The arrangement of things in n-dimensional space is specified as Spatial. Spatial data consists of values that denote the location and shape of objects and areas on the earth’s surface. Spatial information includes facts such as location of features, the relationship of geographic features and measurements of geographic features. The spatial cognition is a primal area of study in various other ...

Goodchild: Neogeography implies a reinventing of geography, in which the traditional roles of expert producer of geographic information and amateur user have broken down, with the amateur becoming both a producer and user—or what some have termed a prosumer. Implicit is a defi nition of geography as a discipline devoted to the production of geographic information; most contemporary geographers ...

A standard optimal investment model can be used to analyse an individual’s decision to accumulate social capital. We analyse six facts that support the predictions of this individualbased approach: (1) social capital first rises and then falls with age, (2) social capital declines with expected mobility, (3) social capital rises in occupations with greater returns to social skills, (4) social c...

We reconcile trade theory with plant-level export behavior, extending the Ricardian model to accommodate many countries, geographic barriers, and imperfect competition. Our model captures qualitatively basic facts about U.S. plants: (i) productivity dispersion, (ii) higher productivity among exporters, (iii) the small fraction who export, (iv) the small fraction earned from exports among export...

On-line news sources provide a large and comprehensive corpus of world events and news entities. The Lydia project (www.textmap.com) analyzes over a thousand on-line newspapers every day to discover news trends, sentiments, and geographic biases. The aim of the project is to deliver news analysis on a scale of content that would be impossible for a person to read, and to mine the data to discov...

A nation's economic geography can have an enormous impact on its development. In Thailand, we show that a high concentration of enterprise in an area predicts high subsequent growth in and around that area. We also find spatially contiguous convergence of enterprise with stagnant areas left behind. Exogenous physiographic conditions are correlated with enterprise location and growth. We fit a s...

Lung cancer is one of the most fascinating human cancer problems of to-day. That this form of cancer, in a series of countries, has increased to a terrifying degree in this century, is no longer doubted. A number of facts are, however, still unknown, or disputed. As the incidence of lung cancer varies considerably between the many countries which show a definite increase, and as conditions of l...
