When the First Edition of this book was written in 1951, the gas turbine was just becoming established as a powerplant for military aircraft. It took another decade before the gas turbine was introduced to civil aircraft, and this market developed so rapidly that the passenger liner was rendered obsolete. Other markets like naval propulsion, pipeline compression and electrical power applications grew steadily. In recent years the gas turbine, in combination with the steam turbine, has played an ever-increasing role in power generation. Despite the rapid advances in both output and efficiency, the basic theory of the gas turbine has remained unchanged. The layout of this new edition is broadly similar to the original, but greatly expanded and updated, comprising an outline of the basic theory, aerodynamic design of individual components, and the prediction of off-design performance. The addition of a chapter devoted to the mechanical design of gas turbines greatly enhances the scope of the book. Descriptions of engine developments and current markets make this book useful to both students and practising engineers.

The phrase "in-the-wild" is becoming popular again in the field of human-computer interaction (HCI), describing approaches to HCI research and accounts of user experience phenomena that differ from those derived from other lab-based methods. The phrase first came to the forefront 20-25 years ago when anthropologists Jean Lave (1988), Lucy Suchman (1987), and Ed Hutchins (1995) began writing about cognition being in-the-wild. Today, it is used more broadly to refer to research that seeks to understand new technology interventions in everyday living. A reason for its resurgence in contemporary HCI is an acknowledgment that so much technology is now embedded and used in our everyday lives. Researchers have begun following suit-decamping from their usability and living labs and moving into the wild; carrying out in-situ development and engagement, sampling experiences, and probing people in their homes and on the streets. The aim of this book is to examine what this new direction entails and what it means for HCI theory, practice, and design. The focus is on the insights, demands and concerns. But how does research in the wild differ from the other applied approaches in interaction design, such as contextual design, action research, or ethnography? What is added by labeling user research as being in-the-wild? One main difference is where the research starts and ends: unlike user-centered, and more specifically, ethnographic approaches which typically begin by observing existing practices and then suggesting general design implications or system requirements, in-the-wild approaches create and evaluate new technologies and experiences in situ(Rogers, 2012). Moreover, novel technologies are often developed to augment people, places, and settings, without necessarily designing them for specific user needs. There has also been a shift in design thinking. Instead of developing solutions that fit in with existing practices, researchers are experimenting with new technological possibilities that can change and even disrupt behavior. Opportunities are created, interventions installed, and different ways of behaving are encouraged. A key concern is how people react, change and integrate these in their everyday lives. This book outlines the emergence and development of research in the wild. It is structured around a framework for conceptualizing and bringing together the different strands. It covers approaches, methods, case studies, and outcomes. Finally, it notes that there is more in the wild research in HCI than usability and other kinds of user studies in HCI and what the implications of this are for the field.

Practical and profound, this guide to discovering a true self behind the "parts" played in everyday life presents the information and inspiration necessary to achieve fulfillment. Often taking a humorous perspective, this work is centered on a belief that the tools we use to deceive ourselves and others are the same tools we need to know ourselves better. Guided meditation is one of a series of practices at the center of this strategy that slowly brings into focus an awareness of life and its possibilities.

"Captain Bucko's Galley Slave Cookbook" should be in the sea bag of every "galley slave" from Finland to Fiji. It contains signature recipes from Ancient Rome, Greece, Portugal, Madagascar, the British Isles, Colonial America and New England, the Deep South, the Caribbean, New Orleans and Cajun Country, the Great Lakes, Latin America, famous river towns, Lake Tahoe, the West Coast, Alaska, the Philippines, and Polynesia; as well as some original recipes from the so-called "Golden Age Of Piracy." But it's also fascinating and entertaining to read the stories behind these dishes, from bordello breakfasts to boiled leather satchels.

Most observers agree that marriage in America has been changing. Some think it is in decline, that the growth of individualism has made it increasingly difficult to achieve satisfying and stable relationships. Others believe that changes, such as increasing gender equality, have made marriage a better arrangement for men as well as women.

Based on two studies of marital quality in America twenty years apart, this book takes a middle view, showing that while the divorce rate has leveled off, spouses are spending less time together--people may be "bowling alone" these days, but married couples are also eating alone. Indeed, the declining social capital of married couples--including the fact that couples have fewer shared friends--combined with the general erosion of community ties in American society has had pervasive, negative effects on marital quality.

At the same time, family income has increased, decision-making equality between husbands and wives is greater, marital conflict and violence have declined, and the norm of lifelong marriage enjoys greater support than ever.

The authors conclude that marriage is an adaptable institution, and in accommodating the vast changes that have occurred in society over the recent past, it has become a less cohesive, yet less confining arrangement.
