In order to deeply understand the status of ideological and political research on experimental courses in colleges and universities,the relevant literature collected by China National Knowledge Infrastructure(CNKI)was taken as the research object,and the analysis was carried out by using CiteSpace software.The results show that research authors of ideological and political education in experimental courses have not yet formed cross-regional cooperation,and there is no core author.The ideological and political construction of experimental courses mainly focuses on experimental courses such as medicine,chemistry,and physics.The research focus on ideological and political education in experimental courses focuses on the concept of educating people,the construction of teaching systems,teaching modes,and the combination of new experimental teaching methods and ideological and political elements.The ideological and political education of experimental courses needs more attention and support from colleges and universities. 展开更多

This study adopts the grounded theory approach to critically examine the essence and implementation of Ideological and Political Education(IPE)within college English curricula at Chinese Universities.We analyzed a corpus of 80 award-winning lesson plans from the“Teaching Star Competition”held by the Foreign Language Teaching and Research Press to establish specific constituents that comprise IPE and identify the instructional methodologies incorporated in the teaching process.The research shows that IPE strategically merges language proficiency training with civic education,aiming to cultivate a strong national identity,solid cultural pride,and global competencies.To be more detailed,the core categories of IPE encapsulate critical thinking,professional ethics,and cross-cultural communication skills,which are based on the innovative use of technological resources and adaptive pedagogical strategies.IPE has also elaborated on the comprehensive assessment mechanisms to measure cognitive and affective outcomes,making it a multidimensional activity.Following a three-stage coding process,this study aims to contribute to this discussion regarding ideological and political education integrated into Chinese higher education institutions.The finding and conclusion in this study drawn for future curriculum developments and reformulation of educational policy suggest ways IPE could better serve in fostering well-rounded individuals capable of contributing to national and global contexts. 展开更多

This paper describes how virtual classrooms and out-of-classroom instruction can be used to help students in ideological and political theory courses strengthen their identities and improve the efficiency of their assignments.By using immersive media technology,the course is turned into a form of entertainment,enriched with content,and combined with methods such as digital video editing and manipulation to meet the needs of students in university ideological and political theory courses.Virtual reality technology can create realistic virtual environments created by computers,enabling students to perceive and manipulate a variety of virtual objects,interact with them,and create a sense of immersion in the virtual environment.Research has shown the potential benefits of using immersive media technologies and augmented reality in education.The potential of virtual reality in education has been increasingly emphasized and has been widely researched and applied. 展开更多

Increasing attention has been focused on the extent to which corporate political connections influence the growing pollution due to the rapid growth in the popularity of firm pollution in developing countries.We adopt a static threshold regression model to investigate the effects of heterogeneous environmental regulation on political connections and firm pollution based on the panel data from China’s A-share listed companies from 2012 to 2019.The empirical results show a non-linear relationship between the degree of political connection of listed company executives and the level of firm pollution.And the relationship between the two roughly presents a U-shaped relationship under the action of the marketincentive environmental regulation threshold.However,it roughly presents an inverted N-shaped relationship under the action of the command-control environmental regulation threshold.Additionally,the group test results show that the existence of regional and ownership heterogeneity causes certain differences in the environmental behaviour of politically connected enterprises.These findings indicate that diverse environmental regulations are needed to promote sustainable green development and to further expand the theoretical and practical exploration of political connections on firm pollution. 展开更多

Opinion Mining(OM)studies in Arabic are limited though it is one of the most extensively-spoken languages worldwide.Though the interest in OM studies in the Arabic language is growing among researchers,it needs a vast number of investigations due to the unique morphological principles of the language.Arabic OM studies experience multiple challenges owing to the poor existence of language sources and Arabic-specific linguistic features.The comparative OM studies in the English language are wide and novel.But,comparative OM studies in the Arabic language are yet to be established and are still in a nascent stage.The unique features of the Arabic language make it essential to expand the studies regarding the Arabic text.It contains unique featuressuchasdiacritics,elongation,inflectionandwordlength.Thecurrent study proposes a Political Optimizer with Probabilistic Neural Network-based Comparative Opinion Mining(POPNN-COM)model for the Arabic text.The proposed POPNN-COM model aims to recognize comparative and non-comparative texts in Arabic in the context of social media.Initially,the POPNN-COM model involves different levels of data pre-processing to transform the input data into a useful format.Then,the pre-processed data is fed into the PNN model for classification and recognition of the data under different class labels.At last,the PO algorithm is employed for fine-tuning the parameters involved in this model to achieve enhanced results.The proposed POPNN-COM model was experimentally validated using two standard datasets,and the outcomes established the promising performance of the proposed POPNN-COM method over other recent approaches. 展开更多
