Impact of auditory sense on trust and brand affect through auditory social interaction and control

Voice assistants—or voice-enabled artificial intelligence—have changed the way people interact with their surroundings dramatically. Utilizing an enactive view of social cognition theory, this study demonstrates how voice assistants can act as [semi] autonomous agents to hold instantaneous social interactions with consumers. This research employed two experimental studies. Study 1 used two voice assistant mobile applications, Microsoft Cortana and Google Assistant, and Study 2 used Amazon Alexa and Microsoft Cortana. The contributions this paper makes are two-fold. First, the results illustrate how perceived auditory sense drives perceived auditory control through auditory social interactions with a voice assistant that lead to brand affect and consumers’ trust in the voice assistant. Second, results shed light on the role of surprise as a repelling drive that attenuates the effect of perceived auditory control on brand affect.     

Nicknames as identity badges: How self-reflective nicknames can facilitate users’ online social interactions

An Internet nickname is essential in facilitating online interpersonal interactions. It is a pivotal element of interaction that provides other users with an initial impression and affects the decisions and behaviors of users during their online interactions. Although the existing literature has found that nicknames are relevant to users’ psychology and behavior, direct research on the motivation for and the effect of choosing a particular Internet nickname has been very limited. Borrowing from relevant theories on avatars, this paper summarizes the motivations behind Internet nickname choices in terms of three aspects: virtual exploration, social navigation and contextual adaptation. Moreover, from the perspective of collective self-esteem (CSE) and group identification, this research explores the influence mechanism between the motivations underlying Internet nickname choices and users’ online social interactions. A total of 394 samples were obtained from online communities in China to test our research model. We found that virtual exploration, social navigation and contextual adaptation are three motivations for creating Internet nicknames, and they have direct effects on the online social interactions of users. CSE has a full mediating effect between virtual exploration and online social interaction and acts as a mediated variable between social navigation and online social interaction. Group identification fully mediates the relationship between social navigation and online social interaction as well as that between contextual adaptation and online social interaction. The conclusion of this paper provides not only a new perspective for the study of Internet nicknames but also a potentially feasible way to stimulate users’ online social interactions.     

乘积型指数滤波器及其在多目标时延估计中的应用

指数滤波器是一类新构造出来的输出信噪比和目标时延分辨力随指数变化的滤波器，该滤波器在损失一定输出信噪比的前提下可以有效提高目标时延分辨力，从而提高目标时延估计精度,但仅采用单个指数滤波器仍存在输出信噪比和目标时延分辨力均达不到实际需求的情况。在乘积型高阶模糊函数乘积运算的启发下，在指数滤波器的基础上提出了一种新的乘积型指数滤波器，并分析了该乘积型指数滤波器的输出信噪比及目标时延分辨力等性能。仿真实验表明，所提的乘积型指数滤波器在低信噪比情况下可以更有效提高多目标时延估计精度，且算法简单易于实现，适用于背景复杂的多目标参数估计任务。     

职业延迟满足对员工过劳的影响研究——职业成长机会的调节作用

目前，员工过劳问题在我国企业发展中日益凸显，需要予以重视和解决。基于个体与组织互动角度，通过对338名企业员工的问卷调查分析职业延迟满足和职业成长机会对员工过劳的影响，并检验职业成长机会对职业延迟满足影响员工过劳的调节作用，结果表明：职业延迟满足的两个维度（工作延迟满足和职业生涯延迟满足）均对员工过劳有显著正向影响，而职业成长机会对员工过劳有显著负向影响；职业成长机会对职业延迟满足影响员工过劳具有负向调节作用，即职业成长机会越大，职业延迟满足与员工过劳的正向关系越弱。因此，企业管理者应合理引导和帮助员工做好职业生涯规划，为员工提供合适的多元化发展通道，以有效预防和缓解员工过劳。     

Spatial determinants of productivity growth on agri‐food Spanish firms: a comparison between cooperatives and investor‐owned firms

This study analyses the effect of the spatial factor, location, and interaction effects among peer companies, on the productivity growth of agri‐food companies in Spain. With this aim, we build a productivity growth index and apply a multiequational Seemingly Unrelated Regression on a sample of 344 Spanish cooperatives and investor‐owned firms for the period 2010–2012. Our findings show that agri‐food firms are influenced by spatial factors finding interesting differences between cooperatives and investor‐owned firms. With regard to the geographical location, cooperatives in the western of Spain show higher productivity growth rates, whereas investor‐owned firms in the northeast of Spain present better results. The interaction effect among closer peer companies is also a relevant factor to determine the productivity growth in agri‐food companies. This factor is more relevant for cooperatives than for investor‐owned firms.     

城市土地利用与交通相互作用（LUTI）研究进展与展望

研究目的:基于对国内外大量研究成果的梳理,对城市土地利用与交通相互作用(LUTI)的复杂机理展开系统回顾与述评,并尝试提出未来亟需重点关注的研究领域与方向。研究方法:文献资料法,对比分析法。研究结果:国内外实证研究领域及空间尺度表现出明显分异,部分研究结果亦呈现出差异化特征;国外热衷于引入多学科理论与方法构建LUTI一体化模型,而国内所引入的数学规划模型多停滞在理论分析与模拟层面,应用性相对有限,但近年来国内学者逐渐加强LUTI协调性评价,研究领域呈现出新特征。研究结论:全球可持续发展背景下,LUTI研究为实现城市土地利用与交通的协调发展提供了良好基础,未来应加强对LUTI模型方法与互馈机理的研究,并深入探讨现代交通发展对土地利用的影响机制,环境、社会因素亦应引起重视,国内学界则应注重本土性与应用性研究。     

MONETARY AND FISCAL POLICIES INTERACTION IN MONETARY UNIONS

In this paper, the literature on the interaction between monetary and fiscal policies in a monetary union is surveyed. By adopting the concept of symbiosis as a starting point, the paper highlights the importance of uncertainty, policy makers' preferences and targets. Then, the role of commitment to policy rules and coordination is addressed. The analysis also focuses on the importance of the data considered for the generation of the policy mix. As a final step, the paper discusses the main results in the literature on public debt management in a monetary union. All the reported theoretical results are then adopted to retrieve policy and institutional implications for the European Monetary Union.     

Emotional labor in a non-isolated service encounter - The impact of customer observation on perceived authenticity and perceived fairness

Emotional labor is a frequently discussed topic in the service literature because of its varying effects on customers' evaluation processes. Previous research has primarily investigated the effects of emotional labor from an employee-customer perspective. This article considers customer copresence and argues that the observed interaction between an employee and another customer affects the focal customer's evaluation process. An extended customer-employee-customer model is presented and empirically tested in a pharmacy setting. The findings show that distinctive emotional labor affects customers' perceptions of authenticity and fairness. This study presents a more nuanced account of the effectiveness of emotional labor and provides managers with advice to enhance point-of-sale interactions.     

Collaborative delay management towards demand-capacity balancing within User Driven Prioritisation Process

The concept of User Driven Prioritisation Process (UDPP) was introduced to give Airspace Users (AUs) more flexibility under demand-capacity imbalance. This paper presents two UDPP-DCB models, built on the UDPP principle, using the Selective Flight Protection (SFP) approach to minimize the total delay cost. AUs are enabled to adapt their operations in a more cost-efficient way in the presence of capacity constraints in airspace, optimizing their flights to keep the priorities track. Then, ATFM integrates the AUs’ decision to reassign the time slots and the preferred rerouting trajectories. Results suggest that the delay cost for AUs can be largely reduced through applying the UDPP-DCB models proposed in this paper, while allowing rerouting proves effective in reducing the system delay cost.     

创业机会共创研究探析

过往研究就创业机会的来源和产生等问题存在争议,而且聚焦于创业者、创业企业及外部环境等独立要素,割裂了创业机会在不同要素之间的互动关系。本文通过系统梳理创业机会研究的演进脉络,发现创业机会共同创造(co-creation)已成为未来研究的主要趋势。在已有研究的基础上,本文初步界定了"创业机会共创"的概念,并对相关概念进行了辨析。进一步,基于创业生态系统视角探讨了机会共创的参与要素,以此区分了实现创业机会共创的四种基本互动路径:即机会之间的互动,创业主体与机会的互动,创业主体之间的互动,创业主体与环境的互动。最后,提出了未来研究的思路与建议。
