日语三段式谜语的“谜面”和“谜底”表面上看来似乎毫无关系,但是通过“共通点”可以发现它们之间存在某种关联。由于谜面和谜底有一定的间距.并不具有最大关联性,同时谜语是人为有意识创作的语言游戏,没有特定的对象,所以要顺利推导出谜底需要借助猜谜者的语境知识。本文拟从认知语用学的角度阐释如何运用认知语境知识推导出合理的、出谜者所期待的谜底。 相似文献

The core issue for the implementation of modern budget law is to optimize the satisfaction of society’s demand for public goods. The form of implementation mechanism that will best achieve this goal has thus become a major topic in the field of legal research. To go beyond the Anglo-Saxon budget model and construct a realistic path for the implementation of China’s budget law, this issue needs to be explored from the perspective of Chinese citizens in a way that safeguards the fundamental interests of the people and is premised on upholding and improving the People’s Congress system, so as to achieve a balance between internal and external budget allocation relationships. There are three routes to implementing China’s budget law: the political, the social, and the judicial. Under the first, citizens’ political identity interests are represented by deputies who oversee the budgetary powers of administrative bodies through the People’s Congress. Under the second, citizens individually or collectively participate, influence or even decide the allocation of public economic resources through dialogue, negotiation, reasoning and argument with the responsible budgetary agency in the course of the budget’s compilation, examination and approval, execution and supervision. Under the third, the establishment of a system for budgetary litigation allows citizens to participate in and supervise the implementation of the budget law, individually or collectively. This provides judicial security for the law’s implementation. These three realistic implementation routes represent the dialectical unity of concerted institutional effort aimed directly at effective implementation of budget law. Judicial interpretations of budget law implementation indicate the importance and urgency of promoting national governance capacity through reform of the legal systems governing finance and taxation. This explains the significant role of finance and taxation law in national governance. 相似文献

Optimality of experimental designs for spatially correlated observations is investigated.come two dimensional correlation structures are discussed and an attempt has been made to find optimal or nearly optimal design for each sitution.The solution lend to designs similar to that used for repeated measurements.The relative efficiency of the proposed designs in comparison to randomized latin square designs is tabulated for some cases. 相似文献

Time series sometimes consist of count data in which the number of events occurring in a given time interval is recorded. Such data are necessarily nonnegative integers, and an assumption of a Poisson or negative binomial distribution is often appropriate. This article sets ups a model in which the level of the process generating the observations changes over time. A recursion analogous to the Kalman filter is used to construct the likelihood function and to make predictions of future observations. Qualitative variables, based on a binomial or multinomial distribution, may be handled in a similar way. The model for count data may be extended to include explanatory variables. This enables nonstochastic slope and seasonal components to be included in the model, as well as permitting intervention analysis. The techniques are illustrated with a number of applications, and an attempt is made to develop a model-selection strategy along the lines of that used for Gaussian structural time series models. The applications include an analysis of the results of international football matches played between England and Scotland and an assessment of the effect of the British seat-belt law on the drivers of light-goods vehicles. 相似文献

Large initial investment in advanced manufacturing systems (AMS) makes it imperative to develop economic justification methods. Once the new system has been properly justified, a critical issue facing the firm is the optimal timing of the installation in an industry. In this paper we use a game-theoretic model by which the optimal timing of the investments in AMSs is analysed. The existence of timing equilibria is demonstrated and simple decision rules of optimal strategy are provided. Economic interpretations of the decision rules are subsequently made clear. Finally, illustrative examples are used to demonstrate the correctness and usefulness of the analysis. 相似文献

Summary. We discuss a Bayesian discovery procedure for multiple-comparison problems. We show that, under a coherent decision theoretic framework, a loss function combining true positive and false positive counts leads to a decision rule that is based on a threshold of the posterior probability of the alternative. Under a semiparametric model for the data, we show that the Bayes rule can be approximated by the optimal discovery procedure, which was recently introduced by Storey. Improving the approximation leads us to a Bayesian discovery procedure, which exploits the multiple shrinkage in clusters that are implied by the assumed non-parametric model. We compare the Bayesian discovery procedure and the optimal discovery procedure estimates in a simple simulation study and in an assessment of differential gene expression based on microarray data from tumour samples. We extend the setting of the optimal discovery procedure by discussing modifications of the loss function that lead to different single-thresholding statistics. Finally, we provide an application of the previous arguments to dependent (spatial) data. 相似文献

运用最优控制理论研究生产性企业组织学习活动的动态最优决策问题.以企业的概念性学习投资率和操作性学习投资率为决策变量,累积知识量、生产率、单位成本和废品率等为状态变量,计划期内的总利润为指标函数,建立了一个最优控制模型,其特点在于规范地描绘概念性学习和操作性学习对企业累积知识量、生产率、单位成本、质量以及企业利润的动态影响.根据生产性企业组织学习和生产经营的实际情况,提出了一些定量化表达的假设和定义.在假设和定义的基础上利用最大值原理分析了所建立的模型,获得了关于动态最优概念性学习投资策略和操作性学习投资策略性质的一些结论,将这些结论与实际问题相结合,指出了在生产性企业组织学习实践上的含义. 相似文献
