The appearance of New Media Reader is a milestone in the history a new field that, just a few years ago, was somewhat of a cultural underground. Before taking up the theoretical challenge of defining what new media actually is, as well as discussing the particular contributions this reader makes to answering this question, I would like very briefly to sketch the history of the field for the ben...

Foreign language learners typically experience considerable anxiety about taking listening tests. This study investigated how four forms of listening support (pre-teaching of content and vocabulary, question preview, and repeated input) affect the anxiety levels of college students in Taiwan taking a multiple-choice achievement test, which counts for their final grade in a required listening co...

Restricted Sumsets and a Conjecture of Lev

Let A, B, S be finite subsets of an abelian group G. Suppose that the restricted sumset C = {a + b: a ∈ A, b ∈ B, and a − b 6∈ S} is nonempty and some c ∈ C can be written as a + b with a ∈ A and b ∈ B in at most m ways. We show that if G is torsion-free or elementary abelian then |C| > |A| + |B| − |S| − m. We also prove that |C| > |A| + |B| − 2|S| − m if the torsion subgroup of G is cyclic. In...
