唐诗三种创作主题与西域器乐文化关系的流变考释

唐诗中有三类创作主题与西域乐器有密切关系:昭君出塞与琵琶、文姬归汉与胡笳、公无渡河与箜篌。这种关系在被不断误读的过程中丰富、深化和变异。     

Self-selection and the performance of return migrants: the source country perspective

In this paper, using the framework of a Roy theoretical model, we examine the performance of return migrants in Albania. We ask two main questions: (i) Had they chosen not to migrate, what would be the performance of return migrants compared to the non-migrants? and (ii) What would be the performance of non-migrants had they decided to migrate and return? Both the selection estimates and the semi-parametric approach allow us to conclude that the flows of return migrants are negatively selected. We find that, had they decided to migrate and come back, the non-migrants would have earned more than twice the wages of return migrants.     

养老基金投资的不确定性与投资组合分析

在中国个人账户基金积累规模日益扩大的情况下,有限的投资工具和较低的回报率将难以实现这部分基金的保值增值,也很难为退休人口提供一个适度的养老金替代率水平。中国养老基金的投资组合策略有其自身的特点。首先,对一个简化的投资风险最优模型进行了分析;其次,利用风险最优模型研究了养老基金的投资组合,并确定了股票投资的最优水平;最后,针对中国养老基金的投资策略提出相关的政策建议。     

中国大豆期货收益GARCH效应的实证研究

文章研究了中国大连商品交易所大豆期货连续合约1994-2003年收益时间序列,并以该序列2003年第一个样本数据为分界点,建立了两子序列,分别进行了统计学分析,发现两子序列分布均是非正态的,较正态分布有尖峰厚尾的特征,具有记忆效应。并且,进一步根据两子序列的波动集群性建立一系列GARCH模型,对中国大豆期货的两个收益序列的波动性进行分析,并比较了二者的异同。     

关切民生:马克思主义大众化的生活回归

推进马克思主义大众化,是当下中国共产党思想理论建设和政治建设的重大战略举措.作为“改变世界”的实践主体,现实的个体的人的生存与发展,是马克思主义一个不容忽视的传统和题中应有之义.正是基于对民生的高度关切,马克思主义唯物史观得以形成;也正是基于对民生的高度关注,马克思主义得以在中国成功传播.当下的中国,民生问题已成为人民大众最关心的现实矛盾,民生矛盾的解决程度已经同马克思主义大众化的实现程度密切相关.人民是马克思主义大众化的主要推动者和受众,更是推动马克思主义不断创新发展的主体.马克思主义只有回归到人民大众的生活世界,充分尊重人民大众作为历史主体的出场者地位,理性面对差异性社会的特征,不断满足人民大众的利益需要,高度重视对人民大众的人文关怀,才能在不断撞击人民群众心灵的过程中,获得广大人民群众内心深处基于自觉自愿的接受和认同,马克思主义大众化才能真正得以实现.     

模糊环境下基于信息熵风险度量的投资组合模型

研究了模糊环境下的投资组合模型,将证券的收益率描述为模糊变量,运用信息熵度量投资风险,分析了模糊熵度量模糊环境下的不确定性的优点,提出了模糊环境下基于信息熵风险度量的投资组合模型,设计了基于模糊模拟的混合智能算法对具有模糊收益的投资组合模型进行求解.     

论控股公司的风险与回报率

在完备的资本市场中,控股公司并不能给股东带来更多的好处,因此它并没有存在的依据;在非完备的资本市场中,控股公司通过多样化投资,能够在同等风险水平上增加小投资者的财富或者在相同回报率的水平上降低小投资者的投资风险。控股公司多层控股使整个控股公司体系的财务杠杆比率很高,因此控股公司实质上采取了高财务风险、高回报率的融资政策。     

《高祖还乡》的陌生化解读

“陌生化”意味着“使其陌生”，是俄国形式主义诗学的核心概念，它昭显了俄国形式主义的纯艺术观。以“陌生化”为基点，俄国形式主义构建了一个自主性的文学理论体系。在《高祖还乡》中，睢景臣通过陌生化的艺术处理，对传统的根深蒂固的文化正统和帝王权威进行了成功的颠覆，使接受主体摆脱了机械化的定势的感知模式，以一种全新的眼光和视角来体验、观照和审视历史。     

A rejoinder to "The impact of infectious diseases on remittances inflows to India"

We argue that the volume of remittances sent home by migrants is influenced by the exogenous likelihood that the duration of their migration will be cut short. A higher probability of reverse migration, brought about by the collapse of jobs in the wake of COVID-19, made migrants attach greater importance to the creation of a social and economic environment in their places of origin that can support them when they return. There are several ways in which this can be done. One is by instilling gratitude. When bigger remittances are responded to by greater gratitude, the support will be bigger. An impact of the COVID-19 pandemic on migrants’ perceived duration of their migration is an increase in the uncertainty of the duration. The good will of migrants’ families and communities at origin is a form of insurance. A standard response to uncertainty is to take out insurance, and when uncertainty is higher, insurance is more valuable, and there is a tendency to acquire more of it. As it happens, the link between the volume of remittances and the likelihood of return migration does not feature at all in Shastri’s (2022) paper, nor for that matter in related writings by the World Bank and the IMF. The purpose of this rejoinder is to draw attention to this link, inducing students of migrants’ remittances to explore the link.
