Spelling errors in children who are deaf

This is a descriptive study that analyzes the spelling abilities as well as a specific spelling error made by children between the ages of 5 and 9 who are deaf and wear cochlear implants.

Tactile errors of localization on the sternums of tactaid VII users and non-users

This paper discusses a study done to test tactile errors of localization abilities, with and without a Tactaid VII communication aid.

Common errors made by clinic patients responding to the W-22 and NU-6 word lists

This paper presents a study of common errors made during speech discrimination testing.

Dialogue journals: A non-threatening way to correct written language errors

The goals of the present study are: to determine if dialogue journals are an effective activity within a balanced literacy program to improve on written language errors in students who are deaf and hard of hearing.

An analysis of grammatical errors by children with cochlear implants

Spontaneous writing samples of deaf children with cochlear implants were analyzed for syntactic errors and other descriptive characteristics. These results were compared to a small sample of writings from hearing children.

Correlated observation errors in data assimilation

Data assimilation provides techniques for combining observations and prior model forecasts to create initial conditions for numerical weather prediction (NWP). The relative weighting assigned to each observation in the analysis is determined by its associated error. Remote sensing data usually has correlated errors, but the correlations are typically ignored in NWP. Here, we describe three approaches to the treatment of observation error correlations. For an idealized data set, the information content under each simplified assumption is compared with that under correct correlation specification. Treating the errors as uncorrelated results in a significant loss of information. However, retention of an approximated correlation gives clear benefits.

Improvements to the accuracy of measurements of NO2 by zenith-sky visible spectrometers II: errors in zero using a more complete chemical model

Using a flexible chemical box model with full heterogeneous chemistry, intercepts of chemically modified Langley plots have been computed for the 5 years of zenith-sky NO2 data from Faraday in Antarctica (65°S). By using these intercepts as the effective amount in the reference spectrum, drifts in zero of total vertical NO2 were much reduced. The error in zero of total NO2 is ±0.03×1015 moleccm−2 from one year to another. This error is small enough to determine trends in midsummer and any variability in denoxification between midwinters. The technique also suggests a more sensitive method for determining N2O5 from zenith-sky NO2 data.
