- Description: With the completion of the human genome project at the beginning of the 21st century, the biological sciences entered an unprecedented age of data generation, and made its first steps towards an era of personalized medicine. This abundance of sequence data has led to the proliferation of numerous sequence-based techniques for associating variation with disease, such as Genome-Wide Association Studies (GWAS) and Candidate Gene Association Studies (CGAS). However, these statistical methods do not provide an understanding of the functional effects of variation. Structure-based drug discovery and design is increasingly incorporating structural bioinformatics techniques to model and analyze protein targets, perform large scale virtual screening to identify hit to lead compounds, and simulate molecular interactions. These techniques are fast, cost-effective, and complement existing experimental techniques such as High Throughput Sequencing (HTS).

- Description: The African Union’s role in the formulation and the implementation of the Arusha Agreement in Burundi has been hailed as a hall mark of success for the organisation’s conflict management on the continent. A decade and a half later Burundi once again finds itself at the precipice of civil war due to the controversy surrounding President Pierre Nkurunziza’s election to a third term in office in 2015. At the time of writing, the mediation efforts are tethering on the brink of failure. The African Union’s response to the political crisis in Burundi has been characterised by policy incoherence, reversals and ineffectiveness as member states have not committed to a particular strategy. This study explores the underlying factors that resulted in the failure of the African Union’s mediation efforts in Burundi by analysing the contingency framework for mediation by Bercovitch Anagnoson and Wille (1991: 11) with specific reference to the eight context variables. The study seeks to understand the failure of mediation in the context of the African Union’s previous success in mediating the signing of the Arusha Agreement. The study reveals that the competing and contradictory narratives surrounding the mediation and the conflict played a significant role in influencing the outcome of the mediation. The study concludes that mediation remains a relevant conflict management strategy for the African Union. The normative framework of the regional organisation however must be shifted to reconceptualise the principle of sovereignty in responding to electoral based conflicts.

- Description: All employers at some point in time may find themselves under pressure, facing financial challenges, which may force them into contemplating some reductions in their operating costs. This could result in an exercise that may entail restructuring the wage bill. This in turn could eventually result in the dismissal of employees for operational reasons. The concept of job security is a new phenomenon in the labour market and with localisation and the economic crisis that have caused businesses to become competitive, workers face the threat of losing jobs daily. It must be stated that the International Labour Organisation (hereinafter referred to as ILO), which is an international body responsible for developing principles and guidelines which regulate labour relations in the world, had only in 1963 taken some steps to give due regard to the law that seek to promote employment security1. Until then, the common law dictated the nature of the relationship with regard to the rules that govern the termination of employment. The study will further investigate the international trends in the embedding of the Convention of Termination of Employment. Against this context, this treatise seeks to highlight the work done to further provide measures of employment security for workers facing dismissal based on operational requirements. The study will examine the role of the Commission for the Conciliation, Mediation and Arbitration (hereinafter referred to as CCMA), an impartial body in South Africa, whose main function is to prevent and resolve labour disputes, as well as to mitigate job losses in the context of operational requirements dismissals.

- 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: Countries should encourage their workforce to foster human development as it contributes to the economic development through having a well-trained and skilled workforce. The countries that are economically developed have stood out because of human capabilities that have triggered economic development. With innovation being one of the major advantages of human capital, new ideas lead to the creation of vast employment opportunities especially for those that have studied critical skill subjects. The economic status of Zimbabwe shows that there is human capital development happening in the country, but there is a serious shortage of skills in sciences, technology, engineering and mathematics that are necessary for the industrialisation of the country. The government believes that Zimbabwe can industrialise if STEM education is integrated in the country’s educational system to make human capital development wholistic. The study aims to understand the concept of human capital development and how it can be developed at a balance. A discussion on the primary role of universities and higher learning institutions on developing human capital will be done. Universities educate and equip students with knowledge and skills, hence both STEM and non-STEM curricula is needed to develop human capital that is balanced. This is because STEM graduates that are innovative can create jobs for non-STEM graduates and help a country to industrialise and develop its economy. Universities are recommended to increase public awareness of STEM, train teachers specifically for STEM, invest in research and development and develop STEM-related policies and systems to develop more STEM graduates to strike a balance with non-STEM graduates and enhance industrialisation in Zimbabwe. Interviews were conducted and analysed and some of the recommendations made were to encourage the government to deregulate to attract investment, to increase the public’s awareness of STEM and to train STEM teachers accordingly.

- Description: Community participation in municipal affairs is the bedrock of participatory democracy, and it has been hailed as the panacea for most public community programmes in South Africa. High-level public community participation empowers communities, increases self-reliance, self-awareness and confidence in self-examination of problems and seeking solutions for them. Community behavioural changes are promoted and utilisation and support of services is facilitated, which are of great significance to all community efforts, especially in areas where the service delivery rate from municipalities is low. The vehicle for driving community participation is the system of ward committees, legislation that is rooted in the Constitution, the Municipal Structures Act, and the Municipal Systems Act. The study sees community participation as people being involved in government decision-making that affects them directly or indirectly. It involves three types of action, namely facilitating rational deliberation, creating and communicating moral principles, and expressing personal and group affects and needs. This research investigated the role of ward committees in enhancing community participation from a South African perspective. Municipalities are organisations tasked with ensuring the equal distribution of services to local communities. Municipalities were chosen on the basis of commitment to communicate effectively with the community and in turn to encourage the community to participate fully in municipal activities. The study is conducted within the parameters of the Constitution of South Africa (1996), which mandates local government to provide a democratic and accountable local government, and to encourage the involvement of communities in the matters of local government. Section 152(1)(e) of the Constitution stipulates that the objective of local government, amongst others, is to ensure the involvement of communities and community organisations in matters of local government, and section 73 of the Local Government: Municipal Structures Act (Act No. 117 of 1998), further requires municipalities to establish ward committees in a manner that seeks to enhance participatory democracy at the local sphere of government. The study therefore investigated the role of ward committees in enhancing community participation. Ward committees are advisory bodies created at ward level in terms of the Municipal Structures Act (Act No. 117 of 1998), and consist of the ward councillor (who is the chair) and not more than 10 members representing diverse groups within a particular ward. The White Paper on Local Government (1998) further indicates that municipal councils should promote the involvement of citizens and community groups in the design and delivery of municipal programmes. A literature survey was conducted to investigate and conceptualise the role of ward committees in enhancing community participation, and to determine the responsibilities of ward committees in municipalities. A desktop approach was used to track down useful existing pre-published information (also known as secondary research), with the data collection coming from secondary sources, such as municipal records. A number of recommendations regarding the improvement of ward committees were made. Recommendations are provided for enhancing community participation in different municipalities in South Africa. It is envisaged that these changes could impact positively in encouraging community participation and ultimately improve service delivery.

- Description: Various South African studies have shown that rural households use NTFPs as safety nets in times of misfortune. However being focused on one or two sites, they do not show the prevalence of NTFP use as safety nets across multiple sites. In addition, they do not show the use of NTFPs as safety nets by rural households in different agro-ecological zones. The results of the study showed that about 79% of the total households interviewed experienced at least one shock of some magnitude in the previous 12 months. The most experienced shocks were illness, death, crop failure, and hunger. The households employed various coping strategies in response to different types of shocks, with the three widely used strategies being assistance from friends and relatives, using cash savings, and using NTFPs. Households in low agro-ecological zones used NTFPs as safety nets more than households in high agro-ecological zones.

The safety of navigation and the role of port state jurisdiction: a South African perspective

- Description: This thesis set to examine whether South Africa has incorporated the provisions on vessel navigational safety standards established in the relevant international instruments developed by the IMO: the International Convention for the Safety of Life at Sea, 1974 (SOLAS) as amended, the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers, 1978 (STCW) as amended, and the Convention on International Regulations for Preventing Collisions at Sea, 1972 (COLREGs) as amended. It also set to determine the regulatory scope for the exercise of port State jurisdiction from a South African perspective. To establish whether a vessel’s condition complies to prescribed navigational safety standards, the relevant international instruments require States that have ratified the instruments not only to ensure that vessels registered under their flag are inspected for compliance before they can navigate, but that foreign visiting vessels must be surveyed to ensure that they also comply with the safety standards. These surveys are conducted while vessels are in the port of a port State. In addition, the Third United Nations Convention on the Law of the Sea, 1982 (LOSC), provides in article 218 that the port State may enforce anti-pollution regulations committed by a vessel that calls at one of its ports, after committing an illegal discharge outside the territorial waters of the State and its exclusive economic zone (EEZ). However, the provisions of article 218 LOSC have been the center of scholarly debate on the scope of port State jurisdiction (PSJ). Whilst one school of thought holds that PSJ refers only to the provisions of article 218 LOSC, another contends that in defining PSJ, its meaning must be awarded a broader scope to include the regulation of navigational safety standards. Due to the varied opinions on the scope of PSJ, this thesis examined the regulatory framework for the exercise of port State jurisdiction (PSJ) in South Africa. The discussion was relevant to determine the role of PSJ to enhance navigational safety from a South African perspective. This thesis comprised of an in-depth analysis of primary and secondary sources of data relevant to the regulation of navigational safety. The data obtained was critically discussed to establish whether the relevant international navigational safety standards are incorporated into South African law. The process included critical discussions on the principle of jurisdiction, and its exercise by States under international law. The discussions analysed the complexities associated with defining jurisdiction and determining its scope, which are relevant in respect of States’ competence to prescribe and enforce domestic laws, in conformity with the requirements of the LOSC. International law awards jurisdiction to the State to regulate laws within its national territory subject to some restrictions. However, the meaning of jurisdiction is not easily discernible even to lawyers. The discussions showed that the Republic exercises jurisdiction in conformity with generally accepted grounds for the exercise of jurisdiction, and that it is the prerogative of the State to adopt laws it deems necessary within its territory. Thus, the incorporation of international instruments on the safety of navigation is not a forgone conclusion, as it is dependent on the will of the State to ratify, and give effect to the provisions of the relevant instruments in its domestic law. Furthermore, this thesis discussed the relevant international safety instruments in contrast to the provisions of South African merchant shipping regulations, to identify any regulatory gaps in the incorporation of their provisions in South African law. Against a background of comparative analyses of the international norms and the provisions of South African merchant shipping regulations, this research found that a significant number of the relevant international safety instruments are incorporated into south African law by Merchant Shipping Act (MSA) as amended, and regulations made in terms of the Act. The provisions of South African merchant shipping regulations are administered by the South African Maritime Safety Authority (SAMSA). However, whilst this research found little doubt that the provisions of the STCW and COLREGs are given full effect in South African law, it identified regulatory differences in respect of the most relevant of all international instruments with regard to the safety of navigation, SOLAS. Some SOLAS provisions in respect of navigational safety are not incorporated into domestic law, and in some instances where they are incorporated, the provisions of domestic law contrasts that of SOLAS, or are not as comprehensive. For instance, there is a contrast in the provisions of the Navigation Bridge Visibility Regulations (NVBR), that make the regulations applicable to vessels of 45m or more in length constructed before 1 July 2008. Whereas, SOLAS regulations in respect of the navigation bridge visibility standards of vessels apply to vessels 55m or more length. Furthermore, a 5 months extension may be awarded in respect of a safety certificate issued for a South African vessel that is not in the Republic on the date of its expiry. This provision goes beyond the requirement of SOLAS, which requires that no extension be granted for a period longer than 3 months. Likewise, SAMSA may grant an extension of a safety certificate other than a cargo vessel construction certificate, for a period no longer than five month to enable a foreign vessel to complete its journey to its country of registry or point of inspection. This extension again, is longer than the 3 months requirement under SOLAS. Moreover, the survey requirements applicable to all South African vessels where ever they may be, and all foreign merchant vessels that come into the Republic, do not reflect the specific provisions of SOLAS. A significant amendment was made to SOLAS by SOLAS PROT 1988. SOLAS PROT 1988 introduced the harmonised system of survey and certification (HSSC) into the provisions of SOLAS, thereby harmonising its survey standards with those of other international instruments. SOLAS PROT 1988 has come into force for all States that have ratified the Protocol since the year 2000. This thesis finds that while South Africa is a party to SOLAS as amended by SOLAS PROT 1978, the Republic has not yet ratified SOLAS PROT 1988. Hence, the Republic is not bound to any requirements of SOLAS PROT 1988. Furthermore, although States that are not party to an international instrument requiring the implementation of the HSSC are invited to implement the HSSC anyway, there is no provision in the MSA that incorporates the HSSC. Of central importance to the regulation of merchant shipping standards, States are not only required to adopt domestic laws giving effect to international standards, but they are required to implement international standards in a uniform manner. This is aimed at avoiding a merchant shipping arena plagued by conflicting unilateral domestic rules. SOLAS PROT 1988 has been ratified by States comprising of 96% of the world’s merchant fleet by tonnage. The massive acceptance of SOLAS PROT 1988 is indicative of the international trend, towards uniformity in the implementation of international norms. This thesis recommends that, for the Republic’s merchant shipping regulations to reflect the international trend, the Republic should amend its merchant shipping regulation to incorporate the HSSC. Alternatively, the Republic may ratify SOLAS PROT 1988, and give full effect to its survey and certification standards and the relevant navigational safety provisions in the ANNEX of SOLAS.In addition, whilst a debate abounds on the international scene in respect of the scope of port State jurisdiction, the analysis of the regulatory framework for the exercise of port State jurisdiction in South Africa found that the regulatory framework for the exercise of port State jurisdiction by the Republic includes the regulation of not only environment-related navigational standards prescribed by article 218 LOSC, but also, navigational safety standards, and significantly, its scope is not burdened by the international law limitations to the exercise of coastal State jurisdiction. As such, a recommendation is made to the effect that when defining PSJ, its scope should not be limited to the enforcement of standards contained in article 218 LOSC, rather, it should be awarded a broader scope to include the regulation of other navigational standards including safety.

- Description: Historically, placers of economic importance at Sibanye Gold's Beatrix No. 3 Shaft were Beatrix Reef, Aandenk Reef and Composite of the two reefs. Recently, the VS5 placer has emerged to be a significant contributor of ore tonnages mined on the Shaft as mining advances into deeper levels towards the northern portion of the mine lease area. Gold concentration in the VS5 Reef is highly variable from uneconomic, through marginal to economic gold values. A good knowledge of the sedimentological framework of the VS5 Reef was considered necessary in order to interpret the variable distribution of the gold within the VS5 placer. The aim of this study was to determine the depositional environments that played a major role during the formation of the VS5 placer by means of investigating the macroscopic sedimentological parameters of this particular reef. These sedimentological parameters were used as the basis for the subdivision of VS5 Reef into different facies recognized in the mine and surrounding areas. It was recognized that the VS5 placer was formed in a distal, braided fluvial environment by the reworking of the pre-existing Aandenk Reef by new materials containing significant amount of nondurable materials (see definition on page xii) such as shale detritus. Where there is no evidence of reworking of the older Aandenk Reef, the VS5 Reef occurs as poorly sorted, polymictic conglomerate with abundance of non-durable detritus. This is referred to as the Immature (IV) VS5 facies and occurs in the northern portion of the study area. The degree of reworking of the gravel bars by waves and current action resulted in the formation of well sorted, oligomictic conglomerates of the Beatrix facies in the southern portion of the mine. At the boundaries between the Immature VS5 and Beatrix facies occurs the Transitional (Sub-mature) VS5 facies, characterized by reef comprising a polymictic upper portion and a basal more mature oligomictic unit. The Transitional VS5 facies extends across the current central northern mining faces of Beatrix No. 3 Shaft with a northwest-southeast trend. There is a strong correlation between the VS5 lithofacies and distribution of gold mineralization. The Immature VS5 facies is poorly mineralized, with gold values averaging 200 c.m.g/t and lower. The Transitional (Sub-mature) VS5 facies has elevated gold values, ranging from 300 c.m.g/t to 1500 cm.g/t. Mineralization in this unit tend to be bottom loaded as well as at the base of each cyclic unit. The Beatrix facies records the highest grades averaging >1500 cmg/t. The improved understanding of the VS5 lithofacies made it possible to predict gold mineralization and aid planning to mine into viable VS5 areas.

The study concludes and notes that: The current social security system provides an inadequate prevention strategy for employees involved in MVAs. A blanket program of fitness for work as an occupational accident prevention tool should be legislated and be part of the OHSA general duties of employers to their employees. A social security system that attempts to address loss of ability to earn as a result of occupational injury must incorporate an integrated approach towards prevention of risks, compensation and rehabilitation. Social security legal instruments currently providing compensation for employees involved in MVAs (RAF and COIDA) are promulgated for more benefits. A RTW plan, Vocational assessment and rehabilitation of injured employees, all processes that will aid continued employment for injured employees, will be included. This will ensure that employees continue to earn income which forms the basis of social security.

- Description: The principal aim of this study was to assess the socio-economic contribution of nontimber forest product (NTFP) trade to households in Zomba and Machinga, southern Malawi. Quantitative and qualitative data were collected through several methods, including a household survey using questionnaire interviews, focus group discussions, key informant interviews with individual traders, direct observations, and literature review. The quantitative data were analysed statistically using SPPS version 16.0 while the qualitative data were analysed thematically. NTFP trade was the third important source of cash income for 15% of the households, although the level of use, buying and selling of NTFPs varied across the four study villages. All households in all the study villages used firewood (100%), and most used thatch grass (94%), bamboo (96%), wood for building (92%), largely as construction materials. However, the percentage of households buying NTFPs was lower, with the maximum percentage of households being 50%. The percent of households engaged in selling at least one NTFP was lower still at 39%. Substantial cash incomes were generated from firewood and edible orchids sales which provided up to a maximum of Mk180,000, equivalent to US$456, per year. Households joined the trade mostly for an alternative source of cash income due to poverty and to meet basic needs when other options were not available or feasible. Cash income generated from NTFP trade acted as a safety net and a coping strategy when other avenues supporting livelihoods were not accessible. The socio-economic benefits derived from NTFP trade were associated with the quantities collected, sold, market forces influenced by the law of demand and supply. The small amounts of cash income generated by most households were important as they supplemented household cash needs. There was a strong association between NTFP trade as one of the important sources of cash income and the number of months a household had food from their own garden in a year. There was a significant relationship though weak between ranking of NTFP trade and livestock ownership by households. Value chain analysis was used as an analytical tool to understand the processes involved in NTFP trade. The value chains for the products under study were short, dominated by traders and some intermediaries. Most of the products were sold in local markets with little value addition. This study recommends that policy makers should integrate NTFPs into their development plans, emphasizing the establishment of management strategies that will enhance availability and sustainability of the resource. NTFPs contributed to the livelihoods of the households socially and economically through provision of food, cash income, energy for cooking, medicine and construction materials.

- Description: Urban areas have become strategic locations where many throng to for a better life. However, wealth and economic opportunities are not evenly distributed in these urban spaces. South Africa is a fairly young democracy whose urban landscape has been largely shaped by the colonial apartheid system. The apartheid system segregated and relegated the black majority to the fringes of the cities into crowded communities characterised by poor living conditions, exclusion from the mainstream economy and limited urban amenities. Townships epitomise the harsh reality of the urban poor and how underdevelopment has been perpetuated. South Africa came up with different policies to redress the historical imbalances and inform urban development strategies. Urban renewal has been implemented as a development strategy in various cities across the world in an attempt to revive and improve the social, economic and environmental state of derelict urban spaces. Townships in South Africa have been the target areas for urban renewal with 8 presidential nodes having been initially identified for such in 2001. Eventually, Helenvale was added to the mix as a prime node in 2006 and the Helenvale Urban Renewal Project (HURP) was birthed - Helenvale and HURP being the identified site and project for this research respectively. An evaluative approach was adopted in assessing the socio-economic impact of urban renewal in South Africa townships and more specifically the socio-economic impact of HURP. Helenvale, like most townships in South Africa, is characterised by a high density settlement pattern, poverty, high unemployment, high rate of violence and crime, drug trade and substance abuse as well as a high rate of school dropouts. The Helenvale Urban Renewal Project (HURP) was implemented by the Nelson Mandela Bay Municipality (NMBM) and eventually the Mandela Bay Development Agency (MBDA) with the intention to rejuvenate the community on the social, economic and environmental front. The study findings showed that Helenvale, like all urban renewal nodes in South Africa had a number of socio-economic issues which prompted HURP. These include high unemployment (was 53.5% in 2013); alarming levels of violence and crime; drug trade and substance abuse and high rate of school dropout. Between 2007 and 2014, different projects were implemented under HURP, focusing mainly on physical development and community building. Study respondents had mixed reactions and perceptions of the impact of HURP. On one hand, the project saw the community benefit from the constructed public facilities like recreational parks and resource centre as well as capacity development and created employment opportunities. On the other hand, unemployment has persisted with only a small proportion of the population benefiting from the created jobs; crime remains unabated; drug trade has persisted leaving parents fearing for their young and gang violence has rendered the provided safe public physical features ineffective and the housing challenge has also not been resolved. By and large urban renewal and in this particular study, HURP has made great strides in improving the social and economic standing of the township community despite the challenges that are still lurking. A number of recommendations were proposed for similar studies and for urban renewal initiatives in South Africa. For the latter the study recommended having a robust policy that speaks to urban renewal directly and informs such. Other propositions include allowing the community to own and be stewards of urban renewal initiatives; allocating enough resources, both human and financial; and tailoring the project to respond to the needs of a particular community and not a one size fits all approach. In terms of similar studies the study recommends using a mixed methods approach to evaluate the impact of such ventures as well as evaluating more than one urban renewal initiatives for comparison and to allow for the generalizability of the findings.

- Description: In the context of rapid globalisation, skilled South African employees and professionals are often attracted overseas to take up new work opportunities in foreign countries. This may cause these individuals no longer to be “ordinarily resident” in South Africa. At the same time, changes in modes of travel, information and communication channels could result in companies and trusts no longer being considered to be tax resident in South Africa, if the place of effective management for these entities is moved to a foreign country and a double taxation agreement between South Africa and that foreign country deems these entities to be exclusively resident in the foreign country. The objective of this thesis was to analyse the tax implications that could arise when a resident natural person, trust or company ceases to be a resident or when a Controlled Foreign Company (CFC) ceases to be a CFC. A detailed analysis of the “exit charge” in section 9H of the Income Tax Act was undertaken to understand its normal tax implications when a natural person, trust or company ceases to be a resident or a CFC ceases to be a CFC. This included an analysis of how a natural person, trust or company ceases to be resident or how a CFC ceases to be a CFC. It was found that certain normal tax principles consistently apply to when a natural person, trust or company ceases to be resident or a CFC ceases to be a CFC. At the same time, certain unique normal tax implications arise for trusts and CFCs since they are impacted by the special tax rules that apply to these entities. Furthermore in the case of a trust, a judicial precedent has established that the “exit charge” remains and is taxable in the trust. For CFCs, there is uncertainty as to whether the “exit charge” could arise when a shareholder ceases to be resident, which results in residents no longer holding more than 50% of the total participation or voting rights in that foreign company.

- Description: Sorghum is the fifth most important cereal in the world and a staple food for humans. It is also a source of food and fodder for animals. In addition to the abiotic stresses such as drought, parasitic weeds of the genus Striga cause losses in sorghum production in sub Saharan Africa. Striga asiatica is a parasitic weed that attacks cereals in low input agricultural systems and is distributed throughout semi- arid regions of Africa. Most sorghum producing farmers rely on tolerance for their harvests in Striga infested fields yet the stability of tolerance in the face of a changing climate (recurrent droughts), new farming systems (mulch based agriculture) and existence of various Striga strains needs further investigation. Reduced strigolactones production was also studied as a resistance mechanism. The first study was focused on the determination of tolerance of Striga asiatica infested sorghum under drought in a pot study. Five sorghum lines were subjected to infestation with Striga and some were not infested while watering was done at 50 percent field capacity (FC) and 100 percent FC. The results showed that the five sorghum lines differed significantly in chlorophyll content and Normalised Differential Vegetation Index (NDVI). Infection did not lower chlorophyll content when it co-occurred with drought across all sorghum lines. Drought and infestation had mutually exclusive effects on chlorophyll content and NDVI. Under infestation, internode length was similar both at 100 percent FC and at 50 percent FC while under uninfested conditions, 100 percent FC gave the longer internode compared to 50 percent FC. Both infestation and irrigation regime reduced the sorghum head weight, illustrating that the two effects have synergistic effects on sorghum head weight. The second study sought to determine the effects of mulching and infestation on sorghum spp tolerance to Striga asiatica. The experiments were carried out in the seasons 2013/14 and 2014/15 summer seasons. The results indicated that mulching increased chlorophyll content in the 2014/15 season which was a drier season compared to 2013/14. In the 2014/15 season, mulching increased chlorophyll content in all varieties except Ruzangwaya, Mukadziusaende and SC Sila. When the same varieties were infested under mulch and infested without mulch, the results showed that mulching overcomes the effects of infestation in some varieties. Mulch also negates the effect of Striga parasitism and results in yield maintenance in sorghum varieties. The third study sought to determine the stability of sorghum lines when exposed to two Striga asiatica lines sourced from two places which are 500 km apart in Zimbabwe. The two strains were termed the Chiundura and Rushinga strains, based on where they were sourced. The experiments were conducted at Henderson Research Station (HRS) at Mazoe and at Bindura University of Science Education (BUSE). The results showed differential virulence for some traits while the two strains were equally virulent for some traits. The two strains were equally virulent on all sorghum lines with respect to chlorophyll content. The different sorghum lines responded differently to the effects of the two strains. The effects of the two strains were generally similar for head index, root index, and leaf index at all sites. Generally the Chiundura strain was more virulent to sorghum lines compared to Rushinga strain, confirming the existence of physiological strains of Striga in Zimbabwe. Therefore physiological speciation of Striga asiatica exists and this adds a further dimension to the complexity of Striga management in the smallholder sector. Quantification of strigolactone production by different sorghum genotypes was conducted in the laboratory using the agar gel assay. The genotype Mukadziusaende produced significantly the least (P<0.01) quantities of strigolactones, as inferred from the maximum germination distance (MGD) from the sorghum root. The MGD was negatively correlated to tiller numbers illustrating that the more the strigolactones the less the tillering capacity. Tiller numbers and MGD can therefore be used to select for reduced strigolactones production.

- Description: The traditional employer-employee relationship came under an increased threat the past two decades with employers finding the option of utilising the services of Labour Brokers more attractive. Various reasons existed for this tendency amongst employers to opt for the use of Labour Brokers, some of these reasons being valid but mostly some reasons being born out of fear for the unknown labour law duties and obligations that were proposed to be placed on employers post 1994. In the absence of an action plan between the role players in the labour fraternity pathing the way traditional employer-employee relationships could be salvage, employers resorted to the appointment of Labour Brokers and Government on their part retaliated by considering either the total ban of Labour Brokers or the regulation of the profession to such an extent that same became largely unattractive and problematic. The non-addressing of problems and fears faced with by employers post 1994 resulted in an opportunity waisted to narrow the gap between employers and employees with the fight over work force power being the more important factor taken into consideration. This treatise will explore the options that faced the roll players post 1994 in the labour market, the reason for choices made and the effect same has had since on the labour market. The problematic amendments made to Section 198 of the Labour Relations Act in an attempt to iron out the wrinkles poor choices made by the stake holders over the regulations of Labour Brokers, will be discussed. The ripple effect the amendments to Section 198 of the Labour Relations Act had on other pieces of South African legislation will be considered and the uncertainty and confusion it has created discussed. Specific attention needs to be drawn to the intention of the legislature as to which party, the Labour Broker or employer, will be responsible for the ramifications of the wrong doings of an employee. Also, which party will be responsible to the employee to fulfil its labour rights as granted in the Constitution of South Africa. Unleashing reaction to the regulations of Temporary Employment Services does not seem to be a problem, the problem arises where the regulations proposed did not unleashed the desired reaction and roll players finding themselves frustrated and with having no alternative as to turn the Courts to solve the largely self-inflicted conundrum. The courts are left with the task of clarifying the legislature’s true intension in amending section 198 of the Labour Relations Act, which impact the writer with all due respect do not think the legislature even appreciated when the amendments were drafted. Currently, there is dividing views on the future of Labour Brokers per se in South Africa and the interpretation concerning Section 198 of the Labour Relations Act, as amended. The focus of this treatise is to highlight the different interpretations given to these amendments this far and highlight that if it is in fact the wish of stake holders in the Labour fraternity that Labour Brokers should continue to exist, clarification is needed by our Constitution Court on certain vital issues and as discussed in this treatise.

- Description: In recent years, there has been a rapid improvement in the way currencies are perceived, which has led to a rise in digital currencies commonly known as cryptocurrencies (because they are secured by the use of cryptography). Bitcoin was the _rst successful cryptocurrency which allowed users to transact directly with each other without the involvement of the third party (the bank). Bitcoin introduced a new technology known as the blockchain which is considered to be the ext-generation technology". Blockchain is a chronological database used to store all the transactions that have occurred since the inception of Bitcoin. A study of the Blockchain involving its application to the South African Social Security Agency (SASSA) is presented. This study assesses how the Blockchain functions. The Blockchain has been viewed as the next-generation technology. This study also assesses the application of the Blockchain to other systems other than cryptocurrencies or digital currencies. Recent studies in the literature have proposed applications of the Blockchain to other system (e.g. electronic voting, smart contracts, and intellectual property rights). Although these proposals have been put forward, none has been made speci_cally for SASSA. This study also presents the problems that the Blockchain has (e.g. scalability, security).Recent literature has tried to solve the problem of scalability, by introducing new protocols like mini-blockchain. In addition, this study presents the challenges that SASSA is currently having and it provides details about the attacks that could succeed in the system. The study presents the analysis of the blockchain for its application to SASSA; the analysis includes scalability, performance and security. Based on the analysis, it is shown that the blockchain is not compatible to be applied to SASSA. However, this study proposes a solution to some of the challenges SASSA is currently facing.

- Description: Invasive tree species pose a huge problem in the Garden Route and are particularly damaging to aquatic ecosystems, including wetlands, riparian zones, lakes and estuaries. Therefore, this study aimed to determine priority areas for invasive tree species management, with a focus on aquatic ecosystems. This was achieved by using existing literature to identify priority species, based on their impact on aquatic ecosystems and their associated ecosystem services, and then testing the suitability of SPOT-6 and WorldView-3 multispectral data at detecting these focal species. The priority species identified were: Acacia cyclops (rooikrans), Acacia longifolia (long-leaved wattle), Acacia mearnsii (black wattle), Acacia melanoxylon (blackwood), Acacia saligna (Port Jackson willow), Eucalyptus camaldulensis (red river gum), Pinus pinaster (cluster pine) and Pinus radiata (radiata pine). The Random Forest classifier on SPOT-6 data achieved an overall accuracy of 62.5% and this method was consequently deemed ineffective at separating invasive tree species from other tree species in the Garden Route. The overall accuracy of the WorldView-3 classifier was higher (78.9%) but the cost of the data limited the use of more images for the detection of the focal species throughout the Garden Route. Therefore, to identify priority areas for invasive tree management, criteria derived from existing literature were input into spatial conservation planning software. The analysis identified the: Saasveld section of the Garden Route National Park, the Wilderness Lakes, Knysna Forest, Knysna Estuary, Tsitsikamma Forest around Stormsriver and a disturbed area of fynbos southeast of Kareedouw as management priorities. Currently spatial conservation planning software proved to be cost-affordable and useful tool and is recommended for invasive tree management in the Garden Route.

- Description: The construction industry is one of the strategic sectors that drive the economic sustainability and competitiveness of any nation. However, the chronic business failure amongst the start-ups and Small, Medium and Micro Enterprises (SMMEs) in the construction industry globally is of great concern to economic prosperity for both developed and developing countries. This challenge is significantly high in the South African construction industry, where SMMEs account for 95% of the business entities, of which about 80% are most likely to exit from the market within their first five years of operation. Previous studies in this field centred on the factors that lead to construction-business failure. However, the actual operational elements of surviving SMMEs have rarely been addressed and are little understood. Thus, this research aimed to explore the strategic drivers that offer significant solutions to the challenges facing start-up contractors in the South African construction industry. The review of the related literature revealed the strategic drivers and business survival characteristics that foster SMME economic sustainability and competitiveness in the construction market. The qualitative research approach that is rooted in the phenomenological paradigm was adopted for this study. Port Elizabeth, located in the Eastern Cape Province of South Africa was the selected geographical scope for this research. Thirty-four (34) construction organisations were purposively selected from the Port Elizabeth construction industry development board (cidb) register of contractors in grades 4-6. The purposive sampling technique was adopted in selecting respondents based on the snowball approach. The research data were collected through in-depth interviewing. It was found that the SMME contractors who succeeded in their first 5 years of operation possessed the following qualities: “fundamental educational qualifications”; “experience and knowledge of construction works”; “a clear understanding of competitive business strategies and characteristics”; “critical skills and multi-skills (functional project teams)”; and “rely on strategic resources, competencies and capabilities”. Also, the significant factors contributing to the SMME contractors’ competitiveness were: “entrepreneurship skills”; “innovation and technological skills”; “leadership skills”; “education, skills training, and investment in Research and Development (R&D)”; as well as “strategic-alliance advantage”. Moreover, globalisation and internationalisation, and government support have significant potential to impact on the success and sustainability of SMME contractors. Unfortunately, these factors are under-utilised or un-strategically adopted by most of the South African SMME contractors. The research has also developed a conceptual model for sustainable performance of SMMEs based on the results and informed by the theoretical framework. The research has also developed a business-survival strategy and model for SMME contractors in the South African construction industry. The study has achieved its aim of identifying the strategic business practices, models and concepts that the surviving and active SMME contractors employed to thrive within and beyond the first five years in the industry. Based on these findings, the study recommends that the start-ups and SMME contractors should gain an insightful and strategic business knowledge on how to develop and grow a competitive and economically sustainable organisation in the industry. This should form part of their competitive business strategic models, their business review plans; and set the benchmark for performance evaluation.

- Description: The purpose of this study is to explore how Rhodes University (RU) students construct identity through the symbolic consumption of luxury branded clothing and the role played by reference groups in the consumption behaviour. The study employed the Social Identity Theory (SIT) as a theoretical framework which explains the underpinnings of the cognitions and behaviour with the use of group processes (Trepte, 2006). The central principle of SIT lies in individuals classifying themselves and others into in-group (reference groups) and out-group social categories respectively. There has been a gap in the literature pertaining to a full understanding of the identity construction process through symbolic consumption of luxury brands in South Africa (Reed, 2002). The significance of the study is to provide a foundation for an enhanced theory of consumer behaviour in this context. This study employed a qualitative research approach. A non-probability convenience sampling technique was used, and a total of 12 undergraduate and postgraduate students were interviewed. The chosen data collection method was semi-structured in-depth interviews and data were analysed using thematic analysis. The findings of the study revealed that participants consume luxury branded clothing for both functional and symbolic purposes. Various factors emerged that influence the choice of the symbolic consumption behaviour such as income, buying frequency, spending patterns, perceptions and habits around retail shopping and the shopping experience. In addition, results indicated that reference groups (celebrities, family and peers) play a significant role in the symbolic consumption and construction of identity among the participants. In addition, the results also indicated that the RU participants engaged in a ‘save to spend’ technique whereby they save their pocket money so that they spend it on their favourite luxury branded clothing when they leave for the holidays. There was a common reference group that emerged from the study, namely the peer in-group. The influence of reference groups on youth consumers in South Africa may assist with marketing strategies that can be employed when targeting the Generation Y. Additionally, results indicate that luxury branded clothing have an impact on identity construction within the South African context. The respondents tie their identity to their luxury branded clothing as an indication of ‘who they are’ and as an extension of the ‘self’.

- Description: This study evaluates the efficacy of the Bridges to the Future Initiative - South Africa 2 (BFI) tablet program on early literacy skills, as well as the ways in which learner-operated technology interacts with a traditional South African education system. The BFI is a curriculum-aligned early literacy development intervention implemented through technology in grades 2 and 3 in Northern Sotho1 first-language schools. A mixed-methods research design was utilized, involving three components: a literacy skills test administered through a time sequence trial design; a curriculum-aligned uptake and retention test using a pre-post design; and a qualitative research component including classroom observation, participant interviews and prompted drawings by learners. Paired sample t-tests show significantly higher gains during the treatment period in fluency and comprehension, and significantly higher gains in the control period in decoding individual words. It is theorized that this is due to teacher emphasis on emergent literacy. When initial ability is taken into consideration, all ability levels gain more on average during the treatment period in at least one measured skill. Regression analysis determines that time spent on the BFI program is not the most significant determiner of gains in the intervention period. Qualitative analysis supports this finding and suggests that program use cannot replace quality classroom practice in advancing literacy skills. Learners performed better after a delayed retention period than in an initial uptake test, indicating high rates of retention of knowledge gained through program use and traditional instruction, but inconsistent access to literacy skills gained.
