Abstract
Purpose
This paper aims to offeri novel nano-additives polymer microgels to precisely improve the lubrication properties of titanium alloy under different temperatures.
Design/methodology/approach
The surfactant-free emulsion polymerization method was used to prepare Poly(N-isoprolylacrylamide) (PNIPAM) microgels. A ball-on-disk tribometer was applied to investigated the temperature-sensitive lubrication behavior of PNIPAM microgels.
Findings
The results show that the as-prepared microgels are ball-like nanoparticles with the size of 50–900 nm. In addition, potassium persulfate as initiator, complete mixing technic and high sodium dodecyl sulfate (SDS) concentration contribute to the formation of microgels with small size. The tribosystem shows a lower friction coefficient with the lubrication of PNIPAM microgels as aqueous solution additives when the temperature exceeding the critical temperature.
Originality/value
This work reports the temperature-sensitive lubrication of PNIPAM microgels. The critical temperature of PNIPAM microgels could be regulated by the addition of SDS in the solutions. This offers an effective and facile strategy for regulation of the critical temperature of smart microgels, which is helpful for the smart lubrication in the future.

Abstract
Purpose
Image congruence is one central metrics that significantly influences image transfer. Nevertheless, studies on impact of image congruence on consumers' attitudinal and behavioral components in the context of sport tourism remain few. Therefore, this study aims to investigate the relationship among image congruence between sport event and host city, spectators' attitude toward the event and city and their intention to revisit and recommend the event and city. A mediating role of attitude in the relationship between image congruence and behavioral intention was also examined.
Design/methodology/approach
The study selected non-local spectators of the F1 Chinese Grand Prix and Shanghai ATP Masters 1000 as the participants. A total of 491 valid questionnaires were obtained from the survey of two events, including 222 from F1 Chinese Grand Prix and 269 from Shanghai ATP Masters 1000. Among respondents, 360 were Chinese spectators from other regions (73.3%) and 131 were international spectators (26.7%). The data were analyzed via descriptive statistics, correlations, factor analysis, exploratory factor analysis (EFA), confirmatory factor analysis (CFA), hierarchical regression analysis and ANOVA.
Findings
The results showed that image congruence between sports event and host city had a positive impact on spectators' attitude toward and intention to recommend the city; but it had no significant impact on attitude toward event, intention to revisit and recommend the event and intention to revisit the city. Attitude toward event had a positive impact on intention to revisit and recommend the event, and attitude toward host city had a positive impact on intention to revisit and recommend the city. In addition, attitude toward host city fully mediated the relationship between image congruence and intention to recommend the city.
Originality/value
The current study provides a meaningful contribution to the existing literature by examining the impact of image congruence on spectators' attitudinal and behavioral components in the context of sport tourism.

Abstract
Purpose
An increasing number of Chinese enterprises are involved in cross-border mergers and acquisitions (M&As). However, few Chinese enterprises have achieved successful integration, which plays a critical role in enhancing performance. The important field of cultural integration is currently facing major challenges. To identify the reasons for these challenges, studies have analyzed why cultural integration succeeds or fails and have suggested that cultural differences between acquiring and acquired enterprises are the primary obstacles to cultural integration. However, it is unclear how success can be achieved. The paper aims to focus on cultural integration from the perspective of acculturation to describe the penetration of cultural elements in M&As.
Design/methodology/approach
In adopting acculturation as our theoretical lens, the authors use the case study method to answer the following research question: “how can the cultural integration of Chinese enterprises be successfully achieved?” Two typical cases are examined: Lenovo’s cultural integration with IBM’s personal computer (PC) division and Haier’s cultural integration with Sanyo home appliance. First, using the exploratory case study method, the Lenovo–IBM PC division case is analyzed. The characteristics and relationships between cultural environments, employee adoption methods and acculturation patterns are summarized to reveal a cultural integration path. Second, the Haier–Sanyo home appliance case is analyzed using the confirmative case study method to test the findings of the Lenovo–IBM PC division case.
Findings
The results indicate that it is critical to achieve a dynamic fit between cultural environments, employee adoption methods and acculturation patterns during each stage of cultural integration (exploration, experimentation, reinforcement and fixing). The three constructs of these stages reflect the following evolutionary paths: “isolate-introduce-learning-chance taking”, “detecting-icebreaking-interacting-remodeling” and “specialized sections-senior managers-managers-employees”.
Originality/value
These findings contribute to the development of cultural integration and acculturation theories and serve as a reference for Chinese enterprises wishing to implement cultural integration strategies.

Abstract
Purpose
Although both sports and cities have transformed over the last century, research on the intersection of sports and urban development remains scarce. This special issue was designed to advance a research agenda in relation to sports and urban development. The sports and urban development special issue of International Journal of Sport Marketing and Sponsorship brings together a collection of conceptual, empirical and commentary papers from four continents. Themes explored in this special issue include legacy, governance, image, climate change and sustainability. We encourage collaborative approaches between sport researchers and those with a focus on urban development, urban design and urban governance. Understanding the role of sports in the development of smart cities is an excellent opportunity for these collaborations to occur.
Design/methodology/approach
A comprehensive review of literature was undertaken to assess the literature related to sports and urban development.
Findings
In addition to this introductory article, there are ten manuscripts selected for this special issue investigating sports and urban development.
Originality/value
This special issue seeks to promote more research on sports and urban development, ultimately ultimately advancing theories and providing solutions.
