A b s t r a c t In this paper, we briefly discuss the dynamic and functional approach to computer symbolic tensor analysis. The ccgrg package for Wolfram Language/Mathematica is used to illustrate this approach. Some examples of applications are attached.

In this article, we propose a fuzzy class relation assigning to each pair of finite fuzzy sets a degree to which they are equipollent, which indicates that they have the same number of elements. The concepts of fuzzy sets and fuzzy classes in the class of all countable sets are introduced, and several standard relations and constructions, such as the fuzzy power set and exponentiation, are defi...

It is the basic tenet of the functional approach to typology that at least some linguistic universals may be explained by appealing to features of language use. But the mechanics of the mapping between function and distribution are seldom made explicit. In this paper, a theory of linguistic adaptation is set out in which universals are treated as phenomena of the third kind in Keller’s (1994) t...

We present a set of problem frames specialized to the area of geographic applications. Problem frames describe the elements of common problems, and help a specifier understand and decompose a complex problem into simpler subproblems for which a solution is often known. We provide an overview of the main issues in geographic applications, and present twelve frames that address many of the proble...

The present article argues for what is essentially a return to the functionalist approach to investigation of memory. Two experiments demonstrate that the effects of level of processing depend on scaled meaningfulness of the material and study time. Data from those experiments along with data currently in the literature are then reanalyzed to examine the effect of repetitions. Of particular int...

Lopes (1996) clearly has limited patience with the Try to work through with undergraduates the equivalence concept of ‘‘rationality’’ as a basis for, or descriptor of, human decision making. I, in contrast, find some of the principles of rationality reasonably compel(x, E; (y, D; z)) B ((x, E; y), D; (x, E; z)), (1) ling—as do subjects when the situation allows them to see the structure of the ...
