Learning To Teach In Place: Transforming Pre-Service Teacher Perceptions Of Science Teaching Through Place Pedagogies, Hongming Ma, Monica M. Green

Australian Journal of Teacher Education

Although teaching science outdoors is well established in global circles, its pedagogical value in Australia is less understood. This paper addresses this gap through its investigation of outdoor science teaching in a science method course in a teacher education program at an Australian regional university. As part of their coursework, pre-service teachers designed and delivered science lessons to primary school-aged children in small teaching groups in a wetland setting and wrote reflective essays about the experience. Data collection methods included document analysis of the essays as well as follow-up semi-structured interviews with pre-service teachers. Findings suggest that the outdoor science …

"We Can't Breathe." Like George Floyd, Black Families In New York City Have A Knee On Their Necks, Shanée Brown

Scholarly Works

While watching the murder of George Floyd, one thing should have remained imprinted in everyone's mind: he was a father. This racist officer permanently separated a father from his children when he recklessly, yet intentionally placed his knee on Mr. Floyd's neck for eight minutes and forty-six seconds. When the Administration for Children's Services ("ACS") removes Black children from their homes for unjust reasons, it places its knee on the necks of Black families.

Breathing as a family involves parents and children inhaling and exhaling the love shown to each other. To separate a family means to obstruct that family's …

Diagnosis Of Early Delayed Graft Function (Dgf) Using Timp-2*Igfpb-7 Product In Transplant Recipients: Preliminary Results, Russell Leong, Cassandra Rodd, Kellyann M. Gomes, Solomiia Savedchuk, Paul S. Kellerman

Conference Presentation Abstracts

Background: DGF is acute kidney injury (AKI) defined as need for dialysis within one week of renal transplant. AKI is defined by a change in serum creatinine (SCr), however early recognition is limited by delay in creatinine rise. Accurate early biomarkers may lead to prevention or treatment of established AKI. The product of two novel biomarkers of cell cycle arrest, tissue Inhibitor of metalloproteinase-2 (TIMP-2) and insulin-like growth factor binding protein (IGFBP-7) have shown promise in predicting AKI. In prior studies, TIMP-2*IGFPB-7 ≤0.3 had high negative predictive value, and ≥2 high positive predictive value for AKI. Aims - 1) Investigate …

Programmed To Protect And Serve: The Dawn Of Drones And Robots In Law Enforcement, Nanci K. Carr

Journal of Air Law and Commerce

No longer does the field of law enforcement rely solely on human cognition and capability as drones have become first responders, responding to emergency calls with a drone rather than a human officer. Drone technology can transform police work, just as it has package delivery and military strategy. These drone officers allow for higher law enforcement efficiency, safer communities, and even saved lives. However, they also raise civil liberty concerns given that the drones have the power to track vehicles and people without consent, and they can collect and store video records of everyday life, reducing expectations of privacy. This …

Performance Analysis Of Iot-Based Healthcare Heterogeneous Delay-Sensitive Multi-Server Priority Queuing System, Barbara Kabwiga Asingwire, Alexander Ngenzi, Louis Sibomana, Charles Kabiri

All Rsif Scholars' Publications

Previous studies have considered scheduling schemes for Internet of Things (IoT)-based healthcare systems like First Come First Served (FCFS), and Shortest Job First (SJF). However, these scheduling schemes have limitations that range from large requests starving short requests, process starvation that results in long time to complete if short processes are continuously added, and performing poorly under overloaded conditions. To address the mentioned challenges, this paper proposes an analytical model of a prioritized scheme that provides service differentiation in terms of delay sensitive packets receiving service before delay tolerant packets and also in terms of packet size with the short …
