Efficiency and regional divergence in China’s poverty reduction (SDG 1) and decent work and economic growth (SDG 8)
No full textAddressing regional disparities while pursuing sustainable development has become a critical policy challenge. This study develops a meta parallel two-stage dynamic range directional measure (RDM) directional distance function (DDF) data envelopment analysis (DEA) model to evaluate the efficiency of poverty reduction (SDG 1) and decent work and economic growth (SDG 8) across 30 provinces in China. Given uneven regional development, the provinces are grouped into eastern, central, and western regions, and kernel density estimation is employed to examine the spatial and temporal evolution of efficiency. The results indicate that: (1) The overall efficiency is moderate, with an average score of 0.67, highest in the eastern region, followed by the western, and lowest in the central region. (2) The efficiency of SDG 8 (0.93) significantly exceeds that of SDG 1 (0.87), while the regional ranking remains consistent with the overall efficiency. (3) The technology gap among the three regions shows dynamic changes: the western region has overtaken the eastern region to become the most advanced. In contrast, the central region continues to lag, and its gap with the other regions is steadily widening.

University students’ perspectives on creativity in learning in the 21st century
No full textThe importance of students’ creativity in tertiary institutions lies in the need to prepare young people for the 21st century. On the other hand, higher education is generally unfamiliar with creativity environments, so it will hinder their learning creativity outcomes and experiences, which will impact their creativity cognition and knowledge. The research goals are to calculate the percentages of university students’ perspectives on the importance of their learning creativity outcomes and experiences and to test the influence of each variable. All respondents are 586, with an age range of 19–24 years. The author created learning creativity instruments. The results showed that there are twelve outcomes and eleven experiences of learning creativity that are important to university students. Less than 50% of university students get learning creativity experiences on campus four or more times a week and/or for more than three hours a day. There is a positive and significant influence between the importance of learning creativity outcomes and experiences as well as the frequency and duration of those experiences. For achieving twelve learning creativity outcomes, tertiary institutions must ensure the implementation of experiences learning creativity experiences, as well as the adequacy of the frequency and duration of those experiences
Challenging human creativity: an exercise of co-creation with generative artificial intelligence
No full textThis paper explores the collaborative potential between humans and generative artificial intelligence in creative contexts through a co-creation framework. The study uses ChatGPT to develop narrative elements such as slogans, taglines, and claims for university marketing programs, comparing human-generated and artificial intelligence-generated content to evaluate effectiveness and engagement. Results indicate that while artificial intelligence can contribute useful and creative content, human participants still prefer human-generated narratives in many instances. The study also highlights how generative artificial intelligence can enhance creative processes by accelerating ideation and reducing cognitive load, but it raises concerns regarding the originality and diversity of artificial intelligence-generated content. This research provides insights into the integration of artificial intelligence in collaborative creative work and suggests best practices for leveraging artificial intelligence tools in marketing and communication strategies
Dynamic effect of sports parks on housing prices: Evidence from Hangzhou Asian Games Park
No full textThe construction of sports parks often involves significant investment and extended development timelines, making it crucial to evaluate their economic impacts for informed policymaking and strategic urban planning. While research on the externalities of urban parks has grown, the specific economic effects of sports parks remain underexplored. This study examines the impact of the Hangzhou Asian Games Park on housing prices using 31,329 transaction records from 2018 to 2023. Employing a hedonic pricing model and a difference-in-differences approach, we find that housing prices increase by 1.6% for every 1 km reduction in distance to the park. Spatial heterogeneity is observable, as the effect diminishes with increasing distance. Temporally, the park’s planning announcement triggered a 0.7% increase in price-distance elasticity, compared to a 0.2% increase after its opening. These findings suggest that the anticipatory market response was stronger than the realized benefits after the park’s completion. This study quantifies the spatial and temporal dynamics of the economic value of sports parks, providing valuable insights for urban planning, public policy, and investment strategies
Structurally informed architectural designs defined by Catalan surfaces – examples of study projects
No full textIn the case of effective structural forms, characterized by a close symbiosis of architectural form and fabric solution, the properties of geometry not only enable the realization of the intention, but remain the main medium of shaping architectural expression in the aesthetic dimension. Moreover, geometric topological forms described by parametric equations provide many opportunities to model structures, also in digital spaces. Paying attention to these aspects was the goal of the academic design task specified in this paper
Study on suitability assessment method of vegetation restoration species in disturbed sites of transmission line engineering construction
No full textScreening species that can adapt to the disturbed habitats resulting from transmission line construction is of great practical significance for the ecological restoration of primary vegetation degradation caused by such construction. Therefore, a suitability evaluation method for vegetation restoration species in disturbed areas of transmission line engineering construction is studied to improve the ecological restoration. Based on the principles of stability and durability, adapting to local conditions and trees, and comprehensive and dominant screening, an index system for evaluating the adaptability of vegetation restoration species is established. Determine the subjective weight of evaluation index by G1 method and G2 method. The objective weight of evaluation index is determined by improving entropy weight method and deviation method. Through the optimal combination weighting method, the final evaluation index weight is obtained by combining subjective weight and objective weight. Using cloud model combined with index weight to calculate the certainty of each index. According to the principle of maximum certainty, the evaluation grade corresponding to the maximum certainty is selected as the final suitability evaluation result. The experiments have demonstrated that the suitability evaluation index system of this method exhibits high reliability, and it can effectively determine the weights of the suitability evaluation indices and complete the suitability assessment for vegetation restoration species. Among these species, Elymus chinensis, Panicum miliaceum, Brassica napus, arugula, and rye exhibit the most promising ecological restoration effects
Research on the composting of dog hair waste
No full textWaste management is one of the most important environmental areas for protecting the environment and human health. Biowaste decomposes and releases pollutants into the environment if left unmanaged or improperly managed. With the increasing demand for pet (especially dog) hairdressing all over the world, it is natural that the amount of discarded waste from animal fur care is also increasing. Dog hair waste can be used for the production of yarns and insulation materials, for the production of filters, and for co-posting. Composting of dog hair was chosen for the study because of its high nitrogen content and because it is one of the simplest ways to use dog hair waste. The main parameters of the composting process are analysed in the paper: C, N, ratio, pH, temperature, moisture content and electrical conductivity measurements.
