Efficacy of high-frequency tympanometry in infants birth to six months of age: A pilot study

The purpose of this study was to assess the use of 1 kHz tympanometry in young infants. A larger sample will be needed to develop definitive norms and determine the sensitivity and specificity of 1 kHz tympanometry for middle ear pathology in young infants.

Does experience in creative art influence the written self-expression of the deaf child?

This paper discusses whether participation in creative art affects the hearing impaired child's self expression in written language.

How the listener's experience influences the rating of the intelligibility of hearing-impaired children's speech

This paper discusses the importance of listener experience as a factor when developing intelligibility measures for hearing impaired children.

Efficacy of 1000 Hz tympanometry in infants birth to 4 months of age: A follow up study

Interpretation of 1000 Hz tympanometry is not standardized. Several compensated and uncompensated measures were analyzed and compared to otologic findings. Results of auditory brainstem testing and otoacoustic emissions were considered to better obtain middle ear status. Findings were inconclusive due to small sample size.

ABR as a predictor of neurodevelopment in very low birth weight neonates

This paper discusses a study to determine whether the neonatal ABR predicts neurodevelopmental delays in low birth weight infants.

Seeing things: perception, experience and the constraints of excavation

Recent attempts to problematize archaeological fieldwork concerned with excavation at the expense of surface survey, and with questions of procedure more than interpretations of the past. In fact these two kinds of fieldwork offer quite different possibilities and suffer from different constraints. Thought must be given to ways in which they can be combined if they are to make a real contribution to social archaeology. The argument is illustrated by a project carried out at a megalithic cemetery in Scotland.

Refashioning local government and inner-city regeneration: The Salford experience

This paper explores the role of local government in urban regeneration in England. The first part describes local-central government relations during recent decades. It concludes that 'actually occurring' regeneration fuses top-down and bottom-up priorities and preferences, as well as path dependencies created by past decisions and local relations. The second part illustrates this contention by examining the regeneration of inner-city Salford over a 25-year period. It describes Salford City Council's approach in achieving the redevelopment of the former Salford Docks and how this created the confidence for the council to embark on further regeneration projects. Yet the top-down decision-making model has failed to satisfy local expectations, creating apathy which threatens the Labour government's desire for active citizens in regeneration projects.

Watching the infant brain learn words: Effects of vocabulary size and experience

Previous investigations comparing auditory event-related potentials (ERPs) to words whose meanings infants did or did not comprehend, found bilateral differences in brain activity to known versus unknown words in 13-month-old infants, in contrast with unilateral, left hemisphere, differences in activity in 20-month-old infants. We explore two alternative explanations for these findings. Changes in hemispheric specialization may result from a qualitative shift in the way infants process known words between 13 and 20 months. Alternatively, hemispheric specialization may arise from increased familiarity with the individual words tested. We contrasted these two explanations by measuring ERPs from 20-month-old infants with high and low production scores, for novel words they had just learned. A bilateral distribution of ERP differences was observed in both groups of infants, though the difference was larger in the left hemisphere for the high producers. These findings suggest that word familiarity is an important factor in determining the distribution of brain regions involved in word learning. An emerging left hemispheric specialization may reflect increased efficiency in the manner in which infants process familiar and novel words. (c) 2004 Elsevier Inc. All rights reserved.
