We take three types of tidal marshes in Shanghai City as the study object: tidal marshes in mainland, tidal marshes in the rim of islands, and shoal in Yangtze estuary. On the basis of assessing nutrient quality and environmental quality, respectively, we use soil quality index (SQI) to assess...

Since the Chinese government's rapid increase in expenditure on science and technology (S&T) during the 2000s, numerous related policies have been implemented by national-, provincial-, city-, and prefecture-level governments in China. Each level of government aims to promote innovation...

In the presence of temptation and self-control preferences as in Gul and Pesendorfer, the optimal policy is to subsidize savings when consumers are tempted by "excessive" impatience (Krusell, Kuruscu and Smith, 2010). However, in the homogeneous agents model, taxation loses an important property...

To achieve a goal of reducing the emission intensity of carbon dioxide in 2020 by 40–45% relative to 2005 in China, the framework for a low-carbon scenario was developed on a small scale in Minhang District, Shanghai. The STIRPAT model was employed to reveal the factors that contribute to CO2...

This paper proposes a mathematical model of multidirectional associative memory (MAM) neural network with almost periodic coefficients and continuously distributed delays. By using exponential dichotomy and spectral radius, a sufficient condition for the existence and the global exponential...

Parkinson’s disease (PD) is a common disease of the central nervous system among the elderly, and its complex symptoms bring up challenges for the clinical diagnosis. In this paper, a new method based on a polar coordinate system with varying origin was proposed in order to quantitatively...

Horn (1988) proved a necessary and sufficient condition for the stochastic ordering of an arbitrary folded normal variable and a standard folded normal variable. This paper studies the more general case and presents the necessary and sufficient conditions for the stochastic ordering of two...

This paper studies monopoly extraction of a nonrenewable resource with the presence of a competitively supplied capacity constrained renewable substitute. The monopolist staves off the renewable supply when the latter becomes competitive and then lets the resource price jump up.

Within the confines of linear tax and complete market, we show that the efficiency force for a negative capital tax may not be strong enough to reverse the politico-economic force for a positive redistributive taxation under temptation and self-control preferences.
