AIM To assess the association between child growth and teacher-reported behavior and academic standing, and neuropsychological performance. METHOD The heights of 344 public-school children were measured using standard procedures. Teachers were requested to complete two behavioral and one academic performance rating scales. Neuropsychological assessment consisted of the Edinburgh Handedness In...

The Agricultural Revolution accompanied, either as a cause or as an effect, important changes in human demographic systems. The consensus model is that fertility and mortality increased and health declined with the adoption of agriculture, compared to those for hunter-gatherers. Analysis of the agricultural transition relies primarily on archaeological and paleodemographic data and is thus subj...

The development of culturally relevant psychological assessment tools and intervention procedures has not been commensurate with the rate of Hispanic population growth in the United States. The development of valid and reliable test measures for the assessment of this population must be based on empirical investigations. In this article, we present normative data on multiple measures from the B...

We consider the distribution of pairwise sequence differences of mitochondrial DNA or of other nonrecombining portions of the genome in a population that has been of constant size and in a population that has been growing in size exponentially for a long time. We show that, in a population of constant size, the sample distribution of pairwise differences will typically deviate substantially fro...

If a population is growing in a randomly varying environment, such that the finite rate of increase per generation is a random variable with no serial autocorrelation, the logarithm of population size at any time t is normally distributed. Even though the expectation of population size may grow infinitely large with time, the probability of extinction may approach unity, owing to the difference...

The number of Latino immigrants in rural areas has increased substantially since 1990. Furthermore, many Latino immigrants are moving to rural communities in the Southeast, Midwest, and Northwest, which historically have not been immigrant destinations. This recent, rapid, and unexpected population growth in new rural destinations has focused public attention on immigration reform and fostered ...

Bringing about access to adequate housing remains a key challenge in South Africa. In 1997, it was estimated that 2.2 million households in South Africa were without adequate housing. It was further estimated that this figure would increase by 204 000 every year because of population growth, barring any effective intervention (Department of Housing 2000:2). The housing crisis has particularly d...

How much does environmental autocorrelation matter to the growth of structured populations in real life contexts? Interannual variances in vital rates certainly do, but it has been suggested that between-year correlations may not. We present an analytical approximation to stochastic growth rate for multistate Markovian environments and show that it is accurate by testing it in two empirically b...

We describe a method for co-estimating 4Nemu (four times the product of effective population size and neutral mutation rate) and population growth rate from sequence samples using Metropolis-Hastings sampling. Population growth (or decline) is assumed to be exponential. The estimates of growth rate are biased upwards, especially when 4Nemu is low; there is also a slight upwards bias in the esti...

We study the effect of technological knowledge on per-capita income and population in a Malthusian economy. Airy differential equations describe the evolution of knowledge. Consequently, the impact of technological knowledge on aggregate output is feeble before and strong after the Industrial Revolution. The economy exposed to Airy growth of knowledge evolves from a Malthusian regime into a Pos...
