A method of detecting emerging trends in research topics

Purpose:This paper proposes a method of detecting emerging trends in research topics from a more micro perspective.Design/methodology/approach:Through co-word clustering to identify research topics and analyzing position changes of topic words in the keywords life-cycle diagram during different time periods,we detected emerging trends in research topics from a more micro perspective.I'he method was applied to the field of nanotechnology to verify its effectiveness and practicability.Findings:The results show that this method can be used to detect emerging trends in research topics from a more micro perspective,as it divides keywords into five categories:Potential keywords,emerging keywords,hot keywords,stable keywords and recession keywords,through which more details of topic changes can be found.Research limitations:We used keywords provided by authors and database indexers for keywords extraction.But this approach may lead to the problem of 'indexer effect'.The method may have a limited effect when applied to a disciplinary domain such as mathematics,which evolves slowly.Practical implications:This study provides information analysts with insights into the way to better understand specialty areas of a discipline domain and formulate research policies and strategic plans.Originality/value:This study contributes to the current literature by proposing a new method,which can detect emerging trends in research topics from a more micro perspective.

Systematic Literature Review on Cloud Computing Security: Threats and Mitigation Strategies

Cloud computing plays a significant role in modern information technology, providing organizations with numerous benefits, including flexibility, scalability, and cost-efficiency. However, it has become essential for organizations to ensure the security of their applications, data, and cloud-based networks to use cloud services effectively. This systematic literature review aims to determine the latest information regarding cloud computing security, with a specific emphasis on threats and mitigation strategies. Additionally, it highlights some common threats related to cloud computing security, such as distributed denial-of-service (DDoS) attacks, account hijacking, malware attacks, and data breaches. This research also explores some mitigation strategies, including security awareness training, vulnerability management, security information and event management (SIEM), identity and access management (IAM), and encryption techniques. It discusses emerging trends in cloud security, such as integrating artificial intelligence (AI) and machine learning (ML), serverless computing, and containerization, as well as the effectiveness of the shared responsibility model and its related challenges. The importance of user awareness and the impact of emerging technologies on cloud security have also been discussed in detail to mitigate security risks. A literature review of previous research and scholarly articles has also been conducted to provide insights regarding cloud computing security. It shows the need for continuous research and innovation to address emerging threats and maintain a security-conscious culture in the company.

KnowledgeMapping of Hybrid Solar PV andWind Energy Standalone Systems: A Bibliometric Analysis

Renewable energy is becoming more attractive as traditional fossil fuels are rapidly depleted and expensive,and their use would release pollutants.Power systems that use both wind and solar energy are more reliable and efficient than those that utilize only one energy.Hybrid renewable energy systems(HRES)are viable for remote areas operating in standalone mode.This paper aims to present the state-of-the-art research on off-grid solar-wind hybrid energy systems over the last two decades.More than 1500 published articles extracted from the Web of Science are analyzed by bibliometric methods and processed by CiteSpace to present the results with figures and tables.Productive countries and highly cited authors are identified,and hot topics with hotspot articles are shown in landscape and timeline views.Emerging trends and new developments related to techno-economic analysis and microgrids,as well as the application of HOMER software,are predicted based on the analysis of citation bursts.Furthermore,the opportunities of hybrid energy systems for sustainable development are discussed,and challenges and possible solutions are proposed.The study of this paper provides researchers with a comprehensive understanding and intuitive representation of standalone solar-wind hybrid energy systems.

Global knowledge domain and prospects in tuna research:A bibliometric analysis

Tunas are among the most economically important fish species and play critical roles in food composition and nutrition of humans.As apex predators,they also keep the marine ecosystem healthy and balanced.Both natural and human factors influence the status of this important marine resource and their habitats.There is a large cadre of studies on how tunas are of great significance to the exploitation and management of their fisheries,yet there are few summaries of this research.We aimed to quantitatively and qualitatively synthesize the global knowledge structure and emerging trends in tuna research using bibliometric software.References with"Tuna","Katsuwonus",or"Thunnus"as the subject in the Web of Science Core Collection Database from 1995 to 2019 were visually analyzed using CiteSpace.Publication rate and output,active countries,institutions,authors,and co-cited references were performed.Results suggested that the number of international tuna research papers increased significantly between 2000 and 2010,as a considerable number of high-impact articles emerged during this period.Researchers paid more attention to 19 main topics during this period,notably"overfishing","bycatch","climate change","marine pollution",and"fish management",which all posed potential risks and challenges to tuna survival.Future research should emphasize resolving these challenges and building international cooperation for the proper management of tuna populations.
