Evaluation Of Receptiveness And Barriers To Including Occupational Therapists On Primary Care Teams, Jacquelyn P. Nash, Sue Dahl-Popolizio, Dayna Maureen Maniccia, Debra Collette Oct 2025

Evaluation Of Receptiveness And Barriers To Including Occupational Therapists On Primary Care Teams, Jacquelyn P. Nash, Sue Dahl-Popolizio, Dayna Maureen Maniccia, Debra Collette

The Open Journal of Occupational Therapy

Background: Although primary care providers (PCP) and occupational therapists recognize occupational therapists can be on the primary care (PC) team to address lifestyle management related to chronic conditions, health literacy, and behavioral health, few occupational therapists work in this setting; PC remains an emerging practice area.

Method: We sought to determine if receptiveness to adding occupational therapists to PC teams has changed. We modified surveys from a 2017 study and added interviews to answer the following questions regarding occupational therapists in PC: (1) What are PCPs' and occupational therapists’ perceptions? (2) What are PCPs' comfort levels in delegating patient appointments …

Limb Regeneration In Damselflies Based On Developmental Stage, Haven O. Clements Oct 2025

Limb Regeneration In Damselflies Based On Developmental Stage, Haven O. Clements

Inquiry: The University of Arkansas Undergraduate Research Journal

Injury is common in wild animals, yet some species possess an adaptive advantage: regeneration. Enallagma vesperum, a species of damselfly, exhibits this regenerative ability, though its persistence and effectiveness across developmental stages remain poorly understood. While previous studies indicate that regeneration ceases following adult emergence, it is unclear whether this ability also diminishes prior to the final larval molt. This study investigated the effectiveness of limb regeneration in E. vesperum across early and late larval instars. I hypothesized that earlier instars would exhibit greater regenerative success due to fewer competing energetic demands compared to later instars, which may prioritize …

Adopting Stuart Hall’S “Race, The Floating Signifier” As A Conceptual Framework Within Aquatic Research And Education, Kurt J. Cordice Oct 2025

Adopting Stuart Hall’S “Race, The Floating Signifier” As A Conceptual Framework Within Aquatic Research And Education, Kurt J. Cordice

International Journal of Aquatic Research and Education

During his 1997 lecture at Goldsmiths College in London, Stuart Hall, renowned for his contributions to sociology and cultural studies, offered his argument that the concept of race functions as a Floating Signifier. In this essay, Stuart Hall’s Race, the Floating Signifier is presented as a strong conceptual framework to support more accurate and effective positioning of race as an important consideration within aquatic research and education. Evidence from a range of disciplines, including historical research, is presented to establish both the importance and challenge of race within aquatic research and education. This evidence is also used to demonstrate …

Treating Low-Concentration Methane Emissions Via A Methanotroph-Based Biotrickling Filter: Techno-Economic And Life Cycle Assessment, Waaseyaaban Landgren, Robert Handler, David Shonnard, Mary E. Lidstrom Oct 2025

Treating Low-Concentration Methane Emissions Via A Methanotroph-Based Biotrickling Filter: Techno-Economic And Life Cycle Assessment, Waaseyaaban Landgren, Robert Handler, David Shonnard, Mary E. Lidstrom

Michigan Tech Publications

Methane, a greenhouse gas which has a global warming potential 80 times greater than carbon dioxide on a 20-year time scale, greatly contributes to global warming. Removing 1 Gt of atmospheric methane by 2050 would limit global temperature increase from reaching 1.5 °C. Currently, biotrickling filter systems for removing atmospheric methane via methanotrophs exist, but not for very low methane concentrations (< 1 v%). Recent work at the University of Washington to isolate and improve a microbial strain which thrives at 500 ppmv CH4 has removed one obstacle in making this technology feasible. In this study, techno-economic and environmental life cycle assessment analyses conducted on this process have assessed its economic feasibility, greenhouse gas reduction potential, and possible areas of improvement. Study results show that at 500 ppmv CH4, this process could remove atmospheric methane at a cost of USD 3992–5224/tCH4. The best-performing case also produces annual net reductions in warming potential by 276–311 tCO2e/120 m3 process unit deployed. Many opportunities exist to improve the outcomes of the baseline analysis even further, especially related to reducing the transport distance of media and harvested biomass.
