Neighborhood change is a social determinant of health (SDOH) that has been associated with adverse and increased care utilization. The number cities neighborhoods undergoing intense gentrification, defined as an influx wealthy populations into working-class neighborhood, not highly numerous. Public systems are increasingly engaged SDOH in community-level interventions. Pathways to study affect ...

Software-Defined Networking (SDN) has been one of the major buzz words of the networking industry for the past couple of years. And yet, no clear definition of what SDN actually covers has been broadly admitted so far. This document aims to clarify the SDN landscape by providing a perspective on requirements, issues, and other considerations about SDN, as seen from within a service provider env...

We describe here preliminary results of our Comet implementation of generic abstractions for Very LargeScale Neighborhoods. These neighborhoods are used in local search. Their size is exponential but the best neighbor can be computed in polynomial time. They have proven to be very efficient on a large set of problems. However designing such neighborhoods requires high development efforts. Our o...

In the Euclidean TSP with neighborhoods (TSPN) problem we seek a shortest tour that visits a given set of n neighborhoods. The Euclidean TSPN generalizes the standard TSP on points. We present the first constant-factor approximation algorithm for TSPN on an arbitrary set of disjoint, connected neighborhoods in the plane. Prior approximation bounds were O(log n), except in special cases. Our app...

We tested the hypothesis that neighborhoods with hazardous waste sites may no longer be undesirable places to live if they have been at least partly remediated. We collected 377 questionnaires (42% response rate) administered from within one-half mile of the number 1, 4, and 12 hazardous waste sites on the National Priority List (Superfund). These neighborhoods were rated higher quality than ne...

The geographic concentration and diffusion of crime deviancy are longstanding criminological inquiries, yet few studies have examined how certain illicit behaviors transcend neighborhood borders connect neighborhoods in patterns deviancy. A structural interdependence may account for the enduring nature spread crime, making it critical to understand connected guide prevention disruption efforts....
