Abstract
Purpose
Fix-position preloading, centrifugal force and higher temperatures cause the bearing units in angular contact ball bearings to expand, changing the contact load and affecting bearing life. This study aims to examine the effect of thermal and centrifugal expansion on the fatigue life of fix-position preloaded angular contact ball bearings in high-speed operating conditions.
Design/methodology/approach
The contact loads on the inner and outer bearing rings were resolved according to the thermal and centrifugal expansion factors in the quasi-static position preloading model. The pressure and frictional stress distribution were used to calculate the subsurface stress in the contact area, while the Zaretsky model was used to determine the relative fatigue life of the inner and outer bearing rings.
Findings
Under fix-position bearing preloading, thermal and centrifugal expansion significantly affected the contact load and relative fatigue life. At the same axial preload, the inner ring contact load was higher than the outer ring contact load, with a maximum difference of 132.3%. The decrease in the inner ring relative life exceeded the outer ring contact load, with a maximum difference of 7.5%, compared to the absence of thermal and centrifugal expansion.
Originality/value
This study revealed the influence of thermal and centrifugal expansion on the fatigue life of angular contact ball bearings in high-speed service conditions.

Abstract
Purpose
In this study, to empirically test the relationship between ethical organizational climate, inner life (IL) and life satisfaction (LS) of employees, a field study was conducted on white-collar personnel working in the service sector in the Istanbul region. The main purpose was to extract an approach that could be applied to simultaneously boost LS and customer orientation for effective service delivery by organizations.
Design/methodology/approach
A two-wave time-lagged survey design was used to collect the data over a period of three months. Two sets of self-administrated survey questionnaires were developed for both waves, containing the details of the study and items for measuring variables. The questionnaires were developed in such a manner that the anonymity of the respondents and ethical considerations remained intact. In the first wave, data were collected for two variables, i.e. organizational ethical climate and IL. The measurement scale for organizational ethical climate was adapted from the study of DeBode et al. (2013) and for IL from the study of Fry et al. (2017). In the second wave, data on the remaining two variables (LS and organizational customer orientation) were collected. Direct effects and indirect effects in the hypotheses were tested by structural equation modeling (SEM).
Findings
This study has found that the organizational ethical climate strengthens the inner lives of employees, which is vital for the organizations from two angles: one, strong IL of an employee enhances his/her own LS and two, stronger IL accentuates customer orientation.
Research limitations/implications
The fact that the context of this study is limited to Turkey and that the participants are selected from among white-collar personnel working in the service sector reduces the representativeness of the research result. In this sense, in the next stages, the model of the research can be retested in different industries or cross-cultural studies can be designed by comparing the study results with samples from different geographies, so that the validity of these relations for different cultures can be seen.
Practical implications
The implications of this study revealed that employees will enjoy their lives more when authorities in organizations adopt organizational policies supporting the inner lives of employees, feel respect for their private areas and make the organizational climate more ethical. Hence, with practices such as workplace spirituality or spiritual leadership that support the inner lives of employees, the motivation and satisfaction of employees can be increased.
Social implications
This study revealed that inner life strength makes people comparative more ethical in their dealings, which gives them a sense of achievement and enhances work meaningfulness, boosting LS and customer-orientation. The findings of this study are vital for leaders, as they can achieve a conjoint elevation of the LS of their employees and enhance customer orientation for higher organizational performance.
Originality/value
This study is original in emphasizing the positive effect of spiritually powerful inner-life customer-orientedness in employees with empirical proof.

Abstract
A collection of essays by a social economist seeking to balance economics as a science of means with the values deemed necessary to man′s finding the good life and society enduring as a civilized instrumentality. Looks for authority to great men of the past and to today′s moral philosopher: man is an ethical animal. The 13 essays are: 1. Evolutionary Economics: The End of It All? which challenges the view that Darwinism destroyed belief in a universe of purpose and design; 2. Schmoller′s Political Economy: Its Psychic, Moral and Legal Foundations, which centres on the belief that time‐honoured ethical values prevail in an economy formed by ties of common sentiment, ideas, customs and laws; 3. Adam Smith by Gustav von Schmoller – Schmoller rejects Smith′s natural law and sees him as simply spreading the message of Calvinism; 4. Pierre‐Joseph Proudhon, Socialist – Karl Marx, Communist: A Comparison; 5. Marxism and the Instauration of Man, which raises the question for Marx: is the flowering of the new man in Communist society the ultimate end to the dialectical movement of history?; 6. Ethical Progress and Economic Growth in Western Civilization; 7. Ethical Principles in American Society: An Appraisal; 8. The Ugent Need for a Consensus on Moral Values, which focuses on the real dangers inherent in there being no consensus on moral values; 9. Human Resources and the Good Society – man is not to be treated as an economic resource; man′s moral and material wellbeing is the goal; 10. The Social Economist on the Modern Dilemma: Ethical Dwarfs and Nuclear Giants, which argues that it is imperative to distinguish good from evil and to act accordingly: existentialism, situation ethics and evolutionary ethics savour of nihilism; 11. Ethical Principles: The Economist′s Quandary, which is the difficulty of balancing the claims of disinterested science and of the urge to better the human condition; 12. The Role of Government in the Advancement of Cultural Values, which discusses censorship and the funding of art against the background of the US Helms Amendment; 13. Man at the Crossroads draws earlier themes together; the author makes the case for rejecting determinism and the “operant conditioning” of the Skinner school in favour of the moral progress of autonomous man through adherence to traditional ethical values.

Abstract
Urban sociological research posits a strong correlation between social isolation and the growth in illicit activities of street culture, namely the drug trade and violent gang activities. However, in this article we offer an explanation for why, even in the absence of extreme poverty and social isolation from mainstream institutions, youths in Cambridge, Massachusetts feel vulnerable to illicit street cultural activities. We also offer an explanation for why these youths perceive the effects of social dislocation to be similar to that experienced by youths from larger central cities. As we will elaborate below, some students in Cambridge are affected by illicit street cultural activities because: (1) social dislocation is a relative phenomenon and not merely an absolute phenomenon as described by William J. Wilson; (2) there is a social dislocation spill‐over effect from larger central cities that intensifies or amplifies the experiences of youths in the relatively poorer neighborhoods of Cambridge; (3) and some youths, from stable working‐class or wealthier neighborhoods in Cambridge, view involvement in the illicit activities of street culture as a reputable means of gaining peer respect through status group affiliation.

Abstract
Purpose
The paper aims to study the influence of three dimensions of workplace spirituality (inner life, meaningful work and sense of community) on perceived and objective organizational performance in two primary health care settings: health centres (HCs) and family health units (FHUs), differing in terms of work organization.
Design/methodology/approach
Data on workplace spirituality and perceived organizational performance were collected from a sample of 266 health care workers (doctors, nurses and administrative staff). Data on objective performance were obtained from the respective regional health authorities. Multiple regression, GLM, and tests of mediation were carried out.
Findings
In both groups, perceived and objective organizational performance are predicted by sense of community. Additionally, FHUs presented significantly higher values in perceived and objective organizational performance, as well as sense of community and meaningful work. Finally, workplace spirituality and sense of community were found to mediate the relationship between work group and perceived and objective organizational performance.
Research limitations/implications
The study's limitations include the convenience sample, as well as lack of control for the social desirability effect. Patient satisfaction surveys as well as the inclusion of predictive variables such as leadership should be considered in future studies.
Practical implications
Primary health care services, and particularly FHUs, revealed the importance of workplace spirituality. Work teams with higher sense of community had higher performance results, which may therefore be an input in policy decisions regarding primary health care.
Originality/value
This study compared the scores of workplace spirituality and perceived and objective organizational performance in two types of primary health care services, in a setting that approximates the quasi-field experiment. Workplace spirituality emerged as significantly mediating the relationship between work unit type and organizational performance.

Abstract
Purpose
The authors, seven women–writers–performers–artists–academics, have been working collectively for a year, storying, de-storying and re-storying the experience of our lives. The authors write to “taste life twice, in the moment and in retrospect” (Nin, 1976), to uncover and learn ourselves through writing (Richardson, 1997), to take the “risky” steps of talking to each other about our inner lives (Palmer, 1998). Cognisant of the limitations and masculinities of traditional academic discourses, in form and content, and heavily confined by neoliberal expectations to count and be counted, we write and express the stories of lives the authors did not choose or imagine – lives we are given and live through. Our expression inhabits aesthetic, contemplative and sensory ways of knowing and employs poetry, image, song and story to create a polyvocal account of women’s lives, voices, struggles and learning. The authors share here part of our collective memoir and its development. The paper aims to discuss these issues.
Design/methodology/approach
This paper is designed as a collective memoir.
Findings
The authors write and express the stories of lives we did not choose or imagine – lives we are given and live through. The expression inhabits aesthetic, contemplative and sensory ways of knowing and employs poetry, image, song and story to create a polyvocal account of women’s lives, voices, struggles and learning. The authors share here part of our collective memoir and its development.
Research limitations/implications
The research focuses on autoethnography and lived experience.
Originality/value
Auto-ethnography/lived experience offers rich insights into the personal and political actions and actors within higher education.

Abstract
Purpose
Many sales organizations use traditional control systems such as agency theory, which entails motivating salespeople using rewards and punishments, as if they are mechanical beings that are devoid of emotions and spirit. Research shows that such control leads to dissatisfied customers, disengaged salespeople and poor organizational reputation. The purpose of this study is to present governance based on workplace spirituality as an alternative approach, wherein salespeople’s emotional and spiritual development is given primary importance. This is proposed to result in favorable performance and behaviors in alignment with organizational and customer goals.
Design/methodology/approach
The study builds a conceptual model from an extended literature review.
Findings
The developed conceptual model for workplace spirituality-based governance in sales organization consists of organizational structural factors, such as control and reward systems, as antecedents of psychological experiences of workplace spirituality in salespeople. These experiences are then proposed to result in salespeople’s increased customer orientation and objective performance, with organizational commitment as a mediator.
Practical Implications
The study has implications for organizations that govern salespeople by fiddling constantly with their salespeople’s incentive plans but find that most of these changes have little effect. The study proposes that companies will have more satisfied customers and successful salespeople, if they manage their salespeople’s emotional and spiritual side.
Originality/value
This study is the first to devise a governance system in selling organizations that is based on workplace spirituality.

Abstract
This chapter aims to consider workplace spirituality from a cross-cultural perspective. The terms workplace spirituality and culture are so intangible, and both start with the attitude and behavior of humans but are meaningful in a community. Because of the constraint of understanding these abstract settings, it is necessary to define and specify the dimensions of both concepts to achieve the aim of this chapter. In this regard, the section starts with the conceptuality of workplace spirituality and the dimensions of the term, which cumulate at individual, group, and organizational levels. It goes with the part of cultural dimensions in the light of Hofstede's (2001) direction, Chhokar, Brodbeck, and House's (2007) extension, and Sharma's (2010) derivation of cultural dimensions for national, organizational, and individual levels, respectively. After joining the dots, the chapter focuses on one of the most sacred research areas for academic literature, cross-cultural differences, and workplace spirituality. The last part of the chapter is the conclusion to point to final notes about the concepts and help guide future studies.

Abstract
How Steiner brought to bear the role of the imagination in reconciling ideological polarities on its function in an educational setting cannot be fully understood without examining the outlook on life from whence it sprang ‐ nor without touching upon historical developments in Western education and the extraordinary life and background of Rudolf Steiner himself. This paper uses historical, biographical and autobiographical commentary to develop an interpretation of the origin of Steiner’s notion of imaginative teaching.
