- Description: Background. As a result of the AIDS pandemic, many people areimmuno compromised andopportunistic fungal infections (OFIs) such as candidiasis are common. Despite the widespread use of medicinal plants in South Africa, there is a dearth of knowledge regarding the use of such plants in the management of these infections. This study evaluates three South African medicinal plants (Arctotis arctotoides, Pittosporum viridiflorum, and Gasteria bicolor) traditionally used in the treatment of OFIs in HIV/AIDS patients, in the Eastern Cape Province, South Africa. Materials and methods. A six-stage process of documentation, evaluation and analysis of results was conducted: (1) Selection of medicinal plants most frequently used in the treatment of OFIs through ethnomedical studies and the survey of specialised literature; (2) Collection and preparation of the extract of each plant; (3) Antifungal evaluation of the crude plant extracts. (4) Phytochemical and antioxidant evaluation of the active crude plant extracts; (5) Cytotoxicity evaluation of the bioactive extracts using the Chang liver cell line, and (6) Statistical analysis of the results. Ethnobotanical information was obtained through interviews with traditional healers and AIDS patients with the aid of semi-structured questionnaires, direct observations and by reviewing studies reported in the literature. Following the approval from the University of Fort Hare‘s Ethics Committee, 101 HIV/AIDS patients were recruited through convenience sampling into an anonymous cross-sectional questionnaire study. The agar diffusion and micro-dilution methods were used to determine the antifungal activities of the hexane, acetone and aqueous extracts of A. arctotoides, G. bicolor and P. viridiflorum against 10 opportunistic fungi.

- Description: This study is based on student lifestyle and its contribution to personal victimization at University of Fort Hare in Alice campus. Social Science researchers such as Fisher, Sloan, Cullen, and Lu (1998) claim that there are many incidents of criminal victimization occurring on and off university campuses. The main purpose of this study is to find out whether there is any correlation between student lifestyle and personal victimization. There are many theories, concepts and available information regarding the issue of personal victimization among students, however, this notion is thriving, especially in higher institutions. The study examined the research objectives through lenses of theories such as lifestyle exposure theory, routine activities theory, rational choice theory which serve to elaborate more about the research topic. In this study data was collected using interviews and self-administered questionnaires for triangulation purposes. Some of the findings in this study were that there is vast majority of students who suffer from personal victimization on and off-campus due to students’ different lifestyles and lack of legal responsibility by the institution. First year females were found to be the majority of students who suffer from personal victimization due to their vulnerability in their residences. Based on these findings, recommendations such as tightening security measures around campus, educating students regarding victimization, and collaboration of the university with police officials were made.

- Description: Gums are soluble plant exudates rich in complex carbohydrates. In primates, the consumption of gum (gummivory) has been described as a primitive, fall-back diet exhibited when other food sources become scarce, particularly during dry periods. In apparent support for this interpretation, gummivory is often observed in nocturnal strepsirhines (tooth-combed primates) believed to have retained many primitive features. The complex carbohydrates in gums, however, are also known to be difficult to digest, and require particular alimentary adaptations. The hypothesis of a primitive diet predicts that gummivorous strepsirhines should use homologous digestive strategies, while the presence of different digestive adaptations in different lineages would suggest convergent evolution. I compared the digestive adaptations to gummivory in two small strepsirhine taxa, African lesser bushbabies (Galago moholi) and Malagasy reddish-grey mouse lemurs (Microcebus griseorufus). Both taxa digest gum primarily by fermentation, and have enlarged caeca for this process, but only G. moholi has an ansa coli in which digestion can be continued. In captive feeding experiments, the faeces of wild-caught G. moholi and M. griseorufus showed no significant difference in their digestive efficiency of gum compared with a control food (banana), and the banana and gum samples showed no significant difference in nutrient concentration and overall composition. To gain a broader understanding of the origins of gummivory in strepsirhines, I used a phylogenetic method to reconstruct their dietary evolution. My results indicate that gummivory evolved convergently in several primate lineages, apparently in response to environmental hypervariability. I conducted biochemical analyses of the secondary compounds found in gums that are regularly consumed, and preliminary results show that Commiphora spp. have a number of compounds, while Acacia spp. show no such traces. The absence of secondary compounds from M. griseorufus faeces suggests that the animals have physiological means for either converting them into digestible products or detoxifying and excreting them in their urine. Finally, I compared the distribution patterns of G. moholi and M. griseorufus with climatic parameters; both study taxa inhabit regions in which the dry season is characterised by little to no rainfall, a drought that may persist for months. Similar climatic regions are occupied by other gum-feeders, including the marsupial gliders (Petauridae) of Australia.

- Description: The dawn of democracy in South Africa led to the development of Language in Education Policy (LiEP) as one of the pieces of legislations that promote languages in schools where parents, learners, who have come of age may choose a language for instruction. LiEP, together with the Constitution of South Africa, promote equal value of all eleven official languages spoken in this country. The promotion of language policies clearly shows that language is the bedrock of the academic development of every child. Unfortunately, Spaull, Van der Berg, Wills, Gustafsson and Kotzè (2016) found that South African Foundation Phase learners lack the most basic skill needed for academic achievement, reading for meaning. Spaull et.al (2016) findings show that language problems start during the early years of schooling. This study aimed at finding out the perceptions of school stakeholders about the use of English as LoLT in Grade 9 Social Sciences, and it is located in the Interpretivist Paradigm. In this study, stakeholders are learners because they are central to learning, parents, as they have the responsibility of choosing LoLT for their children and assist them in their schooling career. Lastly, teachers are stakeholders because of their critical role of imparting knowledge and skills during classroom interaction. The researcher uses a Qualitative approach to identify data-collecting tools suitable for this research, and chooses semi-structured interviews and observations. Semi-structured interviews are flexible and allow deeper probing during the interview. The sample consists of nine Grade 9 learners, three teachers of Grade 9 Social Sciences and six parents from the School Governing Body (SGB). The aim of conducting observations was to find out the language used by learners and teachers during classroom interaction. This study found out that most participants prefer learning Social Sciences in English than in isiXhosa. They are aware of the challenges experienced in the classroom when learning in English but they still choose it. From the sample used, participants clearly indicate that learning in English causes some barriers in the learning and teaching process. However, it also became clear that the benefits associated with learning in English make it difficult to put it at the same level as other languages and participants do not link mother tongue to career opportunities. It is also evident that English will enjoy its hegemony until such time that all stakeholders in Education view the mother tongue as a foundation for learning other languages and as a resource as well so that they can use it in the classroom to understand the content. Policy developers must look deeply into the question of LoLT so that learners receive instruction in a language that will assist them in improved academic performance. Teachers must be equipped with adequate skills to assist learners in developing reading and comprehension skills in the classroom. There is a dire need to develop the culture of reading in rural school learners; and teachers must expose learners to a variety of English reading material.

- Description: Death and bereavement are prevalent in Zimbabwe due to HIV/AIDS and other illnesses. It is estimated that a large population of school going learners have lost one or both parents and have become orphans. The aim of the study was two-fold: to understand the bereavement experiences of orphaned learners and to examine how such experiences can inform school counselling services. A multiple case study involving 13 school children and four school counsellors from two secondary schools in Harare Metropolitan Region was conducted. Each of the 17 participants was viewed as a bounded case due to his or her individual unique experiences. An interpretive phenomenological approach was employed to collect and analyse the data. All the cases were purposively selected as they were bearers of crucial information on bereavement experiences and bereavement counselling. The study established nine (9) key findings. First, it was found that the type of attachments and support systems the child had were contributory to the way the child experienced bereavement. Second, it was established that although learners manifested emotional pain, they found it difficult to verbalise it. Third, the study found that cultural practices either exacerbate or work for the better for bereaved children as some were seen to enhance their livelihood whilst some were detrimental and oppressive. Fourth, it was established that bereavement triggered philosophical and reflexive reactions on the part of bereaved children. The deaths of the parents resulted in them reflecting on the three phases of their life trajectories: life before death; at the time of death; and after death. Fifth, it was also established in the study that there was a mismatch in what children and counsellors claimed to be happening in secondary schools pertaining bereavement counselling provisioning. Sixth, the study found that most children did not receive any bereavement counselling in schools. Only three out of the 13 learner cases interviewed in this study had a teacher in the school talk to them about loss of their parents. In some instances, a child’s bereavement was only discovered through the grapevine or when this researcher got to the school. Seventh, it was established that although counsellors were qualified as both teachers and counsellors, they lacked confidence in dealing with sensitive issues such as bereavement. Eighth, the study also found that although there is a lot of death in Zimbabwe the counselling syllabi lacked focus on bereavement counselling. Ninth, it was also discovered that teachers who were not assigned to counselling duties had negative attitudes towards counselling, a matter which has serious consequences for the bereaved learners. Based on the above findings, the study concludes that bereaved children experienced a variety of circumstances that impacted both positively and negatively on their schooling and rendered them in need of bereavement counselling. It also concludes that bereaved learners in selected Harare schools were not receiving adequate bereavement counselling; schools neither had policies nor laid down procedures on bereavement counselling. For further research, the study recommends that there should be research focusing on methodologies designed to access children’s innermost feelings of emotional pain. There should be further research on the nature of the relationship between a child’s bereavement and educational experiences. Studies involving other bereaved populations, such as, children from rural areas and primary school children should be carried out in order to gain insights on how the phenomenon is experienced by different age groups in different contexts. To improve counselling practice in schools, the study recommends that there should be capacity building programmes aimed at assisting teachers to deal with bereavement counselling. School bereavement counselling should explore collaboration with other stakeholders such as peers, care givers and government as well as non-governmental organisations. Above all, the study recommends that schools should be proactive and have school bereavement policies and procedures on bereavement counselling.

- Description: The aim of this paper is to establish the impact of citizen’s protests on the performance of municipalities with particular reference to Nelson Mandela Bay Metropolitan Municipality. The basis for this study is the wave of strikes that are directed towards municipalities bearing demands for the delivery of basic services. The protests give an indication that municipalities throughout the country are faced with challenges in carrying out their constitutional mandate of delivering basic services and developing the socio-economic status of their constituencies. It thus becomes crucial to get a grasp of the causal factors and to understand the impact of such protest on the performance of municipalities, in order to develop relevant intervention strategies. The research aims to identify the trends and define the nature of these service delivery protests. In order to preserve democracy government ought to take note of the demonstrations because they are a re-occurrence of the past. During the apartheid regime, non-voting civilians used violent protests to raise their dissatisfaction with the government of the day; primarily the protests were aimed at disorganizing and bringing pressure to the government. The situation is different because nowadays citizens have various platforms to raise their concerns hence it becomes crucial to analyse the protests because they may be an indication that the various platforms are not functional and that people want to raise a vote of no confidence to the reigning party. The research entails an overview of local government, the constitutional mandate and developmental role of local government. The paper will also provide a brief synopsis on the state of affairs with regards to the delivery of basic services in Nelson Mandela Bay Metropolitan Municipality. In conclusion there is going to be a list of recommendation based on the findings of this investigation. The recommendations will assist Nelson Mandela Bay Metropolitan Municipality and other municipalities in developing their strategies of delivering services in an effective and efficient manner thus giving meaning to the objectives of the constitution.

- Description: Consumption has been and remains the main contributor to gross domestic product (GDP) growth in South Africa. Household debt on the other side has remained high over the years. This study examined the relationship between household debt and consumption spending, for the period between 1994 and 2013. The Johansen cointegration technique and the Vector error correction model (VECM) were utilised to test the long run and short run relationships between the variables. The Granger causality test was also employed to test the direction of causality between the variables. Results from this study have revealed that a relationship exists between household debt and consumption spending in South Africa and they have also showed that this relationship flows from household debt to consumption spending. The implications of these results are that consumption spending may be increased through other measures rather than through increasing debt. The study therefore recommends that policy makers avail more investment opportunities for households and to also create employment in a bid to increase the income of households which can then be used to increase household consumption rather than the use of debt.

- Description: Most land is still state owned and is granted to users through traditional authorities. Even though the government has undertaken some programmes to reduce rural poverty and has initiated land reform programmes, improved service delivery and formed new water rights legislation in rural areas, the problem of low crop production still persists among South African farmers. The study was undertaken to identify different farmers’ aspirations and goals for expanding their crop production from homestead gardening to irrigation plots in Mhlontlo Local Municipality, in the Eastern Cape of South Africa. The central problem is that smallholder farmers are not expanding their scale of crop production even though they have access to natural capital which includes land and water. The broad objective of the study was to determine the aspirations and goals of farmers to expand irrigation crop production from homestead gardens to irrigation plots. The specific objectives of the study were to assess factors that addressed smallholder farmers’ aspirations and goals to expand crop production, to identify challenges that smallholder farmers encountered in expanding from homestead gardens to irrigation plots and to determine the current state of homestead gardens and irrigation plots. A list of 20 goals were identified from the field survey with 54 homestead food gardeners and 50 smallholder irrigation farmers in the different villages of the Mhlontlo Local Municipality. Random sampling was used to select the farmers who were asked to score the identified farm enterprise goals in terms of their relative importance. The goals were categorised into five factors using Gasson goal ranking methods which ranked goals on the basis of intrinsic, expressive, instrumental, and social criteria. The next step was to determine the standard deviations and means of the ranked goals. Descriptive statistics was then used to profile the farmers according to such factors as age, gender, years of farm experience, types of plot, the availability of water and land for crop production, the income farmers generate from the sale of crops produced and these are cross-tabulated with their goal rankings. The Logit model was used to estimate the probability that farmers would belong to a particular goal ranking and performance category. The logit model was also used to identify the factors that influence the expansion of the cropped area. The results revealed that maize production and land size where significant at 1%. Age and type of irrigation used were also positively significant at 1%. The results also revealed that the adoption of agricultural technology by smallholder irrigation farmers and homestead food gardens contributed to better quality produce.

- Description: Sugarcane is a major crop in many countries. It is the most abundant lignocellulosic material in tropical countries such as South Africa. It is one of the plants with the highest bioconversion efficiency. The sugarcane crop is able to efficiently fix solar energy, yielding some 55 tons of dry matter per hectare of land annually. After harvest, the crop produces sugar juice and bagasse. Sugarcane bagasse is a residue that results from the crushing of sugarcane in the sugar industry. It is a renewable feedstock that can be used for power generation and manufacturing cellulosic ethanol. As biomass, sugarcane bagasse holds promise as a fuel source since it can produce more than enough electricity and heat energy to supply the needs of a common sugar factory. However, in the sugarcane industry the bagasse is currently burnt inefficiently in boilers that provide the heating for the industry. This project seeks to investigate the possibility of gasifying sugarcane bagasse as an efficient conversion technology. The investigation is necessary because fuel properties govern the gasifier design and ultimately, the gasification efficiency. Proximate and ultimate analysis of sugarcane bagasse was conducted after which the results were used to conduct a computer simulation of the mass and energy balance during gasification. The kinetic investigation undertaken through the TGA and DTG analyses revealed the activation energy and pre – exponential factor which were obtained by the model – free Kissinger method of kinetic analysis and were found to be 181.51 kJ/mol and 3.1 × 103/min respectively. The heating value of sugarcane bagasse was also measured and found to be 17.8 MJ/kg, which was used in the calculation of the conversion efficiency of the gasification process. Fuel properties, including moisture content and gasifier operating parameters were varied in order to determine optimum gasifier operating conditions that results in maximum conversion efficiency. The highest conversion efficiency was achieved at low moisture content after computer simulation of the gasification process. Moisture content also affected the volume of CO and H2 as the former decreases with increasing moisture content while the latter increases with increasing moisture content, accelerating the water – gas reaction. Scanning electron microscope fitted to an Energy dispersive X – ray spectroscopy was also used in order to view the shape and size distribution as well as determine the elemental composition of sugarcane bagasse. The results obtained established that the fuel properties and gasification conditions affect the conversion efficiency. During computer simulation, it was established that smaller particle size resulted in higher conversion efficiency. The smaller throat diameter also resulted in higher conversion efficiency. The throat angle of 25° also resulted in higher conversion efficiency. The temperature of input air was also found to be one of the major determining factors in terms of conversion efficiency. The dissertation presents the proximate and ultimate analysis results as well as the kinetic analysis results. The SEM/EDX analysis as well as the computer simulation results of the gasification process is also presented. The major contribution of this project was on the investigation of the gasification characteristics of sugarcane bagasse and the utilization of these in the design of a laboratory scale sugarcane bagasse gasifier with enhanced conversion efficiency through computer simulation.

- Description: Background: International research has clearly indicated that the world’s population is ageing: almost all countries in the world are experiencing a significant growth in the proportion of older persons in their population. This is also true for developing countries such as South Africa that are beginning to show signs and symptoms of an ageing population. Among Southern African Development Communities (SADC), South Africa has the highest number of ‘senior citizens’. Population reports indicate that the population of old people rose from paltry 2.8 million in 1996 to more than 4 million in 2011 and this is expected to skyrocket to seven million by 2030. In spite of the increasing number of senior citizens in socio-structural landscapes in South Africa, there is still lack of adequate, workable and effective policy frameworks for the wellbeing of the elderly. There is also paucity of psychological data of the elderly, especially along racial divides to determine whether the after-effects of apartheid still hold sway or not in post-apartheid South Africa. This study was conceived to investigate the psychological well-being of the elderly in Buffalo City, Eastern Cape, South Africa between two racial-ethnic elderly groups. The specific objectives of the study were to explore the relationship between the socio-demographic characteristics and psychological well-being of the black (Xhosa) and white (English) elderly in Buffalo City, South Africa and second, to validate the relationship between psychological well-being and physical activity, loneliness, spirituality/religiosity as well as ageism among the sampled population. The set-point theory, selective optimisation compensation theory (SOCT) as well as the continuity theory were employed to guide the conduct of the study. Method: Psychological measuring instruments were deployed to collect data for the study from a total of 301 elderly respondents in retirement and private individual homes (191 isiXhosa and 110 English speaking elderly). Both simple random sampling (SRS) and purposive sampling procedures were used to select the respondents. The measuring instruments included the Ryff Scales of Psychological Well-being (RSPWB), Physical Activity Scale for the Elderly (PASE), Assessment of Spiritual and Religious Sentiments Scale (ASPIRES), University of California at Los Angeles (UCLA) Loneliness Scale, the Palmore Ageism Survey scale and a biographical questionnaire. Data was analysed using MANOVA, One-way variance analysis and regression coefficient. The racial differences logically influenced the selection of the respondents for the study. Results: The study revealed a significant statistical relationship between physical activity (PA) and psychological well-being of the elderly, regardless of the sociodemographic variables. PA showed a significant relationship with psychological wellbeing of the elderly. The study also discovered that loneliness correlates significantly with all four of the psychological well-being scales. It shows that the higher the levels of loneliness experienced by the elderly, socio-demographic variables controlled, the lower the levels of psychological well-being in terms of autonomy, environmental mastery, purpose in life, and self-acceptance. However, with the exception of the relationship between loneliness and purpose in life, ethnic affiliation moderates autonomy, environmental mastery and self-acceptance. English elderly constantly experienced higher levels of autonomy than the isiXhosa elderly do with an increase in loneliness. The study also found a positive relationship between ageism and psychological well- being. However, with low levels of ageism, the English elderly, in comparison with the isiXhosa elderly, is likely to show higher levels of autonomy. In addition, a significant statistical relationship between ageism and environmental mastery and purpose in life was found among the isiXhosa elderly. Although, with an increase in ageism, there is a slight increase in autonomy in both groups, the English elderly throughout showed higher levels of autonomy than the isiXhosa elderly showed. The study found a positive relationship between religiosity/spirituality and psychological well-being of the elderly. However, race could moderate the relationship between prayer fulfillment and psychological well-being at all four levels (autonomy, environmental mastery, purpose in life, and self-acceptance). With an increase in prayer fulfillment, the autonomy of the English elderly increases fairly quickly, while the autonomy of the isiXhosa elderly decreases slightly. Comparatively, the study found that isiXhosa elderly reported lower levels of psychological well-being than the English elderly. Conclusion/Recommendation: The study concludes that there is the need to develop a solid national data bases on needs and use of services, and process of ageing in order to access research data to assist planning, dissemination, delivery and evaluation of effective service delivery for the elderly population in South Africa, especially along racial divides.

- Description: The traditional mandate of local government is to deliver sustainable services to communities. The evolution of local government has since put more emphasis on evidence based planning in the form of IDP and sound financial management. The relationship between the IDP and Budget is that, a) the IDP contains community needs, objectives and strategies on how these will be responded or dealt with by the municipality, and b) the budget is the financial plan to execute strategies that need to be employed. The purpose of the study was to examine challenges in integrated development plan and the budget alignment of Amathole District Municipality. The study moved from the premise that municipalities are different and ADM has been in the fore front in terms of producing IDP and Budget. The study therefore is based on the assumption that the Amathole District Municipality has challenges in the IDP and Budget alignment. The study proposed to give a background of the scholarly literature of the IDP and Budget of local government. The empirical survey and research methodology used in the study is described and explained in-depths and followed by data collection in the form of the questionnaire. The research findings of the empirical survey are then analysed and reported in statistical form.

- Description: This study examined the holiday and leisure aspirations of the new upper black middle class in East London using qualitative approach. The study investigated aspirations of the black middle class on international travels through the lens of Veblen’s (2002) conspicuous consumption theory which entails that black middle class citizens spend in order to assert their status and belongingness to the middle class. The aim of the study was to understand their holiday and leisure aspirations, what the idea is behind or what motivates their international travels, their travel experiences and class affirmations. This exploration included the challenges and frustrations such as Ebola scare, racism, issues with foreign exchange and variations from these international visits. Data was collected through interviews with upper black middle class who are based in the Buffalo City Metro Municipality in East London, Eastern Cape. Findings from this study revealed that consumption patterns of the emerging black middle class to diverge substantially from the other groups, in terms of greater signalling of social status via visible consumption and preoccupation with reducing an historical asset deficit. Various themes emerged as meanings attached to international travelling and leisure by those black middle class international travellers. These are sense of wealth, status, religion, self-esteem, sense of reward, bonding with friends and conspicuous/visible consumption.

- Description: The aim of this study was to investigate the relationship that exists between emotional stability, stress and work-family conflict among Standard Bank female employees. For this purpose data was collected from the female employees of Standard Banks in Alice, Fort Beaufort, King Williams and East London Town’s in the Eastern Cape. A sample of 72 female bank employees was drawn from the population. Neuroticism is the opposite of emotional stability and it was mostly often used in place of emotional stability in the study. Results of the study indicated that all study variables are significantly positively correlated with one another. The findings of this study is helpful in the banking industry in order to design human resources policies which will reduce the work-family conflict and decrease stress for female bank employees and for future research in respective topics. The implications of this study are discussed along with recommendations for future research and professional managerial practice.

- Description: This study investigated the psycho-social well-being of female students aged 18 to 27 who gave birth during cohabitation at one of South African university (University of Fort Hare, Alice Campus). It also investigated the challenges those female students face when they try to balance academics with motherhood. The study is underpinned by Ryff (1989) psychological well-being that suggested that psychological well-being is attained by achieving a state of balance affected by both challenging and rewarding life events. Purposive sampling was employed to select participants of the study and in-depth interview was used to generate data. Thematic analysis was engaged to analyse data. The study discovered that the psychological well-being of female students who gave birth during cohabitation is impaired in way that they experienced impaired environmental mastering, impaired good relationship with others, impaired self-acceptance, impaired personal growth however they show resilient. The study found that female students who gave birth during cohabitation are faced with numerous challenges such as discrimination, lack of support, depression in balancing academics with motherhood, lack of attachment with their children including poor academic performance.

- Description: Today the term ‘Information Technology’ (IT) is a buzz word globally. It is an indispensable tool in government departments and it enhances management, planning and organisation of all activities in the departments. Information Technology (IT) refers to equipments such as overhead and digital projectors, digital cameras, cell phones, Television recorders, language laboratories, printers, computers and all its components such as different soft wares, hard wares, Central Processing Units (CPU) etc. These machines are teaching aids just like pens, rulers, writing boards etc when they are used by teachers and become learning tools when they are used by learners. It can be argued that IT can be the life blood of management in schools because by using it all the departments in the institutions are managed and co-ordinated easily. The database containing information about the learners, the staff, the subjects offered, the compiling and filing of mark schedules are easily done and are available at any time on request. IT helps in the managing of learning and teaching. The main focus of this study is to explore the management of IT funding as a critical aspect of managing teaching and learning. Today without funds IT use would be impossible. Relevant soft wares for all subjects taught such as Mathematics, Biology, Physical Education Environmental Studies etc are managed and planned by the management of the institutions to enable teachers to teach effectively and efficiently and to make studies easy for the learners to understand and to do research on their own. When the IT equipments are used properly, fast, efficient and effective service delivery would be realized. All these technological tools aforementioned depend on the availability of funds in the institutions.

- Description: This study sought to evaluate the factors that affect the development of archives in the City of Johannesburg Municipality. The use of old records management strategies is posing serious challenges in most African countries and it is affecting the development of archives and records. Literature shows that most municipalities in Southern African countries have not adapted advance records management strategies like Integrated records management and Cloud systems for the realization of benefits of effectiveness and efficiency in records management. The history of Johannesburg municipality and the significance of records management in terms of leveraging effective service delivery raised critical concerns over the development of archives and records management. Proper management of records is the foundation of any government needs to provide services, to fulfil its obligation of accountability towards its citizens and protect their rights. According to the continuum model, the archivists and records managers need to be involved together with information systems designers in the creation of records keeping systems. The records continuum model emphasizes advanced records management strategies and systems in order to ensure the systematic preservation, retrieval and disposal of records. As the records management systems shift from the narrow physical records management as well as imaging into the broader electronic records world there is need for the municipality to embrace more advanced records management strategies like Outsource/Cloud service and integrated records management systems. In order to get a deeper understanding of the factors that affect the development of archives and records management; this study combined both qualitative and quantitative methodologies. The census method was used to select all the 80 members of the records management department in the metropolitan municipality. An in-depth interview schedule was conducted with 4 records managers in order to collect qualitative data. Questionnaires were distributed to 76 personnel in the records management department. Without an operational and effective policy in the department of records, there is no vanguard against unlawful records and archives access and corruption, which is affecting archives development and records management in the long run. The study established although email backups and archiving of files are important strategies, more effective and modern strategies like Integrated Records Management system across the entire organization and the cloud system have not been put in place. This is attributed to the lack of funding and IT expertise. The study concluded that that although training and skills development programs are being ii implemented, skills transfer is not fully taking place due to lack of; equipment, time, managerial support and post-training interventions as well monitoring and evaluation systems. The study recommends an integrated records management system, operationalization of the records management system, effective skills transfer programs, the competency-based model.

- Description: This study aimed at assessing the impact of communication on the sustainability of poverty alleviation programmes established for selected beneficiaries in the rural community of Lifajaneng. This is conducted with the purpose of understanding how the Mafeteng community engages in the poverty alleviation projects carried out within their area of residence, so as to encourage more commitment in participation. The conceptual framework for this study is the empowerment approach and the study is informed by two theories; the participatory communication theory and the diffusion of innovation theory. The study employed the mixed method approach to gather and analyze the data; that is using questionnaires, focus group discussions and face to face interviews to solicit for information from project participants and project managers. The quantitative data was presented and analyzed through charts and graphs buttressed with themes that emerged in the qualitative data. The study revealed that the sustainability of the poverty alleviation projects remains questionable due to a number of challenges. The results reflect that communities are more comfortable when the mother language (Sesotho) is used predominantly as the medium of communication. The results also reflected that meetings had a higher attendance rate if called for by local leaders through word of mouth followed by communications done telephonically. Mainstream media such as radio and newspapers were the least effective when mobilizing the communities for meetings related to the poverty alleviation projects in the poor community. The study also unfolded the following issues; lack of full participation and commitment of the beneficiaries, inadequate funding to allow sufficient training of the beneficiaries. This is because the funds had some strings attached and the beneficiaries had their own expectations of the funds, therefore the objectives and the limits of the funder did not match the objectives and the limitations of the beneficiaries. Hence, the end results are lack of motivation for the beneficiaries.

- Description: In this present era of sustainable energy development, photovoltaic modules which are based on amorphous silicon cells have immeasurable prospects of contributing meaningfully to the energy demand of the world at large. The global consciousness of environmental safety issues has birthed the rapid demand for the photovoltaic system. However, the production increase is mainly in bulk-type crystalline (c-Si) solar cells. Thus, to meet the high demand of the market, single junction amorphous silicon (a-Si:H) solar cells production must be encouraged through active research in that regard. This could also help to improve its efficiency and reliability. There has recently been a sharp decrease in the production cost of the bulk Si solar cell, but the a-Si:H solar cell still remains the most economically viable in comparison to the other PV technologies. Companies such as Sharp are currently developing large-scale a-Si:H solar modules that can produce an efficiency of 10.5% after the long-term degradation process. To date, a-Si:H is believed to be one of the most promising thin-film PV technologies (Saito et al., 1993; Hamakawa et al., 1994). The cost of a solar PV manufacturing fell by 6% in 2014 (Santa, 2014), this is in accordance with the 2008 cost production forecast; thus, the cost record stands at 0.20 per watt, as reported by the NPD Solar publisher. Amorphous silicon (a-Si) solar modules generate more kilowatt-hour (kWh) of electricity per kilowatt (kW) than crystalline silicon or other technologies of the same capacity of installation. Furthermore, a-Si:H modules have more functional hours per day. Single junction amorphous silicon (a-Si:H) modules can function beyond the peak sun hours, and they also have a better performance on a cloudy day. vii In other words, a 1kW PV system of a-Si:H is expected to generate more electricity per year in comparison to 1kW PV from other technologies, hence there is a low energy payback time. In this study, commercially available single junction amorphous silicon modules were bought from a local market and they were immediately deployed outdoors. The initial reading of the modules, which served as baseline reading, showed an average of 25% decrease in the modules performance, therefore, there is a need for a long term monitoring process to obtain the best and worst performing modules. Measuring the performance parameters of these PV modules under real sun light (IV) provides a better degradation assessment. This conventional assessment cannot provide an in-depth insight responsible for the variation and degradation of the performance parameters. More obscured parameters like recombination current and ideality factor were obtained from the dark IV measurements. However, this is still superficial in a way. The intrinsic parameters were obtained from scanning probe microscopy (SPM) and CV measurements. The study focuses on the degradation analysis of a-Si:H due to an increase in defect density. A rise in the defect concentration is a huge problem because it causes long-term solar cell degradation, which increases the recombination current and decreases the conversion efficiency. Furthermore, it decreases the photo-generating current and reduces the effective efficiency of the solar device. In other words, the electrical output decreases. This research investigates the reduction in a-Si:H modules’ maximum power, and correlates these with a hot spot formation. A PVPM IV tracer was used for the outdoor characterisation of the module’s temperature profile, while the IR camera was used to analyse the hot spot centre. A four probe IV/CV from NMU was used for the indoor assessment of smaller samples cleaved from both the affected and non-affected regions to characterise the electrical variations across the module viii samples. To be precise, in this study, a naturally degraded single junction amorphous silicon module was delaminated and its mechanical properties were analysed and correlated with the contact potential from a Kelvin probe force microscopy (KPFM).

- Description: During sports competitions, especially soccer many players and coaches would pray before, during and after the game. Sometimes they would pray when they score a goal. The behaviour has attracted a research interest wanting to know why they do what they do often. The purpose of the study was to understand and evaluate the perceptions of coaches and elite players who continuously use spiritual rituals before, during and after soccer games to influence competitive outcomes. This study was carried out under the guidance of the following key questions; (a) Do spiritual perceptions of elite players influence outcomes of soccer competitions? (b) Does a divergence in spiritual perception between coaches and players influence competitive outcomes? and (c) Are spiritual (ritual) perceptions of soccer coaches and elite players related to religiosity/psychological interventions? In this study, a mixed method of data collection was used to eliminate the biases inherent in single method research. Specifically, qualitative and quantitative methods involving questionnaire, interview and observation supported by secondary and primary literature were used to gather information that would provide answers to the raised key questions. The results show that spiritual ritual practices would not influence the outcome of soccer competitions. Secondly, the spiritual ritual divergence among players and coaches would not influence outcomes of soccer competitions. Thirdly, the results showed that the use of spiritual rituals among players was purely for personal reasons, while the coaches used spiritual rituals as psychological intervention strategy to prepare the team before a given competitive. The overall results show that coaches and players agreed that spiritual rituals interventions are used for psychological interventions more than spiritual interventions. The implications of these findings to the players and coaches are discussed linked with future research focus.
