Description
The purpose of this study was to investigate critical literacy practices in two prehistoric exhibits in a natural history museum. Bourdieu's habitus and Bakhtin's dialogism served as theoretical frames to collect and analyze data. Data were collected and triangulated using field notes, interview transcriptions, archives, and other data sources to critically scrutinize textual meaning and participant responses. Spradley's (1979) domain analysis was used to sort and categorize data in the early stage. Glaser and Strauss's (1967) constant comparative method was used to code data. My major findings were that museum texts within this context represent embedded beliefs and values that were interwoven with curators` habitus, tastes and capital, as well as institutional policies. The texts in the two Hohokam exhibits endorse a certain viewpoint of learning. Teachers and the public were not aware of the communicative role that the museum played in the society. In addition, museum literacy/ies were still practiced in a fundamental way as current practices in the classroom, which may not support the development of critical literacy. In conclusion, the very goal for critical museum literacy is to help students and teachers develop intellectual strategies to read the word and the world in informal learning environments.

Description
The purpose of this study is to investigate the literacy practices of three members of Alcoholics Anonymous (A.A.) and to explore how they use these practices to support and maintain their recovery in their lives. This study also aims to examine how each participant used specialist language, enacted certain identities and acquired the secondary Discourse in A.A. through literacy use. This dissertation study is the result of in-depth interviewing in which each participant was interviewed three times for 90-minutes. These interviews were then transcribed and analyzed using discourse analysis. Study results are presented in three chapters, each one designated to one of the participants. Within these chapters is a life history (chronology) of the participant leading up to the point in which they got sober. The chapters also include a thematic discourse analysis of the interview transcripts across themes of literacy practice and topics in A.A. A conclusion is then presented to investigate how literacy was used from a sociocultural perspective in the study. Due to the emotionally charged nature of this dissertation, it has been formatted to present the stories of the participants first, leaving the theoretical framework, literature review and research methods to be included as appendices to the main text.

Description
Teachers have the one of the most difficult, yet most rewarding jobs to guide our impressionable youth into academically prepared independent thinkers. This undertaking requires a commitment, as well as an enormous effort that can oftentimes be overwhelming. Teaching has been found to be a stressful profession for several decades with the potential concern of negative consequences for both teachers and students. The purpose of this study was to view mutual influences that affected the stress levels of urban teachers, as well as gather possible solutions to help alleviate some areas of stress. This study evaluated an urban school district in Arizona to uncover existing stressors for elementary teachers. Through qualitative analysis, this study utilized focus group interviews within this urban district, which consisted of 20 teachers in various grade levels. Four to five teachers formed each focus group, where participants responded to six open-ended questions in a candid setting. Using the grounded theory, major and minor themes emerged as a result of teacher responses that revealed trends and commonalities. Additionally, participants relayed their suggestions to mitigate some of these stressors. This study revealed that the some of the stressors that surfaced were common to the entire group, while some grade level subgroups differed in areas of stress. The suggestion to implement purposeful support systems to improve the stress of teachers was recommended with the proposal to reexamine the results for their effectiveness in future studies.

Description
ABSTRACT This mixed methods study examines 126 community college students enrolled in developmental reading courses at a mid-sized Southwestern community college. These students participated in a survey-based study regarding their reading experiences and practices, social influence upon those practices, reading sponsorship, and reading self-efficacy. The survey featured 33 structured response prompts and six free response prompts, allowing for both quantitative and qualitative analysis. The study¡&brkbar;s results reflected the diverse reading interests and practices of developmental college students, revealing four main themes: -the diversity and complexity of their reading practices; -the diversity in reading genre preferences; -the strong influence of family members and teachers as reading sponsors in the past with that influence shifting to friends and college professors in the present; and, -the possible connection between self-efficacy and social engagement with reading. Findings from this study suggest these college students, often depicted as underprepared or developmental readers, are engaging in diverse and sophisticated reading practices and perceive reading as a means to achieve their success-oriented goals and to learn about the real world.This study adds to the limited field of community college literacy research, provides a more nuanced view of what it means to be an underprepared college reader, and points to ways community college educators can better support their students by acknowledging and building upon their socio-culturally influenced literacy practices. At the same time, educators can advantage students academically in terms of building their cultural capital with overt inculcation into disciplinary literacies and related repertoires of practice. Keywords: college students, reading, sponsorship, multimodal reading practices, developmental education, social networking, and literacy

Description
This dissertation shares findings from a yearlong qualitative case study of Young Voices Rise (YVR), a diverse spoken word poetry group in the urban Southwest. The study examined the group's characteristics and practices, adolescent members' views of their writing and themselves as writers, and changes members attributed to their experiences in YVR. Data sources included interviews with six adolescent poets and two adult teaching artists, observations of writing workshops and poetry slams, collection of group announcements through social media, and collection of poems. Sociocultural theory guided the study's design, and grounded theory was used to analyze data. This study found that YVR is a community of practice that offers multiple possibilities for engagement and fosters a safe space for storytelling. The adolescent participants have distinct writing practices and a strong sense of writing self; furthermore, they believe YVR has changed them and their writing. This study has several implications for secondary English language arts. Specifically, it recommends that teachers build safe spaces for storytelling, offer spoken word poetry as an option for exploring various topics and purposes, attend to writers' practices and preferences, encourage authentic participation and identity exploration, and support spoken word poetry school-wide.

ABSTRACT
The purpose of this study is to explore how LDS (Mormon) fans of Stephenie Meyer's Twilight saga make meanings from the text in the blogging community known as the Bloggernacle. It investigates how fans recognize, reflect, reinterpret, and resist meanings surrounding multiple Big "D" Discourses (Gee, 1999/2010; 2011) in and around the text. It examines the ways in which LDS fans (Church of Jesus Christ of Latter-day Saints) of the Twilight saga use language in order to signify membership in a particular Discourse. In addition, it seeks to understand how LDS fans use language to perform various identities and position themselves and others within the digital space.
This dissertation study analyzes the threads of five blogs and three discussion forums using the combined methods of critical ethnography (Carspecken, 1996) and Gee's (1999, 2010;2011) discourse analysis. It concludes, that, while multiple Discourses are present within the conversational threads, mainstream Mormon Discourse remains dominant and normalized within the space, which both informs and limits the interpretations available to Mormon fans. In addition, identity performance is negotiated in the blogs, and members form specific sub-communities within the Bloggernacle so as to create a space for those with distinct ways of believing, valuing, knowing, and identifying.

Description
In accordance with the Principal Agent Theory, Property Right Theory, Incentive Theory, and Human Capital Theory, firms face agency problems due to “separation of ownership and management”, which call for effective corporate governance. Ownership structure is a core element of the corporate governance. The differences in ownership structures thus may result in differential incentives in governance through the selection of senior management and in the design of senior management compensation system. This thesis investigates four firms with four different types of ownership structures: a public listed firm with the controlling interest by the state, a public listed firm with a non-state-owned controlling interest, a public listed firm a family-owned controlling interest, and a Sino-foreign joint venture firm. By using a case study approach, I focus on two dimensions of ownership structure characteristics – ownership diversification and differences in property rights so as to document whether there are systematic differences in governance participation and executive compensation design. Specifically, I focused on whether such differences are reflected in management selection (which is linked to adverse selection and moral hazard problems) and in compensation design (the choices of performance measurements, performance pay, and in stock option or restricted stock). The results are consistent with my expectation – the nature of ownership structure does affect senior management compensation design. Policy implications are discussed accordingly.

Description
Many educators believe that the path to a better future is a college education. Initiatives that promote college-going cultures are quite commonplace in many public high schools with some offering elective college-prep support programs like Advancement Via Individual Determination (AVID). Yet, certain groups of students are not taking advantage of these opportunities. In the initial AVID sections at a metropolitan high school in the American Southwest, the girls out-numbered the boys 2:1, and the Hispanic girls outnumbered the Hispanic boys by almost 3:1. The purpose of this study was to uncover some of the factors that influenced five Hispanic males' participation, or lack thereof, in AVID, and the ways in which those factors connected to their masculine identities. What the participants say about what influenced them to be involved, or not, in the program is reported. Some themes revealed in the interviews include how the participants' scholar identity is connected to their masculine identity, how they balance their "coolness" quotient with their desires to achieve academic success, how they depend on personal relationships and collaboration, and how their families and communities have influenced them. This information may lead to the development of strategies that will increase future representation of Hispanic males in similar programs.

Description
The theme for this work is the development of fast numerical algorithms for sparse optimization as well as their applications in medical imaging and source localization using sensor array processing. Due to the recently proposed theory of Compressive Sensing (CS), the $\ell_1$ minimization problem attracts more attention for its ability to exploit sparsity. Traditional interior point methods encounter difficulties in computation for solving the CS applications. In the first part of this work, a fast algorithm based on the augmented Lagrangian method for solving the large-scale TV-$\ell_1$ regularized inverse problem is proposed. Specifically, by taking advantage of the separable structure, the original problem can be approximated via the sum of a series of simple functions with closed form solutions. A preconditioner for solving the block Toeplitz with Toeplitz block (BTTB) linear system is proposed to accelerate the computation. An in-depth discussion on the rate of convergence and the optimal parameter selection criteria is given. Numerical experiments are used to test the performance and the robustness of the proposed algorithm to a wide range of parameter values. Applications of the algorithm in magnetic resonance (MR) imaging and a comparison with other existing methods are included. The second part of this work is the application of the TV-$\ell_1$ model in source localization using sensor arrays. The array output is reformulated into a sparse waveform via an over-complete basis and study the $\ell_p$-norm properties in detecting the sparsity. An algorithm is proposed for minimizing a non-convex problem. According to the results of numerical experiments, the proposed algorithm with the aid of the $\ell_p$-norm can resolve closely distributed sources with higher accuracy than other existing methods.

Description
The positive relationship between self-regulation and student achievement has been repeatedly supported through research. Key considerations that have resulted from prior research include instructor feedback and explicit expectations, student perception of their control of their progress, accurate self-calibration, reflection, goal-setting, age, and methods by which a cycle which integrates all of these can be put in place. While research provides evidence for that fact that it is possible to support student success in several of these areas, many questions are left as to how guided, active self-regulation impacts students perception of their control over their performance, their ability to accurately assess and act upon their strengths and weaknesses, and, ultimately, their overall progress at different developmental stages. This study intended to provide a better understanding of how guidance in the self-regulation strategies of sixth grade science students can impact their attitudes toward learning. Specifically, this study investigated the question, "What is the effect of active reflection, graphing of grades, and goal setting on sixth-grade students' locus of control and ability to self-regulate?"
