邓小平的独特机遇观

邓小平独特机遇观是邓小平围绕中华民族几千万海外爱国同胞是中国大发展的独特机遇而提出的一系列理论观点。在邓小平看来 ,几千万海外爱国同胞财力和智力 ,以及他们对祖国的浓厚情感 ,构成中国发展的一种独特的国情 ,而中国社会主义建设对资金和技术的迫切需要 ,又使这种独特国情能够成为一种现实的发展优势。要紧紧抓住这个机遇 ,就必须把几千万海外爱国同胞作为社会主义现代化建设的重要力量来看待 ,制定必要的法律和制度 ,切实保护他们的各种权益 ,从中华民族团结振兴的根本愿望出发 ,吸引他们参加祖国建设。     

植物生长调节物质对矮生一品红不定芽增殖的影响

以几种矮生一品红为材料,研究了植物生长调节剂BA,KT,IAA对不定芽增殖的影响.结果表明,影响一品红芽增殖的主要因素是细胞分裂素,以BA的增殖效果较好.不同品种(自由红、彼德之星、金钱豹、塔巴璐卡)芽增殖所需植物生长调节剂的浓度有所不同,矮生一品红试管苗芽增殖的适宜培养基为MS+BA0.5—2.0mg/L+IAA0.25—0.50mg/L.

The analysis of incomplete data using stochastic covariates

In the development of many diseases there are often associated random variables which continuously reflect the progress of a subject towards the final expression of the disease (failure). At any given time these processes, which we call stochastic covariates, may provide information about the current hazard and the remaining time to failure. Likewise, in situations when the specific times of key prior events are not known, such as the time of onset of an occult tumour or the time of infection with HIV-1, it may be possible to identify a stochastic covariate which reveals, indirectly, when the event of interest occurred. The analysis of carcinogenicity trials which involve occult tumours is usually based on the time of death or sacrifice and an indicator of tumour presence for each animal in the experiment. However, the size of an occult tumour observed at the endpoint represents data concerning tumour development which may convey additional information concerning both the tumour incidence rate and the rate of death to which tumour-bearing animals are subject. We develop a stochastic model for tumour growth and suggest different ways in which the effect of this growth on the hazard of failure might be modelled. Using a combined model for tumour growth and additive competing risks of death, we show that if this tumour size information is used, assumptions concerning tumour lethality, the context of observation or multiple sacrifice times are no longer necessary in order to estimate the tumour incidence rate. Parametric estimation based on the method of maximum likelihood is outlined and is applied to simulated data from the combined model. The results of this limited study confirm that use of the stochastic covariate tumour size results in more precise estimation of the incidence rate for occult tumours.

西部金融发展的路径选择探析

通过我国东、西部金融发展水平的比较，发现西部金融正处于一种迟缓发展状态，因而未能真正发挥出对区域经济的促进作用。经过分析，认为西部应选择供给引导型金融发展道路，主动通过金融先行发展来加速经济增长。     

A Two-dimensional Heat Transfer Model for Atmosphere-land System in the Lake-dominated Alaskan Arctic

1 Introduction Shallow tundra lakes are one of the dominating landscape features in the Alaskan Arctic. They typically cover 20% of the total area of the North Slope of Alaska, and up to about 40% in the coastal plain [1,2]. Many lakes are, in their entirety or in part, shallower than the maximum annual ice thickness, consequently, some ice freezes completely to the lake bottom, nevertheless, large areas of water are deeper than the maximum ice thickness and the ice remains afloat througho…     

FDI对我国经济增长的实证分析

就外商直接投资(FD I)对我国经济增长的影响这一焦点问题,国内学者从定性采用多指标和从定量使用传统的基于普通最小二乘法(O LS)下的计量经济模型两个方面进行了比较详尽的研究。本文在现有文献基础上进行了尝试性创新,使用O LS法进行回归分析时,考虑了数据的平稳性问题,进行了数据的平稳性检验,并运用科克伦-奥克特(C ochrane-O rcutt法)方法纠正了可能存在的虚假回归现象,从而使估计结果更加稳健,结论也更加合理。     

延边地方财政对区域经济增长的影响

在延边地方财政支出结构中,生产性支出的比重相对低,这对区域经济增长会产生短期效果影响。利用区域经济增长与地方财政支出之间因果关系模型实证分析延边地区的结果,证实了这一结论。为了区域经济的稳定增长,延边地区应适当提高生产性支出的比重。
