This study examined passages containing two serif and sans serif fonts at 12 and 14-point sizes for differences in legibility, reading time, and general preference when read by an older population. A significant main effect of size was found for font legibility in that 14-point fonts were more legible to read than 12-point fonts. A marginal interaction was(More)
This study examined where individuals expect specific web-related objects to be located on a typical web page. The web objects examined were: web page title, internal and external grouping of links, a link to the homepage, internal search engine, and advertisement banner(s). The results suggest that users do have definable expectations concerning the(More)
BACKGROUND The purpose of this study was to develop a model to predict the emotional and behavioral responses to an avian flu outbreak. METHODS The participants were 289 university students ranging in age, income, and ethnic backgrounds. They were presented with scenarios describing avian flu outbreaks affecting their community. They reported their(More)
Activator of G protein signaling 3 (AGS3) activates the Gbetagamma mating pathway in yeast in a manner that is independent of heptahelical receptors. It competes with Gbetagamma subunits to bind GDP-bound Gi/o(alpha) subunits via four repeated G protein regulatory (GPR) domains in the carboxyl-terminal half of the molecule. However, little is known about(More)
Activator of G-protein signaling 3 (AGS3) is one of nine mammalian proteins containing one or more G-protein regulatory (GPR) motifs that stabilize the GDP-bound conformation of Galphai. Such proteins have revealed unexpected functional diversity for the "G-switch" in the control of events within the cell independent of the role of heterotrimeric G-proteins(More)
OBJECTIVE This study investigated the association between mindfulness, other resilience resources, and several measures of health in 124 urban firefighters. METHOD Participants completed health measures of posttraumatic stress disorder (PTSD) symptoms, depressive symptoms, physical symptoms, and alcohol problems and measures of resilience resources(More)
A model-free, biologically-motivated learning and control algorithm called S-learning is described as implemented in an Surveyor SRV-1 mobile robot. S-learning demonstrated learning of robotic and environmental structure sufficient to allow it to achieve its goals (finding high-or low-contrast views in its environment). No modeling information about the(More)
This study investigated how common online text a V ects reading performance of elementary school-age children by examining the actual and perceived readability of four computer-displayed typefaces at 12-and 14-point sizes. Twenty-seven children, ages 9 to 11, were asked to read eight children's passages and identify erroneous/substituted words while(More)
