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.

When a vehicle passes through a long highway tunnel, the smoke it discharges accumulates in the tunnel. High smoke concentration has an important influence on the driver’s health and driving safety. The use of numerous jet fans to diffuse the smoke causes excessive energy consumption, so it is of significant practical value to design suitable tunnel ventilation.

The study is based on the continuum hypothesis, incompressible hypothesis, steady flow hypothesis and similar hypothesis of gas in a long highway tunnel. These hypotheses calculate the gas emissions and wind demand in a long highway tunnel given the deployment of the jet fan program.

This program selects each of the two 1120-type jet machine group and sets up 13 groups; each group has an interval of 184.5 m in the end. The analysis of air test results when the tunnel is in operation shows that CO and smoke concentrations meet the design requirements, which can provide reference for a similar engineering design later.

At present, a highway tunnel is recognized at home and abroad by means of clearance of longitudinal ventilation, which is 2,000 m. In view of this, this paper is based on the theory of longitudinal jet ventilation of a highway tunnel, whose length is more than 2,000 m, to calculate the ventilation and apply it to a tunnel’s ventilation design.

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.

Firms aiming to enhance firm performance require specific investment and qualification of capability. However, the relationship between these factors and firm performance is influenced by boundary conditions. This study focuses on the role of shared values as a governance mechanism in moderating the relationship between specific investment, qualification of capability, and firm performance.

Drawing on transaction cost analysis, the authors develop a theoretical model to explore how shared values moderate the relationship between specific investment, qualification of capability, and firm performance. The authors collected data from 156 firms in Cote d’Ivoire, resulting in a sample of 216 observations. The authors employed hierarchical regression analysis and the “pick-a-point approach” to examine how specific investment and qualification of capability impact firm performance at different levels of shared values.

The results indicate that specific investment and qualification of capability have a partially positive impact on firm performance. Interestingly, shared values are an important moderating variable, acting as a boundary condition that affects the relationship between specific investment, qualification of capability, and firm performance. Specifically, specific investment leads to excellent firm performance only when shared values are not sufficiently high, whereas qualification of capability leads to superior firm performance only when shared values are sufficiently high.

This study has three research implications. First, this study enriches TCA literature by identifying shared values as a boundary condition and examining the moderating role of shared values. Second, the study findings discover new insights into how specific investment and qualification of capability enhance or inhabit organizational performance at different levels of shared values. Third, this study extends the existing research and reveals the specific conditions for positive or negative relationships between specific investment and organizational performance and qualification of capability and organizational performance.

First, compared to specific investment, qualification of capability has greater effect on organizational performance. Second, when considering whether to increase specific investment or/and improve qualification of capability, executives are encouraged to first evaluate their firm's level of shared values and then make appropriate strategic decision accordingly. Third, six tactics are recommended for enhancing shared values.

This study enriches the literature on transaction cost analysis and contributes to understanding the moderating role of shared values. The findings shed light on the specific investment, qualification of capability, and firm performance relationships. Additionally, this research highlights the importance of considering shared values as a boundary condition in examining these relationships.

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.

Organizational citizenship behaviors for the environment (OCBEs) represent a crucial element of environmental sustainability for a wide range of organizations. However, the leadership mechanisms underlying OCBEs are as yet unexplored, particularly regarding the delivering megaprojects. The paper aims to investigate how transformational leadership (TFL) and transactional leadership (TSL) styles shape the environmental commitment (EC) of subordinates, motivating OCBEs in megaprojects.

Partial least squares modeling and hierarchical regression were performed on data obtained from 140 experts who have been involved in megaprojects.

Both TFL and TSL styles are effective in motivating OCBEs, although the EC of subordinates partially mediates these relationships. The power distance (PD) orientation significantly moderates the relationship between TFL and OCBEs, with the relationship being more positive when the PD of subordinates is lower. Unexpectedly, a collectivist orientation (CO) was found to elevate the effect of TSL but weaken the effect of TFL.

The mixed and contradictory findings regarding TFL and TSL styles are reconciled in the current study by integrating the contextual factors of PD and CO. The findings of the study shed new light on “playing the cards right” when using the leadership practices, i.e. how leadership can be better leveraged to cultivate subordinates' OCBEs. They also provide targeted guidance for shaping contextual factors to increase the environmental sustainability of megaprojects.

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 purpose of this paper is to cut down energy consumption and eliminate production waste on mixed-model assembly lines. Therefore, a supermarket integrated dynamic cyclic kitting system with the application of electric vehicles (EVs) is introduced. The system resorts to just-in-time (JIT) and segmented sub-line assignment strategies, with the objectives of minimizing line-side inventory and energy consumption.

Hybrid opposition-based learning and variable neighborhood search (HOVMQPSO), a multi-objective meta-heuristics algorithm based on quantum particle swarm optimization is proposed, which hybridizes opposition-based learning methodology as well as a variable neighborhood search mechanism. Such algorithm extends the search space and is capable of obtaining more high-quality solutions.

Computational experiments demonstrated the outstanding performance of HOVQMPSO in solving the proposed part-feeding problem over the two benchmark algorithms non-dominated sorting genetic algorithm-II and quantum-behaved multi-objective particle swarm optimization. Additionally, using modified real-life assembly data, case studies are carried out, which imply HOVQMPSO of having good stability and great competitiveness in scheduling problems.

The feeding problem is based on static settings in a stable manufacturing system with determined material requirements, without considering the occurrence of uncertain incidents. Current study contributes to assembly line feeding with EV assignment and could be modified to allow cooperation between EVs.

The dynamic cyclic kitting problem with sub-line assignment applying EVs and supermarkets is solved by an innovative HOVMQPSO, providing both novel part-feeding strategy and effective intelligent algorithm for industrial engineering.

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.
