Seth Dixon's curator insight, March 11, 2013 1:03 PM

The Central Place Theory is a model that is not used much today in academic geography, but given it's explicitly spatial nature, it is used in many geography curricula (including AP Human Geography) to show systems thinking and spatial patterns.  This powerpoint goes over the main ideas of the theory developed by Walter Christaller as well as some examples.

This is interesting. Threshold and ranges are excellent tools to market goods and services especially within the hexagon model but also with statistical informaton on socioeconomic status and dispersement within a population for marketing purposes. Thanks- great information.

Seth Dixon's curator insight, July 2, 9:50 AM

The hijab is an incredibly complex cultural artifact full of social meanings all over the political spectrum.  This poster shows some of the social pressures exerted on women in Iran to wear the hijab.  This poster comes from Iran where the government is using this platform to encourage traditional values and gendered norms using a chocolate bar/candy analogy.  This poster struck a nerve on social media throughout the Middle East in part because blends some modern cultural diffusion elements with some older folk traditions.  Many hijab-wearing women don't want other women to be shamed into conforming, and many women wear it the hijab in public, but privately subvert the cultural norms on social media.  What stereotypes and perspectives are embodied in this poster?  Why do you think this poster was seen as inflammatory or culturally insensitive by many?  This image would be a great discussion starter for cultural  patterns and process as well as the geography of the Middle East.

It is often noted that the cultural composition of the United States is undergoing a shift, referred to by some as the "Browning of America."  The story of Asian and Hispanic growth in the United States are occurring simultaneously, which makes many assume that they are growing for the same reasons.  The data clearly shows that this is not the case.

As reported by the BBC, this change in the legal use of geospatial information could have a huge impact on many industries.  Some are fearful that it could represent an invasion of privacy, and others see this as a way to harness new satellite technology to provide higher resolution data and improved data quality for researchers.
