High Precision CAE Analysis of Automotive Transaxle Oil Seal Leakage

The manufacturing industry today due to worldwide competition is focused on shorter development cycle. In this situation, computer aided education （CAE） technology as a tool for simultaneous achievement of quality, cost and delivery （QCD） plays an important role. The hardware-software environment surrounding CAE has evolved. Though technological problems have been understood and general solutions have been derived and reflected in the CAE analysis software, research findings that boost the credibility of CAE have still not been incorporated fully enough into the development of design process. The real technical mechanism issue is not precisely capture. Therefore, it is important to clarify the real cause in CAE results through CAE simulation in order to assure product reliability and assurance. It is the aim of this study to realize the prediction of design analysis process through understanding of unclear technical mechanism in abnormal occurrences with the utilization of CAE simulation. In other words, it is the aim of this study to focus on issue in automotive transaxle oil seal leakage to understand, grasp, and visualize the main cause through usage of CAE analysis process. It is understood that the point of contact and pump volume was related and this could contribute towards seals quality design. Plus, the utilization of CAE analysis in prediction phase to realized design development is also possible     

沪深300指数期货价格随机利率效应研究

经典持有成本模型在非随机利率假设无法满足的条件下仅仅是远期合约而非期货的定价模型。本文采用拟合SHIBOR曲线的方法生成无风险纯折现债券模拟价格序列,对沪深300指数期货价格的随机利率效应进行了实证检验。研究结果表明,由于利率管制、股指期货市场和货币市场发展不成熟等因素的共同作用,沪深300指数期货价格中不含随机利率效应,指数远期和期货理论价格相等;如果持有成本模型其他假设条件也得到满足,则该模型可以用于沪深300指数期货定价。

Interventions and Japanese economic recovery

This paper attempts to explain possible reasons and objectives behind the 35 trillion yen (7% of GDP) interventions conducted by the Japanese monetary authorities from January 2003 to March 2004, and to discuss whether the interventions achieved the presumed objectives: making the movement of the yen flexible but orderly, and helping economic recovery. The motivation of starting intervention in January 2003 was to keep the yen from appreciating in the midst of financial and macroeconomic weakness. The economy started to show some strength in the second half of 2003, but interventions continued, with a brief pause in September. Reasons for interventions after September are twofold. First, the interventions provided opportunities for unsterilized interventions. Second, the monetary authorities were extremely sensitive to speculative activities in the market.     

我国碳排放权市场发展路径之研究

对国内外碳排放权市场的运行机制和发展状况进行了分析,剖析了各种碳排放权市场机制的特点,并创造性地将其与我国国情相结合,探讨了我国碳排放权市场的发展路径。现阶段我国尚未完全具备建立强制性减排交易市场的基本条件,但是鉴于未来碳排放权市场的重要性,我国应该把发展碳排放权市场作为一项长期战略。我国碳排放权市场可以采取如下发展路径:第一步,培育和壮大我国自愿抵消市场;第二步,借鉴美国经验发展类似CCX的会员制自愿减排交易市场,同时借鉴印度经验适当发展CDM单边项目并以此为基础建立CDM二级市场;第三步,在条件成熟的情况下推出强制性减排交易市场。     

Does supporting employees' career adaptability lead to commitment,turnover, or both?

Today, employees are encouraged to become more career‐resilient and engage in career development activities to deal with changes in required knowledge, skills, and abilities, and to facilitate their mobility. This study found that participation in decision making (PDM) and autonomy, along with supervisory career support (information, advice, and encouragement), fostered this career adaptability. These practices were also positively associated with commitment and negatively with intentions to leave. However, career adaptability was positively associated with both commitment and intentions to leave, suggesting some unintended consequences for management approaches supporting career adaptability. Implications for research and practice are discussed. © 2005 Wiley Periodicals, Inc.     

The rise and fall of deficit in Japan, 1965–1990

This paper investigates the fifteen-year period when the Japanese government deficit (defined as the deficit bond issues to the general budget) rose sharply and shrank to zero. Our main contribution is to differentiate the budget “plan” and the “actual” (ex post) budget in order to distinguish intention and surprise. From 1976 to 1979, deficit bonds were considered to be deliberately increased, because of little surprise (deviations of actual from planned budget) in deficits for these years. The deficit ratio was brought down in the 1980s, mainly by freezing expenditures at the nominal level and waiting for bracket creeps in taxes to catch up. Beyond a trend increase in the 1970s and a trend decrease in the 1980s, the Japanese government acted to pursue a fiscal expenditure fine-tuning.
