It is all too easy in the hectic world of business to get too involved with the day‐to‐day managing of processes and events. When this happens it is difficult to see the wood for the trees and the automatic pilot syndrome takes over. This does not suggest that you do not know what you are doing ‐ on the contrary you are probably as switched on to whatever activity you are managing as anyone could be. What you could be missing, however, is the explanation as to why you are doing it. If this sounds familiar to you, what might be needed is a detached period from your work. By this I mean stay on the high ground for a while so you can get an overview of what you are doing and, more importantly, why you are doing it. How many managers, I wonder, get the opportunity to question what they are doing? If you allow yourself to slip into complacency then you and your organization will soon lose competitive advantage.

Allyn Young′s lectures, as recorded by the young Nicholas Kaldor, survey the historical roots of the subject from Aristotle through to the modern neo‐classical writers. The focus throughout is on the conditions making for economic progress, with stress on the institutional developments that extend and are extended by the size of the market. Organisational changes that promote the division of labour and specialisation within and between firms and industries, and which promote competition and mobility, are seen as the vital factors in growth. In the absence of new markets, inventions as such play only a minor role. The economic system is an inter‐related whole, or a living “organon”. It is from this perspective that micro‐economic relations are analysed, and this helps expose certain fallacies of composition associated with the marginal productivity theory of production and distribution. Factors are paid not because they are productive but because they are scarce. Likewise he shows why Marshallian supply and demand schedules, based on the “one thing at a time” approach, cannot adequately describe the dynamic growth properties of the system. Supply and demand cannot be simply integrated to arrive at a picture of the whole economy. These notes are complemented by eleven articles in the Encyclopaedia Britannica which were published shortly after Young′s sudden death in 1929.

Presents a simulation model for studying the availability of an iron‐ore production plant interconnected logistically with a large Integrated Steel Manufacturing System (ISMS). The objective of the simulation experiment is to validate whether there exists adequate capability of the existing iron‐ore production plant to meet the demands of the hot metal production plant of ISMS. Availability estimation has been made for the total unit of the iron ore production plant and sensitivity tests have been carried out with respect to buffer storages in between workstations. The model has been applied to a real‐life large ISMS in India and the results have been implemented also by the management of the company.

Preface The functions of business divide into several areas and the general focus of this book is on one of the most important although least understood of these—DISTRIBUTION. The particular focus is on reviewing current practice in distribution costing and on attempting to push the frontiers back a little by suggesting some new approaches to overcome previously defined shortcomings.

“It should also be noted that the objective of convergence and equal distribution, including across under-performing areas, can hinder efforts to generate growth. Contrariwise, the objective of competitiveness can exacerbate regional and social inequalities, by targeting efforts on zones of excellence where projects achieve greater returns (dynamic major cities, higher levels of general education, the most advanced projects, infrastructures with the heaviest traffic, and so on). If cohesion policy and the Lisbon Strategy come into conflict, it must be borne in mind that the former, for the moment, is founded on a rather more solid legal foundation than the latter” European Commission (2005, p. 9)Adaptation of Cohesion Policy to the Enlarged Europe and the Lisbon and Gothenburg Objectives.

THROUGHOUT history certain decades emerge which are of cardinal import to mankind, like the one beginning in 1781, when the inventions of fifty years reached their apogee and through general application transformed the prevailing cottage industry into what we now call the factory system. That vast accretion of resources changed the human environment.

Recently the route connecting the trans-Korean railway and the trans-Siberian railway has become of particular interest for many academics and policy-makers in East Asian countries. The extensive review of previous studies, however, reveals that literature on the subject is lacking solid analytical framework. Most studies are one-sided, focusing on the political aspects of the issue or paying little attention to the economic aspects of the problem.

This study intends to develop an analytical framework through which the most efficient route among four major alternative routes connecting the trans-Korean and trans-Siberian railways can be identified. It attempts to assign priorities to the four alternative routes according to their level of economic efficiency.

This study utilizes a simple cost-benefit analysis in evaluating the four routes. Cost side, transportation time, effectiveness of customs procedures, and gauge difference are selected as the main economic factors. The volume of cargo, industrial production in adjacent regions, access to natural resources, and market size and foreign investment climate are used to evaluate the benefits of the routes.

The study concludes that Route 3, which connects ‘Busan - Seoul (South Korea) –Pyongyang -Sinuiju (North Korea) –Shenyang –Beijing - Erenhot (China) –Ulaanbaatar (Mongolia) –Ulan-Ude - Moscow (Russia)’ is the most efficient route.

The purpose of this paper is to measure and evaluate the efficiency of materials management in the European Union countries (EU-28) during the period of 2008–2017.

The study was conducted using the method of data envelopment analysis (DEA) and variables applied to determine the resource productivity indicator. Therefore, the components of domestic material consumption constituted inputs in the DEA method, while gross domestic product (GDP) was applied as an output.

The results of the analysis showed that the Netherlands, Luxembourg, Latvia and the UK are the efficiency leaders among all the member states of the European Union. One of the least efficient countries is Poland, which uses too much natural resources in the process of generating goods and services. However, this consumption is growing at a slower rate than the value of GDP, which is beneficial from the point of view of sustainable development. Poland, like other inefficient countries, should reduce its consumption of natural resources in line with the best international practices.

The obtained research results can be a valuable source of information for decision-makers, and contribute to the adoption of more effective policies in order to improve the relationship between materials consumption and economic growth.

The application of the DEA method for calculating the efficiency of materials management represents a new approach, and it is the first attempt of its kind in the European Union countries.

This paper aims to produce iron ore tailings reinforced polypropylene composites (ITR-PPCs) from conventional compo-casting (CC) and a proposed compo-indirect squeeze casting (C-ISC) processes. It intends to quantify the compressive behaviour of ITR-PPC with respect to production process, iron ore tailings volume and particle size inclusion in polypropylene (PP) through controlled material and compressive testing. The study aims to provide useful information on possibility of the use of ITR-PP for compressive applications which will culminate to judicious use of iron ore tailings that is been piled up as waste material at the iron ore beneficiation sites.

ITR-PPC compression specimens were produced using C-ISC and CC processes. Prior to production, the iron ore tailings was dried at room temperature according to ASTM 618, ASTM 171 and ASTM E 41. The different particle sizes were generated using standard laboratory sieves. Uniaxial compressive test procedure according to ASTM D 695 was carried out on ITR-PPC compression specimens with length/diameter ratio equal to 2.0 under standard laboratory atmosphere on an Instrom 3,369 machine.

It was discovered that pure PP produced using the C-ISC process exhibited better compressive strength and Young’s modulus of about 12 and 4.5 per cent, respectively, while a reduction of 9.2 per cent in yield strength was recorded. ITR-PPCs with 150-μm fillers produced from C-ISC process have lower yield stress, compressive strength and Young’s modulus at volume contents above 10 per cent. It also exhibited lower strain at fracture at volume content above 15 per cent, while composites filled with 212- and 300-μm particle size iron ore tailings using the C-ISC process had better strain at fracture.

The present work cannot ascertain the compressive behaviour of ITR-PPC produced from other production processes, hence the need for further work in this area.

The paper provides an avenue to address the pollutant effect of iron ore tailings by putting it to judicious use through addition as fillers in plastics. It also removes the need for expensive and repeated experimentation to determine the compressive behaviour of ITR-PPCs.

This paper has brought to fore the need to study iron ore tailings as filler in plastics and other material matrices.
