Examining the Impact of Racial Microaggressions and Psychological Distress in Latine Individuals: A Focus on PTSD, Anxiety, Depression, and Stress
No full textLatine individuals in the United States face distinct mental health challenges due to unique stressors, including systemic racism and discrimination. While research has established that racial microaggressions—such as daily slights, insults, and invalidations—negatively impact the psychological well-being of people of color, there remains limited scholarship specifically focused on Latine communities. This study examines different types of racial microaggressions—such as invisibility, criminality, and sexualization—as predictors of psychological distress among Latine individuals. A sample of 434 Latine participants completed measures assessing their experiences with racial microaggressions, as well as symptoms of depression, anxiety, stress, and trauma. Four multiple linear regression models were used to test the predictive relationship between different types of racial microaggressions and psychological distress. Findings indicated that racial microaggressions significantly predicted psychological distress, with racial microaggressions related to sexualization and invisibility emerging as particularly strong predictors. These results highlight the need for further research on protective factors that buffer against the effects of racial microaggressions and the importance of culturally responsive mental health interventions for Latine Americans
Quantitative Analysis of Psychological Safety, Resilience, and Intraminority Solidarity as Predictors of Racial Trauma Distress Among BIPOC College Students
No full textRacial trauma distress is when post-traumatic stress disorder symptoms occur due to repeated and cumulative experiences of racism and can negatively impact Black, Indigenous, and people of color (BIPOC). Consensus in research findings strongly suggests that BIPOC students are more likely to experience racism on university campuses than non-BIPOC students. To mitigate some of these negative outcomes, existing research has shown that psychological safety, resilience, and intraminority solidarity are protective factors for BIPOC students experiencing race-related distress. However, little is known about the frequency of racial trauma distress among BIPOC college students and how these variables may protect against racial trauma distress. This study examined whether psychological safety, resilience, and intraminority solidarity were significant predictors of racial trauma distress levels among BIPOC college students. Data were collected from 254 BIPOC college students recruited from a minority-serving institution in the southwest region of the United States (Mage = 19.45, SD = 3.00) who completed an online survey. A multiple regression model was used to examine whether the predictors significantly predicted racial trauma distress. Results suggest that psychological safety and resilience were significant negative predictors of racial trauma distress. However, intraminority solidarity was a significant positive predictor of racial trauma distress. This research contributes valuable insights into the interaction between psychological safety, resilience, intraminority solidarity, and racial trauma distress and the roles these variables play as potential mitigators against the race-based stress of racial trauma. Understanding the link between these factors and racial trauma distress is crucial for developing effective interventions to address the negative effects of racial trauma distress among BIPOC college students

The Influence of Nurse Union Size on Nurse Practitioner Full Practice Authority in the U.S.
No full textThe scope of practice for Advanced Practice Registered Nurses (APRNs) is a critical issue in healthcare policy, influenced by both demand for healthcare services and legislative action. This paper examines the impact of nurse union size on a state having full practice authority for nurse practitioners across the United States. Utilizing data from the Nurse Unionization Data Tool and controlling for several variables (right-to-work laws, physicians per capita, and personal healthcare expenditures per capita), this study employs multivariate logistic regression to analyze the relationship between the proportion of unionized nurses and the extent of practice authority granted by state laws. Findings indicate that larger nurse unions are significantly associated with full practice authority for nurse practitioners. The results underscore the importance of nurse unions in advocating for legislative changes that widen APRN autonomy. This study contributes to the broader discourse on the interplay between interest groups and healthcare policy, highlighting the potential of organized labor to influence professional practice boundaries in healthcare. Future research should examine mechanisms in which nurse unions exert influence and the impact of other stakeholders, particularly hospital and physician groups, whose spending may also shape scope of practice laws
Enhancing Student Engagement and Support With a Discord Ticketing and AI-driven FAQ System
No full textAs the CS 202 Coordinator overseeing seven sections per semester, I introduced a Discord-based ticketing system to streamline student support and engagement. Traditional methods like office hours and email often created delays, whereas the ticket system allows students to receive timely help from any available TA, regardless of section. To further enhance accessibility, we added a public FAQ channel that displays resolved tickets, helping students quickly find answers without combing through chat logs. This approach supports learners with shorter attention spans and builds a shared knowledge base. Additionally, we are compiling these interactions to train an AI chatbot capable of instantly answering common questions, allowing human staff to focus on more complex issues and continuously improving the course’s instructional support.https://oasis.library.unlv.edu/btp_expo/1204/thumbnail.jp

Anonymous Cyber Threat Intelligence Sharing on Blockchain
No full textIn cybersecurity, sharing of cyber threat intelligence (CTI) plays a pivotal role in our collective defense against emerging threats. However, the current paradigm of CTI sharing is one that participants are reluctant to share due to serious concerns about privacy and the potential exposure of sensitive information.We provide a comprehensive look at the potential of blockchain technology in cybersecurity, highlighting its advantages in creating an immutable, transparent, and decentralized ledger for CTI sharing. We also explore the mechanism of decentralized identity (DID) and explain how ZKP can be used to verify the authenticity of shared data without compromising the anonymity of participants. We detail the architecture of the proposed scheme, describing the application of an interplanetary file system (IPFS) for decentralized data storage, a private blockchain for transaction management and verification, and Zero-knowledge proof (ZKP) for privacy certification. Through this research, we demonstrate that a blockchain-based CTI sharing scheme significantly mitigates privacy concerns, encourages greater participation, and improves the overall resilience of cyber defenses. This dissertation concludes with a discussion of the implications of these findings for future cybersecurity practices, potential challenges in adopting blockchain and DID, and directions for further research. This research contributes to the field of cybersecurity by facilitating a more collaborative and effective approach to counter cyber threats, and by providing a new solution for secure and anonymous CTI sharing
Pre-Service Teacher Self-Efficacy for Classroom Management and Evidence Based Practices for Managing Classroom and Challenging Behaviors
No full textThis study investigated the relationship between pre-service teachers\u27 self-efficacy (TSE) and their knowledge of evidence-based practices. Teacher self-efficacy, defined as the belief in one\u27s ability to achieve specific teaching goals, plays a pivotal role in shaping teaching behaviors and student outcomes. Evidence-based practices, grounded in scientific research, are essential for effective teaching and problem-solving in diverse classroom settings. This study highlighted the importance of the two specific resources of self-efficacy and knowledge of evidence-based practices for managing classrooms and challenging behaviors. By exploring pre-service teacher resources, this study aimed to contribute to the body of literature exploring the challenges facing educators during their preparation and ultimately in the classrooms they will be responsible to effectively managing
Cross-Correlation Studies of the Cosmological 21 cm Signal And High-Redshift Galaxy Distributions
No full textThe Epoch of Reionization (EoR) marks a critical phase in cosmic history, during which time the first stars and galaxies ionized the surrounding neutral hydrogen gas. A powerful way to probe this period is by cross-correlating the 21 cm signal from neutral hydrogen with high-redshift galaxy distributions. In this study, we analyze the 21 cm-galaxy cross-power spectrum using simulated sky maps and explore its redshift evolution, revealing a transition from positive correlation at early times (high redshift) to anti-correlation at later stages of reionization (low redshift). Our results highlight the sensitivity of the cross-power spectrum to the evolving ionized structure of the universe. We compute the auto-angular power spectra C` of the 21 cm brightness temperature, and galaxy distributions, as well as their cross-power spectrum, across multiple redshifts. The cross-power spectrum transitions from positive at higher redshifts (z \u3e 9.5), where neutral hydrogen closely traces the large-scale structure, to negative at lower redshifts (7.5 \u3c z \u3c 8.5), where ionized bubbles surround galaxies and suppress the 21 cm signal. These results demonstrate that 21 cm-galaxy cross-correlations are a powerful tool for understanding reionization and large-scale structure formation. Future observational efforts, including measurements from the Hydrogen Epoch of Reionization Array (HERA) and galaxy surveys from NASA’s Nancy Grace Roman Space Telescope (Roman), will enable direct comparisons with these theoretical predictions, improving constraints on the timing and topology of reionization
