Consumer relationship fading

This paper explores the phenomenon of consumer relationship fading with a series of three adjacent studies. Analyzing two longitudinal behavioral datasets, Study 1 shows that about one-third of the relationships could be described as fading. Drawing on prior work in the marriage disaffection literature, Study 2 defines relationship fading for the consumer marketing context as a process of gradual decline in consumers' intention to continue their relationship with a brand, generally manifested in negative feelings toward the brand, diminishing frequency and/or volume of transactions with it, and initiation of switching intentions. It further identifies disillusion, disaffection, and crossroads as three distinct fading stages, and outlines boundary conditions. Study 3 observes relationship fading through a diary study approach and finds attitude movement in both positive and negative directions between the stages. Further, while positive attitudes generally decline over the course of the fading trajectory, negative emotions peak at the penultimate fading stage and then level off at the final, crossroads stage. By defining and analyzing consumer relationship fading, we improve understanding of an under-researched, large segment of consumers.     

兼容性制度竞争:双层对冲与地区制度的嵌套设计北大核心

地区制度的兴起增加了全球治理机制的复杂性。竞争性多边主义理论强调制度竞争会导致国际机制的碎片化和规则冲突。制度聚合理论则认为制度背景会强化规则的一致性,甚至形成制度服从。这种冲突—聚合的二分法不足以分析地区制度与多边制度之间关系的复杂现实。作者提出一个双层对冲的分析框架,以解释地区制度与核心多边制度间的联系机制;一方面,地区成员要通过建立地区制度寻求外部选项,实现对现有多边制度的制衡。另一方面,地区成员又离不开现有多边制度,需要借用现有的多边制度资源来解决地区制度建设中的机会主义问题。为了实现双层对冲,地区成员国会根据地区制度的系统冲击效应和投资报偿结构,设计不同的制度嵌套。作者比较了金融救助领域的欧洲稳定机制、清迈倡议多边化以及拉美储备基金等地区金融安排,其结果符合预期。双层对冲框架下的兼容性制度竞争有利于推动国际制度的渐进变迁,限制了大国在国际秩序转型中的冲突烈度,为世界政治的和平权力转移提供了可能。     

Effects of crisis response tone and spokesperson's gender on employer attractiveness

Timely apologies to key publics on social media are becoming an important aspect of crisis recovery but little is known of how the spokesperson’s characteristics and the tone of apology may influence the outcome. Recognising the importance of the need to attract quality workforce, this study examines the impact of social media response to a preventable crisis on organisational attractiveness. Specifically, a 2 (message tone: corporate/formal vs. human/informal) x 2 (spokesperson’s gender: male vs. female) between-subjects factorial design was used to test the effectiveness of an apology. The results suggest a significant moderated mediation effect. We find that account acceptance mediates the relationship between message tone and organisational attractiveness, and this effect is conditional on gender of the spokesperson. The results are relevant to crisis managers and brand managers that seek to attract and retain talents.     

中国自然保护地规划的回顾与对比研究

中国自然保护地历经60余年的发展，形成了多部门主导、保护类型多样的自然保护地体系。面对机构改革和以国家公园为主体的自然保护地体系建立的契机，传统规划的经验积累为新规划体系的构建提供了借鉴的可能。通过回溯机构改革前各类自然保护地规划，对比分析其规划结构体系，并从人地关系视角切入，分析各类规划针对保护对象、保护利用强度,以及社会发展调控上的差异，总结各类自然保护地规划的既有经验，为新时期规划体系的重构提供支撑。     

The effects of the visual presentation of an Influencer's Extroversion on perceived credibility and purchase intentions—moderated by personality matching with the audience

Influencers are ordinary individuals who have amassed large followings by demonstrating expertise in various niches on social media sites. We aim to propose (1) the visual presentation of an Influencer's extroversion as an antecedent to source credibility and purchase intentions and (2) personality matching in terms of extroversion between an Influencer and their audience as a moderator of such relationships. We chose the source credibility model and the similarity-attraction model as our theoretical frameworks. In our controlled online experiment (n = 165), the profile of a brand ambassador of a fashion brand was curated to create two levels of extroversion (i.e. low vs. high extroversion). Participants' self-reported extroversion levels were counterbalanced in these two conditions to create a personality match with the Influencer, entitled “extroversion congruence.” Our results suggest that the visual presentation of an Influencer's extroversion increases the perceived credibility of the Influencer and subsequent purchase intentions. Additionally, our findings show that these relationships were asymmetrically moderated by extroversion congruence: the positive effects of extroversion increase in the case of high extroversion among both the Influencer and their audience but decrease in the case of low extroversion.

基于信息辅助块稀疏贝叶斯学习的直扩通信窄带干扰抑制

现有基于Nyquist-Shannon采样定理的窄带干扰(Narrowband Interference,NBI)抑制方法存在应用受限于采样率较高的问题。应用压缩感知(Compressive Sensing,CS)理论解决上述问题，利用NBI在频域表现出的块稀疏特性以及直接序列扩频(Direct Sequence Spread Spectrum,DSSS)信号的类噪声特性，提出了基于块稀疏贝叶斯学习(Block Sparse Bayesian Learning,BSBL)框架的DSSS通信NBI抑制模型。实现干扰抑制后，利用传统的CS重构算法实现DSSS信号的压缩域解调。为进一步提高算法性能，将NBI稀疏分块的块内自相关矩阵建模为单位矩阵，提出了信息辅助BSBL(Aid BSBL,ABSBL)算法，设计了基于ABSBL的DSSS通信NBI抑制算法。该算法在保持较好NBI抑制性能的条件下，提高了运算效率并且不依赖NBI的稀疏结构。仿真验证和对比分析结果表明，所提方法能够有效抑制DSSS通信中的NBI，在干扰强度相同的条件下，NBI带宽越小、压缩率越大，算法对NBI的抑制性能越好。     

利用双正交小波变换优化G3-PLC系统性能

为了提高G3-PLC(G3-Power Line Communication)在复杂信道环境下通信的可靠性，提出了基于双正交小波变换的正交频分复用（Discrete Wavelet Transform-Orthogonal Frequency Division Multiplexing,DWT-OFDM）。通过双正交小波变换减小复杂信道环境下G3-PLC通信系统中OFDM载波间干扰，并通过合理减少循环前缀，优化传输效率，降低峰均比。在DWT-OFDM的G3-PLC系统中，通过不同小波基性能分析与对比，利用bior6.8双正交小波基进行系统性能优化。将DWT-OFDM的G3-PLC系统在实际电力线噪声库环境下进行实验分析，仿真结果表明，在平均误码率为10-3量级时，性能有5 dB左右提升，通信效率由40%提高至54%；结合限幅法，峰均比由11 dB降低至8 dB，通信性能极大优于基于FFT-OFDM的G3-PLC系统。     

“一带一路”沿线省域生产性服务业与制造业联动融合关系辨析

选择"一带一路"沿线18个省域生产性服务业与技术或资本密集型装备制造业动态互动关系为研究对象,运用向量自回归(VAR)模型进行4个细分服务业和装备制造业脉冲响应比较研究,探究其双向互促性、行业异质性及长短期差异性。结果表明:二者虽然有长期均衡关系,但是互促作用具有非对称性。装备制造业对生产性服务业发展的总体拉动力强劲。但无论辅助联动式或价值链嵌入式生产性服务,都只是短期助推装备制造业发展,仍难以构成高端服务能力和发挥显著的规模经济效应,其长期匹配及推动作用较小。长期以来,装备制造业对知识密集型服务业需求程度不高,导致装备制造业对其拉动作用不明显,二者互动关联性较弱。不同互动机理及动态匹配方式下细分服务业与装备制造业互动效应差异性显著。装备制造业来自于自身内部的信息变动影响显著。应加强装备制造业创新投资引资、提升装备制造业产业集群创新竞争力、促使生产性服务业高质量发展、提高高层次人才培养引进效率,以促进沿线省域两大产业高层级耦合互动发展。
