Evaluation of sentence perception of adults with hearing loss when using a video teleconferencing system

This study evaluate the speech perception of hearing-impaired adults (with varying degrees of deafness) when using a video teleconferencing system (an integrated service digital network).

Activities development for 2 word combinations on pre-sentence level TAGS

This paper presents activities to assist teachers of hearing impaired students to develop 2-word combinations for use in instruction in conjunction with the Teacher Assessment of Grammatical Structures Pre-Sentence Level (TAGS-P). The paper presents activity procedures and materials to guide teachers in teaching 2-word combinations.

The Developmental Sentence Analysis and the Grammatical Analysis of Elicited Language - Complex Level: a correlative study

This paper studies the Developmental Sentence Analysis (DSA), which measures syntactic maturity of spontaneous utterances, and the Grammatical Analysis of Elicited Language (GAEL), which uses a highly structured set of games and activities designed to elicit specific target sentences.

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.

A cost-effective high-throughput digital system for observation and acquisition of animal behavioral data

We have designed and implemented a low-cost digital system using closed-circuit television cameras coupled to a digital acquisition system for the recording of in vivo behavioral data in rodents and for allowing observation and recording of more than 10 animals simultaneously at a reduced cost, as compared with commercially available solutions. This system has been validated using two experimental rodent models: one involving chemically induced seizures and one assessing appetite and feeding. We present observational results showing comparable or improved levels of accuracy and observer consistency between this new system and traditional methods in these experimental models, discuss advantages of the presented system over conventional analog systems and commercially available digital systems, and propose possible extensions to the system and applications to nonrodent studies.
