Uniform Test for Predictive Regression With AR Errors

Testing predictability is of importance in economics and finance. Based on a predictive regression model with independent and identically distributed errors, some uniform tests have been proposed in the literature without distinguishing whether the predicting variable is stationary or nearly integrated. In this article, we extend the empirical likelihood methods of Zhu, Cai, and Peng with independent errors to the case of an AR error process. Again, the proposed new tests do not need to know whether the predicting variable is stationary or nearly integrated, and whether it has a finite variance or an infinite variance. A simulation study shows the new methodologies perform well in finite sample.

木偶戏剧在幼儿园活动中运用存在的问题与对策——以山西孝义木偶戏剧为例

木偶戏剧既是我国优秀的非物质文化遗产，同时也是丰富幼儿认知、开阔幼儿眼界的重要教育资源。当前运用木偶戏剧资源开展相关活动的幼儿园数量相对较少，在有限的应用当中也存在教师自身对利用木偶戏剧资源认识不足，木偶戏剧资源利用表面化及形式化等一系列问题。本文根据孝义木偶戏剧独有的艺术特点，从木偶戏剧的欣赏活动、表演活动与制作活动三方面，对如何将孝义木偶戏剧应用到幼儿园活动进行了探讨，为幼儿园运用孝义木偶戏剧这一文化资源组织相关活动提出具体建议。

A new confidence interval in errors-in-variables model with known error variance

This paper considers constructing a new confidence interval for the slope parameter in the structural errors-in-variables model with known error variance associated with the regressors. Existing confidence intervals are so severely affected by Gleser–Hwang effect that they are subject to have poor empirical coverage probabilities and unsatisfactory lengths. Moreover, these problems get worse with decreasing reliability ratio which also result in more frequent absence of some existing intervals. To ease these issues, this paper presents a fiducial generalized confidence interval which maintains the correct asymptotic coverage. Simulation results show that this fiducial interval is slightly conservative while often having average length comparable or shorter than the other methods. Finally, we illustrate these confidence intervals with two real data examples, and in the second example some existing intervals do not exist.

《泰王国民商法典》制定的历史背景

《泰王国民商法典》是在近代泰国法制改革的大背景下产生的，有着复杂的社会历史背景。曼谷王朝拉玛四世以前，泰国历经素可泰王朝、大城王朝和曼谷王朝的一部分，朝代更迭，历时漫长但在法制上却保持了相对稳定。1851年，曼谷王朝四世王拉玛四世（1851-1868）登基，拉开了泰国近代史的序幕。1852年1月，英国在第二次英缅战争之后，占领了缅甸，并觊觎泰国。1855年，英国派其驻香港的总督鲍林率使团到泰国与拉玛四世谈判，威逼泰国于1855年4月18日签订了《英暹条约》（史称《鲍林条约》）。这一个不平等条约彻底打开了泰国闭关自守的大门，欧洲列强以该条约为蓝本，威逼泰国签订了类似条约。泰国自此成为一个半殖民地国家，其法制也逐步西化，泰国的法制也这一时期完成了从古代法制向现代法制的转型。事实上，泰国法制现代化的过程，就是一个从理论到制度逐步西化的过程。《泰王国民商法典》就是在这样一个大的背景下产生的。     

Financial journeys of Australian parents after separation – transitions into and out of poverty

It is well established that relationship separation has greater negative economic consequences for mothers than for fathers in Australia and other developed countries. While research has shown that, at an aggregate level, such negative impacts tend to diminish with time, the rate of change is generally slower for mothers than fathers, and a higher proportion of mothers than fathers continue to experience entrenched financial difficulties. Less is known about the variability of economic journeys experienced by women and men, taken separately, and factors influencing diverse economic trajectories. Drawing on data from the Longitudinal Study of Separated Families (LSSF), which followed up a large sample parents at three post‐separation points, this article examines poverty rates across a 4‐year period, transitions into and out of poverty and factors affecting these pathways.     

基于系统复杂性的决策情景特征及其产生机制

本文从决策方案与决策环境的交互关系角度定义了决策情景的内涵;接着,深入分析了决策情景演化路径的多样性、不确定性、多重尺度集成性、涌现、非均匀分布及对未来的非预测性等性质及其产生机制。这些研究不仅可以使我们更加深刻地认识决策情景,而且能够从系统思维层面为我们提出认知决策情景的新思维。
