Integration and the performance of large-scale health enterprises : field studies of psychological health delivery systems in the U.S. Military
(Massachusetts Institute of Technology, 2012)
Large-scale health enterprises comprise multiple organizations that provide programs and services for patients. Despite the interconnectedness of these systems there is a lack of empirical research documenting how these ...
Unintended effects of changes in NIH appropriations : challenges for biomedical research workforce development
(Massachusetts Institute of Technology, 2012)
The U.S. government doubled NIH appropriations between 1998 and 2003, aiming to significantly foster research activities in biomedicine. However, several indicators demonstrate not only that the impact of the budget increase ...
Working towards a future on alternative fuels : the role of the automotive industry
(Massachusetts Institute of Technology, 2012)
Complementarity of vehicles and fuels has posed significant barrier for increasing the use of alternative fuels in place of traditional ones. An initial positive number of either alternative fuel vehicle (AFV) users or ...
Acceptance by proxy : analyzing perceptions of hydraulic fracturing to better understand public acceptance for geologic storage of carbon dioxide
(Massachusetts Institute of Technology, 2015)
Carbon capture and storage (CCS) represents an important pathway for reducing greenhouse gas emissions in order to mitigate climate change. However, there is significant uncertainty about how the technology will be accepted ...
Unexpected consequences of demand response : implications for energy and capacity price level and volatility
(Massachusetts Institute of Technology, 2014)
Historically, electricity consumption has been largely insensitive to short term spot market conditions, requiring the equating of supply and demand to occur almost exclusively through changes in production. Large scale ...
Heavy-duty diesel vehicle Nox̳ aftertreatment in 2010 : the infrastructure and compliance challenges of urea-SCR
(Massachusetts Institute of Technology, 2008)
Increasingly stringent heavy-duty vehicle emission regulations are prompting the use of PM and NOx aftertreatment systems in the US, the EU and Japan. In the US, the EPA Highway Diesel Rule, which will be fully implemented ...
Process based cost modeling of emerging optoelectronic interconnects : implications for material platform choice
(Massachusetts Institute of Technology, 2008)
Continuously increasing demand for processing power, storage capacity, and I/O capacity in personal computing, data network, and display interface suggests that optical interconnects may soon supplant copper not only for ...
Evaluation of the environmental viability of direct injection schemes for ocean carbon sequestration
(Massachusetts Institute of Technology, 2008)
This thesis evaluates the expected impact of several promising schemes for ocean carbon sequestration by direct injection of CO2, and serves as an update to the assessment by Auerbach et al. (1997) and Caulfield et al. ...
Combining a renewable portfolio standard with a cap-and-trade policy : a general equilibrium analysis
(Massachusetts Institute of Technology, 2009)
Most economists see incentive-based measures such a cap-and-trade system or a carbon tax as cost effective policy instruments for limiting greenhouse gas emissions. In actuality, many efforts to address GHG emissions combine ...
Uncertainty analysis of capacity estimates and leakage potential for geologic storage of carbon dioxide in saline aquifers
(Massachusetts Institute of Technology, 2009)
The need to address climate change has gained political momentum, and Carbon Capture and Storage (CCS) is a technology that is seen as being feasible for the mitigation of carbon dioxide emissions. However, there is ...
