In this study, it is aimed to psychometrically evaluate the Preschool Climate Scale (PSCS), which will school climate characteristics of preschool education institutions. Both explanatory and confirmatory factor analyzes were performed in sample teachers administrators (N=910). High internal consistency values obtained from structure consisting 53 items 6 subscales. Similar confirmed at differe...

We present a multi-active-region bipolar-cascade distributed-Bragg reflector (DBR) laser emitting around 910 nm. The three active regions and two tunnel junctions are located in single waveguide core sharing the same third-order vertical mode. A slope efficiency of 2.25 W/A was measured with threshold current density 400 A/cm2. Due to implemented 7th Bragg order surface grating, exhibits narrow...
