The primary focus of this work is on examining structure-property relationships of interest for high-power nonlinear optical and laser crystals. An intuitive and simply illustrated method for assessing the nonlinear optical potential of structurally characterized noncentrosymmetric materials is introduced. This method is applied to materials including common quartz and tourmaline...
The purpose of this qualitative research study was to describe the experiences of secondary teachers who were actively involved in positions of teacher leadership in their schools and to discover the meaning that leadership activities had for them in their work.
