This book introduces students to optimization theory and its use in economics and allied disciplines. The first of its three parts examines the existence of solutions to optimization problems in Rn, and how these solutions may be identified. The second part explores how solutions to optimization problems change with changes in the underlying parameters, and the last part provides an extensive description of the fundamental principles of finite- and infinite-horizon dynamic programming. A preliminary chapter and three appendices are designed to keep the book mathematically self-contained.

The 2006 INFORMS Expository Writing Award-winning and best-selling author Sheldon Ross (University of Southern California) teams up with Erol Peköz (Boston University) to bring you this textbook for undergraduate and graduate students in statistics, mathematics, engineering, finance, and actuarial science. This is a guided tour designed to give familiarity with advanced topics in probability without having to wade through the exhaustive coverage of the classic advanced probability theory books. Topics include measure theory, limit theorems, bounding probabilities and expectations, coupling and Stein's method, martingales, Markov chains, renewal theory, and Brownian motion. No other text covers all these advanced topics rigorously but at such an accessible level; all you need is calculus and material from a first undergraduate course in probability.

Algae are ubiquitous; a multitude of species ranging from microscopic unicells to gigantic kelps inhabit the world's oceans, freshwater bodies, soils, rocks, and trees, and are responsible for most of the global production of organic matter by photosynthesis. They thus play a fundamental role in the world's ecosystems and a reliable and modern introduction to their kaleidoscopic diversity, systematics, and phylogeny is indispensable. In this textbook, the main groups of algae (divisions or phyla) are considered in turn. Each chapter begins with a summary of the principal characteristics of the group and interesting aspects of ecology and evolution. The final chapter is a synthesis, in which the phylogeny of the algae is discussed in relation to the evolution of other living organisms, primarily on the basis of evidence from recent molecular studies. This book is the completely revised and updated edition of a highly acclaimed German work, which was heralded for its clarity as well as its breadth and depth of information. This new edition takes into account recent reevaluations in algal systematics and phylogeny provided by the powerful techniques of molecular genetics and electron microscopy, as well as more traditional life history studies. The book will be appropriate as an undergraduate text and as a reference for professionals in the field.

For one- or two-semester junior or senior level courses in Advanced Calculus, Analysis I, or Real Analysis. This text prepares students for future courses that use analytic ideas, such as real and complex analysis, partial and ordinary differential equations, numerical analysis, fluid mechanics, and differential geometry. This book is designed to challenge advanced students while encouraging and helping weaker students. Offering readability, practicality and flexibility, Wade presents fundamental theorems and ideas from a practical viewpoint, showing students the motivation behind the mathematics and enabling them to construct their own proofs.

The book is an indispensable companion to all students of biology, but particularly those enrolled in courses concerning experimental design, data analysis, hypothesis testing, research methods, or any practical project work.

Master BDD to deliver higher-value software more quickly

To develop high-value products quickly, software development teams need better ways to collaborate. Agile methods like Scrum and Kanban are helpful, but they're not enough. Teams need better ways to work inside each sprint or work item. Behavior-driven development (BDD) adds just enough structure for product experts, testers, and developers to collaborate more effectively.

Drawing on extensive experience helping teams adopt BDD, Richard Lawrence and Paul Rayner show how to explore changes in system behavior with examples through conversations, how to capture your examples in expressive language, and how to flow the results into effective automated testing with Cucumber. Where most BDD resources focus on test automation, this guide goes deep into how BDD changes team collaboration and what that collaboration looks like day to day. Concrete examples and practical advice will prepare you to succeed with BDD, whatever your context or role.

- Learn how to collaborate better by using concrete examples of system behavior

- Identify your project's meaningful increment of value so you're always working on something important

- Begin experimenting with BDD slowly and at low risk

- Move smoothly from informal examples to automated tests in Cucumber

- Use BDD to deliver more frequently with greater visibility

- Make Cucumber scenarios more expressive to ensure you're building the right thing

- Grow a Cucumber suite that acts as high-value living documentation

- Sustainably work with complex scenario data

- Get beyond the "mini-waterfalls" that often arise on Scrum teams

This is the third edition of the highly successful book, Biological Science. The text has been revised and updated to provide comprehensive coverage of the latest syllabuses. New material has been added in the following areas: human health and disease, microbiology and biotechnology, and the applications of genetics. Questions and practical work permeate the text and useful appendices are included covering biological chemistry, biological techniques and statistics. Biological Science is available as two soft cover volumes and as a combined volume hardback.

A revised and rearranged fourth edition of our previously titled CXC Biology. Comprehensively covering the CSEC syllabus requirements, this full-colour edition contains carefully controlled language to make the text accessible for a wide ability range. Biology for CSEC includes questions throughout to test understanding in progressive steps and reinforces new knowledge and concepts through revision questions at the end of each chapter. This edition also incorporates many investigations throughout the text, almost all of which could be used for the assessment of practical skills, and a full apparatus list which takes into account the new guidelines on safety. A detailed contents list, a complete glossary and a comprehensive index are also included.

Two new titles that provide comprehensive coverage of the syllabus. Biology Unit 2 for CAPE(R) Examinations has been developed to match the requirements of Unit 2 of the CAPE(R) Biology syllabus. The course provides total coverage of Unit 2 of the CAPE(R) Biology syllabus, with worked examples to help students develop their problem-solving skills. Written by best-selling authors Mary and Geoff Jones and CAPE(R) Biology teacher and examiner Myda Ramesar, this textbook is in full-colour and is written in an accessible style.

Success in your calculus course starts here! James Stewart's CALCULUS texts are world-wide best-sellers for a reason: they are clear, accurate, and filled with relevant, real-world examples. With CALCULUS, Eighth Edition, Stewart conveys not only the utility of calculus to help you develop technical competence, but also gives you an appreciation for the intrinsic beauty of the subject. His patient examples and built-in learning aids will help you build your mathematical confidence and achieve your goals in the course!

This book, the third of a three-volume work, is the outgrowth of the authors' experience teaching calculus at Berkeley. It is concerned with multivariable calculus, and begins with the necessary material from analytical geometry. It goes on to cover partial differention, the gradient and its applications, multiple integration, and the theorems of Green, Gauss and Stokes.
