- Description: The purpose of this study was to investigate the factors that affect understanding of business strategy at different levels of the organisation. The investigation was done by looking at relationship between the business strategy (as a dependant variable) and the organisational structure, the employee level or position, skills, experience and education (as independent variables). These factors were investigated through the analysis of literature and empirical study. The results of this analysis were recorded through the last two chapters (chapter four and five). As in most organisations, there is sometimes different interpretations of business strategy by employees at different levels (or sometimes across) of the organisational structure. This study does not just seek to add value in the literature but also to equip managers tasked with enrolling out business strategies. The basis of the study emanates from corporate failures associated with the business strategies and the failure of implementation and this is discussed further in chapter one with reference to specific sources. The empirical study that was conducted attracted a good response, as there was more than 100 percent response rate, through the use of latest technology and social media. The main conclusions, managerial implications and theoretical framework that came through from the study, are clearly stated in the last chapter, chapter five and can help managers that formulate or implement to business strategies, to ensure that there is great understanding within their workplaces. , Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 2022

- Description: Estuaries occur at the interface between the terrestrial and marine environment and as such act as the last ‘filtering’ mechanism prior to nutrient pollution entering the adjacent ocean. This study focused on the Swartkops Estuary which is eutrophic and requires the removal of nutrients. The role of phytoplankton as nutrient filters and storage of nutrients by seagrass and salt marsh was investigated. This study found that phytoplankton temporarily took up a large percentage of dissolved inorganic nitrogen (max. 99%) and dissolved silica (max. 76%) and limited amounts of dissolved inorganic phosphorus (max. 18%). The amount of carbon, nitrogen and phosphorus stored by the salt marsh species Spartina maritima and Salicornia tegetaria and the seagrass species Zostera capensis were determined. It was found that the salt marsh grass Spartina maritima stored the most nutrients (149.61 ± 16.59 N g m-2 ; 105.44 ± 13.41 P g m-2 ; 1690.52 ± 168.90 C g m-2 ), while for the salt marsh succulent Salicornia tegetaria less nutrients were stored (27.01 ± 4.17 N g m-2 ; 22.97 ± 3.21 P g m-2 ; 458.66 ± 69.43 C g m-2 ). Zostera capensis also acted as a nutrient store (22.17 ± 6.94 N g m-2 ; 23.75 ± 4.70 P g m-2 ; 221.10 ± 26.74 C g m-2 ). The macrophytes were able to store nutrients for longer periods and thus prevent these nutrients from being exported into the adjacent ocean. On the contrary, phytoplankton uptake was temporary as the nutrients are released once the bloom decays. Without intervention there will be an increase of harmful algal blooms (HABs) and fish kills in the eutrophic Swartkops Estuary. Nutrient input from upstream wastewater treatment works, canals and stormwater run-off must be reduced. Conservation and management of the seagrass and salt marsh habitats is needed to ensure the long-term storage of nutrients , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: The year 1994 marked the dawn of the new, democratic South Africa. It also brought its own sets of challenges to the country. One such challenge was urban space. Regrettably, the new dispensation inherited still very much race-based urban areas. Urban space is understood to be a social outcome, the result of an historical process, an unequal accumulation of time, a presupposition, and a milieu of social production (Balbim, 2016). The distinguishing feature of urban space in South Africa is the phenomenon of exclusion, which causes deformity, and disappearance of urban structure. Exclusion has become a permanent visual reality in cities in which walled and gated communities divide the urban tissue and take up a large part of the urban space. The social action and struggle against the exclusionary process of globalisation such as the commodification and privatisation of urban space have always been on the international urban agenda. The study’s literature review suggests that government attitudes towards human settlements should change, particularly in terms of policymaking to combat the contemporary urban disparities such as fragmentation (also known as “enclave urbanism”). Fragmented cities do not function as a system but more and more as juxtaposed and uncoordinated fragments drifting apart (Bénit-Gbaffou, 2008). This has an immense impact on several sustainability influencing variables. Urban fragmentation can also have profound effects on human social dynamics and well-being by reducing the number of green spaces in cities. As loss of biodiversity continues, total core area and habitat cohesion decrease while edge density and shape complexity increase. Cities are required to be more sustainable, more accessible, and equal. Cities are now witnessing the emergence of real estate products that are far from achieving the previously mentioned goals, particularly inclusivity. Inclusivity in cities can be achieved by a contemporary urban development approach referred to as ‘inclusive urban space production’. Inclusive urban space production is a pro-poor approach that equally values and incorporates the contributions of all city stakeholders in addressing development issues, including the marginalised groups. The aim of this inquiry was, therefore, to examine factors that influence urban space production to generate a responsive urban space production model, referred to in this study as the “IUSP model”. The study also aimed at examining the role of the state and xx other stakeholders involved in the production of urban space, including the private sector and the community. Participation by all of them is essential to enhance inclusive urban space production for sustainability. A theoretical model for inclusive urban space production was developed based on an intensive literature review. Also, a concurrent partially mixed method design was employed in this inquiry. A study of Waterfall City was conducted to understand exclusive developments and their effect on the larger urban system. And a survey questionnaire was disseminated using random sampling. This was to measure the postulated model. Results from these two concurrent approaches were merged to yield the final model. The findings from the case study were analysed using ATLAS.ti and the findings from the survey questionnaire were analysed using several analyses techniques including EFA, correlation and regression. Both sets of results indicated that the intention to promote inclusive developments is predicted by seventeen dependent variables categorically presented under urban development characteristics, exclusive development enablers, inclusive development barriers, and sustainability criteria. The results of this inquiry are significant because they bring together the interdisciplinary perspectives to discern comprehensively the idea of inclusivity and sustainability in urban space production. The responsive model developed as a key product of this study aims to assist policymakers, planners, designers, landscapers, and developers as a guideline for facilitating inclusive and sustainable urban development. , Thesis (PhD) -- Faculty of Engineering, the Built Environment, and Technology, 2022

- Description: Over the last decade, a bold move has been made by researchers to shift focus on improving and establishing accurate and reliable measures of economic activity across the globe. With an everchanging global economic landscape, unreliable GDP statistics and the lack thereof have held a nascent impact on formulating appropriate stabilization policies. This, in turn, have affected the affairs of nations, especially low income and developing ones. In an attempt to find alternative ways to measure economic activity, night time lights data have emerged in numerous empirical studies as a novel way of attempting to measure economic growth and development. Various studies have found this to be useful for countries that do not have statistical capabilities such as poor nations, while other studies have put forward arguments in favour of a possible non-linear relationship between GDP and night time lights data. Against this background, this study implores night time lights data extensively to establish whether it can serve as a possible measure of GDP in Sub-Saharan Africa between 1992 and 2012. Based on the results obtained from testing for a positive correlation between GDP and night time lights data in Sub-Saharan Africa, the study further aim to use night time lights data as a measure of GDP in the regressions against proxies of well-being, urbanization, and environmental degradation. The significance of the study relates to the fact that the estimation accuracy of GDP is positively influenced by spatial and radiation resolution of night time lights data. In addition, by taking a country-specific approach using more advanced econometric estimation techniques, this study improves on the empirical literature pertaining to African countries. All facets of pooled ordinary least squares (POLS), the pooled mean group estimators, as well as the wavelet coherence estimation techniques were the three approaches used to investigated correlations between night time lights data and economic activity. Overall findings indicate little evidence that night time lights data derived from the DMSP-OLS archive can serve as a strong measure of GDP in regressions across the Sub-Saharan African region. Recommendations and avenues for future research are outlined at the end of the study. , Thesis (PhD) -- Faculty of Business and Economics Science, School of Applied Accounting, 2022

- Description: Lions are apex predators that play a vital role in the ecosystem. They regulate prey species through predation and other non-consumptive means. Factors that have influenced the decline of lion populations across Africa in the last half century, are loss of habitat, human wildlife conflict and the depletion of prey species. Extensive reintroductions of lions have been conducted across South Africa in order to restore their numbers in protected areas. The Pilanesberg National Park (PNP) was one of many protected areas that reintroduced lions. Their numbers were well documented by management until 2005 where they lost track of the population numbers. During this unfortunate period, there was an observed decline in prey numbers. The aim of this dissertation was to estimate the abundance, movement, and sex ratio of lions, in PNP. Abundance, movement, and sex ratio were determined by a three-month intensive lion survey. The location of each lion encounter was recorded on a mobile device which had an application installed called Cybertracker (v3). Photographs were taken of each Lion to build identification kits. For the data analysis, I used the Bayesian spatial explicit capture-recapture (SECR) model. This model takes time, space, and the robustness of an individual lion into account. Robustness is the measure of how well a lion maintains their functionality, when various stressors are applied (Harmsen, Foster, & Quigley, 2020). The estimated lion population in PNP was 44 lions (>1 year) with a density of 8.8 lions per 100 km2 . The estimated mean home range size of male lions was 279 km2 with a highest probability density (HPD) range of 179 – 385 km2 . The estimated mean home range of female lions was 191 km2 with a HPD range of 135 – 262 km2 . The larger home range size for male lions and smaller home range size for females is found v throughout the African continent in protected areas. The estimated sex ratio was 0.9♀:1♂, which is unexpected as PNP sex ratios between male and female lions is usually 2♀:1♂. A future sampling design for PNP was produced from the completed lion survey dataset. I drove a total of 7350 km and evaluated the influence of varied sampling efforts (i.e., kms driven) on precision estimates and relative bias for abundance, movement, and sex ratio. I found that a minimum of 4 000 km was needed to adequately estimate the lion abundance, movement, and sex ratio in this small fenced protected area. These findings can be used to help guide management to the most cost-effective sampling method and still obtain accurate estimates for monitoring lions. By showing management what is required for appropriate lion surveys this might help improve future monitoring. , Thesis (MSc) -- Faculty of Science, School of Natural Resource Management, 2022
