships at school. Overall, this current study suggested that the School Health Index Score Card was considered to be user friendly, as well as a useful tool to assess the psychosocial health and well-being challenges of learners at primary schools in a South African context.

Full textAbstract:
Urbane Gesundheit ist von globalem Interesse, da schon jetzt die Mehrheit der Menschen in Städten wohnt und dies zunehmend in Entwicklungsländern. Obwohl mentale Gesundheitsprobleme (z.B. Depressionen) in Entwicklungsländern stark verbreitet sind, wurden diese für die rasant anwachsenden Städte dieser Länder bisher nicht zufriedenstellend untersucht. Mit einem räumlich-epidemiologischen Ansatz werden in der vorliegenden Dissertation Faktoren identifiziert, welche das mentale Wohlbefinden der Slumbewohner Dhakas beeinflussen. Hierfür wurden Baseline Daten einer Kohortenstudie verwendet, welche Anfang 2009 in neun Slums in Dhaka durchgeführt wurde. Es wurden Daten von 1.938 Erwachsenen (≥15 Jahre) erhoben. Der WHO-5 Well-being Index wurde als Instrument zur Selbsteinschätzung des mentalen Wohlbefindens verwendet. Mentales Wohlbefinden war signifikant mit verschiedenen Faktoren der natürlichen Umwelt, der Sicherheit vor Überflutungen, sanitären Verhältnissen, sowie mit qualitativ hochwertiger, zufriedenstellender und beständiger Behausung assoziiert. Weitere mentale Gesundheitsassoziationen wurden in Bezug auf Bevölkerungsdichte, Zufriedenheit mit der Arbeitsstelle und mit der Einkommensgenerierung identifiziert, während für individuelle Faktoren wie Alter, Geschlecht, Krankheiten, Gesundheitswissen und Migrationshintergrund angepasst wurde. Räumliche Konzentrationen von gutem und schlechtem mentalem Wohlbefinden wurden festgestellt, welche auf massive Gesundheitsungleichheiten innerhalb der Slums hindeuten. Verschiedene Nachbarschaftskontexte wirken sich zudem in anderer Weise auf das Wohlbefinden aus als persönliche und Haushaltscharakteristika. In der Annahme, dass mentale Gesundheitsprobleme das Risiko physischer Krankheiten sowie die Unfallgefahr erhöhen, liefert diese Dissertation wichtige Informationen, um sowohl eine bessere Krankheitsversorgung als auch sinnvolle Krankheitspräventionsprogramme für die Slums von Dhaka und vergleichbarer Gebiete zu entwickeln.Urban health is of global concern because the majority of the world’s population lives in urban areas, mainly in the global south. Although mental health problems (e.g., depression) in developing countries are highly prevalent, such issues are not yet adequately addressed in the rapidly urbanising megacities of these countries, where a growing number of residents live in slums. Little is known about the spectrum and burden of mental disease in urban slums. Using a spatial-epidemiological approach, this thesis identifies factors that contribute to mental well-being in the slums of Dhaka, the capital of Bangladesh, which currently accommodates an estimated population of more than 14 million, including 3.4 million slum dwellers. The baseline data from a cohort study conducted in early 2009 in nine slums of Dhaka were used. Data were collected from 1,938 adults (≥15 years). The WHO-5 Well-being Index was used as a measure of self-rated mental well-being. It was found that mental well-being was significantly associated with various factors such as selected features of the natural environment, flood non-affectedness, sanitation, and housing quality, sufficiency and durability. Further associations with population density, job satisfaction, and income generation were identified while adjusting for individual factors such as age, gender, diseases, health knowledge, and migration. Spatial clusters of poor and good mental well-being among different population groups were detected and point to severe health disparities both within and between the slums. Diverse neighbourhood conditions affected mental well-being differently from personal and household level characteristics. Given that mental health conditions could elevate the risk for physical diseases and contribute to injuries, this thesis may provide crucial information for developing better health care and disease prevention programmes in Dhaka’s slums and other comparable settings.

The aim of this study is to explore the patterns of emotion recognition in Mexican bilinguals using the JACFEE (Matsumoto & Ekman, 1988). Previous cross cultural research has documented high agreement in judgments of facial expressions of emotion, however, none of the previous studies has included data from Mexican culture. Participants were 229 Mexican college students (mean age 21.79). Results indicate that each of the seven universal emotions: anger, contempt, disgust, fear, happiness, sadness and surprise was recognized by the participants above chance levels (p < .001), regardless of the gender or ethnicity of the posers. These findings replicate reported data on the high cross cultural agreement in emo- tion recognition (Ekman, 1994) and contribute to the increasing body of evidence regardingthe universality of emotions.Este estudio presenta un meta-análisis sobre la relación entre los valores de Schwartz y el bienestar subjetivo en distintos contextos culturales, con estudiantes, sus familiares e inmigrantes en España. Los resultados confirman una asociación significativa entre los valores y el bienestar. Auto trascendencia y apertura al cambio, y con menor intensidad, conservación, se asocian positivamente con mayor bienestar. Auto trascendencia se asocia con felicidad y satisfacción de forma positiva no homogénea, siendo los inmigrantes quienes presentan medias más bajas. Apertura al cambio se asocia con felicidad, siendo más fuerte la asociación en inmigrantes que en estudiantes. Los valores conservacionistas se asocian homogéneamente. Un segundo estudio sobre criterios de salud psicosocial y bienestar subjetivo -analizando un país sudamericano colectivista y jerárquico como Brasil, y otro europeo más individualista e igualitario como España- confirma que los valores conservacionistas, así como los de apertura al cambio y auto trascendencia, son deseables y favorecen el bienestar.

Full textAbstract:
Rates of obesity are predicted to increase, which is worrying given the association with adverse health outcomes. Cost of food or diet is one proposed contributor to an ‘obesogenic environment’. The “food price-obesity hypothesis” supposes that, with limited purchasing power, consumers may purchase energy-dense foods to obtain the maximum calories, resulting in excess energy intake. This thesis attempts to gauge whether obesity may be attributed to food prices. Firstly, the published literature was synthesised. Secondly, the study examined how income and cost of diet are implicated in excess energy intake, as implied by the body mass index (BMI) and dietary energy density (DED), of adults in the National Diet and Nutrition Survey (NDNS). The literature review revealed a heterogeneous body of studies that was generally supportive of the food price-obesity theory, but not conclusive. Studies of diet costs and DED overwhelmingly report a negative association. A limited number of studies investigating diet costs and BMI reported contradictory findings. The evidence linking income and DED was not strong. In the NDNS sample, income was found to be negatively associated with DED, BMI, and overweight/obesity. In addition, a negative association was observed between diet costs and DED. There was no association between whole diet costs and BMI. In contrast, using proportional food group costs revealed some significant associations. This suggests that measuring how people apportion their food budget, rather than how much the whole diet is worth, may be insightful. The thesis also addresses some methodological issues. Firstly, analyses demonstrate how equivalizing household income to take into account household composition can impact on findings. Secondly, a comparison of diet costing methods is presented. Despite methodological challenges, the findings presented in the thesis suggest there is merit in pursuing research into diet costs, with many unexplored opportunities in this emerging field.

ENGLISH ABSTRACT: Genetic screening to improve obesity treatment outcomes is available despite the lack of conclusive evidence, specifically for Caucasian South Africans, in this regard. The aim of this study was to investigate the association between genotype (seven polymorphisms) and body mass index (BMI), health and lifestyle indicators in a cross-sectional sample of overweight/obese Caucasian adults (n=133), as well as the association between genotype and weight loss outcomes following an intervention (n=88) using a quasi experimental study design (time-series). The intervention consisted of a 24-week conservative weight loss programme that included dietary, physical activity and behavioural components. The primary null hypothesis for the cross-sectional sample, namely that there is no association between genotype and BMI, has not been rejected. A number of the secondary/exploratory hypotheses were rejected of which the most plausible associations (based on support by the literature and a physiological basis for the findng) are: 1) the mutant TT homozygotes of the GNB3 C825T polymorphism may have a higher risk to develop the metabolic syndrome (MetS) as they had significantly higher fasting triglyceride and glucose levels, a higher number of traits that met the diagnostic cut-off criteria for MetS and higher number of these subjects was diagnosed with MetS compared to the wild-type C-allele carriers; and 2) subjects with mutant alleles of either the FTO rs1421085 or rs17817449 polymorphisms may have poorer eating behaviours (a higher rigid control, habitual and emotional disinhibition, perceived hunger and internal locus for hunger) and higher intake of high-fat foods. The primary null hypothesis for the intervention sample, namely that there is no association between genotype and weight loss outcome, was not rejected for the FABP2 Ala54Thr, INSIG2 rs7566605, FTO rs1421085, ADRB3 Trp64Arg and GNB3 C825T polymorphisms. However, it was rejected in some instances indicating the following associations: 1) The wild-type TT homozygotes of the FTO rs17817449 polymorphism lost significantly more weight during the first two months of the program compared to the mutant allele carriers (this is a novel finding); 2) The wild-type Arg16Arg homozygotes of the ADRB2 Arg16Gly polymorphism lost significantly more weight during the first month of the program compared to the mutant allele carriers (this finding is supported by one other intervention study); 3) Subjects with a mutant C-allele of the INSIG2 rs7566605 polymorphism and a mutant Gly16-allele of the ADRB2 Arg16Gly polymorphism lost significantly less weight over the six month intervention period (this is a novel genegene interaction finding). A number of secondary/exploratory hypotheses were rejected, of which the most plausible finding include that the improvement in emotional disinhibition in the wild-type TT subjects of the FTO rs1421085 polymorphism was associated with a more pronounced decrease in BMI over the six month weight loss period. The integration of the results from this study with the literature indicates that there is insufficient evidence at this stage for genetic screening of the polymorphisms investigated in this study and the provision of evidence-based personalized recommendations for weight loss in obese individuals. It is recommended that these associations should be viewed as priority in future research.
AFRIKAANSE OPSOMMING: Genetiese sifting om die resultate van vetsug behandeling te verbeter is beskikbaar ten spyte van ‘n tekort aan genoegsame bewyse, spesifiek ten opsigte van Kaukasiërs van Suid-Afrika. Die doel van hierdie studie was om die assosiasie tussen genotipe (sewe polimorfismes) en liggaamsmassa indeks (LMI), gesondheid en lewenstyl indikatore in ‘n dwarssnit (cross-sectional) steekproef van oorgewig/vetsugtige Kaukasiër volwassenes (n=133) te ondersoek, asook die assosiasie tussen genotipe en gewigsverlies uitkomste na afloop van ‘n intervensie (n=88) in ‘n kwasi-eksperimentele studie ontwerp (tydreeks). Die intervensie het bestaan uit ‘n 24-week konserwatiewe gewigsverlies program met dieet, fisieke aktiwiteit en gedragskomponente. Die primêre nul hipotese vir die dwarsnit steekproef, naamlik dat daar geen assosiasie tussen genotipe en LMI is nie, is nie verwerp nie. ‘n Aantal sekondêre/spekulatiewe hipotesis is verwerp waarvan die mees geloofwaardige assosiasies (gebasseer op ondersteuning van die literatuur en ‘n fisiologiese basis vir die bevinding) die volgende insluit: 1) die mutante TT homosigote van die GNB3 C825T polimorfisme het moontlik ‘n hoër risiko vir die ontwikkeling van die metaboliese sindroom (MetS) aangesien hulle betekenisvolle hoër vastende trigliseriede en glukose vlakke gehad het, ‘n grooter aantal kenmerke gehad het wat aan die diagnostiese afsnykriteria vir MetS voldoen en ‘n grooter aantal van hierdie persone was met MetS gediagnoseer in vergelyking met die wilde-tipe C-alleel draers; en 2) persone met die mutante allele van die FTO rs1421085 of rs17817449 polimorfismes het moontlik ‘n swakker eetgedrag (‘n hoër rigiede kontrole, gewoonte en emosionele disinhibisie, waarneembare honger en interne lokus van honger) en ‘n hoër inname van hoë-vet voedsel. Die primêre nul hipotese vir die intervensie steekproef, naamlik dat daar geen assosiasie tussen genotipe en gewigsverlies uitkomste is nie, is nie vir die FABP2 Ala54Thr, INSIG2 rs7566605, FTO rs1421085, ADRB3 Trp64Arg en GNB3 C825T polimorfismes verwerp nie. Dit was egter in sommige gevalle vir die volgende assosiasies verwerp: 1) Die wilde-tipe TT homosigote van die FTO rs17817449 polimorfisme het betekenisvol meer gewig in die eerste twee maande van die program verloor in vergelyking met die mutante alleel draers (dit is ‘n nuwe bevinding); 2) Die wilde-tipe Arg16Arg homosigote van die ADRB2 Arg16Gly polimorfisme het betekenisvol meer gewig gedurende die eerste maand van die program verloor in vergelyking met die mutante alleel draers (hierdie bevinding word ondersteun deur een ander intervensie studie); 3) Persone met ‘n mutante C-alleel van die INSIG2 rs7566605 polimorfisme en ‘n mutante Gly16-allele van die ADRB2 Arg16Gly polimorfisme het minder gewig tydens die ses maande intervensie periode verloor (dit is ‘n nuwe geen-geen interaksie bevinding). ‘n Aantal sekondêre/ spekulatiewe hipoteses is verwerp, waarvan die mees geloofwaardigste bevinding insluit dat ‘n verbetering in emosionele disinhibisie van die wild-tipe TT persone van die FTO rs1421085 polimorfisme geassosieer was met ‘n meer prominente daling in LMI oor die ses maande gewigsverlies periode. Die integrasie van die resultate van hierdie navorsing met die literatuur dui aan dat daar op hierdie stadium onvoldoende bewyse vir genetiese sifting en die voorsiening van bewys-gebasseerde persoonlike aanbevelings vir gewigsverlies in vetsugtig individue bestaan vir die polimorfismes wat ondersoek is. Dit word aanbeveel dat hierdie assosiasies as prioriteit in toekomstige navorsing beskou moet word.

Full textAbstract:
Sweden have faced decreasing groundwater storage with critical low groundwater levels for several years. Gotland is one example with issues of providing freshwater due to the low groundwater levels. These circumstances can be related to impacts caused by early agriculture development, an increased demand of freshwater and climate change. There is a need in this region to increase the groundwater storage to ensure enough freshwater. The aim of the study is to increase freshwater storage. Digital geographical information system (GIS) was chosen as a tool in this study in order to cover large geographical areas. The study was divided into two parts, with focus to determine hydrological and hydrogeological conditions and to identify suitable areas where groundwater storage could be increased. The first part studied: specific capacity, groundwater storage, groundwater balance and topographic wetness index. The second part locked at four methods to increase freshwater storage: Lakes, controlled drainage, wetland and subsurface dam. The result tells us that lakes have the potential to provide freshwater for the municipal distribution network. The controlled drainage method has the ability reduce the outflow of surface water and to increase the groundwater infiltration. Earlier drained wetland areas was identified which could serve as freshwater storage. Suitable areas for subsurface dams were identified. They could work as a large groundwater storage as a decentralized system with the ability to provide groundwater for wells that are spread out. However the identified areas for each methods needs further investigations in more detail to determine the accuracy of the results.

Full textAbstract:
Cette thèse s'intéresse à l'usage des auto-évaluations (de santé, satisfaction. . . Sur des échelles numériques ou verbales) en économie. Le premier chapitre utilise des déclarations de bien-être afin d'étudier l'ampleur des comparaisons économiques en Inde, et notamment entre castes. Les résultats obtenus confinent que les comparaisons ont une effet délétère sur le bien-être. Par ailleurs, il apparaît que les individus de basses castes sont frustrés par les succès économiques des castes plus élevées, alors que ces dernières ne tirent aucune satisfaction de la situation des basses castes. Le second chapitre s'intéresse à la mesure dans laquelle les individus peuvent différer dans leur façon d'utiliser les échelles déclaratives pour déclarer leur bien-être. Il propose une nouvelle méthode pour détecter cette hétérogénéité déclarative, et pour en corriger les effets. Cette méthode est utilisée pour vérifier si les enquêtés diffèrent dans leur utilisation de l'échelle selon leur niveau de revenu. Il apparaît que les enquêtés les plus riches sous-reportent les variations de leur bien-être, ce qui tend à biaiser fortement les analyses Le troisième chapitre étudie les causes de l'hétérogénéité déclarative, en se concentrant sur la santé déclarée. Il évalue empiriquement l'hypothèse selon laquelle l'interprétation de l'échelle dépend de la répartition de la santé dans le groupe des pairs. Cette hypothèse apparaît être globalement valide. Il apparaît aussi que d'autres mécanismes peuvent jouer. Un dernier résultat est que si cette hétérogénéité déclarative induit un biais, ce biais reste limité dans la plupart des situations d'intérêtThis dissertation is built around the notion of self-reports (reports of health, satisfaction. . . On numerical or verbal scales) in economics. The first chapter uses self-reports of well-being to study economic comparisons in India, with a special focus on comparisons between rival castes. Comparisons turn to be detrimental to well-being. Besides, low-caste individuals feel deprived from the economic successes of higher-caste Indians, whereas these latter appear to derive no satisfaction from the low consumption of low castes. The second chapter studies the extent to which respondents differ in their use of the well-being reporting scale. A new method is proposed to detect and correct for this reporting heterogeneity. This method is used to check whether respondents differ in their reporting behavior depending on their income. It appears that richer respondents under¬report the variations in their well-being, which in turn biases strongly analyses based on well-being reports. The third chapter focuses on the causes of reporting heterogeneity, and-çonsiders the case of health reporting. This chapter assesses empirically the hypothesis according to which the interpretation of the response scale changes with the distribution of health in the peer group. This hypothesis appears to be generally verified. It also appears that other mechanisms may influence the use of the response scale. Besides, even though this reporting heterogeneity may bias analyses based on self-reports, the bias appears to remain limited for most purposes

Full textAbstract:
We study the Weyl representation of metaplectic operators associated to a symplectic matrix having no non-trivial fixed point, and justify a formula suggested in earlier work of Mehlig and Wilkinson. We give precise calculations of the associated Maslov-type indices; these indices intervene in a crucial way in Gutzwiller’s formula of semiclassical mechanics, and are simply related to an index defined by Conley and Zehnder.

Universidade Federal do CearÃAccording to the United Nations (UN), the target of one of the objectives Development Goals of halving the number of people without access to water drinking was reached - however, 768 million people still do not enjoy this advance overall, especially in rural areas. In this context, the population of Iguape, a district of municipality of Aquiraz-EC, is part of this minority, lacking sewage and supply for water distribution network. Thus, a study was performed to During the year 2013 with the objective of determining if the water wells used by population - the main source of those goods - was in accordance with the parameters of potability provided for in the regulations. The results show that for the plurality of wells human consumption have parameters outside the limits accepted by the existing laws - presence of E. coli, for example. As a reference for this study the Quality Index Canadian Council of Ministers of the Environment was employed to facilitate the Understanding of the data set and revealed that the ten wells monitored only one presents water quality rated as Good.

Full textAbstract:
In this thesis, we investigate supersymmetric quantum mechanics (SUSYQM) and its relation to index theorems and equivariant cohomology. We define some basic constructions on super vector spaces in order to set the language for the rest of the thesis. The path integral in quantum mechanics is reviewed together with some related calculational methods and we give a path integral expression for the Witten index. Thereafter, we discuss the structure of SUSYQM in general. One shows that the Witten index can be taken to be the difference in dimension of the bosonic and fermionic zero energy eigenspaces. In the subsequent section, we derive index theorems. The models investigated are the supersymmetric non-linear sigma models with one or two supercharges. The former produces the index theorem for the spin-complex and the latter the Chern-Gauss-Bonnet Theorem. We then generalise to the case when a group action (by a compact connected Lie group) is included and want to consider the orbit space as the underlying space, in which case equivariant cohomology is introduced. In particular, the Weil and Cartan models are investigated and SUSYQM Lagrangians are derived using the obtained differentials. The goal was to relate this to gauge quantum mechanics, which was unfortunately not successful. However, what was shown was that the Euler characteristics of a closed oriented manifold and its homotopy quotient by U(1)n coincide.

This study examined the BMI, dietary habits, body perception, physical activity patterns, and nutrition knowledge and opinions of 599 fourth grade public school students in Wells County, Indiana, in 2003-04 and 2005-06. Participants completed the School Physical Activity and Nutrition (SPAN) survey and had their height and weight measured. Almost half (49.9%) of the participants were at risk for or were overweight. More than one-quarter (29.1 %; n=91) normal weight students perceived they did not weigh enough. At risk for overweight children were more likely to participate in exercise that did not raise their heart rate than normal weight children. Normal weight children participated in more cardiovascular-raising activity than overweight children did. Students engaged in significantly more cardiovascular exercise in 2005-06 than in 2003-04. Students "usually" spent 3.4 ± 2.0 hours per day in screen time. Interventions that encourage healthy eating and physical activity would benefit students in this community.Department of Family and Consumer Sciences

In 2001, the percentage of fourth grade students who were overweight (26%) in Wells County, Indiana was twice the national average (13%). A Robert Wood Johnson Local Initiative Funding Partners grant was submitted and received to provide this community with resources to help combat unhealthy lifestyles. The purpose of this study was to examine differences in body mass index, food choices and nutrition knowledge and attitudes of fourth grade students in Wells County to determine if the prevalence of overweight had been reduced, and provide insight into children's food choices and nutrition knowledge. Of the 1,347 fourth grade students who completed the SPAN questionnaire over the four years, 23 percent were overweight. Over the four years, the prevalence of overweight did not increase to higher levels, providing modest support for the impact of Operation Wellness on students' weight. The students in this rural community ate fewer meals, snacked more frequently, did not eat enough fruits or vegetables, and ate too many high-fat/high-sugar foods compared to recommended standards. Students from the Southern Wells School District were significantly more aware of the relationship between diet, weight, and health than students in the other two school districts.Department of Family and Consumer Sciences

Resumo: Neste trabalho é proposto um parâmetro, denominado de índice de desempenho do sistema, que permite estudar o desempenho de poços de petróleo. Um diferencial deste parâmetro é que ele utiliza dados reais e abundantes de campo que são medidos periodicamente. Tal índice permite, por exemplo, avaliar o desempenho e as tecnologias utilizadas nos poços. Usando este índice, verificou-se a influência da geometria do poço para um mesmo campo e uma mesma zona produtora, comparando o desempenho dos poços verticais, direcionais e horizontais. Comparou-se também o desempenho do tipo de contenção de areia para esse mesmo campo e essa mesma zona produtora. Os dados utilizados neste trabalho foram gentilmente fornecidos pela Petrobras.
Abstract: In this work a new parameter called the System Performance Index is proposed, which allows a more profound study of the performance of petroleum wells. An outstanding characteristic of this parameter is that it uses a large amount of field data measured periodically. This index allows the assessing of the performance and technologies used in the wells. This study presents a comparison of the performance of vertical, directional and horizontal wells. The sand control technologies used in the wells are also evaluated. Finally, the proposed parameter enables a practical analysis that can be implemented as a strategic tool for oilfield, performance and optimization studies. Data used in this work were kindly supplied by Petrobras.
