- Description: This thesis examines selected speculative novels by Margaret Atwood, Ursula K. Le Guin, Doris Lessing and Marge Piercy. It argues that a specifiable ecological ethic can be traced in their work – an ethic which is explored by them through the tensions between utopian and dystopian discourses. The first part of the thesis begins by theorising the concept of an ecological ethic of respect for the Other through current ecological philosophies, such as those developed by Val Plumwood. Thereafter, it contextualises the novels within the broader field of science fiction, and speculative fiction in particular, arguing that the shift from a critical utopian to a critical dystopian style evinces their changing treatment of this ecological ethic within their work. The remainder of the thesis is divided into two parts, each providing close readings of chosen novels in the light of this argument. Part Two provides a reading of Le Guin’s early Hainish novels, The Left Hand of Darkness, The Word for World is Forest and The Dispossessed, followed by an examination of Piercy’s Woman on the Edge of Time, Lessing’s The Marriages Between Zones Three, Four and Five, and Atwood’s The Handmaid’s Tale. The third, and final, part of the thesis consists of individual chapters analysing the later speculative novels of each author. Piercy’s He, She and It, Le Guin’s The Telling, and Atwood’s Oryx and Crake are all scrutinised, as are Lessing’s two recent ‘Ifrik’ novels. This thesis shows, then, that speculative fiction is able to realise through fiction many of the ideals of ecological thinkers. Furthermore, the increasing dystopianism of these novels reflects the greater urgency with which the problem of Othering needs to be addressed in the light of the present global ecological crisis.

- Description: A doctoral study was embarked upon with the intentions of addressing cost management problems encountered on Infrastructure Delivery Projects in South Africa. Given that poor cost performance constitute hindrance to the realization of project goals, it is imperative to eliminate it from project delivery. The prevalence of cost overrun in public sector projects is a call to all stakeholders to address cost management issues in the construction industry. The predominance of cost overruns in public sector construction projects in South Africa has been observed. With the decline of the current economic conditions in South Africa, project performance is a great concern that needs attention. In addition, ineffective initiatives to curb the abuse of the procurement processes are directly affecting the outcomes of construction projects, and if these status quo remains, the sector will continue to have a bad image and continued waste of taxpayers’ money will not cease until the public sector remove non-value adding activities in their operations. Study adopted a mixed methods designed that collected both textual and statistical data. Semistructured interviews were undertaken to determine the outcomes of current project management practices in South Africa. In terms of performance of projects, the status quo paints a disconsolate picture. Findings reveal protracted processes, and the use of unqualified and inexperienced contribute to poor performance of public sector projects. Poor performance continues to dominate the construction sector, especially in the public sector. Interviews data were contrasted with evidence from project-related documents. Based on the data, the study produces a vignette of existing cost management frameworks applied to such projects. Encompassing various stages of the project delivery lifecycle, this vignette will enable an identification of the challenges afflicting cost management on projects. Accordingly, this study identified Lean opportunities from existing cost management practices. Such opportunities will enable identification of effective cost management during project delivery. There appears a need for collaborative cost management practices. Lean tools mentioned for improvement include the 5Whys, the big room, target value design, and the integration of design and construction. A collaborative cost management framework was developed through relevant theories to improve the cost management process of public sector projects.

- Description: Despite the increased focus on men in reproductive research, little is known about male involvement in the initial decision/s regarding parenthood (i.e., to become a parent or not) and the subsequent decision-making that may ensue (e.g., choices about timing or spacing of births). In particular, the parenthood decision-making of “White”, heterosexual men from the middle class has been understudied, as indicated in the existing literature. In South Africa, this oversight has been exacerbated by the tendency for researchers to concentrate on “problematic” men, to the exclusion of the “boring, normal case”. I argue that this silence in the literature is a result of the taken for granted nature of parenthood in the “normal” heterosexual life course. In this study, I have turned the spotlight onto the norm of “Whiteness” and heterosexuality by studying those who have previously been overlooked by researchers. I focus on “White” Afrikaans men’s involvement in parenthood decision-making. My aim was to explore how constructions of gender inform male involvement in decision-making, especially within the South African context where social transformation has challenged traditional conceptions of male selfhood giving rise to new and contested masculine identities and new discourses of manhood and fatherhood. In an effort to ensure that women’s voices are not marginalised in the research, as is often the case in studies of men and masculinity, I conducted in-depth, semi-structured interviews about male involvement in decision-making with both “White” Afrikaans women and men. There were 23 participants in total, who all identified as heterosexual and middle-class. The participants were divided into two age cohorts (21 – 30 years and >40 years), which were then differentiated according to gender, reproductive status, and relationship status. Treating the interviews as jointly produced narratives, I analysed them by means of a performativity/performance lens. This dual analytic lens focuses on how particular narrative performances are simultaneously shaped by the interview setting and the broader discursive context. The lens was fashioned by synthesising Butler’s theory of performativity with Taylor’s narrative-discursive method. This synthesis (1) allows for Butler’s notion of “performativity” to be supplemented with that of “performance”; (2) provides a concrete analytical strategy in the form of positioning analysis; and (3) draws attention to both the micro politics of the interview conversation and the operation of power on the macro level, including the possibility of making “gender trouble”. The findings of the study suggest that the participants experienced difficulty narrating about male involvement in parenthood decision-making, owing to the taken for granted nature of parenthood for heterosexual adults. This was evident in participants’ sidelining of issues of “deciding” and “planning” and their alternate construal of childbearing as a non-choice, which, significantly served to bolster hetero-patriarchal norms. A central rhetorical tool for accomplishing these purposes was found in the construction of the “sacralised” child. In discursively manoeuvring around the central problematic, the participants ultimately produced a “silence” in the data that repeats the one in the research literature.

- Description: This thesis argues that a prominent concern among contemporary writers of fiction is the recuperation of lost or occluded histories. Increasingly, contemporary writers, especially postcolonial writers, are using the medium of fiction to explore those areas of political and cultural history that have been written over or unwritten by the dominant narrative of “official” History. The act of excavating these past histories is simultaneously both traumatic and liberating – which is not to suggest that liberation itself is without pain and trauma. The retelling of traumatic pasts can lead, as is portrayed in The God of Small Things (1997), to further trauma and pain. Postcolonial writers (and much of the world today can be construed as postcolonial in one way or another) are seeking to bring to the fore stories of the past which break down the rigid binaries upon which colonialism built its various empires, literal and ideological. Such writing has in a sense been enabled by the collapse, in postcolonial and postmodernist discourse, of the Grand Narrative of History, and its fragmentation into a plurality of competing discourses and histories. The associated collapse of the boundary between history and fiction is recognized in the useful generic marker “historiographic metafiction,” coined by Linda Hutcheon. The texts examined in this study are all variants of this emerging contemporary genre. What they also have in common is a concern with the consequences of exile or diaspora. This study thus explores some of the representations of how the exilic experience impinges on the development of identity in the postcolonial world. The identities of “displaced” people must undergo constant change in order to adjust to the new spaces into which they move, both literal and metaphorical, and yet critical to this adjustment is the cultural continuity provided by psychologically satisfying stories about the past. The study shows that what the chosen texts share at bottom is their mutual need to retell the lost pasts of their characters, the trauma that such retelling evokes and the new histories to which they give birth. These texts generate new histories which subvert, enrich, and pre-empt formal closure for the narratives of history which determine the identities of nations.

- Description: In hierdie tesis word 'n nuwe benadering tot klasmusiekonderwys in die R.S.A. bespreek. Die navorsing vervat in die tesis is vanaf 1984 tot 1992 gedoen. In 'n sekere sin verklaar die aanvangsdatum van die navorsing die feit dat die projek veral gerig is op die blanke onderwyssituasie aangesien die verskillende groepe se onderwysbelange volgens amptelike beleid grotendeels deur verskillende onderwysowerhede behartig is. Die blanke onderwysgerigtheid van die navorsingsontwerp ten spyt, is die uitgangspunte en die bevindings van die studie, veral ten opsigte van die rol en funksie van musiekopvoeding, sonder twyfel van toepassing op al die Suid-Afrikaanse gemeenskappe. In die opsig behoort die bevindings van die studie dus tot 'n groot mate ook die eise van musiekopvoeding veral vir 'n toekomsgerigte onderwys te kan ondervang juis omdat die vertrekpunt van die voorgestelde vemuwings en aanpassings in die musiekopvoeding die waardes en norme van gemeenskappe moet identiflseer en vertolk en terselfdertyd die beperkende effek daarvan moet teenwerk deur kulturele transenderings. Veral laasgenoemde is van groot belang in die multikulturele opset van die Suid-Afrikaanse gemeenskap waarin die musiekopvoeding juis 'n belangrike rol kan speel in die ontwikkeling van 'n onderlinge begrip en waardering tussen die verskillende kultuurgemeenskappe. In Afdeling A van die tesis word die huidige stand van klasmusiek bespreek en daar word op gewys dat, afgesien van 'n aantal sekondere faktore, die prirnere redes vir die nie-geslaagdheid van die vak, faktore soos die sillabusse, die opleiding van die onderwyser en die posisie van die vak in die kurrikulum is. Teenoor die huidige benadering van klasmusiek met al sy probleme word 'n ander benadering tot die onderwys in die a!gemeen en die klasmusiek in die besonder gestel, naamlik die interdissiplinere benadering met sy twee afdelings, naamlik die geesteswetenskappe en die kunstebenadering. Hierdie benaderings word bespreek soos wat dit in die V.SA. en Europa toegepas word, en daarna word 'n aangepaste benadering vir die R.S.A. ontwikkel ten opsigte van doelstellings,uitgangspunte, riglyne, metodiek en tegniek. In Afdeling B volg die empiriese navorsing wat ten opsigte van die interdissiplinere benadering in die R.S.A. gedoen is, en drie lesreekse, soos beplan vir Standerd 6 en 7; Standerd 8 en vir Standerd 9 en 10 word bespreek. As deel van elke lesreeks word die wordingstand van elke ouderdomsgroep bespreek en in gedagte gehou by die saamstel van hierdie lesreekse. Elke lesreeks bestaan uit 3-4 volledig uitgewerkte lesse wat insluit: hulpmiddels (kunsvoorbeelde, musiekvoorbeelde, gedigvoorbeelde ensomeer), beknopte aantekeninge vir die onderwyser, 'n bronnelys en 'n klankkasset met die nodige klankillustrasies soos waarna in die lesse verwys word. In Afdeling C word die resultate van 'n steekproef bespreek wat gedoen is in verskeie skole in die vier provinsies van die R.S.A. Met hierdie steekproef is beoog om die reaksies van leerlinge en onderwysers te toets ten opsigte van hierdie nuwe voorgestelde, en aangepaste interdissiplinêre benadering. Die lesreekse wat deel vorm van Afdeling B is as basis deur die onderwysers gebruik, maar hul was vry om eie idees te ontwikkel en te gebruik. Die reaksies van die leerlinge en die onderwysers word in die vorm van tabelle en besprekiogs aangedui, en aanbevelings van die leerlinge en die onderwysers word aangetoon. Die tesis word afgesluit met addendums tot die verskillende hoofstukke asook volledige bibliografiese besonderhede.

- Description: In this study I focus on a number of collections of short fiction by the South African writers Joël Matlou, Sindiwe Magona, Zoë Wicomb and Ivan Vladislavić, all of which evince certain of the characteristics of short story cycles or sequences. In other words, they display what Forrest L. Ingram describes as “a double tendency of asserting the individuality of [their] components on the one hand and of highlighting, on the other, the bonds of unity which make the many into a single whole”. The cycle form, thus defined, is characterised by a paradoxical yet productive and frequently unresolved tension between “the individuality of each of the stories and the necessities of the larger unit”, between “the one and the many”, and between cohesion and fragmentation. It is this “dynamic structure of connection and disconnection” which singularly equips the genre to represent the interrelationship of singular and collective identities, or the “coherent multiplicity of community”. Ingram, for example, asserts that “Numerous and varied connective strands draw the co-protagonists of any story cycle into a single community. … However this community may be achieved, it usually can be said to constitute the central character of a cycle”. Not unsurprisingly, then, in its dominant manifestations over much of the twentieth century the short story cycle demonstrated a marked inclination towards regionalism and the depiction of localised enclaves, and this tendency towards “place-based short story cycles” in which topographical unity is a conspicuous feature was as pronounced in South Africa as elsewhere. However, the specific collections which are my concern here increasingly employ innovative and self-reflexive narrative strategies that unsettle generic expectations and interrogate the notions of regionalism and community conventionally associated with the short story cycle. My investigation seeks to explain this shift in emphasis, and its particular significance within the South African context.

- Description: The central argument of this inter-disciplinary study is that IsiXhosa written poetry of 1912 – 2012 is a terrain of the struggle between the contending dominant ideologies of Segregation, Apartheid and Charterism (post-Apartheid); and the subordinate/ subaltern ideologies of Africanism, Charterism (pre-democracy), Pan- Africanism, Black Consciousness Movement and other post Apartheid ideologies. The study highlights the mutual relationship between the text and the context by focussing on the ideological contest which manifests itself in both form and structure (i.e. aesthetic ideology) and the content (i.e. authorial ideology) of the poetry of different epochs between 1912 and 2012. The study is located within the framework of Antonio Gramsci’s theory of cultural construction. Gramsci postulates that ideology and culture play a significant role in the process of asserting hegemony. Important concepts that constitute Gramsci’s theory of praxis are: ideology, culture, hegemony, organic intellectuals and both ideological and repressive state apparatuses. The first chapter presents the problem, the objectives, the methodology, and the scope of the study. The second chapter presents Gramsci’s theory of cultural construction and the work of scholars who developed his theory further. The tool that is employed for analysis and interpretation of textual significations of IsiXhosa written poetry is the revolutionary aesthetics, which is proposed by Udenta. The third chapter analyses and interprets literature of the epoch of 1912-1934 and exposes the contest between Segregation and Africanism ideologies. The fourth chapter contextualises and analyses the literature of 1934 – 1948, the second phase of contestation between Segregation and Africanism. The fifth chapter deals with literature of the first and second halves of the Apartheid epoch (1948 - 1973). The Apartheid ideology contested with the Africanist ideology which transformed into the Charterism ideology in 1955. In 1960 Pan-Africanism ideology and in 1969 Black Consciousness Movement ideologies entered the contest. The sixth chapter examines literature of the period 1973 – 1994 which is the second phase of the Apartheid epoch that ends with the “glasnost” period of 1990 - 1994. The seventh chapter studies literature of the democracy period of 1994 – 2012. The eighth chapter is the summary and general conclusion. The illumination of the nexus between culture and ideology during the past century (1912 - 2012) will provide insights that will assist us in addressing the challenges we face during the democracy period, and in the development on Arts and Culture in general, and literature in particular

- Description: Due to wetland inaccessibility and limited wetland geomorphological studies, there is limited information on the geomorphological origin and hydrological functioning of different types of wetlands in Africa’s elevated drylands. As a result, there is limited information for the development of a comprehensive wetland classification system that classifies wetlands based on long-term geomorphic processes that determine their formation and shape, their structure and hydrological functioning. Therefore, the current study was designed to classify large wetlands in Africa’s elevated drylands based on processes that determine their formation, and shape their structure and hydrological functioning using remote sensing and Geographic Information System (GIS) techniques. Although wetlands perform a number of hydrological functions including groundwater recharge and water purification, the current study focuses mainly on their flood attenuation function. Detailed analysis of topographic information was undertaken using Shuttle Radar Topographic Mission (SRTM) elevations measured at the scale of 30 m x 30 m. LandsatLook and Google Earth images, tectonic as well as geological data were used as supplementary data for developing an understanding of the origin, structure and hydrological characteristics of wetlands. The Principal Component Analysis (PCA) of wetland environmental variables was used to identify and explain wetland heterogeneity. The results of the study showed that fluvial processes, tectonic history and the evolution of Africa’s landscape played a fundamental role in the formation and evolution of wetlands. This study demonstrates a wide range of processes that contribute to wetland formation, structure and functioning. At one extreme it is clear that tectonic processes may be primarily responsible for the creation of basins that host wetlands. At another extreme, wetlands may be structured primarily by fluvial processes. At a third extreme are wetlands that superficially appear to be structured by fluvial processes, but which have their structures modified by gradual rising of the base level at their distal ends, either through marginal uplift adjacent to rift valleys, or through aggradation of a floodplain that blocks a tributary valley. Overall, the classification of wetlands considered in this study can be summarised into four distinct groupings, with two of these divided further into two groupings each: (1) Tectonic basins with little or no indication of fluvial development (Bahi and Wembere wetlands), (2) Tectonic basins evolving towards a wetland with a structure increasingly shaped by fluvial characteristics (Usangu wetland), (3) Fluvially modified valleys with a local base level at the toe of the wetland such as a resistant lithology or a tectonic control that limits the rate of incision of easily weathered and eroded lithologies, leading to valley widening and longitudinal slope reduction, which are of two distinct types: (a) With a catchment on Kalahari Group sediment that is transported fluvially as bedload, and therefore with no prominent alluvial ridge or backwater depressions (Upper Zambezi and Barotse wetlands), (b) With a catchment that produces abundant fine sediment that is deposited as overbank sediments, leading to channel migration via meandering and to the construction of an elevated alluvial ridge (Lufira wetland), (4) Fluvially modified basins with evidence of gradual elevation of the base level at the toe of the wetland, which are of two types: (a) Tectonic marginal rift valley uplift such that they behave more as depression wetlands rather than as wetlands shaped by fluvial processes (Kafue and Luapula wetlands), (b) Tributary valley wetlands blocked by aggradation of the trunk valley (Lukanga wetland). In conclusion, although few geomorphological studies have been conducted on southern African wetlands because of their inaccessibility, Africa’s surface topography and its historical evolution, as well as aridity, provide an opportunity for illustrating the important role that the long-term tectonic, geological and geomorphological processes play in determining wetland origin, structure and dynamics. GIS methodology and Earth Observation (EO) data on the other hand, provide a practical means for acquiring information on inaccessible and hard to traverse wetland systems. A novel cut-and-fill approach for delineating wetlands from a Digital Elevation Model (DEM) was presented as another way in which GIS methodology and Earth Observation (EO) data can provide practical means for assessing inaccessible and hard to traverse wetland systems.

- Description: This thesis sought to explore how community volunteers could be recruited, supported and sustained to assist a community school operating in difficult socioeconomic conditions in achieving basic school functionality. Through a collaborative process, the participants in the study attempted to address a significant gap in the literature, namely how this could be achieved in a way that would be beneficial both to the community volunteers and to the school itself. Based on existing literature, the vast majority of South African schools are struggling to reach the basic functionality levels required in terms of legislation. My interest in this topic was piqued while serving as principal of one such school; hence the focus in this thesis on whether schools would benefit in terms of achieving functionality if they partnered with the communities in which they are located. However, communities are seldom actively involved in the schools and school activities on an ongoing daily basis. In this thesis, I argue for an opportunity for schools and the community to collaborate in a way that would be mutually beneficial. In this, I was guided by the School-Based Complementary Learning Framework (SBCLF) in gaining a greater understanding of how multiple stakeholders could support a school to obtain basic functionality. A key stakeholder is the community in which a school is located, and the multidimensional framework provided a framework to understand why the community would want to get involved in the school. Following a Participatory Action Learning and Action Research (PALAR) design, I recruited 15 community volunteers from the existing pool at my then school; some of whom had been volunteering for over twelve years. We formed an action learning set where we collaboratively sought to understand the processes and conditions needed to recruit, support and sustain community volunteers and their involvement in the school. From this action learning set emerged a key advisors’ set, comprising five members of the action learning set, who were entrusted with the responsibility of planning, preparing and analysing the action learning set meetings. Transcripts and visual artefacts from the action learning set meetings and a focus group meeting of the school management team were analysed to generate data, complemented by secondary sources, such as documents. This participatory approach to data generation allowed the voice of every participant to be heard; agency was increased through active participation; and the sense of affiliation to the group was deepened. The iterative design of the research process further ensured that the participants also engaged in a critical discourse analysis of the emerging data, of which the trustworthiness was enhanced through the use of dialogic and process, catalytic, rhetoric, democratic and outcome validity. The emergence of the data through this collaborative engagement was underpinned by the ethical values of mutual respect; equality and inclusion; democratic participation; active learning; making a difference; collective action; and personal integrity. The findings revealed that community volunteers did add immense value to the school by supporting teaching and learning processes. However, the community volunteers also harboured expectations of material support and opportunities to develop skills. In addition, the study revealed that the hierarchical culture and structures present in most South African schools need to become more democratic and collaborative, with those working to make the school more functional, including community volunteers, being valued, acknowledged and supported. The participants also constructed their understanding of what a community school should be and do and how it should serve the interests of the children from the community. A process model was constructed from these findings regarding on ways to recruit, sustain and support community volunteers involved in community schools, specially designed so that schools could adapt it to suit individual contexts. This study is unique; I am not aware of any similar study ever having been conducted in a community school in South Africa. Furthermore, the collaborative approach used in the study helped ensure that the methodology used could be of value to principals and other school stakeholders in addressing the various complex challenges that confront schools in these contexts. Also, the findings will add to the theoretical body of knowledge around volunteerism, especially in difficult socioeconomic conditions.

- Description: The House Sparrow Passer domesticus, an introduced species, and the Grey-headed Sparrow Passer griseus, an indigenous species, are sympatric in Malawi. Their distribution in the country and any possible interactions were studied, principally in southern Malawi. A morphological analysis of museum specimens confirmed that grey-headed sparrows in Malawi belong to the Northern Grey-headed Sparrow Passer griseus as distinct from the Southern Grey-headed Sparrow Passer diffusus. This species was widely distributed in the, country in association with human dwellings, both in rural areas as well as urban centres. In the northern region Greyheaded Sparrows were more abundant in the urban centres than rural areas, but in the central and southern regions numbers in the rural and urban areas were more or less the same. In Blantyre City, where they are in sympatry with the House Sparrow, they were found in the low density and industrial areas and were absent from the high density areas. The House Sparrow, arrived in Malawi in 1967 at Chileka in the southern region. Since then it has spread northwards, moving from the southern to the central and northern regions. House Sparrow numbers were found to be progressively larger in the southern region and lowest in the northern region. House Sparrows were found at sites where food was readily available, as in the immediate vicinity of houses. In the central and northern regions they were restricted mainly to urban areas. In the southern region, they occur both in rural and urban areas, probably as a reflection of the larger period of colonization in the south. In the northern region their movement has apparently been restricted by geographical barriers. In Blantyre City Grey-headed Sparrows preferred areas where tree density was high and house density was low, while House Sparrows preferred areas where house density was high and tree density was low. There was a positive correlation between Greyheaded Sparrow numbers and tree density and a negative correlation with house density. House Sparrow abundance was negatively correlated with tree density and positively correlated with house density. Grey-headed Sparrows bred in the rainy season, whereas House Sparrows bred throughout the year. There were differences in nest site selection: Grey-headed Sparrows used artificial structures such as fencing poles, and wooden telephone or electricity poles. The House Sparrow used mostly buildings and nested in crevices, holes in walls and between the walls and rafters. Nest height also differed- Grey-headed Sparrows nested at heights ranging from 1 - 8 m while House Sparrow nests were at heights of 1 - 5 m. Moult data suggests that although the House Sparrows breed throughout the year, they moult at a particular time of the year when breeding is less common. Grey-headed Sparrows were found to moult mainly from May to September in southern Africa and from June to September in central Africa. In both cases the breeding season extends over a similar period from about October to April/May of the following year. Peak moult periods differed between the House Sparrows and Grey-headed Sparrows. House Sparrows moulted mainly in the first half of the year, and Greyheaded Sparrows in the second six months. The clutch sizes of the two species were similar (mean 3.9 eggs for the House Sparrow and 3.4 for the Grey-headed Sparrow). The clutch size of the House Sparrow varied seasonally and was larger from November to May. The average incubation period for the House Sparrow was 11.5 days and the fledging period 15.4 days. The Grey-headed Sparrow fledging period was 14.7 days. Chick mortality of the House Sparrow at Chikunda farm was attributed to starvation resulting from brood reduction, abandonment, predation, low birth weight, accidental deaths and parasitism by fly larvae. Both Grey-headed and House Sparrows fed their young on insect food. Male House Sparrows fed actively initially, but their contribution declined from about day five onwards. In the Grey-headed Sparrow, both parents fed their young equally throughout the nestling period. House Sparrows fed on the ground near houses; Grey-headed Sparrows fed both on the ground away from houses and in tree canopies. The Grey-headed Sparrow walked as it fed on the ground as opposed to the House sparrow which hopped. Grey-headed Sparrows fed mainly as pairs and singletons while House Sparrows fed as family groups. Larger feeding groups of Grey-headed Sparrows were seen in the northern region at areas where food was plentiful. Where the two sparrows were seen feeding together, there was no direct competition for food. Where individual distance was violated; male House Sparrows displaced Grey-headed Sparrows which landed too close to them. Overall it appears that the distribution of the two species is determined more by their responses to habitat conditions than by interspecific interactions.

- Description: This thesis explores the biology, ecology, and life-history styles of two closely-related redfin minnows, Pseudobarbus afer and P. asper (pisces; Cyprinidae), which both occur in the Gamtoos River system of South Africa. Five of the seven species of flexible-rayed redfin minnows are in the South African Red Data Book - Fishes. This investigation was designed to provide the data which would enable conservation authorities to manage the remaining populations of the Pseudobarbus species. A thorough understanding of the Gamtoos River system was necessary to properly interpret the findings of this study. The palaeo river systems and the changing climates since the break-up of Gondwanaland are discussed so that the present day environments could be considered as well as the past environmental changes. P. afer and P. asper occur in the Gamtoos River system with no physical barrier separating the two species. P. afer only occurs in the clear mountain streams of the Cape Fold Mountain Belt whereas P. asper occurs in the highly saline and turbid Karoo section of the system. P. afer were found to be the more precocial form of the sister species. They had bigger eggs, lower relative fecundity, shorter breeding season, lower gonadosomatic indices, larger first feeding larval fish, matured later and had a longer life-span than did P. asper, which had more altricial life-history attributes. They differ in their tradeoffs with P. asper devoting more resources earlier to reproduction and having a shorter lifespan. The improvement in the one aspect of fitness (early maturity) leads to the deterioration in another, namely lifespan. Both species undertake breeding migrations to riffle areas where they spawn in mid-channel immediately above a pool after an increase in water flow. P. afer and P. asper are non-guarders of their non-adhesive eggs and young, open substrate spawners on coarse substrates (rocks) and have photophobic free embryos. The breeding season is shorter for P. afer whereas P. asper can spawn as late as April and impoundment releases can induce them to spawn. A study of comparative neuroecology revealed that of the four groups of fish analyzed (males and females of both species) male P. afer had the largest brains, especially the optic lobes and cerebellum. P. asper females had the smallest brains. No neural compensation in the external gustatory centre, the facial lobe, was found for P. asper inhabiting the turbid waters. P. afer also had significantly larger eyes and longer barbels. P. afer males were also found to have the highest density and largest nuptial tubercles as well as the most pronounced breeding colouration. It was concluded that P. asper is the more derived of the sister species pair with regard to life-history attributes. It is further suggested that investment per offspring is important in determining the life-history trajectories. Paedomorphosis has occurred and by this mechanism variability has been restored to the redfin minnows in the Groot River which enables them to survive in the highly variable, intermittent Karoo stream. The more precocial P. afer do not require this variability in the more constant and predictable environment of the Wit River.

- Description: Anyone who has travelled the dusty road in the bed of the Kuruman River from Kuruman in the Northern Cape to the South West African border at Rietfontein cannot fail to have been impressed by the large communal nests of the sociable weaver Philetairus socius which adorn many of the camelthorn trees along the way. One of the earliest reports of the bird and its nest is that of Sir Andrew Smith (1849) who passed that way through what was then Latakoo (the present day Kuruman), collecting birds which he described for the first time. To him we are indebted for the first published illustrations of the sociable weaver, its nest and egg, and a brief account, not entirely accurate to be sure, of the building and occupation of the nest. This account has since been quoted at length by Shelley (1905) and by Friedmann (1930a) who accepted Smith's statements as they stood. Some years after Smith's travels, Anderson wrote (1872) that the flocks of sociable weavers " ... incubate their eggs under the same roof, which is composed by these birds of whole cartloads of grass piled on a branch of some kamel-thorn tree in one enormous mass of an irregular umbrella-shape, looking like a miniature haystack, and almost solid, but with the under surface, which is nearly flat, honeycombed all over with little cavities, which serve not only as places for incubation but also as a refuge against rain and wind". This account gives some idea of the spectacular nests built by these birds which are hardly larger than a sparrow. But, living in the dry and thinly-populated western regions of southern Africa, the sociable weaver remained a remote curiosity, the subject of casual reports and some strange ideas. Since Friedmann (1930a) studied the sociable weaver briefly in the western Transvaal, the only thorough field observations (mainly on nests and nest sites) up to the present have been those of Rudebeck (1953, 1956). Collias & Collias (1964) returned to the western Transvaal some 20 years after Friedmann's visit, but unfortunately had time for only a cursory study; their main interest was once again in the nest and its architecture. Thus, in 1964 when I joined Dr. T.J. Cade, then of Syracuse University and now of Cornell University, on his desert biology programme, he suggested that the sociable weaver be the subject of special study in the Kalahari. Here was a bird, resident in a harsh environment, living throughout the year in an extraordinary nest, and almost completely unknown biologically. Among the questions to be answered were: How is the nest started and how is it constructed? Which birds build, and how is the labour organized? What is the purpose of the elaborate nest: does it provide a micro-climate which enables the birds to survive better under arid conditions? How could such a communal nest have evolved? What is the social organization of the colony in and out of the breeding season? When do the birds breed and what factors induce breeding? What happens to the young birds after they become independent of their parents? Naturally many other questions arose as the work proceeded, but these were the main ones on which the project was initiated.

- Description: To the AmaZulu a warthog is "inhlovudawana" or "little elephant"; to arrogant hunters it is the "poor man's rhinoceros"; to some writers of encyclopaediae it is a "grotesque and hideous beast"; to stockmen it has long been a carrier of diseases. Injury was added to insult with the discovery that the blood of these self-assured, often comical and certainly engaging animals supports the greater proportion of tsetse flies in the African savannas. Their significance as the primary hosts of Glossina morsitans Westw., the vectors of tryanosomiasis, justified an extended field study of warthog biology. This thesis reports four years of field work on warthogs, together with complementary observations of hand-reared warthogs (and their offspring) which roamed freely in the vicinity of the remote field station on which I live. The Sengwa Research Project, of which this study forms a part, was initiated in 1965 to study relationships between game animals and tsetse flies. One of the main problems investigated in the Sengwa Project is that of "host encounter" (Glasgow, 1961, Bursell, 1970) and how the distribution, abundance and behaviour of game animals may affect their availability to hungry tsetse flies. I have, accordingly, been concerned with discovering how warthog are dispersed in the Sengwa area and have attempted to gain some understanding of the factors, both environmental and social, which may affect or govern their dispersion and possibly population number.

- Description: This study was prompted by the need to remedy the situation that existed with respect to the poor status of our knowledge regarding the ichthyoplankton assemblage of the nearshore region along the south-east Cape coast of South Africa. The first chapter provides a brief introduction to the field of ichthyoplankton research and includes a summary of the status of research in southern Africa and an explanation of early life history terminology. The selection of all sample sites, times and strategies is also outlined. The study area along the south-east Cape coast with respect to its location, climate and physical oceanography is described in the second chapter, as is the gear used, bongo nets and an RMT1x6. A sampling protocol for the use of bongos from a small ski-boat, and the RMT from the research vessels, and for the handling and processing of samples was established. The selection of Middlebank as the main monthly sampling site within the Tsitsikamma National Park (TNP) was based on taxonomic diversity as well as logistical and safety constraints. The effect of mesh size and time of sampling with bongo nets on the catchability of ichthyoplankton was investigated in chapter three. Most data was accumulated during Sea Fisheries research cruises, with additional collections coming from the National Parks vessel. Although the differences were not significant, the 505 μ mesh nets captured larger larvae, with catches comprising higher percentages of flexion and postflexion larvae. Larval concentration and size were consistently greater in samples from periods of reduced light intensity, but significant differences were the exception. It was decided that sampling with 505 μ mesh nets during daylight would provide a representative sample of the available ichthyoplankton assemblage, while at the same time being the most practical and least time consuming with respect to handling, clogging and backflushing. In chapter four, the early life history stages of thiny of the seventy-five taxa sampled are described, reflecting the paucity of information which existed on the ichthyoplankton of the nearshore zone in the south-east Cape. These descriptions are seen as an important contribution towards any future research efforts in the region, but as many of these descriptions are based on few or single specimens, it is realised that the description of egg and larval stages will be an ongoing process. Based upon the data collected during this study, an ichthyoplankton species checklist was established in chapter five. Seventy-five taxa of fish larvae were identified to either family, genus or species level. A number of squid para-larvae were also encountered. Similarities and discrepancies with a previous survey in the region are presented. The temporal distribution of eggs and larvae between August 1993 and October 1996 was established, and the spatial distribution of ichthyoplankton along an offshore transect was determined between January 1995 and May 1996. Only 7 species from Middlebank and twelve from all stations combined displayed seasonal trends, with most of these being prevalent during winter months. Egg production, both over Middlebank and from all stations combined, appeared to be consistent, with no seasonal trends. Based upon the results from the offshore transect samples, it would appear that a single ichthyoplankton assemblage exists from Storms River out to fifteen nautical miles. Although a variety of statistical methods were applied to the data during this study, low egg and larval concentrations and a low sampling frequency meant that results had to be interpreted carefully. Chapter six describes the preliminary investigation into the vertical distribution of eggs and larvae. During two research cruises, discrete depth sampling using an RMT1x6 net was performed, with the majority of samples being accompanied by physical data provided by a CTD rosette sampler. No definite patterns could be seen as larval concentrations were low, and the short time scale did not allow for the identification of any diel migratory patterns. The relationship between total larvae and the physical environment was poor. The only possible relationship was that between plankton volume and total egg and total larval concentrations. The TNP may play an important role in the conservation of reef fish and the seeding of nearby fishing grounds through the export of pelagic eggs and larvae. Chapter seven describes a preliminary investigation into the dispersal potential of ichthyoplankton from the TNP. Based upon longshore currents determined from drogues, ADCP vectors and current meter readings, it was clear that if larvae were passive drifters, the potential for their dispersal from the TNP did exist. This pilot study showed that future work should concentrate not only on the oceanographic aspects, but on behavioural aspects of larvae which may enhance or retard dispersal. In the final discussion, it is emphasised that while this study went a long way to increasing our knowledge of the nearshore ichthyoplankton community, the true picture of the temporal and spatial dynamics of the species assemblage may only be revealed once more intensive sampling has been performed. The resolution of the early life history stages of the sparids and the identification of eggs to species level are seen as priorities for the near future. A complete species checklist for the TNP is provided based upon previous surveys (both on adult and larval fishes), this work and personal observations. A total of 171 species of fish from 70 families were identified, illustrating that the eggs and larvae of many species in the TNP have yet to be sampled. A brief description of the collaborative effort which is envisaged for the TNP over the next few years is provided.

- Description: This study provides a description and critical analysis of the grammatical structure of isiXhosa as used in the Revised Union Version of the Bible, published in 1942 and republished in 1975. This translation records what was regarded as proper isiXhosa at the beginning of the 20th century, reflecting the consensus inter alia of prominent isiXhosa writers, such as W.B. Rubusana, J.H. Soga, C. Koti, Y. Mbali and D. D. T. Jabavu, who served on the committee that produced the revision. In this study isiXhosa is described in its own right, without approaching it with preconceived ideas derived from other languages. That is to say this is a phenomenological analysis describing the grammatical structures of isiXhosa as they present themselves to the analyst. It is comprehensive, with no structure being overlooked or being described in such a manner that it complicates an understanding of other structures. In the first chapter the context of the research and a brief outline of the historical growth in understanding the structure of isiXhosa are set out and the goals and the method followed in this study are described. In the following chapters the findings of this study are presented. The initial focus is on isiXhosa phonology and the orthography used to put it to writing. Then isiXhosa morphology and syntax is set out. Initially the substantives, i.e. the nouns and pronouns in their distinctive classes and forms, and how they are qualified, receive attention. Then the predicates are explored, i.e. the verbs and copulatives, as linked to the substantives with concords, and reflecting various moods, tenses, actualities and aspects. Finally attention is given to ideophones and interjections and words that can be grouped together as adverbs, conjunctions, avoidance words and numerals. In the concluding chapter consideration is given to the question of whether this study has in fact achieved the aim of setting out a description of the structure of isiXhosa based solely on the language itself, free of preconceived ideas, and attention is drawn to insights gained in respect of the true nature of the isiXhosa grammatical structures, such as, for example, the variable prefix qualificative nouns, traditionally referred to as adjectives. This study is therefore a revisionist study in the sense that it reinvents isiXhosa as a language in its own right, free from Western influenced perspectives.

- Description: A number of theoretical and empirically proven studies have shown that the media exert varying degree of influence on audience members. The South African media framing and coverage of foreign nationals is a good example of this. Media critics and scholars hold that the way and manner foreign nationals are represented in South African media landscape contributes to the endemic xenophobic outbreaks in the country. (Endong, 2018; George & Aidoo, 2017). This study aims to critically analyse the influence of media reporting on xenophobic behaviours among students in selected South African universities. Part of its aim is to assert if there exist xenophobic behaviours among students learning in South African universities, which are influenced by the manner in which media reports have stigmatised foreign nationals. Therefore, this study looked at three South African universities, namely the University of Fort Hare, Alice campus, the University of KwaZulu Natal, Howard college campus and the University of Johannesburg, Soweto campus. Data for the study were collected using the qualitative methods, particularly the focus groups discussions and in-depth interviews. The findings of this study have revealed that xenophobic behaviours were evident among students, in lecture-rooms, as well as student residences. The participants also confirmed that the media’s focus and reliance on negative stereotypes and generalized information when representing foreign nationals were the main contributing factors to xenophobic behaviours, including its previous adopting of the words like Amakwerekwere, Aliens and Amagrigamba. In an attempt to discourage xenophobic behaviours, this study has therefore recommended peace journalism and Ubuntu journalism as alternative models for reporting xenophobic violence and conflict.

- Description: This study analysed the current inter-jurisdictional rules in the South African Value-Added Tax (VAT) system, identified shortcomings, and proposed legislative amendments or additions to address these shortcomings. The research was conducted within an interpretative post positivism paradigm, applied a qualitative research methodology, and a doctrinal research method. A detailed review of the literature was conducted to establish the theoretical basis of a good tax system and the theory underpinning indirect and consumption taxation. The literature review also included an in-depth analysis of the South African VAT system and its treatment of resident and non-resident businesses with a South African physical or economic reach, and its treatment of local and cross-border transactions, including imported services. The literature review also considered the international VAT treatment of these transactions. To obtain a wider range of expert opinions regarding shortcomings in inter-jurisdictional rules in the South African VAT system, data was collected through structured interviews with South African and global VAT and indirect tax experts, using a questionnaire that was specifically designed for this purpose. This study proposed amendments and additions to the VAT Act, dealing with the VAT registration of non-resident suppliers; addressing various issues relating to the interjurisdictional VAT rate; proposing measures in connection with imported services; and legislating the intention of the legislator to tax final utilisation or consumption. The study finally recommended the introduction of a general place of supply rule linked to residency; specific place of supply rules for electronic, broadcasting, and telecommunication services; and zero rating provisions for electronic, broadcasting, and telecommunication services provided to non-resident suppliers by resident suppliers for services initiated outside South Africa.

- Description: From Background to the thesis: It has been said that 'educational failure is language failure'. It can be argued here that there are many other factors which could cause educational failure and that language failure does not necessarily result in lack of academic success. However, it is no doubt true that the schoolchild who does not attain a certain type of language competence will be handicapped as regards academic performance. The underlying reason for this is the fact that our educational system is heavily reliant on language - and espacially the written language - as a medium of learning as opposed to the 'direct learning' experiences advocated by certain educationists today such as Ivan Illich in America and John Holt in Britain. Language is the basis both of learning and of communicating what has been learnt. From the moment the child steps into his first period class in the morning till he leaves the last five hours later the child is involved in what is primarily a verbal experience.

- Description: Policy, environmental, social and economic factors are all driving South Africa's transition to sustainable development and a greener economy. Various policies have been developed to foster sustainable development in the post-apartheid era in South Africa (i.e. since 1994) and there are various projections on potential job creation for a green economy. However, there is a problem related to both the achievement of sustainable development and green economy objectives: South Africa is said to lack adequately qualified people to implement these goals resulting in what is termed 'scarce skills' in the environmental and sustainable development sector. This problem has, in turn, prompted various skills development studies in the environmental sector, including a national Environmental Sector Skills Plan produced in 2010. All these studies point to a reactive skills development system that provides inadequate learning pathways for existing and newly emerging green occupations, which provided the impetus for a more proactive, transformative praxis oriented system of skills development that supports environmental learning pathways in South Africa. A second problem is that the concept of 'learning pathway' is poorly defined in the South African environmental education and wider education and training policy context. This term is often used in policy discourse within the notion of 'seamless learning pathways' and is only vaguely defined. This study set out to investigate selected occupationally directed environmental learning pathways in the South African National Qualifications Framework (NQF) and green transitioning context. In attempting to characterise the nature of the environmental pathway, the study utilised critical realist metatheory which serves as an underlabourer for domain specific theory of transitioning societies and systems, life-course transitions and career development. This theoretical work allowed the characterisation of environmental learning pathways as educational and occupational progression. The study investigated the nature of learning and work transitions across the life- course of selected environmental professionals in two key occupational categories - environmental engineer and environmental scientist - both of which have been defined as scarce skills in South Africa. This enabled a nuanced examination of the formation of what emerged as 'boundaryless' career stories of professionals engaged in these two occupations. The study also sought to engage with a methodological problem in learning pathways research, notably that studies are generally framed either at the micro level career story, emphasising agency of individuals (voluntarism), or at the policy level, emphasising structural aspects of the skills development system (determinism). This study sought to bridge the macro-micro problem drawing on critical realist retroductive analysis; this facilitated the shift from a focus on events and experiences that can be empirically observed (captured in case study approaches) to the causal mechanisms influencing environmental learning pathways in these two scarce skill occupations (discussed and analysed using dialectical critical realism), shedding light on how systemic and structural dynamics and mechanisms shape and influence the emergence of learning pathways as experienced in scarce skill occupations in the environmental sector. The opening chapters of the thesis provide an historical view of how the South African education and training system, itself in a transitioning process, has had to grapple with how to respond to and meaningfully take up the new emerging environmental / sustainable development mandate, which is increasingly framed within a multi-levelled transitioning social-ecological system perspective in post-apartheid South Africa. These transitioning systems are shaped by substantive policy imperatives for societal transformation, social justice, sustainable development and equity. Since 1994, various transformations have been taking place, often in paradoxical forms, in both the environmental and educational sectors, shaping a complex multi-levelled transitioning systems perspective for the study. This background work on transitioning systems provides the foundation for the first data chapter, which provides a descriptive outline of key supply side systemic elements as these pertain to environmental learning pathways more broadly (qualifications; occupational framing; career systems; sector skills planning). It also points to the lack of adequate mechanisms for analysing demand for environmental occupations, and highlights some of the contradictions in the supply- demand relation as these pertain to newly emerging environmental occupations. This helps to explain the empirical findings of previous environmental sector studies on the slow and reactive defining of environmental education and training for environmental occupations within the transforming education and training system in South Africa. The next two chapters, using case-based qualitative data, present the analysis of the two scarce skill occupations investigated - environmental engineer and environmental scientist. These chapters outline the dominant institutional educational pathway and the key supply platforms that support these pathways (career guidance; qualifications, occupational framings, skills planning) and the learning and work transitions of professionals within the occupation. The chapters highlight the factors and causal mechanisms influencing these learning pathways and thus provide insight into the multi-level dynamics that underpin learning pathways. The final chapter uses dialectical critical realism to outline generative mechanisms influencing the construction of the learning pathways. It also highlights key absences that are shaping the emergence (or not) of environmental learning pathways, thus pointing to opportunities for how the NQF might respond to the two scarce skill occupations under study, and to the emergence of environmental learning pathways more broadly within the framework of society-in-transition. Through this, the study links the career stories as analysed within the framework of learning pathways and skills system transitioning literature, to generative mechanisms and system development elements. The study concludes with providing occupational and systemic insights into absences and disjunctures that characterise the emergence (or not) of occupationally oriented environmental learning pathways. It also provides insight into what leads to these absences, and how they are kept in place and suggests possibilities and openings for transformative praxis within a multi-levelled transitioning system framework. The study makes the following contributions: At a theoretical level, the study has shown that environmental learning pathways need to be viewed as a complex phenomenon that is emergent in open systems and constituted by dialectically interdependent planes. A deeper understanding of environmental learning pathways is driven by both educational and occupational progression. It utilises key contemporary ideas around learning and work transitions but links them to the broader analyses of transitioning societies influencing the environmental sector, indicating the significance of how environmental education and training system development is situated within the wider transitioning process oriented towards social-ecological sustainability, social justice and greener economies. This study has further identified green skills as an important focus in research work on transitioning societies. At a methodological level, the study has shown how macro-micro and laminated system research can be useful in studying transitioning systems. As a laminated systems study with a focus on transitioning societies, it provides a baseline for further systems study on green work and green skills. At a practical level, the study has made actual contributions to the conceptualisation of learning pathways in the South African NQF context, to building and informing future green skill developments in the South African post-school system, the environmental sector and to informing conceptualising in the emergent Green Skills project.

- Description: This thesis seeks to address a number of troubling concerns related to research and practice in the field of educational technology in South African higher education. Firstly, educational technology research has been criticised for a lack of theoretical rigour resulting in perspectives that are tightly focused mostly on practice but fail to adequately interrogate the socio-political complexities of integrating educational technology. Secondly, while research in the field has been criticised for failing to adequately contextualise the study of educational technology, it also fails to interrogate the impact of colonial legacies and Western-developed technologies on integration practices. Thirdly, there seems to be a disconnect between academics’ practices and choices with educational technology, and the expectations and assumptions of educational technologists. As such, this thesis predominantly follows inductive reasoning where literature and theory are applied to the empirical situation retrospectively in order to avoid the potential influences and biases of mostly Western-driven discourses on educational technology integration practices. Critical realism is used to ‘underlabour’ this study. This meta-theory asserts that there are multiple perspectives of an independent reality, and the work of research is to use these perspectives to draw closer to an understanding of that reality. As such, it allows me to interrogate my perspectives firstly, and secondly those of my research participants, about factors that constrain educational technology integration in the South African context through the use of theory (abstract concepts) and data (research participants’ multiple perspectives). However, critical realism is somewhat cautious in how to access this reality. Therefore, a critical ethnographic epistemology is employed to strengthen critical realism’s aim of accessing knowledge. A critical epistemology emphasises exposing hidden power structures, value judgements as well as self-knowledge and reflexivity. The thesis thus shows how a critical realist ontology could be complemented by a critical ethnographic methodology, particularly in critically-orientated research that has an emancipatory focus which seeks to uncover the socio-political context within which educational technology practices take place. A key argument is that critical realism can be employed as an ontological underlabourer for critical research because of: 1) its immanent critique of traditionally-accepted philosophies, 2) its emphasis on critique of our knowledge claims and value judgements, 3) its insistence that knowledge of the social world necessarily precedes emancipation, and 4) its different conceptions of power (oppressive power and transformatory power). This critical ethnographic research is conducted in a South African university with eight female academics. Data collection is in the form of interviews, observations and reflections, as well as informal and work-related interactions. At each data collection moment, I have had to be reflexively aware of my positionality as an educational technologist, the impact of a colonially-motivated methodology and an ethically-aware approach that seeks to put the needs of the research participants first. Critical ethnography’s meaning-making and critical realism’s abduction and retroduction are used to analyse and make sense of the data. In my attempt to contextualise the study’s findings, I first uncover structural forces and their impact on the academic role before attempting to correlate this with educational technology practices. The study’s findings point to two main structural forces in the socio-political context of South African higher education: the teaching/research tension and the elevation of one dominant culture. In terms of the teaching/research tension, the female academics in this study have to balance the urgent teaching function with the valued research function. They struggle to find this balance because of ambiguous messages from different structures, their passion for teaching, oppressive departmental dynamics and the pressures of their career trajectory. The elevation of one dominant culture is demonstrated through both oppressive cultural practices and untransformed curricula. The study shows that academics mitigate these structural constraints mostly through subtle every day resistance that seeks to mitigate their effect on both the academics and, where applicable, their students. Archer’s morphogenetic/morphostatic cycle is used retrospectively, in response to fieldwork, to conceptualise why this resistance comes about. A resistance framework developed using Archer is then used to understand educational technology choices and practices. The results of the research show that while academics are often pictured as resistant to technology as a response to different barriers, they actually often employ technology to resist structural forces. That is, with this thesis I show that there is a focus on resistance with technology rather than resistance to technology. The study shows how the research participants resist structural forces (teaching tension and dominant culture) by using technology to create safe and responsive learning spaces. As such, this thesis challenges educational technologists to re-think the way they support academics by recommending support strategies that acknowledge both the structural forces in the South African higher education context, as well as the culture of resistance, both of which impact academics’ educational technology choices and practices.
