The goal of this study was to explore the relationship between psychosocial and demographic characteristics associated with success among individuals with rheumatoid arthritis. Unlike previous research which has predominantly focused on the limiting effects of rheumatoid arthritis, the present study sought to identify factors that were related to success. One hundred and ninety-eight individuals who met the criteria for this study, returned completed questionnaires. Success for people with rheumatoid arthritis was measured on the scales of self-esteem, social activity, and physical activity. Participants were categorized as either "high" or "low" on the success scales in order to see what demographic and psychosocial variables were related levels of self-esteem, social activity, and physical activity. Data analysis included reliability of the success scales, and analysis of variance to determine the relationship among the three scales and selected demographic characteristics. Discriminant analysis was used to explore what demographic and psychosocial factors were related to high (as opposed to low) self-esteem, social activity, and physical activity among 24 participants. The success scales were found to be reliable. There was no significant relationship among the success scales and sex, occupational level, and ethnicity. Results of the discriminant function identified that generally, individuals with high (as opposed to low) self-esteem were very motivated and had a positive outlook on life. People with high (as opposed to low) social activity had fewer physical limitations and a better view of themselves. High (as opposed to low) physical activity was found among people who generally were highly motivated and believed they had some control over their rheumatoid arthritis.

This thesis defines a novel and intuitive method to visually represent attribute uncertainty, and spatial boundary uncertainty generated from choropleth maps. Like all data, it is not possible to know exactly how far from the truth spatial data used for choropleth mapping is. When spatial data is used in a decision-making context a visual representation of data correctness may become a valuable addition. As an example, the visualisation of uncertainty is illustrated using choropleth mapping techniques superimposed on New Zealand 2001 census data, but other spatial datasets could have been employed. Both attribute and spatial uncertainty are considered, with Monte Carlo statistical simulations being used to model attribute uncertainty. A visualisation technique to manage certain choropleth spatial boundary issues (i.e. the modifiable areal unit problem - MAUP) and uncertainty in attribute data is introduced, especially catering for attribute and choropleth spatial boundary uncertainty simultaneously. The new uncertainty visualisation method uses the quadtree spatial data model (SDM) in a novel manner. It is shown that by adapting the quadtree SDM to divide according to uncertainty levels possessed by attributes (associated with areal units), rather than divide on the basis of homogeneous regions (as the original quadtree design was intended), a measure of attribute and choropleth spatial boundary uncertainty can be exhibited. The variable cell size of the structure expresses uncertainty, with larger cell size indicating large uncertainty, and vice versa. The new quadtree SDM was termed the trustree. A software suite called TRUST v1.0 (The Representation of Uncertainty using Scale-unspecific Tessellations) was developed to create square trustree visualisations. The visual appeal and representational accuracy of the trustree was investigated. Representative accuracy and visual appeal increased when using hexagonal tessellations instead of the quadtree�s traditional square tessellation. In particular, the Hexagonal or Rhombus (HoR) quadtree designed by Bell et al. (1989) was used to programme TRUST v1.1. Using the HoR quadtree in rhombic mode (TRUST v1.1.1) produced Orbison�s optical illusion, so it was disregarded. However, the HoR trustree (the hexagonal tessellation produced by TRUST v1.1.2) was adopted for further research and user assessment. When assessed using an Internet survey, the HoR trustree adequately displayed choropleth spatial boundary uncertainty, but not attribute uncertainty. New trustree visualisations, the value-by-area (VBA) trustree and adjacent HoR trustree were developed to help increase the expression of attribute uncertainty. Upon reassessment, the new trustree visualisations were deemed usable to express attribute uncertainty and choropleth spatial boundary uncertainty at a modest 58% usable (HoR trustree), 80% usable (VBA trustree) and 85% usable (adjacent HoR trustree). A usability test (where participants were asked to spot different levels of uncertainty) validated these results, whereby the HoR trustree achieved a 65% accuracy level and the VBA trustree achieved an 80% accuracy level. The user assessments helped to highlight that the trustree could be used in two ways, to express detail within or clutter over areal units. The HoR trustree showed (1) a level of detail (or resolution) metaphor, where more detail represented more accuracy and/or the reverse, (2) a metaphor of clutter, where the data structure output was sufficiently dense as to cover spatial information, in effect hiding uncertain areas. Further Internet survey testing showed the trustree tessellation works better when representing a metaphor of detail. Attribute and spatial uncertainty can be effectively expressed depending on the tessellation level used. Overall, the new TRUST suite visualisations compare favourably with existing uncertainty visualisation techniques. Some uncertainty visualisation methods consistently performed better than the TRUST visualisations such as blinking areas, adjacent value and non-continuous cartograms. Other methods like colour saturation, image sharpness and a three-dimensional surface frequently performed with less usability. Therefore, the TRUST visualisations have found their place amongst other uncertainty visualisation methods. However, survey results showed that TRUST is a viable option for visualising two forms of uncertainty - attribute and spatial uncertainty. No other visualisation method has these capabilities. Further research could include a laboratory assessment of TRUST and also incorporating vagueness and temporal uncertainty concepts. Additionally, end-user testing could provide a valuable insight into uncertainty visualisation for everyday use. Adopting uncertainty methods to uncertainty, such as the technique presented here, into the mainstream decision making environment could be considered a fundamental objective for future investigation in spatial studies.

Since 1994, a turning point in the history of South Africa (SA), significant changes were made in the delivery of health services by the public sector, provincially and nationally. The process of change involved making important decisions about health services provision, often based on past experience but ideally requiring detailed information on health status and health services. For an example, Primary Health Care (PHC) was made freely accessible to all citizens of this country. Many studies on the impact of free PHC in the country have shown increased utilization of these services.40 In the context of HIV/AIDS and its complications and other emerging health conditions, reasons for this increased utilization may not be that simple. I17, II8. Parallel with increased utilisatIon has been uncontrollable escalation of costs in the Department of Health (DoH), often resulting in ad-hoc and ineffective measures of cost-containment.40. For these and many other reasons of critical importance to public health services management, the issue of health information generally, and epidemiological inforn1ation in particular, should be brought higher on the agenda of health management. Public health services management is about planning, organization, leading, monitoring and control of the same services.2 Any public health plan must have a scientific basis. In order to achieve rational planning of public health services in the province, adequate, up to date, accurate information must be available, as a planning tool. Health information is one of key resources and an essential element in health services management. It is a powerful tool by which to assess health needs, to measure health status of the population and most importantly, to decide how resources should be deployed.5 Trends in the health status of the population are suggested by the White Paper for transforn1ation of Health Services (White Paper), to be important indicators of the success of the Reconstruction and Development Programme (RDP), the country's programme of transformation. 37,39 It is within that context that the KwaZulu-Natal-Department of Health (KZN-DoH) resolved to establish an Epidemiology/Demographic Unit for the province, to assist management to achieve the department's objectives of providing equitable, effective, efficient and comprehensive health services. 37,89 Purpose: To develop a provincial Epidemiological-Demographic Inforn1ation System (EDIS) that will consistently inforn1 and support rational and realistic management decisions based on accurate, timely, current and comprehensive infom1ation, moving the DoH towards evidence based policy and planning. Objectives: To provide an ED IS framework to : .develop provincial health policy .assist management with health services planning and decision-making .ensure central co-ordination of health information in order to support delivery of services at all levels of the health system . . monitor implementation and evaluation of health programmes . ensure utilization of information at the point of collection, for local planning and interventlon. Methods: A rapid appraisal of the existing Health Information System (HIS) in the province was conducted from the sub-departments of the DoH and randomly selected institutions. A cross-sectional study involving retrospective review of records from selected hospitals, clinics and other sources, was conducted. The study period was the period between January 1998 to December 1998. Capacity at district and regional levels on managing health information and epidemiological information in particular, was reviewed and established through training progranmles. Results: The rapid appraisal of existing HIS in the province revealed a relatively electronically well resourced sub-department of Informatics within the KZN-DoH, with a potential to provide quality and timely data. However, a lot of data was collected from both clinics and hospitals but not analyzed nor utilized. Some critical data was captured and analyzed nationally. There was lack of clarity between the Informatics Department staff responsible for collecting and processing provincial data and top management with regards each other's needs. Demographics: The demographic composition and distribution profile of the KZN population showed features of a third world country for Blacks with the White population displaying contrasting first world characteristics. Socio-Economic Profile: The majority of the population was unemployed, poor, illiterate, economically inactive, and earning very low income. The water supply, housing and toilet facilities seemed adequate, but in the absence of data on urban/rural distinction, this finding needs to be interpreted with caution Epidemiology: All basic indicators of socio-economic status (infant, child, neonatal mortality rates) were high and this province had the second poorest of the same indicators in the country. Adult and child morbidity and mortality profiles of the province, both at clinics and district hospitals were mainly from preventable conditions. Indicators on women and maternal health were consistent with the socio-economic status of this province; and maternal mortality rate was high with causes of mortality that were mainly preventable. The issue of HIV / AIDS complications remains unquantifiable with the limited data available. HIV is a serious epidemic in KZN and this province continues to lead all the provinces in the country, a prevalence of 32 % in 1999.86 Health Services Provision: Inmmnization coverage was almost 50% below the national target and drop out rate was very high. Termlinations of Pregnancies (TOP) occurred mainly among adult, single women, and the procedure done within the first trimester and requested for social and economic reasons. Provincial clinics (mainly fixed) and hospitals provide family planning and Ante Natal Care (ANC) services to the majority of pregnant women in the province. Conclusion : KZN is a poor province with an epidemiological profile of a country in transition but predominantly preventable health conditions. The province has a potential for producing high quality health information required for management, planning and decision making. It is recommended that management redirects resources towards improving PHC services. Establishment of an Epidemiology Unit would facilitate the DoH's health services reforms, through provision of comprehensive, accurate, timely and relevant health information . / Thesis (M.Med.)-University of Natal, Durban, 2000.
