Students' perceptions of their STEM learning environment.

Australia's economic need for innovation has led to Science, Technology, Engineering and Mathematics (STEM) education becoming an essential investment for the future. This study utilised a mixed-methods approach involving a pre-validated quantitative questionnaire together with qualitative semi-structured focus groups with students across four Year 5 classrooms. Students provided their perceptions of their STEM learning environment and their interactions with their teacher to identify factors influencing their engagement for pursuing these disciplines.

Longitudinal Analysis of Disease Burden in Refractory and Nonrefractory Generalized Myasthenia Gravis in the United States.

Objective: To compare temporal trends in clinical and health care resource utilization (HRU) outcomes in people with refractory and nonrefractory generalized myasthenia gravis (gMG).

Methods: A retrospective analysis of data from adults with gMG in the Myasthenia Gravis Foundation of America Patient Registry. gMG status (ever-refractory or always nonrefractory) and clinical (Myasthenia Gravis-Activities of Daily Living [MG-ADL] scores, exacerbations) and HRU outcomes were determined from questionnaires self-completed 6-monthly for up to 4 years.

Investigation of an Accidental Radiological Release in an Underground Disposal Facility.

A radioactive release took place at the Waste Isolation Pilot Plant near Carlsbad, New Mexico, on 14 February 2014. An alarm from a Continuous Air Monitor caused a switch from unfiltered to filtered air exiting the facility through High-Efficiency Particulate Arrestance filters. The activity measured on the filters demonstrated first order decay, indicating that the release was a single release.
