我国养老金双轨制改革问题探析

我国养老保险双轨制是我国计划经济体制向市场经济体制转型时期的产物,是指企业与机关事业单位采取两种不同的养老体系。随着经济的发展,双轨制的弊端越来越明显,已成为阻碍社会公平实现的因素之一。     

铁路车站站内计轴轨道电路抗干扰方案的探讨

铁路车站站内计轴轨道电路由工务施工造成干扰是普遍存在的问题.通过对铁路车站站内计轴轨道电路几种抗干扰方案的研讨,阐述了各方案的特点,比较得出最优方案,即利用计轴点相邻轨道区段的状态和时间双重条件,对计轴轨道区段内“±1轴”进行冗余设计,以提高站内计轴设备的抗干扰能力,使设备的安全性得到保证.     

马克思主义哲学中国化的历史轨迹与当代的规范表达

马克思主义哲学作为全部马克思主义的思想基础,其中国化是整个马克思主义中国化的前提和重中之重,而唯物论和辩证法是马克思主义哲学的精粹,马克思主义哲学的中国化主要就体现在唯物论和辩证法的中国化上。在民主革命时期,毛泽东以其实事求是和对矛盾的全面解说开唯物论与辩证法中国化的先河。在改革开放的新时期,邓小平以解放思想实事求是和对对立面和谐合作关系的阐发开创了马克思主义哲学中国化的新阶段。新一代中央领导集体提出的以人为本和构建和谐社会把唯物论和辩证法的中国化推进到一个新的制高点。伴随着时代和任务的转换,马克思主义中国化在新时期被表述为马克思主义中国化、时代化、大众化。中国化是主题或称一体,其内涵仍是马克思主义与中国具体实际相结合,而在其结合过程中,要特别关注时代化和大众化,这是两翼。一体两翼就是马克思主义中国化在当代的规范表达。     

关于动车组列车新型轨道的研究

随着高速动车组列车的引进和开发及车速的不断提高,列车对轨道的要求也越来越高。普通的双轨无砟轨道对路基的沉降量要求很高,并且在强烈的暴风力作用下,高速行驶的列车容易脱轨,引发严重交通事故。为了满足时速200km以上的动车组列车安全运行,论文汲取了悬挂式单轨交通和双轨无砟轨道的优点,设计了三相无砟轨道,从而保证了高速列车运行的安全性。     

The Impact of Brand Relationship and Attributions on Passenger Response to Service Failure

It is important for service companies to develop and maintain consistent and stable consumer loyalty. Although consumer brand relationship and attributions have been applied to various service industries, they have not been investigated in the airline industry where passenger emotions are considered critical. This study addresses the consequences of brand relationship quality, the mediating influence of emotions, and the moderating role of switching costs through structural equation modeling of data collected from passengers who had experienced flight delay. The results suggest that (1) airline relationship with passengers is an important and valuable asset, especially in the case of stability attributions, (2) negative emotions play a partial or full mediator role in the causal relationship between attributions and behavioral intentions, and (3) minimizing negative emotions is more effective than relying on switching costs for behavioral intentions. It can be concluded that the airline industry should try to manage passenger emotions more appropriately since passengers have an emotional attachment to their brands and passengers' negative emotions can be influential to repurchase intentions when service failures occur.     

Strategic Asset Allocation for China＇s Foreign Reserves： A Copula Approach

In this paper, we study strategic asset allocation for China＇s foreign reserves using a risk- based approach. Four aspects of the risk management are investigated： an investment universe, dependence structure, allocation strategies under risk minimization and trade-off between risks and returns. A regime-switching copula model is developed to investigate the dynamic dependence between assets. One regime emphasizes a short-term safe asset and the other regime emphasizes a long-term safe asset. The optimal allocation is derived following two strategies： risk minimization and trade-off between risks and returns in utility maximization with disappointment avoidance, lf the central bank focuses solely on risk minimization, the asymmetries in the asset return dependence encourage the flight to safety. However, if higher risks are allowed in exchange for higher returns, even the exchange is very conservative, and the asymmetries would discourage the flight to safety. Therefore, we suggest that China should mitigate its flight to safety after 2008 and increase holdings of short-term bank deposits, long-term treasury bonds and euro bonds.     

物态波形论——《自由运动论》在实际中的应用（7）

由于粒子运动速度很快，所以观察时，只能观察到其波动形的运动轨迹。由《物态球形论》的理论可知，波动形的运动轨迹就是粒子的一种形态。即波形也是物质的一种形态。     

An Investigation of the Flight-to-Quality Effect: Evidence from Asia-Pacific Countries

Flight to quality has long been a feature of international financial markets when there are extreme variations in the negative relationship between returns on stocks and sovereign bond indices. This study analyzes the existence of a flight-to-quality effect from stocks to long-term government bonds in five Asia-Pacific countries by modeling a dependency structure from a copula-based perspective. The authors employ various copula functions to examine the degrees of dependence on symmetric and asymmetric structures in these countries. They find a negative relationship between stock and bond returns, that there is a flight to quality in the Asia-Pacific region, and that it intensified during the financial crisis period, indicating that investors considered government bonds to be safer financial instruments than stocks during this period. Furthermore, the authors show that the level of economic freedom in a country affects the tendency toward flight to quality.     

Effect of Capital Flight on Investment: Evidence from Emerging Markets

Much of the discussion on international capital movements is directed toward studying the effects of foreign capital flows, whereas the implications of resident capital outflows (capital flight) from developing countries remain largely unanalyzed. Using a dynamic panel methodology for twenty-two emerging market economies between 1975 and 2000, this paper investigates the effect of capital flight on investment and how this effect changes with financial liberalization policies. The empirical findings indicate that capital flight reduces private investment dramatically but does not have any effect on public investment. However, no statistically significant impact of financial liberalization on the marginal effect of capital flight on investment is found.     

How does economic policy uncertainty drive gold–stock correlations? Evidence from the UK

In this article, we investigate the effects of economic policy uncertainty (EPU) on correlations between the UK stock market and gold market. We find that less certain economic policies result in lower correlations, while more certain economic policies result in higher correlations. The correlations are symmetric and show no structural breaks caused by the recent financial crisis. The recent financial crisis has not changed EPU effects on the correlations. The effects of one positive one-standard-deviation shock of the logarithmic change rate of the EPU on the correlations last approximately 19 months.
