Abstract

Purpose

Competitor analysis is a key component in operations management. Most business decisions are rooted in the analysis of rival products inferred from market structure. Relative to more traditional competitor analysis methods, the purpose of this paper is to provide operations managers with an innovative tool to monitor a firm’s market position and competitors in real time at higher resolution and lower cost than more traditional competitor analysis methods.

Design/methodology/approach

The authors combine the techniques of Web Crawler, Natural Language Processing and Machine Learning algorithms with data visualization to develop a big data competitor-analysis system that informs operations managers about competitors and meaningful relationships among them. The authors illustrate the approach using the fitness mobile app business.

Findings

The study shows that the system supports operational decision making both descriptively and prescriptively. In particular, the innovative probabilistic topic modeling algorithm combined with conventional multidimensional scaling, product feature comparison and market structure analyses reveal an app’s position in relation to its peers. The authors also develop a user segment overlapping index based on user’s social media data. The authors combine this new index with the product functionality similarity index to map indirect and direct competitors with and without user lock-in.

Originality/value

The approach improves on previous approaches by fully automating information extraction from multiple online sources. The authors believe this is the first system of its kind. With limited human intervention, the methodology can easily be adapted to different settings, giving quicker, more reliable real-time results. The approach is also cost effective for market analysis projects covering different data sources.

Abstract

Purpose

Burnout among first-line police in China is high. The purpose of this paper is to examine the relationship between feedback environment, feedback orientation, psychological empowerment, and burnout as related to the police work.

Design/methodology/approach

An empirical study was conducted with a sample of 437 basic-level policemen and policewomen in the Shandong province of China. Participants completed a series of questionnaires including the supervisor feedback environment scale, feedback orientation scale, psychological empowerment scale, and the Maslach Burnout Inventory.

Findings

The results indicate that police supervisor feedback environment is negatively related to burnout. The relationship between the supervisor feedback environment and burnout is perfectly mediated by psychological empowerment and significantly moderated by feedback orientation. The mediation effect of psychological empowerment is significantly influenced by feedback orientation.

Originality/value

The findings have contributed to answering several recent questions in the feedback-burnout literature. The authors stress that leaders should strive to build a supportive feedback environment for employees.

Abstract

Purpose

The tribological behavior, i.e. friction coefficient and wear rate, and vibration characteristics of the water-lubricated bearing was investigated. The water-lubricated bearing is made of three different materials, i.e. polyether-ether-ketone (PEEK), polyimide (PI) and nitrile-butadiene rubber (NBR).

Design/methodology/approach

The tribological behavior was investigated experimentally on a specially designed test rig. Three vibration sensors were used to record the vibration of the bearing.

Findings

The results indicated that the variation of friction coefficient with rotation speed agrees well with the trend of Stribeck curve. The tested friction coefficient of rubber bearing is higher than that of the other two bearings whether it is in the state of mixed-lubrication or hydrodynamic lubrication, and which causing a larger wear rate in rubber bearing. The PEEK bearing exhibits the best tribological properties due to it has smaller friction coefficient and wear rate. However, it can be found that the rubber bearing gives the minimum vibration acceleration, which means that the rubber bearing has the most potential to improve the stability of water-lubricated bearing rotor system.

Originality/value

In this study, a group of experiment studies conducted on a specially designed test rig. The comprehensive performance, including friction coefficient, vibration acceleration and wear rate, of water-lubricated bearing with three different materials, i.e. PEEK, PI and NBR, was compared systematically. The experiment research may offer a reference for the selection of material in water-lubricated bearing in specific operating conditions.

Abstract

Purpose

This paper aims to explore the possibility of converting the nitrile butadiene rubber (NBR) water-lubricated bearing material into a self-lubricating bearing material by the action of polytetrafluoroethylene (PTFE) particles and water lubrication.

Design/methodology/approach

A group of experimental studies was carried out on a ring-on-block friction test. The physical properties, tribological properties and interface structure of PTFE-NBR self-lubricating composites filled with different percentages of PTFE particles were investigated.

Findings

The experimental results indicated that the reduction in friction and wear is a result of the formation of the lubricating film on the surface of the composites. The lubricating film was formed of a large amount of PTFE particles continuously supplied under water lubrication conditions and the PTFE particles here can greatly enhance the load capacity and lubrication performance.

Originality/value

In this study, the tribological properties of PTFE particles added to the NBR water-lubricated bearing materials under water lubrication were investigated experimentally, and the research was carried out by a ring-on-block friction test. It is believed that this study can provide some guidance for the application of PTFE-NBR self-lubricating.

Abstract

Purpose

The purpose of this study is to clarify the effects of transformational leadership (TL) on radical and incremental innovation through the mediating roles of knowledge sharing (KS) behaviors. This study also attempts to bring deeper insight of the correlation among the latent factors by examining how knowledge-centered culture (KCC) moderates the effects of TL on KS behaviors and innovation capability.

Design/methodology/approach

This study conducts a questionnaire survey and Structural Equation Modeling to test the proposal research model based on a sample of 321 participants in 85 service and manufacturing firms.

Findings

The results revealed that KS behaviors significantly mediate the relationship between TL and two types of innovation. Specifically, knowledge collecting has more significant effect on incremental innovation compared with influence of knowledge donating. By contrast, knowledge donating has a greater effect on radical innovation compared with effect of knowledge collecting. The paper also highlights the important role of KCC in enhancing the effects of TL on KS activities and innovation capabilities.

Research limitations/implications

The study has highlighted the important role of KCC as it positively moderates the influences of TL on KS and innovation capability.

Practical implications

The study provides evidence that TL style is the main driving force of KS processes. Managers should prioritize practicing this leadership style to improve employees' KS behaviors and firm's innovation capability.

Originality/value

The study significantly fills the gaps in the literature that emphasizes how KS behaviors induce different impacts on specific aspects of innovation capability. By exploring the moderator of KCC, the paper significantly contributes to advancing the understanding of how transformational leaders foster employees' KS behaviors for improving radical and incremental innovation.

Abstract

Purpose

Although the concept of branding has been considered extensively in products and services, branding in Chinese is a relatively emerging phenomenon. This paper aims to present the enlivenment of branding in Chinese within the cross‐strait markets of Taiwan and Mainland China, which underlies various ideologies.

Design/methodology/approach

This study primarily reviews literatures of brand and brand name translation, defines the essentiality of brand naming, and outlines the branding strategies for entering cross‐strait markets. Furthermore, this study validates the using of substantially interpreted brands that support the authors' four developed propositions.

Findings

This study compares substantially interpreted brands in cross‐strait markets with a reference to commonly used translation methods. The results illustrate interesting ideologies among cross‐strait markets and can help managers achieve global brand recognition.

Research limitations/implications

Since China and Taiwan share the same Chinese culture, the qualitative method proposed by the present authors is more applicable to practitioners who are eager to pursue branding in cross‐strait markets. Thus, the relevant techniques may not be applicable to people less familiar with Chinese culture.

Practical implications

The qualitative case study provides an advisable method for branding in Chinese. The results of this study can provide greater understanding of the various ideologies in cross‐strait markets, as well as help managers achieve global brand recognition.

Originality/value

The various ideologies from branding is complex, especially for those involved with linguistic essentials. Previous research has mainly focused on managerial‐based branding and customer‐based branding. This paper extends the interest into enlivening inspirations.

Abstract

Purpose

Based on DNase I and reduced graphene oxide (rGO)-magnetic silicon microspheres (MNPS), a highly sensitive and selective fluorescent probe for the detection of PD-L1 was developed.

Design/methodology/approach

Here °C we present a feasibility of biosensor to detection of PD-L1 in lung tumors plasma. In the absence of PD-L1°C the PD-L1 aptamer is absorbed on the surface of graphene oxide modified magnetic nanoparticles °8rGO-MNPS°9 and leading to effective fluorescence quenching. Upon adding PD-L1°C the aptamer sequences could be specifically recognized by PD-L1 and the aptamer/PD-L1 complex is formed°C resulting in the recovery of quenched fluorescence.

Findings

This sensor can detect PD-L1 with a linear range from 100 pg mL−1 to 100 ng mL−1, and a detection limit of 10 pg•m−1 was achieved.

Originality/value

This method provides an easy and sensitive method for the detection of PD-L1 and will be beneficial to the early diagnosis and prognosis of tumors.

Abstract

Purpose

Given the important role of frugal innovation for firms in the developing and emerging countries, the purpose of this paper is to investigate the effect of transformational leadership (TL) on frugal innovation through the mediating roles of tacit and explicit knowledge sharing.

Design/methodology/approach

The paper used a quantitative research method and structural equation modeling to test the relationship among the latent factors based on a sample of 339 participants from 120 Vietnamese firms.

Findings

Findings reveal the significant impacts of TL on aspects of frugal innovation, namely, frugal functionality, frugal cost and frugal ecosystem. Moreover, the paper highlights the mediating roles of tacit and explicit knowledge sharing (KS) in the relationship between TL and frugal innovation in terms of frugal functionality and frugal cost.

Research limitations/implications

To bring a deeper understanding of the benefits and important role of knowledge resources, future research should investigate the potential mediating mechanisms of knowledge management processes in the relationship between specific leadership styles and frugal innovation.

Practical implications

The paper provides a valuable understanding and novel approach for managers and directors of firms in developing and emerging countries to improve their firms’ frugal innovation capability through leadership practice and knowledge resources.

Originality/value

Abstract

Purpose

This paper aims to find the endogenous relationship between innovation input and corporate performance and deepen the study of innovation performance theory in industry and enterprise at the micro level.

Design/methodology/approach

This paper selects the firms listed on A shares in Shanghai and Shenzhen Stock Exchanges from 2009 to 2015 as samples. The authors cluster these samples according to the factors of production and classify the samples into three types: technology-intensive, capital-intensive and labor-intensive. After obtaining the samples and classifying them, the authors conduct a research on the endogenous relationship between the innovation input and the corporate performance through the simultaneous equations model and 3SLS estimation method. Meanwhile, they also make a study on the influence of executive incentive mechanism on the relationship between the innovation input and the corporate performance.

Findings

In technology-intensive industry, the increase of pre-innovation input will enhance the corporate performance in the current period, however, which will slow down the pace of innovation and lead to lower corporate performance in the future, and then increase innovation input again. In contrast, in capital-intensive industries, innovation input just improves corporate performance in the current period and the promotion of corporate performance will promote the intensity of innovation input in the future. With labor-intensive industries, innovation input also depends on early good returns, but innovation input has no significant impact on the corporate performance both at present and in the future. While in the executive incentive mechanism, salary incentive has a significant positive regulatory effect on the relationship between innovation input and corporate performance.

Originality/value

This paper presents a new research perspective on the relationship between innovation input and firm corporate performance, which is of great value to the listed company in balancing the R&D input with the company’s target performance and the design of executive incentive mechanism.
