The authors investigated a psychological process that links characteristics of events related to the coronavirus disease (2019) COVID-19 pandemic (i.e. perceived novelty, disruptiveness and criticality) to compassion fatigue [(CF), a form of caregiver burnout] and subsequent post-traumatic stress disorder (PTSD) in nurses.

Administering two online surveys (October and November 2020) resulted in matched data from 175 nurses responsible for patient care during the COVID-19 pandemic.

Perceived disruptiveness and criticality of COVID-19 events were positively associated with nurses' CF, which also mediated those characteristics' effects on PTSD instigated by COVID-19. Contrary to the authors' hypothesis, the perceived novelty of COVID-19 events was not significantly associated with CF nor was the indirect effect of perceived novelty on PTSD mediated by CF.

The authors extend event system theory by investigating the psychological processes linking event features and resultant outcomes while providing practical implications on preparations for future unexpected and potentially life-altering events.

Organizations use enterprise social media (ESM) platforms to operate, function, and develop. However, the effectiveness of the use of ESM is inconclusive. This study aims to explore the mechanism and boundary conditions of the relationship between employee ESM use and job performance.

This study uses a 2-wave survey design, with a final sample of 481 employees from a large automobile company.

The results indicate that ESM use is beneficial and detrimental to job performance. On the one hand, ESM use is positively related to work overload, decreasing job performance. On the other hand, ESM use is positively associated with informational support, increasing job performance. A mediation test revealed that both work overload and informational support mediate the relationship between ESM use and job performance. Furthermore, job autonomy weakens the positive relationship between ESM use and work overload, but strengthens the positive relationship between ESM use and informational support.

This study provides a more balanced view of how ESM use influences job performance by demonstrating the opposing mediating roles of work overload and informational support. Further, this study fills a research gap by considering job characteristics when examining the boundary conditions of ESM use. Third, this study validates the generalization of the job demands-resources model in social media research.

The authors explain the conditions under which positive personality traits and work environment factors either interact synergistically or yield diminishing-gains when creative individuals are in a supportive working environment.

Data were obtained using a time-lagged design. The final sample includes 350 researchers from 64 scientific research teams.

The results indicate that the need for cognition is positively associated with individual creativity. Furthermore, this study suggests that perceived organizational support for creativity can complement an individual's need for cognition when it comes to individual creativity. This indicates a synergistic pattern. On the other hand, psychological safety can substitute for an individual's need for cognition when influencing individual creativity. Thus, a diminishing-gains pattern also exists.

The results suggest that when individuals are stuck in environments of low psychological safety, yet perceive higher levels of organizational support for creativity, their levels of creativity can be boosted.

This study is among one of the first to explore a supportive context's complementary or substitution effect on positive personality traits by demonstrating the complementary effect of perceived organizational support for creativity and the substitution effect of psychological safety. This study validates the positive effect of the need for cognition on creativity. This study also enriches the psychological safety literature by showing that psychological safety is not always necessary for individuals with a high need for cognition.

The traction behaviours of lubricating oil significantly affect the stability and lubrication regime of aviation high-speed ball bearings. Rolling elements will slide at a low traction force (TF). Therefore, traction behaviours need to be studied, and a fitting expression for traction curves to rapidly calculate the traction coefficient (TC) should be developed.

The traction behaviours of an aviation lubricating oil were studied in severe operating conditions with a self-designed two-disc testing rig. Based on the least squares method and the Levenberg–Marquardt theory, a rapid calculation expression was developed by fitting the obtained traction curves. The correction of this expression was experimentally verified by comparing the TCs under different operating conditions. This expression was also used to modify the commonly accepted quasi-dynamic model of rolling bearings.

An increase of the load led to an increase in the TC. In comparison, the temperature and entrainment speed showed inverse effects. The proposed expression exactly predicted the trend of the experimentally acquired traction curve. The calculation with the modified dynamic model showed that the action of the TF on a single rolling element varied and that the temperature increase of the outer raceway is higher than the inner raceway, which is caused by the TF and relative sliding speed between the elements and raceways.

The proposed fitting expression is able to simplify the TC calculation of synthetic aviation lubricating oil in practical engineering applications. This paper can provide an important reference for the traction behaviour of synthetic aviation lubricating oil under severe conditions and assist with its rapid calculation and practical application in engineering.

This study aims to investigate an underexplored behavioral factor, knowledge hiding, that connects employees’ perceptions of organizational politics (POP) with their diminished promotability, while also considering the moderating role of employees’ harmony motives in this process.

The research hypotheses are tested with multisource, three-round data collected among employees and their supervisors.

Employees’ beliefs about self-serving organizational decision-making increase their propensity to hide knowledge, which, in turn, diminishes their promotability. This intermediate role of knowledge hiding is more prominent when their disintegration avoidance motive is strong but less prominent when their harmony enhancement motive is strong.

A refusal to share knowledge with organizational colleagues, as a covert response to POP, can create a negative cycle for employees. They are frustrated with decision-making practices that are predicated on favoritism, but by choosing seemingly subtle ways to respond, they compromise their own promotion prospects. To avoid this escalation, employees should adopt an active instead of passive approach toward maintaining harmony in their work relationships.

This research contributes to extant research by detailing a hitherto overlooked reason that employees’ frustrations with dysfunctional politics may escalate into an enhanced probability to miss out on promotion opportunities. They respond to this situation by engaging in knowledge hiding. As an additional contribution, this study details how the likelihood of this response depends on employees’ harmony motives.

The recent rise of economic nationalism intensifies consumers' patriotic attitudes toward goods or services and thus encourages enterprises to build patriotic brand images. Nevertheless, few studies have discussed how a patriotic brand image is developed. The purpose of this study aims to fill the gap by examining whether and how a positive corporate image helps a domestic brand establish a patriotic brand image and in turn enhances consumers' purchase intentions in relation to domestic brand products.

A research model identifying the antecedents of patriotic brand image (the components of corporate image) is proposed and empirically tested using structural equations with a questionnaire investigating Taiwanese college students' attitudes toward Taiwanese smartphone brands. Three competing models are also proposed and tested to confirm the appropriateness of the research model.

In addition to the widely recognized impact of perceived quality on purchase intentions, patriotic brand image is found to be effective in enhancing local consumers' intentions to purchase domestic brand products. To shape a patriotic brand image, perceived quality, perceived corporate ability and perceived corporate integrity are the direct approaches, while perceived corporate social responsibility works through perceived corporate integrity, and perceived employer brand enhances only perceived corporate social responsibility.

Potential sampling (college students) and subject (smartphones) biases may limit the generalizability of the presented findings

While patriotic appeals have long been used in marketing communication, they are also likely to precipitate negative brand associations (e.g. nationalism), offending consumers in other countries. By contrast, the development of a positive corporate image serves as an implicit and neutral approach to building a patriotic brand image and can help domestic brands attract local consumers with less harm to foreign markets.

This study is one of notably few studies discussing patriotic brand image and its impacts on purchase intentions. This study also identifies the antecedents of patriotic brand image and how each of them affects patriotic brand image. The findings can help guide domestic brands in building a patriotic brand image.
