Taking democracy's temperature: The (in)stability and covariates of populist attitudes

Political Psychology, EarlyView.
Abstract Populism among citizens is often perceived as a problem for democracies due to its rejection of representative practices. In response, scholars have put forward new democratic designs that enhance the democratic system's inclusiveness and popular control, thereby aiming to decrease populism among citizens, or so‐called populist attitudes ...

A Risk Analysis of the Release of Liquid Hydrogen in Road Tunnels: The Effects of Mechanical Ventilation Combined With Geometric and Traffic Characteristics

Risk Analysis, EarlyView.
ABSTRACT The transportation of liquid hydrogen (LH2) via road tankers could prove to be the most cost‐effective short‐term option for long‐distance delivery. However, there are significant risks, particularly in confined spaces like road tunnels. An accidental release of LH2 in these structures is likely to create a flammable hydrogen cloud, the ...

Isometric training at longer muscle–tendon complex lengths: A potential countermeasure to impaired neuro‐muscle–tendon function during space travel

Experimental Physiology, EarlyView.
Abstract Manned space exploration to distant destinations, including Mars, continues to be an aspiration of humankind. Space travel does, however, present many challenges to the body, amongst which adaptation to microgravity is perhaps the largest. For instance, both short and long manned spaceflight missions have shown substantial deleterious effects ...
