- Description: South Africa is the most unequal society on the planet, overwhelming Brazil, with a critical increment in wage inequalities. In a quest to reduce unemployment, this research is at the focal point of our nation's activity emergency. In any case, there ought to be components to ensure representation against oppressive work rehearses. The Labour Relations Act denoted a noteworthy change in South Africa's statutory modern relations framework. Following the progress to political majority rule government, the LRA embodied the new government's means to remake and democratize the economy and society as connected in the work relations field. Specifically, it presented new organizations went for giving managers and labourers a chance to break with the serious adversarialism that portrayed their relations before. In extending the equitable change, the Labour Relations Act which offered ascend to the foundation of the National Economic Development and Labour Council (NEDLAC) appeared on 18 February 1995, in an offer to add authenticity and straightforwardness to the financial basic leadership process. This research will investigate the law representing fixed term employment in South Africa. It will further give an investigation of the legitimate framework of fixed term representative keeping in mind the end goal to decide if it advances not too bad work in South Africa. This investigation intends to call attention to any substantive and procedural imperfections that might be accessible in the law. The study will likewise be taking the potential lessons which can be gained from different nations with comparative Fixed-term work challenges i.e. Namibia. This implies the examination will survey the current zone of law and propose an alternate approach. This will be finished by investigating important case law and enactments which secure settled term business. In certainty, the investigation intends to give new point of view regarding the matter of fixed term work and proffer a few changes to the law. , Thesis (MA) -- Faculty of Law, 2018

- Description: Despite the initiation of life-long ART in HIV-infected pregnant women, the rate and determinants of infant HIV transmission are not known, especially in the poor resource settings of the Eastern Cape, South Africa. Maternal anti-retroviral therapy (ART) is crucial for elimination of mother-to-child transmission (MTCT) of HIV. However, the inevitable risks of emergence of HIV drug resistance poses significant threat to achieving this goal of HIV-free generation and keeping mothers alive. Also, it is unclear if women with high viral load at delivery have acquired clinically relevant mutations, which could confer resistance to the ART, thus, further increasing the risks of motherto- child transmission of HIV-drug resistance strains. In addition to the gaps identified in the prevention of mother-to-child transmission (PMTCT) context, the understanding of regional epidemics is crucial to the broader epidemiological profiling of HIV infections in the country. Despite the rapid influx of foreign nationals to South African and Eastern Cape Province, there has not been any molecular epidemiological studies profiling the HIV diversity in the Eastern Cape. , Thesis (PhD) (Microbiology) -- University of Fort Hare, 2018

- Description: The purpose of this study was to investigate the barriers to collaborative culture of teaching and learning in selected high schools in Libode, O.R Tambo Coastal Education District. The literature review looked into each of the following aspects of teacher collaborative culture of teaching and learning in schools: theoretical framework, significance of changing the culture of teaching and learning and in schools, the nature of teacher resistance in collaborative teaching and learning in schools, the nature of teacher collaborative professional development activities in schools, the existence of collaborative learning culture in schools, leadership in collaborative culture of teaching and learning. This study was qualitative in nature and employed case study as the research design. The convenient sampling strategy was used to select three (3) high schools in Circuit 9 and 10 in Libode, O.R Tambo Coastal Education District. Four (4) teachers and one (1) principal were purposefully selected from each school the 3 schools and this made a total of fifteen (15) participants. Face-to-face individual interviews were conducted to gather data about the view points and opinions of the participants concerning the barriers to collaborative culture of teaching and learning in selected high schools of Libode, O.R Tambo Coastal Education District. Data collected was analyzed using the interpretational analytical strategies. Themes were drawn from the responses of the participants and analyzed. Some of the findings were that: There was inadequacy of positive attitudes towards collaboration with other teachers in the process of teaching and learning, teacher resistances was a barrier to collaboration in schools, there were inadequate collaborative strategies to provide the social, emotional, and intellectual engagement among teachers, knowledge sharing among teachers was limited, there was prevalence of teachers who work in isolation and strongly protect their individualism without professional collaboration and school managers played inadequate role in maintaining a collaborative learning environment among teachers. The researcher made some recommendations towards ensuring effective and efficient teacher collaboration in the high schools of Libode, O.R Tambo Coastal Education District. , Thesis (M.Ed) -- Faculty of Education Sciences, 2018

- Description: Traditional notions of masculinity which give power and authority to one dominant form of masculinity in the contemporary era are under scrutiny as they are constantly being challenged through the emergence of alternative forms of masculinity. Through the use of Wanner’s novels, this work examines how South African masculinities are constructed, how they are challenged, and how alternative forms are negotiated. It unpacks Wanner’s depiction of hegemonic, thwarted, complicit and marginalised masculinities as it traces the diversity and fluidity of masculinities in these literary texts and the resultant alternative masculinities these novels propose. Furthermore, this work foregrounds the often taken-for-granted role of women and portrays it as the centre around which masculinities are constructed. This is achieved by probing deeper into the familial unit and looking at the traditional gender roles of women, taking into consideration that the South African constitution allows them either to stick to these roles or to choose from an array of career choices presented to them. It is suggested that instead of viewing masculinity as a standard uniform entity, it is profitable to perceive it as a heterogeneous entity, comprising of different versions which are determined by different factors. It is further suggested that the role of women in the construction of masculinities should be given recognition, as they seem to play a significant role in either inhibiting or promoting the transformation of masculinities through the choices they make. , Thesis (M.Arts) -- Faculty of Humanities, Social Sciences and Law, 2018

- Description: This study is located in the field of education, within the domain of Continuing Professional Development CPD and curriculum. The study sought to assess the role of CPD in the transformation of health practice. The media’s complaints about poor service delivery within spheres of government, from local up to national level, triggered interest in a study of this nature. Since the Department of Health falls amongst the essential services, research on current public healthcare with the intention of transforming its practice was seen as imperative. An Advanced Diploma in District Health Management and Leadership ADDHM & L offered by Health Sciences at the University of Fort was used as a case. The healthcare practitioners who attended the stated programme were studied as a second case. The setting is in the public health care centres in the Department of Health within the Amathole region and Nelson Mandela Bay Metropolitan Municipality. An interpretive paradigm was used to ordain the study, the three sets of data were collected from various categories of participants such as graduates of the ADDHM & L programme, their workplace supervisors, as well as the facilitators of the programme. The last set of data was collected from the ADDHM & L documents. Interviews and questionnaires were used as data collection tools and thematic analysis was used for data analysis. The findings revealed that curriculum development and design has a strong bearing on formal continuing professional development programmes. For such programmes to be able to transform practice, the curriculum pedagogies should be designed and developed in such a way that the learning taking place is authentic in nature. It is this type of learning that will influence reflective practice and translation of knowledge. The findings also revealed that institutions of higher learning do play a crucial role in closing the gap that exists between theory and practice through designing programmes that are pedagogically aligned towards authentic learning. The learning instructions, the experiences, the expectations of the learner, the assessment forms that influence the nature of tasks and activities given by facilitators can either enable or hinder the ability to transform practice. , Thesis (PhD) -- Faculty of Education, 2018

- Description: Impacts associated with climate variability and extreme heat are already obvious in varying degrees and expected to be disruptive in the near future across the globe especially in the urban regions. Urban areas have distinctive features that leave their residents and properties vulnerable to extreme climate events. Global temperatures continue to change, reaching new levels almost every year for the past two decades. However, even though the causes are debated it is evident that climate variability is real. Climate variability and disaster risk are threats to human health that adversely reinforce each other. Better knowledge on the association between climate change, variability and extreme weather-related illness is needed and can aid strategies to reduce vulnerabilities. The impacts of climate variability on the health of residents in East London (EL) area in the Eastern Cape Province, South Africa were explored through four interdependent research segments. The first section examined the climate variability and urban surface thermal characteristics implication on human health using Remote Sensing (RS) and Geographic Information System (GIS) techniques. Remote sensing was used to assess the Land Surface Temperature (LST) and estimated Radiation (R) of East London area from Landsat Thematic Mapper (TM) images for 1986, 1996, 2006 as well as from Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) for 2016 spanning a period of 30 years. Rapid urbanization and land cover changes in this area have contributed significantly to this drastic change in the natural land surface characteristics (increased land surface temperature and surface solar radiation). For instance, vegetation cover declined by about 358.812km2 while built-up areas increased by 175.473km2 during this period which correlates with the area thermal characteristics changes. Radiation levels also increased over the years with values exceeding the global solar radiation index. Exposure to increased surface radiation poses risks of heat stroke, skin cancer and heart disease to the local population. Consequently, this study provides pertinent information on human health sustainability and epidemiological case management. The second part explored past temperature and humidity trends (1986-2016) and projects future trends (2017-2030). The historical data of meteorological variables were obtained from the archives of the South African Weather Service and analyzed using the ordinary least square regression model in GRETL (GNU Regression Econometric and Time-series Library) statistical software. This study discovered a local consistency between models and the observations add to existing knowledge and this is crucial in knowing the shifts in climatic change as well as recognizing variability and its conflicting effects on human health, environment, agriculture, ecological sustainability and socioeconomic status in the region. The third segment assessed the potential impacts of climate variability on health using existing heat indices during the study period. The results demonstrated that in East London from 1986 to 2016 during summer and autumn (December to May) of various years exceeded high heat index values. It is obvious that summer and autumn months are more vulnerable to heat extreme and humidex. The humidex and Heat Index (HI) increased annually by 0.03percent and 0.9percent respectively throughout the study period. The increment in the various indices showed highly significant ill-health and environmental impacts on humans especially with prolonged exposure. The last segment appraised the association between climatic elements and epidemiological incidences of the study area between 2012 and 2016. The epidemiology incidences data were obtained from the archives of the Cecilia Makiwane Hospital in East London area and National Tertiary Service Grant (NTSG) database for the period. The results have showed that there exists significant effects of climate variability on the health of East London residents and these have been identified to have negative impacts on health of the people in the area. This study also revealed noticeable impacts of extreme heat on human health and a positive correlation between meteorological components (HI and temperature) and epidemiological cases (cardiovascular, skin cancer and diarrhea) during the study period. , Thesis (PhD) -- Faculty of Science and Agriculture, 2018

- Description: The study sought to investigate records management programmes by small-scale farmers, focussing on small-scale farmers in Wesley Community in Eastern Cape South Africa. The objectives of the study were to: Determine the types of records kept by small-scale farmers in Wesley Community; Assess records the records management practices used by small-scale farmers in Wesley Community; Find out the benefits of managing farm records by small-scale farmers in Wesley Community; and Identify the constraints small-scale farmers in Wesley Community encounter in the management of their farm records. This study adopted both qualitative and quantitative research approaches. The researcher followed a methodological path that began with a thorough literature review and a careful and thoughtful posing of research questions and objectives. A sample of Wesley Community small-scale farmers was chosen using both convenience and snowball sampling where available and willing farmers were interviewed using questionnaires and in-depth interviews. Collected data were analysed using Microsoft Excel 2010. The study found that an encouraging number of small-scale farmers keep records. The records kept by small-scale farmers, however, some of them are not organised or being kept in a systematic way. Small-scale farmers do find record keeping very beneficial and are interested in keeping more records. Illiteracy and low self-esteem proved to be constraints when it comes to small-scale farmers’ records keeping and management. It was concluded that small-scale farmers do keep records. The manner in which the records are kept is mostly systematic. There a benefits of keeping records for farmers even though small-scale farmers face a few constrains when it comes to record keeping. From the findings it is recommended that: the government offer basic education classes for small-scale farmers, records management awards to motivate small-scale farmers and records management training for small-scale farmers. , Thesis (MLIS) -- Faculty of Social Sciences and Humanities, 2018

- Description: Background: Motivation is critical to health worker performance and work quality. In Bihar, India, frontline health workers provide essential health services for the state’s poorest citizens. Yet, there is a shortfall of motivated and skilled providers and a lack of coordination between two cadres of frontline health workers and their supervisors. CARE India developed an approach aimed at improving health workers’ performance by shifting work culture and strengthening teamwork and motivation. The intervention—“Team-Based Goals and Incentives”—supported health workers to work as teams towards collective goals and rewarded success with public recognition and non-financial incentives. Methods: Thirty months after initiating the intervention, 885 health workers and 98 supervisors completed an interviewer-administered questionnaire in 38 intervention and 38 control health sub-centers in one district. The questionnaire included measures of social cohesion, teamwork attitudes, self-efficacy, job satisfaction, teamwork behaviors, equitable service delivery, taking initiative, and supervisory support. We conducted bivariate analyses to examine the impact of the intervention on these psychosocial and behavioral outcomes. Results: Results show statistically significant differences across several measures between intervention and control frontline health workers, including improved teamwork (mean = 8.8 vs. 7.3), empowerment (8.5 vs. 7.4), job satisfaction (7.1 vs. 5.99) and equitable service delivery (6.7 vs. 4.99). While fewer significant differences were found for supervisors, they reported improved teamwork (8.4 vs. 5.3), and frontline health workers reported improved fulfillment of supervisory duties by their supervisors (8.9 vs. 7.6). Both frontline health workers and supervisors found public recognition and enhanced teamwork more motivating than the non-financial incentives. Conclusions: The Team-Based Goals and Incentives model reinforces intrinsic motivation and supports improvements in the teamwork, motivation, and performance of health workers. It offers an approach to practitioners and governments for improving the work environment in a resource-constrained setting and where there are multiple cadres of health workers.

- Description: Fluvial systems are dynamic systems in which variables in a catchment and river channel affect the morphology of river reaches. South African rivers are increasingly being exposed to stresses from a combination of factors, one of the most prevalent being the impacts of damming rivers which result in varying downstream sediment fluxes and flow regimes. The sediment load combined with flow characteristics for respective river channels provides the physical habitat for aquatic ecosystems. The damming of the Tsitsa River, through the construction of the Ntabelanga Dam, will change the overall downstream geomorphology. This creates an opportunity for research in the preconstruction window. The current condition of the Tsitsa River was monitored by completing a baseline survey of the channel geomorphology with specific reference to the influence of sediment on river habitats and ecosystem health. Five sites were established in variable reaches of the Tsitsa River, with Site 1 located above the proposed Ntabelanga Dam inundation and Sites 2-5 below the proposed dam wall. Each site included a range of features that can be monitored for their response to the dam. Physical variables, water quality and biota were monitored seasonally to note changes in habitat quality. A baseline survey of the present geomorphology and associated instream habitats of the selected reaches was set up by conducting cross-sectional surveys of channel topography, water slope surveys, discharge measurements and visual and quantitative assessments of substrate. Level loggers were installed at each site to collect continuous data on variations in depth and temperature. Monitoring surveys, in terms of fine sediment accumulation, were conducted to characterise dynamic habitat arrangements and macroinvertebrate community composition. A taxa related physical habitat score for the Tsitsa River was created. The relationship between water quality, physical and ecological characteristics of the Tsitsa River will aid further research in the area as well as create a better understanding of the influence of sediment on river habitats and ecosystem health. Monitoring sites can be used to monitor the impact of catchment-wide rehabilitation on river health prior to the dam being built. After dam construction, the top site above the dam inundation can still be used as a point to monitor the impact of catchment rehabilitation on ecosystem health in terms of fine sediment accumulation.

- Description: This study set out to explore and describe in the form of a qualitative case study, an iteration of a Fundisa for Change teacher professional development programme, in this case the Teaching Life & Living short course presented to seventeen teachers as part of their Advanced Certificate in Teaching (ACT) Senior Phase Natural Sciences, at the University of Cape Town. The focus of the research was on describing how the development of teacher environmental pedagogical content knowledge (PCK) was supported and constructed in the course. The Consensus Model of Teacher Professional Knowledge and Skill, an outcome of the 2012 PCK Summit, was used to define the concept of PCK and also contributed the concept of amplifiers and filters as processes that mediate the development of teacher PCK. The study drew on Borko’s (2004) model of a professional development system, using the elements of course, teachers, facilitators and context as an analytical framework. Data generated included a teacher contextual profile questionnaire, audio-recordings of group work, course outputs and reflection and evaluation forms. Data analysis had two phases: the first phase concentrated on the development of analytic memos based on particular data sources whereas the second phase worked across data sources to present the evidence relating to each of the professional development system elements. The study found that teachers were supported in the development of their environmental PCK by the collaborative learning opportunities afforded by the course. Emergent PCK was organised according to five components: assessment knowledge; pedagogical knowledge; content knowledge; knowledge of learners; and, curricular knowledge. Emergent teacher learning ranged in specificity from general, to subject-specific, to domain-specific, and lastly to topic-specific knowledge. Teacher beliefs and orientations, prior knowledge and contexts brought into the professional development system were described as amplifiers and filters to teacher learning of PCK. In particular there were several contextual factors that emerged as themes from the data that had potentially filtering effects. Recommendations included that facilitators create an atmosphere conducive to collaborative learning, that evidence of learner conceptual understanding be examined during the course, that teachers be exposed to in-depth examples of canonical PCK and that more modelling of formative assessment strategies are presented.

- Description: This case study research on the effect of leadership on organizational culture, is based on a small luxury tourism organization – Belmond Safaris – based in Maun, Botswana. The study set out to determine critical incidents that occurred during the tenure of the current general manager with the intention of uncovering her leadership behaviour and how it has shaped the culture of the organization. The literature review identified quantitative and qualitative approaches to researching organizational culture, but settles on Schein’s theory of organizational culture (Schein, 1992; 2010) as the approach adopted in this study. Furthermore, it reviews the various roles of strategic leaders and how these affect the culture of the organization. The study follows a qualitative methodology and applies the Critical Incident Technique to explore how, as a leader, the behaviour of the general manager shaped the organization’s culture. Data triangulation is achieved through the use of multiple sources – interviews, analysis of company documents and the examination of minutes of management meetings. Following the fieldwork, the evidence within the findings of the study required a theoretical reorientation and a shift from strategic leadership to a new focus on relational leadership, highlighting the prominence of social exchanges between the general manager and employees, as opposed to economic exchanges. The study concludes by acknowledging the limitations and delimitations of the study, which include time constraints as well as the deliberate exclusion of certain participants (e.g. camp managers) from the study. In its conclusion the study also presents recommendations for future studies. The researcher recommends a broader study within the tourism industry, as well as a larger and more inclusive sample size, in order to obtain better insights into the study of culture and leadership within organizations.

- Description: This article makes the point that African states with significant strategic resources and democratic governance systems bargain better in economic and development assistance engagements with China and other partners. In democratic African states, non-state actors play critical complementary roles to the state, leading to multi-faceted forms of African agency. For non-democratic states, a significant limiting factor in their agency is the lack of working relationships between the state and non-state actors. Concomitantly, such states find themselves with weak bargaining and negotiating capacities. If African agency is to be assertive, then state and non-state actors should work together when engaging external partners.

- Description: The term “trade” is defined in very wide terms in the Income Tax Act and includes a “business” and a “venture”. For a taxpayer to claim certain deductions in arriving at taxable income, the taxpayer must be carrying on a trade. The expression “carrying on a trade” is not defined in the Income Tax Act. Whether or not a taxpayer is carrying on a trade is a matter of fact. Case law has established certain principles and tests to be applied in determining whether a taxpayer is carrying on a trade. The goal of the thesis was to determine to what extent an activity can be considered as carrying on a trade. This research focused on the letting of property, money-lending, or farming operations in relation to carrying on a trade or business or engaging in a venture. The thesis also discussed at what stage a taxpayer ceases to carry on a trade and what the tax consequences are of ceasing to trade. An interpretative research approach was used in the research as it sought to understand and describe. No interviews conducted for this research and the data used for the research are publicly available. It was established that “carrying on a trade”, including a business, requires an active step taken by the taxpayer to trade. It involves regularity of buying and selling or rendering of services. The intention to trade is important but it is a subjective matter and cannot be persuasive in determining whether a taxpayer is carrying on a trade; objective factors are also considered. If the stated intention to trade matches the actions of the taxpayer, the taxpayer will be considered to be carrying on a trade. In determining whether a taxpayer is carrying on a trade each case must be considered with its own merits.

- Description: The term “trade” is defined in very wide terms in the Income Tax Act and includes a “business” and a “venture”. For a taxpayer to claim certain deductions in arriving at taxable income, the taxpayer must be carrying on a trade. The expression “carrying on a trade” is not defined in the Income Tax Act. Whether or not a taxpayer is carrying on a trade is a matter of fact. Case law has established certain principles and tests to be applied in determining whether a taxpayer is carrying on a trade. The goal of the thesis was to determine to what extent an activity can be considered as carrying on a trade. This research focused on the letting of property, money-lending, or farming operations in relation to carrying on a trade or business or engaging in a venture. The thesis also discussed at what stage a taxpayer ceases to carry on a trade and what the tax consequences are of ceasing to trade. An interpretative research approach was used in the research as it sought to understand and describe. No interviews conducted for this research and the data used for the research are publicly available. It was established that “carrying on a trade”, including a business, requires an active step taken by the taxpayer to trade. It involves regularity of buying and selling or rendering of services. The intention to trade is important but it is a subjective matter and cannot be persuasive in determining whether a taxpayer is carrying on a trade; objective factors are also considered. If the stated intention to trade matches the actions of the taxpayer, the taxpayer will be considered to be carrying on a trade. In determining whether a taxpayer is carrying on a trade each case must be considered with its own merits.

- Description: Coastal ecosystems are more than microhabitats for marine species. Acting as atmospheric carbon filters, species in coastal environments are directly and/or indirectly associated with transferring organic carbon to species at higher trophic levels. However, the progressing change in global climatic conditions has created the need to assess the consequences of the shifting conditions on both direct and indirect interactions of physical and biological parameters at species and/or community levels. From these perturbations, the effects of biotic homogenization on ecosystem functioning and resilience can also be realised. Herein, I discuss the effects of temperature, nutrients, biotic interactions and habitat characteristics on community dynamics within intertidal rock pool systems on the south coast of South Africa using complementary qualitative and quantitative analytical methods. Seasonality had a significant impact on rock pool species with changes in composition and higher richness in winter than summer. The first two axes of the Canonical Correspondence Analysis (CCA) of the plant and animal communities each explained ~20% of the relationship between physico-chemical parameters and biological variables. The CCA highlighted that seasonal shifts in chlorophyll-a, conductivity, salinity, water depth, surface area and substratum type indirectly influenced species composition. For example, pools with heterogenous substratum comprising a mixture of sand and rock exhibited higher species diversity than homogenously bedded pools. Furthermore, a Bayesian analysis of community structure based on stable isotope ratios was used to assess how trophic pathways of carbon and nitrogen elements reflected community composition and richness. Isotopic biplots showed an increase in food web size, food chain length and the trophic positions of fish and some gastropods in winter compared to summer. There was greater dietary overlap among species in larger pools. In addition, while isotopic nearest neighbour distance and species evenness also showed a positive increase with pool size in summer, the same metrics were almost constant across all pool sizes in winter. These changes in food web packing and species evenness suggest seasonal preferences or migration of species in summer from small pools to larger pools with stable physico-chemical parameters. Furthermore, the presence of fish was seen to promote trophic diversity within some pools. The results from laboratory microcosm grazing experiments demonstrated significant direct and indirect effects of temperature and nutrients within plankton communities. Copepod grazing had an indirect positive influence on phytoplankton biomass and size structure while the interactive effects of temperature and nutrients had contrasting effects on both phytoplankton communities and copepod biomass. Shifts in water chemistry and nutrient treatments were also observed in the presence of copepods. Phosphate addition had a recognisable impact on plankton communities. The presented synthesis of the literature mainly highlighted that positive effects at one trophic level do not always positively cascade into the next trophic level which is evidence of complex interactive biotic, habitat and water chemistry effects within these intertidal ecosystems. Thus, to further understand cascading effects or community structure functioning in general, there may be a need to incorporate and understand species functional traits and how they contribute to trophic diversity, community restructuring and functioning in coastal habitats.

- Description: In the South African context, it is accepted that small businesses will be the vehicle for job creation and changing the current business ownership patterns. This is to be achieved by creating access to finance, exploring the role of venture capital and simplifying the tax obligations and the compliance burden. The literature indicates that the current South African tax incentives for small businesses are perceived as unfair and fundamentally ineffective. The objective of this thesis was to compare the tax incentives available to small businesses and investors in small businesses in South Africa to those available in Australia, New Zealand, Singapore and Ireland, in order to identify possible measures that could be introduced in South Africa. In addressing the objective, the research set out to provide, in terms of South African tax legislation, a definition of a small business for tax purposes and document the tax incentives available for start-up and existing small businesses, as well as the tax incentives available for investors in small businesses, either through a venture capital company or a direct investment in small business. It was found that South Africa has a complex and onerous multi-layered approach to classifying a taxpayer as either a “micro business” or a “small business corporation” for the purpose of applying tax incentives. The international jurisdictions included in this research follow a single requirement approach, based on either one or a combination of turnover, balance sheet total or staff headcount. The international jurisdictions provide a wide range of tax incentives to small businesses and investors in small businesses, aimed at reducing taxable income to enable the small businesses to grow and access equity finance. By identifying differences and similarities, a number of possible tax relief measures were recommended that could be introduced in South Africa.

- Description: Every day, computer networks throughout the world face a constant onslaught of attacks. To combat these, network administrators are forced to employ a multitude of mitigating measures. Devices such as firewalls and Intrusion Detection Systems are prevalent today and employ extensive Deep Packet Inspection to scrutinise each piece of network traffic. Systems such as these usually require specialised hardware to meet the demand imposed by high throughput networks. Hardware like this is extremely expensive and singular in its function. It is with this in mind that the string search algorithms are introduced. These algorithms have been proven to perform well when searching through large volumes of text and may be able to perform equally well in the context of Deep Packet Inspection. String search algorithms are designed to match a single pattern to a substring of a given piece of text. This is not unlike the heuristics employed by traditional Deep Packet Inspection systems. This research compares the performance of a large number of string search algorithms during packet processing. Deep Packet Inspection places stringent restrictions on the reliability and speed of the algorithms due to increased performance pressures. A test system had to be designed in order to properly test the string search algorithms in the context of Deep Packet Inspection. The system allowed for precise and repeatable tests of each algorithm and then for their comparison. Of the algorithms tested, the Horspool and Quick Search algorithms posted the best results for both speed and reliability. The Not So Naive and Rabin-Karp algorithms were slowest overall.
