This thesis explores the spatial patterns and determinants of asthma prevalence and health services use (ICD-10 codes J45, J46) for the total population (all ages and both sexes combined) of the province of Ontario, Canada, between 2003 and 2013. Asthma is characterized by high health services use and reduced quality of life for asthma sufferers, representing a considerable burden on individuals, society and the health care system. While recent evidence suggests increasing asthma prevalence in Ontario, little research has been done to understand the identified spatial variability of this disease. Using population-based, ecological-level data and refined spatial analysis techniques, this research aims to explore the spatial patterns of asthma prevalence and health services use in Ontario, and examine the contribution of potential risk factors including air pollution, pollen, deprivation, physician supply and rurality. Results indicated considerable spatial variability in asthma outcomes across Ontario. Similar patterns were found between asthma prevalence and physician visits; clusters of high rates were generally found in southern urban/suburban areas, and clusters of low rates were mainly identified in most northern and southern rural areas. Conversely, clusters of high rates of ED visits and hospitalizations were found in most northern and southern rural areas, whereas clusters of low rates were found in south urban/suburban areas near Toronto. Findings from the spatial regression analysis indicated that while rurality was negatively associated with asthma prevalence and physician visits, it was positively associated with ED visits. Moreover, positive associations were also found between material deprivation and asthma prevalence and ED visits, and between NO2 and asthma physician visits. This research contributes to a better understanding of area characteristics that influence asthma disparities, which can help develop better, locally relevant public health strategies aimed at reducing the burden of asthma in Ontario. Further, it demonstrates the importance of using a population-based framework and spatial analysis approaches, which take into account the spatial nature of asthma morbidity and their determinants.

Over the last couple of decades changes to pediatric inflammatory bowel disease (IBD) care may have altered health services use among these children. I used a retrospective matched cohort design and population-based health administrative data to first quantify trends in IBD health services and surgical outcomes in Ontario IBD children diagnosed between 1994-2012. I then used these results to validate the distributed network analysis method – a method being increasingly used in Canadian multi-province studies where privacy regulations prevent sharing of individual-level data across provincial borders - using Ontario’s Local Health Integration Networks. I found (1) decreasing hospitalizations and surgical outcomes but increasing outpatient visit rates, suggesting changing patterns of health care use in Ontario children with IBD, and, (2) distributed network analyses is a satisfactory privacy-preserving alternative to individual-level analysis under the conditions tested in my study, providing a tested analysis method for researchers using multi-jurisdictional data.

M.Tech. (Production Management) / The development of technikons into autonomous tertiary technical educational institutions, offering education up to doctorate level, conducting research, offering vocational and continuing education, brought with them libraries which cannot provide in the requirements set to them. This study investigates the place for a library in the Technikon Witwatersrand and some of the environmental influences that have a bearing on the library. It continues from there to determine the library infrastructure of the Witwatersrand in order to establish the presence and accessibility of information sources. A framework is then developed according to which the needs of the users of the library determined. user categories are then identified and their needs for information sources determined. The study continues from there to develop this framework on a computer so that it can be used in planning for the provision of information sources to technologists in the future. The study is concluded with recommendations regarding the provision of information sources.

People´s access to safe health care is not as common as one might think. Today with new and different health insurances and improved health policies people should in theory have safe health care. Although numerous of health insurances exist, targeting large parts of populations, there are still many issues with them. The Behavioural Model of Health Services Use and Separate Spheres are the two theories that are used in this study. Where Separate Spheres describes men´s and women´s separate worlds, their responsibilities in them and how it effects them and the Behavioural Model of Health Services Use, which describes factors that either impede or enable people’s access to health care utilization. This study´s purpose is to see what different perceptions men and women have about the insurance and how these perceptions can affect families’ choice to enroll to the insurance. The study uses a qualitative approach and is based on semi-structured interviews. Results in this study showed that men and women have very different perceptions about the insurance. Men want the insurance because they want to save money and decrease health expenses. While women wants the insurance for their children to always have access to health care. The roles between men and women in households are significant and their different responsibilities affect their priorities and perceptions.

In 2000, midwifery was regulated in the Canadian province of Manitoba. Since the inception of the midwifery program, little formal research has analyzed the utilization of regulated midwifery services. Currently, many women are denied access to midwifery care due to the shortage of midwives in Manitoba. The specific objectives of this mixed-methods case study were to describe the utilization of midwifery health care services in Manitoba from 2001/02 to 2009/10 and to explore factors influencing the implementation and utilization of regulated midwifery services in Manitoba. The study was guided by the Behavioral Model of Health Services Use (Andersen, 1995). Data collection and analysis were an iterative process between documents, interviews, and administrative data. The quantitative analysis used the population-based administrative data housed at the Manitoba Centre for Health Policy to study the utilization of midwifery care. There was modest growth in the overall rate of midwifery-attended births, as well as in the number of midwives over the 10-year time period. Twenty-four key informants were purposefully selected to participate in semi-structured interviews for the qualitative component. Interviews were audio-taped, transcribed verbatim and analyzed using content analysis. Three main topic areas were identified: barriers, facilitators, and future strategies/recommendations. Themes arising under barriers included conflict and power; lack of an educational program; perceptions of the profession, and a precarious profession. Issues of gender underpinned some of these barriers. Constituent influence was a prominent facilitator of the profession. Future strategies for sustaining the midwifery profession focused on ensuring avenues for registration and education, improving management strategies and accountability frameworks, enhancing the work environment, and evaluating the model of practice and employment. Results of the document analysis supported the themes arising from the interviews. In spite of scientific evidence that supports the midwifery model of care, there remains an inherent struggle to justify the profession and ensure its widespread implementation in Manitoba. The findings have implications for maternal child health professionals working on collaborative efforts to facilitate access to midwifery services for women. This study adds to the growing body of literature related to midwifery in Canada.

This study seeks to undertake an analysis of the topic of 'science and the media' as it has been constituted in academic discourse since the end of the Second World War. It finds that concern has polarized in two distinct camps: The larger, participant in the traditional project of North American media studies, blames the press for what it perceives as a widespread and deleterious "scientific illiteracy" on the part of the laity. The more recent, indebted to critical developments in social theory, philosophy of science, and the study of mass communication, works to expose the assumptions on which press coverage of science has been based and the interests which have benefited. / The thesis argues that the adequacy of the dominant concern to its object of analysis is at best suspect, but that nevertheless its agitations have been chiefly responsible for the form which popular science has predominantly assumed.

M.Bibl. / Television producers form a unique user group that mainly requires information regarding audio-visual material in order to produce or to enhance a television programme Information services can contribute to the successful completion of a programme by making information available. The aim of this study is to determine whether information services can enhance information for producers by adding value. The question is also asked which value-added level of information is required. A literature study was done to -examine the term "value-added" in order to be able to apply it to the information needs of television producers; -study the work environment of television producers in order to determine their information needs. An empirical investigation was executed by means of a layered random sampling test. Structured interviews were conducted by means of a questionnaire with a random portion of the television producer corps of the SABC. Personal details were gathered, as well as the use of information sources and services within the SABC and to which value- added level of information they require for a production. Value-added levels were based on Taylor's value-added continuum which consists of information that is enhanced to level two, Information Knowledge, followed by level three, Productive Knowledge, which leads to level four, Action. A television production is completed in four phases, that is the planning and research phase, filming phase, editing phase and final mixing phase .. The results showed that during the planning and research phases television producers require access to all possible information sources and services within the SABC. The information specialist can add value to the first level of value adding. In certain cases the television producers require information during the editing phase, during which the information specialist can add value up to the third level. The results of the research were distilled into a matrix, structured to indicate the levels of added-value to the television producer. Recommendations were made in order to provide a better information service.

The aim of this study was to investigate the Web-based information behaviour of high school learners in Oshana Region in Namibia. The study also considerd the challenges faced by learners when searching the Web for information. For many years in the history of library and information services, print-based information had been the main source of information. However, since the emergence of the Internet and its rapid development, the Internet has provided an almost unlimited pool of Web-based resources, thus becoming a powerful source of information. The Web is now established as the main medium for the wide dissemination of information across the Internet. Within the academic context learners throughout the world are able to retrieve seemingly endless volumes of information across all disciplines and from all over the globe. It is therefore important to study the behavior of young people in relation to Web-based information because it is today one of their most important sources of knowledge. The findings of this study could assist in curriculum design, especially with regard to Basic Information Science (a subject offered in schools in Namibia), which incorporates information literacy and information-seeking skills development. In addition the study provides some insight into the information and computer literacy levels of learners and proposes ways of responding to these, thus assisting in further developing these important literacies. The study was guided by Wilson’s (1999) model of information behaviour. The model attempts to describe an information-seeking activity and suggests relationships among stages in information-seeking behaviour. The study has adopted a quantitative approach as its methodology. Data from a total of 160 respondents was collected using a questionnaire that consisted of both open ended and closed questions. The study’s research questions investigate how, where and when do Grade 12 learners access the Internet, for what purposes do Grade 12 learners use the Web when looking for information, how do Grade 12 learners search for information on the Web, what are the Web information searching skills of Grade 12 learners, what sources of information on the Web do Grade 12 learners use, how do Grade 12 learners evaluate and use information found on the Web, and what are the challenges faced by Grade 12 learners when searching the Web for information. The survey concentrated on Matric learners (grade 12) from Mweshipandeka HS and Gabriel Taapopi SSS in the Oshana region of Namibia. The results were analysed using SPSS as a tool for data analysis. An interpretation of the findings of this study shows that learners Web-searching skills are inadequate. Overall, there was a high level of familiarity with various Web-information sources such as search engines, although users limited themselves mainly to a few sources such as the search engines Google and Yahoo and the online encyclopedia, Wikipedia. Learners were not aware of Google's limitations and of the existence of academic, often library-funded, information sources such as databases and electronic journals. The present study found strong indications that grade 12 learners lack information-evaluation skills as well as acknowledgement skills and that they are not aware of what constitutes plagiarism. This appears to be a result of poor training in schools. However, the status of learner’s access to the Internet is good. Both schools involved in this study provide learners with physical access to the Internet. / Thesis (M.I.S.)-University of KwaZulu-Natal, Pietermaritzburg, 2013.
