This chapter examines the potential environmental impacts associated with denying a renewed operating license (OL) (i.e., the no-action alternative); the potential environmental impacts from electric generating sources other than renewal of the Edwin I. Hatch Nuclear Plant (HNP), Units 1 and 2 OLs; the potential impacts from instituting additional conservation measures to reduce the total deman...

Distributed Generation (DG) in the form of renewable power generation systems is currently preferred for clean power generation. It has a significant impact on the distribution systems. This impact may be either positively or negatively depending on the distribution system, distributed generator and load characteristics. In this works, an overview of DG is briefly introduced. The technology of ...

There is a modern-day hazard, threatening the existence of civilization, from impacts of comets and asteroids larger than 1.5 km diameter. The average annual world fatality rate is similar to that due to significant accidents (e.g., airplane crashes) and natural disasters (e.g., floods), although impact events are much more rare and the deaths per impact event are much greater. (Smaller, more f...

Cumulative effects are the combined effects of multiple activities, and watershed effects are those which involve processes of water transport. Almost all impacts are influenced by multiple activities, so almost all impacts must be evaluated as cumulative impacts rather than as individual impacts. Existing definitions suggest that to be significant, an impact must be reasonably expected to have...

BACKGROUND US adolescents have high rates of teen pregnancy, childbearing, and sexually transmitted infections (STIs), highlighting the need to identify and implement effective programs that will help improve teen sexual and reproductive health. MATERIALS AND METHODS This review identified 103 random-assignment evaluations of 85 programs that incorporated intent-to-treat analyses and assessed...

The rapid increase in oil prices has spurred intense interest in alternative energy sources, with biofuels being one of the more debated and controversial alternatives. In the United States, existing and proposed biofuel policies and the increased price of oil have led to a rapid expansion of ethanol supply. With U.S. federal government policies like the Renewable Fuel Standard (RFS) in the Ene...

Climate variability and trends impact on Australia’s economy, environment and society. Australian research organisations are conducting many research projects to understand the magnitude of climate change (including natural variability and human induced climate change) and the physical drivers that underpin our ability to forecast and manage its impacts. Australia’s average temperature varies b...

Heterogeneous Impacts in PROGRESA The “common effect” model in program evaluation assumes that all treated individuals have the same impact from a program. Our paper contributes to the recent literature that tests and goes beyond the common effect model by investigating impact heterogeneity using data from the experimental evaluation of the Mexican conditional cash transfer program PROGRESA. Ou...
