Abstract

Purpose

Bearings in field applications with high dynamic loading, e.g. wind energy plants, suffer from sudden failure initiated by subsurface material transformation, known as white etching cracks in a typical scale of μm, preferably around the maximum Hertzian stress zone. Despite many investigations in this field no precise knowledge about the root cause of those failures is available, due to the fact that failure under real service conditions of wind energy plants differs from what is known from test rig results in terms of contact loading, lubrication or dynamics. The purpose of this paper is to apply Barkhausen noise measurement to a full bearing test ring running under conditions of elastohydrodynamic lubrication (EHL) with high radial preload.

Design/methodology/approach

Full bearing tests are carried out by use of DGBB (Deep Grove Ball Bearings) with 6206 specification, material set constant as 100Cr6, martensitic hardening, 10‐12 percent maximum retained austenite and radial preload of 3500 MPa. Speed is set 9000 rpm, temperature is self setting at 80°C by test conditions. For tests, synthetic hydrocarbon base oil (Poly‐α‐Olefine) with a 1 percent amount of molydenum‐dithiophosphate (organic chain given as 2‐ethylhexyl) was used.

Findings

Non‐destructive fractal dimension analyses by use of Barkhausen noise measurements is of versatile value in terms of recording bearing manufacturing processes, but can also be part of non‐destructive condition monitoring of bearings in field applications, where predictive reactive maintenance is crucial for availability of the plant.

Research limitations/implications

Barkhausen noise signal recording may also be valuable for case studies related to microstructure changes of steel under operation conditions. Bearings are exposed in plenty of conditions to phenomena such as straying currents, subsequently straying magnetic fields. Hardly anything is known about how microstructure of bearing steel is susceptible to such conditions. This will be part of further studies.

Originality/value

Results given in the paper show that sudden bearing failure, according to formation of subsurface material property changes might be driven by activities of dislocations. Since those activities start with sequences of stress field‐induced formation of domains, later by formation of low‐angle subgrains, and at least phase transformation, recording of the Barkhausen signal would lead to real predictive condition monitoring in applications where a highly dynamic loading of the contact, even with low nominal contact pressure leads to sudden failure induced by white etching.

Abstract

Research on mentorship has been dominated by the West and little is known about the cultural variations of the mentoring phenomenon in Asian countries. A richer understanding of the cultural context that is more attuned to mentoring experience in Asia can help to improve workplace experience, in general, for those working in and for those who intend to work in the region. This chapter captures the important theoretical lenses in the mentoring literature, and also provides a clear demarcation between negative mentoring and dysfunctional mentoring. This is followed by contextualizing mentoring as per four of Hofstede's six cultural dimensions by dwelling on mentoring experience in countries such as China, India, Pakistan, Japan, South Korea and Taiwan. It is hoped that this chapter will pave the way for further research, which may be a precursor for theory development.

Abstract

As proposed in this paper, in public accounting firms, supervisors and managers provide junior accountants with career-related benefits that include: career development support; social support; and role modeling. Also, employees who receive such career-related benefits are more likely to believe that the firm provides career growth opportunities and more likely to trust their managers. Career growth opportunities and trust, in turn, positively affect organizational commitment, which reduces turnover intentions. In summary, the relation between career benefits and turnover is mediated by several variables: career growth opportunities, trust in managers, and organizational commitment. Results of a survey of junior employees in public accounting firms support these assertions (with the exception of social support).

Abstract

Purpose

The authors aim to examine the relationship between home bias and globalization while specifically examining the effects of the different dimensions of globalization (social, economic and political) for both developed countries and developing countries. Additionally, the authors test the effect of globalization regulation and laws against actual globalization activities.

Design/methodology/approach

This study investigates the influence of globalization on the home bias phenomenon using a panel regression and a three-dimensional globalization index (social, economic and political globalization) of 42 developed and developing countries from 2001 to 2016.

Findings

The results show that globalization significantly reduces home bias. In addition, the authors find that social globalization has a key influence compared to economic globalization and that political globalization has the weakest effect. For developing economies only, economic globalization as well as globalization laws and regulations have a crucial impact on the level of home bias.

Originality/value

Prior studies focus merely on the aspect of financial integration. Our study provides a more comprehensive outlook by distinguishing between the features of globalization (social, economic and political) as well as the actual globalization activities (de facto) compared to the laws and regulations enabling those actives (de jure). Lauterbach and Reisman (2004) show that globalization reduces home bias through a theoretical model. This study provides empirical merit to their work. In addition, we examine the different aspects of globalization for both emerging and developed markets.

Abstract

Scanning both the academic and popular business literature of the last 40 years puzzles the alert reader. The variety of prescriptions of how to be successful (effective, performing, etc.) 1 Organizational performance, organizational success and organizational effectiveness will be used interchangeably throughout this paper.1 in business is hardly comprehensible: “Being close to the customer,” Total Quality Management, corporate social responsibility, shareholder value maximization, efficient consumer response, management reward systems or employee involvement programs are but a few of the slogans introduced as means to increase organizational effectiveness. Management scholars have made little effort to integrate the various performance-enhancing strategies or to assess them in an orderly manner.

This study classifies organizational strategies by the importance each strategy attaches to different constituencies in the firm’s environment. A number of researchers divide an organization’s environment into various constituency groups and argue that these groups constitute – as providers and recipients of resources – the basis for organizational survival and well-being. Some theoretical schools argue for the foremost importance of responsiveness to certain constituencies while stakeholder theory calls for a – situation-contingent – balance in these responsiveness levels. Given that maximum responsiveness levels to different groups may be limited by an organization’s resource endowment or even counterbalanced, the need exists for a concurrent assessment of these competing claims by jointly evaluating the effect of the respective behaviors towards constituencies on performance. Thus, this study investigates the competing merits of implementing alternative business philosophies (e.g. balanced versus focused responsiveness to constituencies). Such a concurrent assessment provides a “critical test” of multiple, opposing theories rather than testing the merits of one theory (Carlsmith, Ellsworth & Aronson, 1976).

In the high tolerance level applied for this study (be among the top 80% of the industry) only a handful of organizations managed to sustain such a balanced strategy over the whole observation period. Continuously monitoring stakeholder demands and crafting suitable responsiveness strategies must therefore be a focus of successful business strategies. While such behavior may not be a sufficient explanation for organizational success, it certainly is a necessary one.

Abstract

Purpose

The purpose of this paper is to examine the ways for the formulation of a model for calculating the cost of corruption per country, taking into account the social cost.

Design/methodology/approach

The methodology is practical exploration; the model is formulated along with the social cost of specific calculation. Based on two specific acts of corruption, bribery and overpricing of public works, these acts are private and public corruption. From there, the model is formulated along with the social cost of specific calculation, based on two specific acts of corruption, bribery and overpricing of public works.

Findings

This paper concludes that the model is applicable to all the countries of the world, based on their tax structure.

Research limitations/implications

Limitations do not exist in the model; the additional implications are the extension of the model. The model can be used for local governments or countries.

Practical implications

Countries can calculate the theoretical cost of corruption in their local, regional or national economies, based on two specific acts of corruption, in political, private and public corruption; bribery and overpricing of public works.

Social implications

The social implications include knowing the theoretical cost of corruption and their effects.

Originality/value

The model calculates the cost of corruption and its economic and social impact.

Abstract

Given the ways in which the research pressures on university staff are becoming seemingly ever greater, an issue of the European Journal of Marketing that is given over to a survey of the kinds of research initiatives which are currently being carried out is timely. The study which provides the basis for this was conducted between December 1994 and February 1995, with questionnaires being sent to staff in universities throughout Europe. At the time the final selection was made, a total of 150 responses had been received from 18 countries.

Abstract

Purpose

The purpose of this paper is to show how controlled exposure of electromagnetic fields toward bearing steel vulnerates the microstructure. The ability of Barkhausen Noise signal processing is used for detecting phenomena such as dislocation and subgrain formation processes as the beginning of later failures.

Design/methodology/approach

A Barkhausen noise signal measurement equipment is used for detecting subsurface distress of 100Cr6 as a function of the applied electromagnetic and mechanical stress. Barkhausen noise signal is mathematically processed by use of fractal dimension analysis.

Findings

The paper cleary reveals significant impact of electromagnetic field in junction with mechanical loading. Electromagnetic impact depends on the magnitude of the field.

Research limitations/implications

Research limitations are given by the fact that in real field applications, e.g. wind power plants, bearings are exposed by multiple influences and the methodology is not applicable to those conditions.

Practical implications

The methodology can be applied to real field applications in condition monitoring systems. Up to now, no reasonable on‐line measurement is in use determining sub surface fatigue phenomena. The paper hence, reveals the possibility to raise condition monitoring into a new perspective.

Originality/value

The use of Barkhausen noise signal processing, as presented here, is original with respect to real field applications, such as wind power plants with a high demand in condition monitoring, especially off‐shore plants.

Abstract

Purpose

The purpose of this paper is to review relevant literatures on career success and develop a theoretical framework and testable propositions concerning how human capital, person‐environment fit and organizational support relate to career success. Whilst acknowledging the substantial literature that has accumulated regarding the various antecedents and operationalizations involved in employees' career success, there is little research as how person‐environment fit and career success are related.

Design/methodology/approach

Literature outlining approaches to career success is summarized and research at the intersection of person‐environment fit and organizational support/career success are reviewed. This is followed by a set of propositions based upon the antecedents of career success.

Findings

It is suggested that person‐environment fit and organizational support are important antecedents of career success. Knowledge of career changes and these antecedents help individuals and organizations manage career success.

Research limitations/implications

Future research should examine empirically the linkages suggested by the paper along with other relationships asserted or implied by person‐environment fit and career success literature as mentioned in the paper.

Practical implications

Both employers and employees may benefit from integrating different types of fit into the psychological contract because each fit will impact aspects of career success. Therefore, organizations need to select and develop employees that can easily adjust and fit into careers that are compatible with their work environments.

Originality/value

This paper contributes to the literature by being one of the first to examine the effects of different types of person‐environment fit on career success.
