The present research aimed to identify the motivations, needs, wants, preferences and limitations of corporate professionals with regard to business social analytics.

Online interviews were conducted with 26 professionals the majority of whom work at the management level at 20 reputable corporations in Turkey. Both qualitative and quantitative data was collected during these interviews, which lasted an average of one hour.

The findings shed light on the motivations of corporate professionals for monitoring social media and other digital media, their perceived capability and limitations in doing so, the media that they monitor and wanted to monitor if possible, their criteria and processes for working with service providers in the field of business social analytics, their needs which are not fully met by service providers, their suggestions on service improvement and their reflections on how internal and external customer data can be analyzed with an integrated approach.

This research is an attempt to bridge the gap between the priorities of engineers who generate artificial intelligence for the purposes of social listening and analytics and the end users, e.g. corporate communication professionals. Only by doing so, this field, which is getting more and more important as people spend more time online, will reach its full potential and benefit corporations by providing fruitful insight upon which strategic steps can be taken.

Following the success of the novel facility for the testing of aircraft tyre, wheel and brake units — the most advanced of its kind in the world — installed at the Birmingham factory of Dunlop Ltd in 1973, an order has been received for a similar equipment for use in a USSR research establishment in Moscow. Vickers Ltd will again be responsible for the design, installation and commissioning of the complete test facility, an important feature of which is a powerful and sophisticated electrical drive system designed and supplied by GEC Electrical Projects Ltd. This drive system incorporates a method of inertia simulation for which extensive patent protection has been granted in the UK and a broad, and which is now being considered for other applications.

IN the two years since the last Farnborough Air Show was held by the Society of British Aerospace Companies the aircraft industry has achieved an almost complete metamorphosis from the body blows in the form of major programme cancellations that almost felled it in 1965 to the very healthy position that it holds today.

THE wind tunnel, through the use of models, offers a convenient means of investigating the aerodynamic characteristics of various parts of the aeroplane, individually or as a unit, and results obtained in it are generally applicable, within the limits of engineering precision, for the purpose of estimating full‐scale performance. It is believed that the results of control surface tests on models may be taken to represent full‐scale conditions with approximately the same degree of precision.

THE earliest origins of the Trident may be said to lie as far back as 1944 when we made some preliminary studies of the ways in which the newly arrived turbojet engine could be exploited for civil use. Our first thoughts were that the high consumption of the early centrifugal engines would restrict their practical use to short and medium hauls, and we envisaged a three‐engined aircraft with tail booms and engines buried in the rear of a short fuselage somewhat on the lines of a scaled‐up Vampire, capable of carrying 20 passengers over stages up to 750 statute miles and operating from 3,500—4,000 ft. runways.

THE Avro 642 has been designed as both a twin‐engined and four‐engined model.

THE innumerable hazards which threaten the safety of an aircraft during normal operations can in general be resolved under three headings: mechanical failure—such as disintegration of a turbine blade; effect of external conditions—such as precipitation, icing or a gusting wind; and finally that popular omnibus term—pilot error. Any combination of these hazards can and does occur.

SINCE the original British patent for telescopic oleo‐pneumatic shock absorbers for aircraft landing gear was drawn up in 1915 by Vickers engineer T. S. Duncan — with his invention of the positive recoil damping principle — Weybridge has been in the forefront of landing gear development on all types of aircraft for over half a century. Today, as a member company of British Aircraft Corporation, the Weybridge resources in this field are unique to a prime aircraft manufacturer. The landing gear units for the VC10 and B.A.C. One‐Eleven airliner families and the supporting design, production and testing facilities at Weybridge are among the most advanced in the world.

CASTORING stability requires automatic return, after displacement, of the castoring wheel to the central position. A hinged wheel may be automatically stable under static conditions, but dynamically unstable, or vice versa. Dynamic stability may be defined as the condition in which the forces on the wheel in motion secure its return to the path of direction of motion.
