-wave fully charm and fully bottom tetraquark states
Authors: Chen Zhi-Zhong , Chen Xu-Liang , Yang Peng-Fei , Chen Wei 
Published: May 2024

We have studied the mass spectra of the P-wave fully charm and fully bottom tetraquark states in the framework of quantum chromodynamics (QCD) sum rules. We construct the interpolating currents by inserting the covariant derivative operator D↔μ between the S-wave diquark and antidiquark fields. The excitation structures show that the pure λ-mode excited P-wave fully heavy tetraquarks exist for the quantum numbers JPC=1−−,1−+,2−−,2−+, and 3−−, while it is difficult to separate the λ-mode and ρ-mode excitations in the 0−+ channel. Within three Lorentz indices, there is no pure λ-mode excited P-wave fully charm/bottom tetraquark operators with JPC=0−− and 3−+. Our results support that the recent observed X(6900) and X(7200) resonances could be interpreted as the P-wave fully charm ccc¯c¯ tetraquark states with JPC=1−+ and 2−+, respectively. Some P-wave fully bottom bbb¯b¯ tetraquark states are predicted to be lower than the di-ηb(1S) and di-ϒ(1S) mass thresholds. Hopefully our calculations will be useful for identifying the nature of new exotic tetraquark states.

Entanglement entropy in lattices with non-Abelian gauge groups
Authors: Hategan-Marandiuc M. 
Published: May 2024

Entanglement entropy, taken here to be geometric, requires a geometrically separable Hilbert space. In lattice gauge theories, it is not immediately clear if the physical Hilbert space is geometrically separable. In a previous paper we have shown that the physical Hilbert space in pure gauge Abelian lattice theories exhibits some form of geometric scaling with the lattice volume, which suggest that the space is locally factorizable and, therefore, geometrically separable. In this paper, we provide strong evidence that indicates that this scaling is not present when the group is non-Abelian. We do so by looking at the scaling of the dimension of the physical Hilbert space of theories with certain discrete groups. The lack of an appropriate scaling implies that the physical Hilbert space of such a theory does not admit a local factorization. We then extend the reasoning, as sensibly possible, to SU(2) and SU(N) to reach the same conclusion. Lastly, we show that the addition of matter fields to non-Abelian lattice gauge theories makes the resulting physical Hilbert space locally factorizable.

Leptogenesis driven by a Majoron
Authors: Chun Eung Jin , Jung Tae Hyun 
Published: May 2024

We propose a leptogenesis scenario where baryon asymmetry generation is assisted by the kinetic motion of the Majoron, J, in the process of lepton-number violating inverse decays of a right-handed neutrino, N. We investigate two distinct scenarios depending on the sources of a Majoron kinetic motion: (1) the misalignment mechanism, and (2) the kinetic misalignment mechanism. The former case can naturally generate the observed baryon asymmetry for the Majoron mass mJ≳TeV and the right-handed neutrino’s mass MN≳1011  GeV. However, an additional decay channel of the Majoron is required to avoid the overclosure problem of the Majoron oscillation. The later scenario works successfully for mJ≲100  keV and MN≲109  GeV while MN can be even far below the temperature of the electroweak phase transition as long as sufficiently large kinetic misalignment is provided. We also find that a sub-100 keV Majoron is a viable candidate for dark matter.

Compact objects in and beyond the standard model from nonperturbative vacuum scalarization
Authors: Del Grosso Loris , Pani Paolo , Urbano Alfredo 
Published: May 2024

We consider a theory in which a real scalar field is Yukawa coupled to a fermion and has a potential with two nondegenerate vacua. If the coupling is sufficiently strong, a collection of N fermions deforms the true vacuum state, creating energetically favored false-vacuum pockets in which fermions are trapped. We embed this model within general relativity and prove that it admits self-gravitating compact objects where the scalar field acquires a nontrivial profile due to nonperturbative effects. We discuss some applications of this general mechanism: (i) “neutron soliton stars” in low-energy effective QCD, which naturally happen to have masses around 2M⊙ and radii around 10 km even without neutron interactions; (ii) “Higgs false-vacuum pockets” in and beyond the standard model; (iii) “dark soliton stars” in models with a dark sector. In the latter two examples, we find compelling solutions naturally describing centimeter-size compact objects with masses around 10−6M⊙, intriguingly in a range compatible with the Optical Gravitational Lensing Experiment (OGLE)+Hyper Suprime-Cam (HSC) microlensing anomaly. In addition to these interesting examples, the mechanism of nonperturbative vacuum scalarization may play a role in various contexts in and beyond the standard model, providing a support mechanism for new compact objects that can form in the early Universe, can collapse into primordial black holes through accretion past their maximum mass, and serve as dark matter candidates.

Optimizing corrosion resistance of Fe35Ni20Cr12Mn28Al5 high-entropy alloy: synergistic effect of Mo inhibitor, Al content and cold rolling
Authors: Elkatatny Sally , Zaky Lamiaa , Abdelaziem Walaa , Abdelfatah Aliaa 
Published: May 2024

Purpose
This study aims to investigate the corrosion behavior of cold-rolled Fe35Ni20Cr12Mn(28-x)Alx high-entropy alloys (HEAs) using the potentiodynamic polarization technique in 1 M H2SO4 acid. Additionally, the influence of molybdenum (Mo) additions as inhibitors and the effect of variations in cold rolling reduction ratios and Al content on corrosion behavior are examined.

Design/methodology/approach
Two cold rolling reduction ratios, namely, 50% (R50) and 90% (R90), were examined for the cold-rolled Fe35Ni20Cr12Mn28Al5 (Al5) and Fe35Ni20Cr12Mn23Al10 (Al10) HEAs. Mo inhibitor additions were introduced at varying concentrations of 0.3, 0.6 and 0.9 Wt.%. The potentiodynamic polarization technique was used to evaluate the corrosion rates (CRs) under different experimental conditions.

Findings
The results indicate that the addition of 0.3 Wt.% Mo in 1 M H2SO4 yielded the lowest CR for both R50 and R90, irrespective of the Al content in the HEAs. However, the highest CR was observed at 0.6 Wt.% Mo addition. Furthermore, increasing the concentration of Al resulted in a corresponding rise in the CR. Comparatively, the CR decreased significantly when the cold rolling reduction ratio increased from R50 to R90.

Originality/value
This research provides valuable insights into the intricate relationship between Mo inhibitors, cold rolling reduction ratio, Al content and the resulting corrosion behavior of Fe35Ni20Cr12Mn(28-x)Alx HEAs. The comprehensive analysis of corroded HEAs, including surface morphology, compositions and elemental distribution mapping, contributes to the understanding of the corrosion mechanisms and offers potential strategies for enhancing the corrosion behavior of HEAs.
Why I revisit a historic town in Chengdu? Roles of cognitive image, affective image and memorable tourism experiences
Authors: Zhou Xue , Ng Siew Imm , Deng Weiwei 
Published: May 2024

PurposeBuilding upon the cognition-affect-behavior (CAB) model and script theory, this research aims to enrich the existing literature on historic town tourism consumption by offering empirical evidence of how the cognitive and affective images of historic towns contributes to tourists' memorable tourism experiences (MTE) and revisit intention, while identifying the cognitive image dimensions that are relevant for evaluating historic towns.Design/methodology/approachAn on-site survey was conducted with 486 local tourists who visited the historic towns in Chengdu. partial least squares-structural equation modeling (PLS-SEM) was utilized to assess both the measurement and structural models.Findings(1) Cognitive image emerged as a significant predictor of affective image; (2) Both cognitive image and affective image had a positive influence on MTE, in which cognitive image played a more dominant role in shaping MTE; (3) MTE was found to strongly predict revisit intention among tourists; (4) MTE and affective image mediated the relationship between cognitive image and revisit intention.Research limitations/implicationsThis research highlights the value of incorporating cognitive and affective constructs in predicting MTE, and the proposed integrated framework of the CAB model and script theory exhibits superior predictive power in understanding tourists' revisit intention.Practical implicationsThis research provides empirical insights about how historic towns improve their marketing strategies as short day-trip destinations.Originality/valueThis research provides a novel insight on the applicability of an integrated model combining the CAB model and script theory in explaining the revisit behavior of local tourists within the context of historic towns.
CEO childhood trauma experience and firm internationalization
Authors: Du Yongzhi , Xiang Yi , Ruan Hongfei 
Published: May 2024

Purpose
The purpose of this study is to examine how the childhood trauma experiences of CEOs influence firms’ internationalization.

Design/methodology/approach
The research used a difference-in-difference method with constructing a treatment group whose chief executive officer (CEO) experienced the great famine in China between the ages of 7 and 11, and a control group whose CEO was born within three years after 1961.

Findings
The study reveals a significant inverse correlation between CEOs’ childhood trauma experiences and firm internationalization. However, this correlation is weaker in the case of state-owned enterprises and firms led by CEOs with overseas work experience.

Originality/value
To the best of the authors’ knowledge, this study is the first to extend the theoretical framework to elucidate firms’ internationalization by introducing childhood trauma theory into the field of international business literature. Second, the authors link the literature on the effect of CEO explicit traits and psychological traits on firm internationalization by exploring how CEOs’ childhood trauma experience shapes their risk aversion, which, in turn, influences firm internationalization. Third, the authors address the call for examining the interplay of CEO life experiences by scrutinizing the moderating effect of CEO overseas work experience on the association between CEOs’ childhood trauma exposure and firm internationalization.
Queer dancers’ experiences in the dancesport world: exclusion, invisibilisation and assimilation
Authors: Meneau Val 
Published: May 2024

PurposeThis paper intervenes in the consequences of a myth propagated in academic discourse about the dancesport world, according to which half of the men in Latin dancesport are gay. I challenge two assumptions that surround this myth: that cisgender gay men do not contribute to the reification of the heteronormative gender binary, and that the dancesport scene is inclusive of gay people. These assumptions are based on a blatant lack of understanding of the position of gay men within the dancesport world – that is, the ways in which subjects are constituted through the effects of power.Design/methodology/approachThis work is based on empirical research I conducted in the dancesport community, including ethnographic and autoethnographic fieldwork, extant documents (e.g. books, blogs, Judging Regulations) and interviews with experts and participants of the dancesport scene (2021/2022). To analyse the data, I relied on the principles of dispositive analysis, grounded theory and dance analysis.FindingsI show that gay dancers have turned to assimilation as their only available strategy. I discuss the negative consequences of assimilation as a political strategy and how it impacted queer dancers – between invisibilisation, residual shame and a failure to challenge the heteronormative gender binary. This led gay dancers to rationalise and perpetrate harm based on the systems of oppression they had internalised.Social implicationsI conclude the paper by highlighting a way beyond assimilation for queer dancers.Originality/valueThis paper addresses a critical gap in research on LGBT + inclusion in dancesport.
Leading with understanding: cultivating positive relationships between neurotypical leaders and neurodivergent employees
Authors: Szulc Joanna Maria 
Published: May 2024

PurposeNeurodivergent employees have atypical needs that require distinctive leadership approaches. In this study, the specific nature of a relationship between neurodivergent employees and their neurotypical leaders is explored through the lens of the leader–member exchange (LMX) theory.Design/methodology/approachThis two-phased qualitative study builds on 12 semi-structured interviews with neurodivergent employees and an unstructured focus group with 15 individuals with professional and/or personal interest in neurodiversity. The researcher spent almost 13 h listening to the lived experiences of research participants concerning neurodiversity and leadership.FindingsLeaders who exhibit empathy and understanding were noted to provide greater support. The findings also highlight the complexity of neuro-inclusion in the workplace. Specifically, the delicate balance between accommodation and avoiding stigmatization is emphasized, addressing the concerns raised regarding the legal risks associated with neurodivergent inclusion. Additionally, the findings underscore the necessity for leaders to avoid patronizing behaviors while catering to the diverse needs of neurodivergent employees. This underscores the importance of supporting both neurodivergent employees and leaders navigating such challenges.Practical implicationsThe findings help establish inclusive and accommodating employee relations practices that conscientiously address the requirements of neurodivergent employees while providing support for those in leadership roles.Originality/valueThis study constitutes a direct answer to recent calls to develop a more nuanced understanding of workplace neurodiversity, with a specific focus on neuro-inclusive leadership. Acknowledging that we still use inappropriate, old tools in new situations that require novel approaches to leadership helps set the agenda for future research in this area.

Authors: Shafei Hazwani , Rahman Rahimi A. , Lee Yong Siang 
Published: May 2024

Purpose
Built environments are highly vulnerable to climatic disasters such as extreme floods, droughts and storms. Inaccurate decisions in adopting emerging construction technologies can result in missed opportunities to improve the resilience of built environments. Therefore, understanding the effectiveness of emerging construction technologies in improving built environment resilience can help in making better strategic decisions at the national and organizational levels. This study aims to evaluate the effectiveness of Construction 4.0 technologies in improving built environment resilience.

Design/methodology/approach
A list of Construction 4.0 technologies was adopted from a national strategic plan. Then, the data were collected using the fuzzy technique for order preference by similarity to ideal solution technique from selected built environment experts to determine the relative effectiveness of Construction 4.0 technologies in improving built environment resilience.

Findings
Six Construction 4.0 technologies are critical in improving built environment resilience (in rank order): building information modeling, autonomous construction, advanced building materials, big data and predictive analytics, internet of Things and prefabrication and modular construction. In addition, adopting Construction 4.0 technologies collectively is crucial, as moderate to strong connections exist among the technologies in improving built environment resilience.

Originality/value
To the best of the authors’ knowledge, this is one of the first papers that evaluate the effectiveness of Construction 4.0 technologies in improving built environment resilience. Industry professionals, researchers and policymakers can use the study findings to make well-informed decisions on selecting Construction 4.0 technologies that improve built environment resilience to climatic disasters.
A comparative analysis of corporate rescue and insolvency laws in Zimbabwe and Mauritius
Authors: Mahadew Bhavna , Ganga Tinotenda 
Published: May 2024

Purpose
The primary purpose of this study is the development of Zimbabwe's rescue culture. The current framework for rescue operations was shaped by the historical development of laws pertaining to insolvency and liquidation. Socioeconomic pressures in Zimbabwe can be attributed to some of the main factors that led to the need for rescue legislation and restructuring, which in turn fueled the shift from a culture that supported credit to one that supported debtors. The aim of this study is to offer an overview of the key ideas and principles of the corporate rescue programs now implemented in Mauritius and to investigate the ways in which these ideas and principles impacted the newly enacted Zimbabwean Insolvency Act.

Design/methodology/approach
This study adopts a comparative legal approach using Zimbabwe and Mauritius as comparative case studies. The fact that both countries are former British colonies and their insolvency legal framework inspired by common law makes them appropriate to be compared. Legislation and case law are used to conduct the comparative study with the aim of Zimbabwe drawing lessons from the Mauritian legal framework on insolvency. Mauritius is a nearly ideal subject for a comparative case study because of its vibrant and fairly successful bankruptcy law framework, as well as its fictional corporate rescue culture. These might provide Zimbabwe with some motivation and guidance.

Findings
The legal framework on insolvency in Zimbabwe has been found to be too stringent and does not provide companies with any lifeline. There is arguably a tendency of forcing companies out of business rather than implementing a rescue culture. Selected aspects of the Mauritian legal framework on insolvency can be mapped onto the Zimbabwean system to implement a much-needed rescue culture given its challenging economic context.

Originality/value
This study contributes to comparative legal literature in the field of insolvency. It is among the very few research work that compares the legal structure on insolvency of Zimbabwe and Mauritius in a collaborative endeavor to enhance the insolvency law and its application in Zimbabwe.
Unveiling the driving forces behind high non-performing loans in zombie enterprises: an executive-centric study
Authors: Bai Min , Zhang Dong , Zhao Wenzhuo 
Published: May 2024

PurposeExcessive borrowing significantly contributes to pushing businesses towards default and their transition into zombie enterprises. Despite government efforts to implement deleveraging policies and guide bank credit flows, it’s essential to delve into the internal dynamics that steer the borrowing behavior of these zombie enterprises at a micro level. To gain a comprehensive understanding of the issue, this study focuses on examining the incentives that drive corporate executives of zombie enterprises to consistently engage in large-scale borrowing from banks.Design/methodology/approachIn this study, panel data analysis is utilized, incorporating firm-, industry- and year-fixed effects. Drawing from data pertaining to listed companies in China spanning from 2007 to 2020, we employ a one-by-one identification method to pinpoint zombie enterprises. Ultimately, a total of 2,533 samples of zombie enterprises were obtained.FindingsThe results indicate that as bank loans to zombie enterprises increase, executive monetary compensation decreases, while on-the-job consumption by executives increases, and they are less likely to be forced into rotation. Mechanism testing reveals that corporate performance partially mediates the relationship between bank loans and executive monetary compensation, but this mediation is ineffective for on-the-job consumption and job rotation. Further investigation suggests that the property rights nature of central enterprises and modified audit opinions can exacerbate the adverse impact of bank loans on the monetary compensation of zombie corporate executives, without significantly affecting on-the-job consumption or job rotation. Conversely, executive power does not enhance the positive effects of bank loans on monetary compensation or on-the-job consumption, but it diminishes the negative impact of bank loans on the forced rotation of zombie executives.Research limitations/implicationsThese results indicate that while bank loans may have a negative impact on corporate value, they function as safeguards for the positions and interests of executives. As a result, bank loans serve as incentives for executives of zombie enterprises.Originality/valueThis study holds theoretical significance as it explores the motivations behind non-performing loans in high-borrowing enterprises, sheds light on corporate governance challenges encountered by zombie enterprises and provides policy insights aimed at addressing the underlying causes of persistent non-performing loans in high-borrowing enterprises, including zombie enterprises.
From awareness to behaviour: understanding cybersecurity compliance in Vietnam
Authors: Tran Dien Van , Nguyen Phuong V. , Le Linh Phuong , Nguyen Sam Thi Ngoc 
Published: May 2024

Purpose
This paper aims to investigate the influence of cybersecurity awareness and compliance attitudes on the protective behaviours exhibited by employees. This study also aims to explore the complex correlation between the level of awareness about cybersecurity measures and attitudes towards compliance with these measures. Additionally, it looks at how these factors collectively impact employees’ behaviour to protect organisational assets and information.

Design/methodology/approach
This study uses a quantitative research methodology in which primary data are gathered using a survey questionnaire distributed to personnel employed at Vietnamese organisations. The data are analysed, and the validity of the measurement and structural equation model is assessed using a partial least squares–structural equation model approach after the collection of all the survey responses.

Findings
The provision of policies and security education, training and awareness programmes are strongly and positively associated with cybersecurity awareness. Moreover, cybersecurity awareness plays an important role in shaping attitudes and intentions towards information security policy compliance (ISPC). Attitude is positively associated with intention towards ISPC and employee protective behaviour. Finally, the intention towards ISPC is significant in shaping employee protective behaviour.

Originality/value
This study contributes to the understanding of the antecedents of cybersecurity in developing countries such as Vietnam. Furthermore, it provides a comprehensive framework for understanding intention and protective behaviour through cybersecurity awareness and compliance attitudes. By combining the theory of planned behaviour and protection motivation theory with institutional governance, this study extends previous research on the effects of these variables on employee protective behaviour.
