Abstract
Purpose
The purpose of this paper is to argue that large executive compensation can be one of the reasons why so many chief executive officers (CEOs) are overconfident. It also discusses the implications of this finding for boards and human resource directors.
Design/methodology/approach
The research investigated how overconfidence – an overestimation of ability – affects how hard people work to win an elimination contest. These kinds of contests exist in the workplace where employees strive for a senior position or CEO role. The study involved a two-stage contest with four players. The first stage consists of two semi-finals. The two semi-final winners move on to compete in the second stage, the final. Overconfident players overestimate the impact of effort on their probability of winning at each stage. Each player is deemed the same, aside from their confidence levels. Finally, the study assumes an overconfident player’s bias is observable by rivals.
Findings
Overconfident individuals can have the highest chance of winning elimination contests compared to more rational rivals. When executive pay is high, and overconfidence is not too extreme, they exert more effort than their rational rivals in the semi-finals. High executive pay, or in this case, prize money, is more appealing to overconfident individuals because they think they are more likely to win the bigger prize money in the final. This can be likened to people’s careers. High executive pay incentivises overconfident employees more and they exert more effort early in their careers to achieve this.
Originality/value
To the best of the authors’ knowledge, this is one of the first studies to measure the impact of overconfidence on elimination contests, providing a new explanation for why overconfident employees often reach CEO positions. This has implications for how HR practitioners should manage overconfident and rational employees, including the effort they deliver to a business.

Abstract
Purpose
The effect of hotel employee safety behavior has not as yet been investigated. The purpose of this research is to determine the impact of hotel employee ternary safety behavior on negative safety outcomes, as well as the moderation effects of job vigor and emotional exhaustion.
Design/methodology/approach
A questionnaire survey of 16 medium- and high-star-rated hotels in southeast China was conducted and 571 responses were received for model estimation. The statistical analysis techniques adopted were confirmatory factor analysis, correlation analysis, hierarchical regression, and structural equation modeling.
Findings
The results showed that: (1) safety compliance and participation positively predicted safety adaptation; (2) the three dimensions of safety behavior contributed to reducing negative safety outcomes, and there was a multiple mediation process in their relationship; and (3) job vigor positively moderated the influence of safety compliance and adaption on negative safety outcomes, and emotional exhaustion negatively moderated the influence of safety participation on negative safety outcomes.
Originality/value
This research provides greater insights into the relationship between safety behavior and outcome performance within the hotel industry, and yields theoretical and practical implications for improving employee safety behavior and hotel safety performance.

Abstract
Purpose
This paper aims to realize an in-situ quality inspection system rapidly for new injection molding (IM) tasks via transfer learning (TL) approach and automation technology.
Design/methodology/approach
The proposed in-situ quality inspection system consists of an injection machine, USB camera, programmable logic controller and personal computer, interconnected via OPC or USB communication interfaces. This configuration enables seamless automation of the IM process, real-time quality inspection and automated decision-making. In addition, a MobileNet-based deep learning (DL) model is proposed for quality inspection of injection parts, fine-tuned using the TL approach.
Findings
Using the TL approach, the MobileNet-based DL model demonstrates exceptional performance, achieving validation accuracy of 99.1% with the utilization of merely 50 images per category. Its detection speed and accuracy surpass those of DenseNet121-based, VGG16-based, ResNet50-based and Xception-based convolutional neural networks. Further evaluation using a random data set of 120 images, as assessed through the confusion matrix, attests to an accuracy rate of 96.67%.
Originality/value
The proposed MobileNet-based DL model achieves higher accuracy with less resource consumption using the TL approach. It is integrated with automation technologies to build the in-situ quality inspection system of injection parts, which improves the cost-efficiency by facilitating the acquisition and labeling of task-specific images, enabling automatic defect detection and decision-making online, thus holding profound significance for the IM industry and its pursuit of enhanced quality inspection measures.

Abstract
Purpose
This paper aims to present wireless passive temperature sensors by using high-temperature stable polymer-derived silicoaluminum carbonitride (PDC-SiAlCN) ceramic materials.
Design/methodology/approach
In this paper, a novel PDC-SiAlCN ceramic was synthesized by using polyvinylsilazne and aluminum-tri-sec-butoxide as precursors. Then, PDC-SiAlCN was used as the sensing material to fabricate sensors. The sensors are based on a cavity resonator and an integrated slot antenna. The resonant frequencies of the sensors are determined by the dielectric constants of PDC-SiAlCN ceramic, which monotonically increase versus temperature.
Findings
The effect of sensor dimension on the performance of the sensors was investigated using simulation and experimental methods. The using temperature, reliability and sensing distance of the sensors were studied experimentally. The sensors performed measurement up to 1100°C with excellent reliability and repeatability. The sensing distance varied from 38 to 14 mm when the temperature increasing from 20°C to 1100°C.
Originality/value
PDC-SiAlCN ceramic based wireless passive temperature sensors have the advantage of seamless integration of slot antennas and resonators, which greatly reduces the size of the sensor, reduces the direction of antenna transmission and increases the transmission space. The sensors can be used for many harsh environment applications such as engine monitoring.

Abstract
Purpose
The purpose of this paper devoted to the application of modal analysis to analyze the flow structure of trailing edge cutback film cooling and the effects of vortex structure on the film cooling effectiveness of the cutback surface.
Design/methodology/approach
Large eddy simulation (LES) is used to simulate the trailing edge cutback film cooling. The results of LES are analyzed by proper orthogonal decomposition (POD) method and dynamic mode decomposition (DMD) method. The POD method is used to determine the dominated vortex structure and the energy level of these structures. The DMD method is used to analyze the relationship between vortex structures and wall temperature.
Findings
The POD method shows that the flow field consists of three main vortices – streamwise vortex, lip vortex and coolant vortex. The DMD results show that the lip vortex mainly acts on the middle section of the cutback surface, while the streamwise vortex mainly acts on the back section of the cutback surface.
Research limitations/implications
The modal analysis is only based on numerical simulation but the modal analysis of experimental results will be further studied in the future.
Practical implications
This paper presents the powerful ability of the modal analysis method to study complex flows in trailing edge cutback film cooling. Establishing the relationship between vortex and wall temperature by modal analysis method can provide a new idea for studying convective heat transfer problems.
Originality/value
The role of streamwise vortex in the flow of the trailing edge cutback cooling and its effect on the cooling effectiveness of the cutback surface is found.

Abstract
Purpose
Williams and Williams (2012, 2017) find multiple entrepreneurial motivations are experienced by entrepreneurs in deprived areas at different points in time. Drawing on this prior work this study aims to explore how and why the shifted motivations evolve, as well as, what factors cause this change in deprived areas. The work draws upon temporal motivational theory (TMT) that considers the influence of individuals' needs in determining their time-sensitive motivation.
Design/methodology/approach
Six semi-structured interviews with actual entrepreneurs are used to collect qualitative data from deprived areas of Nottingham, which is one of the most deprived cities in the UK. The study employs Interpretative Phenomenological Analysis (IPA) to consider each entrepreneurial endeavour as a unique journey to investigate the shifting of motivations.
Findings
A polarization is found in terms of how entrepreneurial motivations evolve in deprived areas. In considering the first task-specific entrepreneurial motivation, time plays a role either in accumulating job dissatisfaction and increasing confidence led by accumulated experience, or in creating random chances that enable individuals to realize that they are able to use existing skills and experiences to start a business. Regarding the second task-specific entrepreneurial motivation when the business becomes more established, it is usually stimulated by increased confidence based on perceived progress. The use of self-help methods and downward comparison found in this study should be noted as they help to re-consider individuals' needs in deprived areas.
Originality/value
This study produces a more comprehensive understanding of the phenomenon of the time effect on shifted motivation at different entrepreneurial phases in a deprived context, which contributes to enrich theoretical knowledge and raise policymakers' awareness of entrepreneurial motivations from these marginalized groups.

Abstract
Purpose
The purpose of this paper is to show how to obtain a supercapacitor with high specific power (P) and high specific energy (Ep) simultaneously.
Design/methodology/approach
The carbon aerogels are obtained by ambient pressure drying method instead of supercritical drying method and carbon aerogels/Ni(OH)2 composites are prepared by in situ polymerisation. A series of asymmetric supercapacitors based on carbon aerogels/Ni(OH)2 composites as positive electrode and activated carbon as negative electrode, respectively, are assembled. The electrochemical performances of carbon aerogels/Ni(OH)2 composites and supercapacitors are studied.
Findings
The results show that the specific capacitance (CP) of carbon aerogels/Ni(OH)2 composites is 584 F/m2. The working potential of supercapacitors could be increased to 1.6V. When the mass ratio of carbon aerogels and Ni(OH)2 is 3:7, the mass ratio of positive electrode and negative electrode is 1:1, the EP and P of the supercapacitor is higher than 10.5 Wh/kg and 578 W/kg, respectively, when the current varies from 50 mA to 100 mA and the attenuation ratio of CP is only 8.3 per cent after 10,000 cycles at 100 mA.
Practical implications
The supercapacitors can be used in the field of automobile engineering and can solve the problems of energy shortage and environmental pollutions.
Originality/value
The supercapacitor based on carbon aerogels/Ni(OH)2 composites as positive electrode and activated carbon as negative electrode is novel and the synthetic properties of the supercapacitor are excellent.

Abstract
Purpose
This paper aims to reveal the green governance role played by stock connect in transition economies from the perspective of corporates’ environmental violations and provides implications for the coordination and optimization of subsequent stock market liberalization and green transformation policies in pursuit of carbon peaking and carbon neutrality goals.
Design/methodology/approach
With the data of Chinese listed enterprises, this paper takes the Shanghai-Hong Kong Stock Connect or Shenzhen-Hong Kong Stock Connect in China as a quasi-natural experiment and applies the multi-period difference-in-difference (DID) model to identify the impact of stock market liberalization on the corporates’ environmental violations.
Findings
The findings reveal that the stock market liberalization significantly restrains the corporates’ environmental violations. These findings are robust to a series of sensitivity tests, including excluding two-way effects, adjusting the year of policy implementation, replacing the core variables, introducing the regional fixed effects and excluding the interference effect of other relevant policies during the sample period. Furthermore, the stock market liberalization is beneficial for upgrading information disclosure quality, improving internal governance capability, strengthening environmental protection incentives, and thus restrains corporates’ environmental violations. Meanwhile, heterogeneity tests show that the inhibitory effects are more significant in those grouped samples which is large scale, state-owned nature, located in eastern region, with poor evaluation performances and heavy tax burden.
Originality/value
We make two marginal contributions to the current literature. First, this paper enriches the literature on the factors influencing corporate environmental violations by focusing on how the macro-level financial policy influences the micro-level corporate environmental violations. One the one hand, prior studies mainly focused on the consequences of corporate environmental violations; however, there is still a puzzle that the effect of stock market liberalization cannot be fully justified to influence corporate environmental violations. The findings help explain this puzzle by examining that stock market liberalization can restrain corporate environmental violations. Moreover, prior studies mainly focused on corporate share price (Yunsen Chen et al., 2022), market liquidity (Han Kim and Singal, 2000), information disclosure (Liang, Lin, and Chin 2012), corporate governance (Bae and Goyal, 2010) and corporate violations (Lingyun Xiong et al., 2021), but not on corporate environmental violations. We assume that the suppression effect of stock market liberalization on corporate environmental violations can help reduce corporate environmental violations, improve corporates’ awareness of environmental compliance. Second, this paper contributes to a better understanding of the literature on stock market liberalization by investigating the restraining effect of Stock Connect on corporate environmental violations from the perspective of information channel, corporate governance channel and motivation channel, which is of practical significance. Moreover, we investigate the differences in the inhibitory effects of stock market liberalization on different enterprises' environmental violations, from firm size, property rights, enterprise assessment results, tax burden to geographical location, which is conducive to the construction of a green financial system and the promotion of sustainable economic development. Our results show that firms which are large scale, state-owned nature, located in eastern region, with poor evaluation performances and heavy tax burden tend to compliance with environmental laws. These findings emphasize the importance and benefits of Stock Connect.

Abstract
Purpose
This paper aims to examine the day-to-day within-person associations between employees' flow experience and organizational identification within the rarely studied context of construction engineering project organizations.
Design/methodology/approach
In this daily diary design, the authors surveyed 204 (Mage = 28.3, SD = 5.69) employees of a state-owned construction engineering project organization in southwest China via the online questionnaires comprising flow and organizational identification scales once daily on each workday for three consecutive weeks, which yielded 3,060 data entries. The authors then tested the temporal directionality between flow and organizational identification with multilevel time-series cross-lagged path analysis using Mplus 8.3.
Findings
Daily flow experience was linked positively with same-day organizational identification. Importantly, flow experience on the previous day predicted organizational identification on a subsequent day, but not vice versa.
Practical implications
This study suggests that construction engineering project managers should implement interventions fostering the employees' flow experience to promote organizational identification, with important implications for organizations aiming at flourishing workforces by facilitating organizational identification through implementing flow strategies.
Originality/value
There is a dearth of diary studies on flow and organizational identification specific to construction engineering project employees. The authors’ findings provide concrete evidence of the fluctuant nature of daily flow experience and organizational identification as well as their dynamic predictive pathway relationship.
