- Description: This classroom-based action research dissertation examined visualisation strategies used by pre-service Intermediate Phase PGCE education students to solve mathematical word-problems. The setting was an Eastern Cape university. Previous literature indicated a positive correlation between the use of visual scaffolds and success in solving word problems. However, a gap was found insofar as little research had been published on the application of visualisation to word-problems by student teachers in South Africa. This thesis advances our understanding of the role visualisation may play in assisting student teachers to solve word-problems. The theoretic framework was informed by Bruner’s theory of learning. The research was grounded in the hermeneutic tradition. An interpretivist research paradigm was expedited by using an inductive, naturalistic perspective and relativist ontology. Thirtyeight student-teachers participated in the study. Parallel and convergent qualitative and quantitative data gathering instruments were used, thereby facilitating triangulation and examination for microgenesis. It was found that vestiges of past teaching practices initially limited the participants’ knowledge to a deeply-flawed, banking model of routines and an instrumental perception of mathematics. Disruptive calls for social justice impeded progress. Albeit visualisation strategies liberated understanding, many foundational concepts and skills had to be reconstructed. The confluence of time and rehearsal culminated in some measure of expertise. Sustained effort enabled new knowledge to be compressed and consigned to long-term memory. Salient visual representations assisted participants to conceptualise relational mathematical metaconcepts and reduced the cognitive demands imposed by word-problems but that achievement was a hard-won prize.

- Description: Polyamidoamine drug conjugates were prepared from analogues of ferrocene and platinum. Standard reaction procedures were followed in the synthesis of platinum and ferrocene analogues. Michael addition reaction of amines to the activated double bonds of methylenebisacrylamide was applied for preparation of the water soluble polyamidoamine carriers onto which drug analogues were attached. The drug release studies of the conjugates were evaluated at different pH environments. The results obtained from drug release studies showed that rate of drug release was variable depending on the conjugate and pH environment. Mathematical drug release models by Korsmeyer-Peppas were used to determine the drug release characteristics of the ferrocene and platinum based drugs from polyamidoamine drug conjugates. Cytotoxicity potential of the analogues and polyamidoamine drug conjugates was tested on selected cell lines. Cisplatin was used as the standard for comparison of the IC50 values obtained for the compounds tested for cytotoxicity activity. The results from six polymer drug conjugates tested for cytotoxicity activity showed that conjugation of analogues to polyamidoamine carrier enhanced the activity of the analogues in some of the polyamidoamine drug conjugates. Various techniques such as Fourier Transform Infrared (FTIR) spectroscopy, Proton Nuclear Magnetic Resonance spectroscopy (1H NMR), Scanning Electron Microscopy (SEM), transmission electron microscopy (TEM), Transmission Electron Microscopy (TEM) and Energy Dispersive X-ray (EDX) spectroscopy were employed for the characterization of the ferrocene and platinum analogues, polyamidoamine carriers and drug conjugates.

- Description: Inadequate quantity is a major impediment to the industrial application of peroxidase and other industrial enzymes. Consequently, efforts are geared towards increasing peroxidase production by searching for new microbes with enhanced production capacity. In this study, three novel ligninolytic bacteria: Raoultella ornithinolytica OKOH-1 (KX640917), Ensifer adhaerens NWODO-2 (KX640918) and Bacillus sp. FALADE-1 (KX640922) were optimized for peroxidase production and their peroxidases characterized using molecular and biochemical approaches. Molecular analysis confirmed the presence of peroxidase genes in the three bacteria. BLAST result and phylogenetic analysis of the deduced amino acid sequences suggested that Raoultella ornithinolytica OKOH-1 peroxidase (RaoPrx) belongs to a DyP-type peroxidase family while peroxidases from Ensifer adhaerens NWODO-2 and Bacillus sp. FALADE-1 are catalase-peroxidases. The peroxidase genes are available in the GenBank with MF370527, MF374336 and MF407314 as respective accession numbers. Upon optimization, Raoultella ornithinolytica OKOH-1 exhibited the highest peroxidase production at pH 5, 35 oC and 150 rpm. Biochemical characterization showed that RaoPrx had a wide substrate specificity as it was able to oxidize all the tested substrates in this study (ABTS, veratryl alcohol, guaiacol and pyrogallol), except 2, 6-Dimethoxyphenol. However, highest activity by the enzyme was recorded with pyrogallol as substrate. The enzyme had an optimum activity at pH 6 and 50 oC and was very stable at high temperatures (50 oC – 70 oC). Its pH stability was over a pH range of 5.0 – 7.0. Moreover, RaoPrx activity was significantly enhanced by Ag+, Cu2+, Zn2+and Fe2+ while Ca2+, Mg2+, Ba2+, Al3+, Co2+, NaN3 and EDTA inhibited the activity of the enzyme. Nevertheless, RaoPrx exhibited a remarkable dye-decolourizing activity on congo red and melanin, indicating the biotechnological potential of the enzyme in dye decolourization and development of cosmetic agent. Generally, the results from this study suggest that ligninolytic bacteria hold a great potential for enhanced peroxidase production that could meet the increasing industrial demand.

- Description: Low maize yields in the midst of abundant arable land, favourable climatic conditions, input and financial support programs, plagues smallholder maize farming in Eastern Cape Province. These scenarios have led the province to be a net importer of maize. In essence, low production may signify a mis-match between maize varieties being promoted amongst smallholder farmers and their farming system. Thus, the main objective of the study was to investigate the productivity and profitability of different maize varieties and cropping system under smallholder agriculture in selected villages of the Eastern Cape Province of South Africa as well as, the implications posed on the household food security. The study sought to assess: (i) the productivity of different maize varieties and cropping systems, (ii) the effect of GM maize adoption on food security among smallholder farmers, (iii) the profitability of GM, conventional hybrids and OPV maize varieties produced by farmers under different agro-ecological conditions and (iv) the impact of different maize varieties and cropping systems on food security in the smallholder agriculture. A cross sectional quantitative-based survey study was carried out to obtain information from a total of 650 small holder farmers. The study was conducted in three local municipalities in Oliver Reginald (OR) Tambo District Municipality of the Eastern Cape Province of South Africa. Descriptive statistics, partial factor productivity, gross margin analysis, household food insecurity access score (HFIAS), ordinal logistic and linear regression were the analytical techniques used in establishing correlations among variables. Results obtained from the survey indicated that under mono-cropping system, Genetically Modified (GM) maize variety was highly productive with an average yield of 1.9 t/ha whilst, improved OPV maize variety was productive (with an average yield of 1.6 t/ha) under mixed cropping system. Furthermore, GM maize (GM = -R418.10), and landrace (GM = -R1 140.29) maize varieties had negative gross margins whilst, conventional hybrids (GM = R5 181.21) and improved OPV (GM = R1 457.41) were profitable. There was a significant and negative correlation between use of GM maize variety and reduction of household food insecurity. GM maize varieties, improved OPV, white maize, white as well as yellow GM maize varieties had a significant impact in reducing household food insecurity; whilst using more than one variety of maize (landraces and GMO) positively influenced household food insecurity. In light of these research findings, it is recommended that, there is need to address household food security by growing improved OPVs under a mixed cropping system and GM maize under monocropping system.

- Description: This thesis investigated how school governance promoted healthy and safe school environments and focussed on elements that make the school environment unhealthy and unsafe. These elements were spatial density, sanitation, ventilation, visibility, the acoustic element of the school environment, the aesthetic element and the psychosocial school environment. These are very important elements, and the neglect thereof could lead to ill health. The study excluded elements such as violence and substance use, as well as HIV/ AIDS. The research was conducted at six schools in the Butterworth and East London Educational Districts, as well as the district office in each of these two educational districts of the Eastern Cape. The design was a case study, and a qualitative methodology was used. The sample consisted of members from the school governing bodies, that is, the principal, one other member of the school governing body and a member of the school management team, as well as one official from each educational district, totalling twenty participants. A non-probability, purposive sampling method was used. The instrument was semi-structured interviews and document analyses. The researcher also made use of photographic evidence. Findings indicated that although support services were in place, promoting a healthy and safe school environment was a challenge at all of the schools. Various contributing factors such as the lack of support from the Department of Basic Education (DBE) for schools and district officials, non – implementation of policies, lack of infrastructure, lack of human and other resources, lack of security personnel and vandalism, prohibited the promotion of healthy and safe school environments. It is recommended that the DBE pays urgent attention to these elements that make the school environment unhealthy and unsafe; that the DBE fills the gap that exists between the national, provincial and district offices that hamper the flow of infrastructure and the supply of human and other resources. There is also a need for workshops on policy writing and implementation thereof. A workshop focussing on these elements that make the school environment unhealthy and unsafe would also be beneficial.

- Description: This study sought provision of psychosocial support to vulnerable learners by school based peer-led groups in secondary schools. Using the Ecological Systems Theory and the Psychosocial Support Interactive Process Model, the study specifically sought how vulnerable learners were identified, how participants understood vulnerability and psychosocial support, how peer led groups were selected and the strategies used to provide psychosocial support by peer led groups. The study also sought the support and monitoring strategies used by different stakeholders including the department of education inorder to assit the peer led groups in their endevour to provide psychosocial support to vulnerable learners. The study employed qualitative research methods using interviews, focus groups and document analysis. Purposive sampling was used to select a District Education Officer, four principals, four group members and all of whom took part in interviews, then twenty four peer group members who participated in focus group discussions. The study found out that various methods were used to identify vulnerable learners, but these were inadequate due to limited professional support to the peer-led groups. The strategies employed to assist vulnerable learners included the buddy system, scripture unions, boys and girls education movements and home visits. However there were also challenges of shortage of human and material resources such as counselling rooms, transport. Also none cooperation of parents still hampers psychosocial support by peer led groups. Therefore, the study concludes that there are still a lot of vulnerable learners who are not reached by peer-led groups because of the above mentioned challenges. In this light the study proposed a framework for providing psychosocial support. The study therefore, recommends that the psychosocial programme be part of the large school curriculum which has a specific budget to sustain all the identification, support and monitoring needs of the vulnerable learners and to ensure the psychosocial support strategies are successful.

- Description: The motivation for this study originated from the problem of children who are victims of rape in the victim support centers. The researcher became aware that most of the children needs more support services for counseling and after care services. The goal of the research was to explore the psychosocial challenges faced by children who are victims of Rape in the victim support Centre. The aim of the study was to determine the psychosocial effects (effects. challenges, support services they receive from professionals) as victims of rape in a victim support center. It was a case study of KwaNobuhle Area, Eastern Cape. The purpose was to identify gaps as there are minimal services rendered to children as rape victims in the victim support Centre. In order to meet the objectives of the study, interviews were conducted to 20 victims of rape (both boys and girls) as well as 6 different professionals working with rape cases from the arrival of the child from the opening until the finalization of the case. Data were analyzed according to the qualitative data - analysis procedures. The researcher utilized the phenomenological research design. The research domain where the interviews took place was at the KwaNobuhle Area under the Department of Social Development jurisdiction. In this study, 20 Xhosa speaking children of different ages, gender, educational standards, and socio-economic backgrounds as well as those who suffered different types of rape, as defined by the Sexual Related Matters Act 32 of 2007; they were all interviewed through the use of a semi-structured interview schedule. The participants were purposively selected as they were all at the victim support center. It has been found that some services are not provided within and are other professionals lack knowledge on how to work effectively with children as victims of rape To add on, the theoretical framework that was used in this study is the victim empowerment theory. This was used as a way of empowering the children who are victims of rape in the Victim Support Centres. The study found out that children who are victims of rape in the Victim Support Centres face psychosocial challenges for instance emotional, educational and behavioural challenges. Furthermore, the study also found out that there are few pschologists in the Victim Support Centres. Therefore, the study recommend that more psychologists should be employed at the Department of health and be placed in Victim Support Centres. More, so, there should be constant supervision and guidance on the care givers within the institution on how to effectively deal with the children who are victims of rape in VSC to avoid psychosocial challenges.

- Description: The current task environment in the South African public hospitals has reconfirmed the importance of researching on the psychological environment and its influence on individual employee performance. The motivation of this study is to examine the relationship between psychological capital and psychological empowerment on the one hand and organisational citizenship behaviour on the other hand among nurses within selected public hospitals in the Eastern Cape Province of South Africa. This contributes to the theoretical conceptual knowledge on how performance can be enhanced through the appropriate provision of psychological resources in the workplace and the promotion of competence, efficiency and sustainability of organisations. Survey questionnaires were used to collect data. Inferential analysis from SPSS was carried out to understand the antecedents and consequences of organisation citizenship behaviour. An overall model of the study was also identified through AMOS using structural equation modeling. Findings from the selected South African public hospitals indicate that there is a significant positive relationship between psychological capital and psychological empowerment on the one hand and organisational citizenship behaviour on the other hand among nurses within the selected public hospitals. The results validate certain aspects of the Conservative frame work and the Job Demands Resources Model. The study recommends that hospital managers and supervisors should determine the social networks in their hospitals as a strategy to promote performance and organisational citizenship behaviour. Individual employees who are located at the fringes of the network must be recognised and empowered. This allows for the comparison evaluation of both individual and organisational characteristics on organisational citizenship behaviour and the promotion of slack resources which are important in maintaining a steady organisational performance which further widens organisational capacity.

- Description: The current task environment in the South African public hospitals has reconfirmed the importance of researching on the psychological environment and its influence on individual employee performance. The motivation of this study is to examine the relationship between psychological capital and psychological empowerment on the one hand and organisational citizenship behaviour on the other hand among nurses within selected public hospitals in the Eastern Cape Province of South Africa. This contributes to the theoretical conceptual knowledge on how performance can be enhanced through the appropriate provision of psychological resources in the workplace and the promotion of competence, efficiency and sustainability of organisations. Survey questionnaires were used to collect data. Inferential analysis from SPSS was carried out to understand the antecedents and consequences of organisation citizenship behaviour. An overall model of the study was also identified through AMOS using structural equation modeling. Findings from the selected South African public hospitals indicate that there is a significant positive relationship between psychological capital and psychological empowerment on the one hand and organisational citizenship behaviour on the other hand among nurses within the selected public hospitals. The results validate certain aspects of the Conservative frame work and the Job Demands Resources Model. The study recommends that hospital managers and supervisors should determine the social networks in their hospitals as a strategy to promote performance and organisational citizenship behaviour. Individual employees who are located at the fringes of the network must be recognised and empowered. This allows for the comparison evaluation of both individual and organisational characteristics on organisational citizenship behaviour and the promotion of slack resources which are important in maintaining a steady organisational performance which further widens organisational capacity.

- Description: Parents/ guardians are facing major problems in South Africa as their children are involved in substance abuse. Both genders are involved in substance abuse meaning therefore that guardians are facing huge challenges especially now that the girls are also involved in substance abuse. This research explored the psycho social challenges faced by guardians whose children are involved with substance abuse at Cofimvaba, in the Eastern Cape Province. The study was premised by four objectives, firstly the study was aimed to examine the challenges that guardians face since their children are involved with substance abuse. Secondly the study was aimed to assess the emotional consequences of the guardians since their children are involved with substance abuse. Thirdly to establish the community perceptions with regard to the involvement of the children with substance abuse. Lastly, to establish the support services the guardians get from professionals. The researchers used qualitative method because it provides a deep understanding of what is under investigation. The design used in the study was exploratory, descriptive and contextual in nature. The study was conducted through qualitative research instruments of in-depth interviews and focus group in collecting the data. The study utilized social learning theory and the systems theory. The population in this study was made up of 20 participants, as well as 5 members forming up a focus group. All the participants were originally from Cofimvaba. The data was analyzed using content thematic analysis. The study revealed the following findings that there are support services given to the guardians at all. The support service is solely meant for the children when reported to be affected by substance abuse. There is high rate of labelling and discrimination to guardians from community members when the child is involved with substance abuse. There is an element of isolation with regard to the guardians whose children are involved with substance abuse. Guardians are sometimes isolating themselves and are scared about the comments that are impose to them because of their children who are involved in substance abuse. All the guardians are not happy and are feeling helpless now that their children are involved in substance abuse. The following are the challenges faced by guardians with regards to their children’s involvement with substance abuse; (i) overspending money because they have to repay all the damages done by their children. When the children are not well, the guardians have to take the children to the doctors. (ii) Behavioural challenges, the guardians are (iii) School performance dropping from the children is affecting the health and welfare of the guardians. Not a single guardian is not ambitious about the future and education of the children. Some of the guardians are not having any income and are really struggling to meet the ends means. The study made the following recommendations: The guardians as well as community members need to be equipped with information with regard to substance abuse. More strategies should be put in place with regard to support services by professionals to render to guardians. Guardians should be involved in the development of the children. Guardians should be involved in the schoolwork of the children to monitor and evaluate the performance. All the community members should be involved and should come up with strategies that could bring preventative services to the community members including children.

- Description: Non-disclosure of HIV/AIDS status is a topical issue in South Africa and across the globe. This study explored the ramifications of status non-disclosure by people living with HIV/AIDS (PLWHA) in Alice, Eastern Cape. The study aimed to explore the benefits and opportunities associated with HIV/AIDS disclosure; to examine the underlying factors discouraging Alice PLWHA from disclosing their status; to ascertain the ramifications of HIV/AIDS non-disclosure and to describe the coping strategies PLWHA and their families adopt in dealing with the ramifications of non-disclosure. The study employed the qualitative case study design, which was underpinned by the interpretive paradigm. The key informant’s method, in-depth interviews and focus group discussions were the main data collection methods. The sample of 35 participants was selected through the purposive and snowballing sampling technique. This sample comprised of 10 PLWHA, 20 family members and 5 key informants. The data collected from this sample was analysed through thematic content analysis. Findings indicated that PLWHA who disclosed their status accessed benefits and opportunities such as medication, psychosocial support, employment and the helping hands needed to manage their illness. In addition, the findings revealed that stigma, discrimination and socio-cultural factors inhibited some PLWHA from disclosing their status. Consequently, non-disclosure resulted in PLWHA experiencing ramifications such ramifications such as internal stigma, conflict in relationships, diminished career and educational achievement.

- Description: The thesis engages with the photographic collection of Dr Pauline Ingle, an amateur photographer who lived and worked in the former Transkei as a medical doctor from 1948-1976. As a visual history project situated within critical visual studies, the thesis is concerned to attend to the disciplinary optics that have conditioned seeing and constituted genres; but also the ways in which these genres have constituted subjects and corralled them into positions commensurate with the spatialised demarcations of the rural and the urban, and the attendant associations of tradition and modernity. The thesis begins by exploring the biography of Pauline Ingle and tracks the movement of the photographs from a private collection into the public realm and its constitution as an archive. The thesis then moves into a discussion of the key determinants of the ethnographic genre and its entwinement with the discipline of anthropology, as a foundation against which to investigate the limits of reading her images within this genre and the disruptions that are discernible through an aesthetics of proximity and forms of image-making that do not control the visual field. Through a theorisation that proposes the image as an act, various readings are brought to bear on the images through the lens of the social and political. Mobilising the concepts of social acts and acts of citizenship, allows for a reading that breaks with the disciplinary conditioning that has fixed subject positions into ‘the native subject’ and the ‘liberal subject’ and calls into question the construction of the human. By proposing the subject as migrant, is to signal that the question of the human/subject is more complex and convoluted than previously thought.

- Description: Background: The initiation of ante-natal care booking is universally recommended in the first trimester of pregnancy. While working in the Oliver Reginald Tambo district in the Eastern Cape Department of Health, the researcher noticed that late booking was the norm in all sub-districts, especially in the King Sabata Dalindyebo (KSD) sub-district, resulting in impaired antenatal care and an increased potential for adverse outcomes such as maternal mortalities. Purpose of the study: The purpose of the study was to explore and describe the reasons for late booking for antenatal care by pregnant women in the KSD sub-district. Objectives: The objective of the study was to determine reasons why women were booking late for antenatal in KSD sub district. Methods: Thirteen in-depth, unstructured interviews were conducted with late bookers (i.e., those who sought antenatal care (ANC) after twenty weeks of pregnancy) between July and August 2015. The interviews were recorded and, subsequently, transcribed by a reputable linguist from Walter Sisulu University (WSU) and analysed using Creswell’s thematic analysis model. Findings: The average gestational age of booking was 22 weeks (ranging from 22 to 28 weeks). Most women were teenagers and young unmarried women, most of whom were still attending school. All were unemployed. Most had experienced previous pregnancies. All these women delayed attending clinic early due to their ignorance of the exact gestational period for one to start the clinic. Although most of the women did not have direct reasons, the bulk of their reasons for delays were linked to long distances being travelled, leading to the payment of expensive taxi fees. This may also be attributed to cultural factors that seem to promote a veil of secrecy regarding pregnancy, the desire for visual evidence of pregnancy first and the practice of married women having to care for sick relatives. Conclusion: Poor access to clinics is a fundamental systemic failure and a major contributor and one of the reasons why women delayed in attending antenatal care clinics. Low socio economic status and cultural beliefs, coupled with long distance and expensive taxi fare, are other reasons for late booking.

The study sought to investigate whether the current records management practices upkeep or demoralize accountability and ultimate service delivery in the local municipalities. These are the objectives that were intended to be accomplished by the study: To find out the role of the provincial archives in the records management practices in Pixely ka Seme in the Northern Cape Province; To determine the extent to which records management practices in the Pixely ka Seme District in the Northern Cape Province comply with the legal and regulatory requirements; and To assess the impact records management practices on service delivery in the Pixely ka Seme District in the Northern Cape Province. Geographical Area; The district is comprised of eight local municipalities: Ubuntu, Umsobomvu, Emthanjeni, Kareeberg, Renosterberg, Thembelihle, Siyathemba and Siyancuma. Its main town is De Aar. Traffic flows through the region, linking the major industrial areas of the country. The area has a low rainfall, while the largest river in South Africa flows through it. Two of the major dams in South Africa, the Vanderkloof and Gariep Dams, are situated on the borders of the district municipality. Main Economic Sectors; Finance and business services (22.5percent), manufacturing (17.4percent), trade and accommodation (15.4percent), government services (12.9percent), transport and communication (11.3percent), mining (6.8percent), community and social services (5.6percent), construction (3.3percent), agriculture (2.7percent) Mixed methods were used for the investigation. Questionnaires and in depth interviews were used to collect data. Purposive sampling method was used to identify interview participants and adopted open ended questions to collect all necessary information by a questionnaire. The total population of the study was the Pixely ka Seme District employees in the Northern Cape Province. The Records Management Officials from eight local municipalities. The study sampled 18 participants but ended completing the investigation on 9 participants purposively. Total of Nine; 5 (56percent) of the participants were females while 4 (44percent) were males. The process was made possible through the use of purposive sampling to have the targeted respondents of the study. The study was enclosed within the theoretical frame of the “Life Cycle of a record” model and “Continuum model” to outline the whole process of record keeping discipline. The study discovered that records management negatively affected timely, effective and efficient accountability and in terms of audit results and service delivery. The results of the study revealed the dominance of the females in the records management practices in the Pixely ka Seme District. This finding was used was to analyze the impact of gender equality in the records management practices in the district. In this study, there is of a high number of females as compared to males and the study concluded that females led the records management structure in the Pixely Ka Seme District. Furthermore, the age range in this study proved to be one of the major factors that led to poor records management practice in the District. In addition, that qualification in relation to records management is the major hindrance in effective records management in the in the Pixely Ka Seme District in Northern Cape Province. Hereinafter, The Provincial Archives is not involved at all in the records management practices in the Northern Cape Province in the Pixely Ka Seme District. A large number of the municipalities do not have records management policies in place for the practice of proper records management. It is evident that records management compliance in compromised in this regard. A significant large number of the municipalities function without a legislative provision in terms of its record keeping. The study recommended that municipalities should now employ more and qualified records managers to rescue institutional records and the image of the organization. South African Local Government Association Records Management Forum (SALGA) as a municipal advocate must emphasize and command that municipalities must employ records managers at a managerial level to improve records section and professionalism in the field of records.

- Description: Smallholder farmers have been growing food in their communities, but some are still food insecure. Therefore, appropriate food systems are very important for smallholder farmers’ self-reliance as well as food and nutrition security. The study focuses only on community and regional maize food systems for rural households. The main aim of this study was to investigate the regional and community food systems for smallholder maize farmers in Mqanduli. The objectives of the study were to profile smallholder maize farmers, describing the existing maize food systems and patterns in Mqanduli and also to determine factors that influence farmers’ participation in local or regional markets. Availability or convenient sampling and random sampling techniques were used to collect primary data from smallholder maize farmers. Descriptive statistics was used to profile smallholder farmers, as well as, in describing the existing maize food systems at Mqanduli. The binary logistic regression model was used to analyse the variables that had influenced the smallholder famers’ participation in markets. Descriptive results revealed that, smallholder maize farmers in Mqanduli are characterised by high participation in both local and regional markets. Moreover, they utilized both community and regional food systems. Logistic regression results indicated that, out of 11 variables included in the analysis as factors influencing farmers’ participation, 6 of them (age, level of education, market information, distance, access to credit and extension visit) were found to be significant and 5 (gender, amount of land, transport availability etc) were not significant. However, access to credit and distance were found to be the most significant variables, showing a positive relationship to smallholder maize producer`s market participation. Therefore, it was recommended that, there must be more investment in research by government and policy makers when it comes to food systems especially in rural areas, to enhance smallholders’ livelihood. More access to credit is also needed by farmers in order to be able to market their produces.

- Description: Background: Alcohol use prevalence has been found to be higher than 50 percent at some universities in South Africa. It is against this background that this study aimed to establish the relationship between alcohol use, knowledge of alcohol-attributable health conditions and biographical characteristics. Literature review: The study was based on a review of literature on prevalence and patterns of alcohol use among university students, knowledge of alcohol-attributable chronic diseases, foetal alcohol syndrome, sexual and reproductive health and alcohol use measurement. Methodology: Data were collected from 213 undergraduate students enrolled for the Statistics service courses on two campuses of the same university. The Mann-Whitney normal approximation and the Kruskal-Wallis tests were used to compare health knowledge across levels of alcohol use and biographical characteristics. The chi-squared test and multiple logistic regression analysis were used to determine the significance and patterns of associations between alcohol use and health knowledge and biographical characteristics. Results: The prevalence rates of alcohol use and risky alcohol use were found to be 58.2 percent and 42.7 percent, respectively. The mean health knowledge was 42.9 percent, which, is rather low. Males [OR=0.3; 95 percentCI (0.18; 0.68)], returning students [OR=0.5; 95 percentCI (0.25; 0.94)] and those with employed fathers [OR=2.3; 95 percentCI (1.19; 4.47)] were found to be at a higher risk of alcohol use. Health knowledge was significantly higher among alcohol users (Z=-2.7; p=0.0074) and those whose fathers had a post matric education (𝜒2=6.4; p=0.0410) and/or employment (Z=-2.7; p=0.0064). Conclusion: While prevalence rates of alcohol use and risky alcohol were high, health knowledge was disappointingly low. This suggests need for interventions designed to minimise alcohol use while at the same time increasing health knowledge.

- Description: Background: Alcohol use prevalence has been found to be higher than 50 percent at some universities in South Africa. It is against this background that this study aimed to establish the relationship between alcohol use, knowledge of alcohol-attributable health conditions and biographical characteristics. Literature review: The study was based on a review of literature on prevalence and patterns of alcohol use among university students, knowledge of alcohol-attributable chronic diseases, foetal alcohol syndrome, sexual and reproductive health and alcohol use measurement. Methodology: Data were collected from 213 undergraduate students enrolled for the Statistics service courses on two campuses of the same university. The Mann-Whitney normal approximation and the Kruskal-Wallis tests were used to compare health knowledge across levels of alcohol use and biographical characteristics. The chi-squared test and multiple logistic regression analysis were used to determine the significance and patterns of associations between alcohol use and health knowledge and biographical characteristics. Results: The prevalence rates of alcohol use and risky alcohol use were found to be 58.2 percent and 42.7 percent, respectively. The mean health knowledge was 42.9 percent, which, is rather low.

- Description: Background: Non-communicable diseases are a growing public health concern and its prevalence is escalating exponentially, with a high frequency of morbidity, premature mortality, disability and loss of productivity. Since health education has become an important part of medical care, student nurses are potentially well suited to assist with the combat of these diseases. Early identification and treatment of modifiable risk factors among young adults would reduce the risk of developing cardio-metabolic diseases, thus, promoting health, prolonging life as well as saving costs related to healthcare. Objective: This study aimed to investigate the prevalence of cardio-metabolic risk factors among student nurses. Method: This was a descriptive cross sectional study, involving a convenience sample of 228 students during the educational year of 2017-2018 at Lilitha Collegeof Nursing in East London, South Africa. The WHO STEPwise standardized questionnaire was used to collect information on socio-demographic data (age, gender, year of study) and behavioural characteristics (smoking, alcohol consumption, physical inactivity, and dietary intake) of the participants. Anthropometric screening included measurement of height, weight and waist circumference. The biochemical screening included measurement of blood pressure and determination of fasting blood glucose concentration. Only students with complete data set were included in the data analysis. Statistical Package for Social Science (SPSS) version 23.0 was employed for descriptive and inferential analysis. Results: About half (41.7 percent) of the study participants were between the ages of 21 to 25 years and majority were females (67.5 percent).The prevalence of overweight and obesity were found to be 33 percent and 44 percent respectively. The prevalence of overweight was higher in males (44.6 percent), while females (53.9 percent) had higher prevalence of obesity. Female gender and increasing age are the only independent predictors of obesity. Results on blood pressure measurement showed that 25 percent of the participants had elevated blood pressure, and 22 percent were on stage 1 of hypertension while 2 percent were on stage 2. According to Joint National Committee on hypertension (JNC)’s criteria for defining hypertension, 44 percent of the participants had pre hypertension and 11percent had hypertension, diabetes and vegetables consumption were statistically associated with hypertension. The prevalence of pre-diabetes and diabetes was 6 percent and 7 percent respectively. Only abdominal obesity measured by waistto- hip ratio had a significant relationship with diabetes. Just 4.8 percent of the participants smoked daily and 33.3 percent consumed alcohol. Regarding physical activity, males were more active (60.8 percent) compared to females (54.8 percent). Conclusion: A high burden of overweight, obesity, and physical inactivity was observed among student nurses in East London. Screening for cardio-metabolic risk factors (CMRFs) among nursing students and implementation of intervention programs are recommended. Programs to raise awareness about CMRFs, encourage young adult students to adopt a healthy dietary behaviour and promote physical exercise should be initiated.

- Description: Essential oil of rose scented-geranium is highly versatile and this makes it a very important essential oil in aromatherapy, medicine and cosmetics as well as in flavouring of food and drinks for different industries. The value of the essential oil is directly related to the quality of the oil. Therefore, it is important that the geranium growers take good care of agricultural practices in the production of essential oils as it is a crucial step where oil quality and yield is either obtained or lost. Thus, growing conditions and harvesting time must be cautiously established and controlled including herbage drying to ensure optimum yields and high quality of rose-scented geranium oil. The geranium oil production industry in South Africa is still expanding and oil yield & quality variation is important. This study was undertaken to determine the effects of herbage drying and method, leaf age and paclobutrazol concentrations on oil yield and quality of rose-scented geranium. The responses of oil yield and quality to drying effect was conducted on plant materials which were harvested from the University of Fort Hare Research Farm and glasshouse in December 2014 and October 2015. To determine the effect of drying method on essential oil yield and composition of rose-scented geranium the harvested leaves were dried in direct sunlight (20-35℃) and in a shade conditions (25℃/room temperature). Essential oil was obtained by hydro-distillation using a Clevenger apparatus. The oil samples were analysed by gas chromatography (GC) at the Dohne Agricultural institute. The major components of the oil conducted under the shade method were Linalool (5.58 percent), Menthone (0.68 percent), Citronellol (36.14 percent), Geraniol (7.29 percent), CitronellylFormate (15.39 percent) and GeranylFormate (3.30 percent), whereas those that were sun dried comprised of Linalool (3.56percent), Menthone (0.76 percent), Citronellol (32.25 percent), Geraniol (6.49 percent), CitronellylFormate (14.84 percent) and GeranylFormate (3.15 percent). The analysis of variance showed that freshly dried herbage followed by shade drying is suitable for highest oil yield. In addition, changes in essential oil composition and oil yield with leaf age in rose-scented geranium (Pelargonium capitatum x P. radens cv. Rose) were investigated in a glasshouse of the University of Fort Hare, during January to April and April to August 2012. The plants were allowed to grow to about 12-leaf stage. From top to bottom, the leaves were put into five groups (each group comprising two successive leaves, Pairs 1, 2, 3, 4 and 5). Leaf growth (leaf fresh and dry mass), and essential oil yield and composition data were collected and compared. The results indicated that, leaf fresh and dry mass data were significantly lower in the top-most (youngest leaves) as compared with the rest of the leaf pairs harvested. Essential oil in the youngest leaves was colourless, but as the leaves advanced with age, the oil tended to have a blue-green colour. Oil content (on dry mass basis) from the top to bottom, for Leaf Pairs 1, 2, 3, 4, and 5 were about 7.0, 4.9, 3.2, 2.4, 1.9 percent, respectively. Oil yield showed a significant increase in the second youngest pair of leaves and progressively declined, resulting in a significant lower yield in the oldest leaves. Leaf Pairs 1, 2, 3, 4 and 5, contributed about 19.3, 22.0, 17.71, 12.03 and 8.5 percent of the total yield per branch, respectively. Citronellol:Geraniol ratio was significantly lower in the young leaves than in the old leaves. Linalool and Geranylformate concentrations were the highest in the youngest leaves, and the opposite was observed in isomenthone. Other essential oil components did respond to leaf age. In support of research by Góra et al. (2002), Motsa et al. (2006) and Southwell and Stiff (1989), the current results indicate that early leaf age affects essential oil yield and composition. Thus, shorter regrowth cycles would increase essential oil yield and quality of rose-scented geranium. The paclobutrazol experiment was conducted in a glasshouse at the University of Fort Hare, Alice. A randomized complete block design with four replications was applied. One month after cutting back of the plants, PBZ was applied at the rates of 0, 100, 200 and 300 mg/l on the regrowth and harvested at four months of age. Data, such as chlorophyll content, plant circumference, plant height, fresh and dry mass and oil composition, were determined. The results highlighted that with an increase in PBZ concentration, total herbage mass and plant height tended to decline (Esmaielpour et al., 2011). Thus, in most cases herbage fresh and dry weight of treated plants had lower weight than the control. Paclobutrazol significantly reduced canopy circumference. There was no significant difference (P< 0.05) in oil yield and composition. Furthermore, observations showed that plants receiving PBZ had a deep green colour although the chlorophyll data did not show a significant difference. These results clearly show that PBZ helps geranium plants with compact canopy, which would enable farmers to increase income by increasing planting density, reducing distillation cost of the herbage volume and mass without reducing oil yield per plant. The findings, add another dimension to practical use of this hormone for commercial cultivation.

- Description: This thesis focuses on the developmental impact of rural-urban migration in Nigeria. While, recognising the negative impact of rural-urban migration, the study argues that in order to benefit internal migrants as well as rural development, there must be a paradigm shift to focus on how the benefits of migration on development can be achieved. It is proposed that rural-urban migration occurs as a response to economic, education, health, social and environmental factors. The challenges confronting rural areas are urban bias development paradigm pursued by the successive governments resulting in rural underdevelopment that exacerbates the rural urban disparity. And the neglect of agriculture in rural areas resulting from the discovery of oil in Nigeria. The study revealed that flawed policies adopted by successive Nigerian governments led to joblessness, entrenched social inequality and opportunities. One of the outcomes of these short-sighted policies was rural underdevelopment, which accelerated rural-urban migration in Nigeria. However, the study also demonstrates that the income flows from the migrants to the various rural households has contributed to improvement in the living standard of the households. The fragmentary approaches to rural development that is currently the case in Nigeria would not generate the required level of development and growth needed in the rural communities to improve the living standard. Thus, there is need for a policy framework in Nigeria, which would encourage the private sector to play a vital role in contributing their part in the provision of infrastructural facilities in the rural communities. Although this thesis is a case study of the impact of rural-urban migration on rural development in Nigeria, it can serve to appreciate the role migration can play in promoting development both in rural and urban areas in Nigeria and other Saharan Africa countries.

- Description: Energy is one of the most important factor to influence human lives. The increased in energy demand as well as the detrimental effects posed by emission of greenhouse gases due to continue use of fossil fuels for electricity generation has led to a renewed focus on energy production using renewable energy sources which are relatively cheap, clean and environmentally sustainable. Among the various renewable energy sources used so far, the Dye Synthesized Solar Cells (DSSCs), a form of photovoltaic device is reported for their better efficiencies despite their low cost of production and ability to work relatively under low light conditions. A recent report on the solar-to-electricity conversion efficiency of a typical DSSC sensitizer made from zinc based porphyrin dye coupled with sintered titanium(IV) oxide as semiconductor was 13 percent. In this study, 2,2-bipyridyl-4,4-dicarboxylic acid (bpydc) was used as mixed ligand and four dithiolate ligands; L1 = dipotassium ethoxycarbonyl-1-cyanoethylene-2,2-dithiolate, L2 = dipotassium bis(ethoxycarbonyl)ethane-2,2-dithiolate, L3 = dipotassium cyanodithio imidocarbonate and L4 = dipotassium 2,2-dicyanoethylene-2,2-dithiolate were synthesized while four alkyl thiourea ligands, L5 = 1,3-dimethyl thiourea, L6 = 1,3-diethyl thiourea, L7 = 1,3-diisopropyl thiourea and L8 = 1-methyl thiourea were purchased and used as supplied without further purification. These ligands were used to prepare eight ruthenium(II) complexes of mixed bipyridyl/dithiolate/thiourea. The compounds were characterised by elemental analysis and spectroscopic techniques, namely: Fourier transform infrared (FTIR), Nuclear Magnetic Resonance (NMR), ultraviolet-visible and photoluminescence (PL). Cyclic voltammetry (CV) and square wave voltammetry (SWV) were used for the electrochemical studies. Photoluminescence and UV-Vis spectroscopies were used for geometric and photophysical studies of the complexes respectively. FTIR spectra confirmed presence of functional groups in ligands and coordination of these ligands to ruthenium(II) ions to form complexes. The UV-Vis confirmed that the Ru(II) dithiolene complexes exhibited square planar geometries while the Ru(II) thiourea complexes gave octahedral geometries, this was deduced from the transitions assigned to the complexes. All the ruthenium(II) complexes synthesized showed photoluminescence properties that are suitable for light harvesting and application for dye-sensitized solar cells. Cyclic and square wave voltammetry show Ru(II) thiourea complexes have better redox properties when compared to Ru(II) dithiolate complexes which is ascribed to ligand strength field possibly due to contribution from the two bonded NCS groups.

- Description: There is an increasing dissatisfaction among teachers in South Africa. Teacher job dissatisfaction has been found to have negative impact on how teachers perform their jobs, is likely to influence teachers to leaving the teaching profession and impact negatively on learner achievement. Finding ways to combat the problems is of utmost importance. Leadership behaviours of school principals have been found to be one of the key factors that positively affect teacher job dissatisfaction. This qualitative study sought to understand leadership behaviours employed by rural school principals in relation to teacher job dissatisfaction. This was a case study of three schools in the Butterworth Education District in the Eastern Cape Province. A total of three principals and twelve teachers participated in the study. Semi-structured interviews and documentary analysis were data collection instruments utilised in this study. House’s Path Goal Theory was identified as the relevant theory for understanding school principals’ leadership behaviours in relation to teacher job dissatisfaction. Findings revealed that, school principals are aware of the manifestations of teacher job dissatisfaction at their schools. However, teacher job satisfaction does not feature as an agenda item in both staff and school management meetings. Moreover school principals were found to be employing various leadership behaviours to respond to different manifestations of teacher job dissatisfaction. Leadership behaviours like participative and transformational were found to have a positive impact on teacher job dissatisfaction. Directive and laissez-faire were found not suitable in improving teacher job dissatisfaction. Findings also unearthed tensions between school principals’ leadership behaviours and teachers’ expectations on how principals should lead in relation to teacher job dissatisfaction. This study proposes that, as leaders school principals should act in both formal and informal ways to build teacher commitment in their organizations and influence teachers to achieve the goals and objectives of the school. School principals should create platforms where teacher job dissatisfaction is discussed and strategies to improve it are explored. This would help them to be aware of how their leadership behaviours impact on teacher job satisfaction and thereby make conscientious decisions to improve the level of teacher job dissatisfaction.

- Description: There is an increasing dissatisfaction among teachers in South Africa. Teacher job dissatisfaction has been found to have negative impact on how teachers perform their jobs, is likely to influence teachers to leaving the teaching profession and impact negatively on learner achievement. Finding ways to combat the problems is of utmost importance. Leadership behaviours of school principals have been found to be one of the key factors that positively affect teacher job dissatisfaction. This qualitative study sought to understand leadership behaviours employed by rural school principals in relation to teacher job dissatisfaction. This was a case study of three schools in the Butterworth Education District in the Eastern Cape Province. A total of three principals and twelve teachers participated in the study. Semi-structured interviews and documentary analysis were data collection instruments utilised in this study. House’s Path Goal Theory was identified as the relevant theory for understanding school principals’ leadership behaviours in relation to teacher job dissatisfaction. Findings revealed that, school principals are aware of the manifestations of teacher job dissatisfaction at their schools. However, teacher job satisfaction does not feature as an agenda item in both staff and school management meetings. Moreover school principals were found to be employing various leadership behaviours to respond to different manifestations of teacher job dissatisfaction. Leadership behaviours like participative and transformational were found to have a positive impact on teacher job dissatisfaction. Directive and laissez-faire were found not suitable in improving teacher job dissatisfaction. Findings also unearthed tensions between school principals’ leadership behaviours and teachers’ expectations on how principals should lead in relation to teacher job dissatisfaction. This study proposes that, as leaders school principals should act in both formal and informal ways to build teacher commitment in their organizations and influence teachers to achieve the goals and objectives of the school. School principals should create platforms where teacher job dissatisfaction is discussed and strategies to improve it are explored. This would help them to be aware of how their leadership behaviours impact on teacher job satisfaction and thereby make conscientious decisions to improve the level of teacher job dissatisfaction.
