Mental health professionals lack unified screening guidelines for CODs, limiting early detection and coordinated care, especially in high-risk populations. This project aims to develop an evidence-based clinical practice guideline (CPG) to promote interprofessional consensus and improve COD screening and management. Guided by the Johns Hopkins EBP Model and the AGREE II instrument to ensure rigor. Twelve expert reviewers (5 PMHNPs, 4 LCPCs, and 3 psychiatrists) assessed a CPG developed from nine critically appraised studies sourced from EBSCO, CINAHL, and …

Humidity Control Apparatus And Materials, Ying Zhong

USF Patents

A ventilation port maintains the humidity range within a sealed or partially sealed enclosure maintaining a level of atmospheric moisture such as a greenhouse. The port is comprised of a polymer blend film made of a hydrophilic component serving as the water-absorbing material and substrate component serving as the mechanical backbone. The film is designed to bend and open the port when the humidity within the enclosure exceeds a predetermined level outside the humidity range, allowing for the venting of excess humidity. Once the humidity falls back within the desired range, the film returns to its original state and closes …

Analyzing The Impact Of Passive Techniques On Aircraft Wing Hysteresis: An Experimental And Numerical Study, Brendan Worton

Masters Theses

This study investigates the effects of passive flow control techniques on aerodynamic hysteresis primarily in NACA 2412 (cambered) and 0012 (symmetric) wings. Computational Fluid Dynamics (CFD) was used to design and evaluate three passive techniques, including outward-facing dimples, leading-edge tubercles, and rectangular vortex generators, prior to experimental validation. These techniques demonstrated improvements in aerodynamic performance in CFD simulations and were therefore selected for wind tunnel testing to analyze their aerodynamic performance and influence on hysteresis behavior.

The realization that the cell is abundantly compartmentalized into biomolecular condensates has opened new opportunities for understanding the physics and chemistry underlying many cellular processes, fundamentally changing the study of biology. The term biomolecular condensate refers to non-stoichiometric assemblies that are composed of multiple types of macromolecules in cells, occur through phase transitions, and can be investigated by using concepts from soft matter physics. As such, they are intimately related to aqueous two-phase systems and water-in-water emulsions. Condensates possess tunable emergent properties such as interfaces, interfacial tension, viscoelasticity, network structure, dielectric permittivity, and sometimes interphase pH gradients and electric potentials–. …

Correlations Of Intersectional Identity Cohesion And Growth In Queer And Transgender Black, Indigenous, And People Of Color, Zoha T. Qader

Master's Theses

Past research has found that identity cohesion (how integrated multiple identities are) is a protective factor that moderates the relationship between intersectional microaggressions and mental health outcomes. Individuals with higher identity conflict (multiple identities clashing) had anxiety and depression symptoms that could be predicted by the distress they experienced from intersectional microaggressions. For those with high identity cohesion, this was not the case. While compelling, the question remains, what are the factors that contribute to identity integration versus identity conflict? The present study will utilize existing data of 417 QTBIPOC individuals. Ratings of LGBTQ+ community belonging and engagement, and LGBTQ+ …

Effect Of Bond Strength Variation And Ionizing Radiation On Mutations In Cytosine-Guanine Islands, Joshua Robert Bedwell, Yan Poniatovskyi, Vola Andrianarijaona

Achieve

Ionizing radiation produces free electrons within cells which then ionizes DNA and has the potential to cause carcinogenic mutations. Cytosine-Guanine (CpG) islands are regions that are rich in cytosine and guanine bases and are common sites of single point mutations and strand breaks. In this study, density function theory (DFT) is used to calculate the potential energy of DNA nucleotide dimers varying bond lengths in five different ionized states. Crossing between two ionized states can be seen in the potential energy curves, indicating the possibility of natural transition between the two states. Potential energy curves are used to determine bond …

Analyzing The Strength Of The Amine Bond Of Guanine Via Potential Curve Analysis: A Computational Approach, Yan Poniatovskyi, Joshua Robert Bedwell, Vola Andrianarijaona

Achieve

The deamination of guanine can be a cause of single point DNA mutations. In this study, the strength of the amine bond was examined using DFT and B3LYP to map out the bond’s potential curves under conditions of various charges being imposed on the molecule. Such an approach yielded a few potential curves that do not exhibit the expected behavior and rather, show crossings in potential energy curves. Discussions regarding the suspected causes of these unexpected behaviors are included in the poster presentation. The Mulliken charge analysis of guanine under these conditions is coherent with the proposition that the deamination …

An Educational Intervention Focused On Identifying Adverse Childhood Experiences, Laconia Bacon

Walden Dissertations and Doctoral Studies

Adverse childhood experiences (ACEs) refer to traumatic childhood experiences that individuals may have been exposed to during their youth, such as child maltreatment, domestic violence, or interparental violence. Research has demonstrated that experiencing ACEs in childhood may result in physical and mental illnesses that led to dangerous lifestyle patterns in adulthood. In the local organization, several patients with ACEs presented in the emergency department (ED). The nurses, unaware of ACEs, were unable to detect and respond to the consequences of ACEs. Thus, the purpose of this Doctor of Nursing Practice (DNP) project was to determine whether an educational intervention focused …

Machine Learning Research On Time Series Data, Zeyi Fan

Lingnan Theses (MPhil & PhD)

Time series generated by complex systems, such as industrial IoT and user behavior systems, confront two core challenges: structured missingness (e.g., continuous or periodic gaps) that disrupt temporal dependencies, and the difficulty in effectively modeling dynamic long- and short-term temporal dependencies inherent in evolving patterns (e.g., user interests). Traditional approaches struggle to balance the preservation of local dependency continuity and the rational association of global long-range dependencies in structured missing scenarios, often incurring high computational costs. In temporal pattern modeling, the lack of adaptive mechanisms to fuse evolving long- and recent behavior trends (e.g., stable interest inertia vs. short-term preference …

The Intersection Of Social Groups And The Self, Zachary Robert Auwerda

Electronic Theses and Dissertations Archive

This dissertation explores the nature of social identity by examining both the collective identity of groups and the social selves of individuals. I start by offering a Humean model of collective identity. On this model, the metaphysical nature of group persistence depends on our psychological dispositions and our explanatory goals. On this view, collective identity is a fiction—something that humans ascribe to a group—rather than something that exists independently. I argue that this Humean model has advantages over structural and intentional theories of group persistence. I then move onto the topic of social construction and its incompatibility with methodological individualism. …

Teaching Bilingual Learners With Dysgraphia, Angela Gonzalez-Urbina

Masters Projects

With the push for legislation on the Dyslexia law in Michigan and elsewhere, teachers need to understand what dyslexia and dysgraphia are to support all students. An extra understanding is necessary in bilingual education and reading challenges because they use two language systems in and out of the classroom. Reading and writing are already areas that impact the working memory of the learner; adding dysgraphia to that proves to be more of a challenge. Dysgraphia can coexist with dyslexia, and individuals with dysgraphia often experience difficulties with spelling and writing speed. This project introduces dysgraphia as one of the reading …

Investigation Of A Divergent Triangle Construct For Internal Fixation Of Vertical Femoral Neck Fractures Using Experimental And Finite Element Analysis Methods, Hannah Rainey

Masters Theses

Hip fractures are a significant public health issue as they are a commonly encountered problem and have a high rate of mortality. The fracture of the femoral neck is difficult to treat due to the geometry of the proximal femur and the weight-bearing capacity that the structure must comply with. Internal fixation of the femoral neck is often accomplished with three screws inserted along the axis of the femoral neck. The optimal configuration and number of these screws is not agreed upon in the literature. The purpose of this study was to conduct a pilot investigation on the biomechanical performance …

BACKGROUND: In the FUEL (Fontan Udenafil Exercise Longitudinal) trial, a positive treatment effect was identified for outcomes at the ventilatory anaerobic threshold but not for the primary outcome, oxygen consumption (Vo₂ in participants with near-normal baseline exercise performance.

METHODS: Participants were divided into subgroups by baseline predicted peak Vo₂ (< 80% versus ≥80%). Treatment effect was evaluated in those with a baseline peak Vo2 < 80% predicted and linear regression was performed to examine the interaction between subgroup and response to therapy for the primary and secondary outcomes.

RESULTS: Of the 379 participants with paired exercise data, 302 (80%) had a baseline peak Vo₂ < 80% predicted. In this subgroup, the primary outcome of peak Vo₂ improved significantly after 6 months of udenafil treatment, when compared with placebo (0.23±4.17 mL/kg per min versus -0.90±3.74 mL/kg per min; P=0.021). Secondary outcome measures, including Vo₂ at …
