Although counteracting environmental programmes and policies have been strengthened, large oil spills still occur at irregular intervals. The total oil spill costs and their compensations have attracted much interest from various parties, such as local stakeholders, and state and federal...

This paper considers the optimal design problem for multiresponse regression models. The <InlineEquation ID="IEq4"> <EquationSource Format="TEX">$$R$$</EquationSource> </InlineEquation>-optimality introduced by Dette (J R Stat Soc B 59:97–110, <CitationRef CitationID="CR5">1997</CitationRef>) for single response experiments is extended to the case of multiresponse parameter estimation. A general equivalence theorem for the <InlineEquation ID="IEq5">...</inlineequation></citationref></equationsource></inlineequation>

In Penna's single-species asexual bit-string model of biological ageing, the Verhulst factor has too strong a restraining effect on the development of the population. Danuta Makowiec gave an improved model based on the lattice, where the restraining factor of the four neighbours take the place...

Since the construction of new socialist countryside, "agriculture, rural areas and farmers" have been in the pivotal development period. As the all-around transition and progress of our society, water conservancy construction and other rural public facilities and services seriously lag behind,...

From the point of view of agricultural civilization, the history of human civilization is the history of the development of the agricultural civilization. Accompanied by social progress and development of the times, the function of agriculture also experiences the expansion and deepening. In...

Current situations of water conservancy development in China include: water shortage and serious water pollution; total water reservoir capacity is large but most are dangerous reservoirs; wide distribution and directly serving the broad masses; business is comprehensive and many fields are...

This paper reports on the development of a two-dimensional, fully nonlinear CFD (Computational Fluid Dynamics) model with dynamic mesh to analyze the performance of a heave-only floating OWC (oscillating water column) device. The model was validated against previous experimental, analytical and...

We aim to make two contributions to the literature on the effects of transaction costs on financial price volatility. First, by using a research design with three ingredients (a common set of companies simultaneously listed on two stock exchanges; binding capital controls; different timing of...

This paper analyses a game theoretic model of tax competition in a system where tax authorities are revenue optimisers and countries are differentiated by size. The model accommodates more than two countries. In equilibrium, larger countries set higher tax rates non-cooperatively. By applying...

The positive relation between stock price changes and trading volume (price–volume relationship) as a stylized fact has attracted significant interest among finance researchers and investment practitioners. However, until now, consensus has not been reached regarding the causes of the...
