Clockwise versus counterclockwise turning bias: Moderation effects of foot traffic and cognitive experience on visual attention

The current research aims to examine how turning bias can affect the attention-capturing of bottom-up factors in endcap displays. In three experimental studies using eye-tracking, this paper contributes to the literature by proposing moderators that shape turning bias effects on retail endcap displays. Studies 1 and 2 demonstrate that consumers' counterclockwise (vs. clockwise) rotation reduces visual attention on endcap displays. Furthermore, Study 3 indicates that longer trips and higher loop diversion increase the number of fixations for clockwise (vs. counterclockwise) turning shoppers. In addition, higher cognitive anchors and shorter shopping lists boost fixation rates when shoppers rotate in a clockwise (vs. counterclockwise) direction. This research has important theoretical and practical implications for understanding shoppers’ visual attention and cognitive experience in retail settings.     

基于心理偏差的金融资产定价模式

金融资产定价一直以来都是金融学的焦点问题,传统的资产定价模型主要基于基本经济层面的影响因素分析,而没有考虑投资者的心理因素。近些年来,行为金融学越来越受到大家的关注,越来越多的研究者将注意力放到投资者的投资心理上,鉴于此,从投资者心理角度出发,研究了投资者在投资过程中认知、情绪、意志过程的偏差对资产定价的影响,并构建了基于心理偏差的金融资产定价理论模式。     

近距离无线电台邻道干扰的功率谱解析

指挥控制系统的无线通信设备数量多、工作频率范围窄，相互之间存在严重的邻道干扰。针对近距离电台间邻道干扰问题，提出了基于功率谱解析的分析方法。首先理论推导了信号原功率谱密度函数与展宽延拓后功率谱密度的严格数学关系，在此基础上研究邻道干扰产生机制，进而分析不同邻道的干扰强度，得到了邻道功率与频率之间的关系式，推导了进入接收机的信干噪比（SINR）；最后，通过仿真验证了所提出的分析方法的可行性。理论计算与仿真结果相差在0.5 dB以内，为进一步有效规划指控系统频谱和提高利用效率提供了重要依据。     

脉冲超宽带测控信号时延精密跟踪方法

脉冲超宽带测控新体制可有效提高测控系统的安全性能，且具有潜在的高精度测距能力。为了实现其高精度测距功能，提出了一种基于延迟锁定环路的脉冲超宽带测控信号时延精密跟踪方法。该方法在传统伪码跟踪环的基础上进行改进，利用基于非相干积分的非线性反馈环路对接收信号的脉冲相位进行精密跟踪。理论分析和仿真结果表明，该延迟锁定环路可以完成对脉冲超宽带测控信号的时延精密跟踪。与直扩测控信号相比，在相同条件下，脉冲超宽带测控信号的时延跟踪相对误差更大，但由于脉冲宽度很窄，在一定载噪比条件下，其测量精度仍可达厘米量级甚至更高。     

认知偏差对农户宅基地退出意愿的影响——基于广东省880个样本农户的实证研究

研究目的：基于前景理论分析认知偏差对农户宅基地退出意愿的影响机理，利用广东省880份调查数据进行实证检验，以期引导农户自愿有偿退出，提升政策实施成效，推进宅基地制度改革。研究方法：问卷调查法、二元Logistic回归模型。研究结果：（1）信息认知偏差以1%的统计水平显著影响退出意愿，回归系数为-1.830，其中负面经验锚定和高价格锚定显著抑制农户退出意愿；（2）群体认知偏差以1%的统计水平显著影响退出意愿，回归系数为-1.336，农户正面从众程度越高，退出意愿越强；（3）功能认知偏差以1%的统计水平显著负向影响退出意愿，回归系数为-0.782，高程度的保障、经济、心理功能感知显著降低农户退出意愿。研究结论：由于存在锚定、从众、禀赋效应，农户在宅基地退出行为决策中易形成信息、群体、功能认知偏差，最终影响其退出意愿。据此，增强农户宅基地退出意愿重点要从削弱负面经验锚定的抑制作用、发挥正面从众心理的促进作用、减轻禀赋效应和高价格锚定的负面影响三方面着手，加强信息化的基层动员宣传力度，发挥正向化的群体规范引导效用，制定多元化的退出补偿标准体系。     

基于UGC的黑井古镇形象感知研究

基于旅游目的地形象感知“认知—情感—整体”三维模型，采用内容分析法，分析游客对黑井古镇的目的地感知形象。结果表明:（1）在认知形象上，游客对黑井古镇的认知形象以场所、文化、自然和活动认知内容维度为主，以建筑认知内容维度为辅。（2）在情感形象上，积极感知主要来源于古镇历史文化悠久，具有研究价值的盐文化和历史文化建筑，是古镇吸引游客的亮点。消极感知主要来源于古镇自身特色不够鲜明、其他文化感知较弱、文化活动单调、基础设施不够完善、路途体验感较差交通不便，卫生差等问题。（3）黑井古镇整体形象共线网络丰富，集群较多，形成了古镇、黑井古镇、建筑、文化、产贡盐、龙川江6个主要集群，语义网络的共线性较强。     

认知选择协同分集任意信噪比中断概率的分析

选择中继已被证明是一种有效和实用的协作分集方法.但是,现有的分析主要集中在渐进高信噪比(SNR)区域,因此,研究认知选择协同分集系统任意信噪比的中断概率具有现实意义.推导了瑞利衰落信道选择中继协议的中断概率解析式,并进行了仿真.仿真结果表明,选择中继协议在任意信噪比情况下,增加中继节点可降低中断概率,而解码中继协议(DF)在低、中信噪比情况下不一定降低中断概率;同时,选择中继协议的中断性能和分集增益随频谱空穴检测能力的提高而增强.     

Stock price synchronicity,cognitive biases,and momentum

The momentum anomaly is widely attributed to investor cognitive biases, but the trigger of cognitive biases is largely unexplored. In this study, inspired by psychology studies linking cognitive biases to the noisiness of information, we examine whether momentum returns are associated with high stock price synchronicity, a manifestation of noisy firm-specific information. Our results demonstrate that momentum is more pronounced in the presence of high stock price synchronicity. This finding is robust to other explanations and firm characteristics. We also find that stock price synchronicity boosts the profitability of momentum by amplifying investor underreaction to new information.     

衍生品交易盈亏披露会影响瞬时股价吗？——基于2020年A股上市公司的分析

对2020年A股上市公司披露信息中含衍生品交易盈亏信息的数据进行多期双重差分分析，发现衍生品信息无论利好还是利空，皆存在显著负面的公告溢价。衍生品披露当日瞬时股价、3～5个交易日窗口期的累计异常收益率显著下跌，且衍生品信息不会显著影响该股票长期价值。细分披露类型发现，定期披露的衍生品信息导致的瞬时股价波动较小，且具有更显著的公告盈余漂移。     

Critical factors characterizing consumers’ intentions to use drones for last-mile delivery: Does delivery risk matter?

Uncrewed Aerial Vehicle (UAV), commonly known as a drone, has become popular in military and recreational circles. Although their usage in commerce is relatively low, a continuous rise in commercial use, especially for last-mile delivery, in the future is anticipated. Consequently, there is a necessity for a greater understanding of consumers' readiness to accept the latest technological application to increase knowledge, business, and managerial practice. Specifically, this study aims to investigate consumers’ intentions to deploy drones for last-mile delivery. The study applies the social cognitive theory and the model of goal-directed behaviour. It investigates the effect of outcome expectancy, lifestyle compatibility, perceived self-efficacy, consumer attitude, and the desire of usage for delivery drones among European millennial consumers. Additionally, it examines whether delivery risk moderates the influence of attitude and desire to use delivery drones. The authors discovered that the aforementioned are positively related to consumer attitude. Consumer attitude as such is positively associated with the desire and intention to use this method of delivery. Furthermore, the intention to use drone delivery is positively influenced by the desire for this delivery, outcome expectancy, and lifestyle compatibility. These findings indicate the importance of desire and lifestyle compatibility as predictors. At the theoretical level, the results support the perspective that social cognitive theory, together with the model of goal-directed behaviour, is an adequate framework to account for consumer intentions.
