Homo Religiosus? Religion And Immigrant Subjectivities, David Ley, Justin Kh Tse Sep 2013

Homo Religiosus? Religion And Immigrant Subjectivities, David Ley, Justin Kh Tse

Research Collection School of Social Sciences

Once ignored in national and international public policy, religion has made a comeback as policymakers have noticed the significance of the resurgence of religion, especially due to migration flows. While laudatory of these developments, this chapter specifies the need for a theological reading of the migrant religious practitioner as homo religiosus. First, we describe the social geographies of immigrant religion in an international context, drawing attention to the vibrancy of religious devotion, especially Christianity from the global south, among migrant groups. Second, we re-conceptualise religious belief through the theoretical work of John Milbank and Charles Taylor as they recuperate a …

Dendrochronology: Exploring Land Use In Montezuma Canyon, Julia Matheny, Dr. Matthew Bekker Sep 2013

Dendrochronology: Exploring Land Use In Montezuma Canyon, Julia Matheny, Dr. Matthew Bekker

Journal of Undergraduate Research

Montezuma Canyon, of San Juan County, Utah has a long and rich history of human occupation with land use by various peoples. The Anasazi occupied the area from 200 to 1300 A.D., at which time the area was abandoned. Euroamerican pioneers came into the canyon in the 1880’s and introduced domestic cattle, which promoted grazing into the area. Since the time of Euroamerican settlement, the landscape of Montezuma Canyon has undergone dramatic changes due to erosion. Grazing, along with various other land uses involved in ranching and farming, have been suggested as possible causes of erosion, loss of viable soils …

Reducing The Cost Of Soil Mapping In Precision Agriculture, Elizabeth Gillins, Dr. Ruth Kerry Sep 2013

Reducing The Cost Of Soil Mapping In Precision Agriculture, Elizabeth Gillins, Dr. Ruth Kerry

Journal of Undergraduate Research

Using electrical conductivity data (ECa) in soil survey is related to several soil properties. Particular use has been made of ECa data in precision agriculture because it is related to properties that could affect crop yield. Although theoretically sound reasons exist to explain these relationships, they vary spatially, making ECa data interpretation difficult, even within fields.

Intermittence For Humans Spreading 45,000 Years Ago: From Eurasia To The Americas, J. C. Flores Sep 2013

Intermittence For Humans Spreading 45,000 Years Ago: From Eurasia To The Americas, J. C. Flores

Human Biology Open Access Pre-Prints

From northeastern-Eurasia to the Americas, a three stage spread of Modern Humans is considered through large scale intermittence (exploitation/relocation). Conceptually, this work supports intermittence as a real strategy for colonization of new habitats. For the northeastern Eurasia travel, the first stage, we adapt our model to archaeological dates determining the diffusion coefficient (exploitation phase) as D=299.44 [km2/yr] and the velocity parameter (relocation phase) as vo=4.8944 [km/yr]. The relative phaseweight (≈ 0.46), between both kind of motions, is consistent with a moderate biological population rate (r'≈ 0.0046 [1/yrs]). The second stage is related to population …

Mapping Disease At An Approximated Individual Level Using Aggregate Data: A Case Study Of Mapping New Hampshire Birth Defects, Xun Shi, Stephanie Miller, Kevin Mwenda, Akikazu Onda Sep 2013

Mapping Disease At An Approximated Individual Level Using Aggregate Data: A Case Study Of Mapping New Hampshire Birth Defects, Xun Shi, Stephanie Miller, Kevin Mwenda, Akikazu Onda

Dartmouth Scholarship

Limited by data availability, most disease maps in the literature are for relatively large and subjectively-defined areal units, which are subject to problems associated with polygon maps. High resolution maps based on objective spatial units are needed to more precisely detect associations between disease and environmental factors. Method: We propose to use a Restricted and Controlled Monte Carlo (RCMC) process to disaggregate polygon-level location data to achieve mapping aggregate data at an approximated individual level. RCMC assigns a random point location to a polygon-level location, in which the randomization is restricted by the polygon and controlled by the background (e.g., …

Uncertainty Analysis Of The Large Zone Economic Module (Lzem) Of The Se3m Model Of Land Use And Transportation, Alex Norr, Dr. Michael Clay

Journal of Undergraduate Research

Integrated land use and transportation forecasting models are used to assist decision makers in the policy analysis and infrastructure capital improvements selection process (1, 2, and 3). These models are typically given precise, point-estimate inputs that are mathematically linked, through a series of submodels, to forecasted model outputs (4 and 5). These point-estimate inputs represent an unrealistic level of precision and a growing body of research is focusing on statistical techniques to model uncertainty in model inputs and parameters and tracking the effects of this uncertainty through the various submodels to the model outputs (see 4, 6, and 7 and …

Examining Links Between The Lds Faith And Cervical Cancer Mortality Rates Of The American West, Austin Parker, Dr. Ruth Kerry Sep 2013

Examining Links Between The Lds Faith And Cervical Cancer Mortality Rates Of The American West, Austin Parker, Dr. Ruth Kerry

Journal of Undergraduate Research

Several medical geography studies have identified Utah as an outlier in terms of various illnesses with far lower rates than other states in the country. Gooaverts (2009) noticed small clusters of low cervical cancer rates in Utah compared to other states, although he wasn’t specifically studying the heavy LDS influence on Utah’s population. Lower cervical cancer rates in Utah could be attributed to the LDS “Law of Chastity”, which discourages sexual relationships outside of marriage as up to 99% of cases of cervical cancer have been linked to the human papilloma virus, a sexually transmitted disease (http://www.cancerrecovery.org.uk/cervical-cancer). A goal of …

Correlation Of Hyperspectral Bands From Remotely Sensed Imagery And Urban Leaf Area Index, Derek Farnes, Dr. Ryan Jensen Sep 2013

Correlation Of Hyperspectral Bands From Remotely Sensed Imagery And Urban Leaf Area Index, Derek Farnes, Dr. Ryan Jensen

Journal of Undergraduate Research

As the world’s urban population continues to grow, more and more attention is being given to the environment in which humans live – urban areas. Unfortunately, urban expansion often leads to considerable loss of urban forest and its associated amenities. When studying the urban forest, a critical biophysical variable to consider is leaf area index (LAI) which is defined as the ratio of leaf surface area divided by ground area. Due to the importance of this variable, efficient methods have been sought for estimating LAI in urban areas. Potential has been found in measuring LAI with a hyperspectral sensor using …

The Mayaarch3d Project: A 3d Webgis For Analyzing Ancient Architecture And Landscapes, Jennifer Von Schwerin, Heather Richards-Rissetto, Fabio Remondino, Giorgio Agugario, Gabrio Girardi Sep 2013

The Mayaarch3d Project: A 3d Webgis For Analyzing Ancient Architecture And Landscapes, Jennifer Von Schwerin, Heather Richards-Rissetto, Fabio Remondino, Giorgio Agugario, Gabrio Girardi

Department of Anthropology: Faculty Publications

There is a need in the humanities for a 3D WebGIS with analytical tools that allow researchers to analyze 3D models linked to spatially referenced data. Geographic Information Systems (GIS) allow for complex spatial analysis of 2.5D data. For example, they offer bird’s eye views of landscapes with extruded building footprints, but one cannot ‘get on the ground’ and interact with true 3D models from a pedestrian perspective. Meanwhile, 3D models and virtual environments visualize data in 3D space, but analytical tools are simple rotation or lighting effects. The MayaArch3D Project is developing a 3D WebGIS—called QueryArch3D—to allow these two …

Mobile 2d And 3d Spatial Query Techniques For The Geospatial Web, Junjun Yin Sep 2013

Mobile 2d And 3d Spatial Query Techniques For The Geospatial Web, Junjun Yin

Doctoral

The increasing availability of abundant geographically referenced information in the Geospatial Web provides a variety of opportunities for developing value-added LBS applications. However, large data volumes of the Geospatial Web and small mobile device displays impose a data visualization problem, as the amount of searchable information overwhelms the display when too many query results are returned. Excessive returned results clutter the mobile display, making it harder for users to prioritize information and causes confusion and usability problems. Mobile Spatial Interaction (MSI) research into this “information overload” problem is ongoing where map personalization and other semantic based filtering mechanisms are essential …

Design And Interpretation Of Intensity Analysis Illustrated By Land Change In Central Kalimantan, Indonesia, Robert Gilmore Pontius, Yan Gao, Nicholas M. Giner, Takashi Kohyama, Mitsuru Osaki, Kazuyo Hirose

Geography

Intensity Analysis has become popular as a top-down hierarchical accounting framework to analyze differences among categories, such as changes in land categories over time. Some aspects of interpretation are straightforward, while other aspects require deeper thought. This article explains how to interpret Intensity Analysis with respect to four concepts. First, we illustrate how to analyze whether error could account for non-uniform changes. Second, we explore two types of the large dormant category phenomenon. Third, we show how results can be sensitive to the selection of the domain. Fourth, we explain how Intensity Analysis' symmetric top-down hierarchy influences interpretation with respect …

Measuring The Temporal Instability Of Land Change Using The Flow Matrix, D. S.M. Runfola, Robert Gilmore Pontius Sep 2013

Measuring The Temporal Instability Of Land Change Using The Flow Matrix, D. S.M. Runfola, Robert Gilmore Pontius

Geography

This article introduces the Flow matrix, which expresses the sizes of transitions among categories between two time points. We use the Flow matrix to create a metric R that measures the instability of annual change among time intervals that partition the time extent. Specifically, R is the proportion of change that would need to be reallocated to different time interval(s) to achieve uniform change during the time extent. This article computes R for 10 Long Term Ecological Research (LTER) sites and for seven case studies from published land change data. Of the 10 LTER sites analyzed, the Andrews site in …

Using Dendrochronology To Identify An Unknown Earthquake, Douglas Metcalf, Dr. Matthew Bekker Aug 2013

Using Dendrochronology To Identify An Unknown Earthquake, Douglas Metcalf, Dr. Matthew Bekker

Journal of Undergraduate Research

Geologists use various dating techniques to determine the ages of geologic phenomena. Dendrochronology- the analysis of annual growth-rings in trees- is one of these methods (Stoffel and Bollschwieler, 2008). Unlike other dating procedures, it can determine the exact years in which various events occurred. Such events include earthquakes, which produce distinct responses in tree-ring growth patterns (Jacoby, 1997).

Dendroarchaology: Using Tree Rings To Document Utah’S Historic Pioneer Structures, Robert Karl, Dr. Matthew Bekker Aug 2013

Dendroarchaology: Using Tree Rings To Document Utah’S Historic Pioneer Structures, Robert Karl, Dr. Matthew Bekker

Journal of Undergraduate Research

Pioneer history is a heritage of Utah. Utah was founded on the premise of pioneers venturing from the east and settling throughout Utah. Very few of these historic pioneer structures have been dated in the state of Utah and for many of these structures there exists only a rough idea of when they were built. Other structures have been dated but the information is unpublished and therefore unavailable to the general public and the scientific community. And, though the use of tree rings in archaeology has a rich history in the southwestern United States , most research has focused on …

Trends In The Spatial Distribution And Characteristics Of Korean-Americans, Megan Knowles, Dr. J. Matthew Shumway, Ruth Kerry Aug 2013

Trends In The Spatial Distribution And Characteristics Of Korean-Americans, Megan Knowles, Dr. J. Matthew Shumway, Ruth Kerry

Journal of Undergraduate Research

In Human Geography minimal research has been done regarding the immigration and spatial distribution of Korean-Americans. Historically there has been a detectable relationship between the degree of spatial concentration of a specific population and their degree of social assimilation. Few studies have been conducted regarding Korean-Americans as a separate ethnic group, and these studies most often focus on economic, health, and cultural aspects of the community and tend to be more local in scale.

A Paleoenvironmental Investigation Of Eolian Influx In Lacustrine Sediments Of The Southern Rocky Mountain Region, Rebecca L. Brice

Electronic Theses and Dissertations

Potential indications of long-term trends in paleoclimate, specifically winds, in the Southern Rocky Mountain region of the United States were tested using lacustrine sediment from South Blue Lake in the Wet Mountains of Colorado. This study builds upon existing eolian and lacustrine research, and investigates paleowind in a location not yet studied in this manner. Variability in sediment laminae, particle size, and mineralogy show similar patterns during the mid-Holocene warm period (ca. 5500 cal. yr BP - ca. 6000 cal. yr BP). These patterns indicate a warmer, drier, windier period that is contrasted by a less variable period in the …

The Use Of The Ostracode Cyprideis Americana (Sharpe) As A Proxy For Salinity In Bahamian Lake Systems, Rachel E. Bowles Aug 2013

The Use Of The Ostracode Cyprideis Americana (Sharpe) As A Proxy For Salinity In Bahamian Lake Systems, Rachel E. Bowles

Masters Theses & Specialist Projects

Ostracodes, bi-valved crustaceans, are potentially excellent proxies for salinity.They are abundant, react to changes in salinity, and secrete low-magnesium calcite shells that preserve information about their host water chemistry. Changes in valve trace element concentration, stable isotope composition, and sieve pore shape values have been linked to changes in salinity. This study analyzed the response of the euryhaline ostracode, Cyprideis americana, to salinity in six lakes from two Bahamian islands across two seasons. The purpose of this work was to determine which compositional and morphological variables in C. americana are the most useful for paleosalinity reconstructions.Ostracode and water samples were …
