- Description: This thesis presents a Virtual Sculpting system, which addresses the problem of Free-Form Solid Modelling. The disparate elements of a Polygon-Mesh representation, a Directly Manipulated Free-Form Deformation sculpting tool, and a Virtual Environment are drawn into a cohesive whole under the mantle of a clay-sculpting metaphor. This enables a user to mould and manipulate a synthetic solid interactively as if it were composed of malleable clay. The focus of this study is on the interactivity, intuitivity and versatility of such a system. To this end, a range of improvements is investigated which significantly enhances the efficiency and correctness of Directly Manipulated Free-Form Deformation, both separately and as a seamless component of the Virtual Sculpting system.

Where are the men? : an investigation into female-headed households in Rini, with reference to household structures, the dynamics of gender and strategies against poverty
- Authors: Brown, Brenda

- Description: An in-depth study is conducted into ten female-headed households in the township of Rini, an underprivileged section of Grahamstown in the Eastem Cape region of South Africa. The study provides information on the way in which such households function in conditions of poverty and underemployment. The meaning of the term 'household' is clearly defined. A household consists of a group of people, who may or may not be kin-related, but who usually live under the same roof, eat together and share resources. Household members may be absent for varying periods of time, but are still considered to have rights in the household to which they belong. The female-headed household usually contains a core of adult women who are often uterine kin. Men are frequently members of these households and are usually related to the women who form the core. Their status and roles in such households are defined and intra-household relations between household members are discussed. In this study, female headship is observed to occur in conditions of poverty when an elderly woman is widowed, receives a regular income in the form of and old age pension, and when her status as the senior member of the household is acknowledged. The presence of men in female-headed households has not been widely emphasised in other studies, either of the female-headed household itself, or in research done in this area of South Africa. An attempt is therefore made to illustrate the way in which men function in these households and the varying roles they play. An attempt is also made to describe other structures and practices which support the female-headed household in a rapidly changing urban environment. These include church membership, burial society membership, the informal economy, wider kinship networks and, in the case of the men, the rite of circumcision.

White writers and Shaka Zulu
- Authors: Wylie, Dan
- Date: 1996
- Subjects: Shaka, Zulu Chief, 1787?-1828 In literature Shaka, Zulu Chief, 1787?-1828 Zulu (African people) -- History
- Language: English
- Type: Thesis , Doctoral , PhD
- Identifier: vital:2233 , http://hdl.handle.net/10962/d1002276
- Description: The figure of Shaka (c. 1780-1828) looms massively in the historical and symbolic landscapes of Southern Africa. He has been unquestioningly credited, in varying degrees, with creating the Zulu nation, murderous bloodlust, and military genius, so launching waves of violence across the subcontinent (the "mfecane"). The empirical evidence for this is slight and controversial. More importantly, however, Shaka has attained a mythical reputation on which not only Zulu self-conceptions, but to a significant degree white settler self-identifications have been built. This study describes as comprehensively as possible the genealogy of white Shakan literature, including eyewitness accounts, histories, fictions and poetry. The study argues that the vast majority of these works are characterised by a high degree of incestuous borrowing from one another, and by processes of mythologising catering primarily to the social-psychological needs of the writers. So coherent is this genealogy that the formation of an idealised notion of settler identity can be discerned, especially through the common use of particular textual "gestures". At the same time, while conforming largely to unquestioning modes of discourse such as popularised history and romance fiction, individual writers have attempted to adjust to socio-political circumstances; this study includes four close studies of individual texts. Such close stylistic attention serves to underline the textually-constructed nature of both the figure of Shaka and the "selves" of the writers. The study makes no attempt to reduce its explorations to a single Grand Unified Explanation, and takes eclectic theoretical positions, but it does seek throughout to explore the social-psychological meanings of textual productions of Shaka - in short, to explore the question, Why have white writers written about Shaka in these particular ways?
