Types of Grass to Grow in Central Alabama. Plant warm-season grasses in central Alabama for best results in sun or partial shade. Cool-season grasses like Kentucky bluegrass, ryegrass and fine fescue do most of their growing from fall to spring, and prefer cooler temperatures. Prepare the planting site well ahead of spring planting.
Operational Definitions. To test an idea, one must gather data. This means one must relate ideas to concrete, measurable events in the world. That is why scientists need operational definitions, which are definitions that tell how to measure or detect something.
The operational definition of an empirical term (i.e., a descriptor of some element of physical experience) is the description of a specific process, or set of validation tests, accessible to more persons than the definer (i.e., said to be publicly accessible), whereby it is (or can be) repeatedly measured or tested.herefore, weight of an object labels an operational definition which is a nonspecific process.) But an historical event (e.g., the process of taking my weight last Tuesday) cannot be an operational definition because it cannot be repeated.
