The Spanish language and Hispanic culture have left indelible impressions on the landscape of the southwestern United States. The role of cultural and geographical influence has had dramatic effects on the sustainability of the Spanish language and also its development and change. In a linguistic exploration that delves into a language as it is spoken by the Hispanic population of New Mexico and southern Colorado, historical substantiation shows the condition of New Mexican Spanish and what the future holds for its speakers. With two major dialect regions, one in the north and one in the south, detailed maps illustrate the geography of linguistic variation for the Spanish spoken in the region, whose generations of speakers were not only influenced by other languages, but also developed their own variations of words and structure out of need or innovation.

This diverse language has evolved since its origin in Spain with influences that include Native American languages, exposure to English, and Mexican immigration in the twentieth century. Snippets of New Mexican folklore and folk etymology give voice to that evolution. Though this work doesn't attempt to save the New Mexican Spanish language, Bills and Vigil detail the effects of inevitable encroachment that intensified during the twentieth century and seriously threaten the continued viability of this unique dialect.

A comprehensive, in-depth presentation of theoretical underpinnings and mathematical techniques
This is the first book of its kind to combine all the theories of molecular reaction dynamics and chemical kinetics in a single source. It provides a sophisticated treatment of the material that functions both as a professional reference and a high-level text for PhD and postdoctoral researchers.
Advanced Molecular Dynamics and Chemical Kinetics offers exceptional, in-depth coverage and includes a complete discussion of the theoretical as well as mathematical presentation of techniques. It features relevant exercises as well as comprehensive coverage of:
* Second Quantization
* Semiclassical Theory
* Quantum Theory of Reaction Rates
* Feynman Path Integrals
* Wavepacket Propagation and Grid Methods
* Photodissociation
* Molecular Properties of Solvated Molecules
* Quantum Model for Electron Transfer
* Electron Transfer Coupling Elements
* Proton Transfer Reactions in Solution
This is the ideal reference for seasoned professionals in molecular reaction dynamics as well as for younger researchers who may want to enter the field or simply wish to learn more about it.

The most complete introduction available to molecular dynamics and the calculation of rate of reaction
This unique textbook provides a unified treatment of molecular reaction dynamics and chemical kinetics in the gas phase, on surfaces, and in solution. It goes beyond the standard textbook topics related to reactions to include concepts from molecular dynamics calculations as well as methods for treating reactions in solution.
Featuring a thorough mathematical presentation that fosters understanding and mastery of all topics covered, Introduction to Molecular Dynamics and Chemical Kinetics:
* Covers all the basic concepts and practices related to mathematical model systems used to calculate probability for chemical reactions
* Provides complete theoretical discussions, including areas of Kramers' theory and Marcus theory dealing with reactions in solutions
* Introduces an innovative system of molecular units for molecular dynamics calculations--provides conventional units as well
* Describes all mathematical derivations necessary for obtaining formulas
* Uses numerous exercises to clarify both the derivations in the text and the effects being studied
* Explains how to solve the exercises in its appended "Answers" section
* Includes special appendices that summarize background information needed to perform required mathematical calculations and understand relevant theories

This text is now available as a two-volume set. Volume 1 covers both molecular reaction dynamics and chemical kinetics, and their respective theories in a single source. It also includes problems and solved exercises. Volume 2 concerns molecular reaction dynamics - the use of mathematical model systems based on statistical assumptions to calculate the probability of a chemical reaction and chemical kinetics. It combines all the theories of chemical kinetics and molecular reaction dynamics into a single location.
