Fast identification of transonic buffet envelope using computational fluid dynamics
Authors: Drofelnik Jernej , Da Ronch Andrea , Franciolini Matteo , Crivellini Andrea 
Published: November 2018

Purpose
This paper aims to present a numerical method based on computational fluid dynamics that allows investigating the buffet envelope of reference equivalent wings at the equivalent cost of several two-dimensional, unsteady, turbulent flow analyses. The method bridges the gap between semi-empirical relations, generally dominant in the early phases of aircraft design, and three-dimensional turbulent flow analyses, characterised by high costs in analysis setups and prohibitive computing times.

Design/methodology/approach
Accuracy in the predictions and efficiency in the solution are two key aspects. Accuracy is maintained by solving a specialised form of the Reynolds-averaged Navier–Stokes equations valid for infinite-swept wing flows. Efficiency of the solution is reached by a novel implementation of the flow solver, as well as by combining solutions of different fidelity spatially.

Findings
Discovering the buffet envelope of a set of reference equivalent wings is accompanied with an estimate of the uncertainties in the numerical predictions. Just over 2,000 processor hours are needed if it is admissible to deal with an uncertainty of ±1.0° in the angle of attack at which buffet onset/offset occurs. Halving the uncertainty requires significantly more computing resources, close to a factor 200 compared with the larger uncertainty case.

Practical implications
To permit the use of the proposed method as a practical design tool in the conceptual/preliminary aircraft design phases, the method offers the designer with the ability to gauge the sensitivity of buffet on primary design variables, such as wing sweep angle and chord to thickness ratio.

Originality/value
The infinite-swept wing, unsteady Reynolds-averaged Navier–Stokes equations have been successfully applied, for the first time, to identify buffeting conditions. This demonstrates the adequateness of the proposed method in the conceptual/preliminary aircraft design phases.
Unsteady aerodynamic characteristics of a morphing wing
Authors: Xiang Jinwu , Liu Kai , Li Daochun , Cheng Chunxiao , Sha Enlai 
Published: November 2018

Purpose
The purpose of this paper is to investigate the unsteady aerodynamic characteristics in the deflection process of a morphing wing with flexible trailing edge, which is based on time-accurate solutions. The dynamic effect of deflection process on the aerodynamics of morphing wing was studied.

Design/methodology/approach
The computational fluid dynamic method and dynamic mesh combined with user-defined functions were used to simulate the continuous morphing of the flexible trailing edge. The steady aerodynamic characteristics of the morphing deflection and the conventional deflection were studied first. Then, the unsteady aerodynamic characteristics of the morphing wing were investigated as the trailing edge deflects at different rates.

Findings
The numerical results show that the transient lift coefficient in the deflection process is higher than that of the static case one in large angle of attack. The larger the deflection frequency is, the higher the transient lift coefficient will become. However, the situations are contrary in a small angle of attack. The periodic morphing of the trailing edge with small amplitude and high frequency can increase the lift coefficient after the stall angle.

Practical implications
The investigation can afford accurate aerodynamic information for the design of aircraft with the morphing wing technology, which has significant advantages in aerodynamic efficiency and control performance.

Originality/value
The dynamic effects of the deflection process of the morphing trailing edge on aerodynamics were studied. Furthermore, time-accurate solutions can fully explore the unsteady aerodynamics and pressure distribution of the morphing wing.

Technology roadmapping in security and defence foresight
Authors: Vicente Oliva Silvia , Martinez-Sanchez Angel 
Published: November 2018

PurposeThis paper aims to provide an analysis of Spanish Defence National Foresight Exercise.Design/methodology/approachThe analysis is based on a content analysis of public domain Spanish Defence National Foresight Exercise, and a study directed to analyse the impact on defence technological and industrial base.FindingsForesight studies on the defence and security environment uses hybrid methodologies, but rarely involve all the stakeholders, and specially the citizens. The authors place a particular emphasis on the impact of these defence and security foresight studies, and following policies to increase the competitiveness and advanced technologies in the future. The analysis of the Spanish contractors allows an evaluation of the roadmaps as a policy instrument for the industrial defence industry. The main challenges for the next exercises in the European countries are to increase the interest in the firms’ intelligence systems, and the participation and representation of citizens as a way to guarantee their rights. Therefore, a technology roadmap must be complemented with other more participative foresight methods.Originality/valueForesight studies on the defence and security environment have been the subject of very few systematic analyses of impact. This paper makes a contribution to such analysis.
Affective practices and the prison visit: learning at Port Arthur and the Cascades Female Factory
Authors: McKernan Amy 
Published: November 2018

Purpose
The purpose of this paper is to consider the ways Port Arthur Historic Site and the Cascades Female Factory educate visitors using the often contentious and confronting histories of convictism in Australia.

Design/methodology/approach
The research was conducted between 2012 and 2015, and included analysis of exhibitions and education programs at the two sites, as well as interviews with core staff, and archival research. Analysis employed a methodological framework drawing on Margaret Wetherell’s (2012) notion of “affective practice”, as well as understandings of historical thinking in education developed by theorists and educators.

Findings
The two sites take differing approaches to educating visitors about the “uncomfortable” histories related to their heritage. Ultimately, this paper argues that the Cascades presents a greater ease with communicating the confronting aspects of the site’s history, while Port Arthur’s interpretive strategies are often focussed on countering widespread assumptions about the “darkness” and cruelty characteristic of the penal system in Australia. Overall, the analysis finds considerable potential in the “use” of confronting and contested history in teaching aimed at developing historical thought and empathy.

Originality/value
The research addresses an issue that is of central concern in heritage education at present – interpretations of confronting and contentious histories – and employs an innovative set of conceptual strategies and tools to gather insights of use to practitioners in heritage and education.
They teach, but do they apply?
Authors: Petrusch Anete , Roehe Vaccaro Guilherme Luís , Luchese Juliane 
Published: November 2018

Purpose
Although discussed for more than 20 years, information about Lean adoption in higher education institutions (HEIs) is scarce, especially in developing countries. This research aims to investigate the degree of Lean thinking adoption on administrative services of Brazilian private HEIs. The results are compared to studies from USA and UK, highlighting the maturity on enablers, principles, tools and performance measures related to Lean.

Design/methodology/approach
A quantitative survey research was carried out. The instrument is adapted for HEIs from the proposal of Malmbrandt and Åhlström (2013) for Lean services. Cronbach’s alpha and factor analysis were used to validate the adapted instrument. Additional data analysis was based on non-parametric tests.

Findings
No evidence of broad implementation of Lean thinking in administrative processes of Brazilian private HEIs was found, with the adoption being incipient. The results are convergent to those presented by other studies in the USA and the UK. There is a gap between the existing knowledge about Lean in the academic sphere of the HEIs and its application on their academic processes.

Research limitations/implications
The effective sample size was of 47, despite contacts being sent to 2,090 institutions. This sample allows exploratory research, although further research is required. Results are adherent to those found in research from other countries.

Originality/value
The research presents descriptive and exploratory results regarding the adoption of Lean in Brazilian HEIs. No previous similar research was found in the literature.
Social media brand perceptions of millennials
Authors: Helal Guida , Ozuem Wilson , Lancaster Geoff 
Published: November 2018

PurposeA phenomenon that has revolutionized society is the technological millennial approach to communication. Social media has matured into a prime channel for regular interactions and development of brand–customer relationships that enrich a social identity. The purpose of this paper is to investigate how this affects business communications.Design/methodology/approachThe study utilized a social constructivist perspective, adopting an inductive and embedded case study strategy.FindingsDrawing on the social identity theory, this paper examines how evolving social media platforms have impacted on brand perceptions in the fashion apparel and accessories industries. Fashion brands’ online presence provide a platform for customers to supplement social identity based on associations with brands, and ultimately this can shape brand perceptions among customers through promised functional and symbolic benefits.Research limitations/implicationsThe paper investigates a specialized marketing activity in the UK. A broader internationally based study would add strength to these findings.Practical implicationsThe paper focuses on theoretical and managerial implications and proffers significant roles that social media and identity may play in keeping up with the design and development of marketing communications programs.Social implicationsMultinational corporations have embraced internet technologies and social media in adopting platforms that their brands can use to contribute content to followers.Originality/valueIn total, 30 potential participants, drawn from diverse backgrounds, were contacted via social networking sites, e-mails and telephone. In total, 22 agreed to participate and their mean age was 26. An open-ended questionnaire allowed for elaboration, providing appropriate responses for a second interviewing phase. Four industry professionals were recruited through the researchers’ personal networks to participate in in-depth interviews that sought to investigate the significance of social media as a marketing tool from an industry perspective.
Integrating the importance levels of friends into trust-based ant-colony recommender systems
Authors: Tengkiattrakul Phannakan , Maneeroj Saranya , Takasu Atsuhiro 
Published: November 2018

PurposeThis paper aims to propose a trust-based ant-colony recommender system. It achieves high accuracy and coverage by integrating the importance level of friends. This paper has two main contributions, namely, selecting higher-quality raters and improving the prediction step. From these two contributions, the proposed trust-based ant-colony recommender system could provide more accurate and wider-coverage prediction than existing systems.Design/methodology/approachTo obtain higher-quality raters, the data set was preprocessed, and then, trust values were calculated. The depth of search was increased to obtain higher coverage levels. This work also focuses on the importance level of friends in the system. Because the levels of influence on the active user of all friends are not equal, the importance level of friends is integrated into the system by transposing rater’s rating to the active user’s perspective and then assigning a weight to each rater.FindingsThe experimental evaluation clearly demonstrates that the proposed method achieves better results in terms of both accuracy and coverage than existing trust-based recommender systems. It was found that integrating the importance level of friends into the system, which transposes ratings and assigns weight to each user, can increase accuracy and coverage.Originality/valueExisting trust-based ant-colony recommender systems do not consider the importance level of friends in the prediction step. Most of them only focus on finding raters and then using the rater’s real ratings in the prediction step. A new method is proposed that integrates the importance level of friends into the system by transposing a rater’s rating to match the active user’s perspective and assigning a weight for each rater. The experimental evaluation demonstrates that the proposed method achieves better accuracy and coverage than existing systems.
Networked interdependencies and interaction in a biotechnology research project
Authors: Janusz Artur , Bednarek Agata , Komarowski Leszek , Boniecki Pawel , Engelseth Per 
Published: November 2018

Purpose
The purpose of this paper is to reveal the interdependencies involved and how interaction takes place in the context of a project organization as a network of academic and business actors.

Design/methodology/approach
This study focuses on relationships between business and academia and applies a single case research strategy. Data are collected through a series of theoretically sampled in-depth interviews including company observations. The single case study provides a rich narrative of the network structure and processes involved in establishing, implementing and completing a research project in Poland. The Industrial Marketing and Purchasing Group network approach focusing on resource combinations that emerge in a network structure characterized by interdependency and integration is applied to analyze interaction in this project-organized network.

Findings
Change in interdependencies, interaction and integration are analyzed individually, and in conclusion in relation to each other. While supply chain management literature postulates that integration is a management goal, a driver of successful business, this study points out that integration is an outcome of interaction in a context of changing interdependencies. This means that managerial focus should rather be driven to understanding the nature of network interdependencies, their path of change and how interaction is carried out in this emergent context.

Originality/value
The study aims to help better understand the potential for research project cooperation by explaining how businesses and research units can cooperate through an understanding that integration is a complex phenomenon, focusing on how management may better support services production through careful consideration of that integration is developed through considerations of interdependencies as context of interaction in the varied business cultures a project network comprises. Project management is more a learning process than a planning process.

Authors: Talpur Ashfaque Ahmed , Ryan Tony , Ali Parveen , Hinchliff Sharron 
Published: November 2018

PurposeThe purpose of this paper is to perform a review of the literature of empirical studies on elder mistreatment (EM) in South Asians, and to discuss key implications for policy, practice and research.Design/methodology/approachFor this review, multiple electronic databases in the international health and social science were searched and supplemented by grey literature and cross-references. Quality of papers was assessed by two authors against the standard checklists.FindingsIn total, 16 studies met the inclusion criteria of this review, of which 11 were cross-sectional design, and only six of them used standard instruments to measure EM. The prevalence estimates of overall EM retrieved from general population-based studies ranged from 9.3 per cent in India to 49.1 per cent in Nepal. Age, gender, residential settings, socioeconomic status, health, education, and social structures and processes were key risk factors for EM in South Asian communities. Reporting and action taking were culturally rooted.Originality/valueWhile the review is not systematic, there are limitations associated with the paper in covering the diverse range of databases and studies. However, this review provides a valuable synthesis of the empirical papers on the incidence, culturally specific risk factors and reporting trends of EM in South Asians. Additionally, the review presents the papers evaluated for a quality to ensure the validity of empirical data. Finally, the review includes several implications for policy, practice and future research on EM which may ultimately contribute in improving the health and wellbeing of elder South Asians.
Research on the relationship of the weaker enterprises post-merger brand strategy and consumers’ purchase intention
Authors: Yao Peng , Wang Xinxin 
Published: November 2018

PurposeNowadays, many weak brands have acquired strong international brands to accelerate their internationalization. However, “the weakers acquire the strongers” model of M&A leads to many consumers’ loss. The purpose of this paper is to explore the relationships between the brand strategy after the M&A, brand authenticity and consumer purchase intention through two experiments.Design/methodology/approachBuilding on an extensive literature review, the authors identify four hypotheses. Hypotheses were tested on data collected across 190 Chinese consumers.FindingsThe results show that the decline of consumer purchase intention was mainly caused by the falling consumer assesses on brand authenticity; the different post-merger brand strategies have significant difference on brand authenticity and consumer purchase intention, and self-brand connection played a moderate role between brand authenticity and consumer purchase intention.Originality/valueThe research reveals the reasons for consumer loss after mergers and acquisitions and provides empirical insights into how post-merger brand strategies can be manifested to convey brand authenticity as well as to build consumers’ purchase intention. In addition, the findings confirm the role of self-brand connection.

Authors: Ma Baolong , Cheng Feiyan , Bu Jingjing , Jiang Jiefan 
Published: November 2018

PurposeAlthough brand alliance has become quite ubiquitous in the marketplace and attracted considerable interest amongst researchers, little research has investigated its effects on the brand equity of partners. The purpose of this paper is to demonstrate why and how brand alliance affects the brand equity of the partners in an alliance.Design/methodology/approachThe hypotheses were tested by analysing the data of 260 participants in China, which were collected from an experiment.FindingsThis research draws five conclusions: the brand equity of a pre-alliance partner has a positive effect on brand alliance evaluation; product fit and brand fit amongst partners also have a positive effect on brand alliance evaluation; alliance brand evaluation has a positive impact on the brand equity of a post-alliance brand; the brand equity of a pre-alliance partner exerts a positive effect on the brand equity of a post-alliance partner; and the spillover effect of brand alliance for a weak brand is stronger than that of a strong brand in an asymmetrical brand alliance.Originality/valueThis research introduces brand equity into the field of brand alliance. From the perspective of consumer perception, the authors measure brand equity and provide insights for a company to effectively enhance brand equity through brand alliance. The authors explore ways to increase the brand equity of partners through brand alliance. Additionally, the authors discuss the spillover effects of the brand equity of partners in symmetric and asymmetric brand alliances.
Global human resources: a key to mission accomplishment
Authors: Wan Hooi Lai 
Published: November 2018

PurposeThe purpose of this paper is to explore the factors needed for the development of global human resources for leadership assignments in foreign subsidiaries. The paper aims to find an answer to enhance expatriate mission accomplishment rate at subsidiaries abroad.Design/methodology/approachThis study examines the development of global human resources. In-depth face-to-face interviews were employed to collect data from eight senior HR managers in three financial institutions in Taiwan, while data from 28 expatriates in the overseas subsidiaries were obtained from asynchronous e-mail interviews. Conventional content analysis was used to code categories directly from the data.FindingsThe results of the study revealed that organizational policies do not focus on developing global human resources. To portray a global image, the focus is on staffing overseas subsidiaries with foreigners and Taiwanese that can speak English. Development to prepare staff for expatriation is limited to pre-departure training that focused mainly on language and cultural awareness training. However, organizational support during expatriation and repatriation is important. Expatriates view security briefing crucial and familiarization visit helps them to decide whether or not to accept expatriation. Organizational policies favor those that were not expatriated in terms of career progression deter managers from accepting international assignments.Originality/valueIt highlights some best practices in developing global human resources taking into consideration the herd mentality and social perspective. Social support, social learning and social capital are instrumental in developing global human resources as these hasten cultural adjustment.
