Abstract

A theory of pre‐bid building price forecasting accuracy is proposed, based on the heuristic bias framework and with reference to the common practice of basing building price forecasts on the price per square metre of floor area, termed here as Price Intensity (PI). The main prediction of the theory, that high PI contracts will be underestimated and low PI contracts will be overestimated, is tested by a re‐analysis of a set of Singapore data and in comparison with previous work.

Abstract

THE eleventh annual meeting of the Institute was for the first time held simultaneously in three centres—in New York City at Columbia University, in Detroit at Rackham Educational Memorial, and in Los Angeles at the University of Southern California—from January 25 to 29. The purpose of the three simultaneous meetings was to minimize travel by executives and engineers from important war jobs in the present emergency. The same programme was offered at all three centres, papers being sometimes presented by proxies—experts in the same field as far as possible. In spite of the fact that attendance was divided between three centres, there was splendid representation at each place and a wide range of subjects was covered in the many papers. Naturally these were restricted more to analysis, and technology and information as to the latest design or production features of current aircraft or engines was withheld. The same ban applied to striking developments in accessories, instruments and armaments. All papers had to be approved by the Army or Navy and to be read substantially as written. While off‐the‐record discussions were permitted, these discussions were not made public. In particular there was a ban on comparisons between foreign and American materials, equipment or methods. The formula for control of comparison performance stated that the manufacturer's smooth curve calibrations and performance figures might be quoted, but no Wright field performance figures or data could be revealed. In spite of such restrictions a tremendous amount of valuable technical information was presented to the assembled engineers.

Abstract

Explores judicial attitudes in professional negligence cases affecting liability for property investment advice. Focuses on the standard of work required to discharge the legal duty of care and on apparent contradictions in approach by the courts. Reviews a series of cases which are taken to exhibit traditional attitudes to professional liability and studies modern cases which are irreconcilable with those attitudes. Includes liability to third party mortgagors and to third party mortgagees in an analysis of the duty of care, and considers the implications of the perceived expansion of the advisor′s professional duties, which include potential conflicts of interest and the dichotomy between the standards current among professionally qualified and unqualified practitioners. Suggests that judicial attitudes are influential in shaping the practice of property investment advice, but that this intervention is fraught with difficulties as it creates uncertainty among professional advisors about the nature of the tasks undertaken.

Abstract

Purpose

To apply the theories of project management to the transformation of the British Expeditionary Force (BEF) from the colonial‐style army of 1914 into the victorious continental‐style armies of 1918.

Design/methodology/approach

The methodological approach examines ten elements in the transformation. They range from the resources required to the necessary governmental changes. Emphasis is given to analysing the application of the new technologies, the political and social changes needed for eventual success, and the learning achieved.

Findings

Transforming the BEF was not to be an easy process. Obviously, the German nation, allies and armies did all they could to thwart this transformation. The “total war” waged is the ultimate form of “competition”. Thus, difficult lessons of strategic management, people (both men and women) management, and resources utilisation had to be learned. Through the many innovations, the experience curve was climbed to achieve mastery over the German field army.

Originality/value

To turn the BEF from a force of 120,000 at the battle of Mons to nearly 2 million at the Armistice on the western front was a remarkable achievement. Despite the strains imposed by German military prowess, the many elements were combined successfully. Although applying warfare principles to company management has become popular in the past decade, this paper avoids coming to simplistic conclusions. Rather it presents the transformation as a case study and suggests linkages to modern project management practices though leaving it to the reader to consider how these might be best applied.

Abstract

COMING from the company which produced the famous range of “gull‐wing” fighters, something unconventional was to be expected from this new bomber. The lay‐out follows, in general, that adopted for the French multiplaces de combat; but the lines are more refined and the machine is of smaller overall dimensions than these. The main plane is set rather low on the fuselage, between the true low‐wing and the middle‐wing positions. It is of low aspect‐ratio, a very modern feature, and set unusually close to the tail unit. A point of particular note is to be found in the crew arrangement, which is similar to that of the Fokker T.5 [Aircraft Engineer‐ing, March, 1938, page 83] and several other new designs from various countries. The machine is to be commanded by the front‐gunner‐bomb‐aimer‐navigator, with the pilot as a subordinate member of the crew. This idea, which is reminiscent of the early days of warships, when the commander was a soldier and the captain a very inferior person, was used by the German Feldtfliegertruppen during the Great War and is being revived in the Royal Air Force and other services where N.C.O. pilots are being introduced in the majority.

Abstract

To some persons, private gardens, public parks, and farms appear to offer a safe way to preserve all of the plants and animals the environment needs. To people who ignore the need for conservation, the idea of paving and pruning and artificially laying out our land from coast to coast seems welcome. Wiser persons perceive that the destruction so imposed on nature would ultimately endanger our existence. The wilderness, with its wealth of animals and plants, holds a treasure from which we already extract the chemicals and genes we need for agricultural breeding, for industrial products, and for healing drugs. What to the layman may look like a disorderly swamp, or a dark forest, or an uninteresting prairie, actually encompasses complicated communities of vegetation and animals of all classes, communities that are held together in a stable balance by their interdependent components. Ecologists are identifying the key principles at work in these ecosystems of wetlands and drylands, forests and prairies. In their search for understanding of how life on our planet functions, they have called attention to the overriding need to preserve and protect the biological diversity that characterizes ecosystems. They have found instances in which short‐sighted human tampering has played havoc with subtle ecological balances. Too frequently entire species have vanished under man's onslaught. Sometimes such a disappearance is an indication that an entire ecosystem is out of balance.

Abstract

THE Bréguet 410 multiplace de combat is a twin‐engine sesquiplane recently completed by this firm. It is the latest of a series of all‐metal military types of which the Bréguet 27, known as the “Tout Acier” (described in AIRCRAFT ENGINEERING, Vol. I, July, 1929, p. 181, and Vol. II, September, 1930, pp. 219–222) was the prototype. Among the features in the 410 derived from preceding developments of this type of Bréguet design are the beam fuselage, the undercarriage, the incidence adjustment of the top wing and the single‐unit construction of the lower wing built up round a girder.
