AbstractVibrio choleraeis a natural inhabitant of aquatic ecosystems worldwide, typically residing in coastal or brackish water. While more than 200 serogroups have been identified, only serogroups O1 and O139 have been associated with epidemic cholera. However, infections other than cholera can be caused by nonepidemic, non-O1/non-O139V.choleraestrains, including gastroenteritis and extraintestinal infections. WhileV.choleraecan also survive in freshwater, that is typically only observed in regions of the world where cholera is endemic. We recently isolatedV.choleraefrom several locations in lakes and rivers in northwest Ohio. These isolates were all found to be non-O1/non-O139V.choleraestrains, that would not cause cholera. However, these isolates contained a variety of virulence genes, includingctxA, rtxA, rtxC, hlyA, andompU. Therefore, it is possible that some of these isolates have the potential to cause gastroenteritis or other infections in humans. We also investigated the relative motility of the isolates and their ability to form biofilms as this is important forV.choleraesurvival in the environment. We identified one isolate that forms very robust biofilms, up to 4x that of our laboratory control strains. Finally, we investigated the susceptibility of these isolates to a panel of antibiotics. We found that many of the isolates showed decreased susceptibility to some of the antibiotics tested, which could be of concern. While we do not know if these isolates are pathogenic to humans, increased surveillance to better understand the public health risk to the local community should be considered.ImportanceThis study found thatVibrio choleraebelonging to non-O1/non-O139 serogroups is present in freshwater lakes and rivers in northwest Ohio. Although non-O1/non-O139V.choleraestrains generally do not produce cholera toxin, and thus do not cause epidemic cholera, they often contain other virulence factors that may contribute to pathogenicity. In fact, we found that these local isolates contained an assortment of potential virulence genes. We also found that some of the isolates showed antibiotic resistance. While we do not currently know if the localV.choleraestrains are capable of causing disease in humans, increased monitoring forV.choleraein the region is warranted in the interest of public health.
We shall meet again - Genomics of historical admixture in the sea
Authors: Feng Xueyun , Merilä Juha , Löytynoja Ari 
Published: May 2020

AbstractWe studied the impact of genetic introgression in evolution and on evolutionary studies with whole-genome data from two divergent lineages of sticklebacks. Our results reveal that the hybrid zone between the lineages ranges across the entire Baltic Sea and parts of the North Sea with the foreign ancestry decreasing with increasing distance to the source population. Introgression has also penetrated currently isolated freshwater populations. We identified footprints of selection on regions enriched for introgressed variants, suggesting that some of the introgression has been adaptive. However, the levels of introgression were in general negatively correlated with the recombination rate, suggesting that the introgression has been largely neutral and adaptive ancestral standing variation likely had a more important role in shaping the genomic landscape. Our results further suggest that overlooked introgression can mislead analyses of local adaptation and phylogenetic affinities, highlighting the importance of accounting for introgression in studies of local adaptation.
Collaborative design of an active learning classroom with high school students and teachers
Authors: Kepez Orcun , Ust Selin 
Published: May 2020

PurposeThe aim of this study is to understand classroom settings desired by high school students and teachers in an active learning classroom. The research question is whether students and teachers will differ from each other when designing an active learning classroom.Design/methodology/approachIn an effort to design a learning environment for an advanced placement programme, action research methodology was followed by conducting a participatory workshop in a real active learning classroom with future users. Working in isolation from one another, students and teachers designed their own classrooms by forming different learning centres. During the study, two groups, made up of ten high school students and seven teachers, respectively, were asked to arrange the furniture in an active learning classroom. The groups were free to form as many furniture arrangement configurations as they wished and were asked to write about their workshop experiences afterwards. Once they had completed both tasks, their plan layouts were examined.FindingsAll of the plan layouts were found to fall into one of three categories: a traditional layout, a small group layout or a single large group layout. The written texts were also analysed, which revealed different perspectives of each participating group. As students and teachers explore different learning opportunities, they appear to be driven by different kinds of experiences when they endeavour to organize their classrooms.Originality/valueNever before has an active learning classroom been the site for a participatory furniture arrangement workshop that employs teachers and students.
Improving human–robot interactions in hospitality settings
Authors: Collins Galen R. 
Published: May 2020

PurposeService robotics, a branch of robotics that entails the development of robots able to assist humans in their environment, is of growing interest in the hospitality industry. Designing effective autonomous service robots, however, requires an understanding of Human–Robot Interaction (HRI), a relatively young discipline dedicated to understanding, designing, and evaluating robotic systems for use by or with humans. HRI has not yet received sufficient attention in hospitality robotic design, much like Human–Computer Interaction (HCI) in property management system design in the 1980s. This article proposes a set of introductory HRI guidelines with implementation standards for autonomous hospitality service robots.Design/methodology/approachA set of key user-centered HRI guidelines for hospitality service robots were extracted from 52 research articles. These are organized into service performance categories to provide more context for their application in hospitality settings.FindingsBased on an extensive literature review, this article presents some HRI guidelines that may drive higher levels of acceptance of service robots in customer-facing situations. Deriving meaningful HRI guidelines requires an understanding of how customers evaluate service interactions with humans in hospitality settings and to what degree those will differ with service robots.Originality/valueRobots are challenging assumptions on how hospitality businesses operate. They are being increasingly deployed by hotels and restaurants to boost productivity and maintain service levels. Effective HRI guidelines incorporate user requirements and expectations in the design specifications. Compilation of such information for designers of hospitality service robots will offer a clearer roadmap for them to follow.
Solar energy policy to boost Brazilian power sector
Authors: Barbosa Juliana Pacheco , Saraiva Joisa Dutra , Seixas Julia 
Published: May 2020

Purpose
The purpose of this paper is to highlight the opportunity for the energy policy in Brazil to tackle the very high cost-effectiveness potencial of solar energy to the power system. Three mechanisms to achieve ambitious reductions in the greenhouse gas emissions from the power sector by 2030 and 2040 are assessed wherein treated as solar targets under ambitious reductions in the greenhouse gas emissions from the power sector. Then, three mechanisms to achieve these selected solar targets are suggested.

Design/methodology/approach
This paper reviews current and future incentive mechanisms to promote solar energy. An integrated energy system optimization model shows the most cost-efficient deployment level. Incentive mechanisms can promote renewable sources, aiming to tackle climate change and ensuring energy security, while taking advantage of endogenous energy resources potential. Based on a literature review, as well as on the specific characteristics of the Brazilian power system, under restrictions for the expansion of hydroelectricity and ambitious limitation in the emissions of greenhouse gases from the power sector.

Findings
The potential unexploited of solar energy is huge but it needs the appropriate incentive mechanism to be deployed. These mechanisms would be more effective if they have a specific technological and temporal focus. The solar energy deployment in large scale is important to the mitigation of climate change.

Originality/value
The value of the research is twofold: estimations of the cost-effective potential of solar technologies, generated from an integrated optimization energy model, fully calibrated for the Brazilian power system, while tacking the increasing electricity demand, the expected reduction of greenhouse gas emissions and the need to increase the access to clean and affordable energy, up to 2040; proposals of three mechanisms to deploy centralized PV, distributed PV and solar thermal power, taking the best experiences in several countries and the recent Brazilian cases.
Segmentation of defects in textile fabric with robust texture representation and total variation
Authors: Zhou Jian , Liu Jianli 
Published: May 2020

PurposeVisual quality control on raw textile fabrics is a vital process in weaving factories to ensure their exterior quality (visual defects or imperfection) satisfying customer requirements. Commonly, this critical process is manually conducted by human inspectors, which can hardly provide a fast and reliable inspection results due to fatigue and subjective errors. To meet modern production needs, it is highly demanded to develop an automated defect inspection system by replacing human eyes with computer vision.Design/methodology/approachAs a structural texture, fabric textures can be effectively represented by a linearly summation of basic elements (dictionary). To create a robust representation of a fabric texture in an unsupervised manner, a smooth constraint is imposed on dictionary learning model. Such representation is robust to defects when using it to recover a defective image. Thus an abnormal map (likelihood of defective regions) can be computed by measuring similarity between recovered version and itself. Finally, the total variation (TV) based model is built to segment defects on the abnormal map.FindingsDifferent from traditional dictionary learning method, a smooth constraint is introduced in dictionary learning that not only able to create a robust representation for fabric textures but also avoid the selection of dictionary size. In addition, a TV based model is designed according to defects' characteristics. The experimental results demonstrate that (1) the dictionary with smooth constraint can generate a more robust representation of fabric textures compared to traditional dictionary; (2) the TV based model can achieve a robust and good segmentation result.Originality/valueThe major originality of the proposed method are: (1) Dictionary size can be set as a constant instead of selecting it empirically; (2) The total variation based model is built, which can enhance less salient defects, improving segmentation performance significantly.

Additional questions include how priming encourages healthy behaviors, what promotes healthy workplace cultures and what social marketing appeals promote healthy behaviors.Practical implicationsSenior managers can implement findings to create effective wellness programs benefiting employees and firms through improved employee health and productivity and reduced corporate health-care costs.Social implicationsEffective wellness programs reduce overall health-care costs for society and provide improved participants’ quality of work, personal and family life.Originality/valueThis research uniquely applies internal marketing, social marketing and marketing exchange concepts to best practices from the wellness literature and applies these to recommendations for effective corporate-based wellness programs.
The effects of CARTER model on attitudinal loyalty in Islamic banks
Authors: Dandis Ala' Omar , Wright Len Tiu 
Published: May 2020

Purpose
The purpose of this paper is to investigate how the CARTER model impact on attitudinal loyalty in Islamic banks.

Design/methodology/approach
The paper presents primary data collected by self-administered questionnaires involving a sample of 655 respondents from all local Islamic banks in Jordan. SPSS was used to analyse the data and AMOS was used to analyse confirmatory factor analysis.

Findings
In terms of the dimensions of CARTER model, the results show that empathy, assurance and compliance are the most influential factors leading to attitudinal loyalty. Insignificant relationship between tangibles and attitudinal loyalty was found. The findings also show that customer satisfaction plays as a mediating variable between dimensions of service quality and attitudinal loyalty.

Practical implications
Islamic banks should focus on continuous improvement of service quality because of the direct effect on attitudinal loyalty. Managers should pay special attention to the quality provided by their employees and develop their skill set through training and education programmes using Islamic knowledge. They should make sure that all activities are carried out in the right manner the first time and every time to enhance customer loyalty at all times. They also are recommended to comply with the Shariah board alliances and collaboration and other decisions of the Islamic Fiqh Academy.

Originality/value
As the first study of its kind in Jordan, the paper’s contribution stems from filling the research gap in examining the effects of the various service quality dimensions on the impact of attitudinal loyalty in Islamic banks using the CARTER model.
Metaphors we manage and develop quality by
Authors: Lilja Johan , Ingelsson Pernilla , Snyder Kristen , Bäckström Ingela , Hedlund Christer 
Published: May 2020

Purpose
Metaphors are a powerful and human way of understanding and experiencing one kind of thing in terms of another. In quality management (QM), several metaphors are used to describe and bring to life the often-abstract QM concepts and systems. These metaphors are of great importance for how QM is understood, communicated and practiced. However, the metaphors of QM have seldom been systematically screened or put in focus, neither the topic of a critical discussion. The purpose of this paper is hence to contribute with a screening of the metaphors currently used, within QM literature and in practice among QM leaders, and then elaborate on their potential for improvement and development.

Design/methodology/approach
The paper is based on a literature review combined with interviews of QM leaders.

Findings
The paper highlights that the current QM metaphors provide intuitive associations to properties such as stability, shelter, and structure, but not to the important dynamic properties of QM, such as learning, or to the critical role of people in QM. What can be seen as core properties of QM are communicated by texts or labels added on to metaphors with properties that often are in sharp contrast to them. The paper also provides suggestions for further improvements and development.

Originality/value
The paper highlights the area of metaphors within QM as an important area for future research. It also provides insights concerning the successful use and selection of metaphors in future QM practice.
Facebook and the cultivation of ethnic diversity perceptions and attitudes
Authors: Hermann Erik , Eisend Martin , Bayón Tomás 
Published: May 2020

PurposeThe purpose of this paper is to apply cultivation theory to social network sites by investigating how Facebook uses cultivates users' ethnic diversity perceptions and attitudes.Design/methodology/approachThe authors’ investigations include an online and offline survey study with 476 Facebook users and a follow-up experiment with 75 individuals.FindingsThe authors provide empirical support that Facebook use cultivates ethnic diversity perceptions and ethnic diversity-related attitudes. They show that Facebook use relates to perceptions of ethnic minorities that resemble the world on Facebook that is characterized by high ethnic diversity. The authors further demonstrate that the cultivation of ethnic diversity-related attitudes is mediated by diversity perceptions related to users' close social environment.Research limitations/implicationsFuture research should consider culturally and educationally diverse samples as well as longitudinal research designs to address external validity and causality issues.Practical implicationsAlgorithms determining the content users are exposed should be thoughtfully curated to avoid attitudinal and ideological polarization.Social implicationsFacebook can play an important role in positively shaping intergroup relations, thereby countering negative outgroup attitudes, social anxieties and radical right-wing parties.Originality/valueThe authors’ studies extend the scope of cultivation research by identifying a new media vehicle as a source of cultivation influences and shed light on the cultivation-based process of attitude change on social network sites.
Employee championing behavior in the context of organizational change: a proposed framework for the business organizations in Bangladesh
Authors: Islam M. Nazmul , Furuoka Fumitaka , Idris Aida 
Published: May 2020

PurposeThe purpose of this paper is to propose a conceptual framework for ensuring employee championing behavior (ECB) during organizational change for business organizations in Bangladesh.Design/methodology/approachOn the basis of previous literature, this paper proposed a framework for ensuring ECB during organizational change.FindingsThis paper proposed transformational leadership (TL), which enhances the championing behavior of the employee. In addition, valence, work engagement and trust in leadership act as potential mediators between TL and championing behavior. This paper also proposed organizational alignment (OA) as a potential moderator that influences ECB in the context of organizational change.Research limitations/implicationsThis paper highlights numerous influential factors that enhance ECB. This proposed conceptual framework will be validated by the empirical evidence in future research.Practical implicationsThis paper provides new insights for business leaders to understand the importance of ECB during organizational change. Moreover, this research underlined the effectiveness of valence, work engagement and trust in leadership and OA to nurture ECB in the time of organizational change, which helps managers of the business organizations to make efficient strategies to tackle organizational change.Originality/valueThis paper adopted Kurt Lewin’s change management theory and integrated with different factors associated with organizational change (TL, valence, work engagement, trust in leadership and OA) to propose a model to understand the mechanism of enhancing ECB in the context of change in Bangladesh’s business organizations.
The role online review on mobile commerce adoption: an inclusive growth context
Authors: Pipitwanichakarn Tanikan , Wongtada Nittaya 
Published: May 2020

Purpose
As technology has increasingly disrupted traditional commerce, there is a need for inclusive growth to ensure that no group – particularly the underprivileged – is left behind. Against this backdrop, this paper aims to shed light on mobile commerce (m-commerce) adoption among street vendors. This study conducts an experiment to investigate the contribution of online reviews and relevant factors in enhancing the perceived usefulness and adoption of m-commerce.

Design/methodology/approach
This study used a 2 (perceived ease of use: high vs low) × 2 (trust in service provider: high vs low) × 2 (online review: positive vs negative) between-subjects design, resulting in eight experimental groups. The level of the online review was manipulated, and the degrees of perceived ease of use and trust were measured.

Findings
Perceived usefulness depends on online reviews when users perceive incongruent information (e.g. high ease of use but low trust); that is, users who saw positive reviews more strongly perceived the usefulness of m-commerce. On the contrary, perceived usefulness does not vary based on online reviews if users perceive congruent information (e.g. high ease of use and high trust).

Originality/value
This research advances the knowledge of m-commerce adoption by exploring the interaction of perceived ease of use, trust and online reviews, a combination that has not been addressed in previous empirical studies.
