- Description: Small to Medium sized Enterprises (SMEs) play an essential role and can be described as the crucial bread and butter of the South African economy. They have the potential to create employment and skills development opportunities pertinent for sustainable economic growth. The unfortunate part is that South African Small to Medium sized Enterprises have the lowest survival rates in the world, resulting in high rates of business failure and job losses. This is because the South African economy does not favour SMEs, which are often burdened with structural hurdles including access to funding, lack of access to markets, inadequate skills, uncompetitive regulatory frameworks and technological disruptions. A developing economy such as South Africa cannot grow if companies facing financial difficulty are constantly liquidated. This is because the liquidation system does not offer companies an opportunity to restructure and possibly function within the context of raised concerns. In order to facilitate sustainable SMEs growth, the legislature has come up with statutory mechanisms to support SMEs and save them from total liquidation. Most recently, the Companies Act 71 of 2008 Chapter 6 introduces a business rescue mechanism applicable to all business structures established under the Act. The purpose of business rescue is to provide companies in financial distress with opportunities to reorganise, strategize and come up with useful corporate reorganisation measures which are useful and efficient in saving the financially distressed company and possibly yielding a better return for the creditors than would have been the case if the company was liquidated. This new enactment is seen as both an improvement and necessary reform from its predecessor, judicial administration which has widely been condemned as a failure. However, despite this improvement, the application of the current business provisions to SMEs is questionable. Although Chapter 6 of the Act makes provision for SMEs, it also presents a number of stumbling blocks, including the fact that services of business rescue practitioners are out of reach for most SMEs in South Africa. The purpose of this study is to consider challenges faced by SMEs in the practical application of the current business rescue provisions. This study further emphasizes the importance of South African SMEs, whilst looking at their challenges and how the Companies Act 71 of 2008 provisions, regarding business rescue, assists SMEs. The study looks at the impediments of certain provisions of business rescue and proposes recommendations. , Thesis (MA) (Laws) -- University of Fort Hare, 2021

- Description: The epidemic of overweight or obesity conditions has become a public health concern in South Africa, and signifies major challenges of chronic diseases affecting the healthcare sector. Recent years have noted the increasing prevalence of gamification and development across all age groups. The rapid adoption and use of gamification as a tool to improve adult motivation and engagement when monitoring their health and wellness is an essential form of health intervention. Gamification allows its users to keep track of their health in real time and encourages an active healthy lifestyle behaviour. Research has found that there are factors that may inhibit the behavioural intention of adults to use gamification for health monitoring in the long term. These factors include cost or membership fees associated with gamification that uses Discovery Vitality and privacy concerns. The main aim of this research study was to develop a framework to influence the behavioural intention of adults to monitor their health through gamification making use of Discovery Vitality as the case study. The self-determination theory was used as the theoretical framework to ensure continuance usage of gamification for sustained health monitoring. A qualitative research approach was chosen for this study. The purposive sampling technique was selected to identify 20 adults between the ages of 18-59 years that are members of Discovery Vitality in East London, South Africa. Interviews were conducted with the 20 participants to identify the factors that will influence their behavioural intention to make use of gamification to monitor their health. After data collection, thematic analysis was used to analyse the data and the data provided by the participants was organised and summarised into relevant themes to answer the main research question. The study developed a framework which incorporated the four constructs of the self-determination theory, namely perceived autonomy, competence, relatedness and satisfaction of basic psychological needs for sustained health monitoring. The study also developed the five factors influencing the behavioural intention of adults to continue using gamification for sustained health monitoring. These factors are known as: broad appeal, applicability and accessibility through mobile technology and pervasive sensors, development and accomplishment, employment of creativity and feedback, and lastly social influence and relatedness. The recognition of weight loss, tracking and monitoring of physical activities and medication adherence was found to positively influence the behavioural intention of adults to continuosly use gamification to monitor their health. , Thesis (MCom) (Information Systems) -- University of Fort Hare, 2021

- Description: This thesis utilized a thematic content analysis, looked at how significant barriers affect Mashonaland Central girls and women living with disabilities as victims of crime from accessing justice. Zimbabwe is an optimal case to apply this study, due to its contradictory legislation and evidence of high rate of human rights violations. Mashonaland Central Province is an ideal case study due to the extant records that indicate that it has the highest incidences of violence against women. This study is therefore based in a Victimological epoch with the aim to fill the research gap in acknowledging the process of accessing justice as an important step for protecting and promoting human right. By analyzing interviews conducted with 3 different women aged 18-65 and 3 girls living with disability who were under the age of 18, through the theoretical framework of basic human rights theory and victim dynamics, this thesis contributes to the existing body of knowledge, with suggestions of how these barriers which are inclusive of societal and cultural structures tend to affect the respondents’ everyday lives and in a most pertinent manner towards their right to access justice. This thesis is also governed by the perspectives of key actors in the judicial process including but not limited to the Victim Friendly Unit. The theoretical framework is also operationalized into themes and criteria, which are then applied to analyze the conducted interviews. The emerging findings illuminate that there is a discrepancy between government policy surrounding girls and women living with disabilities and the practical experiences of the respondents. The respondents experienced a lack of accessibility to basic rights such as health care, the law, and to sex education – which are all rights ensured by government policy. Identified consequences included: discouragement in seeking justice due to fears of cultural and social stigma, discouragement in reporting crimes, and receiving adequate support, as well as information from secondhand sources. This study therefore concludes lack of access to justice is a violation of security of person, human dignity and rights to health and life to women and girls living with disability. , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2021

- Description: Female Genital Mutilation (FGM) is still rampant in many Kenya communities, especially the Maa and the Pokot speaking people, despite communication strategies and programmes instituted to eradicate the cultural practice. Female Genital Mutilation is a procedure that intentionally alters or cause injury to the female genital organs for non-medical reasons. The gains of eliminating FGM resulted from robust communication strategies introduced by the United Nations and the Kenyan government to educate and raise consciousness regarding the dangers of FGM practice. However, despite widespread communication efforts worldwide, at least thirty-one countries are still practising FGM. West Pokot County in Kenya has an 86% rate as a county that still practices FGM. The statistics are an indication that communication alone cannot achieve the desired goal as long as the communities feel that these organizations and their communication expects are looking down upon their culture, beliefs and practices. As far as FGM is concerned, attitude change is vital in communities to understand the dangers. Members of communities are often left behind or not consulted when developing strategies for eradicating FGM. Emphasis should be drawn on the involvement and ownership of such development programmes. Lack of participation from the communities seems to be the key reason for the failure of the campaigns to encourage people into deserting FGM practices. Therefore, this study evaluated communication strategies and explanations of why there is still a high level of FGM practice regardless of the prevalent consciousness of the consequences of its continued practice in West Pokot County, Kenya. This study adopts a mixed methodology (qualitative and quantitative) research approach. Convenience and purposive non-probability sampling techniques were subsequently used to select samples for this study. In-depth interviews and focus group discussions were held with the different community members in West Pokot County. There were five focus groups with nine participants in each focus group, making 45 participants for the focus group discussions. The collected data were interpreted and analysed thematically. This research showed a remarkable disparity between the community members ranging from their opinion and perceptions on the best and effective modes of communication to eradicate female genital mutilation and an alternative rite of passage. Another critical finding of this study indicated that beads of bondage linked to the community sanctioned rite of passage are another traditional practice that is endangering the lives of the girl child in Lokornoi, West Pokot County. Hence, this study proposed using mass media (newspapers, radio, television) using their vernacular language, which they understand and other interpersonal communication strategies (elders, chiefs and religious leaders) to eradicate FGM. Also, communication groups can involve communities to encourage a sense of ownership, which was the biggest reason for the communities to resist leaving FGM practice. This research suggests a need to develop alternative ways of communicating the message and that interpersonal channels are necessary to eradicate FGM in Kenya. , Thesis (MSoc Sci) (Communication) -- University of Fort Hare, 2021

- Description: The study aimed at investigating the management of students’ residential records at University of Fort Hare (UFH) and Rhodes University (RU). The objectives of the study were to: Investigate the residential policies and records management policies of the University of Fort Hare and Rhodes University; Assess the records management practices at the University of Fort Hare and Rhodes University; Determine how records management affects the process of allocating accommodation to students at the University of Fort Hare and Rhodes University; Identify areas of possible improvement of records management and student satisfaction concerning accommodation and allocation in both institutions. To achieve these objectives, the study used both qualitative and quantitative research methodologies. The data were collected using self-administered questionnaires and face-to-face interviews. A purposive non-probability sampling technique was used to select the participants of the study. Out of the targeted sample size of 39, the researcher administered questionnaires to 29 respondents and only 28 questionnaires were returned while 10 participants were interviewed. Therefore, a total of 38 staff members were included in the study. The qualitative data collected was analysed using thematic analysis while quantitative data collected was analysed using descriptive statistical analysis. The findings of the study showed that UFH and Rhodes University mostly make use of capturing process as one of the essential processes of records keeping used to allocate accommodation to students in their institutions. More importantly, the findings also revealed that there are different challenges faced by both universities. One of the challenges hindering student residence records at the University of Fort Hare (UFH) includes a lack of records xv management knowledge and incompetence. This might be because there are no records management personnel to take responsibility for student records. On the other hand, Rhodes University is faced with the unavailability of information sources, which might be attributed to a lack of information technology. , Thesis (MLIS) -- Faculty of Social Sciences and Humanities, 2021

- Description: Maize is the most essential cereal crop grown in Zimbabwe. This crop is produced across the country under different conditions and environments. The study focused on analyzing technical efficiency of A1 smallholder maize farmers in Chegutu and Zvimba districts under the Command Agriculture Scheme. Understanding technical efficiency is essential under developing agriculture, especially where resources are limited, and high population growth is quite common. In such a setting, increased output depends on efficiency improvements. The specific objectives of the study focused on estimating the level of technical efficiency, determinants of technical efficiency and the level of productivity among a randomly selected sample of 240 A1 smallholder maize farmers under the Command Agriculture Scheme. Purposive, cluster and random sampling techniques were used to collect primary data from the selected sample. The study applied the single-stage modelling stochastic frontier approach to assess technical efficiency of A1 smallholder maize farmers. The stochastic frontier results revealed that A1 smallholder farmers in Chegutu and Zvimba districts are technically efficient at 85 percent and 94 percent, respectively. The major determinants of technical efficiency varied across each district. In Chegutu district, major determinants of technical efficiency were basal fertilizer, labour and area of land cultivated for maize production, and all indicated a positive relationship with level of significance less than 10 percent and 1 percent (0.012, 0.000 and 0.000) respectively. In Zvimba district, major determinants of technical efficiency were basal fertilizer, topdressing and area of land cultivated for maize production, and all indicated a positive relationship with level of significance less than 5 percent, 10 percent and 1 percent (0.002, 0.021, 0.000) respectively. The study further estimated determinants of technical inefficiency. Main determinants of technical inefficiency in Chegutu district were age, maize farming experience and level of education. In Zvimba district, main determinants were maize farming experience, level of education, marital status, occupation status and other sources of income. The return to scale that measures the productivity level of farmers varied among the two districts in which farmers from Chegutu district had increasing returns to scale (1.43), whilst famers from Zvimba district had decreasing returns to scale (0.54). The study, therefore, argues that despite observed high technical efficiencies, Chegutu farmers could bridge their 15 percent gap between their observed output and the frontier output by focusing more on input usage with increasing returns to scale (1.43 percent). On the other hand, Zvimba farmers could bridge their 6 percent gap between their observed output and frontier output by focusing more on socio-economic drivers of technical inefficiency, given the decreasing returns to scale of their inputs (0.54 percent). , Thesis (MSc) (Agricultural Economics) -- University of Fort Hare, 2021

- Description: The purpose of the study was to scrutinise and assess the effects of South African school’s rationalization framework on educator morale in the Eastern Cape Department of Basic Education amidst the research objectives. The researcher wanted to establish if the Department of Education had succeeded in the implementation of the policy. In terms of the accomplishment of the objectives the researcher wanted to determine whether the exercise of the policy had affected the morale of educators. The study reviewed the literature, theoretical and empirical assessment of rationalisation process on the morale of educators in the King William’s Town district in the Eastern Cape. The study adopted a case study design of qualitative approach. The target population of the study included seventeen educators of the five schools in King William’s Town. A purposive sampling was used to select the respondents. A semi – structured interviews and questionnaires was used, and data was analysed using thematic approach according to the themes from the research questions. The questionnaire method succeeded by interviews was used for the collection of data. The tables and bar graphs were used to represent the number of respondents that participated in the study.

- Description: The purpose of the study was to scrutinise and assess the effects of South African school’s rationalization framework on educator morale in the Eastern Cape Department of Basic Education amidst the research objectives. The researcher wanted to establish if the Department of Education had succeeded in the implementation of the policy. In terms of the accomplishment of the objectives the researcher wanted to determine whether the exercise of the policy had affected the morale of educators. The study reviewed the literature, theoretical and empirical assessment of rationalisation process on the morale of educators in the King William’s Town district in the Eastern Cape. The study adopted a case study design of qualitative approach. The target population of the study included seventeen educators of the five schools in King William’s Town. A purposive sampling was used to select the respondents. A semi – structured interviews and questionnaires was used, and data was analysed using thematic approach according to the themes from the research questions. The questionnaire method succeeded by interviews was used for the collection of data. The tables and bar graphs were used to represent the number of respondents that participated in the study. The findings denoted that some of the educators believed the Department of Education had not planned the process of rationalisation sufficiently as it brought about anxiety and stress, though some of the affected educators mentioned that it brought relief as there are additional educators to teach other learning areas. The study recommended that the Department of basic Education in Eastern Cape should as a matter of priority provide maximum support to the affected educators. The study concluded that it became evident that the interaction with the respondents showed that the rationalisation process affects redeployed educators negatively.

- Description: The neoclassical theory suggests that free flow of external capital should be equilibrating and thereby facilitating smoothening of an economy's consumption or production patterns. Based on this background, this study empirically examines the extent to which the different forms of capital flows amongst other variables influence the real exchange rate in South Africa for the period 1980 to 2019, using annual data. Estimation techniques employed include the Johansen Co-integration Approach and the Vector error correction model (VECM). The variables were found to be co-integrated, with six co-integrating vectors existing. The long-run results revealed that FPI has an appreciating effect on the exchange rate in South Africa. Based on the results, policy recommendations are suggested. , Thesis (MCom) (Economics) -- University of Fort Hare, 2021.

- Description: The objective of this study was to determine the chemical composition and in vitro ruminal dry matter degradation (DMD) of Vachellia karro leaf meal-containing diets and their effect on feed intake and physiological responses of indigenous Xhosa lop-eared goats. Experimental diets containing 0 percent (Treatment 1), 15 percent (Treatment 2) and 30 percent (Treatment 3) Vachellia karroo leaf meal were mixed with grass hay and crushed maize. Samples of each diet were analysed for chemical composition and in vitro ruminal DM degradability. A total of 18 eight-month-old indigenous Xhosa lop-eared goats, initially weighing 20.81 ± 1.83 kg were randomly assigned to each diet in a Completely Randomized Design. The goats were confined in individual well-ventilated roofed pens and each dietary treatment had a total of 6 goats. The feed was offered at a rate of 3 percent of live weight twice a day, at 08:00 in the morning and at 16:00 in the afternoon. The experimental feeding trial lasted for 80 days, where 10 days was allowed for adaptation. Goat live weight, Average daily feed intake (ADFI), and Body condition scores (BCS) were recorded weekly FAMACHA scores and fecal eggs counts were also determined weekly. Blood samples were collected via vein puncture on the last day of the feeding trial for determination of glucose, total cholesterol, albumin and blood urea. Significantly higher (P < 0.05) crude protein (CP) and condensed tannins (CT) levels were observed in Vachellia karroo containing diets., while acid detergent fibre (ADF) and neutral detergent fibre (NDF) were significantly higher (P < 0.05) in the control diet. During early hours of incubation, DMD was similar (P > 0.05) across all dietary treatments. At 12 to 72 hours, the DMD was significantly higher (P < 0.05) in Vachellia karroo containing diets except at 48 hours. Correlation between DMD and NDF, ADF and fat was only visible at 24 hours. Fibre (ADF and NDF) were negatively related to DMD, while fat was positively related. A positive correlation was observed between DMD and DM, CP and ADFI. The body weight and BCS of goats was similar (P > 0.05) in all dietary treatments (P > 0.05). The ADFI was significantly higher (P < 0.05) in Vachellia karroo supplemented goats. Faecal egg count and FAMACHA scores were significantly higher (P< 0.05) in the control group compared to the Vachellia karroo supplemented treatments; while glucose levels were significantly higher in goats supplemented with Vachellia karroo compared to non-supplemented goats. Cholesterol levels were similar (P > 0.05) across all experimental groups. Goats consuming 30 percent of Vachellia karroo leaf meal had higher (P < 0.05) creatinine levels than the non-supplemented treatment. Urea levels were significantly higher (P < 0.05) in goats fed 30 percent of Vachellia karroo leaf meal than other treatments. It was concluded that the inclusion of Vachellia karroo leaves improves diet quality, diet degradability, average daily feed intake and physiological responses. , Thesis (MSc) (Animal Science) -- University of Fort Hare, 2021

- Description: Fruits are key contributors to human nutrition and health. However, banana and plantain are typical examples of fruits that have nutritionally under-utilized peel by-products. This study was thus carried out to investigate the compartmental distribution (soft flesh, peel, and boiled peel extract) of mineral elements, nutritional factors, biological potentials, and phytochemical profiles in M. sinensis and M. paradisiaca fruits (ripening stage 4-5), with focus on the peels. Proximal and and antinutritive analyses were done with standard methods of the Association of Official Analytical Chemists (AOAC), while mineral element composition in the fruit components was analyzed with the inductively coupled plasma optical emission spectroscopy (ICP-OES). The pharmacological potential of M. sinensis and M. paradisiaca fruit components was investigated spectrophotometrically by evaluating the polyphenolic constituents (total phenol, proanthocyanidin, flavonoid) and in vitro radical scavenging activities of the aqueous, acetone and ethanol extracts, using DPPH, ABTS, and FRAP assay models. The correlational evaluation of the polyphenolics and antioxidant activity in the components of both fruits using Pearson’s correlational coefficient (r). The proximal assays revealed that moisture content, fiber content, and carbohydratecontent were substantially present in the flesh and peel of M. sinensis and M. paradisiaca, while lipid content was low. The antinutritive results revealed safe levels of alkaloid, oxalate, phytate, and saponin factors in the flesh and peel by-products. Mineral analysis results indicated substantial levels of the macroelements K, Mg, Ca, and P in the peels. Other results revealed that acetone extracts had the highest phenolic, proanthocyanidin and flavonoid constituents respectively, across the soft flesh components ofM. sinensis (119.05 ± 5.80 mgGAE/g; 337.48 ± 13.16 mgCE/g; 602.64 ± 3.65 mgQE/g), M. paradisiaca (114.80 ± 1.49 mgGAE/g; 436.09 ± 36.44 mgCE/g; 777.35 ± 150.95mgQE/g) and the peel component of M. paradisiaca (136.87 ± 5.69 mgGAE/g; 530.06 ± 53.51 mgCE/g; 750.87 ± 55.61 mgQE/g), with an exception of the phenolic content of M. sinensis peel, where it was highest in the ethanol extract (157.19 ± 4.76 mgGAE/g). The ABTS (0.03 mg/mL) and DPPH (0.03 mg/mL) activities were at their highest in the boiled peel extracts of M. sinensis and M. paradisiaca, while ferric reducing power was highest in ethanol extracts across M. sinensis soft flesh, peel, and M. paradisiaca flesh. Acetone extract of M. paradisiaca peel had the highest ferric reducing capacity at peak concentration (0.1 mg/mL). Correlational analysis revealed a negative correlation between respective phenolic, proanthocyanidin, and flavonoid content and the IC50DPPH antioxidant capacity in M. sinensis flesh, M. sinensis peel and M. paradisiaca flesh. Conversely, there was positive correlation between IC50 DPPH with proanthocyanidin and flavonoid in M. paradisiaca peel. Negative correlation was detected between the phenolic, proanthocyanidin and flavonoid contents and IC50ABTS in M. sinensis flesh. Positive correlation was observed between respective phenolic, proanthocyanidin and flavonoid contentwith IC50 ABTS in M. sinensis peel, M. paradisiaca flesh and M. paradisiaca peel. There was negative correlation between the respective phenolic, proanthocyanidin and flavonoid contents and IC50 FRAP in the flesh of M. sinensis, while positive correlation was observed in M. sinensis peel. M. paradisiaca flesh on the other hand, showed positive correlation between the IC50 FRAP and the respective phytochemical contents. However, the peel, there was negative correlation. The correlational evaluation in this study revealed general positive and negative correlational patterns, which implies that no polyphenolic constituent contributed exclusively to antioxidant activity, but rather in combination. Ultrastructure and elemental spectra of M. sinensis and M. paradisiaca exocarps were analysed with electron microscopy (SEM)and energy dispersive x-ray (EDX). Microstructures such as interlocked, polyhedral epidermal cells, ellipsoid-shaped stomata, guard cells, intercellular space, anticlinal-patterned walls, and subsidiary cells were observed. The elemental spectra revealed the presence of elements such as potassium, iron, carbon, oxygen, silicon, and gold, with consistently high to relatively high carbon and oxygen peaks in M. sinensis and M. paradisiaca exocarps. The relative similarity observed in the constituents of a number of the elemental spectra in M. sinensis and M. paradisiaca peels, reflects some degree of relatedness. These outcomes indicate that banana and plantain peel and boiled peel extracts are nutritive, medicinal and potential nutraceuticals, with food preservative, shelf-life and quality enhancement potentials. The instrumentation in this study also have potential relevance in industrial food product analysis. , Thesis (PhD) -- Faculty of Science and Agriculture, 2021

- Description: With the exponential rise in conflict scenarios globally, the number of internally displaced persons (IDPs) and refugees in foreign countries continues to grow. Although there has been several international efforts and conventions aimed at alleviating the global refugee crisis, the international community has not found a sustainable answer to this knotty problem. In Africa, with some of the worst conflict situations, the scourge of social displacement resulting in migrations have caused different levels of risks and vulnerability for the refugees, as well as capacity constraints for the host communities, governments of host countries and non-governmental bodies working with refugees. In South Africa, with one of the highest numbers of refugees in Africa, especially those coming from African countries, contention for socio-economic space and cultural differences occasionally result in violence between refugees and local people. For the older refugees, the level of risk exposure and hardship have generated interests for both scholars and officials. This thesis explores the risks and support systems for older refugees in South Africa, with specific focus on the Eastern Cape province. Various stakeholders (such as government, NGOs, host communities and the older refugees) in refugee management in South Africa have argued differently on ‘how best’ to manage older refugees in the country. Using qualitative data gathered from refugee communities in the Eastern Cape province and documentary analysis, the study found that the experiences of older refugees in the Eastern Cape province are nuanced. The dominant narrative on the experiences of older refugees indicate peaceful coexistence and resilient organic community support systems, with minor conflicts – often associated with contestations for scarce economic opportunities. Although the study focuses on one province of South Africa, this finding challenges the often-overgeneralised perception of South Africa as ‘xenophobic’. It unpacks the hidden resilient social systems and networks of relationships that bind local populations and the refugees, especially the older ones. In the search for national, regional and global answers on the best way to manage refugee crisis, this study provides insights into community-level structures and dynamics that would benefit policymaking at the national and international levels , Thesis (PhD) -- Faculty of Social Sciences and Humanities, 2021

- Description: Cattle industry improves livelihoods for many developing farmers in South Africa, however, ticks and tick-borne diseases (TBDs) pose a detriment impact on cattle success; this is due to their resistance to acaricide application. Thus, this study was conducted to determine the extent of acaricide resistance, serostatus of tick-borne pathogens, and geographic range of boophilid ticks in communal grazing cattle in the north-eastern regions of the Eastern Cape Province (ECP), South Africa. A total of 160 structured questionnaires were prepared and randomly administered to cattle farmers to investigate their knowledge, attitudes, and practice on ticks and TBDs affecting cattle, tick control methods used, and their knowledge of acaricide resistance. Engorged visible cattle ticks were collected seasonally from 10 randomly selected cattle from the community cattle herds during dipping days between October 2018 and September 2019, and stored into the labelled test tubes containing 70 percent ethanol. For TBDs determination, a total of 240 cattle from Elundini and Senqu Municipalities were seasonally used to investigate the prevalence of ticks and TBDs, packed cell volume (PCV), and body condition scores (BCS). Shaw Larval Immersion Test (SLIT) method was used to determine the resistance of Rhipicephalus decoloratus larvae to various acaricides such as amidines, organophosphate, and synthetic pyrethroids. This study indicates that approximately 59 percent of the interviewed cattle farmers had no knowledge of the effect of TBDs affecting cattle production, and 78 percent of respondents considered ticks are the major challenge to the success of their cattle farming. Pour-on (61 percent) was the most commonly used acaricidal treatment system with fortnightly (40 percent and 31percent) treatment frequencies during the summer and winter seasons respectively. Synthetic pyrethroids (73 percent) were the most used acaricide compounds to control ticks. Moreover, approximately 85 percent of respondents perceived that they do not practice acaricide rotation, and 88 percent of the respondents had no knowledge of acaricide resistance. Interestingly, the current study record Rhipicephalus microplus for the first time at Elundini, Senqu, and Walter Sisulu. Based on the morphological traits, a total of 6176 ticks belonging to two boophilid tick species of Rhipicephalus were identified: R. decoloratus (98 percent) and R. microplus (2 percent). Rhipicephalus decoloratus was significantly higher (P<0.05) in Elundini during the hot-dry (3.37±0.121) and hot-wet (3.35±0.121) seasons compared to other localit ies. In Senqu, R. microplus had high counts (P<0.05) during the post-rainy season (1.06±0.027) compared to other localities. From this present study, it was observed that Ehrlichia ruminantium was the most prevalent at Elundini (16 percent) and (14 percent) during post-rainy and hot-dry seasons respectively and 15 percent at Senqu during the post-rainy season. Babesia bigemina was more frequent at Elundini (18 percent) and Senqu (16 percent) during the post-rainy season and hot-wet season, respectively. Cattle BCS were significantly negatively correlated with E. ruminantium (P<0.01; r = -0.203), B. bovis (P<0.01; r = -0.125), and A. marginale (P < 0.01; r = -0.122). On the other hand, PCV was significantly negatively correlated with B. bigemina (P<0.01; r =-0.138). E. ruminantium was strongly positively correlated with Amblyomma hebraeum (P<0.05; r = 0.112), while B. bovis (P<0.05; r = 0.134) and B. bigemina (P<0.05; r = 0.188) were strong positively correlated with Rhipicephalus microplus infestation and B. bigemina (P<0.05; r = 0.077) with Rhipicephalus decoloratus. During acaricide resistance testing, Shaw Larvae Immersion Testing (SLIT) was only performed on R. decoloratus larvae as engorged R. microplus ticks could not meet the required sample size for resistance testing. The current study found that the majority of the tick were susceptible at exposure to differe nt acaricide field concentrations of amidines (49 percent at 250ppm), organophosphates (33 percent and 47 percent at 300ppm and 500ppm, respectively), and synthetic pyrethroids (44 percent and 23 percent at 150ppm and 300ppm, respectively). In conclusion, less knowledge of cattle farmers on the threat pose by ticks on their cattle production results in the spatio-temporal spread of boophilid tick from region to region and from season to season thus increases incidence and risk for tick resistance. , Thesis (PhD) -- Faculty of Science and Agriculture, 2021

- Description: Cattle industry improves livelihoods for many developing farmers in South Africa, however, ticks and tick-borne diseases (TBDs) pose a detriment impact on cattle success; this is due to their resistance to acaricide application. Thus, this study was conducted to determine the extent of acaricide resistance, serostatus of tick-borne pathogens, and geographic range of boophilid ticks in communal grazing cattle in the north-eastern regions of the Eastern Cape Province (ECP), South Africa. A total of 160 structured questionnaires were prepared and randomly administered to cattle farmers to investigate their knowledge, attitudes, and practice on ticks and TBDs affecting cattle, tick control methods used, and their knowledge of acaricide resistance. Engorged visible cattle ticks were collected seasonally from 10 randomly selected cattle from the community cattle herds during dipping days between October 2018 and September 2019, and stored into the labelled test tubes containing 70 percent ethanol. For TBDs determination, a total of 240 cattle from Elundini and Senqu Municipalities were seasonally used to investigate the prevalence of ticks and TBDs, packed cell volume (PCV), and body condition scores (BCS). Shaw Larval Immersion Test (SLIT) method was used to determine the resistance of Rhipicephalus decoloratus larvae to various acaricides such as amidines, organophosphate, and synthetic pyrethroids. This study indicates that approximately 59 percent of the interviewed cattle farmers had no knowledge of the effect of TBDs affecting cattle production, and 78 percent of respondents considered ticks are the major challenge to the success of their cattle farming. Pour-on (61 percent) was the most commonly used acaricidal treatment system with fortnightly (40 percent and 31percent) treatment frequencies during the summer and winter seasons respectively. Synthetic pyrethroids (73 percent) were the most used acaricide compounds to control ticks. Moreover, approximately 85 percent of respondents perceived that they do not practice acaricide rotation, and 88 percent of the respondents had no knowledge of acaricide resistance. Interestingly, the current study record Rhipicephalus microplus for the first time at Elundini, Senqu, and Walter Sisulu. Based on the morphological traits, a total of 6176 ticks belonging to two boophilid tick species of Rhipicephalus were identified: R. decoloratus (98 percent) and R. microplus (2 percent). Rhipicephalus decoloratus was significantly higher (P<0.05) in Elundini during the hot-dry (3.37±0.121) and hot-wet (3.35±0.121) seasons compared to other localit ies. In Senqu, R. microplus had high counts (P<0.05) during the post-rainy season (1.06±0.027) compared to other localities. From this present study, it was observed that Ehrlichia ruminantium was the most prevalent at Elundini (16 percent) and (14 percent) during post-rainy and hot-dry seasons respectively and 15 percent at Senqu during the post-rainy season. Babesia bigemina was more frequent at Elundini (18 percent) and Senqu (16 percent) during the post-rainy season and hot-wet season, respectively. Cattle BCS were significantly negatively correlated with E. ruminantium (P<0.01; r = -0.203), B. bovis (P<0.01; r = -0.125), and A. marginale (P < 0.01; r = -0.122). On the other hand, PCV was significantly negatively correlated with B. bigemina (P<0.01; r =-0.138). E. ruminantium was strongly positively correlated with Amblyomma hebraeum (P<0.05; r = 0.112), while B. bovis (P<0.05; r = 0.134) and B. bigemina (P<0.05; r = 0.188) were strong positively correlated with Rhipicephalus microplus infestation and B. bigemina (P<0.05; r = 0.077) with Rhipicephalus decoloratus.

- Description: The depletion of the environment compelled researchers to investigate Environmental Education issues, the methods of imparting knowledge and the creation of awareness about environmental problems. However, youths have knowledge of environmental concepts but lack the skills, intentions, and action competence to exhibit positive environmentally responsible behaviour. There is, therefore, a need for a change in human behaviour to overcome current environmental problems. This study determines the effect of an environmental responsible behaviour intervention programme on Junior Secondary School learners in environmental education. It also explores the moderating effects of gender and school location. The study adopted a pre-test, post-test, control group and quasi-experimental design. A multi-stage sampling technique was employed. Eight (8) coeducational secondary schools in Ibadan, Nigeria, were selected based on environmental challenges in their immediate environment. There were four (4) schools from Ibadan city (urban area of Ibadan) and four (4) from Ibadan less city (rural area of Ibadan). Seven hypotheses were tested at a 0.05 level of significance. Five research instruments were used for this study. Analysis of Covariance (ANCOVA) was used in testing the seven formulated hypotheses. Estimated Marginal mean analysis was used to determine the source of significant effect of treatment. A significant interaction effect was described using a graphical representation. All hypotheses were tested at P< .05 level of significance. The result reveals that there was a significant main effect of treatment (Environmental responsible behaviour intervention programme on Junior Secondary School learners’ environmental knowledge (F(1,715) = 40.62, p < 0.05, Partial , 2 .054). There was also significant main effect of treatment (environmental responsible behaviour intervention programme on junior secondary school students’ environmental attitude.

The effect of treatment (Environmental responsible behaviour intervention programme) on students’ environmental practices was statistically significant, F(1,715) = 17.02, p < 0.05. partial 2 = 0.023). The findings shows that there was a significant main effect of school location (Urban and Rural) on Junior Secondary School students’ environmental knowledge (F(1,716) = 71.62 p< 0.05. partial 2 =0.091). There was no significant main effect of gender (male / female) F(1,715) =0.27, p> 0.05, partial 2 = 0.000. The findings further shows that there was significant main effect of school location on students’ environmental attitude, (F(1,175) =39.21, p< 0.05 partial 2 = 0.052) Shows that there was no significant main effect of gender on students’ environmental attitude F(1,715) =2.1, p> 0.05. partial 2 =0.003 There was significant main effect of school location on students’ environmental practices, F(1,715) = 17.02, p< 0.05 partial 2 = 0.019 but there was no significant main effect of gender on students’ environmental practices, (F(1,715) = 1.17, p> 0.05. partial 2 = 0.002). Based on these findings, it is recommended that teachers should use an environmental responsible behaviour intervention programme in teaching environmental concepts in the classroom. To support this, group/teamwork should be encouraged amongst students. Students should be allowed to construct knowledge in order to bring about their active participation with a view to making learning realistic and effective and to enable the exhibition of environmentally friendly behaviour. , Thesis (PhD)(Education)-- University of Fort Hare, 2021

- Description: Beef breeds of cattle are predominantly raised through extensive grazing and produce the highest levels of enteric methane (CH4) through ruminal fermentation. The objective of this study was to evaluate the effect of breed, grazing, and age on enteric methane production and performance of beef cows as well as effect of breed and grazing system on ruminal fermentation parameters. Two separate studies were conducted; the first study evaluated the effect of grazing system, breed, and age on ruminal enteric methane production and performance of selected beef breeds. The second study evaluated the effect of the grazing system and breed on ruminal fermentation. In the first study, two breeds (Nguni and Bonsmara) raised under two grazing systems (communal and commercial) in a random complete block design were grouped into 3 age categories. Eighty-four cows aged between 24-120 months were randomly selected and grouped by age: group A (young adult cow, n = 7, 24-48 months old), group B (adult, n = 7, 60-80 months old), and group C (old adult, n = 7, 90-120 months) in either grazing system. Data were collected on methane production per day, body condition, and weight used to estimate dry matter intake (DMI), methane per DMI, and methane per body weight. In the second study, 40 cows of the same age group, parity, and physiological status were used. Ten cows per breed (Bonsmara and Nguni) in either grazing system (communal and commercial) were used in a random complete block design. Rumen fluid collection was done by the stomach tube method. Data were collected on ruminal ammonia-nitrogen (NH3-N), pH, Temperature, volatile fatty acids (VFAs). Older animals produced higher methane per head in the order of C > B > A; (P<0.0001). Performance parameters like Body condition score (BCS), body weight (BW), dry matter intake (DMI), and daily methane were higher (P<0.05) in Bonsmara. However, Methane per BW was higher in Nguni (P<0.05), and methane per DMI did not differ among breeds (P>0.05). Body condition, BW, and DMI were higher (P<0.05) in commercial grazing system. Contrary, daily methane production, methane production per DMI, and methane produced per BW were higher in communal grazing. In the second study, Ruminal NH3-N concentration ranged between 69.05 - 96.78 mg/L and was higher (P<0.05) in Nguni. It was also higher (P<0.05) in the commercial grazing system. Ruminal pH, temperature, total VFAs, and certain individual VFAs (iso-butyrate, valeric and iso-valeric) did not differ (P>0.05) among breeds and grazing systems. However, total VFAs were slightly lower in communal grazing (78.87 mmol/L) than commercial grazing (89.80 mmol/L). Acetate, propionate, butyrate proportions, and acetate to propionate ratio did not differ (P>0.05) among breeds but differed (P<0.05) between grazing systems. Acetate (P<0.05) and acetate to propionate ratio (P<0.05) were higher in the communal grazing system, while the reverse was true for propionate (P<0.05) and butyrate (P<0.05). Bonsmara produced more methane than Nguni under similar conditions, with Nguni uniquely producing more methane per BW, indicating host genetics influence. Communal animals and older animals produced more CH4 than commercial and younger cows regardless of the breed, indicating ruminal inefficiencies in very old cows. These results emphasize the idea that host genetics or breed, grazing system, and age influence methane output and performance. Hence, breeding strategies for hard-to-measure traits like methane production need to put all these factors into consideration. , Thesis (MSc) (Animal Science) -- University of Fort Hare, 2021

- Description: The continuous outpour of aromatic pollutants in diverse groups, emanating from the industrial and domestic system due to population density, industrialisation and technological advancement is alarming. The increasing strength in wastewater discharge constitutes the main cause of the natural water pollution load, causing scarcity of potable water for consumption with an increasing health challenge. The physiochemical treatment approach has faced a series of limitations with little or no success. Hindrance to wastewater management can cause a point source contamination problem that might increase treatment cost and release a broad range of chemical contaminants in the environment. Hence, green, eco-friendly and cost-effective tools are imperative. The application of laccase has received much attention in bioremediation and bioprocessing matters owing to the oxidising capacity of a wide range of substrates. The process requires available molecular oxygen for its activation, releasing water as a by-product thus, establishing this research. This study was devised to examine the bioprocessing potentials of hybrid and amalgamated laccases extracted from the diverse environmental milieu of the Eastern Cape Province, South Africa. Bacteria producing laccase were isolated from marine sediment, cow dung, and wastewater samples via selective enrichment with some aromatic compounds. The axenic cultures were screened for laccase activity on various phenolic and non-phenolic substrates. The isolates were identified via molecular techniques and they belonged to the gammaproteobacteria and Bacilli classes under the following genera, Enterobacter and Bacillus. They were deposited in the NCBI database as Enterobacter asburiae ES1, Enterobacter sp. Kamsi, Enterobacter sp. AI1, and Bacillus sp. NU2 with the assigned accession number MN686602, MN686603, MN686605, MN686607, respectively. Optimisation of the laccase production via one factor at a time technique (OFAT) from the four bacteria species showed more enzyme yield in all lignocellulosic agro-waste media. However, wheat bran and mandarin peel maximally enhanced laccase production. In addition, xylose, galactose, fructose, and sorbitol were the best carbon sources utilised while (NH₄)₂SO8, KNO3 and NaNO3 were noted as the best nitrogen sources employed. Laccase yields were increased at pH 4 and 5, at temperatures 45 and 55 o C, and at 50 and 100 rpm, and precisely, at day eight of the incubation period. Further purification of the crude laccase yielded a purification fold of 4.18, 4.39, 2.78, 8.11, and the SDS-PAGE analysis showed a molecular size of 90, 55, 75 and 50 kDa for ES1, Kamsi, AI1, and NU2 laccases, respectively. The characterised purified laccase demonstrated polyextremotolerant potentials. The laccases were active through a wide temperature regime (30-90 o C) with maximum activity at 50 o C (ES1/AI1 and Kamsi/NU2) 60 o C (AI1), 70 o C (ES1, Kamsi, NU2); and were stable at 60 o C (ES1, AI1, NU2), 70 o C (ES1/AI1), 80 o C (Kamsi and Kamsi/NU2). Also, the laccases remained active through pH 3 - 8 and optimal at pH 4 (AI1, NU2), pH 5 (Kamsi, ES1/AI1), pH 7 (ES1), pH 8 (Kamsi/NU2), and the individual stability was measured at pH 4 (Kamsi, NU2), pH 5 (AI1), pH 6 (ES1), pH 7 (Kamsi/NU2), pH 10 (ES1/AI1). The purified laccases were either enhanced or left unchanged by a variable concentration of metallic salts, inhibitors, chelating agents and organic solvents. Clearly, the activities of the laccase were enhanced when pre-incubated with 1, 3, and 6 mm of CuCl2, FeCl3, MgCl2, ZnCl2 and AgCl, and 1, 2, 3 mm of Triton x-100, PMSF, EDTA, Tween 20, and NaCl. Additionally, 20, 30, and 10 percent v/v of acetone and DMSO were prominent organic solvents that also stimulated both the hybrid and amalgamated laccase activity. The gene of the purified laccases targeted showed a clear band size of 690 bp for the Enterobacter species laccases and 775 bp for the laccase from Bacillus sp. The protein sequence was deposited in NCBI database with the assigned accession numbers, MW251989, MW25990, MW251992, and MW251994 for ES1, Kamsi, AI1, and NU2 laccases, respectively. The optimised pH and temperature parameter examined on the decolourising potential of the bacteria laccases showed an effective dye removal on the five synthetic dyes (Congo Red (CR), Methyl Orange (MO), Malachite Green (MG), Reactive Blue 4 (RB4), Ramazol Brilliant Blue R (RBBR)) applied. The purified laccases were successfully immobilised in Na-alginate with cca. 88.49, 70.91, 76.04, 76.13, 90.07, and 91.99 laccase yield for the hybrid (ES1, ES1, Kamsi, AI1, NU2) and amalgamated (ES1/AI1 and Kamsi/NU2) laccases. The immobilised laccases were able to retain an average activity of 32 – 52 percent after eight dye decolourising cycles, exhibiting strong catalytic activity than the free laccases. Nonetheless, no significant difference was examined between the hybrid and amalgamated laccase activity. Also, the immobilised laccases were shown to be more efficient in biotechnological application than the free laccases. The result suggests that immobilising an enzyme in a carrier matrix served effectively as the remediation approach than the hybrid and the amalgamation of the free enzymes. Also, the application of lignocellulosic waste served as a cheaper substrate for commercial production of laccase and could help s in promoting es the biotechnology application and the bioeconomy. , Thesis (PhD) -- Faculty of Science and Agriculture, 2021

In addition, xylose, galactose, fructose, and sorbitol were the best carbon sources utilised while (NH₄)₂SO8, KNO3 and NaNO3 were noted as the best nitrogen sources employed. Laccase yields were increased at pH 4 and 5, at temperatures 45 and 55 o C, and at 50 and 100 rpm, and precisely, at day eight of the incubation period. Further purification of the crude laccase yielded a purification fold of 4.18, 4.39, 2.78, 8.11, and the SDS-PAGE analysis showed a molecular size of 90, 55, 75 and 50 kDa for ES1, Kamsi, AI1, and NU2 laccases, respectively. The characterised purified laccase demonstrated polyextremotolerant potentials. The laccases were active through a wide temperature regime (30-90 o C) with maximum activity at 50 o C (ES1/AI1 and Kamsi/NU2) 60 o C (AI1), 70 o C (ES1, Kamsi, NU2); and were stable at 60 o C (ES1, AI1, NU2), 70 o C (ES1/AI1), 80 o C (Kamsi and Kamsi/NU2). Also, the laccases remained active through pH 3 - 8 and optimal at pH 4 (AI1, NU2), pH 5 (Kamsi, ES1/AI1), pH 7 (ES1), pH 8 (Kamsi/NU2), and the individual stability was measured at pH 4 (Kamsi, NU2), pH 5 (AI1), pH 6 (ES1), pH 7 (Kamsi/NU2), pH 10 (ES1/AI1). The purified laccases were either enhanced or left unchanged by a variable concentration of metallic salts, inhibitors, chelating agents and organic solvents. Clearly, the activities of the laccase were enhanced when pre-incubated with 1, 3, and 6 mm of CuCl2, FeCl3, MgCl2, ZnCl2 and AgCl, and 1, 2, 3 mm of Triton x-100, PMSF, EDTA, Tween 20, and NaCl. Additionally, 20, 30, and 10 percent v/v of acetone and DMSO were prominent organic solvents that also stimulated both the hybrid and amalgamated laccase activity. The gene of the purified laccases targeted showed a clear band size of 690 bp for the Enterobacter species laccases and 775 bp for the laccase from Bacillus sp. The protein sequence was deposited in NCBI database with the assigned accession numbers, MW251989, MW25990, MW251992, and MW251994 for ES1, Kamsi, AI1, and NU2 laccases, respectively. The optimised pH and temperature parameter examined on the decolourising potential of the bacteria laccases showed an effective dye removal on the five synthetic dyes (Congo Red (CR), Methyl Orange (MO), Malachite Green (MG), Reactive Blue 4 (RB4), Ramazol Brilliant Blue R (RBBR)) applied. The purified laccases were successfully immobilised in Na-alginate with cca. 88.49, 70.91, 76.04, 76.13, 90.07, and 91.99 laccase yield for the hybrid (ES1, ES1, Kamsi, AI1, NU2) and amalgamated (ES1/AI1 and Kamsi/NU2) laccases. The immobilised laccases were able to retain an average activity of 32 – 52 percent after eight dye decolourising cycles, exhibiting strong catalytic activity than the free laccases. Nonetheless, no significant difference was examined between the hybrid and amalgamated laccase activity. Also, the immobilised laccases were shown to be more efficient in biotechnological application than the free laccases. The result suggests that immobilising an enzyme in a carrier matrix served effectively as the remediation approach than the hybrid and the amalgamation of the free enzymes. Also, the application of lignocellulosic waste served as a cheaper substrate for commercial production of laccase and could help s in promoting es the biotechnology application and the bioeconomy. , Thesis (PhD) -- Faculty of Science and Agriculture, 2021

- Description: Boophone disticha (L.f.) Herb. is a bulbous plant native to southern African areas of the continent and spreads to tropical Africa. The plant has been noted in literature for its high toxicity and has a long lineage of its use in traditional medicine for the treatment of various diseases. Due to high demand in the conventional trade market, the plant's conservation status has been shown to be declining. The plant has been reported to cause human poisoning, which can lead to death, but the plant is still administered by an indigenous community to treat various diseases. This study investigated the therapeutic potential of B. disticha used by the people of Raymond Mhlaba municipality to show and verify its use in traditional medicine and how it can be used as a possible drug ingredient. This study was also set out to investigate the anti-mycobacterial activity of the plant for the first time for the B. disticha growing in the Eastern Cape region of South Africa. The phytochemical analysis of B. disticha was carried out on four different plant parts (i.e., roots, leaves, bulb inner and outer scales) and the plant was extracted using methanol and distilled water. The qualitative phytochemical analysis displayed the presence of tannins, flavonoids, phenols and alkaloids in all plant parts for both extraction solvents. Anthraquinones were absent in all the plant extracts. The detected phytochemicals (tannins, flavonoids, phenols and alkaloids) were quantified. The roots had the highest phytochemical content for methanol extract for each phytochemical tested [439.67±1.53 mg/g (QE) flavonoids, 2414.67±1.53 mg/g (GAE) phenols and 527.33±2.08 mg/g (GAE) alkaloids] compared to all the plant parts. Methanol extracts from B. disticha revealed highest phenolic contents (2414.67±1.53 mg/g GAE) for the roots, 1395.33±2.52 mg/g (GAE) for the bulb inner scales, 1560±1 mg/g (GAE) for the leaves and 1550.7±18.9 mg/g (GAE) for the bulb outer scales). The total flavonoid content of the bulb outer scales aqueous extract was not detected. The presence of significant amounts of phytochemical compounds indicates that B. disticha has a higher medicinal value and can be extensively investigated to extract bioactive ingredients that are useful to the society, and that could be sold for higher production than using synthetic drugs with side effects. The antimicrobial activity of B. disticha extracts (methanol and distilled water) was evaluated using micro-dilution bioassay in 96-well micro-plates against nine disease-causing bacterial strains (5 Gram-negative and 4 Gram-positive) and three fungal isolates. The results revealed that methanol and aqueous extract of B. disticha demonstrated very good activity, with Gram-positive strains being more sensitive than Gram-negative ones. Boophone disticha aqueous extracts displayed the best activity against Staphylococcus aureus with MIC and MBC values ranging from 0.39 to 0.78 mg/ml. The methanolic extract of B. disticha leaves and outer scales of bulb displayed good activity against Klebsiella pneumoniae at MIC 0.78 mg/ml. The methanolic extract of B. disticha bulb outer scales also displayed good inhibition against Proteus vulgaris at MIC 0.78 mg/ml, with the root extract exhibiting activity against Shigella flexineri (MIC value of 0.078 mg/ml). Concerning antifungal activity, B. disticha extracts showed very poor inhibition properties against the fungal isolates. Anti-mycobacterium potential of B. disticha extracts (methanol and distilled water) was evaluated using micro-dilution bioassay in 96-well microtiter plates. The plant parts tested were the roots, bulb inner scales, leaves and the bulb outer scales. The highest activity against Mycobacterium tuberculosis was observed with the root methanol extract at MIC 0.78 mg/ml. The anti-inflammatory properties of B. disticha were investigated using the 5-lypoxygenase (5- LOX) assay. The overall anti-inflammatory activity results for the B. disticha extracts were poor; at low concentrations, the plant displayed negative results. The leaves methanol extracts did show little activity at 0.4 mg/ml. , Thesis (MSc) (Botany) -- University of Fort Hare, 2021

- Description: Background: Cancer burden is a global public health concern. It is associated with high morbidities and mortalities worldwide. Over the past decade, there has been a constant increase in the incidence of cancer cases affecting mostly low-income countries and middle- income countries. South Africa as a middle-income country is also affected by this cancer rise. The limited access to oncology services contributed to the late presentation and late diagnosis. In the Eastern Cape, oncology services were previously offered in Port Elizabeth and East London only. Oncology unit was recently opened in Mthatha to decentralize oncology services in the province. The purpose of the study was to explore the experiences of patients with cancer regarding decentralization of oncology services at a public tertiary hospital in the Eastern Cape province of South Africa. Objectives were to describe experiences of patients with cancer regarding decentralization of oncology services at a public tertiary hospital in the Eastern Cape, and to describe the quality of oncology services provided by a public tertiary hospital in the Eastern Cape. Methods: a qualitative research approach with a descriptive, explorative, and contextual design was undertaken in this study, to get the perspective of the oncology healthcare service recipients on the decentralization of oncology services at a public tertiary hospital. An interview guide was used to get experiences of the cancer patients attending oncology clinic. Interviews were conducted to 19 participants on a one-to-one basis. With ethical consideration, all COVID-19 protocols were observed. All interviews were transcribed carefully against their audio-recordings. Field notes were also taken by the researcher on what was heard, observed, thought and experienced during the interview process. The concept of trustworthiness was used to ensure rigour throughout this study. Data was analysed by means of thematic analysis. Data was organized into themes using the Tesch’s approach to open coding in qualitative research. Results: seven themes emerged: 1) experience related to a high level of satisfaction with services provided and desired expectations, 2) waiting time, 3) availability of human and material resources, 4) attitude of health care workers, 5) appropriate treatment and care, 6) access to services, and 7) need for improved infrastructural facilities Many patients had positive experiences about decentralization of oncology services in the province. Most patients were happy about travelling short distances, a smaller number of days, using less money and the time it takes to see a doctor. They also expressed their satisfaction on the quality of oncology services rendered in the unit. The waiting times were acceptable, medicines available and staff had positive attitudes towards the patients. The study revealed that, there were complaints about infrastructure, poor hospital record keeping, and lack of resources. The themes which emanated from the recordings of the study showed that patients with cancer, attending oncology clinic at a public tertiary hospital had positive experiences in this decentralized oncology unit. The services rendered at the facility were of acceptable quality. Staff had positive attitude towards their patients. All patients were seen by the doctors within acceptable waiting time, and they all got their prescribed medication. Access to services was much improved in terms of distance, number of days travelled by patients to access the service and time taken to see the doctor for appointments. Conclusion: The hospital must improve its infrastructure, record keeping, security, and expand the services. Put more focus on cancer awareness programs. , Thesis (MPA) -- Faculty of Health Sciences, 2021

- Description: This study aimed to explore the experiences of unmarried fathers who are denied access to their biological children among amaXhosa communities in Mqanduli, Eastern Cape Province. This study also endeavoured to answer the following research questions: (i). what are the challenges encountered by unmarried fathers who are denied access to their biological children among amaXhosa communities in Mqanduli, Eastern Cape Province? (ii). what are government official's perceptions on experiences of unmarried fathers who are denied access to their biological children among amaXhosa communities in Mqanduli, Eastern Cape? (iii) What are the implications of denial of access of unmarried fathers to their biological children among amaXhosa communities in Mqanduli, Eastern Cape Province? This study adopted a qualitative approach within a phenomenological case study research design. A sample of forty participants comprising twenty unmarried biological fathers, seven statutory social workers, three presiding officers of children's court and ten cultural custodians was interviewed. The study revealed the following challenges: payment of pregnancy damages and bride price, unemployment, conflict with the maternal family, poverty, psycho-emotional breakdown, cultural responsibilities, terminated intimate partner relationship with the mother of the child, financial constraints, and lack of emotional and moral intelligence. The study recommends the development of a new 'family policy' to ensure integration of customary cultural practices and the legislative frameworks to provide a detailed parental-document to assist the new generation of parents in maintaining good parenting relations. Further, the study recommends the establishment of champions against absent and uninvolved fathers, where young men will explore fatherhood roles and develop educational and preventative strategies. , Thesis (MSW) -- Faculty of Social Sciences and Humanities, 2021

- Description: This research study was motivated by the fact that little is known about the topic and that older persons living in Mdantsane Township are heavily reliant on public transport such as taxis, trains, mini-taxis and buses which are, arguably, not suitable for transporting older persons. Through this research project, the researcher hoped to provide information which may contribute to better understanding of this phenomena, identify barriers in the transport system and get a better understanding thereof. This study utilized a qualitative research approach with an exploratory research design. Semi-structured interviews were used to collect data from 30 elderly persons living in Mdantsane Township, and thematic analysis was used to analyse data. Three themes and sub-themes were generated and later linked to the research questions namely: What are the experiences faced by older persons in using public transport? How do these experiences and challenges affect the quality of life of older persons using public transport? What do older persons view as potential barriers in using public transport? The findings highlighted that elderly people living in Mdantsane Township rely on public transport for participation in social and economic activities of the community as well as access to essential services. Consequently, lack of sufficient income among older persons affect their quality of life in relation to using public transport in that they cannot access all the services they need. They also indicated that there are several barriers for older persons against using public transport which include, concerns about personal safety, safety of items, public transport running late, behaviour of younger passengers and taxi conductors and lack of cleanliness among some drivers, to name a few. , Thesis (MSoc Sci) (Social Work) -- University of Fort Hare, 2021

- Description: This research study was motivated by the fact that little is known about the topic and that older persons living in Mdantsane Township are heavily reliant on public transport such as taxis, trains, mini-taxis and buses which are, arguably, not suitable for transporting older persons. Through this research project, the researcher hoped to provide information which may contribute to better understanding of this phenomena, identify barriers in the transport system and get a better understanding thereof. This study utilized a qualitative research approach with an exploratory research design. Semi-structured interviews were used to collect data from 30 elderly persons living in Mdantsane Township, and thematic analysis was used to analyse data. Three themes and sub-themes were generated and later linked to the research questions namely: What are the experiences faced by older persons in using public transport? How do these experiences and challenges affect the quality of life of older persons using public transport? What do older persons view as potential barriers in using public transport? The findings highlighted that elderly people living in Mdantsane Township rely on public transport for participation in social and economic activities of the community as well as access to essential services. Consequently, lack of sufficient income among older persons affect their quality of life in relation to using public transport in that they cannot access all the services they need. They also indicated that there are several barriers for older persons against using public transport which include, concerns about personal safety, safety of items, public transport running late, behaviour of younger passengers and taxi conductors and lack of cleanliness among some drivers, to name a few. , Thesis (MSoc Sci) (Social Work) -- University of Fort Hare, 2021
