Abstract

Purpose

The purpose of this paper is to optimise the cost‐based performance of a tubular linear generator and to minimise cogging forces.

Design/methodology/approach

Optimisation of a tubular linear generator with longitudinal flux topology has been undertaken using a finite element method. The computational models used have been verified experimentally.

Findings

The use of an oversized stator linear generator design as opposed to an oversized translator design has the potential to increase the output electromotive force per unit material cost by 25 per cent for slotless iron core topologies and approximately 14 per cent for air core topologies. For cogging force minimisation, optimisation of the length of the stator core is an effective technique for both oversized stator and oversized translator constructions. Comparisons of magnet materials also indicate that the higher cost of rare earth magnets to ferrites is compensated by their superior specific performances.

Originality/value

In this paper, a broader range of design parameters than in previous investigations has been optimised for the slotless iron core and air core topologies. The result relating to cogging force reduction and cost savings (in particular) has the potential to make direct drive wave energy extraction a more competitive technology in terms of reliability and cost.

Abstract

Man has been seeking an ideal existence for a very long time. In this existence, justice, love, and peace are no longer words, but actual experiences. How ever, with the American preemptive invasion and occupation of Afghanistan and Iraq and the subsequent prisoner abuse, such an existence seems to be farther and farther away from reality. The purpose of this work is to stop this dangerous trend by promoting justice, love, and peace through a change of the paradigm that is inconsistent with justice, love, and peace. The strong paradigm that created the strong nation like the U.S. and the strong man like George W. Bush have been the culprit, rather than the contributor, of the above three universal ideals. Thus, rather than justice, love, and peace, the strong paradigm resulted in in justice, hatred, and violence. In order to remove these three and related evils, what the world needs in the beginning of the third millenium is the weak paradigm. Through the acceptance of the latter paradigm, the golden mean or middle paradigm can be formulated, which is a synergy of the weak and the strong paradigm. In order to understand properly the meaning of these paradigms, however, some digression appears necessary.

Abstract

Subject area

This case can be used in courses on strategic management for second year masters’ level management students (with a focus on strategic analysis of internet-based business models in India) and entrepreneurship (with a focus on business growth). The primary focus of the case is how an internet-based business model in the food industry took shape.

Study level/applicability

The case enumerates how strategic analysis can be performed to analyze the firm based on topics such as the analysis of the mission and vision of Holachef based on the Ashridge mission model, examining strategy with Mintzberg’s 5Ps of strategy, performing a PESTLE analysis of HolaChef, evaluating Holachef with Porter’s industry analysis, performing Value net analysis for Holachef, examining Holachef’s business with strategy group analysis, examining the roots of core competencies of Holachef and explaining Holachef’s resource and capabilities with the valuable, rare, inimitable, non-substitutable (VRIN) Framework.

Case overview

Saurabh Saxena and Anil Gelra co-founded Holachef, “a restaurant in cloud” in March 2014. In a city like Mumbai, there are many households where both partners work; this had led to difficulties for people finding time to prepare food at home. Holachef is an online delivery platform which aggregates chefs for home-like multiple cuisine preparation. Holachef’s vision is to satisfy the need for homemade healthy food. The three pillars of Holachef to provide such food are technology (orders are taken through a website, mobile application and phone calls), food (enlisted chefs on the website) and logistics. The food prepared by chefs is assembled at different distribution centres and routed to customers. The efficient logistics and storage system maintain the quality of food. These pillars help Holachef to serve customers with efficiency at affordable prices.

Expected learning outcomes

Performing strategic analysis from both an industrial organization theory and resource-based view (RBV) perspective with VRIN framework. This is in the context of online business models in a digitizing India. Entrepreneurial strategy concepts and challenges faced by entrepreneurs in an online business.

Abstract

Purpose

Nurses need to display organizational citizenship behavior (OCB) for taking care of patients; uninterrupted care to coronavirus disease 2019 (COVID-19) patients in a stressful situation may result in emotional exhaustion and it hinders nurses' exercise of OCB. One perceives support when positive exchanges with team leaders and members (LMX) and team and members (TMX) take place for the benefit of self and the unit and lead to a feeling of commitment to the work team; the exchange facilitates the discharge of OCB. The study aims to explore the mediation effect of team commitments on the relationship between these factors with OCB of nurses in handling COVID patients.

Design/methodology/approach

The cross-sectional exercise attempts to find the impact of emotional exhaustion, LMX and TMX on the OCB of the nurses and mediating effects of team commitments on OCB; correlation analysis and multiple regressions are in use for examining the relationships. The use of Sobel test and bootstrapping exercise confirm the mediation and consistency of mediation results on a larger sample.

Findings

The paper finds that LMX, TMX and team commitments significantly relate to OCB; emotional exhaustion negatively impacts OCB and team commitments fully mediate the relationship between emotional exhaustion and OCB and partially mediate the relation between LMX and TMX with OCB.

Originality/value

Tests demonstrate that team commitments can neutralize the effects of emotional exhaustion resulting from handling COVID-19 patients on OCB of the nurses and is an addition to organizational behavior literature. The study also presents a model that shows how positive LMX, TMX and resultant team commitments support generating OCB and offset the impact of emotional exhaustion. Theoretical and managerial implications, limitations and scope for further research discussed in the paper.

Abstract

Purpose

The paper aims to extend research which has sought to explain Britain's early success as an industrial power by identifying the influence of religious doctrine of the Dissenting Protestant churches on the development of accounting practices in the factory. The concern is not with specific accounting practices but with the social and moral environment which provided the incentives and permissions that encouraged late eighteenth century English industrialists to develop the practices that they used.

Design/methodology/approach

The paper draws on the highly influential writings of social theorists such Weber, Sombart and Tawney to identify the religious doctrines that both motivated and justified the rational, ideological business practices of prominent businessmen.

Findings

The rise of accounting as a powerful tool of control and discipline was significantly assisted by the teaching of the Dissenting Protestant churches on “calling”. Religious beliefs provided permissions, justifications and incentives which underpinned the entrepreneurial energies, opportunities and successes of the early industrialists. Accounting could be seen to assume almost the aura and nascent legitimacy of a religious practice, a means of sanctifying practices which were otherwise reviled by social elites.

Originality/value

Despite encouragement from accounting researchers for histories of accounting which give greater credence to the reflexivity between accounting and society, this has yet to find a significant presence amongst the searches for beginnings in cost accounting where economic and management factors remain the overwhelming focus. Religious beliefs are shown to have been especially influential in the adoption of accounting practices by early industrialists who were frequently members of the Dissenting Protestant churches.

Abstract

This article reviews the overall issue of sweatshop labour practices, with a particular focus on the apparel industry. Although sweatshop labour exists in the United States, the media focus in recent years has centred mainly on overseas manufacture. This article will review individual companies and the practices of which they have been accused. The issue of labour compensation will also be explored, as low wages is the target reason for many apparel manufacturers to source their production overseas. Appendices to this article include Foreign Labour Statistics, outlining foreign labour compensation as compared to that of the United States. This article will also review the focus of the White House Industry Partnership and United Students Against Sweatshops. Lastly, there is a detailed recommendation for suggested required information on all apparel products labelling, which would summarise the manufacturer's quality of labour practices on the garment label; thus providing the consumer with immediate information on the environment under which the item was manufactured.
