基于Bayes判别法的脑电图数据分析的研究

目的:本文通过对客观记录的受试者脑电图数据进行Bayes判别分析,判断其能否应用于脑电数据特征提取和分类决策。为脑电图研究的其它分析做基础分析。方法:根据α波的强弱不同将21导电极分为四类,分别对63例正常状态下受试者21导联电极的脑电图数据进行Bayes判别分析,并利用误判率回代估计法检验判别准确率。数据处理和统计分析采用独立设计的脑电图分析工具箱和Bayes判别分析程序。结果:表明对63例正常状态下受试者的脑电图数据进行Bayes判别分析,预测各电极分类准确率75.4%。结论:Bayes判别法预测准确率较高,脑电特征(主要为α波)提取较为准确,能较好的应用于脑电数据特征提取和分类决策中,从而辅助脑电图的检查和定量分析,为脑电图的检验提供有效的分析手段。     

Online Price Search: Impact of Price Comparison Sites on Offline Price Evaluations

Consumers increasingly rely on Internet price comparison sites (PCS) to gain knowledge about the market. The prices generated by a PCS search can act as contextual reference prices and influence the attractiveness of prices encountered later as consumers shop offline at local stores. This paper demonstrates that both PCS retailer ratings and the shape of the PCS price distribution influence the impact of PCS search results on later price evaluations. A favorable PCS retailer rating increases the perceived validity of the price associated with that retailer, enhancing the impact of that PCS price on offline price evaluations (Study 1). The shape of the PCS price distribution can also influence later price evaluations, however this effect depends on the information provided by the PCS retailer ratings. When PCS retailer ratings are similar, implying similar validity for the associated prices, low PCS prices and those appearing more frequently in the PCS price distribution have more impact (Studies 2 and 3). When PCS retailer ratings are variable (some high and some low), the PCS price distribution effect occurs only when the PCS retailer ratings provide congruent information about price validity — that is, the most frequent price is offered by retailers with more favorable ratings. Study 3 shows that price validity inferences do mediate this result. Finally, we depart from the offline shopping context to show that when consumers choose a retailer directly from the PCS search results, the effect of PCS retailer ratings is stronger for high-priced retailers and for consumers who rely less on the retailer price as a heuristic to infer retailer service level. Based on our findings we offer insights for online and offline retailers when considering strategic responses, such as price matching guarantees.     

Experimental analysis of choice

Experimental choice analysis continues to attract academic and applied attention. We review what is known about the design, conduct, analysis, and use of data from choice experiments, and indicate gaps in current knowledge that should be addressed in future research. Design strategies consistent with probabilistic models of choice process and the parallels between choice experiments and real markets are considered. Additionally, we address the issues of reliability and validity. Progress has been made in accounting for differences in reliability, but more research is needed to determine which experiments and response procedures will consistently produce more reliable data for various problems.Sawtooth SoftwareDecision Research     

营销情境中的心理契约及其测量

心理契约发轫于组织行为学研究，但心理契约在企业与顾客的营销情境中同样存在。在文献回顾基础上，本文将心理契约应用到营销情境中，界定了特定的概念内涵，开发设计了相应的测度量表，并通过调查数据分析，对量表的信度与效度进行了实证检验。

Validating new product creativity in the eastern context of Malaysia

This paper examines the etic vs. emic nature of the new product creativity (NPC) construct often used in the strategic marketing and management literatures. The current study compares the NPC measure developed by Im and Workman (2004) in the West in an Eastern context by utilizing data from 172 Malaysian companies. The results show that NPC, which is the combination of new product (NP) novelty and NP meaningfulness, has a different connotation in Malaysia. The findings demonstrate that from the novelty perspective NPC is an emic phenomenon. After the construct validation process, the Western claim that NPC is a seed of firm performance is tested. The results verify NPC's relationship with NP performance as a source of competitive advantage for Malaysian firms and thus suggest that this relationship is etic in nature. These findings have significant implications for firms' global innovation strategies.     

Are we overconfident in executive overconfidence research? An examination of the convergent and content validity of extant unobtrusive measures

Building understanding of overconfident executives is central to a growing literature that spans a number of disciplines. Much of this research has utilized unobtrusive, or indirect, measures to assess executive overconfidence from secondary data sources. We analyze the convergent and content validity of seven extant unobtrusive measures of executive overconfidence. The results of our analyses indicate that these measures do not exhibit adequate convergence, suggesting that existing measures are not measuring the same construct. Further, we administer a sort task to academic colleagues to assess whether scholars believe that the seven measures are adequately assessing the intended construct. The results of our sort task indicate that scholars did not categorize any of the seven measures as sufficient for measuring overconfidence. We conclude with suggestions for future research to address the inadequate convergent and content validity found in our assessment of extant measures of executive overconfidence.     

实施转融通制度提高了我国证券市场质量吗？——运用双重差分模型对沪深股市的实证分析

以50种纳入转融通标的证券的股票构造处理组,以50种纳入融资融券标的证券但未纳入转融通标的证券的股票构造控制组,利用转融通制度实施前后各10个交易月份的数据,采用双重差分模型研究转融通制度的实施对证券市场流动性、波动性、有效性等市场质量的净影响,得到的可靠结论是：转融通制度在一定程度上提高了证券市场的流动性,显著抑制了证券市场的波动性,显著提高了证券市场的有效性,总体上改善了证券市场质量。监管者应进一步拓宽转融通标的证券的范围,增加转融通标的证券的数量,并对证券进入转融通标的证券之前和之后进行区别对待;交易者在确定交易策略时也应做出正确选择。
