Effects Of Environmental Stressors On Human Tissue-On-A-Chip Platforms, Andie Padilla

Open Access Theses & Dissertations

As space exploration begins to extend beyond low earth orbit, it has become increasingly critical to understand the interaction of the extreme environment of space flight with human systems. While it is known that space-travel induces a vast array of complications to cardiac, neural, musculoskeletal, and immune systems, the mechanisms by which these complications occur are poorly understood. Current research to study the effects of microgravity and radiation are limited to ground simulations, which rarely account for the multifactorial stressors experienced during spaceflight, or long duration studies aboard the International Space Station. Similarly, traditional two-dimensional (2D) models lack the ability …

Investigating Temporally Dynamic Models Of Choice In Rats And Bumblebees, Jack Van Allsburg

All Graduate Theses and Dissertations, Fall 2023 to Present

Temporally dynamic models of choice simulate how animals use past experience to make optimal decisions in variable environments. Chapter 1 briefly reviews a series of such modeling approaches and their mathematical properties. Extension of these models to longer experiments (more than 48 hours) designed to produce spontaneous recovery of choice (a behavioral phenomenon implicated in relapse) previously led to results not described well by current models. Chapter 2 comprises an empirical investigation of different explanations for these inconsistent results using rats, evaluating the effect of different test delays on preference following varied reward conditions. The results of the first two …

Gender-Diverse Individuals' Mathematics Self-Efficacy, Aliya Halterman

All Graduate Theses and Dissertations, Fall 2023 to Present

Many factors influence how well someone learns and achieve in school and daily living, with motivation being especially important. One key part of motivation is something called self-efficacy, which refers to how much someone believes they can successfully do a specific task (Bandura, 1986; 1997). Research has shown that self-efficacy plays a major role in how well people do, and the quality of their efforts (Pintrich & Schrauben, 1992; Weinstein & Mayer, 1986; Zimmermann, 2000). Additionally, mathematics skills are tied to better outcomes in school, careers, and in daily life. Mathematics also has also had a complex history when it …

Three Essays On Entrepreneurial Orientation And Competitive Repertoire, Gang Fan

Judicial And Techno-Securitization Of Immigration: Narratives De Filosofia De Inmigracion Y Justicia, Mohammad Rubaiyat Rahman

Open Access Theses & Dissertations

In the thesis, I develop a philosophical account which is centered on immigration enforcement discrimination, surveillance and procedural justice. The thesis propounds two arguments. The first argument contends that the immigration enforcement of the United States (U.S.), including the use of surveillance technology, contributes to the structural injustice. The second argument is that the U.S. immigration surveillance and immigration enforcement should be qualified by procedural justice and constitutional democracy.

The thesis prioritizes the practice of the U.S. immigration policy, enforcement and how these promote structural injustice against non-citizens and citizens, specifically those who are Latinos living in the U.S.-Mexico borderlands. …

Exercising Sovereignty In The Theater Of Court: How Performative Punishments Has Substitute Law Implementation In The Islamic Republic Of Iran, Nina Maziar

Graduate Theses and Dissertations

Abstract Legality is a modern infrastructure, but when it is combined with the jurisprudence, which is very interpretive and subjective, an amorphous content is merged, which can be shaped for utilitarian purposes; and this is how the arbitrary legal system of Islamic Republic is staged. This unshaped legal system, courts/trials and penal codes, especially political charges are ambiguous contents, baffling the mindsets. This unclear setting is deterministically vague to scare the victim, and the audience with the stagecraft of the court. Sovereignty is defined both in the international affairs regarding the capability of one state ruling a country, but it …
