descriptive theory tells us the ways things are, but not what we ought to do
Descriptive theories are theories that explain how international business (or for that matter any other business) took place in the past and how it is related to the present.
system theory is related to the process of production , contingency theory is the theory of minimize the problems of organization
it is called the labeling theory
Social Contract theory
philosophical theory of eternity
Plate tectonics Theory

Explanatory theory in psychology is based on it's research methodology. They are also called descriptive theories. An explanatory theory attempts to explain a phenomenon in terms of established theories in a field, in this case, psychology.
A substantive theory may be constructed within the process of identifying differences and similarities of contextualized instances, and patterns, across and within case studies focused on a similar theme. The content of substantive theory is mainly descriptive, focused on the essence, or substance, of the numerous case instances in a parsimonious relational structure.
Translation theory is considered, most of the times, as a descriptive discipline which tries to define the mental processes involved in the act of translating, like decoding, deverbalising etc. Coseriu considers translation theory to be just a sub-field of language theory. Translation theory is rarely a normative discipline. For this reason, most translators tend to consider it as being of little use for their profession.

Activity Theory is a framework or descriptive tool for a system. People are socio-culturally embedded actors (not processors or system components). There exists a hierarchical analysis of motivated human action (levels of activity analysis).
The new perfect unity system theory is about natural perfect state of a natural body. It solved and explained major problems in physical science and our natural world called universe. Albert Einstein explain it but unable proof it, in which he tagged it "UNIFIED FIELD THEORY" .This theory will surely put end to major problems in mathematical physics, astrophysics, geophysics, science and technology general area as quantum theory, relativity theory, quantum mechanics, equation of emotions, gravitational field theory, potential theory, atomic theory, wave equation, thermodynamics and so on, if only we can intensify our research further. It focus to solve1) Combination of general relativity theory and quantum theory into a single theory that can claim to be the complete theory of nature.2) Unification of particles and forces which determine that various particles and forces can be unified in a theory that explain them all as manifestations of a single fundamental entity.3) The problem of cosmological mysteries that explain the constants of the standard model of cosmology.
