A framework for the analysis of firm risk communication

In this paper, we propose a framework for the analysis of risk communication and an index to measure the quality of risk disclosure. Mainstream literature on voluntary disclosure has emphasized that quantity can be used as a sound proxy for quality. We contend that, in the analysis of the disclosure of risks made by public companies, attention has to be paid not only to how much is disclosed but also to what is disclosed and how.We apply the framework to a sample of nonfinancial companies listed in the ordinary market on the Italian Stock Exchange. To verify that the framework and synthetic index are not influenced by the two factors recognized in the literature as the most powerful drivers of disclosure behavior for listed companies, we use an OLS model. The regression shows that the index of disclosure quantity is not influenced either by size or industry. Thus, the synthetic measure can be used to rank the quality of the disclosure of risks.     

Failure Discrimination and Rating of Enterprises by Semi-Definite Programming

We propose a new method forfailure discrimination and rating of enterprises using financialdata compiled from their balance sheets. No particular distributional assumption is made on the underlying data. Our method automatically discriminates and rates many enterprises using mathematical programming methods. We separate multi-dimensional data byhyperplane and hyper-ellipsoid, so that we can interpretthe results of classification from the geometric point of view. Theproblem to be solved here is a linear programming problem orsemi-definite programming problem which can be solved efficiently byinterior point algorithms. Numerical simulations usingreal data show that hyper-ellipsoid separation generates a result which can be used for practical purposes.     

立用PDA组建无线IC卡表抄收系统的设计与实现

本文介绍了应用PDA组建无线IC卡表抄收系统的设计与实现。无线IC卡表抄收系统由PDA、无线转发器、微型打印机、无线IC卡表组成。PDA、无线转发器、微型打印机之间采用蓝牙技术实现通讯连接。使用时，先由PDA发送命令给无线转发器，无线转发器通过内部集成的无线收发模块发出抄表命令给安装在用户家中的无线IC卡表，无线IC卡表对接收的抄表命令做出应答，返回抄表数据并经无线转发器发送给PDA，PDA可以方便地选取用户和浏览数据，通过微型打印机现场打印抄表单，从而可实现免入户抄表，现场批量抄表，现场打印抄表单等诸多功能。     

Deposit interest rates, asset risk and bank failure in Croatia

Financial deregulation, while beneficial in the long-term, seems to be linked to instability. Intense competition for deposits appears to be an ingredient in instability. We examine the aftermath of deregulation in Croatia, which included rapid growth of both deposits and deposit interest rates, followed by numerous bank failures.

Using panel regression techniques, we find evidence of “market-stealing” via high deposit interest rates. We connect high deposit interest rates to bank failure using logit models. High deposit interest rates were a reliable signal of risk-taking. When supervisory capabilities and powers are weak, deposit interest rate regulation may be worth considering.     

中美邀请言语行为对比研究

邀请言语行为是语言中不可缺少的部分,对于日常交际有着一定的影响;邀请言语行为与民族文化有着密切的联系,体现出不同民族的文化特色,遵循着不同的民族礼貌规范;不了解邀请言语行为的规范及其背后的民族文化,就会导致跨文化交际失误;外语教学中培养学生得体的邀请言语行为能力,可以帮助他们减少语用失误。     

采用分割频带法构造宽间隔跳频序列

为增强对偶频带法的保密性,提出了融入随机特性的宽间隔处理新方法——分割频带法。首先对给定的频带进行均匀划分,分割后各区间频带频点相互对应,然后按照随机跳变优先原则或平均间隔优先原则构造区间频带表,以控制跳变规律,实现各频带间的随机转换。分割频带法继承了对偶频带法的核心思想,不改变原始序列的周期长度。理论分析和Matlab仿真结果表明,分割频带法构造的宽间隔序列性能优越,在不恶化序列汉明相关性的前提下,提升了序列保密性和平衡性,可作为宽间隔处理的有效方法。

论协理：社会资源配置的第三机制——当代和谐社会的基本建构机制

由于市场机制与行政权力机制分别存在着失灵现象,第三种社会资源配置机制应运而生,这就是“协理”机制。其核心是无政府而有管理,无市场而达自治与协调,社会关系网络是其基本存在形态,伦理原则是其力量基础,而既非国家产权也非私人产权的“人际产权”是其适用领域。今天它已经成为克服市场机制与政府机制的缺点、建设和谐社会的基本社会机制。     

跨文化交际能力培养在大学英语教学中的应用分析

该文从跨文化交际的定义人手,分析了我国大学英语教学中有关学生文化素养方面的现状与问题,探寻了跨文化交际能力培养在大学英语教学中的必要性与可行性,并对具体的策略及原则进行了探讨与建议。认为应当同时对高校英语教师与大学生进行相关的文化素养的训练与输入,从而提高大学英语习得者的学习效果和跨文化交际能力。
