MA (African Studies) / Centre for African Studies / This study explored indigenous medicinal knowledge of Phonda in the Vhembe District. It has been noticed that phonda is becoming a scarce crop. The objectives entail seeking to solicit information on the uses of phonda, to understand the attitudes of local households towards phonda and to establish what can be done to restore the cultivation of phonda. The study used qualitative method involving unstructured interviews to collect and thematically analyse data. Purposive sampling and snowballing methods were used to make up the study sample. From literature, it is known that traditional health practitioners used phonda for treatment of certain diseases and illnesses. Phonda is no longer common, but the study sought to encourage the cultivation of phonda. The study employed an Afrocentric paradigm of social change as the conceptual framework. The study found that many households no longer plough phonda as they used to in the past. The study recommends that people should be educated on the importance of phonda to encourage them to plough it. Additionally, the researcher recommends further studies into different purposes of phonda and areas to boost its farming.

MGS / Institute for Gender and Youth Studies / Gender mainstreaming has been adopted as a strategy for promoting gender equality in institutions of higher learning worldwide, and not least in Africa. There are perceptions that most strategic higher positions in institutions of Higher learning are dominated by men while women are marginalized. This study therefore explored Gender Mainstreaming in institutions of higher learning. In particular, the study was based at a rural university in Limpopo, South Africa. The study was based on a Feminist Theoretical Framework, where a mixed method approach was embarked upon. The study involved a population of 840 participants who were sampled to 84. Purposive sampling was used to select 9 participants who were interviewed and stratified sampling was used to select a sample of 75 participants who were given questionnaires. The findings of the study are as follows: Males at the University of Venda continue to occupy higher echelons of power. Women continue to be under-represented in the positions of Deans, HODs, School Administrators and Directors. The university has strategies in place for female staff to acquire equal representation in senior management positions. Factors hindering the implementation of the 50/50 parity on gender stem from the lack of commitment from top management, and the stereotyping of women’s roles. Some respondents indicated that they do not know of the gender policy at the University of Venda. The university uses the Employment Equity Act of 1998, but, it is not clear whether line managers are aware how it should be implemented. Gender mainstreaming policy is feasible. The study recommends that there should be more gender awareness activities such as workshops, conferences, and symposia for workers and staff members in order to sensitize them about gender mainstreaming.

DEd (Educational Management) / Department of Educational Management / Performance of learners in Chemistry in South Africa has been below the international average. This study intended to investigate the management of high school learners’ academic performance in Chemistry as a component of Physical Science. The study employed mixed designs which are qualitative and quantitative. The population of this study comprised learners who were doing Physical Science, Physical Science teachers and school principals. The principals as participants were purposively sampled whereas teachers and learners were stratified random sampled. Data were collected through questionnaires which were distributed to learners and teachers, while school principals were orally interviewed. Data obtained from questionnaires were analysed using SPSS software. Qualitative data were analysed through identification of themes, development of codes and sub-themes. The improvement of teaching and learning will have a positive impact on the academic performance of high school learners in Chemistry. The findings showed that there are factors which affect the management of high school learners like (school location, inadequate physical resources, attitude and anxiety) contribute to the performance of learners in Chemistry. The findings also showed that factors influencing the academic performance of learners in Chemistry like (effective teaching, In-service Training of Chemistry teachers and Chemistry syllabus and content) contribute to the performance of learners in Chemistry. This study will give new insight to curriculum developers and implementers, and researchers regarding emerging issues on performance and influence the Ministry of Basic Education on policy formulation. Improved Chemistry performance will give learners opportunities to pursue science related courses in higher institutions of learning and middle level colleges.

MENVSC / Department of Ecology and Resource Management / Certain communities in Sekhukhune area are known to be practicing geophagia. Existing standard questionnaires as adopted to generate data on human geophagia included aspects on demography, socio-economics, cultural, ecological, physico-chemical aspects, indigenous knowledge and health effects of geophagic consumers. These data were gathered through distribution of questionnaires to 200 geophagic participants, of which 135 were from Ga-Nchabeleng Village and 65 from Mphanama Village. Both the Villages were based in the rural settlements in Sekhukhune area. In this study the behaviour of geophagic individuals was investigated and cytotoxicity of plant remains consumed in geophagic soils was evaluated for any toxicity. A total of 17 different geophagic sites were identified. Six geophagic sites each were from Ga-Nchabeleng Village and six from Mphanama Village. Five other sites were selected from sites where geophagia was not practiced and were recorded as the control sites. All the 17 soil samples were analysed using Munsell Soil Color charts for soil colour classification. Samples of plant remains were collected from the same geophagic sites where soil samples were collected. Due to similar plants and vegetation type from 17 different geophagic sites, a composite study was adopted. Geophagic consumers in Ga-Nchabeleng Village identified four plant species of plant remains consumed in the soil in the area and Mphanama village identified five species different from Ga-Nchabeleng plants. Samples of plant remains were grouped according to comparable features or characteristics. Sample 1 of plant remains was composed mainly of grasses; Cynodon dactylon, Aristida congesta and Eragrostis rigidior whereas sample 2 of plant remains was composed of Acacia plant; Vachellia tortilis. The two samples of plant remains were collected from Ga-Nchabeleng Village. Sample 3 of plant remains was composed of creeping, perennial weed herbs; Alternanthera pungens Kunth and Alternanthera lorentzii. Sample 4 of plant remains was composed of prominent woody plants; Combretum apiculutum, Kirkia wilmsii and Boscia albitrunca. Samples of plant remains 3 and 4 were collected from Mphanama Village study sites. Sample 5 of plant remains was the control site and composed mainly of Acacia plants; Vachellia nilotica, Acacia vii mearnsii and Vachellia tortilis and were collected from sites not used for geophagic practices. The plant remains parts mostly consumed were roots (50%) in Ga-Nchabeleng, whereas in Mphanama Village they were stems (54.5%) and the control site had leaves at 62.5%. The five samples of plant remains were recovered using physical separation method. The plant remains were washed and dried. Retch Muhle grinding machine was used to ground the samples. Methanol was used in the extraction of all the samples of plant remains. The result from the administration of the questionnaire revealed that geophagia in this area was practiced by both male and female Sepedi-speaking individuals. Ga-Nchabeleng Village had more female geophagic participants, whereas Mphanama Village had more males who have almost undergone secondary school. However, in general for the study there were more female geophagic consumers. Geophagic consumers ingest soil known locally as Mobu, Letsopa or Leraga collected mostly from the riverbanks, mountains/hills and valleys with only a few that indicated termite mounds. Geophagic consumers in the study used colour, among other things, to describe their soil of preference. The study consisted of 200 participants of whom 172 represented the geophagic group and 28 were the control group, aged between 18-65 years analysed using chi-square crosstabulation. There was no significant difference in human health effects associated with geophagia between the geophagic group and the control group. There was also no association established between soil consumption and other non-food substances between geophagic group and control group. Chi-square (χ2) analyses revealed a significant association of gender with geophagic habits (p<0.05), while there was no association of age, educational level, income source and marital status (p>0.05) with geophagic habits. Findings of the survey when two villages are combined revealed that more females (75.60%) practice geophagia compared to males (24.40%). The respondents from both study sites preferred digging technique when collecting the soil. It was established that craving was mainly the reason behind the practice in the study area. Hygiene and environmental conditions were not considered when mining viii geophagic soil as the majority of them used dirty utensils, hands for collection and non-sterile bags and tins for packaging. Some of the soils were collected close to waste dumping sites as seen whilst visiting geophagic mining sites. Majority of the consumers had little or no knowledge that the soil could be harmful or if it contained any contaminants. This sample of interviewees provided valuable information on human geophagic practices in Sekhukhune area. It became clear that this practice was entrenched in the cultural behaviour of people in the area and a need for educating them on health related aspects. The cytotoxicity of methanolic extracts of plant remains on HEK-293T cell line was evaluated using MTT (3-[4, 5-dimethylthiazol-2-yl]-2, 5-diphenyltetrazolium bromide) assay for cell viability. The 50% cytotoxic concentration (CC50) was defined as the compound’s concentration (500, 250, 125, 62.5, 31.25, 15.625 and 7.8125 μg/ml) required for the reduction of cell viability by 50%. Evaluation of cell viability showed the methanolic extracts of plant remains on HEK-293T cell line ranged in the order of plant remains extract=3>1>4>2>5 according to their cytotoxicity activities. Plant remains extract 3 from Mphanama Village showed high cytotoxicity with a CC50 of 13.75 μg/ml, followed by plant remains extract 1 at 16.68 μg/ml, plant remains extract 4 at 58.95 μg/ml, plant remains extract 2 at 92.75 μg/ml and the control at 251.4 μg/ml, respectively. In the study only the methanolic extract was investigated for cytotoxicity using HEK-293T cell line. Further research need to be conducted on the individual plants of each plant remains to be able to have conclusive results on the cytotoxicity profile. This will indicate which specific plant part is toxic or whether they exhibit a higher CC50 only when in combination.

MRDV / Institute for Rural Development / The study was carried out to assess the community-perceived determinants of access to land for development in Mutale Local Municipality. It was conducted in the Makuya and Mutele Traditional Authority areas of the former Mutale Local Municipality. All the views relating to access to land for housing, agriculture and business development expressed during the Vhembe District Land Development Summits and Forum meetings held in 2008, 2010 and 2014 were consolidated. Using this information, a questionnaire comprising entirely closed-ended answers requiring responses on a Likert-type scale of 1 (strongly agree) to 5 (strongly disagree) was prepared. The questionnaire was administered through focus group discussions in community workshops during which youth (male and female), women, men and community leaders were the respondents. Open-ended questions were also administered focusing on the factors hindering or enabling access to land, and solutions that the community perceived needed to be taken. Mean and mode for each response were calculated. Chi-Square tests for association were conducted to determine whether there was any association in the responses obtained from the traditional authority areas. Kruskal Wallis and Mann-Whitney tests were conducted to determine the level of agreement of perceptions respondents with Vhembe district land development summits resolutions among youth, adults and community leaders. There were no statistically significant differences (P > 0.05) in perception of issues relating to access to land for housing, agriculture and business development of land development. Thus, the issues are real and should form a solid basis for planning interventions that might unlock access to land for different types of uses. Moreover, improving transparency and deepening community participation and consultation over classification and sale of unoccupied land could minimise the likelihood of potential land conflict.
