Profesores queers negociando geografías de seguridad en los años noventa

This study demonstrates how three queer teachers in conservative spaces created geographies of safety during the 1990s. Each of the three teachers discussed initiated a geography of safety, and these histories are relevant to the ongoing negotiation that queer elementary and secondary educators today engage as they reconcile their moral authority as teachers with their gender(s) and sexualities.Este estudio demuestra cómo tres profesores queers  en espacios conservadores crearon geografías de seguridad durante la década de los noventa.

Influence of different palladium precursors on the properties of solution-combustion-synthesized palladium/ceria catalysts for methane combustion

A series of Pd/CeO2 catalysts was prepared by solution combustion synthesis (SCS) using different Pd precursors. The powders were characterized by complementary techniques such as BET surface area measurements, X-Ray diffraction analysis, X-Ray photoelectron spectroscopy, temperature-programmed reduction, temperature-programmed oxidation, and high-resolution TEM. The results obtained evidenced the formation of a Pd-Ce solid solution on all SCS samples. This solid solution is in the form of an ordered supercell structure only in the SCS catalyst prepared from palladium nitrate. This was correlated to the heat of reaction between Pd(NO3)(2) and the fuel. The samples were tested for methane catalytic combustion, and the reaction rates on all SCS samples were approximately twice that of the impregnated counterpart, irrespective of the precursor. This was attributed to the presence of the Pd-O-Ce solid solution, which gave rise to strong Pd-ceria interactions.Postprint (author's final draft

LGB TEACHER ORGANIZATIONS FROM 1970-1985

This dissertation examines the activities and organization of six LGB teachers’ organizations which were active between 1970 and 1985. LGB teachers’ organizations located in California, New York City, the American Federation of Teachers, and the National Education Association are each examined in respective chapters. Each of these chapters focuses on a specific theme that is apparent throughout the histories of these groups. These themes include: professionalism, community, negotiation, and the portrayal of LGB teachers. This dissertation is an inquiry into the first time in American history when LGB people who were K-12 teachers came out in large numbers, the first time they were seen as being not heterosexual without being forced out of America’s schools, and the first time these teachers acted in groups to protect themselves and LGB students from an educational system that was openly hostile to anyone who did not appear to be heterosexual. LGB teachers were among the first LGB people to organize professional groups and they were among the first LGB people to secure commitments against discrimination from national level labor unions. Working first to protect their employment rights and later to ensure the educational rights of LGBT students, LGB teachers’ groups were at the forefront of shifting American schools toward greater inclusivity. By examining these groups through the perspectives of education, labor, and LGBT history this dissertation will argue that the relevance of these LGB teachers’ groups extends far beyond the individual experiences of LGB teachers and their schools and can be used to discuss broad expectations that Americans held, and continue to hold, for their schools and teachers
