Aligned with the global commitment to Sustainable Development Goal (SDG) 12: Responsible Consumption and Production, this study investigated the role of mega events in promoting environmentally sustainable behaviors, with a specific focus on Expo 2020 Dubai.

The context of the current study is Expo 2020 Dubai. Data was gathered from a convenience sample of 250 Expo 2020 Dubai visitors, and following data screening, the data was analyzed using AMOS 24 software following a two-step approach.

The study found that the implementation of environmentally sustainable practices significantly explained visitors’ environmental sustainability awareness. Moreover, the implementation of environmentally sustainable practices and environmental sustainability awareness positively influenced visitors’ awareness of consequences. Personal norms were found to be influenced by environmental sustainability awareness and awareness of consequences, while the relationship between the implementation of environmentally sustainable practices and personal norms was found to be insignificant. Finally, all predictors of intention to adopt environmentally sustainable behaviors were significant, with environmental sustainability awareness having the strongest impact, followed by the implementation of environmentally sustainable practices, personal norms and awareness of consequences.

These findings contribute valuable insights into the potential influence of mega events on promoting environmentally sustainable behaviors, with implications for event organizers and policymakers working toward sustainable development objectives.

Despite the significant impact of mega-events, few studies have explored how their sustainability practices affect environmental awareness and behavior. With rising global concern for climate change, examining the role of events like Expo 2020 Dubai in promoting sustainability is crucial. This research addresses this gap by investigating how mega-events can enhance environmental awareness and sustainable behaviors.

Hotel management and academia are increasingly interested in corporate social responsibility (CSR) and charismatic leadership. In this context, the present study examines how charismatic leaders affect employee quality of life through CSR practices in hotels.

The survey encompassed employees working at either three-star or five-star hotels in Oman. The model was tested using data gathered from 396 hotel employees.

Results showed that charismatic leadership positively affects CSR-induced intrinsic and extrinsic attributions. CSR positively affected task significance and intrinsic quality and negatively affected turnover intention. Quality of life predictors had a considerable impact, with intrinsic quality and turnover intention standing out. There was no significant effect of task significance on quality of life. The relationship between charismatic leadership and CSR was stronger for employees in five-star hotels and weaker for employees in three-star hotels. The CSR role mediates the relationship between charismatic leadership and quality of life.

The results indicate that charismatic leaders exert a substantial impact on employees’ attributions of CSR. Upper-level management must emphasize fostering the cultivation of charismatic leadership attributes among non-charismatic leaders as a means to enhance employees’ perceptions of CSR.

Few studies have focused on analyzing employees’ perceptions of CSR activities on a micro level. Investigating CSR phenomena in the context of internal stakeholders, especially employees, is very rare.

It has been more than 20 years since the idea of binding multinational corporations directly to international law was abandoned. Since then, concerned actors have sought to manage corporate conduct through voluntary regulation. However, little is known about the instruments produced in this regard. This study aims to understand the properties of the instruments that govern or regulate corporate social responsibility at the international level.

Systematic literature review and content analysis methods were combined to compile a list of 229 international corporate social responsibility instruments (ICSRIs) produced by intergovernmental (IGOs) and international nongovernmental (INGOs) organizations. These instruments were categorized according to an adapted classification framework.

The majority of instruments from our sample are produced by INGOs, focus on management activities and are applicable to specific industries. The most common issues addressed by the instruments are related to worker protection, human rights, governance and the environment. A limited number of instruments specify stakeholders’ involvement or feature an external orientation. Instruments rarely address issues related to product quality and safety, economic contribution or social performance.

Without a comprehensive overview, it has been difficult to develop broad-based understandings about voluntary regulation as a mechanism for controlling corporate conduct internationally. This study’s findings offer valuable insights, allowing policymakers and industry practitioners to understand the effectiveness of, and make appropriate enhancements to, ICSRIs.

By enhancing ICSRIs to address the limitations highlighted in the current study, multinational corporations can be induced into contributing more productively to the sustainable development of the societies they impact and play a greater role in the realization of the Sustainable Development Goals.

Previous research has largely concentrated on analyzing small numbers of carefully selected instruments in a conceptual or descriptive approach. In contrast, this study represents a novel approach of systematic compilation and quantitative classification for a comprehensive list of ICSRIs.

Currently, the global hotel industry is faced with the challenge of a growing skills gap. Contrary to expectations, the shortage of skilled employees persists despite improved access to training. This implies that the cause of the shortage is not the lack of training, but a general lack of understanding of how training is transferred to practice. Therefore, this study aims to use an empirical approach to test a transfer of training (TOT) model that can be applied to the hotel sector.

The setting of the study is the Sultanate of Oman, and 302 questionnaires were collected from 24 hotel properties, of four- and five-star categories.

The findings reveal, to a high and significant degree, that the antecedents of TOT are the opportunity to perform (OTP) and motivation to transfer (MTT), while supervisor support is a significant moderator. In addition, motivation to learn (MTL) is the most important predictor of MTT, while accountability is the leading predictor of OTP. Results also indicated that perceived organizational support (OS) has the strongest impact on MTL.

The proposed model needs to be tested under different contexts, especially different countries and with different hotel categories, to determine if the relationships between the factors remain similarly valid. Other factors that can predict the TOT need to be investigated.

Practical recommendations for hotel operators have been presented, equipping industry practitioners with the tools they need to develop the competencies of their employees, thereby improving the performance of individual properties.

The current study emphasized the validity of the proposed training transfer framework which was adapted from the learning transfer system inventory model, highlighting the particular importance of factors such as perceived OS and accountability.

With recent advances in artificial intelligence, the hospitality industry has introduced the concept of unmanned smart hotels staffed by service robots instead of human employees. Research is needed to understand consumers’ receptivity to such an innovation. This paper examines factors associated with consumers’ potential resistance to using automated service hotels via two sequential studies. Given that younger generations of consumers are typically early adopters of advanced technology and innovative services, our sampling approach focused on this consumer group.

Two studies were conducted. Study 1 proposed and empirically tested a theoretical model. Results revealed that attitude, subjective norms and perceived behavioral control each positively influenced individuals’ intentions to use unmanned smart hotels. In Study 2, we further investigated aspects informing perceived security, a key variable in the use of unmanned smart hotels.

Findings showed how people’s beliefs about unmanned smart hotels and security control assurances led to perceived security. These perceptions were shaped by perceived physical risks, privacy concerns, website design and hotel reputation. Overall, this research provides theoretical and practical implications for various stakeholders associated with unmanned smart hotels.

Findings of this study suggested that managers of unmanned smart hotels should design user-friendly, secure processes and offer comprehensive support resources to enhance customer experience and usage.

The findings provide a holistic understanding of consumers’ receptivity to unmanned smart hotels.

The purpose of this paper is to evaluate the influence of nanoparticles as an additive on the tribological properties of calcium grease.

The nano additives in this research are with different concentration of multi carbon nanotubes (MWCNTs) and Talc powder (1, 2, 3, 3 and 5 per cent). The ratio of MWCNTs to Talc powder is 1:1. The tribological properties of hyper MWCNTs/Talc powder to calcium grease were evaluated using a pin-on-disk wear testing. The results show that the nano additives MWCNTs/Talc to calcium grease exhibit good performance in anti-wear and friction reduction. The action mechanism was estimated through analysis of the worm surface with x-ray diffraction and transmission electron microscope.

The result indicates that boundary film mainly composed of MWCNT and Talc powder, and other organic compound was formed on the worm surface during the friction test. In addition, the wear rate and coefficient of friction of nanogreases have shown excellent improvement about 80.62 and 63.44 per cent, respectively, at 4 Wt.% of MWCNTs/Talc powder. Moreover, the thermal conductivity of nanogrease increased about 51.72 per cent.

This study describes the inexpensive and simple fabrication of nanogrease for improving properties of lubricants, which improve power efficiency and extend lifetimes of mechanical equipment.

To enhance the tribological properties of nanogrease, one of the new technologies was used to synthesize a nanogrease having carbon nanotubes (CNTs) nanoparticles (NPs) with different concentrations. The microstructures of the synthesized NPs were characterized and evaluated by x-ray diffraction spectroscopy (XRD) and transmission electron microscopy (TEM). Tribological properties of the nanogrease were evaluated using a four-ball tester. The worn surface of four steel balls was investigated by scanning electron microscopy (SEM) and energy dispersive x-ray spectroscopy (EDX).

Grease was dissolved in chloroform (10 Wt.%), at 25 °C for 1 h. In parallel, functionalized CNTs with different volume concentrations (0.5, 1, 2 and 3 Wt.%) were dispersed in N, N-dimethylformamide. The mixture was stirred for 15 min and then sonicated (40 kHz, 150 W) for 30 min. After that, the mixture was added to the grease solution and magnetically stirred for 15 min and then sonicated for 2 h.

The results suggested that CNTs can enhance the antiwear and friction properties of nanogrease at 0.5 Wt.% CNTs to about 57 and 48 per cent, respectively. In addition, the weld load of the base oil containing 0.5 Wt.% CNTs was improved by 17 per cent compared with base grease.

This work describes the inexpensive and simple fabrication of nanogrease for improving the properties of lubricants, which improve power efficiency and extend lifetimes of mechanical equipment.

The purpose of this paper is to investigate the rheological characteristics of graphene nanoplatelets (GNPs) and hybridized nanocomposite consisting of multi-walled carbon nanotubes (MWCNTs) and GNPs as an additive on lithium-based grease. The experiments of nanogrease are examined in different values of shear stress, apparent viscosity, temperature and shear rate using Brookfield Programmable Rheometer DV-III ULTRA and characterized by high-resolution transmission electron microscope (HRTEM) and X-ray diffraction (XRD).

First, GNPs was mixed well with lithium grease using mechanical stirring at 3,500 rpm for 15 min at room temperature to form a homogenous composite at different concentrations (0.5, 1, 1.5, 2 and 2.5 Wt.%). Afterwards, MWCNTs and GNPs are mixed and dispersed well in the lithium grease using a sonication path for 30 min and mechanical stirring at 3,500 rpm for 15 min at 28°C to form a homogenous nanocomposite.

The results indicated that 1 Wt.% of GNPs is the optimum concentration. Subsequently, the weight percentage of additives varying between MWCNTs and GNPs are tested, and the result indicate that the grease containing GNPs had a 75 per cent increase in shear stress and 93.7 per cent increase in apparent viscosity over ordinary grease.

This work describes the inexpensive and simple fabrication of nanogrease for improving properties of lubricants, which improve power efficiency and extend lifetimes of mechanical equipment.

Virtual tourism has become popular in recent years. However, there is still a research gap on virtual tourist motivation. This study aims to identify virtual tourist motivation and explore the relationship between virtual tourism and on-site tourism.

This research identifies virtual tourist motivation based on Means-end chain (MEC) theory. Laddering interviews with 32 respondents were conducted to construct a hierarchical value map. Additionally, a motivation analysis of virtual tourism and on-site tourism was developed based on a review of the relevant literature.

This exploratory study revealed 12 attributes, 9 results and 4 values that virtual tourists wish to achieve and identified 5 means-end chains where self-satisfaction is the most important value-led motivation. Compared with on-site tourism motivations, virtual tourism shows possibilities of replacing, complementing and extending on-site tourism under certain circumstances. However, it significantly depends on whether tourists are attracted by the technical characteristics, security and experience conditions of virtual tourism.

This study contributes to understanding virtual tourist motivation and offers motivation-based insights into the relationship between virtual and on-site tourism. Managerial implications on how to attract potential online tourists are also provided.

虚拟旅游在近些年逐渐受到欢迎。然而, 关于虚拟旅游动机的研究仍存在不足。本研究旨在识别虚拟旅游动机, 并探讨虚拟旅游与现实旅游之间的关系。

本研究基于方法-目的链（MEC）理论识别虚拟游客动机。通过对32名受访者进行阶梯式访谈, 以构建一个价值阶层图。此外, 本研究在回顾相关文献基础上, 对虚拟旅游和现实旅游的动机进行差异化比较分析。

这项探索性研究揭示了虚拟旅游游客希望实现的12个属性、9个结果和4个价值, 并确定了5条MEC, 其中自我满足是最重要的价值导向动机。通过与现实旅游动机比较, 研究发现虚拟旅游在一定条件下具有替代、补充和延伸现实旅游的可能性。然而, 这在很大程度上取决于游客是否被虚拟旅游的技术特点、安全性和体验等条件所吸引。

研究结果有助于进一步理解虚拟旅游动机, 并为虚拟旅游和现实旅游之间的关系提供基于动机的见解。重要的是, 研究还为如何吸引潜在虚拟游客提供管理启示。

El turismo virtual se ha popularizado en los últimos años. Sin embargo, aún existe un vacío en la investigación sobre la motivación del turista virtual. El estudio pretende identificar la motivación del turista virtual y explorar la relación entre el turismo virtual y el turismo in situ (real).

Esta investigación identifica la motivación del turista virtual basándose en la teoría de la cadena medio-fin (MEC). Se realizaron entrevistas escalonadas a 32 encuestados para construir un mapa jerárquico de valores. Además, se elaboró un análisis de la motivación del turismo virtual y del turismo presencial basado en una revisión de la bibliografía pertinente.

El estudio exploratorio reveló 12 atributos, 9 resultados y 4 valores que los turistas virtuales desean alcanzar e identificó 5 MEC en los que la autosatisfacción es la motivación basada en valores más importante. En comparación con las motivaciones del turismo in situ (real), el turismo virtual muestra posibilidades de sustituir, complementar y ampliar el turismo in situ (real) en determinadas circunstancias. Sin embargo, depende en gran medida de si los turistas se sienten atraídos por las características técnicas, la seguridad y las condiciones de experiencia del turismo virtual.

Este estudio contribuye a comprender la motivación del turista virtual y ofrece perspectivas basadas en la motivación sobre la relación entre el turismo virtual y el turismo in situ (real). También se ofrecen implicaciones para la gestión sobre cómo atraer a los turistas potenciales en línea.

This introduction sets the scene for the study by explaining the rationale for presenting a comparative analysis of five nation states’ governance systems; England, Northern Ireland, Arabs in Israel, Trinidad and Tobago and the United States, with Nigerian interests represented in the research design. The context is that of a global phenomenon of a Black–White achievement gap (Wagner, 2010). The quality is world leading in terms of originality, significance and rigour. We present a theory of colonisation between groups with different interests, which includes nation states colonising other nation states, and dominant groups within nation states colonising marginalised groups. We also explored how dominant groups within educational governance systems may colonise marginalised groups within education governance systems. We theorised colonisation using Karpman’s Triangle (1968) identifying that different groups can be oppressor, and/or victim, and/or rescuer, and these roles may shift as changes occur in power and economic influence. We present the Empowering Young Societal Innovators for Equity and Renewal Model (Taysum et al., 2012, 2013, 2014, 2015, 2016, 2017) with five principals for equity and renewal. We explain the turbulence that senior-level leaders experience and how education governance systems need to empower their autonomy as credentialed educational professionals’ with track records of school improvement. Impact strategies to optimise students’ learning and students’ outcomes, and build the community’s values of social justice, courage and prudence need to underpin social mobility. These innovations are only possible if they are informed by grass roots participatory philosophical inquiry, that is informed by and informs policy, and is carefully monitored for quality assurance against the highest of educational professional standards.
