Written specifically for K–12 educators, this accessible book explains the processes involved in second-language acquisition and provides a wealth of practical strategies for helping English language learners (ELLs) succeed at reading. The authors integrate knowledge from two fields that often remain disconnected—linguistics and literacy—with a focus on what works in the classroom.

An Introduction to the Theory of Numbers

This book, which presupposes familiarity only with the most elementary concepts of arithmetic (divisibility properties, greatest common divisor, etc.), is an expanded version of a series of lectures for graduate students on elementary number theory. Topics include: Compositions and Partitions; Arithmetic Functions; Distribution of Primes; Irrational Numbers; Congruences; Diophantine Equations; Combinatorial Number Theory; and Geometry of Numbers. Three sections of problems (which include exercises as well as unsolved problems) complete the text.

Functional Inequalities Markov Semigroups and Spectral Theory

In this book, the functional inequalities are introduced to describe:
(i) the spectrum of the generator: the essential and discrete spectrums, high order eigenvalues, the principle eigenvalue, and the spectral gap;
(ii) the semigroup properties: the uniform intergrability, the compactness, the convergence rate, and the existence of density;
(iii) the reference measure and the intrinsic metric: the concentration, the isoperimetic inequality, and the transportation cost inequality.

Bad Girls Go Everywhere: The Life of Helen Gurley Brown

From Brown's first book, Sex and the Single Girl, a bold precursor to today's unapologetic Sex in the City, to her editing of the most widely read women's magazine in the world, Brown defied traditional mores to proclaim the unmarried woman's right to happiness. The first woman to publicly say there was another role available in the conservative context of the 1960s, Brown offered American women a revelation that resulted in a revolution.
