Increasing energy efficiency and exploiting energy saving potential are two important practices that can help to ensure future energy security in China. This paper proposes a new total factor energy efficiency indicator, based on the directional meta-frontier data envelopment analysis (DEA)...

In the paper, the concept of circulation industrial chain of distinctive agricultural products is introduced. By using the e-commerce platform, the new industrial chain for the circulation of distinctive agricultural products on the basis of online transaction is established. In view of the...

We investigate intraday seasonality in, and relationships between, informational efficiency, volatility, volume and liquidity. Platinum and gold, both traded in overlapping sessions in Tokyo and New York, provide an interesting comparison because Tokyo is an internationally important trading...

A latent heat thermal energy storage (LHTES) system, which uses phase change materials (PCMs) as thermal storage medium, has attracted interests over the past decades due to its high energy storage density. However, a computationally efficient heat transfer model, which is essential for...

The efficient removal of arsenic from wastewater is still a challenge. In this paper, a heterojunction consisted of in-situ carbon-doped TiO2 and nitrogen deficiency g-C3N4 (C/TiO2@ND-C3N4) has been constructed, which can completely oxidize As(III) (10,000 μg/L, 40 mL) to As(V) within 12 min...

Controlling the shape, morphology, and porosity of hollow nanostructures is a pivotal issue for adjusting the characteristics of tailor-made nanomaterials to expand their application to more fields. Although many hollow metal oxides have been developed, studies on the construction of hollow...

For years, anecdotal evidence has suggested increased fertility rates resulting from catastrophic events in an area. In this paper, we measure this fertility effect using storm advisory data and fertility data for the Atlantic and Gulf Coast counties of the United States. We find that...

One of the most notable social phenomena in China is the large urban-rural disparity. There are many studies of it, but most of them focus on income or earnings inequality. In this paper, we investigate the consumption disparity between urban and rural households in China from 1988 to 2002. Our...
