Abstract
Purpose
This paper aims to present a computational aeroelastic capability based on a fluid–structure interaction (FSI) methodology and validate it using the NASA Common Research Model (CRM). Focus is placed on the effect of the wind tunnel model structural features on the static aeroelastic deformations.
Design/methodology/approach
The FSI methodology couples high-fidelity computational fluid dynamics to a simplified beam representation of the finite element model. Beam models of the detailed CRM wind tunnel model and a simplified CRM model are generated. The correlation between the numerical simulations and wind tunnel data for varying angles of attack is analysed and the influence of the model structure on the static aeroelastic deformation and aerodynamics is studied.
Findings
The FSI results follow closely the general trend of the experimental data, showing the importance of considering structural model deformations in the aerodynamic simulations. A thorough examination of the results reveals that it is not unequivocal that the fine details of the structural model are important in the aeroelastic predictions.
Research limitations/implications
The influence of some changes in structural deformation on transonic wing aerodynamics appears to be complex and non-linear in nature and should be subject to further investigations.
Originality/value
It is shown that the use of a beam model in the FSI approach provides a reliable alternative to the more costly coupling with the full FE model. It also highlights the non-necessity to develop precise, detailed structural models for accurate FSI simulations.

Abstract
Purpose
The purpose of this paper is to better understand the factors that may improve or hinder the impact of sport for development and peace projects. Sport for development and/or peace (SDP) has been described as an emerging, yet under-theorized research field (Schnitzer et al., 2013). As such, few authors have analyzed the conditions, best practices and processes needed for achieving impact on context through SDP. The purpose of this paper is to address this gap in current knowledge.
Design/methodology/approach
A literature review was chosen to analyze the focus and findings of the related body of work.
Findings
A conceptual model of the dominant SDP process serves as a framework to identify and analyze concepts that may influence SDP impact on context. Moreover, this conceptual model provides insight about an apparent empirical incongruity between the theoretical and practical impact of this dominant SDP process on the ground.
Practical implications
This paper opens a debate around the process currently deployed by SDP agencies to influence peace and/or development. Specifically, we question if indoctrinating sport-related values into child athletes, who then somehow influence their communities, is the most cost effective process for sport to contribute to development and/or peace.
Originality/value
This paper addresses the paucity of insight about concepts that SDP agencies should implement to impact context. This contribution appears significant in a context of increased competition for funding. As growing number of SDP agencies operating in emerging markets compete for rarifying corporate funding, deploying cost-effective projects for development and peace may provide SDP agencies with a competitive advantage.

Abstract
Synopsis
Ian Henson was about to take the biggest financial risk of his life. He had just agreed to purchase three Booster Juice franchise stores in Kamloops, British Columbia, Canada. Henson knew that transitioning leadership at companies was a difficult task, and he was aware that he was replacing a popular leader: Natalie Peace. Compounding the challenge ahead of Henson were two major hurdles, the first was demographic in nature: Booster Juice’s employee group was young (on average below 20 years old) and many adored Peace, he was certain that whoever replaced her would have a difficult transition. The second challenge was managing change: Henson needed to cut costs. Peace had several generous policies that Henson needed to consider altering or removing, a potentially unpopular task. Initially, this case puts students in Henson’s shoes: How should he handle the specific aspects of this leadership transition? It allows professors to examine the broader issue of managing a change process.
Research methodology
Data for the case were collected from various sources. Public records, historical documents, and media reports were the main source for general background information and context. Primary data were collected through a series of interviews with the present and past owners of the Booster Juice franchises discussed.
Relevant courses and levels
This case was developed for use in an undergraduate management course or where change management and leadership are specific modules, an organization behavior class is a good example of where the case should fit. The objective of the case is to illustrate the challenges that resulted from a change in leadership and examine how to manage the change process. The thought-provoking element in this case is the leaders involved have very different leadership styles. The authors anticipate this case would be one used early in the course, as it is concise and straightforward to read, and clearly illustrates the issues to be examined. It provides an effective tool through which to introduce students to change management and styles of leadership. The added value is that the case is based on a company built by an undergraduate student and thus students tend to be very interested in the business itself.
Theoretical bases
The main theoretical base for the case is based on change management and exemplary leadership. To facilitate this the authors use Kurt Lewin’s models of change, Kotter’s eight step process, specifically referring to Kotter (1995). The authors then use Kouzes & Psoner five practices of exemplary leadership, referring to Kouzes, and Posner (2003). The authors specifically reference Northouse (2010).

Abstract
Purpose
The purpuse of this study is to answer the following two questions. Do conflict management efforts mitigate the recurrence and severity of civil conflict? If so, how? Do some conflict management strategies fare better than others in these tasks? This study theorizes about the connection between the costliness of a conflict management strategy – with respect to both the disputants and third parties – and civil conflict outcomes. This theory produces two contradictory predictions: that more costly strategies either increase or decrease violence. This study not only adjudicates between these two possibilities but also incorporates the role of timing. The early use of more costly strategies, for example, may encourage disputants to reduce violence in civil conflicts.
Design/methodology/approach
To evaluate the predications that the authors derive from their theoretical argument, the authors quantitatively analyze the effect of conflict management strategies’ relative cost on various measures of civil conflict recurrence and severity. The authors first identify the set of international–civil militarized conflicts (I-CMCs) during the period 1946–2010. I-CMCs contain two dimensions – interstate and intrastate – making them the most complex and dangerous form of militarized conflict. To each I-CMC, the authors then link all third-party attempts to manage the I-CMC’s civil conflict dimension. Finally, after developing quantitative indicators, a series of regression equations explore the relationships of primary interest.
Findings
Two main findings emerge. First, when third parties use a relatively more costly conflict management strategy to manage a civil conflict (e.g. a peace operation or military intervention, as opposed to mediation), the severity of the conflict increases, while conflict recurrence rates remain unchanged. Second, this study uncovers a trade-off. The early use of a relatively more costly management strategy lowers a civil conflict’s severity in the short-term. It also, however, increases the likelihood – and speed with which – civil conflict recurs. The timing of certain conflict management strategies matters.
Originality/value
Scholars typically isolate conflict management strategies in number (i.e. consider efforts as independent of one another, even those within the same conflict) and kind (i.e. examine mediation but not peace operations). This study, in contrast, includes the following: the full menu of conflict management strategies available to third parties – negotiation, mediation, adjudication/arbitration, peace operations, sanctions and military intervention – over a lengthy time period (1946–2010); theorizes about the relative merits of these strategies; and considers the timing of certain conflict management efforts. In so doing, it highlights a policy trade-off and proposes promising areas for future research.

Abstract
Purpose
The purpose of this paper is to understand the implicit motivations of entrepreneurial philanthropists during different stages of their lives.
Design/methodology/approach
The authors follow a Historical Organization Studies approach by performing a psychobiographical analysis using McClelland’s Thematic Apperception Test on the autobiography of Andrew Carnegie across different stages of his life while considering the historical context.
Findings
The configuration of the implicit motivations of entrepreneurial philanthropists change with achievement motivation decreasing and power motivation increasing over time explaining the shift of focus from self to others.
Originality/value
While researchers have been theorizing and using interviews to uncover shifts in entrepreneurial motivations, this is the first paper to longitudinally uncover implicit motivations to explain why successful entrepreneurs give back later in life.

Abstract
Purpose
To outline strategies for balancing a critical approach to sport for development and peace (SDP) interventions with approaches that highlight the potentially positive outcomes of SDP. Two examples of attempts to balance these approaches are highlighted. One is a critical analysis of responses to sport-related environmental problems. The other is a study of how a sport-related reconciliation event led by celebrity athletes was successfully organized.
Design/methodology/approach
In the first part of the chapter, the complexity of the SDP concept (and the terms sport, peace, and development) is discussed along with the challenges of negotiating critical and more optimistic stances on SDP. In the second part, two approaches to navigating between “extremely critical” and “unwaveringly optimistic” stances on SDP are outlined through two case studies.
Findings
The two case studies are described along with preliminary findings from studies that were conducted. Each case study is accompanied by a discussion of how the author “middle-walked” between “extremely critical” and “unwaveringly optimistic” positions on SDP. A focus in this section is on how theory, methods, and strategies for reporting findings were accounted for in the process of balancing these distinct positions.
Research limitations/implications
The difficulties attempting to balance critical and optimistic positions are discussed. The difficulties connecting critical analysis with practical suggestions for improving SDP-related work were also outlined.
