Description
The speech of non-native (L2) speakers of a language contains phonological rules that differentiate them from native speakers. These phonological rules characterize or distinguish accents in an L2. The Shibboleth program creates combinatorial rule-sets to describe the phonological pattern of these accents and classifies L2 speakers into their native language. The training and classification is done in Shibboleth by support vector machines using a Gaussian radial basis kernel. In one experiment run using Shibboleth, the program correctly identified the native language (L1) of a speaker of unknown origin 42% of the time when there were six possible L1s in which to classify the speaker. This rate is significantly better than the 17% chance classification rate. Chi-squared test (1, N=24) =10.800, p=.0010 In a second experiment, Shibboleth was not able to determine the native language family of a speaker of unknown origin at a rate better than chance (33-44%) when the L1 was not in the transcripts used for training the language family rule-set. Chi-squared test (1, N=18) =1.000, p=.3173 The 318 participants for both experiments were from the Speech Accent Archive (Weinberger, 2013), and ranged in age from 17 to 80 years old. Forty percent of the speakers were female and 60% were male. The factor that most influenced correct classification was higher age of onset for the L2. A higher number of years spent living in an English-speaking country did not have the expected positive effect on classification.

Description
Research regarding social competence is growing rapidly, but there remain a few aspects of social development that merit more attention. The presented pair of studies were planned to address two such areas in the social development literature, specifically the longitudinal trajectories of social competence and the role of social competence in second language development in language minority (LM) students. The goal of the first investigation was to examine the developmental trends of interpersonal skills (IS) across the early childhood and elementary school years in a nationally representative, U.S. sample. The goal of the second study was to examine whether differing trajectories of IS development in language minority children in the U.S. were related to their language and literacy (LL) skills at grade 5. Both studies utilized data from the Early Childhood Longitudinal Study - Kindergarten Class of 1998-1999 and modeled ratings of children's IS at five time points between fall of kindergarten and spring of fifth grade using latent class growth analyses in Mplus. In study 1, the best model was a quadratic two-class latent class growth analysis. Trajectory class 1 was a higher-level path with a marginally significant non-linear shape and class 2 was a primarily stable, moderate level path with a slight, non-significant increase over time. The same pattern of results emerged for both boys and girls separately as with the combined-sex model, and in all three final models the proportion of the sample in the higher-level class was greater than the moderate-level class. In study 2 a sample of U.S. children whose primary language at home was something other than English was utilized. LL at the start of kindergarten and sex were included as covariates and LL in fifth grade as a distal outcome. The best model for the data was a cubic two-class latent class growth analysis. Class 1 followed a higher-level path with small, incremental change over time and class 2 was a moderate-level path with greater undulation. Both covariates significantly predicted latent class and language and literacy scores at grade 5 differed significantly across classes.

ABSTRACT
The absence of the consonant sound /p/ in Libyan Arabic leads Libyan speakers of English to pronounce /p/ as /b/. This study examines how Libyan Arabic speakers distinguish the English /p/ and /b/ in their production of L2 English. The study also examines the effect of the production contexts and the learning environment on two groups of Libyan Arabic speakers' attainment of the English /p/ in the USA and Libya. The study collected voice recordings of word-initial /p/ and /b/ in isolated-words, minimal pairs, and sentences in English from both Libyan Arabic speakers and American English speakers. The study also collected Libyan Arabic stop consonants /b/, /t/, /d/, /k/, and /g/ from the Libyan participants. The voice recording data were collected using the WhatsApp mobile application from all participants and the Libyan Arabic participants were also asked to fill an online survey. Using voice onset time (VOT) as a measurement tool, this study measured the English and Libyan Arabic data through Praat software. The findings show that most Libyan Arabic participants distinguish between /p/ and /b/, but they did not have as high VOT averages as the American participants' /p/. It also reveals that the production context, especially in minimal pairs and sentence contexts, has an effect on their participants' production. However, the learning environment does not have an effect on the Libyan participants' pronunciation of /p/ in this study.

Description
Using Spencer-Oatey's rapport management approach, the present study evaluates the interlanguage pragmatic development of 17 native English-speaking American learners over the course of a semester in Spain, specifically in terms of the strategies they used in their second language (L2) to manage rapport in an advice-giving, oral role-play situation at semester start and semester end. To allow for a more in-depth analysis of the effect that a semester abroad has on Spanish L2 advice-giving behaviors, the learners were grouped into two distinct proficiency levels. Group 1 (n=9) represents learners who entered the semester abroad with a beginning to intermediate-low proficiency level and group 2 (n=8) represents learners who entered the semester abroad with an intermediate-high proficiency level. The results indicate that both learner groups had similar overarching behavioral expectations in this context. Specifically, both sets of learners expressed empathy, involvement, and respect for the interlocutor, while at the same time they used advice-giving strategies of varied illocutionary force to claim authority in addressing the interlocutor's dilemma. Both groups also balanced face sensitivities through strategies that both enhanced and challenged the interlocutor's identity face. However, it is argued that in this context claiming authority and challenging the interlocutor's identity face were permitted behaviors that emphasized the relational goals of the participants. Additionally, when developmental differences between the two proficiency levels were analyzed, the results showed that learner proficiency had an impact on specific strategy choices.

Description
This semester-long study examined the functions for which English (L1) and Spanish (L2) were used in two intact hybrid Spanish as a foreign language (FL) university classes at the 202 (fourth semester) level. Five 75-minutes classes of two instructors were observed by the researcher, video- and audio-recorded, and transcribed. A survey was also used to determine the functions for which the instructors and students believed that Spanish and English were used in the classroom, and the functions for which both believed that the two languages should be used. Talking about a test and teaching grammar were the functions for which both instructors used the most English and the most Spanish. The questionnaire results indicated that the students who heard more Spanish in the classroom would have preferred that their instructor had used less Spanish for the functions of checking how well students understand a reading in class as well as when giving instructions or explaining how to do group activities. The Minnesota Language Proficiency Assessment for listening at the Intermediate-High level was administered to the students of both instructors at the beginning and at the end of the semester. The classroom observations indicated that although both instructors used more than 50% words in English during their classes, one instructor used twice as many words in Spanish as did the other. However, the results of the study revealed no significant relationship between the amount of Spanish used by the instructors in the classroom and the students' progress on listening proficiency from the beginning to the end of the semester.

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.

Description
Differentiating bilingual children with primary language impairment (PLI) from those with typical development in the process of learning a second language has been a challenge. Studies have focused on improving the diagnostic accuracy of language measures for bilinguals. However, researchers are faced with two main challenges when estimating the diagnostic accuracy of new measures: (a) using an a priori diagnosis of children (children with and without PLI), as a reference may introduce error given there is no gold standard for the a priori classification; and (b) classifying children into only two groups may be another source of error given evidence that there may be more than two language ability groups with different strengths and weaknesses or, alternatively, a single group characterized by a continuum of language performance. The current study tested for the number of distinct language ability groups and their characteristics in predominately Spanish-speaking children in the U.S. without using an a priori classification as a reference. In addition, the study examined to what extent the latent groups differed on each measure, and the stability of language ability groups across three assessment methods in Spanish (standardized tests, language sample analyses, and comprehensive assessment), taking in to account English and non-verbal cognitive skills. The study included 431 bilingual children attending English-only education. Three latent profile analyses were conducted, one for each method of assessment. Results suggested more than two distinct language ability groups in the population with the method of assessment influencing the number and characteristics of the groups. Specifically, four groups were estimated based on the comprehensive assessment, and three based on standardized assessment or language sample analysis in Spanish. The stability of the groups was high on average, particularly between the comprehensive assessment and the standardized measures. Results indicate that an a priori classification of children into two groups, those with and without PLI, could lead to misclassification, depending on the measures used.

Description
Identification of primary language impairment (PLI) in sequential bilingual children is challenging because of the interaction between PLI and second language (L2) proficiency. An important step in improving the accurate diagnosis of PLI in bilingual children is to investigate how differences in L2 performance are affected by a length of L2 exposure and how L2 assessment contributes to differentiation between children with and without PLI at different L2 proficiency levels. Sixty one children with typical language development (TD) ages 5;3-8 years and 12 children with PLI ages 5;5-7;8 years participated. Results revealed that bilingual children with and without PLI, who had between 1 and 3 years of L2 exposure, did not differ in mean length of utterance (MLU), number of different words, percent of maze words, and performance on expressive and receptive grammatical tasks in L2. Performance on a grammaticality judgment task by children with and without PLI demonstrated the largest effect size, indicating that it may potentially contribute to identification of PLI in bilingual populations. In addition, children with PLI did not demonstrate any association between the length of exposure and L2 proficiency, suggesting that they do not develop their L2 proficiency in relation to length of exposure in the same manner as children with TD. Results also indicated that comprehension of grammatical structures and expressive grammatical task in L2 may contribute to differentiation between the language ability groups at the low and intermediate-high proficiency levels. The discriminant analysis with the entire sample of bilingual children with and without PLI revealed that among L2 measures, only MLU contributed to the discrimination between the language ability groups. However, poor classification accuracy suggested that MLU alone is not a sufficient predictor of PLI. There were significant differences among L2 proficiency levels in children with TD in MLU, number of different words, and performance on the expressive and receptive grammatical tasks in L2, indicating that L2 proficiency level may potentially impact the differentiation between language difficulties due to typical L2 acquisition processes and PLI.

Description
ABSTRACT This study focuses on second language acquisition process amongst East Asian adult learners at an English and Culture Acquisition Program (ECAP) classroom. To understand their English learning experience, this study employs classroom observation, participant interview and document collection as research methods. The findings of this work suggest that ECAP does intend to help learners acquire English language proficiency in ways that were responsive to both the sociocultural backgrounds and individual needs of participants. ECAP also respects and promotes the learners' autonomy in the learning process. However, the program administrators and teachers still need to deepen their understanding of East Asian learners' sociocultural heritage and individual needs and improve facilitation accordingly.
