Purpose – The broader aim of the research is to better understand the origins of firm heterogeneity in terms of strategy and structure, looking beyond convergence pressures resulting from economic and institutional forces.

Design/methodology/approach – To identify firm-specific differences, the paper uses an in-depth analysis of two matched cases, comparing the introduction of diversification strategies and decentralized organizational structures in two Dutch banks. Based on detailed archival research it tries to understand how different outcomes were shaped by political processes involving a variety of internal and external actors.

Findings – The research shows the importance of these processes and, in particular, the role of management succession as a trigger for organizational changes as well as the potential power of management consultants based on a combination of their own “political” skills and the opportunity provided by internal divisions. Moreover, the study confirms the view that organizational change requires a change in dominant ideology.

Research limitations/implications – The research was able to go beyond the limitations of extant studies based on cross-sectional data or single cases. It demonstrates the usefulness of historical analysis when examining changes in strategy and structure. Its results need to be confirmed by conducting similar studies in different contexts.

Originality/value – The paper provides new insights into the complex and dynamic processes of organizational change and shows how external consultants – within a specific set of circumstances – were able to manage these processes. The results are valuable to scholars studying organizational change and those looking at consultants and their role. They might also provide insights for practicing managers working or planning to work with consultants.

In this chapter, we advance an understanding of identity theory (IT) as originally created by Sheldon Stryker and developed over the past 50 years. We address misunderstandings of IT concepts and connections. We provide definitions of key ideas in IT, propositions that identify important relationships, and scope conditions that outline the circumstances to which IT applies. Our goal is to provide scholars with an accurate view of IT so that it can continue to advance the science of human behavior in sociology and beyond.

Purpose and approach – We examine theoretically and experimentally how unequal abilities to contribute affect incentives and efficiency when players compete for membership in stratified groups based on the contributions they make. Players have either a low or a high endowment. Once assigned to a group based on their group contribution, players share equally in their group’s collective output. Depending on the parameters, the mechanism has several distinct equilibria that differ in efficiency.

Findings – Somewhat counter to conventional expectation our theoretical analysis indicates that as long as certain assumptions are satisfied, efficiency increases rather than decreases the more abilities to contribute differ. The analysis also suggests various follow-up experiments about equilibrium selection, tacit coordination, and the effect of unequal abilities in systems with endogenous grouping. We conduct an experiment that shows that subjects tacitly coordinate the mechanism’s asymmetric payoff-dominant equilibrium with precision; this precision is robust to a change in the structure and complexity of the game.

Implications – The results suggest that people respond to merit-based grouping in a natural way and that competitive contribution-based grouping encourages public contributions even when abilities to contribute differ, which is the case in all communities and societies.

This chapter describes a theory of intergroup leadership. Research on reducing prejudice and intergroup conflict identifies a number of conditions, such as empathy, shared goals, crossed categorization, recategorization, and intergroup contact, which can be beneficial. It also identifies social identity threat as a stumbling block – processes intended to reduce conflict often threaten people’s sense of having a unique and distinctive social identity and thus provoke a defensive reaction that sustains conflict. But social psychology says little about the role of group leadership in conflict resolution.

I summarize what we know from social psychology about conditions that attenuate intergroup conflict; then focus on social identity and influence processes to present a new theory of leadership across conflicting groups.

Prejudice and intergroup conflict reduction rests on effective messaging and influence, which is often a matter of intergroup leadership where a leader must bridge and integrate warring factions within a superordinate entity. The challenge of intergroup leadership is to construct an intergroup relational identity that focuses on collaboration and avoids identity threat. I describe a model of intergroup leadership and discuss strategies, such as identity rhetoric, boundary spanning and leadership coalition-building, that such leadership should adopt to effectively reconstruct social identity to reduce conflict and prejudice between groups.

This is a development and extension of a more narrowly focused theory of intergroup leadership in organizational contexts. It will be of value to social psychology, the behavioral and social sciences, and those seeking to reduce prejudice and intergroup conflict through leadership.

Some cycle routes have proved unpopular because at several points a cyclist has to stop or slow very appreciably. Cyclists are discouraged by the resulting extra journey time. Three alternative hypotheses are made for a cyclist's performance in response to an imposed stop. In all he brakes uniformly from a cruising speed. In one, this speed is a personal standard, and he accelerates uniformly to regain it. In the second, because his energy is used in accelerating, he has less to use in cruising. The third hypothesis is that a cyclist's power output in accelerating is the same as in cruising, except at very low speeds, so that he attains his normal cruising speed asymptotically.

Trials were conducted on a lightly trafficked 2.5-km circuit with seven roundabouts. Cyclists made at least two circuits each, one non-stop and one stopping at roundabouts. Pairs of times for each cyclist were compared with derivations from each hypothesis. It was found that the estimates derived from the second hypothesis were much closer to the trial times than those given by the others. The conclusion is that making an adult cyclist stop is equivalent to extending the journey time by as much as an extra 50 m, approximately, would take. In reckoning the lengths of routes in order to select one for development, an equivalent distance of about 50 m should be added for each stop or near stop, unless they are close together.

With almost half of college undergraduates engaging in friends with benefits relationships (FWBRs), the current study sought to explore the sexual decision making strategies and potential physical and psychological health outcomes behind these relationships.

Using self-report measures, Study 1 asked 207 undergraduates to rate the importance of motivations, maintenance rules, and future outcomes of FWBRs in their own personal experience and for other men and women. Study 2 sampled 142 undergraduate women who were asked to indicate the percentage of time they engaged in sexual behavior under the influence of alcohol or marijuana and the frequency with which they used safe sex practices in an FWBR.

Both genders appeared equally motivated to begin an FWBR; however women reported establishing permanence rules and avoiding over-attachment in the relationship as significantly more important than men. Men were more likely to prefer that the FWBR remain unchanged, however both genders agreed that a transition to a committed relationship was unlikely. Alcohol use was not significantly more prevalent in an FWBR, nor was the likelihood of practicing safe sex.

Both studies employed the use of self-report surveys from a single university and were subject to social desirability.

Quantitatively examining young adults’ reasoning behind choosing to engage in FWBRs provided insight into their overarching fear of “being hurt” and their preference for “easy access” to sexual experiences. These trends may suggest a shift in dating patterns and a preference for avoiding the emotional complexities of a committed, monogamous relationship.

When subordinates violate a policy, authority figures have to decide whether to be strict and make them face the consequences or be lenient and not enforce the policy. In this chapter, we argue that when an authority figure treats a subordinate leniently, that subordinate is more likely to develop an elevated sense of entitlement, which then has various negative consequences for the authority figure and the subordinate’s group members. Drawing on the literature on the sources and consequences of psychological entitlement, we put forward propositions relating to authority leniency and subordinate entitlement. In summary, we propose (a) that single acts of leniency may lead subordinates to feel entitled to future leniency, (b) that repeated leniency may lead subordinates to develop a general sense of entitlement, and (c) that leniency and the resulting entitlement can have many negative consequences such as increasing group conflict and causing low performance. We report preliminary results in support of some propositions. For example, we show that leniency that can be attributed to something external to the subordinate may prevent the subordinate from feeling entitled. Last, we call for additional research. We hope that our chapter will cause authority figures to consider the consequences of treating subordinates leniently, including the possibility that the subordinates will subsequently feel entitled.

The present chapter throws light on the famous and very important issue of using eco-friendly, pollution free technology, named as ‘green technology’ or ‘green capital’ by developing economies in the sphere of environmental economics by using general equilibrium framework and tries to examine its impact on different polluting and non-polluting sectors of the economy. The present chapter has done so by using the concepts of ‘regime change’ and ‘endogenised green capital’ – these are the unique features of this work. Here, the authors have come across interesting outcomes by encompassing trade liberalisation in the form of international green capital immobility and international green capital mobility and it leads to an expansion of the sector that utilises it.
