Renewable Portfolio Standards (RPSs) are one of the most prevalent and impactful clean energy policies implemented by states in the United States. This paper investigates the regional spillover effect of RPS policies using a directed dyad panel dataset of renewable electricity generation in US states from 1991 to 2021. Regional spillover effect is measured in two ways: by considering the influence of an RPS enacted in neighboring states and in states in the same regional transmission organization or independent system operator region.

Existing studies often assume that relocated plants produce the same or higher emissions when relocated. However, the current pollution mitigation policies enforce even higher emission standards in the destination after plant relocation.

Localized carbon reduction strategies are especially critical in states and regions that lack top-down climate leadership. This paper illustrates the use of coupled systems in assessments of subnational climate solutions with a case study of Georgia, a state located in the southeastern United States that does not have statewide climate goals or plans. The paper illustrates how robust place-specific plans for climate action could be derived from foundational global and national work and by embedding that research into the context of socio-ecological-technological systems.

However, few robust and comprehensive analyses are available that lay out how US states and regions can most effectively contribute. This paper describes an approach developed for Georgia-a state in the southeastern United States called "Drawdown Georgia", our research involves (1) understanding Georgia's baseline carbon footprint and trends, (2) identifying the universe of Georgia-specific carbon-reduction solutions that could be impactful by 2030, (3) estimating the greenhouse gas reduction potential of these high-impact 2030 solutions for Georgia, and (4) estimating associated costs and benefits while also considering how the solutions might impact societal priorities, such as economic development opportunities, public health, environmental benefits, and equity.

The methodology involves the development of input-output (I-O) bills of goods that characterize how energy-efficiency funds would be spent across sectors of the economy. The methodology builds on and adds greater articulation to the research conducted in prior studies of U.

Traditionally, genetic testing was conducted in outpatient clinics, with stepwise genetic testing occurring over several years. This delayed the time to diagnosis, making it more difficult to include underrepresented groups, such as those who identify as Black and Latinx.

To inform regional responses to climate change, decision-makers need credible and relevant information representing a wide swath of knowledge and perspectives. The southeastern U.

While high-resolution remote sensing has proven promising for carbon mapping in highly fragmented urban landscapes, data cost and availability are the major obstacle prohibiting accurate, consistent, and repeated measurement of forest carbon pools in cities. This study aims to evaluate the uncertainties of forest carbon estimation in response to the combined impacts of remote sensing data resolution and neighborhood spatial patterns in Charlotte, North Carolina.

The relative benefits of electric trucks depend heavily on vehicle efficiency associated with drive cycle, diesel fuel price, travel demand, electric drive battery replacement and price, electricity generation and transmission efficiency, electric truck recharging infrastructure, and purchase price. For a drive cycle with frequent stops and low average speed such as the New York City Cycle (NYCC), electric trucks emit 42-61% less GHGs and consume 32-54% less energy than diesel trucks, depending upon vehicle efficiency cases.

Although degrees offered by DL are often the subject of criticism, the authors' experience has been that learning outcomes have been very good. Nevertheless, a number of challenges and opportunities have been encountered including those associated with flexibility of the program, delivering practice courses at a distance, facilitating interaction, faculty workload and preparation and student support, Newer technologies that may assist in this effort are identified.

Parenteral fish oil was discontinued, and the burr cell anemia disappeared, suggesting that parenteral fish oil might be associated with hemolytic anemia.

The need for improved health status has been a catalyst for much of this effort. This has also driven improvements in the housing and husbandry techniques required to maintain the health status of animals produced or used for biomedical research.

Nursing graduate supervision of theses and projects at a distance is a new experience for many faculties. In our global and mobile society, nursing students frequently seek graduate programs that are geographically distant from their home communities. As options for nursing graduate education through distributive learning become increasingly available, the challenges for faculty to supervise graduate students at a distance pose issues and concerns.

Objectives: Pediatric gastroenterology fellows are expected to acquire skills as clinicians, researchers, and educators. An e-mail survey was conducted to examine training experiences of individual fellows; to understand how graduating fellows rate their abilities as clinicians, researchers, and teachers; and to answer whether the size of a pediatric gastroenterology training program affects a fellow's training and future position choice.
Materials And Methods: A survey was e-mailed to 76 third-year pediatric gastroenterology fellows.
