Exploring the green image of airlines: Passenger perceptions and airline choice

During the last few years there has been an increasing trend for companies to market their products or services as green or environmentally friendly as part of their corporate social responsibility. Few studies have analyzed the effects of this recent focus on the environment and its impact on airline passengers. Therefore, we examine passengers' general attitudes towards the green image of different airlines, perceived differences in eco-friendliness among these airlines, and effects on airline choice during booking. We also investigate how passengers' recent experiences with an airline affect perceived eco-friendliness of that airline. In addition we compare passenger ratings of airline eco-friendliness to those published by independent 3rd parties. Our findings show that the green image of airlines does influence airline choice during booking. We observed a passenger willingness to pay extra for a green image, however, not as much as their willingness to pay extra for amenities, such as additional legroom.     

Eco-positioning of airlines: Perception versus actual performance

To date there has been little research in air transport into the eco-positioning of airlines, that is, their environmental image relative to other airlines and how actual environmental performance relates to this eco-positioning. This paper identifies the environmental perceptions that passengers hold of twelve airlines and relates these perceptions to airlines' actual environmental performance, using load factors, aircraft age and the atmosfair Airline index as proxies for environmental performance. Based on a survey of over 600 passengers at Liverpool John Lennon Airport, the research analyses air travellers' perception of airlines from an environmental perspective. The results show that while there are significant differences in people's environmental perception of airlines, the eco-positioning of the airlines is not correlated to their actual environmental performance. The results support previous research findings in other industries that in many cases actual performance is less important than communicating environmental messages to the public in creating a superior eco-positioning.

贵州的脱贫和发展：基于三因子耦合的解析

贵州的脱贫和发展案例表明，欠发达地区的脱贫和发展是集合“核心设施、骨干领域、环境机遇”三大因子共同发力的结果。这一发现挑战了当代主流发展理论，并在落后国家或区域具有广泛复制的价值。这种新发展观不只是一种自洽且连贯的学说，还可作为引导明智行动的机制对待，因而深具实践意义。可以把这三个强关联性词汇转换为规范且符合逻辑的陈述以激发洞见，充实当代发展理论，同时为其他不发达地区的贫困治理和经济发展提供经验和借鉴。     

Perceived hygiene attributes in the hotel industry: customer retention amid the COVID-19 crisis

The COVID-19 pandemic has caused a crisis in the hotel industry worldwide, but few studies have suggested methods to retain customers. This study proposes hygiene management as a means to minimize the indirect damage from COVID-19 to the hotel industry. It identifies perceived hygiene attributes and explores their influence on hotel image, word of mouth, and revisit intentions. This study identifies and validates three types of perceived hygiene attributes through qualitative and quantitative methods. It uses structural equation modeling to validate hypotheses and concludes that there are significant relationships of influence between the proposed variables. This study provides important and meaningful insights into hotel image and customer behavior through perceived hygiene attributes.

Online brand community within the integrated marketing communication system: When chocolate becomes seductive like a person

This study proposes brand communities as an effective tool within the integrated marketing communication (IMC) system. The paper utilizes the Brand Concept Map quali-quantitative technique in order to represent and compare mental association texture within one group of non-members of a brand community versus one group of people engaged in the same community. Brand stimulus is Nutella (chocolate cream) which boasts a crowded and lively online brand community: Nutellaville. Results show that brand community is effective in terms of contribution, commonality, and complementarity within the IMC system. In particular, Nutella brand image within the online community participants is composed of some mental associations overlapping other communication tools (commonality), and by new mental associations (complementarity) referred to the brand image dimension named ‘brand as person’ (seductive, popular, reassuring); second, this anthropomorphism effect solves the issue of sense of guilt excited by chocolate (contribution).     

物质生态批评视角下《瓦尔登湖》再解读

亨利·戴维·梭罗是美国最伟大的自然散文作家和环境主义先驱。《瓦尔登湖》是梭罗所著的一本著名的散文集。在该作品中，非人类自然的施事能力和叙事能力得到了充分体现。梭罗在肯定非人类自然与人类具有平等地位的同时，看到了其施事能力带来的影响，读懂了其叙事语言，从而向我们展示了非人类自然通过何种途径显示自身在大自然中不可替代的地位。
