经济分配中公平因素的心理学研究现状评述
A Review on Research of Fairness Concerns in Economic Distribution
 [PDF]


Advances in Psychology (AP) , 2015, DOI: 10.12677/AP.2015.54030
Abstract:
经济学中的经典的理性人假设认为,人都希望以尽可能少的付出,获得最大限度的收获。然而行为经济学中经典的最后通牒博弈、独裁者博弈等实验的结果显示了人们在经济分配中不一定都服从理性人假设,作出了非“理性”的选择,他们似乎厌恶不公平的分配,甚至宁愿牺牲自己的利益惩罚不公平的行为。本文主要介绍了行为实验和神经科学实验中使用的最后通牒博弈、独裁者博弈及其主要结果。
The hypothesis of rational economic man in classical economics assumes that people always want to maximize their gains and minimize their losses. However, the behavioral results of classical paradigms in behavioral economics like Ultimatum Game and Dictator Game have suggested that people's behaviors in economic distribution are not in line with the rational assumption, and they are likely to make irrational choices. People tend to avoid unfairness in distribution, and even pu-nish unfairness proposers at the cost of their benefits. The present paper reviews the use of Ulti-matum Game and Dictator Game in the psychology and neuroscience studies and relevant results.

地震动非平稳特性对结构非线性响应影响的分析
,林学
工程力学 , 2006,
Abstract: 虽然地震动的非平稳特性被越来越多的研究者所认识,但是其对结构非线性响应的影响却一直没有较为深入的研究。传统的反应谱和功率谱缺乏对地震动时间信息的表达,而由小波变换得到的地震动局部谱(时变谱)能更准确地反应地震动的非平稳性。更为重要的是,小波变换可以将地震动能量在时间上的分布进行调整而不改变能量在频率上的分布,对考察地震动非平稳性对结构非线性响应的影响非常有利。利用小波变换的上述优势,对比分析了三条实际地震动记录对一榀钢筋混凝土框架非线性时程响应的影响,通过调整其中一条记录的能量在时间上的分布,清楚地表明地震动能量在时间上的集中对结构响应非常不利,并由此提出了有效峰值的概念来定量反应这种表现为能量集中的地震动非平稳性。
目标设置对工作记忆成绩影响的实验研究
,
心理科学 , 2011,
Abstract: 为了回应locke提出的“目标设置理论仍然需要发展”的观点,本文从认知心理学的角度对目标设置理论进行了检验。结果表明设置明确且有一定难度的目标比设置模糊或一般性目标会使被试产生更高水平的努力,从而提高成绩;设置明确但难度偏低的目标与设置模糊目标的成绩间并无显著性差异;被试对目标的可接受性程度越高,成绩越好;任务难度变量对目标难度与成绩之间的调节效应要通过被试对策略的发掘和使用以及在时间方面给予一定的压力才能得到体现。

Abstract: 针对JPEG2000中的5/3小波和9/7小波存在的高存储问题,通过改进离散小波变换(DWT)的提升算法,提出了一种统一的高性能、低存储的2维离散小波变换架构。采用该算法实现的2维离散小波变换架构不仅省去了行列模块间的转置缓存,而且减小了片内缓存的大小。对于N×N大小的图像(N为图像宽度)进行5/32维DWT仅需要2N大小的片内缓存,进行9/72维DWT仅需要4N大小的片内缓存,而且通过采用流水线技术还可将关键路径缩短为一个乘法器的延时。和已有的2维DWT架构相比,该统一架构具有更低的片内存储器需求和更高的性能。该架构经VerilogHDL描述,并在ModelSim中验证正确。在AlteraStratixⅡFPGAEP2S60F1024C4中综合的结果显示,对于1024×1024大小的图像,需要1284个ALUT,片内存储器的大小为4K,最高频率可达172.56MHz。

Abstract: 摘要 在现有水印隐藏容量模型研究的基础上,提出了MPEG声心理学模型1掩蔽门限限制下的语音信息隐藏容量和一种能够达到该理论容限的秘密信息编码方法.同时也计算出当采样率为44.1 kHz的载体语音概率密度函数满足高斯正态分布时,其在MPEG声心理学模型1掩蔽门限限制下的隐藏容量为2787 bit/s.
The article presented a data capacity estimation method for speech information hiding. It uses human auditory system (HAS) model to estimate the data hiding capacity of speech, or the maximum number of bits that can be embedded in speech. MPEG HAS model 1 was modified to estimate the just noticeable difference (JND) for FFT and power spectrum density coefficients. At the same time, a new embedded method that can reach the data capacity was introduced. The maximum number of bits was also calculated that can be embedded in speech to 2 787 bit/s when embedded speech is white noise.

Abstract:
本文采用一种简单的高温溶剂方法合成了新颖的凸多面体状AgCl半导体纳米材料。通过X射线衍射仪,扫描电子显微镜,漫反射光谱和紫外–可见分光光度计对材料的微观结构和光催化性能进行了表征。结果显示,所得到的凸多面体氯化银纳米材料在可见光区间显示了非常好的吸收,并在降解罗丹明B染料的过程中显示出高效的光催化活性。此外,我们对所制得的AgCl凸多面体的光催化稳定性也进行了探讨。
Novel convex polyhedra-like AgCl nanoarchitectures were synthesized via a facile refluxing method in the polyoldiethylene glycol (DEG). The microstructure and photocatalytic properties of the prepared materials were characterized by X-ray diffraction, scanning electron microscope, diffuse reflectance spectroscopy and UV-visible spectrophotometry. Results show that the as-obtained AgCl nano-polyhedra could effectively increase the absorption of the photocatalysts from UV-light to visible light and show an obvious efficient photocatalytic activity for degradation of RhB dye. Besides, the stability of the product in organic dye photodegradation process was also investigated.
棉结在静电场中的运动规律

纺织学报 , 2013,
Abstract: 研究了棉结在静电场中运动规律的问题。采用自制静电装置,将静态下的纤维棉结和带籽屑棉结放置在静电场中,通过调节静电压来观察纤维棉结和带籽屑棉结在静电场中的充电和起飞情况。实验得出了不同类型的棉结在静电场中脱离极板的电压范围,总体来说同类材料中取出的带籽屑棉结脱离极板的平均场强要高于纤维棉结的平均场强。通过相关性分析得出棉结在静电场中起飞所需场强与样品的aQura棉结平均直径检测结果呈正的直线相关。上述结论为静电型棉网清洁器在梳棉机上的应用奠定了理论基础。
