Determining the effect of air transportation on air pollution in the most polluted city in Turkey
Authors: Gürçam Selçuk , Konuralp Emrah , Ekici Selcuk 
Published: March 2021

Purpose
This study was carried out in Igdir, where Turkey’s urban air pollution is at the highest level, and the population is among the smallest. Thus, the study aims to determine the effect of air transportation on air pollution in the most polluted city in Turkey.

Design/methodology/approach
The approach includes six stages: choosing the airport, accessing the flight information for the airport, classifying the aircraft that operated at the airport, determining the aircraft engines, calculating the emission amounts, calculating the landing and takeoff-based emissions.

Findings
Rather than devoting the resources disproportionally to the aviation sector within the scope of economic globalization, as a policy recommendation, to realize its production potential, Igdir, which has a great agricultural production capacity, considering its microclimate, fertile soil and arable land, should be urgently integrated into neighboring markets and the national market via railways.

Practical implications
It is inferred from the research that Turkey has to consider implementing the emissions tax policy, while the Turkish aviation sector is to realize new regulations for aircraft-engine matching to take public health and the impacts of the airports on their surroundings into consideration more seriously.

Originality/value
This study is an original one, as it puts the increasing pollution caused by the aircraft into a historical and political-economic perspective. Also, it is an example of an interdisciplinary work that combines environmental science and political science.
The use of FEA and semi-empirical equations for weight estimation of a passenger aircraft
Authors: Kowalski Mariusz , Goraj Zdobyslaw Jan , Goliszek Bartłomiej 
Published: March 2021

Purpose
The purpose of this paper is to present the result of calculations that were performed to estimate the structural weight of the passenger aircraft using novel technological solution. Mass penalty resulting from the installation of the fuselage boundary layer ingestion device was needed in the CENTRELINE project to be able to estimate the real benefits of the applied technology.

Design/methodology/approach
This paper focusses on the finite element analysis (FEA) of the fuselage and wing primary load-carrying structures. Masses obtained in these analyses were used as an input for the total structural mass calculation based on semi-empirical equations.

Findings
Combining FEA with semi-empirical equations makes it possible to estimate the mass of structures at an early technology readiness level and gives the possibility of obtaining more accurate results than those obtained using only empirical formulas. The applied methodology allows estimating the mass in case of using unusual structural solutions, which are not covered by formulas available in the literature.

Practical implications
Accurate structural mass estimation is possible at an earlier design stage of the project based on the presented methodology, which allows for easier and less costly changes in designed aircrafts.

Originality/value
The presented methodology is an original method of mass estimation based on a two-track approach. The analytical formulas available in the literature have worked well for aeroplanes of conventional design, but thanks to the connection with FEA presented in this paper, it is possible to estimate the structure mass of aeroplanes using unconventional technological solutions.

Published: March 2021

PurposeThis study investigates how game design, which divides players into static teams, can reinforce group polarisation. The authors study this phenomenon from the perspective of social identity in the context of team-based location-based games, with a focus on game slang.Design/methodology/approachThe authors performed an exploratory data analysis on an original dataset of n = 242,852 messages from five communication channels to find differences in game slang adoption between three teams in the location-based augmented reality game Pokémon GO. A divisive word “jym” (i.e. a Finnish slang derivative of the word “gym”) was discovered, and players' attitudes towards the word were further probed with a survey (n = 185). Finally, selected participants (n = 25) were interviewed in person to discover any underlying reasons for the observed polarised attitudes.FindingsThe players' teams were correlated with attitudes towards “jym”. Face-to-face interviews revealed association of the word to a particular player subgroup and it being used with improper grammar as reasons for the observed negative attitudes. Conflict over (virtual) territorial resources reinforced the polarisation.Practical implicationsGame design with static teams and inter-team conflict influences players' social and linguistic identity, which subsequently may result in divisive stratification among otherwise cooperative or friendly player-base.Originality/valueThe presented multi-method study connecting linguistic and social stratification is a novel approach to gaining insight on human social interactions, polarisation and group behaviour in the context of location-based games.

Published: March 2021

PurposeSome progress have been made over time in improving health conditions in Sub-Saharan Africa (SSA). There are, however, contradicting reports on the relationship between health outcomes and economic growth in the region. The paper aimed at assessing the effect of health outcome on economic growth in SSA.Design/methodology/approachData for 41 countries from 2000 to 2018 were obtained from WDI and WGI and analyzed using system generalized method of moment (sGMM) which is appropriate for the present scenario. AR(1) and AR(2) tests were used to assess the validity of the model while Sargan and Hansen tests were adopted to examine the validity of the instrumental variables. The robustness of the estimation was confirmed using the pooled OLS and fixed effect regression.FindingsHealth outcome (proxied by life expectancy), lagged GDP per capita, capital formation, labor force (LF), health expenditure (HE), foreign direct investment (FDI) and trade openness (TOP) significantly affected economic growth emphasizing the importance of health in the process of economic growth in the region. AR(1) and AR(2) tests for serial correlation and Sargan/Hansen tests confirmed the validity of the estimated model and the instrumental variables respectively. Robustness of the GMM results was established from the pooled OLS and the fixed effect model results.Social implicationsImprovement in the national health system possibly through the widespread adoption of National Health Insurance, increase government spending on healthcare alongside increased beneficial trade and ease of doing business to facilitate investment were recommended to enhance.Originality/valueThe study used up-to-date data with appropriate methodology.

Authors: Eken Taha Yasin , Sarioglu Cevat , Kucuk Israfil 
Published: March 2021

Purpose
The purpose of this paper is to investigate and find out the surface and electrochemical behaviours of twin roll cast (TRC) 8006 aluminium alloy with different thicknesses due to the cold rolling rates after the TRC process.

Design/methodology/approach
The 8006 aluminium alloys are mostly used for the food packaging industry, as they are corrosion resistant, lightweight and shapable materials. The present work investigates the surface and corrosion behaviours of 8006 aluminium alloys at different thicknesses. TRC aluminium alloys were cold-rolled at two different reduction rates before investigation. X-ray diffraction (XRD) and energy dispersive spectroscopy (EDX) tests were used to examine the phase and elemental analyses. FE-SEM and 3D profilometry also used to observe surface morphology. Open circuit potential (OCP), potentiodynamic polarization and electrochemical impedance spectroscopy tests (EIS) were carried out to find out corrosion behaviours. The results show that the more cold rolling reduction (CRR), the more corrosion rate and surface affection of the TRC 8006 aluminium alloys.

Findings
According to the electrochemical tests (OCP, potentiodynamic polarization test and EIS) and surface morphology results (such as SEM, 3D profilometry and XRD) the more the rolling rate the less the corrosion resistance.

Originality/value
First corrosion behaviour investigation of twin-rolled 8006 Al alloys using electrochemical techniques. First investigation of CRR effects on electrochemical corrosion behaviour of 8006 Al alloys with 3.5 wt.% NaCl solution using EIS. First investigation of 8006 Al alloys as a food packaging material with electrochemical ways.

Published: March 2021

PurposeThis qualitative approach study aimed to understand the barriers to accessing a tuberculosis (TB) clinic in a Thai hospital as experienced by TB patients from Myanmar living on the Thailand-Myanmar border.Design/methodology/approachTwenty-two participants were asked to provide information. In-depth interviews were used to gather the information. Each interview lasted 40 min.FindingsTB patients from Myanmar experience several barriers to accessing TB treatment and care at Mae Sai Hospital, such as language and economic problems, although they are very satisfied with the quality of service and positive attitude of the health care providers. A long waiting time and lack of explanation of the pathogenesis of TB were noted as negative aspects by the patients and their relatives. The medical staff at the TB clinic were negatively affected by the excessive workload and unsuitability of some methods or technologies. Using budgetary subsidies from agencies to fund TB care and treatment was not sustainable. Foreign TB patients are not subsidized by the national universal insurance scheme of Thailand, and sending TB patients back to their home country is sometimes unavoidable.Originality/valueThailand and Myanmar should strengthen their collaboration and develop a system to improve the quality of TB patient care and management for those who are living in poverty and lack education, by focusing on reducing language and economic barriers to accessing health care services including support for medicines and laboratory materials related to TB case management among these populations.

Published: March 2021

PurposeThis study integrates the providers' perspective as well as the patient's perspective in developing and validating a scale to measure hospital service quality in multispecialty hospitals.Design/methodology/approachAn exploratory sequential mixed-method approach was used in this study. The strategies used included a thematic literature review, semi-structured interviews, modified Delphi and confirmatory factor analysis.FindingsThe reliability coefficient of 41 item scale was 0.963 with each attribute, that is, pivotal, core and peripheral, having a Cronbach's alpha of 0.907, 0.91 and 0.891, with scale content validity (S-CVI Ave) of 0.9151. The composite reliability scores of all constructs were greater than 0.7, with an Average Variance Explained (AVE) of all items greater than 0.5.Originality/valueThe instrument can be used to measure the difference between what service providers believe customers expect and customers’ actual needs and expectations. The scale can be used to measure the difference between what is delivered (as perceived by the provider) and what customers perceive they have received (because they are unable to accurately evaluate service quality). The dyadic approach of administering this questionnaire in measuring hospital service quality will lead to the identification of a knowledge gap and a perception gap in delivering hospital service quality.

Published: March 2021

PurposeIn this paper, the impact of customer incivility on work engagement was investigated. The authors also explored whether supervisor positive gossip and workplace friendship prevalence moderated the impact of customer incivility on work engagement in the Nigerian context.Design/methodology/approachThe authors used a time-lagged design to collect data from 258 frontline casual dining restaurant employees across city centers in South-eastern Nigeria who completed Time 1 and Time 2 paper surveys after a one-month interval.FindingsStructural equation modeling (SEM) revealed that while customer incivility was negatively lx`inked to work engagement, supervisor positive gossip and workplace friendship prevalence were positively linked to work engagement. It was also found that both supervisor positive gossip and workplace friendship prevalence moderated the negative connection between customer incivility and work engagement.Practical implicationsOne proactive way to forestall the negative impact of customer incivility on work engagement is for managers to devise approaches to decrease the impact of uncivil customer behaviors, such as developing an atmosphere that engenders friendship and speaking positively to subordinates about other employees' work behaviors.Originality/valueAlthough increased scholarly attention has been paid to workplace incivility, customer incivility has not been sufficiently addressed. Earlier research on workplace gossip is influenced by the widely-held belief that gossip is often negative, with far less attention given to the sunny side of gossip. This study is one of the earliest efforts to examine the moderating roles of supervisor positive gossip and workplace friendship prevalence in the negative link between customer incivility and work engagement in the hospitality industry.

Published: March 2021

PurposeIn many healthcare systems, health policy has committed to delivering an integrated model of care to address the increasing burden of disease. The interface between primary and secondary care has been identified as a problem area. This paper aims to undertake a scoping review to gain a deeper understanding of the markers of integration across the primary–secondary interface.Design/methodology/approachA search was conducted of PubMed, SCOPUS, Cochrane Library and the grey literature for papers published in English using the framework described by Arksey and O'Malley. The search process was guided by the “Preferred Reporting Items for Systematic Reviews and Meta-Analyses” (PRISMA).FindingsThe initial database search identified 112 articles, which were screened by title and abstract. A total of 26 articles were selected for full-text review, after which nine articles were excluded as they were not relevant to the research question or the full text was not available. In total, 17 studies were included in the review. A range of study designs were identified including a systematic review (n = 3), mixed methods study (n = 5), qualitative (n = 6) and quantitative (n = 3). The included studies documented integration across the primary–secondary interface; integration measurement and factors affecting care coordination.Originality/valueMany studies examine individual aspects of integration. However, this study is unique as it provides a comprehensive overview of the many perspectives and methodological approaches involved with evaluating integration within the primary–secondary care interface and primary care itself. Further research is required to establish valid reliable tools for measurement and implementation.

Published: March 2021

PurposeThe purpose of this paper is to identify the development of the digital transformation literature and to the systematic literature review methodology.Design/methodology/approachThe authors run a systematic literature review, followed by a rigorous thematic analysis of both academic and grey literature dataset, in order to develop a conceptual map of organizations' digital transformation. The authors aggregate the concepts and topics identified across the literature to find that they overwhelmingly tackle digital business models. At the same time, the authors identify a major blind spot resulting from ignoring the organization itself as a unit of analysis.FindingsThe findings show that developing a digital theory of the organization or the theory of digitally transformed organization is a major challenge to management researchers. The analysis exposed numerous research gaps that can be helpful for future research directions.Originality/valueDigital transformation research enjoys an increasingly rapid rise to recognition across many academic disciplines and strongly impacts the management domain. adopt the view that published documents reflect the collective understanding of a phenomenon. This paper contributes to filtering the digital transformation literature, clarify complex relation between digital transformations of organizations and identify the key blind points.

Published: March 2021

PurposeThe SARS-CoV-2 pandemic has caused a major impact on worldwide public health and economics. The lessons learned from the successful attempts to contain the pandemic escalation revealed that the wise usage of contact tracing and information systems can widely help the containment work of any contagious disease. In this context, this paper investigates other researches on this domain, as well as the main issues related to the practical implementation of such systems and specifies a technical solution.Design/methodology/approachThe proposed solution is based on the automatic identification of relevant contacts between infected or suspected people with susceptible people; inference of contamination risk based on symptoms history, user navigation records and contact information; real-time georeferenced information of population density of infected or suspect people; and automatic individual social distancing recommendation calculated through the individual contamination risk and the worsening of clinical condition risk.FindingsThe solution was specified, prototyped and evaluated by potential users and health authorities. The proposed solution has the potential of becoming a reference on how to coordinate the efforts of health authorities and the population on epidemic control.Originality/valueThis paper proposed an original information system for epidemic control which was applied for the SARS-CoV-2 pandemic and could be easily extended to other epidemics.
Microseismic waveform and shear‐wave splitting analysis with model data
Authors: White Isabel , Bray Matthew , Simmons James 
Published: March 2021

ABSTRACTAccurate and precise estimation of microseismic event location in anisotropic reservoirs is challenging with borehole acquisition, due to limited azimuthal and inclination coverage. Inclusion of shear‐wave splitting information from microseismic data can improve estimates of event directivity, source location and the degree of reservoir anisotropy compared with using P‐waves alone. Additionally, S‐waves typically have a higher signal‐to‐noise ratio than P‐waves, due to higher amplitudes, decreasing the overall azimuthal and depth uncertainty in comparison with P‐wave only location methodologies. We present a joint P‐ and S‐wave hodogram workflow to reduce azimuthal uncertainty and estimate shear‐wave splitting. In this paper, finite‐difference waveform synthetics verify the workflow and illustrate interference effects associated with reflections and head‐waves. Multiple shear‐wave splitting techniques are applied to the synthetic data set in order to understand the limitations between splitting methodologies. Combining the P‐wave hodogram calculation of azimuth and inclination with the shear‐wave splitting analysis lowers the azimuthal uncertainty and improves waveform rotation results. From the comparison of three splitting methods, the minimum second eigenvalue is the most optimum for the data set. Post‐splitting analysis was key as the results are affected by the complexities in the waveforms and arrivals. Using receiver‐by‐receiver splitting quality analysis with shot and receiver clustering improves the identification of quality splitting results.
