Abstract

This paper describes a multistrategy knowledge‐based framework for supporting human experts in assessing applications for the house renovation grant system (HRGS). This framework integrates different problem solving strategies as set up by the task analysis. The task analysis carried out in the context of the HRGS domain decomposed the overall task into a number of subtasks and problem solving methods for performing each subtask. The framework modularises the knowledge required to solve each subtask into historical cases, objects, procedures and domain models. The framework was implemented as a computer system using Kappa‐PC which is a shell designed for implementing knowledge‐based systems. The implementation followed the client centred approach (CCA) method. This computer application has been successful in demonstrating that a multistrategy knowledge base can be used to support human experts in assessing applications for the HRGS. Therefore, the application has proved to perform as accurately as human experts do for all of the subtasks set up by the task analysis.

Abstract

This is a comparative case study of how three high school history teachers in the U.S.A. use art in their practice. The following research question was investigated: How do secondary history teachers incorporate the arts—paintings, music, poems, novels, and films—in their teaching of history and why? Data were collected from three sources: interviews, observations, and classroom materials. Grounded theory was utilized to analyze the data. Findings suggest these teachers use the arts as historical evidence roughly for three purposes: First, to teach the spirit of an age; second, to teach the history of ordinary people invisible in official historical records; and third, to teach, both with and without art, the process of writing history. Two of the three teachers, however, failed to teach historical thinking skills through art.

Abstract

Purpose

The purpose of this paper is to present an approach to address the overfitting and collinearity problems that frequently occur in predictive cost estimating models for construction practice. A case study, modeling the cost of preliminaries is proposed to test the robustness of this approach.

Design/methodology/approach

A hybrid approach is developed based on the Akaike information criterion (AIC) and principal component regression (PCR). Cost information for a sample of 204 UK school building projects is collected involving elemental items, contingencies (risk) and the contractors’ preliminaries. An application to estimate the cost of preliminaries for construction projects demonstrates the method and tests its effectiveness in comparison with such competing models as: alternative regression models, three artificial neural network data mining techniques, case-based reasoning and support vector machines.

Findings

The experimental results show that the AIC–PCR approach provides a good predictive accuracy compared with the alternatives used, and is a promising alternative to avoid overfitting and collinearity.

Originality/value

This is the first time an approach integrating the AIC and PCR has been developed to offer an improvement on existing methods for estimating construction project Preliminaries. The hybrid approach not only reduces the risk of overfitting and collinearity, but also results in better predictability compared with the commonly used stepwise regression.

Abstract

This chapter covers three main concepts: it provides an overview of supply chain management (SCM), introduces the concepts of procurement and what is entailed within this function, and explains how inventory is managed. In the first section, SCM is considered broadly but also in the context of hospitality. The key roles and objectives of SCM as well as the significance of supply chain risk and disruption are considered. In the second section, the concept of sourcing is discussed. Sourcing is a critical function in any organization: without this, an organization would cease to operate. The importance of supplier selection is explored, with methods to make the most appropriate selection and for subsequently managing suppliers. Finally, the third section focuses on how inventory management can be optimized. Concepts such as economic order quantity (EOQ) and ABC analysis are explored, along with alternatives to traditional inventory management methods.

Abstract

This article examines the value of the concept of significant harm some 20 years after its introduction in the Children Act 1989. It introduces the concept of significant harm and then discusses the profile of children and families in care proceedings, the decision‐making process, the interpretation of significant harm in case law, ‘panic’ and its impact on patterns of referrals for case proceedings, and the issue of resources. An alternative model of the problem‐solving court is outlined. It is suggested that ‘significant harm’ has largely stood the test of time. However, the absence of a clear operational definition is both its strength and its weakness. It allows necessary professional discretion but is vulnerable to external pressures affecting its interpretation. A more confident workforce and sufficient resources are required, but the future role of the court and compulsory care is more contentious. The problem‐solving court model may offer a helpful way forward for the scrutiny of significant harm.

Abstract

Purpose

This article aims to focus on the role of lived‐experience in mental health education and practice as perceived by undergraduate students.

Design/methodology/approach

A small qualitative survey was conducted among Social Work and Mental Health Nursing students who were asked about their own experiences of mental ill health and its possible impact on their practice.

Findings

The article is contextualised in the concept of “Wounded Healers” as a number of students had previously (and were currently) experiencing mental distress.

Originality/value

There is a strong sense that students believe that their personal experiences inform their practice, and that this may assist them in empathising constructively with service users, within the boundaries of a professional relationship.

Abstract

Purpose

In view of the existing void in the current international and cross‐national/cultural marketing literature, the purpose of this paper is to look into the similarities and differences of life‐style orientations prevalent among US and Canadian consumers. The AIO (Activities, Interest, and Opinions) and VALS (Values, Attitudes, and Life‐Styles) statements adapted from the current cross‐cultural marketing literature were utilized to determine different US and Canadian consumer market segments. The research tools and techniques used in this study help retail businesses as well as manufacturing companies of the two countries to develop and execute more effective target marketing strategies.

Design/methodology/approach

The data for this study were collected through self‐administered questionnaires. The questionnaires were administered in two different locations. First, in Brandon, Canada and second, in the rural part of south central Pennsylvania (York and Lancaster counties). Both regions are similar to each other, each having a flourishing agricultural industry and a significant number of companies in the service and manufacturing industries. The data were collected through a drop‐off and pick‐up method among a sample of 300 Canadian married or common‐law families and 400 in the USA.

Findings

The study results show that there are, indeed, differences among the consumers’ life‐styles in the two countries which were similar in demographics and as such may have been previously treated the same way by marketers, but in reality have very different lifestyles. Based on the survey findings, managerial and/or public policy implications are offered for orderly marketing decision‐making purposes.

Research limitations/implications

A study of total urban consumers may produce different life‐style profiles than the ones presented here. This study only examined North American consumer life‐styles within the framework of product group (form). Additional studies may look at consumer life‐styles by use of product brands and even product options.

Originality/value

This empirical research study presents cross‐cultural comparisons of life‐styles, value orientations of consumers in the purchase of a variety of goods and services in the similar environments of North America, namely rural areas of the USA and Canada.

Abstract

Dispersed multinational teams include people from multiple nations, some of whom are not collocated. In a knowledge economy, such teams must locate, store, allocate, and retrieve knowledge. Three central questions are: (a) How can dispersed multinational teams manage knowledge resource flows? (b) What factors influence knowledge resource distribution in these teams? and (c) How do dispersed multinational teams evolve over time? This chapter examines knowledge resource sharing in multinational teams through three theoretical lenses: transactive memory theory, collective action theory, and evolutionary theory, and concludes with practical suggestions for managing dispersed multinational teams that are derived from these three theoretical lenses.
