In the woods of Massachusetts, pairs of contestants huddle in tents filled with communications equipment. Their voices soar through the air, riding waves into the atmosphere, as they comb through static and noise for a response from the other side of the world. They’re searching for loot—in the form of other voices in the sky. The rarer their contact, the more valuable their treasure. Joining them in their quest is author J. K. George, an experienced radio operator himself, who guides you through the exciting world of amateur radio competition and the intriguing characters of the 2014 World Radiosport Team Championship. The competitors hail from across the planet—from youthful challengers to veterans with decades of radiosporting experience. You will meet fascinating personalities not only among the teams themselves but also among their “widows”—spouses left behind for the allure of the airwaves. They battle computer malfunctions, getting lost, and staying at the top of their game for 24 hours in a hot, stuffy tent. The final scores bring surprises, disappointments, even a recount, and decades-long friendships will be stressed in the fight for the crown of amateur radio—the ultimate “contact” sport.

Faith holds up a photo of the boarded-up, vacant house: "It’s the first thing I see. And I just call it ‘the Homeless House’ ‘cause it’s the house that nobody fixes up." Faith is one of fourteen women living on Syracuse’s Southside, a predominantly African-American and low-income area, who took photographs of their environment and displayed their images to facilitate dialogues about how they viewed their community. A Place We Call Home chronicles this photography project and bears witness not only to the environmental injustice experienced by these women but also to the ways in which they maintain dignity and restore order in a community where they have traditionally had little control. To understand the present plight of these women, one must understand the historical and political context in which certain urban neighborhoods were formed: Black migration, urban renewal, white flight, capital expansion, and then bust. Ducre demonstrates how such political and economic forces created a landscape of abandoned housing within the Southside community. She spotlights the impact of this blight upon the female residents who survive in this crucible of neglect. A Place We Call Home is the first case study of the intersection of Black feminism and environmental justice, and it is also the first book-length presentation using Photovoice methodology, an innovative research and empowerment strategy that assesses community needs by utilizing photographic images taken by individuals. The individuals have historically lacked power and status in formal planning processes. Through a cogent combination of words and images, this book illuminates how these women manage their daily survival in degraded environments, the tools that they deploy to do so, and how they act as agents of change to transform their communities.

Many of us assume that our creative process is beyond our ability to influence, and pay attention to it only when it isn't working properly. For the most part, we go about our daily tasks and everything just "works." Until it doesn't. Adding to this lack of understanding is the rapidly accelerating pace of work. Each day we are face escalating expectations and a continual squeeze to do more with less. We are asked to produce an ever-increasing amount of brilliance in an ever-shrinking amount of time. There is an unspoken (or spoken!) expectation that we'll be accessible 24/7, and as a result we frequently feel like we're "always on." Now business creativity expert Todd Henry explains how to unleash your creative potential. Whether you're a creative by trade or an "accidental creative," this book will help you quickly and effectively integrate new ideas into your daily life.

Materials and mechanical engineering researchers studying wear, fretting, elastic indentation testing and other tribological processes frequently need closed-form solutions for various attributes of contacts. These characteristics include contact law, pressure distribution, internal state of stress induced and the influence of friction. Materials and mechanical engineering researchers studying wear, fretting, elastic indentation testing and other tribological processes frequently need closed-form solutions for various attributes of contacts. These characteristics include contact law, pressure distribution, internal state of stress induced and the influence of friction. These solutions, scattered throughout the applied mechanics literature, are difficult to locate, are presented using a range of solution techniques, and express results in a way that is suitable only for experts in the field. `Mechanics of Elastic Contacts' uses a consistent set of recipes for the solution of all relevant problems, presents results in the simplest possible forms, and contains summaries using tabulated data. This reference source will provide a clear guide to elastic contacts for engineering designers, materials scientists and tribologists irrespective of their level of expertise in this important subject.
