- Description: A voluminous literature attempts to explain the various channels of the monetary policy transmission mechanism through which central banks ultimately achieve price stability. However, most research focuses on interest rate pass-through and the demand for money phase, while there is limited research on the demand for credit. This study endeavours to contribute to the understanding of this neglected phase of monetary policy transmission by exploring the response of the real demand for bank credit by the private sector to changes in the real prime rate from 1990:1 to 2004:4 in South Africa. Firstly, the behaviour of the real prime rate in relation to the repo rate is explored using graphical analysis. The study observes that an increase in the repo rate causes an increase in the real prime rate, such that there is always a margin of three or four percentage points between the two rates. Secondly, using secondary data, the Johansen methodology is used to determine the relationship between the demand for bank credit and its determinants (GDP, inflation, real prime rate and real yield on government bonds). Two co-integrating relationships are found. The Gaussian errors from one co-integrating vector are used to model the Vector Error Correction Model, which provides the short-run dynamics and the long-run results, through the use of Eviews 5 software. The results of the study show that while all other variables are negatively related to the demand for bank credit in the long-run, GDP has a positive influence. In the short-run, yield on government bonds and inflation coefficients depict a positive association, while the coefficients of real prime rate and GDP are negative. The error correction coefficient is -0.32, which implies that a 32% adjustment to equilibrium happens in the demand for bank credit in a quarter and that the complete adjustment takes about three quarters to complete. Thirdly, the generalised impulse responses results indicate that the impact on the real prime rate affects the demand for bank credit from the first quarter. The study concludes that the real prime rate has a negative impact on the demand for credit both in the short-run and long-run.

- Description: The principal objective of this thesis was to gain an understanding of the movement patterns of spotted grunter Pomadasys commersonnii, an estuarine-dependent fishery species, in the turbid, freshwater dominated Great Fish Estuary. Both manual and automated telemetry methods were used to monitor the movements of spotted grunter during two separate studies conducted in summer and spring 2003 and 2004. Acoustic transmitters were surgically implanted into twenty spotted grunter with lengths between 263 and 387 mm TL in the first study and twenty spotted grunter ranging between 362 and 698 mm TL in the second study. The specific objectives were to gain an understanding of (i) the time spent in the estuarine environment (ii) the space use and home range size, and (iii) the abiotic factors governing the movement patterns of spotted grunter in the estuary. The nursery function of estuarine environments was highlighted in this study as adolescent spotted grunter spent a significantly larger proportion of their time in the estuary than adult fish (p < 0.0001; R² = 0.62). The increased frequency of sea trips, with the onset of sexual maturity, provided testimony of the end of the estuarinedependent phase of their life-cycle. Although considered to be predominantly marine, the adult spotted grunter in the Great Fish Estuary utilised the estuary for considerable periods. Adults are thought to frequent estuaries to forage, seek shelter and to possibly rid themselves of parasites. During this study, the number of sea trips made by tagged fish ranged from 0 to 53, and the duration ranged from 6 hours to 28 days. The tidal phase and time of day had a significant effect (p < 0.05) on the sea trips undertaken by fish. Most tagged spotted grunter left the estuary during the night (84%) on the outgoing tide, and most returned in the evening (77%) during the incoming tide. Sea temperature (p < 0.0001; R² = 0.34), barometric pressure (p = 0.004; R² = 0.19) and wind (p = 0.01) had a significant effect on the number of spotted grunter recorded in the estuary. Spotted grunter were more prone to return to the estuary after high barometric pressure, when low sea temperatures (upwelling events) prevailed. There was a significant positive relationship between home range size and fish length (p = 0.004; R² = 0.20). Small spotted grunter (< 450 mm TL) appeared to be highly resident, with a small home range (mean size = 129 167 m²), that was generally confined to a single core area. Larger individuals (> 450 mm TL) occupied larger home ranges (mean size = 218 435 m²) with numerous core areas. The home ranges of small and large spotted grunter overlapped considerably yielding evidence of two high use areas, situated 1.2 km and 7 km from the mouth of the Great Fish Estuary. Tagged spotted grunter were located in a wide range of salinity, turbidity and temperature, but were found to avoid temperatures below 16 ºC. The daily change in environmental variables (salinity, temperature and turbidity) had a significant effect on the change in fish position in the estuary (p < 0.0001; R² = 0.38). The distribution of tagged spotted grunter, particularly the larger individuals, in the Great Fish Estuary was influenced by the tidal phase (p < 0.05); they moved upriver on the incoming tide and downriver on the outgoing tide. This study provides an understanding of the movement patterns of spotted grunter in the estuary and between the estuarine and marine environments. Consequently, it provides information that will assist in the design of a management plan to promote sustainability of this important fishery species. The techniques used and developed in this study also have direct application for further studies on other important estuarinedependent fishery species.

- Description: Performance management systems help align individual goals and objectives with those of the organisation. The system engages employees and thereby directs them toward achieving the strategic goals of the organisation. The purpose of this research study was to conduct an investigation at a manufacturing jeweller in the Western Cape to establish whether a performance management system would facilitate the achievement of the organisation’s strategic goals and objectives. Preliminary investigations showed that the organisation was using a performance appraisal process which was not effective in facilitating the organisation’s strategic objectives. Based on the initial investigation, this study was undertaken. To achieve the goals of this study, 33 employees of the organisation were presented with a questionnaire based on important key elements of performance management. Responses were received from 31 employees, of which one was from senior management, two from management, three from supervisory staff, and 25 from general staff members. Their responses to the questionnaire were analysed and evaluated and, based on the findings, recommendations were made. The results of the study showed that problems exist in the organisation which impede achievement of its strategic goals. A performance management system would assist the organisation in many of these areas to overcome the identified problems. The results of the study will enable the management of the organisation to design and implement a performance management system to facilitate the achievement of the organisation’s strategic goals.

- Description: This research examines procedural modeling in the eld of computer graphics. Procedural modeling automates the generation of objects by representing models as procedures that provide a description of the process required to create the model. The problem we solve with this research is the creation of a procedural modeling environment that consists of a procedural modeling language and a set of non-interactive modeling tools. A goal of this research is to provide comparisons between 3D manual modeling and procedural modeling, which focus on the modeling strategies, tools and model representations used by each modeling paradigm. A procedural modeling language is presented that has the same facilities and features of existing procedural modeling languages. In addition, features such as caching and a pseudorandom number generator is included, demonstrating the advantages of a procedural modeling paradigm. The non-interactive tools created within the procedural modeling framework are selection, extrusion, subdivision, curve shaping and stitching. In order to demonstrate the usefulness of the procedural modeling framework, human and furniture models are created using this procedural modeling environment. Various techniques are presented to generate these objects, and may be used to create a variety of other models. A detailed discussion of each technique is provided. Six experiments are conducted to test the support of the procedural modeling benets provided by this non- interactive modeling environment. The experiments test, namely parameterisation, re-usability, base-shape independence, model complexity, the generation of reproducible random numbers and caching. We prove that a number of distinct models can be generated from a single procedure through the use parameterisation. Modeling procedures and sub-procedures are re-usable and can be applied to different models. Procedures can be base-shape independent. The level of complexity of a model can be increased by repeatedly applying geometry to the model. The pseudo-random number generator is capable of generating reproducible random numbers. The caching facility reduces the time required to generate a model that uses repetitive geometry.

- Description: In terms of the common law contract of employment an employee who is a party to a fixed term contract, unlike an indefinite period contract, cannot be dismissed. The contract terminates upon an agreed or ascertainable date determined by the parties and the conclusion of the contract. Section 186(1)(b) of the Labour Relations Act 1995, however, defines the failure to renew a fixed term contract on the same or similar terms where the employee reasonably expected the contract to be renewed, as a dismissal. In this treatise the scope and content of this provision is considered with reference to relevant case law. The factors and considerations that establish a reasonable expectation are highlighted and considered. The question as to whether or not this provision also provides for the situation where an employee expects indefinite employment is also considered and critically discussed. The author concludes that the provision should not be interpreted in such a manner that an expectation of permanent employment is created.

- Description: The nutrient dynamics in two contrasting estuaries and in the adjacent nearshore environment along the south-east coast of South Africa was investigated seasonally. Due to an inter-basin transfer of water from the Gariep Dam to the Great Fish River, the Great Fish estuary is a fresh water dominated, terrestrially driven system with an annual fresh water inflow of 250 – 650 x 10⁶ m³ per year. In contrast, the Kariega estuary is a fresh water deprived, marine dominated system with a fresh water inflow estimated at 2.5 – 35 x 10⁶ m³per year. The reduced fresh water inflow into the estuary is attributed to regular impoundments along the Kariega River. Water samples were collected from surface and subsurface layers along the length of the estuaries as well as from a series of transects occupied in the nearshore environment. Samples were analysed for nitrate, nitrite, ammonium, phosphate and silicate. Temperature and salinity were recorded at each station. A Land-Ocean Interactions in the Coastal Zone (LOICZ) budget was constructed for each estuary to describe the role of ecosystem-level metabolism as either a sink or a source of phosphorus, nitrogen and carbon. Seasonal variation in physico-chemical properties and nutrient concentrations in the Kariega estuary was minimal due to constant low inflow, while in the Great Fish estuary, concentrations varied in response to changes in flow rate. Nutrient concentrations were consistently higher in the Great Fish estuary than in the Kariega estuary, largely reflecting differences in fresh water inflow. During periods of high flow (32.92 m³.s⁻¹in the Great Fish River) dissolved inorganic nitrogen (DIN) concentrations in the Great Fish estuary were an order of magnitude higher than those recorded in the Kariega estuary. Results of the LOICZ budgeting procedures revealed that in spite of the contrasting hydrodynamic features, the estuaries behave in largely the same manner – both predominantly sources of nutrients with heterotrophic processes dominating over autotrophic actions and both were net denitrifyers during all surveys. This was, however, due to different sets of processes operating in the two estuaries, namely low nutrient concentrations resulting in microbial activity in the Kariega estuary, and riverine influx of nutrients and phytoplankton combined with a short residence time of the water in the Great Fish estuary. In the marine nearshore environment, higher nutrient concentrations were recorded adjacent to the Great Fish estuary than offshore of the Kariega estuary. This was due to a surface plume of less saline water leaving the Great Fish estuary, which acted as an ‘outweller’ of nutrients. Offshore of the Kariega estuary, on the other hand, the nutrient concentrations were characteristic of marine waters due to a lack of fresh water outflow from the estuary. Nutrient concentrations in the marine environment adjacent to the Kariega estuary were, at times, higher than those recorded within the estuary. This observation supports previous statements which suggest that the Kariega estuary is not an ‘outweller’ of dissolved nutrients and particulate material, but rather an extension of the marine environment.

- Description: Photovoltaic (PV) modules based on thin film systems of CuInSe2 (CIS) and its alloys on low cost substrates are promising candidates to meet the long term efficiency, reliability and manufacturing cost goals. The attention to the CIS solar cell technology is because of the high absorption coefficient of the solar cell absorber layer. Solar cells and PV modules are conventionally assessed by measuring the currentvoltage characteristic of the device. This thesis presents an assessment procedure developed capable of assessing the device parameters with reference to I-V measurements. This thesis then characterizes the performance of the CIS based solar cells and modules in conjunction with other PV modules of different technologies such as crystalline Silicon modules by analyzing the light and dark I-V measurements of the devices. The light and dark I-V characteristics of PV devices were investigated and device parameters were extracted from the I-V data. The extraction and interpretation of these device parameters has a variety of important applications. It has been proven that the device parameters can be used for quality control during production and to provide insights into the operation of the PV devices, thereby improving the efficiency of the devices. The assessment comprises light I-V measurements at standard test conditions (STC), irradiance dependence measurements, parasitic series and shunt resistances measurements and the dark I-V measurements of the PV devices. The PV modules assessed comprise different technologies, namely, thin film based modules (CIS and a-Si) and multicrystalline Si and Edged-defined Film-fed Growth Si (EFG-Si). The dark I-V measurements results showed that the EFG-Si module has acceptable shunt (900 W) and series (0.4 W) resistances, thereby leading to the higher power output depicted from the light I-V measurements. The low quality cells of a-Si module were so low that the fill factor was the smallest (43%). In addition, the dark I-V measurements results revealed that CIS modules are less dependent to temperature at high voltages.

- Description: Photovoltaic (PV) modules based on thin film systems of CuInSe2 (CIS) and its alloys on low cost substrates are promising candidates to meet the long term efficiency, reliability and manufacturing cost goals. The attention to the CIS solar cell technology is because of the high absorption coefficient of the solar cell absorber layer. Solar cells and PV modules are conventionally assessed by measuring the currentvoltage characteristic of the device. This thesis presents an assessment procedure developed capable of assessing the device parameters with reference to I-V measurements. This thesis then characterizes the performance of the CIS based solar cells and modules in conjunction with other PV modules of different technologies such as crystalline Silicon modules by analyzing the light and dark I-V measurements of the devices. The light and dark I-V characteristics of PV devices were investigated and device parameters were extracted from the I-V data. The extraction and interpretation of these device parameters has a variety of important applications. It has been proven that the device parameters can be used for quality control during production and to provide insights into the operation of the PV devices, thereby improving the efficiency of the devices. The assessment comprises light I-V measurements at standard test conditions (STC), irradiance dependence measurements, parasitic series and shunt resistances measurements and the dark I-V measurements of the PV devices.

- Description: The need for alternative strategies for the prevention and treatment of diabetes is growing rapidly as type II diabetes is reaching epidemic status in our society. This need was the basis for the creation of this study, as it was necessary to start looking towards medicinal plants as potential antidiabetic treatment and no comprehensive in vitro model existed. In creating a model for determining the effects of alternative traditional medicines as antidiabetic potentiates, it was necessary that two metabolic pathways, namely glucose uptake and insulin secretion, which play a significant role in glucose homeostasis, be at the centre of our investigations. The objective of this project was to optimize the methodology required to screen and ultimately determine the effectiveness of the plant extracts Kankerbos and MRC2003, as antidiabetic potentiates, through observing their effects on glucose utilisation and insulin secretion. If these medicinal plants are going to make a positive contribution to the health of type II diabetic South Africans, then the determination of their efficacy is essential. The cell lines used in this study included 3T3-L1 preadipocytes, Chang liver, C2C12 muscle and INS-1 rat pancreatic cells. Each cell line represents a different in vivo organ that is known to have an influence on glucose homeostasis in our bodies, each with its own unique metabolic pathways and mechanisms of activity, thereby making each one a vital component in the study. The positive controls for the two models were insulin and metformin (glucose utilisation) and glibenclamide (insulin secretion). Insulin was shown to provide a significant increase in the amount of glucose taken up in C2C12 muscle and Chang liver cells for acute conditions. Chronic treatments with metformin provided a significant increase in glucose utilised by Chang liver cells. Glibenclamide was an effective positive control for stimulating insulin secretion by INS-1 cells under acute conditions as there was a significant increase in the amount of insulin secreted. MRC2003 did not show any significant antidiabetic activity. Sutherlandia frutescens (Kankerbos) showed biological activities comparable to some of the more recognized antidiabetic compounds throughout the study. With regards to the glucose utilisation model, Kankerbos was seen to have both acute and chronic effects in different cell lines. In the C2C12 muscle cell line, Kankerbos significantly increased glucose uptake when they were exposed to acute conditions. Kankerbos also had a significant effect on the Chang liver cells as it was observed that under both acute and chronic conditions, this plant extract induced the uptake of glucose into these cells. With respect to the insulin secretion model involving INS-1 cells, no significant effect was seen during acute exposure with Kankerbos treatment. However during chronic exposure, an increase in insulin secretion was initiated by this plant extract. Overall, the results of this study suggest that Kankerbos has a twofold mechanism of action for its glucose-lowering effects. Given that Kankerbos is widely available in South Africa, this study was valuable as it provided an indication that Kankerbos has antidiabetic activities and could possibly be used as an alternative antidiabetic medication.

- Description: Future Search is a new concept in Namibia. This study looks at the application of a Future Search Conference (FSC) with the Nursing Board of Namibia with a view to investigating participants' experiences and perceptions of the FSC as an organizational change strategy. I conducted a case study in the interpretive paradigm, since I was interested in understanding the subjective experience and individual perceptions of five respondents with regard to the FSC. To obtain in-depth information on how participants felt about the FSC, I employed two data gathering tools: un-structured individual interviews and observation. The findings confirmed that the Future Search is a new concept in the Ministry of Health in particular and in Namibia as a whole. Participants are of the opinion that leaders and managers are key figures in the success or failure of the Future Search. They showed a tremendous interest in the process and are willing to embrace and master the tool so they could try it in their various areas of work. Emphasis was put on the need to get the FSC introduced to leaders and higher management cadres on a wider scale, because they are decision makers and can decide whether or not the Future Search could be institutionalized. This study concludes with an appeal from respondents to be exposed to the Future Search again in a better time frame than the short time we had.

- Description: Evidence suggests that the prevalence of certain non-communicable diseases, such as hypertension, is increasing rapidly, and that patients with these diseases are making significant demands on the health services of the nations in sub-Saharan Africa. However, these countries also face other health-related challenges such as communicable diseases and underdevelopmentrelated diseases. Developing countries like South Africa have limited resources, in terms of man power and financial capital, to address the challenges that they are facing. Non-communicable diseases cannot be ignored and since health care providers cannot meet the challenges, it is worthwhile to empower patients to be involved in the management of their conditions. Patient education is a tool that can be used to enable patients to manage their chronic conditions and thereby reduce the morbidity and mortality rates of these conditions. The aim of this study was to investigate the effect of a patient education intervention on participants’ levels of knowledge about hypertension and its therapy, beliefs about medicines and adherence to anti-hypertensive therapy. The intervention consisted of talks and discussions with all the participants as one group and as individuals. There was also written information given to the participants. Their levels of knowledge about hypertension and its therapy were measured using one-on-one interviews and self-administered questionnaires. Beliefs about medicines were measured using the Beliefs about Medicines Questionnaire (BMQ) whilst adherence levels were measured using pill counts, elf-reports and prescription refill records. The participants’ blood pressure readings and body mass indices were also recorded throughout the study. The parameters before and after the educational intervention were compared using statistical analyses. The participants’ levels of knowledge about hypertension and its therapy significantly increased whilst their beliefs about medicines were positively modified after the educational intervention. There were also increases, though not statistically significant, in the participants’ levels of adherence to anti-hypertensive therapy. Unexpectedly, the blood pressure readings and body mass indices increased significantly. The participants gave positive feedback regarding the educational intervention and indicated a desire for similar programmes to be run continuously. They also suggested that such programmes be implemented for other common chronic conditions such as asthma and diabetes. This study proved that patient education programmes can be implemented to modify patients’ levels of knowledge about their conditions and the therapy, beliefs about medicines and adherence to therapy. However, such programmes need to be conducted over a long period of time since changes involving behaviour take a long time.

- Description: This study analyses Uganda’s 2004 Broadcast Policy in light of the WSIS principles in order to establish whether the policy enables radio to build an inclusive and people-centred Information Society, and if so, in what ways it does this. The study specifically focuses on radio, which it views as the dominant medium in Uganda, and therefore the medium with the greatest potential to build a sustainable Information Society in the country. The study is informed by media policy theories as well as Information Society theories. It is argued that although most definitions of the Information Society consider the newer ICTs, especially the Internet, as the key drivers in the Information Society, most developing countries like Uganda are far from reaching the desired level of computer and Internet access as proposed by some Information Society theorists. Instead, most people in Uganda rely heavily on older ICTs, especially radio, for information about key issues in their daily lives. Inevitably, radio ends up being a key player in building the Information Society in these countries. The study, therefore, finds most of the common Information Society theories lacking and adopts the WSIS definition, which is more relevant to Uganda’s situation. This study also maintains that if radio is to be a key player in building an inclusive and people-centred Information Society in Uganda, the 2004 Broadcast Policy has to create that enabling environment, by, for example, promoting public service radio through local content programming, and diversifying radio ownership. The data for this study was obtained using the qualitative research approach, and specifically the research tools of document analysis and individual in-depth interviews. The findings indicate that the policy’s emphasis is on building a broadcast sector that addresses the public’s interests through local content programming and provision of diversified media services. However, the study also found that the policy is vague on some very crucial aspects, which would benefit the public, namely, local content quotas and the independence of the public service broadcaster.

- Description: The objective of this research was to establish a means to assist, and ultimately encourage, small and micro building contractors to develop and submit a Workplace Skills Plan (WSP) that both qualifies for levy grant recovery and provides strategic value to the organisation. Targeted contractors are those who do not have the know-how necessary to develop such a WSP. Thus the need for a basic approach or model that will, through its simplicity and ease of application, assist and encourage such contractors nonetheless to undertake the process. Achieving this objective required a detailed examination of relevant literature and legislation, to identify the basic or minimum requirements for developing a strategic WSP and for meeting grant recovery regulations respectively. Newly released grant recovery regulations were examined to identify the implications thereof, and to establish the minimum legislative requirements, for the WSPs of small and micro contractors. Existing relevant general training and training needs assessment models were examined to identify the requirements for developing a strategic WSP. To establish the minimum strategic requirements it was necessary to firstly identify all the requirements proposed by the different models for identifying and meeting the training needs of an organisation, and thereafter reach a decision regarding which could be considered as minimum requirements. The decision rule for selection as a minimum strategic requirement was inclusion in all the surveyed models. To enable a less subjective analysis than relying solely on the opinion of the researcher, a content analysis was selected as the research technique, as the steps of a typical content analysis include a number of measures to increase objectivity. The legislative and strategic requirements identified by the study were converted into a series of simple sequential action steps to formulate a practical model that would guide the targeted contractors through the process of developing a value-adding WSP.

- Description: Performance Management aims to develop the employee and ensure that the work which the employee does is in line with organisational goals. However, many managers and employees do not like performance management systems and very often, for this reason, such a system does not succeed in meeting the organisation’s goals. The aim of this study was to determine the perceptions towards the performance management system of pharmacists working in the public sector. A questionnaire was compiled and pharmacists working in all public sector hospitals, provincial and municipal clinics and medical depots were asked to complete the questionnaire. The response rate was 66 percent. Seventy three percent of respondents had never undergone a performance evaluation, 75 percent stated it did not motivate them, 62.5 percent felt it did not improve poor performance, 90.6 percent felt the Performance Appraisal System did not reward good performance sufficiently and 63.6 percent felt it did not help with career progression. Seventy eight percent believed that the Performance Appraisal System did not effectively measure the pharmacists’ performance, and 82 percent felt that the System needed to be developed further. At least four evaluations should have been completed per year, yet 85 percent of respondents had experienced three or fewer evaluations since the System had been introduced. The analysis of the responses indicated that there was great dissatisfaction with the current performance management system. A few of the reasons are that the system in place did not effectively measure the pharmacists performance, that additional work done was not recognised, and that the process was extremely time-consuming. It may be concluded that the government needs to address the current problems being experienced with this system, as at present, it is not meeting the objectives it was intended to meet.

The aim of the research was to examine the abundant expressions of aggression that were present within his therapy, and in so doing reflect their rich communicative content and their relevance and purpose in the development of his Self. Object relations theory formed the lens and theoretical context for this research with Winnicott’s contributions and Parens' model of aggression being considered in particular. A detailed data resource of the therapy process was compiled and transposed into narrative form. These narratives were reviewed with a reading guide as a means to facilitate a hermeneutic exploration of the data. The emergent themes were considered against the case data and the current theory, which allowed for their further analysis and development. From this the value of using Parens’ model was considered and deemed useful although limited in its contribution. The analysis and the themes which emerged conveyed how within this case the child’s aggression presented as: a significant feature of his ambivalence towards relationships; a powerful and pervasive protective fantasy of omnipotence; inherently linked to his sense of self and self expression; and as actively involved in his True Self’s hope-filled attempts for an alternative experience. This thesis provides a descriptive account of a challenging case, offering insights into the value and meaningful content of aggressive behaviours, with the intention being to reflect that which is often not easily appreciated or readily observable within such a therapy process, a trace of hope.

- Description: The last decade has seen an exodus of South African nurses migrating to "greener pastures". As a result of this migration, the South African Healthcare Service has been drained of one of its most essential resources – nurses. Subsequently, the crippling flight of nurses has thrown the nursing profession into a state of crisis. The Kingdom of Saudi Arabia is one of the more popular destinations for South African nurses, the main reason being the attractive financial rewards. One agency reports that they send an average of thirty nurses a month to various hospitals within the Kingdom of Saudi Arabia. Saudi Arabia is an Islamic country. Due to the uniqueness of the enforcement of the Islamic faith and the Saudi culture, many restrictions are imposed, particularly on women. The challenges and problems facing the South African nurses were, therefore, unique compared to elsewhere in the world. This research study had a primary and a secondary objective: The primary objective of this study was to explore and describe the lived experiences of South African nurses related to living and working in Saudi Arabia; The secondary objective of this study was to develop orientation guidelines to support South African nurses working and living in Saudi Arabia. The researcher utilized a qualitative, explorative, descriptive and contextual design based on a phenomenological approach to inquiry, in an attempt to answer the question: "What are the professional and personal experiences of the South African registered nurses working and living in Saudi Arabia?" Eleven registered nurses were selected to participate by means of purposive sampling. These nurses had been living in Saudi Arabia between three and six months. Consent was obtained from participants and the ethics committee of both the Nelson Mandela Metropolitan University and King Faisal Specialist Hospital and Research Centre. The central theme emanating from the study was recognized as being 'Cultural Diversity'. The sub-themes identified related to the registered nurses’: - Religious/spiritual adaptation - Environmental adaptation - Emotional/psychological adaptation - Professional adaptation Based on the identified themes, guidelines were formulated to assist South African registered nurses when migrating to Saudi Arabia. Utilization of these should assist the South African registered nurse in assimilating into both the cultural and working environment. However, in reality, the outcome showed that no one can be prepared fully for what awaits them in Saudi Arabia.

- Description: Diabetes Mellitus (DM) is on the increase globally, with further increases expected in developing countries, such as South Africa. World Health Organization (Medical Chronicle, 2006:14) estimations indicate that the number of DM sufferers will double over the next 30 years. This increasing number of diabetics is expected to have enormous economical implications. One of the consequences of the increase in DM sufferers is the increase in deaths due to diabetes related complications. In 2000, 3.2 million people died of DM and diabetes related complications compared with 3 million who died from HIV/AIDS related illnesses (William & Pickup, 2004:64). Health services are financially burdened by DM complications that result in heavy demands in both direct costs of hospitalization and medication as well as indirect costs such as manpower of staff involved in the care of the patient (Leuner, 2000:410). Diabetic ketoacidosis (DKA) is a prominent life-threatening complication of type 1 diabetes mellitus and, if not treated medically, it can lead to coma and death. DKA accounts for 14 per cent of all diabetic related hospital admissions and has a mortality rate of 5 to 10 per cent (Pickup & Williams, 2003:1). Rapid identification of DKA is necessary to improve patient care. George- Gray and Chernecky (2002:96) suggest patient outcomes are affected by the nurse’s ability to recognize the clinical features of DKA. It is important, therefore, for the nurses to understand the signs and symptoms and treatment of this diabetes related complication. National health policies and treatment guidelines should be aimed at addressing DKA treatment through setting guidelines for diabetic care (Peters, 2004:22). The main goal of this study was to determine registered nurses’ knowledge of DKA and to develop guidelines to assist registered nurses in providing adequate and effective health care to prevent DKA reoccurrence. The research study is based pm Bergam’s model on quality of care and accountability. Bergman claims that several preconditions must be filled in order to be accountable, including: • Accountability • Responsibility • Authority • Ability (Bergman (1982:8) emphasizes that ability reflects the registered nurses’ accountability, which is composed of values, knowledge and skills.) The study was divided into two phases. Phase one determined registered nurses’ knowledge related to the management of DKA. Phase two of the study included the developing guidelines to assist registered nurses in providing adequate and effective health care to patients with DKA. The design of the study is quantitative, explorative, descriptive and contextual; a survey was performed using a questionnaire based on a literature study. Ethical principals were maintained throughout the study. Permission to the study was sought from the Local Health Authorities and the heads of department where the research was undertaken. Findings of the research were analysed and discussed in the research. The knowledge of the majority of the respondents was found to be average. Out of the thirty- two respondents 52.8 percent possessed adequate knowledge the management of DKA and 63.4 percent possessed adequate knowledge on the management of DM. Two recommendations to assist registered nurses in the implementation of guidelines of the recommendations were also provided.

- Description: The complex environment of an intensive care unit is associated with a considerable amount of stress. Intensive care nurses are confronted daily with increasing work demands, emanating from the growing numbers of critically-ill patients; the introduction of highly sophisticated technologies in the intensive care environment; increasing competition between health care institutions; increased work loads; and limited career opportunities caused by, among other things, budget cuts by the government (Janssen, De Jonge & Bakker, 1999:1360). Research has shown that such stressors can result in mental, physical and behavioural stress reactions among nurses (Demerouti, Bakker, Nachreiner and Schaufeli, 2000:454). The objective of this study is to explore and describe registered nurses’ perceptions of factors causing stress in intensive care environments of state hospitals. The main purpose of the study is to develop guidelines for a stress management programme, to assist registered nurses to cope with the stressors in an intensive care environment. The research design is placed within a quantitative, explorative and descriptive contextual framework. Validity and reliability in testing and evaluating the research questionnaire are discussed, as well as the ethical and legal considerations relating to this research study. Findings of the research study will be utilized to assist the researcher in developing guidelines for a stress management programme to assist registered nurses in coping with stress in an intensive care environment

- Description: This research investigates the relationship between employee performance, leadership and emotional intelligence in a South African parastatal. The literature provided discusses the three variables of performance, leadership and emotional intelligence. Information was gathered, using three instruments, from a sample of 160 leaders and 800 raters. The Multifactor Leadership Questionnaire was used to determine leadership style within the parastatal, while the Emotional Competency Profiler was used to determine the emotional intelligence of the leaders within the parastatal. Employee performance was captured and recorded using the parastatal’s performance appraisal process. Leadership and emotional intelligence were identified as the independent variables and employee performance as the dependent variable. Data obtained from each of the research instruments was then statistically analysed. Through linear regression analysis it was concluded that there is a significant relationship between employee performance and an emotionally intelligent, transactional leader. However, no significant linear relationship was found between employee performance and an emotionally intelligent, transformational leader. Simple correlation analysis showed that there is a relatively weak significant linear relationship between emotional intelligence and transactional leadership. Moreover, it was found that there is a very strong significant linear relationship between emotional intelligence and transformational leadership. This research therefore adds a new dimension to employee performance, leadership and emotional intelligence, since no similar study has been conducted. As this research takes place in the South African context, it contributes to the bank of findings relating to the concepts.

- Description: The South African formal education system has undergone many changes since the formulation of the White Paper on Education and Training in 1995. These developments challenge organisations that want to run successful programmes or projects in schools to adapt their social marketing strategies. Against this background, the aim of the study was to investigate the relationships between social marketing strategies and participation of schools in environmental competitions. The goals of the research were to identify issues that have influenced schools participation in the Collect-a-Can Annual Schools Competition, identify and review social marketing strategies used by Collect-a-Can to influence participation of schools in the competition, and identify relationships between issues that influenced school participation in the competition and the Collect-a-Can’s social marketing strategies. A qualitative design that applied an interpretative case study, which focused on the Collect-a-Can’s Annual Schools Competition was used to explore these relationships. Data was generated through interviews, document analysis and a workshop. Nine respondents from nine schools and three Collect-a-Can management staff members participated in the interview process. Twenty participants from twenty schools participated in the workshop. The findings of the research revealed that there were relationships between the social marketing strategies used by Collect-a-Can and participation of schools in the competition. These relationships were found to be linked mainly to policy changes within formal education which Collect-a-Can could not respond to as a result of various reasons which included among others, the core focus of thecompany, lack of funds and a need to operate in a cost-effective way. The recommendations indicate possible areas for improvement and guidelines which could be used by Collect-a-Can for the competition without digressing from its core focus or incurring additional costs. These include a more responsive and adaptive management approach and a stronger educational orientation.
