Direct observations of X-rays produced by upward positive lightning [PDF]

Scientific Reports
X-rays have been observed in natural downward cloud-to-ground lightning for over 20 years and in rocket-triggered lightning for slightly less. In both cases, this energetic radiation has been detected during the stepped and dart leader phases of downward

Safety Listening in High-Risk Situations: A Qualitative Analysis of Responses to Safety Voice in Aviation. [PDF]

Risk Anal
ABSTRACT Safety listening—responses to voice acts aimed at preventing harm—can avert organizational failures like airplane crashes. Research often focuses on attitudes and perceptions of listening using self‐report measures; consequently, little is known about how safety listening occurs behaviorally and influences safety outcomes in high‐risk ...
