《成都,今夜请将我遗忘》初在网络亮相登场,引起意想不到的轰动。对这部网络文学作品,本文从结构、语言、主旨三个方面,探查了其成败得失,并对有关的网络文学现象进行了分析。作者认为,该作品有开合有致、驰缓得宜的结构纵深,刚柔相间、沉稳活泼的语言韵味,超越传统、深刻凝重的主旨意义。正是这些原因造就了它的成功。 相似文献

"情",指人的各种感情欲望,是<红楼梦>中揭示得最为深透,表现得最为成功的重要内容.梦因情而生,曹雪芹在书中写了大小数十种梦幻,说到底都是为表现"情"服务的.情切切,情未了.梦是情的派生物,作者对书中人物的梦幻写得细腻、逼真、传神,变化多端,熠熠生辉.所揭示的情更是浓烈、厚重、含蓄、深沉,丰富多采,耐人寻味.情与梦浑然一体,梦与情对表现人物揭示主题可谓双峰对峙,相得益彰. 相似文献

A decomposition technique for quantifying the impacts of changes in product mix and process performance on aggregate process-related indicators is presented. Through application of the technique, the real performance of a process can be quantified. Changes in real performance over time can be monitored to provide useful information for process evaluation and production planning. Two case studies, one related to the aggregate defective rate for an assembly line of an integrated circuit fabrication plant and the other to the aggregate inventory turnover for a tyre distribution company, are presented to illustrate the application of the technique. 相似文献

有的学者把东西方文化之间对话存在障碍的主要原因归结为东西方之间的思想传统的结构性差异。中国人的思想具有互系性和通变的特点,而西方人秉持二元对应的思维传统。结构性差异视角下的话语分析可以在词汇、小句和价值观念三个层面上进行。实例分析验证了结构性差异是真实存在的,可使读者对所选语话材料有更加深刻细致的理解。 相似文献

利用1995-2006年数据,采用时序多指标综合评价法,对中国各地区经济发展水平进行评价研究。结论表明:虽然中国1995-2006年经济增长迅速,但是经济发展水平并未得到显著提高;各地区经济发展不均衡,地域差距较大且有逐年扩大的倾向。 相似文献

This paper developed an exact method of random permutations when testing both interaction and main effects in the two-way
ANOVA model. The method of this paper can be regarded as a much improved model when compared with those of the previous studies
such as Still and White (1981) and ter Braak (1992). We further conducted a simulation experiment in order to check the statistical
performance of the proposed method. The proposed method works relatively well for small sample sizes compare with the existing
methods.

Nowadays, it is popular that the dealer makes profits by selling a kind of discount coupons, which can be used as money to
purchase commodities with total cost less than or equal to the face value of the coupon. We can purchase a coupon at a price
of 0<s≤1 times its face value and the number of potential purchasable coupons is a given integer l. The customer has the option to buy the goods by cash completely or by a discount coupon. However, each piece of goods can
only use one coupon and the coupon used must have enough balance for the goods. The objective is to minimize the total cost
for purchasing all the goods. In this paper, we reduce the problem to a special bin packing model. We consider the online
problems for all 0<s≤1 and 1≤l≤∞. We present optimal online algorithms for all 0<s≤1 when l=∞ and l=1. For 2≤l<∞, we give both a lower bound and an algorithm, and show the algorithm is optimal for l=2.

A new class of Bayesian estimators for a proportion in multistage binomial designs is considered. Priors belong to the beta-J distribution family, which is derived from the Fisher information associated with the design. The transposition of the beta parameters of the Haldane and the uniform priors in fixed binomial experiments into the beta-J distribution yields bias-corrected versions of these priors in multistage designs. We show that the estimator of the posterior mean based on the corrected Haldane prior and the estimator of the posterior mode based on the corrected uniform prior have good frequentist properties. An easy-to-use approximation of the estimator of the posterior mode is provided. The new Bayesian estimators are compared to Whitehead's and the uniformly minimum variance estimators through several multistage designs. Last, the bias of the estimator of the posterior mode is derived for a particular case. 相似文献

Cameron and Heckman (1998) established that a sequential logit model is more sensitive than many other models to the possible biasing influence of unobserved heterogeneity. This article proposes a method which allows researchers to find out how large this potential problem is for their data, their model, and their hypothesis of interest. This is done by proposing a set of scenarios for this unobserved heterogeneity, and showing how to estimate the effects of interest given these scenarios. The set of results from these scenarios give an indication of how sensitive the results are to assumptions regarding unobserved heterogeneity. This sensitivity analysis has been applied to a study of educational attainment in the Netherlands, and it showed that that the finding that the effect of father's education declined over transitions is quite sensitive to the assumptions made about unobserved heterogeneity, but that the finding that the effect of father's education declined over birth cohorts is more robust than is often feared. 相似文献
