Landfills are a major contributor to methane emissions in the United States. By diverting organic waste from landfills, composting may reduce the global warming effects caused by methane. However, only a small proportion of compostable food is currently composted. This is because of barriers to composting that are both structural (lack of public composting infrastructure) and psychological (insufficient knowledge about and interest in composting among prospective users). We set out to develop a…

Government agencies around the world struggle to retain frontline workers, as high job demands and low job resources contribute to persistently high rates of employee burnout.

In this article, we report on a multicity field experiment (n = 536) aimed at increasing perceived social support and affirming belonging among 911…

The impact measurement shows that calf mortality decreased in the overall target group, although the letters did not produce any measurable outcomes. Why this experiment was conducted: calf rearing necessitates a significant amount of care Failure to ensure appropriate care for animals in dairy farming operations…
