The UAM service network: multi-objective and multi-period design for UAM airports
Authors: Boo Jeongjoon , Lee Seung Yeob , Song Byung Duk 
Published: June 2023

PurposeThe next generation of mobility is arising, and various challenging mobilities have entered the limelight. One of the most exciting of these is urban air mobility (UAM), and one of its challenges is constructing effective and efficient UAM service network. This study took a quantitative approach to the problem in an effort to support and facilitate the UAM service industry.Design/methodology/approachThis study derived a multi-objective and multi-period (MOMP) location optimization model to support strategic UAM service network design. The model, based on its long-term service plan, determines where and when to open UAM airports. In addition, this study applied a modified e-constraint algorithm to derive managerial decisions on the Pareto relationship in consideration of multiple objectives and multiple periods.FindingsEach Pareto solution represents a different UAM service network configuration. Thus, the model can analyze the trade-offs between Pareto decisions for the UAM service network. A case study of UAM service network design in South Korea demonstrates the validity of the proposed mathematical model and algorithm.Practical implicationsThe design of a UAM service network should consider various aspects. Its construction and operation would require significant investments of time, capital and people, which would redound to society over a significant span of time. The results of this study provide quantitative guidelines for derivation and analysis of various UAM service network configurations in consideration of multiple objectives and multiple periods.Originality/valueThis paper proposes MOMP optimization, which approach is suitable to the fundamental characteristics of expanding UAM service networks and their design. It is expected that the present study will make significant contributions to the efforts of those deriving and analyzing future UAM service networks.
Effect of green advertising attitude on collectivist consumer behavior: an integrative approach
Authors: Lee Joseph Lok-Man , Liu Vanessa , Cheng Calvin 
Published: June 2023

PurposeUnlike traditional products and services, customer motivation to purchase green products/services may be due to non-marketing factors, such as their personal values about health. In this study, the authors aim to propose and validate an integrative model using both advertising attitude factors and health beliefs to explain purchase intention and word of mouth in the context of green marketing. The authors focus specifically on collectivist consumers as values and social norms that tend to be more salient in driving their decisions.Design/methodology/approachThe model was tested empirically using a survey study with 308 Chinese consumers in Hong Kong. The data were analyzed using confirmatory composite analysis (CCA) and partial least squares structural equation modeling.FindingsAll health beliefs were significant predictors of green advertising attitude. Green satisfaction fully mediates the relationship between green advertising attitude and positive word of mouth for products and services with green advertising for collectivist Chinese consumers. Meanwhile, green satisfaction partially mediates the relationship between green advertising attitude and purchase intention. In addition, green brand equity partially mediates the green advertising attitude–purchase intention/positive word of mouth link.Practical implicationsThe significant impacts of health belief factors on green advertising attitude present important implications to advertising managers in terms of the use of information appeal in promoting green products/services. Green brand equity should also be developed in order to optimize green advertising effectiveness, especially in the context of collectivist customers.Originality/valueThis research is one of the first few studies investigating the mediating role of green satisfaction and green brand equity for collectivist consumer behaviors based on the health belief model (HBM).
Natural convection of a reacting hybrid nanofluid in an open porous cavity bounded by vertical wavy walls
Authors: Roy Nepal Chandra , Monira Sherajum 
Published: June 2023

Purpose
The purpose of this study is to investigate the natural convection characteristics of a reacting hybrid nanofluid in an open porous cavity bounded by vertical wavy walls subject to an inclined magnetic field.

Design/methodology/approach
The physical domain of the problem is constructed using coordinate transformations, and the equations are transformed accordingly. The resulting equations are then solved using finite difference method. Numerical results for the streamlines, isotherms and isoconcentration are illustrated with varying relevant parameters.

Findings
Whatever the values of parameters, streamlines have two counter-rotating cells, and their intensities are the highest near the open end. Moreover, the maximum temperature and the minimum concentration are obtained in close proximity to the open end. The strength of streamlines is increased with increasing Rayleigh number, Frank-Kamenetskii number and Darcy number, whereas it is decreased with the increment of volume fractions of nanoparticles.

Research limitations/implications
The limitations of this study are that the model is suitable for thermal equilibrium cases and constant thermo-physical properties, while the results can predict two-dimensional flow behaviors.

Originality/value
To the best of the authors’ knowledge, there is no study on the natural convection induced by a chemical reaction in an open cavity bounded by vertical wavy walls. The findings might be used to gather knowledge about the flow, energy and reactant distributions in an open space containing a chemical reaction.
Does AIS usage matter in SMEs performance? an empirical investigation under digital transformation revolution
Authors: Al-Okaily Manaf 
Published: June 2023

PurposeThe purpose of this study is to gain empirical insights into whether accounting information systems (AIS) usage matters among Jordanian small and medium-sized enterprises (SMEs) during the period of COVID-19 pandemic.Design/methodology/approachThe suggested research model in the current study is based on the extending technology acceptance model (TAM) to test the antecedents’ factors that impact on AIS usage among SMEs. To test the proposed research model, partial least squares structural equation modeling (PLS-SEM) was used.FindingsThe empirical findings revealed all postulated hypotheses were accepted exceptH3. Contrary to what is expected, the empirical outcomes confirmed that perceived compatibility does not affect the perceived usefulness of AIS, and hence, the related hypothesis was rejected.Originality/valueThe results of the current research could be beneficial to a number of managers (owners) to obtain a better understanding of the benefits of AIS success usage among Jordanian SMEs performance during crises time as the COVID-19 pandemic crisis.
Leadership style as an antecedent to effective Six Sigma implementation
Authors: Bagherian Anthony , Gershon Mark , Kumar Sunil 
Published: June 2023

PurposeThe effectiveness of Six Sigma programs has varied across different industries and organizations, and leadership styles have been identified as a critical success factor for the installation of Six Sigma initiatives. Therefore, this study aims to investigate the specific elements of leadership styles that are linked with the successful deployment of Six Sigma programs in the automobile industry.Design/methodology/approachTo conduct the study, the researchers utilized a Likert scale questionnaire with a rating system of 1–7 and a simple random sampling method. The survey was distributed to 2,325 potential participants, with 573 responses received, mostly from Germany, the United Kingdom and Sweden. Out of those responses, 260 completed questionnaires were received. The study utilized a mixed-methods research design and exploratory research approaches to investigate the implication of leadership style on the success of Six Sigma implementation. The research employed several analysis techniques, including Structural Equation Modeling (SEM), exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and Survey methods.FindingsThrough various SEM methods, such as EFA and CFA, the study revealed two vital leadership elements: (1) the long-term success of Six Sigma depends on leadership’s support and recognition of it as an improvement strategy and (2) leadership must commit to the organization’s suppliers to ensure quality and the provision of defect-free products.Practical implicationsBy incorporating the identified key elements of leadership into their strategies, organizations and researchers can ensure the sustainable implementation of Six Sigma.Originality/valueThis research presents a distinct contribution to the evaluation of leadership style components within the European automotive sector, utilizing a mixed-methods research design and incorporating a variety of descriptive statistics.
Capital as the outcome of information practices: a study of devotees and monks of a Theravada Buddhist Temple
Authors: Yerbury Hilary , Olsson Michael , Perera Pethigamage 
Published: June 2023

PurposeThe outcomes of information behaviours have traditionally been conceptualised as use or effects. The adoption of a sociological stance, based on a practices approach, provides the opportunity to challenge these understandings. The non-Western setting further enhances the possibilities for conceptualising the outcomes of information practices as forms of capital.Design/methodology/approachThis ethnographic study uses a Bourdieusian approach to investigate the information practices of diasporic devotees and monks of a Theravada Buddhist Temple in Sydney, Australia. The insider position of one researcher brought strong insights into the data, while the theoretical approach shared with the other researchers reinforced an outsider perspective.FindingsThe Temple’s online sources and personal communication with other devotees provide a diverse range of sources that devotees use in information-based cultural practices and everyday life information practices. These practices lead to outcomes that can be identified as economic, social and cultural capital. Pin or merit emerges as an important outcome of practices which is not easily accommodated by the concept of outcome, nor by Bourdieu’s categories of capital.Originality/valueAdding to the small number of studies concerned with information practices in a spiritual context, this study shows the value of a Bourdieusian approach in identifying the outcomes of information practices as capital, but highlights the shortcomings of applying Western concepts in non-Western settings. It proposes the possibility of a new form of capital, which will need to be tested rigorously in studies in other spiritual settings.
Condominiums facing delinquency: stringent remedies from a comparative perspective
Authors: Simón-Moreno Héctor 
Published: June 2023

Purpose
With the aim of monitoring the existing regulations that are applicable to community of owners facing delinquency, in view of the importance of this issue for the achievement of the Urban Agenda, the present study aims to analyse the most stringent and controversial measures available for the community of owners facing delinquency from a comparative perspective.

Design/methodology/approach
The present work addresses the recent legislative amendments that have taken place at national level in this field in several countries and analyses to what extent they have addressed the delinquency problem faced by community of owners.

Findings
The current paper shows that, in the end, legal certainty, the prospective legal and economic effects on mortgage lending and constitutional concerns are the underlying reasons behind the reluctance to implement some stringent measures to face delinquency. It also shows that recent amendments concerning alternative dispute resolution mechanisms are a missed opportunity.

Social implications
Community of owners plays a key role in cities for the achievement of the Urban Agenda, so the periodical contributions from co-owners are paramount to the proper implementation of urban regeneration, energy efficiency and accessibility policies. To this end, the paper analyses existing regulations that are applicable to community of owners facing delinquency, which may increase in the coming years due to the current socioeconomic context.

Originality/value
This paper builds on existing research and goes one step further by addressing the recent legislative amendments that have taken place recently at national level in this field. These measures may serve as an inspiration to other EU legal systems.
Do fiscal rules of local debt affect municipal off-budget activities? Analysis of various types of municipalities
Authors: Białek-Jaworska Anna , Kopańska Agnieszka Krystyna 
Published: June 2023

PurposeThis paper aims to determine whether local governments (LGs) use non-consolidated municipally owned companies (MOCs), excluded from public sector entities and, consequently, from sub-national debt to avoid fiscal debt limits. This paper contributes to the literature by analysing the fiscal debt rule’s impact on the off-budget municipal activities in total and separate in different types of local government units.Design/methodology/approachThis paper uses difference-in-differences and the system general method of moments model with the Blundell–Bond estimator for dynamic panel data analysis of MOCs owned by 866 Polish municipalities in 2010–2018.FindingsThis paper shows that the MOCs’ revenues support limited local public debt capacity by indebtedness restrictions imposed on municipalities in 2014. As a result, less indebted municipalities have higher off-budget revenues. The tightening of fiscal rules related to sub-sovereign indebtedness increased off-budget activities, but that effect is much stronger in rural and rural–urban municipalities than in urban municipalities and big cities.Originality/valueThis paper contributes to the literature by exploring the fiscal debt rule’s impact on the off-budget municipal activities in total and separate in different types of local government units. In this paper, the authors combine theories relating to private and public finance; this is a novel approach and one that is also necessary – as, in fact, the worlds of public and private actors intersect – as exemplified by the existence of MOC.

Published: June 2023

PurposePatronage of local footwear have not been encouraging in Nigeria despite recent investments. The purpose of the study is to evaluate celebrity endorsement and customer patronage of small and medium-scale enterprises (SMEs) products in African context, with focus on trustworthiness, expertise, attractiveness, respect and similarity (TEARS) model.Design/methodology/approachThe research was designed as a descriptive survey. An online structured questionnaire was applied for data collection. Cronbach Alpha and content validity were used for reliability and validity, respectively. TEARS model was used to ascertain key dimensions, and Pearson correlation coefficient and logistic regression were applied into the analysis.FindingsThe findings reveal that celebrity endorsement is not associated with patronage of local footwears, though TEARS model analysis indicates the direction of consumers rating on celebrity endorsement. Factors such as recommendation and quality impact the consumer willingness to buy local footwear.Research limitations/implicationsThe small sample size calls for caution in generalization.Practical implicationsThe study suggests that although the TEARs model is viable, all the dimensions are mutually exclusive. However, this depends on the characteristics of the brand. In driving patronage, managers must pay attention to personal and non-personal cues such as price, quality and source of information about their brand.Originality/valueThe originality is buttressed from the value it provides for local product production and patronage. The significant factors are indicated as key to addressing low patronage.
Achieving supply chain resilience in an era of disruptions: a configuration approach of capacities and strategies
Authors: Gaudenzi Barbara , Pellegrino Roberta , Confente Ilenia 
Published: June 2023

Purpose
The COVID-19 pandemic and recent disruptive events are affecting firms’ operations and supply chain networks on a large scale, causing disturbances in supply, demand, production and logistics activities. Although supply chain resilience (SCR) research has received large attention in recent years, the purpose of this paper is to offer an original contribution by exploring how complex configurations and interactions between SCR strategies and capacities can lead to resilience.

Design/methodology/approach
This study investigates the configurations of SCR strategies and capacities using a fuzzy-set qualitative comparative analysis.

Findings
First, the findings reveal different SCR strategy configurations through the lens of absorptive, reactive and restorative capacities to achieve resilience. Second, this study applies the contingent resource-based view (CRBV) perspective to interpret how organizations can achieve resilience before, during and after a disruptive event. Third, it offers an analysis of different groups of organizations, based on the adoption of different SCR strategies and capacities.

Originality/value
This study identifies a set of equifinal SCR strategies and capacity configurations that can be implemented to cope with a disruptive event and lead to resilience. It also enriches the research addressing the consecutive phases of SCR investments, developing the CRBV perspective. In our results, five solutions describe organizations that invest in absorptive capacities, representing an ex ante readiness.

Authors: Chenger Denise , Pettigrew Rachael N. 
Published: June 2023

PurposeCompanies are turning to big data (BD) programs to help mitigate supply chain (SC) disruptions and risks that are increasing in frequency and severity. The purpose of this paper is to explore exactly how companies translate data into meaningful information used to manage SC risk and create economic value; an area not well researched. As companies are turning to big-data programs to help mitigate supply chain (SC) disruptions and risks that are increasing in frequency and severity, having the capability to internally integrate SC information is cited as the most critical risk to manage.Design/methodology/approachInformation processing theory and resource-based view are applied to support capability development used to make value-based BD decisions. Semi-structured interviews were conducted with leaders in both the oil and gas industry and logistics SC partners to explore each companies’ BD transformation.FindingsFindings illuminate how companies can build internal capability to more effectively manage SC risk, optimize operating assets and drive employee engagement.Research limitations/implicationsThe oil and gas industry were early adopters of gathering BD; more studies addressing how companies translate data to create value and manage SC risk would be beneficial.Practical implicationsGuidance for senior leaders to proactively introduce BD to their company through a practical framework. Further, this study provides insight into where the maximum benefit may reside, as data intersects with other company resources to build an internal capability.Originality/valueThis study presents a framework highlighting best practices for introducing BD plus creating a culture capable of using that data to reduce risk during design, implementation and ongoing operations. The steps for producing the maximum benefit are laid out in this study.
A workflow for processing mono‐channel Chirp and Boomer surveys
Authors: Vesnaver Aldo , Baradello Luca 
Published: June 2023

AbstractAcquiring seismic data with multichannel, multiple‐streamer and even multi‐componentsystems at sea provides excellent images of the Earth. However, the cost and complexity of operations prevent their use in busy areas such as ports or in sensitive environments such as lagoons. In the latter cases, mono‐channel Chirp or Boomer systems are the most viable instruments for marine surveys. The lack of multiple offsets prevents the use of standard tools for amplitude‐versus‐offset and velocity analysis, which are necessary for the lithological characterization of rocks, especially for the shallow sediments in offshore engineering. In this paper, we present a few recent techniques that exploit the traveltime and amplitude of multiple reflections to compensate for the offset limitation, including a new algorithm for the joint tomographic inversion of direct arrivals, primaries and multiples. We have developed a cost‐effective workflow for mono‐channel surveys based on a data‐driven, physically consistent philosophy that attempts to approximately extract lithological parameters, such as P velocity, anelastic absorption, acoustic impedance and even density. We applied the proposed workflow to a real field experiment and obtained a semi‐quantitative estimate for shallow sediments that can be used by offshore engineers.

Published: June 2023

AbstractBackgroundGasless laparoscopy (GL) emerged to overcome the clinical and financial challenges of pneumoperitoneum and is often seen as a viable option for use in resource‐limited settings as a means of saving costs and resources. This study aims to systematically review the evidence available on the safety and efficiency of GL compared with conventional laparoscopy (CL) and laparotomy.MethodsFollowing the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines, Medline, Embase, Web of Science and Cochrane databases were searched. Variables of interest were determined a priori and Covidence software was used to screen studies for inclusion without demographic preference. The quality of studies was assessed using the Cochrane Risk Assessment tool.ResultsOf the 1080 studies screened, a total of 43 studies were included. Laparoscopic cholecystectomy was by far the most studied intervention in randomised studies. In these, the mean setup time for gasless and CL was 13.14 (95% CI −0.16 to 26.44) and 12.8 (95% CI −10.86 to 36.47) minutes, respectively. The mean duration of surgery for gasless and CL was 89.39 (95% CI 77.44 to 101.34) and 72.59 (95% CI 63.44 to 81.74) minutes, respectively, and the mean length of stay was 4.25 (95% CI 2.02 to 6.48) and 4.04 (95% CI 1.72 to 6.36) days, respectively. Most reported complications were haemorrhage and infection with no assessable statistical difference.ConclusionsAlthough GL seems to be a feasible approach for many general surgery interventions, the observed outcomes based on safety and efficiency are not sufficient to recommend GL as an alternative to CL or laparotomy. Larger randomised trials with a low risk of bias are warranted.
