Description
The purpose of the present study was to determine if vocabulary knowledge is related to degree of hearing loss. A 50-question multiple-choice vocabulary test comprised of old and new words was administered to 43 adults with hearing loss (19 to 92 years old) and 51 adults with normal hearing (20 to 40 years old). Degree of hearing loss ranged from mild to moderately-severe as determined by bilateral pure-tone thresholds. Education levels ranged from some high school to graduate degrees. It was predicted that knowledge of new words would decrease with increasing hearing loss, whereas knowledge of old words would be unaffected. The Test of Contemporary Vocabulary (TCV) was developed for this study and contained words with old and new definitions. The vocabulary scores were subjected to repeated-measures ANOVA with definition type (old and new) as the within-subjects factor. Hearing level and education were between-subjects factors, while age was entered as a covariate. The results revealed no main effect of age or education level, while a significant main effect of hearing level was observed. Specifically, performance for new words decreased significantly as degree of hearing loss increased. A similar effect was not observed for old words. These results indicate that knowledge of new definitions is inversely related to degree of hearing loss.

The neurobiology of sentence comprehension: an fMRI study of late American Sign Language acquisition
Description
Language acquisition is a phenomenon we all experience, and though it is well studied many questions remain regarding the neural bases of language. Whether a hearing speaker or Deaf signer, spoken and signed language acquisition (with eventual proficiency) develop similarly and share common neural networks. While signed language and spoken language engage completely different sensory modalities (visual-manual versus the more common auditory-oromotor) both languages share grammatical structures and contain syntactic intricacies innate to all languages. Thus, studies of multi-modal bilingualism (e.g. a native English speaker learning American Sign Language) can lead to a better understanding of the neurobiology of second language acquisition, and of language more broadly. For example, can the well-developed visual-spatial processing networks in English speakers support grammatical processing in sign language, as it relies heavily on location and movement? The present study furthers the understanding of the neural correlates of second language acquisition by studying late L2 normal hearing learners of American Sign Language (ASL). Twenty English speaking ASU students enrolled in advanced American Sign Language coursework participated in our functional Magnetic Resonance Imaging (fMRI) study. The aim was to identify the brain networks engaged in syntactic processing of ASL sentences in late L2 ASL learners. While many studies have addressed the neurobiology of acquiring a second spoken language, no previous study to our knowledge has examined the brain networks supporting syntactic processing in bimodal bilinguals. We examined the brain networks engaged while perceiving ASL sentences compared to ASL word lists, as well as written English sentences and word lists. We hypothesized that our findings in late bimodal bilinguals would largely coincide with the unimodal bilingual literature, but with a few notable differences including additional attention networks being engaged by ASL processing. Our results suggest that there is a high degree of overlap in sentence processing networks for ASL and English. There also are important differences in regards to the recruitment of speech comprehension, visual-spatial and domain-general brain networks. Our findings suggest that well-known sentence comprehension and syntactic processing regions for spoken languages are flexible and modality-independent.

Description
Language, as an abstract, is one of the most sophisticated inventions even devised by human beings. Reading alone is a multi-faceted problem, and understanding how the brain solves it can offer enormous benefits for scientists and language-enthusiasts alike. In order to gain a more complete picture of how language and the brain relate, Chinese, an East Asian logographic language, and English, an alphabetic language, were compared and contrasted using all available scientific literature in both psychology and neuroimaging. Taken together, these findings are used to generalize the processing of written language. It was found that the hypothesis of a neuroplastically adaptable network that recruits brain areas based on the demands of a specific language has stronger support in current research than does the model of a fixed language network that is merely tuned for different languages. These findings reiterate the need for meticulous control of variables in order to reasonably compare language tasks and also demands more precise localization and labeling of brain regions for the purpose of determining function of individual areas.

Description
The increase of Traumatic Brain Injury (TBI) cases in recent war history has increased the urgency of research regarding how veterans are affected by TBIs. The purpose of this study was to evaluate the effects of TBI on speech recognition in noise. The AzBio Sentence Test was completed for signal-to-noise ratios (S/N) from -10 dB to +15 dB for a control group of ten participants and one US military veteran with history of service-connected TBI. All participants had normal hearing sensitivity defined as thresholds of 20 dB or better at frequencies from 250-8000 Hz in addition to having tympanograms within normal limits. Comparison of the data collected on the control group versus the veteran suggested that the veteran performed worse than the majority of the control group on the AzBio Sentence Test. Further research with more participants would be beneficial to our understanding of how veterans with TBI perform on speech recognition tests in the presence of background noise.

Description
The goal of this thesis project is to provide insight into the lives of Syrian refugees, asylum seekers, and migrants who have left Syria for the United States within the last 6 years, after the start of the conflict there. I have interviewed individuals who come from different regions of Syria, are members of different religious groups, and who have different opinions in regard to the conflict in Syria. One of the questions that I was most curious to ask and have answered was why America was selected as the final destination for their immigration. Along with their backstories from their time in Syria up until their arrival in the United States, I did research into the immigrants' acclimation process, and whether they feel that private organizations or that our government have helped them in that regard. I also collected data to see what the average amount of time to find a job and become self-sufficient in the United States is for these persons and their families. Although most educated Syrians know French, English, and Arabic, I was proven right in my hypothesis that many refugees have come to the United States knowing little, if any, English. Research was done into the programs that are offered to these people and their personal efforts to learn English were also documented. The primary purpose of this thesis was to find the economic and social effects of Syrian immigrants in the state of Arizona, and hopefully, on a larger scale. It was very challenging to get exact numbers on the amount of refugees and impossible to get specific details in regard to their economic impact on the economy. In order to get an approximation, I read David Card's research into the Mariel Boatlift, which documented the economic effects of Cuban immigrants on the Miami labor market, and Semih Tumen's work, titled, "The Economic Impact of Syrian Refugees on Host Countries: Quasi-Experimental Evidence from Turkey" which provides research-based analysis of the specific effects of Syrian refugees on the economy of Turkey. Conclusions for both the economic and social impact of Syrian refugees in the state of Arizona were made. Due to the current low numbers of Syrian refugees living in Arizona and the mentality that many of them possess, there is a net neutral economic impact. In regard to social impact, I was surprised to learn that the acclimation process for Syrian immigrants is relatively rapid, particularly when compared to other immigrant and refugee populations.

Description
Working memory and cognitive functions contribute to speech recognition in normal hearing and hearing impaired listeners. In this study, auditory and cognitive functions are measured in young adult normal hearing, elderly normal hearing, and elderly cochlear implant subjects. The effects of age and hearing on the different measures are investigated. The correlations between auditory/cognitive functions and speech/music recognition are examined. The results may demonstrate which factors can better explain the variable performance across elderly cochlear implant users.

Description
The purpose of this paper is to evaluate the effectiveness of a craft book used for stimulation therapy on the phonetic sounds /ŋ/, /r/, /s/, /ʃ/, /tʃ/, and /θ/. The book is specifically geared toward children who do not qualify for speech remediation services but who may be at risk of a speech sound disorder. Four children participated in the study with ages ranging from 4;3-7;6. The study lasted for four weeks in which data was collected on a weekly basis via Likert Scale surveys in accordance with two conversational speech samples. The speech samples were phonetically transcribed with minimal differences pre and post use of the craft book. Data from the surveys give insight to the children’s favorite crafts, the level of difficulty of each craft, and the likelihood of the craft book to be used as part of a remediation program. The study had limitations in sample size, duration, and number of craft activities. Future revisions should include increasing the number of crafts available per chapter and incorporating into the introduction an educational component for parents.

Description
This paper analyzes modern day Cuba and draws conclusions about the most likely future political and economic events that will take place. Because of Cuba's troubled economy, leadership change and the world's continued shift towards democratization, Cuba is in a position where drastic changes in its government and economic structure may occur. This paper investigates Cuba's history, politics, economy, and the general quality of life of its citizens, which are used to help predict what may happen to the Cuban government in the near future. The paper also analyzes options for foreign nations' policy towards Cuba and summarizes what actions they may take to increase the likelihood of an economic and political transition. Cuba's economic structure needs drastic reform, the reluctant privatization only increases wealth disparity, trust in the government continues to get weaker as more information and its human rights violations are causes of huge concern. There are four possible outcomes for Cuba's future: stagnation, adopting the mixed economic model, a peaceful transition to a democratic model, and rebellion. There is evidence that Cuba will not make drastic policy changes in favor of liberalization in the immediate future, however, if the economic conditions are not improved and an economic crisis ensues, this paper asserts that another revolution or coup will likely occur. The resulting government may be a new autocratic leader that fills the vacuum of leadership, or a democratic regime depending on the nature of the rebellion. The exact future of Cuba is uncertain, but one thing is clear, change is on the horizon.

Description
Being Sparky will be a sports documentary about the life of Walker McCrae as Arizona State University’s mascot, Sparky. The idea behind this documentary is to outline all that encompasses being Sparky from events themselves to student life, as well as the time commitment needed for such a role. The purpose is to show the impact Sparky has not only on the university but on the people who are Sparky. While it can just be wearing a costume and getting really sweaty, the work one puts in to it will always reap rewards. To most people, Sparky life seems simple and straightforward but the reality is that it is much more complex and that is what we want to demonstrate in this documentary.

Description
My thesis offers original research is in its direct analysis of the IRS conflict of interest regulations and their applicability to STOs, its discussion of my experience setting up an STO, and my interviews of State Legislators as a primary source. The primary goals of my investigation are to 1. Determine the regulations and standards that exist to prevent conflicts of interest in the operation of Arizona STOs. 2. Examine instances of alleged conflicts of interest encountered by STO operators. 3. Discuss the ethical implications of STO operator actions in situations of conflicts of interest. And 4. Propose legislative solutions to remove any and all conflicts of interest. From my examination of financial records and from my interviews with other state legislators, I have concluded that Arizona Christina School Tuition Organization is violating IRS regulations by operating with an objective of conferring on its director a private benefit. The STO I helped form, ------------- STO will need to carefully document its expenses and contracts to justify its overhead margin or else risk running afoul of the same IRS regulations. Even if an STO like ------------- STO, is allowed by Arizona law to have an overhead margin of 10%, those expenses must be justified, particularly if they confer a private benefit to restricted persons. Ultimately, even if an STO deliberately flouts IRS regulations regarding private benefits realized by "disqualified" persons, it is highly unlikely that the STO will face IRS scrutiny. Therefore, there exist sufficient federal regulatory safeguards to prevent financial conflicts of interest among Arizona STO board members, but such regulations are not sufficiently enforced to prevent those conflicts of interest.
