This study aims to understand how the assembly of rotating ring affects the axial forced vibration of gas face seals.

A three-mass kinematic model is established to investigate the axial movement of the rotating ring with bilateral constraints. The separation, collision and frictional sliding of the rotating ring in sleeve are discussed under rotor excitation. The effects of operating parameters and O-ring dynamic characteristics on the separation degree and film thickness disturbance are analyzed. A dimensionless axial characteristic force is defined to determine the critical conditions for the occurrence of separation. Several effective methods to eliminate the separation are proposed based on the adjustment of typical installation parameters.

Under rotor excitation, there may be two collisions between the rotating ring and the sleeve surfaces in one excitation period. This will cause self-excited vibration of the fluid film, increasing the risk of seal failure. The separation and collision can be prevented by increasing the equilibrium ratio, the installation radius of the O-ring on the outer surface of the rotating ring and the friction in the sleeve.

The results develop the modeling of multibody dynamics of gas face seals, enabling more accurate prediction of vibration characteristics.

This paper aims to examine the congruency effects of physically embodied robots in service encounters, which addressed a significant research gap concerning the synthesis of robot design elements (e.g., appearance and voice) and their service purposes.

Grounded in congruity theory and human-robot interaction literature, this study conducted a pretest and two experimental studies revealing the need to view robot design holistically and recognizing the pivotal role of congruity in shaping consumers’ service robot adoption. The moderating role of service purposes (utilitarian vs hedonic) was also investigated in terms of robot design and consumer reactions.

Consumers generally tend to favor robots with congruent designs, particularly for utilitarian service purposes. The serial mediation through perceived congruence and perceived intelligence explains such a favorite tendency.

This study advances service robot design research by highlighting the critical role of congruity in enhancing consumer engagement. It supports the use of comprehensive, congruent designs for services with utilitarian purposes and recommends adaptable designs for hedonic settings.

This study addressed the research gap by examining service robot design from a holistic perspective. The research findings highlight the importance of congruency effects in service robot design and deployment and provide valuable insights and guidelines to industry practitioners for optimal investment in service robots.

International experience has long been recognized as a crucial determinant for firms’ knowledge management in the existing literature. However, within a global context, the relationship between international experience and the performance of multinational enterprises is intricate and remains ambiguous. While the impact of people mobility has been extensively studied, limited understanding exists regarding how global mobility of people and evolving external environments reshape the relationship. This study aims to integrate existing empirical evidence on this relationship and examines the contingencies posed by environmental factors.

This study conducted a multilevel meta-analysis based on a sample of 231 effect sizes collected from 167 articles to systematically examine the international experience–performance relationship, considering the moderating effect of the global mobility of people and the rise of national sentiments (including authoritarianism and protectionism). A two-stage procedure comprising Hedges-Olkin-type meta-analysis and random-effects meta-analytic regression was adopted.

The findings demonstrate a predominantly positive international experience–performance relationship that varies across studies owing to differences in research design, variable measurements and firm characteristics. The relationship is positively moderated by the global mobility of people, yet the positive effect is contingent upon the level of national sentiments within home countries. The beneficial effect of inbound mobility on this relationship is attenuated by authoritarianism and protectionism, while the effect of outbound mobility is positively influenced by authoritarianism and less affected by protectionism.

This study offers novel theoretical insights into multinationals’ knowledge accumulation in the internationalization process. It contributes to the existing literature by presenting an integrated framework elucidating the international experience–performance relationship. Building upon the knowledge-based view, it integrates environmental dynamics and national sentiments to investigate the performance implications of multinationals’ international experience, thereby providing valuable practical insights for effective global knowledge management.

Online brand communities (OBCs) and their role in determining consumer behavior is gathering interest of theorists and practitioners. This study examines the role of OBCs in influencing the level of involvement leading to perceived sport team brand equity (STBE) of sports fans from a social exchange theory perspective. The role of self-congruity as a moderator is examined to determine the differences in the level of involvement and attachment of fans in OBCs.

Based on quantitative research and convenience sampling, data for the study were collected from 394 football fans who were existing members of OBCs. The research model is tested using partial least square structural equation modeling.

The results show a direct and significant impact of brand involvement on brand attachment. Consumer brand engagement (CBE) mediates the relationship between brand attachment and STBE. While self-congruence does moderate the effects between brand involvement and brand attachment.

The study reveals the role of community related factors on sports fans’ perceived STBE. The study also provided a novel approach to examine sport fan behavior in social media through the lens of social exchange theory. Finally, it is providing a novel approach in examining role of OBCs in influencing behavior of sports team fans towards the team and brand.

The appearance of social media in small and medium enterprise (SME) business operations seems to be increasing in recent years. SME owners have started to understand that digital marketing tools can benefit their businesses significantly. Hence, in this study, we explore further the relationship between organisations and customers, and how SMEs use social media as an opportunity to develop their enterprises. We report the results by relying on qualitative methods to explore the insights from a wider stakeholder perspective. The findings contribute to the existing literature in agreement with the latest theories that SMEs in Greece are aware of the hidden opportunities and try to apply branding with the combination of social media. This study explores further the role of electronic word of mouth (eWOM) in a business transition, customers' experience and competitive business advantage.

It has been ten years since the policy was implemented, but the effect of the policy needs to be tested empirically. This paper aims to explore the mechanism of policy influence on regional innovation ability by measuring the effectiveness of policy by innovation ability indicators. Further, it reflects the problems in the process of the transformation and development of resource-based cities in recent years and points out the direction for the development of the cities in the future. In addition, this paper discusses the differences between regions and cities in China and seeks the path to narrow the gap.

This paper mainly uses the difference-in-difference method for the research. This study divided China’s resource-based cities and non-resource-based cities into experimental groups and control groups, and explored the effect of the transformation and development of resource-based cities and the changes of their innovation ability under the influence of the National Sustainable Development Plan for Resource-based Cities (NSDPRC). More carefully, this paper uses the fixed effects regression model, propensity score matching method, bootstrap method and other methods to improve the empirical results.

This paper finds that NSDPRC significantly improves the innovation ability of resource-based cities, although there is some lag in this effect. Research on the influence mechanism of policies shows that NSDPRC improves the marketization degree of resource-based cities and reduces the proportion of the secondary industry in such cities. Finally, the results of the heterogeneity analysis confirm that policies are more popular in western China and that resource-based cities in growth, maturity and decline are more vulnerable to policy influence. The development of policy effectiveness also requires the size of a city, and maintaining a healthy and reasonable scale is necessary for urban development.

First, the existing research on the development of resource-based cities is mainly from the perspective of economy and environment, but rarely from the perspective of innovation ability, and the index to measure urban development is relatively single. This paper will compensate for this deficiency. Second, different from the European and American countries that have basically completed the industrial transformation, the research on Chinese cities will provide a reference for the transformation of developing countries. Finally, from the perspective of resource endowment theory and innovation theory, this paper discusses the influence of SDPNRBC mechanism on the innovation ability improvement of resource-based cities, and further improves and enriches the theory.

Waste generation poses a significant environmental challenge in the United Arab Emirates due to the rapid urbanization, population growth and industrialization witnessed in recent decades. As a result, there has been a substantial surge in waste production. To fulfil its sustainability and circular economy aspirations in various economic domains, the UAE must prioritize efficient waste management. The purpose of this study is to assess the environmental and energy efficiency of the UAE’s economic sectors particularly within its vital energy sectors, which encompass crude oil, natural gas and mining, manufacturing and electricity, by gauging their adherence to sustainability and circularity objectives.

The authors used the data envelopment analysis input–output model to identify sectors that exhibit strong performance as well as those that are falling behind.

Based on this study, the agriculture, the crude oil, natural gas and mining sectors and financial services and banking were found to be the most efficient. The results of this study concluded that the UAE is making progress toward achieving its sustainability and circularity objectives; however, the findings suggest that more effort is needed to fully realize these goals.

By identifying high-performing and underperforming sectors, decision-makers can prioritize efforts to enhance sustainability and circularity in area of greatest need in the economy.

This study examines the influence of organizational culture types, specifically clan, adhocracy, hierarchy and market culture, on innovative capability and a firm’s international growth orientation within Brazil’s wine industry.

The paper builds on empirical evidence gathered from responses of managers from 230 Brazilian winemaking organizations based on a self-administered survey. The hypotheses in the conceptual model are tested using Smart-PLS (partial least square).

The types of culture that showed a positive relationship with dynamic innovation capability were clan, adhocracy, and market. Regarding the orientation for international growth, the market culture is the most conducive. Clan culture is not ideal for internationalization, and both adhocracy and hierarchical cultures showed no relationship. It was found that dynamic innovation capability has a positive relationship with the orientation for international growth.

The study broadens the research perspectives for analyzing resources from the Brazilian wine industry, further examining their linkage with the orientation for the international growth of the segment. The findings provide managers with insights about which types of culture should be fostered when aiming to innovate and internationalize.

The advancements are related to the Sustainable Development Goals advocated by the United Nations.

The study is motivated by the lack of integrated methodologies that relate organizational culture, dynamic innovation capability and orientation for international growth. International business research has neglected to specify which particular resources a company needs to have a propensity for international growth orientation.

With the increasing use of robots in service scenarios in hospitality industries, service failure frequently occurs during the service process, and consumers may react differently toward humanoid vs. nonhumanoid robots due to different performance expectancies. This study focuses on consumers' reactions to service failures by humanoid vs. nonhumanoid robots and the different impacts on brand forgiveness and revisit intentions through performance expectancy for different genders.

The study used a sample of 280 participants to test the moderated chain mediation model. The participants were instructed to report their performance expectancies for humanoid/nonhumanoid robots and imagine a hotel check-in scenario in which a service failure occurs. Brand forgiveness, brand revisit intention and other demographic information were assessed.

The results show that consumers have higher performance expectancy for nonhumanoid robots. This performance expectancy generates brand forgiveness and revisit intentions for male consumers but does not affect female consumers' forgiveness and revisit behaviors.

This study contributes to the literature by taking a long-term perspective to investigate the outcomes after service failure, providing evidence for pending questions in previous studies and enriching studies of gender differences. Additionally, this study provides practical implications to consider the use of anthropomorphism in robots, advocate for functional confidence in robots and target consumers across genders.

This study aims to identify the strategic factors and their effects on the post-cross-border acquisitions (CBA) technological innovation performance of the acquiring firms. It develops a hierarchical model to examine the interrelationship between identified strategic factors such as strategic flexibility, strategic ambidexterity, environmental dynamism, etc.

This study uses modified total interpretive structural modeling qualitative methodology (m-TISM) to develop a hierarchical model and conducts a Matrice d’impacts croisés multiplication appliquée á un classment (MICMAC) analysis to show the interrelationship between strategic factors affects the acquirer’s post-CBA technological innovation performance. It determines the autonomous, dependent, linkage and independent strategic factors. It further uses comparative case analysis to empirically examine the strategic factors in real-time CBA situations.

This study shows the m-TISM-based hierarchical model highlighting the interrelation, level of autonomy, dependence and linkage among strategic factors affecting the acquirer’s post-CBA technological innovation performance. It suggests that strategic factors such as environmental dynamism, R&D competence, innovation capability and technological capability are largely autonomous and have significant driving power, whereas strategic ambidexterity and strategic flexibility are the connecting factors. post-M&A integration is the governing factor for technological innovation performance in CBA.

The strategists and practitioners could evaluate the key strategic factors having significant driving power for strategy formulation and implementing efficient policies. By implementing the m-TISM model acquiring a firm’s post-CBA performance can be enhanced. Future researchers might utilize quantitative methods like regression and structural equation modeling in the CBA context.

This study uses a novel m-TISM and MICMAC approach to identify the driving and dependent factors affecting post-CBA technological innovation performance. It further provides a detailed theoretical and conceptual understanding relating to the philosophy and establishes an interrelation amongst these under-researched strategic factors in CBA.
