despite the fact that the contents of items on the raven's progressive matrices have little similarity to the content of subjects taught in school, the correlation coefficients between iq scores and achievement test scores have been estimated to be about 0.5. six groups of 20 students were randomly selected from the first, second, and third grades of urban and rural guidance schools in sha...

We examined the influence of the availability of human food on the distribution and foraging habits of the Common raven (Corvus corax), in yosemite national Park, California. the raven arrived and established itself as a year-round resident in yosemite in the 1960s, and its population has been increasing ever since. Surveys of nine sites with varying levels of human influence in yosemite sugges...

This paper applies judgment and decision making research to collaborative problem solving. This analysis is done with respect to the Raven and CoRaven decision-making tools for filtering, interpreting, and visualizing large amounts of uncertain data in the domain of intelligence analysis. Raven and CoRaven are multimodal advisory decision aids and their inferential reasoning is based on Bayesia...

A new troglomorphic spider from caves in Central Java, Indonesia, is described and placed in the ctenid genus Amauropelma Raven, Stumkat & Gray, until now containing only species from Queensland, Australia. Only juveniles and mature females of the new species are known. We give our reasons for placing the new species in Amauropelma, discuss conflicting characters, and make predictions about the...

The correlation between a measure of working memory capacity (WMC) (Operation Span) and a measure of fluid abilities (Raven Advanced Progressive Matrices) was examined. Specifically, performance on Raven problems was decomposed by difficulty, memory load, and rule type. The results suggest that the relation between Operation Span and Raven is fairly constant across levels of difficulty, memory ...

The antifreeze polypeptide (AFP) from the sea raven, Hemitripterus americanus, is a member of the cystine-rich class of blood antifreeze proteins which enable survival of certain fishes at sub-zero temperatures. Sea raven AFP contains 129 residues with 10 half-cystine residues. We have analyzed these half-cystine residues and established that all 10 of the half-cystine residues appeared to be i...
