Many of the scholars that have chronicled the creation of the modern American kitchen have written about how the technological, societal, and cultural revolutions of the twentieth century played a role in dramatically changing its structure and design. More recently, some scholarly research has focused on the evolution of the kitchen and its meaning over time. In several of these research publications scholars profess that the modern American kitchen, more than any other room, has come to symbolize the center or heart of the home, and the warmest room in the house. However, they are quick to acknowledge that, at the beginning of the twentieth century, the kitchen was not so fondly regarded. Little research exists regarding why individuals increasingly became attached to the kitchen or how that attachment influenced the layout, size, objects, and activities conducted in the kitchen. This thesis fills this void by exploring the implications of place attachment on the evolution of the American kitchen from 1901 through 1964. By approaching this research from a combination of design history and environmental psychology, this thesis provides a new perspective to our understanding of the evolution of kitchen design. Using this two-pronged approach, this study contributes to our understanding of the evolution of the kitchen. This study traces the evolution of the modern American kitchen using two qualitative methodologies: material culture and phenomenology. Drawing from a variety of floor plans, advertisements, and articles contained in the House Beautiful magazine 1901 through 1964, as well as writings from popular domestic advisors of the period, this thesis charts the transformation of the modern American kitchen from a "hell on earth" into the "heart and soul of the home." By combining place attachment theory and kitchen design research this thesis provides interior designers new insight into designing kitchens that foster endearing emotional attachment for our clients.

Mid-Century ranch house architecture and design is significant to the architectural landscape of the Phoenix Metropolitan Area. The increasing age of the city's post-WWII properties is creating a need for renovation and rehabilitation, and new technologies have created modern conveniences for today's homeowners, changing interior space plan requirements. These homeowners will need guidance to alter these properties correctly and to preserve the home's essential features. This thesis analyzes the design trends and materials used during the mid-twentieth century, and demonstrates methods for applying them to a current renovation project. The research outlined in this document proves that it is possible to maintain historic integrity, include "Green" design strategies, and apply contemporary technology to a modern ranch renovation.

The Grand Canyon is one of the most well-recognized natural features in the world, but it is also a cultural landscape. The way that the interpretation of this natural and cultural landscape has changed over time reveals a great deal about what values Americans place on scenic areas (especially national parks), how they want to experience them, what stories they want to be told there, and what cultural values were important in America at the time. This dissertation traces how the interpretation of Grand Canyon has changed over time from its earliest history until the present day, particularly focusing on National Park Service (NPS) interpretation of the site. It argues that the process involved in developing NPS interpretation at Grand Canyon National Park involved give and take between the local and national levels of the NPS, but also relied heavily on public engagement and interests. It also explores two sub themes, examining the degree to which Native American perspectives have been incorporated into Grand Canyon National Park interpretation, and how important individual personalities have been in shaping interpretation at the Park. Ultimately, the dissertation reveals that interpretation was a complex act, based upon dynamic interrelationships between author and audience, between professional objectives and public and private pressures, and between what messages the NPS wanted to convey and what visitors told the NPS they wanted to hear.
