Case study: acquisition of Japanese in aural language by the four year old child whose hearing loss was detected when he was visiting in U. S. with his family

Access to thesis is restricted. Contact Archives and Rare Books. This paper reports the results of language training for a newly diagnosed hearing impaired Japanese child using methods from the CID parent-infant program.

Temporal processing in listeners with unilateral hearing loss

Temporal processing is examined for sounds delivered to the intact ear of individuals with unilateral hearing, and delivered to one ear of individuals with normal, bilateral hearing. Two temporal processing skills are assessed: 1) the ability to detect sinusoidal amplitude modulation of a wide-band noise, for various modulation frequencies, and 2) the just-noticeable-difference for temporal complexity of random-spectrogram-sounds.

Workers' compensation for occupational hearing loss: what we know or don't know

This papers looks at workers' compensation laws for each state to determine if there have been any updates in the laws since a 2000 survey by Dobie and Megerson. The study also examines what information is available to audiologists testing patients in workers' compensation claims.

Effect of unilateral hearing loss on the speech-evoked auditory brainstem response in the presence of noise

Speech-evoked auditory brainstem responses (ABRs) were acquired in quiet and in the presence of noise at two study sessions to investigate 1) test-retest variability and 2) subcortical representation of speech stimuli. Participants were adults with normal hearing in both ears who listened monaurally and adults with unilateral deafness. Results indicate consistency in responses across sessions and several differences between hearing groups for magnitudes of discrete components.

Outcomes of conventional amplification for pediatric unilateral hearing loss

Although some children with unilateral hearing loss (UHL) are at-risk for educational difficulties and behavioral problems, research in treatment outcomes for pediatric UHL is limited. The objective of this study was to examine the benefits of a conventional hearing aid in children with mild to moderately severe UHL, using speech perception measures and subjective assessments from the child, parent, and teacher.

An analysis of the effect of audiologic management on a newborn hearing screening program's refer and loss to follow-up rates

This study includes an exhaustive review of the literature related to universal newborn hearing screening and loss to follow-up. It examines refer and follow-up rates in Missouri and highlights three successful newborn hearing screening programs under the same audiologic management.

Efficacy of a combined drug therapy for ameliorating noise-induced hearing loss

Experiments investigated the median effective dose of antiepileptic drugs and synthetic glucocorticoids for the prevention and treatment of noise-induced hearing loss for C57BL/6J mice. We also tested the possible synergistic effects of combining drugs from the two drug families.

An Estimate of Nest Loss in Canada Due to Industrial Forestry Operations

Annual loss of nests by industrial (nonwoodlot) forest harvesting in Canada was estimated using two avian point-count data sources: (1) the Boreal Avian Monitoring Project (BAM) dataset for provinces operating in this biome and (2) available data summarized for the major (nonboreal) forest regions of British Columbia. Accounting for uncertainty in the proportion of harvest occurring during the breeding season and in avian nesting densities, our estimate ranges from 616 thousand to 2.09 million nests. Estimates of the impact on numbers of individuals recruited into the adult breeding population were made based on the application of survivorship estimates at various stages of the life cycle. Future improvements to this estimate are expected as better and more extensive avian breeding pair density estimates become available and as provincial forestry statistics become more refined, spatially and temporally. The effect of incidental take due to forestry is not uniform and is disproportionately centered in the southern boreal. Those species whose ranges occur primarily in these regions are most at risk for industrial forestry in general and for incidental take in particular. Refinements to the nest loss estimate for industrial forestry in Canada will be achieved primarily through the provision of more accurate estimates of the area of forest harvested annually during the breeding season stratified by forest type and Bird Conservation Region (BCR). A better understanding of survivorship among life-history stages for forest birds would also allow for better modeling of the effect of nest loss on adult recruitment. Finally, models are needed to project legacy effects of forest harvesting on avian populations that take into account forest succession and accompanying cumulative effects of landscape change.
