How ostracism jeopardizes customers' interests at restaurants: a study in context of COVID-19
Authors: Sarwar Ambreen , Abdullah Muhammad Ibrahim , Imran Muhammad Kashif , Rafiq Nazia 
Published: July 2022

PurposeWith theoretical underpinnings in the conservation of resources theory, this research aims at understanding the link between workplace ostracism (WPO) and its effects on customers' interests in the context of COVID-19, with the mediation of stress and moderation of self-efficacy (SE).Design/methodology/approachThe study followed a time-lagged design. A sample of 217 frontline employees working in the food sector of southern Punjab, Pakistan, responded to the study questions using the survey method with structured questionnaires. A Statistical Package for the Social Sciences (SPSS) tool was utilized for data analysis with bootstrapping and PROCESS macro.FindingsThe findings show that an important mechanism by which ostracism translates into customer service sabotage (CSS) is the increase in perceived stress levels of the employees. Additionally, SE was found to be an important personal resource that acts as a moderator in the said relationship.Practical implicationsEmployees with high SE sense less workplace stress even during a pandemic. Leadership should consider the stress-alleviating effect of SE for lessening the damaging influence of WPO on customers.Originality/valueThe study fills an important empirical gap in the context of the COVID-19 pandemic, by showing that due to resource loss perceived by employees while being targeted by ostracism, they may decide to transfer their frustration towards organizational customers by sabotaging their service experience.
Entrepreneurial marketing orientation of the Polish and Finnish SMEs and its environmental determinants
Authors: Kowalik Izabela , Danik Lidia , Pleśniak Agnieszka 
Published: July 2022

Purpose
The entrepreneurial marketing orientation (EMO) has been studied primarily in developed countries. The past research has focused on entrepreneurial marketing dimensions and their relationship with selected small- and medium-sized firm (SME) activities, strategic orientations or performance. Scholars have not paid enough attention to the EMO determinants. This study aims to investigate whether the SMEs originating from different countries, including the post-transition market, differ in their entrepreneurial marketing approach and checks its external determinants connected with environmental turbulence.

Design/methodology/approach
A total of 219 Polish and 81 Finnish manufacturing SMEs, serving mainly business-to-business clients, were surveyed using the mixed-mode computer assisted telephone interview/computer assisted web interview method between 2020 and 2021. Structural equation modelling, multigroup confirmatory factor analysis analysis, analysis of variance and T-tests were applied.

Findings
The metric and partial scalar invariance of the EMO scale used in Finland and Poland was found. The authors showed that Finnish firms represent a more robust entrepreneurial posture in marketing than Polish ones. The export market turbulence and the perceived crisis influence are the environmental determinants of EMO level, while the industry technological development level is not.

Research limitations/implications
The conducted analyses allowed to identify EMO determinants, verify the entrepreneurial marketing measurement concept in a new country (Finland) and show the differences in EMO between SMEs from a less and more developed country.

Originality/value
The existing literature lacks empirical data on the external EMO determinants and inter-country comparisons. This study shows the differences in EMO level of companies from different country backgrounds and points to the market turbulence as its determinant.
How digital fabrication technologies within digitalized innovation environments lead to participative aid development
Authors: Hellwig Lukas , Preissner Lisa , Pawlowski Jan , Deiters Wolfgang 
Published: July 2022

PurposeFacilities such as FabLabs and Makerspaces are characterized by the facilities' wide range of digital fabrication technologies as well as facilities' interdisciplinary user base and collaborative problem solving and product development. These possibilities can also hold great potential for people with disabilities who have a specific need for assistive technology. Since there are no established models of such participatory development processes (PDP) within digitalized innovation environments (DIE), this study intends to provide a comprehensive understanding of these processes along with the influencing factors.Design/methodology/approachThrough a cooperation with a Thalidomide Association, various PDPs were accompanied within a DIE and interviews were conducted with 16 stakeholders involved. Hereby, the perspective of thalidomide-affected people (5) as well as the supporting makers (6) and experts (5) were taken into account. Through a subsequent structured analysis, various dimensions as well as relevant influencing factors could be identified.FindingsIn total, 33 paraphrases could be formed in 8 categories and four dimensions concerning the PDPs investigated. In addition, 17 paraphrases on potentials and challenges could be extracted through generalization.Originality/valueDue to findings' holistic approach, the findings form an empirical basis for further research into this still very young research topic and represent a first step toward theory building. By the applicability of the identified influencing factors an important contribution can be made to the supply of aids and the inclusion of people with disabilities.Peer reviewThe peer review history for this article is available at:https://publons.com/publon10.1108/JET-01-2022-0013
Forensic psychiatry in times of COVID-19: a qualitative study into the concerns and needs of patients
Authors: Simjouw Annabel , Verstegen Nienke , Smid Wineke , Langeveld Agnita 
Published: July 2022

Purpose
The aim of this study is to gain a better understanding of the concerns and needs of forensic psychiatric patients regarding the impact of the COVID-19 crisis on their mental health and treatment.

Design/methodology/approach
Semi-structured interviews were conducted with nine patients from various wards of the hospital. Using the consensual qualitative research method, these interviews were coded by a team of three researchers.

Findings
Four domains emerged from the analysis, namely, restrictions, emotional consequences, coping and communication. One of the primary restrictions for patients was not being allowed to have physical contact with the people in their network/visitors. This prompted patients, in some cases, to decline visitors altogether. Emotional consequences of the COVID-19 measurements included anxiety, frustration and passivity. Ambiguity about the rules added to this frustration. Furthermore, a cut in autonomy was felt by patients due to them not being able to do their own grocery shopping. Despite these restrictions that were imposed on patients, the relationship between patients and staff was perceived as good and even improved according to the participants.

Practical implications
A lack of autonomy emerged as a salient issue related to the restrictions within the hospital. Certain degrees of control may be inevitable, but it is nonetheless important to focus on the effect of control within forensic settings. This could be done by aiming to actively include patients in decisions that affect their living climate. Furthermore, it appeared that the “ballet dancer” approach was used by the staff of the hospital, leaving more room for individualized care. As perceived support is important to increase willingness to accept the treatment being offered, a focus on this approach in times of rapid change such as during a pandemic, would be recommended.

Originality/value
Because few pandemics have occurred in the past century, little information is available about how a pandemic might affect patients residing in forensic psychiatric hospitals. To the best of the authors’ knowledge this is one of the first studies to assess concerns and needs of forensic psychiatric patients regarding the COVID-19 pandemic.
Dividend reduction and stock price reaction in Indian market: is there a role of share repurchase?
Authors: Chatterjee Chanchal , Tiwari Sweta 
Published: July 2022

Purpose
This paper aims to analyze the stock price reaction because of dividend reduction (DR) announcements in the Indian equity market, controlling for share repurchases.

Design/methodology/approach
The sample comprises National Stock Exchange (NSE) 500 companies listed in the NSE Ltd. covering a time span from year 2009 to 2019. Using the event study methodology, the authors measure the impact of DR announcements on security prices around the event day. The authors also examine the price response to DRs at the interim stage versus the final stage and identify the factors that drive the decision to reduce dividends at the interim level versus final level.

Findings
The authors find that overall DR announcements negatively impact abnormal returns. Firms that experience stronger adverse price reaction following DR announcements resort to share repurchase in the same year to boost stock prices. The authors find that interim DRs create more negative price reactions than final DRs. Finally, firms experiencing lower levels of prior year earnings, firms with smaller sizes and overvalued firms tend to reduce dividends at the interim level instead of postponing the reduction to the final level.

Originality/value
This paper examines stock price reaction because of DR announcements of Indian firms. The sample comprises firms that reduce dividends with contemporaneous share repurchases as well as firms that reduce dividends without contemporaneous repurchase activity. To the best of the authors’ knowledge, studies on substitution effect of dividends with buyback in the context of Indian equity market are rare. Further, investigating the difference in stock price movement because of DRs at the interim level versus the final level is the unique contribution of this paper.
The olfactory experience (in retail) scale: construction, validation and generalization
Authors: Roy Subhadip , Singh Priyanka 
Published: July 2022

PurposeMeasurement scales for sensory experience in retailing exist for sight, touch and sound. In the present study, the authors aim to develop the olfactory experience (OEX) scale in the context of retailing.Design/methodology/approachBased on literature review and six studies that follow standard scale development protocols (combined n = 1,203), the authors develop and validate a three-dimensional OEX scale. The scale is further validated in the final study in a different market set-up than the first five.FindingsThe authors found the three dimensions of OEX as (scent) company, congeniality and congruity. The OEX scale is found to be generalizable and valid across different cultural and market set-ups. In addition, the OEX (i.e. the scale) was found to effect psychological and behavioral outcomes of the consumer in a significant manner.Research limitations/implicationsThe present study contributes to the domain of sensory experience in retailing with the OEX scale and provides three new dimensions of OEX for the academicians to further explore.Practical implicationsThe OEX scale provides a ready to use tool for the retailer to gauge the level of OEX in the store and to predict consumer attitudes and behavior.Originality/valueThe study is the first to develop a scale for OEX in retailing or for that matter in consumer behavior.
Optimal data backup policies for information systems subject to sudden failure

Published: July 2022

PurposeWith the irresistible growth in digitization, data backup policies become essential more than ever for organizations seeking to improve reliability and availability of organizations' information systems. However, since backup operations do not come free, there is a need for a data-informed policy to decide how often and which type of backups should be taken. In this paper, the authors present a comprehensive mathematical framework to explore the design space for backup policies and to optimize backup type and interval in a given system. In the authors' framework, three separate cost factors related to the backup process are identified: backup cost, recovery cost and data loss cost. The objective function has a multi-criteria structure leading to a backup policy minimizing a weighed function of these factors. To formalize the cost and objective functions, the authors get help from renewal theory in reliability modeling. The authors' optimization framework also formulates mixed policies involving both full and incremental backups. Through numerical examples, the authors show how the authors' optimization framework could facilitate cost-saving backup policies.Design/methodology/approachThe methodology starts with designing different backup policies based on system parameters. Each constructed policy is optimized in terms of backup period using renewal theory. After selecting the best back-up policy, the results are demonstrated through numerical studies.FindingsData backup polices that are tailored to system parameters can result in significant gains for IT (Information Technology) systems. Collecting the necessary parameters to design intelligent backup policies can also help managers understand managers' systems better. Designed policies not only provides the frequency of back up operations, but also the type of backups.Originality/valueThe original contribution of this study is the explicit construction and determination of the best backup policies for IT systems that are prone to failure. By applying renewal theory in reliability, the authors present a mathematical framework for the joint optimization of backup cost factors, i.e. backup cost, recovery time cost and data loss cost.

PurposeThe aims of this paper are to share how one cohort of tourism practitioners viewed the transformative change needed within the tourism industry and to explore the implications for leadership in the future.Design/methodology/approachThe research design is based on a virtual whiteboard brainstorming activity incorporating both the individual and collective thinking of 20 participants in a global cohort class. Using conversational techniques to elicit cognitive knowledge and felt experience, the methodology generates shared understandings about the opportunities and challenges of implementing regenerative tourism.FindingsThe conversations reported in the findings of this paper provide important insights into the challenges and opportunities faced by tourism professionals as enablers of regenerative tourism. Findings included, first, that participants within the course demonstrated characteristics of transformational leadership including a strong moral positioning, embodied self-awareness, collaboration and collective action. Second, specific points of inertia that impede regenerative tourism are identified including embedded culture, power and organisational structures. Third, professionals are calling for practical tools, new frames of reference, and examples to help communicate regenerative tourism.Research limitations/implicationsThis is a viewpoint, not a research paper. Nonetheless, it provides a rich vein of future research in terms of disruptive pedagogy, potentially gendered interest in regenerative tourism, issues of transforming the next generation and power.Practical implicationsGovernance, organisational, destination management strategies, planning and policy frameworks, individual issues as well as contradictions within the tourism system were revealed. Transformative change in an uncertain future requires transformational leadership, characterised by moral character and behaviours that trigger empowered responses.Originality/valueThis paper shares insights from a unique global cohort class of tourism professionals wherein the challenges and opportunities for regenerative tourism are identified. The methodology is unusual in that it incorporates both individual and collective thinking through which shared understandings emerge.
The advantages of using negotiated syllabus in EFL classes: exploring the undergraduate students' perceptions
Authors: Pakdaman Ali , Alibakhshi Goudarz , Baradaran Abdollah 
Published: July 2022

PurposeA couple of decades ago, the negotiated syllabus was introduced as an alternative to the predetermined syllabus. The review of the related studies shows the number of studies on the use of negotiated syllabus in English language teaching is scanty. The main purpose of the study was to explore the advantages/merits of employing negotiated syllabus in general English courses that undergraduate students take.Design/methodology/approachThe authors employed the phenomenology research method to deeply delve into the undergraduate students' perceptions of the advantages of the negotiated syllabus. The phenomenology method is used for investigating human lived experiences through the descriptions given by the people involved in the study. This qualitative research method is mainly used to study fields with little or no knowledge. The authors collected the data through in-depth interviews with the informants (18 students) who were selected through theoretical sampling. The informants were undergraduate students at Allameh Tabataba'i University who were selected through theoretical sampling. The authors listened to the recordings to transcribe the participants' statements and remarks verbatim. Then, we analyzed the interviews thematically through open, axial and selective coding. This study aimed at exploring the participants' perspectives on the advantages of the negotiated Syllabus. The study's main objective was to investigate the advantages/merits of employing negotiated Syllabus in undergraduate students' general English courses.FindingsFindings revealed that employing the negotiated syllabus resulted in many advantages which were reduced into three axial coding: psychological, pedagogical and individual. Generally, the negotiated syllabus reduces the students' anxiety, improves their motivation, affects their language achievement and develops their critical thinking and learner autonomy.Practical implicationsTeachers are recommended to minimize the constraints and use the negotiated syllabus to optimize language learners' motivation and language achievement in teaching English programs.Originality/valueThe impact of the negotiated syllabus on language learners has been investigated through quantitative research methods. However, the language learners' perceptions of the negotiated syllabus have not been well explored qualitatively.
Engineering Saccharomyces cerevisiae‐based biosensors for copper detection
Authors: Fan Cong , Zhang Danli , Mo Qiwen , Yuan Jifeng 
Published: July 2022

AbstractHeavy metals, that is Cu(II), are harmful to the environment. There is an increasing demand to develop inexpensive detection methods for heavy metals. Here, we developed a yeast biosensor with reduced‐noise and improved signal output for potential on‐site copper ion detection. The copper‐sensing circuit was achieved by employing a secondary genetic layer to control the galactose‐inducible (GAL) system in Saccharomyces cerevisiae. The reciprocal control of the Gal4 activator and Gal80 repressor under copper‐responsive promoters resulted in a low‐noise and sensitive yeast biosensor for copper ion detection. Furthermore, we developed a betaxanthin‐based colorimetric assay, as well as 2‐phenylethanol and styrene‐based olfactory outputs for the copper ion detection. Notably, our engineered yeast sensor confers a narrow range switch‐like behaviour, which can give a ‘yes/no’ response when coupled with a betaxanthin‐based visual phenotype. Taken together, we envision that the design principle established here might be applicable to develop other sensing systems for various chemical detections.
GATA transcription factor WC2 regulates the biosynthesis of astaxanthin in yeast Xanthophyllomyces dendrorhous

Published: July 2022

AbstractAstaxanthin is a type of carotenoid widely used as powerful antioxidant and colourant in aquaculture and the poultry industry. Production of astaxanthin by yeast Xanthophyllomyces dendrorhous has attracted increasing attention due to high cell density and low requirements of water and land compared to photoautotrophic algae. Currently, the regulatory mechanisms of astaxanthin synthesis in X. dendrorhous remain obscure. In this study, we obtained a yellow X. dendrorhous mutant by Atmospheric and Room Temperature Plasma (ARTP) mutagenesis and sequenced its genome. We then identified a putative GATA transcription factor, white collar 2 (XdWC2), from the comparative genome data and verified that disruption of the XdWC2 gene resulted in a similar carotenoid profile to that of the ARTP mutant. Furthermore, transcriptomic analysis and yeast one‐hybrid (Y1H) assay showed that XdWC2 regulated the expression of phytoene desaturase gene CrtI and astaxanthin synthase gene CrtS. The yeast two‐hybrid (Y2H) assay demonstrated that XdWC2 interacted with white collar 1 (XdWC1) forming a heterodimer WC complex (WCC) to regulate the expression of CrtI and CrtS. Increase of the transcriptional levels of XdWC2 or CrtS in the wild‐type strain did not largely modify the carotenoid profile, indicating translational and/or post‐translational regulations involved in the biosynthesis of astaxanthin. Overexpression of CrtI in both the wild‐type strain and the XdWC2‐disrupted strain apparently improved the production of monocyclic carotenoid 3‐hydroxy‐3′, 4′‐didehydro‐β, ψ‐carotene‐4‐one (HDCO) rather than β‐carotene and astaxanthin. The regulation of carotenoid biosynthesis by XdWC2 presented here provides the foundation for further understanding the global regulation of astaxanthin biosynthesis and guides the construction of astaxanthin over‐producing strains.
