The genus Bergeranthus Schwantes comprises ten species ofleaf-succulent Mesembryanthemaceae that are centred in the Albany centre of endemism and restricted to the Eastern Cape Province of South Africa. No taxonomic revision of the genus, or key to the species of Bergeranthus, has been undertaken since its description by Schwantes in 1926. The species concepts are mostly based on single, or at best severaL cultivated plants and are notoriously narrow and in some cases incorrect. Louisa Bolus described five of the ten currently recognized species of Bergeranthus (as well as B. cookii, B.firmus, B. glenensis, B.jamesii, and B. longisepalus) from cultivated plants that she had never seen in the wild. This narrow species concept, compounded by morphological change that occurs in response to environmental factors, presents an assemblage of ill-defmed and poorly known taxa that have been prioritised for taxonomic attention by various authors. Furthermore, the generic delimitation of Bergeranthus with the closely related genera Rhombophyllum and Hereroa is unclear and requires attention before generic revisions are attempted for all three genera. The taxonomic revision presented here is based on a study of 210 wild populations of Bergeranthus as well as cultivated representatives of these and 135 herbarium specimens. A phenetic analysis based on 36 vegetative characters was initially used to delimit taxa. Thereafter sixty-three macro- and micro-morphological characters were critically assessed for the purposes of species delimitation, amendment of existing species descriptions and the description of two new species. Macromorphological characters examined included rootstock, leaf(36), inflorescence, floral (nine), fruit (nine), seed germination and seedling characters. Micro-morphological characters examined included leaf anatomy, leaf epidermal wax layer, anther shape and point of adherence, pollen and seed characters. This revision reduces two species into synonymy and two new species, B. albomarginatus and B. nanus, are described. Existing species descriptions are improved and all species are illustrated. A key to species is provided. The reproductive biology, ecology, phytogeography and distribution data of the genus are discussed towards an improved understanding of the genus. The generic delimitation of Bergeranthus and its closest relatives, Rhombophyllum and Hereroa, are discussed based on an examination of 25 morphological characters and two phenological characters and a provisional key to genera is provided. A phylogenetic analysis of all 10 species of Bergeranthus, both species of Rhombophyllum and a single species of Hereroa (H. granulata) was undertaken to support species and generic delimitation.

Long-term social processes are explored to examine the shaping of environmental education in eastern southern Africa. The study opens with early Nguni social figurations when 'to conserve was to hunt.' It then examines colonial conservation on the frontiers of imperial expansion and developing struggles for and against wildlife preservation. These processes shaped an inversion of earlier harmonies as declining wildlife was protected in island sanctuaries of natural wilderness and 'to conserve was not to hunt.' Inside protected areas, conservation management struggles shaped new harmonies of interdependence in nature, enabling better steering choices in developing conservation science institutions. Here more reality congruent knowledge also revealed escalating risk which was linked to a lack of awareness amongst communities of 'others' outside. Within continuing conservation struggles, education in, about and for the environment emerged as new institutional processes of social control. The study examines wilderness experience, interpretation, extension, conservancies and the development of an environmental education field centre, a teacher education programme and a school curriculum. Naming and clarifying the emergent education game for reshaping the awareness and behaviour of others is examined within a developing figuration of environmental education specialists. Particular attention is given to academic and statutory processes shaping environmental education as a field of objective principles and rational processes within modernist continuities and discontinuities into the 1990's. An environmental education field centre, an earth-love curriculum and research on reserve neighbour interaction are examined as political sociologies developing within a declining power gradient and wide ranging socio-political change. Into the present, a final window on a local case of water pollution examines shifting relational dynamics revealing how environment and development education models of process may have little resonance amidst long-term socio-historical struggles and shifting controls over surroundings, others and self. A concluding review suggests that grounded critical processes engaging somewhat blind control over surroundings may yet reshape self-control and social control amongst others. The trajectories of these clarifying struggles must remain open-ended as sedimented myth and memory is reshaped within ongoing processes of escalating risk and global intermeshing.

South Africa is a nation that was born from a struggle that can be said to have turned racial divisions and discrimination into a diversity of heritages. Thus, contemporary South Africa has become a country recreated in such a way that its people are able to embrace diversity freely. This research study aimed to provide insights into South Africa’s diversity in culture and linguistics that were moulded into a single song, the South African National Anthem. The research study aimed to determine the selected sample’s (Nelson Mandela Metropolitan University Staff and Students) responses to the representation of the South African National Anthem based on two specific performances. The research study aimed to determine how the two online videos affected the perceptions of NMMU Staff and Students of the South African National Anthem and South Africa as a brand. The research study aimed to determine how the two performances of the South African National Anthem under study were received by Staff and Students at NMMU. The study also aimed to highlight the similarities and differences in the sample’s responses, based on this reception. The selected YouTube videos under study are: SA anthem destroyed URL: http://www.youtube.com/watch?v=beg0-kMN3fM Ard Matthews ruins the SA national anthem URL: http://www.youtube.com/watch?v=fu6IG0Wx19w. An electronic questionnaire with both closed and open-ended questions was used to draw a conclusion regarding the selected sample’s perceptions of the South African National Anthem. Following the questionnaire results, a rhetoric analysis of the sample’s questionnaire responses was conducted. This text analysis and interpretation was conducted to gain insight into themes that were labelled based on the questionnaire responses, thus affecting perceptions of the sample and determining whether the South African National Anthem was perceived as a tool for division or unification.

Research asserts that learner performance in South African schools is in a state of crisis. While many more learners’ post-1994 in South Africa have physical access to education, very few have epistemological access. The quality of the education learners receive is polarised along socio economic lines. This crisis has its roots in the legacy of colonialism and apartheid, and as such, there is a need to transform the education system to ensure equal opportunity for all learners, and ultimately economic growth and security for the country. One of the explanations offered for the crisis in learner performance is the poor teacher education system. However, there is a paucity of research in teacher education generally in South Africa, and specifically in relation to pre-service teachers. Furthermore, little attention has been given to how initial teacher education could contribute to the promotion of a social justice agenda with the intention of transforming the South African schooling system. This research seeks to understand how the expectations, scaffolding and assessment of preservice teachers’ teaching practices can be utilised to promote social justice during the Teaching Practice (TP) component of initial teacher education. In answering the research question, I analyse data and literature to identify a set of key valued functionings of quality praxis that preservice teachers ought to be provided the capability to realise, at the level of achieved functioning. This is a qualitative case study located in the interpretive paradigm. The case under study is: quality teaching practices of pre-service teachers. This case is bound by context (initial teacher education in South Africa) and setting (the pre-service teacher in the classroom). Two South African Higher Education Institutions (HEIs) were selected through purposive sampling and their respective Teaching Practice (TP) documentation was analysed. Focus group interviews were conducted with five lecturers involved in TP at one of the HEIs. The theoretical framework of the study used to guide the analysis of the data was underpinned by a social justice perspective on quality education. Given that a social justice perspective does not have analytic tools, I view quality pre-service teachers’ teaching practices as praxis and utilise the capability approach as a mechanism for identification and description of valued functionings and capabilities that contribute to quality praxis. There are four significant findings in my research. Firstly, there is consistency with regards to the valued functionings and capabilities across the TP documentation of the two participating HEIs. In other words, the conceptions of a capable pre-service teacher are similar. Secondly, if social justice goals are to be realised, greater clarity of the valued functionings needs to be evident in the TP documentation. Thirdly, the valued functionings can be categorised into those that are foundational and those that promote a social justice agenda. Finally, in promoting a social justice agenda, there are functionings that ought to be valued by the HEIs that are seemingly not currently valued.

The importance of State-owned entities (SOEs) in a developing State has been argued for centuries. SOEs are perceived as the tool that the State can successfully use to implement its developmental agenda. In the Republic of South Africa, SOEs have been used to ensure universal access to electricity, water and logistical infrastructure to support industrial development, as well as basic service delivery. These entities have been expected to fund these initiatives from their own funds, which alleviated the need for commercial SOEs (also known as State-owned companies) to be profitable without continuous financial injections from the RSA government. Generally, commercial SOEs have been performing poorly financially. This research study aims to determine whether political influence might affect the profitability of these commercial SOEs. The poor financial performance plaguing the commercial SOEs hinders their ability to effectively contribute as a collective to the developmental agenda of the State, as espoused in the current strategic plan of the RSA in the form of the National Development Plan (NDP). Due to the poor financial performance and subsequent diversion of financial resources from other national priorities for their bail-out, commercial SOEs have been considered a liability rather than an asset to the RSA. To satisfy the primary and associated research objectives, qualitative primary and secondary research data have been collected. The primary data have been collected by using the semi-structured interview from the CFOs of commercial SOEs from various government departments – given their proximity to the financial performance and the drivers of this performance in commercial SOEs. CFOs are also part of the commercial SOEs senior-executive management of these entities. The general opinion of the participants and the literature review of the research study is that, indeed, political influence has had an adverse effect on the profitability of commercial SOEs, among others, as a consequence of the positioning of SOEs within the governance system of the RSA, the impact of the recruitment process for senior executives and the implications of an unfunded mandate. It is clear that in the RSA, commercial SOEs, and SOEs in general, will continue to play a pivotal role in the implementation of the developmental agendas of the State, as expressed in the NDP. With the RSA government expecting commercial SOEs to fund these activities from their own funds, it is critical that the State should be an enabler rather than a hindrance for commercial SOEs‟ profitability.

[From the Preface]: A Study in Local History: Grahamstown 1883-1904 aims to draw into a coherent picture the threads of political attitudes, approaches to racial issues and changes confronting the late Victorians in Grahamstown, particularly in the areas of sanitation, public health and shifting commercial frontiers. The relation of local development to national affairs has been investigated, although attempts to define exactly how the former influenced the latter, and vice versa, would involve one in the proverbial chicken-and-egg syndrome. Let it suffice to say that an understanding of events in the microcosm, or locality, lends clarity to the cross-current of affairs at the national level. It begins at the point where Grahamstown's commercial importance in the Eastern Cape declines after a flourish of hopes in the prospects of the Port Alfred harbour as a means of bringing trade back to Grahamstown. The study concludes when the foundation of Rhodes University College in 1904, provides a new centre of development for the city.

A Period of Transition : A History of Grahamstown 1902-1918 attempts to show that the trends begun in the nineteenth century were confirmed by developments in the first two decades of the twentieth century. In this period, Grahamstown was forced to abandon ideas of economic recovery and political importance, as it adapted to its role in the post-Union dispensation. The city has been firmly grounded in the wider environment, though comparison with towns of similar position and outlook has been impossible because of a lack of source material.4 It is clearly evident that Grahamstown was under pressure from the macrocosm; nonetheless, local initiatives and developments also lent clarity to broader trends. This is particularly clear in the emerging pattern of racial segregation in the City, to cope with the economic and social problems posed by a burgeoning black population. The limited financial resources of a corporation the size of Grahamstown restricted its effectiveness to improve schemes of public works and public health, and further underlined the dependence of the city on the government for assistance. Grahamstown's transition was predominantly one of acceptance of a changed political, social and economic environment.

From Introduction: During the past three decades or more, the study of absenteeism in industry has been carried on in many different ways, by numerous investigators and in a wide range of industries. The purpose of such studies has varied; sometimes they have been stimulated by purely academic interest and have sought to investigate the relationship between absenteeism and various other measurable factors in the work situation such as age, race, sex, length of service and wage rates. Most studies, however, have been prompted by the urgent necessity to determine whether an absence problem existed within a specific factory, community or industry and to discover some effective means of dealing with it. Most studies have been empirical and pragmatic as has befitted their intentions. Inevitably, those who have conducted studies of the latter type have asked two questions (a) how do the absence rates emerging from this investigation compare with those from other studies and (b) are they 'normal' or 'abnormal'? In other words, does the data which has been gathered indicate the existence of an absence problem? The main purpose of this monograph is to demonstrate that the Gross Absence Rate is not an effective basis for the discovery of answers to either of these questions. It will seek, in other words, to demonstrate the truth of the following fundamental postulate: THE GROSS ABSENCE RATE IS NOT, IN ITSELF, A SUFFICIENT BASIS FOR THE COMPARISON OF THE ABSENCE BEHAVIOUR OF ONE GROUP OF WORKERS WITH THAT OF ANOTHER OR WITH A PRE-ESTABLISHED NORM, NOR IS IT AN ADEQUATE INDICATOR OF THE PRESENCE OR OTHERWISE OF AN ABSENCE PROBLEM AMONG ANY GIVEN GROUP OF WORKERS. Although this study will include some account of investigations into the relationship between absence rates and various socio-economic factors, it will do so primarily in order to seek support for the above postulate.

South Africa is undergoing fundamental transformation at all levels of government and civil society, requiring a firm commitment to redressing the legacy of apartheid and to the development of South Africa's people. Part of this commitment is to undertake research which complements transformation processes, investigating the most appropriate ways to meet the challenges posed by such change. This study examines the potential of drama in the secondary school to meet key educational challenges, motivating strongly for the inclusion of drama as part of the formal curriculum in all schools. Social transformation has been greatly influenced by policy such as the Reconstruction & Development Programme (RDP) and subsequent Government White Papers which identify the need to develop South Africa's human resources as crucial. It is in this light, arid in the context of great disparity that exists across the education spectrum, that learning experiences of high quality must be provided in schools. It is argued that drama, as an lift form and an educational medium, is able to provide such qualitatively sound learning experiences because it is essentially learner-centered, experiential and holistic, offering unique ways of knowing, understanding and gaining insights. However, the classroom drama experience needs careful conceptualisation itself, particularly in view of the fact that life experiences of pupils are characteriseg by multiplicity and diversity within a new era of social and cultural mixing, as well as increased global interaction through, for example, the mass media and the internet. This study thus argues from a post-structuralist perspective, which embraces notions of multiplicity, proposing a reconceptualisation of the classroom drama experience that challenges the oppositional or binary perspectives that have previously characterised the way we think about drama and education. Example~ include art versus utilitarianism; process versus product; drama versus theatre. Investigating the classroom drama experierice in the light of developments in postmodern theatre, this study proposes that classroom drama should be seen as a form of theatre itself and suggests the term theatricalisaction to describe this classroom-theatre process which is based on action, reflection, experience and creative expression. It becomes a theatre of activity or an activating theatre. In this light classroom drama is considered in a specifically South Mrican context. In particular, this study examines the ways in which the following contexts impact upon the drama experience: the education system, the place of the arts within that system, and cultural and linguistic diversity in the classroom. Drawing on policy documentation, conference proceedings and studies that have been carried out in multiculturalism and multilingualism, the specific educational challenges facing South Africans are identified. In further exploring the potential of drama to meeting these challenges, this study documents the results of surveys conducted with drama teachers and with ~students who have studied drama as one of their formal subjects, highlighting in particular their perceptions, perspectives and experiences regarding the aims and value of drama education. Finally, in light of the information gained from teachers and learners, and of the concepts and contexts investigated, this thesis considers the ways in which the drama experience can contribute to meeting three primary educational challenges: the building of a culture of learning; the development and empowerment of pupils; and the embracing of cultural and linguistic diversity. This study concludes that drama is able to contribute significantly to educational change because of the teaching and learning processes it offers as an art form, and in particular, a theatre form. It is such a participatory, democratic classroom-theatre which provides a teaching and learning approach that should be at the core of transformation.

In a context of declining capture fisheries and public pressure for greater access to marine resources, marine aquaculture is receiving increasing interest from the South African government as a means to increase the diversity of economic activities in coastal regions, thereby providing employment and reducing poverty. The east coast rock lobster Panulirus homarus rubellus is currently harvested by subsistence fisherman along the former Transkei coastline of south-east South Africa and presents a possible opportunity for ongrowing wild juvenile lobsters in culture facilities. Lack of compliance coupled with poor enforcement of the minimum size limit (65 mm carapace length) has resulted in the ongoing harvest of undersize size lobsters by subsistence fishers. Generally, fishers either consume these undersize lobsters or sell them to tourists for low prices. In line with international trends in rock lobster aquaculture, interest has subsequently arisen in the possibilities of ongrowing these undersize lobsters as a means of adding value to the P. h rubellus resource for subsistence fishers. The aim of this physiological study was to assess the biological feasibility of harvesting, transporting and culturing wild caught juvenile lobsters, thereby provide empirical data to inform the development of suitable transport and culture protocols. The experimental objectives were to asses the effect of temperature on growth and survival of P. h. rubellus, as well as the effects of a suite of extrinsic and intrinsic factors on ammonia excretion and oxygen consumption. Juvenile lobsters were collected by hand from near-shore reefs (2-15 m depth) off Mdumbi in the former Transkei, Eastern Cape Province and transported by road (7 hours) to the Port Alfred Marine Research Laboratory where they were held in a recirculating culture system. The effect of temperature over a range of 9.7 °C (18.9±0.7 to 28.6±1.5 °C) on the growth and survival of juvenile P. h. rubellus fed a diet of fresh mussel flesh was investigated. Specific growth rate (SGR) was significantly different between temperatures (p = 0.01), with the highest values recorded for the 24 °C and 28 °C treatments. There was no significant difference in moult increment (MI) between temperatures, however, intermoult period (IMP) differed significantly between temperatures (p = 0.0015) with mean IMP lowest at 24 °C, although not significantly different from the means of the 26 °C and 28 °C treatments. IMP was highest at 19 °C and 21 °C. Apparent feed intake was significantly different between treatments (p < 0.0001) and exhibited a strong positive correlation with increasing temperature. Food conversion ratio (FCR) differed significantly between temperatures (p = 0.02) with 24 °C exhibiting the most efficient FCR. The results for growth rate and food conversion efficiency suggested that 24 °C is optimal for the growout of juvenile P. h. rubellus. In the second study, the effect of body weight, emersion, daily rhythm, feeding and ambient ammonia on the total ammonia nitrogen (TAN) excretion rate was investigated. Body weight (n = 16, range of 16.8 – 322 g) was positively correlated to daytime TAN excretion rate (mg h⁻¹). Re-immersion after one hour emersion in a moist environment was characterized by a significant increase in TAN excretion rate for the first hour compared to pre-immersion levels. The amount of TAN excreted during this period was as expected if basal TAN excretion rates were maintained during emersion. TAN excretion rates returned to pre-emersion levels by the end of the second hour. There was no evidence of a daily rhythm in TAN excretion rate for P. h. rubellus. TAN excretion rates were elevated following feeding. An initial peak in TAN excretion rate after seven hours (7.58 times pre-feeding rate) was followed by a smaller peak after 13 hours (6.69 times pre-feeding rate). TAN excretion rate dropped to levels not significantly different from pre-feeding levels after 23 hours and consistently returned to pre-feeding levels after 42 hours. The TAN excretion rates of lobster exposed for two hours to an ambient TAN concentration of 1.02±0.10 mg l⁻¹ and 2.3± 0.2 mg l⁻¹ were not significantly different from TAN excretion rates recorded at low ambient water TAN prior to exposure. Exposure to an ambient TAN concentration of 4.45±0.78 mg l⁻¹ had a significant effect on the TAN excretion rate, with pronounced ammonia uptake occurring for all animals at this concentration. The third study investigated the effects of body weight, diurnal rhythm, feeding and emersion on lobster oxygen consumption. Body weight was positively correlated to both standard and active oxygen consumption (mg O2 h⁻¹) while body weight was negatively correlated to mass-specific standard oxygen uptake (mg O2 g⁻¹ h⁻¹). Diurnal rhythm exhibited a strong effect on the lobsters oxygen consumption, with average night time values 67% greater than those recorded during the day. This was related to activity driven by intrinsic nocturnal foraging behaviour. Feeding resulted in a classic specific dynamic action (SDA) response, with postprandial oxygen consumption increasing to a peak before decreasing gradually to preprandial levels. Emersion resulted in a significant increase in oxygen consumption, with lobsters rapidly recovering to pre-emersion levels after four hours. Results from these studies suggest that the capture, transport and culture of juvenile P. h. rubellus is biologically feasible. Empirical data generated were used to provide recommendations regarding species optimised transport and culture protocols. A purge time of 48 hours before transport is suggested to ensure that ammonia excretion and oxygen consumption are at basal levels. Furthermore, emersed transport for a period of one hour is characterised by rapid recovery upon re-immersion. In order to prevent the accumulation of stressors, it is suggested that consecutive periods of emersion are interjected with recovery periods (five hours) in water to allow the removal of accumulated ammonia and repayment of the oxygen debt incurred. The recorded ammonia rates indicate that a biological filter size of 4.8 m³ is recommended for 1000 kg of fed lobsters in a culture situation, although this can be reduced considerably if lobsters are being held without feeding (0.72 m³). A flow rate of 112 l kg⁻¹ h⁻¹ is required to meet the metabolic requirements of lobsters. Bottlenecks to the viable commercial culture of P. h. rubellus, and the ability of this practice to provide the socio-economic benefits that were envisioned, are discussed.
