Researchers are developing digital solutions for agriculture. Humanity has perfected agriculture throughout history because this activity is fundamental to our existence. The agricultural sector is currently incorporating new technologies from other areas. This phenomenon is agriculture 4.0. However, a challenge to research is the integration of technologies from different knowledge fields, and this has caused theoretical and practical difficulties. Thus, our purpose with this study has been to understand the core agriculture 4.0 research themes. We have used a bibliometric analysis, and guided the data collection by the PRISMA protocol. VosViewer and Bibliometrix software generated the results. We found two main research fronts, one focussed on agriculture 4.0 development, and another on the impacts of agriculture 4.0, which may be positive or negative. We found 21 main keywords or topics researched in agriculture 4.0 related to these research fronts. These themes are within five different axes. We managed to establish a good understanding of the topics around agriculture 4.0. Future studies could focus on the responsible development of digital solutions for agriculture. This is because the social, environmental, and economic impacts of these new solutions may be positive or negative. We conclude that digital agriculture is the node technologies integration for the automation of agricultural activities.

 

 

Climate change and global warming interconnected with the new contexts created by the COVID-19 pandemic and the Russia-Ukraine conflict have brought serious challenges to national and international organizations, especially in terms of food security and agricultural planning. These circumstances are of particular concern due to the impacts on food chains and the resulting disruptions in supply and price changes. The digital agricultural transition in Era 4.0 can play a decisive role in dealing with these new agendas, where drones and sensors, big data, the internet of things and machine learning all have their inputs. In this context, the main objective of this study is to highlight insights from the literature on the relationships between machine learning and food security and their contributions to agricultural planning in the context of Agriculture 4.0. For this, a systematic review was carried out based on information from text and bibliographic data. The proposed objectives and methodologies represent an innovative approach, namely, the consideration of bibliometric evaluation as a support for a focused literature review related to the topics addressed here. The results of this research show the importance of the digital transition in agriculture to support better policy and planning design and address imbalances in food chains and agricultural markets. New technologies in Era 4.0 and their application through Climate-Smart Agriculture approaches are crucial for sustainable businesses (economically, socially and environmentally) and the food supply. Furthermore, for the interrelationships between machine learning and food security, the literature highlights the relevance of platforms and methods, such as, for example, Google Earth Engine and Random Forest. These and other approaches have been considered to predict crop yield (wheat, barley, rice, maize and soybean), abiotic stress, field biomass and crop mapping with high accuracy (R2 ≈ 0.99 and RMSE ≈ 1%). © 2022 by the authors.

 

 

The use of digital tools is transforming scientific production processes and their impacts. In this article we evaluate to what extent digitalization in science has reached Latin American scientific activity and what have been its effects. For this purpose, we use bibliometric data from three medium-sized Latin American countries that have an important scientific trajectory: Argentina, Chile, and Colombia, focusing the analysis on four disciplines: biological and agricultural sciences, earth and planetary sciences, environmental sciences, and decisional sciences. We find that digitalization has been growing for the past 25 years, but the gap with leading countries has only narrowed slightly. Likewise, the incidence of digitalization varies by discipline. In terms of benefits associated with digitalization, our results show that articles that use digital science practices or tools have greater academic impact (have more citations), more collaboration (more co-authors), and more internationalization (authors from a larger number of countries). In other words, in these disciplines and in these countries, digitalization has managed to increase the visibility of research, potentially its quality and, thus, the social returns of the resources invested. Networks have also been expanded, thus promoting a better use of collective intelligence and the integration of local research problems into a global agenda, potentially increasing the resources devoted to research in these countries.

 

 

A bibliometric analysis based on the Scopus database was carried out to summarize the global research related to selenium in drinking water from 1990 to 2021 and identify the quantitative characteristics of the research in this period. The results from the analysis revealed that the number of accumulated publications followed a quadratic growth, which confirmed the relevance this research topic is gaining during the last years. High research efforts have been invested to define safe selenium content in drinking water, since the insufficient or excessive intake of selenium and the corresponding effects on human health are only separated by a narrow margin. Some important research features of the four main technologies most frequently used to remove selenium from drinking water (coagulation, flocculation and precipitation followed by filtration; adsorption and ion exchange; membrane-based processes and biological treatments) were compiled in this work. Although the search of technological options to remove selenium from drinking water is less intensive than the search of solutions to reduce and eliminate the presence of other pollutants, adsorption was the alternative that has received the most attention according to the research trends during the studied period, followed by membrane technologies, while biological methods require further research efforts to promote their implementation.

 

 

Cyberbullying prevalence is increasing in the world, being a form of abuse that follows victims into their most intimate settings. Cyberbullying affects victims’ mental health, self-esteem, emotions, and academic performance. Cyberbullies present low levels of self-control and empathy. This research aimed to map scientific research on Cyberbullying and the Psychological Dimensions of the Self. A bibliometric analysis of scientific documents published in journals indexed in the Web of Science (WoS) was performed. Traditional bibliometric laws were applied and VOSviewer was used to generate visualizations. The annual publications followed exponential growth. Computers in Human Behaviour was the journal with the most publications. Researchers from the USA and Spain were the most prolific. Sameer Hinduja and Justin Patchin were the most cited authors. Hence, there is a growing interest among researchers in Cyberbullying and the emotional aspects of children and adolescents. The USA and Spain were the leading countries in research on this subject. Rosario Ortega-Ruiz, Sameer Hinduja and Justin Patchin were the most prolific and influential authors.

 

 

Purpose: In recent years, the Knowledge-Based Economy (KBE) has been an emergent field related to Information and Communication Technologies (ICTs). In current business models, organizations need to be part of the digital transformation and create value for customers, which has caused an increase in the number of scientific publications on the KBE. This study aims to analyze the research trends of the scientific literature on the KBE published between 1986 and 2021. Design/methodology: A bibliometric analysis was conducted using the Scopus database. The results were analyzed based on quantity, impact, and structure indicators and topics. In addition, this paper proposes a research agenda for future studies in this field. Findings: The study of the KBE has attracted the interest of the scientific community, especially in 2006, 2010, and 2011. This literature review shows that developed countries (e.g., Poland, Romania, the United Kingdom, the United States, and Germany) have researched this field the most. Terms such as knowledge-based systems, knowledge management, and information management have become more common in the literature and are setting trends. These terms refer to essential components for the advancement of the KBE as an approach that can dynamize the economic development of organizations and countries. Originality/value: This study contributes to the literature because it analyzes the theoretical evolution of the KBE field. In addition, it proposes an agenda for future studies to advance the research fields related to the Triple Helix model of innovation in developing countries

 

 

Objective: To carry out a mapping of studies on innovation and public policies, presenting an overview of the scientific discussion on the topic to suggest proposals for future studies. Design/methodology/approach: A bibliometric study, through exploratory factor analysis, with the objective of identifying the path that the phenomenon takes. For this, we use the techniques of citation, co-citation and bibliographic coupling. Originality: Given the economic, social and technological importance of innovation, public policies appear as engines of the development of innovation, thus reinforcing the need to identify unexplored paths through the mapping of studies on the theme to identify unexplored paths. Results: We identified the basis on which the theme studied was developed. Thus, three factors were observed: Economic Development, Innovation Ecosystems and State Participation. In the coupling analysis, we identified four factors, namely: Entrepreneurship, Changes in Public Policies, Networks and Clusters and Knowledge Source. Looking to the future, some study trends were presented, highlighting a new research agenda. Theoretical and methodological contributions: We present some study trends on innovation and public policies, warranting a new research agenda. Management contributions: This research enables managers and decision makers to understand the aspects regarding the theme, so that they can develop strategic innovation actions with the support of public policies.

 

 

The literature recognizes and correlates the power of innovation and entrepreneurship as enabling factors for the economic development of localities. Aiming to examine the prevalence of such relationships, this paper aims to explore the development phenomenon of Brazilian cities considered the most innovative and entrepreneurial, aiming to identify the implications of stimulating technological entrepreneurship on the socioeconomic development of these cities. In the initial bibliometric survey on the themes discussed in Brazilian cities, no scientific papers were identified that explored the three constructs simultaneously, and established comparisons that could indicate some kind of relationship between them. Understood as an original gap, this absence inspired the preparation of the present article. To this end, a mixed approach and exploratory-descriptive research was adopted, using as a basis for comparison the Ranking of the Most Innovative Cities; Most Entrepreneurial Cities Index, FIRJAN Municipal Development Index, Human Development and Gini Coefficient. The cities with an outstanding position in one of the analyzed indexes were examined. The theoretical review allowed the formulation of four hypotheses that were tested and compared to the adopted indexes. The results obtained indicate that the most innovative and entrepreneurial municipalities have high Human Development Index, with emphasis on the dimension of Education, indicating that the training of quality human resources is a relevant asset in the context of innovation and entrepreneurship. However, it was not possible to confirm the relationship between innovation and entrepreneurship with economic development in those municipalities, since the cities with the highest economic development did not appear in the ranking of most innovative cities and in the Index of Most Entrepreneurial Cities, which indicates that it is a potentially valuable object for future studies.

 

 

BACKGROUND: The COVID-19 pandemic impacted the Sustainable Development Goals (SDGs). Among these impacts, those related to the SDG 8 can be highlighted. Consequently, the literature has addressed aspects related to economic growth and decent work. OBJECTIVE: This article aimed to evaluate the impact of the COVID-19 pandemic on decent work according to the literature. METHODS: For this, a bibliometric analysis was conducted. Data from Web of Science were collected, and VOSviewer software was used to perform the analysis. RESULTS: Regarding the results, four main clusters that govern the subject were identified. A first cluster (identified in red) evidenced the consequences of the pandemic to the generation of informal work, increasing poverty and the impacts on gender issues. A second cluster (identified in blue) addresses mental health and stress issues, especially for nurses professionals who experience a situation in the COVID-19 pandemic. The green cluster focused on unemployment, precarious employment, and work conditions, which were highly related to coronavirus contagion. Finally, the yellow cluster evidenced the final consequences when there is a substantial public health problem. CONCLUSIONS: The results presented here can be helpful to researchers interested in the, as it allows a broad and condensed view of important information about a relevant topic for sustainable economic development.

 

 

The aim of this investigation is to identify the relationship which can be found in the literature between creative tourism and local development, using a bibliometric inventory made in scientific databases (Academia.edu , Econlit, Google Scholar, CAPES Journals, Redalyc, Scielo.org , SCOPUS, and Web of Science, among others) as research method. In general, it was possible to verify that there is a concern of the authors of the papers analysed in establishing a link between creative tourism and local/regional development, without, however, going very far on this relationship, or, at least, when it came to identifying the impacts of economic, cultural, social and environmental nature. This being said, it seems to be relevant that future research takes a deeper look at the hypothesised relationship between the proposals of creative tourism and the benefits it can bring to local communities.
