基于报表项的合并报表系统架构设计

大型企业集团由于合并范围广、股权结构复杂、关联交易频繁等特点,其合并报表工作难度较高,为了提高编制效率和质量,许多企业开始使用信息化工具完成合并报表的编制。本文分享了一种基于报表项的合并报表系统架构设计,对报表项的内容、编制方法和优缺点进行了解析,并从系统的设计思路和数据收集审核、合并模型配置、抵消处理、合并处理、报表输出功能模块探讨合并报表系统架构的设计。这种通过报表项收集数据和处理合并过程的方式在报表体系没有重大变化的情况下,增减部分报表项对系统逻辑影响很小,且合并过程可以跟踪展现,具有一定的借鉴意义。

浅谈会计电算化系统的内部控制

一、会计电算化中存在的一些问题 1.电子数据的审核和确认. 计算机具有强大的运算功能,从输入信息到输出财务报告的全过程,完全由计算机自动完成.电子原始数据经审核和确认后,就可自动生成电子记账凭证,而由这些记账凭证直接生成的账簿和报表都是派生性的数据.所以,账簿和报表的正确性、真实性完全取决于审核和确认的电子数据.在电算化环境下,直接更改记录在电脑磁盘或光盘上的电子数据,从而通过计算机舞弊和犯罪的可能性更大,更难以被发觉.     

Motivation and sorting of human capital in open innovation

This paper studies how business models can be designed to tap effectively into open innovation labor markets with heterogeneously motivated workers. Using data on open source software, we show that motivations are diverse, and demonstrate how managers can strategically influence the flow of code contributions and their impact on project performance. Unlike previous literature using survey data, we exploit the observed pattern of project membership and code contributions—the “revealed preference” of developers—to infer the motivations driving their decision to contribute. Developers strongly sort along key dimensions of the business model chosen by project managers, especially the degree of openness of the project license. The results indicate an important role for intrinsic motivation, reputation, and labor market signaling, and a more limited role for reciprocity. Copyright © 2014 John Wiley & Sons, Ltd.     

湿球温度计算方法研究

电力设计中冷却塔的设计经常需要用到湿球温度这一参数,但是气象部门提供的气象数据缺少湿球温度参数,影响了工业冷却塔的设计优化。为了提高冷却塔设计的准确性以及计算效率,采用非线性曲面拟合方法以及二分法求解湿球温度,提供了拟合方法的详细公式以及二分法求解的源代码。在标准大气压下,两种计算方法的误差最小,气压越低,误差越大;相对湿度越高,两种计算方法的误差越小。计算结果表明,拟合法求得的湿球温度稍差,但能满足工程设计要求;二分法求解方法简便,精度高,计算源代码的可移植性高。研究结果可为相关工程设计提供参考,具有一定的实践意义。     

Some Simple Economics of Open Source

There has been a recent surge of interest in open source software development, which involves developers at many different locations and organizations sharing code to develop and refine programs. To an economist, the behavior of individual programmers and commercial companies engaged in open source projects is initially startling. This paper makes a preliminary exploration of the economics of open source software. We highlight the extent to which labor economics, especially the literature on 'career concerns', and industrial organization theory can explain many of these projects' features. We conclude by listing interesting research questions related to open source software.     

Code and conduct in French cuisine: Impact of code changes on external evaluations

We study the effects of organizational code‐preserving and code‐violating changes on external evaluations by third parties—an essential but under‐studied strategic outcome. We define code‐preserving changes as a variation in the firm's product range that preserves the social code within which the firm positions its offering. By contrast, a code‐violating change corresponds to a variation in the product range that breaks with past codes and embraces another social code. Our analyses of French haute cuisine restaurants show that code‐preserving changes and code‐violating changes have positive effects on external evaluations. Both effects decline with prior evaluations received by the organization, but only the effect of code‐violating changes is reduced with age. Moreover, external evaluations improve when restaurants undertake more code‐preserving changes than their direct competitors but decline when they make more code‐violating changes than competitors. These results enable us to derive implications for research on strategic change, strategic groups, and strategic social positioning. Copyright © 2007 John Wiley & Sons, Ltd.

The infant formula debate

Two articles on ‘The baby milk controversy’, published in the August 1980 issue of Food Policy, were received with great interest and have generated a large response. In those articles, John Sparks put the case for the infant formula manufacturers and Andy Chetley replied. We now present the comments of a Third World scientist in response to those articles, a report from Andy Chetley on the international marketing code for breast-milk substitutes, and an appeal by Jennifer Halpern for increased cooperation between the multinationals and INFACT and its supporters.     

压缩格式和码率对视频质量的影响及应用研究

随着视频技术的发展,对能以最少的数据量获得最好的视觉效果的研究具有重要意义。对于视频质量而言,视频压缩格式及码率无疑是两个最重要的参数。本文通过对高清视频进行压缩,得到相同压缩格式不同码率和相同码率不同压缩格式的视频,然后分别对这两种情况下的视频质量进行主观评价值、PSNR值以及数据量的比较,分析其对视频质量的影响。最终得出结论,在视频压缩过程中,存在一个最高临界码率,使得视频质量相对最高且数据量最小。此外,还总结出各种常用视频压缩格式的适用范围。     

Symbolic or substantive document? The influence of ethics codes on financial executives' decisions

With the recent spate of scandals resulting from the questionable behavior of corporate leaders, there have been calls for various governance mechanisms including ethics codes to guide executive decision‐making. However, the extent to which ethics codes are actually used by executives when making strategic choices as opposed to being merely symbolic is unknown. We develop our hypotheses by combining stakeholder management theory and the theory of planned behavior, and test them with a survey of 302 senior financial executives (e.g., CFOs, VPs of Finance). We find that financial executives are more likely to integrate their company's ethics code into their strategic decision processes if (a) they perceive pressure from market stakeholders to do so (suppliers, customers, shareholders, etc.); (b) they believe the use of ethics codes creates an internal ethical culture and promotes a positive external image for their firms; and (c) the code is integrated into daily activities through ethics code training programs. The effect of market stakeholder pressure is further enhanced when executives also believe that the code will promote a positive external image. Of particular note, we do not find that pressure from non‐market stakeholders (e.g., regulatory agencies, government bodies, court systems) has a unique impact on ethics code use.

The Value of Building Codes

We present a double moral hazard model to study the impact of building codes on the safety/quality level chosen by the builder and the level of care expended by the buyer. We show that codes can be a mechanism to implement the first-best solution provided: (1) The code prescribes the optimum safety level, (2) The code uses the efficient technology to achieve the optimum safety level, and (3) The courts use Negligence Rule as the liability rule. We argue, however, that codes in general do not use the efficient technology. We provide an alternative mechanism to implement the first-best solution. This mechanism is a contract between the builder and the buyer that specifies the level of safety jquality to be expended by the builder. We prove that the contract is a more effective and more efficient mechanism than are the building codes.
