- Description: Studies of ethnicity have shifted from primordialism to diverse variants of social constructivism, which include instrumentalism, invention of tribalism by the colonial elite and missionaries and demotic constructivism or creation of ethnicity from below. The studies have generally generated two broad schools of thought. One school avers that African ethnicity was invented by the colonial elite and missionaries in the colonial period whilst the other and more recent asserts that ethnicity had a precolonial currency and the generality of Africans also played a key role in identity formation. Also most notable is that most studies have tended to focus on larger and more visible ethnic groups, ignoring the stories of small communities mostly found in remote border areas of modern ‘nation’ states. Using archival material, colonial records, autobiographies, oral and secondary sources, this thesis, which is largely guided by the demotic constructivist theoretical perspective examines the evolution of the ethnic identity of an ‘obscure’ Hlengwe ethnic community of the south-east lowveld of Zimbabwe from the pre-colonial period to 2014. History of the Hlengwe history has been blurred by the use of the term “Shangaan” to denote the Hlengwe, yet they were not ethnically so. A chronological approach and demotic constuctivism have been used to enable a deeper analysis of the critical historical phases, key players and processes in Hlengwe identity formation as time wore on. While we acknowledge that identity formation involves diverse players, we also focus on the role of the generally neglected commoners in the making of African ethnicity. This study differs from other works on ethnicity which focus on events of short historical phases and the role of selected elitist agents in the making of African ethnicity, by analysing the making of Hlengwe ethnicity from the precolonial to the postcolonial period. We prove that Hlengwe ethnicity was created in the pre-colonial period but did not remain static as it was perpetually reshaped by unpredictable historical events right up to 2014. The Hlengwe community was subjected to processes of social transformation over a long period of time to an extent that the one time docile, ‘uncivilised”, inward looking community bearing an identity of shame had evolved by the close of the 20th century and early 21st century to an assertive community, proud of its identity and actively seeking political, economic and cultural recognition and rights for its ‘underdog’ Hlengwe constituency in a country where diverse Shona groups andNdebele form the dominant ethnic communities.

- Description: The topic of social cash transfers is often viewed with scepticism. In the context of fragile states, questions of misuse, inaccessibility of social services, dependency and sustainability are often raised. This study sought to examine the transformative potential of social cash transfers on child wellbeing in fragile contexts through a case study of the social cash transfer pilot scheme in Bomi County of Liberia. The study specifically set out to to assess the relevance of cash transfers in the context of child wellbeing; determine how the wellbeing of child recipients of cash transfers had transformed; and analyse the determinants of the transformative effects of cash transfers on child wellbeing. The study adopted a quasi-experimental, mixed method, and cross-sectional research design. It utilised existing household survey datasets of the mid term and end term evaluations of the Bomi County pilot social cash transfer scheme conducted in Liberia in 2012 and 2015 respectively. A sample size of 224 (about 12percent of the sample frame) was used where Confidence Level was 95percent and P=0.5. This sample size was divided equally between households receiving cash (experimental group) and households with the same characteristics although not receiving cash transfers (control group). For the qualitative method, 66 participants were purposively sampled. A total of 34 participants participated in the indepth interviews, 32 children were sampled for focus group discussions. These were divided into 16 children from the experimental group and 16 children from the control group. Quantitative data sets were analysed in Statistical Package for Social Sciences (SPSS), and qualitative data was analysed through thematic analysis. The findings from the study provide a persuasive case for the transformative potential of social protection in fragile contexts. The study confirms the relevance of social cash transfers in promoting child wellbeing through empowering families to address children‘s physical and dependency-related vulnerabilities and institutional disadvantage. The study also confirms the transformative effects of social cash transfers on child health, food consumption, education, housing conditions, household assets, and child labour. In addition, the results indicate that social cash transfers mitigated gender based institutionalised disadvantage, created safe and protective environments for children and positively impacted on the local economy. However, the study also showed that, to a limited extent, social cash transfers had unintended impacts, particularly increase in child labour, where children were requested to sell in family petty businesses, and instances in which recipients misused the cash. The transformative effects of social cash transfers on child wellbeing were dependent on the size of the transfer, priorities in the use of cash, decision-making dynamics, and fairness of the selection process. The study proffers a Child Sensitive Transformative Social Cash Transfer Model based on the determinants of the impact of social cash transfer. The study ends by highlighting the critical role of social protection in infusing a transformative dimension to social work practice in fragile contexts, with a view to addressing equity, gender equality and child rights through confronting child vulnerabilities and institutionalised disadvantage.

- Description: Environmental assessments using bioindicators gain value if the interpretability of the indicator used is high, and it is clear how survey methods affect survey comparisons. Because dung beetles are favoured as bioindicators, we studied the trophic preference of a southern African beetle community and its potential effects on surveys of beetle diversity using manual sampling of droppings and pitfall traps baited with carnivore, ruminant or nonruminant dung. Manual sampling showed no significant differences between dung types in either dung beetles abundance or species richness. Generalised linear mixed models of total and endocoprid abundances, species richness and Real Shannon index of trap samples showed higher dung beetle diversity associated with ruminant than with nonruminant dung, which in turn was significantly preferred over carnivore dung.

- Description: Knowledge of trophic ecology underpins conservation and management of threatened species. Stable isotope analysis has been widely used as a more objective approach for elucidating the trophic positions of freshwater fishes. Until recently, stable isotope analysis for trophic ecology studies in freshwater fishes largely utilised white muscle tissue. This sampling approach, however, involves either euthanasia or muscle biopsy procedures that may be inappropriate for small-sized and endangered fishes. These concerns raised the need to explore and validate the utility of non-lethal alternatives such as fin clips, mucus and scales. The present study investigated the use of caudal fin tissue as a potential non-lethal alternative to muscle tissue for trophic studies on the chubbyhead barb Enteromius anoplus. The chubbyhead barb was selected as a model taxon for the present study because it is closely related or comparable in body size to a number of highly threatened small-bodied minnows in southern Africa. The chubbyhead barb was also considered an ideal species for this study because it is widespread, abundant and classified as Least Concern on the IUCN list of threatened species. The study used a two-pronged approach based on laboratory and field experiments. A laboratory experiment was conducted to quantify isotopic turnover rates and diet-tissue discrimination factors (DTDFs/A) for both muscle and fin tissues. This involved feeding chubbyhead barb two diets with distinct carbon (δ13C) and nitrogen (δ15N) values, and monitoring the temporal isotopic incorporation patterns into the two tissues. These patterns were assessed by applying least squares non-linear one- and two-compartment isotopic kinetics models. Model comparisons, based on Akaike information criterion (AIC), revealed that one- compartment models described isotopic incorporation patterns better than two-compartment models for both muscle and fin tissues. For δ13C, relatively short and comparable turnover rates were observed for muscle and fin tissues, which suggests that fin tissue could potentially provide similar inference as muscle tissue when assessing short term dietary patterns for chubbyhead barb. In contrast to δ13C, turnover rates for δ15N between muscle and fin tissue were different for both diets. Specifically, stable isotope incorporation turnover rate was faster in muscle tissue for animals that were fed on isotopically enriched diets compared to fin tissue. Conversely, stable isotope incorporation into fin tissue was faster in animals fed on isotopically depleted diets compared to muscle tissue. This suggests that knowledge of animal diet is critical when inferring fin tissue δ15N turnover rates, particularly when extrapolating both short and long term dietary patterns. Diet-tissue discrimination factors were influenced by diet type, with the fish fed on isotopically enriched diet having lower DTDFs than animals fed on isotopically depleted diets. This variation may be explained by the protein quality hypothesis, which suggests that the DTDFs of consumers will decrease as protein quality increases. When A13C and A15N values were averaged across diets in muscle and fin tissue, the values were 0.74‰ and 0.64‰, respectively, for A13C, and 5.53‰ and 5.83 ‰, respectively, for A15N. This appeared to be consistent with studies on other taxa for A13C (0-1 ‰), but for A15N (3-5 ‰) the results of this study were higher than those reported for other taxa. These results suggest that investigating appropriate DTDFs for both muscle and fin tissues is important in trophic ecology studies of these minnows. A field-based study was conducted to investigate temporal dynamics in food web patterns for chubbyhead barb in the wild within the headwaters of the Koonap River, a tributary of the Great Fish River, in the Eastern Cape, South Africa. This was achieved by collecting and comparing stable isotope data for chubbyhead barb and its potential food sources on a seasonal scale. There was a discernible difference in both the composition of carbon and nitrogen isotope values for basal food sources and macroinvertebrate communities, which suggests that this headwater stream was subject to temporal changes in food web dynamics. For chubbyhead barb, comparison of its isotopic niche sizes on a temporal scale based on both muscle and fin tissue showed differences across seasons. Furthermore, isotopic niche sizes inferred from fin tissue were larger than those inferred from muscle tissue during winter and spring, whereas during summer and autumn the isotopic niche sizes inferred from muscle and fin tissue were generally comparable. This suggests the likely influence of different metabolic and physiological processes that these two tissues undergo on a temporal scale. Therefore, difference in tissue type, and their associated metabolic pathways should be considered when using fin tissue as a substitute for muscle tissue on broad temporal scales. The results from this study indicated that caudal fin tissue has the potential to be a substitute for muscle in trophic studies of chubbyhead barb Enteromius anoplus, as well as other related small bodied endangered minnow species from South Africa.

- Description: Water availability is one of the major societal issues facing the world. The ability to understand and quantify the impact of key hydrological processes on the availability of water resources is therefore integral to ensuring equitable and sustainable resource management. A review of previous hydrological studies conducted in the Limpopo River Basin has revealed a gap in the understanding of surface water-groundwater interactions, particularly channel transmission loss processes. These earlier studies, focused largely on the Limpopo River’s main stem, have attributed the existence of these streamflow losses to the presence of significant alluvial aquifers and indicated that the losses account for about 30 percent (or 1000 Mm3 a-1) of the basin’s water balance. The work conducted in this dissertation reports on the delineation of alluvial aquifers across three sub-basins of the Limpopo River Basin namely, the Mokolo (South Africa), Motloutse (Botswana) and Mzingwane (Zimbabwe) sub-basins and the estimation of potential channel transmission losses based on the alluvial aquifer properties. Additionally, an assessment of the different approaches that can be applied to simulate these channel transmission losses in the Pitman Model is presented. To delineate alluvial aquifers, general land cover classes including alluvial aquifers were produced from Landsat-8 imagery through image classification. The areal extent of the delineated alluvial aquifers was calculated using ArcMap 10.3. To quantify channel transmission losses and determine the effects on regional water resources, three approaches using the Pitman model were applied. The three approaches include an explicit transmission loss function, the use of a wetland function to represent channel-floodplain storage exchanges and the use of a ‘dummy’ reservoir to represent floodplain storage and evapotranspiration losses. Results indicate that all three approaches were able to simulate channel transmission losses, although with differing magnitudes. Observed monthly flow data were used to as a means of validating loss simulations however for each sub-basin, medium and low flows were over-simulated which accounts for water uses that were inefficiently represented due to lack of data. Knowledge of the structure of the transmission loss function dictates that it is better at representing the dynamics of channel transmission losses, as it takes into account the contribution of losses to groundwater recharge whereas the other two functions simply store water and release it back to the channel. Overall, the hydrological modelling results demonstrate the potential of each approach in reproducing the dynamics of channel transmission losses between channel and alluvial aquifer within an existing sub-basin scale hydrological model. It is believed that better quantification of losses and more efficient qualitative determination of the function which best represents transmission losses, can be attained with more reliable observed data. In conclusion, a study of this nature can be beneficial to water resource estimation programmes as it highlights the uncertainties related with quantifying channel transmission loss processes in a semi-arid environment.

- Description: The significance of environment and sustainability education research and practice, and its potential contribution to a sustainable future for humanity, is conveyed by the International Social Science Council (n.d.), which explains: People everywhere will need to learn how to create new forms of human activity and new social systems that are more sustainable and socially just. However, we have limited knowledge about the type of learning that creates such change, how such learning emerges, or how it can be scaled-up to create transformations at many levels.Here, the important shift is towards considering what social systems, forms of knowledge, learning processes and questions of justice are associated with perpetuating or halting the decline of Earth’s bio-geo-chemical systems. This edition of the Southern African Journal of Environmental Education contributes three research papers and a themed Think Piece collection to these international deliberations about the role of education in enabling transformations to sustainability. Collectively, the articles highlight how relationality and the formation of human agency in socio-cultural and material settings in past–present–future configurations underpin all environment-oriented learning processes. The three research papers constituting the first part of this volume offer glimpses into how current unsustainable socio-cultural and material configurations might be transformed to address social inequalities and damaged people–nature relations. The Think Piece collection, introduced by Lotz-Sisitka, Læssøe and Jørgensen later in this editorial, focuses on how learning can foster and contribute to the development of change agents and collective agency for climate-resilient development.

However, we have limited knowledge about the type of learning that creates such change, how such learning emerges, or how it can be scaled-up to create transformations at many levels.Here, the important shift is towards considering what social systems, forms of knowledge, learning processes and questions of justice are associated with perpetuating or halting the decline of Earth’s bio-geo-chemical systems. This edition of the Southern African Journal of Environmental Education contributes three research papers and a themed Think Piece collection to these international deliberations about the role of education in enabling transformations to sustainability. Collectively, the articles highlight how relationality and the formation of human agency in socio-cultural and material settings in past–present–future configurations underpin all environment-oriented learning processes. The three research papers constituting the first part of this volume offer glimpses into how current unsustainable socio-cultural and material configurations might be transformed to address social inequalities and damaged people–nature relations. The Think Piece collection, introduced by Lotz-Sisitka, Læssøe and Jørgensen later in this editorial, focuses on how learning can foster and contribute to the development of change agents and collective agency for climate-resilient development.

- Description: Globally, unlike in the past, it is rare for a patient to consult the same healthcare provider throughout his or her lifetime. However, this makes it difficult to maintain informational continuity of care. Researchers have confirmed that paper-based methods of record keeping do not meet the needs of informational continuity of care. As a result, the popularity of electronic means of recordkeeping, specifically, electronic medical records (EMRs), is growing. However, the implementation of EMRs in hospitals is not without challenges with these challenges playing a significant role in the failure of EMRs. One such challenge is a lack of user acceptance. Research reveals that nurses comprise the largest user group of EMRs in the hospital setting. However, there is inadequate literature that focuses on the factors contributing to EMR acceptance with nurses as the user group. Hence, the main problem addressed in this research study relates to the inadequate understanding of the factors that influence the acceptance of EMRs by nurses. In order to address this problem, a literature review and a case study were conducted to ascertain and investigate the factors that influence the acceptance of EMRs by nurses. A total of 39 factors were formulated. Subsequent to the formulation of these factors, knowledge on the impact of each factor on EMR acceptance was collected. Socio-technical Systems Theory (STS) was used as a theoretical lens through which to view the resulting factors. The STS dimension from which each factor originates as well as the STS dimension influenced by the factor were identified. The analysis of the different stages of acceptance as well as the STS analysis resulted in a framework that could play an important role in providing a better understanding of EMR acceptance by nurses in hospitals. It was anticipated that this study would contribute to a better understanding of the factors that hospitals should address in order to create a conducive environment for EMR acceptance by nurses within the hospitals.

- Description: The main objective of the thesis is to understand the ongoing support for the African National Congress (ANC) amongst the urban poor in national elections in South Africa with specific reference to Queenstown. The study involved 50 residents in Mlungisi in Queenstown, the vast majority of whom are shack dwellers. The use of semi-structured interviews allowed for an indepth understanding of why people vote for the ANC. The research participants have always voted for the ANC and have no intentions of voting for any other political party. Since 1994, the ANC has in the main pursued a neo-liberal project with a limited focus on redistribution. Because of this, most blacks living in urban areas continue to live under conditions of extreme poverty. The abject material conditions of people living in Mlungisi does not provide a strong basis for why they would vote almost unreservedly for the ANC. In seeking to offer an explanation, the thesis turns to theories of the post-colony, including the work of Frantz Fanon and Partha Chatterjee, as these theories provide an analysis of the character of the post-colonial state and the ways in which the government engages with its citizens. These macro-level theories are complemented by middle-level theories about voting and voting patterns in seeking to understand why Mlungisi residents vote for the ANC, raising questions of identity, loyalty and clientelism in the process.

- Description: The focus of this study is to understand the contribution third space theory makes to literacy practices in the Masikhulisane Reading Programme. The Masikhulisane Reading Programme is an in-school reading club involving reading stories for enjoyment. This study concentrated on the Grade Six participants in term three of the programme, where cross-age reading receives emphasis in service of cultivating reading for pleasure. An older (or more experienced) learner was paired with a younger (less competent) learner for the purpose of nurturing quality reading competencies and reading for enjoyment. The challenges of bilingual reading and developing reading practices without sufficient resources informed this study. The Masikhulisane Reading Programme seems to provide a solution to some of these challenges, offering reading material to learners and affording them agency in terms of their buddy system. Multiple data generation methods were used in order to gain a real understanding of what the Masikhulisane Reading Programme meant to the Grade Six learners, namely: observation of classroom practice, drawings with written and verbal descriptions, and two teacher interviews. The teachers corroborated what the learners said, supporting the idea that learners benefit from an abundance of opportunities to read, while taking ownership in their paired reading. The framework designed for data analysis provided a type of coding, and a way of recognising themes. The designed framework provided an overview and was applied to all the data as a means of drawing out patters to provide explanatory potential. One way to understanding this programme is through the, Third Space Theory, which recognises that in different spaces, participants can take up different positions, allowing for different ways of being. Each Grade Six learners became the teachers with one buddy, teaching and establishing a reading practice with their younger buddy. This gave them the chance to be responsible for developing a love for reading, which was empowering for both them and their buddy.

- Description: There is an increasing call for conservation programmes to provide sound evidence of effectiveness, and employing empirical evaluations can assist in the transition to evidence-based conservation practices. The objectives of this research were to develop a logic model for the CapeNature Stewardship Programme which would articulate the programme's theory of operation with respect to its Stewardship Programme landholders. The second major objective was to develop psychometric instruments for assessing the motivations and satisfactions of the programme's stewardship landholders. Both objectives included the aim to provide robust and repeatable instruments for exploring landholder's psychology, and developing a programme's theory of operation to understand the programme and improve with understanding the needs of the landowners. In this regard the processes and methodologies employed represent a major component of this research. A mixed methods approach was utilized, including stakeholder and volunteer surveys, conducted via mailing hardcopies and the internet, together with three focus groups held with the programme's management, extension staff and the stewardship landholders. Analysis of the data thus collected included both qualitative and quantitative approaches, specifically coding and content analysis, together with statistical tests of internal consistency, factor analysis and doubling correspondence analysis. Robust indices for example validity and internal consistency were developed for assessing landholder’s satisfaction with extension and level of satisfaction with the stewardship programme (Babbie 2007). These indices revealed that landholders in the Stewardship Programme are not satisfied with the programme, and exhibit behaviours suggesting they act as advocates for the programme. Demographic data and additional information provided further insights into the programme. The development of a method for articulating the programme's theory of operation is represented, together with four logic models which graphically illustrate this theory. This process and theory allowed for recommendations to be provided for the programme's improvement. A platform for adaptive management and further evaluations of this, and similar programmes, represents a major outcome of this research, understanding the extension capacity needs for the conservation of biodiversity in the CapeNature Stewardship Programme to function as a model for improving the implementation of the programme across the Western Cape, South Africa. This research feeds into an evaluation of CapeNature’s Biodiveristy Stewardship programme and demonstrates the importance of incorporating psychology into conservation interventions.

Understanding the impacts of foliar insect pests on eucalyptus species growth and the development of appropriate management strategies

- Description: Within South Africa (SA), eucalypts contribute significantly to the commercial production of pulpwood, treated poles, wood chips and saw timber. Due to their rapid growth and desirable timber properties, 47% of the afforested area within SA is planted with various eucalypts and their hybrid combinations. Biotic and abiotic factors pose a risk to the productivity of eucalypts, with the most significant risk currently associated with the increased impacts of foliar insect pests on tree productivity, for example Leptocybe invasa Fisher & La Salle (Hymenoptera: Eulophidae); Gonipterus scutellatus Gyllenhal (Coleoptera; Curculionidae); Thaumastocoris peregrinus Carpintero and Dellape (Hemiptera: Thaumastocoridae); Glycaspis brimblecombei Moore (Hemiptera: Psyllidae) etc. Past and current research has focused more on the individual components of biological, cultural and chemical control, with limited research conducted on the practical integration of these management strategies. Although the combination of biological and cultural control methods for long-term management would be preferred, the use of environmentally acceptable insecticides can contribute to the short-term management of insect pests where necessary. Environmental constraints (associated with forest certification) around the use of insecticides, means that there are currently few insecticides available for controlling foliar insect pests of eucalypts within the SA forest industry. Due to the recent increased introduction of insect pests, there is also a lack of data related to their impacts on tree growth, as well as the success of any management methods used. To improve our understanding regarding these components, three groups of trials (five in total) were implemented in the summer rainfall region of SA to quantify the impacts of insect pests on eucalypt growth, test integrated management practices (chemical and cultural management), and test environmentally acceptable insecticides. In 2010, two insect exclusion trials were established at Palm Ridge and Teza plantations in KwaZulu-Natal to quantify the impact of insect pests on two Eucalyptus hybrids. The trial locations were selected adjacent to compartments for which the pests Gonipterus spp. and Thaumastocoris peregrinus were present. Each trial had an insecticide treatment with an active ingredient of alpha-cypermethrin at a rate of 100 g l-1 and a control treatment where trees were not sprayed. Insect pests were collected after every spraying event. A greater number of insect pests were collected from the Palm Ridge site. Gonipterus spp. were the predominant insect pests collected. No significant growth differences were recorded between treated and untreated trees at Teza. Measurements taken at Palm Ridge indicated that insecticide-treated trees had significantly greater tree growth than untreated trees. Final measurements showed a v 25% reduction in volume for the control treatment compared to the insecticide treatment. Results of this study indicate that timing and duration of insecticide application could hold larger and additive benefits for insect exclusion. Due to the lack of non-hazardous registered insecticides, and the susceptibility of many of the eucalypts grown within SA to L. invasa, a trial was initiated in 2011 in Zululand (KwaZulu-Natal). A 3 x 4 x 4 factorial combination of 48 treatments were replicated 3 trials and arranged in a split-split-plot design. The factors included insecticide type as the whole plot (fenvalerate, azadirachtin and imidacloprid), timing of insecticide application as a sub-plot (0, 3, 6 and 9 months) and type of hybrid as the sub-sub-plot (a susceptible and tolerant E. grandis x E. camaldulensis hybrid (GC_s and GC_t) and a susceptible and tolerant E. grandis x E. urophylla hybrid (GU_s and GU_t)). To determine insecticide efficacy, plots of untreated clones were included as control treatments within each replicate. The incidence and magnitude of L. invasa damage and tree performance were assessed for up to 5.5 years of age. L. invasa damage recorded over the trial period indicated that irrespective of treatment, damage was lower in the GU clones than the GC clones resulting in a 63.9 m3 ha-1 volume difference at 5.5 years. In addition, the difference between the GU_s and GU_t clones (3.2 m3 ha-1) was marginal when compared to the GC_s and GC_t clones (37.2 m3 ha-1). A decrease in GC stocking correlated with the period when there was a high damage incidence recorded for L. invasa. Although the three insecticides tested delayed the onset of L. invasa damage, they did not result in improved tree performance at 5.5 years. Results indicate that the planting of a tolerant species (hybrid in this trial) was the most viable option for the management of L. invasa. Two trials were implemented in the KwaZulu-Natal Midlands in October 2016 (at Ingwe and Balgowan plantations), to test the efficacy of eight different insecticides (synthetic and organic) for the management of foliar insect pests. The Ingwe trial was planted with Eucalyptus dunnii and the Balgowan trial was planted with Eucalyptus badjensis. The insecticides tested were azadirachtin, deltamethrin, imidacloprid (liquid and tablet), Beauveria bassiana, Bacillus thuringiensis, potassium silicate and a combination of plant oil extracts (garlic oil, soybean oil and capsicum oleoresin extract). The imidacloprid tablet, deltamethrin and an untreated control were implemented as additional treatments. The insecticides were tested at the recommended rate (single rate) and at double the recommended rate (double rate), except for the insecticides in the additional treatments which were only tested at the single rate. These insecticides were applied three times over a period of four months, and tree growth measurements (Gld/Dbh and Ht) were taken four times over a period of seven months. Gonipterus spp. vi was the only insect pest found in both these trials, thus the insecticides were tested for their efficacy in managing this specific insect pest. A higher population and damage of Gonipterus spp. was found in the E. dunnii trial and very little to no damage was observed in the E. badjensis trial. All insecticides tested were not effective in managing Gonipterus spp. in these specific sites. A low population of insect pests and incorrect timing and method of application of some of the insecticides could offer a plausible explanation of results. Results from these trials indicate that where foliar insect pests occur in high abundance, significant tree-growth reduction occurs. Although insecticides (deltamethrin - for G. scutellatus; imidacloprid for L. invasa) can be used for the short-term control of these insects, their commercial benefits may be reduced due to the number of repeat applications required and/or with high levels of infestation. Of the eight environmentally acceptable insecticides tested for foliar insect control, the low abundance of insect pests present in the trials meant that their efficacy could not be quantified. If an alternative insecticide were to be found, its application would need to be linked to the environmentally stimulated outbreaks of specific insects. Of the treatments implemented, the selection and planting of eucalypts with known resistance to specific insect pests currently remains the most viable management strategy. Breeding for increased tolerance within resistant eucalypts may also provide additional benefits. Although the above research showed the negative impacts of foliar insect pests on tree growth, it also indicated that no single control method is viable for all insect pests. Future research should look at the integration of different management methods while incorporating more insect pests and different seasons in the study.

Future research should look at the integration of different management methods while incorporating more insect pests and different seasons in the study.

- Description: The central focus of the study was to seek an understanding of the role that Social Capital plays in enhancing the resilience and adaptive capacity of the community to floods and droughts in Muzarabani District of Northern Zimbabwe. The study was conducted in two of the wards in Muzarabani District namely Chadereka and Kapembere. In addition, the study sought to understand the coping and adaptation strategies employed by the most vulnerable groups such as the elderly, child heads, women and single heads of households. The specific objectives of the study were: to understand the effects of floods and droughts on residents’ livelihoods and food security, examine residents’ perceptions on droughts andfloods and to document community-based strategies utilised by women, child-headed families and the elderly to improve their livelihood and food security in the face of floods and droughts, explore different types of Social Capital that exist in the study area especially with regard to household resilience to disasters, comprehend the basis of residents’ resilience to floods and droughts and the extent to which vulnerable groups rely on Social Capital when coping with these disasters and to examine the repercussions of residents’ strategies on the community’s institutional structures. The study was informed by Social Capital theory and the social network analysis. Social Capital plays a pivotal role in enhancing the resilience of the community to floods and droughts. Different types of Social Capital that exist and help people to deal with floods and droughts include linking, bonding, and bridging and victim Social Capital. Inhabitants within and outside villages support each other. Non-Governmental Organisations (NGOs) and the government are also working hand in hand with community members to reduce the negative impacts of floods and droughts. Volunteerism, generalised reciprocity and mutual understanding are also at the centre of interventions. The study employed both quantitative and qualitative approaches to achieve its objectives. Questionnaires, focus groups discussions, observations, transect walks, key informant interviews and some participatory methods were used to collect data. SPSS, content and thematic analysis were used to analyse data. The study found that floods and droughts negatively impact on human security, causing acute food shortages, intensifying poverty, spread of water related diseases, increasing divorce rates, children dropping out of school, reduced livestock and crop production, family disintegration, chaos in religion, exacerbating local unemployment as well as negatively affecting the wellbeing of community members. On a positive note, floods in Chadereka cause the deposition of alluvial soils that are good for crop production. However, in Kapembere, volunteerism is not very common; inhabitants are not yet trained about the concept. Community members have also formed cooperatives where they would give each other money or grain. In Chadereka, women have formed a mother-support-group to assist children with food in schools. Strategies being employed by the most vulnerable groups include casual labour, joining cooperatives, migration, taking children from school, hiring out cattle, selling of assets, riverine farming, growing drought-resistant crops, making use of indigenous knowledge systems, skipping meals and exploiting natural resources among others. Some women have resorted to prostitution to increase their resilience to floods and drought impacts such as poverty and acute food shortages. The elderly also hire out their cattle. They also rely on support from the government and NGOs. There are a number of challenges faced by residents in dealing with floods and droughts. Community social relationships, migration, casual labour and the sale of assets are the basis of the people’s resilience against the impacts of floods and droughts. The study identified the following issues which all stakeholders involved could take note of: the government should not always be suspicious of disaster-risk reduction strategies implemented by NGOs as this scares away some of them that are willing to offer untied or unconditional assistance; timely and impartial distribution of agricultural inputs to inhabitants would be extremely useful. Moreover, the government needs to provide resources that support local organisations (formed by the local people) to assist the most vulnerable people in communities. Community leaders, together with the government and NGOs, are encouraged to hold awareness campaign programmes that dispel tribal and ethnic stereotypes, to promote local Social Capital among members of the community. Further investigations in the following areas are critical: A more comprehensive assessment of the determinants of resilience to droughts and floods in Zimbabwe is necessary.A study on the challenges faced by the disabled people and women in polygamous marriages and how they are adapting to floods and droughts, needs to be conducted and a critical investigation on the Zimbabwean government’s strengths and weaknesses in enhancing the resilience of the community to floods and droughts is necessary among others.

- Description: This thesis sought to critically examine the origins, nature and impact of ZANU PF factionalist tendencies and how a particular faction headed by former Vice President Emmerson Dambudzo Mnangagwa was represented in Zimbabwean public discourses. Drawing from comparative politics, history, media studies and Zimbabwean current affairs, this interdisciplinary narrative detailed how the new media played a central role in precipitating factional implosion in the liberation war based political party (ZANU PF). Clearly, ZANU PF internecine conflicts in and outside the state controlled and new media had far-reaching socio-economic and political ramifications as rival ZANU PF factions resorted to dirty strategies and tactics to try and weaken and outwit each other. These political machinations took the form of slandering, use of hate speech, dissemination of fake news, assassinations and poisoning among others. As the battle for factional supremacy raged on, the Zimbabwean economy continued on a downward spiral due to inter alia policy contradictions and uncertainty but at the end, November 2017 saw Mugabe being unexpectedly deposed in a coup after 37 years in power. This study went on to identify a number of factors that were working against Mugabe’s patient and heir apparent – Mnangagwa, as he sought to take over the reins of power. These included inter alia the presence and close proximity of the G40 faction linked to the first family but opposing the former vice president, his tainted political record as a result of his involvement in the Matabeleland massacre of the Ndebele ethnic group in the 1980s, allegedly masterminding and engineering electoral fraud in 2008 and having been Mugabe's right hand man for almost four decades. On the other hand, findings from this study suggest that Mnangagwa’s liberation war credentials and his close association with the military and the war veterans played a pivotal role in assisting him to land the presidency following Mugabe’s forced resignation or what was defined by many as a coup. While the Lacoste faction eventually prevailed over their G40 rivals, the study concluded that ZANU PF factionalism negatively impacted on governmental decisions, policies and systems and the aftermath of the military coup continues to pose serious challenges to Zimbabwe’s political future however defined.

- Language: English

- Description: South Africa enacted the following legislation, the Constitution, the Promotion of Equality and Prevention of Unfair Discrimination Act 4 of 2000 and the Employment Equity Act 55 of 1998 and the Labour Relations Act 66 of 1995. In terms of the Constitution a notion of substantive equality was incorporated in the Bill of Rights. Section 9 of the Constitution specifically provides that no person may be discriminated against and provides a list of grounds which are specifically prohibited. Furthermore, the Constitution affirms the values of equality, dignity and freedom. The Promotion of Equality and Prevention of Unfair Discrimination Act 4 of 2000 aims at eliminating social and economic inequalities which were created by apartheid. The Employment Equity Act 55 of 1998 is similar to the Promotion of Equality and Prevention of Unfair Discrimination Act and takes into consideration the inequalities in employment, occupation and income which exist as a result of apartheid. In maintaining the objective of this treatise, section 6(2) of the EEA must be seen as an extension of and read in light of section 9(2) of the Constitution which provides that equality includes the full and equal enjoyment of all rights and freedoms and permits the use of legislative and other measures, designed to protect or advance persons or categories of persons disadvantaged by unfair discrimination in the past for the purpose of achieving substantive equality. Therefore, section 6(2)(a) of the EEA may be considered the statutory equivalent of section 9(2) of the Constitution. The Constitution of the Republic of South Africa, 1996 has a key and crucial commitment to substantive equality and to correct the imbalances of the past and to create a less divided society in which the constitutional democracy can be advanced. The Constitution identifies human dignity, the achievement of equality and the advancement of human rights and freedoms as some of the basic values upon which South Africa is founded. The Constitution restraints the state and any person from unfairly discriminating on grounds that adversely impacts upon dignity. It further empowers the state to take legislative and other measures to advance persons previously disadvantaged by unfair discrimination. This treatise covers the test for affirmative action as in the Harksen Test, Minister of Finance v Van Heerden and recently strengthened in Solidarity obo Barnard v SA Police Services. It also deals with the Barnard trilogy. Of significance is that the Constitutional Court judgment in Barnard is the first Constitutional Court judgment dealing with affirmative action and its application in terms of the EEA. The judgment strengthens the Constitutional Court finding in Van Heerden in that a restitutionary measure such as affirmative action is not presumed unfair unless it complies with the section 9(2) “internal test”. The Post Barnard Judgment is also discussed in this treatise with reference to the following cases: Mgolozeli v Gauteng Department of Finance and Another, Solidarity and the Department of Correctional Services, South Africa Police Service v the Public Service Association of South Africa: Captain Munsamy and another and Solidarity v the Minister of Safety and Security and others.

- Description: This thesis uses the urban growth and development theory in analysing and applying place-based approaches in the growth and development of the city of East London. Globalisation despite its seeming elimination of distance has in fact made geographical locations more necessary as agglomeration acts as a comparative and competitive advantage for growth and development. It is the contention of this study that places and spaces can develop more rapidly if there exists factors that support innovation and clustering. In this case, HEIs in cities are described as catalysts for growth and development within cities. By their presence in cities and their contribution through knowledge creation, production, dissemination and sharing, they become anchors of development in post-industrial cities that no longer depend on heavy industries but are driven by knowledge, hence, the knowledge economy. There are several city development theories, those that advocate for the use of big projects; others for infrastructure development; and some, for industrialization as a way to revitalize and drive city economic growth and development. This study argues that these development strategies have previously been used in the East London case but with very little success. It seeks therefore to propose that in addition to these, an anchor strategy, whereby institutions such as universities and hospitals, can be used by cities for their growth and development.

- Description: Enterovirus 71 can be a severe pathogen in small children and immunocompromised adults. Virus uncoating is a critical step in the infection of the host cell; however, the mechanisms that control this process remain poorly understood. We applied normal mode analysis and perturbation response scanning to several complexes of the virus capsid and present a coarse-graining approach to analyze the full capsid. We show that our method offers an alternative to expressing the system as a set of rigid blocks and accounts for the interconnection between nodes within each subunit and protein interfaces across the capsid. In our coarse-grained approach, the modes associated with capsid expansion are captured in the first three nondegenerate modes and correspond to the changes observed in structural studies of the virus. We show that the resolution of the analysis may be modified without losing information on the global motions leading to uncoating.

Ngenxa yesi sizathu, eyona njongo iphambili yolu phando kukuzama ukuyila nokuvelisa isixhobo esinokusetyenziswa ekwaziseni nasekuxhobiseni abafundi besiXhosa abakwinqanaba leFET, ngezakhono zokubhala eziphuhlileyo nezikumgangatho wobhalo lwamaziko emfundo enomsila. Kule meko, ingcali yophando kwezobhalo lolwimi uMartin (2009) uhlomla ngelithi ubhalo olujolise ekunikeni iimpendulo, lubonwa njengohlobo lokubhala oluneengcambu ezimiliselwe ekufundisweni nasekungeneleleni ngokugqibeleleyo ngezakhono zokubhala, bhalo olu lunokuthi emva kwethuba elithile, luphelele kwincochoyi yokushicilelwa, lube ngamaxwebhu ahlelwe ngokusesikweni. Iindlela okanye izixhobo zokubhala eziyilwe ngeenjongo zokunikeza iimpendulo, nezithathwe kuphando lukaFeez noJoyce (1998), zizo eziza kusetyenziswa njengenxalenye yoqeqesho nakumaphulo ongenelelo oluza kuxhasa abafundi besiXhosa benqanaba leFET, nanjengoko ezi zixhobo zibonakala zinegalelo elincomekayo kwindlela ekubhalwa ngayo iimpendulo zeetekisi zoncwadi, ngokuthi zigxile kwezi njongo zilandelayo: (i) Ukunika abafundi ulwazi lokuzuza ulwazi olunzulu nolugqibeleleyo ngokuphathelele kwiinjongo zetekisi. (ii) Ukunika inkcazelo ecacileyo ngokubaluleka kwesakhiwo setekisi kwanokubunjwa kwayo. (iii) Ukuxhobisa abafundi ukuze bakwazi ukuchonga ulwimi oluxabisayo, iimpawu zobume bamagama negrama, kuquka nemiba ephambili yamasiko kwiitekisi zoncwadi. Ngenxa yezi njongo, kufikelelwa kuqikelelo oluthi, kuya kuthi ngokusetyenziswa kwesixhobo sikaFeez noJoyce seZakhono zokuBhala, sixhobo eso sayame kwiinqobo zeNgcingane yokuXabisa okufundwayo nedandalaziswa nguMartin noWhite (2006; 2005 no-2003) nayo le ngcingane eluncedo ekufundisweni kokubhala, abafundi abaninzi boncwadi lwesiXhosa kukholeleka ukuba bakukwazi ukuphuhlisa izakhono zokubhala iitekisi ezinika iimpendulo ezihlahlela imiba ephambili yoncwadi abalufundisiweyo. Olu phando lukwahlabela mgama lubonisa nokuba nezinye izixhobo zoyilo lweetekisi zikaGrabe noKaplan (1996), zinakho ukusetyenziswa ngaxesha linye neenqobo zeNgcingane yokuXabisa okufundwayo, kuquka nemiba yeZakhono zokuBhala, ukuze kwandiswe oku kuphuhliswa kwezakhono zokubhala kubafundi besiXhosa, kungaphelelanga kumabanga aphezulu, koko kufikelelwe nakumabanga asezantsi, nanjengoko kuveziwe kwiziphumo, kwizishwankathelo nakwisiphelo solu phando.

Iindlela okanye izixhobo zokubhala eziyilwe ngeenjongo zokunikeza iimpendulo, nezithathwe kuphando lukaFeez noJoyce (1998), zizo eziza kusetyenziswa njengenxalenye yoqeqesho nakumaphulo ongenelelo oluza kuxhasa abafundi besiXhosa benqanaba leFET, nanjengoko ezi zixhobo zibonakala zinegalelo elincomekayo kwindlela ekubhalwa ngayo iimpendulo zeetekisi zoncwadi, ngokuthi zigxile kwezi njongo zilandelayo: (i) Ukunika abafundi ulwazi lokuzuza ulwazi olunzulu nolugqibeleleyo ngokuphathelele kwiinjongo zetekisi. (ii) Ukunika inkcazelo ecacileyo ngokubaluleka kwesakhiwo setekisi kwanokubunjwa kwayo. (iii) Ukuxhobisa abafundi ukuze bakwazi ukuchonga ulwimi oluxabisayo, iimpawu zobume bamagama negrama, kuquka nemiba ephambili yamasiko kwiitekisi zoncwadi. Ngenxa yezi njongo, kufikelelwa kuqikelelo oluthi, kuya kuthi ngokusetyenziswa kwesixhobo sikaFeez noJoyce seZakhono zokuBhala, sixhobo eso sayame kwiinqobo zeNgcingane yokuXabisa okufundwayo nedandalaziswa nguMartin noWhite (2006; 2005 no-2003) nayo le ngcingane eluncedo ekufundisweni kokubhala, abafundi abaninzi boncwadi lwesiXhosa kukholeleka ukuba bakukwazi ukuphuhlisa izakhono zokubhala iitekisi ezinika iimpendulo ezihlahlela imiba ephambili yoncwadi abalufundisiweyo. Olu phando lukwahlabela mgama lubonisa nokuba nezinye izixhobo zoyilo lweetekisi zikaGrabe noKaplan (1996), zinakho ukusetyenziswa ngaxesha linye neenqobo zeNgcingane yokuXabisa okufundwayo, kuquka nemiba yeZakhono zokuBhala, ukuze kwandiswe oku kuphuhliswa kwezakhono zokubhala kubafundi besiXhosa, kungaphelelanga kumabanga aphezulu, koko kufikelelwe nakumabanga asezantsi, nanjengoko kuveziwe kwiziphumo, kwizishwankathelo nakwisiphelo solu phando.

Ulwazi olukhoyo kolu phando lujolise ekuphandeni, uphicotho–nzulu kuphononongwa iincwadi zesiXhosa ezikhethiweyo. Phambi kokuba kujongwe okuqulathiweyo ngababhali bezini kufuneka kujongwe kuqwalaselwe indlela ababhali abasebenzisa ngayo ulwimi. Kuza kujongwa nendlela ababazoba ngayo abalinganiswa kuncwadi ingakumbi ababhali abangamadoda, kuba kubalulekile kujongwe indlela abazotywa ngayo kwakunye nolwimi ukuze kube lula ukuqonda indlela olwakhiwe ngayo uphando. Ngokutsho kukaStralton, (1990:98) abalinganiswa basetyhini bakhiwa ngeendlela ezininzi maxa wambi babizwa ngendlela apho eneengcinga ezineentetho ezisoloko zisetyenziswa ezingalunganga, kwanokungalingani kwezini kuba yingxaki esoloko ikho amaxesha amaninzi. Uqhubeka athi abalinganiswa basetyhini bazotywe njengoomama ababopheleleke emakhaya, kodwa benoxanduva lokujonga amakhaya, abantwana, abayeni kwanabantu bomzi. Indawo yabasetyhini ibonwa njengeyokuba isekhitshini apho soloko besebenza khona. Uphinda oleke ngelithi ababhali abangamadoda batyibela abalinganiswa basetyhini njengabantu abangathembekanga ekwenzeni okulungileyo kwanokutyhefa okanye ukungcolisa uluntu entlalweni. ULeslie (1987:05) ucacisa banzi ngabantu basetyhini athi bangabalinganiswa abazotywa kubhalo-ncwadi njengabantu abamele “oomama abaswiti” abavuma yonke into engavumelekanga okanye engathandekiyo kwaye ngabantu abazinikelayo bancame ubom babo. Esi siqu sika“mama” uLeslie (1987:15) uthetha ngaso ehlanganisa “umama waseAfrika” onobuhle ngaphakathi nangaphandle ukwakhiwa kwakunye nokuhlaziyeka kwakhe. Isiqu esihle, uyaphinda-phinda ukuthi, abasetyhini banomonde kwakunye nothando olunovakalelo, indlela ebonakalisa ubunjani babo. Abalinganiswa abaninzi basetyhini bamiswa ziingcinga neentetho ezisoloko zisetyenziswa zezini ukwenzela imigudu nemizamo yabo yokwenyuka itsalelwe ezantsi kubekho imibuzo engenampendulo.
