- Description: The purpose of this project was the specification, design and implementation of a prototype 2-D MPEG-4 authoring tool. A literature study was conducted of the MPEG-4 standard and multimedia authoring tools to determine the specification and design of a prototype 2- D MPEG-4 authoring tool. The specification and design was used as a basis for the implementation of a prototype 2-D MPEG-4 authoring tool that complies with the Complete 2-D Scene Graph Profile. The need for research into MPEG-4 authoring tools arose from the reported lack of knowledge of the MPEG-4 standard and the limited implementations of MPEG-4 authoring tools available to content authors. In order for MPEG-4 to reach its full potential, it will require authoring tools and content players that satisfy the needs of its users. The theoretical component of this dissertation included a literature study of the MPEG-4 standard and an investigation of relevant multimedia authoring systems. MPEG-4 was introduced as a standard that allows for the creation and streaming of interactive multimedia content at variable bit rates over high and low bandwidth connections. The requirements for the prototype 2-D MPEG-4 authoring system were documented and a prototype system satisfying the requirements was designed, implemented and evaluated. The evaluation of the prototype system showed that the system successfully satisfied all its requirements and that it provides the user with an easy to use and intuitive authoring tool. MPEG-4 has the potential to satisfy the increasing demand for innovative multimedia content on low bandwidth networks, including the Internet and mobile networks, as well as the need expressed by users to interact with multimedia content. This dissertation makes an important contribution to the understanding of the MPEG-4 standard, its functionality and the design of a 2-D MPEG-4 Authoring tool. Keywords: MPEG-4; MPEG-4 authoring; Binary Format for Scenes.

- Description: Two ant species, Pheidole megacephala (Fabricius) and Anoplolepis custodiens (Smith) reach pest status in citrus orchards through precipitating outbreaks of homopterous pests. However, predacious ants, including these two ant species, play an important role in pest suppression in agroecosystems and are therefore beneficial to these systems. If A. custodiens and P. megacephala are important natural control agents in citrus, using ant bands to break the mutualism between the ants and the Homoptera as a method of ant control is preferable to poisoning. Ant communities were sampled by pitfall trapping in three experimental subunits of 2-, 4-, 15- and 30-year-old citrus orchards, in the Grahamstown area of the Eastern Cape. In one subunit in each orchard, populations of P. megacephala and A. custodiens were suppressed by poison applications. In a second subunit, trees were banded with trunk barriers so that ants were prevented from foraging in the trees and a third subunit served as the untreated control. Bait pupae of bollworm, false codling moth and fruit fly were planted in bait trays in all of the subunits to investigate predation on these citrus pests in the relative absence of predacious ants and where they were excluded from the trees. Pheidole megacephala dominated exclusively in all of the plots. Community composition did not change dramatically with increasing age of the trees, but species diversity and species abundance did. Rank-abundance curves showed that community diversity was highest in the 2-year-old plots and lowest in the 30-year-old plots. The Simpson and Shannon-Wiener diversity indices and their evenness measures indicated that diversity and equitability were highest in the poisoned subunits and lowest in the banded subunits. Principle component analysis revealed that the poisoned subunits were similar and distinct in species composition, that there was significant monthly variation in species composition and that community stability increases with an increase in orchard age. The presence of P. megacephala was significantly negatively correlated (rs = -0.293; p < 0.001) with pest pupal survival. Pupal survival was significantly higher for bollworm (p < 0.001), FCM (p < 0.001) and fruit fly (p < 0.001) in the poisoned subunits, than in the banded and control subunits. There was a general trend for survivorship to increase with an increase in the age of the trees. A significant difference (p < 0.001) was found between the months in which the trials were carried out. Pupal survival was significantly lower (p < 0.001) for FCM than for bollworm and fruit fly. In citrus orchards, ant communities are organised by ecological processes and interactions and are influenced by methods of ant control. Ant bands are preferable to poisoning as a method of ant control, so that beneficial species are left on the ground to prey on pests that pupate in the soil. Maintaining high ant species diversity in citrus orchards would be beneficial as predation on the pupae was more effective where ant species diversity was higher.

- Description: The number of women who choose to combine careers and traditional roles as mothers has been increasing steadily over the last number of years. As a result, the subjective wellbeing of these women has been the focus of many research projects over the last number of years. Subjective well-being has been defined in various ways by different authors. One definition describes subjective well-being as people's evaluations of their lives, which includes happiness, pleasant emotions, life satisfaction, and a relative absence of unpleasant moods and emotions. The current study, which took the form of a multiple case study, attempted to explore and describe White employed married mothers’ subjective experience of their well-being. The study also explored these women's experiences of combining the roles of employee and motherhood. The sample was obtained through the snowballing technique, and both qualitative (in-depth interviews) and quantitative techniques (two questionnaires - the Satisfaction with Life Scale and the Beck Depression Inventory) were utilized. The analysis of the data that was gathered was done by means of thematic and content analyses.

- Description: Lantana camara Linnaeus (Verbenaceae), commonly known as lantana, is a highly invasive weed in many parts of the world. In South Africa it is naturalized in several provinces where it invades pastures, riverbanks, mountain slopes and valleys and commercial and natural forests, forming dense, impenetrable thickets. Chemical and mechanical control methods are expensive, labour intensive and provide only temporary relief as cleared areas are rapidly reinfested by seedlings and coppice growth. A biological control programme was initiated in South Africa in the 1960s, but despite the establishment of 11 agent species, it was considered to have had limited success. Several factors are thought to restrict the impact of the biocontrol agents. Firstly, L. camara occurs in a range of climatic regions, some of which are unsuitable for the establishment of agent species of tropical and subtropical origin. Secondly, L. camara is the result of hybridization between several Lantana species, forming a complex of hybridized and hybridizing varieties in the field, which match none of the Lantana species in the region of origin. This causes partial insect-host incompatibility, displayed as varietal preference. Thirdly, parasitism appears to have significantly reduced the effectiveness of several natural enemies. In spite of all these constraints, biological control has reduced invasion by L. camara by 26%. However, the weed is still very damaging and additional natural enemies are required to reduce infestations further. A flea-beetle species, Alagoasa extrema Jacoby (Coleoptera: Chrysomelidae), was collected from several sites in the humid subtropical and tropical regions of Mexico, and imported into quarantine in South Africa and studied as a potential biocontrol agent for L. camara. Favourable biological characteristics of this beetle included long-lived adults, several overlapping generations per year, and high adult and larval feeding rates. Observations from the insect’s native range and studies in South Africa suggest that A. extrema would probably be more suited to the subtropical, rather than the temperate areas in South Africa. Laboratory impact studies indicated that feeding damage by A. extrema larvae, over a period spanning the larval stage (16 to 20 days), reduced the above-ground biomass of L. camara plants by up to 29%. Higher larval populations resulted in a higher reduction of biomass. Varietal preference and suitability studies indicated that A. extrema exhibits a degree of varietal preference under laboratory conditions, with one of the white pink L. camara varieties proving the most suitable host. This variety is one of the most damaging varieties in South Africa and is particularly widespread in Mpumalanga Province. Although A. extrema proved to be damaging to L. camara, laboratory host range trials showed it to be an oligophagous species, capable of feeding and developing on several non-target species, especially two native Lippia species (Verbenaceae). The host suitability of these species was marginally lower than that of L. camara and the potential risk to these indigenous species was deemed to be too high to warrant release. It was therefore recommended that A. extrema not be considered for release in South Africa.

- Description: The new government faced enormous challenges when it came into office in 1994. For starters, the outgoing Apartheid leaders had thoroughly plundered the state coffers, awarding themselves and white civil servants massive pensions and 'golden handshakes'. The budget deficit was almost 9% of GDP The country/ had barely three weeks foreign exchange reserves, with a balance of payments crisis looming. The majority of inherited civil servants were generally hostile to the new government. The 'deep structures' of the State — by which I mean the ingrained habits and behaviour — were also generally hostile to the objectives of the democratic State. In addition, poverty levels were very high, and income inequality was among the worst in the world. And, of course, South Africa had the most institutionalised forms of racism in the world, which permeated through every law' and practice.

- Description: The Creative Solutions to Waste Project (CSW) is a local environmental education project, involving five Grahamstown schools, the local municipality; community members and the Rhodes University Environmental Education Unit, where I worked at the time this study was undertaken. In this research I explore the use of environmental education learning support materials (LSM) in Outcomes Based Education (OBE). I have employed a participatory action research approach informed by critical theory in this case study of the Creative Solutions to Waste project (CSW). The research focused on the ‘Waste Education’ materials and their use, developed and piloted during the pilot phase. The Waste Education materials were also used in phase one. In phase two, the research focused on the use of ‘Health and Water’ learning support materials in 4 Grahamstown schools. Research participants included educators, support team members, municipal officials, Department of Education officials, Department of Health (Eastern Cape) officials, the Health Promoting Schools committee and NGO representatives. I employed a range of data collection strategies including questionnaires, observations, field notes, semi-structured interviews, focus group interviews, workshops, reflective journal, videotapes, and photographs and documents analysis. The research process was collaboratively discussed and agreed upon by all the participants. This research indicated that the purpose influences the use of LSM. It also indicated the importance of mediation processes in the use of LSM. This study indicates that the designs of LSM and particular views of learning influence the way LSM are used. It does that by looking at how an active learning framework influenced the use of learning support materials and consequent learning processes. It also highlights the significance of paying attention to issues of language and literacy in the design of LSM, and how these factors influence the use of LSM. It also identified the tension between prescriptive and open-ended processes to professional development in supporting the use of LSM in contexts of curriculum change and transformation. This study also indicated the importance of reflexive processes to improve support process in the CSW project by demonstrating how the contributions and the roles of the support team were reflexively changed. I have reviewed the research processes in relation to the research design decisions made at the start of the project. This study lastly offers some recommendations for further research into the use of LSM, and how an understanding of LSM use may influence the development of LSM.

- Description: This study explored the use of social work services by East London attorneys in criminal law matters. Semi-structured interviews were conducted and the data was saturated after 10 such interviews. In exploring the use of social work services, the study also considered the challenges and constraints experienced by lawyers in their use of expert witnesses from the Humanities generally; discussed the expectations lawyers have of expert witnesses and the presentencing reports they write and described the perceived impact of social work services on the presentation of cases in criminal matters. The focus on social work was aimed at exploring ways of increasing the use of social work as the profession of choice when attorneys call on expert witnesses. The literature revIew focussed on the individualisation of sentences, the general principles of punishment, finding an appropriate sentence, the so-called Triad of Zinn, the role of the social worker in criminal justice, the role of the legal social worker, the report, courtroom skills and the relationship between social work values and the law. Using purposive sampling of all legal firms in East London doing criminal work, ten attorneys were asked to participate in the study. A semi-structured interview based on a schedule of questions was used. The interviews were recorded and transcribed. The transcripts were analysed thematically. After ten interviews no new data was being generated and the topic was considered saturated. Further research is needed to build on the themes that emerged. The study argues that there is a place for social work services in criminal matters. It also, however, revealed that some of the respondents had had negative experiences when dealing with social workers. There were also positive responses and a commitment to establishing a more co-operative relationship between law and social work. Based on the research findings, the most important recommendation was to develop communication between the two professions and to provide inter-disciplinary training so as to promote an understanding of the roles and expectations of all involved in the criminal law process.

- Description: The Internet has provided marketing with many new tools and given old tools new or improved meanings. The Net poses tremendous challenges for scholars in many lines of research, from usability studies and consumer behaviour research to marketing and advertising research. Because the World Wide Web (the Web) presents a fundamentally different environment for marketing activities than traditional media, conventional marketing activities are being transformed, as they are often difficult to implement in their present form. This means that in many cases these marketing activities have to be reconstructed in forms more appropriate for the new medium. A lot of technological changes have affected the marketing environment of today. Companies must adapt to these changes in order to improve their marketing strategies. This has, among other things, resulted in an emphasis on relationship marketing. The purpose of this thesis is to explore what strategies are used in practice by companies in order to market and promote their products and services by using their Web sites as well as to build effective Customer Relationship Management (CRM). In order to fulfil the research purpose, interviews were conducted at a number of companies (medium and large), and questionnaires were mailed to various companies in the motor retail industry. The result shows that a company can use traditional as well as online marketing and promotion strategies when conducting business. This can also help companies to gain better relations with their customers. The different marketing and promotion strategies are useful for attracting new business as well as maintaining and stimulating existing relations. The research problem addressed in this study was to determine the factors that are effective in marketing and promoting of Web sites as well as the methods used in building CRM.

- Description: The study which follows considers the current approach to State sovereignty, use of force, and human rights, in order to determine the balance which exists between these concepts. A shift in this balance determines the direction of development of the concept of ‘humanitarian intervention.’ The investigation establishes that State sovereignty and certain human rights are at a point where they are viewed as equal and competing interests in the international arena. This leads to the question of whether or not the concept of humanitarian intervention has found any acceptance in international law. It is determined that the right to intervention rests exclusively with the United Nations Security Council. There are, however, obstacles to United Nations action, which necessitate either taking action to remove the obstacles, or finding an alternative to United Nations authorized action. The alternatives provided are unilateral interventions by regional organizations, groups of States or individual States, with interventions by regional organizations being favoured. The study further discusses the requirements which would make unilateral action more acceptable. These same requirements provide a standard against which the United Nations can measure its duty to intervene. Such an investigation was done by the International Commission on Intervention and State Sovereignty, and a synopsis of its Report and Recommendations are included. Finally, the question of responsibility is addressed. State and individual responsibility for two separate types of action are considered. The responsibility of States and individuals for initiating an intervention is considered under the topic of the crime of aggression. The responsibility of States and individual for exceeding the mandate of a legitimate intervention is considered under the heading of war crimes.

- Description: The Brenton blue butterfly is known only from a small population in one hectare of asteraceous coastal fynbos at Brenton-on-Sea. This fynbos is characterized by a great diversity of shrubs, herbs and graminoids, with a successional gradient to thicket where Pterocelastrus tricuspidatus is dominant. The eggs of the butterfly are laid on the lower side of the leaves of Indigofera erecta, on which the larvae feed. Fifteen 1-m² quadrats containing plants of Indigofera erecta with and without eggs of the butterfly were distinguished and sampled separately from 15 1-m² quadrats containing plants of Indigofera erecta without eggs. No marked differences in total vegetation, shrub or herb cover between the sites with and without eggs were observed. There was a difference in abundance of the fern Pteridium aquilinum, with over 30% cover at sites with no eggs and only about 6% at sites with eggs present. This could reflect the absence of other plants where the ferns had such dense cover.

- 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.

- 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.

The role and function of the educational psychologist was researched through literature study and empirical research. It was found that whereas this pivotal profession is still vital in any educational system, the nature of contemporary society has necessitated a new dimension in educational psychological service delivery, namely systemic involvement. Guidelines for a new model for educational psychological learner support in the education dispensation are put forward. This model asks for the enlargement of the role of the educational psychologist to include assessment and support of all of the systems that play a role in the learner’s life.
