Improved service delivery through financial management mechanisms: a case of O. R Tambo District Municipality
Get PDFThe study investigated how effective and efficient financial management mechanisms can lead to improved service delivery in the O. R Tambo District Municipality. The study targeted the political leadership, senior and middle management, and key Budget and Treasury Office (BTO) personnel. The non-probability sampling method was used in the study with semi structured interviews conducted on a seventy-one sample size. The results of the interviews were analysed and pointed to the importance of sound financial management systems being critical to enhancing service delivery in the O. R Tambo District. The levels of understanding the role of financial management systems in municipalities differed across levels of authority but there was a general consensus of how effective and efficient financial management mechanisms affect service delivery. In conclusions municipalities need to continuously strive to skill and reskill personnel to maximize on efficiency and improved service delivery.Thesis (MPhil) -- Faculty of Business and Economic Sciences, School of Economics, Development and Tourism, 202
The effectiveness of South African development finance institutions in providing financial and non-financial support to small businesses: the case of Gauteng Enterprise Propeller
Get PDFMany small business owners struggle to keep their businesses operational due to a lack of financial support. It is unclear whether South African development finance institutions (DFIs) are effective in providing such support to small businesses. The primary objective of this study is to investigate how effective South African DFIs are in fostering sustainable growth in small business enterprises through their financial and non-financial support services. The Gauteng Enterprise Propeller (GEP) is used as a case study. This study is located in the positivistic research tradition and therefore followed a quantitative research approach. Closed-ended questionnaires were distributed to 150 small businesses who were funded by the GEP. Self-constructed instruments were used to measure the independent variables and the dependent variable of the study. Multiple regression analysis was conducted to investigate the hypothesised relationships. Empirical results were that the participants largely disagreed (average mean score of less than two on a five-point scale) that the GEP frequently provides financial and non-financial support to small businesses. The results also demonstrate that the GEP’s marketing material, planning support, financial management and asset acquisition interventions were significantly related to the perceived business success of the sampled small businesses, while operational support interventions were not significantly related. On both a theoretical and practical level, the study adds to the knowledge of which financial and non-financial support interventions play a significant role in the success of small businesses. With the contribution of this study, South African DFIs can improve their financial and non-financial support strategies to assist small businesses in growing their operations. The study also provides a practical assessment of how GEP support recipients experience such support.Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 202
Gamification Recommendations to address the user experience of the security education and training course at the Nelson Mandela University
Get PDFThe use of technology alone cannot ensure a secure environment for organisations. Consideration should be given to the human aspect of cybersecurity. User errors are rooted in a lack of awareness and ignorance. A security awareness programme allows organisations to equip employees with the knowledge required to safeguard their data. The Security Education and Training (SEAT) course provided at the Nelson Mandela University seeks to bridge the gap by providing the necessary tools to equip students to be better employees for their future employers. However, the SEAT course is fairly outdated and has a poor user experience. Gamification has therefore been considered to address the user experience of the SEAT course. Incorporating game elements can help to increase the positive user experience of a system. User experience designers use gamification and well-chosen game elements to improve user experience. People enjoy using systems that are full of excitement, and that challenge and encourage a competitive spirit. The primary objective of this study is to provide recommendations for the gamification of the user experience of the SEAT course at the Nelson Mandela University. The primary objective is further divided into several secondary objectives that aim to address the proposed problem. The secondary objectives are to investigate user experience, identifying the most common user experience evaluation methods; to understand gamification and to identify relevant game elements that could enhance the user experience of the SEAT course at the Nelson Mandela University; to evaluate the user experience of the Nelson Mandela University SEAT course and to identify opportunities to implement the identified game elements; to implement the identified game elements into the selected module of the SEAT course. A literature review was conducted to gather an understanding of user experience, user experience evaluation methods, gamification, and game elements. A prototype was created using the information gathered in the literature review, based on a component of the SEAT course. The prototype incorporates different game elements that foster motivation in users. The prototype is used as a proof-of-concept, demonstrating that gamification can address the user experience of the SEAT course. Self-evaluations were conducted on both the SEAT course and the prototype, as a first step in comparing the user experience of the original SEAT course with the proof-of-concept prototype. Finally, gamification recommendations were proposed to address the user experience of the SEAT course.Thesis (MIT) -- Faculty of Engineering, the Built Environment and Information Technology, School of Information Techonology, 202
Historical diversification of Pseudonympha Wallengren, 1857 (Lepidoptera: Nymphalidae: Satyrinae).
No full textThe butterfly genus Pseudonympha and several related genera are endemic to southern Africa. Although many of the species are montane, some inhabit the arid interior of South Africa, offering an opportunity to study the palaeobiogeography of this biome. Morphological data (for all species of Pseudonympha and allied African and Asian genera) and molecular data (WG and COI genes for nine of the 15 species of Pseudonympha and all of the southern African endemic genera of Ypthimina) were compiled. Phylogenetic analysis indicated that Pseudonympha apparently originated in the Cape Fold Mountains about 15 Mya ago and spread steadily eastwards and northwards along the Great Escarpment during the aridification of the region, perhaps assisted by orogeny in the east and oceanic cooling in the west. Aridification cycles seem to have intermittently isolated some early lineages in elevated habitats in the interior, so that those lineages show lower speciation rates (or perhaps higher extinction rates) than those in the east. Four species delineation techniques indicated that some species are taxonomically oversplit. Based on genetic polyphyly and morphological similarity, we propose that the status of P. swanepoeli be reduced to that of a subspecies of P. varii, such that all the north-eastern populations from Harrismith to Tzaneen fall under P. varii swanepoeli van Son stat. n., and all the southern populations fall under P. varii varii van Son stat. n. Ultimately, the diversification of both of these lineages seems tied to their host plants’ response to aridification brought on by continental drift and orogeny. Sympatric organisms (eg cicadas) with biologies focused around different resources (eg savanna trees) show other patterns of diversification. The phylogenetic analysis of the subtribe Ypthimina also supports the monophyly of Paternympha, paraphyly of Ypthima, recognition of Thymipa Moore stat. rev. as a phylogenetic independent genus, and new relationships for Strabena
The posttraumatic growth of Natalie Du Toit: A psychobiography
Get PDFThis study sought to gain insight into the phenomenon of posttraumatic growth by performing a psychobiography of Natalie du Toit, who underwent a traumatic experience and acquired a disability. This study employed a psychobiographical methodology in order to interpret the life of Paralympic gold medallist, Natalie du Toit, from a psychosocial development perspective. The study used a qualitative research paradigm and a purposive sampling technique was employed to select Natalie du Toit. This was done to determine the extent to which Natalie du Toit underwent developmental growth as a result of posttraumatic growth after recuperating from her trauma. Tedeschi and Calhoun’s Posttraumatic Growth Model was used to inform the research. This model was used to describe the life experiences and events that characterised the posttraumatic adjustment of Natalie du Toit and interpret these through Tedeschi and Calhoun’s Posttraumatic Growth Model. The findings revealed a significant extend the existence of all five variables of Tedeschi and Calhoun’s Posttraumatic Growth Model, in the life of Natalie du Toit.Thesis (MA) -- Faculty of Business and Economic Sciences, 202
The quantification of Pinus patula recovery and productivity of manually orientated biomass collection in post mechanised full tree and semi mechanised tree length harvesting operations
Get PDFThe use of biomass as an alternate source of energy has grown in popularity. Different types of biomass are obtained from a variety of sources including natural forests, forestry plantations and agriculture residues. However, forestry residues have been identified as the most promising source, due to the wide variety of plant products including leaves, twigs, branches, merchantable stem, stumps and roots. The main sources of plantation forest biomass are residues from thinning, clearfell and conventional products such as pulpwood and sawn timber operations. These residues can accumulate between 4.3 to 9.4 billion tonnes annually around the world. The biomass availability in plantation forests has led to the development of different harvesting systems to help collect the products from infield to sawmill. Biomass harvesting has mainly been achieved through mechanised systems because of their high yields. However, the use of manual systems has been neglected due to technical limitations and financial viability. Thus, in South Africa, there is no scientific research looking at manual systems of collecting biomass from plantations. Because of this, different forestry stakeholders, including small growers and contractors using manual systems for biomass harvesting have limited knowledge regarding what to expect in terms of recoverable amounts, productivity and cost. This research examines the productivity of the manual biomass collection and the quantification of recovered and unrecovered residues after mechanised full tree (FT) and semi mechanised tree length (TL) harvesting operations in Pinus patula compartments. A total number of 8 plots with +/-200 standing trees were marked in each system. The diameter and height of all marked trees were measured to determine tree volume. Moreover, the quantification of recoverable woody biomass was determined, where after, a residues assessment method using plots and line transects was used to determine the amount of unrecovered residues.Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 202
Modelling the dynamics of Breast Cancer disease with hormone therapy and surgery controls
Get PDFIn this study, we discussed a mathematical model that incorporates important interactions between normal cells, tumor cells, immune cells, and estrogen. The mathematical model was revised to include two control measures; namely surgery and hormone therapy to minimize the number of tumor cells. The model was mathematically analyzed with the premise that the two control measures are positive constants. Locally and globally analyses were performed using a variety of analytical methods to investigate the stability of the breast cancer model. Furthermore, an optimal control problem was formulated and used to determine the best strategy for reducing the number of tumor cells by incorporating hormone therapy and surgery, based on the well-known Pontryagin’s Maximum Principle. The numerical results indicates combining both optimal control measures (surgery and hormone therapy) simultaneously is more efficacious than using single control measure separately in decreasing the number of tumor cells.Thesis (MSc) -- Faculty of Science, School of Computer Science, Mathematics, Physics and Statistics, 202
Technology acceptance model perceptions of operational staff on the implementation of advanced radiography equipment
Get PDFThroughout the recent history of South Africa, the increasing requirements from state and private sector healthcare institutions have relied heavily upon medical imaging technologies for the purposes of improved patient healthcare and service quality standards. Developments in this field of healthcare have seen many interesting and challenging operational changes: from the first implementation and use of X-ray equipment demonstrated in Krugersdorp in 1899; to the current advanced digital systems found in the medical imaging services sector of healthcare. This research study measured the medical imaging operational staff perceptions about new advanced medical imaging equipment and technologies. The theory crossed the academic disciplines through a quantitative survey about technology, operations management and healthcare. Together with staff perceptions about future medical imaging technologies’ usefulness and ease of use, the findings may impact their daily operations within a conducive technology acceptance management paradigm.Thesis (MA) -- Faculty of Faculty of Business and Economic Sciences, 202
South African traditional healers’ perceptions and treatment of the symptoms of depression
Get PDFWhile depression is experienced worldwide, the World Health Organization indicated that over 80% of this disease burden is found in low- and middle-income countries, with 16% of depressive disorder cases being found in Africa. Specifically, in South Africa, the lifetime prevalence of major depressive disorder is 9.7%. Research conducted on traditional healing estimates that as high as 80% of black individuals in South Africa choose to consult traditional healers. Although there was initial consensus that the use of traditional healers reflected a lack of access to alternative resources, more recent research has however indicated that traditional healers are consulted even when psychiatric facilities and medication are available. Research has illustrated that many patients that chose to consult traditional healers do so as a result of their shared beliefs, and traditional healers' ability to understand the cultural frameworks underlying illness. The current study investigated how traditional healers in the Eastern Cape perceive and treat phenomena currently understood as the symptoms of depression and how these understandings can be incorporated into collaborations between Western medicine and traditional healing practice. A qualitative research design was used to examine the perspectives and treatment methods of isiXhosa traditional healers in the Eastern Cape. Four healers participated in the study. Key findings indicated that there is no single cause or definition of the phenomenon of depression by healers. Causality is greatly attributed to spiritual causes and ancestors play a key role in guiding the diagnosis and multiple treatment interventions employed by healers to treat the experience of depression. Finally, all traditional healers expressed a willingness to collaborate and work with the Western healthcare system, however, they indicated a strong need for greater recognition as a valid healthcare system.Thesis (MA) -- Faculty of Humanities, Psychology, 202
Challenges and opportunities of coastal and marine tourism in Swartkops river Estuary
Get PDFThis study's goal was to pinpoint the challenges and untapped opportunities associated with Coastal and Marine Tourism (CMT) in the Swartkops River Estuary (SRE). CMT has become the biggest segment of the travel industry. Moreover, this form of alternative tourism is the most significant and fastest developing economic activity in the ocean. The objectives of this study were to identify the challenges that hinder the development of CMT in SRE, to determine opportunities for CMT in SRE, to evaluate NMBM’s efforts in creating and sustaining CMT in SRE and to evaluate the status of CMT in SRE in terms of CMT related development. This study fit within the interprevist paradigm and made use of a qualitative research approach and design as well as inductive reasoning. The qualitative research design consisted of data being collected through document and content analysis. Data was analysed using data analysis process of Miles and Herman (1994) as well as the coding and developing of specific themes that emerged from the data. The data in this phase was presented both in narrative format and tables. The document analysis used in this study was established based on the objectives of this study. The findings of this study revealed that key challenges that hinder the growth of CMT in Swartkops River Estuary are environmental impacts that include pollution, over enrichment, inappropriate development, overfishing, destruction of mudflats, limited freshwater inflow, destruction of vegetation and climate change. The findings also revealed that there are opportunities for CMT in SRE such as promoting SRE as a popular ecotourism destination by developing ecotourism nodes. These include environmental education at the Aloes Nature Reserve's and the Swartkops Estuary south-east section, sustainable ecolodges and conference centres. The study recommends that the Nelson Mandela Bay Municipality should organize educational programmes to educate local people about the significance of conserving and safeguarding the environment for future generations. These findings also posed certain challenges linked to those identified in the analysis.Thesis (MPhil) -- Faculty of Business and Economic Sciences, School of Economics, Development & Tourism, 202
