Abstract
In this introductory chapter, I discuss the rationale for this edited collection and the contribution it can make to advancing knowledge of gender inequalities and promoting social justice in the medical profession and medical education. I provide a short overview of and critique of popular debates in the medical community in the United Kingdom and I also discuss briefly research about women’s careers in the United Kingdom and globally. The introductory chapter provides a description of each chapter and its contribution to scholarship about gender, careers and inequalities in Medicine/Medical Education.

Abstract
Purpose
The purpose of this paper is to present novel analytical expressions which describe the 3D magnetic field of arbitrarily magnetized triangular‐shaped charged surfaces. These versatile expressions model that the field of triangular‐shaped permanent magnets (PMs) are very suitable to model skewed slotless machines.
Design/methodology/approach
The analytical 3D surface charge method is normally used to provide field expressions for PMs in free space. In this paper, the analytical surface charge integrals are analytically solved for charged right‐triangular surfaces. The resulting field is compared with that obtained by finite element modeling (FEM) and subsequently applied in two examples.
Findings
The comparison with FEM shows that the 3D analytical expressions are very accurate and exhibit very low‐numerical noise. These fast‐solving versatile expressions are therefore considered suitable to model triangular‐shaped or polyhedral‐shaped PMs.
Research limitations/implications
The surface charge method assumes that the relative permeability is equal to 1 and therefore soft‐magnetic materials need to be modeled using the method of images. The PMs are assumed to be ideal in terms of homogeneity, magnetization vector, permeability, demagnetization, and geometrical tolerances.
Practical implications
Many applications, such as the subclass of slotless synchronous linear actuators with a skewed PM structure and planar magnetic bearings, are very suitable to incorporate this modeling technique, since it enables the analysis of a variety of performance data.
Originality/value
As an addition to the common 3D analytical field expressions for cuboidal or cylindrical PMs, this paper presents novel expressions for magnets having triangular surfaces.

Abstract
Previous studies indicate that the use of disability benefits is associated with reduced chances of having children. The current study aimed to identify the bidirectional nature of this association which has been overlooked in previous research. The longitudinal data used in this study were obtained from the Swedish national registers. It consists of 440,200 individuals born from 1968 to 1970 with a follow-up period extending up to 2010. Descriptive analysis, heat map visualization, and multinomial logistic regression were performed. The results show a complex and dynamic association between disability and parenthood. Starting on disability benefits at the age of 20–25 years was associated with a reduced chance of having children during the follow-up duration (≤42 years). Interestingly, another pattern was also revealed, and individuals who had their first child as teenagers (aged 13–19 years) were at higher odds of starting to receive disability benefits during their 30s and 40s compared to the rest of the study population. This is the first study to show evidence of a bidirectional nature of the association between age at starting to use disability benefits and the age of having a first child. Our findings demonstrate the potential of using heatmaps and multinomial regression on time-to-event data to examine bidirectional relationships between various factors investigated across several disciplines.

Abstract
Purpose
The purpose of this paper is to visualize the structure of SCImago Journal & Country Rank (SJR) coverage of the extensive citation network of Scopus journals, examining this bibliometric portal through an alternative approach, applying clustering and visualization techniques to a combination of citation-based links.
Design/methodology/approach
Three SJR journal-journal networks containing direct citation, co-citation and bibliographic coupling links are built. The three networks were then combined into a new one by summing up their values, which were later normalized through geo-normalization measure. Finally, the VOS clustering algorithm was executed and the journal clusters obtained were labeled using original SJR category tags and significant words from journal titles.
Findings
The resultant scientogram displays the SJR structure through a set of communities equivalent to SJR categories that represent the subject contents of the journals they cover. A higher level of aggregation by areas provides a broad view of the SJR structure, facilitating its analysis and visualization at the same time.
Originality/value
This is the first study using Persson’s combination of most popular citation-based links (direct citation, co-citation and bibliographic coupling) in order to develop a scientogram based on Scopus journals from SJR. The integration of the three measures along with performance of the VOS community detection algorithm gave a balanced set of clusters. The resulting scientogram is useful for assessing and validating previous classifications as well as for information retrieval and domain analysis.

Abstract
Purpose
This paper aims to examine relationships between individual‐level values, psychological contracts, and six workplace commitment forms (organizational, occupational, group, work, job, union). It also seeks to examine whether individual values and psychological contracts relate to commitment forms when controlling for demographic variables.
Design/methodology/approach
A total of 313 employees of a major bank in Israel took part in this survey study.
Findings
The findings show that individual values, particularly those that represent more traditional and conservative values, relate to commitment forms above and beyond the effect of the demographic variables. The results also show strong positive relationships between relational contracts and all of the commitment forms.
Research limitations/implications
The study relied upon a snapshot‐in‐time survey design. Such a design consists of a single observation with no control group and limited control over the effects of variables. Also, only one professional group, bank employees, was examined here, and one should be cautious about generalizing the results to other occupational groups.
Originality/value
An important contribution of this study is the examination of the psychological contract in its relationship to commitment, a relationship thus far little examined in the literature. Another important contribution of this study is its exploration of how psychological contracts relate to other forms of commitment in addition to organizational commitment.

Abstract
Purpose
The purpose of this paper is to increase one's understanding of psychological contracts by proposing and testing relationships between employees' personalities and their psychological contracts and to consider the influence of gender on psychological contracts.
Design/methodology/approach
Data were collected from 163 employees in ten organizations. Regression analysis was used to explore the relationships between each of nine psychological contract dimensions plus gender and the Big Five personality dimensions.
Findings
It was found that personality is related to five of the nine psychological contract dimensions and that each personality dimension is related to one or more of the psychological contract dimensions. It was also found that gender had a significant impact on our results. Women held stronger obligation attitudes than did men. The personality of men related to varying obligation attitudes, whereas, women's attitudes did not vary significantly within personality dimensions. The study suggests that employees' psychological contracts may be more emotionally based than cognitively based.
Research limitations/implications
The self selection of participants limits the generalizability of the results. The data is cross‐sectional precluding inference of causality. The paper assumed a linear career model for participants and did not consider alternate models
Practical implications
Personality would appear to be an important factor in our understanding of psychological contracts, particularly in men. Personality provides a basis for psychological contracts being idiosyncratic. The interaction of personality and gender complicates the psychological contract management process.
Originality/value
Despite 17 years of research, the factors underlying employees' idiosyncratic psychological contracts remain to be adequately explored through empirical research. This is the first study that connects employees' personality to their beliefs about employee and organizational obligations. Gender appears to play a role in the development of psychological contracts.

Abstract
Purpose
This paper aims to introduce a systematic computing and analytical procedure that is applied to the co-author network to identify the temporal evolution and growth of research collaborations in the area of e-governance. The empirical analysis of the temporal co-author network can trace the emerging authors and knowledge bursts over time.
Design/methodology/approach
The study applied social network theory to trace the author collaboration patterns in the domain of e-governance. Analysis of the co-author network using micro and macro parameters was done to trace the temporal evolution of the author collaborations.
Findings
E-governance is a multi-disciplinary research domain split over streams of management, politics, information technology and electronics. Hence, research collaborations play a significant role in its advancement. The knowledge sharing between individual authors, institutions and groups through research collaborations, resulting in extensive sharing of data, equipment and research methods, has boosted research activities and development in e-governance. In this paper, the authors systematically analyse the current scenario of research collaborations in the area of e-governance using co-author network to estimate its impact on the advancement of the field. The authors also analysed the temporal evolution of the co-author networks, which show remarkable growth of research collaborations in the domain of e-governance from the year 2000.
Research limitations/implications
The co-author network analysis is only a proxy measure for the analysis of research collaborations. The names of the authors and the university affiliations used in the article are as retrieved from the research repository of Scopus. The degree, citations and other parameters related with authors have scope only within the environment of the co-author network used in the analysis. The criteria used in the study is limited to the degree of research collaborations and the number of co-authored publications in the giant component of the co-author network.
Practical implications
Institutions, authors and governments can trace and select suitable topics and choose research groups of co-authors over the world for future research collaborations in e-governance. The knowledge about the emerging and most discussed topics gives an overview of the global research trends of e-governance.
Social implications
The study identified the evolution of creative collaborations in e-governance in the global perspective. The methodology introduced here is helpful to detect the proficient and productive author collaborations and the spectrum of related e-governance research topics associated with them. As the author collaborations can be mapped to the institutional and country-level collaborations, the information is helpful for researchers, institutions and governments to establish the best collaborations in e-governance research based on the author proficiency, collaboration patterns and research topics as per the requirements.
Originality/value
The paper introduces a novel research methodology using temporal analysis of co-author network to identify the evolution of research patterns and the associated research topics.
