  • Description: Public health research highlights the influence of socio-political biases shaping obstacles to fair healthcare access based on gender. South Africa has shown commitment to resolving gender imbalances in healthcare, historically emphasizing cisgender women’s challenges. However, research gaps exist in exploring how public health systems perpetuate disparities among gender-diverse persons, like trans women, who face exclusion due to their deviation from cisgender norms in healthcare. Critical, intersectionality-informed health research carries the potential to reveal the diversity of gendered healthcare experiences and expose the systems and processes that marginalize trans patients.

  • Description: Investigating the concurrent impacts with harvesting on wild vegetables can guide their sustainable management while contributing to the understanding of such impacts on NTFP species. This study investigated leaf production, morphological and growth responses to the concurrent impacts of drought and leaf harvesting between two wild vegetables. A randomized greenhouse experiment was implemented with 1,334 plants of Amaranthus sp. and 391 of B. pilosa. A drought treatment was first implemented through six levels of drought stress and a control treatment. The harvesting treatment consisted of four harvesting levels and was implemented twice. Measurements were recorded before first and second harvests and at end of experiment. Data were separated into two periods (after first and second harvests) and analyzed using Multivariate Analysis of Variance and log-linear analysis. The results showed significant effects of drought on both species. However, Amaranthus sp. appeared more resilient to reduction in the daily amount of water than reduction in the frequency, while B. pilosa was resilient under both facets of drought stress. For Amaranthus sp., basal diameter, its growth, leaf production and survival increased with increase in the harvesting level (with some exceptions) after first harvest. After second harvest, there was decrease in plant height and leaf production. In B. pilosa, the impact was only significant on survival and leaf production (after first harvest). The effect of the interaction of the two drivers was significant for Amaranthus sp., but not for B. pilosa. The results also highlighted the possible negative impact of a prolonged high rate harvesting on the species performance, especially under severe drought. Basal diameter, its growth, survival and leaf production appeared more resilient to reduced amounts of watering in Amaranthus sp., and under both types of drought stress for B. pilosa. This suggests that both species could be sustained under medium drought stress.

  • Description: The study explored the implemention of inclusive education in primary schools in the uMgungundlovu area, in the province of KwaZulu-Natal, South Africa. Locally and globally, the notion of inclusive education has presented various difficulties relating to the understanding stakeholders have of inclusive education and also in terms of embracing it and implementing it in schools. Stakeholders in South Africa have experienced similar challenges regarding a clear and common understanding of inclusive education and ensuring effective implementation. Despite various reforms adopted by the South African government, learners experiencing barriers to learning have persistently suffered inadequate access to quality education and equal learning opportunities. The reviewed literature has highlighted numerous challenges that have constrained effective implementation of inclusive education in South African schools. The reviewed literature also indicated that some teachers had negative attitudes towards inclusive education, and that such attitudes were linked to the lack of clear understanding of what inclusive education was about. At the core of this study is the fact that very little is known in South Africa about the implementation of inclusive education. Therefore, this study sought to unravel how chools implement inclusive education and, in that process, contribute to a deeper understanding of this phenomenon. The study utilised the Theory of Planned Behaviour as a theoretical framework and inclusive pedagogy as a conceptual framework to explore the implementation of inclusive education in four study schools. A qualitative approach underpinned by an interpretive research paradigm was adopted. Purposive sampling techniques were used to select twenty educators, four learners experiencing barriers to learning and four parents of learners experiencing barriers to learning to participate in this study. Four techniques were used to produce qualitative data, namely, semi-structured interviews, observations, documents’ review, and focus group discussions. Semi-structured interviews with educators and learners experiencing barriers to learning were utilised to generate data in the four selected primary schools. In addition to semi structured interviews, learners were also observed during lessons. Relevant documents kept in the schools were also reviewed to augment data generated through interviews. Focus group discussions were held with four parents of the learners experiencing barriers to learning. Data were analysed employing qualitative content analysis to come up with themes. The findings revealed that there was no common understanding amongst the teachers about what constituted inclusive education. Most educators understood inclusive education as referring to accommodating all learners in the classroom to reach their potential. These educators would help all learners, including those with barriers to learning thus contributing to the implementation of inclusive education in their schools. However, the findings also revealed that some educators understood inclusive education as referring to a situation where all learners received quality education, but those with barriers to learning being accommodated in special schools or special classrooms separate from their counterparts. The findings indicated that there was a lack of knowledge about inclusive education and such a lack contributed to misunderstandings about the essence of inclusive education. In addition, teachers lacked skills in dealing with learners experiencing barriers to learning, resulting in inefficient and ineffective implementation of inclusive education. It was evident from the findings that the curriculum was inflexible and the teachers lacked capacity to customise the content to the needs of all the learners, especially those experiencing learning barriers. Therefore, for teachers to implement inclusive education, it was necessary that content had to be flexible to meet the educational needs of all learners. The findings further revealed that using various teaching methods, such as visual objects and demonstrations was helpful in adapting the rigid curriculum and making it user friendly for learners experiencing barriers to learning. In addition, the research findings revealed that group work and peer learning assisted educators to implement inclusive education. Research findings also revealed that implementing inclusive education was hindered by various systematic factors, such as lack of parental support, overcrowding in classrooms, and socioeconomic challenges. I concluded that there is a remarkable knowledge deficit that can be addressed by training, including pre-service and ongoing professional development activities for teachers. I can also conclude that based on the findings educators require training on inclusive education, beginning with teachers currently in the system. The training can then be included in the curriculum of pre-service educators so that they can obtain a clear understanding of inclusive education and thus develop positive attitudes towards inclusive education. Similarly, school management teams require training on their own so that they can be able to provide adequate and effective support to the teachers in the classrooms. Another recommendation is that educators should be capacitated and developed in inclusive education to enhance their confidence in delivering the curriculum and to handle learners experiencing barriers to learning. Similarly, it is recommended that there be a collaboration between schools, homes, and other stakeholders to assist learners experiencing barriers to learning on their education journey, thus effectively implementing inclusive education in schools. Finally, a model for the improvement of inclusive education is proposed. , Thesis (PhD) -- Faculty of Education, 2023

  • Description: Interspecific and intraspecific diversity are essential components of biodiversity with far-reaching implications for ecosystem function and service provision. Importantly, genotypic and phenotypic variation within a species can affect responses to anthropogenic pressures more than interspecific diversity. We investigated the effects of interspecific and intraspecific diversity on microplastic ingestion by two coexisting mussel species in South Africa, Mytilus galloprovincialis and Perna perna, the latter occurring as two genetic lineages.

  • Description: Global climate change is anticipated to be associated with changes in the salinity regimes of southern African estuaries as a result of the increased frequency of occurrences of extreme weather events (droughts and coastal storms) and the rise in sea level. The current investigation assessed the impact of salinity on the egg production rate (EPR) of the numerically important sac-spawning calanoid copepod, Pseudodiaptomus hessei, in a temporarily open/closed southern African estuary. The EPR of the copepod was determined using in vitro incubations during three distinct salinity regimes corresponding to the freshwater-deprived (hypersaline-salinity 38 PSU), freshwater-dominated (mesohaline-salinity 5 PSU), and polyhaline water phase (salinity 24 PSU).

  • Description: Cultural-historical activity theory (CHAT) research has established an impressive body of scholarship that advances social understanding of human agency in the transformation of society, much of which is captured in contributions to this volume (cf. Hopwood (Chapter 15); Sannino (Chapter 2); Stetsenko (Chapter 3); Bal and Bird Bear (Chapter 8)). The main tenets of this work, building on the historical legacy of Vygotsky and Marx, affirm that humans are not passive recipients of external stimuli or influences but are active co-creators of the world (s) they inhabit. They are capable of using and producing cultural tools to take power over their own volitional action (s)(cf. Sannino, 2015, Chap-ter 2 of this volume; Hopwood and Gottshalk, 2017). Vygotsky’s major legacy in coming to understand transformative agency is that the cultural tools produced and used as mediational means are critical in the emergence of transformative agency (Sannino, 2015, 2020, Chapter 2 of this volume; Stetsenko, 2019; Hopwood, Chapter 15 of this volume) and thus in the transformation of human activity. As shown by Sannino (2015, 2020), such tools offer stimulus for volitional action that can break paralysis, especially when conflicts of motives are experienced.

  • Description: Discretionary accruals remain decade’s long measures to detect earnings management in empirical accounting research. The correctness of the specifications and test power of the information content for the models remains unexplored based on samples of most emerging market firms. Yet, country’s-based researchers have increasingly used different Jones-based discretionary accruals to proxy earnings management. The paper aims to evaluate four discretionary accruals models and to decide the most appropriate one for the detection of earnings management. For the aim, we apply regression methods to estimate and evaluate four Jones-type discretionary accruals models – simple Jones, modified Jones, extended Jones cash flow model and working capital accruals – based on evidence of a final sample of 1,852 firm-year of 102 firms in Nigeria during 2001–2020. The results disclose that all models are well-specified such that the likelihood of Type I errors is minimum and below the significance level of 5%. In order to demonstrate the power of the test, the simulations completed identify that the modified Jones model exhibits the highest power capability. The implication of this finding is that the modified Jones model is the most appropriate model to detect earnings management based on the Nigerian sample.

  • Description: Regulatory authorities have to date utilised a strategic blend of fiscal and monetary policies in dealing with the unique set of macroeconomic conditions facing South Africa. Government policy intervention has significant implications for economic growth and output within the manufacturing environment. Heterogeneity has also been discerned in relation to the responsiveness of various industries within the manufacturing sector towards both fiscal and monetary policy variable variations. However, given weakened growth prospects, policy alignment issues have been observed. The purpose of this study was firstly, to examine the impact of fiscal and monetary variables on manufacturing sector output in South Africa and secondly, to analyse the manufacturing industry significance of the various monetary transmission mechanism channels. The study made use of quarterly and monthly data to achieve these stated objectives, dated between 1998 and 2020. To achieve the first objective, the study employed the Autoregressive Distributed Lag (ARDL) model given the order of integration of the variables. The empirical results revealed significant, positive relations between tax revenue, deficit financing, nominal effective exchange rate (NEER) and money supply (M3) for total manufacturing (LTOTAL). Contrastingly, there were negative links between LTOTAL, government spending and the lending rate. At a disaggregated industry level, there were positive relations with tax revenue in food and wood industries, although tax revenue was significantly negative for metals. Likewise, to LTOTAL, linkages with spending were significantly negative for wood and metal industries but positive for chemicals. Negative spending signage could be a result of crowding-out. For deficit financing, positive associations within chemicals did not conform to expectations. Similarly, to LTOTAL, wood and metal industries conformed to expectations of negative relations with the lending rate. In respect of the NEER in food and wood production, significant, positive links were established. Contrastingly, a negative linkage existed for chemical activities at the 5% level. Concerning M3 and akin to LTOTAL, the relation with metal industries was positive. However, negative findings for food and chemicals contradicted expectations, suggesting money supply was not efficiently utilised in managing monetary variables in the long-term. The second objective of the study focused on analysing manufacturing industry significance of the various monetary transmission mechanism channels. The Vector Error Correction Model (VECM) were employed to analyse the relationship between the variables. Impulse response and variance decomposition were also constructed to further trace which channel is more significant in influencing manufacturing output. The empirical results revealed that the interest rate channel occupied a relatively significant role in both LTOTAL and several selected manufacturing industries. Shocks accounted for 9.71%, 11.96% and 14.28% of the variance in LTOTAL, metal and chemical industries. The asset price channel also appeared relatively significant, with shocks to the FTSE/JSE all-share index explaining 18.21% and 21.13% of the variation in food and wood production, signifying the most relevant channel for these particular industries and representing the second most important channel for LTOTAL and the other remaining industries. The exchange rate channel also presented as being a more relevant channel for food and wood, but occupied little role in LTOTAL, whilst the credit channel was relatively ineffectual for both LTOTAL and all industries examined. The results obtained imply that government should exercise caution and demonstrate fiscal restraint and that the South African Reserve Bank (SARB) need to take greater consideration of output fluctuations in monetary policy setting. Research has dictated that an expansionary fiscal policy is generally required as a means to achieving increased growth. However, findings obtained at both the aggregate and disaggregated manufacturing level in South Africa largely varied. This implies significant heterogeneity within the South African manufacturing sector in respect of fiscal policy responses. Expansionary fiscal stimulus packages need to be better targeted towards industries that will most benefit. Similarly, monetary policy responses at the aggregate and disaggregated manufacturing level in South Africa were heterogeneous and furthermore, differed when examining combined policy impacts. There was also a heterogeneous response with respect to relevance of the channels, via which monetary policy operated, with the interest rate channel dominating. SARB do take into consideration output fluctuations in policy setting but this is not currently emphasised or legislated. , Thesis (DCom) -- Faculty of Management and Commerce, 2023

  • Description: Several components of classical biological control (CBC) programmes are necessary to assess the success of the management strategy (e.g., post-release monitoring) and also help prevent reintroductions or resurgences of invasive species (e.g., public awareness). Water hyacinth, Pontederia (= Eichhornia) crassipes (Mart.) Solms (Pontederiaceae) is an aquatic plant naturally distributed in the north-eastern region of the Del Plata basin in Argentina. In the 1960s it was introduced into the Dique Los Sauces reservoir located outside of its native range in La Rioja Province, in western Argentina, where it became invasive. The natural enemy, Neochetina bruchi Hustache (Coleoptera: Curculionidae), was intentionally introduced in 1974 to control the weed. To assess the success of this CBC programme, a long-term post-release study was conducted. Between 1965 and 2023, we monitored plant coverage, estimated N. bruchi densities, and quantified the associated damage by reanalysing previously published data and incorporating new sampling. We also conducted an online survey to analyse public knowledge and perception about this programme. Water hyacinth coverage fluctuated from its first record in 1965 (maximum coverage 90%) until the control of germinated plants (coverage 0%) in 2018. The plant decline was accompanied by an increase in the weevil population. In our survey, out of 325 respondents only a small group of mostly middle-aged and elderly people knew that the restoration had been achieved through a management strategy and even fewer were aware of the biocontrol approach taken. Respondents who had a positive approach to biological control were more aware of the management plan than respondents who had neutral or negative opinions. Neochetina bruchi has played a key factor in the control of P. crassipes. The intrinsic dynamics of these populations, the dormant seed bank, and the lack of public awareness support the need for long post-release evaluations including outreach campaigns to make a sustainable successful management programme.

  • Description: This work focuses on the study of the effects of the ultrasonic frequency (MHz) and power (W.cm−2) on the stability, reactive oxygen species yields and cytotoxicity activities of differently substituted ionic phthalocyanines (Pcs) in sonodynamic therapy (SDT). Four ultrasonic parameters were investigated: Par I (1 MHz: 1 W.cm−2), Par II (1 MHz: 2 W.cm−2), Par III (3 MHz: 1 W.cm−2) and Par IV (3 MHz: 2 W.cm−2). A higher degradation of the Pcs was observed with increasing power at the Par II. Two reactive oxygen species (ROS) were detected in the ultrasound treated Pcs: singlet oxygen and hydroxyl radicals. Due to minimal degradation of most Pcs, Par I was chosen for SDT, photodynamic therapy (PDT), and photo-sonodynamic therapy (PSDT) against Michigan Cancer Foundation-7 and Henrietta Lacks cancer cell lines. PSDT generally showed improved therapeutic efficacies of the Pcs compared to the SDT and PDT mono treatments.

  • Description: Small businesses play an important role in the growth and success of local economies worldwide. Regrettably, the persistent issue of small business failure stems from external and internal challenges. One of the most important internal challenges is the lack of knowledge required to configure a small business to sustain performance in a dynamic environment. The business's dynamic capabilities and human resource management are vital aspects. This study investigated the mediating role of knowledge-based dynamic capabilities in the relationship between human resource management practices in small businesses, using the AMO framework, and small business performance. The research employed a quantitative approach, utilising convenience and snowball sampling techniques. It yielded valid responses from 231 small businesses in the Eastern Cape region. Statistical analysis was conducted using SPSS version 27 and AMOS version 22. The relationships were tested using the Person correlation coefficient, while simple regression models were used to test the influence of the variables within the study hypotheses. To examine the mediating effect, the Hayes Process Macro was utilised. The analysis unveiled positive and significant relationships between human resource management practices and knowledge-based dynamic capabilities with performance in small businesses. Knowledge-based dynamic capabilities and all its subcomponents also mediated the relationship between all dimensions of small business human resource management practices and performance. The implication of these findings highlights the urgent attention small businesses should give towards human resource management practices and building knowledge-based dynamic capabilities. These findings also alert policymakers and small business managers to what aspects of human resource management practices and knowledge-based dynamic capabilities should be prioritised for optimal performance in small businesses. , Thesis (MBM) -- Faculty of Management and Commerce, 2023

  • Description: Competition and access to financial services are lauded as key ingredients in the fight against poverty. While competition enhances markets, fosters innovation, productivity and growth, financial inclusion allows the poor to save, access credit and insurance thereby allowing them to meaningfully contribute to economic growth and also smooth their consumption. Moreover, competition reduces the cost of finance, thereby further expanding the availability of financial services. This suggests an important relationship between competition in the banking sector and financial inclusion. Research in this area is still in its infancy and little consensus exists on both whether the relationship is a robust one or not. There is no unanimity on the direction of causality or whether competition in the financial sector is good or bad for markets. This study examines the nexus between banking competition and financial inclusion in Upper-middle income countries. It employed a panel data set over the period 2011-2017 and Generalized Methods of Moments technique was employed to answer this enquiry. The findings of this study suggest that market power is not bad for financial inclusion in upper-middle income countries. Moreover, the study found that bank competition does not matter in banking the unbanked population in Upper-middle income countries. The implication of the findings of this study is that the focus of the policy makers should not be on policies that reduces concentration and market power in the banking sector, but be on measures that encourages contestability. The threat of entry is sufficient to make banks behave in a competitive manner. , Thesis (PhD) -- Faculty of Management and Commerce, 2023

  • Description: The digital gap has been hitting rural schools across the world. This has also been witnessed in South Africa. This digital gap is a result of inequality amongst households. Hence, learners and teachers from rural schools cannot access technologies as urban learners and teachers do. This situation has caused a lack of connectivity, lack of information about ICT, lack of resources, and lack of skilled teachers in rural schools. Globally, almost all countries have shifted to do things online. However, some countries struggled to shift successfully such as India. The introduction of elearning in South African government schools was done with the aim of improving results performance and to develop skills in learners and allow a flexible learning environment. In some urban and semi-urban areas, teachers are able to use new technologies to teach; however, rural teachers are bound to use traditional teaching only. The problem actually surfaced when the new pandemic known as COVID-19 started in Wuhan, China, in 2019 and spread across the world. This also affected the South African education systems, where teachers and learners were ordered to stay away from school premises and institutions, as way of preventing the virus from spreading. Rural teachers could not perform any academic activities, like urban schools did, to reach out to their learners as they wished because of the challenges stated above. Using e-learning during the 2020 pandemic was an unending nightmare for these rural teachers as they faced more challenges than those that had existed prior to COVID-19. The identified challenges discussed in this paper are those that were experienced by Alfred Nzo district teachers. This paper also refers to how e-learning was used by these teachers. Challenges identified in the literature were addressed through guidance of the UTUAT model which was adopted for the study. Each problem was categorised in line with UTUAT model four construct. The two branches of philosophies were brought in which are ontology and epistemology. Ontology asks question about the reality or existence of something and epistemology asks question about proving he existence of something. This study adopted the qualitative approach and followed that approach in terms of research paradigm, data sampling, data collection and analysis and techniques. Interviews were conducted with 15 teachers (teachers, head of department, school principal and subject advisor) from high and primary school levels, after the consent forms had been issued to obtain permission to proceed with interviews. Notes and audio recordings were made use of during interview sessions for data analysis purposes, with NVivo being used to analyse the data. Form the issues identified, these are the themes that were created which are:poor understanding of the concept “e-learning” by rural educators, high levels of resistance from educators, pedagogy of educators, insufficient support of the concept “e-learning”, poor implementation of e-learning. Lastly, after the data had been collected and analysed, this study developed five new success factors that should be implemented by the Department of Basic Education (DBE) to address issues identified as themes after thorough analysis of the literature and interviews. , Thesis (MIS) -- Faculty of Management and Commerce, 2023

  • Description: Invasive alien plant species (IAPS) frequently offer both ecosystem services and disservices to rural communities with high livelihood dependency on local landscapes. However, biocultural relationships with IAPS may go deeper than just provisioning uses, as they may be assimilated into local belief systems manifest in them becoming embedded in cultural constructions such as naming, stories, songs and ceremonies. It is likely that IAPS that are culturally assimilated will represent a greater conflict of interest in the face of proposed controls of IAPS in biodiversity hotspots where conservation priorities are frequently deemed paramount by external agencies. Using a mixed-methods approach we undertook roadside surveys of 17 selected IAPS along the 250 km Wild Coast section of the Maputaland-Pondoland-Albany biodiversity hotspot, accompanied by questionnaire interviews with 48 local people. The mean number of IAPS per site was four, ranging from zero (only one site) to ten, and local inhabitants deemed the abundance of all but one of the species to be increasing. All species had been in the region for decades, had a vernacular name, and all but one had direct consumptive uses. Species with multiple uses were more widely recognised. However, there was only marginal incorporation of the IAPS into stories, songs and ceremonies, although medicinal uses of some IAPS were for cultural/spiritual needs rather than physical ailments per se. These results show that despite widespread use, there was as yet relatively limited cultural assimilation of the IAPS in the Wild Coast region.

The investigation utilises the Theory of Planned Behaviour and the Security Behaviour Intentions Scale to examine the attitudes, intentions, and actual usage patterns of High-Performance Computing Systems among students and staff members. Following the positivism paradigm, this study formulated hypotheses aimed at achieving the objectives. The research sample comprised of 306 users of High-Performance Computing systems selected through the convenience sampling. Employing a quantitative approach, the study used a crosssectional survey research design to collect and analyse data to achieve the study's objectives. The study's findings revealed a significant negative relationship between risky cybersecurity behaviours and attitudes toward High-Performance Computing Systems, highlighting the adverse impact of such behaviours on users' perceptions and acceptance of these systems. However, an insignificant relationship was found between attitudes toward High-Performance Computing Systems and the intention to use them. This suggests that attitudes alone may not substantially influence user behaviour in this context, contradicting the initially proposed relationship. Furthermore, the investigation identified an insignificant correlation between the intention to use High-Performance Computing Systems and the actual utilization of these systems, indicating a gap between intention and behaviour. This implies that the study's hypothesized relationship between these latent variables was not supported. Lastly, a noteworthy correlation emerged between social influence and the effective use of High- Performance Computing Systems, supporting the relationship between these variables. In summary, this research significantly enhances comprehension of the challenges and repercussions associated with cybersecurity behaviour in adopting and utilising High- Performance Computing Systems across five South African Historically Disadvantaged Institutions. It underscores the importance of addressing risky behaviours, enhancing user education, and implementing secure systems. These actions are essential for fostering the effective utilisation of High-Performance Computing Systems and unlocking their potential benefits for economic growth and educational advancements in South Africa. , Thesis (MIS) -- Faculty of Management and Commerce, 2023

  • Description: In this chapter, we focus particularly on the mediating role of the university, in close connection with vocational institutions and informal community actors, in developing an inclusive approach to vocational education and training (VET) through an expanded social ecosystem for skills model. Here we draw upon lessons learnt from the Alice and Gulu cases on communitybased approaches to establishing an expanded skills ecosystem approach to VET in Africa. The main ques-tion guiding this chapter relates to the possible mediating role of the university to enhance a regional expanded ecosystem for supporting quality vocational education that is also rele-vant to its context, including emergent possibilities to build skills and livelihoods linked to just transitions. Universities are not VET centres as conventionally understood, but they can contribute to VET in various ways. Most often, universities are identified as contributing to the qualifications and training of VET educators. In this chapter, we take a different angle and consider the role of engaged research and community engagement as two approaches that can contribute to the advancement of an expanded social ecosystem model with positive benefits for VET institutions. Drawing on insights gained in the earlier chapters of this book requires us to take into account several important realities as previously dis-cussed, as well as key ingredients for the development of a regional skills ecosystem of vocational education, as demon-strated by the two cases considered in this chapter.

  • Description: It has been argued that V-stranding VP ellipsis exists in Bantu languages such as Kiswahili, Ndendeule, Chingoni, Kikuyu and Shingazidja. In the derivation, the verb moves to I0 in a tensed clause and thus survives VP ellipsis. However, through an examination of the components of a VP and their syntactic positions, we demonstrate that isiXhosa does not have V-stranding VP ellipsis. The article shows that VP-internal constituents – including object DPs, VP-internal adverbials and locative arguments – are prohibited from being elided and that the constituents that can be deleted are actually dislocated to a VP-external position before VPE takes place. We further examine the reasons why isiXhosa does not have V-stranding VP ellipsis and find that in the conjoint form the Immediately After Verb (IAV) constituent receives a focus reading, whereas in the disjoint form, it is the verb that receives a focus reading, which suggests that the VP does not comply with the e-GIVENNESS condition. We also explore the properties of the missing object and conclude that the missing object DP is a consequence of PF-deletion.

  • Description: The study was carried out to investigate the training of pre-service Science teachers in the integration of Information and Communication Technology (ICT) in Science teaching at two colleges of education in the Volta region of Ghana. The study aimed to recommend a framework that can be used to enhance the training in ICT integration competencies of pre-service Science teachers at colleges of education in the country. The study was underpinned by two theoretical frameworks: Rogan and Grayson’s curriculum implementation framework and Guzman and Nussbaum’s ICT integration framework and was located within the interpretive paradigm. The qualitative research approach was adopted to generate data on the types of ICT integration competences that pre-service Science teachers are trained in, the pedagogical strategies used, the support provided, and the challenges faced during the training. The study adopted the explanatory case study design. Convenience and purposive sampling were used to select the study sites and participants respectively, which consisted of two teacher education colleges, two heads of Science department, ten lecturers, and 20 pre-service Science teachers. The study’s data collection methods were semi-structured face-to-face interviews with the lecturers, focus group discussions with the pre-service Science teachers, non-participatory lesson observation, and document analysis. The data was analysed using thematic approach. The study established that pre-service Science teachers at the two colleges received training in mastering the usage of ICT tools, relating ICT to teaching; using ICT for assessment and providing feedback, creating an appropriate environment for ICT integration, and developing positive attitudes toward ICT usage. The study revealed the pedagogical strategies used for training the pre-service Science teachers in ICT integration competencies to include a standalone ICT course, demonstration, group work, self-learning and how assessment is carried out. The study also established that there was support from both within and without the college environment in training pre-service Science teachers, although this was inadequate. The major challenges found by the study to be hindering effective pre-service teacher training in ICT integration competencies were lack of technical know-how among lecturers, poor pre-service Science teachers’ backgrounds in ICT, inadequate ICT resources and infrastructure, prolonged organisational and management bureaucracy, and insufficient funding of ICT. The recommendations made included the need for upgrading infrastructure in the colleges while also upgrading lecturers’ competencies in handling ICT in the colleges. An alternative training framework for preparing pre-service Science teachers in ICT integration competencies was also proposed. , Thesis (MEd) -- Faculty of Education, 2023

  • Description: The Knysna Estuary is a large, clear-water embayment and one of the most important estuaries for conservation in southern Africa. The estuary is detritus-dominated and the benthic food webs have low diversities of carnivores, which may make the estuary vulnerable to invasions through the empty niche hypothesis. In the last two decades, the Knysna Estuary has experienced an increase in the population of the cryptogenic and apparently omnivorous estuarine moonshine worm (Diopatra aciculata). Our goal was to describe the trophic role of D. aciculata. We measured carbon and nitrogen stable isotopes in all the common macrophytes and macroinvertebrates across four seasons to 1) establish the isotopic landscapes of three disparate sites within the Knysna Estuary where D. aciculata occurs, 2) establish whether the trophic level of D. aciculata matches those of other common macroinvertebrates, and 3) establish whether the isotopic niche of D. aciculata overlaps with those of syntopic macroinvertebrates. Communities at the different sites differed in food web width, most likely due to differences in primary producer diversity. Our findings suggested that D. aciculata is a facultative carnivore, and some sub-populations are sustained primarily by animal tissues. Isotopic niche overlap analysis showed that direct competition with other common macroinvertebrate consumers is doubtful and D. aciculata occupies a unique niche within the estuary.
