Abstract

Purpose

The purpose of this paper is to present a crack initiation mechanism of the external hydrogen effect on type 304 stainless steel, as well as on fatigue crack propagation in the presence of hydrogen gas.

Design/methodology/approach

The effects of external hydrogen on hydrogen-assisted crack initiation in type 304 stainless steel were discussed by performing fatigue crack growth rate and fatigue life tests in 5 MPa argon and hydrogen.

Findings

Hydrogen can reduce the incubation period of fatigue crack initiation of smooth fatigue specimens and greatly promote the fatigue crack growth rate during the subsequent fatigue cycle. During the fatigue cycle, hydrogen invades into matrix through the intrusion and extrusion and segregates at the boundaries of α′ martensite and austenite. As the fatigue cycle increased, hydrogen-induced cracks would initiate along the slip bands. The crack initiation progress would greatly accelerate in the presence of hydrogen.

Originality/value

To the best of the authors’ knowledge, this paper is an original work carried out by the authors on the hydrogen environment embrittlement of type 304 stainless steel. The effects of external hydrogen and argon were compared to provide understanding on the hydrogen-assisted crack initiation behaviors during cycle loading.

Abstract

Purpose

This study examined a curvilinear and moderated relationship between transformational leadership and employee creative performance in a real-world setting by drawing from the too-much-of-a-good-thing effect and the substitutes for leadership perspectives.

Design/methodology/approach

We used multisource data collected from 232 employees and their immediate supervisors to test all hypotheses.

Findings

We found empirical support for an inverted U-shaped relationship between transformational leadership and employee creative performance. Moreover, job factor (i.e. job formalization) and individual differences (i.e. power distance) moderated the curvilinear relationship, such that the curvilinear relationship was more pronounced with lower job formalization or higher power distance of employees.

Originality/value

Our findings shed light on the inconsistent reports of transformational leadership's effects on employee creativity in previous studies. We extended substitutes for leadership perspective by providing a more systematic view for future research on how leadership and its substitutes jointly influence employee outcomes.

The purpose of this paper is to examine how analyst recommendation change is associated with a firm’s magnitude of strategic change.

Abstract

Purpose

The purpose of this paper is to examine how analyst recommendation change is associated with a firm’s magnitude of strategic change.

Design/methodology/approach

This study argues that unfavorable analyst recommendation change serves as a powerful external assessment that current strategies are inappropriate and that changes are needed. This study also incorporates the moderating roles of CEO power and board’s informal hierarchy in the relationship between analyst recommendation change and firm’s magnitude of strategic change. Results from a sample of 824 observations generally support our predictions.

Findings

The findings of this study show that the greater the analysts downgrade for the company’s stock, the larger the magnitude of strategic change will be made. This study also considers the moderating roles of CEO power and the clarity of board’s informal hierarchy. In particular, the higher the CEO power, the weaker the relationship between analyst recommendation change and the magnitude of strategic change will be. The higher the clarity of board’s informal hierarchy, the more positive the relationship between analyst recommendation change and the magnitude of strategic change will be.

Originality/value

It extends research on the external predictors of strategic change by incorporating the role of unfavorable analyst recommendation change. In addition, it contributes to institutional theory by showing how external legitimacy pressure and internal corporate governance tool complement each other.

Abstract

Purpose

As information technology advances, the prevalence of AI chatbot products is on the rise. Despite optimistic market projections, consumer skepticism towards these agents persists. This paper aims to expand the scope of the technology acceptance model by integrating the aspect of appearance. It examines the influence of different attributes of AI chatbot, such as usefulness, ease of use and appearance, individually and in combination, on consumers' intentions to share and purchase.

Design/methodology/approach

Using an exploratory study of Web Texts, a 2 (usefulness: high vs low) × 2 (ease of use: high vs low) mixed design and a 2 (usefulness: high vs low) × 2 (ease of use: high vs low) × 2 (anthropomorphism appearance: humanoid vs cartoon) for between-subjects designs and the price level (high vs low) for within-subjects designs. The hypotheses were tested by Octoparse and SPSS 22.0.

Findings

The research highlights the significant role of usefulness, ease of use and anthropomorphic appearance in shaping consumer attitudes towards AI chatbots, thus influencing their intentions to share information and make purchases. Grouped regression analysis reveals that lower prices exert a more pronounced positive influence on consumers' inclinations to both share and purchase, compared to higher prices. Moreover, novelty-seeking behavior moderates the effect of perceived usefulness or ease of use on attitude. Specifically, heightened novelty-seeking tendencies mitigate the impact of low perceived usefulness or ease of use, leading to sustained positive attitudes towards AI chatbots among consumers.

Originality/value

This study innovatively incorporates product appearance into the Technology Acceptance Model (TAM), considering both the functional attributes and appearance of AI chatbot and their impact on consumers. It offers valuable insights for marketing strategies, extends the scope of TAM application and holds significant practical implications for enhancing enterprise product planning.

Abstract

Purpose

As megaprojects bear extensive and profound social responsibilities throughout the project life cycle, formulating effective measures for improving construction enterprise social responsibility is key to project success. Given the current research is relatively lack of these measures, this study aims to formulate a meta-network framework to improve the megaproject social responsibility behaviour (MSRB) for construction enterprises.

Design/methodology/approach

First, this study implements literature review, expert interview and field investigation to identify the construction enterprise MSRB and its influencing factors. Second, this study evaluates the MSRB implementation level of the selected construction enterprises and proposes the above mentioned meta-network framework. Next, this meta-network is configured to reflect the impact of MSRB strategic adjustment. Last but not least, a real-world case study is carried out to validate this framework.

Findings

The best MSRB performance is always witnessed from the contractor group, followed by the project client group and the site supervisor group. The outcomes of implementing certain managerial strategies indicate that (1) social responsibility cognition is a critical factor for all the groups; (2) communication mechanism and normative pressure are the critical factors for clients; (3) coercive pressure is a critical factor for supervisors and (4) cultural cognitive pressure is a critical factor for clients and contractors.

Originality/value

The use of the framework in proactive assessment and management of MSRB can lead to effective strategies for construction enterprises to increase the efficiency and quality of projects.

This paper intends to address the decision-making and coordination of green supply chain (GSC) considering risk-averse manufacturers under mixed carbon policy.

Abstract

Purpose

This paper intends to address the decision-making and coordination of green supply chain (GSC) considering risk-averse manufacturers under mixed carbon policy.

Design/methodology/approach

This paper focuses on a GSC consisting of a manufacturer and a retailer, in which the manufacturer is risk-averse (R-A). This paper employs Stackelberg game theory and mean variance analysis to assess the pricing decision-making process under various scenarios. Furthermore, cost-sharing contracts are introduced to coordinate the GSC.

Findings

The research results suggest that the green level of the product and the profit of the GSC under a centralized scenario are higher than those under a decentralized scenario, while the retail price is lower. Under the decentralized scenario, the green level of product, wholesale price and manufacturer’s profit in the R-A scenario are lower than the values in the risk-neutrality scenario, while retailer's profit is higher. In addition, when a cost-sharing contract is utilized for coordination in the GSC, it can lead to Pareto improvement, regardless of whether the manufacturer makes risk-neutrality or R-A decisions.

Originality/value

This research provides a deeper understanding of GSC decision-making and coordination strategy under mixed carbon policy with consideration of R-A from a theoretical perspective and provides decision support for enterprises to choose strategies in practice.

Abstract

Purpose

Drawing upon person–supervisor fit theory, a model is developed to illustrate how leader–member trait mindfulness (in)congruence may impact leader–member exchange (LMX) and how such trait mindfulness (in)congruence can indirectly influence taking charge.

Design/methodology/approach

Polynomial regression and response surface methodology are used to analyze 237 valid matched leader–member dyads.

Findings

LMX increases as leaders' and members' trait mindfulness become more aligned; LMX is higher when leader–member dyads are congruent at high levels (vs low levels). In the case of incongruence, LMX is higher when the member's trait mindfulness exceeds that of the leader. Furthermore, the relationship between leader–member trait mindfulness (in)congruence and taking charge is mediated by LMX.

Practical implications

The joint and interactive role of high trait mindfulness in leader–member dyads can help them to generate high-quality interpersonal exchange, as well as to cope with challenges posed by present and future changes.

Originality/value

The linear, nonlinear, simultaneous and interactive effects of dyadic trait mindfulness expand previous research, clarifying that the evaluation of leader–member congruence and incongruence at various degrees, and for various patterns of trait mindfulness, is more informative than examining the direct effect alone.

Abstract

Purpose

This study investigates business model innovation in small- and medium-sized manufacturing enterprises (SMEs) and its impact on firm growth.

Design/methodology/approach

The study was based on analyzing data collected through a questionnaire survey. Structural equation modeling was applied to test the hypotheses.

Findings

Business model innovation has a positive effect on SME growth in the manufacturing sectors. Moreover, growth is also achieved through the indirect effect of business model innovation on customer trust and commitment.

Practical implications

Managers will benefit from understanding how business model innovation can help their companies to overcome resource constraints and achieve sustained growth. When manufacturing SMEs engage in modular or structural changes to their business model, they may find it worthwhile to focus on maintaining a relationship of trust and commitment with their customers.

Originality/value

This study highlights business model innovation as a unique and important, yet underexplored, factor in manufacturing SME growth. The findings also untangle the complex processes of customer relationship management by which business model innovation improves manufacturing competitive advantage for SMEs.

Abstract

Purpose

The alienation of megaproject environmental responsibility (MER) behavior is destructive, but its mechanism has not been clearly depicted. Based on fraud triangle theory and the fuzzy set qualitative comparative analysis (fsQCA) method, this study explored the combined effect of antecedent factors on alienation of MER behavior.

Design/methodology/approach

Based on the fraud triangle theory and literature review, eight influencing factors associated with the alienation of MER behavior were first identified. Subsequently, the fuzzy-set qualitative comparative analysis was used in this study to reveal configurations influencing alienation of MER behavior.

Findings

The study found nine configurations of MER behavioral alienation antecedent factors, integrated into three types of driving modes, i.e. “economic pressure + learning effect,” “institutional defect + moral rejection,” and “information asymmetry + economic pressure + expectation pressure.”

Originality/value

By analyzing the configuration effects of various induced conditions, this study puts forward a comprehensive analysis framework to solve the alienation of MER behavior in the megaprojects and a practical strategy to control alienation of MER behavior.
