The hospitality and tourism industry faces serious challenges during public health emergencies such as COVID-19. Managers are concerned not only about how to maintain business and provide humanized services but also about social distancing. This study presented artificial intelligence (AI) technology-based service encounters as a possible solution and examined the antecedents and consequences of the encounter triad including customers, employees, and AI. Based on a systematic literature review, the study identified 4 modes of AI technology-based service encounters: AI-supplemented, AI-generated, AI-mediated, and AI-facilitated encounters. In addition, the study developed an integrated model to specify the factors that influence AI technology-infused service encounters in general and the customer service outcomes that result from the encounters. The findings contribute to service management and AI application theoretically and practically. 相似文献

Despite being a high-risk population, epidemiological research about injuries among homeless individuals is limited. We sought to describe injury characteristics among individuals identified as homeless in the National Electronic Injury Surveillance System (NEISS), and to compare them to age- and sex-matched controls. We searched text narratives for all patients with product-related injuries who presented to NEISS emergency departments from 2007 to 2011 to identify homeless cases (N = 268). A random sample of 2680 age- and sex-matched controls was identified for the same time period. The incident location differed between groups, and the mention of substance use was significantly more common among homeless cases than controls. The body part injured differed significantly between cases and controls for all age groups, with the exception of older adults. Among homeless cases, injuries occurred most frequently to the lower extremities, and sprains/strains, contusions/abrasions and burns were most common. Additional research on injury among homeless individuals is warranted in order to identify meaningful preventive strategies for this at-risk population. 相似文献

人工收集和整理2012—2018年在中国市场上映的首轮院线电影信息数据,构建电影需求的嵌套logit回归模型,以新冠肺炎疫情为准自然实验,来量化突发公共事件对电影行业复产复工的影响。结果显示:第一,关于上映时间选择,在恢复营业后,如果所有因为疫情尚未上映的电影选择顺延上映能有效避免过度竞争的局面。第二,关于上映节奏控制,控制好未定档电影的上映节奏,保持适当的竞争能促进经济效益提升。其中,从11月份开始以每周两部的频率上映未定档电影的经济效益最佳。第三,关于上映方式选择,与线下播放相比,疫情期间选择线上播放能及时收回成本并有利于经济收益最大化的实现。研究结论为电影行业制定复产复工策略提供依据,为未来应对突发公共卫生事件提供参考。 相似文献

当前小体积远端射频单元(Remote Radio Unit,RRU)主要是皮站级别的Pico-RRU,其重量和体积仍然难以满足掌上型的要求。为此,采用高集成度的AD9361芯片来实现长期演进(Long Term Evolution,LTE)宽带收发信机功能,配合时钟同步模块、放大器模块和控制接口电路等一起构建低成本的掌上型RRU。主要解决了基于AD9516的时钟同步、低相位噪声设计和高灵敏度接收机设计三个技术难点,成功实现了掌上型、高性能、低成本的设计目标。整个RRU样机尺寸为18 cm×10 cm×2 cm,质量约500 g,量产成本千元以内。测试表明,该RRU下行误差向量幅度(Error Vector Magnitude,EVM)小于3%,优于3GPP要求的8%;10 MHz带宽时上行接收机灵敏度优于3GPP要求的-93.5 dBm。 相似文献

This study aimed to identify the roles of laypeople at road traffic injuries (RTIs). A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The key words of ‘laypeople’, ‘layman’, ‘layperson’, ‘bystander’, ‘first responder’, ‘lay first responder’, ‘road traffic’, ‘road traffic injury’, ‘crash injury’, ‘crash scene’, ‘emergency’, ‘trauma care’, and ‘prehospital trauma care’ were used in combination with the Boolean operators OR and AND. We did electronic search on Google Scholar, PubMed, ISI Web of Science, CINAHL, Science Direct, Scopus, ProQuest. Based on the reviewed studies, some factors such as cultural conditions, knowledge, relief agencies, and demographic factors affect the interventions of laypeople at the crash scene in functional areas. Regarding the permanent presence of people at the crash scene, the present study can provide an opportunity to reduce different side effects of RTIs imposed on the society. 相似文献

中国应急物流政策研究(上) 总被引:1,自引:1,他引:1
在应急物流的体制、政策和预案问题上,我们必须遵循成本-效能原则,按照效率最高、效果最好、成本最低的总思路进行全面科学合理的系统化设计,并进行事后的评估和改进.为此,要建立信息化、精确化、高效率、低成本、快捷灵敏、安全可靠的应急物流管理体制,切实加强应急物流的组织管理和信息化建设,加强应急物流的成本一效能分析和数据库建设,加强应急物流通道建设,建立专业化的应急物流指挥体系和完善的应急物资配送体系.同时,中国迫切需要探索一条减少实物储备和静态储备,以最小实物储备量和最大能力储备量,来最有效地应对最复杂突发事件的新路子. 相似文献

随着中国每年出境人数的急剧增加,海外华人利益的保护就逐渐成为中国政府高度关切的课题。中国作为国籍国对海外华人利益的保护包括外交保护、领事保护和应急保护机制。这3种既相互联系但又有区别,而在最近发生的国际重大事件中,应急保护机制不断显现出其现实性和实用性。本文从应急保护机制及其相关概念的深入剖析入手,结合目前他国和我国应急保护机制的做法,提出了完善我国应急保护机制的重大意义和相应做法。 相似文献
