Abstract

Purpose

The automotive industry extensively uses switched reluctance motors (SRM) because of their excellent performance. The main purpose of this article is to investigate the design of a particular type of SRM called doubly salient outer rotor switched reluctance motor (DSORSRM) for electric vehicle application in this paper.

Design/methodology/approach

Different configurations of DSORSRM motor such as long flux path SRM, reduced flux path mutually coupled SRM and short flux path SRM (SF-SRM) are considered for investigation. The best configuration based on average torque is selected for further investigation by conducting an electromagnetic analysis. Also, in the proposed design, laminating material with low iron loss and superior performance characteristics is selected by doing electromagnetic analysis for SRM with M19, M660-50D, M-19 and M800-100A non-oriented laminating core material. Because vibrations are produced in DSORSRM devices as a result of changing induction, a mechanical analysis was performed to estimate the natural frequencies of vibration and the amplitudes that may lead to acoustic noises.

Findings

SF-SRM configuration with three-phase, 12/10, 250 W, 48 V, 1,000 rpm is selected with the impact in the elimination of flux reversals and also has various salient features such as singly excited, no rotor windings, no permanent magnet, pure in construction and high starting torque. Still, this SRM suffers from vibration owing to changing induction. In lamination material selection, M19 is chosen as optimized material to obtain vibration reduction. Vibration analysis was performed for the optimized 12/10 SF-SRM with M19 lamination material, and the corresponding modes for the machine to operate with reduced vibration are analyzed. The current and speed characteristics of the prototype model for the DSORSRM motor are obtained and validated with finite element analysis (FEA) results.

Originality/value

The performed FEA result shows that the proposed DSORSRM with short flux path configuration produces a high average torque of 1.915 N m. The M19 lamination material gives a minimum iron loss of 9.056 W. The modal frequencies are estimated and validated with numerical equations.

Abstract

AEG has extended its range of avionic CRTs by introducing a new 4.5″ × 6″ rectangular screen cockpit tube. The M19‐E845 is an extremely bright ultra‐high‐resolution colour tube, which is available as a self‐contained unit and has already proved successful in extensive flight trials. For example, three units are being used as interactive multi‐function displays in the British Aerospace ‘Experimental Aircraft Programme’, the overall display system being supplied by Smith's Industries.

Abstract

The national logistics policy report published by Ministry of Land, Infrastructure and Tourism in 2011 proposes to establish international logistics strategy teams in 10 different regions around Japan to satisfy the increasing demand for advance transportation infrastructure and stay competitive in Asia Pacific. The globalization of world economies creates many opportunities as well as challenges for international logistics companies to gain more business chances in this changing environment. The purpose of this paper is to improve service quality of international logistics companies and explores the quality function deployment in terms of quality evaluation method. The logistics service is particularly characterized by offering a series of transport solution and including other logistics activities. The major customers of the logistics services are the industrial clients. The customer satisfaction is key managerial mission since the competitiveness is a growing issue in this industry. The quality function deployment is one of the unique procedures to expose the requirements of customer and transform them into managerial tasks by cross correlation analysis between requirements and technical measures. The empirical study is performed to investigate service quality of the logistics industry by focusing on a group of leading logistics companies.

Abstract

Purpose

The purpose of this paper is to explore self-management among informal tourism employees in urban China with the theoretical basis of Jianghu and reveal the forming process and operation mechanism of China’s urban informal organizations’ self-management.

Design/methodology/approach

This paper adopts process–event analysis of informal tourism photographers surrounding Guangzhou Tower. Conducting field inspection and in-depth interviews, the forming process is analyzed and typical events are captured to unveil this self-management mechanism.

Findings

The self-management of informal tourism employees in China is based on the Jianghu theory, which specifies the role, obligation and responsibility of a member. These above rely on word-of-mouth order or implicit ways to treat newcomers, realize internal communication and deal with public affairs. Brotherhood, benevolence and etiquette make up the core values of the Jianghu theory that advises strategies in dealing with different events. This self-management, based on the Jianghu theory, has not only effectively solved internal conflicts, but has also achieved the goal of social management.

Originality/value

Informal employees’ self-management is extremely important due to the high cost of government intervention. Through China’s urban informal tourism employees’ Jianghu-styled self-management, the paper shows that the government should not crack down on this group indiscriminately. Instead, it should, through the management agent, set up effective Jianghu rules to realize regular control over this group.

Abstract

This article reviews the international literature of the last two decades on self‐injurious behaviour in prisons and jails and introduces the risk factors associated with this behaviour. Studies from a variety of countries investigated different samples (e.g. in jails or prisons; female or male inmates). We only chose those studies using a control group of inmates without self‐injurious behaviour. The findings on potential risk factors for self‐injurious behaviour are largely contradictory because of the differences in sample selection and dependent variables (deliberate self‐harm without suicidal intent vs. suicide attempts). We also discuss some methodological problems in predicting self‐injurious behaviour.

Abstract

Purpose

The academic–practitioner gap has been a widely discussed and well-established issue. Despite numerous studies conducted in this area, empirical evidence reveals that the gap is widening and also emphasizes the exigency to bridge this gap. Hence, the purpose of this study is to propose an acceptable solution that will fill this lacuna.

Design/methodology/approach

The study adopts the qualitative research methodology and was based on the system theory (ST) and the institutional theory (IT). Interviews, based on a semi-structured questionnaire, were conducted, focusing on three categories, namely individuals with solely academic experience, individuals with both academic and industrial exposure and business leaders. The unit of analysis was the individual.

Findings

The study, which unearthed some rich and challenging evidence from the respondents, reveals that gaining industrial exposure and working on continuous professional development are vital for academics to narrow or even close this gap. In addition, serving as apex members at board level or in professional bodies, serving global organizations as lead consultants and working on research collaborations are other important dimensions for academics.

Practical implications

This study introduces an emerging model named the “Pentagon Model” and develops a corporate index (C-index) for academics to earn, similar to the h-index. The study also explains the operationalization of the C-index based on the proposed algorithm. Hence, it is the envisaged that this study will change the landscape of the academic sphere in practical terms.

Originality/value

This study was carried out with the sole intention of bridging the gap between academics and practitioners. The proposed model and the index, which were developed by the author purely based on the outcome of this study, pave the way for many future research studies, not only to further improve the C-index but also to minimize disparities in transdisciplinary work between academics and practitioners.

Abstract

Drawing on insights from a yearlong ethnography and in-depth survey of the members of a Buddhist monastery located in the heart of modern Europe, we examine how members of the organization come to be more or less involved in the organization and in its core institutional logic. Here we present an exploratory analysis of how individuals’ beliefs about Buddhism and its relationship to everyday life are deeply intertwined with and articulated into different regimes of organizational activities, rituals, and religious practices. Borrowing from institutional logics theory, we use methods for illustrating the relational structure that articulates dualities linking beliefs and practices together. We show that dually ordered assemblages can reveal different types of logics embraced by different members of an organization. Our principal contention is that the greater the structural alignment between an individual’s belief structure, their repertoire of practices, and the institutional logic of the organization, the more well integrated that individual will likely be within the organization, the higher the probability of transformational changes of personal identity, as well as the greater probability of overall success in organizational membership recruitment and retention.

Abstract

Purpose

Greening existing buildings (GEB) considerably improves energy efficiency of old buildings, along with other benefits, but it is not widely practiced. As a part of a wider study, this paper aims to evaluate the perception of building dwellers/owners on the challenges and motivators to GEB in Brunei Darussalam.

Design/methodology/approach

A structured questionnaire survey collected 109 responses from building owners/dwellers. Cronbach's alpha tested the reliability of the data collected. One-sample t-test examined if sample means are consistent with population means. ANOVA examined if different respondent groups significantly agreed on the importance levels of individual factors. Moreover, factor analysis narrowed down the long list of factors in to a smaller number of components.

Findings

A set of 30 challenges and 19 motivators of GEB was identified. “Lack of a GEB infrastructure” was identified as the collective key challenge, leading dwellers to recognize lack of support and knowledge and develop wrong perception on GEB. However, “framework of supports,” as a summative motivator, improves knowledge and awareness on GEB, which allows recognizing other benefits and developing a momentum of practicing GEB. Factor analysis suggested a consolidated approach for challenges through six interrelated components, but for motivators to focus on somewhat four independent areas.

Originality/value

House/building dweller/owners' decision is the key to undertake GEB. This study, apparently for the first time, contributes to identifying the challenges and motivators that influence their decision-making.

Abstract

Purpose

Esthetic trend changes with the development of society and cultural differences. A minimizer bra designed to make breasts appear smaller is now popular with large-breasted women in China. To conform to the requirements of modern aesthetics in China, this paper aims to investigate vital features of breast appearance that influence people’s subjective evaluation of breast size and analyze how bra design parameters affect breast shape and make breasts appear smaller.

Design/methodology/approach

This study used 3D scanning technology and reverse engineering software to obtain objective breast measurements in detail. A subjective evaluation experiment was conducted to evaluate the overall performance of seven minimizer bras compared to a basic comparison bra. Around 20 design parameters of 8 sample bras were identified to make a further study about the correlation between bra design features and breast shaping effect. To gain a deeper understanding of how bras interact with breast tissue, this study presented heat maps of the breast surface to visualize the deformation of breast shape.

Findings

Nine breasts' characteristics, such as the distance between bust points, breast depth, outer breast curvature and slope, etc. have been determined to be highly correlated with the visual reduction effect of breasts. In addition, for the bras in this experiment, the high-performance bra for women with large breasts tends to have a wider side panel, a wider under band, higher gore and a stronger transverse rigidity of the bra cup. According to the observation of heat maps of the breast surface, soft full-figure bras provide a wider range of compression to the breasts and effectively flatten the breasts.

Originality/value

This paper first aimed at the need to shape the ideal breast appearance for large-breasted women and make a further study of several hot-selling minimizer bras in China. The suggestions given in this paper help lingerie manufacturers better understand how design features of bras can affect their shaping effect and improve the wearing effect of minimizer bras for large-breasted women.

Abstract

Purpose

The acceleration of globalized commerce and economic activities has meant that conventional and Shariah (Islamic law) compliant organizations transact and negotiate among themselves. Therefore, this study aims to explore the concept of corporate negotiation and the communicative principles that guide the negotiation process among Shariah-compliant organizations.

Design/methodology/approach

The study uses a qualitative method through an inductive interpretative approach by conducting 20 in-depth interviews among four groups of experts. These consist of three muftis, ten academicians in Islamic assets, finance and asset jurisprudence; three practitioners in charge of inter-organizational negotiation and decision-making; and four shariah board members of selected Islamic banks.

Findings

The findings reported that business negotiation is used by Islamic organizations for reconciliation, consultation, resolving disagreements and as a means of achieving spiritual satisfaction. Furthermore, the key communicative principles of the negotiation process consist of the credibility of informational exchange, flexible interactions and the openness and truthful disclosure of information.

Research limitations/implications

The empirical data discussed in this study supports the claim that macro-environmental factors and social and cultural values should be considered when examining business negotiating behaviors. However, this study focuses only on the banking/service organization negotiation. Therefore, future research should focus on the Islamic negotiation process in the context of diplomatic and international relations.

Practical implications

The findings reported in this study offer insight for negotiators operating among Islamic organizations to understand the principles and process of negotiation in the purview of Shariah standards and principles.

Originality/value

In terms of theoretical implications, this study reveals a clear conceptual difference between the conventional concept and the Islamic perspective of corporate negotiation. Also, this study highlights the impact of organizational culture, specifically Islamic management strategies, on the business negotiation process and business communication principles.
