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
For this project the main goal was to create a curriculum aimed at fourth grade students. This curriculum was intended to introduce them to different forms of communication, and teach them the skills, attitudes, behavior, and knowledge that would enable them to be able to communicate and interact better with a wide range of people with different types of communication styles. American Sign Language was used for this curriculum as an example of an alternative communication method. The project included developing teaching materials and lessons which made up the curriculum, after that this curriculum was implemented with 11 fourth grade students.

Description
The manner in which plants are able to acquire plant nitrate (NO3-) varies depending on a combination of distinct processes between "root high-and low-affinity NO-3 transporters and the proton gradient that is generated by the plasma membrane H+-ATPase" (Paez-Valencia et al, 2013). In this study we analyzed the response to limiting nitrate (0.5 mM) of seventy-four breeding lettuce (Lactuca sativa) lines derived from the cross Parade vs. Pavane. Parade had an enhanced root acidification capacity when grown under Nitrate limitation in comparison to Pavane, which had a poor root acidification capacity. Two successive experiments were conducted under distinct environmental conditions to evaluate the performance of the different breeding lines based on their ability to grow under nitrogen limitation as an indirect measurement of their ability to take up nitrate. Specific parameters were established in order to properly classify strong and weak breading lines based on the following characterizations: 1) Average fresh shoots and roots weights; 2) Color of leaves (green vs. yellow); and 3) Root acidification capacity. In essence, the measurement of these parameters is would allow for the identification of breeding lines that demonstrated enhanced performance under Nitrate limitation in order to observe if their performance correlated with root acidification capacity. The breeding line's biomass, indicated by the average fresh shoots and roots weights, determined the plant's ability to uptake Nitrogen; whereas, large biomass values indicated Nitrogen uptake, low values indicated a low Nitrogen uptake (Javadiyan, 2008). To determine Nitrogen nutrition, the colors of the plants' leaves were observed throughout the duration of the study; a green color demonstrated appropriate Nitrogen nutrition, whereas as a yellow color identified Nitrogen deficiency (Yang, 2003). In addition to the nutrients that composed the media in the agar plates, a pH indicator (Bromocresol Purple Dye) was utilized to monitor root acidification; the purple indicator transformed into a yellow color upon the occurrence of acidification. In both experiments, a direct correlation between the root acidification capacity and the biomass of each breeding line could not be determined. Strong breeding lines were identified when they demonstrated large biomass measurements, which were obtained from the average fresh shoots and roots, and also a proper nitrogen nutrition status, which was shown through their green leaf phenotypic characteristics. These two characterizations were significantly prevalent in four breeding lines (B9, B17, C1, and C21), which on average outperformed the parental lines (Controls: P12 and P13).

Description
Despite the vast research and attention given to education, little is known about teacher preparation to raise the quality of education for the honors students. There is an apparent disconnect from the honors students at Arizona State University and the education major. This study uncovers the perspective of the honors students who are majoring in education. Qualitative data was collected using one-on-one interviews. Results showed that all seven interviewed subjects were not satisfied with the education they were receiving as an honors education major.

Description
This thesis compared two measures of phonological assessment of children, Shriberg and Kwiatkowski's 1980 Percentage of Correct Consonants (PCC) and Ingram's 2002 Proportion of Whole Word Proximity (PWP). Two typically developing two-year-old children were initially studied, and then nine children with speech sound disorders. The children's words were divided into four categories ranging from least complex to most complex. It was hypothesized that the measures would correlate with word simplicity. The hypothesis was supported for the two typically developing children, and for five of the children with speech sound disorders. The other four children with speech disorders, however, did not show the correlation. It was concluded that PCC and PWP did not measure the same thing, that PCC alone was sufficient to assess the typically developing children, and that the two measures together better captured the ability of the children with speech sound disorders than either singularly. Further, the differences between the two groups of children with speech sound disorders were interpreted as showing a difference between phonological delay and phonological disorder.

Description
This thesis investigated the impact of word complexity as measured through the Proportion of Whole Word Proximity (PWP; Ingram 2002) on consonant correctness as measured by the Percentage of Correct Consonants (PCC; Shriberg & Kwiatkowski 1980) on the spoken words of monolingual Spanish-speaking children. The effect of word complexity on consonant correctness has previously been studied on English-speaking children (Knodel 2012); the present study extends this line of research to determine if it can be appropriately applied to Spanish. Language samples from a previous study were used (Hase, 2010) in which Spanish-speaking children were given two articulation assessments: Evaluación fonológica del habla infantil (FON; Bosch Galceran, 2004), and the Spanish Test of Articulation for Children Under Three Years of Age (STAR; Bunta, 2002). It was hypothesized that word complexity would affect a Spanish-speaking child’s productions of correct consonants as was seen for the English- speaking children studied. This hypothesis was supported for 10 out of the 14 children. The pattern of word complexity found for Spanish was as follows: CVCV > CVCVC, Tri-syllables no clusters > Disyllable words with clusters.

Description
In this study, the Bark transform and Lobanov method were used to normalize vowel formants in speech produced by persons with dysarthria. The computer classification accuracy of these normalized data were then compared to the results of human perceptual classification accuracy of the actual vowels. These results were then analyzed to determine if these techniques correlated with the human data.

Description
Pitch and timbre perception are two important dimensions of auditory perception. These aspects of sound aid the understanding of our environment, and contribute to normal everyday functioning. It is therefore important to determine the nature of perceptual interaction between these two dimensions of sound. This study tested the interactions between pitch perception associated with the fundamental frequency (F0) and sharpness perception associated with the spectral slope of harmonic complex tones in normal hearing (NH) listeners and cochlear implant (CI) users. Pitch and sharpness ranking was measured without changes in the non-target dimension (Experiment 1), with different amounts of unrelated changes in the non-target dimension (Experiment 2), and with congruent/incongruent changes of similar perceptual salience in the non-target dimension (Experiment 3). The results showed that CI users had significantly worse pitch and sharpness ranking thresholds than NH listeners. Pitch and sharpness perception had symmetric interactions in NH listeners. However, for CI users, spectral slope changes significantly affected pitch ranking, while F0 changes had no significant effect on sharpness ranking. CI users' pitch ranking sensitivity was significantly better with congruent than with incongruent spectral slope changes. These results have important implications for CI processing strategies to better transmit pitch and timbre cues to CI users.

Description
Research on /r/ production previously used formant analysis as the primary acoustic analysis, with particular focus on the low third formant in the speech signal. Prior imaging of speech used X-Ray, MRI, and electromagnetic midsagittal articulometer systems. More recently, the signal processing technique of Mel-log spectral plots has been used to study /r/ production in children and female adults. Ultrasound imaging of the tongue also has been used to image the tongue during speech production in both clinical and research settings. The current study attempts to describe /r/ production in three different allophonic contexts; vocalic, prevocalic, and postvocalic positions. Ultrasound analysis, formant analysis, Mel-log spectral plots, and /r/ duration were measured for /r/ production in 29 adult speakers (10 male, 19 female). A possible relationship between these variables was also explored. Results showed that the amount of superior constriction in the postvocalic /r/ allophone was significantly lower than the other /r/ allophones. Formant two was significantly lower and the distance between formant two and three was significantly higher for the prevocalic /r/ allophone. Vocalic /r/ had the longest average duration, while prevocalic /r/ had the shortest duration. Signal processing results revealed candidate Mel-bin values for accurate /r/ production for each allophone of /r/. The results indicate that allophones of /r/ can be distinguished based the different analyses. However, relationships between these analyses are still unclear. Future research is needed in order to gather more data on /r/ acoustics and articulation in order to find possible relationships between the analyses for /r/ production.
