AbstractWith frequent host shifts involving the colonization of new hosts across large geographical ranges, crop pests are good models for examining the mechanisms of rapid colonization. The microbial partners of pest insects may also be involved in or affected by colonization processes, which has been little studied so far. We investigated the demographic history of the rosy apple aphid,Dysaphis plantaginea, a major pest of the cultivated apple (Malus domestica) in Europe, North Africa and North America, as well as the diversity of its microbiota. We genotyped a comprehensive sample of 714 colonies from Europe, Morocco and the US using mitochondrial (CytBandCO1), bacterial (16s rRNA andTrnpB), and 30 microsatellite markers. We detected five populations spread across the US, Morocco, Western and Eastern Europe and Spain. Populations showed weak genetic differentiation and high genetic diversity, except the ones from Morocco and North America that are likely the result of recent colonization events. Coalescent-based inferences revealed high levels of gene flow among populations during the colonization but did not allow determining the sequence of colonization of Europe, North America and Morroco byD. plantaginea, likely because of the weak genetic differentiation and the occurrence of gene flow among populations. We found thatD. plantagineararely hosts other endosymbiotic bacteria than its obligate nutritional symbiontBuchnera aphidicola. This suggests that secondary endosymbionts did not play an important role in the rapid spread of the rosy apple aphid. These findings have fundamental importance for understanding pest colonization processes and implications for sustainable pest control programs.

AbstractBile salt synthesis, secretion into the intestinal lumen, and resorption in the ileum occurs in all vertebrate classes. In mammals, bile salt composition is determined by host and microbial enzymes, affecting signaling through the bile salt-binding transcription factor Farnesoid X receptor (Fxr). However, these processes in other vertebrate classes remain poorly understood. We show that key components of hepatic bile salt synthesis and ileal transport pathways are conserved and under control of Fxr in zebrafish. Zebrafish bile salts consist primarily of a C27bile alcohol and a C24bile acid which undergo multiple microbial modifications including bile acid deconjugation that augments Fxr activity. Using single-cell RNA sequencing, we provide a cellular atlas of the zebrafish intestinal epithelium and uncover roles for Fxr in transcriptional and differentiation programs in ileal and other cell types. These results establish zebrafish as a non-mammalian vertebrate model for studying bile salt metabolism and Fxr signaling.
An integrative and conjugative element encodes an abortive infection system to protect host cells from predation by a bacteriophage
Authors: Johnson Christopher M. , Harden M. Michael , Grossman Alan D. 
Published: December 2020

AbstractBacteriophages and integrative and conjugative elements (ICEs, a.k.a. conjugative transposons) are mobile genetic elements that can move from one bacterial cell to another and often coexist in a host genome. Many bacterial species contain at least one temperate (lysogenic) phage and an integrative and conjugative element. Most strains ofBacillus subtilisare lysogenic for the phage SPß and also contain the integrative and conjugative element ICEBs1. We found that the presence of ICEBs1in cells inhibited production of SPß, during both activation of a lysogen and followingde novoinfection. The ICEBs1geneyddK (renamedspbKfor SPß killing) was both necessary and sufficient for the anti-SPß activity. Co-expression ofspbKandyonE, in the absence of other ICEBs1and SPß genes, resulted in inhibition of cell growth and loss of cell viability. These results indicate that togetherspbKandyonEaffected a host process needed for normal growth and thatspbKconstitutes an abortive infection system. We found that this anti-SPß phenotype protected populations ofB. subtilisfrom predation by SPß, likely providing selective pressure for the maintenance of ICEBs1inB. subtilispopulations. spbKencodes a TIR (Toll-interleukin-1 receptor)-domain protein with similarity to both plant antiviral proteins and animal innate immune signaling proteins. We postulate that selective many uncharacterized cargo genes in ICEs may confer selective advantage to cells by protecting against other mobile elements.

Authors: Alcorn Michelle R. , Vega Daniel , Irvin Ryan , Paez Paola 
Published: December 2020

PurposeAs exploratory research, this project aimed to develop and assess the effect of implementing a food waste reduction program at a restaurant on a university campus.Design/methodology/approachData collection consisted of an audit of both pre and postconsumer food waste to determine the effectiveness of various reduction strategies and a survey to assess attitudes of employees toward food waste. As exploratory research, a personalized database was created to track current food waste amounts and reasons for waste in the restaurant operation to determine if the same method could be employed in future research.FindingsOverall, the restaurant in this study implemented various effective food waste reduction practices that were inexpensive and simple, resulting in a weekly average reduction of 14.3 pounds of food waste. The top five food item products wasted by the kitchen were also identified for both pre and postintervention phases as well as the reasons for generating kitchen waste. Furthermore, data reported on postconsumer waste included weight quantities and product types.Originality/valueThe project resulted in evidence that a personalized food tracking system is useful for identifying and quantifying food waste in foodservice operations. Therefore, the research design and data collection methods used in this project can be used in future research on a larger scale.
Technology management for innovation in organizations: an argumentation-based modified TISM approach
Authors: Rajan Rishabh , Dhir Sanjay , Sushil  
Published: December 2020

PurposeIn the rapidly changing business world, innovation plays a vital role for organizations to gain a competitive advantage. Various factors associated with technology management and innovations in organizations are diverse in the existing literature. Therefore, there is a need to bridge these gaps in the fitting proportions toward innovations within organizations. The primary objective of this study is to identify, explain and interpret the relationships between the identified technology-related factors that are important for innovations in organizations.Design/methodology/approachIn this study, a modified total interpretive structural modeling (M-TISM) methodology was used to examine and analyze the various interactions between identified factors for innovations in organizations. However, the argumentation of the links is relatively weak in M-TISM. In order to compensate for this, M-TISM is additionally altered by an “Argumentation-based Modified TISM”. Hence, this research strengthens the modified TISM methodology by incorporating argumentation and total interpretation of the relationships between the identified factors.FindingsA total of six major factors were identified using a literature review. Results suggest that workforce technical skills, technological infrastructure, technological alliances, technology transfer and top management support have an impact on innovation in organizations. Results also suggest that top management support and the technological infrastructure of an organization have a greater impact on innovation.Research limitations/implicationsFor policymakers and practitioners, this study provides a suggestive list of critical factors, which may help to develop policies or guidelines for improving innovation in organizations. Policymakers should focus on technological infrastructure and collaborations to enhance innovations and productions within the organizations. For academicians, this study provides a modified TISM model that shows the impact of technology-related factors on innovations. Future researchers could expand this study by adding a greater number of technological factors and validate this model in other industries.Originality/valueThis study fills a gap in the literature by interpreting the various relationships among the identified factors and innovations. The model has been validated through a panel of seven experts from the Indian automotive industry of multiple organizations. This study is useful in the automobile industry as it determines what and how technology-related factors affect innovations, process improvement and R&D production for organizations.
Ethical disclosure in the Shari’ah annual reports of Islamic banks: discourse on Shari’ah governance, quantitative empirics and qualitative analysis
Authors: Sencal Harun , Asutay Mehmet 
Published: December 2020

PurposeAs an essential component of Islamic governance for ensuring religious compliance, Shari’ah annual reports (SARs) play an important role in providing communication between Shari’ah board (SB) members and stakeholders. This paper aims to determine the ethical disclosure in SARs to identify how close the Shari’ah disclosure to the standards set by AAOIFI and also substantive morality of Islam. The research also aims to examine the factors determining disclosure performance.Design/methodology/approachTwo disclosure indices are developed to generate data from the SARs: the AAOIFI standards for Shari’ah governance index for form related approach, an Islamic ethicality augmented index reflecting on substantive morality approach. The sample consists of 41 Islamic banks from 15 different countries for the period of 2007–2014. Sampled 305 SARs were examined through disclosure analysis in line with the two indices developed for this study. The econometric analysis was run to identify the factors determining disclosure performance.FindingsThe findings suggest that AAOIFI guidelines have an influence on the level of disclosure, even if Islamic banks have not adopted them. However, the level of disclosure for the ethically augmented index is found to be very limited with reliance on general statements in most of the cases. As part of determining factors, the popularity of Shari’ah scholars is significant for both indices, while the existence of an internal Shari’ah auditing department holds some explanatory power. The adoption of AAOIFI standards at the country level, the regulatory quality and the duration of Sharīʿah-compliance are particularly deterministic factors in terms of complying with AAOIFI standards for SARs.Originality/valueAlthough SB is the most crucial division of corporate governance in Islamic banks in terms of securing the “Islamic” identity of these institutions, their most important communication instrument, namely, SAR, has not been explored sufficiently, alongside an insufficient attempt to constitute Islamic corporate governance. Initially, this study attempted to constitute an Islamic corporate governance framework as a theoretical construct, which provides context for the empirical part of the research and this should be considered a novel approach. Second, the empirical part of the research aims to fill the gap observed in the literature such as small sample size and index construction-related matters. This research is conducted with a larger sample size as compared to the available studies in the literature and it has developed two indices for disclosure analysis along with developing an Islamic morality-based index beside an index based on AAOIFI standards.

Published: December 2020

PurposeThis study was designed to specifically explore confirmation and perceived usefulness associated with mobile food ordering apps (MFOAs) in consideration of their impacts upon attitudes, satisfaction and intention to continuously use.Design/methodology/approachThe research utilized the convenience sampling to gather data from 250 respondents having prior experience with MFOAs during COVID-19 pandemic period in Bangladesh. The Structural Equation Modeling technique was applied to analyze the data using SmartPLS 3 software.FindingsThis study's results showed that customers' perceived confirmation and usefulness were significant in determining their dinning attitudes. Besides, customers' dining attitudes were positively related to e-satisfaction. Finally, the customers’ continuance intention to use MFOAs was significantly influenced by their e-satisfaction.Research limitations/implicationsRestaurants managers should focus on online sales through MFOAs during the pandemic period since social distancing is a key strategy to manage COVID-19. Customers should be assured that the safety measures are undertaken while delivering the food.Originality/valueThis study incorporated the expectation-confirmation theory and technology acceptance model and tested it in the context of MFOAs.
Hospitality-based service recovery, outcome favourability, satisfaction with service recovery and consequent customer loyalty: an empirical analysis
Authors: Shams Ghazal , Rather Raouf , Abdur Rehman Mohsin , Lodhi Rab Nawaz 
Published: December 2020

Purpose
In recent studies, tourism scholars focussed more on service failure and recovery. Thus satisfaction with service recovery (SSR) and outcome favourability in conjunction with service recovery (SR) and customers’ behavioural intention was given very little attention, while they are very attention-grabbing, particularly in marketing areas of hospitality and tourism studies. Using stealing thunder and co-creation-based strategies, this study aims to investigate the impact of SR on outcome favourability, and its association with SSR and customer loyalty.

Design/methodology/approach
To attain the objectives of the current study, data were collected through field survey by applying a random sampling technique from 346 regular customers four- and five-star hotels in the context of Iran. The structural equation modelling technique was applied for testing the measurement and relationship models of the study.

Findings
The findings of this research reveal a positive relationship between SR and outcome favourability. The findings also indicate that outcome favourability positively affects SSR and loyalty. Finally, SSR exerts a favourable and significant impact on customer loyalty.

Research limitations/implications
The study findings may have restricted applicability in different contexts other than four- and five-star hotels. Theoretically, the current research contributes insight into the dynamics of characterizing SR, outcome favourability, SSR and behavioural intention-based theoretical associations, as observed in the hospitality industry.

Originality/value
This study adopted an un-explored SR, outcome favourability and SSR theoretical perspectives to identify the strength and nature of relationships between them and discuss their important implications for academicians and hotel managers.
Guiding factors for planning public open spaces to enhance coastal cities’ disaster resilience to tsunamis
Authors: Jayakody R.R.J. Chathuranganee , Amaratunga Dilanthi 
Published: December 2020

Purpose
Public open spaces (POS) in cities are often measured as a strength to enhance cities’ sustainability with a contribution to the three pillars: economic, social and environmental. Nevertheless, the importance of POS for disaster resilience is less recognised and remains under-rehearsed in the urban planning context. Within this context, this research paper aims to investigate the methods and approaches of using POS to enhance the coastal cities’ resilience to tsunamis through planning and designing interventions.

Design/methodology/approach
This study used the grounded theory as the research strategy. Accordingly, data collection involved 72 unstructured interviews covering a wide variety of participants related to the field of study including tsunami-affected communities, disaster resilience experts, urban planners, sociologists and coastal planners, in the context of Sri Lanka. The grounded theory coding procedure is used to analyse the data that includes transcripts, notes, maps and documents.

Findings
The analysis reveals that there is a significant potential to use POS to enhance the coastal cities’ resilience to tsunamis as an emergency evacuation directing point, as a primary place for emergency rescue, as an agent for temporary sheltering, as a facilitator for tsunami disaster mitigation and as a mediator to provide tsunami awareness. Finally, the findings propose five guiding factors for planning POS to enhance coastal cities’ disaster resilience to Tsunamis.

Originality/value
This paper introduces an innovative and unique approach for future urban planners and design professionals, to plan and design POS with a new direction towards disaster resilience while ensuring sustainability.
Bilateral trade agreements and trade finance: evidence from Turkey
Authors: Habiyaremye Alexis , Avsar Veysel 
Published: December 2020

PurposeThis study investigates the impact of trade integration on payment choice in international transactions using data from Turkey, an emerging economy that signed many trade agreements in the last two decades.Design/methodology/approachThe authors use industry-level trade finance data from Turkey, which reports payment methods in exports at two-digit ISIC level for 180 export destinations. The authors performed linear as well as maximum likelihood techniques to test our hypothesis.FindingsThe authors show that the removal of trade barriers by bilateral free trade agreements leads to more exporter-financed transactions. This implies that lowering trade barriers contributes to reducing risk, which leads to more trade finance by exporters.Originality/valueTrade finance is the lifeblood of global trade. Although the previous literature have analyzed the institutional and financial factors affecting exporters' decision to extend trade credit, the effect of economic integration has been overlooked. In this regard, this study represents the first attempt to analyze the impact of trade integration on trade finance.
Impact of external assurance on corporate climate change disclosures: new evidence from Finland
Authors: Dutta Probal , Dutta Anupam 
Published: December 2020

PurposeThe purpose of this research is to examine the impact of external assurance on the level of voluntary corporate climate change disclosures by Finnish firms.Design/methodology/approachThe sample of this study includes 228 firm-year observations over the period 2008–2015 for listed Finnish companies that have issued sustainability reports and responded to the Carbon Disclosure Project (CDP) questionnaire at least once during the sample period. The authors conduct a panel regression analysis to study the afore-mentioned linkage. In addition, the Tobit regression model is also estimated to check the robustness of our findings.FindingsThe findings suggest that assurance has a highly significant positive impact on the level of corporate climate change disclosures even after controlling for the effect of a number of control variables. Moreover, among the control variables, firm size and asset age are found to have significant effect on the extent of carbon emissions disclosure. Furthermore, the additional analysis reveals that the type of assurance providers (accounting firms vs non-accounting firms) and the type of financial auditors (Big4 financial auditors vs non-Big4 financial auditors) do not influence the level of climate change disclosure of assured companies.Research limitations/implicationsThis research is subject to certain limitations. First, the source of the data used in this research is the CDP database which has limitations in that it is a voluntary disclosure process where all the observations collected are self-reported by the responding firms. This may bias the reported findings. Second, our sample includes only listed companies and hence the results might have limited explanatory capacity for unlisted firms.Practical implicationsBy using the results of this research, corporate managers will be able to reduce the information asymmetry between various stakeholders and them through disclosure of accurate, reliable and credible environmental information. Such disclosures will, in turn, allow socially responsible investors to choose eco-friendly investments and will thus enable them to make appropriate investment decisions.Originality/valueResearch on the external assurance-corporate climate change disclosure nexus is scarce. This study addresses this gap in the nonfinancial disclosure assurance literature by demonstrating that external assurance increases the level of voluntary corporate climate change disclosure. Drawing on stakeholder-agency theory, this study views external assurance as a monitoring structure that potentially curbs the monitoring problem between corporate managers and other stakeholders and increases the amount of climate change disclosures making a possible avenue for the reduction of the information asymmetry between them.
