Shifting Sources Of Humanitarian Aid: The Importance Of Network Resiliency And Donor Diversification, Mackenzie Marie Clark

Graduate Program in International Studies Theses & Dissertations

As instances of forced displacement arise and become increasingly large and prolonged around the world, large influxes of humanitarian aid have become critical in assisting host countries with crisis response. The funding required to meet the immediate, emergency needs presented by a refugee situation is filled primarily by governmental humanitarian contributions, and more specifically, by the United States. Typically, the U.S. is integral to the structure of the networks of humanitarian aid being directed towards a humanitarian response as it is the largest donor, in most cases. However, what does this reliance on U.S. funding mean for the structural integrity …

Enhanced Traffic Incident Analysis With Advanced Machine Learning Algorithms, Zhenyu Wang

Computational Modeling & Simulation Engineering Theses & Dissertations

Traffic incident analysis is a crucial task in traffic management centers (TMCs) that typically manage many highways with limited staff and resources. An effective automatic incident analysis approach that can report abnormal events timely and accurately will benefit TMCs in optimizing the use of limited incident response and management resources. During the past decades, significant efforts have been made by researchers towards the development of data-driven approaches for incident analysis. Nevertheless, many developed approaches have shown limited success in the field. This is largely attributed to the long detection time (i.e., waiting for overwhelmed upstream detection stations; meanwhile, downstream stations …

Investigating The Disorder And Compaction Of Designed Minielastin Using Nuclear Magnetic Resonance., Ma Faye Charmagne Aquino Carvajal

Electronic Theses and Dissertations

Minielastins are elastin-based proteins with alternating hydrophobic and cross-link modules similar to tropoelastin. Tropoelastin is the ~70 kDa soluble monomeric precursor of elastin. The extracellular matrix protein, elastin provides elasticity to tissues and organs such as lungs, arteries and ligaments. The elastic properties of natural elastin are believed to be entropic in origin. In vivo, the elastin matrix is approximately 50% water by weight. Without water, elastin is brittle and hard. Minielastins, like tropoelastin, undergo a liquid-liquid phase transition upon an increase in temperature. Factors such as hydrophobicity, chain length and concentration affect the coacervation temperature, T_c. The …

Social Media And Fear: Social Media As A Catalyst For Political Fear In The United States., Shane R. White

Electronic Theses and Dissertations

Abstract: Using the American National Election Study data from the 2012 and 2016 surveys I explore how social media usage shapes fear. This is likely caused by the nature of social media leading to oversharing of sensationalized articles likely to elicit an emotional and fearful response. My findings suggest first that social media usage has a statistically significant effect on whether they would say they are afraid of a candidate (2012) and how afraid they say they are of the candidates (2016). Second, social media has little effect on economic fear, and may actually make people more hopeful about the …

The Ball Is In Your Court: A Phenomenological Study Examining College Athletes With Learning Disabilities And/Or Adhd On College Campuses., Stephanie Thea O'Donnell

Electronic Theses and Dissertations

Approximately only 1% of scholarly top-tier higher education published research focuses on the experiences of students with disabilities since the passing of the ADA in 1990 (Pena, 2014).

External Homophobia And Outness In Gay Men., Thomas Charles Isaak Jr

Electronic Theses and Dissertations

Prior studies regarding outness among gay men have often focused on internalized homophobia as a barrier to coming out for gay men, while less emphasis has been placed on external homophobia. Drawing upon social construction theory and Connell’s hierarchy of masculinity, I utilize data from the 2010 Social Justice Sexuality Project to complete an ordinary least square regression to examine the impact of external homophobia on the level of outness among the 987 gay men in this study. In this study, I find that gay men who were exposed to external homophobia reported decreased levels of outness. Further, I find …

Computational Behavioral Analytics: Estimating Psychological Traits In Foreign Languages., Kristopher Wayne Reese

Electronic Theses and Dissertations

The rise of technology proliferating into the workplace has increased the threat of loss of intellectual property, classified, and proprietary information for companies, governments, and academics. This can cause economic damage to the creators of new IP, companies, and whole economies. This technology proliferation has also assisted terror groups and lone wolf actors in pushing their message to a larger audience or finding similar tribal groups that share common, sometimes flawed, beliefs across various social media platforms. These types of challenges have created numerous studies in psycholinguistics, as well as commercial tools, that look to assist in identifying potential threats …

In Need Of A Hero? The Creation And Use Of The Legend Of General George S. Patton, Jr., Nathan Curtis Jones

Electronic Theses and Dissertations

During WWII, General George Patton became the hero Americans needed through the creation of a self-crafted brand and with help from journalists. After Patton’s death, opportunists forwarded a legend narrative that developed into a collective memory that morphed over time to meet contemporary challenges. Stakeholders of that collective memory commemorated and memorialized the dead hero for monetary and political gain, to promote patriotism, make military doctrinal changes, and even promote peace. Today, this collective memory has potential for the U.S. Army as it transforms civilians into soldiers and officers. This study contributes to history and memory studies by linking representations …

Persort Facilitates Characterization And Elimination Of Persister Subpopulation In Mycobacteria., Vivek Srinivas, Mario L Arrieta-Ortiz, Amardeep Kaur, Eliza Jr Peterson, Nitin Baliga

Articles, Abstracts, and Reports

Mycobacterium tuberculosis (MTB) generates phenotypic diversity to persist and survive the harsh conditions encountered during infection. MTB avoids immune effectors and antibacterial killing by entering into distinct physiological states. The surviving cells, persisters, are a major barrier to the timely and relapse-free treatment of tuberculosis (TB). We present for the first time, PerSort, a method to isolate and characterize persisters in the absence of antibiotic or other pressure. We demonstrate the value of PerSort to isolate translationally dormant cells that preexisted in small numbers within Mycobacterium species cultures growing under optimal conditions but that dramatically increased in proportion under stress …

Stability Analysis Of Krylov Subspace Spectral Methods For The 1-D Wave Equation In Inhomogeneous Media, Bailey Rester

Master's Theses

Krylov subspace spectral (KSS) methods are high-order accurate, explicit time-stepping methods for partial differential equations (PDEs) that also possess the stability characteristic of implicit methods. Unlike other time-stepping approaches, KSS methods compute each Fourier coefficient of the solution from an individualized approximation of the solution operator of the PDE. As a result, KSS methods scale effectively to higher spatial resolution. This thesis will present a stability analysis of a first-order KSS method applied to the wave equation in inhomogeneous media.

Biological Siblings: Can You Trust Them With Your Mate?, Elisha Barron

Electronic Theses, Projects, and Dissertations

Recent studies suggest that genes may influence human mate preferences. What would this mean for same-sex siblings who share genes? Might they also share mate preferences and engage in mate poaching or would social norms and strong sibling bonds discourage such behaviors? We hypothesized that siblings would perceive their mate preferences to be more similar to their sibling’s than to an average person of their same gender. It was also hypothesized that the association between perceived sibling mate preferences and sibling mate poaching would be moderated by sibling closeness and sibling competition. Additionally, it was hypothesized that sibling mate competition …

Demographic Differences In The Perceived Invasion Of Privacy When Social Media Is Used In Personnel Selection, Zayna Osborne

Electronic Theses, Projects, and Dissertations

The use of social media in personnel selection is a growing phenomenon amongst many organizations (Roth et al., 2016). However, different social media types, both personal and professional, arise when organizations use personal social media in personnel selection. The information present on personal social media platforms is often not relevant to the applicant's job qualifications. An important issue that arises when personal social media is used is the applicant's perceived invasion of privacy. There is very little literature that examines any demographic differences in the perceived invasion of privacy when social media is used in personnel selection. Understanding if there …
