Reactions to perceived broken promises lead to workplace stress for police officers

A study by the University of Birmingham found that police officers experience stress and anxiety when they perceive a violation of their psychological contract, leading to feelings of anger and frustration. The researchers also discovered that fairness and self-efficacy play a crucial role in mediating this relationship.

Women and men executives have differing perceptions of healthcare workplaces according to a survey report in the Journal of Healthcare Management

A survey report in the Journal of Healthcare Management finds that women executives are less likely to see employers as gender-neutral in hiring and promotion. The results show little improvement in these outcomes since 1990, highlighting a persistent gap between men's and women's perceptions of healthcare workplaces.

Advancing multiprincipal alloys

Researchers have developed a way to predict the properties of multiprincipal element alloys (MPEAs), which exhibit unique combinations of strength, ductility, and damage tolerance. The team used electron microscopy and atomistic simulations to unveil the mechanistic origins of desirable properties in MPEAs.

Deep learning gives drug design a boost

A new computational tool, Metabolite Translator, uses deep learning to predict metabolites in the human body, providing a broader understanding of how drugs interact with enzymes. The method has been shown to perform as well as existing rule-based methods and identified novel enzymes involved in drug metabolism.

Exposure to vitamin D in the womb might minimize risk of high blood pressure for children born to mothers with preeclampsia

A study found that higher vitamin D levels in pregnancy may protect against childhood high blood pressure, particularly for children born to mothers with preeclampsia. The analysis of data on 754 mother-child pairs revealed a dose-related association between cord-blood vitamin D levels and reduced offspring blood pressure.
