The Effects Of Different Types Of Virtual Reality Display On Perception Of A Virtual Presenter, Ferran Poage

Honors Theses

Virtual reality (VR) displays present an immersive 3D virtual world that convey a sense of presence. These displays are rapidly increasing in fidelity, from traditional 2d desk monitors to head-mounted displays (HMD’s) like the Oculus Rift. Research must investigate the relationship between this growing level of fidelity in displays and the virtual experiences they produce, especially as high-fidelity devices become more widespread. Evidence shows that the fidelity of VR displays can affect a variety of factors such as spatial awareness, communication, engagement, arousal, enjoyment, and presence. The current study investigated the potential relationship between the fidelity of VR displays and …

The Presence Of Photoreceptor Sensilla In The Posterior Sucker Of Medicinal Leeches Inferred Through Functional Visual Response., Claire Spivey

Honors Theses

Medicinal leeches gather visual input from both its eyecups and photoreceptors across its body surface; each of its 21 midbody segments possesses 14 photoreceptive sensilla. It has been previously established that the posterior sucker is composed of seven body segments that are fused during embryogenesis. Similarly, four body segments fuse to create the anterior brain. There are five bilateral pairs of eyes located on the dorsal surface of the leech’s head and seven bilateral pairs of sensilla distributed over the surface of each midbody segment (Kretz et al., 1975). If no sensilla were lost during the fusion of the seven …

Thermal Adaptation Of A Vacuum Chamber, Jacob Russell

Honors Theses

The process of adapting a preexisting vacuum chamber to perform thermal vacuum testing is a rare process in the testing industry. A closed vacuum system that was designed without thermal capacitance in mind will hinder the development of additional thermal system capabilities and prove difficult from a cost standpoint. Generally, building a thermal vacuum system from scratch will cost on the order of $10,000 to $100,000 depending on the system requirements regarding control and thermal capacitance within the chamber. This project will explore the cost of such an adaptation, attempting to minimize expense, and potentially provide the “Western Aerospace Launch …

Comparing Prompting Methods For Teaching Receptive Identification, Laurel Jungblut

Honors Theses

Receptive language is the occurrence of an appropriate response to the spoken language of another individual. This is a key element of development, especially in regard to the acquisition of spoken language (Grow & LeBlanc, 2013). While this appropriate responding is a skill generally acquired by typically developing children via interactions with their caregivers, in most situations it must be explicitly taught to children with developmental delays (Charlotte L. Carp, Sean P. Peterson, Amber J. Arkel, & Anna I. Petursdottir, 2012). An absence or delay of this skill will result in a child missing many important learning opportunities, leading to …

Increasing The Frequency Of Tutors' Reinforcement Of Compliance Behaviors, Sruthi Rameshkumar

Honors Theses

Abstract

Compliance behaviors occurring prior to the delivery of an instruction, such as handing over preferred items, making eye contact, and folding hands in the ready position help prepare students for success in discrete-trial training (DTT) interventions. These behaviors are usually taught in early intervention with a continuous reinforcement schedule, but once they are mastered, they are rarely revisited or maintained. Without intermittent reinforcement of these behaviors, they are likely to decrease in frequency and may lead to the use of restrictive or intrusive methods to gain compliance during DTT sessions. The current study used a multiple-baseline across participants design …

Screaming, Humming: A Look Into Student Theatrical Direction And The Importance Of Queer Narratives On Stage And In The Rehearsal Room, Kropveld Danielle

Honors Theses

There is a large lack of discussion and writing concerning the intersections of queer theory, theatre as an art form, and student direction. My thesis attempts to add to this small amount of work. Using historical evidence, I define radical queer theory and its implications for art. I contextualize my own work in the rehearsal room with the piece Screaming, Humming by Hannah Manikowski with this framework, and speak to my experience of casting and rehearsal.

As a student director whose acting collaborators are also students, there are additional considerations to be taken into account. This experience also serves as …

Internalizing Disorders Among Mississippi Public School Students And The Need For Intervention, Madison Varner

Honors Theses

Childhood anxiety disorders traditionally do not garner much attention in academic settings. However, many studies have concluded that approximately 1 in 8 children has an anxiety disorder by age 12, often beginning at earlier ages but going undiagnosed. Further, studies have shown that these disorders strongly affect both behavior (e.g. bullying, school attendance, and social performance) and academic performance (e.g. literacy, mathematical learning). Under several existing pieces of legislature, public schools should already be providing treatment for these disorders; however, due to financial costs and the silent nature of these internalizing disorders, few schools have any provisions for the numerous …

Determining The Depositional Environment Of Amherstburg Formation, Elizabeth Gaines

Honors Theses

The Amherstburg Formation is a unit that stretches from Ontario to Michigan and was deposited during the Devonian Period. The goal of this project was to determine the depositional environment of the Amherstburg Formation. Facies associations were defined based on observations from three cores in northern and southeastern Michigan and later grouped into facies associations. The four facies associations were reef rubble, lagoonal, lagoonal and reef-rubble, and lagoonal and peritidal environments. These environments were deposited as laterally adjacent environments along a ramp shelf in a humid tropical climate. Sea level was relatively high during the deposition of the Amherstburg Formation. …

Exploring And Improving The Uses Of Near-Term Quantum Annealers, Nic Ezzell

Honors Theses

Quantum annealing (QA) is a global search-heuristic designed to solve NP-hard optimization problems. Currently, D-Wave Systems is the only commercial QA company, boasting a line of chips that have over 2000 working qubits. Unfortunately, their API lacks many useful features for exploring the actual physics and efficacy of QA as an optimization tool. Further, the typical QA routine is prone to errors for a variety of reasons: noise, problem mis-specification, minor-embedding errors, and using incorrect annealing parameters. This work attempts to alleviate both of these issues with a single Python package: dwaveutils. With it, we explore two case studies: simulations …

Design And Synthesis Of A Novel Lsoxazoline As A Potential Pam-Agonist, Josselyn Roosenberg

Honors Theses

Progression of Alzheimer's disease is associated with a loss of Ml receptor activation in the brain. However, a lack of clinical success following attempts to activate the Ml receptor at the orthosteric site has contributed to a transition towards the allosteric pocket of the receptor. Here, positive allosteric modulators (PAMs) interact to potentiate the acetylcholine response. Recent research proposes that optimization of PAM activity at the expense of intrinsic agonism may posit a means to limit adverse side effects. Therefore, this project proposes a design and synthesis of a novel isoxazoline as a potent PAM agent with weak intrinsic agonism.
