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.

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

基于对酒店业两个变量(即职业期望和职业晋升)的理解, 本研究旨在考察职业期望在妇女职业晋升变化中的作用, 并确定这些变化是否由社会人口特征因素引起。

设计/方法/途径

采用问卷调查的方式收集数据。采用多元线性回归来衡量女性职业期望和职业晋升之间的关系, 以及社会人口特征因素(如教育)对这种关系的影响。

研究结果

结果表明, 职业期望有两个维度(即职业奖励和职业发展), 职业奖励期望对职业晋升的影响明显高于职业发展期望。此外, 随着年龄的增长, 女性倾向于有更高的职业期望和更强烈的职业晋升愿望。结果还显示, 受教育程度、工作年限、职位级别与女性的职业晋升显著相关。

实践意义

这项研究为女性职业期望在哪些方面可以促进职业发展以及社会人口特征因素如何影响这些方面受到的提供了新的见解。这项研究可以帮助酒店设计更好的职业管理策略, 以达到预期效果。本研究也为女性的职业管理活动提供了指导。

Abstract

Purpose

This paper aims to explore students’ work-integrated learning experience. Particularly, students’ application of knowledge and improvement of multiple skills in work-integrated learning, their influence on positive industry image change due to the COVID-19 pandemic, and students’ desired career prospect were explored.

Design/methodology/approach

A questionnaire survey with valid responses from 168 undergraduate students in hospitality and tourism management was conducted in four colleges/universities in Guangdong, China in 2021. PLS-SEM method was used to analyze the data.

Findings

It was found that students’ multiple skills had improved through application of knowledge in work-integrated learning. Skill improvement helped form positive industry image change and shape future career prospect. However, such positive industry image change did not impact students’ career prospect directly.

Originality/value

Today, work-integrated learning has become one of the most valuable opportunities for students in hospitality and tourism management to gain industry experience. However, recent literature has largely examined the negative impacts of COVID-19, whereas few studies have examined the positive aspects of work-integrated learning.

Abstract

Purpose

With an explosion of datasets available on the Web, dataset search has gained attention as an emerging research domain. Understanding users' dataset behaviour is imperative for providing effective data discovery services. In this paper, the authors present a study on users' dataset search behaviour through the analysis of search logs from a research data discovery portal.

Design/methodology/approach

Using query and session based features, the authors apply cluster analysis to discover distinct user profiles with different search behaviours. One particular behavioural construct of our interest is users' expertise that the authors generate via computing semantic similarity between users' search queries and the title of metadata records in the displayed search results.

Findings

The findings revealed that there are six distinct classes of user behaviours for dataset search, namely; Expert Research, Expert Search, Expert Explore, Novice Research, Novice Search and Novice Explore.

Research limitations/implications

The user profiles are derived based on analysis of the search log of the research data catalogue in this study. Further research is needed to generalise the user profiles to other dataset search settings. Future research can take on a confirmatory approach to verify these user groups and establish a deeper understanding of their information needs.

Practical implications

The findings in this paper have implications for designing search systems that tailor search results matching the diverse information needs of different user groups.

Originality/value

We propose for the first time a taxonomy of users for dataset search based on their domain expertise and search behaviour.

Abstract

Purpose

The purpose of this study is to propose a comprehensive efficiency evaluation approach to measure the efficiency of the retailers and to determine the relative importance of a wide variety of apparel retail-specific factors that support efficiency.

Design/methodology/approach

The first stage of the proposed approach is the measurement of the relative efficiency of the apparel retailers by using data envelopment analysis (DEA) for identifying the best practice frontier and determination of the improvement ratios. The second stage is the prioritization of the factors that are important in the apparel retail efficiency using analytical hierarchy process (AHP).

Findings

The findings of the study revealed that the quantitative criteria to be considered for efficiency through input minimization and output maximization were “number of employees” and “profit before tax,” respectively, however, focusing on output maximization was found to be more critical. In addition, it was seen that the most important qualitative components of efficiency were satisfied customers, qualified staff and branding.

Practical implications

The managerial actors in the apparel retail industry can be alerted for new strategic actions to adopt best practices or take precautions for future inefficiencies with the help of the results obtained. The customized hierarchical structure allows determining the priority areas that need to be focused on for increasing the performance of apparel retailers.

Originality/value

In this study, DEA and AHP were combined to build a comprehensive efficiency evaluation approach in the apparel retail industry for the first time in the literature. Thus, both qualitative and quantitative variables that are important in apparel retail efficiency were put forward and evaluated. The originality of the hierarchical structure in AHP was its customization to the apparel retail industry.

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.
