background and purpose: diabetes is the most common metabolic disorder which is caused by defects in insulin secretion, insulin action, or both .the most important factor in managing diabetes is self-care. since diabetes self-care behaviors are multifactorial and these factors may directly or indirectly affect self-care, it is possible through the application of path analysis to estimate the di...

BACKGROUND Modeling childhood body mass index (BMI) trajectories, versus estimating change in BMI between specific ages, may improve prediction of later body-size-related outcomes. Prior studies of BMI trajectories are limited by restricted age periods and insufficient use of trajectory information. METHODS Among 3,289 children seen at 81,550 pediatric well-child visits from infancy to 18 yea...

[1] Measurements of ice elevation from the Geoscience Laser Altimeter System (GLAS) aboard the Ice, Cloud, and Land Elevation Satellite can be combined with time-variable geoid measurements from the Gravity Recovery and Climate Experiment (GRACE) satellite mission to learn about ongoing changes in polar ice mass and viscoelastic rebound of the lithosphere under the ice sheet. We estimate the ac...

Energy efficiency policies are pursued as a way to provide affordable and sustainable energy services. Efficiency measures that reduce energy service costs will free up resources that can be spent in the form of increased consumption—either of that same good or service or of other goods and services that require energy (and that have associated emissions). This is called the rebound effect. The...
