Abstract
Purpose
Manufacturing tolerances can result in an unwanted behavior of electrical machines. A quality control of machines subsequent to manufacturing is therefore required in order to test whether the machines comply with its specifications. This paper aims to describe the consideration of rotor tolerances due to non-ideal manufacturing processes.
Design/methodology/approach
Various fault scenarios are studied employing numerical field simulations focusing the influence of rotor tolerances on current and back-EMF of the studied machine.
Findings
This analysis shows that electrical quantities are applicable to realize tolerance diagnosis by evaluating the influence of non-ideal manufactured rotor components on the back-EMF and current characteristics of the studied machine.
Practical implications
This study provides an approach how to estimate the influence of the manufacturing tolerances for realization of a reliable quality control. This is useful to ensure a high reliability of the manufactured machines.
Originality/value
This paper gives a close insight on how to investigate non-ideal manufacturing and in particular its influence on the stator current.

Abstract
The ability for learners to interact online via their avatars in a 3-D simulation space means that virtual worlds afford a host of educational opportunities not offered by other learning technology platforms, but their use also raises several pertinent issues that warrant consideration. This chapter reviews the educational use of virtual worlds from a design perspective. Virtual-world definitions are explored, along with their key educational characteristics. Different virtual-world environments are briefly contrasted, including Second Life, Active Worlds, Open Sim, and Minecraft. A wide variety of virtual-world uses in schools and universities are examined so as to understand their versatility. Key educational benefits of virtual worlds are distilled from the literature, such as the ability to facilitate 3-D simulations, role-plays, construction tasks, and immersive learning. Emergent issues surrounding the use of virtual worlds are also analyzed, including cognitive load, safety, and representational fidelity. One higher education and one school level vignette are provided in order to offer more detailed insight into the use of virtual worlds in practice. Recommendations for learning design and implementation are presented, based on the thematic analysis of contemporary virtual-worlds research.

Abstract
It has generally been assumed that effective leadership is a key to successful change. But, as some authors have noted, there is a dearth of empirical research regarding the impact of leadership on organization change. In this chapter, we review the empirical evidence from the past 20 years in an attempt to determine the impact of leadership on the conduct and outcomes of organizational change. Our conclusions indicate that the leadership of change is more complex than envisioned, involving multiple forms of leadership engaged in different approaches, behaviors, and activities, only some of which are effective.

Abstract
Measures of change are used for two main purposes in OD: (a) estimating the amount of change that occurred from an OD intervention (e.g. mean differences); and/or (b) assessing relationships between two or more variables as part of hypothesis testing (e.g. correlations). In this study we primarily focus on the hypothesis testing purpose for measuring change, although we will discuss the implications for estimating the amount of change.
We focus on two alternative measures of the change in job satisfaction over time: (a) Longitudinal Change; and (b) Remembered Change. These two measures of change are used as predictors of organizational commitment and the number of labor grievances filed by individuals. Our results show that combining both measures of job satisfaction change together explains more variance than either measure alone. We conclude by discussing the meaning of change and the implications of these results for both OD practice and research.

Abstract
Purpose
This study aims to examine the effect of perceived supervisor support (PSS) and workplace dignity (WPD) on employees' affective commitment to change (ACC). It also investigates PSS as an antecedent of WPD and WPD as a mediator between PSS and ACC.
Design/methodology/approach
To examine the proposed relationships, data was collected from employees of an Indian public sector company undergoing many change initiatives at the time of the study. The hypotheses were tested using the structural equation model.
Findings
The findings indicate the direct effect of PSS and WPD on employees' ACC, and WPD does mediate between PSS and ACC. The results also suggest PSS works as an antecedent of WPD.
Practical implications
The findings suggest how organizations can enhance employees’ ACC by creating a positive context involving supervisor support and experience of WPD.
Originality/value
The findings contribute to ACC literature by highlighting the role of WPD and PSS. This is one of the few quantitative studies which examines the antecedent and consequences of WPD.

Abstract
Purpose
The purpose of this paper is to explore the relationship between transformational leadership and voice during the change-planning process. The authors propose a moderated mediation model to investigate the relationship between voice, other change-related variables, and the boundary conditions of transformational leadership.
Design/methodology/approach
The authors collected survey data from 124 employees and their leaders in a medical technology company in Norway. The organization was planning a major restructuring of its working procedures. The authors analyzed the data using PROCESS and a fixed effect approach.
Findings
The results suggest that transformational leadership has no effect on change-related voice (CRV) by itself. However, there is an indirect effect through affective commitment to change. This effect is conditional on the employees’ level of perceived change impact.
Research limitations/implications
The paper is limited by the cross-sectional design of the study. Other potential limitations are discussed.
Originality/value
The paper is the first to explore the relationship between transformational leadership and CRV, and is thus interesting for practitioners who wish to increase the level of CRV from their employees. Furthermore, researchers interested in organizational change and proactivity constructs such as voice will also find the paper valuable.

Abstract
This paper synthesizes the extant feedback literature, focusing on how feedback affects an auditor’s learning, performance, and motivation. Performance feedback is an important component in the auditing environment for ensuring quality control and for developing and coaching staff auditors. However, the literature on feedback in the audit environment is fragmented and limited making it difficult to assess its behavioral effects on auditors. This paper has three main objectives. The first is to review some of the influential research in psychology and management to identify key variables and issues that appear to be critical in the study of behavioral consequences of feedback in organizational settings. The second is to review performance feedback research specifically in auditing to identify the areas previously examined and synthesize the findings. The third is to suggest a variety of future research opportunities that may assist in developing an understanding and knowledge of the behavioral effects of feedback on auditors. The literature analysis has significant implications for audit research and practice. In particular, the analysis provides important insights into understanding who, how, and when performance feedback should be given to improve its effectiveness in the audit environment.

Abstract
Purpose
The purpose of this article is to study how we may identify the link between rising externality costs and corporate social responsibility (CSR) by using a market‐centric approach to CSR.
Design/methodology/approach
The paper uses indicators measuring CSR performances triggered by rising externality costs due to EU legislation on electric and electronic equipment (EEE). The case study includes three leading companies in the global electric appliances industry.
Findings
The EU legislation on EEE has increased the externality costs of the electric appliances industry. Some companies only meet the minimum requirements of the legislation, while others go beyond what is required and engage in CSR. It is found that the strongest CSR impact is related to output externalities in the authors' sample in the EEE sector, while the strongest CSR impact in the clothing sector, in an earlier study, is related to input externalities.
Practical implications
The findings suggest that governments need to adapt their CSR policies not only to general sector‐specific features, but in addition to the potential for reducing negative externalities in different parts of the value chain in each sector.
Originality/value
This article contributes to a better understanding of how government policies raise the externality costs of industries, which in turn lead these industries to strengthen their CSR performance. The study also demonstrates the usefulness of a market centric approach to CSR.
