Increased population pressure and political decisions have led to more intensive agricultural practices in China. As in other regions of the world, these practices can damage natural capital. We use the Kalman filter and Chinese panel data to estimate an index of environmental productivity...

Y-SBA-15 was synthesied by doping Yttrium (Y) into SBA-15 using a solvent-free solid-state grinding method, and 1-butyl-3-methylimidazolium phosphomolybdic salt ([Bmim] 3 PMo 12 O 40 , abbreviated to [Bmim]PMoO ) was synthesized, and then it was loaded on Y-SBA-15. [Bmim]PMoO/Y-SBA-15 is a...

Constructed wetlands are extensively applied in waste water treatment and water ecosystem restoration. However, the accumulation and migration characteristics and potential ecology risks of heavy metals, particularly in a long-running large-scale constructed wetland for wastewater treatment, are...

In this paper, we study consumer search in a housing market subject to objective frictions induced by intermediaries and psychological frictions intrinsic to in tenants themselves. Using rental data from a leading real estate brokerage company during 2016 and 2018, we find a unimodal...

This paper studies the aftermath of “unsuccessful” antidumping investigations that failed to achieve positive antidumping findings or antidumping duties against foreign exporters. While these investigations may be viewed as benign, “unsuccessful” investigations may nonetheless elevate...

As a new generation of electrode material, flexible electrode material can effectively broaden the application area and scope of energy storage devices. In this paper, a new vanadium pentoxide carbon fiber cloth (V 2 O 5 -CFC) is successful synthesized by means of electrospinning and...

The likelihood and amount of money transferred back and forth between parents and their adult children in the United States in 1988 are examined in this study. Using the 1989 Survey of Consumer Finances, conducted for the Federal Reserve Bank, this study finds that 13 percent of families made...

Lot streaming is the process of splitting a production lot into sublots, and then, scheduling the sublots in an overlapping fashion on the machines. In this paper, we present a polynomial-time procedure for determining the number of sublots of a single-lot, multiple-machine flow shop...
