Social norm intervention in real‐world supermarkets in the Netherlands: A quasi‐experimental evaluation of effects on perceived social norms and meat substitute purchases

Applied Psychology: Health and Well-Being, Volume 18, Issue 3, June 2026.
Abstract Social norm perceptions are implicit rules of conduct that describe what is normal and acceptable behavior. Changing social norm perceptions through textual and physical social norm communications can be a promising approach to changing behavior.

Paradox of Value Loops in Dynamic Markets: From Value Post‐(Un)capture to Sustainable Recapture

Business and Society Review, Volume 131, Issue 2, Summer 2026.
ABSTRACT The growing emphasis on sustainability necessitates a re‐evaluation of traditional value creation and capture challenges, highlighting the intricate interrelation between value (un)captured and recaptured. This study investigates the dynamics of overtourism and undertourism in the sustainable development of regions. This prominent incidence of

“Good job reporting this!”: Examining psychological needs and community building in YouTube conspiracy narratives

Political Psychology, Volume 47, Issue 3, June 2026.
Abstract The proliferation of conspiracy theories online has tangible offline consequences, both on an individual and collective level. Conspiracy narratives have been associated with reduced belief in democracy, the rise of populist parties, and can act as a radicalization multiplier in such contexts.

Rational Design of Transition‐Metal Dual‐Atom Catalysts: Exploiting Neighboring Effects for Efficient CO2 Reduction

Carbon Neutralization, Volume 5, Issue 3, May 2026.
A dual‐atom catalyst with adjustable proximity effects is depicted, showing that variations in metal–metal interactions can modulate electronic structure, intermediate adsorption, and reaction pathways. These changes guide product selectivity in CO2 reduction and highlight design principles for efficient, tunable DAC systems.

An autonomous and guided crowd in panic situations

Journal of Computer Science and Technology, 2007
This paper describes a model for simulating crowds in real time. We deal with the hierarchy of the crowd, groups and individuals. The groups are the most complex structure that can be controlled in different degrees of autonomy.
