Observational adequacy. The theory achieves an exhaustive and discrete enumeration of the data points. There is a pigeonhole for each observation. Descriptive adequacy. The theory formally specifies rules accounting for all observed arrangements of the data. The rules produce all and only the well-formed constructs (relations) of the protocol ...
Chomsky defines three levels of success for any linguistic theory. These are "observational adequacy" (i.e. correctly picking out the valid linguistic data that linguists must work on), "descriptive adequacy" (i.e. assigning clear structural description to elements of sentences) and "explanatory adequacy" (i.e. justifying, with the help of a principled basis, the selection of a descriptive ...
A theory of change (ToC) is an explicit theory of how and why it is thought that a social policy or program activities lead to outcomes and impacts. [1] ToCs are used in the design of programs and program evaluation, across a range of policy areas. Theories of change can be developed at any stage of a program, depending on the intended use.
Theory-driven evaluation (also theory-based evaluation) is an umbrella term for any approach to program evaluation that develops a theory of change and uses it to design, implement, analyze, and interpret findings from an evaluation. [1] [2] [3] More specifically, an evaluation is theory-driven if it: [4]
Finally, grammars and metagrammars are ranked by three levels of adequacy: observational, descriptive, and explanatory. A core aspect of the original Standard Theory is a distinction between two different representations of a sentence, called deep structure and surface structure. The two representations are linked to each other by a set of ...
Since then, other theories have emerged as well as attempts at contrasting and synthesizing them. As a result, a number of typologies of group change theories have been proposed. A typology advanced by George Smith (2001) based on the work of Mennecke and his colleagues (1992) classifies theories based on whether they perceive change to occur ...
Most claims about the dangers of seed oils tend to focus at least in part on inflammation — more specifically, that seed oils contain large amounts of omega-6s relative to omega-3s.
In the philosophy of science, observations are said to be "theory-laden" when they are affected by the theoretical presuppositions held by the investigator. The thesis of theory-ladenness is most strongly associated with the late 1950s and early 1960s work of Norwood Russell Hanson, Thomas Kuhn, and Paul Feyerabend, and was probably first put forth (at least implicitly) by Pierre Duhem about ...
