Abstract
Purpose
With the emergence of COVID-19 and increased infections, organizations urged their employees to work from home. Furthermore, with the on-going pandemic, employees take measures to ensure individual safety and their families. Hence, work from home culture can result in long-term employee satisfaction. However, no study addresses the development of work from the home culture in an integrated framework. Therefore, the current research explores the role of safety during the pandemic, organizational commitment and employee motivation on work from home culture, which may influence employee satisfaction. Furthermore, job demands and home demands were also evaluated for employee satisfaction.
Design/methodology/approach
The study used existing scales of the factors to develop the measures and collect perceptual responses from employees working from home, supported with a pre-test. The study executed a survey with effective responses from 132 individuals spread across different sectors to validate the hypotheses. The responses were analysed using partial least squares in ADANCO 2.2.
Findings
Findings suggest safety concerns along with organization commitment enhances work from home culture. Such work from home culture enhances employee motivation and employee satisfaction. Furthermore, job demands and home demands also influence employee satisfaction.
Originality/value
To the best of the authors knowledge, the study is the foremost to develop an integrated empirical framework for work from home culture and its antecedents and consequences. The study has several important implications for managers.

Abstract
Research methodology
The case was developed from secondary sources and interviews with a security analyst. The secondary sources include company annual reports, news reports, analyst reports, industry reports, company websites, stock exchange websites and databases such as Bloomberg and CMIE Prowess.
Case overview/synopsis
Increasing competition in product and capital markets has put tremendous pressure on managers to become more cost competitive. To address their firms' uncompetitive cost structures, managers may have to consider dramatic restructuring of their businesses. During 2014–2017, Tata Steel Ltd (TSL) UK considered a series of divestitures and a merger plan to nurse the company back to health. The case considers the economics of the restructuring plan. The case is designed to help students analyze a corporate downsizing program undertaken by a large Indian company in the UK and to highlight the dynamic role of the CFO and governance issues in family firms. It introduces students to issues surrounding a typical restructuring and provides students a platform to practice the estimation of value creation in a restructuring exercise. While some cases on corporate restructuring in the context of developed economies are available, there are very few cases written in an emerging market context. This case bridges that gap. TSL presents a unique opportunity to study corporate restructuring necessitated by a failed cross-border acquisition. It illustrates the potential for value loss in large, cross-border acquisitions. It shows how managerial hubris can prompt family firm owners to overbid in acquisitions and create legacy hot spots. In addition, the case can be used to discuss the causes of governance failures such as weak institutional monitoring and poor legal enforcement in emerging markets that could potentially harm minority shareholders.
Complexity academic level
The case was developed from secondary sources and interviews with a security analyst. The secondary sources include company annual reports, news reports, analyst reports, industry reports, company websites, stock exchange websites and databases such as Bloomberg and CMIE Prowess.

Abstract
Purpose
This paper is the third part of a research effort that aims to identify how various crises affected basic business processes using Institut Européen d'Administration des Affaires (INSEAD’s) industrial excellence framework (IEF) in large organizations.
Design/methodology/approach
This research compares three data sets from the same four companies against quality management benchmarks, with a span of more than two decades: (1) data collected in 2005 operating under a financially thriving corporate environment; (2) data collected in 2015, operating under a strong financial crisis and (3) data collected in 2022, operating under the serious COVID-19 crisis.
Findings
The authors identify the characteristics that helped them navigate successfully through almost two crises in a row. These companies successfully navigated crises by applying assessment and continuous improvement processes, forging close relationships with their suppliers and training their people systematically.
Practical implications
The findings can be adopted by practitioners who wish to navigate their organizations during serious crises. Researchers and academics may also find this study interesting for managing quality during a pandemic.
Originality/value
There are not many studies that investigate how the pandemic influenced the quality management practices in organizations in Greece in sequential crises. This paper brings insights into the enduring advantages of adopting a quality framework.

Abstract
Purpose
The study aims to describe the main classes of antioxidants existing in fruit, beverages, vegetables and herbs and the different extraction and application of antioxidants in food. Oxidative degradation of lipids, especially induced by reactive oxygen species, leads to quality deterioration of foods and cosmetics and could have harmful effects on health. A major challenge is to develop tools to assess the antioxidant capacity and real efficacy of these molecules. Recently, many review papers regarding antioxidants from different sources and different extraction and quantification procedures have been published. However, none of them has all the information regarding antioxidants (sources, extraction and application in food).
Design/methodology/approach
This paper tries to take a different perspective on antioxidants for the new researcher involved in this field.
Findings
Antioxidants from fruit, vegetables and beverages play an important role in human health, for example, preventing cancer and cardiovascular diseases and lowering the incidence of different diseases. A number of plant products act as scavengers of free radical species and so have been classified as antioxidants. Antioxidants are an important group of food additives that have the ability to protect against detrimental change of oxidizable nutrients and consequently they extend shelf-life of foods.
Research limitations/implications
Most of the antioxidants present in foods are phenolic and polyphenolic compounds, but their efficacy in food for the prevention of oxidation or in the body for dealing with oxidative stress and its consequences depends on different factors.
Originality/value
This study collected the last finding in the field of sources and applications of natural antioxidants.

Abstract
Purpose
The purpose of this study is to investigate the effect of two unique processing routes (solvent jetting (SJ) and binder jetting (BJ)), on the green density of printed stainless steel 316L (SS316L) and Nickel (Ni) powders.
Design/methodology/approach
In the SJ processing route, a solvent is jetted unto the powder/binder mixture to selectively activate the binder, layer by layer. In the BJ processing route, a solution of the binder mixture is jetted onto the powder bed to selectively bind powder particles. The effects of printing parameters such as layer height, roller speed, shaker speed and nozzle temperature on the green density of printed components are investigated and compared for both processing routes.
Findings
Results show that layer height and nozzle temperature affect the relative density of the printed compact for both processing routes. Slightly higher relative densities were achieved via the SJ route, with the overall highest relative density being 42.7% at 100 µm layer height and 70% nozzle temperature for the SS316L components and 43.7% at 150 µm layer height and 90% nozzle temperature for the Ni components, respectively. Results also show an increase in the final sintered relative density with an increase in green (printed) relative density of the solvent jetted SS316L components, with the highest relative density being 87.2%.
Originality/value
The paper studies the influence of printing parameters on the green density of printed SS316L and Ni samples in an unprecedented effort to provide a comparative understanding of the process-property relationships in BJ and SJ of SS316L and Ni components to the additive manufacturing research community.

Abstract
New Zealand is a country of many cultures and ethnicities. With a growing Asian community, cultural capability of the mental health workforce is essential to ensure that Asians have equity in access to appropriate and high quality services. Literature indicates a growing need to develop resources and enhance knowledge on cultural competence to assist health service providers to address the needs of people from diverse backgrounds. Yet, at what stage of training and/or practice are health professionals gaining access to this knowledge?Consultation with local health services and tertiary education institutions revealed a gap in the knowledge of Asian mental health being taught in the curriculum of students undertaking training to become health professionals. Further research indicated a need and desire from tertiary institutions to have access to Asian mental health material for both enhancing students' learning, and promoting the concept of continuing education following graduation. As a result, an interactive, self‐administrative CD‐rom comprising three modules: self‐reflection; Asian philosophies; and clinical issues was compiled.Early feedback indicates that the CD‐rom has tremendous potential in terms of applicability to enhancing current curriculum and for teaching students skills such as accessing articles and web based resources, valuable for the purposes of continuing education. Continuing education with regards to cultural competence is not just for qualified health professionals but needs to be integrated as part of students training as health practitioners, in order to ensure health care providers are able to provide effective and culturally responsive services.

Abstract
The body has been one of the central tools in analysing connections between sport and postcolonialism in India, given how sport was an essential part of the colonial ‘civilising’ mission, which involved disciplining and controlling Indian bodies. Any discursive understanding of sport and postcolonialism in India must consider how it relates to existing concepts of the body and shapes the experiences of the people involved in it – acknowledging not just the power of colonialism in moulding sporting experiences but also the force of internal hierarchies that exist in Indian society. This chapter explores the experiences of students who studied in higher educational institutions in Kerala under the ‘sports quota’, a system that reserves seats in colleges/universities for high-performing sportspersons in India. Through their interviews, the sustained exclusion of the sporting body in contemporary Indian pedagogy is illustrated here. Specifically, the continuing prevalence of the colonial emphasis on the sporting body, as one whose strength and instrumentality are paramount, as well as its corollary postcolonial position, which treats this sporting body as inferior to the ‘refined mind’ of studious pupils, can be observed. Approaching the sports quota with a decolonising lens would require re-examining the disembodied nature of pedagogy in India’s higher educational institutions, acknowledging sporting students’ lived experiences, and a seamless integration – as opposed to separation/exclusion – of the sportsperson into higher education.

Abstract
Purpose
This paper aims to study the influence of the binder saturation level on the accuracy and on the mechanical properties of three-dimensional (3D)-printed scaffolds for bone tissue engineering.
Design/methodology/approach
To study the influence of the liquid binder volume on the models accuracy, two quality test plates with different macropore sizes were designed and produced. For the mechanical and physical characterisation, cylindrical specimens were used. The models were printed using a calcium phosphate powder, which was characterised in terms of composition, particle size and morphology, by X-ray diffraction (XRD), laser diffraction and Scanning electron microscopy (SEM) analysis. The sample’s physical characterisation was made using the Archimedes method (porosity), SEM, micro-computer tomography (CT) and digital scan techniques, while the mechanical characterisation was performed by means of uniaxial compressive tests. Strength distribution was analysed using a statistical Weibull approach, and the dependence of the compressive strength on the porosity was discussed.
Findings
The saturation level is determinant for the structural characteristics, accuracy and strength the models produced by three-dimensional printing (3DP). Samples printed with the highest saturation showed higher compressive strengths (24 MPa), which are over the human trabecular bone. The models printed with lower saturations presented the highest accuracy and pore interconnectivity.
Originality/value
This study allowed to acquire important knowledge concerning the effects of shell/core saturation on the overall performance of the 3DP. With this information it is possible to devise scaffolds with the required properties for bone scaffold engineering.

This study aims to improve the stiffness of as-printed handles by finding appropriate printing orientations.
Abstract
Purpose
This study aims to improve the stiffness of as-printed handles by finding appropriate printing orientations.
Design/methodology/approach
First, a series of benchmark handles is designed using Taguchi method. Then, for each uniformly sampled printing orientation, every benchmark handle is sliced and undergoes stiffness evaluation (i.e. displacement and mean stress) by using finite element analysis (FEA). This generates a substantial batch of handle-orientation-stiffness samples. With the data, an effective stiffness-prediction network is developed based on the artificial neural network. Finally, using the developed network, the particle swarm optimization is adapted to determine the optimized printing orientation for each input handle, aiming to improve its stiffness.
Findings
Compared with the common slicing software, the printing orientations proposed in this study, based on FEA, result in varying degrees of improvement in stiffness for four handles. Specifically, the displacement and mean stress are reduced by 16.86% and 18.14% on average. The experiments show that the approach has the potential to effectively improve the stiffness of a handle.
Originality/value
Although the anisotropic property in mechanics is unavoidable and difficult to formally describe in 3D printing, the proposed approach can effectively characterize the relationship between the stiffness and the printing orientation for each handle. And, it also can determine an optimized printing orientation for each handle to enhance its stiffness after printing.
