European Journal of Philosophy, EarlyView.Abstract An oft‐overlooked aspect of Sartre’s concept of selfhood is his rejection of good faith and sincerity as normative ideals. We argue that Sartre’s paradoxical treatment of good faith – claiming both that it is a manifestation of bad faith and the antithesis of it – holds a key to understanding Sartre’s account of selfhood.

Considerations for the Design of Sinusoidal Slug Testing Methods
Groundwater, EarlyView.Periodic hydraulic tests estimate aquifer properties using controlled groundwater‐level oscillations. Evaluating two sinusoidal slug‐test designs shows large motion errors when transfer‐link and flywheel ratios are high or variable. Rotating‐drive mechanisms are therefore suboptimal; stepper‐motor winches generate more accurate sinusoidal motion ...
