对会计信息公开制度的探讨

会计的首要目标是为企业的经营决策提供有用的信息,会计信息公开是适应市场经济发展要求,顺应会计的国际化要求,符合内外部使用者的利益要求,同时也满足企业自身发展的要求的必然,会计信息公开制度的建立和完善是会计发展的趋势,尽管存在着多方面的不足,更多的是需要我们去发现和解决问题,完善和规范我国的会计体系。本文主要从两方面入手：一是确保企业公开的会计信息真实、可靠,前几个途径正是从这点入手的;二是投资者必须能识别和使用会计信息。

Navigation Accuracy Category-Position Models and Estimate Position Uncertainty Calculations for TIS-B System

Navigation accuracy category-position (NACp) is an important parameter for system accuracy of traffic information service-broadcast (TIS-B), which is determined by estimate position uncertainty (EPU). Centered about the problems that the existing EPU calculation based on noise measurement is low in accuracy and unfit for describing uncorrected biases in target reports, this article analyses the traditional NACp model, and uses the least square estimation (LSE) in EPU calculation. Furthermore, it proposes an extended NACp model, which considers both noise and biases and acquires EPU estimation with the help of approximate multiplex Taylor expression. Analysis and simulation show that the proposed method not only leads to significant improvement of the accuracy of EPU calculation, but is fit for EPU calculation with tracking biases in TIS-B system as well. As such it can find application in practice to depict different kinds of error models in TIS-B system.

Dysfunctions of Spatial Cognition in Schizophrenic Patients

ABSTRACT

Twenty outpatients who fulfilled the criteria for a diagnosis of schizophrenia and 28 control participants were invited to learn a route through a complex outdoor environment. They were then tested in tasks intended to explore various aspects of their memorized representation of the navigational episode. Compared to controls, the patients showed significant impairment in both the verbal production of route directions and the drawing of sketch maps. They referred to fewer landmarks and provided fewer directional instructions than the controls, while making a greater number of irrelevant comments. When invited to distinguish between photographs showing views of landmarks encountered along the route and distractors, they performed as well as the controls, and they had similar response times. However, when they were presented with pairs of actual photographs taken along the route, they displayed special difficulty in deciding which of the two landmarks was encountered first along the route. This difficulty in retrieving the sequential structure of the navigational episode suggests that the patients' memories were not accurately linked to one another in their mental representation of the route. These findings are interpreted in the context of current hypotheses about the hippocampal impairment that affects schizophrenic patients.

"装置范式论"的原创性探析

思想家从不同维度对现代技术世界所呈现的世界图景进行了思考。＂装置范式论＂是美国当代著名技术哲学家阿尔伯特.伯格曼（Albert Borgmann）在技术哲学经验转向的背景下,从现象学技术哲学视角对现代技术所引发的超现实现象进行思考的理论成果,这一思想与前人和他人相比,对人类思想史有着原创性贡献。对这一问题的厘清,一方面有助于我国现代化进程中技术政策的选择;另一方面,也有利于人类思想的进一步发展。
