The effect of aviation responses to the control of imported COVID-19 cases

The outbreak of the COVID-19 pandemic has a lasting and unprecedented negative impact on the global aviation industry. While countries such as China have successfully curbed the domestic outbreak of the virus with various restrictive and preventive measures, the challenge of avoiding imported cases remains. More importantly, it is still unclear to what extent these implemented aviation emergency responses have effectively mitigated the transmission risk of the virus. This paper provides an empirical assessment of aviation responses to the control of imported COVID-19 cases, with a focus on the following three strategies: the “circuit breaker” policy, the “negative Nucleic Acid testing (NAT)”, and the “double negative tests” requirement. Non-recursive structural equation models (SEM) with latent variables were applied to detailed international flight data and individual epidemic survey data of Guangzhou, China, between May 1 and November 30, 2020. The results show that the “double negative tests” measure has a positive effect on eliminating the number of SARS-CoV-2 carriers, while the effects of single “circuit breaker” and its co-intervention with “negative NAT” are conterproductive. This study provides important implications to civil aviation agencies in regard to medium and long-term risk control of imported cases. Specifically, although the circuit breaker mechanism was designed to target on the risk control of imported COVID-19 cases, it may be more effective to carefully maintain a timely and reliable pre-boarding screening and testing to curb the number of imported cases.     

赡养上一辈对中年家庭发展能力的影响路径——基于CFPS家庭配对数据的分析

利用2016年CFPS数据,从微观家庭视角,采用结构方程模型探讨多元化养老情境下赡养上一辈对中年家庭发展能力的影响路径。实证分析表明,老人的经济能力、衰老特征、失能情况三个变量对子代家庭发展能力的联合解释力为82%。老人经济能力的中介作用十分显著,且对衰老特征影响子代家庭发展能力具有遮掩效应,导致衰老叠加风险被子代家庭和公共政策所忽视。不同出生队列、育儿类型、城乡家庭群组在"失能情况通过老人经济能力影响家庭发展"这条路径上表现出明显的差异。失能引起城市老人由"小家庭"向"大家庭"的聚合,农村则相反。实施更加精准的家庭支持政策需综合考虑老人经济能力、衰老特征变化规律、失能情况以及子代家庭脆弱性。     

What drives brand love for natural products? The moderating role of household size

Natural products, including food, cosmetics, and other fast-moving consumer goods, are becoming increasingly popular, and their health-related benefits are widely recognized. Despite the growing awareness and use of natural products, little is known about the enablers and barriers that influence consumers' brand love toward them. The present study attempts to address this gap and better explain consumer behavior toward natural products by utilizing the stimuli-organism-response (S–O-R) theory. The study rests on the premise that certain stimuli influence the internal state of consumers (i.e., the organism), which, in turn, shape their response to products and services. This study uses health consciousness and environmental concern as the stimuli, both facilitators (natural content and regional product) and inhibitors (usage and image barriers) as the internal state of the ‘organism’, and brand love as the response. Based on analysis of 720 responses, the study empirically reveals that health consciousness and environmental concern significantly influence the consumers' internal state, as represented by the identified facilitators and inhibitors . Three of these, namely, regional product, image barriers, and usage barriers, are found to shape brand love for natural products. The moderating role of household size on brand love is also confirmed.The findings of the study contribute to the literature on consumer behavior and practice.     

城郊森林公园游憩满意度影响因素研究

以福州的3个城郊森林公园调查数据为研究样本,构建了城郊森林公园游憩满意度影响因素理论模型,运用结构方程模型进行验证。结果表明:游憩目的对可达程度有显著正向影响,自然环境、服务环境、管理环境分别受到游憩目的和可达程度的显著正向影响,可达程度对服务环境的满意度作用最为显著,游憩目的对管理环境的满意度作用次之。提出了提升城郊森林公园可达程度,提高游客游憩满意度,加强城郊森林公园保护管理等建议。     

Significance of attitudes,passion and cultural factors in driver’s speeding behavior in Oman: application of theory of planned behavior

Abstract

Traffic accidents and related fatalities have become a major public health problem in the world. This study aims to identify the significant factors that play an important role in the speeding behavior of drivers. A comprehensive questionnaire was designed and conducted with the students and employees of the University of Nizwa. The questionnaire items were designed considering the theoretical background of the theory of planned behavior (TPB) and local socio-cultural aspects of the driving environment. A total of 303 usable samples were obtained. The collected data were analyzed using factor analysis and structural equation modelling technique. The extracted factors of speeding passion and culture, speeding attitudes, subjective norms and perceived behavioral control are significant determinants of drivers speeding behavior in Oman. The driver’s speeding attitudes, speeding culture, and passion have positive association with the drivers’ speeding intentions and behavior, and driver’s perceived behavioral control forms negative relationship with the speeding behavior. This study confirms the application of the TPB in predicting the drivers’ speeding behavior in the context of Oman.     

The green B&B promotion strategies for tourist loyalty: surveying the restart of Chinese national holiday travel after COVID-19

This paper attempts to empirically analyze green/healthy B&B promotion strategies for tourism recovery after the first wave of COVID-19. The survey will be meaningful in the real world of B&B tourism recovery, and it was conducted during the first Chinese national holiday without travel restrictions. China was the first country to resume travel after COVID-19. Confirmatory factor analysis (CFA) and structural equation modeling (SEM) were used for testing. The relationships observed among the green/healthy physical environment, well-being perception (WBP), tourist satisfaction (TS), and tourist loyalty (TL) provide a better understanding of how to support sustainable tourism recovery. Green/healthy B&B promotion strategies that focus on a green/healthy physical environment after the health crisis can also be employed in other countries and regions experiencing the same situation.     

森林游憩环境恢复性评价影响机制研究

对环境恢复性评价的影响机制进行研究,以吉林龙湾群国家森林公园为例,尝试构建森林游憩活动中气候舒适度感知对环境恢复性评价的影响,以及二者与游客满意度和游后行为关系的结构方程模型。研究发现:气候舒适度感知正向影响环境恢复性评价,二者皆正向影响游客满意度;气候舒适度感知和游客满意度对游后行为同样有正向影响,但环境恢复性评价对游后行为不具有正向影响。因此,提高森林公园的气候舒适度和环境恢复性能更好地帮助人们恢复身心。依照研究结果,以气候舒适度及环境恢复性两个角度为公园的管理提供了相应措施及建议。     

中小企业营销道德认知与实践

对甘肃省河西地区232家中小企业进行实地调研,并进一步利用所收集到的相关数据进行归纳分析发现,河西地区中小企业经营者对企业营销道德的认知仍然处于相对较低的水平,而市场竞争的巨大压力又迫使企业在实践中履行营销道德,导致其实践相对走在了认知的前面;河西地区中小企业经营者对营销道德内涵的认知与西方企业营销道德的内涵维度相比,存在六个相似的维度,同时也存在不同之处;77%的被调研企业表示,企业营销道德与其营销绩效之间存在正相关关系。基于此,为更好地提高企业营销道德认知水平与践行力度,理论界应加大企业营销道德理论研究力度;通过正面引导和社会监督来增强企业践行营销道德的意识;建立道德营销的制度体系,加强道德文化建设。

土地要素配置如何促城乡多维融合？ ——有效市场和有为政府

研究目的：从理论和实证两方面讨论土地要素配置对城乡融合影响,为土地市场化改革提供一条可实现路径。研究方法：结构方程模型。研究结果：完全竞争条件下,土地市场化相比计划配置存在帕累托效率改进,土地市场化尤其是农地市场化对城乡融合产生直接且显著影响,并在政府行为与城乡多维融合间起多重中介作用。研究结论：城乡融合导向下中国土地要素配置的现实取向应是“有效市场+有为政府”,但须明确政府与市场边界,即发挥市场效率优势和激发政府公平优势,并通过系统体制改革,实现制度变革促效率和质量变革,最终形成城乡融合发展持续推动力。
