This paper describes a model of politeness between intentional agents developed from sociolinguistic observations of human-human interactions (Brown and Levinson, 1987) and suggests a method for applying it to human-machine interactions. Applications in the context of a medication reminder system are presented including data which suggest that the Brown and(More)
A central source of cultural differences, with powerful impacts on perception and behavior, is communication of " politeness " and its role power and familiarity relationships, urgency , indebtedness, etc. We are operationalizing and making computational a culturally abstract and universal theory of human politeness which combines culture-specific aspects(More)
PURPOSE Retinal prosthetic devices that use microelectrode arrays to stimulate retinal nerve cells may provide a viable treatment for degenerative retinal diseases. Current devices are based on electrical field-effect stimulation of remaining functional neural elements. However, the distance between target neurons and electrodes limits the potential density(More)
We have been working on home automation to support eldercare. This is an instance of long term human-automation interaction in very intimate and personal settings with a potentially difficult user population. We report our design philosophy and some of the lessons learned relative to that philosophy from a six month field test with representatives of this(More)
Long duration space flights such as a two and a half year mission to Mars present many unique challenges to the behavioral health of astronauts. Factors such as social monotony, workload, a confined environment, sensory deprivation, and limited access to family and psychosocial support can affect crew welfare and task performance. NASA recognizes a "risk of(More)
A significant and prevalent aspect of human behavior (as opposed to attitudes and beliefs) which is affected by cultural differences is communication style.

While proficiency in a language is important, it is only one aspect of effective communication. Knowledge about culturally influenced social norms, or etiquette, directly(More)
INTRODUCTION Our objectives were to examine mononuclear cell gene expression profiles in patients with systemic lupus erythematosus (SLE) and healthy controls and to compare subsets with and without atherosclerosis to determine which genes' expression is related to atherosclerosis in SLE. METHODS Monocytes were obtained from 20 patients with SLE and 16(More)
