Bio-inspired optimization of leading edge slat
Authors: Raj Mohamed Mohamed Arif , Kumar Reddy Ketu Satish , Sai Sri Vishnu Somaraju 
Published: December 2022

Purpose
The high lift devices are effective at high angle of attack to increase the coefficient of lift by increasing the camber. But it affects the low angle of attack aerodynamic performance by increasing the drag. Hence, they have made as a movable device to deploy only at high angles of attack, which increases the design and installation complexities. This study aims to focus on the comparison of aerodynamic efficiency of different conventional leading edge (LE) slat configurations with simple fixed bioinspired slat design.

Design/methodology/approach
This research analyzes the effect of LE slat on aerodynamic performance of CLARK Y airfoil at low and high angles of attack. Different geometrical parameters such as slat chord, cutoff, gap, width and depth of LE slat have been considered for the analysis.

Findings
It has been found that the LE slat configuration with slat chord 30% of airfoil chord, forward extension 8% of chord, dip 3% of chord and gap 0.75% of chord gives higher aerodynamic efficiency (Cl/Cd) than other LE slat configurations, but it affects the low angles of attack aerodynamic performance with the deployed condition. Hence, this optimum slat configuration is further modified by closing the gap between LE slat and the main airfoil, which is inspired by the marine mammal’s nose. Thus increases the coefficient of lift at high angles of attack due to better acceleration over the airfoil nose and as well enhances the aerodynamic efficiency at low angles of attack.

Research limitations/implications
The two-dimensional computational analysis has been done for different LE slat’s geometrical parameters at low subsonic speed.

Practical implications
This bio-inspired nose design improves aerodynamic performance and increases the structural strength of aircraft wing compared to the conventional LE slat. This fixed design avoids the complex design and installation difficulties of conventional movable slats.

Social implications
The findings will have significant impact on the fields of aircraft wing and wind turbine designs, which reduces the design and manufacturing complexities.

Originality/value
Different conventional slat configurations have been analyzed and compared with a simple fixed bioinspired slat nose design at low subsonic speed.

Authors: Behera Rajat Kumar , Bala Pradip Kumar , Panigrahi Prabin Kumar , Rana Nripendra P. 
Published: December 2022

PurposeCoronavirus disease (COVID-19) was declared as a pandemic since COVID-19's widespread outbreak and the hospitality industry has been the hardest hit due to lockdown. Consequently, hospitality workers are suffering from the negative aspects of mental health. In the event of such a crisis, this study aims to explore the link between unemployment and home isolation to the willingness to choose electronic consultation (e-consultation) by exploiting psychological ill-being and behavioural intention (BI) with marital status as a moderator.Design/methodology/approachA quantitative methodology is applied to primary data collected from 310 workers from the hospitality industry through an online survey.FindingsFindings of this study suggest that the usage of the e-consultation service can be adopted using three levels. There are valid reasons to conclude unemployment and home isolation are linked to higher rates of psychological health behaviours, which can result in stigma, loss of self-worth and increased mortality. The adverse effect is higher for single individuals than for married people.Originality/valueThe study focussed on e-consultation, BI coupled with the Fishbein scale and a classification model for the prediction of willingness to choose e-consultation with the extension of Theory of Planned Behaviour (TPB).
A numerical study of mist-air film cooling on a 3-D flat plate
Authors: M.V.V. Srinivas , Hari Surya Mudragada , Singh Devendra Pratap , Biswal Pratibha , Reddy Sathi Rajesh 
Published: December 2022

Purpose
The purpose of this study is to explore the mist-air film cooling performance on a three-dimensional (3-D) flat plate. In mist-air film cooling technique, a small amount of water droplets is injected along with the coolant air. The objective is to study the influence of shape of the coolant hole and operating conditions on the cooling effectiveness.

Design/methodology/approach
In this study, 3-D numerical simulations are performed. To simulate the mist-air film cooling over a flat plate, air is considered as a continuous phase and mist is considered as a discrete phase. Turbulence in the flow is accounted using Reynolds averaged Navier–Stokes equation and is modeled using k–e model with enhanced wall treatment.

Findings
The results of this study show that, for cylindrical coolant hole, coolant with 5% mist concentration is not effective for mainstream temperatures above 600 K, whereas for fan-shaped hole, even 2% mist concentration has shown significant impact on cooling effectiveness for temperatures up to 1,000 K. For given mist-air coolant flow conditions, different trend in effectiveness is observed for cylindrical and fan-shaped coolant hole with respect to main stream temperature.

Research limitations/implications
This study is limited to a flat plate geometry with single coolant hole.

Practical implications
The motivation of this study comes from the requirement of high efficiency cooling techniques for cooling of gas turbine blades. This study aims to study the performance of mist-air film cooling at different geometric and operating conditions.

Originality/value
The originality of this study lies in studying the effect of parameters such as mist concentration, droplet size and blowing ratio on cooling performance, particularly at high mainstream temperatures. In addition, a systematic performance comparison is presented between the cylindrical and fan-shaped cooling hole geometries.
Modelling aileron and spoiler deflections with the linear frequency domain method (LFD) for subsonic flight conditions
Authors: Govindan Kuharaaj , Bier Niko 
Published: December 2022

Purpose
This study aims to predict dynamic responses of aileron and spoiler control surfaces in subsonic flight via the use of surrogate models. The prepared reduced order models prove useful when quick estimations for a large number of variations are required.

Design/methodology/approach
The linear frequency domain (LFD) method was used for the simulation study. Each surrogate contained a database of 100 control surface dynamic responses over a spectrum of 200 harmonics computed with LFD. To interpolate new results, the DLR surrogate modelling toolbox, SMARTy, was used. The database’s samples were prepared in a Halton sequence, making interpolation reliable. The surrogate’s parameter space was the Mach number, Reynold’s number, angle of attack, control surface deflection angle and the control surface chord length.

Findings
The LFD method proved effective for the mentioned purpose: the surrogates were accurate, up to 15% of relative error, in reproducing dynamic responses of aileron and spoiler deflections at low speed, within the limitations of flow field linearity, as well as surrogate prediction capability. The restrictions of the surrogate, and the reasoning thereof, are also presented in detail in the study. Future load alleviation studies are a potential of the findings here.

Originality/value
LFD is an innovative technique for load prediction and alleviation studies. This paper provides a reference for engineers wishing to use the method for the two mentioned control surfaces, or the like.
Towards a comprehensive conceptual framework for multicultural virtual teams: a multilevel perspective exploring the relationship between multiculturalism and performance
Authors: Chang Rachel Xenia , Carvalho Marly Monteiro , Sbragia Roberto 
Published: December 2022

PurposePerformance in virtual teams, which faces cultural and demographic differences, is a relevant phenomenon that has been widely investigated in recent decades, but with opportunities in exploring other levels of analysis as individual and project. This current research aims to understand how multicultural virtual teams affect individual, team and project performance.Design/methodology/approachThe authors conducted a systematic literature review (SLR) and bibliometric analysis to capture 273 papers from the Web of Science (WoS) database using a snowball approach. In a second approach, the authors selected 130 papers to conduct a content analysis.FindingsThe authors presented a longitudinal overview regarding the adoption of virtual teams in project management (PM) literature. A conceptual framework was proposed to explore the relationship between multicultural virtual teams and performance with three levels of analysis: individual, teams and project. The authors contributed with research hypotheses to be explored in future empirical studies not only at the team perspective but also at the project and individual levels. The thematic analysis suggested that the literature focus has shifted from hard to soft aspects faced by virtual teams. Social identity/categorization theory was the most prominent theory in this body, but it is not fully explored in PM literature. Other opportunities of future studies are to understand the impact of cultural diversity, the sense of belongingness, the project life cycle and the development of a knowledge management program.Originality/valueThe authors developed a 3-level conceptual framework for future empirical studies and demonstrated that cultural differences are mainly approached at the national level in the literature, bringing suggestions for future empirical research.
Country-of-origin and online retailing ethics: the mediating role of trust and satisfaction on purchase intention
Authors: Bhattacharya Saptarshi , Sharma Rajendra Prasad , Gupta Ashish 
Published: December 2022

PurposeOnline shoppers feel insecure due to the various unethical practices of e-tailers. It is, therefore, crucial for online retailers to alleviate customer concerns. Extant literature indicates that country-of-origin (COO) cues influence consumer perception. A relatively underexplored phenomenon in an emerging market context, the COO image of the online retailer, i.e. a foreign-origin online retailer (FOOR) or an Indian-origin online retailer (IOOR), needs validation. The current study investigates customer expectations of online retailers' ethical behaviour against the backdrop of online retailer-based signals in emerging markets.Design/methodology/approachThe researchers floated an online questionnaire using a seven-point Likert scale. The authors sought recipient responses in Google Forms shared via e-mails and social media connections. The authors analysed 1,018 useable responses using partial least square structural equation modelling (PLS-SEM) in Smart PLS 3.FindingsThe empirical study examined the influence of the consumer perception of ethics of online retailers (CPEOR) and COO on consumer purchase intention. It validated the proposed research model. The research findings inform that the CPEOR and the COO influence purchase intention through the mediation effects of trust and satisfaction. Results indicate that privacy, security, non-deception, fulfilment, customer service, FOOR and IOOR strongly predict consumer trust. In contrast, privacy, non-deception, fulfilment, customer service and FOOR strongly predict consumer satisfaction. However, security and IOOR did not influence consumer satisfaction.Research limitations/implicationsThe study results have theoretical and practical implications for academic researchers and online retailing managers. Future studies can validate the model in different geo-demographic scenarios and e-commerce settings.Originality/valueThe study enriches the extant literature on CPEOR in the Indian context. This study is pioneering work examining consumer purchase intention by adding the COO construct to the CPEOR model.
The causal effect of informal job search on wage and job satisfaction: evidence from Egypt and Jordan using random forest method
Authors: Elamin Obbey Ahmed 
Published: December 2022

PurposeThis study aims to examine the impact of finding a job through family and friend contacts on employees' wages and job satisfaction.Design/methodology/approachThis study uses machine learning techniques in economics to estimate the causal effect of being hired through informal contacts on wages and job satisfaction using cross-sectional data from the Higher Education Graduates Survey 2012 (HEGS, 2012) in Egypt and Jordan.FindingsThe author's results confirm that negative and positive consequences are likely to occur. In Egypt, a wage penalty of 28% is estimated in the starting wage, but the impact diminishes in the last wage. By contrast, in Jordan, no penalty is captured in the starting wage, but a premium of 10% is estimated in the last wage. Job satisfaction is negatively affected by the penalty in the starting wage.Social implicationsJob market search methods that allow for professional job referrals, facilitate more efficient information transfer between job-seekers and employers and provide opportunities for job-seekers with weak social capital should be implemented to lower dependence on informal search methods.Originality/valueThe research provides comprehensive evidence about finding a job through informal contact with employees' well-being. The consequences of finding a job using family and friends' contacts, whether positive or negative, cannot be ignored. Future research could benefit from the findings of this study.Peer reviewThe peer review history for this article is available at: https://publons.com/publon/10.1108/IJSE-05-2022-0318.
At the moment of disposal: how messaging techniques at university public outdoor waste receptacles can improve the solid waste stream
Authors: Brinton Amanda , Warner Laura A. , Townsend Timothy G. 
Published: December 2022

Purpose
This study aims to test how waste disposal behaviors can be changed such as higher recycling diversion and lower contamination rates using signage and messaging techniques at public outdoor waste receptacles on a university campus.

Design/methodology/approach
The experiment took place at five public outdoor receptacle stations, each with a landfill and recycling receptacle, which were located in highly trafficked areas on the University of Florida campus. The study consisted of three phases, each lasting for three weeks. During phase one, no signage and messaging were introduced; during phase two, negative and concrete messaging was placed on signs that stood above the two receptacles; and during phase three, positive and abstract messaging was placed above the receptacles. Waste audits were conducted by separating and weighing the waste.

Findings
With signage and messaging implementation, the recycling diversion rates increased and contamination in the recycling receptacles decreased. However, there was not a consistent decrease in contamination in the landfill receptacles. The study also showed that the negative and concrete messaging was more effective at both increasing diversion rates and decreasing contamination rates at the recycling receptacles.

Practical implications
Waste managers on university campuses need to address the purpose and type of messaging being used at waste receptacles to maximize behavior and/or education outcomes.

Originality/value
To the best of the authors’ knowledge, this study represents the first time waste disposal behaviors have been analyzed and experimented on at public outdoor receptacles on a university campus.

Authors: Lang Le Dang , Behl Abhishek , Guzmán Francisco , Pereira Vijay , Del Giudice Manlio 
Published: December 2022

PurposeScholars have paid considerable attention to the importance of brand loyalty of durable consumer products in developed markets. However, no study has investigated the simultaneous impact of advertising efforts, distribution intensity and store image on global brand loyalty (GBL) of fast-moving consumer goods (FMCG) in emerging markets. This study aims to fill this gap.Design/methodology/approachThis study adopts (1) established theoretical lenses: brand equity, marketing mix and cue utilization theories, (2) a mixed-methods approach: a focus group and two surveys and (3) structural equation modeling on two samples of consumers (one homogeneous and one heterogeneous) of global soft drink brands in Vietnam.FindingsThe study reveals significant and nonsignificant relationships among the selected marketing mix elements and brand loyalty and its antecedents of global FMCG. Slight differences in these relationships among the two samples are found. The existing scales are also reconciled with more suitable indicators. The results significantly contribute to the existing knowledge on marketing mix, brand equity and GBL, and global consumer culture.Originality/valueThis is the first study to investigate the simultaneous effects of advertising efforts, distribution intensity, and store image on brand loyalty and its antecedents of global FMCG in an emerging market. The findings will help practitioners develop suitable global branding strategies to manage global brand image and achieve consumer loyalty across emerging markets.
Determinants of loyalty programmes and their impact on store patronage
Authors: Kolte Ashutosh , Veer Nitin , Mahajan Yogesh , Siggia Dario 
Published: December 2022

Purpose
The purpose of this study is to measure the impact of perceived benefits offered by loyalty programmes on store patronage behaviour and repeat purchase behaviour of customers. Another purpose of this study is to assess the impact of mediating and influencing factors on patronage behaviour and customer loyalty.

Design/methodology/approach
The convenience sampling method was adopted for the sample selection. Structured questionnaire instruments were distributed to subscribers who are enrolled or subscribed to any loyalty programme and asked them to mark their opinions about subscriptions to a loyalty programme and the benefits or perceived values that customers get from the subscribed loyalty program. To determine respondent responses, closed-end questions and Likert scales were used. A SmartPLS statistical programme was used to analyse the coefficient and p-value of the perceived value of the loyalty programme and its relation with patronage behaviour.

Findings
The study finds a significant impact of various loyalty programme determinants on store patronage behaviour, supported by hypothesis testing. Researchers have used variable commitment to the test with satisfaction and trust and found it supportive. Another hypothesis tested for the impact of satisfaction on trust shows a significant relationship. They found a significant relationship between the perceived benefits of a loyalty programme and satisfaction with the store and trust. Another hypothesis tested for the impact of satisfaction on trust shows a similar relationship. The impact of commitment on loyalty behaviour (store patronage) was analysed and found to be significant.

Originality/value
To the best of the authors’ knowledge, to date, this methodology has not been used to measure the influence of loyalty programme values on patronage behaviour in the present context. Based on the understanding that the measurement of the impact of perceived values of loyalty programmes on repeat purchase behaviour could be very useful in providing guidance for decision-making in consumer retention strategy, this paper contributes to the literature on the evaluation of store patronage behaviour with its influencing variables.
Influence of formal and informal controls on trust and individual creativity
Authors: Monteiro Januário José , Lunkes Rogério João , Rosa Fabricia 
Published: December 2022

Purpose
This study aims to analyze the influence of formal and informal controls on trust and individual creativity.

Design/methodology/approach
A survey was conducted with managers of companies listed in Brazil Stock Exchange (Brazil, Bolsa, Balcão-B3), and the final sample was 124 valid responses. The data were analyzed using structural equation modeling and fuzzy set qualitative comparative analysis (FsQCA).

Findings
The results show that the influence of informal controls (cultural and personnel controls) on individual creativity is greater than that of formal controls (action and results controls). It was also found that formal and informal controls facilitate social exchanges between managers by influencing trust. Moreover, the results confirmed the mediation of trust in the relationship between controls and individual creativity. FsQCA demonstrates that formal and informal controls are complemented and, when combined with trust, enable high individual creativity.

Originality/value
The findings contribute to the literature by demonstrating that the effective use of management controls generates greater trust and awakens creative skills in managers.
What can satisfy customers in servitization? Service or goods innovation
Authors: Xiao Xiaohong , Zhou Chengxu , Mao Hongyi 
Published: December 2022

Purpose
This study aims to investigate the impact of the two essential subjects of servitization (service and goods innovation) on customer satisfaction. The authors explained the paradox of servitization by determining how service innovation and goods innovation affect customer satisfaction interacting with environmental turbulence and marketing intensity.

Design/methodology/approach
The authors obtained 376 observations of 84 listed Chinese companies. On the basis of content analysis and measurement from secondhand data, the authors first tested the hypotheses in the fixed-effects model. The authors conducted a split-sample analysis by dividing environmental turbulence into two samples to explain the results effectively and better interpret the relationship between two innovations to customer satisfaction.

Findings
The results show that goods and service innovations positively affect customer satisfaction, but the effect of service innovation is more substantial. Furthermore, environmental turbulence negatively moderates the relationship between service innovation and customer satisfaction. The empirical results indicated that, if enterprises enhance marketing intensity, then the growth of environmental turbulence weakens the positive impact of goods and services innovation on customer satisfaction.

Originality/value
This study provided an understanding of the impact of servitization on intangible assets. This study also responded to previous literature’s call for research on the impact of external environmental factors on servitization.
