High-nitrogen steel is a common material for the manufacture of drilling equipment such as drill collars. However, its poor surface properties often limit its applications. The purpose of this paper is to find a way to enhance the surface performance of high-nitrogen steel, which is expected to improve the wear resistance of high-nitrogen steel.

The CoCrNi and CoCrFeNi medium-entropy alloy (MEA) coatings were prepared on high-nitrogen steel substrate by laser cladding technology. The microstructure, phase composition and element distribution of the fabricated coatings were investigated using scanning electronic microscopy, electron backscatter diffraction and X-ray diffraction. The phase structure, phase stability and structural stability of the CoCrNi and CoCrFeNi MEAs were investigated in combination with phase diagram calculation and molecular dynamics. Then the wear tests were carried out for coatings.

The results show that both prepared MEA coatings have good quality and contain a single face-centered cubic phase. The wear performance of MEA coatings is improved by the refinement of grain size and the increase of dislocation density. Due to the addition of Fe atoms, the lattice distortion of the CoCrFeNi system increased, resulting in a higher dislocation density of the coating. Cr atoms in the CoCrFeNi system are the largest, and the local lattice distortions induced by them are greater. Through this study, MEA coatings with high hardness can be expanded to drilling field applications.

CoCrFeNi and CoCrNi MEA coatings were successfully prepared on the surface of high-nitrogen steel for the first time without obvious defects. The micromorphology and grain orientation of the different kinds of coatings were discussed in detail. The hardness-strengthening mechanism and structure stability of the coatings were illustrated by experiments and molecular dynamics simulations.

Achieving project performance goals in extremely resource-constrained environments, such as those of social enterprises, is challenging. These organizations often employ bricolage – making the most of available resources – to navigate challenging landscapes. This study aims to understand how bricolage capabilities enhance or attenuate organizational project outcomes in resource-constrained social enterprises.

An exploratory survey was conducted to understand project management practices in Canadian social enterprises. Established scales were used to measure constructs with confirmatory factor analysis, and linear regression was employed to analyze relationships.

The study provides empirical evidence of the positive influence of bricolage on organizational project performance, with a crossover interaction observed for moderators – entrepreneurial leadership and project management capabilities. While project capabilities strengthen the positive impact of bricolage capabilities on project performance, entrepreneurial leadership has the opposite effect.

The insights from this study offer an initial roadmap for project managers for effective resource acquisition and utilization through bricolage, ultimately enhancing project management effectiveness in resource-constrained environments.

Despite the crucial role of bricolage capabilities in resource-constrained environments, the project management literature has largely neglected this concept. It is unclear how organizations use bricolage to manage projects. This lack of understanding challenges organizations, hindering their ability to apply bricolage consistently and thoughtfully in managing projects. Our study provides a deeper understanding of how bricolage facilitates project performance and enriches our understanding of it as an effective resource mobilization strategy within social enterprises.

This study aims to cross-validate the technology experience (TE) scale and examine the potential differences in consumer TE across three different sectors.

Across three separate studies, the TE scale and its psychometric properties and consequences were examined across three distinctive hospitality and tourism (H&T) sectors: accommodations (n = 640), food and beverage (n = 615) and tourism (n = 592).

The findings consistently show that TE is a second-order formative construct with nine dimensions. Furthermore, the factor structure of consumer TE is consistent across the focal sectors, enhancing the TE scale’s generalizability. While the dimensions consisting of TE were identical across the three sectors, the composites of TE were formed differently across the sectors, demonstrating the differences in consumers’ TE across the three sectors.

This research offers practical implications to the H&T industry regarding the different impacts of various TE dimensions on consumers’ overall experiences, thereby creating overall satisfaction and behavioral intentions.

To the best of the authors’ knowledge, this research was the first attempt to examine the differences in consumers’ TE across the sectors of the H&T industry. By identifying the different impacts of TE dimensions on consumers’ overall experience, this research provides theoretical and practical contributions by confirming the distinct characteristics of the sectors under the H&T industry.

Digital entrepreneurship is a highly topical, sub-specialist and contemporary branch of entrepreneurship which is providing ever-increasing range of platforms for pursuing entrepreneurship-related career options. While the academic discourses in this area are increasingly growing, there is an equal level of scant attention paid to inquire how proclivity toward this career choice is developed and influenced. In the present study, this gap has been addressed by identifying major antecedents of digital entrepreneurship intentions under the aegis of capital theory.

Using the survey data from 287 respondents, structural equation modeling was utilized to explore the association of four antecedents: digital entrepreneurial competence, innovative cognition, social media adroitness and digital entrepreneurship role models on the goal intentions. Subsequently the association between goal intention and implementation intention to start a digital venture was also examined.

The analysis confirms the significant impact of the identified antecedents on the digital entrepreneurial volition of potential entrepreneurs. Our results demonstrate that innovativeness has the greatest impact on the goal intentions to create new digital ventures followed by the presence of role models. Digital competence is also a significant contributor in enhancing the propensity to start digital ventures while being digitally adroit has the least impact on such inclination. Lastly, our study provides empirical evidence to the linkage between goal and implementation intentions.

This paper informs practice on entrepreneurship education especially the role of skill-based education programs to enhance the information technology–related knowledge of students and incubation support for hands-on-training on the various dimensions of digital ventures. At policy-level institutions providing entrepreneurial education can design special tasks and learning activities that are focused on acquainting students with design thinking perspectives and lean start-up approaches.

This study aims to investigate the relationship between employees' exposure to supervisor incivility and their engagement in insubordinate behavior, by detailing a mediating role of ruminations about interpersonal offenses and a moderating role of supervisor task conflict.

The research hypotheses were assessed with three rounds of data, obtained from employees and their peers, working for firms in various industries.

An important reason that employees' sense that their supervisor treats them disrespectfully escalates into defiance of supervisor authority is that the employees cannot stop thinking about how they have been wronged. The mediating role of such ruminations is particularly prominent when employees' viewpoints clash with those of their supervisor.

A critical danger exists for employees who are annoyed with a rude supervisor: They ponder their negative treatment, which prompts them to disobey, a response that likely diminishes the chances that supervisors might change their behaviors. This detrimental process is particularly salient when employee–supervisor interactions are marked by unpleasant task-related fights.

This study unpacks an unexplored link between supervisor incivility and supervisor-directed insubordination by explicating the pertinent roles of two critical factors (rumination and task conflict) in this link.

Vision, audition, olfactory, tactile and taste are five important senses that human uses to interact with the real world. As facing more and more complex environments, a sensing system is essential for intelligent robots with various types of sensors. To mimic human-like abilities, sensors similar to human perception capabilities are indispensable. However, most research only concentrated on analyzing literature on single-modal sensors and their robotics application.

This study presents a systematic review of five bioinspired senses, especially considering a brief introduction of multimodal sensing applications and predicting current trends and future directions of this field, which may have continuous enlightenments.

This review shows that bioinspired sensors can enable robots to better understand the environment, and multiple sensor combinations can support the robot’s ability to behave intelligently.

The review starts with a brief survey of the biological sensing mechanisms of the five senses, which are followed by their bioinspired electronic counterparts. Their applications in the robots are then reviewed as another emphasis, covering the main application scopes of localization and navigation, objection identification, dexterous manipulation, compliant interaction and so on. Finally, the trends, difficulties and challenges of this research were discussed to help guide future research on intelligent robot sensors.

The relationship between perceived overqualification and knowledge sharing has always been a hot topic, but scholars have come to different conclusions on this issue. The purpose of this study is to integrate conflicting conclusions by considering the moderating role of rewards for knowledge sharing and the mediating role of intrinsic motivation in the relationship between perceived overqualification and knowledge sharing based on self-determination theory.

The authors collected three-wave survey data from 246 research and development employees in four companies in China.

The results showed that when rewards for knowledge sharing was higher, employees with perceived overqualification would have higher intrinsic motivation, which could promote their knowledge-sharing behavior. However, when rewards for knowledge sharing was lower, employees with perceived overqualification would have lower intrinsic motivation, thus inhibiting their knowledge-sharing behavior. This result supported the informational function rather than the controlling function of rewards for knowledge sharing.

By considering the important boundary condition of rewards for knowledge sharing, this study reconciles the contradictory conclusions on the relationship between perceived overqualification and knowledge-sharing behavior. At the same time, the authors tell organizations that they can increase the knowledge-sharing behavior of overqualified employees through rewards for knowledge sharing.

The performance of corporations in sustainable development is not only a concern of investors, but has also captured ever-increasing attention from consumers. However, the evidence on how these good practices would ultimately benefit brands economically remains insufficient. This study tests the causal effect between corporate Environmental, Social, and Governance (ESG) performance, media coverage, and brand value to reveal the underlying mechanisms of how consumers would react to high ESG performance.

This study uses panel data regression analysis with a sample of Chinese A-share non-financial listed companies from 2010 to 2021. ESG performance, brand value, and media coverage are assessed with Huazheng ESG Rating, the rankings from the China’s 500 Most Valuable Brands' list published by the World Brand Lab, and media index compiled by the Chinese Research Data Services Platform (CNRDS) respectively.

This research confirmed that ESG performance positively impacted brand value in terms of profitability, and that media coverage played a role as a megaphone in this relationship. Large-scale corporates, compared to small ones, benefited more from good ESG ratings due to increased media coverage.

The findings provide evidence of the megaphone effect of media coverage on the relationship between firms’ ESG engagements and brand value in the product market, which has extended the knowledge of media’s monitoring role in the financial market. And this megaphone effect is strengthened by firm size in which larger firms have spotlight effect in draw public attention due to higher expectations in terms of social responsibility.

This study aimed to examine the impact of COVID-19 concerns on employees’ well-being, considering workplace stress, aggression, and emotional outcomes, such as emotional engagement, emotional exhaustion, and negative emotional reactions. This study also considers the moderating role of technostress between workplace stress and aggression, which has been overlooked in previous studies.

Data were collected from frontline hotel employees in Turkey. Online data were collected through Amazon Mechanical Turk services. A total of 250 questionnaires were distributed. Nevertheless, only 204 questionnaires with valid responses were usable for analysis through partial least square-structural equation modeling (PLS-SEM).

The analytical findings showed that COVID-19 concerns (financial, social gaze, and technological) cause workplace stress, resulting in aggression. Aggression subsequently affects the employees’ emotional outcomes, impacting their emotional well-being. Furthermore, the results showed that technostress insignificantly moderates workplace stress and aggression.

This study provides valuable practical implications to the hotels’ top management, practitioners, and policymakers to provide preventive measures to employees, such as wearing masks and maintaining distance. Hotel practitioners should limit employees’ direct contact with customers and reduce factors that result in overall financial losses and create financial stress for employees.

The current study examined the relationships between the study’s variables in Turkey’s hotel industry context by employing the conservation of resources (COR) theory. The study investigated stress and aggression phenomena, their impact on employees’ emotional responses, and ultimately their influence on the employees’ well-being.
