结合古典文献上的移民记载与实验语音学、音韵学、方言学对高邑方言进行探讨。认为高邑话属于晋语次方言 ,源于明初的山西移民 ;其 - n尾向 - i的转化 ,有着语音特征上的共同性 ;而阳平与阴上的合流则是由入声独立成一调推动的结果  相似文献

《庄子》养生思想是其整个哲学思想的有机组成部分,《庄子》的哲学世界观、人生价值观、人体生命观及健康观决定了其养生思想的基本风貌。《庄子》的养生思想体现在万物生于阴阳的世界观、"精神生于道"的生命观与"形本生于精"的身体观、"因自然而不益生"的养生原则、"缘督以为经"的中和养生方法论、"心斋"、"坐忘"的养气论、"形全精复"的养神论等六个方面。  相似文献

我国资源价格重构的理论思考与机制探讨   总被引:2,自引:0,他引:2  
要推进经济增长方式转型,资源价格重构势在必行。文章首先归纳了资源价格扭曲的内外症状,并剖析了症结和危害;认为就整体而言,价格重构应侧重于矫正内部扭曲;就结构而言,只能定位于部分地消除资源内外比价的失调;基于可持续发展视角下对资源价值及其构成的理论探讨,既剖析了我国资源价格扭曲的实质,又深入探讨了资源价格的基本改革图景;最后,从理论上指出了边际机会成本定位法的严重不足,强调我国资源价格重构应该采取现实可行的"实际补偿顺推法",并立足全局,给出了对策建议。  相似文献

库存水平影响需求的变质性产品的供应链协调模型   总被引:1,自引:1,他引:1  
在考虑市场需求是库存水平线性分段函数、变质性产品和零售商采用(S,s)订货策略的情形下,本文研究了由一个供应商和一个零售商构成的供应链系统运作协调问题。给出了可以实现供应链完美协调的数量折扣策略,理论证明了模型最优解的存在性和唯一性,同时提供了相应的求解方法。数值算例结果表明该折扣模型对于改善供需双方绩效和供应链运作协调是十分有效的。  相似文献

The starting point of this study is the implementation of seemingly similar youth‐oriented labour market policies in Greece and Portugal. Both countries have suffered high youth unemployment rates and have been pressured to restructure their labour market as part of the rescue programmes adopted during the European sovereign debt crisis. Despite convergence in terms of policy trajectories, there is a significant divergence in employment outcomes. In Portugal, youth‐oriented policies were better‐targeted and structured. Their implementation has been more effective and has involved the social partners from the outset of the crisis. In Greece, policy design failures, administrative weaknesses and unfavourable macroeconomic conditions have limited the dynamics of youth‐oriented policies thus increasing youth insecurity. Τhe analysis suggests that convergence in policy content can be compatible with divergence in terms of outcomes.  相似文献

This article examines the relationship between human emotions and slavery in Chos?n Korea (1392–1910) by examining legislative processes as well as private practices concerning the status of the offspring of a yangban man and his slave-status concubine. The legislative discussions and decisions on the topic at the royal court often subscribed to the notion that these children were also the yangban’s ‘flesh and blood’ and called for compassion, a Confucian emotional norm expected of parents. When yangban fathers manumitted their slave-status children, they recorded their feelings in the same affective language expressed in the legal discourses. Yet, because slaves were among the yangban’s most valuable possessions and yangban elites regarded the maintenance of social hierarchy as the key for social order, legal paths for manumission were narrowly defined and emotional norms did not always dictate parents’ actions. By investigating the larger legal framework related to slave-status children of yangban elites alongside specific cases, this study seeks to provide a deeper understanding of the historical impact and practices of emotional politics in relation to slavery. It finds that the yangban fathers’ very primordial human emotion towards their own children was stratified by social and economic conditions and selectively applied.  相似文献

Abstract

We consider the classification of high-dimensional data under the strongly spiked eigenvalue (SSE) model. We create a new classification procedure on the basis of the high-dimensional eigenstructure in high-dimension, low-sample-size context. We propose a distance-based classification procedure by using a data transformation. We also prove that our proposed classification procedure has consistency property for misclassification rates. We discuss performances of our classification procedure in simulations and real data analyses using microarray data sets.  相似文献

This article investigates to what extent instrument substitution between early exit pathways took place in Europe between 1995 and 2015. Using Eurostat aggregate data on labour market inactivity and employment rates among the population aged 55–64 in 19 European countries, we analyse substitution effects between pathways and overall spill-over effects into non-employment. In spite of a strong decline in early exit and rises in older workers’ employment rates, findings suggest that instrument substitution was common especially between early retirement and disability. Reductions in early exit coincided with considerable spill-overs into non-employment, yet these spill-overs were limited when pathways contracted simultaneously.  相似文献

China has made a number of major changes to its pension system in the period 2014–2020, and is in the process of establishing a multi‐tier old‐age pension system, consisting of programmes provided by the government, voluntary programmes provided by enterprises, and voluntary programmes established by individuals. Policy objectives are to reduce the fragmentation in its pension system; deal with population ageing; and diversify risks by involving the government, enterprises as well as individuals. This article shows that while China has a complex system for urban workers, the coverage provided by its multi‐tier system is uneven, with the second and third tiers being in the early stages of development.  相似文献
