Research: Early Childhood Education: Issues for a New Decade
Abstract The past two decades have provided early childhood educators with new insights, information and additional questions regarding the care and education of young children. This article provides a review of the past decade and suggests issues that should be addressed in the decade of the '80s. Consensus-seeking on these issues should be of interest to all persons concerned with young children.—N.L.Q.
Day Care in the Next Decade: 1980-1990.
Over the next decade the growth in the number qf preschool children with working mothers is expected to be rapid, both because qf the increase in the total number qf children and because more of their mothers will be employed. This raises an important concern, since the supply qf individual day care providers appears to be shrinking at the same time that the need fobr such care is increasing. Most evidence points to increased parental dependence on group care, not only fbr their 3to 5-year olds, but also for infants and toddlers. Demographic, economic and attitudinal factors, as well as public policy, have contributed to this trend and can be expected to play a
Characterization of Aqueous Dispersions and Gels Made of Sodium Caseinate and Basil Seed Gum: Phase Behavior, Rheology, and Microstructure
The interactions between sodium caseinate (NaCas) and basil seed gum (BSG) in the presence of calcium chloride (CaCl 2 ) were investigated. The phase behavior of the mixed aqueous dispersions and their gels revealed a homogeneous mixture, obtained at the higher concentrations of both CaCl 2 and BSG. The Herschel-Bulkley model sufficiently fitted the flow behavior of the mixture solution data. Apparent viscosity increased significantly ( p  < 0.05) by increasing the concentration of BSG, where the addition of CaCl 2 had no significant effect on the viscosity of the samples ( p  > 0.05). Furthermore, there was an increase in thixotropy due to the higher concentrations of BSG and CaCl 2 . Based on the frequency sweep test, at the low frequencies, a more gel-like behavior was observed in the case of the higher concentrations of either BSG or CaCl 2 . The rheological and SEM data suggested that the stronger structure of NaCas-BSG gel in the presence of the higher concentrations of CaCl 2 was related to the induction of complex formation between the two biopolymers.
