The permeate flux in microfiltration (MF) declines sharply with time due to membrane fouling, which seriously restricts its use in industrial applications. The purpose of this paper is to investigate particles deposition in MF processes, and propose a three-dimensional numerical model that focuses on particle-fluid flow and considers both permeable boundary conditions and cake deposition.

The two-ways coupling model was solved using Euler-Lagrange methods in which the suspended particle was traced by a hard sphere model and the fluid was simulated using large eddy model.

The numerical results predicted based on this model demonstrated the permeate flux increased as trans-membrane pressure and inlet velocity increased but decreased with an increase in feed concentration.

Good agreement was observed between the values obtained with the model and experimental values from the literature. The error is less than 20 per cent both permeate flux and cake thickness. In addition, a precise visualisation of cake morphology with filtration time was provided.

These analyses allowed for an estimation of the three-dimensional motion of suspended particles in turbulent flow. It saves manpower and financial resources for experiment, which possess important theoretical and industrial significance.

The purpose of this study is to investigate the interactive effect of timing and framing of hotel’s upselling message on consumer attitudes toward the message. The mediating role of reactance between the timing of upselling message and consumer attitudes is also explored.

A 2 (timing: immediately after the booking vs one week prior to arrival) by 2 (framing: concrete vs abstract) experimental design was used. A total of 250 Chinese consumers were recruited and were randomly exposed to a hotel online upselling scenario. The consumer attitudes and reactance were measured.

When the framing of upselling message involves specific room attributes, consumers show more favorable attitudes when receiving the promotion one week prior to arrival (vs immediately after the booking). However, when the framing of upselling message involves price, consumer attitudes do not differ across the time of receiving the promotion. Reactance mediates the effect of message timing on consumer attitudes when the message framing involves specific room attributes.

This research suggests that hotel managers should offer concrete message framing that includes specific room attributes at the time proximal to consumers’ arrival to increase acceptance of online room upselling. In addition, it is important for hotel managers to take consumers’ reactance into consideration when developing an online upselling strategy.

Research on online hotel room upselling is scant. This study adds to the upselling literature by examining the joint influence of timing and framing of upselling promotions on consumer attitudes toward such messages. Furthermore, this study extends our understanding of the role of reactance in the online upselling process.

This research aims to find out the reasons why Chinese people prefer domestic products. The authors examine the effect of consumer ethnocentrism (CE), social norms (SNs) and national identity (NI) on willingness to buy (WTB) domestic products in two time points and test the product category differences and age group differences.

Two survey studies (n₁ = 314; n₂ = 346) were conducted in China in 2021 and 2022, respectively. The authors measured CE, SNs, NI and WTB domestic products in both studies and WTB four categories of products in study 2. Multiple hierarchical linear regression was conducted to test the hypotheses.

In study 1, the authors found that SNs and NI significantly predicted WTB domestic products, but CE did not. In study 2, the authors found that all three indicators significantly predicted WTB domestic products. CE played a significant and consistent role in different product categories, while SNs and NI had inconsistent effects. NI predicted WTB domestic products for younger people but not for older people.

This research is the first to examine CE, SNs and NI in the same study and the first to explore the role of SNs and NI in WTB domestic products in China. It promotes the understanding of CE and other related factors, increases the knowledge of Chinese consumers’ purchasing behavior and indicates the power of the situation. Practical implications are also discussed.

This study aims to investigate the impact and mechanism of new energy vehicle (NEV) information sources (IS) on mass consumers' purchase intentions (PIs) in China.

Around 902 valid questionnaires were collected using the questionnaire to analyze the different effects of three types of IS (official, interpersonal and commercial) on mass consumers' PIs. Besides, this study investigates the mechanisms by examining the mediating effect of perceived risk (PR) and the moderating effect of individual differences like age and education level.

The three types of NEV IS stimulate the PI of mass consumers, but there are some differences, with interpersonal information sources (IISs) having the strongest contribution, followed by official information sources (OISs) and commercial information sources (CISs) the least. Meanwhile, PR plays a mediating role in the effect of NEV IS on mass consumers' PIs, and age and education level moderate the influence paths. Specifically, the moderating effect of age mainly works on the negative impact of PR on PI, while education level moderates the influence of IS on PR.

This study contributes to filling the gaps in the current understanding of the role played by NEV IS in shaping consumer preferences and choices. It provides valuable insights for automotive manufacturers, policymakers and marketers to tailor their marketing strategies and improve information dissemination to effectively promote NEV adoption among mass consumers.

Management response to consumer comments has become a widely adopted marketing strategy to address the undesirable effects caused by negative remarks. Yet, when and what management response is more effective and under what circumstances remains under-researched. This study aims to fill this gap.

In three experiments using five different products, the authors manipulate psychological construal level (psychological distance: distant vs proximal) and management response (response of primary vs secondary features) and thereafter assess their bearings on consumer psychological and behavioral reaction toward products of two distinctive natures (hedonic vs utilitarian).

At a psychological distance, consumers show a preferable reaction to management response of primary over secondary features. In contrast, when the psychological distance is proximal, consumers react more positively to management response of secondary than primary features. In addition, these effects vary as a function of product nature, hedonic vs utilitarian.

The findings of this research bring a significant contribution to marketing communication literature and extend the construal level theory.

A better understanding of the relative effectiveness of distinct types of management response to negative consumer comments is essential for more targeted and effective marketing strategies.

Little research has documented the effects of distinct types of management response. How psychological distance might underpin these effects has not been explored. In addition, whether the interaction effect of management response and psychological distance varies with differences in product nature, namely, hedonic and utilitarian, remains unanswered until this research.

As a complex social emotion, awe includes both positive emotion and negative emotion. But few studies have explored the downstream effects and psychological mechanisms of two different types of awe. As a self-transcendence emotion, awe will arouse the small self, that is, reduce self-awareness. In the era of the sharing economy, the obstacle to sharing is the strong self-awareness that consumers have built about their belongings. Therefore, this paper aims to explore how two different types of awe can affect consumers' sharing, especially with different relationships.

This study conducted two experiments to test the effect of awe on consumer sharing of their own products. Study 1 aimed to examine the main effect of different awe on consumer sharing of their product as well as the underlying mechanism. Study 2 aimed to examine the interacting role of tie strength in the effect of awe on consumer product sharing.

Through two empirical tests, the authors have found that, relative to the control group, the sense of awe arouses the feeling of small self and significantly increases the consumers' willingness of sharing. Also, the authors have found that threat-based awe which leads to self-diminishment is more conducive to promoting the sharing of weak ties; on the contrary, the nonthreat-based awe which leads to a feeling of vastness is more conducive to promoting the sharing of strong ties.

This research expands the literature in the field of sharing. While the mainstream sharing a focus on information sharing, this research extends it to product sharing. What is more important is, this research explores how to encourage sharing to weak ties, which contributes to sharing economy.

The purpose of this paper is to investigate consumers' purchase intention of wild freshwater fish. Facing the endangering ecology in the Yangtze River Basin, the Chinese government has implemented a ten-year fishing ban policy to protect the wild freshwater fishery resources from 2020. In this context, such questions are raised as how do consumers react to this and are they willing to reduce or even refuse to purchase wild freshwater fish to protect the aquatic biological resources in the Yangtze River Basin?

A total of 1,235 consumers from eight provinces (including two province-level municipalities) in the Yangtze River Basin filled out the online questionnaires. The data (n = 1,096) are analyzed by structural equation model (SEM) to verify the relationships between the variables.

The results show that subjective norm is the strongest direct determinant of purchase intention, followed by personal norm, attitude, environmental concern and perceived behavioral control. It is also found that attitude, subjective norm, perceived behavioral control and environmental concern have significant effects on personal norm which plays a significant mediating role in forming purchase intention. On this basis, specific policy recommendations are proposed.

This paper investigates consumers' purchase intention from the perspective of ecological protection and obtains a more comprehensive explanation of the purchase intention by combining the theory of planned behavior (TPB) and theory of norm activation.

This study aims to investigate the impact of travel advisory perception and cultural distance on travel intention based on the push and pull theory, the stimulus–organism–response model and protection motivation theory.

The paper conducts an empirical test with a questionnaire survey. The authors asked respondents to answer questions on a five-point Likert-type scale, which included threat severity, threat susceptibility, advisory perception, perceived cultural distance, travel motivation and travel intention.

In this paper, through a questionnaire of 424 respondents, the authors found that threat severity has a positive impact on advisory perception and perceived cultural distance, and that advisory perception indirectly affect travel intention through travel motivation.

Previous literature has discussed the influencing factors of travel intention but rarely does it consider the intrinsic relationship and interaction between advisory perception and cultural distance. The results of this study help fill some gaps in the research on advisory perception and perceived cultural distance, guide governments on how to better formulate travel advisories and provide a new perspective for tourism industry practitioners to improve their travel products after the COVID-19 pandemic especially.

New-age technologies are driving brand digitalization and influencing consumer retail experiences and consumption patterns. Although past research addresses users’/consumers’ acceptance of these technologies in retail, it refrains from thoroughly studying interaction and engagement. Stemming from the technology acceptance model, the purpose of this paper is to empirically study the practicality of the technology-enabled engagement process comprising stages of interaction, psychological engagement, value-in-use and behavioral engagement during consumers’ interactions with augmented reality, artificial intelligence and machine learning based virtual try-on services.

Data from an online survey conducted in China of 339 consumers who experienced the virtual-try-on service is analyzed using partial least squares-structural equation modeling.

The results support the technology-enabled engagement process of brand virtual try-on services. Perceived ease of use and usefulness are robust antecedents of the framework during the interaction stage. Emotional and cognitive aspects contribute to the psychological engagement and value-in-use stages that convert into positive e-word of mouth and buying intentions about the brand in the behavioral engagement stage.

The research contributes to the technology acceptance model, information systems and technology marketing literature by testing a novel technology-enabled engagement process, which previously lacked empirical validation. Specifically, it uses technology acceptance model constructs as antecedents of the technology-enabled engagement process framework, with behavioral intentions in the form of e-word of mouth and buying intentions as precedents. It also provides insights into brands’ virtual try-on services in online retail environments. Practical implications for brand managers are discussed.

Electronic waste (e-waste) such as discarded computers and smartphones may contain large amounts of confidential data. Improper handling of remaining information in e-waste can, therefore, drive information security risk. This risk, however, is not always properly assessed and managed. The authors take the protection motivation theory (PMT) lens of analysis to understand intentions to protect one's discarded electronic assets.

By applying structural equation modeling, the authors empirically tested the proposed model with survey data from 348 e-waste handling users.

Results highlight that (1) protection intention is influenced by the perceived threat of discarding untreated e-waste (a threat appraisal) and self-efficacy to treat the discarded e-waste (a coping appraisal) and (2) optimism bias plays a dual-role in a direct and moderating way to reduce the perceived threat of untreated e-waste and its effect on protection intentions.

Results support the assertions and portray a unique theoretical account of the processes that underline people's motivation to protect their data when discarding e-waste. As such, this study explains a relatively understudied information security risk behavior in the e-waste context, points to the role of optimism bias in such decisions and highlights potential interventions that can help to alleviate this information security risk behavior.
