Objective: To determine whether narrative text in safety reports contains sufficient information regarding contributing factors and precipitating mechanisms to prioritize occupational back injury prevention strategies. Design, setting, subjects, and main outcome measures: Nine essential data elements were identified in narratives and coded sections of safety reports for each of 94 cases of back...

Previous work from our lab, and elsewhere, has demonstrated that remembered target locations are stored and updated in an eye-fixed reference frame. That is, reach errors systematically vary as a function of gaze direction relative to a remembered target location, not only when the target is viewed in the periphery (Bock, 1986, known as the retinal magnification effect), but also when the targe...

A thorough description of trellis-coded quantization as a nearly-optimal source coding system is presented. Trelliscoded quantizers couple traditional quantization techniques with finite state machines to build effective high dimensional vector quantizers. In a trellis-coded quantizer, each transition of the related finite state machine is labeled, by means of a convolutional code, with one of ...

Coding theoretic approaches have been developed to significantly reduce the communication load in modern distributed computing system. In particular, coded (CDC) introduced by Li et al. can efficiently trade computation resources MapReduce like systems. For more general cascaded CDC, Map computations are repeated at r nodes among tasked with Q Reduce functions s times. this paper, we propose a ...
