Leveraging Interdisciplinary Expertise In Developing An Alternative Mathematics Pathway, Beverly Wood, Debra T. Bourdeau

Journal of Mathematics and Science: Collaborative Explorations

How many instructors does it take for amazing course design? Or perhaps we should begin with “A mathematician, humanist, communication expert and statistician walk into a bar.” This unlikely team has co-developed a pair of courses, Learning to Reason I: Art and Quotient and Learning to Reason II: Commerce and Flux, that deeply investigate quantitative reasoning from multiple perspectives. Blending elements of rhetoric, logic, and history with mathematical computation, representation, and application breaks through the perceived barriers between the unyielding, obstinate world of mathematics and the ambiguous, equivocal world of the humanities. Developing the courses as an interdisciplinary team of …

Using A Non-Destructive Method To Estimate The Number Of Contributors And Predict Dna Yield In Touch Dna Mixtures, Christin Lee

Master of Science in Forensic Science Directed Research Projects

Touch DNA samples are low templates and often are mixtures, making them typically one of the most difficult types of evidence to interpret. Short tandem repeat analysis is a standard method to estimate the number of contributors and DNA yield for each contributor; however, there are some limitations. Applying a non-destructive pre-DNA analysis technique that provides information about the touch DNA may improve the casework process. Antibody probes to hormones such as testosterone and dihydrotestosterone (DHT), and proteins including cytokeratins (CK) inside epidermal cells, have been demonstrated to produce a personalized signature for human touch cell populations. Testosterone, DHT, and …

The Analysis Of Commercially Available Kratom Products In Richmond, Virginia, James H. Fleming Jr

Master of Science in Forensic Science Directed Research Projects

Kratom is a novel psychoactive substance that has gained popularity within the past ten years. Originating from Southeast Asia, the leaves of the Mitragyna speciosa tree contain two principal alkaloids, mitragynine and 7-hydroxymitragynine, that play a key role in opioid-like effects. Twenty-nine kratom products were obtained from tobacco shops in the Richmond, Virginia area, including powders, teas, capsules, extracts, and a carbonated beverage. Samples were analyzed using Direct Analysis in Real Time-Mass Spectrometry (DART-MS) for kratom alkaloids, labeled ingredients, and other possible organic compounds. Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES) was used to quantitate aluminum, arsenic, copper, iron, magnesium, nickel, …

Master of Science in Forensic Science Directed Research Projects

In the past 20 years, the rate of opioid use increased drastically in the United States. The country has experienced an enormous number of deaths caused by opioid overdose, opioid use disorder (OUD), as well as other harms as a consequence of the high numbers of opioid prescriptions. Fentanyl, a well-known synthetic opioid, has been a contributor to the opioid crisis since 2013 due to its popularity in clinical and illicit use. It has a high potency, which makes it an effective analgesic but a dangerous illicit substance. A new synthetic opioid, bucinnazine, has recently become a new black-market opioid …

Optimization Of A Microfluidic Device For Cell Capture Using Optical Trapping, Samantha C. Pagel

Master of Science in Forensic Science Directed Research Projects

Biological mixtures which result from evidence produced in sexual assault cases are one of the most common types of mixtures observed in forensic biology casework and have contributed to evidence backlogs across the country. In the forensic community, this has highlighted the need for a more efficient cell separation method at the beginning of the DNA analysis workflow than the currently accepted method. One promising novel front-end cell separation technique is optical trapping. In heterogeneous mixtures, optical tweezers have been demonstrated to manipulate and isolate cells of interest from other cell types.

The current study sought to establish child-inspired codes that would better reflect the sample.

Methods: Children aged 5-12 years (M=8.82, 48.9% female) and their caregivers were recruited from high-poverty urban US areas. All participants identified as Black or African American. Children were audiotaped while speaking, uninterrupted, for three minutes about …

A Marginal Identity Model For Those In The "In-Between", Francine S. Singson, Sonia Meyer, Christine A. Reid

Graduate Research Posters

Background: In existing models exploring the formation cultural identity, there is emphasis on development from the perspective of race or country of origin. While these models have made significant contributions to the study of identity development in the fields of counseling and psychology, research on the identity development of people who exist within the spectrum between traditionally acknowledged identities (Deaf/Hearing, LGBTQIA+, first/second generation) is lacking.

Methods: To explore the merit of establishing a distinct theory exploring development of individuals whose identities exist between the existing binaries of identity, a systematic review and analysis of current literature was performed. …

Trajectories Of Medication Non-Adherence With Time-Varying Predictors And Association With Health Outcomes: A Comparison Of Classical Statistical Methods With Machine Learning Algorithms, Vasco Pontinha

Theses and Dissertations

Background: Medication adherence is a major obstacle to improving health care outcomes in long-term therapies for chronic diseases. According to the World Health Organization, interventions for improving medication adherence can have a higher impact on the health of the population than any other advance in medical treatments. Approximately 125,000 individuals die every year in the U.S. because of non-adherence to medication, representing societal costs of $100-289 billion. Previous research has successfully used group-based trajectories methods to identify similar longitudinal medication adherence trajectories. However, medication adherence is not an isolated behavior and is influenced by many factors that current interventions fail …

Optimization And Comparison Of Methods For Separation Of Spermatozoa From Superabsorbent Polymer-Containing Forensic Evidence, Hannah Wells

Master of Science in Forensic Science Directed Research Projects

Sexual assault is currently one of the most prevalent crimes that affects victims of all ages. Forensic DNA analysts often confirm proof of contact in sexual assault cases through the identification of spermatozoa and subsequent STR profiling. Diapers and other feminine hygiene products, such as maxi pads and ultrathin pads, are types of superabsorbent polymer-containing evidence that complicate the process of DNA analysis due to the trapping of the spermatozoa in the gel-like matrix. In this study, a comparison of methods was performed to determine which extraction technique produces the highest sperm cell and DNA yield and generates a usable …

Low Loss Plasmon-Assisted Integrated Photonics, Dhruv Fomra

Theses and Dissertations

Photonic integrated circuits (PICs), semiconductor chips with both photonic and electronic elements, are seeing rapid development and have the potential to transform several industries, such as autonomous driving, computing, telecommunication and quantum networks. However, realization and wide adoption of PICs across the various fields faces a key challenge – soze disparity between electronic (~0.01 um) and photonic components (~100’s of um). Plasmonics, a technology which confines light to the interface of metals and dielectrics, has a potential to address challenges. In particular, it has been shown to led to smaller devices (~10 um or less), enabling higher density optical circuits …

Classification And Differentiation Of Forensically Relevant Cell Populations Using Imaging Flow Cytometry, Arianna D. Decorte

Master of Science in Forensic Science Directed Research Projects

Forensic casework relies heavily on DNA profiles which may be time-consuming to generate and difficult to interpret when biological mixtures are present. Additionally, there are significant challenges in using sub-source data alone to answer the activity-level questions often most pertinent in criminal cases. Source level information can add critical probative value, however, methods that can provide information as to the source tissue of evidentiary cell populations are limited. There remains a need for new methods that can differentiate between and classify various cell populations, particularly for vaginal and epidermal tissue, since there are no conventional serological techniques specific to these …

Sharing Vision For Shared Spaces: Mobile Immersive Planning And Community-Led Design Of Green Spaces In Richmond’S Southside, Maria T.E. Dougherty

Master of Urban and Regional Planning Capstone Projects

This plan seeks to demonstrate the potential of immersive technologies, specifically augmented reality, in strengthening public engagement and enabling the collaborative, community led design of local green spaces.

Community engagement, while now a focal point of urban planning education, is still implemented in uneven strategies that often further distance the public from the process and understanding of city vision; new paradigms of outreach and community-government knowledge sharing must be explored to overcome common constraints of time, expertise, and language that prevent public participation in projects that directly impact their health. Immersive urban planning offers a way to bring people into …

Food Systems Financing Action Plan, Noah Holmes Foster

Master of Urban and Regional Planning Capstone Projects

Food insecurity is a well-documented issue in Virginia and throughout the United States. Food enterprises, especially those in under-resourced communities, often lack access to the credit needed to start or expand their operations due to the narrow profit margins of food enterprises. Community development financial institutions (CDFIs), such as Virginia Community Capital (VCC) address this issue by providing low-interest financing to food businesses that can increase food security and strengthen local economies. Food systems financing is a developing field for VCC and other CDFIs, and changes to standard practices are required to ensure that lending is as accessible as possible …
