1 I N T R O D U C T I O N The work described here is in the context of developing a system that will correct the written EnliSh of native users of American Sign Language SL) who are learning English as a second language. In this paper we focus on one error class that we have found to be particularly prevalent: the illegal omission of NP's. Our previous analysis of the written English of ASL nat...

CD44, MT1-MMP, and MMP9 are implicated in the migration of osteoclast and bone resorption. This study was designed to determine the functional relationship between CD44 and MT1-MMP in the activation of pro-MMP9. We used osteoclasts isolated from wild-type and CD44-null mice. Results showed that MT1-MMP is present in multiple forms with a molecular mass ~63, 55, and 45 kDa in the membrane of wil...

This paper addresses the question of whether and how the semantics of third-person pronouns can vary across languages. I investigate third-person non-demonstrative pronouns in St’át’imcets (Lillooet Salish), including null pro and its overt animate plural counterpart wit. I provide evidence for a striking cross-linguistic difference between the St’át’imcets pronouns and English ones: third-pers...

Long-distance dependencies have long been at the center of linguists’ attention, and have played an important role in the ongoing dialogue between theoreticians and experimentalists, who share an interest in the motivation for empty categories and in the nature of filler-gap relationships. In this paper, we address certain issues that arise with regard to Korean relative clauses from both a the...

The intimate relation between general theoretical hypotheses and the empirical data which can support them is the central topic of the discussion. Data from different modes of acquisition are reviewed in the light of their general theoretical significance as different kinds of evidence for linguistic theory. Traditionally assumed correlations of properties related to the setting of the null sub...

This paper sketches a particular aspect of the active/passive distinction and tries to attribute all syntactic properties of these modes to the behavior of a single functional projection. The paper is organized in two parts. Part I is devoted to a discussion of the voice distinction in Toba Batak. It is argued that a correct syntactic description of the data involves movement of the subject in ...
