Income and Population Growth [PDF]
SSRN Electronic Journal, 2015 Do populations grow as countries become richer? In this paper we estimate the effects on population growth of shocks to national income that are plausibly exogenous and unlikely to be driven by technological change.

Effciency with Endogenous Population Growth [PDF]
Econometrica, 2004 In this paper, we generalize the notion of Pareto-e±ciency to make it applicable to environments with endogenous populations. Two di®erent e±ciency concepts are proposed, P -e±ciency and A-e±ciency. The two concepts di®er in how they treat people that are not born.

Growth, competition and cooperation in spatial population genetics [PDF]
H.P. de Vladar. Density-dependence as a size-independent
regulatory mechanism. J. Theor. Biol. (2006) vol. 238 (2) pp. 245-256, 2012 We study an individual based model describing competition in space between two different alleles. Although the model is similar in spirit to classic models of spatial population genetics such as the stepping stone model, here however space is continuous ...

On population growth with catastrophes [PDF]
Stochastic Models, 2022 In this paper we study a particular class of Piecewise deterministic Markov processes (PDMP's) which are semi-stochastic catastrophe versions of deterministic population growth models. In between successive jumps the process follows a flow describing deterministic population growth. Moreover, at random jump times, governed by state-dependent rates, the

Functioning of community sanitary complexes in rural India: Insights into selected states
Journal of Water, Sanitation and Hygiene for Development, 2023 An important component of the Swachh Bharat Mission is the construction of community sanitary complexes (CSCs) to address the unmet need for sanitation for households. The success, however, critically hinges on the operational management of CSCs.

Major Trends in Population Growth Around the World
China CDC Weekly, 2021 The world’s population continues to grow, albeit at a slower pace. The decelerating growth is mainly attributable to fertility declines in a growing number of countries. However, there are substantial variations in the future trends of populations across

Pubertal growth in height, sitting height and leg length in achondroplasia
Annals of Human Biology, 2021 Background: Children with achondroplasia (ACH) appear to lack a pubertal growth spurt in height. Aim To explore the growth spurt in height and its segments sitting height and leg length, in a large sample of ACH cases using growth curve modelling ...

Past insecticide exposure reduces bee reproduction and population growth rate
Proceedings of the National Academy of Sciences of the United States of America, 2021 Significance Global insect declines are profoundly concerning, especially for groups like bees that provide important services to humanity. However, we do not know the extent to which recognized drivers of decline, like pesticides, may produce carryover ...

Scientific Reports, 2021 In India, districts serve as central policy unit for program development, administration and implementation. The one-size-fits-all approach based on average prevalence estimates at the district level fails to capture the substantial small area variation.
