Effects of a culturally sensitive education program on the breast cancer knowledge and beliefs of Hispanic women.

Purpose/objectives: To determine the effectiveness of a multifaceted, culturally sensitive, and linguistically appropriate breast cancer education program for Hispanic women.

Design: Experimental (post-test only, control-group design).

Setting: The parish hall of a Roman Catholic Church in northeastern Arkansas.

Active foundering of a continental arc root beneath the southern Sierra Nevada in California.

Seismic data provide images of crust-mantle interactions during ongoing removal of the dense batholithic root beneath the southern Sierra Nevada mountains in California. The removal appears to have initiated between 10 and 3 Myr ago with a Rayleigh-Taylor-type instability, but with a pronounced asymmetric flow into a mantle downwelling (drip) beneath the adjacent Great Valley. A nearly horizontal shear zone accommodated the detachment of the ultramafic root from its granitoid batholith.

Foundering lithosphere imaged beneath the southern Sierra Nevada, California, USA.

Seismic tomography reveals garnet-rich crust and mantle lithosphere descending into the upper mantle beneath the southeastern Sierra Nevada. The descending lithosphere consists of two layers: an iron-rich eclogite above a magnesium-rich garnet peridotite. These results place descending eclogite above and east of high P wave speed material previously imaged beneath the southern Great Valley, suggesting a previously unsuspected coherence in the lithospheric removal process.
