MCom (Human Resource Management) / Department of Human Resources Management and Labour Relations / The objective of this study was to investigate the relationship between ethical leader behaviour and the five factors of personality in Vhembe District, South Africa. This research used a quantitative method. A self-administered questionnaire was used to collect data from a stratified random sample of n=202 participants. All categories from selected government departments of the Vhembe District were included in the strata meaning that junior and senior employees both participated. The Statistical Package for the Social Sciences (SPSS) version 25 was used for descriptive and inferential statistics (Correlation and ANOVA) to determine relationships between ethical leadership and personality factors of agreeableness, consciousness, neuroticism, extroversion and openness to experience. The Personality Factor Scale was used to collect data on the five factors of personality, and the ethical Leaders Scale was used to collect data on the dependent variable of ethical leader behaviour. The findings of this study confirmed that out of the five factors of personality, consciousness had the most a positive significant relationship with ethical leader behaviour. Therefore, this study concludes that selected government departments of the Vhembe District should exhibit ethical leadership to their employees. The study also discovers that fairness, role clarifications and power sharing were the aspect of ethical leadership which is required in every leader to become ethical. / NRF

MESHWR / Department of Hydrology and Water Resources / Communities in South Africa have been noted to consume earthy materials such a soil among others. Geophagy is largely practised in the rural areas as opposed to urban places, and in these places the level of sanitation is low and people usual practice open defecation. The practice of Geophagia has been associated with cultural, medicinal, psychological, religious and nutritional deficiency among others. The aim of the study was to investigate the effects of open defecation on geophagic soils and water resources in Siloam village. The study also aimed to understand the reasons why people practice geophagia in Siloam village and the health effect associated with consumption of geophagic soils. To carry out the aim of the study, a questionnaire survey was conducted among women who practice geophagia between the ages of 18 and above in Siloam village. Two hundred and eighty-three (283) women were selected using snowball sampling method to take part in the study. From the (283) women, (200) women represent the geophagic group and (83) women represent the control group. The existing standard questionnaire adopted to generate data on human geophagia included aspects on demography, socio-economic, cultural, ecological, physicochemical aspects, indigenous knowledge and health effects of geophagic consumers. Participants were asked basic questions on why they practice geophagy, their geophagic material preferences, where they collect the geophagic material and other related questions. A total of twelve soil samples were collected from Siloam village, from the twelve soil samples collected eight were collected from sites known for geophagic practice and another four soil samples were collected from sites where geophagia is not practiced and the samples were used as control soil samples. All the twelve soil samples were analysed for the presence of geohelminths ova using Ammonium Bicarbonate Protocol (AMBIC protocol). The AMBIC protocol consists of four analytical procedures, namely, sample preparation, sample washing with AMBIC solution, geohelminths ova recovery through a modified zinc flotation method and microscopic analysis. vi Furthermore, a total of twelve water samples were collected from Nzhelele River and ponds water in Siloam village. From the twelve water samples, eight samples were collected close to where geophagic materials were collected and where open defecation is reported to be taking place and the remaining four water samples were collected randomly from Nzhelele river and water ponds in Siloam village and was recorded as a control group. A total of 12 water samples were analysed for total coliform and faecal coliform Escherichia Coli (E.coli) indicator using the membrane filter technique. The results from the administration of the questionnaire revealed there was prevalence in the practice of geophagia in the area. The study found that most of the villagers in Siloam consumed soil nearly on daily basis. According to the results, only women were involved in the geophagic practices in the area. Additionally, the study revealed that geophagic consumers were mainly in the age of child bearing age group and reddish and yellowish soils were the most preferred. Furthermore, the results showed that geophagic consumers in the area generally consumed soil commonly because of cravings and pregnancy, however, those who were not pregnant also consumed soil. The respondents reported that they mostly consumed clay and this material was consumed in its dry state and mostly unprocessed, if processed, it would be baked. This geophagic material was mainly found in the wild (riverbed, valley etc.); it was also found that most of the soil consumers did not know that the substances they consumed could be harmful to them. Among those who knew the consequences of consuming the material stated that soil consumption causes constipation, tooth decay, body poisoning, and abdominal pains. The results from the control group, 83 women who do not practice geophagia, aged between 18 and above, analysed using chi-square revealed a significant association of age with consuming soils (p<0.05), while there was no association of income source (p>0.05) and educational level (p>0.05) with consuming soils. Chi-square (χ2) analyses further revealed that there was no association of knowledge on the harmful nature of the substance (p>0.05), frequency of getting infections (p>0.05) and experiencing chronic illnesses (p>0.05) with frequency of consuming soils. vii The results of geophagic soils revealed the absence of geohelminths ova in the entire geophagic sample. Meaning geophagic consumers in Siloam village are not at risk of acquiring geohelminths infection which may be of potential risk to human health. However, geophagic consumers may be exposed to various other potentially hazardous biological and non-biological soil contents. The results of the water samples revealed that most of the water samples in the areas where open defection is reported to be practised had higher composition of faecal and total coliform bacteria. The composition was above the South African recommended standard for negligible risk of microbial infection. This has caused a great threat to those who consume soil collected near water resources, especially from riverbed and those who also use these water sources on their daily basis. The study recommends that geophagic consumers should continue to bake their materials before consumption as it might reduce the bacteria and toxic substances found in soils. The study also recommends that the residents of Siloam be made aware of the potential health hazards that might be posed to soil consumers and the effects of practicing open defecation near community water resources as high level of faecal coliform (E. coli) were found in the water. / NRF

MESMEG / Department of Mining and Environmental Geology / Literature indicated that several mineralogical identification studies have been carried out on clays but few have focused on the characterisation of geophagic materials from South Africa. Large quantities of earth materials are consumed daily in Mashau Village, however, their mineral content and geochemical compositions had not been determined. Moreover, though the consumption of geophagic materials is very common in the village, the associated health implications had not been addressed. Thus, the main aim of the research was to mineralogically and geochemically characterise geophagic materials commonly ingested in Mashau Village and infer on possible health implications that could result from their consumption. Questionnaires were administered to geophagists in the study area with the aim of generating data on the prevalence of geophagia and the motivations for the practice. Geophagic soils and their parent rocks (for determination of provenance) were sampled and analysed for mineralogical and geochemical content. Geophagic soil samples were subjected to the following physicochemical analyses: colour, particle size distribution, pH, cation exchange capacity (CEC) and electrical conductivity (EC). An x-ray diffractometer (XRD) was used for mineralogical analysis while major oxides and trace elements abundances were determined using x-ray fluorescence (XRF) spectrometry and laser ablation inductively coupled mass spectrometry (LA-ICP-MS), respectively. Furthermore, provenance of the geophagic materials was determined using data obtained from mineralogical and geochemical analysis. Inferred health implications were based on the physico-chemical, mineralogical and geochemical data obtained. Outcomes of the questionnaire survey revealed craving to be the motivation for geophagia in Mashau Village. Although the practice seemed to be prevalent in females of certain ages, it was certainly not limited to gender, age, educational level or socio-economic status. Out of the 20 geophagic samples, 3 samples were brown, 2 had a strong brown colour and another 2 had a light olive brown colour. Other soil colours were less common, as each colour was only observed in one sample. The sand fraction dominated the samples; the clay content was low, giving the samples a sandy clay loamy texture. The pH of the soil ranged from being slightly acidic (5.4) to being slightly alkaline. The CEC values were very high ranging from 17 t0 109 meq/100 g. vii The EC values were also high (ranging from 11.2 to 245 μS/cm) indicating a high amount of soluble salts. Mineralogical analysis of geophagic soils identified quartz, microcline, plagioclase, hornblende, dolomite, muscovite, kaolinite, smectite, talc, anatase, hematite, ilmenite, chlorite and epidote with quartz and kaolinite being the dominant minerals. Actinolite, augite, chlorite, epidote, forsterite, magnetite, muscovite, plagioclase, quartz, sepiolite and microcline were the minerals identified in rock samples. Geochemical analysis for major oxides content (SiO2, TiO2, Al2O3, Fe2O3, MnO, MgO, CaO, Na2O, K2O, P2O5 and Cr2O3) indicated that both geophagic soils and parent rocks were mainly composed of silica and alumina. Trace elements geochemistry showed a depletion of LREEs and an enrichment of HREEs in geophagic soils. The results also revealed that the REEs were enriched in the bulk fraction than in the clay fraction. Relative to the Upper Continental Crust (UCC) compositions, the concentrations of trace elements in geophagic soils were generally low. Provenance determination results showed that geophagic soils in Mashau were derived from basalts and sandstones. Majority of the samples were formed as a result of intense weathering while some were as a result of intermediate weathering. The negative health implications of the studied materials could include perforation of the colon, damage of the dental enamel and anaemia. However, geophagic materials could also be a good source of mineral nutrients and beneficial for reduction of nausea during pregnancy. / NRF

MSc (Zoology) / Department of Zoology / The concept of taxonomic diversity has been widely used to investigate diversity patterns and the mechanism underlying community assembly. However, functional and trait diversity can further explain the factors driving community assembly because they capture different aspects of species ecological roles such as habitat requirements and resource use. To investigate the factors shaping community assembly along the elevational Soutpansberg transect, ants were used as a model study organism because they are widely distributed geographically, ubiquitous and play several important roles in ecosystems. Functional and taxonomic diversity patterns along the elevation, their drivers (seasonality, soil properties, temperature and habitat structure) were examined using a long-term dataset (8 years) collected seasonally. Morphological and physiological traits at a community level are quantified and their relationship to temperature, soil properties and habitat structure modelled. Traits were used to test the size-grain hypothesis, Janzen’s rule and Brett’s rule. Functional and taxonomic diversity had a humped-shaped pattern on the northern and a decreasing pattern on the southern aspect. However, taxonomic diversity did not decrease monotonically on the southern aspect. Functional diversity was mainly related to habitat structure and temperature while taxonomic diversity was explained by seasonality, soil properties and temperature. Functional and taxonomic diversity were positively related at a larger scale but habitat specific at a smaller scale. Taxonomic diversity explained more variation in functional diversity than habitat structure and their interactions. The results supported the size-grain hypothesis and Janzen’s rule but not the Brett’s rule. Patterns in taxonomic and functional diversity mirrored each other but were the result of different mechanisms. Temperature was however important for both measures. Incorporating functional diversity analysis into taxonomic diversity contributed significantly in understanding the different mechanisms underlying community assembly along the Soutpansberg transect. This together with trait responses to environmental variables such as a decrease in size with increased temperature could be used to model the responses of ant communities to global change drivers such as climate and land use change / NRF

MAAS / Centre for African Studies / Healing practices and health related rituals play a vital role in most religious groups including African Traditional Religion, Christianity, Islamic and Hinduism. This phenomenon of healing has been a challenge to religious institutions as well as African based churches. This study examined and analysed the healing practices within mega-churches in relation to the health related aspects. It appears that healing practices performed in those churches make them popular and enhance their growth in membership numerically. The study focuses on the philosophy and theological understanding of both mega-churches and mainstream churches. It is ostensible that healing, as a phenomenon, cannot be separated from core African culture, values and practices. Current church healing practices seems to be a more practical and accessible alternative way to deal with sickness as medical facilities has become inexorably costly especially to poor community who have no access to efficient medical amenities. Underprivileged members of society are drawn to religious healing practices because healers such as prophets, pastors and apostles dangle the capacity to heal people from all kind of ailments. Poor communities become a target because they are victims of government and the department of health malfunctions which are depicted by the poor and below standard medical services in those underprivileged communities. Most people in those communities believe that the above-mentioned emerging prophets and apostles from mega-churches are anointed and possess special power to heal them as well as to redeem them from life’s harsh realities. In the context of current healing practices, the researcher discovered that there is a need to probe and analyse the aforesaid practices particularly whereby healing seekers seems to have not receive what they anticipated from those mega-churches. The study exposes inappropriate healing dynamics conceived in the selected mega-churches within African tradition context. This study followed a qualitative approach, in which participants from both mega-churches and mainline churches were interviewed. The study further points out some perceived challenges affecting current healing practices in the selected mega-churches of Vhembe district of Limpopo Province. The study employed Interpretative Phenomenological Analysis strategy to analyse the data for the study. / NRF

DEd (Educational Management) / Department of Educational Management / The study examined challenges in the implementation of performance appraisal on educators in Shiluvana Circuit in Mopani District, Limpopo Province. The study focused on 5 principals, 5 deputy principals, 18 teachers, 1 IQMS circuit coordinator and 1 IQMS District coordinator who were selected purposively, as they were directly involved in teacher appraisal. The study is qualitative which used interpretive paradigm research and case study research design. Qualitative data was generated through face–to-face interviews, with the 5 principals, 5 deputy principals, 1 IQMS circuit coordinator and 1 IQMS district coordinator, focus group interviews with 18 teachers and documentary analysis. Thematic analysis was employed to analyse narrative data for the study. It was established that principals, deputy principals, teachers, IQMS circuit coordinator and IQMS district coordinator experienced challenges with teacher appraisal, challenges like inadequate commitment by teachers, inadequate trained principals, inadequate monitoring, lack of interest and backlog in teachers’ remuneration. The study recommends that principals, deputy principals and teachers be trained thoroughly for the effective implementation of the programme at schools, an expect official in IQMS to be permanently employed at circuit office for the successful implementation of the programme. Finally, informed by the conceptual framework of the study, it is recommended that the Accountability and Professional Development models for teacher appraisal be implemented in the circuit in order for all stakeholders to understand and effectively play their roles on teacher appraisal. To improve the current situation, cyclical stakeholders teacher appraisal model is suggested which suggests that IQMS structures to be set at national, provincial, district, circuit and school levels as substantive offices. IQMS structures to be trained by circuit on IQMS policy and implementation strategies using cascading approach. / NRF
