Studies on the influence of public policies on the regional tourism sector are of high scientific and practical interest, as they offer inputs to guide public management towards strengthening the tourism development of the territories. Through the structural equation model, this study took a sample 99 companies in the tourism sector in Valle del Cauca, Colombia, addressing the relationship between public policy management (PPM) and regional tourism development (RTD), from the perspective of the rational model of business performance. The findings show that the capacity of the state and its entities to comply with the requirements of the organizations, as well as the rigor to take criticism and suggestions for improvement, as a basis to strengthen their management, are the factors that best explain the relationship between the PPM and RTD based on the performance of organizations in the sector, especially focused on increasing market share, productivity, and income. Other findings and practical implications are discussed.

This paper contributes to the understanding of how flexibility in the number of members in a decision-making committee in a multistage project can enhance the accuracy and efficiency of the decisions taken. While most projects typically employ a fixed number of decision makers, the paper demonstrates the advantages of adjusting the committee size according to the project’s varying complexity at different phases of the project. In particular, we show that allowing for flexibility in the size of a committee increases the likelihood of reaching a correct decision under the unanimity rule. We analyze this issue when the decision maker’s competence is independent of the state of nature and when it is not. The results are compared to those under the simple majority rule.

Furthermore, the paper discusses the practical application of blockchain technology in IP registration, management, transaction, and rights protection, highlighting its significant impact on security traceability, transaction cost reduction, and efficiency improvement. Lastly, the article anticipates the future role of blockchain technology in IP protection in e-commerce and believes that with continued technological advancements and enhanced policy support, blockchain will play an increasingly pivotal role in this domain. The paper also proposes potential challenges and solutions that require attention, aiming to foster the healthy and sustainable development of blockchain technology.

Science and technology play an extremely important part in today’s world. They are the key for countries to reach a certain level of economic and social development. Thus, in order to catch up with the common development of mankind, countries have issued their own policies and laws on science and technology activities. National science and technology policies aim to enhance social welfare, foster sustainable development, and advance global scientific and technological progress. Vietnam is considered as one of the countries attaching great importance to science and technology. Therefore, even in the law with the highest legal value—the Constitution has solemnly recognized the position and role of science and technology as the leading national policy, playing a major role in the cause of the country’s socio-economic development. However, in the face of the requirements of sustainable development and the desire for the country’s prosperity and strength, policies and laws on science and technology in particular and policies and laws in general of Vietnam must be perfected and renewed continuously, especially in the context of globalization and sustainable development requirements, modern nation as it is today. Therefore, the article focuses on clarifying the situation of adjusting policies and laws on science and technology in Vietnam during the past, thereby proposing new complete solutions in the coming time. This is the basis for policy makers to refer to in the process of developing policies and laws on science and technology in Vietnam.

Previous studies support the direct relationship between outdoor physical activity and natural spaces in cities. The Active City and Nature concept explores the relationship between urban, green and active environments; it aims to demonstrate the scientific evidence for the need for action to be taken to increase participation in active living and sport, leading to healthier cities and communities. Our research seeks to analyse the city’s natural spaces as scenarios to encourage physical activity and sport, through a combined study of qualitative research techniques: the use of a digital webGIS platform, collaborative maps made by citizens, and surveys conducted with citizens and the local government. This methodology has been tested in the city of Malaga, the European City of Sport 2020. The study of the city’s main sport areas, the waterfront and natural green spaces provided data on the types of physical activity taking place in each of these areas and the physical activity needs of citizens. This research argues that it is important to know the criteria of local communities for physical activity and/or sport in natural environments, as well as the main demands expressed. This will provide valuable information to design and manage natural public spaces as a means of promoting physical activity and healthy habits.
