Abstract
Purpose
This study aims to investigate the effects of hotel customers’ perceived utilitarian and hedonic values on their intention to use service robots. In addition, the influences of innovativeness, ease of use and compatibility on hotel customers’ perceived utilitarian and hedonic values were examined.
Design/methodology/approach
The data of the current study was collected from 11 countries including the USA, UK, Turkey, Spain, Romania, Japan, Israel, India, Greece, Canada and Brazil. A structural equation modeling was used to test the study hypotheses.
Findings
The results indicated that hotel customers’ intention to use service robots was positively influenced by their utilitarian and hedonic value perceptions. In addition, customers’ perceptions of robots’ ease of use and compatibility had a positive impact on their perceived utilitarian and hedonic values.
Originality/value
The findings of the current study provide unique contributions in the context of hospitality robotics technology adoption literature. In addition, this study provides valuable insights and novel opportunities for hospitality decision-makers to capitalize on, as they strive to strategize the integration of robot-based services into their operations.

Abstract
Purpose
The purpose of this paper is to examine the dynamic of consumers' perceptions of GM food and explore whether their knowledge of GM technology is associated with a significant change.
Design/methodology/approach
This paper presents a meta-analysis of 156 primary studies reporting a total of 225 attitudes toward genetically modified foods. To identify the impact of consumers' knowledge of GM technology, the authors estimate multivalued treatment effects model.
Findings
The results of this study show that consumers' attitudes show a U shape during 2001–2022. That is, the rise in opposition to genetically modified foods has been reversed. In addition, this study also shows that the increase in consumers' knowledge of genetically modified technology contributes to their changes in attitude.
Originality/value
This paper is the first study that empirically investigates the dynamics of Chinese consumers' attitude to genetically modified foods, and shows the rise in opposition to genetically modified foods has been reversed, which has important implication for commercialization of genetically modified crops in China.

Abstract
Purpose
This study aims to investigate the surface modification on 20CrMnTi gear steel individually treated by diamond-like carbon films and nitride coatings.
Design/methodology/approach
For this purpose, the mechanical properties of a-C:H, ta-C and AlCrSiN coatings are characterized by nano-indentation and scratch tests. The friction and wear behaviors of these three coatings are evaluated by ball-on-disc tribological experiments under dry contact conditions.
Findings
The results show that the a-C:H coating has the highest coating-substrate adhesion strength (495 mN) and the smoothest surface (Ra is about 0.045 µm) compared with the other two coatings. The AlCrSiN coating shows the highest mean coefficient of friction (COF), whereas the ta-C coating exhibits the lowest one (steady at about 0.16). The carbon-based coatings possess excellent self-lubricating properties compared with nitride ceramic ones, which effectively reduce the COF by about 64%. The major failure mode of carbon-based coatings in dry contact is slight abrasive wear. The damage of AlCrSiN coating is mainly adhesive wear and abrasive wear.
Originality/value
It is suggested that the carbon-based film can effectively improve the friction-reducing and wear resistance performance of the gear steel surface, which has a promising application prospect in the mechanical transmission field.
