abstract: In "Between Mountain and Lake: an Urban Mormon Country," I identify a uniquely Mormon urban tradition that transcends simple village agrarianism. This tradition encompasses the distinctive ways in which Mormons have thought about cities, appropriating popular American urban forms to articulate their faith's central beliefs, tenants, and practices, from street layout to home decorating. But if an urban Mormon experience has as much validity as an agrarian one, how have the two traditions articulated themselves over time? What did the city mean for nineteenth-century Mormons? Did these meanings change in the twentieth-century, particularly following World War II when the nation as a whole underwent rapid suburbanization? How did Mormon understandings of the environment effect the placement of their villages and cities? What consequences did these choices have for their children, particularly when these places rapidly suburbanized? Traditionally, Zion has been linked to a particular place. This localized dimension to an otherwise spiritual and utopian ideal introduces environmental negotiation and resource utilization. Mormon urban space is, as French thinker Henri Lefebvre would suggest, culturally constructed, appropriated and consumed. On a fundamental level, Mormon spaces tack between the extremes of theocracy and secularism, communalism and capitalism and have much to reveal about how Mormonism has defined gender roles and established racial hierarchies. Mormon cultural landscapes both manifest a sense of identity and place, as well as establish relationships with the past. / Dissertation/Thesis / Doctoral Dissertation History 2015

Airborne particulate matter (PM) in urban areas is derived from a combination of natural and anthropogenic sources. To identify PM sources and their effects on air quality, we collected PM using active filter samplers over a two-year period in the urban Wasatch Front, northern Utah, an area affected by multiple pollution sources. Filters from active samplers and other PM samples were analyzed for major and trace element concentrations and 87Sr/86Sr ratios. We identified wind-blown mineral dust from dry lake beds, winter inversions, and fireworks as primary PM sources affecting air quality in the Wasatch Front. Dust contributes Al, Be, Ca, Co, Cs, Fe, Li, Mg, Mn, Rb, Th, U, Y, and REEs which are typical components of carbonate and silicate minerals. Winter inversions entrap As, Cd, Mo, Pb, Sb, Tl, and Zn from brake dust, combustion engine exhaust, and refining processes. Concentrations of common components of fireworks Ba, Cu, K, and Sr greatly increase (>4 times) during holidays. Strontium released from fireworks has a distinct 87Sr/86Sr ratio that dominates the isotopic composition of PM during holidays. Fireworks have 87Sr/86Sr ratios of <0.7080 compared with 0.7100 for Sevier Dry Lake and 0.7150 for Great Salt Lake lakebed. Sources of particulate matter vary seasonally. Dust events dominate the air quality signature during spring and summer while winter inversions occur from November through February. Transport of PM to mountain snowpack negatively affect water quality. This is the first study to describe variations in multiple PM sources and their potential health effects in Utah, USA

The problem of whether Landsat 7 data could be used to delineate areas prone to mass movement, particularly debris flows and landslides, was examined using three techniques: change detection in NDVI (Normalized Difference Vegetation Index), change detection in band 5, and the tasseled cap transformation. These techniques were applied to areas that had recently experienced mass movement: Layton, Davis County and Alpine, Spanish Fork Canyon and Santaquin, Utah County. No distinctive spectral characteristics were found with any of these techniques with two possible explanations: 1. That despite improved spatial resolution in Landat 7 over its predecessors and improved digital image processing capabilities, the resolution is still too low to detect these characteristics or 2. That the aspects of a slope that make it prone to mass movement are undetectable at any resolution by remote sensing. Change detection in NDVI examined if areas that remained unchanged (defined as < 5% change) between August 14, 1999 and October 17, 1999 correlated to areas that are prone to mass movement. There was no correlation. Change detection in band 5 was examined between August 14, 1999 and October 17, 1999, October 17, 1999 and May 28, 2000, and August 14, 1999 and May 28, 2000. An interesting result is that the Shurtz Lake and Thistle landslides (Spanish Fork Canyon) showed changes of greater than 30% during August 14, 1999 - October 17, 1999 and October 17, 1999 - May 28, 2000. These changes were limited to these landslides and not seen in abundance in surrounding areas. A similar localization of 30% change was seen in the Cedar Bench landslide (Layton) for the same time periods. There were no other correlations. The tasseled cap ransformation shows areas of dominate greenness, soil brightness or wetness. None of these factors had distinctive patterns in the areas studied when compared to surrounding, mass movement-prone areas so no conclusions can be drawn about the utility of the tasseled cap transformation as it relates to areas of potential mass movement.
