Die Geld-zur��ck-Garantie �C Mehr als nur ein Qualit?tsindikator?

Money-back guarantees have become an increasingly popular tool for marketing managers??mainly because they are regarded as an effective means to signal product quality. However, from an academic perspective there is sparse empirical evidence on whether such a signaling effect really exists and, most importantly, whether it influences consumer decision making. Hence, the objective of the paper is to empirically analyze the consequences of money-back guarantees on consumer buying behavior in a holistic theoretical framework accounting for both cognitive and affective consumer responses. Our results reveal that the existence of the rather cognitively driven signaling effect of a money-back guarantee is contingent on several factors: Besides the type of the product (search versus experience good), it particularly depends on consumer knowledge as well as on whether a money-back guarantee is offered for a strong or for a rather weak brand. In addition, we show that a money-back guarantee also induces affective consumer responses which additionally contribute to consumer buying behavior. These responses are mainly due to the guarantee??s insurance function reducing consumer uncertainty about product features.

宋代河北书院述论

对于宋代河北书院的研究,从以往的3所扩充到5所,并对5所书院的发展进行了分析,总结了书院师生体现出来的理学家教育理念及方法.对比全国其他区域书院发展的状况,宋代河北的书院发展相对薄弱,与古代后期相较相对滞后,究其原因是战争的影响、行政建制问题以及河北地区遭受的蝗灾、洪灾等方面的影响造成的.     

Control charts for fraction nonconforming in a bivariate binomial process

Many multivariate quality control techniques are used for multivariate variable processes, but few work for multivariate attribute processes. To monitor multivariate attributes, controlling the false alarms (type I errors) and considering the correlation between attributes are two important issues. By taking into account these two issues, a new control chart is presented to monitor a bivariate binomial process. An example is illustrated for the proposed method. To evaluate the performance of the proposed method, a simulation study is conducted to compare the results with those using both the multivariate np chart and skewness reduction approaches. The results show that the correlation is taken into account in the designed chart and the overall false alarm is controlled at the nominal value. Moreover, the process shift can be quickly detected and the variable that is responsible for a signal can be determined.     

Pareto efficiency in multiple referendum

We consider situations of multiple referendum: finitely many yes-or-no issues have to be socially assessed from a set of approval ballots, where voters approve as many issues as they want. Each approval ballot is extended to a complete preorder over the set of outcomes by means of a preference extension. We characterize, under a mild richness condition, the largest domain of top-consistent and separable preference extensions for which issue-wise majority voting is Pareto efficient, i.e., always yields out a Pareto-optimal outcome. Top-consistency means that voters’ ballots are their unique most preferred outcome. It appears that the size of this domain becomes negligible relative to the size of the full domain as the number of issues increases.     

Attribute Control Chart for Multivariate Poisson Distribution

In this study, a control chart is constructed to monitor multivariate Poisson count data, called the MP chart. The control limits of the MP chart are developed by an exact probability method based on the sum of defects or non conformities for each quality characteristic. Numerical examples are used to illustrate the MP chart. The MP chart is evaluated by the average run length (ARL) in simulation. The result indicates that the MP chart is more appropriate than the Shewhart-type control chart when the correlation between variables exists.

地位焦虑、物质主义与炫耀性消费——中国人物质主义倾向的现状、前因及后果

通过对369份有效样本的层级回归进行实证检验,结果显示:中国人确实存在较高的物质主义倾向,且在人口统计因素上存在差异,其中男性比女性具有更高的物质主义倾向;家庭收入越高,物质主义倾向也越高;不同教育程度和年龄对物质主义倾向的影响不够显著.在中国社会转型背景下,人们的地位焦虑与物质主义倾向显著正相关;物质主义倾向与中国人的炫耀性消费显著正相关;物质主义倾向在地位焦虑与炫耀性消费之间起着中介作用.
