Abstract

Purpose

The purpose of this paper is to analyze the influence of different types of winding configurations on the distribution of leakage field and branch currents for a 330-kVA high-temperature superconducting (HTS) transformer winding.

Design/methodology/approach

A three-dimensional electromagnetic model coupled with a circuit model validated by an experiment is developed to calculate the leakage field and current uniformity under four different types of secondary winding configurations. The four types of gaps between secondary windings are uniform gap, arithmetic progression (AP) gap, six sections with three different gaps and eight sections with four different gaps. A coefficient named as uneven degree is used to define the current nonuniformity.

Findings

The simulation results show that the currents and leakage field of double pancakes (DPs) on both sides are larger than those of the other DPs, and the currents of several middle DPs are smaller than the average rated current with an ISOB gap and larger than the average rated current with an IBOS gap. For any one of the four types of winding configurations, the type with the ISOB gap can prohibit the current nonuniformity more effectively, whereas the IBOS gap can decrease the leakage field more. The AP with the ISOB gap is a wise choice for decreasing the uneven degree and leakage field.

Practical implications

There is an optimal winding configuration for decreasing the leakage field and uneven degree of branch currents. The results and numerical model are very useful for the design of a HTS transformer.

Originality/value

The leakage field distribution and branch currents nonuniformity for 25 parallel DPs are investigated and optimized.

Abstract

Describes a study which examined the relationship of employment gaps to measures of work outcomes and emotion wellbeing. Data were collected from a diverse sample of 792 managerial and professional women using questionnaires completed anonymously. Managerial women with more employment gaps were older, more likely married, had more children if married, earned less income and worked fewer hours and extra‐hours per week. Women with more employment gaps also reported less career satisfaction, less job involvement and less optimistic career prospects. Employment gaps were not, however, related to psychological wellbeing. Women reporting more employment gaps earned less income though having more work experience and similar educational qualifications and credentials.

Abstract

The purpose of this study is to increase understanding of the dynamics of gaps in buyer‐seller relationships. Increasingly complex, fast changing, and dynamic business environments provide a rich research environment for analysing dynamics of gaps in business relationships. Traditionally gaps have been examined from the static and single party perspective. However, dyadic buyer‐seller relationships can be revealed, described, and analysed in new ways by viewing intraorganisational and interorganisational gaps longitudinally as chains of interactions in relationships and from the perspectives of several parties. The dynamic gaps of the relationships are described and analysed longitudinally from the perspective of gaps for the first time.

Abstract

A test procedure was developed to assess the capillary flow wettability of solders inside a confined geometry. The test geometry comprised two parallel plates with a controlled gap of constant thickness (0.008 cm, 0.018 cm, 0.025 cm and 0.038 cm). Capillary flow was assessed by: (1) the meniscus or capillary rise of the solder within the gap; (2) the extent of void formation in the gap; and (3) the time dependence of the risen solder film. Tests were performed with the lead‐free solders 95Sn‐5Sb, 96.5Sn‐3.5Ag, and 91.84Sn‐3.33Ag‐4.83Bi. The capillary rise of the lead‐free solders was less than that observed with the 63Sn‐37Pb control. Reducing the solder surface tension and contact angle improved capillary flow. Void formation by the non lead solders increased as the gap became smaller. The extent of voiding was determined primarily by the gap size rather than the wettability parameters (contact angle or surface tension) of the individual alloys.

Abstract

Purpose

Nowadays, to simplify manufacture process and improve fault-tolerant capability, more and more modular electrical machines are being applied in industrial areas. The purpose of this paper is to investigate a novel modular single-sided flat permanent magnet linear synchronous motor (PMLSM), which adopts segmented armature with the required flux gaps between segments to enhance the performance.

Design/methodology/approach

Using 2D finite element analysis, the performances, such as open-flux linkage, back-EMF, average thrust force, thrust ripple, etc., are compared in different values of flux gaps, as well as different slot/pole number combinations (mainly odd numbers of poles). Finally, to show the difference of linear motor from rotary one, the detailed comparison is made between modular PMLSM and rotary PMSM.

Findings

Due to flux gaps, it is found the electromagnetic performances are worsened along with flux gap width increasing to modular PMLSMs having slot number higher than pole number, but some aspects of performances such as winding factor, open-circuit flux linkage, back-EMF and average thrust can be improved to those having slot number lower than pole number. Due to the end effect of linear format, the thrust ripple is not significantly improved.

Originality/value

It is concluded the proper flux gaps can be chosen to improve the performance of PMLSM with certain slot/pole combinations. A new structure of 12-slot-13-pole (hereinafter referred to as 12s/13p) PMLSM with fractional slot and alternative-teeth wound winding is designed.

Abstract

Purpose

Investors and financial statement users may have differing beliefs about the responsibility of an independent accounting firm performing an audit of a client's financial statements. This study aims to investigate the existence of an audit expectation gap between auditors and financial statement users in Egypt.

Design/methodology/approach

The research method adopted in this study is identical to that used by Schelluch, Best et al. and Fadzly and Ahmed.

Findings

The results found evidence of a wide audit expectation gap in Egypt in the areas of auditor responsibilities for fraud prevention, maintenance of accounting records, and auditor judgment in the selection of audit procedures. To a lesser extent, an expectation gap was found concerning the reliability of audit and audited financial statements, and the usefulness of audit.

Research limitations/implications

The different economic and cultural conditions in Egypt may restrict the generalisability of this study.

Practical implications

In order to reduce the expectation gap and improve decision‐making by financial statement users, the results of this study support the adoption of the long‐form audit report, augmentation of the auditing framework, strengthening of the auditor's integrity, and finally educating users on the nature and functions of audit.

Originality/value

This paper contributes to the understanding of the diverse nature of the expectations gap by examining the different economic and cultural setting of Egypt.

Abstract

Purpose

The purpose of this paper is to find alternative strategies to change negative output gaps in China.

Design/methodology/approach

A path Philips curves approach is proposed to investigate output gaps, which develops hybrid Philips curves with the control variables of money, house prices and interest rates.

Findings

An alternative strategy to stop the decline in output gaps rate is to perform interest rate, house price, and money growth rate about 3, 1 and 15 percent, respectively. The results also indicate that only one of monetary increase, changes in interest rates, and house price adjustments are difficult to change the negative output gap.

Practical implications

Alternative strategies cannot only change the negative output gap, but also succeed in pushing the inflation rate down to 3 percent.

Originality/value

This study provides a new path Philips curves to simulate how the macroscopic control variables influence output and inflation. It provides a useful insight for stopping the decline in output gaps.

Abstract

Purpose

This article focuses on children’s social quality. Social quality can be understood as the extent to which people can engage in the social, economic, and cultural lives of their communities, under conditions that strengthen their well-being and potential. This article has two purposes. The first is to develop a league table ranking 23 countries’ children’s social quality based on comparative data. The second is to examine the correlation between these countries' commitment to promoting children’s social quality and reducing the child care gap, where childcare is insufficiently covered by child care leave or Early Childhood Education and Care.

Design/methodology/approach

We analyse the findings obtained from the children’s social quality league table and the child care gap league table for the 23 countries.

Findings

The findings reveal mixed relationships between the children’s social quality league table and the child care gap league table. These findings indicate that we cannot assume that countries prioritizing the reduction of the child care gap automatically possess the capacity or willingness to promote other aspects of children’s welfare. They also highlight the significance of encouraging countries to enhance their children’s social quality as a way to promote children’s welfare rather than solely reducing the child care gap.

Originality/value

Children’s social quality is a new research area. To explore it, this article makes an innovative attempt by exploring the connection between social quality, children’s welfare, and the child care gap. The league table of children’s social quality this article developed is the first of its kind.

Abstract

Purpose

The primary aim of this paper is to illuminate the critical issue of the degree awarding gap in the UK, which significantly impacts students from lower socio-economic backgrounds and minority groups. By conducting a systematic review of existing literature following the PRISMA protocol, this study seeks to uncover the complex web of explanatory factors that mediate the relationship between contextual indicators, institutional culture, and degree awarding disparities. Addressing this gap is vital for promoting social justice, enhancing the economy, safeguarding the reputation of UK universities, and adhering to legal responsibilities. This paper endeavours to provide a comprehensive understanding of the underlying causes of degree awarding gaps and offer evidence-based recommendations for the higher education sector to mitigate these disparities.

Design/methodology/approach

This study employs a systematic review design, adhering to the PRISMA protocol, to meticulously analyse the existing body of literature concerning the degree awarding gap in UK higher education. By systematically gathering, evaluating, and synthesizing relevant studies, the review aims to identify and understand the multifaceted factors mediating the link between contextual indicators, institutional culture, and the disparities observed in degree awarding. This methodological approach ensures a rigorous and transparent examination of the literature, enabling the identification of both the breadth and depth of research on the topic. Through this design, the paper aspires to uncover nuanced insights into the mechanisms driving degree awarding gaps.

Findings

The review’s findings reveal that degree awarding gaps in UK universities are influenced by a constellation of factors, highlighting the complexity of this issue. Key among these are unconscious bias, limited student engagement opportunities with academic staff, institutional racism, inadequate support systems, and a scarcity of social and cultural capital. These factors collectively contribute to significant disparities in degree outcomes, disproportionately disadvantaging students from lower socio-economic backgrounds and minority groups. The evidence suggests that institutional practices and culture play a pivotal role in either exacerbating or alleviating these disparities, indicating the need for targeted interventions to address the root causes of degree awarding gaps.

Research limitations/implications

One strength of conducting a systematic review is its rigorous and meticulous nature, which ensures that the process is carefully planned and executed. This comprehensive approach allows for the elimination of biases, as the review systematically gathers and analyses existing literature on the topic. By adhering to a structured methodology, the systematic review enhances the validity and reliability of the findings, providing a robust and unbiased synthesis of the available evidence. This strength lends credibility to the research and reinforces the confidence in the conclusions drawn from the review.

Practical implications

The practical implications arising from this information indicate that universities need to address the identified issues directly by implementing supportive strategies and interventions. By doing so, they can create a learning environment that is more inclusive and equitable, allowing all students to unlock their full potential. This may involve measures such as raising awareness about unconscious bias, promoting engagement between academic staff and students, implementing anti-racist policies, establishing comprehensive support systems, and actively fostering social and cultural capital. Such practical actions will contribute to reducing the degree awarding gaps and promoting equal opportunities for all students, ultimately leading to a more equitable and successful educational experience.

Social implications

The social implications derived from this information are significant. By implementing supportive strategies and interventions to address the identified issues, universities can contribute to creating a more inclusive and equitable learning environment. This has the potential to have a transformative impact on society by providing equal opportunities for all students to unlock their full potential. By raising awareness about unconscious bias and implementing anti-racist policies, universities can foster a more diverse and inclusive community. Promoting engagement between academic staff and students and establishing comprehensive support systems can enhance social cohesion and create a sense of belonging. Ultimately, these efforts can lead to reduced degree awarding gaps and contribute to a more equitable and successful educational experience, positively influencing broader social equality and cohesion.

Originality/value

This paper contributes significantly to the literature by offering a comprehensive, systematic review of the factors contributing to the degree awarding gap in UK higher education, highlighting its originality and value. By focusing on the interplay between contextual indicators, institutional culture, and degree awarding disparities, the study provides novel insights into how these dynamics contribute to educational inequities. Furthermore, the evidence-based recommendations for institutional interventions presented in this paper furnish the higher education sector with actionable strategies to foster a more inclusive and equitable learning environment. This work not only advances academic understanding of degree awarding gaps but also offers practical value to policymakers and educational institutions aiming to enhance social justice in higher education.
