Processes traditionally described as assimilations fall into two main types according to the impact they have on the informational content of speech signals. In grammar-internal assimilation, exemplified by vowel harmony, sound properties that are suprasegmentally extended have a linguistic marking function. In grammar-external assimilation, exemplified by lenition, the extended properties belo...

External network ties between CEOs and directors in major U.S. corporations may limit the e¤ectiveness of internal corporate governance.

Levin and Rappaport (1995, henceforth L&R) argue that the distribution of the English causative alternation is predicted by the internal/external causation distinction. For L&R this distinction is represented in lexical conceptual structure. In this paper I argue that representing this distinction in the syntax, rather than in the lexicon, allows a crosslinguistically more satisfying theory of ...

Chemotaxis, the chemically guided movement of cells, plays an important role in several biological processes including cancer, wound healing, and embryogenesis. Chemotacting cells are able to sense shallow chemical gradients where the concentration of chemoattractant differs by only a few percent from one side of the cell to the other, over a wide range of local concentrations. Exactly what lim...

744 NOTICES OF THE AMS VOLUME 43, NUMBER 7 Introduction Mathematicians tend to think of the notion of symmetry as being virtually synonymous with the theory of groups and their actions, perhaps largely because of the well-known Erlanger program of F. Klein and the related work of S. Lie, which virtually defined geometric structures by their groups of automorphisms. (See, for example, Yaglom’s a...
