According to John Swales, a linguist expert best known for his analysis on communication, a discourse community is a group with a set of common objectives, and utilizes various communicative conventions to achieve those objectives (220). The purpose of this essay is to determine how Rick Nelson successfully affiliates with economic and scientific Discourse communities in his article, Physics and Economics. Swales asserts that a discourse community has six characteristics: it has a common goal, methods of interaction to advance that goal, jargon that is recognizable only to those community members, and experienced members to train novices in order to keep that discourse community active. Thesis: In his article, Rick Nelson successfully affiliates himself with economic and scientific discourse communities because he , outlining a common goal, uses models and statistics to communicate with community members, providing a method of interaction, and suggests that scientists train economists on how to use computer modeling to predict market outcomes, establishing an expert-novice apprenticeship.
