This study aims to construct a two-step model to examine how passive (mental imagery and immersion) and active (engagement) responses build a spatial presence in 360° virtual tours by constructing the spatial situation. This study further tests the difference between first-time and repeat users in building a spatial presence.

Systematic sampling was applied to collect data. Valid data from 355 participants were analysed using partial least squares structural equation modelling.

The results show that other than the direct effect of engagement on spatial presence, the spatial situation partially mediates the effects on the spatial presence of two passive responses. Through comparative analysis of the three models, this study confirms that the two-step model provides a better fit for the data. For repeat users, the spatial situation is the major source of spatial presence.

The results offer suggestions for destination marketers to develop effective virtual tours to induce the spatial presence of repeat users and first users.

This study contributes a two-step model for researchers to consider the mediating role of the spatial situation in further studies in the context of virtual reality (VR) tourism. This study also helps researchers design their future VR research in tourism by elucidating the roles of passive and active psychological responses in determining spatial presence.

研究发现为目的地营销人员提供了建议, 以开发有效的虚拟旅游从而诱导重复用户和首次用户的空间呈现。

本研究为研究人员提供了一个两步模型, 以考虑空间状况在 VR 旅游背景下的进一步研究中的中介作用。 这项研究还通过阐明被动和主动心理反应在确定空间呈现中的作用, 帮助研究人员设计他们未来的旅游 VR 研究。

The purpose of this study is to examine how a hotel virtual reality photography (VRP) preview enhances customers’ immediate booking intention compared to a picture preview.

Data were collected using a one-factor between-subject experimental design and time-based systematic sampling. Respondents were asked to read a scenario on an iPad and assess a hotel preview (VRPs vs pictures) before answering the questionnaire.

The results show that a hotel VRP preview generates more mental imagery than a picture preview in terms of quantity, vividness, modality and valence. These four dimensions of mental imagery indirectly influence customers’ immediate booking intentions through perceived utilitarian value and hedonic value, among which modality has the greatest influence on utilitarian value and valence has the greatest influence on hedonic value. Moreover, utilitarian value has a stronger impact on customers’ immediate booking intentions than does hedonic value.

The results obtained in this study contribute to hospitality research by using cognitive consistency theory as the overarching framework, combining mental imagery theory, media richness theory and perceived value theory to explain the mechanism of tourists’ hotel booking decision-making from hotel previews. Comparing this study’s results with previous studies shows the difference in the effects of 360° (head-mounted) videos, VRPs and pictures on evoking mental imagery across tourism and hotel products, updating our knowledge of VR technology in tourism marketing.

本研究旨在探讨与图片预览相比, 酒店虚拟现实摄影（VRP）预览如何增强客户的即时预订意图。

本研究采用单因素被试间实验设计和时间系统抽样收集数据。受试者在 iPad 上阅读场景并评估酒店预览（VRP与图片）, 然后填写问卷。

结果表明, 酒店VRP预览在心理意象的数量、生动性、感官模式和情感效价方面比图片预览生成更多的心理意象。这四个维度的心理意象通过感知的工具价值和享乐价值间接影响客户的即时预订意图, 其中感官模式对工具价值的影响最大, 情感效价对享乐价值的影响最大。此外, 工具价值对客户的即时预订意图的影响强于享乐价值。

本研究利用认知一致性理论作为总体框架, 结合心理意象理论、媒介丰富度理论和感知价值理论, 解释了游客在酒店预览中做出预订决策的机制。本研究结果与以往研究相比, 展示了360°（头戴式）视频、VRP和图片在唤起旅游和酒店产品心理意象方面的差异, 更新了我们对旅游营销中VR技术的理解。

The purpose of this paper is to examine the factors that influence mainland Chinese film tourists’ behavioural intention in accepting an augmented reality (AR) feature film character-related tour APP (an IfilmAR-tour-APP) based on an extension of unified theory of acceptance and use of technology (UTAUT) model.

Systematic sampling was used to collect data; 360 valid questionnaires were collected from mainland Chinese film tourists visiting Macau. Partial least squares structural equation modelling (PLS-SEM) was applied to analyse the data.

The findings indicated that performance expectancy, effort expectancy, social influence, celebrity involvement and personal innovativeness have a significant impact on mainland Chinese film tourists’ behavioural intention in accepting the IfilmAR-tour-APP, while facilitating conditions do not significantly affect tourists’ behavioural intention. Furthermore, the study revealed that effort expectancy, celebrity involvement and personal innovativeness positively influence performance expectancy in the use of an IfilmAR-tour-APP.

The findings of this study provide implications for AR tour APP developers which will help them to enhance their designs, and for the governments of tourist destinations to formulate their promotion strategies in developing niche tourism.

This study extended the application of UTAUT to tourism technology by introducing two personality traits in the context of AR tour APPs for film-induced tourism. This research contributes to niche tourism research by linking niche tourism and tourism technology.

China was the only developing country that participated in the human genome project and contributed 1 per cent of human genome sequencing in 2000. And it finished rice genome sequencing independently in 2002. China’s biomedical industry, however, remains largely an academic affair. The industry is characterized by its inability to support and commercialize innovative research, which in turn has resulted in the prevalence of generic drugs. Managers of Chinese firms have been focusing on the shortterm profits that can be generated by generics rather than the longer‐term potential profits arising from innovative research. But the viability of such short‐cut strategy is now called into question as the IPR infringements will mean hefty fines to the violators in the wake of China’s WTO accession. There is hence an urgent need to make the timely transformation from academic affair to commercialization. This paper examines the reasons why biomedical industry remains largely an academic affair in China by stacking China against the key success factors of biomedical industry in the world. It then suggests the ways to make the transformation by filling the gap between basic research and commercial products and cultivating the necessary business environment for biomedical drugs in China.

Blockchain has been considered as a disruptive technology and every industry stands to benefit from it. According to Deloitte, increasing number of managers claim that their firms will suffer loss in competitive advantage if they do not adopt blockchain. Despite this motivation, insufficient knowledge on how can blockchain add value inhibits the commitment to its adoption. To better understand the possible influence of blockchain, two dimensions (exploitation and exploration) of blockchain initiatives are distinguished. This research aims to examine the impact of ambidextrous blockchain initiatives on firms' operational efficiency, as well as the moderating role of unabsorbed slack and environmental munificence.

In this paper, secondary panel data were collected from multiple sources to test the proposed hypotheses. Content analysis was adopted to operationalise ambidextrous blockchain initiatives from firms' official announcements.

The authors find that firms' ambidexterity in blockchain initiatives have significantly positive impact on operational efficiency. Furthermore, when firms have lower unabsorbed slack or in more munificent environments, they may benefit from managing a balance between exploration and exploitation.

This research offers some insightful theoretical and managerial implications of ambidextrous blockchain initiatives. The findings of this study contribute to blockchain literature by providing theory-driven empirical research.

This study aims to investigate the effect of changes in iron content in 70/30 copper–nickel alloy on the corrosion process.

70Copper–30Nickel-xFe-1Mn (x = 0.4,0.6,0.8,1.0 Wt.%) alloy were prepared by the high frequency induction melting furnace. The scanning electron microscope, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and electrochemical impedance spectroscopy were used to analyze the morphology and component of the corrosion product film.

The results show that the corrosion resistance of 70/30 copper–nickel alloy added with 1.0%Fe is the best, and the film is divided into inner dense Cu2O composite film and outer hydration loose layer; XRD showed that after adding 1.0% Fe, the content of Cu2(OH)3Cl in the corrosion product film was significantly reduced, while the content of Cu2O remained unchanged; XPS showed that nickel accumulates in the inner layer of corrosion product film; the stage growth mode of the film, the role of nickel in it and the enrichment mechanism of iron in the inner film were summarized and discussed.

The changes in the composition and structure of the corrosion product film caused by the iron content are revealed, and the mechanism of the difference in corrosion resistance is discussed.

In recent years, the rapid growth of big data has presented immense potential for business applications as well as raised great interest from academia. In response to this emerging phenomenon, the purpose of this paper is to provide a comprehensive literature review of big data.

A bibliometric method was used to analyze the articles obtained from the Scopus database published between 2013 and 2018. A sample size of 4,070 articles was evaluated using SciVal metrics.

The analysis revealed an array of interesting findings as follows: the number of publications related to big data increased steadily over the past six years, though the rate of increase has slowed since 2014; the scope of big data research is quite broad in regards to both research domains and countries; despite a large volume of publications, the overall performance of big data research is not well presented as measured by the field-weighted citation impact metric; collaboration between different institutions, particularly in the form of international collaboration and academic–corporate collaboration, has played an important role in improving the performance of big data research.

To the best of the authors’ knowledge, this is the first study to provide a holistic view of the big data research. The insights obtained from the analysis are instrumental for both academics and practitioners.

An organization’s ability to successfully manage intellectual capital is determined by the actions of its employees to prevent or minimize information security incidents. To prevent more data breaches to intellectual capital, organizations must provide regular cybersecurity awareness training for all personnel. The purpose of this paper is to investigate the effect of different evidence-based cybersecurity training methods on employees’ cybersecurity risk perception and self-reported behavior.

The study participants were randomly assigned into four groups (i.e. malware report, malware videos, both malware report and malware videos and no interventions) to assess the effects of cybersecurity training on their perceptions of vulnerability, severity, self-efficacy, security intention as well as their self-reported cybersecurity behaviors.

The results show that evidence-based malware report is a relatively better training method in affecting employees’ intentions of engaging in recommended cybersecurity behaviors comparing with the other training methods used in this study. A closer analysis suggests whether the training method contains self-relevant information could make a difference to the training effects.

This paper reports an in-depth investigation on how different evidence-based cybersecurity training methods impact employees’ perceptions of susceptibility, severity, self-efficacy, security intention as well as on their self-reported cybersecurity behaviors.

This study aims to investigate the effect of coatings prepared by the addition of copper-aluminum alloy powder on the corrosion behavior of 90/10 copper-nickel alloy.

Coatings of copper-aluminum alloy powder at different contents (Wt.% = 50%, 60%, 70% and 80%) were prepared by the high-temperature heat treatment process. The microstructure and component of the coatings were characterized by scanning electron microscope, X-ray diffraction, energy dispersive spectrometer and X-ray photoelectron spectroscopy. The electrochemical properties of the coating were explored by electrochemical impedance spectroscopy.

The results show that the aluminized layer was successfully constructed on the surface of 90/10 copper-nickel alloy, the composition of the coating was composed of copper-aluminum phase and aluminum-nickel phase, the existence of the aluminum-nickel phase was formed by the diffusion of Ni elements within the substrate and because of the diffusion, the Al-Ni phase was distributed in the middle and bottom of the coating more. The Al-Ni phase is considered to be the enhanced phase for corrosion resistance. When the copper-aluminum alloy powder content is 70 Wt.%, the corrosion resistance is the best.

The enhancement of corrosion resistance of 90/10 copper-nickel alloy by the copper-aluminum alloy powder was revealed, the composition of the aluminized layer and the mechanism of corrosion resistance were discussed.

This paper draws on the perspective of social networks to examine when 3PLs initiate low-carbon supply chain integration (LCSCI) in decarbonising supply chains.

A questionnaire survey was conducted on a sample of 348 Chinese 3PLs. Stepwise regression was adopted to analyse the data.

It is found that LCSCI has a positive effect on firm performance. From the social network perspective, a larger scope of outsourcing increases 3PLs' embeddedness, which increases their chance of success in initiating LCSCI, especially for 3PLs with higher decarbonisation capabilities. Interestingly, although the pressure from government regulation can also motivate LCSCI, it is less effective for 3PLs with higher decarbonisation capabilities because they can be too embedded in the network to freely adapt to regulations.

This study has investigated 3PL-initiated LCSCI only from the view of 3PLs. A dyadic approach which includes the perception of customers would be desirable.

The results highlight the critical role of 3PLs as supply chain orchestrators in decarbonising supply chains, and the effectiveness of LCSCI as a competitive strategy of 3PLs. Coercive pressures from government regulations are not constraints but resources for 3PLs in initiating LCSCI, especially in markets where the 3PLs have insufficient decarbonisation capabilities.

This study contributes to theories on 3PLs' interorganizational low-carbon initiatives, LCSCI, and the paradox of social networks in supply chains.
