“Any Time, Any Place, Any Path, Any Pace:” A Curricular Design for the Teaching of Languages for Specific Purposes in the Pandemic Era and Beyond

As US universities face unprecedented financial challenges due to the Covid-19 pandemic, university officials have begun reducing and even eliminating foreign language programs. NYU marketing professor Scott Galloway is even predicting the demise of dozens of US colleges and universities as they depend almost exclusively on tuition (Galloway, 2020). Public health officials question whether pre-pandemic educational conditions will resume even after the end of the pandemic. Costly safety measures at schools and universities will have to be implemented. To safeguard the teaching of LSP courses, this essay proposes the adoption of a Center for LSP Studies, preferably anchored at a current U.S. Department of Education Title VI CIBER (Center for International Business Education and Research) or at a dynamic World Languages Department. Our recommendation is for LSP courses to be taught using a self-paced, mastery-based model of instruction designed for use during the pandemic and beyond. The model is based on two programs in operation, one at The Ohio State University’s Individualized Foreign Language Program (established in 1978), and the other at The Florida Virtual School (established in 1997). Specifically, students throughout the US would start and finish any one of a slate of online LSP courses at any time during the school year at a pace that best suits their needs. The Center would hire experts to design and manage the courses while students nationwide would pay tuition to the providing institution

A new argument against cooling by convective air eddies formed above sunlit zebra stripes

There is a long-lasting debate about the possible functions of zebra stripes. According to one hypothesis, periodical convective air eddies form over sunlit zebra stripes which cool the body. However, the formation of such eddies has not been experimentally studied. Using schlieren imaging in the laboratory, we found: downwelling air streams do not form above the white stripes of light-heated smooth or hairy striped surfaces. The influence of stripes on the air stream formation (facilitating upwelling streams and hindering horizontal stream drift) is negligible higher than 1-2 cm above the surface. In calm weather, upwelling air streams might form above sunlit zebra stripes, however they are blown off by the weakest wind, or even by the slowest movement of the zebra. These results forcefully contradict the thermoregulation hypothesis involving air eddies
