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 …
Encouraging Organic Agriculture: The Effects Of Conversion Subsidies, Sarah Adams Inkoom
Encouraging Organic Agriculture: The Effects Of Conversion Subsidies, Sarah Adams Inkoom
Electronic Theses and Dissertations
This thesis examines the importance of conversional subsidies in accounting for an increase in organic acreage in the 12 North-Central States in the United States. Monthly time series data that spans from January 2002 to December 2014 was used in the analysis. Empirical evidence suggests that increase in organic acreage is due in part to the availability of conversion subsidies. Without government assistance, most small-scale farmers are not sufficiently motivated to switch to organic production due to the high initial costs involved in transitioning. Further, increased institutional support could facilitate organic adoption and its absence is detrimental to increasing the …

Relationship Of Stress, Sleep, Physical Activity, And Food Insecurity On Eating Behaviors And Obesity, Amy Lee Richards
Electronic Theses and Dissertations
There is an urgent need to find effective interventions to prevent and reduce obesity as it is associated with chronic disease and decreased quality of life. Gaining a better understanding of how modifiable variables such as stress, sleep, physical activity, and food insecurity are related to eating behaviors associated with obesity is essential to guide the direction of future interventions and research. Interventions that hold promise need to be tested to determine if they have merit or not. This dissertation presents three papers. Two papers are cross-sectional studies evaluating associations between eating behaviors, obesity, and modifiable variables (stress, sleep, physical …
The Fiscal Theory Of The Price Level In Sub-Saharan Africa: A Structural Break Analysis, Christian Tchamda
The Fiscal Theory Of The Price Level In Sub-Saharan Africa: A Structural Break Analysis, Christian Tchamda
Electronic Theses and Dissertations
In this paper, I provide empirical evidence of the fiscal theory of the price level (FTPL) using sub-Saharan African countries. While the traditional view of the inflation is driven and explained by the quantity theory of money, the FTPL argues that the government deficit has an impact on the price level. However, the empirical literature of the FTPL is not extensive. This paper adds to this literature in that it substantiates this theory. I determine using primary balance and liabilities data when available to classify a country as under either a monetary dominant regime (the traditional view) or under a …
Price Discovery And Volatility Spillover Effects: The Agricultural Etps And Their Underlying Commodities, Yu Chen
Electronic Theses and Dissertations
This thesis investigates the price discovery and volatility spillover effects between agricultural ETPs and commodity underlying. We analyze historical prices of five most popular grain ETPs and their underlying commodities using VEC model and BEKK model. Price discovery is confirmed by bidirectional relationships between ETPs and underlying commodity in the long term, and the WEAT_ETP and CBOT Wheat Futures December Contracts. In addition, findings show unidirectional relationships between ETPs and underlying, mostly in the short term. In the process of price discovery, the information share of ETPs is much lower than that of underlying, with a potential downward trend. Volatility …
Factors Affecting Feedlots' Decisions On Cattle Marketing Options: A National Study, Charlotte Owusu-Smart
Factors Affecting Feedlots' Decisions On Cattle Marketing Options: A National Study, Charlotte Owusu-Smart
Electronic Theses and Dissertations
This thesis investigates the economic implication of changing slaughter volume patterns across the cash and contract markets in the US cattle industry. Weekly time series data that spans from November 2002 to December 2015 was used in the analysis. Empirical evidence suggests that Mandatory Price Reporting (MPR) played an important role in changing slaughter volumes across the cash and contract markets. Additionally, price of feeder cattle, cattle quality characteristics (Choice-Select spread and the percentage of animals grading choice or better) among others influence feedlots’ decision to use a particular marketing arrangement.

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 …

Account Service And Creative Personnel: Interpersonal Conflict And Dialectical Tensions In Advertising Agencies, Ashley Phillips
Electronic Theses and Dissertations
Account service and creative personnel have oppositional perspectives and motivations that often lead to interpersonal conflicts while working together on client projects. The purpose of this study was to explore the nature of interpersonal conflicts in advertising agencies. The researcher used relational dialectics theory as a lens for analyzing the dialectical (i.e., oppositional) tensions experienced by account service and creative personnel as well as the praxis patterns (i.e., techniques) used to manage those tensions. After conducting in-depth interviews with five account service and five creative personnel (N = 10) from full service advertising agencies in the Midwest, an analysis revealed …
Funding Of Higher Education: Variations In State Funding, Impacts Of State Funding On Differential Tuition, And Variables Impacting Differential Tuition, Michael Holbeck
Funding Of Higher Education: Variations In State Funding, Impacts Of State Funding On Differential Tuition, And Variables Impacting Differential Tuition, Michael Holbeck
Electronic Theses and Dissertations
Public higher education in the United States has seen many changes since the Morrill Act of 1862. Specifically, the funding of higher education has changed greatly over the last half century, from very low tuition and relatively high state subsidies to an increased reliance on tuition to fund higher education. While this funding change has been the national trend, the impact on specific states and universities has varied greatly. This study examines the funding variation between university peers, normalized using state general funds per resident student FTE, to analyze the variation of state funding between states as well as the …
Rewiring The Anger: Learning New Responses In The Therapeutic Community, Emma Marie Burleson
Rewiring The Anger: Learning New Responses In The Therapeutic Community, Emma Marie Burleson
Electronic Theses and Dissertations
Extensive research has been conducted in correctional settings on the effects that therapeutic programs that utilize cognitive-behavioral therapies have on recidivism rates and cognitive-behavioral changes among inmates. Research on anger management programs in correctional settings has shown that there are measurable effects on the anger levels of participants based on quantitative pre-testing and post-testing. The present study sought to build on this research in a unique way by conducting qualitative research to examine the personal perceptions of inmates that have graduated from a therapeutic program in a maximum security prison. The study focused on participants’ perceived changes in how they …

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 …

Employees’ sex, disaster experience, impact of that experience, perceived threat, and self-efficacy were examined as predictors of actual preparedness, across a range of natural disasters and incidents of mass violence. Drawing from the Extended Parallel Process Model (EPPM; Figure 1), a moderated mediation model (Figure 2) was …
Three Essays On Private Market Interactions, Jonathan Daigle
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 …

An Analysis Of Factors Affecting Bid Of Infant-Formula Manufacturers In Wic Rebate Auctions, Raymond Opoku
Electronic Theses and Dissertations
This thesis investigates the factors that affect bid decisions of infant-formula manufacturers in WIC rebates auctions. Since its inception in 1972, the WIC program has served more than half of participating women and their infants each year. Today, Infant formula - the most expensive food item on the WIC menu - is accessible to all participants for free through the WIC rebate program. Through the rebate program, firms submit bids to solely supply their infant formula to a state WIC agency at a discount leading to fall in net prices. Yet, the firms in the infant formula market are selective …

Measuring Central Bank Credibility From The Effect Of Inflation Shocks On Asset Prices, Junmei Xu
Measuring Central Bank Credibility From The Effect Of Inflation Shocks On Asset Prices, Junmei Xu
Electronic Theses and Dissertations
In the early 1990s, the Bank of Canada explicitly adopted the inflation-targeting framework for monetary policy, while the Federal Reserve did not; instead, the Fed settled on an implicit inflation-targeting framework. In this study, I test whether the Bank of Canada and the Federal Reserve earned credibility for their respective commitments— explicit or otherwise—to maintain low and stable inflation. I model how credibility shapes the responses of asset prices to inflation shocks. And, for each country, I estimate responses of commodity and foreign exchange prices to announcements of inflation shocks during the periods of 1982 to 1991 (pre-inflation targeting period) …

Funny In A Man's World: Women Comedians' Use Of Political Satire At The White House Correspondents' Dinner, Jessica M. Peterson
Electronic Theses and Dissertations
Satire and politics are typically considered masculine fields within the societal constructs of the United States. Wanda Sykes and Cecily Strong both navigate these male-dominated worlds with their addresses at the White House Correspondents’ Dinner. This analysis views these addresses through three rhetorical lenses: feminist standpoint theory, rhetorical citizenship, and rhetorical and political agency. This study explores the way women’s issues in society exposed to various audiences through Sykes’ and Strong’s satirical addresses. Communication scholars have not previously considered both of these addresses; this analysis furthers our understanding of feminist viewpoints being shared to audiences and encouraging audiences to take …
The Syrian Refugee Crisis: A Rhetorical Analysis Of President Barack Obama, Hillary Clinton, And President Donald J. Trump’S Political Discourse About Syrian Refugees, Erin Lionberger
Electronic Theses and Dissertations
In this thesis, I introduce the reader to sixteen texts of political discourse about Syrian refugees from three rhetors; President Barack Obama, Hillary Clinton and President Donald J. Trump. As the Syrian refugee crisis continues to grow, political leaders and citizens around the world debate the appropriate way to provide aid to those fleeing Syria. I rhetorically analyze multiple texts from each of these politicians’ and their use of framing, ideographs and metaphors within their political discourse. In my research, I suggest that the framing language used by each rhetor about Syrian refugees has varying impacts on the audience. The …

Do College Students Perceive Stigma The Same Way Experts Do? An Experimental Test Of Lay Perceptions Of Body-Size Stigma, Andie Malterud
Electronic Theses and Dissertations
Personal experience with weight-based stigma is negatively associated with selfesteem (Myers & Rosen, 1999). This study examined how self-esteem is affected by exposure to weight-based stigma communication that is directed at another person. Using Smith’s (2007a) stigma communication framework, I created a 2 (Stigma Level: high, low) x 2 (Gender of stigmatized person: male, female) x 2 (Body Size of stigmatized person: large, small) posttest-only experiment. Participants’ self-esteem was not impacted after viewing stigmatizing messages directed at another person. This suggests that selfesteem is more stable than some researchers indicate (Wagner, Lüdtke, and Trautwein, 2016). My results suggest that stigma …

Heterogeneous Nitrogen Losses: Cost-Effectiveness Analysis Of Changes In Management Across South Dakota, Archibold Quaye
Electronic Theses and Dissertations
The loss of nitrogen fertilizer into the atmosphere and waterways is of increasing concern for citizens and policy makers. This is particularly relevant for hypoxia in rivers, lakes, and oceans, but also relevant for policy makers in reducing the increasing concentration of greenhouse gases (GHG) in the atmosphere. GHGs trap heat in the atmosphere and include: carbon dioxide, methane, nitrous oxide and fluorinated gases. Overall, the estimated contribution from the agricultural sector to GHG emissions was 9% in 2013 (EPA, 2013). Further, the addition of nitrogen to the soil through the use of synthetic fertilizers is a main contributor to …
Exploring The Relationship Between Immediacy Behaviors And Student Motivation In Engineering Classrooms: Immediacy As A Cause Of Motivation, Andrea N. Barahona Guerrero
Exploring The Relationship Between Immediacy Behaviors And Student Motivation In Engineering Classrooms: Immediacy As A Cause Of Motivation, Andrea N. Barahona Guerrero
Electronic Theses and Dissertations
Instructor immediacy is an essential characteristic of effective instructors. Although instructional communication has done extensive research on the impact of immediacy behaviors on students, there is little available research observing immediacy behaviors as predictors of motivation on engineering students. As a result, this study examined the impact of engineering instructors’ use of immediacy behaviors on engineering students’ motivation. The results indicated that verbal immediacy predicted engineering student motivation. The thematic analysis revealed that when students perceived their instructors as helpful, students’ motivation to learn and ask more questions increased. The thematic analysis also observed that when instructors seemed unapproachable, students …
Normalization Of Pseudo-Invariant Calibration Sites For Increasing The Temporal Resolution And Long-Term Trending, Harika Vuppula
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; …
