Hiding behind the "perfect" mask: a phenomenological study of Filipino university students' lived experiences of perfectionism.

Purpose: Perfectionism is a relevant construct among university students. Researchers have emphasized its significance and even suggested it as an "amplifier of risk" to youth mental health given its association with negative outcomes. The study aims to understand perfectionism and how it is experienced among Filipino perfectionist students from the University of the Philippines Diliman (UPD).

Dispersion control for temporal contrast optimization.

We investigate the temporal contrast of the Light Wave Synthesizer 20 (LWS-20): a powerful, few-cycle source based on the optical parametric synthesizer principle. Saturation effects in the RF amplifier driving the acousto-optic programmable dispersive filter (AOPDF) were found to degrade the coherent contrast for non-monotonic group delay corrections. We subsequently present a new dispersion scheme and design a novel transmission grism-based stretcher optimized for LWS-20.
