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...

Indian agriculture is the largest private sector enterprise in the country of over 110 million farmers. It engages two-third of total workforce, contributes to 26 per cent of the GDP and nearly one-sixth of the total export earnings. India inherited a stagnant agriculture at the time of independence growing at an annual rate of growth of 0.3 per cent in the first half of the last century. Due t...

Catastrophic collapses of top predators have revealed trophic cascades and community structuring by top-down control. When populations fail to recover after a collapse, this may indicate alternative stable states in the system. Overfishing has caused several of the most compelling cases of these dynamics, and in particular Atlantic cod stocks exemplify such lack of recovery. Often, competition ...

a basic subject in economy is change in growth of population and it’s link to ‎other variables. if growth in population is consistent with other economic ‎circumstances, it would lead to economic growth, otherwise it would be ‎problematic. by using okun's law and population structures, this paper is ‎analysis the case for iran for 1974-2010. predictions are related to 2025 ‎horizon. the re...

Qualitative and quantitative differences in population growth patterns of Aphelenchoides rutgersi from Florida, A. sacchari from Jamaica, A. dactylocercus from Great Britain, and A. cibolensis from New Mexico were assessed on 28 species of fungi. The patterns of population growth of A. rutgersi and A. sacchari were statistically similar although not identical, and they differed considerably fro...
