Abstract
Purpose
Prior investigations concerning misalignment resulting from journal deformation typically relied on predefined misaligned angles. Nevertheless, scant attention has been devoted to the determination of these misaligned angles. Furthermore, existing studies commonly treat the journal as rigid under such circumstances. Therefore, the present study aims to introduce a framework for determining misaligned angles and to compare outcomes between rigid and flexible journal configurations.
Design/methodology/approach
The bearing forces are considered as an external load leading to journal deformation. This deformation is calculated using the finite element method. The pressure distribution producing the bearing force is solved using the finite difference method. The mesh grids in the finite element and finite difference methods are matched for coupling calculation. By iteration, the pressure distribution of the lubricant film at the equilibrium position is determined.
Findings
Results show that the deformation-induced misalignment has a significant influence on the performance of the bearing when the journal flexibility is taken into account. The parametric study reveals that the misalignment relies on system parameters such as bearing length-diameter ratio and static load.
Originality/value
The investigation of this work provides a quantification method of misalignment of hydrodynamic bearings considering the elastic deformation of the journal, which assists in the design of bearing in a rotor-bearing system.

Abstract
Purpose
The purpose of this paper is to examine the role of protean-related traits and attitudes in the development of international mobility (expatriation) and entrepreneurial intentions among early career professionals. Career mobility is of increasing relevance to achieving career success in the era of protean and boundaryless careers, and in the present day highly globalized labor market. International mobility provides opportunities for work in organizations (corporate expatriation) as well as in entrepreneurship (expat entrepreneurship).
Design/methodology/approach
This paper reports two studies examining the role of “protean career personality,” conceptualized as consisting of personal initiative and flexibility on entrepreneurial and expatriation intention, looking at career orientation attitude as the mediating mechanism. In study 1, the impact of personal initiative and flexibility on the two career mobility paths is explored using a sample of 442 German undergraduate students. Study 2 replicates these relationships among a sample of 100 early career professionals who graduated with a diploma in psychology.
Findings
Results indicate that for the sample of undergraduate students, flexibility and career orientation were positively related to expatriation intention. However, the mediation path was non-significant. On the other hand, personal initiative and career orientation were essential for entrepreneurial intentions, with a significant mediation path. For the early career professionals in contrast, only flexibility turned out to be resourceful for both expatriation and entrepreneurial intentions.
Practical implications
Suggestions for supporting early career professionals to develop interest in working abroad or in entrepreneurship are provided. Particularly, the results indicate that protean traits affect mobility intentions differently. To strengthen intentions for expatriation work, attention should be paid enhancing the ability for staying flexible when it comes to career choices. This applies to both undergraduate students and early career professionals. However, a strong career orientation is also essential to the development of expatriation intention among current students. On the other hand, enhancing proactivity could strengthen entrepreneurial intention among undergraduate students.
Originality/value
This study applies protean-related traits and attitudes; and how they work together in the development of mobility intentions among undergraduate students and early career professionals. The study reveals differential roles of these traits and attitudes among these groups, with regard to expatriation and entrepreneurship. This is important for career guidance.

Abstract
We examine a large sample of some 100 economies worldwide to study the impact of financial sector size expansion on labor market performance. Simple linear dynamic panel data models inspired by the well-developed finance-growth literature suggest that (on average) a larger financial sector is beneficial for the labor market as it reduces unemployment rates. However, estimating country- and period-specific benchmark levels of financial sector size, we document that the relative contribution of finance vanishes with excessive levels of finance, and excessive levels of credit may actually be detrimental to employment. These non-linearities in the finance-unemployment nexus are more pronounced within developed economies. Overall, our study sheds new light on the ongoing controversy about the impact of the financial sector on societal well-being and highlights the importance of monitoring the expansion of the financial sector, in particular when it comes to credit markets.

Abstract
Corporate governance has experienced numerous changes in chime with the exigencies of the time during which it has been introduced or the context in which it has been practiced. Its gestation can be divided into three stages of development namely the traditional governance, the current transitional governance, and the upcoming sustainable governance. Traditional governance refers to the period hitherto the industrial revolution when corporations have not yet been formed, in today’s sense, but the governance structures were already in place in the existing entities at the time. Transitional governance refers to a period between the industrial revolution and the information age when corporations started to rise as a new economic entity. Reviewing the dominant corporate governance models are integral to understanding the transitional era. At the end of the transitional governance era, a transmogrification in corporate governance is underway to prepare itself for the coming age of sustainability. Sustainable governance integrates the principles of systems thinking and appreciates the complexity of decision-making environment, contrary to its former iterations that welcomed oversimplification of interactive messes (systems of problems). The objective of this chapter is to review corporate governance developmental transition toward sustainable governance and its role in the age of sustainability.

Abstract
Purpose
The purpose of this paper is to reflect upon the politics of and in organizational transformations in the wake of the fall of the Berlin wall and Germany's reunification.
Design/methodology/approach
The paper juxtaposes a political‐philosophical perspective informed by Rancière – what we call a dramaturgy of politics – with the findings of an ethnographic study conducted in the Berlin State Library in 2002/2003.
Findings
The paper outlines a reading of the event of November 9, 1989 and its aftermath as a dissensual event of politics proper, i.e. the emergence of a new political subjectivity, followed by a consensual process of social organization. In the state library, both the consensual “fantasy of the organizational One” as well its disruption are causing struggles over what is visible and sayable. A dramaturgy of politics thus encourages us to add our voices to the specific time‐spaces in which an excess of words, signs and forms alters the configuration of what is visible and expressible.
Research limitations/implications
The usual disclaimers about the limits of ethnographic research apply. The paper calls for further inquiries into the dramaturgy of organizational politics. It also reflects upon the “Western gaze” and the problematic of “speaking for” the presumably dominated.
Originality/value
It is hoped that the paper contributes to the understanding of the politics of organization (theory) by outlining an alternative conceptual approach and confronting it with ethnographic findings.

Abstract
This chapter addresses the question of what normatively binding claims can be associated with the principle of sustainability. It proposes a theoretical reading of justice that requires a new level of morality, namely a global (spatial), intergenerational (temporal) and ecological (material) extension of the scope of responsibility. This makes it plausible that responsibility for those who are distant in space and time, as well as for nature, becomes a matter of conscience. At the same time, it is shown how the binding claims resulting from the principle of sustainability can be internalised in the course of a conscience formation and how the gap between knowledge and action in questions of sustainable development can be closed by means of an emotional underpinning. Finally, it is proposed to transfer the question of conscience to spatial units and tourism through the model of ‘Destination Conscience’ and to institutionalise the idea of ‘inner commitment’ or self-commitment. One suggestion is the creation of committees that could be a collective ethical conscience for the future issues.

Abstract
Purpose
More and more organizations make parts of their information systems available to their business partners and often face integration and interoperability issues. To counter these problems, web services appeared as a promising technology to bridge the gap between organizations and their partners. While web services generally focus on the implementation of functional concerns (FC) such as ordering of goods, the reservation of flights, etc. also non‐functional concerns (NFC) such as security, reliable messaging, performance, and availability have to be addressed appropriately. The purpose of this paper is to identify web services' requirements.
Design/methodology/approach
In this paper the authors provide a survey on works in the area of NFCs in web services. After presenting a common terminology, the most important requirements in that context are presented. Further, the authors assess these works against the requirements.
Findings
The evaluation reveals that there is no approach that supports the requirements to a satisfying degree. Based on that, the authors motivate the need for a novel holistic approach to NFCs in web services.
Originality/value
The paper presents an extended version of one of the papers presented at iiWAS2010.

Abstract
Purpose
The purpose of this paper is to evaluate the influence of top management team diversity on academic excellence in universities. Academic excellence is conceptualized as successfully gaining funds for inter-organizational research collaborations, interdisciplinary graduate schools and high-ranked scientific reputation.
Design/methodology/approach
The study applies upper echelon theory to universities. Three hypotheses are developed: (overall) top management team heterogeneity is positively associated with successful funding of excellence clusters, (overall) top management team heterogeneity is positively associated with successful funding of graduate schools and (overall) top management team heterogeneity is positively associated with academic reputation. The empirical study is based on a cross-sectional dataset with a time lag, covering characteristics of 75 German public universities from 2008 to 2013. Multiple-regression analysis is applied to test the hypotheses.
Findings
Our results indicate that disciplinary and educational diversity of upper echelons has a positive effect on the outcomes. Other top management team characteristics (age, gender, etc.) show no significant effects. Besides top management team composition, we find that a high number of faculties and a broad inclusion of internal status groups (students, tenured faculty, academic and administrative staff) and external stakeholders in decision making processes may enhance academic excellence of universities.
Research limitations/implications
First, the study contributes to the body of literature concerned with higher education. It is situated at the crossroads of management studies and higher education research, unlocking strategic management theorizing for the public context. Furthermore, the study contributes to the body of literature on strategic leadership in pluralistic organizations. It highlights the importance of heterogeneous governance structures and modular organization designs for achieving academic excellence.
Practical implications
The paper may inform practitioners in administrative or leading positions and policy-makers concerned with higher education. The more diverse a top management team is in terms of multiple disciplinary backgrounds, the more likely they succeed in driving the university toward academic excellence.
Originality/value
The study is among the first to evaluate the influence of top management teams in universities with a quantitative research design.
