In this research, the authors investigate the prevalence, robustness, and possible reasons underlying the polarity of online review distributions, with the majority of the reviews at the positive end of the rating scale, a few reviews in the midrange, and some reviews at the negative end of the scale. Compiling a large data set of online reviews—over 280 million reviews from 25 major online platforms—the authors find that most reviews on most platforms exhibit a high degree of polarity, but the platforms vary in the degree of polarity on the basis of how selective customers are in reviewing products on the platform. Using cross-platform and multimethod analyses, including secondary data, experiments, and survey data, the authors empirically confirm polarity self-selection, described as the higher tendency of consumers with extreme evaluations to provide a review as an important driver of the polarity of review distributions. In addition, they describe and demonstrate that polarity self-selection and the polarity of the review distribution reduce the informativeness of online reviews.

Purpose The purpose of this paper is to examine the degree to which budget and mid-range hoteliers perceive Airbnb as a threat, and the extent to which they are actively responding to the peer-to-peer accommodation business model. Design/methodology/approach The study draws on qualitative data collected through 19 semi-structured interviews with budget and midrange hotel managers in Istanbul, Turkey, covering how they view Airbnb and have responded to Airbnb’s rise. Findings The results suggest that the managers believed they were losing some business to Airbnb, yet they generally neither perceive Airbnb as a serious threat nor were they generally taking concrete strategic measures to respond to Airbnb. Regulatory lobbying against Airbnb and exploiting Airbnb as a new distribution platform were the most common responses, and cutting rate also was commonly seen as a potential competitive strategy. Originality/value The study responds to calls by several scholars for more research addressing the strategies adopted by traditional lodging facilities to protect their market share from Airbnb. This study does so with a specific focus on the budget and midrange hotel segments, which some studies suggest may be particularly vulnerable to Airbnb competition. Also, the limited research addressing Airbnb’s perceived impacts on traditional lodging has been conducted in mature economies, so the topic remains largely neglected in maturing economies like Turkey.

Purpose The purpose of this paper is to identify and delineate research directions that guide future empirical studies exploring how engagement platforms facilitate value co-creation and actor engagement in the context of the sharing economy. Design/methodology/approach The authors adopt a midrange theorizing approach with service-dominant logic as the integrating meta-theoretical perspective to develop a theoretical framework about service platforms, engagement platforms, and actor engagement in information communication technology (ICT) mediated environments. The authors then contextualize the framework for the sharing economy. Findings The authors introduce 20 unique research questions to guide future studies related to service ecosystems, engagement platforms, and actor engagement practices in the context of the sharing economy. Research limitations/implications The sharing economy is an emerging phenomenon that is driven by the development and proliferation of engagement platforms. The engagement platform concept therefore provides a novel perspective for exploration of how ICT can be utilized to facilitate value co-creation and engagement amongst interdependent economic actors in a service ecosystem. Practical implications The purpose of this paper is to guide future academic research, rather than managerial practice. Future research based on the framework can help guide decision-makers to implement and use engagement platforms more effectively. Originality/value This paper offers new insight into the important intersection of ICT and service research, and guides future studies exploring the role of engagement platforms in the context of the sharing economy.

Two-dimensional (2D) layered materials hold great promise for various future electronic and optoelectronic devices that traditional semiconductors cannot afford. 2D pnictogen, group-VA atomic sheet (including phosphorene, arsenene, antimonene, and bismuthene) is believed to be a competitive candidate for next-generation logic devices. This is due to their intriguing physical and chemical properties, such as tunable midrange bandgap and controllable stability. Since the first black phosphorus field-effect transistor (FET) demo in 2014, there has been abundant exciting research advancement on the fundamental properties, preparation methods, and related electronic applications of 2D pnictogen. Herein, we review the recent progress in both material and device aspects of 2D pnictogen FETs. This includes a brief survey on the crystal structure, electronic properties and synthesis, or growth experiments. With more device orientation, this review emphasizes experimental fabrication, performance enhancing approaches, and configuration engineering of 2D pnictogen FETs. At the end, this review outlines current challenges and prospects for 2D pnictogen FETs as a potential platform for novel nanoelectronics.

Purpose This paper explores the design dimensions that foster identity construction, legitimation, and growth of digitally mediated platform ecosystems. Design/methodology/approach A midrange theorizing approach was adopted to assimilate and induct the extant literature on ecosystems, platform business models and innovation, yielding testable propositions on ecosystem design for empirical testing. Findings The paper suggests that decentralized governance, partner engagement and shared context are three dimensions of criticality for designing a distinct platform ecosystem. These design dimensions nurture interactions, transactions, relationships between platform participants and external actors to make ecosystems authentic and legitimate. Decentralization is relevant for inducing flexibility and autonomy of participants on the platform. Engagement impacts the intensity of relationships the platform has with other firms in the ecosystem, while shared context is essential for creating knowledge and harnessing innovation on the platform. Research limitations/implications The paper identifies a set of three testable propositions on ecosystem design for further empirical analysis by ecosystem researchers. Practical implications To achieve future readiness, organizations must become resilient to the market environment. With that intent, traditional businesses are revising their operating models to become more collaborative, integrative and efficient. Adoption of digital initiatives for redesigning towards platform ecosystems will make traditional models more relevant as markets evolve. But as a new organization form, platform ecosystem faces the challenge of legitimacy. Author suggests that managers use the organization design lever to meet the challenge. Originality/value Emergence of platform-based businesses and transformation of existing models to platform ecosystems are impacting today's competitive environment. During initial phases of evolution, ecosystems aim for identity and legitimacy. The authors contribute to organizational aspects of the platform ecosystem design literature by identifying decentralization of governance, engagement and shared context as dimensions of criticality for future-ready platforms. Secondly, these dimensions are associated with identity and legitimation of platform ecosystems. Decentralization is relevant for supply-side producers of goods and services on the platform, engagement has impact on both supply and demand-side participants of platforms, and shared context is essential for knowledge creation and harnessing innovation.
