- Description: This study sought opportunities to mitigate the pressures of land transformation and alien invader plants on commercial farm land in the thicket biome in the lower reaches of the Fish Kowie Corridor. It had two aims. Firstly, to determine the role incentives could play in mitigating these pressures. Secondly, to determine the characteristics of an incentive programme that would most effectively achieve this. In order to do this, an understanding of landowner activities, needs, opinions and barriers to behaviour; the nature of the pressures on thicket and the nature of the required behaviour to reduce these pressures; and current and past institutional arrangements needed to be achieved. This was done predominantly through a current literature review and personal interviews with landowners and key informants. These findings were used to make recommendations for an effective incentive programme. Landowners showed a preference towards tangible incentives, in particular management assistance, financial compensation and law enforcement. They indicated an aversion to an incentive programme implemented by a government agency, particularly district and provincial government. Rather, landowners showed a propensity towards a nongovernment organisation (NGO) or a farmers group implementing an incentive programme. It was recommended that the two major pressures, namely land transformation and alien invader plants, required different interventions by different agencies in order to be mitigated. The pressure of land transformation required a stewardship model response, with the primary drive being a non-contractual environmental extension service to landowners. The extension service should focus on promoting pro-conservation practises, raising awareness and disseminating information. It should also build a relationship of trust between landowners and the implementing agency. The pressure of alien invader plants would be most effectively addressed through the Working for Water programme. Tangible incentives must be provided to the landowner to induce the costly exercise of alien invader plant control. In particular, the high cost of labour must be addressed. The regulatory incentive of applying laws requiring landowners to control alien invader plants on their land should also be enforced.

- Description: With the emergence of the new field of resource economics, one now has the ability to value and to include natural resources in decision making. This thesis aims to explore the valuation of natural resources by reviewing the economic values, techniques, methods and ecological aspects of restoration. Assegaaibos mountain catchment in the Western Cape Province has been used as a case-study example. A cost-benefit analysis of the restoration of the mountain catchment, in terms of the direct benefits of water and tourism, has been performed. The costs of restoration were observed to see whether they outweighed the benefits (income) derived (water and tourism). The results show that the water and tourism benefits did outweigh the costs of a basic restoration scenario. However, the basic restoration scenario did not fulfil the ecological requirements of the project. The results also illustrated that in the moderate restoration scenario, costs only outweighed the benefits when a three percent discount rate was applied. With the optimistic restoration scenario, costs outweighed benefits only when an eight percent discount rate was used. In the comprehensive restoration scenario, costs were shown to outweigh by far the water and tourism benefits over a thirty-year time frame. However, it should be noted that the deterioration of the environment (accelerated erosion, reinvasion, reduced water quality) was not factored into the costs of failure to rehabilitate.

- Description: The WET-Management Series is a set of integrated tools that can be used to guide well-informed and effective wetland management and rehabilitation. Wetland loss in South Africa has been significant and the need for wetland rehabilitation as part of good wetland stewardship and management is compelling. National policy and legislation provide clear direction and support for rehabilitation, but the very complex links between people and wetlands mean that actions aimed at sustainably rehabilitating and conserving wetlands will depend on the dedication and commitment of all stakeholders, especially landowners and wetland users.

- Description: Acquired Immunodeficiency Syndrome (AIDS) is a human disease caused by the human immunodeficiency virus type 1 (HIV-1) and it is one of the biggest social, economic and health challenges in the world. The Joint United Nations Programme on HIV/AIDS (UNAIDS) and World Health Organization (WHO) estimated that between 33.4 to 46.0 million people around the world were living with HIV/AIDS in December 2005 and the highest estimates are in the Sub-Saharan Africa (around 25 million). In more developed countries a combined antiretroviral therapy called highly active antiretroviral therapy (HAART) is used, which results in reduced progression to AIDS in most patients. Despite the beneficial effects of HAART, significant side effects are experienced by treated patients. In addition, most infected people live in countries where the treatment is very expensive or, in many cases, not available at all. These people therefore rely on medicinal plants for health care. In this study, aqueous extracts from Sutherlandia frutescens and Lobostemon trigonus were screened for potential anti-HIV activities in a series of in vitro enzymatic assays, including reverse transcriptase, HIV-1 protease and glycohydrolases. Two extracts of Sutherlandia leaves (SFL-1 and SFL-2) were prepared that inhibited HIV reverse transcriptase and a Lobostemon leaf extract (LTL) was shown to also inhibit this enzyme. All extracts were assayed at 1.25mg/ml. Tannin content was determined for all active extracts using a tannic acid assay. SFL-1 and SFL-2 were found to contain about 6 percent and 7 percent tannins, respectively, and LTL contained 31% tannins by weight. Tannins were removed using polyamide columns and three fractions were collected for each. The extracts were also fractionated with Sephadex G-25, Amberlite IR 120 and Dowex 1-X8 as size exclusion, cation exchange and anion exchange, respectively. Extracts were also fractionated by preparative thin layer chromatography where two compounds were separated from S. frutescens extract with high activity against reverse transcriptase while showing insignificant inhibition towards other enzymes tested. SFL-BFW-10 and SFL-WEF-7 inhibited reverse transcriptase by almost 100 percent and the IC50 values calculated for these compounds were 0.34 and 0.23mg/ml, respectively. Cytotoxicity of these compounds was evaluated on Chang liver cells and peripheral blood mononuclear cells (PBMCs). None of these compounds showed any significant inhibition of cell proliferation. The purity of these compounds could not be confirmed because there was insufficient material to use in the techniques required to show purity and identification. Therefore, TLC was used to determine the nature of these compounds. SFL-BFW-10 was identified as an organic acid and SFL-WEF-7 was identified as flavonoid.

Endozoochory in the subtropical thicket: comparing effects of species with different digestive systems on seed fate

- Description: Endozoochory is an important form of seed dispersal and as such plays a fundamental role in plant population and community ecology. This is especially true in the Subtropical Thicket biome where many plant species are adapted for endozoochory. Endozoochorous seed dispersal is carried out by a wide range of thicket fauna, but changes in the faunal assemblage associated with transformed thicket threatens to disrupt the process of endozoochorous seed dispersal and in turn the regeneration dynamics of thicket plants. Outside of conservation areas, indigenous seed dispersers are often replaced by domestic species, such as goats, which are hypothesized to differ in their seed dispersal efficiencies. The dispersal efficiencies of important thicket seed dispersers that occur in transformed and untransformed thicket were therefore investigated. The influence of gut morphologyphysiology on seed gut passage time, seed mortality and germination in animal species representing different digestive models was measured, as well as the role of black-backed jackal in thicket plant seed dispersal. Black-backed jackal were found to disperse the seeds of few thicket plant species and are therefore not considered important thicket seed dispersers under the climatic conditions prevailing during the study. The average gut passage time of seeds was found to differ significantly between birds and mammals, but not between elephants (hindgut fermentor), goats (ruminant) and pigs (omnivore, foregut fermentor) as was expected considering the differences in their digestive morphology. A significantly shorter gut passage of large seeds compared with small seeds was observed in goats, due to the regurgitation of larger seeds. Seed regurgitation in ruminants may prove to be an important factor contributing to their quality as seed dispersers in transformed thicket. The mortality of seeds was significantly higher in goats than in elephants, probably due to the efficient digestion associated with ruminants. The effect of gut passage on seed germination was not consistent and varied between animal species and across different thicket plant species. It was concluded that seed dispersers that occur in transformed and untransformed thicket differ in their seed dispersal efficiency due, in part, to differences in the nature of their digestive tracts. This has important implications for the process of seed dispersal in thicket, and the rehabilitation of degraded thicket vegetation.

- Description: This study deals with African neo-traditional choral music of sub-Saharan- and Southern Africa, with specific reference to extemporisation. The research focussed on the evolution of this music through an amalgamation of western choral music and African indigenous and traditional musical practices of sub- Saharan and Southern Africa. Specific reference to the syncretism of western music, which came to Africa through colonisation, and the way African indigenous musical traditions influenced it, is preceded by descriptions on African indigenous musical practices and western choral music traditions. The incorporation of traditional folk songs into African makwaya, or “choir music”, was inevitable. This development saw the birth of African neotraditional choral music as a formal part of many choirs’ programmes. A description of five sample choirs engaging with this music was followed by a case study on the Drakensberg Boys’ Choir. The way these choirs deal with different aspects regarding the preparation and performance of this music highlighted many parallels with African indigenous traditions. It also emphasises the important role of this music in choral performance, as well as choral education. As a genre in evolution, one aspect of this music, namely extemporisation, was studied in more detail in order to suggest another way of engaging with this music. Not only is choral extemporisation a possibility in African neo-traditional choral music of Southern Africa, but it is also a flourishing art form in Scandinavia. In Norway and Sweden it also utilises characteristics and techniques of folk music, which raised the status of this music to be a major art form. This notion prompted the suggested application of choral extemporisation to African neo-traditional choral music of Southern Africa. Even if any method of extemporisation may be utilised, it is proposed that characteristics of African sub- Saharan- and Southern African indigenous music be applied. This may result in the incorporation of more of these African indigenous elements in the neo-traditional choral music discussed than the current western harmonic emphasis. However, the suggestion is seen as a next step in the evolution of this music, which corresponds with international practices, and not to return to indigenous practices as such.

- Description: This thesis presents a history of the landscape of Nqabara, an administrative area in a rural and coastal area of the Eastern Cape Province, South Africa. In the process of investigating landscape history, the inquiry engages with a range of data sources from diverging discursive contexts, including data from ethnographic fieldwork, from the consultation of archival documents and historical reports as well as from comparative historic and ethnographic research, necessitating a critical consideration of the epistemological contexts of data production and the dialogue between researcher and data. Furthermore, in its aim to move beyond historical description towards explanation, the study interrogates the dualist ontological conceptualisations of nature and culture, society and ecology, object and meaning upon which are built three dominant conceptual frameworks concerned with human-environment relationships: social-ecological systems theory, transdisciplinary landscape studies and political ecology. Drawing primarily upon the works of James Gibson, Anthony Giddens and Tim Ingold, an ontological foundation is developed to guide the enquiry and move towards an alternative understanding of the relationship of people’s livelihoods with respect to the landscape in which it is lived, which I call here the praxisembodiment perspective. This ontology takes the situated patterns of action of a situated agent-in-its-environment as its point of departure and proceeds to develop a framework explaining how relations among the patterns of action of different agents-in-their-environment, emerge in structures that simultaneously enable and constrain future action. The foundation is thereby provided for a monist understanding of how landscape and social structure emerge simultaneously from the complex intersection of patterns of actions and interactions of agents in their environment. This framework calls for an understanding of time, space and scale, not as independent variables influencing process and action, but as emergent properties arising from the patterns of actions of situated agents. Finally the alternative ontology is applied to the history of landscape and livelihoods of people of Nqabara. It is concluded that an appropriate understanding and explanation of the critical transformations in the landscape as well as in social institutions, should be sought through analysis of the complex ways in which patterns of action of multiple spatial and temporal rhythms and between multiple agents in an environment, intersect and resonate.

- Description: This thesis presents a history of the landscape of Nqabara, an administrative area in a rural and coastal area of the Eastern Cape Province, South Africa. In the process of investigating landscape history, the inquiry engages with a range of data sources from diverging discursive contexts, including data from ethnographic fieldwork, from the consultation of archival documents and historical reports as well as from comparative historic and ethnographic research, necessitating a critical consideration of the epistemological contexts of data production and the dialogue between researcher and data. Furthermore, in its aim to move beyond historical description towards explanation, the study interrogates the dualist ontological conceptualisations of nature and culture, society and ecology, object and meaning upon which are built three dominant conceptual frameworks concerned with human-environment relationships: social-ecological systems theory, transdisciplinary landscape studies and political ecology. Drawing primarily upon the works of James Gibson, Anthony Giddens and Tim Ingold, an ontological foundation is developed to guide the enquiry and move towards an alternative understanding of the relationship of people’s livelihoods with respect to the landscape in which it is lived, which I call here the praxisembodiment perspective. This ontology takes the situated patterns of action of a situated agent-in-its-environment as its point of departure and proceeds to develop a framework explaining how relations among the patterns of action of different agents-in-their-environment, emerge in structures that simultaneously enable and constrain future action. The foundation is thereby provided for a monist understanding of how landscape and social structure emerge simultaneously from the complex intersection of patterns of actions and interactions of agents in their environment. This framework calls for an understanding of time, space and scale, not as independent variables influencing process and action, but as emergent properties arising from the patterns of actions of situated agents. Finally the alternative ontology is applied to the history of landscape and livelihoods of people of Nqabara. It is concluded that an appropriate understanding and explanation of the critical transformations in the landscape as well as in social institutions, should be sought through analysis of the complex ways in which patterns of action of multiple spatial and temporal rhythms and between multiple agents in an environment, intersect and resonate.

- Description: The question of subjecthood has dogged linguistic science since ancient times. However, in current versions of Minimalism, subjects do not have primitive status and can only be defined in derived terms. However, subjects and the broader theoretical notion of SUBJECT remain important in linguistic description. This paper develops a definition of subjecthood in terms of set-theoretic notions of functional dependency: when a feature, say phi, determines the value of some other feature, say u-phi. This notion is used to describe various phenomena where subjecthood has been invoked: binding domains and subject-oriented anaphors.

- Description: Engineering pest resistance into crops is important. However, the mechanisms of resistance are not clearly understood. In this study, we examined the effects of aphid feeding on Russian wheat aphid-resistant and -susceptible cultivars of wheat (Triticum aestivum L.); Betta-Dn and Betta, respectively, by the grass aphid, Sitobion yakini (Eastop). These cultivars were grown with or without aphid colonies. In each case, we examined the plants specifically for the formation of wound callose associated with the phloem, using aniline blue and fluorescence microscopy. We observed that aphid feeding stimulated the formation of wound callose in the susceptible cultivar, but that callose was comparatively reduced in the resistant cultivar of wheat. In a separate series of experiments, the xenobiotic, 5, 6-carboxyfluorescein diacetate was applied to attached sink leaves, distal to feeding aphids. When leaf segments were examined four hours after application, little evidence of phloem transport of the fluorescent cleavage product, 5, 6-carboxyfluorescein (5, 6-CF), was evident below known aphid-probed sieve tubes. Low levels or absence of 5, 6-CF indicates that either the aphids have successfully redirected sap to themselves, or that the phloem is no longer functional. In contrast, 5, 6-CF transport was evident below sites of aphid probing in Betta-Dn, suggesting that the phloem was still capable of long-distance transport. In addition, callose deposition was reduced in Betta-Dn leaf phloem and it is surmised that transport was not as affected by aphid feeding in the resistant cultivar. This indicates that the ‘resistant’ wheat cultivar may in fact be tolerant to aphid feeding by successfully overcoming the nutrient drain that feeding aphids imposed on the phloem transport system.

- Description: Pelargonium reniforme is currently divided into two subspecies, P. reniforme subsp. reniforme and P. reniforme subsp. velutinum. The species falls into section Reniformia along with the closely-related P. sidoides. Observations of the section showed some discrepancies in the current taxonomy; mainly floral variation that was not recorded in the descriptions of the subspecies of P. reniforme, particularly the differences in hypanthium lengths. Patterns of variability were analysed using both morphometrics and inter simple sequence repeat (ISSR) data for P. reniforme (both subspecies), and P. sidoides. Results showed no support for the current subspecific division of P. reniforme but also no support for the current status of P. sidoides as a separate species. However, both morphometric and ISSR data show some evidence for the existence of two distinctly separate groups within P. reniforl1le subsp. velutinum as two distinct types have been recognized: those with bright pink flowers with long tubes (up to 70mm), and those with pale pink flowers with shorter tubes (as little as 8mm). These two forms have been found in a single population (Grahamstown), where they occur sympatrically, as well as in monomorphic populations. Analyses of the processes thought to be responsible for the observed patterns were conducted on the Grahamstown population. Observations of pollinators suggest that long-tongued insects (Butterflies, Nemestrinid flies) pollinate the long-tubed flowers and short-tongued insects (Bombyliid flies, long-tongued bees) pollinate short-tubed flowers. However, analysis of selection gradients in the population, indicate no directional selection is occurring for hypanthium lengths. The results of this thesis show that selection is occurring within Pelargonium reniforme, but at this time, selection is not strongly directional and floral differences are maintained, even when floral forms occur sympatrically. It is suggested that a review of the taxonomy be undertaken as well as additional pollination and selection studies to confirm suspected taxonomic groupings and relationships between the floral forms respectively. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Leadership and planning requires more strategic thinkers on all management levels in an organization. Historically, senior management does not effectively identify those leaders that posses the core traits and competencies to adequately influence the corporate culture by way of transformational and visionary leadership styles, so that it is aligned to the long-term strategy. In this research the author first embarked on a theoretical study into leadership and the associated contingency models, which have lead to the emergence of new styles of leadership, such as transformational, situational and visionary leadership. Thereafter, successful strategy planning and implementation was investigated to determine which leadership styles did the literature reveal are more conducive to successfully executing strategy in adaptive and culturally diverse corporate cultures. Thirdly, an empirical study was conducted to ascertain to what extent transformational and transactional leadership practices by South African firms are being adopted, and the amount of emphasis placed on the strategic thinking process between the leadership styles. Lastly, the data was analysed to explain the relationship between transformational and transactional leadership and strategic planning, and to make recommendations based on the research.

- Description: Levels of diabetic care in primary health care settings in South Africa have been found to be sub-optimal. Knowledge deficits and inadequate practices have been implicated in the poor quality of local diabetes care. Type 2 diabetes and hypertension are commonly associated chronic conditions hence to optimise diabetic care, tight control of blood pressure is essential. Although guidelines for the overall management of diabetes in a primary health care setting have been published (Working Group of the National Diabetes Advisory Board, 1997; Society for Endocrinology, Metabolism and Diabetes of South Africa, 2002a), adherence to these guidelines has not yet been optimised in the primary health care setting. The objectives of the study were: to design and implement an educational intervention aimed at nursing staff, based on the South African guidelines for type 2 diabetes and hypertension, at a public sector primary health care clinic; to determine the impact of the educational intervention on the level of knowledge and attitudes of the nursing staff, and on the level of diabetic and blood pressure control achieved in the patient population, and to determine the impact of the educational intervention on pharmacological management of patients. A questionnaire was used to quantitatively assess the nursing staffs’ knowledge of the management of type 2 diabetes and hypertension at a primary health care level. A qualitative evaluation of the nursing staff attitudes was obtained using focus group interviews. The educational intervention, in the form of lectures and based on national diabetes and hypertension guidelines (Working Group of the National Diabetes Advisory Board, 1997; Society for Endocrinology, Metabolism and Diabetes of South Africa, 2002a; Milne et al., 2003), was then implemented and directed at the nursing staff at a primary health care clinic. A post-intervention evaluation was performed after four months by repeating the questionnaire and focus group interviews. Comparisons between the pre- and post-intervention questionnaire and focus group interviews evaluated the impact of the educational intervention on the knowledge and attitudes of nursing staff towards the management of type 2 diabetes. Pre- and post-intervention patient data was collected from patient medical files and compared to determine if the management of diabetes and hypertension improved in the patient population after the implementation of the educational intervention. The patient population consisted of 103 patients. The educational intervention resulted in an extremely significant improvement in the level of knowledge of the nursing staff [93 correct responses (28.3 percent; n = 329 (pre-intervention)) vs 223 correct responses (67.8 percent; n = 329 (post-intervention)); p < 0.0001, Fisher’s Exact test]. The educational intervention resulted in improved attitudes of nursing staff towards the management of diabetes. Ideal random blood glucose concentrations improved significantly [16 percent; n = 100 (pre-intervention) vs 22 percent; n = 100 (post-intervention); p = 0.0003; Student t test]. The number of patients with a compromised HbA1c level (> 8 percent) decreased by 2 [51; 49.5 percent, n = 103 (pre-intervention) vs 49, 47.5 percent, n = 103 (post-intervention)] which was not a significant improvement. Ideal blood pressure control improved by one from 38 patients [36.9 percent; n = 103 (pre-intervention)] to 39 patients [37.9 percent; n = 103 (post-intervention)] which was not significant. Optimal change of pharmacological management following the referral of an uncontrolled diabetic patient was only noted for 18 patients (20.2 percent, n = 89) referred in the post-intervention phase. Clinical inertia was identified as a major limitation to the optimisation of diabetes care. Implementation of an educational intervention based on the South African diabetes and hypertension guidelines at a public sector primary health care clinic was successful in improving the knowledge levels and attitudes of nursing staff

- Description: Crucial to effective fisheries management is a thorough understanding of the stock structure of a population. Understanding the spatial and seasonal distribution patterns of a species is necessary to define habitat use and evaluate the potential effects of exploitation and anthropogenic activities. This is particularly important for a species such as the raggedtooth shark (Carcharias Taurus Rafinesque, 1810), whose life-history characteristics make it particularly susceptible to over-exploitation (Pollard et al. 1996; Smith et al. 1998; Compagno 2001). Exploitation, even at low levels for a slow-growing, late-maturing species that only produces two pups every other year, could reduce the population growth rate, could reduce the population growth rate to values of λ<1.0, resulting in severe population declines in a very short time period (Baum et al. 2003).

- Description: This thesis, entitled “An analysis of bank risk management and its relevance for the non-bank corporate sector”, investigates the extent to which financial risk management by the banking sector can be applied to the non-bank corporate sector. As banks’ risk management techniques are more sophisticated than those of the non-bank corporate sector we have endeavoured to ascertain the applicability of these established risk management methods to the non-bank corporate sector. The main objectives of this study were to analyse the banking sectors’ risks and management thereof, and compare them to the risks faced by the nonbank corporate sector. This analysis was then used to present a theoretical financial risk management model for the corporate sector. This analysis was conducted using qualitative research. The thesis engaged in an in-depth investigation of financial risk management through a documentary, literature and media analysis. It was elucidated that not all companies face the same financial risks and therefore each company requires its own unique financial risk management model. Furthermore, it was established that there are several risks that both banks and non-bank corporates are subjected to. However, the management of these risks is not necessarily the same for these two types of institutes. This thesis concludes by putting forward a financial risk management model which presents all the possible financial risks that non-bank corporates may face.

- Description: In 1985 the Diama Dam was built near the mouth of the Senegal River to regulate flows during the rainy season and prevent the intrusion of seawater during the dry season. This created ideal conditions upstream of the dam wall for invasion by two highly invasive aquatic weeds, first by water lettuce Pistia stratiotes Linnaeus (Araceae) in 1993, and then by salvinia Salvinia molesta D.S. Mitchell (Salviniaceae) in 1999. This study was focused on the management of P. stratiotes and S. molesta. Following successes that were achieved elsewhere in the world, biological control programmes involving two weevil species were inaugurated against both weeds and research was focused on several aspects. These included pre-release studies to determine the weevils' host-specificity and impact on the plants in the laboratory, their subsequent mass-rearing and releases at selected sites and post-release evaluations on their impact on the weed populations in the field. Both programmes, which reprepresented the first biocontrol efforts against aquatic weeds in Senegal, proved highly successful with severe damage inflicted on the weed populations and complete control achieved within a relatively short time span. A laboratory exclusion experiment with N. affinis on P. stratiotes showed that in treated tubs, the weevil strongly depressed plant performance as measured by the plant growth parameters: mass, rosette diameter, root length, number of leaves and daughter plants whereas control plants were healthy. Field releases started in September 1994 and water coverage by P. stratiotes at Lake Guiers was reduced by 25% in January 1995 and 50% in April 1995. A general decline of 65% in water coverage by P. stratiotes was observed in June 1995 and by August 1995, eight months after releases P. stratiotes mats were destroyed. Further, although no releases were made there, good results were obtained within 18 months at Djoudj Park water bodies, located 150 km NW from Lake Guiers indicating the potential of the weevil to disperse long distances. In 2005, P. stratiotes reappeared and the weevil N. affinis has located and controlled all of these P. stratiotes recurrences after new releases. In 1999, S. molesta covered an estimated area of 18 000 ha on the Senegal River Left Bank and tributaries (Senegal) and 7 840 ha on the Senegal River Right Bank (Mauritania). Military and Civil Development Committee (CCMAD) and community volunteers made an effort to control S. molesta using physical removal, but this costly and labour-intensive approach was unsustainable. Hence, biological control was adopted by Senegal and Mauritania to manage the weed. Host range tests to assess feeding by C. salviniae on S. molesta and non-target plants and carried out on 13 crop species showed that no feeding damage was observed on the latter and weevils only fed on S. molesta. Field releases of some 48 953 weevils at 270 sites were made from early January 2002 to August 2002. Within one year, weevils were established and were being recovered up to 50 km from the release sites. In a case study conducted at one of the release sites, the S. molesta infestation was reduced from 100% to less than 3% 24 months after release. These results are discussed in the context of the weeds’ negative impact on aquatic systems and riverside communities, and in the involvement of these communities in the programmes.

- Description: In 1985 the Diama Dam was built near the mouth of the Senegal River to regulate flows during the rainy season and prevent the intrusion of seawater during the dry season. This created ideal conditions upstream of the dam wall for invasion by two highly invasive aquatic weeds, first by water lettuce Pistia stratiotes Linnaeus (Araceae) in 1993, and then by salvinia Salvinia molesta D.S. Mitchell (Salviniaceae) in 1999. This study was focused on the management of P. stratiotes and S. molesta. Following successes that were achieved elsewhere in the world, biological control programmes involving two weevil species were inaugurated against both weeds and research was focused on several aspects. These included pre-release studies to determine the weevils' host-specificity and impact on the plants in the laboratory, their subsequent mass-rearing and releases at selected sites and post-release evaluations on their impact on the weed populations in the field. Both programmes, which reprepresented the first biocontrol efforts against aquatic weeds in Senegal, proved highly successful with severe damage inflicted on the weed populations and complete control achieved within a relatively short time span. A laboratory exclusion experiment with N. affinis on P. stratiotes showed that in treated tubs, the weevil strongly depressed plant performance as measured by the plant growth parameters: mass, rosette diameter, root length, number of leaves and daughter plants whereas control plants were healthy. Field releases started in September 1994 and water coverage by P. stratiotes at Lake Guiers was reduced by 25% in January 1995 and 50% in April 1995. A general decline of 65% in water coverage by P. stratiotes was observed in June 1995 and by August 1995, eight months after releases P. stratiotes mats were destroyed. Further, although no releases were made there, good results were obtained within 18 months at Djoudj Park water bodies, located 150 km NW from Lake Guiers indicating the potential of the weevil to disperse long distances. In 2005, P. stratiotes reappeared and the weevil N. affinis has located and controlled all of these P. stratiotes recurrences after new releases.

- Description: A common issue in leadership development is the high flyers who reach a position where their lack of “soft” skills hampers their performance and proves a barrier to their continued progression to higher levels of responsibility (Newell, 2002: 288). Business Schools offering Masters in Business Administration (MBA) programmes assist in developing managers with not just managerial competence but also with “soft” skills. By delivering educated business managers, these managers through their intellectual skills and community sensitive values, will lead future transformational processes. It is useful and interesting to consider how important emotional intelligence is for effective performance at work. A considerable body of research suggests that an employee’s ability to perceive, identify, and manage emotion provides the basis for the kinds of social and emotional competencies that are important for success in almost any position. Furthermore, as the pace of change increases and the world of work make ever-greater demands on an employee’s cognitive, emotional, and physical resources, this particular set of abilities will become increasingly important (Cherniss, 2000). The primary objective of this study is to determine the perceptions of the Masters in Business Administration (MBA), B-Tech in Business Administration (BBA), Advanced Business Programme (ABP) programmes and the Business School Alumni to determine the overall emotional intelligence profile of students as well as the effective team functions of the syndicate groups. Based on the main findings of the survey, it was concluded that emotional intelligence is an important factor for the NMMU Business School, MBA Unit students. The skills attained through the course work will not only improve team effectiveness in the syndicate group functioning but also enhance their performance in the business environment. The MBA team learning experiences enhances workplace learning as the ability to work in a team and ability to think and act independently are highly desired skills and competencies for success in the workplace.

- Description: The importance of wild edible herbaceous species to resource poor households in most rural economies within savannas has been little studied. This is because most of the herbs grow in impoverished species communities and lands, often referred to as ‘marginal lands’. The aim of this paper is to conceptualize how the economics of wild edible herbs to households can be used to add value to total livelihoods and conservation within traditional communal areas of South Africa. Analysis of the economics of the consumption of wild edible herbs in Thorndale (Bushbuckridge district) of the Limpopo province is presented. The majority of households consumed wild edible herbs, averaging 15.4 kg dried weight per household per year and valued at $167 per household. The herbs were mostly harvested from uncultivated areas of farms, and rangelands. There was little correlation between household characteristics and the dependence on wild herbs for food. The local people noted a decline in the availability of the species, although not much is known about attempts to cultivate them. The only reasons attributed to the decline were nutrient poor soils and insufficient rains. With this background, developing a local strategy to sustain the species through cultivation by households was found to be feasible. A multiple-use system for the herbs, their improvement and value addition towards commercialization and increased household usage may result in wider acceptance and subsequent cultivation. Species diversity will be enhanced whilst conserving the land on which they grow. This multiple use system may include species roles in soil and water conservation.

- Description: Many companies have performance management systems that incorporate financial and non-financial measurements. All organisations have financial and non-financial measures. However, many use their non-financial measures for local improvements at their front-line and customer-facing operations. Performance management is a shared process between managers and the individuals and teams they manage. It is based on the agreement of objectives, knowledge, skill and competence requirements and work and development plans. The Balanced Scorecard includes financial measures that reflect the results of actions already taken, complementing the financial measures with operational measures on customer satisfaction, internal processes, and the organisations innovative and improvement activities. The Balanced Scorecard combines both quantitative and qualitative measures, acknowledge the expectations of different stakeholders and relate an assessment of performance to choice of strategy. The objective of this study was to assess current performance management that is applied within the manufacturing division at Continental Tyre South Africa. To achieve this objective, a comprehensive literature study was performed on performance management and The Balanced Scorecard. A questionnaire was designed based on the guidelines in the literature study in order to establish the extent to which Continental Tyre South Africa manages performance. The researcher used the random sampling method of selection and distributed the questionnaire to 120 potential respondents via electronic mail and physically. Seventy seven completed questionnaires were returned and these were processed and analysed using Microsoft Office Excel 2003, iii running on the Windows XP suite of computer packages. The opinions of the various respondents were compared with the guidelines provided in the literature survey in order to identify shortcomings of performance management and the achievement of individual and departmental objectives within the manufacturing division at Continental Tyre South Africa. The following main recommendations were made: Continental Tyre South Africa should continue with the sharing of its strategic objectives with management and staff, and must ensure that these objectives are also shared all the way down to the shop floor; It is imperative that management and staff mutually agree on performance objectives for the individuals; Senior management must measure management and staff on how well they performance manage their direct reports and develop people where performance short-comings exist; It is imperative that management and staff undergo performance management training; Management must ensure that there current performance management system incorporates a method to distinguish between top and poor performers; and, It is advisable that senior management consider a mechanism that rewards top performers.

- Description: Learning takes place in a number of ways. Situated learning for example, tries to shift the focus from the individual as a learner to the learner participating in the social world and from learning as a strictly cognitive process to a more encompassing view of social practice. The overall aim of this research was to gain a deeper understanding of the ways in which learning takes place in and between members of a citrus farming community, in other words it was to investigate the social learning processes. The research was undertaken in Patensie, a citrus farming community of the Gamtoos River Valley, Eastern Cape, South Africa. Data was generated through the use of interviews and informal discussions with participants together with document analysis, such as minutes of meetings. I also made observations of the learning interactions that were evident and also the interactions that were evident in the area as a whole. The data was analysed in two phases, the first involved reading across the interview transcripts and organizing the data under broad themes while the second phase made use of an analytical framework, a Community of Practice perspective to further analyze and engage with the data. I drew quite strongly on the ideas of situated learning, Communities of Practice and the notion of Legitimate Peripheral Participation (Lave & Wenger, 1991) as a means to understand, interpret and describe the social learning processes. The research highlighted that in this case study, citrus farmers learn in a number of sociological ways, for example through intergenerational learning (in the family), learning from each other in a Community of Practice, learning from private consultants and extensions officers as well as from other organizations and institutions. It also considered how farmers' learning had influenced land use practice in the area. This brought to the fore an emerging partnership with a conservation agent based on providing economic incentives to farmers to engage in sustainable landuse practices. It is hoped that this research may inform future educational endeavours by shedding light on the social learning processes and by drawing attention to key aspects of learning that may previously have been overlooked in research.
