Washing your hands regularly with soap and water is an effective and easy way of reducing the risk of people falling ill with COVID-19, influenzas or a cold, or contracting other viral illnesses. Stickers and posters were developed focusing on reframing, nudging and habit stacking. Displaying the posters in the office environment led to an increase in handwashing amongst employees. Soap consumption went up. Why this experiment was conducted: improved hygiene standards in the workplace is the…

Among the many structural reasons for low savings rates (inaccessible banks, high transaction costs, distrust of financial institutions, lack of financial literacy), psychological barriers such as impatience or lack of self-control may also play a role. Additionally,…

Despite the overwhelming medical evidence on the protection offered by the second, third and fourth doses of the Covid-19 vaccine, the acceptance of these doses remains low despite the existing supply. The problem is likely because there are currently no reminders in the province of Chaco, Argentina. This makes it difficult for residents to know if they are eligible for the next dose of the COVID-19 vaccine and where to access it. Booster vaccination is associated with a lower risk of mortality…

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…
