Drawing on the challenge–hindrance stressor framework and the “too-much-of-a-good-thing” principle, this study examined the curvilinear effects of two emic social challenge stressors (guanxi beliefs and participative decision-making (PDM)) and the moderating effect of an etic social hindrance stressor (perceived organizational politics) on Hong Kong and United States nurses’ job satisfaction.

A quantitative survey method was implemented, with the data provided by 355 Hong Kong nurses and 116 United States nurses. Structural equation modeling was used to examine the degree of measurement equivalence across Hong Kong and US nurses. The proposed model and the research questions were tested using nonlinear structural equation modeling analyses.

The results show that while guanxi beliefs only showed an inverted U-shaped relation on Hong Kong nurses’ job satisfaction, PDM had an inverted U-shaped relation with both Hong Kong and United States nurses’ job satisfaction. The authors also found that Hong Kong nurses experienced the highest job satisfaction when their guanxi beliefs and perceived organization politics were both high.

The results add to the comprehension of the nuances of the often-held assumption of linearity in organizational sciences and support the speculation of social stressors-outcomes linkages.

Managers need to recognize that while the nurturing and development of effective relationships with employees via social interaction are important, managers also need to be aware that too much guanxi and PDM may lead employees to feel overwhelmed with expectations of reciprocity and reconciliation to such an extent that they suffer adverse outcomes and become dissatisfied with their jobs.

First, the authors found that influences of guanxi beliefs and PDM are not purely linear and that previous research may have neglected the curvilinear nature of their influences on job satisfaction. Second, the authors echo researchers’ call to consider an organization’s political context to fully understand employees’ attitudes and reactions toward social interactions at work. Third, the authors examine boundary conditions of curvilinear relationships to understand the delicate dynamics.

This research proposes and examines a theoretical model grounded in anthropomorphism theory considering the curvilinear and linear relationships between service robot anthropomorphism and consumer usage intention and explores the mediating effect of perceived risk.

To examine the developed model, two complementary studies are designed. In Study 1, multi-time data of 511 participants show that service robot anthropomorphism inverts U-shaped (curvilinear) relationship on consumer usage intention and perceived risk mediates this curvilinear relationship. In Study 2, multi-source data of 460 volunteers are used to confirm the findings of Study 1 and examine that consumer empathy moderates the complex nonlinear effect of service robot anthropomorphism on perceived risk, and the indirect curvilinear effect of service robot anthropomorphism on consumer usage intention through perceived risk.

This research provides preliminary and yet important findings on how service robot anthropomorphism most likely is positively associated with consumer usage intention, i.e. the positively influence mechanism of service robot anthropomorphism on consumer usage intention.

This study proposes that the relationship between the employee's moral identity and unethical behavior might sometimes differ from linearly negative, given certain contextual variations, such as unethical pro-organizational behavior (UPB). The pro-organizational motivation of UPB may appeal to individuals' morality to perform unethical behavior for their organization. Herein, using the social identity perspective, the present study hypothesizes a curvilinear relationship between moral identity and UPB with the moderation of organizational identification.

Data collected in two field studies, from 316 and 185 executives in Study 1 and 2, was analyzed using hierarchical regression analysis.

The results affirmed an inverted U-shaped relationship between moral identity and UPB. Further, organizational identification moderated the relationship such that an increase in organizational identification augmented the UPB tendency for low moral identity individuals while inhibiting the UPB tendency for high moral identity individuals.

The current study uniquely demonstrates how moral identity might promote unethical behavior in pro-organizational contexts. Further, this research shows how high moral identity might mitigate the negative outcomes of high organizational identification.

Past research has generally purported and tested for a positive linear relationship between psychological capital and organizational outcomes such as firm performance. Yet, recent conceptual work has started to recognize that for certain outcomes, too much psychological capital can be as detrimental as too little. In this study, the author hypothesizes that during a major crisis, organizational psychological capital (OPsyCap) may in fact exhibit an inverted U-shaped relationship with performance.

T leverages the revelatory power of a recent major crisis (the COVID-19 pandemic) to gather a pre-crisis and post-crisis matching sample of 952 earnings conference calls held by 476 S&P 500 firms with corresponding market performance data and use computer-assisted text analysis (CATA) methodology to assess OPsyCap from call transcripts.

T finds that OPsyCap has a statistically significant inverted U-shaped relationship with market performance after the crisis, but not prior—thereby suggesting that moderate OPsyCap is more beneficial to market performance than either insufficient or excessive OPsyCap in times of crisis.

Top managers should not display overly excessive psychological capital after a major crisis, as shareholders may interpret such cues as unwarranted optimism, overconfidence and an inability to accept the new reality brought about by the crisis.

This study's findings contribute to extant literature by being the first to empirically highlight a curvilinear relationship between psychological capital and an important outcome variable—market performance. Furthermore, this study's lack of results prior to a major crisis, but not after, may suggest a new boundary condition.

Servitization of products is becoming increasingly prevalent among manufacturing enterprises. Existing research has primarily focused on exploring whether the direct impact of servitization on manufacturer performance follows a linear or a curvilinear relationship. However, the understanding of the underlying mechanisms between servitization and manufacturer financial performance remains limited. This paper aims to examine the non-linear relationship between servitization and manufacturer performance as well as the mediating process and boundary condition associated with this relationship.

Drawing on resource-advantage theory, this paper proposes a theoretical model of the U-shaped relationship between servitization and the financial performance of equipment manufacturers. Panel data of 248 listed equipment manufacturers in China during the period of 2010–2020 are used to test each hypothesis through the ordinary least square method.

The empirical results indicate that servitization follows a U-shaped relationship with service business focus and the financial performance of equipment manufacturers. Service business focus mediates this U-shaped relationship between servitization and financial performance, and digital technology application moderates this relationship.

This paper pioneers the unraveling of the potential mechanism that can explain the curvilinear relationship between servitization of manufacturers and financial performance. This mechanism is the focus of the service business, which is theoretically delineated and empirically tested. Furthermore, digital technology application enables manufacturers to achieve service business focus more effectively in the process of servitization. Thus, this study addresses the call for research on digital servitization.

Prior innovation orientation research has mostly focused on performance consequences, with some recent work examining its relationship with innovative practices such as open innovation. Yet, despite this growing body of open innovation research, there are still gaps and limitations. Notably, most prior studies have been conducted in Europe, limiting their generalizability to the rest of the world, and are replicative, exploring performance and competitive outcomes. There is very limited work examining the potential limitations of open innovation. This study extends innovation orientation research and examines the limitations of open innovation in North America.

This study explores the relationships between innovation orientation and performance, open innovation and performance and innovation orientation and open innovation among 386 North American companies.

This study is novel as it examines the relationships between innovation orientation and performance, open innovation and performance and innovation orientation and open innovation among North American companies. The research uncovers a linear relationship between innovation orientation and performance, a correlation between innovation orientation and open innovation and a counterintuitive curvilinear relationship between open innovation and performance. The curvilinear relationship, shaped as an inverted u-shape, suggests there are limitations to the strategy's effectiveness, actionable insight to companies, consultants and scholars alike. In the discussion section, findings are further unpacked with regard to their implications for the scholarly literature. The paper concludes with managerial considerations for creating an innovation orientation and the most effective level of open innovation for maximum competitive and performance implications.

Beyond the innovation orientation and open innovation research contributions, this study offers managerial insight for executives seeking to enhance competitiveness and drive firm performance.

This paper aims to assess the feasibility of additively manufactured wind tunnel models. The additively manufactured model was used to validate a computational framework allowing the evaluation of the performance of five wing models.

An optimized fighter wing was additively manufactured and tested in a low-speed wind tunnel to obtain the aerodynamic coefficients and deflections at different speeds and angles of attack. The flexible wing model with optimized curvilinear spars and ribs was used to validate a finite element framework that was used to study the aeroelastic performance of five wing models. As a computationally efficient optimization method, homogenization-based topology optimization was used to generate four different lattice internal structures for the wing in this study. The efficiency of the spline-based optimization used for the spar-rib model and the lattice-based optimization used for the other four wings were compared.

The aerodynamic loads and displacements obtained experimentally and computationally were in good agreement, proving that additive manufacture can be used to create complex accurate models. The study also shows the efficiency of the homogenization-based topology optimization framework in generating designs with superior stiffness.

To the best of the authors’ knowledge, this is the first time a wing model with curvilinear spars and ribs was additively manufactured as a single piece and tested in a wind tunnel. This research also demonstrates the efficiency of homogenization-based topology optimization in generating enhanced models of different complexity.

This paper examines the effect of market knowledge on market success of product innovativeness and the moderating role of absorptive capacity. We separated market knowledge into market diversity and market significance components and examined their effects on radical product innovation performance.

This paper adopted the secondary database study. Excluding cases with missing values of main variables, a total of 1,219 Taiwanese manufacturing firms from the Third Taiwan Technology Innovation Survey (TTIS3) database were used to test the hypotheses. A moderated hierarchical regression approach was utilized to analyze the data.

The results revealed that the relationship between market diversity and radical product innovation performance is a predominantly positive concave downward curve. In contrast, the relationship between market significance and radical product innovation performance is a predominantly negative concave downward curve. Furthermore, the results also indicated that absorptive capacity has different moderating effects on the relationships between market diversity/significance and radical product innovation performance. Absorptive capacity enhances the negative effect of market significance but suppresses the positive effect of market diversity on radical product innovation performance.

This paper is the first research which contributes to examining the relationship between market knowledge and radical product innovation sale performance.

The modern construction industry is highly competitive and cost driven, with tangible adversarial relationships between projects' contractual parties at individual and organisational levels; there are conflict of interest as people to survive. Accordingly, team leaders on construction megaprojects (CMPs) in multinational engineering organisations strive to survive in such competitive markets. The research’s aim is to investigate relationships between team leaders' tenure and management styles towards professional subordinates on CMPs and elaborate how corporate governance can optimally address this conflict of interest and adversarial relationships.

The research methodology adopted processes of inducting theory using case studies. A qualitative approach was adopted as a primary data collection and analysis source. It involved case studies through primary data collection in semi-structured face-to-face interviews with 38 professional subordinates (interviewees) to discuss impacts of team leaders' tenure on their management style (a five-team leader, case studies). The research methodology is based on building theories from case study grounded theory research methodologies.

The research introduced the notion that team leader survival syndrome is pronounced and evidenced by adversarial reactions towards new or experienced professional subordinates where team leaders perceive professional subordinates, especially at senior technical levels, as potential risks that jeopardise their positions and employment survival possibilities. The syndrome is proven based on real-life case studies; it is constant, tangible and serious disorder of attitudes and behaviours. Longer tenure stimulates and accelerates these phenomena and syndrome, with 58% of team leaders exhibiting such syndromes. Optimum employee tenure is between 7 and 10 years. Corporate governance provides good resolution practices.

The research implications are useful to construction industry and academia. However, the analysis is limited to the case studies considered in Canada and Qatar. Due to small sample size for both case studies and respondents to the questionnaire survey, it is recommended for future exploration to expand the scope of research to larger sample size and various demographic and geographical locations.

Corporates should acknowledge the presence of team leader survival syndromes. They should thoroughly investigate sociopolitical relationships behind it and seek to understand consequences on professional subordinates. Corporates should also adopt a 360-degree feedback system; they should limit trust given to team leaders in this regard to responsible trust, to eliminate manipulation. Team leaders are perceived as being not always truthful and misrepresent capabilities and performance of their professional subordinates to senior managers. Corporate governance holistic multidimensional perspectives are required to provide resolutions of team leader survival syndromes.

The research has discovered a phenomenon that team leaders on CMPs in architecture, engineering and construction (AEC) organisations, prompted by virtue of long tenure in corporates or by power of their managerial level in organisations, perceive their professional subordinates, especially senior technical employees, as potential risks. It is thought promoting them would put their own positions and security of tenure at risk. Hence, team leaders act adversarially, to enhance their own survival prospects. This research introduced the novel team leader survival syndrome and introduced analyses, practical implications and recommendations.

Current open innovation (OI) and external knowledge search (EKS) research primarily shows a positive linear relationship between EKS and innovation at an individual level. However, organizational scholarship argues that excessive EKS may harm innovation. This study combines the knowledge-based view (KBV) and attention-based view (ABV) to articulate a nonlinear theory of EKS and innovation at the individual level.

The authors constructed a multi-sourced dataset covering 59,798 USA pharmaceutical patents spanning from 1975 to 2014 and employed negative binomial fixed-effect models to examine theoretical hypotheses.

We find a significant concave curvilinear relationship between EKS and innovation quantity as well as innovation quality at an individual level. An individual’s knowledge breadth and depth moderate the relationship between EKS and innovation, such that the threshold at which EKS has diminishing returns for individual innovation is higher for inventors with a broad range of knowledge and those with deeper expertise in the domain where they are innovating.

Managers should guide inventors toward a moderate investment of time and effort in EKS and should caution against over searching. Besides, managers should recognize that an inventor’s capacity for EKS is determined in part by their breadth of knowledge across various domains as well as the depth of knowledge they have in the knowledge domain where they are innovating.

We provide both parties with a clearer understanding of when EKS can begin to deteriorate an individual’s innovation performance why that deterioration occurs, and we also highlight two individual-level knowledge characteristics to take into consideration when deciding when to cease the EKS process.

This study provides a novel holistic understanding of OI and knowledge management for policymakers and organizations to nourish innovation dynamism and make the best of knowledge stocks in the community, which in turn will create endless power for sustainable social change and inclusive development.

This study contributes to OI theory by highlighting the non-linear nature of the relationship between EKS and innovation on an individual level. This represents a fundamental shift in theory on EKS and individual innovation by suggesting a major rethinking of how the two concepts relate, revealing the dark side of EKS in knowledge management if inventors engage in excessive EKS. Likewise, our study’s incorporation of the ABV informs KBV scholarship by highlighting the role of the limited attentional capacity of individuals in firm knowledge management.
