基于人工神经网络的地铁施工招标综合评估模型

广州地铁工程是国内数个重要的大型城市基础建设项目之一。目前对于这种复杂的大型工程项目,迫切需要一个成熟可靠的公开招标评估系统。根据广州地铁工程的实际招标评标数据,提出应用人工神经网络(ANN)建立地铁施工招标综合评估模型。BP神经网络具有很强的自学习和自适应能力,可以精确地迫近复杂的非线性动态函数。经过训练网络,基于BP网络的模型成功量化了主观和定性的技术评估指数,得出较满意的评估结果。该模型可以通过增加样本提高精度,从而应用在地铁和其他类似建设项目招标中。

苏俄在中东铁路问题上对华政策演变(1917-1924年)

1917-1924年苏俄对华政策演变是从世界革命理想向维护国家利益的现实转变.在中东铁路问题的解决过程中,当时的国际形势、苏俄国内形势、北京政府的阶级立场和中国混乱的政局,都影响着中东铁路问题的解决.     

公诉转自诉制度问题

公诉转自诉制度实质上是被害人对公诉机关公诉权的制约问题，我国选择的制约方式是公诉转自诉，即在特定条件下将公诉案件转化为自诉案件的一种制度。1997年以后的司法实践证明该制度的司法程序不能顺利进行，被害人的利益无法得到保护。所以笔者建议以被害人司法审查制度代替公诉转自诉制度。

我国财政收支划分的立法研究

财政收支划分是财政管理体制的重要组成部分.在市场经济体制下,财政收支划分立法有利于政府职能的履行和公共财政的运行,是完善分税制财政管理体制的丛然要求.完整的财政收支划分法律制度应当由财政级次划分、财政收支分类、财政支出划分和财政收入划分等制度构成.     

The new logic of Japan's young generations

Through daily use of computer games and advanced cartoonized learning, the lower teen generation in Japan has developed an unprecedented ability for instantaneous contextual gestalt-based decision making and high-speed multidimensional simultaneous thinking. This is a radical departure from the sequential logic of older generations. This is a conclusion we can reach after examining the voluminous data available from a new research institute in Japan. The data also indicate that the young adult generation has developed unique strategies of life, which are fascinating but difficult to understand in the framework of our traditional logic but make sense as a transition to the logic of the lower teen generation.     

Marketing versus public relations in selling nuclear power

All too often, the terminology and practices of public relations are used when marketing is what is really needed. This misapplication appears most often when a concept, an idea, or an intangible product is involved. Webster defines public relations as: relations with the general public through publicity; those functions of a corporation, organization, branch of military service, etc., concerned with informing the public of its activities, policies, etc., and attempting to create favorable public opinion.This definition implies a general, ongoing effort to supply information supporting the image of an organization. There is, however, a considerable difference between this kind of activity and the specific, overt process of marketing. This difference has been particularly apparent in attempts of public utilities to “sell” nuclear power plants. Utilities, of course, are monopoly suppliers and, as such, must seek a favorable image in the community. Thus, when public opposition to nuclear power plants mounted, many utilities responded with stepped-up public relations programs; the method they knew best. This article examines the experience of several utilities in locating nuclear plants and suggests how marketing techniques might be used in selling this intangible product.     

'An awkward fence to cross': railway capitalization in Britain in the inter-war years

This paper examines the related problems of the capitalization and financial performance of the railway companies in the inter-war period. It examines the critics' view that the railways were over-capitalized, and places the debate in context by analysing the dividend and accounting policies of the companies and the consequences for investment. It also examines the conflicting views of railway management and shareholders over capital expenditure. The paper concludes that the railways were both financially over-capitalized and physically under-capitalized, and so faced very serious financial problems that were incapable of resolution within the existing ownership structure.     

对当前加强财政监督职能的思考

随着社会主义市场经济的不断发展和完善，对政府部门依法行政的呼声越来越高，财政部门作为国家重要的经济管理部门，其运作的成功与否，关系到国发展和改革的成败，财政监督检查作为国家经济监督体系和国家宏观调控机制的有机组成部分，必须随着经济体制改革的深入和社会主义市场经济的发展而逐步完善并发挥重要作用，本就是在这一思想指导下，对当前如何加强财政监督职能作了一些思考。
