Industry 4.0: Emerging themes and future research avenues using a text mining approach
The existing literature provides a 'piecemeal' approach to our understanding of Industry 4.0 as a technological revolution'. However, such an approach leads to scattered literature and the possibility (or risk) that the focus could spin out of control in terms of the existing themes and future research trends. Consequently, the aim of this research is twofold: (i) to identify the main overarching themes discussed in the past and track their evolution over time, and (ii) propose a future research agenda for each overarching theme that considers the multidisciplinary nature of research efforts made on the topic. To reach the first objective, a method based on text mining was implemented. To reach the second one, a review based on recent and relevant paper was made for each overarching theme. Text mining suggests four overarching themes: (i) business, (ii) operations, (iii) technological solutions and (iv) work and skills. 'Business' includes studies that investigate the impact of Industry 4.0 on business perspectives and they suggest that governments and industries have a change in manufacturing perspective and attempt to benefit from this industrial revolution wave. 'Operations' includes studies investigating the impact of Industry 4.0 new technologies on production, logistics, and supply-chain processes. Manuscripts belonging to 'Technological solutions' discuss technological solutions at the core of Industry 4.0. 'Work and skills' stream of literature attempts to under the human element lurking behind the scene of Industry 4.0 regarding opportunities and implications. Finally, the paper suggests a future research agenda for each overarching theme, thus paving the way for new research on the topic
The Host Canceled My Reservation! Impact of Host Cancelations on Occupancy Rate in the P2P Context: A Signaling Theory Perspective
The business of hosts in peer-to-peer (P2P) accommodation sharing has become an important source of revenue for individuals in many economies. However, there is a dearth of studies on hosts, specifically on the factors that affect host performance (i.e., occupancy rates). Drawing on the signaling theory and the source credibility theory and using a dataset of 41 610 reviews of 7004 Airbnb listings, we investigated the impact of cancelation rate—that conspicuously signals how many times a host has canceled a pre-existing reservation—on the host occupancy rate. Furthermore, we investigate the role of source credibility signals in reducing the impact of host cancelations. The results show that host signals of reputation, responsiveness, and expertise minimize the negative effect of cancelations on the occupancy rate. Theoretically, we advance the academic literature on credibility signals in P2P platforms and their moderating role on host performance. Managerially, the study helps P2P hosts in understanding the role of signals on occupancy rate
Breast imaging: beyond the detection
Breast cancer is a heterogeneous disease nowadays, including different biological subtypes with a variety of possible treatments, which aim to achieve the best outcome in terms of response to therapy and overall survival. In recent years breast imaging has evolved considerably, and the ultimate goal is to predict these strong phenotypic differences noninvasively. Indeed, breast cancer multiparametric studies can highlight not only qualitative imaging parameters, as the presence/absence of a likely malignant finding, but also quantitative parameters, suggesting clinical-pathological features through the evaluation of imaging biomarkers. A further step has been the introduction of artificial intelligence and in particular radiogenomics, that investigates the relationship between breast cancer imaging characteristics and tumor molecular, genomic and proliferation features. In this review, we discuss the main techniques currently in use for breast imaging, their respective fields of use and their technological and diagnostic innovations
Family firms and collaborative innovation: present debates and future research
Purpose – The purpose of this paper is threefold: first, to identify the unique characteristics of family firms in terms of the ability to manage and the willingness to engage in collaborative innovation; second, to investigate the existence of contingent factors affecting the heterogeneity of family firms’ behavior regarding these dimensions; and third, to propose a future research agenda. Design/methodology/approach – This study consists of a systematic literature review. Findings – Based on the results of a systematic review, the authors explain why family firms have a different behavior in terms of collaborative innovation if compared to the non-family counterparts and, following the contingent-based perspective, the authors also explain how different contingent factors can contribute to cause the heterogeneity of family firms’ behavior when facing collaborative innovation. Finally, the authors present a research agenda aimed at stimulating and guiding future research. Research limitations/implications – The main limitation of the review is the wide definition of collaborative innovation provided at the beginning of the manuscript, in the introduction. In fact, with the aim of including all the studies dealing with collaborative innovation in the family firms’ context, the authors adopt a broad definition of external collaborative innovation that encompasses each process by which organizations work together to achieve an innovation outcome. Originality/value – To the knowledge, this is the first systematic review addressing this relevant topic and proposing a future research agenda. The authors believe it could represent an important guide (but also a stimulus) for scholars interesting in the topic
The influence of open innovation on firm performance
Innovation is crucial for growth and business development, and represents a reliable way through which to gain competitiveness within the marketplace. Open innovation is expressed through three different processes: the acquisition of external technology (inbound innovation); the external exploitation of technology (outbound innovation); and coupled innovation. Based on a comprehensive and systematic review of the literature best able to detect the main thematic areas of the research topic, the aim of this paper is to investigate how the paradigm of open innovation influences firm performance and to provide suggestions for future research avenues
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Negative signals on Peer-to-Peer platforms: The impact of cancellations on host performance across different property types
Scholars investigated the factors enhancing Airbnb hosts' performance; however, less research focused on negative signals, such as host cancellation messages. Cancellations are a negative signal that conspicuously reveals the number of times a host has canceled a pre-existing reservation. Drawing upon signaling theory and product involvement, we argue that cancellation signals have a negative impact on host occupancy, but this impact is moderated by the level of involvement associated with the accommodation type (i.e., private room, shared room, entire apartment). The study used a dataset of 31,778 reviews of 6384 Airbnb listings. The results show that accommodation type moderates the relationship, that is, the impact of cancellations is stronger for higher involvement accommodations (entire apartment) versus low involvement ones (shared rooms). This study ad-vances the literature on negative signals and helps P2P managers understand the impact of cancellations on their revenues
