- Description: When the Arab Spring took place, it took the world by surprise and sparked renewed interest in the idea of revolution. With differing opinions on what caused such a revolutionary wave throughout the North African and Middle Eastern region, many began looking at their own countries, and South Africa was no different. A debate was sparked in South Africa, as to whether there would be a revolution or not. What I originally set out to accomplish is to find out which side of the debate would be correct through the philosophical context of revolutionary theory. Initially, we attempted to define and consider the history of revolutionary theory. We found that revolutionary theory has gone through four generation and that even finding a theoretically informed definition is difficult. Following this, we considered some social-psychological theories of revolution as well as theories of moral indignation. We found that these theories were incredibly informative and that they provide some insight into the reasoning for revolutionary fear in the South African debate. Through the use of opinion pieces, we then considered the South African debate, and – using socialpsychological theories and the theories of moral indignation - found that both sides of the argument had valuable points, however, they often lacked some foresight. With tentative agreement, we found that the side arguing that there would a revolution in South Africa had a more valuable argument, despite its limitations. However, far more research is required before one can – with more accuracy – predict a revolutionary occurrence in such a way as was done in South Africa.

Translating Heaney: a study of Sweeney astray, The cure at Troy, and Beowulf

- Description: This thesis examines Seamus Heaney’s approach to translation with specific reference to Sweeney Astray, The Cure at Troy, and Beowulf. An assessment of Heaney’s translations, and the ways in which they relate to his poetry, is essential to an understanding of his work as a poet. This thesis demonstrates the centrality of translation to Heaney’s oeuvre as an effective means to comment on his Northern Irish socio-political context without producing political propaganda. Translation is a valuable means for Heaney to elucidate his contemporary experience by considering it in terms of the recorded past captured within his chosen translations. Instead of comparing the three translations with their original texts, this thesis concentrates on Heaney’s translations as a continuation of his own creative work and as catalysts for further poetry. The translations are explored in chronological order to allow a sense of Heaney’s development as a translator and his efforts to remain critically attuned to the Northern Irish political situation. The first chapter examines Heaney’s translation of the Gaelic poem Buile Suibhne, which is published as Sweeney Astray. In this first major act of translation Heaney recognises the political role that translation is able to play. He draws attention to the protagonist’s sense of cultural ease in both Britain and Ireland, which he argues is exemplary for the people of Ulster and renders the narrative particularly accessible to a Northern Irish readership due to his anglicisation of the text, which is intended as a reminder to both Catholics and Protestants of their shared identity as Irishmen. The second chapter focuses on Heaney’s translation of Sophocles’ Philoctetes, entitled The Cure at Troy. Heaney’s translation contextualises the Ancient Greek concern for personal integrity in the face of political necessity, a situation relevant to his own complex relationship with Northern Irish politics. His alterations to the text accentuate the positive aspects of the play, suggesting the very real possibility of social change within the seemingly constant violence of Northern Ireland. The third chapter explores Heaney’s engagement with the Anglo-Saxon epic poem, Beowulf, as a means of coming to terms with the complex history of Irish colonisation through language. This chapter assesses Heaney’s incorporation of Irish dialectal words into his translation, which lend the poem political weight, and yet prove to be contextually appropriate, rendering Heaney’s Beowulf a masterpiece of readability and subtle political commentary.

- Description: The aim of this research is to evaluate the level of service quality provided by Eskom to its Large Power User (LPU) customer segment in the Eastern Cape. The research uses the SERVQUAL model in order to assess the customers’ expectations and perceptions of the service provided by Eskom. This evaluation report comprises three sections. Section one consists of (a) a review of service quality literature that exists and is applied to Eskom where relevant, (b) a summary of the method used to conduct the research, (c) the research findings, and (d) a discussion of the research findings and recommendations. Section two consists of a review of the key concepts identified for this study as follows: (a) defining customer service quality by looking at the concepts of the customer, service, quality and the dimensions of quality, (b) the importance of service quality, (c) the components of service quality in Eskom, (d) models of service quality, and (e) the SERVQUAL model used in this study. Section three consists of the detail of the research methodology used to conduct this study. The Gap Model of Service Quality (Parasuraman et al., 1985:44) is evaluated in order to understand the gaps between expected and perceived service. The provider gap (Zeithaml et al., 2006: 34) is also reviewed in order to identify the gaps that occur within the organisation. An extensive review of customer service quality models is undertaken before a discussion of the SERVQUAL model, which was used in this evaluation study, is provided. The researcher adopted the critical realism research paradigm and quantitative data was collected from a sample of 120 Eskom customers within the LPU customer segment in the Eastern Cape. These customers were randomly selected from the Eskom Customer Care and Billing database and comprised customers from Port Elizabeth, Aliwal North, Mthatha and East London Areas within the Eastern Cape. The data was collected online through a questionnaire which was based on SERVQUAL and modified for electricity services. The quantitative data obtained from the study is presented in the form of tables and graphs created from the data obtained from the 45 customers who responded to the questionnaire. The gaps between LPU customer perceptions and expectations were calculated for the five SERVQUAL dimensions. The research identifies the existing gaps in the service delivered by Eskom; this is based on the perceptions and expectations of the LPU customers in the Eastern Cape, who participated in the study. The results reveal that gaps exist between LPU customer perceptions and their expectations of the service provided by Eskom in the Eastern Cape. The key findings reveal that the largest gaps are within the reliability and empathy dimensions and the smallest gap is in the tangibles dimension. The recommendations were made on the basis of the gaps which were identified and these focus on the training of the front line staff responsible for servicing customers. It is recommended that this training should include an overview of the organisation’s policies and procedures to enable employees to respond adequately to customer queries. Recommendation is also made on training staff to interact with customers effectively in order to resolve customer queries satisfactorily. Finally, it is recommended that regular assessments of the existing customer service quality levels are conducted in order for the organisation to remain aware of the current customer perceptions and expectations

- Description: This study builds on South African cross-cultural research which highlights the need for careful stratification of normative samples for quality of education and geographical location. The aim of the present study was to produce an expanded set of preliminary norms for learners in the disadvantaged schools of the peri-urban areas of the Eastern Cape, Grahamstown, on the Vassiliou Mathematics Foundation Phase Test (VASSI) and Vassiliou Mathematics Proficiency Test (VASSI), respectively. The test was administered to Grade 1-6 learners in four different schools all within Joza location, Grahamstown. For the learners’ convenience the tests were translated into isiXhosa, the translations were provided together with the original English questions. Archival data collected by honours students was also incorporated in this study. The total number of participants was N=724 which was comprised of 147 grade 1s, 123 grade 2s, 117 grade 3s, 128 grade 4s, 113 grade 5s and 96 grade 6s. Norm-referenced criterion was used in analysing the data. The results of this study are in accordance with those purporting the low performance of disadvantaged learners on the school subject, mathematics. Stanines for the various grades (Grade 1 to 6) were calculated and are presented in the study. This study has demonstrated that although gender, language and other ethnic variables have an impact on mathematics performance, quality of education and socioeconomic status have a significant effect. Further research is needed on the effect of quality of education and socioeconomic status on learners in disadvantaged schools on this test in particular.

How the South African print media cover economics news: a study of inflation news in four newspapers, 1999-2001

- Description: There is a considerable amount of literature arguing that economics and business journalism is growing. This subfield of journalism is important as economics issues impact on everyday lives of the people. Media have an important role to inform people about the economy and give them a voice to take part in public debates. The down side though is that economics journalism is criticised for not serving the public well in this aspect. Evidence suggests that economics journalism lost its critical character and that there is closer in economics debates. Using content analysis, this study examines coverage of inflation as reported by South African print media. Three major findings emerged: 1) Evidence shows that there are a variety of cases of inflation. 2) There are also similarities among newspapers on what they view as causing inflation. 3) However, media do not draw sources from all sectors of society. The elite, who are educated people and government officials, are over-accessed while the ordinary citizens - although also affected by inflation – are marginalized. Company and government sources top source lists in the media. It is argued that sources play an important role in shaping the news content. They do so by identifying problems and prescribing potential solutions. They set parameters and define terms of reference. However, media also play a mediating role. They do so by selecting sources and structuring sources in stories. They may chose to quote or report what their sources say and even comment on it. This study concludes that in South Africa ordinary citizens have no voices in economics debates. Media used bureaucratic sources only and that is a consonant agenda on inflation coverage amongst newspapers. The heavy reliance on bureaucratic sources and the exclusion of some sectors of society in sources lists raises questions about impartiality of these sources on issues relating to their organisations and institutions. These are not viable sources that could provide information that could expose abuse of power.

Moving between the surreal, the absurd, the allegorical, and the metafictional, they elaborate on life's ordinary madness and the mysteries of the spirit. By challenging the either/or boundaries of the binary of realism and fantasy, the stories provoke the reader to engage actively with the text. Influenced by experimental US author Stacey Levine, the mid‐century British novelist Barbara Comyns, and the adventurous Chinese writer Can Xue, in most cases, they create a playful, experimental world that exists at a slight angle to the world as we know it.

- Description: In this thesis the long-term sustainable yield of the Karoo sediment aquifer unit occurring in Dendera area of Kwekwe District is investigated, with the object of providing quantitative data on the sustained availability of groundwater for small-scale irrigation projects. Archaean Basement Schists and Pre-Cambrian gneissic granites, the Basement Complex rocks, underlie the entire study area. Overlying these are Upper Karoo sediments. Aeolian Kalahari sands unconformably mantle higher interfluves, while redistributed sands occur along valleys of major rivers and streams. The Karoo sediments, which predominantly consist of loosely cemented, fine- to medium-grained sandstone alternating with red siltstone and mudstone, constitute the main aquifer. The thickness of the Karoo sediment unit ranges from 30m to 80m. The hydraulic parameters of the Karoo sediment aquifer were characterised in the field by constant discharge pumping tests and slug tests. Pumping tests indicated unconfined conditions and thus the Neuman's method of analysis has been used. Transmissivities from pumping tests are within the range 4.7 m²/d to 13.6 m²/d with an average of 8.9m²/d. The low transmissivities seem to be a major limiting factor in the exploitation of the groundwater resources. Thus the sustainable borehole yields tend to be small, mean values ranging from 33 m²/d to 253 m²/d. Specific yield could not be determined from the pumping tests due to the lack of observation boreholes. Low chemical concentrations render the water suitable for irrigation of all crops, while neither total nor any individual concentrations present health hazards to human or livestock. An average recharge value of 47.7 mm/y was inferred from water table fluctuation method. Chloride mass balance technique in the same area indicates recharge value in the order of 67.4 mm/y. Because the chloride mass balance gives a long-term mean annual recharge, the recharge figure of 67.4 mm/y was adopted for the study area. Based on the abstractable proportion of recharge, the sustainably exploitable volume of groundwater of the order of 2.68 x 10⁷ m³/y was established. This volume is more than 100 times the estimated current demand for groundwater (1.35 x 10⁵ m³/d), implying that there are large volumes of surplus water, which can be utilised for irrigation.

- Description: The world has seen unparalleled pressure put on the public sector to improve the speed and quality of service delivery, whilst simultaneously employing measures to cut the costs. South Africa and the Eastern Cape have not been immune to this as there have been complaints and demonstrations from various national and provincial stakeholders demanding more and improved services. The Department of Economic Development, Environmental Affairs and Tourism (DEDEAT) in particular has employed the services of public entities in its quest to realise government’s socio-economic developmental objectives and ease some of the service delivery pressures. These agencies are unfortunately struggling to deliver and the Department is unable to play the oversight role it is legislatively mandated to carry out. The main reason for this seem to be the lack of the capacity to objectively track and measure the performance of these agencies. As they say “you cannot manage what you cannot measure”. This is despite the fact that there is a shareholders’ compact and many other measures in place to enable performance monitoring. Also, the public sector is known to have inherent and unique performance management challenges like broad and vague objectives which lead to too many measurements, a propensity to focus on the “easy to measure” but often irrelevant indicators at the expense of critical outcomes and a short-term orientation that is usually fuelled by political expediency. Against this background, this study sought to make use of a comprehensive and dynamic performance monitoring framework, namely the Balanced Scorecard (BSC), to explore its potential use in assisting government to monitor the performance of public agencies, in particular the Development Finance Institutions (DFI) in South Africa. The proposed framework helps government to focus on the performance drivers of future value, and what decisions and actions are necessary to achieve critical outcomes. The aim of the study therefore is to develop an adjusted BSC framework to monitor the activities of a public sector agency and thus demonstrate how a BSC framework could be used to monitor a public agency by the government department. The study is evaluative in nature and is divided into three sections. Section one is presented as an Evaluation Report. It sets the scene, discusses briefly the key theoretical concepts, outlines the research methods used and presents the findings followed by a discussion and recommendations. Section two delves into the literature in more detail, providing a more extensive review of the literature that informed the investigation, whilst section three provides a more extensive description of the research methodology employed in the study. To achieve the aims of the study, the research drew from the work of various authors in the field including that of Bigliardi, Dormio and Galati, 2011; Bititci, Garengo, Dörfler, and Nudurupati, 2012; Julyan, 2011; Kaplan and Norton, 1992, 1993, 1996, 2001, 2004 and 2006; Niven, 2003 and 2008 and Northcott and Taulapapa, 2012. Also, five BSC perspectives - including the programme specific “equity” perspective - were used to develop an interview schedule. These were used to formulate the key performance objectives and indicators, based on the stakeholder’s responses. These respondents have experience within the programme as administrators, beneficiaries and funders. The research employed purposive sampling with semi-structured in-depth interviews and document analysis as primary and secondary instruments for data collection. In essence, five officials from the agency, one from DEDEAT and two co-operatives participated in the research. The results indicate a general appreciation of and gravitation towards outcome based measures, even though the government culture of focusing on outputs is still prevalent. The results of the study indicated that, generally, a government - public agency BSC based performance monitoring framework would have the following features: Customer objectives and programme mission as the main goal and this will provides clarity at all levels on who the customers are and what are their primary requirements. Clear, visible and stringent financial controls as the agency is administering public resources. Few carefully selected processes and systems that have a direct and positive impact on the customer objectives. Deliberate and consistent efforts to promote the participation of designated groups in the economy of the country. Comprehensive indicators on capacity building as “mission based-organisations rely heavily on skills, dedication and alignment of staff”. Overall, the study concludes that the make-up of the BSC is beneficial to the public sector and in monitoring the public sector agencies for the following reasons: It helps the agency to focus on customers and their needs. It forces the agency to engage and communicate strategic intention with both internal and external stakeholders and thus synchronize competing stakeholder needs. It forces the agency to limit the number of indicators and therefore select the few value adding measures that are aligned to customer outcomes. Through its cause and effect relationship, the agency is compelled to align all the resources, activities and processes to the main goal of the entity. All these help to minimize the principal agent problem, as the use of the BSC can bring clarity on strategy and expectations, provided it is supported with regular communication.

- Description: From Introduction: With the rapidly growing knowledge on trace elements and their influence on plant nutrition the need for accurate and rapid methods for their determination arose. The essential plant nutrients are usually divided into two groups. The major or macronutrient elements, necessary in comparatively large amounts, and the trace or micro-nutrient elements. In the case of plants, the first group includes Sulphur, Phosphorus, Potassium, Magnesium, Calcium and Nitrogen. The essential trace elements are Iron, manganese, Boron, Copper, Zinc, Molybdenum and Chlorine. Cobalt is essential for animal nutrition as a constituent of Vitamin B₁₂, but its essentiality for plants has not yet been proved. The latter group consists of metals which are catalysts in enzyme reactions and whose presence in the plant in minute amount determines whether the plant will be able to complete the vegetative or reproductive stage of its life cycle. Molybdenum may be quoted as an example of an essential trace element. It is generally recognised to be the catalyst responsible for the fixation of Nitrogen.

- Description: This study looks at the impact of elephant feeding on the Xeric Succulent Thicket component of Eastern Cape Subtropical Thicket (ECST) in Addo Elephant National Park (AENP). Observations of elephant feeding were carried out and vegetation transects were surveyed for impact of elephant feeding. The results indicated that the Nyati elephants spent the majority of their time grazing (nearly 90%), particularly the cow-young herds, and especially when the herd gathered in larger numbers. Browsing events were concentrated on Acacia karroo (81%) and there was no significant difference between the sexes in their preference for this species. Despite being subjected to most of the browsing, the majority of A. karroo trees were undamaged and the effect of elephants was generally light. It appears unlikely that, three years after re-introduction to Nyati, the elephants have had an effect on community structure of the vegetation. Surveys were conducted on stands of the alien invasive weed prickly pear Opuntia ficus-indica, and it was recorded that elephants in Nyati have had a dramatic effect on prickly pear, utilising all adult plants assessed and destroying 70% of them. This level of destruction in such a short period of time suggests that prickly pear is a highly favoured species. The results from the present study suggest that elephants can play a role in the control of prickly pear. Results are discussed in terms of elephants as both megaherbivores and keystone species, and as agents of intermediate disturbance.

- Description: The purpose of this investigation was to determine the properties that characterise cotton fibres in the various stages in the CPNF process as well as to determine which fibre characteristics a r e required to entangle the fibres to produce a successful CPNF . The criteria adopted in this work for a successful CPNF include: 1. the tensile strength of the fabrics 2. a well-defined pattern 3. absorbency and wicking The properties selected for investigation were 1. the cotton fibre surface (using SEM and DSC analyses) 2. the degree of degradation of the cotton fibre as a result of the CPNF process (using cellulose fluidity measurements) 3. the non-cellulosic content of the fibre (using IR, DSC, and Chemical analyses) 4. fibre friction 5. absorbency and wicking 6. tensile properties Analysis of the results indicates clearly what the fundamental properties of the cotton fibre must be for a successful cotton CPNF to be manufactured. The conclusions also indicate the necessary properties a man-made fibre must have to produce a successful CPNF.

Economic impact of international labour migration on Lesotho's development, 1986-1998: towards an international labour migration policy for the Southern African region

- Description: The aim of the thesis is to identify the pressures that contributed to the rise in international labour migration in Lesotho, and to investigate how these pressures are impacting upon the modernization process in the country, particularly at a time when employment opportunities are scarce in the southern African region. International labour migration has been used as a development tool throughout history, but especially in the 20th century by developing countries with dual labour markets. Newly independent developing countries with dual labour markets adapted the strategy of import substitution industrialization (lSI), with an emphasis on protecting infant industries and promoting pro-labour policies. In the post-colonial period the international demand for lowskilled workers rose, particularly in the North (developed countries), and in mineral rich countries including the oil exporters and South Africa, and the newly industrialising countries in East Asia. International labour migration to these countries was adapted as an integral development tool by the governments of the lSI countries. Most migrants were low-skilled and temporary workers in the destination countries. Although no multilateral institutional framework existed, usually both the sending and receiving countries adapted unilateral and bilateral migration policies to guarantee the gains from migration. Workers were thus "protected" to varying degrees under such agreements. From the 1970s, the North experienced a slowdown in the growth in demand for unskilled workers. In the 1980s, many lSI countries experienced devastating economic crises that forced them to abandon the lSI policy and adapt the export-led industrialisation (EOI) policy with an emphasis on trade liberalization. The switch from lSI to EOI in developing countries with dual labour markets led to the downsizing of public sector employment, the removal of marketing boards formally used by small-scale agricultural farmers, and the expansion of export processing zones (EPZs). These outcomes resulted in a rise in push internal migration, and international migration from these countries especially to other developing countries. At the same time, since the late 1980s, capital has acquired greatly enhanced mobility at the global level. The adaptation of EOI and the full mobility of capital at the global level altered the institutional structure within which labour migration was governed both nationally, and internationally. At the national level stricter unilateral policies were reinforced by receiving countries for low-skilled labour, while less strict policies applied for skilled labour. These remain in operation in conjunction with the earlier bilateral agreements. At the international level, there remains a lack of policy to regulate international labour migration. Under the current enhanced mobility of capital, international migrants are thus left vulnerable. Lesotho fits this pattern. Faced with a dual economy and an abundance of semi-skilled labour, Lesotho has been a principal supplier of labour to the South Africa's mining industry since its independence. Lesotho's industrial diversification thus mirrors South Africa's industrial diversification. In the lSI phase (1968 - 1987), international labour migration became the most important tool of economic welfare generation in Lesotho. Bilateral agreements were signed in the early 1970s between Lesotho and South Africa to guarantee the gains from migration. Since the late I980s, the mining industry in South Africa began to downsize production and employment. Fewer novice miners from Lesotho were recruited to work in South Africa. The adaptation of the EOI policy in Lesotho in 1987 introduced EPZ industrialization and trade liberalization. Nevertheless, the retrenchment of mine workers from South Africa is occurring at a time when Lesotho is experiencing an employment crisis. The political independence of South Africa in 1994 was accompanied by stricter international migration policies by the new democratic government of South Africa. Most migrant workers in South Africa are thus now faced with a two-door policy (of the earlier bilateral agreements and the amendments to the Aliens Control Act). This system has left migrant workers vulnerable to exploitation by both employers and the law (police) in South Africa. Nevertheless, international migration from Lesotho to South Africa continues to expand, particularly of the new type of migration - semiskilled female workers in the services sector. At the same time, South Africa is also experiencing an employment crisis. The most important policy implications are, firstly, that migration is subject to the same "casualisation" as other work, with the effects made worse by the "statelessness" of migrants, who are most vulnerable to exploitation. Secondly, multilateralism is needed (e.g., SADC) and holistic, multilateral policies are required. It is clear that under the new global division of labour ad hoc policy towards international labour migration is ineffective.

It is clear that under the new global division of labour ad hoc policy towards international labour migration is ineffective.

- Description: Human wildlife conflict is a considerable conservation challenge that threatens many carnivore species worldwide and is a result of complex socio-economic and ecological processes. An understanding of the drivers of conflict is essential for any efforts to achieve coexistence. This study investigated the levels of conflict, livestock management and tolerance amongst the farming communities of the Southern and Western Kalahari in Botswana. A questionnaire survey was completed with 310 farmers throughout the region. The majority of respondents regarded coexisting with carnivores as a challenge, with losses due to depredation perceived as the greatest problem facing farmers. Conflict was widespread throughout the study area, with some spatial variations for certain species. Cattle management levels were low and while smallstock management was better, the use of improved levels of management could reduce current levels of conflict. Tolerance levels were generally low with few respondents seeing the benefits of coexistence with carnivore species. The results indicated that farm type, gender, education level, source of income, livestock numbers, location and land use all have an effect on perceived conflict and tolerance levels and strongly interact with each other. In general cattleposts were characterised by higher proportions of females, lower education levels, more benefits derived from wildlife and veld products and fewer livestock than fenced ranches. They also experienced more conflict, carried out more management and had better tolerance levels. It could be that closer connections to the land and deriving benefits from natural resources resulted in more tolerance and this is certainly worth further investigation. An improvement in the use of effective methods of livestock management, targeted environmental education programs to develop a greater awareness for the conservation value of carnivores and a diversification of livelihoods to include benefits from natural resources have the potential to reduce conflict and improve tolerance in the Kalahari region.

- Description: This research sets out to examine institutional culture and internationalisation in higher education in contemporary South Africa, by analysing the experiences of black foreign academics at Rhodes University. Much has been written on the adaptation processes of foreign students in South African universities (Ayliff and Wang, 2006; Dzansi and Monnapula-Mapesela, 2012; Mudhovozi, 2011). There is also a host of literature on the black South African experience of adaptation and (non) belonging at historically white universities (HWU) (Akoojee and Nkomo, 2007; Cornell and Kessi, 2017; Soudien, 2008). Comparatively less is written on whether there are any unique pressures regarding institutional culture that black foreign African academics face at historically white institutions such as Rhodes University. The black experience may be misrepresented as a homogenous one by much of the literature on higher education transformation (Batsai, 2019). But there are a host of factors that could change your experience of being ‘black’, such as your class, and gender and quite recently there has been a push to further examine the effect that one’s nationality has on their experience of being ‘black’ in the academy (Batsai, 2019). Institutional culture refers to the “behaviours and values that make up the unique psychological and social environment of a certain institution” (Toma et al., 2005). Internationalisation of higher education in the context of Africa, particularly South Africa refers to “the intentional or unintentional process to integrate intercultural, international and global dimensions in higher education” (Draft Policy Framework for the Internationalisation of Higher Education in South Africa, 2017). In analysing the experiences of international African academics, this research is trying to give a voice to an often-overlooked group of individuals. This research is also meant to portray the black experience in South African higher education as an experience that is not homogenous but reliant on a host of unique identity factors such as gender, class and also their nationality.

- Description: The availability of modern commodity multicore processors and multiprocessor computer systems has resulted in the widespread adoption of parallel computers in a variety of environments, ranging from the home to workstation and server environments in particular. Unfortunately, parallel programming is harder and requires more expertise than the traditional sequential programming model. The variety of tools and parallel programming models available to the programmer further complicates the issue. The primary goal of this research was to identify and describe a selection of parallel programming tools and techniques to aid novice parallel programmers in the process of developing efficient parallel C/C++ programs for the Linux platform. This was achieved by highlighting and describing the key concepts and hardware factors that affect parallel programming, providing a brief survey of commonly available software development tools and parallel programming models and libraries, and presenting structured approaches to software performance tuning and parallel programming. Finally, the performance of several parallel programming models and libraries was investigated, along with the programming effort required to implement solutions using the respective models. A quantitative research methodology was applied to the investigation of the performance and programming effort associated with the selected parallel programming models and libraries, which included automatic parallelisation by the compiler, Boost Threads, Cilk Plus, OpenMP, POSIX threads (Pthreads), and Threading Building Blocks (TBB). Additionally, the performance of the GNU C/C++ and Intel C/C++ compilers was examined. The results revealed that the choice of parallel programming model or library is dependent on the type of problem being solved and that there is no overall best choice for all classes of problem. However, the results also indicate that parallel programming models with higher levels of abstraction require less programming effort and provide similar performance compared to explicit threading models. The principle conclusion was that the problem analysis and parallel design are an important factor in the selection of the parallel programming model and tools, but that models with higher levels of abstractions, such as OpenMP and Threading Building Blocks, are favoured.

- Description: This survey investigates learners’ reading preferences in selected Eastern Cape secondary schools where English is taught as a second language. It seeks to understand the reading patterns and interests of Grade 11s, and the role played by parents, teachers, school and public libraries in promoting a love for reading. Focus group interviews and questionnaires were used to gather data over a period of six weeks. All Grade 11 learners from eight Grahamstown secondary schools where English is taught as a second language participated. Data was analysed using Biomedical Data Programme Statistical Software (BMDP). Chi-square (X ²) tests and t-tests for proportions were used specifically to determine significant differences in the groups (i.e. gender effect, schools and language effect). The data suggest that ESL Grade 11s: 1) do have preferred reading material; 2) have preferred authors; 3) have a preferred language they read in; and 4) read for information. Limited access to reading material affects their reading patterns and ability.

- Description: This study explores the impact incentive effects have on the level of effort exerted by professional men and women tennis players. Understanding what impact incentives have on tennis players can allow for greater understanding of the impact incentives have in the workplace and how employees react to different incentive schemes. The study makes use of data from both the ATP and WTA tour of every tournament played during the 2016 season. This includes player statistics, tournament statistics and in-game statistics from the quarter-finals, semi-finals and finals of each tournament in an attempt to account for initial seeding effects. This provides a total of 440 ATP matches and 389 WTA matches for an overall sample size of 829 professional tennis matches. The findings from this study illustrate in the last three rounds of all the tournaments played, for both male and females, money is not considered to be a key motivator for players. The ATP and WTA results suggest that competitors do not alter their effort levels depending on the level of the tournament. This illustrates that players exert similar effort levels regardless of the amount of money or ranking points available. The outcome of the findings supports that of the capability effect of heterogeneity on players’ performance. This means that the outcome of a match is linked more to the abilities of the competitors involved as opposed to the incentives available. Thus, players will adjust their effort levels according to their opponent and not because there are more money or ranking points available. This suggests that both the ATP and WTA should aim to reduce the differences in abilities amongst the players in an attempt to raise the attractiveness of the sport. Overall, the findings from this study illustrate that the capability effect outweighs that of the incentive effect.

- Description: In order to investigate certain anomalies evident in the literature, the performances of three Xhosa groups (rural dwellers, urban dwellers, and undergraduates) of varying degrees of acculturation and a White undergraduate group, each group consisting of 30 subjects, were measured on tests of mode of field approach and susceptibility to the Müller- Lyer and Ponzo illusions. In addition, the effect of the introduction of a mental set, which facilitated the perception of perspective in the Ponzo figure, on susceptibility to the illusion was ascertained. Mode of field approach was measured by a portable version of the Rod-and-Frame Test. Susceptibility to the Müller-Lyer illusion was measured by a conventional movable- slide, subject-adjustable device, while a piece of apparatus which also worked on the movable slide principle and was subject-adjustable was developed to measure susceptibility to the Ponzo illusion. The set to facilitate the perception of perspective in the Ponzo figure was introduced by having subjects match the length of Ponzo contrast lines embodied in a photograph and a line-drawing of a bridge, both of these pictures having strong perspective cues. The subjects were required to perform the tasks in prescribed order. Standardised English or Xhosa instructions were ensured by the use of "programmed" worksheets for each task. Prior to each experimental task, the more unacculturated subjects performed comprehension checks to ensure that they understood the concepts of equal length and verticality. The results of the study suggested that: (i) When groups of differing acculturation levels are tested, there may be a pronounced negative association of field dependence with susceptibility to the Müller-Lyer and Ponzo illusions. In general, the more unacculturated the subject, the more field dependent and the less susceptible to illusions he was. However, there was no evidence which either strongly supported or refuted the relationship between these attributes at the intra-group level. (ii) There is no intra- group association between susceptibility to the Müller-Lyer and to the Ponzo illusions. This would indicate that they are not necessarily generated by similar inference habits or by similar contour properties. (iii) The introduction of a "perspective set" increases susceptibility to the Ponzo illusion only among acculturated subjects, who have well-developed pictorial depth perception skills and who habitually infer depth in inverted - V configurations. (iv) There is a significant association between acculturation and field independence. The unacculturated subjects, presumably because they lack the skills of visual analysis which are engendered by Western culture, were more field dependent than the acculturated subjects. (v) Provided that their degrees of acculturation are more-or-less equivalent, as were those of the two undergraduate groups, there are no differences in mode of field approach or susceptibility to the Müller-Lyer and Ponzo illusion among Xhosa and White subjects. Summary, p. 112.
