How does one transform underprivileged youth and selfless volunteers into citizens who are autonomous, tolerant, and masters of their own destinies? This is the ambition of Nina Eliasoph’s latest work, which, at the same time, offers a remarkable portrait of American civic life. Civil society, to the extent that it promotes empowerment and fosters personal development, is often presented as a f...

We propose a modification of the classical Boussinesq approximation for buoyancy-driven flows of viscous, incompressible fluids in situations where viscous heating cannot be neglected. This modification is motivated by unresolved issues regarding the global solvability of the original system. A very simple model problem leads to a coupled system of two parabolic equations with a source term inv...

This paper considers the design of the optimal location-update area (LA) of the distance-based scheme for personal communication service (PCS) networks. We focus on the optimization of two design parameters associated with the LA: 1) initial position upon LA update; 2) distance threshold for triggering of LA update. Based on the popular continuous-time random walk (CTRW) mobility model, we prop...
