LandScan Home Using an innovative approach with Geographic Information System and Remote Sensing, ORNL's LandScan™ is the community standard for global population distribution. At approximately 1 km resolution (30" X 30"), LandScan is the finest resolution global population distribution data available and represents an ambient population (average over 24 hours). The LandScan algorithm, an R&D 100 Award Winner, uses spatial data and imagery analysis technologies and a multi-variable dasymetric modeling approach to disaggregate census counts within an administrative boundary. Since no single population distribution model can account for the differences in spatial data availability, quality, scale, and accuracy as well as the differences in cultural settlement practices, LandScan population distribution models are tailored to match the data conditions and geographical nature of each individual country and region.
Diffusion of Innovation Theory Diffusion of Innovation (DOI) Theory, developed by E.M. Rogers in 1962, is one of the oldest social science theories. It originated in communication to explain how, over time, an idea or product gains momentum and diffuses (or spreads) through a specific population or social system. The end result of this diffusion is that people, as part of a social system, adopt a new idea, behavior, or product. Adoption means that a person does something differently than what they had previously (i.e., purchase or use a new product, acquire and perform a new behavior, etc.). 30+ WordPress Plugins for Statistics To grow your blog, you need to know something about who's visiting, why they're at your site, where they came from, and where they're going.

27 Visualizations and Infographics to Understand the Financial C I've said it before, and I'll say it again. If there's anything good that has come out of the financial crisis it's the slew of high-quality graphics to help us understand what's going on. Some visualizations attempt to explain it all while others focus on affected business. Others concentrate on how we, as citizens are affected. Some show those who are responsible. After you examine these 27 visualizations and infographics, no doubt you'll have a pretty good idea about what's going on.
ETHIOPIA COMMODITY EXCHANGE The Ethiopia Commodity Exchange (ECX) is a new initiative for Ethiopia and the first of its kind in Africa. The vision of ECX is to revolutionize Ethiopia’s tradition bound agriculture through creating a new marketplace that serves all market actors, from farmers to traders to processors to exporters to consumers. The ECX is a unique partnership of market actors, the Members of the Exchange, and its main promoter, the Government of Ethiopia. ECX represents the future of Ethiopia, bringing integrity, security, and efficiency to the market. ECX creates opportunities for unparalleled growth in the commodity sector and linked industries, such as transport and logistics, banking and financial services, and others.
GPOPDB Home Page The database divides the earth into Big Cells, rectangular grids of 20 minutes of latitude by 30 minutes of longitude, an area of around 2,000 square kilometers at the equator. Some country data are more detailed. The smaller Mini Cells make rectangular grids of 5 minutes of latitude by 7.5 minutes of longitude. There are 6 Big Cells in a "square" degree, and each Big Cell contains 16 Mini Cells. Data Visualization, Design and Information Munging // Martin Krzywinski / Genome Sciences Center Schemaball is a flexible schema visualizer for SQL databases. The purpose of Schemaball is to help visualize the relationships between tables. Tables are related by foreign keys, which are fields which store the value of a record field from another table. Foreign keys create a lookup relationship between two tables.
Dubai Student Designs Mobile Prenatal Care Device - Education - GOOD It’s not hard to guess from his technology competition name—The Hex Pistols—that 20-year-old Shawn Frank is a fan of music. He's also a strong advocate of ensuring that women in developing nations have access to quality prenatal care. Six months ago, while walking to an internship, Frank came up with the idea for momEcare, a mobile device that helps provide medical assistance to pregnant women who can't get to a hospital. Now Frank, who just graduated from the computer science program at the University of Wollongong in Dubai, is headed to Microsoft's Imagine Cup, a technology competition for socially conscious high school and college students happening next week in New York City (we've covered the other young finalists here, here and here). I caught up with him to find out what first sparked his interest in technology and learn more about how momEcare works.
9 Ways to Visualize Proportions – A Guide With all the visualization options out there, it can be hard to figure out what graph or chart suits your data best. This is a guide to make your decision easier for one particular type of data: proportions. Maybe you want to show poll results or the types of crime over time, or maybe you're interested in a single percentage. Here's how you can show it. We all know about the pie chart. The circle represents the whole, and the size of wedge represents a percentage of that whole.
