- Description: Olu phando luza kuthi lugxile kuphononongo lwentsingiselo efihlakeleyo ekusetyenzisweni kolwimi kwiincwadi ezikhethiweyo zesiXhosa. Isizathu sokusebenzisa ezi ncwadi kukubona ukuba ababhali bazo babe nendlela ethile ethi izalane ekubhaleni iincwadi zabo. Ikakhulu aba babhali baza kutyhilwa kungekudala baphume izandla ekusebenziseni ulwimi oluntsonkothileyo kwaye ekungelula kulowo uzifundayo ukukhawuleza ayazi intsingiselo. Loo nto iyodwa iye yakhokelela ekubeni umphandi abe nomdla ekucubunguleni le ntsingiselo kwezi ncwadi zabo. Ezona zinto zingundoqo uphando oluza kuthi lugxininise kuyo, lulwimi kuba lulo olungundoqo wolu phando nangona uphando lona luza kuqwalasela intsingiselo efihlakeleyo. Le ntsingiselo iza kuqwalaselwa kusetyenziswa ulwimi. Ulwimi sesona sixhobo siphuhlisa ngalo iingcamango ezingundoqo zentsingiselo efihlakeleyo. Ukuba asinakulusebenzisa ulwimi, oyena nobangela wokubhala awusoze uphunyezwe luphando. Yile nto uphando kunyanzelekile ukuba lungene nzulu kulwimi, ingakumbi kwisimantiki yona ijongene nentsingiselo. Uphando luza kubetha nje koomofu kumasuntswana elingwistiki angala, ifonetiki, ifonoloji, imofoloji, isimantiki, isintaksi nepragmatiki njengoko kufuneke lujongisise ulwimi ngokubanzi. Luphinde lujonge intsingiselo engundoqo nentsingiselo efihlakeleyo yamagama kwisivakalisi kodwa lona uphando lube lujolise ekutyhileni intsingiselo efihlakeleyo kwiincwadi ezikhethiweyo. Owona ndoqo kukujonga iintsingiselo ezimbini ezahlukeneyo kulwimi. Kukho intsingiselo yolwimi ubani anakho ukuyijonga njengoko eyiva okanye eyibona kuphinde kubekho intsingiselo ethi ifihlakale leyo ke ubani angasayi kukhawuleza ayibone de abe kanti uzikisa ukucinga. Uphando luza kukekelela kwiintsingiselo ezimbolo-mbini kuba lufumanisa ukuba igama elinye liyakwazi ukutshintsha intsingiselo yonke yesivakalisi. Koko kubalulekile ukuba uphando luchaphazele oomabizwafane noomabizwahluke kuba bangayijika intsingiselo yesivakalisi. Kwakhona uphando luza kujonga indlela yentsingiselo apho isivakalisi siye sivakale ngendlela ethile ezindlebeni zalowo ufunda loo tekisi, abe umbhali engajolisanga kuloo mxholo umfundi yena awuve ngendlela yakhe. Kolu phando kuyanyanzeleka kucutyungulwe indlela ababhali abalusebenzisa ngayo ulwimi olufihlakeleyo kwiincwadi ezikhethiweyo. Ezi ntsingiselo zifihlakeleyo zingavezwa ngeendlela ezininzi ezizezi; imifanekiso ntelekelelo/imifanekiso ngqondweni, ngemiqondiso, izigqebelo, amaphupha, indalo, uphawu nezafobe ezithile. Zonke ezi mpawu zikhankanyiweyo ngentla zizo eziza kuthi zijongwe kwezi ncwadi zaba babhali. Isimiyotiki yona kuza kuthi kudlulwe kuyo kuba yona nesimantiki ziyathungelana asikwazi ukuthetha ngentsingiselo efihlakeleyo yolwimi sijike siyishiye isimiyotiki. La macandelo kuza kucaciswa ukubonisa imvelaphi yolwimi kodwa kungagxilwanga kuwo.

- Description: Non-communicable diseases (NCDs) such as cancer, diabetes, and chronic respiratory and cardiovascular diseases continue to be threatening and deadly to human kind. Resistance to and side effects of known drugs for treatment further increase the threat, while at the same time leaving scientists to search for alternative sources from nature, especially from plants. Pentacyclic triterpenoids (PT) from medicinal plants have been identified as one class of secondary metabolites that could play a critical role in the treatment and management of several NCDs. One of such PT is ursolic acid (UA, 3 β-hydroxy-urs-12-en-28-oic acid), which possesses important biological effects, including anti-inflammatory, anticancer, antidiabetic, antioxidant and antibacterial effects, but its bioavailability and solubility limits its clinical application. Mimusops caffra, Ilex paraguarieni, and Glechoma hederacea, have been reported as major sources of UA. The chemistry of UA has been studied extensively based on the literature, with modifications mostly having been made at positions C-3 (hydroxyl), C12-C13 (double bonds) and C-28 (carboxylic acid), leading to several UA derivatives (esters, amides, oxadiazole quinolone, etc.) with enhanced potency, bioavailability and water solubility. This article comprehensively reviews the information that has become available over the last decade with respect to the sources, chemistry, biological potency and clinical trials of UA and its derivatives as potential therapeutic agents, with a focus on addressing NCD.

- Description: Non-communicable diseases (NCDs) such as cancer, diabetes, and chronic respiratory and cardiovascular diseases continue to be threatening and deadly to human kind. Resistance to and side effects of known drugs for treatment further increase the threat, while at the same time leaving scientists to search for alternative sources from nature, especially from plants. Pentacyclic triterpenoids (PT) from medicinal plants have been identified as one class of secondary metabolites that could play a critical role in the treatment and management of several NCDs. One of such PT is ursolic acid (UA, 3 β-hydroxy-urs-12-en-28-oic acid), which possesses important biological effects, including anti-inflammatory, anticancer, antidiabetic, antioxidant and antibacterial effects, but its bioavailability and solubility limits its clinical application. Mimusops caffra, Ilex paraguarieni, and Glechoma hederacea, have been reported as major sources of UA. The chemistry of UA has been studied extensively based on the literature, with modifications mostly having been made at positions C-3 (hydroxyl), C12-C13 (double bonds) and C-28 (carboxylic acid), leading to several UA derivatives (esters, amides, oxadiazole quinolone, etc.) with enhanced potency, bioavailability and water solubility. This article comprehensively reviews the information that has become available over the last decade with respect to the sources, chemistry, biological potency and clinical trials of UA and its derivatives as potential therapeutic agents, with a focus on addressing NCD.

- Description: Urban green spaces provide an array of ecosystem services. Spiritual services provided by urban green spaces are widely used, but are often overlooked and rarely quantified. These services are accessed at sites of specific religious or sacred significance or more general urban green spaces used for religious practices that require natural or semi-natural, outdoor settings. We sampled twelve public green spaces in Bulawayo, Zimbabwe, to determine their use as sites for religious gatherings, interviewed visitors to green spaces and religious congregants about such and used the travel cost method to assign a value to the green spaces for spiritual benefits. Religious gatherings were observed in all twelve sampled green spaces, and 7% of a random sample of visitors to the urban green spaces said that they participated in such. Amongst the worshippers, 71% said worshipping outdoors was part of their religious practices and 29% said they did so because they had no building in which to worship. Most (79%) worshipped in public green spaces 1–4 times per week. Many felt that it would be easier if the city council designated specific and quiet areas in public green spaces for their religious observances, which they could then help maintain. The mean value of spiritual services was determined to be US$93 ± 79 /ha/yr, and tended to be highest in the high density, poorer suburbs. These results reveal the significance of urban green spaces for spiritual purposes and indicate the need for greater recognition amongst researchers and city planners and authorities to secure and maintain such benefit flows.

- Description: Blended learning is currently the recommended mode of teaching at Nelson Mandela University and typically refers to a mix of traditional methods of teaching and learning integrated with technology, in particular, online delivery methods. In this blended learning study, a web-based learning programme, WileyPLUSLS, in combination with the assessment functions of the learning management system, Moodle, introduced the technology component into the teaching and learning of Anatomy and Physiology. User experience (UX) studies investigate the experiences of a user when using a product or system. Because very little is currently known about the UX when WileyPLUSLS and Moodle are integrated into the teaching and learning of Anatomy and Physiology, this study aims to determine the participants’ UX to compile a set of UX requirements. The purpose of these UX requirements is to inform designers if the programmes WileyPLUS and Moodle function as they should and to modify them, if needed, to improve their usability. These UX requirements also aim to support and guide the integration of blended learning technologies into the curriculum of Anatomy and Physiology and other disciplines alike. The research design selected for this study was in the form of a case study conducted on the 2016 first-year BHSc: MLS (Bachelor of Health Sciences in Medical Laboratory Science) class at Nelson Mandela University. Pre-study investigations on infrastructure, connectivity and e-readiness were conducted to lay the groundwork for the case study and to inform its rationale. Data was collected from literature studies, online UX questionnaires, semi-structured interviews and researcher observations. A mixed methods approach to data analysis was adopted. Quantitative data from the UX questionnaire were analysed by means of descriptive statistics, whereas qualitative data from semi-structured interviews, open-ended questions from UX questionnaire and researcher observations were analysed via content analysis. Subsequently the analysis and triangulation of the data culminated into UX requirements, which were categorised into the following classifications, namely infrastructure, human resources, educational content and online learning systems. This case study illuminated many major issues regarding connectivity, e-readiness, unequal access to online learning, the importance of security features for online summative assessments, the usefulness of commercial web-based learning programmes and the confounding effect of the #FeesMustFall (FMF) protest movement. Finally, the influence of artificial intelligence (AI) on online learning and the workplace was addressed. This research was successful in compiling the UX requirements to inform designers regarding the usability of their systems and to guide the integration of online programmes into the curriculum, especially in the South African context of limited and slow connectivity.

- Description: The leerfish (Lichia amia), is a large, primarily coastal recreational fish species with a distribution extending from Portugal down the west coast of African to southern Mozambique. Owing to its large size (30 kg), strong fighting abilities and habit of taking surface artificial lures, this species has taken on an iconic stature among shore-based recreational anglers. Its reputation has made it an important angling tourism species that makes an important contribution to the economy of developing countries. For example, the species brought US$243 per harvested kilogramme into the local southern Angola economy. Despite its high value, little is known about its movement patterns in the northern Benguela coastal region, a region which includes southern Angola and northern Namibia. While much is known about the migratory patterns of the South African stock of L. amia, recent molecular studies have shown that the northern Benguela stock of L. amia has been isolated from the South African population for at least two million years, a consequence of the development of the cold Lüderitz upwelling cell in southern Namibia. Although the global population of L. amia is considered a single species, prominent biogeographic barriers within its distribution and subtle morphological differences between specimens captured within its tropical versus warm-temperate distribution suggest otherwise. A multi-method approach incorporating passive acoustic telemetry (PAT), recreational catch-per-unit-effort (CPUE) and conventional tagging (CT) in southern Angola, as well as recreational fisher-ecological knowledge (FEK) from Namibia, was used to investigate the large-scale movement patterns of L. amia within the northern Benguela coastal region. While each method had its own associated limitations, the combination provided a holistic picture of the population's seasonal migratory patterns. Furthermore, PAT successfully identified partial migration with 25% vs 75% of monitored fish exhibiting resident (movements < 100 km) or migratory (movements > 100 km) behaviour, respectively. Further behavioural diversity was observed with ‘resident’, ‘roaming’ and ‘embayment’ contingents identified based on varying levels of affinity to certain habitats. The presence of both resident and migratory individuals within the northernmost study during June and July, combined with available biological information, suggested that area-specific spawning may take place. While PAT, CPUE and CT largely aligned in determining area specific high-area use, results from network analyses and mixed effects models conducted on the PAT data supported the spawning hypothesis, with anomalous behaviour around specific receivers during the spawning season. All fish, regardless of behavioural contingent, displayed similar movement behaviour during the spawning season and this was driven by factors generally associated with reproduction, such as lunar illumination. Interestingly, these drivers were different from those that determined the area specific use of individuals outside of the spawning season. The environmental drivers of longshore migration into the northern study site were identified as a decline in water temperature and shorter day lengths. The results of this study highlight the importance of using a multi-method approach in determining migratory movement behaviour, area specific area use, and stock structure of key fisheries species. The identification of different behavioural contingents highlights the importance of acknowledging individual variation in movement and habitat-use patterns. This is particularly relevant as future climate change and spatiotemporal variation in fishing effort may artificially skew natural selection processes to favour certain behavioural groups. This study also highlighted the importance of scientists forming relationships with resource-users, such as recreational angling lodges in areas where limited research has been conducted. This is particularly relevant within the West African context where little is known about many of the fish species that are being increasingly targeted by tourism angling ventures.

- Description: Widespread research exists about the challenges of getting boys to read and the gap in reading performance between boys and girls. Using a case study design within a qualitative approach, this study investigated whether engagement in a reading club could help boys in the Kingdom of Saudi Arabia to position themselves as readers. The literature review examined factors that hindered or advanced reading and the reading development of boys, particular in the Arab-Muslim context. Two theoretical frameworks underpin this study: Social Learning Theory which allowed for reading engagement of a social nature and Third Space Theory which enabled this engagement bringing together the in and out of school literacy practices. Grade 4 students at a school in Saudi Arabia were invited to partake in a 45 minute after-school reading club for 12 consecutive weeks. Participatory Visual Methodologies and a Reflective journal were used to generate data. Participants were asked to make drawings to express how they felt about reading in different languages and drawings to express how they felt about reading English books in a reading club. Drawings accompanied by verbal feedback along with the reflective journal notes were analysed using thematic analysis. Results from this study showed that a reading club serving as a socially supportive space does help boys in the Kingdom of Saudi Arabia to position themselves as readers.

- Description: Wetlands are critical ecosystems that can provide services of great social, economic and environmental value to the society. Yet, in South Africa, hillslope seep wetlands are among the most threatened ecosystems due to human-induced activities and are disappearing rapidly. Further, despite the potential vulnerability of hillslope seep wetland to disturbances, and their criticality in relation to all year round provision of forage for livestock grazing, they are among the most poorly studied wetland systems. Using a social-ecological system framing, and drawing on a range of ecological and social sciences methods, this study shed light on ways in which an integrative approach can contribute to sustainable utilisation of hillslope seep wetlands in the Tsitsa River catchment in the Eastern Cape province of South Africa. The study specific objectives were to i) evaluate the performance of Floristic Quality Assessment Index (FQAI), WET-Health and Floristic Assessment Quotient for Wetlands Index (FQAWet) indices for assessing hillslope seep wetlands ecological health ii) develop a trait-based approach for assessing the potential resilience and vulnerability of hillslope seep wetland plant species to disturbances, iii) assess the role of hillslope seep wetlands in the local communities in relation to livestock, and explore understanding of local people about the value of hillslope seep wetlands, iv) demonstrate collaborative insights emerging from an integrative social-ecological system research process to inform sustainable management of hillslope seep wetlands. A total of 11 hillslope seep wetlands were visually classified based on the level of erosion. Plant species composition within the wetlands was determined along a 100 m line transects across the hillslope wetland sites. 5 quadrats of 0.2m2 were also placed along transect for vegetation collection and cover. The plant species collected were used to calculate (FQAI) and FQAWet scores to evaluate the condition of hillslope seep wetlands. The degree of human disturbances was assessed using the Anthropogenic Activity Index (AAI), an index for qualitatively assessing the degree of human disturbance based on visual inspection of a wetland site. Factors represented in the AAI, include: (i) surrounding land use intensity; (ii) soil disturbance; (iii) hydrological alteration; (iv) habitat alteration within wetland; (v) vegetation community quality. The vegetation samples were collected in summer 2016 and winter 2017. All assessed indices were regressed against AAI to evaluate their performances. All assessed indices FQAI, FQAWet and WET-Health showed that hillslope seep wetland were impacted by human activities. FQAIall and WET-Health showed the strongest response to AAI in winter, while FQAIdom and FAQWet showed a weak response to AAI in all seasons. Overall, the findings of this study suggest that FQAIall and WET-Health are potentially better tools for assessing the biological conditions of hillslope seep wetland in South Africa. A novel trait-based approach was developed using seven plant traits and 27 trait attributes. Based on the developed approach, plant species were grouped into three potentially vulnerable groups in relation to grazing pressure. It was then predicted that species belonging to the highly vulnerable group would be less dominant at the highly disturbed sites, as well as in the winter season when grazing pressure is at its highest. The result corresponds largely with the seasonal predictions; however this was not the case for sites. The approach developed in this study worked and it was useful for predicting the potential responses of plant species in hillslope seep wetlands to grazing pressure. The success of the approach seasonally could be attributed to the careful selection of the traits, reflecting the mechanistic relationship between the grazing mode of stress on vegetation and trait-mediated biotic response. However, this still need to be refined using accurate vegetation cover methods that might have had impact on the lack of correspondence within sites. The results of the present study revealed that communities largely perceive hillslope seep wetlands as important ecosystems for their livelihoods. They recognise that the importance stems from services provided by the wetlands, particularly for livestock grazing during the dry season. Although hillslope seep wetlands are viewed as important ecosystems for livelihoods, the communities also perceive these wetlands as highly eroded ecosystems. Community members indicate willingness to strengthen local natural resource governance systems, which could lead to better management of hillslope seep wetlands. A range of protective strategies for hillslope seep were suggested by community members, including fencing, active herding and rotational grazing. The study suggests that active involvement of local communities is critical to the successful management of natural resources. The study highlights the need to consider the role of local people as influential components within social-ecological systems in order to promote effective management and conservation interventions of hillslope seep wetlands. Overall, the study highlights the criticality of an integrative social-ecological system approach for holistic management of hillslope seep wetlands within the studied catchment.

The approach developed in this study worked and it was useful for predicting the potential responses of plant species in hillslope seep wetlands to grazing pressure. The success of the approach seasonally could be attributed to the careful selection of the traits, reflecting the mechanistic relationship between the grazing mode of stress on vegetation and trait-mediated biotic response. However, this still need to be refined using accurate vegetation cover methods that might have had impact on the lack of correspondence within sites. The results of the present study revealed that communities largely perceive hillslope seep wetlands as important ecosystems for their livelihoods. They recognise that the importance stems from services provided by the wetlands, particularly for livestock grazing during the dry season. Although hillslope seep wetlands are viewed as important ecosystems for livelihoods, the communities also perceive these wetlands as highly eroded ecosystems. Community members indicate willingness to strengthen local natural resource governance systems, which could lead to better management of hillslope seep wetlands. A range of protective strategies for hillslope seep were suggested by community members, including fencing, active herding and rotational grazing. The study suggests that active involvement of local communities is critical to the successful management of natural resources. The study highlights the need to consider the role of local people as influential components within social-ecological systems in order to promote effective management and conservation interventions of hillslope seep wetlands. Overall, the study highlights the criticality of an integrative social-ecological system approach for holistic management of hillslope seep wetlands within the studied catchment.

- Description: We investigated the presence of medium-sized and large mammals utilizing by-catch data from a camera trapping survey in the Mangwe District in South West Zimbabwe, an unprotected commercial livestock farming area which is impacted by human encroachment, poaching and trophy hunting. The camera trapping survey was carried out from 23 October to 5 December 2009, covered an area of 200 km2 and was initially intended to estimate the population density of leopards (Panthera pardus). The study area was split into two contiguous subsections, with each section sampled for a total of 20 days using 20 cameras. Camera trap photographs were identified to species level, then compared to a list of species thought to occur in the area according to available literature, as well as sightings from professional hunters and local landowners.

- Description: Stable isotope (SI) ratios of carbon (δ13C) and nitrogen (δ15N) are now widely used as biomarkers in ecological studies to provide information about food web structuring. However, understanding trophic relationships using SI analysis requires not only knowledge of SI values of predator and prey, but also accurate discrimination factors (DFs), which can differ among species and by physiological state. This thesis examined three questions using captive birds from the South African Foundation for the Conservation of Coastal Birds (SANCCOB). First, the effects of ontogeny on δ13C and δ15N ratios of African penguins (Spheniscus demersus) were assessed. Blood samples were collected from penguins in four age classes (P3 chicks, blues, juveniles and adults) concurrently with their diet (sardine (Sardinops sagax) and formula). Second, to assess the influence of breeding physiology on SI ratios, the blood of ten breeding pairs of penguins was sampled over a five-month period from June to October 2016. Following laying, each pair was categorised into one of three (four for whole blood) egg production phases (initial yolk deposition, rapid yolk deposition and post-laying) and their influences on SI ratios were tested. Third, species differences in DFs were evaluated for African penguins, kelp and Hartlaub’s gulls (Larus dominicanus and L. hartlaubii), greater crested terns (Thalasseus bergii) and Cape cormorants (Phalacrocorax capensis). Flying birds were mostly fed sardine with a small but unknown amount of sardinella (Sardinella aurita), DFs were therefore estimated for a 50:50 sardine:sardinella diet, a 75:25 sardine:sardinella diet and a 100% sardine diet for each flying bird species. The DFs were assessed for the whole blood (WB), red blood cells (RBC), plasma (PL) and delipidated plasma of the penguins, and only WB for the flying birds as well as flesh, whole fish, delipidated flesh and delipidated whole fish for fish species, and for formula. Results indicated that age influenced both the δ13C and δ15N of WB, only the δ15N of RBC and the δ13C of delipidated PL. The assessment of breeding physiology yielded a significant interaction between the effects of egg production phase and sex on the δ13C of WB; females had significantly lower δ13C in the rapid yolk deposition phase than the other two phases and all males. The δ13C of PL was affected only by sex, with females having a significantly lower δ13C value than males. Neither physiological state nor sex influenced the other blood components. Differences were found among the three DFs in the non-penguin species, but not for all consumer – prey tissue combinations. There were also significant differences among species with a DF calculated from a diet with the most probable prey proportions eaten. Depending on the combination of consumer and prey tissue used to calculate the DF, a different conclusion regarding trophic information can be reached. A literature review updated with the present data showed that no general pattern or grouping of similar species with regards to DF values could be drawn, highlighting the importance of determining species- and tissue-specific DFs. Thus age, egg production, tissue and species all influenced the SI values of bird blood and therefore their DFs. Not all physiological conditions affect all blood components in the same way, making different components more or less sensitive to physiological influences. Though their influence is at a small enough scale that it is unlikely to hamper correct conclusion in ecological studies, it is crucial that these factors are considered when using SI analysis (SIA). When uncertainties exist for some coefficients in wild studies, SIA should therefore be combined to other dietary techniques to determine the food web structure as best as possible.

- Description: Four different techniques to make taxonomic decisions concerning different species in Scarabaeinae are being investigated. Firstly, I made measurements of the body dimensions which are plotted on a two dimensional graph. This method is successfully used to erect one new species, Copris crassus Deschodt and Davis, 2015, and to establish the synonymy of Copris bihamatus Balthasar, 1965 with Copris fidius (Olivier, 1789). Thereafter the classical or traditional comparative method is used to propose seven new species Scarabaeolus soutpansbergensis (Deschodt and Davis 2015), Scarabaeolus megaparvulus (Davis and Deschodt 2015), Scarabaeolus niemandi (Deschodt and Davis 2015), Scarabaeolus carniphilus (Davis and Deschodt 2015), Scarabaeolus ermienae (Deschodt and Davis 2015), Scarabaeolus planipennis (Davis and Deschodt 2015) and Scarabaeolus afronitidus (Davis and Deschodt 2015) and formally synonymise Scarabaeolus vansoni (Ferreira, 1958) with Scarabaeolus lucidulus (Boheman, 1860) and Scarabaeolus xavieri (Ferreira, 1968) with Scarabaeolus andreaei (zur Strassen, 1963). Morphometric measurements of external structures of a group of flightless relict beetles in the tribe Canthonini are used to compile a nexus file which is analysed with computer software. The interpretation of these results is used here to support the erection of a new genus Drogo Deschodt, Davis & Scholtz 2016, Lastly I analysed the DNA sequences of specimens from different species belonging to a species complex in the genus Epirinus Reiche, 1841 occurring over a wide geographic range. These sequences are used together with external morphological characters to propose the synonymy of Epirinus hluhluwensis Medina & Scholtz 2005 and Epirinus ngomae Medina & Scholtz 2005 with Epirinus davisi Scholtz & Howden 1987.

- Description: The main purpose of this study is to identify water stressed areas as a response to climate variability (Drought), Aridity, and water exploitation in the Raymond Mhlaba Local Municipality (RMLM) using Geographical Information Systems (GIS) and Remote Sensing (RS). This study focused on evaluating whether it is best to address the issue of drought and water stress as a municipal problem instead of a community-based problem. To achieve this, the study was attempting to establish four things: the climate condition of the municipality, whether the municipality is a drought prone area, how the surface water is being exploited in the municipality, and identify areas that should be considered water stressed areas. There are several indices used to compute water stress and the study opted for indices that can monitor climate variability, and surface water resources. Therefore, the de Martone Aridity Index (MA) was used to compute the aridity of the municipality the Standardized Precipitation Evapotranspiration Index (SPEI) to compute drought, and the Water Exploitation Index (WEI) to measure population water exploitation. Data used was from 25 weather stations provided by the Meteoblue website and water data from the department of water and sanitation. Thereafter, the Analytical Hierarchy Process (AHP) was used to determine the weights of each variables’ contribution to water stress. For validation, the Shapiro, Jarqua Bera and Kolmogorov-Smirnov tests were used and results showed that the data was normally distributed and a two-sample t-test confirmed that there was no significant difference between the measured and simulated data. According to the de Martonne there are three main climatic regions in the Raymond Mhlaba Municipality namely: the Mediterranean, semi-humid and humid region. The Mediterranean region is equally prone to drought as the humid region while the semi-humid region was a wet prone. This was contradictory to literature that expected drier regions to experience more frequent drought. However, this may have been influenced by the number of weather points that cover the humid region that is far lower than the ones covering the Mediterranean region. In addition, the municipality is 50% drought prone and would experience extreme events about 30% of the time. The study discovered that towns such as Fort Beaufort, Alice, Adelaide, and Middle drift are water stressed areas. While most of the other regions are low water users. These challenges with water stress could be reduced with the implementation of water saving mechanisms such as water tanks and the avoidance of addressing water stress as municipal challenges as opposed to a town specific challenge.

- Description: The purpose of this research was to examine the utilisation of Teaching and Learning Centres (TLC) in state universities in Zimbabwe and the role they are playing in the improvement of teaching and learning in the institutions of higher learning. The social constructivist paradigm was found most appropriate for this study and was the lens by which reality was examined. The study used the qualitative approach and case study design to examine the issue under study. The purposive sampling technique was used to select participants who were rich informants for the study and these included Pro Vice Chancellors, Directors of Teaching and Learning Centres, Deans, lecturers and students. Data were collected through face to face interviews and focus group discussions that were triangulated by analysis of institutional records. The study was also guided by the theoretical lenses of the Social Practice Theory and the Concerns Based Adoption Model that provided the framework for the investigation. The study employed the Tech‘s qualitative model of data analysis that led to the findings being grouped into five major themes. The study established that Teaching and Learning Centres were not being fully utilised, thus were not helping to improve teaching and learning in a meaningful way in state universities in Zimbabwe. Possible reasons for this were the fact that the unit was not fully understood and different players at different levels in groups and as individuals had varied interpretations of what the TLCs were and what their role in the university was supposed to be. This lack of understanding and the absence of a shared understanding of what TLCs are and what they stand for, coupled with other factors such as the freeze on recruitment on staff in state universities and the assumed superiority of research over teaching for tenure and viii promotion, led to the poor positioning and poor staffing of TLCs leading to their poor utilisation in state universities. Each of the staff levels also had concerns about the utilisation of the TLC that made them reluctant to utilise it. The absence of top management support for the TLC, and the perceived superiority of research over teaching again led to poor utilisation of the unit. The study recommends the hosting of symposia between and among state universities for the dissemination of knowledge and information on what the TLC is and what its role should be. Internal consultations by individual state universities on the functions, staffing and positioning of the TLC and exposure for the TLC staff to established units to raise their knowledge and information levels and confidence is encouraged. Removal of the freeze on recruitment of staff so that TLCs can be better positioned and staffed and review of ZIMCHE guidelines to align teaching, research and university service for tenure and promotion would also help. Acquisition of cutting edge technology for teaching and learning and top management to listen to individual and group concerns and act on those that impede on TLC utilisation is a must.

- Description: Ever since the transition post-1994, the South African economy have been faced with increasing unemployment rates, and an increasing labour force but not sufficient job opportunities to absorb these new entrants. Labour market conditions in South Africa can be considered tight after taking into account the high rates of unemployment and labour force participation. A unique empirical relationship surfaced within the macroeconomics context which had a significant impact on economic thinking. Beveridge (1944) postulated that there is a negative relationship between job vacancies and unemployment, and it is depicted by the Beveridge curve. This study therefore analysed the relationship between vacancies and unemployment in South Africa from 2008 to 2016. An autoregressive distributive lag (ARDL) model was employed to carry out the objectives of this study and the results suggested that there is a positive relationship between these two variables; which imply that the Beveridge curve theory does not apply to labour market of South Africa. This in turn suggests that labour demand and labour supply exists concurrently in this particular market. Thus, it is commendable for policy makers to have an in-depth introspection at the skills-supply, and the policies examining unemployment in South Africa to ensure that the unemployed fill the unfilled vacancies.

- Description: Understanding the values and workplace expectations of young South African graduates, referred to in this study as Millennials, is vital for the future success of organisations. Organisations gain a competitive advantage by attracting, engaging and retaining top talent. Millennials are not always positively received in the workplace, due to the prevailing stereotypes held about this group. However, the Millennial generation has an important role to play in the workplace, both in contributing towards organisational success, and as future leaders. A greater understanding of this generation, more particularly in terms of their values and workplace expectations, is thus necessary for ensuring effective talent acquisition and management strategies. The aim of the study was to identify the values of Millennials, both within their personal and working lives. This is important; as individuals take their values into the workplace. Secondly, the expectations that Millennials have of their employers and workplaces in general was explored. With this understanding in mind, the purpose of the study was to advise organisations on how to better prepare for and accommodate Millennials’ values and workplace expectations, in order to enhance their role in contributing towards organisational success, as well as contributing towards their levels of engagement and job satisfaction. The study adopted a qualitative and phenomenological research design. The sample comprised eight young South African graduates working within the private sector, and residing in Port Elizabeth, within the Eastern Cape province of South Africa, who possessed an undergraduate tertiary qualification, and held at least one year’s work experience. It was further required that the participants fall within the Millennial generational cohort, aged between 22 and 30 years. The sampling technique used was non-probability purposive convenience sampling. One-on-one semi-structured interviews formed the data-collection instrument; and thematic analysis was used for the data processing and analysis. Congruence was identified between the values and the workplace expectations of young South African graduates in the private sector through the semi-structured interviews and the literature review; and between the identified values and the workplace expectations of the eight participants. This study contributes towards the field of knowledge used in describing the nature of the values and the workplace expectations of Millennials; and provides recommendations in terms of workplace implications.

- Description: Understanding the values and workplace expectations of young South African graduates, referred to in this study as Millennials, is vital for the future success of organisations. Organisations gain a competitive advantage by attracting, engaging and retaining top talent. Millennials are not always positively received in the workplace, due to the prevailing stereotypes held about this group. However, the Millennial generation has an important role to play in the workplace, both in contributing towards organisational success, and as future leaders.

- Description: In Kenya, just like in most African countries, ethnicity-related conflicts are a common phenomenon. Often times, the media, especially vernacular radio has been accused of incitement to violence as was in the case of 1994 Rwanda genocide and the 2007 post-election violence in Kenya. As a result, numerous studies have focused on the role that the media, especially vernacular radio plays in perpetuating ethnic conflict, while very little has been done to establish its role in peace building. Therefore, this study was informed by the assumption that the media is a double edged sword; while it can fuel tension and lead to conflict, it can also contribute to peace between conflicting parties. It therefore sought to establish the role that vernacular radio play in peace building in Kenya. The literature reviewed showed that vernacular radio has the potential to promote peace in society. The study was therefore guided by the social responsibility theory which underpins the necessity for the media/ journalist to keep society’s interest as a top priority. This means that the society expects journalists to be accountable, liable and responsible in carrying out their duties. This study utilized both qualitative and quantitative research methods. Using a case study of popular vernacular radio stations in three conflict prone regions in Kenya, the researcher employed content analysis, questionnaires and interviews as tools for data collection. The results indicate that the stations have put in place specific policies aimed at ensuring impartiality in reporting and that journalists adhere to them in their work. The stations also work in partnership with other peace practitioners by developing programs that are aimed at promoting peace within and between communities. Furthermore, the findings indicate that the stations’ journalists largely understand and comply with the sections of the Code of Conduct for the Practice of Journalism in Kenya which addresses the need for responsible conflict reporting. Based on these findings, the study therefore concludes that vernacular radio stations working in conflict prone regions in Kenya play a positive role in peace building. However, the study recommends more specialized trainings for journalists in order for these stations to be more effective in this role of peace building.
