Abstract

Subject area

International Business, Ethics, International Legal Issues/Law, Environmental Management.

Study level/applicability

Upper-level undergraduates and graduate students. The case is appropriate for courses in International Law, Ethics, International Business and Strategy.

Case overview

This case is inspired by current ethical, legal, social and environmental issues that have plagued the multinational mining industry in frontier markets. The case focuses on a multitude of legal, ethical and strategic issues involving the multinational mining industry. This case describes a hypothetical assignment facing an operations manager at the fictional Minera, Inc. The assignment revolves around several dilemmas a manager must confront as he attempts to secure valuable mining licenses from the Mongolian Government while simultaneously attempting to harmonize seemingly detrimental operating practices with the organizations' stated beliefs. The case provides detailed background information on the social, economic and political climate in Mongolia, as well as the applicable laws, ethical frameworks and competitive market considerations facing multinational mining organizations.

Expected learning outcomes

This case will help students understand the complexity of international business in frontier markets; identify key international legal issues such as the foreign corrupt practices act; and recognize ethical issues and formulate economically, strategically, ethically and legally sound courses of action in complex environments.

Abstract

Purpose

Ultrasonic additive manufacturing (UAM) is a rapid prototyping process through which multiple thin layers of material are sequentially ultrasonically welded together to form a finished part. While previous research into the peak temperatures experienced during UAM have been documented, a thorough examination of the heating and cooling curves has not been conducted to date.

Design/methodology/approach

For this study, UAM weldments made from aluminum 3003‐H18 tapes with embedded Type‐K thermocouples were examined. Finite element modeling was used to compare the theoretical thermal diffusion rates during heating to the observed heating patterns. A model was used to calculate the effective thermal diffusivity of the UAM build on cooling based on the observed cooling curves and curve fitting analysis.

Findings

Embedded thermocouple data revealed simultaneous temperature increases throughout all interfaces of the UAM build directly beneath the sonotrode. Modeling of the heating curves revealed a delay of at least 0.5 seconds should have existed if heating of lower interfaces was a result of thermal diffusion alone. As this is not the case, it was concluded that ultrasonic energy is absorbed and converted to heat at every interface beneath the sonotrode. The calculated thermal diffusivity of the build on cooling was less than 1 percent of the reported values of bulk aluminum, suggesting that voids and oxides along interfaces throughout the build may be inhibiting thermal diffusion through thermal contact resistance across the interface.

Originality/value

This work systematically analyzed the thermal profiles that develop during the UAM process. The simultaneous heating phenomenon presented here has not been documented by other research programs. The findings presented here will enable future researchers to develop more accurate models of the UAM process, potentially leading to improved UAM bond quality.

Abstract

Purpose

The purpose of this paper is to develop an effective framework for implementing Lean strategies in small- and medium-sized enterprises (SMEs) in the Kurdistan Region of Iraq (KRI).

Design/methodology/approach

Based on the integration of LM tools and techniques with the Malcolm Baldrige National Quality Award (MBNQA) criteria a systematic Lean implementation framework for manufacturing SMEs has been proposed. The core values, drivers and tools of the proposed framework were further developed based on case studies in three SMEs in the KRI.

Findings

Proposed framework is able to provide a simple pathway for SMEs to systematically implement Lean techniques in seven functional areas in order to create Lean culture in the organisation. Business performance measurement in terms of profitability, customer satisfaction, employee’s satisfaction, competitiveness growth and ergonomic improvement is presented in favour of evaluating Lean outcomes appropriately. It also presents the experience of small firms in implementing Lean programmes to show that Lean is valid in SMEs.

Research limitations/implications

The framework concentrates only on the internal issues of the organisation, while external variables such as national culture and external support are excluded.

Practical implications

The framework assists improvements in SMEs that either initially attempt to start Lean journey or those that are at more advanced levels towards excellent-Lean manufacturing. The framework can also be used as a self-assessment model to determine the degree of Lean readiness.

Originality/value

To the best knowledge of the author, it is the first framework that integrates Lean techniques with MBNQA criteria to support Lean implementation in SMEs. It is also the first study regarding Lean-excellence in the KRI.

Abstract

The Westland Lynx helicopter is a particularly fine example of the use of advanced fan technology in modern aircraft applications. The firm of Airscrew Howden have come a long way from their original manufacture of the wooden ‘prop’ but they still continue to play a very essential part in all types of aircraft flying today; this takes the form of sophisticated fan designs to cover a wide variety of special air‐movement requirements that can arise in this sector.

Abstract

Purpose

Electrical properties of biological tissues are known to be sensitive to physiological and pathological conditions of living organisms. For instance, human breast cancer or liver tumor cells have a significantly higher electrical conductivity than a healthy tissue. The paper aims to the new recently developed magnetoacoustic tomography with magnetic induction (MAT-MI) which can be deployed for electrical conductivity imaging of low-conductivity objects. Solving a test problem by using an analytical method is a useful exercise to check the validity of the more complex numerical finite element models. Such test problems are discussed in Chapter 3. The detailed analysis of an electromagnetic induction in low-conductivity objects is very important for the next steps in the tomographic process of image reconstruction. Finally, the image reconstruction examples for object’s complex shapes’ have been analyzed. The Lorentz force divergence reconstruction has been achieved with the help of time reversal algorithm.

Design/methodology/approach

In given arrangements the magnetic field and eddy current vectors satisfy the Maxwell partial differential equations. Applying the separation of variables method analytical solutions are obtained for an infinitely long conducting cylindrical segment in transient magnetic field. A special case for such a configuration is an infinitely long cylinder with longitudinal crack. The analytical solutions are compared with those obtained by using numerical procedures. For complex shapes of the object, the MAT-MI images have been calculated with the help of the finite element method and time reversal algorithm.

Findings

The finite element model developed for a MAT-MI forward problem has been validated by analytical formulas. Based on such a confirmation, the MAT-MI complex model has been defined and solved. The conditions allowing successful MAT-MI image reconstruction have been provided taking into account different conductivity distribution. For given object’s parameters, the minimum number of measuring points allowing successful reconstruction has been determined.

Originality/value

A simple test example has been proposed for MAT-MI forward problem. Analytical closed-form solutions have been used to check the validity of the made in-house finite element software. More complex forward and inverse problems have been solved using the software.

Abstract

Purpose

The purpose of this paper is to emphasize on the need for a fair and just economic system to achieve sustainability.

Design/methodology/approach

Using systems thinking approach it shows that climate change, ecological degradation, population growth, poverty and the resource scarcity, the problems of failing financial markets and economic recession are all intertwined with the present economic system, which has been responsible for transgressing the balance of nature.

Findings

The paper shows that all the reforms or alternatives to the contemporary economic system proposed in the literature do not really address the root cause of all the problems, which is the built-in usurious system, made possible with the paper currency, in the economy that creates great injustices. The paper argues that solutions of science and technology to ecological problems are limited because of ecological shortsightedness and corporate greed.

Originality/value

The paper introduces the concept of “fair and just” economic system for sustainable development of humanity and suggests future directions for its realization.
