Medicare Part A (Hospital Insurance) covers skilled nursing care provided in a skilled nursing facility (SNF) under certain conditions for a limited time. Medicare-covered services include, but aren't limited to: 1  Semi-private room (a room you share with other patients). 2  Meals.
The Doctor of Science degree (DSc or ScD) is recognized by the U.S. Dept. of Education as a research doctorate equivalent to the Ph.D. Sometimes, in the U.S., the Doctor of Science is awarded as an honorary degree. Outside the U.S. it is an earned doctorate (as me again states above).
A Ph.D. is often the terminal degree - the highest level of education - that can be achieved in a field of study. For any subject, a Ph.D.-holder is qualified to pursue a career teaching their expertise at the university level. An Ed.D. qualifies its holder to teach, but often takes a more entrepreneurial and technical approach to education.
