Exact solutions for concentration dependent diffusion and the inverse complementary error function

A direct method of studying the qualitative behavior of concentration dependent diffusion is based on exact solution of problems with diffusion coefficients which are piecewise constant functions of concentration. Polynomial approximations are given for the inverse of the complementary error function. They facilitate the direct method and also Philip's inverse method of studying qualitative behavior.     

Construction of Critically Transformative Education in the Tucson Unified School District

A critically transformative education continues to be at the center of Tucson Unified School District's (TUSD) equity and academic excellence mission. Through the use of the Social Transformation paradigm and the lesson learned from the implementation of the Critically Compassionate Intellectualism Model, TUSD once again created a cutting edge transformative, cultural, ethnic, multicultural, equity-based curricula that seeks to stimulate the blossoming intellectual capacities of our students. It presents the opportunity to build foundations and structures of collective and individual agency. Along the lines of agency, it promotes what is called barriorganic intellectualism and the nurturing of gardens of intellectualism (jardines del intelectualismo) that provide opportunities for both the academic and personal transformation of our students.
