Effectiveness of impedance audiometry in diagnosing serous otitis media in children was examined in this study. The impedance test battery was performed on seventy-six ears of pre-myringotomy children (Mean age: 4.6 years). The status of the middle ear was assessed by the operating physician during surgery, and impedance results were correlated with the operative findings. Middle ear effusion was the variable that most influenced impedance results. Acoustic reflex threshold and tympanometry were the most sensitive tests in predicting effusion. Multiple correlations between these tests and the presence of significant effusion indicated that both measures together are diagnostically more sensitive than either test alone. Also, reflex measurement at one test frequency is as accurate a predictor of effusion as reflex measurement at all frequencies.

Research was conducted on twenty-seven preoperative myringotomy patients to clarify the correlation between tympanometry type and the presence of middle ear effusion. Test results indicate that the relationship between tympanometry and middle ear effusion is dependent on the amount of fluid present. In impacted ears primarily Type B tympanograms were obtained whereas for less than impacted ears all tympanogram types were seen. Also suggested was that a combination of height of the tympanogram and the amount of negative pressure may be diagnostically more important than negative pressure alone as an indicator of effusion. It was recommended that other measures in addition to tympanometry be employed in the diagnosis of middle ear effusion and that further research is needed to achieve optimal use of impedance audiometry.

This study is an examination of the theatre project at Tsa La Gi, a Cherokee cultural center in Tahlequah, Oklahoma. The thesis is organized into three areas: the drama, the theatre design, and the production techniques. Chapter I reports the process of the formulation of Trail of Tears and analyzes its success. Chapter II describes and interprets the process of the design of the physical theatre. Chapter III reports the techniques used in play production at Tsa La Gi and interprets their effects. Chapter IV presents conclusions about the success of the theatre project. This report accepts evidence that the theatre project at Tsa La Gi is a highly successful one, both economically and artistically.

This paper reports on the comparison of the performance of fourteen normal hearing listeners and fourteen individuals with sensorineural hearing loss on the Synthetic Sentence Identification (SSI) and the Northwestern Auditory Test No. 6 (NU 6) in order to determine whether there are differences in performance of the two groups of listeners on the SSI and NU 6 and whether either test better reflects aided improvement and residual deficit. Both measures demonstrated significant aided improvement. The results of this study do not suggest a single best discrimination test which can reflect a real-life listening situation. The primary consideration in the hearing aid evaluation is flexibility in determining the appropriate level for the primary signal and the listening conditions.

Time-compressed speech discrimination of children grouped as high and low risk on a reading-readiness test was examined. Children were grouped according to performance on a measure of reading-readiness skills. All passed a hearing screening at fifteen decibels for octave frequencies 250-4000 Hz. The Word Intelligibility by Picture Identification (WIPI) comprised the time-compressed speech task, in a sound field at seventy decibels Sound Pressure Level and zero degrees azimuth. The protocol for administration of the time-compressed speech task was sixty per cent time compression, then zero per cent time compression. Significant effects appeared for time compression ratio and test group. Average difference was twelve per cent and approximately eight per cent at zero.

The SRA-10 is a tactile instrument which provides hearing impaired subjects with acoustic transforms that can be easily discriminated on the skin. Whether or not the SRA-10 is an effective means of training speech-language skills in profoundly hearing impaired subjects was the focus of this investigation. Two profoundly hearing impaired subjects were trained on phonetic reception/production tasks and on discrimination of multisyllabic words. Each subject served as his own control, wearing the SRA-10 for 14, 30 minute sessions, and a Bioacoustics 70-B auditory training unit for the same period of time. Results indicated a greater correct performance gain function with the SRA-10 than with the 70-B, suggesting that speech perception/production training using the SRA-10 or similar device would be superior to training using acoustic amplification.

This thesis is designed to determine the impact of the archetype of the Great Mother on the plot, characterizations, and interpersonal relationships in three contemporary films. Chapter I describes the elements and applications of the archetype and the Jungian analysis employed in the study. Chapter II details the phases of the Great Mother archetype and discusses Jung's process of individuation and how the Great Mother controls this quest. Chapters III, IV, and V focus on The Heretic, Network, and Looking for Mr. Goodbar respectively. Chapter VI summarizes the existence and power of the archetype in the films and postulates that the image of women in film may be stereotyped due to the Great Mother archetype.

The purpose of the study was to compile a catalog of two sections: (1) a comprehensive, alphabetic, annotated list of North Texas State University (NTSU) Library films (the general catalog); and (2) a classified and cross-referenced film and broadcasting filmography of NTSU Library films. The catalog represents all films available for distribution from the NTSU Library as of July, 1976. The cataloging and compilation process is described. An analysis is made of the NTSU Library film collection. The titles of 13 films are recommended for addition to the collection.
