Abstract

Purpose

Previous studies have proposed that correctly managing stakeholders with certain attributes can benefit project management; however, robust theoretical elaborations and empirical investigations of this topic have been lacking. The purpose of this study is to empirically test the effects of two stakeholder attributes – contractor-perceived contractor salience and contractor project position – on the criticality of five typical contractor-related risks: risk of (1) injuries and accidents, (2) quality defects, (3) work delays, (4) cost overruns and (5) breaches of contract.

Design/methodology/approach

Questionnaire data were collected from 118 Chinese contractor managers. Regression models were run in Mplus 7.11 to test the hypotheses.

Findings

The data show that higher contractor-perceived contractor salience and a more supportive contractor project position were both related to lower criticality of contractor-related risks, including risk of (1) injuries and accidents, (2) quality defects, (3) work delays, (4) cost overruns and (5) breaches of contract. Contractor salience also mediated the negative relationship between a supportive contractor project position and the criticality of contractor-related risks.

Research limitations/implications

The authors’ research design is cross-sectional and thus cannot establish causation in the relationships among the studied variables. The single item measure of contractor project position was used for the first time in the present study; thus, its reliability and validity still await more empirical examinations.

Originality/value

The findings advance the understanding of the value of stakeholder management in projects by specifying that prioritizing stakeholders' claims and securing their support for the project reduce the criticality of stakeholder-related risks. By providing empirical evidence from the construction context, the findings also add to knowledge on the instrumental power of stakeholder management in enhancing project risk management performance.

Abstract

Purpose

This paper aims to present a novel dynamic reliability model that considers the interval mixed uncertainty for the air-breathing hypersonic flight vehicle (AHFV) to guarantee flight safety and structural reliability.

Design/methodology/approach

Initially, the force condition of the fuselage is analyzed based on the longitudinal elastic model of an AHFV. Subsequently, a new high-efficiency dynamic reliability model is presented to describe the failure probability evolution of the fuselage structure. For the random uncertainty problem with interval distribution parameters, the interval PHI2 method of time-dependent reliability is used to obtain the time-dependent reliability interval of the AHFV. Finally, the key variables that affect the failure probability accumulation are determined, which provide an important reference for ensuring structural reliability and improving the life span of AHFVs.

Findings

It is demonstrated that the proposed reliability model can obtain more accurate dynamic reliability results for the fuselage, and it is confirmed the key variables that affect the failure probability accumulation. The results also provide an important reference for the reliability analysis of hypersonic vehicles.

Originality/value

The novelty of this work comes from the first application of the PHI2 method (considering the interval mixed uncertainty) in the AHFV and the development of a new reliability model for the entire body of AHFVs. The proposed analysis scheme is implemented on the dynamic model of the AHFV, which provides a more accurate reference for improving the structural reliability and life span of AHFVs.

Abstract

Purpose

The purpose of this paper is to design a smart handheld device with force regulating function, which demonstrates the concept of patient-specialized tools.

Design/methodology/approach

This handheld device integrates an electrical bioimpedance (EBI) sensor for tissue measurement and a constant force regulation mechanism for ensuring stable tool–tissue contact. Particular focuses in this study are on the design of the constant force regulation mechanism whose design process is through genetic algorithm optimization and finite element simulation. In addition, the output force can be changed to the desired value by adjusting the cross-sectional area of the generated spring.

Findings

The following two specific applications based on ex vivo tissues are used for evaluating the designed device. One is in terms of safety of interaction with delicate tissue while the other is for compensating involuntary tissue motion. The results of both examples show that the handheld device is able to provide an output force with a small standard deviation.

Originality/value

In this paper, a handheld device with force regulation mechanism is designed for specific patients based on the genetic algorithm optimization and finite element simulation. The device can maintain a steady and safe interaction force during the EBI measurement on fragile tissues or moving tissues, to improve the sensing accuracy and to avoid tissue damage. Such functions of the proposed device are evaluated through a series of experiments and the device is demonstrated to be effective.

Abstract

Purpose

Frontline employees’ proactive behaviors (i.e. job crafting) are critical to satisfying customers’ idiosyncratic needs. If the supervisors practice job crafting, their subordinates are more likely to mimic such behaviors. However, there has been limited research on how leaders’ job crafting can influence subordinates’ job crafting. This study aims to examine the cross-level mechanisms (i.e. trickle-down effects) of supervisors’ job crafting on the subordinates’ attitudes and performance. Specifically, such trickle-down effects can be explained via two cross-level mechanisms of the supervisors’ job crafting on the subordinates’ work engagement and performance: social learning mechanism and job demands-resources mechanism.

Design/methodology/approach

A three-wave cross-lagged study was conducted in two-week intervals. The valid responses from 67 supervisors and their 201 subordinates were collected. The data set was analyzed using multilevel Structural Equation Modeling.

Findings

The results demonstrated that the social learning and job demands-resources mechanisms are not independent. The supervisor’s job crafting improves employment relationships, subsequently encourages subordinates’ job crafting and ultimately enhances work engagement and work performance.

Practical implications

The findings suggested that hospitality organizations should encourage job crafting among supervisors and managers. A proactive hotel manager can establish strong employment relationships, motivate subordinates to work proactively and obtain positive work outcomes.

Originality/value

The findings enrich the knowledge about the trickle-down effects of supervisors on subordinates in terms of job-crafting behaviors. In particular, this study found a new theoretical perspective that the job demands-resources and social learning mechanisms may not be independent, and the subordinates’ perception of the employment relationship plays a critical role.

Abstract

Purpose

This study investigates how social interaction-oriented content in broadcasters' live speech affects broadcast viewers' purchasing and gift-giving behaviors and how broadcaster popularity moderates social interaction-oriented content's effect on the two different behaviors in live-streaming commerce.

Design/methodology/approach

A research model was proposed and empirically tested using a panel data set collected from 537 live streams via Douyin (the Chinese version of TikTok), one of the most popular live broadcast platforms in China. A fixed-effects negative binomial regression model was used to examine the proposed research model.

Findings

This study's results show that social interaction-oriented content in broadcasters' live speech has an inverted U-shaped relationship with broadcast viewers' purchasing behavior and shares a positive linear relationship with viewers' gift-giving behavior. Furthermore, broadcaster popularity significantly moderates the effect of social interaction-oriented content on viewers' purchasing and gift-giving behaviors.

Originality/value

This research enriches the literature on live-streaming commerce by investigating how social interaction-oriented content in broadcasters' live speech affects broadcast viewers' product-purchasing and gift-giving behaviors from the perspective of broadcast viewers' attention. Moreover, this study provides some practical guidelines for developing live speech content in the live-streaming commerce context.

Abstract

Purpose

Laser cladding deposition is limited in industrial application by the micro-defects and residual tensile stress for the thermal forming process, leading to lower fatigue strength compared with that of the forging. The purpose of this paper is to develop an approach to reduce stress and defects.

Design/methodology/approach

A hybrid process of laser cladding deposition and shot peening is presented to transform surface strengthening technology to the overall strengthening technology through layer-by-layer forming and achieve enhancement.

Findings

The results show that the surface stress of the sample formed by the hybrid process changed from tensile stress to compressive stress, and the surface compressive stress introduced could reach more than four times the surface tensile stress of the laser cladding sample. At the same time, internal micro-defects such as pores were reduced. The porosity of the sample formed by the hybrid process was reduced by 90.12% than that of the laser cladding sample, and the surface roughness was reduced by 43.16%.

Originality/value

The authors believe that the hybrid process proposed in this paper can significantly expand the potential application of laser cladding deposition by solving its limitations, promoting its efficiency and applicability in practical cases.

Abstract

Purpose

This study aims to the service life of TA15 alloy by solving the problem of the binding force between the matrix and AlTiSiN coating. The effect of a plasma nitriding (PN) interlayer on the magnetron-sputtered AlTiSiN coating was also investigated in detail.

Design/methodology/approach

The double-glow plasma alloying (DGPA) and magnetron sputtering (MS) techniques were combined as a new approach to realize a bilayer on TA15 consisting of an AlTiSiN layer with a PN interlayer. A TiN interlayer was formed via co-diffusion during the PN conducted at 1050°C for 3 h.

Findings

The PN interlayer can effectively improve the adhesion between coating and matrix; the PN/AlTiSiN coating presented excellent adhesion (80.1 N) and anti-wear property with a nano-hardness of 18.62 GPa. The resulting three-dimensional wear-track morphology exhibited a shallow depth and a narrow width.

Originality/value

The novel combination of the DGPA and MS technologies, using an infiltration layer rather than a coating one as the intermediate layer, can effectively enhance the adhesion between AlTiSiN coating and TA15 matrix. Meanwhile, the gradient layer can effectively improve both surface bearing and wear resistance.

Abstract

Purpose

Realizing project portfolio benefits (PPBs) is considered a key challenge faced by enterprises. This challenge can largely be attributed to an unclear understanding of the factors influencing PPBs. However, synergistic relationships create complexity for the management of influencing factors. In response to this dilemma, the objective of this study is to quantitatively investigate the factors influencing PPBs while considering the synergistic effect among factors to provide guidelines for benefits management.

Design/methodology/approach

Through an integration of the synergy degree of the composite system model and social network analysis (SNA), a refined model is proposed to explore the factors influencing PPBs. First, a list that includes financial and nonfinancial influencing factors is clarified. Then, the corresponding network links, which represent the synergistic relationships among the factors, are innovatively assessed based on the synergy degree of the composite system. Finally, the influencing factor network is analyzed using both individual and overall indicators of SNA.

Findings

The resulting evidence demonstrates that four critical influencing factors exist, namely, “project managers,” “purchasers,” “development capacity” and “tangible resources.” These factors are relatively important and should be prioritized. Furthermore, the factors are divided into three subgroups: participant, resource and governmental factors. A general observation from the results is that factors that share the same subgroup are more likely to have a synergistic effect advantage, which leads to an increase in PPBs.

Originality/value

The value of this paper lies in its proposition of a quantitative model that can be used to measure and analyze the factors influencing PPBs with synergy considerations. This research contributes to the body of knowledge on benefits management by linking synergy with PPBs. It presents new insights for managers on how PPBs may be effectively managed and promoted from the perspective of influencing factors.

Abstract

Purpose

This study aims to explore the influence of science fiction on innovators and present a comprehensive model using the theory of planned behavior and social support theory to discuss the impact of science fiction on the intention of becoming an innovation worker.

Design/methodology/approach

Partial least squares structural equation modeling (PLS-SEM) was adopted in this study and responses were obtained from 244 Chinese innovators.

Findings

The results revealed the adequacy of the proposed model and the above-mentioned constructs in explaining innovation intention. Science fiction perception was found to influence the intention of becoming an innovation worker directly. Subjective norm, perceived behavioral control, and attitude directly influence the intention of becoming an innovation worker. Additionally, attitude is a mediator between science fiction perception and the intention of becoming an innovation worker. Moreover, social support network moderates the relationship between attitude and intention.

Originality/value

These results shed light on the mechanism by which science fiction influence innovators as well as provide critical managerial implications for policymakers and practitioners.
