Public schools have relied on a deficiency model to structure instruction for minority children that underestimates the funds of knowledge that U.S.‐Mexican households contain. We argue that these funds are not only a key to understanding the cultural systems in which U.S.‐Mexican children emerge, but are also important and useful assets in the classroom.

Tune-out wavelengths measured with an atom interferometer are sensitive to laboratory rotation rates because of the Sagnac effect, vector polarizability, and dispersion compensation. We observed shifts in measured tune-out wavelengths as large as 213 pm with a potassium atom beam interferometer, and we explore how these shifts can be used for an atom interferometer gyroscope.

S ince World War II migration to western states has increased dramatically, in recent years resulting in residential sprawl and creating conflicts between urban and rural populations over land use on millions of acres of public land. The issues are far more complex than public debates and proposed solutions would indicate (see Sheridan 2001). Ultimately, at stake in these conflicts are not just the values and interests of these groups, but how humans can inhabit landscapes and use natural resources sustainably. In this essay we tap political ecology, the science of complexity, and the field of environmental conflict resolution (ECR) to understand the issues around land-use conflicts in Arizona and to frame the problem of sustainability. These approaches may also help us to reintegrate the ecological, economic, and sociopolitical aspects of systems that have
