Modelling ecosystem adaptation and dangerous rates of global warming.

We are in a period of relatively rapid climate change. This poses challenges for individual species and threatens the ecosystem services that humanity relies upon. Temperature is a key stressor.

Policy implications of first-dollar coverage: a qualitative examination from the payer perspective.

Objectives: Immunization against potentially life-threatening illnesses for children and adults has proved to be one of the great public health successes of the 20th century and is extremely cost-effective. The Patient Protection and Affordable Care Act includes a number of provisions to increase coverage and access to immunizations for the consumer, including a provision for health plans to cover all Advisory Committee on Immunization Practices-recommended vaccines at first dollar, or without cost sharing. In this study, we examined payers' perspectives on first-dollar coverage of vaccines and strategies to improve vaccination rates.

Use of emergency departments for conditions related to poor oral healthcare: implications for rural and low-resource urban areas for three states.

Persistent and worsening shortages of oral healthcare providers in rural areas, combined with limited acceptance of Medicaid and State Children's Health Insurance Programs, have left many patients without adequate access to dental care. Evidence suggests that such patients seek treatment in emergency departments (EDs) for problems that might have been prevented given adequate oral healthcare. This finding has public policy questions that are explored by this study.
