Axi-Majoron: One-shot solution to most of the big puzzles of particle cosmology
Authors: Barenboim Gabriela , Ko Pyungwon , Park Wan-il 
Published: December 2024

The details of the minimal cosmological standard model (MCSM) proposed in [The minimal cosmological standard model, .] are discussed. The model is based on the scale-symmetry and the global Peccei-Quinn (PQ) symmetry with a key assumption that the latter is broken only in the gravity sector in a scale-invariant manner. We show that the model provides a quite simple unified framework for the unknown history of the Universe from inflation to the epoch of big-bang nucleosynthesis, simultaneously addressing key puzzles of high energy theory and cosmology: (i) the origin of scales, (ii) primordial inflation, (iii) matter-antimatter asymmetry, (iv) tiny neutrino masses, (v) dark matter, and (vi) the strong CP-problem. Scale symmetry can be exact, and the Planck scale is dynamically generated. The presence of Gauss-Bonnet term may safely retain dangerous nonperturbative symmetry-breaking effects negligible, allowing a large-field trans-Planckian inflation along the PQ-field. Isocurvature perturbations of axi-Majorons are suppressed. A sizable amount of PQ-number asymmetry is generated at the end of inflation, and conserved afterward. Domain wall problem is absent due to the nonrestoration of the symmetry and the nonzero PQ-number asymmetry. Baryogenesis can be realized by either the transfer of the PQ-number asymmetry through the seesaw sector, or by resonant leptogenesis. Dark matter is purely cold axi-Majorons from the misalignment contribution with the symmetry-breaking scale of O(1012)  GeV. Hot axi-Majorons from the decay of the inflaton become a natural source for a sizable amount of dark radiation. Inflationary gravitational waves have information about the mass parameters of the lightest left-handed and right-handed neutrinos, thanks to the presence of an early matter-domination era driven by the long-lived lightest right-handed neutrino species.

Enterprise-wide risk management in higher education: beyond the paradigm of managing risk by categories
Authors: Bamber Christopher , Elezi Enis 
Published: December 2024

PurposeThe global higher education (HE) sector is facing difficult challenges worldwide. Thus, we investigate risk management (RM) practices within HE with three purposes in mind: (1) embedding knowledge management (KM) concepts into the drivers of enterprise-wide risk management (EWRM); (2) providing a road map for embedding RM elements utilising a risk-focused preparation, planning, doing, checking and action (P,PDCA) approach to the management of risks in HE; and (3) rendering KM more readily applicable to EWRM thus enhancing the management of risk.Design/methodology/approachIn this qualitative research, we examined the intersection of theories of EWRM in HE and KM concepts while considering our existing knowledge and previously formed ideas about the complex phenomena of successfully implementing risk management. Additionally, we took into account our researchers’ and practitioners' epistemological dispositions with regard to the value of KM. We applied a methodical analytic approach to gain a greater understanding of EWRM in HE. Following a focused literature review of EWRM in HE and KM, we integrated RM implementation models with KM concepts to answer three research questions: (1) How can higher education institutions (HEIs) effectively manage EWRM by pinpointing specific risks within selected categories? (2) To what extent could adopting RM enablers enhance RM practices in HEIs? and (3) Are HEIs mitigating unforeseen outcomes by implementing risk management strategies?FindingsWe have analysed six drivers of EWRM from a KM perspective, demonstrating that KM concepts can support the successful implementation of risk enterprise-wide. A multifaceted yet practical model has emerged by linking the interconnecting concepts of RM and KM, which provides a holistic approach to implementing EWRM in HE. The emergent model was critically reviewed and discussed by eight senior sector practitioners, and their viewpoints and suggestions have been taken into consideration.Originality/valueOur research has pinpointed, analysed and verified deficiencies in the present understanding of the factors that impact the effective execution of RM. Consequently, this investigation contributes to the comprehension of the potential of KM in fostering a nurturing environment that enables successful EWRM in HE. In view of these discoveries, we suggest adopting an all-encompassing approach to RM that incorporates top-down, bottom-up and combined approaches, which can enrich risk awareness and ultimately minimise unanticipated outcomes.

Leading the innovation: role of employee engagement as a mediator relating supervisor’s practices and employee’s innovative behaviour
Authors: Almazrouei Sultan Ali , Hilmi Mohd Faiz 
Published: December 2024

Purpose
Business environment, which is described by being volatile, uncertain, complex and ambiguous, forces organisations to innovate their products, processes and services to stay competitive. Employees’ innovative behaviours play a critical role in enhancing business environment. Therefore, this study aims to investigate the impact of supervisor’s practices on employee’s innovative behaviour and the mediating role of employee engagement on the relationship.

Design/methodology/approach
A quantitative research design was used. Data is collected from 163 employees from Ministry of Education in Oman by using an online questionnaire. SmartPLS-based structural equation modelling and process macro by Hayes are used for data analysis.

Findings
Results revealed significant relationships between supervisor’s practices (recognition, empowerment and development), employee engagement and innovative behaviour. It also revealed a significant relationship between supervisor’s practices (recognition, empowerment and development) and employee engagement. Furthermore, the results supported the hypotheses that supervisor’s practices affect innovative behaviour through employee engagement.

Originality/value
Although the literature reveals that supervisor’s practices foster innovative behaviour, the mediating role of employee engagement has rarely been empirically investigated. To the best of the authors’ knowledge, this paper is one of the first papers that asserts the importance of employee engagement in mediating the relationship between supervisor’s practices and employee innovative behaviour. It also investigates a hybrid of organisational (supervisor’s practices) and individual level factors (employee’s engagement) in predicting innovative behaviours. It contributes to a more comprehensive understanding of the ways to achieve a business strategy of innovation.

Authors: Gama Mariana Silva Barbosa , Bonamigo Andrei 
Published: December 2024

Purpose
In response to strict regulations, high customer pressure, climate change and scarcity of natural resources, manufacturers have reassessed their operation and performance strategies to balance the sustainability and competitiveness needed to pursue a long-term competitive advantage toward an endurable business. The purpose of this paper is to fill the gap between lean and sustainability, analyzing the sustainable lean manufacturing (SLM) effect on performance in the Brazilian automotive sector.

Design/methodology/approach
This study divided the performance into Triple Bottom Line (TBL) drivers: Economic, Social and Environmental, and developed six hypotheses for assessing the multidimensional performance of SLM organizations. Empirical data was collected with 127 usable responses, and the models were tested using partial least squares structural equations modeling. The results of this study are valid and adequate models and revealed that environmental, operational and social performance are significantly improved through SLM adoption in Brazilian automotive studies. In addition, analyze the interaction among the TBL’s drivers.

Findings
The results revealed positive and direct improvements in economic, social and environmental performance enhanced LM adoption. In addition, the results obtained in this study reveal that social drivers are more sensitive to prejudice due to simultaneous other driver improvements overlapping the workforce.

Originality/value
These findings are beneficial for company leaders and researchers working to improve the organization’s performance in these drivers, especially within companies in developing countries. These results explored different aspects of performance evaluation supporting a holistic view of the organization toward sustainability performance. Also explored different regulations and incentives for automotive companies that comply with specific sustainable goals.
Rapport in police interviews with victims: a linguistic comparison between UK and Spain
Authors: Gomez-Bedoya Maria 
Published: December 2024

Purpose
This study aims to explore how rapport is operationalised in police interviews with victims in the United Kingdom and Spain. Rapport is considered a key element in the success of investigative interviewing and therefore, police interviewers are trained to use rapport-building techniques throughout the interview. Previous research has enabled us to understand what rapport is and how it works in interviews with victims (Abbe and Brandon, 2012; Dando et al., 2016; Walsh and Bull, 2010). However, it has been highlighted that the expression of rapport may vary between cultures (Matsumoto and Hwang, 2021), as there are cultural and linguistic differences concerning interactional factors.

Design/methodology/approach
To uncover this, British and Spanish police interviewing guidelines are examined with regard to rapport techniques and how they are conceptualised. Then, a discourse-pragmatic and ethnographic approach is applied to real interviews with victims in the United Kingdom and Spain, to analyse what happens in real practice and how rapport with victims is expressed linguistically in British English and European Spanish.

Findings
The study unfolds certain linguistic subtleties in relation to “face-related issues” that need to be considered for future research on rapport in investigative interviews with victims, particularly in multicultural interviewing contexts.

Originality/value
The findings from this study contribute to a better understanding of how rapport is operationalised in different contexts and how the expression of rapport is tied to cultural and linguistic patterns that influence how people communicate.
The impact of diplomatic relations on corporate outward foreign direct investment: a spatial spillovers perspective
Authors: Yi Wenjun , Yang Yaru , Gu Lulu 
Published: December 2024

PurposeThis study aims to examine the spatial spillover effect and its mechanism of the impact of China–US relations on Chinese enterprises’ OFDI.Design/methodology/approachThis study takes the relations between China and the United States (China–US relations), one of the most important great power relations in the 21st century, as the research object, employing a spatial spillover perspective informed by bilateral and multilateral theory, information transfer theory and realism and institutionalism. This study utilizes micro-level data on Chinese firms’ outward foreign direct investment (OFDI) for 2008–2023 to study the spatial spillover effects and mechanism involved in the impact of China–US relations on Chinese firms’ OFDI.FindingsResults show that China–US relations increase Chinese enterprises’ OFDI in countries other than the US, demonstrating spatial spillovers in the impact of China–US relations on Chinese firms’ OFDI. This spatial spillover effect is characterized by a full cycle, time variation and imbalance. The mechanism analysis shows that this spatial spillover is realized through the neighboring country effects and great power demonstration effects. Heterogeneity analysis shows that firms’ independent research and development (R&D) capabilities, China’s economic power and the cultural distance between China and the host country can buffer the impact of changes in China–US relations on Chinese firms’ OFDI.Practical implicationsThis study provides a comprehensive understanding of the role of international relations in influencing OFDI and offers useful insights for developing countries to promote high-level opening-up.Originality/valueFirst, this study examines the spatial spillover effects of China–US relations on Chinese firms’ OFDI, expanding the perspective of the impact of diplomatic relations on cross-border economic activities. Second, this study enriches the research on the mechanism by which diplomatic relations affect OFDI by arguing that this spatial spillover is realized through the neighboring country effect and the great power demonstration effect. Third, this study confirms the role of enhancing the competitiveness of multinational corporations (MNCs), upgrading the country’s comprehensive national strength, and promoting cultural exchanges in buffering exogenous shocks of changes in China–US relations.
Differential impact of gender and academic background on complex thinking development in engineering students: a machine learning perspective
Authors: Suárez-Brito Paloma , Elizondo-Noriega Armando , Lis-Gutiérrez Jenny Paola , Henao-Rodríguez Carolina , Forte-Celaya María Rubi , Vázquez-Parra José Carlos 
Published: December 2024

Purpose
The purpose of this paper is to present the results of measuring a sample of engineering students’ perceived achievement of complex thinking at different stages of their professional training. This study intended to analyze and predict the differences in the self-perception of achieved complex thinking competency by gender, semester, course of study and high school of origin.

Design/methodology/approach
The methodology included applying the E-Complexity instrument to 225 university students from northern Mexico. The initial comparison of groups used the chi-square test and two supervised learning algorithms (logit regression with Lasso regularization and a classification tree).

Findings
The findings of this study indicated that the selected undergraduate degree did not reveal differences in self-perceived performance in complex thinking, while gender, semester and high school of origin had significant differences.

Research limitations/implications
Among the limitations of the study is the size of the sample and the fact that it only focused on engineering students from a single educational institution; however, this limitation responds to the exploratory nature of this study and the guidance of the institutional ethics committee. With these results, it is feasible to request an extension of the sample to include other disciplines to evaluate these findings, which, although relevant, cannot be considered exhaustive.

Originality/value
Regarding possible lines of research, the authors propose that given the difference between students who graduated from the high school of the same institution and those who did not, a possible line of research could explore new hypotheses on whether the policies and practices of the institution’s high school emphasize the development of complex thinking skills; the teachers of this high school are trained to teach complex thinking; and the learning materials of this high school are designed to develop complex thinking skills.

Authors: Fang Sipeng , Gong Zheqing , Chen Lijun 
Published: December 2024

Purpose
The purpose of this paper is that the long fluorocarbon monomer is used to modify the latex. The film of the resultant latex has the C-F bond with high bond energy and low surface energy, which can effectively improve the heat resistance and water resistance of the resultant film. In addition, a mixture of CO-436 and dibutyl maleate (DBM) as surfactants is used as the emulsifier, which brings the new application of the above surfactants.

Design/methodology/approach
The modified Vac-VeoVa10 copolymer nanometre latex modified VAc-VeoVa10 latex has been successfully synthesized via the semi-continuous seeded emulsion polymerization, which VAc and VeoVa10 is used as the main monomers and long fluorocarbon monomer was used as the functional monomer. Potassium persulphate (KPS) and the mixture of CO-436 and DBM were used as the initiator and emulsifier, respectively. The structure of resultant latex film was characterized by Fourier transform infrared spectroscopy (FTIR). The latex films were tested by thermogravimetric analysis, differential scanning calorimetry and contact angle. The particle size and its distribution of the latex were measured by the nano particle size analyzer.

Findings
Detailed investigation was conducted on the factors influencing the properties of the latex and film. The stability of the resultant latex is good. The average particles of the latex and its distribution are small and uniform, respectively. In comparison with the conventional latex film, the thermal stability and hydrophobicity of the resultant latex film are improved obviously.

Originality/value
The modification of p (VAc-VeoVa10) using a new emulsifier and long fluorocarbon monomer has not been widely reported. In this study, the modified Vac-VeoVa10 copolymer nanometre latex modified VAc-VeoVa10 latex has been successfully synthesized via the semi-continuous seeded emulsion polymerization, which VAc and VeoVa10 is used as the main monomers and long fluorocarbon monomer was used as the functional monomer. KPS and the mixture of CO-436 and DBM were used as the initiator and emulsifier, respectively.
