The great moderation in micro labor earnings

Between 1980 and the early 1990s the variability of labor earnings growth rates across the prime-age working population fell significantly. This decline and timing are consistent with other macro and micro observations about growth variability that are collectively referred to as the “Great Moderation.” The variability of earnings growth is negatively correlated with age at any point in time, and the U.S. working age population got older during this period because the Baby Boom was aging. However, the decrease in variability was roughly uniform across all age groups, so population aging is not the source of the overall decline. The variance of log changes also declined at multi-year frequencies in such a way as to suggest that both permanent and transitory components of earnings shocks became more moderate. A simple identification strategy for separating age and cohort effects shows a very intuitive pattern of permanent and transitory shocks over the life cycle, and confirms that a shift over time in the stochastic process occurred even after controlling for age effects.

丁草胺在水环境中降解规律的研究

论述了pH值、微生物、太阳光照和温度对丁草胺在水样中降解的影响。结果表明。影响丁草胺在水环境中降解的因素依次为pH值、微生物、太阳光照和温度。太阳光照的影响程度较低，而pH值、微生物和温度的影响程度较高。水中的OH^-会对丁草胺的降解有催化作用，另外，水中存在的微生物可加快丁草胺的降解速率；丁草胺在温度较高条件下降解的速率较快。

Paths to Success: How Do Market Orientation and Entrepreneurship Orientation Produce New Product Success?

The purpose of this paper is to examine the relationship between strategic orientation and the performance of new products. In this paper, we develop a conceptual model that explores the roles of market orientation (MO) and entrepreneurship orientation (EO) on new product performance and seek to understand the mediating roles of process and product characteristics. Based on a survey of 471 small and medium‐sized enterprises in Korea, we found that MO and EO positively affect new product performance. The main impact of MO is through new product development proficiency and product meaningfulness and that of EO is through proficient intellectual property management and product novelty. Academic and managerial implications are also discussed.     

从二元结构看王国维《〈红楼梦〉评论》的艺术价值观

旅游活动助益游客心理健康——基于调查数据的实证分析

心理健康问题得到当今社会的极大关注,旅游有助于改善人们的心理健康,学界也进行了相关探讨。采用汉密尔顿焦虑量表（HAMA）与汉密尔顿抑郁量表（HAMD）对89例游客的焦虑状态和72例游客的抑郁状态在旅游前后进行测评,并运用SPSS 20.0进行检验和比对,研究旅游对于改善人们焦虑、抑郁情绪的影响。研究结果显示：1.游后焦虑情绪较游前有显著降低,而抑郁情绪改善不明显;2.景观类型选择对游客焦虑改善存在显著差异;3.旅游时间长短与游客焦虑存在负相关关系。     

中国城市更新运行机制失衡分析

在当前中国进行的城市更新中,大部分的更新过程和机制都存在着失衡问题,无论是在城市更新的信息过程还是在激励以及利益的分配等过程中,越来越多的问题需要我们去关注。城市更新的机制失衡问题会严重影响资源配置的效率以及城市更新的效益,文章以当前城市更新的失衡问题为出发点,就当前中国城市更新中暴露出来的信息失衡、激励不相容、利益分配冲突以及其他制约因素进行分析,并探讨优化管理的策略。
