Authors: Chen Weichen
Published: March 2023

After the Asian financial crisis in 1997, the academic circles turned their attention to the study of the relationship of financial development, economic growth and economic volatility. As an important development industry, the financial industry has a direct impact on global economic growth and economic stability. This paper analyzes the impact mechanism of financial development on economic growth and volatility from the perspectives of the credit market, capital market and financial derivatives market. Taking the macro data of 50 countries from 1997 to 2014 as samples, introducing GDP, government expenditure, trade openness, CPI and other control variables, using individual and time fixed effects, divide the sample into advanced countries and emerging countries, and verify the statistical relationship between financial development and economic growth and economic volatility from the two dimensions of financial development quantity and financial development quality. Besides, the impact of financial development on economic recession is explored. The results show that whether in advanced or emerging countries, the quantity of financial development has an inhibitory effect on economic growth, while the quality of financial development can promote economic growth. Financial development has less impact on economic volatility but has a greater impact on emerging countries than in advanced countries, which will help explain the economic phenomenon that the volatility of emerging countries is higher than that of advanced countries.

Published: March 2023

A good investment portfolio can make the investment get more returns, which requires investors to adopt appropriate methods to optimize the investment portfolio. A portfolio is not just a simple sum of assets, it requires the use of suitable models to analyze optimal asset allocation. This paper analyzes the asset allocation of firefighters, and uses three methods of mean variance analysis, CAPM model and FF3F model to optimize the pension investment ratio of firefighters. At the same time, this paper analyzes multiple stocks from four industries including retail, technology, manufacturing, and food, and strives to find the investment portfolio with the most potential pension. The results show that in CAPM, the largest weights of both maximum sharp ratio portfolio and the minimum portfolio belong to the possession of ‘NSRGY’, while in the FF3F model, the greatest weight of the maximum sharp ratio portfolio belongs to ‘TM’ possession and the greatest weight of the minimum variance portfolio belongs to ‘NSRGY’. This research could help retirees on the same pension type better allocate their pension assets and optimize their investment portfolios. At the same time, this paper also analyzes the investment performance of stocks in different industries under the same fixed proportion of pension.

Published: March 2023

The explosion of the global disaster and the ongoing e-shopping improvements have fueled China’s fast growth in the live shopping industry. This new business paradigm enables merchants to communicate with consumers in a direct way. The goal of this study, which is based on the SOR theory, is to explore critical variables of consumers’ emotional attachment, along with their influence on consumer impulsive buying response within the live streaming scenario. The link between impulse buying behaviour and emotional attachment, moderated by trust, is also examined. A total of 154 usable surveys with “Oriental Selection” purchasing experience are collected. This research uses correlation analysis, ANOVA, and regression analysis to analyse the data. After empirical investigation, the results confirm that content-based sales approach and attractiveness have a significant impact on users’ emotional attachment, which in turn positively affects impulse buying. However, trust is not significantly related to impulse buying behaviour. The research also demonstrates that trust acts as a moderator in the relation between emotional attachment and online impulsive purchasing. Based on the analysis, managerial implications such as providing consumers with eye-opening experiences and adding more entertainment activities are proposed.
Analysis of the Future Trend of the Sino-US Trade War on the Energy Cooperation and Game Between the Two Countries
Authors: Kou Annuo
Published: March 2023

Since the Biden administration took office, it has inherited the Trump administration's perception that China is a major strategic competitor, so China and the United States have entered a competition-oriented dynamic. Political and economic changes around energy will add new instability factors to Sino-US relations and open new areas for China and the US. Under the background of the Sino-US trade war, this paper discusses that America and China, as the most influential representatives of developed and developing countries to achieve global energy goals, the game between the two sides around the economy and other fields will affect the development of Sino-US climate change cooperation status quo. At the same time, the paper studies the existing cooperation foundation under the current context of the intensified energy game between China and the United States, such as new energy vehicle technology. The energy transition is the general trend for the world's largest energy consumer, and carbon emitter. Both countries may achieve a win-win situation by joining hands in energy transition and cooperation to tackle the climate crisis. All possible cooperation will also provide new opportunities for Sino-US relations, but the changes they trigger may exacerbate the existing fierce game, and even create new conflicts. Therefore, accurately grasping the two-way interaction between China and the United States in the energy field is of great benefit to the global energy transformation and the development of green technology.

Published: March 2023

Black-Scholes (BS) model was first proposed in 1973, which has been modified by Robert Merton as the Black-Scholes-Merton (BSM) model subsequently. Contemporarily, these two models have been widely used and praised by financial scholars as well as employees. Plenty of scholars have tried to verify the accuracy of the and expressed their views on the existing defects in above models. Based on the existing literature, this article first introduces and derives the two models step by step and discusses the basic assumptions for these models. Subsequently, the applications of the two models are demonstrated separately. Specifically, the project valuation based on BS model is presented detaily while the applications of BSM model are introduced from four aspects (pricing of intangible assets, risk avoidance, default prediction and employee stock option’s pricing). Afterwards, the limitations and gaps of the models (e.g., volatility smile) ascribed to the ideal assumptions are discussed. In order to tackle the issue, improvement and suggestions are proposed including extending the models with different forms. These results offer a guideline for the option pricing, which can be widely applied in investment strategy.

Global Financial Crisis: Cause, Impact and Response
Authors: Zhang Zhuozhe
Published: March 2023

The subprime crisis is a financial calamity brought on by subprime mortgage companies going bankrupt, investment funds being forced to close, and major stock market shocks. At the start of this century, the US stock market, real estate market, and other asset markets experienced a number of asset bubbles due to excess liquidity, house purchase policy stimulus, financial innovation, and other factors. Along with the tightening of monetary policy, the weakening of the US housing market, and particularly the rise in short-term interest rates, the interest rate for repaying subprime mortgages surged considerably. At the same time, buyers find it challenging to sell their homes or refinance utilising mortgage housing because to the ongoing cooling of the housing market. Due to the failure of many subprime borrowers to make scheduled loan repayments and the failure of banks to sell their properties at high prices, which resulted in significant losses, the subprime crisis was directly caused by these events. Most people agree that the absence of a mechanism for financial monitoring was a major factor in the crisis. The United States has accelerated the adoption of neo liberal economic policies during the past three decades, which is one of the primary causes. However, more than ten years after the United States stabilised the financial system through monetary, fiscal, financial, and other measures, the global economy has been hit considerably more severely and has not yet fully emerged from the shadow of the crisis.

O presente trabalho teve como objetivo fazer uma análise exploratória dos casos suspeitos da COVID19, verificando a quantidade de casos que foram confirmados e descartados e quantos resultaram em internação nos municípios de Pernambuco entre fevereiro e maio de 2020. Além disso, foi feita a mesma análise com as variáveis socioeconômicas dos municípios para, posteriormente, investigar a relação entres as características socioeconômicas das cidades e a disseminação do novo coronavirus na população idosa. Os resultados mostraram que cidades com maior densidade demográfica, maior taxa de urbanização, maior desigualdade de renda e maior nível de renda per capita tendem a ter maiores quantidade de idosos vindo a contrair a COVID-19. Esses resultados sugerem adoção de medidas de isolamento social e de redistribuição de renda como forma de reduzir os contágios do novo coronavirus.

Authors: Saad Mansour Dalia
Published: March 2023

This interdisciplinary study aims to explore the psychological impact of pandemics in cinema with a special reference to Steven Soderbergh’s movie Contagion.  The study refers to Orhan Pamuk’s essay, “What the Great Pandemic Novels Teach Us” (2020), about Pandemic novels where he traces the common initial responses to the outbreak of a pandemic by comparing the current coronavirus pandemic and the historical outbreaks of plague and cholera pinpointing the traits attributed to pandemics and suggesting other psychological defense mechanisms.  In this respect, the study attempts exploring the re-contextualization of Pamuk’s ideologies in cinema through shedding the light on the functions of camera angle shots, colors, sound effects, point of view, and flashbacks.
Orientalism and Periods of Translating the Qur’an: Types and History of Oriental Translations
Authors: Ahmed Abd El-Mageed Ashwaq
Published: March 2023

This study aims to build bridges of thought between the East and the West and to correct the fallacies and negative ideas claimed by the West against the Eastern thought, especially Islam, as an adversary and enemy. The West claimed it as a reactionary thought. The translation movement from Arabic into English, especially Islamic texts, faces great difficulty because English vocabulary is limited to covering Arabic vocabulary, not to mention Islamic vocabulary and expressions that have not yet been adequately translated into English, such as the terms: the unseen and the Day of Resurrection, and their names such as “al-Qāriʻah, al-ṭāmh, al-ṣākhh”. Even the word Ṣalāt  ‘prayers’ is translated by most English translators barring in mind the same concept of prayer in Christianity which is not appropriate and which refers to a lack of English morphological roots. The English morphological roots are about 6000, while the Arabic roots are more than 600,000. In addition to the lack of translated references into Arabic that are related to the research subject.

Authors: Tran Minh Thanh , Pham Ngoc Thach , Dinh Thi Bao Huong
Published: March 2023

This survey was done to uncover the EFL lecturers’ attitudes (cognitive, emotional, and behavioral components) towards the use of information and communication technology (ICT) in teaching English at a university in Vietnam. In addition, the survey also investigated the influence of some teachers' demographic characteristics, including gender, prior ICT training, education level, age, and teaching experience on their attitudes. The author employed a survey questionnaire adapted from Albirini to collect research data. One hundred twelve tertiary EFL teachers answered questionnaires administered online via Google Forms. Quantitative methods and descriptive and inferential statistical techniques were utilized to analyze the collected data. Results indicated that teachers had positive attitudes towards the use of ICT in teaching English. In addition, gender, prior ICT training, education level, teaching experience, and age were found not to impact their attitudes. Finally, this study had some suggestions for future investigations into the attitudes of teachers concerning the use of ICT in English language instruction.

Introduction: Radical cystectomy is associated with high rates of morbidity, prolonged hospital stay, and increased opioid use for postoperative pain management; however, the relationship between postoperative opioid use and length of stay remains uncharacterized. This study serves to investigate the association between postoperative opioid use and length of hospital stay after radical cystectomy. The relationship between patient and surgical factors on length of stay was also characterized.
Methods: We retrospectively reviewed all patients between 2009 and 2019 who underwent radical cystectomy at our institution. Patient and perioperative variables were analyzed to determine the relationship between postoperative opioid use and length of stay using multivariable linear regression analysis.
Results: We identified 240 patients for study inclusion with a median age of 70.0 years. Median length of hospital stay was 10.0 days, with median daily mg morphine equivalent use of 57.5 for patients. Daily mg morphine equivalent use was significantly associated with an increased length of stay, as were previous pelvic radiation, postoperative ileus, and higher Clavien-Dindo grade complication during admission (all p<0.05). Median length of stay increased by one day for each increase of 13.2 daily mg morphine equivalents received.
Conclusions: Increased daily opioid use was associated with increased length of hospital stay after radical cystectomy. Non-opioid-based pain management approaches may be effective in reducing length of stay after radical cystectomy.
