Diatom stratigraphy of the lower Pliocene part of the Sisquoc Formation, Harris Grade section, California

Lower Pliocene diatoms were studied from the Sisquoc Formation and lowermost Foxen Mudstone, exposed along Hams Grade north of Lompoc, California, to refine the diatom biostratigraphy of post-Monterey Formation sediments in California. Sixty-seven diatom taxa were identified in the 25 samples examined from the 790-m thick (2950-ft) section. The diatoms are assignable to the uppermost Nitzschia reinholdii Zone and Thalassiosira oestrupii Zone of Damn (1981), and five tentative subzones for local correlation are proposed. Regional correlations and taxon occurrence are discussed, and the base of the Nitzschia reinholdii Zone is redefined as at the last occurrence of Thalassionema schraderi.

Dispelling the Mascot Myth: The Misuse of Indigenous Peoples as Mascots in American Schools

This workshop details the deculturalization process that takes place when Indigenous Peoples are used as mascots in school-related activities; examines the arguments(s) and defensive tactics used by sports fans and school officials to maintain these hegemonic images; and offers successful strategies for developing policy toward the elimination of Indigenous Peoples as mascots.
