It has been documented that adolescent mothers are less verbally and emotionally responsive in their interactions with their children compared to adult mothers. These less than optimal adolescent mother/infant interactions have been found to affect the child's healthy growth and development. This small study aimed to identify and characterize the frequency of verbal behaviors exhibited in the i...

OBJECTIVE High-performance marine craft personnel (HPMCP) are regularly exposed to vibration and repeated shock (VRS) levels exceeding maximum limitations stated by international legislation. Whereas such exposure reportedly is detrimental to health and performance, the epidemiological data necessary to link these adverse effects causally to VRS are not available in the scientific literature, a...

We describe a program to assist in designing oligonucleotide probes on the basis of protein alignments and the codon usage of the target organism. If necessary, the input sequences can be weighted to neutralise the effect of closely similar sequences or to bias the output in favour of a particular taxon.

Exhaustive global array data flow analysis for communication optimization is expensive and considered to be impractical for large programs. This paper proposes a demand-driven analysis approach that reduces the analysis cost by computing only the data flow information related to optimizations. In addition, the analysis cost of our scheme can be effectively managed by trading space for time or c...

Several authors have hypothesized that visuo-spatial working memory is functionally analogous to verbal working memory. Irrelevant background speech impairs verbal short-term memory. We investigated whether irrelevant visual information has an analogous effect on visual short-term memory, using a dynamic visual noise (DVN) technique known to disrupt visual imagery (Quinn & McConnell, 1996b). Ex...

Numerical abilities are thought to rest on the integration of two distinct systems, a verbal system of number words and a non-symbolic representation of approximate quantities. This view has lead to the classification of acalculias into two broad categories depending on whether the deficit affects the verbal or the quantity system. Here, we test the association of deficits predicted by this the...

UNLABELLED We sought to replicate and extend Carroll and Hesse's (1987) study of the acquisition of tacts by including participants with and without developmental disabilities. As in Carroll and Hesse, the present results showed that mand-tact training, rather than tact-only training, led to more rapid acquisition of tacts. Tacting on follow-up tests did not differ. In addition, our results sho...

We evaluated the emergence of untaught second-language skills following directly taught listener and intraverbal responses. Three preschool children were taught first-language (English) listener responses (e.g., "Point to the horse") and second-language (Welsh) intraverbal responses (e.g., "What is horse in Welsh?" [ceffyl]). After intervention, increases in untaught second-language tacts (e.g....

covering arrays of strength two have been widely studied as combinatorial models of software interaction test suites for pairwise testing. while numerous algorithmic techniques have been developed for the generation of covering arrays with few columns (factors), the construction of covering arrays with many factors and few tests by these techniques is problematic. random generation techniques c...
