Results indicated that both the elementary (SB-E) and middle school (SB-M) versions …


From Ads To Enrollment: Understanding How Targeted Marketing Affects College Choice, John W. Roberts Jan 2025

From Ads To Enrollment: Understanding How Targeted Marketing Affects College Choice, John W. Roberts

Theses and Dissertations--Educational Policy Studies and Evaluation

The purpose of this qualitative study is to explore the perceived impact of targeted marketing on college choice. Research on college choice is an established area of scholarship that explores the variables that are at work when a student chooses to attend a college or university. Given that the enrollment landscape for higher education continues to be competitive, colleges and universities are doing what they can to “stand out” among the competition in a crowded marketing and advertising space. And, as technology improves, segmenting and personalizing marketing to reach the right students at the right time is becoming more commonplace …

Investigation Of Subsurface Thermal Radiation Phenomena In Fibrous Thermal Protection Systems, Colby L. Gore Jan 2025

Investigation Of Subsurface Thermal Radiation Phenomena In Fibrous Thermal Protection Systems, Colby L. Gore

Theses and Dissertations--Science, Technology, Engineering, and Mathematics (STEM) Education

Atmospheric re-entry induces intense thermal stress upon vehicles through a high-enthalpy boundary layer that encompasses the craft. To protect these vehicles, numerous insulative methods, known as thermal protection systems (TPS), are deployed to protect the craft during re-entry. The TPS materials insulate the craft from intense thermal transmission that would terminate a mission. In hypersonic environments, vast temperature gradients exist, enforcing the exponential effect of thermal radiation. However, TPS materials are commonly low-density fibrous materials that allow for the potential to be penetrated by thermal radiation. A series of arc-jet tests was completed to replicate enhanced radiative conditions in a …

Making Headway On Sports Concussion: Sport-Specific Strategies For Concussion Prevention, Marcus Moore Jan 2025

Making Headway On Sports Concussion: Sport-Specific Strategies For Concussion Prevention, Marcus Moore

All Faculty Publications

Concussions in sports are a significant public health concern worldwide. Concussion is a traumatic brain injury (‘TBI’) resulting from biomechanical forces transmitted to the head that disrupt normal neurological function. Globally, an estimated 69 million TBIs occur annually. Concussive effects can persist as long-term syndromes (post-concussion syndrome), or compound themselves into life-threatening emergencies (second-impact syndrome). Chronic, even subconcussive, impacts can ultimately lead to degenerative neurological conditions (chronic traumatic encephalopathy). Troublingly, to date, there remains no medical cure for concussions. Prevention is thus paramount, as well as management, to avoid the compounding of injury or dangerous complications, as noted. Sports and …

Can Cystic Fibrosis Be Treated With Genetic Therapy?, Steve Silverberg Jan 2025

Can Cystic Fibrosis Be Treated With Genetic Therapy?, Steve Silverberg

The Science Journal of the Lander College of Arts and Sciences

This paper discusses the current and prospective treatment options for the fatal genetic disease cystic fibrosis. Cystic fibrosis (CF) is a rare recessive genetic disorder that is caused by a mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, which codes for a protein that is on the surface of a cell. This protein allows for the flow of chloride, bicarbonate, and sodium ions to pass through the cell wall, bringing water with it. When this protein doesn’t work, the lack of ions and water in extracellular fluid becomes too thick, causing a multitude of problems. The most common …

Despite technological innovation and the COVID-19 pandemic, there is a dearth of experimental research on the effects of virtual instruction. Using an original field experiment conducted among 100 UAE and USA students, we investigate how a Collaborative Online International Learning (COIL) project on international development shapes social trust, tolerance, and political engagement. In an experimental design, UAE-based students were randomly assigned to a group with either their classmates or, through online interaction, with USA-based students, while in a quasi-experimental design, USA-based students collaborated online with UAE-based students. UAE-based COIL students developed greater interpersonal trust of others in their society, but …


Will Malaysia Become An Active Middle Power?, Bruce Gilley Jan 2025

Will Malaysia Become An Active Middle Power?, Bruce Gilley

Politics and Global Affairs Faculty Publications and Presentations

Malaysia’s economic growth and democratisation since 2003 have vaulted it into the ranks of the middle powers in the international system. However, Malaysia remains hesitant about its middle power status. It has assumed a counterhegemonic or pro-multipolarity role; it has supported some new international rules and institutions; it leads regional governance institutions; and it advocates for small countries on development issues. However, these middle power behaviours are countered by a continuation of traditional Malaysia diplomacy which is inactive in shaping the emergence of superpower China as well as being disruptive and personalistic, most recently because of its embrace of radicalisms. …


Capital Structure And Business Failure: The Collapse Of Canada’S Dome Petroleum, Bruce Gilley Jan 2025

Capital Structure And Business Failure: The Collapse Of Canada’S Dome Petroleum, Bruce Gilley

Politics and Global Affairs Faculty Publications and Presentations

In popular lore, the failure of Canada’s once-biggest company, Dome Petroleum, was caused by the interventionist policies of the federal government or its misadventures drilling for oil in the Arctic. But these factors acted in varied ways on the company. Rather, corporate finance theories offer more insight into the dynamics that led to Dome’s takeover by the American oil major Amoco in 1988. Dome was unique in its unwillingness to issue new share capital during its growth phase and instead relied on easy debt financing. This in turn was a result of both insider preferences as well as capital market …

Rising From The Ashes: Reading Impacts And The Effects Of Recovery Educational Services Following A Major Natural Disaster, Tiffanie Lousia Lambert

Educational Leadership Professional Doctorate Dissertations

This Improvement Science Dissertation examined solutions to improving literacy outcomes for students in an elementary school that experienced a wildfire during the pandemic. School data revealed lagging reading growth among students displaced by the wildfire despite educational recovery efforts. A root cause analysis to understand students' limited reading recovery led to more global concerns about school-wide literacy programming and the limited use of evidence- based approaches. School-wide data revealed that fewer than 30% of students in the school met literacy benchmarks since the wildfire. Though the fires disproportionally impacted low-income neighborhoods with higher representation of English Learners and students receiving …

Policy Forum: Are Carbon Contracts For Difference Well Suited For Canada?, Wei Cui Jan 2025

Policy Forum: Are Carbon Contracts For Difference Well Suited For Canada?, Wei Cui

All Faculty Publications

At least up to the release of the federal 2024 budget, many Canadian politicians, climate policy think tanks, and industry groups promoted carbon contracts for difference (CCfD) to complement carbon pricing. This commentary urges caution against the broad adoption of CCfDs. The author begins by noting that the current designs of provincial output-based pricing systems (OBPS) are not consistent with the expectation of the systems delivering robust price signals. He argues that CCfDs depend on such price signals, and they are not a plausible policy for encouraging the emergence of such signals. The author then argues that it is hard …


Machine Learning Applications In Epigenomics And Its Association With Health And Disease, Trevor Doherty Jan 2025

Machine Learning Applications In Epigenomics And Its Association With Health And Disease, Trevor Doherty

Doctoral

Epigenetic modifications can lead to altered phenotypes without a change in the DNA sequence itself. Disrupted gene expression regulated by epigenetic processes can result in cancers, autoimmune diseases and various other maladies. Machine learning (ML) involves the use of algorithms and models which are trained to learn patterns in data, and has demonstrated remarkable success in solving diverse, complex challenges. Epigenomic studies, such as those that use DNA methylation (DNAm) data, increasingly make use of ML techniques to process extremely high dimensional data obtained from high throughput platforms e.g., DNAm arrays. These datasets suffer from the curse of dimensionality, increased …

Interactions And Applications Of Optical Angular Momentum In Magneto-Optical Material, Seth R. Nelson Jan 2025

Interactions And Applications Of Optical Angular Momentum In Magneto-Optical Material, Seth R. Nelson

Dissertations, Master's Theses and Master's Reports

This dissertation explores the interactions and applications of optical angular momentum within magneto-optical materials. Beginning with a theoretical and experimental analysis of multiple reflection and refraction phenomena within magneto-optical material. We derive and verify the dependence of refractive indices on optical spin angular momentum and magneto-optical magnetization, resulting in nonreciprocal elliptical and linear polarization beam splitting effects and wavevector discretization. We fabricate a magnetless slab waveguide isolator with minimal optical loss. Extending our study to optical orbital angular momentum, we introduce a perturbation to the electronic transition model in bismuth-substituted iron garnets. We demonstrate that this perturbation leads to nonreciprocal …
