Abstract

Purpose

The purpose of this paper is threefold: to make explicitly clear the range of efficient multi‐objective optimization algorithms which are available with kriging; to demonstrate a previously uninvestigated algorithm on an electromagnetic design problem; and to identify algorithms particularly worthy of investigation in this field.

Design/methodology/approach

The paper concentrates exclusively on scalarizing multi‐objective optimization algorithms. By reviewing the range of selection criteria based on kriging models for single‐objective optimization along with the range of methods available for transforming a multi‐objective optimization problem to a single‐objective problem, the family of scalarizing multi‐objective optimization algorithms is made explicitly clear.

Findings

One of the proposed algorithms is demonstrated on the multi‐objective design of an electron gun. It is able to identify efficiently an approximation to the Pareto‐optimal front.

Research limitations/implications

The algorithms proposed are applicable to unconstrained problems only. One future development is to incorporate constraint‐handling techniques from single‐objective optimization into the scalarizing algorithms.

Originality/value

A family of algorithms, most of which have not been explored before in the literature, is proposed. Algorithms of particular potential (utilizing the most promising developments in single‐objective optimization) are identified.

Abstract

Purpose

The purpose of this paper is to propose a surrogate model‐assisted optimization algorithm which effectively searches for the optimum at the earliest opportunity, avoiding the need for a large initial experimental design, which may be wasteful.

Design/methodology/approach

The methodologies of two‐stage and one‐stage selection of points are combined for the first time. After creating a small experimental design, a one‐stage Kriging algorithm is used to search for the optimum for a fixed number of iterations. If it fails to locate the optimum, the points it samples are then used in lieu of a traditional experimental design to initialize a two‐stage algorithm.

Findings

The proposed approach was tested on a mathematical test function. It was found that the optimum could be located, without necessarily constructing an accurate surrogate model first. The algorithm performed well on an electromagnetic design problem, outperforming both a random search and a genetic algorithm, in significantly fewer iterations. The results suggest a new interpretation of surrogate models – merely as tools for constructing a utility function to locate the optimum of an unknown function, as opposed to actual approximations of the unknown function.

Research limitations/implications

The research was carried out on unconstrained problems only. The findings have implications for modern experimental designs, as the proposed algorithm can often locate the optimum without necessarily constructing an accurate surrogate model.

Originality/value

The two paradigms of one‐stage and two‐stage selection of points in surrogate‐model assisted optimization are combined for the first time. Also, it is believed that this is the first time that the methodology ofone‐stage optimization has been used in optimal electromagnetic design.

Abstract

Looks at the 2000 Employment Research Unit Annual Conference held at the University of Cardiff in Wales on 6/7 September 2000. Spotlights the 76 or so presentations within and shows that these are in many, differing, areas across management research from: retail finance; precarious jobs and decisions; methodological lessons from feminism; call centre experience and disability discrimination. These and all points east and west are covered and laid out in a simple, abstract style, including, where applicable, references, endnotes and bibliography in an easy‐to‐follow manner. Summarizes each paper and also gives conclusions where needed, in a comfortable modern format.

Abstract

Purpose

This paper describes the personal history and intellectual development of Morris B. Holbrook (MBH), a participant in the field of marketing academics in general and consumer research in particular.

Design/methodology/approach

The paper pursues an approach characterized by historical autoethnographic subjective personal introspection or HASPI.

Findings

The paper reports the personal history of MBH and – via HASPI – interprets various aspects of key participants and major themes that emerged over the course of his career.

Research limitations/implications

The main implication is that every scholar in the field of marketing pursues a different light, follows a unique path, plays by idiosyncratic rules, and deserves individual attention, consideration, and respect … like a cat that carries its own leash.

Originality/value

In the case of MBH, like (say) a jazz musician, whatever value he might have depends on his originality.

Abstract

A hobby is any purposeful use of leisure time. Due in part to an increase in the amount of leisure time available to most Americans, the hobby and recreation industries have grown by leaps and bounds in the past few years. There are countless publications on hobbies ranging from genealogy to doll collecting, from painting to needlepoint. Obviously, a compilation such as this cannot include publications on every imaginable hobby, so rather than appear biased, this author has attempted to include primarily publications that discuss many different hobbies, or deal with one major group of hobbies.

Abstract

Investigates the impact of retail customers’ attitudes towards local retail establishments and their impact on local retail trading behaviour. Heads of 206 households were interviewed by telephone in two separate Indiana towns, each located approximately 55 miles from a major metropolitan trading area. Findings indicate there is strong positive correlation between the attitudes of consumers and local economic performances. Poor attitudes of consumers towards local business resulted in a higher percentage of income spent outside the community, which may reduce the growth of local business and employment opportunity. The unemployment rate of the community with positive attitudes was 2.2 per cent compared to 7.5 per cent of the community with negative attitudes. Suggests that small businesses and local retailers should have a concept of competition and provide service and satisfaction to the customer, instead of sitting back and being complacent.

Abstract

Purpose

The purpose of this paper is to critically examine and reformulate T.H. Marshall's concept of industrial citizenship, and apply the reformulated model to a case study of the UK.

Design/methodology/approach

Marshall's conceptualisation of industrial citizenship is criticised for neglecting the rights of unions as collective rights and for treating industrial citizenship as an aggregation of individual rights. Subsequent attempts to use the idea of industrial citizenship are similarly flawed. A case study of changes to industrial citizenship in the UK in the 1980s and 1990s is used to develop the new model and provide evidence in support of it.

Findings

An alternative conceptualisation of industrial citizenship is presented that outlines collective and individual powers, obligations, liberties, constraints, immunities and liabilities. This model is illustrated using examples from the Conservative governments' industrial relations legislation of the 1980s and 1990s.

Originality/value

Discussions and applications of T.H. Marshall's concept of industrial citizenship are few and far between. The paper proposes an original re‐conceptualisation specifying the collective rights of unions in the British regime of industrial citizenship. This new concept of industrial citizenship is then applied to the radical changes in industrial relations legislation in the UK in the 1980s and 1990s.
