Purpose: To examine differences in vocal fold vibratory phase asymmetry judged from stroboscopy, high-speed videoendoscopy (HSV), and the HSV-derived playbacks of mucosal wave kymography, digital kymography, and a static medial digital kymography image of persons with hypofunctional and hyperfunctional voice disorders. Differences between the…

We present results obtained with new instrumental methods for the acoustic analysis of prosody to evaluate prosody production by children with Autism Spectrum Disorder (ASD) and Typical Development (TD). Two tasks elicit focal stress--one in a vocal imitation paradigm, the other in a picture-description paradigm; a third task also uses a vocal…

This dissertation studies clouds over the polar regions using the Multi-angle Imaging SpectroRadiometer (MISR) on-board EOS-Terra. Historically, low thin clouds have been problematic for satellite detection, because these clouds have similar brightness and temperature properties to the surface they overlay. However, the oblique angles of MISR…

Early math skills are the strongest predictors of later math achievement in school. This two-wave study addressed three research questions about the role of families in fostering these skills in preschool-aged children. First, how do families talk about math at home? Second, how do these conversations vary across families with different…

The plumbing products most appropriate for a high-end hotel or executive restroom will differ from those most suited for school and university restrooms, where large numbers of boisterous students may charge through the doors all day long. However, installing plumbing that can stand up to rough-and-tough student use does not have to compromise…

Two studies were completed that focused on instrumentation and procedural issues associated with measurement of lingua-palatal contact pressure (LPCP) during speech. In the first experiment, physical features and response characteristics of 2 miniature pressure transducers (Entran EPI-BO and Precision Measurement 60S) were evaluated to identify a…

The role analytical instrumentation performs in the surveillance and control of the quality of water resources is reviewed. Commonly performed analyses may range from simple tests for physical parameters to more highly sophisticated radiological or spectrophotometric methods. This publication explores many of these types of water quality analyses…

The assistive technology (AT) field acknowledges that different stakeholders vary in their perspectives of service delivery outcomes. While the literature delineates consumers, caregivers and providers as stakeholders with distinct views, very little research documents these unique perspectives. This study reports on the perspectives of (a)…

This appendix contains materials on the development and validation of instruments and scales used to assess the nursing program of Ryerson Polytechnical Institute in Toronto, Canada. Some of the instruments included the following: (1) Introductory Information Questionnaire, which investigates students' socioeconomic and ethnic backgrounds,…

SCORIT, a computer program which processes student responses to test items, is described and explained. The method of scoring responses according to an original test design and possible alternate test designs is detailed. The printing and punching of reports in a form suitable for correlational analysis are covered. A program description is…

Many behavior patterns that impact on physical activity experiences are established in early childhood, therefore it is important that valid, reliable, and feasible measures are constructed to identify children who are not developing appropriate and healthy activity habits. In this study, measures of physical activity derived by accelerometry and…

We focus on the music students at a conservatoire (A) that only trains performers and composers (performers/composers); a conservatoire (B) that also trains classroom teachers (education students); and a university (C) with only education students. We used a questionnaire to compare the experience and beliefs as instrumental teachers of the…

Available methods for collecting human factors data rely heavily on observations, interviews, and questionnaires. A need exists for other methods. The feasibility of using two-way voice-radio for this purpose was studied. The data collection methodology consisted of a human factors analyst talking from a radio base station with technicians wearing…

Profiles a class exercise that teaches the importance of developing an accurate definition of a psychological construct (guilt, control, altruism). The more precise the definition, the easier it is to choose an appropriate technique to measure that construct. Discusses the Health and Psychosocial Instrument File, a recent measurement database.…

These two curriculum demonstration projects on bilingual readiness in the earliest school years contain many similarities. Both were formed on the thesis that young children can and will learn a second language readily and that the urban classroom mixture of Spanish-speaking, English-speaking, and Negro-dialect speaking children can be capitalized…
