Description
Lexical diversity (LD) has been used in a wide range of applications, producing a rich history in the field of speech-language pathology. However, for clinicians and researchers identifying a robust measure to quantify LD has been challenging. Recently, sophisticated techniques have been developed that assert to measure LD. Each one is based on its own theoretical assumptions and employs different computational machineries. Therefore, it is not clear to what extent these techniques produce valid scores and how they relate to each other. Further, in the field of speech-language pathology, researchers and clinicians often use different methods to elicit various types of discourse and it is an empirical question whether the inferences drawn from analyzing one type of discourse relate and generalize to other types. The current study examined a corpus of four types of discourse (procedures, eventcasts, storytelling, recounts) from 442 adults. Using four techniques (D; Maas; Measure of textual lexical diversity, MTLD; Moving average type token ratio, MATTR), LD scores were estimated for each type. Subsequently, data were modeled using structural equation modeling to uncover their latent structure. Results indicated that two estimation techniques (MATTR and MTLD) generated scores that were stronger indicators of the LD of the language samples. For the other two techniques, results were consistent with the presence of method factors that represented construct-irrelevant sources. A hierarchical factor analytic model indicated that a common factor underlay all combinations of types of discourse and estimation techniques and was interpreted as a general construct of LD. Two discourse types (storytelling and eventcasts) were significantly stronger indicators of the underlying trait. These findings supplement our understanding regarding the validity of scores generated by different estimation techniques. Further, they enhance our knowledge about how productive vocabulary manifests itself across different types of discourse that impose different cognitive and linguistic demands. They also offer clinicians and researchers a point of reference in terms of techniques that measure the LD of a language sample and little of anything else and also types of discourse that might be the most informative for measuring the LD of individuals.

Description
The purpose of this study was to examine the attitudes and opinions of Navajo students toward the Navajo language and culture programs within the schools they were attending. Although in the final year of the No Child Left Behind, a majority of the 265 schools on and near the Navajo reservation have not been making Adequate Yearly Progress, a concern for the parents, teachers, administrators, school board members, and the Navajo Nation. The study entailed conducting a survey at five schools; three of which were not meeting the requirements of the No Child Left Behind. The purpose of the survey instrument (27 questions) administered to the students at the five schools was to examine their attitudes and opinions as to participating in Navajo language and culture programs, to determine if the programs assisted them in their academic achievements, and to examine whether these programs actually made a difference for schools in their Adequate Yearly Progress requirement Approximately 87% of 99 Navajo students, 55 boys and 58 girls, ages 9 through 14, Grades 3 through 8, who lived off the reservation in Flagstaff, Arizona and Gallup, New Mexico, and took the survey knew and spoke Navajo, but less fluently and not to a great extent. However, the students endorsed learning Navajo and strongly agreed that the Navajo language and culture should be part of the curriculum. Historically there have been schools such as the Rock Point Community School, Rough Rock Demonstration School, Borrego Pass Community School, and Ramah Community School that have been successful in their implementation of bilingual programs. The question presently facing Navajo educators is what type of programs would be successful within the context of the No Child Left Behind federal legislation. Can there be replications of successful Navajo language and culture programs into schools that are not making Adequate Yearly Progress?

Description
In order to adapt to a new culture and new language, children of immigrant families are faced daily with the responsibility of being the intermediaries between the family and the host culture through their language proficiency (Weisskirch & Alva, 2002). This thesis looks into the experiences of English-Spanish bilingual children as they bridge the gap between the family and the non-Spanish speaking community through their interpreting/translating skills. With an emphasis on children of Mexican-origin, the goal is to further understand and illuminate how these children manage this communication in an adult society, their feelings and thoughts about their experiences, and the child's perceptions about the influence that this experience may or may not have on their future. A sample of seventeen children agreed to participate in a semi-structured face-to-face interview to share their experiences. The data from these interviews were analyzed using a thematic analysis approach (Braun & Clarke, 2006). A priori themes of circumstantial bilingual and adaptive parentification were the initial focus of the research while being open to emerging themes. The children's accounts of their experiences indicated primarily that the Mexican-origin values of familism and respeto (respect) were a significant influence on them when they interpreted/translated for their family. With these traditional cultural values and norms as the groundwork, the sub-themes of normalcy and stress emerged as supportive elements of the circumstantial bilingual experience. Furthermore, the theme of adaptive parentification and the sub-themes of choice, expectation/responsibility to assist, and equality to parents offered further insight on how adaptive parentification can result as the roles of these children change. There was an emergent theme, identity negotiation, which increases our understanding of what the circumstantial bilingual child encounters as the attempt is made to negotiate his identity as an individual who has to mediate language between two opposing cultures. Due to the language brokering responsibility that are bestowed upon these children, it is concluded that communicative support by the parents is a necessary component of the parent-child relationship in order to nurture and develop these children as they negotiate and create their identity to become the successful leaders of tomorrow.

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
This study investigates the effectiveness of the use of Concept-Based Instruction (CBI) to facilitate the acquisition of Spanish mood distinctions by second semester second language learners of Spanish. The study focuses on the development of Spanish mood choice and the types of explanations (Rule-of-Thumb vs. Concept-based) used by five students before and after being exposed to Concept-Based Instruction regarding the choice of Spanish mood following various modalities .The students in this study were presented with a pedagogical treatment on Spanish mood choice that included general theoretical concepts based on Gal'perin's (1969, 1992) didactic models and acts of verbalization, which form part of a Concept-Based pedagogical approach. In order to ascertain the effectiveness of the use of concept-based tools to promote the ability to use Spanish mood appropriately over time, a pre and post-test was administered to the group in which students were asked to respond to prompts containing modalities that elicit the indicative and subjunctive moods, indicate their level of confidence in their response, and verbalize in writing a reason for their choice. The development of these abilities in learners exposed to CBI was assessed by comparing pre and post-test scores examining both forms and explanations for the indicative and subjunctive modality prompts given. Results showed that students continued to rely on Rule-of-Thumb explanations of mood choice but they did expand their use of conceptually-based reasoning. Although the quantitative and qualitative analyses of the results indicate that most students did improve their ability to make appropriate mood choices (forms and explanations) after the CBI treatment, the increased use of conceptually-based explanations for their mood choices led to both correct and incorrect responses.

Description
There have been various studies on the pronunciation of the /s/ in Latin American Spanish. Most studies have shown three variants of the /s/ in syllable-final context: [s] (sibilant), [h] (aspiration) and [ø] (deletion). Most studies focused on Caribbean Spanish, i.e. the Spanish spoken in Puerto Rico, Cuba, the Dominican Republic, and the coasts of Colombia and Venezuela. In Caribbean Spanish, maintaining the /s/ is considered prestigious, aspiration is considered neutral, and deletion of the /s/ is stigmatized (Lafford 1982, 1989). Most people who maintain the /s/ are highly educated people, while people who received little to no education are more likely to delete the /s/ (Lafford 1982, 1989). Besides Caravedo (1990), there have been very few studies on the pronunciation of the /s/ in Peruvian Spanish. To find out more, I analyzed television interviews with Jaime Bayly, a well-known writer and journalist from Lima, Peru to determine when the /s/ is maintained and when it is aspirated or deleted. While watching eight interviews with people of different backgrounds, I recorded what Bayly said, focusing on how he pronounced final-syllable (s). After recording the occurrences of the /s/ and classifying and coding the variables, I used Goldvarb X to establish the probabilistic strength of the proposed factors. The results showed that the most significant linguistic factor was the position of the (s) and the most significant social factors were the gender and acquaintance of the interviewee.

Description
Students may use the technical engineering terms without knowing what these words mean. This creates a language barrier in engineering that influences student learning. Previous research has been conducted to characterize the difference between colloquial and scientific language. Since this research had not yet been applied explicitly to engineering, conclusions from the area of science education were used instead. Various researchers outlined strategies for helping students acquire scientific language. However, few examined and quantified the relationship it had on student learning. A systemic functional linguistics framework was adopted for this dissertation which is a framework that has not previously been used in engineering education research. This study investigated how engineering language proficiency influenced conceptual understanding of introductory materials science and engineering concepts. To answer the research questions about engineering language proficiency, a convenience sample of forty-one undergraduate students in an introductory materials science and engineering course was used. All data collected was integrated with the course. Measures included the Materials Concept Inventory, a written engineering design task, and group observations. Both systemic functional linguistics and mental models frameworks were utilized to interpret data and guide analysis. A series of regression analyses were conducted to determine if engineering language proficiency predicts group engineering term use, if conceptual understanding predicts group engineering term use, and if conceptual understanding predicts engineering language proficiency. Engineering academic language proficiency was found to be strongly linked to conceptual understanding in the context of introductory materials engineering courses. As the semester progressed, this relationship became even stronger. The more engineering concepts students are expected to learn, the more important it is that they are proficient in engineering language. However, exposure to engineering terms did not influence engineering language proficiency. These results stress the importance of engineering language proficiency for learning, but warn that simply exposing students to engineering terms does not promote engineering language proficiency.

Description
Although pragmatic analyses based on empirical data have been conducted throughout most of the Spanish-speaking world, Central America remains the most underrepresented region. This study examines the pragmatic strategies used by female Spanish speakers of Nicaragua and Panama in an advice-giving context. The data consists of eighteen role-plays recorded in Masaya, Nicaragua and Panama City, Panama in June and July of 2011. In the role-play situation, the interlocutor (fixed-role) requests advice from the participant, her best friend, regarding a serious issue in her marriage. The participant's advice-giving strategies are classified according to a categorization adapted from Blum-Kulka's request strategy taxonomy. This allows for a statistical analysis of how these strategies correspond to the three elements of Spencer Oatey's rapport management approach: behavioral expectations, face sensitivities and interactional wants. The results indicate strong similarities between participants from Nicaragua and Panama, both electing to respect all components of the association principle and to violate the equity principle, especially its autonomy control component. These results suggest that, at least in this advice-giving context between intimates, both Nicaraguan and Panamanian Spanish speakers prefer to impose their opinions and suggestions rather than respect the person's right to be treated fairly (i.e. equity principle) as well as to maintain a rapport-enhancing orientation rather than preserve their right to associate with others (i.e. association principle). The results of the pragmatic analysis show similarities with other research on directives in the Spanish-speaking world, including empirical studies in the Dominican Republic, Cuba, Venezuela and Spain. Specifically, these cultures are all associated with direct strategies and less mitigation, positive politeness, conventional indirectness and high involvement.

Description
This case study explores similarities and differences between the instructors' beliefs about oral corrective feedback and their actual practices in a summer Chinese program. This kind of feedback is beneficial for beginning college-level learners of Chinese to improve their speaking accuracy. The researcher conducted face-to-face interviews with two teachers of Chinese, focusing on their beliefs about oral corrective feedback in their language classrooms. In addition, the researcher recorded teacher-student interactions through class observation in order to analyze the teachers' actual practices of oral corrective feedback. The main findings show that the teachers hold similar beliefs on oral corrective feedback and its beneficial role in helping improve learners speaking accuracy. The fact is that they frequently provide oral corrective feedback in classroom, mostly using recasts. Implications are discussed in view of the necessity of using explicit feedback and recasts appropriately. In addition, this study demonstrates the need for specific professional development and teacher training about how to provide efficient corrective feedback.

Description
This investigation's goal was to add to the small body of research on pragmalinguistic acquisition of L2 Spanish. Specifically, it centered on the production of complaints in Spanish. Data was collected via a written Discourse Completion Task (DCT) of a complaint-provoking situation presented in a website voiceboard to two non-native speaker (NNS) students groups of different proficiency levels and to a native speaker (NS) control group. The lower proficiency group was comprised of 11 NNS enrolled in a 200 level beginning/intermediate Spanish grammar class and the advanced proficiency group of 11 NNS enrolled in a 400 level advanced Spanish conversation and composition class. Neither group contained any participants who had studied abroad or lived in a Spanish-speaking country for more than 3 months. The control group consisted of 10 NSs of Spanish who were all natives or current residents of Northern Mexico. Data from the DCT was categorized into strategies which were organized into Head Acts and Supporting Moves, Deference and Solidarity Politeness systems, according to the frameworks of Blum-Kulka, et al. (1989) and Scollon and Scollon (1983), respectively. The results of the analysis revealed that all three groups of participants have overarching similarities in the use of multiple Head Acts, some used several times throughout a response, to realize a complaint and used some Supporting Moves to mitigate these Head Acts. The lower proficiency group diverged from the advanced proficiency group and NS control group in that lower proficiency students not only used a fewer total strategies and strategy types, but also preferred Head Acts and Supporting Moves that expressed discomfort or dislike over strategies that expressed criticism, or requested a solution from the listener, these being the primary strategies preferred by the advanced proficiency and control group participants. It was also found that the percentage of Supporting Moves decreased with the raise in proficiency level, also. After a discussion of the results, pedagogical implications are given based on these results to help students notice and acquire pragmalinguistcally appropriate responses to complaint-provoking situations.
