- Description: The Labour Relations Act contains a definition of a strike which reads as follows: “’strike’ means the partial or complete concerted refusal to work, or the retardation or obstruction of work, by persons who are or have been employed by the same employer or by different employers, for the purpose of remedying a grievance or resolving a dispute in respect of any matter of mutual interest between employer and employee, and every reference to ‘work’ in this definition includes overtime work, whether it is voluntary or compulsory.” The Labour Relations Act offers strikers special protection against dismissal if they conform with the Act and its provisions. Hence the distinction between those strikes and protest action in compliance with the Act, namely ‘protected’ strikes and protest action, and those strikes and protest action in violation of the Act, namely, ‘unprotected’ strikes and protest action. Participation in an unprotected strike is one form of misbehaviour. The Labour Relations Act expressly prohibits the dismissal of employees engaged in a lawful strike. Employees engaged in strike action contrary to the provisions of the Labour Relations Act may be dismissed since their strike action is deemed to be a form of misconduct. The dismissal of striking employees must be both substantially and procedurally fair.

- Description: In the past 20 years the defence of provocation has shifted from the periphery of South African law to a fully developed defence available to those who kill when provoked. Not only is the defence available to the provoked, but it has been extended to those who kill when subjected to emotional stress. However, the defence is mirred in controversy and bad decisions. Not only has the precise nature of the defence not been clarified, but this lack of clarity has been exacerbated by confusing decisions of our courts. This confusion is partly a result of the development of the defence of incapacity, particularly its extension to cases involving provocation and mental stress, and partly a result of its application in practice. Three major problems have plagued the provocation defence. Firstly, the courts have confused the defence of sane automatism with that of non-pathological incapacity. Secondly, there has been an implied use of an objective test in determining criminal incapacity where the enquiry has clearly been a subjective one. Thirdly, it has been held that the problem may not so much be the subjective aspect of provocation, but rather its application. The real problem seems to lie in the theoretical confusion as to the precise meaning of lack of “selfcontrol”. Lastly, on occasion the courts have failed to distinguish lack of capacity from diminished responsibility. Thus, in order to gain clarity concerning this “grey” area of the law these problems have created, it is necessary for South African law to consult more authoritative sources to receive guidance for the problems identified. One of those sources that has been consulted is that of English law. English law, however, deals with the defence of provocation in a different manner. Raising a defence of provocation here does not result in an acquittal but rather in a reduction of the charge to manslaughter. However, the English law on provocation is also 7 plagued by various problems. Firstly, there is the issue of cumulative provocation. Generally, there is little difficulty in cases where there is no “immediate trigger”. Secondly, the fundamental flaw with the current test of the reasonable man is that the courts have had to swing between the two aims of taking a compassionate view of human frailty while endeavoring to maintain an objective standard of the reasonable man. Lastly, it can be said that the problem with the proportionality requirement is that it makes the provocation defence dependant upon the assessment of the accused’s conduct after he or she lost his or her selfcontrol rather than on his or her giving way to passion and losing control in the first place. It is clear that from the problems identified in both South African law and English law concerning the defence of provocation the courts in each jurisdiction will have to pay careful attentio n to the problems highlighted and apply the law in such a way so as to ensure clarity and legal certainty.

- Description: This research is based on the hypothesis that response-based approaches to teaching literature and an outcomes-based system of education (OBE) are conceptually incompatible. This thesis claims that reader response involves processes that cannot be accommodated pedagogically within a system based on pre-determined outcomes. Furthermore, the kind of assessment prescribed by OBE is inappropriate to the nature of reader response. The hypothesis is based on three main premises. The first is that each reader brings a highly individual and complex set of personal schemata to the reading of imaginative texts, and these schemata have a decisive influence on the nature of a reader’s response. This means that response during imaginative engagements with literary texts tends to be idiosyncratic, and therefore largely unpredictable. Because of this, it would be inappropriate for a teacher, working within an OBE system, to try to teach towards pre-selected outcomes and to attempt to ensure that these outcomes, based on responses to literary texts, are in fact achieved. The second premise is that readers’ imaginative engagements with literary texts are essentially hidden events, which even the individual reader cannot fully bring to the surface and articulate. Because they are complex, and to some extent inaccessible, it would be inappropriate to assess the processes of response in the form of tangible evidence that a particular kind of response has taken place, or an outcome achieved. The third premise is that responses need time to grow and develop and do not merely happen quickly and cleanly. Consequently, aesthetic response, already a complex and inaccessible process, has no clearly distinguishable beginnings or endings. It would therefore be inappropriate to try to pinpoint the exact nature and parameters of a particular response or fragment it into a discrete unit of competence or knowledge. A two-dimensional problem emerges. The first is a conceptual one: whether there is an inherent tension between encouraging response to imaginative literature on the one hand, and accepting the rationale for OBE, on the other. The second dimension of the problem is empirical: whether teachers of literature experience any tension of either a conceptual or a practical nature when following response based approaches within the OBE system of Curriculum 2005, and if so, what they do in order to cope. In exploring the conceptual problem, the argument of this thesis is supported by reception theory and reader response criticism. The former provides key theoretical principles and insights that illuminate the nature of aesthetic reading, while the latter describes and analyses the nature, extent and manifestations of response in educational contexts, underpinned by both reception theory and empirical research. Together they offer evidence that personal response is determined by a complex range of processes, and is the core activity in reading for aesthetic purposes. This thesis also examines the conceptual basis and the structure of OBE as interpreted in both Curriculum 2005 and the revised National Curriculum Statement. The purpose of this is to establish the extent to which the philosophy and modus operandi of these curricula are rooted in notions of competence, and the requirement that learners give tangible demonstrations of pre-determined outcomes being achieved. If it is found that the curricula do lean heavily on pre-determined outcomes in regard to competencies that must be demonstrated, it may be concluded that 1) reader response activities are incompatible with OBE in a South African context, and 2) the potential exists for such incompatibility to create obstacles to creative and effective literature teaching. This can lead to difficulties for the teacher, who will then have to adopt acceptable strategies to cope with the situation. These strategies may ultimately be to the detriment of the pupils, particularly if the teacher seeks a compromise between genuine response and the kinds of activities that would yield precise, palpable measures of attainment that can be easily demonstrated. Exploring the empirical dimension of the problem involves investigating the responses of both teachers and teacher trainers to the experience of promoting response-based literature teaching and learning in an OBE environment. In order firstly investigated whether the practitioners do encourage reading response as a core activity in reading for aesthetic purposes. The extent to which practitioners have a sound grasp of the conceptual issues relevant to this research is also investigated. Insight into such issues depends on teachers and teacher trainers understanding the nature of reader response, on the one hand, and the rationale and structures of the relevant OBE curricula, on the other. Whether, and to what extent, practitioners experience tensions through their awareness of conceptual incompatibilities is also investigated. It should be borne in mind that practitioners work in real contexts in which a variety of complex factors play a role in determining how they respond to pressures from the environment. It cannot therefore be expected that teachers and others involved in delivering the curriculum will be able to reflect on purely conceptual issues without being influenced to an extent by more practical or logistical considerations. However, this study argues that the extent to which they are able to identify the relevant factors that affect the conceptual underpinnings of their practice will determine the degree to which their responses support the argument of this thesis. Together, the empirical and the theoretical findings offer qualitative evidence that should illuminate the nature and extent of the problem.

- Description: A comprehensive study involving 52 microtidal beaches spanning from reflective to dissipative states and located in tropical, subtropical and temperate regions in the Atlantic, Pacific and Indian oceans was carried out to unravel the relative roles of latitude and beach morphodynamics in determining beach macrobenthic species richness, abundance, biomass and mean individual body sizes. Since beach slope is one of the most important factors controlling beach fauna, a model based on beach geometry was applied to the sub-aerial beach deposit to understand the role of physical factors in predicting equilibrium beach slopes. Additionally, it was tested if the occurrence of beach types is related to latitude, and how physical factors change with morphodynamics and latitude. The beach morphometric model makes three assumptions: 1) that the cross-section of a beach deposit is equivalent to a right-angled triangle, 2) that the physical hydrodynamic factors (wave height and spring tide amplitude) and the beach deposit characteristics (sand grain size, beach slope and width) are interchangeable with their geometric counterparts producing an equation to explain beach geometry, and 3) that the predicted beach slope is in equilibrium with the hydrodynamic and sedimentological forces. The equation for predicting beach slope was derived and then tested against field data collected over 52 beaches. The predicted slopes were not significantly different from the observed slopes of the studied natural beaches. However some estimated slopes were different than observed ones. Possible sources of deviation between calculated and observed slopes may be the systematic sampling errors associated with field data. Alternatively, observed slopes could be the result of past hydrodynamic conditions, explaining the differences with the slopes calculated by the beach morphometric model, which assumes a state of equilibrium between beach slope and hydrodynamic conditions. A higher correlation of beach faunal structure with observed slopes rather than with present hydrodynamic conditions could then be indicative of faunal responses to previous hydrodynamic conditions in the same way was the observed slopes. The beach morphometric model could therefore be also useful in predicting faunal responses to changing hydrodynamic conditions. Since the model does not consider wave period, it is concluded that further tests should be done using laboratory and time-series field data and incorporating the role of wave period and beach permeability to ascertain its predictive value. Tropical regions had significantly more beaches in a reflective state than temperate and subtropical regions. Some tropical beaches were fronted by coral reefs, which not only provided coarse carbonate particles, but also additionally dissipated the low wave energy present in these climatic areas. Only one dissipative beach with high energy was found in the tropics, in southeast Madagascar. Temperate and subtropical regions, on the other hand, were dominated by dissipative beaches with medium to fine sands. Open oceanic reflective beaches were non-existent in the subtropics and rare in temperate regions, only occurring in estuaries, enclosed bays or on islands facing the continent. Intermediate beaches were more common in the subtropics but also occurred frequently in the other two regions, having higher energy in temperate regions. Reflective beaches had significantly steeper slopes, coarser sands, smaller waves and shorter swash lengths when compared to dissipative beaches. Additionally, reflective beaches were narrower, had deeper water tables and in consequence shorter saturation zones. Wave periods and surfzone widths were on average larger on dissipative than on reflective beaches. The frequency of occurrence of beach types is therefore related to the climatic signature of each latitude. Mid latitudes would be predicted to have more dissipative beaches with large and long waves because of their proximity to the storm generating belt around 50-60° S - these beaches will have a predominantly finer sands because of the input by rivers in rainy areas. Lower latitudes will have more reflective beaches due to a modal low energy wave climate and also because of the presence of inshore and offshore biotic structures such as coral reefs that dissipate even more the energy from the waves. Tropical and subtropical regions had larger marine species pools than temperate regions. After controlling for biogeographical differences in total species pool, dissipative beaches were on average significantly richer than intermediate and reflective beaches. Crustaceans were also more diverse on dissipative beaches, this difference being not significant for either molluscs or polychaetes. Significant relationships were found between total beach species richness (with or without terrestrial species), crustacean and mollusc species richness with beach morphodynamics as represented by the Dean’s index. Indices incorporating the role of tide, such as BSI, were less important in predicting species richness on the microtidal beaches studied here. Several other physical factors were also significantly correlated with species richness, the most important being the Beach Deposit Index, i.e. BDI, a composite index of beach slope and grain size. The highest correlation was between BDI and relative species richness, i.e. local beach species richness / regional species richness. Total regional marine species richness was higher in Madagascar and North Brazil (tropical beaches) than in Southeast Brazil (subtropical), or the West Coast of South Africa and South-Central Chile (temperate beaches). Not only was the pool of species capable of colonizing beaches richer in tropical and subtropical regions, but also local diversity of each morphodynamic beach type was higher among tropical beaches than their temperate counterparts. Although the results of this study agree with the predictions of the swash exclusion hypotheses, several reflective and intermediate beaches had higher species richness than predicted before and this seems to be linked to the presence of finer sediments and a less turbulent flow for larvae to settle. It is concluded that beach species richness is not necessarily controlled by one major morphodynamic parameter; this control is complex and probably involves multiple interacting biotic (biological interactions) and abiotic (e.g. grain size, wave height, beach slope and width, water table) factors. Species richness seems to be controlled on two different scales: on an evolutionary one where tropical and subtropical regions have higher regional and local diversity due to higher speciation rates; and on an ecological scale, where fine grained sand beaches have their carrying capacity enhanced by higher larval settlement rates and survival of recruits towards adulthood. On average dissipative beaches had higher total densities and macrofaunal abundances than reflective ones. Crustaceans, terrestrial species and cirolanid isopods such as Excirolana spp. were also more abundant on dissipative beaches. The difference was not significant for molluscs and polychaetes. Significant relationships were found between total abundance, crustacean species richness and beach morphodynamics as represented by the Dean’s index. Again, BSI was less important than individual physical factors in determining faunal abundance on the studied microtidal beaches. Several other physical factors were also significantly correlated with abundance, the most important being the Beach Deposit Index (BDI). The highest correlation was between BDI and total macrofaunal abundance. Factors related to surf zone processes, and possibly productivity, were highly correlated with total community, crustaceans, Excirolana spp. and terrestrial species abundances. The abundances of polychaetes and molluscs were better correlated with factors related to the beach deposit (BDI, slope, grain size and water table depth). Significant differences were observed between latitudinal regions for the average beach and also for each beach type. In general temperate beaches harboured larger community densities and abundances, and also crustacean, Excirolana spp. and terrestrial abundances. Mollusc and polychaete abundances were larger on subtropical and tropical beaches. The control of abundance on a sandy beach is complex and involves multifactorial processes at evolutionary and ecological scales. At evolutionary scales animals seem to attain higher abundances in the region where they first evolved, e.g. amphipods and isopods in temperate regions. At ecological scales they attain higher abundances where productivity is higher (total macrofaunal, crustaceans, Excirolana spp., terrestrial spp.) or where the settlement environment is more benign (molluscs and polychaetes). Dissipative beaches supported larger average and total community biomass than reflective beaches. Crustaceans, terrestrial species and cirolanid isopods such as Excirolana spp. also had larger biomass on dissipative beaches. The difference was not significant for molluscs and polychaetes. Significant relationships were found between the biomass of community and taxonomic groups with beach morphodynamics as represented by the Dean’s morphodynamic index. On the microtidal beaches studied here, BSI was less important than other morphodynamic indices and single physical factors in determining faunal biomass and mean individual body size. Surf zone characteristics such as wave height, period and surf zone width had the highest correlations with community, crustacean.

- Description: To know your law and not to understand it is like a legal barbarian lost in the battlefield of legal theory. A proper and thorough understanding of the law of evidence and hearsay evidence in particular, is of paramount importance not only for lawyers but also for persons who regard themselves as labour law experts. It takes a great deal of experience before a lawyer truly becomes confident with the law of evidence and its application. The only way one becomes good at it is firstly to know the law. (Where does it come from and why is it there?) Then one must get to understand it by looking at examples and apply it in practice. Only then will a person gain practical experience. The aim of this treatise is not to try and educate experienced lawyers. This article is aimed at those that need some motivation to pursue their journey in the labour law process. Remember we all assume that lawyers know and understand their subject until they proof the contrary. In this work I shall try to highlight the importance of the law of evidence in labour law proceedings. Firstly the meaning of the law of evidence and hearsay evidence is considered. Further emphasis will be on the approach and application of the law of evidence, and in particular the hearsay rule, in labour law proceedings.

- Description: The right to legal representation at labour proceedings of an administrative or quasi-judicial nature is not clear in our law, and has been the subject of contradictory debate in the South African courts since the1920’s. Despite the ambiguities and uncertainty in the South African common law, the statutory regulation of legal representation was not comprehensively captured in labour legislation resulting in even more debate, especially as to the right to be represented by a person of choice at these proceedings in terms of the relevant entrenched protections contained in the Bill of Rights. The Labour Relations Act 12 of 2002 (prior to amendment) is silent on the right to representation at in-house disciplinary proceedings. Section 135(4) of Act 12 of 2002 allows for a party at conciliation proceedings to appear in person or to be represented by a director or co employee or a member or office bearer or official of that party’s registered trade union. Section 138(4) of the same Act allows for legal representation at arbitration proceedings, but subject to section 140(1) which excludes legal representation involving dismissals for reasons related to conduct or capacity, unless all parties and the commissioner consent, or if the commissioner allows it per guided discretion to achieve or promote reasonableness and fairness. The abovementioned three sections were however repealed by the amendments of the Labour Relations Act 12 of 2002. Despite the repealing provision, Item 27 of Schedule 7 of the Amendment reads that the repealed provisions should remain in force pending promulgation of specific rules in terms of section 115(2A)(m) by the CCMA. These rules have not been promulgated to date. The common law’s view on legal representation as a compulsory consideration in terms of section 39 of the Constitution 108 of 1996 and further a guidance to the entitlement to legal representation where legislation is silent. The common law seems to be clear that there is no general right to legal representation at administrative and quasi judicial proceedings. If the contractual relationship is silent on representation it may be permitted if exceptional circumstances exist, vouching such inclusion. Such circumstances may include the complex nature of the issues in dispute and the seriousness of the imposable penalty ( for example dismissal or criminal sanction). Some authority ruled that the principles of natural justice supercede a contractual condition to the contrary which may exist between employer and employee. The courts did however emphasize the importance and weight of the contractual relationship between the parties in governing the extent of representation at these proceedings. Since 1994 the entrenched Bill of Rights added another dimension to the interpretation of rights as the supreme law of the country. On the topic of legal representation and within the ambit of the limitation clause, three constitutionally entrenched rights had to be considered. The first is the right to a fair trial, including the right to be represented by a practitioner of your choice. Authority reached consensus that this right, contained in section 35 of the Constitution Act 108 of 1996 is restricted to accused persons charged in a criminal trial. The second protection is the entitlement to administrative procedure which is justifiable and fair (This extent of this right is governed y the provisions of the Promotion of Access to Administrative Justice Act 3 of 2000) and thirdly the right to equality before the law and equal protection by the law. In conclusion, the Constitution Act 108 of 1996 upholds the law of general application, if free and justifiable. Within this context, the Labour Relations Act 66 of 1995 allows for specific representation at selected fora, and the common law governs legal representation post 1994 within the framework of the Constitution. The ultimate test in considering the entitlement to legal representation at administrative and quasi judicial proceedings will be in balancing the protection of the principle that these tribunals are masters of their own procedure, and that they may unilaterally dictate the inclusion or exclusion of representation at these proceedings and the extent of same, as well as the view of over judicialation of process by the technical and delaying tactics of legal practitioners, against the wide protections of natural justice and entrenched constitutional protections.

- Description: Due to the diverse functions of Fc eRII, such as its roles in cellular adhesion, growth and differentiation of B and T lymphocytes, rescue of B cells from apoptosis and release of cytotoxic mediators, it is clear why it is believed to be a central molecule in allergic response. Because of its important role in the regulation of IgE production, FceRII may be the primary cause of certain allergic conditions. This study attempted to express and purify a recombinant human soluble FceRII to test its effect on a B-lymphoblastoid (RPMI 8866) and a monocytic (U937) cell line. The protein was expressed in Escherichia coli inclusion bodies, before being refolded and purified in a single gel chromatography step. This pure protein was then tested for biological activity by testing its IgE binding func tion. Once proven functional, it was used to test its effect on the cell lines at three concentrations for its apoptotic rescue properties and its cytokine effects. The recombinant protein did not seem to have any significant effect on the apoptotic rescue of either cell line. While the recombinant sFceRII appeared to have a slight effect on the stimulation of IL-1ß and TNFa in the RPMI 8866 cells, there was no apparent effect on the production of NF?B. In U937 cells, the protein did not seem to have any effect on the stimulation of IL-1ß, TNFa or NF?B. However, the cytokine effects of the recombinant protein were tested on isolated PBMCs from a healthy individual and a hyper-IgE syndrome patient. The recombinant protein was able to stimulate the production of cytokines in both individuals’ PBMCs, proving that it has the same effect as the natural protein. The upregulation of these cytokines indicates that the recombinant protein is able to stimulate the immune system. Therefore, this recombinant soluble FceRII protein could possibly be used for immune therapy.

- Description: Transformation in the arid succulent thicket of the Eastern Cape of South Africa in response to unsustainable livestock production has been widespread, with less than 10 percent remaining intact. Transformation in succulent thicket has resulted in large areas of dense thicket (comprising a two-phase mosaic of perennial-vegetated patches separated by animal paths and bare patches) being replaced with a ‘pseudo-savanna’ of remnant canopy trees with a structurally simple field layer of ephemeral and short- lived perennial grasses and forbs. There is an extensive literature describing the transformation of succulent thicket, with many speculative statements about the underlying mechanisms of transformation. The central focus of this study was to improve our mechanistic understanding of transformation in succulent thicket using field experiments. Hopefully these results will set another foundation upon which future management of succulent thicket can be improved and large-scale restoration initiated. This study comprises four themes that are linked to the concept of landscape function. The central premise of landscape function is that functional landscapes have mechanisms that capture and retain scarce resources. Conversely, as landscapes become increasingly dysfunctional, so these mechanisms become disrupted. In succulent thicket, dysfunctio n appears to be linked to the reduced ability to harvest water, cycle carbon and a loss of organic carbon. In this thesis I examined some of the key processes that influence water and organic carbon fluxes: perennial vegetation cover, soil fertility, litter fall and decomposition, and runoff and soil erosion. The experimental design that was used for all this work was a factorial ANOVA based on replicated fenceline contrasts that reflect differences in long-term management history. The main objectives of this thesis were to: quantify the patterns of transformation in an arid form of succulent thicket, including changes in the biomass, cover and structure of the dominant vegetation guilds; test the stability of the transformed succulent thicket ecosystem to show whether it is a new stable state or an intermediate stage in a trajectory towards a highly desertified state where only the ephemeral grasses and forbs persist; describe and compare soil fertility across transformation contrasts, concentrating on changes in the spatial patterns of soil resources and the ability of the soil to harvest precipitation; to compare litter fall and decomposition of leaf material from the dominant plants in intact and transformed succulent thicket; to quantify and compare run-off and erosion from run-off plots in intact and transformed succulent thicket. Transformation and stability I quantified the changes in plant diversity, physiognomy and biomass that occur across transformation contrasts. Thicket transformation results in a significant loss of plant diversity and functional types. There is also a significant reduction in the biomass (c. 80 t.ha-1) and structural complexity of the vegetation, both vertically and horizontally. These results were interpreted in terms of their implications for ecosystem functioning and stability. To test the stability of the transformed succulent thicket I used aerial photographs and ground-truthing to track the survivorship of canopy trees over 60 years in pseudo-savanna landscapes. I also measured seedling establishment in different habitats. I show that the pseudo-savanna is not a stable state owing to ongoing adult mortality and no recruitment of canopy trees. Soil fertility and water status I hypothesised that the above-ground changes in ve getation would be accompanied by similar trends in the pattern and levels of soil nutrient resources and the ability of the landscape to harvest precipitation. I compared soil fertility (organic carbon, available nitrogen and phosphorus), texture, matric potential, and surface micro-topography in the two main micro- habitats on either side of the replicated fenceline contrasts. The results show that intact spekboom thicket has a distinct spatial pattern of soil fertility where nutrients and organic carbon are concentrated under the patches of perennial shrubs, compared to under canopy trees and open spaces. Transformation results in a significant homogenisation out of this pattern and an overall reduction in the fertility of the landscape. The proportion of the landscape surface that would promote infiltration of water decreases from 60 – 0.6 percent. Soil moisture retention (matric potential) also decreases with transformation. I interpreted these patterns in terms of the ability of the landscape to harvest and release water after rainfall events. Litter fall and decomposition Surface litter and soil organic matter are critical components to wooded ecosystems; contributing to several ecosystem functions. The rates of litter fall and decomposition are ratelimiting steps in nutrient cycling and incorporation of organic matter into the soil. The ecological mechanisms behind the collapse of succulent thicket in the face of domestic herbivory are not fully understood, but are believed to include the breakdown of several ecosystem processes, including litter fall and decomposition. I quantified the changes in litter fall and litter decomposition of four of the dominant perennial woody plants (Euclea undulata, Pappea capensis, Portulacaria afra and Rhus longispina) across the replicated fenceline. Litter fall was measured over 14 months using mesh traps. Decomposition was measured over 15 months using a combination of litterbags and unprotected leaf packs. I also quantified soil microclimate during the experimental period; hypothesising that transformation would lead to soil conditions less amenable for biotic activity. Litter fall in succulent thicket was very high for a semi-arid system, comparing more to temperate forests. The leaf-succulent P. afra contributed the largest single component of the total litter production at a landscape scale. The effect of transformation on litter fall was species specific. Deep-rooted or drought-adapted species showed no change in litter yield with transformation; shallow-rooted species showed a significant decrease. There were few significant differences in decomposition rates across the transformation gradient and between litter types. Portulacaria afra litter had the steepest rate of mass loss, and was most affected by transformation. The more recalcitrant (high C:N ratio) leaves of P. capensis remained largely unaffected by transformation. These results indicate the critical role of the perennial vegetation in incorporating organic carbon into the soil. Transformation of succulent thicket leads to a disruption of the flow of carbon into the soil, reinforcing the cycle of transformation through reduced fertility. Rehabilitation of this ecosystem will require the active establishment of species, such as P. afra, that will restart the flow of carbon into the soil. Run-off & Erosion The landscape function model predicts that functional semi-arid shrublands efficiently conserve limiting resources such as water and water-bourn sediments (soil and organic matter). As these rangelands become transformed through unsustainable livestock production, so their ability to conserve resources decreases. The primary determinant of landscape function and conservation of resources appears to be the proportional cover of perennial vegetation. I hypothesised that the switch from a two-phase mosaic dominated by perennial succulent and woody shrubs to a single phase system dominated by an ephemeral field layer would be accompanied by disruption of the mechanisms that conserve resources. Specifically, I tested the hypothesis that transformation of succulent thicket increases runoff volume, sediment concentration of runoff, soil erosion and loss of organic matter at a patch scale (c. 100 m2). Runoff and water-borne sediment were measured from runoff plots established across replicated fenceline contrasts. Data were collected from eight extreme weather events over two years. There were no significant differences between runoff and erosion across the transformation contrast, as each extreme weather event was unique in terms of its runoff response. The transformed runoff plots alone also gave inconsistent results, largely due to differences in the cover of ephemeral forbs and weakly perennial grasses. Runoff and erosion were not predictable from the data across the transformation gradient due to complex interactions between the nature of the above-ground vegetation, soil micro-topography and land use history. The results highlighted the need for longer-term catchment experiments to generate a predictive understanding of the effect of transformation on runoff and erosion in succulent thicket.

- Description: The construction industry is considered to be an extremely dangerous working environment, and therefore the health status of construction workers needs to be considered prior, during and on leaving the industry. Occupational hazards relative to the construction worker are well researched internationally; however few countries undertake routine medical surveillance to identify the health status of the construction worker relative to these hazards. Employers have a higher duty of care to identify workers who could be a risk at work from non-occupationally related conditions such as hypertension and diabetes mellitus. Work could exacerbate these conditions, leading to absenteeism, poor performance and eventually leaving the industry due to ill health. The dissertation explores, inter alia: the risks to which workers are exposed; the legal aspects; relevant literature regarding medical surveillance, and the use of a medical surveillance instrument used to determine the health status of 142 construction workers who consented to participate in the study. The methodological approach used in this study was a quantitative descriptive design, more specifically, using a randomised cross-sectional survey design. The instrument used to determine health status included a full medical, occupational and social history, as well as a physical examination undertaken by Occupational Health Nursing Practitioners (OHNs). Findings indicate that most construction workers believe they are healthy. However only a small percentage of construction workers did not require referral for further investigation and / or treatment.

The labour law consequences of a transfer of a business

- Description: The burden that South African labour law has to bear in relation to the economy is very heavy by international standards. In most industrially developed countries, the economy is strong enough either to provide jobs for most work-seekers or, failing that, an adequate social security system for households without breadwinners in place. In most developing countries with high unemployment rates, the labour law system makes only perfunctory effort to reach out to those facing economic marginalisation. South Africa, essentially a developing country, is not like that. The legal system is strong, works off a firm human rights base, and sets out to grapple with the issues. That is how it should be, but it comes at a price – an oftengraphic exposure of the limits of the law in a stressed society. Businesses operate for profit and survival according to the unsentimental ways of the market, and employees back in a bid to save jobs, lifestyles and livelihoods. The stakeholders use power when they have it, and make claims on the law when they don’t. The legislation and the case law reflect, add to and, to a degree, shape the complexities of these contests, and no more so than in the area of business restructuring.1 The new South Africa has quickly become the destination for foreign investment. The weakness of the rand against the dollar, pound, euro and with the “cost to sell and produce” being so low against these currencies, players on the corporate stage constantly change their make-up and composition. The larger engulfs the smaller, one company buys shares in another, or buys it out entirely, or all or part of its assets, and others are liquidated. In all these situations, employees in South Africa may find themselves with new bosses on the morning after. Under common law employees in this situation were deemed to have been discharged by the former employer, whether or not they have been offered positions in the transformed structure. If they did not want to work under it, they could not be forced to do so. That was because an employment contract was deemed in law to be one of a personal nature that could not be transferred from one employer to another without the employees consent. This research is conducted at an interesting time, when the amendments to the Labour Relations Act 66 of 1995 in respect of the transfer of a business, and in particular section 197, dealing with such matters comes into effect. It is also interesting in the sense that most judgements of the Commission for Conciliation, Mediation and Arbitration (CCMA) and judgements of the Labour Court were moving more or less to a common approach or interpretation of section 197 of the Labour Relations Act 66 of 1995 (hereinafter “the LRA”). Section 197 of the LRA sought to regulate the transfer of a business as a going concern and altered the common law regarding the transfer of a business in two situations – firstly when there is no insolvency, factual or legal, concerned, and secondly in the instance where the transferor is insolvent. The first extreme was when an employer is declared insolvent and the contracts of employment terminated automatically. The second extreme was from the first whereby the employer has to terminate the services of his employees and be liable to pay severance pay in terms of section 1893 of the LRA, which has also been amended along with section 197 of the LRA. It is as if this section was introduced to remedy these extremes. These extremes will be dealt with in detail in this paper. The transfer of goodwill and assets from the seller to the buyer occurs when a business is sold as a going concern. At common law the employees of a business cannot be transferred in the same manner. The Labour Relations Act 66 of 1995 altered this position. By enacting this section the legislature wanted to protect the interest of the employees in such transactions. Whether the legislature has succeeded or not is a matter that will be dealt with in this paper. It is all dependent on the interpretation of this section by the commissioners and judges. By including section 197 in the LRA, the legislature’s intention was to resolve the common law problem where employment contract terminated upon the sale of a business, and this section was intended to be an effective tool for protecting the employment of employees. In order to understand the labour law consequences of the transfer of a business, it is important to understand the provisions of sections 197 and 197A of the Labour Relations Amendment Act 2002. This will be dealt with and each section will be discussed in detail using relevant case law and literature. In considering investing in a South African based company by way of purchasing a share of the company and giving it your own flavour, one has to carefully consider the effects of this transaction. Companies wishing to restructure, outsource, merge or transfer some of its operations will need to understand what the implications of the labour legislation will have on their commercial rationale. Section 197 regulates the employment consequences when a transfer of a business takes place. This is defined to mean the transfer of a business by one employer (the old employer) to another employer (the new employer) as a going concern. Business is defined to include the whole or part of the business, trade undertaking or service. Like the current provision, the new provision referrers to the transfer of a business. It is therefore a wider concept than the sale of a business.4 No attempt is made to define what constitutes a going concern and the controversial issue of whether an outsourcing exercise can constitute a going concern transfer is also not explicitly dealt with. The fact that a business is defined to include a service may be an indication that it was intended to typify outsourcing as a going concern transfer, but this is not necessarily the case.5 The amendments to the Act6 came into effect on 1 August 2002. Sections 197 and 197(A) of the Act consequently seeks to regulate the transfer of a business. These regulations will be dealt with individually and in a format that would make each of the sections in sections 197 and 197(A), easy to understand and interpret. It will also become clear as to what the implications of each of the subsections will have on that commercial rationale. The issues highlighted above will be dealt with detail in this paper giving an overview of the Common Law, the Labour Relations Act 66 of 1995 and the new Labour Relations Amendment Act 2002.

The law relating to lock-outs

- Description: The lock-out is accepted as a necessary element of collective bargaining. The law relating to lock-out is considered as a legitimate instrument of industrial action. There are a number of procedural requirements for a legal lock-out. The dispute should be referred to a bargaining council (or where there is no bargaining council with jurisdiction, to a statutory council) or, failing which, the Commission for Conciliation, Mediation and Arbitration. If the bargaining/statutory council or the commission fails to resolve the dispute, it is no longer required that a ballet should be brought out in favour of the contemplated lock-out before the lock-out could be legal: all that is required is that the period of notice of the intended lock-out is given. The lock-out may either be protected or unprotected. It is protected if it is not prohibited absolutely and the various procedural requirements have been complied with. The protected lock-out is immuned from civil liability. On the other hand a lockout will be unprotected if it does not comply with sections 64 and 65 of the Labour Relations Act, 1995. In the circumstances the Labour Court has exclusive jurisdiction to grant an interdict or order to restrain any person from participating in unprotected industrial action and to order the payment of just and equitable compensation for any loss attributable to the lock-out. Lock-outs are prohibited in specific instances and allowed with some qualifications in others. For example, employers engaged in the provision of essential or maintenance services are prohibited from locking their employees out in order compel them to comply with their demand. Such essential services are Parliamentary services, the South African Police Service and a service the interruption of which endangers the life, personal safety or health of the whole. A distinction is also drawn between offensive and defensive lock-outs. Defensive lock-outs involve the closure of an employer’s premises or the shutting down of its operations during industrial action initiated by workers. The offensive lock-outs, also known as “pre-emptive lock-outs”, amount to an employer initiated form of industrial iv action where the premises are locked and workers are excluded and prevented from working. The law relating to lock-out in South Africa is clearly put in its proper perspective by the interim Constitution of the Republic of South Africa 200 of 1993, final Constitution of the Republic of South Africa 108 of 1996, Labour Relations Act 66 of 1995 and in Ex Parte Chairperson of the Constitutional Assembly: In re Certification of the Constitution of the Republic of South Africa.1 However the situation is unsatisfactory to employers. The interim Constitution guaranteed the “right to strike” and “recourse to the lock-out”. Under the final Constitution lock-outs enjoy no direct protection. The Constitutional Court’s certification judgement rejects the view that it is necessary in order to maintain equality to entrench the right to lock-out once the right to strike has been included. The Constitutional Court concluded that the right to strike and the right to lock-out are not always and necessarily equivalent. However the purpose of the lock-out is to settle collective dispute of the ways permitted by the Labour Relations Act, 1995. The purpose is not to terminate the relationship between the employer and the employee. The employer may not, for example, dismiss employees finally at the end of an unsuccessful lock-out in order to avoid the consequences of impending strike action by the employees.

- Description: Retrenchment, as a form of dismissal, is regulated by section 189 and 189A of the Labour Relations Act 1995. In order for a retrenchment to be fair, it must comply with both the substantive and procedural requirements stipulated in the Act. After an employee has proved the dismissal, the onus rests on the employer to comply with these two requirements by providing proof thereof. One of the most important procedural requirements that must be complied with by the employer is that the employer cannot merely make a decision to retrench. This decision may only be made once the employer, when contemplating a retrenchment, followed the lengthy consultation process as required in section 189. Recent amendments to section 189 introduced a distinction between a small and big employer and further between a large-scale and small-scale dismissal. If the employee is of the opinion that the employer did not comply with either the procedural or substantive requirements or both, he/she may refer such a dispute for conciliation and thereafter for arbitration or adjudication, according to a dispute resolution process contained in the Act, during which process certain remedies are available to the dismissed employee. The Labour Relations Act 1995 also introduced important amendments which have the effect that employees are allowed to, in certain circumstances, to strike over collective retrenchment disputes.

- Description: Sports law in South Africa is a field requiring exciting and intensive research. With so many sporting codes changing their status to professional sport, intensive research on the legal implications pertaining to each professional sporting code has also become necessary. Professional rugby in South Africa has grown into a multimillion rand industry. It is an industry whose role players need specialized legal advice on a multitude of issues. This dissertation addresses the legal issues arising out of the situation where a professional player is injured, during practice or a game, due to the intentional or negligent action of another. The medico-legal aspects of rugby, relating to causation and proof of injuries are an indispensable element of proving liability where rugby injuries are concerned. These aspects are crucial in assessing the criminal and delictual liability of players, coaches, referees, team physicians and even the union concerned. The problem of rugby violence, causing injury, is addressed by both the criminal law and the law of delict with the issue of consent being central to this discussion. Furthermore, the labour law implications can be far-reaching for both the player and the employer union due to the unique features of sport as an industry. All role players in professional rugby will have to cooperate with the legal community to ensure that a practical body of law is established in order to make rugby a safer sport for all concerned and to protect the professional player from unnecessary, incapacitating injury.

- Description: It took 18 months of intensive negotiation at the Millennium Labour Council, NEDLAC and the Labour Portfolio Committee before the Labour Relations Amendment Act of 20021 completed its passage through Parliament, taking effect on 1 August 2002. Fifty-seven amendments to specific sections of the Labour Relations Act2 and its schedules cure some obvious anomalies in the original version. It is further apparent that the legislature has taken cognisance of the observations by judges and arbitrators, who voiced their criticism in respect of certain aspects of the original "Act". The amended "Act"3 does appear to be a genuine commitment by both business and organised labour to improve efficiency in the labour market, to promote employment creation and to protect vulnerable workers. Improved dispute resolution mechanisms, enforcement mechanisms and the resurgence of an unfettered discretion in awarding compensation go some way to improving the application of the "Act". The most dramatic amendments have taken place in the law regulating retrenchments by large employers, inclusive of the controversial introduction of a right to strike after retrenchments of this nature have been effected, and the regulation of the transfer of a business as a going concern and its impact on workers. Critics indicate that business and organised labour have subscribed to the package of amendments despite respective reservations and due to certain time constraints. The nett result is a package of amendments that could be described as failing to address, in certain respects, or intentionally overlooking, areas of the "Act" that have traditionally been shown wanting in the past. In the individual employment law sphere specifically, the failure to address the meaning of "benefits" in the definition of unfair labour practices; to allocate a precise meaning to the concept of the transfer of a going concern; or to regulate the conduct of employers when transferring employees, remain some of the areas for concern. It appears that the legislature has decided that certain issues should be resolved by the Labour Court, and ultimately the Labour Appeal Court, on a case-by-case basis rather than by legislative intervention. Whilst this approach has merit, it does present problems to those seeking to apply the provisions of the amended "Act" 5 in everyday practice. On the whole, the amendments do not, nor were they designed to, mark a major shift in the government's labour market policy. The changes clearly focus on correcting and clarifying sections of the "Act", which have resulted in unintended consequences, or lost touch with commercial reality, over the past seven years.

An analysis of legal rules applicable to domain names and problems related to the protection of domain names in South Africa, United State, United Kingdom and internationally is undertaken. The problems includes cybersquatting, misuse of personal names, reverse domain hijacking, misuse of meta tags and keywords. The treatise established possible solutions applicable to South Africa by investigating how other countries have dealt with such problems, and further investigated the extent to which South African legislation is suited to deal with such problems. An investigation of the regulation in terms of the Electronic Communications and Transactions Act 25 of 2002 is briefly attempted, and proposals for the future on the South African domain name system suggested.

- 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: 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: 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.

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.

- Description: At the University of Port Elizabeth (UPE), the End User Computing course (EUC) acts as a service course for many departments. This implies that many students are forced by their curricula to register for this course. The ever-increasing numbers in EUC place a considerable load on existing human and physical resources. In lecture groups of 120 –160, students rarely get the attention they need, and the pace at which the content is delivered (too slow or too fast) may also inhibit the learning process. During an initial investigation into E-learning at UPE in 1999, a prototype virtual classroom was developed. There were, however, a number of problems with this prototype. Firstly, it was implemented using a number of different technologies, which made it difficult to extend and maintain. Secondly, it only addressed some aspects of an E-learning environment, which proved insufficient for the EUC course. In the existing EUC course at UPE, the students are already exposed to some E-learning concepts, as a section of their skills training component is handled by using multimedia software in a simulated environment. The objective of this project was to extend the E-learning component further to determine the advantages and disadvantages of using E-learning to support information technology (IT) education in a contact-university environment. This project included a literature search and survey of existing E-learning environments at other universities. This research was used to develop a draft framework for an E-learning environment. The framework was used to select a tool to create an E-learning environment at UPE. An experiment was designed using this E-learning environment to support two IT courses at different year levels. The results of the experiment were analysed using qualitative and quantitative methods to determine the impact of using E-learning to support IT education at UPE. The results of this research show that E-learning can be used to support IT education at UPE. More success, however, was achieved at postgraduate level than at first-year level. Making use of Elearning increased student satisfaction and promoted active learning, while providing benefits like convenience, communication, flexibility and scaffolding. We conclude, therefore, that E-learning can provide a flexible approach to IT education in a university environment in the future.
