Purpose In Place: Discerning And Forefronting Forgotten Landscapes Using The Methodological Lens Of Augmented Reality, Lindy Westenhoff

Doctoral Dissertations

Augmented reality (AR) is an under-studied tool that deserves more academic attention and gaze. By using the built landscape as its point of orientation, but providing a virtual interface with which to engage, the augmented landscape serves as a departure of the traditional digital-physical divide. This realm raises questions regarding purpose and intention, but also has its own limitations and issues with dynamic, complex spaces that change frequently. Each chapter of this dissertation stands alone as a “part” – they connect, however, through the use of this technology to answer questions unique to their spaces.

Part 1 explores the relationship …

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 …

Reflecting Human Knowledge Of Place And Route-Choice Behavior Using Big Data, Jiaoli Chen

Doctoral Dissertations

Exploring human knowledge of geographical space and related behavior not only helps in understanding human-environment interactions and dynamic geographic processes, but also advances Geographic Information Systems (GIS) toward a human-centric paradigm to make daily life more efficient. Today’s relatively easy acquisition of various big data provides an unprecedented opportunity for geographers to answer research questions that previously could not be adequately addressed. However, new challenges also arise regarding data quality and bias as well as change in methodology for dealing with big data that are different from traditional data types.

Geographic And Socioeconomic Risk Factors For Sporadic Cryptosdporidiosis And E. Coli Infection In East Tennessee, Ingrid Elizabeth Luffman

Doctoral Dissertations

This research examines risk factors for sporadic cryptosporidiosis and Escherichia coli (E. coli) O157 infection in East Tennessee, using case-control and retrospective ecological approaches. Multiple models and approaches are used to identify risk factors for the two diseases, and to examine the effect of scale on risk for disease in the individual and in the population. Risk factors examined are animal density, land use, geology, surface water impairment, poverty rate and availability of private water supply. The research objectives are, first, to identify risk factors for E. coli O157 and cryptosporidiosis in East Tennessee by relating disease data …

Human Interactions In Physical And Virtual Spaces: A Gis-Based Time-Geographic Exploratory Approach, Ling Yin

Doctoral Dissertations

Information and communication technologies (ICT) such as cell phone and the Internet have extended opportunities of human activities and interactions from physical spaces to virtual spaces. The relaxed spatio-temporal constraints on individual activities may affect human activity-travel patterns, social networks, and many other aspects of society. A challenge for research of human activities in the ICT age is to develop analytical environments that can help visualize and explore individual activities in virtual spaces and their mutual impacts with physical activities.

This dissertation focuses on extending the time-geographic framework and developing a spatio-temporal exploratory environment in a space-time geographic information system …
