华南地区浅圆仓控温气调储粮技术应用新思路

控温和氮气气调储粮技术是绿色环保综合储粮的重要技术,随着20世纪末国家一批新建粮库的竣工投产,国内粮食储藏条件得到改善,尤其是仓房防潮、隔热、控温、气密等仓储性能得到显著提高。中央储备粮广东新沙港直属库借中储粮总公司氮气气调扩大应用项目推广之机率先在国内浅圆仓开展了氮气气调储藏玉米的试验,通过实验,论证了氮气气调对虫害防治、霉菌抑制和脂肪酸值控制方面效果显著,氮气气调储粮技术的应用对改善保管人员工作条件,降低劳动强度,提高工作效率优势明显,初步得出华南地区浅圆仓使用控温和氮气气调综合技术储藏玉米安全可行,社会、经济等综合效益显著。     

当前扩大投资对价格总水平的影响分析

本文首先阐述了中央实施扩大投资的主要背景及具体措施,并运用历史比较分析的方法,在对改革开放以来几次投资过热、1998—2002年应对亚洲金融危机扩大投资对价格总水平的影响进行深入剖析的基础上,从投资结构和基础产业产能状况、上游产品价格和下游产品市场供求比较、市场预期情况、国际市场价格影响等几个方面对此次扩大投资对价格总水平的影响进行了深入分析,并进一步指出当前更好地落实扩大投资政策必须密切关注的几个重大问题。最后,结合我国实际情况,从加强投资调控和引导、努力扩大居民消费、积极稳妥推进价格改革、加强价格监测预测预警和市场监管等几个方面提出政策建议。

生态工业园是为响应我国可持续发展要求而建立、基于循环经济理论和产业生态学原理的一种新型工业园区。本研究通过构建生态工业园经济、资源、环境与社会复合系统的评价指标体系,采用经济社会发展与资源环境协调发展度评价模型,并根据协调发展度等级标准,分析评价了大连经济技术开发区生态工业园区2001—2010年经济社会与资源环境协调发展度。     

财务管理专业《内部控制学》课程的教学改革方案设计

在我国当前内部控制的教学模式相对落后、教学改革几乎空白的背景下,本文以四川师范大学商学院财务管理专业为依托,针对《内部控制学》课程的教学内容制定了“实践模拟教学体系”,为保证教学目标的实现构建了“组合式教学法”.灵活多样的教学方法相互融合且交替使用于不同的教学内容中,由此设计出一套完整严密的教学改革总体方案.     

Traveler preferences from online reviews: Role of travel goals,class and culture

Along with being critical performance indicators as well as a rich source of information for potential customers, the overall rating and recommendation behavior also work as a crucial information source for managers of airlines for customer segmentation, service design, and post-purchase evaluation management. In this study, we explore how customer preferences, behavior and post-purchase evaluations differ for travelers depending on their respective travel goals, travel class, and the culture of their native country. Based on the frameworks of the construal level theory and expectation disconfirmation theory, we provide a psychological explanation of why specific service attributes, categorized in process-outcome and tangible—intangible dimensions, get higher importance than others for a particular set of customers. We analyzed consumer review data of 28,341 reviews for 345 airlines by customers from 132 countries. The results yielded critical theoretical contributions to extant literature on airline evaluations and recommendations, construal levels, airline customer segmentation, etc. Moreover, the results also helped managers of an airline to package design, segment customers, enhance targeted communication, and customer relationship management overall. The limitations and future scope of the study have also been discussed.     

A supply chain coordination mechanism with suppliers’ effort performance level and fairness concern

The interest conflict is an important factor affecting the supply chain (SC) performance, so it is very important to set up a reasonable coordination mechanism to eliminate the SC conflicts. Considering the fact that suppliers' effort performance level and fairness concern behavior are important factors affecting SC performance, we can develop SC models to analyze and compare SC decisions under the centralized decision and decentralized decision, and then we design a SC coordination mechanism through cost sharing. The results show that the designed coordination mechanism can effectively solve the conflict problem of SC, mobilize SC members’ motivation and initiative without damaging their profits, and realize the long-term cooperation between the retailer and multi-suppliers. It also can achieve the Pareto improvement and the sustainable development of SC.     

Coordinating under incomplete information

We show that, in a minimum effort game with incomplete information where player types are independently drawn, there is a largest and smallest Bayesian equilibrium, leading to the set of equilibrium payoffs (as evaluated at the interim stage) having a lattice structure. Furthermore, the range of equilibrium payoffs converges to those of the deterministic complete information version of the game, in the limit as the incomplete information vanishes. This entails that such incomplete information alone cannot explain the equilibrium selection suggested by experimental evidence. We thank Atila Abdulkadiroglu, Hans Carlsson, Ani Guerdjikova and an anonymous referee for helpful comments. Part of this work was done while Asheim was visiting Cornell University, which hospitality is gratefully acknowledged.     

Fiscal Policy in the New Open Economy Macroeconomics and Prospects for Fiscal Policy Coordination

Abstract.  This paper reviews the literature on the effects of fiscal policy in new open economy macroeconomics (NOEM) models, complementing it with additional results that attempt to clarify the importance of the exchange rate regime (fixed or flexible) and of the type of policy (balanced budget or debt‐financed). Fixed exchange rates only seem to postpone the costs from the short to the long run, but the type of policy is crucial in determining the welfare impact of fiscal expansions. The paper also reviews the recent literature on fiscal policy coordination and shows that there is already some evidence that the gains from coordination in this area can be potentially large but draw attention to the need for reflecting more on the role of fiscal policy as a stabilization tool and on possible interactions between fiscal and monetary policy.     

Competition and coordination in experimental minority games

This work presents experimental results on a coordination game in which agents must repeatedly choose between two sides, and a positive fixed payoff is assigned only to agents who pick the minoritarian side. We conduct laboratory experiments in which stationary groups of five players play the game for 100 periods, and manipulate two treatment variables: the amount of information about other players’ past choices and the salience of information regarding the game history (i.e., the length of the string of past outcomes that players can see on the screen while choosing). Our main findings can be summarized as follows: aggregate efficiency in the game is in most cases significantly higher than the level corresponding to the symmetric mixed strategy Nash equilibrium. In addition, providing players with information about individual choices in the group does not improve aggregate efficiency with respect to when such information is absent. Displaying information about more rounds than just the previous one, on the other hand, seems to have a positive effect on aggregate efficiency. At the individual level, we find a stronger statistical relation between players’ current choices and their own past choices than between players’ choices and previous aggregate outcomes. In addition, the depth of the relation between present and past choices seems to be affected by the prompt availability of information about the game history. Finally, we detect evidence of a mutual co-adaptation between players’ choices over time that is partly responsible for the high level of efficiency observed.
