Stellar feedback and triggered star formation in the prototypical bubble RCW 120.

Radiative and mechanical feedback of massive stars regulates star formation and galaxy evolution. Positive feedback triggers the creation of new stars by collecting dense shells of gas, while negative feedback disrupts star formation by shredding molecular clouds. Although key to understanding star formation, their relative importance is unknown.

Randomized comparison of group cognitive behaviour therapy and group psychoeducation in acute patients with schizophrenia: effects on subjective quality of life.

Objective: Although the clinical efficacy of cognitive behaviour therapy (CBT) has been established for patients with schizophrenia, the data on effects on quality of life (QoL) are lacking. The purpose of the present study was therefore to compare the effects of a brief group CBT and a group psychoeducational (PE) programme in patients with schizophrenia on QoL.

Method: A total of 88 inpatients with schizophrenia were randomized to receive a therapy envelope of 8 weeks including either 16 sessions of group CBT or eight sessions of group PE treatment.
