Abstract
In this study, a power law process (PLP) for the failures of an engine, regarded as a complex repairable system, in a minimal repair set‐up (i.e. only a small proportion of the constituent parts of the engine are replaced on repair) with the engine regularly replaced within period T or replaced at the Nth failure after its installation, whichever occurs first, was examined. First of all, the Laplace test was used to check for the existence of a deteriorating trend in the failure data. Second, model parameters of the PLP were estimated using the maximum‐likelihood estimation method. Third, the Cramer‐von Mises test was used to test its goodness of fit. Finally, the optimal replacement policy based on minimising the long‐run expected cost per month for each type of engine was determined. The statistical inference procedure involving the maximum‐likelihood method for the PLP is based on the associated large‐sample theory. This implies the need to have a lot of data before conducting a statistical analysis. Unfortunately, the authors do not have sufficient data to conduct a real statistical analysis and to bring a significant conclusion to the considered application. The paper describes an industrial application of a PLP and a theoretical replacement model.

Abstract
Presents over sixty abstracts summarising the 1999 Employment Research Unit annual conference held at the University of Cardiff. Explores the multiple impacts of globalization on work and employment in contemporary organizations. Covers the human resource management implications of organizational responses to globalization. Examines the theoretical, methodological, empirical and comparative issues pertaining to competitiveness and the management of human resources, the impact of organisational strategies and international production on the workplace, the organization of labour markets, human resource development, cultural change in organisations, trade union responses, and trans‐national corporations. Cites many case studies showing how globalization has brought a lot of opportunities together with much change both to the employee and the employer. Considers the threats to existing cultures, structures and systems.

Abstract
Purpose
In 1990, the Americans with Disabilities Act (ADA) was signed into law by President George H.W. Bush. This law was intended to prevent discrimination against people with disabilities (PWD) in employment, public accommodations, transportation and other areas of life. However, the degree of impact in these sectors has not been studied in tandem. Addressing these sectors together is the primary objective of this paper.
Design/methodology/approach
Results are analyzed and presented regarding ADA impacts as well as which organizations provide advocacy services in support to PWD from survey data collected from 1,582 US participants in 2010 (N = 866) and 2015 (N = 716).
Findings
Results suggest that the ADA has had a positive impact on PWD, yet this law favorably affects people of certain demographics more than others. Moreover, people with and without disabilities have differing opinions on the impact of the ADA, suggesting that what is conveyed to the public and the impact of the ADA on real-life outcomes of PWD are sometimes misaligned.
Originality/value
The present study helps add to the current body of knowledge on the impact of the ADA by providing perspectives on advocacy services and impacts from a diverse set of PWD and their counterparts without disabilities.

This research aims to examine the relations between Shariah compliance and earnings quality.
Abstract
Purpose
This research aims to examine the relations between Shariah compliance and earnings quality.
Design/methodology/approach
The authors study three Shariah features: Shariah compliance status, level of Shariah compliance (H-Score) and Shariah compliance persistence. The sample consists of 463 firms from the Middle East and North Africa from 2011 to 2018. A variable determining the level of Shariah compliance was created in accordance with the methodology of S&P 500 Shariah and its underlying index, S&P 500. Then, a probate relapse study was created to identify the link between Shariah compliance and earnings quality.
Findings
Results show that Shariah-compliant firms engage in lower earnings management compared to their Shariah-non-compliant counterparts. This paper reveals that Shariah compliance status and high level of Shariah compliance have significant positive association with earnings quality. The authors also find novel evidence that persistence of the Shariah-compliant status has a significant negative association with earnings quality.
Practical implications
This study only examines firms listed on MENA stock markets. It is recommended to further study different markets in addition to the emerging Arab markets in order to compare and contrast the results. Further, larger sample observations from a greater date range can be used.
Originality/value
Few studies have examined the earnings management behavior of Shariah-compliant firms vs Shariah-non-compliant ones in emerging markets; however, no study has focused on Shariah-compliant firms and their level of Shariah compliance. To the best of our knowledge, this is the first study which uses all four proxies for earnings quality in association with Shariah compliance and used new Shariah variables such as Level of Shariah Compliance and Persistent Shariah Compliance status.

Abstract
The purpose of this chapter is to review how well walking interventions have increased and sustained walking, and to provide suggestions for improving future walking interventions. A scoping review was conducted of walking interventions for adults that emphasised walking as a primary intervention strategy and/or included a walking outcome measure. Interventions conducted at the individual, community, and policy levels between 1990 and 2015 were included, with greater emphasis on recent interventions. Walking tends to increase early in interventions and then gradually declines. Results suggest that increased walking, and environmental-change activities to support walking are more likely to be sustained when they are immediately followed by greater economic benefits/time-savings, social approval, and/or physical/emotional well-being. Adaptive interventions that adjust intervention procedures to match dynamically changing environmental circumstances also hold promise for sustaining increased walking. Interventions that incorporate automated technology, durable built environment changes, and civic engagement, may increase cost-efficiency. Variations in outcome measures, study duration, seasons, participant characteristics, and possible measurement reactivity preclude causal inferences about the differential effectiveness of specific intervention procedures for increasing and sustaining walking. This review synthesises the effects of diverse walking interventions on increasing and sustaining walking over a 25-year period. Suggestions are provided to guide future development of more effective, sustainable walking interventions at the population level.

Abstract
Organizational researchers studying well-being – as well as organizations themselves – often place much of the burden on employees to manage and preserve their own well-being. Missing from this discussion is how – from a human resources management (HRM) perspective – organizations and managers can directly and positively shape the well-being of their employees. The authors use this review to paint a picture of what organizations could be like if they valued people holistically and embraced the full experience of employees’ lives to promote well-being at work. In so doing, the authors tackle five challenges that managers may have to help their employees navigate, but to date have received more limited empirical and theoretical attention from an HRM perspective: (1) recovery at work; (2) women’s health; (3) concealable stigmas; (4) caregiving; and (5) coping with socio-environmental jolts. In each section, the authors highlight how past research has treated managerial or organizational support on these topics, and pave the way for where research needs to advance from an HRM perspective. The authors conclude with ideas for tackling these issues methodologically and analytically, highlighting ways to recruit and support more vulnerable samples that are encapsulated within these topics, as well as analytic approaches to study employee experiences more holistically. In sum, this review represents a call for organizations to now – more than ever – build thriving organizations.

Abstract
Looks at consumer research in Greater China including Mainland China, Hong Kong and Taiwan. Maps out the contributions within this area and guides future research. Examines the state of the art over the 1979‐97 period, with particular emphasis on the topics that have been researched, the extent of the theory development in the field and the methodologies used in conducting research. Uses content analysis to review 75 relevant articles. Suggests that, while a considerable breadth of topics have been researched, there remains much to be done, there is further room for theoretical development in Chinese consumer behaviour studies; and the methodologies used need improvement and further refinement.

Abstract
Purpose
The purpose of this study is to examine the impact of Confucianism on auditor changes by highlighting the role of the cultural embeddedness mechanism in audit contracts from the perspective of credit governance.
Design/methodology/approach
Using a unique sample of Chinese A-share listed firms from 2008 to 2018, this study uses logit regression as the baseline methodology while controlling for macro-level factors and firm-level characteristics, as well as industry and year fixed effects. This study also conducts different mediation/channel analyses, endogeneity tests (using two-stage least squares and difference-in-differences techniques) and robustness checks.
Findings
The findings show that the embeddedness of Confucianism in a corporation reduces auditor changes. Furthermore, the channel analyses (using moral self-discipline, social trust, professional ethics and the quality of accounting information as four potential channels) reveal that Confucianism can improve moral credit and consolidate the cultural foundation of credit governance. Specifically, the stronger the embeddedness of Confucianism, the more stable the auditing contract. Finally, Confucianism in formal and informal systems can be mutually substituted.
Originality/value
There is limited research on how culture affects auditing contracts. This study offers new contributions and extends the literature on the connection between cultural embeddedness and contract stability. Confucianism has the potential to strengthen the efficiency of credit governance and maintain the stability of contracts. This study offers a thoughtful orientation toward duly using Confucianism vis-à-vis credit governance.
