This paper describes an experimental and numerical study at elevated temperatures on the behaviour of full scale composite floor cellular steel beams with circular and elongated web openings. A total of three specimens, comprising three different steel geometries and loading conditions were tested at elevated temperatures. Finite element models were established with both material and geometrical non-linearity to compare with the experimental results. This paper also demonstrates the capability of a developed simple design approach in comparison with numerical modelling, experimental tests and existing design software used by the Steel Construction Institute (SCI).

This paper presents a numerical study to predict the in-fire performance of slim floor system, composed of asymmetric steel beam, deep steel decking and in-situ concrete slab. The reliability of the proposed numerical model was verified by comparison with experimental results obtained for 4.2m beam tests. A pilot study was also conducted to examine the effect of the cross sectional modification of the steel section on performance enhancement of the model in fire.

The purpose of the study was (1) to examine the motivational composites determining consumers' continued intention to use digital ticketing via self-service technology (SST) by integrating service satisfaction and (2) to ascertain the differences between consumers according to their psychological discomfort toward technology.

Data were collected using a structured questionnaire, and a total of 323 were included in the analysis. Partial least squares structural equation modeling (PLS-SEM) was utilized to test motivational determinants of digital ticketing. In addition, permutation-based multi-group analysis was performed to investigate the differences between consumers with high and low technology discomfort.

Both intrinsic and extrinsic motivation are positive predictors of continued intention to use digital ticketing, but only intrinsic motivation has a positive impact on continued intention through service satisfaction. Moreover, the relationship between intrinsic motivation, service satisfaction and continued intention was stronger for consumers with high psychological discomfort than those with low psychological discomfort.

Given the conspicuous characteristics of the digital ticketing process for sporting events, the insights gained from the study may be of assistance to researchers and practitioners in understanding sport consumers' ticket consumption behavior and the determinants of SST usage.

The purpose of this study is to (1) identify the factors that affect the adoption of virtual reality (VR) for spectator sports, (2) examine the differences in the factors among the four adopter categories (i.e. continuers, discontinuers, potentials and resistors) and (3) determine whether these factors are useful for discriminating among the adopter categories, based on the “diffusion of innovation” and “uses and gratification” theories.

In total, 216 participants were included in the analysis. Logistic regression and multiple analyses of variance were conducted to identify the factors that affect the adoption of VRS and examine the differences in the factors between adopter and non-adopter as well as between the continuers, discontinuers, potentials and resistors.

This study found that actualized innovativeness, complexity, companionship and gender significantly affect user adoption of VR for spectator sports. There were significant differences in the factors among the four adopter categories. The factors were also useful in discriminating between the four adopter categories.

This study highlights how individuals embrace emerging technologies differently based on their adopter category characteristics. From a marketing perspective, the insights gained from this study can inform the development of targeted strategies, campaigns and user experiences for VR spectator sports (VRS). This approach promises new revenue streams for the spectator sport industry and offers solutions to challenges like declining viewership and digital marginalization. It underscores the potential success of VR technology in transforming the spectator sport industry.

Despite the negative effects of toxicity on various aspects of esports communities, gamers continue to enthusiastically show their pride and engage with the game. Based on the stress and coping theory, the current study aims to shed light on how esports gamers cope with toxicity to develop toxicity tolerance by the mediation effect of positive reappraisal coping strategy.

A total of 456 gamers were included in the analysis. Structural equation modeling was performed to evaluate the hypothesized model. Gender differences in the toxicity-coping process were investigated using multi-group analysis.

The findings revealed the full mediation effect of positive reappraisal on the relationship between toxicity and toxicity tolerance, especially for male gamers. The empirical evidence of this study contributes to theorizing the transformative role of positive reappraisal in developing positive consumption outcomes when esports gamers experience toxicity in the game. The multi-group analysis provided further insights into differentiating the applicability and effectiveness of positive reappraisal based on gender.

The findings contributed to sport management and communication literature by allowing researchers and practitioners to move beyond a preventive coping mindset by facilitating a positive coping environment that encourages gamers to interpret the conversation and messages in a more positive manner.

The purpose of this paper is to investigate the effect of laser peening (LP) on mechanical and wear properties of 304 stainless steel sheet.

Three-dimensional morphology, micro-hardness and micro-structure of shocked samples were tested. The wear amount, wear track morphology and wear mechanism were also characterized under dry sliding wear using Al₂O₃ ceramics ball.

The LP treatment generates deformation twins that contribute to the grain refinement and hardness increase. The wear test displays that the wear mechanism of samples is mainly abrasive wear and oxidation wear at 10 N load. While at 30 N, the delamination and adhesion areas of treated sample are reduced visibly compared to untreated ones.

This study specifically investigates the mechanical and wear properties of 304 stainless steel after the direct action of LP on its surface, which shows an effective improvement on the wear resistance. For example, the wear loss of processed sample is reduced by 19% at 30 N, the friction coefficient decreases from 0.4714 to 0.4308 and the groove depth is reduced from 78.1 to 74.4 µm under same condition.
