In advanced photonics, there is a growing interest in piezochromic luminescent materials that exhibit multicolor switching, driven by their potential applications in optical recording, memory, and sensors. Here, the piezochromic behavior of 2,4,6-triphenylpyrylium tetrachloroferrate (Py-FeCl₄) under high pressures from 0 to 9 GPa is reported. The observed multicolor changing properties of Py-FeCl₄ (yellow–orange–red–maroon–black) are found to be fully reversible upon decompression to ambient conditions. The mechanism of Py-FeCl₄ piezochromism is investigated via Raman, infrared, and UV–vis spectroscopy combined with powder X-ray Diffraction. The absence of structural phase transitions as well as the abrupt shifts of bandgap …

Priming Through Persuasion: Towards Secure Password Behavior, Rizu Paudel, Mahdi Nasrullah Al-Ameen

Computer Science Student Research

Users tend to create weak passwords even for the important accounts. The prior research shed light on user’s insecure password behavior, and why the interventions, including requirement specification (e.g., password composition policies) and feedback systems (e.g., password meters) fail in practice. To this end, we propose and evaluate the concept: priming-through-persuasion in the realm of secure password creation. In particular, we created visual designs, aimed at priming users about the repercussions of weak passwords before their password creation. We base our designs on two forms of persuasion methods: pathos and logos. Pathos appeals to people’s emotion in order to persuade …

Promoting Mental Health And Well-Being Among Undergraduate Nursing Students: A Practice Guideline, Armen Mailyan

DNP Projects

Poor mental health and well-being among undergraduate nursing students negatively affects social dynamics, communication, decision making, and stress management, thus compromising the quality of healthcare delivery and patient care outcomes. It is imperative that nursing programs support students to develop positive self-care, resilience, and mental health skills while in school to foster their well-being, enhance their academic success, and to promote high-quality, patient-centered care in their future practice. The purpose of this Doctor of Nurse Practice (DNP) project was to develop a mental health and well-being practice guideline with a comprehensive set of evidence-based interventions for academic nursing programs to …

Charge The Cockpit Or Die: An Anatomy Of Fear-Driven Political Rhetoric In American Conservatism, Daniel Hostetter

Senior Honors Theses

Subthreshold negative emotions have superseded conscious reason as the initial and strongest motivators of political behavior. Political neuroscience uses the concepts of negativity bias and terror management theory to explore why fear-driven rhetoric plays such an outsized role in determining human political actions. These mechanisms of human anthropology are explored by competing explanations from biblical and evolutionary scholars who attempt to understand their contribution to human vulnerabilities to fear. When these mechanisms are observed in fear-driven political rhetoric, three common characteristics emerge: exaggerated threat, tribal combat, and religious apocalypse, which provide a new framework for explaining how modern populist leaders …

"Who Wrote The Epistle, God Only Knows": A Statistical Authorial Analysis Of Hebrews In Comparison With Pauline And Lukan Literature, Benjamin J. Erickson

Senior Honors Theses

The authorship of Hebrews has been a point of contention for scholars for the past two millennia. While the epistle is traditionally attributed to Paul, many scholars assert that it carries thematic, structural, and stylistic differences from the remainder of his extant epistles; therefore, many other possible authors have been proposed. Of these, only Luke has other New Testament writings. Therefore, this project conducts a statistical comparison of Hebrews to the Pauline and Lukan corpora using stylometric authorial analysis methods. This analysis demonstrates that Hebrews is stylistically closer to Lukan literature than Pauline (but not to a significant degree), and …

Normrank Correlations For Testing Associations And For Use In Latent Variable Models, Daniel B. Wright

Educational Psychology, Leadership, and Higher Education Faculty Research

Pearson’s correlation is widely used to test for an association between two variables and also forms the basis of several multivariate statistical procedures including many latent variable models. Spearman’s p is a popular alternative. These procedures are compared with ranking the data and then applying the inverse normal transformation, or for short the normrank transformation. Using the normrank transformation was more powerful than Pearson’s and Spearman’s procedures when the distributions have less than normal kurtosis (platykurtic), when the distributions have greater than normal kurtosis (leptokurtic), and when the distribution is skewed. This is examined for testing if there is an …

Structural Homology Of Mite Profilins To Plant Profilins Is Not Indicative Of Allergic Cross-Reactivity, Andrea O'Malley, Sahana Sankaran, Avery Carriuolo, Kriti Khatri, Krzysztof Kowal, Maksymilian Chruszcz Ph.D.

Faculty Publications

Structural and allergenic characterization of mite profilins has not been previously pursued to a similar extent as plant profilins. Here, we describe structures of profilins originating from Tyrophagus putrescentiae (registered allergen Tyr p 36.0101) and Dermatophagoides pteronyssinus (here termed Der p profilin), which are the first structures of profilins from Arachnida. Additionally, the thermal stabilities of mite and plant profilins are compared, suggesting that the high number of cysteine residues in mite profilins may play a role in their increased stability. We also examine the cross-reactivity of plant and mite profilins as well as investigate the relevance of these profilins …

A Cold Laboratory Hyperspectral Imaging System To Map Grain Size And Ice Layer Distributions In Firn Cores, Ian E. Mcdowell, Kaitlin M. Keegan, S. Mckenzie Skiles, Christopher P. Donahue, Erich C. Osterberg, Robert L. Hawley, Hans-Peter Marshall

Geosciences Faculty Publications and Presentations

The Greenland and Antarctic ice sheets are covered in a layer of porous firn. Knowledge of firn structure improves our understanding of ice sheet mass balance, supra- and englacial hydrology, and ice core paleoclimate records. While macroscale firn properties, such as firn density, are relatively easy to measure in the field or lab, more intensive measurements of microstructural properties are necessary to reduce uncertainty in remote sensing observations of mass balance, model meltwater infiltration, and constrain ice age – gas age differences in ice cores. Additionally, as the duration and extent of surface melting increases, refreezing meltwater will greatly alter …

Spectral Properties Of Wetlands In Michigan Using Remote Sensing To Identify And Classify Wetlands In Roscommon County, Michigan, Kolin Williamson

USF Tampa Graduate Theses and Dissertations

Biological, geological, and physical. These are only a handful of the many environmental aspects that wetlands functions maintain and protect. Unfortunately, wetlands within the United States have been razed at an alarming rate. The State of Michigan has not gone through this unscathed either, loosing over 1000 acres of wetland a year. One of the most important tools to prevent this destruction are the maps and programs that show where these essential ecosystems are located. The current, federally-created maps and imaging software in use by environmental consultants and contractors may not be up to date which can pose challenges for …

“It’S Hard For Him To Make Choices Sometimes And He Needs Guidance”: Re-Orienting Parental Control For Children, Prakriti Dumaru, Hanieh Atashpanjeh, Mahdi Nasrullah Al-Ameen

Computer Science Student Research

With access to devices and online platforms at an increasingly younger age, it is essential to protect children from potential online risks. In our studies, we particularly focused the parents who have a child under 13 years of age. To this end, deriving from developmental psychology, we base our low-fidelity prototype design (termed as ‘treatment’) on a set of design principles focusing on open communication, instilling self-regulation, and availing granularity along with designs of existing Google’s parental control as a baseline. First, we conducted semi-structured interviews with 21 parents to understand their perceptions, including suggestions for design improvement within our …

Linking Reactive Nitrogen Species Within The Vadose Zone With Surface Irrigation, Kaitlyn Richards

Honors Program: Senior Projects (Public)

This study investigated the relationship between irrigation methods and the mobilization of nitrogen in the vadose zone, focusing on soil properties, water dynamics, and nitrogen species distribution. Data collected from dryland and pivot-irrigated soil cores reveal distinct patterns in water content, bulk density, soil texture, pH, conductivity, and nitrogen concentrations. Results indicated that water content has a major influence in nitrogen availability and microbial activity. Nitrate-N and ammonium-N concentrations varied between dryland and pivot soils, with notable disparities observed. In dryland soils, nitrate-N concentrations varied widely across depth intervals, with notable accumulation in deeper layers, while ammonium-N concentrations exhibited a …

Spectrophotometric Device For Early Malaria Detection, Adrian Wasylewski, Christopher Faber, Victor Lin

Honors Thesis

Malaria remains a significant global health challenge, with millions of cases reported annually, particularly in resource-limited regions. Timely and accurate diagnosis is crucial for effective treatment and disease management. Unfortunately, there are still significant challenges in existing testing procedures, which are often expensive, inaccurate, or impractical for mass testing. While spectrophotometry has been proposed as a detection tool for other tropical diseases such as dengue fever, no prototype has been made for any disease, including malaria. This report addresses this gap by presenting a spectrophotometric-based malaria detection tool that achieves high sensitivity at a low cost. The inclusion of a …

A Phenomenological Study Of The Teacher Leader Experience, Leslie Magnanti

Doctoral Dissertations and Projects

The purpose of this transcendental phenomenological study was to understand the lived experiences of teachers in leadership roles in a rural, secondary school setting. The theory guiding this study was the theory of distributed leadership created by Spillane and developed by Groff, as it explained the power of teacher leadership as a method of distributing leadership to promote teacher retention and motivation alleviating some principal stress and burnout. Data was collected using interviews of the ten participants to better understand how teachers experience leadership and how administrators can promote it, focus groups to understand the phenomenon in more depth, and …

The Relationship Between Participation In Chorus And The Acquisition Of Higher-Order Reasoning Skills Among Middle School Students, Jason M. Streun

Doctoral Dissertations and Projects

This predictive correlational study examined the relationship between participation in chorus and the acquisition of higher-order reasoning skills among middle school students. Although the education profession focuses on ways to engender higher-order reasoning skills in their students, today’s high-stakes climate so rigorously addresses STEM subjects that it tends to ostracize music from the discussion. Thus, the significance of this study lies partly in its endeavor to better understand the connection between linguistic development and reasoning, the positive influence that participation in choral music can potentially wield in the acquisition and improvement of linguistic skill, and, correspondingly, the attainment of higher-order …

Evolution In Complex Systems: A Computational Prespective, Andisheh Dadashi

Computer Science ETDs

As we are entering the era of multi-omic datasets, it is increasingly evident that the complexities of natural systems exceed the capabilities of current computational methodologies. My dissertation research aims to reduce this gap by using computational frameworks to investigate the evolution of complex systems. I apply a model of metabolic networks to predict human embryonic metabolism during peri-implantation (Chapter I), offering insights into the foundations of early human development. This dissertation further examines the basis of the phenotypic evolution of polygenic traits when subjected to directional (Chapter II) and temporally varying environmental shifts (Chapter III), revealing the roles of …

A Tale Of Two Toroidal Graphs, Akshat Gulgulia

Honors Theses

A graph is toroidal if it can be embedded on a torus which is a doughnut-shaped surface. Two well-known examples of toroidal graphs are the complete graph K5 and the complete bipartite graph K3,3. In this thesis we elucidate the association of the subject matter with two renowned enigmas in graph theory, namely the Five Princes Problem and the Three Utilities Problems. Additionally, we look at their association with several renowned theorems in topological graph theory. We explore the link between these two graphs and a contemporary labeling concept.

Numerical Investigation To Produce A Fundamental Polygon, Elizabeth Sipes

Honors College Theses

There exist multiple types of geometry, differing in the postulates they are based on, and therefore the theorems and proofs that make up said geometry. Hyperbolic geometry differs from others by allowing there to exist multiple lines through a single point not on a given line, that are parallel to the given line. Every geometry has the idea of distance and isometries, distance preserving maps. By considering special collections of isometries called discrete groups, we can construct interesting surfaces, such as the torus and genus-g surface. The connection between the surface and the discrete group can be understood through …

Measuring Soot In A Novel Configuration For Diffusion Flames Fueled By Ethylene Doped With Iso-Dodecane, Christian Bjork

Honors Scholar Theses

Sustainable Aviation Fuels (SAFs) are seen as the path forward for decarbonizing hard-to-electrify sectors. Using SAFs over traditional fossil fuels abates carbon dioxide emissions but still may present soot emission problems. A milestone in the abatement of soot would be understating its formation mechanisms.

This study aims to quantify soot products resulting from an ethylene flame doped with iso-dodecane, a surrogate SAF component. The burner selected for the investigation is the novel Planar Mixing Layer Flame (PMLF) which allows the tracking of soot formation with the height above the burner (HAB) in a stable diffusion flame. A baseline ethylene-fueled flame …

Quantum Lissajous Figures Via Projection, Errico Russo

Theses

We present and investigate a new category of quantum Lissajous states for a two-dimensional Harmonic Oscillator (2DHO) having commensurate angular frequencies. The states themselves result from the projection of ordinary coherent states (i.e. quasi-classical) onto a degenerate subspace of the 2DHO. In this way, new, highly non-classical quantum mechanically stationary states arise “organically” from the highly classical but non-stationary coherent states. The connection to Lissajous figures is evident in the result that our states so defined all have probability densities that are localized along the corresponding classical Lissajous figures. We further emphasize the important interplay between the probability current density …

Reimagining The Onboarding And Mentoring Needs Of California Community College Counseling Faculty: An Ecological Systems Approach Using Narrative Inquiry, Philip Lantz

LMU Theses and Dissertations

Despite California community college counseling faculty having unique roles on their campuses due to their faculty status and their proximity to students, there is a lack of research related to the experiences of counseling faculty and how they can be supported by local and statewide leaders to best meet the needs of the diverse student populations that are currently being served within the California community college system. This qualitative research study utilized narrative inquiry to examine the current onboarding and mentoring experiences of California community college counseling faculty to evaluate both best practices as well as institutional gaps that negatively …

Defining Best Practices And Validation For Curriculum Mapping, Hannah Smith, Jesse Chittams

College of Nursing Faculty Papers & Presentations

The alignment of curriculum content with standards is a quality improvement measure used to identify gaps or overlaps in academic content. Curriculum mapping results, while commonly used, are rarely reported. Undergraduate faculty mapped 11 courses in a single timepoint using a web-based curriculum mapping tool. Quantitative results were calculated and compared to defined client needs categories. A validation analysis was performed by mapping one course in triplicate. Faculty feedback following the exercise was obtained by online survey. Three client needs categories were determined to be marginally out of range in the initial analysis of the quantitative mapping data. The curriculum …

Investigating The Role Of Tryptophan In The Native Photo-Crosslinking Of A Cys-Containing Transmembrane Helix To A Membrane Lipid Double Bond, Michael Jay Telehany

Undergraduate Honors Theses

Our research group has previously discovered that a Cys residue within a transmembrane (TM) helix can directly photo-crosslink to a membrane lipid via an oxythiolation addition reaction to the double bond within the lipid, with a reaction yield of 10-20%. The pH-low Insertion Peptide (pHLIP) serves as our model TM helix, while the POPC lipid bilayer is our model membrane. We had long believed that the Trp residues within the sequence of pHLIP served as the key chromophore for this reaction, and thus they were essential for the formation of the TM helix-lipid adduct. To test this hypothesis, I synthesized …
