    The 13/18 GHz COMSAT Propagation Experiment (CPE) was performed to measure attenuation caused by hydrometeors along slant paths from transmitting terminals on the ground to the ATS-6 satellite. The effectiveness of site diversity in overcoming this impairment was also studied. Problems encountered in assembling a valid data base of rain induced attenuation data for statistical analysis are considered. The procedures used to obtain the various statistics are then outlined. The graphs and tables of statistical data for the 15 dual frequency (13 and 18 GHz) site diversity locations are discussed. Cumulative rain rate statistics for the Fayetteville and Boston sites based on point rainfall data collected are presented along with extrapolations of the attenuation and point rainfall data

    Mindfulness, Democracy, and Education

    In this article, we explain how mindfulness can enhance a democratic way of being, connecting practices of awareness, reflection, dialog, and action to democratic citizenship and social arrangements. We begin by sharing our understanding of democracy as a philosophy and a political system. We then provide a background for the concept of mindfulness as it is used by those in the field of education and health care and as we connect it to democracy and democratic education. We introduce a mindfulness pedagogy and use this pedagogy to develop our concept of mindfully democratic schools. We use the work of John Dewey and Paulo Freire, along with other philosophers of education, to address concerns that mindfulness is fundamentally an apolitical and individual practice rather than a social practice. We end by sharing how mindful practices are imagined and supported within democratic public schools with three vignettes from the Coalition of Essential Schools, whose vision and principles promote teachers’ and students’ mindfully democratic action. In doing this, we describe the types of schools that we see as necessary for our vision of democracy. We invite readers to offer their own stories of mindfully democratic schools

    IDEAS: A Qualitative Inquiry into Project-Based Learning

    As waves of the Global Educational Reform Movement, what Sahlberg (2015) identifies as GERM, still ripple around the world pushing for competition, standardization, the focus on the core subjects, and test-based accountability some schools like IDEAS choose what Hargreaves and Shirley (2012) call The Forth Way towards inspiration and innovation with their project-based learning pedagogy. IDEAS is a small public high school in Sheboygan, Wisconsin and a member of Ted Sizer’s Coalition of Essential Schools (CES). Our qualitative inquiry explores the implications of project-based learning on IDEAS’ students, teachers, academic program and school community. Data came from direct observation, interviews, curriculum documents, and teaching and learning artifacts. Our research informs IDEAS about the impact of their project-based learning pedagogy and validates its significance as part of their curricular program. It demonstrates that democratic principles are at work in some US schools, despite so many instances to the contrary. In the age of GERM this single-case study provides research-based evidence that alternative pedagogical methods and curriculum programs are potentially viable alternatives to many of the curriculum practices commonly found in today’s schools
