- Description: This article reports a systematic clinical case study of the psychological assessment and treatment of Daniel (9), a coloured South African boy with a diagnosis of attention deficit hyperactivity disorder (ADHD) (inattentive type). The case is of scientific interest because: (1) there was only a single treatment session, in which contingency management training was delivered to Daniel’s parents and teacher; (2) there was evidence for the effectiveness of the intervention immediately and at two-year follow-up; (3) it documents the transportability to a South African context of an intervention developed by overseas research; (4) it documents the central role of case formulation in the delivery of effective psychological interventions; and (5) although Daniel met the criteria for ADHD, he also displayed symptoms of depression and social anxiety and the case supports the use of a transdiagnostic approach to case formulation. The conscientiousness with which his parents and teachers applied the programme was a major factor in the effectiveness of the intervention, and such rapid impact would not be possible where parents and teachers are unavailable or not co-operative. The publication of systematic case studies such as this one is important for the development of a local evidence-based practice in South Africa.

- Description: Weather has a significant impact on business activities of many kinds. The list of economic activities subjected to the risk of the weather include: the energy producers and consumers, the industry of leisure, the insurance industry, the food industry and the agricultural industries but the primary industry, namely the energy industry, has given rise to the demand for weather derivatives and has caused the weather risk management industry to evolve actively. A derivative is a contract or security, whose payoffs depend upon the price of an underlying asset price, and is used to control the risks of naturally-arising exposures to such an asset price. Therefore weather derivatives are financial contracts with payouts that depend on weather in some form. It is a contract that provides a payoff in response to an index level based on weather phenomena (West, 2002).The underlying variable can be for example humidity, rain, snowfall, temperature, or even sunshine. The main players who take part in the weather derivatives markets industry can be grouped in to five main categories, namely: 1) End users who are also referred to as hedgers 2) Speculators 3) Market makers 4) Brokers 5) Insurance and re-insurance companies. Since the late 90’s when the first weather derivatives transactions were recorded, the underlying market has witnessed the development of a new derivative market in the United States, which is gradually expanding across Europe. However, the newly developed market for weather derivatives is not liquid in Africa and specifically South Africa mainly due to the following factors: 1) Many companies and business organisations have not yet established a hedging policy or even figured out how their businesses or industries are exposed to weather risks. 2 2) “Since many companies and industries depend on insurance companies to cover their risks, it is possible that the solutions suggested by these companies or industries looking for protection from weather risks differ according to the cover provided by these insurance organisations “(Micali, 2008). The main aim of this study is to review available statistical models for pricing derivatives, with temperature as the underlying which could enable industries, businesses and other organisations in South Africa to protect themselves against losses due to fluctuations in the weather and therefore hedge their risks.

- Description: This study sought to investigate the relevance of Person-Environment (P-E) fit amongst Human Resource (HR) graduates from Nelson Mandela Metropolitan University (NMMU) within the Nelson Mandela Metropole (NMM). A secondary objective of this study was to determine whether P-E fit was a determinant of Human Resource (HR) graduates’ migration. The study comprised a pilot study and main study (n=50). The study was qualitative in nature, but incorporated a quantitative research component to support the qualitative research findings. Results showed that HR graduates from the NMMU perceived P-E fit as important. Immense emphasis was placed on achieving P-E fit by means of finding employment related to Human Resource Management (HRM). The lack of P-E fit, amongst HR graduates, was furthermore revealed as a determinant of graduate migration. HR graduates would relocate to pursue a career in HRM. Implications of the findings are that organisations should use the theoretical knowledge of HR graduates to develop their skills and broaden their practical knowledge. This will secure competent future HR managers for the NMM and help to combat scarce skills migrations from the area.

- Description: This research aims to open up for critical discussion the effects of the discourses employed by mental health professionals in relation to the diagnosis of BPO, with a view of questioning the discursive practices available within a South African context. This discussion will situate identified discourses in relation to the subjects and objects to which it refers in an attempt to identify and interrogate dominant discourses which circulate to oppress and discriminate against female 'others' within the mental health setting. This discussion will serve to challenge mainstream, traditional psychology by questioning the utility of deploying these concepts within a South African context as well as the effects this deployment may have. A discourse analytic methodology is employed to identify the constructions of BPO by five mental health professionals working within a government setting. The analysis aims at interrogating the broader role of the identified discourses in supporting institutions, preserving power relations and transmitting ideological practices. Ultimately the aim of the research is to open up for critical debate, through the example of psychology and psychiatry's treatment of BPO; constituted as 'other', the possibility that there may be deleterious consequences for the wholesale acceptance of traditional psychological understandings by mental health professionals working within a South African context. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: This special section of the Shakespearean International Yearbook asks a series of questions about South African Shakespeare, chapter by chapter, focusing on the twentieth century. The temporal emphasis is deliberate, because it was particularly in the last century that Shakespeare became an issue, albeit a minor one, in relation to the titanic political and ideological struggles that convulsed the country throughout the period. The articles set out to examine and re-assess, in historical sequence, some of the acknowledged highlights of Shakespeare in South Africa in the last century. These are the moments when, for a range of different reasons, Shakespeare troubles the public sphere to claim attention in excess of that normally accorded ‘routine Shakespeare,’ that haphazard succession of productions, tours, educational debates, academic publications, reviews and commentary that comprises the internal history of the subject.

- Description: Commonage is land that is usually found adjacent to a town, which is owned by the local municipality and acquired through state grants or, historically, through the church. Since the new government dispensation in 1994, poor and previously disadvantaged residents have acquired access rights to commonage for agricultural purposes. Through the Department of Land Affair’s Commonage Programme, local municipalities are acquiring more commonage land for purposes of agriculture and grazing livestock. Commonages are increasingly being recognised as an important livelihood asset for the poor and unemployed residents’ of towns and rapid urbanisation is contributing to the increasing use of commonage for livelihood provisioning. Some municipalities view commonage as a key asset to promote Local Economic Development, while others are finding it difficult to manage the land effectively, to the extent that some analysts see tragic ecological consequences occurring due to over-grazing. This has been likened to the “tragedy of the commons” as advocated by Hardin in 1968. Commonage and common property resource systems have many similarities and co-management has been advocated as a potential management regime for commonage. Researching the policy framework, institutional structures and management bodies involved in commonage, gave a better understanding of the governance and management of the commonages in Grahamstown, Fort Beaufort and Bathurst. Current management attempts are not ensuring the efficient, equitable and sustainable use of these commonages. The governance framework is not adequately supporting proper management. In an environment of resource-poor institutional bodies, adaptive co-management could prove to be the most effective system to ensure the sustainable use and development of this natural resource. Furthermore, commonage is no longer contributing to the Land Reform Programme. Commonage should be better integrated into agrarian reform through lease schemes and an efficient Emerging Farmer Programme.

- Description: The main goals in electroanalytical sensing are towards improved sensitivity and selectivity, or specificity, of an analyte. There are several approaches to achieving these goals with the main approach being modification of an electrode surface with synthetic or natural catalysts (enzymes), polymers and also utilisation of nanostructured materials. At present, there is a strong movement towards hybrid sensing which couple different properties of two or more surface modification approaches. In this thesis, a range of these surface modifications were explored for analysis and detection of two main analytes: the amino acid, tryptophan (Trp); and, the neurotransmitter, dopamine (DA). Specifically, this thesis aimed to utilise these methods to enhance the sensitivity and selectivity for Trp over an interferent, the indoleamine, melatonin (Mel); and, DA over the vitamin, ascorbic acid (AA). For Trp detection, immobilisation of an enzyme, Tryptophanase (Trpase) resulted in poor selectivity for the analyte. However, enhanced sensitivity and selectivity was achieved through pH manipulation of the electrolyte medium at a Nafion®-modified electrode surface for both Trp and Mel. At pH 3.0, the Mel and Trp anodic peak potentials were sufficiently resolved allowing for an LOD of 1.60 and 1.62 nM,respectively, and permitting the accurate analysis of Trp in a dietary supplement containing Mel. Multi-walled carbon nanotubes (MWCNTs) suspended in Nafion® exhibited further increases in the signal responses of these analytes at pH 3.0 and 7.4 with minimal change in the resolution of the anodic peaks. A lower sensitivity was, therefore, observed at the Nafion® and MWCNT modified electrode compared to the Nafion®-modified electrode at pH 3.0 with LODs of 0.59 and 0.80 nM exhibited for Trp and Mel, respectively. Enhanced selectivity for Trp in the presence of Mel can be achieved with MWCNTs in the presence of metallotetrasulphonated phthalocyanines (MTSPcs) particularly at pH 3.0, owing to cation exchange effects. However, the lack of sensitivity towards Trp, and even Mel, at this CoTSPc and MWCNT modified electrode remains a drawback. For DA, detection at the MWCNT and Nafion® surface resulted in improved sensitivity over that of both the bare electrode (613.0 nM) and the Nafion® modified electrode (1045.1 nM) with a calculated LOD of 133.9 nM at this layer. Furthermore, improvements in the selectivity of DA were achieved at the Nafion® and MWCNT modified electrode as exclusion of AA (150 μM) was achieved. At the MWCNT and CoTSPc surface, AA was excluded up to 130 μM with sensitivity for DA extending as low as 14.3 nM, far greater than observed for Trp and Mel. These concentrations are well within physiological concentration ranges and represent the most significant solution yet in terms of AA exclusion and enhanced sensitivity for DA. An examination of the surface layering by impedance spectroscopy and atomic force microscopy indicates that the success of the hybrid sensor utilising CoTSPc and MWCNTs lay in improved dispersion of MWCNTs and improved electron transfer kinetics, facilitated by the net charge of the materials present. This thesis, thus, showed the utility of a judicious selection of synthetic and biological catalysts, polymers and carbon nanomaterials towards a hybrid approach to the electrochemical sensing of Trp, Mel, DA and AA with focus on sensitivity and selectivity of these analytes.

- Description: This study investigated influence strategies used by university students to negotiate condom use. The study examined the seven condom influence strategies (CISs) -withholding sex, direct request, seduction, relationship conceptualizing, risk information, deception, and pregnancy prevention- used by heterosexually active male and female students. The sample comprised of 156 first year students (male=44 and female=112). Statistically significant correlations were found among all the condom influence strategies subscales. Results suggest that the university students influence their partners in all identified condom influence strategies and the risk information strategy holds the most promise of all the strategies.

- Description: Small towns internationally and in South Africa are becoming increasingly marginalised, and they are often experiencing economic downturn, demographic shifts and a rearticulation of their role in the urban hierarchy. In the case of South Africa many of these small towns are also faced with low levels of social development. The urgent need to address such conditions is evident by the fact that a large proportion of the South African population resides in small towns, and their surrounding hinterlands. This said, there are examples of small towns, internationally and in South Africa which, through the use of various Local Economic Development actions, have managed to remain sustainable, and in some cases become economically viable localities once again. In light of the above, the research conducted for this thesis seeks first to establish the socio-economic changes occurring over time in three small towns in the Eastern Cape Province of South Africa, namely Stutterheim, Bedford and Hamburg. Secondly, the research aims to identify the nature of LED activities in the three small towns, highlighting those factors contributing to the success of LED initiatives as well as those factors inhibiting LED in small towns. This is done with the intention of developing future lessons for LED in small towns. The research was conducted using a mix of qualitative and quantitative data generated through the interviews with key role players in each town, as well as secondary data sources. Findings from the research suggest that the small towns investigated are characterised by low levels of socio-economic development. In addition, it appears that the development opportunities for the towns are limited. Current initiatives are being driven by private role players with local government being largely uninvolved. Such initiatives are limited in nature, with benefits only felt by small groups of the local community. However, examples do exist of where LED has successfully benefited the broader spheres of the local community, thus suggesting that if implemented properly such an approach does have potential to assist in the socio-economic development of small towns. In light of this, a number of lessons are identified for LED in small towns, including the need for strong leadership, community involvement, partnerships between role players, and planning for project sustainability.

- Description: A basic ichthyofaunal and physico-chemical survey of the coastal outlets on the south coast of South Africa (Robberg Peninsula to Cape St Francis) was undertaken during November 1994 and September 1995. Some 27 systems were identified along this stretch of coast and of these, 48% (Brak, Helpmekaars, Klip, Witels, Geelhoutbos, Kleinbos, Bruglaagte, Langbos, Sanddrif, Eerste, Boskloof, Kaapsedrif and Klipdrif [Wes]) comprised the inlets of coastal streams that offer little habitat for fishes, 26% (Sout, Bloukrans, Lottering, Elandsbos, Storms, Elands and Groot [Oos]) are located within deeply incised valleys within the Tsitsikamma region and provide limited littoral habitat for estuary-associated fishes; 26% of the systems (Piesang, Keurbooms, Matjies, Groot [Wes], Tsitsikamma, Klipdrif [Oos], Slang) appear to serve some estuarine function for both marine migrant and resident species although some of these may also be limited due to their small size and infrequent connection with the sea. This study serves to emphasize the ecological importance of these latter estuaries within this coastal sector.

- Description: The metabolic disorder diabetes; is a global epidemic affecting people in developed countries and increasingly in developing countries. In two decades time, 350 million people will be diabetic at the current rate of prevalence. In a preliminary study, insulin resistant rats were treated with Prunus Africana (plant A) for 28 days. Plasma samples obtained from P. africana treated rats had increased insulin levels compared to normal and untreated insulin resistant rats (Karachi, 2009). The treatment of insulin resistant rats with P. africana also showed increased glucose uptake in rat adipose tissue (Karachi, 2009), suggesting that P. africana had anti-diabetic properties. The aim of the study was to investigate the mechanism of the anti-diabetic properties of P africana extract. Increased insulin secretion was confirmed by the increased Cpeptide concentration in plasma samples of rats treated with P. africana. In order to explain the high insulin levels, several hypothesis’ were investigated: (1) P. africana may increase insulin secretion in β cells, hence the effect of P. africana on insulin secretion by INS-1 cells was investigated; (2) P. africana may increase insulin secretion by prolonging the half-life of glucagon like peptide-1 (GLP-1) by decreasing dipeptidyl peptidase IV (DPP IV) activity; the effect of P. africana on DPP IV activity was determined spectrophotometrically, (3) P. africana may increase the half-life of insulin in the plasma by decreasing the activity of insulin degrading enzyme (IDE); the effect of P. africana on IDE in rat muscle and spleen samples was investigated. To explain the increased glucose uptake in adipose tissue observed in the previous study two parameters were investigated: (1) increased GLUT4 expression in P. africana treated rats; the effect of P. africana treatment on the expression of glucose transporter 4 (GLUT4) was determined using real-time polymerase chain reaction (RT-PCR), (2) P. africana may increase glucose utilization; the effect of P. africana on glucose utilization was determined in 3T3-L1 cells. The plant extract did not significantly increase insulin secretion by INS-1 cells in the absence of glucose. P. africana decreased DPP IV activity in rat plasma when compared to the untreated insulin resistant rats and this could be a mechanism by which insulin secretion is increased during plant treatment. P. africana decreased IDE activity (however not significantly) when compared to the untreated insulin resistant The effects of a Kenyan antidiabetic plant on insulin homeostasis KY Suleiman VII rats. P. africana appeared to have no effect on GLUT4 expression. The plant appeared to increase glucose utilization in 3T3-L1 cells in the absence of insulin suggesting that P. africana may have insulin like activity. In summary, this study indicates that P. africana is indirectly involved in inhibiting DDPIV. This in turn can increase the half life of GLP-1, which in turn can enhance the secretion of insulin. P. africana increases glucose utilization although there was no evidence that the GLUT 4 transporter has a higher expression in the plant treated rats. Further studies should be conducted to investigate the expression of GLUT1 under the same conditons.

The album included a music video of the title track that calls upon the legendary Boer War general to save the volk (people) from the wantonly destructive strategies of the British imperial forces: the scorched earth policy and the subsequent internment of women and children in concentration camps. The British justified such extreme – some would say ‘genocidal’ – strategies so as to prevent non-combatants from supporting the irregular Boer soldiers. Although he did not believe that the war could be won on account of the overwhelming odds that the Boer forces faced, De la Rey still fought to the bitter end. Needless to say, he was on the losing side.

- Description: The African continent has been hit the hardest by the HIV/AIDS epidemic which has seen more women becoming infected than men (Hunter, 2003; UNAIDS, 2004). This has been attributed to the permissible nature of the African culture which is lenient on male promiscuity (Foreman, 1999; Colvin 2000; Leclerc-Madlala 2001; Dube 2003). African women are not only vulnerable to infection but are also vulnerable to negative disclosure experiences when they disclose their status to sexual partners. This double impact of culture has not been addressed by past researches (UNAIDS 2004). The present research thus attempts to fill that gap. It explores the interplay between culture and HIV transmission as well as the interplay between culture and disclosure experiences. The study’s setting is Magunje Township, a rural village in Mashonaland Central province in Zimbabwe. Taking into consideration the limitations of the present analysis, data gathered indicates that African women are vulnerable to both HIV infection and negative disclosure experiences. Their vulnerability also hampers prevention and treatment efforts as it makes them decide to keep their status a secret from sexual partners for fear of losing the financial income tied to sexual partners. The present researcher concludes with some suggestions for policy makers and programme implementers, highlighting the importance of focusing on HIV/AIDS status disclosure as a prevention and treatment method in the absence of a cure for HIV.

- Description: This study investigates the extent to which South African short-term insurance companies manage climate change risk, as evidenced in their annual and sustainability reporting. The study context takes into account the fact that the world’s climate has been changing at a more accelerated rate since the early 1970s, causing disasters that have negatively affected world economies in the last ten years. Insurers, due to their huge financial resource base, long history of spurring innovation around risk and encouraging loss-reducing behaviour as well as high levels of vulnerability, have been identified as one industry that could lead societies in finding solutions to climate change risk. A key element of such a corporate resolve involves taking a leadership position which makes business sense for insurers. As such, this research analyses how innovative solutions to change-related problems could result in reduced exposure to climate change in line with corporate triple bottom line objectives. Based on a purposive sampling of short-term insurance companies operating in the South African market during the 2007 financial year, the study uses the companies’ annual and sustainability reports in order to critically assess evidence of climate change-related performance. The assessment is undertaken against the best practice indicators of climate change risk management, as defined by Ceres – a global researcher on climate change management in the business context. The data analysis is largely qualitative, consisting of a narrative presentation of the results and a conceptual application of the results to the triple bottom line which forms the theoretical framework of this study. The study finds that the South African short-term insurers were generally not living up to the climate change management ideals, in comparison to their multinational counterparts. For the South African short-term insurers, corporate strategic product innovation and planning was insignificant. Also negligible was board involvement, as well as CEO involvement, though in at least one case of the 4 local short-term insurance, there was evidence of extensive CEO involvement in climate change risk management. On the whole, these findings represent a lapse in corporate governance inasmuch as climate change risk management is concerned. Local short-term insurers generally performed well in the area of public disclosure, with their scores ranging from insignificant to extensive. In contrast, multinational short-term insurers’ performance with regard to climate change risk intervention ranged from insignificant tointegrated, across the five governance areas of board oversight, management execution, public disclosure, emissions accounting and strategic planning. As such, the study broadly recommends that short-term insurers in South Africa should make climate change part of their overall risk management strategies in order for them to remain competitive in an environment of increased climate change-related risk. More specifically, the research project recommends that the local insurers should proactively lead climate change mitigation measures through, for instance, investing in clean energy projects and incentivising their clients’ participation in the carbon market to prepare themselves for possible regulatory restrictions after the Copenhagen climate change conference planned for December 2009. This study also challenges insurers to help communities and as well as other businesses in their value chain to reduce their negative impacts on the world’s climate and to be more resilient against disasters which may arise from the high levels of greenhouse gases already in the atmosphere. Further, it recommends that insurers should create internal board and executive level climate change-related structures, as these will facilitate the integration of the proposed initiatives into their overall sustainability strategies. Above all, the study recommends that insurers should enhance the reporting of their climate change-related risk, opportunities and initiatives to improve their integrity.

- Description: Syntheses, spectral, electrochemical and spectroelectrochemical studies of phenylthio and amino derivatised metallophthalocyanines complexes are reported. The complexes are immobilized onto a gold macro disk, gold ultramicroelectrode and gold coated fiber electrodes via self assembly with phenylthio MPc derivatives or onto a glassy carbon electrode via electropolymerisation with amino MPc derivatives. For the first time MPc SAMs were formed on gold coated fiber. The electrocatalytic behavior of the modified electrodes was studied for the detection of nitrite and L-cysteine, all modified electrodes showed improved electrocatalytic oxidation compared to the unmodified electrode. The MPc complexes catalyzed nitrite oxidation via a two-electron mechanism producing nitrate. Cobalt tetraaminophthalocyanine showed the best catalytic activity for nitrite oxidation in terms of overpotential lowering compared to other complexes and thus was used for nitrite detection in a food sample, the nitrite concentration was determined to be 59.13 ppm, well within the limit for cured meat products. Electrocatalytic oxidation of L-cysteine on SAM modified gold coated fiber was reported for the first time. The gold coated fiber and ultamicro cylinder electrode were less stable towards the electro-oxidation of cysteine compared to its oxidation on the gold disk. The gold disk electrode gave better catalytic performance in terms of stability and reduction of overpotential. The phenylthio cobalt phthalocyanine derivative gave the best catalytic activity for L-cysteine oxidation in terms of overpotential lowering compared to other phenylthio derivatized MPc complexes. The amount of L-cysteine in human urine was 2.4 mM, well within the urinary L-cysteine excretion range for a healthy human being.

- Description: The dynamic social and economic conditions in Namibia warranted a periodic review of labour legislation. Given these needs, uhe then Ministry of Labour, undertook a project in 1998, to assess the effectiveness of the first post kndependence Labour Act, 1992 (Act No 6 of 1992) a trirartite task force was established which recommended the amendment of the 1992 Act. This led to the enactment of the Labour Act, 2004 which introduced a new system of dispute prevention and resolution. However, the 2004 Act could not be put into effect in its entirety, because of its technical flaws and the fact that the Namibian Employers Federation (NEF) took issue with some of the provisions of the Act, such as leave provisions. In 2005, the Ministry of Labour and Social Welfare with its social partners undertook a complete technical review of the entire 2004 Act. As a result, In 2007, the new Labour Bill 2007 was tabled in Parliament, which eventually adopted it as the Labour Act, 2007 (Act No 11 of 2007) which became operational on the 1st November 2008. The new Labour Act, 2007 (Act No 11 of 2007) brings in sweeping changes to the familiar terrain of labour law and industrial relations practice in Namibia. The new Act, has done aware with the District Labour Court system, in its place comes the Labour Commissioner. The rudimentary dispute- settlement mechanisms of the old (first ) Labour Act, 1992 ( Act No 6 of 1992) have made way for the more sophisticated, yet speedier and more economical system of alternative dispute resolution through arbitration and conciliation by the Labour Commissioner. The Labour Act, 2007, requires parties to the labour dispute to seek conciliation before either taking industrial action or seeking adjudicative solutions to the dispute. Not only does the Labour Act, establish or makes provision for the appointment of the Labour Commissioner to provide for dispute resolution, it also permits parties to establish their own process for dispute resolution through a private arbitration route. Faced with this daunting array of untested rules and institutions, I have approached the writing of this work with some trepidation. My aim is to provide a thoroughgoing commentary on the provisions relating to dispute resolution. In the absence of much authoritative interpretation, I had to rely heavily on past practices and foreign South African precedents to identify the construction that judges and arbitrators are likely to arrive at. The present treatise provides a, comprehensive and integrated commentary for all involvement in the resolution of labour disputes in Namibia; it further provides rules and procedures which govern statutory disputes resolution through the Labour Commissioner. I sincerely hope that this paper, will prove useful to all those involved in labour law and industrial relations practice, as well as to teachers and students of this subject.

- Description: The morale of educators in certain schools is very low. From the literature review I concluded that not all schools experience low morale in the same way. There are different factors impacting on the morale of educators at different schools. In this study, the causes of low educator morale, indicators of low morale, the importance of high morale and how low morale can be dealt with were addressed in order to provide guidelines to improve low morale. An empirical study was conducted and 2 schools in the Northern Areas of Port Elizabeth were used in this case study to establish to what measure the educators are exposed to the abovementioned variables. The data was analysed qualitatively and quantitatively. South Africa is divided into different demographic areas. The majority of people living in the communities where these schools are located are poor, unskilled, unemployed and the crime levels are very high. The socio-economic context within which these schools are located also has an impact on the morale of the educators at these schools and it affects their working lives. Educators, SMTs and principals took part in the empirical study so that their views can be compared and to facilitate the researcher to make recommendations on improving low educator morale. The research outcomes were analysed and deductions, recommendations and a need for further research were given. The empirical and literature study emphasised that the morale of educators is low in the schools and this morale status impacts on learners’ achievements, the health of the educators and the health of the institution. The educators in this study ranked their own morale status as low and some of the causes of the low morale according to the empirical study are lack of resources, ill-disciplined learners, uninvolved parents and an ineffective management style of the principal.

- Description: South Africa’s land redistribution policy (1994-2008) has been widely publicised, and has come under scrutiny of late from the public, private and government spheres, highlighting a need for research in this area. The research examines progress in South Africa’s land redistribution programme in two of KwaZulu-Natal’s district municipalities, Uthungulu and iLembe. Specifically the research investigates whether the government has paid above market prices when purchasing sugarcane farmland for redistribution in these districts. Moreover, it is illustrated how productivity on redistributed farms has been affected with the changes in ownership. To investigate the research questions, reviews of theories pertaining to property rights, land reform and market structures were conducted. Moreover, two cases studies were conducted in the districts of Uthungulu and iLembe, with assistance from the Department of Land Affairs, Inkezo Land Company and the South African Cane Growers Association. The case study data indicate that above ordinary market prices have been paid (2004-2006) by the government for sugarcane farmland in the districts concerned, and further that productivity has been negatively impacted ‘during’ and ‘post‘ transfer, in the majority of cases.
