On Bartlett correction of empirical likelihood for regularly spaced spatial data

Bartlett correction constitutes one of the attractive features of empirical likelihood because it enables the construction of confidence regions for parameters with improved coverage probabilities. We study the Bartlett correction of spatial frequency domain empirical likelihood (SFDEL) based on general spectral estimating functions for regularly spaced spatial data. This general formulation can be applied to testing and estimation problems in spatial analysis, for example testing covariance isotropy, testing covariance separability as well as estimating the parameters of spatial covariance models. We show that the SFDEL is Bartlett correctable. In particular, the improvement in coverage accuracies of the Bartlett‐corrected confidence regions depends on the underlying spatial structures.

Leader negative feedback-seeking and leader effectiveness in leader-subordinate relationships: The paradoxical role of subordinate expertise

From a motivational perspective of feedback-seeking behavior, we examined the mediating role of leaders' negative feedback-seeking from subordinates in the relationship between the quality of leader-member exchange (LMX) and subordinates' evaluation of leader effectiveness, along with the moderating role of subordinate expertise in the mediated relationship. Using 151 unique matched sets of leader and subordinate reports obtained from 5 large Korean companies, we found that the positive relationship between LMX and leader effectiveness was mediated by leaders' negative feedback-seeking. Additionally, the positive relationship between LMX and leader negative feedback-seeking was stronger when perceived subordinate expertise was lower. Lastly, the indirect effect of LMX on leader effectiveness through leader negative feedback-seeking was stronger when perceived subordinate expertise was lower. These findings were obtained after controlling for leaders' power distance and goal orientations that might influence their motives to seek or avoid feedback. Theoretical and practical implications are discussed.     

Defender–Attacker Games with Asymmetric Player Utilities

The presence of strategic attackers has become an important factor in the security and protection of systems, especially since the 9/11/2001 attacks, and considerable efforts have been dedicated to its study. When defending against the strategic attacker, many existing studies assume that the attacker would seek to minimize the defender's utility, which implies that the defender and attacker have symmetric utilities. However, the attacker's objective is determined by its own valuation of the system and target of the attack, which is not necessarily consistent with the defender's utility. If the attacker unexpectedly targets a different utility, then the defense strategy might no longer be optimal. In particular, the defense strategy could be inferior if the attacker's utility is not known to the defender. This study considers a situation where the defender's utility is the system survivability and the attacker's utility is the expected number of destroyed elements in the system. We investigate possible attack strategies under these two different utilities and compare (a) the conservative defense strategy when the attack utility is unknown to the defender with (b) the optimal defense strategy when the attack utility is known to the defender. We show that the conservative protection strategy is still optimal under asymmetric utilities when the contest intensity is smaller than one.     

京津冀城市圈公共服务供给水平测度及其区域差异分析

京津冀公共服务一体化是突破京津冀发展瓶颈,推动京津冀区域协同发展的重要抓手之一。本文以京津冀城市圈13个城市为研究区域,通过构建公共服务供给水平的评价指标体系,利用熵值法测度了2014-2017年京津冀城市圈各城市的公共服务供给水平,并对其呈现出的区域格局及区域差异进行探讨,结果显示:京津冀城市圈不同城市间公共服务供给水平差异显著,呈现出以北京和天津为中心逐渐衰减的空间格局;2014-2017年京津冀城市圈不同城市间公共服务供给水平的区域差异逐渐缩小,公共服务供给水平由不均衡格局逐渐向均衡格局演进。本文研究结果为推进京津冀城市圈公共服务协调发展提供建议参考。     

试论社会治理背景下政府与市场关系的经济法规制

政府与市场的关系问题是经济法规制的基于问题，如何正确看待政府与市场在经济生态系统内各自的功能及作用，是经济法规制的核心问题。因为这样的认识直接导致了经济立法的体系构建与内容规则。经济法规制是国家实施经济治理与尊重市场调节的基本依据，也是施行经济法治与社会治理的根本前提。所以，从社会治理的背景下来讨论经济法规制的社会经济发展的制度条件及制度生成条件，有利于真正建立和完善经济法规制的体系和内容，从而使得经济法治生态化地融入社会治理的结构体系内，达到优化社会制度以促进经济发展的目的。     

China’s Demographic Future Under the New Two-Child Policy

China implemented the two-child policy in 2016, however, potential impacts of this new policy on its population reality have not been adequately understood. Using population census data and 1% population sampling data during the period of 1982–2015, this study develops a fertility simulation model to explore the effects of the two-child policy on women’s total fertility rate, and employs Cohort Component Method in population projections to examine China’s demographic future with different fertility regimes. The fertility simulation results reveal that the two-child policy will make significantly positive effects on China’s total fertility rate through increasing second births, leading to a sharp but temporary increase in the first 5 years after the implementation of the new policy. In addition, population projections using simulated total fertility rates show that the Chinese population would reach its peak value around the middle 2020s and be faced with the reduction of labor force supply and rapid aging process, featured with remarkable increases in both size and share of the elderly population. The findings suggest that the two-child policy would undoubtedly affect China’s fertility rates and demographic future; however, the effects are mild and temporary.

     

川东北地区须家河组二段储层差异性分析

随着勘探程度的深入，为了扩大四川盆地天然气勘探领域、寻找新的勘探接替区，四川盆地的勘探区域由盆内逐渐向盆缘延伸。在这种背景下，川东北地区须家河组二段相继取得新的勘探成果，但在勘探开发过程中逐渐暴露了诸如区块之间气井产能差异大，储层的碎屑组分、结构及厚度、物性、孔隙结构差异明显等问题，制约了勘探开发的步伐。针对上述问题，根据岩芯观察描述、分析化验资料及测井解释成果，从沉积、成岩方面入手，对比剖析了川东北龙岗和营山地区须二段储层特征的差异性及其成因，认为远离物源区和高能水体的反复淘洗是造成储层差异性的首要因素，强烈的压实作用和多期石英加大对储层差异性起关键作用，自生绿泥石衬边胶结和长石选择性溶蚀最终决定了储层差异性。从而解释了气藏勘探开发中遇到的诸多问题，对有效指导该区的下一步勘探开发工作具有重要意义。

中国留英博士毕业生的社会流动

近年来,中国高等教育国际化的脚步越来越快,出国留学和留学归国人数逐年增长。基于一手访谈数据,探究海外博士教育是否能带给海归博士带来预期的职业发展和社会流动,并分析出海归博士归国工作后的社会流动到底呈现出什么样的特征。深入地研究了海归博士的社会流动的影响因素以及国家留学基金委奖学金在其中的作用。研究发现,海归博士的社会流动性比较小,大部分的海归博士都守住了原有的中产阶级社会地位,并没有取得很明显的向上流动;关于社会流动的影响因素,奖学金和家庭背景在博士海归归国后的社会流动中扮演重要角色。
