- Description: This study seeks to understand land use decision-making dynamics on large residential plots in Fingo Village, Makhanda (Grahamstown). Fingo Village was selected as a study area because it is one of the poorest urban settings in South Africa where urban poverty is observed alongside access to land. A dominant economic perspective not only suggests that land use decisions are motivated by economic motives, but also implies that access to land would enable people to generate income from its use to improve their livelihoods. This study argues against an uncritical embrace of this assumption. Lefebvre’s production of space thesis provides a holistic understanding of the factors involved in the making of land use decisions. The focus of this study is on the dialectic process in the spatial triad– spatial practice, representational space and representations of space. This involved the reading of government policies and legislation together with local lived experiences to gain an understanding of the particular spatial practices seen in Fingo Village. Snowball and convenience sampling were used to select 36 household plots in Fingo Village. Primary data was gathered by means of semi-structured interviews and participatory mapping while additional information was sourced from secondary sources and desktop analysis. The findings of the study show that there is no uniform pattern of land use and success. Different land use activities found on the selected residential plots, including the main house, backyard flat or flats, spaza shops, a funeral parlour, livestock keeping, cultural use (a kraal for ancestral worship) and food gardening. These activities are motivated by residents’ perceptions and attitudes towards their spaces, as well as the value and meaning they attach to the land which is not limited to economic factors, but is also influenced by socio-cultural, political and biophysical considerations. Although some spatial practices are prohibited by the government, they are important to the residents. Other participants fail to use the land as would be expected by a conventional economic perspective, due to spatial conflict relating to different interests as a result of collective land ownership and the failure of municipalities to enforce policies and regulations. The fact that numerous factors influence households’ land use decisions means that access to land does not always directly translate into economic benefits. It is all about what people think or do about their land, as well as what the state lays out in terms of policy and legislation, that will influence whether those people with large plots of land will ‘prosper’ or not. , Thesis (PhD) -- Faculty of Science, Geography, 2021

- Description: The “privacy paradox” is the term used to describe the disconnect between self-reported privacy value attributions and actions actually taken to protect and preserve personal privacy. This phenomenon has been investigated in a number of domains and we extend the body of research with an investigation in the IoT domain. We presented participants with evidence of a specific IoT device’s (smart plug) privacy violations and then measured changes in privacy concerns and trust, as well as uptake of a range of behavioural responses. Our Saudi Arabian participants, despite expressing high levels of privacy concerns, generally chose not to respond to this evidence with preventative action.

- Description: Time remains a frequently discussed issue in physics and philosophy. One interpretation of growing popularity is the ‘timeless’ view which states that our experience of time is only an illusion. The isolated Universe model, provided by the Wheeler-DeWitt equation, supports this interpretation by describing time using clocks in the conditional probability interpretation (CPI). However, the CPI customarily dismisses interaction effects as negligible creating a potential blind spot which overlooks the potential influence of interaction effects. Accounting for interactions opens up a new avenue of analysis and a potential challenge to the interpretation of time. In aid of our assessment of the impact interaction effects have on the CPI, we present rudimentary definitions of time and its associated concepts. Defined in a minimalist manner, time is argued to require a postulate of causality as a means of accounting for temporal ordering in physical theories. Several of these theories are discussed here in terms of their respective approaches to time and, despite their differences, there are indications that the accounts of time are unified in a more fundamental theory. An analytic analysis of the CPI, incorporating two different clock choices, and a qualitative analysis both confirm that interactions have a necessary role within the CPI. The consequence of removing interactions is a maximised uncertainty in any measurement of the clock and a restriction to a two-state system, as indicated by the results of the toy models and qualitative argument respectively. The philosophical implication is that we are not restricted to the timeless view since including interactions as agents of causal interventions between systems provides an account of time as a real phenomenon. This result highlights the reliance on a postulate of causality which forms a pressing problem in explaining our experience of time.

- Description: A novel mono-porphyrin (2) was employed for the photodegradation of 4-chlorophenol and 4-n-nonylphenol at pH 10.60. A partially modified polyacrylonitrile (PAN) polymer was utilized only as a support system for the photosensitiser to allow the formation of a covalent linkage. Complex 2 showed singlet oxygen values of 0.70 in dimethyl formamide and when conjugated (2-PAN) showed 0.39 in water. When employed against 4-chlorophenol a degradation efficiency (η) of 29.1% was achieved at 0.20 mol L−1 over a period of 10 min. When employed against 4-n-nonylphenol we obtained a η of 26.7% at 0.17 mol L−1 over a period of 10 min.

- Description: The star-forming regions (SFRs) in the peculiar galaxies NGC 660, NGC 1512, NGC 4395 and NGC 4618 are studied. The relationships between such characteristics of star forming regions as UV, near- and far-IR fluxes, as well as in the Hα and HI lines, surface brightness in these ranges, and the scatter of the radial velocities of ionized and neutral hydrogen are considered. It is shown that in all the galaxies considered, the IR fluxes from SFRs are less than in the “normal” galaxies, but for different reasons: in the galaxies with signs of recent interaction NGC 660 and NGC 1512, this is due to the low surface brightness of SFRs; in the lopsided galaxies NGC 4395 and NGC 4618, the low brightness of SFRs in the infrared range is due to their compact size. These differences indicate that the star formation process depends not only on the morphological type of a galaxy, but also on many other factors.

- Description: The right to access health care services is enshrined in section 27 of the Constitution. It is a right afforded to everyone. The state is required to adopt legislative and other measures for the progressive realisation of this right. To that effect, the state has passed various pieces of legislation aimed at realising the right to access health care services. The key legislative measures regulating the health system are the National Health Act, the Medical Schemes Act and the Medicines Act. Despite the various legislative measures in place, not everyone has access to health care services and there is a need for reform in the health system. To remedy the problem of inaccessibility, the government introduced the NHI Bill in 2018 which was amended in 2019. The NHI Bill purports to amend the way in which health services are financed. The purpose of this research is to determine the constitutionality of selected aspects of the NHI Bill. Section 27(2) of the Constitution requires that any measure adopted by the state in realising the right to access health care services must be reasonable. This research, therefore, assesses whether the NHI Bill is a reasonable measure that meets the requirements of section 27(2). The NHI Bill will be assessed in light of the reasonableness review used to assess state compliance with the obligation in terms of section 27. In assessing the reasonableness of the NHI Bill, reference is made to the domestic obligations of the state to realise the right to access health care services, the context in which the NHI Bill was published, the provisions of international law, and the impact the NHI Bill will have on other rights specifically the right to equality. The findings of this research are that the NHI Bill is likely to be found unconstitutional insofar as it unfairly discriminates against asylum seekers and undocumented migrants and lacks clarity with respect to important issues such as the role of medical schemes. Based on this analysis, recommendations are made to ensure that the NHI Bill is constitutionally sound.

- Description: Purpose: Stage 3 of the pharmaceutical process validation lifecycle, is called continued process verification (CPV). CPV is the final stage of lifecycle management and is intended to provide ongoing assurance that during routine production that a process remains in a state of control. Since CPV is a relatively new focus area for regulators, many legacy products will not have undergone Stage 3 process validation. Therefore, an opportunity existed to review the impact and challenges of implementing CPV on a legacy product. Methodology: This study employed quantitative analysis to evaluate the impact of CPV on process stability and end product quality for Product X, a legacy product manufactured at a generics manufacturing facility. Initial Stage 3a CPV was used to review historical process data and identify special cause variation. Corrective and preventative actions were taken to address these statistical outliers and the impact of these process changes were evaluated in Stage 3b. Results: CPV implementation appeared to have an effect on process control, stability and capability for Product X. In Stage 3b, an increase in statistical outliers along with significant changes to process mean and standard deviation were seen for the critical process parameters, average mass and hardness. An improvement in process capability for the critical quality attributes, assay and dissolution, was also seen. Conclusion: The largest benefit of CPV implementation, especially for a legacy product, is the process knowledge gained. This provided opportunities for process improvement and ultimately benefited patient safety.

- Description: There is a lack of data on the physical activity, physical fitness and sedentary behaviour of children in South Africa. Furthermore chronic diseases such as type II diabetes and coronary heart disease have been linked to childhood inactivity, and improving cardiorespiratory fitness and increasing levels of physical activity has been shown to be beneficial in reducing the risk of such diseases. In South Africa more broadly there is a lack of information on levels of physical activity and sedentary behaviour as well as physical fitness measures particularly in children. Objective: The purpose of this study was to enhance the existing body of knowledge on this, by measuring the prevalence of physical inactivity, sedentary behaviour and screen time of primary school children in a private school from the Makana Municipal region in the Eastern Cape Province of South Africa, where the evidence is most sparse. A secondary aim was to assess levels of physical fitness in this cohort, as well as to compare across grades and sexes. Method: After ethical approval was granted, stature and body mass measurements were taken and body mass index was computed for primary school children (Grade one to seven) from a private school in the Makana Municipality. Sitting stature was measured in order to determine each child’s peak height velocity and maturity offset. Five different physical fitness tests were conducted on the children and blood pressure and heart rate values were measured at rest. Physical activity and screen time questionnaires were completed by the children’s parents for a seven day period. Results: Females were found to mature faster than males. In addition females were more physically active (Females= 916 min/week; Males= 669 min/week) while also accumulating more sedentary time (Females= 1241 min/week; Males= 970 min/week) as compared to males, although no significant differences were found between males and females for these variables. The sample participated in more than 60 minutes of moderate-to-vigorous physical activity and less than two hours of screen time daily, which is in accordance with guidelines. No differences were found between grades and sexes for accumulated screen time. Strength increased significantly with grade and age, and there were also statistical differences between the sexes for all three strength measures with males being stronger than females. Females were more flexible than males and no statistical differences were found between sexes for the shuttle run test. Blood pressure correlated positively with mass, as did all the strength measures as well as maturity offset. No correlations were found between screen time and all other variables. A negative relationship was recorded between screen time and physical activity, although not significant. For females a strong positive correlation was found between sedentary behaviour and physical activity. Conclusion: The study was successful in adding to the body of knowledge regarding the prevalence of physical inactivity, sedentary behaviour and screen time within school children from the Makana Municipality in the Eastern Cape Province of South Africa. The sample was considered physically active as they accumulated on average more than 60 minutes of moderate-to-vigorous physical activity daily (Males= 96 min/day; Females 130 min/day), which is in accordance with guidelines recommended by the World Health Organization (World Health Organization, 2018). The sample accumulated more sedentary behaviour than physical activity, although not significant. Screen time was below regulations of two hours daily, indicating this population participated in more non screen related sedentary behaviour. More research is needed into the risks presented with different forms of sedentary behaviour. Physical fitness increased with increasing grade and age and males were considerably more fit. The current study did not present any concern with regards to the effects of increased physical activity and fitness levels within school aged children. More research into the current levels of physical activity, physical fitness and sedentary behaviour of school aged children in South Africa in general, and in the Eastern Cape Province, is needed. , Thesis (MSc) -- Faculty of Science, Human Kinetics and Ergonomics, 2021

- Description: There is a lack of data on the physical activity, physical fitness and sedentary behaviour of children in South Africa. Furthermore chronic diseases such as type II diabetes and coronary heart disease have been linked to childhood inactivity, and improving cardiorespiratory fitness and increasing levels of physical activity has been shown to be beneficial in reducing the risk of such diseases. In South Africa more broadly there is a lack of information on levels of physical activity and sedentary behaviour as well as physical fitness measures particularly in children. Objective: The purpose of this study was to enhance the existing body of knowledge on this, by measuring the prevalence of physical inactivity, sedentary behaviour and screen time of primary school children in a private school from the Makana Municipal region in the Eastern Cape Province of South Africa, where the evidence is most sparse. A secondary aim was to assess levels of physical fitness in this cohort, as well as to compare across grades and sexes. Method: After ethical approval was granted, stature and body mass measurements were taken and body mass index was computed for primary school children (Grade one to seven) from a private school in the Makana Municipality. Sitting stature was measured in order to determine each child’s peak height velocity and maturity offset. Five different physical fitness tests were conducted on the children and blood pressure and heart rate values were measured at rest. Physical activity and screen time questionnaires were completed by the children’s parents for a seven day period. Results: Females were found to mature faster than males. In addition females were more physically active (Females= 916 min/week; Males= 669 min/week) while also accumulating more sedentary time (Females= 1241 min/week; Males= 970 min/week) as compared to males, although no significant differences were found between males and females for these variables. The sample participated in more than 60 minutes of moderate-to-vigorous physical activity and less than two hours of screen time daily, which is in accordance with guidelines. No differences were found between grades and sexes for accumulated screen time. Strength increased significantly with grade and age, and there were also statistical differences between the sexes for all three strength measures with males being stronger than females. Females were more flexible than males and no statistical differences were found between sexes for the shuttle run test. Blood pressure correlated positively with mass, as did all the strength measures as well as maturity offset. No correlations were found between screen time and all other variables. A negative relationship was recorded between screen time and physical activity, although not significant. For females a strong positive correlation was found between sedentary behaviour and physical activity. Conclusion: The study was successful in adding to the body of knowledge regarding the prevalence of physical inactivity, sedentary behaviour and screen time within school children from the Makana Municipality in the Eastern Cape Province of South Africa. The sample was considered physically active as they accumulated on average more than 60 minutes of moderate-to-vigorous physical activity daily (Males= 96 min/day; Females 130 min/day), which is in accordance with guidelines recommended by the World Health Organization (World Health Organization, 2018).

- Description: Contaminants in fish is a concern globally and locally. Fish have the propensity to accumulate contaminants to levels that may pose a threat to human health and disrupt ecosystem function. The purpose for investigating contaminants in this study for fish provides the public with information on the potential human health risks from the contaminated fish we consume. This study also investigated contaminants in estuarine fish and sediment, and is important to monitor as these components of ecosystems can indicate contamination in estuaries. Effective methods to determine contaminants in fish and sediment included the Direct Mercury Analyser 80 for mercury, Gas Chromatography for fatty acids and polychlorinated biphenyls and Inductively Coupled Plasma for aluminium, arsenic, cadmium, chromium, cobalt, copper, iron, lead, manganese, mercury, nickel, vanadium and zinc. Basic statistical tools, geochemical techniques, a bioaccumulation model and human health risk assessment tools provided by the United States Environmental Protection Agency were used to interpret the data. Ultimately consumption advice was developed from the risk assessment results and showed predatory fish such as swordfish and bluenose species are recommended to be avoided while yellow tail, red roman, mackerel, fish fingers and canned tuna are some of the fish that can be eaten 10-14 times per month that would not cause potential health risks. It was found that estuarine ambassid fish investigated in this study were not suitable for contaminant monitoring. There were no clear spatial and seasonal trends observed in the estuaries suggesting that ambassid fish efficiently assimilate contaminants. There was little evidence that contaminants were transferred from sediment to ambassid fish in the eThekwini estuaries. Therefore, their use is limited as a cost-effective estuarine contaminant monitoring tool. Each estuary investigated is unique and requires its own management plan.

- Description: Managing risk in intensively managed monoculture plantation forests is an essential task to ensure sustainable yield and a continuous flow of forest products. However, since risks can be either biotic or abiotic, not all of them have a predictable pattern of spread, which can cause severe losses if management does not have the chance to implement mitigation action. Monitoring the change in forest health is vital as this provides the opportunity for preventative management and quantifies the amount of damage that management has to deal with. To provide this window of opportunity for appropriate action, constant monitoring is required. Until recently, forest health was measured through field surveys which provided adequate data. This procedure, however, is time consuming. Remote sensing has become very popular as a monitoring tool, due to its ability to provide assessment data in a fraction of the time. In this study, baboon damage in plantations along the Mpumalanga escarpment area of South Africa was monitored using remote sensing methods. While there are many methods of forest health monitoring using remote sensing, some approaches are less suitable as they either monitor damage caused at a plantation level, use lower spatial resolution (>10m) datasets or map damage using one available time period. The purpose of this study was first to establish the impact of baboon damage through time, using Sentinel-2 satellite imagery with all vegetation indices available, and the Extreme Gradient Boosting (XGboost) algorithm. The second part focused on analysing the damage at a tree level using PlanetScope imagery using a deep Learning approach. Overall, the study found that the use of Sentinel-2 data and PlanetScope data could accurately distinguish between the varying severity of baboon damage, achieving an accuracy of 95% and 82%. The processing time of the deep learning Artificial Neural Network (ANN) was greatly affected by the number of hidden layers and neurons used. Implementation of techniques used in this study has the potential to improve the accuracy of forest health monitoring in compartment forestry in South Africa.

- Description: Subtidal habitats have not yet been accounted for in habitat maps of South African estuaries. In this study, a novel method for mapping subtidal estuarine habitats, using a remotely operated underwater vehicle (ROV) piloted from a boat, was developed and tested in the Knysna Estuary. Video footage was recorded along 48 transects across the width of the estuary, and then reviewed to identify, classify and map habitats. Using the method developed in this study, 21 hours of footage was recorded over 15 days of sampling, and about 30 hours of post-processing was carried out to map an area exceeding 850 ha. This study has produced the first baseline dataset of subtidal habitats for a South African estuary. Additionally, the study revealed the previously unknown distribution of the invasive red seaweed Asparagopsis taxiformis, and the underestimation in previous studies of the estuary of area cover of eelgrass Zostera capensis by 130 ha.

- Description: The African Acacia species Vachellia karroo, V. robusta, V. nilotica, and V. tortilis are some of the most invasive species implicated in bush encroachment and woody thickening of historically open savannas in southern Africa. This is partially explained by historic increases in atmospheric CO2 concentrations, which are proposed to have promoted the growth and survivorship of C3 tree seedlings relative to C4 grasses. However, the uniformity of CO2 responsiveness and differences among Vachellia species remain largely undetermined. Here we investigate the growth and photosynthetic responses of four Vachellia species, all implicated in woody encroachment, but originating from distinct climatic niches. Exposing these species to a range of sub-ambient CO2 concentrations (12 – 40 Pa) showed that V. karroo, V. robusta, V. nilotica and V. tortilis all responded strongly and fairly consistently to increasing CO2 concentrations, acting as a ‘functional type’ despite being selected from different geographic regions and having different climatic niches. Combined average net CO2 assimilation rates increased by 130% despite significant, but low levels of down-regulation and decreased stomatal conductance. The increased photosynthetic rates stimulated growth and biomass production in all compartments, with no significant differences in interspecific above and below ground allocation. Growth rates and dry biomass increased by 50% and 186%, respectively, while leaf level water use efficiency (ratio of net CO2 assimilation rate to transpiration rate) increased by an average of 218%. When this was scaled to the whole plant level, this stimulation was decreased to 80%. The decrease was the result of the CO2 stimulated increase in canopy areas, which increased leaf area for water loss. The seedlings’ total number of spinescent physical defenses, as well as the average mass and spine mass fraction also increased with rising CO2. These thicker spines could act as better deterrents against vertebrate browsers. Spine density was unchanged, however, showing that the increased spine numbers were associated with larger seedlings at higher CO2 rather than an increase in the number of spines per stem length. The stimulatory effects of increasing CO2 concentrations since the last glacial maximum and resultant increases in seedling growth and biomass are likely to have had important consequences for the survival and establishment of Acacia seedlings. Tolerance of drought and disturbance has been related to seedling size, hence stimulating the growth rate could confer disturbance tolerance and this tolerance would develop more rapidly with increasing CO2 concentrations. Furthermore, increased nitrogen and water use efficiency have the potential to support seedling establishment in environments where these resources would otherwise be limited at lower atmospheric CO2 concentrations. Resulting in a larger proportion of CO2 fertilization responsive woody seedlings surviving the seedling size classes, and persisting within historically open savannas. Where interspecific differences occurred they are likely to have arisen from adaptation to specific climates where these species are native and selection would have been driven by factors such climate, resource availability, levels of disturbance and competitive interactions. V. karroo had the highest growth rates and strong CO2 driven increases in biomass accumulation, despite having the lowest inherent photosynthetic rates. V. karroo also had the lowest increase in water use efficiency and high transpiration rates could potentially increase access to soil nutrients through mass flow. This species had the highest mean spine mass and showed significant increases in spine mass fraction at elevated CO2 concentrations, which may be important for deterring herbivores. V. robusta’s distribution to the mesic east coast of Africa suggests that water is an important limitation to its distribution. Hence, the CO2 stimulated increase in water use efficiency at both leaf and whole canopy level allows speculation that this may be an important driver of this species’ range expansion, which might continue if increasing levels of CO2 continue to promote water use efficiency. V. nilotica occupies a broad range of habitats, inhabiting large areas of the subtropics both north and south of the equator, with the strongest climatic correlates being the precipitation of the wettest quarter followed by high temperature seasonality. In response to increasing CO2, V. nilotica showed overall strong increases in growth, water use efficiency, and physical defenses. These responses may explain why V. nilotica has been such a successful encroacher in a broad range of habitats where limitations are likely to include multiple climatic factors and disturbances. V. tortilis has the widest distribution of all the species studied, covering broad ranges of Africa and only being excluded from the wettest parts of the equator and driest parts of the deserts. In these experiments this species showed the lowest biomass responsiveness to CO2, but had especially large increases in water use efficiency at both the leaf and canopy level. This may have been an important driver for this species’ encroachment into the more arid parts of its distribution, however this link will need to be verified with further experimentation.

As an African youth myself, I know that we are a diverse group with different backgrounds, perspectives and beliefs. I am interested in exploring our identities, how we express ourselves and how we make sense of ourselves, each other, the continent and the world. I want to learn more about how we see the world, and what we think of how media narratives and messages represent us. This research project is an extension of this personal curiosity. It focuses on Black Panther, a film that received particularly strong responses from young black Africans. I want to explore why this film in particular prompted such a strong reaction, and what the imagining of an uncolonised, technologically advanced African nation that Black Panther offers means for the young black Africans born after the official end of apartheid and colonisation.

- Description: As the potential for shale gas exploitation becomes a real possibility across parts of the Karoo in South Africa, and groundwater is one of the systems that could become heavily stressed if the shale gas industry becomes operational, it is important therefore to gain a better understanding into the hydrogeochemical systems and processes that occur within the Karoo Basin. Groundwater systems are very complex and are heavily relied upon in many areas across the Karoo that are surface water deficient. Groundwater is used domestically, for irrigation and livestock as well as in industry. A hydrogeochemical baseline investigation was undertaken in the shallow Karoo Basin aquifers (< 100 m) of the Border-Kei region with in the Eastern Cape of South Africa, which flanks the Indian Ocean. Since it has been suggested that seawater might be used as a potential fracking fluid, it is important to also establish baseline data linked to potential seawater salinisation in the coastal aquifers. This was achieved by sampling water from both 35 production and 3 non-production boreholes (by making use of a bailer and discrete interval sampler). Water from all 38 samples was analysed for major anions and cations, trace elements as well as for δ 18O and δ 2H stable isotopes. Results indicate that the majority of the groundwater in the study area falls within acceptable limits for domestic use, and although slightly saline, is exploitable for other uses as well. It was also found that dolerite dykes that have intruded into the Karoo Basin sediments have slight effects on the groundwater chemistry, but that these effects are also masked by the water-rock interactions occurring with the aquifer. It was also determined with major ions and stable isotopes that although the coastal aquifers do have saline signatures (EC > 200 mS/m) this is not due to salinisation via seawater intrusion. It is instead postulated that the salinity arises from marine aerosols that have introduced NaCl onto the soil layer, and which then leaches into the groundwater system through precipitation or irrigation. In the event of shale gas extraction through fracking or the expansion of rural and urban centres, this project serves as a preliminary hydrogeochemical baseline before any of these processes proceed within the Karoo Basin.

Results indicate that the majority of the groundwater in the study area falls within acceptable limits for domestic use, and although slightly saline, is exploitable for other uses as well. It was also found that dolerite dykes that have intruded into the Karoo Basin sediments have slight effects on the groundwater chemistry, but that these effects are also masked by the water-rock interactions occurring with the aquifer. It was also determined with major ions and stable isotopes that although the coastal aquifers do have saline signatures (EC > 200 mS/m) this is not due to salinisation via seawater intrusion. It is instead postulated that the salinity arises from marine aerosols that have introduced NaCl onto the soil layer, and which then leaches into the groundwater system through precipitation or irrigation. In the event of shale gas extraction through fracking or the expansion of rural and urban centres, this project serves as a preliminary hydrogeochemical baseline before any of these processes proceed within the Karoo Basin.

- Description: As a “Non-Annex 1” country, there was no obligation for South Africa to reduce its carbon emissions. South Africa undertook, of its own volition, to take measures to reduce 34% of the carbon monoxide emissions by 2020 and 42% by 2025 respectively. In response, South Africa promulgated the Carbon Tax Act, No. 15 of 2019. This study seeks to answer the question: After analysing the range of environmental taxes levied in the Scandinavian countries (Denmark, Finland, Norway and Sweden) and in South Africa, are there lessons that can be learnt for South Africa? In answering this question, the carbon tax structure in South Africa and in selected Scandinavian countries is analysed, together with existing environmental taxes and the related policies, using a literature study. What is evident from the Scandinavian countries studied, is that environmental taxes have distributional effects and are effective in reducing carbon emissions. The major result of the study was that the real weakness of the newly introduced Carbon Tax Act is that in both in the first and second phase of its implementation, the carbon tax rate is too low to send an appropriate signal to the market and would not have the desired outcome. In addition, there are currently no guidelines that inform the revenue recycling technique to ensure transparency of revenue usage, improved energy management, or how the Carbon Tax Act will promote environmental quality. A major concern is that carbon tax revenue will not be ring-fenced. Given that South Africa is a developing country and depends mainly on non-renewable energy, it is inevitable that most of its sectors will be subject to the carbon tax. A plausible approach is the one that promotes the idea of taxing those more heavily that contribute most to environmental degradation and are highly energy concentrated, to promote parity between the harm to the environment and the taxes levied to redress the harm.

- Description: iv ABSTRACT The nucleus of this study is youth crime and the rehabilitation of the youth caught up in criminal activities. Conducted in Alice in the Eastern Cape, South Africa, this study scrutinized youth crime prevention techniques utilized in Alice and surrounding areas, and it established their efficacy. The study investigated the elements of rehabilitation available for young offenders in this area. With the social control theory, the structural strain theory and the risk-needs-responsivity guiding this study, the findings revealed that loss of control by conventional institutions, strains that individuals experience and inadequate rehabilitation are determinants of youth crime in and around Alice. With lack of resources as well as inconsistent and inadequate application of these programs, efficacy in minimizing and preventing youth crime proves to be low. At some point in the past, communities had effective diversion programs for the youth but these were no longer practiced. Findings revealed that the root causes of youth crime in this area include poor economic background, youth unemployment, broken families, peer pressure and substance abuse among other causes. Prevention programs do not correspond to the actual causes of crime, and, as such, youth crime prevention programs will not achieve efficacy until they address root causes. On the other hand, rehabilitation is of great importance to achieving minimal youth crime rates. The findings revealed that imprisonment is the only source of rehabilitation for young offenders in Alice, and that it yields positive results, albeit for a short period. This is due to neglect of the causes of crime and utilizing general prevention and rehabilitation. The environment into which the young offenders are placed after v socioeconomic status, unemployment, peer pressure and drug abuse. These result in strains that drive young people to committing crime; consequently, engagement in youth crime leads to loss of social control and it becomes an on-going cycle. The risk-needs-responsivity model emphasizes constructing rehabilitative treatment based on the risk the individual poses to society, including the likelihood to reoffend, the offender‟s needs that might lead the individual to deviant ways of achieving them, and the environment into which the individual is exposed. The study adopted a mixed-methods approach. To obtain qualitative data, the researcher made use of 5 focus group discussions each comprising at least 6 members of the community, in-depth interviews with 15 young offenders who had experience with the justice system, and an in-depth interview with the chief community policing officer of the Alice town police department. For the attainment of quantitative data, questionnaires were administered to 100 community members with 61 usable questionnaires upon retrieval. Qualitative data was analysed using the thematic analysis technique while the quantitative data was analysed using the Statistical Package for Social Science (SPSS) software. In view of the theoretical framework, weak social bonds and ties to family, school and society at large play a role in the engagement of youth in criminal activities. This spawns a loss of control to some extent and, due to this, individuals will experience strain as they have abandoned genuine ways of attaining needs and achieving goals, in this case adopting new illegitimate ways of meeting their needs. This calls for rehabilitation that is tailored specifically for the offender: treatment that addresses the risk the offender poses to society; needs of the offender that may lead to reoffending; the social context and the role it is anticipated to play once the offender gets out of rehabilitation. The key is who to target, what to target and how to target it. vi The study concludes that in order to make crime prevention techniques effective, the first step is addressing the root causes of youth crime given that general techniques have been used and indicate no efficacy due to the neglecting of the social context when arriving at problem solving techniques. These become unbeneficial as they attempt to control crime without getting rid of the causes of crime. Rehabilitation should be directly proportional to offender risk and needs. Specific rehabilitation that is determined by offender risk and needs should be practiced for the achievement of long-term rehabilitation.

- Description: This article, which focuses on African noir as a variety of neo-noir literature, begins by outlining the intertextual and intercultural relationships between classic noir and African noir. Thereafter, the postcolonial, postmodernist and transnational elements of African noir are described utilizing Mũkoma wa Ngũgĩ’s novel Black Star Nairobi (2013) and Leye Adenle’s When Trouble Sleeps (2018) as exemplars. Arguing that African noir draws on various genres and discourses, the article demonstrates how issues of socio-political justice, ontological and existential dilemmas, aesthetic concerns and the epistemological quest are rendered as ambiguous and murky. Based on a close reading of Black Star Nairobi and When Trouble Sleeps, the article concludes that the predominant chiaroscuro effect of African noir is not so much a ‘dark’ sensibility as one of abstruseness and poignant Afro-pessimism.

- Description: The study aimed to reveal the existence of corruption within the public sector and to propose strategies to eliminate it within the supply chain management procurement processes and infrastructure within the public sector in the Province of the Eastern Cape. The study employed a mixed method of quantitative and qualitative data analysis. For the quantitative approach, a series of structured questionnaires were issued to employees within the public sector, many of whom are involved in the procurement process. The officials were asked to rate the views on the importance of the Batho Pele principles in the public sector, risks that may result to the project failure in the public infrastructure sector and the most prevalent causes of corruption For the qualitative method of the study, interviews were conducted for both civil servants and non-public servants who have been involved in procurement processes and coordinating projects. Also, the investigation units were interviewed to determine their views on corruption in the public sector. In addition, the study involved 92 officials within the Eastern Cape Province, and eight interviews were carried out. Initially, 101 public officials were to participate in the study. According to the information that was gathered qualitatively and quantitatively, the most effective methods of eradicating corruption within the procurement department of the public sector are the following: transparency in rules and policies, strengthening of internal audit, management of domestic politics, the emphasis of government focus on preventative rather than curative methods of eliminating corruption, strengthening of consequence management and introduction of anti-corruption committees. Giving monopolistic powers to one person was seen as a gateway to fraud. The research was limited to the views of the officials who are involved in procurement processes in the Province. Not only does the study uncover the possible causes of corruption and its level in the public service but offers constructive recommendations to eliminate it with the hope that economic development will be fostered and the infrastructural climate of the Eastern Cape enhanced.
