A SARS-CoV-2 mini-genome assay based on negative-sense RNA to study replication inhibitors and emerging mutations
Authors: Vial Thomas , Oade Michael S. , Russell Colin A. , Eggink Dirk , te Velthuis Aartjan J.W. 
Published: June 2021

AbstractSevere Acute Respiratory Coronavirus 2 (SARS-CoV-2) is a positive-sense single-stranded RNA virus and the causative agent of the Coronavirus disease 2019 (COVID-19) pandemic. Efforts to identify inhibitors of SARS-CoV-2 replication enzymes and better understand the mechanisms underlying viral RNA synthesis have largely relied on biosafety level 3 (BSL3) laboratories, limiting throughput and accessibility. Recently, replicon systems have been proposed that involve~30 kb RNA-based replicons or large plasmids that express the viral structural and non-structural proteins (nsp) in addition to a positive-sense reporter RNA. Unfortunately, these assays are not user-friendly due to plasmid instability or a poor signal to background ratio. We here present a simple mini-genome assay consisting of a~2.5 kb-long negative-sense, nanoluciferase-encoding sub-genomic reporter RNA that is expressed from a plasmid, and amplified and transcribed by the SARS-CoV-2 RNA polymerase core proteins nsp7, nsp8 and nsp12. We show that expression of nsp7, 8 and 12 is sufficient to obtain robust positive- and negative-sense RNA synthesis in cell culture, that addition of other nsps modulates expression levels, and that replication of the reporter RNA can be inhibited by active site mutations in nsp12 or the SARS-CoV-2 replication inhibitor remdesivir. The mini-genome assay provides a signal that is 170-fold above background on average, providing excellent sensitivity for high-throughput screens, while the use of small plasmids facilitates site-directed mutagenesis for fundamental analyses of SARS-CoV-2 RNA synthesis.Importance statementThe impact of the COVID-19 pandemic has made it essential to better understand the basic biology of SARS-CoV-2, and to search for compounds that can block the activity of key SARS-CoV-2 replication enzymes. However, studies with live SARS-CoV-2 require biosafety level 3 facilities, while existing replicon systems depend on long positive-sense subgenomes that are often difficult to manipulate or produce a high background signal, limiting drug-screens and a rapid analysis of emerging SARS-CoV-2 mutations during the COVID-19 pandemic. To make it easier to study emerging SARS-CoV-2 mutants and screen for inhibitors, we developed a simple mini-replicon that produces a minimal background signal, that can be used in any tissue culture lab, and that only requires four small plasmids to work.
A dual process on shopping well-being across shopping contexts: the role of shopping values and impulse buying
Authors: Nghia Ho Trong , Olsen Svein Ottar , Trang Nguyen Thi Mai 
Published: June 2021

PurposeAdopting the duality approach, this study aims to examine cognitive and affective associations between shopping values, impulse buying tendencies and consumer shopping well-being. In addition, the study also aims to test the moderating role of self-control and compare the proposed relationships across the offline and online shopping contexts.Design/methodology/approachA survey dataset was collected from a sample of 529 offline and online consumers in Vietnam. Structural equation modelling (SEM) was employed to test the proposed relationships among the studied constructs.FindingsThe consequence of impulse buying is positive and affect-based. In addition, the positive associations between shopping values and impulse buying via dual process are validated and moderated by self-control. In addition, the association between cognitive impulse buying and shopping well-being is stronger in the online shopping context, whereas hedonic value has more influence on affective impulse buying in the offline shopping context. All other relationships are not statistically different across the two shopping contexts.Originality/valueThis study introduces an appropriate theoretical framework for studying impulse buying—the duality approach. Second, the research validates the dual process and positive consequence of impulse buying. Third, self-control's moderating role is validated, whereas the studied associations are initially compared across shopping contexts.

Authors: Gong Zheng , Wang Nannan 
Published: June 2021

Purpose
Innovation has been acknowledged as the key for modern industries. However, the construction industry is criticised for being poor in innovation performance compared to other industry sectors. Large construction firms are the main contributor to technological innovation in the construction industry, but the driving process of their technological innovation has not yet been fully investigated in previous studies. The purpose of this paper is to provide quantitative analysis of the technological innovation driving process of large construction firms.

Design/methodology/approach
An extended crépon, duguet and mairesse (CDM) model has been developed to analyse the key influencing factors for technological innovation in construction firms. The sample data are selected from the world’s largest construction market, China, and include 129 listed construction firms.

Findings
The results show significant positive correlation between R&D investment and innovation output and also between innovation output and performance. The effect of influencing factors on the R&D investment, innovation output and performance are also revealed by the empirical study. The underlying reasons are discussed and suggestions are given for the construction industry to improve the technological innovation capacity of construction firms.

Originality/value
This research contributes to the literature of construction innovation and benefits practitioners by providing a quantitative approach to demonstrate the driving process of innovation in construction firms.

Published: June 2021

PurposeThe present study investigates the moderating role of customer trust in customer relationship management (CRM) components and customer loyalty relationships in the context of the baking sector in Bangladesh.Design/methodology/approachData were collected through a survey using a structured questionnaire from 350 customers of commercial banks in Bangladesh.FindingsThe key finding is that all CRM components (customer orientation, customer advocacy and customer knowledge) except customer engagement have positive impact on customer loyalty. Moreover, customer trust only moderates the relationship between customer knowledge and customer loyalty, whereas other CRM components and customer loyalty do not moderate by trust.Originality/valueThe findings of the study add to the substantial pool of knowledge on CRM components, customer trust and customer loyalty literature. More specifically, the moderating role of customer trust between customer knowledge and customer loyalty is the novel contribution of this research which will enrich the existing CRM literature particularly in the banking sector of Bangladesh.
Investor confidence and life insurance demand: can economic condition limit life insurance business?
Authors: Ahmed Danish , Xie Yuantao , Issam Khelfaoui 
Published: June 2021

PurposeLife insurance is bought with a prior belief that promise stipulated in policy will be honored when due. Discernibly, this belief is backed by the confidence that financial markets and economy will demonstrate satisfactory performance. However, individuals' confidence levels may get shaken through naïve reinforcement learning if they witness negative market or economic condition. Considering this the authors investigate the relationship between investor confidence and life insurance demand.Design/methodology/approachThe authors used bias corrected bootstrapped sample of OECD economies to examine the link between investor confidence and life insurance demand when two possible economic conditions were witnessed: 1) normal/economic expansion and 2) economic/debt impairment. The findings are robust to alternate estimation techniques and endogeneity.FindingsThe authors found that lower investor confidence, sovereign debt impairment and negative market condition will have negative repercussion on life insurance demand. On the other hand, investor confidence-life insurance demand nexus is merely influenced by market and economic condition.Originality/valueThis is a premier research explaining the nexus between investor confidence and life insurance demand in the context of life-cycle hypothesis, sovereign ratings channel and experience-confidence-belief framework. The finding will help economic policy-makers in developing pre-emptive measures to protect life insurance businesses from negative repercussions of lower confidence and negative market conditions.
Risk allocation, transfer and management in public–private partnership and private finance initiatives: a systematic literature review
Authors: Tallaki Mouhcine , Bracci Enrico 
Published: June 2021

PurposeThis paper examines risk and risk management in public–private partnership and private finance initiatives (PPP/PFI). Despite growing interest in PPP/PFI, there are knowledge gaps in the literature. The authors’ aim is to analyse these knowledge gaps and define emerging themes to guide future research agendas.Design/methodology/approachThe authors conduct a systematic literature review from 1990 to 2018 using the Scopus database.FindingsThe authors define six emerging themes: risk definition and types of risks; value for money (VFM) and risk; risk sharing, allocation and transfer; financial risk; contractualisation and renegotiation of risk; and risk management and governance. They proposed a conceptualisation of potential development of PPP/PFI research through the three phases of risk management cycle, i.e. prospective, real time and retrospective. This paper revealed some new aspects that could help to analyse better risk and risk management in PPP/PFI to reach value for money (VFM) and to exploit the potential of PPP/PFI.Originality/valueDespite the increasing attention to PPP/PFI, further researches are required in relation to operational and post-operational risk studies, risk management and control, the role of trust. The authors’ analysis underlines the difficulties in how risk is perceived and how to ascertain VFM. In addition, the authors highlight how the increase of contract renegotiation is changing the provisions with reference to risk assignment creating market distortion. Risk should be managed as a cycle; PPP/PFI would benefit by engaging more with the risk management literature.

Authors: Vadalkar Suniti , Chavan Gitesh , Chaudhuri Ranjan , Vrontis Demetris 
Published: June 2021

PurposeAmidst the plethora of mass communication methods that technology bestowed business with, print advertisements still remain an effective and widely utilized advertising tool, and retain a diachronically venerable position in international marketing practice. Bar and transcending mere academic fascination or curiosity, this research provides insights into the past, an understanding of the present and an outlook into the future. In this vein, through a methodical and comprehensive critical review of extant literature on print advertisements since 1965, this research aims to identify gaps in extant knowledge, to map its trends and divergences, to trace its paradigm shifts and to ultimately develop agendas for truly significant future research.Design/methodology/approachThis spatial-temporal study reviews 256 methodically selected articles, using VantagePoint software, and adopts a novel methodology through natural language processing (NLP), text mining, auto-correlation maps, and bubble maps to conduct and present a robust analysis and explicit findings.FindingsUsing also the VOSviewer for density and network visualization, the results identify the predominant literature themes and, conversely, the relatively under-researched areas, and provide a more insightful collective interpretation of extant works, while laying the foundation for future research of greater value and significance to academia and industry.Originality/valueThis study transcends the partial and/or limited analyses and perspectives of extant literature to present scholars with the first comprehensive and long term meta-analysis or systematic study of print advertising, with explicit findings of both scholarly and executive worth.
Cyclicity of real estate-related trends: topic modelling and sentiment analysis on German real estate news
Authors: Ploessl Franziska , Just Tobias , Wehrheim Lino 
Published: June 2021

PurposeThe purpose of this paper is to identify and analyse the news coverage and sentiment of real estate-related trends in Germany. Trends are considered as being stable and long-term. If the news coverage and sentiment of trends underlie cyclicity, this could impact investors’ behaviour. For instance, in the case of increased reporting on sustainability issues, investors may be inclined to invest more in sustainable buildings, assuming that this is of growing importance to their clients. Hence, investors could expect higher returns when a trend topic goes viral.Design/methodology/approachWith the help of topic modelling, incorporating seed words partially generated via word embeddings, almost 170,000 newspaper articles published between 1999 and 2019 by a major German real estate news provider are analysed and assigned to real estate-related trends. Through applying a dictionary-based approach, this dataset is then analysed based on whether the tone of the news coverage of a specific trend is subject to change.FindingsThe articles concerning urbanisation and globalisation account for the largest shares of reporting. However, the shares are subject to change over time, both in terms of news coverage and sentiment. In particular, the topic of sustainability illustrates a clearly increasing trend with cyclical movements throughout the examined period. Overall, the digitalisation trend has a highly positive connotation within the analysed articles, while regulation displays the most negative sentiment.Originality/valueTo the best of the authors’ knowledge, this is the first application to explore German real estate newspaper articles regarding the methodologies of word representation and seeded topic modelling. The integration of topic modelling into real estate analysis provides a means through which to extract information in a standardised and replicable way. The methodology can be applied to several further fields like analysing market reports, company statements or social media comments on real estate topics. Finally, this is also the first study to measure the cyclicity of real estate-related trends by means of textual analysis.
Conscious capitalism and the organizational propensity to fight corruption
Authors: Dion Michel 
Published: June 2021

Purpose
The purpose of this paper is to examine how much the basic tenets of conscious capitalism could favor organizational change and anticorruption strategies.

Design/methodology/approach
The paper questions the vagueness of the tenets and principles of conscious capitalism. It unveils the idealized worldview of conscious capitalism, as it is based on a “pseudo-humanistic and pseudo-holistic” philosophy. The paper analyzes various kinds of rationale for justifying anticorruption measures and explains how the conscious capitalism movement should assume the challenge to develop one or the other rationale.

Findings
The conscious capitalism movement does not have basic rationale for any self-justified discourse about anticorruption measures. The principles of conscious capitalism organizations can be coherent with a rationale of individual and organizational compliance. They could be suitable with a rationale of legal, industry and international compliance. We could expect that the principles of conscious capitalism allow radical changes in the organizational culture. However, the main principles of conscious capitalism are not explicitly related to any rationale for a corporate self-justified discourse about anticorruption measures.

Research limitations/implications
The three kinds of rationale for corporate self-justified discourse about anticorruption measures are not exhaustive. There can be other kinds of corporate rationale. Moreover, the conscious capitalism movement appeared in 2000s and is still evolving. So, we should never take for granted that the present ideals and principles of conscious capitalism will never be improved and deepened.

Originality/value
The paper explains how the conscious capitalism movement remains unable to present its rationale for justifying anticorruption measures. In doing so, it provides three kinds of rationale that conscious capitalism organizations could use to develop their corporate self-justified discourse about anticorruption policies, measures and programs.
One size fits all? Segmenting consumers to predict sustainable fashion behavior
Authors: Haines Shelley , Lee Seung Hwan (Mark) 
Published: June 2021

PurposeThis study segmented consumers by combining emotional and shopping characteristics to develop typologies that classify their consumption patterns and disposal behaviors.Design/methodology/approachTo identify segments of fashion consumers, an online questionnaire was administered measuring emotional and shopping characteristics, including perspective taking, empathic concern, personal distress, hedonism, and frugality. An online questionnaire involving 168 US-based participants were used to accomplish the purpose of the study. A cluster analysis was conducted to identify segments of participants based on these variables. Consumption patterns and disposal behavior, including motivation to buy environmentally friendly items, consciousness for sustainable consumption, buying impulsiveness, likelihood to follow fashion trends, and tendencies to dispose of or repair damaged or unwanted items were also measured via the questionnaire as dependent variables to be predicted by identified segments.FindingsThree clusters of consumers were identified as: Distressed and Self-Oriented, Warm and Thrifty, and Cold and Frivolous. Distressed and Self-Oriented individuals reported the highest levels of personal distress and hedonism. Warm and Thrifty individuals reported the highest levels of empathic concern, perspective taking and frugality, and the lowest levels of personal distress and hedonism. Cold and Frivolous individuals reported the lowest levels of perspective taking, empathic concern, and frugality.Originality/valueThe classification of consumers into segments brings a new dimension to the field of sustainable fashion. Clusters were created according to the variables of emotional characteristics (i.e. perspective taking, empathic concern, and personal distress) and shopping characteristics (i.e. hedonism and frugality). The analysis unveiled three distinct clusters that can be utilized to develop tailored strategies to successfully promote sustainable fashion consumption.
Examining the influences of perceived exclusivity and perceived rarity on consumers' perception of luxury
Authors: Wang Xujia , Sung Billy , Phau Ian 
Published: June 2021

PurposeThe purpose of this study is to investigate how exclusivity and rarity (natural versus virtual) influence consumers' perceptions of luxury. Further, it examines whether exclusivity and rarity can function as distinct marketing strategies in today's luxury market environment.Design/methodology/approachOnline questionnaires were administered by adapting developed scales from prior research. Research stimuli were chosen from three luxury categories including bags, wine and cruise. Confirmatory factor analysis and multiple regressions were used to test the hypotheses.FindingsThe results confirmed that exclusivity, natural rarity and virtual rarity were perceived as relatively distinct constructs among our sample. Findings also highlighted that perceived natural rarity (PNR) has consistently emerged as a positive and significant contributor to consumers' perceptions of luxury across all three luxury categories. The influence of perceived exclusivity (PE) on perceptions of luxury has also shown to be significant for two product categories (luxury bag and luxury wine), whereas perceived virtual rarity (PVR) did not show any significant effects across all three categories.Practical implicationsThe results indicate that consumers perceive natural rarity, virtual rarity and exclusivity as relatively distinctive marketing strategies. This suggests that luxury businesses can adopt each strategy independently to achieve desired marketing outcomes.Originality/valueThis study offers theoretical support for the proposition that exclusivity and rarity may have different functions in luxury marketing implementations. It provides empirical evidence showing the distinctiveness of perceived exclusivity and perceived rarity, which have not be done in previous research.
Mediating role of place identity in the relationship between place quality and user satisfaction in waterfronts: a case study of Penang, Malaysia
Authors: Isa Mohd Ismail , Hedayati Marzbali Massoomeh , Saad Siti Nursyahira 
Published: June 2021

Purpose
One major challenge for urban planners and policymakers is how to strengthen and establish connections between humans and the environment. Evidence suggests that the physical characteristics of the environment enhance both place identity and user satisfaction. This study aims to investigate the mediating role of place identity in the relationship between place quality and user satisfaction in two waterfronts in Penang, Malaysia. However, only few studies have examined the impact of place quality on user satisfaction in waterfronts as natural outdoor recreation spaces.

Design/methodology/approach
A sample of 300 users was analysed via structural equation modelling, and results show that place quality is a second-order construct with three main dimensions.

Findings
These results support the theoretical findings in the literature that associate high place quality and place identity with user satisfaction. These results also support the mediating role of place identity in the relationship between place quality and satisfaction and can help policymakers create inclusive and attractive waterfronts that catalyse place identity and user satisfaction.

Originality/value
Place quality is an essential need for urban life with significant and extensive effects on the lives of residents nowadays. Organising physical activities can help attract more users to waterfronts and consequently increase their level of satisfaction. Local authorities, non-governmental organisations and local communities should also help in monitoring and maintaining the waterfronts.
