- Description: The integration of Information and Communication Technology (ICT) into the curriculum has become the major issue worldwide. The education system does not only pursue the integration of ICT into the curriculum because of its popularity in the market system, but because of the role it is perceived to play in the changing curriculum (encourages active construction of knowledge). According to White Paper 7 e-Education policy (2004:17) every South African learner should be able to use ICTs confidently and creatively to develop the skills and knowledge they need to achieve personal goals and to be full participants in the global community by 2013. The central role played by teachers in teaching and learning requires them to have a holistic understanding of ICT integration. Furthermore they should be able to analyse when ICT integration is appropriate according to what is expected from the learner in the teaching and learning process. Drawing on the evidence from a survey of nine secondary schools in the Grahamstown Circuit of the Eastern Cape, this study examines how teachers from three different types of secondary schools: Former Department of Education (FDET) schools, Former House of Representatives (FHOR) schools and Former Model C (FMC) schools perceive the integration of ICTs in the curriculum. The salient ideas of how teachers perceive the integration of ICTs into the curriculum emerge from what they view as benefits of using ICT and what they view as challenges of integrating ICT into the curriculum. Contrary to expectations, the degree of ICT integration within the curriculum did not correspond directly with the availability of sufficient hardware, software or Internet connectivity at the participating schools.

Changing words and worlds?: a phenomenological study of the acquisition of an academic literacy

- Description: This study is contextualised within the field of post-graduate, continuing teacher education, and the vibrant and demanding policy context that has characterised higher education in post-apartheid South Africa. Situated within a module specifically designed to address what is commonly understood to be the academic literacy development needs of students in the Bachelor of Education Honours programme at the former University of Natal, it aims to unveil the lived experiences of students taking this module. The module, Reading and Writing Academic Texts (RWAT), was developed in direct response to academics’ call that something be done about the ‘problem’ of students’ reading and writing proficiency. As a core, compulsory module, RWAT was informed by Systemic Functional Linguistics and drew on Genre Theory for its conceptual and theoretical framework. It foregrounded the genre of the academic argument as the key academic literacy that was taught. The motivation for this study came from my own increasing concern that the theoretical and conceptual framework we had adopted for the module was emerging as an inherently limiting and formulaic model of literacy, and was resulting in students exiting the module with little or no ‘critical’ perspective on any aspect of literacy as social practice. I was also keen, in a climate of increasing de-personalisation and the massification of education, to reinstate the personal. Thus, I chose to focus on individual lives, and through an exploration of a small group of participants’ ‘lived’ experiences of the RWAT module, ascertain what it is like to acquire an academic literacy. The key research question is, therefore: What is it like to acquire an academic literacy? The secondary research question is: How is this experience influenced by the mode of delivery in which it occurs? For its conceptual and theoretical framing, this study draws on social literacy theory and phenomenology, the latter as both a philosophy and a methodology. However, although the study has drawn significantly on the phenomenological tradition for inspiration and direction, it has not done so uncritically. Thus, the study engages with phenomenology-as-philosophy in great depth before turning to phenomenology-as-methodology, in order to arrive at a point where the methods and procedures applied in it, are justified. The main findings of the study suggest that, despite the RWAT module espousing an ideological model (Street, 1984) of literacy in its learning materials and readings, participants came very much closer to experiencing an autonomous model of literacy (Street, 1984). The data shows that the RWAT module was largely inadequate to the task of inducting participants into the ‘situated practices’ and ‘situated meanings’ of the Discourse of Genre Theory and/or the academy, hence the many ‘lived’ difficulties participants experienced. The data also highlights the ease with which an autonomous model of literacy can come to govern practice and student experience even when curriculum intention is underpinned by an ideological position on literacy as social practice. Finally, the study suggests that the research community in South Africa, characterised as it is by such diversity, would be enriched by more studies derived from phenomenology, and a continuing engagement with phenomenology-as-a-movement in order to both challenge and expand its existing framework.

- Description: The Tetraviridae are a family of small insect RNA viruses first discovered in South Africa some 40 years ago. They consist of one or two single-stranded (+) RNAs encapsidated in an icosahedral capsid of approximately 40 nm in diameter, with T = 4 symmetry. The type members of the two genera within this family, Nudaurelia β virus (NβV) and Nudaurelia ω virus (NωV), infect Nudaurelia cytherea capensis (pine emperor moth) larvae. The absence of N. capensis laboratory colonies and tissue culture cell lines susceptible to virus infection have limited research on the biology of NβV and NωV because the availability of infectious virus is dependent upon sporadic outbreaks in the wild N. capensis populations. In September 2002, dead and dying N. capensis larvae exhibiting symptoms similar to those reported previously in other tetravirus infections were observed in a wild population in a pine forest in the Western Cape province of South Africa. We report here the isolation of three small insect viruses from this population over a period of three years. Transmission electron microscopy and serological characterization indicate that all three are tetra-like virus isolates. One isolate was shown by cDNA sequence analysis to be NβV, which was thought to have been extinct since 1985. The two other isolates are likely new tetraviruses, designated Nudaurelia ψ virus (NψV) and Nudaurelia ζ virus (NζV), which are morphologically and serologically related to NωV and NβV, respectively.

- Description: In this study, the Jones matrix eigenanalysis (JME), optical spectrum analyzer (OSA) and polarization scrambling methods were used to investigate polarization dependent loss (PDL) in the presence of polarization mode dispersion (PMD) in optical components and fibres. The PDL measurements were conducted both in the laboratory and in the field. For field measurements, a buried link (28.8 km) and an aerial fibre (7.1 km) were extensively studied. The findings obtained from these studies are very important for network operators who must assess the impact of PDL on the network reliability. The three different PDL measurement methods (JME, OSA and polarization scrambling) were compared and their PDL values were found to agree very well at the selected wavelength of 1550 nm. Concatenation of PDL components showed that as expected, PDL increase as the number of PDL components were added. The interactions between PMD and PDL measurements were analyzed. A PMD/PDL emulator was constructed. We observed that PMD decreased while PDL increased. The PMD decrease was a result of the PMD vector cancellation enhanced by the randomly distributed mode coupling angles while PDL increase was a result of each PM fibre segments contributing to the overall global PDL. It was observed that the presence of PMD in a link containing PDL, results in PDL being wavelength dependent and this resulted in the extraction of the PMD information from the PDL data. PDL was found to be Maxwellian distributed when considering low values of PMD. High PMD values resulted in the PDL distribution deviating from Maxwellian. Long-term PDL and PMD (average DGD) measurements indicated that the PDL and PMD varied slowly with time and wavelength for both the laboratory and field measurements. It was observed that the BER increase as both PDL and PMD increased for simulated optical link.

- Description: In this study, two polarization effects, namely the state of polarization (SOP) and polarization mode dispersion (PMD) in optical fibre cable are investigated. The change in polarization effects introduces errors in optical fibre communication system. We find that the SOP drifts slowly in buried cables, and rapidly in aerial cables. This is because buried cables are located in a static environment, whereas aerial cables are exposed directly to a dynamic environment. The SOP change in aerial cable shows significant correlation with its environment (the global radiation, temperature and wind). The autocorrelation function (ACF) was not performed in buried cable, since they do not satisfy the ACF assumption, whereas in aerial cable it is found that the ACF of the SOP decorrelates quite quickly during the day. The 50 percent decorrelation time during the day and night are 9.6 and 30.4 minutes, respectively. During the day the properties of the optical fibre change rapidly as a result of the rapidly changing environmental conditions, whereas at night the environmental conditions change relatively slowly. Fast Fourier Transform (FFT) of the SOP fluctuations show discrete peaks, which corresponds to the wind induced vibrational frequency of the cable. The PMD fluctuations for undeployed and deployed aerial optical fibre cable are monitored using the generalized interferometric technique (GINTY). It is found that the PMD measured with polarization scrambling is more scattered but more reliable than the PMD measured without polarization scrambling. This is because the PMD obtained with polarization scrambling is averaged over different input and output (I/O) SOP pairs. For deployed aerial cable, it is found that the PMD measured without polarization scrambling fluctuates rapidly during high wind speed conditions. Furthermore, there is a correlation between the measured PMD and the change in temperature. It is found that the change in temperature has a stronger influence than the wind on the PMD of the optical fibre link.

- Description: The School Clustering System (SCS) was introduced five years after Namibia’s independence in 1990. The rationale for its implementation was to improve the quality of education in Namibian schools by enabling the sharing of resources, experience and expertise among clusters and facilitating school administration by pooling resources from several schools to be shared equally. It was piloted in Rundu and then gradually expanded to the whole country. The cluster system groups 5-7 schools that are eographically close and accessible to each other in one cluster under the leadership of one of the principals known as a Cluster Centre Principal (CCP). The purpose of this study was to investigate the perceptions of CCPs of the implementation of the SCS in two clusters of a particular circuit in the Omusati region. It is a case study involving two CCPs, one serving Inspector of Education (IE), a former Inspector of Education, several teachers, principals and parents. Data were collected through interviews, document analysis, and focus group discussions. The study found that the practice of cluster leaders is informed by contemporary leadership and management thinking. The participatory approach employed in clusterbased committees enables site-based management and collaboration. This has led to organisational learning. It was also found that a number of challenges are hampering the implementation of the SCS. These include lack of system support and inadequate resources. However, the human potential coupled with a high degree of readiness exhibited by cluster members are seen as potential drivers of further development of the system. The study recommends the adoption of a national policy that formalises the SCS as well as the strengthening of system support to build cluster capacity. It also makes suggestions for further research in organisational culture and behaviour with the aim of developing leadership and management practices in the SCS.

- Description: Understanding population connectivity is fundamental to ecology, and, for sedentary organisms, connectivity is achieved through larval dispersal. We tested whether coastal topography influences genetic structure in Perna perna mussels by comparing populations inside bays and on the open coast. Higher hydrodynamic stress on the open coast produces higher mortality and thus genetic turnover. Populations on the open coast had fewer private haplotypes and less genetic endemism than those inside bays. Gene flow analysis showed that bays act as source populations, with greater migration rates out of bays than into them. Differences in genetic structure on scales of 10s of kilometres show that coastal configuration strongly affects selection, larval dispersal and haplotype diversity.

Between 1967 and 1994 approximately 300 000 young white males were conscripted by the SADF. As far as most of these conscripts were concerned, there was no option other than heeding the call-up and performing national service or diensplig. Failure to do so meant harsh penalties. The alternatives were to object on conscientious (actually religious) grounds and face a six year jail sentence, or flee the country. And the obligation did not end with national service as conscripts were assigned to citizen force or commando units that were liable for periodical call-ups for camps that might have included deployment in the “operational areas” from 1974 or tours of duty in the black townships from 1984. Those - like myself - belonging to this national service generation were part-time soldiers for much of their adult lives. Most served willingly, some with patriotic fervour. Others did so reluctantly and with little enthusiasm.

Those - like myself - belonging to this national service generation were part-time soldiers for much of their adult lives. Most served willingly, some with patriotic fervour. Others did so reluctantly and with little enthusiasm.

- Description: This thesis seeks to trace domination theory back to the influential work done by Marx on commodity fetishism. Marx's work proves to be an original account of domination that explains how the dominated many accept the rule of the privileged few. The theory of commodity fetishism develops the idea that individuals come to adopt beliefs that bolster and reproduce the status quo of capitalism. For Marx, the way that individuals experience capitalism is different from the way that it actually works because, in fact, lived experience is actually false. Oppression, inequality and exploitation are thus hidden and the main source of conflict between the oppressed many and the privileged few is obscured. I seek to develop this insight of Marx's into a more comprehensive account of how dominating capitalism self maintains. Lukács' theory of reification explains how capitalism has become all-embracing because capitalism has developed its own type of rationality. This specific rationality shapes thought, which in turn, generates false beliefs that favour the continuation of the status quo. Horkheimer and Adorno argue that capitalism extends its influence by means of its deep involvement in modern culture. Today, culture has become an massive industry which inculcates the logic and principles of capitalism into individuals. For these theorists, capitalism has penetrated all areas of life; experience, knowledge and thought have become extensions of capitalism itself. Marx, Lukács, Horkheimer and Adorno give accounts of how false beliefs are put into practice. Hence the importance of the work of Bourdieu. Bourdieu's theory of distinction describes how the status quo in capitalism is maintained by the behaviour of individuals through their daily acts of consumption. I argue that the consumption of commodities reproduces the status quo in two ways: firstly, establishing an upper-class which takes the lead in patterns of consumption, and, secondly, by creating a middle class that follows its example. Finally, I relate Bourdieu's insights to the theories of Marx, Lukács, Horkheimer and Adorno and Bourdieu in order to arrive at a more inclusive account of how.

- Description: Goats significantly contribute towards the subsistence, economic and social livelihoods of many resource-poor farmers in developing countries, the majority of which own goats. There, however, is dearth of information on communal goat production potential and roles to the rural populace. The broad objective of the study was to evaluate production practices, constraints, production efficiency and to determine nutritional and health status of goats raised by resource-poor communal farmers in the Eastern Cape Province of South Africa. Roles and management systems of goats, goat flock dynamics and, prevalence and loads of gastrointestinal infections and the nutritional status of goats in the study areas were determined. The relationships among body weight, body condition score, faecal egg counts and, haematological and biochemical profiles were also determined. Mean goat flock sizes per household were similar between the two districts studied; Amatole (14.0 ± 0.31) and Alfred Nzo (14.1 ± 1.42). Seventy-nine percent of households in Amatole and 78% in Alfred Nzo kept goats for ceremonies, such as the initiation ceremonies. Goat houses in the two districts were poorly constructed. Thirty two percent of farmers in Alfred Nzo district and 27% in Amatole district reported low buck to doe ratios, suggesting that inbreeding might have been reducing productivity of their flocks. Kid mortality had two major peaks; in May (21%) and in September (21%). Goat production potential (GPP), the proportion of mature and growing goats to the total flock size, was affected by gender of owner of goats. Goats owned by female had a significantly lower GPP value of 0.63 ± 0.015 than goats owned by male farmers (0.70 ± 0.010). Month also significantly affected GPP with the highest (P < 0.05) GPP recorded in May, June and July and the lowest in March and April. Village affected GPP with values for Nkosana and Qawukeni being significantly higher than for Mankone. Goat production potential was also higher (P < 0.05) in small flocks (0.04 ± 0.008) than in large flocks (0.02 ± 0.008). Goat production efficiency (GPE) ranged from 0.11 ± 0.193 in April to 1.55 ± 0.193 in December. The most prevalent gastrointestinal eggs were the strongyle egg type (68.4 ± 8.49 in Qawukeni and 96.1 ± 12.01 in Nkosana) followed by coccidia (53.3 ± 8.76 in Qawukeni and 68.8 ± 8.00 in Mankone). The other identified nematodes were Strongyloides and Trichostrongylus egg types. The trematodes observed were Fasciola and Paramphistomum species. High loads of strongyle eggs were observed in the hot-wet season and the post-rainy season, whilst the other egg types showed a peak in the hot-wet season only. For most of the gastrointestinal parasite eggs, prevalence was higher (P < 0.05) in the sour rangeland compared to the sweet rangeland. Higher (P < 0.05) levels of total protein (TP), globulin, aspartate aminotransferase (AST) and creatinine kinase (CK) levels were recorded in the wet than in the dry season. Body condition scores were positively correlated (P < 0.05) to albumin, body weight and packed cell volume. However, body condition scores were negatively correlated to TP, glucose, alanine transaminase (ALT) and AST. Strongyle egg loads were positively correlated to FAMACHA scores, packed cell volume, body weight and body condition score. The observed high globulin levels suggested a chronic health challenge. Thus, it is fundamental to devise affordable interventions for the control of gastrointestinal parasites in communal goats leading to improved goat productivity and hence rural livelihood

- Description: Language rights in South Africa are entrenched in the Constitution of South Africa (Chapter 1, Section 6, Constitution of the Republic of South Africa, 1996). However, the concomitant infrastructure and organisational realities make this policy difficult to implement, especially in law courts (Kaschula and Ralarala 2004). Creating effective communicative environments has historically been constrained by lack of effective training of legal practitioners and by the lack of capacity for building translation structures. With the advancement of technology, potential solutions are becoming more apparent and it is incumbent upon the academic community to embark on a rigorous investigation into possible solutions and how these Information Communication Technology (ICT) solutions could be applied to the execution of justice in South African law courts. This article aims to open the discourse of possible solutions, via assessments of computer based translation solutions, ICT context simulations and other potential opportunities. The authors hope to initiate the interest of other language and legal practitioners to explore how the new technological capabilities could be harnessed to support the entrenchment of language rights in our law courts.

- Description: This study focused on community development education and practice for the democratic and transformative South context. Social and community development are relatively new approaches to social welfare and community development is emerging as a discipline and profession to contribute to the goal of developmental social welfare. Community work, albeit to a minimal extent and not community development was viewed as a method of social work during apartheid. With community development being prioritized as an intervention strategy for poverty reduction by the national government, the gap in community development education needs to be addressed. The goal of the study was to develop an undergraduate curriculum framework for community development education that would produce a new generation of ethical community development professionals to contribute to the goal of developmental social welfare. The study focused on the integrated approach to community development education and practice; with education of the student as a whole human being as critical for community development in a transformative South Africa. To achieve its goal, the study identified three themes that were critical to the research: a conceptual framework, clarifying key terms; a curriculum framework for community development education; and qualities and ethics for a new generation of development practitioners. The qualitative study was based in the Eastern Cape Province, South Africa and because of the lack of a referential framework for community development education, the researcher looked towards learning from India which has over fifty years of experience in social and community development education and practice. The state of Kerala established a social development approach in 1957 and was chosen as a learning experience. The state’s Kudumbashree Mission which aims at poverty alleviation through the empowerment of women was chosen as a case study. The integral and values based education system of Sri Sathya Sai University in the state of Andhra Pradesh and the community development education and practice of Loyola College in the state of Kerala were examined. The research design was exploratory, conceptual, descriptive and developmental in nature. The qualitative methodology best suited the nature of this study and a combination of methods to obtain data from a variety of sources across national boundaries was employed. The participants interviewed in both countries were purposively selected for their involvement in social and community development directly as target groups, practitioners, managers and policy makers. The research produced a philosophical and theoretical framework that is unitary and integral and aligned with the current social development policy to guide community development education and practice. The unitary and integral framework encompasses the individual within the family and community context and locates the various dimensions of development such as the social, physical, cultural, psychological, spiritual, political and economical dimensions within a unitary platform. The framework is dominated by the holistic and humanistic philosophies without negating the rational and pragmatic perspectives. In conclusion, the study conceptualizes community development as a natural process; the integration of individual and collective consciousness and an intervention. The outcome of the study is a recommended curriculum framework for community development education that would be of relevance to the Eastern Cape Province in particular and for the South African context generally.

- Description: Development thinkers and practitioners have been pondering over community participation for the last decades. Some even called the 1980s a decade of participation in development discourse while others also view the current decade of social movements, Non-Governmental Organizations, and Community-Based Organizations as a manifestation of organized community participation. The Sangwe Communal Lands is one such area that researchers in the last decades have been pondering over the role of community participation in project sustainability. Likewise this study evaluates the effectiveness of community participation in Sangwe where it has been hypothesized that the current participation discourse has not lived up to its billing of ensuring sustainable projects. The research therefore explores some of the politics surrounding community participation in Sangwe and Zimbabwe at large. From one angle to the other, the research overviews some of the different theoretical orientations, goals, processes and practices that are commonly used but not always recognized to constitute genuine community participation. The research is intended to clarify some of the differences that emerge when projects are designed, and to stimulate discussion about community participation more generally. This study shows that the local communities who in this case are the reason for being of NGOs and their programmes are quite critical in development projects undertaken in their own areas. This to a larger extent determines the success of development initiatives at all levels. Such a scenario calls for a proper sustainable and pro-rural community legal and policy framework as a pre-requisite for sustainable projects. The study further highlights the need for development workers and agents to change their attitude towards communities and their indigenous knowledge systems. They need to co-opt community indigenous knowledge as a system that has a unique contribution to sustainable development. Above all, attitude change is the pillar for the New World System and 21st century development paradigm that respects local values, concerns, culture, and aspirations and that these should be taken on board in the management of development programmes.

- Description: This study evaluates the potential for community-based ecotourism as conservation and development strategy in Kome village, which is an unprotected area. The study adopts the ecotourism concept to illustrate how communitybased ecotourism can be a tool for conservation and development in poor rural communities. Adopting the intensive case study design, the study investigates the major challenges for community-based ecotourism in Kome village. Findings reveal that Kome community derives low socio-economic benefits including limited earnings, low employment, poor benefits sharing and lack of entrepreneurships. Kome has a potential to offer better community-based ecotourism products due to diverse tourist attractions ranging from historical, cultural activities to natural scenery. The study suggests and recommends formation of a partnership between the Kome community, private, public sector and the NGOs as a strategy for development. The study concludes that ecotourism can be an appropriate option for conservation and development for Kome village.

- Description: This study aims to ascertain the legal redress available to employees who suffer psychological harm as a result of workplace stress. On a general level, it identifies and assesses some of the available policy options, particularly as they relate to the interaction of statutory workers’ compensation schemes and the common law. On a more specific level, it examines and analyses various issues: the nature and extent of compensable psychiatric harm; the legal duty on employers to protect employees’ health and well being; the role of negligence; requirements specific to the Compensation for Occupational Injuries and Diseases Act 130 of 1993 (COIDA); and the causal nexus necessary to sustain a claim. The conclusion is reached that employees should utilise the workers’ compensation system as the primary vehicle to obtain redress if they suffer from occupational psychiatric harm. However, due to the law’s generally conservative approach to psychiatric harm and intimations that the Department of Labour intends setting strict requirements for claims for psychiatric harm in terms of COIDA, the common law of delict might continue to play an important role in claims for occupational psychiatric harm. The writer recommends that a hybrid system for compensation for stress-related psychiatric harm suffered in the course and scope of employment be adopted, with the statutory compensation scheme providing relatively limited benefits and the common law providing general damages if the claimant can prove negligence on the part of the employer; that the requirement of a recognised psychiatric illness be maintained for both statutory compensation and compensation in terms of the common law; that all parties’ interests are carefully balanced in delineating the employer’s legal duty to employers and that undue weight not be accorded to the terms of the contract of employment; that more attention be paid to factual causation and the development of lternatives/complements to the traditional conditio sine qua non test; that the validity of the circular instruction on post-traumatic stress disorder (PTSD) be tested on administrative-law grounds; and that the stringent prescription requirements set by the circular instruction on PTSD be reviewed.

- Description: This study aims to ascertain the legal redress available to employees who suffer psychological harm as a result of workplace stress. On a general level, it identifies and assesses some of the available policy options, particularly as they relate to the interaction of statutory workers’ compensation schemes and the common law. On a more specific level, it examines and analyses various issues: the nature and extent of compensable psychiatric harm; the legal duty on employers to protect employees’ health and well being; the role of negligence; requirements specific to the Compensation for Occupational Injuries and Diseases Act 130 of 1993 (COIDA); and the causal nexus necessary to sustain a claim. The conclusion is reached that employees should utilise the workers’ compensation system as the primary vehicle to obtain redress if they suffer from occupational psychiatric harm. However, due to the law’s generally conservative approach to psychiatric harm and intimations that the Department of Labour intends setting strict requirements for claims for psychiatric harm in terms of COIDA, the common law of delict might continue to play an important role in claims for occupational psychiatric harm.

- Description: Capsicum baccatum var. pendulum was first grown in the Makana District in 2005. Extremely little was known about best practices for cultivation or the insects and diseases associated with the crop in this area. The study was conducted during the second year of production, November 2005 and November 2006, in an attempt to identify the composition and phenology of insects occurring on C. baccatum. In the more rural parts of the Eastern Cape, and more particularly in Grahamstown, there are very few industries. With the advent of this new agricultural venture, a processing factory has been opened in Grahamstown creating more than 600 seasonal jobs in the factory and 1000 seasonal jobs on farms for local people. This business enterprise has not only brought about the creation of jobs, but also training and skills development and empowerment, generating much-needed income in this area. An extensive literature review yielded limited information on insect pests associated with Capsicum. Data from a pilot sampling trial undertaken were statistically analyzed to establish the number of plants to be scouted per site and the most effective scouting techniques to use. Based on the data available and insects collected during the pilot sampling trial, a surveillance programme was designed. Five different types of monitoring traps were placed in each of the eight study sites. Collection of trap catches and scouting of fifteen individual plants per site was undertaken on a weekly basis over the 52-week study period. The most commonly occurring potential insect pests were African Bollworm Helicoverpa armigera (Hübner), False Codling Moth Thaumatotibia leucotreta (= Cryptophlebia leucotreta) (Meyrick), Mediterranean Fruit Fly Ceratitis capitata (Wiedemann) and several species of thrips. Population densities of these pests and their phenology on Capsicum were determined. Statistical analyses established the efficacy of the monitoring traps for each pest, tested for differences among and between study sites, calculated an estimate of the number of pods damaged and a measure of plant damage.The results show that the majority of damage caused to the Capsicum baccatum cropping system was due to Mediterranean Fruit Fly populations. It was established that, although African Bollworm and False Codling Moth were present during the study period, their numbers were negligible and only nominal damage was caused by these pests. Damage caused by thrips species was apparent but not quantifiable. Intervention strategies using an Integrated Pest Management approach, are discussed.

- Description: Community radio typically relies on volunteers to produce and present stations’ programming. Volunteers are generally drawn from stations’ target communities and are seen as “representatives” of those communities. It is with such volunteers and their role as representatives of stations’ target communities that this study is concerned. It poses the question: “what are the central concepts that typically inform volunteers’ knowledge of their target community, and how do these concepts impact on their perception of how they have gained this knowledge, and how they justify their role as representatives of this community?” The dissertation teases out the implications of these conceptualisations for a volunteer team’s ability to contribute to the establishment of a media environment that operates as a Habermasian ‘critical public sphere’. It argues that this can only be achieved if volunteers have detailed and in-depth knowledge of their target community. In order to acquire this knowledge, volunteers should make use of systematic ways of learning about the community, rather than relying solely on knowledge obtained by living there. In a case study of Katutura Community Radio (KCR), one of the bestknown community radio stations in Namibia, the study identifies key differences in the way in which different groups of volunteers conceptualise “the community”. The study focuses, in particular, on such difference as it applies to those who are volunteers in their personal capacity and those who represent non-governmental and community-based organisations at the station. It is argued that two strategies would lead to significant improvement in such a station’s ability to serve as a public sphere. Firstly, the station would benefit from an approach in which different sections of the volunteer team share knowledge of the target community with each other. Secondly, volunteers should undertake further systematic research into their target community. It is also argued that in order to facilitate such processes, radio stations such as KCR should recognise the inevitability of differences between different versions of “community knowledge”.

- Description: The Prevention of Organised Crime Act brought major changes to the South African criminal law context. Through the Act, major confiscatory provisions were established. The Act does not only target convicted criminals, but also any person who is in possession of tainted property that was used in the commission of offences. Civil forfeiture is the most widely used procedure in forfeiture proceedings. In the dissertation the effectiveness of criminal and civil confiscation is outlined. The historical development of confiscation and forfeiture provisions in South African is discussed with reference to the common law, legislation and international instruments and how international developments have influenced local development. This treatise consist of an overview of the confiscation provisions in the Prevention of Organised Act 121 of 1998 as one of the measures the South African legislature put in place to deal with organised crime. Since the Prevention of Organised Crime Act was passed, the courts have given meaning to what is an instrumentality of an offence and the proceeds of unlawful activities as a measure to counter organised crime. This treatise refers to those cases given the definition of an instrumentality of an offence and the proceeds of unlawful activities. For the purpose of effectively dealing with organised crime, this treatise contains a discussion on the effectiveness of criminal and civil confiscation procedure. The justification for asset forfeiture is outlined.

- Description: Traditionally, connection management applications (referred to as patchbays) for high-speed audio networking, are predominantly developed using third-generation languages such as C, C# and C++. Due to the rapid increase in distributed audio/video network usage in the world today, connection management applications that control signal routing over these networks have also evolved in complexity to accommodate more functionality. As the result, high-speed audio networking application developers require a tool that will enable them to develop complex connection management applications easily and within the shortest possible time. In addition, this tool should provide them with the reliability and flexibility required to develop applications controlling signal routing in networks carrying real-time data. High-speed audio networks are used for various purposes that include audio/video production and broadcasting. This investigation evaluates the possibility of using Adobe Flash Professional 8, using ActionScript 2.0, for developing connection management applications. Three patchbays, namely the Broadcast patchbay, the Project studio patchbay, and the Hospitality/Convention Centre patchbay were developed and tested for connection management in three sound installation networks, namely the Broadcast network, the Project studio network, and the Hospitality/Convention Centre network. Findings indicate that complex connection management applications can effectively be implemented using the Adobe Flash IDE and ActionScript 2.0.
