Motivated by the need to meaningfully implement the Institute of Medicine's (IOM's) definition of health care disparity, this paper proposes statistical frameworks that lay out explicitly the needed causal assumptions for defining disparity measures. Our key emphasis is that a scientifically defensible disparity measure must take into account the direction of the causal relationship between all...

Algorithms that predict the degree of visual discomfort experienced when viewing stereoscopic 3D (S3D) images usually first execute some form of disparity calculation. Following that, features are extracted on these disparity maps to build discomfort prediction models. These features may include, for example, the maximum disparity, disparity range, disparity energy, and other measures of the di...

Judgments of visual depth rely crucially on the relative binocular disparity between two visual features. While areas of ventral visual cortex contain neurons that signal the relative disparity between spatially adjacent visual features, the same tests in dorsal visual areas yield little evidence for relative disparity selectivity. We investigated the sensitivity of neurons in dorsal visual are...

This article seeks to identify the factors that have impacted the adoption of ISO 10303, the Standard for the Exchange of Product Data (STEP), within the UK Ministry of Defence. The analysis presented in this article is based on Diffusion of Innovation (DOI) Theory and the theory surrounding the Economics of Standards. Using a case study approach, the results indicate that several DOI and econo...

In this paper we describe the most recent work within ISO TC37/SC 4, and in particular the development of a Data Category Registry (DCR) component of the Linguistic Annotation Framework. The DCR will contain a formally defined set of linguistic categories in common use within the language engineering community for reference and use in linguistically annotated resources. We outline the first pro...

We examined in a rabbit model of transient spinal cord ischemia (SCI) whether isoflurane (Iso) preconditioning induces ischemic tolerance to SCI in a dose-response manner, and whether this effect is dependent on mitochondrial adenosine triphosphate-dependent potassium (K(ATP)) channel. Eighty-six rabbits were randomly assigned to 10 groups: Control group (n=8) received no pretreatment. Ischemic...
