Access to Alcohol Use Disorder Treatment Among Women: An Empirical Examination of Health Service Utilization
No full textAdvisor name: Marti DeLiema, PhDAlcohol use disorder (AUD) is a major public health concern for women, yet treatment utilization remains low, and few models adequately explain women’s enrollment in AUD treatment. This study evaluates Andersen’s Behavioral Model of Health Service Use (Andersen’s Model) as a framework for understanding AUD treatment enrollment and tests whether an empirically derived model provides a better fit. Using pooled data from the 2015–2023 National Survey on Drug Use and Health (NSDUH; unweighted n = 28,739, weighted N = 14,382,241), this study examines the influence of Andersen’s Model constructs—predisposing factors, enabling resources, and health needs—on past-year enrollment. Confirmatory factor analysis (CFA) showed poor fit for Andersen’s Model (χ²(147) = 52,408.27, p < .001, CFI = .73, RMSEA = .11). Exploratory factor analysis (EFA) identified five initial factors, but refinement led to a two-factor model: facilitators (e.g., income, education) and barriers (e.g., disability status, mental health status, AUD severity), explaining 70.4% of variance in treatment enrollment. The final model demonstrated excellent fit (χ²(14) = 203.15, p < .001, CFI = .995, RMSEA = .022), outperforming Andersen’s Model. Findings suggest an empirically derived framework better explains women’s AUD treatment access and can inform future research, policy, and interventions to improve treatment engagement.Horgos, Bonnie.

The University of Minnesota Twin Cities Core Curriculum: A revised general education program for all undergraduate students: A report of the Core Curriculum 2025 Committee (version 3)
No full textKathryn Pearson and Will Durfee, co-chairs, Core Curriculum 2025 Committee. A motion to approve the recommendations at the April 3, 2025 Faculty Senate did not pass.A revised general education framework, the “University of Minnesota Twin Cities Core Curriculum,” is proposed as a replacement for the current Liberal Education Requirements that apply to all undergraduate students at the University of Minnesota Twin Cities. The Core Curriculum framework reinforces the value and importance of a liberal education for all students, connects that liberal education to a societally signifi cant focus area that is meaningful to the student and where they examine their focus area through a range of disciplinary lenses, and provides an opportunity for the student to integrate what they have learned in a collaborative project with students from diff erent majors and diff erent colleges.University of Minnesota.

Improving Controller Accuracy: Increasing Localization Accuracy Using Sensor Fusion
No full textAccurate mobile robot localization enables safe and efficient navigation. In this report, the impact of using multiple sensors for localization was studied. Two sensors configurations were tested: IMU and IMU + LiDAR. This was deployed on both a simulated Turtlebot3 and a physical F1TENTH robotic platform, and was tasked to navigate to a goal position using a logMPPI controller. For both the simulation and real-world cases, the effects of using multiple sensors on the controller accuracy were studied. Accuracy was measured by calculating the Euclidean distance between the readings given from the robot versus the ground truth. This was accomplished by tracking the robot model in Gazebo, and using a PhaseSpace system for the physical robot. Using these metrics it was found that in an idealistic environment where sensor noise is minimal, sensor fusion is not the optimal option. However, in real-world scenarios, it was demonstrated that a particle filter fusing IMU and LiDAR readings reduced average localization error by at least 11%. This means real-world robotic platforms should aim to use multiple sensors for localization, to increase accuracy.This research was supported by the Undergraduate Research Opportunities Program (UROP).Chastek, William; Poyrazoglu, Goktug; Cao, Yukang; Isler, Volkan.
