- Description: Rangelands are ecological systems largely used for extensive livestock production, which continually play a vital role in developing the economy of rural communities worldwide. These ecosystems also have the potential to provide vital secondary resources like medicinal plants, firewood and wild foods. This study assessed the impacts of management practices on rangeland condition at Tukulu communal farm in the Eastern Cape province of South Africa. Communal farmers’ perceptions were also investigated on vegetation change and awareness to climate variability. A structured questionnaire with open-ended and closed questions was used to interview communal farmers about several components of their rangeland, their awareness to climate variability and their household demographics were recorded. A rangeland condition assessment with the use of a three-tier system was used to determine vegetation condition and assessment of vegetal change over the past ten to twenty years. Botanical species composition, biomass yield, basal cover, woody plant density, browsing units and soil chemical composition were measured. Tukulu communal rangeland was demarcated into three homogenous vegetation units (HVU) namely, open grassland, scattered bushland and dense bushland. Sample sites of (100×50 m)2 with four replicates were constructed in each HVU. Herbaceous vegetation and basal cover were determined along 100 m transects in each sample site using a step-point method. Aboveground biomass production was estimated using a quadrat system following a systematic sampling by cutting all material within 0.25 m2 quadrats located along 100 m transects. Woody plant density (plants/ha), tree equivalents (TE/ha) and browsing unit (BU/ha) were estimated from the number of woody plants, total woody heights and the number of acceptable and available (<1.5 m) woody species. Soil sample analysis was conducted to determine OC, P, K, N, Ca, Mg, Na, Zn, Cu, and Mn and soil pH in all three HVUs. The respondents consisted of 65 percent males and 35 percent females with an average of about five persons per household. The study revealed that communal farmers at Tukulu were fairly knowledgeable about the changes that have occurred in their rangeland. All respondents 100 percent perceived that their rangeland had changed from good to poor condition. This was characterized by the shift from grass dominance to woody plant encroachment. These changes were linked to the perceived changes in climate. Farmers at Tukulu communal area were generally aware of the changes in climate, 95 percent of the respondents’ perceived changes in weather patterns such as changes in rain seasons, hot weather conditions, unpredictable rainfalls, drought, heavy winds and increased temperatures. The results revealed that Tukulu communal rangeland comprised of high species diversity. Twenty-one herbaceous species and 24 woody species were recorded at Tukulu rangeland. The grass species composition was characterised by 71 percent Increaser II species, 24 percent Decreaser and 5 percent Increaser I species. A highly palatable Decreaser species Themeda triandra decreased in abundance from open grassland to scattered bushland. There were no significant differences (p>0.05) in biomass yield in all three HVUs. However, scattered bushland 761.5 kg/ha and dense bushland 735.8 kg/ha had higher biomass yield when compared to open grassland 688.5 kg/ha. Bush encroachment was observed in dense bushland as the woody plant density 4487.5 trees/ha and tree equivalents 3451.3 trees/ha were significantly (P<0.05) higher than the recommended threshold standards of 2400 trees/ha and 2500 TE/ha. Scattered bushland had tree density of 1900 trees/ha and tree-equivalents of 1534.3 TE/ha. Soil macro and micro nutrients differed significantly between the different HVUs. The levels of Na, Ca, Mg, Cu, Mn differed significantly (p<0.05) between HVUs, increasing from open grassland to dense bushland. Organic carbon concentrations were higher under tree canopies in dense bushland. However, the levels of phosphorus and potassium were higher in open grassland than in the wooded areas. Soil pH in scattered bushland (5.3) and dense bushland (5.18) were significantly higher (p<0.05) than in open grassland (4.89). This study shows complications in management policies governing the Tukulu communal area. There is a need to merge both scientific and indigenous ecological knowledge to ensure the desired outcomes, as this could indeed offer some great insights for communal areas. Therefore, a rangeland rehabilitation programme should be implemented at Tukulu communal rangeland, which will address the issue of bush encroachment and implement a rotational grazing system by fencing camps that will be based on acceptable stocking rates.

- Description: Globally, countries, institutions, and organizations are investing time, resources, and human capital on finding best solutions to address poverty, inequality and unemployment; and importantly on achieving sustainable development. This study sought to investigate how social enterprises in Buffalo City Metropolitan Municipality (BCMM) contribute to sustainable social development within the municipality and the country at large. The study endeavoured to answer the following research questions: what is the knowledge level among the selected stakeholders on social enterprise in BCMM? What is the scope, application, and sustainability of selected social enterprises in BCMM? What is the contribution of selected social enterprises in social development in BCMM? What are the bottlenecks associated with the application of social entrepreneurship in BCMM? These questions were answered through mixed methods approaches and techniques, where both qualitative and quantitative data was collected and analysed. The data was collected through in-depth interviews (key informant technique) and a min-survey which was administered to users of the social enterprises. Qualitative data was analysed thematically, while quantitative data was statistically analysed with help of SPSS software. The interpretation of the findings was premised on pragmatic and transformative paradigms. The study further used theoretical lenses such as empowerment theory, capability approach and positive theory of social enterprise to support and explain the findings. The main findings showed that: the selected stakeholders conceptualized social enterprises through the African lens of communal living; the social enterprises widely provided their services across a range of sectors and geographical locations; the social enterprises had direct and indirect contribution to socio-economic development in BCMM. This was specifically through provision of employment, training and skill development among others; the future of social enterprises in the country is bright as many sectors presented opportunities for social investment; and social enterprises face financial constraints, lack of skills in the sector, and competition from the mainstream market. The recommendations from this study address government entities, social services providers and practitioners, social enterprises, and researchers on pertinent endeavours to improve the growth and development of social enterprises. The study concludes that social enterprises are: vital vehicles of socio-economic development, more especially for the marginalized segment of the populations; tools for reducing inequality; platforms for innovations, community participation and conduits of empowerment interventions. Thus, social enterprises play dynamic role and presents potential for capable sustainable social development in the local communities and the South African community at large.

- Description: Tuberculosis is caused by Mycobacterium tuberculosis. The emergence of drug-resistant strains of this organism has become a global public health problem. In the continuing search for effective treatment, polyherbal medicines offer a great hope in the development of alternative drugs for the treatment of tuberculosis. The use of herbal formulations for therapeutic purposes has significantly increased in the developed and developing countries because of their curative property, less toxicity and minimal side effects. However, there is little information on their safety and effectiveness in the literature. To address this, polyherbal medicines used for the treatment of tuberculosis in the Eastern Cape Province of South Africa were evaluated. Ethno-medicinal survey was conducted through semi-structured questionnaires coupled with informal conversations with the herbal sellers in five communities in the study area. Bacterial and fungal DNA was extracted from the polyherbal medicines purchased. A fragment of the bacterial 16S rRNA gene and internal transcribed spacer region of the fungal rRNA operon were amplified with universal primers 27F and 518R, and ITS1 and ITS4 respectively. Following standard procedures, the amplicons were finally run on Illumina’s MiSeq platform. Furthermore, the remedies were screened against Mycobacterium tuberculosis H37Rv using Middlebrook 7H9 media and MGIT BACTEC 960 system. Agar dilution method was used to determine the minimum inhibitory concentration (MIC) of the remedies against eight bacteria and three fungi isolates. The herbal preparations were assayed for their toxicity using hatchability success and larval mortality of Artemia salina Leach. Finally, their nutritive properties were analysed using an inductively coupled plasma optical emission spectrometer for mineral analysis while the vitamins were determined using standardized methods A total of nine polyherbal preparations were collected. The herbs used for the preparation of these remedies belong to 20 families. Apiaceae [5(25 percent)] was the most prominent plant family used, followed by Liliaceae [4(20 percent)], Strychnaceae [4(20 percent)], Rutaceae [4(20 percent)] and Hypoxidaceae [3(15 percent)]. The two most frequently used plants were Allium sativum L. (Liliaceae) and Strychnos decussata (Pappe) Gilg. (Strychnaceae). Rhizomes was the most common parts used, followed by the roots and barks. The herbal medicines were prepared mainly by infusion and decoction. The presences of pathogenic and non-pathogenic bacteria were identified in the polyherbal medicines. Generally, the most common bacteria identified from the samples were Bacillus sp., Enterobacter sp., Klebsiella sp., Rahnella sp., Paenibacillus sp., Clostridium sp. and Pantoea sp. The predominant mycoflora obtained belongs to different genera or species of fungi; these include Alternaria, Candida, Ramularia, Cladosporium, Penicillium, Aspergillus and Malassezia. The susceptibility testing revealed that all the remedies contain anti-tubercular activity against M. tuberculosis H37Rv at concentrations below 50 ug/ml. Seven of the polyherbal preparations showed activity at concentrations below 25 ug/ml. The MIC values exhibited inhibitory activity at 1.562 μg/ml. However, isoniazid showed more inhibitory activity against M. tuberculosis at 0.05 μg/ml when compared to the polyherbal remedies. The inhibitory activity of the polyherbal medicines based on the overall MIC revealed that Hogsback first site (HBfs) and Fort Beaufort (FB) remedies were the most active remedies against the bacterial isolates at the concentration of 2.5 mg/mL. Among the nine herbal formulations, only King Williams Town site A (KWTa) remedy showed activity against Aspergillus niger and Aspergillus fumigatus with the MIC valve of 2.5 mg/mL. While King Williams Town site C (KWTc) and Hogsback third site (HBts) had the highest activity at 1.25 mg/mL against Candida albicans, the remaining remedies were active at 2.5 mg/mL. The percentage hatchability of 44.42 percent, 42.96 percent and 39.70 percent were observed in A. salina cysts incubated with herbal preparations from KWTa, HBfs and HBts respectively. The hatching success of the cysts in these remedies was significantly higher than the positive control (nystatin) and the negative control (sea water) at p < 0.05. The mortality of A. salina nauplii incubated in Alice (AL), King Williams Town site B (KWTb) and KWTc remedies were significantly higher than when larvae were incubated in both controls. Based on Meyer’s index, the LD50 of each polyherbal medicine was between 2.9 and 4.0 mg/ml, the LD50 values greater than 1 mg/ml, an indication that they are not toxic. The polyherbal preparations were found to be rich in vitamins and mineral nutrients. Calcium was the highest macronutrient detected while the lowest nutrient was phosphorus. Iron was the highest micronutrient in the majority of the polyherbal preparations while the lowest value was recorded for copper. Vitamin C was absent in the herbal preparations while vitamin A and E were detected. This study provides significant ethno-medicinal information on polyherbal medicines used for the treatment of TB in the study area. The presence of the identified bacteria and fungi in the herbal formulations is a cause for concern. However, the ability of the remedies to possess activity against Mycobacterium tuberculosis and other pathogenic microorganisms associated with tuberculosis infection makes them potential sources of new antimycobacterial agents. Also, they are rich sources of mineral nutrients, and are as well non-toxic, thus, they are safe for consumption. In view of their anti-tubercular properties, this study has provided a better understanding of the reasons why TB-patients make use of these polyherbal formulations. Also, the study supports the folkloric use of polyherbal medicines in the treatment of tuberculosis in the Eastern Cape Province, South Africa.

- Description: Leukaemia like other cancers is a public health issue, and coupled with the issue of drug resistance, toxicity and refractory disease novel treatments both as definitive and supportive care become necessary. The dissertation was designed to evaluate two medicinal plants (Opuntia stricta and Pelargonium inquinans) and their antineoplastic potentials. The phytochemicals analyses were done using standard methods with three different solvents (acetone, aqueous and ethanol). Vitamins analyses was also done using standard methods. The result revealed that vitamin A,C and E were present in the plants. Cell based anti-inflammatory activity were carried out using RAW264.7 macrophages cell, and COX-2 and NO expression as inflammatory markers. Cell based cytotoxicity and antineoplastic activity was investigated using RAW 264.7 macrophages cell, U937 and Jurkat cells. The results of the phytochemical analyses using GC/MS showed that phenols, flavonoids, flavonol, tannin, proanthocyanidin, saponin, alkaloids and phytate were present in these plants. In vitro antioxidant activity was carried out using nitric oxide (NO), alpha, alpha-diphenyl- β-picrylhydrazyl (DPPH), hydrogen peroxide (H2O2), phosphomolybdenum activity, and iron reducing power (FRAP) techniques. The results of the antioxidant activity showed both plants had antioxidant properties that can be attributed to the phytochemical and vitamins contents. The results showed that both plants had anti-inflammatory properties which can also be attributed to their phytochemicals. The GC-MS analysis of the essential oils of both plants showed the presence of monoterpenes, sesquiterpenes, fatty acids, and esters. The results showed that O. stricta extracts have mild cytotoxicity, while P. inquinans have strong cytotoxicity. The cell cycle analysis showed Pelargonium inquinans extracts induced G0/G1 phase arrest and cleaved caspase-3. This study has shown the antineoplastic potential of P. inquinans which may be attributed to some phytochemicals in it such as carophyllene, humulene, beta myrcene and beta pinene.

- Description: Health Communication plays an important role in health sustenance. It is cardinal to disease prevention, health promotion and quality of life. Water-borne diseases are known to pose a significant threat to global health and has claimed many lives. This study seeks to evaluate Raymond Mhlaba Local Municipality’s communication strategies employed in reducing the risk of water-borne diseases outbreak in the community. The research method used for this study is mixed method. In-depth interview and questionnaire was used to collect data. The two sampling procedures that were used in this study are purposive sampling for the qualitative aspect of this study and simple random sampling for the quantitative aspect of this study. The conclusion that was drawn from this study is that Raymond Mhlaba (formerly Nkonkobe) Local Municipality makes use of a communication strategy, which is awareness campaign, in educating its people about water-borne diseases and its prevention but the information is limited in its reach. This study recommends that the awareness campaign done by Raymond Mhlaba (formerly Nkonkobe) Local Municipality should be embarked on more frequently because the more the messages are reinforced for a long time, the more the people in the community are able to remember and the greater the likelihood that they will act upon the message. In addition, Raymond Mhlaba (formerly Nkonkobe) Local Municipality should carry out evaluations like this research at least quarterly in order to assess the impact of the awareness campaigns on the Community, which can also be used as a tool to educate the people of Raymond Mhlaba Local Municipality about Water-borne diseases. Finally, social media is a new trend that most people are now into, most especially the youths; Raymond Mhlaba (formerly Nkonkobe) Local Municipality should key into this and educate the public on platforms on social media as it can be seen as a form of reinforcing health information.

- Description: Health Communication plays an important role in health sustenance. It is cardinal to disease prevention, health promotion and quality of life. Water-borne diseases are known to pose a significant threat to global health and has claimed many lives. This study seeks to evaluate Raymond Mhlaba Local Municipality’s communication strategies employed in reducing the risk of water-borne diseases outbreak in the community. The research method used for this study is mixed method. In-depth interview and questionnaire was used to collect data. The two sampling procedures that were used in this study are purposive sampling for the qualitative aspect of this study and simple random sampling for the quantitative aspect of this study. The conclusion that was drawn from this study is that Raymond Mhlaba (formerly Nkonkobe) Local Municipality makes use of a communication strategy, which is awareness campaign, in educating its people about water-borne diseases and its prevention but the information is limited in its reach. This study recommends that the awareness campaign done by Raymond Mhlaba (formerly Nkonkobe) Local Municipality should be embarked on more frequently because the more the messages are reinforced for a long time, the more the people in the community are able to remember and the greater the likelihood that they will act upon the message. In addition, Raymond Mhlaba (formerly Nkonkobe) Local Municipality should carry out evaluations like this research at least quarterly in order to assess the impact of the awareness campaigns on the Community, which can also be used as a tool to educate the people of Raymond Mhlaba Local Municipality about Water-borne diseases. Finally, social media is a new trend that most people are now into, most especially the youths; Raymond Mhlaba (formerly Nkonkobe) Local Municipality should key into this and educate the public on platforms on social media as it can be seen as a form of reinforcing health information.

- Description: This study sought to evaluate the development and use of Institutional Repository by staff and students at the University of Fort Hare (UFH) in Eastern Cape, South Africa. In this study, staff comprised of academic staff (lecturers) and library staff. The aim of this study was to investigate the development and use of Institutional Repository at UFH. To achieve the objectives, both qualitative and quantitative research methodologies were employed. Data was collected through questionnaires and face-to-face interviews. Purposive sampling technique was used to select the participants of the study. Qualitative data was analysed thematically while, quantitative data was analysed statically by help of SPSS software. The results showed that: library staff and management are aware and provide support for the development and use of the Institutional Repository at the UFH; awareness level of IR among lecturers and students is still low; the infrastructure available for the use of IR is not well developed; and lastly, library users which consist of students and academic staff face various barriers in the use and support of IR development. The study recommended for dynamic training, and marketing of IR through seminars and workshops should be started by expert affiliations and universities administration to advance the idea of IR among the University community. Low levels of awareness of the university repository, funding and shortage of library staff remains an issue and could be addressed by further investigating the effectiveness of different communication channels. It is pertinent that the findings of this study would be useful in various tertiary’s institutions of higher learning across the globe in order to embark on IR.

- Description: This study analysed the capacity of Limpopo Water Services Authorities in providing access to clean drinking water and decent sanitation. The study raised issues of the state of access to clean drinkable water and decent sanitation through the prism of the municipality and the community. Arguably, the provision of water and sanitation services collapsed, at the level of local government, during the Jacob Zuma administration, because of the escalation of violent service delivery protests due to poor administration and management. It was discovered that all Water Services Authorities owe the Department of Water Affairs exorbitant amounts of money, well into the range of millions of Rands. This prompted the Water Boards to issue threats that they would limit the provision of bulk water. Such austerity measures compromised citizens who regularly pay for the services provided; hence, it sparked violent protests. One of the major drawbacks of the current institutional arrangements arose from the overlapping mandates of the Department of Water Affairs, Cooperative Governance and Traditional Affairs, Water Services Authorities, Local Municipalities and the Department of Human Settlements. Consequently, the structural design of the intergovernmental system should enforce synergy between all water and sanitation units. The reports produced by all units must be scrutinised, debated and followed through. The study was anchored in a qualitative research design, grounded in the descriptive approach. Interviews were conducted to acquire information from politicians, administrators and community members. It was discovered that there were no skilled personnel in Water Services Authorities and Water Service Providers and, as such, institutional capacity was in disarray. More importantly, during the interviews conducted for this study, it surfaced that financial mismanagement in all municipalities is conspicuously unacceptable, especially unauthorised, irregular and fruitless expenditures. These situations prevailed under the supervision of the well-established oversight institutions that were tasked to enhance the monitoring and evaluation for good governance, such as The Auditor General of South Africa, the Human Rights Commission and the Public Protector. Professionalism and quality performance remain at a low point, with no improvement in service provision. Therefore, radical enforcement of monitoring and evaluation through Auditor General of South Africa, Human Rights Commission and Public Protector, amongst others, is critical to any attempt to disrupt the status v quo. In addition, the appointment of the heads of these oversight institutions must be removed from the Presidency and be made by the Chief Justice. The encounters confronting Water Services Authorities and Water Service Providers are complex and may not be resolved by the government alone, without the participation of the private sector and other actors such as Civil Society Organisations, the business community and public entities. Therefore, an area for further research could be an examination of attempts to introduce effective integrated water and sanitation governance structures, and monitoring and evaluation mechanisms, under robust public scrutiny in order to inform immediate and long-term interventions.

- Description: This study examined the invariant condition of equating test scores of examinees for the Malawi School Certificate of Education (MSCE) Computer Studies test across rural and urban areas of Zomba District in Malawi. Equating of test scores to create comparable and interchangeable scores in assessment is increasingly becoming popular to most examining bodies. However, the Malawi National Examinations Board (MANEB) and many other examining bodies in Africa and Europe do not embrace test score equating in their assessment systems. The consequences of not equating test scores have not been clearly documented. Furthermore, there are no proper equating designs for some agencies to employ because they administer tests annually to different examinee' populations and they disclose all items after each administration. Therefore, the study sought to establish whether the invariant condition of equating test scores of examinees holds for the Malawi School Certificate of Education (MSCE) Computer Studies test across rural and urban areas of Zomba District in Malawi. Data were collected through two Computer Studies tests which were administered to a sample of rural and urban examinees. The data were analysed using means, standard deviations, T-tests and Statistical Package for the Social Sciences (SPSS). The study revealed that score distributions and test difficulties were similar across test forms signifying that test score equating is necessary. The classification of examinees into rural and urban geographical areas across the test forms were different before score equating, but similar after score equating. The equating of scores for the two sub-populations of rural and urban examinees displayed similarities in their Standard Error of Equating (SEE) values but they were not the same. The equated scores for rural examinees displayed more equating errors than the equated scores of urban examinees, indicating a better performance in Computer Studies by urban examinees than the performance of rural examinees. The study further revealed that equating of test scores was necessary because it was almost impossible to construct multiple forms of a test that were completely parallel. Even though test developers use the same test specifications to develop test items and make every effort to develop items in one test form as similar as possible to the items in another test form, the study has shown that there is no guarantee that the difficulty levels of the items would be the same. Among the many recommendations made, one major one is that the Malawi National Examinations Board (MANEB) should embrace the practice of equating test scores to improve fairness of decisions which are made on examination results.

- Description: This study examined factors that influence the academic performance of Grade 12 learners in English Language (L 2) in the Oshikoto Region. The theoretical framework that underpinned and guided the present study was the Systems Theory of von Bertalanffy (1930), supplemented and complemented by the School Context Model of Bascia (2014). These helped me to understand how the school context shapes core processes of teaching and learning. The study sample consisted of four principals, eight parents, eight teachers and thirty two learners who were purposively sampled from four selected secondary schools. The study was anchored in the pragmatic paradigm and it adopted the mixed methods research approach. Data collection instruments consisted of questionnaires, semi-structured interviews and focus group discussions. Major findings were that, both Grade 12 English Language (L 2) teachers and learners lack English Language proficiency. This was due to lack of exposure to the English Language. The study also noted lack of learning materials in both school and the home. Major recommendations were that schools (principals) should expose both teachers and learners to English Language by coming up with policies that make it mandatory for teachers and learners to use English while at school. Teachers should also actively involve learners in their learning by using methods such as debates and drama. The study also recommended that the Ministry of Education, schools and parents work together to provide adequate reading materials for learners. For future research, the study recommended an in-depth qualitative study to test the findings of the present study.

- Description: The focus of this study is to investigate factors that cause women to remain in abusive relationships. It has also focused on investigating the experience of abuse, the consequences of abuse and the support that women desire during their time of abuse. Domestic violence against women in South Africa and globally has been increasing by the day. In 2017 there has been more than ten reports of women who have been battered by their partners in South Africa and they were reported dead, therefore the aim is to focus on investigating the reasons why women stay in abusive relationships. The research approach for the study was qualitative in nature. The study adopted snowball sampling as the sampling technique for the study and ten women who have left their partners for two years or longer were interviewed. Interviews were conducted at Living Waters Victim Empowerment Centre in East London and the data was analysed using Interpretative Phenomenological Analysis. The key finding of the study is that financial dependency, culture and children play a major role for women to stay in abusive relationships. All ten participants who were interviewed were aware that they were being abused, however, they used unemployment, children, culture and love for their partners as their reasons for remaining in abusive relationships. The study found that women have been affected physically, emotionally and psychologically by the abuse which has negatively impacted their daily functioning. 4 This study also discovered that if women receive family support during their time of abuse, they will be able to make informed decisions and leave their abusive partners. One of the recommendations of the study is that women should be encouraged to expose the abuse they are enduring through campaigns and workshops. They should also be taught skills that will assist them to escape abusive partners. There is also a need for educational programs that will focus on men and the impact of domestic violence on women and children.

- Description: The aim of the study was to explore the experiences of student nurses regarding the implementation of CBE and allow them to tell their story of how CBE impacted to their academic experience. Purposive non-probability sampling was the method of choice. The following research question guided this study: What are the experiences of nursing students at the nursing college on the implementation of CBE as a teaching-learning strategy? The participants in this study were the fourth year students registered in the four year diploma and have been exposed to CBE, according to regulation 425 of the Nursing Act, 2005(Act No.33 of 2005). Fifty (50) students voluntarily participated in the focus groups discussions. Data analysis was done concurrently with data collection. Data was analysed manually as it was categorised into themes, categories, and subcatagories. For this study, a category system/ template was developed to code the data according to the categories, therefore related concepts were grouped together to facilitate the coding process. The final analysis led to the development of a report presenting the interpretation and presentation of results. RESULTS The study results revealed that students had benefited from CBE as a teaching learning strategy. Furthermore, participants reported that CBE had an impact in their training in terms of acquisition of skills, personal and professional growth and correlation of theory to practice. Discussions of findings, along with recommendations for practice conclude the study. Suggestions might be made to improve ways in the implementation of CBE in the nursing college

- Description: The constant, excessive and frequently uncontrollable abuse of alcoholic beverages and drug related substances continues to have many devastating effects on family members of the abusers. The impact can be explored in various ways, but the findings are likely to be hand in glove regardless of the causes associated with this phenomenon. This study aimed to explore the experiences of family members living with individuals who abuse alcohol and/or substances through case studies conducted in Khayelitsha, in the Western Province of South Africa. The study was conducted to gain greater insight into the experiences of the family members in order to provide the appropriate assistance to help them deal with these issues. From the data that was captured and analysed, it was clear that alcohol and substance abuse inflicted profound suffering on family members. It contributes to high levels of interpersonal conflict, domestic violence, child abuse and neglect, financial problems as well as health issues for all parties involved - causing extreme emotional pain and suffering. Living with an alcohol or substance abuser inevitably results in financial burden, dysfunctional relationships and family life in addition to impacting on safety needs. Furthermore, the results have shown that family members of alcohol and substance dependents develop psychological and mental distress; anxiety, and insomnia. Likewise, the family members develop psychophysiological symptoms such as high-blood pressure and chronic headaches. With regards to rehabilitation, family members reported exclusion from rehabilitation programs and lost their belief in self-rehabilitation or detoxification.

- Description: Identity is a complex concept involving not only who one is, but who one is becoming. Identity is often shaped by one’s experiences and by one’s environment. The identity of bodybuilders is constructed through their experiences, which are often hidden. Using Participant Action Research, specifically Photovoice, the participants were provided a platform to share their experience from their own perspective. This research aimed to explore the identity of bodybuilders and what shapes their identity. Four male bodybuilders between the ages of twenty-one and twenty-eight participated in the study. The sample of participants consisted of two black males and two Caucasian males. The four athletes either selected or took photographs of significant aspects in their life that they felt contributed to their identity. The researcher conducted semi-structured interviews with the athletes regarding the photographic images they took. The interview transcripts and photographs were analysed using Thematic Analysis. Five main themes were identified: Diet (including water intake and on/off season cycles), Presentation of physique, Psychological impact on self-confidence, Risks involved with bodybuilding and Impact on personal life. Significances of the themes were discussed with the aim of increasing awareness regarding the experience of bodybuilders and how their experience as bodybuilders has shaped their identity.

- Description: The aim of the study is to explore the role of social work intervention in empowering victims of crime in the Alice community. The study used a qualitative research design to collect data from nineteen (19) participants. The findings revealed that people living in rural areas are vulnerable because they do not get the necessary support from the government, social workers and other professional bodies. Yet the role played by social workers to assist victims of crime is not enough because they are few and they do not have enough resources to execute their work. The study reveals that most of the victims of crime were females, others were employed and few of them were unemployed. The study recommends that policy makers need to evaluate the overall impact of different criminal activities by measuring the extent to which dependence changes as policies are changed. Debates should be centred on a discussion of how to design better programs in order to achieve the developmental objectives since it is evident that criminal activities grow day-by-day in South Africa. The study concludes that the researcher hopes that the objectives were adequately handled as they attempted as much as possible to address the possible implications associated with victimisation.

- Description: The study sought to explore the standardization of music and dance styles in relation to worship styles in the CCAP Blantyre Synod in Malawi. The study further sought to understand the factors that influence the selection of songs during worship, and strategies for standardizing the existing songs in the church. The research was guided by the qualitative research approach. The interpretive research paradigm guided the interpretation of data in this study. A case study research design was used to get an in- depth understanding of the issues related to music and dance in the CCAP. The participants were purposively selected and interviews were conducted. Focus group interviews and observation supplemented the data collected through one on one interviews. Data analysis was achieved through a detailed narration of the participants‟ responses and, thereafter, themes were identified for further discussion. The main findings of the study were: factors influencing selection of music during worship services; lack or availability of music selection guidelines; age of choir members; commercialization and instrumentation of music; the use of traditional and classical music in the church; mixed dancing styles being introduced in the church; and the suggestion to use the Bible as framework for resolving conflicts in the church; and the need to train church members on church music. The study recommends the use of detailed and appropriate music guidelines in selecting songs. In cases of conflicting tastes in music, the study has proposed a process of resolving such conflicts within the CCAP of Blantyre Synod. The study also examined music and dance styles but not on other aspects of worship such as prayer and offering. The findings of this study may be useful in advising and resolving challenges associated with the incorporation of music in the church.

- Description: Background and Aim: Despite the use of fundal pressure globally, there is a scarcity of information available on how women experience the application of uterine fundal pressure (UFP) during the second stage of labour. The aim of study was to explore the experiences of women concerning UFP application during the second stage of labour. Understanding women’s perception about UFP is important in informing the generation of new ideas to improve on the application of UFP for better outcomes. Methods: This was a qualitative, interpretive, and phenomenological analysis designed to explore the experiences of women regarding the application of UFP during the second stage of labour. Hermeneutics was applied to interpret the participants’ descriptions of their experiences as they tried to make sense of their exposure to UFP; bearing this in mind, the participants’ own interpretation was not distorted. The researcher immersed herself in each transcript, in order to make sense of each participant’s experiences and to gain a sense of what the participant had experienced during UFP application. Each interview was transcribed and analysed independently; and the convergences and divergences of themes were identified without losing the original meaning of each participant’s description before moving on to the subsequent interviews. The target population was women who had had UFP during second stage of labour. A purposive sampling method was used to select three women who were admitted to the DVDHMOU during the research period and who met the inclusion criteria. Information was collected through individual face-to-face interviews and semi-structured interview guide. The principal question was framed as: “Can you please share with me how you felt when the midwives pushed on your tummy to get the baby out”? An audio tape was used to record the interviews, and a notepad was used to make notes of gestures such smiles or other facial expressions. After each interview, the recorded interview was transferred onto a laptop and a file was opened for the interviewee, identified by a pseudonym. The interviews were transcribed verbatim as Word documents. Trustworthiness was maintained by applying the principles of credibility, transferability, dependability and conformability. Ethical approval was granted by the Ethical Committee of the University of Fort Hare. Permission to conduct the study was sought from the Eastern Cape Research Committee and Buffalo City Metropolitan Health District. Informed consent was obtained from the participants prior to data collection. Each interview was analysed separately after completion. Data was analysed using thematic content analysis applicable to interpretative phenomenological analysis (IPA) studies using six steps: reading and re-reading; initial noting; developing emergent themes; searching for connections across the emergent themes; moving to the next case; and lastly, looking for patterns across cases. Findings: The findings of this study indicated that the informants had feelings of fear, loneliness, worry and tearfulness; but also happiness associated with UFP during second stage of labour. They were also worried and expressed fear and anxiety concerning their infants; and their ability to give birth increased as they get tired in the process of pushing during UFP application. However, seeing their infants for the first time took most of the worries away, and all informants expressed relief when the birthing process was over. They also felt that their birthing experience was a very painful event; and were left alone, and they had not been given anything to drink or eat during labour. Midwives threatened them that their inability to pushing appropriately, could cause the death of their infants, leaving them with feelings of guilt and despair when their babies did not cry directly after birth. The findings demonstrated that midwives did not properly inform women what to expect during the second stage of their labour, whilst the midwives expected birthing mothers to know what was happening to them and how to react. Women in labour therefore depended almost entirely on information received from family members, and went into labour with preconceived ideas about labour pain. Although women do experience pain during the second stage of labour, the application UFP increased their pain. Four main themes emerged from the analysis, which are: perceived severity of UFP pain,emotional/physical reaction to UFP pain, perceptions of UFP and perception of midwives care and treatment. Conclusion: The uterine fundal pressure is not a pleasant experience for the women in the second stage of labour. Labouring women experienced pain, fear, and anxiety. However, they felt a sense of happiness after delivery. Before the application of UFP during the second stage of labour, midwives should explain to women the process of UFP application and what they can expect to happen; and where possible, and after explaining the procedure, midwives should get written permission before they apply the intervention during labour.

- Description: Introduction: The marine environment is rich in the biodiversity of medically significant invertebrate species such as sponges, ascidians, molluscs and bryozoans. Such a diverse environment is a potential source of a great variety of secondary metabolite production. Research in marine natural product discovery is gaining ground with the development of new therapeutic drugs of antimicrobial potential. Aim: This study seeks to evaluate, and identify bioactive compounds obtained from marine invertebrates collected from Phillip’s Reef in Algoa Bay. Methodology: Marine invertebrates were collected from the Phillip’s Reef in Algoa Bay, Port Elizabeth, at a depth of 12 m and the physichochemical parameters at the site of sample collection were recorded onsite. Sampling was done once over the four seasons in South Africa. Sections of each specimen were sent for identification, and extraction of compounds was done using organic solvents [methanol (95percent), hexane (95percent), petroleum ether (95percent), chloroform (95percent) and ethyl acetate (95percent)]. A ratio of 95percent the respective solvents was achieved by the following (1:19), organic solvent combinations [dichloromethane: methanol (1:1), hexane: chloroform: methanol (1:2:1)] and aqueous solution of water. Solvent optimization was done by measuring the absorbance of S. aureus (ATCC 49476) in Mueller Hinton Broth containing crude extracts at 600 nm. The appropriate solvent was then selected for further extraction of bioactive compounds from the specimens. Antimicrobial activity of the crude extracts was evaluated using the standard agar well diffusion method on test pathogens, namely, methicillin-resistant Staphylococcus aureus (ATCC 49476), clostridium difficile (ATCC 9689), Pseudomonas aeruginosa (ATCC 10145), Candida albicans (ATCC 10231) and Aspergillus fumigatus (ATCC 204305). Different concentrations of the crude extracts were used [100percent, 80percent, 60percent, 40percent and 30percent (v:v)] and the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) were determined. Selected bioactive crude extracts were further evaluated for phytochemicals before being purified by subjecting them to Sephadex-G75 column chromatography, using 75percent ethyl acetate as the mobile phase. Bioactive crude extracts fractions obtained following column chromatography were subjected to Electron Spray Ionization Time of Flight (ESI-TOF) analysis using The Bruker Daltonics maXis compact ESI Quadrupole TOF instrument to detect and identify compounds present. Peak identification was done using the blast software contained in Open Chrom Community Edition (Alder), open source software for chromatography and mass spectrometry spectrum analysis. Results: Sixty-seven different marine invertebrate species were collected over the 4 seasons. A mean temperature of 17.35oC ± 2.06 was recorded over all four seasons with the Autumn exhibiting the highest temperature (20oC). Salinity readings obtained ranged between 35.12 psu and 35.27 psu. A stable mean pH range of 8.08–8.78 was also recorded across all four seasons. Salinity and pH readings conformed to the standards set by the South African Water Quality Guidelines. The Spring season exhibited the highest turbidity of 2.97 NTU compared to other seasons. Ethyl acetate and dichloromethane: methanol (1:1) extracts yielded the best inhibitory results. Approximately 60percent (4/67) of the marine invertebrate specimens showed bioactivity against some of the test pathogens. Both ethyl acetate and dichloromethane methanol crude extracts of S14 and S34 showed a broad spectrum of antimicrobial activity against both bacteria and fungi. The C6 ethyl acetate crude extracts were highly active against MRSA, as inhibition zones of 45 mm were observed. MIC at 30percent concentrations was observed for very few crude extracts against the five pathogens. Sixty-three ethyl acetate crude extracts contained phytochemicals while only 35 dichloromethane: methanol crude extracts contained phytochemicals. Neither ethyl acetate and dichloromethane: methanol crude extracts of S34 (Psammopsinia sp. 1) that were biologically active had any phytochemicals. Canadine, Ginkolide A, Apigenin, Amygdalin, 10-hydroxy-Camptothecin, Catechin, Beta-Peltatin and 6 Ethoxy-3(4'-hydroxyphenyl)-4-methylcoumarin were identified in the crude extracts. Conclusion: Marine invertebrate species located at Phillip’s Reef produce compounds with antimicrobial potential. These compounds are biologically active against human pathogenic microorganisms. The best solvent to use for the extraction of these biologically significant metabolites is ethyl acetate, as this study achieved outstanding results from ethyl acetate crude extracts in the form of high zones of inhibition, for example the sponge Ectyonopsis flabellate, which exhibited mean inhibition zones of 45 mm against Aspergillus fumigatus. Similar bioactivity was also observed with Tedania (Tedania) Stylonychaeta against Methicillin Resistant Staphylococcus aureus. This is the first study done on some of the marine sponges and ascidians in the Phillip’s Reef, and therefore further evaluation of the purified compounds is necessary in order to obtain the identity of the pure compounds and possibly determine the mechanism of action, and synthesize structural analogues for further studies.

There were two Provincial assessments done on National Core Standards in Postmasburg Hospital (overall scores were 32percent in 2013 and 48percent in 2014) and on both occasions, the Hospital failed to comply with the assessments and the implication were a suspected negative impact on the Hospital service delivery. The repercussions could be that the hospital might not be certified or not funded through National Health Insurance following a national assessment if the status quo remains. Aim: The aim of the study was to describe the factors affecting patients’ perceptions of service delivery in order to inform health policy decisions to improve service delivery. Methodology: A quantitative descriptive design was used to collect data on 133 adult patients admitted for a minimum of three days in the different hospital wards. Participants were administered a structured pre-tested questionnaire to collect data relating to their employment status, the number of hospital admissions and the reason for hospital admission. Results: About 41.4percent of participants were neutral or not sure whether the nurses/doctors came often to the ward where they were admitted. The majority (51.9percent) were neutral or not sure whether the quality of food in the hospital was good; 53.4percent expressed uncertainty concerning the adequacy of benches/chairs in the hospital for patients to sit while waiting to be seen by the health worker; and 55.6percent participants were neural or not sure whether the ward/room had enough space for consulting. Asked whether the hospital was user-friendly to disabled persons, 53.4percent participants were not sure. About 43.6percent participants expressed uncertainty regarding the registration satisfactory nature of the procedures in the hospital; the water cleanliness for patients in the hospital (42.1percent); whether their privacy was respected by all the staff within the hospital (51.9percent); permission to be examined and treated (51.1percent); the nurse/doctor who treated them being polite (53.4percent); and the nurse/doctor who treated them being able to answer all their questions about their illness (56.8percent). On whether they will visit the hospital again, 49.6percent participants were uncertain. The majority (69.7percent) agreed that all prescribed medicine was available in the hospital; the staff explained to them on how to use the medicine/pills (67percent); and they were told on how to store their pills/medication (47percent). Gender, education and employment status of the participants affect exactly one dimension each. Females, those with secondary education and employed were more satisfied on the respective dimensions. Conclusion: Patient involvement is an essential feature in healthcare services. Patients influence outcome quality through compliance, defining the right symptoms and physically experiencing treatment. Patient perceptions and satisfaction with service delivery is a multi-dimensional concept that should be studied by operationalising it within its context. Consequently, a conceptual model to understand and measure patient perception and satisfaction of service delivery and care quality in hospital health care services is proposed.
