Applications of surrogate-assisted and multi-fidelity multi-objective optimization algorithms to simulation-based aerodynamic design
Authors: Amrit Anand , Leifsson Leifur 
Published: August 2019

Purpose
The purpose of this work is to apply and compare surrogate-assisted and multi-fidelity, multi-objective optimization (MOO) algorithms to simulation-based aerodynamic design exploration.

Design/methodology/approach
The three algorithms for multi-objective aerodynamic optimization compared in this work are the combination of evolutionary algorithms, design space reduction and surrogate models, the multi-fidelity point-by-point Pareto set identification and the multi-fidelity sequential domain patching (SDP) Pareto set identification. The algorithms are applied to three cases, namely, an analytical test case, the design of transonic airfoil shapes and the design of subsonic wing shapes, and are evaluated based on the resulting best possible trade-offs and the computational overhead.

Findings
The results show that all three algorithms yield comparable best possible trade-offs for all the test cases. For the aerodynamic test cases, the multi-fidelity Pareto set identification algorithms outperform the surrogate-assisted evolutionary algorithm by up to 50 per cent in terms of cost. Furthermore, the point-by-point algorithm is around 27 per cent more efficient than the SDP algorithm.

Originality/value
The novelty of this work includes the first applications of the SDP algorithm to multi-fidelity aerodynamic design exploration, the first comparison of these multi-fidelity MOO algorithms and new results of a complex simulation-based multi-objective aerodynamic design of subsonic wing shapes involving two conflicting criteria, several nonlinear constraints and over ten design variables.
Does selection of productivity estimation techniques matter?
Authors: Singh Awadhesh Pratap , Sharma Chandan 
Published: August 2019

Purpose
The purpose of this paper is to compare and analyze the modern productivity estimation techniques, namely, Levinsohn and Petrin (LP, 2003), Ackerberg Caves and Frazer (ACF, 2006), Wooldridge (2009) and Mollisi and Rovigatti (MR, 2017) on unit-level data of 32 Indian industries for the period 2009-2015.

Design/methodology/approach
The paper first analyzes different issues encountered in total factor productivity (TFP) measurement. It then categorizes the productivity estimation techniques into three logical generations, namely, traditional, new and advanced. Next, it selects four contemporary estimation techniques, computes the industrial TFP for Indian states by using them and investigates their empirical outcomes. The paper also performs the robustness check to ascertain, which estimation technique is more robust.

Findings
The result indicates that the TFP growth of Indian industries have differed greatly over this seven-years of period, but the estimates are sensitive to the techniques used. Further results suggest that ACF and Wooldridge yield the consistent outcomes as compared to LP and MR. The robustness test confirms Wooldridge to be the most robust contemporary technique for productivity estimation followed by ACF and LP.

Originality/value
To the authors’ knowledge, this is the first study that compares the contemporary productivity estimation techniques. In this backdrop, this paper offers two novelties. First, it uses advanced production estimation techniques to compute TFP of 32 diverse industries of an emerging economy: India. Second, it addresses the fitment of estimation techniques by drawing a comparison and by conducting a robustness test, hence, contributing to the limited literature on comparing contemporary productivity estimation techniques.
Beyond accessibility: empowering mobility-impaired customers with motivation differentiation
Authors: Zhang Ye , Gao Jie , Cole Shu Tian , Ricci Peter 
Published: August 2019

PurposeTo sufficiently fulfill the travel potential of people with mobility impairments (PwMIs), this study aims to propose a valuable supplement to facility/service accommodation by hospitality/tourism businesses by identifying and purposefully cultivating the superior motivation types for empowering PwMI’s travel pursuits despite challenges. To this end, the study proposes a self-determined versus controlled motivation subdivision to the predominant travel motivation typologies, with its practical value, theoretical value and application feasibility verified.Design/methodology/approachTo ensure the verification reliability across challenge travels, the study adopts an extreme groups design for data collection. Qualtrics surveys situated in two resort-package scenarios contrast in facility/service accommodation levels are paired with two US PwMI groups contrast in travel capabilities. An unconventional mix of analytical information and seemingly unrelated regressions are adopted for data analyses.FindingsSelf-determined motivations are found as the superior facilitators of PwMI’s challenging resort-travel pursuits, confirming the practical value of the proposed motivation subdivision. The theoretical value is verified given the subdivision’s significant explanatory power for resort-travel attitude and behavioral intentions, after controlling for travel purpose fulfillment. It is also feasible to achieve the targeted cultivation of self-determined motivations by supporting the basic physiological needs of autonomy, competence and relatedness.Practical implicationsThe study’s context-based findings on the effective motivational mechanisms for PwMI can guide hospitality/tourism businesses to improve PwMI-targeted marketing effectiveness and efficiency.Originality/valueKey theoretical contributions include expanding the explanatory power of travel motivation typologies, enhanced integration of self-determination theory into travel motivation conceptualization and more accurate reflection of the widespread presence of social factors in travel motivations.

Vision guided geometric regulation of PTC frame structures
Authors: Sun Peng , Lu Naiguang , Dong Mingli , Lou Xiaoping , Tan Zexiang 
Published: August 2019

Purpose
Geometric structure error of parabolic trough concentrator (PTC) frame affects the installation accuracy of mirrors and absorber tubes and thus decreases the solar energy concentrating efficiency. Until now, there is no effective method to instruct the assembly and regulation of PTC frames. This paper aims to propose a vision guided method for fast and accurate regulation of mirror and absorber supports to improve the geometric quality of PTC frames.

Design/methodology/approach
The PTC frame support regulating system consists of a general-purpose online photogrammetry system, frame support measurement adaptors and data analyzing software. First, the positions and angles of all the supports are measured in real time by the online photogrammetric system. Then, the measured positions and angles are aligned to the design reference frame through the transformation calculated by an absorber position constrained nonlinear optimization so as to get the geometric errors and regulating amounts. Finally, a graduated pseudo-color-based visualization method is proposed to assist the manual or automated regulation of PTC frame supports in site.

Findings
The proposed method does not need to construct a reference system nor specify the rotation attitude of the PTC frame, and it is capable of conducting efficient and accurate regulation on PTC frame assembly line. The method is applied to manual regulation of a light type PTC frame structure. After regulation, the maximum position and angle errors of supports are reduced to less than 0.15 mm and 0.15° respectively and the intercept factor is increased to 97%, which meets the requirement for a qualified PTC concentrator.

Originality/value
To the authors’ knowledge, this paper is the first to propose a vision guided assembly or regulation method for PTC frame structures. The research uses online photogrammetry system to provide real-time geometric quality information feedback, elaborates the data analysis algorithm and provides the visualization method for accurate and efficient in site regulation. Furthermore, this paper also provides theories, methods and experiences for other applications that use vision guidance for attitude regulation and digital flexible assembly of large equipment.
Share or send and receive? The impact of team knowledge outflow/inflow with IT support on performance
Authors: Lee Junyeong , Min Jinyoung , Kwak Chanhee , Pee L.G. , Lee Heeseok 
Published: August 2019

PurposeAn organization can be understood as a knowledge network in which teams send and receive knowledge. Many studies have explored knowledge sharing across teams but did not consider the direction of knowledge flows (KF), specifically how the knowledge inflow (KIF) and knowledge outflow (KOF) can be induced and influence team activities differently. To fill this gap, this paper distinguishes between KIF and KOF, examines their antecedents and consequences and considers how KIF and KOF within a team moderate the relationship between antecedents and KF of a team.Design/methodology/approachThis study used structural equation model analysis of a sample of 341 individuals within 73 teams from four companies.FindingsThe results suggest that IT support is essential because it influences both KIF and KOF. However, only KOF has a significant effect on team performance suggesting that ambidexterity is not always necessary. In promoting KOF, increasing task interdependency is also effective. The effect of IT support varies with the level of KIF diversity.Originality/valueThe findings emphasize the importance of distinguishing KOF from KIF in a team’s knowledge network under the theoretical lens of ambidexterity. Identifying how IT support influences KF and how these flows separately affect team performance can provide useful insights into managing and facilitating KF in an organization.
A false image of health: how fake news and pseudo-facts spread in the health and beauty industry
Authors: de Regt Anouk , Montecchi Matteo , Lord Ferguson Sarah 
Published: August 2019

Purpose
Diffusion of fake news and pseudo-facts is becoming increasingly fast-paced and widespread, making it more difficult for the general public to separate reliable information from misleading content. The purpose of this article is to provide a more advanced understanding of the underlying processes that contribute to the spread of health- and beauty-related rumors and of the mechanisms that can mitigate the risks associated with the diffusion of fake news.

Design/methodology/approach
By adopting denialism as a conceptual lens, this article introduces a framework that aims to explain the mechanisms through which fake news and pseudo-facts propagate within the health and beauty industry. Three exemplary case studies situated within the context of the health and beauty industry reveal the persuasiveness of these principles and shed light on the diffusion of false and misleading information.

Findings
The following seven denialistic marketing tactics that contribute to diffusion of fake news can be identified: (1) promoting a socially accepted image; (2) associating brands with a healthy lifestyle; (3) use of experts; (4) working with celebrity influencers; (5) selectively using and omitting facts; (6) sponsoring research and pseudo-science; and (7)exploiting regulatory loopholes. Through a better understanding of how fake news spreads, brand managers can simultaneously improve the optics that surround their firms, promote sales organically and reinforce consumers’ trust toward the brand.

Originality/value
Within the wider context of the health and beauty industry, this article sets to explore the mechanisms through which fake news and pseudo-facts propagate and influence brands and consumers. The article offers several contributions not only to the emergent literature on fake news but also to the wider marketing and consumer behavior literature.
Strategic groups maps: review, synthesis, and guidelines
Authors: Meilich Ofer 
Published: August 2019

PurposeThe purpose of this paper is to review, integrate and extend the methods for constructing and interpreting a strategic groups map. A strategic groups map is a visualization tool for capturing the essence of the competitive landscape in an industry: extent of competition between and among strategic groups, mobility barriers, available niches, positioning and industry dynamics.Design/methodology/approachThis paper extends Porter’s (1980, pp. 152-155) original prescriptions by reviewing the research on strategic groups in the almost 40 years since Porter’s contribution and by amalgamation of practitioners’ uncodified practices.FindingsThe process for constructing a strategic groups map consists of five steps: first, define the industry; second, identify strategic characteristics that distinguish between groups; third, divide firms into groups; forth, select the two main dimensions of the map, and draw the map; and five, interpret the map. Specific instructions are provided for practitioners and academic researchers. Several examples of strategic groups maps illustrate this. Ways to interpret the maps are discussed, followed by limitations and conclusion.Originality/valueThough the topic of strategic groups has been widely researched since the 1980s, there has been very little done in the area of mapping these groups, leaving scholars of businesses and industries with few directions for constructing strategic groups maps. To fill this gap, a structured process for constructing and interpreting a strategic groups map is provided.

Published: August 2019

PurposeThe purpose of this study is to use role expectation theory to identify potential determinants of user voting avoidance on mobile social media.Design/methodology/approachData were collected through a survey of 602 WeChat users, and the proposed model was analysed using structural equation modelling.FindingsResults indicate that user voting avoidance was positively influenced by unfair competition, perceived inauthenticity, perceived information insecurity, over-consumption of renqing (a unique Chinese human relation) and organisation placement in the context of mobile social media.Originality/valueThis study illustrates mobile user voting avoidance from the perspective of role expectation theory and clarifies the importance of avoidance in current voting research.
The moderating effects of leverage and marketing intensity on alliance formation announcements
Authors: Chaudhuri Malika , Janney Jay , Calantone Roger J. 
Published: August 2019

PurposeMarch’s 1991 work on exploitation and exploration has been studied in many different industries. The purpose of this paper is to analyze signals emanating from exploration and exploitation alliances within the pharmaceutical industry context. Specifically, the authors explore market reactions to announcements of alliance formations based not only on alliance type but also in terms of their marketing intensity and leverage.Design/methodology/approachThe authors employ a two-stage event-study market model using a two-day event window (event days 0, +1), creating cumulative abnormal returns (CARs). In the second stage, the authors regress the CARs against an array of control and explanatory variables.FindingsFindings suggest that even though firm announcements of exploration and exploitation formations initially generate favorable market reactions, the former has a greater impact on CAR relative to the latter. Furthermore, leverage and marketing intensity moderate the relationship between firms’ alliance formation announcements and CARs generated. In particular, firms’ alliance formation announcements generate relatively greater market reactions at lower (higher) levels of the firm’s leverage (market intensity).Research limitations/implicationsEvent studies are valuable for gauging initial impressions of management action, but they are not meant to address long-term value creation. While market reactions suggest the likelihood of an alliance’s success or failure, managers also assess the risk to a firm’s financial health should the alliance fail. As a result, announcements that signal the firm has discretionary capabilities to ameliorate the effect of a failed alliance are better received.Originality/valueThis study is the first to analyze the stock market’s perception and valuation of different types of risk, classified by exploration vs exploitation alliances. The study also contributes to the literature by analyzing how investors use the information about a firm’s financial leverage and marketing activities to fine-tune their valuation of different types of risk-taking activities.
Relationship between job embeddedness and innovative work behaviour
Authors: Susomrith Pattanee , Amankwaa Albert 
Published: August 2019

PurposeThe purpose of this paper is to enable management decisions to develop innovation within an organisation by examining the relationship between job embeddedness (JE) and innovative work behaviour (IWB) while also considering the moderating effect of life satisfaction upon this relationship.Design/methodology/approachData were collected from 213 employees of small- and medium-sized organisations in Thailand. Confirmatory factor analysis was conducted to assess the reliability of the measures and validity of the constructs. Multiple regression and PROCESS Macro techniques were used to test the direct and moderation effects.FindingsThe two components of JE, organisational and community embeddedness, were found to positively predict IWB. Additionally, life satisfaction was found to moderate the relationship between organisational embeddedness and IWB, but not the relationship between community embeddedness and IWB. At low levels of life satisfaction, the JE and IWB relationship was non-existent.Practical implicationsOrganisations can potentially foster employee innovation by adopting strategies that seek to strengthen employee embeddedness in the organisation and in their community.Originality/valueStudies on the effect of JE on IWB, particularly in small and medium enterprises and the influence of life satisfaction is sparse. This study redresses this imbalance in the knowledge base.
A behavioral theory of patent application rhythm
Authors: Guo Bin , Ding Peng 
Published: August 2019

PurposePrevious studies employing the behavioral theory of the firm have not explicitly taken the roles of decision makers and corporate governance into consideration. The purpose of this paper is to fill in this gap by integrating CEO overconfidence and discretion into the performance feedback mechanism.Design/methodology/approachFinancial data were collected from 1,730 Chinese listed companies in the period 2011–2015. Firm-level patent application data were collected for 1988–2015 to measure firm patent application rhythm. Hypothesis testing relied on the fixed effect panel data model.FindingsThere is a positive relationship between performance discrepancy and a firm’s patent application rhythm. CEO overconfidence will weaken this positive relationship. The negative moderating effect of CEO overconfidence will be less pronounced when CEO discretion is high.Originality/valueTo the best of the authors’ knowledge, this work is the first empirical study that investigates the roles of CEO overconfidence and discretion in shaping the performance feedback mechanism.
Intellectual capital disclosure and academic rankings in European universities
Authors: Brusca Isabel , Cohen Sandra , Manes-Rossi Francesca , Nicolò Giuseppe 
Published: August 2019

Purpose
The purpose of this study is to compare of the way intellectual capital (IC) is disclosed in the websites of the universities in three European countries to assess the way universities decide to communicate IC to their stakeholders and identify potential patterns and trends. In addition, the relation between the level and the type of IC Web disclosure in universities and academic rankings as a proxy of performance is explored to reveal interrelations.

Design/methodology/approach
The study is based on a sample of 128 universities coming from Greece (22), Italy (58) and Spain (48). The websites of the universities are content-analysed to measure the level of IC disclosure. The IC disclosure metrics are then correlated with the academic rankings of the World Ranking.

Findings
While the level of IC disclosure among universities and among countries is not homogeneous, human capital and internal capital items are more heavily disclosed compared to external capital items in all three countries. In addition, larger universities in terms of number of students tend to disclose more on IC. Moreover, there is a positive correlation between the level of IC Web disclosure and the academic ranking that challenges the IC disclosure strategies followed by the universities.

Originality/value
The paper represents an innovative contribution to the existing literature as it investigates websites to assess the level of IC disclosure provided by universities in a comparative perspective. Furthermore, it analyses the relationship between the online IC disclosure and European universities’ academic rankings and provides evidence on the interaction between the IC disclosure and the ecosystem in which the universities operate contributing to the fourth stage of IC research.
