This study seeks to explore the determinants of the relationship of economic growth and water quality in the United States using an Environmental Kuznets Curve framework. Specifically this study seeks to determine whether there is evidence of improvement in water quality since passage of the 1972 amendments to the Clean...
If the spatial and temporal distribution of resources is not homogenous it creates an assignment problem. While the adoption of individual (or transferable) quota management in many commercial fisheries has resolved issues of over-appropriation, assignment problems may remain due to the spatial and temporal complexity of fisheries resources, which creates...
Phytophthora infestans, the causal agent of late blight disease, has been reported in North America since the mid-nineteenth century. In the United States the lack of or very limited sexual reproduction has resulted in largely clonal populations of P. infestans. In 2010 and 2011, but not in 2012 or 2013,...
Macrosomia is a medical term describing a new baby born with an excessive birth weight (greater than 4000g). Fetal macrosomia may lead to both pregnancy complications, and increased risk of mother's and baby's health problems after birth. But the potential complications may be mitigated by a cesarean delivery. As such,...
BACKGROUND: As it becomes increasingly possible to obtain DNA sequences of orthologous genes from diverse sets
of taxa, species trees are frequently being inferred from multilocus data. However, the behavior of many methods for
performing this inference has remained largely unexplored. Some methods have been proven to be consistent given...
Many experts have argued that the traditional management of commercial fish stocks as single-species is short-sighted, wasteful, and ineffective. Ecosystem-based fisheries management (EBFM) now is being promoted as a potential solution to the problem. While much attention has been directed recently at the potential benefits of implementing EBFM for commercial...
Several behavioral studies have suggested that rarity is critical for enabling irrelevant, salient
objects to capture attention. We tested this hypothesis using the N2pc, thought to reflect
attentional allocation. A cue display was followed by a target display in which participants
identified the letter in a specific color. Experiment 1...

Michigan’s State Department of Education issued a resolution in 2003 calling for all public K-12 schools to repeal their American Indian mascots and in 2013 the Michigan Department of Civil Rights filed a complaint with the United States Department of Education in response to school districts failing to do so....
Feedback loops involving soil microorganisms can
regulate plant populations. Here, we hypothesize that microorganisms
are most likely to play a role in plant–soil feedback
loops when they possess an affinity for a particular plant and
the capacity to consistently affect the growth of that plant for
good or ill. We...
Renewable energy, particularly wind power, has increased dramatically over the past two decades. In the Pacific Northwest, the power system has accommodated a large amount of new wind power. The variability of wind power has introduced many challenges, requiring additional reserve generation to be available to maintain system stability. The...
Amplification was regarded, since the early days of quantum theory, as a mysterious ingredient that
endows quantum microstates with macroscopic consequences, key to the “collapse of the wave packet,”
and a way to avoid embarrassing problems exemplified by Schrödinger’s cat. Such a bridge between the
quantum microworld and the classical...
The research presented herein represents an effort to combine the ultra-smooth surface of an amorphous metal thin film (AMTF) with a solution-processed dielectric synthesized via prompt inorganic condensation (PIC).
