学术期刊属性研究

在编辑传播学界关于学术期刊属性的研究上,普遍存在着一个突出的问题,这就是论者们几乎不假思索地认为“学术期刊是商品”。我们认为,这是一个很大的误区,这种认识在理论上是错误的,在实践上是有害的。首先,“学术期刊商品论”是自相矛盾的;其次,“学术期刊商品论”与马克思主义经济学是相悖的;再次,“学术期刊商品论”与普遍存在的事实是恰恰相反的。学术期刊和学术事业是一项创新的事业,它关系一个国家的生存安危,对此,江泽民同志曾经反复强调,创新是一个民族进步的灵魂,是国家兴旺发达的不竭动力之源。因此,对待学术和学术期刊事业应当像对待军队、警察机构一样,不能也不可能使其商品化,学术期刊应该走自己的健康发展之路。     

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。     

《二十四孝图》新解

《二十四孝图》是中国封建历史上孝子的典范故事,作为华夏民族的优良传统体现出中国独特的人文精神,我们需要为此发扬光大。但需要用马克思历史唯物主义的观点来重新审视这种历史沉淀物,使其更好的体现民族品格。     

电力市场理论的若干基本概念辨析

本文通过对电力市场、电价与电力交易模式等电力经济基础概念的分析,指出了现有概念体系的不足,并提出了作者的认识,尤其是对电力市场一般与市场特殊作出详尽分析,力图为构建竞争性的电力市场经济理论奠定微观概念的基础。     

行政人的伦理困境和伦理自主

行政人与其他人一样生活在复杂的社会关系下并承担着不同的角色,每一种角色都附带着一系列的义务与利益规定。角色冲突、利益冲突甚至是道德冲突产生的伦理困境,使得行政人经常处于两难的境地。因此,应从创设制度化的个人伦理生存空间、行政人对角色责任的清醒认识、弘扬行政人的个体独立人格、界定行政人的忠诚限度等方面帮助行政人找到既可保存公共利益又可保存自己人格完整的有效途径。     

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.     

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。

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.     

Testing symmetry under a skew Laplace model

We develop tests of hypothesis about symmetry based on samples from possibly asymmetric Laplace distributions and present exact and limiting distribution of the test statistics. We postulate that the test statistic derived under the Laplace model is a rational choice as a measure of skewness and can be used in testing symmetry for other, quite general classes of skew distributions. Our results are applied to foreign exchange rates for 15 currencies.
