Abstract

Purpose

The purpose of this paper is to construct a novel grey incidence evaluation model to investigate a scientific and effective evaluation system of regional road traffic safety.

Design/methodology/approach

To provide a method for the evaluation of regional road traffic safety, the grey incidence feature vector method is employed to construct the evaluation index system for regional road traffic safety and then the index weights are calculated with Shannon entropy method. In this paper, the grey incidence feature vector method and grey incidence analysis are utilised to construct evaluation index systems for regional road traffic safety and determine the index weights. Then a grey incidence-ideal point method is used to establish a novel evaluation model for regional road traffic safety. To thoroughly investigate the road traffic safety in one region, the data of 13 cities in Jiangsu province is gathered, using the grey clustering and grey incidence-ideal point method to obtain the ranking results of the 13 cities.

Findings

The results provide a basic analysis of the present situation and show the differences for these regions based on the proposed model, according to which several solutions are proposed, aiming to improve regional road traffic safety situation.

Practical implications

The method exposed in the paper can be used to deal with the problems of the evaluation of regional road traffic safety.

Originality/value

The paper succeeds in understanding the status quo and implementing effective road traffic safety management based on the proposed model.

Abstract

Purpose

This study aims to develop a new kind of functional low molecular weight organic dyes, which is highly efficient, meanwhile inexpensive and easily prepared and modified and can be used in photoacoustic (PA) imaging and photothermal therapy (PTT). To further realize the release of molecules under the biomedical condition, the releasing efficiency of micellar nanoparticles under different stimuli were represented.

Design/methodology/approach

A class of azo and Schiff base derivatives with different click reagents were characterized by PA imaging and photothermal (PT) experiments. The molecule with best PT effect was loaded into a temperature-stimuli-sensitive amphiphilic block copolymer which demonstrated the capability of releasing the polymers under the near-infrared (NIR) light of 650 nm.

Findings

The PA and PT effects of a series of azo and Schiff base derivatives with different click reagents were characterized. Introducing the click reagent F4-TCNQ can result in red shift of peaks of PA intensity. Stimulated with 650 nm laser irradiation, the polymer processed higher release rate than being stimulated by temperature stimuli.

Practical implications

This paper not only guides the design of NIR dyes with good PA intensity but also provides a method which has great potential for the application of NIR photothermal dyes in the field of biotechnology for controlled release.

Originality/value

This paper uses click reagents to modify azo and Schiff derivatives and an amphiphilic block copolymer under NIR light to realize controlled release.

Abstract

Purpose

Currently, conjugated nonlinear optical (NLO) materials suffer from the drawbacks of complex manufacturing process and high cost. To further study the NLO materials with cost-effective, it is necessary to prepare new NLO materials with satisfactory performance.

Design/methodology/approach

Pyrene derivatives with good third-order NLO properties were synthesized by combining pyrene compounds with TCNE, TCNQ, F4-TCNQ and other molecular systems by clicking chemical method.

Findings

The pyrene derivatives were characterized by ultraviolet spectrum and Z-scan. The charge-transfer of the D-p-A structures plays a key role in the absorption peak shifts. And the third-order nonlinear absorption of the products revealed good third-order NLO susceptibilities.

Research limitations/implications

The synthesis technology of pyrene derivatives is not mature enough and is in the preliminary exploration stage. So, the authors produced a relatively small number of samples and did not conduct a very comprehensive test.

Practical implications

This novel pyrene derivative is suggestive and can promote the exploration and development of the third-order nonlinear materials.

Originality/value

Four new pyrene derivatives were synthesized by selecting new molecular systems. Because of its good chemical properties and stable properties, it can be a reference for the development of third-order nonlinear materials in the future.

Abstract

Purpose

In this paper, the authors study the production and pricing decisions of a remanufacturing supply chain composed of a supplier, an assembler and a remanufacturer, in which the remanufacturing of components requires patent licensing from the supplier.

Design/methodology/approach

The authors consider three different models with government subsidy for remanufacturing: (1) no government subsidies; (2) the government subsidizes the remanufacturing behavior of the supplier and (3) the government subsidizes the remanufacturing behavior of the remanufacturer and use the Stackelberg game model to solve and analyze the equilibrium wholesale prices of components and the equilibrium outputs of new and remanufactured products under three subsidy modes.

Findings

The results show that the equilibrium wholesale prices of two kinds of components decrease with the unit patent licensing fee and the unit government subsidy, and the equilibrium quantity of the remanufactured products under the three modes is obviously higher than that of the new products.

Originality/value

Finally through numerical simulation, it is found that the equilibrium profits of the supplier, the manufacturer and the supply chain increase monotonously in relation to the unit government subsidy, while the optimal profit of the assembler in relation to the unit government subsidy tends to decrease first and then increase.

Abstract

Purpose

The purpose of this article is based on the unit patent license fee model in the closed-loop supply chain.

Design/methodology/approach

This paper analyzes the impact of the bundling strategy of the retailer selling new products and remanufactured products on the closed-loop supply chain under the condition that the original manufacturer produces new products and the remanufacturer produces remanufacturing products.

Findings

The results show that alternative products can be bundled, and in many cases, the bundling of remanufactured products and new products is better than selling alone.

Originality/value

If the retailer chooses bundling, for the remanufacturer, when certain conditions are met, the benefits of bundling are greater than the separate sales at that time; for the original manufacturer, when the recycling price sensitivity coefficient is high, the bundling is better than separate sales.

Abstract

Purpose

In China the maturity of the industrial development has the demonstration and reference implications for how to achieve enterprises competitiveness among the developing industries in a country. With the development of globalization, how to improve the enterprises competitiveness has became a serious problem to be solved for Chinese enterprises. The management innovation is reasonable and appropriate to solve this problem. Compared with the independent innovation, adoptive management innovation has become the main way for enterprises to fulfill the management innovation and change the management styles under the open economy condition. The research strives to reveal the “black box” in the management innovation adoptive process and give an answer to a series of questions, such as “what is the role of entrepreneurs in management innovation adoptive process?”

Design/methodology/approach

Exploratory case study approach is taken to find the entrepreneurs' role in management innovation adoptive process of Chinese traditional industry.

Findings

This paper constructs the adoptive management innovation model from three dimensions, using exploratory case technique, which explores the key factors and mechanism of realizing management innovation adoption. Through the exploratory case analysis to verify the viewpoint which is proposed by the model: entrepreneurs played a leading role in the adoptive management innovation of non‐procedural process, and the role is the result of the mixed function of the external and internal environment. Entrepreneurs analyze and explore the new problems and opportunities, and their own experience and ability determine the cognition and explore degree towards these problems directly; entrepreneurs' integration ability of resources can be approved and accepted after the new practice has been proposed and become mature. Entrepreneur long‐term shaping on organizational resources determines whether the management innovations introduction would be really integrated into enterprise management system. The entrepreneur's typical behavior on “integration, learning and shaping” is the foundation and guarantee of adoptive management innovation, which have connective effect on adjacent stages.

Originality/value

The article describes Haier BPR process of adoptive management innovation and the adoptive management innovation mode, and analyzes the effect of entrepreneurs' role on adoptive management innovation of China's color TV industry. The Chinese color TV industry as the maturity industry has the demonstration and reference implications for how to achieve enterprises competitiveness in Chinese developing industries.

Abstract

Purpose

The color TV industry in China has become a mature industry. Its development demonstrates and provides reference implications for how developing industries within a country can achieve a technological leap. This paper aims to address this issue.

Design/methodology/approach

An exploratory case study approach is taken to find the key factors in the technological catch‐up of China's traditional industry.

Findings

In the study it is found that China's color TV industry, as a mature traditional industry, has four‐dimensional key factors affecting the catch‐up of technology in the flat‐panel stage: market; merger and acquisition; international cooperation innovation for patent; and the roles of internal reform. “Market” is the window of opportunity and challenge; “merger and acquisition” is the key factor for making the patent convert from external mode to internal mode by deviant‐track. The “international cooperation innovation for patent” is also a key factor to ensure achievement of technology catch‐up and sustainable technological innovation. The role of internal reform promoter is the key factor in the technological catch‐up process in which taking entrepreneur as the core.

Originality/value

Abstract

Purpose

The privacy calculus based on a single stakeholder failed to explain users' co-owned information disclosure owing to the uniqueness of co-owned information. Drawing on collective privacy calculus theory and impression management theory, this study attempts to explore the co-owned information disclosure of social network platform users from a collective perspective rather than an individual perspective.

Design/methodology/approach

Drawing on collective privacy calculus theory and impression management theory, this study explores the co-owned information disclosure of social network platform users from a collective perspective rather than an individual perspective based on a survey of 740 respondents.

Findings

This study finds that self-presentation and others presentation directly positively affect users' co-owned information disclosure. Also, self-presentation, others presentation and relationship presentation indirectly positively affect users' co-owned information disclosure via relationship support. Furthermore, personal privacy concern, others' privacy concern and relationship privacy concern indirectly negatively affect users' co-owned information disclosure via relationship risk.

Originality/value

The findings develop the theory of collective privacy calculus and impression management, which offer insights into the design of the collective privacy protection function of social network platform service providers.

Abstract

Purpose

The importance of psychological capital (PsyCap) and perceived organizational support (POS) have been identified over the years, however, the underlying relationship of both constructs with different employee outcomes is still a subject of research. The purpose of this study is to investigate whether POS helps in mediating the effect of PsyCap on employee engagement (EE).

Design/methodology/approach

In total, 420 samples (middle-level information technology (IT) professionals) were collected from different IT industry located in India by using online survey questionnaires. The collected data were further analyzed using regression analysis, factor analysis, structural equation modeling, reliability and validity analysis, mediation analysis and model fit indices analysis.

Findings

The results of the present study confirmed the full mediating effect of POS on the PsyCap-EE relationship and demonstrated that employees with a higher level of PsyCap, contribute more positively to the POS level which further enhances the employee’s level of engagement at the workplace.

Research limitations/implications

The samples collected for the current study included only middle-level IT professionals of the IT industry in India; therefore, the present study results have limited general applicability. The results and findings of the current study are only on the basis of inferential statistical analysis, and descriptive analysis was not performed on the collected data. Further, the study does not investigate the influence of time.

Practical implications

This study would assist practitioners of human resources in organizational development by enhancing the employee’s positive attitude and commitment toward their study. Further, EE can also be improved by enhancing the levels of POS and PsyCap of employees, which is in line with the findings of the current study.

Originality/value

The current study examines the mediating effect of POS on psychological capital and EE the relationship for the first time.

Abstract

Purpose

Sharing co-owned information on social network platforms has become a common and inevitable phenomenon. However, due to the uniqueness of co-owned information, the privacy calculus theory based on a single information owner cannot explain co-owned information disclosure. Therefore, this study tries to investigate the underlying mechanism of users’ co-owned information disclosure from a collective privacy calculus perspective.

Design/methodology/approach

Through a survey of 740 participants, covariance-based structural equation modeling (CB-SEM) was used to verify the proposed model and hypotheses.

Findings

The results show that personal benefit, others’ benefit and relationship benefit promote users’ co-owned information disclosure by positively affecting personal distributive fairness and others’ distributive fairness perception. Meanwhile, personal privacy risk and others’ privacy risk prevent users’ co-owned information disclosure by negatively affecting personal distributive fairness and others’ distributive fairness perception. Besides, others’ information ownership perception enhances the positive effect of others’ distributive fairness perception on co-owned information disclosure intention. Furthermore, others’ information ownership strengthens the mediating role of others’ distributive fairness.

Research limitations/implications

The findings of this study enrich the research scope of information disclosure and privacy calculus theory and help social network platform developers design collective privacy protection functions.

Originality/value

This study develops a collective privacy calculus model to understand users’ co-owned information disclosure on social network platforms, confirming the mediating role of collective distributive fairness and the moderating role of others’ information ownership perception in the process of collective privacy calculus.
