Chasing the fitness optimum: temporal variation in the genetic and environmental expression of life-history traits for a perennial plant
Authors: Kulbaba Mason W. , Yoko Zebadiah , Hamilton Jill A. 
Published: October 2021

AbstractThe ability of plants to track shifting fitness optima is crucial within the context of global change, where increasing environmental extremes may have dramatic consequences to life history, fitness, and ultimately species persistence. However, to track changing conditions relies upon the complex relationship between genetic and environmental variance, where selection may favor plasticity, the evolution of genetic differences, or both depending on the spatial and temporal scale of environmental heterogeneity. Over three years, we compared the genetic and environmental components of phenological and life-history variation in a common environment for the spring perennialGeum triflorum. Populations were sourced from alvar habitats that exhibit extreme, but predictable annual flood-desiccation cycles and prairie habitats that exhibit similar, but less predictable variation in water availability. Narrow-sense heritabilities were generally higher for early life history (emergence probability) relative to later life history traits (total seed mass), indicating that traits associated with establishment within an environment are under stronger genetic control relative to later life-history fitness expressions, where plasticity may play a larger role. This pattern was particularly notable in seeds sourced from environmentally extreme, but predictable alvar habitats relative to less predictable prairie seed sources. Fitness landscapes based on seed source origin, largely characterized by varying water availability and flower production, described selection as the degree of maladaptation to the prairie common garden environment relative to seed source environment. Plants from alvar populations were consistently closer to the fitness optimum across all years. Annually, the breadth of the fitness optimum expanded primarily along a moisture gradient, with inclusion of more populations onto the expanding optimum. These results highlight the importance of temporally and spatially varying selection for the evolution of life history, indicating plasticity within perennial systems may over time become the primary mechanism to track fitness for later life history events.
Using social media for flight path safety assessment
Authors: Abin Ahmad Ali , Nabavi Shahabedin , Ebrahimi Moghaddam Mohsen 
Published: October 2021

Purpose
Artificial intelligence (AI)-based systems can save the lives of many people by assessing the safety of flight paths. Unfortunately, the world witnessed a horrible event in January 2020 with the case of flight 752 of Ukrainian International Airlines from Tehran to Kiev and it has prompted us to ask how AI can prevent such events by warning to flight path planners. This paper aims to propose a framework for assessing the safety of flight paths from a shooting of an airplane by air defense systems installed on the path. Unlike the existing studies, this study takes a new look at pre-flight risk assessment by using textual information in social and news networks. To this end, the authors use existing information retrieval techniques to identify high flight risk areas by examining the news articles, comments, posts, tweets, etc., in social media and then estimate the probability of targeting a passenger aircraft by the air defense systems probably installed on high-risk areas with the help of a statistical model. This estimation can then be used by fight planners to avoid such events.

Design/methodology/approach
To design a framework for estimating the probability of a fatal shooting of an airplane by air defense systems installed on its flight path, the authors have used the idea of information retrieval in conjunction with statistical methods. The authors have extracted some significant variables in the shooting of flights and proposed an AI-based framework to estimate the probability of a fatal shooting of an airplane during its flight and sketched a case study for using machine learning approaches to assist with flight path planning. As a case study, the authors covered flight 752 to explain the usefulness of the proposed framework in this context.

Findings
Unlike the existing methods, this study investigates flight path safety assessment from the social media and crowdsourcing perspective. In this study, the authors proposed an AI-based framework to avoid aviation hazards by estimating the probability of a shooting of an airplane by air defense systems installed on its flight path. Moreover, this study was designed to show how estimating the safety of flight paths by using AI-based methods can help flight planners to avoid such events and gain further insights into the use of AI-based systems in pre-flight risk assessment.

Originality/value
The idea behind the proposed method is original and as the authors’ best knowledge, there is no similar framework using social media for flight path safety assessment.
The effect of credit risk management and bank-specific factors on the financial performance of the South Asian commercial banks
Authors: Siddique Asima , Khan Muhammad Asif , Khan Zeeshan 
Published: October 2021

PurposeAmong all of the world's continents, Asia is the most important continent and contributes 60% of world growth but facing the serving issue of high nonperforming loans (NPLs). Therefore, the current study aims to capture the effect of credit risk management and bank-specific factors on South Asian commercial banks' financial performance (FP). The credit risk measures used in this study were NPLs and capital adequacy ratio (CAR), while cost-efficiency ratio (CER), average lending rate (ALR) and liquidity ratio (LR) were used as bank-specific factors. On the other hand, return on equity (ROE) and return on the asset (ROA) were taken as a measure of FP.Design/methodology/approachSecondary data were collected from 19 commercial banks (10 commercial banks from Pakistan and 9 commercial banks from India) in the country for a period of 10 years from 2009 to 2018. The generalized method of moment (GMM) is used for the coefficient estimation to overcome the effects of some endogenous variables.FindingsThe results indicated that NPLs, CER and LR have significantly negatively related to FP (ROA and ROE), while CAR and ALR have significantly positively related to the FP of the Asian commercial banks.Practical implicationsThe current study result recommends that policymakers of Asian countries should create a strong financial environment by implementing that monetary policy that stimulates interest rates in this way that automatically helps to lower down the high ratio of NPLs (tied monitoring system). Liquidity position should be well maintained so that even in a high competition environment, the commercial is able to survive in that environment.Originality/valueThe present paper contributes to the prevailing literature that this is a comparison study between developed and developing countries of Asia that is a unique comparison because the study targets only one region and then on the basis of income, the results of this study are compared. Moreover, the contribution of the study is to include some accounting-based measures and market-based measures of the FP of commercial banks at a time.

Published: October 2021

PurposeCross-cultural studies on differences in eating and consumer behavior have several limitations due to differences between countries, for example, in national health policies. Switzerland combines cultural diversity between the language regions, but with a common national health policy. Therefore, Switzerland provides an ideal framework to investigate cross-cultural eating and consumer behavior. The aim of this study was to combine food consumption, purchase data and sales data to obtain a more comprehensive understanding of cultural dietary differences.Design/methodology/approachSix national Swiss studies on food consumption, one study of food sales from the largest supermarket chain in Switzerland and one national study of food purchasing were included. The estimated marginal mean of each food category in each language region was calculated using linear regression and respective linear random effect models.FindingsIn the French- and Italian-speaking regions more fish was sold, bought and consumed than in the German-speaking region of Switzerland. In contrast, in the German-speaking region, more milk and dairy products were sold, bought and consumed. Language regions explained sales, purchase and consumption of foods, but the findings were only consistent for fish and milk and dairy products.Originality/valueIf possible limitations of cross-culture studies between countries are eliminated, cultural eating and consumer differences are still visible, even in a small country like Switzerland. For the first time, the complexity of studying food consumption, purchasing and sales is shown in one study. This indicates the importance of further studies which consider these three perspectives to better understand cultural differences in eating and consumption behavior.
For all to see: social risk and observable complaining on Facebook
Authors: Armstrong Christine , Kulczynski Alicia , Brennan Stacey 
Published: October 2021

PurposeOnline consumer complaint behaviour that is observable to other consumers provides the firm with an opportunity to demonstrate transparency and service quality to the public eye. The purpose of this paper is to assist practitioners with a strategy to increase perceived accommodativeness in complaint management on social media and reduce the social risk associated with online consumer complaint behaviour using a social exchange theory perspective.Design/methodology/approachSix online experiments with 1,350 US Facebook users were conducted to investigate the effect of supportive and non-supportive virtually present others, and employee intervention on a consumer’s choice to complain, likelihood to make an observable complaint (on the Facebook page) and likelihood to make a non-observable complaint (via Facebook Messenger). The mediating role of perceived accommodativeness and subsequent social risk is also examined.FindingsSupportive comments made to the complainant by virtually present others were found to influence participants’ decision to complain, heighten participants’ likelihood to complain about the Facebook page and reduce their likelihood to complain via Facebook Messenger. This effect was reversed in the presence of non-supportive virtually present others and was explained by perceived social risk. Further, a participant’s likelihood to complain about the Facebook page was increased when an employee intervention was directed at a non-supportive comment made to a complainant, by a virtually present other. This effect was explained by the perceived accommodativeness of the employee interaction.Research limitations/implicationsThe findings advance research on online consumer complaint behaviour by investigating how employee intervention can be used to increase the likelihood of an observable complaint. This research is limited in that it does not incorporate individual characteristics, such as introversion/extroversion and propensity to respond to peer pressure, which may affect participant responses.Practical implicationsThis research shows that perceptions of social risk are most effectively reduced by employee intervention directed at a non-supportive comment (made to a complainant) of a virtually present other. Consumer complaint management strategies aimed at minimising perceptions of social risk and encouraging observable online complaint behaviour are proposed.Originality/valueThis research extends the consumer complaint behaviour taxonomy by introducing the term “observable complaining”, that is, visible complaints made on a Facebook page, and broadens understanding of the organisation’s role in managing non-supportive virtually present others to assuage perceptions of social risk in potential complainants.
Audit committee diversity and corporate scandals: evidence from the UK
Authors: McLaughlin Craig , Armstrong Stephen , Moustafa Maha W. , Elamer Ahmed A. 
Published: October 2021

Purpose
This paper aims to empirically analyse specific characteristics of an audit committee that could be associated with the likelihood of corporate fraud/scandal/sanctions.

Design/methodology/approach
The sample includes all firms that were investigated by the Financial Reporting Council through the audit enforcement procedure from 2014 to 2019, and two matched no-scandal firms. It uses logistic binary regression analysis to examine the hypotheses.

Findings
Results based on the logit regression suggest that audit member tenure and audit committee meeting frequency both have positive associations to the likelihood of corporate scandal. Complementing this result, the authors find negative but insignificant relationships amongst audit committee female chair, audit committee female members percentage, audit committee qualified accountants members, audit committee attendance, number of shares held by audit committee members, audit committee remuneration, board tenure and the likelihood of corporate scandal across the sample.

Research limitations/implications
The results should help regulatory policymakers make decisions, which could be crucial to future corporate governance. Additionally, these results should be useful to investors who use corporate governance as criteria for investment decisions.

Originality/value
The authors extend, as well as contribute to the growing literature on the audit committee, and therefore, wider corporate governance literature and provide originality in that it is the first, to the knowledge, to consider two characteristics (i.e. remuneration and gender) in a UK context of corporate scandal. Also, the results imply that the structure and diversity of the audit committee affect corporate fraud/scandal/sanctions.
A structural equation model for big data adoption in the healthcare supply chain
Authors: Agrawal Dindayal , Madaan Jitender 
Published: October 2021

PurposeThe purpose of this study is to examine the barriers to the implementation of big data (BD) in the healthcare supply chain (HSC).Design/methodology/approachFirst, the barriers concerning BD adoption in the HSC were found by conducting a detailed literature survey and with the expert's opinion. Then the exploratory factor analysis (EFA) was employed to categorize the barriers. The obtained results are verified using the confirmatory factor analysis (CFA). Structural equation modeling (SEM) analysis gives the path diagram representing the interrelationship between latent variables and observed variables.FindingsThe segregation of 13 barriers into three categories, namely “data governance perspective,” “technological and expertise perspective,” and “organizational and social perspective,” is performed using EFA. Three hypotheses are tested, and all are accepted. It can be concluded that the “data governance perspective” is positively related to “technological and expertise perspective” and “organizational and social perspective” factors. Also, the “technological and expertise perspective” is positively related to “organizational and social perspective.”Research limitations/implicationsIn literature, very few studies have been performed on finding the barriers to BD adoption in the HSC. The systematic methodology and statistical verification applied in this study empowers the healthcare organizations and policymakers in further decision-making.Originality/valueThis paper is first of its kind to adopt an approach to classify barriers to BD implementation in the HSC into three distinct perspectives.
A holistic approach towards a more sustainable urban and port planning in tourist cities
Authors: Alberini Carlo 
Published: October 2021

Purpose
This contribution aims to demonstrate that the adoption of a holistic approach to the development of infrastructures supporting the growth of cruise tourism can represent a trigger for a more sustainable urban and port planning in the Moroccan context. Although, along with this growth, there are global-local issues pertaining to sustainability and resilience that need to be addressed to support sustainable urban and social development of tourist cities.

Design/methodology/approach
Documents and literature review were used to develop an in-depth analysis related to the different fields involved in the proposed theoretical reflection. Scientific publications, data and international statistical reports have been used to validate the approach.

Findings
The work provides empirical insights to show the strengths of the country related to the sustainability, suggesting that they deserve to be integrated, involving urban planning, green energy transition, as well as the economic and social sustainability of tourism industry.

Originality/value
This paper aims to stimulate a debate among stakeholders and scholars involved on tourist port cities urban planning to avoid a “silos” approach and to favour a more sustainable infrastructure development process. In that sense, the paper fulfils the need to provide a basis to encourage the integration of different strategic topics and agenda concerning social and economic growth of tourist port cities.
Studying tourist intention on city tourism: the role of travel motivation
Authors: Chi Nguyen Thi Khanh , Phuong Vu Huyen 
Published: October 2021

Purpose
This study aims to investigate the impacts of travel motivations, time perspective and city image that affect travelers’ intention to visit city tourism.

Design/methodology/approach
The data in this study was collected through a structured questionnaire survey conducted in three big cities in the North of Vietnam (Hanoi, Hai Phong and Ha Long). The data set consists of 625 valid responses by Vietnamese tourists. Correlation analysis and structural equation modeling were used to test the causal relationships among time perspective, city image, travel motivations and tourist intention. Confirmatory factor analysis is conducted to verify the reliability and validity of each latent construct and to evaluate the discriminant validity, convergent validity, composition reliability and average variance extracted for the latent constructs.

Findings
This study finds that tourists’ travel motivations, time perspective and city image are significantly and positively associated with their intention to visit city tourism. This study also reports that tourists’ time perspective and city image are significantly and positively related to their travel motivation which is in turn significantly and positively correlated to their intention to engage in city tourism.

Practical implications
City tourism providers need to seek for understanding travel motivations of potential customers. City tourism products should be promoted to people who want to travel for knowledge enhancement, seeking, self-fulfillment, socializing and escape. Tourism businesses and marketers focus more on developing the overall image of city. They should have city slogan and have strategy to establish the city branding to evoke or remind the customers to come in. Since the Corona (COVID-19) pandemic impact on every nation around the world, the artificial intelligence has to be taken on city tourism to minimize the negative influence of this pandemic.

Originality/value
This study reveals three key determinants of tourists’ intention including travel motivations, city image and time perspective, which have unclear study in the city tourism literature. This study also explains the role of travel motivations in mediating the impacts of their time perspective and city image on their intention to visit city tourism. Improving the city image is important to attract tourists who want to engage in city tourism for knowledge enhancement, seeking, self-fulfillment, socializing or escape. Tourism providers need to have a strategy for establishing the city branding to evoke or remind the customers to come in. The time perspective should be paid more attention to tourists who want to travel to city tourism for knowledge enhancement, seeking, self-fulfillment, socializing or escape.
An empirical study of sustainability reporting assurance: current trends and new insights
Authors: Alsahali Kholod Fahad , Malagueño Ricardo 
Published: October 2021

Purpose
This study aims to examine trends in the global assurance practices of sustainability reports, updating and broaden the extant literature and proving new insights that could guide future research.

Design/methodology/approach
The data were collected for 12,783 companies and exploratory descriptive analyses of sustainability reporting assurance practices were undertaken.

Findings
The study shows that assurance growth is lagging behind the growth in sustainability reporting. It reveals that assurer switching is a common practice amongst companies. There is an increasing trend towards the use of the International Standard for Assurance Engagements 3000 by non-accounting assurers. Additionally, in terms of assurance providers, the study finds that accounting firms are dominating the market, however, engineering firms are fast increasing their share of the sustainability assurance market, whilst consulting firms’ share is decreasing. However, the switch towards consulting firms is higher than the switch towards accounting firms in the last switch period.

Practical implications
Overall, the results of this study provide insights about companies’ assurance practices for regulators, assurance providers and companies interested in assuring their sustainability reports.

Social implications
This study is relevant for companies’ stakeholders, including investors, to enhance their understanding of companies’ current assurance practices.

Originality/value
Prior studies on the assurance practices of sustainability reports are limited in scope (concentrate on large companies) and depth (examine accounting vs non-accounting assures and consider the evolving patterns at the institutional rather than firm-level). This study presents developments and trajectories of assurance practices to inform researchers and practitioners on the global trends by bringing an updated and broader perspective on the topic.
