New submissions to the thesis/dissertation collections are added automatically as they are received from the Graduate School. Currently, the Graduate School deposits all theses and dissertations from a given semester after the official graduation date. This means that there may be up to a 4 month delay in the appearance of a give thesis/dissertation in DRUM

    WRITTEN IN STONE: A LANDSCAPE APPROACH TO EXAMINING OHIO PETROGLYPH SITES
    (2021) Goodrich, Christopher; Lafrenz-Samuels, Kathryn; Anthropology; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    A petroglyph study was completed using a novel combination of landscape theory and GIS spatial analysis in Ohio. Building on the knowledge base of James L. Swauger’s 1984 publication of Petroglyphs of Ohio, petroglyph site data was checked against the Ohio State Historic Preservation Office Archives. These data were then compared with regional and local geology, hydrology, and known cultural sites using a GIS database. Significant insights were discovered linking petroglyph site locations to Ohio’s unglaciated plateau, “open areas consisting of sandstone,” and to waterways. These insights have contributed to the development of a new baseline of petroglyph knowledge in Ohio, paving the way for future petroglyph research in the state.Keywords: petroglyph, GIS, spatial analysis, landscape archaeology, Ohio archaeology

    THE INFLUENCE OF URBAN FORM AT DIFFERENT GEOGRAPHICAL SCALES ON TRAVEL BEHAVIOR; EVIDENCE FROM U.S. CITIES
    (2016) Nasri, Arefeh; Zhang, Lei; Civil Engineering; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    Suburban lifestyle is popular among American families, although it has been criticized for encouraging automobile use through longer commutes, causing heavy traffic congestion, and destroying open spaces (Handy, 2005). It is a serious concern that people living in low-density suburban areas suffer from high automobile dependency and lower rates of daily physical activity, both of which result in social, environmental and health-related costs. In response to such concerns, researchers have investigated the inter-relationships between urban land-use pattern and travel behavior within the last few decades and suggested that land-use planning can play a significant role in changing travel behavior in the long-term. However, debates regarding the magnitude and efficiency of the effects of land-use on travel patterns have been contentious over the years. Changes in built-environment patterns is potentially considered a long-term panacea for automobile dependency and traffic congestion, despite some researchers arguing that the effects of land-use on travel behavior are minor, if any. It is still not clear why the estimated impact is different in urban areas and how effective a proposed land-use change/policy is in changing certain travel behavior. This knowledge gap has made it difficult for decision-makers to evaluate land-use plans and policies. In addition, little is known about the influence of the large-scale built environment. In the present dissertation, advanced spatial-statistical tools have been employed to better understand and analyze these impacts at different scales, along with analyzing transit-oriented development policy at both small and large scales. The objective of this research is to: (1) develop scalable and consistent measures of the overall physical form of metropolitan areas; (2) re-examine the effects of built-environment factors at different hierarchical scales on travel behavior, and, in particular, on vehicle miles traveled (VMT) and car ownership; and (3) investigate the effects of transit-oriented development on travel behavior. The findings show that changes in built-environment at both local and regional levels could be very influential in changing travel behavior. Specifically, the promotion of compact, mixed-use built environment with well-connected street networks reduces VMT and car ownership, resulting in less traffic congestion, air pollution, and energy consumption.
