Effect of slot depth on the evaluation of permeance in the aligned position for identically slotted rectilinear tooth geometry can be carried out using conformal transformations. Consequent increase of permeance is related to the airgap proportion ratios; tooth‐width to tooth‐pitch, t/λ; tooth‐pitch to airgap dimension, λ/g; and slot‐depth to slot‐d/s; through two intermediate parameters. Efficient search routine is used to find a suitable combination of these two parameters corresponding to given proportions of tooth and slot. For λ/g larger than 80 and d/s between 0.3 and 1, the effect of slot depth is negligible, but for λ/g equal to or less than 80 a family of permeance correction factor curves is obtained which may be used to correct for finite slot depth in permeance calculations based on infinitely deep slots. This effect is important in stepping and switched reluctance motors, particularly those with multiple teeth per stator pole.

Method of unaligned permeance determination for a doubly‐salient rectilinear airgap with infinite slot depth is used in order to cover a wider range of gap geometry. The results are arranged in a more convenient form than is available in the literature. A set of new correction factor curves for finite slot depth and taper are then obtained. These data can directly give the unaligned permeance of a rectilinear slotted geometry for given airgap proportions (t/λ and λ/g, where λ is the tooth pitch, t is the tooth width and g is the airgap length). A wide and useful range of airgap proportions are covered, the aim having been to encompass all geometries likely to be of practical importance.

On the surface the subjects of Corporate Social Responsibility (CSR) and Critical Management Studies (CMS) seem to be closely related. Both are concerned with reflecting on the impact of management and organisation on employees, the wider community and the environment. Both suggest that there may be a need for organisations to take responsibility for and account of people other than shareholders and both have used the concept of accountability to suggest that organisations may need to do more than just comply with the legal framework.

This paper aims to contrast two approaches to the study of contracts in business and industrial marketing: first, as a legal document in shaping at the outset exchanges and interactions, for instance in projects; and second, as relational norms in becoming integrated into a business relationship through interactions, for instance as a resource.
The paper draws on cross-case comparison of three projects, as actors develop an engineering service for optimizing the maintenance of large-scale capital equipment by analyzing real-time data from sensors and user records. Comparison is by coding interview and observational data as micro-sequences of interactions among actors.
Preparing contracts allows a project to commence and is an early form of interaction, intensifying new relationships or cutting into and recasting established ones. Relational norms augment and can supersede the early focus on the contract, thus incorporating incremental innovation and absorbing some uncertainties.
The research approach benefits from detailed comparison and captures some variety across its three cases, but the discussion is limited to theoretical generalization.
The analysis and discussion highlights and focuses on when different approaches to understanding contracting are more apparent across durable business relationships. Transitions from a contractual document to a view of relational norms are subtle, vulnerable and not always made successfully.
This paper’s originality is in it comparison of overlapping approaches to understanding businesses’ uses of contacts in business and industrial marketing, of contract and relational norms. It develops a valuable research proposition, in the transition from a mainly contractual to a mainly relational uses of contracts, thus identifying contract as a particular business resource, to be deployed and embedded.
To identify the management tools and variables that impact briefing, assess the nature of current briefing practices, review the need for more structured techniques and determine the place of facilities management in briefing.
A detailed literature review to analyse and critique the briefing process was followed by a brainstorming session to explore relevant technical frameworks. A questionnaire survey investigated opinions of structured approaches to briefing.
The facilities manager operating within the strategic framework of the client organisation and having the necessary skills is a natural choice as brief writer. Facilities managers’ involvement is not strongly reflected in this research, indicating perhaps that they do not consider briefing a natural role or that they do not possess the skills for its undertaking. It is concluded that while briefing remains an unstructured investigative process, the skills for which are learned through experience, then architects and project managers will continue to dominate the activity.
Currently, briefing is unstructured, iterative, and uses a variety of media for its exposition. More formalised processes recognising strategic and project briefing are advocated in the literature. Options for improvement include a structured approach to investigative briefing and facilitated value management.
The limited involvement of facilities managers in briefing prompted this research. This paper identifies the structure and variables impacting the briefing process and concludes with options for formalised approaches to briefing.
THE June conference at Margate is so near that we must needs be pre‐occupied with it at the moment although two months ago we were able to give an anticipatory description of the programme. The protracted and cold winter, culminating in the most “perishing” April of the century, possibly of any century since the Great Ice Age, seems on the threshold of May to have dissolved at last in warmer weather. Margate is a lady in the sun, but perhaps something else under cloud, and wise people take warm clothes when they visit her. We hope, however, that they will not be necessary and that for some hundreds of our readers Margate air will be an invigorating experience.
