Unveiling Hidden Prints: Optically stimulated luminescence for latent fingerprint detection
Fluorescent lighting and optical techniques have been widely utilized to enhance the detection of latent fingerprints. However, the development of new techniques is imperative to expand the range of surfaces from which latent fingerprints can be detected. When relying on traditional methods, fingerprint evidence can remain undetected or even disregarded due to insufficient detection and limited detail, especially when dealing with a luminescent background.In this study, we propose the utilization of optically stimulated luminescence (OSL) applied to a Ba2SiO4 matrix, co-doped with Eu2+ and Dy3+, as a powerful method for visualizing latent fingerprints on various surfaces, including thin plastic bags, rigid duct tape, thin aluminum foil, and glass slices. This technique effectively eliminates any luminescent background and significantly enhances optical imaging.This represents the first successful application of OSL in the development of latent fingerprints, thus paving the way for more efficient and effective forensic techniques in the future
Identifying and Addressing Microaggression
This workshop is a culmination of work done by 10 students in Social Work Methods II, who spent the semester working to identify gaps in knowledge and how to address these when understanding and working to educate others about microaggressions. The purpose of the workshop is to help individuals to better be able to define what a microaggression is and allow participants to practice responding to microaggressions. Using and interactive approach this workshop will help people to recognize that dismissive attitudes are harmful. The idea behind this workshop is to help participants engage in self-reflection; to identify times when they may have been microaggressive or the recipient of microaggressiveness.
GOAL/OUTCOME #1 To create awareness surrounding the common occurrences of microaggressions.
GOAL/OUTCOME #2 To help individuals avoid making assumptions and labeling individuals who may make a microaggression
GOAL/OUTCOME #3 To explore the outcomes associated with the experience of microaggressions.
GOAL/OUTCOME #4 To learn ways to respond when someone has been microaggressiv
