Canals and Dams: Investigate Feats of Engineering invites children ages 9 and up to explore the innovation and physical science behind the amazing waterways and barriers our world depends on. Trivia and fun facts illustrate engineering ingenuity and achievements from ancient aqueducts to the Suez Canal and the Hoover Dam. Readers will discover that engineers and builders alike put their lives on the line to advance civilization, experiencing triumphs and tragedies in building big. Through dazzling success and heartbreaking failure, they developed increasingly sophisticated tools and building methods. Activities and projects encourage children to explore the engineering process and to try, try again through trial and error. They'll engage in hands-on explorations of buoyancy, Newton's third law of motion, and forces that push and pull structures. They'll create a paper-cup zip line, build an arch, and simulate a tsunami, while experimenting with gravity, hydroponics, and velocity. In Canals and Dams: Investigate Feats of Engineering, children will gain an appreciation for the important field of engineering as they develop their own building skills.

Andrew Christensen, co-developer (along with the late Neil Jacobson) of Integrative Behavioral Couple Therapy and Brian Doss provide an essential manual for their evidence-based practice. The authors offer guidance on formulation, assessment and feedback of couples' distress from an IBCT perspective. They also detail techniques to achieve acceptance and deliberate change. In this updated edition of the work, readers learn about innovations to the IBCT approach in the 20+ years since the publication of the original edition-including refinements of core therapeutic techniques. Additionally, this edition provides new guidance on working with diverse couples, complex clinical issues and integrating technology into a course of treatment.

Scott Andrew Christensen's debut collection the boundaries of return is a compelling exploration of passage in and through the natural world. Richly symbolic and formally experimental, Christensen's poems create worlds at once uniquely perceptive and recognisable, in patterns of verbal play that are distinctive and memorable. "Scott Andrew Christensen's poetry haunts the borders between the physically detailed and the metaphysically mysterious, or between Nature--in its beautiful details--and the Spirit, what is ineffable... Although the boundaries of return represents a debut, Christensen is already preternaturally skilled in edging toward Wisdom or Faith via witnessing everyday doings and the beings of persons, creatures, and things. Welcome--with joy--the boundaries of return." GEORGE ELLIOT CLARKE

Every couple has disagreements, but what happens when recurring conflicts start to pull your relationship apart? Do you lie awake hoping that your spouse will eventually see things your way, or rehashing the evidence that you're right? Demand some immediate changes--or else? This popular, science-based guide offers powerful solutions for couples frustrated by continual attempts to make each other change. True acceptance may seem difficult to accomplish, but the clear-cut steps and thought-provoking exercises in this book can make it a reality. You'll learn why you keep having the same fights again and again; how to keep small incompatibilities from causing big problems; what communication strategies really work to resolve conflicts; and how to problem-solve and make positive changes--together. Updated throughout with new research, practical tools, and examples, the second edition features a new chapter on mindfulness.
