Examining the intention-behavior gap: The impact of the food environment on the eating behaviors of low-income African American women

The current study investigated environmental barriers to the intention-behavior gap. The food environment was examined as a moderator between motivation for healthy living and actual eating behavior. A sample of 55 low-income African American women (Mage = 30.25, SD = 7.46) completed self-report motivation and eating behavior questionnaires. The food environment was measured by the number and proportion of healthy and unhealthy food retailers in one’s neighborhood using ArcGIS mapping software. The results showed that greater motivation was associated with less unhealthy eating when there was relatively equal access to nearby unhealthy and healthy food retailers. When given both options, in the context of high motivation, individuals may be more likely to decline unhealthy foods consisting of high amounts of oils, fats, and sugars. A combination of motivational interventions and innovative food policy and urban planning initiatives may be needed to promote healthier communities

Nonlinear electron-phonon coupling in doped manganites

We employ time-resolved resonant x-ray diffraction to study the melting of charge order and the associated insulator-metal transition in the doped manganite Pr$_{0.5}$Ca$_{0.5}$MnO$_3$ after resonant excitation of a high-frequency infrared-active lattice mode. We find that the charge order reduces promptly and highly nonlinearly as function of excitation fluence. Density functional theory calculations suggest that direct anharmonic coupling between the excited lattice mode and the electronic structure drive these dynamics, highlighting a new avenue of nonlinear phonon control
