Abstract

Purpose

Axial field flux-switching permanent magnet machine (AFFSPMM) can be applied in the field of electric and hybrid electric vehicles because of short axial size, large torque density, and high-power density. The purpose of this paper is to improve the reliability of AFFSPMM itself, the design parameters have to be considered for attaining high self-inductances and reduced mutual-inductances.

Design/methodology/approach

The original parameters of E-core AFFSPMM are designed with reference to a 600 W prototype, on the basis of which the 3-D model of the original AFFSPMM is established, and the inductances are calculated by finite element method. The influence of these parameters on the inductances, including combinations of stator and rotor pole numbers, spilt ratio, stator side tooth width, magnet thickness, and rotor pole width etc., are respectively investigated and analyzed under the constant copper loss.

Findings

The relationships of rotor pole numbers and inductances are deduced on the condition of the fixed stator poles. It is found that the rotor pole numbers has significant effects on the ratio of mutual-inductance to self-inductance, and the self-inductance is mainly affected by the rotor pole numbers, the split ratio, the stator tooth width, and the rotor pole width. The asymmetry of back-EMF can be largely reduced by optimizing the rotor tooth width. In this paper, the static characteristics are compared and analyzed for the original and optimal 6/14-pole AFFSPMM. Meanwhile, the open-circuit and short-circuit fault are investigated by transient analysis. The results show that the optimized E-core AFFSPMM has good fault tolerance.

Originality/value

The research of inductance characteristics for E-core AFFSPMM is valuable to design the fault-tolerant machine, by which the cost of control and manufacture can be largely saved.

Abstract

This chapter argues that the National Basketball Association (NBA) and American mainstream sporting media produce and mediate a representation of India as underdeveloped and as an unmodern subject/nation as a way to enter the Indian basketball marketplace. The chapter emphasizes that the NBA produces the attendant discourse of the ‘white saviour’ through a multi-pronged process. The chapter shows how it draws upon the legacies of British colonialism, along with the expansion of US imperialism, to construct India in particular racialised ways as backward, unmodern, and not cosmopolitan. In this respect, Black NBA players’ modes of basketball reach India as part of the racialisation of Indian basketball. Finally, the chapter engages with the larger global circuits of race and racialisation to understand how India is then imagined within the US sporting landscape. This chapter underscores the capitalist desires of the NBA alongside the desires of South Asian Americans for an Indian basketball hero. Both desires, institutional and personal, showcase racialisation at work. The NBA uses the language and performance of Judeo-Christian modernity through NBA players in India to racialise Indians as in need of NBA mentorship and upliftment. On other hand, diasporic Indians in the US dream of an Indian NBA player as a way to unravel, destabilise, and challenge their racialisation as hypo-masculine subjects. These competing forms of racialisation provide important information on the global flows of capital, desire, and sport.

Abstract

In modern China, sports and nationalism always have close connection, and nationalism is the important reason for the promotion of Chinese sports. However, the relationship between Chinese sports and nationalism in globalised China could be much more examined by academics, as well as its influencing factors. This chapter selects the Beijing 2008 Olympic Games as the context and representative three Chinese sports heroes in the period of globalisation to study. The findings show that in some extent, Beijing 2008 Olympic Games and three Chinese sports heroes represent the national image of China in the globalised world, also bearing the burden of washing away historical humiliation and pursuing national glory. Furthermore, it is manifested that China have a complex nationalism in the process of hosting the 2008 Olympic Games. Under the influence of mass media, market economy and sports professionalisation, nationalism still exists in Chinese sports, but people gradually start to reflect on the ‘Juguo Tizhi’, the traditional Chinese sports system and the concept of ‘winning glory for the nation’. The relationship between Chinese nationalism and sports shows the important implications of rapid Chinese sports development.

Abstract

Purpose

Building upon the framework of glocalization, the purpose of this paper is to summarize the development of National Basketball Association (NBA) in Chinese market, explore its successful and unsuccessful places, and propose strategies of glocalization for the NBA as well as other overseas sport leagues.

Design/methodology/approach

The current case study was organized by summarizing the developmental history of NBA in China, analyzing its current promotional practices, investigating into its marketing strategies, and extrapolating practical references for other sport leagues aiming to penetrating into the Chinese marketplace.

Findings

The current case study concluded that when facing the current challenges, the NBA needs to bring authentic American cultural commodities while adding Chinese characteristics to accommodate local fans. Meanwhile, the NBA management needs to continue seeking ways to work out and through the differences in government models and cultural contexts between China and USA. In addition, this study suggested that the research framework of glocalization would be an ever intriguing inquiry needed for other sport organizations or leagues seeking expansion to overseas markets.

Originality/value

A thorough case study with the NBA that has achieved huge successes in Chinese markets will provide valuable implications for sport leagues to broaden their overseas markets.

Abstract

Purpose

Although the literature has somewhat discussed social capital and knowledge sharing, the mediating and moderating mechanisms that influence team workers to move from connecting with one another to building social capital and consequently engaging in knowledge sharing still remain largely understudied. For that reason, this study aims to develop a holistic research framework that links social capital to knowledge sharing with positive affective tone as a mediator and hypercompetition as a moderator.

Design/methodology/approach

Drawing upon the social capital theory and the affective events theory (AET), this study proposes a research framework to assess how social capital factors influence knowledge sharing with the mediation of positive affective tone and the moderation of hypercompetition in high-tech teams. This study obtains survey data based on 330 questionnaires of working professionals from 66 high-tech teams in Taiwan, in which each team comprises four members and their team leader.

Findings

The empirical results of this study show that social interaction, shared vision and trust are positively related to knowledge sharing via the mediation of positive affective tone. Moreover, hypercompetition has positive moderating effects on the relationships between social interaction and positive affective tone as well as between trust and positive affective tone.

Originality/value

This study expands the previous literature to study through what mediating mechanism the effects of different social capital factors on knowledge sharing can be effectively realized and whether there exists any critical moderator that influences these effects.

Abstract

Purpose

The purpose of this paper is to provide the historical background of genealogical records and analyze the value of Chinese genealogical research through the study of names and genealogical resources.

Design/methodology/approach

The paper examines the historical evolution and value of Chinese genealogical records, with the focus on researching the Islamic Chinese names used by the people living in Guilin. The highlight of this paper includes the analysis and evolution of the Islamic Chinese names commonly adopted by the local people in Guilin. It concludes with the recommendations on emphasizing and making the best use of genealogical records to enhance the research value of Chinese overseas studies.

Findings

The paper covers the history of Islam and describes how the religion was introduced into China, as well as Muslims' ethnicity and identity. It also places focus on the importance of building a research collection in Asian history and Chinese genealogy.

Research limitations/implications

This research study has a strong subject focus on Chinese genealogy, Asian history, and Islamic Chinese surnames. It is a narrow field that few researchers have delved into.

Practical implications

The results of this study will assist students, researchers, and the general public in tracing the origin of their surnames and developing their interest in the social and historical value of Chinese local history and genealogies.

Social implications

The study of Chinese surnames is, by itself, a particular field for researching the social and political implications of contemporary Chinese society during the time the family members lived.

Originality/value

Very little research has been done in the area of Chinese local history and genealogy. The paper would be of value to researchers such as historians, sociologists, ethnologists and archaeologists, as well as students and anyone interested in researching a surname origin, its history and evolution.

Abstract

Purpose

The call for supply chain transparency (SCT), especially the environmental, social and governance (ESG) aspect, is getting increasingly louder. Based on the signaling theory, our study investigates the operational benefit of supply chain transparency in terms of ESG (SCT-ESG). To further clarify the signaling process, the moderating roles of digitalization of the firm and signal strength are also examined.

Design/methodology/approach

Longitudinal secondary data from multiple databases are matched and analyzed using ordinary least squares (OLS) regressions to validate the proposed hypotheses.

Findings

Results suggest that with SCT-ESG, firms have a weakened disparity between production variance and demand variance, and the supply chain experiences a reduced bullwhip effect. Further, digitalization of the focal company and signal strength reinforce the negative effect of SCT-ESG on the bullwhip effect.

Originality/value

The study integrates the SCT and ESG literature through SCT-ESG, extending benefits of ESG disclosure to the supply chain context. It extends the application of the signaling theory in OSCM by including contextual factors of digitalization and signal strength.

Abstract

Purpose

The purpose of this paper is to determine the value of I‐Ching (also called Book of Changes), the ancient Chinese book of wisdom, which has been used for thousands of years to help people make decisions in daily life. Recently, eastern and western scholars have begun discussing how to apply the wisdom of I‐Ching to the field of business administration, particularly decision‐making practices.

Design/methodology/approach

A content analysis method was adopted to uncover possible modern management decision‐making constructs. The single words approach did not find frequently appearing words that integrated decision‐making constructs in the context of I‐Ching. Further uncovering I‐Ching's administrative decision‐making approach, the managerial decision‐making model of I‐Ching is explained, including the premises, the decision contingencies, and the decision process.

Findings

By using an academic comparative analysis method, as it applies to managerial decision making, I‐Ching's early management decision‐making model is subsequently compared with western management decision models, which include rational decision making, bounded‐rationality decision making, intuitive decision making, implicit favorite decision making, and garbage‐can decision making.

Research limitations/implications

The majority of scholars that study I‐Ching focus on “practice divination” research, paying attention to the interpretation or critique of the text only. Unfortunately, related literature based upon a social science research foundation is limited.

Originality/value

The value of I‐Ching was determined to lie in allowing flexibility in the decision‐making process.

Abstract

Purpose

The purpose of this paper is twofold: first, to develop a visualized search system utilizing graphical images to represent the story elements and concepts to help elementary students describe and seek their desired storybooks; and second, to explore the effect of the proposed visualized search system on elementary students’ tactics, success, and motivation for seeking storybooks.

Design/methodology/approach

A quasi-experimental approach was conducted with a sample of 61 elementary students in this study. The students’ tactics, motivation and the success of their storybook searching were addressed as dependent variables for further comparisons of the visualized searching system and a conventional keyword searching system.

Findings

The results revealed that the students in the experimental group exhibited more frequent tactics and greater motivation for storybook searching than those in the control group. Further χ2 analysis indicated a significant relationship between the searching interface and the success of the students’ storybook searching.

Originality/value

This paper proposes a new visual search approach which allows young children to search for storybooks by describing an intended storybook in terms of its characters, objects, or the background colors of the cover page. The findings provide some evidence of the effectiveness of the visualized searching interface in terms of promoting young children’s learning through storybook searching and reading activities.

Abstract

Purpose

The aim of this paper is to examine the effects of light controlling system that combined high refractive particles (n-TiO2 [titanium dioxide – TiO2]) and tartrazine lake dye (TL dye) on thickness, flexural strength, flexural modulus and surface details of the 3D-printed resin.

Design/methodology/approach

Influences of different concentrations of n-TiO2 and TL dye in light-cured resin formulations for 3D printing (3DP) application were evaluated, including curing thickness, flexural strength and surface details under scanning electron microscopy.

Findings

The polymerization thickness of samples containing both n-TiO2 and TL dye was lower compared to samples with TL dye solely. Samples containing more n-TiO2 and more TL dye exhibited lower flexural strength and modulus. Ramp models showed that for samples containing 1 per cent TL dye, when their n-TiO2 content increased from 1 to 5 per cent, surface laminate structures became sharper. However, when the TL dye content doubled to 2 per cent, the surface laminate structures were indefinite compared to 1 per cent TL dye-containing counterparts.

Originality value

In visible-light 3DP, light controlling system in cooperate dye with high refractive particles provides better energy distribution and scattering control. High refractive particles, dyes and light exposure time had influenced the surface resolution and mechanical properties of the 3DP products.
