- 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: The MeOH/CH2Cl2 (1:1) extracts of the roots and leaves of Beilschmiedia louisii and B. obscura showed potent antitrypanosomal activity during preliminary screening on Trypanosoma brucei brucei. Phytochemical investigation of these extracts led to the isolation of a mixture of two new endiandric acid derivatives beilschmiedol B (1) and beilschmiedol C (2), and one new phenylalkene obscurene A (3) together with twelve known compounds (4–15). In addition, four new derivatives (11a–11d) were synthesized from compound 11. Their structures were elucidated based on their NMR and MS data. Compounds 5, 6, and 7 were isolated for the first time from the Beilschmiedia genus. Additionally, the NMR data of compound 4 are given here for the first time. The isolates were evaluated for their antitrypanosomal and antimalarial activities against Tb brucei and the Plasmodium falciparum chloroquine-resistant strain Pf3D7 in vitro, respectively. From the tested compounds, the mixture of new compounds 1 and 2 exhibited the most potent antitrypanosomal activity in vitro with IC50 value of 4.91 μM.

- Description: Motivation in the workplace is the willingness of employees to exert high levels of effort in achieving the organisations goals and objectives. Motivation has been studied by psychologists and organisational experts throughout the ages and was consistently found that motivated employees provide organisations with improved productivity and a competitive edge. Millennials, born between the years of 1980 and 2000, are the biggest cohort since the baby boomer to enter the workplace. A significant amount of research was done on the characteristics of millennials but there is a limited amount of empirical research done on understanding and potentially improving motivation of millennials. The automotive industry is a key player and contributor to South Africa’s gross domestic product and employs a great number of people in direct and indirect jobs throughout the value chain. Against this backdrop, research was conducted within the automotive sector in the Gauteng and Eastern Cape (Nelson Mandela Bay) regions in South Africa aimed at exploring motivation under the context of leadership, communication, social responsibility, rewards and, given the tech savvy nature of millennials, the use of technology. This study was conducted under the positivistic paradigm, which employed a quantitative approach, by means of a questionnaire survey. The study and review of the literature by the researcher found that millennials value leadership which supports, and guides as oppose to enforces. Communication, which is transparent, concise but frequent. They are willing to make personal sacrifices working for an organisation who genuinely cares about Environment.Furthermore, millennials demand using technology to improve efficiency and interestingly, regards career development more than money as the most important and rewarding aspect. By understanding the motivational factors of millennials, Leaders can be equipped to keep them engaged, motivated and highly productive, after all, they are not only the future, but are fast becoming the present.

- Description: On 1 March 2019, the United Nations (UN) General Assembly (New York) declared 2021–2030 the “UN Decade on Ecosystem Restoration.” This call to action has the purpose of recognizing the need to massively accelerate global restoration of degraded ecosystems, to fight the climate heating crisis, enhance food security, provide clean water and protect biodiversity on the planet. The scale of restoration will be key; for example, the Bonn Challenge has the goal to restore 350 million km2 (almost the size of India) of degraded terrestrial ecosystems by 2030. However, international support for restoration of “blue” coastal ecosystems, which provide an impressive array of benefits to people, has lagged. Only the Global Mangrove Alliance (https://mangrovealliance.org/) comes close to the Bonn Challenge, with the aim of increasing the global area of mangroves by 20% by 2030. However, mangrove scientists have reservations about this target, voicing concerns that it is unrealistic and may prompt inappropriate practices in attempting to reach this target (Lee et al., 2019). The decade of ecosystem restoration declaration also coincides with the UN Decade of Ocean Science for Sustainable Development, which aims to reverse deterioration in ocean health. If executed in a holistic and coordinated manner, signatory nations could stand to deliver on both these UN calls to action.

- Description: This research sets out to examine institutional culture and internationalisation in higher education in contemporary South Africa, by analysing the experiences of black foreign academics at Rhodes University. Much has been written on the adaptation processes of foreign students in South African universities (Ayliff and Wang, 2006; Dzansi and Monnapula-Mapesela, 2012; Mudhovozi, 2011). There is also a host of literature on the black South African experience of adaptation and (non) belonging at historically white universities (HWU) (Akoojee and Nkomo, 2007; Cornell and Kessi, 2017; Soudien, 2008). Comparatively less is written on whether there are any unique pressures regarding institutional culture that black foreign African academics face at historically white institutions such as Rhodes University. The black experience may be misrepresented as a homogenous one by much of the literature on higher education transformation (Batsai, 2019). But there are a host of factors that could change your experience of being ‘black’, such as your class, and gender and quite recently there has been a push to further examine the effect that one’s nationality has on their experience of being ‘black’ in the academy (Batsai, 2019). Institutional culture refers to the “behaviours and values that make up the unique psychological and social environment of a certain institution” (Toma et al., 2005). Internationalisation of higher education in the context of Africa, particularly South Africa refers to “the intentional or unintentional process to integrate intercultural, international and global dimensions in higher education” (Draft Policy Framework for the Internationalisation of Higher Education in South Africa, 2017). In analysing the experiences of international African academics, this research is trying to give a voice to an often-overlooked group of individuals. This research is also meant to portray the black experience in South African higher education as an experience that is not homogenous but reliant on a host of unique identity factors such as gender, class and also their nationality.

- Description: Perceived nature disconnection lies at the heart of the world’s socio-ecological crisis. Finding ways to reconnect with nature is fundamental towards reducing the adverse psychological–social– ecological consequences of this disconnection. Understanding the psychological and social benefits of nature-based experiences is important towards actualising reconnection. This article discusses such benefits for child and adult participants from the Eastern Cape, South Africa. This work stems from Ecopsychology research with an outdoor education centre, Mystic Mountain. The experiences of two groups of children (n=25, aged 10–14years) and adult instructors (n=12, aged 18–50years) were explored using interpretive case-study methodology. Through semi-structured interviews and focus groups, participant observation, and reflexive journaling, data were collected and analysed thematically. This article centralises participants’ perceived psychological and social benefits of nature-based experiences as mediators of deeper self and nature connectedness. Integrating these benefits into nature-based pedagogy-design processes could contribute towards more effective enhancements of nature connectedness, and in turn, foster Earth’s larger flourishment.

- 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 Okavango River Basin is a hotspot of bat diversity that requires urgent and adequate protection. To advise future conservation strategies, we investigated the relative importance of a range of potential environmental drivers of bat species richness and functional community composition in the Okavango River Basin. During annual canoe transects along the major rivers, originating in the central Angolan highlands, we recorded more than 25,000 bat echolocation calls from 2015 to 2018. We corrected for possible biases in sampling design and effort.

During annual canoe transects along the major rivers, originating in the central Angolan highlands, we recorded more than 25,000 bat echolocation calls from 2015 to 2018. We corrected for possible biases in sampling design and effort.

- Description: This thesis argues that within the conventional imagination of the West, identity functions in a way that particular forms of embodiment are characterised by the experience of endured sexual vulnerability, which I argue is best understood as the construction of ‘rapeable’ bodies (Cahill 2001, 120). By this, I mean that the threat of rape is contingent upon the social and political construction of one’s identity as vulnerable. In virtue of this particular way of constructing the embodiment of certain subjectivities, there is an instance of hermeneutical injustice conferred (Fricker 2007, 114). I inquire into the function and meaning of stereotypic generalisations, prejudice and rape myths embedded within the dominant framework of the West and show how language and representation constructs these identities as ‘rapeable’. Furthermore, I consider how collective hermeneutical discourses construct Blackness, specifically Black masculinities and the construction of the ‘un-rapeable’ Black femxle body. To see how these ideas are congruous the prominent example that occurred in South Africa in 2005, namely, the Jacob Zuma rape trial comes to mind. One relevant feature of the case is that it shows how identities of race are constructed in the aftermath of apartheid and points to a Western collective imagination resistant to change. In addition, it demonstrates the triad of interrelatedness holding between the self-world-other, a relationship constituted mutually by the self and the socially constructed interpretations of identity and embodiment (du Toit 2009, 58). Lastly, the construction of ‘rapeable’ bodies is an example of how discursive narratives construct particular identities as vulnerable through rendering particular embodied subjects as sexually irrelevant and hermeneutically obscured.

- Description: Throughput rates and transformation have long been considered major challenges to accounting departments in South Africa. While much research has been done on various aspects of study techniques in an attempt to assist students to succeed, little attention has been paid to profiling students to ascertain whether there are common traits in terms of personality, aptitude, values and motives, which distinguish successful students from others. This study looks at these factors and uses sub-tests of the Differential Aptitude Test (DAT), selected with reference to the South African Institute of Chartered Accountants (SAICA) Competency Framework, to determine the correlation between these aptitudes and the success of accounting students. In addition, the impact of biographical data, including gender, race and type of school attended, is considered on the success of the students and the individual sub-tests of aptitude. The study then considers the impact of various personality types, personality traits and values on the success or failure of accounting students, and finally seeks to ascertain whether there is a holistic profile of a student who has a statistically significant chance of succeeding in accounting studies. Results indicate that the sub-tests of aptitude for verbal reasoning and reading comprehension have the most significance in predicting student success and that gender and race have a medium effect. Furthermore, personality types, personality traits and values do not have a significant impact on student success. The only biographical factor to have an impact on success was race.

- Description: Many of today’s news headlines are fraught with alarming accounts of fraud and Corruption conducted by business leaders and this study was undertaken to investigate the influence of perceived ethical leadership on employee engagement. The question has arisen whether these unethical actions among business leaders impact the perceptions of employees and whether this affects their engagement with the organisation. There has been an increase in studies on employee engagement, due to the significant positive impact that it has on an organisation and the beneficial outcomes that engaged employees produce. In this study, the research design followed a positivist approach. The research participants consisted of middle managers in the public or private sectors in South Africa. Sampling was done using a non-probability convenience sampling technique. Secondary data was collected using research data from the Nelson Mandela University Library and its online database. Primary research data was collected using self-administered, standardised questionnaires making use of a 5-point Likert scale. Data was interpreted by means of inferential statistics and biographical information. Every precaution was taken to ensure the reliability, validity and trustworthiness of the study. Ethical approval was obtained for the study from the Nelson Mandela University Research Ethics Committee as per the protocols that were in place at the time of the data collection. This study is significant in terms of the upsurge in unethical conduct in the business arena. The primary objective of this research was to determine the influence of perceived ethical leadership (Perceived Leader Integrity) on employee engagement (the factors which constitute engagement are job commitment, job satisfaction and future intentions.). In the findings, a moderate relationship was found between PLI and job commitment and job satisfaction. A negative relationship was established between PLI and future intentions. Therefore, ethical leadership had an influence on employee engagement.

- Description: Metabolically induced drug-toxicity is a major cause of drug failure late in drug optimization phases. Accordingly, in vitro metabolic profiling of compounds is being introduced at earlier stages of the drug discovery pipeline. An increasingly common method to obtain these profiles is through overexpression of key CYP450 metabolic enzymes in immortalized liver cells, to generate competent hepatocyte surrogates. Enhanced cytotoxicity is presumed to be due to toxic metabolite production via the overexpressed enzyme. However, metabolically induced toxicity is a complex multi-parameter phenomenon and the potential background contribution to metabolism arising from the use of liver cells which endogenously express CYP450 isoforms is consistently overlooked. In this study, we sought to reduce the potential background interference by applying this methodology in kidney-derived HEK293 cells which lack endogenous CYP450 expression.

- Description: In South Africa, Psychology has had a chequered past mainly due to its role in the justification of apartheid policies. Due to apartheid's socio-economic injustices, confidence in the applicability of psychological knowledge to South Africa's social problems was insufficient. Psychologists attempted to raise consciousness of the social relevance of psychology by contributing relevant knowledge and being reactive to social inequalities and related psychosocial issues affecting South Africa. This study aimed to conduct a content analysis of trends in research produced by Psychology Masters' students in the fields of Clinical, Counselling and Research psychology over a period of 5 years (2008-2012). The corpus of data was then compared with the key issues raised in the United Nations Development Programme's South Africa human development report (2003), along with a focus on articles published by Macleod (2004) and Macleod and Howell (2013). It emerged that Empirical Qualitative studies, based on post-modern frameworks, as well as HIV/AIDS, Knowledge Production, Assessment and Measurement and Programme development and evaluation, dominated psychological research. Participants were mainly urban, middle class adults living in the 3 wealthiest provinces. University students were the most popular participant group. While it is encouraging that students were attempting to engage with psychosocial issues, the limited number of key social issues addressed, the under-representation of certain sectors of the South African population, as well as the impact of socioeconomic status on well-being requires greater attention at Masters' level to ensure Psychology's psychosocial relevance.

- Description: Currently there is a perception in South Africa that projects undertaken on parcels of restituted land are experiencing a much higher failure than success rate. There are, however, a few projects that are reaping the rewards and uplifting their communities, as intended by the land redistribution program. One community in particular, located in Mpumalanga, called community A, is presently undertaking a development project. This development project is one of the most successful restituted land parcel projects ever in South Africa. The purpose of the study is to determine the critical success factors in this community development project that have allowed it to enjoy such high levels of success. Are these critical success factors different from the generic industry critical success factors and, if so, what are they? As informed through literature, the critical success factors focused on in this study are as follows: the influence of management, project communication, knowledge management, the role of senior management, business strategy, project success measurements, and training and development. For the empirical study, a physical questionnaire was handed to 35 management members currently employed in the community development project. The questionnaire requested the demographics of all participants and asked them to rate, using a five-point Likert scale, their perceptions of the present project activities and of the importance of the project activities mentioned in making the project successful. Participants had to indicate the extent to which they agreed with each statement in the questionnaire. The responses obtained from the survey were presented and analysed. The study found that the critical success factor “role of senior management” was the largest problem area in the restituted land development project. “Training and development opportunities” came in second, with both factor areas showing large variances. Recommendations have been given on how to address both these problematic areas in the development project and how future restituted land parcel projects can better utilize these factors to ensure successful project implementation and long-term project success.

- Description: This thesis utilises an interdisciplinary approach to understand the political significance of the experimental poetics used by Claudia Rankine in Citizen: An American Lyric and Koleka Putuma in Collective Amnesia. Rankine and Putuma offer contemporary reflections on what it means to occupy marginalised spaces in society. These artists experiment with formal and conventional aspects of literature to explore and create new definitions of what it means to be Black in society. Their works and techniques allow for thinking outside of dominant ideologies of race and posit alternative Black identities that are not found within canonical theory on Blackness. This project reflects on existing theories of Black subjectivity as evident in Frantz Fanon’s Black Skin, White Masks and Aimé Césaire’s Notebook on the Return to My Native Land. While these theorists did not reject the role of Black women in Western civilisation, they should be read as a moment in a series of counter-discourse to the Black Other rather than the finite canon of Black subjectivity. The emergence of Rankine and Putuma’s experimental poetics works to disrupt the conflation of the Black subject with the Black heteronormative male. Using Michelle M. Wright’s Physics of Blackness as its primary theoretical framework, this project advocates alternative and disruptive readings of Blackness that potentially shift Blackness away from its conflation with nationalism, masculinity and heteronormativity. This thesis uses a dialogical approach between political theory and literature which allows for Citizen and Collective Amnesia to be read as acts of resistance to epistemological erasure and as articulations of the politics relevant to the poets’ lived experiences. Both the United States and South Africa have a history of institutionalised racial segregation, which allows Rankine and Putuma to be read in relation to one another. Where the Civil Rights movement and the anti-apartheid struggle were both foregrounded as male-lead liberation movements contemporary social movements including #blacklivesmatter and #feesmustfall have initiated a return to the androcentric philosophies of Malcom X and Steve Biko, for example. As such Rankine and Putuma’s literature and art marks a reclamation of female empowerment and visibility in the face of a political rhetoric that continues to be masculine and nationalist in nature. In the absence of a space where Black female and queer bodies are adequately recognised, the poetry they write creates a space of self-representation and recognition.

- Description: Namibia is a member country of the Common Monetary Area (CMA) with Lesotho, Swaziland and South Africa. South Africa is the anchor country to which the smaller member states have surrendered monetary policy authority. This thesis therefore examines the empirical relationship between the South Africa repo rate (SArepo) on the one hand and Namibia’s repo rate (Namrepo), Prime Lending Rate (PLR), Private Sector Credit Extension (PSCE), Consumer Price Index (CPI) and Gross Domestic Product (GDP) on the other hand. The credit channel of the monetary policy transmission mechanism informs the theoretical foundation of the thesis. Vector Autoregression modelling, variance decomposition and impulse response functions were used to explore the nature and strength of the relationship between the SArepo and said variables in Namibia. This thesis used quarterly data for the period 2003 to 2017. The variation in the Namrepo was predominantly explained by the SArepo, which confirmed that the Namrepo strongly followed the SArepo. The impulse response function results found that the impact of a contractionary monetary policy shock (an increase in the SArepo) lasted for up to six quarters before the effect started to fade. The Namrepo exhibited a positive response to an increase in the SArepo, although the magnitude of the response started to fade after the third quarter. The PLR, as a representative of market rates in Namibia, also exhibited a positive response to an increase in the SArepo. The results were similar for the Namrepo and the PLR because changes to the NamRepo are passed through immediately to the market interest rates. On the real variables, the study found that a contractionary monetary policy shock initiated in South Africa resulted in an increase in inflation in Namibia of less than 0.4 percent, whereas output declined by less than 1.0 percent. Interestingly, a Namibia (domestic) contractionary monetary policy shock resulted in a decline in prices of less than 0.4 percent. GDP, on the other hand, exhibited a positive response to a contractionary monetary shock, with an increase of less than 2.0 percent in the first four quarters of the period observed. The results reflected that a contractionary monetary policy shock from South Africa was more effective with regard to its impact on GDP; however, a domestic monetary policy shock was more effective at impacting on domestic inflation compared to the impact from South Africa.

- Description: Namibia is a member country of the Common Monetary Area (CMA) with Lesotho, Swaziland and South Africa. South Africa is the anchor country to which the smaller member states have surrendered monetary policy authority. This thesis therefore examines the empirical relationship between the South Africa repo rate (SArepo) on the one hand and Namibia’s repo rate (Namrepo), Prime Lending Rate (PLR), Private Sector Credit Extension (PSCE), Consumer Price Index (CPI) and Gross Domestic Product (GDP) on the other hand. The credit channel of the monetary policy transmission mechanism informs the theoretical foundation of the thesis. Vector Autoregression modelling, variance decomposition and impulse response functions were used to explore the nature and strength of the relationship between the SArepo and said variables in Namibia. This thesis used quarterly data for the period 2003 to 2017. The variation in the Namrepo was predominantly explained by the SArepo, which confirmed that the Namrepo strongly followed the SArepo. The impulse response function results found that the impact of a contractionary monetary policy shock (an increase in the SArepo) lasted for up to six quarters before the effect started to fade. The Namrepo exhibited a positive response to an increase in the SArepo, although the magnitude of the response started to fade after the third quarter. The PLR, as a representative of market rates in Namibia, also exhibited a positive response to an increase in the SArepo. The results were similar for the Namrepo and the PLR because changes to the NamRepo are passed through immediately to the market interest rates. On the real variables, the study found that a contractionary monetary policy shock initiated in South Africa resulted in an increase in inflation in Namibia of less than 0.4 percent, whereas output declined by less than 1.0 percent. Interestingly, a Namibia (domestic) contractionary monetary policy shock resulted in a decline in prices of less than 0.4 percent. GDP, on the other hand, exhibited a positive response to a contractionary monetary shock, with an increase of less than 2.0 percent in the first four quarters of the period observed. The results reflected that a contractionary monetary policy shock from South Africa was more effective with regard to its impact on GDP; however, a domestic monetary policy shock was more effective at impacting on domestic inflation compared to the impact from South Africa.

- Description: Over the past decades parental involvement in education has increased rapidly within disadvantaged schools in South Africa. This transformation is evident in the legislation of the country which celebrates a spirit of Ubuntu in a democratised society, and, education at large. The ideal of effective school-home partnership across racial boundaries are, for example, emphasised and strengthened via parental involvement at all public schools. Parents, according to the Department of Education (DoE, 1996b:11; 2000c:29; 2001b:29; 2008:23; 2009:17; 2014b:27; n.d.:6), are considered key role-players in school governance and encouraged to support equal educational opportunities for all learners. It implies that the praxis of parental involvement – especially at disadvantaged schools – is a huge benefit to learners with existing backlogs in education. In relation to this view, Stofile and Green (2007:63) emphasise the significance of parental involvement in school life as it can assist greatly in addressing the divere needs of disadvantaged learners. The dynamics associated with parental involvement are investigated in this study through two cycles of participatory action research. Initially ten parents from one of the disadvantaged primary schools within the Nelson Mandela Bay Metropole were purposively selected to participate in an in-depth qualitative research study pertaining to the design of a suitable parental involvement programme for disadvantaged learners. All the relevant information was gathered during action learning sets, individual interviews, and observations to triangulate the data and fill in possible gaps. This data was coded and categorised throughout the cyclical process via inductive participatory data analysis, as described by Patton (2015:216 & 551). Three main themes with sub-themes emerged from the study, namely (1) deficits of the academic programme: remedial education, teacher-assistants, homeworksupport, technical abilities; (2) the neglect of social wellness programmes: need for parental guidance, necessary professional assistance, upgrading of safety measures, availability of clothing bank, sustainability of a nutritional programme; and (3) voids in communication and relationships: the home environment, community, school environment. These themes and sub-themes successfully answered all the research questions. An increasing number of learners at disadvataged primary schools are neglected and/or leave school at a very young age. This scenario is often linked to poor communication and/or a lack of adequate educational support programmes to enhance better learning outcomes. The design of a PIP aimed to address the diverse needs of learners at a specific disadvantaged primary school with the full cooperation of their parents. Nested within the Ecological Model of Bronfenbrenner, the participating parents were engaged in comprehensive discussions about educational support programmes that the school could embark on with them. Numerous programmes were identified as fundamental to transforming the quality of education for many disadvantaged learners. This research therefore encouraged greater parental involvement at disadvantaged primary schools in order to sustain better learning outcomes.

- Description: Worldwide, households’ consumption of electricity contributes to a substantial proportion of total national energy demand. Thus, the residential sector is a major entity in efforts to define and achieve global sustainability goals. Understanding electricity use behaviour and factors underlying behaviour is critical for designing behaviour change interventions, particularly in contexts characterised by fast-growing economies, burgeoning number of high-income households, and consumption growth. However, relative to developed economies, very little is known on this subject in South Africa. Using structured questionnaires, this study examines electricity use behaviour among high-income households in Johannesburg, South Africa.
