优化分析条件,提高微库伦法测定硫含量准确度

0 前言 伴随着油品质量的进一步升级,我国对石油产品的硫含量提出了严格的控制指标.为此,建立一个快速、准确测定石油产品中硫含量的分析方法对于石油产品的质量控制非常重要.现有比较成熟经典的方法是管式炉法(GB/T387)、氧弹法(GB/T388)、燃灯法(GB/T380)等,但是测定仪器复杂、步骤繁多、费时费力,无法实现自动化,难以满足现代工业生产的高速检验需要.

Case characteristics affecting the method of grievance dispute settlement

In 1986, we reported the results of an attempt to model the inner, workings of grievance arbitration. We concluded that the primary determinant of whether or not a grievance is settled privately or through arbitral award is the degree of private, outside legal representation. This article extends that work. Utilizing a more sophisticated statistical technique with a better specified list of explanatory variables, it identifies two additional grievance case characteristics that influence the method of grievance settlement: case complexity and type of dispute. The probability of an arbitrated settlement is greatest where the issue is simple and involves discipline and where the parties are represented by private, outside attorney advocates.     

Effective and equitable supply of gasoline to impacted areas in the aftermath of a natural disaster

The focus of this research is on supplying gasoline after a natural disaster. There are two aspects for this work: determination of which gas stations should be provided with generators (among those that do not have electric power) and determination of a delivery scheme that accounts for increased demand due to lack of public transportation and considerations such as equity. We develop a mixed integer program for this situation. Two case studies based on Hurricane Sandy in New Jersey are developed and solved in CPLEX. As expected, increasing equity increases cost and also tends to place generators to stations with large initial inventories. It is further observed that CPLEX can solve the largest instances of the problem for a 5% tolerance gap, indicating that the model is efficient.

Gasoline prices,transport costs,and the U.S. business cycles

The effects of gasoline prices on the U.S. business cycles are investigated. In order to distinguish between gasoline supply and gasoline demand shocks, the price of gasoline is endogenously determined through a transportation sector that uses gasoline as an input of production. The model is estimated for the U.S. economy using five macroeconomic time series, including data on transport costs and gasoline prices. The results show that although standard shocks in the literature (e.g., technology shocks, monetary policy shocks) have significant effects on the U.S. business cycles in the long run, gasoline supply and demand shocks play an important role in the short run.

Estimating the effect of a gasoline tax on carbon emissions

Recently the proposal has been made to raise gasoline taxes in the United States to curb carbon emissions. The existing literature on the sensitivity of gasoline consumption to changes in price may not be appropriate for evaluating the effectiveness of such a tax. First, most of these studies fail to address the endogeneity of gasoline prices. Second, the responsiveness of gasoline consumption to a change in tax may differ from the responsiveness of consumption to an average change in price. We address these challenges using a variety of methods including traditional single‐equation regression models, estimated by least squares or instrumental variables methods, and structural vector autoregressions. Our preferred approach exploits the historical variation in US federal and state gasoline taxes. Our most credible estimates imply that a 10‐cent per gallon increase in the gasoline tax would reduce carbon emissions from vehicles in the United States by about 1.5%.

Anticipation,Tax Avoidance,and the Price Elasticity of Gasoline Demand

Least‐squares estimates of the response of gasoline consumption to a change in the gasoline price are biased toward zero, given the endogeneity of gasoline prices. A seemingly natural solution to this problem is to instrument for gasoline prices using gasoline taxes, but this approach tends to yield implausibly large price elasticities. We demonstrate that anticipatory behavior provides an important explanation for this result. Gasoline buyers increase purchases before tax increases and delay purchases before tax decreases, rendering the tax instrument endogenous. Including suitable leads and lags in the regression restores the validity of the IV estimator, resulting in much lower elasticity estimates. Copyright © 2016 John Wiley & Sons, Ltd.
