Abstract

Purpose

The purpose of this paper is to propose a three-dimensional (3D) assembly model retrieval method based on assembling semantic information to address semantic mismatches, poor accuracy and low efficiency in existing 3D assembly model retrieval methods.

Design/methodology/approach

The paper proposes an assembly model retrieval method. First, assembly information retrieval is performed, and 3D models that conform to the design intention of the assembly are found by retrieving the code. On this basis, because there are conjugate subgraphs between attributed adjacency graphs (AAG) that have an assembly relationship, the assembly model geometric retrieval is translated into a problem of finding AAGs with a conjugate subgraph. Finally, the frequent subgraph mining method is used to retrieve AAGs with conjugate subgraphs.

Findings

The method improved the efficiency and accuracy of assembly model retrieval.

Practical implications

The examples illustrate the specific retrieval process and verify the feasibility and reasonability of the assembly model retrieval method in practical applications.

Originality/value

The assembly model retrieval method in the paper is an original method. Compared with other methods, good results were obtained.

Abstract

Purpose

The purpose of this study is to present the state of the art for fiber Bragg grating (FBG) acceleration sensing technologies from two aspects: the principle of the measurement dimension and the principle of the sensing configuration. Some commercial sensors have also been introduced and future work in this field has also been discussed. This paper could provide an important reference for the research community.

Design/methodology/approach

This review is to present the state of the art for FBG acceleration sensing technologies from two aspects: the principle of the measurement dimension (one-dimension and multi-dimension) and the principle of the sensing configuration (beam type, radial vibration type, axial vibration type and other composite structures).

Findings

The current research on developing FBG acceleration sensors is mainly focused on the sensing method, the construction and design of the elastic structure and the design of a new information detection method. This paper hypothesizes that in the future, the following research trends will be strengthened: common single-mode fiber grating of the low cost and high utilization rate; high sensitivity and strength special fiber grating; multi-core fiber grating for measuring single-parameter multi-dimensional information or multi-parameter information; demodulating equipment of low cost, small volume and high sampling frequency.

Originality/value

The principle of the measurement dimension and principle of the sensing configuration for FBG acceleration sensors have been introduced, which could provide an important reference for the research community.

Abstract

Purpose

Journalism students, a special user group with the dual perspective of both social media general users and online journalists, and their trust in rumours is a valued but understudied topic in relation to preparing rational information users and professionals for rumour control. To reveal these trust mechanisms, this paper aims to identify salient psychological and behavioural factors related to journalism students’ different levels of trust.

Design/methodology/approach

Using structural equation modelling to analyse the survey data of 234 journalism students, this paper tested a theoretical model that considers self-efficacy and the expressive and consumptive use of social media rumours as the antecedents and consequences of trust belief and trust action, respectively.

Findings

Self-efficacy has a positive effect on trust belief but a negative effect on trust action. Trust belief positively affects expressive use of rumours, whereas trust action negatively affects consumptive use.

Practical implications

This study contributes to the cultivation of future online news gatekeepers.

Originality/value

This paper distinguishes journalism students’ trust mechanisms from those of general users and online journalists. The integration of dual process theories provides insights into trust-building processes related to rumours and advances the understanding of the anchoring and adjustment effects of self-efficacy on trust.

Abstract

Purpose

The purpose of this paper is to explore the potential causes of the reduction of cotton cultivation in Shandong Province of China from the perspective of smallholders and notably examine the role of off-farm employment.

Design/methodology/approach

This paper extends an integrated behavioral model to analyze the relationship between off-farm employment and cotton cultivation by taking into account farmers’ risk attitudes. A household survey data of 144 Bt cotton farmers in six villages in Linqing County, Shandong Province conducted in 2012 and 2013 is used. A simultaneous equations model is established and further estimated by using three-stage least squares method.

Findings

Although the introduction of Bt cotton has promoted the increase in cotton acreage in China from 1999 to 2007, the planting area of cotton has been decreasing since 2007. The results show the significant correlations among risk attitude, off-farm employment, and cotton cultivation. The planting area of cotton is positively correlated with farmers’ willingness to take risk but negatively associated with off-farm employment of family members. The findings imply that the rapid emergence of off-farm labor markets is a major reason for the reduction of cotton acreage in Shandong Province. In the context of the more opportunities of off-farm employment in China, cotton acreage is expected to decrease further.

Originality/value

The findings provide a reasonable explanation for the reduction of cotton cultivation in Shandong. This analysis contributes to a better understanding of the relationships among individual risk attitude, off-farm employment, and agricultural behavior, thereby adding to the literature about the application of the integrated behavioral model.

Abstract

Purpose

The purpose of this paper is to differentiate between two types of job resources (i.e. task resources and social resources) and extends the job demands-resources (JD-R) model with a typically Chinese form of social exchange – guanxi exchange – to increase its applicability in the Chinese context.

Design/methodology/approach

Multigroup structural equation analysis was used to test the hypotheses in two cross-sectional Chinese samples of 463 police officers and 261 nurses.

Findings

Results supported the distinction between social resources and task resources. Social resources were positively related to engagement and organizational commitment (for police officers), task resources were positively related to engagement (for both nurses and police officers), organizational commitment (for police officers), and negatively to burnout (for police officers). Guanxi exchange with supervisors was positively associated with social resources (for both nurses and police officers), task resources (for nurses), and organizational commitment (for police officers). Moreover, guanxi exchange was positively related with work engagement in both nurses and police officers. Unexpectedly, guanxi exchange was positively related with burnout in police officers.

Research limitations/implications

Due to its cross-sectional design, longitudinal replication of the findings is desirable in order to establish causality.

Practical implications

The effects of informal interpersonal relations (i.e. guanxi exchange) on employees’ well-being and organizational commitment should be acknowledged, especially when developing strategies to reduce burnout and increase work engagement.

Originality/value

For the first time, task resources and social resources are distinguished and a Chinese traditional concept (guanxi exchange) is integrated into the JD-R model.

Abstract

Purpose

The National People’s Congress (NPC) of People’s Republic of China, the highest organ of state power, is popularly seen as a rubber-stamp entity. However, it has been substantially evolving its roles to accommodate the governance discourses within China’s political system over the decades. This study aims to explore the changes of governance discourse of the NPC within China’s political system through which to offer a thorough understanding of the NPC’s evolving substantial role in current China.

Design/methodology/approach

This study deploys a historical approach to explore the changes of governance discourse of the NPC that has seen a growing importance in China’s political agenda, as argued by this study.

Findings

The authors find that the NPC has been substantially evolving its role within China’s political system in which the Chinese Communist Party has created different governance discourses. Besides, the NPC and its Standing Committee have asserted its authority as a substantial actor within China’s political system. The NPC is no longer functioned as a rubber-stamp institution, though it is still popularized as a rubber stamp by many scholars.

Research limitations/implications

This study is a historical elaboration on the development of NPC under three governance discourses. It might be, to some extent, relatively descriptive in nature.

Originality/value

This study, therefore, sheds some light on a revisit on the governance discourses in current China.

Abstract

Purpose

The purpose of this paper is to study the impact of job insecurity (past job downsizing and anticipated job downsizing) and current remuneration – via wellbeing (burnout and work engagement) – on organizational outcomes (organization commitment and low turnover intention) of Chinese family‐owned business.

Design/methodology/approach

The Job Demands‐Resources (JD‐R) model is used as a conceptual framework and data from 585 workers of three Chinese family‐style factories were analyzed using structural equation modeling.

Findings

Results confirm the hypothesized model indicating that in accordance with the JD‐R model: job resources (i.e. job downsizing and current remuneration) are associated with organizational outcomes through wellbeing (burnout and work engagement) and; anticipated job downsizing fully mediates the relation of past job downsizing with wellbeing.

Originality/value

The current study examined the effects of job insecurity (i.e. downsizing) and current remuneration on organization outcomes of workers in Chinese family‐owned business using a questionnaire survey. To date, studies using the JD‐R model focused on other work characteristics but overlooked the potential role of job insecurity and current remuneration. The study demonstrated the importance of anticipated and past downsizing and current remuneration for employee wellbeing and organization outcomes.

Abstract

Purpose

This study aims to investigate the relation between job demands and job resources on the one hand and employee well‐being (burnout and work engagement) on the other. It was assumed that this relation is mediated by an equity‐based cognitive evaluation process.

Design/methodology/approach

This mediation hypothesis was tested using the Job‐Demands Resources model in two Chinese samples of blue collar workers (n=625) and nurses (n=1,381).

Findings

As expected, structural equation analysis revealed that equity mediated the relation of job demands and job resources with burnout and work engagement among nurses. However, mediation was only partly confirmed among blue collar workers. In addition, and as expected, among nurses equity was non‐linearly related with burnout.

Research limitations/implications

The cross‐sectional design of the present study precludes causal conclusions.

Originality/value

The study extended the JD‐R model with an equity‐based cognitive evaluation process.

Abstract

Purpose

The purpose of this paper is to establish an adaptive assembly, to realize the adaptive changing of the models and to improve the flexibility and reliability of assembly change. For a three-dimensional (3D) computer-aided design (CAD) assembly in a changing process, there are two practical problems. One is delivering parameters’ information not smoothly. The other one is to easily destroy an assembly structure.

Design/methodology/approach

The paper establishes associated parameters design structure matrix of related parts, and predicts possible propagation paths of the parameters. Based on the predicted path, structured storage is made for the affected parameters, tolerance range and the calculation relations. The study combines structured path information and all constrained assemblies to build the adaptive assembly, proposes an adaptive change algorithm for assembly changing and discusses the extendibility of the adaptive assembly.

Findings

The approach would improve the flexibility and reliability of assembly change and be applied to different CAD platform.

Practical implications

The examples illustrate the construction and adaptive behavior of the assembly and verify the feasibility and reasonability of the adaptive assembly in practical application.

Originality/value

The adaptive assembly model proposed in the paper is an original method to assembly change. And compared with other methods, good results have been obtained.

Abstract

Purpose

The purpose of this paper is to assess whether China’s public sector can continue to generate advanced genetically modified (GM) technologies that will be competitive in the market.

Design/methodology/approach

The authors investigated all the research teams that have been conducting research projects under the variety development special program. The data collected include detail information on research capacity, research areas, performance, and process of their research projects. Based on the survey data, the authors assessed the innovations and progress of the variety development special program.

Findings

Unlike other countries, most GM products in China are developed by public research institutes. There is rising concern on the ability of China’s public sector to continuously generate indigenous GM technology that can compete with multinational companies. The study surveyed 197 research institutes and 487 research teams and found that the GM program in China lacks coordination: researchers do not want to share their research materials with others. Due to the lack of coordination, most of the hundreds of research teams often worked independently in the year 2008-2010. Moreover, the authors found the lack of coordination may be due to the reason that the interests of researchers are not well protected. This paper also provided the recent progress and policy changes of GM program in China, and it found that the efficiency in the later three years improved a lot. In order to establish a competitive national public GM research system, China should continuously consolidate and integrate the upstream, midstream, and downstream activities of the whole GM innovation process. China’s public sector may also need to work more closely with both the domestic and international private sectors.

Originality/value

This paper is a comprehensive analysis on the development of transgenic technology in China. The results of this paper can provide evidence for the dynamic adjustment of the policies in the variety development special program and can also provide reference for the future assessment of the variety development special program.
