The purpose of this study is to provide a method for designing the software for a process control system that avoids difficulties that lead to safety problems.

Design of real-time software for safety critical programmable equipment systems (PES) such as process control or shutdown systems needs to be approached quite differently compared to any other software. It must be designed by those who understand the equipment system not by software engineers who do not. Following the ‘Piper Alpha’ disaster in the North Sea in the late 1980s, it was realised that the software of safety critical PES, such as the shut-down system on an oil rig, was proving very unreliable. Earlier hardwired relay-based shut-down systems were designed by process control engineers who understood the functions the equipment was required to perform; however, by the 1980s, such systems had been replaced by PES designed by system analysts who did not understand the technologies involved. The safety critical real-time software for a programmable equipment system will only be reliable when it is designed by control engineers who understand the functions it has to perform.

Bottom-up design of software is necessary to avoid safety issues and this can only be achieved using object-oriented methods.

This paper describes an entirely original idea of the author based on experience of managing the design and construction of the process control, emergency shut-down and fire and gas and communication systems for a major oil and gas platform in the North Sea around the time of the Piper Alpha disaster.

The purpose of this study is to examine factors contributing to family firms’ survival in the ongoing COVID-19 crisis; in this endeavour, the study espouses the underpinnings of social exchange theory and entrepreneurial resilience.

The views of 128 Italian family micro and small-sized firm owners/managers operating in different industries were gathered through an online questionnaire.

The analysis uncovers 12 fundamental factors contributing to firms’ survival; these are encapsulated in three dimensions and presented in two theoretical frameworks. The “beneficiary” dimension stresses the support from various internal and external stakeholders, while the “benefactor” dimension illustrates the commitment to extend the family tradition and be responsive to stakeholders. Finally, the “immersion/embeddedness” dimension denotes firms’ entrepreneurial behaviour, agility, decision-making and drive.

Firstly, and from a practitioner perspective, this study addresses recognised knowledge and research gaps in contemporary family business research, including how family firms are confronting the current unprecedented crisis. This response to current extant gaps provides first-hand empirical findings that could be primarily considered by industry stakeholders. Secondly, and from a theoretical angle, the aforementioned dimensions revealed through the analysis, coupled with the development of a theoretical framework, contribute to conceptual rigour and, therefore, a deeper understanding of family firms’ journey through an unprecedented event.

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).

Sheen Instruments report that although their range of gloss meters — particularly the pocket gloss meter — have again headed their sales during the past twelve months, with their equally extensive range of viscometers second, most new developments have been in coating thickness guages.

THE installation of a computer controlled manufacturing cell, based on a Fanuc Drill‐Mate machining centre, has doubled production capacity for key components at Mollart Universal Joints Ltd., Wokingham.

The days when a man's promotion prospects hinged on the say‐so of his boss may soon be over. A new management selection technique — imported from the US and already being tried out by several leading companies in Britain—gives a candidate just one day to carry out a series of make‐or‐break tests. Results are judged by specially trained assessors. Report by John Lawless.

WE write on the eve of an Annual Meeting of the Library Association. We expect many interesting things from it, for although it is not the first meeting under the new constitution, it is the first in which all the sections will be actively engaged. From a membership of eight hundred in 1927 we are, in 1930, within measurable distance of a membership of three thousand; and, although we have not reached that figure by a few hundreds—and those few will be the most difficult to obtain quickly—this is a really memorable achievement. There are certain necessary results of the Association's expansion. In the former days it was possible for every member, if he desired, to attend all the meetings; today parallel meetings are necessary in order to represent all interests, and members must make a selection amongst the good things offered. Large meetings are not entirely desirable; discussion of any effective sort is impossible in them; and the speakers are usually those who always speak, and who possess more nerve than the rest of us. This does not mean that they are not worth a hearing. Nevertheless, seeing that at least 1,000 will be at Cambridge, small sectional meetings in which no one who has anything to say need be afraid of saying it, are an ideal to which we are forced by the growth of our numbers.

At the turn of the twentieth century, various Socialist parties vied for a place in the American political system, making alliances where possible and convenient with elements of organized labor. Robert Franklin Hoxie, an economist at the University of Chicago whose principle contributions lay in his writings on the labor movement, wrote a series of essays in which he scrutinized the activities of the Socialist Party of America as it appeared to be at the time poised to become a viable force in American politics. This essay examines Hoxie’s writings on the conventions of the Socialist Party within the context of the political dynamic of the period and reveals his interpretations of events based on contemporary accounts and first-hand observations.
