Abstract
Purpose
The purpose of this paper is to assess the performance of competing methods and model selection, which are non‐trivial issues given the financial implications. Researchers have adopted various methods including statistical models and machine learning methods such as neural networks to assist decision making in direct marketing. However, due to the different performance criteria and validation techniques currently in practice, comparing different methods is often not straightforward.
Design/methodology/approach
This study compares the performance of neural networks with that of classification and regression tree, latent class models and logistic regression using three criteria – simple error rate, area under the receiver operating characteristic curve (AUROC), and cumulative lift – and two validation methods, i.e. bootstrap and stratified k‐fold cross‐validation. Systematic experiments are conducted to compare their performance.
Findings
The results suggest that these methods vary in performance across different criteria and validation methods. Overall, neural networks outperform the others in AUROC value and cumulative lifts, and the stratified ten‐fold cross‐validation produces more accurate results than bootstrap validation.
Practical implications
To select predictive models to support direct marketing decisions, researchers need to adopt appropriate performance criteria and validation procedures.
Originality/value
The study addresses the key issues in model selection, i.e. performance criteria and validation methods, and conducts systematic analyses to generate the findings and practical implications.

Abstract
Three types of industrial buyer-seller relational process models are available: joining theory, stage theory, and state theory. However, historically, these models have developed based on the knowledge and cultural context of the Western world. Several researchers note that national culture may have an impact on international industrial buyer-seller relationships. Including culture in the models is highly important, especially as the business environment is increasingly more global and different countries have different business cultures. The goal of this paper is to define the most suitable industrial buyer-seller relational process models for describing relationships in various contexts. The paper includes a through literature review and a single case study in order to reach this objective. A new state theory model evolved during the research. It consists of two beginning states: searching and starting; four purely middles states: constant/static, decline, growth, and troubled; and a purely end state: termination. The state of dormant/inert is both a middle state and an end state, that is, when the relational actors are not in contact does not mean that the relationship has ended, but instead, for example, new legislation may have been implemented, which requires the actors to evaluate their relationship and its future. A relationship goes through the two beginning states in the order mentioned above, but after that, any state may occur.

Abstract
With its worldwide fame for making action films, Hong Kong cinema has been defined as masculine. Action films, including the costumed martial arts films and the modern gangster films, have been a major genre in Hong Kong cinema from the 1960s on. Despite the dominant masculinity, women still play significant roles in some of these films. In fact, fighting women leave footprints in the history of Hong Kong cinema, which precede their counterparts in the West and even provide models for Hollywood after 2000.
This chapter focuses on the female characters portrayed by the acclaimed Hong Kong director Wong Kar-wai, whose works have an ambiguous connection to mainstream genres. He modifies Hong Kong action films and creates unconventional female characters such as the drug dealer in Chungking Express (1994), the killer dispatcher in Fallen Angels (1995), the swordswoman in Ashes of Time (1994), and the kung fu master in The Grandmaster (2013). Wong's films have been mush discussed in academia, but the gender images therein are quite ignored. With high intertextuality, these characters are used to question mainstream action films and redefine women's roles in male's cinematic space. In addition, via the writing of these women, Wong constructs an open and ambivalent post-colonial Hong Kong identity. This paper contextualises the figures of sword-wielding and gun-shooting women and examines how Wong Kar-wai deploys these images to articulate the cultural identity of a post-colonial city.

Abstract
Purpose
Despite the promising development and marketing potential of the metaverse, our understanding of how realistic metaverse environments impact user engagement and behaviours remains limited. This study investigates the role of perceived realism in influencing user engagement, thereby affecting external search behaviour and visit intentions.
Design/methodology/approach
We surveyed 270 active metaverse users to test the research model. The data were analysed using partial least squares structural equation modelling (PLS-SEM).
Findings
The results of our study show that three dimensions of realism – avatar involvement, perceptual pervasiveness and social realism – significantly enhance user engagement, which in turn influences external search behaviour and visit intention. In contrast, simulation realism and freedom of choice have minimal effects on absorption and dedication.
Research limitations/implications
This study highlights the role of perceived realism in enhancing user engagement with the metaverse and its impact on physical world behaviours. It contributes to metaverse literature by demonstrating that engagement within the metaverse significantly influences physical world behaviours, including visit intentions and external search behaviours.
Practical implications
This study offers practical guidance for developers to enhance user engagement in metaverse environments. Specifically, our findings advocate for visual and audio quality enhancements, greater persuasiveness of virtual spaces, improved avatar representativeness and a closer alignment of metaverse activities with real-life events.
Originality/value
This study advances the theoretical understanding of perceived realism by examining how its dimensions – such as visual and audio quality, avatar representativeness and alignment with real-life events – impact user engagement in the metaverse. It also explores how this engagement influences offline behaviours, thus bridging the gap between virtual and real-world interactions.

Abstract
Introduction: Media representation of intimate partner violence (IPV) can influence public opinion and understanding of the phenomena and guide health policies. The current review has the aim to explore and discuss international, scientific literature focused on the portrayal of IPV in written forms of news media.
Method: Searching through EBSCO and PubMed, 2,435 studies were found and 41 were included in the current review.
Results: Bias in the portrayal of IPV was found within the studies included. While IPV-related news was mainly focused on male-perpetrated violence within heterosexual couples, little attention was paid to same-sex intimate partner violence (SSIPV). Newsworthy stories dominate IPV reporting within news media and a sensationalistic style was often employed. Furthermore, contextual information was often limited and the adoption of a thematic frame was rare, while news media were found to commonly employ an episodic frame. Official sources and family, friends and neighbours were the most quoted sources in news articles, while IPV experts were rarely drawn on for information. Regarding media representation of perpetrators, mainly regarding male abusers, news articles reported several reasons behind the violence with the consequence to justify and exonerate them from their responsibilities. Female perpetrators were found to be depicted, in some cases, as ‘mad’ or ‘bad’ people. Finally, victim-blaming content emerged within many of the articles included.
Conclusion: Bias in the media representation of IPV emerged in the current review, which needs to be addressed to positively influence public opinion and to promote an adequate understanding of the phenomena.

The purpose of this paper is to explore the emergence of civil disobedience (CD) movements in Hong Kong in the context of the notion of civil society (CS).
Abstract
Purpose
The purpose of this paper is to explore the emergence of civil disobedience (CD) movements in Hong Kong in the context of the notion of civil society (CS).
Design/methodology/approach
The paper begins by rigorously defining the notion of CD, as well as the concept of CS and tracing its development in Hong Kong over the past several decades. By using a model of CS typology, which combines the variables of state control and a society’s quest for autonomy (SQA), the paper aims to outline the historical development of CD movements in Hong Kong. It also discusses the recent evolution of CS and its relationship with CD movements, particularly focusing on their development since Leung Chun-ying became the Chief Executive in 2012. Finally, by using five cases of CD witnessed in the past several decades, the relationship between the development of CS and the emergence of CD in Hong Kong has been outlined.
Findings
Four implications can be concluded: first, CD cannot emerge when the state and society are isolated. Second, the level of SC and the scale of CD are positively related. Third, as an historical trend, the development of SQA is generally in linear progress; SQA starts from a low level (e.g. interest-based and welfare-based aims) and moves upwards to campaign for higher goals of civil and political autonomy. If the lower level of SQA is not satisfied, it can lead to larger scale CD in future. Fourth, the CD movement would be largest in scale when the state-society relationship confrontational and when major cleavages can be found within CS itself.
Originality/value
This paper serves to enrich knowledge in the fields of politics and sociology.

Abstract
Purpose
Through the theoretical lenses of media richness, perceived realism and customer engagement, this study aims to investigate the mechanisms that promote customer engagement in metaverse-mediated environments in the meetings, incentives, conferences and exhibitions (MICE) context, as well as the impact of customer engagement on customers’ metaverse usage intensity and future visit intention.
Design/methodology/approach
A survey of customers who have experience with metaverse-mediated MICE activities was conducted. Data from 267 respondents were analysed using partial least squares-structural equation modelling and fuzzy-set qualitative comparative analysis (fsQCA) to test our research framework.
Findings
Media richness dimensions, including multiple cues, immediate feedback and personal focus, were found to enhance perceived metaverse realism, which in turn affects the dimensions of customer engagement, leading to customers’ metaverse usage intensity and future visit intention. The fsQCA analysis identifies three configurations that lead to high event visit intention.
Practical implications
This research helps developers and marketers better understand how rich media contents create realistic experiences in the metaverse, aiding them to devise strategies for customer engagement and improve resource allocation.
Originality/value
Despite its potentially revolutionary impacts, empirical studies on the mechanisms driving customer engagement in the metaverse and its effects are scarce. This study contributes by revealing the multiple-phase mechanism of the customer engagement journey in the metaverse-mediated MICE context. By expanding the media richness theory into this area, our study provides new insights by illustrating how media richness dimensions create multisensory experiences and real-time interactions, enhancing perceived metaverse realism and customer engagement. It also addresses the debate on whether metaverse-mediated events substitute or complement real-life events.

Abstract
This chapter examines how the breakthrough of Zhang Ziyi's depiction of a female kung fu master in The Grandmaster (2013) transforms the figure of the heroine in Chinese action films. Zhang is well known for her acting in action films conducted by renowned directors, such as Ang Lee, Zhang Yimou and Wong Kar-wai. After winning 12 different Best Actress awards for her portrayal of Gong Ruomei in The Grandmaster, Zhang announced that she would no longer perform in any action films to show her highest respect for the superlative character Gong. Tracing Zhang's transformational portrait of a heroine in The Grandmaster alongside her other action roles, this analysis demonstrates how her performance projects the directors' distinctive gender viewpoints. I argue that Zhang's characterisation of Gong remodels heroine-hood in Chinese action films. Inheriting the typical plot of a daughter's use of martial arts for revenge for her father's death, Gong breaks from conventional Chinese action films that highlight romantic love during a woman's adventure and the decisive final battle scene. Beyond the propensity for sensory stimulation, Gong's characterisation enables Zhang to determine that women can really act in action films – demonstrating their inner power and ability to create multi-layered characters – not merely relying upon physical action. This chapter offers a relational perspective of how women transform the action film genre not merely as gender spectacles but as embodied figures that represent emerging female subjectivity.

Abstract
Purpose – This chapter aims to explore the strategies used by the Hong Kong government to respond to the adult worker model and the male-breadwinner model; and to explore the views of women on the desirability of these strategies. The male-breadwinner model posits that men work full-time outside the home and women take on domestic work. The adult worker model suggests that women and men should be equally expected to participate in formal employment.
Design/methodology/approach – This chapter analyses the policy measures used by the Hong Kong government to support women in their participation in formal employment and the local work-based pension scheme (the Mandatory Provident Fund) as well as other policy measures that offer potential for enabling family care providers to accumulate resources for secure retirement. Additionally, it draws on semi-structured interviews with 30 Hong Kong young women to examine their views on the extent to which the government supports them to save pension incomes.
Findings – This study shows that the Hong Kong government uses a ‘weak action strategy’ to respond to the adult worker model and the male-breadwinner model, and that this strategy fails to meet women’s diverse preferences for their roles in the labour market and the family.
Originality/value – Based on a newly developed framework, this study examines the responses made by the government to both the male-breadwinner model and the adult worker model. It sheds new insights into possible ways of assisting women to achieve secure retirement .
