Oxidation of silicon: further tests for the interfacial silicon emission model

The classical description of Si oxidation given by Deal and Grove has well-known limitations for thin oxides (below 200 Ã). Among the large number of alternative models published so far, the interfacial emission model has shown the greatest ability to fit the experimental oxidation curves. It relies on the assumption that during oxidation Si interstitials are emitted to the oxide to release strain and that the accumulation of these interstitials near the interface reduces the reaction rate there. The resulting set of differential equations makes it possible to model diverse oxidation experiments. In this paper, we have compared its predictions with two sets of experiments: (1) the pressure dependence for subatmospheric oxygen pressure and (2) the enhancement of the oxidation rate after annealing in inert atmosphere. The result is not satisfactory and raises serious doubts about the model’s correctness

Inter-comparisons of articulation tests on normal and hard-of-hearing listeners

This paper discusses a study undertaken to test various speech discrimination tests.

A comparison of the QuickSIN and TEN tests: two recent tests designed to predict patient benefit from high frequency amplification

This paper presents a comparison of two tests designed to predict which hearing impaired patients may benefit from high frequency amplification.

An analysis of the Woodcock Reading Mastery Tests and the Diagnostic Reading Scales for use with hearing-impaired children

This paper examines two individually administered diagnostic reading tests, the Woodcock Reading Mastery Tests and the Diagnostic Reading Scales, to determine their value for use with hearing-impaired children.

Comparison of video and toy reinforcers to motivate infants/toddlers for hearing tests

This paper is a study of the effectiveness between video and toy reinforcer types to motivate infants/toddlers for hearing tests. No significant differences were found between age groups or gender. Toy reinforcers were found to produce on average two more threshold estimates compared to video reinforcers. Variety, color and animation of animals may have contributed to this difference.

The Wechsler-Bellevue and the Wechsler Intelligence Scale for children as predictors of academic achievement for a severely hearing and speech impaired population

This paper reviews a study to determine the applicabilty of the Wechsler-Bellevue and the Wechsler Intelligence Scale for severely hearing impaired children.

A follow-up study of the academic achievement of hearing impaired children

This paper discusses a study to evaluate the academic progress of former students from CID including those who remained in special programs and those who were mainstreamed into regular public schools.

Comparing two receptive vocabulary tests: The receptive one word vocabulary test and the peabody picture vocabulary test

This paper discusses a study to determine whether the Receptive One Word Picture Vocabulary Test is more useful than the Peabody Picture Vocabulary Test in assessing the vocabularies of hearing imparied children.

Reading achievement of the deaf: another look

This paper discusses a study to examine the reading achievement of former CID students to determine the effectiveness of the CID reading program.

A literature review of three common balance tests: Electronystagmography, Rotary Chair Testing, and Computerized Dynamic Posturography

This paper discusses the rationale, clinical applications, advantages and disadvantages of three common balance function tests: Electronystagmography (ENG), Rotational Chair Testing (RCT), and Computerized Dynamic Posturography (CDP).

The effect of the handwriting without tears program on student cursive writing achievement at Central Institute for the Deaf (CID)

Handwriting Without Tears (HWT) is a multi-sensory program that provides a simpler approach to the instruction of cursive handwriting. It was administered to a sample of third graders to assess the effectiveness of the program and determine if it would be a viable option for handwriting instruction at CID.
