Abstract
Purpose
The objective of this paper is to measure the differences in heat transfer properties of refined hydrocarbon distillate fractions that are commonly used as base oils in aluminium sheet cold rolling applications and assess if the heat transfer coefficient (HTC) values for these oils can be predicted from their compositions. The composition and physical properties of these fluids affect their tribological behaviour by influencing hydrodynamic lubrication, wear debris removal and cooling.
Design/methodology/approach
A purpose-built test rig was used to measure HTCs for a wide range of hydrocarbon solvents used as aluminium cold rolling oils. The results are expressed in the form of the HTCs relative to those of 14- to 16-carbon-chain-length normal paraffins. Measured HTC values were compared to values calculated from oil compositions and from the thermal conductivities of compounds representing different classes of typical oil components.
Findings
There were significant differences between the heat transfer properties of various hydrocarbon solvents, and these differences could be estimated from their content of normal and simple iso-paraffins and heavily branched and cyclic hydrocarbons. The HTC of hydrocarbon mixtures increases with the increasing content of n-paraffinic compounds.
Originality/value
This paper shows how one can estimate the relative HTCs of oils of known compositions, based on the relative thermal conductivities of model compounds. This is relevant to prediction of cooling properties of aluminium cold rolling base oils.

“The United States can't sit around in striped pants drinking pink gin,” the late Sen. Jacob Javits (R‐NY) once warned. “Washington should discard its long‐standing and misguided notion that aiding American business is somehow wrong.” Now, someone in the nation's capital is listening. Believe it or not, it is Vice President Dan Quayle.

Abstract
Aim of the present monograph is the economic analysis of the role of MNEs regarding globalisation and digital economy and in parallel there is a reference and examination of some legal aspects concerning MNEs, cyberspace and e‐commerce as the means of expression of the digital economy. The whole effort of the author is focused on the examination of various aspects of MNEs and their impact upon globalisation and vice versa and how and if we are moving towards a global digital economy.

Abstract
It's getting down to decision time. The U.S. Congress will soon vote on the proposed North American Free Trade Agreement (NAFTA). The October 1992 accord, hammered out after many months of intense negotiation, would eliminate nearly all tariffs and other trade barriers between the United States, Canada, and Mexico over the next 15 years. A mammoth free trade zone from Canada's Yukon Territory south to Mexico's Yucatan peninsula would form the world's largest and richest trading bloc—encompassing 360 million people and economies that annually produce $6.6 trillion in goods and services.

Abstract
Purpose
The purpose of this paper is to consider the value of management history as a contributor to the development of the theory and practice of management and, to the extent that it is necessary to absorb the past in order to understand the present and inform the future, consider what happens to the knowledge base when the surviving “contributions” to the knowledge base are partial and, indeed, erroneous.
Design/methodology/approach
The articles that constitute this special issue form the launching‐pad for this discussion, with the ideas presented here combined with previous research and commentaries on the issues raised.
Research limitations/implications
In The Life of Reason, Santayana said, “Those who cannot remember the past are condemned to repeat it”. Managers looking for the “next big thing”, without being able to incorporate it effectively into their experience, and the experience of those who are long gone, are condemned to repeat not just the past, but also the mistakes of the past. Accordingly, it is also critical for management scholars to both recognise and take advantage of earlier thinking and empirical work to inform their contemporary musings and research if they are to provide meaningful frameworks for practitioners.
Originality/value
Drawing on the themes presented in the articles of this special issue, the paper demonstrates the value of knowing accurately the history of management thought to scholars and practitioners alike.

Abstract
A NEW metal finishing plant of advanced design has been installed by United and General Engineering (Victoria) Co. Ltd., at the David Brown subsidiary of Harrison, McGregor and Guest Ltd., of Leigh, Lancashire, where farm implements and sheet metal assemblies of David Brown tractors are made. Its installation has obviated a production bottleneck—existing paint plant facilities were inadequate for rising output—and has been designed to cope with increases in production up to 100%.

Abstract
This chapter proposes that corporate lawyers be studied as committed to their clients, asking how they advance exercises of power by those whom they have chosen to represent. Currently, corporate lawyers are studied as independent from their clients, asking how they resist client demands. Such research continues despite repeated findings that corporate lawyers are not independent. This chapter explains the puzzling persistence of independence by cultural understandings of both professionalism and law. It recovers a submerged historic voice in which corporate lawyers are judged by their position in a network of relations. It argues that it was the organization of the corporate law firm as a factory which allowed it to become a professional ideal. Market competition has led corporate law firms to move away from a factory model to one in which commitment to clients, not independence from them, is the organizing principle.
