Population density and mobility.

Hyper Mobility and Low Back Pain in the Athletic Population

Objectives: It is important to recognize any risk factors for the development of injuries in the athletic population. The aim of this study was to investigate the association between joint hyper mobility and low back pain in Iranian hyper mobile and non-hyper mobile athletes. Methods: 50 athletic patients with low back pain (age=23.20±12.79 years) and 51 healthy athletes (age=24.28&pl...

Mobility and population dynamics

Population Spatial Mobility: Monitoring, Methodology of Formation, Features of Regulation

Spatial mobility is a topical concept of analytical migration science, which makes it possible to assess the desires, readiness and capabilities of the population to move over certain distances and time. In the management of spatial mobility assessment requires the organization of systematic monitoring, which includes identifying the mobility potential in spatial and temporal interpretation, th...

Modeling human population patterns on tree density

In order to evaluate the possible correlation between the tree density and the human population density, the forested area in Nav Asalem district located in Guilan Province was selected. The descriptors of tree number and basal area per hectare as well as the stand density index were used to determine the tree density, which was conducted from a 2014 forest inventory including 62 cluster (558 p...

Interregional Interactions and Population Mobility

The institutional level at which policies should be determined is an important issue that has been extensively treated in the economics literature. In particular, the literature has discussed to what extent decentralization of policy decisions give an inefficient outcome. With a homogeneous population and perfect population mobility, as it conventionally is modeled, the following result is deri...
