- Description: BACKGROUND Despite the adverse outcomes associated with traditional male circumcision, the practice remains prevalent, especially in the Eastern Cape, South, Africa. This study seeks to assess the practices of traditional surgeons and nurses in relation to the prevention and control of infections and their understanding of human physiological mechanisms during circumcision processes. METHOD This study has adopted a qualitative design, which involved conducting 115 semistructured interviews among traditional surgeons, traditional nurses and traditionally circumcised men, and one focus group discussion among traditional nurses. The data generated were transcribed and subjected to thematic content analysis. RESULTS The analysis revealed that both traditional surgeons and nurses demonstrated both poor aseptic techniques and a lack of knowledge of how the human body functions. Their lack of knowledge of basic human physiology meant that they trivialised sepsis in the penile wound. In addition, the seclusion lodges for circumcision and initiates living were unclean and uninhabitable. CONCLUSION The poor aseptic techniques of traditional surgeons and nurses, as well as the uncleanliness of their environment during traditional male circumcision procedures, could expose initiates to infections and morbidity. Environmental health officers should regularly supervise traditional surgeons and nurses in order to prevent the adverse health outcomes associated with the traditional male circumcision practice.

- Description: Land reform, as enshrined in the constitution of the Republic of South Africa, aims to foster conditions which enable citizens to gain access to land on equitable basis. Section 25(6) of the constitution states that ‘a person or community whose tenure of land is legally insecure as a result of past racially discriminatory laws or practice is entitled, to the extent provided by an Act of Parliament, either to tenure, which is legally secure, or comparable redress. In addition, section 25(7) states that a person or community dispossessed of property after 19 June 1913 as a result of past racially discriminatory laws or practices is entitled to the extent provided by an Act of Parliament, either to restitution of that property or to equitable redress. Within this context, this study assessed the impact of land reform on the livelihoods of subsistence farmers in Great Kei Local Municipality. The study adopted a qualitative approach in order to get an in-depth understanding of the farming activities of land reform beneficiaries, the contribution of farming activities to agro-based sustainable livelihoods and the general challenges faced by subsistence farmers. The sample comprised of thirty (30) farmers, two focus group discussions which comprised of six (6) farmers each and five key informants from the Department of Rural development and Agrarian Reform, a councillor and a community leader from the local municipality. The study found that most farmers who were allocated land were from different disadvantaged backgrounds. Many of the farmers came from farming backgrounds hence they had the requisite skills and knowledge. Those with relatively limited knowledge and skills were technically supported and subsequently improved their production and livelihoods. Those farmers that were trained in various farming aspects did well as they improved production. However, it was found that those farmers that did not receive training and adequate support yielded negative results in both crop and animal production. Drought has been another major contributor in the decline of the production. It was also found that the post settlement grants, such as Comprehensive Agricultural Support Programme and Recapitalization and Agricultural Development, are not enough and regular for infrastructural development on the farms.

- Description: Unintended pregnancy remains a public health concern worldwide despite the availability of many contraceptives options. The South Africa Government introduced Implanon —a Long-acting Reversible Device— with aim to cost effectively prevent unplanned pregnancy. There are concerns that the implementation of this contraceptive option was without prior piloting to test for level of acceptance and attitude towards this contraception. Also, there is paucity of evidence on knowledge of women and their attitude to implanon as well as duration of use and reasons for discontinuation of implanon in South Africa. The present study address this gap by assessing the women’s knowledge of and attitude to implanon as well as reasons for implanon discontinuation in Buffalo City Municipality in South Africa. This prospective observational study administered a pre-validated questionnaire to 189 women who had removed implanon in the reproductive health clinic in one regional hospital and a primary health centre in Buffalo City Municipality. Descriptive statistics were used to analysis the study data. The average duration for implanon use among the participants was 11.2 months. Most participants had poor knowledge of implanon and implanon knowledge was significantly associated was with age. Most participants opined that implanon use is associated with heavy bleeding (60.7), irregular frequent bleeding (84.3percent), and weight gain (67percent). The main reason for implanon discontinuation was its side effects (71.3 percent). Other reasons for discontinuation of implanon are poor or wrong positioning (3.2percent), want to become pregnant (4.3percent). Some participants discontinued implanon because they were on treatment; 24 participants on ARV drug, one on antipsychotic drugs, and one on TB drugs. Experience of heavy bleeding (39.9percent) was the most stated side of implanon leading to implanon discontinuation. The study concluded that women, even though adopted implanon, lack knowledge of implanon mechanism of action and side effects. Poor knowledge of implanon side effects could explain its early discontinuation among women in South Africa. Provider should prioritise comprehensive counselling of clients on implanon side effects and mechanism of action in order to realise the benefit of implanon in this population.

- Description: The purpose of this study was to investigate the relationship between the concept of clean audit reports in relation to service delivery. The study was conducted in the Amathole District Municipality in the Eastern Cape Province and centred on the audit outcome of the municipality for the 2013/2014 financial year. A qualitative research design was adopted in order to conduct the study and the data was collected through the conducting of semi-structured interviews. The research sample comprised officers who were employed by the Amathole District Municipality and one manager from the office of the Auditor-General. The key findings of the study revealed that, at present, the concept of a clean audit outcome is used by municipal officers to imply that the performance of an organisation is to be assessed mainly on the basis of evidence which is provided by financial indicators, to the exclusion of non-financial benchmarks. This assumption tends to encourage municipal officers to strive towards impressing auditors, rather than serving their communities through the providing of adequate service delivery. In addition, the auditing of municipalities does not assess their performance in relation to service delivery and the ways in which communities at the local level are affected by it. At present it appears to be beyond the remit of auditors to investigate the validity of the protests which erupt in communities in response to poor service delivery or whether the members of communities and other affected stakeholders are satisfied or dissatisfied with the manner in which services are rendered by their municipalities. Consequently, those who are tasked with the making of decisions in municipalities act upon the recommendations which are made in their audit outcomes and formulate plans in relation to service delivery or projects which do not necessarily accord with the needs of the communities which they are intended to serve. Consequently, on the basis of the findings of this study, it is proposed that assessments of the performance of organisations should incorporate non-financial indicators into the auditing process. Adopting this approach would minimise incidences of municipalities receiving clean audit outcomes while the members of the communities which they serve take to the streets to express their anger and frustration as a result of poor service delivery.

- Description: Background: Cholera is an acute infectious disease of the small intestine caused by the bacterium called Vibrio cholerae, which has two serogroups01and 0139which is also known as choleragenic V. cholerae. This disease is characterized by profuse watery diarrhoea and severe dehydration which can lead to death of both adult and children if treatment is not promptly given. Cholera is spread through ingestion of V. cholera contaminated water and food. Cholera has displayed global presence more than seven times and caused tremendous disaster to humankind. Method: This was a retrospective study among patients with cholera within the period of ten years (2005 to 2015) and the total number of patients was 106. The target population for this study were patients at Raymond Mhlaba Local Municipality who attended Victoria hospital and were diagnosed with Vibrio cholerae species with respect to sources of water and non-water sources during the mentioned period. A multivariate Logistic regression was used to determine the risk factors of cholera and comparison was made in the treatment of cholera outcomes for factors which were statistically significant at P < 0.05. Results: The median age was 24.5 (IQR: 7.0-44.8) for all respondents with cholera. Patients within the age range of 26-40 and 41-55 were found to have a higher risk of cholera (2.20, 95percent CI: 1.51, 4.22) and (1.13, 95percent CI: 0.61, 2.01) respectively. The risk of cholera was considerably higher among the black race (2.51, 95percent CI: 1.52, 4.31) compared to the coloured (1.33, 95percent CI: 0.75, 3.713). Patients who used source of water supply from carrier/Tanker and Dam/River had higher increased risk of contracting cholera (1.71, 95percent CI: 0.92, 3.62) and (2.61, 95percent CI: 1.38, 4.25) respectively compared to patients that used other sources of water. Home, party and restaurant as places patients had eaten 24 hours earlier before the onset of cholera were associated with increased risk of severe cholera. Patients who shared toilet facilities had increased risk of cholera (0.91, 95percent CI: 0.47, 1.62) compared to the ones who used private toilet. Those patients who did not practice hand washing had an increased risk of contracting cholera (1.45, 95percent CI: 0.88, 2.12) compared to the ones who washed their hands. When Logistic regression was carried out, the following risk factors were found to be statistically significant in causing cholera at 5percent significance level; Age ( 26-40), gender, level of education, marital status, sources of water supply, place eaten in the last 24 hours before onset of cholera, type of toilet used and hand washing. Conclusion: Improvement in level of education, sources of water supply, place of last eaten before cholera sickness, toilet facilities, hand washing practices are key risk factors for cholera disease and hospitalization among patients in Raymond Mhlaba local Municipality, Eastern Cape. The strong association between water and sanitation highlights the need for a more thorough assessment of potential waterborne exposures and the risk faced by family members suffering from cholera infection cases and may warrant renewed research regarding the use of targeted chemoprophylaxis in endemic rural settings.

- Description: This study aimed to investigate the feeding behaviour of the calanoid copepod, Pseudodiaptomus hessei, particularly whether it prefers to feed on a planktonic or benthic food source. The effect of different microalgae species on the feeding preference, ingestion, and gut evacuation rate were investigated. Two microalgae species (Isochrysis galbana and Tetraselmis suecica) were used, to test gut fullness and gut evacuation of P. hessei. The copepods were starved for 6 h and allowed to feed on monalgae diets, I .galbana and T. suecica, and a 1:1 binary diet mixture of T. suecica and I. galbana. The gut fullness and gut evacuation rates were determined by observing under the dissecting microscope and gut content percentage was recorded (as 0, 25, 50, 75 or 100 percent) along with copepod sex. Copepods that feed on T. suecica fill their gut after 30 min, while those that feed on I. galbana do so after 40 min. There was a significant difference (p= 0.02) between sexes with males filling their gut faster than females. However, copepods that fed on I. galbana evacuated their gut content completely after 30 min, while those fed on T suecica evacuated theirs after 40 min. There was no difference between males and females for gut evacuation. Even though there was high gut fullness rate when P. hessei was feeding on T. suecica, I. galbana is recommended as the best mono-algae diet to culture P. hessei. The feeding behaviour of P. hessei was investigated, as to whether it prefers to feed on a planktonic or benthic food source. Copepods were starved for 3 h and then allowed to feed on two microalgae species (I. galbana and T. suecica), one presented as a benthic and other as planktonic. Controls included swapping the modes of presentation for each algae species. Ingested microalgae species were quantified using real-time PCR, with threshold cycles interpreted as relative abundance ratio (planktonic microalgae divided by benthic microalgae species). Pseudodiaptomus hessei preferred to feed on planktonic food sources initially as there was a difference between planktonic and benthic ingested food (p=0.026). Copepods shifted from planktonic to benthic food sources after 80 min of feeding planktonically. Planktonic food sources were the preferred choice for P. hessei regardless of microalgae species offered. The results from this study also confirm that P. hessei feed on a benthic food source during the day under culture conditions. This information can be used as baseline information for aquaculturists to rear the species as live feed for marine fish larvae.

- Description: DNA barcoding is a molecular technique that uses a short DNA sequence for species identification. It harnesses global community efforts to establish large-scale public reference libraries to allow species identification. Red algae are a complex group of species and are difficult to identify on morphological grounds only. Red algae have the highest production of halogenated compounds, and are used in the medical and pharmaceutical industries. This study therefore aimed at developing DNA barcodes, universal primers and a Kenton-on-Sea red algae species list, which will aid as a baseline for red algae biodiversity and conservation research. A potential DNA barcode region was designed from the rbcL gene, because rbcL is easy to amplify, easy to sequence and it can differentiate organisms to species level. Primers were designed from multiple red algae rbcL sequences and they were evaluated using bioinformatics tools. Red algae from the Algoa Bay region were screened with these primers and a 77% PCR amplification success was obtained. The PCR products were sequenced and 96% of the amplicons were successfully sequenced and resulted in a barcode sequence length above 700bp, which could be used to identify red algae species. Twenty-six (26) red algae species from Kenton-on-Sea, near Algoa Bay, were successfully identified using the Barcode sequence amplified from a primer set developed from the rbcL gene and were uploaded on the BOLD database for public access. This barcode is, therefore, suitable for use by the South African National Biodiversity Institute or other marine researchers, to identify South African red algae species and ensure the maintenance of their biodiversity and conservation.

This study therefore aimed at developing DNA barcodes, universal primers and a Kenton-on-Sea red algae species list, which will aid as a baseline for red algae biodiversity and conservation research. A potential DNA barcode region was designed from the rbcL gene, because rbcL is easy to amplify, easy to sequence and it can differentiate organisms to species level. Primers were designed from multiple red algae rbcL sequences and they were evaluated using bioinformatics tools. Red algae from the Algoa Bay region were screened with these primers and a 77% PCR amplification success was obtained. The PCR products were sequenced and 96% of the amplicons were successfully sequenced and resulted in a barcode sequence length above 700bp, which could be used to identify red algae species. Twenty-six (26) red algae species from Kenton-on-Sea, near Algoa Bay, were successfully identified using the Barcode sequence amplified from a primer set developed from the rbcL gene and were uploaded on the BOLD database for public access. This barcode is, therefore, suitable for use by the South African National Biodiversity Institute or other marine researchers, to identify South African red algae species and ensure the maintenance of their biodiversity and conservation.

- Description: Land degradation is a serious problem that many poor communities face and this worsens their vulnerability and therefore, poses a threat to food security, as it reduces yield, forces farmers to use more inputs, and disproportionately affect the smallholder farmers in remote communities that also suffer diverse infrastructure disadvantages. In response to that, the international development agencies, donors, and Non-Governmental Organizations (NGOs), especially faith-based organizations have turned towards sustainable farming approaches. Much attention has been paid to a combination of sustainable farming measures which are packaged under the “Conservation Agriculture” (CA) banner. The previous work in the KZN Province and elsewhere has demonstrated that CA has the potential to improve the soil structure, thereby reversing the effect of soil degradation. Consequently, many of the farmers in the areas in which these demonstrations have been conducted appreciate the ecological and economic value of adopting CA. However, the on-farm financial benefits of adopting a CA specific tillage practice are not as well known or thought to be as pronounced. By means of integrating field survey, reviewed literature, and econometric analysis, this study assessed the farm level cost-benefit analysis of conservation agriculture for smallholder maize farmers in OLM, specifically in one demonstration village of Bergville town. The analysis is based on the case study of the NGO’s work in which they had selected a community and participating households who received assistance in a number of ways such as maize seed, soil preparation, and CA planters. To analyse the farm level cost-benefit analysis, descriptive, linear regression, gross margin (GM) and appraisal indicators such as Net Present Value (NPV), Benefit Cost Ratio (BCR) and Internal Rate of Return (IRR) were used. The descriptive analysis, used to analyse the factors affecting the extent of adoption of CA revealed that socio-economic characteristics have the influence on the level to which a farmer responds to incentives. Linear regression model used in this study showed that years in farming, involvement in joint farmer’s group, and use of cover crops have the significant effect on the extent of adoption of CA. Moreover, the calculated gross margins of the two tillage systems were different, revealing higher Gross Margins for CA plots than for conventional plots. The major cause of the difference was found to be differences in the variable costs. When using appraisal indicators (NPV, BCR, and IRR) the study projected a 10-year period at 8% and 10.5% discount rates. The study also revealed positive NPVs for both CA and conventional agriculture. The positive sign implies that there are positive pay-offs for investing in both trial and control plots. However, trial plots have larger NPVs compared to control plots, meaning that there are less additional returns for investing in control plots compared to trial plots. Results also reveal that with 10.5% discount rate, the NPVs are lower than with 8% discount rate, showing that lower discount rates are consistent with higher performance over the long term. This therefore means that at lower discount rate, it is more viable to produce maize using CA than using conventional tillage system. In the case of BRC presented in the study, it was revealed that at both low and high discount rates, the trial plots were more viable than the control plots. Finally, the IRR presented in the study reveal that the trial plots would be able to pay their way much faster than the control plots. Overall, the study found that there are incentives to adoption of CA compared to conventional farming. The message from the different results arising from the use of different discount rates is that farmers should receive assistance at low cost of capital in order for their operations to be viable and this works out well over the long term as shown by the 10-year period projections.

- Description: Sanitary hot water production contributes significantly to the electrical energy consumption in the university campus. An in-depth understanding of the current hot water technology, number of students, capacity of water used per student, time of use of hot water, total volume of hot water consumed and the total energy used on an average weekday in a university residence are very crucial in opting for energy efficient technology like an air source heat pump (ASHP) water heater. The study focused on quantitative and qualitative analysis of data collected for the hot water profiles in one of the university residences (Elitheini 1) from the conduction of experiment and questionnaires. The results revealed that 94% of the 75 students used hot water during the Eskom morning peak and 61% during the Eskom evening peak. In addition, the average daily energy consumption of the 12 kW Calorifier was 139.49 kWh, while the measured volume of hot water usage was 1950 L which is in strong agreement with the total volume (1945 L) of hot water consumption from the questionnaires. The p-value of the average volume of hot water usage measured by experiment and questionnaires was 0.7 and is of no mean significant difference. The monthly energy consumption for the week days was projected to be 2929.31 kWh. By retrofitting of calorifier with an ASHP unit, the energy consumption could reduce to 976.43 kWh based on its consecutive coefficient of performance of 3. Finally, from the energy consumption reduction analysis and the current Eskom tariffs, it can be alluded that the payback period of the proposedASHP unit as a retrofit to the calorifier is going to be less than 2 years and is worthy to invest into such technology under this study due to its favourable payback period and the reliability and lifespan of the ASHP unit.

- Description: This study examined the role of transport infrastructure in attracting foreign direct investment in South Africa. The study used quarterly time series data for the period of 1994 to 2014. The Johansen cointegration and Vector Error Correction Model (VECM) were used to determine the impact of transport infrastructure on foreign direct investment in South Africa. The explanatory variables in this study were market size, transport infrastructure, labour cost, exchange rate and corporate tax. Results from this study showed that market size, transport infrastructure and corporate tax have a positive and significant impact on foreign direct investment, while exchange rate is positive but insignificant, and labour cost has a negative and insignificant impact on foreign direct investment in South Africa. The policy recommendation that comes from this study is that efforts should be made to improve the standard of transport infrastructure in order to enhance and attract more of foreign direct investment. The government should follow policies that will attract foreign direct investment.

- Description: Domestic labour is widely recognized as one of the most vulnerable labour sectors, both nationally and internationally. In South Africa, sectoral determination 7 was specifically developed to protect domestic workers’ rights and provide them with the means to negotiate with and hold employers to account. However, research over the past years has demonstrated that, while some areas of domestic labour have improved, many workers are still locked in exploitative labour relationships. This research shows that it may seem as if there are significant changes in this sector since the introduction of the sectoral determination, but paternalistic orientations, one-of-the-family myths, and food distribution suggest otherwise. The research concluded that continuities of exploitative and discriminatory practices are still prominent in the employment relationship when viewed through the lens of paternalistic care, food distribution, and the ‘one-of-the-family’ myth.

- Description: This study sets out to identify the most effective way in which persistently and unacceptably high levels of inequality can be reduced in South Africa. Three alternative approaches were identified from the literature and their impact explored statistically. They are: the introduction of a ‘Social Solidarity Grant’; a decrease in unemployment by 5%; and a narrowing of the skill premium through an expansion of tertiary education. It is important to note that the study makes no attempt at explaining how these outcomes might be implemented or achieved. Rather, it sets out to determine only the effect that such policies may have on measured inequality. It was found that while the introduction of a new grant had a significant effect on inequality, this effect however, was once-off. The grant would be financed by individuals in the top decile through tax increases, which would be a complicated endeavour. Both job creation and a narrowing of the skills premium were significantly effective in decreasing inequality. The narrowing of the skills premium showed more promise due to its accelerating effectiveness in decreasing inequality over time and the fact that it directly addresses the problem of wage differentials. It was noted that the extreme levels of poverty and unemployment in South Africa may dampen enthusiasm for policies that narrow the skills premium to reduce inequality. These characteristics make job creation a more popular policy option because of the positive impact on poverty and unemployment as well as on inequality.

- Description: It has been shown in ionospheric research that modelling total electron content (TEC) during storm conditions is a big challenge. In this study, mathematical equations were developed to estimate TEC over Sutherland (32.38oS, 20.81oE), during storm conditions, using the Empirical Orthogonal Function (EOF) analysis, combined with regression analysis. TEC was derived from GPS observations and a geomagnetic storm was defined for Dst ≤ -50 nT. The inputs for the model were chosen based on the factors that influence TEC variation, such as diurnal, seasonal, solar and geomagnetic activity variation, and these were represented by hour of the day, day number of the year, F10.7 and A index respectively. The EOF model was developed using GPS TEC data from 1999 to 2013 and tested on different storms. For the model validation (interpolation), three storms were chosen in 2000 (solar maximum period) and three others in 2006 (solar minimum period), while for extrapolation six storms including three in 2014 and three in 2015 were chosen. Before building the model, TEC values for the selected 2000 and 2006 storms were removed from the dataset used to construct the model in order to make the model validation independent on data. A comparison of the observed and modelled TEC showed that the EOF model works well for storms with non-significant ionospheric TEC response and storms that occurred during periods of low solar activity. High correlation coefficients between the observed and modelled TEC were obtained showing that the model covers most of the information contained in the observed TEC. Furthermore, it has been shown that the EOF model developed for a specific station may be used to estimate TEC over other locations within a latitudinal and longitudinal coverage of 8.7o and 10.6o respectively. This is an important result as it reduces the data dimensionality problem for computational purposes. It may therefore not be necessary for regional storm-time TEC modelling to compute TEC data for all the closest GPS receiver stations since most of the needed information can be extracted from measurements at one location.

- Description: Over the years, human trafficking has become one of the fastest growing crimes in the world. According to a report of the United Nations Office on Drugs and Crime, Women and Children account for 75 percent of trafficked victims. Between 2007 and 2010, children accounted for 20 percent of the trafficked victims which is approximately 1343 children per year. Sadly, these statistics continue to rise annually. It is from this premise that no one can doubt the rationale behind the 2015 Immigration Regulations that affect children travelling in and out of South Africa. However, in terms of section 28 (2) of the Constitution of the Republic of South Africa, it is a prerequisite that in any matter affecting a child, the best interest of the child be of paramount importance. This mini dissertation seeks to establish whether these Immigration Regulations which initially came into effect in May 2014, are in the best interest of child travellers. This has been done by looking at the old system which regulated the movement of children; its loopholes and shortcomings, thereby establishing whether Regulation 6 (12) is a panacea or in fact the hallmark of a series of problems that have a detrimental effect on the well-being as well as the rights of the child. The research methodology is mainly based on a study of existing literature. This largely includes internet sources, national legislation, regional and international instruments as well as case law. The South African Immigration Act 2002 is the primary reference with regards to regulatory information. However, lessons are drawn from legislation from other jurisdictions, notably Zimbabwean Immigration laws as well as those of Namibia. This is because South Africa shares a border with Zimbabwe and it also has a historical connection with Namibia and has good relations with both States. The mini dissertation analyses the impact of the 2015 Immigration Regulations not only on children but on other sectors as well. Lastly, the latter makes recommendations on how to improve these Regulations without affecting the best interest of child travellers.

It is from this premise that no one can doubt the rationale behind the 2015 Immigration Regulations that affect children travelling in and out of South Africa. However, in terms of section 28 (2) of the Constitution of the Republic of South Africa, it is a prerequisite that in any matter affecting a child, the best interest of the child be of paramount importance. This mini dissertation seeks to establish whether these Immigration Regulations which initially came into effect in May 2014, are in the best interest of child travellers. This has been done by looking at the old system which regulated the movement of children; its loopholes and shortcomings, thereby establishing whether Regulation 6 (12) is a panacea or in fact the hallmark of a series of problems that have a detrimental effect on the well-being as well as the rights of the child. The research methodology is mainly based on a study of existing literature. This largely includes internet sources, national legislation, regional and international instruments as well as case law. The South African Immigration Act 2002 is the primary reference with regards to regulatory information. However, lessons are drawn from legislation from other jurisdictions, notably Zimbabwean Immigration laws as well as those of Namibia. This is because South Africa shares a border with Zimbabwe and it also has a historical connection with Namibia and has good relations with both States. The mini dissertation analyses the impact of the 2015 Immigration Regulations not only on children but on other sectors as well. Lastly, the latter makes recommendations on how to improve these Regulations without affecting the best interest of child travellers.

- Description: Financial assets, and particularly fiat money, play a critical role in the prosperity of an economy. Its health therefore becomes the cornerstone of an economy, as asserted by modern financial intermediation theory. Fundamentally, as established by literature, crises affect bank balance sheets and subsequently banks’ ability to provide credit, thereby restricting investment, capital and asset growth, aggregate output, and eventually national income. This study conclusively establishes the relationship between financial crises and the South African bank lending activities. It describes this relationship, concluding that crises and bank lending have a negative short run relationship and positive long run relationship. The study gives a brief background of recent crises that were experienced by different economies in the world. The study uses South African quarterly data for the period 1996 to 2015, where it employs a VECM model that gives empirics to the effect that lending is indeed negatively affected by financial crises, but only in the short run. This is due to the South African Reserve Bank, through its monetary policy, cushioning the banking sector against the detrimental effects of economic distress. The study recommends that given the indebtedness of South Africa relative to GDP growth, to avoid credit downgrades and disinvestment in the long run, government should focus on improving GDP growth rather than debt; and should establish a policy framework that centralises operational transactions in order to reduce the effect of crises on real output.

- Description: The international financial environment has become riskier due to the recent developments in product offerings and failure of regulation to keep abreast with these changes. The Global Financial Crisis exposed inadequacies of regulation, thus consensus on the need for comprehensive and uniform regulation was made by G-20 member states. Imposing exchange trading, clearing, reporting and capital requirements on the derivatives market are some of the ways of dealing with the problems caused by lax regulatory oversight. In this study, through the comparative analysis of derivatives regulation in South Africa, Brazil, India and Turkey, it was established that emerging countries are taking active steps to implement the G-20 agreement. Uniformity in the core rules was noted, with differences in the supportive legislation. Country specific rules which support the macroeconomic factors that are faced by these countries and the infrastructure available for regulatory execution are used amongst countries. The study concluded that current regulation in emerging countries is accommodative and regulatory differences are in line with economic factors in each country.

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

- Description: A review of strategic thinking literature indicates that research has tended to focus on experiences contributing to strategic thinking, the strategic thinking perspectives that executives are likely to follow based on the environments in which they have developed their strategic competencies, and examining executives’ cognitive maps within the context of strategic management (O’ Shannassy 2003; Kutschera, and Ryan, 2009; Meyer, 2007). As an expansion of these principles and foundations of strategic thinking, this research was a study of the extent to which strategic thinking perspectives are utilised during macro environmental turbulence. According to Cravens et al. (2009: 31) volatility, reinvention, and fundamental changes in markets present unprecedented challenges to researchers and executives. “Unfortunately, too often traditional conceptual models and theories fail to provide adequate insight for coping with this new and rapidly changing business environment. Traditional market perspectives and conceptual logic may even blind researchers and strategic decision makers to the real threats present in the changing competitive landscape and new market space, and to opportunities for added value which can be uncovered and exploited” Cravens et al. (2009: 31). Hyperinflation in Zimbabwe was a major problem from 2003 to April 2009, when the country suspended its own currency and for the next five years the country continued to struggle with various macro environmental challenges. It is this backdrop that makes this research intriguing, where the soundness of any organisation is said to be crucially linked to the soundness of the macro environment, including macroeconomic policies as well as internal governance, market discipline; regulation and supervision (Louw and Venter, 2010). The research was a case study of BancABC Zimbabwe and focused on the period 2009 to 2013. BancABC Zimbabwe is a subsidiary of ABC Holdings Limited which is listed on the Botswana and Zimbabwe stock exchanges (BancABC, 2012). The aim of the study as the first key activity was to explore and describe how the BancABC executives responded to the critical macro environmental incidents identified, at a management or executive team perspective, and secondly, whether the rational reasoning or generative reasoning perspective was dominant during the period of turbulence. The goal is to gain insights of the strategic thinking process followed by executives during a period of macro-environmental turbulence. Literature defines strategic thinking concept as the cognitive process undertaken by executives in relation to problem solving in the business context. Two main perspectives are discussed: Strategic thinking as a science (rational thinking) is the prescriptive, structured nature of strategic thinking; arguments are that it is a less complex perspective for executives to adopt. Strategic thinking as an art (generative thinking) is the perspective that allows the strategist to think outside the box and be more creative about solving strategic problems. The discussion presents how the two perspectives can be used to complement each other and provide a more robust strategic thinking framework. The multi-perspective approach to strategic thinking recommends the right balance between analysis, intuition and creativity can be used to create new frameworks and innovative solutions. The ability to balance these strategic thinking perspectives enables executives to solve strategic problems (Linkov, 1999). The research findings highlighted the effect of time and availability of information on the strategic thinking perspective adopted by executives during times of uncertainty. It was noted that when time and information were available, executives appeared to use the rational strategic thinking perspective, while if there was limited time and information to solve problems the generative thinking perspective was dominantly used. Further the importance of integrative strategic thinking which facilitates the use of both intuition and analysis when solving strategic problems in a turbulent macro environment was also highlighted. The research thesis adopted the structure of a case study, relying on the critical incident technique to create the context of the study; and can be used to explore and discuss strategic thinking for teaching purposes. The results of the study can be recognised as a contribution towards the development of strategic thinking particularly in times of turbulence. It can also form the basis for future studies in the context of strategic thinking.
