1 Zick, Cathleen D.; Srisukhumbowornchai, SivitheeDoes housework matter anymore? The shifting impact of housework on economic inequalityIn recent years, American women's housework time has declined while American men's housework time has risen. We examine how these changes have affected economic inequality in America. Using time-diary data from the Time Use in Economic and Social Accounts, 1975-76 (N=1,484) and the American Time Use...Demography; Socioeconomic status; Household duties; Female; Male; United States; Economics2006-09-25
2 Jarrard, Richard D.Data report: high-resolution mineralogy for leg 199 based on reflectance spectroscopy and physical propertiesDuring Ocean Drilling Program Leg 199 in the equatorial Pacific, visible and near-infrared spectroscopy (VNIS) was used to measure the reflectance spectra (350?2500 nm) of 1343 sediment samples. Reflectance spectra were also measured for a suite of 60 samples of known mineralogy, thereby providing a...2004
3 Miller, Jan D.Evaluation of plantwide control strategies for coal preparation plantsThe quality of cleaned products from coal preparation plants is often variable due to natural fluctuations in the washability characteristics of the plant feed.
