Abstract
Purpose
Bearings in electric machines often work in high speed, light load and vibration load conditions. The purpose of this paper is to find a new fatigue damage accumulation rating life model of ball bearings, which is expected for calculating fatigue life of ball bearings more accurately under vibration load, especially in high speed and light load conditions.
Design/methodology/approach
A new fatigue damage accumulation rating life model of ball bearings considering time-varying vibration load is proposed. Vibration equations of rotor-bearing system are constructed and solved by Runge–Kutta method. The modified rating life and modified reference rating life model under vibration load is also proposed. Contrast of the three fatigue life models and the influence of dynamic balance level, rotating speed, preload of ball bearings on bearing’s fatigue life are analyzed.
Findings
To calculate fatigue rating life of ball bearings more accurately under vibration load, especially in high speed and light load conditions, the fatigue damage accumulation rating life model should be considered. The optimum preload has an obvious influence on fatigue rating life.
Originality/value
This paper used analytical method and model that is helpful for design of steel ball bearing in high speed, light load and vibration load conditions.

Abstract
Purpose
The investigation of the relationship between the future of humanity and the future of ecology is a pertinent issue. In this context, the study aimed to explore people's travel experience in the Himalayan region of India for transformation and well-being and how transformation induces their involvement in regenerative practices. The authors investigated if transformations contribute to the well-being of all living beings and the environment and induce involvement in regenerative practices?
Design/methodology/approach
The authors preferred qualitative research design and selected narrative inquiry as a research approach to bring individuals' life stories to the centre stage for examination. Accordingly, diachronic data was collected, and a paradigmatic type of narrative inquiry was applied that uses paradigmatic analytical procedures to produce thematic categories and taxonomies from the database.
Findings
Nine themes were identified and discussed in the light of existing literature. Transformational tourism promotes well-being and reduces mental health anomalies. The study participants used words like calm, compose, stress-free, and compassion, indicating enhanced consciousness. They also reported satisfaction and induced environmentally friendly behaviour after serving the community and environment at tourist destinations situated in Himachal Pradesh, Uttarakhand, and the Union territory of Ladakh of the Himalayan region of India.
Originality/value
The paper collates evidence to establish a correlation between transformation and regeneration. There is a suggestion that transformative travel leads to participation in regenerative activities. The paper is based on people's experiences described as green workers of the Indian Himalayas and provides empirical conclusions that support the argument of transformational induced regenerative tourism.

Abstract
Purpose
Humanity is facing an unprecedented challenge of climate crises. Rapid changes to the physical environment and living conditions will be accompanied by challenges to mental health and well-being. Consequently, education for sustainable development should also include coping strategies for stress and anxiety. Adding intra-personal skills to the curriculum, such as self-reflection and mindfulness training, could aid in this education. This case study aims to explore the barriers to and drivers for fostering inner transitions through intra-personal skills training and mindfulness.
Design/methodology/approach
This case study from Lund University, Sweden, constitutes a critical case for investigating inner transitions in education. Data collection was designed around semi-structured qualitative interviews, to investigate the barriers to and drivers for intra-personal skills and mindfulness in education for sustainable development at all institutional levels of the university.
Findings
The results indicate that education for sustainable development already includes elements of introspection, albeit informally. However, there is a lack in a fundamental understanding of intra-personal skills and how they relate to other key competences for sustainable development. To make intra-personal skills training a formal component of the education, it must receive the full support from all levels of the university.
Originality/value
The study outlines general recommendations for universities to challenge existing policies while also finding ways to work around them. In the meantime, universities should make intra-personal skills training an informal learning activity. Recognizing that the students’ prior knowledge in this area is a potential asset, universities should collaborate with their students to support student-led intra-personal skills training.

Abstract
Executive Summary
Every human being is spiritual and has spirituality, whether it is existential and subconscious or reflective and explicitly conscious. The existential subconscious level of spirituality informs and empowers our conscious decisions, choices, and actions. In this sense, spirituality is the continuous line of action that fashions our personal and collective human and cosmic identity. Despite our native spirituality that unites and harmonizes humanity, we also experience the fallen nature of the human heart and the resulting brokenness of human relations as the major cause of crises in our lives, families, corporations and nations, and now the life-threatening ecosystems that form our common planetary home. Hitherto, we have falsely presumed that the earth and the universe are for the use of mankind – an anthropocentric concept of ecology and sustainability. Hence, we are on the verge of destroying the planet. We need planetary ethics and cosmic spirituality to change our mind-set – from anthropocentricism to cosmocentricism and from being the conqueror of nature to being a caring partner of nature. This is the essence of corporate cosmic spirituality. Human spirituality in general and corporate executive spirituality in particular seem to be the best way to understand and offer a way out of the personal, communal, and planetary disorders of our age. This concluding note of this book is a summons to all corporate executives to rise to the call of cosmic spirituality.

Abstract
Executive Summary
This first chapter explores the basic foundation of corporate ethics: the human person in all its dignity and mystery, its corporeality and emotionality, and its cognitive and volitive capacities of moral development. Four fundamental characteristics of the human person, namely individuality, sociality, immanence, and transcendence, will be examined for their potential to understand, live, experience, and witness corporate ethics and morals. We explore the profound meaning and mystery of human personhood invoking several philosophies of the good and human dignity as exposed by Aristotle and Thomas Aquinas in the West, by the doctrine of Dharma in the East as expounded by Gautama Buddha, Mahabharata, and Bhagavad Gita, and by Prophets Confucius and Tao, in the East. Several contemporary cases of great human personhood are analyzed: for example, Peace Nobel Laureate Nelson Mandela from South Africa (1993) and Peace Nobel Laureate Liu Xiaobo from China (2017) – cases of human abuse that turned into triumphs of human dignity.

Abstract
Executive Summary
Rights and duties are involved in every area of business and markets, and society and governments. Most often, rights and duties involve serious ethical and moral issues of conflict. A good theory of the ethics of rights and duties, obligations, and responsibilities will empower us to understand the impact of our actions on various stakeholders. Additionally, a deep understanding of rights and duties could help us to analyze better the impact of our executive actions on various stakeholders and, in particular, to fathom the damaging effects of rights and duties violated by the man-made current financial crisis when seen from an ethical and moral point of view. Our coverage on the ethics of corporate rights and duties will comprise of two parts: Part 1: The Nature of Corporate Business Rights and Duties, and Part 2: Respecting Corporate Rights and Duties. The chapter will feature Newcomb Wellesley Hohfeld’s framework of legal interests such as claims, privileges, power, and immunity and its various applications to contemporary market and corporate executive situations. We illustrate the theory of rights and duties using several cases from the current turbulent markets.

Abstract
Executive Summary
This focal chapter deals with the understanding of important ethical theories used in executive moral reasoning such as teleology, deontology, distributive justice and corrective justice, virtue ethics versus ethics of trust, from the perspectives of intrinsic versus instrumental good, moral worth versus moral obligation, and moral conscience versus moral justification. Ethical and moral reasoning will power executives to identify, explore, and resolve corporate moral dilemma, especially in the wake of emerging gray market areas where good and evil, right or wrong, just or unjust, and truth and falsehood cannot be easily distinguished. We focus on developing corporate skills of awareness of ethical values and moral imperatives in current otherwise highly commoditized and turbulent human, market, and corporate situations. The challenges of morality are multifaceted and diverse. Professionals usually have self-discipline and self-regulation abilities, ego strength, and social skills. Morality in the professions is not concerned with the issues of rudimentary socialization; rather, the issues involve deciding between conflicting values, where each value represents something good in itself. There are problems in both knowing what is right, good, true, and just on the one hand, and on the other hand, in doing what is right and avoiding wrong, doing good and avoiding evil, and being fair and just while avoiding being unfair and unjust. Several contemporary cases will illustrate the challenging dimensions of ethical and moral reasoning, moral judgment and moral justification embedded in executive decision processes, and corporate growth and profitability ventures.

Abstract
Purpose
There is evidence that spirituality at the workplace has positive effects on work outcomes, and there are different models conceptualizing the construct. To date, there is no discussion highlighting how digitalization is affecting workplace spirituality and vice versa. The present review tries to close this gap by discussing the psychological dynamics in light of digitalization and spirituality in the context of work.
Design/methodology/approach
This is a conceptual discussion based on an extensive narrative review. The conceptual design is further tested with a real-life case study.
Findings
The result is a model that may guide future research, which consists of the four highly interdependent domains, namely psychology (with the dimensions of emotion, cognition and behavior), digitalization (with the dimensions of platforms, data and algorithms), spirituality (with the dimensions of meaning, self-transcendation and belonging), as well as the workplace (with the dimensions of work tasks, location, community and culture and values). The discussion includes implications for the future of work, suggestions for management decisions and potential future research directions.
Originality/value
To date, there are many discussions about digital transformation and a limited amount of them have invested in analyzing psychological dimensions. The application to spirituality and the workplace – especially when the two are combined – is almost wholly absent, which makes the present discussion both innovative and original.

Abstract
Purpose
Without competent and talented employees, no organisation can grow and sustain for a long time. It becomes essential for every organisation to retain and satisfy the employees to achieve their predetermined organisational goals. The present study examines the mediating effect of workplace spirituality dimensions (i.e. meaningful work, compassion, transcendence, mindfulness and sense of community) in the link between job satisfaction and organisational citizenship behaviour (OCB) among managerial employees of selected manufacturing firms of Chhattisgarh state.
Design/methodology/approach
Correlational research design was incorporated. Employees working at managerial positions at different private manufacturing firms of Chhattisgarh state were chosen as a sample for the present study. Regression analysis and confirmatory factor analysis tools were used to analyse the primary data collected from 400 respondents.
Findings
The results revealed that all the dimensions of workplace spirituality, i.e. meaningful work, compassion, transcendence, mindfulness and sense of community, were found statistically significant and partially mediated between job satisfaction and OCB among managerial employees of Chhattisgarh. The authors discussed the results thoroughly and provided avenues for the future research.
Research limitations/implications
The findings of the present research study will assist all private organisations in rethinking their employee retention and satisfaction strategies, since the presence of workplace spirituality in the organisation has a significant and beneficial impact on its environment. The current research will assist organisations in creating circumstances for OCB for employee via the introduction of workplace spirituality.
Originality/value
Creating spirituality in the current situation, where Covid-19 has suddenly affected all organisations around the world, would be extremely beneficial in terms of employee retention and satisfaction, which would eventually aid in the development of an environment conducive to citizenship behaviour at the workplace. However, the role of workplace spirituality as a mediator in the link between job satisfaction and OCB is innovative and has received little attention in the research community.
