Mineworkers' Perspectives on Whole‐Body Vibration Exposures in the Ghanaian Mining Industry

Safety Science and Technology, EarlyView.
ABSTRACT Across most industries, there appears to be greater commitment to occupational safety than to occupational health, largely because safety effects are readily observable, whereas health effects are hard to notice, as they take prolonged exposure to become apparent.

A War of Words: Framing the Austrian Civil War through the Language of the Combatants

History, EarlyView.
Abstract The Austrian civil war was a four‐day conflict in 1934 between the largest left‐wing paramilitary, the Schutzbund, and government forces aligned with the largest right‐wing paramilitary group, the Heimwehr. The Schutzbund was quickly and brutally suppressed through the use of overwhelming force, armoured vehicles and even artillery deployment ...

Taking Different Roads to Rome: Protective and Proactive Orientations Towards Institutional Power Resources

British Journal of Industrial Relations, EarlyView.
ABSTRACT Works councils in Germany possess substantial institutional resources to protect workers' interests. Yet little is known about how these resources are mobilised in practice and why similar outcomes may emerge through different pathways. Drawing on two German firms acquired by Chinese state‐owned enterprises, this study examines how works ...
