Access Beyond Geographic Accessibility: Understanding Opportunities To Human Needs In A Physical-Virtual World, Jimmy Feng

Doctoral Dissertations

Access to basic human needs, such as food and healthcare, is conceptually understood to be comprised of multiple spatial and aspatial dimensions. However, research in this area has traditionally been explored with spatial accessibility measures that almost exclusively focus on just two dimensions. Namely, the availability of resources, services, and facilities, and the accessibility or ease to which locations of these opportunities can be reached with existing land-use and transport systems under temporal constraints and considering individual characteristics of people. These calculated measures are insufficient in holistically capturing available opportunities as they ignore other components, such as the emergence of …

Geography Of Health Care Access: Measurement, Analyses And Integration, Huairen Ye

Doctoral Dissertations

This dissertation addresses the geography of healthcare access and disparity issues in the United States using geospatial methods. Disparities in access to quality healthcare services are of great concern in the field of both public health and geography. Access is a key element within the healthcare delivery system, influenced by both spatial factors and non-spatial factors. Focusing on the spatial dimensions of access, an innovative contribution of this dissertation is the integration of spatial modeling, geo-statistics and location problems in a Geographic Information System (GIS) environment to investigate healthcare access.
