- Description: Drug and substance abuse amongst secondary school children is a universal phenomenon and it has increased at an unprecedented rate over the past decade and still rising. In South Africa, drug and substance abuse has continued to ruin the youth and subsequently education despite various measures taken to stop it. This study aimed at investigating teachers’ views and experiences on drug and substance abuse by learners. Teachers have a responsibility to ensure that learners do not involve themselves in the use of drugs and substances at school. A case study research was conducted to investigate the views of eight teachers in two selected rural secondary schools in the King William’s Town Education District. Qualitative research guided the research process and the interpretivist paradigm served as bases for data collection. Face-to- face semi-structured interviews and focus group discussions were used to collect data. It emerged from the data that alcohol and substance abuse by learners have a negative effect on their academic work as learners abusing drugs could not concentrate on their studies and bunk classes. The data also showed that learners become violent and most of the time important time that could have been spent teaching is lost dealing with alcohol and substance abuse users. The findings also indicated that there was a lack of parental and community support to effectively deal with drugs in schools. From the findings it can be concluded that there are serious social and academic problems that are caused by drug and substance abuse in the rural schools. It can also be concluded that teachers and school managers had no clear and coherent strategies to deal with drug and substance abuse in schools. In view of the above, I recommend that a comprehensive model should be adopted to fight dug and substance abuse by learners.

- Description: The main aim of the study is to determine the views of teachers in the East London district on the influence of quintile-based school categorization on the culture of teaching and learning in No Fee Schools (NFS). The study is motivated by the high rate of underperformance registered by the NFS despite the huge amount of support and intervention directed to them. The study is located in the interpretive paradigm and hence used, was a qualitative approach and case study design. Purposive sampling technique was followed to identify participants. Twelve (12) teachers from three research sites, which are NFS, participated in the study. Data was gathered through observations, document analysis and one-on-one semi-structured interviews, respectively. In each school, a principal, a School Management Team (SMT) member and two Grade 12 teachers were interviewed as participants in order to enrich the study. The study is underpinned by the Social Identity Theory (SIT) which is guided by the pursuit of evaluative positive social identity through positive intergroup distinctiveness, which is, in turn, motivated by the need for positive self-esteem (Tafjel & Tunner in 1979). Thus, according to Hogg (2006), social identity is motivated by self-enhancement and uncertainty reduction, which causes groups to strive to be both better than and distinct from other groups. This theory afforded the researcher the opportunity to understand how teachers’ personal identity and professional identities are influenced by the categorisation status of their schools as well as by their associates. This study revealed that the no fee categorisation status seems to affect the teacher identity and their professional identities which in turn appears to affect the culture of teaching and learning in NFS. This is indicated by data that some of the teachers in NFS seem to be in denial or feel rejected whilst some are proud and embracing teaching in these disadvantaged schools. The study further reveals inadequacy of the funding systems to address lack of resources in NFS means teaches have to provide for these in one way or another. One of the main findings of this study is that various strategies used by the NFS in trying to enhance the culture of teaching and learning in their schools produces differentiated results depending on teacher’s attitudes, commitment, determination and hard work. The study also reveals that teachers from the same communities as the schools in which they work are more dedicated and willing to go an extra mile to plough back. In addition to this, teachers from similar environments seem to be driven by their backgrounds to help and support destitute learners. Amongst the strategies used in schools, matric revision camp, cell phone policy and parenting of learners by teachers are the most effective in terms of enhancing culture of teaching and learning thereby improving matric results. Moreover, the study further divulges that some of the teachers in NFS are committed, motivated and hardworking despite the contextual factors found in these schools. Furthermore, learners in these schools tend to mirror their teacher’s positive attitudes, hard work and determination towards their work which in turn they apply in their own studies. The study concludes with the findings that the teachers in underperforming NFS have to prove their worth to their associates in affluent schools or high performing NFS. Structural committees used at school levels have a positive contribution in the effective implementation of the intervention and support programs directed at NFS.

- Description: This study reveals the effects of doping on the morphological, structural and optical properties of titanium dioxide (TiO2) nanotubes (TNTs), synthesized by sol-gel template-assisted sol-gel technique. The nanotubes (TNTs) were prepared in anodic alumina membranes (AAM) with a pore diameter range of 110-210 nm by using titanium tetra butoxide as a sol-gel precursor and oxalic acid dihydrate as a dopant source. The synthesized nanotubes were evaluated using scanning electron microscope (SEM), energy dispersive spectroscopy (EDX), fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), confocal Raman spectroscopy (CRS) and photoluminescence spectroscopy (PL). SEM analysis has revealed the presence of closely-packed TNTs, with a modal external tube diameters of 150, 170, 210,190 and 210 nm for the un-doped TNTs, 9 mM carbon doped-TNTs (C-TNTs), 27 mM C-TNTs, 45 mM C-TNTs and 75 mM C-TNTs respectively. The diameters are consistent with the AAM diameter range. EDX spectra revealed the presence of Ti peaks at 0.45 and 4.9 keV corresponding to Kα1 and Kβ1 emission lines respectively. Oxygen exhibits a signal at 0.5 keV corresponding to Kα1 emission line. The occurrence of these peaks in the EDX spectra endorses the existence of Ti and O atoms in the prepared titanium dioxide nanotubes. FTIR spectroscopy has revealed the presence of vibration modes at 580-660 cm-1 indicating the presence of Ti-O bonds and additional vibration modes at 2324 cm-1 resulting from C-O stretching in the C-TNTs. The XRD analysis has revealed the presence of a mixed anatase-brookite phase with diffraction peaks at 2θ angles of 25.49⁰, 38.11⁰, 40.60º, 48.14⁰, 54.58⁰, 63.00⁰, 70.11⁰ and 75.66⁰. Additionally, XRD analysis has revealed elongation of lattice parameter “c” from 9.143 to 9.830 Å with carbon concentration increase. Lattice expansion indicates the possibility of carbon substituting oxygen sites. Raman large area scan has revealed the presence of rutile, brookite and anatase for the undoped samples. On doping the rutile phase of TiO2 has shown to be suppressed by the presence of carbon atoms such that the doped samples consist of brookite and anatase phases only. The Eg1 mode of anatase of the undoped TNTs at 153. 78 cm-1 was red shifted by Δ9.78 cm-1 relative to the bulk anatase TiO2. This was attributed to decrease in particle size, presence of brookite and phonon confinement. Upon doping, the 9 mM C-TNTs, 27 mM TNTs and 75 mM TNTs have shown a red shift of Δ0. 09 cm-1, Δ1. 39 cm-1 and 1.81 cm-1 respectively, suggesting the incorporation of carbon in the TiO2 matrix. CRS depth profiling in the XZ direction has also validated the presence of a mixed anatase-brookite phase at Raman active modes 153.19 cm-1, 208.87 cm-1, 404.55 cm-1, 523.26 cm-1 and 648.55 cm-1. Photoluminescence spectra of carbon doped TiO2 showed two emission peaks at 398 nm attributed to annihilation of excitons while the broad peak at 400-460 nm was attributed to the presence of oxygen vacancies. The peak intensity of the 45 mM C-TNTs has shown a lower PL intensity suggesting that efficiency of charge separation was higher and recombination rate was lower than other carbon containing samples.

- Description: In South Africa, just like in any other country within the African continent, traditional healing remains an integral part of many communities and this is not just restricted to the rural communities only, as is sometimes assumed. The main aim of this research was to explore the approaches of traditional healers in the treatment of HIV/AIDS in the Chris Hani District Municipality, Eastern Cape. The following research objectives were followed regarding the approaches of traditional healers in the treatment of HIV/AIDS: (i) to assess how traditional healers and people living with HIV/AIDS in Tsengiwe village understand HIV/AIDS, (ii) to investigate the reasons people living with HIV/AIDS consult traditional healers in Tsengiwe village, (iii) to assess Tsengiwe village traditional healers’ treatment strategies for HIV/AIDS, (iv) to establish how traditional healers view their role in the treatment of HIV/AIDS in Tsengiwe village. A qualitative research design was utilized, using in-depth interviews with traditional healers and focus group discussions with caregivers and people living with HIV/AIDS respectively. A type of non-probability sampling known as purposive sampling was used. A total of sixteen (16) participants were interviewed. The findings in this research revealed the following themes: (i) HIV/AIDS is incurable and it is understood by symptoms, (ii) belief system entrenched in traditional healing, (iii) cleansing rituals and traditional medicinal remedies and, (iv) strengthening relations between stakeholders. While traditional healers expressed a willingness to work with biomedical professionals in the management of HIV/AIDS, caregivers and people living with HIV/AIDS preferred going to clinics and hospitals for treatment. Furthermore, people living with HIV/AIDS in this research never admitted to consulting traditional healers for their ailments, only saying that they choose to self-medicate.

- Description: This study investigated the tension between the right to freedom of expression and the right to a fair trial in the context of the public broadcasting of criminal trials. The aim of the study was to determine whether the right of the media to broadcast criminal trials can be reconciled with the right of an accused person to a fair trial. To accomplish the above aim, the research undertook a review of the case law relating to televised criminal trials in order to determine how the courts have addressed the fair trial-free expression conflict. The study concluded that the ‘balancing exercise’ employed by the courts does not seem to have addressed this tension. Given that televised criminal trials are prone to sensationalism and the danger of fabrication of evidence, the study concludes that the broadcasting of criminal trials undermines the right to a fair trial. The study makes recommendations that are designed to ensure a proper balance between the freedom of expression as exercised by the media through the broadcasting of criminal trials on the one hand and the right of accused persons to a fair trial on the other.

- Description: Currency crashing is one of the recurring problems in emerging economies. The crashes are as a result of the following factors; poor government policies, fiscal imbalances, trade deficits, higher inflations, monetary policies, and liquidity shortage among others. The crashing of currencies poses socio-economic problems that are devastating to different classes of people. To this end, this study sought to investigate the social consequences of currency crash to the middle class in Zimbabwe with a particular focus on the case of Msasa Park suburb in Harare. The study sought to investigate how the middle class households adapted to the situation induced by the crash of the Zimbabwean dollar, to examine how the currency crisis in Zimbabwe affected consumption patterns of the middle class at a household level and to identify the effects of currency crashes to the middle class’ national feeling and identity. The study utilized a qualitative research method in the form of in-depth interviews and focus group discussions. The process was made possible through the use of purposive sampling and quota sampling to generate the targeted participants of the study. The findings of the study have shown that the crash of the Zimbabwean dollar resulted in massive retrenchments, dwindling work opportunities, shrinkages in salaries and wages of employees particularly the middle class. This led to the rampant growth of the informal sector whereby people ended up engaging into extra economic activities outside their professions so as to supplement their incomes. Moreover, the study has shown that some middle class households began to cut out luxurious goods and prioritize basics. As such, their consumption patterns began to change in that their daily meals were reduced. The main reason given by the participants were that groceries were no longer available in shops. Resultantly, the majority of the participants said that they had to either grow their own food or import it from neighboring countries such as Botswana, Zambia and South Africa. In addition, the study yields that crash of the Zimbabwean dollar exacerbated migration of the working class to other countries. Last but not least, the study has shown that the crashing of the Zimbabwean dollar had effects on the class identity of the middle class in that the majority of them completely lost their status since they were experiencing downward mobility.

- Description: Sheep farming seems to have a rich profile in the improvement of the livelihoods in the deprived parts of developing countries throughout the world. The broad objective of this study is to assess the contribution of sheep production to household welfare under alternative extension regimes. Specifically, this research investigated the methods used to deliver extension services, perceptions of communal sheep farmers towards extension delivery services and contribution of communal sheep production to household welfare. The study was conducted in Nyandeni Local Municipality in the Eastern Cape Province and employed survey data obtained from 105 households practising sheep production. Cross-sectional research design and purposive sampling technique was used. Descriptive statistics was used to examine socio-economic characteristics and extension methods used to improve sheep production. Likert scale was used to rate perceptions of sheep producers and extension services given And a T-test analyses was conducted to test its reliability. Linear multiple regression model was used to estimate the contribution of sheep production to rural household’s welfare. The descriptive statistics results show that males were dominant with a representation of 55.2 percent and 44.8 percent were females. Moreover, the majority of households were aged, being above 61 years on average. The results showed high levels of illiteracy amongst household sheep producers with 54 percent having no formal education and average number of years farmers spent in school was 7 years and less. About 62 percent of the households were married and 54 percent was found to be unemployed. Farming was found to be the major agricultural economic activity. The results also shows that there is one type of extension method used in the area which was the group method through the use of group meetings. This finding was surprising as it was different from the results that were expected given prior information obtained from the literature and extension service. Therefore the study was unable to conclude on which of the extension method was most effective since the households were not exposed to different regimes. From the Likert-scale analysis, although all households received extension services many (58 percent) of respondents were not satisfied with the services they received. In order to run the regression, diagnostic checks were done to check if multicollinearity existed in the variables. Linear multiple regression analysis results indicate that sheep production contributes to household income and welfare. However, household sheep production was influenced by a number of factors such as educational level, household size, number of sheep sold and sheep price while age was found to adversely affect sheep production in the study area. Farmers require to be trained on sheep production and necessary methods required for sheep production as to increase percent received extension services many (58 percent) of respondents were not satisfied with the services they received. In order to run the regression, diagnostic checks were done to check if multicollinearity existed in the variables. Linear multiple regression analysis results indicate that sheep production contributes to household income and welfare. However, household sheep production was influenced by a number of factors such as educational level, household size, number of sheep sold and sheep price while age was found to adversely affect sheep production in the study area. Farmers require to be trained on sheep production and necessary methods required for sheep production as to increase their household income and welfare through the improvement of the factors that affected sheep significantly. Also since the farmers were exposed on one regime there is a need for extension agents to use more than one extension regime to improve production.

- Description: The use of fire in rangeland has become standard practice for decades; however, there is no shared understanding of how fire affects soil properties. The exact relationship between fire and soil properties is still yet to be understood. The differences in fire frequency, fire intensity, fire severity, the period between fire and sampling resulted in contradictory results amongst studies. A long-term trial at the University of Fort Hare provides a valuable experimental layout for fire research. The trial was established in 1980 with the aim of investigating the effect of burning frequency on vegetation species composition and biomass production. The objective of this study was however to determine the effect of fire management on soil chemical and physical properties under the long-term burning experiment. The treatments of the study site were: no burn (K), annual (B1), biennial (B2), triennial (B3), quadrennial (B4) and sexennial (B6) burns. A line intercept sampling technique was used to collect the soil samples from the surface (0 to 75 mm) for both chemical and physical analysis. All Burning treatments significantly (p < 0.05) increased the bulk density (Db), soil pH, total cations, Magnesium (Mg) and Calcium (Ca), but reduced the soil porosity and exchangeable acidity when compared to the control. Hydraulic conductivity (Ks), water conducting macroporosity (WCM) and total nitrogen were reduced under more frequent burning treatments (B1, B2), as compared to less frequent burning treatments (B3, B4, B6). The aggregate stability showed an opposite trend. Total organic carbon (TOC) was reduced only under annual burning treatment. Burning frequencies did not impact the extractable Phosphorus (p), Potassium (K), Sodium, soil water repellency and water content significantly (P > 0.05). The risk associated with annual burning showed in this study might facilitate processes such as overflow that lead to soil degradation. Triennial burning in rangeland ecosystem supports soil conservation practices. Further studies that measure the quality of rangeland in triennial burning is necessary.

- Description: The South African stock market has become a major player in the African Securities Exchanges Association through its performance. Gold is one of the commodities that are traded at Johannesburg Stock Exchange, hence gold price fluctuations are the crucial factor that JSE needs to keep its eye on. The demand for gold in South Africa is continuously rising because gold has full security, less credit risk and is a highly liquid instrument. Based on the given background, the study examines the effect of gold price volatility on stock market returns in South Africa, employing the Generalised Autoregressive Conditional Heteroskedasticity (GARCH) (1.1) model. The study used monthly data covering the period from 2005 to 2017. The Storage model and discounted cash flows model which are the theories that connect gold price and stock market were specified. The research findings are supported by previous studies. The gold price volatility was found to have a negative effect on stock market returns, and the proxy of stock market returns is the All Share Index. The study will help to provide an understanding of how gold price volatility affects the stock market that will help policymakers to come up with policies that are relevant to volatility of gold price towards stock market.

- Description: Low soil fertility has been identified to be among the major causes of low pasture quantity and quality. Scarcity of high quality forage mainly during the dry season threatens animal productivity in some areas of South Africa, thus the need for identifying livestock feed alternatives. Pigeon pea is a woody legume that has continually been an important shrub in agroforestry and can provide protein-rich livestock feed during times of shortage. Soil fertility to support the production of pigeon pea can be enhanced by application of fertilisers. Therefore, this study was carried out firstly, to determine the effect of phosphorus fertiliser on the growth performance and biomass production of three pigeon pea varieties, and secondly, to investigate the influence of phosphorus application on the nutrient and anti-nutrient content of three pigeon pea varieties. The field experiment was done at the University of Fort Hare research farm in Alice, South Africa. The factors investigated were three pigeon pea varieties namely Chitedze 1, Chitedze 2 and CIMMYT 1 and three phosphorus fertiliser application rates of 0, 40 and 60 kg P/ha. The study was a 3× 3 factorial experiment set up in a randomised complete block design and was replicated three times. The growth performance attributes evaluated in this study include the number of branches, plant height and root collar diameter. Root collar diameter was not significantly (p>0.05) different among the pigeon pea varieties and phosphorus levels. Likewise, the application of phosphorus was not significant (p>0.05) on plant height and the number of branches of all the varieties. However, when P level was varied, there were significant differences among the varieties, and so were the interaction (p<0.05) between variety and phosphorus on plant height and the number of branches. There was no significant (p>0.05) difference among the phosphorus levels on the fresh leaf yield of Chitedze 1 and Chitedze 2, but phosphorus application at 40 kg P/ha increased the fresh leaf yield of CIMMYT 1. Phosphorus application at 60 kg P/ha increased (p<0.05) the dry matter content of Chitedze 1 and Chitedze 2. Furthermore, the results of the trial show that the application of 40 kg P/ha and 60 kg P/ha increased (p<0.05) the dry matter yield of the varieties CIMMYT 1 and Chitedze 2, respectively. The effects of phosphorus application on the nutrient composition of the three pigeon pea varieties varied. The composition of hemicellulose of all the varieties was significantly (p<0.05) increased by the application of 40 kg P/ha. Conversely, the concentration of crude protein, phosphorus, copper and iron, and the calcium to phosphorus ratio of all the pigeon pea varieties was not significantly (p>0.05) affected by phosphorus application and there was no interactive effect of variety and phosphorus. The proximate compositions of fat, total non-structural carbohydrates, ash, neutral detergent fibre, acid detergent fibre, cellulose, neutral detergent insoluble nitrogen, acid detergent insoluble nitrogen of the pigeon pea varieties varied significantly (p<0.05) at different phosphorus application levels. There was an interactive (p<0.05) effect of variety and the level of phosphorus on the concentration of calcium (Ca), potassium (K), magnesium (Mg), sodium, zinc, manganese, and the K/(Ca+Mg) ratio. The digestible dry matter, dry matter intake and the relative feed value were significantly (p<0.05) different among the pigeon pea varieties at varying phosphorus levels. The anti-nutrient composition of Chitedze 2 was not significantly (p>0.05) affected by phosphorus application but the concentration of phenols and saponins of Chitedze 1 was significantly (p<0.05) increased when 60 kg P/ha was applied, but these anti-nutrients were reduced (p<0.05) for CIMMYT 1 at 60 kg P/ha. It can be concluded that phosphorus application influences the biomass production and chemical composition while the optimum phosphorus level vary among the pigeon pea varieties.

- Description: The study investigated the effects of quantitative feed restriction on growth performance, carcass characteristics, internal organs, breast muscle pH and meat colour in broiler chickens. A total of 90, un-sexed, day-old broiler chicks were procured from an accredited supplier and were used for the current trial. For the first 14 days, all birds were brooded in one house and subjected to a uniform day-to-day management. Water was supplied throughout the trial, whereas, feed was only supplied ad libitum between days 1-14 and 29-35 days in feed restricted birds. Feed phases included starter (1-14 days), grower (15-28) and finisher (29-35), respectively. On day 15, birds were randomly allocated to three treatments; each treatment was replicated three times with 10 birds per replicate. The first treatment (T1) group, which acted as control group, was ad libitum feeding for the whole trial duration (1-35 days). For treatments 2 (T2) and 3(T3), 85 percent and 70 percent of the Cobb 500 broiler feed intake standards were applied for a period of 14 days (days 15-28), respectively. Average daily feed intake (ADFI) was determined daily and then average body weight (ABW) was determined weekly. Feed conversion ratio and average daily weight gain was thus computed for each experimental unit (replicate). On day 35, broiler birds were electrically stunned and slaughtered by a sharp knife and then hung for complete bleeding. Data collected included slaughter, carcass, breast, thigh, wing, drumstick, feet, head, spleen, heart, gizzard, intestines (small & large) and liver weights. Breast muscle was further used for the determination of colour (L*, b* and a*), initial (pHi) and ultimate breast pH (pHu) measurements. Although, quantitative feed restriction (T2 & T3) significantly affected growth performance in weeks 3 and 4, birds submitted to T2 performed similar (P>0.05) to control in the final stage, whilst birds in T3 was the poorest (P<0.05). Furthermore, birds subjected to T2 showed no differences of edible carcass portions to the control, however, T3 group showed lower (P<0.05) slaughter and wing weights. Breast ultimate pH values of birds under T2 were similar to control, but birds in T3 had significantly higher (P<0.05) values. Birds under T2 had less (P<0.05) reddish breast meat colour than control at 45 minutes. At 24 hours post-mortem, birds in T3 had lower (P<0.05) lightness values and birds submitted to T2 had higher (P<0.05) yellowness values. Liver weight was significantly lower in birds under T3 and higher (P<0.05) gizzard weights were found in birds subjected to T2. Birds under T2 performed similar to control and were able to compensate for the weight loss when high plane of feed was re-introduced. It can be concluded from the results that restricting 15 percent of feed from Cobb 500 standard feed intake had moderately affected broiler performance. Moreover, restricting 15percent of feed significantly reduced feed intake in broiler chicken.

- Description: Orientation: The manner in which Small, Medium and Micro Enterprises (SMMEs) perform is important for the sustainability of the enterprise. The role of strategic leadership on competitive advantage and innovation performance are investigated within this. Research purpose: To determine whether strategic leadership has an effect on competitive advantage and innovation performance in SMMEs. Secondly, to determine if innovation performance has an effect on competitive advantage. Motivation for the study: Contradictory views still exist on the concept of strategic leadership and its effect on competitive advantage and innovation performance and the effect of innovation performance on competitive advantage in SMMEs. This study contributes to these views within the South African SMME context. Research design, approach and method: A cross-sectional survey design was used and a questionnaire self-administered to a sample of 275 SMMEs in the Buffalo City Metropolitan Municipality drawn through simple random sampling from a population 950 SMMEs available from the Eastern Cape Development Corporation (ECDC) database. Main findings: The result showed that strategic leadership have a positive effect on competitive advantage and innovation performance in SMMEs. Furthermore, the results showed that there is a positive effect of innovation performance on competitive advantage in SMMEs. Practical implications: More is needed to develop strategic leadership. This can be done through leadership training and development, support from government of leaders of SMMEs and finally, a leader can take personal efforts to acquire competencies that allow them to make better decisions in managing the small business. Contribution: The study advances theory on leadership by showing its role on competitive advantage and innovation performance.

- Description: Simulation affords the student a safe and supportive environment in which to practise skills repeatedly without causing any harm to a real patient. The Department of Nursing Sciences at the University of Fort Hare has a laboratory that offers lowto medium-fidelity simulation in the form of task trainers and mannequins. These task trainers and mannequins are used in general nursing, and in community and midwifery nursing sciences, for the demonstration of skills, the practising of skills by students and for formative assessments. In midwifery, task trainers are used for vaginal examinations, abdominal palpation breech and vaginal deliveries and the management of post-partum haemorrhage (PPH). Given that in a real-life clinical environment limited opportunities exist for students to practise during an obstetrical emergency, medium-fidelity simulation (MFS) in midwifery ideally positions the student in a practical environment without risking the patient’s safety. Despite the availability of MFS at UFH, its benefit on the clinical readiness of student midwives is not known. The present study was designed to assess the effectiveness of MFS in enhancing the clinical readiness of student midwives at the University of Fort Hare. The main research objective of the study was to explore, describe and analyse the effect of medium-fidelity simulation on student midwives’ confidence, critical thinking ability, communication, satisfaction and team work in an obstetrical clinical emergency environment. This was a qualitative, interpretive, phenomenological analysis designed to explore the student midwives’ lived experiences regarding the effectiveness of mediumfidelity simulation and the effect of these experiences on clinical readiness. The target population was fourth-year Bachelor of nursing student midwives at the University of Fort Hare. Purposive sampling was used to select five student midwives who were team leaders during the management of PPH using MFS. Ethical approval was granted by the University of Fort Hare Ethics Committee. Informed consent was obtained from the participants prior to data collection. Trustworthiness was ensured by observing the principles of transferability, credibility, confirmability and dependability. Data was collected through individual face-to-face interviews and a semi-structured interview guide. All fourth-year student midwives had viewed an on-line video entitled Essential Steps in Management of Obstetrical Emergency(ESMOE) Postpartum Haemorrhage, in which the procedure was demonstrated. The video, sent via Backboard, was presented in such a way that student midwives had the opportunity to watch it repeatedly in order to thoroughly comprehend the demonstrated skill. A semi-structured interview guide was used for data collection. Interviews were conducted in the simulation laboratory. A Samsung smartphone was used to record interviews and a notepad was used to make notes of gestures, such as smiles or other facial expressions. Data was analysed using thematic content analysis applicable to interpretative phenomenological analysis (IPA) studies using the six steps: reading and re-reading; initial noting taking; developing emergent themes; searching for connections across the emergent themes; moving to the next case and lastly, looking for patterns across cases. The major findings indicated that the participants had differing views regarding the concept of clinical readiness; some held that clinical readiness meant being ready or prepared to handle any eventuality in the course of work, others opined that it was a state of being conversant with the policies and procedures in the clinical ward. Participants believed that clinical readiness was parallel to being competent and that midwives should always be ready to anticipate complications that might arise with the patient, endeavouring to analyse and interpret such conditions clinically. Participants expressed the need to see the simulation skill demonstrated repeatedly for thorough understanding of the technique, so that they could work independently in an obstetrical emergency situation. During simulation, participants were confident in delegating duties to team members, affirming that in order to ensure that tasks were carried out, team leaders should receive regular updates from team members.

- Description: The study sought to assess the effects of municipal demarcation board decisions on health care services. Since the democratic elections, the South African government was faced with the task of eliminating the racially based municipal system that segregated certain groups of people in service delivery. To deal with the determination and re-determination of municipal boundaries the Municipal Demarcation Board (MBD) was established in 1998. The study used secondary data to achieve its objectives. A number of official documents and sources that were used for this study. These included government documents, municipal documents, NGO documents, private sector documents. Results showed that municipal revenue is negatively affected by demarcations. Alfred Nzo District Municipality is no exception to this. Furthermore, demarcation processes have implications for health human resources and other municipal health processes. Human resources such as nurses and doctors are sometimes shifted from one municipality to another. Other negative consequences (especially in the transition period) may result from issues related to the supply chain, long-term contracts, municipal plans and policies, financial and other systems, information and databases, asset registers and asset maintenance, and repairs.

- Description: Although the single-parent family is becoming an increasingly common family structure, it is associated with a great many hardships. Owing to the heavy responsibilities which fall on single parents, most fail to meet all of the needs of their children, particularly with respect to the financial needs which are entailed by providing educational necessities, safe, stable and permanent accommodation, adequate food and nutrition and healthcare. This study adopted the parental loss perspective, the economic hardship perspective and the interparental conflict perspective in investigating the experiences of young adults who were raised in single-parent families. A qualitative approach was adopted to conduct the research and data was collected from 26 male and female participants between the ages of 22 and 39 years who resided within the Raymond Mhlaba Local Municipality. The researcher sought permission to conduct this study from all the community leaders including the councillors and chiefs, thereby acquiring the first referrals. The study made use of purposive sampling and snowballing to select the research sample. The data was collected by using semi-structured interviews and focus group discussions and analysed through the use of thematic analysis. The principal findings of the study indicate that although children who are raised in single-parent homes can attain high levels of education and have solid functional relationships in later life, a lack of finance and active parental involvement in their educational activities and social lives can serve to limit their development. As single-mother households face more economic hardships than any other family structures, financial assistance from both the government and their communities would undoubtedly increase the likelihood of children in single-mother families attaining their true academic potential. In addition, free counselling services would also help children who are forced to live under these circumstances overcome the emotional burden which inevitably accompanies either losing or being separated from one parent.

- Description: The Autoregressive Distributed Lag model was used to estimate and analyse the relationship between crude oil prices and the trade balance of South Africa. This study estimated the trade balance model and analysed the relationship between crude oil prices and the trade balance of South Africa from the period 1990 to 2015. The bounds cointegration test confirmed the existence of a long-run relationship between the trade balance and real oil prices, real effective exchange rate, domestic income, real interest rate and the inflation rate. The results confirm that changes in oil prices have a negative impact on the trade balance whereas, currency devaluation, real interest, inflation rate and domestic income had a positive effect on the trade balance. The negative sign and significance of the Error Correction Term and diagnostic tests confirmed the reliability of the results.

- Description: This study explores the impact of post-apartheid agricultural changes on citrus farmers in the Peddie area. The case study focused on the Craighead Citrus Farm at Kwatho as well as the Naudeshoek Citrus Farm, Ripplemead Citrus Farm and Siyamila Citrus Farm in the Balteni area. The study considered the effect of agricultural changes on citrus production, productivity of the farms in question, as well as the impact on poverty alleviation in Peddie District. In the study, the challenges encountered by both farmers and communities due to the agricultural changes in the new democratic dispensation were also considered. The study further considered the role played by the Department of Agriculture and Ngqushwa Local Municipality in assisting these farmers to increase citrus production in order to create employment opportunities. To achieve these objectives, a review of literature and collection of evidence in the form of interviews, and observations were conducted in the research areas. The research findings indicated that the Craighead Citrus Farms is state owned land, which belonged to Ulimocor, a parastatal under the former homeland government (Ciskei). This farm is no longer operational and is abandoned. During the period of this study the Naudeshoek Citrus Farm, Ripplemead Citrus Farm and Siyamila Citrus Farm were operational and progressing. Citrus farming in this area has potential to boost the economy, which would only be possible with the establishment of partnerships between the emerging farmers, government, commercial farmers and Ngqushwa Local Municipality.

- Description: This study was conducted to investigate the influence of degradation on vegetation and soil quality in two semi-arid rangelands in the Eastern Cape Province of South Africa. The study was undertaken in Kwezana and Esigingqini communal areas that showed signs id degradation. The assessment incorporated the soil and grass layer in different degradation levels, namely nondegraded, slightly degraded, moderately and severely degraded. The non-degraded has a sufficient amount of vegetation cover and species composition. The slightly degraded site consists of a few visible bare patches. The moderately degraded areas showed signs of active sheet erosion such as pedestals and a higher percentage of bare areas and the severely degraded area is characterized by dongas and gullies, with vast areas that have no ground cover or top fertile soil layer. Using a step point method, herbaceous species composition was determined within three transects from three plots 100 m x 40 m in each degradation level. The aboveground phytomass production was determined by harvesting herbaceous species within four randomly placed 0.25 m2 quadrats in each transect. Bare ground was determined by counting and recording the distance between tufts within each quadrat. Litter cover was determined by visual observation and rated on a scale of 1 to 5. A number of physical and chemical soil properties were used to quantify the effects of degradation on soil quality. To determine soil chemical properties, three soil samples were collected at a depth of 20 cm, in each plot and analyzed for pH, soil macro (N, C, K, P, Ca, Mg) and micro (Zn, Fe, Mn and Cu) nutrients. Soil compaction was determined using a soil pocket penetrometer. Readings were taken at 5 mm from 30 points placed at 1 m intervals and distributed in a randomly established straight line in each plot. Soil loss was determined using a rainfall simulator. Splash cups were filled with soil and placed under the rainfall simulator for 8 minutes per rainstorm at 360 mm-1 intensity. Results showed that at Esigingqini a total of 20 herbaceous species were identified, 17 of which were grasses. About 60percent of the identified grasses were Increaser II species, 15percent were Increaser II and 25percent Decreasers. In terms of palatability, 50percent of the grass species had poor palatability and the remaining had either average or high palatability. At Kwezana, 18 herbaceous species were identified of which 28percent were Decreasers and 61percent were Increaser II species. Half of the species had low palatability and only 28percent had high palatability. In both communal areas, litter cover was highest (P < 0.05) in the non-degraded areas followed by the slightly degraded sites and this was to be expected. Similarly, in both communal areas, there was a shift in species composition of decreasers and perennial grasses being replaced by annual species of poor quality and low palatability as the degradation levels increased. Results on soil chemical properties showed that the non-degraded areas had higher (P < 0.05) pH levels (8.5) than the severely degraded soils (5). A similar trend following a degradation gradient was observed for some soil nutrients such as N, P or Mg. Both the macro and micro nutrient concentrations were relatively higher (P < 0.05) in summer than in winter in both communal areas. Results on physical properties showed that soil loss and compaction were relatively lower (P <0.05) in the slightly degraded and non-degraded sites and increased with severity of degradation. In both communal areas, the severely degraded areas lost soil up to 1.1 t ha-1 due to degradation and the non-degraded areas had a soil loss of less than 0.8 t ha-1. The rate of soil loss between the severely and non-degraded areas is significantly different. The differences may be attributed to the differences in the vegetation cover which influences the rate of erosion on the various degradation gradients. These results suggest that both the grass layer and soil quality is negatively affected by degradation. Therefore, there is a need for land use practices that promote the sustainable use of rangeland resources. Such practices may include rotational grazing, reseeding, veld resting and fire. Measures to control the consequences of degradation and rehabilitate these deteriorated rangelands must be a priority.

- Description: All over the world many rural households are engaged in different economic activities to sustain their livelihoods. To a large extent, a household’s ability to do this depends on access to basic assets such as infrastructure, social, human, finance or physical. Access to these assets can be affected by large projects such as road construction which can either enhance or hinder access to key assets. The main objective of the study is to investigate the impact of the construction of the N2 Wild Coast Highway in the Eastern Cape Province on the livelihoods of rural households in the Nyandeni local municipality. The study also seeks to investigate the dominant household economic activities within the municipality, factors affecting the choice of these activities and the probable impact of the construction of the N2 highway on these economic activities and livelihood strategies. The road construction is translated as a ‘shock’ in the livelihood context, hence the study further seeks to document how households respond to road construction ‘shock’ to their livelihoods, based on the findings of the study. The study applied a mixed methods approach, applying both qualitative and quantitative data. Two sources of data are used; a survey of 40 households in the Nyandeni local municipality which provided the qualitative data and survey data from the PSPPD-II quantitative data from project conducted by the Economics department at the University of Fort Hare, which provided the quantitative data. The multinomial logistic regression was used to determine the livelihood strategies used as well as the related determinants. The results showed that financial, social and physical capitals are key assets that support livelihoods in Nyandeni municipality, which were highly determined by the deprivation score, social grants and community networks. To get a clearer understanding of the underlying effects of the road construction, focus prompts interviews were also conducted. These were analysed using thematic analysis. The results showed that the road construction had both the negative and positive effects. The positive effects included better links to social facilities such as hospitals and schools as well as neighbouring municipalities. The construction also created employment for construction workers. In addition, the construction company helped households whose houses were destroyed near the road to build better houses. Although the households complained of danger from high speed vehicles because of better roads, they also indicated that the speed bumps in some areas led to an improvement in well-being especially for school children. The negative effects included destruction of burial grounds as well as the weakening of housing structures due to blasting. Further, some vegetation which was used by households as a source of livelihood was destroyed during road construction. In some cases, social capital assets were also disturbed as a result of the displacement that occurred in the process. Responses by households have been mixed, with some households taking advantage of increased access to markets as well as finances to find alternative sources of livelihoods. Households that responded negatively constantly seek out reimbursement from the government and construction company without much success.
