Weisberg	Who is a Modeler?	2007	26	.pdf	application/pdf	10063	705	52	phenomenon in the real world by constructing and then studying a model In the next section, I will contrast modeling with another form of theorizing which I call abstract direct representation (ADR). Modeling involves the indirect theoretical investigation of a real world phenomenon. properties possessed by two real populations of organisms, Volterra's model He engaged in indirect representation of predator-prey phenomena via the constriction of models. In these cases, the model must be similar to the real world phenomenon in Much day-to-day practice of both modeling and ADR involves the mathematical analysis of direct representations. Carroll (1998), Carey and Sundberg (2000), and Lowry and Richardson (1997). theorist will not know how similar the model is to the real world phenomenon real world phenomenon of interest, then the modeler's representation and analysis of the model is also an indirect representation of the real world phenomenon.	./cache/work_57drhskbd5cc7h5r3ylmg56wny.pdf	./txt/work_57drhskbd5cc7h5r3ylmg56wny.txt
