- Description: Although much effort has been placed into the reduction of risks associated with manual materials handling, risk of musculoskeletal disorder development remains high. This may be due to the additional muscle activity necessary for the maintenance of postural equilibrium during work tasks. This research proposes that postural control and subsequent additional muscle activity is influenced by the magnitude of the external load and the degree of body movement. The objective of this research was to identify whether performing tasks with increased external load and with a greater degree of trunk motion places additional strain on the musculoskeletal system in excess of that imposed by task demands. Twenty-four male and twenty-four female subjects performed four load manipulation tasks under three loading conditions (0.8kg, 1.6kg, and 4kg). Each task comprised of a static and dynamic condition. For the static condition, subjects maintained a stipulated posture for ten seconds. The dynamic condition required subjects to move and replace a box once every three seconds, such that a complete lift and lower cycle was performed in six seconds. Throughout task completion, muscle activity of six pairs of trunk muscles were analysed using surface electromyography. This was accompanied by data regarding ground reaction forces obtained through the use of a force platform. After the completion of each condition subjects were required to identify and rate body discomfort. Differential analysis was used to isolate the muscle activity and ground reaction forces attributed to increased external load and increased trunk movement. It was found that the heaviest loading conditions (4kg) resulted in significantly greater (p<0.05) muscle activation in the majority of muscles during all tasks investigated. The trend of muscle activity attributed to load was similar in all significantly altered muscles and activation was greatest in the heaviest loading condition. A degree of movement efficiency occurred in some muscles when manipulating loads of 0.8kg and 1.6kg. At greater loads, this did not occur suggesting that heavier loading conditions result in additional strain on the body in excess of that imposed by task demands. In manipulated data, trend of vertical ground reaction forces increased with increased load in all tasks. Sagittal movement of the centre of pressure attributed to load was significantly affected in manipulated data in the second movement phase of the “hip shoulder” task and the second movement phase of the “hip twist” task. The “hip reach” task was most affected by increased load magnitude as muscle activity attributed to load was significantly different (p<0.05) under increased loading conditions in both movement phases in all muscles. Further, a significant interactional effect (p<0.05) between condition and data point was found in all muscles with the exception of the right and left lumbar erector spinae during the second movement phase of the “hip reach” task. Muscle activity associated with increased trunk motion resulted in additional strain on the trunk muscles in the “hip shoulder” and “hip reach” tasks as muscle activity associated with the static component of each of the above tasks was greater than that of the dynamic tasks. Trend of ground reaction forces attributed to increased trunk motion generally increased under increased loading conditions. Additionally, a significant interactional effect (p<0.05) between load and muscle activity pattern was found in all muscles during all tasks, with the exception of the right rectus abdominis in the first movement phase of the “hip shoulder’ task, the left rectus abdominis in the second movement phase of the “hip knee” task and the right latissimus dorsi during the first movement phase of the “hip twist” task. This was accompanied by a significant interactional effect (p<0.05) between load and sagittal centre of pressure movement attributed to load, in both movement phases of all tasks investigated. From this research it can be proposed that guidelines may underestimate risk and subsequently under predict the strain in tasks performed with greater external loads as well as tasks which require a greater degree of trunk motion. Therefore, this study illustrates the importance of the consideration of the muscle activity necessary to maintain postural equilibrium in overall load analyses.

- Description: Internet Service Providers (ISP’s) are crucial to the operation and development of the Internet. However, through the performance of their basic functions, they faced the great risk of civil and criminal liability for unlawful content posted by third parties. As this risk threatened the potential of the Internet, various jurisdictions opted to promulgate legislation that granted ISP’s safe harbours from liability. The South African (RSA) response is Chapter XI of the Electronic Communications and Transactions Act (ECTA). The protection it provides is however not absolute. It is limited to ISP’s that are members of an Industry Representative Body (IRB) and those ISP’s must perform particular functions in relation to third party content in a certain manner to obtain limited liability. Due to the ECTA’s limited application and a lack of authority, the question is raised as to what is the liability of ISP’s for unlawful content posted by third parties? This dissertation pays particular attention to ISP liability for third party defamatory statements, hate speech, and obscene and indecent material. The role and characteristics of ISP’s in the functioning of the Internet is described. It is determined that a wide legal definition would be required to encompass the many roles they perform. The definition provided by the ECTA is wide and many different types of ISP can fall underneath it. This may have unintended consequences as entities may receive protection that the legislature did not intend. The appropriate laws in the United States of America (USA) and the United Kingdom are surveyed and suggestions as to the extent of ISP liability in circumstances where the ECTA does not apply are made. It is established that their position is uncertain due to difficulties in applying the law to the Internet. This could result in the law being applied incorrectly and ISP’s erroneously found liable. The ECTA’s threshold requirements limit the availability of the safe harbor provisions to ISP’s that are members of a recognised IRB. The IRB must comply with an extensive set of requirements to obtain recognition. The purpose of these requirements is to ensure that only responsible ISP’s obtain the protection provided by the act. After an examination of these requirements, their necessity is questioned as their purpose appears to be contrary to the logic of the safe harbours provided by the ECTA. The safe harbours are analysed and comparisons made to similar legislation that exists in the USA and the European Union (EU). It was established that the ECTA is a hybrid of the USA and EU legislation, and to a certain extent improves on them. It was suggested that the extent of ISP liability in relation to certain unlawful content is clearer under the ECTA. However, exceptions may exist in relation to hate speech and obscene and indecent content as a result of legislation that does not properly take the technology of the Internet into account. It was recommended that certain action be taken to correct this position to prevent any negative effects on the Internet industry and conflict with the objectives of the ECTA. The provision of limited liability contained in the ECTA is balanced with a notice and takedown procedure, which provides relief to victims of unlawful content. This procedure is analysed and it appears to be effective in providing relief. However, through an examination of concerns raised in relation to this type of procedure as it exists in the USA and the EU, it is suggested that certain flaws exist. The take-down procedure negatively effects the freedom of expression and the third party’s rights to due process. Further, the threshold requirements result in not all the users of the Internet being provided with the same remedies. It is recommended that certain action be taken to correct these flaws. The solution provided by the ECTA should be favoured over the uncertainty that existed before it promulgation. It may be necessary to correct particular flaws that exist. Certain recommendations are suggested in this regard and the concluding chapter.

The purpose of the article is to advance the broader research agenda of RCEs through reflection on the empirical research agenda of one RCE, Makana RCE in South Africa. As such it opens questions on how we might see RCE’s as morphogenic social learning processes (i.e., processes of social change). It provides an oversight of the key issues, educational foci and developing areas of engagement in the Makana RCE. These provide an overview of the ‘starting points’ for social learning in the Makana RCE. A model of social learning is also provided which seeks to engage the ecocultural nature of sustainability practices in the Makana RCE.

- Description: The giraffe at Nyaru were found to be browsers who made little use of graze during the study period. They utilized a diversity of 20 browse species. Two species, Acacia karroo and Acacia cyclops, formed the bulk of the giraffe diet throughout the year. A definite seasonal dietary shift was evident. A. karroo was favoured in summer and autumn and formed the main food species in spring, summer and autumn. A. cyclops was favoured throughout the study, but its contribution to the diet increased during winter when less A. karroo was consumed. This seasonal shift is related to the deciduous nature of Acacia karroo. Although a seasonal shift in species contribution to giraffe diet has been observed in many other giraffe feeding studies, no studies on giraffe feeding have been done in the Mosaic Thicket of the southern Cape. The ecological browsing capacity for giraffe in thicket was estimated to be between 0.020 BU/ha and 0.095 BU/ha. The browsing capacity for giraffe at Nyaru, based on the available phytomass 2–5 m above the ground, was estimated using those species that formed the bulk of the giraffe diet, and amounted to 0.063 BU/ha. A maximum of three giraffe could thus be stocked on the 157 ha of suitable giraffe habitat on Nyaru. This stocking rate recommendation lies within the range commonly recommended by local consultants for giraffe introductions into the southern Cape. Their recommendations are, however, not based on quantitative assessments such as performed in this study. The recommendation of this study should not be applied as a fixed ecological capacity for giraffe in thicket, but should be seen as a starting point in the adaptive management cycle. Ongoing monitoring of parameters, such as herbaceous composition and phytomass; as well as the condition of key browse species, is strongly advocated. A. karroo was browsed significantly more and carried significantly fewer pods per tree at a heavily used site compared to a lightly used site. Heavy browsing thus appears to affect the reproductive success of A. karroo significantly. Fewer pods are likely to lead to lower regeneration and thus reduced density of A. karroo. Whether A. karroo will maintain its dominance within the thicket vii community in the long run will be related to how individual plants survive and reproduce and if some can escape from herbivory. Fewer G. occidentalis were clumped with other species at the heavily used site compared to the lightly used site. This could possibly be attributed to the fact that intense browsing pressure at the heavily used site caused protective clumps to be eaten away, thus exposing G. occidentalis to higher ungulate browsing. Previous studies have found that nurse shrubs protect G. occidentalis against ungulate browsing. G. occidentalis was browsed significantly more at the heavily used site compared to the lightly used site. There was a general trend of fewer fruits at the heavily used site compared to the lightly used site, while fruits were absent on G. occidentalis growing alone at the heavily used site. This suggests a negative effect of heavy browsing on plant reproductive success and emphasizes the importance of nurse plants for the successful recruitment and hence long term prevalence of G. occidentalis in Mosaic Thicket.

- Description: Although the occurrence of wars between states has been in decline, the same cannot be said of conflict within states – especially when considering the innumerable ‘Civil Wars’ said to have occurred since the end of the Cold War. In this context the use of the word ‘innumerable’ is qualified more by the variance in how ‘Civil War’ is understood as a concept (leading to different claims as to how many conflicts of this kind may have occurred over a period of time) and less by their large number. Claims regarding the occurrence of ‘Civil War’ suggest this type of conflict to be the dominant form at least since the end of World War Two. This prevalence in the face of a decline in inter-state warfare has afforded greater interest to ‘Civil War’ as a topic of inquiry. The understanding that ‘Civil Wars’ have with time increased in their occurrence and changed in their nature comes under investigation in this thesis and is seen as problematic in that the means by which a phenomenon is measured (i.e. through its nature) must be fixed so as to measure the frequency of that phenomenon.

- Description: Although the occurrence of wars between states has been in decline, the same cannot be said of conflict within states – especially when considering the innumerable ‘Civil Wars’ said to have occurred since the end of the Cold War. In this context the use of the word ‘innumerable’ is qualified more by the variance in how ‘Civil War’ is understood as a concept (leading to different claims as to how many conflicts of this kind may have occurred over a period of time) and less by their large number. Claims regarding the occurrence of ‘Civil War’ suggest this type of conflict to be the dominant form at least since the end of World War Two. This prevalence in the face of a decline in inter-state warfare has afforded greater interest to ‘Civil War’ as a topic of inquiry. The understanding that ‘Civil Wars’ have with time increased in their occurrence and changed in their nature comes under investigation in this thesis and is seen as problematic in that the means by which a phenomenon is measured (i.e. through its nature) must be fixed so as to measure the frequency of that phenomenon. Using Social Constructivism as a theoretical lens of inquiry, sense is made of this understanding and, furthermore, the true meaning behind the claim that ‘Civil War’ has changed is revealed. The empirical evidence that accompanies this theoretical work exists in the American Civil War of 1861–1865 and the debate over the conflict in Iraq following the U.S. invasion in 2003. This debate is used as a means by which to bring the contestation over the notion of ‘Civil War’ to the fore, while a comparison of this conflict with the quintessential American Civil War reveals the migration of the term.

- Description: This study examines the role of academic literacies and academic-writing practices at two diverse South African senior secondary schools and the implications that these practices have for academic-literacy teaching in Higher Education (HE). As student academic writing is central to teaching, learning and assessment in HE, learner academic-writing standards at schools will often impact on academic success in HE. This is a concern for HE as research from South African schooling contexts have found that students from secondary schools are seldom equipped to cope with the demands of HE writing practices. In addition, the introduction of a new curriculum (National Curriculum Statement – NCS) based on the principles of the South African constitution and informed by the Bill of Rights, impacted for the first time on senior secondary schools in 2006, when it was implemented in grade 10, and HE received its first cohort of matriculants with an NCS educational background in 2009. Therefore, this study specifically explores teachers' writing practices within an NCS writing-practice design for grades 11 and 12, and assesses its current implications for academic-writing practices in HE. Critical ethnography was selected as the primary methodology as it is concerned with multiple perspectives and explores local-practice contexts. Therefore, it provides a holistic understanding of the complexity of writing practices by examining the participants' writing-practice perceptions, observing their teaching practices and analysing their written responses or feedback to first and final drafts. The data/study sample consisted of three grades 11 and one grade 12 English Home Language and English First Additional Language teachers as well as selected learners from two secondary schools in the Port Elizabeth district. The data was collected by means of classroom observations, teacher interviews and learner samples of academic writing. Although this study focused on the teaching of academic writing by the four teachers, literacy understandings were also explored by describing what literacy practices subjectively meant to the four teachers by determining the meanings they collectively and individually gave to dominant literacy practices in academic writing, especially feedback practices in text production. A detailed examination of the new NCS requirements suggest that it offers an understanding of knowledge as a social construct, advocates a multiple literacies approach to teaching and learning, and allows for a process approach to cognitively-demanding writing which takes cognisance of the rhetorical, social and cultural dimensions of literacy. Collectively, the ASs in LO3 reflect a process approach to writing, from planning, drafting, feedback, revision to presentation of the final text. It also considers the specific rhetorical dimensions of purpose, audience, and context. Therefore, these NCS writing practices should benefit learners advancing to HE. This study argues that if teachers in secondary schools were to adhere more closely to the NCS's LO3 and its ASs implementation guidelines, learners would be better prepared to cope with HE academic-writing requirements. Instead, the study found that the teachers tended to reduce writing practices to the mastery of discrete sets of technical skills with a focus on surface features of language like spelling and grammar. In addition, the study found that when the teachers' perceptions of the NCS and their own classroom-writing practices were explored, they tended to resist a social-practice approach to academic writing, and, as a result, mostly adapted LO3 of the NCS rather than adopting it as intended by the policy-makers. Similar to other South African studies, this study concludes that teachers remain largely rooted in their autonomous teaching practices favouring traditional methods with which they are familiar over curricula policies which could emancipate learners toward levels of achievement which would better prepare them for both HE and the world of work. In other words, teachers in the sample tend to conserve their traditional methodologies which are predominantly informed by deficit views of learners‟ problems, selectively including new policy requirements which create the impression of compliance, rather than fundamentally altering their approaches pedagogically in the classroom and their academic-writing practices in particular.

- Description: The study examines the nature and extent of child labour in Goromonzi District farms in Zimbabwe. The main objective of the study was to investigate the nature and extent of child labour in Goromonzi District farms. The study reveals high levels of child exploitation and abuse. A qualitative design was chosen and purposive sampling was used. Interviews were used to collect data. The sample consisted of 40 children between 7 and 16 years. Interviews were also conducted with the Coalition Against Child Labour in Zimbabwe (CACLAZ). CACLAZ is an NGO that specializes in the elimination of child labour in Zimbabwe through the provision of education. The study reveals different forms of child labour. These include children working in communal and commercial farms, children working in domestic set up and child prostitution. The study exposes some of the causes and effects of child labour. Poverty, increased cost of education, and cultural practices were some of the causes of child labour. The study also reveals gaps that exist in the LRA. In view of the findings, the study makes recommendation on how to curb child labour and protect the rights of children as enshrined in various international instruments such as the CRC and ILO Conventions.

- Description: This thesis is structured around an exploration of the global phenomenon hip-hop. It considers how its far-reaching effects, as a cultural export from the United States,have influenced cultural production in South Africa. The investigation focuses specifically on the work of two visual artists: Zimbabwean born, Johannesburg-based Kudzanai Chiurai, and Cape Town born, Berlin-based Robin Rhode. The introduction familiarises the reader with the two artists and briefly outlines their histories and methods, as well as giving a short history of the development of hip-hop as a subculture from its beginnings in 1970s New York. The first chapter follows this brief introduction to outline some of the parallels, especially concerning race relations, between 1970s America and post-apartheid contemporary South Africa. This comparison aims to highlight similarities that gave rise to the hip-hop phenomenon and which also place South Africa in a prime position to welcome such influences. The second half of the chapter explores how migration theory and issues of diaspora have not only influenced the development of hip-hop, but have also become points of focus for both artists, who are in fact disporans themselves. The second chapter explores ‘ground level’ concerns of everyday life in the city. Issues of crime,gangsterism, politics and activism are characterised as focal elements of Chiurai’s and Rhode’s artwork and also of hip-hop musical content. Inner city contexts in different parts of the globe are compared through a discussion of the art and music that come out of them. This comparison of the philosophical and conceptual content of the art and music is extended, in Chapter three, into a comparison of methods of production, considering how these influence various readings of the artistic output, whether musical or visual. Ideas of authenticity are discussed and finally the focus shifts to explore how both the conceptual and practical concerns of musicians and artists are being shaped by an increasingly ‘globalized’ world. The conclusion explores the challenges that globalization poses to cultural practitioners and seeks to highlight some of the artists’ methods as examples with which to facilitate the growth of a more inclusive global aesthetic.

- Description: Increasingly, developmental psychology has emphasized that childhood career development should be viewed as holistic and comprise all aspects of a child’s maturation. This would include an emphasis on the career development of children which is considered vital to the complete education of the child (Brown, 2002). Career development refers to the process of developing beliefs, values, skills, aptitudes, interests, personality characteristics and knowledge of work (Zunker, 2006). Research has indicated that early societal factors and personal preferences associated with gender influence the child’s later occupational aspirations (Stockard & McGee, 1990). There are many ways in which individuals learn about gender roles and acquire “gender-appropriate” behaviour during childhood, some of which manifest in the occupational aspirations of children. As children grow up they learn, through reinforcement and modeling, that society has different expectations and standards for the behaviour of males and females. While family and friends are often the most important agents of socialization in young children, television and other popular media have also played a vital role in gender stereotyping, resulting in children forming perceptions regarding which occupations “belong” to which gender (Taylor, Peplau, & Sears, 2006). The present research aims to explore, describe and compare the occupational aspirations and the occupational gender stereotyping of male and female South African and Australian senior primary school learners. The research approach for the study was descriptive and exploratory in nature and was conducted within a quantitative framework. A survey-type questionnaire, the Career Awareness Survey xiii (McMahon & Watson, 2001), was used as the data collection measure as part of a larger international study. The sample comprised of 511 South African and 372 Australian participants from Grades 6 and 7. Responses to the occupational aspirations questions were coded according to Holland’s (1985) interest typology and status level coding for occupations. For descriptive purposes, frequency counts were computed for the coded typology, status level and occupational gender stereotyping data. The z-test and chi-square test for independence were computed in order to test whether gender groups differed in terms of their occupational aspirations and occupational stereotyping. The chi-square test was also used to compare the occupational aspirations and gender stereotyping of South African and Australian senior primary school learners. The results of the present research indicate that male and female South African and Australian female children tend to aspire towards more Investigative and Social type occupations in the high status level category. The Australian male children, however, tend to aspire towards more Social and Realistic type occupations in the high status level category. Across nation and gender, the majority of the children believed that both males and females could perform certain occupations, with senior primary school children tending to limit the range of occupations which they believe to be predominantly suited to either male or female. Cross-national comparative results yielded interesting findings with few significant differences emerging on occupational aspiration typology, status level and the occupational gender stereotyping of occupations. The results of the present research emphasise the need for further cross-national comparative studies on the occupational aspirations and occupational gender stereotyping of senior primary school children.

- Description: In Black Skin, White Masks Frantz Fanon discusses the neurotic condition that typifies the oppressed black subject, their ‘psychoexistential complex’. He argues that this neurotic condition is closely related to another, the ‘psychoexistential complex’ of the white oppressor. Both of these complexes sustain and are sustained by social and economic injustice. But Fanon does not delve in detail into the nature of this second neurosis, for he was primarily interested in discussing this neurosis only insofar as it helps him understand the first. My aim in this paper is to provide an account of the white neurosis, and why it should be understood literally as a neurotic condition. Typical, white oppressors, not solely those who are militantly committed to oppressing others, are alienated from the world and from themselves, making their behaviour seem like that of soulless dolls, to use J.M. Coetzee’s image from Age of Iron.

- Description: Background: The ideal treatment of Attention-Deficit/Hyperactivity Disorder is a highly debated issue. Opposition to pharmacological treatments has resulted in the popular use of non-pharmacological measures which are not necessarily efficacious for the management of ADHD. Objectives: The primary aim was to evaluate the treatment of children and adolescents diagnosed with ADHD in South Africa. Methods: The study consisted of two parts, a drug utilisation review (DUR) and questionnaire-based surveys. The DUR was conducted using a database containing central nervous system (CNS) drug prescriptions which were dispensed during 2008. A total of 21 650 prescriptions dispensed to 7 202 patients constituted the Primary study population which was analysed. The questionnaires were distributed to the parents/caregivers of children diagnosed with ADHD. A response rate of 20.81 percent was obtained. Results: The average age of patients in the DUR was 11.60 ±3.01 years. Male patients represented 74.09 percent (5 336: n = 7 202) of patients. Methylphenidate was the most commonly prescribed of the two drugs indicated for the treatment of ADHD (85.89 percent, 18 956: n = 21 650). A prescribing bias by practitioners in different parts of South Africa was identified. Drug holidays were identified during March and December of 2008. The average age of patients in the questionnaire was 10.67 ±2.83 years, with a male patient majority (86.11 percent, 31: n = 36). Methylphenidate was the most commonly used prescription treatment (93.75 percent, 30: n = 32). Drug holiday use was reported in 56.25 percent (18: n = 32) of patients. Most participants reported supplement use (83.33 percent, 30: n = 36), but 86.67 percent (26: n = 30) of these participants did not find them useful. Conclusion: ADHD is a poorly understood disorder which affects people in all spheres of life. Treatment of the disorder should be individualised and based on scientifically proven effectiveness. Further studies, both in South Africa and worldwide, need to be conducted on the treatment of ADHD

The DUR was conducted using a database containing central nervous system (CNS) drug prescriptions which were dispensed during 2008. A total of 21 650 prescriptions dispensed to 7 202 patients constituted the Primary study population which was analysed. The questionnaires were distributed to the parents/caregivers of children diagnosed with ADHD. A response rate of 20.81 percent was obtained. Results: The average age of patients in the DUR was 11.60 ±3.01 years. Male patients represented 74.09 percent (5 336: n = 7 202) of patients. Methylphenidate was the most commonly prescribed of the two drugs indicated for the treatment of ADHD (85.89 percent, 18 956: n = 21 650). A prescribing bias by practitioners in different parts of South Africa was identified. Drug holidays were identified during March and December of 2008. The average age of patients in the questionnaire was 10.67 ±2.83 years, with a male patient majority (86.11 percent, 31: n = 36). Methylphenidate was the most commonly used prescription treatment (93.75 percent, 30: n = 32). Drug holiday use was reported in 56.25 percent (18: n = 32) of patients. Most participants reported supplement use (83.33 percent, 30: n = 36), but 86.67 percent (26: n = 30) of these participants did not find them useful. Conclusion: ADHD is a poorly understood disorder which affects people in all spheres of life. Treatment of the disorder should be individualised and based on scientifically proven effectiveness. Further studies, both in South Africa and worldwide, need to be conducted on the treatment of ADHD

- Description: The Great Escarpment forms a semi-continuous mountain system 5 000 km long, stretching from Angola in the north-west, south through Namibia, and into western, southern and eastern South Africa, including Lesotho and Swaziland. It is composed of a wide variety of geological suites but is unified in representing the edge of the African plateau and the passive Gondwanan continental margin. The Great Escarpment falls into all major climatic zones on the subcontinent, is a repository of palaeo- and neo-endemics, hosts more than half of southern Africa‟s centres of plant endemism, and has a rich suite of endemic fauna. In addition, the Great Escarpment is believed to be both a refugium and corridor for biological diversity. Despite the biological richness of the Great Escarpment, research to date has been fragmented and many sections of the Great Escarpment have not been studied. The aim of this study is to contribute to research on the Great Escarpment by undertaking a detailed floristic study of the southern Great Escarpment (the Sneeuberg, Nuweveldberge and Roggeveldberge). Together these mountains comprise approximately 1 000 km (one fifth) of the Great Escarpment, and occupy a transition zone between the summer rainfall zone in the east and the winter rainfall zone in the west. They are also the sections of Great Escarpment most closely situated to the Cape Floristic Region (CFR) and would thus be involved in hypothesised migration routes for lineages that also occur further north through the Drakensberg Alpine Centre (DAC) to the East African mountain chain. Detailed fieldwork of the southern Great Escarpment was undertaken over a period of four years in all seasons. Approximately 8 000 specimens were collected. Particular emphasis was placed on areas that may represent refugia, i.e. the highest plateaux and peaks, mesic areas and cliff-lines. An overview of each mountain range, together with their endemic plant species and phytogeography, is provided. Approximately ten new species have been discovered during this study, two of which have been described to date. Numerous endemics only known from their types have also been rediscovered. The Sneeuberg is defined as a new centre of plant endemism on the Great Escarpment (endemism of 2.3%), and the role of the Boschberg and Groot-Bruintjieshoogde (part of the Sneeuberg) as a nexus for floristic migration routes is discussed. The Nuweveldberge is shown to have low endemism despite a floristic tally similar to the Sneeuberg, while the Roggeveldberge are confirmed to be the most endemic-rich section of the southern Great Escarpment. The field data collected was augmented by available data in taxonomic revisions, and floras for the Sneeuberg, Nuweveldberge and Roggeveldberge were compiled. In order to floristically compare the southern Great Escarpment with other sections of the Great Escarpment and the CFR, a database of some 12 000 taxa was created using available floristic data for the CFR, DAC and Great WinterbergAmatolas, together with the data collated for the Sneeuberg, Nuweveldberge and Roggeveldberge. These data were analysed using phenetic methods and Parsimony Analysis of Endemicity (PAE). The results indicate stronger linkages in the east, particularly between the Sneeuberg and Nuweveldberge, and between the Sneeuberg and the Great WinterbergAmatolas. The relationship of the Roggeveldberge with the rest of the southern Great Escarpment remains ambiguous. In order to refine notions of connectivity and migration routes, 19 well-sampled phylogenies were assessed for sister-taxon disjunctions to explore CFRGreat Escarpment connections. Palaeo-connectivity between the CFR and southern Great Escarpment is most strongly supported for the south-eastern (SE) connection, and less so for the north-western (NW) and Matjiesfontein connections. There is support for the current (or recent) use of these three connections from numerous species that occur on both sides of the connections. Results of these analyses indicate that the southern Great Escarpment is a palaeo-corridor, the functioning of which has been broken by the aridification of the Nuweveldberge since the Last Glacial Maximum (LGM). Floristic connectivity is strongest in the east, from the Nuweveldberge to the DAC, and is less so in the west between the Nuweveldberge and the Roggeveldberge a finding attributed to the transition from a reliable winter rainfall regime on the Roggeveldberge to an unpredictable moisture regime on the Nuweveldberge. The mountains of the southern Great Escarpment are thus a series of refugia from a previous moister, cooler climate and are a corridor between the eastern and western components of the Great Escarpment. The SE connection is the primary link between the CFR and the eastern Great Escarpment Afromontane region in southern Africa. The implications of this research are that accurate conservation assessments and Red Data listings for many of the previously poorly-known endemics can now be made, and appropriate conservation measures implemented. Climate change remains the primary threat to these endemics and montane taxa in general, while degradation of wetlands is the primary threat to the water catchment service provided by the southern Great Escarpment. Future detailed research on the Great WinterbergAmatolas and Stormberg and a comprehensive flora of the HantamRoggeveldberge will further enhance our understanding of the floristics of the southern Great Escarpment, and provide the necessary data for comprehensive GIS-based models of proposed climate change scenarios for local, regional and national conservation planning.

- Description: Development aid in most of the developing countries can sometimes compromise the principles of public service broadcasting (PSB). This may be true when reflected against the tension between donor financed programmes in Malawi and the mandate of Television Malawi (TVM). Although the donor intentions are noble, the strings attached to the funding are sometimes retrogressive to the role of PSBs. A case in point is how donors dictate terms on the HIV/Aids communication strategies at TVM. Producers receive money from donors with strings attached on how the money should be used and accounted for. If producers deviate they are sanctioned through withholding funding, shifting schedules and reducing the funding frequency. The donors also dictate who to interview on what subject, how to conduct capacity building. Some scholars have researched much on the impact of commercialisation of the media. This study is a departure from these traditional interferences; it interrogates the interest of philanthropy tendencies by international donors in the three chosen HIV/Aids programmes broadcast by TVM. The study investigates the extent of pressure exerted by donors on the producers of HIV/Aids programmes in Malawi. Thus, the study seeks to illicit specifics in the power relationship between the donor and the producer hence the study employs the political economy of development aid as applied to the public service broadcasting and communication for development. The study employed qualitative research methods and techniques (in-depth interviews, case study and document analysis). The study reveals how donor ideologies dominate the Aids messages-content output of the texts constructed. The study argues that cultural alienation of the Malawian audiences retards efforts of donors in combating HIV infection rate.

- Description: The quality control of geometrical coherences and relations in modern automobile production is done by different stationary and flexible measurement systems and strategies. Furthermore, there currently exists possibilities of inline measurements and offline measurements. This project presents the basic research concerning the possibility of a flexible wireless measurement system in modern automobile production, that is able to combine the advantages of both strategies. An investigation of existing measurement techniques was done in order to find a sensor technology, which enables the wireless measurement process. The research project introduces the current location systems and positioning systems. These techniques are compared by a value benefit analysis to expose a suited technology as basis for the measurement system. As result of the value benefit anlysis, the ultrasonic technique was selected for further investigations. The ultrasonic test setup is used to analyze the accuracy of modern sensors and to verify the possibility of a project related integration. The tests are done in different conditions, in order to compare the laboratory application and the industrial application. During the test measurements different physical influencing variables and disturbances occurred. From this research project, it can be concluded that the laboratory application of the system is possible. However, the industrial application is subject to restrictions.

- Description: This thesis is a study of the presentation of the orphan child in eighteenth and early nineteenth century English literature, and focuses on William Blake's Songs of Innocence and Experience, Charlotte Bronte's Jane Eyre, and Emily Bronte's Wuthering Heights. It is concerned with assessing the extent to which the orphan children in each of the works are liberated from familial and social constraints and structures and to what end. Chapter One examines the major thematic concern of the extent to which the motif of the orphan child represents a wronged innocent, and whether this symbol can also, or alternatively, be presented as a revolutionary force that challenges society's status quo in Blake's Songs of Innocence and Experience. Chapter Two considers the significance of the child "lost" and "found", which forms the explicit subject of six of Blake's Songs of Innocence and Experience and explores the treatment of these conditions, and their differences and consequences for the children concerned. Chapter Three focuses on Charlotte Bronte's depiction of the orphan in Jane Eyre, which presents two models of the orphan child: the protagonist Jane, and Helen Burns. The chapter examines these two models and their responses to orphan-hood in a hostile world where orphans are mistreated by family and society alike. Chapter Four determines whether the orphan constitutes a subversive threat to the family in Emily Bronte's Wuthering Heights and also explores the notion that, although orphan-hood often entails liberation from adult guardians, it also comprises vulnerability and exposure. The thesis concludes by considering the extent to which orphan-hood can involve a form of liberation from the confines of social structures, and what this liberation constitutes for each of the three authors.

The purpose of this study was to investigate whether aspects of the integrated strategies approach to promoting scientific literacy can be successfully employed in a museum context. The approach was used as part of the education programmes at the Port Elizabeth Museum School (Bayworld) and mixed methods were used to gather qualitative and quantitative data on the teachers’ ability to adopt the strategy. Data were also generated on the teachers’ perceptions of teaching and learning, possible activities which supported the approach, and aspects of the strategy which the learners adopted most readily. The findings suggest that active engagement in the process resulted in effective adoption of the strategy by the teachers, improved attitudes towards science learning by both the teachers and children who participated in the process, and improved scientific literacy in both.

- Description: This dissertation analyses the South African Rental Housing Act 50 of 1999 ("the RHA") with the aim of determining whether the RHA sufficiently protects the landlords‘ rights and interests as opposed to those of tenants (which it does indeed safeguard). Due to the current saturation of rental property in South Africa, landlords are no longer in an advantageous a position as before. In fact, the RHA was introduced to redress the imbalance caused by discrimination against tenants. However, times have changed. The researcher submits that the RHA needs to be re-examined in light perception of the landlord as a consumer. Having regard to both common and foreign law, the researcher identified the following four fundamental legal and practical rights on the part of the landlord: the right to freely contract; the right to safeguard financial interests; the right to safeguard proprietary interests; and the right to evict a defaulting tenant. The research reveals that the RHA does not give adequate recognition to these fundamental legal rights, and accordingly does not sufficiently protect the landlord as a consumer. In total nineteen recommendations how the RHA can adequately recognize and protect the landlord‘s interests are made.

- Description: This dissertation analyses the South African Rental Housing Act 50 of 1999 ("the RHA") with the aim of determining whether the RHA sufficiently protects the landlords‘ rights and interests as opposed to those of tenants (which it does indeed safeguard). Due to the current saturation of rental property in South Africa, landlords are no longer in an advantageous a position as before. In fact, the RHA was introduced to redress the imbalance caused by discrimination against tenants. However, times have changed. The researcher submits that the RHA needs to be re-examined in light perception of the landlord as a consumer. Having regard to both common and foreign law, the researcher identified the following four fundamental legal and practical rights on the part of the landlord: the right to freely contract; the right to safeguard financial interests; the right to safeguard proprietary interests; and the right to evict a defaulting tenant. The research reveals that the RHA does not give adequate recognition to these fundamental legal rights, and accordingly does not sufficiently protect the landlord as a consumer. In total nineteen recommendations how the RHA can adequately recognize and protect the landlord‘s interests are made.
