A Humble Blind Singer's Autobiographical Song: Oral Creation Facing a Hong Kong Teahouse Audience
Authors: Yung Bell
Published: June 2023

In 1975, I arranged for the blind professional singer Dou Wun (1910–1979) to sing a traditional narrative genre called naamyam in an old Hong Kong teahouse, three times weekly for three and a half months, facing the teahouse diners. Of the forty-five hours he sang there, he sang an original song composed by himself on his own life for six hours, which he reluctantly did after I pressed him on the idea. It totaled about 1,800 lines of verse, interspersed with spoken prose. In this essay, I shall first report on my concept, construction, and implementation of the fieldwork. Second, I use selected passages from his song to outline his life story. Born to a poor peasant family and blind at three months of age, Dou Wun wandered alone on the streets of Canton from age nine, received training to sing naamyam from a master singer, and finally arrived in Hong Kong in 1926, where he sang in brothels and opium dens. He lived through the difficult periods of the Japanese occupation, changing tastes in entertainment, and the early days of mass media. When times changed and his songs were no longer in demand, he ended up singing on the street. In the last part of the article, I argue for the significance of this epic autobiographical song in world oral literature and assess Dou Wun's creativity and artistry.

The Rise of Online Shopping after the Epidemic in the Perspective of Integrated Marketing Communication
Authors: Zhang Wentao
Published: June 2023

Integrated Marketing Communications (IMC) has been associated with improved sales. Marketers have long relied upon IMC strategies to boost brand awareness, product appeal, and brand discrimination. The COVID-19 pandemic incited e-shopping behavior resulting from limited mobility. To arrest the spread, governments increased travel restrictions. Citizens also reduced movement to curb infections. Until then, shopping was a mobility-driven venture, and consumers readily took to online shopping, which hit $5 trillion in global value. The upward trajectory was maintained even after the restrictions were lifted, raising the question of whether IMC programs influenced post-pandemic e-shopping. This research sought to test IMC stimulation of post-COVID e-shopping. Specifically, the researcher tested IMCs role in maintaining consumer interest and persuading impulse purchase -factors that eventually fostered post-pandemic online shopping. Using qualitative descriptive research, the researcher executed surveys and a case study that revealed IMC as a leading driver of post-pandemic online shopping.

Impact of Stock Repurchase on the Capital Markets
Authors: Mao Wanying
Published: June 2023

This study intends to examine, from an economic and accounting standpoint, how the share repurchase procedure affect financial markets by specifically testing their effects on the financial performance of the specific companies. The OLS regression analysis was used on 66 companies that were traded on the American Stock Exchange between 2009 and 2020 as part of the study sample. The results reveal that share repurchases improve financial results, as evidenced by return on equity (ROE) and Added Economic Value (EVA). The results, however, show that share repurchases have little effect on the return on assets (ROA). The study found that the management's justifications for share buybacks affect a company's financial success. The study also found that the management's aim to produce a cash surplus improves the company's financial performance. The management objective of increasing earnings per share, which also improves the firm's financial success, was found to be one of the most significant motivations for the company to repurchase shares, according to the study. The study also showed that share repurchases significantly outperform returns on assets or returns on equity in terms of the Economic Value Added (EVA), one of the most important measures of financial success. The study, however, found little proof that the companies' share repurchases caused by higher financial leverage have an effect on their financial performance. This research, therefore, provided an insight on how share purchases affect the capital markets is dependent on the source of the surplus cash, and relatedly, share purchases through improved earnings per share increases the desirability of the company from their improving their financial standpoint.

Authors: Meng Lingyan , He Xiaohe , Zhou Mingxuan , Han Xintian
Published: June 2023

After the 2008 financial crisis, hedge funds regained their popularity. Investors naturally wonder whether it is possible to predict and explain hedge fund returns just as its constituents. To answer this question, we examined hedge fund performance of 14 strategies from 2000 to 2017 by separating them into 3 groups. After deriving a statistical model, we applied it to the period of 2017-2022 and examined the errors. We observed that most strategies have a positive risk-adjusted rate of return and the current periods returns have a positive relationship with the previous periods. We concluded that monthly return has too much randomness while 3 strategies yearly returns in the middle quantile could be predicted. More historical return data can improve the accuracy of the model.

On Cooperative Game Approaches For Optimal Portfolio Selection
Authors: Chen Zerong
Published: June 2023

Cooperative game theory is concerned with exploring schemes for allocating payoffs among rational participants in coalitions and has produced several solution designs due to the different emphasis on criteria such as stability and fairness, but this theory has not been widely applied in the field of portfolio selection. In this paper, we explore further applications of the solution concepts of cooperative games based on the model of optimal portfolio selection developed in previous studies, which is modelled in a static form of a non-cooperative zero-sum game between investors and the market and a cooperative game between investors. We propose a risk modified Shapley value based on the tradeoff between return and risk in the financial market based on the Shapley value, and the performance of this solution shows an evident improvement. We also introduce some other solution concepts of cooperative games and give an approach to construct a nucleolus-based portfolio using Maschler's scheme to compute the nucleolus, and the results demonstrate that the allocation schemes based on the cooperative game theory perform well.

Authors: Zhu Kongming
Published: June 2023

A pandemic brings change to health and quality of life, it may also adversely impact financial and food security. These changes also alter how humans react to the situation, sometimes in a very contrasting way from their normal behaviors. Consumer behavior is not general human behavior, it is rather a very specific behavior directed toward the search, purchase, sale, or disposal of goods or services. In times of crisis, consumer behavior can go through a three-step cycle of reacting, coping, and long-term adaptation. The pandemic can also impact food consumption in the face of shrinking income, closure of food service, and managing the household as a unit of consumption in the face of any uncertain shortages. The pandemic has impacted consumer behavior by impacting the shopping habits of people. During the pandemic, impulsive buying was caused by the emotion of fear. These studies used the theory of fear appeal to explain the three important concepts of perceived efficacy, threat, and fear. This theory suggests that fear generates an emotional reaction from customers. Covid-19 has brought extreme challenges for governments, businesses, and societies across the world. These challenges have affected psychological, social, and economic changes. Unemployment without an alternate employment option available during the pandemic has impacted household finances severely. Along with its financial impact it has also caused stress and changed consumer behavior. With the uncertainty that existed and shrinking incomes, the way consumers buy, shop, and consume items changed.

Published: June 2023

This paper investigated whether the China carbon emission right trading policy has effects on the energy industry including coal, electricity consumptions. Moreover, this paper fo-cused on energy industries and showed the mechanism that energy consumption is affected due to a reconstruction of energy structure. The paper employed the DID model to compare energy consumption, industries profitability and market sentiment between the ETS regions and ETS related industries. Some novel results are as follows. First, compared with the non-pilot areas. High carbon-based energy consumptions in the ETS areas are significantly re-duced. This consumption reduction has come at the cost of production firms average prof-itability and net asset to market value. This can result from expectation adjustment of the market investors for the event. Second, because the ETS policy has a gap between the offi-cial announcement and market start-up, this paper considered multiple event times and showed that ETS is a multiple-time event, applying usual DID model may lead to confound-ing results for this. Results show distinct differences on the market reactions and industries reactions for different event times.

Published: June 2023

In this intensifying Sino U.S. trade war, only a sound multilateral trading system can promote the economic development of countries in the context of globalization. In addition to avoiding deeper and broader political confrontation, China and the U.S., which will inevitably have various frictions and disputes in the future, should use international law and international rules to deal with complex international trade disputes. Beyond that, recourse to the WTO dispute settlement mechanism is a key step in resolving the Sino U.S. trade dispute, which requires that we first get the Appellate Body back up and running. Given the lengthy nature of the reform, changes to the consensus rule around the U.S. first should be an alternate solution to reinstate the Appellate Body in the short term.

It discovers both cognitive flexibility and critical thinking are negatively correlated with vulnerability to telecom fraud, meaning that people with more cognitive flexibility and critical thinking were less likely to be telecom scammed. It also finds that people with higher disposable income are also more vulnerable to wire scams. Finally, this study discusses the discovered insights and put forward constructive suggestions for scholars and related departments.

This paper focuses on the development of small companies from an economic perspective by using examples from Coca-Cola and Pepsi. To explain the strategies adopted by Coca-Cola and Pepsi, game theory has been used. Several processes contribute to different outcomes. This paper will demonstrate how other market structures influence supply and demand differently. As a result of the unpredictable variables in the market, determining a price becomes a reactively complex process.
Economic Policy Uncertainty, Corporate ESG Performance, and the Cost of Financing Debt
Authors: Wang Meng
Published: June 2023

This paper examines the relationship between economic policy uncertainty (EPU), corporate ESG performance, and the cost of financing debt using a fixed effect model and finally discusses the impact of corporate ESG performance on the cost of financing debt against the backdrop of economic policy uncertainty. The results of this paper show that EPU has a positive impact on financing costs, but corporate ESG performance has a mitigating effect on this effect. According to the construction standards of ESG rating indicators, this paper further explores the impact of corporate ESG disclosure on the cost of corporate financing debt under the background of economic policy uncertainty. It concludes that ESG disclosure has the same moderating effect as ESG performance, and the effect of ESG disclosure is stronger.

Authors: Fritz Okta Nehemnya  , Madju Yuni Ros Bangun
Published: June 2023

The public sector in Indonesia is often regarded as a sector with stable employee turnover, possibly considered almost non-existent. However, the VUCA (volatile, uncertain, complex, and ambiguous) era has exerted pressure on employees within the Ministry of Finance (MoF) due to both global pressures (e.g., low economic growth) and domestic demands (e.g., high expectations for public services and societal way of life). The high job demands and societal pressures on employees at the MoF have created an exceedingly demanding work environment. Therefore, the research measures turnover intention (TI) which is found extremely high according to internal surveys (46%). This study explores the factors contributing to the high TI by predicting work engagement (WE), perceived organisational support (POS), and happiness as independent variables. Research data was collected through surveys (n=183) and analysed using Partial Least Squares, Structural Equation Modelling (PLS-SEM). The findings demonstrate the diverse impacts of WE (2.881>1.96 t-table; sig 0.004<0.10), POS (3.305>1.96 t-table; sig 0.001<0.10), and happiness (1.541<1.96 t-table; sig 0.123>0.10) to TI. Two hypotheses were supported, while one hypothesis was rejected, indicating the need for further research in the public sector environment.

Aceh Tamiang Regency is an expansion area of East Aceh Regency. This district is located in the strategic East Sumatra route and is only approximately 136 km from the city of Medan, the capital of North Sumatra. This district is directly adjacent to the province of North Sumatra and is the gateway to enter the province of Aceh. There are 77 tourist attractions scattered in the Aceh Tamiang area, which are worth a visit. Potential tourist attractions are spread over 12 (twelve) sub-districts, both natural, cultural-historical and artificial. several problems to build tourist destinations in Aceh Tamiang Regency, including accessibility to tourism objects still looks damaged. Maintenance of damaged roads has not yet been carried out by the district government. The results of the study indicate that the position of tourism development in Tamiang Regency is in Quadrant III, meaning that tourist attraction has a very large opportunity but on the other hand faces several internal weaknesses. The strategy that can be applied in this situation is a turn-around strategy, which is a strategy to minimize weaknesses by taking advantage of existing opportunities. The focus of this strategy is to minimize internal constraints.

The method used in this study is library research. The sources used are primary sources, namely Tafseer al-Munīr as a material object, and criticism of feminism as a formal object, while the secondary sources are journals, books, commentaries, websites, and other sources that support this research. This method uses content analysis method which is carried out with critical thinking. The results of this study indicate that menstruation (mahidh) in Surah Al-Baqarah verse 222, which is interpreted as dirty blood by Az-Zhuhaili, has received criticism from Indonesian Muslim Feminism. According to feminism, menstruation is an adza (disease) that affects the physical and psychological state of women. Then, the conclusion in this study is that feminists consider that Wahbah az-Zhuhaili's view related to menstruation is still textual, judging from his interpretation, az-Zhuhaili tends to take the opinion of classical scholars who should have contemporaries Muslims tend to have a contextual view.

Published: June 2023

BACKGROUND AND OBJECTIVE
Cavernomas are well-circumscribed and multilobulated vascular malformations that can occur nearly anywhere in the body. Cavernomas are found 80% supratentorially, 15% in posterior fossa and only 5% in the spinal cord. Spinal cavernomas are most commonly intramedullar. Purely epidural spinal cavernoma constitute of less than 4% of all spinal epidural lesions. We report a case of histopathologically confirmed epidural cavernoma of the thoracic spine.

CASE PRESENTATION
A 24-year-old woman presented with a 6-month history of progressive chronic upper back pain. Physical examination revealed no neurological deficit. Her VAS pain scale was 6/10. Conservative treatments did not relieve her symptoms.
Thoracal MRI without contrast shown a lesion that hyperintense on T2-weighted images and isointense on T1-weighted images. The lesion sized 14x13x7 mm at T5 vertebral level located at posterolateral spinal canal. Thoracal MRI with contrast showed extradural mass with homogenous contrast enhancement. The mass was located at left posterolateral spinal canal suspected extradural meningioma.
The surgery was done via posterior approach. Left hemilaminectomy was done at T4-T5 vertebral level. Reddish soft tissue mass was observed at the epidural space. The mass was well defined and there were no signs of bony invasion. Gross tumor removal was done under the microscope. Histopathological examination of the mass showed large dilated vessel filled with erythrocyte and lined by endothelium which support the diagnosis of cavernoma. After the surgery, her pain symptom was improved.

CONCLUSION
Spinal epidural cavernomas are rare, but it should be considered as one of the differential diagnosis for spinal epidural lesions. Exact preoperative diagnosis is hard because there are no pathognomonic MRI findings of spinal epidural cavernoma. Total surgical resection of the lesions was the treatment of choice in symptomatic patients to prevent progressive neurological deficit and prospective hemorrhage.
