- Description: This dissertation argues that in the 1990s and beyond, the character and functions of regions and regionalism have experienced a major transformation. This requires a reconceptualisation of regions and regionalism that transcends state-centrism. The argument here is that the definition of regions and regionalism needs to recognise that other actors also participate in the construction of regions and the practise of regionalism. Up to now, however, theories of integration incompletely deal with outcomes appropriate to developing countries, states and regions. In the context where people remain vulnerable to top-down forms of regionalism driven by the forces of globalisation, this calls for a new approach in the analytical study of regionalism in a transnational context. The contention is that new regionalism, and its variant, developmental regionalism pay attention to the role those organised civil society actors and those marginalised by both globalisation and regionalisation play in promoting regionalism in a transnational context. Historically, state-centric regionalism in southern Africa was not aimed at achieving developmental objectives. In the case of SACU, the argument is that South Africa used its economic strength in a hegemonial way. To counter-act apartheid South Africa’s economic hegemony, SADCC was formed. SADCC achieved limited success in the fields of infrastructural development and in attracting donor aid. The end of the Cold War and the downfall of apartheid compelled these organisations to recast their objectives and purpose. For SACU this meant changing from an organisation dominated by South Africa to a fully-fledged inter-state one. Disconcertedly, however, about the reforms undertook by SACU, is that the disposition of member states remain important in determining the content and scope of regionalism. SADC, on the other hand, has also not sufficiently reform itself to achieve the ambitious goals it set-out for itself. Moreover, while SADC has since its inception in 1992 set-out to involve non-state actors in its regional integration efforts, limited institutional reform in 2000 and beyond, and elites at the forefront of institutional restructuring make it difficult for non-state actors to contribute to sustainable regional integration. In conclusion, this dissertation maintains that sustainable regionalist orders are best built by recognising that beyond the geometry of state-sovereignty, civil society organisations with a regional focus and the ordinary people of the region also contribute to regioness and as such to the re-conceptualisation of regional community in southern Africa.

- Description: This thesis examines Seamus Heaney’s approach to translation with specific reference to Sweeney Astray, The Cure at Troy, and Beowulf. An assessment of Heaney’s translations, and the ways in which they relate to his poetry, is essential to an understanding of his work as a poet. This thesis demonstrates the centrality of translation to Heaney’s oeuvre as an effective means to comment on his Northern Irish socio-political context without producing political propaganda. Translation is a valuable means for Heaney to elucidate his contemporary experience by considering it in terms of the recorded past captured within his chosen translations. Instead of comparing the three translations with their original texts, this thesis concentrates on Heaney’s translations as a continuation of his own creative work and as catalysts for further poetry. The translations are explored in chronological order to allow a sense of Heaney’s development as a translator and his efforts to remain critically attuned to the Northern Irish political situation. The first chapter examines Heaney’s translation of the Gaelic poem Buile Suibhne, which is published as Sweeney Astray. In this first major act of translation Heaney recognises the political role that translation is able to play. He draws attention to the protagonist’s sense of cultural ease in both Britain and Ireland, which he argues is exemplary for the people of Ulster and renders the narrative particularly accessible to a Northern Irish readership due to his anglicisation of the text, which is intended as a reminder to both Catholics and Protestants of their shared identity as Irishmen. The second chapter focuses on Heaney’s translation of Sophocles’ Philoctetes, entitled The Cure at Troy. Heaney’s translation contextualises the Ancient Greek concern for personal integrity in the face of political necessity, a situation relevant to his own complex relationship with Northern Irish politics. His alterations to the text accentuate the positive aspects of the play, suggesting the very real possibility of social change within the seemingly constant violence of Northern Ireland. The third chapter explores Heaney’s engagement with the Anglo-Saxon epic poem, Beowulf, as a means of coming to terms with the complex history of Irish colonisation through language. This chapter assesses Heaney’s incorporation of Irish dialectal words into his translation, which lend the poem political weight, and yet prove to be contextually appropriate, rendering Heaney’s Beowulf a masterpiece of readability and subtle political commentary.

- Description: Experiences in treating wine distillery wastewaters (WDWs) contribute to the field of oenology as many oenologists are concerned with the selection, efficiency and economy of their wastewaters. Wine distillery wastewaters are strongly acidic, have high chemical oxygen demand (COD), high polyphenol content and are highly variable. Primary attention was focussed on sustainable biological treatment of raw wine distillery wastewater (RWDW) and fungally pre-treated wine distillery wastewater (FTWDW) by energy-efficient high rate anaerobic digestion (AD). This study also explored the development of a novel dual-stage anaerobic digestion ultrafiltration (ADUF) process, using a ceramic submerged membrane bioreactor (SMBR) in the treatment of both RWDW and FTWDW. The first stage was for the selection of microorganisms that were able to treat the toxic pollutants from WDWs. It was operated at a high feed-to-microorganism ratio. The second stage, a secondary digester, was operated like a typical membrane bioreactor at a low feed-to-microorganism ratio to sustain a stable efficient population for a long period. The characteristics of RWDW were as follows: pH 3.83, 15 000 mg/l soluble COD (CODs) and 5229 mg/l of phenols. After pre-treatment of RWDW with Trametes pubescens, starting parameters for FTWDW were as follows: pH 6.7, 7000 mg/l soluble COD (CODS) and 1440 mg/l of phenols. During operation of a high rate anaerobic digester for RWDW treatment, K2HPO4 was required for buffering the digester. Volatile fatty acid concentrations were <300 mg/l throughout the study, indicating degradation of organic acids present. Mean CODS removal efficiency for the 130 day study was 87 %, while the mean polyphenol removal efficiency was 85 %. Addition of 50 mg/l Fe3+ increased the removal efficiencies of CODS to 97 % and of polyphenols to 99 %. High removal efficiencies of CODS and polyphenols were attributed to the addition of macronutrients and micronutrients that caused pH stability and stimulated microbial activity. The CODS removal efficiency of high rate anaerobic digestion of FTWDW reached 99.5%. During FTWDW digestion, pH buffering was achieved using K2HPO4. A combination of a SMBR and a secondary digester was tested for the treatment of RWDW and FTWDW during a 30 day study. Results for RWDW showed that pH buffering was achieved by dosing the feed stream with CaCO3 and K2HPO4. Buffering proved to be significant for optimum performance of the system in removal of soluble CODS, and volatile fatty acids (VFAs). Different batches of RWDW used for feeding the reactor had variable compositions with respect to concentrations of nitrates, ammonium and total phenolic compounds. Ammonium accumulated in the secondary digester after 14 days of system operation, indicated the time required for the establishment of anaerobic conditions in the system. Dosing of the SMBR treating FTWDW with CaCO3 and K2HPO4 buffered the pH; iii this proved significant for optimum performance of the system in removal of CODS. The system eliminated an average of 86 (± 4) % of CODS present in the FTWDW. The residual CODS levels in the effluent were approximately 400 mg/l, significantly lower than the concentrations observed when treating RWDW, indicating that fungal pre-treatment might have provided additional nutrients for removal of recalcitrant components of the wastewater. The resulting effluent was rich in nitrates and phosphates and might be used as a fertiliser. Alternatively, a membrane process, such as reverse osmosis (RO) or nanofiltration (NF) could be applied to raise the water quality to meet the levels required for reuse. Biomass samples were obtained from the four treatment systems and population shifts characterization using phospholipids fatty acids (PLFA) and 16S rRNA analysis to provide an indication of limitations within the microbial population. The values of the concentrations of the individual PLFAs detected in the samples indicated that ten bacterial species were present, with the GC content of the 16S rRNA increasing from 1 to 10. Analysis of denaturing gradient gel electrophoresis DGGE data indicated that the composition of the archeal community changed the consortia used for both RWDW and FTWDW treatment. Changes in band intensities indicated the presence of different components of the archeal communities. The results were not conclusive in terms of species identity as cloning, sequencing and phylogenetic analyses were not performed, but they did indicate microbial population shifts and species diversity for high rate anaerobic digestion. The results also confirmed prevalence of relatively few species during operation of SMBRs for treatment of RWDW and FTWDW, which suggested that the microorganisms that survived were either tolerant of toxic components of RWDW and FTWDW or they were able to remove polyphenols.

- Description: Long-term interannual changes in richness, abundance, diversity and structure of the fish community in the temporarily open/closed East Kleinemonde Estuary, Eastern Cape, are described and the recruitment success of two estuary-dependent marine species assessed. In addition, laboratory experiments were conducted to assess the possible role of olfaction in the recruitment process of an estuary-dependent marine fish species. Multivariate analyses of the annual marine fish communites identified two distinct groups with more species recorded during years that succeeded spring (September to November) mouth opening events than in years following no mouth opening events in spring. Interannual community stability (IMD) and seriation (IMS) also increased from the ‘other’ to the ‘spring’ years. These results highlight the importance of the timing of mouth opening to the marine fish community in a temporarily open/closed estuary. This study also made use of long-term records of daily mouth state and linked them to the recruitment of distinct year-class cohorts in two spardis with contrasting lifehistory characteristics. Lithognathus lithognathus only recruited into the estuary in years when the mouth opened between late August and January. This was linked to the limited spawning season of this species and its inability to enter closed estuaries via wave overwash events. In contrast, recruitment by Rhabdosargus holubi juveniles appeared to be uninterrupted and was not determined by the seasonality of mouth opening. This species dominates the marine-spawning component of the East Kleinemonde Estuary and its success is attributed to an extended spawning season and its ability to recruit into estuaries during both overwash and open mouth conditions. Attraction of postflexion Rhabdosargus holubi larvae to estuary, surf zone and river water was also measured using a rectangular choice chamber. In two sets of experiments, conducted during peak recruitment periods, larvae from both the surf zone and estuary mouth region selected estuary water with a significantly higher frequency than sea water. Larvae collected in the mouth region showed a stronger preference for river water than those collected in the surf zone, thus suggesting that these fish are more attracted to freshwater influenced nursery areas once they have entered the estuary than those in the surf zone. Larvae collected in the marine environment also selected surf zone water with significantly higher frequencies than estuary water or offshore sea water, thus confirming the importance of the surf zone as an interim nursery area for postflexion R. holubi.

- Description: The Semantic Web is a vision to create a “web of knowledge”; an extension of the Web as we know it which will create an information space which will be usable by machines in very rich ways. The technologies which make up the Semantic Web allow machines to reason across information gathered from the Web, presenting only relevant results and inferences to the user. Users of the Web in its current form assess the credibility of the information they gather in a number of different ways. If processing happens without the user being able to check the source and credibility of each piece of information used in the processing, the user must be able to trust that the machine has used trustworthy information at each step of the processing. The machine should therefore be able to automatically assess the credibility of each piece of information it gathers from the Web. A case study on advanced checks for website credibility is presented, and the site presented in the case presented is found to be credible, despite failing many of the checks which are presented. A website with a backend based on RDF technologies is constructed. A better understanding of RDF technologies and good knowledge of the RAP and Redland RDF application frameworks is gained. The second aim of constructing the website was to gather information to be used for testing various trust metrics. The website did not gain widespread support, and therefore not enough data was gathered for this. Techniques for presenting RDF data to users were also developed during website development, and these are discussed. Experiences in gathering RDF data are presented next. A scutter was successfully developed, and the data smushed to create a database where uniquely identifiable objects were linked, even where gathered from different sources. Finally, the use of digital signature as a means of linking an author and content produced by that author is presented. RDF/XML canonicalisation is discussed in the provision of ideal cryptographic checking of RDF graphs, rather than simply checking at the document level. The notion of canonicalisation on the semantic, structural and syntactic levels is proposed. A combination of an existing canonicalisation algorithm and a restricted RDF/XML dialect is presented as a solution to the RDF/XML canonicalisation problem. We conclude that a trusted Semantic Web is possible, with buy in from publishing and consuming parties.

- Description: The last couple of decades saw lots of changes in the business world. Not only did technology change at a rapid pace, but businesses' views with respect to the role that information plays also changed drastically. Information is now seen as a strategic resource. This change paved the way for the so-called knowledge worker that not only consumes information, but actively participates in creating new knowledge from information. Employees must therefore be empowered to fulfill their new role as knowledge workers. Empowerment happens through job redefinition and by ensuring that the appropriate information is at hand. Although information is more readily available to employees, appropriate access controls must still be implemented. However, there is conflict between the need to share information and the need to keep information confidential. These conflicting needs must be reflected in the administration of access control. In order to resolve these conflicts, a finer granularity of access controls must be implemented. However, to implement a finer granularity of access control, an increase in the number of access controls and, therefore, the administrative burden is inevitable. Access control administrators must cater for a potentially large number of systems. These systems can not only be heterogenous as far as architecture and technology are concerned, but also with respect to access control paradigms. Vendors have realized that human involvement must be minimized, giving birth to so-called "provisioning systems". Provisioning systems, in principle, automate certain parts of access control administration. However, currently implementations are done in an ad hoc manner, that is, without a systematic process of identifying the real access control needs. This study aims to address this problem by proposing the "agreement abstraction" as a possible vehicle for systematically analyzing the access control requirements in a business. In essence, the agreement abstraction allows us to identify opportunities where access control can be automated. A specific methodological approach is suggested whereby the business is analysed in terms of business processes, as opposed to the more traditional resource perspective. Various business processes are used as examples to explain and motivate the proposed agreement abstraction further. This dissertation therefore contributes to the field of discourse by presenting a new abstraction that can be used systematically to analyse access control administration requirements.

- Description: The last couple of decades saw lots of changes in the business world. Not only did technology change at a rapid pace, but businesses' views with respect to the role that information plays also changed drastically. Information is now seen as a strategic resource. This change paved the way for the so-called knowledge worker that not only consumes information, but actively participates in creating new knowledge from information. Employees must therefore be empowered to fulfill their new role as knowledge workers. Empowerment happens through job redefinition and by ensuring that the appropriate information is at hand. Although information is more readily available to employees, appropriate access controls must still be implemented. However, there is conflict between the need to share information and the need to keep information confidential. These conflicting needs must be reflected in the administration of access control. In order to resolve these conflicts, a finer granularity of access controls must be implemented. However, to implement a finer granularity of access control, an increase in the number of access controls and, therefore, the administrative burden is inevitable. Access control administrators must cater for a potentially large number of systems. These systems can not only be heterogenous as far as architecture and technology are concerned, but also with respect to access control paradigms. Vendors have realized that human involvement must be minimized, giving birth to so-called "provisioning systems". Provisioning systems, in principle, automate certain parts of access control administration. However, currently implementations are done in an ad hoc manner, that is, without a systematic process of identifying the real access control needs.

- Description: There are about 259 estuaries in South Africa that can be classified as “functioning” and their “health” status is directly related to the quantity and quality of freshwater that flows into them. Many of South Africa’s estuaries have become smaller due to a steady decrease in the amount of freshwater that flows into them. This reduction in freshwater inflows decreases their ecological functioning and undermines the recreational activities and subsistence services available from them. The National Water Act (ACT No. 36 of 1998) recognises the right of the environment to water, but a large amount of data is still needed to make management decisions on the allocation of freshwater. The objective of this research was to contribute to the management of the allocation of freshwater in the catchment areas of the Bira, Bushmans, Kasouga, Keiskamma, Kleinemond East, Nahoon and Tyolomnqa rivers by determining the recreational value of the freshwater flowing into their estuaries. This recreational value was established using the contingent valuation method. The contingent valuation method (CVM) is a technique to establish the value of a good (or service) that is not bought or sold in an actual market. This technique is frequently applied in the valuation of environmental goods, e.g. the freshwater that flows into an estuary. The CVM establishes the economic value by asking the users of an environmental good to state their willingness to pay (WTP) for a hypothetical project to prevent or bring about a change in the current condition of the environmental good. The users’ WTP is then aggregated to establish a total willingness to pay (TWTP) for the population of the users of the environmental good. The hypothetical project presented in this study is that of an increase of freshwater inflows, that would prevent (bring about) predetermined changes in environmental services provided by the selected seven estuaries.

- Description: Sexual harassment is an ever increasing drain on the resources of the modern employer, as well as serving to take up much time in terms of legal battles and court cases. The concept of sexual harassment has undergone much revision over the past decades, and South Africa is now firmly committed to the eradication of this problem. The Constitution protects and enshrines important rights like dignity, equality and the right to fair labour practices. These are further defined and protected through the application of various statutes, including the LRA, EEA, PEPUDA and the revised Code of Good Practice. In terms of statutory liability, the employer will be liable for the harassment of its employees, unless it takes a proactive stance and implements comprehensive sexual harassment policies. In this way it will escape liability. The common law vicarious liability of the employer cannot be escaped as easily. The entire concept of the law of delict is to remedy harm suffered. In terms of the common law, employers will be held vicariously liable for the harassment of their employees if it can be shown that the harassment occurred within a valid working relationship, if the harassment actually occurred through a delict, and if the act occurred within the course and scope of employment. The best way for employers to minimize their liability for sexual harassment is the implementation of training and educational policies that serve to make employees aware of what is permissible in the workplace. This will aid the employer in showing that it has done everything possible to reduce the risk of harassment, which will in turn serve to reduce the employer’s liability. To protect against the risk of expensive litigation, many employers are now investigating the matter of liability insurance – they would rather pay increased premiums than suffer alone when their employees take legal action against them. Sexual harassment is a problem that can only be solved through a concerted effort on the part of the legislature, judiciary, employers and employees. Together, these parties must ensure that all of those involved in the world of work are aware of the problem of harassment, as well as taking steps to educate and train employees so as to prevent it. Only in this way will we be able to take action to reduce this terrible problem in our country.

- Description: Plants possess a complex and poorly understood network of defence mechanisms that enable them to counteract the effects of abiotic and biotic stress. Aphid phloem feeding is source of biotic stress in plants. Russian wheat aphid and Bird Cherry-Oat aphid feeding cause significant losses in the annual wheat crop, and control by conventional methods such as pesticide application, has proved to be ineffective. Infestation by the Russian wheat aphid has a particularly devastating effect in South Africa. Aphid-resistant wheat cultivars have been identified but an incomplete understanding of the mechanism of the plant’s resistance thwarts the development of improved cultivars. A two-dimensional gel electrophoresis method was developed, partially optimised and validated in order to determine the effect of Russian wheat aphid and Bird Cherry-Oat aphid phloem feeding on the Betta and Betta DN wheat proteome. Differentially expressed proteins that were up or down regulated more than two fold were identified using PDQuest™ Basic software and matched to known wheat proteins stored in the SwissProt protein database on the basis of their molecular mass and isolectric point. Initial analysis of the differential protein expression of Betta and Betta DN wheat in response to Russian wheat aphid and Bird Cherry-Oat aphid phloem feeding at different growth stages revealed that younger plants display higher levels of resistance than older plants. Feeding by the Bird-Cherry Oat aphid does not result in the upregulation of proteins implicated in a defence response, which indicates that the damage incurred by the plant due to feeding by this aphid is not enough to trigger a classic defence response. Feeding by the more damaging Russian wheat aphid resulted in a stress response in susceptible wheat cultivar Betta, and a defence response in resistant wheat cultivar Betta DN. The infestation of Betta DN resulted in the upregulation of putative thaumatins and amylase trypsin inhibitors, indicating that the Betta DN resistance response could be due to the combined effect of protease inhibitors that discourage aphid phloem feeding and the activation of the salicylic acid and jasmonic acid plant defence pathways.

- Description: This study deals with the impact of HIV/AIDS on women living in chronic poverty. The question arises: Do we focus on their HIV/AIDS stories only or do we include their other lived experiences? This phenomenological study, on two sets of three generations of women infected and affected by HIV/AIDS and living in poverty, is an attempt at understanding the way the women experience their lifeworlds, not only their HIV/AIDS stories. One set includes a grandmother, her daughter who is living with full-blown AIDS, and her granddaughter, while the other includes a grandmother, her daughter and her granddaughter infected with HIV. The initial focus of the study was on the women’s HIV/AIDS narratives. However as the study progressed, especially during the interviews, it became apparent that the women’s generational poverty or chronic poverty was of greater concern to them than the HIV/AIDS that they were experiencing. Of the six participants, only one woman centred her life story on HIV/AIDS. This finding echoes other studies on HIV/AIDS among poor women: that chronic poverty is more threatening to the women than the risk or reality of AIDS. As a phenomenological researcher my aim was to focus on the participants’ own interpretations of the studied phenomenon. However, this was inadequate in accounting for the role that social structures play in shaping and informing the women’s subjective consciousness and experience. For this reason, I used feminist ideas to understand and interpret the women’s patriarchal experiences.

- Description: The general health status of pregnant women depends largely on the quality of the antenatal services available to them. The provision of good antenatal services ensures early detection and prompt management of any complication or disease that may adversely affect pregnancy outcome. In order to ensure high quality care, antenatal services need to be evaluated at regular intervals, both from provider and client perspective, to ensure their effectiveness in improving the health status of pregnant women. The midwife, as the first contact person for most pregnant women attending antenatal clinics in South Africa, has the potential to play a major role in improving the health status of these women. However, for the midwife to be effective in achieving this, antenatal services need to be effectively utilized by women. One of the factors that affect utilization of any service is client satisfaction with the service being rendered. This study, therefore, explores the perceptions that pregnant women have of the care that they receive from midwives at the selected antenatal clinics. The objectives of the study are to: {u100083} Explore and describe the perceptions and experiences of pregnant women attending antenatal clinic regarding the care they receive from midwives. {u100083} Make recommendations to assist registered midwives in optimizing the accompaniment of women during the antenatal period. A qualitative, descriptive, exploratory and contextual design was used for the study. The sample was chosen from the target population by means of purposive sampling and data was collected through unstructured interviews with the participants. Before data collection, permission was obtained from the Eastern Cape Department of Health and the Nursing Service Manager of the Gateway clinic, in the district hospital where the research was conducted. The Nursing Service Manager was acting as a Medical Superintendent at the time of the study. Written, informed consent was obtained from all participants before conducting interviews. Trustworthiness was ensured by means of Guba’s model throughout the study, and the aspects of truth value, applicability, consistency and neutrality were considered. Tesch’s eight steps of data analysis were used to analyze the data collected, and four main themes were identified namely: • Women perceive midwives as considerate and knowledgeable • Women perceive midwives as lazy and rude • Women experience mixed emotions about the care they receive from midwives • Though their experiences, women identified certain needs in the services and care they received at the clinic. Conclusions were drawn and recommendations for midwifery practice made based on the results of the study, with the aim of improving antenatal services rendered to pregnant women.

- Description: The promulgation into law of the concept of workplace forums has been beset with immense criticism and opposition from organized labour and some quarters of organized business. Last ditch efforts by the Ministerial Task Team had won the day for the inclusion of this controversial provision in the new Labour Relations Act.1 Commentators on the Act tend to agree that the fallout with organized labour at the negotiations has probably set the scene as to whether the provisions would be widely used or not. History has shown that the establishment of such forums in workplaces has been low. In some situations where workplace forums had been established, their continuous sustainability was put into doubt. This has led to the de-establishment of some of these forums in some workplaces. Various reasons were provided, but the prime factors for its failure could be traced back to the negotiations at NEDLAC. The unions opposed the original proposal by government that minority unions and even non-union employees can trigger the establishment of a workplace forum and insisted that this be restricted to majority unions. The voluntary nature regarding the establishment of a workplace forum and the trigger that only a majority union can invoke the provisions has still seen unions reluctant to utilize the provisions since it did not serve their purpose. The aims of the provisions, namely to increase workplace democracy, was therefore thwarted in favour of more informal procedures. Although the idea is a noble one, it is argued that the introduction of the provisions was ill-timed and inappropriate. The lesson that the legislature can take is that for any provision to be a success, buy-in from all stakeholders is paramount. Research has shown that there was a steady decline in the establishment of workplace forums. Since December 2004 there was not a single application received by the Commission for Conciliation, mediation and Arbitration. There is also doubt as to whether any of the Forums that were previously established are still functional. What is certain is that statutory workplace forums is not at the forefront as a vehicle for change that was envisaged in the Explanatory Memorandum that accompanied the new Labour Relations Act. What is also certain is that employers and employees are utilizing other forums to ensure workplace participation. These forums, however, only provide a voice to unionized workers. The vast majority of non-union workers remain voiceless. The proposed amendments in 2002 that intimated that the trigger be any union and not only majority unions failed to be passed into law. Perhaps it is that type of catalyst that is required to give life to the provisions. The future of workplace forums in South Africa is bleak and will continue to be if there is no intervention by the parties at NEDLAC to revive it. A complete revamp of the legislation would be required for such a revival. Some commentators have made meaningful suggestions on changes that can be made to the legislation to make workplace forums more attractive. Some have suggested it be scrapped altogether and future workplace participatory structures should be left to the parties to embrace voluntarily. Workplace forums are a novel innovation with great potential to encourage workplace democracy. There is nothing wrong with the concept. The application of such forums in the South African context is what is concerning. Perhaps prior experience and experimentation with similar type forums have tarnished workplace participation. The strategies by the previous regime and some employers have caused such participation to equate to co-option.

- Description: The promulgation into law of the concept of workplace forums has been beset with immense criticism and opposition from organized labour and some quarters of organized business. Last ditch efforts by the Ministerial Task Team had won the day for the inclusion of this controversial provision in the new Labour Relations Act.1 Commentators on the Act tend to agree that the fallout with organized labour at the negotiations has probably set the scene as to whether the provisions would be widely used or not. History has shown that the establishment of such forums in workplaces has been low. In some situations where workplace forums had been established, their continuous sustainability was put into doubt. This has led to the de-establishment of some of these forums in some workplaces. Various reasons were provided, but the prime factors for its failure could be traced back to the negotiations at NEDLAC. The unions opposed the original proposal by government that minority unions and even non-union employees can trigger the establishment of a workplace forum and insisted that this be restricted to majority unions. The voluntary nature regarding the establishment of a workplace forum and the trigger that only a majority union can invoke the provisions has still seen unions reluctant to utilize the provisions since it did not serve their purpose. The aims of the provisions, namely to increase workplace democracy, was therefore thwarted in favour of more informal procedures. Although the idea is a noble one, it is argued that the introduction of the provisions was ill-timed and inappropriate. The lesson that the legislature can take is that for any provision to be a success, buy-in from all stakeholders is paramount. Research has shown that there was a steady decline in the establishment of workplace forums. Since December 2004 there was not a single application received by the Commission for Conciliation, mediation and Arbitration. There is also doubt as to whether any of the Forums that were previously established are still functional. What is certain is that statutory workplace forums is not at the forefront as a vehicle for change that was envisaged in the Explanatory Memorandum that accompanied the new Labour Relations Act. What is also certain is that employers and employees are utilizing other forums to ensure workplace participation. These forums, however, only provide a voice to unionized workers. The vast majority of non-union workers remain voiceless. The proposed amendments in 2002 that intimated that the trigger be any union and not only majority unions failed to be passed into law. Perhaps it is that type of catalyst that is required to give life to the provisions. The future of workplace forums in South Africa is bleak and will continue to be if there is no intervention by the parties at NEDLAC to revive it. A complete revamp of the legislation would be required for such a revival. Some commentators have made meaningful suggestions on changes that can be made to the legislation to make workplace forums more attractive. Some have suggested it be scrapped altogether and future workplace participatory structures should be left to the parties to embrace voluntarily. Workplace forums are a novel innovation with great potential to encourage workplace democracy. There is nothing wrong with the concept. The application of such forums in the South African context is what is concerning. Perhaps prior experience and experimentation with similar type forums have tarnished workplace participation. The strategies by the previous regime and some employers have caused such participation to equate to co-option. Perhaps not enough spade work was done to ensure that the climate and attitude of the parties was conducive for its introduction. What is paramount no matter the form it takes is that workplace participation is crucial for economic growth and the introduction of new work methods to improve productivity. Without the establishment of such forums, whether voluntary or statutory, the ‘second channel principle’ that promotes non-adversarial workplace joint decision-making would be lost and conflict based participation could spiral leading to economic disaster.
