Abstract
Purpose
This study aims to investigate the moderating role of sociodemographic factors, specifically age and education level, in the knowledge-attitude-behavior (KAB) model concerning information security awareness (ISA) amid growing technological threats.
Design/methodology/approach
This study uses a survey methodology, collecting data from 400 working individuals in Vietnam, to test the applicability of the KAB model and evaluate the moderating effects of age and education on the model’s established relationships. In addition, the theoretical model and hypotheses were evaluated using the partial least squares structural equation model (PLS-SEM) approach.
Findings
This research confirms the relationships posited in the KAB model. Notably, it shows that younger employees showcase a more positive attitude and behavior toward information security compared with their older counterparts. In addition, higher education levels strengthen the positive association between information security knowledge and attitude. The findings underscore the imperative for organizations to consider sociodemographic variables when formulating strategies to enhance ISA.
Originality/value
This study extends the KAB model by exploring the impact of sociodemographic factors, focusing on age and education in ISA. Overcoming the oversight in current literature, particularly in the context of technological threats, the research uses PLS-SEM and targets a specific demographic in Vietnam.

Abstract
Purpose
This study aimed to utilize Epistemic Network Analysis (ENA) for a thorough evaluation of policy documents concerning the digital transformation in Vietnam's higher education sector.
Design/methodology/approach
Adopting a quantitative ethnography approach, this research employed ENA to analyse a curated collection of 21 documents that specifically addressed higher education (HE) and digital transformation within Vietnam. The study also incorporated qualitative content analysis, utilizing the constant comparison method as outlined by Onwuegbuzie et al. (2009), for data coding. ENA facilitated the examination of connections among various policy aspects.
Findings
The study revealed a consistent overarching theme in Vietnam's digital transformation policies during and post-pandemic, focusing on key areas such as ADMINISTRATION, VISION, QUALITY, and INFRASTRUCTURE. However, a temporal shift in emphasis was observed: during the pandemic, policies were more focused on ADMINISTRATION and INFRASTRUCTURE, while post-pandemic, there was an increased emphasis on COLLAB, VISION, and TEACH_LEARN.
Originality/value
This research represents one of the initial efforts to showcase the utility and significance of ENA in analysing policy documents. It underscores ENA's potential in elucidating the complex interplay of policy elements in the context of digital transformation in higher education, particularly within a developing country setting.

Abstract
Purpose
To achieve business success in a competitive market, hospitality firms are urged to search for different ways to enhance the firms' innovation capabilities. Drawing on dynamic capability theory, this study examined the role of entrepreneurial leadership in promoting product and process innovation through the mediating effect of innovation strategy and the moderating effect of knowledge acquisition.
Design/methodology/approach
Data were collected through a time-lagged (two waves, two months apart) survey from 137 managers and 322 employees working in 103 Vietnamese hotels. Structural equation modeling (SEM) was used to test the proposed hypotheses in our conceptual model.
Findings
The findings revealed that entrepreneurial leadership is positively associated with both product and process innovation. In addition, these relationships are mediated by innovation strategy. While the relationship between innovation strategy and product innovation is moderated by knowledge acquisition, evidence was not obtained for the moderation effect of knowledge acquisition on the link between innovation strategy and process innovation.
Originality/value
The findings advance innovation and leadership literature by identifying the roles of entrepreneurial leaders in managing an organization as a dynamic system and developing appropriate innovation strategy to adapt to rapidly changing environments. In addition, this study offers important implications for hospitality firms that are investing in innovation activities and are seeking ways to promote the firms' innovation of products and processes.

This study aims to enhance to corrosion protection of NiZn-plated steel by electroplating multilayer coating.
Abstract
Purpose
This study aims to enhance to corrosion protection of NiZn-plated steel by electroplating multilayer coating.
Design/methodology/approach
The multilayer coating consists of three layers on mild steel substrate, such as Cr3+ chromate conversion layer (CCC), electrodeposited nanosilica zinc-nickel composite layer (ZnNiSi) and electrodeposited zinc-nickel alloy layer (ZnNi). Its morphology, composition and corrosion behaviour were investigated by various methods.
Findings
Polarization curves indicated that polarization resistance and corrosion current density of CCC/ZnNiSi/ZnNi/Fe (6.956 kO.cm2; 2.56 µA.cm−2) were two times higher and five times lower than that of ZnNiSi/ZnNi/Fe (3.42 kO.cm2; 12.52 µA.cm−2), respectively. From electrochemical impedance spectroscopy data, charge transfer resistances were 1.344, 2.550 and 2.312 kO.cm2 for ZnNi, ZnNiSi/ZnNi and CCC/ZnNiSi/ZnNi, respectively. Salt spray test indicated that after 48 h, surface of ZnNi and ZnNiSi was covered by white rust, whereas no white rust was observed on surface of CCC/ZnNiSi/ZnNi. After 600 h, there were red rust spots (1% surface coverage) on surface of Zn-Ni, whereas only white rust was observed on both ZnNiSi/ZnNi (100% surface coverage) and CCC/ZnNiSi/ZnNi (10% surface coverage).
Originality/value
Multilayer coating enhanced significantly the corrosion protection for steel, as compared to the single-layer coating.

Abstract
Purpose
The aim of this empirical study is to investigate an integrated model that captures the way service quality of banking kiosks (BK-SQ) exerts its impacts on customer perceived value and customer satisfaction and the moderating mechanism of technology readiness (TR) in the quality–satisfaction relationship in the banking sector in Vietnam.
Design/methodology/approach
An offline survey was conducted to obtain responses from 604 users of banking kiosks in Vietnam. Exploratory factor analysis, confirmatory factor analysis and structural equation modeling were used for data analysis. The moderating effect of TR was examined following the product indicator method.
Findings
The results validate significant positive correlations between BK-SQ, customer perceived value and customer satisfaction. Among six service quality dimensions, convenience is the most significant factor in predicting perceived service quality. The study also delineates how TR can moderate the link between service quality and customer satisfaction.
Research limitations/implications
Future studies may make further attempts to incorporate other human and demographic factors as a moderator into the research model.
Practical implications
Bank managers should strive to improve the operations of banking kiosks based on six aspects and increase TR levels of customers to boost customer satisfaction with banking kiosks.
Originality/value
The study contributes to the literature on service quality and self-service technologies (SSTs) by offering critical insights into how banks can make use of influence mechanisms in the model to enhance service quality and customer satisfaction.

Abstract
Purpose
This paper aims to explore how research and development (R&D) scientists and engineers can contribute to sustainability initiatives in their organisations.
Design/methodology/approach
This paper uses a critical case study methodology, focussed on a large Vietnamese company in which business leaders sought to engage R&D scientists and engineers in sustainability initiatives focussed on eco-innovation and eco-efficiency. Bourdieu’s theoretical lens of habitus, capitals and field facilitates a relational analysis of the findings.
Findings
While R&D scientists and engineers adapted well to early changes aligned with eco-innovation, they struggled to engage with sustainability initiatives in the case firm. This study explains adaptions and constraints as scientists and engineers’ professional habitus and capitals, and their broader organisational field.
Practical implications
This paper provides insight into how organisations might integrate professional acculturation and appropriate facilitators to promote the additional contribution of scientists and engineers to sustainability initiatives in the context of an organisation.
Social implications
Although eco-innovation and eco-efficiency are only potential dimensions of comprehensive organisational sustainability reform, this research provides insight into how engaging scientists and engineers with a broader social sustainability agenda might be advanced.
Originality/value
The study addresses calls for empirical insights into ways that scientists and engineers can commit to organisational sustainability practices based on the configurations of habitus, capital and organisational field.

Abstract
Purpose
This study aims to explore how the inhibitor-loaded nanocontainers can be used in the epoxy coating for protection of steel against corrosion. A self-healing anticorrosive coating can be easily fabricated by embedding the inhibitor-loaded nanocontainers into the epoxy coating matrices. For this purpose, first, cerium (a catholic corrosion inhibitor) is encapsulated into silica nanoparticles (SiO2@Ce). Thereafter, an epoxy nanocomposite coating has been prepared on steel substrate using these SiO2@Ce nanoparticles as nanofillers.
Design/methodology/approach
To examine the effect of SiO2@Ce nanocontainers on mechanical properties of epoxy coating, the abrasion resistance, impact resistance and adhesion strength of coating have been evaluated. To reveal the effect of SiO2@Ce nanocontainer on corrosion behavior of epoxy-coated steel, the electrochemical impedance spectroscopy (EIS) has been conducted in NaCl solution.
Findings
Transmission electron microscopy and scanning electron microscopy/Energy-dispersive X-ray spectroscopy analyses indicate that Ce3+ cations have been successfully loaded into the surface of silica nanoparticles (at the content of approximately 2 Wt.%). Mechanical tests of epoxy nanocomposite coatings indicate that the nanocomposite coatings with nanoparticles content of 2.5 Wt.% provide the highest values of abrasion resistance, impact resistance and adhesion strength. EIS results show that the presence of SiO2@Ce3+ nanocontainers increases both coating resistance and polarization resistance. Along with the improvement the coating barrier performance, Ce inhibitor plays an important role in improving the anticorrosive performance at the steel–electrolyte interface.
Originality/value
The application of self-healing epoxy/SiO2@Ce nanocomposite coatings for the protection of carbon steel is very promising.

This study aims to examine service quality in Nigerian general hospitals and determines possible differences in service quality perceptions between employees and patients.
Abstract
Purpose
This study aims to examine service quality in Nigerian general hospitals and determines possible differences in service quality perceptions between employees and patients.
Design/methodology/approach
Using the Servqual scale, data was collected from 328 employees and patients of two government hospitals in Abuja and Delta states. Analysis was carried out using SPSS 26 package for constructs reliability frequency, mean, standard deviation and t-statistics.
Findings
The study found significant differences in the perception of service quality between employees and patients of the Nigerian general hospitals. While employees gave a high rating to empathy, patients rated it low. Also, the patients’ poor perception of tangible did not match the employees’ high perception. Other specific findings are patients’ unfavourable assessment of the physical facilities and judged the staff to lack professional dressing. Patients felt the hospitals could not provide necessary equipment for their procedures and thus considered their services unreliable.
Practical implications
Reliability was perceived as a significant problem in this study; therefore, the hospitals management should ensure correct diagnoses and treatment results of the highest quality and timely services. Also, the management should invoke strong relationships between the employees and patients to earn patients’ trust. Employees should ensure to listen to patients’ complaints and find solutions promptly. Patients need health-care workers’ support and rely on their abilities; Therefore, health-care workers should be highly dependable and show empathic behaviour in discharging their duties. Health-care managers must access employees‘ and patients’ particular perceptual gaps and reconcile the difference before further quality improvement initiatives.
Originality/value
The findings in this study strengthen the clamour for assessing service quality from both employees and patients’ views in public hospitals. Hospital service quality is complex and primarily judged from the patients’ perspective. This study showed that health-care quality means different things to all stakeholders.

Abstract
Purpose
This paper aims to explore how entrepreneurial culture (EC) and psychological empowerment (PE) support innovative work behaviour (IWB) of employees in organizations. First, it examines the impact of EC on IWB. It also explores the mediating effect of PE to support the EC – IWB relationship. Accordingly, it suggests a mechanism model to explain the relationship between EC and IWB.
Design/methodology/approach
This is an empirical research using quantitative methods. Data were collected via both face-to-face and online surveys from 308 employees in Vietnamese enterprises. The partial least squares-based structural equation modelling (PLS-SEM) approach was applied to test hypotheses in the research model.
Findings
Significant R-square values were achieved for both EC – PE and PE – IWB relationships, according to the PLS-SEM. The most interesting finding is the full mediating role of PE in the relationship between EC and IWB. Despite the non-significance in the direct impact of EC on IWB, the role of EC in promoting IWB is important in an indirect way through PE. The significant role of PE in facilitating IWB has been proven.
Originality/value
This research is one of the initial attempts to empirically build the roadmap from EC, as a typical type of organizational culture, through the mediating effect of PE to improve IWB. This roadmap provides top managers with a hierarchical view that effectively cascading interventions from the organizational level, such as EC, through a significant mediator as PE at the group level, and then down to IWB as a result at the individual level.

Abstract
Purpose
This paper aims to investigate the impact of the COVID-19 pandemic on university students' employability skills and give insights into preparation for future crises that may happen.
Design/methodology/approach
Employing an interpretative phenomenological approach with the frame of social cognitive theory, the current study examined the changes in environmental, behavioral and personal elements of human functioning for employability skills being affected by the conditions during the pandemic.
Findings
Findings based on ten in-depth semi-structured interviews with students at universities in Vietnam highlighted that the global pandemic performed as both challenge and an opportunity for employability skills development, yet the extent to which the students can benefit from the new studying conditions attributed to each individual's initiatives in taking advantages of resources and acting against difficulties.
Originality/value
Whether the pandemic became a hindrance or a motivation for students' employability skills to develop and whether students effectively utilized an agency to overcome challenges and improved their skills after the pandemic have not yet been investigated. This study added to the body of literature regarding self-regulated learners by demonstrating agency in the learning process as well as how to manage careers and improve employability skills by making use of resources in disconnected settings.
