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).
The Ed.D. is a practitioner degree focusing on how theory can be applied to solving real world problems. By contrast, the Ph.D. degree is research-oriented with emphasis on testing theories and discovering new knowledge within a narrow discipline. Curricular differences have more to do with substance than rigor.
