《管子》的“王道”经济观

蕴含《管子》“王道”经济观的主要内容是在粟多国富、兵强战胜的宗旨和目标下,于战备“务具其备”、“盖天下”,以“战胜者地广”为目的,平时的战争动员则坚持视农事为“王之本事”;《管子》“王道”经济观所遵循的最高政治原则是“行义”、“顺于理义”。     

论知识经济时代新型学校管理观

传统的学校管理是一种充满惰性与刚性的管理,它在传统的集权性、计划性和层级性的体制下,在一定的范围内是可行的.进入知识经济时代,社会情境和教育现实变得更加复杂,社会各领域的变迁显得异常频繁,传统的学校管理由于缺乏相应的灵活反应机制,而表现得十分的无能与低效.未来社会时空的切换更为平常与剧烈,高效的学校管理有赖于一个富有创造活力、对情境反应灵敏的柔性机制,从而保证学校同其所处的环境之间以及学校内部知识、信息流通与交换的即时性与顺畅性.学校管理的这些新走向无疑对我们构建知识经济时代的学校管理新观念极具参考与启发价值.     

简析当前我国利用外资的经济安全问题

我们在利用外资的同时,必须注意维护国家经济安全,在当前,我们特别要关注和维护各个产业与金融领域的安全问题。2002年以后外资并购我国企业获得迅猛的发展,而外资并购虽然在某种意义上使我国能获得一定好处,但主要是被外资所利用,让外资捞取了最大利益,而使我国经济受损。因此权衡利弊,从我国实际出发,利用外资一般不宜采取并购模式;今后应严格限制,甚至禁止外资并购、控制我国的龙头企业、关键企业,以维护我国的经济安全。如果把作为国民经济核心和命脉的金融业,特别是四大国有商业银行过多地让外资进入,并逐步扩大其持股比例,对我国金融业以致整个国民经济都不能不说是一个潜在的威胁。我们一定要高举爱国主义旗帜,在继续对外开放的同时,认真维护国家经济安全。

Hadamard matrix methods in identifying differentially expressed genes from microarray experiments

Identifying differentially expressed genes is a basic objective in microarray experiments. Many statistical methods for detecting differentially expressed genes in multiple-slide experiments have been proposed. However, sometimes with limited experimental resources, only a single cDNA array or two Oligonuleotide arrays could be made or only insufficient replicated arrays could be conducted. Many current statistical models cannot be used because of the non-availability of replicated data. Simply using fold changes is also unreliable and inefficient [Chen et al. 1997. Ratio-based decisions and the quantitative analysis of cDNA microarray images. J. Biomed. Optics 2, 364–374; Newton et al. 2001. On differential variability of expression ratios: improving statistical inference about gene expression changes from microarray data. J. Comput. Biol. 8, 37–52; Pan et al. 2002. How many replicates of arrays are required to detect gene expression changes in microarray experiments? a mixture model approach. Genome Biol. 3, research0022.1-0022.10]. We propose a new method. If the log-transformed ratios for the expressed genes as well as unexpressed genes have equal variance, we use a Hadamard matrix to construct a t-test from a single array data. Basically, we test whether each doubtful gene has significantly differential expression compared to the unexpressed genes. We form some new random variables corresponding to the rows of a Hadamard matrix using the algebraic sum of gene expressions. A one-sample t-test is constructed and the p-value is calculated for each doubtful gene based on these random variables. By using any method for multiple testing, adjusted p-values could be obtained from original p-values and significance of doubtful genes can be determined. When the variance of expressed genes differs from the variance of unexpressed genes, we construct a z-statistic based on the result from application of Hadamard matrix and find the confidence interval to retain the null hypothesis. Using the interval, we determine differentially expressed genes. This method is also useful for multiple microarrays, especially when sufficient replicated data are not available for a traditional t-test. We apply our methodology to ApoAI data. The results appear to be promising. They not only confirm the early known differentially expressed genes, but also indicate more genes to be differentially expressed.
