Neuroeconomics has the potential to fundamentally change the way economics is done. This article identifies the ways in which this will occur, pitfalls of this approach, and areas where progress has already been made. The value of neuroeconomics studies for social policy lies in the quality, replicability, and relevance of the research produced. While most economists will not contribute to the neuroeconomics literature, we contend that most economists should be reading these studies.
Accuratemeasurements of X-ray attenuation coefficients for Si and Ge have been used to determine those dispersion corrections which are related to the photoeffect cross section. The results are compared with calculations based on relativistic as well as nonrelativistic quantum mechanics. A new notation is proposed to facilitate the comparison between experimental and theoretical results.
The potentialities of photographic transaxial tomographic methods are discussed. It is shown that unfiltered, transaxial tomographic summation images can yield high-quality tomograms of high-contrast objects. A direct and efficient photographic method for recording transaxial tomograms (grazing incidence tomography) is demonstrated, and various means for analog filtering are discussed. Grazing incidence tomography allows for high geometrical resolution for high- or medium-contrast objects. The present contrast performance is an order of magnitude different to that of computerised tomography, but an improvement of the method seems possible.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
