Geo-Spatial Analysis of Population Density and Annual Income to Identify Large-Scale Socio-Demographic Disparities

open access: yesISPRS International Journal of Geo-Information, 2021
This paper describes a methodological approach that is able to analyse socio-demographic and -economic data in large-scale spatial detail. Based on the two variables, population density and annual income, one investigates the spatial relationship of ...

Density dependence and the control of helminth parasites.

open access: yes, 2006
1. The transient dynamics and stability of a population are determined by the interplay between species density, its spatial distribution and the positive and negative density-dependent processes regulating population growth. 2.

Spatiotemporal dynamics of population density in China using nighttime light and geographic weighted regression method*

open access: yesInternational Journal of Digital Earth, 2023
The distribution and dynamic changes of regional or national population data with long time series are very important for regional planning, resource allocation, government decision-making, disaster assessment, ecological protection, and other ...

Adaptive Non-Negative Geographically Weighted Regression for Population Density Estimation Based on Nighttime Light

open access: yesISPRS International Journal of Geo-Information, 2019
Nighttime light imagery provides a perspective for studying urbanization and socioeconomic changes. Traditional global regression models have been applied to explore the nonspatial relationship between nighttime lights and population density.

Impact of spatiotemporal land-use and land-cover changes on surface urban heat islands in a semiarid region using Landsat data

open access: yesInternational Journal of Digital Earth, 2021
Many factors are involved in urban heat island development, such as lack of green spaces, improper choice of building materials, densification, and other human activities. The aim of this research was to quantify the effects of land-use/land-cover (LU/LC)

Studying the water crisis in Delhi due to rapid urbanisation and land use transformation

open access: yesInternational Journal of Urban Sustainable Development, 2021
The paper records the spatial dynamics and water consumption pattern through statistical and spatial evidence. The objective of this paper is to analyse the impact of land use land cover change on water demand and supply pattern of a rapidly growing ...

Psychosocial Outcomes in Patients With Endocrine Tumor Syndromes: A Systematic Review

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction The combination of disease manifestations, the familial burden, and varying penetrance of endocrine tumor syndromes (ETSs) is unique. This review aimed to portray and summarize available data on psychosocial outcomes in patients with ETSs and explore gaps and opportunities for future research and care.

Developmental and genetic effects on behavioral and life‐history traits in a field cricket

open access: yesEcology and Evolution, 2019
A fundamental goal of evolutionary ecology is to identify the sources underlying trait variation on which selection can act. Phenotypic variation will be determined by both genetic and environmental factors, and adaptive phenotypic plasticity is expected

Evolutionary Stable Strategies Depending on Population Density [PDF]

open access: yes, 1990
The concept of evolutionary stable strategies is extended to include density dependence. Dynamical stability is shown to follow for two-strategy games and for symmetric payoff matrices.

Radial propagation in population dynamics with density-dependent diffusion

open access: yes, 2013
The population dynamics that evolves in the radial symmetric geometry is investigated. The nonlinear reaction-diffusion model, which depends on population density, is employed as the governing equation for this system. The approximate analytical solution
