The Influence of the Online Persona on University Students
Authors: Wang Ziyin
Published: May 2023

The media network constantly updates the cognition of university students. The university students in the media society are gradually symbolized, labeled and fragmented. The network persona further develops and evolves into an idealized role for university students to participate in the media society. Although the concept of online persona has made a lot of research in communication science, the online persona as a symbolic representation of media society still leaves a gap at the psychological level. This paper adopts the questionnaire method to study the positive and negative effects of online personas on the psychology of university students. Through the study, it is found that online personas play a certain role in guiding the psychological development of university students. They also distort their values to a certain extent and cause mental stress and psychological anxiety among university students. Due to the complexity of social information and the immaturity of college students themselves, online persona is also one of the reasons for the confusion between the "true self" and the "ideal self" of college students. Therefore, this paper explores the influence of online personas and suggests that university students should improve their self-cultivation, identify social information and establish correct values.
A Review of Pre-university English Language Education Policies in China 2011-2022
Authors: Qu Kunyang
Published: May 2023

Chinese foreign language education policies (FLEPs) are changing during years of development in aspects of national planning, education, and policy formulation. And the most widely acknowledged foreign language in China is English. This paper critically reviews English language education planning (ELEP) in China under the historical context from 2011 to 2022. The ELEP developments are related to the modern era's economic, ideological, and political changes. At the institutional level, English is considered without controversy as a universal language that promotes national development and offers personal opportunity. However, the English-as-threat notion has been repetitively mentioned in the history of policy development. Examining the political alterations shows that even with doubts and concerns, providing pre-university students with English language education is inevitably strategic. And from reviewing a series of officially published documents and relevant research reports, this study ends with the implications for both English learners and educators in China. As the instrumental role of English has remained essentially unchanged, the concept that teaching language with its culture should be emphasized and encouraged in relation to English teaching and learning standards. Learning English is not only about learning a foreign language, it also involves learning a fresh way of thinking.
Influencing Factors and Countermeasures of Chinese Students' Oral English Proficiency
Authors: Wang Ruizhi
Published: May 2023

With China going global, oral English proficiency seems to be required in more scenarios such as chasing further education in English-medium countries and posts in transnational corporations. However, China’s existing English education probably fails to satisfy the rising need for proficient oral English, where written English tends to be paid much more attention rather than oral English. Despite oral English has been increasingly concerned by the continuous curriculum reform in China, the actual level of Chinese students’ oral English tends to be relatively low. Meanwhile, Chinese students are facing a range of challenges or difficulties in oral English learning. This paper is intended to search for certain approaches to lead Chinese students to overcome these challenges and attain a higher level of oral English proficiency. For this purpose, this paper will systematically review the prior studies. By analysing the results and findings of these researches, the common challenges faced by Chinese students in English learning have been summarised, which are dumb English, the insufficient level of professional quality of English teachers and the neglect of oral English. Moreover, the potential influencing factors aggravating the challenges have also been extracted, that is, foreign language anxiety, educational resources and the education system. Based on the challenges and influential factors, several recommendations have been provided, namely, teaching strategies applied in English classrooms, supporting more education funds and boosting the curriculum reform.
Analysis of Second Language Writing Based on Discourse Coherence Theory- A Case Study of High School Students in A Chinese International School
Authors: Mei Yelin
Published: May 2023

Students’ discourse coherence has always been a topic that is often discussed in writing. For intermediate-level students with the purpose of taking exams, discourse coherence is also an important part of writing. Based on the students’ discourse analysis, this paper obtains the frequency of students’ use in the second language writing process, and uses the form of interviews to study the thinking of students’ writing process. The results of the study found that students at the intermediate level use reference and conjunction much more than the other methods, as others students at the advanced level. However, substitution and ellipsis devices are almost missing in their writing. Such results may be influenced by the test-oriented writing teaching mode in the second language writing class, which will increase the huge difference and partial loss between the different methods used by students. Therefore, in second-language writing teaching for intermediate-level students, teachers can modify the classroom according to the current problems of students.

Analyse on Second Language Learners Learn English Without Native Language: A Case Study of Chinese Learners
Authors: Li Maizi
Published: May 2023

Second language acquisition is a common phenomenon around the world. People around the world started to learn English after it became the universal language. Language transfer occurs between the target language and the mother tongue. In order to reduce the negative transfer between the different languages, the argument of how to deal with native language and target language is an intense discussion among linguistics. This paper focused on the relationship between the native language and target language among different ages, with a case study of Chinese learners who study English as a second language. The research was done by questionnaire and collected 126 responses. After collecting and analyse the data through chi-square, the result shows that there is no strong evidence to prove there has a significant relationship between language transfer with the different ages. But it shows an interesting point that it is necessary to promote the target language environment and mindset among the different ages no matter what motivation persuades the learners to study English.

Research on Influences of the Demographic Organizational Culture on Innovation in Businesses Enterprises
Authors: Li Sirui
Published: May 2023

The COVID-19 pandemic has brought about a significant shift in work culture, with remote and flexible hours becoming increasingly popular. This change has highlighted the importance of work-life balance and resulted in a shift towards democracy in the workplace. In this environment, employees are encouraged to express their opinions and ideas, and managers actively listen to and consider them in their decision-making process. This approach leads to increased innovation as diverse perspectives and ideas are considered. Integrating demographic business models into organizational culture can further promote this democratic approach, as it encourages managers to take into account the unique needs and values of different demographic groups. This leads to a more inclusive work environment, which increases productivity and employee satisfaction. But democratic strategies have potential drawbacks. It may not be necessary for certain types of business, and conflicts may arise as different opinions are expressed. Therefore, businesses must conduct thorough research to determine which democratic strategies are most effective in their particular circumstances. Overall, integrating democratic strategies into organizational culture can be a valuable tool for innovation and productivity. However, balancing this with efficient decision-making and smooth operations is essential.

The Influence of Implicit Guarantee on the Yield Spread of China’s Quasi-municipal Bond
Authors: Xie Mingyan
Published: May 2023

Local government debts are an important part of the bond market. This paper mainly investigates the risk that the implicit guarantee brings to the market of quasi-municipal bonds. The implicit guarantee comes from local government financing vehicles (LGFVs), which are the finance entities for the local government, issue quasi-municipal bonds. Because people are potentially thought these bonds are guaranteed by the local government, the funding cost of quasi-municipal bonds is lower than other bonds. However, some local government's ability to pay back the investors' money is weak which causes some high-rated quasi-municipal bonds to default and triggers many defaults, which, along with the local government's mounting debt, may make investors more concerned about its capacity to repay the loan in the event of default. Therefore, China's central government then issues some policies to reduce the effectiveness of implicit government guarantees, trying to make the quasi-municipal bonds turn to become more marketize and contain less guarantee. In this paper, the author initially tries to demonstrate that the implicit guarantee reduces the yield spread of quasi-municipal bonds. Then, the author argues that the issue of relevant policies lessens the implicit guarantee and increases the marketability of quasi-municipal corporate bonds. Lastly, the author tries to show that different administrative levels of LGFVs will affect the yield spread of the bond.
Research on Quantitative Trading Strategies Based on the Turtle Trading Rule
Authors: Liu Jiaxin
Published: May 2023

Quantitative investment is a newer investment method than traditional investment methods, with features such as being free from emotions and being able to access and process large amounts of data quickly. Based on this, this paper selects fuel oil, FU2205, as the underlying for the period from May 31, 2021 to November 30, 2021 to investigate the effectiveness of the turtle trading rule in quantitative trading strategies. In this way, the effectiveness of the turtle trading rule is explored. The article first introduces the background and significance of the study, explains the current research status of several scholars on quantitative investment and the relevant theoretical background, and then conducts relevant tests on the turtle strategy in three parts. In the first part, the principles of the turtle trading strategy are reviewed, and three important steps are introduced: market entry, position addition and exit. In the second part, the turtle trading strategy is modeled, and fuel oil from the commodity futures market is selected as the sample for backtesting from May 31, 2021 to November 30, 2021. Not only does it far exceed the buy-and-hold return, the Sharpe ratio and maximum retracement are also better. Finally, after tuning the parameters of the strategy and increasing the risk ratio of the account, the total return is significantly improved, but since it is impossible to predict whether the strategy will be profitable or not, this suggests that we cannot increase the risk ratio of the account indefinitely and need to keep it in an appropriate range. The article concludes with a further summary of the study findings and provides an outlook.

Authors: Chen Junjie
Published: May 2023

As an industry sensitive to changes in external factors, the airline industry has been affected negatively by the Covid-19 outbreak. Global travel restrictions sent shock waves throughout the industry, and Air New Zealand is no exception. This study investigates the impact of Covid-19 on the profitability and liquidity of Air New Zealand and the whole airline industry based on financial ratio and regression analysis. The profitability and liquidity are represented by Operating Return on Assets (OROA) and Quick Ratio. Twenty commercial airlines from around the world were chosen as samples to examine how Covid-19 affected the overall airline industry's profitability and liquidity. This study compares the effects of Covid-19 on their profitability and liquidity in an effort to identify commonalities and variances. The study results show that both liquidity of Air New Zealand and the whole airline industry received a significant and positive impact from the Covid-19 pandemic due to the airline's private remediation measures and government interventions. In addition, the study found that the profitability of Air New Zealand was not received significant and negative impact by the Covid-19 pandemic like the whole airline industry due to the cargo schemes supported by New Zealand and Australia. This study is helpful for airlines and the government to formulate remediation measures and policies to facilitate the recovery of the airline industry. Finally, this study recommended that governments can place orders to airlines to support the recovery of the airline industry. And each airline can diversify its sources of profitability to mitigate the negative impact of Covid-19.
Ridesharing Price Prediction: Exploring the strategies of Dynamic Pricing
Authors: Huang Haolun
Published: May 2023

This paper explores the application of dynamic pricing algorithms in rideshare industries and examines the key variables that influence trip prices by analyzing Uber and Lyft Dataset of Boston in 2018. This dataset contains Uber and Lyft data mainly from November and December 2018. It contains essential variables such like distance and price for rideshare price prediction, together with many other variables which could be included in regression model such as weather and hours in the day. The Ordinary Least Square regression method is used in this paper, and results shows that the most influential and statistically significant variables on price are the distance of trip and surge multiplier which indicates traffic surge. The regression result is in accordance with the intuition that price is positively correlated with distance and price goes up during surge time. The result implies that the dynamic pricing algorithm that adjusts live prices heavily relies on the current traffic condition and distance of the trip, while the price is not determined by hour of the trip during the day and temperature.

We hitch go wool-gathering an uncourteous store in a hurry relative to a significant increase in productive activity. We anticipate contract hegemony for nonlinear emphatic vaccines, with insignificant remunerative profits increasing as vaccination rates rise. If absolute containment products are in place or if the country is experiencing a severe outbreak, country-specific issuance plays a primary role, resulting in far lower economic income. Surely, the consequences billet say-so of spillovers swelling vitality, highlighting the enumeration of equitable access to vaccines across nations. In addition, vaccines have a great impact on education, job employment rate, and people's quality of life. In education, many schools have changed the way of attending classes due to the epidemic, and the cost of attending classes has been reduced. At the same time, it also helps many people to develop and use video software. In addition, as the pandemic has affected the economy, many companies have faced closures and layoffs, leading to a significant decline in employment. We can't imagine how many people will lose their jobs as the companies they work for close down. A decline in employment leads to a loss of wages and reduced consumption, which in turn affects the economy as a whole. So vaccine development tends to increase employment, and companies can work when fewer people are sick. Therefore, it is necessary to discuss the health of the economy.
Empirical analysis of the effectiveness and liquidity of the European carbon emission rights futures market
Authors: Du Xinrui
Published: May 2023

Global warming from greenhouse gas emissions is a worldwide concern and the European Emissions Trading System (EU ETS) is the largest market in the world and has a model role. Some researchers have argued that the carbon emissions futures market was not weakly effective at the beginning of its establishment, but there is a lack of sufficient research on the effectiveness of the market in recent years. Therefore, this study analyses market effectiveness and liquidity by using positions, trading volumes and settlement prices for carbon futures from 2 January 2014 to 23 November 2022, and calculates log returns from settlement prices to construct an ARIMA model for verifying the market efficiency. The analysis finds that the carbon futures market satisfies weak form validity and that the market's macro liquidity and micro liquidity are gradually increasing, and the ARIMA model finds that there is a large seasonality factor in the market. This is mainly related to the maturity of the market, the improvement of the trading mechanism and the global consensus, providing constructive reference for the improvement of the carbon emission rights futures trading market and trading mechanism in China.

The influence of different cultures on international business negotiations & Strategies
Authors: Chen Yixuan
Published: May 2023

International business negotiation is an indispensable part of cross-border and foreign trade. Strategy, psychology, and social context are three important factors in international business negotiation. The strategy includes the preparatory work before the negotiation; the psychological element includes how to understand the mental activities of the other party; the social context also includes the negotiator's country and cultural background. This paper focuses on the analysis of these three elements. It covers the different negotiating priorities and habits of Eastern and Western people or negotiating teams due to cultural differences and includes strategies and countermeasures when facing economic situations. Two strategies are also provided: distributive strategy and comprehensive strategy. Those two refer to people who use both of them in the negotiation, but with different intentions and behaviors. Brett's Model provides a good connection between cultural differences and negotiation priorities for a more in-depth analysis of negotiations throughout the text. From the perspective of limitations, international business negotiations will always be affected by inherent factors, such as cultural differences, different ways of thinking, etc. From a future perspective, this area deserves further research to break the existing inherent problems.
The Relationship between the Gold Price, Crude Oil Price, Exchange Rate and Chinese Stock Market Indexes
Authors: Cui Jinyang
Published: May 2023

One of the trickiest problems for investors is how the financial and commodity markets interact with each other. The volatility in one market might affect the price of the other market. This essay aims to clarify the relationship between gold, crude oil, exchange rates, and Chinese stock market indices. In order to do this, the Shanghai Stock Exchange Index and the China Industrial Index, two indices that reflect the Chinese financial market, were subjected to the DCC-GARCH model (Generalized Autoregressive Conditional Heteroskedasticity Model). By capturing the dynamic correlations of the time series' variance, covariance, and correlation coefficient, this model aids in illuminating the long-run dynamic correlation between returns. The findings show that gold and crude oil are positively correlated with both the Shanghai Stock Exchange Index and the China Industrial Index, while the correlations between the USD CNY exchange rate and the two Chinese stock indices are negatively correlated, using monthly data from 2000-01-03 to 2022-08-30. This paper shows that stock prices in China are weakly linked to international commodity markets and exchange rate with the US. Additionally, throughout the observation period, financial crisis (2008) and the COVID-19 pandemic breakout (2020) enhanced comovement between the Chinese stock market, commodities, and exchange rate in general.

With the frequent economic cooperation between China and United States, culture profoundly affects the way communicate in negotiation. Therefore, it is very important to understand the cultural differences between China and the United States and the impact of these differences on the negotiation. This paper compares the differences in different aspects by studying the literature in the relevant fields and conducting case studies, collectivism versus individualism, communication styles, high power and low power cultures, and high context and low context cultures, while also addressing some ways of expressing emotions and comparing Chinese and American attitudes toward interpersonal relationships. Through the comparative analysis it found that if it reduces the impact of cultural differences in Sino-US business negotiations, the Chinese should understand each other's information in advance, unify internal opinions in advance, and pay attention to improve the content of the contract. The U.S. needs to understand Chinese humanities in advance to show sincerity and at the same time can better promote the establishment of cooperative relations, and at the same time can also better express respect for the other side. In addition, both sides should pay attention to mutual benefit and a win-win situation and should not be too concerned about their interests. This will make the whole negotiation process more smooth and more harmonious. The significance of this research is to help negotiators between the Chinese and American understand each other's culture so that they can reach a satisfactory result in the negotiation.

Authors: Li Zhaorui
Published: May 2023

The complexity and volatility of financial markets place higher demands on the accuracy of stock forecasts. This paper uses Ping An Daily Market Data as the source of experimental data for empirical analysis, and innovatively combines BiLSTM with attention mechanism for stock price prediction in the experimental process. Introduce an attention mechanism, AM, to reinforce important features by reassigning the weight of each data; Bidirectional LSTM can learn sequential and reverse time series data information to ensure adequate data utilization. After establishing BP (backpropagation), LSTM and CNN-LSTM models for comparison, it is found that the proposed AM-BiLSTM model has high accuracy, good feasibility and versatility.
