Distorted vowel production is a hallmark characteristic of dysarthric speech, irrespective of the underlying neurological condition or dysarthria diagnosis. A variety of acoustic metrics have been used to study the nature of vowel production deficits in dysarthria; however, not all demonstrate sensitivity to the exhibited deficits. Less attention has been paid to quantifying the vowel production deficits associated with the specific dysarthrias. Attempts to characterize the relationship between naturally degraded vowel production in dysarthria with overall intelligibility have met with mixed results, leading some to question the nature of this relationship. It has been suggested that aberrant vowel acoustics may be an index of overall severity of the impairment and not an "integral component" of the intelligibility deficit. A limitation of previous work detailing perceptual consequences of disordered vowel acoustics is that overall intelligibility, not vowel identification accuracy, has been the perceptual measure of interest. A series of three experiments were conducted to address the problems outlined herein. The goals of the first experiment were to identify subsets of vowel metrics that reliably distinguish speakers with dysarthria from non-disordered speakers and differentiate the dysarthria subtypes. Vowel metrics that capture vowel centralization and reduced spectral distinctiveness among vowels differentiated dysarthric from non-disordered speakers. Vowel metrics generally failed to differentiate speakers according to their dysarthria diagnosis. The second and third experiments were conducted to evaluate the relationship between degraded vowel acoustics and the resulting percept. In the second experiment, correlation and regression analyses revealed vowel metrics that capture vowel centralization and distinctiveness and movement of the second formant frequency were most predictive of vowel identification accuracy and overall intelligibility. The third experiment was conducted to evaluate the extent to which the nature of the acoustic degradation predicts the resulting percept. Results suggest distinctive vowel tokens are better identified and, likewise, better-identified tokens are more distinctive. Further, an above-chance level agreement between nature of vowel misclassification and misidentification errors was demonstrated for all vowels, suggesting degraded vowel acoustics are not merely an index of severity in dysarthria, but rather are an integral component of the resultant intelligibility disorder.

Unauthorized confronts the relationship between technology and personhood in the modern world. More specifically, it addresses the personal and social effects of border politics within the frame of cyber crime. The short film takes place in the near future where a hacker can create citizenship for anyone she wants, effectively turning anyone into a legal person in the United States. This parallels the real life struggles of unauthorized immigrants trying to gain a new life this side of the border despite the overwhelming backlash from the conservative and xenophobic population. The main character's ability to grant citizenship forces the viewer to confront what being a person really means. The film also alludes to the popularized antics of modern day hackers and whistleblowers who are often turned into heroes for fighting the establishment despite their character flaws. The protagonist of Unauthorized struggles through underhanded sexism and blatant racism as well as her own personal struggles with drug addiction and failed relationships. These are very real struggles women face in technology jobs and life in general. The main character's actions ultimately destroy every relationship that she's established, including the connection to her own family. This film, in short, is about the walls people build between each other, both physical and social.

Zoraida Ladrón de Guevarra was born in 1936 in Coyula, Mexico, a small village in the state of Oaxaca. Her father’s passing required Zoraida to find a job at age fourteen to support her family. Her story, a 200-page memoir entitled “After Papa Died,” follows Zoraida’s time as a servant and eventual nanny in Veracruz. Flashing back to memories of her hometown and the people living in it, the story ends before she enters America first as a visitor in 1954, and later on a working Visa in 1957—the first woman in her village to leave to the United States. Hers is a story relevant today, evident with the paradoxes explored between poverty and riches, patriarchy and matriarchy, freedom and captivity. Assimilation impacts the reading of this memoir, as Zoraida began writing the memoir in her 80s (around fifty years after gaining American citizenship). This detailed family history is about the nature of memory, community, and in particular, the experience of being an immigrant. This thesis project centers on this text and includes three components: an edited memoir, informational interviews, and an introduction. Beginning as a diary steeped in the tradition of oral history, the memoir required a “translation” into a written form; chapters and chronological continuity helped with organization. Topics of interest from the story, such as identity, domestic violence, and religion, are further explored in a series of interviews with Zoraida. The inclusion of an introduction to the text contextualizes the stories documented in the memoir with supplemental information. The contents of the project are housed on a website: alongwaybabyproject.net.

The computer classification accuracy of these normalized data were then compared to the results of human perceptual classification accuracy of the actual vowels. These results were then analyzed to determine if these techniques correlated with the human data.

Immigration policy in the United States today is complex and far-encompassing. This project aims to present it in an easily accessible way: Through the eyes of those who have experienced its effects in a deeply personal manner. This online project, housed at http://immigrant-experience.com/, includes profiles of four people who have immigrated to the United States from other countries. The website includes graphics and multimedia elements, that help to tell their stories. It also provides information about immigration statistics, research and policy. The DREAMer who came to the country as a child, the young Mexican man on a seasonal visa, and the Eritrean refugee share in the immigrant experience, but the effects of U.S. policy on their lives are vastly different. Factors at play include age, education, country of origin and socioeconomic status. These factors are what shape the policy that dictates whether an immigrant can become an American citizen. They are also what make Gloria, Adrian and Azarya's stories so unique. It is a multitude of personal stories that collectively define the immigrant experience. These stories may be drastically different, depending on the country of origin and circumstances of each individual, but some aspects of the experience are shared. The difficulties inherent in uprooting oneself from a familiar community are common to "immigrants" of all shapes and sizes: students moving out of state for college, new hires moving to a new city, parents moving their children into a better neighborhood, etc. Through in-depth profiles of immigrants from a wide variety of backgrounds, this project highlights those shared experiences while showing the diversity of personal stories, challenging contemporary stereotypes about immigrant populations.

The purpose of this study is to document and analyze three women's English language learning journeys after moving from various parts of Mexico to Phoenix, Arizona. The study explores the effects of English as a Second Language (ESL) education on the social and cultural development of Mexican women students at Friendly House, whose mission is to "Empower Arizona communities through education and human services". The literature review section explores such topics as the complications and history of Mexican immigration to Phoenix and of state-funded ESL education in Phoenix. The consequent research study will entail a pair of interviews with the three beginner ESL students about their lives in Mexico compared to their lives in Phoenix, with a specific focus on aspects of their language acquisition and cultural adjustment to life in Arizona. Photos of and by the consultants add to their stories and lead to a discussion about the implications of their experiences for ESL teachers. By documenting the consultants' experiences, this study finds many gaps in ESL education in Phoenix. Suggestions about how ESL programs and teaching methods can be modified to fit student's needs form the basis for the conclusions.

In recent years, immigration, especially concerning those individuals immigrating from Central America and Mexico, has become increasingly controversial. Within the last five presidents, policies concerning immigration have shifted. Under President Bill Clinton in 1997, the Flores Settlement, an agreement between immigration activist organizations and the government that created standards for detaining accompanied and unaccompanied minors was made. Following 9/11, in 2005, President George W. Bush increased the amount of money spent on immigration enforcement in an effort to deport more immigrants. President Barack Obama increased the number of deportations from President Bush during his first term. However, in 2014, an already imperfect immigration system was disrupted by an influx of child immigrants. As a result, detention centers were at capacity and unable to accommodate the increasing numbers of immigrants. Child migrants were placed in caged-areas, immigration lawyers and courts quickly became overwhelmed with cases, and children were alone and could barely communicate. This thesis explores the various relationships between accompanied and unaccompanied minors from Central America, the American legal system, and the media and broadcast news outlets’ rhetoric concerning child migrants. Focusing on the ways in which immigrant minors are objectified by the legal system and the framing of immigrants in the media, it is evident that their complex interaction allows for the oppression of the child migrants. Since the American legal system and the media influence and respond to each other, the responsibility of the child migrants’ dehumanization is on both the legal system and the rhetoric of the media and broadcast news outlets.

Daughters of America traces the interviews of six young women who identify as daughters of immigrants and finds common themes across cultures and nationalities. This project hopes to create a sense of home through text by providing a space for an underrepresented group to share their stories and to offer a way for other children of immigrants to feel valid in their experiences.
