Environmental Justice And Soil Lead Contamination: Spatial Analysis Across Seven Community Areas, Arsene Lionel Apabaga

DePaul Discoveries

Pb is a pervasive metal with toxicity linked to numerous human health issues. Urban soil is a well-documented environmental sink for Pb, persisting as a legacy pollutant decades after the phaseout of leaded gasoline. This study measured, mapped, and analyzed the spatial distribution of total soil Pb concentrations across seven Chicago Community Areas (CCAs). The objectives were to: (1) assess the relationship between mean soil Pb concentration and mean Community Environmental Justice Index (CEJI) score per CCA, (2) determine the relationship between soil Pb levels and the percentage of industrial land use, and (3) quantify and compare the percentage of …

Values And Barriers: A Multidimensional View Of College Students’ Motivations To Volunteer, Gavin Warner, Quang Anh Nguyen, Ansuk Jeong

DePaul Discoveries

University students tend to have ample access to many resources for volunteering and so are in a unique position among Americans. With all the benefits of volunteering outlined in past research, the students training to become leaders in their fields may have the most to gain from volunteerism. It is surprising, then, to note that young people are less likely to volunteer than other age groups. Why is it that college students tend to volunteer at such low rates? The current study seeks to answer this question through a mixed-methods survey. A qualitative section clarified which specific barriers students felt …

The Role Of Maternal Attachment In The Relation Between Acculturative Stress And Mental Health Among Latinx Youth, Melisa Dangles, Evelin Regalado, Antonio Polo

DePaul Discoveries

Acculturative stress is a significant psychological challenge faced by Latinx youth as they navigate cultural adaptation, often leading to negative mental health outcomes. Research has shown that acculturative stress is positively associated with major depression, anxiety, and high-risk behaviors, including delinquency and impulse control problems (Lerias et al., 2024). This study examines the role of maternal attachment as a mediator in the relation between acculturative stress and both depressive symptoms and externalizing problems among Latinx youth. The sample consisted of 281 Latinx students (ages 10-14, M = 11.4, SD = 0.95) from several Chicago Public Schools. Results indicate that acculturative …

“Put Me In Coach!”: The Impact Of College Sport Team’S Mentorship In Chronically Ill And Disabled Children And Adolescents Adherence To Medical Regimen, Jameela Askira

DePaul Discoveries

The current study solely analyzed answers to questions regarding adherence to medical treatments. There were three measures: Child vs Parent Response, Treatment Regimen Components and Care Responsibility. Through a descriptive …

Frustrated, But Motivated: Insights From People With Me/Cfs, Aiden Rathmann, Suvetha Ravichandran, Leonard A. Jason

DePaul Discoveries

Qualitative research can amplify and clarify the perspectives of people with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). The current study analyzed responses to an open-ended survey question regarding the experiences of people with ME/CFS, especially in relation to ME/CFS case definitions. Although many people with ME/CFS are frustrated with their interactions with healthcare workers and researchers, people with this illness want these individuals to listen to them about their experiences with health care and research.

Using Synchrotron Wide-Angle X-Ray Scattering To Study Collagen Degradation In Second Metacarpal Bones, Zeel Sheth, Misha Romanov, Ruby Schwieger

DePaul Discoveries

The study examines female human second metacarpal (mc2) bones from early medieval cemetery at Greding, Germany, using high-energy Wide-Angle X-ray Scattering (WAXS) at beamline 1-ID of the Advanced Photon Source (APS) at Argonne National Laboratory. Rietveld refinement showed that carbonated apatite lattice parameters did not correlate with estimated age-at-death. For six of the mc2, widths of 00.2 and 00.4 diffraction peaks were substantially narrower than those of a modern (non-diagenetically altered) mc2 and of the other four ancient mc2. The peak width results are interpreted as indicating that four of the ten ancient mc2 retain substantial collagen and six of …

Conical Radon Transform For Medical Imaging, Olivia Medina

DePaul Discoveries

The 2D Conical Radon transform is an alternate approach to medical imaging that is more efficient than the conventional method used in the PET Scan. Here, a 2D Conical Radon transform is used to reconstruct a function or image from a line integral on a 2-dimensional cone with a fixed angle and axis of symmetry at each data point. Implemented in MATLAB, this method uses a single Reimann Sum to produce images in a faster and less computationally expensive way. The V-Line transform is an alternative understanding of the 2D Conical Radon transform in which it is theoretically proven that …

Modifications To The Spiral Array: A Computational Approach To Music Analysis, Rose Bittle

DePaul Discoveries

The Spiral Array is a geometric model of musical tonality and exists as a tool in computer-aided music analysis. The model was first published in 2000 by Elaine Chew, PhD, in her thesis, Towards a Mathematical Model of Tonality. This project aimed to restructure the Spiral Array, limiting user ambiguity and optimizing the application of musical key finding. The existing model defines pitch, chord, and key location to form a series of spirals dependent on a set of flexible weights. In our research we were able to identify potential issues with the pitch definitions themselves and experiment with methods …

Exact Sampling Of The Six-Vertex Model Using Coupling From The Past, Malaeka Amir

DePaul Discoveries

This paper aims to explore the six-vertex model through simulations designed to investigate the behavior of configurations under specific domain wall boundary conditions. To generate random configurations, we employ the Markov Chain Monte Carlo method while addressing the challenge of mixing times by utilizing the Coupling from the Past (CFTP) algorithm. Implemented in Python, our approach leverages CFTP to ensure exact sampling, avoiding the uncertainty of convergence in traditional Monte Carlo methods. We explore the monotonicity property within this framework and prove that it is only maintained by the steps of this algorithm for very particular values of the parameters.

Modified 2-Quinolinones For Photocatalysis: The Fluorescence Quantum Yield (Φf) Of Novel 2-Quinolinone Derivatives, Reggina Moreno Trevino, Graham Griffin

DePaul Discoveries

The photophysical properties of novel 2-quinolinone derivatives were examined to evaluate their potential as photocatalysts using fluorescence and UV-Vis absorbance spectroscopy. The fluorescence quantum yields were determined via the relative comparative method, using target absorbance values at a specific wavelength to prepare solutions and comparing these measurements to the reference molecule carbostyril-124. Molar absorptivity values were also calculated to assess the light absorption properties for each compound. Among the derivatives, PAV-3 presented with the highest molar absorptivity and fluorescence quantum yield values (ε= 15297.3 M-1 cm-1, ΦF= 17.1%), while PAV-5 showed the lowest (ε= 4796.2 M-1 cm-1, ΦF= 2.3%). The …

Race/Ethnicity, Living Arrangements, And Access To Healthcare Among Older Adults With Alzheimer’S Disease In The United States: Multiple Systematic Reviews In Relation To Health Outcomes, Chela Reiss, Grace Vethacke

DePaul Discoveries

Alzheimer’s disease (AD) is a neurodegenerative condition primarily affecting older adults. It is a growing public health crisis that affects memory, thinking, and behavior. The number of adults aged 65 and older is projected to reach 98.2 million by 2060, leading to a continued rise in the prevalence of AD. Understanding the socioeconomic factors that influence health outcomes in patients with Alzheimer's Disease and Related Dementias (ADRD) is essential in addressing the disparities within patient care and quality of life. This systematic review examined three socioeconomic factors - race/ethnicity, living arrangements, and access to healthcare - and their related health …
