(2022-03-08)The risks posed by Lead (Pb), a persistent, bioaccumulative, and toxic heavy metal, to individuals through drinking water garnered increased attention in response to the contamination crisis in Flint, Michigan (beginning ... -
Drivers and Points of Intervention for Obesity and Food Insecurity
(2021-07-12)Poor nutrition is a leading cause of disease and death in the United States and around the world. Two key types of poor nutrition are food insecurity (a lack of reliable access to nutritious food) and obesity (excess ... -
Drivers of Long-Term Variability in Amazon Forest Carbon Fluxes
(2017-05-03)Amazon forests are potentially an important sink of atmospheric carbon dioxide (CO2). However, the present magnitude of net CO2 uptake by intact Amazon forests and the controls upon seasonal, yearly, and decadal variability ... -
Drivers of Physician Productivity and Performance: The Role of Queuing Systems, Relative Performance Feedback, and Cohort Turnover
(2017-02-10)This dissertation investigates how operational choices about the design of work systems in health care settings impact the way physicians deliver care. Across three studies, I examine the following potential drivers of ... -
Drone-Based VOC Sampling System for Atmospheric Insights in the Amazon
(2017-11-27)Produced mainly through natural emission from vegetation (~1015 grams a year), volatile organic compounds (VOCs) in influence climate through their involvement in photochemistry, such as the production of ozone in the ... -
Drop-Based Microfluidics for Biological Applications
