 note = {The purpose of this article is to show a perspective that a “theory” is regarded as an actor in practice. Traditionary, a “theory” is a model of practice, independent from practice, and does not affect to practice. It is considered as a tool for describing and understanding practice. This article surveys the MacKenzie's contribution to the study of performativity of a theory to affect practice, and criticizes the distinction of a theory and practice in his perspective. Through analyzing a case study a financial theory, “Value at Risk,” from the viewpoint of scientific sociology to research, I offer the perspective of “Theory as an actor in practice.” The relationship between a theory and practice is not mutually independent. And a theory is not a map of practice, but a part of practice.},
