Abstract

Purpose

The purpose of this paper is to evaluate the wear performance of carbon steel cladded with TiC powders by gas tungsten arc welding method. Because of poor wear resistance, carbon steels have limited industrial applications as tribological components.

Design/methodology/approach

The cladding microstructures were characterized by optical microscope, scanning electron microscope (SEM) and X-ray energy dispersive spectrometer. The wear behavior of the clad layer was studied with a block-on-ring tribometer.

Findings

The experimental results revealed that the metallurgical interface provided an excellent bond between the cladding and the carbon steel substrate. The cladding revealed no porosity or cracking, and particles were evenly distributed throughout the cladding layer. Hardness was increased from HRc 6.6 in the substrate to HRc 62 in the cladded layer due to the presence of the hard TiC phase.

Originality/value

The experiments confirm that the cladding surfaces of TiC particles reduce wear rate and friction. Increasing TiC contents also improves hardness and wear resistance at room temperature and under dry sliding wear conditions.

Abstract

Purpose

This paper aims to provide an improved multifractal method to extract the pavement cracks in the complicated background. Furthermore, the pavement surface images with or without crack can also be distinguished by this method.

Design/methodology/approach

The framework of analyzing the image singularity is based on the sub‐pixel multifractal measure (SPMM). Performing the SPMM can give the sub‐pixel local distribution of the image gradient and a more precise singularity exponent distribution in the image. Meantime, using the singularity exponents and the most singular manifold (MSM), the image can be decomposed into a series of sets with different statistical and physical properties automatically and easily. One can extract the cracks according to the MSM.

Findings

The example shows that the physical and geometrical properties of the pavement images can be obtained by analyzing the distribution of singularity exponents and the greatest singularity exponent. The simulation results show that the SPMM has higher quality factor in the image edge detection. And the MSM detected this way reflects the most important information of the image.

Originality/value

Performing the SPMM can give a more precise singularity exponent distribution in the image.

Abstract

Purpose

This study aims to identify a value co-creation framework for live streaming through tourism scenes (LStTS). It also clarifies the value attributes of LStTS and makes an empirical test.

Design/methodology/approach

The study used a mixed-method approach. In Study 1, a total of 12,216 pieces of viewers’ comments and ten web news reports were coded and analyzed employing a grounded theory approach. In Study 2, data were collected from 587 Douyin e-commerce users. Exploratory factor analysis and partial least squares structural equation modeling were used to test the value co-creation framework of LStTS.

Findings

In Study 1, six value attributes in three categories were identified based on a content analysis of viewers’ comments. In Study 2, a three-order factorial model of value co-creation in LStTS was identified and tested.

Research limitations/implications

Our study is limited by the preponderance of female respondents in the sample and the unique nature of the research context.

Practical implications

Merchants and streamers should consider whether there is a fit between the merchandise and the tourism scene when selecting the tourism scene for live streaming marketing; they can select novel and beautiful natural tourism scenes to attract viewers. Detailed and comprehensive product information should be provided in the process of live streaming marketing and sharing with consumers.

Originality/value

The novelty of our study lies in the provision of a new value co-creation framework in LStTS, which offers a theoretical basis for analyzing the value of the tourism scene in live streaming marketing.

Abstract

Purpose

The purpose of this study is to help governments make carbon-tax policy and help enterprises make decisions under that policy.

Design/methodology/approach

Based on the carbon-tax policy, with the consideration of consumers’ low-carbon preferences, this paper compares the pricing, emission reduction and advertising decisions in three different games (one centralized game and two decentralized Stackelberg games).

Findings

This paper concludes that, through centralized game, namely, cooperation game, manufacturers, retailers and consumers can reach their optimal situation. In the numerical simulation, this paper analyzes the impact of carbon-tax rate to the decisions of manufacturer and retailer, as well as their profit.

Originality/value

Using the Nash Bargaining Model, the introduction of the bargaining power and the degree of risk aversion of the parties, this study provides some solution for the distribution of the additional profit when they cooperate, in which way they can reach their Pareto optimality.

Abstract

Purpose

The purpose of this paper is to briefly summarize and review the theories and methods of complex structures’ dynamic reliability. Complex structures are usually assembled from multiple components and subjected to time-varying loads of aerodynamic, structural, thermal and other physical fields; its reliability analysis is of great significance to ensure the safe operation of large-scale equipment such as aviation and machinery.

Design/methodology/approach

In this paper for the single-objective dynamic reliability analysis of complex structures, the calculation can be categorized into Monte Carlo (MC), outcrossing rate, envelope functions and extreme value methods. The series-parallel and expansion methods, multi-extremum surrogate models and decomposed-coordinated surrogate models are summarized for the multiobjective dynamic reliability analysis of complex structures.

Findings

The numerical complex compound function and turbine blisk are used as examples to illustrate the performance of single-objective and multiobjective dynamic reliability analysis methods. Then the future development direction of dynamic reliability analysis of complex structures is prospected.

Originality/value

The paper provides a useful reference for further theoretical research and engineering application.

Abstract

Purpose

The purpose of this study is to empirically explore the relationship between a new venture top management team's (NVTMT’s) shared leadership and strategic performance in opportunity recognition and entrepreneurial bricolage by drawing on the upper echelons theory.

Design/methodology/approach

Data were collected from 344 new manufacturing ventures located in Eastern China. The hypotheses were tested using structural equation modelling (SEM) through the AMOS 23.0 software package. The confluence of the contextual factors of the new venture is examined by a fuzzy-set qualitative comparative analysis (fsQCA).

Findings

The results indicate that NVTMT shared leadership has an indirect and positive effect on strategic performance through opportunity recognition, especially in a highly uncertain environment, while the mediating effect of entrepreneurial bricolage is not significant. Furthermore, although the SEM results show that the impact of NVTMT shared leadership on entrepreneurial bricolage is negative, the fsQCA shows that NVTMT shared leadership can significantly and positively affect entrepreneurial bricolage in an environment with high uncertainty, ultimately enhancing strategic performance.

Originality/value

This study contributes to the shared leadership literature by proposing a model on how shared leadership shapes the strategic performance of new ventures via opportunity recognition and entrepreneurial bricolage. The findings not only enrich relevant research on the upper echelons theory, but also help in understanding the patterns of contextual conditions that facilitate the value-adding properties of NVTMT shared leadership.

Abstract

Purpose

This study empirically explores how firms configure the strength and the temporal and spatial features of corporate volunteering (CV) events to promote corporate reputation (CR).

Design/methodology/approach

Using event system theory as a framework and applying fuzzy-set qualitative comparative analysis (fsQCA) to 385 firms and 2,783 public respondents, this study explores the configurational effects of five elements of CV events—employee engagement, customer engagement, meagre incentive, duration and scope of influence—on two types of CR: capability reputation (CAR) and character reputation (CHR).

Findings

The results indicate that (1) the impact of volunteering on CR is not only configurational in nature, but also characterised by equifinality (i.e. the presence of multiple paths to success); (2) with meagre incentive and in the absence of scope-of-influence support, long-term employee and customer engagement in CV is sufficient to achieve high CAR; (3) adequate and diverse incentives, high employee engagement and a sufficiently broad scope of influence work well with either high customer engagement or long duration to achieve high CAR and CHR, respectively; (4) there are identical configurations that can achieve high CAR and CHR.

Originality/value

This study contributes to the CV and CR literature by extending the application of event system theory to proactive events.

Abstract

Purpose

The purpose of this study is to empirically explore how firms configure centrifugal and centripetal forces in promoting breakthrough innovation (BI), thus improving their strategic performance (SP) in the artificial intelligence (AI) context.

Design/methodology/approach

This study applies the centrifugal and centripetal forces model to a survey sample of 285 Chinese AI firms. Fuzzy-set qualitative comparative analysis (fsQCA) and propensity score matching (PSM) are integrated to explore the configurational effects of three centrifugal forces—the autonomy of technical experts, knowledge search and alliance network—and two centripetal forces—strictness of organisational institutions (SOI) and human–human–AI collaboration (HHAC)—on BI, examining whether the configurations that enhance BI can further improve SP.

Findings

The results indicate that the strictness of innovation institutions (SII) and strictness of ethical institutions (SEI) are equally important for determining SOI. Three configurations can improve BI when SOI and HHAC are the core conditions; only one of three configurations can further improve SP significantly.

Originality/value

By introducing SOI composed of equally important levels of SII and SEI and HHAC, this research is one of the few empirical studies to explore the mechanisms behind the impact of centrifugal and centripetal forces on BI and SP, which may help researchers and managers address innovation challenges in the AI context.

Abstract

Purpose

This study aims to explore how information technology (IT) companies that provide professional information systems/IT solutions to business clients can enhance employees’ service innovation performance.

Design/methodology/approach

Self-reported data were collected from 251 employees over two periods, along with their supervisor-reported data. The model was tested using structural equation modeling.

Findings

Employees’ engagement fully mediates the impact of innovative self-efficacy and social identification on service innovation performance. Employees’ customer orientation and feeling trusted both strengthen the transformation of service innovation engagement into service innovation performance. However, IT employees’ embeddedness, unexpectedly, significantly weakens the link between engagement and performance in business-to-business (B2B) service innovation contexts.

Research limitations/implications

The sample was collected in Taiwan, where the IT industry is dominant and employees’ values and team interactions are influenced by Chinese culture. Data drawn from a single industry, involving a particular culture, limit claims of external validity.

Practical implications

Managers can encourage participative decision-making, or hold official platforms where peers and clients can exchange ideas, leading to higher levels of feeling trusted and customer orientation, which both strengthen the link between service innovation engagement and performance. Moreover, highly embedded members can easily discuss novel ideas with team members and obtain improvement-oriented feedback, which ensures highly embedded members can keep focusing on service innovation.

Originality/value

This study provides a more nuanced picture of predictive factors for individual innovation behavior in B2B service innovation contexts in which employees provide business clients with professional, innovative IT solutions through team-based projects.

Abstract

Purpose

This paper aims to answer how corporate governance and corporate social responsibility (“CSR”) affect the relationship between value creation and tax avoidance. This study further analyses the impact of the institutional environment, i.e. whether a country is rather a liberal or a coordinated market economy, on the relationship between CSR and tax avoidance.

Design/methodology/approach

The empirical analysis comprises a panel data set of 7,924 observations for the years from 2005 to 2014 for European companies. The relationship between value creation and tax avoidance is tested by grouping the sample in high and low CSR performers. Similarly, the impact of the type of market economy is analysed for the firms.

Findings

The research design does not find evidence that tax avoidance is creating value. The empirical findings reveal that there is a positive relationship between value creation and the effective tax rate for firms with low social and environmental characteristics. Further, this analysis could show that stronger corporate governance is associated with a lower effective tax rate in both coordinated and liberal market economies. The analysis identifies social strengths being associated with a higher effective tax rate for coordinated market economies.

Practical implications

It is proposed to encourage CSR disclosure. The creation of incentives for social strengths could increase tax revenue. Firms should reconsider whether the engagement in tax avoidance is worth it and pursue social responsibility to achieve higher value creation for their stakeholders.

Originality/value

The paper challenges the intuitive expectation that tax avoidance creates value. It is suggested that the governance and CSR culture, as well as the tax legislation in Europe, is different to the USA. Conclusively, tax avoidance is not generating value for the European sample.
