An ICT strategy to support a patient-centred approach to diabetes care

Petratos, Anastasia January 2017 (has links)
Factors such as poverty, ethnicity, socio-economic status, poor infrastructure and governance, etc., are some of the reasons that effective and proven prevention and treatment interventions for most of the major causes of mortality and morbidity in the developing world continue to fail. Chronic diseases require complex interventions that these countries simply cannot maintain. Diabetes mellitus (DM) is a chronic disease that is on the rise worldwide. This disease is a lifestyle disease, which means, that it is brought on by poor health habits. Statistics show that 285 million (6.4%) people aged between 20 and 79 years will be affected by Diabetes in 2010 and a staggering 439 million (7.7%) by 2030. This is a projected growth of 69% in developing countries and 20% in developed countries. The findings from studies conducted from 1993 to 2003 in Sub-Saharan Africa, particularly in South Africa, around the health care services for diabetes highlights many challenges. Sadly, the challenges 10 years after that study, are very similar. The conditions of people with Diabetes can be improved through regular monitoring of patients, improvement and monitoring of health care provided, education on healthy lifestyle, as well as education on the importance of adherence to treatment plans for the successful management of the condition. The diabetes endemic in South Africa is exacerbated by the manual functions that are performed in all aspects of monitoring and management of the disease. With the advancements that have been made in ICT and the many apps that already exist for healthcare, it is sensible to state that ICT can assist in the monitoring and management of diabetes. Another factor that is considered is that of patient-centred care. The huge number of people who need acute care and treatment in hospitals and clinics have forced a previously caring environment, to turn into a cold, almost production line affair. The sick wait in long queues and are ushered in and out of the consulting rooms as fast as possible without even as much as a “hallo”. This has left a void in the healthcare delivery to South Africans which should never have been removed in the first place, namely patient-centred care. This means that the patient is at the centre of the treatment and fully involved in the decisions about his/her health. Every patient deserves to be recognised as a human-being and treated with dignity and respect. Treatment plans for long term chronic care patients such as diabetics, should be thoroughly discussed with the patient and they should believe and comit themselves to the treatment plan. These plans are life-long and require dedication and as it is vital that patients are part of decision making and understand fully what they are expected to do. Bearing this in mind, this study has investigated the needs and care plans for people with diabetes. Specialist in the field of diabetes were interviewed and recognised care plans for diabetes such as those from WHO, IDF and SEMSDA were studied. This study also established, that by practising a patient-centred approach the adherence to a treatment plan is likely to be higher. The strategy developed involves the person with diabetes, the healthcare worker and the support structure in the care plan of the diabetic. The use of ICT as part of the solution must consider the patient-centred requirements for using IT so that the people using the strategy are comfortable and not intimidated by the technology. The need to incorporate e-health into governments’ healthcare plans has been growing over the last decade. The GSMA conducted research into mobile health opportunities in South Africa and found that SA now has a penetration of 98% and that this is the ideal medium to address the inaccessibility and inequality of healthcare in SA. The causes identified as playing a major role in the rise in diabetes were identified and it was determined that through the implementation of an ICT strategy for diabetes care, many of these can be addressed. These include the use of technology for, improved monitoring and management, increased diabetes awareness and education, and promotion of healthy lifestyle. The study focuses on the self-management aspect of diabetes and produces a strategy that incorporates various ICT solutions that would assist in the daily aspects of diabetes care, as well as follow a patient-centred approach to diabetes care. This strategy developed in this study does not need any intervention from government as it is driven by the people who have diabetes and their healthcare workers, with the aid of the technology that they currently have on hand.

Thermo-fluid effects associated with modelling subscale automotive heat exchangers

Gerova, Klementina January 2015 (has links)
Automotive components are tested extensively in wind tunnels by automotive manufacturers and race teams. This is usually achieved using an accurate scale model representation of the component within the wind tunnel. Automotive heat exchangers, however, are comprised of numerous intricate geometries and are therefore impractical to produce at model scale. Instead they are simply modelled as pressure drops, achieved using a thin mesh or honeycomb of known porosity. Most commercial computational fluid dynamics solvers ignore the geometry of the heat exchanger and instead model it as a discontinuity with a known pressure drop and heat transfer. The pressure drop across an automotive heat exchanger, however, was found to vary with both the coolant temperature and the angle of inclination of the heat exchanger. This thesis initially presents a relationship between the pressure drop coefficient and the inclination angle for varying media porosities. Mathematical relationships for inclination angles of 0°, 15°, 30° and 45°. were derived relating this pressure drop coefficient to the porosity of the media. Weighted least squares is proposed over ordinary least squares when obtaining the Forchheimer equation coefficients from experimental measurements. Investigation extends into the thermo-fluid effects on a full scale automotive heat exchanger when inclined at 0 °, 15°, 30° and 45°. It was found, depending on the angle, that there was a difference in the pressure drop of up to 10% between the unheated and heated (100 C) heat exchanger. Based on the proposed mathematical relationship, this correlated to a 4% decrease in porosity in order to accurately model the automotive heat exchanger at subscale. The thesis concludes with experimental and numerical investigation into the heat transfer on a hydrodynamically and thermally developing ow within a radiator channel. Laser doppler anemometry measurements recorded a 1.5% increase in the centreline velocity compared to 0.8% obtained from numerical simulation.

An evaluation of IMF structural adjustment programmes : lessons for South Africa

Berolsky, Nuno Goncalo January 2000 (has links)
The mixed results of International Monetary Fund structural adjustment programmes in less developed countries are a major motivation for this research. Explanations must be advanced as to what may inhibit the success of such programmes. South Africa has often found itself in a precarious position- with a deteriorating balance of payments, a position similar to other countries that have accepted IMF loans. Furthermore, South Africa undertook an IMF loan in 1993. Financial support from the IMF incorporates structural adjustment programmes. These may include measures such as tighter monetary policy, reduction in the budget deficit, exchange rate devaluation and ceilings on domestic credit with increased interest rates (Ferguson, 1988). These policies illustrate the principle of ‘conditionality,’ whereby access to further loans is conditional on certain criteria being met, such as reduced budget deficits and inflation rates. The principle of conditionality has met with a great deal of criticism. Bacha (1987) and Dell (1982) argue that these aggregate demand-reducing conditions more often than not stagnate domestic economies, worsening the balance of payment and result in programme breakdowns. Essentially, they refer to the IMF conditions as ‘unrealistic.’ The IMF denies this, arguing that shortfalls are mainly due to a lack of political commitment to carry out its conditions (Winters, 1994). This issue of conditionality will be examined in detail, using three specific case studies. The aim of this study is to examine the characteristics of Brazil, Mexico and Zambia to see whether or not the IMF programmes were successful. Guidelines will be established for South African policy from these case studies. South Africa is trying to adjust to the competitiveness of the international economy. At the same time, the need for reconstruction and development exerts increasing pressures on the balance of payments. Guidelines are established for a successful economic adjustment for South Africa. The research concludes that South Africa is certainly in line for a successful transformation. The rigidities are not as extensive as has been the case in Brazil and Zambia. Institutionally, South Africa is sound. However there are still challenges in this area, such as export diversification and economic stability to attract foreign investment.

A comparative analysis of derivative regulation following the global financial crisis : an emerging markets perspective

Mpala, Nqobile Natasha January 2015 (has links)
The international financial environment has become riskier due to the recent developments in product offerings and failure of regulation to keep abreast with these changes. The Global Financial Crisis exposed inadequacies of regulation, thus consensus on the need for comprehensive and uniform regulation was made by G-20 member states. Imposing exchange trading, clearing, reporting and capital requirements on the derivatives market are some of the ways of dealing with the problems caused by lax regulatory oversight. In this study, through the comparative analysis of derivatives regulation in South Africa, Brazil, India and Turkey, it was established that emerging countries are taking active steps to implement the G-20 agreement. Uniformity in the core rules was noted, with differences in the supportive legislation. Country specific rules which support the macroeconomic factors that are faced by these countries and the infrastructure available for regulatory execution are used amongst countries. The study concluded that current regulation in emerging countries is accommodative and regulatory differences are in line with economic factors in each country.

Valuation of banks in emerging markets: an exploratory study

Sabilika, Keith January 2014 (has links)
Practitioners and academics in emerging markets are yet to agree on how best they can value companies in emerging markets. In contrast, academics and practitioners in developed markets seem to agree on mainstream valuation practices (Bruner, Eades, Harris and Haggins, 1998; Graham and Harvey, 2001). This study was therefore aimed at achieving such consensus with particular attention being paid to the emerging market banks. Emerging market banks are by no means small and are growing fast. Furthermore, these banks are currently involved in lots of cutting age economic activities such as mergers and acquisitions (M&A), joint ventures and strategic alliances which require sound valuation practices that are based on empirical evidence. The primary purpose of this research was to establish consensus of opinion among experts with regard to the valuation of banks in emerging markets. To achieve the purpose of this study the Delphi technique, which is a structured survey method that relies on a panel of experts to answer questionnaires in two or more Delphi rounds, was used to gather data and develop consensus among experts (Kalaian and Kasim, 2012). The main findings in this study pertain to aspects concerning the type of analysis considered by experts when analysing the performance of banks, how experts compare the discounted cash flow (DCF) approach to multiples valuation approach, the challenges encountered by experts when valuing banks in emerging markets, and how experts compute the cost of capital for banks in emerging markets. The main findings of this study can be summarised as follows: ∙ When analyzing the performance of banks, it is essential to conduct a bank-specific, industry and macroeconomic analysis; ∙ When estimating the future performance of banks, the time series analysis and an explicit forecast period of between 4-10 years may be used; ∙ When estimating the terminal value for banks in emerging markets, the perpetuity with growth is used; ∙ When computing the value for banks, the DCF valuation approach (equity DCF and DDM valuation models) are used as primary valuation methods and the relative valuation approach (P/E and P/BV ratio) are used as secondary valuation methods; ∙ The DCF valuation approach is considered as more accurate and popular when valuing banks in emerging markets; and ∙ When estimating the cost of equity, the capital asset pricing model (CAPM) is used.

The legal and regulatory aspects of international remittances within the SADC region

Mbalekwa, Simbarashe January 2011 (has links)
Migrant labourers who cross borders often have to send money back to their various countries of origin. These monetary transfers are known as remittances. To send these funds migrants often opt to rely on informal mechanisms as opposed to the remittance services of formal financial institutions such as banks. Informal remittance mechanisms raise a number of concerns such as those related to consumer protection. In contrast to formal channels informal channels are not based on any legally binding agreements. They are highly based on trust and do not offer any legally binding guarantee that the funds will be delivered or that the remitter will be reimbursed in the event of non-delivery. Aside from consumer protection concerns, informal remittances also raise security related concerns. These channels are not subject to the supervision of any regulatory authority and usually offer a high level of anonymity. They can act as an attractive mechanism for terrorists and criminal organisations to launder and mobilise their illicit funds. Taking into mind the concerns mentioned above, as well as others, it would be preferable for more remittances to be channeled through formal financial mechanisms. In conducting research on remittance transactions financial, as well as other institutions and organisations, have outlined legal and regulatory provisions in sending and recipient countries as being a factor that often hinders migrants from accessing formal financial services. This dissertation examines how the South African legal and regulatory framework affects the formalisation of remittances by migrant labourers, with a focus on the context of low-income migrants. The study identifies the Exchange control, immigration, anti-money laundering and anti-terrorism legislative provisions as being the most significant provisions that affect the formalisation of migrant remittances. So as to make an analysis and gather recommendations were possible, a comparison of the South African legal and regulatory provisions is made to those of Zambia and Zimbabwe. The dissertation comes to the conclusion that South African legal and regulatory provisions hinder the formalisation of migrant remittances to a certain extent. They do so by collectively and individually restricting migrants who do not fulfill legislative requisites from accessing formal remittance channels. It is submitted that such migrants are inclined to rely on informal remittance mechanisms when the need to send money arises. Furthermore, South African law restricts competition within the remittance market by making it difficult for service providers to enter the market. The lack of an adequate competitive level fosters the prevalence of high remittance costs which can pose a significant barrier to low income migrants that wish to channel funds via formal means. Taking into mind the significance of formalising remittances as well as the objectives that the laws that hinder them seek to attain, which are equally significant, it is necessary for the regulatory authorities to investigate ways on how to possibly cater for both. It is submitted that if more remittances were to be channeled through official means the objectives sought to be attained by some of these legislative provisions would be attained more efficiently.

Stuchelová, Jana January 2011 (has links)
My dissertation is focused on description of characteristics which are connected with competences. The main aim of my work has been to set up the manager competences. After the analysis among the students of Faculty of Management we found which competences were obtained during our studies and which ones we had already had when we came to faculty. In my theoretical part I described the manager as a personality including all his competences, their development and the methods of developing. Practical part deals with analysis among the students of Faculty of Management, evaluation and presentation of the results in the form of the charts and graphs.

Developing Capacity: The IMF's Impact on State Capacity

Harper, Christine 12 1900 (has links)
The purpose of this thesis is to examine the impact of International Monetary Fund (IMF) loans since the adoption of the governance mandate on overall government capability. The study will explore whether the presence of IMF loans in developing countries enhances state capacity. Administrative capacity is of particular importance because it is a requisite for the integration of state and society in the national political arena and encourages joint involvement of government and citizenry in overall representation of societal interests. The model designed to test the two primary hypotheses is comprised of a simultaneous system of equations. Despite criticisms of IMF conditionality arrangements, it appears that these programs are largely effective at increasing administrative capacity, an important factor in achieving economic growth and national ownership of IMF development programs.

An econometric study of an oil-exporting country: the case of Iran

Heiat, Abbas 01 January 1986 (has links)
The main objective of this study is to contribute toward an analytical and empirical work on the oil-based developing economy of Iran. It focuses on the aggregate behavior of the Iranian economy through a simple linear econometric model. After a survey of the literature on the theoretical framework of macroeconomic models for the developing countries in general, and for the oil exporting developing countries in particular, a linear econometric model for the Iranian economy is formulated and its logical and economical aspects are explained. The proposed model consists of basic consumption, production, foreign trade, and employment relationships. Estimation of the behavioral equations are carried out by Ordinary Least Square and Two Stage Least Square estimators. The model is estimated over the period of 1959-76. Data published by the Plan and Budget Organization of Iran in the 1978 edition of the "Economic Trends of Iran" are used for the estimation of the parameters of the model. Historical simulation of the model has been performed to test the validity and the fitness of the model as a whole. The results obtained from the estimation of the consumption functions seem to indicate that the aggregate Iranian consumption behavior can be best explained by Friedman's Permanent Income Hypothesis. An attempt has been made to estimate the aggregate production function of the urban sector according to various Cobb-Douglas production functions and linear production function with constant returns to scale. All of these specifications gave implausible results. In general, the results of this study demonstrate that the links between different sectors of the Iranian economy are very weak and the import substitution strategy of the government during the period of study failed to establish a genuine domestic industrial base and to reduce its dependence on foreign resources.
