VAGUE PARTS AND VAGUE IDENTITY

We discuss arguments against the thesis that the world itself can be vague. The first section of the paper distinguishes dialectically effective from ineffective arguments against metaphysical vagueness. The second section constructs an argument against metaphysical vagueness that promises to be of the dialectically effective sort: an argument against objects with vague parts. Firstly, cases of vague parthood commit one to cases of vague identity. But we argue that Evans' famous argument against will not on its own enable one to complete the reductio in the present context. We provide a metaphysical premise that would complete the reductio, but note that it seems deniable. We conclude by drawing general morals from our case study.     

Communicating to Farmers About Skin Cancer The Behavior Adaptation Model

Although health campaigns promote avoidance of behaviors that put an individual's health at risk, often these behaviors cannot be avoided, and campaign messages designed to encourage behavior adaptation afford greater likelihood of success. With that in mind, a model of health risk behavior adaptation was proposed and tested using four different behaviors in a communication campaign aimed at reducing farmers' risk for skin cancer, farmers and farm wives answered a series of questions about their skin cancer prevention and detection behaviors and attitudes. Interpersonal expectancies, social resources, and actual procedural knowledge predicted perceived procedural knowledge and public commitment, which, in turn, predicted behavior adaptation.
