N-C3N4/BiOClxI1-x S-type heterojunctions were fabricated by electrostatic self-assembly, BiOClxI1-x nanosheets with radius of 22nm stacked at surface of g-C3N4. The doping of elements reduced the band gap of g-C3N4 from 2.90eV to 2.03eV, the charge carriers were generated by the transfer of...

Seasonal price premiums have been proposed as a means of dampening the highly seasonal patterns of milk production in Florida. A Markov decision bio-economic model of the breeding and replacement decisions was solved via stochastic dynamic programming and used to analyze the potential supply...

Data from the International Comparison Project are used to analyze the development of the real gross domestic products (GDPs) of the G-7 countries from 1950-1988. For the group as a whole, per capita GDP increased almost threefold in this period, whereas the inequality among the seven countries...

A multiple indicator and multiple cause model with dichotomous indicators was used to study consumer's perception toward orange juice. Results indicate that recalls of orange juice advertising messages by the respondent had a positive impact on his/her perception toward orange juice. Results...

A mixed demand system is developed using the fundamental matrix equation of demand theory. The model parameterization combines the parameterizations of the quantity- and price- dependent Rotterdam models. The relationship between the mixed-demand-model parameters and the underlying direct and...

"Commodity promotion" consists of many activities, each designed to contribute to a consumer's product knowledge or influence tastes. However, both knowledge and tastes are unobservable, or latent, variables influencing demand. This paper specifies a dynamic structural model of fresh fruit...

Despite the rapid rise in complex carbohydrate consumption over the last twenty-five years, fresh potato consumption has fallen by over 50%. Fresh potato growers and retailers alike need to know whether these changes reflect consumer responses to changing relative prices or incomes, or whether...
