Maintaining Key Services While Retaining Core Values: NYC Transit’s Environmental Justice Strategies

"Environmental Justice"

Environmental Justice

Nature is reacting to the activities of modern society in unique and largely unexpected ways. The spread of acidified rain to every continent, a worldwide decline of forested lands, and the ubiquitous presence of persistent organic pollutants due to industrial experiments in biochemistry suggest that the contemporary naturesociety relation includes phenomena unlike any that were previously know...

Convexifying Monotone Polygons while Maintaining Internal Visibility

Let P be a simple polygon on the plane. Two vertices of P are visible if the open line segment joining them is contained in the interior of P . In this paper we study the following questions posed in [5, 6]: (1) Is it true that every non-convex simple polygon has a vertex that can be continuously moved such that during the process no vertex-vertex visibility is lost and some vertex-vertex visib...

Environmental justice in action.

Background: Congenital talipes equinovarus (CTEV) is a common developmental disorder of the foot, affecting between 1 and 4.5 per 1000 live births. The aetiology is not well elucidated. While both genetic and environmental factors are implicated, no specific genes have been identified and little is known about environmental risk factors. Methods: We conducted a case-control study of idiopathic ...

Transforming planar graph drawings while maintaining height

There are numerous styles of planar graph drawings, notably straight-line drawings, poly-line drawings, orthogonal graph drawings and visibility representations. In this note, we show that many of these drawings can be transformed from one style to another without changing the height of the drawing. We then give some applications of these transformations.
