浅谈在后续检定中气体检测仪漂移检定的必要性

通过对非矿井作业环境中使用的气体检测仪的检定,发现部分气体检测仪的零点示值和检定示值超差,即零点漂移和量程漂移超差,需要重新调整后才能合格,其中部分气体检测仪经调整后仍然达不到合格标准。但是检定规程中只要求首次检定时做零点漂移和量程漂移检定项目,忽视了后续检定中气体检测仪零点漂移和量程漂移项目的检定。从气体检测仪工作原理、漂移产生的原因等几个方面分析,论证了在气体检测仪后续检定中漂移检定的必要性。     

Can Stock Markets Predict M&A Failure? A Study of European Transactions in the Fifth Takeover Wave

In this paper we develop various measures of M&A failure for an intra‐European sample during the fifth takeover wave: inferior long‐term stock performance, inferior operating performance, and target divestment. After documenting the extent of M&A failure, we test the relation between short‐term abnormal returns at deal announcement and M&A failure. We examine a sample where listed bidders acquire listed targets (267 deals) as well as privately‐held targets (336 deals). Our results indicate M&A failure rates up to 50% in both samples. When acquirers and targets are listed, lower M&A announcement returns are consistently and significantly associated with higher M&A failure probabilities and long‐term losses. In contrast, when targets are privately held, we find no evidence of such an association.     

The puzzling behavior of short sellers around earnings announcements

We examine the performance of ‘predictive’ and ‘reactive’ short sellers who take relatively large short positions immediately before and after quarterly earnings announcements, respectively. While both types short into advancing markets, it is surprising for reactive shorts since their trades are in stocks that just announced unexpected good news and thus, according to the post-earnings announcement drift anomaly, will subsequently have abnormally high cumulative returns. Nevertheless, we find that for both types of short sellers: (1) subsequent cumulative returns are significantly negatively related to the amount of abnormal short selling, suggesting they are informed, and (2) relative to non-earnings dates, the subsequent returns around earnings announcements are significantly more negative, indicating they appear to be adept at exploiting earnings announcements. Surprisingly, we find that the subsequent returns of reactive short sellers are significantly greater than those of predictive short sellers except for S&P 500 stocks, perhaps due to their greater analyst following. Importantly, we are left with two puzzles. First, reactive shorts would have significantly improved their performance had they based their trades on the size of standardized unexpected earnings (‘SUE’). Second, predictive shorts of Micro stocks would have significantly improved their performance had they simply waited until earnings were announced and then based their trades on SUE.

中国开放式基金风格漂移与业绩相关性的实证研究

以中国开放式股票型和债券型基金为样本,通过对基金风格漂移程度的量化,检验基金风格漂移、资金流波动、基金规模及基金费率与基金业绩之间的关系,即可发现风格漂移的程度与基金的业绩呈正相关,但与资金流波动不相关;同时,基金规模与基金的业绩呈正相关,与费率呈负相关．     

国家治理视角下的绩效审计问责制度构建

绩效审计问责制度是指根据一系列指标对政府使用公共财政资金的绩效性进行评价考核,并将考核结果与责任追究结合起来的一种制度。完善的绩效审计问责制度是完善国家治理,提高公共资源使用和管理效率,建设廉洁、高效的服务型法治政府的必然要求。当前,应根据国家治理的新要求,建立多元国家治理主体下的绩效审计“异体问责”主体制度、组织问责与个人问责相结合的问责客体制度、主客观标准并重的问责条件制度、行政责任与法律责任相结合的责任承担制度以及有关配套保障制度。

南京国民政府时期政府审计独立问题探析

南京国民政府在立法层面上构建了相对完善的政府审计独立制度,在“监审合一”框架内,南京国民政府通过宪法和审计法在审计机关职权划分、审计人员、审计行为等方面对政府审计独立制度进行了规定和保护,形成了较完备的政府审计独立制度。但由于南京国民政府反共反人民的本质,其设置的政府审计独立制度难以真正发挥实效。当前我国正在完善党和国家监督体系框架内修改审计法,如何通过修法最大限度地实现审计机关依法独立行使审计监督权,对包括南京国民政府时期审计制度在内的各方面历史和现实的经验教训进行总结可以提供借鉴。
