Community Structure and Media Risk Coverage

Professor Dunwoody regards media organizations to be community creatures; their accounts to be social constructions; and answers to, Who\u27s right? to be relative

Retracts of vertex sets of trees and the almost stability theorem

Let G be a group, let T be an (oriented) G-tree with finite edge stabilizers, and let VT denote the vertex set of T. We show that, for each G-retract V' of the G-set VT, there exists a G-tree whose edge stabilizers are finite and whose vertex set is V'. This fact leads to various new consequences of the almost stability theorem. We also give an example of a group G, a G-tree T and a G-retract V' of VT such that no G-tree has vertex set V'.Comment: 15 pages, 0 figures.

Promises and Challenges of Teaching Statistical Reasoning to Journalism Undergraduates: Twin Surveys of Department Heads, 1997 and 2008

This research is dedicated to the memory of Victor Cohn, former science reporter for the Washington Post and often considered the dean of science writers, who collaborated on the first wave of the survey. The 1997 survey was supported by a grant from the American Statistical Association and the 2008 survey by a grant from the Communication graduate program at Marquette University. Special thanks to research assistants Kathryn Zabriskie and Gongke Li for their valuable help in the survey. The analyses and conclusions are solely those of the authors
