Intrigued by the methodological challenges emerging from text complexity, the purpose of this study is to evaluate the effectiveness of different topic modelling algorithms based on Instagram textual data.

By taking Instagram posts captioned with #darktourism as the study context, this research applies latent Dirichlet allocation (LDA), correlation explanation (CorEx), and non-negative matrix factorisation (NMF) to uncover tourist experiences.

CorEx outperforms LDA and NMF by classifying emerging dark sites and activities into 17 distinct topics. The results of LDA appear homogeneous and overlapping, whereas the extracted topics of NMF are not specific enough to gain deep insights.

This study assesses different topic modelling algorithms for knowledge extraction in the highly heterogeneous tourism industry. The findings unfold the complexity of analysing short-text social media data and strengthen the use of CorEx in analysing Instagram content.

基于对文本复杂性的兴趣, 本研究以Instagram文本数据为基准, 旨在比较不同主题建模的算法的有效性。

本研究以标有 #darktourism的Instagram帖子作为背景, 评估直观理解（LDA）, 相关解释（CorEx）和非负矩阵分解（NMF）在分析与黑暗观光相关的帖子的实用性。

CorEx分析出17个新兴的黑暗景点和活动, 亦胜过LDA和NMF。虽然LDA能探讨出较多的主题数, 但它们的内容几乎重复。同样的, 尽管NMF适用于短文本数据, 但它提取出主题相当笼统且不够具体。

透过将营销和数据科学学科相结合, 本研究为分析非结构化的文本奠定了基础, 并证实了CorEx在分析短文本社交媒体数据（如Instagram数据）中的效益。

In search of creating an extraordinary experience for customers, services have gone beyond the means of a transaction between buyers and sellers. In the event industry, where purchasing tickets online is a common procedure, it remains unclear as to how to enhance the multifaceted experience. This study aims at offering a snapshot into the most valued aspects for consumers and to uncover consumers' feelings toward their experience of purchasing event tickets on third-party ticketing platforms.

This is a cross-disciplinary study that applies knowledge from both data science and services marketing. Under the guise of natural language processing, latent Dirichlet allocation topic modeling and sentiment analysis were used to interpret the embedded meanings based on online reviews.

The findings conceptualized ten dimensions valued by eventgoers, including technical issues, value of core product and service, word-of-mouth, trustworthiness, professionalism and knowledgeability, customer support, information transparency, additional fee, prior experience and after-sales service. Among these aspects, consumers rated the value of the core product and service to be the most positive experience, whereas the additional fee was considered the least positive one.

Drawing from the intersection of natural language processing and the status quo of the event industry, this study offers a better understanding of eventgoers' experiences in the case of purchasing online event tickets. It also provides a hands-on guide for marketers to stage memorable experiences in the era of digitalization.

The breasts are mainly fatty and connective tissues with no muscles that directly support them, so wearing sports bras is one of the most effective means of alleviating the discomfort of breast movement and potential injury during vigorous physical exercise. However, the design and development processes of traditional sports bras are time-consuming and costly. Hence, a novel method of simulating the static contact pressure between a sports bra and women’s body based on the finite element (FE) and artificial neural network (ANN) models is developed in this study to contribute to the design considerations of sports bras.

Three-dimensional FE models of a female subject and sports bras with different fabric properties are developed to determine the amount of contact pressure exerted onto the body. The FE results are then verified by measuring the amount of pressure exerted by the sports bra on the skin with pressure sensors. The Taguchi technique is used to effectively reduce the number of trials from 625 to only 25 cases. These 25 results obtained through FE modelling are then used to provide the training set for the ANNs. Finally, a comparison between the FE and ANN results is carried out.

A novel model of the static contact pressure between a sports bra and human subject based on the FE and ANN methods is presented in this paper. The root mean square error values show that there is only a small difference between the FE and ANN results.

The ANN function established in this study can be used to predict the mechanical behaviours of breasts and has a fundamental impact on the computer-aided design of functional garments in general.

Hospitality and tourism research lags in using experimental designs. This study aims to reveal prestigious scholars’ opinions and suggestions on how to effectively design and execute experimental research.

The authors conducted an open-ended survey on 187 editors and editorial board members from 22 top hospitality and tourism journals. Their answers were coded following an inductive method of coding, and a list of themes and categories was synthesized.

The results summarize common problems of this method and indicate significant barriers to making experimental studies publishable. The review criteria for experimental studies are presented from four aspects: overall design, stimuli and manipulations, data collection and reporting results.

The results provide valuable suggestions for researchers interested in experimental design in the hospitality and tourism field. The study contributes to a shift toward well-designed and well-executed experimental research in hospitality and tourism.

To the best of the authors’ knowledge, the study is the first to survey editorial board members of impactful hospitality and tourism journals to reveal their insights into the experimental methodology. The study makes significant theoretical and methodological contributions by addressing calls to understand common problems and barriers to experimental research in our field.

Despite extensive study into various aspects of corporate social responsibility (CSR), the effect on consumer behaviour is less explored. A growing amount of research is concerned with the phenomenon that CSR has a minor effect on actual purchases although CSR practices enhance consumers’ purchase intentions. This is documented as the CSR-consumption paradox and is yet to be resolved. The purpose of this paper is to further understand this paradox.

Questionnaires were administered face-to-face to consumers in Birmingham. These questionnaires concern consumer behaviour in relation to CSR practices of 21 popular apparel companies in the UK.

Results suggest that consumers’ pro-social priority is significantly related to pro-social consumption and that consumers’ awareness of CSR practices is insignificantly associated with their purchase behaviour. The pro-social consumption does not differ significantly among different demographic groups.

To explore the external motivational factors in consumers’ decision making will be a potential research direction in future.

The empirical results provide implications for UK apparel marketers and policy makers to engage and motivate socially responsible consumers so as to reap strategic rewards for their CSR efforts.

This paper contributes to the knowledge of socially responsible consumption and how it is affected by CSR.

Today’s consumers are aware of restaurants’ effects on the environment and pressure them to implement green practices. As restaurant success largely depends on how employees meet customer expectations, employee green creative behavior (EGCB) is critical. Therefore, this study aims to investigate how to enhance EGCB by integrating a comprehensive set of three-dimensional components: external, organizational and individual factors.

Data analysis was conducted using responses from full-time employees in the US restaurant industry. The PROCESS macro was used to test the direct and indirect relationships between the study variables. A series of mediation analyzes were conducted to investigate the mediation effects of “restaurant ethical standards” and “employee green passion” on their relationships to “customer pressure” and EGCB.

The results verified a direct effect of “customer pressure” on “restaurant ethical standards” and EGCB. The study also demonstrated positive direct relationships of “restaurant ethical standards” – “employee green passion” and “employee green passion” – EGCB. The result showed that “restaurant ethical standards” and “employee green passion” sequentially explained the partial impact of “customer pressure” on EGCB.

The study recommends that restaurant managers acknowledge growing customer environmentalism and prepare to address their customers’ stricter green requirements. Restaurants need to review their ethical standards on a regular basis to meet rising customer pressure. The study also offers empirical evidence regarding the importance of selecting employees who are passionate about sustainability and empowering them to encourage their green creative behavior.

Although past studies have introduced various determinants of employee creative behavior, they have mainly focused on organizational and individual-level factors but have ignored a critical external factor, which is customer pressure. The study addresses this research gap by investigating the interrelationships between customer pressure and EGCB through restaurant ethical standards (organizational-level) and employee green passion (individual-level).

This paper aims to examine the environmental awareness, initiatives and performance in the Macau hotel industry.

A mixed research method was adopted involving quantitative surveys with 31 hotels in Macau and 11 face-to-face interviews with the hotel managers, facilities managers and engineers.

Response from surveys and interviews with 31 hoteliers show that hotels in Macau have a high level of environmental awareness. Most hoteliers actively introduce initiatives that contribute to cost savings. Initiatives including using energy conservation light bulbs, having an active system to detect/repair leaking facilities and installing water conserving fixtures are widely implemented, while programs involving using solar lawn light, recycling leftover food and reusing wastewater are not. Major barriers for going green include the lack of government regulations on environmental management (EM), financial constraints, the lack of employees to handle EM and the fear that environmental initiatives may negatively impact the guest’s experience, especially those VIP and hardcore gamblers and customers who expect enjoying the luxuries services in Macau hotels. Lower star hotels experience more difficulties in adopting green approaches.

This paper presents a single case study of Macau; therefore, the results in this research may have limited generalizability.

This paper is one of the very few attempts that investigate EM in Macau – a renowned world tourism and gambling destination, where the vast majority of hotels have their casino facilities. Results show that apart from the financial consideration and the lack of government enforcement to adopt green measures similar to hotels in other destinations, EM practices of Macau’s hotels are also constrained by its customer base and the acute shortage of human resources that is caused by the tourism boom.

Soft robotics is currently a rapidly growing new field of robotics whereby the robots are fundamentally soft and elastically deformable. Fabrication of soft robots is currently challenging and highly time- and labor-intensive. Recent advancements in three-dimensional (3D) printing of soft materials and multi-materials have become the key to enable direct manufacturing of soft robots with sophisticated designs and functions. Hence, this paper aims to review the current 3D printing processes and materials for soft robotics applications, as well as the potentials of 3D printing technologies on 3D printed soft robotics.

The paper reviews the polymer 3D printing techniques and materials that have been used for the development of soft robotics. Current challenges to adopting 3D printing for soft robotics are also discussed. Next, the potentials of 3D printing technologies and the future outlooks of 3D printed soft robotics are presented.

This paper reviews five different 3D printing techniques and commonly used materials. The advantages and disadvantages of each technique for the soft robotic application are evaluated. The typical designs and geometries used by each technique are also summarized. There is an increasing trend of printing shape memory polymers, as well as multiple materials simultaneously using direct ink writing and material jetting techniques to produce robotics with varying stiffness values that range from intrinsically soft and highly compliant to rigid polymers. Although the recent work is done is still limited to experimentation and prototyping of 3D printed soft robotics, additive manufacturing could ultimately be used for the end-use and production of soft robotics.

The paper provides the current trend of how 3D printing techniques and materials are used particularly in the soft robotics application. The potentials of 3D printing technology on the soft robotic applications and the future outlooks of 3D printed soft robotics are also presented.
