青海汉语方言中的民族语言成分

本讨论了青海汉语方言中的民族语言成分，提供了如何挖掘这些成分的例证，并且从深入研究社会语言学、汉语和普通语言学的需要论述了深入挖掘民族语言成分的重要性。     

喀斯特洞穴探险旅游的审美心理要素分析

旅游审美是旅游者在现实而具体的旅游活动中所进行的一种价值判断活动。与其他的审美活动一样,旅游审美活动也涉及审美心理的四大要素:审美知觉、审美想象、审美理解和审美情感。这四种审美心理要素的深入分析是解构审美活动全过程的关键。对喀斯特洞穴探险而言,其审美活动有其自身的独特性,它不仅能通过刺激游客的视觉和听觉器官来获取美感,而且能最大限度地通过体力和技术的挑战,刺激挑战者的心灵,达到更高层次的愉悦。本文通过对喀斯特洞穴探险旅游审美心理四要素进行分析以及对洞穴探险者的审美体验倾向进行调查,发现在洞穴探险旅游活动中,审美心理的四要素相互作用、彼此融合,产生不同层次的审美体验,洞穴探险者也具有不同的审美体验倾向和需求,对洞穴探险旅游开发具有一定的参考意义。

Components, systems and discontinuities: The case of magnetic recording and playback equipment

Using the history of magnetic recording and playback equipment, this paper explores the relationship between incremental improvements in components and technological discontinuities in systems. It finds that improvements in components have been the major source of all discontinuities in the industry. Focusing just on tape-based systems, all of the basic design approaches had been identified by the late 1950s and thus one of the largest technological challenges for firms has been to modify the design in response to improvements in the magnetic recording density of tape. This paper explores this phenomenon by analyzing data on equipment performance and price, and several design choices for the tape-based equipment. It shows how improvements in the magnetic recording density have changed the tradeoffs that exist between price and different dimensions of performance and between various design choices and thus led to about 10 technological discontinuities in magnetic tape system design.

基于Web服务的网络教学系统的研究

尽管网络教学系统在网上随处可见，但是只有少部分系统能相互共享它们的构件。若开发一个新的网络教学系统，则几乎不能重用已有的构件。因而，要让以不同编程语言在不同平台上开发的构件进行交互是需要耗费很多时间和精力的。本文通过引入Web服务技术，把网络教学系统细分成可重用的构件，使这些构件对外提供的是一种可编程的服务即Web服务，从而解决了传统网络教学系统间构件不能共享的问题。     

C.TEST语言能力的探索性因素分析

本文运用主成分分析法和ML方法对C.TEST进行探索性因素分析。在C.TEST(A—D级)试卷中,提取到了3个公共因素,我们认为C.TEST(A—D级)至少考察到了应试者听的能力、汉字书写能力和图表的识别能力。在C.TEST(E—F级)试卷中,也提取到3个公共因素,我们认为C.TEST(E—F级)至少考察到了应试者听的能力、读的能力和汉语拼音认读能力。这说明C.TEST除了具有较高的信度外,还具有良好的构想效度,即测到了测验设计者想要测到的东西。     

一个带有回收费用和短缺费用的ATO系统

在本文中,我们对Hale,Pyke和Rudi提出的模型进行了改进。他们考虑的是一个有两个产品且每个产品都由两个元件构成,每个产品有一个元件不可替代。低价产品中另一个元件短缺时．可用另一产品中的一个高价元件代替。但是这个模型只考虑了回收费用而不包括短缺费用。本文则建立了一个包括回收费用和短缺费用的新ATO模型,在保证商家收益最大的条件下得到了这四个元件存贮的上下界。     

Diagnosing word decoding problems: A process-analytic approach

In this article we attempt to demonstrate the theoretical and practical limitations of traditional subgroup classifications of acquired and developmental dyslexia. As an alternative, we suggest a process-analytical approach. A variant of a dual-route model for word processing is presented. The model guided the design of a computerized test battery for assessing strategies in word decoding and processes underlying each strategy. The usefulness of the approach was demonstrated on two cases, which according to traditional criteria, were classified as auditory dyslexics. Although both cases displayed marked deficiencies in the phonological route for word decoding, they differed in terms of underlying processes. In one case the primary problem could be located to phonological synthesis, whereas the other case had poor access of letters (phonological recoding). Such individual processing characteristics are not normally revealed by the traditional subgrouping approach.
