Abstract
In recent years, a novel method for computing loadflow orientations and loadpaths, which is based on iterative solutions of non‐linear equations and finite element results, has emerged in the literature. In the present investigation, the prior formulation and approach has been enhanced by deriving explicit expressions for computing loadflow orientations. The new equations produce more accurate loadflow orientations and improve the fidelity of calculated loadpaths. In particular, for a typical loaded plate containing a hole, the density of loadflow lines is also shown to provide accurate values of stress concentration factor. Subsequently, loadflow visualisation for biaxially loaded plates containing non‐optimal and optimal holes is undertaken to identify key features of the stress distributions. It is found that regions of “recirculation” are apparent for non‐optimal hole shapes, whereas no recirculation zones are present for optimal shapes. In general, it is considered that loadflow visualisation is a simple but powerful tool for use by structural designers and analysts.

Abstract
Design engineers use the term load path to describe, in general terms, the way in which loads path through a structure from the points of application to the points where they are reacted. In contrast, stress trajectories are more clearly identified by the direction of the principal stress vectors at a point. The first author proposed a simple definition of the term load path in 1995 and proposed procedures to determine load paths from two‐dimensional finite element solutions. In this paper, the concept of load paths will be further explored and related to stress trajectories and Michell structures. The insight given when determining the load transfer near a pin‐loaded hole will be demonstrated. In addition a cantilevered beam will be considered and an introduction to plotting load paths in three‐dimensional structures is given.

Abstract
A procedure for plotting load paths and load flow in structures from a finite element analysis is described. The load flow is indicated by pointing vectors and the load paths are determined by plotting contours tangent to these vectors. The procedure is applied to assembled structures. An explanation is given for “eddies” that can appear in regions not contributing to the load path.

Abstract
Gives an in depth view of the strategies pursued by the world’s leading chief executive officers in an attempt to provide guidance to new chief executives of today. Considers the marketing strategies employed, together with the organizational structures used and looks at the universal concepts that can be applied to any product. Uses anecdotal evidence to formulate a number of theories which can be used to compare your company with the best in the world. Presents initial survival strategies and then looks at ways companies can broaden their boundaries through manipulation and choice. Covers a huge variety of case studies and examples together with a substantial question and answer section.

Abstract
Purpose
This paper aims to make an assessment of the contribution made by accounting histories of women produced since 1992 and the current state of knowledge production in this subject area.
Design/methodology/approach
The study is based on a review of published sources on accounting history and women's, gender and feminist history.
Findings
Whereas feminist historians and historians of gender boast substantial advances in research and transformative impacts on the wider discipline of history, similar momentum is less evident in accounting history. It is argued that over the past 15 years scholarship has remained substantially in the “recovery” phase, has not “defamiliarized” the sub‐field and is yet to engage with developments in feminist and gender historiography which offer regenerative potential.
Research limitations/implications
The paper argues that sex and gender differentiation persist in both the past and the present and their study should feature large on the accounting history research agenda.
Originality/value
Core themes in feminist and gender history are explored with a view to identifying research questions for accounting historians. These themes include the oppression and subordination of women, the public‐private divide, restoring women to history, devising new periodisations, investigating socio‐cultural relations, and the construction of identities.

Abstract
In recent years there has been an increasing focus on improving the physical health of people with serious mental illness and many policies and guidelines are now tailored to support professionals working in mental health services to meet these requirements. We found, however, that the physical health care policies produced by mental health trusts in England varied enormously. Policies were often cumbersome, vague and lacked clear guidance on what particular action should be taken, when it should be taken, and by whom. Physical health care policy documents of three mental health care trusts in the north sector of the East Midlands Strategic Health Authority (UK) were examined in detail. We found significant disparities between the policies in terms of size, readability, external references and reading cost. None could be read swiftly and all incorporated vague language into their directives. It would be beneficial for there to be more consideration given to forming local policies that are readable, succinct, and unambiguous. There is potential for considerable economy of effort with collaboration in production of these documents.

Abstract
It is commonly acknowledged that history matters in strategy. However, the strategy literature mainly discusses history in terms of path dependency, leaving little room for managerial agency, despite growing anecdotal evidence that managers can actively draw on corporate history to improve decision-making. An emerging literature on how managers use the past to give sense to internal and external stakeholders has given rise to a more agent-based approach to history, but while sense-giving is commonly connected to sense-making as a driver of strategic change, the role of history in sense-making remains unexplored. Drawing on the concept of analogical reasoning, this chapter theorizes the connection between corporate archives and managerial sense-making, arguing that analogies drawn from past experience can reduce uncertainty and foster learning. This theory leads to the suggestion that consulting the corporate archive can promote strategic renewal and thus boost performance.

Abstract
The recent report for the Commission of the European Communities on current multilingual activities in the field of scientific and technical information and the 1977 conference on the same theme both included substantial sections on operational and experimental machine translation systems, and in its Plan of action the Commission announced its intention to introduce an operational machine translation system into its departments and to support research projects on machine translation. This revival of interest in machine translation may well have surprised many who have tended in recent years to dismiss it as one of the ‘great failures’ of scientific research. What has changed? What grounds are there now for optimism about machine translation? Or is it still a ‘utopian dream’ ? The aim of this review is to give a general picture of present activities which may help readers to reach their own conclusions. After a sketch of the historical background and general aims (section I), it describes operational and experimental machine translation systems of recent years (section II), it continues with descriptions of interactive (man‐machine) systems and machine‐assisted translation (section III), (and it concludes with a general survey of present problems and future possibilities section IV).

Abstract
Pictures are routinely identified as possible sources for researching history yet they are widely either neglected or underused. This article explores the use of pictorial materials, in particular photographs, in historical analysis. It describes some common, or standard, uses of photographs in historical writing, and critically discusses them. It identifies and examines methodological and ethical issues in using photographs as evidence. And it draws on a current project which is using a rich body of photographs as an integral part of its analysis of the history of one educational institution to explore these issues
