三春好雨润田园--访辽宁省农业经济委员会主任万福民

辽宁农业经过多年的快速发展已由相对滞后变为撑起经济半壁江山的支柱产业。然而,农民丰产不收,负担过重等问题仍很严重,如何让农民收入不断增加、工农各业统筹发展,协调城市乡村利益关系、共同建设小康社会,已成为农民的迫切期望和各级政府关注的焦点问题。     

增强邓小平理论课教学时效性的切几点

应该选好切入点,与时俱进地增强邓小平理论课的教学时效性。课堂讲授的重要切入,应以学生为中心,抓兴奋点,预留老师“答记者问”时间,精心设计讨论;实践参与的重要切入,则在于联系改革实际的典型事例,注重用参观,社会调查等方式增强学生的社会责任感和判断力。     

论金融危机预警系统的构建

建立健全金融危机的预警系统是有效防范金融危机并弱化其影响的重要手段。建立金融危机预警系统具有很大的必要性同时也是可行的。国外金融危机预警研究方法对构建金融危机预警系统的思路和策略具有借鉴意义。     

财务弹性与企业投资的关系研究

基于现金持有量的视角,在采用中位数法、拟合值法、三分位数法等三种方法对财务弹性作出界定的基础上,考察了财务弹性与企业投资之间的关系。结果表明,通过持续持有足够现金而保持财务弹性的企业,其投资水平会显著提高。并对企业持续持有较多现金是否是因为面临融资约束或公司治理不佳所致作出了检验,实证结果进一步支持持续储备较多现金是企业秉持财务弹性策略的结果。研究结果意味着财务弹性也是影响我国企业投融资决策的一个重要因素。     

A new two-party bargaining mechanism

If resources and facilities from different partners need to be engaged for a large-scale project with a huge number of tasks, any of which is indivisible, decision on the number of tasks assigned to any collaborating partner often requires a certain amount of coordination and bargaining among these partners so that the ultimate task allocation can be accepted by any partner in a business union for the project. In the current global financial crisis, such cases may appear frequently. In this paper, we first investigate the behavior of such a discrete bargaining model often faced by service-based organizations. In particular, we address the general situation of two partners, where the finite Pareto efficient (profit allocation) set does not possess any convenient assumption for deriving a bargaining solution, namely a final profit allocation (corresponding to a task assignment) acceptable to both partners. We show that it is not appropriate for our discrete bargaining model to offer the union only one profit allocation. Modifying the original optimization problem used to derive the Nash Bargaining Solution (NBS), we develop a bargaining mechanism and define a related bargaining solution set to fulfil one type of needs on balance between profit-earning efficiency and profit-earning fairness. We then show that our mechanism can also suit both Nash’s original concave bargaining model and its continuous extension without the concavity of Pareto efficient frontier on profit allocation.     

Real-time part dispatching within manufacturing cells using fuzzy logic

A new fuzzy logic dispatching method is presented ff which o ers an improvement over certain existing common dispatching rules with respect to the performance measures, number of late parts, maximum part lateness, average producff tion times and machine bu er levels. The fuzzy logic dispatcher incorporates a wider range of scheduling issues than those considered by most dispatching rules, considers certain control ff issues that e ect scheduling, contains mechanisms for optimization and also allows for the addition of more control or scheduling rules.     

<红楼梦>:文化的寓言

《红楼梦》以一群“正邪两赋”的“人格”形象及其各种各样爱情的足迹，展现出一幅如诗如画的“玉堂金马红楼梦”中的生活画卷，从而以“滑稽”与“庄严”同在的宗教意识作为这一“生活”的“衰草枯杨好了歌”。“假语村言”敷衍出的一段故事，概括起的却是一部真实的文化史和一次审美意义上的文化批判，具有一种“文化结论”的意义，从而成为中国文化的一个“寓言”。     

用干涉滤波技术实现图象边缘增强

本文提出了用干涉及滤波技术实现图象边缘增强的一种新方法。将同一物体的一张正确对焦的透明片与另一张离焦的透明片重叠放在透镜的前面,在单色平行光照射下,在透镜的后焦面上得到两图象的谱的干涉,通过对干涉条纹的适当滤波,可在输出面得到边缘增强的象。     

洋葱内表皮细胞骨架的显示及部分性质研究

本文利用洋葱内表皮细胞作为实验材料，观察细胞骨架结构．实验结果显示植物细胞骨架呈网状结构，分布在整个细胞质中；幼嫩细胞的细胞骨架比较密集，吸附较多蛋白质，须经多次洗涤后才可获得较为清晰的图片．进一步的研究表明，与幼嫩细胞的细胞骨架相比，衰老细胞的细胞骨架出现部分解聚的现象；幼嫩细胞的细胞骨架在低温条件下亦出现解聚现象．使用洋葱内表皮观察细胞的骨架结构为我们在简便、经济的条件下，通过普通光学显微镜观察骨架提供了可能．这种方法为今后进一步开展细胞骨架的功能研究奠定了基础．     

我国区域工业竞争力的测定与评价——我国十大沿海城市工业的广义竞争力实证比较研究

本文认为竞争力应该不仅仅是从“争”的角度来理解,更应该从“和而不同”的角度来理解,即广义竞争力,“竞合力”或者说广义上的竞争力才是提升工业竞争力的关键所在。正是基于这种广义竞争力的新视角,本文采用了两种不同的竞争力测定方法,对沿海十大城市的工业竞争力进行了实证比较研究。
