An Investigation Of The Effectiveness Of Student’S T-Test Under Heterogeneity Of Variance, Hayden Nelson

Masters Theses & Specialist Projects

Within the field of psychology, few tests have been as thoroughly investigated as Student’s t-test. One area of criticism is the use of the test when the assumption for heterogeneity of variance between two samples is violated, such as when sample sizes and observed sample variances are unequal. The current study proposes a Monte Carlo analysis to observe a broad range of conditions in efforts to identify the resulting fluctuations in the proportion obtained significant results for two conditions: no mean difference (𝜇􀬵 = 𝜇􀬶) compared to the set level of alpha, and small-to-moderate mean differences (𝜇􀬵 ≠ 𝜇􀬶) compared …

Development Of An Enhanced Sampling Workflow To Accelerate Molecular Docking With Sparse Biophysical Information, Zachary Stichter

Masters Theses & Specialist Projects

Rapid docking of flexible biological macromolecules remains a significant open challenge in protein structure determination. While rigid docking is relatively simple with toolkits such as TagDock, a key obstacle to rapid flexible docking is the complexity and roughness of the free energy surface associated with protein conformational motion (often termed the many-minima problem), meaning conventional molecular dynamics methods do not effectively sample protein conformations near the interaction complex in accessible timescales. Methods such as metadynamics and replica exchange molecular dynamics exist to ameliorate this obstacle, yet these methods use nonphysical biases or random swaps to enhance sampling. In contrast, high …

Meaning In Life And Metacognition: Application Of The Self-Validation Hypothesis, Liam Hill

Masters Theses & Specialist Projects

Meaning in Life is a robust predictor of various positive outcomes, and provides a buffer against a host of negative outcomes. Due to this fact, it becomes important to examine all the facets of a meaningful life. One consistent predictor of Meaning in Life (MIL) in the literature is one’s sense of positive affect. I tested the idea that it is possible to doubt (or have confidence in) one’s affect, such that under conditions of doubt, positive affect is less strongly related to MIL. It may be the case that positive affect predicts MIL because of what we think of …

Cannabidiol (Cbd) And Resistance Training: Does Cbd Attenuate Acute Pain?, Guillermo Pacheco

Masters Theses & Specialist Projects

INTRODUCTION: Resistance training (RT) is an advantageous form of physical activity for health and performance benefits; these benefits are maximized when done strenuously. However, strenuous RT can induce acute inflammatory pain which can lead to delayed-onset muscle soreness (DOMS). Common analgesics like non-steroidal anti-inflammatory drugs (NSAIDs) can block protein synthesis, so other alternatives are needed for exercise and athletic communities to maintain physiological adaptations. Cannabidiol (CBD) is a non-psychotropic cannabinoid with purported anti-inflammatory, anti-oxidative, and analgesic properties. One of the main reasons for the use of CBD in exercise is pain alleviation; however, research in humans is limited. Therefore, the …
