There is considerable interest in the biogeochemical cycling of cadmium (Cd) and phosphate (PO4) in surface waters, driven in part by the ongoing development of a paleonutrient proxy that utilizes Cd preserved in fossil planktonic foraminifera to determine past PO4 utilization efficiencies in ocean surface waters. The present article reports...
Benthic chamber measurements of the reactants and products involved with biogenic matter diagenesis (oxygen, ammonium, nitrate, silicate, phosphate, TCO₂, alkalinity) were used to define fluxes of these solutes into and out of the sediments off southern and central California. Onshore to offshore transects indicate many similarities in benthic fluxes between...
The American philosopher and literary critic Kenneth Burke was an "ideologist" (although he never called himself this, and added to that, he spent most of his life avoiding the Marxist term of ideology to describe human "systems" of ideas). Burke instead used the terms "orientation," "rationalization," "perspective." "critical perspective," "way...
SeaWiFS estimates of surface chlorophyll concentrations are reported for the region of the U.S. JGOFS study in the Southern Ocean (∼ 170 °W, 60 °S). Elevated chlorophyll was observed at the Southern Ocean fronts, near the edge of the seasonal ice sheet, and above the Pacific Antarctic Ridge. The elevated...

Work occupies a considerable amount of time in most peoples’ lives and can be a source of great pleasure or a source of pain. To enhance peoples’ experience at work, we must first understand how to measure and improve the design of work. This research sought to do just that,...
This project studied how a user's handedness affects his or her ability to use a
special-purpose handheld digital device such as a digital camera or rangefinder. More
specifically, it sought to identify how handedness affects speed and accuracy when
navigating within a menu system. 24 participants were given 8 menu...
Advancements in the field of medical and computer technology promise a new age of human enhancement technology (HET). These technologies may be aptly applied to existing Assistive Technology (AT), which was created to ameliorate disability, moving one up the spectrum of ability. This study aimed to determine how these technologies...
