A case-based distance method for screening in multiple-criteria decision aid

Screening is a process of multiple-criteria decision aid (MCDA) in which a large set of alternatives is reduced to a smaller set that most likely contains the best choice. We propose screening using a distance model calibrated on the basis of the decision-maker's own judgement. Viewing MCDA as preference aggregation based on consequence data, we define consequence and preference expressions (values and weights) and describe how they are aggregated. Then we define screening and explain some of its properties. Using an appropriate definition of distance, our case-based distance method screens a set of alternatives using criterion weights and a distance threshold obtained by quadratic optimization using the decision-maker's selection of alternatives from a test set. This case-based method can elicit the decision maker's preferences more expeditiously and accurately than direct inquiry. An application in water supply planning is used to demonstrate the procedure.     

企业文化构建中的"两点论"——对绍兴餐饮文化建设的反思

对企业文化建设,既要重视,又要有科学的方法.绍兴餐饮业作了有益尝试,他们在打造诚信、人本、品牌、创新四大经营理念时,从剖析餐饮业及各企业特有的经营关系,运用"两点论",把四大经营理念分别应用到对立统一的各种层面中,取得双赢效果,推动了经营矛盾的解决,拓展了四大经营理念的应用空间.文章在调查了绍兴十家中型宾馆、饭店基础上,对此进行梳理.     

“唯识”与“唯了别”辨析

在《唯识三十颂》的四个译本中vijāna与vijapti及vijaptimātratā的语义与义理有各不相同的内涵，以“唯识”迻译vijaptimātratā，并非玄奘未经考虑的做法，即使以安慧《三十唯识释》（或译《唯识三十论》）来看，也难说就是“误译”，更谈不上由此“误译”而引来的研究唯识的千年“误区”。     

Dynamic Pricing to Minimize Maximum Regret

We consider a dynamic pricing problem that involves selling a given inventory of a single product over a short, two‐period selling season. There is insufficient time to replenish inventory during this season, hence sales are made entirely from inventory. The demand for the product is a stochastic, nonincreasing function of price. We assume interval uncertainty for demand, that is, knowledge of upper and lower bounds but not a probability distribution, with no correlation between the two periods. We minimize the maximum total regret over the two periods that results from the pricing decisions. We consider a dynamic model where the decision maker chooses the price for each period contingent on the remaining inventory at the beginning of the period, and a static model where the decision maker chooses the prices for both periods at the beginning of the first period. Both models can be solved by a polynomial time algorithm that solves systems of linear inequalities. Our computational study demonstrates that the prices generated by both our models are insensitive to errors in estimating the demand intervals. Our dynamic model outperforms our static model and two classical approaches that do not use demand probability distributions, when evaluated by maximum regret, average relative regret, variability, and risk measures. Further, our dynamic model generates a total expected revenue which closely approximates that of a maximum expected revenue approach which requires demand probability distributions.     

公共需求的传递和满足机制研究

政府职能的实现过程就是政府满足公共需求的过程。在公共需求的传递和满足过程中,公共需求由公众传递给其在议会的代理人——议员,再传递给政府,最后由政府以提供公共产品的形式予以满足。但在这一过程中,由于公众、议员(议会)、政府(官僚)所拥有的利益目标不完全相同,而各方都寻求其自身利益的最大化,在这种多重委托——代理关系下,造成公共需求在传递和满足过程中受到扭曲。其中,同质性公共需求与异质性公共需求在传递和满足过程中所受扭曲程度及影响因素各有不同。     

对和谐社会创业中失地农民的社会政策支持研究

如何解决失地农民创业以保障其生存权和发展权问题,使其生计得以持续,关系到和谐社会的构建和新农村建设的成效。本文以景德镇市失地农民创业为例,从当地失地农民创业的现状出发,分析失地农民创业的社会政策存在的问题和不足,在借鉴其他地区失地农民社会政策的基础上,建议从完善政策的制定机制、政策执行机制、丰富社会政策内容、加强对政策执行情况监督四个方面来完善失地农民创业的社会政策。     

紧急避险:对无责任能力人的侵害予以反击之行为的重新界定——从主观违法性论在我国之提倡说起

对无责任能力人之侵害予以反击的行为应当属于紧急避险,因为:在我国的犯罪论体系之下,只有采取主观违法性论才能保持理论的严谨和一贯;紧急避险的对象并非仅限于第三人的合法权益;将反击无责任能力人之侵害的行为定性为紧急避险在理论上更为圆满;行为人在无法知道对方是无责任能力人时所实施的反击属于意外事件型的假想防卫;作为正当防卫对象所必须具备的责任能力并非刑事责任能力,而是民事侵权责任能力。     

消费文化语境下的"媒介文学事件"

20世纪90年代以来,消费文化和作为消费文化支撑的大众传媒迅速发展。在这样的语境下出现了“美女作家群”、“80后”等一系列文学现象。本文提出“媒介文学事件”概念,从理论上找出这类文学现象运作的一般规律。首先通过特征描述的方式来定义这个概念,其次将定义要素转化成一种类型,从语言学的角度来定义它,并进一步认为,“媒介文学事件”与消费文化的内在联系存在于“符号消费”。     

老年慢性阻塞性肺疾病急性加重期患者的临床观察

目的研究老年AECOPD患者的肺通气功能和气道阻力特点以及对β2受体激动剂的反应。方法通过支气管舒张试验,200名老年AECOPD的住院患者被分为支气管舒张试验阳性组和阴性组,后者又随机分为阴性一组和阴性二组,三组均给予基础治疗,阳性组和阴性一组加用β2受体激动剂治疗。治疗前后分别行普通肺功能及IOS检查。结果治疗后阳性组和阴性一组的各指标均有改善(P<0.05),阴性二组的MEF50,MEF75,X5,R5,Z5改善不明显(P>0.05),MEF25,R20,FEV1,FVC,Fres有改善(P<0.05)。阴性二组与阴性一组相比发现FEV1,FVC,MEF75,R20等差异不显著(P>0.05),MEF25,MEF50有明显减低(P<0.05),Fres,R20,X5,R5,Z5等明显增高(P<0.05)。治疗后的阴性一组与阳性组比较,FEV1,FVC,MEF25,MEF50,MEF75等有降低(P<0.05),Fres,R20,X5,R5,Z5均明显升高(P<0.05)。结论支气管舒张试验阳性的老年AECOPD患者对β2受体激动剂更敏感,而支气管舒张试验阴性的老年AECOPD患者也有效,但改善相对较小。
