- Description: An investigation was carried out on the implications of solid waste management on livestock health in selected abattoirs of the Eastern Cape Province of South Africa. The main objective of the study was to determine the effects of solid waste management on livestock health as well as to assess the perceptions of solid waste management among livestock owners. In this study, a questionnaire was designed to obtain information regarding farmer’s perceptions on solid waste and how it affects animal health, and active abattoir inspection were conducted to assess how solid waste affects the animal. The results revealed that most farmers practiced poor solid waste management as a result animals were exposed to ingestion of indigestible materials. This was confirmed on the basis that most farmers (99.2 percent) had no municipal dustbins in their areas, no recycling programmes (94.2 percent) and 51.7percent of the farmers disposed their litter in open land as a result most farmers (75.9percent) agreed that solid waste management was a problem in their areas. Due to poor solid waste management, 53.8 percent of the farmers confirmed that they have seen livestock ingesting indigestible materials such as plastics and 69.0 percent of the farmers suspected that ingestion of such materials caused some of the health issue experienced by animals on their farm. The active abattoir inspection revealed that plastics, wires, nails, ropes, stones, bones, cloths, hairs and polybezoars were frequently occurring in slaughter cattle stomachs particularly in the rumen and reticulum and in female and older cattle. As a result most affected cattle were in thin and average condition. The effect of indigestible objects on body condition score (BCS) and organ condemnation was determined using linear regression analysis test; where BCS and condemnation were the dependent variables and indigestible objects were the independent variables. The results revealed that some organs were condemned in affected cattle and the statistical analysis showed that there was no significant difference (p< 0.05) between the prevalence of indigestible materials and organ condemnation. However, there was a significant difference between the prevalence of indigestible materials and body condition score of affected cattle although they were coming from different farming systems. It was concluded that livestock health was affected by solid waste and recommended that practice of good animal husbandry and proper solid waste management be practiced to overcome the implications (poor body condition score) of solid waste in livestock. Furthermore, close cooperation between government extension officers, commercial and communal farmers in knowledge-sharing regarding health issues of livestock is recommended.

- Description: Over the years, human trafficking has become one of the fastest growing crimes in the world. According to a report of the United Nations Office on Drugs and Crime, Women and Children account for 75 percent of trafficked victims. Between 2007 and 2010, children accounted for 20 percent of the trafficked victims which is approximately 1343 children per year. Sadly, these statistics continue to rise annually. It is from this premise that no one can doubt the rationale behind the 2015 Immigration Regulations that affect children travelling in and out of South Africa. However, in terms of section 28 (2) of the Constitution of the Republic of South Africa, it is a prerequisite that in any matter affecting a child, the best interest of the child be of paramount importance. This mini dissertation seeks to establish whether these Immigration Regulations which initially came into effect in May 2014, are in the best interest of child travellers. This has been done by looking at the old system which regulated the movement of children; its loopholes and shortcomings, thereby establishing whether Regulation 6 (12) is a panacea or in fact the hallmark of a series of problems that have a detrimental effect on the well-being as well as the rights of the child. The research methodology is mainly based on a study of existing literature. This largely includes internet sources, national legislation, regional and international instruments as well as case law. The South African Immigration Act 2002 is the primary reference with regards to regulatory information. However, lessons are drawn from legislation from other jurisdictions, notably Zimbabwean Immigration laws as well as those of Namibia. This is because South Africa shares a border with Zimbabwe and it also has a historical connection with Namibia and has good relations with both States. The mini dissertation analyses the impact of the 2015 Immigration Regulations not only on children but on other sectors as well. Lastly, the latter makes recommendations on how to improve these Regulations without affecting the best interest of child travellers.

- Description: Expansion of woody vegetation results in the transformation of a grass-dominated ecosystem to a tree-dominated ecosystem causing land degradation in most semi-arid areas. The imbalance in the natural ecosystem between herbaceous plants and woody vegetation poses a threat to the natural environment. Such changes alter the flow, availability and quality of nutrient resources in the biogeochemical cycle. Most of the dominating woody plants are often unpalatable to domestic livestock. Therefore, the objective is to assess the spatial extent of woody vegetation over time. Knowledge of the spatial and temporal characteristics of woody vegetation dynamics will enable the development of management plans. These characteristics can be derived using remote sensing techniques which have become efficient in such studies. This study aimed to characterize woody vegetation dynamics along the route between Alice and King Williams’s town in Eastern Cape Province South Africa using Landsat data. This aim was achieved by focussing on three specific objectives. The first objective was to compare the performance of multispectral data and Normalized Difference Vegetation Index (NDVI) data of Landsat imagery in mapping woody vegetation cover. The second objective was to investigate the effect of the spatial resolution of remotely-sensed data on discrimination of woody vegetation from other land cover types. The third objective characterised woody vegetation dynamics between 1986 and 2013/2014 using the results from the first objective. The study used Landsat imagery acquired in November or February of 1986, 1994/1995, 2002/2003 and 2013/2014. Due to lack of data which covered the study area two separate dates (November and February) where used for the study resulting in naming the study area western and eastern parts. Unsupervised classification was performed on the multispectral, NDVI and pan-sharpened images to generate four generic land cover classes, namely water, bare land, grassland and woodland. Accuracy assessments of the classified images was done using error matrix. The results showed that the classification based on NDVI images yielded a better overall accuracy than the classification based on multispectral images for the western (83 percent and 75 percent, respectively) and eastern (82 percent and 76 percent, respectively) parts of the study area. Similarly, pan-sharpening resulted in better overall classification accuracy than multispectral, but comparable to the classification of the NDVI images for both the western (82 percent) and eastern (83 percent) parts of the study area. Remote sensing is an effective tool in assessing changes in the physical environment. Landsat imagery is suitable in assessing land cover dynamics given the long-term and free availability of the image. In addition, the large spatial coverage it provides, enables Landsat data to be used on studies that have wide spatial coverage. Classification for the purpose of time-series analysis was then performed on the NDVI images of each date (1986, 1994/1995, 2002/2003 and 2013/2014). Both woody vegetation and grassland experienced changes from 1986 to 2013/2014 with grassland occupying (75 percent) compared to woodland (17 percent) in 1986. In the year 2013/14 grassland occupied 32 percent and woodland occupied 51 percent of the study area. The increase in woody vegetation in the study area can be attributed to livestock rearing and migration of people from the rural to urban areas post-Apartheid. The study output will aid in the development of a database on land cover distribution of the area between King William’s town and Alice town, providing useful information to decision-making and further studies on woody vegetation.

- Description: Concentrating on the Katberg and Burgersdorp Formations, this research examined the sedimentary environments inter alia by conducting heavy mineral analysis, interpreting provenance and determining stratigraphic interrelationships of the two formations in the Tarkastad Subgroup (Beaufort Group, Karoo Supergroup) around the town of Whittlesea in the Eastern Cape Province of South Africa. It has been observed that the strata of the Katberg Formation are dominated by sandstones of a braided river system. On the other hand, the Burgersdorp Formation comprises mainly dark greyish-red mudstone, red shale with subordinate siltstone and red sandstone deposited on floodplains and channels of meandering rivers. The Katberg Formation becomes progressively less arenaceous to the north of the study area until it is virtually indistinguishable from the overlying Burgersdorp Formation. Dolerite dykes and sills that intruded the Karoo Supergroup disturbed and baked the sedimentary strata of the Tarkastad Subgroup as well as other Karoo successions. The Katberg formation is mostly found in elevated areas, commonly metamorphosed and capped by dolerite sills while the Burgersdorp is found in low lying areas and is less metamorphosed or not metamorphosed at all. Lithologies of the two formations and the Karoo dolerites have been geologically mapped and the interfingering relationship between the Burgersdorp and Katberg Formation is also shown on the map. Horizontal laminae, planar bedding and planar and trough cross-bedding characterise lithofacies in the two formations. The fossil hunt done during the course of the study did not yield any positive results in both formations. Initially, the pebbles from outcrops of the Katberg Formation in the East London area were described in hand specimen by Mountain (1939). This study took it further with petrographic- and modal analysis as well as grain size analysis for the sedimentary pebbles. Microscopic studies done on the rock samples collected in the study area revealed quartz and feldspar as the dominant constituents. Most of the feldspar is hazy as a result of dissolution and alteration to clays. Sparse sedimentary rock fragments and quartz overgrowths in some of the rocks and grains respectively, indicate phases of recycling from older sedimentary sources. Furthermore, the samples have a wide range of grain sizes, sorting, grain shapes and classification categories. Textural attributes of sediments such as mean grain size, sorting, skewness and kurtosis were used to characterise the nature of the transport processes and to reconstruct the depositional environment of the sediments. The sandstones of both the Katberg and Burgersdorp Formations are medium-grained and moderately sorted to moderately well sorted but the pebbles are very coarse- to coarse-grained. Deducing sediment provenance from the final product of a basin fill is anything but straight-forward because rocks break down and unstable minerals change during transportation along the pathways from source to basin and afterwards during diagenesis. Heavy mineral studies coupled with geochemical sandstone analysis were used to unravel the sources of sediments. Among the heavies found were opaque and non-opaque minerals which are highly resistant to weathering with zircon being the most dominant. The heavy mineral grains vary in shape from subround to angular-subround in shape. The integrated results of petrography, XRD, XRF and SEM/EDX were used to identify the source rock character and to evaluate the relative role of tectonics and climate in determining the geochemical composition of the Katberg and Burgersdorp sandstones. Sandstone composition was used to decipher the provenance and tectonic setting of source areas by standard triangular QtFL and QmFLt diagrams, tectonic setting discrimination diagrams and source rock composition diagrams to characterise the source rocks.

- Description: Adsorption equilibrium and kinetics of methylene blue (MB) onto silica gel and aluminum pillared montmorillonite was studied in a batch system. Variables of the system include contact time, salt concentration and initial methylene blue concentration. Langmuir and Freundlich isotherm models were applied to experimental equilibrium data of methylene blue adsorption. Both models were suitable for the parameters. The advantage of silica gel as applied to water treatment is its high porosity when compared to aluminum pillared montmorillonite clay. Water molecules adhere to the silica gels surface because it exhibits a lower vapour pressure than the surrounding air. When equilibrium of equal pressure is reached, no more adsorption occurs. Thus the higher the humidity of the surrounding air, the greater the amount of water that is adsorbed before equilibrium is reached. The increase in pressure loss on the silica gel filters is 1.5 - 2.0 times smaller than in the case of sand filters, Lorenc (2007).

- Description: The main aim of this research is to synthesize Ni(II) and Pd(II) dithiocarbamate complexes and use them as single source precursors for the synthesis of NiS and PdS nanoparticles and metal sulphides potato starch nanocomposites. Four dithiocarbamate ligands were synthesized and characterized using elemental analysis and spectroscopic techniques. The ligands were used to prepared homoleptic Ni(II) and Pd(II) complexes of the dithiocarbamate ligands. The metal complexes were characterized with elemental analysis, UV-Vis, FTIR and 1H-NMR spectroscopic techniques. Conductivity measurements indicate that all the complexes are non-electrolytes in solution and results from the electronic spectra studies confirmed the proposed 4-coordinate square planar geometry around the metal ions. The nickel complexes showed d-d transitions around 477 nm while in the palladium complexes, no d-d transitions were observed but the compounds showed strong metal to ligand charge transfer transitions. From the FTIR spectra studies, it can be confirmed that the complexes were successfully synthesised because all peaks of interest were observed at expected regions from the literature. The νC-N was observed around 1469-1495 cm-1, νC=S around 1101-1188 cm-1 and νC-S around 738-1060 cm-1 for both Ni(II) and Pd(II) complexes. νNi-S was observed around 375-543 cm-1 and νPd-S around 529-545 cm-1. The FTIR also confirmed that the dithiocarbamate ligands act as bidentate chelating ligands through the sulfur atoms. The complexes were used as single source precursors and thermolysed in hexadecylamine (HDA) at 220 °C to prepare four HDA-capped nickel sulfide nanoparticles and four palladium sulfide nanoparticles. The as-prepared nanoparticles were studied with optical absorption spectra, photoluminescence, powder X-ray diffraction (PXRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS). The optical studies results showed that NiS have large band gaps that are greater than that of the bulk, therefore they are found to be blue shifted relative to the bulk, which shows that they have small particle size and thus confirming their quantum confinement effect. PL spectra reveal that the emission peaks are red shifted compared to the absorption band edges of the nanoparticles. The XRD patterns confirmed the formation of cubic and rhombohedral phase for NiS nanoparticles and cubic phase for PdS nanoparticles. SEM images of both NiS and PdS show uniform surface morphology at low and high magnification with different shapes. EDS analyses confirmed the presence of Ni, S, and Pd in each of the spectrum indicating that the nanoparticles were successfully synthesized. TEM images showed that the synthesised nanoparticles have uniform and narrow size distribution with no agglomeration. The sizes of the NiS nanoparticles were found to be in the range of 12-38 nm for NiS1, 8-11 nm for NiS2, 9-16 nm for NiS3 and 4-9 nm for NiS4. The TEM images for the as-prepared PdS nanoparticles showed that the average crystallite sizes are 6.94-9.62 nm for PdS1, 8-11 nm for PdS2, 9-16 nm for PdS3 and 4-9 nm for PdS4 respectively. The nanoparticles were used to prepare potato starch nanocomposites and SEM images indicate that the surface morphology of starch polymer nanocomposites compose of potato starch and few particles in between the pores of the matrix, this is due to the small ratio of nanoparticles used.

- Description: Rape is a violent crime marked by underreporting and low conviction rates. Notwithstanding the fact that most rape laws have been made to be gender-neutral, the statistics of rape are still devastatingly high even on a global scale. The majority of the victims are still predominantly females especially in the context of acquaintance rape. It is an uncontestable fact that rape usually occurs in secret making it possible for one to falsely accuse another and effectively rendering it difficult to refute. In light of this, victims who have managed to reach the courts have come face to face with a myriad of stereotypical beliefs and rape myths about rape victims. These have dealt a blow to their cases once their credibility is doubted because they may have exhibited behaviour that does not match with the classic or real rape victim as expected by the society. However rape is an egregiously unique crime that presents with serious psychological issues for the victim. As such it is possible for a rape victim to exhibit counterintuitive behaviour that can only be sensibly explained by an expert who has delved in human behavioural sciences. The alleged victim will be questioned on things like lengthy delay in reporting, returning to the scene of the crime, asking for taxi money the morning after the rape or even failing to scream and fight off the alleged assailant. Unfortunately, the psychological effects of rape have more often than not been overlooked in our criminal justice system giving way for blame shifting in that the female victim is called upon to account for why the rape may have happened to her. These psychological reactions, responses and counterintuitive behaviour have been characterized as Rape Trauma Syndrome by specialists in psychology and psychiatry. In the context of this study, Rape Trauma Syndrome is a form of expert opinion evidence which is relevant, helpful and necessary because it can dispel rape myths and stereotypical beliefs about rape victims by educating the courts about the psychological reactions of rape victims. Against this backdrop, this research project investigates the utility of Rape Trauma Syndrome evidence in dispelling rape myths in rape trials, focusing especially on the admissibility and use of that syndrome as evidence in other jurisdictions at the level of comparative analysis in order to establish whether it can be utilised in the South African context.

- Description: This study focused on the technical and institutional constraints faced by the vegetable co-operatives with regard to the impact on productivity. Vegetable co-operatives have no access to markets due to their poor performance on productivity and poor quality produce resulting to low prices for the produce such that they cannot compete in a market economy. In this study, the data was drawn from a sample of thirty vegetable co-operatives in the Buffalo City Metropolitan Municipality (BCMM) of the Eastern Cape; obtained through focus group discussions and interviews from each cooperative. The objectives of the study are to measure the productivity of vegetable co-operatives using Total factor productivity analysis (TFP) and profitability of vegetable co-operative using Gross Margin (GM). Followed by the descriptive statistics in identifying and assessing the socio-economic characteristics as well as coping strategies adopted by vegetable co-operatives in BCMM where percentages, means and tables are used looking at the highest frequency. The results show that the vegetable co-operatives in the BCMM are not productive and profitable due to major constraints experienced by co-operatives such as lack of market, information, trainings and business skills, capital, infrastructural facilities, effective extension services that all leads to poor produce quality. Co-operative is said to be profitable and viable if total revenue is greater than the total variable cost which makes the gross margin positive. In this case, the total gross margin is negative. The results showed that the production costs, maintenance (tractor hire, generator hire and servicing) and electricity costs were the major costs incurred in the production of vegetable by the co-operatives.

- Description: This study is an investigation of terrorism as a contributory factor to state failure in Somalia with specific reference to Al-Shabaab, using Huntington‟s Clash of Civilizations theory. It utilises both primary and secondary sources of data. The study found out that Somalia had been a failed state even before the birth of Al-Shabaab. However, the activities of Al-Shabaab perpetuated state failure in Somalia. These activities included bombings, small arms attacks, executions, siege, kidnappings, hijackings and looting. The study also found out that Al-Shabaab regularly conducted incursions in neighbouring countries and all these activities destabilised Somalia politically and perpetuated state failure. However, the study also found out that there were other factors that contributed to Somalia‟s state failure some of which were clan rivalry, civil war, warlordism, piracy, poverty and religion. Despite all these, the study noted that there were various actors involved in containing the terrorist activities of Al-Shabaab. These actors included the Transitional Federal Government, Kenya, the African Union, the United Nations and the United States. The study recommends that dialogue between the TFG, the clan structures and Al-Shabaab is the most viable path to sustainable peace in Somalia.

- Description: The study aims to evaluate the biomass production and nutrient content and silage quality of perennial ryegrass (Lolium perenne (L)), cocksfoot (Dactylis glomerata (L)) and tall fescue (Festuca arundinacea (Schreb)). Six varieties were used, two for each species. A completely randomized block designed replicated three times was conducted at University of Fort Hare Research Farm during 2014-2015 growing season. The plots were harvested at four-week interval (post emergency) for one year. Biomass yields were measured for fresh forage and dry matter yield. Duplicated samples were then dried, milled and analyzed for chemical and mineral composition (CP, NDF, ADF, and ash, Ca, P, K, Na, Mn, Cu, Zn and Fe) for only winter season. In addition the grasses were ensiled and the silage was analyzed for its fermentation parameters and nutrient content (lactic acid, pH, DM, CP, NDF, ADF, and ash, Ca, P, K, Na, Mn, Cu, Zn and Fe). Biomass results showed significant differences (P < 0.05) between season and varieties. On average Tall fescue varieties Jessup (13741.67 FM kg/ha), Alix (12007.78 FM kg/ ha) and Ryegrass varieties Samson (11597.22 FM kg/ha) and Nui (10591.67 FM kg/ha) had the highest fresh biomass yield. Similarly, Tall fescue varieties Jessup (2833.06 DM kg/ha) and Alix (2708.3 DM kg/ ha) and Ryegrass varieties Samson (2169.44 DM kg/ha) and Nui (2169.67 kg/ha) had the highest dry biomass yield. Throughout the year the average biomass yield was significantly different among species (P< 0.05). During summer and autumn Tall fescue varieties Jessup and Alix gave the highest dry matter yields of 3855.5 to 1977.8 DM kg/ha, and 3877.8 to 1900 DM kg/ha, respectively, and followed by Cocksfoot 2400 DM kg/ha. Ryegrass had the highest dry matter biomass yield in winter (2975 DM kg/ha) and the least in summer (977.75 DM kg/ha). There were no significant (P>0.05) differences on the chemical composition (CP, NDF, ADF, and ash) and mineral composition (Ca, P, K, Na, Mn, Cu, Zn and Fe) of the six varieties. The grass silage results showed significant differences (P< 0.05) among the six varieties for moisture content. Perennial ryegrass variety Nui (66.76 percent) had low moisture content than the other grass silages. The different varieties had no significant effects (P>0.05) on chemical composition (CP, NDF, ADF, and ash) and mineral composition (Ca, P, K, Na, Mn, Cu, Zn and Fe). It is concluded that the biomass production of the six varieties of three grass species was different throughout the year under irrigation hence Ryegrass and Tall fescue are recommended for dairy farmers in the region for all seasons. It can be concluded that there is no difference with respect to fermentation characteristics and nutrient content among the varieties of the grass species.

- Description: An important trend in fuzzy group theory in recent years has been the notion of classification of fuzzy subgroups using a suitable equivalence relation. In this dissertation, we have successfully used the natural equivalence relation defined by Murali and Makamba in [81] and a natural fuzzy isomorphism to classify fuzzy subgroups of some finite abelian p-groups of rank three of the form Zpn + Zp + Zp for any fixed prime integer p and any positive integer n. This was achieved through the usage of a suitable technique of enumerating distinct fuzzy subgroups and non-isomorphic fuzzy subgroups of G. We commence by giving a brief discussion on the theory of fuzzy sets and fuzzy subgroups from the perspective of group theory through to the theory of sets, leading us to establish a linkage among these theories. We have also shown in this dissertation that the converse of theorem 3.1 proposed by Das in [24] is incorrect by giving a counter example and restate the theorem. We have then reviewed and enriched the study conducted by Ngcibi in [94] by characterising the non-isomorphic fuzzy subgroups in that study. We have also developed a formula to compute the crisp subgroups of the under-studied group and provide its proof. Furthermore, we have compared the equivalence relation under which the classification problem is based with various versions of equivalence studied in the literature. We managed to use this counting technique to obtain explicit formulae for the number of maximal chains, distinct fuzzy subgroups, non-isomorphic maximal chains and non-isomorphic fuzzy subgroups of these groups and their proofs are provided.

- Description: Agricultural development is back on the development agenda. Even though the smallholder farmers are in the majority and at the forefront in terms of food production and agriculture being the backbone of the economy of Zimbabwe, there is no clearly defined policy on smallholder agriculture in Zimbabwe. The food insecurity has remained a continuous challenge for the rural poor in Zimbabwe. This study investigated the contribution of smallholder agriculture to food security with particular reference to the Masvingo province. The study employed qualitative method of research entailing extensive review of literature as a method of data collection. The study utilized the modernisation theory and sustainable livelihoods framework to illustrate smallholder agriculture and food security nexus. The study revealed that smallholder agriculture is the best option for addressing food security since agriculture is considered the main livelihood strategy for small scale farmers in Zimbabwe. There is general scholarly consensus that the main cause of food insecurity in Zimbabwe is a decrease in smallholder agriculture productivity. The study revealed that poor infrastructure , limited access to credit, limited access to inputs, poor investment in human development, limited access to markets and harsh climatic conditions weaken the capacity of small scale farmers to improve food security. Key recommendations are that supportive institutions need to be put in place to strengthen the smallholder farmer’s capacity to improve food security in Zimbabwe.

- Description: The purpose of this study was to assess the effectiveness of internal financial controls with specific reference to the Eastern Cape provincial department of basic education. A self-administered questionnaire was used to collect data. The questionnaire was filled by the respondents who are directly involved in processing payments and procuring for the departments. The findings have shown that Internal control system does exists within the department however the implementation and monitoring of its effectiveness needs to be strengthened. The findings show that the internal control system have an important role to play in attaining desired positive results within the department. Internal control effectiveness is one of the most important aspects in any organisation, whether in a private sector or in the public sector. It determines the stewardship of an entity’s management. The PFMA states that the accounting officer of a department must ensure that that department has and maintains effective, efficient and transparent systems of financial and risk management and internal control. If public officials could strictly adhere to the stipulated internal controls, there will be a positive response to accountability and also in service delivery as expected by the citizens. Public accountability gives a reflection on how does the entity conducts its business affairs in terms of adhering to the norms and standards as prescribed by the law and whether there are any strong controls to prevent acts of fraud and corruption.

- Description: This dissertation is about the National School Nutrition Programme (NSNP) in South Africa. This Programme was introduced by government in 1994 with the aim of alleviating poverty; unemployment and improving learning capacity of children. Specifically, it is intended to help poor children and to empower poverty-stricken communities, particularly in the rural areas across all the nine provinces. The focus of this study is on the investigation of effectiveness and efficient management of the Programme in the Eastern Cape Province, with specific reference to Mhlontlo District. Mhlontlo district is one of the predominantly rural areas in the province of the Eastern Cape, a remote area characterized by high levels of poverty and unemployment, and low levels of infrastructural developments. Surrounding Schools in the area are also affected by these problems. Learners at these schools are from poor families. It is for this reason that this scheme becomes important as it is most needed and, to effectively and efficiently realise its intended objectives, it must be properly managed. The main theme of the study revolves around effective and efficient service delivery that must be taken as the first priority in the management of NSNP. Factors that contribute to efficiency and effectiveness must be taken into consideration by all stakeholders and are outlined as follows: The aims in this study is to assess the effectiveness of management of the National School Nutrition Programme at Mhlontlo district in the eastern Cape, to identity shortcomings in the management of the Programme and to suggest possible remedies to improve the management of the Programme to effective service delivery. Against the background of the problem statement, the following questions were posited. How can the management of the National School Nutrition Programme with specific reference to Mhlontlo district be enhanced to ensure that its intended objectives are realized? What effect will improved management have on service delivery in the National School Nutrition Programme? And how will adherence to the Batho Pele Principles improve service delivery in schools with regard to the National School Nutrition Programme? The target population in this study was the learners, teachers and community of Schools around Mhlontlo District whose children are being catered for at school as respondents. Statistics of learners who are beneficiaries of this programme were obtained from surrounding Schools. The percentage of the response to the questions led to the results that services are not delivered as effectively as expected. The study concluded by recommendations of what national and provincial department of Education are required to do together with the school, service providers and the community in order to improve service delivery in schools that participate in the NSNP. Finally, the NSNP is for the deprived citizens of South Africa. The onus is on the community of Mhlontlo District, service providers, teachers and education authorities responsible for the NSNP to work together to make the programme effective for advancing the development of young people.

- Description: This study was conducted in one of the education districts in the Eastern Cape Province of South Africa. The purpose was to analyse the effectiveness of the concrete/semi-concrete/abstract (CSA) approach and drill-practice instructional strategies on Grade 10 learners’ ability to simplify addition and subtraction of algebraic fractions. The following two objectives were set. First, to identify the learners’ challenges in studying addition and subtraction of algebraic fractions in grade 10; and second to analyse the effectiveness of the CSA approach and drill-practice instructional strategies on Grade 10 learners’ ability to simplify addition and subtraction of algebraic fractions. Both threshold concepts and troublesome knowledge, Polya’s problem-solving techniques, CSA Approach theory and Drill-practice theory were all pertinent as a theoretical framework for the study. Positivism research paradigm was adopted for the study and it afforded the researcher opportunity to employ quantitative research approach. Based on the research question of this study, an experimental design was chosen as a suitable descriptive design. Purposive sampling method was used to select three schools which involved 135 grade 10 mathematics learners. Stratified random sampling method was thereafter employed to select 45 learners from each school for the study. The learners were grouped in each school as top, average and weak based on their performance in Algebra in term one. Pre-questionnaire and post-questionnaire were used to obtain data regarding challenges learners experience in simplifying addition and subtraction of algebraic fractions. Ethical clearance from the relevant school and university authorities were obtained. On the first two days, the researcher briefed the school authorities and learners and explained to them the purpose and details of the study. Day three was used to administer the pre-questionnaire test, thereafter, the next ten days were used to teach addition and subtraction of both numeric and algebraic fractions with same and different numerators and denominators. The next two days were used for revision and the last day was used to administer the postquestionnaire test out 25 marks. The respondent rate was 98.5%. The data collected were analysed by using SPSS version 16.10. Both descriptive and inferential statistics were used to analyse the data. The pre-questionnaire scores revealed that majority of the learners’ perceived fractions as two separate entities and as a result add or subtract numerator to numerator and denominator to denominator. It was also discovered that learners had a challenge in finding LCM of algebraic fractions. A t-Test for independent means was used to test the following hypotheses at 𝛼 = 0.05: 𝐇𝟎: The CSA approach and drill-practice intervention has no significant effect on Grade 10 learners’ ability to simplify addition and subtraction of algebraic fractions; 𝐇𝟏: The CSA approach and drill-practice will significantly enhance Grade 10 learners’ ability to simplify addition and subtraction of algebraic fractions. The t-Test revealed a p-value of 0.139 which was statistically significant at 𝛼 = 0.05. Therefore, the researcher rejected the null hypothesis and concluded that the CSA approach and drill-practice have significantly enhanced the Grade 10 learners’ ability to simplify algebraic fractions.

- Description: Prompted by the various advantages presented by entrepreneurship, there has been an increase in studies investigating the factors that could influence entrepreneurial establishment and success. The purpose of this study was to determine whether emotional intelligence could stimulate entrepreneurial interest, thereby contributing to the literature on antecedents of entrepreneurship. This study tested the various socio-demographic characteristics of the sample and how each variable influenced entrepreneurial intent and emotional intelligence. A self-administered questionnaire was distributed to 385 students in the Eastern Cape Province using the purposive sampling method. Correlations, simple linear regression and multiple regressions were computed to test the hypotheses using the SPSS data analysis package. The findings of the study showed that there is a direct relationship between emotional intelligence and intention to become an entrepreneur. Furthermore, socio-demographic factors examined showed immense relevance to the development of entrepreneurial intent. As such the study suggested that apart from developing an effective entrepreneurship education program open to all individuals with a keen interest in the subject irrespective of academic merit; educators should create a learning environment that encourages effective expression and use of emotions to nurture the emotional intelligence of students. Moreover, mentorship relationships between students and local entrepreneurs should be highly encouraged.

- Description: A country which prioritises in investing in human capital is believed to be a wealthy nation, meaning that the amount devoted to education and health sectors cannot be considered too much. The purpose of the study is to investigate the impact of human capital investment on economic growth, the case of South Africa. The study used time series data covering the period 1984-2014 to assess the impact of human capital investment on the economic growth of South Africa. The autoregressive distributed lag (ARDL) model and the error correction model (ECM) were employed in estimating the long run and short run relationship among variables of the study. The results of the study concluded that there is a positive long run relationship between total human capital investment (THCI) and South African economic growth. The results were in line with the hypothesis of the study and some empirical literature used. However, in the short run the results proved that there is no relationship between total human capital investment and economic growth in South Africa. Moreover, FDI and gross fixed capital formation proved to have a long run relationship with economic growth except exchange rate. The study recommends that the government should continue to devote most of its budget to human capital investment as it positively accelerates the economic growth of the country.
