Aging Increases Prosocial Motivation for Effort.
Patricia L Lockwood, Ayat Abdurahman, Anthony S Gabay, Daniel Drew, Marin Tamm, Masud Husain, Matthew AJ Apps
May 20, 2021
Social cohesion relies on prosociality in increasingly aging populations. Helping other people requires effort, yet how willing people are to exert effort to benefit themselves and others, and whether such behaviors shift across...
Developing Computational Thinking Teaching Strategies to Model Pandemics and Containment Measures.
COVID-19 has been extremely difficult to control. The lack of understanding of key aspects of pandemics has affected virus transmission. On the other hand, there is a demand to incorporate computational thinking (CT) in the...
Plaque Structural Stress
Atherosclerosis remains a major cause of death worldwide, with most myocardial infarctions being due to rupture or erosion of coronary plaques. Although several imaging modalities can identify features that confer risk, major...
