船用锂电池组管理系统研究

文章以STM32 32位ARM处理器为系统的控制核心,从硬件的角度来分析针对船用锂电池组构成的电池管理系统中的CPU模块,检测模块及均衡模块。该系统可以实现充放电过程中的过充与过放的保护,而且提出了一种较合理的均衡方案。同时对剩余电量作了较准确的估算。     

建设工程项目中信任产生机制研究

建设工程项目中参与单位之间特别是业主和承包商之间的负面关系成为困扰建筑业发展的一大难题.业主和承包商之间存在负面关系,其重要原因是缺乏信任.文章在对信任产生机制进行综述的基础上,提出了建设工程项目中信任产生的因素,即受信方特征和施受信双方关系特征.分析了各项因素对信任产生的作用,并最终构建信任产生机制的概念模型.     

GIS辅助下的河南省高端旅游资源点空间分析

运用GIS的相关软件（Mapinfo7.0）的空间分析功能,对河南省高端旅游资源的空间分布状况进行分析,首先以地市行政中心为点,建立点的缓冲区,在此基础上分析河南省高端旅游资源点相对于地市行政中心的空间分布特征;以河南省内主要交通干线为基轴,建立线的缓冲区,以辅助分析旅游资源点相对省内主要交通干线的空间关系;将点线相结合,总结了河南省旅游资源分布的空间规律,并针对其分布特征给予了综合评价。     

Learning about the Term Structure and Optimal Rules for Inflation Targeting

In this paper, we incorporate the term structure of interest rates in the New Keynesian model and analyze optimal policy under uncertainty about private sector expectations and the degree of inflation persistence. The novel result of our paper is that for large deviations of inflation from its target, the active learning policy is less activist—in the sense of responding less aggressively to the state of the economy—than a myopic policy, which ignores the learning channel. Moreover, for most initial beliefs, the incentive for active learning increases as monetary policy’s leverage over the long‐term interest rate increases.     

杜甫诗歌在越南的接受与传播

梳理了20世纪以前和20世纪至今两个阶段杜诗引进越南院校课堂的历史,探讨越南高等院校在教材、参考资料、课程以及学位论文中所选讲和研究杜诗的情况,分析越南初中、高中学校在教科书和参考资料中所选杜甫《茅屋为秋风所破歌》和《秋兴其一》的讲授方式,指出杜诗在中国诗歌史上的崇高地位、杜诗的精神与越南人民生活体验的契合、越南科举制度对诗歌创作的推动,是杜诗在越南影响深远的原因。     

How Effective Were the Federal Reserve Emergency Liquidity Facilities? Evidence from the Asset‐Backed Commercial Paper Money Market Mutual Fund Liquidity Facility

The events following Lehman's failure in 2008 and the current turmoil emanating from Europe highlight the structural vulnerabilities of short‐term credit markets and the role of central banks as back‐stop liquidity providers. The Federal Reserve's response to financial disruptions in the United States importantly included the creation of liquidity facilities. Using a differences‐in‐differences approach, we evaluate one of the most unusual of these interventions—the Asset‐Backed Commercial Paper Money Market Mutual Fund Liquidity Facility. We find that this facility helped stabilize asset outflows from money market funds and reduced asset‐backed commercial paper yields significantly.     

LOCAL AND STATEWIDE SMOKE‐FREE LAWS IN NEBRASKA: THE EFFECTS ON KENO ESTABLISHMENTS

This study examines how smoke‐free laws influence cross‐border keno shopping in Nebraska. We exploit smoke‐free law variation in timing and location to identify keno revenue gains and losses between neighboring smoke‐free and smoke‐friendly areas. We find the Lincoln municipal smoke‐free law reduced keno revenue by 23.5% in Lincoln and increased keno revenue by 30.0% in smoke‐friendly Surrounding Lincoln counties. The Omaha municipal smoke‐free law reduced keno revenue by 14.8% in Omaha and increased keno revenue by 7.1% in smoke‐friendly Surrounding Omaha counties. Following the Nebraska statewide law, no Nebraska areas had a smoke‐friendly advantage and keno revenue fell by an insignificant 1.0% and 5.2% in the surrounding Lincoln and Omaha counties, respectively. Our results may be of interest to local policy makers interested in understanding the amount of business activity and tax revenue that may be migrating out of a community or even the state.

Earnings Management and Cultural Values

Using theory and empirical data from social psychology to measure for cultural differences between countries, this research studies the effect of individualism, defined as the degree to which individuals are integrated into groups ( Hofstede 1980 ), and egalitarianism, defined as a society's cultural orientation with respect to intolerance for abuses of market and political power ( Schwartz 1994, 2004 ) on earnings management. This research finds a significant cultural influence on earnings management. Specifically, the results show that countries scoring high on individualism tend to have lower levels of earnings management. Using the Schwartz (1994, 2004 ) framework, this study finds that egalitarianism is negatively related to earnings management. The analysis shows that, besides the formal investor protection, it is relevant to consider cultural differences to explain earnings management. This analysis also supports the idea that culture may be an important element in the discussion of global convergence towards a single corporate governance model, or the implementation of corporate governance codes inspired by codes from societies with different cultural values.
