Early warning signs of functional illiteracy: predictors in childhood and adolescence.

Early childhood, middle childhood, and early adolescence determinants of functional literacy in adulthood are investigated, using 20-year longitudinal data from a sample of black children of teenaged mothers from the Baltimore metropolitan area. Document literacy was assessed by a test that consisted of a subset of items of the National Assessment of Educational Progress (NAEP) adult literacy test. The Baltimore sample is compared to the NAEP sample. Family environmental factors, early childhood developmental level, and educational career factors were considered as predictors of young adulthood literacy. Preschool cognitive and behavioral functioning is highly predictive of literacy in young adulthood, even when the effects of family environmental characteristics, including living arrangements, the quality of the home environment, maternal education, and income, are controlled. Grade failure in elementary school is also associated with literacy, but this effect disappears when the measure of preschool abilities is controlled. Family environmental factors that are predictive of literacy include maternal education, family size in early childhood, maternal marital status, and income in middle childhood and early adolescence. Policy implications of these findings are discussed.

Effects of agricultural development policies on migration in peninsular Malaysia.

State planning plays a central role in Malaysia's social and economic development. The government's rural development policies are designed to promote agricultural incomes and help counterbalance ethnic inequalities. The Federal Land Development Authority (FELDA) implements one of the internationally most successful land development and resettlement programs. In this article, we quantify the impact of FELDA settlements on local out-migration rates, linking macro and micro approaches and using data from the Malaysian Family Life Survey, national censuses, and other sources. A model of instantaneous migration rates specifies an individual's migration rate as a function of individual-level sociodemographic characteristics, the level of urbanization of the origin and destination, and the extent of rural development at the district of current residence. Our results show that in the late 1960s and early 1970s, the existence of rural development centers in a district reduced the levels of out-migration to pre-1965 levels.

A method for analyzing backward recurrence time data on residential mobility.

Data on duration of current residence are used to estimate models of duration-dependent residential mobility rates. "We use the theory of backward recurrence times in renewal processes to infer the hazard rate of residential mobility from the density of the duration of current residence. We demonstrate that the inferences made using the asymptotic solution of the density of the backward recurrence times will be severely biased if the renewal process has not reached stability. We present an unbiased finite time solution and estimate univariate and multivariate models of residential mobility rates using 1980 U.S. census data on duration of current residence. These models include mover-stayer models represented by mixture densities. The multivariate analysis shows that the most important covariates of residential mobility are age, homeownership, race, and presence of school-aged children."

Consequences for children of their birth planning status.

Of 1,327 children younger than two in 1986 whose mothers were participants in the National Longitudinal Survey of Youth, 61% were wanted, 34% were mistimed and 5% were unwanted. Planning status is associated with the level of developmental resources the child receives at home: At ages one and older, mistimed and unwanted children score significantly lower on a scale measuring opportunity for skill development and on a scale measuring nonauthoritarian parenting style than their wanted peers; by preschool age, they also have significantly less-positive relationships with their mothers. Measures of the direct effects of planning status on development also indicate that mistimed and unwanted children are at a disadvantage: Those younger than two have higher mean scores for fearfulness than wanted infants and lower scores for positive affect; unintended preschoolers score lower on a measure of receptive vocabulary.
