Monitoring the developmental trend and competitive landscape of natural gas hydrate through patent analysis.

Natural gas hydrate (NGH) is a significant alternative energy resource in achieving carbon neutrality. The developmental trend and competitive landscape of NGH exploitation and production are crucial for policymakers in government, managers of enterprises, and researchers. This study introduces a novel framework for conducting an in-depth analysis of NGH, integrating patentometrics, technology evolution, and correlation relationships to monitor developmental trends and competitive landscape through patent analysis. The results indicate that China, the USA, and Japan have distinct technology advantages. Current technological developments in the NGH field focus primarily on extraction technologies, equipment, and processing systems. The co-opetition analysis among countries reveals that the most extensive international cooperation network is primarily in Europe and the USA, with national partnerships in Asia concentrated in China and Japan. Institutional cooperation remains limited, primarily within universities in China, while both the USA and Japan foster collaboration between enterprises. The competitive landscapes of key NGH-related technologies among countries and institutions are also examined. This study contributes not only to monitoring the developmental trend and competitive landscape in NGH but also to providing policy recommendations for government and enterprises regarding strategic management and collaborative innovation.

Tourism cooperation in the Belt and Road Initiative from economic and spatial insights.

This study examines the potential benefits of cooperation among Belt and Road Initiative (BRI) countries in achieving common goals within the international tourism cooperation network. Despite its significance, limited research has been conducted on this topic in terms of economic and spatial insights. To address this gap, we utilized the gravity model, social network, and quadratic regression. The revealed findings suggest that while the intermediary function among BRI countries is declining, the tourism cooperation network is gradually strengthening. Furthermore, reducing the gap between the governance and consumption levels of BRI countries can improve the network. The study offers new insights into the BRI tourism cooperation network, which could be critical for the future growth of regional tourism.

Shifting sands: How change-point and community detection can enrich our understanding of international politics

When and how do international political arrangements change? International relations scholars have long examined the nature of shifts in international alliance and cooperation networks, often arguing that times of disruption in the international system are the most precarious for peace. In this research note, we rely on innovations in change-point and community detection methods to endogenously examine the timing and nature of shifts in country-to-country relationships through defense cooperative agreements. Using new methodical innovations from network science, we can see how countries move through different communities over time, changing the nature of polarity in the system. This empirical approach can help provide insights into determinants of peace, vulnerabilities in the international system, and potential aggressors in world politics.

Public–Private Partnership (PPP) in Road Infrastructure Projects: A Review of Evolution, Approaches, and Prospects

Public–private partnerships (PPPs) are a widely used procurement method for constructing, maintaining, and operating roads, constituting an alternative to the traditional public works model (TPW). This is because the efficiency of the PPP model has been highlighted over the TPW model. This study carried out a bibliometric analysis of 734 public articles from Scopus on PPPs in road infrastructure projects between 1993 and 2022. The results allow us to identify the general characteristics of the research; the most relevant articles; the most productive journals; and the most prolific authors, institutions, and countries and their main international cooperation networks, as well as to detect the main current research topics, which are: financial management, costs and pricing systems, privatization of transport infrastructure services, and sustainability. Consequently, this study provides a comprehensive overview of research on PPPs in road infrastructure projects over the last 30 years. This can reinforce and complement previous bibliometric analyses on PPPs in road infrastructure projects.

Crisis exercise in the framework of coastal geohazards: Experience in the Balearic islands (Spain)

Within an international cooperation network (France, Spain and Portugal) involving researchers, first responders and civil protection authorities, a crisis exercise was held simultaneously in Mallorca and Ibiza (Balearic Islands, Spain). The objectives were to test crisis management procedures defined by operational actors, integrating new developed scientific tools related to landslides and rockfalls, as well as the internal relationship with the new created Technical Advisory Committee. The initiative included a training module for all stakeholders before the exercise explaining the scientific tools used for supporting the decision-making process during the exercise, as well as a field trip in the Tramuntana range in Mallorca to gain first-hand knowledge of the geological hazards threatening the region, mainly rockfalls. More than 70 people were involved in the training exercise, including researchers, civil protection, civil guard, municipalities, representants of the autonomous regions, local and regional crisis management managers from different French and Spanish entities, etc. At the end of the exercise, a joint analysis was made of the strengths and weaknesses found during the development of the exercise and propositions of improvements were made. Local and regional authorities concluded that, thanks to the exercise, they are better prepared to deal with georisks induced by extreme weather, mainly landslides and rockfalls. The scientific community understood the type of operational products they should develop for decision support during disaster risk crises. This experience emphasizes the need to create stronger links between the scientific community and civil protection stakeholders.

A comparative study of international and Chinese digitization from the perspective of mapping knowledge domains

As a powerful tool to promote sustainable development, digitization profoundly impacts economic and social development. Systematically reviewing and performing econometric analyses of the literature in the digitization field can provide reference for the next stage of research. Based on the theory of bibliometric citation analysis and the knowledge domain mapping method, this study takes Web of Science United States (WOS) and Chinese Social Science Citation Index (CSSCI) as data sources and uses CiteSpace analysis tools to carry out data mining and visual comparative analysis on Chinese and international research hotspots, knowledge structure, and scientific research co-operation in the digitization field. The results show that (1) Chinese research hotspots and frontiers focus on digitization practice, while international research hotspots and frontiers focus on digitization theory, (2) that there is an ageing fault in the classic Chinese digitization literature, and the classic international digitization literature constantly changes with research hotspots, (3) and that the United States, Germany, and the United Kingdom are at the centre of the international digitization scientific research cooperation network. There is close cooperation among international institutions and authors. There are few contacts between Chinese institutions. Chinese authors have less cooperation with authors from other countries in the world.

A bibliometric analysis of the impact of COVID-19 social lockdowns on air quality: research trends and future directions.

Social lockdowns improved air quality during the COVID-19 pandemic. Governments had previously spent a lot of money addressing air pollution without success. This bibliometric study measured the influence of COVID-19 social lockdowns on air pollution, identified emerging issues, and discussed future perspectives. The researchers examined the contributions of countries, authors, and most productive journals to COVID-19 and air pollution research from January 1, 2020, to September 12, 2022, from the Web of Sciences Core Collection (WoS). The results showed that (a) publications on the COVID-19 pandemic and air pollution were 504 (research articles) with 7495 citations, (b) China ranked first in the number of publications (n = 151; 29.96% of the global output) and was the main country in international cooperation network, followed by India (n = 101; 20.04% of the total articles) and the USA (n = 41; 8.13% of the global output). Air pollution plagues China, India, and the USA, calling for many studies. After a high spike in 2020, research published in 2021 declined in 2022. The author's keywords have focused on "COVID-19," "air pollution," "lockdown," and "PM25." These keywords suggest that research in this area is focused on understanding the health impacts of air pollution, developing policies to address air pollution, and improving air quality monitoring. The COVID-19 social lockdown served as a specified procedure to reduce air pollution in these countries. However, this paper provides practical recommendations for future research and a model for environmental and health scientists to examine the likely impact of COVID-19 social lockdowns on urban air pollution.

The Peruvian Alzheimer Disease Initiative (PeADI): An international effort model to increase diversity in AD research (S15.002)

<h3>Objective:</h3> We have developed an international collaborative research initiative to ascertain a Peruvian cohort for AD and other related dementias for genetic studies of Amerindian individuals. <h3>Background:</h3> Peru is one of the five largest countries in Latin America and harboring a high Amerindian ancestry component in this population. The Latin American population, including Peruvians, are underrepresented in research studies of AD. <h3>Design/Methods:</h3> PeADI was developed to recruit and enroll Peruvian adults aged 65 and older to a comprehensive genetic AD study. Individuals will get whole genome sequencing and plasma biomarkers. Participants included cases with AD and ADRD, healthy controls as well as multiplex AD families. Since 2019, we have established a multisource ascertainment approach including recruitment at main hospitals, outreach community activities and more recently due to the COVID19 pandemic remote recruitment and home visits in Lima, the capital city. Our recruitment has expanded to three regions from the Andes highlands (Puno, Huancayo, Cusco) and one region from the southern coast (Tacna). All participants are enrolled using a standard clinical and cognitive protocol administered by neurologists and neuropsychologists. <h3>Results:</h3> As of September 2022, we have enrolled 132 AD and other dementia cases, 292 controls and 6 multiplex AD families. While the majority of participants was recruited in Lima,45% controls and 7% of cases have been recruited in regions outside Lima. We have confirmed a significant association between APOE and AD in Peruvian Population higher than we have observed in non-Hispanics. In addition to ascertainment activities, we are working closely with the respective sites to develop a network and resources for AD research across Peru. To date, we have developed local research capacities within each region, including training opportunities for investigators, coordinators and lab technicians, and basic equipment for all regions. <h3>Conclusions:</h3> PeADI study shows the importance of equitable international north-south cooperation and local network cooperation to increase representation of understudied admixed populations to help us understand Amerindian ancestry in drug target discovery. <b>Disclosure:</b> Dr. Illanes-Manrique has nothing to disclose.

The impact of international technical cooperation in new energy industry on carbon emissions: evidence from the top 30 countries in the global innovation index.

International cooperation has become a global consensus to solve environmental problems. This paper selects the top 30 countries in the global innovation index as the research sample, based on Patent Cooperation Treaties (PCT) data jointly applied in the field of new energy, constructs the international technical cooperation network, and uses the fixed effect panel regression model to verify the influence of international technical cooperation of new energy industry on carbon emission intensity. The results show that the USA, Germany, the UK, France, and the Netherlands are at the center of the network. International technological cooperation in new energy industry has a significant negative impact on carbon emission intensity. The convening of the United Nations Climate Change Conference in Copenhagenhas accelerated global industrial upgrading, and the effect of international technical cooperation in new energy on carbon emission reduction has been strengthened. In addition, the level of economic development, international trade, and research and development (R&D) are also important factors affecting carbon emission intensity. Countries with high network centrality should give full play to their network influence to promote global cooperation in the field of new energy and achieve carbon mitigation targets by signing more environmental agreements.
