Our results and findings are consistent with the literature.

Federalism By Deception: The Implied Limits On Congressional Power, Fair, Bryan K.

Santa Clara Law Review

The purpose of this Article is to lay bare federalism by deception and the theory of implied limits on federal power. Other scholars have recently noted the rise of anti-federalist viewpoints in modern cases. I go a step further to demonstrate how Supreme Court Justices have embraced anti-federal ideology, but have cited Federalist sources, including Marshall, to announce unenumerated limits on federal legislative power.

Somatechnics And Difference, Johannes Birringer

Teatro: Revista de Estudios Escénicos / A Journal of Theater Studies

This essay examines embodiment and technology with a special focus on dis/abilities in live performance during the current inter-pandemic era. After several workshops developed with performers and mixed ability artists during 2021, questions are raised about inclusion: how we consider impairment or how disabilities are reconfigured in our understanding. The somatechnics explored here are initially related to Seo Ji Won’s exuberant and excessive motion installation, but also to the practices of other choreographers and designers who acknowledge different abilities and challenges to perception that are not
necessarily all based in a technological understanding of movement. Although it can incorporate digital …

Covid-19 And Advanced Course Enrollment: Kentucky High Schools, Jessica Thomas

MPA/MPP/MPFM Capstone Projects

In Kentucky governments, districts, and schools made decisions about school closures and mode of learning that would impact community health as well as student achievement. Within those schools, students themselves were also making decisions that could impact their futures academically. In spring 2020, students were choosing their courses for the following year. Vast uncertainty about what the 2020/2021 school year would look like had the potential to impact those decisions. Disruptions to spring 2020 classes could also impact whether a student felt they had learned the prerequisite skills needed to pursue advanced coursework. This study found that advanced course enrollment …

These programs are designed to attract new residents to their area which in turn will have economic impacts …

The Effects Of "Sticky Stuff" On The Spin Rate And Break Of A Baseball Pitch, Natalie Dale

Scripps Senior Theses

In June 2021, Major League Baseball cracked down on the use of foreign substances by pitchers on the ball (Castrovince, 2021a). It is believed the sticky substances give the pitchers an unfair advantage over batters since they increase spin rate, consequently, through the Magnus Effect, creating more movement or “break” in the pitch, making it harder to hit. There are existing gaps in empirical research on this topic, thus the goal of this project was to determine the effect the banned substances have on the spin rate and related break of the pitches. By using pitch tracking technology, two types …

The Impact Of Self-Affirmation On Individuals’ Stress Levels And Performance - A Longitudinal Study, Tarana Jhunjhunwala

Scripps Senior Theses

Abstract

The self-affirmation theory postulates that when an individual is faced with a threat, they have an inherent motivation to affirm the positive beliefs they carry about themselves. (Steele, 1988). The use of these affirmations has been shown to be extremely effective in academic environments, boosting performance in students and also reducing their stress levels. However, there is very little research on the long-term effects of Self-affirmations on performance, and negligible research on its long-term effects on stress. This present study will aim to further understand the immediate effects as well as the longitudinal impact of these affirmations on individuals …

It's About Time: Emphasizing Temporal Dynamics In Dynamic Personality Regulation, Joshua Wilt

Faculty Scholarship

People change over time. These changes are thought to represent some self-regulatory, dynamic processes. However, dynamic processes need to be distinguished from mere stochastic variation. Just as the Brownian motion of a dust mote does not help us understand the basic principles of classical physics, neither does random variation within an individual describe the complexity of self-regulatory processes. This regulation implies solving the problem of competing goals and desires within the constraints of situational presses. And what people feel, think, and do at one moment affects what they feel, think and do in the next moment. Thus, describing and explaining …

Fertilizer Use In Aquaculture, Bartholomew W. Green

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Aquaculture ponds traditionally are fertilized to stimulate primary productivity, which serves as the base of the pond natural food web and provides ancillary ecosystem services. Fertilizer can be made regularly or based on some water quality variable or measure of algal productivity. Nutrients from chemical fertilizers are available sooner for phytoplankton growth compared to organic fertilizers that first must undergo microbial decomposition before nitrogen and phosphorus concentrations increase. Primary production increases with increased fertilizer application if productivity is limited by primary nutrients rather than by light. In semi-intensive and intensive production systems, natural pond productivity enhanced by targeted fertilization protocols …

Hybrid Quantum-Classical Unit Commitment, Reza Mahroo, Amin Kargarian

Faculty Publications

This paper proposes a hybrid quantum-classical algorithm to solve a fundamental power system problem called unit commitment (UC). The UC problem is decomposed into a quadratic subproblem, a quadratic unconstrained binary optimization (QUBO) subproblem, and an unconstrained quadratic subproblem. A classical optimization solver solves the first and third subproblems, while the QUBO subproblem is solved by a quantum algorithm called quantum approximate optimization algorithm (QAOA). The three subproblems are then coordinated iteratively using a three-block alternating direction method of multipliers algorithm. Using Qiskit on the IBM Q system as the simulation environment, simulation results demonstrate the validity of the proposed …
