Abstract

Purpose

This paper aims to propose a methodology to remove inherent implicit creep from the Eurocode 3 material model for steel and to present a creep-free analysis on simply supported steel members.

Design/methodology/approach

Most of the available material models of steel are based on transient coupon tests, which inherently include creep strain associated with particular heating rates and load ratios.

Findings

The creep-free analysis aims to reveal the influence of implicit creep by investigating the behaviour of simply supported steel beams and columns exposed to various heating regimes. The paper further evaluates the implicit consideration of creep in the Eurocode 3 steel material model.

Originality/value

A modified Eurocode 3 carbon steel material model for creep-free analysis is proposed for general structural fire engineering analysis.

Abstract

Purpose

Driven by the development in sensing techniques and information and communications technology, and their applications in the manufacturing system, data-driven quality control methods play an essential role in the quality improvement of assembly products. This paper aims to review the development of data-driven modeling methods for process monitoring and fault diagnosis in multi-station assembly systems. Furthermore, the authors discuss the applications of the methods proposed and present suggestions for future studies in data mining for quality control in product assembly.

Design/methodology/approach

This paper provides an outline of data-driven process monitoring and fault diagnosis methods for reduction in variation. The development of statistical process monitoring techniques and diagnosis methods, such as pattern matching, estimation-based analysis and artificial intelligence-based diagnostics, is introduced.

Findings

A classification structure for data-driven process control techniques and the limitations of their applications in multi-station assembly processes are discussed. From the perspective of the engineering requirements of real, dynamic, nonlinear and uncertain assembly systems, future trends in sensing system location, data mining and data fusion techniques for variation reduction are suggested.

Originality/value

This paper reveals the development of process monitoring and fault diagnosis techniques, and their applications in variation reduction in multi-station assembly.

Abstract

Purpose

The purpose of this study is to examine the differential association of family supportive supervisor behavior on promotive voice under different gender. Further, while employees’ self-concept factors have received considerable attention in the research on the triggering mechanism of employee voice, the authors’ knowledge about how and when family factors affect employee voice remains underdeveloped.

Design/methodology/approach

According to the resource conservation theory and gender role theory, the authors constructed a research model to investigate the influence and boundary of family supportive supervisor behavior on employee promotive voice and tested their research model using a paired data of 332 married employees and their direct supervisors of enterprises in China.

Findings

The findings suggest that family supportive supervisor behavior has a positive effect on employee promotive voice. Family supportive supervisor behavior can strengthen employee promotive voice by improving work-to-family enrichment and reducing work–family conflict, yet no significant mediation effect was found regarding family-to-work enrichment and conflict. Furthermore, family supportive supervisor behavior is more likely to improve female employee work–family enrichment and assuage male employee work–family conflict and thus enhance employee promotive voice.

Originality/value

This study sheds light on the different influential paths of family supportive supervisor behavior on promotive voice of employees of different genders and provides references for enterprises to motivate employees’ promotive voice.

Abstract

Since China initiated its “go global” policy that promotes its overseas investment, China’s Outward Foreign Direct Investment (OFDI) has increased almost twenty times during the last 10 years, reaching $55.9 billion in 2008. The issue of internationalization of Chinese OFDI has attracted increasing attention of researchers from a business perspective. This article systematically reviews the previous studies on overseas investments by Chinese MNEs and discusses the characteristics of Chinese internationalization behavior at both firm level and country level. The internationalization of Chinese companies cannot be understood as a simple game of “catch up” with established MNEs, and more firm‐level empirical studies should be carried out on how these characteristics influence firms’ strategic decisions.

Abstract

Purpose

Large-scale mobile radars are still erected manually by using lifting equipment, which often fails to meet the requirements on precision, quality and efficiency in the erecting process. This paper aims to introduce techniques for automatic assembly of large mobile radar antenna.

Design/methodology/approach

A large-scale metrology system for accurate identification of the positions and orientation of the radar antenna components is presented. A novel three-degree-of-freedom parallel mechanism is designed to realize orientation adjustment of three axes synchronous, and, thus guarantees the efficiency and accuracy of positioning process.

Findings

The system described in this paper is practicable in outdoor environment and provides a holistic solution that gives full consideration of the operation conditions and the environmental influences. In performance evaluation tests, the measured absolute accuracy is less than ±1 mm and repeatability is less than ±0.5 mm in the positioning task for 10 × 3 m large antenna.

Originality/value

This paper presents a new concept of an automatic assembly technology for the large radar antenna application.

Abstract

Purpose

The purpose of this paper is to explore the status quo and the strength difference of the climate for innovation among firms with different ownership structures, in different industrial sectors, and in different developmental stages in China.

Design/methodology/approach

The study used a survey method to explore the differences of innovative climate among firms with different ownership structures, difference in developmental stage and in different industries. It collected 624 data from 52 companies by purposive and snowball sampling methods. A structural equation model and ANOVA analysis, along with multiple comparisons, were employed to test the hypothesis.

Findings

First, by factor analysis and structural equation models, the study proved that the organizational innovative climate model in the Chinese organizational context is a seven dimension structural model, which includes such first‐order factors as working environmental support, innovative vision, leader support, team support, resources supply, learning and growth and knowledge and skills. Second, the results indicate firms in different developmental stages have significant differences in almost all dimensions of climate for innovation. Third, there is no significant difference in innovative climate among firms in different industrial sectors, but further analysis of multiple comparisons shows that there are relative strengths and weaknesses in specific dimensions of innovative climate among such firms. Last, the results suggest that there are significant differences among most dimensions of innovative climate in firms with different ownership structures in China. In assessing employees' experience over seven dimensions of climate, the results demonstrate that respondents vary their answers in the direction of theoretical hypotheses, which validated the relative assumptions.

Originality/value

The research is important because it shows that innovative climate strength may discriminate among different work contexts experienced by employees, which would help deepen our understanding of the present condition of innovative climate in China.

Abstract

Purpose

As more and more people are beginning to take virtual communities (VC) as effective communication channels and the main places to get information and knowledge, understanding the factors that can support or hinder one’s knowledge sharing seems important for the management of VCs. The purpose of this paper is to explore the antecedents that influence people’s knowledge sharing in VCs, and to explore influence mechanism and the boundary condition of how the antecedent affect people’s knowledge sharing in VCs.

Design/methodology/approach

The authors conducted empirical research to test our hypotheses. The authors designed a questionnaire based on previous research and collected the questionnaires from seven VCs in China, including two specific topic-based forums in Baidu Tieba which is the largest Chinese online communication platform, three in traditional university bulletin board system (BBS) forums and another two based on instant messaging service. The final sample the authors got included 96 individuals. Then the authors used the hierarchical linear modeling (HLM) technique to analysis the data.

Findings

The results suggest that community member’s attachment can be a strong indicator of his/her knowledge-sharing intention which will possibly lead to knowledge-sharing behavior. However, this effect can be contingent on individual centrality and community member fluctuations. In a stable community, those who are in the peripheral position are more likely to transfer their attachment into knowledge sharing because they have the intention to move into central positions and knowledge sharing can help them gain status. While in an unstable environment, it does not make any difference between people in different position in the social network.

Originality/value

First, this paper reveals member’s attachment as the antecedent of people’s knowledge sharing in VCs. Second, this paper adopts a network perspective to construct the research model. And the basic point made is that knowledge sharing can be seen as a channel to attain status and centrality in a community. Thus, people who are in periphery positions are more likely to transfer their community attachment into knowledge-sharing intention. Third, this paper emphasizes the dynamic characteristic of members in VCs and proves the moderation effect of community member fluctuations.

Abstract

Purpose

The purpose of this paper is to estimate the real urbanization level in China so as to provide a measurement that can be compared with the international level.

Design/methodology/approach

Taking into consideration 300m residents living in the administrative towns (300m residents here are referred to the population in administrative towns, including those in all counties), the gap between the urbanization rate of China and that of the world average becomes much wider.

Findings

China, however, implements the administrative system of government at the central, provincial, municipal, county and township levels. By city, it means the jurisdiction at and above the level of county, which includes the municipality directly under the central government, prefecture-level municipal and county. By town, it means the jurisdiction below the level of county (including the Chengguan Town, or capital town, where the county government is located) and exclusive of rural townships.

Originality/value

China has witnessed rapid development for 40 years since the reform and opening up in 1978. Nowadays, China has already stepped into the period of post-industrialization, with its urbanization rate (UR) of permanent population reaching 58.58 percent. However, on the basis of registered population, the UR is 43.37 percent, which is not only far below the average level of 81.3 percent in high-income countries, but also lower than the average of 65.8 percent in upper middle-income countries which are comparable to China in terms of per capita income. (The classification of state income level is based on the data of national income per capita and division standards in 2016 from the World Bank, in which annual revenue per capita in high-income countries reaches over US$12,736 and that in upper middle-income countries between US$4,126 and US$12,735.)

Abstract

Purpose

Agricultural workers represent an important part of the population exposed to high heat-related health and productivity risks. This study aims to estimate the heat-related productivity loss (PL) for moderate work activities in sun and shady areas and evaluating the economic cost locally in an Italian farm and generally in the whole province of Florence. Benefits deriving by working in the shade or work-time shifting were provided. Comparisons between PL estimated in Mediterranean (Florence, Italy) and subtropical (Guangzhou, China) areas were also carried out.

Design/methodology/approach

Meteorological data were collected during summers 2017–2018 through a station installed in a farm in the province of Florence and by two World Meteorological Organization (WMO)‐certified meteorological stations located at the Florence and Guangzhou airports. These data were used to calculate the wet-bulb globe temperature and to estimate the hourly PL and the economic cost during the typical working time (from 8 a.m. to 5 p.m.) and by advancing of 1 h and 2 h the working time. Significant differences were calculated through nonparametric tests.

Findings

The hourly PL and the related economic cost significantly decreased (p < 0.05) by working in the shade and by work-time shifting. Higher PL values were observed in Guangzhou than in Florence. The decrease of PL observed by work-time shifting was greater in Florence than in Guangzhou.

Originality/value

Useful information to plan suitable heat-related prevention strategies to counteract the effects of heat in the workplace are provided. These findings are essential to quantify the beneficial effects due to the implementation of specific heat-related adaptation measures to counter the impending effects of climate change.

Abstract

Purpose

To dilute the financial difficulties in agricultural production and operation, the Chinese government has actively explored and developed rural supply chain finance (RSCF) service systems. The purpose of this study is to evaluate and analyze the performance of RSCF systems in China.

Design/methodology/approach

To evaluate the performance of RSCF systems in China, this study proposes a two-stage data envelopment analysis model. Compared with other models, the model proposed in this study considers not only the technical gap between RSCF systems but also the maximization of intermediate output to conform to the practice of RSCF.

Findings

Based on the empirical analysis, this study draws the following four conclusions. First, the overall efficiency of China's RSCF systems is low, and there remains great potential for improvement. Second, the technology gap ratio index score and meta-frontier efficiency of RSCF systems in Central China are the lowest in all regions, indicating that the technical level of RSCF systems in Central China is the lowest. Third, the relationship between rural residents' disposable income and the efficiency of RSCF systems is U-shaped, and the efficiency of RSCF systems in the high-income group is far greater than that of other income groups. Finally, the main reason for the lack of efficiency in RSCF seems to lie in management and technology.

Originality/value

This study divides all RSCF systems into four types according to management potential and technical potential, and recommend corresponding improvement suggestions for different kinds of RSCF systems.
