AbstractTwo mutations occurred in SARS-CoV-2 early during the COVID-19 pandemic that have come to define circulating virus lineages1: first a change in the spike protein (D614G) that defines the B.1 lineage and second, a double substitution in the nucleocapsid protein (R203K, G204R) that defines the B.1.1 lineage, which has subsequently given rise to three Variants of Concern: Alpha, Gamma and Omicron. While the latter mutations appear unremarkable at the protein level, there are dramatic implications at the nucleotide level: the GGG→AAC substitution generates a new Transcription Regulatory Sequence (TRS) motif, driving SARS-CoV-2 to express a novel subgenomic mRNA (sgmRNA) encoding a truncated C-terminal portion of nucleocapsid (N.iORF3), which is an inhibitor of type I interferon production. We find that N.iORF3 also emerged independently within the Iota variant, and further show that additional TRS motifs have convergently evolved to express novel sgmRNAs; notably upstream of Spike within the nsp16 coding region of ORF1b, which is expressed during human infection. Our findings demonstrate that SARS-CoV-2 is undergoing evolutionary changes at the functional RNA level in addition to the amino acid level, reminiscent of eukaryotic evolution. Greater attention to this aspect in the assessment of emerging strains of SARS-CoV-2 is warranted.
Moderating impact of brand authenticity and control over ads on the effectiveness of Facebook advertising: a two-sample study
Authors: Sarfraz Usama , Bano Sobia 
Published: April 2022

PurposeThe aim of the present study is twofold. First is investigating the factors associated with the effectiveness of Facebook advertising and its resultant impact on behavioral and attitudinal loyalty. The second is testing the moderating impact of control over ads and brand authenticity.Design/methodology/approachThis study is conducted by adopting the cross-sectional data collection technique, two samples with 396 and 482 sample sizes were collected at different points in time. Partial least square-structural equation modeling (PLS-SEM) technique, using Smart PLS 3.0 software, was applied to analyze the data.FindingsThe results show that the moderating effect of behavioral control on the relationship between advertising intrusive and attitude towards Facebook advertising was insignificant for both samples. Brand authenticity was significant in moderating the relationship between an individual's attitude towards Facebook advertising and behavior towards the brand for sample 1 and was insignificant for sample 2. Behaving towards brands resulted in attitudinal and behavioral loyalty intentions of individuals for both samples.Originality/valueThis study contributes to the body of knowledge in four ways besides contextual contribution. First, it investigated the moderating influence of perceived behavioral control on the relationship between advertising intrusiveness and attitude towards Facebook advertising. Second, this study also studied the relationship between attitude towards Facebook advertising and behavior towards the brand, moderated by brand authenticity. Third, this study extended the Facebook advertising Framework to behavioral and attitudinal loyalty. Fourth, this study methodologically contributes by conducting a two-sample study to enhance the generalizability.
Signaling innovativeness in crowdfunding entrepreneurial narratives: the moderating roles of entrepreneurial passion and social endorsement
Authors: Lu Baozhou , Xu Tailai , Wang Ziqi 
Published: April 2022

PurposeThe purpose of this study is to investigate the effects of the innovativeness-related language of crowdfunding pitches on funding outcomes under different boundary conditions specified by two context-relevant signals, entrepreneurial passion and social endorsement.Design/methodology/approachThis study develops six hypotheses about the focal impacts of innovativeness-related language (i.e. incremental and radical) and the moderating effects of entrepreneurial passion and social endorsement. The hypotheses are tested with a sample of 1,057 real projects collected from a typical platform with a computer-aided content analysis method.FindingsThis study finds that pitches containing more incremental innovativeness language can generate more funds and that those containing more radical innovativeness language can lead to less favorable funding outcomes. While incremental innovativeness language interacts with entrepreneurial passion language to positively affect funding outcomes, radical innovativeness language requires social endorsement to diminish its negative effect on funding outcomes.Research limitations/implicationsThis study demonstrates that the content of messages of entrepreneurial narratives does indeed drive funding success in the context of reward-based crowdfunding and confirms the relevance of the consumer perspective of reward-based crowdfunding by using a real dataset.Originality/valueThis work joins a number of entrepreneurial narrative studies investigating the impacts of the innovativeness-related language of pitches (issue-relevant content) and their interactions with informational signals (i.e. entrepreneurial passion and social endorsement) on funding outcomes in the context of reward-based crowdfunding.
Research on constant force grinding control of aero-engine blades based on extended state observer
Authors: Dai Shijie , Zhang Wenhua , Ji Wenbin , Zhao Yufeng , Zheng Hongwei , Mu Jiaheng , Li Pengwei , Deng Riqing 
Published: April 2022

Purpose
Considering the influence of environmental noise and modeling error during the process of the robotic automatic grinding aero-engine blade, this study aims to propose a method based on the extended state observer (ESO) to reduce the fluctuation of normal grinding force.

Design/methodology/approach
First, the measurement range of the six-dimensional force sensor is calibrated according to the maximum acceleration of end-effector and grinding force. Second, the gravity and zero drift compensation model is built to compensate for measurement error. Finally, the switching function is designed based on the difference between the expected grinding force and the actual feedback value. When the value of function stays within the switching band, a nonlinear active disturbance rejection control (ADRC) loop is applied. When the function value reaches outside the switching band, an ESO-based sliding mode control (SMC) loop is applied.

Findings
The simulated and experimental results show that the proposed control method has higher robustness compared with proportion-integral-derivative (PID), Fuzzy PID and ADRC.

Research limitations/implications
The processing parameters of this paper are obtained based on the single-factor experiment without considering the correlation between these variables. A new control strategy is proposed, which is not only used to control the grinding force of blades but also promotes the development of industrial control.

Originality/value
ESO is used to observe environmental interference and modeling errors of the system for real-time compensation. The segment control method consisting of ESO-based SMC and ESO-based ADRC is designed to improve the robustness. The common application of the two parts realizes suppression of fluctuation of grinding force.

Procedural justice and affective commitment are crucial aspects of an organization. Limited research has been conducted linking procedural justice, organizational trust, job satisfaction and affective commitment. This study was conducted in the South Asian country of India, where power-distance prevails
Platform ecosystem development in an institutionalized business market: the case of the asset management industry
Authors: Hendricks Leeya , Matthyssens Paul 
Published: April 2022

Purpose
This study aims to investigate the impact of an institutionalized market context on platform ecosystem development. It studies how platform ecosystems are set up and evolve in the asset management industry and explores the role of the platform leader and selected core network partners in unleashing value innovation notwithstanding institutional barriers. A problematization lens is used to identify deviations between the management practices in this industry setting and the prescriptions and suggested practices in the extant literature on platform ecosystem development.

Design/methodology/approach
The research follows a retrospective longitudinal single-case design focusing on the development of a new platform ecosystem to which several PaaS initiatives are linked. It is based on 13 in-depth interviews over a one-year period triangulated with documentation and member checks. This study identifies the impact of regulations and norms on the early stages of platform ecosystem development.

Findings
In this institutionalized market, intensified interactions between carefully selected strategic market players focusing on platform development, lead to growing value innovation initiatives. The collaboration between core actors evolves “under the radar” with select partners and with lots of controls by incumbents. The value innovation process evolves in a non-disruptive way. Initially, the new value initiatives are rather incremental and focus on optimizing the present business models while slowly adding new peripheral services shared as successful signs of value innovation initiatives. This “submerged” direction enables platform actors to gather critical mass and stimulates co-evolution with key players.

Research limitations/implications
This paper outlines one vertical and looks at various principles involved during early stages of platform development. Because the authors have chosen a deep dive into one institutionalized setting, future studies could investigate a broader scope of institutionalized settings/verticals and a broader scope of management stages and related practices to replicate the study and corroborate the findings. The idea raised from hybrid platform ecosystem development also warrants further study.

Practical implications
Practitioners in institutionalized business-to-business markets find suggestions on how to overcome institutional barriers to platform ecosystem development and this study shows which levers can be used by core actors of ecosystems to strengthen established business models and simultaneously unleash value innovation initiatives.

Originality/value
This study contributes to the understanding of the challenges to be faced when setting up and expanding platform ecosystems in a highly institutionalized setting and identifies “levers” to create a smooth flow and snowball effect for platform ecosystem development. It “fine-tunes” the extant literature on platform ecosystem development to institutionalized markets.

Theorising brand aura
Authors: Alexander Nicholas , Doherty Anne Marie 
Published: April 2022

PurposeBuilding on Walter Benjamin's philosophical reflections on aura and authenticity, this article aims to conceptualise and theorise brand aura.Design/methodology/approachThis article extends understanding of brand aura within the management, marketing and tourism literature with reference to Benjamin's framing of aura and authenticity in time and space.FindingsWithin a Benjaminian framework this article theorises brand aura and offers a conceptualisation of the antecedents of brand aura. It explores the duality of what is termed here as artefactual authenticity and existential authenticity. It illustrates the central role of consumers' mémoire involontaire in the realisation of brand aura. Within this Benjaminian framework, the article explores how artefactual authenticity is preceded by brand essence, while existential authenticity precedes brand essence. Implications for the management of the service encounter are discussed with reference to territorial legitimacy and historical testimony in the context of the firm's role in supporting consumer experiential engagement.Originality/valueThis article advances theoretical understanding of how consumers engage experientially with brand aura and how firms curate brand aura.
Impact on community members of a culturally appropriate adaptation of a social and emotional well-being intervention in an aboriginal community
Authors: Anwar-McHenry Julia , Murray Lesley , Drane Catherine F. , Owen Julie , Nicholas Amberlee , Donovan Robert J. 
Published: April 2022

Purpose
Indigenous Australians report mental health problems at a much higher rate than non-Indigenous Australians. However, rather than more services, it has been proposed that there should be a positive, socially based approach to improving mental health in Indigenous communities. The population-wide Western Australian Act-Belong-Commit mental health promotion campaign appeared to be consistent with such an approach. Hence, after consultation with Indigenous community members, a culturally adapted version of the campaign was developed and launched in a largely Indigenous remote Australian community. A survey of Indigenous community members was conducted two years later to assess campaign impact. The aim of this paper is to report on the impact on community members of this cultural adaptation.

Design/methodology/approach
Intercept interviews were conducted with Indigenous community members (n = 31) to assess respondents’ awareness of the campaign elements and activities, understanding of campaign messages and whether respondents had undertaken activities to improve their own or their family’s social and emotional well-being as a result of the campaign.

Findings
There was universal awareness of the adapted campaign in this sample, with 81% reporting doing something for their own social and emotional well-being, 74% reporting doing something for the social and emotional well-being of their family or friends and 48% reporting doing something for community well-being, as a result of campaign exposure.

Originality/value
The cultural adaptation of the Act-Belong-Commit campaign in the Australian Roebourne community is the first reported Indigenous adaptation of a population-wide mental health promotion campaign.
Creating harmony through a plethora of interests, resources and actors: the challenging task of orchestrating the service ecosystem
Authors: Carida' Angela , Colurcio Maria , Edvardsson Bo , Pastore Alberto 
Published: April 2022

PurposeThere is a need to understand value co-creation in service ecosystems that engage multiple actors with different goals. This study aims to extend the understanding of value co-creation by considering the orchestration of service ecosystems with reference to resource-integration processes.Design/methodology/approachAn exploratory case study approach is used to analyze actors' roles in resource orchestration within a service ecosystem, gathering data from the macro, meso and micro levels of an Italian hospitality and tourism services ecosystem.FindingsA framework is devised that highlights the intersection between orchestration and resource integration for value co-creation processes across the macro, meso and micro levels in service ecosystems. This extends the understanding of service ecosystem dynamics, especially how new value co-creation structures emerge, by emphasizing the circular causality between system levels. Findings show how orchestrating resource integration activities initiate and institutionalize non-linear value co-creation processes.Practical implicationsResource integration orchestration within and between ecosystem levels is a possible response to societal challenges and for creating economic, cultural and social value across the community. The study offers policymakers insights into developing new competencies for developing actions according to a logic of socially and sustainable value.Originality/valueThis study advances the understanding of service orchestration by expanding the concept and the feasibility of service ecosystem orchestration. It offers insights into the importance of orchestrating resource integration to the emergence and vitality of service ecosystems themselves. The study responds to the need for empirical studies on value co-creation.
Research on policy diffusion mechanism of Government Procurement of Public Services based on an MFCM
Authors: Zhang Yuting , Xu Lan , Lu Zhengnan 
Published: April 2022

PurposeThe purpose of this paper is to show that research on policy diffusion mechanism of Government Procurement of Public Services (GPPS) is beneficial to improve the efficiency of policy formulation and implementation.Design/methodology/approachIn view of the four dimensions which are internal demand, external pressure, policy innovation environment and service characteristic, a system of factors affecting policy diffusion is established. On this basis, a Multilayer Fuzzy Cognitive Map (MFCM) model for policy diffusion of GPPS is constructed. Nonlinear Hebbian Learning algorithm and genetic algorithm are applied to optimize the two components of the MFCM model, which are relationship between nodes at the same layer and influence weights between nodes at different layers, respectively. Taking Nanjing municipal government purchasing elderly-care services in China as the empirical object, simulation of policy diffusion based on the MFCM model is carried out, aiming to obtain the key factors influencing policy diffusion and the dynamic diffusion mechanism of GPPS policy.FindingsResearch results show that, compared with monolayer Fuzzy Cognitive Map, the MFCM model converges faster. In addition, simulation results of policy diffusion indicate that economic development level of jurisdiction, superior pressure, administrative level and operability of services are key influencing factors which are under four dimensions correspondingly. And the dynamic influencing mechanism of key factors has also been learned.Originality/valueThis paper constructs the MFCM model, which is a new approach based on several monolayer FCMs, to study the policy diffusion mechanism.
