黑龙江省工业资本产出贡献率的实证分析

提高老工业基地的经济增长水平,是一个意义深远的课题。黑龙江省老工业基地发展相对落后的原因在于工业实收资本结构的不合理,国家资本偏高,个人资本绝对性偏低,单位个人资本效率是单位国家资本的五倍。法人资本的多层代理也是造成黑龙江省工业发展相对落后的原因之一。对此,应妥善解决委托代理失灵问题,大力促进民营资本的发展,加快国有经济布局的战略性调整。     

进化的精神和生活的道德——鲁迅与契诃夫人生哲学比较论

面对着现实困境的鲁迅与契诃夫都珍视人生的价值,强调人的自我意识与主体力量,但是由于文化传统与历史背景的不同,他们的人生哲学各具特色。鲁迅的人生哲学体现了战斗的进化精神,契诃夫的人生哲学探讨了超脱的生活道德。     

基于可达性的用户最优动态交通配流模型研究

以多种已有模型为基础，建立了动态配流流量细化原则，并依据这一原则，在避免估算路段走行时间的情况下构造了一个改进的新模型．该模型的解释性强，具有全局收敛性，并考虑了距离不同带来的可达性的影响．在对该模型最优解条件的充要性进行说明的同时，对新模型的择路机理也予以了推证．     

Towards Enhancement of the Economy of a Thermal Power Generating System through Prediction of Plant Efficiency

The plant ‘Heat Rate’ (HR) is a measure of overall efficiency of a thermal power generating system. It depends on a large number of factors, some of which are non-measurable, while data relating to others are seldom available and recorded. However, coal quality (expressed in terms of ‘effective heat value’ (EHV) as kcal/kg) transpires to be one of the important factors that influences HR values and data on EHV are available in any thermal power generating system. In the present work, we propose a prediction interval of the HR values on the basis of only EHV, keeping in mind that coal quality is one of the important (but not the only) factors that have a pronounced effect on the combustion process and hence on HR. The underlying theory borrows the idea of providing simultaneous confidence interval (SCI) to the coefficients of a p-th p(≥1) order autoregressive model (AR(p)). The theory has been substantiated with the help of real life data from a power utility (after suitable base and scale transformation of the data to maintain the confidentiality of the classified document). Scope for formulating strategies to enhance the economy of a thermal power generating system has also been explored.     

波普尔证伪主义方法论与决策科学

科学方法论对科学活动的研究,目的在于探索科学发现和科学检验所遵循的基本规则,并为科学预测和科学决策提供合理的依据。我国关于科学方法论的研究,主要集中在科学发现和科学检验这两个阶段,而对科学方法论的应用阶段———科学预测和科学决策———的研究则较为薄弱。本文通过波普尔证伪主义方法论与决策科学的比较,认为无论在决策科学的基础理论方面还是在决策科学的方法上,证伪主义方法论对决策科学都产生了重要的影响。     

关于学报发展中几个问题的思考

在互联网日益普及的情况下，高校学报不应等待观望，而应尽快转变认识，充分利用网络资源进行新的尝试，为自身的发展服务。高校学报要走的个性化特色化之路，通过对可资形成特色的各种条件进行创造性整合，形成刊物的个性与特色。注重提高刊物的学术影响力，提高所刊论文的引用率与引文率，在增强社会效益上做文章。同时，也要重视编排的标准化、规范化等工作，以期使学报的生存与发展进入良性循环。     

论新文学思潮与新文学流派的动态关系

新文学思潮与新文学流派之间因果莫辨、源流纠缠的动态关系 ,充分证明了近百年来新文学思潮与新文学流派本身非线性、非对称的生存状态。所谓非线性与非对称 ,其实质就是不稳定性和不成熟性 ,它们直接制约着新文学近百年发展进程 ,使之在历时态和共时态上始终呈现出某种程度的不良生存状态和发展趋势。     

谈批判性思维

批判性思维与创造性思维是两个相对独立又相互联系的思维方式。解决问题的过程实质上是对两种思维方式的综合运用。因此在教学改革中应该把对两者的培养和训练结合起来,使学生在总体思维能力上得到提高。     

A simple procedure for the selection of significant effects

Summary.  Given a large number of test statistics, a small proportion of which represent departures from the relevant null hypothesis, a simple rule is given for choosing those statistics that are indicative of departure. It is based on fitting by moments a mixture model to the set of test statistics and then deriving an estimated likelihood ratio. Simulation suggests that the procedure has good properties when the departure from an overall null hypothesis is not too small.     

Statistical Analyses and Modelling of the Mixing Process of Euro Coins in Germany and Europe

This paper reports on the mixing of Euro coins from different countries of origin in Europe, which started on 1 January 2002. There is an interesting conclusion: that the mobility of small and large denominations is different. The long‐term behaviour of the mixing process is studied using a simple deterministic model and data from Germany, France and the Netherlands. The analysis leads to predictions about the future progress of the mixing process.
