Burnout and depression across the career life cycle of healthcare providers are increasing at alarming rates. We need to devote our resources and efforts to bolster the next generation of healthcare providers who have the capacity for resiliency and well-being--the antidote to burnout and depression. A handful of organizations have implemented general wellness programs to combat burnout but there are surprisingly few documented, well-researched interventions to build resiliency. Wellness provides an alternative framework to approach the epidemic rates of burnout and depersonalization within the healthcare profession. In this article we describe our rationale for developing a culture of wellness among primary care physicians along with the specific activities and initiatives for creating a culture of wellness throughout medical educational training. Examples of the four core components of a residency wellness program-concrete resources, positive conversations, curriculum, and control-are described with regard to our Family Medicine Residency. A brief description of early efforts to empirically examine the impact of the wellness initiative across systemwide residency programs (Family Medicine and other programs) is described.

A rheological method to assess the diffusion behavior of liquids in molten polymers above their boiling point is presented in this article. The evaporation of the liquid and the evolution of the blends complex modulus are followed by rheological measurement. Identification of the Fick's diffusion coefficient and the rate of evaporation of butylmethacrylate in low density polyethylene is done. The values of the diffusion coefficient are in agreement with those obtained by classical methods. The method developed here appears as complementary to the existent ones. It allows the measurement of diffusion coefficient of liquid/polymer system at high temperatures even for volatiles liquids.

This article reports a rheological and morphological study of poly(vinyl chloride) (PVC) that was subjected to a treatment capable of decreasing the simultaneous mass transfers occurring between liquid food (or simulant) and PVC packaging. The storage modulus (GЈ), loss modulus (GЉ), and the loss angle (tan ␦), have been used to determine the glass transition temperature using a Rheometric Scientific Dynamic Analyzer. Young's modulus was measured on a dynamometer, and a morphological characterization was carried out with an optical microscope. The obtained results show that treated PVC behaves like a composite material, which is in agreement with a previously established model.
