Show moreKerr measurements, ellipsometry, and quasielastic light scattering have been used to probe nematic fluctuations and nematic wetting at an isotropic liquid crystal-substrate interface in four generations of liquid crystalline monodendrons and dendrimers. We find that the pretransitional behavior is qualitatively similar to that of low molecular weight liquid crystals, exhibiting a Landau-like divergence of the relaxation time and a logarithmic divergence of the optical retardation on approaching the nematic-isotropic phase transition from above. Quantitatively, we find that the transition temperatures of the monodendrons are typically about 0.5 K above the supercooling limit of the isotropic phase and that the orientational viscosities may be fit to a power law in molecular weight Mn, where the exponent ≤ 1.0.

Show moreAs welfare caseloads fall and provisions of welfare reform are implemented in state and local welfare offices, there is a growing interest in families and individuals who leave the welfare rolls. However, welfare caseloads have always been dynamic, with families entering and leaving assistance programs each month. To interpret information on families leaving welfare since welfare reform, it is necessary to know what happened to families who left welfare in the past as well. This is a study of a third quarter, 1996 cohort of welfare leavers, who stopped receiving cash assistance before welfare reform went into effect. It is intended to provide a basis of comparison for future studies of families leaving welfare under welfare reform.
