Philosophiae Doctor - PhD / This study focused on the 16PF (SA 92), a personality questionnaire that was developed in the USA and adapted for South African conditions. The main aim of the study was to determine whether the scores of the 16PF are comparable in a cross-cultural setting in South Africa. The influence of age, language, socio-economic status and gender on the scores were also determined. The sample consisted of black, white, coloured, and Indian university students and were drawn from the University of Western Cape, University of Pretoria, University of Durban- Westville, and University of Natal To achieve the aims outlined construct comparability studies and item comparability studies were conducted. In addition, descriptive statistics were also calculated to provide a general picture of the performance of the various sub-samples. A qualitative study was also conducted to determine some of the reasons for the occurrence of item incomparability of the racial sub-sample. The results showed that the racial variable had the greatest influence on the scores obtained. Problems existed with the construct and item comparability of the 16PF when the different race groups were compared. In addition, significant mean differences were also found on the majority of factors when the scores of the different race groups were compared. The results of the qualitative study showed that participants whose home language was not English or Afrikaans had difficulty in understanding many of the words and the construction of sentences contained in the 16PF. The implications of using the 16PF in South Africa, with its multicultural population was outlined, taking the new labour legislation pertaining to selection into consideration. Finally, a number of options for test users, and users of the 16PF in particular were presented.

Objective: To assess occupational tobacco use and the impact of a tobacco-free policy in the Central Appalachia, an environment characterized by high tobacco use and production. Methods: This study was an Internet-based survey conducted on 2,318 university employees. Descriptive, chi-square, and logistic regression statistics were performed. Unadjusted and adjusted odds ratios (AOR) with respective 95 % confidence intervals (CI) were reported. Results: The survey response rate was 50.8 %; of the respondents, 9.0 % were current smokers. Smoking prevalence among faculty, administrators/professionals, and clerical/support staff was 6.1, 8.1, and 13.1 %, respectively. While those respondents aged 30-39 years showed a significantly increased likelihood of being a current smoker (AOR 5.64, 95 % CI 1.31-9.26), knowledge that secondhand smoke is harmful (AOR 0.22, 95 % CI 0.07-0.70) and support for tobacco-free policy (AOR 0.11, 95 % CI 0.04-0.27) decreased the likelihood. Conclusion: Low tobacco use among faculty and administrators confirmed the relationship between tobacco use and socio-economic status, even in a tobacco-producing environment. Disaggregation of tobacco use data assists the public health community in the efficient allocation of efforts and resources for cessation programs to reduce tobacco use in such environments.

In 1994, Tennessee, the third largest tobacco-producing state in the U.S., preempted tobacco regulation. However, in 2005, higher educational institutions were exempted from this preemption and the 2007 Non-Smoker Protection Act required educational facilities to create smoke-free environment. To this date, while all higher educational institutions have some sort of smoke-free policy, East Tennessee State University is the only public institution with a tobacco-free policy. We investigated attitudes and behaviors of the university personnel, the most stable segment of the population, toward the policy and compliance with it using an internet-based survey. All employees (2,318) were invited to participate in a survey; 58% responded. Bivariate analyses found 79% of the respondents favored the policy. Multiple variable logistic regression analyses found support for the policy was higher among females [OR = 3.14; 95% CI (1.68, 5.86)], administrators/professionals [OR = 3.47; 95% CI (1.78, 6.74)], faculty [OR = 2.69; 95% CI (1.31, 5.53)] and those affiliated with the College of Medicine [OR = 4.14; 95% CI (1.45, 7.85)]. While only 67 employees (5.6% of sample) reported they have not complied with the policy, around 80.8% reported observing someone engaged in non-compliance. The high level of support for the policy suggests it should be promoted throughout the higher education system and nationwide. At the same time, in preemptive states, higher educational institutions should be targeted as venues for strong tobacco-free policies. The gap in compliance, however, implies in tobacco-friendly environments, a tobacco-free campus policy with no reporting and enforcement mechanisms could lead to high levels of non-compliance.

Detta arbete har, med ett kvantitativt arbetssätt, undersökt hur socioekonomisk ojämlikhet kan påverka matematikutbildning på grundskolan. Syftet med detta arbete är att undersöka hur 15-åriga högstadieelever på skolor med högre respektive lägre genomsnittlig socioekonomisk profil upplever matematikundervisningen. Forskningsfrågorna handlar om hur elever upplever eget intresse och svårighet inom matematik, och hur elever upplever förväntningar från föräldrar och lärare samt deras egna mål på slutbetyg i matematik. För att beskriva skolornas socioekonomiska profil, användes föräldrarnas utbildningsbakgrund utifrån skolverkets SALSA-undersökning. Digitala enkäter i Google formulär användes i datainsamling för detta arbete. Univariata analyser med statistiska tabeller och signifikanstest (Wilcoxon test) används i dataanalysen. Totalt 19 elever på skolan med högre socioekonomisk status och 70 elever på skolan med lägre socioekonomisk status har deltagit i enkätundersökningen. Resultaten visar att elever på skolan med lägre socioekonomisk status upplever större förväntningar från föräldrar på deras betyg i matematik. Resultaten visar också att jämfört med elever på skolan med lägre socioekonomisk status, så tycker elever på skolan med högre socioekonomisk profil att matematik är enklare och att några matematiska områden som ingår i det centrala innehållet är mer intressanta. De matematiska områdena som taluppfattning, samband och förändring samt sannolikhet och statistik påverkas mest av elevers socioekonomisk status. Socioekonomisk status kan även påverka elevers gymnasieval där elever på skolan med högre socioekonomisk status har betydande högre vilja att söka gymnasieprogram som kräver matematisk kunskap. / This work has, with a quantitative approach, investigated how socio-economic inequality can affect mathematics education in primary school. The purpose of this work was to investigate how 15-year-old students at schools with higher and lower average socio-economic profile experience mathematics teaching. The research questions were how students experience their own interest and difficulty in mathematics, and how students experience expectations from parents and teachers as well as their own goals for final grades in mathematics. To describe the schools’ 'socio-economic profile, the parents' educational background was used based on the National Agency for Education's SALSA survey. Digital surveys in Google Forms were used as a data collection method. Univariate analysis with statistical tables and significance tests (Wilcoxon test) are applied in the data analysis. A total of 19 students at the school with higher socio-economic status and 70 students at the school with lower socio-economic status have participated in the survey. The results show that students at school with lower socio-economic status experience greater expectations from parents of their grades in mathematics. The results also show that compared with students at the school with a lower socio-economic status, students at the school with a higher socio-economic profile think that mathematics is simpler and that some mathematical areas that are included in the central content are more interesting. The mathematical areas such as number perception, connection and change as well as probability and statistics are most affected by students' socio-economic status. Socio-economic status can also affect students' upper secondary school choices, where students at the school with a higher socio-economic status have a significantly higher willingness to apply for upper secondary school programs that require mathematical knowledge.

Humans, like all animal species, are subject to Bergmann's (1847) and Allen's (1877) environmental rules which summarize physical adaptations to the natural environment. However, humans are in addition cultural animals and other bio-cultural factors such as social, economic and political status, general health, and nutrition, have a noticeable influence on stature and body proportions. Importantly, socio-economic status has a powerful influence on stature, which has been used to elucidate status differences in past societies (Bogin and Loucky, 1997; Floud et al., 1990; Schutkowski, 2000a). Furthermore, bio-cultural factors influence all dimensions of the human body, including weight, relative limb length, and relative length of the different limb segments. Given minimal migration and shared natural environments, all populations in this study, coming as they do from the last 2000 years of English history, should demonstrate similar morphology (c. f Ruff, 1994) if climatic variables were the only influence on stature and body proportions. In order to assess such bio-cultural factors in individuals from archaeological populations, skeletal populations from sites such as known leprosaria and medieval hospitals, rural and urban parish cemeteries, victims from the battle of Towton in A. D. 1461, and individuals from monastic cemeteries were analysed. The osteometric data from these populations were assessedfo r within and between population variability and indicate effects of bio-cultural factors on attained body proportions and stature. The results indicate a strong relationship between bio-cultural factors and body proportions, body mass index, prevalence of pathologies, sexual dimorphism, secular trend, and general stature from Roman times to the post-medieval period. The usefulness of stature, weight, and physical indices as markers of the bio-cultural environment is demonstrated. The main findings include: a greater sensitivity to external stressors in the males rather than the females of the analysed populations, rendering male statures more susceptible to varying bio-cultural conditions; a potential for very tall stature has existed in the analysed populations but was only realised. in very high status individuals in medieval times, and from the beginning 20'h century with better socio-economic conditions for the population at large; a less stratified socio-political environment, as in the late Anglo-Saxon period resulted in taller average male statures that a more stratified one, such as the medieval Nation-States; and medieval monastic institutions could have high status, e.g., the Gilbertines, or lower status, such as the mendicant orders, while leprosaria had the lowest status of all. / Ministere de la Culture, de l'Enseignement Superieur et de la Recherche, Luxembourg; Department of Archaeological Sciences, University of Bradford; Andy Jagger Fund; Francis Raymond Hudson Memorial Fund

My dissertation is composed of an introductory chapter followed by three independent chapters focusing on two themes: health and retirement. The last chapter concludes. After the introductory chapter, the second chapter investigates whether self reported general stress is a mediator in the relationship between socio-economic status (SES) and health. I use a six-year long panel of the Canadian Survey of Labour and Income Dynamics and employ dynamic econometric modelling techniques to study men and women who are major income earners in their families. I find little evidence that general stress is a pathway from SES to health. While the results suggest a strong negative association between stress and health for both men and women, they provide little support to the hypothesis of a significant effect of income on stress, consistent with the direction of the SES-health gradient. The third chapter studies whether self-assessed health status (SAH) contains information about future mortality and morbidity, beyond the information that is contained in standard "observable" characteristics of individuals (including pre-existing diagnosed medical conditions). Using a ten-year span of the Canadian National Population Health Survey, we find evidence that SAH does contain private information for future mortality and morbidity. Moreover, the extra information in SAH is greater at older ages. Our results suggest that a shift from defined benefit to defined contribution pension arrangements may carry with it the cost of exacerbated adverse selection in the market for annuities, especially at older ages. That would make it more difficult for older individuals to insure longevity risk. The fourth chapter looks at whether differences in early retirement pathways are associated with differences in post-retirement outcomes of health, stress and dwelling tenure. I use a 5 ample of men from the Canadian Survey of Labour and Income Dynamics, years 1996 to 2004. I find that differences in pre-retirement health indicators (such as self-assessed health and disability), as pathways to early retirement, are likely to be associated with differences in post-retirement health and stress. In addition, the results suggest that "involuntary" retirees (men who may have retired because of health and/or health related coniitions) are more likely to experience worse post-retirement outcomes (in terms of health and stress) than men who retire "voluntarily". Retirement circumstances are found to have no statistically significant effect on dwelling tenure. / Thesis / Doctor of Philosophy (PhD)
