- Description: This article is based on research conducted by a group of plurilingual postgraduate students from different disciplines who facilitated writing groups at the Centre for Postgraduate Studies at Rhodes University over the past two years. It is based on self-reflective writing of language biographies and aims to raise attention about, and to open up a discussion on, the impact of social and personal language practices. We approach the role of language not only as complex interrogation of academic identity, but also as sense of embodied self, an active element in the formation of geo- and body-politics of knowledge which has been highlighted in recent literature focussing on translanguaging in education and decolonising the curricula of Higher Education. Following selfguided research, we engaged in a critical reflection on the use of home languages in education and consulted relevant literature that argues for the inclusion of translanguaging practices in Higher Education. Our research, therefore, focuses on new epistemologies afforded by a shift away from the monolingual habitus and from the concept of multilingualism towards plurilingualism and translanguaging. Our data suggests that a plurilingual approach towards teaching and learning in Higher Education can afford epistemological access to learners across faculties and disciplines in Higher Education, and we argue that the role of languages of tuition in curricula need to be strategically re-evaluated.

- Description: Geography is widely recognised in Namibia as a subject within the curriculum that has been framed for understanding and resolving environment issues and sustainable development. It is in this light that this study examined the inclusion of opportunities for environmental education (EE)1 embedded in the Grade 11-12 Geography curriculum in the Namibian context. This study is undertaken as a case study of two schools in the Omusati region in northern Namibia. It investigated opportunities for EE that are embedded in the Geography curriculum using action competence as a lens to review the curriculum and how teachers are working with it in two rural school contexts. This study employed qualitative methods, specifically semi-structured interviews, an analysis of curriculum documents, classroom observations and focus group interviews. Ethical issues were taken into consideration throughout the study. The key findings from the study are: 1. The specification of EE has mainly emerged as a series of concerns that present as topics to be taught and compared with similar concerns in other parts of the world; 2. Teachers have little experience of what and how to teach and inform environmental education within their classrooms; 3. Learners are not actively involved in seeking and probing environmental concerns or in seeking solutions to these. These findings have been used to make recommendations that teachers: 1. Revisit and review the curriculum documents to carry theory into classroom practice; 2. Encourage learners’ participation to enhance their interest and emotional responsibility in environmental education. The study concludes by calling for further research into EE in Geography. This can be used to improve EE in the region where this study was conducted and beyond. , Thesis (MEd) -- Faculty of Education, Education, 2021

- Description: Commercial property development and investment provide many benefits to individuals and governments around the globe; these include the generation of income for investors, employment, tax revenues, and contributions to a country‘s GDP. Yet commercial property development and investment projects involve construction, economic and management risks. A lack of effective risk assessment and management tools may lead to developers and investors incurring losses. To curtail such losses, this study sought to create a credible management model that can be used to assess and manage risks in Ghana‘s commercial property development and investment industry. An extensive literature review was done, covering all 12 identified study constructs: real estate trends and cycle, construction project management, outside advice/mentorship, spatial development, strategic factors, business management skills, PMBOK, PESTEL analysis, general management skills, governance structures, financial feasibility, professional feasibility, and risk management. Each construct was defined and operationalised. A positivistic philosophical approach was used, and quantitative approach was used to solicit data from the main respondents through the distribution of questionnaires to the target population sample. CB-SEM and SPSS version 24 were used to analyse data, SEM to test the positive relationships hypothesised between the identified variables and SPSS to analyse the demographic data. The major findings are that there is a lack of financial and professional feasibility analysis among respondents along the following factors: the PMBOK, real estate trends and cycles, general management, business management, strategic factors, spatial development, and PESTEL analysis. It was found that these factors have positive and favourable influences on CPDI projects. The study recommends that developers and investors do financial and professional feasibility studies before they embark on projects. This could improve project viability in commercial property development and investment. The study has contributed to the body of knowledge in CPDI sector by developing a new risk assessment/risk management model. , Thesis (PhD) -- Faculty of Engineering Built Environment and Technology, School of the built Environment, 2023

In so doing, the study was based on the following questions: What is the relationship between leadership styles of HODs and employee job satisfaction in a Higher Education institution in the Eastern Cape Province of South Africa. A purposive sampling technique was utilised to select the participants, which comprised 80 academic staff members to which the researcher hand-delivered 80 questionnaires. The study employed a quantitative method to collect and analyse data. The study found that Perceptions on the leadership styles of academic HODs at the HEI are varied. No clear pattern emerged on what leadership styles are prevalent. The relationship between leadership styles and employee job satisfaction appears to be nonlinear. Job satisfaction is a phenomenon that is determined by many factors, not simply leadership styles.

Although this phenomenon is well researched, teachers’ experiences of stress remains a worrying challenge particularly to schools’ effectiveness. This study sought to establish how monitoring and management mechanism that can assist teachers to cope with stress challenges. These are some of the recommendation: that the school disciplinary committee should be trained in various disciplinary measures that may be implemented in the school to curb learner ill-discipline and lack of commitment, that working relationship should be built between schools and the Department of Basic Education, motivational speakers and educational counsellors should meet with all learners on a regular basis to motivate them to have high desire for and interest in education and to build their self-confidence in the classroom, providing all the schools with healthy environment in classrooms, provision of learning and teaching materials to all schools, schools should set up an effective school-parents partnership in order to promote a safe drug and alcohol free environment, employ enough teachers in all secondary schools and the Department of Basic Education at district level should make room for stress management workshops for teachers.

- Description: Although extensive studies and investigations exist within provincial and national spheres of the craft making and trading sector in South Africa, most of these investigations have aimed to conceptualise craft and the identification of the obstacles, as well as the demurred in the craft industry as whole. However, not much is known about immigrant traders in the African craft market. The objective of this study was to investigate the process involves in the manufacturing and trading of woodcraft, stones carving and beads stores owned by immigrant traders. The study utilised a desk methodology to review literature in Green Market Square, Stellenbosch Craft markets, Hout Bay Craft Market and Franschhoek Craft market. The findings revealed that the art of wood carving uses cutting tools to make wooden figures, ornamental objects and sculptures. The beads are made of fine glass, broken and unusable bottles and other varieties of scrap glass. The finding also revealed that most craft businesses are seasonal the markets do not have shades and unpredictable weather pattern in Cape Town is also a problem, which limits growth prospects.The study recommended that policy makers should developed these markets.

This call must be considered within the transformation discourse that arose in South Africa after the fall of the apartheid regime in 1994 and the need to equalize educational opportunities, reduce poverty and improve lives through education. All this underscores the need for a vibrant motivated, satisfied and dedicated workforce. To explain and understand the phenomena of job-satisfaction several theories have been suggested by Maslow, Vroom, Adams, McGregor, Herzberg, Alderfer’s and other authors, however theories on employee job satisfaction varies with time and place, the old theory needs to be either modified, or replaced with a new model. The study attempt to synthesize the theories of job satisfaction in the Higher Education Institution in Eastern Cape Province in South Africa. The study adopted a desktop that was designed primarily as a descriptive study to source literatures on motivation, job satisfaction, and theories. Theories are neither right nor wrong rather it depends on the context where it is applied. Theories need to be restructured according to the new areas of research in human psychology. The evidence established from this study suggest theories of job satisfaction have to be tested against these emerging factors of positive psychology and their impact on human behaviour at individual, group and organizational levels in other Higher Education institutions in South Africa. Keywords: Motivation, Job Satisfaction, Theories, University.

- Description: This study was inspired by the need to increase entrepreneurial opportunities in South Africa. It analysed the opportunity presented by tourism as a possible entrepreneurial field for you entrepreneurs from Universities. The study was based on the position that despite the attacks on colonial heritage sites, they can present possible entrepreneurial opportunities. The study adopted the quantitative approach to collect and analyse the perceptions of entrepreneurship students at a Higher Education Institution. Evidence was found that there were many benefits of heritage entrepreneurship which included creating financial viability, creation of employment and improving the environment and infrastructure in communities. It was also found that most of the students held a positive impression of the role of tourist and tourism entrepreneurship in the communities. They held a good image of the tourist and felt that they did not offer any threat to locals. Youth are recommended to adopt heritage tourism entrepreneurship as employment opportunity.

- Description: The paper draws attention to the profit motive in respect of survivalist entrepreneurship at a township environment in Cape Town. Survivalist entrepreneurs have received little specific focus yet they represent a significant portion of economic activities in South Africa townships. Essentially the study considers the problem of failure to grow among survivalist entrepreneurs as reported in related literature. Many survivalist entrepreneurs fail to grow beyond the survivalist phase and there is no consensus on the underlying cause for such a phenomenon. With the Covid-19 pandemic, there is an expectation that survivalist entrepreneurs are likely to multiply owing to the collapse of many small businesses as well as the loss of employment arising from the pandemic. Two specific objective were formulated for the study: (1) to inquire into the business motives of survivalist entrepreneurs and (2) to assess the perception of the survivalist entrepreneurs on the degree to which the small business environment in supportive of motive attainment. The study adopted a quantitative research design based on the selection of respondents using a convenience sampling strategy. The evidence established from this study suggest that survivalist entrepreneurs do not pursue the profit motive significantly but they faced inhibitions presented by the economic environment in which they operate. Government and other stakeholders in the national economy are recommended to develop a suitable legal and institutional framework with strong structures to ensure the growth of survivalist entrepreneurs Keywords: Survivalist Entrepreneur, Township Entrepreneurship, Profit Motive, Small Businesses.

- Description: ZnO nanoparticles were manufactured using microwave-assisted combustion. The structural and morphological properties of the nanoparticles were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy, and Fourier transform infrared spectroscopy. Photocatalytic degradation of ortho-nitrophenol (O-NP) in aqueous solution using the synthesized nanoparticles was performed under UV–C irradiation and is reported for the first time. The effect of the initial O-NP concentration, amount of photocatalyst, pH, and salt was investigated during photodegradation. Analysis of the degraded samples using HPLC with UV detection revealed that photocatalysis in the presence of ZnO nanoparticles removed 98% of the O-NP in 5 h. In addition, the photocatalytic degradation kinetics of O-NP were studied, and the results suggest that the data are best fitted to pseudo-first-order kinetic and Langmuir–Hinshelwood models.

- Description: In the process of achieving social equity and local development in Ghana, the empowerment and improvement of the lives of women remain critical factors, because of the existing role women and girls assume in the household and larger communal setting. In Northern Ghana culture and religion have historically side-lined, and in some cases, completely excluded women from participating in the dialogues, economic and political processes that lead to, or facilitate the transformation and development of their households and communities. Even though the media has largely contributed to the discrimination and stereotype of women through how women are represented in mainstream media, the Ghanaian media, in its assumed role as the “fourth estate of the realm” has the power to explicitly advocate and implicitly frame messages which can accelerate the processes of social change, women’s empowerment and social inclusion through the community radio broadcast system (Diedong, 2017: pp. 59, 64). After 30 years of the liberalization of the Ghanaian media and 25 years after the opening of the first community radio station, there have been few studies of how community radio influences women’s empowerment, how it gives opportunity for women to participate in political processes and whether, and how, it strengthens the livelihood capabilities of women. This research was motivated by the empowerment theory and the theory of participatory development communications. The researcher also makes references to feminist media theory in his arguments about the need for women to have access to radio in order to make their own content and also listen to content produced by other women. This study adopted a mixed methods research approach and collected data through programme analysis of the sampled radio stations, focus group discussions and semi-structured interviews. After field data was collected, they were analysed in themes that focus on the objectives of this study, data is presented through thematic discourse methods in order to help the researcher draw conclusions and propose a framework to guide practitioners in the implementation of communication for development projects which use mass media in targeting women for development objectives. My analyses are broadly presented in three chapters with each chapter focusing on one research objective. Based on the data, the researcher discovered that, community radio improves the livelihoods of women in Northern Ghana by providing them with agricultural programming which teaches women new farming techniques and how to practice sustainable agriculture while improving the yield of their crops. The study also found out that community radio provides. opportunities for women to monitor how public funds meant for community development projects are allocated, disbursed, and used for their intended purposes, by creating an avenue of two-way communication and dialogue between women, their district officers, and their elected leaders. Based on the findings of the study, the researcher concludes that, it is important for development practitioners who use mass media to implement women-focused projects to conduct a contextual analysis of the communities, the women, and the identified stakeholders of the intended project because every community is unique. Whereas all women in rural areas are vulnerable and underprivileged. To some extent, their needs and preferences are different because of their different levels of education and income status. , Thesis (PhD) -- Faculty of Humanities, School of Language and Communications, 2022

- Description: Coastal communities are some of the most at-risk populations with respect to climate change impacts. It is therefore important to determine the vulnerability of such communities to co-develop viable adaptation options. Global efforts to address this issue include international scientific projects, such as Global Learning for Local Solutions (GULLS), which focuses on five fast warming regions of the southern hemisphere and aims to provide an understanding of the local scale processes influencing community vulnerability that can then be up-scaled to regional, country and global levels. This paper describes the development of a new social and ecological vulnerability framework which integrates exposure, sensitivity and adaptive capacity with the social livelihoods and food security approaches. It also measures community flexibility to understand better the adaptive capacity of different levels of community organization. The translation of the conceptual framework to an implementable method is described and its application in a number of “hotspot” countries, where ocean waters are warming faster than the rest of the world, is presented. Opportunities for cross-cultural comparisons to uncover similarities and differences in vulnerability and adaptation patterns among the study’s coastal communities, which can provide accelerated learning mechanisms to other coastal regions, are highlighted. The social and ecological framework and the associated survey approach allow for future integration of local-level vulnerability data with ecological and oceanographic models.

- Description: The global accelerating loss of biodiversity is having immediate repercussions for ecosystems and human wellbeing, particularly in areas where people depend intimately on their natural environment for their livelihoods. Dovetailing this loss is the demise of local/traditional knowledge systems resulting from factors such as changing lifestyle and the transformation of local belief systems. While the importance of local ecological knowledge (LEK) for documentation of biodiversity and environmental change and development of management responses is well established, quantitative tools to analyze and systematically compare LEK are scarce. In this research, we analyze the complexity of local ecological knowledge used by respondents to classify locally-recognized marine species. We do so by applying a modified index of taxonomic distinctness to an ethnoichthyological classification in coastal communities in the Solomon Islands. In addition, we assess simple taxonomic diversity (richness in locally-recognized species names) by comparing taxonomies collected in 1992–1995 and 2014–2015. Results indicate that both endogenous (gender, age) and exogenous (proximity to market) factors have discernible effects on folk taxonomic knowledge in the region, with younger respondents and communities closer to a regional market center displaying a significantly lower richness of local species names. Folk taxonomic distinctness was significantly reduced closer to the regional market. The modified index of taxonomic distinctness applied in this research provides a useful tool to explore facets of local ecological knowledge in addition to simple richness of terms, and to compare across different regions and cultural backgrounds. Understanding changes in LEK is important because such knowledge enables communities who are highly dependent on living natural resources to harvest and manage resources more efficiently and also to detect and react to environmental change.

- Description: This review article synthesizes the authors' several decades of multidisciplinary natural and social science and applied marine resource management experience in the Asia-Pacific region to examine the strengthening of coastal and marine resource management and conservation using alliances between local communities and external institutions. The objective is to assist the design of resource management and conservation programs that enhance the capacity of coastal communities in Oceania to confront both diminishing marine resources and the effects of climate change by providing guidelines for protecting marine biodiversity and vulnerable ecosystem functions. This article describes a management framework that hybridizes local beliefs and institutions expressed in customary management (CM) with such modern management concepts as marine protected areas (MPAs) and ecosystem-based management (EBM). Hybrid management accommodates the social, political, economic, and cultural contexts of Oceanic communities and, compared with recent or conventional management approaches, can therefore better address fundamental local concerns such as coastal degradation, climate change, sea level rise, weak governance, corruption, limited resources and staff to manage and monitor marine resources, and increasing poverty. Research on the hybridization of management systems demonstrates opportunities to establish context-appropriate EBM and/or other managerial arrangements that include terrestrial and adjacent coastal-marine ecosystems. Formal and informal CM systems are widespread in Oceania and in some parts of Southeast Asia, and if appropriate strategies are employed rapid progress toward hybrid CM-EBM could be enabled.

- Description: This thesis aims to study the characteristics of traveling ionospheric disturbances (TIDs) as identified in the radar data of the South African National Antarctic Expedition (SANAE) Super Dual Auroral Radar Network (SuperDARN) radar located in Antarctica. For this project, 22 TIDs were identified from visual inspection of range time-intensity (RTI) plots of backscattered power and Doppler velocity parameters of the SANAE radar between 2005âAS2015. These events were studied to determine their characteristics and driving mechanisms. Where good quality data were available, the SANAE HF radar data were supplemented by Halley radar data, which has large area of overlapping field of view (FOV) with the SANAE radar, and also by GPS TEC data. This provided a multi-instrument data analysis of some TID events. Different spectral analysis methods, namely the multitaper method (MTM), Fast Fourier transform (FFT) and the Lomb-Scargle periodogram were used to obtain spectral information of the observed waves. The advantage of using multiple windowing in MTM over the traditional windowing method was illustrated using one of the TID events. In addition, the analytic signal of the wave from the MTM method was used to estimate the instantaneous phase velocity and propagation azimuth of the wave, which was able to track the change in the characteristics of the medium-scale TID (MSTID) efficiently throughout the duration of the event. This is a clear advantage over other windowing techniques. The energy contribution by this MSTID through Joule heating was estimated over the region where spectral analysis of both SANAE and Halley data showed it to be present. The majority of the TIDs (65.4%) could be classified as MSTIDs with periods of 20–60 minutes, velocities of 50–333 ms1 and wavelengths of 129–833 km. The TID occurrence rate was high around the March equinox with 12 out of the 16 event days being during March–May. March had a particularly high number of occurrences of TIDs (46%). The majority of the TIDs observed during this month propagated northward or southeastward. In terms of prevailing geomagnetic conditions, 6 out of 16 event days were geomagnetically quiet, while 10 occurred during geomagnetic storms and substorms. During quiet conditions, TIDs could be linked to Es and polarised electric fields in 2 of these events. The other quiet time events could not be related to Es instability and polarised electric field either because their exact propagation direction could not be determined or data quality from the Es region scatter was too poor to perform spectral analysis. The storm-/substorm-related TIDs are possibly generated through Joule heating, the Lorentz force and energetic particle precipitation. , Thesis (PhD) -- Faculty of Science, Physics and Electronics, 2022

- Description: This thesis aims to study the characteristics of traveling ionospheric disturbances (TIDs) as identified in the radar data of the South African National Antarctic Expedition (SANAE) Super Dual Auroral Radar Network (SuperDARN) radar located in Antarctica.

- Description: The synthesis, photophysical and photochemical properties of tetra- and chlorotetrapoly(oxyethylene)-substituted oxotitanium(IV) phthalocyanines are reported for the first time. The new compounds were characterized by elemental analysis, IR, 1H and 13C NMR spectroscopy, electronic spectroscopy and mass spectra. These complexes showed monomeric behaviour in solution. General trends are described for photodegredation, singlet oxygen, triplet state and fluorescence quantum yields, and triplet and fluorescence lifetimes of these compounds in dimethyl sulfoxide (DMSO). Photophysical and photochemical properties of phthalocyanine complexes are very useful for PDT applications. The complexes showed high triplet quantum yields and triplet lifetimes in DMSO. The singlet oxygen quantum yields (ΦΔ), which give an indication of the potential of the complexes as photosensitizers in applications where singlet oxygen is required (Type II mechanism), were 0.72 and 0.78 for 3a and 5a, respectively. Thus, these complexes show potential as Type II photosensitizers. These complexes were also quenched by benzoquinone for fluorescence quenching studies.

- Description: Synthesis of the water soluble zinc phthalocyanines (3, 4) obtained from the phthalonitriles substituted with oligo(ethyleneoxy)thia groups are described. The new compounds have been characterized by elemental analysis, IR, 1H and 13C NMR spectroscopy, including HSQC, HMBC and COSY bidimensional correlation techniques, electronic spectroscopy and mass spectra. The aggregation behaviour of the phthalocyanine compounds (3, 4) was investigated using UV–vis spectroscopy in dimethylsulphoxide. Photochemical and photophysical measurements were conducted on oligo(ethyleneoxy)thia appended zinc phthalocyanines. General trends are described for quantum yields of photodegredation, fluorescence yields, triplet lifetimes and triplet quantum yields as well as singlet oxygen quantum yields of these compounds. The phototoxicity against cancer cells of the new compounds was investigated during several in vitro experiments. The dye-sensitized photooxidation of 1,3-diphenylisobenzofurane via 1O2 was studied in dimethylsulphoxide.
