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

The authors extend the block external bootstrap to partially linear regression models with strongly mixing, nonstationary error terms. In addition to providing an approximate distribution for the semiparametric least square estimator of the parametric component, they propose a consistent estimator of the co‐variance matrix of this estimator. 相似文献

Oja (1983) examined various ways of measuring location, scatter, skewness, and kurtosis for multivariate distributions. Among other measures of location, he introduced a generalised median known in this paper under the name of the Oja median. In our study of the existence of that median, we show that Oja's definition can only be applied to distributions having a mean. In dimension d θ 2, we establish that the usual method of extension breaks down, which raises the question of the validity of the concept as a notion of median. Two fundamental theoretical properties of that median are also considered: uniqueness and consistency. 相似文献

This paper develops a model ofinter vivos gifts and bequests in a setting of moral hazard and adverse selection. Altruistic parents do not perfectly know how much effort their children make to earn their living, nor do they know their true level of ability.Inter vivos gifts take place prior to the realization of the children's earnings whereas at the moment of bequests, parents do observe them. We show that an optimal transfer policy generally uses a mix ofinter vivos gifts — deemed as more efficient — and bequests — deemed as more redistributive.We are thankful to Allessandro Cigno, Jacques Cremer, Claude d Aspremont and anonymous referees for their comments.Responsible editor: Alessandro Cigno 相似文献

Network analysis, a methodology derived from general systems' theory, can be utilized as a community mental health administrative-evaluation procedure. Evaluation parameters derived from analysis of patient data as they “flow” through a network of agency services, provide measures of systemic functioning. These parameters include “longest paths” and various ratio relationships as evaluation measures of service delivery. The limitations of network analysis are examined by means of conceptual analyses, and phenomena that emerged from research experience. The necessity for both quantitative and qualitative data to ensure a meaningful evaluation of mental health services is explained. Conclusions about the value of the network analysis approach are considered. 相似文献

Many government agencies have "constituents" who believe the agencies should hear and consider their needs and desires in establishing program priorities. This article describes how one involves interested constituents (consumers, industry, medical professionals, and state organizations) in the agency's annual priority-setting process. This participation has produced a number of beneficial results-some expected and some unexpected. 相似文献

随着当前我国奢侈品消费人数的不断攀升及奢侈品消费金额的不断提高,中国的奢侈品消费从整体上看未富先奢的局面已经出现。其大致可分为两类:一类是传统奢侈品的消费,消费人群主要集中在超富裕阶层;另一类是新奢侈品的消费,消费人群是中产阶级和白领。从影响我国消费者奢侈品消费的主要动机来看,人际性消费是影响我国奢侈品消费的主要动机,其中符号性消费是影响我国当前奢侈品消费的首要因素。符号性消费、从众性消费与人情消费都属于非理性的消费行为,促使我国奢侈品消费呈现出一种非理性状态。因此.应大力倡导理性消费.同时也要抓住契机。加大宣传营销力度与创新.树立自己的民族奢侈品牌,更好地发施我国经济 相似文献

Using Monte Carlo methods, the properties of systemwise generalisations of the Breusch-Godfrey test for autocorrelated errors are studied in situations when the error terms follow either normal or non-normal distributions, and when these errors follow either AR(1) or MA(1) processes. Edgerton and Shukur (1999) studied the properties of the test using normally distributed error terms and when these errors follow an AR(1) process. When the errors follow a non-normal distribution, the performances of the tests deteriorate especially when the tails are very heavy. The performances of the tests become better (as in the case when the errors are generated by the normal distribution) when the errors are less heavy tailed. 相似文献
