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
The assessment of public participation as a model to enhance development in local government: the case of Raymond Mhlaba local municipality in the Eastern Cape
Get PDFThe notion of public participation in decision-making processes is one of the mechanisms that seek to entrench equality and transform social coherence between government and citizens. This view relates to the provision of quality and sustainability of goods and services. The individuals, both in their capacity as citizens and consumers of public goods and services should be allowed to participate in the development that affect in terms of the regulatory frameworks. They should be permitted and encouraged to express their views on governance and development matters pertaining to them. Nevertheless, there are number of factors that impede the participation of the local communities in development planning processes, such as a communication gap between government officials and communities, socio-economic inequalities, poor service delivery, unemployment, a lack of capacity building and transparency to mention a few. The planning and implementation of municipal projects should be accepted only after considerable discussion and consultation with communities. This process is seen as allowing deprived groups and individuals to have voices in future development initiatives. As such, public participation enables for full involvement of ordinary members of the community in decision making, planning, designing, organising and executing development initiatives that affect them. The Researcher decided to embark on a study entitled: The assessment of public participation as a model to enhance development in local government. The case of Raymond Mhlaba Local Municipality in the Eastern Cape. Adopting the quantitative research design, data was collected through questionnaires for the key informants consisting of 3 participants, 3 officials from Raymond Mhlaba Municipality. Data was also collected through in-depth semi-structured interviews with members of the communities from Kataga in Adelaide, Gaga Village in Alice and Magaleni location in Fort Beaufort. Eighteen (18) community members were selected to participate in the study from both communities inclusive of ward councillors. Community members were organised into 1 focus group participants in each location (comprising of 6 people per group).To support the data obtained from focus group 3 key informants from Raymond Mhlaba Municipality participated in the investigation. A heterogeneous population of 21 respondents participated in this study. The thematic analysis was vii used to analyse data. The findings consistently show that the ability of a local government to work effectively dependent on inclusive planning, implementation and decision making processes. This means that local government development is also required for the impartial and efficient operation of public institutions. Public confidence in local municipalities is expressed as one of the main factors that determine the government‘s competitiveness.Thesis (MA) -- Faculty of Faculty of Business and Economic Sciences, 202
Community participation in selected public schools of Komani, Eastern Cape
Get PDFThis study is located in Mlungisi Township of Komani in the Eastern Cape - where the aim was to closely examine the role played by this community to build and govern its public schools. The study selected the three biggest schools in the area to examine how the community’s involvement in them has surfaced from their founding up to the present times. The study found that through these three schools, this community managed, under apartheid, to take initiative by mobilising itself for self-development by building these schools and infusing them with a liberation curriculum that was required for the conditions of oppression and resistance at the time. This community in essence turned the intentions of Bantu education around by using these schools as sites of alternative education that was delivered by its own activist teachers to conscientise the student youth about community struggles. Black people in this community used these schools as emancipatory spaces to connect student struggles with community struggles to build community power. In the post-apartheid epoch, much of these traditions and levels of community participation have dropped because of new precarious economies and labour conditions that keep the adult population busy. As a result, present-day community participation is not as politically intentional as it was under apartheid. Theoretically, the study applied Paulo Freire’s Critical Community Pedagogy. Methodologically, the study utilised critical qualitative oral histories and semi-structured interviews.Thesis (MA) -- Faculty of Humanities, School of Governmental and Social Sciences, 202
The use of Police force in crowd management
Get PDFSouth Africa has a violent and oppressive past. They are various historical incidents1 of extreme cruelty perpetrated by the previous apartheid regime. Much of the modern South African democratic state was forged by protests. During the 1970s and 80s, the legislator by passing unjust laws was used to assist the government to maintain the oppression of the people of South Africa. From the Soweto uprising in the 1970s to the current service delivery protests of the 21st century, gatherings have always had the potential for deadly violence. The motivation for this research started with the emotions evoked by the iconic picture of the body of Hector Pietersen2 being carried after being shot by the police. Strikingly the images of the killing by the police of Andries Tatane conjured further questions concerning the use of deadly force within crowd management situations. The research undertook an analysis of the use of force by the police during crowd management situations. A brief analysis of South African law relating to the use of force by the police prior to 1996 is provided. There are legislative prescripts for the use of force during the maintenance of public order. It must be noted that the legislation falls short on providing clear, concise authority for the use of deadly force. Normally, the use of force by the police and civilians for the purpose of arrest is regulated by the Criminal Procedure Act3 , whereas the Regulation of Gatherings Act4 providing the authority for the use of force by the police in crowd management situations to preserve public order. At first glance, section 49 of the CPA seems to validate arguments that it violates some constitutionally protected rights, among which are the right to dignity, life, to freedom and security of the person, against cruel, inhuman or degrading treatment or punishment and to a fair trial, which includes the right to be presumed innocent. Section 49 however, withstood Constitutional muster as set out in Re: S v Walters & another. As the right to life is a non derogable right.5 The limitation of this right may lead to constitutional scrutiny. The emphasis will thus be on ensuring that the balance with regards to proportionality in the use of deadly force is maintained. During the research it became apparent that the police, especially during crowd management situations, served political interests.6 This had the unintended consequence that the laws were applied to suit the political narrative and not the rule of law. The use of force in the policing arena is controversial. It is very clear that any misuse of force in crowd management situations will evoke the historical wounds associated with apartheid. However, within crowd management, the use of force and the authority to use deadly force is absolutely necessary. The Marikana massacre was used to highlight the mistakes that police have made during inappropriate use of force and its catastrophic consequences.7 It was observed that the legislative framework concerning the use of force, whether under section 49 of the CPA or section 9 of the RGA, is incoherent and too complex. The research argues for simplicity and accuracy within policy and applicable legislative alignment. The linkages from the applicable legislation to the institutional policies should never be outdated or incorrectly formulated. The violent rhetoric from politicians such as ex-president Jacob Zuma, 8 Minister Fikile Mbalula 9 and Bheki Cele10 fuels the argument that the police are susceptible to misdirected notions and may cause the police act unlawfully. The Constitution requires the police to “enforce the law”11 and as such there is an obligation on the police to do this within the constitutional parameters. The correct use of deadly force will only be achieved if the SAPS adequately resource, train and regularly refresh their members regarding the use of force when policing protests.Thesis (LLM -- Faculty of Law, School of Criminal and Procedural Law, 202
Unit managers’ perceptions of compassion fatigue among nurses at private hospitals in the Eastern Cape
Get PDFCaring has been described in literature as encompassing empathy, attentiveness, experience, and sensitivity, which is then translated into nursing bedside practice. However, the cost of caring may cause nurses to become withdrawn and unable to care for their patients. This phenomenon is called compassion fatigue (CF), where nurses feel unable to respond to their patients and become withdrawn from stressful scenarios in the unit. CF is prevalent globally among nurses based in all hospital disciplines. The aim of the study is to explore unit managers’ perceptions of CF among nurses in private hospitals in the Eastern Cape in order to develop recommendations for UMs on how to respond to CF among nursing staff. The study used a qualitative, exploratory-descriptive approach. The researcher used Williams, McDowell and Kautz’s (2011) Caring Leadership Model to explore the UMs’ perceptions of CF. The population chosen for this study was the UMs in private hospitals in the Eastern Cape. A minimum of 12 UMs were purposively sampled to take part in the study. Data was collected by means of semi-structured individual interviews. Lincoln and Guba’s four criteria of trustworthiness, namely: credibility, conformability, dependability and transferability were applied to enhance the quality of the study. The researcher upheld the ethical standards of the Belmont Report throughout the course of the study. Five themes were identified using Braun and Clarke’s data analysis method. The themes identified were: Theme 1: UMs’ perceptions of the manifestations of CF among their nursing staff; Theme 2: UMs’ perceptions of contributors to CF among their nursing staff; Theme 3: UMs identified that patient outcomes may have been hindered by CF among their nursing staff; Theme 4: UMs sought to enhance the well-being of their nursing staff which may have mitigated possible CF; Theme 5: Suggestions by UMs regarding UM self-awareness and improved support for each other. Hence the complex phenomenon of CF was explored through the UMs’ descriptions of their perceptions as leaders of nurses in the nursing practice setting. The UMs shared the difficulty of their roles, most especially related to how they struggled to vi support their staff while at the same time, feeling unsupported themselves. UMs were struggling, with staff who appeared to have CF. UMs reported that staff seemed more irritable, and angry. Added to these changes in behaviour, were signs that staff were not coping with the workload as well as with very ill patients. These changes in behaviour, signs of emotional and physical fatigue as well as higher rates of absenteeism all seemed to be aligned with the classical signs and symptoms of CF as described in much of the literature. Once the themes had been identified, a modified version of the AGREE II tool was used as a framework to develop the following recommendations: Recommendation 1: Facilitate UM peer support regarding CF management; Recommendation 2: Train UMs regarding CF and related conditions; Recommendation 3: Assist UMs to support their staff who are exhibiting CF.Thesis (MCur) -- Faculty of Health Sciences, School of Clinical Care & Medicinal Sciences, 202
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
An efficient approach for the synthesis of dolutegravir and its analogue exploiting flow chemistry
Get PDFAfrica has the highest Human Immunodeficiency Virus (HIV) prevalence in the world and has invested heavily in running its HIV programmes and conducting research of medical significance. Despite efforts in combating this disease the production, distribution, cost, and availability of antiretroviral (ARV) generics remains a major problem as they are imported from China and India. Exploring the recently emerged “enabling technique”, namely flow chemistry in the production of APIs has gained a lot of attention. This study was devoted on exploring the application of flow chemistry on the synthesis of a newly approved anti-HIV drug dolutegravir (DTG); an integrase inhibitor with a high genetic barrier to resistance with a daily dosing scheduled compared to other ARVs and its third-generation inhibitor analogue, cabotegravir. Chapter one covers a comprehensive background and literature review of the HIV epidemic, an introduction of antiretroviral therapy as well as detailed dolutegravir and cabotegravir synthesis. A brief introduction of continuous flow technology with its advantages and disadvantages is discussed in this chapter. The efficient seven-step continuous flow procedure afforded dolutegravir and cabotegravir in improved reaction times and yields compared to the traditional batch procedure was demonstrated. The significant advantage of this flow process includes the reduction of the overall reaction time from step one to step seven, from prolonged 68 hours in batch to 34 minutes. The overall yield of each reaction step improved dramatically upon flow optimization. The yields of the second step (selective ester hydrolysis), fourth step (cyclization) and fifth step (amidation) increased from 64 %, 40 % and 33 % in batch to 98 %, 71 % and 100 % yield by HPLC respectively. Other than improved yields and residence times which was aided advantages of microreactor technology including intensive mixing, the flow process is also much better because it is cost effective. Most importantly, a novel process on the formation of pyridinone intermediate using ion-exchange resin catalysts towards the synthesis of dolutegravir and cabotegravir was described in this studyThesis (PhD) -- Faculty of Science, School of Biomolecular and Chemical Science, 202

How procurement industry trends can lessen the impact of procurement delays at Eastern Cape Department of Health (ECDOH)
Get PDFThis research study came about as a result of healthcare failures and underperformance at the Eastern Cape Department of Health, causing procurement delays. Procurement is central to the government service delivery system as it promotes goals that are secondary to the primary aim of procurement, such as using procurement to promote social, industrial, or environmental policies. The ultimate goal of the study was to research the root cause for procurement delays and how improvements can be brought about through studying procurement industry trends. The critical step to resolve bottlenecks in the procurement system is to investigate the root cause. Six causes of procurement delays emerged from the literature due to: (1) procurement staff, (2) procurement irregularities, (3) poor budget planning and demand forecasting, (4) poor communication, (5) procurement structure, and, (6) manual systems used for procurement transactions. Guided by these causes of procurement delays, the researcher developed a questionnaire to understand the cause of delays at the Eastern Cape Department of Health. An interpretivism research paradigm (quantitative) was selected to analyze research on best practices. The researcher distributed questionnaires as a method for collecting data from the identified sample size of 90. The purpose of the questionnaire was to validate the data collected during the literature review. Out of the distributed sample, 69 responses were received and used for analysis, thus representing a 74% response rate, which is considered acceptable. The researcher used descriptive analysis to interpret data. The study's key findings indicated that ECDOH employees had been fairly trained on the SCM policies within the department. However, there is a concerning representation of 40,6% of employees who have not been provided with training, which could impact responsiveness to the procurement process. The study further revealed that 85,5% of employees understood the impact of procurement delays due to irregular expenditure (an Auditor General repeat finding for the ECDOH).Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 202
The factors affecting the effectiveness of asset management in the COCT municipality's urban waste management directorate
Get PDFThis study aims to investigate how Internal control system (ICS), Information system (IFS), Employee competence (ECT) and Leadership commitment (LDC) influence the effectiveness of asset management in the City of Cape Town municipality’s Urban Waste Management directorate. A quantitative research approach was employed to investigate these four factors. Primary data was collected from 114 respondents, using online questionnaires that were administered through QuestionPro; the completed questionnaires were then analyzed using Statistica Data Science Workbench, version 14. Results showed that all four factors – Employee Competence, Internal Control System, Information System and Leadership Commitment – have a positive and significant impact on the effectiveness of asset management. The findings and recommendations of this study are expected to provide practical information as well as a reference for municipalities, so as to help them improve their fixed asset management.Thesis (MBA) -- Faculty of Business and Economic Sciences, Business School, 202
