Here is a wide-ranging, comprehensive account of the mathematical formulation of problems involving free boundaries as they occur in such diverse areas as hydrology, metallurgy, chemical engineering, soil science, molecular biology, materials science, and steel and glass production. Many new methods of solution are discussed, including modern computer techniques which address multidimensional, multiphase practical problems.

Though it incorporates much new material, this new edition preserves the general character of the book in providing a collection of solutions of the equations of diffusion and describing how these solutions may be obtained.

The enclosed papers are the culmination of a project Dr. John Crank and Dr. Colleen Kadleck carried out assessing issues facing the police into the early 21st century. The papers are future oriented, in the sense that they anticipate trends visible today. Everywhere, our scholars found that the organizational concept, practice, and function of the police undergoing transition. Yet, the seeming state-level hardening of the police function was ubiquitous. Two themes were noteworthy. On the one hand, in developing or second world' countries, police face endemic problems of corruption, organized...

The research revolution in police work has uncovered a multitude of data, but this contemporary knowledge has done very little to change the way things are done in most police departments across the U.S., where the prevalent form of policing is based on the traditional model of district assignments and random preventive patrol. Mission-Based Policing unveils a new paradigm that transitions policing away from practices that while long-held, have inadequately dealt with serious crime.

Drawn from the work of scholars on the cutting edge of police...
