features). Lee and Schachter (1997) suggested that principles of universal grammer or UG (e.g. binding, subjacency) and parameters have different age-related cut-off points for successful triggering and acquisition (however, compare Coppieters, 1987; Birdsong, 1992). Proposals of this type can be united under the label Multiple CPH. In recent years, efforts have turned to isolating precisely wh...

This paper surveys some recent theoretical work in incorporating the dynamics of robot models in motion planning algorithms. Such work is often referred in the literature as kinodynamic motion planning. We rst give an overview of the problem in general and how it diiers from motion planning with pure kinematics. We then describe three model algorithms, each representing one of three broad categ...

We introduce and justify a taxonomy for the structure of markets and minimal institutions which appear in constructing minimally complex trading structures to perform the functions of price formation, settlement and payments. Each structure is presented as a playable strategic market game and is examined for its efficiency, the number of degrees of freedom and the symmetry properties of the str...

BACKGROUND/AIMS Research investigating the relationship between subjective and objective assessment of dysphagia in patients with various diagnoses has yielded conflicting results. The goal of this study is to investigate the reliability of patient self-perceptions of swallowing difficulties compared to expert ratings of videofluorographic studies considering three medical diagnostic categories...

OBJECTIVES The purpose of this study was to evaluate the effect of two-dimensional (2DUS) compared to three-dimensional ultrasound (3DUS) imaging on the maternal-fetal bonding process. METHODS Fifty mothers who had 2DUS and 50 who had 2DUS and 3DUS were included in the study. A postpartum survey by telephone interview was carried out to assess maternal-fetal bonding. Bonding was evaluated by ...

Academic interest in official systems of racial and ethnic classification has grown in recent years, but most research on such census categories has been limited to small case studies or regional surveys. In contrast, this article analyzes a uniquely global data set compiled by the United Nations Statistical Division to survey the approaches to ethnic enumeration taken in 141 countries. The mot...
