Evaluating And Improving Consumer Perceptions Of The Agriculture Industry, Katelyn Berndt Jan 2019

Evaluating And Improving Consumer Perceptions Of The Agriculture Industry, Katelyn Berndt

Schultz-Werth Award Papers

Consumer perceptions of the agriculture industry are increasingly important as alternative labeling and non-conventional options become more common.

The Economic And Social Values Associated With Small South Dakota Lakes, Aaron Patrick Sundmark Jan 2019

The Economic And Social Values Associated With Small South Dakota Lakes, Aaron Patrick Sundmark

Electronic Theses and Dissertations

The valuation of small fishing lakes is a vital component in understanding the importance of fishing and of recreational resources, in general. Knowing the values associated with such lakes is essential when prioritizing management activities. The overall value of a lake as a resource for human benefit is estimated as the summation of both instrumental and non-instrumental values. Instrumental values consist of economic and utilitarian values, as well as the values that a lake provides from ecosystem services. Non-instrumental values consider what the lake is worth as a good of its own, such as aesthetic, moral, and spiritual values gained …

Characterizing Spatiotemporal Patterns Of White Mold In Soybean Across South Dakota Using Remote Sensing, Confiance L. Mfuka

Electronic Theses and Dissertations

Soybean is among the most important crops, cultivated primarily for beans, which are used for food, feed, and biofuel. According to FAO, the United States was the biggest soybeans producer in 2016. The main soybean producing regions in the United States are the Corn Belt and the lower Mississippi Valley. Despite its importance, soybean production is reduced by several diseases, among which Sclerotinia stem rot, also known as white mold, a fungal disease that is caused by the fungus Sclerotinia sclerotiorum is among the top 10 soybean diseases. The disease may attack several plants and considerably reduce yield. According to …


Augmenting Land Cover/Land Use Classification By Incorporating Information From Land Surface Phenology: An Application To Quantify Recent Cropland Expansion In South Dakota, Lan Hoang Nguyen Jan 2019

Augmenting Land Cover/Land Use Classification By Incorporating Information From Land Surface Phenology: An Application To Quantify Recent Cropland Expansion In South Dakota, Lan Hoang Nguyen

Electronic Theses and Dissertations

Understanding rapid land change in the U.S. NGP region is not only critical for management and conservation of prairie habitats and ecosystem services, but also for projecting production of crops and biofuels and the impacts of land conversion on water quality and rural transportation infrastructure. Hence, it raises the need for an LCLU dataset with good spatiotemporal coverage as well as consistent accuracy through time to enable change analysis. This dissertation aims (1) to develop a novel classification method, which utilizes time series images from comparable sensors, from the perspective of land surface phenology, and (2) to apply the land …


Investigation Of Intergroup Bias In Two Neuromaturationally Distinct Age Cohorts: An Erp Study, Reuven M. Hanna Jan 2019

Investigation Of Intergroup Bias In Two Neuromaturationally Distinct Age Cohorts: An Erp Study, Reuven M. Hanna

Electronic Theses and Dissertations

Currently, sociological investigation of adolescent behavior focuses on the intersection of biography, history, and structure to explain adolescent risk-taking, reward-seeking, impulsivity, novelty-seeking and peer-salience. However, the preponderance of the evidence points away from social ecology and to a significant neuromaturational restructuring event between the 12th and 25th years of life as the root of adolescent behavioral tendencies. As a result, sociological social psychology can benefit from engaging in basic research using neuroscience methods. The present study expands the dual systems model of brain development to account for maturational changes in the social brain network as a way to explain social …

Specifically, interviewees were asked if they ever felt the need to alter their communication to complement, emulate, or otherwise adjust to masculine communication styles. The majority of women interviewed reported having to strategically choose …
