浅谈高校后勤社会化的财务核算

随着高校后勤改革的不断深入，高校后勤将逐渐从学校脱离，成为相对独立的经济实体，而原有高校的财务管理核算体制已不适应后勤改革的需要。     

受约聚甲醛的热力学性质研究

采用旋转异构体模型，将受约束聚甲醛(POM)长链等效为约束在圆柱体内，用完全计算法研究受约的聚甲醛链的热力学性质，发现体系的配分函数Z与链长N存在关系：lnZ=aN b，其中N也代表键的数目，a和b仅与温度T和无限长圆柱体的直径D有关．这种方法为研究多链体系的热力学提供一种近似方法。

Technical Notes ：STUDIES ON THE VALUE OF SECONDARY MARKET TO THE SUPPLY CHAIN

This paper investigates the impact of a secondary market, where retailers can buy and sell excessinventories, on the supply chain. We develop a two-period model with a single manufacturer and tworetailers. At the beginning of the first period the retailers order and receive products from themanufacturer, but at the beginning of the second period, they can trade surplus products betweenthemselves in the secondary market. We investigate the impact of the correlated dependence ofretailers' demand on both the quantity effect and the allocation effect under the secondary market.Lastly,we study potential strategies for the manufacturer to increase sales with the existence of thesecondary market.     

FROM MANUFACTURING SCHEDULING TO SUPPLY CHAIN COORDINATION：THE CONTROL OF COMPLEXITY AND UNCERTAINTY

With time-based competition and rapid technology advancements, effective manufacturingscheduling and supply chain coordination are critical to quickly respond to changing marketconditions. These problems, however, are difficult in view of inherent complexity and variousuncertainties involved. Based on a series of results by the authors, decomposition and coordination byusing Lagrangian relaxation is identified in this paper as an effective way to control complexity anduncertainty.A manufacturing scheduling problem is first formulated within the job shop context withuncertain order arrivals, processing times, due dates, and part priorities as a separable optimizationproblem. A solution methodology that combines Lagrangian relaxation, stochastic dynamicprogramming, and heuristics is developed. Method improvements to effectively solve large problemsare also highlighted. To extend manufacturing scheduling within a factory to coordinate autonomicmembers across chains of suppliers, a decentralized supply chai     

Subset threshold autoregression

We develop in this paper an efficient way to select the best subset threshold autoregressive model. The proposed method uses a stochastic search idea. Differing from most conventional approaches, our method does not require us to fix the delay or the threshold parameters in advance. By adopting the Markov chain Monte Carlo techniques, we can identify the best subset model from a very large of number of possible models, and at the same time estimate the unknown parameters. A simulation experiment shows that the method is very effective. In its application to the US unemployment rate, the stochastic search method successfully selects lag one as the time delay and five best models from more than 4000 choices.

高校后勤社会化改革的法律风险及其防范

由于高校后勤社会化模式的混乱,使后勤社会化改革中出现了一系列法律风险。为防范该风险,应在全国实行统一的后勤社会化改革模式——专门机构负责模式,即采用“外部采办”的方式,并通过相关的制度设计来规范高校后勤服务实体的运作。
