Effects of font design and electronic display parameters upon text legibility were determined using a threshold size method. Participants' visual acuity (inverse of the minimum detection size, representing the threshold legibility for each condition) was measured using upper- and lowercase letters and lowercase words in combinations of 6 fonts, 3(More)
PURPOSE To evaluate accommodative lag before, during the year of, and after the onset of myopia in children who became myopic, compared with emmetropes. METHODS The subjects were 568 children who became myopic (at least -0.75 D in each meridian) and 539 children who were emmetropic (between -0.25 D and +1.00 D in each meridian at all visits) participating(More)
BACKGROUND Despite treatment advances, major depressive disorder (MDD) is still a significant cause of morbidity and mortality. Current therapies frequently fall short of providing full remission. In addition, physical symptoms are commonly seen in MDD patients, increasing overall morbidity and health care utilization. Duloxetine hydrochloride, a dual(More)
Collaborative coping (i.e., spouses pooling resources and problem solving jointly) may be associated with better daily mood because of heightened perceptions of efficacy in coping with stressful events. The study examined the daily processes of collaborative coping (individuals' perceptions that the spouse collaborated), perceived coping effectiveness(More)
"Creative" is a word with many uses. Sometimes it is used to describe the potential of a person to produce creative works whether they have produced any work as yet or not. Sometimes it is used to describe everyday behaviors as, for example, when a nursery school curriculum is said to encourage creative activities such as drawing or story telling. In this(More)

The Pluto Energetic Particle Spectrometer Science Investigation (PEPSSI) comprises the hardware and accompanying science investigation on the New Horizons spacecraft to measure pickup ions from Pluto's outgassing atmosphere. To the extent that Pluto retains its characteristics similar to those of a " heavy comet " as detected in stellar occultations since(More)
PURPOSE To evaluate refractive error, axial length, and relative peripheral refractive error before, during the year of, and after the onset of myopia in children who became myopic compared with emmetropes. METHODS Subjects were 605 children 6 to 14 years of age who became myopic (at least -0.75 D in each meridian) and 374 emmetropic (between -0.25 D and(More)
PURPOSE To compare ocular component growth curves among four refractive error groups in children. methods Cycloplegic refractive error was categorized into four groups: persistent emmetropia between -0.25 and +1.00 D (exclusive) in both the vertical and horizontal meridians on all study visits (n = 194); myopia of at least -0.75 D in both meridians on at(More)
PURPOSE We propose that eyelid squint can reduce the impact of several conditions known to cause eyestrain such as uncorrected refractive error, accommodative dysfunction, presbyopia, and glare. Clinicians commonly accept that squint improves visual acuity (VA) in the presence of refractive error, and even though the benefit of eyelid squint in bright light(More)
