Abstract
Purpose
The purpose of this paper is to provide an overview of the design and experimental work of compliant wing and wingtip morphing devices conducted within the EU FP7 project NOVEMOR and to demonstrate that the optimization tools developed can be used to synthesize compliant morphing devices.
Design/methodology/approach
The compliant morphing devices were “designed-through-optimization”, with the optimization algorithms including Simplex optimization for composite compliant skin design, aerodynamic shape optimization able to take into account the structural behaviour of the morphing skin, continuum-based and load path representation topology optimization methods and multi-objective optimization coupled with genetic algorithm for compliant internal substructure design. Low-speed subsonic wind tunnel testing was performed as an effective means of demonstrating proof-of-concept.
Findings
It was found that the optimization tools could be successfully implemented in the manufacture and testing stage. Preliminary insight into the performance of the compliant structure has been made during the first wind tunnel tests.
Practical implications
The tools in this work further the development of morphing structures, which when implemented in aircraft have potential implications to environmentally friendlier aircrafts.
Originality/value
The key innovations in this paper include the development of a composite skin optimization tool for the design of highly 3D morphing wings and its ensuing manufacture process; the development of a continuum-based topology optimization tool for shape control design of compliant mechanisms considering the stiffness and displacement functions; the use of a superelastic material for the compliant mechanism; and wind tunnel validation of morphing wing devices based on compliant structure technology.

Abstract
Outlines the underlying rationale for the North American Free Trade Agreement (NAFTA) between Canada, Mexico and the USA; and evaluates its impact from 1987 to 2000. Examines statistics on trade between the three countries and discusses changes in trade patterns and growth rates, providing a breakdown of US exports by state and industry. Shows an improved pattern and volume of trade, considers the impact on employment and admits that assessment of NAFTA’s costs and benefits is difficult. Sees Mexico as its main beneficiary so far, but predicts that this will change in the long run.

Abstract
Purpose
The purpose of this computational fluid dynamics (CFD) study is to give insight about the influence of the piston bowl geometry and the fuel ignition features on the resonance of direct injection diesel engines combustion chambers in order to provide support to the experimental findings on combustion noise.
Design/methodology/approach
The resonance due to the burned gases oscillations in a diesel combustion chamber is caused by the sudden rise in pressure due to the initial ignition of the air‐fuel mixture, and leads to the resonance noise. In the CFD study presented here the excitation source is represented by imposing locally in a small area (excitation zone) the pressure and temperature gradients of the start of combustion. The CFD approach is first validated against the acoustic modal theory. A parametric study representing different ignition conditions is then performed with a real bowl geometry.
Findings
The solutions obtained are analysed in terms of the energy of resonance (ER) and the response in the frequency domain. It was found that the response in frequency only varies with the diameter of the bowl, while the ER varies significantly in function of the injection conditions.
Research limitations/implications
These first conclusions need to be verified on the one hand by taking into account the piston motion, and, on the other hand, by modelling in a more realistic way the combustion excitation.
Practical implications
This CFD study has brought some insight into the flow phenomena that affect the resonance modes of a combustion chamber.
Originality/value
This CFD study uses a novel methodology to model the effect of the combustion excitation on the resonance modes of a combustion chamber.

Abstract
Purpose
Interest in reverse innovation (RI) is increasing. According to the authors’ review, more than 350 reliable sources (scientific publications, academic books and working papers) examine or at least discuss the concept. As RI gains popularity among academic authors, some discrepancies have started to appear. This wealth of publications could impact prior advancements related to understanding of the phenomenon. The purpose of this paper is to decrease fragmentation and focus on identifying and understanding RI.
Design/methodology/approach
A systematic review of RI was conducted. The review conformed to a rigorous set of core principles: it was systematic (organized according to a method designed to address the review questions), transparent (explicitly stated), reproducible and updatable, and synthesized (summarized the evidence relating to the review question).
Findings
This systematic review provides an improved theoretical and practical framework for the concept of RI. In terms of theory, the authors have demonstrated that the idea behind the concept is not entirely new. A consensus on the definition of RI is not reached in the literature, and descriptions in organizational theory contexts are sometimes misleading. The authors analyzed all the various definitions provided in the literature. From a practical point of view, the authors have explained the academic interest in RI in relation to organizational strategy, in particular the context in which strategies are adopted. The concept of RI has significant managerial implications, and the authors have proposed a conceptual framework to help managers understand and grasp the implications of RI. Finally, the authors have provided suggestions for future research on RI.
Originality/value
To the best of the authors’ knowledge, this is the first exhaustive literature review on RI.

This paper aims to examine whether agency costs predict disciplinary takeover likelihood for the UK listed companies between 1986 and 2015.
Abstract
Purpose
This paper aims to examine whether agency costs predict disciplinary takeover likelihood for the UK listed companies between 1986 and 2015.
Design/methodology/approach
Using survival analysis, the approach is to identify candidates for disciplinary takeover on the basis of Tobin’s Q (TQ), which is consistent with the approach advocated by Manne (1965). This study then examines how indicators of agency costs affect takeover likelihood within the set of disciplinary candidates.
Findings
This paper provides evidence of the effectiveness of TQ, rather than excess return, in identifying disciplinary takeover candidates. Takeover hazard for disciplinary candidates is higher for companies with higher levels of asset utilization and sales growth in particular. Companies with stronger agency problems are relatively less susceptible to disciplinary takeover.
Practical implications
Given the UK context of the study, where anti-takeover provisions are disallowed and when compared to findings of US studies, the results imply some support for the effectiveness of an open merger policy.
Originality/value
While the connection between takeover likelihood and the market for corporate control has been made in previous studies, the study adopts a more explicit agency theory framework than previous studies of takeover likelihood. A key component of the contribution follows from differentiating candidates for disciplinary takeovers from other forms of mergers and acquisitions.

Abstract
Purpose
This study seeks to: (1) discuss how the integrated reporting (IR) framework may provide the principles, concepts and the key elements to support the analysis and representation of circular economy (CE)–related activities and information; (2) explore how and to what extent current IR practices are including and disclosing CE-related information; (3) investigate through an exploratory case study the interplays between IR and CE.
Design/methodology/approach
Building on a theoretical analysis of the interplays between CE and IR, this study first performs textual content analysis on a dataset of 84 integrated reports to determine the type and extent of CE-related disclosure. Subsequently, the article presents and discusses an exploratory case study developed according to an action research perspective.
Findings
Through textual content analysis, the study provides data on CE-related reporting practices for 74 organizations operating worldwide, highlighting differences in reporting choices and emphasizing the role played by IR concepts. Through the exploratory case study, this article provides insights on how IR principles support the analysis and the (re)presentation of CE-related information.
Research limitations/implications
Content analysis is used to explore how and to what extent companies disclose CE-related information, not to investigate the quality of such disclosure. Only one single exploratory case study is used.
Practical implications
This article advocates to embed CE data into integrated reports and according to IR principles. The exploratory case study offers useful insights and examples.
Originality/value
This work represents one of the first studies advocating and exploring the interplays between CE and IR. Additionally, this study aids in the development of a more standardized and established terminology for CE research and reporting practices.

Abstract
Purpose
This study aims to develop theory on the process toward digital service innovation (DSI) and to generate insights into how companies deal with the rising complexity associated with DSI, both inside and outside of the organization, through organizational learning and alignment.
Design/methodology/approach
After purposeful sampling, in-depth, longitudinal case studies of three manufacturers are presented as illustration. Per case, multiple semi-structured interviews are conducted, and insights are validated through rich additional data gathering. Each company's DSI pathway is reconstructed with critical incident technique. Next, using systematic combining, a middle-range theory is developed by proposing a theoretical frame concerning the relations between DSI maturity, learning and alignment.
Findings
The authors posit that, as companies gradually develop and progress toward DSI maturity, they deal with a rising degree of complexity, fueling their learning needs. Companies that are apt to learn, pass through multiple cycles of learning and alignment to overcome specific complexities associated with different DSI stages, with each cycle unlocking new DSI opportunities and challenges.
Originality/value
The study applies a stage-based view on DSI combined with complexity management and organizational learning and alignment theory. It offers a theoretical frame and propositions to be used by researchers for future DSI studies and by managers to evaluate alternative DSI strategies and implementation steps.

Abstract
Purpose
The purpose of this paper is to examine the impacts of university and construction industry collaborations (UIC) activities in developing the employability of built environment graduates.
Design/methodology/approach
This study adopted a quantitative approach wherein data was obtained from professionals across academia, construction industry and government establishment within the South African built environment. A total of 204 questionnaires were administered to these professionals to provide information regarding the subject matter under question. Structural equation modeling (SEM) was adopted to examine possible relationships among identified factors that were obtained from a review of extant literature. SEM was performed using analysis of moment structures (AMOS Graphics, version 26) in testing the model and a best-fit was achieved after various model selections and validation tests were conducted.
Findings
The final model revealed that graduate employability can be improved through UIC as effective university-industry linkages provide students with mentoring opportunities and exposure to relevant training which improves their job market prospects and ultimately increases their professional relevance in the long run.
Practical implications
To continuously enhance the employability of students before graduation, universities are required to foster collaborations with the industry as such linkages are critical to the development of the future custodians of the construction industry.
Originality/value
There have been several generalized statements as to which of the UIC activities contribute to graduate employability. Therefore, through the use of SEM using AMOS, it was possible to state precisely the UIC constructs that are statistically significant and contribute to graduate employability.

Abstract
Qualität — verstanden als Markenzeichen für ein optimales Wirkungsresultat des Tourismus in Wirtschaft, Gesellschaft und Natur — wird für die ehemaligen Ostblockländer vielfach ganz global als kaum vorhanden und erst in weiter Feme in breitem Maße realisierbar angesehen. Am Beispiel von Ostdeutschland soll der Frage nachgegangen werden, welche Position gegenwärtig in diesem Prozeß tourismuspolitisch bestimmend ist.
