GeoDesign Case Studies Sought

Esri logoEsri is actively seeking GeoDesign case studies for possible publication. The objective is to demonstrate GeoDesign principles in practice as a way to communicate these concepts to folks who are interested in learning more about GeoDesign. The cases need to be actual cases, not theoretical demonstrations. Cases may qualify for use in a GeoDesign Case Study book (currently being written), or they may be used as GeoDesign stories for publication in ArcNews or elsewhere.

The stipulation is that the GeoDesign case studies involve some aspect of:

  • ArcGIS technology
  • design in geographic space
  • identification of issues
  • process evaluation and analysis
  • impact simulations
  • fast iteration
  • alternative scenario generation and comparison
  • decision making

Additionally, they could involve but are not restricted to demonstrating:

  • Sketching
  • Workflow integration
  • Collaboration
  • 3D and 4D visualization
  • Holism and interdependency
  • Science- and value-based decision making

All materials (e.g., written contributions, images, photos, maps, models, data) must allow permission for use in publication. If you are interested in sharing your GeoDesign solutions or have questions, please contact Shannon McElvaney at smcelvaney@esri.com.

A Spatial Measure of Neighborhood Level Racial Isolation Applied to Low Birthweight, Preterm Birth, and Birthweight in North Carolina

Spatial and Spatio-temporal Epidemiology, Available online 30 June 2011

“Highlights:

  • We developed a spatial measure of neighborhood level racial isolation of blacks.
  • We related this index to birth outcomes in the southern state of North Carolina.
  • Black isolation is associated with poor birth outcomes among blacks and whites.
  • Whites showed greater increases in odds of each poor birth outcome than did blacks.

“Research on racial residential segregation (RRS) and birth outcomes has focused on RRS at a broad geographic scale, in an aspatial framework, and in northern US cities. We developed a spatial measure of neighborhood level racial isolation of blacks. We examined the association between this new measure and low birthweight, preterm birth, and birthweight in the southern state of North Carolina. Natality data were obtained from the North Carolina Detailed Birth Record 1998–2002 files. Using multiple regression with cluster corrected standard errors, infants born to black and white mothers living in black isolated neighborhoods had, on average, decreased birthweight, and increased odds of low birthweight and preterm birth compared to their counterparts in less isolated areas. White mothers in predominantly black neighborhoods experienced greater increases in odds of each poor birth outcome than did black mothers. Black isolation may be proxying concentrated socioeconomic disadvantage, including disamenities in the built environment.”

Motivations Driving Government Adoption of the Geoweb

GeoJournalGeoJournal, Published Online 11 May 2011

Peter A. Johnson and Renee E. Sieber

“Recent increases in the use of Web 2.0 and Geoweb technologies by citizens have led many governments to investigate the adoption of these technologies. This research examines the motivations driving multiple levels of government in Quebec, Canada to consider the adoption of the Geoweb within a context of rural development. We present results from a series of interviews with key government representatives that identifies the SWOT (strengths, weaknesses, opportunities, and threats) of the Geoweb within provincial and municipal government. Respondents define two implementations of the Geoweb, informational and participatory, indicating that SWOT differs for each. This research concludes that for government to implement an informational Geoweb, there are few barriers, but that a participatory Geoweb will require a more substantial, and potentially long-term renegotiation of the relationship between citizen and government.”
