Intertemporal choice under timing risk: An experimental approach

This paper investigates how individuals evaluate delayed outcomes with risky realization times. Under the discounted expected utility (DEU) model, such evaluations depend only on intertemporal preferences. We obtain several testable hypotheses using the DEU model as a benchmark and test these hypotheses in three experiments. In general, our results show that the DEU model is a poor predictor of intertemporal choice behavior under timing risk. We found that individuals are averse to timing risk and that they evaluate timing lotteries in a rank-dependent fashion. The main driver of timing risk aversion is nothing but probabilistic risk aversion that stems from the nonlinear treatment of probabilities.

试论辛亥滦州兵谏与立宪派之关系

同盟会建立后,许多革命党人潜入北方,为实现孙中山先生的“首都革命”而积极活动,1911年10月,清王朝在永平进行大规模军事演习,史称“永平秋操”,打入新军的革命党人第二十镇统制张绍曾,第六镇统制吴禄贞,第二混成协协统蓝天蔚秘密商定,借用秋操机会发动武装革命,一举消灭清禁卫军,攻占北京。可是在秋操的前一天夜里,武昌起义爆发,清政府惊惶失措停止了秋操。派荫昌率参加秋操的部分军队南下镇压武昌起义,张绍曾拥军抗命,拒绝南下镇压起义,发动以逼迫清王朝实行立宪为旗号的兵谏,此次兵谏是有预谋,有组织,有明确目标的革命行动,在兵谏期间与京津地区的立宪派有联系,本文对兵谏过程及其与立宪派关系进行了系统论述。     

不同添加剂预混料对哺乳仔猪生产性能的影响

以窝为单位将 70窝哺乳仔猪随机分为 7组 ,设 1个对照组 (试验I组 ) ,6个试验组。试验组分别添加 2 0 0mg/kg派富 (含芽胞杆菌等复合微生态制剂 ) (Ⅱ )、1%的甲酸吡啶铬 2 0 0mg/kg(Ⅲ )、2 0mg/kg泰乐菌素 (Ⅳ )、1%中药免疫增强剂 (黄芪、远智等复合中草药 ) (Ⅴ )、1%的益康XP(酵母培养物 ) (Ⅵ )以及 2 0mg/kg的硝呋烯宗 (Ⅶ )。经过 15d的试验 ,其结果表明 :试验组较对照组提高日增重 11.37% - 34.12 % ,其中Ⅴ、Ⅵ组达到显著水平 (p <0 .0 5 ) ;提高采食量 1.5 9% - 12 .30 % ;降低饲料增重比 8.4 % - 2 0 .2 0 % ;降低仔猪腹泻频次 10 .34- 31.0 3%。经无菌粪样检验 ,试验各组大肠杆菌、沙门氏菌、葡萄球菌数均低于对照组 ,差异不显著 (p >0 .0 5 ) ;而乳酸杆菌、双岐杆菌均高于对照组 ,差异不显著 (p >0 .0 5 )。经部分血液指标分析 ,试验各组的血液各项理化指标均在正常范围内 ,且各组间差异不显著 (p >0 .0 5 )。

Beheimatungsprozesse begleiten — ein Werkstattbericht

Supporting processes of belonging in supervision and coachingThe contemporary employee has to cope with frequent changes. Not only does he lose his familiar environment, he also has to find ways to familiarize himself with new places and to develop a fresh sense of belonging. This process can be understood and facilitated by interpreting the German concept of “Heimat“ as something we have to create ourselves. First experiences demonstrate the usefulness of this approach in coaching processes.     

Expected sample moments of concomitants of selected order statistics

In this paper, the task of determining expected values of sample moments, where the sample members have been selected based on noisy information, is considered. This task is a recurring problem in the theory of evolution strategies. Exact expressions for expected values of sums of products of concomitants of selected order statistics are derived. Then, using Edgeworth and Cornish-Fisher approximations, explicit results that depend on coefficients that can be determined numerically are obtained. While the results are exact only for normal populations, it is shown experimentally that including skewness and kurtosis in the calculations can yield greatly improved results for other distributions.
