- Description: When I proposed to 26 third-year journalism students that our writing class take inspiration from an idea pioneered in places as unfashiona-ble and inhospitable as the former Soviet Union and Nepal, I should have expected the icy stares. But happily, within five weeks, this winter of classroom discontent, had begun to thaw into a tentative spring of journalistic and pedagogical innovation.

- Description: Thermal responses were measured in cicadas collected in the Eastern Cape Province of South Africa. The thermal responses of 22 species from 5 biomes were determined. Shade-seeking temperature was the most variable and related to the various biomes. Mean shade-seeking temperature was greatest for species inhabiting the thicket biome and lowest for species inhabiting the forest biome. The animals that live in the thicket biome may adapt to the greater thermal stress to take advantage of a habitat that permits lower predation pressure. There is a correlation between body size and shade-seeking temperatures with smaller species exhibiting lower thermal responses within a particular habitat. This may be related to the greater heat exchange in smaller species. Heat torpor temperatures did not differ between the various biomes.

Those merry, tinkling, tuneful bells : handbells in Victorian Grahamstown with a note on bell ringing at Grahamstown Cathedral

- Description: [From the introduction]: The idea of using sets of small bells tuned to particular notes in order to produce music is very old. There are illustrations of slung bells being played in this way from the 11th and 12th centuries. Bell ringers in England date the sue of sets of tuned and hand-held bells from as early as the 16th century though it seems that the modern handbell may have come into existence in the early 18th century. Such bells were used by tower bell ringers as convenient practice devices for change ringing. The ringing of tunes on handbells became popular in the 18th century and reached its heyday in the latter half of the 19th century. In England tune ringing was especially popular in the north and major competitions had their centre at Manchester. Special trains were run to competitions there and bands, ringing up to 200 bells, could find their skills tested on extracts from Mozart's Don Giovanni. World War I and the spread of alternative media of entertainment like radio put an end to ringing on this scale. , This publication marked the 150th Anniversary of the Diocese of Grahamstown. Michael Berning was a member of the Rhodes University Library staff from 1965 until his retirement in 1997. He was Tower Captain of the Grahamstown Cathedral during the 1980s.

Towards a norm in South African Englishes: the case for Xhosa English

- Description: Black South African English (BSAE) is generally regarded today as the variety of English commonly used by mother-tongue speakers of South Africa's indigenous African languages in areas where English is not the language of the majority. Its roots lie in the history of the teaching of English to the black people of this country, where the role models who teach English are second language learners themselves. To date, BSAE has mainly been studied within an applied linguistic framework with emphasis on its character as a second language which is deviant from standard English. An alternative view is to see it as a variety in its own right, a new or world English (Coetsee Van Rooy and Verhoef, 2000; van der Walt and van Rooy, 2002). As a consequence, a new look at norms is becoming increasingly necessary, so that decisions about learners' language competence can be made in terms of this variety. This paper reports on preliminary analyses of a recently collected corpus of Xhosa English (XE) (a sub-category of BSAE) which consists of naturalistic spoken data, and comprises some 540,000 words of Xhosa English. This large database enables empirical analysis of actual patterns of use in language, making it possible to test earlier speculations which have been based on intuition, and to explore the possibility of systematic differences in the patterns of structure and use in this particular variety. The paper focuses on 20 separate linguistic characteristics, most of which have been previously identified in the literature as being features of BSAE, and analyses each of them in turn, in order to ascertain their usage patterns and frequency of occurrence in the corpus.

Transcendence in Patrick White: the imagery of the Tree of Man and Voss

- Description: This study represents an exploration of White's concept of transcendence in The Tree of Man and Voss by means of a detailed account of some of the key patterns of imagery deployed in these novels. White's imagery is a key mode of expression in his work, not simply manifesting in overarching religious symbols and framing structures but figuring in constantly modulated tropes continuous with the narrative, as well as in minor, but no less significant images occasionally susceptible to etymological or onomastic reading. While no attempt is made to provide an exhaustive exploration of the tropes at work in these novels, a sufficient range of material is covered, and its metaphoric density adequately penetrated, to highlight and explore a fundamental concern in White's work with a paradoxical unity underlying the dualities inherent in temporal existence. A useful way of approaching his fiction is to view the perpetual modulations of his imagery as the dramatisation of an enantiodromia or play of opposites, in which the conflicts of duality are elaborated and paradoxically - though typically only momentarily - resolved. This resolution or coincidence of opposites is a significant feature of his notion of transcendence as well as his depictions of illuminatory experience, and in this respect White's metaphysics share an essential characteristic, not only of Christianity, but a range of religious and mythological systems concerned with expressing a transcendent reality. Despite these analogies, however, the novels at hand are not so tightly bound to Christian, or any other, meaning-making systems so as to constitute sustained allegories, and hence this study does not aim to chart a series of correspondences between White's images and biblical or mythological symbols. Indeed, a criticism often levelled at White - with The Tree of Man and Voss typically figuring in support of this claim - is that he too rigidly imposes religious frameworks on his work. An extension of this view is formulated in the Jungian critique of White's corpus offered by David Tacey, who argues that White's conception of transcendence is consistently challenged by the archetypal significance of the images he employs, which point to a contrary process of psycho-spiritual regression in his protagonists. In a fundamentally text-based approach, this study explores White's use of imagery while taking biblical resonances and archetypal interpretations into account, and suggests that, though White's images are highly allusive, they are not merely agents of imported Christian, or other traditional symbolic values. Nor do they undermine the authenticity of his depiction of the spirituality of his protagonists, or obtrude on the fabric of the narrative. Instead, the range of his images are - though often ambivalent - integral to a network of mercurial tropes which articulate and constantly evaluate a notion of transcendence through inflections and oscillations rather than equations of meaning.

- Description: The National Water Policy (DWAF, 1997). and the National Water Act (No 36 of 1998)(NWA) provide the legal and management context for the application of results. The law and the policy are founded on the concepts of equity (fairness of access to water and water services) and sustainability (the opportunity to optimally use water resources now and into the future)(NWA, l (l)(xviii)(b)). The concept of sustainability is based on the understanding that on earth water comes packaged in aquatic ecosystems, and that the product, water, is intimately related to and affected by the structure and functioning of these ecosys-tems.(Aquatic ecosystems include rivers, lakes, wetlands, aquifers and estuaries. Impoundments act as artificial lakes connected to river sys-tems.) A key recognition during the development of the policy and the NWA was that" the environment" does not compete with users for re-sources-the environment (in this case aquatic ecosystems) is the re-source. Therefore a key poiicy of DWAF is that vi resource protection in order to achieve sustainable resource use. Resource protection is achieved through the implementation of resource directed measures (RDM) and source directed controls (SDC).

Versions of confinement: Melville's bodies and the psychology of conquest

- Description: This thesis explores aspects of Melville’s presentation of both the whale and the human bodies in Moby-Dick and human bodies in other important novels. It argues that Melville uses his presentation of bodies to explore some of the versions of confinement those bodies experience, and by doing so, analyses the psychology which subtends that confinement. Throughout Melville’s works bodies are confined, both within literal spatial limits and by the psychology which creates and/or accepts these spatial limits. The thesis argues that perhaps the most important version of bodily confinement Melville addresses is the impulse to conquer bodies, both that of the other and one’s own. It adopts a largely psychoanalytic approach to interpreting bodies and their impulse to conquer, so that the body is seen to figure both in its actions and its external appearance the operations of the inner psyche. The figure of the body is equally prevalent in Melville’s exploration of nationalist conquest, where, as with Manifest Destiny and antebellum expansionism, the psychological and physical lack experienced by characters can be read as motivating factors in the ideology of conquest. A final important strand of the thesis is its argument in favour of a gradual shift in Melville’s interpretation of the value and possibility of genuine communion between human beings and between humans and the whale. One may read Typee as an attempt by Melville to explore the possibility of a this-worldly utopia in which human beings can return to a version of primitive interconnectedness. This exploration may be seen to be extended in Moby-Dick, particularly in Ishmael’s attempts to find communion with others and in some moments of encounter with the whales. The thesis uses phenomenology as a theory to interpret what Melville is trying to suggest in these moments of encounter. However, it argues, finally, that such encounter, or ‘intersubjectivity’ is eventually jettisoned, especially in the works after Moby-Dick. By the end of Melville’s life and work, any hope of an intersubjective utopia he may have harboured as a younger man have been removed in favour of a refusal actually to assert any final ‘truth’ about social, political or even religious experience. Billy Budd, his last body, is hanged, and his final word is silence.

These volcanic sequences are of late-Archaean to early-Proterozoic age and are amongst the oldest supracrustal volcanic sequences erupted onto the Archaean Kaapvaal craton. The volcanic rocks have suffered low-grade greenschist facies metamorphism but primary textures and, in some samples, primary mineralogies are well preserved.

The basic lavas are relatively rich in SiO2 (50–58%) and aphyric and exhibit a large compositional range. This variation is typically tholeiitic in that it is characterized by strong enrichment of Ti, Fe, and V in differentiated lavas.

- Description: This paper explores a discourse of war against HIV/AIDS evident in the Daily Dispatch, a South African daily newspaper, from 1985 to 2000, and discusses the implications of this in terms of the way in which HIV/AIDS is constructed. The discursive framework of the war depends, fundamentally, on the personification of HIV/AIDS, in which agency is accorded to the virus, and which allows for its construction as the enemy. The war discourse positions different groups of subjects (the diseased body, the commanders, the experts, the ordinary citizens) in relations of power. The diseased body, which is the point of transmission, the polluter or infector, is cast as the 'Other', as a dark and threatening force. This takes on racialised overtones. The government takes on the role of commander, directing the war through policy and intervention strategies. Opposition to government is couched in a struggle discourse that dove-tails with the overall framework of war. Medical and scientific understandings pre-dominate in the investigative practices and expert commentary on the war, with alternative voices (such as those of people living with HIV/AIDS) being silenced. The ordinary citizen is incited to take on prevention and caring roles with a strong gendered overlay.

Water resources in Botswana with particular reference to the savanna regions

- Description: Production and development in the savanna regions of southern Africa are primarily determined by interactions between the limitations imposed by ecological determinants (such as rainfall and soil quality) and the management strategies of the specific region. Good planning, focussing on both the short and long-term effects of water use, is needed in water management strategies. Botswana is already experiencing so-called 'water stress' which is related to a number of factors such as rapidly increasing population leading to a sharp increase in water demand, low and variable rainfall, high rates of evaporation, and the high cost of exploiting existing water resources. At the current rates of abstraction, the lifetime of surface and groundwater resources is limited to decades. Botswana shares four river basins with its neighbouring countries. This results in a situation where 94% of the fresh water resources which Botswana can theoretically access originates outside its borders, making water resource management highly complex. Transnational sharing and management of water resources, therefore, plays a major role in securing sustainability of this precious resource.

Where the global meets the local : South African youth and their experience of global media
- Authors: Strelitz, Larry Nathan
- Date: 2003

- Description: Within the context of debates concerning the impact of global media on local youth, this study explores how a sample of South African youth responds to texts which were produced internationally, but distributed locally. Recognising the profound rootedness of media consumption in everyday life, the research examines the way these youth, differentially embedded in the South African economic and ideological formation, use these texts as part of their ongoing attempts to make sense of their lives. The study rejects the 'either/or' formulations that often accompany competing structuralist and culturalist approaches to text/audience relationships. Instead, using a combination of quantitative and qualitative research methods, it seeks to highlight the interplay between agency and structure, between individual choice and the structuring of experience by wider social and historical factors. The findings of the study point to the complex individual and social reasons that lie behind media consumption choices, and the diverse (and socially patterned) reasons why local audiences are either attracted to, or reject, global media. These and other findings, the study argues, highlight the deficiencies of the media imperialism thesis with its definitive claims for cultural homogenisation, seen as the primary, or most politically significant, effect of the globalisation of media. As such, this study should be read as a dialogue with those schools of thought that take a more unequivocal point of view on the impact of globalised media culture.

- Description: Density, population structure, growth, mortality and aspects of reproduction of the non-native amphipod Platorchestia platensis were studied for 20 consecutive months (October 2008 to May 2010) in the supralittoral wrack of the Knysna Estuary, South Africa. Amphipod density varied over the sampling period with the lowest numbers recorded in summer (January and February). Ovigerous females with embryos, and juveniles were found in most months with peaks in recruitment found in both April and October, suggesting that in Knysna this species is a biannual breeder. Average female size was significantly greater in winter, with larger females tending to brood more embryos. The largest adults (13.5 mm total length) were always male although the monthly sex ratio was nearly always female biased. Growth rate estimated from a cohort analysis was about 1 mm per month and monthly survival about 69%. The ability to reproduce all year round may be one reason why this introduced species has become established within this warm temperate estuary.
