概要	Team psychological safety is the shared belief among members of a team that the team is safe for interpersonal risk-taking — that one can speak up, ask questions, admit mistakes, and propose ideas without fear of being embarrassed, rejected, or punished. Amy Edmondson introduced and measured the construct in her 1999 Administrative Science Quarterly study of work teams in a manufacturing company, showing that it is a property of the team, not just the individual, and that it enables team learning behavior. Her measurement approach treats psychological safety as a latent belief captured by self-report items, aggregated to the team level once within-team agreement justifies it. The pivotal finding was that psychological safety predicts learning behavior, which in turn mediates the relationship between safety and team performance. The construct has since become central to research and practice on teams, learning, and high-reliability work.	The Job Demands-Resources (JD-R) model is a flexible framework in organizational behavior and occupational health psychology that explains employee well-being and performance through two parallel processes. Introduced by Demerouti, Bakker, Nachreiner, and Schaufeli in 2001 and elaborated by Bakker and Demerouti in 2007, it holds that every job can be described by demands — aspects requiring sustained effort — and resources — aspects that help achieve goals, reduce demands, or stimulate growth. A health-impairment process runs from chronic demands to exhaustion and strain, while a motivational process runs from resources to work engagement and positive outcomes. The two paths interact: resources buffer the impact of demands on strain, and demands can amplify the motivating power of resources. Unlike fixed lists of job features, the JD-R model is deliberately open, letting researchers slot in whatever demands and resources matter in a given occupation.
