Tracing knowledge evolution flows in scholarly restaurant research: a main path analysis.

Restaurant research has received significant attention globally. This article aims to examine the evolution and the knowledge structure of restaurant research over the past decades. We also investigate the restaurant research hotspots and knowledge diffusion paths based on 1489 articles extracted from the Web of Science database. Furthermore, we conduct a keyword co-occurrence network analysis and four different types of main path analyses to scrutinize the historical formation of the restaurant research. Results revealed that restaurant research mainly focused on five research themes: consumer behavior, consumer satisfaction, social media, green restaurants, and authenticity. While consumer behavior has been the mainstream topic, the focus of this line of research has recently shifted from traditional to luxury and ethnic restaurants. Furthermore, our analysis has detected several recent changes in response to the COVID-19 pandemic. By examining the knowledge structure of restaurant research, we reveal its knowledge diffusion paths and provide avenues for future research in this vast and interdisciplinary research field.

Circular Economy Research in the COVID-19 Era: a Review and the Road Ahead

The onset of the Coronavirus Disease 2019 (COVID-19) pandemic has resulted in a major crisis that has severely impacted numerous economic, environmental, and social aspects of human life. During the pandemic, the potential of the circular economy (CE) has gained increasing attention as a prospective remedy for numerous sustainability problems. This systematic literature review charts CE research in the COVID-19 era. To this end, 160 journal articles were selected from the Scopus database. The performance indicators of the literature were determined and described through a bibliometric analysis. Moreover, the conceptual structure of CE research was identified via a keyword co-occurrence network. Based on bibliographic coupling, the focus of CE research in the COVID-19 era revolves mainly around five thematic areas, including: (1) waste management;(2) digitalization and sustainable supply chain management;(3) the impact of COVID-19 on food systems;(4) sustainable development goals, smart cities, and bioeconomy;and (5) closed-loop supply chains. Overall, this review contributes to enriching the literature by determining the main thematic areas and future research directions that can help to advance the transition to the CE and reduce the impact of COVID-19 and similar disasters in the future.

The role of blockchain technology in the transition toward the circular economy: Findings from a systematic literature review

The circular economy (CE) has emerged as a paradigm to protect the environment and the well-being of future generations. In parallel, Blockchain technology (BC) has emerged as a critical enabler for accelerating the transition toward a CE. In order to understand and summarize prior research on the role of BC in the CE, we conducted a systematic literature review (SLR) of 70 seminal articles published before July 2022. Six main themes emerged: a) CE approaches and practices, b) BC and the integration of the Internet of Things (IoT), c) sustainable supply chain management, d) BC and the CE in the COVID-19 era, e) sector-specific BC applications, and f) barriers to BC adoption in the CE. Furthermore, we develop a comprehensive framework that integrates stakeholders, strategies and practices, industrial sectors and a BC-enabled CE.

Exploring Food Supply Chain Trends in the COVID-19 Era: A Bibliometric Review

Recently, the food supply chain (FSC) has been severely disrupted due to the COVID-19 pandemic, putting the vital flow of food products from farmers and producers to the ultimate consumers at risk. Furthermore, due to the pandemic, several food organizations have been prompted to rethink their strategies for the future. Although the literature on FSC research in the COVID-19 era is increasing, no attempt has been made to summarize this stream of research using bibliometric techniques. This paper fills this knowledge gap and looks at the current scholarly discourse around the FSC and COVID-19. Applying bibliometric techniques, 287 journal articles were extracted from Scopus and analyzed to determine the temporal evolution of FSC research, the most productive journals, researchers, countries, and the most relevant keywords and publications. To construct a keyword co-occurrence network and categorize the relevant literature, we used the computer program VOSviewer. The findings demonstrate the rapid expansion of FSC research during the COVID-19 pandemic. In addition, the top authors, publications, and nations for scientific output were also determined. Keyword co-occurrence network and detailed qualitative analysis both illustrate that FSC research revolves around six main themes: the impact of COVID-19 on the FSC and agriculture, FSC resilience, food waste and insecurity, fisheries and aquaculture, blockchain technology, and governance and innovation. This study represents the first effort to map worldwide FSC research in the COVID-19 era and draw on a comprehensive collection of journal articles and bibliometric approaches. It offers academics, practitioners, and decision-makers a snapshot of the state of the art in the FSC field and points to where further research is needed.

The big picture on Instagram research: Insights from a bibliometric analysis

Instagram is a leading social network for information sharing and communication. Rigorous studies are missing that leverage bibliometric techniques to comprehensively portray the field. To fill this knowledge gap, this study carries out a holistic bibliometric and network analysis of Instagram research, illustrating the dynamic evolution from 2013 to 2021. On the basis of 2,242 publications from the Web of Science database, which were authored by 6,206 researchers, this study identifies the most prominent scholars and articles in the literature. Furthermore, it analyzes diverse bibliometric networks, such as citation, co-citation, collaboration and keyword co-occurrence networks, and presents two intellectual structure maps (i.e., conceptual structure map, thematic map). The results indicate that the number of academic studies about Instagram has been growing significantly over time and that the dominant topics are the psychological motivation of Instagram use, the COVID-19 pandemic, Instagram marketing, social media platforms, and healthcare.

Knowledge Diffusion of the Internet of Things (IoT): A Main Path Analysis.

The Internet of Things (IoT) is a concept that has attracted significant attention since the emergence of wireless technology. The knowledge diffusion of IoT takes place when an individual disseminates his knowledge of IoT to the persons to whom he is directly connected, and knowledge creation arises when the persons receive new knowledge of IoT, which is combined with their existing knowledge. In the current literature, several efforts have been devoted to summarising previous studies on IoT. However, the rapid development of IoT research necessitates examining the knowledge diffusion routes in the IoT domain by applying the main path analysis (MPA). It is crucial to update prior IoT studies and revisit the knowledge evolution and future research directions in this domain. Therefore, this paper adopts the keyword co-occurrence network and MPA to identify the research hotspots and study the historical development of the IoT domain based on 27,425 papers collected from the Web of Science from 1970 to 2020. The results show that IoT research is focused on IoT applications for smart cities, wireless networks, blockchain technology, computing technologies, and AI technologies. The findings from the MPA address the need to explore the knowledge evolution in the IoT domain. They also provide a valuable guide to disseminate the knowledge of IoT among researchers and practitioners, assisting them to understand the history, present and future trends of IoT development and implementation.

Covid-19 and the food chain? Impacts and future research trends

Background: Throughout history, the world has witnessed natural disasters affecting businesses and societies with varying degrees of disruption. COVID-19 (henceforth C19) constituted a significant system shock and a stark reminder of the fragility and sensitive nature of supply chains. The pandemic has exerted considerable societal and economic pressure and has had an adverse impact on food supply chains in particular. Many food processing operations were forced to alter activities or close temporarily due to outbreaks. Societal lockdowns, travel restrictions, business closures and quarantine have led to structural changes in the productivity of economies and impacted the mental health and financial wellbeing of citizens. Methods: We present a critical review of the literature to explore the impact of C19 on the food supply chain. We collected data from journal articles retrieved from a leading scientific database (i.e., Scopus), books, chapters, conference proceedings, reports, and a variety of Internet websites. For the literature search, we used the following words;"COVID-19" and "food". Results and conclusions: The findings of the review suggest that the C19 pandemic poses unprecedented challenges for food supply chains. We reveal that C19 has raised food insecurity and food safety concerns, increased supply chain and logistics costs and radically changed consumer behavior. On the positive side, the pandemic has improved awareness of food waste and the importance of self-grown foods. We generated nine research propositions to foster future academic research. Our study also highlighted the need to advance this literature and calls for increased attention from the supply chain management and logistics community to further analyse and quantify the impact of C19 on the food chain.Alternate abstract: Streszczenie: Wstęp: W ujęciu historycznym, świat już nieraz doświadczał naturalnych katastrof, które miały wpływ w różnym nasileniu na biznes oraz społeczeństwo. COVID-19 (C19) spowodował istotny szok dla systemu oraz przypomniał o kruchości i wrażliwości łańcuchów dostaw żywności. Pandemia wywarła istotny wpływ w szczególności na tą część ogólnego łańcucha dostaw. Wiele przedsiębiorstw produkujących żywność musiało zmienił sposób swojej działalności lub czasowo ją przerwać. Lockdown, ograniczenia w podróżowaniu, zamknięcie części działalności gospodarczej i kwarantanna doprowadziły do strukturalnych zmian w produktywności ekonomii i wpłynęły na zarówno psychiczne zdrowie jak i poziom zamożności obywateli. Metody: W pracy zaprezentowany jest krytyczny przegląd literatury dotyczącej wpływu C19 na łańcuch dostaw żywności. Dane zostały zebrane na podstawie przeglądu artykułów prasowych z wiodących baz naukowych (np. Scopus), książek, rozdziałów, materiałów konferencyjnych, raportów oraz różnych stron internetowych. Przy wyszukiwaniu tych prac, słowami kluczowymi były słowa: „COVIS-19” oraz „żywność”. Wyniki i wnioski: Uzyskane wyniki badań sugerują, że pandemia C19 jest niespotykanym wyzwaniem dla łańcuchów dostaw żywności. C19 spowodował obniżenie bezpieczeństwa łańcucha dostaw żywności, zwiększył koszty logistyki i radykalnie zmienił upodobania konsumentów. Jak pozytywny efekt, pandemia zwiększyła świadomość marnotrawstwa żywności i istotność niezależności produkcji żywności. Zostały opracowane propozycje dalszych kierunków badań naukowych w tym obszarze. Pokreślono potrzebę tych badań oraz rozpracowanie wpływu C19 na łańcuch dostaw żywności w kontekście zarządzania łańcuchem dostaw.
