《女神》不仅充满着火山喷发般的激情和粗粝狂暴的格调 ,而且注意意象的营造。《女神》的意象可归纳为神话意象、自然意象、社会意象和文化意象。《女神》的意象创造通常采用变形和变形变意两种方式  相似文献

形式和意义的关联性是分析现代汉语Nl N2同位结构的关键.意义的差异是形式差异得以存在的理由,同位结构的组配关系很大程度上是由意义类别决定的,而所谓的同位不但存在并立性而且还具有一定的修饰关系.人类对客观世界的认识角度会影响到此结构的组配,这种认识来源于社会文化的差异及个人的认知凸现能力.同时N1 N2同位结构和定中结构之间存在一定的纠缠,消除纠缠的方法建立在对结构内部变元成分套累情况的认识上.  相似文献

In this paper we propose a new nonparametric estimator of the conditional distribution function under a semiparametric censorship model. We establish an asymptotic representation of the estimator as a sum of iid random variables, balanced by some kernel weights. This representation is used for obtaining large sample results such as the rate of uniform convergence of the estimator, or its limit distributional law. We prove that the new estimator outperforms the conditional Kaplan–Meier estimator for censored data, in the sense that it exhibits lower asymptotic variance. Illustration through real data analysis is provided.  相似文献

Summary We consider a lotL formed byN apparently similar unitsW 1,…,W N, where each of theW i may come from one of two different populationsP 1 andP 2;T 1,…,T N denote the corresponding lifetimes. The units fromP i undergo a failure of kindi and their survival function isS i (t). We assume that the failure rate function are known and that the units fromP 1 are ?substandard?: λ 1 (t)≥λ 2 (t), ∀t≥0. We want to putW 1,…,W N under a pre-operational test (burn-in test) in order to eliminate at least a great part of the substandard units and we face the problem of obtaining a rule for stopping the test under the assumption that, with the failure of a unit, it is possible to recognize the population from which the unit comes. Such a problem will be formalized as an optimal stopping problem for a suitably defined Markov process. Our study shall evidentiate some fundamental aspects of the problem and the role of the prior distribution of the (random) numberM 0 of those units inL coming fromP 1 (substandard). The latter distribution has a great influence on the form of the solution. This research was supported by the C.N.R. Project ?Statistica Bayesiana e Simulazione in Affidalità e Modellistica Biologica?.  相似文献

Federal legislation regarding health care in the U.S. has increased rapidly in the past few years. A major law with potential far-reaching effects was enacted as a result of increasing legislation and rising health care costs. This law,The National Health Planning and Resources Development Act,has created a network of over 200 local, mostly nongovernment units, called health systems agencies. These agencies are responsible for areawide health planning, plan implementation, review and approval of federal health care expenditures for local programs, and facilities review. They will affect health and mental health programs at the local level. The article is directed to local health and mental health care providers who will, of necessity, deal directly with the local HSA's.  相似文献

根据“一带一路”商事纠纷的显著特征,其解纷机制应满足形式灵活多元、合意性较强、跨国执行便利、专业水平高等需求。仲调结合作为一种复合型纠纷解决方式,与诉讼、商事仲裁、商事调解相比所具有的优势更能满足以上需求。目前,仲调结合主要存在“先调解后仲裁”与“先仲裁后调解”两种实践模式。为了优化仲调结合在“一带一路”商事纠纷解决中的运用,应丰富仲调结合形式与设置具体操作规则,加强仲调结合组织建设与解纷人才培育,充分赋予当事人选择权以克服程序质疑,健全错误仲调结合结果的救济机制,订立多边条约与承认互惠关系以优化跨国执行等。  相似文献

“有X没X”是现代汉语框式结构的一种较为典型的语法构式。当前,学界的研究大多是探究“有X没Y”的句法及语用表现,而对于变项“X”属同一形式的现象尚未涉及。通过外层的形式描写和深层的语义分析,鉴别“有X没X”常规和非常规的用法,指出客观叙述性和主观评价性是区别“有X没X”常规和非常规用法的主要方法。同时,利用句法功能的差异,描绘出现代汉语中“有X没X”所有类型的特点,即“有NP没NP”“有VP没VP”“有一Q没一Q”和“有的没的”4类情况的共性及个性。另外,深入诠释转指性和描述性语义特征的不同是“有X没X”常规和非常规用法区别的关键。  相似文献

Dr. Yellman proposes to define frequency as “a time‐rate of events of a specified type over a particular time interval.” We review why no definition of frequency, including this one, can satisfy both of two conditions: (1) the definition should agree with the ordinary meaning of frequency, such as that less frequent events are less likely to occur than more frequent events, over any particular time interval for which the frequencies of both are defined; and (2) the definition should be applicable not only to exponentially distributed times between (or until) events, but also to some nonexponential (e.g., uniformly distributed) times. We make the simple point that no definition can satisfy (1) and (2) by showing that any definition that determines which of any two uniformly distributed times has the higher “frequency” (or that determines that they have the same “frequency,” if neither is higher) must assign a higher frequency number to the distribution with the lower probability of occurrence over some time intervals. Dr. Yellman's proposed phrase, “time‐rate of events … over a particular time interval” is profoundly ambiguous in such cases, as the instantaneous failure rates vary over an infinitely wide range (e.g., from one to infinity), making it unclear which value is denoted by the phrase “time‐rate of events.”  相似文献

本文基于超总体模型研究抽样调查中设计效应的计算问题。首先以随机效应模型为基础,明确了简单随机、二阶段、不等概率和分层抽样对应的超总体模型,进而通过所给模型推导出分层、类集、加权单因素设计效应的计算公式和多因素组合的设计效应计算公式并给出了对应估计量,公式表明:多因素同时存在的组合设计效应等于对应单因素设计效应的乘积。最后,对设计效应的理论值、估计值和真实值之间的关系进行了蒙特卡洛仿真,并利用相对偏倚、相对均方误进行了评价。本文的研究,对复杂抽样设计中正确计算、使用设计效应具有指导意义。  相似文献

This paper studies the effects of non-normality and autocorrelation on the performances of various individuals control charts for monitoring the process mean and/or variance. The traditional Shewhart X chart and moving range (MR) chart are investigated as well as several types of exponentially weighted moving average (EWMA) charts and combinations of control charts involving these EWMA charts. It is shown that the combination of the X and MR charts will not detect small and moderate parameter shifts as fast as combinations involving the EWMA charts, and that the performana of the X and MR charts is very sensitive to the normality assumption. It is also shown that certain combinations of EWMA charts can be designed to be robust to non-normality and very effective at detecting small and moderate shifts in the process mean and/or variance. Although autocorrelation can have a significant effect on the in-control performances of these combinations of EWMA charts, their relative out-of-control performances under independence are generally maintained for low to moderate levels of autocorrelation.  相似文献
