Description: The following dissertation considers the ways in which we have come to perceive of our post-apartheid South African urban spaces. It focusses on the representation of our contemporary urban spaces as I posit that they are re-imagined in the works of Phaswane Mpe, K.Sello Duiker, Nadine Gordimer and Lauren Beukes. In particular, it is concerned with the representation of Johannesburg, and specifically Hillbrow, in relation to the space of the rural, the suburban enclave and the city of Cape Town. I argue that while so-called urban ‘slums’ such as Hillbrow have been denigrated in the local imaginary, the texts that I have selected draw attention to the potentialities of such spaces. Rather than aspiring to ‘First World’ aesthetics of modernity then, we might come to see such spaces as Hillbrow anew, and even to learn from them as models, so as to better create more fully integrated and dynamic African cities.

Description: This study was carried out to document the ethno-veterinary plants and non-plant remedies that farmers used to control dermatophilosis and ticks, and validate these in vitro and in vivo, as well as determine how the interface of Amblyomma variegatum and A. hebraeum affected the epidemiology of bovine dermatophilosis at selected small-holder areas in North-West Zimbabwe. A structured questionnaire survey was used to collect information on the control methods used by farmers for the control of bovine dermatophilosis and ticks. A total of 39 plants were used by farmers for various diseases, eleven of these plants were used for the control of dermatophilosis while three were for tick control. Across the study sites, dermatophilosis was controlled using eleven plants. Among these plants; six plants; Cissus quadrangularis, Catunaregan spinosa, Pterocarpus angolensis Carica papaya, Manihot esculenta and Blumea decurrens which were frequently used were selected for further studies. In vitro and in vivo studies were conducted to validate the efficacy of these plants. The minimum inhibitory concentration and bactericidal concentration assays were used for the in vitro validation of C. quadrangularis, C. spinosa and P. angolensis. Dermatophilus congolensis was more sensitive to P. angolensis average MIC = 0.63 mg/ml than to C. quadrangularis average MIC = iii 1.25 mg/ml and C. spinosa average MIC = 2.08 mg/ml. Cissus quadrangularis was selected for in vivo studies as this plant was the one most frequently used by farmers. Its therapeutic efficacy was compared to conventional antibiotics that farmers used to treat dermatophilosis infection. In the in vivo trials C. quadrangularis did not lead to appreciable reduction in clinical disease compared to the conventional drugs. The larval packet assay was the in vitro assay used to validate the efficacy of Carica papaya, Manihot esculenta and Blumea decurrens against larvae of A. hebraeum and Rhipicephalus appendiculatus. Manihot esculenta at 20 % w/v exhibited the highest larvicidal activity against R. appendiculatus. In the in vivo study, efficacy of the plants were investigated on naturally tick-infested cattle. Mannihot esculenta exhibited the largest tick load reduction compared to the other two plants but its performance was lower than that of conventional acaricides. The effect of A. variegatum and A. hebraeum on bovine dermatophilosis was investigated by evaluating how the presence or absence of these ticks and other herd level risk factors predicted clinical dermatophilosis and its prevalence at herd level. A structured questionnaire survey was carried out to collect data on potential risk factors. At the same time, cattle were physically examined for the presence of bovine dermatophilosis, according to a pre-defined case definition, and presence or absence of Amblyomma ticks was also recorded. The multivariable binary logistic model was developed with disease status as outcome, tick presence and infestion and herd level risk factors as predictors. Of the herds examined clinical bovine dermatophilosis was detected in 45% (84/185; 95% CI: 38.2, 52.6%) of them. Herds infested with Amblyomma variegatum were associated with higher odds (OR= 6.8; iv 95% CI: 1.71, 27.10) of clinical dermatophilosis while the association was not significant (P > 0.05) in A. hebraeum infested herds. It was concluded that management practices aimed at movement and tick control would help reduce the prevalence of clinical dermatophilosis in herds.

Description: This study was carried out to determine alternative approaches used by resource-limited farmers to enhance fertility and in the treatment of reproduction ailments of goats in Mount Frere area, Eastern Cape Province of South Africa. Furthermore, information on farmer perceptions pertaining to these practices was also gathered. A questionnaire survey was conducted to determine materials used by resource-limited farmers to enhance fertility and treat reproductive ailments. The survey revealed 10 plant species that were commonly used for reproductive health in goats. Elephantorrhizza elephantina (37.1%) and Rhoicissus tomentosa (25.7%) were the most frequently cited plant species. Elephantorrhiza elephantina and R. tomentosa recorded the highest Fidelity Level (FL) values of 92.86% and 75% respectively, for their use in the treatment of reproductive ailments and these were the plants on which further studies were conducted. The study also revealed that farmers had different perceptions on the effectiveness of the traditional medicines. An in-vivo assessment was done to determine efficacy of E. elephantina and R. tomentosa using serum estradiol and progesterone profiles. The highest (P<0.05) serum estradiol and progesterone concentration was observed in animals administered with aqueous extracts of E. elephantina and R. tomentosa mixture while the least (P<0.05) concentrations were observed in the negative control group. Does administered with a mixture of aqueous E. elephantina and R. tomentosa extract had the highest (P<0.05) body weight (65 kg) as well as body condition scores, while the negative control which were administered with distilled water had the least body weights (54 kg) and body condition scores. Does that were administered with a mixture of E.elephantina and R. tomentosa were all pregnant with twins (100%), confirmed by a doppler ultrasound scan.

Description: The measurement of economic performance and social development has become increasingly important as societies have evolved and become more complex. At present nations do not only seek to improve economic performance but are also compelled to improve social development through improvements in socially and environmentally sustainable initiatives. Traditional measures such as Gross Domestic Product (GDP) which is derived from United Nations’ System of National Accounts (SNA) have been criticised given the inability to adequately account for these social and environmental aspects of social development. Given these perceived deficiencies in the conventional measures, several alternative objective measures have been proposed in an attempt to address these shortcomings. Therefore the primary aim of this study is to analyse, via a literature survey, these alternative objective measures of economic performance and social development. The alternative measures that constitute the survey are the Index of Sustainable Economic Welfare (ISEW), the Genuine Savings (GS), and the United Nations’ Human Development Index (HDI). Upon the completion of the literature survey, sustainable development theory is used to evaluate the extent to which the National Accounts and the alternative objective measures are consistent with Hicksian and Fisherian definitions of income and capital, which embody the concepts of sustainability and sustainable development. The evaluation reveals that the National Accounts neither conform to the Hicksian nor the Fisherian definitions of income, thus could not be viewed as a measure of sustainable income. It is found that the ISEW is consistent with the Fisherian definition of income and is also a partial indicator of sustainable development. The evaluation of the GS measure reveals that it is consistent with the Hicksian definition but not the Fisherian definition. In terms of overall sustainability, it is argued that GS is a partial measure of weak sustainability. The HDI is similar to the National Accounts, in that it is neither consistent with the Hicksian nor the Fisherian definitions of income and is also not a measure of sustainability. In summary, the study demonstrates that despite GDP's shortcomings as a measure of economic performance and social development, currently, there is no alternative approach which simultaneously addresses every flaw in GDP. However, all the alternatives yield a much better approximation of social development than GDP.

Description: The South African public sector is important for the sustainable growth and development of the country. One of its major responsibilities is to ensure that all citizens have access to and receive the services they need. The manner in which public sector institutions are structured has an impact on the delivery of effective and efficient services to citizens.Achieving a high degree of productivity is an important objective of public service organisations across the world given the pressure to deliver quality public goods and services within the limits of ever-increasing resource constraints. The South African Public Service is no exception to this global phenomenon. The focus on the public service is therefore continuously to improve performance to meet citizens’ needs. Where as performance is directed at measuring outputs achieved, productivity goes an important step further by measuring the relationship between the resources used to achieve outputs. The focus of this study is the analysis of change and transformation strategies in the Department of Home Affairs, Province of the Eastern Cape. The primary purpose was to assess the current state of service delivery in the Department of Home Affairs and to ascertain how continuous monitoring and evaluation could be factored in to enhance the delivery of services. The target population was the employees and clients of the Department of Home Affairs. Employees were selected randomly and asked to participate in the study. The sample was a convenient-purposive sampling and a quantitative research questionnaire was used.

Description: This study investigates the Zimbabwean women listeners of a gender-focused radio programme Nguva yevanhukadzi (Time for Women) to find out what meanings they take from the programme. Located within the broad theoretical framework of cultural studies and drawing on audience reception theories, the study focuses on the ways in which Shona-speaking women bring their understandings of their social roles, derived from their lived socio-cultural experiences of patriarchy, to their decoding of the text. The study was set in Harare’s high-density suburb of Mbare and used the qualitative research methods of individual and focus group interviews. The study was conducted against the backdrop of the signing of the Global Political Agreement (GPA) of September 2008, which ended the impasse among the warring political parties, ZANU PF, MDC-T and MDC and introduced a new era of collectively tackling socio-economic development, including redressing gender disparities through women’s empowerment. This study examines the factors shaping the audiences’ readings of the programme and seeks to establish whether the mass media has determining power on its audience in the reception of messages or if the audiences (women) have interpretive freedom. Using Hall’s (1980) Encoding/ Decoding model, the study examines the factors that influence the audiences’ choice in making preferred, negotiated or oppositional readings and the arguments they advance in line with those readings. While the interviews revealed that most of the female listeners “negotiated” the dominant encoded meanings, seeking their relevance to their varied situations and contexts (O’ Sullivan et al. 1994:152; Ang 1990: 159), of interest is the manner in which the women dealt with the discourse of patriarchy within the context of promoting women empowerment. The contestation between women empowerment and addressing patriarchy reflected the subverted notions of maintaining the status quo, while applauding the women’s commitment and ability to interrogate the practicality of issues under discussion and drawing lessons relevant to their day to day lives prior to making the preferred reading. As such, the study revealed that preferred readings are not always automated, but can be a result of intense interrogation among media audiences.

Description: With global advances in technology, many organizations are finding it difficult and quite challenging to do business as usual. Japanese companies are on top of the world economy, while many Western companies are struggling to find ways to compete with them (Womack, et al., 1990). The Japanese secret weapon “Lean Production” is no longer a secret; more and more western companies are now learning and adopting Lean techniques to remain relevant and competitive. Lean management is a consistent philosophy and a set of practices that must be maintained over time in order to see the gains (Losonci & Demeter, 2013). Lean is not a quick fix to reduce costs, but a continuous improvement journey that will transform an organization into a cost efficient value-driven system. Lean is still a fairly new phenomenon in South Africa, particularly in the Eastern Cape. The road towards the lean implementation is viewed by many as a challenging and yet rewarding journey. South African organizations are following the trend of implementing lean in order to eliminate waste, improve quality, speed, customer satisfaction and thereby increasing profits. It is however still a long journey towards achieving total perfection. The main challenge facing South African organizations is the ability to sustain the lean improvements over a longer period. This study will focus on identifying and analyzing the main barriers that inhibit many successful organizations from sustaining lean improvement efforts.

Description: The aim of this study is to develop an understanding of how Grahamstown teenagers are affected by the label ʹdyslexiaʹ; by providing a space in which their feelings about being labelled dyslexic and their experiences can be voiced. Historically much international and local research has focussed on causation and remediation of dyslexia and has neglected the social aspects of the diagnosis. Causation and remediation are categories which form part of the medical or educational models. A social model of dyslexia needs to be applied. Due to the paucity of South African literature on the social experiences of dyslexic teenagers, this research thesis aims to add to the body of knowledge and hopefully provide an avenue for more research within the context of Sociology. This is a micro study, situated in Grahamstown Eastern Cape, South Africa, and the author recognizes that responses cannot be generalized to the greater dyslexic population. All human environments consist of objects which are given meaning through social interaction. Meaning is central to human behaviour and therefor explains the ways in which humans conduct their lives based on these meanings. For this reason George Herbert Mead’s (1934) and Herbert Blumers (1969) symbolic interactionist positions have framed the theoretical approach to this research. Qualitative methods of interviewing provide an opportunity for dyslexic individuals to discuss the meaning dyslexia gives to them, from their perspective and in their own words. The following conclusions have been arrived at: Educational psychologists in Grahamstown are reticent to diagnose individuals as dyslexic. This lack of identification hinders early intervention which can be very detrimental to individuals struggling with reading, writing and spelling as well as the associated co-morbid conditions of dyslexia. Teenagers who have had early diagnosis and intervention with support structures in place identify with their dyslexic identity more positively as they are able to make sense of their struggles of a dyslexic nature.

Description: Transnet is facing challenging market realities and a competitive operating environment. Performance management has been emphasised as a critical tool to guide Transnet in maintaining a competitive advantage. Performance management cannot be viewed in isolation from the organisational context and is inextricably linked to the Human Resources strategy, which in turn is aligned with the overall business strategy. Performance management may be defined as a systematic process by which an organisation involves its employees, as individuals and members of groups, in improving organisational effectiveness in the accomplishment of organisational mission and goals. For the purposes of this study, performance management was explored in terms of purpose, key role players, processes, criteria and challenges. The main research problem of this study was to determine the perceptions of non-bargaining unit employees of the performance management system at Transnet Engineering. The main research problem had three sub-problems which were addressed through the following actions: A literature study was conducted highlighting the importance of an effective performance management system which establishes a foundation for rewarding excellence by aligning individual objectives with organisational mission and objectives. In this way, performance management establishes clear expectations in terms of results, actions and behaviours. Through regular feedback and coaching, performance management provides a mechanism for detecting problems at an early stage and identifies ways in which to take corrective action. Perceptions of performance management are largely centred around fairness, and dependent on a number of issues, including openness, transparency, communication, and equitability, and the establishment of clear parameters of measurement such as whether both skill and effort will be evaluated. This is why it is important to link performance appraisals to employee goals. If mutually negotiated goals, which involve the participation of all stakeholders, are established at the beginning of the performance period and there is on-going feedback to employees about their performance, then performance appraisals may be perceived as objective, fair and reliable. The insights gained from the literature survey were incorporated into a survey questionnaire which was used in the empirical study to investigate the perceptions of non-bargaining unit employees of the performance management system at Transnet Engineering. This study revealed that most of the respondents were not satisfied with the performance management system within Transnet Engineering, that performance management could be enhanced by using multiple measures more frequently and that greater involvement of subordinates at each step in the performance management process would lead to a greater level of acceptance thereof.

Description: South Africa’s Labour Laws should undergo drastic changes in 2014 when new amendments take effect. The bills amend the Labour Relations Act 66 of 1995 (LRA), Basic Conditions of Employment Act 75 of 1997 (BCEA) and the Employment Equity Act 55 of 1998 (EEA). These amendments originate from the increasing “casualisation” of work prevalent in the South African Labour market and aim to address the phenomenon of labour broking, the continuous renewal of fixed-term contracts and unfair discrimination regarding wages amongst others. The legislature effected additional amendments to these Acts to align them with new developments, to improve the functioning of the Commission for Conciliation, Mediation and Arbitration (CCMA) and to fulfil South Africa’s obligation as a member of the International Labour Organisation (ILO). 1 In addition, the amendments attempt to clarify the wording of the Labour Relations Act (LRA) to elucidate numerous significant judicial interpretations of various provisions of the current Act as well as to close what some believe to be loopholes in current legislation. There are differing views on the possible effects the amendments could have on the country; some believe that it will damage business while others believe it will affect job creation. 3 According to Bosch, the amendments allow employers flexibility without depriving employees of rights properly due to them. 4 The researcher emphasises topical issues such as the need for temporary employment services, entitlement to organisational rights and the abuse of fixed-term contracts and further discusses, to a lesser extent and focusing on discrimination, the Basic Conditions of Employment Act5 (BCEA) and the Employment Equity Act6 (EEA).

An analysis of the relationship between bank efficiency and access to banking services in South Africa

Description: The primary objective of this study is to investigate the nature of the relationship between bank efficiency gains and access to banking services in South Africa. The importance of making such an enquiry arises from the fact that various studies have identified access to financial services as an important vehicle for lifting the poor out of poverty. In particular, there is concern that banks` appetite for better scores on efficiency has the potential of reducing access to services for consumers particularly the low-income clients. The study attempted to answer two central research questions: Firstly, does the quest for banks to improve efficiency preclude access to banking services for some group of consumers? Secondly, do bank efficiency gains necessarily translate to improved accessibility to banking services? The researcher applied a two-stage methodology approach. In the first stage, the Hicks-Moorsteen aggregator functions were used to generate and decompose total factor productivity (TFP) into several efficiency measures for a panel of eight South African banks. First stage results revealed that the average banking sector total factor productivity efficiency (TFPE) was 59 percent implying that the observed TFP was 41 percent short of the maximum TFP possible using the available technology. A further comparison of performance revealed that large banks were better performing than small banks in terms of TFPE. Apart from estimating and decomposing TFP indices we needed to determine if there was a statistically significant change in the TFPE of South African banking system as a result of the global financial crisis. A general analysis of the generated scores showed that TFPE clearly decreased during 2008-2009, the period that coincided with the global financial crisis. We then used the Fixed Effects Model (FEM) in the second-stage analysis to examine the link between banking sector TFPE and access. The FEM was utilised to take account of bankspecific heterogeneity. The obtained results indicated existence of a positive and significant relationship between banking efficiency and access to banking services. This study suggests that banking sector efficiency plays a crucial role in promoting access to bank services in South Africa. We therefore underscore the need for all banks to attain and maintain high efficiency in order to augment government efforts towards improving accessibility for the unbanked South African people. We also found evidence similar to that reached by Kablan (2010) that an increase in the rural population is associated with a reduction in access to bank services. From this result, we speculated that banks are somewhat biased against providing their services to the general rural populace. Since the rural-population variable exerted the greatest marginal impact on access we suggested that perhaps investment in rural infrastructure would help broaden access and so improve financial inclusion on a larger scale. Finally we also investigated the link between banking sector efficiency and unemployment in South Africa. Of paramount importance in the second stage analysis was that we found a negative and significant association between banking sector efficiency and unemployment indicating that employment is influenced, inter alia, by the efficiency with which banks operate.

Description: This research seeks to explain how students construct knowledge in introductory accounting. It was prompted by concerns over low pass rates for first-year Introductory Accounting students at Rhodes University and particularly low pass rates amongst novice (first-time) Accounting Students. In trying to get a better understanding of reasons behind these pass rates, this research focuses on the structure of knowledge in the discipline and what this means for how students should construct knowledge in the course. Bernstein’s Pedagogic Device and the dimensions of Semantics and Specialisation in Maton’s Legitimation Code Theory are used as theoretical and analytical frameworks to help understand the structure of knowledge in this course, how knowledge is recontextualised and finally how it is acquired by students. A group of students from the 2011 class were interviewed to gain a better understanding of how each of these students constructed knowledge during the semester. The analysis of these interviews reveals how students construct knowledge in the course and the implications this has for their success over the semester. Analysing this interview data, and comparing it with the levels of success for each student, permitted me to develop an improved understanding of how successful and unsuccessful students construct knowledge. As a teacher of Accounting, understanding and being explicit about the structure of knowledge in the discipline, and how this impacts on the construction of knowledge, will allow me to advise future students on how to most effectively construct knowledge in this course and to advise and guide colleagues on how best to present this course.

Description: The features and capacities of mobile devices offer a wide range of significant opportunities for providing learning content in workplaces and educational institutions. This new approach of teaching, called mobile learning, allows for the delivery of learning content on the move at any time. Mobile learning supports learning by producing learning content to learners in a modern and acceptable way. The number of mobile learning applications has increased rapidly in educational environments. There are, however, limited mobile learning applications that take advantage of mobile devices to support contact learning in the classroom environment. The aim of this research was to design a mobile learning architecture to effectively support contact learning in the classroom. The researcher investigated the historical and theoretical background of mobile learning and reported these findings. This included an overview of existing mobile learning architectures. After identifying their limitations, the researcher designed the Contact Instruction Mobile Learning Architecture (CIMLA) to facilitate the use of mobile devices in the classroom. The researcher developed the LiveLearning prototype based on the proposed architecture as a proof of concept. He conducted a usability evaluation in order to determine the usability of LiveLearning. The results indicated that the LiveLearning prototype is effective in supporting contact learning in the classroom.

Description: Evidence of mineral disequilibrium is presented for the Merensky Reef at Winnaarshoek in the eastern Bushveld Complex. Petrographic disequilibrium textures, disequilibrium in orthopyroxene, plagioclase and clinopyroxene mineral compositions as well as disequilibrium in Sm-Nd isotopic compositions of whole rock samples and coexisting plagioclase and orthopyroxene are presented. Disequilibrium textures presented include clinopyroxene exsolution lamellae in orthopyroxene; resorbed plagioclase in orthopyroxene or relict plagioclase; various inclusions such as orthopyroxene, plagioclase or clinopyroxene in larger oikocrysts of clinopyroxene or orthopyroxene; discontinuous rims of clinopyroxene surrounding orthopyroxene; resorbed orthopyroxene in clinopyroxene; and corona textures associated with olivine. These textures were used to derive a possible mineral crystallization sequence. At least two sequences of crystallization took place, both of which crystallized plagioclase first. One sequence then crystallized olivine which was then consumed to produce orthopyroxene which crystallized prior to late clinopyroxene. The other sequence indicates orthopyroxene crystallization after plagioclase crystallization, followed by crystallization of clinopyroxene. These sequences indicate at least two magmas were responsible for the genesis of the Merensky Reef and its hanging wall and footwall units. Compositionally, disequilibrium is evident in the range of compositions found in coexisting orthopyroxene, plagioclase and clinopyroxene with stratigraphic height, with particular reference to the change in mineral composition in each of the hanging wall, Reef and footwall units. Orthopyroxene compositions range in Mg numbers between 74.6 and 82.9 (77.4) in the hanging wall, 78.5 and 87.0 (avg. 81.1) in the Reef, and 77.9 and 84.1 (avg. 81.3) in the footwall. Plagioclase compositions range in An content between An64.9 and An82.3 (avg. An75.1) in the hanging wall, An56.8 to An70.8 (avg. An62.7) in the Reef, and An54.2 to An86.3 (avg. An73.2) in the footwall. In terms of Sm-Nd isotopic compositions, disequilibrium is evident between both whole rock samples and coexisting plagioclase and orthopyroxenes. Bulk rock Sm-Nd isotopic compositions show a range in ԐNd values between ԐNd (2.06 Ga) = -4.8 to -6.4 in the hangingwall, ԐNd (2.06 Ga) = -6.3 to -8.5 in the Reef, and ԐNd (2.06 Ga) = -4.5 to -6.3 in the footwall. Similar ԐNd values are present in the hanging wall and footwall units, with a clear “spike” in the Merensky Reef. ԐNd values in plagioclase are between ԐNd (2.06 Ga) = -5.8 and -7.8, while orthopyroxene isotopic Sm-Nd values are between ԐNd (2.06 Ga = -7.1 and -9.1. The mineral disequilibrium features presented within this study help elucidate the crystallization sequence of the magma as well as to constrain the contamination of the magma upon ascension and emplacement of the Merensky Reef. The results of this study favour a model where a mantle plume resulted in the ascent of a new magma which was contaminated by the assimilation of old, lower crust. Contamination took place prior to the possible lateral emplacement of the Merensky reef as a density current. 5-10% contamination of depleted mantle or a B2-“like” source by Archaean TTGs is modeled to achieve the contamination “spike” of ԐNd = -8.5 in the Merensky Reef.

Description: This research assesses the nature and extent of financial accountability on social grants at the South African Social Security Agency (SASSA). With respect to public funds, strategies and mechanisms, including the effectiveness of these strategies, were analysed to ensure whether SASSA was accountable to both the people and the government. Rabrenovic (2009:22) describes financial accountability as an obligation of the government to assure the citizens that money is spent in the best possible and most effective way. The government has to provide answers and justification for its action and regularly inform the public on how it spends the public funds. The extent to which the public-private partnership model adopted by SASSA for social grant management has enhanced financial accountability and yielded the desired outcome has also been tested. Some of the findings were that the problems facing SASSA were the financial constraints that entailed reduction in new programmes, halting infrastructures and the acquisition and filling only of funded posts from the Auditor General of South Africa (AGSA) and the high costs of administering social grants. This study used the qualitative research approach. The researcher used official document reviews because of the sensitivity of the research problem and opted for a desktop research. The documentary sources include SASSA’s annual reports for the period 2011/12. The recommendations were that people should be trained in financial and performance skills and in terms of accountability the accounting officers should account for lack of transgressions and poor performance.

Description: Human wildlife conflict is a considerable conservation challenge that threatens many carnivore species worldwide and is a result of complex socio-economic and ecological processes. An understanding of the drivers of conflict is essential for any efforts to achieve coexistence. This study investigated the levels of conflict, livestock management and tolerance amongst the farming communities of the Southern and Western Kalahari in Botswana. A questionnaire survey was completed with 310 farmers throughout the region. The majority of respondents regarded coexisting with carnivores as a challenge, with losses due to depredation perceived as the greatest problem facing farmers. Conflict was widespread throughout the study area, with some spatial variations for certain species. Cattle management levels were low and while smallstock management was better, the use of improved levels of management could reduce current levels of conflict. Tolerance levels were generally low with few respondents seeing the benefits of coexistence with carnivore species. The results indicated that farm type, gender, education level, source of income, livestock numbers, location and land use all have an effect on perceived conflict and tolerance levels and strongly interact with each other. In general cattleposts were characterised by higher proportions of females, lower education levels, more benefits derived from wildlife and veld products and fewer livestock than fenced ranches. They also experienced more conflict, carried out more management and had better tolerance levels. It could be that closer connections to the land and deriving benefits from natural resources resulted in more tolerance and this is certainly worth further investigation. An improvement in the use of effective methods of livestock management, targeted environmental education programs to develop a greater awareness for the conservation value of carnivores and a diversification of livelihoods to include benefits from natural resources have the potential to reduce conflict and improve tolerance in the Kalahari region.

Description: Prior to 1991, the development concept and strategy of Local Economic Development (LED) was not part of the development lexicon in South Africa. With the exception of some very limited local government advertising campaigns and the work of NGOs, the concept of locally –based and driven development interventions was an alien one in South African practice. The rigidities of the apartheid state, both in terms of its racial controls and its centralized management of all affairs precluded local development initiatives. What spatial economic development there was, focused on the flawed pre-1991 Regional Industrial Development Programme, which was tainted by failure to promote the former Homelands, corruption and faulty economic logic (Reflections on the Evolving Nature and Prospects of Local Economic Development in South Africa: 1990-2007). The post-apartheid government in its quest to alleviate poverty formulated a number of policies and legislation to guide developmental local government initiatives. Thus local government committed itself to, among others, building local economies and creating jobs for the people. By the end of Apartheid, South Africa’s economy was facing a variety of serious structural problems. The final two decades of the National Party’s regime had been particularly damaging to the economic climate, with stagnant economic growth (the average over the entire period was just 1.7%), declining per capita income (averaging -0.7% annually), increasing unemployment (using the broad definition, up from around 20% at the start of the 1970s to around 30% by 1994) and a spiraling debt problem (under the De Klerk government (1989-1994) alone, debt had increased from less than 3% of GDP to more than 9%, and total government debt more than doubled. Facing this “deep-seated structural crisis”, the government attempted to put together a policy framework that could begin to address the variety of problems being faced both economically and otherwise. The RDP White Paper, presented to Parliament in 1994, identified economic, social, legal, political, moral, cultural and environmental problems that the country faced.

Description: The intention of this study was to investigate how organisational change was implemented at S.P. Metal Forgings Uitenhage, what the outcomes of the changes were and the effect on the organisational culture. In order to achieve this goal, the following actions were taken: · A literature study was conducted of various texts relating to organizational change and the associated topics with the intention to identify strategies and techniques to aid the successful implementation of organisational change. · An interview was held with the managing director of S.P. Metal Forgings to aid in understanding the need for organisational change at this particular facility and to have insight into how he implemented the changes. · A self administered questionnaire was distributed amongst a number of employees. The survey covered all levels of the organisation, from machine operators to departmental managers, to provide a comprehensive picture of how the employees viewed the changes and associated topics. The questionnaire requested responses from the respondents regarding their demographical details and their individual opinions regarding the organisational change, which covered the lead up to the changes and the manner in which the changes were made. The questionnaire also included sections covering change outcomes, which measured the success of the change efforts and lastly organisational culture on site at the time of the study. The results from the literature study showed that there are a number of accepted change models which can be adopted when implementing change. These models assist in driving the organisational change. The empirical study revealed that for the changes implemented at S.P. Metal Forgings Uitenhage, a change model was not adopted and that a number of vitally important areas associated with the change efforts were inadequately addressed. The organisational changes were introduced on this particular site with the intention of minimizing the loss situation and re-establishing the organisation as a profit generating entity. The empirical study showed a number of positive outcomes associated with the changes but also highlighted areas of concern and points which can be improved. The culture found within an organisation influences the organisation in many ways which include the ability of the organisation to accept change and the ease of implementing new procedures and equipment. The culture also influences the daily operations of a manufacturing facility such as this one. The study revealed that the respondents are not driven to perform at their best as a result of the lack of recognition which they receive and that the relationship between employees and management can improve. It was concluded that organisational change is not easy to introduce and that it needs to be well planned and executed. Change requires transformational leaders, a clear vision, an analysis and well-thought out and properly implemented actions.
