Abstract

Purpose

Owing to the excellent performance, giant magnetostrictive materials (GMMs) are widely used in many engineering fields. The dynamic Jiles–Atherton (J-A) model, derived from physical mechanism, is often used to describe the hysteresis characteristics of GMM. However, this model, despite cited by many different literature studies, seems not to possess unique expressions, which may cause great trouble to the subsequent application. This paper aims to provide the rational expressions of the dynamic J-A model and propose a numerical computation scheme to obtain the model results with high accuracy and fast speed.

Design/methodology/approach

This paper analyzes different published papers and provides a reasonable form of the dynamic J-A model based on functional properties and physical explanations. Then, a numerical computation scheme, combining the Newton method and the explicit Adams method, is designed to solve the modified model. In addition, the error source and transmission path of the numerical solution are investigated, and the influence of model parameters on the calculation error is explored. Finally, some attempts are made to study the influence of numerical scheme parameters on the accuracy and time of the computation process. Subsequently, an optimization procedure is proposed.

Findings

A rational form of the dynamic J-A model is concluded in this paper. Using the proposed numerical calculation scheme, the maximum calculation error, while computing the modified model, can remain below 2 A/m under different model parameter combinations, and the computation time is always less than 0.5 s. After optimization, the calculation speed can be enhanced with the computation accuracy guaranteed.

Originality/value

To the best of the authors’ knowledge, this paper is the first one trying to provide a rational form of the dynamic J-A model among different citations. No other research studies focus on designing a detailed computation scheme targeting the fast and accurate calculation of this model as well. And the performance of the proposed calculation method is validated in different conditions.

Abstract

Purpose

While marketing analytics can be used to improve organizational decision-making and performance significantly, little research exists to examine how the configurations of multiple conditions affect marketing analytics use. This study draws on configuration theory to investigate marketing analytics use in small and medium-sized enterprises (SMEs).

Design/methodology/approach

This research employs a fuzzy-set qualitative comparative analysis using data collected from a survey of 187 managers in UK SMEs.

Findings

The key findings show that (1) configurations of multiple conditions provide alternative pathways to marketing analytics use, and (2) the configurations for small firms are different from those for medium-sized firms.

Research limitations/implications

The research results are based on several key configurational factors and a single key-informant method to collect subjective data from UK SME managers.

Practical implications

The study helps SMEs to understand that marketing analytics use is influenced by the interaction of multiple conditions, that there are alternative pathways to marketing analytics use, and that SMEs should choose the configuration that fits best with their organizational contexts.

Originality/value

The study contributes to the literature by addressing an important yet underresearched area, i.e. marketing analytics use in SMEs, applying a configurational approach to the research phenomenon. It highlights different pathways to marketing analytics use in SMEs. The findings provide empirical evidence on the possibility and implication of marketing analytics use being asymmetrical and different between small and medium-sized firms.

This study aims to investigate the effect of post-treatment on anti-corrosion performance of Al coating on the surface of Ti-6Al-4V (TC4) fastener.

Abstract

Purpose

This study aims to investigate the effect of post-treatment on anti-corrosion performance of Al coating on the surface of Ti-6Al-4V (TC4) fastener.

Design/methodology/approach

The Al coatings with different layer structures were prepared on TC4 by middle-frequency and direct-current combined magnetron sputtering. The cross-sectional morphology and surface roughness of coatings were characterized by scanning electron microscope and atomic force microscope. The corrosion resistance was evaluated by electrochemical method. The monolayer coating was post-treated by Alodine chemical conversion, Ar+ bombardment and a combination of two methods above.

Findings

The results show that the interfaces in bilayer and trilayer coatings reduce the defects. Ar+ bombardment reduces the corrosion current density, and Alodine chemical conversion leads to a higher pitting corrosion potential. The combined post-treatment has the highest polarization resistance.

Originality/value

The corrosion resistance of the Al coating is enhanced as the layer quantity increases. The combination of two post-treatments, Ar+ bombardment and Alodine chemical conversion, could achieve an overall improvement in corrosion resistance of Al coating.

Abstract

Purpose

This study seeks to understand how accountant stereotypes have been constructed and reconstructed at the macro-national and the structural level in Chinese society.

Design/methodology/approach

This qualitative investigation into China's social construction of accountant stereotypes employs Becker's (1963) labelling theory. Viewing stereotyping as a socially constructed practice, this study draws on a post-positivistic, reflexive epistemology in conducting 28 semi-structured interviews with accountants and related actors.

Findings

Chinese accountant stereotypes are constructed and reconstructed according to the rules created and enforced in different cultural-political periods. The accountant stereotypes constructed during the ancient Confucian period (500 BC – 1948) were replaced during 1949 and 2012 when the political focus shifted towards propagating socialism and later promoting economic growth. They also show how Confucian stereotypes of accountants resurfaced in 2013 but were reconstructed by the central government's cultural confidence policy of propagating Confucianism.

Originality/value

Empirically, prior literature has focused on what the accountant stereotype is and how accountants respond to such stereotypes, but it has neglected the ways in which these accountant stereotypes are politically and culturally constructed, diffused and legitimated. This paper fills in the gap by understanding the social practice of accountant stereotyping in a previously unexplored political-cultural context, namely Chinese society. In theoretical terms, by offering the first use of Becker's (1963) labelling theory in the accounting literature, it furthermore enhances our understanding of how accountants' identities and social standing are shaped by social rules.

The purpose of this paper is to analyze the impact of different information source on consumer attitudes toward genetically modified food.

Abstract

Purpose

The purpose of this paper is to analyze the impact of different information source on consumer attitudes toward genetically modified food.

Design/methodology/approach

The data used in this study are obtained from a large-scale nationwide consumers' survey in urban China conducted by the China Center for Agricultural Policy, Peking University, in 2020. A descriptive analysis between information sources and consumer attitudes toward GM food was conducted. Based on the collected data, an econometric model on the determinants of consumer attitudes was constructed and used for analysis.

Findings

This study shows that the impact of new media is currently no different than that of traditional media, indicating that the media campaign successfully reduced the spread of rumors and misinformation regarding GM food. Moreover, this study also shows that consumers whose main information source regarding GM foods is school hold more positive feelings toward such food.

Originality/value

This study contributes to the existing literature by examining the impact of information source on consumer attitudes toward GM food. To reverse consumers' negative attitudes, China has launched a widespread media campaign since the first decade of the 2000s. Results of this study show that authorities' efforts to manage and surveil new media have yielded the desired outcome.

Abstract

Purpose

This study examines education for sustainability (EfS) within the Chinese context, to specifically enrich the understanding on how EfS is structured and implemented to nurture citizenship in the policy practices of universities in Mainland China and Hong Kong.

Design/methodology/approach

A cross-case analysis is recruited to examine the commonalities and differences between two universities and identify patterns in cultivating sustainability citizenship within higher education institutions (HEIs) in China. Data were collected through reviewing documents, including two universities’ strategic plans, action plans, department meeting memos, program introductions, course outlines and publicity coverage. Observation was also adopted to enrich the data for analysis, covering meetings, speeches by senior management, university events and informal conversations about university operations.

Findings

Citizenship and sustainability in university strategic planning, curriculum and instruction, carriers of EfS institutionalization, and resources and impacts of EfS beyond the institutes were analyzed in a comparative manner, offering valuable insights into how EfS can be institutionalized in different universities based on their unique appeals, existing curriculum and management systems.

Originality/value

By exploring these intra-national distinctions in EfS, the study sheds light on the variation within China's citizenship education, which is traditionally seen as highly unified with limited room for differences. The detailed exploration of university strategies and program/course content enriches the literature of sustainability as an educational phenomenon on an international scale and modernized citizenship education in China.

Abstract

Purpose

This study aims to investigate the antecedents and outcomes of excessive use of personal social media at work. The prevalence of personal social media in the work environment can easily lead to excessive use and negative consequences. Understanding the predictive factors and negative consequences of employees' excessive use of personal social media at work is important to develop their appropriate use of social media and improve their job performance.

Design/methodology/approach

Based on dual-system theory and the person-environment fit model, this study develops a research model to examine the effect of habit and self-regulation on excessive use of personal social media at work and that of the outcomes of excessive use on employee job performance through strain. This study conducts a questionnaire survey on 408 employees to test the research model and hypotheses empirically.

Findings

Results suggest that the imbalance between habit and self-regulation drives excessive personal social media use of employees at work. Furthermore, excessive use of personal social media has a strong impact on employee strain, which can significantly decrease job performance.

Originality/value

First, this study considers excessive use of personal social media at work as a result of two different cognitive systems, that is, an automatic system and a controlled system, thereby extending the dual-system theory to explain excessive use of personal social media in the work context. Second, unlike previous studies that focused on the outcomes or explored the antecedents of excessive social media use at work respectively, the study employs the person-environment fit model and examines the systematic influence of excessive social media use at work from a broad perspective by linking its antecedents and outcomes.

Abstract

Purpose

This study aims to uncover the black box of the influence mechanism between external stakeholder drivers and green public procurement practice, and meanwhile to explore the moderating role of administrative level in this process. Green public procurement (GPP) has been widely implemented. Existing literature has found that external stakeholder drivers can affect public sectors' GPP practice, however, the definition of its connotation is still unclear, and how external stakeholders affect GPP practice has remained a black box.

Design/methodology/approach

After defining the major external stakeholders, this study develops a multiple mediation theoretical model using survey data from 142 Chinese local public sectors. It aims to uncover the black box of the influence mechanism between external stakeholder drivers and GPP practice and meanwhile explore the moderating effect of administrative levels in this process.

Findings

The results show that external stakeholder drivers have a positive relationship with GPP practices. The knowledge of GPP implementation policies and the knowledge of GPP benefits can both mediate this relationship. This study also finds that the administrative level of public sectors can positively moderate the mediating effect produced by the knowledge of GPP implementation policies and negatively moderate the mediation effect produced by the knowledge of GPP benefits.

Social implications

Local governments need to better encourage public sectors to implement GPP. Managers of public sectors need to pay attention to organizational learning to acquire relevant knowledge on GPP.

Originality/value

This study makes a theoretical contribution to a better understanding of the influence mechanism for GPP practice. This study also provides comparisons of GPP implementation policies between China and European Union.
