Electronic government procurement is an important platform that promotes efficient, transparent, competitive and agile delivery of procurement activities in public sector organisations. Implementing units who play a major role exhibits different attitude towards new technology. The purpose of this paper is to assess if there is any significant difference between optimistic and discomfort implementing units in relation to the implementation and intention to use the Ghana Electronic Procurement System (GHANEPS).

Technology Readiness, Technology Acceptance and Unified Theory of Acceptance and Use of Technology and Diffusion Innovation Theory constituted the theoretical foundation. Guided by a cross sectional survey design, quantitative data from a sample of 181 procurement officers was collected using structured questionnaires. The hypothesised relationships were analysed using partial least squares structural equation modelling (PLS-SEM).

Although there were some observable differences, the bootstrap results show that the difference was not significant, implying that these two groups do not differ much about the GHANEPS introduction and implementation. This is justifiable in the case of Ghana because public policies are made by top officials, and those in the grassroot or implementation domain have no choice but to act accordingly.

This study focused on metropolitan, municipal, district assemblies, public hospitals, tertiary institutions and senior high schools.

The study contributes to the critical antecedents for electronic procurement implementation and public sector management literature. It provides public institutions and practitioners with empirical evidence on how beliefs and perceptions of implementing units about electronic public procurement has some influence on attitude towards usage and intention to use. Positive attitudes and perceptions of the public procurement officers can be reinforced through adequate training and awareness creation.

This study outcomes can serve as philosophical underpinnings for societal development.

This study used a multi-group analysis to examine if there is any significant difference between these two categories of implementing units (optimistic group and discomfort group) in relation to facilitating conditions, personal innovativeness, perceived usefulness, perceived ease of use and ultimately to attitude and intention to use GHANEPS.

This study aims to investigate Vietnamese hotel workers’ use of national stereotypes in cross-cultural service encounters. The study extends the existing knowledge on service failures and recovery attempts by illustrating how national stereotypes could inform these decisions through the lens of the script theory.

In this qualitative study, 34 service providers were interviewed about their experience in dealing with guests from different countries in Vietnamese hotels.

Service providers categorised guests based on their countries of origin to predict their behaviour prior to guest arrivals. When the guest’s behaviour matches the expectations, the service encounters went smoothly by following existing scripts. If there is a discrepancy between the guest behaviours and expectations, it could lead to service failure and the need for new scripts. Appropriate interventions in this process could turn anecdotes into accumulated understanding of guest behaviour for better service and guest experience as a new application of national stereotypes.

This study advances cross-cultural service encounter research by integrating national stereotypes and script theory. It sheds new light on how national stereotypes could inform service delivery and recovery attempts in service organisations.

本研究旨在调查越南酒店员工在跨文化服务遭遇中使用民族刻板印象的情况。研究通过脚本理论的视角阐释了国家的刻板印象如何为这些决定提供信息, 扩展了现有的服务失败和恢复尝试的知识。

在这项定性研究中, 采访了34家服务提供商, 了解他们在越南酒店与来自不同国家的客人打交道的经历。

本研究通过整合民族刻板印象和脚本理论, 推进跨文化服务遭遇研究。它揭示了在服务组织中, 国家的刻板印象如何影响服务提供和恢复尝试。

Este estudio tiene como objetivo investigar el uso de los estereotipos nacionales por parte de los trabajadores hoteleros vietnamitas en el encuentro intercultural de servicios. El estudio amplía el conocimiento existente sobre los fallos en el servicio y los intentos de recuperación al ilustrar cómo los estereotipos nacionales podrían influir en estas decisiones a través de la teoría del guion.

En este estudio cualitativo, se entrevistó a 34 proveedores de servicios sobre su experiencia en el trato con huéspedes de diferentes países en hoteles vietnamitas.

Los proveedores de servicios clasificaron a los huéspedes en función de sus países de origen para predecir su comportamiento antes de su llegada. Cuando el comportamiento de los huéspedes coincide con las expectativas, los encuentros con el servicio se desarrollaron sin problemas siguiendo los guiones existentes. Si hay una discrepancia entre los comportamientos y las expectativas de los huéspedes, podría provocar un fallo en el servicio y la necesidad de nuevos guiones. Las intervenciones consideradas apropiadas en este proceso podrían convertir las anécdotas en una comprensión acumulada del comportamiento de los huéspedes, lo cual mejoraría el servicio y la experiencia de los huéspedes como una nueva aplicación de los estereotipos nacionales.

Este estudio avanza en la investigación de encuentros de servicio interculturales mediante la integración de estereotipos nacionales y la teoría del guion. Además, arroja nueva luz sobre cómo los estereotipos nacionales podrían influenciar la prestación de servicios y los intentos de recuperación en las organizaciones de servicios.

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.

This study, which utilizes the job demands-resources (JD-R) theory, aims to explicate the relationship between responsible leadership (RL), green behavior (GB) and the mediating role of voice behavior (VB).

This study used a quantitative research design. The research sample consists of 260 participants who work in five-star hotels in Izmir. The research data were collected through face-to-face and online survey methods. Confirmatory factor analysis (CFA) in AMOS was performed to assess the measurement model. The research hypotheses were tested with structural equation modeling (SEM).

The results determined that RL affects GB and VB positively and significantly. In addition, VB has a significant positive link with GB. Furthermore, this study discovered that VB acts as a mediator in the relationship between RL and GB, indicating that RL indirectly promotes GB through implementing VB.

This study has limitations, such as its dependence on self-reported data, cross-sectional design and exclusive emphasis on participants from a single nation. When RL encourages employees to take GB, they are more likely to engage in GB. This study contributes to the field by evaluating the structures discussed with the JD-R theory. In the management practice of organizations, RL should be strengthened, and training should be provided to enhance RL.

The literature analysis revealed that, while studies have been undertaken using RL, the idea has not been tested using VB or has it been investigated in the hotel business, which has grown vital to the global economy. With these aspects, the work stands apart and serves as a source of motivation for researchers.

To provide a holistic assessment of tourists’ staycation intentions, this study aims to investigate the role of secondary-stakeholder corporate social responsibility (CSR) on local engagement. Based on construal-level theory and stimulus-organism-response model, this study unpacks how and when secondary-stakeholder CSR influences staycation intention.

Data were gathered from 312 Chinese tourists with prior staycation experiences. Data were subsequently analyzed using structural equation modeling.

This study illuminates that secondary-stakeholder CSR positively influences staycation intention directly and indirectly through psychological belonging and safety. Noteworthily, immersive experience strengthens the influence of psychological belonging on staycation intention while its effect on the relationship between psychological safety and staycation intention is negligible.

All variables in this study were collected via self-report measures provided by hotel customers with staycation experiences. Although both statistical and procedural remedies are used, it would be more useful if future studies could gather time-lagged and/or multiple sources of data.

This study augments the domain of staycation research by examining CSR marketing through a stakeholder perspective. This nuanced analysis elucidates the intertwined dynamics among secondary-stakeholder CSR, psychological sense of belonging and safety, and immersive experiences that delineate the landscape of staycation markets, casting light on their epoch-defining implications for hotels’ developmental trajectories.

Emergence of COVID-19 has posed a big challenge around the world demanding responsible behavior at all levels for effective mitigation of its adverse effects on humanity. Despite deadly nature of the pandemic, people yet tend to violate the lockdowns, social distancing, and related protective measures. This study presents a critical view and identifies underlying causes of the deviant behavior of masses. It highlights specific areas where responsible leadership can make a difference in fighting the pandemic from organizational perspective.

Qualitative data collected through in depth interviews from three different countries - Pakistan, Turkey and Malaysia. The data was collected thrice with time lags and integrated view has been presented in this study.

The study finds that perceptual dissonance, cost of protective behavior, reactive attraction and perceived triviality of protective measures are some of the main causes of deviant behavior.

Although the data have been collected from three countries, yet smaller sample size remains a limitation of the study. Similarly, the longitudinal data was collected once in each wave of COVID-19 and its increased frequency could make findings more reliable.

The findings provide an “analysis template” for responsible leaders to analyze any crisis situation in future. In the light of findings, leaders can locate causes of deviant behavior and the way they can influence behavior of employees in a crisis.

The study is highly valuable in analysis of social dimension of COVID-19 crisis at organizational level. It clearly highlights the significance of social and financial support by responsible leaders for influencing the protective intentions of employees in an emergency situation.

The organizational perspective and the responsibilities of leaders for fighting the pandemic has not been adequately explored. This study has investigated the likely causes of deviant behavior of employees in adoption of protective measures. It also highlights the areas where responsible leaders can make a difference in inducing protective behaviors.

Three-dimensional (3D) printing technologies have gained attention in dentistry because of their ability to print objects with complex geometries with high precision and accuracy, as well as the benefits of saving materials and treatment time. This study aims to explain the principles of the main 3D printing technologies used for manufacturing dental prostheses and devices, with details of their manufacturing processes and characteristics. This review presents an overview of available 3D printing technologies and materials for dental prostheses and devices.

This review was targeted to include publications pertaining to the fabrication of dental prostheses and devices by 3D printing technologies between 2012 and 2021. A literature search was carried out using the Web of Science, PubMed, Google Scholar search engines, as well as the use of a manual search.

3D printing technologies have been used for manufacturing dental prostheses and devices using a wide range of materials, including polymers, metals and ceramics. 3D printing technologies have demonstrated promising experimental outcomes for the fabrication of dental prostheses and devices. However, further developments in the materials for fixed dental prostheses are required.

3D printing technologies are effective and commercially available for the manufacturing of polymeric and metallic dental prostheses. Although the printing of dental ceramics and composites for dental prostheses is promising, further improvements are required.

This paper examines the impact of Russian invasion of Ukraine on the intraday efficiency of four major energy markets, namely, diesel oil, Brent oil, light oil and natural gas.

This study applies the multifractal detrended fluctuation analysis (MFDFA) to high-frequency returns (30-min intervals) for the period from October 21, 2021, to May 20, 2022. The data sample of 5,141 observations is divided into two sub-samples, before and after the invasion of 24th February 2022. Additionally, the magnitude of long memory index is employed to investigate the presence of herding behavior around the invasion period.

Results confirm the presence of multifractality in energy markets and reveal significant changes of multifractal strength due to the invasion, indicating a decline of intraday efficiency for oil markets. Surprisingly, the natural gas market, being the least efficient before the invasion, turns out to be more efficient after the invasion. The findings also suggest that investors in these energy markets are likely to show herding, more prominently after the invasion.

The multifractal patterns, in particular the long memory property of energy markets, can help investors develop profitable investment strategies. Furthermore, the improved efficiency observed in the natural gas market, after the invasion, highlights its unique traits and underlying complexity.

This study is the first attempt to assess the impact of the Russia–Ukraine war on the efficiency of global commodity markets. This is quite important because the adverse effects of the war on financial markets may potentially cause destabilizing outcomes and negative effects on social welfare on a global scale.

The Department of Architecture at the University of Pretoria is working in the South African housing context while gaining knowledge of such issues worldwide. Various innovations are being carried out in terms of housing design and delivery methods in South Africa. Through a methodical approach to design, it is believed that future architects will be able to answer to contextual needs without compromising the high standard of design expected by the Department.

This paper evaluates an exercise in open building principles, carried out in 2003, with post−graduate architecture and interior architecture students at the University. The focus was the application of open building principles from the urban design level to that of the building and the residential units. It involved the design of social housing and the upgrading of existing workers’ hostels into family units as well as the provision of social amenities. Students were to design various types of housing, showing alternative ways of ‘living’ and study housing in the area. The project involved close interaction with community representatives.

The area of study was located in Soshanguve, a township with predominantly black inhabitants, situated to the northwest of Pretoria. The previous political dispensation designated specific areas on the outskirts of the city as locations for black migrant workers, known as townships. Subsequently these townships have become cities in themselves, housing a large portion of the total population of Pretoria. It is here that there is a need for urban development and social housing.

Soshanguve offered an excellent opportunity for learning and the dissemination of good design principles in housing design. A debate on the relevance of open building to South Africa has been initiated. It is concluded that open building systems are an effective tool to achieve diversity and can accommodate for wider sectors of the population.
