What’s in a Credo? A Critique of the Academy of Management’s Code of Ethical Conduct and Code of Ethics

The Academy of Management formally adopted a Code of Ethical Conduct in 1990. During the subsequent 15 years, almost nothing had been published about it and its value as a formal document meant to guide professional practice. Rather surprisingly then, in December 2005 an entirely new Code of Ethics was introduced by the Academy’s Board, to take effect in February 2006. Why was a new code promulgated? More broadly, what do the contents of these codes, the processes of their promulgation, and their expressed purposes, suggest about the value of such codes for similarly situated professional associations, in general? This article seeks to identify key strengths and weaknesses of the original code, begin an assessment of the potential value of the new code, and so stimulate debate. Further, not only is this a call to the members of the Academy to engage in some thoughtful debate and possible amendment of its new code, but also a caution to all such associations to take seriously the hurdles that must be jumped before any code can be developed and promulgated to worthwhile effect.

Business Ethics and Accounting Information. An Analysis of the Spanish Code of Best Practice

The main purpose of this article is to analyse one aspect of Spanish business ethics: the role of the transparency and quality of the economic and financial information given to meet the demands and requirements of shareholders. To that end we concentrate firstly on analysing the Spanish capital market and the situation of shareholders prior to the publication in February 1988 of the Code of Best Practice for Spanish Companies, drawn up by a Special Committee created at the request of the Ministry of Economy and Finance. We analyse the importance of the behaviour and actions of three groups which are fundamental to assuring quality and transparency of information: those who prepare financial statements, the Board of Directors (particularly the Audit Committee) and the external auditors. Finally, we look at the possible consequences of the Code of Best Practice on Spanish business ethics.     

浅析建筑企业施工管理费费率的确定

建设工程工程量清单计价规范(GB50500-2008)已于2008-12-01正式实施,规范对清单模式下的投标抱价活动中相关术语做了相应界定,其中将标底正式更正为招标控制价。招标控制价的界定,为招投标活动的合理有效进行铺平了道路。对投标人来说,接踵而来的是投标报价让利问题。如果投标人对自己施工过的项目的管理费用没有具体的量化指标,在施工竟标中将处于劣势。本文站在投标人立场,讨论施工企业管理费率的合理确定问题。

试述用异或算法来实现计算机软件外壳加密的程序

计算机软件产品是一种知识密集的特殊产品,生产一个软件产品需要大量的人力物力,生产难度大,成本高,周期慢。但是,软件产品的复制却是相当的容易。这就导致了非法复制、盗版软件之风的泛滥。加密是目前保护知识产权的一种有效方式。但任何加密软件都可能被破译、我们不能因噎废食。加密与解密,是矛和盾的关系,要想防止被解读,必须提高加密技术。本文利用异或算法对文件的关键代码节来实现了这种加密,防止通过使用Soft-ice或者其他的调试软件来对程序进行反汇编,阻止分析源程序,以此来实现对软件的保护。

SBAS卫星信号的Viterbi译码优化方案

为了减少硬件处理的时间浪费,针对经由卷积编码的SBAS（Satellite-based Augmentatio n System ）卫星信号,提出一种优化的Viterbi译码处理方案。该方案对译码数据流进行截 断处理并进行性能补偿,通过Matlab平台对其进行建模仿真。仿真结果表明,该方案能够在 节约硬件存储容量和减少数据处理压力的同时,获得与传统译码同等的译码性能,这为硬件 实现提供了很好的参考依据。     

宗地统一编码过程中新旧代码无损转换方法

研究目的：通过对宗地统一编码分析,研究旧宗地代码向新宗地代码无损转换的方法。研究方法：理论分析与实例验证相结合。研究结果：（1）宗地统一编码过程中,应使用相同的范围作为城镇地籍调查、村庄地籍调查和农村土地利用现状调查的地籍区和地籍子区的范围;（2）对城镇地籍调查、村庄地籍调查中的调查区与街坊组合代码进行压缩,可实现新旧宗地代码的无损转换;（3）江苏省仪征市的转换实践表明该方法可行。研究结论：所有权宗地与使用权宗地新旧代码无损转换方法具有广泛的应用前景。     

试析媒介融合背景下二维码对广告业的影响

在媒介融合的时代背景下,手机广告作为一种新兴的广告形式日益引起人们广泛关注。相对于传统媒体广告,二维码广告具有受众卷入程度高、传播内容立体化、较强的伴随性和互动性等特点。本文从精确测定广告效果、精准定位消费者、拓宽广告营销渠道、改变广告传播方式等四方面探讨了二维码对广告业的影响,并预测随着互联网的发展、智能手机的普及、3G服务的渗透,手机直接访问互联网将越来越便利,二维码这一新型广告形式将大有作为。
