GPS geodetic constraints on Caribbean - North America plate motion
We describe a model for Caribbean plate motion based on GPS velocities of four sites in the plate interior and two azimuths of the Swan Islands transform fault. The data are well fit by a single angular velocity, with average misfits approximately equal to the 1.5-3.0 mm yr -• velocity uncertainties. The new model predicts Caribbean-North America motion -65% faster than predicted by NUVEL-1A, a...
متن کاملRegional Survey: M(A)T in North America
We examine two North American case studies, each of which illustrates a different strat-egy for coming to terms with high-volume, highquality translation. The first eschews MT in favour of translation memory technology; the second employs a controlled language to simplify the input to an MT system. Both strategies betray a certain dissatisfaction with the current state of machine translation, a...
متن کاملA Survey of Undergraduate Ornithology Courses in North America
The Committee on Undergraduate Education of the Wilson Ornithological Society conducted a survey of ornithology courses in North America as a service for teachers of ornithology. Our survey of 26 responses uncovered 26 creative approaches to teaching ornithology. Nonetheless, a number of commonalities exist. Courses at small colleges and large universities include both lecture and laboratory co...
متن کاملUpdate on pediatric perfusion practice in North America: 2005 survey.
The devices and techniques used for pediatric cardiopulmonary bypass (CPB) undergo continuous change. New techniques and clinical comparisons of devices are frequently reported in the literature; however, information about the extent to which these techniques and devices are adopted into clinical practice at pediatric heart centers are not well described. We conducted a mail survey of North Ame...
متن کاملCollaborative Research: Seismic and Geodetic Imaging of Subducting Terranes Under North America (S-TUNA)
The collision of thickened crust with subduction zones significantly modifies subduction. These accretion events lead to net growth of continents and drive much of the subduction-related tectonism. Terrane collision may also have a profound effect on the size, coupling, and rupture characteristics of large intraplate earthquakes. The present accretion of exotic terranes with the Alaska subducti...
