- Description: In Hogarth's engraved series Industry and Idleness two young men from lower-class backgrounds are apprenticed to Mr West, a weaver. The first plate (1) lays bare the two apprentices' marked difference in temperament: Francis Goodchild works contentedly at his well-lit loom with his 'Prentice's Guide- a standard manual of instruction and advice for London apprentices in various trades - open on the floor below him. In the gloomy foreground Thomas Idle snores crassly at his loom, oblivious of his 'Prentice's Guide, which has apparently been reduced to tatters by the cat that now toys with the abandoned shuttle.

- Description: In southern Africa over the last twenty years, much attention has been given to the importance of NTFPs for rural livelihoods through their household consumption and sale. They have been classified as having either subsistence consumption or commercial values. These values are mostly related to their utilitarian functions, but recent studies show that NTFPs also hold strong cultural functions. Such cultural functions can play a role in both rural and urban livelihoods; consequently the values of NTFPs may be related to both utilitarian and cultural functions. This paper demonstrates the cultural functions of grass brooms in urban areas in South Africa and the impact of their trade on income generation in rural areas, and discusses the concept of culture as a significant factor in the understanding of the role of NTFPs in livelihoods, and their values.

- Description: This article is about narratives, about the forms and meanings constructed by South African storytellers, especially writers and filmmakers. It examines the relationships between examples of these two different narrative forms of literature (fiction and non-fiction) and feature film. Following Turner, the point of departure is that the study of narrative has the potential to provide a framework within which such a two pronged approach can be undertaken. This is not to say that the production of meaning takes place within an exclusive literary or cinematic context. Rather, this approach will allow us to obtain a fuller picture of the narrative of the South African city than is possible by concentrating on one medium. It is based on the premise that narratives are ultimately produced by culture; thus these cultural constructions generate meanings, take on a significance, and assume forms that are articufations of the values, beliefs -the ideology - of the culture.' Literature and film offer specific forms for such narratives. By adopting an interdisciplinary approach which borrows insights from literary and film studies, this article attempts to make a contribution to the fledgling field of South African cultural studies.

- Description: The subgenus Otohime of the triglid genus Pterygotrigla is revised and includes descriptions of six new species (P. amaokai, P. draiggoch, P. elicryste, P. hafizi, P. soela, and P. urashimai) and diagnoses of five previously described species (P. arabica, P. hemisticta, P. multipunctata, P. spirai, and P.tagala). All are poorly represented in museum collections and are distributed in tropical waters of the Indian and western Pacific oceans. The subgenus Otohime is unique within Pterygotrigla in having a very long opercular spine and cleithral spines reduced or absent . The species characters used for identification are the number of joined pectoral-fin rays and second dorsal-rays, colouration of the pectoral fin and first dorsal fin, breast squamation, and number of gill rakers and a few other meristic and morphometric features. Otohime species are very similar in morphometry and meristics and the extent of intraspecific variation is indeterminable from the small collections available. A brief discussion of the genus Pterygotrigla is provided together with its current species composition that is thought to include the unresolved triglid Prionotus alepis. A range extension is given for Pterygotrigla macrorhynchus.

- Description: Both 6-hydroxymelatonin and N-acetyl-N-formyl-5-methoxykynurenamine are photodegradants and enzymatic metabolites of melatonin and are known to retain equipotent activity against potassium cyanide-induced superoxide generation compared to melatonin. It is not clear whether one or both of these metabolites is responsible for this effect. The present study therefore investigates the possible manner in which 6-hydroxymelatonin protects against oxidative stress induced by cyanide in rat brain homogenates. We examined the ability of 6-hydroxymelatonin to scavenge KCN-induced superoxide anion generation as well as lipid peroxidation. In addition, we also examined the effect of this indole on lactate dehydrogenase activity (LDH) as well as mitochondrial electron transport using dichlorophenol–indophenol as an electron acceptor. The results of this study show that 6-hydroxymelatonin significantly reduces KCN-induced superoxide anion generation, which is accompanied by a commensurate reduction in lipid peroxidation. Partial reversal of the KCN-induced reduction in mitochondrial electron transport is accompanied by a similar reversal of mitochondrial LDH activity blunted by KCN. It can thus be proposed that 6-hydroxymelatonin is potentially neuroprotective against KCN-induced neurotoxicity.

- Description: Owners and vendors are increasingly publishing their materials in digital form. Because such materials can be exactly copied, a mechanism is required that will protect the legitimate owners of these works, by providing proof of original ownership. Digital watermarking has now become one accepted method of establishing ownership of digital materials. The owner of a work embeds a pattern, called a digital watermark, in the content. This embedded watermark is normally undetectable, but its presence can be demonstrated by the owner of the work or his agent, thereby proving ownership. Digital watermarking has been used for many types of multimedia content, primarily audio, video and flat images. Recently, interest has been shown in applying digital watermarking schemes to 3D surfaces, in various formats. In this paper, we examine a method whereby a digital watermark can be embedded in a Bezier surface. A prototype watermarking method for such surfaces is presented, with some experimental results, and a discussion of directions for future research.

- Description: Multimedia applications today make use of virtual humans. Generating realistic virtual humans is a challenging problem owing to a number of factors, one being the simulation of realistic hair. The difficulty in simulating hair is due to the physical properties of hair. The average human head holds thousands of hairs, with the width of each hair often smaller than the size of a pixel. There are also complex lighting effects that occur within hair. This paper presents a LightWave 3D plug-in for modeling thousands of individual hairs on virtual humans. The plug-in allows the user to specify the length, thickness and distribution of the hair, as well as the number of segments a hair is made up of. The plug-in is able to add hairs to a head model, which the user then modifies to define a hairstyle. The hairs are then multiplied by the plug-in to produce many hairs. By providing a plug-in that does most of the work and produces realistic results, the user is able to produce a hairstyle without modeling each individual strand of hair. This greatly reduces the time spent on hair modeling, and makes the possibility of adding realistic long hair to virtual humans reasonable.

- Description: mLAN is a networking technology based on the IEEE 1394 standard that allows for the transport of audio and music control data between audio devices. In the original implementation of mLAN, software within each mLAN node hosted by an audio device contained high level plug abstraction and connection management software. mLAN-B is the next generation mLAN architecture that splits the connection management function between workstation and device. The high level connection management and plug abstraction capability resides on the workstation, while a thin low level connection management capability is left on the device. This approach reduces cost and complexity on the device side and ensures that mLAN systems can be easily upgraded.

- Description: In recent years the World Wide Web has transformed into a dynamic, interactive medium, exposing a proliferation of on-line services that dis-tribute large quantities of multimedia. This has increased awareness of the need to select an appropriate Web programming technology when creating Webbased services. This paper compares three dynamic Web programming technologies from the point of view of performance in multimedia distribution. In particular, this paper examines Sun Microsys-tem’s Java Server Pages (JSP), Microsoft’s Active Server Page’s (ASP) and the more recent ASP .NET. The comparison is based on testing applications that distribute multiple images from an Oracle 9i database to Web-enabled clients. Previous research conducted by Oracle indi-cates that JSP and the underlying Java platform outperform ASP. The results in this paper, however, do not agree with Oracle’s statement as JSP tends to be marginally slower than ASP.

- Description: The thesis covers the branches of law known as Constitutional law and Customary law. It focuses on the powers of the Swazi monarch, which are based on a combination of the received Western law and Swazi custom. For the purposes of this study, therefore, Swazi law and custom shall be taken to include both the statutory law and the yet unwritten customary law. Swaziland is black Africa's only remaining traditional monarchy, ruled as it is by the Ngwenyama, an indigenous institution, whose origin is derived from custom. The resilience of this ancient system of government in a continent where modernisation and constitutional democracy among other factors have led to its extinction is phenomenal, particularly because some commentators have described traditionalism in modern Africa as an "embarrassing anachronism.' In Swaziland the monarchy continues to be a vibrant system and the nation is currently engaged in a process of not only codifying the customary law but also of drafting the constitution of the country. One of the key areas of concern is the question of the distribution of power between the monarch and the people under the proposed constitution. Traditionalists are of the view that the powers that the King currently exercises should remain intact as they are a reflection of the Swazi law and custom. Progressives, on the other hand, are of the view that the current position makes the King an absolute monarch and are thus proposing a change from an absolute to a constitutional monarch. In other words they want some kind of checks and balances in the envisaged system of government. The study will show that the constitutional evolution of Swaziland and the exigencies of synthesising modern and traditional systems of governance have over the years obscured the true nature of the powers of the monarch in terms of Swazi custom. Thus before we can consider whether the future of the monarchy in Swaziland depends on the harmonisation of modern and traditional systems of governance, it is necessary to revisit the past to determine the powers of the monarch in their embryonic form, for it is from this period that we can extrapolate the powers of the Ngwenyama in terms of Swazi custom. The thesis has been arranged as follows: The first chapter will review the precolonial political system of Swaziland with a view to establishing whether monarchical authority was founded on command or consensus. The various theories, which seek to explain the foundations of the monarchical system of government, will be outlined. The second chapter will focus on European influence on the Swazi traditional system of government. The third chapter will be an analysis of the powers of the monarch under the 1968 independence constitution. The fourth chapter will focus on the effect of the repeal of the 1968 independence constitution by the Monarch. The fifth chapter will focus on the constitutional reforms under the reign of king Mswati III. The sixth and last chapter focus on proposals for reform. The research method used was in the main, an analysis of relevant legal principles as contained in textbooks, legislation, journals, the scant case law that is available in this area of the law and other relevant materials. A comparative survey of ancient African kingdoms will be done, with emphasis on those Kingdoms, which later became British colonial possessions. It is hoped that this comparative analysis will help explain the evolution of these traditional structures alongside modern governmental institutions.

- Description: In order to understand the effects of metals contained in effluent and to define effluent quality suitable for safe discharge to natural water streams, it is essential to understand the effects of the interaction of metal ions with plants. The availability of metal ions and their ability to bind to plants are dependent on the chemical speciation of metals and on the biological factors governing the availability of metals within the plant cells. This thesis will address both aspects and thereby propose a combination of an appropriate chemical and biological approach to the investigation of bioaccumulation of the plant Azolla Filiculoides. Laboratory studies have shown that varying concentrations of free metal ions in solution determine efficiency of metal uptake and that metal toxicity can also be detrimental to plant life and efficiency of metal recovery from solution. Many questions however, remain unanswered with regard to the application of a biological treatment for effluent discharge. This thesis includes the determination of metal speciation combined with the study of bioaccumulation of metals in plants and their effects from test- work utilising effluent generated from a Precious Metals Refinery (PMR). Plant species are known to differ widely in their tolerance to metals, however despite an abundant knowledge on molecular, biochemical and physiological effects of metals to plants, only a few general principles have been proposed to guide the prediction of tolerance differences. The properties of protective cellular responses as well as of the molecular target sites are important components in determining the intrinsic tolerance of a particular species to a metal. The role of the whole assembly of cellular ligands in buffering metal ions within the cells will be evaluated. Standard preparation methods combined with use of Inductively Coupled Plasma Emission Spectrophotometer (1CP) used for analytical analysis will be included to reflect analytical data in providing evidence to support a conclusion. The outcome of the test work utilising the aquatic plant Azoila has proven that it can be used as a process step to re-mediate effluent generated from Precious Metal Refining operations. This process offers an alternative to the classical chemical methods widely used in the Precious Metals Refining industry proving economically viable and ensuring environmental sustainability in comparison to the current known methods of effluent treatment. , Thesis (MSc) -- Faculty of Science, Biochemistry, Microbiology and Biotechnology, 2003

- Description: [From the introduction]: Most male cicadas produce a calling song in order to attract conspecific females. These songs have been shown to differ in closely related species (e.g. Alexander & Moore 1962; Villet 1988, 1989; Boulard 1995; Marshall & Cooley 2000; Sanborn & Phillips 2001) and in species which share habitats (e.g. Sueur 2002). The former is an inevitable part of the divergence of recognition signals that characterizes the speciation process in animals using acoustic signals (Villet 1995), while the latter would be expected from a signal that acts as a reproductive isolating mechanism (Claridge 1985; Marshall & Cooley 2000). Calling songs are therefore of value in resolving taxonomic problems in the cicadas.

- Description: Organising new and maintaining existing members is central to the strength of trade unions. In a context where union densities are in decline across the world, the focus on organising, and especially on maintaining members, has increased. To maintain membership, unions are increasingly focusing their attention on the provision of services to members. The September Commission report and the Congress of South African Trade Unions (COSATU) National Congress in 2000 resolved that there must be organisational renewal within COSATU affiliates. Organisational renewal includes providing members with a high level of service. Resolutions envisaged each COSATU affiliate establishing capacity to monitor service delivery to members on a regular basis and deal with problems and complaints as soon as they arise. Improved service starts by listening to members and understanding what they want, why they joined the union and how the union addresses their needs, both at the workplace and, more broadly, in society as a whole. This survey was undertaken to assist four affiliates in evaluating their members’ perception of the service that they receive from their union.
