The rise and rise of IFRS: An examination of IFRS diffusion

We seek to understand the ever-increasing push towards the international harmonization of accounting standards and particularly the inexorable rise of standards produced by the International Accounting Standards Board (IASB). While the primary justifications for the increasing recognition given to these standards (IFRS) are economic, we question whether the empirical evidence to date has yielded convincing support for these arguments. We therefore offer an alternative explanation for the origin and diffusion of IFRS that incorporates social and political factors. Outsourcing the manufacture of accounting standards to a single private agency appears to be a rational, lower cost option – lowering both economic and political costs for individual states as long as they continue to retain residual decision rights with respect to the adoption of IFRS. However, such outsourcing must also be perceived to be legitimate. IFRS confer institutionalized legitimacy because they possess three characteristics required of a technology for global governance. These are sponsorship by powerful interest groups/regulators, internationality and plasticity. We therefore conclude that the widespread diffusion today of IFRS can at best be only partially explained as an economically rational phenomenon. Rather, the demand for legitimate action in the face of tightly coupled and complex global markets is at least equally important in generating support for IFRS.

The re-emergence of the public accounting profession in China: A hegemonic analysis

This paper draws on Gramsci's concept of hegemony to examine and explain the circumstances leading to the re-emergence of the public accounting profession in China in the early 1980s. In particular, the paper attempts to understand the political and ideological influence upon the professionalisation process of the Chinese accountants. The paper not only highlights a major difference between the professionalisation process of the public accounting profession in China as compared to the West, but also the authoritative and dominant role assumed by the Chinese state in the whole societal set-up. Through effectively exercising its political and ideological leadership, the state successfully mobilised the Chinese accountants in the implementation of its economic-related agenda. The paper demonstrates that the state has clearly achieved hegemony within the accounting community, and further suggests that the state-accounting profession relationship could be likened to the father–son relationship as encompassed within the Confucian notion of wu lun.     

Value at risk and conditional extreme value theory via markov regime switching models

This study develops a new conditional extreme value theory‐based (EVT) model that incorporates the Markov regime switching process to forecast extreme risks in the stock markets. The study combines the Markov switching ARCH (SWARCH) model (which uses different sets of parameters for various states to cope with the structural changes for measuring the time‐varying volatility of the return distribution) with the EVT to model the tail distribution of the SWARCH processed residuals. The model is compared with unconditional EVT and conditional EVT‐GARCH models to estimate the extreme losses in three leading stock indices: S&P 500 Index, Hang Seng Index and Hang Seng China Enterprise Index. The study found that the EVT‐SWARCH model outperformed both the GARCH and SWARCH models in capturing the non‐normality and in providing accurate value‐at‐risk forecasts in the in‐sample and out‐sample tests. The EVTSWARCH model, which exhibits the features of measuring the volatility of a heteroscedastic financial return series and coping with the non‐normality owing to structural changes, can be an alternative measure of the tail risk. © 2008 Wiley Periodicals, Inc.

蒙脱石散剂治疗小儿腹泻的临床疗效

目的探讨蒙脱石散剂治疗小儿腹泻的临床疗效。方法选取住院治疗的腹泻患儿86例,随机均分为对照组与观察组,各43例。对照组患儿给予抗病毒、抗炎治疗、液体疗法及对症治疗等常规治疗;观察组患儿在常规治疗的基础上给予口服蒙脱石散剂治疗。比较两组患儿的临床疗效及胃肠道不良反应发生情况。结果治疗72 h后,观察组患儿的治疗总有效率为95.3%,1例(2.3%)发生胃肠道不良反应;对照组患儿的治疗总有效率为81.4%,7例(16.3%)发生胃肠道不良反应;观察组明显优于对照组,差异均有统计学意义(均P<0.05)。结论给予患儿口服蒙脱石散剂治疗儿科腹泻可加强常规治疗的临床治疗效果,同时减少胃肠道不良反应的发生。     

Effect of Order of Contribution in a Sequential Public Goods Dilemma

This study examined how order of contribution in a sequential public goods dilemma affected cooperation. Under a sequential protocol of play, players of different levels of efficacy made decisions one after another. We contrasted a High-to-low versus Low-to-high Efficacy order in a nine-person game. Under a High-to-low order, high-efficacy players made decisions in positions 1–3, medium-efficacy players in positions 4–6, and low-efficacy players in positions 7–9. Under a Low-to-high order, the positions of high- and low-efficacy players were reversed. We hypothesized that cooperation rates would be higher in the High-to-low order that high-efficacy players (assigned in early positions), who would likely cooperate, would induce subsequent players to cooperate also. We found the anticipated effect that cooperation rate was higher in the High-to-low than the Low-to-high efficacy order. The efficacy order effect was the most prominent when people perceived that their group was becoming uncooperative. This study illustrates a new type of structural solution to social dilemmas that by systematically assigning people to different sequential positions, a group can be made more or less cooperative.     

农村社会养老保险制度分析——以北京市大兴区为例

农村社会养老保险能否建立并保持可持续发展,仅仅依靠需求动机是不够的,还需要政府的态度、财政能力、农民的意愿、制度设计的合理性等多方面条件。结合北京市大兴区农村社会养老保险试点方案,对上述问题作了简要分析。农村全面实行社会养老保险制度的时机还不够成熟。从防范老年贫困风险的角度出发,对处于贫困线以下的人群提供最低收入保障,尽快建立农村最低生活保障制度和完善农村社会救助制度是目前大多数农业地区比较理性的选择。     

BUYERS,SELLERS, AND MIDDLEMEN: VARIATIONS ON SEARCH‐THEORETIC THEMES

We study exchange that is bilateral but indirect—it involves chains of intermediaries, or middlemen—in markets with frictions. These frictions include search and bargaining problems. We show how, and how many, intermediaries might get involved in a chain, and how bargaining with one depends on upcoming negotiations with those downstream. The roles of buyers, sellers, money, and prices are discussed, allowing us to clarify some neglected connections between different branches of search theory. Pursuing one such connection, with monetary economics, we show how bubbles can emerge in intermediation, even with fully rational agents and perfect foresight.     

一种多信道的分簇式短波令牌协议

传统的短波令牌协议（HFTP）调度方式单一,在没有数据传送时,信道资源会被各节点间的令牌传递所占用,且令牌在通信质量较差时易丢失。基于此,提出一种多信道的分簇式短波令牌协议（CHFTP）,通过以通信质量评估为标准的分簇算法和基于预约的动态令牌调度,减小了令牌丢失的概率和令牌传递、处理的开销,并给出了仿真分析。仿真结果表明,该协议的端到端平均时延和网络吞吐量明显优于短波令牌协议,CHFTP的平均时延最多可减少75%,网络吞吐量最多可增加66.7%,适合在短波通信网络中使用。
