Level 2 of Model I was designed to examine the interaction effects of AAEng, HisEng, and HisNEng, as well as the independent variables Teenmom, Momedu, PreHead, Povty, Madult, Cage, Csex, and Hdst. At Level 2, all variables were specified in the intercept, while only three ethnic groups were specified in the slopes (See Appendix for the detailed descriptions of model equations).
Madult and Hdst also were associated with higher levels of parental involvement: that is, mothers tended to participate in the parental programs more often when adult males were present in the household or their children were in a Head Start program.

Although retrospective analysis of the HDST in a large adult population showed a marked interdependence of the basal cortisol concentration, peak cortisol concentration, and increases in serum cortisol concentration (14), criteria that require a minimum increment in serum cortisol (13) are considered invalid because individuals who have a lower basal serum cortisol concentration because of recent ACTH deficiency may be maximally stimulated by the HDST and thus able to further increase cortisol secretion.
We studied 17 patients (14 females and 3 males; age range, 18-46 years) with suspected primary adrenal dysfunction that was subsequently ruled out via a normal cortisol response on the HDST. The patients were followed in the endocrinology clinic and underwent ACTH stimulation testing to exclude 21-hydroxylase deficiency and primary adrenal dysfunction suspected in the presence of other autoimmune disorders (such as hypothyroidism or diabetes mellitus).
A recent study sketches out the rationale for a gigantic High-Definition Space Telescope (HDST) that could undertake this quest.
The HDST would also make extraordinary breakthroughs in the study of black holes, dark energy, and cosmic evolution.
Meanwhile, STScI astronomers are studying concepts for what they call a High Definition Space Telescope (HDST), or "Hubble 2.0." HDST could have a segmented, deployable 12-meter mirror, be outfitted with cameras and spectrographs that cover the wavelength range from the near-infrared all the way into the UV, and leave the launch pad in the mid-2030s.
By spectroscopically studying Earth-like planets in the habitable zones of Sun-like stars, says Postman, "HDST will help us to answer one of the most fundamental questions we ever asked ourselves: are we alone?"
