Terracing, Land Management And Agricultural Soils In The Andagua Valley Of The Southern Peruvian Andes, Blaise Murphy

Electronic Theses and Dissertations

Demographic, socio-political and climatic changes can drastically alter agricultural land management practices, affecting the availability of agriculturally relevant nutrients in the soil. This project investigates the use, reconstruction and abandonment of agricultural terraces and the implications these conditions have on agricultural soil properties of the Andagua Valley in the Western Cordillera of the Southern Peruvian Andes. During the 2016 summer field season, topsoil samples were collected from cultivated and abandoned agricultural terraces between 3229m and 3688m a. s. l. with a range of aspects and ages. Collaboration with a team of archaeologists and anthropologists gave insight into the local and …

The Response Of High Elevation Wetlands To Past Climate Change, And Implications For The Future, Ian Arthur Slayton

Electronic Theses and Dissertations

As part of the ongoing investigation of mid-latitude fens in Colorado by University of Denver paleoenvironment researchers, research directed at examining the response of mid-latitude subalpine fens to past climatic events potentially analogous to modern anthropogenic climate change was undertaken. As part of this research, a 4.18 m sediment core was retrieved from Harbison Pond (2651 m elev) near Grand Lake, CO and a 3.12 m peat core was collected from Whiskey Fen (2792 m elev) in the Never Summer Range. Stratigraphic evidence indicates the kettle lake formed shortly after the Last Glacial Maximum, at least 16,201 cal yr BP …

Exploring Historical Coffee And Climate Relations In Southern Guatemala: An Integration Of Tree Ring Analysis And Remote Sensing Data, Diego Pons

Electronic Theses and Dissertations

This dissertation makes use of a physical geography perspective to examine the relationship between agriculture and climate in Guatemala using dendrochronology. I examined the potential of high-resolution climate proxy data from dendrochronology to help fill in the gaps of past climate information to better understand the natural and anthropogenic variability of precipitation which, in turn, can inform Guatemala’s agriculture sector. This research has demonstrated successful cross-dating and climate sensitivity of Abies guatemalensis in the Pacific slope of Guatemala. Based on this, I have produced a 124-year record of mean precipitation from June-July-August. The mean precipitation from June-July-August at this site …

Ancestral Queerness: Normativity And Deviance In The Abraham And Sarah Narratives, Gil Rosenberg

Electronic Theses and Dissertations

Interpreters of the Abraham and Sarah narratives in Gen 11-21 often focus on the importance of the line of inheritance, through a particular biological child. While they also note the many irregularities in Abraham and Sarah's familial relationships and activities, there has been no sustained attention to the combination of deviance and normativity that characterizes these narratives. I argue that, due to their particular combinations of normativity and deviance, Abraham and Sarah are Queer, where Queer is a general, cross-cultural category which includes but is not limited to contemporary forms of queerness (e.g., lesbian, gay, bisexual, transgender, intersex, etc.).

Using …

Rock Glacier Hydrology In The San Juan Mountains, Colorado, Emilio Ian Mateo

Electronic Theses and Dissertations

Rock glaciers are unique geomorphological features located in alpine environments and are found in the San Juan Mountains of Colorado. There has been little research done on rock glaciers compared to their ice glacier counterparts. Most rock glaciers are located on the northern slope aspect in mountainous areas (Janke 2007), however, there are multiple in southwest Colorado with different aspects. This research project asks how slope aspect influences the hydrological processes of streams sourced from rock glaciers in the San Juan Mountains. This project focused on three basins that are adjacent to each other and share a common peak, Gilpin …

Urban Children's Experience Of A Natural Place Outside Of Denver, Corey J. Martz

Electronic Theses and Dissertations

In the United States, a common and ingrained perception is that humans are separate from nature. Over the last several decades, urbanization, the increasing presence of technology, and progressively busier schedules contribute to a growing concern over a disconnect between children and nature. In light of this potential disconnect, I explored how urban children experience a natural place outside of the city. In this study, I investigated the "sense of place" of 27 children living in Denver, Colorado; sixteen of these children had experienced a natural place at a summer camp outside of the city. The children created photo-story maps …

Effects Of Collaboration Between Speech-Language Pathologists And Third-Grade Teachers On Student Vocabulary Outcomes, Mary Mitchell

Electronic Theses and Dissertations

A persistent literacy crisis continues to be reflected in international (Organisation for Economic Co-operation and Development [OECD], 2013), national (National Center for Education Statistics [NCES], 2015), and local literacy outcome data. Educators, including speech-language pathologists (SLPs), are called upon to collaborate to support students who struggle with academic language/literacy. However, few studies have operationally defined collaboration and investigated the effects of collaboration on student achievement. As a result, there is insufficient guidance for educators about ways to design, implement, and assess the effectiveness of collaboration models, defined in terms of their effects on student outcomes. There were two main objectives …

Medieval Ingenuity In Fourteenth Century English Milling In Middlesex, Norfolk, And Northumberland Counties, Brett Pelham

Electronic Theses and Dissertations

This thesis examines the effect of population losses from outbreaks of the Bubonic Plague on capital investment for labor saving technology in England. The cities in Middlesex and Norfolk advance the economy in their surrounding areas. Northumberland's access to Newcastle-Upon-Tyne did not house as much wealth for Coquetdale and Glendale. However, Edward I's constant investment in the recently acquired Scottish territory provided the area with income from the crown. While the decrease in population was catastrophic and presented social turmoil, the surviving population continued to make economic adjustments. The economic adaptations provided relief to a strained population. Trade should have …

Human Dimensions Of Habitat Loss In The Plains And Prairie Potholes Ecoregion, Lily A. Sweikert

Electronic Theses and Dissertations

The Plains and Prairie Potholes Ecoregion (PPPE), is located in the north-central contiguous United States and is one of the most imperiled grassland regions in the world. Most of the region is privately owned and used for the production of agricultural commodities. In addition to its direct benefits to humanity, the PPPE provides multiple ecosystem services including, soil and water quality improvements, carbon sequestration, weather amelioration, and wildlife habitat. Recent increases in expansion of row crop agriculture concerns conservation practitioners about the long-term integrity of the PPPE. Conservation practitioners are looking to improve their private landowner conservation initiatives in the …

Using Remote Sensing To Estimate Crop Water Use To Improve Irrigation Water Management, Arturo Reyes-Gonzalez

Electronic Theses and Dissertations

Irrigation water is scarce. Hence, accurate estimation of crop water use is necessary for proper irrigation managements and water conservation. Satellite-based remote sensing is a tool that can estimate crop water use efficiently. Several models have been developed to estimate crop water requirement or actual evapotranspiration (ETa) using remote sensing. One of them is the Mapping EvapoTranspiration at High Resolution using Internalized Calibration (METRIC) model. This model has been compared with other methods for ET estimations including weighing lysimeters, pan evaporation, Bowen Ratio Energy Balance System (BREBS), Eddy Covariance (EC), and sap flow. However, comparison of METRIC model outputs to …

Examination Of The Potential Of Structure-From-Motion Photogrammetry And Terrestrial Laser Scanning For Rapid Nondestructive Field Measurement Of Grass Biomass, Sam D. Cooper

Electronic Theses and Dissertations

Above ground biomass (AGB) is a parameter commonly used for assessment of grassland systems. While destructive sampling of AGB is highly accurate, it is time consuming and often precludes repeat temporal sampling or sampling in sensitive ecosystems. Consequently, a number of nondestructive techniques that relate grass structural properties to AGB have been developed. This study investigated the application of two recent technologies, Terrestrial Laser Scanning (TLS) and Structurefrom- Motion (SfM), in the development of rapid nondestructive AGB estimation of grassland plots. TLS and SfM volume metrics generated using a rasterized surface differencing method were linearly related to destructively measured total …

A new analysis workflow is purposed for regression analysis of spatial data. …

Reflection And Acceptance: Small Town Ghosts Represented In Poetry, Adam Junker

Electronic Theses and Dissertations

This thesis discusses the theories of ethnography and ethnographic verse and applies these two theories in an original narrative in verse. Ethnography and ethnographic verse have a complicated relationship when it comes to a poet’s authority representing a certain place. Yet authenticity is never obtainable, since perceptions of a place are always subjective. That subjectivity allows a poet creative expression, as he or she shapes his or her relationship with a place and the people within it. The poet then must rely on elements like unifying imagery, dialect, surrealism, and empathetic insights. With these elements, a poet can identify with …

Land Surface Phenologies And Seasonalities Using Cool Earthlight In Temperate And Tropical Croplands, Woubet Gashaw Alemu

Electronic Theses and Dissertations

In today’s world of increasing food insecurity due to more frequent and extreme events (droughts, floods), a comprehensive understanding of global cropland dynamics is critically needed. Land surface parameters derived from the passive microwave Advanced Microwave Scanning Radiometer on EOS (AMSR-E) and AMSR2 data enable monitoring of cropland dynamics and they can complement visible to near infrared (VNIR) and thermal infrared (TIR) data. Passive microwave data are less sensitive to atmospheric effects, cloud contamination, and solar illumination constraints resulting in finer temporal resolution suitable to track the temporal progression of cropland cover development compared to the VNIR data that has …

Creating A Stormwater Runoff Model For The City Of Oxford, Mississippi: When It Rains, Where Does That Water Go?, Alexandra Gay Weatherwax

Electronic Theses and Dissertations

The city of Oxford, Mississippi (home of the University of Mississippi) has experienced, in recent years, a rapid growth of urbanization. This rapid increase creates more impervious cover, such as bridges, roads, parking lots, etc., which can cause a stress on the capacity of stream load and causes flooding. To correct this, storm water management is needed in the city. This stormwater runoff model uses data collected from rain gauges, soil data from ssurgo and published soil infiltration rates from a Lafayette County soil survey, impervious cover created from Lidar and Aerial Photography, published evapotranspiration rates, and storm drain locations …

Three Essays On Private Market Interactions, Jonathan Daigle

Electronic Theses and Dissertations

The first study addresses why insurers, whom traditionally invest in relatively safe assets, choose to invest in private equity (PE). Using insurer financial disclosures, we test theories relating how risk shifting, managerial discretion, underinvestment, asset liability matching, regulation, home bias, and reaching for yield affect PE investment. Results indicate risk¬ shifting and managerial discretion by stock insurers does not factor into the PE investment decision. In addition, results confirm home bias positively influences PE investment while underinvestment, asset liability matching, and regulation deter PE investment. Finally, insurers have not increased their PE allocation due to low-yield interest rate environments. The …

This paper utilizes the survey data from China Health and Nutrition Survey in 2011. The methods of descriptive statistics, correlation, and stepwise multiple regression models are applied in analyzing the data. The results …

Normalization Of Pseudo-Invariant Calibration Sites For Increasing The Temporal Resolution And Long-Term Trending, Harika Vuppula

Electronic Theses and Dissertations

Given their low level of temporal, spatial, and spectral variability, Pseudo-Invariant Calibration Sites (PICS) have been increasingly desired as data sources for radiometric calibration of Earth imaging satellite sensors. The temporal resolution for PICS data acquired by any sensor is limited by the amount of time required for it to make subsequent passes over the site. Consequently, for any given PICS, it can take many years of imaging to develop a sufficient amount of cloud-free data to perform radiometric calibration; this can be especially problematic for sensors in their early years after launch. This thesis presents techniques to combine Landsat-8; …

Object Of Your Rejection: The Symbolic Annihilation And Recuperation Of Queer Identities In Country Music, Lauren Veline

Electronic Theses and Dissertations

This thesis addresses the double-marginalization of white queers living in Bible Belt communities by examining the symbolic annihilation of queer identities in country music. Bible Belt queers face unique obstacles and have different needs than queer communities elsewhere due to the cultural context of their communities. The urban-centric (“metronormative”) standards of queer identity and visibility presented in the media do not translate to their lived experiences. Moreover, while white, non-urban southerners possess a source of popular-media expression through country music, queer identities are noticeably absent. The invisibility of Bible Belt queers in the media perpetuates a cycle of hostility and …

Risk, Reward, And The Role Of Habitat Selection On Community Dynamics In Temporary Ponds, Matthew Robert Pintar

Electronic Theses and Dissertations

The processes that generate patterns of species diversity within and among habitat patches are a fundamental topic of interest in ecology. Traditionally, there was a focus on post-colonization effects such as predation, however, pre-colonization processes, such as habitat selection, are equally important determinants of community structure. In freshwater systems, the lethal effects of dominant predators (particularly fish) are well established, while the transition from permanent to temporary ponds is a defining characteristic. This transition produces distinct communities characterized by organisms with complex life cycles and plastic developmental strategies. This means that many organisms occupying habitat patches arrive there by the …

Black Space On A White Campus; Exploring The Relationship Between African American Students And The Physical Structure Of The University Of Mississippi, Drew Ford

Electronic Theses and Dissertations

At the University of Mississippi, despite institutional efforts to distance the present from the past, issues of race continue to influence the campus and the experiences of African-American students. This thesis examines the relationship between the physical structure of the university of Mississippi campus and African American students, and investigates the creation of "counter-publics." this thesis analyzes works in critical race theory, higher education, and social geography to argue that the "whiteness" of the university of Mississippi campus creates social and educational barriers for African American students. Furthermore, along with being surrounded by "whiteness," African American students lack any physical …

Historical Refuges And Recolonization Routes In The Southern Appalachian Mountains, Inferred Through Phylogeographic Analysis Of The Spotted Wintergreen (Chimaphila Maculata), John Daniel Banusiewicz

Electronic Theses and Dissertations

Phylogeography has recently benefited from incorporation of coalescent modeling to test competing scenarios of population history of a species. Ecological niche modeling has also been useful in inferring areas of likely suitable habitat during past climate conditions. Several studies have examined the population history of biota in the Southern Appalachian Mountains and how they responded to climate change associated with the end of the Last Glacial Maximum (~18,000 years ago), though few studies have focused on understory plants. This study redressed that knowledge gap thorough examination of the phylogeographic history of the understory plant Chimaphila maculata, which is native to …

Universal Principles Of Bioethics And Patient Rights In Saudi Arabia, Ahmed Abdulbasit Bukhari

Electronic Theses and Dissertations

In order to keep pace with international bioethical practices, and with international bioethical declarations, this dissertation will investigate challenges facing patients’ rights discourse in Saudi Arabia, and the adaptation of universal bioethics standards in the Saudi healthcare system. The role of religion and issues of human rights will be discussed further, given that religion and human rights affect patient’s rights profoundly. Specifically, the divergence between religious dictations and the secular language of human rights principles will provide a distinctive perspective on patients’ rights discourse, especially in a country such as Saudi Arabia where religion is integral to the national foundations, …

The Analysis Of Contact-Era Settlements In Clay, Lowndes, And Oktibbeha Counties In Northeast Mississippi, Emily Lee Clark

Electronic Theses and Dissertations

The goal of this project is to compare the spatial distribution of sites across Clay, Lowndes, and Oktibbeha counties between the Mississippi and Early Historic periods using site files from the Mississippi Department of Archives and History. Using Geographic Information Systems (GIS), sites were mapped chronologically to examine change through time to investigate how people reacted to European contact and colonization. Site locations and clusters also were used to evaluate possible locations of the polities of Chicaza, Chakchiuma, and Alimamu discussed in the De Soto chronicles. Sites in Clay, Lowndes, and Oktibbeha counties were chosen due to the existence of …

Scientific Transformations: A Philosophical And Historical Analysis Of Cosmology From Copernicus To Newton, Manuel-Albert Castillo

Electronic Theses and Dissertations

The purpose of this thesis is to show a transformation around the scientific revolution from the sixteenth to seventeenth centuries against a Whig approach in which it still lingers in the history of science. I find the transformations of modern science through the cosmological models of Nicholas Copernicus, Johannes Kepler, Galileo Galilei and Isaac Newton. Since of the enormous content, I shall only pay particular attention to Copernicus and Newton in which the emerging sciences transformed the cosmos on what Alexandre Koyré calls from a "closed world to infinite universe". As an interdisciplinary approach, I used the methods and inquiries …

Cafeteria Culture: An Anthropological Approach To Lunchtime In A Central Florida Elementary School, Emily Herrington

Electronic Theses and Dissertations

Public school cafeterias are used by nearly 51 million children (ages 4-17) in the United States every day. With over 40% of the approximately 73 million children (ages 0-17) participating in the National School Lunch Program (NSLP), public school lunches carry resounding nutritional, social, and educational significance for their consumers. This fact, coupled with frequent media attention to school lunch food, notwithstanding, a notable lack of social scientific engagement with both students' perspectives and NSLP operators persists. Divided into two studies, this research utilizes ethnographic methods to explore students' lunchtime experiences within a Central Florida public elementary school cafeteria. Both …

Against The Flow: A Nineteenth Century Watermill In Central Florida, Elizabeth Chance Campbell

Electronic Theses and Dissertations

Small community watermills in Central Florida have gone virtually undocumented archaeologically and little is known about them except for written historical accounts. In an effort to determine how a settler in 1866 Florida would have used prior technological knowledge to design, build, and use a watermill I used a GIS predictive model to locate a previously undocumented watermill built in what is now Seminole County Florida. After the mill was located, excavations were conducted to determine the size of the mill structures, the industrial capacity of the mill, and determine the construction methods employed to build the mill.

Youth Labor Market Conditions And The Neet Population In The Eu: Do Poor Labor Market Opportunities Discourage Youth?, Jennifer Hudson

Electronic Theses and Dissertations

This study examines how poor labor market opportunities discourage youth between the ages of 15 and 24 and 15 to 29 from participating in the labor market in the European Union between 2005 and 2013. A critical portion of inactive NEETs (youth not in employment, education, or training) reports to be discouraged due to a recognized "lack of opportunities in the labor market." Despite indications from descriptive analyses that the conditions that drive the distinct subsets of the NEET population vary, empirical examinations of the effects of these conditions on the rates of different NEET groups across countries and over …

The Paths Less Traveled: Movement Of Gopher Tortoises Along Roads And Railways, Rhett Rautsaw

Electronic Theses and Dissertations

Urbanization and an expanding human population have led to a large degree of habitat destruction and fragmentation. These, in turn, reduce biodiversity and wildlife population sizes on a global scale. Transportation infrastructure, such as roads and railways, are some of the largest contributors to habitat fragmentation. Roads are well-established to negatively impact wildlife, but some studies suggest a potential use in habitat connectivity by functioning as wildlife corridors to connect distant populations. Railways are similarly known to impact wildlife by increasing mortality rates as well as provide unique risks such as electrocution and entrapment when compared to roads. However, the …
