Use of zero-inflated count data models is common in applications where the number of zero counts exceeds that predicted from a traditional count data model such as Poisson or negative binomial. When count data exhibiting inflated zero counts are correlated among subjects, a natural approach will...

The marine industry plays an important role in promoting the development of the blue economic zone, and the study of the operating performance of marine industry is of important practical significance. Using DEA method, this article measures the operating performance of marine industry in the...

Based on carbon emission data of 17 cities in Shandong Province in 2005-2009, this paper analyzes carbon emission economic efficiency. It conducts weight distribution by the Ordered Weighted Averaging (OWA) method, and takes systematic evaluation on carbon emission economic efficiency using...

This article is based on the imbalance state of China's marine industries, focuses on how to evaluate and calculate marine industries’ development level, and to enhance the comprehensive competitiveness. Based on the present situation of China’s marine industries, we construct the...

We show that as compared to the case of no lobbying and the case of domestic lobbying, the domestic-foreign lobbying may achieve the lowest tariff and...</p>

Based on 16 in-depth case studies this paper argues that the internationalisation behaviour of indigenous Chinese private-owned firms can only be partially explained by the Uppsala model and the theory of international new ventures. Instead, the so-called "bounded entrepreneurship" may be the...

Using density functional theory with a semiempirical van der Waals approach proposed by Grimme, the adsorption behavior of carbon monoxide on a gold monolayer supported by graphene or monolayer hexagonal boron nitride has been investigated. Based on the changes in the Dirac cone of graphene and...

We investigate field effect transistors (FETs) based on semiconducting armchair-edged silicene nanoribbons (ASiNRs) by using ab initio quantum transport calculations. These FETs have high performance with an I <Subscript>on</Subscript>/I <Subscript>off</Subscript> ratio of over 10<Superscript>6</Superscript> and a subthreshold swing as small as 90 mV/decade....</superscript></subscript></subscript>
