This dissertation is primarily focused on the topic of M dwarf metallicities and their relevance to the study of extrasolar planets. I begin by describing a method for accurately determining M dwarf metallicities with spectral synthesis based on abundance analyses of visual binary stars. I then apply this technique and present the first spectroscopic metallicities of three M dwarfs with planetary mass companions. The three M dwarf planet hosts have sub-solar metallicities, a surprising departure from the trend observed in FGK-type planet hosting stars. I discuss the implications of this result for extrasolar planet searches around the most numerous stars in the galaxy. I also present measured metallicities for a select group of M dwarfs with precisely determined masses and luminosities. Comparison of these stars' V band magnitudes with the predictions of the current state-of-the-art theoretical models for low-mass stars indicate that the models are deficient, as previously thought. I discuss how the cool star model atmospheres that were developed for the metallicity analysis technique might be used to improve M dwarf structure and evolution models. In addition to M dwarf metallicities, I describe some complementary work to determine the true mass of an extrasolar planet candidate using a combined analysis of high-precision astrometry and radial velocities. I present a dynamical mass for the companion to HD 33636 that indicates it is a low-mass star instead of an exoplanet. This result demonstrates the value of follow-up astrometric observations to determine the true masses of exoplanet candidates detected with the radial velocity method. Finally, I discuss the broader implications of the results presented in this dissertation and the prospect for similar work in the future.

This action research between the researcher and three urban public school teachers examines the language learning process of three focal students producing written academic English. This study addresses the challenges that students encounter in learning written academic English and influences on the teachers' pedagogical decisions by their assessment of students' oral and written language patterns in an attempt to raise the level of written academic English in the students' writing. It seeks to answer when an African American student uses African American Vernacular in his/her oral and written language, what impact if any this has on the African American student's writings, and what changes occur in the student's perception of himself as a writer because teachers are often frustrated by raising the quality of writing using written academic English. It also seeks to discover how to support language learning for African American students as well as other non-dominant language students. The methods for collecting data consist of participant-observation, semi-structured interviews, student-produced artifacts, and field notes. The study has implications for how written academic English can be effectively taught using components of balanced literacy in urban schools.

"Poetry 'n Acts: The Cultural Politics of Twentieth-Century American Poets' Theater," focuses on the disciplinary blind spot that obscures the productive overlap between poetry and dramatic theater and prevents us from seeing the cultural work that this combination can perform. Why did 2100 people turn out in 1968 to see a play in which most of the characters speak only in such apparently nonsensical phrases as "Red hus the beat trim doing going" and "Achtung swachtung"? And why would an Obie award-winning playwright move to New Jersey to write such a play in the first place? What led to the founding in 1978 of the San Francisco Poets Theatre by L=A=N=G=U=A=G=E writers, and why have those plays and performers been virtually ignored by critics despite the admitted centrality of performance to L=A=N=G=U=A=G=E writing's textual politics? Why would the renowned Yale Repertory Theatre produce in the 1990s the poetic, plotless plays of a theater newcomer twice in as many years---even when audiences walked out? What vision for the future of theater could possibly involve episodic drama with footnotes? In each example, part of the story is missing. This dissertation begins to fill in that gap. Attending to often overlooked aspects of theater language, this dissertation examines theatrical performances that use poetic devices to intervene in narratives of cultural oppression, often by questioning the very suitability of narrative as a primary means of social exchange. While Gertrude Stein must be seen as a forerunner to contemporary poets' theater, chapter one argues that the Living Theatre's late 1950s and early 1960s anti-authoritarian theater demonstrates key alliances between poetry and theater at mid-century. The remaining chapters closely examine particular instances of poets' theater by Amiri Baraka (known equally as poet and playwright), Carla Harryman (associated with West Coast poetry), and Suzan-Lori Parks (a critically acclaimed playwright). These productions put poetic theater on the backs of tractors in Harlem streets, in open gallery spaces, and in more conventional black box and proscenium architectures, and each case develops the importance of performance contexts and production histories in determining plays' cultural effects.

Extracting relevant low-dimensional information from high-dimensional data is a common pre-processing task with an extensive history in Statistics. Dimensionality reduction can facilitate data visualization and other exploratory techniques, in an estimation setting can reduce the number of parameters to be estimated, or in hypothesis testing can reduce the number of comparisons being made. In general, dimension reduction, done in a suitable manner, can alleviate or even bypass the poor statistical outcomes associated with the so-called "curse of dimensionality.''. Statistical models may be specified to guide the search for relevant low-dimensional information or "signal'' while eliminating extraneous high-dimensional "noise.'' A plausible choice is to assume the data are a mixture of two sources: a low-dimensional signal which has a non-Gaussian distribution, and independent high-dimensional Gaussian noise. This is the Non-Gaussian Components Analysis (NGCA) model. The goal of an NGCA method, accordingly, is to project the data onto a space which contains the signal but not the noise. We conduct a comprehensive review of NGCA. We analyze the probabilistic features of the NGCA model and elucidate connections to similar well-known models and methods in the literature, including a hitherto-unseen and surprising connection to a set of models proposed by Cook in the context of dimension-reduction in regression. We review the literature on NGCA, catalogue existing NGCA methods, and compare them to the method proposed in Chapter 2. We also propose and analyze a new NGCA method based on characteristic functions called CHFNGCA. We show CHFNGCA is, under mild moment conditions on the non-Gaussian sources, consistent and asymptotically normal; the latter property has not been demonstrated for any other NGCA method in the literature. We conclude by highlighting areas for future work. The proof of all stated propositions, lemmas and theorems are contained in Appendices A and B.

Policing the borders of identity at The Mormon Miracle Pageant (Utah, Joseph Smith)

While Mormons were once the "black sheep" of Christianity, engaging in communal economic arrangements, polygamy, and other practices, they have, since the turn of the twentieth century, modernized, Americanized, and "Christianized." While many of their doctrines still cause mainstream Christians to deny them entrance into the Christian fold, Mormons' performance of Christianity marks them as not only Christian, but as perhaps the best Christians. At the annual Mormon Miracle Pageant in Manti, Utah, held to celebrate the origins of the Mormon founding, Evangelical counter-Mormons gather to distribute literature and attempt to dissuade pageant-goers from their Mormonism. The hugeness of the pageant and the smallness of the town displace Christianity as de facto center and make Mormonism the central religion. Cast to the periphery, counter-Mormons must attempt to reassert the centrality of Christianity. Counter-Mormons and Mormons also wrangle over control of terms. These "turf wars" over issues of doctrine are much more about power than doctrinal "purity": who gets to authoritatively speak for Mormonism. Meanwhile, as Mormonism moves Christianward, this creates room for Mormon fundamentalism, as small groups of dissidents lay claim to Joseph Smith's "original" Mormonism. Manti is home of the True and Living Church of Jesus Christ of Saints of the Last Days, a group that broke away from the Mormon Church in 1994 and considers the mainstream church apostate, offering a challenge to its dominance in this time and place.

At University counseling centers, 20% to 25% of the students who complete an initial "intake" appointment choose to not return for recommended further services. This is a significant problem that merits more research attention. Most of the extant studies have been quantitative investigations examining clinic, client, and therapist variables. For the most part, findings have been mixed; however, minority racial status, low education, and low SES have been significantly related to psychotherapy dropout. Few studies have used a qualitative approach to focus on the perspectives of clients who choose to not continue counseling following an initial "intake" appointment. Those that have been done are limited by superficial interviews and fixed-choice questions. To date, no published research has exclusively focused on using in-depth interviews to discover and understand the perspectives of these clients. The purpose of this study was to use qualitative methods to develop a rich understanding of the perspectives and experiences of multiculturally diverse college students who sought initial services at a university counseling center. Because it was discovery oriented with a goal of capturing student perspectives, a qualitative approach was an appropriate choice. The study included students in moderate-to-high psychological distress who attended an initial "intake" session and focused on students who chose to not return for recommended individual counseling. Maximum variation sampling at a large, midwestern university made it possible to recruit a multiculturally diverse sample of nineteen students who varied widely across age, race/ethnicity, gender, and citizenship status. In addition, the nineteen student-therapist intake dyads were also quite varied due to the diverse staff at the counseling center. Nineteen initial and five follow-up individual, audiotaped interviews were completed and transcribed by the researcher. A rigorous inductive analysis of the data yielded five major findings that are connected by a common thread: a need to better understand and appreciate student perspectives. This research facilitated an important shift in my perspective from that of an "insider" (therapist) to that of an "outsider" (student coming to the counseling center). The five major findings are grounded in these students' experiences and reflect their perspectives on coming to counseling: (a) It is difficult for students to come to counseling and they put off coming. (b) "Insider" and "outsider" understandings of the intake process and counseling center practices differ. It's important for therapists and centers to critically question unspoken assumptions about student understandings. (c) By the time they do come in, students are ready to start the process of counseling. They want that initial "intake" visit to be a beginning, not a simple screening. (d) Students know if they have therapist preferences and it can be empowering to let them voice those preferences. (e) Effectively negotiating difference with cultural empathy is especially important in the initial "intake" session. Recommendations, grounded in these findings, are offered as a guide. The underlying goal of these suggestions is to enumerate ways to enhance our practice so that all students' initial experiences at counseling centers might be a little bit better. Quite possibly, such changes could reduce the poor return rate following intake at university counseling centers.

The overarching purpose of this study was to investigate the efficacy of two online modules, comprising part of a coaching leadership course, in achieving the course objectives as defined by key stakeholders. In addition the study aimed to examine coaches' opinions regarding the ease and effectiveness of an online learning environment. This was accomplished in three phases. First, in Phase One the researcher conducted qualitative interviews with key stakeholders to identify the outcomes and objectives of the intervention broadly, and of two of the online modules, specifically. The second phase aimed to examine the effectiveness of the two online modules in increasing knowledge, intended use, and actual use of material covered in the modules. Due to unforeseen circumstances in obtaining and retaining a large enough control or comparison group, a single group longitudinal design had to be employed in Phase Two. Phase three was designed to examine the intervention group coaches' perspectives regarding the ease and utility of the online video format. The stakeholders in Phase One reported that their program goals were of both a macro and micro nature. For example, they hoped that the coaches would, on a macro level: develop a broader awareness of all that their coaching role includes, approach the coaching role similar to that of a CEO, be willing to reflect on their strengths and weaknesses, etcetera. On a micro level, for example, the Phase One participants hoped that the coaches would: improve communication skills, develop a vision for their program, and bring in assistant coaches or interns to supplement their weaknesses. In Phase Two, causality determinations were limited, however, results indicated that the online modules effectively increased knowledge and intended use of the material covered. Finally, Phase Three demonstrated that the coaches perceived that the online modules met their needs, were easy to use, and were an effective way of delivering that style of leadership content.
