Abstract

Purpose

This paper aims to provide SIF calculation method for engineering application.

Design/methodology/approach

In this paper, the stress intensity factors (SIFs) calculation method is applied to the anisotropic Ni-based single crystal film cooling holes (FCHs) structure.

Findings

Based on contour integral, the anisotropic SIFs analysis finite element method (FEM) in Ni-based single crystal is proposed. The applicability and mesh independence of the method is assessed by comparing the calculated SIFs using mode of plate with an edge crack. Anisotropic SIFs can be calculated with excellent accuracy using the finite element contour integral approach. Then, the effect of crystal orientation and FCHs interference on the anisotropic SIFs is clarified. The SIFs of FCH edge crack in the [011] orientated Ni-based single crystal increases faster than the other two orientations. And the SIF of horizontal interference FCHs edge crack is also larger than that of the inclined interference one.

Originality/value

The SIFs of the FCH edge crack in the turbine air-cooled blade are innovatively computed using the sub-model method. Both the Mode I and II SIFs of FCHs edge crack in blade increase with crack growing.

Abstract

Purpose

Principals’ leadership has become a subversive activity that is carried out strategically to challenge and disrupt the status quo and resist policies and practices that are counterproductive to their work. The purpose of this paper is to reveal subversive tactics principals use in pursuit of justice and equity in schools and identify challenges and risks associated with their subversive leadership practices. Power tactics were used as a conceptual framework to guide the analysis of subversive activities by school principals.

Design/methodology/approach

This qualitative study focuses on 18 elementary and secondary school principals from six district school boards in the Metro Vancouver area who participated in the semi-structured interviews on their practices that epitomize different tactics in response to increasing demand and accountability.

Findings

The power tactics identified in this study illuminate many of the dilemmas principals face in their work and demonstrate the various ways principals exercise their political acumen to “act strategically to determine which tactics to use, when, and with whom.” In exercising ethics of subversion and critique, participants are more likely to use soft, rational, and bi/multilateral rather than hard, non-rational, and unilateral power tactics. Such tendency reveals their concern about causing relational harm and shows their strategic avoidance of direct confrontation.

Research limitations/implications

Considering the limitations on the sample size and the research context, more research is needed to examine to what extent subversive practices are exercised and how they play out in different contexts.

Originality/value

The study shows that leadership involves upholding morals and values, even if this means having to use subversive practices to ensure inclusive, equitable, and just outcomes.

Abstract

Purpose

In the hybrid knowledge-sharing platform where paid and nonpaid (“free”) knowledge activities coexist, users’ free knowledge contribution may be influenced by financial factors. From the perspective of opportunity cost, this study investigates the direct effect of how the amount of monetary income from users’ contribution to paid knowledge activities influences their free knowledge contribution behavior in the future. Further, this study aims to verify the interaction effect of financial and nonfinancial factors (i.e. the experience of free knowledge contribution and social recognition) on free knowledge contribution.

Design/methodology/approach

Objective data was collected from a hybrid knowledge-sharing platform in China and then analyzed by using zero-inflated negative binomial regression model.

Findings

Results show that the amount of monetary income that knowledge suppliers gain from paid knowledge contribution negatively influences their free knowledge contribution. Experience of free knowledge contribution strengthens the negatively main effect, while social recognition has the weakening moderating role.

Originality/value

Although some studies have explored and verified the positive spillover effect of financial incentives on free knowledge contribution, the quantity dimension is ignored. This study examines the hindering influence of the quantity of monetary income from the perspective of opportunity cost. By taking the characteristic of knowledge suppliers and platforms as moderators, this study deepens the understanding of the influence of monetary income on free knowledge contribution in the hybrid knowledge-sharing platform.

Abstract

The People’s Republic of China, as a progressively developing economy, is subject to dynamic structural changes, which are potentially de‐stabilizing in nature. Since the end of the 1970s China had abandoned Mao Zedong’s socioeconomic theories and policies and instituted profound socioeconomic reforms. Her more pragmatic approach has increasingly emphasized economic freedom and individualism. The pursued “pragmatism” involves a revolutionary mixture of both a planned and a market economy with greater economic but not political freedom. Essential socioeconomic reforms were not complemented by requisite political reforms. According to Walter Eucken’s “instability thesis,” this may de‐stabilize China’s socioeconomic and political structures. The challenge which China continues to face is how to reconcile two sets of conflicting principles, economic freedom and Marxist‐Leninist‐Maoist control of politics and society, resolving Eucken’s hypothesis of potential long‐term instability. This paper addresses this challenge in terms of ethical and economic perspectives.

Abstract

Purpose

The purpose of this paper is to examine how subnational institutions within a country explain the performance consequences of open innovation (OI) in emerging market enterprises (EMEs).

Design/methodology/approach

The paper conducts a regression analysis by using a novel panel data set comprising of 438 innovative Chinese firms over the period of 2008-2011.

Findings

The authors show that although on average openness to external actors improves innovation performance this effect is pronounced for EMEs that operate in subnational regions with a higher level of intellectual property rights (IPR) enforcement and of factor market development. The findings point to the context-dependent nature of OI strategy and the complementary effect of institutional parameters in emerging markets and help to reconcile the contrasting findings regarding the effect of OI in the prior literature.

Originality/value

This paper extends the literature on OI by suggesting that the analysis of the performance consequences of OI strategy should go beyond the nexus between OI and firm performance, and instead, focus on subnational-specific institutions, such as region-specific IPR enforcement, factor market development and intermediation market development, that may facilitate or constrain the effect of OI model.

Abstract

Purpose

Research about the modern mutually beneficial nonprofit organizations (MBNPOs) has great value because of the increasingly important role that the MBNPO plays in society. The establishment and management of MBNPOs are critical for its development.

Design/methodology/approach

Integrated marketing communications (IMC) theory is applied to the research on establishment and management innovation. The establishment of MBNPOs needs four sequential steps: identifying the target group, providing services to meet the demand of stakeholders, designing appropriate communication tactics and deploying proper organizational structure to accomplish efficient communication.

Findings

Three types of approach enable traditional enterprises to transform into MBNPOs: product innovation, operational innovation and synergetic development. The application of IMC theory accomplishes management innovation of MBNPOs in three aspects: leading market-orientation specific to stakeholder-orientation, making management innovation systematic in MBNPOs and clarifying targets of management innovation in MBNPOs.

Originality/value

This is one of the first examinations of establishment path and management innovation of MBNPO based on IMC theory.

Abstract

Purpose

The geological conditions of Longyang Reservoir are complex and it is located in strong earthquake area. In order to determine its seismic characteristics, the seismic response and residual deformation of embankment dam should be studied to provide calculation basis for dam design and construction.

Design/methodology/approach

Based on the geological survey data of Longyang Reservoir, the dam filling materials are tested by dynamic deformation tests, and the equivalent linear constitutive model parameters of the filling materials are obtained. Based on Duncan-Chang E-B model, the stress state of embankment dam in Longyang Reservoir before earthquake is calculated, and the dynamic response and earthquake residual deformation of embankment dam in Longyang Reservoir under earthquake condition are calculated by using equivalent linear model and Shen Zhu-jiang’s residual deformation model.

Findings

The results show that with the increase of dynamic shear strain, the dynamic shear modulus decreases and the damping ratio increases. The scatter plot between dynamic shear modulus and dynamic shear strain, and the scatter plot between damping ratio and dynamic shear strain under different confining pressures show strips. The calculation results shows that the acceleration of embankment dam in Longyang Reservoir increases with the increase of dam height, and the acceleration distribution has obvious amplification effect. Combined with the maximum dynamic shear strain during the earthquake and the state before the earthquake, the maximum vertical residual deformation of embankment dam in Longyang Reservoir is 2.98 cm which occurs at the top of the dam, calculated by the Shen Zhu-jiang’s residual deformation model.

Originality/value

Finite element calculation model parameters of embankment dam are obtained by dynamic triaxial tests. Seismic dynamic responses and residual deformation of embankment dam are analyzed. With the increase of dam height, the acceleration distribution shows an obvious amplification effect. The vertical displacement of embankment dam is larger along the dam axis and decreases in the upstream and downstream direction. The maximum horizontal displacement of embankment dam occurs in the middle of upstream and downstream dam slopes.

Abstract

Purpose

As an essential personality charm of leaders, humor can bring a series of positive outcomes to both users and receivers. However, there is also evidence that the impact of leaders’ humor (LH) is constrained by individuals, teams and organizational factors. The aim of this research is to investigate the relationship between LH and subordinates’ service creativity. Based on social learning theory and previous literature on LH, this paper identifies role modeling as the mediator and suggests that subordinates’ sensitivity to favorable interpersonal treatment (SFIT) moderates these relationships.

Design/methodology/approach

In order to test the proposed moderated mediation model, this study employed hierarchical multiple regression and path analyses with valid data of 348 samples.

Findings

Results revealed that LH positively affects role modeling and service creativity of subordinates, while subordinates' SFIT positively moderates the relationship between LH and subordinates' service creativity via role modeling.

Practical implications

In compliance with these findings, this research suggests that enterprises should pay attention to the role of humor from middle managers and strengthen managers' role modeling through multiple measures to establish a relaxed and harmonious atmosphere in the workplace.

Originality/value

Built on the conceptual framework, this study contributes to the literature on LH and employees’ service creativity by treating role modeling as the mechanism and SFIT as the moderator. This research is one of the first few empirical studies to investigate the relationship between LH and service creativity of service personnel in the service industry.
