While these comparisons have revealed ways in which are and not representative general population, variations among samples drawn from received less attention. This article focuses on whether sample varies a function time. Specifically, we...
Background: Clinical trials of anti-Aβ monoclonal antibodies in Alzheimer disease (AD) infer target engagement from Aβ positron emission tomography (PET) and/or fluid biomarkers such as cerebrospinal (CSF) Aβ42/40.However, these measure deposits indirectly incompletely.In contrast, postmortem neuropathologic assessments allow direct investigation treatment effects on brain and many other pathologic features.Methods: From a clinical trial dominantly inherited AD, we measured...

Prevailing economic models of consumer behavior completely ignore the well-documented link between context and evaluation. We propose test a theory that explicitly incorporates this link. Changes in one group's spending shift frame reference defines consumption standards for others just below them on income scale, giving rise to expenditure cascades. Our model, descendant James Duesenberry's relative hypothesis, predicts observed ways which individual savings rates respond changes both own...

ABSTRACT Researchers often want to increase the broader societal impact of their work. One way do that is discuss research findings directly with practitioners. Yet, such interactions are voluntary and not regularly arise, which raises a key demand question: Under what conditions practitioners connect researchers?
