Psychological comfort in service relationships: A mixed-method approach

Psychological comfort reflects the customer's peace of mind and a sense of ease during a service encounter that helps in maintaining strong relationships. However, the role of psychological comfort (PC) in retail service relationships is not fully explored. To fill this research gap, this study presents a unique conceptual model grounded in the stimulus organism response (S–O-R) framework to empirically explore the stimulating effect of customer experience on psychological comfort (PC), which influences relationships quality and customer retention as the response. To evaluate the model a quantitative survey was administered on 432 bank customers followed by in depth interviews of 10 bank employees. It was found that customer experience stimulates customer's PC that leads to relationship quality and retention as the response. It was also found that relationship duration influences the customer experience-PC relationship. The theoretical and managerial implications of the findings are discussed.     

菱铁矿在CO2气氛下热分解反应动力学研究

利用热重分析仪(TGA)研究了菱铁矿在CO₂气氛下热分解反应特性及动力学特性。结果表明:在CO₂气氛下,菱铁矿开始热分解温度为419℃,完全热分解的温度为590℃,且在512℃左右热分解速率最大。CO₂抑制了菱铁矿热分解反应过程,相对于在N2气氛下,菱铁矿完全分解所需要的时间及达到最大反应速率所需要的时间明显滞后。通过模型拟合法得到,菱铁矿在CO₂气氛热分解反应的平均表观活化能为399.9 kJ/mol,指前因子lg A为30.70,遵循的机理模型为随机成核与随后生长模型G(x)=-ln(1-x)。

大排量摩托车冷却风扇噪声测试与选型分析

随着生活水平的提高，以休闲娱乐为主的大排量摩托车越来越受到大众的青睐。噪声水平直接影响摩托车的骑乘舒适性，冷却风扇噪声作为摩托车的主要噪声源之一需要重点关注。从摩托车骑乘工况和环境噪声污染的角度出发，提出一种合理的风扇噪声测试和评估方法。以某500 cc大排量摩托车风扇为测试对象，运用LMS Test.Lab测试系统进行噪声测试分析，明确冷却风扇噪声对驾驶员耳旁和四周环境噪声的贡献量，通过选型分析锁定整车噪声更低的风扇方案，提升了摩托车的骑乘舒适性，减少了环境噪声污染。风扇噪声测试和选型分析方法可为摩托车风扇匹配提供参考。     

“Do not impose on others what you desire.” Research on the influence of service Personnel's interactive orientation on customer comfort

Comfort carries many positive consequences, and a vital issue is how to stimulate it. Because service personnel are direct service providers, which means they have a significant impact on the customer. Apparently, it is critical to improve customer comfort from the perspective of service personnel. Based on the Service Encounter theory and Regulatory Fit Theory, this paper explores how service personnel's interactive orientation, including interaction orientation, task orientation, self-orientation, influences customer comfort and examines the mediating role of perceived control and the moderating role of self-construal. We analyzed the data collected from 257 consumers using a self-reported survey using SEM with SPSS17.0 and AMOS21.0. The results show that interaction orientation has a significant positive effect on customer comfort, self-orientation has a significant negative impact on customer comfort, and task orientation has no significant impact. Perceived control plays a mediating role in the relationship between service personnel's interactive orientation and customer comfort. The moderating effect of self-construal is significant. We discussed the implications of the findings for academics and managers.
