Risk Perception and Information Processing: The Development and Validation of a Questionnaire to Assess Self‐Reported Information Processing

The role of information processing in understanding people's responses to risk information has recently received substantial attention. One limitation of this research concerns the unavailability of a validated questionnaire of information processing. This article presents two studies in which we describe the development and validation of the Information‐Processing Questionnaire to meet that need. Study 1 describes the development and initial validation of the questionnaire. Participants were randomized to either a systematic processing or a heuristic processing condition after which they completed a manipulation check and the initial 15‐item questionnaire and again two weeks later. The questionnaire was subjected to factor reliability and validity analyses on both measurement times for purposes of cross‐validation of the results. A two‐factor solution was observed representing a systematic processing and a heuristic processing subscale. The resulting scale showed good reliability and validity, with the systematic condition scoring significantly higher on the systematic subscale and the heuristic processing condition significantly higher on the heuristic subscale. Study 2 sought to further validate the questionnaire in a field study. Results of the second study corresponded with those of Study 1 and provided further evidence of the validity of the Information‐Processing Questionnaire. The availability of this information‐processing scale will be a valuable asset for future research and may provide researchers with new research opportunities.     

The effect of cognitive diversity on the illusion of control bias in strategic decisions: An experimental investigation

By integrating cognitive diversity into debiasing literature, this paper contributes towards opening the black box of executive judgment. Based on information processing theory we investigate the role of cognitive diversity in strategic decision making. We apply a vignette-based experimental research design to examine the effect of cognitive diversity in teams on decision maker's illusion of control. The results of these experiments provide evidence for a positive influence of high cognitive diversity for debiasing judgment while similarly indicating no such effect for groups with low cognitive diversity. These findings suggest that group composition aspects can play an important role for improving judgment in decision making teams and open promising new avenues for studying debiasing in behavioral strategy research.     

Dimension reduction via local rank regression

Outer product of gradients (OPG) achieves dimension reduction via estimating the gradients of the regression function. In this paper, we propose two novel OPG estimators via local rank regression: the rank OPG estimator and the Walsh-average OPG estimator. Both proposals guard against a wide range of error distributions, and are safe alternatives to existing OPG estimators based on local linear regression or local L1 regression. The effectiveness of the new proposals are demonstrated via extensive numerical studies.     

我国企业品牌定位的五层次研究

近年来中国企业的品牌建设取得了可喜的成绩,出现了许多优秀品牌,这些品牌凭借独特、合适的定位取得了成功。但企业在品牌定位方面存在许多误区,如把品牌定位看作产品定位、品牌定位模糊,缺乏差异性和明确的核心价值、品牌盲目延伸导致定位混淆等问题。因此,产品品牌定位必须树立正确的定位理念,应用正确的品牌定位方法。正确的品牌定位方法可分为产品特征定位、物质利益定位、情感利益定位、个性定位以及价值观定位共五个层次。     

基于供应链集成的网络式新产品开发研究

基于供应链集成的网络式新产品开发，不是从一个企业或企业集团层面看，而是从整个产业的层面看，那就是新产品开发是由产业内价值链相关各企业及企业外部研发资源，利用企业间的互动机制，相互创意激发及技术交流而产生新产品的一种模式，这种模式的最大优势是全体参与者的共同参与，发挥全体参与者团体作用的优势，强调产品开发流程，以产出为衡量基准，强调“产出成本效率”的业绩评估体系以及通过对外部资源的充分利用，强调“资源优化和无缝对接”和有效配套管理。     

On the existence of linear trend free block designs

We present a class of counerexamples for a conjecture on the existence or linear trend free block designs we will also prove a considerably weakened version of this conjecture which will determine all combinations of designs parmetres for which the class of linear trend free block designs is non empty.     

略述古代赫哲族木制品的类型、特点及成因

在陶瓷器、铁器没有进入赫哲地区前,赫哲族人曾以树木为材料,制作了一件件简单实用、贴近生活的木制生产用具和生活器皿,这些充满浓郁地域特色和民族风格的木制品,为研究赫哲族的古代文化提供了极其丰富的民族学资料。本文试就古代赫哲族木制品的类型、特点及成因等进行粗浅考述,以期对赫哲族的文化研究提供参考。     

不同性质汉语隐喻句认知加工的fMRI研究

有关隐喻认知研究的一个核心问题是:隐喻加工机制与一般言语理解相比是否具有独特性以及隐喻理解伴随的神经生理机制是否有其独特的模式? 对此问题的回答需要对隐喻性质进行区分。常见的熟悉隐喻可进一步区分为词源性隐喻与引发性隐喻,其中词源性隐喻的隐喻义属于词语多个词义中的一个延伸义,而引发性隐喻则是将两个分属于不同概念领域的概念进行非字面的语义联结。词源性隐喻句和引发性隐喻句的理解包含了与一般语义句理解不同的加工内容。相比一般句,词源性隐喻句特异性地激活了与语义竞争相关的左侧颞中回、颞上回以及与加工深度有关的额下回,而引发性隐喻句则在左侧额下回有更多激活。隐喻的内在加工过程和神经机制并不单一,探讨隐喻理解与一般语义理解的异同需要考虑具体的隐喻性质。     

证券分析师性别、盈余预测偏差与纠偏能力

证券分析师个人特征是其能力的重要表征.文章选取2007-2014年我国资本市场相关数据,研究了证券分析师的性别对盈余预测偏差的影响,以及盈余预测偏差的时间序列特征,实证结果显示:第一,整体上男性分析师的盈余预测偏差大于女性分析师;第二,男性分析师对于盈余预测偏差的纠正能力高于女性分析师;第三,随着对公司跟踪时间的增加,男性分析师的盈余预测偏差下降速度更快.研究结果说明,对于分析师跟踪时间较短的公司,女性分析师的盈余预测偏差较小,而对于受分析师长期跟踪的公司,男性分析师的盈余预测结果更准确.研究结论对投资者依据分析师性别判定其盈利预测准确性具有重要意义.     

论我国木材经营加工许可制度改革

木材经营加工产业是一项古老的产业,也是现代林业产业体系中的重要产业,具有极大的发展空间。当前,中国木材经营加工产业发展面临诸多的制度瓶颈,林业行政部门在实施木材经营加工许可制度时存在扩大管制地理空间、压缩木材经营加工企业市场空间、随意设定行政许可有效期和年检等问题。要发展木材经营加工产业,最优选择是取消木材经营加工许可制度,次优选择是全面规范木材经营加工许可制度,包括严格控制地理空间范围、简化木材经营加工许可申请材料、取消年检等。
