论《天边外》三位主人公的心理悲剧

研究指出,多幕剧《天边外》是美国剧作家尤金·奥尼尔的成名作,从这部剧开始,奥尼尔进入创作的成熟期,他在美国戏剧界的地位也是由这部剧确立起来的。《天边外》在探索人物内心焦灼挣扎方面得到普遍的承认。本文将通过对其中三位主人公安德鲁、罗伯特、露斯的心理的分析,探索欲望的控制对人物命运的毁灭性打击。     

井眼倾斜角和倾斜方位对裸眼完井地层出砂的影响

结合等效塑性应变准则定量地研究了井眼倾斜角和倾斜方位对裸眼完井砂岩油藏出砂的影响。计算结果表明,在一定的应力和地层条件下,井斜角在0~45°时,随着井斜角的增加,井壁内的塑性应变最大值和塑性区范围都不断增加,出砂的趋势增大;当井斜角在45°~90°时,随着井斜角的增加,井眼内最大塑性应变逐渐减小,出砂趋势减小。井斜角相同,但井眼倾斜方位不同的井,井壁内产生塑性变形的区域不同,塑性变形的程度也不同,从防砂的角度,井眼,尤其水平井眼应该沿原地最小水平主应力方向,或尽可能靠近最小主应力方向。     

非再生性资源的价格路径问题研究

文章内对现有的非再生性资源的最优价格路径问题的文献进行了整合性研究，解释了在短期内非再生性资源的价格路径呈U型原因。并进一步从产权制度的不确定性和供需双方的战略性的博弈行为两个角度对价格路径进行了拓展。在霍特林规则失灵的情况下，资源配置可能与社会最优相偏离，也可能不会。针对市场失灵，提出了相应的政策建议。     

Beyond the CPI: An Augmented Cost-of-Living Index

This note examines an augmented cost-of-living index (ACOLI) for the purpose of accounting for “augmented consumption” in real-income measures. Well-being includes not only conventional consumer purchases but also goods and services provided by employers, by mandated social regulations, and by tax-financed public goods. Because augmented consumption is often provided in ways that raise prices but not market incomes, deflating with conventional price indexes may understate real income growth. An exploratory application of the ACOLI approach to the United States during the 1960–1997 period suggests that the Consumer Price Index has grown about 19% faster than the ACOLI. This correction would reduce the estimated cost-of-living increase by .47% per year over the last 37 years.     

EGARCH Model with Weighted Liquidity

We analyze a variant of the EGARCH model which captures the variation of the intra-day price. We study the asymptotic behavior of the estimators for the parameters of the model. We also illustrate our theoretical results by empirical studies.     

果业财政补贴与激励机制设计

果业发展的关键在于技术和品种的更新,而引入新技术需要投入较多资金,更新品种也要几年后才有收益,这制约了广大果农对果业升级换代的积极性,影响了果业的发展。因此,政府应对果业提供产出补贴与品种更新补贴,以此来激励果农采用新技术及新优果树品种,提高果业的竞争力。政府的具体补贴数额可通过补贴激励机制模型计算得出。     

On the improvement of one-sided S control charts

The most common charting procedure used for monitoring the variance of the distribution of a quality characteristic is the S control chart. As a Shewhart-type control chart, it is relatively insensitive in the quick detection of small and moderate shifts in process variance. The performance of the S chart can be improved by supplementing it with runs rules or by varying the sample size and the sampling interval. In this work, we introduce and study one-sided adaptive S control charts, supplemented or not with one powerful runs rule, for detecting increases or decreases in process variation. The properties of the proposed control schemes are obtained by using a Markov chain approach. Furthermore, a practical guidance for the choice of the most suitable control scheme is also provided.     

社会认知偏差:群体性事件生成的社会心理启动根源

社会认知偏差是群体性事件生成的深层次社会心理现象,通过对山东部分地区进行抽样调查,并结合近几年来全国群体性事件典型案例的分析发现,生成群体性事件的社会认知偏差,主要包括事件诱因责任归因偏差、行为模式结果预期偏差和行为结果价值偏差。因此,改善法的实施现状,消除社会认知偏差;提高公众法律意识,优化社会认知;建立心理危机干预队伍,合理引导社会认知,是群体性事件社会认知偏差的有效干预对策。     

青年领导干部要增强宪法意识纪念1982年宪法实施20周年

目前,青年领导干部中表现出来的宪法意识偏差主要表现为轻视宪法学习、缺乏宪法信仰;忽视宪法特性,降低宪法地位.相伴而生的主要违宪行为即是违背宪法精神、超限行使权力;违反宪法规定,侵犯公民权利.因此,必须要以有计划的培训考核;推动青年领导干部学习"三个代表"思想与宪法精神的一致性、学习宪法条款;强化人民民主与权利观念;以转变领导方式和工作方法去落实依法行政;发挥学习、遵守、使用宪法的表率作用.     

我国丝绸出口贸易的经济分析

我国丝绸出口贸易的 "显示"比较优势指数呈逐年下降的趋势,但其数值一直保持在17以上,说明我国的丝绸出口与其他出口商品相比仍具有很大的竞争优势;我国丝绸出口的相对价格弹性系数为-0.3825,属于低弹性的商品.降低丝绸出口价格,不但无益于丝绸出口量的增加,反而会引起出口创汇额的明显下降,引起丝绸"出口贫困"现象的产生.稳定我国丝绸出口价格,是我国蚕丝业和丝绸贸易稳定发展的正确选择.
