We investigated whether brain activity was predictive of future reading skill and, if so, how this brain-behavior correlation informs developmental models of reading. A longitudinal study followed 26 normally developing human children ranging in age from 9 to 15 years who were initially assessed for reading skill and performed a rhyming judgment task during functional magnetic resonance imaging...

Marriage matching functions are used to study how marital patterns change when population supplies change. A behavioral marriage matching function with spillover effects is used to rationalize marriage and cohabitation behavior in contemporary Canada. The model non-parametrically identifies the systematic gains to marriage and cohabitation for a couple relative to remaining single. These gains ...

The best ground-based astronomical sites in terms of telescope sensitivity at infrared and submillimeter wavelengths are located on the Antarctic Plateau, where high atmospheric transparency and low sky emission are obtained because of the extremely cold and dry air; these benefits are well characterized at the South Pole station. The relative advantages offered by three potentially superior si...

Most of life’s decisions involve risk and uncertainty regarding whether reward or loss will follow. Decision makers often face not only about the likelihood outcomes (what are chances that I get a raise if ask my supervisor? What supervisor be upset with me for asking?) but also magnitude (if do raise, how large it be? If gets upset, bad consequences me?). Only few studies have investigated eco...

The best ground-based astronomical sites in terms of telescope sensitivity at infrared and sub-millimetre wavelengths are located on the Antarctic plateau – where high atmospheric transparency and low sky emission are observed due to the extremely cold and dry air; these benefits are well characterised at the South Pole station. The relative advantages offered by three potentially superior site...

Using a well-known utility of wealth function, the classic contingent claims model is shown to produce measures of expected wealth, certainty equivalence, gains from trade, and risk premia with relative entropy interpretations, as measured by the KullbackLiebler discrepancy. Author

Humans are well used to appreciating the beauty of flowers, and breeding them to heighten their attractions but we remain largely ignorant of their seeds, something that can also be of stunning beauty, although often on an microscopic scale. A new book, Seeds: Time Capsules of Life, hopes to help redress this perception and raise awareness of conservation issues at a time of unprecedented press...
