OBJECTIVE The purpose of this study was to examine changes in women's directed attention, the ability to focus or concentrate, during the last trimester of pregnancy and during 1st week postpartum. DESIGN Pregnant women were tested at enrollment (during the 3rd trimester), at 37 weeks gestation, and during the 1st postpartum week for this descriptive,(More)
OBJECTIVE To determine if gravidas ages 35 years and older have greater conflict in adapting to pregnancy than do younger gravidas. DESIGN Static group comparison. SETTING Prenatal care facilities and prenatal education classes. PARTICIPANTS Sixty-four older gravidas (35 years and older) and 46 younger gravidas (32 years and younger) who were in their(More)
Utilizing the Two Micron All Sky Survey (2MASS) Second Incremental Data Release Catalog, we have retrieved near-IR magnitudes for several hundred hot subdwarfs (sdO and sdB stars) drawn from the Catalogue of Spectroscopically Identified Hot Subdwarfs (Kilkenny, Heber, & Drilling 1988, 1992). This sample size greatly exceeds that of previous studies of hot(More)
Many EHB stars have been found in short–period binaries, where the companions in these post–common envelope systems are either white dwarfs or dM stars; these systems are catalogued as hot subdwarfs because the subdwarf is the more luminous component. Hypothesized Roche–lobe overflow systems (with more massive companions) may largely be uncatalogued, since(More)
The 11th magnitude star LS IV−083 has been classified previously as an OB star in the Luminous Stars survey, or alternatively as a hot subdwarf. It is actually a binary star. We present spectroscopy, spectroscopic orbital elements, and time series photometry, from observations made at the Kitt Peak National Observatory 2.1m, Steward Observatory 2.3m,(More)
