- Description: The study aimed on exploring the effects of polygamous marriages on the wellbeing of African women. The study was conducted in Baziya Administrative Area in Mthatha which in Eastern Cape. The researcher seeks to examine the reasons for African women to be engaged in polygamous marriages, to investigate challenges if any faced by African women in polygamous marriage and to examine professional support services available from the department of social development, the department of justice and the department of traditional affairs in advocating for women in polygamous marriages. Feminist theory was utilized in the study which focuses on the socially constructed gender differences that are created through the process of socialization which include gender inequality. The study was qualitative in nature. Interviews were conducted with polygamous married women and group discussions were conducted with stakeholders working with polygamous married women. Data was analyzed using thematic analysis. The study recommended therapeutic treatment of emotional stress for polygamous women or treatment of related bodily ills such as gender based violence or any other type of abuse should be provided by social workers. There is a need of implementation of empowerment programs, polygamous women should be encouraged to manage their careers proactively and to make informed choices

- Description: The level of maturity in project management systems within South African universities is low. The low maturity affects project success. Organisational Project Management Maturity Model (OPM3®) – Third Edition (2013). The study is aimed at investigating and finding solutions to the perceived factors that affect Project Management Maturity at Universities’ infrastructure departments. The literature review indicates that organisations benefit from achieving organisational Project Management Maturity when projects are tied to business strategy and support business goals as opposed to when they are executed randomly (OPM3)- Third Edition (2013). A quantitative method was used to collect and analyse data. One questionnaire was put together and distributed to the targeted receipts, i.e., personnel working at infrastructure departments at South African universities, a web-based questionnaire was used to gather the data. A total of 56 responses were received to analyse the data. The stakeholders that responded were: project managers, portfolio managers, project coordinators, administrators and engineer. The study found that PMBoK and planning are factors that have an impact on Project Maturity. Recommendations were that all personnel implementing projects for University Infrastructure should be trained in earned Value Management to ensure that their PMBoK knowledge is enhanced. Other training that is recommended includes Integration Management, Scope Management, Quality Management, Risk Management, Time Management, Resource Management, Procurement Management, Cost Management and Stakeholder Management.

The elephant in the ‘room’: determinants of songbird assemblages in the Thicket Biome, South Africa

- Description: When vegetation structure is altered, songbird communities may be affected. Despite speculation that African Elephant (Loxodonta africana) browsing impacts bird communities, existing data are limited. I sampled the bird communities of the Albany Thicket Biome at 10 sites in the Eastern Cape, South Africa, half with elephants and half without. Songbird community parameters were best predicted by how long elephants had been present, elephant density and the percentage cover of thicket vegetation. The sites where elephants had been present for longer had more bird species and increased songbird density and diversity. However, bird density also increased with increasing thicket vegetation cover and this is a phenomenon unlikely to be compatible with long-term elephant presence. There was an almost equal split between the number of bird species that appeared to be negatively affected by changes in habitat structure (47%) and those which benefited (53%). Smaller birds were generally more abundant as vegetation structural integrity increased and larger birds were more abundant when vegetation structural integrity declined. The browsing of elephants could be viewed as facilitative for songbirds in the short term. However, this effect may not persist in the long term because all elephant populations (notorious tree-fellers) in the Eastern Cape are found in fenced areas where natural migration is not possible. More broadly, my data provide important insight into how avian communities respond to habitat transformation at the local and regional scales.

- Description: A consequence of the regionalisation of waste disposal services is that waste management services are no longer the primary responsibility of local municipalities but shared between local and district municipalities. The process of regionalising solid waste disposal and the regulation thereof presents unchartered territory in South Africa and raises several questions including whether, in regulating regional waste disposal services, a district municipality may do so through adopting by-laws and if so, whether these by-laws are enforceable on the local municipalities who benefit from the waste disposal service. The study confirmed the importance of cooperative governance and public participation in all decision making processes including the enactment of legislation. The absence of constitutional and legislative guidance on implementation processes for regionalisation and the overlapping nature of the functions and powers of the effected local and district municipalities are identified as challenges to the regionalisation process. The study concluded that district municipal by-laws may regulate the regional waste disposal function. These adopted by-laws, although not without boundaries, will be enforceable on local municipalities provided that the principles of cooperative governance and public participation were adhered to.

- Description: A total rewards framework plays a pivotal role in the attraction, engagement and retention of employees. The study firstly traces the history of reward and the factors that have led to the notion of a total rewards model. The study then sought to discover whether the current approach was optimal and therefore a desired strategy for the workplace of the future. Through the literary review, coupled with qualitative research with participants from well-known sizeable organisations, the research indicates that, whilst a competitive salary and benefits package is an essential factor in the employee cycle, and that pay does play a big role in the attraction of employees; once employed it is the non-financial factors that are paramount to the engagement and retention of employees. Insofar as employees believe their package is competitive and/or reflective of their contribution, they have the potential to be engaged. For that potential to be realised, it is the little things that matter to the employees that then come into force. Workplace culture, flexibility, career development, transparency, an alignment between the employee, the brand and the values of the organisation, are all vital in the engagement and retention of employees. In order for these factors to remain valued by employees, communication is essential. Manager interaction remains at the forefront of the employees’ experience at work. A positive interaction whereby coaching, development and the achievement of the little things that really matter, allow for a more productive and engaged employee, which ultimately improves the profitability and/or success of the business.

The evolution of the Lepilemuridae-Cheirogaleidae clade

- Description: The Lepilemuridae and the Cheirogaleidae, according to recent molecular reconstructions, share a more recent common ancestor than previously thought. Further phylogenetic reconstructions have indicated that body size evolution in this clade was marked by repeated dwarfing events that coincided with changes in the environment. I aimed to investigate the morphological implications of changes in body size within the Lepilemur-cheirogaleid clade, testing four predictions. Together with Dr. Couette, I collected data on the overall palate shape and predicted that shape is likely to be influenced by several factors including phylogeny, body size and diet. Geometric morphometric analyses revealed that, although a strong phylogenetic signal was detected, diet had the major effect on palate shape. In a similar vein, when examining the arterial circulation patterns in these taxa, I predicted that changes in body size would result in changes and possible reductions in arterial size, particularly the internal carotid artery (ICA) and stapedial artery (SA). Analyses with micro-computed tomography (CT) and 3D imaging indicated that changes in body size led to reduction of a functional stapedial artery in Lepilemur, making it an intermediate stage between the daubentoniid, lemurid and indriid species with large stapedial arteries, and the smaller bodied cheirogaleids with an alternative blood supply in the form of an enlarged ascending pharyngeal artery. Lepilemur is the smallest living folivorous primate, and likely to be at the threshold body size to be able to subsist on such a poor diet. To investigate shifts in dietary patterns that accompanied changes in body size, I chose to explore the reported behaviour of caecotrophy as a possible means for the sportive lemurs to derive additional nutrient from their food sources. I predicted that, if caecotrophy is a way to assist folivory at small body size, the energy contained in “caecotrophic” and latrine faecal samples should be different. Analyses showed significant iv differences between the two types of faeces and, combined with an analysis of faecal bacterial diversity, support the occurrence of caecotrophy. Finally, I compared the digestive efficiency of two small, distantly related gummivorous primates that evolved their diets convergently. I studied the digestion of gum in Microcebus griseorufus and compared this with gum digestion in Galago moholi. I predicted that an evolutionary disposition to fermentation inherited from a folivorous ancestor would aid in the digestion of gum in mouse lemurs. Results indicated that retention time was prolonged by the presence of secondary compounds in Microcebus fed with Commiphora gum but relatively shorter (< 24 hrs) when fed Alantsilodenron gum, a preferred food. Despite the fact that G. moholi has an ansa coli, which is missing in M. griseorufus species, both are highly efficient at digesting gum. These data provide some of the first indicators of how dietary changes from a larger-bodied folivorous ancestor to partially gummivorous, small-bodied descendants may have occurred in evolutionary time.

- Description: Research on sexual minority experiences has traditionally documented harrowing accounts of homophobia, harassment, and discrimination. While sexual minority’s experiences are typically imbued with physical, mental and emotional consequences, men who have sex with men and women or, MSMW may be subject to a unique homophobic experience due to their sexual identity Hence, research shows that these men may have to devise strategies to insulate themselves from discrimination and possible physical harm. This study explored how MSMW navigate their sexual identities in the presence of homophobia. The study adopted a social constructionist perspective as a theoretical lens to study these sexual navigations. A qualitative research methodology was utilised. Six male participants from KwaZulu-Natal were sampled using a combination of convenience and purposive sampling techniques. Data were transcribed verbatim and analysed using thematic analysis. The findings of this study suggest that MSMW experience forms of homophobic attitudes across different spheres of their lives. As a result, these men may draw from normative gender performances present within their communities, conceal their sexual identity by presenting themselves in heteronormative ways, and limiting disclosure of their sexuality to those closest to them, regardless of the emotional burden they may consequently carry. The findings of the study further point out that more research is needed to further understand sexual minorities’ navigation of their sexual identities in contexts that are not accepting and the social and psychological implications that this has on them.

- Description: The prevalence of childhood disability in South Africa is significant. In an attempt to meet the constitutional rights of children with disabilities, there are a variety of services available for children with disabilities. These services are aimed at rehabilitating children with disabilities and integrating them in society. Amongst such services are health services. Due to the nature of some childhood disabilities, it is recommended that they should be seen by a multidisciplinary team. While the field of childhood disability has been researched extensively. Limited research has been conducted on the experiences of health service providers working with children with disabilities and their caregivers. The current study explored the experiences of health service providers working with children with disabilities and their caregivers in the Eastern Cape. To achieve this aim, the study employed Interpretative Phenomenological Analysis (IPA). Five participants were recruited using purposive and snowball sampling methods. Semi-structured interviews were used to allow participants to freely share their experiences of working with children with disabilities and their caregivers. The interviews were audio recorded and transcribed for analysis purpose. The analysis process generated five master themes namely: Positive experiences of their work; negative experiences of their work; perception of their role as changing over time; managing challenges in their work; and experiences of a service learning programme as complementary to their work. The findings of the study highlighted both the positive experiences and the negative experiences of their work. On the one hand, the participants reported positive affect and that they found their work meaningful. They also reported a sense of feeling supported by fellow colleagues and enjoying their work at the clinics. On the other hand, the participants reported negative affect in relation to their wok difficulties such as feelings of frustration, feelings of being unappreciated by management and finding the work distressing. The participants reported that professional and emotional growth in conjunction with perspective taking contributed to developing better coping mechanisms. A service learning programme offered in the community was experienced as a good contribution to the work done at the clinics and distinguished as addressing the emotional needs of the caregivers which cannot be addressed at the clinics. The findings of the study supports and expands the literature on the experiences of health service providers working with children with disabilities in South Africa.

- Description: When patients abscond from the hospital, it is a taxing experience for everybody involved. The risk of harm to the patient is high. A small risk to the community also exits. This research aimed to explore and describe the experiences of psychiatric patients absconding from psychiatric institutions in the Eastern Cape. Data was collected making use of semi-structured interviews conducted with psychiatric patients that absconded. Data collected were analysed using Tech’s method of data analysis. The experiences and reasons for absconding identified were grouped into three main themes, namely biological factors, psychological factors and social factors. Fourteen sub-themes were identified. The fourteen sub-themes identified were correlated with Maslow’s hierarchy of needs. The participants expressed a number of unmet needs as motivation for their behaviour and the reason for absconding. A description of the profile of a psychiatric patient prone to absconding in the Eastern Cape was developed according to the demographic detail of the participants in this research. The research limitations are discussed. Recommendations were made from the findings to reduce absconding events in psychiatric institutions. Possible education and clinical practice recommendations were made, as well as recommendations provided for future related research. To ensure the quality of the study, the researcher made use of Guba’s four criteria to ensure trustworthiness. The researcher took special care to adhere to high ethical standards and protect the participants from exploitation.

Data was collected making use of semi-structured interviews conducted with psychiatric patients that absconded. Data collected were analysed using Tech’s method of data analysis. The experiences and reasons for absconding identified were grouped into three main themes, namely biological factors, psychological factors and social factors. Fourteen sub-themes were identified. The fourteen sub-themes identified were correlated with Maslow’s hierarchy of needs. The participants expressed a number of unmet needs as motivation for their behaviour and the reason for absconding. A description of the profile of a psychiatric patient prone to absconding in the Eastern Cape was developed according to the demographic detail of the participants in this research. The research limitations are discussed. Recommendations were made from the findings to reduce absconding events in psychiatric institutions. Possible education and clinical practice recommendations were made, as well as recommendations provided for future related research. To ensure the quality of the study, the researcher made use of Guba’s four criteria to ensure trustworthiness. The researcher took special care to adhere to high ethical standards and protect the participants from exploitation.

- Description: The purpose of the study was to explore and describe the experiences of student nurses regarding negotiation of condom use at Lilitha College of Nursing, East London Campus. Human Immunodeficiency Virus (HIV) infection is still one of the severe global public health problems and a considerable number of people are living with HIV and millions of these people die of Acquired Immune Deficiency Syndrome (AIDS). It has been found that women have difficulty in negotiating condom use. The study that was conducted in Tanzania revealed that when women lack selfconfidence to negotiate condom use with their sexual companions, they may be exposed to unprotected sex, thus being at danger of contracting STIs as well as HIV/AIDS and therefore being more susceptible to adverse sexual and reproductive health results (Exavery, Kanté, Jackson, Noronha, Sikustahili, Tani, Mushi, Baynes, Ramsey, Hingora and Phillips, 2012:9). A qualitative, descriptive, explorative, contextual design was used to describe the experiences of student nurses regarding negotiation of condom use and a purposive sampling method was used to select fourth year students. Eleven students participated in the study. Data was collected by means of individual face-to-face interviews with fourth year students. The interviews continued until data saturation was reached. Data analysis was done using Tesch‟s approach to open coding in qualitative research. Themes, categories and sub-categories emerged from the data analysis and were fully discussed. The results of the study indicated that students experienced difficulties in negotiation of condom use, although some participants felt that they were comfortable to negotiate. Health education and awareness campaigns were recommended as fundamental tools that could be used as strategies to enhance successful negotiation of condom use.

- Description: The study explored the psychological well-being of PLWHA in Lusikisiki, in the Eastern Cape, South Africa. The aim was to describe how they cope physically, socially and psychologically in their everyday lives as they deal with the consequences of stress while living with HIV. The researcher employed exploratory qualitative research. Fifteen participants from one of the support groups under the supervision of the Treatment Action Campaign (TAC) District office in Lusikisiki, in the Eastern Cape, consisting of seven males and eight females, aged from 20-60 gave their consent to be interviewed. The majority of the participants depended on the child support grant while others were doing part-time jobs in order to make a living. These results demonstrated that PLWHA are doing well in terms of accepting their HIVpositive status, accessing treatment and getting support. They use selfmotivation, spirituality or religion and support groups as coping strategies. However, unemployment still plays a primary role in the psychological wellbeing of PLWHA in Lusikisiki as people lack means to make ends meet which results in them constantly being in a state of turmoil, stressing about where their next meal will come from thus influencing negatively on their quality of life. It is recommended that community projects such as growing chickens and planting vegetables in gardens for generating income and for their own consumption could assist in making the lives of PLWHA better if there could be funders who would be willing to sponsor such projects.

- Description: The aim of this research was to investigate the job provisioning benefits of urban green space (GS), the ability of these jobs to alleviate poverty amongst poor urban households, as well as the potential to increase the number of Green Collar (GC) jobs. According to Lal et al. (2010), Roy et al. (2012) and others, environmental employment or GC jobs, represent the very synergy between social, economic and environmental resilience and sustainability, and have the ability to provide an additional range of goods and services. Data was collected from 12 towns and cities in the Eastern Cape of South Africa, all varying in population, town size and geographic location. Structured employer, employee and resident interviews were used to collect data, which pertained to a number of employment characteristics and employee living conditions. Throughout the sample, 19 different types of jobs were identified, and a total of 17 429 GC employees were counted, sharing a total of approximately R503 million in annual wages. Some GC employees were found to still be in a position of poverty despite employment, while others enjoyed a higher standard of living as a result, although this was largely dependent on the extent of wages and other household and employment attributes. Using lessons learnt from previous chapters, a number of data sources and a creative approach, the potential for growth and improvement in the urban GC sector was discussed, and the way forward involves private, public, informal and civil sector participation and innovation; which will not only enhance environmental and social ecosystem services, but also provide meaningful employment opportunities to the otherwise impoverished. Urban GC jobs should be widely viewed as a useful tool in achieving social, environmental and economic prosperity in urban landscapes (Bowen and Kuralbayeva, 2015).

- Description: Residues obtained during coffee processing, known as spent coffee grounds, are an abundant, low-cost and versatile feedstock for a wide range of high-value biological compounds exhibiting a number of properties which include anti-cellulite and antioxidant properties for skin-care applications. The objective of the present work was to obtain a concentrated extract containing high-value biological methylxanthines and polyphenolic compounds with antioxidant activity from the spent coffee grounds. An investigation of the effect of extraction conditions on the concentration of the bioactive compounds in the extract was done. The recovery of both methylxanthines and the polyphenolic compounds with antioxidant activity was achieved through a one-step extraction method under reduced pressure using a non-toxic solvent blend. Various experimental designs were implemented with the aim of optimising the recovery of the selected bioactive compounds, namely, caffeine, theophylline and theobromine from spent coffee grounds by using solvent blends of water and ethanol. A number of factors considered were: (i) repeatability, (ii) extraction time, (iii) composition of solvent blends, (iv) extraction vacuum (pressure)/temperature settings and (v) operating variables. The results suggested that an optimal recovery of the bioactive compounds will be obtained at a two-hour extraction time with a solvent blend of 100% water to maximise caffeine, theophylline, total phenolic content and percentage antioxidant activity, while extraction of theobromine is optimal using aqueous ethanolic solvent mixtures. The optimal vacuum (pressure) setting was found to be 250 mbar to maximise percentage antioxidant activity. The methylxanthines and total phenolic content were not affected by the vacuum (pressure) and temperature settings. Freezedrying the spent coffee grounds before extraction ensured long-term stability of a reproducible sample and achieved better recovery of the important bioactive compounds. Extraction was performed under reduced pressure in order to reduce solvent reflux temperature and to improve extraction efficiency. The quantitative and qualitative determinations of the above-mentioned high-value compounds were performed by high-performance liquid chromatography (HPLC), which confirmed the presence of the methylxanthines in the extracts. In the extraction of methylxanthines, it was found that caffeine was more abundant in the extract as compared to theophylline and theobromine. The extracts were incorporated into three cosmetic gel formulations. Release studies of caffeine, theobromine and theophylline were performed using the three formulated cosmetic gels with the use of a Franz diffusion cell. It was found that theobromine and theophylline were not detected from the gel samples as they were present in too small amounts in the original extracts and there was no significant difference in the release rates of caffeine when comparing the three different gels. Caffeine was released within 15 minutes. All three gels displayed a pseudoplastic viscosity profile and the different viscosity values of the three gels did not influence the release of caffeine significantly.

- Description: Through an effective system of knowledge management, organisations can evaluate which factors play in important role in ensuring that knowledge is managed well within the organisation. It is believed there are several factors influencing knowledge management effectiveness, including knowledge sharing, commitment and trust, culture, motivation and incentives, mentoring, group work, training, storytelling and networking, etcetera and also, there are various models, and analytical tools that can be used to study the relationships between some key influential factors and the effectiveness of knowledge management. Based on previous research, this study aims to identify and evaluate the key factors that influence the effectiveness of knowledge management in an organisation. Purpose: Knowledge in an organisation tends to be a resource that gets less attention and only after it has been lost or neglected, does management take a look. At this stage it is normally too late to do anything that can assist the organisation. Drawing on dilemma and previous studies done, the aim of this study is to understand and evaluate the factors that influence the effectiveness of knowledge management in an organisation. Methodology: Based on a literature review, a mixed research model is initiated integrating demographics, employee morale, organisational performance, information sharing, knowledge management strategy and a communication gap as some of the factors that have an influence on effectiveness of knowledge management. The mixed model is tested in the study using questionnaires, interviews, observations and focus group discussions. The study was done using a statistical sample of 25 participants who participated in all the forms of the study, meaning they all did the questionnaires, interviews, observation and focus groups. The analysis of the feedback resulted in both qualitative and quantitative data, hence the study had to settle for a mixed method approach. Findings: The findings point towards the general drivers and barriers to knowledge management within the organisation. The significant drivers are: mentoring, networking, training, group work storytelling. The significant identified influencers to xi knowledge management are: employee morale, information sharing, communication gap and employee tenure. Originality: The study contributes to an understanding of factors that influence the effectiveness of knowledge management in an organisation. Keywords: Information sharing, Knowledge management, Communication gap, Employee morale, Organisational performance, Mentoring, Storytelling, Networking, Training.

- Description: This study investigated the scalability of tenderpreneurs in South Africa. The South African government has invested a lot of capital towards small and medium-sized enterprises (SMEs), through the tender system. The unemployment trend in the country continues and is a reflection of symptoms and problems that impede the effectiveness of government initiatives such as the tender system. The main aim of this study was to establish the factors influencing the scalability of tenderpreneurs in South Africa. Further objectives intended to establish the factors that would enable tenderpreneurs to scale their businesses, to define the characteristics of a tenderpreneur in South Africa, to determine the factors that influence the growth of tenderpreneurs in South Africa and to establish the strengths, weaknesses, opportunities for and threats to the scalability of tenderpreneurs in South Africa. In order to achieve the said objectives, a sample of ten tenderpreneurs from the Ilembe District in KwaZulu-Natal, was selected from an estimated population of over 50 tenderpreneurs in the region, using the convenience sampling technique. The phenomenological paradigm was employed and qualitative research was done using the exploratory research design. Semi-structured interviews were used to collect data for the study. The findings of this study characterised a tenderpreneur as an individual bent on providing requested services, engaging in competitive bidding, usually awaiting opportunities or bids, who do business with or without prior capital. In the political front, the advent of the end of the apartheid era, the emergence of the democratic movement and emancipation of the black majority contributed to the drive towards business ownership by the previously disadvantaged groups. Recommendations made included the fact that the relevant government authorities should assist in supporting the tenderpreneurs through a number of policy and political initiatives such as ensuring broader stakeholder participation, fostering established public funded partnerships, mainstreaming corporate social investment to uplift communities, enforce sustainable business practices and drive infrastructure development.

- Description: Bank failure continues to feature in South Africa and although it is not uncommon, nor limited to any single country, it has the potential to have significant systemic risks. It is, therefore of the utmost importance to mitigate bank failure where possible. Bank supervision plays a key role in ensuring that individual banks, and the banking sector, remain sound. This study analysed seven selected banks in South Africa namely, ABSA, African Bank, Capitec Bank, FirstRand Bank, Nedbank, Standard Bank and VBS Mutual Bank. The CAMELS rating system was applied to evaluate the component and composite ratings for each selected bank. The empirical evidence exhibited that the CAMELS model has been used world-wide and proved valuable in its simplicity and reliability. The results showed that all banks achieved a rating of three or fair, with the exception being African Bank. African Bank, rated four or marginal, continues to struggle to regain market confidence since its cu0ratorship and restructuring. The study further showed that among the selected banks, management quality and liquidity were two components that consistently showed critical weaknesses, which posed concerns for formal supervision. The study utilised One-way ANOVA (Analysis of Variance) to analyse the results of the CAMELS model. It was found that there was no significant difference in the financial soundness of the selected banks as a measure of the CAMELS model. The study further recommended that the banks invest and focus on developing human resource departments to attain and retain high quality managers in terms of qualifications and experience. The banks’ internal policies need to align, not only with the company’s business targets, but also the personal contentment and fulfilment of employees and managers. This will help reduce frictional unemployment in the banking sector. It must be noted that Capitec was the only bank to avoid a marginal or weak rating in the management quality component. To address the poor rating awarded to the liquidity component in all selected banks, it is recommended that senior management, regulators and supervisors need to work together to implement sound liquidity management practices. The CAMELS model presents a clear depiction of the financial soundness of a bank and can be comparable to other competitive banks within a country. For this reason, the model would be easily understandable, not only to supervisors and senior management, but also investors, stake-holders, their customers and the general population. It is therefore recommended that the SARB publishes a detailed annual report, which analyses all banks in South Africa by way of the CAMELS model.

- Description: Bank failure continues to feature in South Africa and although it is not uncommon, nor limited to any single country, it has the potential to have significant systemic risks. It is, therefore of the utmost importance to mitigate bank failure where possible. Bank supervision plays a key role in ensuring that individual banks, and the banking sector, remain sound. This study analysed seven selected banks in South Africa namely, ABSA, African Bank, Capitec Bank, FirstRand Bank, Nedbank, Standard Bank and VBS Mutual Bank. The CAMELS rating system was applied to evaluate the component and composite ratings for each selected bank. The empirical evidence exhibited that the CAMELS model has been used world-wide and proved valuable in its simplicity and reliability. The results showed that all banks achieved a rating of three or fair, with the exception being African Bank. African Bank, rated four or marginal, continues to struggle to regain market confidence since its cu0ratorship and restructuring. The study further showed that among the selected banks, management quality and liquidity were two components that consistently showed critical weaknesses, which posed concerns for formal supervision. The study utilised One-way ANOVA (Analysis of Variance) to analyse the results of the CAMELS model. It was found that there was no significant difference in the financial soundness of the selected banks as a measure of the CAMELS model. The study further recommended that the banks invest and focus on developing human resource departments to attain and retain high quality managers in terms of qualifications and experience.

- Description: Facultative hyperthermia, the elevation of body temperature above normothermic levels, during heat exposure, importantly affects the wa-ter economy and heat balance of terrestrial endotherms. We currently lack a mechanistic understanding of the benefits hyperthermia provides for avian taxa. Facultative hyperthermia has been proposed to minimize rates of water loss via three distinct mechanisms: M1) by maintaining body temperature (Tb) above environmental temperatures (Te), heat can be lost non‐evaporatively, saving water; M2) by minimizing the thermal gradient when Te > Tb, environmental heat gain and evaporative water loss rates are reduced; and M3) by storing heat via increases in Tb which reduces evaporative heat loss demands and conserves wa-ter. Although individuals may benefit from all three mechanisms during heat exposure, the relative importance of each mechanism has not been quantified among species that differ in their body size, heat toler-ance and mechanisms of evaporative heat dissipation. We measured resting metabolism, evaporative water loss and real‐time Tb from 33 species of birds representing nine orders ranging in mass from 8 to 300 g and estimated the water savings associated with each proposed mechanism. We show that facultative hyperthermia varies in its benefits among species.

- Description: The research effort developed four possible scenarios for the future of banking in South Africa towards 2055. The scenarios sought to stimulate thought on the possible, probable, plausible and preferred effects of disruptive innovation and regulation in the South African banking sector. The scenarios were developed in strict accordance with the 5 stages, and 9 steps, of the scenario-based planning process of futures studies. A conceptual futures studies model for banking in South Africa was developed to guide and clarify the way in which the research on South African banking can be integrated into the body of existing futures studies theory. The research study began with a comprehensive environmental scan, where various megatrends and driving forces are identified. A PESTEL analysis provided a deeper understanding of the driving forces. A Real-Time Delphi study was conducted in order to validate and prioritise the megatrends and driving forces that emerged. As a result, the research study was able to present four plausible scenarios that provide a better understanding of the future of banking in South Africa over the decades to come. The research presents banking as a complex, multi-faceted sector that is heavily influenced by advances in technology. The Real-Time Delphi research allowed the aggregation of expert knowledge. This is used as a guide to assist decision-makers and industry leaders in the adoption of appropriate business models and strategies towards a preferred future state. The research defined the Integrated Vision as the preferred future state for the South African banking sector towards 2055. The study closes a research gap where current strategies deviate from proposed strategies that drive the achievement of the Integrated Vision by 2055. Finally, contextually aligned practical recommendations are provided to assist decision-makers, industry leaders and change agents to work towards a preferable future state. The proposed recommendations are placed into broad categories of innovation, financial inclusion and collaborative regulatory relationships. The research makes a meaningful contribution to the South African banking sector by introducing a forward-looking, systems-thinking approach to disruptive innovation and regulation in the South African context.

- Description: 3D printing is one of the most disruptive technologies that truly has the potential to change medicine and healthcare by making care affordable, accessible and personalized. It can bring a new era if printers become more sophisticated, printing biomaterials gets safely regulated and the public acquires a common sense about how 3D printing works. An understanding and appreciation of the possible futures of 3D printing technology will be of great value to various stakeholders within the country. This research will identify and describe current drivers that should be appreciated for the government, business communities, academic institutions, healthcare provider’s policy makers and the society at large to make intelligent decisions about the future of 3D printing in medical devices. This study is aimed at identifying the possible futures of 3D printing in orthopaedic devices in South Africa. Causal Layered Analysis (CLA) and the Six Pillars of Futures were identified as the preferred methodologies to be utilised to respond to the research objectives of this study. A detailed literature study was undertaken to evaluate the existing body of knowledge on the research topic. The literature study revealed that several factors needs to be addressed before 3D printing is completely integrated into everyday joint reconstruction surgery. Having already made a big impact in the medical sector, three-dimensional printing (3DP) technology continues to push the boundaries of cost efficiency, convenience, and customization. It has transformed some aspects of medical device production. To date, 3D printing has been employed predominantly by hobbyists, product designers and a few select industrial applications, but the performance of additive manufacturing equipment is quickly evolving, the choice of materials is increasing, and prices of both materials and printers are falling rapidly, all factors through which 3D printing is swiftly progressing to attain wider consumer acceptance and a greater number of manufacturing uses.
