After mapping premature births in Cincinnati from the early 2000s, researchers confirm that there is no single factor in a hotspot that explains a higher rate. In one area it might be smoking, another older mothers, another diabetes... Still, identifying that factor and addressing it could help lower early births. The data actually pre-dates many health efforts undertaking by the city since that time.

“Fertiliser is the Trojan horse of Sri Lanka’s Green Revolution,” per J M R Sarath Bandara, who teaches agricultural biology at University of Peradeniya in Kandy in Central Province. One explanation for the very high rate of kidney failure in the country may track back to its widespread use. Among the tools used to explore the cause: GIS.
Edge effects may over estimate the number of food deserts.
Results: Analysis of household accessibility to food outlets by neighbourhood socioeconomic distress level indicated that residents in the most distressed neighbourhoods tended to have better accessibility to all types of food retailers. In the most distressed neighbourhoods, 79 percent of residences were within walking distance of a grocery store, compared to only 10 percent in the least distressed neighbourhoods.
When the edge effect was neglected, 37 percent of distance estimates proved inaccurate. Average accessibility to all food retailer types improved dramatically when food outlets adjacent to the study area were considered, thereby controlling for the edge effect.
Conclusion: By neglecting to consider food retailers just outside study area boundaries, previous studies may significantly over-report the actual distance necessary to travel for food.
