Something very odd was going on in the corner of my patio. An earthworm apparently hovering an inch above ground. Its wriggling did not, however, seem to be generating any levitational force, so how could it have freed itself from gravity? Closer inspection (with reading glasses now on) revealed that this actually no at all, but something far more interesting, and certainly not flying. Iberian ...

Auditory streaming is a fundamental perceptual component of auditory scene analysis. It manifests itself in the everyday ability of humans and animals to parse complex acoustic information arising from multiple sound sources into meaningful auditory “streams”. While seemingly effortless, the neural mechanisms underlying auditory streaming remain a mystery largely because experiments in non-huma...

Although moral dilemmas such as the trolley and footbridge dilemmas (Thomson, 1986) have been widely employed to investigate the nature of moral reasoning, but their psychometric properties remain a mystery. In this study, 219 participants completed 62 moral dilemma tasks used in Greene et al. (2001), and the correlation structure among the dilemmas was analyzed through factor analysis and stru...

framed in a cognitive approach to task-supported l2 vocabulary learning, the present study used a pedagogical approach to investigate the relative effectiveness of tasks with different involvement loads on the vocabulary knowledge of iranian efl learners. the goal was to investigate the way that the construct of involvement load is related to the input hypothesis (krashen, 1985) and the output ...

Mutant mice lacking the integrin alpha8 subunit exhibit variable defects in kidney development with most mutants missing both kidneys. Several lines of evidence indicate that the known extracellular matrix ligands for integrin alpha8beta1 are either dispensable for or not involved in alpha8beta1 signaling during kidney development. This suggests the presence of an unknown ligand. A novel alpha8...

Conventional project-management tools--PERT charts and Gantt charts, for example--were created to help manage sequences of discrete tasks that make up large construction projects. Yet these tools don't capture clearly the back-and-forth of information that takes place in innovative processes, such as product development. Conventional tools are designed to answer the question, "What other tasks ...
