直觉在哲学中的重要地位合理吗

直觉在哲学中的地位问题,是最近哲学界争论的一个焦点。在哲学分析与论证中,直觉具有十分重要的作用。实验哲学的大量研究发现,直觉具有多样性和差异性。直觉的可靠性因此受到了质疑,直觉的方法论地位因此受到了挑战。“直接论证直觉方法的认知地位”,“否认直觉具有显著的多样性”,“否认直觉多样性的重要性”,“否认直觉的多样性会导致不可靠性”这些策略在不同的程度上捍卫了直觉的方法论地位。正如多变的知觉在认知中具有重要地位一样,直觉的多样性与差异性并不必然动摇直觉在哲学中的地位。     

抗日文学光环掩盖下的文革

何顿的抗日题材长篇小说《来生再见》,其写作的重心不在抗日,而在文革;作家关注的不是历史,而是普通人在极端政治条件下人性的挣扎。生存环境险恶严酷的抗战时期,主人公黄抗日能够应用自己的生存哲学虎口脱身,回到家中安静地生活;但在文革的政治环境下,他却被逼得装疯、吃屎,家破人亡,生活、人格肢解得体无完肤。作品通过这种对比竖起了一座文革无字碑,形成对文革无言的控诉。     

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.     

装置艺术在幼儿园环境创设中的应用探究

装置艺术是现代艺术的一个重要种类,其实质是“场地+材料+情感”的综合展示。幼儿园环境创设中可运用装置艺术,引导幼儿将生活中各种熟悉的材料进行拼贴组合、错置、悬空、分割、集合、叠加,以形成构成环境的装置作品。在此过程中,幼儿是创作环境的本体或参与者,主动参与改造环境,自由地取舍材料以丰富其创造性空间,从艺术陈列的视角对环境进行审美观照,从而提高幼儿的审美修养,激发幼儿的想象力、创造力,美化幼儿园的教学和生活环境,促进幼儿身心发展。     

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.     

模具钢干铣削试验及参数优化研究

为了对铣削力做进一步的研究,以及预测铣削参数的改变对铣削力变化的影响,文章建立了铣削力预测模型,引 入了PSO优化算法。试验采用正交设计方法,干式铣削SKD61模具钢;KISTLER测力仪测量铣削力;HRsoft_DW数采软 件采集试验数据,并对数据进行极差分析。研究结果表明每齿进给量是铣削参数中影响铣削力最为主要的因素。研究 验证了PSO算法对铣削参数优化问题具有有效性。     

"风水"是源自关中的建筑-景观-规划哲学和美学

以"前朱雀,后玄武,左青龙,右白虎"为模式的"风水",实际表示人的住处选址,应当北边靠大山(玄武),南边临水(朱雀),东西由小山岗(青龙,白虎)围合,含有科学道理.从史料和逻辑上看,它应是古代关中周族适应黄土高原地理特点而发展出的一种建筑-景观-规划哲学和美学,包含着中国最早的地理学、景观学、气候学、生态学、建筑学、规划学、心理学等学科的萌芽."风水"模式中后来渗入了迷信成分.现在,我们要继承发扬风水模式中的科学成分,扬弃其中的迷信成分,使之实现现代转型.
