A Multi-State Look Into Early Intervention Speech-Language Pathologists’ Confidence Identifying And Diagnosing Autism, Allison Gladfelter, Adelaide Parr, Anna Cannone, Sarah O'Connor

CISLL Publications

Purpose: Although autism can be reliably diagnosed by 18 months of age, long wait times and limited access to qualified providers prevent families from obtaining timely diagnostic services. Trained speech-language pathologists (SLPs) are qualified to diagnose autism, ideally as part of a multidisciplinary team. SLPs working on early intervention (EI) teams are well-situated to help close this diagnostic wait time gap. The purpose of this survey study was to explore EI SLPs’ experiences serving autistic children, confidence in identifying and diagnosing autism, and their perceptions of barriers or facilitators to diagnostic confidence and wait times.

Framing The Pressure: Mental Health Representation In Olympic Athletes Through The Weight Of Gold, Daniel B. Gearin

USF Tampa Graduate Theses and Dissertations

This study examines how the HBO documentary The Weight of Gold constructs meaning around athlete mental health through narrative and visual framing. Grounded in framing theory, the purpose of this research is to identify the key themes presented in the film and analyze how cinematic techniques shape audience understanding of mental health in Olympic athletes. The rationale for this study stems from a gap in existing research, as most scholarship focuses on psychological outcomes rather than how media representations construct those meanings. Using a qualitative approach, the study applies thematic analysis to 17 scenes of the documentary, supported by a …

Analysis Of Prestressed Concrete Beams Experimentally Utilizing Steel Strands And Cfrp Bars, Ahmed Edan, Wael Abdulsahib

Engineering and Technology Journal

This research seeks to improve the performance behavior of reinforced concrete (RC) beams by examining their load-deflection diagrams using ordinary and prestressed carbon fiber-reinforced polymer (CFRP) bars in place of standard steel reinforcement instead. Using CFRP bars as prestressed tendons to replace the bottom steel rebars, eight 1800-mm long RC beams with a 200 mm×300 mm cross-section were evaluated and split into three groups, evaluating critical loading phases (i.e., cracked, ultimate, and mid-span deflection). Relative to the reference beam, beams reinforced with CFRP had far higher load-carrying capacities and ductility. One beam, reinforced with regular CFRP bars, exhibited a mid-span …
