Extended Cross-Referenced Analysis Using Data From The Landsat 8 And 9 Underfly Event, Garrison Gross Jan 2023

Extended Cross-Referenced Analysis Using Data From The Landsat 8 And 9 Underfly Event, Garrison Gross

Electronic Theses and Dissertations

The Landsat 8 and 9 Underfly Event occurred in November 2021, where Landsat 9 flew beneath Landsat 8 in the final stages before settling in its final orbiting path. An analysis was performed on the images taken during this event, which resulted in a cross-referenced with uncertainties estimated to be less than 0.5%. This level of precision was due in part to the near-identical sensors aboard each instrument as well as the underfly event itself, which allowed the sensors to take nearly the exact same image at nearly the exact same time. This initial calibration was applied before the end …

The Role Of Carbon Credits On Farmers’ Adoption Of Climate-Smart Practices In South Dakota, Stephen Cheye Jan 2023

The Role Of Carbon Credits On Farmers’ Adoption Of Climate-Smart Practices In South Dakota, Stephen Cheye

Electronic Theses and Dissertations

Net-zero pledges and carbon credit systems have gained momentum due to the growing urgency to address climate change and limit global warming to below 2°C above preindustrial levels. Agricultural carbon credits can be a potentially win-win mechanism by providing extra income for farmers while helping to reduce greenhouse gas emissions. Nevertheless, there is a paucity of understanding about farmers’ willingness to accept carbon credit incentives and adopt climate-smart practices that sequester carbon. To address this, we analyzed 309 responses from a South Dakota producer survey conducted in 2021. We estimated probit and interval regression models to ascertain the level of …

Theoretical Motivations For Posting In #Metoo, Shannon Pappas

Electronic Theses and Dissertations

In 2017, actress Alyssa Milano shared a tweet encouraging survivors of gendered violence to write “me too.” A media storm ensued as survivors answered her call in the millions. Anyone can look back at what survivors posted during the height of #MeToo, but we still don’t know why they felt the need to post in the first place. To answer this question, the social identity model of deindividuation effects and spiral of silence were utilized. The social identification, perceived anonymity affordances, and willingness to self-censor scales were used for this research, along with a perceived deindividuation scale that was created …

Firm-Level Political Risk And Corporate R&D Investment, Emmanuel Boah Jan 2023

Firm-Level Political Risk And Corporate R&D Investment, Emmanuel Boah

Electronic Theses and Dissertations

I examine how firms make R&D investment decisions during periods of political uncertainty. To minimize stickiness and overly generalized assumptions, I employ quarterly data. I find that firms invest more in R&D when facing high levels of political risk. The results suggest that this positive relationship between political risk and R&D investment is more pronounced for competitive and politically sensitive firms. Additionally, the positive association is evident among firms with higher growth opportunities and more liquid assets. The results are robust to the test for correlation, addressing endogeneity, and alternative proxies adopted for the variables of interest. Overall, the findings …

Would Ai Stocks Estimate Be As Surprised To Usda Stocks Reports As Private Market Analysts?, Asif Mahmud Chowdhury

Electronic Theses and Dissertations

The USDA survey-based Quarterly Agriculture Stocks (QAS) reports are the primary source of information regarding the relative supply of U.S. corn, soybeans, and wheat for the last fifty years. Research has examined USDA stock reports and their relevancy to the market (e.g., Isengildina-Massa et al., 2021). In addition, private industry analysts estimate expected quarterly grain stock reports before USDA releases them. Market information firms such as Bloomberg and Reuters publish a subset of these estimates a few days before the USDA reports. Previous research has found that when industry analysts have significant differences in stock expectations compared to what the …

Fighting For What Is Right: A Rhetorical Analysis Of The Fan Campaign To Save Anne With An E From Cancellation, Marie E. Anderson Jan 2023

Fighting For What Is Right: A Rhetorical Analysis Of The Fan Campaign To Save Anne With An E From Cancellation, Marie E. Anderson

Electronic Theses and Dissertations

The Anne with an E fan campaign highlighted storylines of social issues that fans felt were important for society. Of particular interest to the fan community was a storyline from the series in which Anne and her friends organized a protest following incidents of sexual assault and censorship aimed at silencing girls from speaking out on gendered issues. This storyline was heavily referenced in the billboards that the fan-based campaign displayed in Toronto and New York City (Anne Nation, 2020). In this analysis, I used fantasy theme analysis (Bormann, 1972) and metaphorical criticism (Osborn, 2018) to conduct a visual and …

The Impact Of Cluster Strength On Wages: An Empirical Analysis, Devan Schaefer Jan 2023

The Impact Of Cluster Strength On Wages: An Empirical Analysis, Devan Schaefer

Electronic Theses and Dissertations

In this thesis, I examine the relationship between clusters (i.e., the grouping of competitive, interconnected industries within a geographical area) and wages, building upon the work of Marshall (1890) and Porter (2003) on the importance of clusters for regional economic development. I seek to answer two research questions. First, after accounting for robustness tests, do clusters continue to affect wages positively? Second, is labor force productivity the only channel through which this relationship occurs? In my analysis, I employ ordinary least squares, two-stage least squares, and fixed effects regression analyses using panel data from 2009 to 2014 for every U.S. …

Adaptive Learning Gain In Asset Pricing, Sedealy Juste Lokossou Jan 2023

Adaptive Learning Gain In Asset Pricing, Sedealy Juste Lokossou

Electronic Theses and Dissertations

This paper delves into the complexities of asset pricing, emphasizing the need to go beyond prevailing paradigms and constant learning gain assumptions. We examine the influence of personal experiences, adaptive learning processes, and subjective return expectations on asset pricing. By incorporating the concept of time-varying learning gain, we provide a more realistic portrayal of asset pricing. Empirical analysis reveals a consistent negative correlation between experienced real payout growth and subsequent returns, indicating counter-cyclical behavior. Our findings also support the mean-reversion hypothesis in stock returns, although caution is needed due to some scenarios lacking statistical significance. Theoretical exploration uncovers that higher …
