The nuclear collective motion

Current developments in nuclear structure are discussed from a theoretical perspective. First, the progress in theoretical modeling of nuclei is reviewed. This is followed by the discussion of nuclear time scales, nuclear collective modes, and nuclear deformations. Some perspectives on nuclear structure research far from stability are given. Finally, interdisciplinary aspects of the nuclear many-body problem are outlined

The Economics of Health and Vitamin Consumption

We estimate the impact of vitamin supplement intake, lifestyle, health indicators, food culture, and demographics on diet quality outcomes as measured by the Healthy Eating Index–2005 (HEI). Our data consists of U.S. adults who participated in the 2003–2004 National Health and Nutrition Examination Survey. Alternative instrumental variable estimators explicitly address issues of endogeneity and complex sample design. Our empirical analysis demonstrates that diet quality is strongly interrelated with food culture. We suggest that vitamin consumption serves as another marker for healthy eating. This finding emphasizes the need to employ economic modeling when developing public policy to reduce obesity
