- Description: Analog audio needs a separate physical circuit for each channel. Each microphone in a studio or on a stage, for example, must have its own circuit back to the mixer. Routing of the signals is inflexible. Digital audio is frequently wired in a similar way to analog. Although several channels can share a single physical circuit ( e. g., up to 64 with AES10 ), thus reducing the number of cores needed in a cable. Routing of signals is still inflexible and any change to the equipment in a location is liable to require new cabling. Networks allow much more flexibility. Any piece of equipment plugged into the network is able to communicate with any other. However, installers of audio networks need to be aware of a number of issues that affect audio signals but are not important for data networks and are not addressed by current IT networking technologies such as IP. This white paper examines these issues and provides guidance to installers and users that can help them build successful networked systems.

- Description: African Potato (Hypoxis hemerocallidea), (AP) is an African traditional medicine (TM) that is commonly used for various nutritional/medicinal purposes and also by people infected with the human immuno deficiency virus HIV and AIDS patients as an immune booster. The use of AP has also been recommended by the former Minister of Health of South Africa for use by HIV positive people. The main phytochemical component of AP is a norlignan glucoside, hypoxoside, and other relatively minor components have also been reported. A recent in vitro study reported the effects of AP extracts, hypoxoside and rooperol (the metabolite of hypoxoside) on human metabolic enzymes such as the cytochrome P450 (CYP450) group of enzymes and also on the transporter protein, p-glycoprotein (P-gp). This research focussed on investigating the clinical significance of those in vitro effects on the pharmacokinetics of efavirenz (EFV) in humans. EFV was chosen as the substrate drug because it is in first-line regimen of treatment of HIV/AIDS in South Africa, and also has been reported to be a substrate for the specific CYP isozymes, 3A4 and 2B6, in common with APs metabolic involvement with 3A4. A high performance liquid chromatography method with ultra-violet detection (HPLC-UV) for the quantitative determination of EFV in plasma was developed and successfully validated according to international standards with good reproducibility, accuracy, recovery, linear response and requisite sensitivity. The preparation of the plasma samples for analysis was effected by using a simple and rapid precipitation method, and the mobile phase consisted of readily available solvents. EFV in plasma samples was found to be stable under the relevant storage conditions studied. The oral dose of AP, administered as a freshly prepared traditional decoction, was standardised based on the hypoxoside content, and the quality of all the AP decoctions was analysed immediately prior to administration, using a validated HPLC-UV method. A single dose, two-phase sequential study was conducted over a period of 31 days in 10 healthy volunteers. The clinical study was approved by the Rhodes University Ethical Standards Committee, and all the participants agreed to the conditions of the study by giving their informed consent. On day 1 of the study, human subjects were administered a 600 mg EFV tablet and blood samples were collected before dosing and at various intervals over a period of 48 hr post dosing. From day 16, a traditionally prepared AP decoction was administered daily at a standardized dose of 15 mg/kg/day per subject until day 30. On day 29, volunteers were administered a single 600 mg dose of EFV as was done on day 1. Plasma samples were harvested immediately after blood sample collection and frozen at -80 ºC until assayed. Geometric mean ratios of relevant pharmacokinetic parameters, Cmax (maximum plasma concentration achieved following dosing) and AUC0-48 (area under the curve of a plot of drug plasma concentrations versus time representing the extent of absorption) of EFV before and after co-administration of 14 successive daily doses of AP were compared and evaluated to determine whether an interaction had occurred. All subjects completed the study and the geometric mean ratios of Cmax and AUC0-48 were 97.30 and 102.82 with corresponding 90% confidence intervals (CIs) of 78.81-120.14% and 89.04-118.80%, respectively. Whereas the acceptance criteria for the ratios of the AUCs fell within the preset 90% CIs indicating no interaction, the Cmax ratios fell outside the limits. Although the protocol was developed in accordance with the United States of America Food & Drug Administration’s Guidance for Drug Interactions, a priori stating that both criteria need to fall within the acceptance limits to indicate no interaction, an argument is presented to waive the Cmax requirement for the declaration of an interaction. As a result, the pharmacokinetic data generated during this study indicated that the effect of AP on the pharmacokinetics of EFV is not clinically significant. Hence, co-administration of AP is unlikely to affect the clinical use of EFV. In summary the objectives of this project were: 1. To develop and validate a suitable HPLC-UV method for the quantitative determination of EFV in plasma. 2. To perform a mini-validation of the determination of hypoxoside for use as a marker in the quality control and standardisation of AP decoctions. 3. To conduct a clinical interaction study in order to determine whether AP affects the pharmacokinetics of EFV following concurrent administration. 4. To apply the validated HPLC-UV method to determine plasma concentrations of EFV in plasma of human subjects. 5. To use appropriate statistical methods and treatments such as a non-compartmental pharmacokinetic analysis to determine the occurrence of an interaction.

- Description: The Heritage Game has an ambitious aim: to persuade those engaged in heritage management that economists have a valuable contribution to make and that they should be allowed to join the table where decisions are made—not as occasional “hired guns” consulting on specific matters, but as routine and continuous contributors to the discussion. As such, the book explains and illuminates some of the fundamental ideas in economics (consumer sovereignty, moral hazard, incentives, opportunity cost) as applied to the “heritage biz”. It is written in a light-hearted style that fulfils the authors’ intention of “making economics palatable and even enjoyable … offering both instruction and entertainment” (p. 10). Even economists familiar with the field will thus find it a pleasurable read, filled as it is with humorous anecdotes and examples drawn from the authors’ personal experiences as contributors to heritage management and policy.

- Description: Fleas are one of the major external parasites affecting free range chickens, causing irritation, tissue damage, blood loss and toxicosis which in turn affect quality and quantity of meat and egg production. There are many commercial insecticides available that are effective against fleas. These commercial insecticides have, however become expensive to most resourcelimited farmers and therefore unaffordable, causing farmers to seek low cost alternatives. This study was conducted to document, determine the existence of external parasites in freerange chickens and validate the alternative remedies used in controlling free-range chicken fleas by resource-limited farmers. A questionnaire survey was used to collect data on external parasites of free-range chickens and ethno-veterinary control remedies used by resourcelimited farmers to control these parasites at Amatola basin, in Eastern Cape, South Africa. Resource-limited farmers perceived that mites (79.6%), fleas (64.5%), lice (10.8%) and ticks (6.5%) were problematic parasites of chickens. To control these parasites, resource-limited farmers commonly use ash (28%) madubula (13% carbolic acid) (26.7%), Jeyes fluid (13% carbolic acid) (10%), paraffin (8.4%), used engine oil (2.8%), plants Tagetes minuta, Clutia pulchella, Calpurnia aurea (5.2%) and a few (4.2%) used commercial drugs Karbadust (Carbarly 5%) and mercaptothion 5%. About 7.5% of the respondents used neither of the remedies. To confirm the farmers’ perception on problematic external parasites of free-range chickens a diagnostic survey was conducted. Fifty free-range chickens were randomly selected and examined for external parasites. About 96% of the free-range chickens examined harboured at least one species of external parasites. Fleas (Echidnophaga gallinacea) (50.7%) were the most prevalent followed by lice, Menopon gallinae (12.4%); Menacanthus stramineus (5.3%) and Knemidocoptes mutans (0.57%). Given that Jeyes fluid, used engine oil, paraffin, C. aurea, C. pulchella and T. minuta were mainly used in controlling these parasites, it was important to determine the potential dermal irritant effects of these plants. A dermal irritant effect test was, therefore, conducted using a rat model. Forty eight rats, with parts of the backs shaven, were used to screen the materials for irritation. All the materials tested did not cause any visible skin irritation on rats (p>0.05). Regarding that ethnoveterinary materials were non irritant on rat skin in vitro repellency and contact bio-assay models were used to assess the insecticidal properties of Tagetes minuta, Calpurnia aurea, Clutia pulchella, used engine oil, paraffin and Jeyes fluid on fleas. For the in vitro bioassay T. minuta and Jeyes fluid at 100% concentration demonstrated a repellency level of 76 and 83%, respectively. Tagetes minuta was the most effective among plant materials (p<0.05). Clutia pulchella, C. aurea, used engine oil and paraffin showed insignificant repellency (p>0.05). For the contact bio-assay, C. pulchella, C. aurea and T. minuta at a concentration of 100% resulted in flea mortality of 83.5, 73.3 and 42.5%, respectively. The efficacy of Clutia pulchella compared well with that of Karbadust which had a mean mortality of 97.5%. Paraffin, used engine oil, and Jeyes fluid (19.2%) caused higher flea mortality of more than 82%. In the in vivo study 60 free-range chickens were artificially infested with fleas and test materials were topically applied on infested sites. Test materials exhibited varying flea load reduction efficacy. Used engine oil and Jeyes fluid at 76.8% concentration had a reduction efficacy of 100 and 96% after 3 days post application of test materials. These were not significantly different to that of the positive control Kabadust (carbaryl 5%). The plants C. pulchella and C aurea at 100% concentration had an efficacy of 92 and 77%, respectively. The commonly used remedies by resource-limited farmers to control fleas vary in efficacy. Some of the materials are as effective as the commercial insecticides hence they have a potential to be exploited as insecticides. Further investigations on plant compounds with insecticidal properties and their toxicity, need to be conducted before the plants are recommended for use.

- Description: [From Introduction] Some of the poorest rural people in South Africa are turning to the natural resource base for income generation. Using traditional skills they are converting a variety of wild resources into commodities that are sold in the market place. Wood and woven craft, medicines, fresh and processed wild foods, alcoholic beverages, building materials, fuelwood, dried mopane worms, cultural artefacts and brooms are just some examples of the array of natural resource products increasingly seen for sale in local and external markets. Many of the participants in this trade have minimal education, few assets to draw on, and little access to alternative sources of income or jobs. A significant proportion are women, with more than half heading their own households. Many come from households devastated by HIV/AIDS. The cash earned from selling natural resource products, however modest, is of critical importance to the households involved, preventing them from slipping deeper into poverty. “Since I have been making brooms my children no longer go to bed crying of hunger” observed one broom producer. NGOs, particularly those involved in rural development, can play an important role in assisting producers overcome some of the obstacles they face and in enhancing the opportunities to grow this informal sector. , This policy brief is based on the original brief made available for a workshop in August 2006. It draws on, amongst other sources, the results of several case studies of natural resource commercialisation undertaken across South Africa. The project was funded by the South Africa-Netherlands Programme on Alternatives in Development (SANPAD), BP South Africa and the National Research Foundation (NRF). The Center for International Forestry Research, with support from SIDA, provided the funding to share these findings with key stakeholders including government policy and decision makers.

- Description: This paper investigates the relationship between the logical distance between two IP addresses on the Internet, and the number of packets captured by a network telescope listening on a network containing one of the addresses. The need for the computation of a manageable measure of quantification of this distance is presented, as an alterna-tive to the raw difference that can be computed between two addresses using their Integer representations. A number of graphical analysis tools and techniques are presented to aid in this analysis. Findings are pre-sented based on a long baseline data set collected at Rhodes Universi-ty over the last three years, using a dedicated Class C (256 IP address) sensor network, and comprising 19 million packets. Of this total, 27% by packet volume originate within the same natural class A network as the telescope, and as such can be seen to be logically close to the collector network.

- Description: Literature on effectiveness indicates the interest of researchers in the role that teams play within organisations. The conclusion is that different variables affect team performance effectiveness. A further analysis of literature on team effectiveness enabled the researcher to develop a matrix of assessment of team effectiveness from these variables to serve as a benchmark. In addition to this, a matrix consisting of perceived variables of team effectiveness was constructed from the outcome of in-depth interviews and focus group sessions with the members of management committees of community-based organisations (CBOs) based within Port Elizabeth townships. These matrixes were used by the researcher to assess the operationalisation of these variables within the CBO management committees. The research indicates that management committees either did not operationalise these variables within their teams or did not do so to their fullest capacity. The overall outcome of these assessments indicates the areas that require attention, and provides opportunity for group practitioners to assist CBO management committees to enhance their effectiveness as teams. It is suggested that group practitioners together with members of CBO management committees, embark as a task team project to develop a strategy to refine the perceived variables guided by those emphasised by experts within this field, to strategise a clear path towards enhanced team effectiveness.

- Description: On 27 December, 2007, Kenyan citizens took to the polls for the fourth time since multiparty democracy was introduced in 1992. The sentiment was that democracy was finally coming of age in this East African country. For many, these elections represented a turn in the country’s democratic process that would bring change in the areas of justice, food, shelter, education and employment to all – as these were the main campaign promises. Instead, at the conclusion of the voting and at the beginning of the tallying process, the electorate erupted violently at the suspicion and eventual reporting of the process being rigged. One of the main subjects discussed in this study includes the argument that Kenya is ailing from a lack of responsible political leadership. The breed of Kenyan politicians that have been experienced in the country since it gained its independence from British colonialists in 1963, have plundered its resources – material and human – to the brink of war. It is no longer a valid argument that Africa, just because of a history of governments looting and plundering the vast resources that belong to the world’s poorest of the poor, in particular Kenya produces bad leaders. The second topic of discussion in this study questions the role of ethnic mobilisation during the elections. It is well documented by authors such as Cowen and Kanyinga (in Cowen and Laakso (eds.) 2002: 128-171) that ethnicity in Kenya, under the machinations of irresponsible political leaders, has in the past played a critical part in rallying one political party against another. The 2007 General Election was no different. The contested presidential election results were announced on 30 December, 2007, declaring another term of office for the incumbent president, Mwai Kibaki. Since that announcement, thousands of people were reported dead while hundreds of thousands were considered displaced. The chaos was followed by a long mediation process kicked off with the AU chairman, John Kufuor, president of Ghana, hosting a number of talks between the two parties. However, this did not bear much fruit as the two conflicting parties could not agree on the main issue of the creation of a position of Prime Minister for Raila Odinga to 7 fill. This was then followed by a more successful mediation process hosted by the Elders1 including former United Nations (UN) secretary general, Kofi Annan, Graça Maçhel and Benjamin Mkapa, as indicated by The Daily Nation newspapers throughout the month of January 2008. It is with this background that the study will now turn to the discussion about the context of the research, its objectives, rationale, motivation and the research design

- Description: Small and Medium enterprises (SMEs) play an important role as employers and in the economic growth of South Africa and in Africa as a whole. SMEs comprise over 90 percent of African business operations and contribute to over percent of African employment and GDP. SMEs sector has shown positive signs in South Africa, Mauritius and North Africa. SMEs constitute 95 percent of formal manufacturing activity in Nigeria. Senegal and Kenya have provided an environment which is conducive for SMEs (African Development Bank 2005). In August 2006, flood damage to small businesses and residential premises in the Nelson Mandela Metropolitan Area was estimated at R120million (SABC News 2006). The holding of an insurance cover by SMEs is crucial and beneficial to the economy and to the survival and success of the Small and Medium Enterprise sector. If a business has an insurance policy and a relationship with its insurer it becomes easier for the company to over come such a catastrophe. However, literature has shown that insurance companies are not willing to insure SMEs and it is the aim of this research to establish whether a relationship between the two constructs exists. An article entitled New Deal In The Offering for SMMEs, the author stated that the insurance industry prefer to deal only with established businesses (Mthimkhulu 2008). The aim of this research is to establish the importance of business relationship between Insurance companies and SMEs. The research will show how beneficial such a relationship is to both industries. The data for the research was collected through a survey type structured questionnaire that was developed and validated. The questionnaire was administered to the owners or managers of SMEs in the Nelson Mandela Metropolitan Area. The primary objective of this research was to establish whether SMEs in the Nelson Mandela Metropolitan Area have insurance policies for their businesses, and the results have shown that most of the SMEs in the Nelson Mandela Metropolitan Area do not have insurance policies for their businesses.

- Description: Globalisation and financial liberalisation has increased the linkages across countries in recent times. The existence of money market links has important implications for both domestic monetary policy and for investment decisions. This study examines the linkages between South Africa’s money market and selected major international money markets. The objectives of the study are firstly to examine the links between the repo rate of South Africa and the central bank rates of the EU, Japan, UK and US. Secondly, is to compare the influence of domestic and foreign monetary policy decisions on South Africa’s money market. The third objective is to examine the long run relationship between the South African money market and the money markets of its major trading partners. Three estimation techniques are used to examine the different links. Principal components analysis, four tests of cointegration, and stationarity tests of the spreads/risk premium between South Africa’s interest rates and the interest rates of the other countries. All three techniques show that there is no long-run link between South Africa’s central bank rates and the central bank rates of the other countries. This shows that the repo rate does not depend on movements in other central bank rates. Domestic money market interest rates respond strongly to changes in the repo rate whilst showing no dependence on central bank rates of the other countries. This confirms the autonomy of the South African Reserve Bank in carrying out policy objectives. When the risk premium is accounted for under the third technique, evidence of integration is found. This indicates that the risk premium plays a crucial part in the level of integration between South Africa and the countries included in the study.

- Description: Since 1929, the world economy has not encountered any financial crisis as severe as the case of the Great Depression, until 2007 when the fall of stock markets and the collapse of large financial institutions in the United States resulted in a worldwide recession. According to an IMF report, and as a result of the direct impact of the crisis, advanced economies such as those of the United States and Europe are suffering from a systemic banking crisis with economic output expected to contract by over 1 ¾ % in 2009. (Bourdin 2009:2) Although the crisis erupted in the United States, the effects quickly spread to countries worldwide. However, its effects are said to be more devastating for the poorest regions in the world including Sub-Saharan Africa. During the last few years, prior to the crisis, many Sub-Saharan African countries had enjoyed a growth rate of over 5%. This was partly as a result of sound economic policies and increased external support in the form of debt relief and higher inflows from economically powerful countries in the West. However, with the current financial crisis, wealthy nations have been forced to concentrate on sustaining their own economy. As a result, amongst changes like tighter immigration policies, skyrocketing oil prices and food prices, foreign aid is being withdrawn. (ibid 2009:3) According to foreign media reports, donor governments and the G8 are no longer as committed to aid as before the crisis. This research paper examines the evolution of aid to Africa in view of various contexts through a broad historical economic and political economy overview, and finally corroborates these observations with a discourse analysis of a sample of BBC online articles. The research project thus investigates in this last section, the BBC’s representation of poverty and aid in Sub-Saharan Africa before and during the current global economic crisis.

- Description: The South African Department of Health, like the health departments of many other countries, has reviewed its policies to focus on the delivery of comprehensive Primary Health Care (PHC). The South African health care sector is undergoing major restructuring in an attempt to address the inadequacies resulting from the fragmentation and duplication of health services in apartheid South Africa. Following this restructuring, the decentralisation to health services has been adopted as the model for both the governance and management of health issues (Department of Health, 2002:7). Before 1994, local government health departments were rendering certain primary health care services in terms of the Health Act 63 of 1977. Post 1994, the Constitution of the Republic of South Africa 1996 (Act 108 of 1996) classified primary health care as a provincial function. Based on this classification, primary health care services in South Africa are now being provided by two authorities, namely local government and provincial government, in the same community. Thus, in the Nelson Mandela Bay Municipality District, primary health care services are rendered by two authorities, namely the Nelson Mandela Bay Municipality and the Nelson Mandela Health District of the Eastern Cape Department of Health. These authorities are targeting the same community, with the same PHC package, with different sets of conditions of service, salary structures, infrastructure, accountability and authority. Such differences are believed to have impeded functional integration, depleted human resource capacity in rendering an effective and efficient PHC system and resulted in inefficient budget spending by both authorities. The problems of location, duplication and fragmentation of primary health care provision in the Nelson Mandela Bay Municipality District are not conducive to optimal service rendering. This will be resolved only once a unified, single integrated health service has been established. This study was undertaken to explore and describe the views of health practitioners with respect to the location of primary health care within the Nelson Mandela Bay Municipality District. The research design of this study was a quantitative, explorative, descriptive survey. Healthcare practitioners, like management, doctors and nurses, were asked to respond to a structured questionnaire. The findings of the study indicate that while health practitioners may hold diverse views on where primary health care should be located, they agree that a unified, single PHC authority would be desirable. Although primary health care is a combination of task-orientated basic health services and the process of community development, it is important that the authority of choice should ensure the highest possible quality through an integrated process, taking into account local needs. The recommendations made by the researcher on the conclusion of this study cover the principles on which a successful strategy for implementing primary health care should be based, including the need to create sustainable communities. It is hoped that the recommendations offered, will contribute to the more effective and efficient implementation of comprehensive primary health care services in Nelson Mandela Bay and also elsewhere in South African local government.

- Description: This research study aims to investigate the exchange students' experiences with living in a foreign environment. Twenty students took part in this study and were made up of two categories namely study abroad students and student interns. The twenty students who took part in this study were mostly from industrialized countries namely Germany, the United States of America, Belgium, the Netherlands and Sweden. Data were collected by means of individual semi-structured interviews as well as observational methods namely participant and simple observations. The results indicate that if sojourners are to gain a better understanding the South African culture, it is important that they interact with the host nationals. Given that most of the students highlighted the issue of crime as their main concern, their knowledge on how to survive in a crime-ridden country like South Africa would be essential.

- Description: This research sought to investigate the phenomenon of witchcraft-related crime in the Eastern Cape Province of South Africa, and its implications for law enforcement policy and practice. The primary motivation for a study such as this emerged from the need to address the lack of academic knowledge about witchcraft-related crime, especially in the Eastern Cape. The study is anthropological in focus, and is thus based on anthropological techniques of data gathering. Specifically, a literature study and fieldwork (semi-structured interviews and case studies) formed the basis of the research methodology employed. The geographical focus of the study was the northeastern part of the former Transkei, an area commonly referred to as Pondoland. Interview data were obtained from two categories of informants, namely community informants and informants of the South African Police Service (SAPS). Various towns and their surrounding villages were visited during fieldwork in order to gather data through interviews. Witchcraft continues to play an integral role in the cultural interpretation of misfortune, illness and untimely or mysterious death, particularly among local Xhosa-speaking communities that are predominantly rural. Beliefs associated with witchcraft were widespread in the study area and this was linked to high frequencies of witchcraft accusations and witchcraft-related violence. Police investigations of witchcraft-related cases were, for the most part, evaluated negatively by the majority of local community informants, while the SAPS informants indicated mixed responses as to the success of their investigations of these cases. The high frequency of unreported cases suggested that witchcraft-related crime is a problem in the Eastern Cape and that the local police were struggling to deal with these cases. The traditional leadership in various communities also struggled with the problem of an ambiguity in their role regarding witchcraft cases. Traditional leaders not only had jurisdictional limitations, but also indirectly seemed to encourage witchcraft-related violence by punishing those who accused others of witchcraft. In general, the relationship between communities, traditional leaders and the police were strained by witchcraft-related cases.

- Description: There has been an increase in the use of information technology in the hospital environment over the past decade and the use of computers by Nursing Managers is rapidly increasing. The latter poses a challenge to Nurse Managers, as their computer literacy status is unknown. This is evident from the fact that prior to 1996 there was only four computers at one of the private hospitals used in this study. Computer skills were never a requirement when applying for the position of Nurse Manager; and there is still currently no formal computer training provided for Nurse Managers or Acting Nurse Managers. Resources are however available in the hospitals to assist the managers with various computer problems but it is not known if these resources equip managers with the appropriate tools to become efficient in their role. The lack of formal training and lack of assessment of resources to determine whether the computer needs of Nurse Managers are met results in a lot of time being wasted and many frustrations experienced among Nurse Managers. The researcher was therefore motivated by the latter problem to explore and describe the computer literacy status of Nurse Managers in order to make recommendations to management regarding the research findings. The researcher selected a quantitative, explorative, contextual and descriptive survey design. The research population was made up of all Nurse Managers and Acting Nurse Managers at the time of the study. A 100 percent sample was utilised and comprised thirty-four respondents who made up the entire group of Nurse Managers and Acting Nurse Managers at the time of the study. A structured, self-administered questionnaire was used in Phase One of the research and in Phase Two a data observation sheet was used to test the respondents and to collect the necessary data. This data was manually processed and analysed by the iii researcher. All ethical considerations were honoured throughout the research process. The main findings of the research study reflected that the respondents had a below average ability to use various software packages such as Microsoft Word, EXCEL and Power Point. Findings further revealed that the respondent’s literacy levels were average with regard to the use of peripheral components of the computer such as the use of the mouse and keyboard. The respondents rated their competency level as average with regard to using a computer. Due to the limitations and small sample size used in the study the researcher recommends that further research using a larger sample by expanding the research into the other private hospitals in the group through out South Africa should take place in order to produce more constructive results than this study.

- Description: One of the greatest challenges facing the world today is integrating industrial activities such as mining with environmental integrity and social concerns. Monitoring is fundamental to environmental management, both to assess the adherence to standards and to allow environmental managers to learn from practical experiences. However, a problem arises when the regulatory authorities cannot keep up with their mandate of enforcement and compliance monitoring. This research examined how the Department of Minerals and Energy (DME) implements the concept of sustainable development in the mining sector of the Eastern Cape (EC) and, more specifically, the extent to which the Mine Environmental Management (MEM) section is able to effectively monitor compliance of mining operations with environmental legislation. This was the first systematic compilation of statistical data for the DME, and presents the first study in the EC regional office in terms of environmental sustainability. Results indicate that there has been a sustained increase in mining activity over the past three years, possibly as a result of the boom in the construction industry and the accelerated road maintenance and improvement programmes in the Eastern Cape. Mining applications received by the DME have increased by 47% from 2006 to 2007 (January-May) and by a further 100% from 2007 to 2008. In addition to the increasing number of mining concerns being established, 98 mining concerns will need to apply for the conversion of their old order rights to new order rights by the 1st May 2009. Mining in the province is predominantly small scale with mining permits (mined areas less than 1.5Ha) making up 52.3% of all applications, with larger mining concerns contributing 29.3% and prospecting contributing the remaining 18.4%. In terms of compliance inspections, the EC regional office is required to conduct 120 environmental compliance inspections annually in terms of contributing to sustainable development. The MEM section exceeded this target since 2003. However, when the number of operational mines is considered, 120 inspections per year equates to one mine being visited, on average once every four years (based on 2008 data). Based on projected figures (number of compliance audits and number of operational mines) for 2009, the DME’s target of 150 inspections for 2009/10 combined with the limited staff D. Watkins – MBA Dissertation 2008 capacity will, at best, mean that mines would be inspected once in seven years. However, the target of 150 inspections will not actually even cover the expected number of EMP evaluation inspections. This has serious implications in terms of regulating the compliance of the mining concerns with their EMPR’s. The low level of compliance monitoring can be directly related to staff capacity and logistics problems at the regional office as well as provincial targets being based on staff capacity rather than the number of operational mines. Thus, considering potential environmental damage associated with mining operations and the capacity constraints of the MEM to conduct frequent compliance audits, it is likely that mining operations will have negative implications for sustainable development in the region. Currently there are many challenges facing the DME in terms of contributing positively to sustainability in the mining sector and there is a need to base future actions on the idea of continuous improvement and ultimately progress.

- Description: This thesis is an assessment of the experience of small town local economic development in four towns namely Graaff-Reinet, Somerset East, Aberdeen and Pearston situated in the Eastern Cape Midlands, South Africa. It aims firstly to provide a critical overview of these selected small town economies before evaluating their local responses to the changing economic climate. The study is contextualized within the framework of locality development and emphasizes the heterogeneity of small towns with regards to physical, socio-economic, demographic and historical elements. From this, the original economic reasons for existence of these small towns are ascertained and then the major changes that occurred are identified. Amongst other aspects, the changes in the agricultural sector, the demographic changes particularly with regard to the significant increase in the urban population and the fluctuations in the quantity and types of businesses have all played a part in transforming the small towns' economies. As a result of these changes and many external driving forces such as changes in the regional and national economy, there are many severe challenges facing these small towns especially regarding the high unemployment rate, the associated poverty, HIV/AIDS and the low volume or absence of private investment into these localities. The responses of these small towns to the daunting challenges that they face have been considered in terms of Local Economic Development (LED) strategies that have been implemented. The LED initiatives in each town are examined in the context of their general characteristics, objectives, achievements and challenges. Emphasis is placed on Somerset East as it is the only town in the study area that has a development agency actively promoting various forms of LED. What has ultimately been established is: in all four towns, LED is not making a significant or meaningful difference and that natural market and economic forces play an important role in shaping and dictating the local economy. Somerset East is the only town where the economy could potentially be restructured with the proposed mega market-led approach to tourism and planning in the form of the Boschberg Development node. Four sectors perceived to be required for locality development are considered in this study, namely the export sector, the human resources, the local service sector and the government agencies. It is ascertained that although these sectors need to be part of a symbiotic relationship to promote and enhance economic development, they are not present in all the towns and as a result development, at both a household and a macro town level, is further hindered. Ultimately, these small towns in the Eastern Cape Midlands defy the notion that they are dying. 'Growth' and 'decline' have been two central features throughout this thesis and one of the biggest contradictions and challenges that these small towns face is the population growth with a declining or stagnant economy that cannot accommodate the increased number of people.

- Description: The profession of public relations has suffered negative associations and connotations as far as its role and practice are concerned. Alongside these, there are theories put forward within the field suggesting ways that could be used to assist public relations practitioners to become more successful in serving their organisations, marketing their organisation’s corporate image as well as reversing public relations’ negative legacy which has long existed as suggested by Steyn and Puth. This treatise argues that the real situation of the practice of public relations, its roles and the successes of PR practitioners in marketing the corporate image of their organisation might differ from what theories proposed. Thus this study seeks and intends to correlate what has been theorized with current practice in the profession. In addition, this study reflects and corroborates public relations practitioners’ roles in marketing the corporate image of organisations within the proposed new strategic role and through the existing traditional roles as compared to theory. Finally, this study also helps establish required changes to the traditional roles of the practitioners with the aim of reflecting the current situations in the existing selected organisations. In order to achieve the objectives of this study, the views and perceptions of public relations practitioners and managers of selected organisations were examined through a survey by questionnaire. This data was then analysed to determine their roles in marketing the corporate image of organisations in terms of the new strategic role and through the existing traditional roles as compared to theory. The sample included public relations practitioners and chief executive officers of Goodyear Tyre and Rubber Holdings (Pty) Ltd , Nelson Mandela Bay Municipality and Transnet National Ports Authority. The findings seem to support the hypotheses of the study in concluding that: The strategic roles identified in theory such as the solution around the myth and allegory of success in the practice and profession of public relations might not be realised in current practice, and Public relations practitioners’ effectiveness in marketing the corporate image of their organisations is affected by the way their roles are perceived within organisations. It is the hope of the researcher that, the findings of this investigation will set foundations for further research on the assessment and estimation of the practice of the public relations practitioners in marketing the corporate image of organisations.
