Abstract

Purpose

This paper proposes a design of an efficient and automated experimental platform for frequency modulated continuous wave (FMCW) radars. The platform can quickly flexibly generate the waveform that meets measurement requirements and significantly improve experimental efficiency.

Design/methodology/approach

This platform not only includes radio frequency devices but also integrates a programmable transmitter based on field programmable gate array. By configuring the waveform data, the experimental platform can generate waveforms with adjustable parameters and realize automatic emission, reception and processing of signals. Different from traditional fast Fourier transform, this paper uses a discrete-time Fourier transform to process low-frequency signals to get more accurate results.

Findings

The authors demonstrate the effectiveness of the platform through a single-path cable experiment, an indoor ranging experiment by using different modulating waveforms and a speed measurement experiment. With complete functions and strong flexibility, the platform can operate effectively in various conditions and greatly improve the efficiency of research and study.

Practical implications

The platform can accelerate the research studies and applications of FMCW radars in the fields of automatic drive, through-wall detection and health-care applications.

Originality/value

Cost and functionality are taken into account in the platform, which can significantly improve the efficiency of research. The proposed signal processing method improves the accuracy while its computation complexity does not increase significantly.

Abstract

The assumption that the family migrates as a unit downplays migrants’ circularity. This chapter focuses on China's rural–urban labor migrants that travel back and forth between the sites of work and home community and between places of work. I argue that migrants and their households pursue work flexibility in order to obtain the best of the urban and rural worlds, by gaining earnings from urban work and at the same time maintaining social and economic security in the countryside. Work flexibility demands flexibility in household organization, in the form of division of labor and collaboration between genders, generations, and households. Based on a study in Sichuan, I examine household biographies and narratives to identify migrants’ work and household strategies.

Migrants change jobs frequently, switch from one type of work to another and one location to another readily, and often return to the home village for months or even years before pursuing migrant work again. Not only are migrants ready to split the household between the city and the countryside, but also they frequently change from one form of division of labor to another. The inside–outside model, where the wife stays in the village and the husband does migrant work, used to be the dominant arrangement. Over time, the outside–outside model, where both the husband and wife migrate to work and leave behind other family members, is increasingly popular. This is facilitated by intergenerational and interhousehold division of labor in the form of assistance by the extended family. Intergenerational division of labor takes place when the second generation is replacing the parents in migrant work. This research's findings support the notion that rural–urban migrants are fast becoming a hybrid segment of Chinese society, playing dual roles of farmers and urban workers and straddling the peasant and urban worlds.

This paper aims to study the influence of NaNO2 on the chemical composition of passivation film.

Abstract

Purpose

This paper aims to study the influence of NaNO2 on the chemical composition of passivation film.

Design/methodology/approach

X-ray photoelectron spectroscopy and X-ray diffraction were selected to determine the composition of passivation film of steel bars in mortar. The specimens were exposed to the chloride solution, carbonation environment and the coupling effects of chloride solution and carbonation. The chemical composition and micro structures at 0 and 5 nm from the outer surface of the passivation film of steel bars were analyzed.

Findings

Results showed that the nitrite inhibitor improved the forming rate of the passivation film and increased the mass ratio of Fe3O4 to FeOOH on the surface of steel bars. The component of Fe3O4 at 5 nm of the steel passivation film was more than that at 0 nm. Sodium ferrite in the pore solution was easily hydrolyzed and then FeOOH was formed. Therefore, due to the nitrite inhibitor, a “double layer structure” of the passivation film was formed to prevent steels bars from corrosion.

Originality/value

This is original work and may help the researchers further understand the mechanism of rust resistance by nitrite inhibitor.

Abstract

Purpose

This study aims to examine the role of women’s career expectations (CEs) in changes in their career advancement (CA) and to determine whether these changes were because of socio-demographic factors.

Design/methodology/approach

Multiple linear regression was used to measure the relationship between women’s CEs and CA, as well as the influences that socio-demographic factors (e.g. education) have on that relationship.

Findings

Results indicated that CEs had two dimensions (i.e. career rewards and career development) and that career reward expectations had a significantly higher effect on CA than career development expectations. Furthermore, women were very likely to set higher CEs and stronger desires for CA as they became older. Results also showed that education, working years and position level were significantly related to women’s CA.

Practical implications

This study provides new insight into which aspects of women’s CA can be boosted by CEs and how these aspects may be affected by socio-demographic factors. This study can help hotels design better career management strategies to achieve the desired results. The study also provides guidance for women’s career management activities.

Originality/value

This study considers women’s CEs in hotels. The results revealed two dimensions (i.e. career rewards and career development) of CEs and uncovered the influences of socio-demographic factors on women’s CA, for example, age, education, working years and position level.

研究目的

Abstract

Firm internationalization or the degree of internationalization (DOI) has both been viewed as a critical dimension of company strategy and linked with enhanced firm performance. This research reports a theoretical postulation based on a conceptual synthesis and an empirical assessment, of this relationship among Chinese firms. Based on the economies of scale, market seeking, risk reduction and experiential learning benefits and possible threshold effects due to learning and accumulation, it is hypothesized that there is a curvilinear relationship between DOI and firm performance and furthermore firms in open or more marketized regions of China will benefit more from their internationalization efforts because of the supportive institutional environment. Multiple regression models employing a large data set of Chinese firms provided supportive empirical evidence. Theoretical and practical implications and research directions are considered.

Abstract

Purpose

Strategic change is critical for firms suffering greater environmental uncertainty, but how can firms change their strategies quickly? The purpose of this paper is to examine the impact of entrepreneurial orientation (EO) on the speed of strategic change (SSC) together with the moderating effect of strategic flexibility (composed of resource flexibility (RF) and coordination flexibility (CF)).

Design/methodology/approach

A survey instrument of 351 Chinese firms obtained through the face‐to‐face interview method is used to empirically test the hypotheses.

Findings

This study finds that EO has a positive impact on the SSC. In addition, the moderating effect of RF on the relationship between EO and the SSC is inverse U‐shaped, while that of CF is positive. The findings indicate that both EO and strategic flexibility are important antecedents of the SSC.

Originality/value

This study adds an in‐depth understanding on the roles of EO and strategic flexibility as the antecedents of the SSC.

Abstract

This study explores the role of procedural and distributive justice in influencing supervisory trust, job satisfaction, and organizational commitment. Past work in U.S. settings has shown the differential effects of procedural and distributive justice on job attitudes while other work supports the relationship between both procedural and distributive justice with trust. This study attempts to replicate the US findings and extend them to samples from India, Germany, and China (Hong Kong). A theoretical model was tested via structural equation analysis. Organizational justice was found to be an important predictor of trust in all the samples, indicating the importance of these concepts in organizational life in different cultures. The implications of these results for future research are discussed.

Abstract

Purpose

This paper aims to explore the influence of founder shareholders’ resources on the allocation of control rights from the perspective of incomplete contract theory and resource-based theory.

Design/methodology/approach

This paper analyzes newspaper materials with NVivo11on a case of battle for corporate control in Chinese top-listed company-Vanke Group.

Findings

The research shows that human capital is the key resource and the holding proportion of financial resources directly affects the allocation of control rights. At the same time, social capital is unstable and easily broken. At last, institutional environment also affects the degree between the relationship of founder shareholders’ resources and the allocation of control rights. The influence of founder-shareholder resources on the allocation of control rights follows the path of “crisis – founder-shareholder’s resources – founder’s ability - allocation of control rights.”

Research limitations/implications

This study only selects the financial capital, human capital and social capital of Shi Wang, the founder of Vanke, as the analysis object. The study can expand the types of founder shareholder resources to verify and enrich the conclusions.

Originality/value

The current theoretical research in the literature focuses on the necessity of equity and shareholder’s resources versus the control rights. Some key factors and mechanism on the relationship have not been fully clarified. The results of this paper not only extend the combination research of social network and corporate governance, but also provide enterprise founders with references for making reasonable decisions during control battle.
