In a new multidisciplinary study published in the PNAS, a group of researchers from neuroscience and economics at the IMT School of Advanced Studies Lucca links the debated concept of "ego depletion", that is to say the diminution of willpower caused by previous exploitation of it, to physical changes in the areas that govern executive functions in the brain. In particular, the fatigue appears to correspond, in the awake brain, to an increase of the EEG waves typical of sleep in the frontal cortex zone dedicated to making decisions.
Researchers at Peking University have developed ERTool, an open-source Python package that simplifies the application of the Evidential Reasoning (ER) approach for multi-source evidence fusion. ERTool provides a user-friendly interface and high computational efficiency, making it a valuable tool for decision-making in fields like healthcare management, business analytics, and environmental risk assessment.
New research from Colorado State University shows that workplace leaders who are financially stressed are more likely to be abusive toward their subordinates – particularly if the leader is a man. Using data collected through surveys of both leaders and subordinates, the paper shows that financial stress is associated with abusive supervision, and that relationship was stronger for men than women. The paper further explores potential reasoning for that dynamic, including societal gender expectations, and discusses implications from the findings for supporting employees.
