The Mediating Role Of Emotion Regulation Between Parent-Child-Relationship Quality And Psychological Health Of Adolescent Girls, Ethan M. Rick
McNair Scholars Research Journal
Emotion regulation plays a crucial role in adolescent psychological health and is influenced by the quality of parent-child relationships. Prior research suggests that supportive relationships foster adaptive emotion regulation, while conflict-ridden relationships contribute to emotion regulation difficulties, leading to negative psychological outcomes. This study examines the mediating role of emotion regulation difficulties in the association between mother-daughter relationship quality and adolescent psychological maladjustment, including anxiety, depression, and disordered eating. A sample of 106 adolescent girls (ages 11–21) in the United States completed self-report measures assessing relationship closeness and discord, emotion regulation difficulties, and psychological distress.

Zero-Tolerance Discipline In American Schools: Racial Injustice In The Age Of Youth Disposability, Trinity J. Perkins
Zero-Tolerance Discipline In American Schools: Racial Injustice In The Age Of Youth Disposability, Trinity J. Perkins
McNair Scholars Research Journal
This study critically examines how neoliberal social controls and school-based criminalization efforts emerged in response to a series of moral panics surrounding perceived increases in school violence and mass shootings. Largely, this response manifested in the form of rigid zero-tolerance disciplinary policies focused on deterrence and retribution. However, research reveals the application of these policies produce racial and income-based disparities in how school discipline is administered, which contributes to the school-to-prison pipeline (i.e., a pathway for youth to be funneled out of education and into incarceration). As such, it is believed that racial threat dynamics may be contributing to the …
Mental Health Implications Of Substance Use Among Queer College Students, Samia L. Neeley
Mental Health Implications Of Substance Use Among Queer College Students, Samia L. Neeley
McNair Scholars Research Journal
Studies reveal that sexual minorities are at greater risk for tobacco and nicotine use (Harlow et al., 2023). In addition, experiences with discrimination and harassment are related to substance use in queer adults (Blackwell & López Castillo, 2020). Building on previous research, this study aims to investigate the relationship between substance use, mental health, and sexual/gender identity among queer college students. We asked undergraduate students (anticipated N = 100) to report their alcohol, e-cigarette, and cannabis use as well as depression and anxiety symptoms. We anticipate that queer students will report greater substance use and greater mental health challenges than …

Artificial Intelligence (AI) is swiftly transforming the world, yet its environmental impact is often unknown. Training AI models, deploying AI models, and storing large volumes of AI’s data in data centers all contribute to both positive and negative environmental outcomes. While many studies highlight the benefits of AI, there are also a few that address how AI’s widespread use results in unsustainable environmental impacts. This literature review investigates the negative environmental impacts of AI, including environmental degradation, increased energy consumption, and carbon emissions. From the rise of unpredictable weather and natural disasters, to the melting of icebergs, the impact of …
Differential Effects Of Amiloride And Benzamil On Salt Taste Physiology And Behavior: The Case For Phasic Responses In The Generation Of Sodium Appetite, Amyra M. Issa
McNair Scholars Research Journal
The current experiment aims to investigate the relationship between the early phasic portion of salt taste transduction and sodium appetite. Prior research has identified two salt transduction pathways: a sodium-selective pathway, which is inhibited by amiloride or benzamil, and a non-selective pathway, which is insensitive to these blockers (Breslin & Spector, 2008). When presented with sodium solutions, sodium-depleted mice exhibit a behavior termed the “sodium appetite,” which results in voracious sodium consumption. The prevailing theory is that this behavior depends on neural activity of sodium-selective neurons (Breza & Contreras, 2012; Roitman & Bernstein, 1999). While previous studies have demonstrated that …
Contrasting Disparities Between Desi Populations And The Michigan Healthcare System In The Metro Detroit Atrea, Ramin Areeb
Contrasting Disparities Between Desi Populations And The Michigan Healthcare System In The Metro Detroit Atrea, Ramin Areeb
McNair Scholars Research Journal
This study investigated the healthcare disparities experienced by the Desi population (Indian, Pakistani, Bangladeshi, Sri Lankan, Nepali, etc.), ages 18 and higher, in the Metro Detroit area. Despite the ever-growing population of South Asian communities in the United States, research on their interactions with Michigan healthcare remained very limited. The lack of consistent reports, population-specific studies, and overall popularity of the discussion proves this. Using a survey-based methodology, this study collected accounts from participants regarding their healthcare experiences, perceived inequities, and barriers to accessing high-quality medical services. The data then underwent a thematic review to identify recurring patterns, including issues …

Neural Network Model Watermarking Using Quantized Least Significant Bits And Pseudorandom Error-Correcting Codes, Ranjit Kumaresam, Srinivasan Raghuraman, Ka Log Ng
Defensive Publications Series
The present disclosure relates to watermarking techniques for neural network models that embed verifiable ownership information into model parameters. In one aspect, floating-point weight parameters are quantized and least significant bits are biased during rounding such that the bits collectively encode a pseudorandom error-correcting code derived from a digital signature of a model owner. In another aspect, a pseudorandom codeword generated from the digital signature is directly embedded by replacing least significant bits of quantized weight parameters. In both cases, the watermark is cryptographically verifiable and remains detectable even after model perturbations, fine-tuning, or partial retraining. Ownership verification is performed …

Hybrid Offline-To-Real-Time Architecture For Context-Aware Keyword Insertion, Karen Yao, Indu Ramamurthi
Defensive Publications Series
A Hybrid Offline-to-Real-Time Architecture generates context-aware ad copy while meeting the latency constraints of live ad auctions. In an offline phase, a large language model (LLM) analyzes a product catalog to pre-generate ad copy templates that contain semantic placeholders. During the real-time ad auction, a lightweight engine parses a user’s search query to extract contextual intent. The system then selects an appropriate template and injects the extracted intent into the placeholders to assemble the final ad copy. This two-pass approach decouples the computationally intensive LLM generation from the time-sensitive ad serving process, providing the semantic quality of LLM-generated text at …

Learning Trajectories Of Online Batch Selection Methods, Luke Green
Learning Trajectories Of Online Batch Selection Methods, Luke Green
Theses and Dissertations
Modern deep neural networks achieve strong performance on large-scale datasets, but often require substantial training time. Online batch selection methods seek to reduce this cost by updating models on informative subsets of each batch rather than on all available examples. Recently introduced methods leverage teacher models and report substantial speedups, particularly in noisy-label settings. However, comparisons are often based on the number of epochs required to reach a target test accuracy, a coarse metric that is sensitive to implementation details and may obscure important differences in learning dynamics. In this thesis, we implement several online batch selection methods in a …

Beyond Single Images: A Comprehensive Benchmark For Album-Level Vision-Language Understanding, Shawn Huang
Theses and Dissertations
Automatic album organization has been studied extensively over the past decades due to significant progress in digital photography. Recent Vision-Language Models (VLMs) have shown strong performance on multi-image understanding, making them natural candidates for automating album organization workflows. While VLMs’ abilities in multi-image understanding have been widely studied, their performance on album organization remains underexplored. To bridge this gap, we introduce AlbumBench, the first comprehensive benchmark for automatic album organization. Specifically, we (1) define album organization tasks as photo selection for album-specific user objectives, photo rating according to how well user intents are fulfilled, and album-specific photo grouping given a …

To evaluate the structural, optical, and morphological properties of the resulting nanoparticles, both sets of samples were characterized using UV-Vis spectroscopy, XRD, energy-dispersive X-ray spectroscopy (EDX), FTIR, and Field Emission Scanning Electron Microscopy (FESEM). The XRD patterns confirmed the successful formation of a hexagonal wurtzite …
