The general purpose of this study was to explore the perception of discrimination under the middle managers in a selected South African mining company, as well as the associated impacts thereof on the individual and organisation. Although discrimination is a global phenomenon with a vast amount of scientific studies conducted on this topic, literature remains rather silent on the prevalence of discrimination among middle managers; especially within the South African mining industry. Organisational discrimination is defined as actions within an organisation which are biased towards certain individuals or groups. Literature suggests that discrimination is still very prevalent within organisations, both locally and internationally. It is typically influenced by aspects such as culture, and human resources practices and systems. The impacts are widespread with specific impacts on the individual’s mental or physical health, as well as productivity. South Africa however implemented a plethora of legislative measures to redress past inequalities and eliminate discrimination in its current form. This study followed a qualitative approach by means of a survey conducted through an open-ended questionnaire. The results indicated a high personal experience of discrimination within the specific mining company amongst the middle management team members. Their perception of discrimination towards their colleagues was also measured as above average. This exposure to discrimination impacted on their productivity and to a lesser extent on their personal well-being. Their perception of the potential impacts of this discrimination was reportedly higher than their actual experience thereof. The main discriminatory actions associated with this perception was centred on the notion, namely that middle managers were not recognised nor rewarded within this company. General benefits were withheld and expected promotions denied. The study’s results also confirm the perception that discrimination towards the middle management team will ultimately impact on the company’s overall performance. The study suggests that this high level, as well as the specific types of discrimination within this mining company, is related to a company specific culture. It further suggests that it is also exacerbated by the current socio-political reforms within the South African mining industry. The study concludes by suggesting that the perception of discrimination within a company is as harmful as the event itself, and should therefore form an integral part of any internal programme aimed at addressing this issue. / MBA, North-West University, Potchefstroom Campus, 2015

Doctor of Philosophy / Department of Geography / Bimal K. Paul / This research set out to better understand the impact of socioeconomic characteristics, environmental risk, and the built environment on health in Mobile County, Alabama. A multilevel statistical analysis was used to identify those characteristics that had the greatest impact on health. The variables determined to be the most significant in defining health in Mobile County were used in the development of a health inequity index (HIQ). The index was used to identify the zip code tabulation areas (ZCTAs) in Mobile County that were likely to exhibit greater health inequality, and as a result, a higher potential for health inequity. In this study, a mailed survey on the built environment and health was conducted to gain a better understanding of the characteristics of individual residences, perceptions of individuals in regards to neighborhood health, citizen activism, and the environmental justice movement. Because there was a low response rate for the mailed surveys, fieldwork with face-to-face interviews was conducted in July, 2009. In conjunction with the survey data, mortality data obtained from the Alabama Department of Public Health was incorporated into the multilevel analysis. Using crude death rate, cause-specific death rate for cancer, and cause-specific death rate for heart disease as dependent variables and factors associated with socioeconomic status, environmental risk, and the built environment as independent variables, multiple linear regression was performed. The results of the multiple linear regression identified factors of socioeconomic status, environmental risk, and the built environment that had the greatest impact on health in Mobile County. Geographically weighted regression was performed to test local model strength by ZCTA in Mobile County. It was determined that the health inequity index developed as a result of the multilevel analysis was a reasonable measure of population health. Calculations of HIQ for each ZCTA in Mobile County helped to identify those ZCTAs most in need of intervention. The ZCTAs with high HIQ values were also those where the built environment was extremely poor, indicating that health is impacted by the places where people live.

This thesis is concerned with two main questions. Do systemic banking crises substantially affect the income distribution in a country? Is income inequality a destabilising factor for the macro-economy? In order to answer the first question, this thesis examines a panel of 26 countries since 1900 and assembles a new database of crises, finding that the impact of major banking crises on the national income shares detained by the income groups within the richest decile is mostly small in magnitude. Indeed, the estimated impact is never bigger than a standard deviation of the specific top shares under investigation. Results are also confirmed in a separate analysis for the United States and are robust to a series of checks. These findings lend indirect support to the structuralist hypothesis that only substantial changes in government policies and institutional frameworks can bring about radical changes in income distribution. The analysis also highlights interesting heterogeneity across different income groups, country groups and time periods. The second question is addressed by making use of a newly assembled database on different dimensions of economic inequality. The new data helps to reject the statistical validity of the hypotheses that either growing inequality or a high level of inequality may systematically precede the onset of major banking crises. In addition, simulations based on the UK Family Expenditure Survey data find that even a full equalisation of income would increase the aggregate consumption by 3 percentage points at most. These findings, taken together, point out that an increase in income inequality may not concur to reduce the pressure on aggregate demand or be adduced as a structural factor of financial instability. Nonetheless, the evidence is not yet clear cut as the work further documents that periods of increasing income inequality in the UK were also associated with a reduction of the saving rates across the whole income distribution since 1968. The analysis contends that such evidence of under-saving behaviour may be consistent with the relative income hypothesis and some of its recent formulations such as the ’expenditure cascades’ theory.

The three constituent chapters of this thesis tackle independent, self-contained research questions, all concerning welfare economics in general and its application to climate change policy in particular. Climate change is a policy problem for which the costs and benefits are distributed unequally across space and time, as well as one involving a high degree of uncertainty. Therefore, cost-benefit analysis of climate policy ought to be based on a welfare function that is sufficiently sophisticated to incorporate the three dimensions of aggregation: time, risk and space. Chapter 1 is an axiomatic treatment of a stylised model in which all three dimensions appear. The main result is a functional representation of the social welfare function for policy assessment in such situations. Chapter 2 is a numerical mitigation policy analysis. I modify William Nordhaus' RICE-2010 model by replacing his social welfare function with one that allows for different degrees of inequality aversion along the regional and inter-temporal dimension. I find that, holding the inter-temporal coefficient of inequality aversion fixed, performing the optimisation with a greater degree of regional inequality reduces the optimal carbon tax relative to treating the world as a single aggregate consumer. In Chapter 3 I analyse climate policy from the point of view of intergenerational transfers. I propose a system of transfers that allows future generations to compensate the current one for its mitigation effort and demonstrate the effects in an OLG model. When the marginal benefit to a - possibly distant - future generation is greater than the cost of compensating the current generation for its abatement effort, a Pareto improvement is possible by a combination of mitigation policy and transfer payments. I show that under very general assumptions the business-as-usual outcome is Pareto dominated by such policies and derive the conditions for the set of climate policies that are not dominated thus.

The effects of Gated Communities (GCs) were analysed. According to the literature, these urban artefacts are negative for society. They are blamed to provoking social segregation, social exclusion and undermining democracy. In a Latin American context the consequences could be worse. Latin America has the highest level of social inequality in the world and the rapid growth of GCs is making this inequality more visible. This study implemented the concept of Social Capital, in order to understand the urban problems in this urban geography. The study is based in Machala, a mid-sized city in Ecuador. It was found that GCs’ residents lack of trust of outsiders, residents are more distant from disadvantage groups, social networks are being homogenised and there is a stigmatisation of life outside the community’s walls. This study seeks to create awareness on the type of urban growth in Machala by exploring the consequences of fragmentation, privatisation and segregation via GCs.

Living in poverty and persistent low income has detrimental impacts on many facets of the lives of parents and children. During the early years of the new millennium this was of primary concern to the Scottish and UK governments: in response, policies were implemented to improve children's developmental outcomes, and to increase both maternal employment and levels of income for low paid and unemployed families. Previous qualitative research on families living in poverty revealed that families have varying degrees of additional vulnerability depending on their levels of social assets, e.g. social support, and financial vulnerabilities, e.g. debt and financial stress. High levels of social assets appeared to attenuate, and low levels of social assets appeared to exacerbate, the negative impacts of living in poverty. These social and financial assets/vulnerabilities comprise two of the five domains of the Sustainable Livelihoods Approach (SLA) quantified for use in this thesis. This thesis explores what impacts, if any, social and financial assets/vulnerabilities have on children's cognitive (C) development, as measured by naming vocabulary and picture similarities, and on their social, emotional and behavioural (SEB) development as measured by the Strengths and Difficulties Questionnaire. To achieve this aim this research uses the first five sweeps of the annually-collected longitudinal Growing up in Scotland (GUS) birth cohort study. The analysis uses the technique of factor analysis to derive the latent constructs financial and social assets/vulnerabilities, and OLS multiple regression analysis with quasi-variance to test the associations. The research employs multiple dimensions of economic disadvantage - longitudinal income poverty, material deprivation, longitudinal income poverty and material deprivation combined, and longitudinal income inequality - to explore the effects, not only between the lengths of time people have lived in poverty, but also across the income inequality spectrum, i.e. persistent low income versus persistent high income. The results of the research show that high maternal social assets and financial vulnerabilities separately are associated with higher and lower levels of child SEB development respectively, especially for children living in persistent low income. The relationship did not hold for children’s cognitive development. It also reveals that children whose mothers are experiencing additional financial stress and debt have lower CSEB scores (but not picture similarities), especially in relation to SEB development. There is also a relationship between social and financial assets/vulnerabilities: having high social assets is statistically associated with lower financial stress and debt for those living with lower incomes. This thesis argues that mothers, families and children living in poverty would benefit from policy and practice interventions that support geographical proximity of family and friends, that foster close and supportive wider family relationships, and that promote access to credit that does not lead to unmanageable debt and detrimental levels of additional financial stress. The research notes that while the SLA has been a useful theoretical framework, effectively quantified, the GUS data are limited in how effectively it can construct the SLA as it is not dedicated to its measurement.

This thesis looks at how parental leave and early child care policies in the U.S. can reshape our understanding of the role of government, parental responsibility, and gender within paid labor in order to dismantle the systems of oppression and domination that lead to motherhood inequality. The United States is the only developed economy without mandated paid parental leave, and privatized child care costs can be greater than tuition at public universities. As a result, mothers, still overwhelmingly the primary caregivers in families, are forced to juggle the responsibilities of paid and domestic labor in a way that leads to employment discrimination. Because policies have a unique power to incentivize behavior and change socially ingrained biases, I propose that Congress institute paid parental leave through the FAMILY Act and revives the Comprehensive Child Development Act of 1971 to establish public child care.

Guatemala, the most populous country in Central America, is haunted by the legacy of violence, political instability, poverty, corruption, and persisting, relentless inequality. Narco-trafficking routes through Central America became firmly established after air- and sea-based routes were disrupted by U.S. and Mexican drug enforcement efforts in the 1990s. Guatemala and its Central American neighbors were highly vulnerable to incursion by the drug trade, ideally-located between production sources and major consumers, its people and governments weakened by long-standing armed conflict. Evidence shows the drug trade disproportionately impacts Guatemala in comparison to the rest of the region. Its neighbors share similarly well-located geography and the legacy of armed conflicts, but Guatemala lacks the institutional strength and ability to combat the cartels. This paper posits that U.S. prohibitionist policies are ineffective and harmful to Guatemala’s people, based on a supply-reduction model and a review of previous literature and anecdotal evidence. Narco-trafficking and the United States’ drug enforcement efforts, strategies and policies, intensify existing violence, poverty, inequality and corruption within Guatemala, ensnaring its people in a recurring cycle of violence which reinforces barriers to escaping poverty and crime.
