"Gravity" - a new simple negative pressure wound therapy self-build design for low income countries.

Negative Pressure Wound Therapy (NPWT) is prohibitively expensive at the moment and therefore not easily accessible in low-income countries. An additional problem is the requirement of consistent reliable electricity to power the devices. A new low-cost NPWT device was designed from low cost and simple materials and it can be built and operated following a simple set of instructions.

Children's Moral Emotion Attribution in the Happy Victimizer Task: The Role of Response Format.

Previous research in the happy victimizer tradition indicated that preschool and early elementary school children attribute positive emotions to the violator of a moral norm, whereas older children attribute negative (moral) emotions. Cognitive and motivational processes have been suggested to underlie this developmental shift. The current research investigated whether making the happy victimizer task less cognitively demanding by providing children with alternative response formats would increase their attribution of moral emotions and moral motivation.
