- Description: The Department of Water Affairs as of late reported plans to build two substantial stockpiling dams in the Mzimvubu Catchment. The Mzimvubu stream basin is probably one of most prominent and undeveloped basin in South Africa. This is notwithstanding high yearly rainfall, high ecological status, high tourism potential, and appropriateness for afforestation, dryland/rainfed and water system agribusiness. Hence, the Department of Water Affairs researched the capability of building a multipurpose dam in the Mzimvubu catchment to catalyse financial and social improvement. The proposed dam will be based on the Tsitsa River. Often, scientific studies related to dam construction concentrate more on discovering the most, in fact, accessible place to construct it, than on the long haul socio-natural issues that come in its preparation. The water quality of the Tsitsa River, its tributaries and the underground drinking water sources within the Mzimvubu catchment are most likely to change once the dam wall is completed. Surface water resources are susceptible to chemical, physical, microbiological contamination and the so-called emerging pollutants either, through human or natural activities. A comprehensive baseline study on the water quality of the Mzimvubu water resources regarding traces of emerging pollutants and water quality determinants (physical, chemical and microbial) pre-dam construction is therefore essential. The objective of the water quality section of this study was to perform an in-depth analysis of water quality in the study area to form a baseline for future studies on how the built dam may affect these. The approach was to assess the spatial and seasonal variations of the pollutants (pharmaceuticals and pesticides) and water quality determinants for all water sources most likely to be affected by the development of the dam. The fitness-for-use and compliance assessments were conducted to assess if the current water resources are fit-for-use for various categories of use and if they comply with various water quality standards and guidelines as determined by the Department of Water Affairs and Forestry. Department of Water Affairs and Forestry is the overseer of South Africa's water assets, and its central goal is to keep up the fitness-for-use of water on a sustained basis. Water samples (500ml) were collected from sixteen (16) sample points, ranging from the proposed mouth of the dam to the N2 bridge point of the Tsitsa River. Points were selected where the Tsitsa River was accessible using the dam project development roads or where tributaries to the Tsitsa River were accessible using dam development roads. Taps/groundwater sources were sampled from the five selected villages. Monthly samples were collected upstream and downstream of the proposed dam wall, from June 2015 to April 2017.Seventeen (17) water quality indices were therefore analysed at sixteen sampling sites, over a two year period. The AB SCIEX TripleTOF™5600 LC/MS/MS was used to screen for pharmaceutical and pesticide pollutants. All the water quality indices were analysed using the AL400 Aqua lytic photometer, and the microbial analysis was done using the Rand Water Method Number 1.2.2.09.1 for enumerating the amount of E. coli and coliforms in the water samples (Rand Water, 2010f). The South African Water Quality Guidelines, Volumes 1 to 7 (DWS, 1996a-g) were used to assess the fitness-for-use of the water sources. To confirm the compliance of the water resources to various standards and guidelines, the water quality data were assessed against international and national guidelines and standards i.e. the WHO guideline, South African water quality guidelines (domestic, irrigation, livestock and watering, aquaculture, and aquatic ecosystems), and the SANS: 241 (2015) standard for drinking water. Non-parametric statistics were utilised to ascertain the changeability, which is a measure of how water quality may vary after some time. With non-parametric insights, the interquartile extent, which lies between the 25th and the 75th percentile, was utilised to depict inconstancy. The median value (50th percentile) was used as an indication of the central tendency or average. The 90th percentile was included as it can be used to assess the frequency of excursions into higher and possibly unacceptable water quality conditions. 3D Sigma plot was used to graphical present the spatial and seasonal variations of water quality indices and emerging pollutants against their concentrations. Fundamental statistical properties and correlations of water quality variables from the Tsitsa River, Tsitsa River tributaries and the drinking water sources were examined using SAS descriptive statistics. The water quality was determined to be of relatively sound quality, based on the comparison with guidelines and standards for the various intended uses, even though some of the water quality determinants were non-compliant and were “unacceptable” regarding fitness for purpose. The water quality of the Ntabalenga dam would most probably be affected by natural influences (for example rainfall, weathering and geological composition) and anthropogenic factors through non-point source pollution from agriculture activities, human settlements (pit latrines and open defecation) as well as industrial activities in the Maclear and Tsolo towns (wastewater treatments plants effluent, hospital effluent). The Tsitsa River had the highest number of non-compliances, especially to the World Health Organisation and Department of Water and Sanitation aquaculture guidelines. Therefore, the Tsitsa River’s water quality would be a significant factor that could compromise the water quality of the water collected in the dam. The human settlement conditions and agricultural inputs seem to be the factors contributing most to contamination of the surface water of the catchment area. The lack of sanitation systems and facilities means that community members have to use the bush and rivers for ablutions, thus contributing to microbial contamination of the environment. The direct application of manure and fertilisers on the fields by farmers further exacerbates microbial contamination and high nutrient inputs into the environment as observed in elevated microbial and phosphate contaminants during the study period. The data obtained from the analysis of pesticides and pharmaceuticals confirmed the contamination of the drinking water sources, the Tsitsa River and its tributaries with pesticides and pharmaceuticals through non-point source pollution. The origins of these pharmaceutical contaminants were identified as the pit latrines, open defecation and wastewater treatment plant effluent, while agricultural application of pesticides was identified as the source of pesticides in surface waters. If not monitored closely, the presence of these emerging pollutants will negatively affect the quality of the dam water both at spatial and temporal scales once the dam wall is completed. Pit latrines and wastewater treatment plants are a significant source of non-point source pollution. The results of this study will add to the ongoing efforts on water quality remediation by recording the spatial and seasonal variations in water quality across various water sources within the study area. The study also provides a baseline for future water quality fitness-for-use and compliance assessments. By these findings and conclusions, it is recommended that a long-term continuous monitoring programme be implemented, especially in areas where increased agricultural activities have been observed. Monitoring should be implemented for the Tsitsa River, its tributaries, and selected drinking water sources which showed the highest number of non-compliances and microbial contamination. All anthropogenic activities in the catchment areas of these sources, both upstream and downstream of the proposed dam wall, must be monitored and strictly managed to prevent and mitigate their possible impacts. Specific emphasis should be placed on agricultural development, which should be controlled to ensure sustainable livestock and cropping practises. Sanitation facilities, systems and community programmes should be put in place to minimise microbial contamination. It would be beneficial for the Department of Water and Sanitation office responsible for the Mzimvubu water resources to establish a central database for all information concerning the water quality of their water resources including the findings in this report. The database must be freely accessible to the residents of the Mzimvubu catchment.

- Description: This study focused on the strategies teachers use to enhance grade 7 learners’ reading comprehension skills in English First Additional Language at Fort Beaufort District. This study was impelled by low performance of learners in English language, where learners were unable to read and answer questions promptly due lack of understanding what they read. This study is qualitative in approach and underpinned interpretive paradigm position. Fort Beaufort Education District used as a case study whereby four schools were purposively selected and each with six grade seven learners, teachers and Subject Advisor. Qualitative data was gathered through semi-structured interviews, focus group interviews, observations and documents analysis. Interviews and focus groups discussions were taped, transcribed, analysed and the data was categorised into themes. The findings of this study disclosed the weak correlation between teachers’ knowledge and teaching practices and lack of support from the district. The participating teachers had limited understanding of reading comprehension strategies; as a result, they regarded teaching reading comprehension as a challenge since they do not know what comprehension strategies are, and how to apply them. Teachers lack theoretical knowledge and practice concerning the teaching of reading for comprehension resulted to a negative attitude and a total neglect towards teaching reading for comprehension. The participants showed dissatisfaction with the intervention of the Department of Education and the policies they impose on them. The Curriculum and Assessment Policy Statement has no clear guidelines on how to teach these strategies of reading comprehension, rather it places reading comprehension under three phases, namely: Pre-reading, During- reading and Post-reading. As they lack appropriate techniques to teach English comprehension effectively, more workshops should be done to empower them in order to become competent teachers. Teachers need more training on active approaches in order to change their comprehension instruction and to select texts that are relevant to learners’ life situations or experiences, in order for them to relate with the text and thus would cause them to read with understanding.

- Description: The study examines strategies used by teachers to promote reading: A Case of English First Additional Language Learners. The study was located within the constructivism paradigm of reading and used a qualitative research approach that incorporated a case study research design in the collection, analysis and interpretation of the data. The data instruments used were interviews and observations. Data were analyzed using non-statistical procedures. The findings of the study revealed that reading problems are still eminent in Grade Four. It was found that the resources in schools inhibits the progress to promote reading. The educational system is underdeveloped and under resourced with respect to reading materials, and schools are in a bad state due to obsolete facilities. Inadequate infrastructure is also another challenge since most of the participants reported that classes are overcrowded; thus, limiting the space to interact with learners. It was found that primary schools have no libraries; as a result, it was difficult for the teachers to instill the culture of reading. Some participants revealed that technology can be useful to encourage reading, however, their schools have no computer centers and most teachers do not know how to use computers. It emerged from the findings that parents fail to involve themselves in their children’s education. In addition, it was found that poor socio-economic backgrounds affect many homes, and this has a negative impact on schools. Most South African parents are found to be unable to support their children at all. There are also challenges interconnected with the English First Additional Language learners, the eccentricities of the English language, the teacher training and continuing professional development of teachers, as it emerged from the findings of this study that most teachers do not understand the reading strategies, skills of teaching reading and learners lack vocabulary, hence their resistance to reading. A comprehensive model of strategies to improve reading in primary schools was developed by the researcher based on the findings of the study and an extensive literature review.

- Description: Information Communication Technology (ICT) is becoming popular especially within a university campus setting not only as a learning tool but also for the purpose of communication. Internationally there is an acknowledgement of the popularity of ICT in delivering mental health services. This study is built on that premise which indicates that ICT could serve as a viable tool for counselling interventions within a university setting. However, limited research has been done in this area and conflicting results have been reported especially related to gender. This study therefore aimed at exploring the intentions and attitudes of male and female students towards using ICT for counselling at a South African university. A quantitative research approach was employed to collect and analyze data. Data was collected amongst students using self-administered questionnaires with a sample of 266 (N = 266) respondents. Descriptive and inferential statistics were employed. The main findings of the study indicate that students have an intention to seek psychological help through the use of ICT counselling, which consequently positively influenced attitudes towards the utilization of ICT counselling. Results further indicate that gender and age differences amongst university students is significantly related to the intention to use ICT counselling. The information generated from this study has contributed to the limited body of literature on ICT in counselling psychology, more specifically in a university setting in South Africa. Overall, it encourages critical reflection on modern psychological practice to meet student’s needs.

- Description: This study is a qualitative study focusing on the sustainability challenges affecting the performance of community radio stations in Eastern Cape using Forte FM and Vukani FM as case studies. For the purpose of this study, in-depth interviews and focus group interviews were used to collect data and the researcher had in-depth interviews with the station managers of both radio stations. Another interview was conducted with the programme manager of the Media Development and Diversity Agency (MDDA). In addition, this study conducted one focus group interview with purposively selected participants for each community radio station to get their views on the functioning and sustainability challenges facing each of the radio station and how they see them helping their communities. The findings of the study revealed that the major sustainability challenges faced by the stations are finances and lack of resources. The lack of resources is a major problem as it reflects a lack of political will and policies that have failed to recognize the importance of communication as a social process that can help to bring change and development (Fraser & Estrada, 2003:3). As revealed by the findings of this study, the most serious challenge that both stations face is financial sustainability as they had said they struggle to function because they do not have money to pay their staff, and to pay the National Community Radio Forum (NCRF) in order to be kept on air and to deliver their content to the targeted audiences. This study also found out that the stations are not able to train their reporters while they are not getting a regular assistance from the Minister of Communications. The radio stations noted that the Department of Communications used to assist them some years ago but now support only comes from the MDDA. On the other hand, the study also revealed that the MDDA do assist the community radio stations by providing them with necessary broadcasting and transmission equipment and facilities to make sure that they stay on air. This study therefore, concludes that despite the several sustainability challenges faced by these community radio stations, they are still able to contribute to the development of their communities

- Description: Eight series of thirty (30) novel heteroleptic ruthenium(II) complexes were designed, synthesized and spectroscopically characterized, with the following general molecular formulae as [Ru(bdmpmar)(H2dcbpy)(NCS)]+, [Ru(bdmpmar)(vpdiinp)(H2dcbpy)]2,+, [Ru(bdmpmar)(vpbpp)(H2dcbpy)]2+,[Ru(H2dcbpy)2(N^)(NCS)]+, [Ru(H2dcbpy)2(N^)2]2+, [Ru(H2dcbpy)(N^)2(NCS)2], [Ru(H2dcbpy)(N^)(NCS)3]– and [Ru(vptpy)(H2dcbpy)(N^^^)]2+ where bdmpmar is a tridentate ligand of N,N-bis(3, 5-dimethylpyrazol-1-yl-methyl) aromatic organic compound (such aromatic organic compounds(Ar) are anthranilic acid, 4-methoxy-2-nitroaniline, aniline, toluidine, cyclohexylamine and anisidine), vpdiinp represents a monodentate ligand of 11-(4-vinylphenyl)diindeno[1,2-b:2’,1’-e]pyridine, vpbpp represents a monodentate ligand of 4-(4-vinylphenyl)-2.6-bis(phenyl)pyridine and vptpy represents a tridentate ligand of 4’-(4-vinyl)-2,2’:6’,2’’-terpyridine. Meanwhile, N^ represents any of the monodentate ligands of either vpdiinp or vpbpp and (N^^^) represents any of the monodentate ligands either of vpdiinp or vpbpp or NCS as disclosed in series VIII. The complexes were characterized by conductivity measurement, solubility, melting point, UV-Vis, PL, FTIR (ATR), NMR, Cyclic and square wave voltammetry. Nine chelating ligands, comprising of six (6) tripodal chelating ligands, two (2) vinyl monodentate ligands and one (1) vinyl tridentate ligand, were used for the synthesis of ruthenium(II) complexes ATR-FTIR spectra of all the ruthenium(II) complexes measured as solid samples, exhibited fine resolution IR bands in region between 3473-3438 cm-1 of carboxylic group in H2dcbpy. The bands in the range 3040-2950 cm-1 were ascribed to C-H bond stretching for the CH3 groups. The coordination of NCS group in the sphere of ruthenium(II) complexes related to series I, IV, VI VII and one compound of series VIII was investigated by ATR-FTIR spectroscopy. Bands in the range of 2116-2106 cm-1 and 777-770 cm-1 are ascribed to the respective N=C and the C=S bond stretching vibration which confirms the N-coordination of the SCN group. For all the complexes, the stretching vibration of Ru-N bonding was between 466 and 411 cm-1 due to coordination of the nitrogen atoms of the ligands to ruthenium central metal atom. The introduction of the two vinyl monodentate ligands (vpdiinp and vpbpp) in the coordination sphere of [Ru(bdmpmar)(vpdiinp)(H2dcbpy)]2+, [Ru(bdmpmar) (vpbpp)(H2dcbpy)]2+, [Ru(H2dcbpy)2(N^)(NCS)]+, [Ru(H2dcbpy)2(N^)2]2+, [Ru(H2dcbpy)(N^)2(NCS)2], [Ru(H2dcbpy)(N^)(NCS)3]– and [Ru(vptpy)(H2dcbpy)(N^^^)]2+ respectively, all related to series II, III, IV, V, VI, VII and two compounds of series VIII ruthenium(II) complexes, has been studied using the 1H and 13C NMR spectroscopy techniques. The 1H NMR spectra of series II-VII and the two compounds of series VIII of the ruthenium(II) complexes show multiplets in the aromatic region above 6 ppm due to the presence of either vpdiinp or vpbpp ligand, situated in different magnetic environment. However, no splitting pattern was observed in series I and part of VIII complexes possibly due to the absence vinyl monodentate subunits (vpdiinp and vpbpp) in series I and one of compound in series VIII ruthenium(II) complexes show no signals of complex splitting patterns. Carbon-13 NMR spectra data of series I to VIII ruthenium(II) complexes show most resonance signals range in the aromatic region of (δ 116.54-199.63ppm) corresponding to the molecular formulation of ruthenium(II) complexes incorporating 4,4-dicarboxy-2,2’-bipyridine, bdmpmar, vptpy, vpdiinp or vpbpp and NCS ligands respectively, depending on the intrinsic ligand variations. Carbon-13 NMR spectra data of series I, IV, VI VII and one compound in VIII show resonance peaks within the range 130-135 ppm are ascribed to NCS ligand confirming the presence of N-coordinated thiocyanate. Cyclic voltammograms of series I-IV and VI-VIII complexes display ruthenium-based oxidative peaks and the pyridines ligand-based reductive peaks. The redox behavior of complexes 4-12, 14-16, 18-20, 24-26 and 30 is dominated by the Ru(II)/R(III) redox couple in region (E1/2 between 0.53 and 1.18) and the pyridines ligand-based redox couples in the region between (E1/2 between −0.25 and −1.45). The photophysical property studies of the Ru(II) complexes are determined through the acquisitions of the absorption spectra, which tends to have profound effect on the short circuit current of DSSC. The absorption maxima were tuned by the introduction and variation of six (6) tripodal chelating ligands, two (2) vinyl monodentate ligands and one (1) vinyl tridentate ligand. From the studies, the results show that series IV, V, VI, VII and VIII complexes of molecular formula [Ru(H2dcbpy)2(N^)(NCS)]2+, [Ru(H2dcbpy)2(N^)2]2+, [Ru(H2dcbpy)(N^)2(NCS)2]2+, [Ru(H2dcbpy)(N^)(NCS)3]2+ and [Ru(vptpy)(H2dcbpy)(N^^^)]2+ respectively, have higher and multiple local absorption maxima near-IR region than the complexes of series I, II and III of molecular [Ru(bdmpmar)(H2dcbpy)(NCS)]2,+, [Ru(bdmpmar)(vpdiinp)(H2dcbpy)]2,+, [Ru(bdmpmar)(vpbpp)(H2dcbpy)]2,+respectively.

- Description: Malaria is a deadly disease and its drug resistance has been reported to be a challenge globally. The death toll caused by malaria has increased rapidly in different regions of the world. Quinoline scaffold molecules are combined with other classes of antimalarials to tackle drug resistance. The combination of quinoline scaffolds with other antimalarial compounds and metals-based drugs have been reported to be a potential approach to overcome drug resistance common in the currently used antimalarials. 4-Aminoquinoline was hybridized with selected organic molecules and metal-based compounds to form a class of hybrid compounds containing either an amide bond or ester bond as a linker between the parent molecules. 4-Aminoquinoline derivatives are known compounds and they were prepared via known synthetic routes and characterized. The hybrid compounds were characterized and the FTIR results confirmed the successful linkage of 4-aminoquinoline derivatives to selected organic scaffolds to form hybrid compounds. NMR results confirmed the successful formation of hybrid compounds. MS showed signals of the hybrid molecules confirming the successful isolation of the hybrid compounds. In vitro antiplasmodial assay was performed against asexual parasite and chloroquine was used as a reference drug. The percentage inhibition effects of the hybrid compounds were in a range of 96-102% at 5 µM and 36-96% at 1 µM suggesting that the percentage inhibition effect of the hybrid compounds was influenced by the drug concentration. Hybridization of either 4-aminosalicylic scaffold or ferrocene butanoic acid with 4- aminoquinoline derivatives is a potential synthetic route that can result in potent antimalarials. However, more research is needed to fully understand the structure-activity relationship of these hybrid compounds.

- Description: The depletion of fossil fuels and the increasing energy demand for energy has led to the search for better and improved technologies with special focus renewable energy, especially solar cells. The first generation solar cells based on silicon are expensive, hence dye sensitized solar cells come in as a better alternative as these solar cells are environmental friendly, they have moderately good conversion efficiency and they are relatively cheap to produce. Dithiocarbamate ligands have been widely used in many research fields, as these are versatile ligands. Coordination of dithiocarbamates with metals such as ruthenium has produced high conversion efficiency and have the ability to extend the MLCT absorptions, and this can further extend their wavelength. In this study five dithiocarbamate sodium salt ligands were prepared and were coded as FL1= Aniline, FL2= p- toluidine, FL3= p- anisidine, FL4=dibenzyl, FL5=diphenyl. These ligands were used to synthesize Ru(II) metal complexes which were formulated as [Ru(FLx)(dcbpy)(NCS)] and [Ru(FLx)2(dcbpy)] where FLx is the dithiocarbamate ligand and dcbpy is 2,2-bipyridine-4,4’-dicarboxylic acid and the complexes were coded as FCx. The synthesized compounds were characterized using techniques such as the melting point, molar conductivity, FT-IR and NMR spectroscopy. For spectroelectrochemical studies of the metal complexes, techniques such as UV-Vis and photoluminescence spectroscopy were carried out. Furthermore, redox properties of the complexes were analyzed using cyclic and square wave voltammetry. The FT-IR displayed all the expected peaks of interest both in the dithiocarbamate ligands and in the metal complexes. The electronic spectra confirmed the successful coordination of ligand to the metal centre, the electronic spectra of the complexes also confirmed the six coordinate octahedral geometry of the complexes. The complexes exhibited some photoluminescence properties that are suitable for dye sensitization. The cyclic voltammogram of the complexes displayed more reduction potentials that could be attributed to the π-conjugation in the ligands incorporated during synthesis. The square wave voltammogram of the complexes is in agreement with the results obtained in cyclic voltammetry.

- Description: Attention Deficit Hyperactivity Disorder (ADHD) affects between 5 – 7 percent of children in the United States and Europe, making it one of the most common child psychiatric diagnoses. ADHD currently affects approximately 3 – 5 percent of school-going children and adolescents in South Africa. Schools create multiple challenges for learners with ADHD who show classic symptoms of inattention, hyperactivity and impulsivity. These symptoms produce impairment across cognitive, behavioural and interpersonal domains of function. Symptoms frequently manifest in a school setting, thus teachers play a central role in reporting symptoms, advising parents to seek professional assessment and assisting children with ADHD to achieve academically and socially. In line with the Education White Paper 6 of 2001, teachers should not only support learners with ADHD, but need to help these learners to understand and accept themselves as learners. The Literature focus on teachers’ knowledge of the characteristic symptoms displayed by learners with ADHD; teachers’ role in identifying and referring learners with ADHD; challenges faced by teachers when teaching learners with ADHD as well as teaching strategies and classroom accommodations teachers employ to effectively support learners with ADHD. The research was undertaken as a qualitative case study with an interpretivist underpinning. Data was collected making use of open-ended questionnaires, semi structured interviews and an informal observation. Purposive sampling was used to identify 6 teachers from previously disadvantaged high schools, teaching either Mathematics or a Language. The findings of the study indicated that teachers in mainstream high schools do not possess adequate knowledge to identify and refer learners with ADHD. As assumed by the researcher, the teachers’ lack of knowledge leads to unsuitable teaching strategies and classroom accommodations. Their biggest challenge to effectively support learners with ADHD was a lack of support and knowledge.

- Description: The acceptability of zero tillage amongst small-scale farmers is a challenge in the Eastern Cape Province as farmers have different strategies on how to manage residue. This situation is due to the limited information available on the benefits of implementing zero tillage, such as improving soil health. The Department of Agriculture and Agrarian Reform have been assisting small-scale farmers by subsidising them with the latest innovations, such as zero tillage. The main essence of these initiatives was to compensate farmers that are previously disadvantaged as a result of the apartheid system prior to 1994. Zero tillage has recently gained more attention as one of the most important farm practices due to its benefits for soil conservation and the elimination of greenhouse gases. The study was conducted at Magadla and Nkawu villages in Matatiele, Eastern Cape. The objective of the survey was to examine the influence of current residue management practices amongst Matatiele farmers in the light of the adoption of zero tillage practices. The data was collected using questionnaires and group discussions. The statistical package SPSS and Microsoft Excel were used to analyse data. The findings showed that the adoption percentages of zero tillage by small-scale farmers was 34 percent and 65 percent in Magadla and Nkawu villages respectively. Amongst the challenges that non-adopters faced were shortage of inputs, weak communication channels between farmers and coordinators, residue benefits to livestock and lack of proper monitoring and evaluation. Binary logistic model was adopted and used to analyse 13 independent variables that influence the adoption of mulching in the study area.

- Description: The aim of this research study is to explore the subjective views and experiences of black men who were perpetrators of domestic violence and have gone through a rehabilitation programme as a result. This paper also explores the connection between masculinity and domestic violence, and how perpetrators make sense of the concept of domestic violence and abuse. The reason underlying the study is to contribute to the fight against domestic violence, perpetrated by males, by understanding the root cause of the problem. This topic emerged due to the lack of sufficient academic papers on men as perpetrators of domestic violence, therefore the intention is to progressively close the gap and contribute to the already existing knowledge on the issue of domestic violence. The study comprised of four research participants gathered from different NGOs and thus different backgrounds. The sample comprised of two Black males and two Coloured males. It is worth noting that for the purpose of this study, black men refers to all men of colour. Thus, both African males and Coloured males fall under the same umbrella of Black men. An Interpretive Phenomenological Analysis from the Qualitative paradigm was used to analyse the data received from semi-structured interviews. The themes that arouse from the study were 1) Learning gender roles through observation; 2) Masculinity learned through teachings; 3) Misinterpreting African values; 4) Intoxication makes it easier to hit a woman; 5) Difficulty dealing with deep emotions; 6) Control and ownership in the relationship; 7) Gender roles forced by society; 8) Lack of consequences; and 9) Masculinity matures. The findings of the study is that masculinity is connected to men perpetrating domestic violence through misinterpreting African values that are taught by elders. Even though masculinity is taught to boys at a tender age, it was discovered that for some of the participants, masculinity is not stagnant but rather constantly changing as the individual grows in personality and life experiences, and thus their values change. As a result of this discovery, masculinity is also individualistic. These findings could assist in future research. Perhaps a much larger research focusing on evaluating, and later, developing rehabilitation programmes that speak to the individual experiences and beliefs of different South African males in order to accommodate the diverse cultures, and thus the beliefs that South Africa shares amongst its people.

- Description: Let G be the cyclic group Zpn _ Zqm _ Zr where p; q; r are distinct primes and n;m 2 Z+. Using the criss-cut method by Murali and Makamba, we determine in general the number of distinct fuzzy subgroups of G. This is achieved by using the maximal chains of subgroups of the respective groups, and the equivalence relation given in their research papers. For cases of m, the number of fuzzy subgroups is _rst given, from which the general pattern for G is achieved. Murali and Makamba discussed the number of fuzzy subgroups of Zpn _ Zqm using the cross-cut method. A brief revisit of the group Zpn _Zqm is done using the criss-cut method. The formulae for _nding the number of distinct fuzzy subgroups in each of the cases is given and proofs provided. Furthermore, we classify the fuzzy subgroups of the group Zp1_Zp2__ _ __Zpn for p1; p2; _ _ _ ; pn distinct primes and n 2 Z+ using the criss-cut method. An algorithm for counting the distinct fuzzy subgroups of this group is developed.

- Description: The Eastern Cape Province have high numbers of livestock but high poverty rates remain very high. This study therefore, aimed to determine the contribution of smallscale livestock farming to rural household income in the King William’s Town area in five rural areas. Literature shows that the livestock sector contributes 40 percent of global value of agricultural output and supports the livelihoods and food security of almost a billion people. The data collected for this research were both quantitative and qualitative and cross-section design was employed for the research. The study used both simple random sampling and availability sampling to select 125 sample households, 25 respondents from each village. Descriptive statistics was used in the analysis of demographic and socio economic characteristics of households where graphs and tables were used to present the relevant information. Probit regression model was used to determine factors influencing the decision to practice livestock production and marginal analysis was calculated to determine the effect of changes of individual variables. For the assessment of the contribution of small-scale livestock farming to household income Propensity Score Matching (PSM) model was fitted. Results show that the highest percentage of livestock kept by households in 5 villages is 56 percent for poultry and the lowest percentage is 2 percent for pig. The main source of income for many households in the study area was the income from pensions and grants but livestock farming is also contributing to household’s income through income generated from sales of livestock for customary events such as traditional rituals and celebrations, lobola, funerals and weddings. Many of the households have secondary education and the reason might simply be that in olden days’ parents had no money to pay school fees of their children and that limited children to go further with their studies. The results of the marginal effects estimates for the probit model suggest that changes in the number of livestock sold would have important effects on household incomes. There are various challenges that livestock producers are facing in their production and the major challenge that households are facing is parasites and diseases as they decrease number of livestock kept by households. Parasites and diseases suck blood, causing the animals to become weak and sometimes resulting in high mortality rate. It is recommended that livestock producers should be made aware of the impacts of various challenges that affect livestock farming through awareness creation programmes and suggest solutions to overcome those challenges.

- Description: Small-scale fisheries are known to provide food and income to millions of people around the world, but their role and existence is often ignored in development planning. The growing human demand for animal protein has become one of the foremost world challenges for which aquatic organisms have a significant role to play. In South Africa, small-scale fisheries have been recognized since the end of Apartheid, but the extent of the contribution of the sector to rural livelihoods and food security is not well understood. Using data drawn from a sample of 80 fishers in the coastal community of Hamburg, Eastern Cape, this dissertation presents an assessment of the contribution of small-scale fisheries to rural livelihoods, income and food security. The primary data were collected from the fishers using a structured questionnaire and non-probability sampling. The data were analysed with the assistance of descriptive techniques and a few simply statistical tests. The results of the study indicate that fishers in Hamburg catch a wide range of fish, which include wild kob, octopus, spotted grunter, white/black mussel cracker and white steenbras. Fishers in the study area are not solely dependent on small-scale fisheries for their livelihoods, income and food security, but generally supplement their welfare payments with fishing in order to sustain their livelihoods. About 78percent of the surveyed fishers depend on government grants, including old age grants, child support grants and social care grant. In terms of employment, 15percent of the surveyed fishers are casually employed, while 6percent are formally employed on a contract basis. Although they are not only dependent on fishing, nevertheless fishing is an important source of livelihood, income and food security. About 37percent of the fishers harvest marine resources for home consumption, while 7percent harvest solely for income, and 56percent harvest for both home consumption and income. Income generated from fisheries is approximately R935 per month and is used to buy food, electricity, fishing equipment and other household needs. The findings from this research underline the need for interventions such as coordinated institutions, improved infrastructure, improved monitoring and enforcement systems, as well as improved access to permit/fishing rights for sustainable use of marine resources.

- Description: This study attempts to ascertain the economic impact of the process of homeland consolidation in four communities that became part of the Ciskei. It describes the process of homeland consolidation at Lloyd, Bergplaas, Balfour and Qanda, and seeks to understand the effects of homeland consolidation on the level of economic activity in these areas. ‘Homeland consolidation’ was the official term used to describe the policy developed by the central government of South Africa in the 1970s to reduce the number of separate, isolated pieces of land making up each of the Bantustans. It was part of the ultimately unsuccessful and suspect process of turning these areas into independent ‘national states’. The Apartheid government bought out selected white farms/properties/land like in Lloyd, Bergplaas, Balfour and Qanda, and consolidated them with the adjacent homeland territory. The result of this process made commercial farmland available to black people. In a very narrow sense, this particular aspect of homeland consolidation was an antecedent of land reform. Because homeland consolidation took place some time ago, discerning the economic effects relied above all on people’s recollections of their past experiences, which could only be quantified in a very limited manner. In other words, the data and analysis were largely although not exclusively qualitative. Household and life history interviews were conducted using semi-structured questionnaires, and then the data was analyzed using content analysis, descriptive statistics, the Chi-square test and the two-proportion z test. Through the process of homeland consolidation and forced removals, people ended up losing productive land and livestock because they were forced to sell their livestock at a loss and they had no land where they were moved to. People were stripped of their livelihoods, in addition to losing a place that they called home and the loss of employment. This study also looked at the changes in farming before and during the apartheid era, during the time when the Ciskeian government was in power and after 1994 till now. And also looked at the broader perspective of what actually happened in the four sites from the life history interviews.

- Description: Power Electronics (PE) forms the major part of the syllabus for the Industrial Electronics (INDE) course of the National Diploma (ND) programme in Electrical Engineering. This study investigated the effect of Guided Enquiry-Based Learning (GEBL), an Active Learning (AL) approach on Electrical Engineering students’ recall ability, conceptual understanding of PE, problem solving skills and critical thinking ability. The study was carried out at one of the campuses of a selected university in South Africa’s Eastern Cape Province in an attempt to check if GEBL would improve student performances in the above focused areas. The expected population for this research in 2017 was 21, similar to the numbers enrolled in 2016. However, in 2017 the enrollment dropped to 14 and this posed a limitation. Since cancelling the study due to the drop in enrollment would have caused the loss of a research report on PE students, it was decided to continue with it. This was especially so, since no other report on PE within South Africa could be located. The instruments were developed using inputs from subject experts to ensure content validity. Cronbach’s Alpha was used to test the reliability of the instrument. A pilot study was conducted during the previous year with the 2016 PE students and deficiencies in the instruments were rectified. Out of the 14 students in 2017, seven volunteered to be taught using the GEBL approach. All ethical considerations applicable to the study were adhered to. All students from the GEBL group signed the informed consent forms prior to the study. The study adopted a pragmatist paradigm and a mixed method approach. A quasi experimental non-equivalent group post-test only research design was used where both the experimental group and the control group were selected (without random assignment). The post-test only design was selected because of the time constraints with the semester courses. A student-centred GEBL approach was used as an intervention for the experimental group and a teacher-centred traditional approach was used for the control group. Students from both the GEBL and Traditionally Taught Groups (TTGs) were subjected to the same assessments. Quantitative data were collected from two formative assessments and one summative assessment and the qualitative data were collected by interviewing all students from the GEBL group. The collected data were statistically and thematically analysed to determine the extent to which the intervention affected the students’ recall ability, conceptual understanding of PE, problem solving skills and their critical thinking ability. The main conclusions were that when compared to the traditional approach, GEBL was significantly more effective in enhancing recall as well as understanding of PE concepts. However, significant differences were not evident in problem solving and critical thinking. The recommendations are that: students must be encouraged to be more active in the learning process; the shift of strategy from traditional to AL methods such as GEBL must be introduced gradually; and the benefits of GEBL and exposure to it must be popularised in order to develop positive attitudes to GEBL not only among students, but also teaching staff.

- Description: The objective of the study was to determine the effect of feeding graded levels of Moringa oleifera leaf meal powder (MOLP) on growth performance, carcass characteristics, economic analysis, health status, physicochemical, sensory properties, mineral composition and retention values of meat. A total of 1600 Comb-500 day-old unsexed chicks were allotted to 4 dietary treatment groups, with 4 replicate pens of 100 birds each in a completely randomised design. The dietary treatments were basal diets supplemented with different levels of MOLP as follows; Treatment 1/ control: Basal diet with antibiotic Zinc bacitracin and coccidiostatic Maxiban and no MOLP (0MOLP); Treatment 2: Basal diet included 1percent MOLP (1MOLP); Treatment 3: Basal diet included 3.0 percent MOLP (3MOLP); Treatment 4: Basal diet included 5 percent MOLP (5MOLP). Birds fed basal diets plus 5percent MOLP at starter phase achieved the least FCR 1.53 (P < 0.037), whilst consuming significantly less feed ADFI 47.4 g (P < 0.05). For the entire feeding period, birds fed 5 percent MOLP achieved a favourable FCR of 1.80 among all treatment groups (P < 0.001), but achieved the lowest final live weight (1416 g), carcass weights (1044g) (P < 0.05). Birds fed 0 percent MOLP recorded highest final weight, carcass weight (1339) and the best dressing percentages (76.8percent) (P < 0.05). Abdominal fat levels were reduced by elevating MOLP in diets (P < 0.05). Improvements in proportions of giblets, gizzard, liver and intestine were observed with increase in dietary MOLP. Feed costs increased, while gross and net returns and economic efficiency decreased as dietary MOLP increased. Organ indices of spleen, Bursa of Fabricius and liver were significantly increased by 5percent MOLP in the diet (P < 0.05). Macroscopic lesions scores (P < 0.05) were significantly higher in duodenum, jejunum and ileum of birds in the 1MOLP treatment group on d 28 and d 35. Control and 5MOLP groups recorded the least bloody excreta scores among all treatment groups (P < 0.05). Highest total aerobic bacteria (TAB), E. coli, C. perfringens counts and the lowest lactobacillus spp counts were observed in all intestinal segments in birds in the 1MOLP treatment group. Lower E. coli and C. perfringens but higher lactobacillus spp counts were observed in control and 5MOLP groups (P < 0.05) in the duodenum and jejunum. Increasing MOLP levels in diets led to lower pH and pHu in both breast and leg muscles (P < 0.05). pH was consistently lower in leg muscles than in breast cuts in all treatments and a large decline in post-mortem pH was observed in all muscles of birds in control group. A dietary increase in MOLP level led to a significant increase in L* and b* (P < 0.05) negative correlation between pH and L* (r = -0.463) (P < 0.05) and a weak but significant (P < 0.001) correlation (r = 0.176) between pH and drip loss. Herb flavour (P = 0.0029), appearance (P = 0.0156), aroma (P = 0.0011), colour (P = 0.0375), taste (P = 0.0032) and overall acceptability (P = 0.0192) were improved by grilling, microwave cooking and pan-frying in olive oil. These changes were more pronounced in breast muscle, thus following the trend; microwave > pan-frying in olive oil > grilled samples > boiling for best cooked product based on overall acceptability. Grilling and frying heart muscles resulted in the highest Ca (45.9 mg/kg) and Mg (98.9 mg/kg), whereas boiling led to the lowest Ca (41.1 mg/kg) and Mg (91.4 mg/kg) concentration. The highest concentrations of Fe and Zn these minerals were recorded in grilled (32.7 mg/kg) and fried samples (75.2 mg/kg). Zinc and Fe concentration observed in liver and heart muscles were higher than those found in breast and leg muscle. In conclusion, the results confirm the potential of MOLP for use as an alternative to antibiotics in maintaining broiler health, reducing mortalities and improving carcass characteristics and some meat quality traits.

- Description: The Employee Assistance Programme (EAP) is a programme used by organizations to address problems related to drug addiction, stress and family problems, aimed at enhancing both work productivity and promoting high morale among the workers. The employees in the Department of Health (DoH) are faced with many challenges which affect them, personally, and their output at work. The OR Tambo District is currently faced with high levels of absenteeism, stress, low morale amongst health staff members, resulting in most employees resigning from the service. Others die due to ill health caused by high levels of stress and depression. Some employees are being dismissed for unethical behaviour, which include, among other things, alcohol and drug abuse and abuse of state resources, non-performance and absenteeism. Furthermore, due to the shortage of staff which results in a very high workload for the incumbents, some employees experience burnout, stress, depression and exhaustion. The main objective of the study was to assess the effectiveness of the Employee Assistance Programme among OR Tambo health workers in order to improve their work productivity and performance. The study applied a descriptive, quantitative design. The target population were all employees in the Forensic Pathology Laboratory in OR Tambo District and the sample included Managers, FPOs, Supervisors and General Assistants. The questionnaire was used to collect data. The major findings of the study demonstrated that most workers are dissatisfied with their personal growth and development in the organization. Furthermore, the results indicate that respondents are not satisfied with the decision space in their job functions, salary and benefits. The findings of this study demonstrated that most employees of the Department of Health experienced health, emotional and financial problems relating to alcohol and drug abuse, stress and work overload in their workplace. The study shows that the managers referred their employees for cases related to poor performance, absenteeism, alcohol and drug abuse, tiredness, employee and health problems; changes which were noticeable after referral. One of the major conclusions and recommendations that have been drawn in this study is that EAP is a good programme in terms of its contribution to work productivity of employees, however, it needs to be marketed and services should be utilized effectively.

- Description: The Zimbabwe Prison and Correctional Services records show that there are around 300 children incarcerated every year. Most of these children commit crimes such as rape, murder, theft, possession of drugs due to issues like poverty, substance abuse, peer pressure and neglect. A number of these children face many forms of abuse in their homes, including physical, emotional, mental abuse as well as rape. The major aim of the study was to investigate the effectiveness of juvenile delinquents’ rehabilitation programmes at Harare Central Prison. The qualitative methodology was appropriate for this study because it gives in depth information through conducting interviews and focus groups with participants. The sampling procedure involved deliberate choice of an informant due to the qualities the informant possessed. A sample size of thirty-seven participants comprising sixteen juvenile delinquents, four social workers, five prison guards, five probation officers and seven community members, were selected for this study. Their perceptions provided baseline data that helped in gaining a deeper understanding of the juvenile rehabilitation programmes. Despite the findings, gaps remain in the current system, for instance children continue to spend prolonged periods of time in adult prisons while they await repatriation to institutions due to resource constraints, and the rehabilitation programmes have proved to be partially effective, yet at the same time the post rehabilitation programmes are not being provided to juveniles after their release from prison. Key recommendations include expanding the Pre-trial Diversion Programme to all the provinces as it has yielded results that benefit the child as well introduction of alternatives of institutionalisation.

- Description: Shale gas has become a part of the world’s energy mix. South Africa (SA) is facing huge energy problems and job creation challenges whilst the Karoo region has large amounts of shale gas reserves. It is against this background that the South African government is considering fracking, showing interest by lifting fracking ban and repeatedly calling it a game changer. This generated debates among environmentalists, farmer groups, capitalists, politicians, researchers and community groups, as they voiced their views regarding fracking. The debates influenced the study to focus on public participation regarding the Karoo fracking initiative, with particular emphasis on the marginalised persons. The aim was to examine the effectiveness of public participation in the environmental politics of fracking in the Great Karoo region in Eastern Cape Province. The study adopted a qualitative case study approach through document analysis, questionnaires given to the interested and affected parties, relevant government department, local municipality and non-governmental organisations as well as focus group discussions with 35 participants from marginalised groupings. It was grounded on the Integrated Environmental Management (IEM) paradigm using the outcomes-based framework in the thematic analysis of the collected data. The results showed little evidence of social learning among the marginalised persons when the collected data was benchmarked against the chosen pillars of the IEM paradigm within the outcomes-based approach. These results convey that effective and developmental public participation should be empowering, informing and educating rather than merely serving documentary purposes.
