Algorithmic management, preferences for autonomy/security and gig-workers' wellbeing: A matter of fit?

The objective of this study was to understand how gig-workers interpret the effects of their laboral activity on their wellbeing. We developed a grounded theory based on interviews with 57 Brazilian gig-workers. The results show that (1) workers and gig-work organizations have preferences for work relationships with more autonomy or security; (2) when there is a congruence of preferences, the worker experiences greater wellbeing, and when the preferences diverge, there are episodes of preference violations that, when repeated, reduce worker wellbeing; and (3) however, not everything is a matter of fit: when both individuals and organizations have the same preference (for example, for more autonomy and less security), worker wellbeing may be vulnerable to abuse, for example, in terms of an unsustainable workload.

Effect of Fiber Supplementation on Systemic Inflammation and Liver Steatosis in Mice Fed with High-Carbohydrate Diets.

High consumption of carbohydrates can trigger metabolic and inflammatory disorders in the body. Thus, the aim of this study was to evaluate the effect of fiber supplementation on inflammation and hepatic steatosis in mice fed high-carbohydrate diets. Swiss male mice were distributed into two control groups and two experimental groups that received isocaloric diet rich in starch (55%) or rich in fructose (55%).
