This quantitative correlational study investigates caregivers’ attitudes toward sexual behavior and sex education for children with Down syndrome, drawing upon the theories of reasoned action and planned behavior. Data was collected from a convenience sample of 112 caregivers. The analysis revealed significant positive associations between caregivers’ attitudes toward sexuality and their perspectives on sex education. Binary logistic regression indicated that higher POS scores predict increased likelihood of endorsing sexual behavior and supporting sex education for children with Down syndrome. Notably, demographic factors such as gender, age, and educational level did not significantly influence caregivers’ decisions regarding sex education support. The …

Predictors Of Counselors Accurately Diagnosing Obsessive Compulsive Disorder (Ocd) And Recommending Ocd-Specific Empirically Supported Treatments (Ests), Natalie Grierson

Walden Dissertations and Doctoral Studies

Research has supported that obsessive-compulsive disorder (OCD) is frequently misdiagnosed and not treated with OCD-specific, empirically supported treatments (ESTs) by healthcare professionals, resulting in negative consequences. Empirical findings are mixed regarding what predicts this and if counselors contribute to the concerns; therefore, it is imperative to investigate this with counselors. Using a medical model framework, the purpose of this quantitative study was to (a) examine the rate of counselors in the United States accurately diagnosing OCD, (b) identify the predictors for counselors accurately diagnosing OCD, (c) examine the rate of counselors recommending OCD-specific ESTs, and (d) identify the predictors for …

Relationship Between Sports Participation, Weight Intentions, And Insufficient Sleep On E-Cigarette Use Among U.S. High School Students, Stephanie Deivert

Walden Dissertations and Doctoral Studies

Despite public health efforts, e-cigarette use among youths persists, posing risks due to high nicotine content and the potential for transitioning to traditional cigarette smoking. Although sports participation has shielded individuals from traditional cigarette use, recent studies revealed a higher susceptibility to e-cigarette use among young athletes, though influencing factors were unexplored. Using the socioecological model, this retrospective cross-sectional study examined the relationship between sports participation, weight intentions, insufficient sleep, and e-cigarette use among U.S. high school students by analyzing 2021 National Youth Risk Behavior Survey data. Binary logistic regression assessed associations between variables. An interaction term examined the moderating …

The Integration Of Social Work Values And Principles In Police Work, Dasha Rhodes, Taylor Geyton, Jam Ost

School of Social Work Faculty Publications and Presentations

Persisting social inequities and injustices were spotlighted in the United States in 2020 after the murders of Breonna Taylor and George Floyd. A particular focus on the interactions of police officers and non-violent community members rallied a call to reallocate funds to social services better equipped to handle such situations, aptly named #defundthepolice. Many called for the need and placement of social workers in police agencies to curtail the negative interactions witnessed between police officers and communities of color, specifically with Black Americans. Across the nation, social workers are not always employed or readily available in police organizations. Therefore, instilling …

Essays On Multivariate Risk, Lin Zhou

Lingnan Theses (MPhil & PhD)

The essays focus on the analysis of multivariate risk, and they present insights in three papers. The first paper extends stochastic dominance to bivariate analysis by incorporating a reference function. Our approach offers flexibility in the selection of a reference function, improving upon previous studies by addressing their limitations more cohesively. The second paper explores a general choice-theoretic characterization of the duality that exists between a mean-utility-preserving increase in correlation and an increase correlation aversion. This sheds light on monotone comparative statics and characterizes cross-partial derivatives of the utility function. The last paper investigates optimal prevention in the presence of …

School of Integrative Biological & Chemical Sciences Faculty Publications

Summary

• Future climate presents conflicting implications for forest biomass. We evaluate how plant hydraulic traits, elevated CO2 levels, warming, and changes in precipitation affect forest primary productivity, evapotranspiration, and the risk of hydraulic failure.
• We used a dynamic vegetation model with plant hydrodynamics (FATES-HYDRO) to simulate the stand-level responses to future climate changes in a wet tropical forest in Barro Colorado Island, Panama. We calibrated the model by selecting plant trait assemblages that performed well against observations. These assemblages were run with temperature and precipitation changes for two greenhouse gas emission scenarios (2086–2100: SSP2-45, SSP5-85) and two CO2 levels (contemporary, …

Developing And Testing Low-Cost Air Cleaners For Safer Spaces During Wildfires, Brett W. Stinson, Elliott T. Gall

Mechanical and Materials Engineering Faculty Publications and Presentations

Air cleaning reduces indoor exposure to fine particulate matter (PM2.5) during wildfire smoke events. However, resource and cost constraints may limit access to air cleaning during such an event, as both commercial devices and the higher-rated MERV filters that do-it-yourself (DIY) assemblies typically rely upon tend to be expensive and in short supply. With these constraints in mind, we developed and evaluated several configurations of a novel, DIY air cleaner that uses common household fabrics as filtration media. Clean air delivery rates (CADRs) of the devices were experimentally evaluated in two ways: first, with independent measurements of flowrates and single …

Faculty, Staff and Student Publications

Orofacial clefts (OFCs) are common congenital birth defects with various etiologies, including genetic variants. Online Mendelian Inheritance in Man (OMIM) annotated several hundred genes involving OFCs. Furthermore, several hundreds of de novo variants (DNVs) have been identified from individuals with OFCs. Some DNVs are related to known OFC genes or pathways, but there are still many DNVs whose relevance to OFC development is unknown. To explore novel gene functions and their cellular expression profiles, we focused on DNVs in genes that were not listed in OMIM. We collected 960 DNVs in 853 genes from published studies and curated these genes, …

Optimization Of A Sers-Based Vertical Flow Immunoassay Utilizing A Plasmonic Syringe Filter For Rapid Biomarker Detection And Quantification, Anthony Abeiku Amissah

Theses and Dissertations

Many current diagnostic tools for accurate disease detection and quantification are often tedious and involve multiple complex steps. Consequently, there is a critical need for alternative point-of-care devices that are affordable and deliver rapid and reliable results. Recently, surface-enhanced Raman spectroscopy (SERS) has emerged as a highly effective analytical method, enhancing Raman scattering of molecules adsorbed onto nanoparticles and allowing for low-level detection and quantitative chemical analysis. In this study, we employ SERS to develop a rapid diagnostic test using human immunoglobulin G (hIgG) as a model biomarker because it is abundant in human serum, cheap, readily available, and well-understood. …

Multi-Symplectic Method For The Two-Component Camassa–Holm (2ch) System, Xiaojian Xi, Weipeng Hu, Bo Tang, Pingwei Deng, Zhijun Qiao

School of Mathematical & Statistical Sciences Faculty Publications

In this paper, the multi-symplectic formulations of the two-component Camassa–Holm system are presented. Both the multi-symplectic structure and two local conservation laws of the generalized two-component Camassa–Holm model are proposed for its first-order canonical form. Then, combining the Fourier pseudo-spectral method in the spatial domain with the midpoint method in the time dimension, the multi-symplectic Fourier pseudo-spectral scheme is constructed for the first-order canonical form. Meanwhile, the discrete scheme of the residuals of the multi-symplectic structure and two local conservation laws are also provided. By using the multi-symplectic Fourier pseudo-spectral scheme, the evolution of one- and two-soliton solutions for the …

Enterprise Systems: Installing And Configuring Erpnext On Macos, Yazan Abbasi

Senior Honors Theses

Enterprise Resource Planning (ERP) systems integrate business processes across organizations onto unified digital platforms through data and workflow consolidation. However, high licensing costs of proprietary ERP solutions like SAP and Oracle limit adoption for small and medium enterprises. This led to the emergence of open-source ERP alternatives like ERPNext which provide sophisticated capabilities at much lower total cost of ownership. However, ERPNext faces documentation gaps that hamper onboarding, customization, and widespread adoption. Accelerating ERPNext implementation by developing a comprehensive installation and configuration guide tailored for developers using Mac environments will be examined furthermore.

The background on ERP systems explores critical …

Paley, Nicole Linskey, Ryan Agnew, Paulo Henrique Arantes De Faria, Annie Feng, Sophia Y. Li, Elisha D. O. Roberson, Philip A. Ruzycki, Ekaterina Esaulova, Jennifer Laurent, Lacey Feigl-Lenzen, Luke E. Springer, Chang Liu, Wayne M. Yokoyama, Et Al.

2020-Current year OA Pubs

HLA-B*27 was one of the first HLA alleles associated with an autoimmune disease, i.e., axial spondyloarthritis (axSpA) and acute anterior uveitis (B27AAU), which cause joint and eye inflammation, respectively. Gastrointestinal inflammation has been suggested as a trigger of axSpA. We recently identified a bacterial peptide (YeiH) that can be presented by HLA-B*27 to expanded public T cell receptors in the joint in axSpA and the eye in B27AAU. While YeiH is present in enteric microbiota and pathogens, additional evidence that pathogenic T cells in HLA-B*27-associated autoimmunity may have had a prior antigenic encounter within the gastrointestinal tract remains lacking. Here, …

Cerebrospinal Fluid-Based Spatial Statistics: Towards Quantitative Analysis Of Cerebrospinal Fluid Pseudodiffusivity, Yutong Chen, Hui Hong, Arash Nazeri, Hugh S Markus, Xiao Luo

2020-Current year OA Pubs

BACKGROUND: Cerebrospinal fluid (CSF) circulation is essential in removing metabolic wastes from the brain and is an integral component of the glymphatic system. Abnormal CSF circulation is implicated in neurodegenerative diseases. Low b-value magnetic resonance imaging quantifies the variance of CSF motion, or pseudodiffusivity. However, few studies have investigated the relationship between the spatial patterns of CSF pseudodiffusivity and cognition.

METHODS: We introduced a novel technique, CSF-based spatial statistics (CBSS), to automatically quantify CSF pseudodiffusivity in each sulcus, cistern and ventricle. Using cortical regions as landmarks, we segmented each CSF region. We retrospectively analyzed a cohort of 93 participants with …
