Some Type of Way: Aging out of Foster Care seeks to address the following questions currently relevant to practitioners, policymakers, and researchers: What are the realities of the lives of youth aging out? Why are they struggling? What are agencies and service providers doing to help them? What should be done to help these youth negotiate the transitions out of care and into adulthood? Based on over 90 interviews and almost 1,000 hours of observation of youth aging out and service providers in a mid-Atlantic county in the United States, the book presents real stories along with relevant research and theories to help understand how youth transition out of foster care and into adulthood. Featuring five youth--Plato, Solana, Titi, Matty, and Jaden--and including poignant examples from many others--the book explores the complex and complicated challenges youth face as well as their creative survival strategies and resilience. The book includes descriptions of service providers' efforts t

A beautifully illustrated poetry gift book about making the most of the time we haveA classic poem with a timeless message, presented in a small and beautiful gift book.Rose Milligan never intended to publicly share her poem 'Dust If You Must', but a series of events led her to publish it in The Lady magazine in 1998. Her charming message about what we value in life resonated with audiences, and it has since been read on BBC radio, posted on Instagram, printed on tea towels, read at funerals and put to music.Now appearing as a book for the first time, beautifully illustrated throughout by illustrator Hayley Wells, Dust If You Must is a timeless reminder to focus on the things we can enjoy in the world, rather than the things we think we need to do.

Now in paperback.Libby comes from a long line of bullies. She wants to be different, but sometimes that doesn’t work out. To bolster herself, she makes a card with the message You are amazing. That card sets off a chain reaction that ends up making a difference in the lives of some kids who could also use a boost―be it from dealing with bullies, unaccepting families, or the hole that grief leaves. Receiving an encouraging message helps each kid summon up the thing they need most, whether it’s bravery, empathy, or understanding. Because it helps them realize they matter―and that they're not flying solo anymore.

An illustrated study of the early-generation jet, the F2H Banshee, a frontline aircraft that served with US Navy, US Marine Corps squadrons and Royal Canadian Navy (RCN) squadrons.The F2H Banshee was an extraordinarily successful early-generation jet that outlasted both contemporary and more modern fighter types on the decks of the US Navy’s aircraft carriers in the 1950s. It served in a variety of roles, undertaking fighter, strike fighter, night-fighter, nuclear strike, and photo-reconnaissance missions. The Banshee was a frontline aircraft for more than a decade in an era when jet fighters came and went with relatively short service careers. This volume examines the entire service life of the F2H in the service of the US Navy, US Marine Corps, and the RCN. Initially created as a replacement aircraft for McDonnell’s pioneering FH1 Phantom, the F2H served in the Korean War as a strike fighter, close air support aircraft, B29 escort, and photoreconnaissance aircraft, including the latt

A textbook that uses a hands-on approach to teach principles of programming languages, with Java as the implementation language.This introductory textbook teaches the principles of programming languages by using an experiential learning style, in which students learn about language features by realizing those features in a pedagogical compiler. Students use Java―the most commonly used programming language in the first two years of the computer science curriculum―as the implementation language throughout. The book also discusses a range of emerging topics in programming languages missing from existing textbooks, including concurrency, Big Data, and event-driven programming. The goal is to prepare students to design, implement, analyze, and understand both domain-specific and general-purpose programming languages. The book first develops basic concepts in languages, including means of computation using primitive values, means of combination such as variable definition and functions, an

If sex is an truth-teller, Eve is waiting to be found out.On an evening when Eve –a young, queer woman in Brooklyn– is feeling particularly impulsive, she posts some nude photos of herself online.This is how Eve meets Olivia, and through Olivia, the charismatic Nathan – and it’s not long before the three begin a relationship that disturbs as much as it delights her. But to whom is Eve responsible? And to what extent do our desires determine who we are?Acts of Service is a provocatively uncompromising debut of sex and sexuality. As incisive as it is exhilarating, it’s a novel that asks us to face our ideas about desire and power: what we bring to sex, the forces that shape it, and how we find ourselves in intimacy.

In this commentary, David deSilva approaches Ephesians as Paul's contribution to the ongoing work of forming his converts' individual and collective identity in Christ through the celebration of God's activity (past, ongoing, and future) on behalf of all who had responded in trust and faithfulness toward Jesus throughout the eastern Roman empire. He explores how Paul's first-century audiences in Roman Asia would have understood and responded to his message, particularly his promotion of the attitudes, pursuits, and practices that would constitute an appropriate response of gratitude for so costly a deliverance and so magnificent a destiny. deSilva's discussion is richly grounded in the Jewish and Greco-Roman contexts that both informed Paul as he composed and his audiences as they engaged his message. He is also attentive to points of relevance to the modern contexts of today's readers who continue to wrestle with Paul's vision for Christian discipleship and human community.

Functional and concurrent programming paradigms can help experienced object-oriented developers write high-quality software faster: code that's easier to understand, debug, optimize, and evolve. But these approaches have often been surrounded by mystification and misconceptions, leading many developers to avoid them. In Functional and Concurrent Programming, Michel Charpentier clears away the confusion, showing how to use these features safely and well, so you can gain their benefits without their pitfalls. Writing for developers with some object-oriented experience in Java, C++, C#, Python, or elsewhere, Charpentier teaches key concepts through the use of realistic, modern examples: code written in Scala, but relevant to users of any modern object-oriented language. As a hybrid language, Scala can be used effectively to illustrate both object-oriented and functional programming; it offers advanced features for concurrency; and it interoperates with Java, and can use many components of

High-flying history is brought to life in this suspenseful story of an unknown and daring pilot named Jack Knight, who in 1921 flew his biplane straight into a blizzard over America's heartland and saved the US Air Mail Service in the process. When Jack Knight takes off in his biplane from North Platte, Nebraska, in 1921, hundreds of people crowd the airstrip. Is Jack transporting a famous passenger? Is he ferrying medicine for a sick child? Nope--Jack has six sacks of mail.For the past few years, biplanes like Jack's have been flying the mail only during daylight hours. Flying after dark is risky and crashes are too common, so lawmakers decide to cut funding for the US Air Mail Service. Outraged officials and pilots want to prove that flying the mail is best, so they concoct a plan--a coast-to-coast race.But when a crash, exhaustion, and a snowstorm ground three of the planes, Jack Knight becomes the race's only hope. All he has to do is fly all night long, leaning out of the plane to
