We provide estimates of expenditure and price elasticities of the demand for imported milk in Spain using a dynamic Linear Approximate of the Almost Ideal Demand System (LA-AIDS). We also provide evidence of structural change in the demand for imported milk in Spain due to the dairy program...

BP neural network with optimum hidden layer nodes were used to evaluate the power environmental issues in China. Furthermore, Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method is used to optimise the number of hidden layer nodes of BP neural network. The evaluation...

Existing literature suggests that people's cognitive styles vary significantly across nations and cultures, and that East Asians emphasize holistic information processing and are more receptive to transformational advertising than people in the West.

Based on the transposon-mutagenized library of Pantoea agglomerans BH18, mutant screens were conducted to obtain the strain with the highest Fe (III) reduction and hydrogen production. Of these transposon-mutagenized mutants, the mutant strain TB230 was screened for high Fe (III)-reducing...

Based on survey data of current situations of new generation migrant workers’ vocational education and its influence on social mobility in Shijiazhuang City, the author believes that there are many drawbacks in vocational education of new generation migrant workers, including low...

The RIETI inventor survey, which was conducted in 2007, invited inventors to contribute their views and opinions on the constraints on the R&D performance of their organizations, and the policies and managerial agenda for improving it. A total of 1,300 inventors (around one quarter of those who...

Carpooling in the US has a storied history. After experiencing a peak 20% mode share in 1980, the current share of carpooling for work trips is about 10% and the majority of these carpooling trips are made by intra-household members. Casting the choice between SOV and carpool as a social dilemma...

The effects of fuel price on travel demand for different income groups reveal the choices and constraints they are faced with. The first purpose of this study is to understand these underlying choices and constraints by examining the variation of fuel price elasticity of vehicle miles travelled...
