甲骨文象形码编码方法研究

甲骨文因字形独特、年代久远,所以一直没能进行有效编码。本文吸取现代编码思想,采用模糊数学模型分析甲骨文的部件(字根)特点,对其进行模糊聚类,并使用32个字符(25个英文字母和7个阿拉伯数字)作为码元,与甲骨文中的500多个字根相对应,实现了一字一码的编码方案。在此基础上,运用信息论中的熵理论,分析了这种编码的效率和科学性,得出甲骨文编码的最佳码长大致接近于3,从而为5000多个甲骨文字进行科学编码提供理论基础。

Perception of difficulties for the back related to asssembly work: general findings and impact of back health

The study objective was to describe the perceptions of airplane assemblers on job demand for the back and how back pain modulated these perceptions. One hundred and seventy-six workers answered two questionnaires concerning back pain and the perception of work related difficulties (work activities, work contexts, tools, work positions, efforts). Results show that positions and work contexts are perceived as greater sources of difficulty than efforts or dynamic activities. The duration of a given position is more important than its frequency. Back pain has a significant but complex impact on the perception of difficulty. Assemblers appear to integrate several factors when evaluating their difficulties as opposed to individual aspects, as it is often measured in ergonomic studies. The results have important implications for the measurement of ergonomic factors in the genesis of back pain and illustrates the potential for misclassification and biases in current epidemiologic studies.

遗传神经网混合编码方式的研究

对遗传神经网中符号编码方式造成的初始种群分布不均的缺点以及二进制编码方式包含的节点信息不完全的不足进行了分析，并综合二者利弊提出了一种改进的以二进制编码方式为基础的混合编码方式，同时针对这种混合编码方式设计了一套专门的遗传操作算子，克服了两种单一编码方式的缺点，有效地提高了遗传神经网的收敛速度。利用所提出的方法对传统的5-bit Parity基准问题以及沙尘暴天气预测的实际问题进行了仿真计算，比较了编码方式改变前后的收敛速度及分类准确性，仿真结果验证了这种改进的有效性。     

A taxonomy of novice user perception of error on the Web

Novice users face many challenges when browsing the Web. The goal of this experiment was to learn about how users perceive error situations when using the World Wide Web. Specifically, the goal was to learn which circumstances cause users to believe that an error has occurred. An exploratory experiment took place with 78 subjects who were novice users. In the experiment the subjects were asked to identify when they perceived that an error had occurred. The subjects reported a total of 219 error situations. These error situations were then classified by the researchers into the following four categories: user error, system error, situational error, and poor Web design. Based on the collected data, suggestions are presented for improving the usability of Web browsers and Web sites.     

概念化心智活动的关键地位与交流的实现

语言符号并非天然地和它所指的客观事物或现象直接而精确地对应。人脑或心智活动的产物，即思想或概念，是将语言符号与客观事物或现象联系起来必不可少的媒介，这是Ogden和Richards名的语义三角理论的灵魂。由此可以认为，外界事物引起人脑主观思维活动并将其结果外化出来，这实质上是概念化问题。简要讨论了这种概念化过程的关键地位及其复杂性。

Objectivity in the Eye of the Beholder: Divergent Perceptions of Bias in Self Versus Others.

Important asymmetries between self-perception and social perception arise from the simple fact that other people's actions, judgments, and priorities sometimes differ from one's own. This leads people not only to make more dispositional inferences about others than about themselves (E. E. Jones & R. E. Nisbett, 1972) but also to see others as more susceptible to a host of cognitive and motivational biases. Although this blind spot regarding one's own biases may serve familiar self-enhancement motives, it is also a product of the phenomenological stance of naive realism. It is exacerbated, furthermore, by people's tendency to attach greater credence to their own introspections about potential influences on judgment and behavior than they attach to similar introspections by others. The authors review evidence, new and old, of this asymmetry and its underlying causes and discuss its relation to other psychological phenomena and to interpersonal and intergroup conflict.

The Octave Illusion Revisited Again.

The octave illusion (D. Deutsch, 1974) occurs when 2 tones separated by an octave are alternated repeatedly, such that when the right ear receives the high tone, the left ear receives the low tone, and vice versa. Most subjects in the original study reported hearing a single tone that alternated from ear to ear, whose pitch also alternated from octave to octave, and D. Deutsch (1975a) proposed an explanation in terms of separate what and where auditory pathways. C. D. Chambers, J. B. Mattingley, and S. A. Moss (2002) argued that the perceived pitch difference generally corresponds more to a semitone and proposed an alternative explanation in terms of diplacusis. This article argues that Chambers et al. used problematic procedures and reports a new experiment on the octave illusion. The findings confirm that an octave difference is generally perceived, and they agree with the model of Deutsch (1975a) but are at variance with the diplacusis hypothesis.
