However, relatively few studies consider what makes an effective signal, in terms ...

Deep, ground based, optical wide-field supernova searches are capable of detecting a large number of supernovae over a broad redshift range up to z ∼ 1.5. While it is practically unfeasible to obtain spectroscopic redshifts of all the supernova candidates right after the discovery, we show that the magnitudes and colors of the host galaxies, as well as the supernovae, can be used to select high...

SYNOPSIS. Studies on color patterns of fishes have focused on relationships between bright, relatively permanent colors, such as those of fishes inhabiting coral reef and tropical freshwater habitats, and ecological factors, such as competitors, predators, and the visual background. By comparison, the functions of, and hence the selective pressures acting on, temporary changes in nuptial colora...

In 2 experiments, we examined whether the stimulus equivalence instructional paradigm could be used to teach relations among names, definitions, causes, and common treatments for disabilities using a selection-based intraverbal training format. Participants were pre- and posttested on vocal intraverbal relations and were trained using multiple-choice worksheets in which selection-based intraver...

aesthetic equivalence is produced when both the source and target texts enjoy the same degree of interpretability with semantic explicitness. this requires both texts to have the same number of indeterminacies. roman ingarden, the polish phenomenologist and aesthetician, was the first one to consider the concept of indeterminacy as a characteristic of literary works. then iser and jauss, two ae...

A few colors, such as red and yellow, are commonly found in aposematic (warning) signaling across taxa, independent of evolutionary relationships. These colors have unique traits (i.e., hue, brightness) that aid in their differentiation, and perhaps, their effectiveness in promoting avoidance learning. This repeated use calls into question the influence of selection on specific warning colors a...
