Abstract
Purpose
The purpose of this paper is to optimise the cost‐based performance of a tubular linear generator and to minimise cogging forces.
Design/methodology/approach
Optimisation of a tubular linear generator with longitudinal flux topology has been undertaken using a finite element method. The computational models used have been verified experimentally.
Findings
The use of an oversized stator linear generator design as opposed to an oversized translator design has the potential to increase the output electromotive force per unit material cost by 25 per cent for slotless iron core topologies and approximately 14 per cent for air core topologies. For cogging force minimisation, optimisation of the length of the stator core is an effective technique for both oversized stator and oversized translator constructions. Comparisons of magnet materials also indicate that the higher cost of rare earth magnets to ferrites is compensated by their superior specific performances.
Originality/value
In this paper, a broader range of design parameters than in previous investigations has been optimised for the slotless iron core and air core topologies. The result relating to cogging force reduction and cost savings (in particular) has the potential to make direct drive wave energy extraction a more competitive technology in terms of reliability and cost.

Abstract
The Howard Shuttering Contractors case throws considerable light on the importance which the tribunals attach to warnings before dismissing an employee. In this case the tribunal took great pains to interpret the intention of the parties to the different site agreements, and it came to the conclusion that the agreed procedure was not followed. One other matter, which must be particularly noted by employers, is that where a final warning is required, this final warning must be “a warning”, and not the actual dismissal. So that where, for example, three warnings are to be given, the third must be a “warning”. It is after the employee has misconducted himself thereafter that the employer may dismiss.

Abstract
The environment surrounding U.S. higher education has changed substantially over the past 40 years. However, we have a limited understanding of what these changes mean for the higher education organizations (HEOs) that occupy this organizational field. In this paper, I use descriptive statistics and multilevel latent class analysis (MLCA) to analyze the financial behaviors of public four-year HEOs from 1986 to 2010 to evaluate how HEOs adapt financially to their changing environments. I advance the current conceptual and empirical understanding of public HEO behaviors by evaluating how public HEOs utilize combinations of revenue and spending streams to accomplish their mission and the extent to which the revenues and spending patterns of these institutions are related. Descriptive results confirm the shift away from state funding toward tuition revenues and the relative stability in spending patterns. MLCA results, which allow for the investigation of how combinations of revenue and spending streams work together, indicate that public HEOs are changing the combinations of revenues they rely on in different ways, revealing multiple specific pathways for how public HEOs adapt to their changing environments. The spending profiles, in contrast, remain stable with only a few HEOs changing their profile over time. I argue that the loose coupling between revenues and spending and discontinuity in their patterns of change over time suggests that public HEOs are able to establish a buffer between their environment and spending or activities that allows them to continue engaging in the same broad set of activities despite environmental changes.

Abstract
Civil wrongdoings with consequent financial and other loss or damage to employers, employees and third parties may result in the course of various trade union activities. These day to day trade union activities take a variety of forms. The most common ones are inducement of breach of contract, conspiracy, trespass, nuisance, and intimidation. Each of these activities constitutes a tort which, unless the statutory immunities apply, would normally give rise at common law to an action for damages or, as is more frequent, enable the aggrieved party to obtain an injunction.

Abstract
A distinction must be drawn between a dismissal on the one hand, and on the other a repudiation of a contract of employment as a result of a breach of a fundamental term of that contract. When such a repudiation has been accepted by the innocent party then a termination of employment takes place. Such termination does not constitute dismissal (see London v. James Laidlaw & Sons Ltd (1974) IRLR 136 and Gannon v. J. C. Firth (1976) IRLR 415 EAT).

Abstract
Purpose
The purpose of this paper is to reflect, personally, regarding work, politically and theoretically, on 40 years of involvement in organization studies, profeminism and intersectionality.
Design/methodology/approach
The paper uses autoethnography.
Findings
The paper shows the need for a broad notion of the field and fieldwork, the development of intersectional thinking, the complexity of men's relations to feminism and intersectionality and the need to both name and deconstruct men in the research field.
Research limitations/implications
The paper suggests a more explicit naming and deconstruction of men and other intersectional social categories in doing research.
Practical implications
The paper suggests a more explicit naming and deconstruction of men and other intersectional social categories in equality practice.
Social implications
The paper suggests a more explicit naming and deconstruction of men and other intersectional social categories in social, political and policy interventions.
Originality/value
The paper points to recent historical changes in the connections between feminism, gender, profeminism, organizations and intersectionality in relation to equality, diversity and inclusion.

Abstract
Purpose
David Peace’s Red Riding quartet ( 1974; 1977; 1980; 1983 ) was published in the UK between 1999 and 2002. The novels are an excoriating portrayal of the violences of men, focusing on paedophilia and child murder, the hunt for the Yorkshire Ripper and, predominantly, the blurring of boundaries between the activities of police officers, criminals and entrepreneurs. This chapter aims to examine the way in which the criminal entrepreneur draws on socially constructed ideas of masculinity and the capitalist ideal in order to establish identity. This will be achieved through an examination of John Dawson, a character central to the UK Channel Four/Screen Yorkshire’s Red Riding Trilogy, the filmed version of the novels, first screened in 2009. The central role of networks of powerful men in creating space for the criminal entrepreneur and the cultural similarities between police officers and criminal entrepreneur will be explored.
Methodology/approach
Using the research approach of bricolage, the chapter provides a reflexive commentary on the films, drawing on a number of other texts and sources, including news accounts of featured events and interviews with the author David Peace and the series co-producer Jamie Nuttgens – an analysis of the texts, using a framework suggested by van Dijk (1993) and McKee (2003) features.
Findings
The centrality of the idea of hegemonic masculinity to the activities of both police officers, and criminals and businessmen and Hearn’s (2004) assertion that the cultural ideal and institutional power are inextricably linked are examined through an analysis of the role of Dawson (and his three linked characters in the novels) in the Red Riding Trilogy.
Research limitations/implications
The chapter provides an analysis of one film series but could provide a template to apply to other texts in relation to topic.
Social implications
The social implications of the findings of the research are discussed in relation to work on the impact of media representations (Dyer, 1993; Hall, 1997).
Original/value
It is intended that the chapter will add to the growing body of academic work on the criminal entrepreneur and the ways in which media representation of particular groups may impact on public perception and construction of social policy.

Abstract
In order to succeed in an action under the Equal Pay Act 1970, should the woman and the man be employed by the same employer on like work at the same time or would the woman still be covered by the Act if she were employed on like work in succession to the man? This is the question which had to be solved in Macarthys Ltd v. Smith. Unfortunately it was not. Their Lordships interpreted the relevant section in different ways and since Article 119 of the Treaty of Rome was also subject to different interpretations, the case has been referred to the European Court of Justice.
