Abstract

Purpose

This paper aims to classify the sentiment of online tourism-hospitality reviews at an aspect level. A new aspect-oriented sentiment classification method is proposed based on a neural network model.

Design/methodology/approach

This study constructs an aspect-oriented sentiment classification model using an integrated four-layer neural network: the bidirectional encoder representation from transformers (BERT) word vector model, long short-term memory, interactive attention-over-attention (IAOA) mechanism and a linear output layer. The model was trained, tested and validated on an open training data set and 92,905 reviews extrapolated from restaurants in Tokyo.

Findings

The model achieves significantly better performance compared with other neural networks. The findings provide empirical evidence to validate the suitability of this new approach in the tourism-hospitality domain.

Research limitations/implications

More sentiments should be identified to measure more fine-grained tourism-hospitality experience, and new aspects are recommended that can be automatically added into the aspect set to provide dynamic support for new dining experiences.

Originality/value

This study provides an update to the literature with respect to how a neural network could improve the performance of aspect-oriented sentiment classification for tourism-hospitality online reviews.

Abstract

Purpose

The purpose of this paper is to explore how a neo-liberal nationalist discourse of China imagines the spatial identity of the post-1997 Hong Kong with reference to Lost in Hong Kong, a new Chinese middle-class film in 2015 with successful box office sales.

Design/methodology/approach

Textual analysis with the aid of psychoanalysis, postcolonial studies and semiotics is used to interpret the meaning of the film in this study. The study also utilizes the previous literature reviews about the formation of the Chinese national identity to help analyze the distinct identity of the Chinese middle class today.

Findings

The discussion pinpoints how the new Chinese middle class as neo-liberal nationalists take Hong Kong as a “bizarre national redemptive space”. While Hong Kong is cinematically constructed as such a national other, this paper argues that the Hong Kong in question stands not for itself but in a form of “reverse hallucination” for pacifying the new Chinese middle class’ trauma under the rapid neo-liberalization of China in the 1990s.

Originality/value

This paper shows the new of formation of the Chinese nationalist’s discourse, especially the new Chinese middle-class discourse on Hong Kong after 1997.

Abstract

Purpose

This paper aims to study the influence of the dimension change of bush-pin on the pressure, oil film thickness, temperature rise and traction coefficient in contact zone by using a thermal elastohydrodynamic lubrication (EHL) model for finite line contact. Concretely, the effects of the equivalent curvature radius of the bush and the pin, and the length of the bush are investigated.

Design/methodology/approach

In this paper, the contact between the bush and pin is simplified as finite line contact. The lubrication state is studied by numerical simulation using steady-state line contact thermal EHL. A constitutive equation Ree–Eyring fluid is used in the calculations.

Findings

It is found that by selecting an optimal equivalent radius of curvature and prolonging the bush length can improve the lubrication state effectively.

Originality/value

Under specific working conditions, there exists an optimal equivalent radius to maximize the minimum oil film thickness in the contact zone. The increase of generatrix length will weaken the stress concentration effect in the rounded corner area at both ends of the bush, which can improve the wear resistance of chain.

Abstract

Purpose

Mixed products, while presenting new business opportunities, raise considerable concerns among managers and researchers. However, whether mixed products (functionally vs culturally) trigger positive or negative consumer reactions is controversial. Hereby, the present research seeks to resolve the conflicting effects by examining the moderating role of service provider type (humanoid service robot vs human employee) in the impact of mixed products on consumer reactions.

Design/methodology/approach

Two studies were conducted to explore the effect of mixed products on consumer reactions. Specifically, study 1 was developed to examine the interplay of mixed products and service provider type in shaping consumers' product attitudes and purchase intentions under an offline shopping scenario; study 2 further provided evidence for the mediating roles of perceived usefulness and perceived enjoyment in the above processes under an online-shopping context.

Findings

The convergent findings of two studies conclude that, when served by a humanoid service robot (vs human employee), consumers exhibit more positive attitudes and higher purchase intentions toward functionally (vs culturally) mixed products. Furthermore, such effect is driven by the perceived usefulness (vs perceived enjoyment) when served by humanoid robot (vs human employee).

Originality/value

First, this is one of the first studies to conceptualize mixed products as the two-dimensional construct (i.e. functionally mixed and culturally mixed), and the findings sheds light on the mixed products literature. Second, this paper introduces service provider type as the boundary condition for the impact of mixed products on consumers' product attitudes and purchase intentions, which expands the match-up hypothesis and schema theory in service marketing. Third, the current research explores the mediating roles of perceived usefulness and perceived enjoyment in the above effects, which could make significant contribution to the motivation theory.

The purpose of this paper is to investigate the dynamic characteristics of a spiral groove liquid film seal considering the effect of cavitation.

Abstract

Purpose

The purpose of this paper is to investigate the dynamic characteristics of a spiral groove liquid film seal considering the effect of cavitation.

Design/methodology/approach

A mathematical model of a spiral groove liquid film seal was established based on the mass-conserving Jakobsson–Floberg–Olsson cavitation boundary condition. The film rupture and film reformation boundaries were assumed to be unchanged under infinitesimal perturbation conditions. Governing equations under steady and perturbed states were solved by the finite element method, and then the dynamic characteristics of the spiral groove liquid film seal were theoretically investigated considering the effect of cavitation.

Findings

The results indicate that dynamic coefficients considering cavitation are smaller than those neglecting cavitation. The difference value is consistent with the change in cavitation area. The liquid film seal does not suffer axial instability whether considering cavitation, but its angular instability is more likely to occur when cavitation is considered.

Originality/value

For liquid lubricated non-contacting mechanical seals, the dynamic characteristics considering cavitation are investigated. The results are expected to provide a theoretical basis for improving the design method of liquid film seals.

Abstract

Purpose

Drawing on the signaling theory and the relational exchange theory, this study investigates how buyer–supplier trust is influenced through the congruence and incongruence between blockchain and norm of solidarity. The moderating role of technology uncertainty is further examined.

Design/methodology/approach

Using a survey data of 110 Chinese firms, this study empirically tests not only the combined effect of blockchain and norm of solidarity on trust, but also how this combined effect is moderated by technology uncertainty. The proposed hypotheses are tested using the polynomial regression analysis and the response surface methodology.

Findings

The results suggest that trust increases along with an increasing congruence between blockchain and norm or solidarity, but in a diminishing rate (i.e. an inverted U-shaped relationship). Simultaneously, incongruence between blockchain and norm of solidarity can also guarantee sufficient trust (i.e. a U-shaped relationship). Moreover, technology uncertainty overturns the inverted U-shaped relationship between blockchain and norm of solidarity congruence on trust into a U-shaped relationship and nullifies the U-shaped relationship between blockchain and norm of solidarity incongruence on trust.

Originality/value

This study enriches supply chain governance literature by introducing the emerging blockchain governance and examining the blockchain governance's interplay with a conventional relational norm. The study emphasizes that the combined effects of these two are quite complex. Blockchain and norm of solidarity can offset each other’s limitations when both are at low to moderate levels. But simultaneous pursuit of both high blockchain and norm has only limited marginal benefits. Furthermore, the study also highlights the importance of technology uncertainty under which the combined effects between the two governance mechanisms vary. Collectively, the results provide nuanced insights into the design of supply chain governance portfolios in the digital era.

Abstract

Purpose

This paper aims to explore students’ work-integrated learning experience. Particularly, students’ application of knowledge and improvement of multiple skills in work-integrated learning, their influence on positive industry image change due to the COVID-19 pandemic, and students’ desired career prospect were explored.

Design/methodology/approach

A questionnaire survey with valid responses from 168 undergraduate students in hospitality and tourism management was conducted in four colleges/universities in Guangdong, China in 2021. PLS-SEM method was used to analyze the data.

Findings

It was found that students’ multiple skills had improved through application of knowledge in work-integrated learning. Skill improvement helped form positive industry image change and shape future career prospect. However, such positive industry image change did not impact students’ career prospect directly.

Originality/value

Today, work-integrated learning has become one of the most valuable opportunities for students in hospitality and tourism management to gain industry experience. However, recent literature has largely examined the negative impacts of COVID-19, whereas few studies have examined the positive aspects of work-integrated learning.

Abstract

Purpose

The purpose of this paper is to explore the restrictive effect of abusive supervision on employees’ feedback-seeking behavior (FSB) through organizational-based self-esteem (OBSE) and the moderation of this mediation by leader-member exchange (LMX).

Design/methodology/approach

This study conducted hierarchical regression and path analysis to analyze the 312 manager–employee dyads data gathered from five companies in China.

Findings

The authors found that abusive supervision had a detrimental effect on employee FSB, partially through OBSE, and that both the direct and indirect effects were moderated by LMX.

Practical implications

Organizations should seek to inhibit supervisors’ abusive behavior in the workplace. Supervisors should not occasionally mistreat subordinates with whom they have a good relationship.

Originality/value

This study reveals the underlying influence mechanism of abusive supervision on employee FSB using the self-concept theory and suggests that OBSE is critical in determining how abusive supervision influences employee FSB. Furthermore, LMX quality (especially high LMX) moderates the above mediation.

Abstract

Purpose

Indoor localization is a key tool for robot navigation in indoor environments. Traditionally, robot navigation depends on one sensor to perform autonomous localization. This paper aims to enhance the navigation performance of mobile robots, a multiple data fusion (MDF) method is proposed for indoor environments.

Design/methodology/approach

Here, multiple sensor data i.e. collected information of inertial measurement unit, odometer and laser radar, are used. Then, an extended Kalman filter (EKF) is used to incorporate these multiple data and the mobile robot can perform autonomous localization according to the proposed EKF-based MDF method in complex indoor environments.

Findings

The proposed method has experimentally been verified in the different indoor environments, i.e. office, passageway and exhibition hall. Experimental results show that the EKF-based MDF method can achieve the best localization performance and robustness in the process of navigation.

Originality/value

Indoor localization precision is mostly related to the collected data from multiple sensors. The proposed method can incorporate these collected data reasonably and can guide the mobile robot to perform autonomous navigation (AN) in indoor environments. Therefore, the output of this paper would be used for AN in complex and unknown indoor environments.

Abstract

Purpose

The purpose of this paper is to examine the harmful effect of abusive supervision on employee creativity through feedback-seeking behavior (FSB) and the moderation of this mediation by proactive personality.

Design/methodology/approach

This study conducted hierarchical regression and path analysis to analyze the 341 manager–employee dyads data gathered from 11 companies in China.

Findings

The results reveal that abusive supervision had a detrimental effect on employee creativity partially mediated by employee FSB, and employees' proactive personality moderated the mediation.

Research limitations/implications

Although the findings of this research are based on multiple sources data, it is hard to draw causal inferences because the nature of the data is cross-sectional.

Practical implications

Organizations should be aware of the deleterious effect of abusive supervision on employee creativity and should seek to inhibit supervisors' abusive behavior in the workplace.

Originality/value

This study re-examines the relationship between abusive supervision and employee creativity in the Chinese context from the social exchange perspective. The mediating role of FSB and the moderating role of proactive personality offer new insights in-to the mechanisms and boundary conditions associated with the relationship between abusive supervision and employee creativity.
