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 …

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 …

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 …

Fire Emissions In The Tropical Indonesia: Improved Estimation And Driving Forces Investigation, Xiaoman Lu Jan 2022

Fire Emissions In The Tropical Indonesia: Improved Estimation And Driving Forces Investigation, Xiaoman Lu

Electronic Theses and Dissertations

Indonesia has experienced frequent fires since the 1970s due to large-scale peatland conversion and extensive drainage for agricultural development. Fire emissions released from these fires have led to Indonesia being the world’s 3rd largest emitter of greenhouse gases in certain years. Given that fire emissions severely affect climate, weather, and the human environment, numerous approaches have been developed to estimate fire emissions. However, existing emission estimates differ largely by a factor of four in this tropical country because of frequent cloud interferences and low-temperature smoldering fires. Therefore, this dissertation aims to improve the quantification of Indonesian fire emissions through enhanced …

Newcomer Adjustment And Affective Commitment: A Two-Wave Moderated Mediation Model, Shay Norris Jan 2022

Newcomer Adjustment And Affective Commitment: A Two-Wave Moderated Mediation Model, Shay Norris

Electronic Theses and Dissertations

As job and career changes continue to increase in the post-pandemic work environment, new employees are not staying in their roles long enough to identify with their organization, causing high turnover in the first few months of employment. To address these problems, there is increasing evidence that providing resources and support during the socialization process will increase employee commitment, retention, and organizational performance. I propose that an integrated theoretical framework combining Socialization Resources Theory (SRT) and Job Demands-Resources Theory (JD-R) is best suited to explain the relationship between newcomer adjustment and affective commitment. A moderated-mediation model is developed and tested …

The Impact Of Facebook Affordances On Doomscrolling Behaviors During The Relational Dissolution Process, Emma Williams Jan 2022

The Impact Of Facebook Affordances On Doomscrolling Behaviors During The Relational Dissolution Process, Emma Williams

Electronic Theses and Dissertations

The affordances provided by social networking sites (SNSs) impact how different social media platforms are used. Facebook has unique affordances such as ease of use, community, information seeking, escapism, and common interests that impact Facebook use. Interpersonal electronic surveillance, categorized as doomscrolling for this study, is a behavior of continuous scrolling and consumption of negative content. Facebook affordances, paired with digital artifacts from terminated relationships, create an environment for doomscrolling (IES) behavior. Building off of the “grave-dressing” and “resurrection” stages of relational dissolution, I examined the relationships of these Facebook affordances with doomscrolling (IES) behaviors through an online survey (N …
