The purpose of this investigation was to compare the effectiveness of integrated and segregated settings in elementary physical education. The efficacy of each setting was measured by the quantity of opportunities to respond (OTR) and the quality of those responses. This study examined the frequency and motor appropriateness of OTRs...
Scholars are ushering autobiographical writing of all kinds into the world of literary and scholarly writing: in course titles and syllabi, in academic journals and on bookshelves, autobiographical writing is flourishing. People's real stories offer insights into how people really live and view this life. They offer perspectives which necessarily...
After the April 2010 explosion on the Deepwater Horizon oil rig, and subsequent release of millions of barrels of oil, two Corexit oil dispersant formulations were used in unprecedented quantities both on the surface and sub-surface of the Gulf of Mexico. Although the dispersant formulations contain four classes of surfactants,...

During the Deepwater Horizon oil well blowout in the Gulf of Mexico, the application of 7 million liters of chemical dispersants aimed to stimulate microbial crude oil degradation by increasing the bioavailability of oil compounds. However, the effects of dispersants on oil biodegradation rates are debated. In laboratory experiments, we...
