Feminine Felons: Violent Offenders' Intersectional Experiences In Twentieth-Century Montana, Cassidy Ann Vander Voort

Graduate Student Theses, Dissertations, & Professional Papers

This paper explores the treatment of violent female offenders in Montana in both the media and prison system from 1900-1960. Women of all races faced gender discrimination from both the carceral system and popular media. Local newspapers sensationalized crimes committed by female offenders, portraying them as women who lived outside of the expectations of womanhood in the twentieth century. Newspapers and courts placed women into two categories: “mad/sad” female offenders, who received forgiveness for their crimes; or unforgivable, “bad” offenders. Crime did not determine these categorizations; instead, gender expectations of the white middle class shaped female criminals’ treatment. If these …

More Than Just A Magic Trick? Exploring An Audience's Supernatural Attributions For Magicians' Performances, Paul J. Silvia, Sara J. Crasson, Gil Greengross, Gustav Kuhn

School of Psychology

Performing magicians have long believed that some audience members attribute their magical effects to supernatural methods—to their use of “real magic”. In two samples of adults (n = 412 and 292), we explored personality traits and broader beliefs that might predict supernatural attributions for performance magic. Supernatural attributions were uncommon—many respondents wholly rejected the possibility that magicians' magic was sometimes real—but nevertheless highly variable. In Study 1, a greater belief that magic tricks at least sometimes involve supernatural powers was associated with relatively higher extraversion, higher neuroticism, and lower openness to experience. In Study 2, random forests suggested that supernatural …

Non-Line-Of-Sight Classification In Urban Areas Based On Machine Learning Algorithms, Mohamed Ali Ezzelarab, Mohamed Abdelazim Mohamed, Eman Abdelhalim, Ashraf Abosekeen

Mansoura Engineering Journal

Non-Line-Of-Sight (NLOS) and multipath errors are significant causes of poor accuracy in Global Navigation Satellite Systems (GNSS). These errors occur when satellite signals are diffracted or reflected by obstacles instead of traveling directly along the Line-Of-Sight (LOS), particularly in urban environments. Such diffracted or reflected signals can reach GNSS receivers, skewing pseudorange measurements and posing challenges to accurate GNSS positioning. This study introduces an innovative approach using supervised Machine Learning (ML) models to detect and mitigate NLOS error.

Predicting Early Hospital Readmissions For Diabetic Patients Using Machine Learning, Amanda Ferraz, Leonardo Oliveira

ICT

This project applies machine learning to predict whether diabetic patients will be readmitted to a hospital within 30 days of discharge. Early readmissions are a costly and critical issue in healthcare, often signalling gaps in post-discharge care and risk management. Diabetic patients face unfair high readmission rates compared to the general population. According to the CDC Diabetes Report Card 37.3 million people in the U.S. or 11.3% of the population had diabetes as of 2019 (CDC, 2021). Our goal here is to develop a binary classification model capable of flagging high risk patient (< 30-day readmission) based on their clinical, demographic, and administrative data. This lets healthcare institutions to take measures,
