Risk Perception And Response Among International Students Of The University Of Southern Mississippi, Elida Lopes Souza Rocha

Master's Theses

Given the exposure of university campuses to hazards, disaster mitigation is a critical element of higher education policy. Although U.S. higher education institutions are leaders in the global education market, emergency warning systems give little consideration to how international students perceive risk, prepare for hazards, or access warning technologies available to them. This poses several questions regarding the suitability of hazards mitigation practices and the welfare of international students.

This thesis investigates the relationship between USM international students and natural hazards. Responses from online surveys and semi-structured interviews data were analyzed through qualitative and quantitative methods to document the extent …

Effects Of Nitrogen Management And Cultivar On Strawberry Production Under Disease Pressure, Kamille A. Garcia-Brucher

Master's Theses

Effects of nitrogen management and cultivar on strawberry production under disease pressure

Kamille Garcia-Brucher

California strawberry growers face increasing regulatory pressures to manage nitrogen (N) applications in their production system. Standard practice in the California strawberry industry is to apply a synthetic pre-plant controlled release fertilizer (CRF) to ensure the crop has sufficient N during winter establishment. Some research from the UC Cooperative Extension suggests this practice is not efficient at delivering N to the crop since most of the N is released from CRF before strawberry crop N uptake is significant. Another concern for California strawberry growers is loss …

Classifying Electrocardiogram With Machine Learning Techniques, Hillal Jarrar

Master's Theses

Classifying the electrocardiogram is of clinical importance because classification can be used to diagnose patients with cardiac arrhythmias. Many industries utilize machine learning techniques that consist of feature extraction methods followed by Naive- Bayesian classification in order to detect faults within machinery. Machine learning techniques that analyze vibrational machine data in a mechanical application may be used to analyze electrical data in a physiological application. Three of the most common feature extraction methods used to prepare machine vibration data for Naive-Bayesian classification are the Fourier transform, the Hilbert transform, and the Wavelet Packet transform. Each machine learning technique consists of …

On The Mobility Of Small Aperture Telescopes For Initial Orbit Determination And Apparent Magnitude Derivation Of Low Earth Satellites, Jonathan Ian Hernandez

Master's Theses

Maintaining Space Domain Awareness (SDA) of satellites in low Earth orbit (LEO) requires effective methods of tracking and characterization. Optical measurements of these objects are generally sparse due to limited access intervals and high angular rates. Light pollution and geographic obstructions may also preclude consistent observations. However, a mobile small aperture telescope grants the ability to minimize such environmental effects, thereby increasing capture likelihoods for objects within this regime. By enhancing LEO satellite visibility in this way, extensive orbital and visual data are obtainable.

An 8-inch Meade LX200GPS telescope equipped with a Lumenera SKYnyx2-0M CCD camera comprises the system that …

Characterizing Direction Specific Ganglion Cell Receptor Activation Using A Perturbation Based Decomposition Method, Camila Paola Monchini Moline

Master's Theses

Characterizing postsynaptic current signals in the retina by neuroreceptor activation frequency is important for studying the mechanism of action behind phototransduction of varied visual stimuli. A better understanding could in turn lead to the creation of methods for early detection and prevention of debilitating optical neuropathies, such as glaucoma, age-related macular degeneration, and retinitis pigmentosa. More recent in-vitro and in-vivo studies have aimed to differentiate the effects of various neurotransmitters, such as acetylcholine, GABA, and glutamate, on receiving and processing different types of visual stimuli from the retina into the visual cortex.

The focus of this work will be to …

Indoor Positioning Using Synchronized Ultrasonic Ofdma Signals, Julian Bartolone

Master's Theses

This paper proposes a method of short-range indoor localization using differential phase measurements of synchronized two-tone ultrasonic signals in an Orthogonal Frequency Multiple Access (OFDMA) scheme. This indoor positioning system (IPS) operates at an ultrasonic frequency of approximately 40kHz and synchronizes using an infrared signal. The OFDMA scheme allows for a receiver to process the signals from multiple transmitters continuously without the signals interfering with each other. The phases of the signals are measured using Goertzel Filters, allowing for low-complexity frequency content analysis. A MATLAB simulation using the proposed localization method is performed using four transmitter nodes in the corners …

Get Into It: Unpacking The Relationship Between Hegemonic Norms And The Race And Gender Of Pop Artists, Bailey Shelton

Master's Theses

Many contemporary popular musical artists are victims of media controversy while they simultaneously make musical chat history. As a culture founded and sustained by a white supremacist capitalistic patriarchy, race and sex appear to influence the way hegemonic in-groups treat minorities and the way minorities are perceived and live within the confines of said hegemony. With the context of understanding feminist theories, hegemonic norms, parasocial relationships, celebrity appeal, and norms, the researcher wanted to understand if there are clear relationship among these frameworks in modern society. This study employed a 2x2 2between subjects factorial design method to gather information about …

Media Frames And Abortion Issue Polarization, Shianne Galuska

Master's Theses

The abortion issue is one of the most polarizing topics within the public and media sphere. How the media chooses to frame the abortion debate may influence public opinion and individual reactions. Specifically, articles that use incongruent abortion frames (pro-life/pro-abortion & anti-abortion/pro-choice) may be contributing to an ingroup versus outgroup mentality by highlighting who is the ingroup and who is the outgroup, thus generating moral disgust and polarization (characterized by anger, bias, and activism) amongst those with opposing views. This study sought to answer whether presenting individuals with an incongruent abortion frame increases anger, bias, and activism (polarization), as well …

Higher Command: An Examination Of African American Leadership In The Vietnam Era, Amanda Abulawi

Master's Theses

Since the founding of the United States, African Americans have sacrificed their lives to uphold the nation’s democratic ideals, all while being denied equal access to voting, education, employment, and housing rights at home. Military service appealed to many African Americans who hoped it would lead to social and economic advancement for themselves and their race. Despite African American military participation throughout the nation’s history, these soldiers were treated as outsiders through segregated units and often relegated to non-combative duties, until the Vietnam War. This was the first major conflict in which African Americans had been deployed in large numbers …

The Role Of Notch1 And Notch3 In Adult Stem Cell Osteogenic Differentiation, John Bradley Cart

Master's Theses

Human adipose-derived stem cells (hASCs) have significant therapeutic potential due to their ability to self-renew, differentiate down multiple lineages, and modulate the immune system. In addition to these many benefits, hASCs boast a minimally invasive harvesting procedure, making them a readily available cell source for stem cell research and tissue regeneration (Ock, et al. 2016) (Abdi, et al. 2008). Despite their broad use, very little is known about the mechanisms that control cell fate.


One way to enhance our mechanistic understanding of differentiation is through the systematic examination of the signaling pathways. The Notch signaling pathway is a highly conserved, …

Master's Theses

In this paper, we present how to use Hidden Markov Models (HMM) to predict the change in Unemployment Rate. By observing the NASDAQ price difference, we will predict the Unemployment Rate will rise or fall in the next month using the Hidden Markov Model. We will use the NASDAQ price and the unemployment rate from 2016 to 2020 monthly data for this paper. When we check the relation between the NASDAQ price and the unemployment rate, we find out that whenever the NASDAQ price goes up, the unemployment rate will drop for a time. So we are interested in how …

Snr: Software Library For Introductory Robotics, Spencer F. Shaw

Master's Theses

This thesis introduces "SNR," a Python library for programming robotic systems in the context of introductory robotics courses. Greater demand for roboticists has pressured educational institutions to expand robotics curricula. Students are now more likely to take robotics courses earlier and with less prior programming experience. Students may be attempting to simultaneously learn a systems programming language, a library API, and robotics concepts. SNR is written purely in Python to present familiar semantics, eliminating one of these learning curves. Industry standard robotics libraries such as ROS often require additional build tools and configuration languages. Students in introductory courses frequently lack …

Demographic Predictors Of Math Anxiety In Elementary School Children, Melissa Flowerdew

Master's Theses

Due to the increasing interest of math anxiety in elementary level children, the present study explored math anxiety contextual factors through Bandura’s (1999) Social Cognitive perspective. Using the Children’s Anxiety in Math Scale, researchers gathered data from 40 primary-level children to explore four demographic predictors--grade-level, special needs identification, gender identity, and socioeconomic status-- of mathematics anxiety through a hierarchical regression model. Findings indicated demographic variables accounted for over one-third of the variance in math anxiety scores at 38.2% (grade level: 12.3%, SNI: 8.4%, gender identity: 13.2%, SES: 4.1%). With the exception of socioeconomic status, all predictors were significant. These findings …

The Inclusion Of Vocal Health In The School Curriculum: A National Survey Of School-Based Speech-Language Pathologists And Speech-Language Pathology Assistants, Kate Mathews

Master's Theses

The human voice is an important tool of expression and a defining quality of self. Additionally, many occupations require, at least in part, a functioning voice for job completion (Titze et al., 1997). It is not surprising, then, that a dysfunctional voice may be disruptive and have a negative impact on a person’s quality of life. Unfortunately, disorders of voice are common, and perhaps even more so than many may realize (Bhattacharyya, 2014; Hartley et al., 2016; Roy, 2003; Roy et al., 2005). Several voice disorders, however, are preventable through the very same vocal health education means used in voice …
