We used data from the Midlife Development in the United States (MIDUS I) (N = 2,031) to compare three models of how work-family conflict and enrichment might operate to predict well-being (mental health, life satisfaction, affect balance, partner relationship quality). We found no support for a relative-difference model in which the conflict-enrichment balance predicted outcomes. In the work-to...

A method is introduced for quantitating protein synthetic rates in humans by use of (2)H(2)O. Its validity was tested in subjects with end-stage renal disease. Six clinically stable subjects, hemodialyzed three times weekly, ingested (2)H(2)O to a body water (2)H enrichment of approximately 0.4%. On dialysis, body water enrichment declined to approximately 0.1%. Enrichment of the alpha-hydrogen...

41 Environmental enrichment induces powerful changes in the adult cerebral cortex. 42 Studies in primary sensory cortex have observed that environmental enrichment 43 modulates neuronal response strength, selectivity, speed of response and 44 synchronization to rapid sensory input. Other reports suggest that non-primary sensory 45 fields are more plastic than primary sensory cortex. The consequ...

We summarize recent results assessing the carbon and silicon abundances of the intergalactic medium (IGM) using the ‘pixel optical depth’ technique. We briefly discuss the implications of these results for models of intergalactic enrichment, focusing on distinguishing ‘early’ z ≫ 4 enrichment by the first generations of stars and objects from ‘late’ enrichment by 2 ∼ z ∼ 5 Lybreak galaxies. We ...
