Purpose
This paper aims to examine the change of institutional logics in actors' practices within crowdfunding platforms, seen as open collaborative ecosystems.


Design/methodology/approach
The research follows an abductive approach, wherein data collection and analysis, and the search for complementary theories, constitute parallel iterative processes. A main case study was carried out, complemented by an expert panel.


Findings
Balanced centricity (BC) as the main institutional logic in crowdfunding platforms delineates actors' practices (aims, resources and behaviors) into four issues: the development of an open and collaborative community; the overcoming of resource limitations; the changing roles of actors; and the co-creation of mutual (societal) value.


Research limitations/implications
This study context limits the results. The COVID-19 crisis put all actors in the medical field into an extreme situation in which they had to maximize their potential to achieve a common aim. Once the crisis has passed, further research should address whether BC is maintained as actors' institutional logic.


Originality/value
This paper offers a unique perspective on BC as an institutional logic that impacts actors in collaborative open ecosystems.

Purpose
Over recent years, few industries have seen such dramatic changes as the healthcare industry. The potential connectivity of digital technologies is completely transforming the healthcare ecosystem. This has resulted in companies increasingly investing in digital transformations to exploit data across channels, operations and patient outreach, by building on a practice approach and actor-network theory and being informed by service-dominant logic, this study aims to contribute by advancing the agential role of third-party actors to prompt innovation and shape service ecosystems.


Design/methodology/approach
This research is grounded in an epistemological contextualism. To gain situated knowledge and address the role of context in knowledge, understanding and meaning the authors adopted a qualitative methodology to study actors in their different contexts. The empirical research was based on case theory. The authors also took guidance from practice scholars about how to investigate actors' practices. The unit of analysis moves from dyadic relationships to focus on practices across different networks of actors.


Findings
This study expands on the conceptualization of triad as proposed by Siltaloppi and Vargo (2017) by moving from the form of triadic relationships – brokerage, mediation and coalition – to the agency of e-health third-parties; and their practices to innovate in the healthcare ecosystem. This study focuses on the actors and the performativity of actions and grounding the conceptual view on an empirical base.


Practical implications
Third-party actors bring about innovative ways of doing business in the healthcare ecosystem. Their actions challenge the status quo and run counter to long-time practices. Third-parties support the complex set of interconnections between different healthcare actors for the provision of new service co-creation opportunities. Considering how these e-health third-parties performs has implications for health managers, patients and other actors.


Originality/value
This study focuses on the actors and the performativity of actions and grounding the conceptual view on an empirical base. The agency of third-party actors is their ability to act among others and to connect multiple social and material structures to boost innovation. They prompt innovation and shape service ecosystems by brokering, mediating and coalescing among a great variety of resources, practices and institutions.

Purpose
Prior research acknowledges the lack of theorizing of markets within marketing. This paper aims to capture the emerging themes linked to different conceptualizations of the market and provide a language system for theorizing the market.


Design/methodology/approach
The paper conducts a bibliometric analysis of 177 articles and 22 keywords and adopts Mele et al.'s (2015) market conceptualization to interpret the results.


Findings
The bibliometric analysis detects five thematic clusters: market driving, market exchange, market shaping, market practices and macro-marketing. Based on their degrees of relevance and development, these are arranged into two groups. The analysis of these two language systems shows a shift toward a more comprehensive conversation on how the market is conceptualized. The authors synthesize this shift under the expression "from market driving to market shaping."


Research limitations/implications
The comparison of the two language systems allows the argument that market is a complex concept and that to understand it necessitates a rich set of terms.


Practical implications
The different ways of conceptualizing the market mean that managers face a choice when analyzing their market situations (what language system to use). This choice will be consequential for their subsequent actions.


Originality/value
This paper contributes to the identification of two rival language systems and narratives: market driving and market shaping.

This article advances a conceptualization of service innovation as socially constructed through resource integration and sensemaking. By developing this view, the current study goes beyond an outcome perspective, to include the collective nature of service innovation and the role of the social context in affecting the service innovation process. Actors enact and perform service innovation through two approaches, one that is more concerted and another that emerges in some way. Each approach is characterized by distinct resource integration processes, in which the boundary objects (artifacts, discourses, and places) play specific roles. They act as bridge-makers that connect actors, thereby fostering resource integration and shared meanings.

Purpose
This paper aims to focus on how the use of new technologies disrupts markets. To date, marketing literature has lacked studies investigating the link between market practices and new technologies. The study adopts the blockchain technology (BcT) context to elicit novel technology-enhanced market practices.


Design/methodology/approach
The authors adopt a qualitative multimethod research design to engage in interpretative theorizing. They investigated 77 companies and used the Gioia method for the data coding and analysis.


Findings
The study of the adoption of blockchain prompts three technology-enhanced market practices. The latter offers new ways of resourcing by removing constraints and expanding actors' network and knowledge to integrate resources; sensemaking by expressing new language and assigning novel meaning to represent markets; and legitimizing, by structuring new rules and trusting new mechanisms to institutionalize markets.


Research limitations/implications
The technology-enhanced market practices are distinct from extant market practices as well as related, thus, enriching and complementing them. Therefore, this work expands the understanding of the mechanisms of how markets work.


Originality/value
This study is the first, to the best of the authors' knowledge, to focus on how BcT features affect market practices. BcT market practices entail how actors perform, share and interpret symbols and objects and set rules for how markets should work.

Purpose
COVID-19 has dramatically changed how people live, socialise and think about their future. The disruptive shock that hit societies all over the world had a significantly negative impact on businesses, creating not only economic discontinuity but also uncertainty and disorientation. This special issue on COVID-19 aims to phrase the pandemic crisis and its impact on how to do business.


Design/methodology/approach
The authors follow MacInnis's (2011) suggestion that a conceptual article sees what others have identified in a new or revised way.


Findings
The authors develop the crisis management framework. The authors acknowledge that disruptive events may be repeated, and their consequences will have long-term and permanent impacts. These aspects highlight the need for a systemic approach in which the focus is not limited to an analysis of the cause of the crisis and ways of solving it but includes the paths through which the business, economic and social systems evolve because of the crisis.


Practical implications
Managerial policies, business models and practices that have been effective up to now will probably no longer work. Beyond this backdrop, the articles compiled in this special issue aim to help set the agenda for post-COVID business research


Originality/value
The authors identify four primary themes captured by these articles: strategies, capabilities, organisational transformations and value processes. In their entirety, they represent pieces of a conceptual puzzle that do not provide knowledge of "hard facts" but rather a "soft interpretation of how to approach the "new normal", i.e. a new social and business context.

Purpose
The COVID-19 wave spread all over the global market, affecting all industries. This paper aims to develop the understanding of how service systems can enhance their viability when facing rapid systemic changes.


Design/methodology/approach
The authors use data from Reddit, and particularly the subreddit r/coronavirus, to identify posts that discuss the impact of coronavirus on business. The authors use an algorithm to scrape the data with business-related search terms and elaborate relevant posts.


Findings
The findings show key topics and related sentiments on the impact of COVID-19 on business. Service systems can enhance viability by identifying alternative paths for emerging opportunities (by being creative), seize opportunities offered by the changing environment (by being opportunistic), not compromise conditions for internal balance (by being resilient), focus attention on critical purposes (by being essential) and perform nonharmful actions (by being responsible).


Originality/value
This paper proposes a framework depicting five possible key enhancers of viability to face a systemic crisis. In brief, companies need to ensure that they are creative, opportunistic, resilient, essential and responsible.

Background: Titanium dioxide (TiO(2)) is used as a food additive in pastries, sweets, and sauces. It is recognized as safe by food safety authorities, but in recent years, governments and scientists have raised concerns about its genotoxicity. This systematic review aims to assess the potential associations between food TiO(2) exposure and microbiota composition and functions. Methods: A systematic literature search was performed up to December 2020 in PubMed, Web of Science, and Scopus databases. The PRISMA guidelines followed. The risk of bias was assessed from ARRIVE and SYRCLE tools. Results: A total of 18 animal studies were included (n = 10 mice, n = 5 rats, n = 2 fruit flies, n = 1 silkworm). Studies varied significantly in protocols and outcomes assessment. TiO(2) exposure might cause variations in abundance in specific bacterial species and lead to gut dysfunctions such as a reduction in SCFAs levels, goblet cells and crypts, mucus production, and increased biomarkers of intestinal inflammation. Conclusions: Although the extrapolation of these results from animals to humans remains difficult, this review highlights the key role of gut microbiota in gut nanotoxicology and stimulates discussions on the safe TiO(2) use in food and dietary supplements. This systematic review was registered at PROSPERO as CRD42020223968.

Several researchers have pointed out that if marketing is to develop as a discipline and contribute to solving complex business and societal challenges, it should question the neoclassical view of markets and develop its own theory of markets. Efforts in this direction indicate an emerging view of markets as dynamic, subjective, and subject to multiple change efforts. However, the neoclassical view of objective, detached, and deterministic market still influences the dominant models used to describe market change. We argue that in order to better understand market dynamics, both academics and practitioners need new concepts and constructs that go beyond existing linear process and development stage models. We seek to contribute to improved understanding of markets by studying a special characteristic of markets that enables market dynamics. Borrowing a term used by Alderson (1957: 277), we propose that markets are characterized by plasticity, that is, a "potentiality for being remolded and responding in a different way thereafter." Even though the plasticity concept was introduced into the marketing literature nearly 60 years ago, the plastic character of markets remains underresearched. This article investigates the meaning and manifestations of market plasticity, drawing analogies from the physical, natural, and social sciences. We define market plasticity as the market's capacity to take and retain form and propose that the dialectic between market stability and market fluidity lies at the heart of market change.
