In this study, we explore leadership practices in a dual-language elementary school led by three leaders of color committed to the ideals of cultural responsiveness. We employ an organizational leadership lens informed by aspects of culturally responsive school leadership (CRSL) and teaching (CRT) to interpret interview and observational data collected during the implementation of an equity-oriented engineering program for English learner (EL) students. In the midst of attempting to implement this school-research partnership, pre-existing tensions between the school’s leadership and instructional culture rose to the forefront, offering the opportunity to analyze the data with this particular intersectional lens (organizational leadership and CRSL). Thus, subsequent data analysis focused not on program implementation but rather the existing challenges present in the school. Insights from our data suggest that both school leaders and teachers faced considerable challenges that appeared to stem from disparate understandings of how to achieve equity for their EL students. Ultimately, these challenges prevented leaders’ successful enactment of CRSL within the existing organizational infrastructure. We suggest that the lack of explicit processes of critical consciousness defined the school culture and that accountability practices limited leaders’ ability to implement CRSL. 

Nonlinear refractive index, n2 , values as high as 1±.1x10 -9 cm 2 /W were measured in atomic layer deposition (ALD) grown TiO 2 nanoscale films, using femtosecond thermally managed Z-scan. The several order of magnitude increase in n 2 is believed due to the incorporation of nitrogen during growth. 

We detect the generation of enhancer-free singlet oxygen in distilled water and heavy water upon illumination with 405-nm laser radiation by measuring the quenching of the uric acid spectral peak at 294 nm.
