构建高校知识产权保护体系

高等学校在从事科学研究和技术开发的过程中,形成了面向经济建设需要的人才队伍培养和科技基地建设的局面,由此产生了对原始创新成果和知识产权的保护不足,直接导致了高校知识资本流失,影响到高校科技原始创新的积极性和科技水平.为此,高等学校应该以自己为主体,以企业为支撑,以市场为舞台,构建富有特色的高校知识产权保护战略实施体系.     

展现多元态势 透视艺术魅力--解读《新世代小说大系-爱情卷》

二十世纪八九十年代是台湾社会政治、经济、文化向多元化转型的时期,爱情小说在此时更是以"新世代"的姿态蓬勃地发展起来,呈现出生机勃勃的多元化态势.从形式的创新、意象的重塑、情感的试验诸方面展示了现代爱情小说的艺术魅力.     

国有中小企业民营化及其模式探索

我国国有中小企业制度变革正处于"卡尔多改进"阶段,主要表现为发展模式的分化。民营化是近几年人们热衷于理论和实践的一种模式。我们认为,国企民营化与国企民有化是两种不同性质的制度安排,前者是指企业在国有基础上的民间经营方式,是所有制的实现形式;后者是指企业的国有产权转变成民有,是所有制的彻底变革。目前,我国国有中小企业民营化的条件是比较充分的。通过比较论证,托管制是一种较为可行的模式之一。     

论诗绝句与文学批评

论诗绝句作为一种特殊形式的文学批评体裁,言简意精、凝练含蓄.比起抽象的说理来,给人的印象更为深刻而具体.它能把复杂的含义浓缩在极小的篇幅之中,这就是论诗绝句在文学批评作用上所恃有的最大长处.自唐代以后,历代文人递而祖述,绵延至今,使论诗绝句已成为我国古代文学理论批评的重要形式之一.     

壮族《嘹歌》的传承与传播研究--壮族《嘹歌》文化研究之七

《嘹歌》的源头至少可以追溯到《麽经布洛陀》记载的“嘹三妹造友”(即造爱情)的歌以及汉代《说苑》记载的《越人歌》、晋代《交州记》记载壮族先民的“辽辽之歌”。这里的“嘹”、“辽”是壮语“玩乐”之意,是汉字记壮音。《嘹歌》传承与传播的媒介有家庭、歌圩、歌书以及现代的广播、电视、录音磁带、VCD光盘等。在现代传媒介入之前,是有文字传承传播与无文字传承传播相结合;之后则是无文字传承传播、有文字传承传播与现代大众传媒传承传播相结合。政府、社会团体在《嘹歌》传承传播中起到了重要作用。     

Likelihood estimation of missing cell means in the fixed model analysis of variance

This paper examines the formation of maximum likelihood estimates of cell means in analysis of variance problems for cells with missing observations. Methods of estimating the means for missing cells has a long history which includes iterative maximum likelihood techniques, approximation techniques and ad hoc techniques. The use of the EM algorithm to form maximum likelihood estimates has resolved most of the issues associated with this problem. Implementation of the EM algorithm entails specification of a reduced model. As demonstrated in this paper, when there are several missing cells, it is possible to specify a reduced model that results in an unidentifiable likelihood. The EM algorithm in this case does not converge, although the slow divergence may often be mistaken by the unwary as convergence. This paper presents a simple matrix method of determining whether or not the reduced model results in an identifiable likelihood, and consequently in an EM algorithm that converges. We also show the EM algorithm in this case to be equivalent to a method which yields a closed form solution.     

Best quadratic and positive semidefinite unbiased estimation of the variance matrix of the multivariate normal distribution

A BQPUE (best quadratic and positive semidefinite unbiased estimator) of the matrix V for the distribution vec X^′∽N_np(vec M^′, U?V) is being given. It is unique, although still depending on U and M. When U = I and M = (μ,…,μ), we get a well-known (unique) result not depending on M.     

Estimation of rational transfer function models

In the estimation of rational transfer function models, it has been recommended that starting values of a transfer function component be assumed to be zero (or a constant) in the recursive computation of the transfer function response. It is demonstrated that such algorithms may lead to serious bias in the estimation of moving average parameters. This paper discusses several other algorithms that may rectify this problem. It is found that the starting-value-free (SVF) method is a more reliable algorithm. For computer programs using the traditional algorithm, i.e., the zero-starting-value (ZSV) method, the bias problem can be easily remedied using a short-cut method that omits appropriate number of values at the beginning of the residual series.
