We examine the crystallization and chain conformation behavior of semicrystalline poly(ethylene oxide) (PEO) and amorphous poly(vinyl acetate) (PVAc) mixtures with wide-angle X-ray diffraction (WAXD), small-angle X-ray scattering (SAXS), and small-angle neutron scattering (SANS) experiments. For blends with PEO weight fractions (wtPEO) greater than or equal to 0.3, below the melting point of PE...

n Contemporary studies indicate that teen pregnancy interferes with young women’s ability to graduate from high school and to enroll in and graduate from college. Conversely, planning, delaying and spacing births appears to help women achieve their education and career goals. Delaying a birth can also reduce the gap in pay that typically exists between working mothers and their childless peers ...

Adults are expert at recognizing faces, in part because of exquisite sensitivity to the spacing of facial features. Children are poorer than adults at recognizing facial identity and less sensitive to spacing differences. Here we examined the specificity of the immaturity by comparing the ability of 8-year-olds, 14-year-olds, and adults to discriminate houses differing in the spacing between fe...

Thirty-five individuals who had learned and relearaed 50 English-Spanish word pairs were tested for recall and recognition after an interval of 8 years. Two variables, the spacing between successive releaming sessions and the number of presentations required to encode individual word pairs, are excellent predictors of the likelihood of achieving permastore retention. Optimum recall occurs for w...
