Description
Special education identification processes related to English language learners (ELs) in the United States have puzzled the field for decades. The phenomenon of referrals, the first step toward identification, is complex since it requires deciphering the root cause of students’ learning struggles—e.g., second language (L2) factors, the possibility of a learning disability (LD), or the combination of multiple other influences. To investigate the various influences contributing to learning difficulties, I centered this study on three potential sources, individual, institutional, and interpersonal. I aimed to answer, how did sociocultural influences mediate a teacher’s understanding of ELs’ competence? How did sociocultural influences mediate whether a teacher referred ELs to special education services? Using a cultural-historical theoretical approach, I sought deeper theoretical and empirical understandings into how institutional factors (e.g., tiered intervention contexts, policies), combined with other influences, mediated ELs’ referral decisions. I used a multiple parallel case study design following two fifth-grade ELs who faced the possibility of a referral. Interested in the interpersonal domain (e.g., interactions and communication among people), I zoomed in to a local process, student-teacher conferences to examine how classroom processes shaped teachers’ thoughts of students’ competence, and ultimately, referral decisions. I video-recorded teacher-student conference sessions over 14 weeks, and audio-recorded viewing sessions of the recorded conferences to understand teacher and student interpretations of learning competence. To understand how other dimensions (individual and institutional) contributed to teachers’ overall views about the student competence, I interviewed parents and school personnel, wrote observational field notes, and examined archival documents related to student learning over the entire fifth-grade year. I used inductive and iterative qualitative analytical approaches to craft the findings. My findings reaffirmed the complexity involved in finalizing ELs’ referral decisions. I found cultural factors intertwined with structural forces, driving students’ special education candidacies in divergent directions: one evaluated (LD); the other, retained. I also found the referral decisions were based on narrow understandings of learning and behaviors, lack of attention to students’ L2 needs, and faulty and overpowering structural forces which undermined teacher’s professional opinions about the referrals. These findings have implications for research, practice, and policy.

Description
Subject Pronoun Expression (SPE) has been extensively studied in monolingual and bilingual varieties of Spanish using the variationist framework. The goal of these studies has been to examine the linguistic and extra-linguistic factors that condition the expression and the omission of personal subject pronouns. Nonetheless, to date, there is no study of SPE in the Spanish of Equatorial Guinea, the only African country where it is an official language, and the single country where Spanish is exclusively a second language (L2). This dissertation fills this gap in the literature by accounting for SPE in Equatoguinean Spanish.
The research questions guiding this study concern the rates of Subject Pronoun Expression, its conditioning factors, and universal accounts of L2 acquisition, in particular, the Interface Hypothesis (IH). The study had 30 participants from Malabo, who took part in sociolinguistic interviews. These interviews were transcribed and analyzed using the mixed effects software Rbrul. Along the lines of the literature reviewed, the linguistic factor groups studied were grammatical person and number, reference, reflexivity, verb type, and ambiguity. By the same token, the extra linguistic factors analyzed were age, sex, education, native language (L1), and speaker as a random factor.
The results indicate that the Equatoguinean variety of Spanish has one of the lowest pronoun rates (19.1%), a finding that goes against the predictions of the IH. With regard to the linguistic factor groups that condition Subject Pronoun Expression, Equatoguinean Spanish shows an unorthodox ranking: grammatical person and number, ambiguity, verb class, and reference. Interestingly, the low ranking of reference gives support to the IH, which argues that L2 speakers have problems with constraints like the switch of the reference in subjects because it integrates discourse and pragmatic interfaces. The only significant extra-linguistic factor was education, whereas speakers’ L1 exerted no effect on SPE. Individual speaker was a significant random factor group, indicating that variation is great even in speakers with comparable education.
In sum, this study of a unique speech community provides new information on SPE of L2 Spanish. It also contributes to the fields of language contact, language variation, and second language acquisition.

Description
After continuous transnational migrations to Spain in the last few decades, a second generation of migrants has begun to experience an identity struggle as a result of the tensions between their culture of origin and the prevailing local customs and values. As such, this places them in what is called a third space. Considering the concept of imagined communities as advanced by Benedict Anderson, this dissertation contextualizes the testimonies of women from three migrant origin communities –Morocco, Equatorial Guinea, and China– to understand their way of inclusion and belonging.The study explores the works of Najat El Hachmi, Laila Karrouch, Miriam Hatibi, Lucia Mbomio, Carolina Nve Díaz San Francisco, Desiree Bela-Lobedde and Quan Zhou Wu. It includes fictional narrative, documentary, graphic novel and journalism. The discourse by Moroccan origin authors relates the discrimination that they experience to the tension between the dominant culture and the intersectional feminism with which they identify. Marianne Hirsch’s concept of postmemory enriches the understanding and helps to define the ongoing generational trauma, afropessimism, of women of Equatoguinean origin as a result of their experiences of colonialism and racism. Finally, Chinese-Spanish women write of discrimination in their close circles as a result of being heritage speakers, and also by being subjugated to their male counterparties in the family hierarchy.

Description
As any group-work member can attest, conveying information, and confirming understanding among group members can be a challenging first step in problem-solving. Despite being a ubiquitous strategy employed in many educational and organizational settings, there are collaborations that fall flat while others succeed. Recent strides have been made in the psycholinguistic approach to communication, evaluating the extent to which speakers align across lexical, syntactic, and semantic usages of language within various task environments, but gaps remain in understanding the role of language in open-ended, emergent problem-solving spaces. Study 1 examines the specific trends and functions of lexical, syntactic, and semantic alignment among speakers in a complex, creative problem-solving effort. As collaborators work through their tasks, lexical alignment decreases as semantic alignment increases and syntactic re-use decreases. These findings suggest alignment may be a sensitive mechanism that hinges on time spent in a collaborative environment and the influencing factor of goal type. More research is needed to understand the varying mechanisms across unique problem-solving spaces that vary in complexity, silence of referents, and cognitive load placed upon performers. Follow-up analyses explore how speakers use specific terms in their collaborative dialogues, assessing the roles of cognition- and action-related language. The use of thinking words (e.g. “think”, “wonder”) predicts when participants may hit an impasse in their collaborations. One interpretation suggests that cognition-related language tends to be involved when groups struggle to convey ideas. Findings from the current work have implications for interventions in organizational and educational domains, along with potential artificial intelligence applications.

Description
Drawing on previous empirical works in the field of Intercultural Competence (ICC) and telecollaboration (Chun, 2011; Elola & Oskoz, 2008; Furstenberg, 2004; Schulz, 2007), this study investigates how a completion of Cultura Project tasks in L1 and L2 helped to determine students' cultural values and behaviors, find out how their mental lexicons are structured, and assess a state of their critical cultural awareness. The theoretical framework for this study is based on Byram's (1997) work on ICC. As a part of their course work, Spanish language learners from a lower-division class participate in three Cultura Project tasks and provided their comments afterwards. The findings revealed cultural values and believes of the participants, as well as the organization of their mental lexicons. Moreover, the findings illustrated how the level of critical cultural awareness, as one of the components of ICC, could be assessed using the rubrics developed based on Byram's (1997) work on ICC and Bloom's (1990) revised taxonomy of learning skills. The results of the study contributed to the field of SLA on what is known about the roles of culturally-based questionnaires in critical cultural awareness assessment and the structure of mental lexicons of L2 learners.

Description
Diffusion Tensor Imaging may be used to understand brain differences within PD. Within the last couple of decades there has been an explosion of learning and development in neuroimaging techniques. Today, it is possible to monitor and track where a brain is needing blood during a specific task without much delay such as when using functional Magnetic Resonance Imaging (fMRI). It is also possible to track and visualize where and at which orientation water molecules in the brain are moving like in Diffusion Tensor Imaging (DTI). Data on certain diseases such as Parkinson’s Disease (PD) has grown considerably, and it is now known that people with PD can be assessed with cognitive tests in combination with neuroimaging to diagnose whether people with PD have cognitive decline in addition to any motor ability decline. The Montreal Cognitive Assessment (MoCA), Modified Semantic Fluency Test (MSF) and Mini-Mental State Exam (MMSE) are the primary tools and are often combined with fMRI or DTI for diagnosing if people with PD also have a mild cognitive impairment (MCI). The current thesis explored a group of cohort of PD patients and classified based on their MoCA, MSF, and Lexical Fluency (LF) scores. The results indicate specific brain differences in whether PD patients were low or high scorers on LF and MoCA scores. The current study’s findings adds to the existing literature that DTI may be more sensitive in detecting differences based on clinical scores.

Description
The goal of this study was to illuminate areas of strength within a sample of Hispanic, Spanish-speaking children (n = 446) from the early head start research and evaluation project, a multi method, multi reporter longitudinal study that involved children starting at 14-months through pre-kindergarten, with a 5th grade follow up assessment. A longitudinal path model examined relations between external factors (i.e., parent warmth and responsivity, home cognitive and language environment, child-directed speech), and internal factors (i.e., child self-regulation), and Spanish language before kindergarten, and English language at 5th grade. In addition to direct paths, indirect paths were included from external factors to language outcomes through self-regulation and Spanish language. After controlling for important demographic variables, analyses indicated that parents’ warmth and responsivity was directly related to children’s self-regulation and children’s English language proficiency in 5th grade. Home environment and self-regulation were directly related to children’s Spanish language proficiency. Children’s Spanish language proficiency was directly related to English language proficiency. Significant indirect effects emerged between parent warmth and responsivity to both Spanish and English language via children’s self-regulation. Results additionally evidenced significant indirect paths from home environment and self-regulation to English language through Spanish language. Direct paths between parent warmth/responsivity and Spanish language, home environment and English language, and child-directed speech and child regulation, Spanish language, and English language were not significant. Implications include current and future interventions targeted at bolstering parent-child interactions and regulation skills and to promote early educational programs supportive of both heritage and second languages.

Description
Words wield immense power. They help to shape realities, tell stories, and encompass deeper values and intentions on behalf of their users. Buzzwords are imprecise, trendy – and often-frustrating – words that are encountered in daily life. They frame problems, evoke emotional responses, and signal moral values. In this dissertation, I study buzzword use within the field of environmental conservation to better untangle the inherent tension they have long produced: do buzzwords help or hurt collective conservation efforts? Using a mixed methods approach, this dissertation provides descriptive and causal empirical evidence on many of the untested assumptions regarding the behavior, use, and impacts of buzzwords on conservation decision making. First, through a series of expert interviews with conservation professionals, I develop an empirically informed definition and understanding of buzzwords that builds upon the scholarly literature. It identifies eight defining characteristics, elaborates on the nuances of their use, life cycle, and context dependence, and sets forth a series of testable hypotheses on the relationship between buzzwords, trust, and perceptions. Second, I take this empirically informed understanding and employ a large-scale text analysis to interrogate the mainstream conservation discourse. I produce a list of buzzwords used across institutions (e.g., academia, NGOs) in the past five years and link them to predominant conservation frames, comparing the ways in which different institutions relate to and discuss conservation concepts. This analysis validates many long-held paradigms and ubiquitous buzzwords found in conservation such as sustainability and biodiversity, while identifying a more recently emerging framing of inclusive conservation. Third, I experimentally test a set of hypotheses on the effects that buzzwords have on decision making, as moderated through trust. This study finds evidence of a greenwashing effect, whereby buzzwords may produce marginal benefits to less trustworthy organizations through increases in credibility and group identity alignment, but do not outweigh the benefits of being trustworthy in the first place. In the face of many current global challenges requiring cooperation and collective action – such as climate change and environmental degradation – it is imperative to better understand the ways in which communication and framing (including buzzwords) influence decision making.

Description
This research consists of an eye-tracking study examining the efficacy of eye gaze indexing (EGIX) in manipulating viewer eye gaze and enhancing second language (L2) fingerspelling comprehension in American Sign Language (ASL) through a controlled laboratory experiment. The study consisted of two groups and two conditions, EGIX+/EGIX- to test the effect of EGIX on participant eye gaze (EG) behaviors and fingerspelling comprehension using eye-tracking software and a comprehension quiz. The results indicate that participant EG was the same regardless of whether the signer used EGIX.The results also indicated that participant comprehension scores were the same regardless of whether the model used EGIX. Several statistical analyses of comprehension and EG metrics found that as hand fixation duration, mouth fixation duration, number of hand fixations, and number of mouth revisits increased, comprehension performance decreased. On the other hand, the Area of Interest metrics did not affect performance or only revealed weak trends.
The decreases in comprehension may highlight that the students who struggled with comprehension looked more and longer at the mouth and hand as coping strategies to try to glean additional information from mouth grammar or that they were struggling to identify each letter handshape, rather than a causal relationship with EGIX.
Word length effect on comprehension was statistically significant, though varied by word length. Importantly, constraints from name origin may have played a role in the distribution of the comprehension decrease since words of Greek origins cause greater statistically significant reductions in performance.
The qualitative results show that students have a keen awareness of where they look while viewing signed videos. Noticing and perceived helpfulness did not show statistically significant impacts on performance universally. However, some students who reported noticing and reported the EGIX+ as helpful increased their score by 10% or higher on the mean comprehension of EGIX+ words.
The pedagogical takeaway is that the benefits of using EGIX to help novice to intermediate signers with fingerspelling comprehension are inconclusive. EGIX+ may provide substantial benefits for some individuals, but the effects are not generalizable.
