A new research tool developed by an interdisciplinary team of psychologists and economists could help social scientists more accurately evaluate how well individuals and society are faring. The method offers a new way to characterize the daily life experience of individuals, aimed at providing a measure that could be used in assessing social interventions, including clinical trials. Its developers are working on a way to use the method in calculating a "National Well-Being Account," to provide a broad measure of the well-being of people of all ages, akin to the economic measure Gross Domestic Product.
The tool, called the Day Reconstruction Method (DRM), assesses how people spend their time and how they feel about, or experience, activities throughout a given day. In a trial of the new technique, a group of women rated the psychological and social aspects of a number of daily activities. Among these women, relaxing with friends was one of the most enjoyable activities, and the least enjoyable was commuting.
DRM is described by Daniel Kahneman, Ph.D., a professor of Psychology and Public Affairs at Princeton University, and colleagues in the December 3, 2004, issue of Science. Dr. Kahneman was joined in this study by his Princeton University colleague, economist Alan B. Krueger, and psychologists David A. Schkade of the University of California, San Diego, Norbert Schwarz of the University of Michigan, and Arthur A. Stone of Stony Brook University.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
