Bio-E10 is short for the biofuel made up of 90% gasoline in volume and 10% bio-ethanol, which is the ethanol made from commercially-grown crops such as corn and wheat by the sugar fermentation process. In China, bio-E10 will be supplied nationwide from 2020 as an alternative to conventional...

Based on the survey data of 150 peasant households in typical Karst mountainous area in the year 2009, causations, characteristics and influence factors of the concurrent-business behavior of peasant households during planting structure adjustment are analyzed. Result shows that there is...

On-demand service platform that offers diverse service classes has allowed consumers to hail all the available services simultaneously and wait for an assignment. Such a probabilistic service-hailing mode has been widely adopted in practice, however, whether it always performs better than the...

The influence of pre-stretching prior to artificial ageing on microstructure, tensile properties, and fatigue behavior of AA2099-T8 plates were investigated. The results showed that increased pre-strain level from 1% to 6% resulted in more uniform distribution and increasing density of the T1...

The two most influential models in delay discounting research have been the exponential (E) and hyperbolic (H) models. We develop a new methodology to design binary choice questions such that exponential and hyperbolic discount rates can be purposefully manipulated to make their rate parameters...

We train a deep learning model to predict countries’ Gini index from individuals’ cultural values assessed in the World Values Survey. When presented with a new set of respondents, the model’s predicted Gini index correlated highly with the actual Gini index. Feature importance analyses...

The paper presents an unusually comprehensive empirical comparison of delay discounting/intertemporal choice models. A three-component model is developed, with power laws modeling subjective time, subjective money, and magnitude sensitivity. It nests several other models in the literature, among...

We examine the confounding between models of intertemporal choice. Critical outputs from hyperbolic, exponential and arithmetic discounting are all highly multicolinear in commonly used research designs. This confounding means that if one model defines a participant as impulsive, they all will:...
