The early diagnosis in Autism Spectrum Disorder (ASD) is crucial for timely interventions to address the patients’ attentional and social challenges. The currently study aims to use machine learning algorithms to accurately predict ASD outcomes. Dataset from a Kaggle competition was used to perform the prediction analysis. Five supervised machine learning algorithms were employed: Logistic Regression (LR), K-Nearest Neighbors (KNN), Support Vector Machine Classifier (SVC), Random Forest (RF), and Decision Trees (DT). The models were fine-tuned using a range of possible hyperparameters and evaluated using ROC AUC scores. The best-performing model, Random Forest, achieved a training ROC AUC of 0.93. The model's performance in predicting the unseen test set resulted in a ROC AUC score of 0.8623. The outcome demonstrates the potentials of machine learning models in early prediction of ASD symptoms, which provides support for autistic individuals to enhance their quality of life and education.

National image is an important part of China’s “soft power”. The Economist uses a large number of metaphorical frames that relate to all aspects of China’s development. Through these metaphorical frames, The Economist endows reports with its concepts and attitudes towards China, and these metaphorical frames also influence readers in an invisible way. This thesis uses the theory of framing and conceptual metaphor to analyze about 110 economic reports on China in The Economist in 2021. Specifically, three kinds of framing metaphors are discussed. They are war metaphors, sport metaphors, and journey metaphors. By analyzing the national images constructed by metaphors in each frame, the thesis finds that the journal sees China as a rising power, with its rising international status, rapid economic growth, world-leading technology and active participation in global governance, which constructs a positive image of China as a developing and progressive country. However, due to the inherent ideological bias of the West, the report maliciously smears China’s national image, especially in terms of regime and human power. In addition, it also believes that China restricts freedom of speech and its environmental pollution is serious. In conclusion, The Economist has constructed an overall negative national image of China, which has exerted profound international influence. In the context of profound changes in the international communication environment, the author hopes that this thesis can provide some enlightenment for improving China’s international discourse power.

With the increasing interdependence between states, populism also rises through opposing current institutions, which gradually becomes a political force in some regions nowadays. However, there is no accepted academic definition of populism. Therefore, this essay lists three major approaches for scholars to define populism, the sociocultural approach, the political-strategic approach, the ideational approach, and makes some critical comments on them. After the evaluations, the reasons why the ideational approach is the most probable method to illustrate populism can be explained. By analyzing the mobilization of populism in different regions, the core features of populists can be reflected and the demands of populists can update with time advance. On the aspect of political effect, this article studies its influence on democratic institutions and policy-making, which show both positive and negative sides under different circumstances. In summary, populism is a special kind of ideology related to the people and the elite that can attach to other ideologies. Besides, populism can remind the rulers to solve some problems when they are in opposition, nevertheless, populism can also be a threat to democracy when they thoroughly control a regime.

The political practice of populism has long existed in Europe, in recent years, the concept of “populism” has received increasing attention and it has frequently appeared on the political stage in various European countries. “Populism” is especially popular and typical in Italy, while problems also emerge with different forms. What’s more, this ideology always appears as a discourse of two opposing groups. The paper explores the development of populism in Italy, its impact on Italy and Europe as a whole by using a case study of Italian populist political parties and adopting Cas Mudde's definition of populism. As a result, populism could be illustrated as a tool for regulating the European society when there is a democratic imbalance. In the end, we can find the pattern of populism, try to predict its future development and its effects in different spheres in Europe, and then gain some awareness of the predicament of European society.

With Donald Trump's defeat in the presidential election, America's right-wing populist and non-establishment political leader lost his former glory and was replaced by Joe Biden, who supported multiculturalism and the establishment. However, the end of the general election does not mean the end of the conflict and struggle between the four directions of right-wing populism and multiculturalism, non-establishment camp and establishment camp. The opposition in these four directions makes the dilemma of today's American democratic politics clear. The phenomenon of social division and political polarization deserves attention, and the study of the background and impact of the conflict can help analyze the social problems existing in the United States. The struggle between the left and the right and the establishment complexly exists between the two parties, triggering a series of chain reactions such as Hillary's defeat, Trump's political moves and the "Capitol Hill" incident, and further intensifying the intensity of the struggle. Relevant concepts about struggle will be elaborated, the historical factors of struggle will be traced, and its profound and widespread impact on American society will be analyzed.

Despite the increasingly sophisticated management systems in China, food safety issues continue to be a persistent problem. This paper examines the underlying issues behind food safety regulation in China, focusing on the recent surge in incidents. Against the backdrop of a risk society, food safety issues have become a hot topic in Chinese society today. Our research on it should not only be limited to interpreting it as a shallow phenomenon of unscrupulous businessmen profiting at the expense of conscience, nor should it be simply attributed to the negative effects of modern food chemical technology development. Instead, we should start from the perspective of the theory of risk society to gain a more thorough understanding and comprehensive reflection. The backdrop of a risk society in transition, China's food safety problem has become increasingly severe. To better withstand risks and move towards a safer society, it is essential to fully recognize the importance of food safety and establish a scientific and reasonable system of risk governance through improving legal mechanisms, risk communication and interest mechanisms.

Recent empirical evidence has indicated a potential avenue for ameliorating the nutritional status of children in developing nations through focused interventions in the realms of food and agriculture. This research delves into the issue of child stunting prevalence in developing countries, scrutinizing the impact of corruption on the efficacy of such interventions. Utilizing comprehensive data derived from the Organization for Economic Cooperation and Development (OECD) and the World Bank, this study meticulously analyzed evolving trends. Notably, the investigation revealed a diminishing prevalence of child stunting among both genders but the role of total aid emerged as inconsequential in contributing to this positive trend. Furthermore, an intriguing revelation surfaced, indicating that the battle against child malnutrition hinges not solely on the optimized distribution of foreign aid but significantly on the curbing of corruption. The research uncovered a notable improvement in children's nutrition correlated not with the augmentation of foreign aid but with the augmentation of public health expenditures, thereby emphasizing the pivotal role of corruption control. This discernment underscores the imperative need for targeted aid and robust governance mechanisms to effectively combat the formidable challenge of child malnutrition.

People have been bothered by anxiety. Studies have shown that the elderly may feel stressed about future life. Few essays focused on the anxiety of younger generations' worries about future post-retirement life, which is going to be the main focus of the study. The research surveyed 101 samples to obtain information on the anxiety level of youth and the causes. By analyzing these samples, attention should be paid to the anxiety of the younger generation, and it varies from person to person. The main reasons for anxiety were concerns about financial issues, loneliness, and illness. Those reasons show rather a large amount of overlap with the anxiety of the elderly due to similar issues: the fear of being accompanied and the financial issues. Besides, some objective factors contributed to anxiety positively: the number of children and the parent's marital status, while their marital status and the number of siblings hurt the participants' stress levels.

Educational inequality in China has been a long-standing problem, but the COVID-19 pandemic has exacerbated its impact. The sudden outbreak of COVID-19 and its extreme spread have severely impacted education systems, creating new challenges for students and educators. The shift in learning styles from classroom to distance learning and campus closures have exacerbated existing inequalities, highlighting the urgency of addressing this issue to ensure equal access to education for all students in China. By analyzing the disparate impacts of campus closures, distance learning, and access to technology on different socioeconomic statuses and regions and highlighting differences in educational opportunities, this paper explores how the COVID-19 pandemic has exacerbated educational inequalities in China's education system. COVID-19 is exacerbating educational inequality by highlighting disparities in digital access, resource availability, and learning environments, making it harder for disadvantaged groups to access equal educational opportunities.
