- Description: With the world’s growing population and limited natural resources, there is a need to produce more food using less inputs. A major limiting factor to meeting the agricultural production needs of the growing population is fresh water. Water is a critical resource in agriculture and may be more of a limiting factor than other crop growth requirements in some areas. Furthermore, water availability is being impacted by climate change and competition from other industries. Methods of improving crop water use efficiency through conservation of water and the enhancement of crop growth need to be employed to meet the growing demand sustainably. The purpose of the research was to assess the differences in soil water status between organically farmed crops with a grass mulch and conventionally farmed crops without mulch, with a view to making more efficient use of the water resource. This research was conducted at the Mandela long term organic farming systems research trial site at Nelson Mandela University, George campus in the southern Cape, South Africa. It is part of a larger research project (the Mandela Trials) in which various researchers have been involved in different aspects of this trial including agronomy, microbiology and pest and disease control. This research took place over two seasons, namely, 2016-2017 season and 2017-2018 season. The soil water content (SWC) of organic and conventional plots were measured using fixed capacitance probes that recorded continuous data, every half hour, at depths of 10, 30 and 50 cm. A handheld theta probe was also used to measure the SWC in the top 6 cm of the soil at 7 to14 day intervals. The organic treatment had a significantly higher SWC than the conventional treatment over the two seasons in which this research was conducted. In addition, soil carbon was significantly higher in the organic treatment, than the conventional. Organic farming methods preserve and promote an increase in soil organic matter, thus improving the soil structure and increasing the soil’s water holding capacity. From this research, it is concluded that organic farming practices can be used to help conserve SWC, keeping it available to crops for longer and helping farmers make more efficient use of this scarce resource. This is especially relevant for low rainfall areas which are affected by water shortages. The improved SWC availability should be coupled with good agronomic practices to increase productive water losses and the conversion of water to yields, thus increasing water use efficiency. In addition, adding organic matter to the soil will improve resilience of the soil and help sequester carbon and thus help in mitigating climate change.

- Description: Salt marshes are one of the most productive ecosystems globally. These ‘blue carbon’ habitats are in many respects resilient to climate change effects, able to track sea level rise and act as carbon sinks. Since salt marshes are economically and ecologically essential habitats (for example providing foraging grounds for invertebrates, fish, birds and humans), understanding the processes that control their structure is crucial to best maintain ecosystem services provided by these habitats. For decades the importance of top-down forces, such as grazing, has not been recognised as being important in controlling salt marsh plant productivity. Rather, bottom-up forces, such as the availability of oxygen, was thought to be the main constraint to primary production. Therefore, a better understanding of salt marsh ecosystem dynamics and whether grazer control exists is needed. Although grazer top-down control has been demonstrated in salt marshes in locations such as the United States, this has not been investigated in South Africa. This is a crucial knowledge gap locally considering the importance of salt marsh ecosystems. The aim of this study was therefore to determine what role consumers play in structuring South Africa’s estuarine salt marsh vegetation, thereby also contextualising this process internationally. In order to achieve this, the abundance of grapsoid crabs was estimated and related to key salt marsh features, such as Spartina maritima stem height and stem density, which was quantified from observational surveys. Sampling took place at the beginning and end of the early-spring and late-summer growth period (September 2021 and April 2022) in the Knysna, Kromme and Swartkops estuaries. If a correlation was observed between crab density and salt marsh features, it was important to determine whether they consume the salt marsh vegetation or if the effect was due to their burrowing activities. Hence, the diet of grapsoid crabs was investigated using stable isotope and gut content analysis. To examine the importance of crab grazing in controlling the growth of salt marsh vegetation, crab abundance was manipulated in situ by means of exclusion cages. This experiment ran for five months in the Kromme Estuary, from November 2021 to March 2022 over the salt marsh growing season. An ex situ feeding experiment was also conducted on 30 crab specimens collected from the Kromme Estuary, during May 2022. These crabs were starved for 48 hours and thereafter fed different components of Spartina (growing and dead blades, and roots and rhizomes). The food consumed was quantified as the change in plant length and dry weight after 48 hours, which gave a maximum grazing rate for the different food sources. It was found that crabs are having a minimal impact on the salt marsh vegetation structure. Spartina maritima does form an important component of the diet of grapsoid crabs, however, this is not their only source of food, and possibly not their preferred source of food. They are however contributing to sediment properties through their burrowing activities. The iii ex situ feeding experiment showed that grapsoid crabs can consume all vegetative components of Spartina, with a significantly greater amount of roots and rhizomes consumed. There was no consistent effect in terms of the exclusion of grazers, indicating that other mitigating factors could be reducing the impacts of grapsoid exclusion in situ. Together, these findings contribute knowledge that can be used to inform conservation by quantifying what the salt marsh risks losing in the absence or overabundance of crabs, as has occurred elsewhere globally. These results influence how salt marshes are managed, and highlight how not recognising the importance of consumers, such as crabs, could misalign management objectives. , Thesis (MSc) -- Faculty of Science, School of Environmental Sciences, 2022

- Description: Ecophysiology studies help understand and predict the response of coastal ecosystems to changes in environmental factors and complement modelling and mapping studies that often do not take into account the physiological tolerances of the biota. Along the South African coastline predicted sea level rise will shift the tidal front and result in larger submerged areas. The frequency and magnitude of inundation and subsequent salinity stress is expected to influence the survival and distribution of salt marsh. An understanding of the effects of sea level rise on plant growth and survival is required to predict, manage and adapt to climate change. The aim of this study was to investigate the response of the salt marsh ecotone species Disphyma crassifolium (L.) L. Bol. to salinity and submergence stress and to measure in situ spatial and temporal changes in vegetation cover and its environmental drivers in the Swartkops Estuary in South Africa.Three greenhouse experiments assessed morphological and physiological responses to salinity and inundation treatments on D. crassifolium. The first experiment used three inundation levels (dry, tidal and waterlogged) and five salinity treatments (0, 8, 18, 35 and 45 ppt) and ran for six weeks. The second experiment also had three inundation levels (dry, waterlogged and completely submerged) and five salinity treatments (0, 8, 18, 35 and 45 ppt) and ran for 12 weeks. The third experiment investigated the response of a narrower range of salinity treatments under dry conditions only; namely 0, 5, 10, 15, 20, 25, 30 and 35 ppt and ran for seven weeks. Experiment 1 showed that D. crassifolium growth decreased with an increase in salinity. Optimum growth occurred at lower salinity treatments of 0 to 18 ppt under dry conditions. Plant height and leaf succulence was the highest at 0 ppt (12.4 ± 1.2 cm and 94.9 ± 0.6 % respectively). The number of leaves produced were the highest at 0 ppt (47.7 ± 8.9 number of leaves) and 8 ppt (59.6 ± 6.3 number of leaves). The root/shoot ratio for dry treatment plants was significantly lower (p < 0.005, n=12) than that of waterlogged and tidal-treated plants. This was as a result of more leaves being produced in dry treatments. In Experiment 2 D. crassifolium plants died after one month of submergence regardless of the salinity. Once again optimum growth occurred at salinity of 0 to 18 ppt under the dry treatment. Within the waterlogged treatment, 0 and 8 ppt treated plants developed adventitious roots and started flowering after two weeks.The electrolyte leakage increased with salinity, however the waterlogged plants had significantly higher electrolyte leakage compare to the dry treated plants. Within the waterlogged treatment electrolyte leakage was at the highest at 18 ppt (36.5 ± 4.2 %) and lowest at 0 ppt (26.1 ± 3.3 %). Photosynthetic pigments showed significant difference across the two inundation states. However, chlorophyll and carotenoids concentrations did not differ significantly with an increase in salinity in each treatment. D. crassifolium tolerated stress through accumulation of solutes that increased in concentration with salinity treatment. The proline concentration ranged between 23.1 to 102 mM while the glycinebetaine concentration ranged between 36.6 and 120 mM. Experiment 3 showed that growth was highest at salinity < 20 ppt. The highest growth based on plant height was measured at 0 and 10 ppt. Spatial and temporal changes in the salt marsh terrestrial boundary was investigated in situ at two sites in the Swartkops Estuary using three line transects per site extending from the terrestrial boundary to the supratidal salt marsh. Plant cover abundance was measured seasonally along with sediment moisture content, electrical conductivity, redox potential, organic content and sediment particle size. There were five sampling trips between April 2016 to July 2017, representing autumn, winter and summer. The transects at Sites 1 and 2 were divided into three zones; a Drosanthemum zone (dominated by Drosanthemum parvifolium (Haw.) Schwantes at the beginning of the transect), a Sarcocornia zone (in the middle of the transect and dominated by Sarcocornia pillanssii (Moss) A.J. Scott) and a Disphyma zone at the end of the transect in the supratidal marsh (dominated by Disphyma crassifolium). There was no significant seasonal change in vegetation cover except in Site 1 during Winter 2016 when Isolepis sp. appeared and was dominant in the middle of the transects. Sediment assessed from each of the zones showed physicochemical ranges within the typical ecotone sediment characteristics. Moisture content ranged between 0.6 and 30.9 % at Site 1 and between 3 and 33.8 % at Site 2. Electrical conductivity ranged between 0.9 and 10.2 mS cm-1 at Site 1 and between 1.4 and 17.8 mS cm-1 at Site 2. Organic content ranged between 1.9 and 16 % at Site 1 and between 3.9 and 16.3 % at Site 2. Redox potential ranged between 208 and 406.7 mV at Site 1 and between 202.7 and 389.67 mV at Site 2. Sediment particle size consisted of sand (>70%), silt (>15%) and clay (<10%). The aim of this study was to provide insight on the effects of salinity and inundation on the morphology and physiology of D. crassifolium occurring in the salt marsh terrestrial boundary and to assess its spatial and temporal changes over time. The research suggests that D. crassifolium is more sensitive to inundation than salinity. Furthermore the succulent was found in the field to be dominant in conditions which the glasshouse experiments showed to be its optimum growth. That is, in dry sediments with salinity of < 18 ppt. Therefore, if these conditions change (sediment moisture and salinity), the cover abundance of D. crassifolium could significantly change in the field.

- Description: The failure rate of small to medium enterprises in South Africa is very high. This is problematic as there is a large dependence on the ongoing success of small to medium enterprises from the economy and society. Increasing labour costs and inflationary pressure have contributed to the high failure rates of small to medium enterprises. In addition, the manufacturing sector for small to medium enterprises has showed a decline over recent years. There is thus a need to identify and manage the critical success factors (CSFs) for small to medium manufacturing enterprises. The balanced scorecard (BSC) has been used successfully to manage CSFs. Furthermore, research on time-driven activity-based costing (TDABC) has illustrated that this costing system could be implemented successfully at small to medium enterprises across the world to manage costs, and that the BSC could be used successfully together with TDABC. However, research has shown that implementing a BSC at small to medium enterprises could be challenging. As a result, the theory of constraints (TOC) that can be used to explain the phenomenon of constraints of resources is recognised as the underlying theory for this study. The availability of a generic yet adaptable BSC could potentially enable owners and managers of small to medium manufacturing enterprises to manage the CSFs that together with the TDABC system can lower costs and identify unused capacity. This study has developed and implemented a generic TDABC/BSC costing system by investigating literature and conducting a Delphi study and a case study at a small to medium enterprise specialising in manufacturing. Firstly, it was found that a generic BSC for small to medium manufacturing enterprises could be developed by using a Delphi study to create a BSC template with optional key metrics/key performance indicators (KPIs) to suit different types of manufacturing industries. Secondly, it was demonstrated in a case study that TDABC could still be beneficial for a small to medium manufacturing enterprise if focus is only on a single product. Thirdly, it became evident that the system could be used to manage the TOC. Finally, the case study shows that cost savings could be achieved in small to medium enterprise by using the integrated TDABC/BSC costing system and by that increase the success of the business.

- Description: The study focuses on Philippi as a particular place and the communities that dwell there. It aims to study the spatial dispositions caused by apartheid and colonialism. The dissertation highlights the inequality of South African cityscapes which is then extrapolated in the conditions that exists on the Cape Flats. A core focus of the study is the way in which architecture might aid the spatial inequality in a post-apartheid South Africa.

- Description: The study focuses on Philippi as a particular place and the communities that dwell there. It aims to study the spatial dispositions caused by apartheid and colonialism. The dissertation highlights the inequality of South African cityscapes which is then extrapolated in the conditions that exists on the Cape Flats. A core focus of the study is the way in which architecture might aid the spatial inequality in a post-apartheid South Africa. The first bottle of wine was bottled in South Africa seven years after the Cape had been colonized. This means that the wine industry has always been synonymous of colonialization to a certain degree.

- Description: The significance of the bond that is formed through animal companionship can be found in narratives throughout history. In fact, often a pet is viewed as an integral part of the family and valued as deeply as a member if not more. This has resulted in numerous studies regarding the incorporation of animals within the therapeutic environment and the unique positive impact of their presence on the client. This study aimed to highlight the healing variables of Animal Assisted Intervention (AAI) as perceived by therapists that actively and purposefully incorporated animals into the therapeutic milieu. A qualitative research approach was utilised for the purpose of this study and semistructured interviews were conducted with a sample of five participants selected through a nonprobability purposive and snowball sampling strategy. Participants included registered Psychologists and Counsellors that had incorporated an animal into the therapeutic environment on at least three separate occasions in order to facilitate the therapeutic process. The participants revealed that the presence of the animal within the therapeutic environment acted as a social lubricant for therapy. This allowed for increased interaction between the therapist and the client, thereby facilitating the process of rapport building and the formation of a therapeutic relationship between the therapist and the client. The presence of the animal was observed as influential in increasing clients’ self-esteem. Likewise, the animal’s presence acted as an instrument in teaching social skills, namely, empathy and responsibility. Clients were additionally observed as more present within the here and now, further enabling the therapist to gain more in-depth information regarding the client’s relational interaction outside of the therapeutic setting. The therapy animal also provided the client with therapeutic touch and affection, a source of distraction, a form of a transitional object or object of projection, as well as a buffer that enabled clients to access and express emotions more freely. This study adds to the body of knowledge available on AAI within the South African context.

- Description: This thesis sets to analyse the provisions of the Work in Fishing Convention (WFC), No. 188 of 2007 and the South African Merchant Shipping Act 57 of 1951 (MSA). This analysis focuses on the regulation of the legal aspects of common practices that result in forced labour and provisions which serve as a deterrence to potential “threats of punishment” used to perpetuate forced labour on fishing vessels. The aim of this analysis is to determine whether South Africa complies with its duties in terms of the WFC. In the process of this analysis, this thesis aims to identify gaps in the MSA that allow for this appalling practice to continue and provide recommendations for amendments to the Merchant Shipping Bill (MSB) based on the identified discrepancies between the MSA and the WFC. Chapter one is an introductory chapter which explains that two elements must be present for a situation to amount to forced labour, namely “involuntariness” and the “threat of penalty.” Chapter two examines South Africa’ s jurisdiction to criminalise, investigate and try fisheries crimes on fishing vessels in different maritime zones. The aim of this examination is to determine whether South Africa has the jurisdiction to criminalise forced labour on fishing vessels in different maritime zones. It is concluded that, while South Africa’s enforcement and adjudicative jurisdiction may be limited in some maritime zones, South Africa has the jurisdiction to criminalise forced labour as a coastal State, flag State, personal State and a port State. Chapter three focuses on global and regional legal instruments to combat forced labour and establishes the significant role of the WFC in combatting forced labour on fishing vessels specifically. It is further concluded that, provided the provisions of the proposed MSB do not change, South Africa currently complies with its duties in accordance with the WFC and goes beyond what is required in some respects. However, South Africa does not comply with its obligation to regulate the recruitment and placement agencies for fishers. This leaves fishers in South Africa vulnerable to coercion by unscrupulous recruitment agencies. It is suggested that the provisions of the WFC relating to the recruitment and placement of fishers can be given effect in South Africa by either amending the current Seafarer Recruitment and Placement Regulations to apply to fishers or by drafting new Merchant Shipping (Fisher Recruitment and Placement) Regulations, which give effect to the WFC in line with the existing Seafarer Recruitment and Placement Regulations and promulgating them in terms of the MSA or its successor. , Thesis (LLD) -- Faculty of Law, School Public Law, 2021

- Description: This study presents an investigation into the visual communication complexities within the genre of documentary film, specifically aimed at the development of a set of criteria of cinematic techniques for the visual communication of environmental awareness issues. This process utilises a theoretical approach to understanding the development and communicative possibilities of documentary film, as well as an analytical interpretation structured on semiotic film theory. The theoretical investigation reveals Bill Nichols’ (2010) documentary modes as an established analytical model. This study engages with four of Nichols’ six modes – namely, the poetic, the expository, the observational and the participatory modes, as the criteria for the extraction of scenes and/or images from Chasing Ice (2012) by Jeff Orlowski and Home (2009) by Yann Arthurs-Bertrand. Once Nichols’ modes have been identified, a semiotic reading is conducted. Gillian Rose’s (2016) visual analysis framework underpinned by Pieter J. Fourie’s (1988) sociological approach to film analysis, is utilised to read the selected film texts. A comparative analysis of Chasing Ice (2012) and Home (2009) reveals that the inclusion of different and multiple modes constructs the visualisation of environmental awareness issues in the documentary film genre. The cinematic techniques specific to the documentary modes represented in Chasing Ice (2012) and Home (2009) are appropriated in the construction of three film shorts within the researcher’s documentary film study, Karoo (2017). This combination of theory and practice yields the researcher a considered and informed approach to constructing documentary imagery aimed at visualising the current environment of the Karoo Basin prior to the possibility of shale gas exploration and/or exploitation.

- Description: Ulwaluko or initiation ceremony is one of the most important ceremonies practiced by the amaXhosa ethnic group to mark male adolescents’ transition from boyhood to manhood. Every young Xhosa male is anticipated to undergo this ceremony in order to be respected and be viewed as a true man by the society. There is a dearth of literature on amakrwala’s views regarding the meaning of traditional beer (umqombothi) and commercial alcohol (brandy or beer) use during the initiation ceremony. Thus, this study addresses this gap, as it adds to the existing spectrum of knowledge on the meaning of alcohol use during the amaXhosa initiation process. The socio-cultural theory was selected as the theoretical framework for the study. This study took a qualitative nature which was exploratory-descriptive and contextual in design employing a non-probability purposive-criterion based technique to sample 16 identified amaXhosa adult males between the ages of 18 to 24 years who recently went through the initiation ceremony. Sixteen individual semi-structured telephonic interviews were conducted. Data collected was analysed using thematic data analysis. Various data verification strategies were employed to ensure trustworthiness. Research ethics applicable to this study were guided by the principles contained in the Belmont report (1979). The findings showed that during the amaXhosa initiation ceremony both commercial alcohol and umqombothi played significant but different roles during each stage of the ceremony. The majority of amakrwala viewed umqombothi as a significant beer for ancestors to divinely bless isiko while brandy and beer were viewed as sweets or beers for fun which accompanied umqombothi. Brandy and beer were viewed as beers required by abafana teaching amakrwala manhood in the lighthouses. Thus, negative behaviours portrayed by abafana during imigidi after drinking alcohol were viewed as a great concern by amakrwala. 7 Alcohol use in ulwaluko was viewed as good by the amakrwala but they emphasized that there should be guidelines that monitor responsible drinking.

- Description: As the global accessibility to the internet and mobile data and cellular systems is on the rise, the ability for the use of mobile devices in order to facilitate banking and to make payment across the African continent will increase. The question is then asked as to whether the African continent is ready for this technology and if it is not at this stage, will this ability to transact with a bank and a trusted method of payment ever be an option in Africa? This needs to be analysed and critically studied to determine whether Africa must invest in this technology and if so, when and how this investment should take place. The ability for the regular African consumer to access the wealth of knowledge that abounds over the internet is critical in order for the new mobile payment initiative to be a success. Education, infrastructure and ability to access this available technology will have long reaching effects in bringing Africa to the forefront in the global economy, while a move away from corporeal and historic tenders such as bartering systems, precious metals or cash, will be something new to the African continent and will need to be explored separately. In this study we will assess the readiness of the top three African economies, namely South Africa, Kenya and Nigeria of their current abilities to facilitate this technology and the barriers to entries and possible remedies to those if this is not the case.

- Description: Operational circumstances often create the need for employers to change the employment conditions of employees. Such conditions can include difficulty in obtaining raw materials which may require employees to do different work, a takeover or a merger, market shifts, orders from clients, an increase or reduction in work volumes, new technology, or even in some instances skill shortages. Regardless of the reason, in order to allow the business to remain operational, employers are often obligated to change terms and conditions of employment. Section 187 of the Labour Relations Act 66 of 1995 deals with automatically unfair dismissals and lists a number of reasons for dismissal that, if it complies with the requirements listed, the dismissal will be found to be automatically unfair. The definition was amended by the Labour Relations Amendment Act 6 of 2014 as a result of the courts incorrectly interpreting this section in Chemical Workers Industrial Union (CWIU) v Algorax (Pty) Limited (2003 11 BLLR 1081) (Algorax) and Fry's Metals (Pty) Limited v National Union of Metal Workers of South Africa and Others (JA9/01) [2002] ZALAC 25 (Fry’s Metals). Section 187(1)(c) of the LRA has always been contentious due to the fact that the definition of automatically unfair dismissals, employers’ rights to terminate contracts of employment on the basis of operational requirements and the institution of collective bargaining are intertwined. The Labour Relations Amendment Act of 2014 brought about significant changes to how section 187(1)(c) should be interpreted and fundamentally changed the enquiry that should be adopted when determining cases of this nature. The main aim of this study is to provide clarity to the question of when will it be valid and fair for an employer, in the course of restructuring his business, to dismiss any of his employees who refuse to accept the proposed changes to the terms and conditions of their employment.

- Description: The global population growth rate is increasing exponentially and is expected to reach nine billion people by 2050. This accelerated population growth and associated increase in food demand, coupled with the trend of decreasing productive agricultural land, present a calamitous food security risk for future generations. The ensuing expansion of agricultural land to supply this food demand leads to irreversible environmental damage including encroachment, climate change and biodiversity extinction. Moreover, rapid urbanisation of the aforementioned over-populace leads to mass unemployment in many major cities and widespread suburbanisation. The concurrence of the latter and former trends creates pockets of urban brown space, unutilised and dilapidated areas that have various consequences. Vertical farming is a system of cultivating crops or food products in buildings, tall structures or vertically inclined surfaces. If applied correctly this method results in substantial increases in crop yield, environmental benefits and reduced pressure on agricultural land. The research problem in this study was to establish how the vertical farming business model can be integrated with urban renewal of brown space to enable profitable and sustainable vegetation production. In order to achieve this objective the following research process was followed: Identification of the factors pertinent for the examination of urban gentrification, vertical farming and business model implementation through the literature review; Identification of approaches for integrating vertical farming applications with urban renewal activities and collective insights from the review of relevant literature; Development of a semi-structured interview guide from the literature review, to determine the extent of perceived utility of vertical farming for revitalisation and to gain valuable insights into strategies for integrating the model; Conducting an empirical study consisting of face-to-face interviews with subject matter experts and/or individuals with experience in the case scope, that were selected through purposive sampling as defined in the research methodology chapter; and Amalgamation and synthesis of the results to develop a proposed integrated model that can be used for urban renewal to create businesses that not only gentrify the urban brown space but that are profitable and provide sustainable development value to the city where it is based. The empirical results obtained from the interviews with respondents were analysed and included in the conceptual framework developed from the examination of secondary data sources. This led to the development of the integrated business model for urban renewal and achievement of the research objectives. The main findings from the research centred on customer segmentation strategy, distribution channels and gentrification through key partnerships. The intricacies of the integrated model and its application are discussed in detail in this research paper.

- Description: The global population growth rate is increasing exponentially and is expected to reach nine billion people by 2050. This accelerated population growth and associated increase in food demand, coupled with the trend of decreasing productive agricultural land, present a calamitous food security risk for future generations. The ensuing expansion of agricultural land to supply this food demand leads to irreversible environmental damage including encroachment, climate change and biodiversity extinction. Moreover, rapid urbanisation of the aforementioned over-populace leads to mass unemployment in many major cities and widespread suburbanisation. The concurrence of the latter and former trends creates pockets of urban brown space, unutilised and dilapidated areas that have various consequences. Vertical farming is a system of cultivating crops or food products in buildings, tall structures or vertically inclined surfaces. If applied correctly this method results in substantial increases in crop yield, environmental benefits and reduced pressure on agricultural land. The research problem in this study was to establish how the vertical farming business model can be integrated with urban renewal of brown space to enable profitable and sustainable vegetation production. In order to achieve this objective the following research process was followed: Identification of the factors pertinent for the examination of urban gentrification, vertical farming and business model implementation through the literature review; Identification of approaches for integrating vertical farming applications with urban renewal activities and collective insights from the review of relevant literature; Development of a semi-structured interview guide from the literature review, to determine the extent of perceived utility of vertical farming for revitalisation and to gain valuable insights into strategies for integrating the model; Conducting an empirical study consisting of face-to-face interviews with subject matter experts and/or individuals with experience in the case scope, that were selected through purposive sampling as defined in the research methodology chapter; and Amalgamation and synthesis of the results to develop a proposed integrated model that can be used for urban renewal to create businesses that not only gentrify the urban brown space but that are profitable and provide sustainable development value to the city where it is based.

- Description: This study dealt with improving service delivery in the National Department of Public Works (NDPW) Polokwane Regional Office through facilities management (FM). It posits that FM can be usefully employed as an instrument to achieve integration of design, construction and FM. It argues that since FM encompasses the essential components of maintenance, refurbishment, reconfiguration and rehabilitation of accommodation it can be usefully utilised to ensure sustainability of government assets. An online data collection method was used to collect raw data from the selected sample. The sample population consisted of assistant directors, control works managers, works managers and administration officers within the FM of Polokwane regional office of the National Department of Public Works.The results show that performance management is not aligned to set service delivery standards and organisational objectives. Monitoring during the implementation of a project is sub- optimal and therefore does not ensure that services are rendered to the satisfaction of the client department. Moreover, there is no establised Management Information Systems (MIS) to keep records of information pertaining to infrastructure; conditional assessments; maintenance; the measurement of the quality of project output; the effectiveness of FM and the procurement policy; and the availability of skills and resources to execute the duties. The set hypotheses were tested by means of evaluation of data collected. The research finally presents a number of professional opinions and recommendations that could be considered to improve service delivery within the FM unit.

- Description: Many rural municipalities are facing challenges in service delivery, and the Greater Taung Local Municipality(GTLM) is no exception. The performance management system plays a pivotal role in the improvement of service delivery and for this to be realised, there are elements that contribute negatively to the system which are a threat and if not managed properly, the aims and objectives of the development would not be possible. The main challenges in the way of implementation of a performance management system, according to the findings, are that the service delivery department of the municipality does not fully comply with the system, non-implementation of the system and/or inadequate skills and knowledge of employees. The aim of the study is to evaluate the utilisation of performance management in the provision of effective service delivery in the Greater Taung Local Municipality. The literature review of performance management has guided the researcher and enables her understanding of performance management system implementation. The main objectives of the research study are therefore to: To determine the purpose of performance management; To determine ways in which performance management improve an employees’ skills and performance; To assess the application of performance management policy at the Greater Taung Local Municipality; and To determine how performance management by the Greater Taung Local Municipality assists in service delivery. A qualitative research method was used to collect data in a form of questionnaires and a literature review, which includes e.g. legislation, policies, journals, books, newspaper articles etc. This method guided the researcher to control the data received by communicating the meaning of what had been learnt during the process of data analysis. The main recommendations of this research study are that more needs to be done in defining the performance management system to employees so that there can be a proper understanding and that a senior official’s perception of the system needs to change. Training would provide the necessary skills for employees to carry out their tasks, thereby meeting the developmental goals of the municipality. In conclusion, the implementation of the research recommendations in this study would improve the utilisation of performance management system and provide effective service delivery in the Greater Taung Local Municipality. , Thesis (MPA) -- Faculty of Humanities, 2021

- Description: A shift towards fully mechanized forest activities, such as harvesting and, more recently, silviculture, has occurred from the early 2 000’s. The reason for mechanizing these activities differs for each country, although for most countries there is concern relating to the health and safety of forest workers. With mechanization in harvesting, the forest worker has moved away from the physical intensity of having to fell, debranch, debark and cross-cut trees into logs using either an axe or chainsaw, to operating a machine. Studies revolving around the human element (operator) have been conducted specifically relating to the ergonomics of the machines and how operators may influence machine productivity. Results showed that due to the repetitive nature of the work, the operators are exposed to associated stresses for longer periods. Typical injuries associated to these kinds of stressors are whole body vibrations (WBVs), repetitive hand and arm movements, non-neutral body postures and manual lifting, which lead to musculoskeletal symptoms in the lower back, neck and shoulders. However, as machine technology improves so does the ergonomic conditions which are experienced by machine operators. Machine productivity can be influenced by various factors, with the most influential being tree volume. However, a recent study showed that over 40% of variation in machine productivity has been observed amongst different machine operators operating similar machines. The specific reason for these differences has yet to be determined. However, decision making, motivation, planning capacity, concentration, memory, motor coordination, pattern recognition, logic reasoning, and spatial perception are abilities that have been described as important for successful harvesting work. The pre-selection of operators using psychometric and cognitive tests is not new to forestry, although very little information is available relating to the aptitude test known as the Vienna test system as well as the best possible demographic associated with successful harvesting operators. The overall aim of this study was to determine whether the high variation found amongst harvesting machine operators could be reduced initially through a preselection process which involves the use of aptitude tests (Vienna Test System) and demographic questionnaires. A study was implemented in Zululand, South Africa, testing whether there were significant productivity differences between nine machine operators. , Thesis (PhD) -- Faculty of Science, School of Natural Resource Management, 2022

- Description: South 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, 2023

- Description: The purpose of this qualitative research study is to comment on the use of photography to visualise abstracted narratives of the emotions associated with trauma. This is a practicebased study developed on the interweaving of theoretical and practical output. The practical output produced a photographic body of work which argues in favour of an abstracted narrative for the visualisation of trauma by engaging with visualised emotions associated with trauma. The theoretical output of the study relates to three visual themes: firstly, the direct or actual moment of trauma; secondly, the triggering of the traumatic experience and lastly, the abstracted narrative of emotions associated with trauma. Photographing a traumatic event freezes a moment in which the subjects are continually engaging in the traumatic experience. Sontag (2003: 93) asserts that this type of direct photographic representation should be discouraged for fear of aestheticising pain and desensitising the viewer to horror. The study aims not to visualise actual traumatic events, but rather to engage with abstracted narratives of emotions associated with trauma experienced or felt, both directly and indirectly. This is achieved by firstly, providing a context on how the role of photography dealing with trauma has evolved to move beyond the depiction of an actual traumatic experience. Secondly, Gillian Rose’s (2016) Visual Methodologies Framework is introduced and photographers Roger Ballen’s Cut Loose (2015) and Jo Ractliffe’s 1999 work entitled Vlakplaas: 2 June 1999 (Drive-by Shooting) analysed as visual expressions of trauma. Similarly, photographers Robert Frank’s 1978 work entitled Sick of goodby’s and Manuela Thames’s 2019 work entitled Trauma are analysed to reflect on the use of abstracted narratives as they comment on personal traumatic experiences. Lastly, the body of work produced in the practice-based output of the study, Public Places: Private Spaces, are analysed as a vehicle through which emotions are associated with trauma. These traumatic experiences are visually expressed using abstracted images in triptych narratives. This study contributes to the current body of knowledge by critically addressing ways of thinking about the visualisation of trauma. This provides insight into the topic of trauma and the various ways in which it could be visualised without depicting the actual trauma (with the potential of continuously wounding or replaying trauma) and instead engaging with the visualised traumatic experience as an abstracted narrative within a South African context. , Thesis (MA) -- Faculty of Humanities, School of Visual and Performing Arts, 2021

- Description: This study provides an investigation into the current transition socio-culturally concerned photographers are making from traditional two-dimensional flat imagery, towards three-dimensional materiality based photographic installation artworks. According to Dr. Gillian Rose (2016), larger society is found to be in a state of oculacentrism, where vision and visuals are central to contemporary every day experience, resulting in the medium of photographic expression not being used and experienced by the average person as an art medium at all. So much so that these traditional photographic forms of visual communications have found a decline in visual engagement and subsequently visual impact. In an attempt to combat this change in the relationship between photographic imagery and audiences, select socio-cultural photographers are adopting practices incorporating three-dimensional, immersive installation techniques (Shore, 2014: 7-11), (Lister, 2007: 272). The aim is to provide a three-dimensional installation space, where the audience is encouraged to engage with socio-cultural issues. The study focuses specifically on two sociocultural photographers, Damien Schumann and Angelica Dass, who have communicated socio-cultural stories in this three-dimensional photographic installation space. In order to analyse and derive valuable techniques and approaches from their selected works The Shack (2010) and Humanae (2017) the study combines sections of Dr. Gillian Rose’s Visual Methodologies Framework (2016) as well as installation analysis tools designed by author Mark Rosenthal (2003). The same analytical criteria are then applied to the practical components socio-cultural topic communicating the Stigmatism Towards Persons With Albinism in Sub-Saharan Africa. The study concludes having created a three-dimensional photographic installation exhibition using similar techniques identified within the selected artists, moving beyond twodimensional forms to present a combination of three-dimensional techniques for enhanced socio-cultural visual communications.

In order to analyse and derive valuable techniques and approaches from their selected works The Shack (2010) and Humanae (2017) the study combines sections of Dr. Gillian Rose’s Visual Methodologies Framework (2016) as well as installation analysis tools designed by author Mark Rosenthal (2003). The same analytical criteria are then applied to the practical components socio-cultural topic communicating the Stigmatism Towards Persons With Albinism in Sub-Saharan Africa. The study concludes having created a three-dimensional photographic installation exhibition using similar techniques identified within the selected artists, moving beyond twodimensional forms to present a combination of three-dimensional techniques for enhanced socio-cultural visual communications.

- Description: South Africa is considered to be the economic power house of Africa, yet still lags behind when implementing energy efficient solutions. This can be attributed to bureaucracy and red tape. South Africa is the smallest importer and user of liquefied petroleum gas in Africa. Algeria is the biggest importer and consumer on a domestic scale. The use of liquid petroleum gas as an automotive fuel is not a new concept, either on this continent or the rest of the world. Vehicles have been driving on autogas for many decades and have seen various technological changes and improvements along the way. The latest autogas technology has been tried, tested and improved to be in line with Euro 5 standards. The purpose of the paper is to highlight all the benefits to motorists and to encourage the adoption of liquid petroleum gas (Autogas) as an automotive fuel. The literature review highlights the financial and environmental benefits, as well as identifying the barriers to adoption as well as the critical success factors for adopting autogas as a transport fuel. This resulted in the identification of six independent variables, namely cost, environmental impact, government legislation, infrastructure, public demand and product availability. These variables were then used to construct a conceptual framework to test the perceived outcome, which was the dependant variable.
