Abstract

Purpose

The purpose of this paper is to promote the efficiency of RGB-depth (RGB-D)-based object recognition in robot vision and find discriminative binary representations for RGB-D based objects.

Design/methodology/approach

To promote the efficiency of RGB-D-based object recognition in robot vision, this paper applies hashing methods to RGB-D-based object recognition by utilizing the approximate nearest neighbors (ANN) to vote for the final result. To improve the object recognition accuracy in robot vision, an “Encoding+Selection” binary representation generation pattern is proposed. “Encoding+Selection” pattern can generate more discriminative binary representations for RGB-D-based objects. Moreover, label information is utilized to enhance the discrimination of each bit, which guarantees that the most discriminative bits can be selected.

Findings

The experiment results validate that the ANN-based voting recognition method is more efficient and effective compared to traditional recognition method in RGB-D-based object recognition for robot vision. Moreover, the effectiveness of the proposed bit selection method is also validated to be effective.

Originality/value

Hashing learning is applied to RGB-D-based object recognition, which significantly promotes the recognition efficiency for robot vision while maintaining high recognition accuracy. Besides, the “Encoding+Selection” pattern is utilized in the process of binary encoding, which effectively enhances the discrimination of binary representations for objects.

The purpose of this paper is to investigate the tribological properties of the WC/TiC-Co substrate under different loading conditions under three impact abrasive wear conditions.

Abstract

Purpose

The purpose of this paper is to investigate the tribological properties of the WC/TiC-Co substrate under different loading conditions under three impact abrasive wear conditions.

Design/methodology/approach

The three body collisional wear behavior of Co alloy with WC and TiC at three impact energy was studied from 1 to 3 J. Meanwhile, the microstructure, hardness, phase transformation and wear behavior of these specimens were investigated by scanning electron microscopy, Rockwell hardness (HRV), EDS and impact wear tester. The resulting wear rate was quantified by electronic balance measurements under different pressures.

Findings

The specific wear rate increases with the increase of the nonlinearity of the impact energy and the increase in the content of WC or TiC. The effect of TiC on wear rate is greater than that of WC, but the hardness is smaller. The wear characteristics of the samples are mainly characterized by three kinds of behavior, such as cutting wear, abrasive wear and strain fatigue wear. The WC-Co with fewer TiC samples suffered heavier abrasive wear than the more TiC samples under both low and high impact energy and underwent fewer strain fatigue wears under high impact energy.

Originality/value

The experimental results show that the wear resistance of the Co alloy is improved effectively and the excellent impact wear performance is achieved. The results can be used in cutting tools such as coal mine cutting machines or other fields.

Abstract

Purpose

The purpose of this paper is to investigate the effects of original equipment manufacturing suppliers’ local network embeddedness on buyers’ relative attention and joint innovation through service innovation competence.

Design/methodology/approach

A structural equation model was analyzed using AMOS 21 with data derived from 165 buyers in the Taiwanese electronics industry.

Findings

From the buyer perspective, suppliers with embedded network relationships in emerging markets are perceived to be service oriented and to have relative attention and joint innovation that are attractive to buyers. In addition, the findings of empirical testing conducted in this study suggest that perceived exploitative and explorative service innovation competence partially mediate the relationship between perceived network embeddedness and relative attention, while explorative service innovation competence partially mediates the influence of perceived network embeddedness on buyers’ joint innovation.

Originality/value

This study innovatively employed a buyer perspective to examine the servitization of manufacturing suppliers and the effects of this on the buyer–supplier relationship, providing new insights into the role of service innovation competence as well as important theoretical and managerial implications.

Abstract

Purpose

Original equipment manufacturing (OEM) suppliers must identify and communicate competences to ensure that they are successfully translated into competitive advantages. This study aims to explore the competence-based marketing capabilities of suppliers based on competence-based marketing view. It integrates resource-based theory and resource dependence theory to conduct a detailed evaluation of the impact of competence-based marketing capabilities on collaboration development, which is classified as either exploitative or explorative collaboration between buyers and suppliers.

Design/methodology/approach

The partial least squares method was used to analyse and find direct support for the authors’ hypotheses based on cross-sectional data from a sample of 116 Taiwanese OEM suppliers.

Findings

The results find no support as recent arguments that the marketing of competence would directly affect collaborative relationships in a buyer–supplier relationship. The two mediating roles of relative attention from buyers and relationship learning with buyers were confirmed. The empirical findings indicated that relative attention from buyers partially mediates the relationship between competence-based marketing capabilities and exploitative collaboration development, while relationship learning completely mediates the relationship between competence-based marketing capabilities and two-pronged collaboration development.

Originality/value

This study provides a thorough examination of competence-based marketing capabilities, which have attracted substantial attention from business scholars but empirical research investigating and discussing how suppliers develop new collaborations with buyers is lacking.

Abstract

Purpose

The purpose of this paper is to identify different automotive coatings using Confocal Raman microscope which could hardly be differentiated with Fourier transform infrared microscope (FTIR).

Design/methodology/approach

Raman spectroscopy was used to provide extra vibration information to infrared spectroscopy. Paints preparation was not necessary, and only 30 s was needed for each sample in an optimised method. Paints were first analysed by FTIR and then compared with Raman microscope.

Findings

Raman microscope was used to address the lack of ability of FTIR in discriminating four groups of paints in same colours. This study indicated that Raman microscopy is especially effective in sensing pigments and could successfully identify all pigments in the paints.

Research limitations/implications

The two instruments in combination produce accurate results than when used individually, especially in complex and multi-layered paints analysis.

Practical implications

The method proved to be fast, accurate and non-destructive, and it could be easily applied to real cases.

Originality/value

With this method, scientists could discriminate some coating types which were hard to be discriminated by other techniques.

Abstract

Purpose

While service innovation is an important issue for manufacturers, relatively little research lends empirical support to the perspective that service innovation enhanced by collaborative competence may impact the competitive advantage of original equipment manufacturing (OEM) suppliers. This study aims to advance a service-dominant logic by empirically investigating the linkage between collaborative competence, service innovation and competitive advantage for OEM suppliers.

Design/methodology/approach

Surveys were completed by representatives of 142 Taiwanese OEM suppliers in the electronics industry.

Findings

The results of path analysis suggest that information competence and coordination competence have positive effects on both exploitative service innovation and explorative service innovation. There only appears to be a significant relationship between joint innovation competence and explorative service innovation. Furthermore, two-pronged service innovations contribute to a supplier’s internal and external competitive advantage.

Originality/value

The empirical findings have important research and practical implications that help elucidate the antecedents and outcomes of OEM suppliers’ service innovation.

Abstract

Purpose

Entrepreneurial mentoring is widely regarded as an effective way to train novice entrepreneurs all over the world. However, the effectiveness of this approach and the determinants are not well understood under country-specific conditions. The purpose of this paper is to build a conceptual framework and use empirical analysis to explore the mentoring effect and its determinants, especially in the Chinese context.

Design/methodology/approach

The paper uses data from 172 young entrepreneurs which had been supported by Youth Business China, Mianyang Office since 2008. The factor analysis and structural equation model have been applied to analyze the data to investigate the quantitative relationship and path of the mentoring effect of entrepreneurship with mentor’s factors, young entrepreneurs (mentees’s factors) and their interrelationship.

Findings

The assessment scores of the entrepreneurship mentoring effect both in experience level and effectiveness level are relatively high, in the satisfactory range. The entrepreneurship mentoring effect, measured by the experience and the performance level, is determined by the coupling interaction of the mentor, the mentee and their interactive relationship. Among them, the mentor’s characteristic, the most important being his/her intention, has the biggest effect on the mentoring effect, significantly bigger than the mentor’s quality and skill. However, the mentor’s intention is not strong as expected. The interactive relationship between the mentor and the mentee also has a significant positive effect on entrepreneurial mentoring effect. The study also discovered the mentee factors have comparatively smaller effect on both the interactive relationship and the mentoring effect. Furthermore, it is found that the absorptive capability and learning intention of the young entrepreneur are relatively weak.

Research limitations/implications

The construction of the index system of this research reflects the overall characteristics of the research objects and their static relationships. Therefore, the dynamic change of the mentoring relationship in different phases of the mentorship has not been taken into account. Also, self-serving bias may exist as this research measures the mentoring effect by the feedback on the mentor’s perception, using surveys completed by the mentees to measure both the mentee’s traits and the mentor’s qualities.

Practical implications

This study provides guidance on how entrepreneurship could be promoted and on how educational institutions in China can make the mentoring process a positive and effective system in order to enhance the mentoring effect.

Social implications

The empirical conclusions of the present study can be applied to other business incubator, entrepreneurship education institutions and for the improvement and promotion of entrepreneurial mentoring system in China.

Originality/value

This paper probes into the mentoring system in the context of China from a new perspective and proposes an original conceptual model to study the entrepreneurship mentoring effect and its determinant.

Abstract

Purpose

The purpose of this paper is to examine the mediating effect of job autonomy on the relationship between direct supervisor’s transformational leadership behaviors and employees’ extended use of information technologies (IT). In addition, this study considers IT innovativeness as a significant moderator in the research model, in order to examine if the relative influences of leadership behaviors on IT extended use are contingent upon employees’ IT innovativeness.

Design/methodology/approach

A field survey was conducted in China and empirical data were collected from 299 employees who use IT in support of daily work. Structural equation modeling technique was used to examine the research model and corresponding hypotheses.

Findings

The empirical results indicate that: three dimensions of transformational leadership, specifically interpersonal consideration, intellectual stimulation and inspirational motivation, are significant antecedents of employees’ IT extended use; perceived job autonomy partially mediates the relationships between transformational leadership behaviors and IT extended use; and employees’ IT innovativeness positively moderates the effects of transformational leadership behaviors on IT extended use.

Practical implications

This study can provide first-line managers with a better understanding of how to stimulate employees to make an extended use of IT by granting them more freedom in job assignments. Furthermore, the managers also need attend to subordinates’ personal IT innovativeness when exhibiting transformational leadership behaviors.

Originality/value

This study contributes to the extant literature of IT extended use through the lens of transformational leadership and job characteristics theory. In particular, this study identifies the boundary condition of the proposed research model by uncovering the moderating effect of IT innovativeness between transformational leadership behaviors and IT extended use.

Abstract

Purpose

The purpose of this paper is to examine the impacts of research and development (R&D) investment and environmental, social and governance (ESG) performance on green innovation performance. This paper also investigates the moderating effect of ESG performance between R&D investment and green innovation performance.

Design/methodology/approach

The study uses the data of 223 Chinese listed companies over the period 2015–2018. The ESG indices issued by SynTao Green Finance are used to measure ESG performance. Green innovation performance is measured by the total number of green patents, the number of green invention patents and the number of green non-invention patents. Finally, multiple regression analysis is applied to test the research hypotheses.

Findings

The results show that R&D investment has a positive impact on green innovation performance and ESG performance can increase the number of green invention patents. In addition, ESG performance moderates the relationship between R&D investment and green innovation performance.

Practical implications

The findings may help managers and policymakers in developing countries to make ecological innovation strategies to achieve corporate sustainability.

Originality/value

This is the first study to examine the impacts of R&D investment and ESG performance on green innovation performance in the context of China, an emerging market.
