风道结构对自提冷冻冷藏柜热性能的影响研究

冷冻冷藏柜依靠风机推动内部气流强制循环来实现柜内的冷却,通过优化风道结构可显著改善其热环境. 论文借助CFD仿真软件将某自提冷冻冷藏柜内部温度场及气流组织等结果可视化,探究风道结构对柜内热性能的影响规律. 通过改变风机方向、风道宽度及风道倾角建立多个模型进行对比,筛选出最优的结构模型. 研究结果表明:风机垂直于地面设置,风道宽度为8 cm、倾角为1.8°的冷柜内部热性能最为理想.

Understanding forced adoption of self-service technology: the impacts of users’ psychological reactance

ABSTRACT

With the rapid development of artificial intelligence, information system, and mobile technologies, some companies (e.g. airlines) consider fully replacing service employees with self-service technologies (SSTs) to cut down costs and to increase efficiency. However, replacing full services with SSTs sometimes fail to deliver the benefits companies have hoped for: users may feel that they are being forced to use SSTs and show resistance to the new technologies. To investigate why users show resistance, we draw inferences from psychological reactance theory and argue that users may perceive the forced adoption as a threat, which leads to resistance of SSTs. A conceptual model was developed and an empirical study was conducted. The results show that, under a forced situation, users are likely to perceive the forced adoption as a threat to their freedom, causing them to have negative emotions and perceptions towards the SSTs, and, in turn, their adoption intention decreases and switch intention increases. The findings provide insights on why users show resistance to SSTs and highlight the impacts of the motivational state of psychological reactance.

Factors influencing behavioural intention to patronise restaurants using iPad as a menu card

Recently, several restaurants have launched mobile technology-based self-services by replacing their printed menus with iPads. To assess the perceived value of the iPad menu from the customers’ perspective, this study proposed and tested a new research model which includes both functional and emotional aspects of customers’ attitudes. The aim was based on the supposition that an overall value judgement in regard to using the iPad menu to promote dining experience will influence customers’ behavioural intention to patronise restaurants that use the new technology; 332 usable data gathered from cyberspace were tested against the research model. The results demonstrated the importance of perceived value. All functional factors (i.e. perceived control, perceived usefulness and perceived ease of use) and emotional factors (i.e. perceived enjoyment and perceived novelty) were significantly affecting perceived value. For managers interested in investing in these mobile self-service technologies, the findings provided them with sound advice based on empirical research.
