Investing in stocks has been very popular in recent years. Investors hope to make a profit by investing in stocks. However, stock prices are highly volatile. Many investors judge whether to invest in stocks based on historical stock prices, technical indicators and market conditions. There are many researches about stock price forecasting in the research field but seldom for cash dividend. The profitable methods of investing in stocks include earning the stock spread and the cash dividends that the company distributes to shareholders. However, cash dividends are major profit for the long-term investor. In this research, we proposed a Stacked Long Short-Term Memory model to predict the value of the company's annual distribution of cash dividends that provided a basis for managers and investors to make investment decisions. The experiments showed the accuracy of prediction for Cash Dividend of the Formosa Plastics Corporation is excellent that the MAPE is only 2.95%.

Global inequality has been a major concern of economists from different nations for the past decades. Fortunately, the economic development has resulted in a decreasing trend of global inequality. For globalization being the foundation of the economic environment, the relationship between the increase of globalization and the decrease in global inequality should be researched so that a method to diminish global poverty could be possibly raised. During the research process, the data of the GDP of different countries was firstly gathered and filtered. Unusual numbers were examined and removed from the data collection based on the research of secondary information and logical deduction. Because there were many variables affecting the result, trade liberalization was selected to be the controlled variable, for its dominant influence on a country's GDP. Taking S-S theory, H-O theory, Neoclassical Economic Growth theory, Endogenous Economic Growth theory, Outsourcing Model and the NEG method, a regression model was generated from the data collection, reflecting the relationship between global inequality and globalization. Using these models, not only the relationship between global inequality and globalization was developed (global inequality decreases while globalization increases), but the exact coefficient of the relationship function. From this research, the importance of trade liberalization to a country's GDP was mathematically reflected, the relationship between global inequality and globalization was found, and the regression model for this trend was established. The result of this research could be used in the process of predicting a country's future economic development and the trend of global inequality.

Live streaming has become a core service developed by social media platforms. Video game live streaming (VGLS)—streamers use live streaming to broadcast their real-time game playing—has been regarded as one of the most innovative business models. However, how game streamers can obtain a stable income source by attracting viewers’ intention to subscribe to their VGLS channels is still unclear. Based on the Social Support Theory and subjective well-being (SWB) perspective, this research proposed that compared to non-live streaming videos, real-time interaction between streamers and viewers during broadcasting is VGLS platforms’ core feature, which might enhance viewers’ perceptions of social support and SWB. Drawing on Theory of Reasoned Action, the aim of this study is to explore the influences of social support and SWB on viewers’ intention to subscribe to VGLS. The results showed that viewers could perceive the informational, emotional, and instrumental supports through the received information provided by streamers and the real-time interaction with streamers, which further improves viewers’ SWB. In addition, the results found that SWB is an essential mediator in the relationships between the three types of social supports and the VGLS attitude. The result also revealed that the VGLS attitude and SWB could enhance the VGLS subscription intention. This research highlighted the vital roles of social supports and SWB in boosting the VGLS subscription intention. Finally, this research provided suggestions for streamers to conduct live streaming and social media platforms to manage the broadcast services.

Analyzing students' classroom behavior is an important part of evaluating classroom teaching effects in the education field, and the behavior of using mobile phones is an important manifestation of students' learning status. Therefore, the status of using mobile phones in the classroom can reflect the effect of classroom teaching to a certain extent. This article establishes a video-based classroom student behavior data set, and divides the behavior categories in the data into two categories: mobile phone playing and other; analysis of students playing mobile phone and other behaviors reveals that there are subtle movements in student behavior and a certain visual tempo. The resolution is low, and the occlusion is serious. In response to the above problems, this paper proposes a multi-scale mobile phone playing behavior recognition method based on temporal information enhancement and interaction. First, use the motion enhancement module to enhance the motion information between two frames to improve the recognition ability of subtle actions; secondly, add the temporal pyramid to extract the multi-scale features of the action, and then obtain the visual tempo information of the video; finally add the temporal information interaction module to enhance the temporal dimension information interaction , To further model the temporal information. The experimental results on the self-made student action dataset StudentAction show that compared with the existing methods, the algorithm has significantly improved recognition accuracy and better solves the problem of low accuracy in the recognition of subtle actions. Good performance have shown on the public datasets HMDB51 and UCF101, indicating that the method has strong generalization ability and can adapt to the recognition problems of different scene actions.
