Authors: Li Junni
Published: December 2024

With the rapid development of artificial intelligence (AI), text generation has become a field of great concern. However, there are few related studies from the perspective of linguistics. Natural language processing technology should have been combined with linguistics, but traditional linguistics cannot provide sufficient theoretical support for large language models. Thus, linguistics is getting farther away from the needs of the times. This paper aims to analyze why the integration of large language models and linguistics is insufficient, with ChatGPT as an example to explain the text characteristics of AI writing and its reasons. In addition, this paper explores the impact of AI-generated text patterns on linguistics and how linguistics will develop in the new era.

The Impact of MOOCs on Traditional Higher Education Systems
Authors: Huang Fangfeifei
Published: December 2024

Since the turn of the twenty-first century, the concept of multiple open and free online teaching courses has steadily increased in popularity. Still the theoretical foundations of these courses predate the digital revolution and may be traced back to the 1960s. The rise of major MOOC carriers like Coursera, Udacity, and edX, along with the participation of prestigious U.S. universities, has offered many free and high-quality online courses since 2007. This led Time magazine to call 2012 the "Year of the MOOC." Researchers globally are analyzing how to promote MOOC development and its future impact on higher education. Students born after 1995 in China, who are increasingly interested in MOOCs, are challenging traditional higher education models. The widespread adoption of MOOCs indicates that China's traditional higher education system may undergo significant changes. MOOCs are defined as online courses designed for unlimited participation and open access via the Internet, including traditional materials and interactive forums. However, uncertainties about MOOCs' future growth and openness have been noted. MOOCs impact traditional higher education concepts by challenging existing philosophies and integrating new teaching methods like flipped classrooms and blended learning. Despite these advancements, traditional education in China faces challenges with outdated MOOC designs and low course completion rates. The study suggests that MOOCs can drive substantial reforms in Chinese higher education, such as updating traditional concepts and enhancing teaching methods. Future research should focus on quantitative evaluations of MOOCs' impacts and incorporate international experiences to advance higher education reforms in China.

Authors: Sun Siyang
Published: December 2024

There has been extensive research on the impact of subtitles on incidental vocabulary acquisition (IVA) in video watching, but investigation on the influence of relative font size and position sequence of bilingual subtitles on IVA outcomes is scarce. Additionally, we examined the effect of video genres on vocabulary acquisition and the moderating roles of participants' existing vocabulary knowledge and English proficiency. Eighty Chinese-speaking college EFL learners participated in this study to measure the effects of viewing two videos on form recognition and meaning recognition. The findings revealed that E/C Same Size (English above, Chinese below, same size) lead to higher scores than C/E Smaller C (Chinese above, English below, Chinese smaller) in the word meaning recognition test. However, no significant differences were found in vocabulary acquisition between comedy and edutainment. However, participants' vocabulary size moderated the effect of subtitle format on word meaning learning, indicating that existing vocabulary knowledge plays a role in how learners benefit from different subtitle formats.

Authors: Chen Shiyi , Yuan Zijun
Published: December 2024

Anxiety disorders are among the most prevalent mental illnesses, particularly among adolescents. Those adolescents experience chronic, persistent, excessive, and uncontrollable worry, as well as irrational fears, across various aspects of daily life. Despite the high incidence, only about 25% of affected individuals receive treatment, and among those, only approximately half achieve recovery with existing therapies. This study investigates biomarkers of anxiety disorders among adolescents using multimodal MRI data. The findings reveal structural and functional biomarkers, including changes in cortical area, thickness, and volume and alterations in functional connectivity and structural covariance network indices based on graph theory. Including a broad range of participants from the Adolescent Brain Cognitive Development (ABCD) Study, with diagnoses made through the Child Behavior Checklist (CBCL) scores, the research applies the linear mix model to partial out the covariates. The results show that adolescents with anxiety disorder exhibit abnormality in cortical structure, functional connectivity, and structural covariance among brain regions. The discussion contextualizes these findings about the behavioural symptoms associated with adolescent anxiety disorders.
Challenging Contemporary Understandings of the Industrial Revolution
Authors: Xiang Weiqing
Published: December 2024

This article challenges the traditional view that the Industrial Revolution drove sustained economic growth globally and re-evaluates the impact of this important historical period from a non-Western perspective. The article points out that while the Industrial Revolution is often seen as a turning point for global economic prosperity, non-Western countries struggled with the aggression, colonization, and exploitation of Western imperialism during industrialization. Meanwhile, there were also problems of worsening economic inequality and social instability within Western countries. Furthermore, the article emphasizes the concept of "creative destruction", noting that the Industrial Revolution created new economic structures and opportunities while destroying traditional systems and causing profound social and economic changes. Therefore, the author argues that viewing the Industrial Revolution as a mere catalyst for global economic growth is a too simplistic understanding, neglecting its complexity and diversit.
Analysis of the Origin, Examination of the Predicament and Improvement of the Efficacy of Emergency Volunteer Activities from the Perspective of Disaster Politics
Authors: Jiang Huizhong , Ren Qingyuan
Published: December 2024

Disaster politics is the science that studies how the state uses the power of political power to carry out response activities such as prevention and emergency preparedness, monitoring and early warning, emergency response and rescue, and post-event recovery and reconstruction of various major disasters. As the earliest self-help and mutual rescue behavior taken by human beings to fight against disasters, the interactive relationship between emergency volunteer activities and national rescue activities originated from the tension between man and nature and between people, and gradually became an important symbol of social civilization and progress under the role of culture. However, in recent years, emergency volunteer activities have faced many difficulties in the process of interacting with the state, such as insufficient ability to obtain resources, lack of rule of law, lack of digital platforms, lack of coordination and action mechanisms, uneven professional capabilities, and insufficient incentives and guarantees. To solve many problems in the whole process of disaster co-governance, it is necessary to continuously strengthen education and guidance, promote the connection between supply and demand, strengthen the role of the rule of law, promote social co-governance, build a "peacetime and emergency" system, establish an on-site command mechanism and an effective coordination mechanism, and improve the evaluation standards and incentive and guarantee systems, so as to continuously improve the effectiveness of emergency volunteer activities at a time when disasters tend to be extreme and frequent.

Authors: Liu Yanghe , Xu Yuting , Liu Zhan
Published: December 2024

The recommendation of new media short videos plays a crucial role in today's social media and content consumption. Short videos can rapidly disseminate information, capture users' attention, and quickly accumulate a large audience. According to the latest data, as of April 2024, TikTok, a globally renowned short video social media platform, has been downloaded over 4.92 billion times worldwide, with more than 1.582 billion monthly active users. However, the recommendation algorithms of current mainstream social platforms often favor content that generates a large amount of interaction in the short term, which may negatively impact the dissemination of content with long-term value and depth. To address this challenge, this paper proposes a knowledge graph-based recommendation method for new media short videos, which structures the representation of short video content by associating it with related concepts, entities (such as people, places, events, etc.), and their relationships, thereby providing a more accurate understanding of the video content’s semantics. This paper delves into key technologies including knowledge graph construction, user interest modeling, short video content modeling, semantic matching, and recommendation. Through practical application cases and comparative experiments, the effectiveness of this method is evaluated. The results show that the application of knowledge graphs in short video recommendation can significantly improve the quality of content recommendations, offering users a richer and more personalized viewing experience.

The rapid detection of radioactive elements in nuclear sewage in seawater is of great significance to the marine ecological environment and human life and health. At this stage, the water quality testing process is complex, the detection cycle is long and the cost is high, which cannot meet the needs of real-time monitoring of marine nuclear polluted water quality. In this paper, a highly sensitive terahertz detection chip (Multi-torque double-ring mutual coupling chip) was designed based on the terahertz wave with strong absorption of polar molecules, and the terahertz spectrum was obtained by simulating and testing different sewage samples, and the spectral differences between the same sample and different samples were studied. The experimental data show that the outer ring and the inner ring have the same direction of surface current and similar electric field intensity distribution, and can play a great role in mutual superposition and enhancement effect when resonant, the transmission characteristics can reach -54dB, and the figure of merit can reach 447. Moreover, the spectrum recognition of different seawater pollution samples is good, and the nuclear sewage and purified water samples can be clearly distinguished. On this basis, the chip structure, material selection, refractive index design and related parameter simulation are further optimized, which provides a new detection technology and idea for marine quality monitoring, which can be widely used in the real-time monitoring of marine nuclear pollution water quality and the high-sensitivity identification of other water-soluble liquids, which is of great significance to marine ecological environmental protection, industrial sewage treatment monitoring and other fields.

Published: December 2024

Salt stress seriously affects grape yield and quality and has become one of the major abiotic stresses that constrain the development of the grape industry. In the actual research process, it is difficult and time costing to obtain transgenic grape seedlings through genetic transformation system. Therefore, the establishment of a rapid identification system of salt tolerance in grapes using callus as materials is necessary to identify the function of genes in salt stress response. In the present study, different concentrations of NaCl were applied to embryogenic and non-embryogenic callus tissues, and salt tolerance indexes were measured. The results were analyzed to determine the best indexes to characterize the salt tolerance of different grapevine callus, which would lay the foundation for the rapid identification of salt tolerance genes in grapes. The growth status was observed after 28 days and parameters such as growth (in dishes), MDA content, free proline content and relative electrical conductivity were determined. It was ultimately found that electrical conductivity increased more in merlot and shiraz than in other salt tolerance indicators and was the most sensitive to changes in salt stress, so it was determined that electrical conductivity could be used tomonitor changes in salt tolerance in grapevine callus tissues.

Published: December 2024

In the era of big data, the decision-making environment has undergone profound changes, and traditional decision-making methods cannot be applied to large-scale group decision-making (LGDM) problems. For urban transportation schemes, a managing consensus process in LGDM with self-confident double hierarchy interval hesitant fuzzy linguistic term set (SC-DHIHFLTS) is proposed. Firstly, based on the double hierarchy hesitant fuzzy language (DHHFL), the concept of SC-DHIHFLTS is proposed. The basic elements are composed of double hierarchy interval hesitant fuzzy set and self-confidence degree. Secondly, based on the SC-DHIHFLTS, a managing consensus process method in urban transportation schemes is developed, including expert distance measurement, qualitative and quantitative weight determination method, consensus model and adjustment mechanism, and intelligent decision-making is carried out by computer. Finally, the proposed LGDM consensus method is applied to a practical transportation scheme decision-making problem, and the effectiveness is verified by comparative analysis with existing methods.

Results After teaching, the total score of the observation group's learning achievement was 161.01±3.17, the total score of nursing students' humanistic caring ability was (200.13±2.13), and the score of the objective structured clinical examination OSCE examination was (96.68±3.17), which were higher than those of the control group. The differences were statistically significant. Conclusion Compared with the traditional teaching method, the situational simulation teaching method can effectively improve students' academic performance, clinical examination OSCE examination scores and enhance nursing students' humanistic care ability.
Prediction of waste separation behavior and its underlying mechanisms using logistic regression
Authors: Zhang Xuejin , Liu Pingping
Published: December 2024

Waste separation is essential to reduce the impact of pollution on the environment and to promote sustainability. Despite the implementation of waste separation policies in many countries and regions, the results have not met expectations. Therefore, it is imperative to identify the key factors that encourage waste separation behavior. Based on self-determination theory and the theory of planned behavior, we examine these determinants and underlying mechanisms of green intrinsic motivation and perceived factors on waste separation behavior. The study employs logistic regression to identify predictor variables, and uses the Python statsmodels library for data analysis. The results show that green intrinsic motivation and perceived control positively predict waste separation behavior, while perceived difficulty has a negative predictive effect. Perceived control mediates the effect of green intrinsic motivation and perceived difficulty on separation behavior.

Published: December 2024

Surface defect detection based on machine vision is more and more widely used in the industrial field. However, the noise in the image is inevitable, and the quality of filtering and denoising has a decisive impact on the success rate of subsequent defect recognition. This paper summarizes the causes and types of noise in machine vision images. This paper introduces three kinds of noise in detail, including Gaussian noise, Poisson noise and salt and pepper noise. The generation mechanism of the above three kinds of noise is analyzed and displayed in the detection image of electric vehicle magnetic tile components, and the characteristics of the noise are compared in the form of three-dimensional diagram. Finally, the common denoising methods are introduced.

Published: December 2024

In the vast universe, Mercury being the closest planet to the sun, has garnered significant attention from scientists due to its unique precession phenomenon. The precession of Mercury is the manifestation of law of Mercury's space motion. Through the study of Mercury's precession, it can promote the understanding of the subtle changes of the Mercury's orbit and position, and also provide reference for the study of other celestial bodies. In this study, the mystery of Mercury's precession will be deeply discussed. First, the basic concept of Mercury's precession and the research progress made by scholars will be expounded. Then, from the perspective of modern theory, the theoretical explanation and aerodynamic mechanism of Mercury's precession will be expounded in detail under the framework of the centrifugal force theory. And on the basis of these theoretical knowledge, this article analyzed the principle of Mercury precession from the aspect of concrete manifestation and physical mechanism, to uncover the science behind it and enlighten the understanding of the laws of planetary motion, and then to speculate the evolution history and future trend of the solar system.

In order to solve the problem of poor lubrication effect of water seal in large gate, three kinds of nozzles with different structures are designed. In order to further explore the best installation form of nozzle, the water flow animation of 3# nozzle at different angles, different installation positions and different water pressures was simulated by using Blender and ANSYS-CFD, the best lubrication effect is obtained when the distance from water seal section is 40mm and the water pressure is 0.5MPa. The experimental results show that the model test results of 3# nozzle are basically consistent with the simulation results, and the optimum 3# nozzle has the best lubrication effect. The research results can provide technical reference for the optimization transformation of water seal lubrication and the design of water seal lubrication for the same type of gate.
