Symmetrical Design of Experiment in Global Sensitivity Analysis Based on ANOVA High-dimensional Model Representation

This article reviews symmetrical global sensitivity analysis based on the analysis of variance of high-dimensional model representation. To overcome the computational difficulties and explore the use of symmetrical design of experiment (SDOE), two methods are presented. If the form of the objective function f is known, we use SDOE to estimate the symmetrical global sensitivity indices instead of Monte Carlo or quasi-Monte Carlo simulation. Otherwise, we use the observed values of the experiment to do symmetrical global sensitivity analysis. These methods are easy to implement and can reduce the computational cost. An example is given by symmetrical design of experiment.     

Understanding Estimators of Treatment Effects in Regression Discontinuity Designs

In this paper, we propose two new estimators of treatment effects in regression discontinuity designs. These estimators can aid understanding of the existing estimators such as the local polynomial estimator and the partially linear estimator. The first estimator is the partially polynomial estimator which extends the partially linear estimator by further incorporating derivative differences of the conditional mean of the outcome on the two sides of the discontinuity point. This estimator is related to the local polynomial estimator by a relocalization effect. Unlike the partially linear estimator, this estimator can achieve the optimal rate of convergence even under broader regularity conditions. The second estimator is an instrumental variable estimator in the fuzzy design. This estimator will reduce to the local polynomial estimator if higher order endogeneities are neglected. We study the asymptotic properties of these two estimators and conduct simulation studies to confirm the theoretical analysis.     

Indirect membership function assignment based on ordinal regression

In many fuzzy sets applications, fuzzy membership functions are commonly developed based on empirical or expert knowledge. The equation of a membership function is usually determined somewhat arbitrarily. This paper explores a novel membership function design method based on ordinal regression analysis. The estimated thresholds between ordinal measurement categories are applied to calculate the intersection points between fuzzy sets. These intersection points are further applied to determine the equations of the membership functions. Information distortion due to empirical guess can thus be reduced and more latent information in the fuzzy responses can therefore be captured. A case study investigating the relationship between foster mothers’ satisfaction and the foster time and information provided has been conducted in this research. The applicability and effectiveness of the proposed membership function assignment approach have been demonstrated through several case studies.     

以目的与背景知识为双条件的逻辑AKC

首先,我们构造以目的和背景知识为双条件的条件句系统AKC,给出它的一些证明论结果。其次,我们引入有序邻域语义,给出描述AKC的特征公理和推理规则的框架条件,证明AKC相对这些框架条件是框架可靠的。最后,我们证明AKC相对这些框架条件也是框架完全的。     

新形势下促进农民增收的政策选择

论港口产业规制契约的重新设计

20世纪70年代以后,在世界范围内出现港口产业规制改革浪潮,竞争机制和私人部门被更多地引入。那么在港口产业规制的新框架下,有必要对规制契约进行重新设计,以满足港口规制实践的需要。对包括价格上限规制、投资规制等在内的港口产业规制契约的核心内容进行了说明,并探讨了契约重新设计中若干关键要素的确定。     

工业设计的多元功能及其对河南开放带动战略的影响

全面、准确地认识工业设计的多元功能是发展和利用工业设计的前提。工业设计与产品直接相关的功能称为工业设计的直接功能或微观功能,工业设计通过产品表现出来的对经济运行全局发生作用或影响的功能叫间接功能或宏观功能。工业设计的多元功能对河南开放带动经济战略的实施,有重要的推动作用。     

中国传统纹饰与现代设计

面对中国的设计现状,我们应该倡导民族文化和先进文化,使中国的传统文化艺术在现代设计中得以延伸发展,打造新的民族形式,在理解的基础上取其“形”、延其“意”、从而传其“神”,用中国传统文化精粹,以现代化国际化语言来表达,使民族的文化精神和世界的设计语言,共同融汇成现代设计艺术的主流,必定会使现代设计更具文化性与社会性。     

对现代期刊封面装帧设计的再认识

改革开放以后,期刊封面装帧设计在“全球一体化”的趋势下,正以崭新的面貌呈现在国内外读者面前,在人文性、个性化、时尚性、市场性等方面突显出与时代同步的特征。如何与时俱进的创造出具有本民族特色的期刊装帧设计风格,将是值得深思的问题。     

论色彩设计的回归

现代设计之后的设计思想与实践不仅从环保的、生态的角度积极探讨研究通过设计建立新型的人与自然的和谐共生关系,而且尊重不同的文化,弘扬人文主义精神,并且取得了许多成就。但色彩设计作为现代设计中的重要因素,从设计理论研究和实践应用两方面都还存在不足。文章立足于色彩和色彩设计的本质属性,对色彩和色彩设计的概念、现象及应用进行反思和再认识,主张色彩设计应回归自然本质和人文精神的体现,并在色彩设计中建立系统观念,更好地对色彩设计进行定位。这样才能满足现代设计发展的需要,发挥色彩设计更大的作用。
