SPACE shuttle missions, due to the critical nature of the operations and the variables that can affect them, require extraordinary precision in the shuttles themselves and in the payloads that they carry. Consequently, machining specifications for the vehicles and the payloads demand high tolerances.

Demonstrates the simple but effective application of a standard finite element program (PAFEC), and the associated geometric modelling code (PIGS), to the improvement of the design of an engineering component. The technique adopted involves augmenting material around zones of high stress and removing material in zones of low stress. This evolutionary procedure is related to the behaviour of bones in animals. The essentially two‐step procedure involves; finite element analysis of the preliminary component design using PAFEC; and, definition of a new geometry using PIGS, with selected stress contours giving an indication of the new shape. The technique, which proceeds iteratively, was first tested successfully on some classical academic optimisation problems. Its subsequent application to the industrial problem of a twin chamber pressurised extruded aluminium section, the primary component of an air drying system, resulted in material savings of up to 50 per cent and an associated drop in the maximum von Mises stress of 45 per cent. While this method does not determine the optimal structural form, it does generate substantial improvements in terms of material usage and reduced maximum stresses. It has the advantage that it can be used by any competent engineer with a working knowledge of the strength of materials, finite elements and structural form.

Quicker and cheaper manufacture of shims, gaskets, washers and other flat thin‐metal components is claimed for a new pressing process developed by Ford & Co. (South Shields) Ltd.

New contract shotblast facility Shotblast Derby Ltd., Delves Road, Heanor Gate Industrial Estate Heanor, Derbyshire, have just opened a new 12,000 sq. ft. factory for shotblasting and protective coatings.

IN a departure from usual practice this issue concentrates to a large extent upon a single subject — Mechanical Handling. It coincides with that industry's exhibition at Earls Court from the 9th to 19th of this month, to be opened by the Rt. Hon. Christopher Chataway, M.P., Minister for Industrial Development. In consequence it was necessary to defer some regular features for a time, for which we apologise.

The purpose of this paper is to begin to explore the strategic priorities of unicorn ventures as pursuers of market disruption. This study approaches this task by drawing on the positive deviance concept for studying outliers with the intent of understanding the strategic priorities of these ventures.

This is a comparison study of the priorities of 75 unicorn ventures, 37 early-stage ventures and 45 Fortune 500 organizations. The authors use computer-aided text analysis to conduct within-sample and between-sample means comparison tests of 12,487 newswires from 2022.

Where early-stage ventures emphasize their mission, and Fortune 500 companies emphasize financial results, unicorn ventures, occupy the middle of the spectrum, balancing their priorities between pursuing market disruption and achieving financial results. These high-growth outliers indicate their priorities by using significantly less positive tone, affective and prosocial language, and focusing less on corporate social responsibility initiatives, compared to early-stage ventures (and using more of this language compared to Fortune 500 ventures). An additional finding emphasizes that public Fortune 500 companies focus significantly more on money than their topic of interest.

This work has implications for understanding the strategic priorities of entrepreneurial ventures in different development stages. The results suggest that unicorn ventures actively work to balance their startup mission, which allows them to experience high-growth and achieve market disruption, with the financial demands of venture capital investors. This novel conclusion demonstrates the value of using positively deviant outlier cases, such as unicorn ventures, as a viable sample for studying market disruption.
