Generally weighted moving average control charts with fast initial response features

The generally weighted moving average (GWMA) control chart is an extension model of exponentially weighted moving average (EWMA) control chart. Recently, some approaches have been proposed to modify EWMA charts with fast initial response (FIR) features. We introduce these approaches in GWMA-type charts. Via simulation, various control schemes are designed and then their average run lengths are computed and compared. Based on the overall performance, it is showed that the DGWMA chart is the best choice especially when the shift is moderate, and the GWMA charts provided with additional FIR feature have a good performance only in detecting large shifts during the initial stage.

新经济时代的地方法治环境研究——以武汉和重庆为例

随着第三次工业革命的兴起,以信息技术和市场创新为核心要素的新经济浪潮已经到来。在新经济时代,法律能够整合社会资源,协调利益冲突,激励创新活力,促进科学技术的高效运用。以武汉和重庆为例,随着新的社会关系和利益冲突的不断出现,不少地方立法的内容难以适应科技发展的新形势,执法、司法等领域面临着新经济带来的多重挑战。优化地方法治环境,应按照“效益优先、依法治理、政府主导、公平竞争”的原则,在地方科技法制工作中加大促进科技成果转化和技术转移力度,增强企业的可持续创新力和市场竞争力,依法建构多元化的科技投入机制和财政供给机制,提升政府科技管理和知识产权保护水平,营造公正和谐的地方司法环境。

《欲望号街车》的两个电影版本对原著的创作内涵做了截然不同的诠释。从比较两个电影版本改编的逻辑性入手,应用接受美学理论、知觉概念,对文本的叙述结构、人物性格及心理特征进行了分析,从而解构作品的两重性,从一个新的视点展示了成就这部伟大作品的原因。     

辽宁装备制造业利润波动性的协整VEC模型分析

通过建立VAR模型,运用脉冲响应函数和预测方差分解的方法对辽宁省装备制造业利润增长的波动情况进行实证分析。研究结论：无论长期还是短期出口对辽宁装备制造业利润的贡献都不大,辽宁装备制造业发展与出口导向型经济增长假说不相符,而与经济增长导致出口扩张假说（GLE）相符。表明振兴辽宁装备制造业不能仅依靠出口,关键在于产品技术和组织形式的创新。     

Structural and Behavioural Changes in the Short TermPreventive Check in the Northwest Balkans in the 18th and19th Centuries

Fertility responded negatively to grain insufficiency(proxied by grain price increases), and mortality respondedpositively in Croatia-Slavonia-Srem in the 18thand 19th centuries, as in most of Europe. Shiftsin the intensity and timing of these responsesoccurred over time as social and economic structureschanged. Shifts in the elasticity of fertility withrespect to grain supply inversely mimic and lagchanges in the elasticity of mortality. Both appear tobe induced by increasing land shortage, the collapseof feudalism, and differences in the patterns ofadjustment to post-feudal conditions among former civiland military serfs. Generally, responses are strongerfor civil and former civil serfs, who may have been inless favourable economic circumstances than themilitary. Fertility responses in the year of a priceshock come to dominate those in the year following,suggesting a shift from contraception to abortion aseconomic and social conditions apparently worsened andstrategies of control intensified. Analysis of monthlyresponses supports the conjecture based on the annualresponses. The shift to the preventive check and strength of thepreventive check in the same year as the price shockis unusual in Europe and beyond. Analysis is based on25 parishes and employs lagged annual and monthly timeseries analysis with corrections for autocorrelation,in combination with ethnographic and historical data.     

后危机时代“弃企逃债”的反思与应对

国际金融危机暴发后,不少地方不同程度出现“弃企逃债”现象并产生一定不良后果。究其原因,既有一些企业及企业主破产心理变态、破产理念失当问题,也有破产生态不良、破产制度硬伤问题。为此,后危机时代应疏导破产心理、确立正确破产观、改善破产生态环境、完善破产法律制度,最大限度、地避免“弃企逃债”,以维护经济秩序,减少社会震动。
