Coal-burning power plants have been the largest unregulated source of mercury emissions in the United States, sending 48 tons of mercury into the air annually. In 2005, the U.S. Environmental Protection Agency promulgated its Clean Air Mercury Rule (CAMR), requiring coal-fired power plants to reduce their mercury emissions by approximately 20% beginning in 2010. Numerous states are already requ...
The International Maritime Organization (IMO) Marine Environment Protection Committee (MEPC) and some countries have gradually strengthened the laws regulating ship exhaust emissions. The aim of this paper is to estimate the impact of an after-treatment technology exhaust gas cleaning (EGC) system on marine diesel engine emissions and the cost advantage compared to using low-sulfur fuel oil. Th...
BACKGROUND In developing countries such as Pakistan, poor training of mid-level cadres of health providers, combined with unregulated availability of labour-inducing medication can carry considerable risk for mother and child during labour. Here, we describe the exposure to labour-inducing medication and its possible risks in a vulnerable population in a conflict-affected region of Pakistan. ...
Unlike exhaust emissions, non-exhaust traffic emissions are completely unregulated and in addition, there are large uncertainties in the non-exhaust emission factors required to estimate the emissions of these aerosols. This study provides the first published results of direct measurements of size resolved emission factors for particles in the size range 0.25–2.5 μm using a new approach to deri...
In this paper, we examine the intersection between two important aspects of climate policy design. The first is the point of regulation. Should it be placed on pollution sources, carbon-rich inputs, or consumers? This issue of upstream versus downstream regulation is one that we will refer to as vertical targeting. The second aspect concerns the external effects of a local climate policy. Leaka...
Climate policies such as carbon taxes or cap-and-trade programs are increasingly used to reduce emissions. In the United States, Regional Greenhouse Gas Initiative (RGGI) program is this paper, I use detailed state-level data estimate impact of RGGI on coal and natural gas consumption in electric-power industry. find directly caused phase-outs within regulated states. Specifically, decreased fo...
The concept of buying an organization's computing needs on a pay-as-you-go basis is known as Utility Computing. In this model, organizations pay for the usage of applications, either to Information Technology (IT) departments or to an external technology vendor. This approach is similar to the way consumers pay for utility services like electricity, gas, and water. Though the Utility Computing ...
BACKGROUND Audit with feedback is a moderately effective approach for improving professional practice in other health care settings. Although unregulated caregivers give the majority of direct care in long-term care settings, little is known about how they understand and perceive feedback reports because unregulated providers have not been directly targeted to receive audit with feedback in qua...
