The students enrolled in the class chose to study the theme Brazilian Public Politics. After several debates regarding the theme, the students were separated into three groups and each group chose a subtheme to study. The themes were IDH （index of human development）, minimum wage and social security. As an example, a description of the thematic project about the minimum wage in Brazil is presented. The principal results obtained in the study of this theme include a discussion about the potentialities of the theme as a classroom activity in different levels of schooling. As an educational activity, the thematic project demonstrated itself to be greatly relevant, since not only did it provide the learning possibility of mathematics related to the issues studied, but also promoted various discussions regarding the theme, which, in our conception, contributes to the social-critical development of the students. Finally, from the point of view of applied mathematics and mathematics education, the development of a modelling activity from thematic projects showed itself to be a good source of researches.展开更多

The model was verified by the comparison of computed results and measured data from 1986 to 1996. Num erical prediction of the erosion and deposition downstream of the Xiaolangdi Res ervoir in its first operation year was carried out, and a series of suggestions were given for reservoir operation mode in its early operation period.展开更多

文摘In this paper, the authors present a modelling activity developed from a thematic project in the models and mathematical modelling class of the professional master＇s degree program in mathematics education at the Federal University of Ouro Preto. The students enrolled in the class chose to study the theme Brazilian Public Politics. After several debates regarding the theme, the students were separated into three groups and each group chose a subtheme to study. The themes were IDH （index of human development）, minimum wage and social security. As an example, a description of the thematic project about the minimum wage in Brazil is presented. The principal results obtained in the study of this theme include a discussion about the potentialities of the theme as a classroom activity in different levels of schooling. As an educational activity, the thematic project demonstrated itself to be greatly relevant, since not only did it provide the learning possibility of mathematics related to the issues studied, but also promoted various discussions regarding the theme, which, in our conception, contributes to the social-critical development of the students. Finally, from the point of view of applied mathematics and mathematics education, the development of a modelling activity from thematic projects showed itself to be a good source of researches.

文摘Purpose:With the deep integration of information technologies into urban governance,smart communities have emerged as pivotal platforms for advancing sustainable urban development.However,existing research has not offered a systematic analysis or clear presentation of the field’s academic evolution and thematic structure.This study examines the literature on smart communities published between 2000 and 2024.Employing data analysis and visualization tools,it aims to trace the evolution and development trends of smart community research,map its core themes and their interrelationships,and provide actionable insights for policymaking and practical implementation.Design/methodology/approach:Based on 2,347 publications indexed in the Web of Science from 2000 to 2024,this study employed CiteSpace and VOSviewer to conduct co-citation analysis,keyword co-occurrence mapping,national collaboration network analysis,author and institutional contribution assessment,burst detection,and hotspot term analysis.The literature screening adhered to predefined publication-type criteria and citation-count thresholds to ensure that the results were representative and reliable.Findings:This study,through literature analysis and data visualization in the field of smart communities,yields the following principal conclusions.First,the application of digital twin technology in optimizing smart community resources has attracted growing attention,demonstrating considerable potential in urban management,infrastructure maintenance,and resident services.Second,as technology advances,digitaltwin applications are evolving towards greater precision and efficiency,particularly by deepening their support for resource allocation and decision-making processes.Finally,the future development of smart communities will increasingly depend on the deep integration of digital twins with other cutting-edge technologies,thereby driving intelligent management and optimization of community resources.Research limitations:This literature repository excludes grey literature and non-English publications,potentially underestimating the representativeness of grassroots innovation.Furthermore,the temporal analysis was constrained by the citation-lag effects of publications from 2000 to 2024.Practical implications:This study proposes a decision-support toolkit tailored for municipal planners and policymakers.The toolkit comprises three core intervention strategies:multiscale environmental sensing,participatory governance protocols,and regenerative technology pathways.These measures are designed to advance the implementation of the United Nations Sustainable Development Goal 11:Sustainable Cities and Communities.Originality/value:By explicitly defining and applying the“thematic knowledge framework,”this paper offers a concise roadmap for the evolution of smart community research.It also provides precise guidance for designing and implementing community development strategies that align with Sustainable Development Goals.
文摘This article explores the styles and characteristics of thematic art creation in Hong Kong,Macao,and Taiwan regions,analyzing the uniqueness of these regions’artistic backgrounds,artistic languages,theme selections,and expressive techniques.The art creation in Hong Kong,Macao,and Taiwan regions is deeply influenced by traditional Chinese culture while incorporating Western artistic elements,exhibiting a diversified artistic style.Thematic art creation in these three regions has its own distinct features,including a deep exploration of local culture and a sensitive capture of the spirit of the times,which together constitute a rich and colorful artistic landscape in Hong Kong,Macao,and Taiwan regions.
