A theory of explanation might treat explanations in either a realist or an epistemic (that is, anti-realist) sense. A realist interpretation of explanation holds that the entities or processes an explanation posits actually exist--the explanation is a literal description of external reality.
Officers in pay grades O-1, O-2, and O-3 with more than four years of prior cumulative service in an enlisted or warrant officer grade are paid increased wages using the special pay grades of O-1E, O-2E, and O-3E, respectively.
The most important types of pay structure, or salary structure, are: 1  Graded structures â a sequence of overlapping job grades into which jobs of broadly equivalent size are allocated. Each grade has a range, the maximum of which is usually 20 to 50% above the minimum. Broadband â similar to conventional graded structures, but with far fewer and far wider bands. The maximum of the band can be 100% or more above the minimum. Job Family Structures â Each job family has a different graded structure.
