Abstract
IN this issue we publish a translation (by MR TIBOR HAAS, whom readers will remember as the author of the paper ‘Fatigue Tests and Aircraft Life Evaluation’ in our October 1955 issue) of a paper by a distinguished German specialist in the study of fatigue. DR ING. E. GASSNER. We feel that this is a contribution of considerable importance, backed as it is by nearly twenty years of experimental and analytical experience of fatigue problems. Sonic of the points have been voiced before in this country, but this paper brings together the reasons which have made fatigue such a serious factor of ignorance in aircraft design since the war.

Abstract
THIS Conference, the largest ever arranged on the subject of fatigue of metals, was sponsored by The Institution of Mechanical Engineers in co‐operation with The American Society of Mechanical Engineers. A follow‐up Conference of the A.S.M.E. was to be held in New York from November 28–30.

Abstract
THE method used at present in fatigue testing aircraft joints and components by applying cycles of constant stress amplitude of a magnitude considered to be the most damaging is based on the assumption that Miner's cumulative damage rule, Σ(n/N)&equals l, holds good. This rule is known to be true only under certain conditions which may not apply to those under which fatigue damage is accumulated in aircraft.

Abstract
INTEREST in the fatigue of cabins of transport aircraft has increased considerably in the last year or so. Fatigue tests on a complete aircraft, undertaken as part of the Comet accident investigation, gave indications that the fatigue life of pressure cabins could be more critical than had generally been supposed.

Abstract
In this paper we present some results of our exploratory research about Hungarian tender buyers activity and culture. We try to formulate some questions for future research. Hungarian bidding habits and behavior are not yet deeply researched. The goal of this pilot study is to take a snapshot of the Hungarian tendering processes from the point of view of the seller-buyer interaction. Content analysis has been chosen as the methodological framework because of its potential for examining not well structured, symbolic, mainly behavioral or qualitative data. The most important findings drawn from analysing 515 Hungarian calls for tender published in May and June 1996 are as follows: • ⊎buyers use a tendering process mainly if it is obligatory by law; • ⊎vernmental and institutional buyers represent more than 75 percent of bids; • ⊎prequalification tenders have a law rate; • ⊎projects are the most frequented objects of bids

Abstract
The purpose of this paper is to investigate the implementation of environmental management systems as well as the critical factors for adapting ISO 14001 in Greek industry. The results were compared to a similar research conducted by Arthur D. Little among USA companies, and proved that the Greek companies consider implementation of IS0 14001 as being significant for the company’s success, with the most important factors being improving an organization’s image, reducing cost and improving quality, and showing care of the environment.

Abstract
Purpose
The main aim of this paper is to prove that an Environmental Management System (EMS) can be a powerful tool for organizations to both improve their environmental performance, and enhance their business efficiency.
Design/methodology/approach
A case study methodology is used putting forth the “Implementation of an EMS system at Pioneer Building and Construction”, a registered company in the construction industry whose primary business activities relate to development and construction of projects on a contract basis.
Findings
The findings stated that by implementing an EMS, Pioneer obtained a 10 per cent cost reduction; an estimated $1.2 million now could be saved annually as the annual costs were $12 million – which more than offsets the costs sustained in the implementation of ISO 14001.
Practical implications
This paper validates that although the causes of environmental degradation are well known, the business logic for environmental improvement has been largely operational and technical. Few firms have incorporated sustainability into their strategic thinking. A sustainable business should use its unique position to develop and achieve sustainable production and sustainable consumption at the same time. A responsible and sustainable system of environmental management should start with pollution prevention then expand into control and environmental design. The practical implications of this paper are to assist small business to embark on their implementation of the EMS.
Originality/value
EMS relevant information specifically with regards to the building and construction industry within the small business sector has been observed in this paper which is very important for similar such organizations to get cracking on their implementation of an EMS which is valuable in terms of improving their efficiency as well as being a social obligation for the future generation and the economy.

Abstract
Over the last three quarters of a century, the discourse on economic and social policy has oscillated between two polar opposites: an interventionist approach and a free market-oriented one. The former led to the establishment of the Keynesian welfare state and was dominant in the post-war years, but the latter gained much ground beginning in the 1980s, forcing defenders of the welfare state to retreat into a more defensive position. In the wake of the ‘Great Recession’, however, these two visions are once again sustaining vigorous debates in the global public arena. Economists in their role as policy advisers and public intellectuals, in other words as ‘experts’, have participated actively in such debates; the gains made by (what its critics call) ‘neo-liberalism’ were due, in no small measure, to the growing prestige and influence of Austrian economics. The experts’ discourse tends to be a historical and arguments are often phrased in terms of supposedly ‘cutting edge’ theoretical and empirical advances.1 Yesterday's theories are judged obsolete and irrelevant. I argue that a more historically informed perspective can actually be more rewarding.

Abstract
Interest in the field of entrepreneurship has significantly increased among academics, practitioners and government officials in the past decade both in the USA and in Europe. The increased interest is reflected in the increased number of courses, majors and minors at colleges and universities throughout the world; the increased number of endowed chairs; the increased number of journals in the field; the increased coverage of the field by the media; and the increased interest in the provision of government support. In light of this significant increased interest, it is important to understand the state of research in the field in Europe in the last few years, the focus of this article.
