Throughout history, wild green vegetables have played a significant role in human diets around the world, coevolving alongside agriculture and changing land use patterns (Wilson, 1990). Wild greens such as purslane (Portulaca oleracea), lambquarters (Chenopodium spp.) and amaranth (Amaranthus spp.), wild ancestors of crop plants, are prehistoric foods that are cultural and nutritional mainstays in many parts of the world including the Arizona-Mexico borderland region. While consumption of these foods is commonplace on the Mexican side of the border, on the American side their use is less frequent. In this study, I explore the patterns of and barriers to consumption of wild green vegetables by Latinos living in the Arizona (AZ)-Mexico (MX) borderland city of Tucson, AZ. I use Weber's rationalization theory, as well as human agency theory, to guide my exploration of how the dominant food system contributes to dietary acculturation and the loss of agency among Latinos living in Tucson. In-depth interviews and naturalistic observations are employed across a diverse array of market settings, which include a farmers' market, several carniceri­as (Mexican butcher shops), a corner store/tortilleria with procurers and purveyors of Latino and indigenous foods, and a more conventional supermarket. The findings reveal a reduction in knowledge and consumption of heritage greens by Latinos concurrent to their adoption of more mainstream American foods. I consider this pattern and its various implications in the context of the rationalization of the dominant U.S. food system, which leads to a dynamic that favors efficiency and productivity over authenticity and aesthetics.

abstract: The purpose of this study is to examine how community-based youth theater ensembles create conditions for youth to practice cultural agency and to develop a sense of themselves as valuable resources in a broader community development process. The researcher employed a qualitative methodology, using a critical and interpretive case study approach which enabled her to document and analyze three community-based youth theaters in New York City: Find Your Light, a playwriting/performance program for youth associated with the NYC shelter system; viBeStages, an all-girl youth ensemble (part of viBe Theater Experience or "viBe"); and Ifetayo Youth Ensemble (IYE), a multi-age ensemble for youth of African descent living in Flatbush and its surrounding neighborhoods (part of Ifetayo Cultural Arts Academy). All three programs are youth-based performing arts ensembles with a mission-driven focus on positive youth development and community building; they are long-term engagements, active in their communities for at least three years; and they are all part of arts organizations that value artistry as their principle means of impacting communities. All of the young artists involved in these programs participated in a sustained process of creating original performance pieces based on stories relevant to their lives and/or the lives of their communities. This dissertation examines how, through their playmaking processes, they began to identify, critique and experiment with commonly held beliefs about human agency and interaction, to activate and embellish the symbolic systems and repertoires that make up their communities, and to practice new ways of coming together. Through their use of artistic practices, the youth developed a sense of themselves as viable shapers of their communities and, in varying degrees, also used other aspects of culture (values, rituals, traditions, aspirations and the arts) to make meaning, contribute, and shape their cultural locations, offering new forms, symbols, structural models and imaginings. / Dissertation/Thesis / Ph.D. Theatre 2010
