Asset prices are determined by investors’ risk preferences and by the distributions
of assets’ risky future payments. Economists refer to these two bases
of prices as investor "tastes" and the economy’s "technologies" for generating
asset returns. A satisfactory theory of asset valuation must consider how individuals
allocate their wealth among assets having different future payments.
This chapter explores the development of expected utility theory, the standard
approach for modeling investor choices over risky assets....
Senile plaques, the invariable hallmark and likely proximal
cause of Alzheimer’s disease (AD), are structured deposi-tions of the 40- and 42-residue forms of the Abpeptide.
Conversely, diffuse plaques, which are not associated with
neurodegeneration, consist mainly of unstructured Ab42.
We have investigated the interaction between Ab40 and
Ab42 through an assay, which involves labeling both vari-ants with an environment-sensitive fluorophore.
Major treatment decisions are made on the basis of whether a tumor is classified as a small cell lung carcinoma (SCLC) or as one of the non-small cell lung cancer (NSCLC) varieties (squamous, adenocarcinoma, large cell carcinoma, bronchioloalveolar carcinoma, and mixed versions of these).
